Abstract
The utility model belongs to the technical field of electric heating cooker, and particularly relates to a riveting and welding combined multiple-bottom electric food warmer which comprises a pot body. A welded base plate is welded on the bottom of pot body. The riveting and welding combined multiple-bottom electric food warmer is characterized in that a riveting and welding combined device is further arranged between the pot body and the base plate. The pot body and the base plate are combined together through a riveting and welding device, and thereby overcoming defects of an ordinary multiple-bottom electric food warmer that the base plate and the pot body are connected together only via welding, the base plate and the pot body are prone to separating caused by non-synchronous expanding or contracting when two materials are heated or cooled down, and thus service life of multiple-bottom electric food warmer is short. The riveting and welding combined multiple-bottom electric food warmer has the advantages of being secure in connection between the base plate and the pot body, not easy to separate, uniform in heating and not easy to paste pot, and long in service life.

The utility model is achieved through the following technical solutions:
Be a kind of rivet welding combination electric food warmer of the multiple end, comprise a pot body, bottom of pot body is provided with the chassis of welding, it is characterized in that also being provided with between pot body and the chassis rivet welding coupling apparatus, and pot body and chassis link together by the rivet welding coupling apparatus.
As a preferred version of the present utility model: described rivet welding coupling apparatus comprises hollow rivet-welding nail and solid weldering nail, described hollow rivet-welding nail is fixedly mounted on the bottom of pot body, the chassis is provided with the through hole with hollow rivet-welding nail coupling, and solid weldering nail inserts in the hollow rivet-welding nail chassis and pot body rivet welding are combined.
As a preferred version of the present utility model: the cross sectional shape of hollow rivet-welding nail is circular or square or triangle, the cross sectional shape of described solid weldering nail and the cavity cross section form fit of hollow rivet-welding nail.
As a preferred version of the present utility model: the rivet welding coupling apparatus is solid rivet-welding nail, and described solid rivet-welding nail is fixedly mounted on the bottom of pot body, and the chassis is provided with the through hole with solid rivet-welding nail coupling.
As a preferred version of the present utility model: the cross sectional shape of solid rivet-welding nail is circular square or leg-of-mutton.
As a preferred version of the present utility model: bottom of pot body is provided with 1 hollow rivet-welding nail at least.
As a preferred version of the present utility model: bottom of pot body is provided with 1 solid rivet-welding nail at least.
According to the size of pot body, bottom of pot body can be provided with 1 or 2 or 3 or 4 or more hollow rivet-welding nail or solid rivet-welding nails, and the chassis is provided with the through hole that matches.
The bottom of a pan of the present utility model can be flat also can be arcuate bottom, chassis shape and the bottom of a pan are complementary.
Chassis of the present utility model combines with the pot body by soldering and two kinds of methods of rivet welding, only link together by soldering between the chassis that has overcome electric food warmer of the common multiple end and pot body, because bi-material is heated, it is asynchronous to expand when cooling off, shrink, cause the chassis easily separated with the pot body, cause the short defective in service life of electric food warmer of the multiple end, this is practical have advantages of between chassis and pot body be connected firmly, not easily separated, be heated evenly should not be burned, long service life.
