Detailed Description
The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.
The embodiment of the utility model provides a lock auto-lock alarm device for electric appliance, as shown in fig. 1-5, lock auto-lock alarm device for electric appliance, including casing, upper cover 1 includes rotating cover 5 and fixed lid 6, the lower extreme of rotating cover 5 is equipped with electromagnetic block 2, be equipped with the detection device that is used for detecting electromagnetic block 2 magnetic field intensity on fixed lid 6, the detection device electricity is connected with the controller; when the detection device detects that the magnetic field intensity of the electromagnetic block 2 is a preset value, the controller controls the washing machine to stop working and give an alarm.
