Description

  The present invention relates to a pan that can be efficiently heated.

  Conventionally, like the patent document 1, the cooking container for a heating used in order to heat and cook a foodstuff is proposed.

JP 2004-89634 A

  However, the pot was heated only on the bottom surface where the hot air of the combustor was hit, and the side portion was not heated sufficiently.

  Therefore, the objective of this invention is providing the pan which can be heated efficiently.

  The pan according to the present invention is a pan body having a cylindrical side portion, and a ring-shaped member provided on the outside at the lower side of the pan body, and the pan body is placed on the combustor. In some cases, a heat induction ring is provided that guides hot air from the combustor upward and between the main body and the pan body.

  The heat induction ring guides the hot air from the combustor upward, making it easier for the hot air to hit the side of the pan body and warming it, compared to the case where there is no heat induction ring. Can be heated). Moreover, compared with the case where there is a cylinder part that covers most of the side part of the pan body, the combustion efficiency is lowered, but there is an advantage in reducing the material cost and the processing cost as much as the cylinder part can be omitted. In particular, when it is the size of a commercial pot, there is little processing cost for attaching the cylinder part and material cost for constituting the cylinder part, and even with one unit, a cost reduction merit of tens of thousands of yen can be obtained.

  Preferably, the heat induction ring is attached to the pan body via a member protruding from the lower side of the pan body.

  More preferably, one of the members protruding from the lower part of the side surface of the pan body is used as a discharge port.

  In addition, preferably, it further includes a cylindrical portion that is a cylindrical member that is attached above the heat induction ring and covers the side of the pan body, and the outside of the cylindrical portion is coated with a paint having a heat insulating effect. Applied.

  The hot air from the combustor rises through between the heat induction ring and the cylinder part and the side part of the pan body. Thereby, the flow from the lower part to the upper part of the hot air from the combustor can be formed along the outer shape of the pan body. In particular, since heat radiation from the side portion of the tube portion is hindered by the heat insulating paint, hot air from the combustor can be effectively used to warm the pan body. In addition, since the temperature of the outer surface of the tube portion is hardly increased by the heat insulating paint, there is an advantage that even if the tube portion is touched, an accident such as a burn is unlikely to occur.

  In addition, preferably, it further includes a cylindrical portion that is attached above the heat induction ring and covers the side portion of the pan body, protrudes from the upper side of the pan body, and sandwiches the cylindrical portion with the heat induction ring At least one of the upper part of the flange or the cylinder part has a plurality of exhaust holes, and the hot air from the combustor passes between the heat induction ring or the cylinder part and the side part of the pan body, and a plurality of exhausts. It is discharged through the hole.

  The hot air from the combustor rises through between the heat induction ring and the cylinder part and the side part of the pan body, and is released to the outside through the exhaust hole. Thereby, the flow from the lower part to the upper part of the hot air from the combustor can be formed along the outer shape of the pan body.

  More preferably, it further includes a sealing member that seals the exhaust hole.

  By adjusting the number and position of the exhaust holes to be sealed, it is possible to adjust the speed and direction of the flow of hot air from the combustor passing between the heat induction ring and the cylinder part and the side part of the pan body. It becomes possible. For this reason, if the number and position of the exhaust holes to be sealed are adjusted in consideration of the size of the pan body, the performance of the combustor, the nature of the liquid to be put into the pan body, etc., the pan body can be heated with optimum thermal efficiency. Is possible. Moreover, since hot air is exhausted from the exhaust hole, the position of the exhaust hole to be sealed can be adjusted so that the cook does not receive hot air.

  More preferably, the inner surface of the exhaust hole is threaded and a screw is used as the sealing member.

  It is easy to put on and take off, and it is difficult to come off at the time of wearing, and reliable sealing becomes possible.

  Moreover, Preferably, the discharge port is provided in the lower part of the pan body, and the valve attached to the discharge port is mounted outside the heat induction ring.

  Since the hot air from the combustor can be blocked by the heat induction ring, the member (valve) outside the heat induction ring can be blocked.

