(pump 25)
The pump 25 is used to suck air out of the space enclosed by the extraction container 23 and the container lid 23a.

In this embodiment, the soup produced in the pressure cooker main body 11 is discharged into the extraction vessel 23 through the soup discharge pipe 21 under negative pressure by the pump 25 with the pressure cooker lid 13 removed from the pressure cooker main body 11 . transferred to

(Soup extraction method)
Next, a procedure (soup extraction method) for feeding the soup produced in the pressure cooker main body 11 into the extraction container 23 will be described (see FIGS. 2 to 4).
In FIGS. 2 to 4, ingredients put into the pressure cooker main body 11 etc. are indicated by white circles, and liquids put into the pressure cooker main body 11 etc. are indicated by x marks.
The soup extraction method includes, as will be described later, an ingredient introduction process, a cooking process, a decompression process, a lid removal process, and a discharge process.

The pressure cooker body 11 is placed on the trivet of the heating device 40 .
One end of a soup discharge pipe 21 is attached via a first valve 19 to the discharge port 11 a of the pressure cooker body 11 .
A strainer 17 is attached to the holding portion 11 b of the pressure cooker main body 11 .
The inner pot 15 is placed on the strainer 17 .
A container lid 23 a is attached to the extraction container 23 .
The other end of the soup discharge pipe 21 is attached to the first pipe attachment hole 23a1 of the container lid 23a.
A pipe of the pump 25 is attached to the second pipe attachment hole 23a2 of the container lid 23a.
As a result, the extraction container 23 is sealed with the container lid 23a, the soup discharge pipe 21, and the pipe that communicates the pump 25 with the extraction container.

With the first valve 19 closed, ingredients for the soup and liquid such as water are introduced into the inner pot 15 (ingredients introduction step, see FIG. 2).
A part of the liquid introduced into the inner pot 15 through the first hole 15a of the inner pot 15 and the second hole 17a of the strainer 17 flows between the pressure cooker main body 11 and the inner pot 15, or between the pressure cooker main body 11 and the pressure cooker main body 11. It leaks out between the strainers 17 .

A pressure cooker lid 13 is attached to the pressure cooker body 11, and the space between the pressure cooker body 11 and the pressure cooker lid 13 is sealed.
Heating by the heating device 40 is started, and cooking is started (cooking step, see FIG. 3).
Some of the ingredients that have become smaller due to cooking leak out between the pressure cooker body 11 and the inner pot 15 and between the pressure cooker body 11 and the strainer 17 through the first hole 15a and the second hole 17a. .

After the cooking is completed, the heating by the heating device 40 is stopped, and the pressure of the pressure cooker body 11 is lowered by cooling the pressure cooker body 11 (decompression step).
The decompression process may be in the form of waiting for the pressure to drop due to the temperature drop due to natural standing, or the pressure is reduced by exhausting via a pressure regulating valve (not shown) provided on the pressure cooker lid 13. may be in the form
However, in the case of natural standing, it takes time for the pressure to drop.
A decompression device 14 (a first decompression device 14a and a second decompression device 14b) is provided in the pressure cooker lid 13 in order to reduce the pressure of the pressure cooker body 11 at an early stage and perform the lid removing process early after the completion of cooking. is desirable.
Details of the decompression device 14 will be described later.

In the decompression process, after the pressure of the pressure cooker body 11 is lowered, the pressure cooker lid 13 is removed from the pressure cooker body 11 (lid removing process).
Further, the air in the space surrounded by the extraction container 23 and the container lid 23a is discharged by the pump 25 while the first valve 19 is opened by operating the pump 25 (discharging step, see FIG. 4).
When the space surrounded by the extraction container 23 and the container lid 23a becomes negative pressure, part of the liquid and ingredients in the pressure cooker main body 11 flows through the soup discharge pipe 21 into the extraction container 23.

(Effect of the invention)
Thus, even when the pressure cooker lid 13 of the pressure cooker is removed from the pressure cooker body 11, the soup produced in the pressure cooker body 11 can be transferred to an external container (extraction container 23).
The pump 25 is used to discharge air from the space surrounded by the extraction container 23 and the container cover 23a, but since the soup does not pass through the pump 25, the possibility that the inside of the pump 25 is contaminated with soup or the like is low.

