Description

Washing machine {LAUNDRY MACHINE}

The present invention relates to a laundry machine for processing laundry.

Generally, a washing machine includes a washing machine and a dryer.

The washing machine includes a pulsator-type washing machine and a drum washing machine, and there is also a combined-use washing machine, which may not only perform washing but also drying.

In general, a dryer is a device for drying wet laundry using hot air or the like.

In the drum washing machine, the tub is arranged horizontally, and the drum is also arranged horizontally therein. The laundry is placed inside the drum and tumbled and washed as the drum is pointed.

The tub serves to receive the wash water, and the drum is where the laundry is placed and washing is performed.

The drum is rotatably installed in the tub.

The drum has a rotating shaft connected to the rear, the rotating shaft receives a rotational force from the motor. Thus, the rotational force is transmitted to the drum through the rotation shaft by the rotation of the motor to rotate the drum.

During washing, as well as during rinsing and dehydration, the drum is rotated and the drum vibrates while rotating.

The rotating shaft penetrates the rear wall of the tub and protrudes out of the tub. In a conventional washing machine, a bearing housing is sometimes inserted into an insert molding on a rear wall of a tub. Alternatively, the bearing housing is fastened to the rear wall of the tub.

The rotating shaft is supported by the bearing housing, and the vibration of the drum is transmitted to the bearing housing and the tub through the rotating shaft.

Thus, the tub vibrates with the drum, and a shock absorbing member is connected to the tub to damp the vibration.

That is, the conventional washing machine is a structure in which the vibration of the drum is transmitted to the tub as it is, such a vibration is a structure that is supported through the buffer support member connected to the tub.

It is an object of the present invention to provide a washing apparatus having an increased washing capacity compared with the related art. In particular, it is an object of the present invention to provide a new washing apparatus having increased washing capacity without greatly changing the size of the washing apparatus.

In this case, it may be advantageous to increase the capacity in consideration of interference between the drum and the tub or between the tub and the cabinet. In addition, it may be advantageous to increase the capacity in view of the assembly viewpoint.

Washing apparatus according to the present invention may include a suspension assembly connected to the driving unit for buffering the vibration of the drum. Conventionally, the suspension assembly is connected to the tub to buffer the vibration of the tub and drum together, but the washing apparatus according to the present invention may have a structure in which the vibration of the drum and the tub are separated. The tub may be supported more rigidly than the drum is supported by the suspension assembly.

A further example of the tub being supported by a more rigid structure than the suspension assembly is shown below.

First, the tub may be formed integrally with at least a part of the cabinet.

Second, it may be connected and supported by screws, rivets, rubber bushings, or the like, or may be fixed and supported by welding, adhesive sealing, or the like. In this case, such a connecting member has a rigidity higher than that of the suspension assembly with respect to the vertical direction, which is the main vibration direction of the drum.

On the other hand, a flexible member may be included to reduce the transmission of vibration of the drum to the tub. The flexible member can be made to flexibly connect the tub and the drive to prevent leakage of the drive and the tub and to allow the drive to move relative to the tub. Such a flexible member may be made of a rear gasket.

In one embodiment of the present invention, the tub may be extended so that the distance between the cabinet light or the cabinet left of the cabinet is 10 mm or less.

Another embodiment may be a laundry machine in which the outer diameter of the drum is a difference of less than or equal to 100mm in the left and right inner width of the cabinet.

In addition, in another embodiment, the tub may have a smaller horizontal space with the cabinet than the horizontal space with the drum when the tub is based on the center of the drum. The tub may be installed so as not to contact the cabinet left or the cabinet light of the cabinet.

The above-described embodiments can be combined in various forms within the scope of not contradicting each other to give another embodiment.

Washing apparatus according to the present invention can increase the washing capacity without changing the size of the appearance significantly compared to the conventional.

Figure 1 shows a partially exploded perspective view of an embodiment of a washing machine of the present invention.

