Description

  The present invention relates to a cooking device that heats and cooks a food set in a pan.

  If a cooked food is cooked with high heat using a heating cooker, spilling may occur. The spills that occur during cooking contain steam and viscous liquid or foamy substances. When sticky liquid substance or foamy substance comes out from the steam outlet hole of the lid of the heating cooker without being sufficiently removed, spilling occurs. A sticky liquid substance or foamy substance is a so-called “rice cake” of starch when cooking rice, and boiled juice when cooking boiled food.

  In order to prevent spilling, a steam unit is provided downstream of the steam passage of the lid, and the steam unit collects and separates the rice cake from the exhausted steam. (For example, see Patent Document 1).

JP2013-236725A

  In the heating cooker disclosed in Patent Document 1, the steam unit is arranged at the upper part of the lid, that is, at the most downstream side of the exhaust path. By installing the steam unit on the upper part of the lid, it is easy to clean the steam unit in which the separated and collected rice balls are stored. However, a large storage space is required in order to store a large amount of rice in the steam unit, and as a result, the installation space for the steam unit increases. In the upper part of the lid body, when a lid heating unit for heating the lid and a driving member for driving the pressure regulating valve are installed, the installation space for the steam unit is limited. Therefore, when the steam unit is installed on the upper part of the lid, it is difficult to increase the size of the steam unit, and if the large steam unit is installed on the upper part of the lid, there is a problem that the size of the lid is increased. .

  Moreover, since the sticky liquid substance and the foamy substance contain the umami component of the cooked product, there is a need to utilize the umami component by refluxing the liquid substance and the foamy substance to the pan. However, in the cooking device disclosed in Patent Document 1, the steam unit is arranged on the most downstream side of the steam passage, so that there is also a problem that the liquid substance is difficult to recirculate to the pan.

  Therefore, the technical problem to be solved by the present invention is that a storage device that separates and stores liquid substances generated during cooking has a cooking device configured to have a large storage space while preventing spillage. Is to provide.

The inner lid 30 includes a plate 34, and a frame member 32 is attached to the outer periphery of the plate 34. A seal member 33 that seals the inner peripheral portion of the upper end opening of the pan 3 is disposed on the lower (inner) side surface of the frame member 32. Engaging portions 33A and 33B (illustrated in FIGS. 2 and 3) that engage with engaged portions provided on the lower plate 22 are provided on the frame member 32, and the inner lid 30 is attached to the lid body 20. It is configured to be removable. In the present invention, the inner lid 30 is not limited to a configuration in which the inner lid 30 can be attached to and detached from the lid body 20, and an inner configuration in which the inner lid 30 cannot be detached from the lid body 20 can be adopted. In an integrated configuration in which the inner lid 30 cannot be detached from the lid body 20, a storage device 80 described later is attached to the lower surface of the inner lid 30, that is, the lower surface of the lid body 20.

  As shown in FIGS. 2 and 4, a first pressure regulating valve 35 and a second pressure regulating valve 36 are disposed on the upper surface side of the inner lid 30, and the inside of the pan 3 is formed by the first pressure regulating valve 35 and the second pressure regulating valve 36. It is possible to set the pressure at a pressure higher than the atmospheric pressure.

  The first pressure regulating valve 35 and the second pressure regulating valve 36 are pressure regulating mechanisms provided in the steam passage. The first pressure regulating valve 35 and the second pressure regulating valve 36 are respectively provided in a first pressure regulating valve housing portion (not shown) and a second pressure regulating valve housing portion 25 (shown in FIG. 1) formed on the lower plate 22 of the lid body 20. Contained. The first pressure regulating valve 35 and the second pressure regulating valve 36 include valve seats 35 </ b> B and 36 </ b> B disposed from the lower side, which is the pan 3 side, with respect to the inner lid 30. The valve seats 35B and 36B are respectively provided with vent holes 35C and 36C that serve as inlets of the steam passages. Also, a first pressure regulating valve flange 45 and a second pressure regulating valve flange 46 are provided at the lower ends of the valve seats 35B and 36B, respectively, so as to project radially outward so as to form an annular shape. The main body portions 35A and 36A of the first pressure regulating valve 35 and the second pressure regulating valve 36 disposed on the upper side of the inner lid 30 and the first of the valve seats 35B and 36B disposed on the lower side of the inner lid 30. The pressure regulating valve flange 45 and the second pressure regulating valve flange 46 are fixed to the inner lid 30 via the plate 34 and the valve seat base plate 40 of the inner lid 30. The main body portions 35A, 36A of the first pressure regulating valve 35 and the second pressure regulating valve 36 are respectively provided with communication holes 35G, 36G communicating with the first pressure regulating valve housing portion and the second pressure regulating valve housing portion 25, respectively. ing.

