Abstract: PROBLEM TO BE SOLVED: To obtain a high performance deodorizing antibacterial apparatus which is inexpensive, has a simple mechanism, and does not need maintenance for a long period by driving a fan for supplying air to a deodorizing antibacterial catalyst consisting of manganese dioxide, metal oxide, etc. SOLUTION: In an air passage 21 for circulating air in a refrigerator, air is introduced from an air suction port 22 and discharged from an air discharge opening 23, and a fan 24 is driven by a driving device 25. A deodorizing antibacterial catalyst 30 is set in the passage 21. The catalyst 30 is composed at least of manganese dioxide, oxide of copper, iron, etc., active carbon, zeolite, and a binder. When air containing offensive odor components is passed through the catalyst 30 by the fan 24, the components are adsorbed first by active carbon and zeolite to be deodorized promptly by the catalytic action, and bacteria are removed simultaneously. In this way, deodorizing and antibacterial effects can be attained very simply.

Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain an excellent deodorization effect on dimethyl sulfide by incorporating β type zeolite into a deodorant. SOLUTION: A deodorizing device comprises a nichrome wire 1 as a heating element and a catalyst coating layer 3 contg. the β type zeolite formed on the surface of this heating element. As a result, the air contg. malodorous components comes into contact with the catalyst coating layer 3 and absorbs the malodorous materials in the β type zeolite of the catalyst layer 3 when the nichrome wire 1 does not generate heat. The precious metal in the catalyst layer 3 is heated to its activation temp. and the malodorous components adsorbed thus far in the β type zeolite is made odorless and are released into the atmosphere when the nichrome wire generates heat. Simultaneously, the adsorption capability of the β type zeolite is regenerated. The β type zeolite has the excellent adsorbability to the dimethyl sulfide and, therefore, the βtype zeolite is capable of exhibiting the excellent deodorization effect on the dimethyl sulfide.

Abstract: PROBLEM TO BE SOLVED: To effectually adsorb, decompose, and deodrize all odor components by covering a heat production part of a glass pipe or a metal pipe heater with a catalyst layer having a specific composition. SOLUTION: This deodorizing heater 33 having a catalyst covering layer 37 on an effective heat production part surface of a glass pipe heater 36 is disposed below a condenser of a refrigerator. The catalyst covering layer 37 is constructed by forming a metal oxide or copper oxide such as manganese dioxide, a perovskite type metal oxide, hexaaluminate, a catalyst material such as alumina carrying platinum metal, and an adsorbent such as zeolite using a coupler such as aluminum hydroxide, alumina zol, and silica gel. In a cooling operation, air containing odor components passing through the inside of a condenser chamber touches the deodrizing heater 33 to permit the odor components to be adsorbed into the catalyst covering layer 37 and be removed. The construction is simple, an instlalation space is reduced, and all odor components including neutral odor components such as acetaldehyde are effectually adsorbed, decomposed, and deodrized.

Abstract: PURPOSE:To remove an odor in a room completely and simply over a long period of time by forming a catalyst layer containing active alumina, silica, and platinum group metal on a glass film. CONSTITUTION:Air containing odor components which passed through a heat exchanger is contacted with a catalyst layer 18 of a deodorization apparatus 10 so that the odor components in a room are adsorbed by active alumina and zeolite in the catalyst layer 18. On the other hand, when a turn-on signal is output from a control circuit to the deodorization apparatus 10, a resistance wire 19 generates heat to heat a metal tube 15 so that the odor components adsorbed by the active alumina and the zeolite in the catalyst layer 18 is oxidized by the catalytic function of the platinum group metal to be decomposed into odorless compounds. The active alumina and the zeolite heated by the metal tube 15 recover their adsorption power because of the elimination of the adsorbed odor components to be able to repeat the adsorption of the odor components. By repeating alternately the adsorption of the odor components during non-heating and the catalytic decomposition of the odor components during heating, the odor can be removed continuously over a long period of time.
