Problems solved by technology

[0002] The widely used induction cooker basically installs the temperature sensing probe device on the lower surface of the panel. When in use, the pot is placed on the panel, and the bottom of the pot is directly in contact with the panel. When the electromagnetic wire generated by the coil under the panel passes through When the pot is made of ferromagnetic material, eddy current is generated at the bottom of the pot to generate heat, and the temperature detected by the temperature sensor device is the temperature after the heat generated at the bottom of the pot is conducted through the panel, so there are the following problems: 1. In terms of time late

Since the materials of the panel are mostly microcrystalline ceramics or glass, these materials are poor conductors of heat, and the heat generated at the bottom of the pot is detected by the temperature sensing probe device after being conducted by the poor conductor panel of heat, so that the detected temperature changes The temperature change relative to the bottom of the pan is delayed in time

2. The detected temperature has a large error compared with the temperature at the bottom of the pot

The heat generated at the bottom of the pot is detected by the temperature sensor device after it is conducted through the hot poor conductor panel. In the heating stage, the detected temperature is lower than the temperature at the bottom of the pot, plus the cooling fan in the furnace. , making the detected temperature lower, so the detected temperature has a larger error than the temperature at the bottom of the pot

3. The temperature inside the furnace is high

Due to the large error between the detected temperature and the temperature at the bottom of the pot and the delay in time, the constant temperature function of the constant temperature device cannot truly reflect the temperature at the bottom of the pot, which may cause the temperature at the bottom of the pot to be different from the temperature on the upper surface of the panel. Exceeding the set or allowable temperature range, thus burning the pan and panel

2. Reduced service life

Due to the high temperature in the furnace, the working environment of the electronic components in the furnace is deteriorated, so that the failure of electronic components increases and the service life decreases
