Abstract

The invention discloses a heating temperature measurement circuit and a temperature detection method thereof, a cooking device and a storage medium, the heating temperature measurement circuit is arranged on one side of a panel, is used for heating and measuring the temperature of a metal object placed on the other side of the panel, and comprises a first coil and a second coil; the temperature detection method comprises the steps of providing an excitation signal for a first coil so that a metal object can generate eddy current, and further enabling a second coil to generate a receiving signal by the eddy current; determining the measurement temperature of the metal object according to the excitation signal and the receiving signal; obtaining a current disc spacing, wherein the disc spacing is the distance between the first coil and the other side of the panel; and determining the actual temperature of the metal object according to the current disc spacing and the measured temperature. In this way, the accuracy of temperature detection is improved.

Description

technical field [0001] The present application relates to the technical field of temperature detection, and in particular, to a heating temperature measurement circuit and its temperature detection method, a cooking device, and a storage medium. Background technique [0002] Generally, when heating a metal object, it is necessary to detect and control the temperature of the metal object. Taking a cooking device as an example, in order to achieve good control of the cooking device and make the cooking device heat the pot, it is necessary to measure the temperature of the pot. temperature. For example, to use a set heating curve to heat a pot, it is necessary to detect whether the temperature of the pot meets the set heating curve. For another example, when the temperature of the pot is abnormal, the cooking device can be stopped from heating. [0003] One of the existing methods is to detect the temperature of the cookware through a thermistor, but due to the position settin...
