Embodiment 1

[0062] This embodiment provides a specific implementation of a double-coil automatic door lock, such as figure 1 As shown, it includes: a lock case 1 , and the lock case 1 has a first electromagnetic mechanism 2 , a second electromagnetic mechanism 3 , a cam 4 , a lock catch 5 and a protection rod 6 . Wherein, the cam 4 is connected in the lock housing 1 for rotation, and the lock buckle 5 is connected in the lock housing 1 so that it can be twisted left and right relative to the rotation surface of the cam 4, and the left and right twist is figure 1 Indicates the direction of the arrow on the lock 5; the lock 5 has a locking state that is connected to the cam 4 after being twisted toward the direction close to the cam 4, and the lock 5 also has a direction away from the cam 4. In the unlocked state where the connection with the cam 4 is disconnected after the direction is twisted, when the second iron core 7 in the second electromagnetic mechanism 3 moves, the lock catch 5 ca...

Embodiment 2

[0083] This embodiment provides a washing machine, the door lock of which adopts the double-coil automatic door lock described in Embodiment 1.

Abstract

The invention provides a dual-coil automatic opening door lock and a washing machine provided with the same, and belongs to the technical field of door locks. Specifically, the dual-coil automatic opening door lock comprises a cam, a lock catch, a protective rod and two electromagnetic mechanisms, wherein a first electromagnetic mechanism is used for driving a limiting block to lock the protectiverod in a first status and a second electromagnetic mechanism is used for driving the lock catch to twist towards an unlocked status. The dual-coil automatic opening door lock is provided with the twoelectromagnetic mechanisms which are used for controlling two times of unlocking of the cam respectively. When the first electromagnetic mechanism drives the limiting block to release the locking ofthe protective rod, the protective rod can slide backwardly, and through the structural motion of the second electromagnetic mechanism, the locking of the cam by the lock catch can be released. In theprocess, control signals need to be sent to the two electromagnetic mechanisms respectively. When hot water is used for doing a laundry, after the laundry is done, the first electromagnetic mechanismreceives a control signal to make a motion, and at the time the door lock is not opened, so use safety of a user 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 on 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 catch to unlock the cam. [0003] When the existing automatic door lock is unlocked, an electromagnetic coil is used to complete the unlocking of the cam by one action. [0004] However, in actual use, sometimes when hot water is used for washing, because the temperature in the washing machine is relatively high, for safety considerations, 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, directly opening the door may cause danger to the user. Contents of the invention...
