It is dynamic.
In the cooking process of the culinary art household electrical appliances such as electric cooker, electric pressure cooking saucepan, because moisture largely evaporates, can be inside steam valve
Substantial amounts of bubble is formed, so as to influence the mouthfeel of food.Enter steam valve when the steam in interior pot (or inner bag) carries soup
When, internal brokenly bubble structure, so as to promote steam to be separated with soup, can be kept away by modes such as rotation, vibrations by bubble breaking
Exempt from soup spill electric cooker in interior pot etc. and cook household electrical appliances.
As shown in Figure 1 and Figure 2, when electric cooker works, the steam of interior pot and big another typical material enter from steam inlet 101
Brokenly bubble steam valve, when interior pot steam pressure is larger, rolling element 1 can be pushed to the top of brokenly bubble chamber B1.Now, steam and bulla
Foam is entered by the circular gap (including lateral clearance J1 and vertical gap J2 of Fig. 3) between rolling element 1 and brokenly bubble chamber perisporium 2
In steam valve pocket B, finally outwards escaped via the steam (vapor) outlet 201 on steam valve cap 200.In the process through circular gap
In, there is a constant pressure drop in vapor pressure so that interior pan gas pressure is slightly higher compared to external pressure, that is, there is minute-pressure, is conducive to boiling
Rice.Meanwhile, macrofoam at least splits into numerous another typical materials through circular gap, and another typical material is larger in volume and pressure reduces
Steam valve pocket B in rupture, formed ponding flowed back from the bottom wall 102 of steam valve seat.And in digestion process, with firepower control
System and moisture are gradually decreased, and interior pot steam pressure is simultaneously unstable, and rolling element 1 also will be along the slide downward of roll tilt wall 21, in rolling
Kinetoplast 1 constantly extrudes macrofoam during up and down reciprocatingly rolling, and the ponding for being formed directly flows back along roll tilt wall 21.
Wherein, steam path is shown in each sectional view from steam inlet 101 to the curve of steam (vapor) outlet 201.
Referring to the force analysis of Fig. 4, the gravity of rolling element 1 is G, and gravity G straight down, press from both sides by the inclination of roll tilt wall 21
Angle is a, it is known that:Component F2=G*Sin (a) is pushed away under gravity, according to the stress balance along inclined plane, steam lifting force is derived
F1=F2+f, wherein f are the frictional force of inclined plane.When vapor action is S, roll tilt wall in the active area on rolling element 1
21 and rolling element 1 be respectively provided with smooth surface, with cause frictional force f it is negligible when, the steam of the bottom of brokenly bubble chamber B1 can be derived
Pressure difference P between air pressure and the vapor pressure at top should meet:
In other words, when the pressure difference P of only rolling element chamber pressure of both sides about 1 is sufficiently large, i.e. the interior pot of electric cooker
Vapor pressure exists under certain minute-pressure state relative to extraneous standard pressure, can push up rolling element 1, to keep preferable
Effect of breaking bubble.
In the specific embodiment shown in Fig. 3, rolling element 1 is the roller of cylinder, and the roller is along roll tilt wall 21
Lateral arrangement, a diameter of D of roller, axial length is L, then vapor action is in the active area S=D*L on rolling element 1;And
And
Brokenly bubble chamber B1 has rectangular cross section, and the width of the rectangular cross section is A1, and length is A2, then circular gap
Cross-sectional area S1=A1*A2-D*L.
Certainly it is only for example herein, i.e., brokenly bubble chamber is not limited to rectangle chamber, and rolling element 1 is also not necessarily limited to roller, at other
Under shape, the computing formula of active area S also can be equally obtained.
By above force analysis and calculating, the size of P depends on the gravity of rolling element 1, lifting surface area, inclines folder
The multiple parameters such as angle a.Meanwhile, the size of P is also limited by brokenly bubble chamber size size.In other words, by selecting control above-mentioned parameter,
Interior pot steam pressure is then adjustably controlled, to obtain the steam pressure of optimum boiling meal.
