Description

[Technical Field]

[0001] The present invention relates to a liquid extraction device and the like. [Background technology]

[0002] Conventionally, methods for extracting soup have been proposed, such as those disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-056142 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there have been cases where parts of the food being cooked have clogged the filter, preventing smooth extraction of the liquid.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a liquid extraction device or the like that can smoothly extract liquid. [Means for solving the problem]

[0006] The liquid extraction device of the present invention is arranged inside a pot body and comprises a first structure that sucks in at least the liquid from the food to be cooked inside the pot body from below, and a second structure that discharges the sucked-in liquid from at least one of the side and above.

[0007] Compared to a configuration in which the food to be cooked is sucked into the liquid extractor from the side or above, the possibility of the food to be cooked clogging is reduced, making it easier to maintain smooth liquid extraction.

[0008] Preferably, the liquid supply device comprises a lower portion. As the first structure, a first hole penetrating in the up-down direction is provided in the bottom of the lower portion.

[0009] The food to be cooked is sucked into the liquid extractor from below through the first hole provided in the bottom. Therefore, compared to a configuration in which the food to be cooked is sucked into the liquid extractor from the side or above, the food to be cooked is less likely to clog the first hole, making it easier to maintain smooth liquid extraction.

[0010] More preferably, a first recessed area recessed upward is formed on the lower surface of the bottom portion. The first hole is provided in the first recessed area.

[0011] In comparison with a configuration in which the first holes are formed on a flat surface without a first recessed region, the food to be cooked flows more easily and can more easily flow into the first holes.

[0012] Preferably, a downwardly extending convex portion is formed on the lower surface of the bottom portion in an area closer to the edge than the area where the first hole is located. The vertical dimension of the protrusion is equal to or smaller than the diameter of the first hole.

[0013] A gap can be formed upstream of the first hole. Objects that have difficulty passing through the first hole can be trapped in the gap, making it difficult for them to reach the first hole. This reduces the possibility of the object clogging the first hole and makes it easier to maintain smooth liquid extraction.

[0014] Preferably, the liquid extraction device further comprises a first upper part removably attached to the lower part and covering an upper part of the lower part. As the second structure, an extractor-side discharge portion is provided on at least one of a first upper surface of the first upper portion and a cylindrical first side portion extending downward from the first upper surface or extending upward from the bottom portion.

[0015] More preferably, the area of ​​the lower portion other than the bottom portion, the first side portion, and the first upper portion do not have holes for absorbing at least the liquid of the object to be cooked.

[0016] Preferably, the liquid extraction device further comprises a second upper part removably attached to the lower part. The second upper portion is composed of a first region covering the upper portion of the lower portion and a second region formed around the first region. As the second structure, an extractor-side discharge portion is provided on at least one of a second upper surface in the first region of the second upper portion and a cylindrical first side portion extending downward from the second upper surface or extending upward from the bottom portion.

[0017] Among the objects to be cooked, those that have difficulty passing through the first hole 31a2 are retained in the second hole, making it difficult for them to reach the first hole, reducing the possibility of the objects to be cooked clogging the first hole and making it easier to maintain smooth liquid extraction.

[0018] More preferably, the area other than the bottom portion of the lower portion, the first side portion, and the first area of ​​the second upper portion do not have holes for absorbing at least the liquid of the object to be cooked.

[0019] Preferably, the second region is provided with a second hole having a larger diameter than the first hole and penetrating in the vertical direction.

[0020] More preferably, a second recessed region recessed downward is formed on the upper surface of the second region of the second upper portion. The second hole is provided in the second recessed area.

[0021] Compared to a configuration in which the second holes are formed on a flat surface without a second recessed region, the food to be cooked flows more easily and can easily flow into the second holes.

