Abstract

The double-coil automatic door lock and the washing machine with it provided by the present invention belong to the technical field of door locks, wherein the double-coil automatic door lock includes: a cam, a lock catch, a protective rod and two electromagnetic mechanisms, wherein the The first electromagnetic mechanism is used to drive the limit block to lock the protection bar in the first state, and the second electromagnetic mechanism is used to drive the lock to twist towards the unlocked state; the double coil automatic door opening of the present invention The lock has two electromagnetic mechanisms, which are respectively used to control the unlocking of the cam twice. When the first electromagnetic mechanism drives the limit block to unlock the protection rod, the protection rod can slide backwards, and then the second electromagnetic structure The action can cause the lock to release the locking of the cam. In the above process, it is necessary to send control signals to the two electromagnetic mechanisms respectively. When the door lock will not open, the user's safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a double-coil automatic door lock and a washing machine having the same. Background technique [0002] The door lock applied to the door of the washing machine generally adopts an automatic door lock at present, and its working principle is to use an electromagnetic coil to drive the lock to unlock the cam. [0003] When the existing automatic door lock is unlocked, an electromagnetic coil is used, and the cam can be unlocked by one action. [0004] However, in actual use, sometimes when using hot water for laundry, due to the high temperature in the washing machine, for safety reasons, after the washing machine stops working, it is necessary to wait for a period of time before opening the door. At this time, if the existing door opening method is adopted, opening the door directly may cause danger to the user. SUMMARY OF THE INVENTION [0005] Therefore, the technical pro...
