Composite boiler and production method thereof

Abstract

The invention relates to a composite boiler comprising a boiler bottom, wherein the boiler bottom is formed by compounding a magnetic metal bottom plate and a metal substrate; the magnetic metal bottom plate is provided with a plurality of grooves; a fracture surface is at least arranged between the bottom wall and upper wall of the groove; a gap is arranged between the bottom wall and upper wallof the groove and on the fracture surface; no gap is provided on the positive projection direction of the magnetic metal bottom plate; and the metal substrate is filled in the gap on the groove and the fracture surface after being fused. The production method mainly comprises the following steps: setting a limited post; causing the inner wall of the front mould of a die-casting mould to prop against the top of the limited post after closing the die-casting mould; causing the other end of the limited post to prop against the magnetic metal bottom plate so as to be adhered to the inner wall of the back mould of the die-casting mould, thus effectively ensuring that the magnetic metal bottom plate is positioned on the lowest surface while casting is carried out and effectively receiving the heat energy generated by magnetic field radiation; the limited post and the metal substrate are made of the same material, which is beneficial for fusing the limited post and the metal substrate into awhole; and the combination is firmer. The area of the magnetic metal bottom plate is not reduced on the fracture surface so that the heat efficiency of an induction cooker is improved.

Description

technical field [0001] The invention relates to the structure and production method of cooking pots, in particular to the structure and production method of a composite pot with a composite magnetically conductive metal pot bottom. Background technique [0002] At present, most of the metal cooking utensils adopt the composite pot bottom structure, which not only has good heat transfer effect but also has reliable cooking quality; The thermal effect is good and the manufacturing cost is saved. Secondly, when the interchangeability of pots is considered, for example, pots used with open flames can also be used on induction cookers. These pots need to consider the structure of magnetically conductive composite pot bottoms. Pots with a composite pot bottom structure are generally composed of metal materials with different thermal or magnetic properties. Especially for composite pots used in induction cookers, generally ferrous materials with magnetic conductivity are composite...

Problems solved by technology

[0006] In order to solve the problem of combining two different metals together, so that the two are closely combined, it can not only conduct magnetism and generate heat, but also effectively conduct heat, and will not be deformed after a period of use due to the difference in expansion coefficient between the two, which will affect the heat transfer efficiency. , causing the problem of easy falling off
