Detailed Description

The utility model is further illustrated by the figures and examples.

As shown in fig. 1: the utility model provides an aluminium system pot bottom structure that possesses IH heating, includes aluminium system pot body 1, circular vacancy 2 has been seted up to aluminium system pot body 1's bottom to form the holding area of certain indent in aluminium system pot body 1 bottom, place heat conductor 3 in this holding area, and adopt laser welding or brazing process to combine an aluminium system film 4 in aluminium system pot body 1's bottom, inlay heat conductor 3 between aluminium system pot body 1 bottom and aluminium system film 4.

Wherein the heat conductor 3 can be made of heat conducting materials such as graphite, copper sheets and the like, so that more uniform heat conduction is provided for the bottom of the pot.

Considering that the bottom of the aluminum pot body 1 needs to be provided with a cover plate 5 (such as a stainless steel plate or iron) to increase the magnetic permeability. However, because the aluminum and the cladding plate 5 cannot be integrally formed, even if the aluminum and the cladding plate are adhered, the aluminum and the cladding plate are different in expansion coefficient, and also different in expansion coefficient and contraction coefficient, and the aluminum and cladding plate can be easily separated after long-term use, so that the aluminum bottom plate 4 made of the same material is used for limiting the heat conductor 3, and the aluminum bottom plate 4 made of the same material is not easy to separate after long-term use.

Secondly, the arrangement of the aluminum bottom plate 4 can be more flexible and diversified in the mode of fixing the stainless steel plate at the bottom of the aluminum pot body 1, and the influence on the bottom of the aluminum pot body 1 is reduced (as in the prior art, the flat bottom surface of the outer bottom of the aluminum pot body 1 is required to be provided with bulges in a circular array, and the external magnetic material layer is correspondingly provided with holes for connection, or the holes are embedded in the pits formed in the pot bottom in a rivet mode). Specifically, the method for bonding the aluminum backsheet 4 and the cover plate 5 used in this embodiment is as follows.

As shown in fig. 2-3: the aluminum bottom piece 4 arranged outside the pan bottom is provided with a groove to replace the way of directly arranging the bottom of the aluminum pan body 1, so that the operation is more convenient. The slot position comprises a buckling slot 6 circumferentially arranged on the outer edge of the aluminum bottom sheet 4 and a limiting notch 7 arranged on the bottom surface of the opposite inner side of the buckling slot, and a limiting block 8 adapted to the buckling slot 6 and a buckling block 11 adapted to the limiting notch 7 are correspondingly arranged on the covering plate 5, and can be bonded into a whole by adopting die casting.

It should be noted that, the lamination of the cover plate 5 and the aluminum bottom sheet 4 may be performed before the aluminum bottom sheet 4 is welded to the bottom of the aluminum pot body 1, so as to avoid the influence of the lamination on the aluminum pot body 1.

Secondly, the matching of the circumferential groove position with the buckling block 11 and the limiting block 8 ensures that the contact between the aluminum bottom sheet 4 and the shroud plate 5 is larger, and the aluminum bottom sheet 4 and the shroud plate 5 are firmly embedded and clamped, so that the aluminum bottom sheet is not loosened due to the influence of different expansion coefficients, and the falling problem is not easy to occur. Of course, even if the cover plate 5 and the aluminum bottom plate 4 fall off, the cover plate and the aluminum bottom plate can be pressed together again at the later stage because the cover plate and the aluminum bottom plate are both arranged outside the pot body.

Further, as shown in fig. 4: considering that the cladding plate 5 is also required to be die-cast and compounded with the aluminum bottom plate 4, the embodiment can also adopt the steps of directly spraying an iron layer on the bottom of the aluminum bottom plate 4 (the aluminum bottom plate 4 is sprayed before being welded to the bottom of the pot body), and baking and fixing at high temperature to form the IH heating function on the bottom of the aluminum pot body 1. Of course, the aluminum bottom plate 4 can be provided with the slot 9, and the contact area between the aluminum bottom plate and the iron layer can be further increased for fastening when the iron layer is sprayed.

The above-described embodiments are intended to suggest that, in view of the above description, various changes and modifications may be made by the worker without departing from the spirit of the invention. The technical scope of the present invention is not limited to the description, but the scope of protection must be determined according to the scope of claims.
