Abstract: PROBLEM TO BE SOLVED: To prevent falling of a deodorizing catalyst including falling of a powder and improve antibacterial function of the deodorizing catalyst itself by, in a low temperature activated deodorizing catalyst which oxidizes and decomposes odorous components in air in the presence of oxygen, applying an oxidizing agent, which oxidizes and decomposes odorous components added to a catalyst base material. SOLUTION: A low temperature activated deodorizing catalyst 7 has deodorizing performance and such function as to enhance surface strength of catalyst and vibration separation strength, and is composed of a catalyst base material 8 and a metal oxide applied to the material 8. And oxidizing agents 9 are scattered over the material 8 and glass fibers are kneaded into the material 8. Further, 5wt.% of copper is added to the catalyst 7 to oxidize and decompose odorous components. As a result, odorous components are prevented from penetrating into a low temperature activated catalyst but captured at the surface of the catalyst and decomposed. Therefor, deodorizing performance of the catalyst can be maintained and surface strength and vibration separation strength of the catalyst can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To maintain the antibacterial constitution concentration in a container constantly and to obtain a high antibacterial effect including air and food surface by arranging a sustained release film for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material at a part where a cool air passes in a refrigerator. SOLUTION: A sustained release film 12 for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material 1 at a point where a cool air passes inside a refrigerator. Then, an antibacterial constituent particle 11 is impregnated with a gel-shaped substance 2. Also, the amount of sustained release of the antibacterial constituent is increased against the temperature increase in a container due to the opening/closing of the door by the sustained release film made of a shape memory resin due to temperature, thus dispersing the antibacterial constituent into the refrigerator and constantly maintaining the antibacterial constituent concentration in the container, killing germs floating in air and germs being adhered to the surface of food, and hence achieving a high antibacterial effect.

Abstract: PROBLEM TO BE SOLVED: To contrive to upgrade the application effect of an air circulation duct and an air circulating fan by operating the air circulating fan during a routine operation when a compressor comes to a halt and providing a control device which executes operation for a definite time during quenching time. SOLUTION: When a quenching switch 37 is not turned on, a temperature determination means 36 in a freezer compartment determines whether or not the temperature in the freezer compartment 18 is higher or lower to an on/off setting temperature. When the freezer compartment temperature determination means 36 determines that the temperature in the freezer compartment is lower than the off setting temperature, the operation of a compressor 22 is halted with a compressor control means 40. When the compressor is halted, an air circulating fan 29 is operated by an air circulating fan control means 41. On one hand when the quenching switch 37 is turned on, the air circulating fan 29 is operated in continuous mode with the air circulating fan control means 41 irrespective of the operating state of the compressor 22. Therefore, this construction makes it possible to upgrade the application effect of the air circulating duct 28 and the air circulating fan 29.
