The present invention is assembled with bolts to form a space as much as the gap between the bottom of the rice cooker and the top surface of the cooking vessel to increase the heat collection effect of the rice cooker and the packing installed around the inner surface of the lid of the pressure cooker by expansion of steam pressure Pressure cooker safety switchgear with a collecting tank that can open the lid after safely discharging the compressed steam pressure by operating the switchgear installed on the upper surface of the lid to close the pot. It is about.

In the conventional pressure cooker, a handle is attached to both sides of the pressure cooker and a packing is installed to closely contact the inner surface of the lid and the upper circumference of the pressure cooker. The distortion caused the pressure cooker to always be ineffective, and both handles of the pressure cooker were connected to the heat collecting surface, so when the rice cooker was used alone, the handle was not felt.

And since there is no automatic safety valve in the pressure cooker, the operating lever is manually operated to release steam pressure, and when the lid is opened, the lid cannot be opened easily because the steam pressure is not completely discharged. Or burned.

The present invention solves this problem, the packing in the lid has airtightness, and the expansion pressure is installed in the key so that it can be completely discharged and opened by the operation of the switchgear, the structure and effect described by the accompanying drawings in detail Is as follows. The binding hole 3 'is matched with the binding hole 3' of the heat collecting container 4 and the binding hole 3 'with the binding part 6 of the handle 5 in the well-known pressure cooker 1' Tighten with a bolt (7) while forming an annular demand (9) around the inner surface of the lid (8) to fit the circular shape (11) to the outer surface of the annular packing (10) into the annular demand (9) The uneven portion 12 around the inner surface of the packing 10 in close contact with the upper circumferential surface of the pressure cooker 1 is formed to have an airtightness, and a plurality of wings 13 with lower circumferences in contact with the packing 10 of the pressure cooker 1. Protrudes but inserts a plurality of jaws 14 between the wings 13 on the inner surface of the lid (8) and rotates the two side handles (5 ') of the lid (8) to one side to the bottom of the lid (13) The inner jaw 14 is overlapped and the handle 5 and the handle 5 'are assembled to match.

Then, the opening and closing hole 15 is abutted on one side handle 5 'of the lid 8 so that the screw holes 17, 17' and the lid 8 of the inner frame 16 of the opening and closing hole 15 are opened. Drill the screw holes 17a and 17a 'consistently, and screw the male screw 19 of the valve body 18 into the screw holes 17 and 17a, and screw a screw cap into the screw holes 17' and 17a '. 20) by screwing both sides of the inner frame 16 assembled on the upper surface of the lid (8) vertically, but on both sides formed grooves (A) (B) (C) open to the top and into the grooves (B) The projections 22 extending to both sides of the shaped member 21 are inserted so that the flow plate 25 is provided on the lower surface of the valve 24 into the valve body 18 in the tip guide groove 23 of the shaped member 21. The upper surface of the valve 24 is supported while the lower surface of the double-sided shaft 26 is supported by the tip of the hanging piece 21 so that the shaft 26 is moved up and down along the groove A on both sides of the valve 24. Spring 30 is elastically installed on the upper rod 27 so that the cotton swab 27 is driven up and down into the distribution hole 29 drilled on one side of the cover 28 and into the groove (C) The shaft 26 'of the female operation piece 31 is inserted and one side of the shaft 26' extends through the groove C and the long hole D of the cover 28 to extend the shaft 26 '. Assembling the lever on the outer end, the operation of the lever by the projection 32 on the front of the operation piece 31 presses the back of the guide piece 21, the valve 24 provided between the guide grooves 23 is the guide piece 21 Since both sides of the shaft 26 are supported at the front end of the valve, the valve 24 which is blocking the valve body 18 is opened, and the rear surface of the protrusion 32 opens the heat-opening holes drilled at both ends of the operation section 33. 34, the insertion piece 35 flows about the axis 23 'of the operation piece 31 and moves back and forth between the operation pieces 33, so that the transverse 36 crossing the middle part of the operation piece 33 is a helix. The inner surface of the cap 20 is installed in the cylinder 37, and the operating rod 40 of the piston 39 inserted into the cylinder 37 by the guide hole 38 penetrating the upper portion of the center of the cylinder 37. The transverse 36 is blocked at the top of the cylinder 37 The insertion piece 42 is formed around the lower end of the clamping piece 43 inserted into the insertion groove 42 so that the piston 39 cannot be detached from the cylinder 37, and the rear surface of the operation period 33 is provided. The key 45 penetrating the inside of the handle 5 'and penetrating the key hole 44 drilled on one side of the lid 8 contacts the inner surface of the wing 13 of the pressure cooker 1 to open the lid 8. A plurality of steam outlets 46 are formed in front of the cover 28 that cannot be opened.

