Automatic refrigerator deodorization control system based on polyharmonic vibration trigger circuit

Abstract

The invention discloses a refrigerator automatic deodorization control system based on a multi-harmonic vibration trigger circuit, which is characterized in that it mainly consists of a processing chip U2, a diode rectifier U1, a gas sensor QM, a transformer T, a triode VT1, a polar capacitor C1, Inductor L1, Zener diode D2, polar capacitor C3, polar capacitor C9, anti-interference circuit, triode voltage regulator circuit, second-order filter connected in series between the positive pole of polar capacitor C1 and the IN pin of processing chip U2 circuit, and a multi-vibration trigger circuit connected in series between the anti-jamming circuit and the same-named end of the primary side inductance coil of the transformer T. The present invention can automatically sterilize, disinfect and deodorize the refrigerator according to the concentration of peculiar smell in the refrigerator detected by the gas sensor QM, thus ensuring that the present invention can effectively eliminate the peculiar smell in the refrigerator and effectively suppress the odor of vegetables or fruits internal biochemical reactions.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an automatic deodorization control system for a refrigerator based on a multi-harmonic vibration trigger circuit. Background technique [0002] The traditional refrigerator uses the porous adsorption of activated carbon to absorb the peculiar smell in the refrigerator, but this deodorization method has no bactericidal effect, and the activated carbon needs to be replaced frequently, so it is very inconvenient to use. With the development of science and technology, people began to use ozone instead of activated carbon to deodorize refrigerators. Ozone can not only sterilize and disinfect the refrigerator, but also inhibit the biochemical reaction inside the vegetables or fruits, and play a certain role in keeping fresh. [0003] At present, when the refrigerator door is opened, the light in the refrigerator is irradiated on the photoelectric receiving tube to control the corona dischar...
