Since the light sources are different according to the structural design and the use state of the cooking appliance, theoretically, there are various sources of light that can be transmitted through the light-transmitting hole 111.

For example, in the present invention, the pot cover 3 is provided with a light emitting unit, the light emitting unit can emit light into the heat insulation cover 11, and the light can be emitted through the light hole 111. The light-emitting unit is used as a light source, the emitted light can relate to a cooking chamber formed inside the heat-insulating cover 11, and the light can be emitted from the light-transmitting hole 111 when the inner container 2 is not placed in the heat-insulating cover 11, so that the photosensitive sensor 12 receives the light and generates an electric signal for changing the working state of the cooking utensil, and the use safety of the cooker is ensured.

It should be noted that the present invention is not limited to the above-mentioned type of the light emitting unit of the pot cover 3, and any one of the following embodiments can be adopted:
