Description

The technical field to which the invention relates.

The present disclosure relates to a laundry treating device having a door for opening / closing a hole for loading laundry of the main body and a method for producing a door of the laundry treating device.

Prior art

A laundry treating device (or a clothes treating device) includes a laundry washing device, a laundry drying device, a laundry washing and drying device. In the laundry treating device, laundry is related to the cycle of removing contaminants adhering to the laundry due to the action of water and detergent, and drying the laundry refers to the cycle of removing moisture contained in the laundry using a hot air supply device located in the treatment unit linen.

The known laundry treating device may include a main body forming its appearance and having an opening for loading the laundry, a region for placing the laundry formed in the main body, a driving unit rotating the drum forming the laundry placement portion, a door opening and closing a hole for loading laundry, and a control unit displaying visual information related to the cycles performed in the laundry treatment device for the user and receiving user commands.

In the known device for processing linen, the door is adapted to open and close the opening for loading the linen and to provide the user with an overview of the internal area for placing the linen. In addition, the control unit is usually mounted on the main body and contains many buttons or knobs for briefly displaying only a predetermined mode when turning on / off and controlling such brief output data.

The separate design of the door and control unit interfered with the simple appearance of the laundry treating device, and the input and output interfaces between the laundry treating device and the user had no choice but to stay low.

Accordingly, studies are being carried out on the placement of the control unit on the door and the execution of the control unit in the form of a touch screen. Related technologies are disclosed in Korean patent, laid out for public inspection, no. 10-2011-0130089 (published December 5, 2011) and Korean Patent Laid Out for Universal Examination, no. 10-2015-0006264 (published January 16, 2015). However, the prior art, which includes these patent publications, did not reveal the combination between the door cover and the touch screen and the combination between the touch screen and the display unit, which will be explained below.

To form a touch screen on the door, the touch screen and the display unit must be located in the light-transmitting area (transparent area) of the door cover in an appropriate (or combined) way. Specifically, in a design in which the tactile sensor is made separately from the display unit and mounted on the back surface of the door cover, the tactile sensor must be fixed in the exact position on the door cover to ensure the reliability of the touch screen.

Essentially, when implementing the touch screen, it is necessary to combine the door cover and the tactile sensor, and the tactile sensor with the display unit. At the same time, taking into account the assembly process, the combination between the door cover and the tactile sensor must first be carried out accurately.

Brief description of the invention

Therefore, one of the objectives of the present invention is to create a structure for combining between a door cover and a tactile sensor and a structure for combining between a tactile sensor and a display unit to form a display area in the form of a touch screen when a window is installed on the door that provides an overview of the inside laundry area and a display area displaying information processed in the laundry treating device.

Another task is to create a structure that prevents the visibility of components that are made with the possibility of fixing a tactile sensor in a predetermined position on the door cover, on the outside of the door.

Another task is to create a tactile sensor, on which components are displayed (indicated) for alignment with the door cover.

To solve these problems, a laundry treatment device is proposed, which includes a main body having an opening for loading laundry and a door opening and closing the opening for loading laundry, the door including a door lid forming the appearance of the door and containing a transparent area and the opaque area surrounding the transparent area, the display unit, located on the rear surface of the door cover and displaying visual information through the transparent area, and a tactile sensor attached and the rear surface of the door cover for closing the transparent region and defining a touch input applied to a transparent area, wherein the sensor comprises a tactile alignment mark to provide tactile sensor fixing in the correct position relative to the transparent area.

The alignment mark may include at least two alignment points formed in the corner portions of the tactile sensor, respectively.

The alignment mark may include a alignment line extending along at least one side of the tactile sensor.

The tactile sensor may include a base made of a transparent material, a touch pattern printed on a predefined pattern on the base to determine the touch input used on the door cover, and a mark formed on the base and forming an alignment mark.

The alignment mark can be made of the same material as the touch design, but electrically separated from the touch design.

The tactile sensor may further include a signal transmission portion electrically connected to the touch pattern to form a signal transmission channel. The label can be made of the same material as the signal transmission section and electrically separated from the signal transmission section.

The door lid may include a body made of a transparent material and a protective layer disposed to cover the rear surface of the body of the lid and forming an opaque area.

The transparent area may be an area where the protective layer is not located.

The transparent area may be an area where the protective layer is not located.

The door lid may include a body made of a transparent material and a film attached to the back surface of the body of the lid, and the film may include a transparent portion corresponding to the transparent region and a non-transparent portion formed to surround the transparent portion and corresponding to the opaque region .

In addition, the present disclosure discloses a method for manufacturing a door of a laundry treating device, the method comprising forming an opaque area on one surface of a door cover made of transparent material, with the possibility of surrounding the transparent area, and fixing a tactile sensor on one surface of the door cover, a tactile sensor detects a touch input used in a transparent area, with the tactile sensor attaching the registration of the tactile registration mark sensor based on the boundary between the opaque area and the transparent area.

The registration can be performed in such a way that the registration label is located to overlap the opaque area forming the border. In this case, the alignment mark may have a color tone that is different from the opaque area.

The registration can be performed in such a way that the registration label is positioned to overlap the transparent area forming the border. In this case, the manufacturing method may additionally include, after securing the tactile sensor, securing the opaque security element on the tactile sensor with the possibility of closing the registration mark. The security element may be positioned to overlap the transparent area. The security element may have the same color tone as the opaque area.

The manufacturing method may additionally include the location of the display unit to close the transparent area after fixing the protective layer.

The manufacturing method may further include changing the door cover to a curved shape by pressing after forming an opaque area.

In accordance with the present invention, a more accurate alignment of the tactile sensor relative to the door cover can be achieved by forming a registration mark on a portion of the tactile sensor that does not correspond to the second transparent area and combining the registration mark on the basis of the border between the opaque area and the transparent door area.

In addition, the supporting door frame guide may include a first protruding portion in a rounded shape and a second protruding portion in a linear shape, which correspond to the first and second edges of the door cover, respectively. Accordingly, when assembling a door cover with a door frame, the second edge and the second protruding portion can function as set points for aligning the installation position. That is, when the second edge is adapted to conform to the second protruding portion, the door lid may be located in a fixed position on the door frame, and thus the first and second transparent areas of the door lid may be configured to align with the first and second door openings. frame. Thus, the door lid may be located in a fixed position on the door frame, which may lead to alignment between the tactile sensor mounted on the door cover and the display unit connected to the door frame.

When the touch pattern of a tactile sensor is made in the form of a metal mesh design, the label can be made of the same metal material as the touch pattern, but electrically separated from the touch pattern with the possibility of forming a blank portion in which the touch input is not detected. In the case of such a design, a simple layered structure can be implemented in terms of the formation of a sensory pattern and a label using a single-layer metallic material, and the label and the sensory pattern can be performed during the same process.

When a tactile sensor includes a touch pattern using indium and tin oxides and the like, and a signal transmission area, the tactile sensor may have the following two designs.

First, the label can be made of the same material as the signal transmission section, but electrically separated from the signal transmission section. In this case, the label and signal transfer section can be performed during the same process, rather than using separate processes.

The label can be made of a material different from the material of the signal transmission section, and thus, the label and the signal transmission section can be implemented by different processes. In this case, a tactile sensor having an alignment mark can be performed using a simple marking process on a prefabricated tactile sensor.

Additional scope of this application will become clearer from the detailed description below. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become clearer to those skilled in the art from the detailed description.

Detailed Description of the Invention

In the following, a laundry treating device according to the present invention will be described in more detail with reference to the accompanying drawings.

The expression in the singular may include the expression in the plural, as long as it does not have a distinctly different meaning from the context.

Although different embodiments are illustrated, the same or similar elements as the elements of the above embodiment may be denoted by the same or similar reference numbers, and the description will not be repeated.

