Description

Deodorizing module and storage device including deodorizing module {DEODORIZING MODULE AND STORAGE DEVICE INCLUDING THE SAME}

The present invention relates to a deodorization module and a storage device including the deodorization module.

Generally, refrigerators are used to store food for a long period of time while preventing food spoilage, and the temperature of the refrigerator is usually controlled within the temperature range of 0 to 10 degrees Celsius. However, if food is left in the refrigerator for more than a certain period of time, the food begins to spoil and a bad smell is generated, causing severe discomfort to the user. Additionally, when the smell of a specific food penetrates into other foods, the unique smell of the food is lost and the food is thrown away.

For this reason, most refrigerators are equipped with various types of deodorizing devices for the purpose of removing the odor of the food itself or odor caused by food spoilage, preventing the circulation of such odor, and sterilizing various microorganisms.

As a deodorizing device, a deodorizing filter containing manganese oxide (MnO2), copper oxide (CuO), and artificial enzyme catalyst is used on grid-shaped activated carbon. However, conventional deodorizing devices have a small amount of outside air sucked in at one time. Additionally, the air movement passage in the deodorizing device is narrow, so some of the inhaled air may be lost. Additionally, there is a problem in that sufficient deodorization is not achieved due to the small area of the deodorizing filter.

The problem to be solved by the present invention is to provide a deodorizing module capable of deodorizing air in a storage room and a storage device including the deodorizing module.

Another problem to be solved by the present invention is to provide a deodorizing module in which air sucked into the deodorizing module is deodorized and a storage device including the deodorizing module.

According to an embodiment of the present invention, a housing, a centrifugal fan formed on one side of the housing, an inlet for sucking in external air, and a centrifugal fan located between the inlet and the other side of the housing opposing one side of the housing and sucking in air. fan), formed on one side of the housing, an outlet for discharging the air sucked in through the centrifugal fan to the outside of the housing, a passage connecting the outlet of the centrifugal fan and the outlet, and a passage between the centrifugal fan and the outlet in the flow path. A deodorizing module is provided including a photocatalyst bar and a light source module disposed in the flow path and irradiating ultraviolet rays to the photocatalyst bar.

According to another embodiment of the present invention, a storage device is provided including a storage compartment having an internal space and the deodorizing module installed in the storage compartment to deodorize air in the storage compartment.

The deodorizing module according to an embodiment of the present invention enables efficient air deodorization because air sucked by a centrifugal fan passes through a photocatalyst bar disposed on the flow path.

The objectives, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments taken in conjunction with the accompanying drawings. The embodiments introduced below are provided as examples to ensure that the idea of the present invention can be sufficiently conveyed to those skilled in the art. Accordingly, the present invention is not limited to the embodiments described below and may be embodied in other forms. In this specification, when adding reference numbers to components in each drawing, it should be noted that identical components are given the same number as much as possible even if they are shown in different drawings. In addition, terms such as “first”, “second”, “one side”, “other side”, “top”, “bottom”, “upper”, “lower”, etc. are used to distinguish one component from another component. As used for this purpose, the components are not limited by the above terms.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

According to an embodiment of the present invention, a housing, a centrifugal fan formed on one side of the housing, an inlet for sucking in external air, and a centrifugal fan located between the inlet and the other side of the housing opposing one side of the housing and sucking in air. fan), formed on one side of the housing, an outlet for discharging the air sucked in through the centrifugal fan to the outside of the housing, a passage connecting the outlet of the centrifugal fan and the outlet, and a passage between the centrifugal fan and the outlet in the flow path. A deodorizing module is provided including a photocatalyst bar and a light source module disposed in the flow path and irradiating ultraviolet rays to the photocatalyst bar.

The air sucked in by the centrifugal fan passes through the photocatalyst bar and is discharged to the outside of the housing through the outlet. At this time, since the centrifugal fan is placed on the intake port and directly sucks in external air, a large amount of air can be sucked into the deodorizing module. Additionally, by adopting a centrifugal fan, the direction of the sucked air can be easily changed.