In addition, since the soup is transferred by the negative pressure of the pump 25, the position of the outlet 11a and the position of the extraction container 23 can be set more freely than when the soup is transferred by gravity. However, the extraction container 23 may be provided at a position lower than the discharge port 11a, and the soup may be transferred from the pressure cooker main body 11 to the extraction container 23 by gravity without using the pump 25 (see FIG. 28). . Alternatively, the extraction container 23 may be provided at a position lower than the discharge port 11a, and a pump 25 may be used to transfer the soup from the pressure cooker main body 11 to the extraction container 23 by negative pressure and gravity (Fig. 29)

Since the pressure cooker lid 13 is detached from the pressure cooker main body 11, it is possible to carry out the straining work of crushing the ingredients into the inner pot 15 or the like by using a spatula or the like during transfer.
Further, clogging of ingredients such as pieces of meat in the first hole 15a and the second hole 17a can be visually confirmed and the clogging can be removed.

(Application example 1, lid holding portion 11c holding pressure cooker lid 13)
The pressure cooker lid 13 may be lifted by the user directly gripping the handle 13a of the pressure cooker lid 13. However, as shown in Application Example 1 described later, the pressure cooker lid 13 is attached to the pressure cooker main body 11. The pressure cooker lid 13 may be lifted by the lid holding portion 11c (see FIGS. 8 to 11 and FIGS. 19 to 27).

The lid holding portion 11c has a fixed arm 11c1, a movable arm 11c2, and a hook portion 11c3.
The fixed arm 11c1 is fixed to the side of the pressure cooker main body 11. As shown in FIG.
The fixed arm 11c1 has, for example, a substantially L shape extending laterally from the side portion of the pressure cooker main body 11 and further extending upward from the lateral tip.
The movable arm 11c2 is, for example, a rod-shaped member, and one end is attached to the upper end of the fixed arm 11c1 so as to be rotatable around a first axis LX1 parallel to one of the horizontal directions. A hook portion 11c3 is attached to the end portion.
The other end of the movable arm 11c2 is biased in a direction away from the pressure cooker lid 13 (upward).
The hooking portion 11c3 hooks the handle 13a of the pressure cooker lid 13 in a detachable manner, such as a hook.

Next, a procedure for holding the pressure cooker lid 13 using the lid holding portion 11c will be described.
From a state in which the hooking portion 11c3 does not hook the handle 13a of the pressure cooker lid 13 (see FIG. 8), the hooking portion 11c3 hooks the handle 13a of the pressure cooker lid 13 (see FIG. 9).
When the pressure cooker lid 13 is released from the pressure cooker main body 11, the other end of the movable arm 11c2 lifts the pressure cooker lid 13 upward due to the biasing force (see FIG. 10).

Since the pressure cooker lid 13 is heavy, the user has a burden when lifting it upward.
In addition, when the pressure cooker lid 13 is lifted, the high temperature steam inside leaks out from between the pressure cooker lid 13 and the pressure cooker main body 11, so that the user who lifts the pressure cooker lid 13 may be exposed to the high temperature steam. was there.
In Application Example 1, the lid holding portion 11c lifts the pressure cooker lid 13 upward. Therefore, it is possible to reduce the burden of lifting the pressure cooker lid 13 on the user. In addition, the user can lift the pressure cooker lid 13 upward using the lid holding portion 11c at a position where steam does not hit easily.

The hooking portion 11c3 of the lid holding portion 11c hooks the pressure cooker lid 13 in a detachable state. Therefore, the pressure cooker lid 13 can be separated from the pressure cooker main body 11 for cleaning.

In addition, by moving the other end of the movable arm 11c2 further upward, the pressure cooker lid 13 is lifted further upward. As a result, the pressure cooker lid 13 is tilted or upright (see FIG. 11).

