Control circuit of ozone generator for refrigerator

Abstract

The invention discloses a control circuit of an ozone generator for a refrigerator. The control circuit comprises a main controller, a feedback circuit, a switch control circuit and a power supply control circuit; a signal input end of the feedback circuit is used for connecting a feedback signal output end of the ozone generator, and a signal output end of the feedback circuit is connected with afeedback signal input end of the main controller; the input end of the switch control circuit is connected with a switch signal output end of the main controller, and the output end of the switch control circuit is connected with a switch signal input end of the ozone generator; a power supply control signal input end of the power supply control circuit is connected with a power supply control signal output end of the main controller, and a power supply output end of the power supply control circuit is connected with a power supply input end of the ozone generator. The circuit can detect theworking condition of the ozone generator in real time, effectively save the power consumed by the refrigerator, and greatly reduce the standby power consumption of the ozone generator when not preparing ozone.

Description

technical field [0001] The invention relates to the field of intelligent household appliances, in particular to a control circuit of an ozone generator for a refrigerator. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, refrigerators have entered thousands of households and become indispensable household appliances for daily life. A refrigerator is a device that creates a low-temperature environment to preserve food. Early refrigerators did not have antibacterial, sterilizing and deodorizing functions, and only relied on low temperature to protect food, which was not conducive to long-term preservation of food in the refrigerator and food in the cold room. In order to solve this problem, an ozone generator is currently used in the refrigerator to sterilize. [0003] When the ozone generator in the existing refrigerator is not producing ozone, it still has a large standby power consumption. In or...
