Layer 26.
In another embodiment, the contrast colot layer 23 and the photochromic layer 26 are formed on the same face side by side, and
It is formed directly on the inner surface of the substrate 10.In this case, on the inner surface of the substrate 10, contrast colot layer 23
There is no particular limitation with the arrangement mode of photochromic layer 26.Contrast colot layer 23 and photochromic layer 26 can contact with each other, can also be mutual
Separation.Contrast colot layer 23 and photochromic layer 26 can be formed in the regional area of 10 inner surface of substrate, can also both cover base together
The entire inner surface at bottom 10.In the preferred case, the contrast colot layer 23 is formed around the surrounding of the photochromic layer 26.Further
Preferably, the inner circumferential of the contrast colot layer 23 is covered on the periphery of the photochromic layer 26.
In a preferred embodiment, the contrast colot layer 23 and the photochromic layer 26 cover 10 inner surface of substrate
Regional area, other regions of 10 inner surface of substrate are formed with priming coat 21 namely contrast colot layer 23, photochromic layer 26 and bottom
21 three of coating covers the entire inner surface of substrate 10 together.It is further preferred that on the inner surface of substrate 10, photochromic layer 26
It is formed in centre, contrast colot layer 23 is formed around the surrounding of photochromic layer 26, and priming coat 21 surrounds the surrounding shape of contrast colot layer 23
At.Preferably, the inner circumferential of contrast colot layer 23 is covered on the periphery of photochromic layer 26 a more progressive step, and the inner circumferential of priming coat 21 is covered on
On the periphery of contrast colot layer 23.
In the heating utensil, in one embodiment, the heating utensil further includes being formed in the heater
Has the transparent surface coating 28 of the innermost layer of inner surface.In this embodiment, contrast colot layer 23, photochromic layer 26, optional priming coat
21 and optional floating coat 24 be both formed between substrate 10 and transparent surface coating 28.
In the present invention, the priming coat 21 and the floating coat 24 are respectively preferably black.In this case,
The priming coat 21 and/or the floating coat 24 can further serve as the effect of contrast colot, so that user focuses more on lining
The variation of chromatograph 23 and 26 color of photochromic layer.
In the present invention, the priming coat 21 can be formed by the dark base oil of this field routine, the dark color bottom
Oil can for example contain polytetrafluoroethylene (PTFE) and black pigment.
In the present invention, the floating coat 24 can be formed by oil in the dark color of this field routine, in the dark color
Oil can for example contain polytetrafluoroethylene (PTFE) and black pigment.
In the present invention, the transparent surface coating 28 can be formed by heat-resisting, the transparent material of this field routine, example
It can such as be formed by polytetrafluoroethylene (PTFE).
In the heating utensil, in one embodiment, the photochromic layer 26 is configured to text or pattern, institute
The gross area for stating contrast colot layer 23 is greater than the gross area of the photochromic layer 26, and the amplitude of the color change of the contrast colot layer 23 is less than institute
State photochromic layer 26.Design in this way can make photochromic layer 26 merge with contrast colot layer 23 when being heated to preset temperature, produce
The effect that the chromatograph 26 that changes disappears, thus the time for reminding people to drain the oil.
In the heating utensil, in one embodiment, the center of the substrate 10 raises upward, the photochromic layer
26 are located at the upper surface of boss.In this case, since photochromic layer 26 is in a high position, substrate table is protruded from slightly
Face, oil or sauce when being not easy in this way by cooking are covered, can be more easily observed by user.
In the heating utensil, in one embodiment, the heating utensil is frying pan, and the substrate 10 includes iron
Outer layer and aluminium internal layer, the contrast colot layer 23 and/or the photochromic layer 26 are formed on the aluminium internal layer and are located at the frying pan
Middle part.In the centre of frying pan, discoloration is easiest to be observed, but when being heated on electromagnetic oven, due to electromagnetism
The reason of furnace induction coil coiling (electromagnetic oven center is not wound with induction coil), the portion opposite with frying pan center is allowed in this way
Position induction coil missing, and spot temperature directly opposite with induction coil is excessively high that (this is also why at the bottom of a pan radius 1/2
Be easy the reason of burning), the heat transference efficiency of iron be it is very low, by adding aluminium internal layer, can the bottom of a pan and induction ledger line circle
The heat transfer of opposite site to the bottom of a pan center, enable photochromic layer much sooner, accurately, be truly reflected the temperature at the bottom that takes the dish out of the pot
Degree.
In the preferred case, thick centered on the aluminium internal layer and from center week gradually thinning structure outward.In this way
Design so that heat as far as possible toward pot center pass on, further improve frying pan discoloration accuracy and timeliness.
In the preferred case, the iron outer bottom has the circular through hole of hollow out, and the aluminium internal layer is squeezed protrusion
In in the through-hole, the upright projection of at least one through-hole is located at the contrast colot layer 23 and the photochromic layer 26 is constituted
Region in.On the one hand design in this way can increase the contact area of aluminium internal layer Yu iron outer layer, the heat of iron outer layer
It is promptly transmitted in pot, so that discoloration is more accurate and timely；On the other hand when frying pan is placed on heated on gas stove when
It waits, the firepower at gas stove center can be directly passed to off-color material by the aluminium layer in the through-hole opposite with color change interval, from
And further improve the accuracy and timeliness of frying pan discoloration.
In the present invention, the contrast colot layer 23 and the photochromic layer 26 can respectively pass through the method for this field routine
It is formed.In the preferred case, the contrast colot layer 23 is formed by way of spraying, and the photochromic layer 26 passes through mode of printing shape
At.The area of contrast colot layer 23 is larger, is formed by way of spraying, can be more uniform be coated on substrate or priming coat,
26 area of photochromic layer is smaller, more efficient by mode of printing.
