Embodiment 1
As shown in Figure 1, according to the steaming that the cooking pot lid of the present embodiment includes lid ontology and is arranged on lid ontology
Steam valve 100, steam valve 100 have for steam by exhaust passage 10, exhaust passage 10 is connected to hot junction inside cooking pot
The exhaust outlet 31 of cold end outside air inlet 51 and cooking pot a, wherein part for steam valve 100 or entire steam valve 100 are by fitting
It is molded in the heat conduction good material for conducting the heat in hot junction to cold end, middle cooking pot lid is all made of guarantor compared with the existing technology
The molding mode of adiabator, the cooking pot lid of the present embodiment by be arranged steam valve 100 part or all by be suitable for by
The heat in hot junction is conducted to the heat conduction good material molding of cold end, and heat conduction good material can be metal material such as aluminium alloy
Deng in this way under the premise of the thermal efficiency and heat-insulating property of inexcessive reduction cooking pot, passing through 100 heat conduction of steam valve, reduce
The temperature of exhaust passage 10, and then reduce makes bubble rupture in advance by the temperature of the bubble of exhaust passage 10, realizes anti-overflow
Function.Entire Anti-spill realizes not excessive increase structure and component, and ball brokenly bubble, turbine are broken compared with the existing technology
The modes such as bubble realize Anti-spill, have simple in structure, the easy advantage of cleaning up using the cooking pot lid of the present embodiment.
It should be noted that the hot junction in the present embodiment refers to steam valve 100 and the higher one end of cooking pot temperature of exhaust gas,
Cold end refers to steam valve 100 and the lower one end of external environment institute Contact Temperature.
Below to realizing that the principle of bubbles burst is specifically described by cooling：
The necessary condition that bubble maintains is to form dynamic balance with ambient enviroment, i.e., external and internal pressure difference and surface tension is flat
Weighing apparatus.When the environment temperature decreases, ps(equation 2) is decreased, so that external and internal pressure difference is more than surface tension, so that
Bubble is burst.
πR2(pv-psThe π R γ equations of)=2 1
Wherein, R is bubble radius, pvFor bubble inner pressure, psFor bubble external pressure.
PV=nRT equations 2
Due to by existing cooking pot majority by moulding (such as：PP materials) composition, therefore the present embodiment is good using heat conduction
Good material is (such as：The metal materials such as aluminium and aluminium alloy), to increase radiating efficiency, the bubbler temperature of steam valve intracavitary is reduced rapidly,
Realize better brokenly bubble and no-spill effect.(thermal coefficient of PP materials is 0.21-0.26W/mK, the thermal coefficient of fine aluminium
For 237W/mK).
According to three kinds of heat transfer types of thermal conduction study：Heat transfer (equation 3), thermal convection current (equation 4) and heat radiation (equation 5),
In the case that other parameters are constant, no matter which kind of heat transfer type, heat exchange area is bigger, and radiating efficiency is higher.
Q=Ah Δ T equations 4
Q=ε A σ T4Equation 5
Wherein, Q is the heat of unit time transfer, and k is thermal coefficient, and A is heat exchange area, and h is convection transfer rate, △
T is the temperature difference, and ε is radiance, and T is thermodynamic temperature.
It is specifically, how anti-overflow by heat conduction for the steam valve 100 of this implementation with further reference to Fig. 1, specific steam valve
100 include offering the valve deck 30 of exhaust outlet 31 and opening up the valve seat 50 of air inlet 51, and valve deck 30 is molded by heat conduction good material,
The material of specific valve deck 30 is changed to the metalwork based on aluminium and aluminium alloy by the moulding based on PP materials, to pass through valve
The quick conductive of lid 30 reduces the temperature of exhaust passage 10.Cooking pot work when, cooking pot discharge bubble from air inlet 51 into
Enter steam valve 100, is discharged from exhaust outlet 31 by exhaust passage 10, in this course, since valve deck 30 uses high heat transfer
Aluminium and aluminium alloy, the heat of bubble in steam valve 100 can be transferred in the external environment of cooking pot rapidly, reduce gas
The bulk temperature of bubble, and then the air pressure of bubble is changed, make bubble since external and internal pressure is unbalance to rupture, it is anti-to realize brokenly bubble
The purpose of spilling.
Preferably, the steam valve 100 of the present embodiment further includes the baffle 70 being arranged on valve deck 30 and valve seat 50, baffle 70
Be intervally arranged to extend 10 length of exhaust passage, so realize by extend bubble by exhaust passage 10 away from discrete time into
One step accelerates the rupture of bubble.
Concaveconvex structure and embossing are offered on the valve deck 30 of the present embodiment and baffle 70, and then changing for valve deck 30 can be increased
Hot area increases its heat exchange efficiency, further speeds up the rupture of bubble.
Embodiment 2
In the cooking pot lid of the present embodiment, difference lies in the valve decks 30 and valve seat in the present embodiment with embodiment 1
50 are molded by heat conduction good material, reduce the thermal efficiency of cooking pot in this way, but anti-overflow better.
Embodiment 3
It is distinguished with embodiment 1 by setting steam valve 100 to the molding of heat conduction good material, the cooking pot lid of this implementation
In body, cooking pot lid, which has, to be suitable for conducting the heat in hot junction to the heat-conducting piece of cold end, is realized hot junction by heat-conducting piece
Heat is conducted to cold end, and then reduces the temperature of the bubble by exhaust passage 10, realizes anti-overflow function.
Heat-conducting piece is specifically molded using the higher aluminium of thermal coefficient and aluminium alloy in this implementation, and heat-conducting piece is with chimeric, fastening
Or it the modes such as screws and is fixed on valve deck 30 or lid ontology in steam valve 100.There are tiny lines for the cold end or cold end of heat-conducting piece
Road or specific character and pattern increase the heat exchange area with mixed gas, then increase radiating efficiency.Cold end is appearance side,
It is formed with the pattern or shape of fragmentation.When work, for mixed vapour when by exhaust passage 10, heat is fast by heat-conducting piece
Speed is transferred in environment, is reduced the bulk temperature of bubble and is made bubbles burst, and the no-spill purpose of brokenly bubble is realized.
Embodiment 4
Difference lies in the heat-conducting pieces of the present embodiment to be molded in exhaust passage 10 with embodiment 3, and heat-conducting piece is to run through row
10 mode of gas channel is arranged, such as is close to the inner wall realization heat conduction of exhaust passage 10, and such heat-conducting effect is more preferable, and anti-overflow effect is more
It is good.
Embodiment 5
The utility model also provides a kind of cooking pot, including cooking pot lid, and cooking pot lid is above-mentioned cooking pot lid
Body has the advantages that anti-overflow effect is good to cooking pot, compared with the existing technology in other cooking apparatus with Anti-spill
Have the advantages that it is simple in structure, more specifically, cooking pot in the present embodiment is electric cooker.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
Among the protection domain that variation is created still in the utility model.