[0022] Preferably, a downwardly extending convex portion is formed on the lower surface of the bottom portion in an area closer to the edge than the area where the first hole is located. The vertical dimension of the protrusion is equal to or smaller than the diameter of the first hole. A leg portion extending downward is formed in a surface below the second region of the second upper surface, in a region closer to the edge than the region where the second hole is located. When the liquid extraction device is placed on the pot body, the convex portion and the leg portion come into contact with the bottom surface of the pot body, and a gap equal to the height of the convex portion is formed between the lower surface of the lower part and the bottom surface of the pot body.

[0023] Compared to a configuration in which the second upper surface is supported only by the lower part, the second upper surface can be stably supported by the lower part and the legs, which reduces the possibility of the liquid extractor being damaged or clogged even if the process of opening the lid and crushing or stirring the food to be cooked is included.

[0024] Preferably, the second upper portion includes a pipe passing portion configured as a notch or a hole through which a communication pipe passes, the communication pipe having one end attached to the extractor-side discharge portion.

[0025] The communicating pipe can be easily arranged inside the pot body without causing physical interference with the second upper surface.

[0026] Preferably, the second upper portion includes a grip portion arranged in a region of the second region of the second upper surface closer to the edge than a region where the second hole is located.

[0027] Compared to a configuration without a grip portion, the second upper portion can be held more easily.

[0028] More preferably, the second upper portion includes a member for preventing the grip portion from coming off. The gripping portion and the anti-slip member are arranged in the second region in a state in which they can move up and down.

[0029] When not in use, the handle protrudes less upward from the second upper surface, making it less likely to interfere with the movement of food to be cooked.

[0030] The pot of the present invention comprises a pot body, and a liquid extraction device that is arranged inside the pot body and has a first structure that sucks in at least the liquid from the food being cooked inside the pot body from below, and a second structure that discharges the sucked-in liquid from at least one of the side and above. [Effects of the Invention]

[0033] The first embodiment will be described below with reference to the drawings. The embodiments are not limited to the following embodiments. Furthermore, the content described in one embodiment is generally applicable to other embodiments as well. Furthermore, the embodiments and modifications can be combined as appropriate.

[0034] (Pot 1) The pot 1 in the first embodiment is a pressure cooker including a pot body 10, a lid 20, and a liquid extractor 30 (lower portion 31, first upper portion 33) (see FIGS. 1 to 5). However, the pot 1 is not limited to a pressure cooker.

[0035] Note that the cross-sectional configuration diagrams of Figures 1 and 2 show the shape of the characteristic parts in the first embodiment in a schematic manner to make it easier to understand, and the specific shapes of some parts, such as the first hole 31a2, do not match those of the oblique views of Figures 3 to 5.

[0036] (Pot body 10) The pot body 10 is a container for holding food to be cooked. The pot body 10 accommodates a liquid extractor 30 therein. A hole (pot body-side discharge part 15) is provided on the side of pot body 10 for discharging the liquid extracted by liquid extractor 30 to the outside.

[0037] (Lid 20) The lid 20 is a lid that covers the top opening of the pot body 10. The lid 20 is provided with a pressure regulator (not shown). The pressure adjusting device is used to adjust the internal pressure of pot 1 so that it does not exceed a predetermined pressure (for example, 2 atmospheres). The lid 20 is provided with a lid closure. The lid sealing member is made of a packing or the like, and when it expands due to a temperature rise caused by heating, it comes into contact with the inner wall of the pot body 10 and seals the gap between the upper end of the pot body 10 and the lower end of the lid 20. In the first embodiment, the lid sealing member is attached to the bottom of the lid 20, but the lid sealing member may also be attached to the top of the pot body .

[0038] (Liquid extraction device 30 of the first embodiment) The liquid extractor 30 of the first embodiment has a lower part 31 and a first upper part 33 .

[0039] (Lower part 31 of the first embodiment) The lower portion 31 includes a bottom portion 31a, a first side portion 31b, an extractor-side discharge portion 31c, and a bottom sealing member 32a.

[0040] The bottom portion 31a has a substantially circular plate shape. The first side portion 31b has a generally cylindrical shape and extends upward from the edge of the upper surface of the bottom portion 31a. The bottom portion 31a and the first side portion 31b are integrally formed.

