Abstract

The invention discloses a temperature measurement device and method for an electric heating appliance. A semiconductor temperature difference power generation chip is adopted, the internal and external temperature difference in the electric heating appliance working process can be utilized for providing power for a measuring circuit and sending measured data wirelessly, wired connection between the measuring circuit and a control circuit is avoided, placement of the measuring circuit is greatly facilitated, and a temperature measurement top cover can be designed to be an active type or a separated type conveniently. Meanwhile, due to the fact that the semiconductor temperature difference power generation chip does not need to be replaced, the whole circuit can achieve very good waterproofand seal functions, and the reliability and durability of work re improved.

Description

technical field [0001] The invention belongs to the technical field of measuring electric heating appliances, and in particular relates to a temperature measuring device and method for electric heating appliances. Background technique [0002] Electric heating appliances (such as electric rice cookers, etc.) must detect the temperature inside the appliance when working. The general method for temperature detection of such products is to add a temperature sensor outside the bottom of the pot for measurement. The material in the tank (such as water, rice, etc.) is separated by a pot tank, so the actual measured temperature is different from the temperature in the tank, especially when the material in the tank is rice, the rice will settle at the bottom of the tank, At this time, the external temperature sensor at the bottom of the pot needs to indirectly measure the water temperature in the pot through the pot liner and the sediment layer of rice, which will cause a large erro...
