The interior pot of manufacture according to the first embodiment of the present invention for electric cooking apparatus is described below in reference to Fig. 3
Method:
Step 1 first forms the body construction of interior pot with ceramic material.
It specifically, in step 1, can successively include following procedure: first by clay and spodumene, other special ores
(different according to the demand of internal pot, various ore compositions are also different) etc. are stirred concise at mud by special equipment, and are divided into
Column clod (at mud step)；Secondly pottery mud is put into plaster mold, goes out the pot gallbladder shape (mould needed with spinning or extrusion forming
Step processed)；Then mould overlap and sharp edge is divided to fix (repaired biscuit step) on mold extra on the pot gallbladder of forming；Then by interior pot
It is put on wind room or level land, air-dries and dry, reduce the moisture content (air drying steps) in greenwave；By the polishing of greenwave surface, finishing, make table
Face is finer and smoother, and appearance is more good-looking, and size is more precisely (mill blank step)；Wind room is dried again, the moisture content in greenwave is reduced, to subtract
Moisture content when being sintered less；Internal pot carries out high temperature sintering (about 800 DEG C or more), it should be noted that sintering refers to hot conditions
Under, billet surface product reduces, the densification process (biscuiting step) that porosity reduces, mechanical performance improves；Then verify that interior pot
Size selects the greenwave of size qualification to execute subsequent step.
Preferably, after step 1, it attached can be painted a layer of glaze by glaze spraying or leaching glaze etc. forms in the inner surface of greenwave
Layer, is then sintered under 1000 DEG C or more of hot environment, makes glaze layer high temperature crystallization.
Then step 2 can be executed, blasting treatment is carried out to the predetermined position of the outer surface of greenwave, reaches first
Predetermined roughness.The predetermined position is the position for needing to be arranged magnetic conductive metal layer.First predetermined roughness is 8-12 μm, such as
9 μm or 10 μm.After blasting treatment, by interior pot cleaning, drying, with the greasy dirt, dust, soft layer etc. for removing surface, in order to
Subsequent processing.
Then step 3 is executed, forms magnetic conductive metal layer in the outer surface of the greenwave after step 2 processing.It uses
Such as ferromagnetic material, aerdentalloy or silver etc. can be generated the permeability magnetic material meltallizing of electromagnetic induction to the pottery of interior pot by meltallizing equipment
The predetermined position of the outer surface of porcelain ontology, to form magnetic conductive metal layer.In the present embodiment, which is bottom wall
With the outer surface of connection wall.Therefore, in step 2 above, can the outer surface only to bottom wall and connection wall do at sandblasting
Reason.Preferably, the thickness of magnetic conductive metal layer can be 0.1~0.3mm.

Reason, reaches third predetermined roughness.The third predetermined roughness is 2-6 μm, according to the demand of technique, can be 3 μm, 4 μ
M or 5 μm.After blasting treatment, interior pot cleaning, drying is reduced into attachment with the greasy dirt, dust, soft layer etc. for removing surface
The risks such as coating shedding peeling.Then non-sticking lining is formed in the inner surface of the glaze layer of pot wall.Non-viscous paint is passed through cold
The mode of spraying is attached on the inner surface of the glaze layer of pot wall inner surface, then makes the close knot of the two by high temperature sintering
It closes, to realize not viscous function.
Or protective coating can also be formed by trypsin method, protective coating is formed in the outermost of pot wall.Outside to pot wall
At least magnetic conductive metal layer part of side surface carries out blasting treatment, reaches the 4th predetermined roughness, the magnetic conduction after making meltallizing
The surface fine of metal layer to increase its fine and smooth degree, while removing meltallizing oxidation on metal surface layer.4th predetermined roughness
Substantially 2-12 μm.According to appearance and the demand of subsequent processing, which can be 3 μm, 5 μm, 7 μm, 8 μm, 9 μm or 11
μm.Then the wear-resistant paint of silicone resin or fluororesin etc. is attached to the outer surface of pot wall by cold spraying form.And pass through height
Temperature sintering is allowed to be attached to the outside of pot wall well, plays a protective role, and enhances antirust, anti-corrosion, the wear-resisting performance of interior pot, prolongs
Its long service life.Protective coating material should be at least covered on the outer surface of magnetic conductive metal layer.In the present embodiment, it protects
Protect whole outer surfaces of coating covering pot wall.
It is to be appreciated that above embodiment is a kind of embodiment of pot in manufacturing, wherein each step is not necessarily all
It is necessary, one or more of steps can be increased or decreased according to demand；Also, the sequence of each step is also not necessarily
Be so it is fixed, its successive operation order can be adjusted according to demand.Such as the sequence of interior spraying process and trypsin method step can
With reverse.
Hereafter other preferred embodiments according to the present invention are briefly described, it should be noted that hereinafter will
The other embodiment to be described is roughly the same with above-mentioned embodiment, therefore for sake of simplicity, is only said to difference
It is bright.
