Description

DEODORIZING MODULE AND STORAGE DEVICE INCLUDING THE SAME [0002]

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

Generally, a refrigerator is used to store food for a long period of time while preventing the decay of food. Usually, the temperature of the refrigerator is controlled within a temperature range of 0 to 10 ° C. However, when the food is left in the refrigerator for a certain period of time, the food starts to be corrupted and the odor is generated, which causes a serious discomfort to the user. In addition, when the smell of certain foods is permeated into other foods, the inherent odor of the food is lost and the food is discarded.

For this reason, most of the refrigerators are provided with various deodorizing apparatuses for removing the odor due to the food or food odor, and sterilizing various microorganisms while preventing the odor from circulating.

As deodorization apparatus, deodorization filter in which manganese oxide (MnO2), copper oxide (CuO), artificial enzyme catalyst, etc. are carried on lattice type activated carbon is used. However, the conventional deodorizing device has a small amount of outside air sucked in at a time. In addition, the air moving passage in the deodorizing device is narrow, and some of the sucked air may be lost. Further, there is a problem that the area of the deodorization filter is small and sufficient deodorization is not achieved.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a storage device including a deodorization module and a deodorization module capable of deodorizing air in the storage compartment.

Another object of the present invention is to provide a storage device including a deodorization module and a deodorization module in which deodorization is performed on the air sucked into the deodorization module.

According to an embodiment of the present invention, there is provided an air conditioner comprising: a housing; a suction port formed on one surface of the housing for sucking outside air; a centrifugal fan disposed between the suction port and the other surface of the housing, a fan which is formed on one side of the housing and has a discharge port for discharging the air sucked through the centrifugal fan to the outside of the housing, a flow path for connecting the outlet of the centrifugal fan to the discharge port, There is provided a deodorization module including a light source module which is disposed in an arranged photocatalytic bar and a flow path and irradiates ultraviolet rays to the photocatalyst bar.

According to another embodiment of the present invention, there is provided a storage device including a storage room having an internal space and the deodorization module mounted on the storage room to deodorize the storage room.

In the deodorization module according to the embodiment of the present invention, the air sucked by the centrifugal fan passes through the photocatalyst bar disposed on the flow path, so that efficient air deodorization is possible.

BRIEF DESCRIPTION OF THE DRAWINGS The objectives, specific advantages and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. The following embodiments are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. It is also to be understood that terms such as " first, "second," one side, "" second," " top, " And the constituent elements are not limited by these terms.

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

According to an embodiment of the present invention, there is provided an air conditioner comprising: a housing; a suction port formed on one surface of the housing for sucking outside air; a centrifugal fan disposed between the suction port and the other surface of the housing, a fan which is formed on one side of the housing and has a discharge port for discharging the air sucked through the centrifugal fan to the outside of the housing, a flow path for connecting the outlet of the centrifugal fan to the discharge port, There is provided a deodorization module including a light source module which is disposed in an arranged photocatalytic bar and a flow path and irradiates ultraviolet rays to the photocatalyst bar.

The air sucked by the centrifugal fan passes through the photocatalyst bar and is discharged to the outside of the housing through the discharge port. At this time, since the centrifugal fan is disposed on the suction port and directly sucks the outside air, a large amount of air can be sucked into the deodorization module. Also, the adoption of a centrifugal fan makes it possible to easily change the direction of the sucked air.

The flow path is formed by a flow path wall surrounding the photocatalyst bar and the light source module. One surface of the flow path side wall is in close contact with one surface of the inside of the housing, and the other surface of the flow path side wall is in close contact with the other surface inside the housing facing one surface of the inside of the housing. On the side wall of the flow channel, a flow path opening communicating with the outlet of the centrifugal fan is formed. The flow path opening has the same size as the outlet of the centrifugal fan. Therefore, the air sucked by the centrifugal fan can be discharged to the flow path without loss.

The side wall of the flow path located between the backside of the inside of the housing and the backside of the light source module or inside of the housing and the photocatalytic bar has an inclined inner wall. The thickness of the sidewall of the channel having the inclined inner wall becomes thinner from one surface to the other surface. By the inclined inner wall, the pressure loss caused when the air hits the side wall of the flow channel can be reduced.

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

The flow path increases in width from the outlet of the centrifugal fan toward the deodorizing area where the photocatalyst bar and the light source module are disposed. Further, the width of the flow path decreases from the deodorizing area to the direction in which the discharge port is located. The deodorization zone is the largest width of the channel. For example, the flow path is octagonal in cross section. Due to the structure of the flow path, the air sucked in the centrifugal fan spreads widely and passes through the photocatalyst bar, so that the air can be sufficiently deodorized. In the embodiment of the present invention, the flow path is not limited to a structure having an octagonal cross section. The flow path may have a polygonal or oval cross section. Further, the flow path may have a cross-sectional structure having two parallel lines and two curves connecting one end and the other end of the two lines, respectively. In addition, the flow path can be formed in various structures other than the above-described structure.

