  In the rice cookers of Patent Literatures 1 and 2, the passage portion through which the steam and the liquid material pass has a cylindrical shape, so there is a limit in securing the volume of the passage portion. Therefore, there is a disadvantage that the liquid material easily flows out from the passage portion to the outlet side in the steam passage.

  This invention makes it a subject to provide the cooker which can suppress the outflow of the liquid substance to the exit side in a steam channel effectively.

  The present invention includes a cooking pan, a lid that covers the opening of the cooking pan, and a steam passage that is provided on the lid and that discharges the steam in the cooking pan to the outside of the lid. On the outlet side in the passage is formed a tray part for storing the liquid material flowing out together with steam from the cooking pan, the tray part protrudes upward from the bottom wall of the tray part, A cooker comprising a cylindrical passage portion whose bottom wall side communicates with an inlet side in the steam passage, and the passage portion includes an outer peripheral wall having a horizontally long cross-sectional shape in a direction intersecting the axis of the passage portion. I will provide a.

  In this cooker, since the horizontally long passage portion is formed in the receiving plate portion, it is easy to secure the volume of the passage portion. For example, the volume in the outer peripheral wall can be made larger than that of the conventional passage portion by setting the dimension in the short direction of the passage portion to be the same as the diameter of the conventional cylindrical passage portion. Therefore, the outflow of the liquid material from the passage portion to the tray portion can be suppressed. In addition, the liquid material flows back into the cooking pan when the steam exhaust pressure decreases. As a result, since the liquid material can be prevented from overflowing in the tray portion, the tray portion can be reduced in size.

  The lid body may include a lid body disposed on the cooking pan side, and the saucer portion including the passage portion may be formed integrally with the lid body.

  Here, as in Patent Document 2, in the case where the steam passage is provided with a detachable steam port set, not only the tray part is a separate body, but also a packing needs to be disposed at a portion where the steam port set of the lid is mounted. There is. On the other hand, in this aspect, since the tray part is formed integrally with the lid body, the structure for preventing spillage can be provided in the steam passage without increasing the number of parts. Moreover, since the area which the saucer part in a cover main body occupies can be reduced by the horizontally long channel | path part which enlarged the volume, the area for arrange | positioning a heater in a cover main body can be ensured.

  The steam passage includes a detachable cap that closes an upper end opening of the tray portion, and the passage portion has an upper wall that covers an upper end of the outer peripheral wall, and is positioned on one end side in the short direction of the outer peripheral wall. A plurality of outflow holes are formed in the outer peripheral wall or the upper wall at intervals along the longitudinal direction of the outer peripheral wall, and the cap has a side opposite to the outflow direction of the steam from the outflow hole. An exhaust hole may be formed on the surface.

  According to this aspect, since the plurality of outflow holes are formed in the outer peripheral wall along the longitudinal direction, the total opening area is increased by the number of outflow holes, and the steam is easily discharged from the passage portion to the tray portion. Further, the steam flows out in one direction into the saucer part, turns inside the saucer part, and flows toward the exhaust hole formed on the side opposite to the outflow direction. Therefore, the path length for separating the liquid material from the vapor can be secured in the tray portion.

  The passage portion may be arranged at an interval from the center of the saucer portion in the short direction of the outer peripheral wall so that the outflow hole approaches the inner peripheral surface of the saucer portion.

  According to this aspect, the liquid material that has flowed out together with the steam from the passage portion can be reliably attached to the inner peripheral surface of the tray portion, and the separation of the steam and the liquid material can be promoted.

  The lid includes an inner lid that closes the opening of the cooking pan, and the inner lid is formed with a communication hole that communicates with the steam passage, and the opening area of the communication hole is determined by the passage portion. It may be set to be wider than the total opening area of the outflow holes.

  According to this aspect, since the total opening area of the outflow hole of the passage portion is narrower than the total opening area of the communication hole of the inner lid, the flow rate of the steam flowing out from the outflow hole into the tray portion can be increased. Therefore, the liquid substance which flowed out with the steam from the passage part can be attached to the inner peripheral surface of the dish part, and the separation of the steam and the liquid substance can be promoted.

