The temperature sensor is electrically connected to the power supply; the temperature sensor comprises an acting part for connecting or disconnecting the power supply and temperature sensing parts which are electrically connected to the acting part; the temperature sensing parts are in heat conduction with the heating element by virtue of connecting arms, and by virtue of the temperature sensing parts, temperature in the electric frying pan is sensed; and the connecting arms are made from two materials different in heat conductivity coefficient. According to the temperature sensing device provided by the invention, the heat conductivity coefficient of the connecting arm can be controlled between two heat conductivity coefficients, so that the heat conductivity coefficient is prevented from changing too fast or too slowly.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a temperature sensing device and an electric fryer with the temperature sensing device. Background technique [0002] The heating element of the electric fryer currently used mainly has two forms: one is that the heating element is arranged outside the inner pot, and the other is that the heating element is arranged in the pot. [0003] When the heating element is arranged in the pot, the electric fryer is also provided with a temperature sensing device for sensing the temperature in the electric fryer pot and controlling the on / off of the power supply. The temperature sensing device usually includes a temperature sensing part for sensing the temperature in the pot and an action part for controlling the on / off of the power supply. The temperature sensing part is in thermal conduction with the heating element through the connecting arm. In the existing temperature sensi...

AI Technical Summary

Problems solved by technology

In the existing temperature sensing device, the connecting arm is usually made of a single material of aluminum or iron, and the heat conduction is too fast or too slow

The thermal conductivity is too fast or too slow will have adverse effects

For example, when the heat conduction of the connecting arm is too fast, the thermostat will trip prematurely, and the oil temperature is very low

If the heat conduction of the connecting arm is too slow, the temperature limiter will trip too slowly, which may cause a fire

[0004] At present, in this field, different heat conduction rates are usually obtained by adjusting the size of the connecting arm, but the range of this adjustment is not large, and it is difficult to meet the safety requirements of various countries, causing great safety hazards