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

On the inner wall of the flow path, a bar fixing part for fixing the photocatalyst bar to the flow path is formed to face each other. Both sides of the photocatalytic bar are inserted into the bar zone. Therefore, the photocatalyst bar is fixed in the flow path by the bar fixing portion.

One side of the light source module is separated from one side of the inside of the housing, and the other side is separated from the other side of the inside of the housing. Further, the light source module is disposed between the centrifugal fan and the photocatalyst bar. Or the light source module is disposed between the photocatalyst bar and the exhaust part.

The light source module includes a light source substrate and an ultraviolet light source. In addition, the light source module may further include a heat dissipation function.

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

The housing includes a centrifugal fan, a flow path, a photocatalyst bar, and a light source module. The cover includes a body having at least one open side and a cover formed to cover the opened portion of the body. The housing and the cover can be separated and combined.

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

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

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

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

According to another embodiment of the present invention, there is provided a storage room having an inner space and a deodorization module mounted on the storage room to deodorize the storage room. The deodorization module is mounted on one side of the storage chamber.

The storage compartment is formed in the inner wall of the storage compartment and includes a fastening groove in which a bent portion of the fastening portion can be inserted. The coupling part of the deodorization module is inserted into the coupling groove and the deodorization module is mounted on the inner wall of the storage chamber.

1 is a perspective view of a deodorization module according to a first embodiment of the present invention. 2 is a bottom front view of the deodorization module according to the first embodiment of the present invention.

According to an embodiment of the present invention, the deodorization module 100 includes a housing 110, an inlet 120, a centrifugal fan 140, an outlet 130, a flow passage 150, a photocatalyst bar 160, 170 and a control board 180. [

The housing 110 accommodates therein a centrifugal fan 140, a photocatalyst bar 160, a light source module 170, and a control substrate 180. In addition, a suction port 120 and a discharge port 130 are formed in the housing 110. In addition, a flow path 150 formed by the flow path side wall 151 is formed in the housing 110.

The housing 110 is divided into a main body 111 and a cover 112. A centrifugal fan 140, a flow path 150, a photocatalyst bar 160, and a light source module 170 are disposed inside the main body 111. The cover 112 has a suction port 120 and a discharge port 130 formed on one surface thereof and is formed to cover an open portion of the main body 111.

 1, the cover 112 is a side surface and a side surface of the housing 110, and the main body 111 is a surface of the housing 110. As shown in FIG. However, the present invention is not limited to the structure of the housing 110 of FIG. The structure of the housing 110 can be changed according to the choice 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 coupled with the main body 111 to surround the centrifugal fan 140, the flow path 150, the photocatalyst bar 160, and the light source module 170. Further, both side surfaces of the cover 112 have a structure in which the spacing distance from one direction to the other decreases. Such a structure can reduce the volume of the deodorization module 100 when the cover 112 has a structure in which both sides are parallel. Therefore, the space consumption by the deodorization module 100 can be reduced. However, the structure of the main body 111 and the cover 112 is not limited thereto. The structure of the main body 111 and the cover 112 can be changed by a person skilled in the art. The body 111 and the cover 112 thus formed can be separated and combined.

The housing 110 is formed of a reflective material or the inner wall is coated with a reflective material. Or a portion of the inner wall of the housing 110 corresponding to the flow path 150 may be coated with a reflective material.

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

The centrifugal fan 140 can easily change the direction of the sucked air. In the embodiment of the present invention, the centrifugal fan 140 discharges the sucked air into the channel 150 located at one side of the centrifugal fan 140. [

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

The centrifugal fan 140 may be fixed to the inner wall of the housing 110 using a screw. However, the method in which the centrifugal fan 140 is fixed to the housing 110 is not limited thereto. The centrifugal fan 140 may be secured to the housing 110 by any method known in the art.

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

The flow path 150 connects the centrifugal fan 140 and the discharge port 130. The flow path 150 is formed of a flow path wall 151 surrounding the photocatalyst bar 160 and the light source module 170.

The flow path opening 152 is formed in the flow path side wall 151 constituting 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 by the centrifugal fan (140) is discharged to the flow path (150) through the flow path opening (152). One side of the flow path side wall 151 is in close contact with one surface of the inside of the housing 110. 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 introduced into the flow path 150 is discharged to the outside of the housing 110 through the discharge port 130. Here, one surface of the inside of the housing 110 is an inner wall of the cover 112. The other surface inside the housing 110 is the inner wall of the main body 111. One side of the inside of the housing 110 and the other side of the inside of the housing 110 are opposed to each other.

According to the embodiment of the present invention, the width of the flow path 150 gradually increases from the centrifugal fan 140 toward the deodorizing area. Also, the width of the flow path 150 gradually decreases from the deodorization area to the area where the discharge port 130 is disposed. Here, the deodorizing area is a region in which the light source module 170 and the photocatalyst bar 160 are disposed in a region where air is deodorized. The deodorizing region in the flow path 150 has the largest width. That is, the portion where the photocatalyst bar 160 and the light source module 170 are disposed in the flow path 150 has the largest width. For example, the flow path 150 has an octagonal cross-section.

