Abstract

The invention discloses a control method for automatic door opening of a refrigerator, and relates to the technical field of household appliances. The control method comprises the following steps that after the refrigerator is powered on, a main control panel of the refrigerator monitors closing or opening of a door body; when the main control panel of the refrigerator receives a door opening signal, if the main control panel of the refrigerator monitors that the door body is in a closed state, operation enters the third step; if the main control panel of the refrigerator monitors that the door body is in an open state, an ejector rod mechanism does not act; the main control panel of the refrigerator performs power-off operation on an electromagnetic coil, and the suction force of a door seal disappears; and then the ejector rod mechanism is started, and the door body of the refrigerator is automatically pushed open by the ejector rod mechanism. By means of the control method, automatic door opening is achieved on the premise that the safety of users is guaranteed as much as possible when the door is opened; and according to the method, before the ejector rod mechanism is started, the suction force of the door seal disappears, that is, the ejector rod mechanism can easily push the door body open with relatively small force, noise is low, and it can be guaranteed that users are not hurt when the door is opened.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to a control method for automatically opening the door of a refrigerator. Background technique [0002] Most of the existing refrigerators are opened manually, which is very inconvenient when people take objects to open the door. Automatic door-opening refrigerators can solve these problems well. [0003] There is an open automatic door refrigerator at present, which realizes automatic door opening by means of a push rod mechanism. The principle of this method is mainly to overcome the suction force of the door seal through the push rod mechanism, and then push the door body completely open. For some large-capacity refrigerators, the door seal has a strong suction force. In order to overcome the suction force of the door seal, the ejector mechanism usually needs to increase its own ejection force to meet the door opening requirements. Although the door can be opened, ...
