本発明は、冷蔵庫等の庫内の空気に含まれる臭気或分を
除去するための冷蔵庫等の脱臭装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a deodorizing device for a refrigerator or the like for removing a certain amount of odor contained in the air inside the refrigerator or the like.

て分解除去するようにしたものがある。(Prior Art) Conventionally, deodorizing devices for refrigerators and the like have used adsorbents such as activated carbon to adsorb and remove odor components contained in the air inside the refrigerator. Equipped with an ozone generator and a catalyst, the ozone generated from the ozone generator is reacted with odor components in the air inside the refrigerator, the odor components are removed by oxidation decomposition, and the remaining ozone is decomposed and removed by the catalyst. There is something.
しかしながら、これらのもののうち吸着剤を用いたもの
は、吸着剤により臭気或分を吸着するのみであり、吸着

要があり、全体として構造が複雑であるという欠点があ
る。However, among these products, those that use an adsorbent only adsorb a certain amount of odor, and once the adsorption capacity of the adsorbent is saturated, no more odor components can be adsorbed, so the life of the deodorizing function is shortened. It has the disadvantage of being short. On the other hand, those using an ozone generator have the disadvantage that not only the ozone generator is required, but also the remaining ozone that is harmful to the human body must be decomposed, and the overall structure is complicated.

したものを提案している（例えば、実願昭６３−２２２
０９号、または実願昭６３−２３５２８号参照）。In order to eliminate these drawbacks, the present applicant has developed a structure that includes a deodorizing body having an adsorbent layer and a catalyst layer, and a heater that heats the deodorizing body under power-on/off control. We have proposed a method in which the odor components are adsorbed by the adsorbent layer, the adsorbed odor components are desorbed by the adsorbent layer by heating with a heater, and the desorbed odor components are oxidized and decomposed in the catalyst layer ( For example, Jitsugan Sho 63-222
No. 09 or Utility Model Application No. 63-23528).
このものによれば、脱臭体の吸着剤層は臭気或分を脱着
することにより吸着機能、即ち脱臭機能が再生されるか
ら、脱臭機能の寿命を長くできる。According to this, the adsorbent layer of the deodorizing body regenerates the adsorption function, that is, the deodorizing function, by desorbing a certain amount of odor, so that the life of the deodorizing function can be extended.
また、脱臭体とヒータとにより構成されるものであるか
ら、構造も簡単である。Furthermore, since it is composed of a deodorizing body and a heater, the structure is simple.

Therefore, there is a problem to be solved that the decomposition efficiency of odor components is low.

It is possible to heat the surface of the deodorizing body as uniformly as possible by transmitting the heat to the body and heating it.

うという問題点が生ずる。However, when the wire mesh covering the deodorizing body is brought into contact with the heater, the deodorizing body and the heater are in contact with each other through the wire mesh, so the air flow is obstructed at the contact area, and the surface of the deodorizing body is A problem arises in that the flow of air in the vicinity deteriorates, and as a result, the adsorption efficiency of a certain amount of odor by the deodorizing body decreases.

着効率が良い。Now, in the above structure, during the cooling operation of the refrigerator, the air inside the refrigerator is circulated through the cooler chamber 7, the freezer chamber 2, and the return duct 10 by the blowing action of the fan 8, and the air inside the refrigerator is circulated through the cooler chamber 7, It is circulated through the supply duct 11, the refrigerator compartment 3, and the return duct 10. In this process, the air passing through the cooler chamber 7 passes through the holes in the wire mesh 18 to the deodorizing body 15.
The odor components contained in the air are adsorbed by the adsorbent layer 15a of the deodorizing body 15 and removed. At this time, since air also flows well into the space 20 between the deodorizing body 15 and the heater 13, a good flow of air near the surface of the deodorizing body 15 can be ensured, and the adsorption efficiency of odor components by the deodorizing body 15 is increased. is good.

再生される。On the other hand, when the cumulative operating time of a compressor (not shown) reaches a predetermined value, the compressor and fan 8 are turned off, while the heater 13 is turned on and defrosting operation of the cooler 6 is started. The heat generated by the heater 13 heats the cooler 6 to perform defrosting, and at the same time, the deodorizing body 15 is heated. At this time, since the surface of the deodorizing body 15 is covered with the wire mesh 18, the heat conduction of the wire mesh 18 causes the deodorizing body 15 to
will be heated as evenly as possible. When the deodorizing body 15 reaches a predetermined temperature or higher due to heating, the adsorbent layer 15a
The odor components adsorbed in the catalyst layer 15b are desorbed, and together with this, the odor components are oxidized and decomposed and removed in the catalyst layer 15b. The deodorizing body 15 is heated in this manner and desorbs odor components, thereby regenerating its adsorption function, that is, its deodorizing function.

ようになる。When the temperature of the cooler 6 reaches a predetermined defrosting end temperature or higher, the heater 13 is cut off and the defrosting operation is ended, and then the compressor and the fan 8 are energized and the cooling operation is restarted again. . Along with this, the temperature of the deodorizing body 15 also decreases, and the deodorizing body 15 comes to adsorb odor components in the same manner as described above.

向上を図るこεができる。According to the embodiment described above, the surface of the deodorizing body 15 is
Since the wire mesh 18 is covered with a metal mesh and brought into contact with the heater 13, the surface of the deodorizing body 15 can be heated as uniformly as possible by the heat conduction of the wire mesh 18, thereby efficiently desorbing and oxidizing decomposition of odor components by the deodorizing body 15. It can be carried out. Further, even if the deodorizing body 15 should be damaged, the wire mesh 18 can prevent the deodorizing body 18 from scattering and falling. Moreover, one convex portion formed on the wire mesh 18 allows the deodorizing body 15 and the heater 13 to be connected to each other.
Since the space 20 is secured between the deodorizer 15 and the deodorizer 15, a good flow of air can be ensured in the vicinity of the surface of the deodorizer 15, thereby improving the adsorption efficiency of odor components by the deodorizer 15. I can do it.