The tub is fixedly supported by the tub in the cabinet. The tub includes a tub front 100 constituting the front portion and a tubere 120 constituting the rear portion. The tub front 100 and the tubular 120 are assembled by screws, and form a space in which a drum is accommodated. The tubular 120 has an opening in the rear surface. The inner circumference of the rear of the tubular 120 is connected to the outer circumference of the rear gasket 250. The inner circumference of the rear gasket 250 is connected to the tub back 130. The tub back 130 has a through hole through which a rotating shaft passes. The rear gasket 250 is made of a flexible material so that the vibration of the tubback 130 is not transmitted to the tubular 120.

The rear gasket 250 is connected to the tub back 130 and the tubular 120 so as to be respectively sealed so that the wash water in the tub does not leak. The tubback 130 vibrates with the drum when the drum rotates, and is spaced apart from the tubular 120 at a sufficient interval so as not to interfere with the tubular 120. Since the rear gasket 250 is made of a flexible material, the tubback 130 allows relative movement without interfering with the tubular 120. The back gasket 250 may have a pleat that may extend to a sufficient length to allow such relative movement of the tubback 130.

The front portion of the tub front 100 is connected to the foreign matter prevention member 200 for preventing foreign matter from flowing between the tub and the drum. The foreign matter pinching member 200 is made of a flexible material, it is fixed to the tub front (100). The foreign matter prevention member 200 may be made of the same material as the rear gasket 250.

The drum is composed of a drum front 300, a drum center 320, a drum bag 340 and the like. In addition, ball balancers 310 and 330 are installed at the front and rear portions of the drum, respectively. The drum bag 340 is connected to the spider 350, the spider 350 is connected to the rotating shaft 351. The drum is rotated in the tub by the rotational force transmitted through the rotating shaft 351.

The rotary shaft 351 is directly connected to the motor through the tub back 130. Specifically, the rotor of the motor (not shown) and the rotation shaft 351 are directly connected. The bearing housing 400 is coupled to the rear surface of the tub bag 130. The bearing housing 400 rotatably supports the rotation shaft 351 between the motor and the tub back 130.

The stator of the motor is fixed to the bearing housing 400. Then, the rotor surrounds the stator. The motor is an outer rotor type motor that is directly connected to the rotating shaft 351.

The bearing housing 400 is supported from the cabinet base 600 through the suspension assembly. The suspension assembly includes three vertical supports and two inclined supports that are inclined with respect to the front and rear directions. The suspension assembly is connected to the cabinet base 600 to allow some elastic deformation. That is, the suspension assembly is elastically supported to allow some degree of rotation in front and rear and left and right with respect to its support point connected to the base. The vertically installed suspension for such elastic support may be installed in the base 600 via a rubber bushing. The vertical installation of the suspension can be configured to elastically dampen the vibration of the drum and the tilted installation can be configured to damp the vibration. That is, in the vibration system including the spring and the damping means, the vertical installation may serve as a spring and the tilted installation may serve as a damping means. In this case, the three vertical supports are springs or spring dampers (dampers that function as springs and damping), and the two inclined supports are simple dampers (dampers that do not merely act as springs but merely damping functions). However, in other embodiments, the slope may also be made of a spring damper.

2 shows a state in which a suspension assembly is assembled to a bearing housing 400 and mounted on a base 600. The suspension assembly is connected to the bearing housing 400 to reduce the vibration of the drum.

The suspension assembly may include brackets connecting the bearing housing 400 and the suspensions. The brackets include a radial bracket connected to the bearing housing 400 to extend radially and an axial bracket connected to the radial bracket and extended forward.

The radial bracket includes a first radial bracket 431 and a second radial bracket 430 disposed symmetrically with each other.

The first radial bracket 431 and the second radial bracket 430 serve to connect the first axial bracket 450 and the second axial bracket 440 to the bearing housing 400, respectively. .

The suspension assembly may include a vertical suspension for cushioning in the vertical direction and a front and rear suspension for cushioning in the front and rear directions. The vertical suspension may be disposed at one rear and two left and right at the front of the base center. In addition, two suspensions may be installed by inclining in the front-rear direction at both left and right sides.

Specifically, in the present embodiment, as shown in FIG. 2, the suspension assembly includes a first cylinder spring 520, a second cylinder spring 510, a third cylinder spring 500, a first cylinder damper 540, and a second cylinder. Cylinder damper 530 is included.