In this way, tighten the binding hole (3 ") with the bolt (7) in the binding hole (3) and the binding portion (6) of the handle (5) around the pressure cooker (1) and the handle (5) of the pressure cooker (1). Loosen the bolt (7) slightly and connect the binding hole (3 ') of the collecting container (4) to the binding hole (3 ") of the handle (5) to connect the collecting container (4) integrally with the pressure cooker (1). And tighten the bolt (7) while inserting the needle bar (unsigned) from the bottom of the handle (5) into the connection hole of the collector (4) to facilitate the installation of the collector (4). Combining the heat collecting tank (4) in order to obtain a protective heat to the pressure cooker (1) so that the heat rising around the bottom of the heat collecting tank (4) while preventing the heat dissipation to the outside between the pot (2) and the heat collecting tank (4) The heat of combustion is gradually discharged to the space portion of the binding portion 6, thereby saving the fuel and increasing the amount of combustion heat to the maximum value, and being utilized to boil the food in the pressure cooker 1 in a short time.

And the inner surface 11 of the packing 10 inserted into the annular demand 9 inside the lid 8 of the pressure cooker 1 boils the food in the pressure cooker 1 and is subjected to pressure when the steam pressure is expanded. (11) is strongly pushed into the annular demand (9) and at the same time the uneven portion 12 of the inner circumference of the packing 10 is pressured by the upper circumference of the pressure cooker (1) to have a close contact with the upper outer peripheral surface of the pressure cooker (1) The pressure cooker (1) having an airtightness was increased to boil the taste of sweet delicacy according to various foods.

As described above, when the food is boiled using the pressure cooker 1, the inner frame 16 integrally assembled to the lid 8 and the lever extending out of the cover 28 are rotated by the steam pressure in the pressure cooker 1. Since the piston 39 in the cylinder 37 is pushed upward, the operating rod 40 passes through the guide hole 38 of the spiral cap 20 and passes through the small hole 41 of the cover 28, thereby operating the piece ( The transverse section 36 of the operation section 33 connected to the insertion piece 35 of 31) is prevented from moving backward, and the front projection 32 of the operation piece 31 presses the rear surface of the hanging piece 21. Therefore, the guide grooves of the guide piece 21 have the shafts 26 at both sides of the protrusions 22 of the guide piece 21 of the guide piece 21 centering on the projection 22 inserted by the groove B. (23) The valve 24, which was raised from both sides and blocked the body of the bab, was opened and the compressed steam pressure in the pressure cooker 1 was ejected to discharge to the front outlet 46 of the cover 28. To There is no risk of manipulation.

At this time, when the steam pressure is completely discharged, the piston 39, which has been raised to the upper portion of the cylinder 37, falls off the clamping piece 43 installed in the lower surface insertion groove 42 of the cylinder 37 while the vapor pressure disappears. Since the operating rod 40 penetrated through the small hole 41 of the cover 28 is lowered to the lower side of the transverse 36, the transverse interval 36 of the operating section 33 on the operating piece 31 while the lever is rotated upward. ) Is moved rearward and at the same time penetrates the rear side and one side handle 5 'of the operating rod 33 and the keyhole 44 of the lid 8 and is fitted to the wing 13 surface of the pressure cooker 1. When the steam pressure to expand into the pressure cooker 1 is increased, the valve 24 close to the valve body 18 expands. The flow piece 25 is placed on the bottom surface of the valve 24 while pushing up the upper rod 27 that is elastically installed by the spring 30 by the steam pressure. Since the steam pressure is ejected and sprayed to the outside through the steam outlet 46 in the cover 28, it has a constant pressure in the pressure cooker 1 to boil food and to increase the thermal efficiency while saving fuel and in a safe state Since the key 45 is opened, the lid can be opened effortlessly without any danger, thereby providing convenience to housewives.
