Aluminum pan

Abstract

The invention relates to an aluminum pan. The lower surface of the bottom of the aluminum pan is a composite surface and is provided with an accommodating groove. The aluminum pan comprises a magnetic conduction heating plate made of a plate with upward flanged holes, and is characterized by also comprising a metal connecting plate and an aluminum plate, wherein upward flanged holes and downward flanged holes are distributed on the surface of the metal connecting plate; the size and the shape of the aluminum plate are matched with those of the accommodating groove; the aluminum plate and the metal connecting plate are filled in the accommodating groove from bottom to top, the upward flanged holes of the metal connecting plate are connected with the bottom of the accommodating groove, and the downward flanged holes of the metal connecting plate are connected with the aluminum plate; the magnetic conduction heating plate is larger than the accommodating groove, at least one circle of flanged holes are fixedly connected with the bottom of a pan body while the magnetic conduction heating plate is fixedly connected with the lower surface of the aluminum plate through the flanged holes;and a structure that the lower magnetic conduction heating plate is arranged opposite to the upper metal connecting plate is adopted, so the thermal stress caused by different materials of the magnetic conduction heating plate and the aluminum pan body can be effectively eliminated, the defect that the bottom of the pan with the composite bottom is easy to deform after being heated is overcome, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of tableware pots, in particular to a composite pot bottom of an aluminum pot. Background technique [0002] Because aluminum is a non-magnetic material, traditional aluminum pots are not suitable for use on induction cookers. In response to the above-mentioned current situation, a composite pot bottom for aluminum pots has appeared in the market. One of them is to use it on the original aluminum pot bottom. A layer of stainless steel bottom surface is combined, and the bottom surface is welded to the bottom of the pot. The disadvantage is that the processing technology is complicated, and the steel plate needs to be welded to the bottom of the aluminum pot. The welding requires a special convex preparation, and it is easy to affect the surface of the bottom of the pot. smoothness, and the cost of welding is also higher. There is also a Chinese utility model patent "Composite Pan Bottom of Aluminum Pot" tha...

AI Technical Summary

Problems solved by technology

The composite pot bottom has the advantages of simple processing, low cost, and relatively firm connection. However, since the magnetically conductive heating plate is compositely fixed on one side of the pot body, the pot body and the magnetically conductive heating plate are made of different materials. In the case of expansion and contraction, thermal stress is likely to occur, resulting in convex or concave deformation of the bottom of the pot, especially if the bottom of the pot is convex, it will cause many dangerous factors, such as unstable rotation, causing hot objects in the pot to hurt people , so it is necessary to further modify
