Description

A kind of combined electromagnetic aluminum pot

Technical field

The present invention relates to a kind of cooking pot tool of electromagnetism heating, particularly a kind of combined electromagnetic aluminum pot.

Background technology

As everyone knows, the good aluminium of thermal conductivity, aluminium alloy, copper etc. do not possess the ability of the cutting alternation magnetic line of force, and can cut the ferritic stainless steel, cast iron, general steel plate etc. of the alternation magnetic line of force, and thermal conductivity is poor again.The electromagnetism cooking apparatus is to utilize the pan that can cut the alternation magnetic line of force, and the cutting high frequency alternation magnetic line of force produces eddy current, makes the pan heating realize food is heated.Electromagnetic technique have the flames of anger, safe in utilization, efficiency is high, power is big, adjustable power and the advantage that can combine with electronic technology well, but exists cooking pot tool must possess the attribute of " can cut the alternation magnetic line of force ", and the magnetic line of force is to directly act on pan to produce heat; Not only restricted the use that to cut alternation magnetic line of force material pan; In use because of cutting the thermal conductance rate variance of alternation magnetic line of force pan, the heat of generation is concentrated relatively, directly acts on food again simultaneously; So that when cooked rice or paste like food; Very easily concentrate the place to take place to stick with paste at the end, and that the not good position of conducting heat occurs is half-cooked, causes the serious bad phenomenon of cooking quality at heat.

In order to overcome the deficiency that electromagnetic heating technique exists; Domestic and international each big household electrical appliances esbablished corporation; And the knowledgeable people exploring always, and how that thermal conductivity is good the material that can not cut the alternation magnetic line of force can cut the method that the material of the alternation magnetic line of force organically combines with the thermal conductance rate variance.Disclosed like Chinese patent: the patent No. 96112765, the Japan of proprietary term " vessel for electromagnetic cooker and manufacturing approach thereof " is in Chinese patents; The patent No. 200610115411, the Korea S of proprietary term " oven for induction heating rice cooker " is in Chinese patents; The patent No. 02134462, proprietary term " a kind of internal container of electric cooker and manufacturing approach thereof "; The patent No. 200820066259, proprietary term " pot in a kind of pottery of electromagnetism heating electric rice cooker and the glass "; The patent No. 200620013330.5, domestic patent of proprietary term " container of charged magnetic induction heating sheet " or the like is attempted through new technical scheme, solves the deficiency that electromagnetic technique exists in culinary art.Summarize disclosed technology; The technical scheme that adopts has: adopt to have and can cut alternation magnetic line of force attribute and the high compound manufacturing pot of aluminium, copper product of thermal conductivity; The bonding material layers of cutting the alternation magnetic line of force in the aluminum or aluminum alloy pot the bottom of a pan; The material layers that the bottom of a pan soldering of aluminum or aluminum alloy pot can be cut the alternation magnetic line of force, the aluminum or aluminum alloy pot the bottom of a pan presses and can cut the material layers of the alternation magnetic line of force, and the pot body spraying plating that can not cut the alternation magnetic line of force can be cut the material film of the alternation magnetic line of force.

But above technical scheme is not enough below still existing: adopt to have and can cut the high aluminium of alternation magnetic line of force attribute and thermal conductivity, the pot of the compound manufacturing of copper product, and the manufacturing technique requirent height, material cost is high; The bonding material layers of cutting the alternation magnetic line of force in the aluminum or aluminum alloy pot the bottom of a pan, temperature resistant capability is poor, and service life is short, and production efficiency is low; The material layers that the bottom of a pan soldering of aluminum or aluminum alloy pot can be cut the alternation magnetic line of force, energy consumption is high, pollutes to weigh, and efficient is low, and cost is high; The aluminum or aluminum alloy pot the bottom of a pan presses and can cut the material layers of the alternation magnetic line of force, complex process, and product percent of pass is low, and cost is high; The pot body spraying plating that can not cut the alternation magnetic line of force can be cut the material film of the alternation magnetic line of force, and technology is immature, and thin being prone to of deposited metal comes off.And still there is poor thermal conduction in these technical schemes, the not good problem of culinary art performance.

Summary of the invention

The objective of the invention is to, on the basis of inheriting conventional punching press of aluminum or aluminum alloy pot or die casting manufacturing approach, in conjunction with heat transfer theory; Adopt the most frequently used technical scheme, utilize compound mode, with minimum material cost; The simplest production technology, the material that can not cut the alternation magnetic line of force that thermal conductivity is good, the combination of materials that can cut the alternation magnetic line of force with the thermal conductance rate variance becomes the electromagnetism cooking pot tool; When keeping the electromagnetic heating technique advantage, solve common electromagnetism cooking pot tool when cooked rice or paste like food, very easily take place to stick with paste at the end at the heat place of concentrating; And that the not good position of conducting heat occurs is half-cooked, causes the serious bad phenomenon of cooking quality.

For realizing above-mentioned purpose, technical scheme of the present invention is:

A kind of combined electromagnetic aluminum pot; Comprise aluminum pot body (1); Heater (2) and connector (3) is characterized in that: heater (2) is installed in the exterior bottom of aluminum pot body (1) through connector (3), is filled with heat carrier (4) between the joint face of heater (2) and aluminum pot body (1).

Between the joint face of said heater (2) and aluminum pot body (1), the heat carrier of filling (4) can be a paste, also can be Powdered, can also be sheet.

The face shape that said heater (2) is connected with aluminum pot body (1) is coincide, and the another side of heater (2) can be a convex surface, and concave surface can also be the plane.

Said heater (2) can be that the material of single the cut alternation magnetic line of force is processed, and also can by the material that can cut the alternation magnetic line of force and other material is compound processes.

The connected mode of said heater (2) and aluminum pot body (1) can be to be threaded, and also can be that buckle connects.

Beneficial effect of the present invention is: incite somebody to action independently heater (2) through connector (3); And the aluminum pot body of producing with conventional punching press or pressure casting method (1) makes up; Between the joint face of heater (2) and aluminum pot body (1), filling heat conduction, the heat carrier (4) that heat transfer property is good.Realize that with conventional punching press, extrusion process technology high efficiency produces low cost, high performance electromagnetism culinary art aluminum pot, when effectively solving common electromagnetism cooking pot tool cooked rice or paste like food, the serious bad problem of cooking quality.