The movable arm 11c2 may be configured to be capable of rotating not only around the first axis LX1 parallel to one horizontal direction, but also around two axes.
By rotationally moving about two axes, the pressure cooker lid 13 can be moved in three-dimensional space. Therefore, the lid holding portion 11c can hold the pressure cooker lid 13 in a positional relationship in which the pressure cooker main body 11 and the pressure cooker lid 13 do not overlap when viewed from above (see FIGS. 19 to 21).

19 to 21, the movable arm 11c2 is held by the fixed arm 11c1 in a state in which it can rotate about the first axis LX1 and rotate about the second axis LX2 parallel to the vertical direction. Give an example.
19 shows the state before the lid holding part 11c holds the pressure cooker lid 13, FIG. 20 shows the state where the lid holding part 11c lifts the pressure cooker lid 13 upward, and FIG. A portion 11c shows a state in which the pressure cooker lid 13 is moved to a position displaced from the pressure cooker main body 11 when viewed from above.

Alternatively, instead of the movable arm 11c2 rotating around the first axis LX1, the hooking portion 11c3 may be held by the movable arm 11c2 in a vertically movable state (Figs. 27).
Moreover, the hooking portion 11c3 is not limited to a form having a hook shape, and may have a form having another shape, for example, a form having a fork shape.
In addition, the hooking portion 11c3 is not only configured to hook the handle 13a of the pressure cooker lid 13 in a detachable manner, but also other members that protrude upward from the upper surface of the pressure cooker lid 13 (upper projecting portion 13b). ) may be detachably hooked.

22 to 27, the movable arm 11c2 is held by the fixed arm 11c1 in a rotatable state about the second axis LX2, and the hooking portion 11c3 is movable in the vertical direction and biased upward. An example is shown in which the pressure cooker lid 13 is held by the movable arm 11c2 and the hooking portion 11c3 hooks the upper protruding portion 13b of the pressure cooker lid 13. FIG.

22 and 23 show the state before the lid holding part 11c holds the pressure cooker lid 13, and FIGS. 26 and 27 show a state in which the lid holding portion 11c has moved the pressure cooker lid 13 to a position where it does not overlap with the pressure cooker main body 11 when viewed from above.

Moreover, the method for holding the pressure cooker lid 13 by the lid holding portion 11c is not limited to latching, and other methods such as holding by pinching and holding by adsorption may be used.

The pressure cooker lid 13 can be moved in a three-dimensional space by rotational movement around one axis and parallel movement in a direction (first direction) parallel to the axis. Therefore, the lid holding portion 11c can hold the pressure cooker lid 13 in a positional relationship in which the pressure cooker main body 11 and the pressure cooker lid 13 do not overlap when viewed from above.
In this embodiment, the first direction is the vertical direction, but it may be another direction.

Note that the lid holding portion 11c may be configured such that one end of the movable arm 11c2 is rotatably attached to the side portion of the pressure cooker body 11 without providing the fixed arm 11c1.

(Application example 2, inner pot 15 and strainer 17)
In the present embodiment, a mode in which both the inner pot 15 and the strainer 17 are provided has been described, but a mode in which only the strainer 17 is provided as shown in FIG. 6 and a mode in which only the inner pot 15 is provided as shown in FIG. may be When only the inner pot 15 is provided, the holding portion 11 b holds the inner pot 15 .
Alternatively, the ingredients may be put directly into the pressure cooker main body 11 without providing the inner pot 15 and the strainer 17 .

(Application example 3, dual structure of strainer 17)
Alternatively, only the strainer 17 may be used without using the inner pot 15, and the strainer 17 may be composed of a thin and light upper strainer 171 with a fine mesh and a thick and heavy lower strainer 172 with a coarse mesh. (See FIG. 15).
The upper strainer 171 is held by the pressure cooker main body 11 or the lower strainer 172 in a state close to the lower strainer 172 .
In this case, the lower strainer 172 is used to keep the upper strainer 171 strong.
The upper strainer 171 may be deformed by applying force from above when the ingredients are crushed using a spatula or the like. In application example 3, the upper strainer 171 is arranged above the lower strainer 172 . Therefore, even if force is applied from above, the upper strainer 171 is less likely to deform.

