Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained according to the attached drawing of offer.
Fig. 1 is a kind of structural schematic diagram of electric cooker provided by the utility model.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to FIG. 1, Fig. 1 is a kind of structural schematic diagram of electric cooker provided by the utility model, which be can wrap
It includes：
Liner 2；Wherein the liner at the bottom is embedded with sheet metal 1；
Positioned at 3 lower section of cooker body, the heated base 4 comprising emitting magnetic strength group；Wherein heated base includes heated base shell；
Transmitting magnetic strength group 5 is fixed on the inside cavity of heated base shell, is used to form magnetic field so that sheet metal 1 forms inductive loop simultaneously
Fever.
The material composition of sheet metal 1 can be a kind of metal material, such as aluminium, tin, can also with alloy material, as steel,
Aluminium alloy, dilval etc., but it is not limited only to this.It should be noted that sheet metal as used herein be not limited in it is ferromagnetic
Preferably several metals of property, such as iron, cobalt, nickel, the utility model equally can produce whirlpool also directed in other under specific circumstances
Metal foil or alloy of stream, such as gold, silver, copper, aluminium or its alloy etc..Further, the material, shape of metal foil,
The selection of the parameters such as thickness also should be according to progress many experiments preferentially.Such as show that aluminium foil is less than 100khz in frequency through overtesting
Under the conditions of, it is most obvious to generate venturi effect in 0.05~0.1mm range internal efficiency highest for thickness.Through experimental demonstration, this is practical new
1 thickness of sheet metal provided by type can generate optimal vortex effect under conditions of less than 0.5 millimeter.