  A first rib extending from the passage portion to an inner peripheral surface of the saucer portion is formed on the saucer portion, and a second rib located above the first rib is formed on the cap, A slit for allowing vapor to pass therethrough may be formed between the first rib and the second rib.

  According to this aspect, since the flow path in the tray portion is partially blocked by the first rib and the second rib, the liquid material is attached to the first rib or the second rib, and the vapor and the liquid material are separated. Can be promoted. The first rib and the second rib are dimensioned so that a slit is formed between them. That is, since the second rib does not interfere with the first rib, the workability of attaching the cap to the tray portion can be improved.

  In the cooking device of the present invention, since the horizontally long passage portion is formed in the tray portion, the volume in the passage portion can be easily secured. Therefore, the outflow of the liquid material from the passage portion to the tray portion can be suppressed.

(First embodiment)

  1 to 6 show a rice cooker 10 according to a first embodiment of the present invention. As shown in FIG.1 and FIG.2, the rice cooker 10 is the rice cooker main body 15 by which the rice cooker (cooking pan) 12 was arrange | positioned so that attachment or detachment was possible, and the cover body 20 attached to the rice cooker main body 15 so that opening and closing was possible. Is provided. The lid body 20 includes a steam passage 33 for discharging steam generated in the rice cooking pot 12 to the outside of the lid body 20. In the present invention, the “oneba”, which is a viscous liquid material, is prevented from flowing out to the outlet side 33 b in the steam passage 33. In addition, below, it demonstrates on the basis of the state which closed the cover body 20 with respect to the rice cooker main body 15. FIG.

(Outline of rice cooker)
As shown in FIG.1 and FIG.2, the rice cooker main body 15 is provided with the accommodating part 16 which accommodates the rice cooking pot 12, and the heating part 17 which heats the rice cooking pot 12. As shown in FIG. The rice cooking pot 12 is heated by controlling the heating unit 17 by the microcomputer, and the rice set in the rice cooking pot 12 is cooked. As the heating unit 17, a heating plate incorporating a heater disposed at the bottom of the housing unit 16 is used, but an induction heating coil (see FIG. 7) disposed on the outer periphery of the housing unit 16 may be used.

  The lid 20 covers the opening 13 of the rice cooker 12 and is rotatably attached to the hinge connecting portion 18 on the back side of the rice cooker body 15. The lid 20 includes a lid main body 22 disposed on the rice cooking pot 12 side, a lid cover 26 that covers the outside of the lid main body 22, and an inner lid 30 that is detachably disposed on the lid main body 22. Among them, the lid main body 22 is provided with a metal heat radiating plate 23 at a portion facing the rice cooking pot 12, and a lid heater 24 is disposed on the upper surface of the heat radiating plate 23. The inner lid 30 closes the opening 13 of the rice cooker 12 and includes a seal member 31 that is in close contact with the inner peripheral surface of the opening 13.

  Referring also to FIG. 3, the steam passage 33 includes a communication hole 34 formed in the inner lid 30, a communication portion 37 formed in the upper portion of the inner lid 30, and an exhaust portion formed in the upper portion of the communication portion 37. 40. Among them, the communication part 37 is composed of a space surrounded by the inner lid 30, the packing 36, and the bottom wall 43 of the exhaust part 40. Specifically, the heat radiating plate 23 is provided with an opening 35 for exposing the bottom wall 43 of the exhaust part 40. An annular packing 36 is disposed on the lid body 22. The packing 36 seals between the periphery of the opening 35 of the heat radiating plate 23 and the lid main body 22, and seals between the inner lid 30 and the lid main body 22 through the opening 35. Further, the exhaust part 40 includes a tray part 42 and a cap 55 which will be described in detail later.

  The steam generated in the rice cooking pot 12 by heating passes through the communication hole 34 that is the inlet of the steam passage 33, the communication part 37, and the exhaust part 40 in this order, and the exhaust hole of the exhaust part 40 that is the outlet of the steam passage 33. From 57, it is discharged to the outside of the lid 20. At this time, the liquid material flows out from the rice cooking pot 12 into the steam passage 33 together with the steam. In order to prevent the liquid material from flowing out of the lid 20 through the exhaust hole 57, an exhaust unit 40 having a devised overall structure is provided as described below.

