The present invention relates to a pressure cooker, and more particularly to a pressure cooker used for stone cookers.

In general, stone cookers used in specialty restaurants are used to cook rice for one person in a short time. A stone cooked stone is usually made without a pot. Pots made of metals such as aluminum can be cooked in a short time by using a heater that can be heated intensive heat to the side edges and the bottom of the bottom of the pot before the pot. The structure that allows heat to be concentrated intensively on the side edges and bottom of the pot is formed in the upper crater of the burner that generates the flame. To do that. In addition, another method of cooking the contents of the pot in a short time is to seal the lid of the pot to the pot so that the internal pressure of the pot is increased during cooking, so that the contents can be quickly cooked. Typically, this type of pot is called a pressure cooker.

Conventional pressure rice cooker has no pot, it has a handle facing the main body and lid of the pot, and the protrusion of the main body is composed of several protrusions protruding radially outwardly, and the inner side of the lid has a protrusion corresponding to the protrusion of the main body radially inside When the lid is sealed to the body under the interposition of the packing, the protrusion of the lid is inserted below the protrusion of the body through the indentation between the protrusions of the body, and the lid is rotated to a certain range. The body and the lid can be sealed while being coupled to the lower side of the tank. This pressure cooker is heated so that the heat is concentrated only on the bottom portion of the cooker can be made of the contents.

Conventionally, such a conventional pressure cooker is a structure that is coupled to the main body of the pot by rotating the lid is conventionally equipped with a handle on the body and the lid. In addition, such a conventional pressure cooker is not composed of a pot cooker, and a heater having a cylindrical heat guide tube that allows heat to be intensively applied to the side periphery and the bottom of the pot cooker is not used. It is thought that this is because only the method of increasing the internal pressure of the pot is used among the methods of increasing the internal pressure of the pot and intensive heating of the side edge and the bottom of the pot for short time cooking.

In the present invention, in view of such a conventional point, the sealing combination of the pot and the lid is formed of the annular jaw formed in the middle of the lid and the combination of the outward protrusion and inward protrusion respectively formed before the pot and the lower periphery of the lid It is made by the coupling between the packing arranged at the lower side and the upper end of the pot, and the skirt part extending downward from the middle annular jaw where the packing is arranged at the lid is spaced from the upper edge of the pot and the packing at this part The through-hole formed when bending the bending piece inwardly to fix the outside air flows in the space between the skirt portion of the lid and the upper portion of the pot through this to prevent overheating of the packing, and the outward stone formed before the pot At the bottom of the jaw, a pin insertion hole is formed, and when it is ready to separate the pot and the lid, it is inserted into the pin insertion hole. Insert the pot into the pot fixing vessel formed in the upper flange of several pins so that the pins inserted into the upper flange of the pot fixing vessel are inserted into the pin insertion holes formed in the outward ridge before the pot. The handle is rotated so that the lid can be removed from the hot pot without having to hold the pot by hand.

To this end, in the present invention is composed of a pot of the pot is configured on the outer surface and the lid is covered on the upper portion of the pot, before the pot is formed with several radial outward projections between the several indents at equal intervals The lid has an annular jaw formed in the middle of the pot under the interposition of the packing at the upper end of the pot, and the lower periphery provides a pressure cooker in which a radial inward protrusion is formed so as to be coupled thereto in response to the outward protrusion of the pot. do. According to the present invention, a lower portion of the annular jaw extends the skirt portion which can be covered at regular intervals from the upper portion of the pot and the upper portion of the pot between the pot and at the bottom of the pot, and is placed on the upper portion of the pot before outward from the skirt portion. The lower jaw extends from the lower side to the lower side, and several narrow bent pieces are bent inwardly at equal intervals in the skirting direction so that the packing is fixed between the annular jaw and the bent pieces. When the bent piece is formed, a through hole is formed in the lower side of the bent piece so that the outside air flows through the space between the skirt portion of the lid and the upper portion of the pot to prevent overheating of the packing.

Referring to the present invention in more detail based on the accompanying drawings as follows.

1 and 2, the pot 10 is a form in which the inner layer 12 made of stone consists of an outer layer 14 made of metal such as aluminum. In the embodiment of the present invention, the pot 10 is illustrated as being composed of an inner layer 12 and an outer layer 14 of different materials, but the pot 10 may be made of a single material and may be made of a casting.

The pot 10 has a shape in which the pot 18 is formed on the outer surface at a predetermined distance from the upper end 16, and is covered with an upper portion of the pot 10 to seal the inside of the pot 20. ) Is a dome-shaped handle bar 22 is installed on the top and has a pressure relief valve 24 and the steam outlet 26 that is commonly used in pressure cookers.

In the pot 18 of the pot 10, several radial outward projections 30 are formed with several recesses 28 between them at equal intervals.

Lid 20 is formed in the form of a dome in the form of a dome in the middle is an annular jaw 32 to be placed on the upper end portion 16 of the pot 10 in the middle of the lower end of the annular jaw 32 A skirt portion 36, which can be covered at regular intervals from the pot top peripheral portion 34 between the bend 16 and the pot dish 18, is extended and again the upper portion of the pot dish 18 outwardly from the skirt portion 36. The lower annular projection (38) is placed on the lower periphery (40) extending downwards therefrom is formed radially inward projection (42) corresponding to the outward projection (30) of the pot (18).

