Pressure balance control method of refrigerator

Abstract

The invention provides a pressure balance control method of a refrigerator. The refrigerator comprises a chamber, a door body for opening or closing the chamber, a refrigerating system for providing cold energy to the chamber, an ice maker arranged on the door body and a control device used for controlling operation of the refrigerator. The refrigerating system further comprises a refrigerating air duct, a refrigerating fan, a first air door, an ice making air duct, an ice making fan and a second air door, wherein the refrigerating air duct is used for delivering cold energy to the chamber; the refrigerating fan and the first air door are arranged on the refrigerating air duct; the ice making air duct is used for conducting cold energy to the ice maker; and the ice making fan and the second air door are arranged on the ice making air duct. The door body is provided with an ice outlet used for taking ice and an ice outlet cover plate covering the ice outlet. The control method comprisesthe following steps of S1, judging whether the refrigerator needs to be decompressed or not, and if yes, executing the step S2; S2, opening the first air door, the second air door and the ice outletcover plate, and controlling the ice maker to rotate reversely; and S3, controlling the ice making fan to stop rotating reversely and closing the ice outlet cover plate after the refrigerating fan rotates reversely for a period of time t. Through the pressure balance control method of the refrigerator, under the condition of not adding components, the internal and external pressure of the refrigerator is balanced to facilitate door opening.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a pressure balance control method for a refrigerator. Background technique [0002] With the improvement of economic level, users have higher and higher requirements for refrigerators. In order to facilitate users to take ice cubes, existing refrigerators are equipped with ice machines and ice outlets on the door body, so that the cover plate on the door body can be opened. , you can take the ice cubes directly. However, during the ice making process, the ice outlet cover is closed, the air door of the ice machine air path is opened to make the ice making air path unblocked, and then the ice making fan is turned on to evaporate the refrigeration. The cooling capacity of the refrigerator is guided to the ice maker to realize ice making, and the cooling capacity in the box is transmitted to the ice maker on the door body, so that the cooling capacity flowing to the com...
