Anti-freezing control method and device for refrigerator air door, controller and refrigerator

Abstract

The invention relates to an anti-freezing control method and device for a refrigerator air door, a controller and a refrigerator. The method comprises the steps that the target refrigeration temperature, set by a user, of a refrigerator chamber is obtained, and whether a preset continuous heating mode is executed or not is judged according to the target refrigeration temperature; if the continuousheating mode is executed, a heating component arranged on the refrigerator air door is controlled to continuously work for set time, and the refrigerator air door is heated; and otherwise, the on-offrate of the heating component is determined according to the obtained humidity of the position of the refrigerator air door, so that the refrigerator air door is heated according to a preset intermittent heating mode. According to the method, whether the heating component needs to be continuously heated or not is judged through the target refrigeration temperature, meanwhile, when the heating component does not need to be continuously heated, the on-off rate of the heating component is determined according to the humidity near the refrigerator air door, so that the air door anti-freezing phenomenon caused by air door condensation is avoided, the refrigerator energy consumption is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerator dampers, in particular to an anti-freezing control method, device, controller and refrigerator for refrigerator dampers. Background technique [0002] With the continuous change of refrigerator users' needs, the subsequent functions of refrigerators are also becoming more and more abundant. In order to meet the different storage purposes of users, the current refrigerator will have multiple compartments, and the temperature of each compartment is different. Each room decides whether to cool or not according to the needs of users. When the temperature requirements of each room are different, the temperature of each room is controlled through the refrigerator damper. The temperature control of the damper of the refrigerator is mainly realized by the damper motor, and the operation of the damper motor can adjust the flow of cold air, thereby realizing the control of the temperature of the comp...

AI Technical Summary

Problems solved by technology

The method of punching holes on the refrigerator damper, due to the difference in room temperature, the working conditions of the refrigerator damper are different, which leads to different degrees of freezing of the refrigerator damper, and the holes on the refrigerator damper alone cannot effectively solve the different degrees of refrigerator damper freezing Phenomenon, so the effectiveness of this antifreeze method is low

Using the heater to prevent the refrigerator damper from freezing, although it can have a better anti-freeze effect, but the heater will always be in the working state during the operation of the refrigerator. This method will lead to a large energy consumption of the refrigerator, resulting in poor user experience. Impact
