Background
This section provides background information related to the present disclosure only and is not necessarily prior art.
In the prior art, a cooking appliance such as an oven or a microwave oven is usually configured to detect whether an oven door is closed by a travel switch provided on a door lock assembly. For example, when the oven door is in a closed state, the bolt on the door body can touch the travel switch on the box body, and at the moment, the control system of the cooking appliance judges that the oven door is closed, so that a heating program can be normally started to heat food in the cooking cavity; on the contrary, when the oven door is in an open state, the bolt on the door body cannot touch the travel switch, at the moment, the control system of the cooking appliance judges that the oven door is opened, and under the condition, the cooking appliance cannot start a heating program or stop heating food, so that the use safety of the cooking appliance is ensured.
However, the way of detecting the closed state of the oven door using the stroke switch has some problems in practical use. For example, the arrangement of the travel switch increases the volume of the door lock assembly, so that the door lock assembly occupies a larger installation space on the box body.
