Temperature control equipment in use for full automatic mechanical refrigerator

Abstract

The invention provides a full automatic mechanical electric refrigerator temperature controller, composed of power supply unit, executing unit, control unit, signal input unit, refrigerating chamber temperature sensor and refrigerate-evaporating temperature sensor. Its characteristic: the power supply unit converts the 220v AC electric supply to +12V and +5V DC power supplies, where the +12V power supply supplies the power to the executing unit; the +5V power supply supplies the power to the control unit and signal input unit, is converted to analogue voltage signal through the signal input unit and converted to digital signal through the control unit, and after analyzed and judged by the control unit, transfers to the executing unit to control the stop or delayed switching-on by starter for the compressor and the switching-on and -off of temperature compensator. It has simple structure, and the refrigerator temperature can automatically be regulated according to environmental temperature, remedying the defect that the existing refrigerator works in an unreasonable state because of temperature change.

Description

technical field [0001] The invention relates to a mechanical refrigerator, in particular to a fully automatic temperature control device for a mechanical refrigerator. Background technique [0002] There are basically two types of existing refrigerators, mechanical refrigerators and computer refrigerators. Mechanical refrigerators use a thermostat to control the start and stop of compressors; computer refrigerators use computer boards to operate according to user settings. Mechanical and computer refrigerators Computer refrigerators require people to set the temperature, and refrigerators with automatic temperature setting are generally high-end computer refrigerators, which are expensive and cannot be afforded by ordinary consumers. However, in the actual use of the refrigerator, according to statistics, 80% of people never change the set value according to the change of the ambient temperature, so that the refrigerator runs in an unreasonable state for part of the time. ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a method that can solve the problem of artificially adjusting the temperature setting value of existing mechanical refrigerators and low-end computer refrigerators, and prevent the refrigerator from running in an unreasonable state for a part of the time.