In addition, when describing the present invention, the detailed description will be omitted when the specific description of the widely known devices to which the invention relates is considered as complicating the understanding of the essence of the present invention.

The accompanying drawings are used to provide an easy understanding of the various features, and it should be understood that the embodiments described in this document are not limited to the accompanying drawings. Essentially, the present disclosure should be construed to extend to any changes, equivalents, and replacements in addition to changes, equivalents, and substitutions, which, in particular, are presented in the accompanying drawings.

FIG. 1 is a perspective view of the laundry treating device 1 in accordance with one embodiment of the present invention; FIGS. 2A and 2B are conceptual views illustrating the open position of the laundry load hole 20a as a result of the primary and secondary turns of the door 10 shown in FIG. 1, respectively.

As shown in these drawings, the laundry treating device 1 may include a main body 20 and a door 10.

The main body 20 may form the appearance of the laundry treating device 1, and comprises a laundry opening 20a through which the laundry is loaded into the main body 20. This exemplary embodiment illustrates that the laundry loading opening 20a is formed in the front portion of the main body 20 in hexagonal shape.

The main body 20 may have an area for placing the laundry in which the laundry is placed through the opening 20a for loading the laundry.

For example, in the case where the laundry treating device 1 in accordance with the present invention is made in the form of a laundry drying device, the laundry placement area may be in the form of a drum 40 rotatably mounted in the main body 20.

As another example, in the case that the laundry treating device 1 according to the present invention is designed as a device that can do both washing and drying the laundry, the laundry placement area can be formed with a tank (not shown), located in the main body 20 for storing water for washing, and the drum 40 mounted rotatably in the tank, to accommodate linen.

The main body 20 may include a drive unit (not shown) that rotates the drum 40. The drive unit may include a motor that generates a driving force and a belt that rotates the drum 40 using a driving force.

The main body 20 may include a container for supplying detergent (not shown), which is installed with the possibility of extension and insertion like a drawer. The cover 21, which closes the container for the supply of detergent, can be made to rotate up and down.

The main body 20 may include a power button 22 for turning the laundry treating device 1 on or off. When the display section 12, which will be described below, is configured as a touch screen, the laundry treating device 1 may be turned on / off by using touch input on the touch screen 12. In this example, the power button 22 may not be used, and thus can be provided with a simpler appearance of the device 1 for processing linen.

The door 10 may relatively rotate relative to the main body 20 to open or close the laundry inlet 20a. As shown, the door 10 can be pivotally mounted relative to the main body 20 by means of the hinge assembly 30.

The main body 20 may comprise a door housing portion 20b recessed on the outer surface and having a hole 20a for loading laundry. When the door 10 is closed, the door 10 can be placed on the portion 20b for accommodating the door, and the edge of the outer surface of the door 10 can be located flush with the adjacent outer surface of the main body 20.

Regarding the structure in which the door 10 is located on the door accommodation portion 20b, to prevent the door 10 from locking on the main body 20, the hinge assembly 30 may have a double hinge structure having two different pivot shafts. In this case, as shown in FIGS. 2A and 2B, the door 10 may be located at a distance from the laundry placement section 20b due to the primary rotation relative to one of the two rotary shafts, and then the rotation due to the secondary rotation relative to the other rotating shaft .

In a construction in which the hinge assembly 30 is installed on one side of the door 10, the locking device for locking or unlocking the door 10 relative to the main body 20 may be located on the other side of the door 10. The locking device may be configured to be clamped. Accordingly, the door 10 can be locked by pressing the other side of the door 10 once and unlocking by pressing one more time.

The door 10 may include a window 11 and a display section 12.

In the closed position of the door 10, the window 11 may be positioned to refer to the hole 20a for loading laundry, so that the inside of the section for accommodating the door is visible through it. Thus, the window 11 can provide the user with checking the position of the laundry placed on the laundry location through him.

The display portion 12 may display information processed in the laundry treatment apparatus 1. For example, the display section 12 may display the execution information on the screen regarding cycles (washing, dehumidifying, drying, etc.) performed in the laundry treatment device 1, or user interface (UI) information, a graphical user interface (GUI) corresponding to the performance information on the screen.

Below will be described the detailed construction of the door 10.

FIG. 3 is an exploded perspective view of the door 10 shown in FIG. 1, and FIG. 4 is a front view of the door 10 shown in FIG. 1. FIG.

As shown in FIGS. 3 and 4, door 10 may include door frame 110, door window 120, display unit 130, and door cover 140. As mentioned above, door 10 contains a hinge 30 for connection to the main body 20, but a hinge node 30 is removed from these drawings.

In this exemplary embodiment, it is shown that the door 10 is made in a round shape (including a regular round shape, an oval shape or a round shape with at least a rounded portion). However, the present invention may not necessarily be limited to this form. The door 10 may also be made in a polygonal shape (rectangular shape, hexagonal shape, etc.).

The door frame 110 may be rotatably connected to the main body 20, and for this purpose, the hinge assembly 30 may be connected to the door frame 110 and the main body 20, respectively.

As shown, the door frame 110 may include an outer frame 111 and an inner frame 112. The outer frame 111 and the inner frame 112 may be made of synthetic resin (for example, ABS, polycarbonate, etc.).

For reference, these components are called the outer frame 111 and the inner frame 112, since the outer frame 111 faces the outer side of the main body 20, and the inner frame 112 faces the inner part of the main body 20 when looking only at the door frame 110 in the closed position of the door 10 Alternatively, the outer frame 111 and the inner frame 112 may also be referred to as the first and second frames, respectively, without such a difference.

The door frame 110 may include a first opening 110a facing the opening 20a for loading laundry, and a second opening 111b corresponding to the display unit 130 mounted inside in the closed position of the door 10. The first opening 110a may also be referred to as an opening for a window in aspect wherein the door window 120 is located on the first opening 110a, and the second opening 111b may also be referred to as an indicator opening in an aspect in which the display unit 130 is mounted on the second opening 111b. The second opening 111b may be located above the second opening 110a.

The first opening 110a may include a front opening 111a formed on the outer frame 111, and a rear opening 112a formed on the inner frame 112. A second opening 111b may be formed on the outer frame 111. A connecting portion 112b may be formed above the rear opening 112a frame 112. The display unit 130 can be installed in the door frame 110 through the connecting portion 112b.

The door window 120 may be mounted on the door frame 110 to correspond to the first hole 110a. The door window 120 may be made of a transparent material (glass, synthetic resin, etc.) and positioned to access the laundry inlet 20a in the closed position of the door 10.

The display unit 130 may be installed in the door frame 110. The display unit 130 includes a support frame 131 and an indicator 132. The display unit 130 may be located to match (to align with) the second opening 111b, and the indicator 132 located on the support frame 131 may display visual information associated with the information processed in the laundry treatment apparatus 1.

In addition, an opening 111c for a flexible printed circuit board (FPCB) through which FPCB 161 can be inserted (see FIG. 5) of the tactile sensor 160 can be formed on the door frame 110. In the drawings, it is shown that the opening 111c for FPCB is located on one side of the second hole 111b.

A door lid 140 forming the appearance of the door 10 may be connected to the door frame 110. The door lid 140 may be made of glass or synthetic resin having transmissive ability (or light transmission).

The door lid 140 may include an opaque region 143 and a first transparent region 141 corresponding to the first aperture 110a, and a second transparent region 142 corresponding to the second aperture 111b in the opaque region 143. In this document the transparent region (or the light transmitting region) indicates the region through which transmits at least part of the world, so that the opposite side or the inner side is visible. Therefore, a transparent region can be understood as a concept that includes a translucent region.

The first and second transparent areas 141, 142 can be separated from each other by an opaque area 143. In this embodiment, the door frame 110 and the door cover 140 are formed in a circular shape to match the round door 10, and the first and second transparent areas 141, 142 are formed in a round shape for evoking a general feeling of unity from a single form. In this document, the round shape includes a round, oval, or round with at least a rounded portion.