  The heat induction ring of the pan according to the present invention is a ring-shaped member provided on the outside at the lower side of the pan body having a cylindrical side portion, and the pan body is placed on the combustor. In some cases, hot air from the combustor is guided upward and between the pan body.

  As mentioned above, according to this invention, the pan which can be heated efficiently can be provided.

  Hereinafter, the present embodiment will be described with reference to the drawings. The pan 1 in this embodiment includes a pan body 11, a lower discharge port 13, an upper discharge port 15, a heat induction ring 17, a cylindrical portion 19, a flange 21, an exhaust hole 23, a handle 25, and a strainer 27 (FIG. 1, (See FIGS. 2 and 4).

  The pan body 11 is a pan whose outer diameter hardly changes from the upper part to the lower part, such as a small pan, and the upper part is provided with a sealing mechanism 11a for attaching a pressure-resistant lid 50 for using the pan body 11 as a pressure cooker. The pressure-resistant lid 50 is attached to the pan body 11 with the packing 12 being sandwiched. 1, 2, 6, 7, 8, 9, 10, 11, 12, and 13 show the state before the pressure-resistant lid 50 is attached to the pan body 11, and the sealing mechanism Although 11a is abbreviate | omitted, specifically, the pressure | voltage resistant lid | cover 50 as is shown by FIGS. 14-16 is attached to the pan main body 11 via the sealing mechanism 11a.

  A side wall 51 that covers the upper part and the side part of the upper end of the pan body 11 is provided on the outside of the pressure-resistant lid 50 and in contact with the upper end (opening) of the pan body 11 when attached to the pan body 11 ( 14 to 16). Usually, the space between the pan body 11 and the pressure-resistant lid 50 is sealed by the packing 12. However, when the packing 12 is damaged due to deterioration over time, contents such as steam and soup may jump out from the damaged portion through the gap between the pan body 11 and the pressure-resistant lid 50. Further, it can be prevented from being ejected upward or laterally (container plane centrifugal direction), and can be discharged vertically downward from the gap between the side wall 51 and the upper end of the pan body 11.

  At the time of attachment to the pan body 11, an edge 53 that protrudes inward in the radial direction is provided in the vicinity of the portion that contacts the pan body 11 inside the pressure-resistant lid 50. By aligning the portion formed by the edge portion 53 and the inner wall of the pressure-resistant lid 50 with a convex portion 25a provided on the upper portion of the handle 25 to be described later, the pressure-resistant lid 50 can be latched to the handle 25. (See FIG. 16).

  The lower discharge port 13 is a cylindrical object used for at least one of the drains in order to extract the liquid inside the pot body 11, and is provided at the lower part of the pot body 11. A lower outlet valve 33 is attached so as to extend to the outside of a heat induction ring 17 (to be described later) and flow in the horizontal direction (see FIG. 3). In addition, the lower discharge port 13 may have a form in which a cylindrical object is attached to a hole instead of a cylindrical object. It is desirable to provide the lower outlet 13 at a lower position of the pan body 11 so that the liquid stored at the bottom of the pan body 11 can be discharged without stagnation.

  A ball valve having a spherical disc (valve element) is used for the lower discharge valve 33. The lower outlet valve 33 may be a valve using another structure such as a gate valve, but it is desirable to use a ball valve. Since it is attached to the lower part of the pan body 11, it is difficult to attach the valve so that the liquid flows vertically downward due to physical interference with the combustor 40 and the like, and it is necessary to attach the valve so that the liquid flows horizontally. This is to reduce the possibility that solid matter such as bone powder contained in the liquid will stay in the vicinity of the disc when the valve is attached in the horizontal direction. The lower outlet valve 33 preferably has a structure that can be divided into three parts or the like in order to improve the workability of maintenance (internal cleaning or the like).

