Abstract

The invention provides a method for controlling the pressure balance of a refrigerator. The refrigerator includes a compartment, a door body for opening or closing the compartment, a refrigeration system for providing cooling capacity to the compartment, an ice maker installed on the door body, and a The control device for the operation of the refrigerator. The refrigeration system also includes the cooling air path that transmits the cooling capacity to the compartment, the cooling fan and the first damper installed on the cooling air path, and the ice-making air path and equipment that transmits the cooling capacity to the ice machine. For the ice-making fan and the second air door of the ice-making air path, the door body is provided with an ice outlet for taking ice and an ice outlet cover set on the ice outlet. The control method includes the following steps: S1. Determine whether the refrigerator needs Perform decompression, if so, execute step S2; S2, open the first damper, the second damper and the ice outlet cover, and control the ice-making fan to reverse; S3, after the refrigeration fan reverses for a certain time t, control the ice-making fan to stop Reverse and close the ice outlet cover. In the case of no additional components, it is easy to open the door by balancing the pressure inside and outside the refrigerator.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a pressure balance control method of a refrigerator. Background technique [0002] With the improvement of the economic level, users have higher and higher requirements for refrigerators. In order to facilitate users to take ice cubes, the existing refrigerators are provided with an ice maker and an ice outlet on the door body, so that the cover on the door body can be opened. , the ice cubes can be taken directly. However, during the ice making process, the ice outlet cover is closed, the air door of the ice making machine 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 directed to the ice maker to make ice, and the cooling capacity in the box is conducted to the ice maker on the door body, so that the cooling capacity flowing to the compartment ...