  The first pressure regulating valve 35 includes a valve body 35D for closing a vent hole 35C formed in the main body portion 35A, an operation receiving member 35F for moving the valve body 35D to a closed position (downward), and a space therebetween. And a spring 35E disposed in When the operation receiving member 35F moves downward by driving a stepping motor (not shown), the valve body 35D closes the vent hole 35C while applying the urging force of the spring 35E. Moreover, the pressure in the pan 3 can be controlled in the range of 1.00 to 1.30 atm by adjusting the moving amount of the operation receiving member 35F (the urging force by the spring 35E).

  In the second pressure regulating valve 36, a spherical member 36D for closing the vent hole 36C so as to be openable is disposed in the main body portion 36A so as to be able to roll. As the spherical member 36D, when the pressure in the pan 3 rises to, for example, 1.30 atm, the spherical member 36D has a weight that separates by rolling from above the vent hole 36C with the pressure of the steam. Further, when the spherical member 36D is driven to roll by a solenoid (not shown), the spherical member 36D is in an open state apart from the air hole 36C and a closed state located above the air hole 36C. And can be switched to.

  Inside the lid 20, a steam passage for exhausting steam generated from the pan 3 during cooking to the outside is formed. The vent holes 35C and 36C formed in each of the first pressure regulating valve 35 and the second pressure regulating valve 36 disposed in the inner lid 30 serve as steam inlets in the steam passage. After the steam from the pan 3 flows into the first pressure regulating valve 35 and the second pressure regulating valve 36, the heat radiation plate 24 and the inner lid 30 are opened from the lower end openings of the first pressure regulating valve accommodating portion and the second pressure regulating valve accommodating portion 25. Flows into the gap formed between the two. And the vapor | steam from the pan 3 flows in into the vapor | steam discharge part 29 arrange | positioned at the upper board 21 through the space | gap part. Then, the steam from the pan 3 passes through the steam discharge unit 29 and is discharged to the outside from an exhaust port formed in the steam discharge unit 29.

  As shown in FIG. 3, on the lower surface side of the inner lid 30, the first fixing member 31 </ b> A is attached to the plate 34 along the inner peripheral portion near the engaging portion 33 </ b> A of the frame member 32, so that the second fixing The member 31 </ b> B is attached to the plate 34 along the inner peripheral portion of the frame member 32 near the engaging portion 33 </ b> B. A pair of first positioning engagement portions 31C, 31C and a pair of second positioning engagement portions 31D, 31D are disposed on the outer edges of the first fixing member 31A and the second fixing member 31B. The interval between the first positioning engagement portions 31C and 31C in the first fixing member 31A is configured to be smaller than the interval between the second positioning engagement portions 31D and 31D in the second fixing member 31B. This prevents the storage device 80 described later from being erroneously attached to the inner lid 30.

  When the cooked food is cooked with a strong fire, steam and sticky liquid substances and foam substances (hereinafter referred to as blowouts together) are generated from the pan 3 and blown toward the lid 20. Among such blowouts, the liquid substance and the foamy substance are sticky starchy boiled juices, and are said to be “rice balls” when cooking rice. The storage device 80 shown in FIGS. 5 to 7 is attached to the side of the inner lid 30 facing the inside of the pan 3 (that is, the lower surface side), separates the vapor and the liquid material from the blowout, and stores the liquid material. Is to do. The storage device 80 is accommodated in a space formed by the lower surface of the plate 34 and the inner peripheral surface of the seal member 33 in the inner lid 30. The storage device 80 should be cleaned every time after cooking in order to remove the stored liquid substance. Therefore, it is preferable to use a material (for example, stainless steel) in which a sanitary state can be easily maintained in a portion where the liquid substance contacts and stores.

  The storage device 80 includes a substantially annular frame member 82 disposed on the outer peripheral portion thereof, and a plate 84 having a substantially disk shape having a slightly smaller diameter than the outer diameter size of the frame member 82. As shown in FIG. 7, the upper end portion of the plate 84 is fitted into the hole portion of the lower wall portion 82 </ b> A of the frame member 82, and the plate 84 forms a part of the bottom portion of the storage device 80. In the illustrated storage device 80, the bottom surface portion is configured by the lower wall portion 82 </ b> A of the frame member 82 and the plate 84.

