Embodiment 1

[0037] As shown in Fig. 1, Fig. 2 and Fig. 3, the energy-saving cooking appliance includes a cooker wall 3 and a cooker bottom 4 integrally connected with the cooker wall 3 for being heated.

[0038] The outer surface of the cooker bottom 4 is fixed with a corrugated metal sheet 1, and the metal sheet 1 and the cooker bottom 4 are combined together by hot forging or brazing. Sheet 1 is made of ferrite or martensitic stainless steel with strong magnetic flux capability. And the corrugated shape of the metal sheet 1 is a plurality of concentric circular structures with the center of the metal sheet 1 as the center.

[0039] It can be seen that the corrugated metal sheet 1 expands the area of ​​the cooker bottom 4 for receiving electromagnetic waves, and can effectively absorb the electromagnetic energy converted from electric energy and convert it into heat energy, thereby improving the utilization rate of electric energy.

[0040] As shown in FIGS. 4 and 5 , both sides of the ...

Embodiment 2

[0042] As shown in Fig. 6 and Fig. 7 and Fig. 8, the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that a metal plate 2 is arranged between the bottom 4 of the cooker and the metal sheet 1, and the described The outer surface of the metal plate 2 has a corrugated shape with the same shape and size as that of the metal sheet 1. Between the metal sheet 1 and the metal plate 2, and between the metal plate 2 and the bottom of the cooker 4, heat forging or brazing is used. The metal plate 2 is made of aluminum, and the metal plate 2 plays the role of heat conduction and anti-corrosion.

Embodiment 3

[0044] As shown in Fig. 9 and Fig. 10 and Fig. 11, the structure and principle of the present embodiment are basically the same as those of the second embodiment, the difference is that the corrugated shape of the metal sheet 1 is in the shape of dot-like concavo-convex or strip-shaped concavo-convex on the bottom surface, And take the center of the metal sheet 1 as the starting point to form an outward-emitting structure. Of course, the outer surface of the metal plate 2 also has corrugations of the same shape and size as the metal plate 1 or the bottom 4 of the cooker.

Abstract

An energy-saving cooker is composed of a main body consisting of wall and bottom, and a corrugated metallic plate fixed to the external surface of said bottom for increasing the electromagnetic wave receiving area, so saving electric energy.

Description

technical field [0001] The invention relates to kitchen utensils, in particular to an energy-saving cooking utensil applied to an electromagnetic oven. technical background [0002] The existing cooking utensils, especially the cooking utensils applied to the induction cooker, because the pot body of the cooking utensils is usually made of aluminum or stainless steel, absorbs relatively small electromagnetic waves emitted by the induction cooker, resulting in low thermal efficiency of the cooking utensils during use. , high power consumption, long cooking time and other defects. [0003] In order to overcome these defects, someone has designed a cooking utensil with a composite structure at the bottom, which adds a layer of stainless steel material with strong magnetic flux capability at the outer bottom of the pot body, thereby improving the receiving capacity of electromagnetic waves. Obviously, the cooking utensil with such a structure can be heated quickly and the cooki...