The flow path is formed by flow path side walls surrounding the photocatalyst bar and the light source module. Additionally, one side of the flow path side wall is in close contact with one side inside the housing, and the other side of the flow path side wall is in close contact with the other side inside the housing opposite the one side inside the housing. A flow path opening connected to the outlet of the centrifugal fan is formed on the flow path side wall. The flow path opening has the same size as the outlet of the centrifugal fan. Therefore, the air sucked in by the centrifugal fan can be discharged into the flow path without loss.

The channel side wall located between the back inside the housing and the light source module or the back inside the housing and the photocatalyst bar has an inclined inner wall. The side wall of the channel having an inclined inner wall becomes thinner from one side to the other. By having a sloping inner wall, the pressure loss that occurs when air hits the flow path side wall can be reduced.

The channel side walls are formed of a reflective material or the inner wall is coated with a reflective material.

The width of the flow path increases from the outlet of the centrifugal fan to the deodorizing area where the photocatalyst bar and light source module are placed. Additionally, the width of the flow path decreases as it moves from the deodorization area toward the outlet. The deodorization area is the part where the width of the flow path is the largest. For example, the flow path is octagonal in cross section. Due to this flow path structure, the air sucked from the centrifugal fan spreads widely and passes through the photocatalyst bar, allowing sufficient deodorization of the air. In the embodiment of the present invention, the flow path is not limited to a structure with an octagonal cross-section. The flow path may have a polygonal or oval cross-sectional structure. Additionally, the flow path may have a cross-sectional structure having two parallel straight lines and two curves connecting one end and the other end of the two straight lines, respectively. Additionally, the flow path can be formed in various structures other than those described above.

Both sides of the photocatalyst bar are in close contact with the channel side walls located on both sides of the photocatalyst bar. Additionally, one side of the photocatalyst bar is in close contact with one side inside the housing, and the other side is in close contact with the other side inside the housing. That is, the photocatalyst bar is formed to block the air movement path. Therefore, all air sucked into the deodorization module passes through the photocatalyst bar, enabling efficient air deodorization.

On the inner wall of the flow path, bar fixing parts for fixing the photocatalyst bar to the flow path are formed to face each other. Both sides of the photocatalyst bar are respectively inserted into the bar fixture. Therefore, the photocatalyst bar is fixed within the flow path by the bar fixing part.

One side of the light source module is spaced apart from one side inside the housing, and the other side is spaced apart from the other side inside the housing. Additionally, the light source module is disposed between the centrifugal fan and the photocatalyst bar. Alternatively, the light source module is disposed between the photocatalyst bar and the discharge portion.

The light source module includes a light source substrate and an ultraviolet light source. Additionally, the light source module may further include to improve the heat dissipation function.

On the inner wall of the flow path, module fixing parts for fixing the light source module to the flow path are formed to face each other. Both sides of the light source module are respectively inserted into the module fixing part. Therefore, the light source module is fixed within the flow path by the module fixing part.

The housing has a centrifugal fan, a flow path, a photocatalyst bar, and a light source module disposed therein, and includes a body with at least one side open, an inlet and an outlet formed on one side, and a cover formed to cover the open portion of the body. The housing and cover can be separated and combined.

The housing may further include a fastening part. The fastening portion protrudes outward from the outer wall of the housing and has a curved structure.

The housing is made of a reflective material or the inner wall is coated with a reflective material.

The light source substrate further includes a centrifugal fan and a control substrate that applies power and control signals to the light source module.

The outlet of the light source substrate may be disposed between the photocatalyst bar and the light source module.

According to another embodiment of the present invention, it includes a storage compartment having an internal space and the above-described deodorizing module that is mounted on the storage compartment and deodorizes the air in the storage compartment. The deodorization module is mounted on one side of the storage room.

