Defrosting refrigerator and control method thereof

Abstract

The invention provides a defrosting refrigerator and a control method thereof. The defrosting refrigerator comprises a box body, an air channel cover plate, door bodies, an evaporator, a defrosting sensor, a compressor, a fan and a controller. The air channel cover plate is arranged in the box body so as to limit a compartment and an air channel between the air channel cover plate and the inner back wall of the box body. The defrosting sensor is arranged on the evaporator and is used for detecting the temperature of the evaporator. The fan is arranged in the air channel and is used for circulating air between the air channel and the compartment. The controller is respectively connected with the defrosting sensor, the compressor and the fan and is used for controlling the compressor to stop running and controlling the fan to continuously run till the temperature detected by the defrosting sensor is up to a first temperature after the compressor runs preset starting and closing circles every time. According to the defrosting refrigerator disclosed by the embodiment of the invention, the inner space of the refrigerator is saved, the whole machine cost is reduced, and the energy consumption is also reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment design and manufacture, in particular to a defrosting refrigerator and a control method for the defrosting refrigerator. Background technique [0002] Along with the raising of people's living standard, refrigeration equipment such as refrigerator has become the necessity of people's daily life. Among them, the refrigerator using the frost-free system is favored by more and more consumers because of its advantages such as uniform temperature, fast cooling speed and automatic defrosting. [0003] Traditional refrigerators using a frost-free system generally use fans to achieve forced convection circulation of cold air to indirectly cool food. During the cooling operation, the surface temperature of the evaporator is lower than the dew point temperature of the air in the box, and the air continuously circulates in the refrigerator, and frost will form on the surface of the evaporato...

AI Technical Summary

Problems solved by technology

[0004] The defrosting device not only occupies the internal space of the refrigerator, but also increases the overall cost of the refrigerator; and because the heater needs to be energized during the defrosting process, it will increase the energy consumption of the refrigerator by 5% to 10%. Higher, there are potential safety hazards for refrigerators using flammable refrigerants such as R600a
