Description
Technical field
The utility model relates to a kind of cooker, relates in particular to a kind of energy by the composite pan bottom of electromagnetic induction heat conduction.
Background technology
Traditional pot is as pressure cooker, frying pan, frying pan, the pans such as non-stick pan adopt aluminum material to make more, because aluminium is non-magnet material, therefore traditional aluminium matter pot is not suitable for using on electromagnetic stove, but making constant progress along with science and technology, the common people family that new heating cooler is as common in electromagnetic stove enters into widely, and aluminium matter pan cannot use the competitiveness that certainly will limit on its market on electromagnetic stove, there are scientific and technical personnel to develop the pan of composite pan bottom for this reason, its one is to be in compound last layer stainless steel bottom surface, original aluminium matter the bottom of a pan by it, bottom surface and the bottom of a pan are welded, its defect is processing technology complexity, need to be by Plate Welding the bottom at aluminium matter pot, welding needs special protruding standby, be easy to have influence on the fineness on surface, the bottom of a pan simultaneously, and the cost of welding is also higher.
Also have, if the patent No. is the Chinese utility model patent " composite pan bottom of aluminium matter pot " that is also ZL02217063.4 (notification number is CN2544654Y) just like a patent No. has disclosed so a kind of structure, it is at the compound upper steel plate in the bottom in the aluminium matter the bottom of a pan, it is characterized in that stamping out multiple hole flangings on the surface of steel plate, cold extrusion is carried out in the bottom that steel plate is fitted in to the aluminium matter the bottom of a pan, make to be squeezed in the hole flanging on steel plate after the aluminum metal distortion in the aluminium matter the bottom of a pan, the flange of hole flanging is pressed in the aluminum substrate in the aluminum pot the bottom of a pan simultaneously, tightly embrace with aluminum substrate, steel plate is composite and fixed on the bottom in the aluminium matter the bottom of a pan.It is simple that this composite pan bottom has processing, cost is low, connect the advantages such as more firm, but because it is that the bottom of a pan does not form the lug boss matching with hole flanging in advance, it be by cold-stamped mode directly by the steel plate amassing that has hole flanging to the aluminium matter the bottom of a pan, it is only because the side of hole flanging is inserted into the bottom of a pan, be combined in the bottom of a pan by the frictional force effect in hole flanging side and the bottom of a pan, therefore the combination in steel plate and the bottom of a pan is not also very firm, also have the composite pan bottom of above-mentioned aluminium matter pot thinner steel plate can only be expressed to the bottom of a pan of aluminium matter pot, otherwise, steel plate thickness is blocked up, make its flange be not easy to be inserted on the flat the bottom of a pan, therefore its application also has certain limitation.Process technology limit in addition, the flange height of hole flanging can not be too high, otherwise easily cause flange to destroy, and intensity declines, thereby causes composite joint firm not.
The patent No. is that 200720184320.2 Chinese utility model patents " composite pan bottom of aluminium matter pot " disclose a kind of composite pan bottom for this reason, its aluminium matter pot bottom part compound fixing on magnetic conducting and heating panel, it is characterized in that forming in advance multiple recessed portions at described pot bottom part, the upper surface of magnetic conducting and heating panel is made recessed the multiple and described lug boss that portion matches in advance, magnetic conducting and heating panel is fitted on the bottom in the aluminium matter the bottom of a pan, recessed portion of pot bottom part is fastened on the lug boss of magnetic conducting and heating panel, by extrusion modling, make lug boss be squeezed into tensioner in recessed portion, magnetic conducting and heating panel is composite and fixed on the bottom of aluminium matter pot.This composite pan bottom is smooth attractive in appearance, but the extrusion modling in magnetic conducting and heating panel and the bottom of a pan is hot extrusion, and being needs heating, can not adopt cold extrusion shapedly, therefore manufactures cumbersomely, and cost is also relatively high.