The storage compartment is formed on the inner wall of the storage compartment and includes a fastening groove in which the bent portion of the fastening part can be inserted. The fastening part of the deodorizing module is inserted into the fastening groove and the deodorizing module is mounted on the inner wall of the storage room. The storage room is a refrigerator or refrigerator.

According to an embodiment of the present invention, the deodorizing module 100 includes a housing 110, an inlet 120, a centrifugal fan 140, an outlet 130, a flow path 150, a photocatalyst bar 160, and a light source module ( 170) and a control board 180.

The housing 110 accommodates a centrifugal fan 140, a photocatalyst bar 160, a light source module 170, and a control board 180 therein. Additionally, an inlet 120 and an outlet 130 are formed in the housing 110. Additionally, a flow path 150 is formed inside the housing 110 by a flow path side wall 151.

The housing 110 is divided into a main body 111 and a cover 112. The main body 111 has at least one side open, and a centrifugal fan 140, a flow path 150, a photocatalyst bar 160, and a light source module 170 are disposed inside. In addition, the cover 112 has an intake port 120 and an outlet port 130 formed on one side, and is formed to cover the open portion of the main body 111.

In FIG. 1, the cover 112 becomes one side and a side of the housing 110, and the main body 111 becomes the other side of the housing 110. However, the present invention is not limited to the structure of the housing 110 in FIG. 1. The structure of the housing 110 can be changed according to the selection of a person skilled in the art.

A centrifugal fan 140, a flow path 150, a photocatalyst bar 160, and a light source module 170 are disposed on the inner wall of the main body 111. Here, the inner wall of the main body 1110 faces one surface of the cover 112.

The cover 112 is combined with the main body 111 and has a structure that surrounds the centrifugal fan 140, the flow path 150, the photocatalyst bar 160, and the light source module 170. Additionally, both sides of the cover 112 have a structure in which the distance between them becomes narrower from one direction to the other. This structure can reduce the volume of the deodorizing module 100 compared to a structure in which both sides of the cover 112 are parallel. Accordingly, space consumption by the deodorizing module 100 can be reduced. However, the structure of the main body 111 and the cover 112 is not limited to this. The structures of the main body 111 and the cover 112 can be changed according to the selection of a person skilled in the art. The body 111 and cover 112 formed in this way can be separated and combined.

The housing 110 is made of a reflective material or its inner wall is coated with a reflective material. Alternatively, only a portion of the inner wall of the housing 110 corresponding to the flow path 150 may be coated with a reflective material.

The intake port 120 is a hole for sucking the outside air of the deodorization module 100 into the inside of the housing 110. The intake port 120 is formed on one side of the housing 110. Additionally, the suction port 120 is formed in an area where the centrifugal fan 140 is disposed.

The centrifugal fan 140 can easily change the direction of the sucked air. In an embodiment of the present invention, the centrifugal fan 140 discharges the sucked air into the flow path 150 located on one side of the centrifugal fan 140.

The centrifugal fan 140 is disposed between the suction port 120 and the other surface of the housing 110. At this time, the centrifugal fan 140 is arranged so that its rotation axis is perpendicular to the suction port 120. Therefore, the centrifugal fan 140 directly sucks air outside the deodorization module 100 through the intake port 120. Additionally, the centrifugal fan 140 discharges the sucked air through a separately formed outlet 141. The centrifugal fan 140 may be arranged to contact or be spaced apart from the suction port 120.

The centrifugal fan 140 may be fixed to the inner wall of the housing 110 using screws. However, the method by which the centrifugal fan 140 is fixed to the housing 110 is not limited to this. The centrifugal fan 140 may be fixed to the housing 110 by any known method.