The air discharged from the centrifugal fan 140 is widely spread by the flow path 150 having the above structure and passes through the light source module 170 and the photocatalyst bar 160. That is, the deodorizing action of air is performed in a wide space. Therefore, the deodorizing performance of the air 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 the flow path side wall 151 becomes thinner from one surface to the other surface. The flow path side wall 151 having such a structure serves as a guide for directing air in the flow path 150 toward the discharge port 130. When the air in the flow path 150 moves to the discharge port 130, the air is impinged against the flow path side wall 151 and pressure loss of air occurs. However, the flow path side wall 151 having the inclined inner wall 153 has a smaller air pressure loss than the flow path side wall having no inclination. That is, the pressure loss of air is reduced by the flow path side wall 151 according to the embodiment of the present invention.

The flow path 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 in the flow path 150 between the light source module 170 and the outlet 130. The photocatalyst bar 160 has a bar structure having a plurality of through holes. For example, the photocatalyst bar 160 is formed of a porous ceramic material. Or the photocatalyst bar 160 is formed of a metal foam material including nickel (Ni), iron (Fe), aluminum (Al), chromium (Cr) The surface of the photocatalyst bar 160 is coated with a photocatalyst material. The photocatalyst material comprises at least one of the group of the group of TiO2, ZnO, ZrO2, WO3. Or the photocatalyst bar 160 itself may include a photocatalyst material.

According to the embodiment of the present invention, the ultraviolet ray emitted from the ultraviolet light source 172 reacts with the photocatalyst material of the photocatalyst bar 160 to generate a hydroxyl radical (.OH). At this time, the produced hydroxyl radical decomposes and removes contaminants or odor substances. That is, air introduced into the flow path 150 is deodorized while passing through the through hole of the photocatalyst bar 160.

Both side surfaces of the photocatalyst bar 160 are in close contact with the flow path side wall 151 located on both sides of the photocatalyst bar 160. One side of the photocatalyst bar 160 is in close contact with one surface of the inside of the housing 110. The other side of the photocatalyst bar 160 is in close contact with the other side of the inside of the housing 110. Thus, the air introduced into the flow path 150 passes through the photocatalyst bar 160 and moves to the discharge port 130. The air exhausted to the outside of the housing 110 through the discharge port 130 is air that is 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 portion 191. The bar fixing portion 191 is formed on the flow path side wall 151 and is formed to protrude inward. The bar fixing portion 191 is formed to have a groove penetrating from the one surface to the other surface. Thus, the photocatalyst bar 160 is inserted into the groove of the bar fixing portion 191 on both sides and fixed to the flow path 150.

In the embodiment of the present invention, the photocatalyst bar 160 is fixed to the flow path 150 by means of the bar fixing portion 191 as an example. However, the method of fixing the photocatalyst bar 160 to the flow path 150 is not limited thereto. The method in 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 technologies.

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

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

The light source module 170 may be fixed to the flow path 150 by the module fixing portion 192. The module fixing portion 192 is formed on the flow path side wall 151 and protrudes inward. Further, the module fixing portion 192 is formed with a groove on one surface thereof. The depth of the groove can be determined according to the height at which the light source module 170 is to be positioned. Both side surfaces of the light source module 170 are inserted into the grooves of the module fixing portion 192 thus formed to fix the light source module 170 to the flow channel 150.

The light source module 170 is fixed to the flow channel 150 by the module fixing portion 192 in the embodiment of the present invention. However, the method of fixing the light source module 170 to the flow path 150 is not limited thereto. The method in 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 technologies.

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 electric 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 radiation performance of the deodorization module 100 is improved.

The ultraviolet light source 172 is mounted on one surface of the light source substrate 171 and emits ultraviolet rays to the photocatalyst bar 160. The ultraviolet light source 172 emits 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 a plurality of 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 uniformly irradiated to the entire entrance surface of the photocatalyst bar 160. The number of ultraviolet light sources 172 can be changed according to the choice of a person skilled in the art.

The heat radiating plate 173 is formed for dissipating the ultraviolet light source 172 and the light source substrate 171. The heat radiating plate 173 is formed on the other surface of the light source substrate 171. The heat radiating plate 173 may be attached to the other surface of the light source substrate using a thermally conductive adhesive. The heat sink 173 is formed of a thermally conductive material. For example, the heat sink 173 is made of metal. In the embodiment of the present invention, the light source module 170 includes the heat sink 173 as an example. However, the present invention is not limited thereto. The heat sink 173 may be omitted according to the choice of a person skilled in the art. Further, the structure and the forming method of the heat sink 173 may 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 supplied with power and control signals from one control board 180 as an example. However, the centrifugal fan 140 and the light source module 170 may receive power and control signals from different control substrates, respectively.

The photocatalyst bar 160 and the light source module 170 are fixed in the channel 150 by the bar fixing unit 191 and the module fixing unit 192, respectively. However, the present invention is not limited thereto. That is, the locking unit 191 and the module fixing unit 192 can be omitted according to the selection of a person skilled in the art. At this time, the method of fixing the photocatalyst bar 160 and the light source module 170 to the flow path 150 may be any of known methods.