(Application example 4, first decompression device 14a)
Next, the first decompression device 14a provided on the pressure cooker lid 13 will be described (see FIGS. 12 to 15).
The first decompression device 14a lowers the temperature inside the pressure cooker body 11 by volumetric expansion during evacuation.

The first decompression device 14a includes a first receiving pan 14a1, a first O-ring 14a2, a first fitting 14a3, a first mounting hole 14a4, a first exhaust hole 14a5, an exhaust pipe 14a6, a second valve 14a7, and a first discharge dispersing unit. 14a8.

The first receiving plate portion 14 a 1 is attached to the inner wall of the pressure cooker lid 13 .
The first receiving plate portion 14a1 is sandwiched between a lower protruding portion 13c protruding downward from the inner wall of the pressure cooker lid 13 in a ring shape and a first O-ring 14a2. It is fixed to the inner wall of the pressure cooker lid 13 .
The first attachment tool 14a3 passes through a first attachment hole 14a4 provided in the first receiving plate portion 14a1.
By attaching the first receiving plate portion 14a1 to the inner wall of the pressure cooker lid 13, the first receiving plate portion 14a1 and the pressure cooker lid 13 form a first space sp1.
The first space sp1 is sealed by the pressure cooker lid 13, the lower projecting portion 13c, the first receiving plate portion 14a1, the first O-ring 14a2, and the exhaust pipe 14a6.

A first exhaust hole 14a5 is provided in the first receiving pan portion 14a1, and a second exhaust hole 13d is provided in a portion of the pressure cooker lid 13 that forms the first space sp1.
Therefore, in the application example 4 using the first decompression device 14a, the pressure cooker lid 13 needs the lower projecting portion 13c and the second exhaust hole 13d as compared with the configuration without the first decompression device 14a.
However, in Application Example 4, since the steam inside the pressure cooker main body 11 can be discharged using the first decompression device 14a, the pressure cooker lid 13 does not need to be provided with a pressure regulating valve.
The hole diameter of the first exhaust hole 14a5 (the sum of the hole diameters of the plurality of holes if there are more than one) is smaller than the hole diameters of the second exhaust hole 13d and the exhaust pipe 14a6.

One end of the exhaust pipe 14a6 is inserted into the second exhaust hole 13d.
One end of the exhaust pipe 14a6 is arranged in the first space sp1 so that the one end of the exhaust pipe 14a6 is positioned near the bottom surface of the first receiving pan 14a1.
As a result, the liquid accumulated in the first receiving tray portion 14a1 can also be discharged efficiently.
A second valve 14a7 is provided in the exhaust pipe 14a6.
The second valve 14a7 is opened during the decompression process and closed during the other processes.
The other end of the exhaust pipe 14a6 is attached with a first exhaust dispersing portion 14a8 capable of exhausting in three directions.
The first discharge dispersing part 14a8 has a substantially hollow cylindrical shape, the upper part of which communicates with the exhaust pipe 14a6, the side part of which is provided with three or more discharge ports at regular intervals, and the lower part of which is closed.
It is desirable that the other end of the soup discharge pipe 21 is also provided with a second discharge dispersion portion 21a similar to the first discharge dispersion portion 14a8 of the exhaust pipe 14a6.

Until the depressurization process is completed, the exhaust pipe 14a6 is attached to the extraction vessel 23 through the first pipe attachment hole 23a1, and the first discharge distribution part 14a8 is arranged at the bottom of the extraction vessel 23 (Fig. 13). , see FIG. 14).
Also, the soup discharge pipe 21 is removed from the extraction container 23 until the pressure reduction process is completed.
The pipe of the pump 25 may not be attached to the extraction vessel 23 until the decompression process is completed.

The exhaust pipe 14a6 is removed from the extraction container 23 after the lid removing step after the completion of the decompression step (see FIG. 15). Further, the exhaust pipe 14a6 may be removed from the pressure cooker lid 13 after the lid removing step.
After the lid removing step, the soup discharge pipe 21 is attached to the extraction container 23 via the first pipe attachment hole 23a1.
After the lid removing step, the pipe of the pump 25 is attached to the extraction container 23 via the second pipe attachment hole 23a2.