The outlet 130 is a hole through which air deodorized inside the housing 110 is discharged to the outside. The outlet 130 is formed on one side of the housing 110. At this time, the outlet 130 is located within the area where the flow path 150 is formed. The outlet 130 is located in a space in the flow path 150 in the direction of the outlet surface of the photocatalyst bar 160. Here, the outlet surface of the photocatalyst bar 160 is the surface through which air passes through the photocatalyst bar 160 and exits.

The flow path 150 is a passage connecting the centrifugal fan 140 and the outlet 130. The flow path 150 is formed by a flow path side wall 151 surrounding the photocatalyst bar 160 and the light source module 170.

A flow path opening 152 is formed on the flow path side wall 151 forming the flow path 150. The flow path opening 152 is connected to the outlet 141 of the centrifugal fan 140. The flow path opening 152 has the same size as the outlet of the centrifugal fan 140. The air sucked in by the centrifugal fan 140 is discharged into the flow path 150 through the flow path opening 152. One surface of the flow path side wall 151 is in close contact with one surface inside the housing 110. Additionally, the other surface of the flow path side wall 151 is in close contact with the other surface inside the housing 110. Accordingly, the air flowing into the flow path 150 is discharged to the outside of the housing 110 through the outlet 130. Here, one surface inside the housing 110 is the inner wall of the cover 112. Additionally, the other surface inside the housing 110 is the inner wall of the main body 111. Additionally, one surface inside the housing 110 and the other surface inside the housing 110 face each other.

According to an embodiment of the present invention, the width of the flow path 150 gradually increases as it moves from the centrifugal fan 140 to the deodorizing area. Additionally, the width of the flow path 150 gradually decreases as it moves from the deodorization area to the area where the outlet 130 is located. Here, the deodorization area is an area where air deodorization occurs and the light source module 170 and the photocatalyst bar 160 are disposed. The desorption area in the flow path 150 has the largest width. That is, the portion of the flow path 150 where the photocatalyst bar 160 and the light source module 170 are disposed has the largest width. For example, the flow path 150 has an octagonal cross-section.

The air discharged from the centrifugal fan 140 spreads widely through the flow path 150 having this structure and passes through the light source module 170 and the photocatalyst bar 160. In other words, air deodorization occurs in a large space. Therefore, air deodorization performance can be improved.

The flow path side wall 151 located between the inner wall of the housing 110 and the light source module 170 has an inclined inner wall 153. The thickness of this flow path side wall 151 becomes thinner from the other side to one side. The flow path side wall 151 having this structure serves as a guide to direct the air within the flow path 150 toward the outlet 130. When the air in the flow path 150 moves to the outlet 130, it hits the flow path side wall 151, causing a loss of air pressure. However, the flow path side wall 151 having an inclined inner wall 153 has a smaller air pressure loss than the flow path side wall without an slope. That is, air pressure loss is reduced by the flow path side wall 151 according to an embodiment of the present invention.

The channel side wall 151 is formed of a reflective material or the inner wall is coated with a reflective material.

The photocatalyst bar 160 is disposed between the light source module 170 and the outlet 130 in the flow path 150. The photocatalyst bar 160 has a bar structure with a plurality of through holes. For example, the photocatalyst bar 160 is made of a porous ceramic material. Alternatively, the photocatalyst bar 160 is formed of a metal foam material containing nickel (Ni), iron (Fe), aluminum (Al), chromium (Cr), etc. A photocatalyst material is coated on the surface of the photocatalyst bar 160. The photocatalytic material includes at least one from the group of TiO2, ZnO, ZrO2, and WO3. Alternatively, it is possible that the photocatalyst bar 160 itself includes a photocatalyst material.

According to an embodiment of the present invention, ultraviolet rays emitted from the ultraviolet light source 172 react with the photocatalyst material of the photocatalyst bar 160 to generate hydroxyl radicals (ㆍOH). At this time, the generated hydroxyl radicals decompose and remove pollutants or odorous substances. That is, the air flowing into the flow path 150 is deodorized while passing through the through hole of the photocatalyst bar 160.

