Description
Technical field
The present invention relates to cooking apparatus fields, more particularly to a kind of fume-less cooker tool and preparation method thereof.
Background technique
Traditional cookware generally uses single layer structure, and usually pot body thickness is made than relatively thin to save cost.Because of material
It is thin, it will lead to the problems such as pot body is easily-deformable, and the bottom of a pan uneven heating is even.Part cookware can increase single-layer or multi-layer in the bottom of a pan and answer bear building-up
Structure, to realize the pot body structure of thick bottom thin-walled, neither will increase too many cost again can significantly improve the problem of pot bottom deforms,
And answering bottom by increase magnetic conduction can enable non-magnetic pot body heat on electromagnetic oven.But multiple bottom is normally located at pot
External side, through modes such as welding, cold rivetings in conjunction with pot body.In cookware use process, multiple bottom Direct Contact Heating source, when long
Between operation or repeatedly cooling thermal impact at high temperature, be easy to appear the problem of multiple bottom falls off.And external multiple bottom usually with pot
Blow-by between body, in cleaning process, water is easily infiltrated into multiple bottom, influence using.
Summary of the invention
The purpose of the invention is to overcome in existing iron pan multiple bottom that can directly contact with heating source and multiple bottom and
Between pot body it is endless it is hermetically sealed caused by problem, a kind of fume-less cooker tool and preparation method thereof is provided.
To achieve the goals above, one aspect of the present invention provides a kind of fume-less cooker tool, wherein the fume-less cooker, which has, includes
Pot body and the multiple bottom being formed on the inside of pot body, the multiple bottom weld together with the pot body, form sealing structure.
Preferably, the multiple bottom forms sealing structure by laser welding with the pot body.
Preferably, the fume-less cooker tool further includes even thermosphere, and the even thermosphere is located at the multiple bottom and the pot body
Between inner surface.
Preferably, the pot body outwardly convex forms groove, and the even thermosphere is located in the groove, the multiple bottom
The wall surface of thickness edge and the groove is interference fitted, the upper surface of the multiple bottom and the smooth interior surfaces mistake of the pot body
It crosses.
Preferably, the structure type that the multiple bottom and the bottom of pot body are formed is outer flat indent, outer Ping Neiping, evagination
It is put down in concave or convex.
Preferably, the material of the pot body is smart iron, cast iron, stainless steel or aluminium
Preferably, the material of the multiple bottom is smart iron, cast iron, stainless steel or aluminium.
Preferably, when the material of the pot body and the multiple bottom is smart iron or cast iron, the pot body and the multiple bottom
The outer surface of layer is covered with nitridation iron layer.
Preferably, the material of the even thermosphere is aluminium and/or copper.
Second aspect of the present invention provides a kind of preparation method of fume-less cooker tool, this method comprises: logical in the inside of pot body
It crosses welding and forms multiple bottom, and the multiple bottom and the pot body is made to form sealing structure.
Preferably, the method also includes: before forming the multiple bottom, form even heat in the inside of the pot body
Layer.
Preferably, the method also includes: after forming sealing structure between the multiple bottom and the pot body, to whole
A cookware carries out Nitrizing Treatment.
Preferably, the multiple bottom is linked together with the pot body by laser welding.
Have according to fume-less cooker of the present invention, multiple bottom will not be contacted directly with heating source, i.e., in the inside of pot body
Make to heat repeatedly and be also not easy to fall off with cooling thermal impact, cookware service life can be improved；Moreover, pot body and multiple bottom shape
At sealing structure, so as to prevent the infiltration of water in use process, and (such as when the pot body is needed by Nitrizing Treatment
When pot material is smart iron or cast iron), the infiltration of nitriding liquid when can prevent cookware unitary fluid nitriding in manufacturing process, together
When can also prevent the aluminium of melting during high temperature nitriding from leaking out.
In the preferred case, the welding manner between multiple bottom and pot body is laser welding.Compared with common welding manner,
It can accomplish to be fully sealed by the way of laser welding, even if so that the sealing structure between multiple bottom and pot body is seeped in high temperature
When stretcher strain occurs for bottom and pot body again during nitrogen, still it will not crack at soldering opening, so as to prevent from making
The infiltration of cookware nitriding liquid enters from soldering opening during making, while being also possible to prevent the aluminium of melting during high temperature nitriding
(because of high temperature nitriding, the fusing point of aluminium is relatively low) leaks out from soldering opening.Moreover, to be formed by welding surface welding trace equal for laser welding
Even, the molten region of hurting of welding is small, without apparent crator, preferable appearance can be obtained after welding, following process is not needed to welding position
Do specially treated.