[0041] A first recessed region 31a1 recessed upward is formed on the lower surface of the bottom portion 31a. The first recessed regions 31a1 are formed in the shape of grooves or the like, and a plurality of first recessed regions 31a1 are provided concentrically. The first recessed region 31a1 has a plurality of holes (first holes 31a2) formed therein, which penetrate the bottom portion 31a in the vertical direction.

[0042] A plurality of downwardly extending protrusions 31a3 are formed on the lower surface of the bottom portion 31a in an area closer to the edge than the area where the first holes 31a2 are located. The vertical dimension (height) of the protrusion 31a3 is approximately the same as or shorter than the diameter of the first hole 31a2. In the first embodiment, an example in which a plurality of protrusions 31a3 are provided will be described, but the protrusion 31a3 may be configured with one hollow cylindrical shape or the like.

[0043] The first side portion 31b is provided with a hole (extraction device side discharge portion 31c) for discharging the liquid sucked up by the bottom portion 31a to the outside.

[0044] The inner wall of the first side portion 31b is provided with a bottom sealing member 32a. The bottom sealing member 32a is made of a packing or the like, and contacts the outer wall of the first fitting wall 33b of the first upper part 33 to seal the gap between the lower part 31 and the first upper part 33. In a second embodiment described later, the bottom sealing member 32a contacts the outer wall of the second fitting wall 35b of the second upper portion 35, sealing the gap between the lower portion 31 and the second upper portion 35.

[0045] In the first embodiment, an example is shown in which the bottom sealing member 32a is provided on the first side portion 31b of the bottom portion 31a, but it may also be provided on the first mating wall 33b of the first upper portion 33 and the second mating wall 35b of the second upper portion 35 described later.

[0046] One end of a communication pipe 32b is attached to the extractor-side discharge portion 31c. The other end of communication pipe 32b communicates with discharge portion 15 on the pan body side.

[0047] (First Upper Section 33) The first upper portion 33 includes a first upper surface 33a and a first fitting wall 33b.

[0048] (First top surface 33a) The first upper surface 33a has a substantially disk shape and functions as a lid that covers the upper part of the lower portion 31.

[0049] (1st fitting wall 33b) The first fitting wall 33b has a generally cylindrical shape that extends downward from the lower surface of the first upper surface 33a. The outer diameter of the first fitting wall 33b is approximately equal to the inner diameter of the first side portion 31b so that the first fitting wall 33b fits inside the first side portion 31b.

[0050] (Arrangement of first holes 31a2) The area of ​​the lower portion 31 other than the bottom portion 31a, the first side portion 31b, and the first upper portion 33 do not have holes (holes corresponding to the first holes 31a2) for absorbing at least the liquid of the food to be cooked. That is, the hole (first hole 31a2) for sucking the material to be cooked into the liquid extractor 30 is provided only in the bottom portion 31a.

[0051] (Liquid extraction flow) With first upper part 33 attached to lower part 31, bottom part 31a is placed on pot body 10. When the lower part 31 is placed on the pot body 10, the convex part 31a3 comes into contact with the bottom surface of the pot body 10, and a gap S equal to the height of the convex part 31a3 is formed between the lower surface of the bottom part 31a and the bottom surface of the pot body 10. One end of communication pipe 32b is attached to extraction device side discharge portion 31c, and the other end of communication pipe 32b is connected to pan body side discharge portion 15. An object to be cooked is placed inside pot body 10, and cooking is carried out with lid 20 attached to pot body 10 and pot body-side discharge part 15 closed.

[0052] After cooking is completed, when the pot body side discharge section 15 is opened, the liquid (such as soup) produced inside the pot body 10 and any solids having dimensions smaller than the gap S are sucked into the liquid extraction device 30 through the gap S and the first hole 31a2 by negative pressure, and are then discharged to the outside through the connecting pipe 32b and the pot body side discharge section 15. Solids having dimensions larger than gap S do not pass between bottom 31a and the bottom surface of pan body 10 or through first hole 31a2, and are therefore not discharged via pan body-side discharge portion 15.

