Deodorization device

Abstract

The object of the present invention is to make a deodorizing device to efficiently remove an odorous component contained in a gas even in a closed space in which the gas is not circulated. This deodorizing device is constituted by providing a DC discharge mechanism 27, a photocatalyst module 28, and an ozonolysis catalyst filter 29 in a duct 26. The discharging mechanism 27 is constituted of a wire-like ignition electrode 30 and a pair of counter electrodes 31. The ignition electrode 30 is arranged by shifting the electrode 30 leftward from the lateral center line A of the counter electrodes 31. When a DC high-voltage potential is impressed upon the electrode 30, high-voltage discharge occurs between the electrodes 30 and 31 and an ion wind is generated, resulting in the generation of an air current flowing in the direction expressed by the arrow B in the duct 26. Consequently, the cold air in a refrigerator flows in the duct 26 from an inlet port 26a, is deodorized when the cold air passes through the photocatalyst module 28 and ozonolysis catalyst filter 29, and is discharged into the refrigerator from an outlet port 26b.

Description

technical field [0001] The present invention relates to a deodorizing device for deodorizing gas by removing odor components in the gas. Background technique [0002] For example, in a refrigerator, in order to reduce various odors caused by food in the refrigerator and to prevent the odor from affecting other foods, a deodorizing device composed of adsorbents such as activated carbon has always been used in the refrigerator. However, once the adsorption capacity of the adsorbent is saturated, the effect is lost, so it must be replaced appropriately. In addition, if left in a state where the adsorption capacity is saturated, there is also a problem that the odor is emitted again from the adsorbent itself on the contrary. [0003] As a method of prolonging the deodorization performance, the method adopted is to install a platinum catalyst near the defrosting heater to absorb the odorous substances contained in the air in the refrigerator, and use the heater to heat and decom...

Problems solved by technology

[0005] Therefore, for example, when the above-mentioned deodorizing device is applied to a direct-cooling refrigerator or a lower box in which cold air (gas) does not circulate in the refrigerator, a dedicated blower fan for the deodorizing device must be provided to make the gas flow in the deodorizing device. circulation, so there is a corresponding increase in the volume of the entire device

In addition, even in this type of refrigerator in which cold air is circulated by a blower fan, the location where the deodorizer is installed is limited to the circulation path of the cold air, so there is a problem that the degree of freedom in the installation of the deodorizer is low.

Also, when the blower fan stops and the air-conditioning does not circulate, the deodorizing efficiency will drop
