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, if the food is left in the refrigerator for a certain period of time, the food starts to be corrupted, resulting in a bad odor, which is very uncomfortable 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. Further, the air moving passage in the deodorizing device is narrow, and a part of the sucked air may be lost. In addition, there is a problem that sufficient deodorization is not achieved because the area of the deodorization filter is small.

The present invention provides a storage device including a deodorization module and a deodorization module capable of deodorizing the air in the storage compartment.

The present invention provides a storage device including a deodorization module and a deodorization module in which deodorization is performed on all 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 a lower surface of the housing for sucking outside air; an axial flow fan disposed in the suction port for sucking air; And a light source module for irradiating ultraviolet rays to the photocatalyst bar, the ultraviolet light source including a light source substrate and a photocatalyst bar disposed between the axial flow fan and the discharge port.

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

In the deodorization module according to the embodiment of the present invention, since the axial flow fan directly sucks the outside air, a large amount of air can be sucked.

In addition, in the deodorization module according to the embodiment of the present invention, the inside of the housing itself becomes a moving passage of air, and all the air inside the housing passes through the optical module bar, so that efficient air deodorization is possible.

According to an embodiment of the present invention, the deodorization module is formed on the bottom surface of the housing and the housing, and includes a suction port for sucking outside air, an axial flow fan disposed in the suction port for sucking air, A photocatalyst bar disposed between the axial flow fan and the discharge port, and a light source module including an ultraviolet light source and irradiating the photocatalyst bar with ultraviolet rays.

Since the axial flow 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.

The photocatalyst bar is arranged such that all the air sucked by the axial fan passes through the photocatalyst bar. The upper surface of the photocatalyst bar is in close contact with the upper surface of the inside of the housing, and the lower surface of the photocatalyst bar is in close contact with the lower surface of the inside of the housing. That is, the entire interior of the housing becomes a moving path of air. In addition, the photocatalyst bar is formed so as to block the air passage of the air. Therefore, all the air sucked into the deodorization module passes through the photocatalyst bar, so that efficient air deodorization is possible.

The light source module is disposed between the axial flow fan and the photocatalyst bar. Or the light source module is disposed between the photocatalyst bar and the rear surface of the interior of the housing. At this time, the light source module is disposed to be spaced apart from the rear surface of the inside of the housing. Therefore, it is possible to prevent condensation from occurring in the housing due to heat generated in the light source module.

Also, the upper side of the light source module is spaced apart from the upper surface of the housing, and the lower side of the light source module is separated from the lower side of the housing.

The light source substrate is a metal printed circuit board. When the light source substrate is a metal printed circuit board, it is efficient for heat dissipation. In addition, the light source module may further include a heat sink for improving the heat dissipation function.

When the light source module includes a plurality of ultraviolet light sources, it is possible to uniformly irradiate ultraviolet rays to the photocatalyst module.

The outlet is formed on both sides of the housing. At this time, a rear exhaust guide formed on the rear surface of the housing to guide the deodorized air to the exhaust port is further formed. The rear discharge guide is a triangular prismatic shape with a curved side surface. The rear discharge guide guides the deodorized air to the discharge ports formed on both sides of the housing.

Or the discharge port is formed on the lower surface of the housing. In this case, the rear discharge guide is omitted.

The deodorization module further includes a bottom discharge guide formed on the lower surface of the inside of the housing, and formed between the photocatalyst bar and the outlet. And the drain guide protrudes from the lower surface of the inside of the housing to the lower portion of the ultraviolet light source.

The housing further includes an air inlet guide formed to be positioned between both sides of the axial flow fan and both side walls of the housing.

The portion of the lower surface of the housing where the suction portion is formed is an inclined surface.

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

The deodorization module further includes a control board for applying power and control signals to the axial fan and the light source module.

The deodorization module further includes an outer guide formed to protrude outward along the outer circumference of the housing. At this time, the discharge port is formed at the lower portion of the outer guide.

The housing is divided into a main body and a cover which can be separated and combined with each other. The body is open at the top and accommodates an inlet, an axial fan, an outlet, a photocatalyst bar and a light source module. The cover covers the open top of the body.

A cover guide is formed on the lower surface of the cover. The cover guide is located on the upper portion of the axial fan when the main body and the cover are engaged, and has a structure in which the thickness becomes thinner toward the outlet direction.

According to another embodiment of the present invention, the storage device includes a storage room having an internal space and a deodorization module mounted on the storage room to deodorize the storage room. Here, the storage room may be a refrigerator or a hot store.

The deodorization module is mounted on the upper surface of the storage chamber.

In addition, a groove type deodorization module mounting portion is further formed in the storage chamber, and the deodorization module is inserted into the deodorization module mounting portion. At this time, the suction part and the discharge part of the deodorization module are exposed to the inside space of the storage compartment. At this time, when the outer guide is formed on the deodorization module, the upper surface of the outer guide contacts the storage chamber, and the lower surface of the outer guide is exposed to the inner space of the storage chamber.