[0053] (Method of providing negative pressure) When extracting liquid, if the lid 20 is attached to the pot body 10, the liquid can be discharged to the outside by opening the pot body side discharge part 15 due to negative pressure. However, the liquid extraction may be performed with the lid 20 removed from the pot body 10. In this case, the liquid may be sucked out using a pump (not shown) or the like, and the liquid may be discharged to the outside via the liquid extractor 30.

[0054] (Effect of providing first holes 31a2 only on the lower surface of liquid extractor 30) The food to be cooked is sucked into the liquid extraction device 30 from below through the first hole 31a2 provided in the bottom 31a, and is discharged outside the pot 1 through the extraction device side discharge section 31c, the connecting pipe 32b, and the pot body side discharge section 15. Therefore, compared to a configuration in which the food to be cooked is sucked into the liquid extractor 30 from the side or above, the food to be cooked is less likely to clog the first holes 31a2, making it easier to maintain smooth liquid extraction.

[0055] (Effect of Providing the First Hole 31a2 in the First Recessed Region 31a1) In comparison with a configuration in which the first holes 31a2 are formed on a flat surface without the first recessed regions 31a1, the food to be cooked can flow more easily and easily into the first holes 31a2.

[0056] (Effect of Providing the Convex Part 31a3 with a Height Less than the Diameter of the First Hole 31a2) A gap S can be formed upstream of the first hole 31a2. Among the objects to be cooked, those that have difficulty passing through the first hole 31a2 can be retained in the gap S, making it difficult for them to reach the first hole 31a2, reducing the possibility of the objects to be cooked clogging the first hole 31a2 and making it easier to maintain smooth liquid extraction.

[0057] (Application example of the liquid extraction device 30 of the first embodiment) Although the liquid extractor 30 (lower part 31 and first upper part 33) of the first embodiment has been described as having a substantially cylindrical shape, the shape is not limited to a substantially cylindrical shape. For example, the bottom part 31a and the first upper surface 33a may be substantially rectangular, and the liquid extractor 30 of the first embodiment may be substantially rectangular.

[0058] (Application example of first side portion 31b) Although the example in which the first side portion 31b is integrally formed with the bottom portion 31a has been described, the first side portion 31b may also be integrally formed with the first upper surface 33a. In this case, the first side portion 31b extends downward from the first upper surface 33a, and a member corresponding to the first fitting wall 33b is provided on the bottom portion 31a and extends upward from the bottom portion 31a.

[0059] (Pot 1 of the second embodiment) Pot 1 in the second embodiment includes pot body 10, lid 20, and liquid extractor 30 (lower portion 31, second upper portion 35) (see FIGS. 6 to 10).

[0060] The cross-sectional configuration diagrams of Figures 6 and 7 show the shape of the characteristic parts in the second embodiment in a schematic manner to make it easier to understand, and the specific shapes of some parts, such as the second hole 35a2, do not match those of the oblique views of Figures 8 to 10.

[0061] (Pot body 10 and lid 20 of the second embodiment) The configurations of pot body 10 and lid 20 of the second embodiment are the same as those of pot body 10 and lid 20 of the first embodiment.

[0062] (Liquid extraction device 30 of second embodiment) The liquid extractor 30 of the second embodiment has a lower part 31 and a second upper part 35 .

[0063] (Lower part 31 of the second embodiment) The configuration of the lower portion 31 in the second embodiment is the same as the configuration of the lower portion 31 in the first embodiment.

[0064] (Second Upper Section 35) The second upper portion 35 includes a second upper surface 35a, a second fitting wall 35b, a second side portion 35c, a leg portion 35d, a pipe insertion portion 35e, a grip portion 35f, and a slip-out prevention member 35g. The second upper surface 35a, the second fitting wall 35b, the second side portion 35c, and the leg portion 35d are integrally formed.

