Problems solved by technology

Therefore, in addition to the moisture content of the food, another important reason for frosting in the refrigerator is the number of times the refrigerator door is opened. Therefore, the traditional pure cumulative time defrosting mode cannot perform intelligent defrosting in a targeted manner.

Abstract

The invention relates to a defrosting control system for a door switch counting refrigerator, which comprises a thermostat (theta1), a thermostat (theta2), a heater (H1), a compressor (CM), a fan (M), an illuminating lamp (L), a door switch (K) and a fuse (F), and also comprises an integrated electronic counting timer (6), wherein a pin (3) on the power end of the integrated electronic counting timer (6) is connected with a power supply through the thermostat (theta1); a pin (2) on the defrosting output end is connected with the fuse (F) and the heater (H1) through the thermostat (theta2); a pin (4) on the output end is respectively connected with the fan (M) and the compressor (CM); a pin (1) on the defrosting detection end is respectively connected with the thermostat (theta2) and a fuse (5); and a pin (5) on the detection end of the door switch is connected with the illuminating lamp (L) and one end of the door switch (K), and the other end of the door switch (K) is connected with the power supply. The defrosting control method is to increase the door opening frequency of the refrigerator and perform defrosting control on the wind-cooled refrigerator on the basis of the prior pure accumulated time defrosting mode.

Description

technical field [0001] The invention relates to the technical field of refrigerator defrosting control methods, in particular to a refrigerator defrosting control system counted by door switches, and also includes the defrosting control method of the control system. technical background [0002] Refrigerators are usually refrigerated by evaporating cooling capacity through the evaporator. In order to achieve a suitable temperature inside the refrigerator, the evaporator itself must be below 0°C. Therefore, during the cooling process, the moisture in the air will condense into frost on the surface of the evaporator. . Frost-free refrigerators are generally equipped with a fan near the evaporator, which uses the fan to blow air to generate circular convection in a closed environment, and is equipped with a small heating device to periodically defrost the frost. Therefore, the cooling speed of the refrigerator compartment of the air-cooled refrigerator is fast, and the tempera...
