Air cooling refrigerator and defrosting control method thereof

Abstract

The embodiment of the invention provides an air cooling refrigerator and a defrosting control method thereof, and relates to the field of refrigerator control, wherein refrigerator defrosting can be achieved in a more labor-saving manner. The air cooling refrigerator comprises a freezing chamber and a cold storage chamber which achieve heat isolation through a heat insulation partition plate, an evaporator chamber used for providing the cooling capacity for the freezing chamber and the cold storage chamber, a freezing air flue and a cold storage air flue. The evaporator chamber is located in the freezing chamber and internally provided with an electric heater and a temperature sensor. The freezing air flue is used for transmitting the cooling capacity in the evaporator chamber to the freezing chamber, and the cold storage air flue is used for transmitting the cooling capacity in the evaporator chamber to the cold storage chamber. The evaporator chamber and the cold storage air flue are isolated or communicate with each other through a first air door. The freezing air flue and the evaporator chamber communicate with each other through a freezing air inlet, the storage space of the freezing chamber communicates with the evaporator chamber through a freezing air return port, and the freezing air inlet is provided with a second air door.

Description

technical field [0001] The embodiments of the present invention relate to the field of refrigerator control, in particular to an air-cooled refrigerator and a defrosting control method thereof. Background technique [0002] At present, the defrosting method of air-cooled refrigerators is to start the defrosting program after the compressor has been working for a certain period of time, turn on the electric heater installed on the evaporator and then defrost by heating. When the evaporator is heated to a certain temperature Then exit the defrosting, the temperature in the box will rise significantly at this time, but because the cooling needs to continue after the defrosting is over, it needs to consume electric energy to lower the temperature again, and the additional time generated during the defrosting and defrosting recovery period Power consumption accounts for 10-20% of the power consumption of air-cooled refrigerators. This defrosting method greatly increases the extra...

[0002] At present, the defrosting method of air-cooled refrigerators is to start the defrosting program after the compressor has been working for a certain period of time, turn on the electric heater installed on the evaporator and then defrost by heating. When the evaporator is heated to a certain temperature Then exit the defrosting, the temperature in the box will rise significantly at this time, but because the cooling needs to continue after the defrosting is over, it needs to consume electric energy to lower the temperature again, and the additional time generated during the defrosting and defrosting recovery period Power consumption accounts for 10-20% of the power consumption of air-cooled refrigerators. This defrosting method greatly increases the extra energy consumption of the refrigerator. How to save energy after defrosting is an important research direction in the field of refrigerator control.
