Definitions

  • the present invention is related to the safety device of a pressure cooker, and more specifically, it refers to a safety pressure relief device of a family pressure cooker. Is a daily necessities.
  • the steam pressure cooker (commonly known as "pressure cooker") saves about 80% of energy and time than the pressureless cooker.
  • the average housewife is more or less resistant to the quick pot, the reason is that the quick pot has been exploded so far.
  • the fast cookers on the market at home and abroad even the Italian state-made ravioli cookers with high quality and safety, explosions often occur, causing injuries to human bodies.
  • the explosion of the above-mentioned fast cooker may be caused by the following reasons: 1.
  • the vent hole of the steam pressure if it is not cleaned properly or is not handled at all, or it is cooked with more residue, such as mung bean soup As a result, the exhaust valves (doors) are easily blocked, which causes the exhaust valves to fail to release pressure.
  • Improper combustion and heating causes the pressure velocity capacity generated in the pot to far exceed the amount of exhaust gas that the safety exhaust valve can withstand, and the abnormal pressure continues to increase to a considerable pressure.
  • the object of the present invention is to design a safety pressure relief device for a household quick cooker to protect the personal safety of users.
  • the full pressure relief device of the household quick cooker mainly includes a pot lid and a pot body.
  • the pot lid is provided with a steam control valve, an exhaust valve and a pressure relief device.
  • the pressure relief device is provided with a joint hole in the pot lid, and a pressure relief cover sheet is fixed on the joint hole.
  • the pressure relief cover sheet can be fixedly sealed from the bottom face of the pot lid to seal the joint hole. At this time, the pressure-relieving sealing sheet is kept in a sealed state.
  • the pressure relief sealing piece can be made into a movable elastic piston, one end of which is fixed to the pot lid, and the other end is the joint end of the pot curtain.
  • the piston is buried in the joint hole. When the pressure in the pot is normal, the piston is blocked. The joint hole, when the pressure in the pot is overpressure, the piston is pushed open by the air pressure item, and the air pressure is released from the joint hole.
  • the invention has the advantages of simple structure and safe use.
  • FIG. 1 is a schematic diagram of a preferred embodiment of the present invention.
  • FIG. 2 is a schematic diagram of the pressure relief of the preferred embodiment of the present invention.
  • a household pressure quick cooker safety pressure relief device of the present invention includes a pot lid (10) and a pot body (20), and a steam control is provided above the pot lid (10).
  • the valve (11) and an exhaust valve (12) are provided with a pressure relief device (14).
  • the pressure relief device (14) is provided with a joint hole (13) at a preset position of the pot lid (10), and The joint hole (13) is connected with a pressure relief seal (141).
  • the pressure relief seal (141) is a piece that is thinner from the periphery to the center, and the pressure relief portion is provided on the pressure relief seal ( 141), the pressure relief sealing piece (141) is placed on the bottom of the pot lid (10) and is arranged in the joint hole (13), and is exposed on the pot lid (10), and is also provided with a rivet (16) ) Add a pad ffi (15) to join, so as to stop being a pot When the inside is in a negative pressure state, the pressure relief device (14) thus falls into the pot. Of course, it can also be directly fixed in a spliced manner.
  • the pressure-relieving sealing sheet of the above-mentioned embodiment has no vent holes in principle, and even if there are vent holes, the vent holes are small.
  • the normal pressure is between 10 ⁇ : 15 pounds (4.54 ⁇ 6. 81 kg).
  • the pressure in the pot has gradually increased from the normal 10 ⁇ : 15 pounds, the traditional pressure cooker, The pressure can only be relieved by the rupture of the gel collar attached to the lid.
  • the above-mentioned safety pressure relief device designed by the present invention is set to a little after the pressure exceeds 15 pounds and before it exceeds 20 pounds, this safety pressure relief device will automatically rupture and achieve the effect of pressure relief. It is not necessary to allow the pressure to continue to increase to a great extent, and then the pressure is released by using the rupture of the rubber sleeve that is fully sealed between the lid and the body.
  • this safety pressure relief device (14) when the normal pressure exceeds a little bit, it will rupture to achieve the pressure relief effect, so the design can be made of appropriate materials, such as sheet copper or aluminum and Plastic materials, but in order to prevent toxicity and aesthetics, non-toxic plastic materials can be used.
  • this pressure relief device (14) in order that this pressure relief device (14) will not generate fragments when it is broken, so as not to hurt people, the surrounding material is designed to be thicker and the middle is thinner.
  • the pressure relief device (14) of the present invention will automatically rupture and vent.
  • the accumulated pressure can prevent the injuries caused by the explosion of the pressure cooker.
  • a rivet (142) is used to fix one end of the pressure relief seal (141) to the pot lid on the pressure relief seal (141) of the pressure relief device (14), thereby stopping The pressure-releasing seal (141) is completely detached from the pot lid and hurts the user.
  • the other end of the pressure-releasing seal (141) and the joint of the pot lid are a movable plug-type elastic piston (143).
  • the elastic piston (143) will be pushed and bounced out by the pressure item, so that the pressure relief sheet One end of (141) overcomes the force of engagement with the lid, and can be lifted off, thereby causing a perforated state in the pot, which can release the pressure of the plug and prevent accidents.
  • the pressure relief seal (141) in addition to being fixed by rivets (142), the pressure relief seal (141) can be fastened by, for example, a chain.
  • the traditional exhaust valve can also be used as a pop-out device. That is, the traditional exhaust valve only uses the exhaust hole to exhaust. When the exhaust hole is completely plugged, the exhaust effect is lost. When the pressure continues to increase to a great extent, the traditional pressure cooker uses the full sealing rubber sleeve of the pot lid and the pot body to rupture to release the pressure. Therefore, the present invention considers that a conventional exhaust valve can also be used instead of being completely killed. When the exhaust hole is completely blocked, the exhaust valve can also be popped out like the second implementation.
  • the safety device of the household pressure cooker of the present invention is installed on the pressure cooker.
  • the pressure relief seal is broken and the pressure in the pot is released, thereby avoiding the explosion injury of the pot people.
  • the safety device of the present invention is simple to set, safe to work, and good in safety performance.

Abstract

Dispositif détendeur de sécurité pour autocuiseur à usage ménager. Ce dispositif comporte une zone de détente pourvue d'un orifice sur le couvercle de l'autocuiseur. Un élément d'étanchéité de sécurité est prévu sur l'orifice. Cet élément peut être riveté sur le couvercle. L'une des extrémités de l'élément d'étanchéité de sécurité peut également être riveté sur le couvercle, et son autre extrémité peut faire corps avec le piston, de manière à obturer l'orifice. Lorsque la pression à l'intérieur de l'autocuiseur est normale, l'élément d'étanchéité de sécurité obture l'orifice, mais lorsque la pression à l'intérieur de l'autocuiseur est trop élevée, ledit élément d'étanchéité se rompt ou le piston est actionné et la pression est libérée par l'intermédiaire dudit orifice.
