Refrigerating equipment, its defrosting control method, control device, and storage medium

Abstract

Embodiments of the present invention provide a refrigeration device, a defrosting control method, a control device, and a storage medium, which belong to the field of electric appliances. The refrigerating equipment includes a freezing chamber, and the freezing chamber is provided with an evaporator for cooling, a compartment temperature sensor for detecting the temperature of a compartment in the freezing chamber, and a defrosting temperature sensor for detecting the temperature of the evaporator, so The control method includes: when the freezing compartment is in a cooling state, determining a first drop range of the temperature of the compartment within a preset time period; and when the first drop range is smaller than a preset range and the evaporation When the temperature of the evaporator is lower than the preset temperature, an immediate defrosting operation is performed on the evaporator. Through the above technical solution, when the evaporator is full of frost or frost is blocked, the evaporator can be defrosted in time, so as to avoid affecting the normal use of the refrigeration equipment due to a large amount of frost on the evaporator.

Description

technical field [0001] The invention relates to the field of electric appliances, in particular to a refrigeration device, its defrosting control method, control device, and storage medium. Background technique [0002] At present, the air-cooled refrigerator generally judges whether to defrost the freezer according to the cumulative running time of the compressor. That is, when the accumulative running time of the compressor reaches the predetermined defrosting cycle, the defrosting operation for the freezing compartment starts. However, when the air-cooled refrigerator is used in a harsh environment, for example, the door of the freezer is often opened or there are foods with high moisture content in the freezer, a large amount of water vapor will enter the freezer and form on the evaporator. Frost. In this way, when the cumulative running time of the compressor has not reached the predetermined defrosting cycle, the evaporator may be full of frost or even blocked by fro...

However, when the air-cooled refrigerator is used in a harsh environment, for example, the door of the freezer is often opened or there are foods with high moisture content in the freezer, a large amount of water vapor will enter the freezer and form on the evaporator. Frost

In this way, when the cumulative running time of the compressor has not reached the predetermined defrosting cycle, the evaporator may be full of frost or even blocked by frost, which will cause the evaporator to fail to cool normally, seriously affecting the use of users