  The frame member 82 has a generally annular shape and has an outer peripheral wall portion 85 that rises and extends upward at the outer peripheral portion of the lower wall portion 82A. The outer peripheral wall 85 forms the outer periphery of the storage device 80. A substantially annular upper end rib 87 is formed at the upper end of the outer peripheral wall 85. The upper end rib 87 has an upper end surface 87A. As will be described later, the upper end rib 87 may have a cutout portion 88 in which the upper end surface 87A is partially cut out and is recessed from the upper end surface 87A.

  In FIG. 5, a bulging portion 82 </ b> D that is higher than the lower wall portion 82 </ b> A is formed on the upper portion of the frame member 82. On the outer peripheral portion of the bulging portion 82D, there is disposed an engaging member 83A that is elastically biased radially outward by a spring (not shown) so as to be able to protrude and retract in the radial direction. On the outer peripheral wall 85 located on the opposite side of the bulging portion 82D in the radial direction, an engaging portion 83B protruding outward in the radial direction is disposed. The engaging member 83A of the storage device 80 is engaged with the first positioning engaging portions 31C and 31C in the first fixing member 31A. The engaging portion 83B of the storage device 80 engages with the second positioning engaging portions 31D and 31D in the second fixing member 31B.

  At the center of the lower wall portion 82A, a platform portion 91 having a flat track shape that is higher than the lower wall portion 82A is formed. As shown in FIG. 8, when the storage device 80 is mounted on the inner lid 30, the base 91 faces the flanges 45 and 46 of the first pressure regulating valve 35 and the second pressure regulating valve 36 and the valve seat base plate. Thus, the base 91 is arranged. The height of the bulging portion 82D and the height of the base portion 91 are substantially the same, but are lower than the height of the upper end rib 87. That is, in the frame member 82, the upper end surface 87A of the upper end rib 87 is located at the uppermost position.

  5 and 7, it is surrounded by the inner peripheral surface of the outer peripheral wall portion 85, the upper surface of the lower wall portion 82A, the upper surface of the plate 84, the inner side surface of the bulging portion 82D, and the lower side surface of the base portion 91. The storage space 86 for storing the liquid substance is formed by the space. In the plan view of FIG. 5, the storage space 86 appears to have a plurality of storage chambers due to a slight step portion between the lower wall portion 82 </ b> A and the plate 84. However, since the height of the step portion between the lower wall portion 82A and the plate 84 is low and the respective storage chambers communicate with each other, the stored liquid substance can freely flow in the storage space 86. .

  As shown in FIGS. 5 and 6, in the outermost peripheral portion of the lower wall portion 82A where the lower wall portion 82A and the outer peripheral wall portion 85 intersect, a plurality of reflux holes 89 penetrating the lower wall portion 82A are formed. As shown in FIGS. 5 and 11, guide passages 89 </ b> B are formed on the inner sides in the radial direction of the respective reflux holes 89. The guide passage 89B is configured such that the edge 89A of the lower wall portion 82A in the vicinity of the reflux hole 89 takes a shape that is substantially V-shaped toward the outside in the radial direction. The guide passage 89 </ b> B has a function of collecting and guiding the liquid substance stored in the storage space 86 toward the reflux hole 89.

  The inner lid set 90 in which the storage device 80 is mounted on the inner lid 30 will be described with reference to FIGS.

  As described above, the engaging member 83A and the engaging portion 83B of the storage device 80 engage with the first fixing member 31A and the second fixing member 31B of the inner lid 30, respectively. With the engagement structure, the storage device 80 is detachably attached to the inner lid 30 in the inner lid set 90.

  In the inner lid set 90 in which the storage device 80 is attached to the inner lid 30, there is a certain gap height in the vertical direction between the lid 20 and the storage device 80 and on the outer peripheral wall 85 of the storage device 80. A gap G1 having GH1 is formed. That is, as shown in detail in FIGS. 9 and 10, a gap G <b> 1 is formed between the lower surface 34 </ b> A of the plate 34 and the upper end surface 87 </ b> A that is the upper surface of the upper end rib 87. The gap G <b> 1 is formed in the circumferential direction of the outer peripheral wall portion 85 along the upper end rib 87. The gap height GH1 of the gap G1 allows the passage of steam and liquid substances among the blowouts generated from the pot 3 when a certain cooked food is cooked in the pot 3, but it is a foam-like substance. Are dimensioned to restrict the passage of. When the gap height GH1 of the gap G1 increases, the foamy substance passes through, so that the ability to prevent spillage is reduced. When the gap height GH1 of the gap G1 is reduced, clogging is likely to occur, so that the storage performance of the liquid substance is lowered.

