Control manner of refrigerator

Abstract

The invention provides a control method of a refrigerator. The control method comprises the steps that opening and closing state information of a refrigerating door and defrosting state information of the refrigerator are obtained; and when the refrigerating door is in the open state and the refrigerator is in the defrosting state, an air duct assembly stops guiding air into a refrigerating chamber, an air curtain assembly is started, and an air curtain is formed at the front end of the refrigerating chamber. When the refrigerator is in the defrosting state, the air duct assembly stops guiding air into the refrigerating chamber, so that heat in the air duct assembly is prevented from being guided into the refrigerating chamber. After the refrigerating chamber is opened, the air curtain assembly is started, the air curtain assembly extracts air in the refrigerating chamber, and after the air in the refrigerating chamber is acted by the air curtain assembly, an air curtain is formed at the front end of the refrigerating chamber. During defrosting, the air curtain assembly forms an air curtain at the front end of the refrigerating chamber through cold air in the refrigerating chamber, so that air inside and outside the refrigerating chamber is isolated, the effective air curtain is formed at the front end of the refrigerating chamber, and the storage temperature of the refrigerating chamber is kept.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a control method for a refrigerator. Background technique [0002] Air curtain, also known as air curtain, is mainly used above the entrances of shopping malls, theaters, hotels, restaurants, etc. for refrigeration, air conditioning, dustproof, and heat insulation. It can isolate indoor and outdoor air and prevent indoor and outdoor air from exchanging heat and cold. Anti-dust, anti-pollution, anti-mosquito and fly. [0003] For air-cooled refrigerator products, according to the existing test: when the ambient temperature is 30°C, if the door of the refrigerator is opened for 10 seconds, the temperature inside the box will rise by 5°C-6°C; if it is opened for 1-2 minutes, the temperature inside the box will drop will reach the ambient temperature. After closing the refrigerator door, if the room temperature returns to the set temperature, the compressor must continue to r...

AI Technical Summary

Problems solved by technology

When the refrigerator defrosts, the temperature in the air duct assembly rises. At this time, after the refrigerator compartment is opened, if the air in the air duct assembly is used to form an air curtain in the refrigerator compartment, the temperature of the air coming out of the air duct assembly is relatively high. , the temperature of the air curtain at the front of the refrigerator will cause the temperature of the refrigerator to rise rapidly, so that an effective air curtain cannot be formed at the front of the refrigerator, and the storage temperature of the refrigerator cannot be effectively maintained.
