Rice cooker vacuum pan container constant temperature device

Abstract

A rice cooker vacuum pan container constant temperature device is composed of a metal inner container, an outer container and a shell, a supporting ring is embedded into the top of the shell and connected with the inner container and the outer container in a sealed mode, the portion between the inner container and the outer container is controlled through a vacuum pump to form a vacuum layer, and annular multi-level heating coils are evenly distributed at the bottom of the outer container. Defects in the prior art are overcome, and by the adoption of the electromagnetic induction heating technology, the annular multi-level heating coils are evenly distributed at the bottom of the outer container; as the multi-level electromagnetic coils are connected with alternating currents, the metal inner container is directly heated, the heat transfer process of a heating disc is omitted, temperature rises fast, the whole inner container is evenly heated in a surrounded mode, the multi-level electromagnetic coils are connected with the alternating currents to generate oscillations and can heat the inner container without making direct contact with the inner container, on the premise, a vacuumizing heat preservation technology is matched, heat energy is effectively wrapped, heat energy loss is reduced, the cooking process is more efficient, and 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...
