Title:
CONTROL METHOD FOR REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2022/142688
Kind Code:
A1
Abstract:
A control method for a refrigerator which comprises a door body and an opening/closing mechanism for driving the reciprocating rotation of the door body between an open position and a closed position, the opening/closing mechanism comprising an ejector rod and a guide rod, the ejector rod being configured to be controlled to extend outward to open the door body, and the guide rod being configured to be controlled to move to drive the door body to rotate. The control method comprises: determining that the door body is in the closed position; acquiring a door opening signal of the refrigerator; controlling the ejector rod to extend outward to open the door body, and measuring a pivot angle of the door body relative to the closed position; determining whether the pivot angle of the door body relative to the closed position is greater than a preset first angle threshold; and if so, controlling the guide rod to move to drive the door body to rotate to the open position. In the present invention, the ejector rod and the guide rod are integrated into the opening/closing mechanism, and by means of controlling the ejector rod and the guide rod of the opening/closing mechanism, the integrated opening/closing mechanism is used to improve the method for opening/closing a door body of a refrigerator, so as to improve the degree of automation of opening/closing the door body on the premise of simplifying the structure of the opening/closing mechanism.
