Intermittent temperature controller of refrigerator

Abstract

The invention provides an intermittent temperature controller of a refrigerator. The controller is composed of a 220V AC power supply, a resistance-capacitance voltage reducing rectification circuit, a 12V voltage stabilizing circuit, an intermittent oscillating circuit, an intermittent time regulating circuit, a level power amplification and relay control circuit and a refrigerator working condition indication circuit. The controller is characterized in that the model number of a binary serial counting integrated circuit IC1 in the intermittent oscillating circuit is CD4060. Some refrigerators have the faults of failure in stopping, and so on, caused by poor performance of the temperature controller or slight leakage of the refrigerating fluid in the refrigerating system of the refrigerator. Such a fault has the following dangers that 1, a compressor of the refrigerator is tired and completely damaged after working long time without stop; 2, the compressor causes power waste by working without stop; and 3, fire risk exists in electricity utilization of the refrigerator. The intermittent temperature controller solves the problems in above aspects better without changing the original internal circuit structure of the refrigerator, effectively ensures safety utilization of electric power and prolongs the service life of the compressor of the refrigerator.

Description

technical field [0001] The invention belongs to the technical field of electronics and temperature control, and relates to an intermittent temperature controller for a refrigerator. Background technique [0002] The cabinet of the refrigerator is equipped with a temperature controller. After several years of use, some refrigerators may cause the compressor not to stop due to the poor performance of the temperature controller, or a slight leakage of the refrigerant in the refrigeration system of the refrigerator may also cause Non-stop and other failures. Although this kind of failure has little impact on the use, if it is not dealt with in time, the main hazards are: first, the refrigerator compressor will be fatigued and completely damaged after long-term operation without stopping; second, the long-term non-stop of the compressor will cause unnecessary damage Waste of electricity; Third, there is a fire hazard in the electricity used by the refrigerator. Because the volu...

[0002] The cabinet of the refrigerator is equipped with a temperature controller. After several years of use, some refrigerators may cause the compressor not to stop due to the poor performance of the temperature controller, or a slight leakage of the refrigerant in the refrigeration system of the refrigerator may also cause Non-stop and other failures

Although this kind of failure has little impact on the use, if it is not dealt with in time, the main hazards are: first, the refrigerator compressor will be fatigued and completely damaged after long-term operation without stopping; second, the long-term non-stop of the compressor will cause unnecessary damage Waste of electricity; Third, there is a fire hazard in the refrigerator

Due to the large volume and weight of the refrigerator, it is inconvenient for users to carry it up and down for maintenance in time