[0065] (Second top surface 35a) The second upper surface 35a has a generally circular disk shape that is larger than the first upper surface 33a. The second upper surface 35a is composed of a first region A1 and a second region A2. The first area A1 of the second upper surface 35a is a circular area having approximately the same size as the first upper surface 33a, and functions as a lid that covers the upper part of the lower portion 31. The second region A2 of the second upper surface 35a is a substantially doughnut-shaped region formed around the first region A1. The first area A1 and the second area A2 are divisions for explaining the invention and are integrally configured. 8 and 9, for convenience, the boundary between the first area A1 and the second area A2 is indicated by a dotted line.

[0066] A second recessed region 35a1 recessed downward is formed on the surface above the second region A2 of the second upper surface 35a. The second recessed regions 35a1 are formed in the shape of grooves or the like, and a plurality of second recessed regions 35a1 are provided concentrically.

[0067] The second recessed region 35a1 has a plurality of holes (second holes 35a2) formed therein that penetrate the second region A2 of the second upper surface 35a in the up-down direction. The diameter of the second hole 35a2 is larger than the diameter of the first hole 31a2. The diameter of the second hole 35a2 is larger than the vertical dimension of the protrusion 31a3.

[0068] (Second fitting wall 35b) The second fitting wall 35b has a generally cylindrical shape that extends downward from the lower surface of the first region A1 of the second upper surface 35a. The outer diameter of the second fitting wall 35b is approximately equal to the inner diameter of the first side portion 31b so that the second fitting wall 35b fits inside the first side portion 31b.

[0069] (Second side portion 35c) The second side portion 35c has a generally cylindrical shape and extends upward from the edge of the upper surface of the second region A2 of the second upper surface 35a. The outer diameter of second side portion 35c is approximately equal to the inner diameter of pan body 10 so that there is almost no space between second side portion 35c and the inner wall of pan body 10.

[0070] (leg 35d) A plurality of legs 35d extending downward are formed in a region on the lower surface of the second region A2 of the second upper surface 35a that is closer to the edge than the region where the second hole 35a2 is located. When the second embodiment of the liquid extraction device 30 (lower part 31, second upper part 35) is placed on the pot body 10, the convex part 31a3 and the leg part 35d come into contact with the bottom surface of the pot body 10, and a gap S equal to the height of the convex part 31a3 is formed between the lower surface of the bottom part 31a of the lower part 31 and the bottom surface of the pot body 10. In the second embodiment, an example in which a plurality of leg portions 35d are provided will be described, but the leg portion 35d may be configured with one hollow cylindrical shape or the like.

[0071] (Pipe passing part 35e) The pipe insertion portion 35e is constituted by a notch or a hole formed in the edge portion of the second region A2 of the second upper surface 35a and the second side portion 35c. The communication pipe 32b passes through the pipe passing portion 35e.

[0072] (Gripping part 35f, removal prevention member 35g) The gripping portion 35f has a generally U-shape when viewed horizontally, and the slip-out prevention member 35g is made up of a rod-shaped member that connects the ends of the gripping portion 35f. The gripping portion 35f and the slip-out prevention member 35g are arranged in a vertically movable state in a region of the second region A2 of the second upper surface 35a that is closer to the edge than the region where the second hole 35a2 is located. The grip portion 35f is used when carrying the second upper portion 35. The slip-out prevention member 35g is used to prevent the grip portion 35f from slipping out. When the grip portion 35f is not being held, the slip-out prevention member 35g pulls down the grip portion 35f, so that the grip portion 35f comes into contact with the upper surface of the second upper surface 35a. When the gripping portion 35f is lifted, the gripping portion 35f pulls up the fall-off prevention member 35g, and the fall-off prevention member 35g comes into contact with the lower surface of the second upper surface 35a.

