Invention content
The purpose of the present invention is to provide a kind of cooking apparatus enamel liner, surfaces externally and internally be respectively provided with non-sticking lining and
Enamel glaze layer has the characteristics that few defect, good appearance and soft handle.
In order to achieve the above object, technical scheme is as follows：
A kind of cooking apparatus enamel liner, including cast iron courage body, the outer surface sintering of the cast iron courage body has enamel glaze
Layer, the inner surface of cast iron courage body are then coated with non-sticking lining, have radially outer flange, institute at the courage mouth of the cast iron courage body
State enamel glaze layer and non-sticking lining all extend to the flange, the outer end face of the flange respectively with the top and bottom of flange it
Between there is turning, the corner that the junction of the enamel glaze layer and the non-sticking lining is located therein.
The present invention is by the surface spraying non-sticking lining in cast iron courage body, to ensure non-stick of the liner in culinary art.
Appearance of the outer surface sintering enamel glaze layer of cast iron courage body to improve the corrosion resistance of cast iron courage body, improve liner.Due to enamel
Glaze layer needs high temperature sintering, therefore its manufacturing sequence is prior to non-sticking lining, wherein, enamel glaze layer of the present invention and non-sticking lining are equal
The flange is extended to, and the junction of enamel glaze layer and the non-sticking lining is located at the corner of the flange outer end face, i.e.,
Enamel glaze layer ends at the corner of flange, and due to flange outer end face just smaller, the height smaller of corner of height in itself, make
It obtains the irregularities that enamel glaze layer terminates to locate to be limited in the height region of a very little, i.e., is limited in defective region
In the region of one very little, the generation of defect is reduced, and the irregularities of corner are not easy to be easily noticed by the users, therefore can't shadow
Ring appearance.Furthermore enamel glaze layer ends at the corner of flange, and the bottom surface of flange is then covered by enamel glaze layer, and user is in hand rest
During flange, feel is preferable.In addition, the junction of enamel glaze layer and non-sticking lining is located at the corner of flange outer end face, do not lie in
Flange top surface is not closed by the lid of cooking apparatus cover, and steam etc. is difficult to contact and penetrates into the junction during culinary art, is increased
The corrosion resistance of liner.
In some of them embodiments of the invention, the turning between the outer end face and the top surface of flange is the first turning, institute
It states the position that enamel glaze layer is connected with the non-sticking lining and is located at first corner.Enamel glaze layer is extended to this first to turn
It at angle, so as to make the outer end face of entire flange and bottom surface, is covered by enamel glaze layer, non-sticking lining is avoided to extend to the outer of flange
On the outside of end face, the non-sticking lining when outer end face is scraped can be avoided to be scratched, and enamel glaze layer resists since hardness is higher
Scraping ability is strong, it is difficult to be damaged when being scratched.On the other hand, the feel of enamel glaze layer is thick and solid, good appearance, the vision of user
It experiences；User is in hand rest flange, outer end face that Toe Transplantation for Segmental Finger will touch flange, and feel is preferable.
In some of them embodiments of the invention, the turning between the outer end face and the bottom surface of flange is the second turning, institute
It states the position that enamel glaze layer is connected with the non-sticking lining and is located at second corner.Due to enamel glaze layer and the not snearing
The position of layer connection is located at second corner, makes the junction of enamel glaze layer and non-sticking lining downward, therefore even if
Gas leakage causes condensed water to be slid at flange during culinary art, and cast iron courage body will not be penetrated into from junction, is further increased
The corrosion resistance of liner.
In some of them embodiments of the invention, the turning of the enamel glaze layer and the non-sticking lining junction for chamfering or
Person's fillet.The turning is set as chamfering or fillet etc. has the structure of even surface, avoids enamel glaze layer and non-sticking lining
Junction is located at wedge angle position, so as to there are problems that easily being scratched；In addition enamel glaze layer and non-sticking lining all extend to down
On angle or fillet, when making, the junction of the two, which can be set, overlaps area, the intensity and level combined both so as to improve
Sense.Furthermore since the face of chamfering or fillet has a segment length distance, in the checkout procedure of making, observation can be passed through
Whether the enamel glaze layer of sintering extends upper chamfering or fillet, so as to judge the sintering of enamel glaze layer it is whether qualified and, observation is not
Whether adhesive coating layer extends upper chamfering or fillet, so as to judge whether the spraying of non-sticking lining is qualified.