  The projecting portion 14 has a cylindrical shape (or a cylindrical object) having substantially the same outer shape as that of the lower discharge port 13, and one or more are provided in the lower portion of the pan body 11 (three in this embodiment, see FIG. 4). The cylindrical body of the lower discharge port 13 and the protrusion 14 are used for connection to a heat induction ring 17 described later. As shown in FIG. 2 and the like, the protruding portion 14 may have a form that penetrates the heat induction ring 17 and the cylindrical portion 19, or a portion that does not penetrate the cylindrical portion 19 and has an inner wall of the cylindrical portion 19. The form which protrudes to may be sufficient.

  The upper outlet 15 discharges a part of the gas in the inner space of the pan body 11 and the pressure-resistant lid 50 to lower the internal pressure (for decompression), and is a cylinder used for at least one of extracting the internal liquid. An upper outlet valve 35 is attached via a pipe 36 so that a gas or liquid flows vertically downward in the vertical direction.

  The upper outlet valve 35 does not need to consider physical interference with other devices, and may be attached to flow in the horizontal direction or may be attached to flow downward in the vertical direction. However, it is desirable to adopt a ball valve in order to reduce the possibility of solids staying when mounted so as to flow in the horizontal direction. When it is attached so as to flow downward in the vertical direction, there is no problem even if a valve having another structure is adopted.

  When the upper discharge port 15 is used for lowering the internal pressure of the pan body 11, the upper discharge port 15 has a suction port at the top and a lower portion so that the liquid inside the pan body 11 is not taken into the upper discharge port 15. It is desirable to attach a liquid ingress prevention member 37 having a weight inside the upper outlet 15 (see FIG. 6). Due to the weight of the lower portion, the suction port always faces upward, and the liquid in the pan body 11 can be prevented from being discharged from the upper discharge port 15 through the suction port.

  When the upper outlet 15 is used for extracting the liquid inside the pan body 11, a filter (not shown) is provided at the tip, the tip is placed on the strainer 27, and the tip It is desirable to attach the liquid feeding member 38 which sends the liquid of the lower part of the pan main body 11 upward via the part inside the upper discharge port 15 (refer FIG. 7). At the same time, two or more upper discharge ports 15 may be provided so that the liquid intrusion preventing member 37 and the liquid feeding member 38 are attached.

  The heat induction ring 17 is a ring-shaped member provided on the outer side of the side of the pan body 11. When the pan body 11 is placed on the combustor 40, the heat induction ring 17 generates hot air from the combustor 40. It guides in the upward direction and between the pan body 11. The heat induction ring 17 has a hole 17 a that allows the lower discharge port 13 and the protrusion 14 to pass therethrough.

  The heat induction ring 17 is attached to the lower part of the pan body 11 by being fixed to the lower discharge port 13 or the protruding part 14 with screws or the like (see FIG. 4). However, you may attach to the pan main body 11 via the cylinder part 19 and the flange 21 which are mentioned later. The heat induction ring 17 protrudes downward from the bottom surface of the pan body 11 to the extent that it does not interfere with the physical interference with the combustor 40 that warms the pan body 11 and the introduction path of oxygen used for combustion. It is desirable to be attached to the pan body 11.

  The cylinder part 19 is a cylindrical member that covers the side part of the pan body 11, the flange 21 is a bowl-shaped member that protrudes from the upper part of the side surface of the pot body 11, and the cylinder part 19 is a pot in the vertical direction. It is sandwiched between the flange 21 provided on the upper side of the main body 11 and the heat induction ring 17 attached to the lower side of the pan main body 11 (see FIG. 2).

  The inner diameter of the heat induction ring 17 and the cylinder part 19 is larger than the outer diameter of the side part of the pan body 11, and the combustor 40 is interposed between the heat induction ring 17 and the cylinder part 19 and the side part of the pot body 11. A space through which hot air passes is formed.

  Hot air from the combustor 40 is guided upward by the heat induction ring 17, and the hot air is easily applied to the side of the pan body 11, and is about 15%, compared to the case without the heat induction ring 17. It becomes easy to warm the main body 11 (Efficient heating is possible, for example, in the form of FIG. 8 and FIG. 9, the time for boiling the water put in the pan main body 11 can be shortened by about 15%). Further, since hot air from the combustor 40 can be blocked by the heat induction ring 17, a member outside the heat induction ring 17 (for example, a lower exhaust hole valve 33 described later) can be blocked.