The cylinder spring is a spring is installed between the cylinder and the piston. Since it is in the form of a cylinder and a piston, the length is stably changed when fully charged. The cylinder is connected to the axial bracket and the piston is connected to the base side.

The cylinder damper has a structure in which the piston moves in the cylinder to obtain a damping effect by frictional resistance.

The first cylinder spring 520 is connected between the first axial bracket 450 and the base 600. In addition, the second cylinder spring 510 is connected between the second axial bracket 440 and the base 600.

The third cylinder spring 500 is directly connected between the bearing housing 400 and the base 600.

The first cylinder damper 540 is inclined between the first axial bracket 450 and the base rear portion, and the second cylinder damper 530 is between the second axial bracket 440 and the base rear portion. It is installed inclined at.

The third cylinder spring is disposed at the center of the rear, and the first cylinder spring and the second cylinder spring are disposed at the front left and right. Then, the first cylinder damper and the second cylinder damper are positioned between the rear point of the third cylinder spring and the front point of the first cylinder spring and the second cylinder spring. And they are symmetrical.

The cylinder springs are connected to the base 600 via a rubber bushing.

On the other hand, the cylinder spring may be made to exert a damping force. In this case, the cylinder spring is a spring damper. The cylinder damper may also be provided with a spring. In this case, the cylinder damper is no longer a simple damper but a spring damper.

In this embodiment, the tub is fixedly installed in the cabinet, the vibration of the drum is buffered by the suspension assembly. Substantially, the tub and the support structure of the drum may be referred to as a separate form, and the tub may be referred to as a form that does not vibrate even if the drum vibrates. Specifically, the tub may be seated so as to be independent of the base 600 of the cabinet, and the front surface may be connected to the cabinet front (not shown), and the rear surface may be fixed to the cabinet rare 620.

3 and 4 shows the tub front 100, the tubular 120, the tub back 130, the rear gasket 250 is coupled.

The tub front 100 is fixedly connected to the cabinet front as described above. The fastening boss is formed on the front portion of the tub front 100 so as to substantially surround the laundry entrance opening for the fixed connection. In the state where the tub front 100 is installed, the cabinet front is positioned and then fastened by tightening screws from the front to the rear.

The lower portion of the tub front 100 is formed with a base coupling for fixing to the base 600. The base coupling part includes a first hollow coupling part 108a and a second hollow coupling part 108b that are hollow cylindrically shaped. And, it includes a first screw fastening portion 109 for screwing. After the tub front 100 is positioned on the base 600, the screw is fastened to the first screw fastening portion 109 from the front to the rear to be fixed.

Tubular 120 is formed in a cylindrical shape surrounding the drum, the front is open as it is, the rear portion has a donut-shaped rear surface 128. The front part is sealingly coupled with the tub front 100. The diameter of the rear surface 128 of the tubular 120 is sufficiently larger than the outer diameter of the tubback 130. Even if the tubback 130 vibrates, the tubback 130 may have an interval that does not interfere with the rear surface 128 of the tubere 120. In addition, the rear gasket 250 is connected between the gap, that is, the rear surface 128 and the tub back 130. The rear gasket 250 seals the tub back 120 and the tub back 130. The rear gasket 250 may have a pleated portion that is sufficiently flexible so that the vibration of the tubback 130 is not transmitted to the tubular 120.

The tubular 120 is provided with a coupling portion 123 for coupling to the cabinet rare 620.

In addition, the tubular 120 is fixed to the cabinet base 600. For this purpose, the third hollow coupling part 125a and the fourth hollow coupling part 125b and the second screw fastening part 126 are disposed at the bottom thereof. ) Is formed. The screw fastening portion is in the form of tightening the screw from the rear to the front in the state joined to the base.

The second screw fastening portion 126 is alternately disposed without being located on the same line with respect to the front-rear direction of the first screw fastening portion 109 formed in the tub front 100. When looking forward from the rear, the first screw fastening portion 109 is disposed on the right side and the second screw fastening portion 126 is disposed on the left side.