1 to 4, the deodorization module 100 according to the first embodiment includes a housing 110, an inlet 120, an axial flow fan 130, a light source module 140, a photocatalyst bar 150, (160) and a control board (170).

The housing 110 accommodates the axial fan 130, the photocatalyst bar 150, the light source module 140, and the control board 170 in the interior of the housing 110 according to an embodiment of the present invention.

The suction port 120 is a hole for sucking the outside air into the inside of the housing 110. The suction port 120 is formed on the lower surface of the housing 110. In addition, the suction port 120 is formed in a region where the axial flow fan 130 is disposed.

Suction guides 180 may be formed on both sides of the suction port 120. The suction guide 180 is formed to protrude upward from the lower surface of the inside of the housing 110. In addition, the suction guide 180 is formed to be open between the axial fan 130 and the light source module 140. Therefore, the suction guide 180 serves as a guide to move the air sucked into the axial fan 130 through the suction port 120 to the light source module 140.

The axial flow fan 130 is disposed on the inlet 120. Here, the axial flow fan 130 is a blower whose flow direction is parallel to the rotation axis of the fan. The rotary shaft of the axial fan 130 is disposed at a right angle to the lower surface of the suction port 120. Accordingly, the axial flow fan 130 directly sucks the air outside the housing 110 through the inlet 120 and directly discharges the air into the housing 110. The axial flow fan 130 thus arranged can suck a large amount of air at one time, thereby improving the deodorization efficiency.

According to the embodiment of the present invention, the axial flow fan 130 can be fixed inside the housing 110 in such a manner as to be sandwiched between the suction guides 180. Or the axial flow fan 130 can be engaged with the lower surface of the housing 110 by screws. The method in which the axial flow fan 130 is fixed inside the housing 110 is not limited thereto, and can be changed according to the choice of a person skilled in the art.

The light source module 140 is disposed between the axial fan 130 and the photocatalyst bar 150. The light source module 140 includes a light source substrate 141, a heat sink 142, and an ultraviolet light source 143.

The light source substrate 141 is electrically connected to the ultraviolet light source 143 and applies an electric signal to the ultraviolet light source 143. For example, the light source substrate 141 may be a printed circuit board or a metal printed circuit board. If the light source substrate 141 is a metal printed circuit board, the heat radiation performance of the deodorization module 100 is improved.

Both side surfaces of the light source substrate 141 are fixed to both sides of the inside of the housing 110, respectively. For example, the light source substrate 141 may be fixed inside the housing 110 by the substrate fixing unit 191. The substrate fixing part 191 is formed to protrude inward from both sides of the inside of the housing 110. Further, the substrate fixing portion 191 is formed to have a groove penetrating the upper surface and the inside. At this time, the depth of the groove is determined according to the height at which the light source substrate 141 is to be positioned. The light source substrate 141 is fixed inside the housing 110 by inserting both side surfaces of the light source substrate 141 into the grooves of the substrate fixing portions 191.

The upper surface of the light source substrate 141 is spaced apart from the upper surface of the interior of the housing 110. The lower surface of the light source substrate 141 is spaced apart from the lower surface of the housing 110. The space between the light source substrate 141 and the housing 110 serves as a passage for air. That is, the air sucked by the axial flow fan 130 passes through the space between the upper and lower portions of the light source substrate 141 and moves to the photocatalytic bar 150.

The ultraviolet light source 143 is mounted on one surface of the light source substrate 141. The ultraviolet light source 143 irradiates ultraviolet rays to the photocatalyst bar 150. For example, the ultraviolet light source 143 is a light emitting diode chip. One or more ultraviolet light sources 143 may be mounted on the light source substrate 141. When a plurality of ultraviolet light sources 143 are mounted, the photocatalyst bar 150 can be uniformly irradiated with ultraviolet rays. The number of the ultraviolet light sources 143 can be changed as needed by those skilled in the art.

The heat sink 142 is formed on the other surface of the light source substrate 141. The heat sink 142 may be attached to the other surface of the light source substrate 141 using a thermally conductive adhesive. The heat sink 142 is formed for dissipating the ultraviolet light source 143 and the light source substrate 141. The heat sink 142 is formed of a thermally conductive material. For example, the heat sink 142 is made of metal. In the exemplary embodiment of the present invention, the light source module 140 includes the heat sink 142. However, the present invention is not limited thereto. The heat sink 142 may be omitted according to the choice of a person skilled in the art. Also, the material of the heat sink 142 and the manner in which the heat sink 142 is attached to the light source substrate 141 can be changed according to the choice of a person skilled in the art.

The photocatalyst bar 150 is disposed between the light source substrate 141 and the exhaust port 160. The photocatalyst bar 150 is formed in a bar structure having a plurality of through holes. For example, the photocatalytic bar 150 is formed of a porous ceramic material. Or the photocatalyst bar 150 is formed of a metal foam material including nickel (Ni), iron (Fe), aluminum (Al), chromium (Cr) A photocatalyst material is coated on the surface of the photocatalyst bar 150. The photocatalyst material comprises at least one of the group of the group of TiO2, ZnO, ZrO2, WO3. Or the photocatalyst bar 150 itself may include a photocatalyst material.

