Refrigerator

Abstract

The objective of the invention is to provide a refrigerator that is structured such that even a plurality of purification function mechanisms are arranged in an cold air circulation path, the conditions that cooling performance decreases and the cost improves can not occur and the deodorizing and degerming performances can be improved. The refrigerator (1) performs a circulation using a mode of firstly supplying the cold air generated by a cooler (7) through to a refrigerating chamber (2) by a fan (8), thereafter returning to the cooler. A deodorizing and degerming device (18) with a plurality of purification function mechanisms (16), (17) is arranged in the cold air circulation path. The plurality of purification function mechanisms (16), (17) employ functional materials which have deodorizing and degerming or integrated performances on a support body with ventilation performance, which is characterized in that the multiple purification function mechanisms have deodorizing and degerming functions and inner air quantity different from one another, and the mechanisms are parallely installed relative to the cold air flow in the circulation path.

Description

technical field [0001] The present invention relates to a refrigerator in which a deodorizing and degerming device is arranged in a cold air circulation path to deodorize a storage room. Background technique [0002] In recent years, people's attention to food culture has increased, and the situation of storing food with various odors in household refrigerators has also increased. Therefore, in the past, in order to remove the odor and floating bacteria in the refrigerator, the purification function has been achieved by carrying an adsorbent such as activated carbon or a catalyst such as an oxide on an air-permeable support including honeycomb ceramics. The mechanism is placed in the cold air circulation path of the refrigerator to deodorize and sterilize bacteria. [0003] As for the odor in the refrigerator, as a result of gas chromatograph analysis by adsorbing the odor component on activated carbon, it is a complex odor of various odors such as aldehydes, fatty acids, a...

Problems solved by technology

[0011] In addition, for adsorption members such as activated carbon and decomposition catalysts such as oxides, under normal circumstances, the greater the air volume passing through the catalyst, the greater the removal of odor and planktonic bacteria per unit time. As far as the mechanism is concerned, the relationship between the adsorption and decomposition performance and the air volume is different for each part of the purification function mechanism. Therefore, if the air volume exceeds a certain amount, the removal performance will not be improved or the performance will be reduced. Therefore, it was expected Set the appropriate air volume according to the adsorption part or detachable part
