The present invention relates to a pressure cooker lid safety opening and closing device to open and close the lid after completely removing the steam pressure generated in the pressure cooker.

There are many types of pressure cookers in the past, but these are the ones that manually discharge the steam pressure by using the operating lever, so this can only be used by housewives who have learned how to use them. Every time there was a feeling of fear.

The present invention completely eliminates this inconvenience by operating a lever between the pressure adjusting valve and the lid handle to completely remove the steam pressure in the pot, and at the same time the key connected to the operation guide is detached from the top of the pot body and the lid can be opened. Housewives and children can easily open and close in a flexible state without binge drinking.

This invention is described in detail by the accompanying drawings as follows.

A pot is formed around the top of a well-known pressure cooker (1) and the binding holes (3) are drilled on both sides of the pot (2) to screw the bolts from the top of the binding holes (3) to the bottom of the binding holes (3). Fastening the handle (4) in close contact with the small hole (6) drilled on the lower surface of the handle (4) to match the hole (5) drilled on the side of the heat collecting tank (7) connected from the hole (5) to the small hole (6) The low bar (8) is screw-fitted to assemble the pressure cooker (1) and the heat collecting container (7) integrally, and the plurality of wings (9) through the upper circumference of the cooker (2) of the pressure cooker (1) to cover the lid Fit a plurality of jaws (11) inwardly around the inner surface of the (10) staggered and twist the lid (10) to one side to fasten the lid (10) to the pressure cooker (1) is installed around the inner surface of the lid (10) The packing 12 can be brought into close contact with the upper circumference of the pressure cooker (1).

In addition, the opening portion 13 is in close contact with one side of the handle 4 'of the lid 10, and the key 14 extending from the opening portion 13 penetrates through the inner surface of the handle 4' so that the wing of the pressure cooker 1 is open. (9) Penetrated into the key hole 15 on one side of the lid 10 so as to fit on the surface and attaching the connecting nuts (17) and (17 ') to the inner frame (16) of the opening and closing (13) to the bottom surface. (17) (17 ') Drill the connecting holes (18) and (18') on the surface of the cap (10) to screw the male screw (19) of the tightening valve surface to the connecting nut (17) at the connecting hole (18). And the male screw 19 'of the cylinder 20 from the connecting hole 18' to the connecting nut 17 'to set up both sides of the inner frame 16 so that the cover 21 can be fitted thereto. The groove 22 is formed on one side of the inner frame 16, and the hole 24 is formed in the surface of the cover 21 to coincide with the groove 22, so that the cam 24 and the round plate 25 are formed into the hole 23. ) A mandrel is installed on the working shaft (27) so that the eccentric pin (26) of the Install the annular guide groove 28 into the groove 22 in the front of the plate 25 and insert the operating shaft 27 into the hole 23 to fit the lever 29 at the outer end of the operating shaft 27 The spring 33 is fitted into the extension rod 32 of the valve 31 by the flow hole 30 which fits and is drilled on the upper side of the cover 21, and the lower guide plate 34 of the valve 31 is inserted. Is inserted into the body diameter valve, and the cam 24 operates the valve 31 surface at the inner end of the operating shaft 27 of the lever 29 so that the valve 31 can be blocked or opened on the upper surface of the male screw 19. The eccentric pin 26 of the circular plate 25 has a key 14 connected to the rear end of the guide 35 when the guide 35 is pushed or pulled while being inserted into the guide groove 36 at the inner end of the guide 35. The support rod 39 of the piston 38 which is inserted into or detached from the keyhole 15 to the wing 9 surface and protrudes from the bending piece 37 to the upper portion of the guide 35 and flows into the cylinder 20. This bending piece (37) Connecting hole 42 of the fixing rod 41 to penetrate the inner frame 16 on the side of the cover 21 that can be distributed into the through hole 40 on the surface of the cover 21 to prevent the reciprocating movement back and forth The other side penetrates through the connection hole 42 is fastened with a nut on the bolt surface of the fixing rod 41.

Referring to the effect of the present invention configured in this way in detail as follows.

Inject the contents to boil the food into the pressure cooker (1) and lay down the lever (29). The valve (31) tightens the valve (31) face with the ball shot of the spring (33) elastically installed on the extension rod (32). (19) is in close contact with the guide plate 34 is inserted into the fastening valve and at the same time the eccentric pin 26 of the circular plate 25 pulls the guide groove 36 of the guide 35 so that the guide 35 The support rod 39 of the piston 38 in which the blade 9 of the key 14 connected to the rear end is unmovably supported, at which the bending piece 37 of the guide 35 is fitted into the cylinder 20. ) Can be put on the upper surface of the cover 21 as a connection hole 40, so when the steam pressure is increased when the pressure cooker 1 is heated to boil food, the piston 38 is operated by the steam pressure to support the rod. (39) penetrates through the connecting hole (40) of the cover (21) and the bending piece (37) of the guide (35) is not pushed to the rear to open the lid (10) of the pressure cooker (1). Therefore, it is possible to prevent burns on housewives due to the explosion according to the steam pressure of the pressure cooker 1 and to discharge the predetermined amount of steam pressure by a safety valve installed on the top of the lid 10 to open the lid 10. When the support rod 39 that protrudes into the connection hole 40 falls from the connection hole 40, the lever 29 is operated so that the cam 24 of the operating shaft 27 moves the surface of the valve 31 to the tightening valve. Since the eccentric pin 26 of the circular plate 25 pushes the guide 35 backward, the keyhole 15 of the lid 10 can be opened smoothly. Housewife or child can use it conveniently without any risk, and use the pressure cooker (1) and the heat collecting container (7) by inserting the connecting rod (8) into the hole of the handle (9) in the hole (8) of the heat collecting container (7). If you do not need the heat collector (7) and only loosen the connecting rod (8) can utilize only the pressure cooker (1) It will be with.
