A kind of induction heating cooking device of pressure welding compound
Technical field
The utility model relates to metal cookware (as: pan), particularly a kind of induction heating cooking device of pressure welding compound.
Background technology
As everyone knows, the advantage of aluminum cook utensil (as: aluminum pot) be light, durable, heating is fast, heat conduction evenly, non-corrosive, therefore, become the preferred material of the medium and high classes cook utensil of most of brand.But its major defect directly to heat on electromagnetic oven.
In order to address this problem, Chinese utility model description (CN201167839Y) discloses a kind of cook utensil.It has the bottom being suitable for eddy-current heating, comprising: container, and this container is made up of the first material (as: aluminium) and is had from the outstanding multiple conical butt lugs of the outer surface of its diapire; And the heat distribution of disc format or diffuser plate, this plate is made up of the second ferromagnetic Heat Conduction Material (as: stainless iron) and is had the multiple through holes be formed at wherein.When installing in place, described disk has inner surface and outer surface, and described lug is inserted in described through hole and is also out of shape against described disk at least in part, and each described through hole of described disk has from the outstanding flange of described inner surface.The each described through hole of described disk also has the enlarged of contiguous described outer surface.This product passes through heat distribution or the diffuser plate of the disc format of container bottom, and cook utensil can be made directly to heat on electromagnetic oven.But its shortcoming is: owing to heat distribution or diffuser plate being provided with all through holes being used for being connected with container bottom lug, therefore, due to the existence of these through holes, the actual heating surface (area) (HS of cook utensil is made to receive very large impact.
In order to solve the problem further, the heat distribution having human hair to understand to be made by the ferromagnetic Heat Conduction Material (as: stainless iron) of full wafer by pressure welding complex method or diffuser plate are compound to bottom aluminum pot.Pressure welding is also referred to as Pressure Welding, it is typical Solid-phase welding mode, pressure must be utilized during Solid-phase welding to make the surface at position to be welded direct close contact in the solid state, and the temperature at position to be welded is raised, by regulating temperature, pressure and time, welding surface is made fully to carry out spreading and realizing combining between atom.Major advantage compared with CN201167839Y is: not used for the through hole or the groove that connect the bottom of a pan on the heat distribution of full wafer or diffuser plate, therefore, the actual heating surface area bottom aluminum pot increases greatly.But the said goods has still found following problem in actual use:
(1) aluminum pot heats when using on electromagnetic oven, and due to the eddy current effect of heat distribution or diffuser plate (as: stainless iron plate) electromagnetic field, cause the heating-up temperature in the bottom of a pan extremely uneven, the temperature being positioned at middle part, the bottom of a pan is high especially.When cooking fried food, often cause the food be positioned in the middle of the aluminum pot the bottom of a pan to decoct Jiao, and the food being positioned at periphery, the aluminum pot the bottom of a pan does not also have ripe, greatly have impact on the quality of food cooking.
(2) bottom aluminum pot because pressure welding is compounded with heat distribution or diffuser plate, make can not directly to press bottom aluminum pot and carve product annotation identification word, patterns such as (as:) product brand logo, trade names.
(3) heat distribution bottom aluminum pot or diffuser plate are at pressure welding compound tense, and its location is not too convenient, easily cause the front position bottom heat distribution or diffuser plate and aluminum pot to offset, affect the quality of product.

The induction heating cooking device of described pressure welding compound, is characterized in that: arrange cannelure further around this bottom portion of groove, and this cannelure is the further extension of depth of groove; This fold inward structure stretches into groove and falls into or snap in cannelure.
The induction heating cooking device of described pressure welding compound, is characterized in that: have groove in the middle of this cook utensil body bottom portion outer surface, recess edge extends to form the positioned edge higher than cook utensil body bottom portion downwards; There is in the middle of this heat-distribution plate the hole that shape and position correspond to positioned edge; When the outer surface compound tense of heat-distribution plate and cook utensil body bottom portion, this positioned edge stretches into hole; The height of this positioned edge and the consistency of thickness of heat-distribution plate.
The induction heating cooking device of described pressure welding compound, is characterized in that: this first material is aluminum or aluminum alloy, and this ferromagnetic Heat Conduction Material is stainless iron.
The induction heating cooking device of described pressure welding compound, is characterized in that: the cross section of this cannelure is rectangular recess, U-shaped groove or v-depression.
The induction heating cooking device of described pressure welding compound, is characterized in that: this groove and cannelure have the outer wall that one extends, and the outer wall of this cannelure has inside gradient.
The induction heating cooking device of described pressure welding compound, is characterized in that: this interior turnover structure and heat-distribution plate plane orthogonal.
The induction heating cooking device of described pressure welding compound, is characterized in that: this heat-distribution plate outer rim has the binding structure corresponding to cook utensil body bottom portion.
The induction heating cooking device of described pressure welding compound, is characterized in that: the channel section of this cook utensil body is for circular, and heat-distribution plate is and the suitable annulus with circular port of groove shapes and position.
Above technical characteristic, the utility model tool has the following advantages:
1, have the heat-distribution plate be made up of ferromagnetic Heat Conduction Material again bottom cook utensil of the present utility model, therefore cook utensil just can directly heat on electromagnetic oven.Heat-distribution plate of the present utility model does not have other through hole or groove except a hole of centre, and therefore the heating surface (area) (HS of this heat-distribution plate is larger.Have a hole in the middle of heat-distribution plate of the present utility model, this hole solves the eddy current effect due to electromagnetic field just, causes the problem that the heating-up temperature at the end of cook utensil is extremely uneven.When cooking food, the food directly contacted with container bottom can be cooked very even, can not produce the phenomenon of the raw ripe inequality of food.
2, cook utensil of the present utility model directly can see by the hole in the middle of heat-distribution plate the groove being positioned at cook utensil body bottom portion outer surface centre position, and product manufacturing person or sellers can direct pressure product annotations at quarter identification word, patterns such as (as:) product brand logo, trade names in the bottom surface of groove.
Have position and pressure welding location structure corresponding to shape in the middle of outer surface and the heat-distribution plate of 3, cook utensil body bottom portion of the present utility model, this structure is convenient to installation and the location of heat-distribution plate at pressure welding compound tense.