Similarly, to realize the miniaturization of brokenly bubble steam valve, the gravity G of the rolling element 1 meets:
Wherein, P is the pressure difference between the vapor pressure of bottom and the vapor pressure at top of brokenly bubble chamber B1, and value model
Enclose preferably 50~300pa;S be the vapor action in the active area on the rolling element 1, and span is preferably 90
~180mm2, a is the roll tilt wall 21 slanted angle with respect to the horizontal plane, and span is preferably 5 °~30 °.
So, pressure difference P (i.e. pot inner pressure), roller size, the isoparametric decision design scopes of angle of inclination a are being provided
When, required roller weight can be calculated, in order to selection, realize compact conformation, miniaturization and applicable brokenly bubble steam valve.
Drawn according to continuous experimental summary, when pressure difference P is preferably 50pa~300pa, can realize existing in pot
Micro-pressure, rolling element 1 can be moved up and realize effect of breaking bubble at this pressure again, while thin rice gruel easily backflow again.
In a particular embodiment, it is highly preferred that the scope of P is 100pa~200pa.If pressure difference P=100Pa, track inclines
Oblique a=18 ° of angle, S=120mm2, then can calculate gravity G ≈ 3.96g, the round numbers 4g of roller, by density formula ρ=
M/V=9.8N/kg, can calculate the density of roller, and then consider selection.
Additionally, brokenly bubble chamber is relatively small so that when circular gap is sufficiently small, internal pressure can be lifted, steam valve pocket B should be compared to
B1 is sufficiently large in brokenly bubble chamber, is conducive to maintaining the pressure drop of circular gap, and another typical material of being more convenient for all ruptures wherein.As an example,
In the illustrated embodiment, the volume ratio of steam valve pocket B and brokenly bubble chamber B1 is preferably not less than 5, and this is also not necessarily limited to certainly.
When vapor action is preferably 90~180 square millimeters in the active area S on rolling element 1, the gravity of rolling element 1
G is preferably 2~8 grams.Further, the cross-sectional area S1 of circular gap is preferably 50~100 square millimeters.For example,
If the diameter D=12mm of roller, axial length L=10mm, gravity G=4g, during a=18 ° of slanted angle, then P=F1/S ≈
100.9455pa.Now, according to above-mentioned rational parameter area, differential pressure requirements can be met, brokenly bubble steam valve can again realizes
Miniaturization, effectively destroys macrofoam and contributes to thin rice gruel to flow back.
To realize above-mentioned circular gap, referring to Fig. 3, can also be formed on the periphery wall of roller (its stereogram is referring to Fig. 6)
There is annulus fin 14, roof guide groove and bottom wall shown in Fig. 3 are respectively formed with the roof and bottom wall of brokenly bubble chamber B1 and are led

In, circular gap includes lateral clearance J1, is each formed between the outer peripheral face of roller and the top wall surface and wall surface of brokenly bubble chamber B1
Lateral clearance J1, so as to for the whole periphery wall of roller and the wall surface Full connected of brokenly bubble chamber B1, friction can be reduced
Area, reduces frictional force.
Be formed lateral clearance J1, naturally be contemplated that by the height of projection of annulus fin 14 be set greater than roof guide groove or
The depth of bottom wall guide groove, so as to form lateral clearance J1.But now only pass through annulus fin 14 between roller and brokenly bubble bottom of chamber wall
During contact, easily operation is unstable.In order to further increase stationarity when roller runs, as shown in figure 3, the both sides of bottom wall guide groove
Projected side wall protruding upward is respectively formed with, the periphery wall of roller is supported on two projected side walls, so as to lift roller
Stationarity during operation.After two projected side walls are set, the height of projection of annulus fin 14 further can be also made to be less than bottom
The depth of wall guide groove, that is, avoid annulus fin 14 from contacting the bottom surface of bottom wall guide groove, further reduces contact area.
