Description
One, technical field:
The present invention relates to a kind of kitchen articles, especially relevant with pressure cooker.
Two, background technology:
Cross beam pressure cooker has the incomparable security of other pressure cooker, when pressure limiting valve is blocked and ineffective, high pressure gas in the pot is known from experience the pressure overcome the elasticity crossbeam, makes pot cover be lifted away from pot mouthful and discharges, from more this has solved the quick-fried pot problem of pressure cooker.But the pot cover of cross beam pressure cooker is to rely on the pressurization of elasticity crossbeam, realizes using locking very inconvenient by knob: at first be movable parts such as crossbeam, knob are more, and operation inconvenience; Next is to hold for the control of knob is difficult, and crossing pine can leak gas, and tension directly influences the service life of pressure cooker again.Though therefore the cross beam pressure cooker market certain because of safety has can't be popularized because of using inconvenience.
Patent CN99111766.2 discloses a cross beam pressure cooker that utilizes cam to realize pot cover locking.But because the every use of cross beam pressure cooker is once, crossbeam all must leave handle and lay again, add and increased movable part such as cam handle, so the operating process of folding lid and inconvenient.Patent CN00101314.9, disclosed pressure cooker and existing cross beam pressure cooker are basic identical, just replaced installing the handle of crossbeam with hook, and knob control are still adopted in the locking of pot cover, not from the inconvenient problem of use of this solution cross beam pressure cooker more.
Three, summary of the invention:
Task of the present invention provides a kind of cross beam pressure cooker of folding with convenience.
In order to solve above-mentioned task, solution of the present invention is: at first the pot cover of pressure cooker is made two parts up and down.It is the caping and the lid end, be equipped with on the end at lid and cover ear, the two ends of elasticity crossbeam penetrate to be covered ear and caping is pressed in firmly covers at the end, and caping and lid are sealing ring (the present invention is to call " O " shape sealing ring in the following text) sealing of " O " shape with cross beam pressure cooker cross section commonly used at the end; Next is that the end opening that covers the end is equipped with the sealing ring (the present invention is to call " Y " shape sealing ring in the following text) that the cross section is " Y " shape, again the pot mouth on the pot body is made to adapt to into the pot mouthful of " Y " shape sealing ring, and formerly on the pot body be used for installing the handle of elasticity crossbeam and the pressure limiting valve on the pot cover etc. and still remain unchanged.The cross beam pressure cooker of a Here it is folding with convenience of the present invention.In use,, rotate an angle gently, make and cover ear muff and get final product inside the handle as long as pot cover is placed on the pot mouthful.Because pot mouthful use " Y " shape sealing ring sealing.Therefore folding is very convenient.
Above-mentioned " O " shape sealing ring also can be replaced with planar seal ring, and " Y " shape sealing ring also can be replaced with " U " shape sealing ring, and the present invention no longer describes in detail, only is illustrated with " O " shape sealing ring and " Y " shape sealing ring.
When normally using at ordinary times, the elasticity crossbeam is pressed on caping and covers at the end, and wherein by the sealing of " O " shape sealing ring, the lid end and pot mouth are by the sealing of " Y " shape sealing ring, and the pot internal gas pressure is controlled by pressure limiting valve.When running into the blocked and ineffective abnormal conditions of pressure limiting valve, high pressure gas is known from experience the pressure that overcomes the elasticity crossbeam and caping is lifted away from cover at the end, makes " O " shape sealing ring ineffective and obtain release.Though cover the end at this moment because of covering ear muff inside handle, can not take place to lift, " Y " shape sealing ring will cover the end and the pot mouth is sealing, and the caping area can be bigger, is only second to a pot mouth, so do not have blocking problem, and its security is identical with common cross beam pressure cooker.Because the elastic force of elasticity crossbeam can guarantee that enough caping and lid, do not become flexible at the end when normal use or cleaning, therefore whole lid one integrated mass does not have unnecessary movable part, brings great convenience to use.
Adopt the present invention also can save the materials of cross beam pressure cooker in addition: the one, the caping area is less than the pot open area, so crossbeam can reduce the pressure of caping, and promptly crossbeam can reduce, and saves the materials of crossbeam; The 2nd, the pressure of caping is after once debugging successfully, but the use of long term, and therefore the knob of former locking usefulness can omit, as long as a nut gets final product with the wrench debugging; The 3rd, adjusting screw(rod) can be made the blast pipe of hollow double as pressure limiting valve and use; The 4th, on pot body and pot cover, do not put pot tooth and Gai Ya, not only safer, and can save or save the materials of handle.Therefore the cross beam pressure cooker of folding with convenience of the present invention has market potential.
