Abstract

The invention provides a detection method and device for a stove surface temperature sensor, and relates to the technical field of kitchen appliances. The detection method comprises the following steps that 1, a temperature value detected by the stove surface temperature sensor is obtained; 2, when the variable quantity of the temperature value in a first preset time period is less than or equal to a first preset variable quantity, the temperature value is compared with a temperature threshold value; 3, when the temperature value is less than the temperature threshold value, the stove surface temperature sensor is judged to be invalid; 4, when the temperature value is greater than the temperature threshold value, the heating power of a stove is reduced, the temperature value is monitored within a second preset time period, and when the variable quantity of the temperature value within the second preset time period is smaller than or equal to a second preset variable quantity, it is judged that the stove surface temperature sensor fails. after 5, the temperature value exceeds the temperature threshold value, whether the stove surface temperature sensor fails or not can be judged by reducing the heating power and monitoring the variable quantity of the temperature value within the second preset time period, and failure detection on the stove surface temperature sensor under the condition of the full temperature period can be achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a detection method and device for a furnace surface temperature sensor. Background technique [0002] As a product of a new generation of kitchen revolutions, induction cookers have entered every household. Compared with traditional gas stoves, it has the advantages of high efficiency, energy saving, safety and environmental protection. [0003] During the heating process of the induction cooker, the surface temperature sensor needs to be used to transmit the temperature signal to the control circuit, so as to measure and control the temperature of the surface of the induction cooker, so as to prevent the induction cooker from overheating and ensure safety. [0004] In the prior art, when the induction cooker is turned on and heated normally, the furnace surface temperature sensor will be detected in real time when the temperature is below a certain temperature (gener...