In some of them embodiment of the invention, the height at the turning of the enamel glaze layer and the non-sticking lining junction is
0.3-1.0mm.Make powder injection molding in the range of 0.3-1.0mm height, in addition enamel glaze layer and non-sticking lining under the size
Bonding pad area is unlikely to too small, and exists and connect illusive problem.
In some of them embodiment of the invention, the non-sticking lining covers the enamel glaze layer in the corner.By
In enamel glaze layer to be sintered, the section planarization at end is poor, and non-sticking lining covers enamel glaze layer, prevents from putting down
The poor section of whole property is exposed, so as to avoid penetrating into for water etc..On the other hand, when liner is collided or fallen, most may be used
The region that can be collided is the corner of flange, although its very high quality of enamel glaze layer hardness is more crisp, scratch resistance is good
But not impact resistance, and the impact resistance of non-sticking lining is then better than enamel glaze layer, therefore is covered in corner's non-sticking lining
On the enamel glaze layer, when can improve liner and falling or collide, the anti-use collapsed porcelain ability, improve liner of the corner
Service life.
In some of them embodiment of the invention, the thickness that the non-sticking lining is covered in the enamel glaze layer is less than covering
In the thickness in cast iron courage body on wall, the thickness that the enamel glaze layer is covered on the junction turning, which is less than, is covered in cast iron
Thickness on the external wall of courage.Since the influence area for collapsing porcelain is related to its thickness, its smaller influence area of thickness is smaller, wherein institute
It states the thickness that enamel glaze layer is covered on the junction turning and is less than the thickness being covered on the external wall of cast iron courage, turned described
Using the smaller enamel glaze layer of thickness at angle, when surprisingly colliding, it can be reduced and collapse porcelain facing product, effectively prevent large area
Blackmail.In addition, the thickness that non-sticking lining is covered in the enamel glaze layer is less than the thickness being covered in cast iron courage body on wall, keep away

Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 to Fig. 3 is please referred to, for a kind of relevant indicators of cooking apparatus enamel liner embodiment one of the present invention.
With reference to shown in Fig. 1, a kind of cooking apparatus enamel liner, including cast iron courage body 10, outside the cast iron courage body 10
Surface sintering has enamel glaze layer 2, and the inner surface of cast iron courage body 10 is then coated with non-sticking lining 3, and wherein 3 material of non-sticking lining is preferred
For Teflon.By spraying non-sticking lining 3 in 10 inner surface of cast iron courage body, to ensure non-stick of the liner in culinary art.Pass through
The sintering enamel glaze layer 2 in the outer surface of cast iron courage body 10, to improve the appearance of the corrosion resistance of cast iron courage body 10 and liner.
It refers again to shown in Fig. 2, there is radially outer flange 1, the enamel glaze layer 2 at the courage mouth of the cast iron courage body 10
All extend to the flange 1 with non-sticking lining 3, the outer end face 11 of the flange 1 respectively with the top surface of flange 1 12 and bottom surface 13 it
Between there is turning, the corner that one of the junction of the enamel glaze layer 2 and the non-sticking lining 3 is located therein.
Enamel glaze layer 2 is ended to the corner of flange 1, and since outer end face 11 height of flange 1 itself is just smaller, because
The height smaller of this corner so that the irregularities at 2 end of enamel glaze layer are limited in the height region of a very little,
Defective region is limited in the region of a very little, reduces the generation of defect.
In addition, the irregularities of corner, are not easy to be easily noticed by the users, therefore appearance can't be influenced.Furthermore enamel glaze
Layer 2 ends at the corner of flange 1, and the bottom surface 13 of flange 1 is then covered by enamel glaze layer 2, and user is in hand rest flange 1, feel
Preferably.
And the junction of enamel glaze layer 2 and non-sticking lining 3 is located at the corner of flange 1, it is meant that do not lie in the top of flange 1
Face 12 is not closed by the lid of cooking apparatus cover, and steam etc. is difficult to contact and penetrates into enamel glaze layer 2 and non-sticking lining during culinary art
3 junction increases the corrosion resistance of liner, favorable rust preventing effect.
With continued reference to shown in Fig. 2, the turning between the outer end face 11 of flange 1 and the top surface 12 of flange 1 is the first turning 14,
The present embodiment preferably first turning 14 is as enamel glaze layer 2 and the link position of non-sticking lining 3.