  The hot air guided upward by the heat induction ring 17 rises along the side part of the pan body 11 without escaping in the lateral direction by the cylindrical part 19, so the hot air also flows above the side part of the pan body 11. It is easy to warm the pot body 11 by about 25% compared to the case where there is no heat induction ring 17 or the cylinder part 19 (for example, in the form of FIG. 1 or FIG. The time for boiling water can be shortened by about 25%).

  It is desirable that the outer side of the cylindrical portion 19 be coated with a paint having a heat insulating effect.

  The flange 21 is provided with a ring-shaped member 21b to which the cylindrical portion 19 is attached at the lower part of the flange-shaped protruding portion 21a. The ring-shaped member 21b is provided with a plurality of exhaust holes 23 over the entire circumference (see FIG. 1).

  The hot air from the combustor 40 rises through between the heat induction ring 17 and the cylinder part 19 and the side part of the pan body 11 and is discharged to the outside through the exhaust hole 23. Thereby, the flow from the lower part to the upper part of the hot air from the combustor 40 can be formed along the outer shape of the pan body 11. In particular, since heat radiation from the side portion of the cylindrical portion 19 is hindered by the heat insulating paint, hot air from the combustor 40 can be effectively used to warm the pan body 11. Moreover, since the temperature of the outer surface of the cylinder part 19 is hardly increased by the heat insulating paint, there is an advantage that even if the cylinder part 19 is touched, an accident such as a burn is unlikely to occur.

  The exhaust hole 23 can also close (seal) the hole using a sealing member (see FIG. 1). In particular, when the inner surface of the exhaust hole 23 is threaded and the hole is closed using a screw as a sealing member, it is easy to attach and detach, and it is possible to perform reliable sealing that is difficult to come off during mounting.

  By adjusting the number and position of the exhaust holes 23 to be sealed, the speed and direction of the flow of hot air from the combustor 40 between the heat induction ring 17 and the cylindrical portion 19 and the side of the pan body 11 Can be adjusted. For this reason, if the number and position of the exhaust holes 23 to be sealed are adjusted in consideration of the size of the pan body 11, the performance of the combustor, the nature of the liquid to be put into the pan body 11, etc., the pan body with optimum thermal efficiency. 11 can be warmed.

  Moreover, since hot air is discharged | emitted from the exhaust hole 23, it is also possible to adjust the position of the exhaust hole 23 to seal so that a cook may not receive hot air.

  A U-shaped handle 25 is provided on the upper portion of the flange 21. When not in use, the gripped portion (upper end portion) of the handle 25 may be stored so as to approach the pan body 11, but the upper portion is fixed in a state of opening radially outward, and this is required. A convex portion 25a may be provided on the upper portion so that the pressure-resistant lid 50 can be hooked (see FIGS. 14 to 16). The form provided in the upper part of the flange 21 may be sufficient as the handle 25, and the form provided in the side part above the flange 21 of the pan main body 11 may be sufficient as it.

  The strainer 27 is a member having a hole 27a used for filtration or used for circulation between the upper part and the lower part of the strainer 27, and the inside of the pot body 11 (the inner wall of the pot body 11 or a part protruding from the inner wall, or In a state of being detachable from a portion recessed from the inner wall, it is arranged upstream of the lower discharge port 13 (so that the liquid that has passed through the strainer 27 flows through the lower discharge port 13). For example, the strainer 27 is a flat plate having a plurality of holes 27 a, and the periphery of the flat plate is placed on a portion protruding radially inward from the inner wall of the pan body 11. The portion where the strainer 27 and the pan body 11 are in contact with each other is preferably sealed with packing (not shown).

  Ingredients used for soup production are placed on the strainer 27. It is desirable to prepare strainers 27 having different sizes, positions, numbers, and shapes of holes 27a depending on the type of soup desired. The strainer 27 can be removed from the pan body 11 and replaced with another strainer 27 as necessary, or cleaning such as clogging can be performed.

