Abstract

The invention discloses a temperature sensing device for preventing no-loading of a microwave oven. The temperature sensing device comprises two components, the first component is a ceramic chip, andthe second component is a temperature sensor. The temperature sensor and the ceramic chip are connected to each other, and the front surface of the ceramic chip is covered with a black glaze layer. The black glaze layer attached to the ceramic chip is formulated by adding 5%-40% of Fe-Cr-Co-based spinel black toner to a base glaze, and the base glaze comprises, by mass, 40%-65% of SiO2, 8%-15% ofAl2O3, 5%-10% of CaO, 0.5%-2% of K2O, 2%-5% of ZnO, 3%-7% of B2O3, and 5%-10% of ZrO2; and the black toner comprises, by mass, 40%-70% of Fe2O3, 10%-30% of Cr2O3, and 10%-30% of Co2O3. According to the temperature sensing device for preventing no-loading of the microwave oven, whether the microwave oven is in an on-loading state or not can be well determined through the temperature change of the ceramic chip with the black glaze layer, and then the microwave oven is adjusted and controlled through a computer board, so that the microwave oven is effectively prevented from no-loading.

Description

technical field [0001] The invention relates to a household appliance, in particular to a temperature sensing device for preventing a microwave oven from being empty. Background technique [0002] Microwave ovens are an indispensable household appliance for every family. With the development of the times, smart home appliances are becoming more and more popular. When the microwave oven is started with no load, a large amount of microwaves will gather in the cavity and cannot be consumed. They can only find leaks in the gaps, which may easily cause ignition at the gaps or cause harm to the human body after leakage; on the other hand, microwaves are easily emitted from microwaves. The nozzle leaks back and damages the magnetron launcher. For the design and manufacture of microwave ovens, how to intelligently control the no-load state of microwave ovens and realize intelligence has always been a difficult topic in the industry. At present, although many microwave oven manufac...
