Problems solved by technology

[0002] The door lock of electrical appliances plays a vital role in electrical appliances. When the electrical appliances are working normally, in order to ensure safety, the working space inside the electrical appliances needs to be a closed space, especially for washing machines, dishwashers and other electrical appliances. Open it at will, not only the outside sundries may enter the appliance and cause damage to the appliance, but also people who accidentally touch the internal working parts of the appliance may cause danger and cause unnecessary damage, and if the door lock of the appliance cannot work normally When the lock is guaranteed, it will also cause the items inside the appliance to fly out of the working space, which will seriously affect the product quality of the appliance and bring great inconvenience to normal use.
[0003] In response to the above problems, people have designed various electrical door locks to improve the safety factor of electrical appliances, so that the door can be automatically locked when the electrical appliance is working, and cannot be opened from the inside, and after the door is opened from the outside, the electrical appliance can stop working in time
The existing electrical door lock switches are basically controlled by electro-electric drive devices. When the electrical door lock switch is in the locked state, if the power is cut off, the electrical door cannot be opened manually.