  Although the suitable gap height GH1 depends on the food to be cooked in the pan 3 and the cooking conditions, the suitable gap height GH1 can be determined from the following viewpoints. The gap height GH1 of the gap G1 is a size that does not allow the smallest solid matter to pass through the gap G1 among the cooked food containing various solid matters. For example, consider a case where rice is cooked in a pan 3. In this case, it is also assumed that the rice as a cooked product is a cereal rice containing a cereal having a size smaller than that of the rice (for example, a size of about 3 mm). Therefore, it is preferable that the gap height GH1 of the gap G1 is a size in which small sized grains do not pass through the gap G1. When considering cooking rice such as milled rice, the gap height GH1 of the gap G1 is preferably about 1 mm. As will be described later, when the upper end rib 87 has a notch 88, the gap height GH1 of the gap G1 may be 0 mm, and the storage device 80 may be completely in close contact with the inner lid 30. Therefore, the gap height GH1 of the gap G1 is not limited to the numerical value.

  On the contrary, when the cooked food is made of a large-sized solid, if the gap height GH1 of the gap G1 is made large with reference to the large-sized solid, the foamy substance passes through the gap G1, Spilling is likely to occur. From this viewpoint, the gap height GH1 of the gap G1 is about 3 mm at the maximum. Since the gap height GH1 itself of the gap G1 varies depending on the nature of the foamy substance, it is not limited to this value.

  Before the blowout reaches the gap G1, it needs to pass through a radial gap G0 formed by the inner surface of the seal member 33 and the outer surface of the outer peripheral wall 85. If the radial gap width A of the radial gap G0 is too small, the cooked food and coarse grains softened by cooking enter the gap and close the radial gap G0. Therefore, the radial gap width A of the radial gap G0 is preferably at least 3 mm. If the radial gap width A of the radial gap G0 is too large, the radial size of the storage device 80 becomes small, so that the storage capacity in the storage space 86 decreases. The radial gap width A of the radial gap G0 is preferably 50% or less, and more preferably 5% to 30% with respect to the radius of the storage device 80.

  As shown in FIGS. 5 and 11, the storage device 80 can include a reflux hole 89. The reflux hole 89 is provided to return the liquid material stored in the storage space 86 to the pan 3 as the reflux f. As shown in FIG. 8, a first pressure regulating valve 35 and a second pressure regulating valve 36 each having vent holes 35 </ b> C and 36 </ b> C communicating with a steam path for discharging steam to the outside are disposed in the central portion of the inner lid 30. Yes. When the reflux hole 89 is in the vicinity of the vent holes 35C and 36C formed in the first pressure regulating valve 35 and the second pressure regulating valve 36, the blowout matter is mixed into the steam path through the vent holes 35C and 36C. there is a possibility. In order to prevent this, it is preferable that the reflux hole 89 is disposed on the outer side in the radial direction than the vent hole on the outermost side in the radial direction among the vent holes 35C and 36C. In other words, it is preferable that the reflux hole 89 is not disposed on the radially inner side of the vent holes 35C and 36C that are located on the outermost radial direction. Further, in order to more reliably prevent the blown-out matter from being mixed into the steam path, the reflux hole 89 is formed between the vent hole 35C, 36C, which is the outermost radial direction, between the vent hole and the outer peripheral wall portion 85. It is preferable to be disposed so as to be located on the outer side in the radial direction rather than the half position in the radial direction.

  Next, the flow of blowout in the inner lid set 90 will be described with reference to FIG.

  From the cooking pot, as a blown-out product, steam and sticky liquid substances and foamy substances are generated and rise in the pot 3. The blown-up matter that has risen reaches the radial gap G0 formed by the seal member 33 and the outer peripheral wall 85 as the upward flow F1. Among the blowouts, the vapor and the liquid substance pass through the gap G1 formed between the plate 34 and the upper end rib 87 as the first gap flow F2, but the foamy substance cannot pass through the gap G1. Is removed in the gap G1.

  The vapor and liquid material that have passed through the gap G <b> 1 are stored in the storage space 86 when the liquid material having a large specific gravity falls in the process of passing through the storage space 86. The steam passes through the gap G2 formed between the plate 34 and the base 91 as the second gap flow F3 and reaches the vent hole 35C of the first pressure regulating valve 35. Similarly, the steam passes through the gap G3 formed between the plate 34 and the base 91 as the third gap flow F4 and reaches the vent hole 36C of the second pressure regulating valve 36.

