【Embodiment】
The technical scheme of the embodiment of the present invention is explained and said with reference to the accompanying drawing of the embodiment of the present invention
It is bright, but following embodiments are only the preferred embodiments of the present invention, and it is not all.Based on the reality in embodiment
Example is applied, those skilled in the art obtain other embodiment on the premise of creative work is not made, all
Belong to protection scope of the present invention.
Embodiment one：
Reference picture 1, the cooking apparatus that the embodiment of the present invention one proposes, including pot and pot cover, the pot cover are buckled
Close in pot, inner bag 1 is placed with the pot, it will be appreciated by persons skilled in the art that in pot
Heater is additionally provided with to heat inner bag.Pot, pot cover and heater all refer to existing cooking pot
Tool, so the present embodiment is not described with reference to accompanying drawing.
Reference picture 1, the inner bag 1 that the present embodiment uses include side wall 11 and bottom wall 12.It is in arc that side wall 11 is overall
Shape evagination, the i.e. inner bag 1 are the spherical inner bag with evagination curved wall, and this kind of inner bag 1 is most obvious outer
Shape is characterized in that the diameter of side wall 11 is gradually decreased from middle part to upper and lower ends, so as to form approximate sphericity structure,
So referred to as spherical inner bag.The side wall 11 includes open section 14, thin neck section 13 and outwardly camber line
Section, the upper end of thin neck section 13 are connected with open section 14, and lower end is connected with arc upper end, the arc
Lower end is connected with bottom wall 12, and the thin neck section 13 includes the curved portions 132 to contract, curved portions and camber line
Section seamlessly transits, and the curved portions are on the extension arc of arc；Or the curved portions prolonging in arc
Stretch on the inside of arc；Or the curved portions are on the outside of the extension arc of arc.Thin neck section 13 can be understood as from side
To the lower end of open section 14 at side wall maximum latitude radius of circle R on wall.Because side wall is at maximum latitude radius of circle R
Up gradually taper up, extend out to form inner bag flange outside open section 14 just starts.Thin neck section 13
Curved portions 132 including thin neck 131 and to contract, thin neck can be one section or a bit,
It is position most thin in side wall, open section 14 makes inner bag stretch out to form opening.And curved portions 132 and arc
Shape section seamlessly transits, and can be on the extension arc of segmental arc, it can be understood as curved portions are with segmental arc one
On bar camber line；Curved portions can also be on the inside of the extension arc of arc or outside.
In the present embodiment, the maximum latitude radius of circle R of the side wall 11 and minimum latitude radius of circle r at thin neck section 13
Difference be 5-12mm, thus can improve Consumer's Experience.Specifically, when the difference is less than 5mm,
Think that difference is too small, refer to Fig. 3, the straight courage of inner bag 1a global approximations, the shape of inner bag can not be preferably
Promote rolling boiling, to the improvement unobvious of cooking quality.Now hot gas rolling path refers to Fig. 3
The middle direction of arrow, due to the approximate straight courage of side wall, it is impossible to hot gas effectively stop moving downward, hot gas
Moved upwards close to side wall of inner in inner bag, it is also possible to directly escaped from from inner bag oral area, the efficiency of heating surface becomes
It is low, to the improvement unobvious of cooking quality.When the difference is more than 12mm, it is believed that difference is too big,
Fig. 4 is referred to, inner bag 1b side wall evaginations are obvious, and the hot gas in inner bag is when rolling boiling, because side wall is curved
Qu Chengdu is larger, and side wall can effectively be stopped to hot gas, and now hot gas rolling path is referred in Fig. 4
The direction of arrow, hot gas rolling path can exceed inner bag center, therefore it is half-cooked make it that inner bag center is likely to occur
Situation, and due to inner bag excessively evagination, the difficulty of processing of inner bag becomes big, and easily exists and contain feeding
The blind area of material, it has not been convenient to which consumer uses.Therefore R and r difference is in 5-12mm, it is believed that difference is moderate,
The degree of sphericity of spherical inner bag is suitable, specifically, the difference can be 5mm, 6mm, 7mm, 8mm,
The numerical value such as 9mm, 10mm, 11mm, 12mm, culinary art effect now is more preferable, has more preferable user's body
Test.Fig. 2 is now referred to, in culinary art, the outer male structure of the side wall of inner bag 1 can promote the rolling of hot gas
Boiling, hot gas is upward along side wall, due to the appropriate stop of side wall, forms a certain degree of rolling, and then
Improve cooking quality.
It is understood that side wall latitude radius of circle refers to the radius that the circle that side wall of inner is formed is cut with horizontal cross-section,
Side wall maximum latitude radius of circle refers in the side wall of inner bag, in the radius that the circle that inner bag is formed is cut with horizontal cross-section
It is the horizontal cross-section of the maximum latitude circle to find the first section 200 in the radius R, Fig. 1 of maximum latitude circle.