As reference information, these components in circular form are illustrative only, and the present invention may not be limited to this. For example, the first and second transparent regions 141, 142 may be formed in a polygonal shape (eg, rectangular, hexagonal, etc.) or other geometric shapes, in addition to the round shape.

The door lid 140 may have at least a portion formed in a curved shape. For example, based on the curved portion of the door cover 140, the first and second portions of the cover on both sides of the curved portion may be inclined towards each other. In this document, the first section of the cover and the second section of the cover can be made in a flat shape. To fit the shape of the door cover 140, the door frame 110 may also have at least a portion formed in a curved shape.

In this exemplary embodiment, the first transparent region 141 is formed in the first portion of the lid and the curved portion, and the second transparent region 142 is formed in the second portion of the lid.

In this case, the second transparent region 142 may be smaller in size than the second opening 111b, and is located in the second opening 111b with the possibility of overlap in a position in which the door cover 140 is connected to the door frame 110. In this document, overlap means overlapping in the thickness direction of the door 10 In accordance with such a construction, the outside line forming the second opening 111b is not visible due to the opaque region 143.

In addition, the display unit 130 is located in the second hole 111b. The second transparent area 142 may be located within the indicator 132, which is located on the display unit 130 with the possibility of overlap. In accordance with the design, and only the indicator 132 for displaying visual information is open to the outside, other device designs (for example, the support frame 131) may not be opened outside due to the opaque region 143, which may result in a more simplified appearance of the door 10.

In addition, the edge area (i.e., the frame area) of the indicator 132 corresponds essentially to the area that does not display visual information due to the limitation of the design. If the edge region is located in the second transparent region 142, the visual information displayed on the indicator 132 may be displayed on a smaller screen than the second transparent region 142. In this case, the user may feel that the visual information display screen is smaller than the actual size.

To solve this problem, the edge region of the indicator 132, on which no visual information is displayed, can be arranged to be closed by the opaque region 143. According to the design, the visual information displayed on the indicator 132 can form a screen that fully corresponds to (fully fits) the second transparent area 142. In this case, the user may feel that the screen for displaying visual information is larger than the actual size and, accordingly, may go deeper into the screen. Ana.

As shown, the second opening 111b may have a rectangular shape corresponding to the display unit 130 having a rectangular shape, and the second transparent region 142 may have a circular shape located in the second opening 111b with the possibility of overlapping. That is, the second transparent area 142 may be located to overlap part of the display unit 130, and the opaque area 143 may be located to close another part of the display unit 130. In the case of this construction, the visual information can only be displayed on the portion of the display unit 130 corresponding to the second transparent region 142, thus providing the user with the display portion 12 in a circular shape.

A round indicator is more expensive than a rectangular indicator, which is widely used, and is also difficult to establish the exact installation position in terms of its shape, which can often cause improper assembly. However, when using such a construction in accordance with the present invention, a rectangular indicator 132, which requires less manufacturing cost and can be assembled in a precise position, can be used, and also a display area 12 that looks circular can be provided to the user.

The second transparent area 142 may be surrounded by an opaque area 143, and, accordingly, the visual information displayed on the portion of the indicator 132, which does not correspond to the second transparent area 142, may not be visible to the user. Taking this into account, the visual information may not be displayed on the portion of the indicator 152, which does not correspond to the second transparent area 142.

For example, while the visual information associated with the information processed in the laundry treating device 1 is displayed on the indicator portion 132 corresponding to the second transparent area 142, the outer image surrounding the visual information may be displayed on the indicator portion 132 without matching the second transparent region 142. The outer image may be a region that does not correspond to the second transparent region 142, and be filled with a specific color tone (for example, black).

As another example, in a position in which the visual information processed in the laundry treating device 1 is displayed on the indicator area 132 corresponding to the second transparent area 142, the indicator area 132 without matching the second transparent area 142 can be turned off. That is, the portion of the indicator 132 without matching the second transparent region 142 may not display the external image, as well as visual information. In this exemplary embodiment, only a portion of the indicator 132 can be turned on, respectively, the indicator 132 can be more effectively activated than the aforementioned embodiment of turning on the entire indicator 132, leading to a power saving effect.

FIG. 5 is a rear view of the door cover 140 shown in FIG. 3. FIG.

The display portion 12 located on the door cover 140 may be located or integrally formed with the tactile sensor 160, thus realizing the touch screen 12. The touch screen 12 may function as a user input device that forms the input interface between the processing device 1 linen and the user, and at the same time form the output interface between the device 1 for processing linen and the user. For example, the selection and change of the operating mode for performing washing cycles, removing moisture, drying and the like may be accomplished by using the user's touch input (or touch) on the display section 12.

The tactile sensor 160 may be located on the door 10 to determine the sensory input used on the door cover 140.

The tactile sensor 160 may determine the sensory input that is used in the display area (or touch screen) using at least one of various sensory methods, such as resistive method, capacitive method, infrared method, ultrasonic method, magnetic method, and like that

As one example, the tactile sensor 160 may convert the change in pressure applied to a particular portion of the touch screen 12, or capacitance generated at a particular portion, into an electrical input signal. The tactile sensor 160 may be configured to determine a touch position, a touch region, a touch pressure, or the like, which are determined by the touch object using the touch on the touch screen. In this document, a touch object may be an object using a touch to a tactile sensor 160, for example, a finger, a stylus for a touch screen, a touch pen, a pointer, or the like.

Thus, when there is a touch input (inputs) applied to the tactile sensor 160, the tactile sensor 160 can send the corresponding signal (s) to the control unit. Then, the control unit can transmit which area of the display portion 12 has been touched. In this document, the control unit can be a component, separate from the controller, or the controller itself.

In this case, the controller can perform other control operations or the same control operation in accordance with the type of touch object applied to the touch screen 12. Whether to perform another control operation or the same control operation in accordance with the type of touch object can be determined in accordance with the operating state of the laundry treatment device 1 or the application currently running.

The tactile sensor 160 may detect various types of touches applied to the touchscreen 12. Examples of various types of touches may include a short touch or a touch touch, a long touch, a multiple touch, a slow touch, a quick touch, a touch with a stroke, a touch with a stroke, touch with holding the finger in a horizontal direction, touch with guidance and the like.

The tactile sensor 160 may determine a sensory input used in the sensory region including the second transparent region 142.

In this exemplary embodiment, it is shown that the tactile sensor 160 is glued to the back surface of the door lid 140 so that the second transparent region 142 and the part of the opaque region 143 surrounding the second transparent region 142 can be closed. even part of the opaque region 143 surrounding the second transparent region 142, as well as the second transparent region 142. Therefore, it may be possible to form various user interfaces. ysov or graphical user interface using a part of the opaque region 143 surrounding the second transparent region 142.

In this design, the tactile sensor 160 may be made in the form of a touch film having a touch pattern and located between the door cover 140 and the display unit 130. The sensor film can be made of a transparent conductive film, and a film of indium and tin oxides (ITO), a carbon nanotube film (CNT), and the like can be used as a touch film.

The sensor film can be made with a single or double layer. For example, when the sensor film forms two layers (glass film-film (GFF)), the sensor film may be glued to the back surface of the door cover 140 or to the display unit 130. As another example, when the sensor film forms a single layer, the sensor film may be glued to the back surface of the door cover 140 in a single-piece shape.

The tactile sensor 160 can also be made using the method of forming a pattern of metal wire directly on the back surface of the door cover 140 without a separate touch film (only G2: glass).

The tactile sensor 160 may be made in one piece with the indicator 132 located on the display unit 130. For example, the tactile sensor 160 may be located on the substrate of the indicator 132 (per cell) or located in the indicator 132 (in the cell).

In this case, the display portion 12 of the laundry treating device 1 can be operated under the control of the controller. That is, the controller can control the on / off of the display unit 130, the display of visual information or the image, and the on / off of the tactile sensor 160.