However, before and after the lid removing process, both the exhaust pipe 14a6 and the soup discharge pipe 21 may be attached to the extraction container 23 without removing or attaching one of them.

In the cooking process, the first valve 19 and the second valve 14a7 are closed (see FIG. 13).
During the pressure reduction process, the second valve 14a7 is opened (see FIG. 14).
The steam and air inside the pressure cooker main body 11 pass through the first exhaust hole 14a5 and the exhaust pipe 14a6 and are discharged from the first discharge dispersion part 14a8.

The first discharge distribution part 14a8 has a structure that allows discharge in three or more directions. For this reason, compared to a configuration in which the first discharge dispersing portion 14a8 is not provided, the other end of the exhaust pipe 14a6 (where the first discharge dispersing portion 14a8 is located) can be exhausted without moving significantly.

Steam passes through the first exhaust hole 14a5 with a small hole diameter, and in the first space sp1, the temperature of the steam drops due to volume expansion, and the temperature around the first space sp1 drops.
As a result, the temperature of the pressure cooker main body 11 can be quickly lowered more easily than in the case where the internal steam is discharged using a normal pressure regulating valve.
In addition, due to the muffler effect due to the steam being discharged through the first space sp1, it is possible to reduce the sound of the steam being discharged, compared to a form in which internal steam is discharged using a normal pressure regulating valve. I can.

After the decompression process is completed, the pressure cooker lid 13 is removed from the pressure cooker main body 11 (lid removing process).
In addition, the pump 25 is actuated and the air in the space surrounded by the extraction container 23 and the container lid 23a is discharged by the pump 25 with the first valve 19 opened (discharging step, see FIG. 15).
When the space surrounded by the extraction container 23 and the container lid 23a becomes negative pressure, part of the liquid and ingredients in the pressure cooker main body 11 flows through the soup discharge pipe 21 into the extraction container 23.

(Application example 5, second decompression device 14b)
Next, the second decompression device 14b provided on the pressure cooker lid 13 will be described (see FIGS. 16 to 18).
The second decompression device 14b lowers the temperature inside the pressure cooker body 11 by water cooling.
The second decompression device 14b has a second receiving pan 14b1, a second O-ring 14b2, a second attachment 14b3, a second attachment hole 14b4, a water inlet pipe 14b5, a cooling water supply device 14b6, and a drain pipe 14b7.

The second receiving plate portion 14b1 is attached to the inner wall of the pressure cooker lid 13. As shown in FIG.
The second receiving plate portion 14b1 is sandwiched between a lower projecting portion 13c projecting downward from the inner wall of the pressure cooker lid 13 in a ring shape and a second O-ring 14b2, and a second fitting 14b3 such as a screw is used to hold the pressure. It is fixed to the inner wall of the pot lid 13 .
The second attachment 14b3 passes through a second attachment hole 14b4 provided in the second receiving plate portion 14b1.
The second O-ring 14b2 has the same structure as the first O-ring 14a2, the second mounting fixture 14b3 has the same structure as the first mounting fixture 14a3, and the second mounting hole 14b4 has the same structure as the first mounting hole 14a4. has the same structure as
By attaching the second receiving plate portion 14b1 to the inner wall of the pressure cooker lid 13, the second receiving plate portion 14b1 and the pressure cooker lid 13 form a second space sp2.
The second space sp2 is sealed with the pressure cooker lid 13, the lower projecting portion 13c, the second receiving plate portion 14b1, the second O-ring 14b2, the water inlet pipe 14b5, and the drain pipe 14b7.

The second receiving plate portion 14b1 is not provided with an exhaust hole such as the first exhaust hole 14a5 of the first receiving plate portion 14a1.
Further, the pressure cooker lid 13 is not provided with the second exhaust hole 13d that is necessary when attaching the first receiving pan portion 14a1.
A water injection hole 13e and a drain hole 13f are provided in a portion of the pressure cooker lid 13 that forms the second space sp2.
Therefore, in application example 5 using the second pressure reducing device 14b, the pressure cooker lid 13 needs the lower projecting portion 13c, the water injection hole 13e, and the drain hole 13f, as compared with the form not using the second pressure reducing device 14b.
In addition, in the same manner as in the case where the second decompression device 14b is not used, the pressure cooker lid 13 is provided with a pressure regulating valve (not shown) for discharging the steam inside the pressure cooker main body 11 and a safety valve (not shown). is desirable.