[0073] FIG. 8 shows a state in which the left-side fall-off prevention member 35g is positioned downward and the right-side fall-off prevention member 35g is pulled upward. FIG. 9 shows a state in which the left grip portion 35f is pulled up and the right grip portion 35f is positioned downward. FIG. 10 shows the state in which the drop-out prevention members 35g on both sides are pulled up.

[0074] (Arrangement of first holes 31a2) The area other than the bottom 31a of the lower part 31, the first side part 31b, and the first area A1 of the second upper part 35 do not have holes (holes corresponding to the first holes 31a2) for absorbing at least the liquid of the food to be cooked. That is, the hole (first hole 31a2) for sucking the material to be cooked into the liquid extractor 30 is provided only in the bottom portion 31a.

[0075] (Liquid extraction flow) With second upper part 35 attached to lower part 31, bottom part 31a is placed on pot body 10. When the lower part 31 is placed on the pot body 10, the convex part 31a3 and the leg part 35d come into contact with the bottom surface of the pot body 10, and a gap S equal to the height of the convex part 31a3 is formed between the lower surface of the bottom part 31a and the bottom surface of the pot body 10. One end of communicating pipe 32b is attached to extractor-side discharge portion 31c, and communicating pipe 32b passes through pipe passing portion 35e, with the other end of communicating pipe 32b communicating with pan body-side discharge portion 15. An object to be cooked is placed inside pot body 10, and cooking is carried out with lid 20 attached to pot body 10 and pot body-side discharge part 15 closed.

[0076] Most of the solid portions of the food to be cooked are located above the second upper surface 35a. Of the food to be cooked, liquid and solids smaller than the second holes 35a2 pass through the second holes 35a2 and are positioned below the second upper surface 35a.

[0077] After cooking is completed, when the pot body side discharge section 15 is opened, the liquid (such as soup) produced inside the pot body 10 and any solids having dimensions smaller than the gap S are sucked into the liquid extraction device 30 through the gap S and the first hole 31a2 by negative pressure, and are then discharged to the outside through the connecting pipe 32b and the pot body side discharge section 15. Solids having dimensions larger than gap S do not pass between bottom 31a and the bottom surface of pan body 10 or through first hole 31a2, and are therefore not discharged via pan body-side discharge portion 15.

[0078] (Effect of Providing the Second Upper Section 35 Including the Second Region A2) Second holes 35a2 can be formed upstream of first holes 31a2. Food items that have difficulty passing through first holes 31a2 can be retained in second holes 35a2, making them less likely to reach first holes 31a2. This reduces the possibility of food items clogging first holes 31a2 and makes it easier to maintain smooth liquid extraction.

[0079] (Effect of Providing Second Holes 35a2 in Second Recessed Region 35a1) Compared to a configuration in which the second holes 35a2 are formed on a flat surface without the second recessed regions 35a1, the food to be cooked can flow more easily and easily into the second holes 35a2.

[0080] (Effect of providing leg portion 35d) Compared to a configuration in which second upper surface 35a is supported only by lower portion 31, second upper surface 35a can be stably supported by lower portion 31 and legs 35d. Therefore, even if a process of opening lid 20 and crushing or stirring the food to be cooked is performed, the possibility of damage or clogging of liquid extractor 30 can be reduced. However, legs 35d may be omitted.

[0081] (Effect of providing the pipe-through portion 35e) Communication pipe 32b can be easily disposed inside pot body 10 without causing physical interference with second upper surface 35a.

[0082] (Effect of Providing the Grip 35f) Compared to a configuration in which the grip portion 35f is not provided, the second upper portion 35 can be held more easily.

[0083] (Effect of providing the anti-slip member 35g) When not in use, the upward protrusion of the gripping portion 35f from the second upper surface 35a is reduced, making it less likely to interfere with the movement of the food to be cooked.

[0084] (Application example of first side portion 31b) Although an example in which the first side portion 31b is integrally formed with the bottom portion 31a has been described, the first side portion 31b may also be integrally formed with the first region A1 of the second upper surface 35a.