In this document, the controller can control whether or not the touch detection applied to a portion of the sensory area of the tactile sensor 160, which does not correspond to the second transparent region 142, is activated. For example, by determining whether a touch definition applied to the sensing region of the tactile sensing 160 is necessary or not. without matching the second transparent region 142, the contact perception with respect to the non-compliant area may be deactivated in the unnecessary state of contact perception. In accordance with the control, an error that probably occurs when the user applies a touch input can be reduced, and an energy saving effect can be obtained.

FIG. 6 is a sectional view of the first embodiment of the door cover 140 taken along line A-A ′ shown in FIG. 5.

As shown in FIG. 6, the door cover 140 may include a housing 140a and a protective layer 140b.

The cover body 140a may be made of a transparent material. The cover body 140a may also be made of clear glass or synthetic resin. The cover body 140a may have at least a portion formed in a curved shape.

The protective layer 140b may cover one surface of the cover body 140a to form an opaque region 143. The protective layer 140b may be formed on the front surface or the rear surface of the cover body 140a.

In this exemplary embodiment, it is shown that the protective layer 140b is formed by ink printing on the back surface of the cover body 140a. The ink may contain a pigment with a specific color tone (for example, black, white, blue, etc.). Alternatively, the protective layer 140b may be formed using various printing methods, such as screen printing (using a mesh made of silk, nylon, a mixture of polyester and viscose, stainless steel, etc.), offset printing, transfer printing and the like.

As shown, the protective layer 140b may not be located in the first and second transparent areas 141, 142. In other words, the first and second transparent areas 141, 142 may be transparent areas in which the transparent cover body 140a is left without closure by the protective layer 140b.

The protective layer 140b is formed to surround the first and second transparent regions 141, 142. The first and second transparent regions 141 and 142 are separated by an opaque region 143 formed by the protective layer 140b.

The tactile sensor 160 is fixed to the rear surface of the cover body 140a corresponding to the second transparent area 142. The tactile sensor 160 is located to completely close the second transparent area 142 to determine the touch input used in the second transparent area 142. The tactile sensor 160 can be formed larger than the size of the second transparent region 142. In this case, the tactile sensor 160 may be configured to close a portion of the protective layer 140b bounding the second transparent region 142.

In this case, in the case of this design, the tactile sensor 160 and the transparent cover body 140a are arranged sequentially on the front side of the indicator 132 located on the display unit 130.

FIG. 7 is an enlarged view of part B shown in FIG. 5. FIG.

As shown in FIG. 7, the protective layer 140b, which bounds the first transparent region 141 of the door cover 140, can be designed in such a way that its transparency gradually changes to the first transparent region 141.

For example, the opaque region 143 around the first transparent region 141 may gradually be transparent to the first transparent region 141. For this purpose, the protective layer 140b may include a plurality of security points 140b 'that are formed around the first transparent region 141. The plurality of security points 140b' may be performed with a density that gradually decreases towards the first transparent region 141.

By blurring the border of the first transparent region 141 using such a halftone method, the region from the opaque region 143 to the first transparent region 141 can be naturally seen.

On the other hand, the second transparent region 142 and the opaque region 143 surrounding it can obviously be separated by an opaque region 143 in the form of a border.

FIG. 8 is a sectional view of a second embodiment of the door cover 140 along line A-A ′ shown in FIG. 5.

Unlike the aforementioned first embodiment, in which the protective layer 140b is printed on the back surface of the lid body 140a, in this embodiment, the film 2140b is shown to form an opaque region 2143 glued to the back surface of the lid body 2140a.

As shown in FIG. 8, the film 2140b may include an opaque portion 2140b3, corresponding to the opaque region 2143, a first transparent portion 2140b1, corresponding to the first transparent region 2141, and a second transparent portion 2140b2, corresponding to the second transparent region 2142. The opaque portion 2140b3 may be configured to surround the first and second transparent sections 2140b1 and 2140b2. The first and second transparent portions 2140b1 and 2140b2 can be separated from each other by an opaque portion 2140b3.

In this document, the portion corresponding to the opaque portion 2140b3 may function as a protective layer that makes the door cover 2140 opaque and forms an opaque region 2143. The portions corresponding to the first and second transparent portions 2140b1 and 2140b2 may form the first and second transparent regions 2141 and 2142 respectively, together with the transparent cover body 2140a.

That is, unlike the above-mentioned first embodiment, the first and second transparent regions 2141 and 2142 can be formed by arranging transparent portions of the film 2140b, that is, the first and second transparent portions 2140b1 and 2140b2, on the transparent cover body 2140a.

The tactile sensor 2160 is glued to the back surface of the film 2140b, corresponding to the second transparent section 2140b2. The tactile sensor 2160 is located to completely close the second transparent area 2142 with the ability to determine the touch input used in the second transparent area 2142. The tactile sensor 2160 can be formed larger than the size of the second transparent area 2142. In this case, the tactile sensor 2160 can cover part of the opaque section 2140b3, limiting the second transparent section 2140b2.

In this case, in the case of this design, the transparent tactile sensor 2160, the second transparent section 2140b2 of the film 2140b, and the transparent cover body 2140a are arranged sequentially on the front side of the indicator 132 located on the display unit 130.

FIG. 9 is a sectional view of the third embodiment of the door cover 140 along line A-A ′ shown in FIG. 5.

Like the aforementioned second exemplary embodiment, in this exemplary embodiment, the film 3140b is shown to form a protective layer 3140b attached to the back surface of the cover body 3140a. As shown in FIG. 9, the film 3140b may include an opaque portion 3140b3 corresponding to the opaque region 3143, a first opening 3140b1 corresponding to the first transparent region 3141, and a second aperture 3140b2 corresponding to the second transparent region 3142. The opaque portion 3140b3 may surround the first and second openings 3140b1 and 3140b2, and the first and second openings 2140b1 and 2140b2 can be separated by an opaque portion 3140b3.

In this document, the portion corresponding to the opaque portion 3140b3 functions as a protective layer that makes the door cover 3140 opaque and forms an opaque region 3143. The first and second openings 3140b1 and 3140b2 can be formed in the portions corresponding to the first and second transparent regions 3141 and 3142 Accordingly, the first and second openings 3140b1 and 3140b2 can open the transparent cover body 3140a without a film 3140b located on them.

The tactile sensor 3160 is mounted on the rear surface of the cover body 3140a corresponding to the second transparent area 3142. The tactile sensor 2160 is located to completely close the second transparent area 3142 with the ability to determine the touch input used in the second transparent area 3142. The tactile sensor 3160 can be formed larger, than the size of the second transparent region 3142. In this case, the tactile sensor 3160 may cover part of the opaque portion 3140b3 bounding the second opening 3140b2.

In this case, in the case of this design, the transparent tactile sensor 3160 and the transparent cover body 3140a are arranged in series on the front side of the indicator 132 located on the display unit 130. This may be essentially the same as the layered structure shown in FIG. 6, with a slight difference in thickness between the protective layers 140b and 3140b.

The layered structure shown in FIGS. 6 and 9 provides the following effects as compared to the layered structure shown in FIG.

First, the tactile sensor 160, 3160 is directly attached to the transparent cover body 140a, 3140a, which may increase the tactile sensitivity that the user senses. In addition, unlike the layered structure shown in FIG. 8, the second transparent portion 2140b2 of the film 2140b is not located on the front side of the indicator 132, which can provide a clearer display of visual information on the indicator 132.

In this case, the method of fixing the film 2140b, 3140b on the door cover 2140, 3140, shown in FIGS. 8 and 9, can be cast in a mold, a transfer method, and the like.

Mold casting is a method that can be used when the door lid 2140, 3140 is made of synthetic resin, that is, in a manner in which the film 2140b, 3140b is arranged in a mold and made integral with the door lid 2140, 3140. The transfer method is method of fixing the film 2140b, 3140b on the door cover 2140, 3140, made of glass or synthetic resin by heat bonding with the pressing.

