Description

technical field [0001] The invention relates to cookware, in particular to a wireless temperature-measuring cooker, an electromagnetic cooker and a wireless temperature-measuring method. Background technique [0002] In real life, the use of electromagnetic heating for cooking and boiling water has penetrated into people's lives, such as electric rice cookers and induction cookers. The induction cooker mainly adopts the principle of electromagnetic induction, and uses the magnetic field lines generated by the electromagnetic coil to convert into heat energy, so that the pan on the panel can heat itself at high speed, with high electromagnetic heating efficiency, energy saving and environmental protection; Conductor, the temperature detection circuit located on the bottom surface of the pot panel senses the temperature of the pot body through the pot panel, which has the disadvantages of slow temperature sensing, large temperature measurement error and low detection reliabili...

AI Technical Summary

Problems solved by technology

The induction cooker mainly adopts the principle of electromagnetic induction, and uses the magnetic field lines generated by the electromagnetic coil to convert into heat energy, so that the pan on the panel can heat itself at high speed, with high electromagnetic heating efficiency, energy saving and environmental protection; Conductor, the temperature detection circuit located on the bottom surface of the pot panel senses the temperature of the pot body through the pot panel, which has the disadvantages of slow temperature sensing, large temperature measurement error and low detection reliability, especially when the pot is dry. When cooking, it takes a certain amount of time to conduct the high temperature to the temperature detection circuit, which not only causes the pot to be easily burned out and deformed, wastes electricity, but also damages the induction cooker.

At present, there is another method of using infrared temperature measurement. An infrared temperature measurement circuit is installed under the microcrystalline panel. Infrared temperature measurement is easily disturbed by external environmental factors. The temperature of the pot, in addition, the transmission temperature of ordinary glass is 0-500°C, and the infrared wavelength transmittance is extremely low, so it can only measure the temperature radiated from the pot to the microcrystalline panel. The actual temperature of the pot has a large error. The perforation on the panel and the installation of infrared lens glass will greatly improve the glass perforation process and the waterproof requirements of the perforation; if the entire panel uses infrared transparent glass, the product cost will be greatly increased, and the fragility of infrared transparent glass cannot be satisfied.