Both sides of the photocatalyst bar 160 are in close contact with the channel side walls 151 located on both sides of the photocatalyst bar 160, respectively. One side of the photocatalyst bar 160 is in close contact with one side of the inside of the housing 110. Additionally, the other side of the photocatalyst bar 160 is in close contact with the other side inside the housing 110. Accordingly, the air flowing into the flow path 150 passes through the photocatalyst bar 160 and moves to the outlet 130. Ultimately, the air discharged to the outside of the housing 110 through the outlet 130 is the air deodorized by the photocatalyst bar 160 and the light source module 170.

The photocatalyst bar 160 is fixed to the flow path 150 by the bar fixing part 191. The bar fixing portion 191 is formed on the flow path side wall 151 and is formed to protrude inward. Additionally, the bar fixing portion 191 is formed to have a groove penetrating the inside from one side to the other side. Accordingly, both sides of the photocatalyst bar 160 are inserted into the grooves of the bar fixing part 191 and are fixed to the flow path 150.

In an embodiment of the present invention, the photocatalyst bar 160 is fixed to the flow path 150 by the bar fixing part 191. However, the method of fixing the photocatalyst bar 160 to the flow path 150 is not limited to this. The method by which the photocatalyst bar 160 is fixed to the flow path 150 can be changed according to the selection of a person skilled in the art among known techniques.

The light source module 170 is disposed between the centrifugal fan 140 and the photocatalyst bar 160 in the flow path 150. Both sides of the light source module 170 are in close contact with the channel side walls 151 located on both sides of the light source module 170, respectively. Here, both sides of the light source module 170 are both sides of the light source substrate 171 and the heat sink 173. Alternatively, when the heat sink 173 is omitted or the heat sink 173 is formed in a part of the light source substrate 171, both sides of the light source module 170 may be both sides of the light source substrate 171.

One side of the light source module 170 is spaced apart from one side inside the housing 110. The other side of the light source module 170 is spaced apart from the other side inside the housing 110. That is, a space is formed between one side and the other side of the light source module 170 and the housing 110. The air flowing into the flow path 150 moves through this space.

The light source module 170 may be fixed to the flow path 150 by the module fixing part 192. The module fixing portion 192 is formed on the flow path side wall 151 and is formed to protrude inward. Additionally, the module fixing part 192 has a groove formed on one side. The depth of the groove may be determined depending on the height at which the light source module 170 will be located. By inserting both sides of the light source module 170 into the groove of the module fixing part 192 formed in this way, the light source module 170 is fixed to the flow path 150.

In an embodiment of the present invention, the light source module 170 is fixed to the flow path 150 by the module fixing part 192. However, the method of fixing the light source module 170 to the flow path 150 is not limited to this. The method by which the light source module 170 is fixed to the flow path 150 can be changed according to the selection of a person skilled in the art among known techniques.

The light source module 170 includes a light source substrate 171, an ultraviolet light source 172, and a heat sink 173.

The light source substrate 171 is electrically connected to the ultraviolet light source 172 and applies an electrical signal to the ultraviolet light source 172. For example, the light source substrate 171 may be a printed circuit board or a metal printed circuit board. If the light source substrate 171 is a metal printed circuit board, the heat dissipation performance of the deodorizing module 100 is improved.

The ultraviolet light source 172 is mounted on one side of the light source substrate 171 and irradiates ultraviolet rays to the photocatalyst bar 160. The ultraviolet light source 172 irradiates ultraviolet rays to the entrance surface of the photocatalyst bar 160. Here, the entrance surface of the photocatalyst bar 160 is a surface through which air flows to pass through the photocatalyst bar 160. For example, the ultraviolet light source 172 is a light emitting diode chip. One or more ultraviolet light sources 172 are mounted on the light source substrate 171. When a plurality of ultraviolet light sources 172 are mounted, ultraviolet rays can be evenly irradiated to the entire entrance surface of the photocatalyst bar 160. The number of ultraviolet light sources 172 can be changed according to the selection of a person skilled in the art.

