Wireless temperature measurement method and pot

Abstract

The invention provides a wireless temperature measurement method and a cooker. According to whether there is a potential difference between any two points on the cooker, the timing of starting the temperature measuring device and the transmitting device and sending the temperature data of the cooker to the induction cooker is controlled. Since the induction cooker only needs to During work, there will be a potential difference between any two points on the pot, thereby improving the timeliness and accuracy of sending temperature data from the pot to the induction cooker.

Description

technical field [0001] The invention relates to the technical field of electromagnetic cookers, in particular to a wireless temperature measuring method and a cooker. Background technique [0002] Induction cooker, also known as induction cooker, is the product of the modern kitchen revolution. It does not need open flame or conduction heating to generate heat directly at the bottom of the pot, so the thermal efficiency has been greatly improved. An induction cooker is an electric cooking appliance made using the principle of electromagnetic induction heating. It is composed of high-frequency induction heating coil (ie excitation coil), controller and ferromagnetic material pot bottom cooker and other parts. When in use, an alternating current is passed into the heating coil, and an alternating magnetic field is generated around the coil. Most of the magnetic field lines of the alternating magnetic field pass through the metal pot body, generating a large amount of eddy cur...

Problems solved by technology

[0004] However, the above method of measuring temperature data is greatly affected by the external temperature. When the external temperature is high, the wireless transmitter may send temperature data even when the induction cooker is not heated. When the external temperature is low, the induction cooker may have been heated. For a long time, the wireless transmitting device has not sent temperature data, so there is a problem that the induction cooker cannot obtain the temperature data of the pot in real time, and because in the low temperature environment, the pot will lag behind in heating and heating, at this time, use the above method to send the temperature data, it is also prone to the problem that the induction cooker is already heating, but the temperature information of the pot cannot be obtained in time
