But following hole density value is more suitable: hole density is 10% on around the endless belt in central annular district; Hole density is 25% on the intermediate annular band; Hole density is 20% on the endless belt of periphery, the bottom of a pan.
According to optimum principle, the thickness of built-in aluminium flake approximately is 5mm, and the thickness of external stainless steel substrates approximately is 0.5mm.
Around 90% hole on the endless belt in central annular district is circular better.
According to optimum principle, middle and peripheral endless belt is made up of the angled region that replaces.One group of angled region is made up of slotted eye; Another group angled region is made up of circular hole.
According to optimum principle, the major axis dimension of slotted eye is along with from the increase of the bottom of a pan centre distance and increase.
Circularhole diameter is better as being lower than 0.015 times of the bottom of a pan diameter.
The diameter that advantage of the present invention is embodied in central annular district equals 1/4th times of the bottom of a pan diameter.
The endless belt peripheral diameter that centers on central annular district is 0.4-0.5 a times of the bottom of a pan diameter.
According to optimum principle, the peripheral diameter of intermediate annular band is that the 0.7-0.8 of the bottom of a pan diameter is doubly better.
According to optimum principle, except that central annular district, surface, the bottom of a pan can not have any diameter to surpass the annular region that does not have the hole of 15mm.
After the description below having read, you can better understand the present invention.Simultaneously, you also can be with reference to additional drawing (samples of this drawing do not have in shape restricted).

The thickness of aluminium lamination 1 is 5mm.
The thickness of stainless steel layer 2 is 0.5mm.It has the depression central authorities annular district 4 of repressed formation, and cup depth is approximately 1mm, and cross section is 50mm
2This sunk structure that is formed by punching press can make aluminium be expressed to outer peripheral areas.There is not hole in the central authorities annular district 4.
The annular band that central authorities annular district 4 is made up of slotted eye and circular hole is around forming.Though the density in hole and increase and decrease scope thereof are very limited, we still can make many variations to the shape and the arrangement in hole for aesthetic consideration.
First endless belt 6 around central annular district 4 mainly is made up of circular hole, and each circular hole has the diameter of 2.6mm; The minor axis of slotted eye approximately is 2.3mm, and major axis approximately is 10mm.77 circular holes and 7 slotted eyes are arranged in first endless belt, and external cross section is 84mm
2The density of the aluminium that squeezes out in first endless belt is 10.77%.
The hole density of intermediate annular band 7 approximately is 24.77%.It is arranged by three donuts and forms, and each annulus is made up of 7 slotted eyes that size increases gradually.In 2 angled region forming by 3 slotted eyes, the circular hole that to have 7 diameters are 2.6mm.Like this, always have 21 slotted eyes and 49 circular holes in the intermediate annular band.The minor axis dimension of slotted eye is respectively 3.2/3.7/3.8mm, and major axis dimension is respectively 23/30/36mm.
The 3rd peripheral annular band 8 also is to be arranged by three donuts to form, and each annulus is made up of 7 slotted eyes that size increases gradually.In two angled region, 3 slotted eyes of arranging are radially arranged.The minor axis dimension of these slotted eyes is respectively 4/4.2/4.2mm, and major axis is respectively 42/47/50mm.
The hole density of the 3rd peripheral annular band 8 approximately is 21%.
In used term of the present invention, " ellipse " is used for describing one and is similar to oval-shaped surf zone.It approaches described geometrically " ellipse ", and still, the definition about " ellipse " is not followed geometrically in strictness, and promptly the distance on any point to two fixing point from the ellipse has identity.But this does not influence the use in the present invention of " ellipse " term.
Kitchen tools bottom among the present invention is specially adapted to the heating of dissimilar stove and accessorys.
-gas stove and accessory, if correctly adjust flame, flame kernel just in time is positioned at the middle circle annulus of kitchen tools bottom.
-electromagnetic induction stove and accessory can add at the bottom of the pyromagnetic stainless steel.
-ceramic hot plate can pass through aluminium hole heated convection.
