Abstract

The invention discloses a cooking induction heating device with accurate temperature induction, which ingeniously and simply overcomes the technical contradiction that the temperature measurement is inaccurate because a temperature-sensitive element and a temperature-sensitive probe, which comprise conductive elements and are arranged in a panel mounting through hole, heat per se in a stronger fluctuating electromagnetic field by mainly overcoming the traditional technical prejudice and arranging shield insulating magnetizers among the temperature-sensitive element, the temperature-sensitive probe and a heating coil. By arranging a waterproof ring and an easily detachable connecting structure, the cooking induction heating device is convenient to purify and clean; and by a matched cooking container with a groove, the cooking induction heating device senses the temperature more accurately and the cooking container is not easy to slide. The invention eliminates various technical contradictions in the actual use process, endows the scheme with quite strong practical valve and can be really applied to actual products, thereby realizing intelligentized cooking with high quality, energy saving and high automation.

Description

technical field [0001] The invention relates to an electric heating cooking tool, in particular to an electromagnetic induction heating device with accurate temperature sensing. Background technique [0002] The induction heating device is a cooking heating tool that uses electromagnetic induction heating. It directly heats the cooking container itself by changing the magnetic field. It has the advantages of high thermal efficiency, small thermal inertia, safe use, and convenient operation. Induction heating devices such as magnetic induction heating rice cookers, electromagnetic induction heating soybean milk machines, and electromagnetic induction heating kettles have also begun to be gradually promoted. [0003] Intelligent, high-quality cooking with an induction heating unit depends on the precise temperature sensing of the cooking vessel containing the food or water. Because the temperature probe of the induction heating device generally needs to be installed inside or...