The heat sink 173 is formed to dissipate heat from the ultraviolet light source 172 and the light source substrate 171. The heat sink 173 is formed on the other surface of the light source substrate 171. The heat sink 173 may be attached to the other side of the light source substrate using a thermally conductive adhesive. The heat sink 173 is made of a thermally conductive material. For example, the heat sink 173 is made of metal. In an embodiment of the present invention, the light source module 170 includes a heat sink 173 as an example. However, the present invention is not limited to this. The heat sink 173 may be omitted depending on the choice of a person skilled in the art. Additionally, the structure and forming method of the heat sink 173 may also be changed according to the selection of a person skilled in the art among known techniques.

The control board 180 supplies power and control signals to the centrifugal fan 140 and the light source module 170. Although not shown in FIG. 1, the control board 180 is electrically connected to the centrifugal fan 140 and the light source module 170 through a cable. In the present invention, the centrifugal fan 140 and the light source module 170 are explained as an example in which power and control signals are supplied from a single control board 180. However, it is possible for the centrifugal fan 140 and the light source module 170 to receive power and control signals from different control boards, respectively.

In FIG. 1 , the photocatalyst bar 160 and the light source module 170 are fixed within the flow path 150 by the bar fixing part 191 and the module fixing part 192, respectively. However, the present invention is not limited to this. That is, the bar fixing part 191 and the module fixing part 192 can be omitted depending on the selection of a person skilled in the art. At this time, any of the known methods can be used to fix the photocatalyst bar 160 and the light source module 170 to the flow path 150.

In addition, a fastening groove 820 for mounting the deodorizing module 400 is formed in the storage compartment 810. The fastening groove 820 is formed in the shape of a groove on the inner wall of the storage compartment 810. At this time, the fastening groove 820 is formed in a structure into which the fastening part 410 of the deodorizing module 400 can be inserted. That is, the fastening groove 820 is formed to have a space into which the bent portion of the fastening part 410 of the deodorizing module 400 can be inserted.

In an embodiment of the present invention, a plurality of fastening portions 410 are formed in the deodorizing module 400. Here, the fastening portion 410 formed on one side and the fastening portion 410 formed on the other side are formed to have different structures. This is a structure for easily fitting the fastening part 410 of the deodorizing module 400 into the fastening groove 820. In this way, all fastening parts 410 formed in the deodorizing module 400 do not necessarily have the same structure. The shape of the fastening part 410 may be changed according to the selection of a person skilled in the art.

Additionally, the structure of the fastening groove 820 of the storage compartment 810 may also be changed depending on the structure of the fastening part 410 of the deodorizing module 400.

The deodorizing module 400 is a deodorizing module according to the fourth embodiment. Although the deodorizing module 400 according to the fourth embodiment is described as an example, the present invention is not limited thereto. That is, the deodorizing module can be any of the deodorizing modules described in FIGS. 1 to 8.

The deodorization module 400 is mounted in the storage compartment 810. By inserting the fastening part 410 of the deodorizing module 400 into the fastening groove 820, the deodorizing module 400 is mounted on the inner wall of the storage compartment 810.

According to an embodiment of the present invention, both sides of the deodorizing module 400 are formed to have an inclination. That is, both sides of the cover 112 of the deodorizing module 400 have a structure in which the distance between them becomes narrower from one direction to the other. Here, one direction and the other direction are opposite directions. Based on Figure 1, one direction is the upper direction, and the other direction is the lower direction. This structure can minimize the reduction of the internal space of the storage compartment 810 by equipping the storage compartment 810 with the deodorizing module 400.

According to an embodiment of the present invention, the storage device 800 is described as an example of a refrigerator. However, the storage device 800 is limited to a refrigerator and any device that stores food is possible. For example, the storage device 800 may be a refrigerator.
