Description

Manufacturing method of an energy-saving pot with fins on the bottom of the pot

technical field

The invention relates to a pot, in particular to an energy-saving pot with fins on the bottom of the pot. Specifically, it also relates to a method for manufacturing an energy-saving pot with fins on the bottom of the pot.

Background technique

The technology of enlarging the surface area of the bottom of the pot adopted in the prior art is to design the metal with fins on the bottom of the pot, or the fins are very thick, the heat absorption effect is not good, and the weight is too heavy to make the operation extremely inconvenient. Either the fins are very thin and wide, the surface area is increased, and the heat energy acting on the bottom of the pot has been dissipated in essence. Furthermore, the process is complicated, the cost performance is not high, and it cannot be used on an induction cooker.

Contents of the invention

The object of the present invention is to provide an energy-saving pot with spiral fins at the bottom of the pot, which has a large surface area, is simple to manufacture, is energy-saving and durable, and can be used on an induction cooker. The object of the present invention is also to provide a manufacturing method of an energy-saving pot with fins on the bottom of the pot.

In order to achieve the above object, the present invention has the following technical solutions:

An energy-saving pot with fins on the pot bottom of the present invention comprises a pot body, wherein, the bottom of the pot body is provided with a heat conduction protection ring and at least one spiral fin, and the spiral fin is inserted into the heat conduction protection ring. The heat conduction protection ring and the spiral fins are welded on the bottom of the pot body, the thickness of the spiral fins is 0.3 to 1.5 mm, the height is 1 to 8 mm, and the wall thickness of the heat conduction protection ring is 1 to 10 mm.

Wherein, the helical fins are composed of magnetically conductive metal strips or other metal strips, and the pitch of the helical fins is 1 mm to 8 mm.

Wherein, the surface of the spiral fin and the bottom of the pot are sprayed with black or dark substances.

A method for making an energy-saving pot with fins at the bottom of the present invention has the following steps:

First, the spiral fins are stamped and formed at one time, and the spiral fins are leveled, then the spiral fins are coiled into a spiral shape, and then the spiral fins are inserted into the heat conduction protection ring, and the spiral fins and heat conduction protection ring are passed through high-frequency brazing The heat conduction protection ring and the bottom of the pot are connected together by high-frequency brazing.

Owing to taking above technical scheme, the advantage of the present invention is:

1. The surface area of the bottom of the pot body of the present invention is large, the heat absorption area is large, and energy is saved.

2. The thickness of the spiral fins of the present invention is 0.3 to 1.5 mm, the height is 1 to 8 mm, the weight is suitable for human use, and the operation is simple and durable, and can be used on an induction cooker.

3. The present invention is easy to manufacture, and is convenient for batch production and popularization.