  From the outlet (lower outlet 13) provided in the lower part, not only the liquid for extraction (soup) but also solids (for example, bone meal produced in the soup production process) flow out together, and such solids May clog the outlet. In this embodiment, since it can filter with the strainer 27 provided upstream from the lower discharge port 13, it becomes possible to reduce possibility that a solid substance will clog a discharge port.

  Since the solid matter is unlikely to flow downward through the hole 27a of the strainer 27, it is difficult for the solid matter to accumulate on the bottom portion inside the pan body 11. For this reason, it becomes possible to make low possibility that the bottom part inside the pot main body 11 will burn. Solids smaller than the holes 27a may flow to the lower part through the holes 27a of the strainer 27, but the bottom of the pan body 11 is convected by heating, and the small solids are light so that they are light. There is little possibility of being pressed, and the possibility of scoring can be reduced. Moreover, since the liquid inside the pan body 11 can be extracted (or discharged) from the discharge port (lower discharge port 13) provided in the lower portion of the pan body 11, solid matter that causes scorching is deposited on the bottom of the pan body 11. There is also a merit that is hard to collect.

  The pan body 11, the lower discharge port 13, the upper discharge port 15, and the flange 21 are integrally formed, for example, by casting of aluminum, or the lower discharge port 13, the upper discharge port 15, and the flange 21 are separate bodies. Attached to the pan body 11.

  A procedure for generating and extracting soup (for example, ramen soup) using the pot 1 in the present embodiment will be described. It arrange | positions so that the bottom of the pan main body 11 may contact the virtues 41 of the combustor 40 (refer FIG. 6, FIG. 7).

  A lower outlet valve 33 is attached to the lower outlet 13, and an upper outlet valve 35 is attached to the upper outlet 15. The valves for the lower outlet valve 33 and the upper outlet valve 35 are also closed. When the upper outlet 15 is used for decompression, a liquid intrusion prevention member 37 is attached to the inner side of the upper outlet 15 (see FIG. 6), and the liquid inside the pan body 11 is extracted. When used, the liquid feeding member 38 is attached inside the upper discharge port 15 (see FIG. 7).

  A strainer 27 having a hole 27 a suitable for a desired soup is attached to the inside of the pan body 11. Ingredients used to produce the soup are placed on the strainer 27. A liquid such as water used to produce the soup is introduced so that at least the ingredients are hidden by the liquid.

  After the pressure-resistant lid 50 is fixed to the upper part of the pan body 11, the combustor 40 is ignited. The hot air from the combustor 40 heats the bottom portion of the pan body 11 and also heats the side portion of the pan body 11 via the heat induction ring 17 and the cylindrical portion 19, via the unsealed exhaust hole 23. It is discharged outside.

  When a predetermined time elapses and a desired soup is produced, the lower outlet valve 33 is opened. From the lower outlet valve 33, the soup inside the pan body 11 and filtered through the hole 27a of the strainer 27 is extracted by the pressure inside the pan body 11 and the gravity of the soup.

  When the liquid intrusion prevention member 37 is attached to the inside of the upper outlet 15 and the upper outlet valve 35 is opened before the lower outlet valve 33 is opened, the internal pressure of the pan body 11 decreases. However, the boiling point is lowered and the liquid inside is boiled, so that stirring and emulsification are promoted. Since the degree of emulsification changes depending on the degree of liquid agitation, the soup having a desired degree of emulsification can be obtained by adjusting the degree of opening of the upper outlet valve 35.

  When the liquid feeding member 38 is attached to the inside of the upper outlet 15, the soup extraction can be performed through the upper outlet valve 35 without being performed through the lower outlet valve 33. I can do it. Since the lower outlet valve 33 uses a ball valve, it is difficult to finely adjust the flow rate flowing through the valve, but the upper outlet valve 35 can finely adjust the flow rate, so the flow rate can be finely adjusted to extract soup. It is effective when you want to do it. For example, in order to extract soup without emulsification, it is desirable to extract soup at a low speed so as not to stir. For this reason, it is easier to extract soup having a lower degree of emulsification by performing soup extraction using the upper discharge valve 35 than by using the lower discharge valve 33.