  The steam that has passed through the vent hole 35C of the first pressure regulating valve 35 passes through the communication hole 35G of the first pressure regulating valve 35 as the fourth gap flow F5, and reaches the first pressure regulating valve accommodating portion. Similarly, the steam that has passed through the vent hole 36C of the second pressure regulating valve 36 passes through the communication hole 36G of the second pressure regulating valve 36 as the fifth gap flow F6, and then as the sixth gap flow F7, the second gap flow F6. It passes through the communication hole 36G of the pressure regulating valve 36 and reaches the second pressure regulating valve housing 25. The steam that has passed through the communication holes 35G and 36G flows into a gap formed between the heat radiating plate 24 of the lid 20 and the plate 34 of the inner lid 30. Then, the steam flows into the steam discharge part 29 disposed on the upper plate 21 through the gap, and is then discharged to the outside from the exhaust port formed in the steam discharge part 29.

  Next, a modification will be described with reference to FIGS. The modified example is different from the above-described embodiment in that the protruding portion 93 is formed on the upper end surface 87A of the upper end rib 87.

  In the modification shown in FIGS. 13 and 14, a plurality of projecting portions 93 projecting toward the plate 34 of the inner lid 30 are formed on the upper end surface 87 </ b> A of the upper end rib 87. The protrusion 93 has, for example, a hemispherical shape and a protrusion height GH1. Therefore, when the protrusion 93 contacts the lower surface 34A of the plate 34, a gap height GH1 is formed in the vertical direction. Further, since the two adjacent protrusions 93 are separated from each other, a gap G1 extending in the circumferential direction is formed between them. Even if another cooking item is put into the pack and cooking is performed at the same time as cooking, pack cooking is mistakenly performed, the internal pressure of the pan 3 rises, and the force that presses the storage device 80 against the inner lid 30 works. Since 93 contacts the lower surface 34A of the plate 34, a gap G1 extending in the circumferential direction having a gap height GH1 can be secured.

  Another modification will be described with reference to FIGS. The other modification is different from the above-described embodiment in that the notch 88 is formed in the upper end rib 87.

  In another modification shown in FIGS. 15 and 16, a plurality of cutout portions 88 cut out downward from the upper end surface 87 </ b> A of the upper end rib 87 are formed. The notch 88 has, for example, a rectangular shape and a notch depth of a certain depth. The notch depth can be set to the same size as the gap height GH1, for example. Further, two adjacent notches 88 and 88 are separated from each other, and the distance between the two adjacent notches 88 and 88 is larger than the gap height GH1. Therefore, pack cooking that puts another food in the pack and cooks at the same time as rice cooking is mistakenly performed, the internal pressure of the pan 3 rises, and the force pressing the storage device 80 against the inner lid 30 works. Even if the upper end surface 87A of the upper end rib 87 is in contact with the lower surface 34A of the plate 34, steam and liquid substance can pass through the cutout portion 88 having a certain cutout depth.

  Still another modification will be described with reference to FIGS. The further other modification is different from the other modification described above in that a slit 95 is formed in the upper end rib 87 instead of the notch 88.

  In still another modification shown in FIGS. 17 and 18, a plurality of slit portions 95 that are notched downward from the upper end surface 87 </ b> A of the upper end rib 87 are formed. The slit portion 95 has, for example, an elongated slit shape extending in the vertical direction and has a certain slit depth. The width of the slit portion can be set to the same size as the gap height GH1, for example. The depth of the slit portion 95 is longer than the gap height GH1. Also, the two adjacent slit portions 95 are separated from each other. Therefore, pack cooking that puts another food in the pack and cooks at the same time as rice cooking is mistakenly performed, the internal pressure of the pan 3 rises, and the force pressing the storage device 80 against the inner lid 30 works. Even if the upper end surface 87A of the upper end rib 87 is in contact with the lower surface 34A of the plate 34, the vapor and the liquid substance can pass through the slit portion 95 having a certain slit depth.

  In order to facilitate understanding of the present invention, the description has been made using specific configurations and numbers, but the present invention is not limited to the specific configurations and numbers of the above-described embodiments, Various modifications that can be considered without departing from the scope of the claims can be included. For example, although two pressure regulating valves, the first pressure regulating valve 35 and the first pressure regulating valve 35, are mounted on the inner lid 30, any one of the first pressure regulating valve 35 and the first pressure regulating valve 35 is regulated. Only a configuration in which only the inner lid 30 is mounted may be adopted. Moreover, in the said embodiment, although the pressure rice cooker which cooks rice was mentioned as an example and demonstrated as a heating cooker, it produces boiled juice by raising boiled juice by heating and generating a foamy substance, The present invention can also be applied to a heating cooker that heats and cooks foods other than rice such as jam, boiled beans, and mushrooms boiled in mushrooms.
