Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor used for a household appliance oven. Background Art

[0002] An oven is a kitchen appliance that uses radiant heat from electric heating elements to bake food. It needs to provide a stable temperature environment to ensure the baking effect of the food. The temperature sensor can detect the temperature inside the oven and transmit the temperature signal to the oven control system. The control system controls the operation of the heating element based on the feedback from the sensor, thereby achieving precise control of the oven temperature. However, existing temperature sensors themselves have a certain degree of thermal inertia, that is, the sensor responds slowly to temperature changes. When the temperature of the oven changes rapidly, the temperature sensor may not be able to reflect the temperature change in a timely and accurate manner, resulting in the oven control system being unable to adjust the operation of the heating element in time, thereby affecting the temperature control accuracy of the oven.