At the same time, to position the touch screen 12 on the door 10, the tactile sensor 160 and the display unit 130 must be combined with the second transparent area 142 of the door cover 140. At the same time, in a design in which the tactile sensor 160 is not located on the display unit 130, it is made separate from the display unit 130 with the possibility of fixing on the rear surface of the door cover 140, the tactile sensor 160 must be fixed in the exact position on the door cover 140 to ensure the reliability of the touch screen 12.

Therefore, it may be important to align the tactile sensor 160 with the second transparent area 142 and the display unit 130. Among other things, during the assembly process, the tactile sensor 160 must be secured in a predetermined position on the door lid 140 to ensure alignment with the display unit 130, which should be assembled with it at the end.

A description will be given below of the connecting structure of the tactile sensor relative to the door cover 140 with regard to such a combination.

FIG. 10 is a conceptual view of the split position between the door lid 140 and the tactile sensor 160 in part C, shown in figure 5, and FIG. 11 is an enlarged view of part C, shown in figure 5.

As shown in FIGS. 10 and 11, an alignment mark 163 may be formed on the tactile sensor 160, and a guide mark 144 for directing the attachment position of the tactile sensor 160 using the alignment mark 163, may be formed on the door cover 140. The alignment mark 163 and the guide The label 144 can facilitate the positioning of the attachment of the tactile sensor 160 relative to the door cover 140.

The tactile sensor 160 may be made in a circular shape (ideal circle, oval, etc.), as well as in a polygonal shape (rectangular shape, hexagonal shape, etc.). However, given that the tactile sensor 160 is a component for implementing the display section 12 in the form of a touch screen, the tactile sensor 160 may preferably be formed in the form corresponding to the display unit 130. 10 and 11, for example, it is shown that the tactile sensor 160 has a rectangular shape corresponding to a rectangular display unit 130.

The tactile sensor 160 may have a larger size than the second transparent area 142 to close the second transparent area 142 formed on the door cover 140. Therefore, a portion of the tactile sensor 160 may be located to close the second transparent area 142. And its other part may be located for closing the opaque region 143 around the second transparent region 142. On another part of the tactile sensor 160, which covers the opaque region 143, an alignment mark 163, which is the reference point for combining the tactile sensor 160 relative to the door cover 140.

Label 163 alignment can be performed in a variety and is located at at least three points of the tactile sensor 160 at a distance from each other. When the alignment mark 163 includes the first alignment mark 163a, the second alignment mark 163b and the third alignment mark 163c, the first virtual alignment line 164 'connecting the first alignment mark 163a and the second alignment mark 163b may intersect with the second virtual alignment line 164ʺ connecting the first alignment mark 163a and the third alignment mark 163c.

An alignment mark 163 may be formed in the corner portion of the tactile sensor 160, which does not correspond to the second transparent area 142. In FIG. 10, for example, it is shown that the first to third alignment marks 163a, 163b and 163c are located on each corner portion of the tactile sensor 160, and The first and second virtual alignment lines 164 'and 164ʺ are located perpendicular to each other.

The guide mark 144 may be formed in the opaque region 143 of the door cover 140 and include a transparent portion 144 '(see FIG. 12) for visual difference in the opaque region 143. The guide mark 144 may be formed in a plurality, located in a plurality of points around the second transparent area 142.

The guide mark 144 may be adapted to conform to the alignment mark 163. The guide mark 144 may be formed in a plurality, located at at least three points of the door cover 140 at a distance from each other. When guide mark 144 includes a first guide mark 144a, a second guide mark 144b and a third guide mark 144c, the first virtual guide line 145 'connecting the first guide mark 144a and the second guide mark 144b may intersect with the second virtual guide line 145ʺ connecting the first guide mark 144a and the second guide mark 144c.

In the case of this design, the tactile sensor 160 can be more accurately combined with the door cover 140 and can also be more accurately combined with the display unit 130, which should be assembled at the end, thus ensuring the reliability of the touch screen 12.

The guide mark 144 may be formed in the opaque region 143 surrounding the second transparent region 142. Figure 10, for example, shows that the first to third guide marks 144a, 144b, and 144c are located in the opaque region 143 around the second transparent region 142, and the first virtual region guideline 145 'and the second virtual guideline 145ʺ are perpendicular to each other.

When the first to third alignment marks 163a, 163b, and 163c are adapted to correspond to the first to third guiding marks 144a, 144b, and 144c, respectively, the tactile sensor 160 may be in the aligned position with the door cover 140. When the tactile sensor 160 is mounted on the back surface of the door the cover 140, the alignment mark 163 may be located in the guide mark 144 with the possibility of overlap.

Moreover, since the guide mark 144 has a transparent portion 144 'for visual difference in the opaque region 143, at least part of the transparent portion 144' may not be closed even if the tactile sensor 160 is mounted on the door cover 140, which may provide a visual difference for the user, at least part of the transparent portion 144 '. This, however, may interfere with the implementation of the simple appearance of the door.

To solve this, in a position in which the front surface of the tactile sensor 160 is fixed to the rear surface of the door cover 140, the security element 180, which is opaque, may be fixed to the rear surface of the tactile sensor 160 to close the guide mark 144. The security member 180 may preferably have the same color tone as the color of the opaque portion 143. The security element 180 may be in the form of a film or a thin strip.

Thus, the security element 180 can be configured to close the transparent portion 144 'of the guide mark 144, which can make it difficult for the user to determine the guide mark 144.

Below will be described the design for alignment between the door cover 140 and the tactile sensor 160 in accordance with the shape of the guide marks 144.

FIG. 12 is a conceptual view of the first exemplary embodiment of the construction for alignment between the tactile sensor 160 and the door cover 140 shown in FIG. 11.

As shown in FIG. 12, the guide mark 144 may include a transparent portion 144 'and an opaque portion 144 ʺ inside the transparent portion 144'.

The transparent portion 144 'may surround the opaque portion 144ʺ with the possibility of separating the opaque portion 144ʺ and the opaque region 143. That is, the clear portion 144' may be formed inside the opaque portion 143, and the opaque portion 144ʺ may be formed inside the clear portion 144 '.

In this drawing, for example, it is shown that the transparent portion 144 'is formed in the form of a closed loop, completely surrounding the opaque portion 144ʺ. However, this embodiment may not be limited to this. The 144ʺ transparent portion may be formed in the form of an open loop surrounding a portion of the 144ʺ opaque portion.

The 144роз opaque region may be formed from the same material as the opaque region 143. In addition, the 144 неп opaque region and the opaque region 143 may have the same color tone (for example, black).

The transparent portion 144 'may be a portion that is removed when the opaque region 143 is formed. For example, the clear portion 144' may be the portion that is removed when printing an opaque material to form the opaque region 143 on the back surface of the door cover 140 (see description regarding a protective layer 140b (FIG. 6)), that is, a portion in which only the transparent cover body 140a is left.

Thus, when the guide mark 144 includes the transparent portion 144 'and the opaque portion 144ʺ inside the transparent portion 144', the user can hardly determine the guide mark 144 due to the formation of the opaque portion 144ʺ inside the transparent portion 144 ', even if the guide mark 144 is formed as a separate component in the opaque region 143 due to the transparent portion 144 '.

When the alignment mark 163 is located inside the opaque portion 144ʺ, the tactile sensor 160 may be aligned with the door cover 140. That is, in a position in which the front surface of the tactile sensor 160 is fixed to the back surface of the door cover 140, the alignment mark 163 may be located inside the opaque section 144ʺ with the possibility of overlap.

The alignment mark 163 may have a color tone that is different from the opaque portion 144. Accordingly, the alignment mark 163 superimposed within the 144роз opaque portion can be easily identified, which can lead to increased convenience in the assembly process.

