During cooking, the temperature control is particularly critical, in the prior art, a common snap-action temperature controller is generally adopted in an oven, and the snap-action temperature controller is a heat-sensitive reaction component which takes a bimetallic strip after temperature fixing _， When the temperature in the oven is increased, the generated heat is transferred to the bimetal wafer, and the bimetal wafer rapidly acts when the action temperature is set, and the contacts are opened or closed through the mechanism; when the temperature is reduced to the reset temperature setting, the bimetallic strip quickly returns to the original state, so that the contacts are closed or opened, the purpose of switching on or off a circuit is achieved, and the working circuit of the heating tube is controlled. However, since a certain time is required for heat conduction to the bimetal, the temperature in the oven cavity of the oven cannot be sensed in time, and the temperature in the actual baking of the food is difficult to be received correctly in the variable cooking mode of the oven, when the food is baked, the cooking effect is poor due to inaccuracy of temperature control of different types or weights of food.
