The invention discloses a refrigerator deodorization automatic control system with current buffer protection processing, which is characterized in that it mainly consists of a processing chip U2, a current buffer protection circuit, a diode rectifier U1, a gas sensor QM, a transformer T, a triode VT1, a pole polar capacitor C1, inductor L1, Zener diode D2, polar capacitor C3, polar capacitor C9, anti-interference circuit, and a second-order filter circuit connected in series between the positive pole of the polar capacitor C1 and the IN pin of the processing chip U2 , 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, thereby 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 a control system for deodorizing a refrigerator, specifically, an automatic control system for deodorizing a refrigerator with current buffer protection treatment. 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 ...
