Problems solved by technology

However, in actual use, for the temperature sensor of this structure, since the thermistor and the jump-type thermostat with the hook are close to the heat-conducting cover made of aluminum cover, most of the heat absorbed by the heat-conducting cover is transferred to the heat-conducting cover with the hook. The sudden jump thermostat absorbs, which will reduce the sensitivity of the thermistor to measure the temperature of the bottom of the rice cooker, affecting the use effect

Abstract

The invention provides a temperature sensor capable of improving thermistor sensitivity. The temperature sensor comprises a snap-action thermostat with hooks, a thermistor, an inner support, a heat conducting cover, an inner cup, an outer cup and a spring. The heat conducting cover is pivoted to an upper opening of the inner cup, a lower opening of the inner cup is downwardly provided with a vertical supporting leg which is vertically and movably clamped at a limiting gap in the bottom of the outer cup, and the spring is arranged between the pivot position of the heat conducting cover and the bottom of the outer cup. The temperature sensor further comprises a heat insulating spacer which is arranged between the inner top surface of the heat conducting cover and the top surface of the snap-action thermostat with the hooks, the snap-action thermostat with the hooks is fixed through the inner support, and the thermistor is closely attached to the inner top surface of the heat conducting cover. By additional arrangement of the heat insulating spacer between the heat conducting cover and the snap-action thermostat with the hooks, influences on the thermistor in measurement of internal bottom temperature of an electric cooker are reduced, and thermistor sensitivity is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances spare parts, in particular to a temperature sensor capable of improving the sensitivity of a thermistor. Background technique [0002] The application number is 2017205022966, and the patent application titled a new type of temperature sensor proposes a temperature sensor that combines an innovative anti-dry switch with a pull hook with the existing inner and outer cup structure of the magnetic steel temperature limiter to solve The problem of high accuracy of the installation dimensions required by the fixed plate installation of the temperature limiter switch with the hook is solved. However, in actual use, for the temperature sensor of this structure, since the thermistor and the jump-type thermostat with the hook are close to the heat-conducting cover made of aluminum cover, most of the heat absorbed by the heat-conducting cover is transferred to the heat-conducting cover with the...