In addition, at the lower side of the annular jaw 32 formed to be placed on the upper end portion 16 of the pot 10 in the middle of the lid 20, several bends are narrowly spaced at equal intervals in the circumferential direction from the skirt portion 36. The piece 44 is bent inwardly, and when the bent piece 44 is formed, the through hole 46 is formed below the bent piece 44, and the annular jaw 32 of the lid 20 and several The packing 48 is inserted between the bending pieces 44 so as to be supported.

When the lid 20 is hermetically coupled to the pot 10, the inward protrusion 42 of the lid 20 is formed through the indents 28 between the outward protrusions 30 formed at the pot front 18 of the pot 10. When entering the lower side of the outward protrusion 30 and rotates the lid 20 to a predetermined range using the handle bar 22 mounted on the upper portion, the inward protrusion 42 of the lid 20 is outward of the pot 18 The pot 10 and the lid 20 are moved while being coupled to the bottom surface side of the protrusion 30 and the packing 48 is pressed between the annular jaw 32 formed in the middle of the lid 20 and the upper end 16 of the pot. ) Can be sealed.

On the other hand, when the pin insertion hole 50 is formed on the bottom side of the pot pan 18 at the portion of the pot pan 18 where the outward protrusion 30 is formed, and then when cooking the pot 10 and the lid 20 to be separated. Several pins 52 inserted into the pin insertion holes 50 are inserted into the pot fixing vessel 56 formed on the upper flange 54 to the upper flange 54 of the pot fixing vessel 56. The inserted pin 52 is inserted into the pin insertion hole 50 formed in the pot 18 to fix the pot 10, and then the lid 20 using the handle bar 22 disposed on the top of the lid 20. Rotating) allows the lid 20 to be removed from the hot pot 10 without holding the pot 10 by hand.

The present invention put the contents to be cooked in the pot 10 and then cover the lid 20 and the inward protrusion 42 of the lid 20 between the outward protrusion 30 formed in the pot before the pot (18) Entering the lower side of these outward protrusions 30 through the recessed portion 28 of the inward protrusion of the lid 20 by rotating the lid 20 to a predetermined range using the handle bar 22 mounted on the upper portion thereof ( 42 is moved to the bottom side of the outward projection 30 of the pot 18, the packing 48 is pressed between the annular jaw 32 formed in the middle of the lid 20 and the upper end 16 of the pot While the pot 10 and the lid 20 is sealed.

Thus, the pot 10 with the lid 20 closed is cooked in the heater 66 having the heat guide cylinder 64 placed in a substantially cylindrical shape on the crater 62 formed on the upper portion of the burner 60. The pot 10 has a lower portion of the pot 18 before being inserted into the heat guide cylinder 64, and the lower side of the pot 18 is supported on the top of the heat guide cylinder 64 (see Fig. 2). The heat generated by the flame generated from the burner 60 of the heater 66 causes a high temperature to be applied to the packing 48 which substantially seals the lid 20 and the pot 10 while the contents of the pot 10 are being cooked. If so, the packing 48 may be degraded by heat, thereby degrading its function. However, in the present invention, the skirt portion 36 extending downward from the intermediate annular jaw 32 in which the packing 48 is disposed in the lid 20 is spaced from the pot top portion 34 at a constant distance. The skirt portion 36 of the lid 20 and the pot-shaped peripheral portion 34 of the lid 20 through the through-hole 46 formed when the bending piece 44 constituting to fix the packing 48 in the portion 36 to the inside. The outside air flows through the space between them to prevent overheating of the packing 48.

In this way, after cooking is completed, the pot 10 is lifted from the heater 66 by holding the handle bar 22 of the lid 20. The pot 10 is still hot and cannot be grasped with bare hands. In order to separate the lid 20 from the pot 10, a pot fixing vessel 58 as shown in FIGS. 4 and 5 is used. That is, after cooking is completed, grab the handle bar 22 of the lid 20 and lift the pot 10 from the heater 66 to move the pot 10 from the heater 66 and leave the pot 10 as it is the pot fixing container. Inserted in (58). At this time, the pin 52 inserted into the upper flange 54 of the pot container 56 is inserted into the pin insertion hole 50 formed on the bottom surface of the pot 18 to the pot fixing vessel 56 with the pot 10 ) So that it does not rotate. Thereafter, the inward protrusion 42 of the lid 20 is coupled to the outward protrusion 30 of the thinner 10 by rotating the lid 20 by using the handle bar 22 disposed on the top of the lid 20. By moving away from the state, the lid 20 can be removed from the hot pot 10 without holding the pot 10 by hand.

As described above, the present invention is the sealing of the pot and the lid is formed on the lower side of the annular jaw formed in the middle of the lid and the combination of the outward protrusion and the inward protrusion formed in the lower periphery of the pot and the lid, respectively, The skirt portion extending downward from the middle annular jaw where the packing is arranged in the lid is spaced apart from the pot circumference, and the bending piece is bent inward to fix the packing in the skirt portion. The through-holes formed during this process allow the outside air to flow in the space between the skirt of the lid and the upper edge of the pot to prevent overheating of the packing. After that, when you want to separate the pot and the lid, several pins are inserted into the pin insertion holes. Insert the pot into the container so that the pin inserted in the upper flange of the pot fixing container is inserted into the pin insertion hole formed in the outward protrusion before the pot, fix the pot, and then rotate the handle placed on the upper part of the lid to remove the pot from the hot pot by hand. Allow the lid to be removed without holding it.
