Abstract
The utility model relates to an electric heating cooker, which belongs to the technical field of the electric heating cooker, the utility model is composed of a pot body, an electric heating element, an electric controller and a socket, and the bottom surface of the pot body and the electrical heating film of a stainless base plate are connected to be a compound entirety through the manners, such as: crimping, welding, binding or sheet metal processing, etc. An electric contact on the edge of the electrical heating film at the bottom surface of the compound pot body is contacted with an electrode on the socket, the electrode is communicated with the electric controller, and the utility model can be used after switched on. The utility model has unique design, elaborate model, and smaller cost, the composite surface formed by the bottom surface of the pot body and the electrical heating film is wearable, the electric heating conversion efficiency comes to 92-94%, and the aspects on the quality safeguard and the safety performance have very large superiority.
Description
Technical field
The utility model relates to the electric-heating cooking utensil technical field, specifically, relates to a kind of electric-heating cooking utensil that electrical heating elements is compound in pot body.
Background technology
The electric-heating cooking utensil that existing market is sold, its traditional mode of heating generally is divided into two kinds: electric hot tray heating and electrothermal tube heating.Electric hot tray thermal energy conversion efficiency low (being about 50%), big and heave, disk body is yielding, and thermal inertia is big; Though electrothermal tube relatively hot efficient higher (being about 75%), its syndeton complexity, element is fragile, and is in use also inconvenient.These two kinds of Electric heating because pot body and electrical heating elements are separated, have caused the low main cause of thermal conversion efficiency.
Summary of the invention
The purpose of this utility model is for a kind of higher thermal energy conversion efficiency that has is provided, the electric-heating cooking utensil that is connected as a single entity with electrical heating elements and pot body.
In order to achieve the above object, electric-heating cooking utensil of the present utility model comprises a pot body, electrical heating elements, electric controller and base, described pot body is aluminum pot or aluminum alloy pan, described electrical heating elements is to be the electric heating film element of substrate with the stainless steel, and this element and the body underrun crimping of described pot or welding become one both.Electrothermic film element also can make it be connected to become a composite monolithic by modes such as bonding or sheet metal processing.The electric heating film edge electric contact that is positioned at of described composite monolithic contacts with electrode on the base, and electrode communicates with described electric controller, connect power supply after, electric-heating cooking utensil just can follow procedure instructs finishes this cooking process.
The bottom of a pan and the compound one electric-heating cooking utensil of electric heating film element of the utility model design have brought very big benefit and facility for all many-sides such as shape design, manufacturing cost and use of product; The structure of the utility model composite monolithic makes it also demonstrate very big superiority aspect quality guarantees such as waterproof and slip-off preventing and the security performance; The bottom surface that is compounded to form by pot body bottom surface and electric heating film has stronger rub resistance, and can make original thermal efficiency bring up to 92-94%, and the energy and economic benefit are very remarkable, have very vast market prospect.
The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is pot of the present utility model body and the electric heating film element schematic diagram after compound
Fig. 2 is an embodiment of electric heating cooker of the present utility model
Among the figure: pot body 1, pot cover 2, electric heating film 3, pot body bottom surface 4, electric contact 5, base 6, electric controller 7, power supply 8, above-mentioned each parts are interrelated, constituted the electric heating cooker schematic diagram jointly.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described
Select a stainless steel substrate electric heating film 3 similar to 4 shapes size at the bottom of the aluminum alloy pan, handle through preprocessing, evenly form projection with holes at the electric heating film element surface, reason back, strength electric heating film is fitted in a pot body bottom surface 4, then bottom of pot body is heated, when being heated to pot body metal softening, compress compound then, make electric heating film and the crimping of pot body become a composite monolithic, as shown in Figure 1.
Embodiment 2
Surface at electric heating film 3 evenly sprinkles a certain amount of solder flux in advance, this solder flux is 140-150 ℃ a low-melting-point metal, then the electric heating film element is closely contacted with pot body bottom surface 4, by high-frequency heating, exert pressure, make an electric heating film element and pot body bottom surface melting welding a becoming composite monolithic (with reference to shown in Figure 1).
Claims (3)
1. an electric-heating cooking utensil comprises aluminum alloy pan body, electrical heating elements, electric controller and base, it is characterized in that electrical heating elements is compound in a pot body bottom surface by crimping or welding, becomes one both.
2. electric-heating cooking utensil according to claim 1 is characterized in that electrical heating elements is is the electric heating film element of substrate with the stainless steel, and electric heating film element electric contact contacts with electrode on the base.
3. electric-heating cooking utensil according to claim 1 and 2 is characterized in that the electric heating film element also can be compound with pot body bottom surface by bonding or sheet metal processing method.
