Hereinafter, the present invention will be described with reference to the accompanying drawings. 1 and 2 are perspective views schematically showing the appearance of a putting pot 1 according to an embodiment of the present invention, and Fig. 7 is a sectional view of a putting pot 1.

A puffer pot (1) is a autoclave (100) for containing a material. The operation panel 500 is attached to the housing 120 that covers the autoclave 100 and contains the components and the front surface of the housing 120. Pressure cooker 100 A heating source 123 is attached to the outside of the pot wall 101 and the pot bottom surface 112 to heat the pressure cooker 100.

In the pot bottom 105, an agitating blade 113 for agitating the grains or the like introduced into the pressure cooker 100 is rotated to uniformly heat the grains and the like.

On the other hand, a plurality of safety valves (600), which will be described later in the "safety device ", are attached to the wall 101, and three holes (Hole 107,108,109) are drilled. The double hole 1 107 is connected to the solenoid valve 111 The hole 2 108 is connected to a relief valve (not shown), and the hole 3 is connected to a pressure sensor 505 to be described later on the operation panel 500 via respective pipelines (not shown).

The upper pot openings 102 and 103 of the pressure cooker 100 include a device for blocking the outflow of the vapor pressure 110 inside the pressure cooker 100. The structure of the upper pot openings 102 and 103 includes, One side of the casings 208 is attached, and a lid holder 201 is attached to the other side of the casings 208.

The lid holder 201 includes a center hole 207 in which the expansion valve 300 is rotatably attached to one surface and a vapor cover 204 that extends from the outer diameter of the center hole 207 and is bent downward, . The vapor cover 204 guides the discharge of the vapor pressure 110 downward to suppress the temperature rise of the heat insulating cover 321. The heat insulating cover 321 will be described later in the expansion valve 300.

As shown in FIGS. 2, 3 or 7, the pot opening portions 102 and 103 function as doors for introducing and extracting cereals and the like and at the same time are sealed with the pressure lid 200, A plurality of locking claws 102 are integrally formed at an end of the cooking cavity 101 extending from the cooking cavity 101. A locking protrusion 104 for inserting a cooking pot (not shown) at a predetermined interval below the locking claw 102 is integrally formed with the cooking cavity 101 And is in close contact with the pressure lid 200.

The expansion valve 300 and the pressure lid 200 pass through the central hole 207 of the lid holder 201 to be rotatable through a predetermined angle and are guided to the upper portion of the steam outlet 205 through the expansion valve leg 306 Respectively. When the pressure lid 200 is coupled with the pot openings 102 and 103, the pot openings 102 and 103 are aligned at a predetermined position by the guide of the center hole 207. The pressure lid 200 has a structure in which the pot openings 102 and 103 are closed to block the atmosphere and the pressure lid 200 is provided with a plurality of locking projections 202 extending from the outer diameter of the pressure lid 200. The plurality of locking projections 202 are uniformly formed with the outer diameter of the pressure lid 200 so that the steam pressure 110 inside the pressure cooker 100 is uniformly applied to the entire pressure lid 200.

A concave portion 103 between the latching brackets 102 which is sized to allow the latching protrusion 202 to pass therethrough in the same shape as the latching protrusion 202 does not contact the latching protrusion 202 Are formed in the openings 102 and 103 so that the latching protrusion 202 can pass through the latching recess 103 between the latching brackets 102. The locking protrusion 202 which has passed through the cramp recess 103 is seated on the pot packing (not shown), and when the expansion valve 300 serving also as a compression handle for sealing is rotated, the projection upper surface 202a is clamped So that the latching protrusion 202 is positioned directly below the latching bracket 102. The above and below positioning can be assumed by anyone in the industry, and a description thereof will be omitted.

9 according to one embodiment of the present invention is for clearly explaining the interrelationship between the latching protrusion 202 and the latching bracket 102. The latching upper surface 202a and the latching lower surface 102a, And is inclined in a form gradually increasing in thickness from the position (125) where it is abutted so as to be able to enter. The pressure lid 200 compresses the utensil packing (not shown) to a maximum extent to seal the utensil pack 200 (not shown) when the latching protrusion 202 is positioned immediately below the latching clamp 102 in accordance with the rotation of the compression handle 300, Structure.

4, 5, and 8 according to an embodiment of the present invention, the expansion valve 300 according to an embodiment of the present invention is configured such that the vapor pressure 110 in the pressure cooker 100 is shut off until it is expanded, The steam pressure 110 inside the steam generator 100 is instantaneously discharged.

