Problems solved by technology

In addition, when the film is heated, a large stress perpendicular to its radius will be generated, and if it is not shunted, it will easily lead to deformation
[0004] The metal sheet at the bottom of cooking utensils of other structures cannot completely solve the known problem of sudden expansion and / or deformation of the bottom

Embodiment 1

[0024] Such as figure 1 As shown, the complex bottom sheet of the magnetic induction heating cooker is arranged at the bottom of the cooker, and includes a sheet body 1 made of a magnetically conductive material. In this embodiment, the sheet body 1 is made of stainless steel. The sheet body 1 is made of a sheet material, and a central hole 10 is hollowed out in the center of the sheet material, and the entire sheet body 1 is circular. The outer edge of the sheet body 1 is provided with a plurality of outer through holes opening toward the outside and extending inward, and the inner edge of the sheet body 1 is provided with a plurality of inner through holes opening toward the inner side and extending outward.

[0025] Such as Figure 1-3 As shown, the outer through-holes include several arc-shaped outer through-holes 21, and the above-mentioned arc-shaped outer through-holes 21 divide the entire sheet 1 into several lotus petal-shaped regions 4 and ginkgo leaf-shaped region...

Embodiment 2

[0028] Such as Figure 4 As shown, in this embodiment, the outer through holes include several straight outer through holes 22 uniformly distributed in the circumferential direction, and the inner through holes include several straight inner through holes 32 evenly distributed in the circumferential direction. Each straight outer through hole 22 and each straight inner through hole 32 are arranged alternately. The lengths of the straight outer through holes 22 are equal, the lengths of the straight inner through holes 32 are equal, and the sum of the lengths of a straight outer through hole 22 and a straight inner through hole 32 is equal to the width of the sheet body 1 . The rest are similar to those in Example 1, and will not be described in detail herein.

Abstract

The invention provides a compound bottom sheet of a magnetic induction heating cooker, belongs to the technical field of mechanics, and aims to solve the problem that a metallic sheet on the bottom part of the conventional cooker cannot completely avoid sudden swelling and / or deformation of the bottom part. The compound bottom sheet arranged on the bottom part of the cooker comprises a sheet body made of a magnetic conduction material, wherein the sheet body is circular ring-shaped; the outer edge of the sheet body is provided with a plurality of outer through holes of which the openings face the outer edge and which are extended inward, while the inner edge is provided with a plurality of inner through holes of which the openings are toward the inner edge and which are extended outward. The compound bottom sheet of the magnetic induction heating cooker has the advantages of little thermal expansion deformation, stable structure, difficult falling-off and long service life.

Description

technical field [0001] The invention relates to the technical field of machinery, relates to cooking utensils, in particular to a compound negative sheet for magnetic induction heating cooking utensils. Background technique [0002] Existing cooking utensils made of non-magnetic materials cannot be used in induction cookers. Some of the above-mentioned cooking utensils that can be used in induction cookers all use a layer of ferromagnetic stainless steel sheet on the bottom of the cooker to make aluminum pots and other non-magnetic cookers The cookware can also be used on induction hobs. Most of the time, a metal plate with good thermal conductivity is assembled on the bottom of the heating to transfer heat. However, the more layers of material with different structures on the bottom of the cookware, the more prone to harmful expansion and deformation for the heating action of the heater. Like this, just occur the long-term deformation of container especially the shedding ...
