Description

A precise temperature control induction cooker

technical field

The utility model is an electromagnetic cooker with precise temperature control, which belongs to the field of household kitchen equipment.

Background technique

The working principle of the existing induction cooker is to use the magnetic field lines in the magnetic field to pass through the bottom of the metal vessel (magnetic and conductive material), and an eddy current is generated in the metal vessel to make the metal vessel itself generate heat at a high speed, and then heat the food in the metal vessel. At present, when the temperature of electromagnetic heating appliances on the market is collected, the temperature at the bottom of the metal vessel (magnetic and conductive material) is transmitted to the temperature sensor in the induction cooker through a whole piece of insulating material panel (ceramic panel, microcrystalline panel, etc.) On the induction cooker, the main board integrated circuit on the induction cooker performs calculation processing, and then performs power adjustment, so as to meet the required temperature control requirements.

Since the bottom temperature of metal utensils (magnetic and conductive materials) is transmitted to the temperature sensor in the induction cooker through a whole piece of insulating material panel (ceramic panel, microcrystalline panel, etc.), because there are insulating material panels (ceramic panel, microcrystalline panel, etc.) ), so the temperature on the temperature sensor in the induction cooker cannot be equal to the real temperature at the bottom of the metal vessel (magnetic and conductive material). It belongs to a temperature radiation transfer method, and there is a certain temperature value between the two Error, the test of the temperature value is not accurate, resulting in the induction cooker not having the function of cooking. There are also attempts to perforate and install temperature measuring devices on insulating material panels, but limited to the materials used in existing panels, there is a problem of stress concentration, which leads to defects such as easy breakage during transportation, use, and processing, and high costs.
