Refrigerator control method, controller and refrigerator

Abstract

The invention provides a refrigerator control method, a controller and a refrigerator. The refrigerator control method is used for controlling the air-cooled refrigerator, the air-cooled refrigeratorcomprises a refrigerating chamber and a freezing chamber, and a compressor and a draught fan are installed in the freezing chamber. The method comprises the steps that after the refrigerator is powered on, the current environment temperature is detected, and if the current environment temperature is higher than or equal to a first temperature threshold value, the freezing temperature of the freezing chamber is detected; and if the freezing temperature of the freezing chamber is higher than or equal to a second temperature threshold value, the compressor is controlled to be started up, and thedraught fan is controlled to be started up after being delayed for a first time period relative to the compressor. According to the refrigerator control method, the problem that the system load of theair-cooled refrigerator is high under the high environment temperature during an initial start and does not facilitate normal start of the compressor can be solved.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a refrigerator control method, a controller and a refrigerator. Background technique [0002] When the air-cooled refrigerator is initially started at high ambient temperature, the system load is heavy, which is not conducive to the normal start of the compressor. see figure 1 , this is because after the compressor is started, according to the existing control rules, the fan will also start to rotate, but at this time the temperature in the refrigerator compartment is the same as the ambient temperature, and the entire refrigeration system is still in an unbalanced state. The pressure on both sides can reach 15kg, and the refrigerant in the evaporator is in a high-temperature gas state. Coupled with the circulation of the fan, the rapid evaporation of the refrigerant in the evaporator is accelerated, resulting in an increase in system pressure. [0003] In additio...