At the same time, in a position in which the tactile sensor 160 was mounted on the door cover 140, an opaque security element 180 can be fixed on the back surface of the tactile sensor 160 with the possibility of closing the transparent section 144 'of the guide mark 144. The security element 180 can be configured to closing both the transparent portion 144 'and the opaque portion 144ʺ or is formed in the shape of a loop corresponding to the transparent portion 144'.

FIG. 13 is a conceptual view of a second embodiment of a construction for alignment between a tactile sensor 160 and a door cover 140 shown in FIG. 11.

As shown in FIG. 13, the guiding mark 144 can be made entirely in the form of a transparent portion 4144 ′, which differs from the opaque region 4143.

The transparent portion 4144 'may be a portion that is removed when an opaque region 4143 is formed. For example, the transparent portion 4144' may be a portion that is removed when printing an opaque material to form an opaque region 4143 on the back surface of the door cover 140 (see the description regarding protective a layer 140b (FIG. 6)), that is, a portion in which only the transparent cover body 140a is left.

When the alignment mark 4163 is located inside the transparent portion 4144 ', the tactile sensor 4160 can be aligned with the door cover 4140. That is, when the front surface of the tactile sensor 4160 is mounted on the back surface of the door cover 4140, the alignment mark 4163 can be located inside the transparent portion 4144' with the possibility of overlap.

Since the guide mark 4144 corresponds to the entire transparent portion 4144 '. The alignment mark 4163, which is located within the transparent portion 4144 ′ with the possibility of overlap, can be opened out through the transparent door lid 4140. In this construction, the alignment mark 4163 may have the same color tone as the opaque area 4143, so that it is difficult for the user to identify the mark 4163 alignment.

Thus, when the guiding mark 4144 is completely formed as a transparent portion 4144 ′, the size of the guiding mark 4144 can be more reduced than the size in the aforementioned first embodiment, further including an opaque portion 4144. In addition, since the alignment mark 4163 is aligned within the transparent portion 4144 'with the possibility of overlap, the alignment can be more eased than with the first embodiment of the alignment of the alignment mark 4163 within the opaque portion 4144ʺ with the possibility of overlap.

In this case, when the tactile sensor 4160 is mounted on the door cover 4140, the opaque security element 4180 can be fixed on the back surface of the tactile sensor 160 to close the transparent portion 4144 'of the guide mark 4144.

The detailed construction of the tactile sensor 160 relative to the alignment mark 163 will be described below.

Fig.14 is a front view of the tactile sensor 160 shown in Fig.11.

As shown in FIG. 14, the tactile sensor 160 may include a sensory area 160 ', defining a sensory input applied on the door cover 140, and a second transparent region 142 may be superimposed within the sensory area 160'.

In addition, to determine the sensory input used in the opaque region 143 around the second transparent region 142, the sensory region 160 'can be configured to overlap even the opaque region 143 around the second transparent region 142.

The alignment mark 163 formed on the tactile sensor 160 may be located in an area where the sensor region 160 'is not formed. 14, for example, it is shown that the alignment mark 163 is formed in the angular portion of the tactile sensor 160.

The tactile sensor 160 may comprise a flexible printed circuit board (FPCB) 161, which serves as a channel for transmitting the input signal received by the tactile sensor 160 to the control unit. FPCB 161 may have a shape extending from one side of the tactile sensor film 162.

Below will be described the layered design of the tactile sensor 160.

FIG. 15 is a sectional view of the first exemplary embodiment of the tactile sensor 160 along line D-D ′ shown in FIG.

As shown in FIG. 15, the tactile sensor 160 may include a base 162a, a sensory pattern 162b, and a label 162c.

The base 162a may form the appearance of the tactile sensor 160 and be made of an insulating material. The base 162a may be made of a transparent material, so that the visual information displayed on the display unit 130 can be transmitted through it.

The sensory pattern 162b forming the sensory input area 160 ′ of the sensory input can be formed from the base 162a. The touch pattern 162b can be made in a manner in which the metallic elements extend in the first direction (x-axis) and the second direction (y-axis), respectively, to form a mesh pattern. The metal element may be made of a metallic material such as silver (Ag), copper (Cu), gold (Au), and the like.

The metallic material forming the sensory pattern 162b may have a narrow line width (t1, t2) (nanoscale). Therefore, the touch pattern 162b cannot be visually determined by the user and does not interfere with the visual information displayed by the display unit 130.

Metallic materials passing in the first direction and the second direction can be isolated from each other in the overlapped area. For this purpose, the insulating layer may be located on the overlapped portion.

The touchscreen pattern 162b can be electrically connected to FPCB 161 directly or indirectly (via a separate section for signal transmission).

The label 162c forming the alignment mark 163 (163a, 163b) may be formed on the base 162a. The label 162c may be formed from the same material as the sensor pattern 162b and electrically separated from the sensor circuit 162b.

To accomplish this, the label 162c and the sensory pattern 162b can be formed during the same process, rather than using separate processes from each other. For example, the metallic material deposited on the base 162a can be divided into a sensory pattern 162b and a label 162c by applying a masking layer, etching, and the like. In this case, the label 162c may be electrically separated from the sensor pattern 162b with the aid of the etched portion 162d.

That is, the label 162c may be formed from the same metallic material as the sensory pattern 162b, but must be understood as a false region that is electrically separated from the label 162c and thus cannot determine the sensory input. In the case of this design, the label 162c can be made with the possibility of forming the same layer with the sensory pattern 162b on the base 162a.

The label 162c can have a pattern with a given area and is made with the possibility of visual determination by the user, in contrast to the metal element forming the sensory pattern 162b. The label 162c may have an opacity, and as mentioned above, may have a color tone different from the opaque portion 144ʺ (the first embodiment relating to FIG. 12) or have the same color tone as the opaque region 4143 (the second embodiment relating to FIG. 13).

This design may have the advantage of creating a simple layered construction in terms of forming a sensory pattern 162b and a label 162c using a single metallic material. In addition, the design can use a cheap metal material and, thus, have the advantage of replacing the indium-tin oxide transparent electrode containing indium, which is an expensive rare metal called a rare-earth metal.

FIG. 16 is a sectional view of a second exemplary embodiment of a tactile sensor 5160 along line D-D ′ shown in FIG.

As shown in FIG. 16, a tactile sensor 5160 may include a base 5162a, a touch pattern 5162b, a portion 5162e for transmitting a signal, and a tag 5162c.

The base 5162a can form the appearance of the tactile sensor 5160 and be made of an insulating material. The base 5162a can be made of a transparent material, so that the visual information displayed on the display unit 130 can be transmitted through it.

The sensory pattern 5162b forming the sensory input area 5160 'of the sensory input can be formed on the base 5162a. The touchscreen pattern 5162b can be made by a method of depositing a transparent conductive film, such as an indium and tin oxide film (ITO), a carbon nanotube film (CNT), and the like, onto the base 5162a.

The touchscreen pattern 5162b may include first and second patterned layers that extend in the first direction (x-axis) and second direction (y-axis), respectively, to form sensory channels. In this drawing, for understanding the entity, a layer of a sensory pattern is shown for easily describing the connection between the sensory pattern 5162b and the signal transfer portion 5162e.

The touch pattern 5162b can be connected to the signal transfer section 5162e, and the signal transfer section 5162e can be connected to the FPCB 5161. That is, the signal transfer section 5162e can electrically connect the touch drawing 5162b to the FPCB 5161 to transfer the touch input signal, which defined by touch pattern 5162b. The signal transmission portion 5162e may be made of colored material, but may not be opened to the outside as a result of closing the door cover 5140 by the opaque region 5143.

Label 5162c, forming labels 5163a and 5163b, can be formed on the basis of 5162a. The label 5162c may be electrically separated from the sensor pattern 5162b and the signal section 5162e. Label 5162c can be formed in the form of a pattern with a given area, and, thus, visually determined by the user, in contrast to the touch pattern 5162b.

