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 iron pan, pot body material are the pig iron or wrought iron, and heat transfer efficiency is not high, and local height is easy to produce in heating process
Temperature, when culinary art, are easy to produce oil smoke.Part iron pan can the bottom of a pan be arranged the even thermosphere that is made into of one layer of higher material of thermal conductivity and
The multiple bottom that one layer of magnetic conductive metal is constituted, the problem of being also easy to produce oil smoke so as to improve iron pan.But irony pot body usually require into
Row nitriding antirust treatment makes pot body be not easy to get rusty to promote pot body antirust ability.In nitriding process, because temperature is relatively high,
Even thermosphere is easy expanded by heating and even melts, and multiple bottom is caused to be deformed, influence using.
Summary of the invention
The purpose of the invention is to overcome in existing iron pan due to endless hermetically sealed between multiple bottom and pot body and infiltration
Problem caused by multiple bottom is easily-deformable in nitrogen treatment process provides a kind of fume-less cooker tool and preparation method thereof.
To achieve the goals above, one aspect of the present invention provides a kind of fume-less cooker tool, and fume-less cooker tool includes pot body
With the multiple bottom for being formed in pot body inside and or outside, the multiple bottom welds together with the pot body, forms sealing knot
The surface of structure, the multiple bottom is covered with nitride layer.
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 inside/outside surface.
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 multiple bottom is located at the bottom of pot body, and the multiple bottom and/or the bottom of pot body are provided with
Reinforcing rib.
Preferably, the pot body includes the base formed by smart iron or cast iron and the nitrided iron that is covered in the substrate surface
Layer.
Preferably, the nitridation that the multiple bottom includes the base formed by smart iron or cast iron and is covered in the substrate surface
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: multiple bottom is seeped
Nitrogen processing, and by the obtained multiple backing weld by Nitrizing Treatment pot body inside and or outside, make the multiple bottom with
Sealing structure is formed between the pot body.
Preferably, the method also includes: before it will answer bottom and pot body welding, the edge vehicle of the multiple bottom is fallen
Then a part is welded with removing nitride layer.
Preferably, the process of the welding is laser welding.
Preferably, the method also includes: between the multiple bottom and the inner surface of pot body form even thermosphere.
Have according to fume-less cooker of the present invention, pot body and multiple bottom form sealing structure, so as to prevent using
In the process in the infiltration and manufacturing process of water when cookware unitary fluid nitriding nitriding liquid infiltration, and multiple bottom have it is higher
Intensity, can prevent multiple bottom from deforming during Nitrizing Treatment.
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.