Enamel glaze layer 2 is extended at first turning 14, make entire flange 1 outer end face 11 and bottom surface 13 by enamel
Glaze layer 2 covers, and in hand rest flange 1, Toe Transplantation for Segmental Finger will touch outer end face 11 to user, and feel is preferable, and the hand of enamel glaze layer 2
Feel thick and solid, good appearance, the experience of user is well.
During usual use, the outer end face 11 of flange 1 easily scrapes liner with kitchen wall or flume wall, this
Embodiment non-sticking lining 3 is extended at the first turning 14, and does not touch the outer end face 11 of flange 1, can avoid outer end face 11 by
It is scratched to non-sticking lining 3 when scraping, and enamel glaze layer 2 is since hardness is higher, anti-scratch ability is strong, it is difficult to be scratched
When damage.
Preferably, the height at the first turning 14 is 0.3-1.0mm, by controlling turning height in the range of 0.3-1.0,
So as to limit defect in the range of a very little, in addition the bonding pad area of enamel glaze layer 2 and non-sticking lining 3 is not under the size
Exist as too small and connect illusive problem.Wherein highly refer to：Under normal operating condition, liner courage mouth is upward and horizontal
During placement, the distance of vertical direction.
Wherein, the turning of 3 junction of enamel glaze layer 2 and non-sticking lining, i.e. the first turning 14 are chamfering or fillet.By
One turning 14, which is set as chamfering or fillet etc., has the structure of even surface, avoids the junction of enamel glaze layer 2 and non-sticking lining 3
Positioned at wedge angle position, so as to there are problems that easily being scratched.In addition enamel glaze layer 2 and non-sticking lining 3 all extend to chamfering or
On person's fillet, when making, the junction setting certain length both allowed overlaps area, the intensity that is combined both so as to improve and
Stereovision.Furthermore since the face of chamfering or fillet has a segment length distance, in the checkout procedure of making, it can pass through
Whether the enamel glaze layer 2 of observation sintering extends upper chamfering or fillet, so as to judge enamel glaze layer 2 be sintered whether it is qualified and,
Whether observation non-sticking lining 3 extends upper chamfering or fillet, so as to judge whether the spraying of non-sticking lining 3 is qualified.
It is sand mo(u)ld that iron casting, which uses, at present, and profile pattern is poor, thus on liner some have size will
The position asked need to be machined out.Liner is for cooking apparatus in the pots such as pressure cooker and rice cooker, by taking rice cooker as an example, with reference to Fig. 3 institutes
Showing, after the pot lid 20 of rice cooker lid closes, the top surface 12 with flange 1 is sealed cooperation by pot lid 20, therefore the top surface 12 of flange 1
Planarization is more demanding, and after the molding of cast iron courage body 10, the top surface 12 of flange 1 need to be machined out.The present embodiment is by first
Turning 14 is designed as chamfering or fillet, can directly be formed in the machining of top surface 12, in addition the present embodiment reduced size
Under the first turning 14 be also difficult to direct casting and forming.
Wherein, the thickness selected as 3-5mm of flange 1, using the size of the thicker flange 1, in casting and high temperature is burnt
When tying enamel glaze layer, the deflection of flange 1, reduction in the numbers of seconds can be reduced.
It refers again to shown in Fig. 2, non-sticking lining 3 covers the enamel glaze layer 2 at the first turning 14, for the ease of reason
Solution, the covering part of non-sticking lining 3, which is known as covering, does not glue section 31.Since enamel glaze layer 2 is is sintered, at end
Section planarization is poor (being similar to tooth form, tooth pitch and the irregular zigzag of tooth height), by covering not viscous section 31 by enamel
Glaze layer 2 covers, and the section for preventing planarization poor is exposed, so as to avoid penetrating into for water etc..On the other hand, it is collided in liner
Or when falling, the region for being most likely to occur collision is the corner of flange 1, although its very high quality of 2 hardness of enamel glaze layer
More crisp, scratch resistance is good but not impact resistance, and the impact resistance of non-sticking lining 3 is then better than enamel glaze layer 2, therefore is turned described
Non-sticking lining 3 is covered on the enamel glaze layer 2 at angle, and when can improve liner and falling or collide, the anti-of the corner is collapsed
Porcelain ability improves the service life of liner.
