A rice cooker vacuum pot inner thermostatic device

Abstract

A rice cooker vacuum pot temperature control device, which is composed of a metal inner pot, an outer pot and a shell, the top of the shell is embedded with a support ring, and the support ring is sealed and connected with the inner and outer pots; the inner pot is connected with the outer pot A vacuum layer is formed between the tanks controlled by a vacuum pump, and ring-shaped multi-stage heating coils are evenly distributed on the bottom of the outer tank. The present invention overcomes the deficiencies of the prior art. By adopting the electromagnetic induction heating technology, ring-shaped multi-stage heating coils are evenly distributed on the bottom of the outer container, and the alternating current is connected through the multi-stage electromagnetic coils to directly heat the metal inner container. Heating, over the heat conduction process of the heating plate, the temperature rises rapidly, and realizes the surrounding and uniform heating of the entire inner tank. Heating, combined with vacuum heat preservation technology on this premise, can effectively wrap the heat energy and reduce heat energy loss, so that the cooking process is more efficient and the heating is more uniform.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, in particular to a constant temperature device for a rice cooker vacuum pot. Background technique [0002] The electromagnetic induction heating cooker (IH cooker) is energized in the ring-shaped heating coil to generate magnetic force lines, and the electromagnetic coil generates alternating current to make the pot oscillate and generate heat, thereby heating the food. Therefore, in order to cook using such an IH cooker, it is usually necessary to use a conductive metal inner pot. However, from the perspective of heat preservation, the traditional electromagnetic induction heating cooker does not have the performance of heat preservation and heat insulation, which will prolong the heating time, thereby causing waste of energy. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a rice cooker vacuum...
