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.
