Electromagnetic rice cooker

Abstract

The invention discloses an electromagnetic rice cooker, in particular to an electromagnetic rice cooker which is provided with a non-contact electromagnetic induction temperature measuring device, belonging to the field of electromagnetic kitchen ware. The electromagnetic rice cooker comprises an inner pot, an electromagnetic heating coil, a control circuit, a magnetic temperature sensing element and a temperature measuring circuit, wherein the control circuit heats the inner pot by controlling the switching-on and the switching-off of the electromagnetic heating coil, and the temperature measuring circuit and the magnetic temperature sensing element are not in contact with the inner pot. The electromagnetic rice cooker can indirectly achieve the detection of the temperature, and has the advantages of accurate measurement, simplicity, practicality and easy realization; the bottom of the electromagnetic rice cooker has no need of perforating, thereby improving the cleaning performance and the safety performance of the whole electromagnetic rice cooker; and a plurality of temperature points can be detected, thereby meeting various cooking requirements of the electromagnetic rice cooker.

Description

technical field [0001] The invention relates to an electromagnetic electric cooker, in particular to an electromagnetic electric cooker provided with a non-contact electromagnetic induction temperature measuring device. Background technique [0002] An electromagnetic rice cooker is a household appliance that uses an electromagnetic field to use an inner pot made of a ferromagnetic material as a load to directly heat rice and water in the pot. In the prior art, a contact temperature detection method is usually used in the temperature control process of the electromagnetic rice cooker. The contact temperature detection method is to use the temperature at the bottom of the pot to control the temperature by contacting and conducting to the heat-sensitive element. Press the start button, the electromagnetic rice cooker starts to work, the microcomputer detects the temperature of the main thermostat and the temperature of the upper cover sensor, when the corresponding temperatur...

Problems solved by technology

[0009] 2. The spring is in a high temperature and compressed state for a long time, and it is easy to fail, causing the temperature sensor to not be in full contact with the bottom of the inner pot. The specific temperature point allows the heat-sensitive element to get the signal accurately and timely, and it is difficult to realize the accurate and automatic control of the temperature of the rice and water in the pot during the cooking process;

[0010] 3. Due to the hole in the middle, water and other objects can easily fall into the heating plate, which will affect the cleaning performance and safety performance of the whole machine