 The most ideal pressure lid must be opened immediately rearward with respect to the vapor pressure 110 when opened, ie, in the conventional hinged shape, when the pressure cap shaft is hinged to any pot opening, The load is increased, which is not the best desirable. Also, since the hinge coupling of the pressure lid must use only one latching projection 202 on the hinge symmetrical side, the pressure lid must be made to some degree of weight to withstand the vapor pressure 110, Another emission load is added. In addition, the one locking projection 202 on the one side can be released only when a considerable force is applied at the time of puffing. In addition, the pressure lid which is exposed to the outside and performs the opening operation can damage the human body or other objects in the vicinity.

In the expansion valve 300 of the present invention, which improves the problems described above, the plug seal 304 is attached to the outer periphery of the pressure plug 302 and the pressure plug 302 that opens straight backward with respect to the vapor pressure 110 . A stopper piston (301) is attached to the center of the pressure stopper (302), and a half-circular groove (303) is machined with an outer diameter of the stopper piston (301)

The stopper piston (301) is adapted to move up and down within a cover cylinder (323) formed at the center of the expansion cover (320). Several through holes 317 are drilled in the wall of the cover cylinder 323 facing the half-groove 303 at the lowering top dead center at which the stopper piston 301 seals the steam outlet 205. The diameter of the through hole 317 corresponds to the maximum outer diameter of the half-circular groove 303 and has a size such that the iron ball 316 is inserted. The outer diameter of the iron ball 316 is the same as the outer diameter of the cylinder 323 so as to cover the iron ball 316 when the iron ball 316 passes through the through hole 317 and fits into the half- This position is the top dead center of the descent.

The elasticity of the elastic body 315 at the top dead center lowers the tightening cylinder 311 and prevents the iron ball 316 from being separated from the circular groove 303. Once the clamping cylinder 311 is lowered and interferes with the removal of the iron ball 316, the pressure cap 302 can not be raised even when a substantial vapor pressure 110 is applied to the pressure cap 302.

The inner diameter of the fastening cylinder 311 is not equal to the upper and lower diameters so that the upper inside diameter 314 adjacent to the bulging cover 320 is equal to the outside diameter of the covering cylinder 323 and the opposite lower inside diameter 313, The pressure cap 302 of the expansion valve 300 according to one embodiment of the present invention is configured such that the stopper 316 inserted in the half-groove 303 when the stopper piston 301 is lifted is separated from the half- (316) outer diameter and the inner diameter.

The upper inner diameter 314 and the lower inner diameter 313 of the fastening cylinder 311 are tapered at certain portions in the middle of the cylinder pores. (Not shown) in the form of a flying saucer is formed at a position intermediate the outer diameter of the tightening cylinder 311, and a packing 312 is attached to the outer periphery of the fastening blade (not shown).

The expansion cylinder 310 which forms the outer surface of the expansion valve 300 and accommodates the components of the expansion valve 300 therein is formed with a diaphragm 309 which is intercepted from the atmosphere and a lower portion of the diaphragm 309 The expansion valve legs 306 are integrally formed. The expansion valve legs 306 are arranged in a circular shape having a diameter equal to or greater than the expansion valve 300 and the expansion valve legs 306 are arranged in such a manner that the central axis of the steam exhaust port 205 and the central axis of the expansion valve 300 And may be attached or bolted to the upper surface of the pressure lid 200 so as to be aligned on the vertical line. The vapor pressure 110 passing through the vapor outlet 205 is discharged to the atmosphere at the interval between the expansion valve leg 306 and the expansion valve leg 306. [ Thus, the length of the expansion valve leg 306 is sufficiently long so that the vapor pressure 110 passes between the expansion valve legs 306 without bottleneck.

A diaphragm hole (not shown) is drilled in the center of the diaphragm 309 of the expansion cylinder 310, and an O-ring 308 is attached to a bore in the diaphragm hole (not shown).

The inside diameter of the diaphragm hole is a diameter of a degree to which the O-ring 308 is closely attached by the insertion of the O-ring 308 in such a degree that the lower outer diameter (not shown) of the coupling cylinder 311 passes.

Briefly describing the structure of the abnormal expansion valve 300 as an operation state,

The compression hole 322 is lowered to seal the steam outlet 205 with the compression stopper 302. At this time, the half-circular groove 303 of the stopper piston 301 and the through-hole 317 of the cover cylinder 323 are aligned, and the tightening cylinder 311 is lowered by the elasticity of the next elastic body 315, 303 to prevent the magnetic force of the pressure plug 302 from rising.

The solenoid valve 111 is opened and the vapor pressure 110 inside the autoclave 100 is supplied to the inside of the expansion cylinder 330 through the pipeline 107a And enters the space 326. Accordingly, the pressure in the A space 326 rises and the clamping cylinder 311 is raised against the elastic body 315 by the raised pressure. At the same time, the atmosphere of B space (not shown) is discharged to the atmosphere through the discharge port 319.

