Negative air ion deodorizing device for electric refrigerator

Abstract

The invention provides a negative air ion deodorizing device for an electric refrigerator. The negative air ion deodorizing device comprises a half-wave rectifying circuit, a 12 V direct-current voltage stabilizing power supply, a light-sensitive circuit, a monostability delay circuit and a negative ion generator circuit, and is characterized in that the selected type of a time base circuit IC1 in the monostability delay circuit is NE555. According to the negative air ion deodorizing device, air is ionized by high-voltage corona discharge to generate a large amount of negative air ions and a small amount of ozone, the negative air ions and the ozone are diffused and can be used for quickly removing odor in the electric refrigerator so as to keep original flavor of food in the electric refrigerator and prevent the food from being tainted by other odor; meanwhile, the ozone is a strong oxidant with very powerful functions of sterilization and disinfection, while negative oxygen ions can be also used for inhibiting biochemical process in vegetables and fruits so as to keep the vegetables and the fruits fresh to a certain extent; the original circuit layout of the electric refrigerator does not need to be changed when the negative air ion deodorizing device is mounted; and the circuits have the advantages of simplicity, convenience for use, very low power consumption and the like.

Description

technical field [0001] The invention belongs to the technical field of electronics and air purification, and relates to an air negative ion deodorization device for a refrigerator. Background technique [0002] The "deodorization" of refrigerators mostly uses the porous adsorption of activated carbon to absorb the peculiar smell in the refrigerator. This deodorizing method has only deodorizing effect, but cannot sterilize, and requires frequent replacement of activated carbon or the whole deodorizing finished product, which is inconvenient to use and increases economic expenditure. The negative air ion deodorizing device for refrigerators of the present invention is an electronic deodorizing device that can automatically remove peculiar smells in the refrigerator. It utilizes high-voltage corona discharge to ionize the air to produce a large amount of negative air ions and a small amount of ozone, which can quickly Remove the odor in the refrigerator, so as to maintain the ...