The base coupling portions are provided in the tub front 100 and the tubular 120, respectively, for the purpose of compatibility of the tubular 120. Depending on the capacity of the washing machine, the tub front 100 uses the same structure, but the tubere 120 can be used interchangeably with different lengths. At this time, since the tub front 120 needs to be replaced or replaced in the state in which the tub front 100 is mounted on the base 600, the tub front 100 and the tubular 120 have base coupling parts, respectively. It may be desirable.

The tub is mounted on the tub support front 50 and the tub support rare 55 will be described in detail with reference to FIGS. 3, 4 and 5. First, the first rubber bushing 51 of the tub support front 50 is formed in the first hollow coupling part 108a of the tub front 100, and the first rubber bushing 51 of the tub support front 50 is formed in the second hollow coupling part 108b. Two rubber bushings 52 are inserted. The screw fastening portion 109 of the tub front 100 is seated on the screw fastening portion 53 on the right side of the screw fastening portions 53 and 58 of the tub support front 50 and screwed thereto. At this time, the screw tightening direction is from front to rear.

The third rubber bushing 56 of the tub support rare 55 is disposed in the third hollow coupling portion 125a of the tubular 120, and the fourth rubber bushing 56 of the tubular 120 is disposed in the fourth hollow coupling portion 125b. The rubber bushing 57 is inserted. Then, the screw fastening portion 126 of the tubular 120 is seated and screwed to the screw fastening portion 58 on the left side of the screw fastening portion of the tub support rare 55. Here, the direction of tightening the screw is from rear to front.

In the washing apparatus of the present embodiment, since the vibration of the tub is remarkably small, the gap of the tub does not need to be maintained due to the vibration, so the outer surface of the tub may be located as close as possible to the cabinet. And, this makes it possible to expand the size of the tub even if the size of the cabinet is not increased, resulting in an increase in the capacity of the washing apparatus in the size of the same appearance. Substantially, the distance between the cabinet light 630 or the cabinet left 640 and the tub may be reduced to 10 mm or less. In the present embodiment, the distance between the outer peripheral surface of the tub and the cabinet is about 5 mm, and in this case, considering the rib formed on the outer peripheral surface of the tub, the interval between the rib and the cabinet is about 3 mm. In the conventional tub washing machine vibrating together was about 30mm at intervals so that the vibration of the tub does not interfere with the cabinet. Considering the diameter of the tub, the washing apparatus of the present embodiment can extend the diameter of the tub by approximately 50 mm more than the conventional one. As the size of the tub is expanded in this way, the volume of the drum installed therein can be greatly expanded. Compared with the conventional washing machine, even if the same external size, the washing capacity can be obtained by one step.

On the other hand, even if the size of the tub is not in contact with the cabinet light 630 or the cabinet left 640 may be advantageous for assembly. Determining the size of the tub so that it fits within the cabinet's left and right spacing (the gap between the cabinet lights and the inner surfaces of the cabinet left) can cause interference between the cabinet and the tub, which can be disadvantageous for assembly. In addition, even when considering the interference with the bracket of the suspension assembly, it may be advantageous to extend the tub only to the extent that it does not touch the cabinet light 630 or the cabinet left 640. Thus, the tub may be made to extend to have a distance of 3 ~ 10mm with the cabinet light 630 or the cabinet left 640.

In this case, the diameter of the opening for the laundry in and out of the drum may be substantially the same or larger than the diameter of the opening for the laundry out of the tub. The drum may include a tip portion that forms the opening and extends forward. Here, the leading end of the drum is located further rearward than the opening of the tub. Furthermore, the front end of the drum is located behind the inner wall of the front part of the tub. In this embodiment, the drum is located between the front wall portion and the rear wall portion of the tub.

Hereinafter, the spacing between the drum 300 and the tub will be described with reference to FIG. 6. In the non-load state in which no laundry is put, the interval formed between the front upper portion of the drum and the inner upper surface of the tub is preferably provided to be smaller than the interval formed by the inner lower surface of the front lower portion of the drum and the tub.

