Abstract
The invention relates to a copper bottom frying pan, and belongs to kitchen ware. Existing iron for open fire and an existing stainless steel frying pot are quite low in heat efficiency, and a red copper frying pan is small, expansive and toxic. The copper bottom frying pan is composed of a pan side and a pan bottom, the pan bottom is made of red copper or copper alloy, the edge of the pan bottom and a lower opening of the pan side are welded together, and welding lines on the inner wall of the pan are flatly polished. The copper alloy can guarantee that the pan bottom is good in heat conduction and has certain hardness; and the aluminum oxide copper with the copper content higher than or equal to 98% is preferably selected. The inner wall and the outer wall of the pan bottom are plated, and the outer wall of the pan bottom had better be black due to the fact that the heat radiation absorptivity of the black pan bottom is high. When the copper bottom frying pan is used for open fire heating, energy saving can be obviously achieved, the performance cost ratio is high, and popularization is easy.
Description
Art
The present invention relates to a kind of kitchen tools, especially can frying pan at the bottom of significantly energy-conservation and easily universal copper.
Background technology
At present, known naked light frying pan has iron, stainless and copper.Iron frying pan is about 1/6th of red copper and the thermal efficiency is very low because of the thermal conductivity factor of iron, and the thermal efficiency is extremely low because stainless thermal conductivity factor is about 1/20th of red copper for Stainless pot for stir-frying.Though the red copper frying pan thermal efficiency is very high, easy in its Surface Creation one deck verdigris after long-time use, verdigris is poisonous to people.In addition low, the softening temperature of red copper hardness only has about 250 DEG C and be noble metal, therefore red copper frying pan is general all less and expensive and be difficult to popularize.
Summary of the invention
In order to overcome existing naked light iron, the Stainless pot for stir-frying thermal efficiency is very low and red copper frying pan is little and expensive and poisonous deficiency, the invention provides frying pan at the bottom of a kind of copper, frying pan at the bottom of this copper can not only be significantly energy-conservation, and cost performance is high.
The technical solution adopted for the present invention to solve the technical problems is: do a fork annular pot nation being greater than end opening suitable for reading with iron or stainless steel; Do a diameter lower convex circular the bottom of a pan suitable with pot nation lower port diameter with red copper or copper alloy again, the lower convex of the bottom of a pan well can discharge high temperature stress.The edge in the bottom of a pan and the end opening of pot nation weld together, and the weld of pot inwall is polished flat.Iron is generally wrought iron or steel, because wrought iron, steel easily weld with copper, copper alloy.Copper alloy preferably selects aluminium oxide copper, because the intensity of aluminium oxide copper, hardness, softening temperature and thermal conductivity are all higher, and it is little along with temperature raises hardness fall, and high-temperature creep resistance is good, and wearability is good, and processing characteristics is excellent.After mixing alundum (Al2O3) in red copper, hardness improves, but its thermal conductivity declines very fast, therefore in aluminium oxide copper, the content of copper is preferably not less than 98%.Because the chemical property of iron is sprinkled than work in copper, the bottom of a pan welded together with iron pan nation is not easily regeneration one deck verdigris by the electrochemical protection of iron pan nation; Therefore the bottom of a pan inside and outside wall electrodepositable of the pot of iron pan nation also can not be electroplated.And the bottom of a pan inside and outside wall of the pot of stainless-steel pan nation need be electroplated antirust, plating is generally titanizing or nickel plating.The outer wall in the bottom of a pan preferably turns black, because the thermal radiation absorption rate in the black the bottom of a pan is high.
The invention has the beneficial effects as follows, can be energy-conservation significantly, and cost performance is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the center section plan of first embodiment of the present invention.
Fig. 2 is the center section plan of second embodiment of the present invention.
In figure, 1. pot nation, the 2. the bottom of a pan.
Detailed description of the invention
In FIG, the lower convex circular the bottom of a pan 2 is made up of red copper or aluminium oxide copper, and in aluminium oxide copper, the content of copper is not less than 98%.The pot nation 1 of fork annular is made up of wrought iron, steel or stainless steel, the thickness at its edge, Xia Zhe the bottom of a pan 2, end opening edge.The diameter in the bottom of a pan 2 is slightly larger than the lower port diameter of pot nation 1.After the lower limb in the bottom of a pan 2 and the end opening top edge of pot nation 1 overlap, internal and external walls lap-joint all welds together, and pot inwall weld grinding is put down.The inwall Titanium Electroplating in the bottom of a pan 2 or nickel, outer wall turns black.
The circular the bottom of a pan 2 convex is in figure 2 the lower made up of red copper or aluminium oxide copper, and in aluminium oxide copper, the content of copper is not less than 98%.The pot nation 1 of fork annular is made up of iron or stainless steel.The diameter in the bottom of a pan 2 is equal with the lower port diameter of pot nation 1.After the edge in the bottom of a pan 2 docks with the end opening of pot nation 1, internal and external walls all welds together, and pot inwall weld grinding is put down.The inwall electronickelling in the bottom of a pan 2 or titanium, outer wall turns black.