  In this embodiment, soup such as ramen is generated using a pressure cooker, the boiling point of the liquid enclosed in the pan body 11 can be increased, and the food can be heated at a higher temperature and higher pressure than usual. It becomes possible to produce the desired soup in time.

  Further, since the heat air from the combustor 40 is guided by the heat induction ring 17 or the like so as to hit the side of the pan body 11, the pan body 11 can be easily warmed and uniform as compared with the configuration without the heat induction ring 17 or the like. It is possible to transfer heat (so that the temperature difference between the lower part and the upper part is reduced).

  In addition, since the pan body 11 can be heated not only from the bottom but also from the side by the heat induction ring 17 or the like, it becomes possible to heat the pan body 11 with a smaller amount of heat compared to the form without the heat induction ring 17 or the like. The combination with 27 makes it possible to reduce the possibility of scorching of the bottom of the pan body 11.

  In addition, the lower outlet 13 and the upper outlet 15 make it possible to generate and extract soups with different degrees of emulsification.

  In addition, in this embodiment, although the pan 1 was demonstrated as a pressure cooker with which the pressure-resistant cover 50 is attached on the pan main body 11, it is not restricted to a pressure cooker, The cylindrical shape from which an outer diameter hardly changes from an upper part to a lower part. Even in the pan having the side portions, the effect of increasing the thermal efficiency by the heat induction ring 17, the cylindrical portion 19, and the exhaust hole 23 can be obtained. In addition, when the operation | work which extracts not a pressure cooker but internal lid | cover with a lid | cover closed does not generate | occur | produce, the form without the lower discharge port 13 and the upper discharge port 15 may be sufficient. When omitting the lower discharge port 13, instead of the lower discharge port 13, a projecting portion 14 having a columnar shape (or a cylindrical object) having substantially the same outer shape is provided, and the pot body 11 and the heat induction ring 17 are It is desirable to use it for connection.

  Moreover, in this embodiment, although the form which uses the heat induction ring 17 and the cylinder part 19 in order to guide the hot air from the combustor 40 to the side part of the pan body 11 was demonstrated, the cylinder part 19 was abbreviate | omitted and the pan body The effect of inducing hot air can be obtained by using only the ring-shaped member (heat induction ring 17) provided at the lower part of 11 (see FIGS. 8 and 9). In this case, compared with the case where the cylinder part 19 which covers most of the side part of the pan main body 11 is present, the combustion efficiency is lowered, but the cost of material costs and processing costs is as much as the cylinder part 19 and the ring-shaped member 21b can be omitted. There is down merit. In particular, when it is the size of a commercial pot, the processing cost for attaching the cylinder part 19 and the material cost for constituting the cylinder part 19 are small, and even with one unit, a cost reduction merit of tens of thousands of yen can be obtained.

  Moreover, although the exhaust hole 23 demonstrated the form formed in the ring-shaped member 21b of the flange 21, the form formed in the upper part of the cylinder part 19 may be sufficient, and this exhaust hole 23 is formed in both. May be used for attaching and positioning the flange 21 and the cylindrical portion 19.

  In addition, the strainer 27 may have a form in which only one flat plate is prepared, but it is also conceivable to make the number and shape of the strainers different.

  For example, the strainer 27 includes a disc portion 27b at a position lower than a position where the strainer 27 is attached to the pan body 11, and a hypotenuse portion 27c configured between the disc portion 27b and a position where the strainer 27 is attached to the pan body 11. (See FIG. 10). The disc portion 27b and the oblique side portion 27c form a truncated cone having an open upper surface. In this case, the oblique side 27c or a flange protruding radially outward from the oblique side 27c is placed on a portion protruding radially inward from the inner wall of the pan body 11 or the like. The portion where the strainer 27 and the pan body 11 are in contact with each other is preferably sealed with packing (not shown). Ingredients used for cooking are placed on the disc part 27b.