That is, the gap G1 formed by the upper outer circumferential surface of the drum and the upper inner circumferential surface of the tub is provided to be smaller than the gap G3 formed by the lower outer circumferential surface of the drum and the lower inner circumferential surface of the tub. This is in consideration of the fact that when the laundry is put into the drum, the drum may be displaced downward.

On the other hand, the interval formed by the rear outer circumferential surface of the drum and the inner circumferential surface of the tub rear portion may also make the upper interval smaller than the lower interval for the same reason as described above.

The interval G2 formed between the front surface of the drum and the front inner surface of the tub is preferably set so as not to interfere with the tub when the drum vibrates back and forth. In particular, the gap G2 may consider a gap with the inner surface of the tub located forward from the outer circumferential front end of the drum front. Here, the interval G2 between the drum and the tub may be an interval in consideration of a balancer mounted on the drumfront (as is the interval described in other parts of the present specification). That is, when the ball balancer is mounted, it may be a distance between the front end of the ball balancer and the inner surface of the tub located in front of the ball balancer.

Therefore, the drum front 320 and the front inner circumferential surface of the tub need to maintain a sufficient distance so that the drum does not interfere with the tub even when the drum vibrates back and forth.

On the other hand, the interval (G4) formed by the drum back 330 and the rear inner peripheral surface of the tub should be provided so as not to interfere with the drum bag 330 or the spider 340 and the rear surface of the tub when the drum rotates.

That is, since the front and rear vibrations may be caused when the drum rotates, G4 should be designed in consideration of this.

In addition, in consideration of the left and right vibration of the drum, the left and right intervals between the outer peripheral surface of the drum and the inner peripheral surface of the tub is set.

Here, the displacement of the drum in the left and right directions is relatively small so that the diameter of the drum can be increased by minimizing the horizontal gap between the drum and the tub. The diameter of the drum is related to the capacity of the washing machine. The larger the diameter of the drum, the larger the internal volume can expand the capacity of the washing machine. In the case where the width in the left-right direction is the smallest among the front-rear width, the horizontal width, the vertical width, and the like of the washing machine, the diameter of the drum may be determined in consideration of the horizontal width. At this time, if the movement in the left and right direction of the drum is minimized, the horizontal gap between the drum and the tub can be minimized, so that the diameter of the drum can be maximized.

That is, the sum G5 + G6 of the gaps in the left and right directions of the drum and tub spacing may be made smaller than the sum of the other gaps G1 + G3 or G2 + G4 to maximize the diameter of the drum as much as possible. In the present embodiment, the drum and the tub have a relationship of the sum of the horizontal gaps G5 + G6 <the sum of the front and rear gaps G2 + G4 <the sum of the vertical gaps G1 + G3.

The aforementioned intervals G1, G2, G3, G4, G5, and G6 may be defined as intervals considering interference between the drum and the tub. Thus, if any part is to be mounted on a tub or drum at its corresponding position to the gaps, the gap must be determined in consideration of that part. The case of the above-described ball balancer may be an example. For convenience, the intervals may be referred to as an interference gap. That is, G1 is the vertical interference interval with the tub for the upper drum front, G2 is the vertical interference interval with the tub for the drum front upper, G3 is the vertical interference interval with the tub for the drum front lower, G4 is the drum rear The front and rear interference intervals with the tub to the lower portion, G5 may be defined as the left and right interference intervals with the tub to the right side of the drum, G6 may be defined as the left and right interference intervals with the tub to the left side of the drum. Here, the left or right refers to the left or the right when looking toward the front from the rear of the washing machine.

In order to minimize the lateral displacement of the drum during vibration, the suspension assembly may be made to have a rigidity for the left and right displacement of the drum greater than the stiffness for the vertical and longitudinal displacement. For this reason, the axial bracket may be designed to have a larger area secondary moment with respect to the lateral axis than the area secondary moment with respect to the vertical axis.