The label 5162c may be opaque and, as mentioned above, may have a color tone different from the opaque portion 144ʺ (first embodiment, referring to FIG. 12) or have the same color tone as the color tone of the opaque region 4143 (second embodiment related to FIG. 13).

The label 5162c may be made of the same material as the signal transmission section 5162e, but electrically separated from the signal transmission section 5162e. To accomplish this, a 5162c tag and a 5162e signal transmission section can be formed during the same process, rather than using separate processes. For example, the metallic material deposited on the base 5162a can be divided into a signal transmission section 5162e and a label 5162c through processes such as applying a masking layer, etching, and the like. In this case, the label 5162c may be electrically separated from the section 5162e for transmitting the signal using the etched section 5162d.

The label 5162c may be made of a material different from the material of the signal transfer section 5162e, and is formed by different processes. In this case, a tactile sensor 5160 with alignment marks 5162a and 5163b can be manufactured using a simple process of forming the label 5162c on a prefabricated tactile sensor 5160.

A method for manufacturing a door cover 140 coupled to a tactile sensor 160 will be described below.

FIG. 17 is a flow diagram illustrating a method for connecting the door cover 140 and the tactile sensor 160 shown in FIG. 11, and FIG. 18 is a flow diagram illustrating the detailed step of attaching the tactile sensor 160 to the door cover 140 in the structure shown in Fig. 12.

As shown in FIG. 17, for the manufacture of the door cover 140, an opaque area 143 surrounding the second transparent area 142 may be formed on one surface of the door cover 140, which is made of a transparent material (S10). As mentioned above, to form the second transparent area 142 and the opaque area 143 on the door cover 140, the opaque material can be printed on one surface of the door cover 140, or a film with an opaque portion 144 ʺ on it can be fixed on one surface of the door cover 140.

Then, the tactile sensor 160, which determines the sensory input used in the second transparent area 142, can be attached to one surface of the door cover 140 (S30). The step of fixing the tactile sensor 160 may include aligning the alignment mark 163 of the tactile sensor 160 to overlap the guide mark 144 formed in the opaque region 143.

In this regard, in the first embodiment depicted in FIG. 12, the alignment mark 163 may be aligned within the guide mark 144 using the special steps below.

As shown in FIG. 18, the tactile sensor 160 may be combined in a manner in which the alignment mark 163 is located inside the transparent portion 144 'of the guide mark 144 (S31). After that, the location of the tactile sensor 160 can be adjusted so that the alignment mark 163 is located on the opaque portion 144 образов formed inside the transparent portion 144 ′ (S32). In this case, the location of the tactile sensor 160 can be finely adjusted, so that the aforementioned first to third marks 163a, 163b, and 163c are located within the opaque portion 144ʺ of the first to third guide marks 144a, 144b, and 144c, respectively.

The combination can be done by adjusting the location of the tactile sensor 160, while the user checks this visually, either using the device, or in a fully automatic way using the device.

After attaching the tactile sensor 160 to the door cover 140, the opaque security element 180 can be attached to the tactile sensor 160 to close the guide mark 144 (S40). The display unit 130 may then be located to close the second transparent area 142 of the door 10, thus fully producing the touch screen 12.

In this case, the door cover 140 may have at least a portion formed in a curved shape. For this purpose, after forming the opaque region 143 and before fixing the tactile sensor 160 on the door cover 140, a modification of the door cover 140 may be added to the bent shape by pressing the door cover 140 (S20).

FIG. 19 is a sectional view along line E-E 'shown in FIG. 4. FIG.

As shown in FIG. 19, the door cover 140 may be connected to the door frame 110. As mentioned above, the door frame 110 may include an outer frame 111 and an inner frame 112.

The outer frame 111 can be designed in such a way that the door cover 140 is fixed to the front surface of the outer frame 111. The inner frame 112 can be connected to the back side of the outer frame 111. The connection between the outer frame 111 and the inner frame 112 can be made through a screw connection, crochet joints, bonding joints or the like.

This drawing shows the connected structure between the outer frame 111 and the inner frame 112 by means of gluing. In detail, the connecting rib 112d may protrude from the inner frame 112, and the rib section 111e for accommodating the rib on which the connecting edge 112d is disposed may protrude from the rear surface of the outer frame 111, and the adhesive member 172 can be filled in the rib section 111e.

In this case, when the outer frame 111 and the inner frame 112 are connected to each other, the outer peripheral portion of the inner frame 112 may protrude on the front surface of the outer frame 111, thus forming the support guide 112c. The anchor rail 112c may extend in the form of a loop along the periphery of the outer frame 111 to form a region in which the door cover 140 is placed.

The support rail 112c may be positioned to close the side surface of the door cover 140 and protrude to a predetermined height so that the upper surface of the support rail 112c may be flush with the upper surface of the adjacent door cover 140. In this design, the step between the support rail 112c and the door the cap 140 can be reduced, thus providing a more simplified appearance.

FIG. 20 is a conceptual view of the door cover 140 and the door frame 110 in a separated position in the part F shown in FIG. 4.

Basically, areas with certain shapes (for example, vertex (corner) areas, recessed areas, etc.) can serve as reference points for fixing (aligning) the installation location during the assembly process to facilitate the assembly process. However, as shown in this embodiment, in the case in which the door lid 140 is formed in a circular shape, since the edge of the door lid 140 is rounded, it is not easy to find an appropriate portion for fixing (aligning) the installation location during the assembly process. Specifically, in the present invention, if the door cover 140 is not connected at the exact position on the door frame 110, the first and second transparent areas 141 and 142 of the door cover 140 may not correspond to the first and second openings 110a and 111b of the door frame 110 or may not be aligned with the first and second openings 110a and 111b of the door frame 110.

To solve this problem, as shown in FIG. 20, the door lid 140 may include a support portion (set point) for aligning the installation position in the assembly with the door frame 110.

In detail, the door lid 140 may include a first edge 140 ', rounded into a circular shape, and a second edge 140 linearly connecting both sides of the first edge 140'. That is, the door cover 140 may have a circular shape with a portion cut into a linear shape.

The aforementioned support guide 112c may include a first protruding portion 112 ', extending in a rounded shape, to match the first edge 140', and a second protruding portion 112cʺ, extending in a linear form, to match the second edge 140ʺ.

In accordance with this design, the second edge 140ʺ and the second protruding portion 112cʺ can become set points for adjusting the mounting positions of the door cover 140 and the door frame 110 when assembled with each other. That is, when the second edge 140ʺ is positioned to correspond to the second protruding section 112cʺ, the door cover 140 may be located in a fixed position on the door frame 110. This may ensure that the first and second transparent areas 141, 142 of the door cover 140 are aligned with the first and second openings 110a , 111b door frame 110.

In addition, since the door cover 140 is located in a fixed position on the door frame 110, a tactile sensor 160 mounted on the door cover and the display unit 130 connected to the door frame 110 can be aligned with each other. This can lead to ensuring the reliability of the touch screen 12.

The second protruding section 112cʺ may be located at any position on the door frame 110. However, the second protruding section 112cʺ may preferably be formed on the underside of the door frame 110, so that the user cannot easily determine that the door 10 has a round shape with a partially cut out section .

In this case, as shown in FIG. 20 and FIG. 19, the door cover 140 can be connected to the door frame 110 using liquid sealing material 171. A groove 111d for filling the sealing material into which the sealing material 171 is filled can be formed on the front surface of the outer frame 111.

The groove 111d for filling the sealing material may include a section 111d ′ filled with a sealing material and areas 111dʺ for collecting the sealing material.

Section 111d ', filled with sealing material, which is the area for filling the sealing material 171, may surround the first hole 110a and the second hole 111b.

