Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a door lock assembly for an appliance and a cooking device. Background Technology

[0002] Currently, the door lock structure of steam ovens on the market typically uses a door control switch to detect when the oven door is opened. When the user opens the door, the door control switch sends a signal to the control system indicating that the door is not closed, and the heating element for the steam oven function cannot be activated to ensure user safety. However, this design has a certain safety flaw. If the door control switch malfunctions during cooking and cannot recognize the door opening / closing operation, the heating element may still be working even after the user opens the door, potentially causing injury to the user.

[0003] Therefore, there is an urgent need for a door lock component for electrical appliances to solve the above problems. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a door lock assembly for an electrical appliance that can prevent the appliance from continuing to operate when the door is opened.

[0040] Please refer to Figures 1-7This utility model provides a door lock assembly for an electrical appliance, including a lock head structure and a function switch. The function switch includes a first function switch 41. The lock head structure includes a support 1, a lock hook structure 2, an elastic element 3, and a lock tongue 8. The support 1 includes a support body 11, which is mounted on the appliance's body 200. The first function switch 41 is mounted on the support 1 and electrically connected to the appliance's circuitry. The lock hook structure 2 includes a lock hook support 21 and a lock hook body 24 disposed on the lock hook support 21. The lock hook support 21 is rotatably connected to the support 1. The first end of the elastic element 3 is connected to the support 1, and the second end is connected to the lock hook support 21. The latch 8 has a hanging hole 81. The latch 8 is installed on the door 300 of the appliance. When the door 300 moves to the closed state, the latch body 24 hooks with the hanging hole 81. The latch 8 pushes the latch support 21 to rotate relative to the support 1 from the first position to the second position, so that the latch support 21 triggers the first function switch 41, the circuit of the appliance is energized, and the elastic element 3 is in the contracted state. When the door 300 moves to the open state, the latch 8 pulls the latch body 24 relative to the support 1 to reset from the second position to the first position, so that the latch support 21 disengages from the first function switch 41, the circuit of the appliance is disconnected, and the elastic element 3 is in the relaxed state.

[0041] The door lock assembly 100 of the electrical appliance provided by this utility model has a first function switch 41. When the door 300 is closed, the first function switch 41 is triggered, closing the switch and connecting the electrical circuit, allowing the appliance to operate its first function.