Wherein, preferably, the thickness of the not viscous section 31 of covering is less than the inner wall 101 that non-sticking lining 3 is covered in cast iron courage body 10
On thickness, the thickness value of the not viscous section 31 of covering may be selected 50-200 microns, 50-150 microns smaller than other positions；Enamel glaze layer
2 thickness being covered on the first turning 14 are less than the thickness being covered on the outer wall 102 of cast iron courage body 10, in order to make it easy to understand,
Enamel glaze layer 2, which is covered on the junction turning, is partly known as capped glaze interval 21, and being capped 21 thickness value of glaze interval can
50-200 microns of selection, it is 50-150 microns smaller than other positions.
For falling or during other accident collisions, the position being knocked is mostly corner, and enamel is due to not impact resistance
The characteristics of, by collision impact when easily collapses porcelain.Although the thickness of enamel glaze layer 2 the thick more is not susceptible to collapse porcelain, however by
It is smaller in the size of the present embodiment corner, therefore, it is difficult to spray blocked up thickness, since thickness can not possibly be very thick, and in cast iron
The thickness of courage is again heavier, under normal circumstances, falls when striking turning, the enamel layer of corner collapses the possibility of porcelain
It is larger, therefore premised on collapsing porcelain, experiment understands that the influence area for collapsing porcelain is related to its thickness, and smaller its of thickness collapses porcelain production
Raw power is smaller to the area of ambient influence, and the present embodiment uses the smaller capped glaze interval of thickness at the first turning 14
21, therefore when falling or other accidents collide, it can be reduced and collapse the influence area of porcelain, large area is effectively prevented and touch
Porcelain.In addition, its bond strength with cast iron courage body 10 of the smaller capped glaze interval 21 of thickness is less than the enamel glaze of other positions
Layer 2, therefore when colliding, capped glaze interval 21 can first collapse porcelain with negative function power, so as to weaken be transferred to it is other
The power of position enamel glaze layer 2 plays a protective role to the enamel glaze layer 2 of other positions.
Wherein, the thickness of the not viscous section 31 of covering is less than the thickness that non-sticking lining 3 is covered on 10 inner wall 101 of cast iron courage body,
It can avoid that there is apparent step trace with the junction of enamel glaze layer 2, realize more smooth transition.Preferably, connecting
Place, the not viscous section 31 of covering and capped glaze interval 21 seamlessly transit.
Under normal circumstances, enamel glaze layer 2 is divided for three-decker, is followed successively by the first reinforcing layer, the second reinforcing layer from inside to outside
With the face that highlights layer, per layer thickness between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.For above-mentioned
For capped glaze interval 21, the first bottom and/or the second bottom are can be only, it can not sintered surface layer；Or sintering has
First bottom, the second bottom and face layer is highlighted, but thickness ratio other positions are thin.
It for non-sticking lining 3, is coated under normal circumstances two layers, from inside to outside respectively bottom knead dough layer, every layer
Thickness is between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.Section 31 is not glued for above-mentioned covering
It says, the thickness ratio other positions of bottom knead dough layer are thin.
Embodiment two
Referring to Fig. 4, it is illustrated for a kind of cooking apparatus enamel liner embodiment two of the present invention.Itself and embodiment one
Difference is that the position that the enamel glaze layer 2 and the non-sticking lining 3 connect is different, specific as follows.
Turning between the outer end face 11 of flange 1 and the bottom surface 13 of flange 1 is the second turning 15,2 He of enamel glaze layer
The position that the non-sticking lining 3 connects is located at second turning 15.
The present embodiment makes since the position of enamel glaze layer 2 and the connection of the non-sticking lining 3 is located at second turning 15
The junction of enamel glaze layer 2 and non-sticking lining 3 downward, therefore even if culinary art when gas leakage condensed water is caused to be slided at flange 1
It falls, cast iron courage body 10 will not be penetrated into from junction, so as to obtain good corrosion resistance.
Preferably, the height at the second turning 15 is 0.3-1.0mm, by controlling turning height in the range of 0.3-1.0,
So as to limit defect in the range of a very little, in addition the bonding pad area of enamel glaze layer 2 and non-sticking lining 3 is not under the size
Exist as too small and connect illusive problem.Wherein highly refer to：Under normal operating condition, liner courage mouth is upward and horizontal
During placement, the distance of vertical direction.