  The portion where the strainer 27 and the pan body 11 are in contact cannot be made lower than the portion where the lower discharge port 13 is provided in order to avoid physical interference with the lower discharge port 13. However, by making the strainer 27 into a shape constituted by the disc portion 27b and the oblique side portion 27c, compared to the case where the strainer 27 is constituted by a flat plate, only the dent using the oblique side portion 27c is used for cooking. The position for placing the ingredients to be used can be lowered, and the space between the strainer 27 and the bottom of the pan body 11 can be narrowed. At the time of cooking, it is necessary to add a liquid such as water to the extent that the ingredients are hidden, but it is possible to reduce the input amount of such liquid.

  As shown in FIG. 10, the hole 27a provided in the strainer 27 may be provided in the entire disk portion 27b and the oblique side portion 27c. However, the hole 27a is not provided in the disk portion 27b, and a hole is provided only in the oblique side portion 27c. A form of providing is also conceivable (see FIG. 11). In this case, although some flow is generated due to the expansion of deposition during heating, the liquid is hardly mixed between the space below the strainer 27 and the space above. For this reason, it becomes possible to cook the ingredients at the upper part of the strainer 27 in a state where it is difficult to mix with the liquid at the lower part of the strainer 27 (for example, tsukemen soup). In this case, the liquid is extracted through the upper discharge port 15, or when the pan 1 is not a pressure cooker, the lid is opened to extract the liquid from the top of the pan body 11, and the lower discharge port 13 Used for. That is, the hole 27a is not used for filtration, but is used for the circulation of the liquid between the upper part and the lower part of the strainer 27.

  If the space above the strainer 27 and the space below the strainer 27 are cut off without providing the hole 27a in the strainer 27, the material above the strainer 27 and the liquid below are prevented from mixing. However, in this case, it is necessary to supply liquid separately for the lower use than the strainer 27 and for the upper use than the strainer 27, and the work becomes complicated.

  Further, the strainer 27 is composed of a plurality of strainers, for example, a flat plate-shaped first strainer 27d and a second strainer having a circular plate portion 27b and a hypotenuse portion 27c disposed downstream of the first strainer 27d. 27e can be considered (see FIG. 12).

  When the hole 27a of the first strainer 27d is large and the hole 27a of the second strainer 27e is small, large solids are filtered by the first strainer 27d, and small solids that have passed through the first strainer 27d are filtered by the second strainer 27e. . Thereby, it is possible to extract a liquid having almost no solid matter from the lower discharge port 13. In this case, the holes 27a of the first strainer 27d and the second strainer 27e are mainly used for filtration.

  When the hole 27a of the first strainer 27d is small and the hole 27a of the second strainer 27e is the same as or larger than the hole 27a of the first strainer 27d, the space below the second strainer 27e is caused by deposition expansion during heating. However, the liquid in the space below the first strainer 27d and the material in the space above the first strainer 27e are considered to enter the space between the first strainer 27d and the second strainer 27e. It becomes possible to cook in a state where it is difficult to mix. In this case, the holes 27a of the first strainer 27d and the second strainer 27e are used not for filtration but for circulation of the liquid between the upper part and the lower part of the strainer 27.

  In either case, since it is difficult for the solid matter to enter below the second strainer 27e, it is possible to prevent the solid matter from collecting and scorching at the bottom of the pan body 11.

  When the strainer 27 is composed of a plurality of strainers, both strainers may be detachably disposed inside the pan body 11 (see FIG. 12), or one of the strainers ( For example, the second strainer 27e) disposed on the lower side is detachably disposed inside the pan body 11, and the other strainer (for example, the first strainer 27d disposed on the upper side) is disposed on one strainer. It may be arranged in a detachable state (see FIG. 13).

  Further, in order to prevent the strainer 27 from being bent by the weight of the contents or the like, for reinforcement, a support column is provided between the plurality of strainers or between the strainer and the bottom of the pan body 11 and in the center of the strainer 27. 27f may be provided (see FIG. 13).