One end of the water injection pipe 14b5 is inserted into the water injection hole 13e.
One end of the water injection pipe 14b5 is provided with a spray nozzle for spraying cooling water supplied through the water injection pipe 14b5.
In the present embodiment, a spray nozzle using a single-fluid spray nozzle will be described, but a spray nozzle using an injector or a two-fluid spray nozzle may also be used.
One end of the water injection pipe 14b5 is arranged in the second space sp2 in such a positional relationship that the tip of the spray nozzle faces upward.
A cooling water supply device 14b6 is attached to the other end of the water injection pipe 14b5 via a check valve (not shown).
The check valve has a structure that prevents the internal liquid from flowing out (backflowing) from the second space sp2 through the water injection pipe 14b5.

The cooling water supply device 14b6 is a device that supplies cooling water to the second space sp2.
The cooling water supply device 14b6 may be a device that stores cooling water and discharges the stored cooling water with a pump, or may be a faucet that discharges tap water.

One end of the drain pipe 14b7 is inserted into the drain hole 13f.
One end of the drain pipe 14b7 is arranged in the second space sp2 such that the one end of the drain pipe 14b7 is positioned near the bottom surface of the second receiving pan 14b1.
As a result, the liquid accumulated in the second receiving tray portion 14b1 can also be discharged efficiently.
The other end of the drain pipe 14b7 is arranged near the drain port of the kitchen or kitchen sink.

During the decompression step, cooling water is supplied from the cooling water supply device 14b6 to the second space sp2 through the water injection hole 13e and the water injection pipe 14b5, and the cooling water is sprayed from the spray nozzle (see FIG. 17). .
The liquid accumulated in the second space sp2 is discharged through the drain hole 13f and the drain pipe 14b7.

Also, if the pressure is suddenly reduced by exhausting the pressure through a pressure regulating valve, the boiling point will drop and the soup will be agitated and may become cloudy.
As the cooling water passes through the second space sp2 between the pressure cooker body 11 and the pressure cooker lid 13, the second space sp2 is cooled. As the temperature of the second space sp2 decreases, the temperature of the area inside the pressure cooker body 11 other than the second space sp2 decreases, and the pressure in that area also decreases gradually.
As a result, the temperature of the pressure cooker main body 11 can be quickly lowered more easily than in the case where the second decompression device 14b is not provided.
In addition, since the pressure can be reduced more gradually than when the pressure is reduced by exhaust, it is possible to suppress stirring of the soup.
Moreover, since the pressure cooker lid 13 is provided with a water cooling device (second decompression device 14b), the structure of the pressure cooker main body 11 can be simplified compared to the form in which the pressure cooker main body 11 is provided with a water cooling device.

In particular, the mist-like cooling water is heat-exchanged with the gas (air or steam) inside the second space sp2, thereby cooling the high-temperature gas and quickly (efficiently) increasing the temperature inside the pressure cooker body 11. can be lowered. That is, the time from when the heating is stopped until the pressure cooker lid 13 can be opened can be shortened.

After the decompression process is completed, the pressure cooker lid 13 is removed from the pressure cooker main body 11 (lid removing process).
Further, the air in the space surrounded by the extraction container 23 and the container lid 23a is discharged by the pump 25 while the first valve 19 is opened by operating the pump 25 (discharging step, see FIG. 18).
When the space surrounded by the extraction container 23 and the container lid 23a becomes negative pressure, part of the liquid and ingredients in the pressure cooker main body 11 flows through the soup discharge pipe 21 into the extraction container 23.

The pressure cooker lid 13 having the first decompression device 14a of Application 4 and the second decompression device 14b of Application 5 may be held by the lid holding portion 11c of Application 1. FIG.
In this case, the addition of the decompression device 14 makes it possible to reduce the user's burden of lifting the pressure cooker lid 13, which increases in weight.
