Automatic door opening washing machines are generally provided with overload protection, usually by means of mechanical clutching, electromagnetic clutching or preset current threshold control. In the case of such an arrangement of overload protection, once the washer door is pushed or locked, it is not possible to try to push the door open again. If the door is jacked or locked for many times, the self mechanism of the automatic door opening device is easy to damage, so that the automatic door opening device fails, and even the door can not be opened or closed manually.

Based on this, the control portion 23 in the automatic door opening assembly 2 provided in the embodiment of the present application is further configured to: when a signal that the door panel 11 of the washing machine cannot be ejected by the ejection mechanism 22 is received, the ejection mechanism 22 is controlled to execute the door ejecting operation again in response to the signal, so that when the door panel 11 of the washing machine is ejected or locked, the door can be ejected by multiple attempts, and the operation of a user is facilitated. Or when a signal that the door plate of the washing machine is blocked or the automatic door opening assembly is nearly blocked or jammed is received, the ejection mechanism 22 is controlled to retract automatically, so that system noise caused by the door plate of the washing machine is avoided.

There are various detection modes for detecting whether the ejection mechanism 22 ejects the door panel 11 of the washing machine, and the application is not limited to this. As an example, as shown in fig. 1, the automatic door opening assembly 2 may further include a position trigger 25 and a corresponding position sensor 26. In some embodiments, the position trigger 25 may be mounted on the plunger 223 to facilitate accurate detection of the position of the plunger 223.