According to the embodiment of the present invention, ultraviolet rays emitted from the ultraviolet light source 143 and the photocatalyst material of the photocatalyst bar 150 react with each other to generate a hydroxyl radical (.OH). At this time, the produced hydroxyl radical is decomposed and removed by pollutant or odorous substance. That is, the air sucked by the axial flow fan 130 is deodorized while passing through the through hole of the photocatalytic bar 150.

The photocatalyst bar 150 is disposed so that all the air sucked by the axial flow fan 130 passes through the photocatalyst bar 150. For example, both sides of the photocatalytic bar 150 are in close contact with both sides of the interior of the housing 110. The upper surface of the photocatalyst bar 150 is in close contact with the upper surface of the inside of the housing 110. The lower surface of the photocatalyst bar 150 is in close contact with the lower surface of the inside of the housing 110. Therefore, since all the side surfaces of the photocatalyst bar 150 are in close contact with the inside of the housing 110, the air must pass through the photocatalyst bar 150. As a result, all the air that has flowed into the housing 110 is deodorized by the light source module 140 and discharged to the outside of the housing 110.

The photocatalyst bar 150 may be fixed inside the housing 110 by a bar fixing unit 195. The bar fixing portion 195 is formed to protrude inward from both sides of the inside of the housing 110. [ The bar fixing portion 195 is formed to have a groove penetrating from the upper surface to the lower surface. Therefore, the photocatalyst bar 150 is inserted into the groove of the bar fixing part 195 on both sides and fixed to the inside of the housing 110.

The substrate fixing portion 191 and the bar fixing portion 195 are separately formed from the housing 110 in the embodiment of the present invention. However, the substrate fixing part 191 and the fixing part 195 may be integrally formed with the housing 110. [

Outlets 160 are formed on both sides of the housing 110. At this time, the outlet 160 is formed between the photocatalyst bar 150 and the rear surface of the inside of the housing 110. The discharge port 160 is a hole for discharging the deodorized air to the outside while passing through the photocatalytic bar 150.

A rear discharge guide 185 is formed on the rear surface of the housing 110. The rear discharge guide 185 has a triangular columnar structure whose side surface is curved. One side surface of the rear discharge guide 185 is in contact with the housing 110, and the other two surfaces are curved and facing the discharge port 160, respectively. The deodorized air is guided to the discharge port 160 by the rear discharge guide 185 as described above.

The control board 170 applies power and control signals to the axial fan 130 and the light source module 140. In the present invention, the axial fan 130 and the light source module 140 receive power and control signals from one control board 170 as an example. However, the present invention is not limited thereto. That is, the axial fan 130 and the light source module 140 can receive power and control signals from different control boards. Alternatively, the control board 170 may be omitted, and the axial fan 130 and the light source module 140 may receive power and control signals directly from the outside.

The housing 110 is formed of a reflective material. Alternatively, the housing 110 may be coated with a reflective material. At this time, the rear discharge guide 185 formed on the housing 110 may be formed of a reflective material or coated with a reflective material.

In the deodorization module 100 according to the embodiment of the present invention, the inside of the housing 110 itself becomes a moving path of air. Therefore, it is possible to prevent the sucked air from being lost during the movement. Further, the photocatalyst bar 150 is formed so as to cross the moving path of the air. Therefore, all the air sucked into the deodorization module 100 passes through the photocatalytic bar 150. Therefore, the deodorization module 100 according to the embodiment of the present invention can suck air efficiently by sucking a large amount of outside air and deodorizing all the inhaled air without sucked in air loss.

An explanation of the same configuration will be omitted from the description of FIG. 1 to FIG.

According to an embodiment of the present invention, the photocatalytic bar 150 is disposed between the axial fan 130 and the light source module 140. Further, the light source module 140 is disposed between the photocatalyst bar 150 and the exhaust port 160. The ultraviolet light source 143 of the light source module 140 irradiates ultraviolet rays to the photocatalyst bar 150.

The air introduced by the axial flow fan 130 is deodorized while passing through the photocatalytic bar 150. Then, the deodorized air passes through the space above and below the light source module 140 and moves to the outlet 160.

According to an embodiment of the present invention, a discharge port 160 is formed on the lower surface of the housing 110. Further, the outlet 160 is formed between the light source module 140 and the rear surface of the inside of the housing 110. Since the discharge port 160 is formed on the lower surface of the housing 110, the air that is more easily deodorized than when the discharge port 160 is formed on the side surface of the housing 110 can be discharged to the outside of the housing 110. When the discharge port 160 is formed on the lower surface of the housing 110 as described above, the rear discharge guide 185 of the first embodiment can be omitted.

The air that has passed through the photocatalyst bar 150 moves to the discharge port 160 by moving as short as possible. Thus, most of the air passes through the lower portion of the photocatalytic bar 150. The bottom discharge guide 310 formed between the photocatalyst bar 150 and the discharge port 160 prevents intensive flow of air only in a certain area. That is, the bottom discharge guide 310 allows the air to pass over the entire surface of the photocatalytic bar 150.
