Double-coil automatic door opening lock and washing machine with same

Abstract

The invention provides a double-coil automatic door opening and locking lock and a washing machine with the double-coil automatic door opening and locking lock, and belongs to the technical field of door locks. The double-coil automatic door opening and locking lock comprises a cam, a sliding block, an unlocking operation piece, an operation elastic piece and a lock catch; the unlocking operation part is provided with a limiting structure used for being matched with a lock catch, and the unlocking operation part has a protruding state after sliding in the unlocking direction of the lock catch on the sliding block. According to the double-coil door lock capable of opening the door automatically, the lock catch is hooked on the limiting structure of the unlocking operation piece so as to lock the sliding block, when unlocking is conducted by pulling the lock catch, the unlocking operation piece on the sliding block firstly moves by a certain distance along with the lock catch so that it can be guaranteed that an electromagnetic mechanism used for driving the lock catch can obtain the initial speed, and then the unlocking operation piece moves by a certain distance along with the lock catch; therefore, the lock catch is smoothly separated from the limiting structure.

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 automatic door lock is a door lock that can be controlled by an electromagnetic coil, so that the locking part in the door lock automatically unhooks the door hook to unlock the door lock. The automatic door lock is usually used on the door of a fully automatic washing machine. [0003] The automatic door lock of the prior art generally adopts a cam to lock the door hook, and then restricts the rotation of the cam through the lock catch. When the door hook needs to be unlocked, the electromagnetic mechanism controls the lock catch to unlock the action, so that the cam turns over under the action of the elastic member to unlock the door hook. [0004] However, when the cam is in the locked state, due to the large tension between the lock and the limiting structure, when t...

Problems solved by technology

[0004] However, when the cam is in the locked state, due to the large tension between the lock and the limiting structure, when the lock is moved and unlocked by the electromagnetic mechanism, it is necessary to overcome the large friction force, and even the problem of the cable being stuck