It is sand mo(u)ld that iron casting, which uses, at present, and profile pattern is poor, thus on liner some have size will
The position asked need to be machined out.By taking rice cooker as an example, with reference to shown in Fig. 3 in embodiment one, after the lid conjunction of pot lid 20 of rice cooker, stew
Top surface 12 with flange 1 is sealed cooperation by lid 20, therefore the planarization of the top surface 12 of flange 1 is more demanding, in cast iron courage
After body 10 is molded, the top surface 12 of flange 1 need to be machined out.In addition, the diameter of the outer end face 11 of flange 1 also has one
Otherwise provisioning request is easy to pot lid 20 and interferes and cause pot lid 20 that can not cover conjunction, therefore machining also extends to the outer end of flange 1
Face 11.Fig. 4 is returned to, the second turning 15 is designed as chamfering or fillet by the present embodiment, the shape directly when outer end face 11 machines
Into in addition the second turning 15 under the present embodiment reduced size is also difficult to direct casting and forming.
With continued reference to shown in Fig. 4, non-sticking lining 3 covers the enamel glaze layer 2 at the second turning 15, for the ease of reason
Solution, the covering part of non-sticking lining 3, which is known as covering, does not glue section 31.Since enamel glaze layer 2 is is sintered, at end
Section planarization is poor (being similar to tooth form, tooth pitch and the irregular zigzag of tooth height), by covering not viscous section 31 by enamel
Glaze layer 2 covers, and the section for preventing planarization poor is exposed, so as to avoid penetrating into for water etc..On the other hand, it is collided in liner
Or when falling, the region for being most likely to occur collision is the corner of flange 1, although its very high quality of 2 hardness of enamel glaze layer
More crisp, scratch resistance is good but not impact resistance, and the impact resistance of non-sticking lining 3 is then better than enamel glaze layer 2, therefore is turned described
Non-sticking lining 3 is covered on the enamel glaze layer 2 at angle, and when can improve liner and falling or collide, the anti-of the corner is collapsed
Porcelain ability improves the service life of liner.
Wherein, preferably, the thickness of the not viscous section 31 of covering is covered in less than non-sticking lining 3 on 10 inner wall 101 of cast iron courage body
Thickness, the thickness value of the not viscous section 31 of covering may be selected 50-200 microns, 50-150 microns smaller than other positions；Enamel glaze layer 2
The thickness being covered on second turning 15 is less than the thickness being covered on 10 outer wall 102 of cast iron courage body, in order to make it easy to understand,
The part that enamel glaze layer 2 is covered in second turning 15 is known as capped glaze interval 21, and being capped 21 thickness value of glaze interval can
50-200 microns of selection, it is 50-150 microns smaller than other positions.
For falling or during other accident collisions, the position being knocked is mostly corner, and enamel is due to not impact resistance
The characteristics of, by collision impact when easily collapses porcelain, and the thickness of enamel glaze layer 2 the thick more is not susceptible to collapse porcelain, however, as this
The size of embodiment corner is smaller, and therefore, it is difficult to spray blocked up thickness, since thickness can not possibly be very thick, and the present embodiment is cast
The thickness of iron liner is again heavier, under normal circumstances, falls when striking the second turning 15, the enamel layer at the second turning 15
The possibility for collapsing porcelain is larger, therefore premised on collapsing porcelain, and experiment understands that the influence area for collapsing porcelain is related to its thickness,
Thickness it is smaller its collapse porcelain generation power it is smaller to the area of ambient influence, the present embodiment at the second turning 15 using thickness it is smaller
Capped glaze interval 21, therefore when falling or other accidents collide, it can be reduced and collapse the influence area of porcelain, effectively
Avoid large area blackmail.In addition, its bond strength with cast iron courage body 10 of the smaller capped glaze interval 21 of thickness is less than it
The enamel glaze layer 2 of its position, therefore when colliding, capped glaze interval 21 can first collapse porcelain with negative function power, thus
Weaken the power for being transferred to other positions enamel glaze layer 2, play a protective role to the enamel glaze layer 2 of other positions.
Wherein, the thickness of the not viscous section 31 of covering is less than the thickness that non-sticking lining 3 is covered on 10 inner wall 101 of cast iron courage body,
It can avoid that there is apparent step trace with the junction of enamel glaze layer 2, realize more smooth transition.Preferably, connecting
Place, the not viscous section 31 of covering and capped glaze interval 21 seamlessly transit.