Minimum latitude radius of circle r is similar at thin neck section 13, refers on the thin neck section 13 of inner bag, is cut with horizontal cross-section interior
The radius r of the latitude circle of minimum is found in the radius for the circle that courage is formed.In Fig. 1 the second section 300 for this most
The horizontal cross-section of small latitude circle.Or it is to be understood that maximum latitude radius of circle R refers to the widest part on side wall of inner,
I.e. at the first section 200, minimum latitude radius of circle r then refers on the thin neck section 13 of side wall of inner most at thin neck section 13
Narrow place, i.e., at the second section 300.In addition, when maximum latitude radius of circle R is 100-120mm, for example R is
100mm, 105mm, 110mm, 115mm, 120mm etc., the globality of inner bag can be relatively good.In addition,
Inner bag in the present embodiment is using the inner bag of the common volume of in the market as interior between premise, such as 3L-6L
Courage, such as 3L, 3.5L, 4L, 4.5L, 5L, 5.5L, 6L etc., naturally it is also possible to it is the inner bag of other volumes,
When being especially 4L or 5L inner bag here, the best results that above-mentioned number range obtains are applicable.
In the present embodiment, the distance between center of circle O that the thin neck section 13 is justified to side wall maximum latitude is L,
The distance provided with point P, OP is L i.e. on thin neck section 13.Because thin neck section 13 is one section of region, P points exist
Any position on thin neck section 13, O points are definite value so that OP distance may not be definite value.Tool
Body, when curved portions and segmental arc are on a camber line, and the arc be arc section, and carefully neck is
When a bit, when the center of circle of the arc section is simultaneously O, now OP value is exactly the radius of the arc section, this
When OP be definite value；In other circumstances, due to P be thin neck section 13 on a bit, L be OP away from
From, therefore L is the value of a change, it can be understood as L changes in a-b section, but L and R is carried out
When comparing, whether L=a, or during L=b, or during other values between a and b,
The absolute value for stating the maximum latitude radius of circle R and L of side wall 11 difference is less than 2 times of sidewall thickness.Further,
The absolute value of the difference of the R and L is less than sidewall thickness.Further, the R is equal with L.By
Differ in L and be set to definite value, when R is equal with L, L refers in particular to O to the distance of the thin lower end of neck 131.Cause
To be inner bag on horizontal profile, at side wall maximum latitude radius of circle be one, and using O as the center of circle, R is the circle of radius,
And when R and L difference is in a less scope so that side wall of inner also basic bit on sectional elevation
In using the round heart O of side wall maximum latitude as the center of circle, side wall maximum latitude radius of circle R is that inner bag is whole on the circle of radius
Shape seems that close to spherical the absolute value of especially R and L difference is less than the thickness of side wall, more
Close to spherical, or even when R is equal with L, side wall is exactly sphere at maximum latitude radius of circle.Now, can
Best promote rolling boiling, and outward appearance display effect is good.Because side wall is now rendered as spherical, hot gas
When rising, rise along spherical side wall, fallen after rise by the certain stop of side wall downwards, rolling boiling effect
Fruit is good, and cooking quality is improved.It is understood that the thickness of side wall embodies the heat storage capacity of inner bag,
Here R is associated with L difference with thickness, because when thickness is larger, inner bag heat storage capacity is stronger,
Allow R and L deviation can with larger, such as so that thickness is 2.5mm as an example, R and L difference it is absolute
Sidewall thickness of the value less than 2 times, i.e., less than 5mm, because this inner bag heat storage capacity is strong, have more heat
Gas is by inner bag bulk absorption, even if side wall of inner shape and spherical deviation are larger, the rolling boiling shadow to hot gas
Sound also can be less than normal；And thickness it is smaller when, inner bag heat storage capacity is weaker, it is allowed to R and L deviation just becomes big,
For example so that thickness is 1mm as an example, the absolute value of R and L difference is less than 2 times of sidewall thickness, i.e., should
Less than 2mm, because this inner bag heat storage capacity is weak, less hot gas is by inner bag bulk absorption, most of hot gas
Rolled in inner bag culinary art cavity, require inner bag sidewall shape high, it is necessary to as far as possible close to spherical, to promote
The rolling boiling of hot gas.
In the present embodiment, the arc of the side wall 11 include be connected with thin neck section 13 upper side wall 111,
The lower wall 112 and connection upper side wall 111 and the transition part 113 of lower wall 112 being connected with bottom wall 12, mistake
The heating uniformity of inner bag 1 can be improved by crossing the setting in portion 113, compared to existing common inner bag, in the present embodiment
The heating uniformity of courage 1 is more preferably.Its concrete structure and principle be referred to applicant previously applied it is entitled

In be no longer described in detail.
In the present embodiment, the thickness of the side wall is 0.6mm-5mm.When sidewall thickness is less than 0.6mm,
Inner bag intensity is weaker, influences product service life, when sidewall thickness is more than 5mm, waste of materials, and
Inner bag is too heavy, and consumer is made troubles.Sidewall thickness can select 0.9mm, 1.2mm, 1.5mm, 2mm,
2.5mm, 3mm, 4mm etc., other thickness in the range of this can also be selected.In addition, within the range
Sidewall thickness, heat accumulation best results, the heating to food materials in inner bag can either be realized, heat can be reduced again
Measure unnecessary waste.It is understood that the inner surface profile of the upper side wall 111 and lower wall 112 is bent
Line matches with outer surface profile curve.That is the thickness of side wall 11 is uniform.Transition part 113 is due to playing
For lower wall 112 to the effect of the transition of upper side wall 111, thickness is probably uniform, it is also possible to has certain change
Change.The present invention is mainly used as side wall when describing sidewall thickness using upper side wall 111 and the thickness of lower wall 112
11 thickness.