At the same time, as the clamping cylinder 311 rises, the iron ball 316 is released from the half-circular groove 303, and the pressure drop 302 is rapidly raised by the steam pressure 110, . On the other hand, a buffer material 305 is disposed between the pressure cap 302 and the diaphragm 309 to absorb the impact of the sharp rise.

5 according to one embodiment of the present invention, as another embodiment of the expansion valve 300,

The expansion valve leg 306 is extended to a length of about two in the conventional flushing device 800 composed of one pressure cooker and one opening of the pressure cooker. The elongated expansion valve legs 306 may be used as an inlet for grain or the like or as an outlet for expanded grain or the like.

  The position of the compression hole 322 of the expansion valve 300 also serves to visually confirm the expansion after the expansion of the expansion cylinder 310. The insulation cover 321 surrounding the expansion cylinder 310 has the expansion valve 300 as a compression handle It would be desirable to use a material that reduces heat transfer and provides elasticity to the user's hand when the pressure lid is closed and rotated during use.

6 according to an embodiment of the present invention, a pot inner pot 400 is a container for withdrawing or inputting grains or the like conveniently from inside the autoclave 100. The pot inner pot 400 has the same outer shape as the inside of the autoclave 100, 123 in order to facilitate the heat transfer of the pressure cooker 100. A rotating roots 114 for rotating the stirring wing 113 are installed at the center of the inner bottom of the pot (not shown), so that the handle 401 for taking out the pot inner pot 400 can flow, Respectively.

The rotating roots 114 are connected through the bottom of the endothelium and connected to the stirring blade 113 at one end of the inner bottom and to the coupler a 157 at the opposite end. The penetrating means and the like include a packing (not shown) to prevent leakage of water (porridge) filled in the pot inner pot 400.

The coupler a 157 is located in the concave portion 402 at the center of the bottom of the inner skin and the lower surface of the coupler a 157 does not project under the inner skin bottom surface 403. Therefore, even if the pot inner potion 400 is placed at any position outside the autoclave 100, it has a sense of stability.

2, 7, and 7 according to an embodiment of the present invention, a sieve 250 coupled on a bottom surface (not shown) of the lid so that the inner surface of the inner surface of the inner surface of the inner surface of the inner surface of the inner surface of the inner surface, The steam pressure 110 generated in the autoclave 100 during puffing is discharged to the steam outlet 205 through the pore and the expanded grains and the like are blocked by the sieve 250 so that the pressure inside the autoclave 100 400). The degree of puffing varies depending on the grain and the like, but for example, in the case of white rice, the puffiness of the rice grain is expanded by about 7 to 8 times. Therefore, it is preferable that the white rice be put into a volume of 1/8 of the volume of the pot endothelium (400) in a white rice quantity.

7, according to one embodiment of the present invention, a shaft 119 is rotatably attached to the bottom of the autoclave 100 at the center of the bottom of the autoclave 100, and in the autoclave 100 of the shaft 119, A coupler B (157b) is attached to one side, and a stirring gear (115) is attached to a lower side of the pot bottom surface (112). The shaft 119 is attached to the bottom 105 of the pot by means of a packing (not shown), so that the inside of the autoclave 100 and the atmosphere are shut off.

 Hereinafter, the power transmission relationship between the stirring vane 113 and the stirring source 125 can be sufficiently predicted by those skilled in the art, so that further explanation is omitted.

1, 7, 11, or 12 according to an embodiment of the present invention,

A communication between a user and an MCU (not shown) mounted on the PCB board 510 built in the housing 120 is made by a display device 501 and an input button 502 on the front surface of the main body housing 120 I am responsible. In the MCU, the temperature (515) of the puffer pot (1) according to the user's input. Pressure 514. Stirring speed (516). F / W (Firmware) capable of setting the time and the reservation 517 function are inputted. For example, coffee beans or barley (for barley tea) can be selected from a sub menu of the roast (512), or the like.

The roasting 512 function can be used at atmospheric pressure or constant pressure depending on the user's purpose and the compression hole 322 is lowered to seal the steam outlet 205 and set the pressure 514 together with the roasting 512 function . When the pressure set below is exceeded, the relief valve (not shown) discharges the set excess pressure to the atmosphere by the performance of the F / W, and the set pressure is maintained in the pressure cooker 100 and the roasting function is performed.

The heating source 123 and the lid heating source 206 according to the embodiment of the present invention are arranged such that all points of the vapor pressure 110 within the pressure cooker 100 It should be preheated above the boiling point of the water under expansion pressure. For example, if you set a puffing pressure of 5 atm, the temperature at which the water boils should be at least 150 ° C. If any of the above points is below 150 ° C, dew is formed at the point. The source of the dew is generated by vaporizing a part of water or the like in the inside of the pressure cooker 100, and the dew may obstruct the formation of the expansion pressure and cause insufficient expansion.

