Abstract

A pan bottom welding structure of an electric pan belongs to the technical field of domestic electric kitchen utensils. The pan bottom welding structure comprises a pan body and a uniform heating disc. A plurality of through holes are arranged on the uniform heating disc, a plurality of stainless steel spot nails are arranged on the external side of the bottom of the pan body by spot welding, and the uniform heating disc penetrates through the spot nails and is welded on the external side of the bottom of the pan body. The utility model is characterized in that the maximum diameter of the spot nails is slightly smaller than that of the through holes, and rivets are also arranged in the through holes. Compared with the prior art, the utility model has the advantage of simpler technique by saving aluminium riveted pipe on the condition that the uniform heating disc and the pan bottom have the same firmness with the prior art.

Description

A kind of electric food warmer the bottom of a pan Welding Structure

Technical field

The utility model belongs to domestic electric heating cooker technical field, is specifically related to a kind of electric food warmer the bottom of a pan Welding Structure.

Background technology

For solving the stainless steel electric food warmer uneven problem of conducting heat, often adopts the equal backing of compound layer of aluminum matter in the prior art in the bottom of a pan, equal backing with the mode of binding agent or welding and stainless-steel pan at the bottom of applying.Because no matter the difference of two kinds of material thermal conductivity factors is welding or bonding, when dry combustion method above 400 ℃ or long-time the use, all backing comes off easily.

For solving the equal backing problem that comes off, notification number is that the Chinese patent of CN100423673C discloses a kind of pot possessing composite bottom and manufacture craft, compound for one between its bottom of pot body and the Soaking disk by the riveting set back soldering that presses, riveting set is included in a plurality of some nails of bottom of pot body outside electric welding, on the Soaking disk with some the nail a corresponding through hole, be with the aluminium riveted pipe between Soaking disk through hole and the some nail, spot welding a bit pot body, aluminium riveted pipe, the Soaking disk pressing riveted joint back soldering of nail is integral.The content of this patent disclosure near prior art, is incorporated in this as the application.The application is the continuation improvement to above-mentioned patent.

Summary of the invention

The utility model provides a kind of electric food warmer the bottom of a pan Welding Structure, has simplified the Welding Structure of prior art, makes the electric food warmer manufacture craft simple more, effective.

The following technical scheme of the concrete employing of the utility model:

A kind of electric food warmer the bottom of a pan Welding Structure, comprise a pot body, Soaking disk, have a plurality of through holes on the Soaking disk, the bottom of pot body points outside is welded with a plurality of stainless steel point nails, Soaking disk crossing point tack welding is connected on the bottom of pot body outside, it is characterized in that some nail maximum gauge is more smaller than through-hole diameter, also is provided with rivet in through hole.

The material of pot body and some nail is a stainless steel, and the material of Soaking disk is an aluminium, and the some nail is evenly distributed on pot body.

Manufacture craft of the present utility model comprises the steps:

1) Soaking disk shaping punching;

2) bottom of pot body spot welding point nail;

3) bottom of pot body coated with solder;

4) Soaking disk is installed;

5) riveted joint;

6) soldering.

Compared with prior art, the utility model has the advantages that and omitted the aluminium riveted pipe, more succinct on the technology, and the firmness in the Soaking disk and the bottom of a pan is same as the prior art.

Description of drawings

Fig. 1 is the structural representation in the utility model electric food warmer the bottom of a pan;

Fig. 2 is Figure 1A portion enlarged diagram.

Among the figure, 1-pot body, 2-Soaking disk, 3-point nail, 4-through hole, 5-rivet.

The specific embodiment

Embodiment

As shown in Figure 1, a kind of electric food warmer the bottom of a pan comprises pot body 1, Soaking disk 2, has a plurality of through holes 4 on the Soaking disk 2, and Soaking disk 2 is welded on pot body 1 bottom outside;

As shown in Figure 2, Soaking disk 2 is by through hole 4 crossing points nail 3, and some nail 3 is more smaller than through hole 4 diameters, and requirement can be passed and ease of assembly gets final product.In through hole 4, also be provided with rivet 5.

The utility model has compared with prior art omitted the aluminium riveted pipe, has simplified the processing step of assembling.

Claims

1. electric food warmer the bottom of a pan Welding Structure, comprise a pot body, Soaking disk, have a plurality of through holes on the Soaking disk, the bottom of pot body points outside is welded with a plurality of stainless steel point nails, Soaking disk crossing point tack welding is connected on the bottom of pot body outside, it is characterized in that some nail maximum gauge is more smaller than through-hole diameter, also is provided with rivet in through hole.