Sections 111dʺ for collecting sealing material for collecting sealing material 171 extending to the inner and outer sides of the section 111dʺ for applying a sealing material can be formed on both sides of the section 111d ′ filled with sealing material, respectively. The sections 111dʺ for collecting the sealing material may run parallel to the section 111d ′ filled with sealing material, at a predetermined distance from the section 111d ′ filled with sealing material. Sections 111dʺ for collecting sealing material may have a smaller width compared with section 111d ', filled with sealing material.

The protrusions 111f may protrude between the region 111d ′ filled with sealing material and the regions 111dʺ for collecting the sealing material to a predetermined height. The protrusions 111f may protrude to a height corresponding to the front surface of the outer frame 111. In this case, the protrusions 111f may function as supporting surfaces for supporting the door cover 140.

In this design, even if the sealing material 171 filled in the portions 111d ′ filled with the sealing material flows during the process of connecting the door cover 140 to the outer frame 111, the leaking sealing material 171 can be assembled in the portions 111dʺ to collect the sealing material formed on the inner and outer sides of the portion 111d ′ filled with sealing material, respectively. This can lead to the prevention of deterioration of the appearance due to leaked sealing material.

In addition, in accordance with this design, the portion 111d 'filled with sealing material can be located as close as possible to the edge of the outer frame 111. Therefore, the unconnected edge portion of the door cover 140 can be minimized, which can lead to an increase in adhesion strength and effective prevention penetration of foreign materials through the gap between the door cover 140 and the outer frame 111.

Fig.21-24 - conceptual views of options for the design of the location of the tactile sensor relative to the door cover.

These options have the same problems to be solved as the above constructions. That is, the structure and method, which will be explained below, are intended to create a positioning arrangement between the door lid 140 and the tactile sensor 160 for realizing the display portion 12 as a touch screen when forming the window 11, through which the laundry load hole 20a is visible, and the portion 12 displays information processed in the laundry treating device 1. In addition, the structure and method, which will be explained below, are also intended to create a structure in which the components for fixing the tactile sensor 160 in a predetermined position of the door cover 140 cannot be seen from the outside of the door.

First of all, as shown in FIG. 21, the alignment mark 6163 for fixing the tactile sensor 6160 in the correct position in the second transparent area 6142 is formed on the tactile sensor 6160. In contrast to the above embodiments, this embodiment does not use a separate guide mark on the door cover 6140 and the boundary between the second transparent area 6142 and the opaque area 6143 formed on the door lid 6140 serves as a reference point for setting the position of the alignment mark 6163.

That is, the alignment mark 6163 is aligned based on the boundary between the second transparent region 6142 and the opaque region 6143, so that the tactile sensor 6160 can be fixed in the correct position on the door lid 6140. The boundary used for alignment can be the boundary line between the second transparent region 6142 and the opaque region 6143, the angle of the second transparent region 6142, and the like.

In this drawing, for example, it is shown that the tactile sensor 6160 and the second transparent area 6142 have rectangular shapes that correspond to a rectangular display unit.

The tactile sensor 6160 has a size larger than the second transparent area 6142 to close the second transparent area 6142 formed on the door lid 6140. Therefore, a portion of the tactile sensor 6160 is located to close the second transparent area 6142, and the other part of the tactile sensor 6160 is located to close the opaque area 6143 around the second transparent area 6142. A registration mark 6163 may be formed on another part of the tactile sensor 6160, which is located to close the opaque area 6143.

The alignment mark 6163 may be made in various forms, such as a dot, a line, or the like. As shown in this embodiment, when the alignment mark 6163 is made in the form of a dot, the alignment points 6163a and 6163b can be located, in at least two positions, at a distance from each other. The alignment points 6163a and 6163b may be formed in the angular positions of the tactile sensor that do not correspond to the second transparent region 6142. In this drawing, for example, it is shown that the alignment points 6163a and 6163b are indicated in at least two angular positions of the tactile sensor 6160.

Since the alignment points 6163a and 6163b are arranged to correspond to the corners of the second transparent area 6142, the tactile sensor 6160 can be fixed in the correct position on the door lid 6140.

In this document, for example, the alignment points 6163a and 6163b may be positioned to overlap the non-transparent area 6143 bounding the corners. In this case, the alignment points 6163a and 6163b are not open through the second transparent area 6142, which is an advantage in that the security element 6180 is not needed, which will be explained below.

In this case, the alignment points 6163a and 6163b may be formed with a color tone different from the opaque area 6143 for visual difference in the opaque area 6143. For example, when the opaque area 6143 has a black color tone, the alignment points 6163a and 6163b may have a color such as gray, white, yellow except for black color tone.

Here, as another example, the alignment points 6163a and 6163b may be located to overlap the second transparent area 6142, which forms the corners. In this case, the alignment points 6163a and 6163b are open to the outside through the second transparent area 6142, thus reducing attention to appearance.

In order for the alignment points 6163a and 6163b to be invisible, the opaque security elements 6180 can be located to close the tactile sensor 6160 to close the alignment points 6163a and 6163b. The security elements 6180 are positioned to close both the alignment points 6163a and 6163b, and the non-transparent area 6143 near the alignment points 6163a and 6163b.

The security elements 6180 can be formed with the same color tone as the color tone of the registration points 6163a and 6163b, so that the registration points 6163a and 6163b are not visible through them. In addition, the security elements 6180 can be formed with the same color tone as the color tone of the opaque area 6143, to give a sense of how the opaque area 6143 passes.

The security elements 6180 may be located in the second transparent region 6142 to overlap the alignment points 6163a and 6163b. The security elements 6180 may be formed in a shape corresponding to the alignment points 6163a and 6163b, or may extend along at least one side of the second transparent region 6142.

On Fig shown that the label 7163 alignment made in the form of a line. Alignment line 7163 may extend along at least one side of the tactile sensor 7160. Alignment line 7163 may be formed on the edge of the tactile sensor 7160, which does not correspond to the second transparent area 7142. In this drawing, for example, it is shown that alignment line 7163 is shown along the left edge (in the drawing) tactile sensor 7160.

Since the alignment line 7163 is located to correspond to the border 7142 'between the second transparent area 7142 and the opaque area 7143, the tactile sensor 7160 can be fixed in the correct position on the door cover 7140.

For example, as shown in FIG. 23, the alignment line 7163 may be located to overlap the opaque region 7143, which forms the border 7142 'between the second transparent region 7142 and the opaque region 7143. In this case, the alignment line 7163 is not open through the second transparent region 7142, which is an advantage in that the security element 7180 is not needed, which will be explained below.

In this case, the alignment line 7163 may be formed with a color tone different from the opaque area 7143 for visual difference in the opaque area 7143. For example, when the opaque area 7143 has a black color tone, the alignment line 7163 may have a color such as gray, white , yellow except for black color tone.

As another example, as shown in FIG. 24, the alignment line 7163 may be located to overlap the second transparent area 7142, which forms the border 7142 'between the second transparent area 7142 and the opaque area 7143. In this case, the alignment line 7163 is open to the outside through the second transparent area 7142, thus reducing attention to appearance.

In order for the alignment line 7163 to be invisible, the opaque security element 7180 may be located to close the tactile sensor 7160 in order to close the alignment line 7163. The security element 7180 is positioned to close both the alignment line 7163 and the non-transparent area 7143 near the alignment line 7163.

The security element 7180 may be formed with the same color tone as the color tone of the alignment line 7163, so that the alignment line 7163 is not visible through it. In addition, the security element 7180 may be formed with the same color tone as the color tone of the opaque area 7143 to give a sense of how the opaque area 7143 passes.

The security element 7180 may be located within the second transparent region 7142 to overlap the alignment line 7163. The security element 7180 may extend along at least one side of the second transparent region 7142.

In these embodiments, the alignment marks 6163 and 7163 may be formed by the label 162c, 5162c. Therefore, their repeated description will be omitted.
