Electronic defrosting system having refrigerating chamber stopping function

Abstract

The invention discloses an electronic defrosting system having a refrigerating chamber stopping function, in which the starting and stopping states of a compressor and a fan motor are controlled via a control plate. The electronic defrosting system is characterized that a refrigerating chamber electronic temperature probe is arranged in a refrigerating chamber; the compressor and the fan motor are stopped by the control plate when the temperature in the refrigerating chamber is detected to reach a preset temperature by the refrigerating chamber electronic temperature probe; a defrosting loop consisting of a defrosting probe, a heater and a defrosting fuse is arranged on the control plate; and the heater and the defrosting fuse are controlled to be in an open circuit by the control plate when the defrosting probe detects that a preset value is reached. Through a low cost, the invention not only ensures the reliability of the refrigerator, but also ensures that the refrigerating temperature does not exceed zero while a refrigerating capability experiment.

Description

technical field [0001] The invention relates to a refrigerator defrosting system. Background technique [0002] At present, air-cooled refrigerators are becoming the theme and hot spot of development, and air-cooled refrigerators, as one of them, are attracting more and more attention. Generally, the current refrigerator control system adopts two methods: one is the electronic control method, and the other is the electronic control method. The advantages of one method are high control precision and good reliability, but the disadvantages are high cost, long design and development cycle, and high manufacturing process requirements; the other is the mechanical control method, which has low cost, short design and development cycle, and the disadvantage is control accuracy Low, poor reliability, and in the test of its freezing capacity, it often occurs that the refrigeration crosses zero, resulting in unqualified performance of the refrigerator.
