Problems solved by technology

[0004] But in above-mentioned existing electric cooker, no matter how the kind of pot is, all can produce quite high temperature in cooking process, like this, the heat that radiates outside pot is also many, and cooking efficiency is not high
[0005] In particular, when the heat capacity of the pot used is relatively large, due to its characteristics, the temperature rises slowly at the initial stage of cooking, and the above-mentioned heat dissipation will cause the problem that the temperature rises even slower.

Embodiment 1

[0023] Such as Figure 1~3 As shown, the electric rice cooker housing 1 of the present invention is composed of an outer housing 3 and an inner housing 4 in which the upper partition is closed by an annular frame body 2, and the pot 5 is arranged inside the inner housing 4 in a manner that can be freely entered and withdrawn. in space.

[0024] Specifically, the opening flange 6 of the pot rests (clamps) on the vertical edge 7 of the frame 2 .

[0025] The inner casing 4 is integrally formed of a cylindrical upper protective frame 8 and a bottomed cylindrical lower protective frame 9 .

[0026] The top of the electric rice cooker housing 1 is opened / closed by a cover 12 , and the cover 12 rotates around the rotating shaft 11 covered by the rotating shaft cover 10 . The buckle 13 plays a role in keeping the cover 12 in a closed state. When the buckle 13 is disengaged, the cover 12 will be opened under the action of the spring 14 . In addition, in order to prevent the opening...

Embodiment 2

[0058] Figure 4 It is a schematic diagram of Embodiment 2 of the present invention. Wherein, the pot 5a is formed by a non-magnetic material with a larger heat capacity than the magnetic body metal, such as pottery material or porcelain material, etc., and the outer side of the pot 5a is covered with a heating element 32 formed by a magnetic material, and at least part of the heating element 32 is provided with Exotherm suppression layer 27.

[0059] Other components of the rice cooker are the same as figure 1 , 2 Similarly, the description of its specific configuration follows the description of Embodiment 1.

[0060] After adopting the above structure, the magnetic field lines generated when the electromagnetic induction coils 23, 24, 25 are energized will pass through the heat release suppression layer 27 to reach the heating element 32, and the heating element 32 will be heated by electromagnetic induction.

[0061] The heat generated by the heating element 32 is tran...

Abstract

The aim of the present invention is to provide an electric cooker, capable of effectively using the heat of the cooker to cook, further improving the cooking efficiency. In the electric cooker of the invention, a electric cooker casing (1) may be closed by a lid (12), an inner boiler (5) may be fetched and loaded freely from / on the casing (1), the boiler (5) is heated by electromagnetic induction coils (23, 24, 25) through electromagnetic induction. In addition, an external surface of at least part of the boiler (5) is provided with a heat liberation restraining layer (27) which is made of material that is permeated by magnetic force line such as silica-gel resin. in this way, the heat emitting outside may be restrained, and the cooking efficiency may be improved.

Description

technical field [0001] The invention relates to an electric rice cooker for cooking rice through electromagnetic induction heating. Background technique [0002] In the existing electric rice cooker, the pot used for cooking is made of magnetic material, the bottom of the pot and the lower part of the outer peripheral surface are provided with electromagnetic induction coils, and the magnetic lines of force generated by the electromagnetic induction coils cause the pot to heat up, thereby the contents in the pot are heated. heating. [0003] In addition, pots made of pottery materials or porcelain materials (that is, materials for making pottery and porcelain) have also appeared recently, and the pots are heated by electromagnetic induction heating the magnetic bodies arranged on the outside thereof. Since the heat capacity of pottery and porcelain is relatively large (heat capacity refers to the technical term for the heat required to increase the temperature by 1 degree, ...