Under normal circumstances, enamel glaze layer 2 is divided for three-decker, is followed successively by the first reinforcing layer, the second reinforcing layer from inside to outside
With the face that highlights layer, per layer thickness between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.For this implementation
For the capped glaze interval 21 of example, the first bottom and/or the second bottom are can be only, not sintered surface layer；Or first bottom,
Second bottom and the thickness ratio other positions for highlighting face layer are thin.
It for non-sticking lining 3, is coated under normal circumstances two layers, from inside to outside respectively bottom knead dough layer, every layer
Thickness is between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.Section 31 is not glued for the covering of the present embodiment
For, the thickness ratio other positions of bottom knead dough layer are thin.
Embodiment three
Referring to Fig. 5, it is illustrated for a kind of cooking apparatus enamel liner embodiment three of the present invention.Itself and above-described embodiment
Difference be that meltallizing has aluminium layer 4 between the cast iron courage body 10 and non-sticking lining 3.
After meltallizing aluminium layer 4, the bond strength of non-sticking lining 3 is increased, in addition, the heat transfer property of aluminium is better than iron, it can
Quickly the heat transfer of cast iron is gone out, so as to improve the efficiency of heating surface.
Wherein, the thickness of aluminium layer 4 is between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.
Example IV
Fig. 6-7 are please referred to, for a kind of cooking apparatus enamel liner example IV diagram of the present invention.Itself and above-mentioned implementation
Example difference be it is following some.
First, with reference to shown in Fig. 6, the side wall of cast iron courage body 10 is divided into side wall upper part 103 and lower sidewall 104, side wall
The wall thickness of top 103 and flange 1 is more than the wall thickness of lower sidewall 104.Preferably, the thickness of lower sidewall 104 is 2.5-
3.5mm preferably selects 3mm；The thickness of side wall upper part 103 is 3.2-4.2mm, preferably selects 3.7mm；The thickness of flange 1 is 3-
5mm, preferably 3.5-4.5mm, preferably select 4.0mm.
Liner has requirement due to need to be used cooperatively with cooking apparatus, to the planarization of 1 top surface 12 of flange, otherwise easily sealing
It is bad, however enamel liner is different from existing other liners, enamel glaze layer 2 need to could be with cast iron courage body 10 by high temperature sintering
With reference to, and the temperature of high temperature sintering is at 800 degree or so, and cast iron courage body 10 easily deforms upon after sintering, used in this programme compared with
Thick courage body sidewall top 103 and flange 1, and the design of relatively thin courage body sidewall lower part 104 is used, it is in sintering and cooled
The deflection of Cheng Zhong, courage body sidewall top 103 and flange 1 itself is small, and the deformation at courage body sidewall lower part 104 and courage bottom 105 generates
It is upward influence by courage body sidewall top 103 can then be weakened, the influence to flange 1 is small, thus when being sintered 1 top surface 12 of flange it is flat
Whole property can be guaranteed.
Second, referring again to shown in Fig. 7,105 portion of courage bottom forms the thermometric that thickness is thinned to courage body inner recess
Area 106.Preferably, temperature measuring area 106 is in the medium position at courage bottom 105, and preferred size is that 106 thickness of temperature measuring area is 1.5-
2.5mm preferably selects 2.0mm；105 thickness of courage bottom of non-temperature measuring area 106 is 2.5-3.5mm, preferably selects 3.0mm.
Cast iron obtains preferable heat storage capacity since its is thick and heavy, however liner thermometric at present, and detection is liner bottom surface
Temperature, and thicker courage bottom 105 leads to the temperature of food in the temperature measured and courage to have one due to the time difference of heat transfer
Fixed retardance, it is impossible to reflect the temperature of food in courage in time, and this programme is equipped with the temperature measuring area 106 that thickness is thinned, and passes through inspection
The temperature of the temperature measuring area 106 is surveyed, so as to improve the consistency with food temperature in courage, to provide preferably culinary art control.
In addition, when being sintered enamel glaze layer 2, courage bottom 105 can deform, by temperature measuring area 106 to courage body inner recess
Design, reduces the placement region area of liner, reduces the influence of sintering warpage.Also, temperature measuring area 106 is due to thinner thickness,
Its deflection deforms bigger compared to the other positions at courage bottom 105, and the concave design of temperature measuring area 106, deformation will not shadow
The planarization to the placed side 107 at courage bottom 105 is rung, is conducive to the placement of liner.
