る。(Function) When the air passing through the circulation path comes into contact with the deodorizing body, odor components contained in the air are adsorbed by the deodorizing body. Then, when the heater is energized and the deodorizing body is heated by the heater, the odor components adsorbed in the deodorizing body are desorbed and oxidized and decomposed and removed. At this time, the deodorizing body is heated by directly receiving the radiant heat of the heater, and is also heated by the heat reflected by the reflective part of the cover, so that it is efficiently heated. The heated deodorizing body regenerates its absorption function by desorbing the adsorbed odor components.

Furthermore, the structure is simpler than that using an ozone generator. In addition, since the deodorizing body is efficiently heated, desorption and oxidative decomposition of odor components due to the heating are efficiently performed.

除去される。Now, in the above configuration, when the refrigerator is in cooling operation, the air inside the refrigerator is transferred to the cooler chamber 7 by the blowing action of the fan 8. It is circulated through the freezer compartment 2 and the return duct 10, and the cooler compartment 7. Supply duct 11. It is circulated through the cold storage room 3 and return duct 12. At this time, the cooler chamber 7
The air passing through comes into contact with the deodorizing body 15, and odor components contained in the air are absorbed by the adsorbent layer 15a of the deodorizing body 15 and removed.

Due to the heat generated, the cooler 6 is heated and defrost is performed.
At the same time, the deodorizing body 15 is heated. At this time, the deodorizing body 15 not only receives the radiant heat from the defrosting heater 13 directly on its lower surface and is heated, but also absorbs the heat radiated from the defrosting heater 13 toward the reflecting portion 14b of the cover 14. The radiated heat is reflected toward the deodorizing body 15 by the reflecting portion 14b as shown by arrow A, and the side surface is heated by the reflected heat. The heated deodorizing body 15 is heated so that the odor components adsorbed by the adsorbent in the absorbent layer 15a are removed, and at the same time, the odor components are oxidized and decomposed in the catalyst layer 15b and removed. Become. By heating the deodorizing body 15 in this manner, the adsorption function, that is, the deodorizing function is regenerated. At this time, the cover 14 plays a role of efficiently heating the deodorizing body 15 by confining the heat from the defrosting heater 13 downward, and also serves to efficiently heat the deodorizing body 15 and the defrosting heater 13 from the cooler 6. +1 protection against frost water. The heat insulating material 17 suppresses the heat from the deodorizing body 15 or bk from the cover 14, and also prevents the heat shock of the deodorizing body 15 caused by the defrosting water falling onto the cover 14 and rapidly cooling the force/<-14. It is rainproof.

うになる。Then, when the temperature of the cooler 6 reaches a predetermined defrosting end temperature or higher, the defrosting heater 13 is cut off and the defrosting operation ends. Then, when the compressor and the fan 8 are energized and the cooling operation is resumed, the odor components contained in the air in the refrigerator are sucked and removed by the deodorizing body 15 in the same manner as described above.

脱臭体１５を加熱するヒータとして除霜ヒータ１３を利
用しているので、別途専用のヒータを設ける必要がない
という利点がある。According to the embodiment described above, the deodorizing body 15 is the defrosting heater 13
Since the deodorizing function is regenerated by heating, the deodorizing function has a long lifespan, unlike those that simply adsorb with an adsorbent.In addition, this deodorizing device has a simpler structure than one that uses an ozone generator. It goes without saying that there is. Moreover, according to this structure, since the deodorizing body 15 has surfaces other than the top surface exposed, the area that comes into contact with the air inside the refrigerator is large, and the efficiency of adsorbing odor components is high. Further, when the deodorizing body 15 is heated by the defrosting heater 13, not only the lower surface of the deodorizing body 15 receives the radiant heat directly from the defrosting heater 13 and is heated, but also the side surface of the deodorizing body 15 is heated by the radiant heat reflected by the reflective part 14b of the cover 14. Since it is heated by reflected heat, the side surfaces are also heated to a high temperature, so that the heating efficiency is high and the desorption and oxidative decomposition of odor components are performed efficiently. Furthermore, according to this example,
Since the defrosting heater 13 is used as a heater for heating the deodorizing body 15, there is an advantage that there is no need to separately provide a dedicated heater.

This heater may preferably be controlled to be turned on and off in synchronization with the defrosting heater 13. In addition, the deodorizing body 15 may be divided into several L pieces instead of one piece that is long in the horizontal direction, and the deodorizing body 15 may not have a two-layer structure, for example, an adsorbent and a catalyst. It may also be a single layer made by mixing, bonding and solidifying.

得るという優れた効果を奏する。[Effect of the invention] As is clear from the above description, the deodorizing device of the present invention has the following effects:
#1 consists of a deodorizer that absorbs odor components and oxidizes and decomposes the odor components by being heated, a heater that heats the deodorizer, and a cover that covers the side of the deodorizer opposite to the heater side. Therefore, the structure is simple, and since the deodorizing body generates a tracheid function when heated, the life of the deodorizing function is long. In addition, a reflective part is provided on the side of the cover that projects toward the heater with a gap between it and the deodorizing body, and this reflective part reflects the heat radiated from the heater toward the deodorizing body.・Because the deodorizing body is set in the direction of It is possible to efficiently desorb and oxidize decomposition of odor components, and since a predetermined gap is secured between the reflecting part and the deodorizing body, the air containing odor components and the deodorizing body can be separated. This has an excellent effect in that the contact area is large and the absorption efficiency of odor components is also good.