In particular, the pressure cooker 100 and the pressure cooker 200 have independent structures, and even if the respective heating sources 123 and 206 are appropriately designed, the pressure cooker 100 and the pressure cooker 200 are operated at the same temperature It is difficult to expect a rise. Accordingly, it is desirable that a plurality of temperature sensors (not shown) and a plurality of temperature control circuits (in the MCU) adjust the plurality of heating sources 123 and 206.

7, 10, 11 and 12 of the embodiment of the present invention,

      first; The password (P / W) is not required in the reservation, bake and roast (without pressure) function, but a password 521 can be requested 520 to expand cereals or steam roasted cereals under a certain pressure. The password 521 may be set by the user or not set. Specifically, when power is applied to the potting pot 1, the user does not request the password 521 for convenience in the selection of the bake and roast (without pressure) function 520, but the function of the puffer 511 and the stir (pressure 512) It is possible to use all the input buttons 502 after passing through the input button 521. The use or non-use of the pressure of the roasting function can be recognized by the MCU by means of a position sensor (not shown) of the compression hole 322 attached to the lower portion of the compression hole 322.

If the user does not set the password (521), all functions can be used as they are. In this case, the occurrence of a problem caused by the use of an unwanted person such as a child may be the responsibility of the user who has not set the password 521 in a certain area.

     In the setting and inputting of the password 521, the display device 501 displays a plurality of numbers "4" in the middle of Arabic numerals 0 to 9 for intuitive user convenience along with a password 521 request character 520, (501). If the user does not set the password 521, the arrangement of the number "4 " becomes the password 521. The password is set by operating a plurality of input buttons 502. In other words, intuitively, arrows toward the left and right of the input button 502 indicate the shift of the Arabic numerals, and arrows directed upward and downward of the input button 502 indicate increase or decrease of the Arabic numerals. The update of the password can be performed after confirming the current password 521.

       If the input numeral string is inconsistent with the set password, a character 522 corresponding to "inconsistent " is displayed, and a certain guiding character 523 is displayed when a numeral string of more than a certain number of times is inputted.

        second; A plurality of pressure sensing sensors 505 are mounted on the PCB board 510 so that they do not interfere with each other and each one of them constitutes a solenoid valve 111 and the other one of them functions as a relief valve I am responsible. Therefore, the two devices are not operated at the same time. However, when at least one abnormal pressure is detected in each of the devices, all functions of the puffing pot 1 are stopped and a schedule notification message 523 is displayed on the display device 501.

        When the cereal is put in after the preheating, the time of about 3 to 4 minutes elapses until the expansion pressure is reached, and thus the pressure display number of the display device 501 also increases sharply. As described above, the time lapse and pressure increase after the start of expansion are stored in the F / W of the MCU in correlation with each other. Therefore, when a correlation different from the above correlation occurs, it is expected that the sealing of the pressure plug 302, the leakage of the packing, the breakage of the safety valve 600, etc., A schedule notification message 523 is displayed.

           third; A plurality of safety valves 600 are attached to the wall 101. The safety valve 600 forms a space inside the screw thread 604 in the outer shape of the bolt for easy detachment and clogging only by a thickness enough to withstand only a part of the safety head 605. [ It is preferable that the safety valve 600 is made of a soft metal such as aluminum or the like. When a certain pressure or more acts on the safety valve 600, a V-cutting groove 603 is formed in the safety valve head 605 It is.

The safety valve 600 attached to the cell wall 101 is fastened with the nut 601 and can not be reused once it is damaged. In addition, when any one of the plurality of safety valves 600 is broken, the above-mentioned different correlation is generated, and the guide letter 523 is displayed on the display device 501, and all functions of the potting pot 1 are stopped.

     The safety valve 600 is to be used after being subjected to a number of tests in a public testing laboratory and the breakage pressure of the safety valve 600 is set at a considerable difference from the pressure of the pressure cooker 100 and is therefore only used in the putting pot 1 of the present invention .

      fourth; The solenoid valve 111 and the relief valve (not shown) are of a type B that is opened when there is no operating current, thereby preventing a problem of the constituent circuit or an abnormal pressure rise in the pressure cooker 100 during a power failure.

           The pressure cooker 100 according to the present invention is formed on all the surfaces to which the vapor pressure 110 is applied in a curved or curved shape favorable to the internal pressure. However, in the autoclave 100 having a more favorable pressure-resistant structure, it is preferable that the diameter of the pot openings 102 and 103 is reduced and the pot depth of the autoclave 101 is increased by the compensation of the volume.
