Description
The utility model relates to pressure cooker, particularly a kind of pressure cooker of avoiding causing because of pot inner pressure is excessive blast that has safety device.
The utility model patent application a few days ago, open on the market, as to sell and use pressure cooker, usually adopting pressure cooker cover that pressure limiting valve and safety valve are set prevents that pot inner pressure is excessive and causes blast, but stop up when Stewed Dish easily causes pressure limiting valve and safety valve valve port in the pressure cooker pot of this structure, make it ineffective and blast, can't fundamentally solve explosion-proof problem; Both having made employing in the pot cover outer rim rectangle is set ejects mouth and solves the blast protection problem, but bring simultaneously not attractive in appearance, associative perception is poor, rectangle ejects mouthful punching stress and concentrates, cause bad mechanical strength, pot cover intensity to reduce, and easily cause sealing ring to rupture in the use, outside pot inner vapor transverse jet takes the dish out of the pot, equally easily cause defectives such as personal injury.
Goal of the invention of the present utility model is to overcome above-mentioned defective, and a kind of security performance height is provided, even pot inner pressure is excessive, and the not quick-fried safe pressure cooker that still can not blast.
Foregoing invention purpose of the present utility model realizes by following technical proposals:
A kind of not quick-fried safe pressure cooker, comprise: pot cover, pot body, several parts of sealing ring are formed, it is characterized in that pot recessed inwards pressure relief opening of body eversion edge setting, the corresponding chamber that ejects in the outer rim setting of pot cover and sealing ring contact position and pressure relief opening position to outer lug.
The recessed inwards pressure relief opening of described pot body eversion edge setting, the corresponding chamber that ejects in the outer rim setting of pot cover and sealing ring contact position and pressure relief opening position to outer lug, purpose is when the pressure cooker pot inner pressure reaches maximum sealing load value, sealing ring can crooked mobile heading into eject the chamber under the overvoltage vapor action, make to form between the sealing ring lip limit that covers pot body eversion edge and pressure relief opening and let out the vapour passage, steam discharges thus, the effect of pressure-relief explosion-proof when reaching pot interior overvoltage.
The purpose that is provided with that ejects the chamber is to provide sealing ring crooked space of moving under the overvoltage vapor action, limits sealing ring simultaneously and ejects in a large number and cause the accident.The sealing ring that wedge angle causes that produces in the manufacture process because of moving fracture, eject side, chamber and the best smooth connection of pot cover outer rim.
The purpose that is provided with of pressure relief opening is to provide overvoltage steam leakage mouth, and the position of pressure relief opening can be arranged on pot edge of body eversion edge, and its shape can adopt various ways, as: trapezoidal, rectangle or arc etc.; Also can be arranged on the eversion edge, as manhole, rectangular through holes, arcuation through hole etc.; Can also take separately that the outward flange of pot body eversion edge is further recessedly inwards with respect to usual pressure pot size in whole or in part, undertake the effect of pressure relief opening.For minimizing is therefore to the influence of pot body intensity to greatest extent, the pressure relief opening position is preferably disposed between the protruding tooth of pot body eversion edge.
The position on real limit is provided with and can adjusts definite according to the intensity of pressure cooker material, setting pressure and maximum sealing load value, the size of pressure cooker and the hardness of sealing ring etc. of pressure cooker in the pressure relief opening, to guarantee making sealing ring both can in pot, have good sealing effectiveness in the normal setting pressure scope, a pot normal function of use keep-ups pressure, the bending that when pot inner pressure reaches maximum sealing load value, guarantees sealing ring simultaneously move can with its generation pressure release passage, the purpose that reaches pressure-relief explosion-proof is the designing and calculating principle.Usually real back gauge pot mouth planar central point distance range preferably is controlled in the pressure relief opening: pot body radius adds wall thickness to pot body radius and adds between the protruding tooth height of eversion edge.
For the overvoltage steam that prevents to leak out directly blows downwards, cause electric heat source short circuit or other burning things which may cause a fire disaster from putting out, the position of pressure relief opening can be set in place between the protruding tooth of handle top pot body eversion edge, logical hollow structure in handle preferably is provided with and is, the hollow inner side plane is outward-dipping inclined-plane, make the steam that leaks out along this towards outside down discharge, avoid therefore taking place other accident.
In order to improve sealing ring seal degree and elasticity, sealing ring preferably adopts silicone rubber O-ring.
Working method of the present utility model is as follows: when using the not quick-fried safe pressure cooker of the basis have safety valve and pressure limiting valve, when generally pot inner pressure was excessive, pressure limiting valve or safety valve played the pressure release effect; When the safety valve of pressure cooker and pressure limiting valve because of stopping up or after other influence lost efficacy, sealing ring under the effect of overvoltage steam crooked move to form with pressure relief opening lets out the vapour passage, the steam discharge step-down reaches explosion-proof purpose.When using the not quick-fried safe pressure cooker of the basis do not have safety valve and pressure limiting valve, pot inner pressure is in normal setting range, and the sealing ring deflection is little, does not influence its sealing property, keeps normally using; When pot inner pressure reached maximum sealing load value, sealing ring is headed into ejected the chamber, formed with pressure relief opening and let out the vapour passage, and the steam discharge step-down reaches safe handling and explosion-proof purpose of design.
The pressure cooker of the utility model structure has good integrity, and its aesthetic appearance is strong, security performance height, long service life, advantage such as also can not blast when particularly pot inner pressure is excessive.