On the other hand, as mentioned above, in order to make the volume of the drum as large as possible, the volume of the tub must also be increased. In particular, the larger the width in the left and right direction of the inner peripheral surface of the tub can increase the diameter of the drum. To this end, the left shaft and the right side of the tub are preferably in contact with the cabinet left and the cabinet light or extend as close as possible. Preferably, with respect to the horizontal horizontal line of the drum center, the difference between the left and right width (distance between the cabinet left and the cabinet light) and the drum outer diameter of the washing machine is 100mm or less so that conventional washing having the same left and right width Compared to the apparatus, the volume of the drum can be expanded to provide a washing apparatus having an increased capacity. The smaller the displacement of the drum in the lateral direction, the larger the diameter of the drum is, which is advantageous for increasing the capacity. However, decreasing the lateral displacement of the drum means that the stiffness of the lateral support of the drum by the suspension assembly is relatively large. If the stiffness is too large, it may be detrimental to the vibration characteristics of the drum. For example, abnormal vibration may occur in a steady state section of about 400 rpm or more when the drum rotates at high speed. In such a view, it may be advantageous to keep the difference between the left and right widths of the washing machine (the distance between the cabinet left and each outer surface of the cabinet light) and the drum outer diameter at 80 mm or more.

As the rotation speed of the drum increases during dehydration, an excessive vibration region may occur in which the vibration amount increases due to resonance, and after the drum rotation speed increases, the vibration amount of the drum becomes constant to a relatively low level after passing the vibration region. This leads to the status area. The abnormal vibration may be a vibration phenomenon in which the vibration amount of the drum increases and decreases in the steady state region or the vibration amount increases ideally.

In addition, the distance between the left or right side of the drum and the tub may be 1.5 times or more the distance between the left or right side of the tub and the cabinet left or cabinet light based on the horizontal horizontal line of the drum center. That is, the diameter of the drum can be expanded as large as possible by reducing the distance between the left or right side of the tub and the cabinet left or cabinet light. As the tub is extended as close as possible to the cabinet to secure the interior space, the diameter of the drum can be extended to provide a washing machine with a much increased capacity even with the same appearance size. However, if the tub is too close to the cabinet light or cabinet left, it may be inconvenient to assemble, and components that should not interfere with the tub (for example, axial brackets) should not interfere with the cabinet light or cabinet left. In consideration of this, the ratio may be designed not to exceed eight.

The smaller the difference between the size of the cabinet and the diameter of the drum that is installed and rotated in the inside of the cabinet, the larger the volume of the drum can be as large as possible under the limitation of the size of the washing machine. And this makes it possible to increase the capacity of the washing machine with respect to the size of the washing machine appearance. The capacity of the washing apparatus may be determined by the maximum amount of laundry that can be washed, that is, the amount of laundry. For example, a 9kg class, 11kg class washing machine is a maximum amount of 9kg, 11kg. In general, as the capacity of the washing apparatus is increased, the volume of the drum and the tub must be increased.

In this embodiment, it is possible to provide a washing apparatus having a further increased capacity compared to the washing apparatus of the conventional structure on the basis of the external size of the washing apparatus, in particular, the width in the horizontal direction. That is, it can be increased to 11kg class that can only provide a capacity of about 9kg class in a 24-inch washing machine. In other words, it is possible to provide a laundry machine of 11 kg or less that exceeds the capacity that could have been conventionally provided for a 24 inch size (eg, 9.5 kg or more). On the other hand, the volume of the drum can be increased to about 78L. For 24-inch sizes, the volume of the drum can be between 65 and 78 liters.

Or, if it is based on a 27-inch size, it is possible to provide a washing apparatus of about 13kg or less in excess of the capacity that can be provided conventionally.

On the other hand, the rear gasket may be made of a variety of materials despite its name. In addition to the material generally used as a gasket, the material may also be utilized as long as it can be made to reduce the amount of vibration transmitted to the tub. In addition, the shape of the rear gasket may also be designed to have such a shape as long as it can relatively minimize vibration transmission to the tub.

In addition, the names used for the components of the present invention should not be construed as being limited thereto despite the dictionary or technical meaning of the words themselves. At least some of the names of the components are included for convenience, and are not intended to limit the material, function, shape, etc. of the components. The components constituting the present invention should be defined and interpreted once by their function and role.