(Outline of exhaust section)
As shown in FIGS. 3 and 4, the exhaust part 40 includes a tray part 42 formed integrally with the lid body 22 and a cap 55 that closes the upper end opening of the tray part 42. Further, the tray portion 42 includes a cylindrical passage portion 48 that communicates with the communication portion 37 on the inlet side 33 a in the steam passage 33.

  The tray portion 42 stores liquid material separated from the steam, and includes a circular bottom wall 43 and a cylindrical outer wall 44 protruding from the outer peripheral portion of the bottom wall 43. An annular packing 45 is disposed at the upper end of the outer wall 44.

  The passage portion 48 includes a cylindrical outer peripheral wall 49 that protrudes upward from the bottom wall 43. The opening 50 at the lower end of the outer peripheral wall 49 opens so as to face the communication portion 37. The upper end of the outer peripheral wall 49 is covered with the upper wall 51. An outflow hole 52 is provided at a ridge that is a boundary portion between the outer peripheral wall 49 and the upper wall 51.

  The cap 55 is a generally rectangular plate disposed in the recess 27 of the lid cover 26. An insertion portion 56 that protrudes in a cylindrical shape is formed on the lower surface of the cap 55. The insertion portion 56 is inserted into the tray portion 42 through the insertion hole 28 formed in the lid cover 26, and is hermetically and liquid-tightly sealed by the packing 45. A horizontally long exhaust hole 57 is formed in the approximate center of the cap 55.

  The steam flows into the passage portion 48 from the communication portion 37 and flows into the tray portion 42 from the outflow hole 52 of the passage portion 48. In the saucer part 42, the liquid material that has flowed out together with the vapor adheres to the inner peripheral surface of the outer wall 44 of the saucer part 42. Thereby, the vapor and the liquid material are separated, and only the vapor is discharged from the exhaust hole 57 of the cap 55 to the outside.

  Here, when making the exhaust part 40 into the removable steam port set, it is necessary to arrange packing not only for the saucer part to be a separate body but also on the part of the lid where the steam port set is mounted. However, in this embodiment, since the saucer part 42 for storing a liquid substance is integrally formed in the lid main body 22, a separate saucer part and packing are unnecessary. Therefore, the number of parts for configuring the rice cooker 10 can be reduced as compared with the case where the exhaust part 40 is a detachable steam port set.

(Volume of passage part and saucer part)
In the following description, the front-rear direction (the left-right direction in FIG. 1) of the rice cooker 10 is referred to as the X direction, the width direction of the rice cooker 10 (the direction perpendicular to the paper in FIG. 1) is referred to as the Y direction, The vertical direction (the vertical direction in FIG. 1) is sometimes referred to as the Z direction.

  As shown in FIGS. 3 and 5, in the passage portion 48, the axis A extends in the vertical direction (Z direction) with the lid 20 closed with respect to the rice cooker body 15. The total height T of the passage portion 48 from the bottom wall 43 to the top wall 51 is set as high as possible without interfering with the cap 55. Thereby, the workability | operativity at the time of attaching the cap 55 to the saucer part 42 is improved.

  Moreover, the volume V2 which can store the liquid substance of the saucer part 42 is enlarged by setting the total height T of the channel | path part 48 as high as possible. Specifically, the portion of the tray portion 42 that can store the liquid material is below the outflow hole 52 of the passage portion 48. That is, when the liquid level of the liquid material in the tray portion 42 exceeds the outflow hole 52 of the passage portion 48, the exhaust pressure from the inside of the cooking pan 12 decreases, so that the liquid material flows backward from the tray portion 42 to the passage portion 48. It is to do. Therefore, the volume V2 of the saucer portion 42 can be increased by increasing the overall height T of the passage portion 48 and securing the distance from the bottom wall 43 of the saucer portion 42 to the outflow hole 52.

  The outer peripheral wall 49 of the passage portion 48 is formed in a rectangular tube shape in which the cross-sectional shape in the direction orthogonal to the axis A of the passage portion 48 is horizontally long. Specifically, the outer peripheral wall 49 includes a pair of long side surfaces 49a and 49b extending substantially along the YZ plane, and a pair of short side surfaces 49c and 49d extending generally along the XZ plane. The dimension L1 from one end (short side surface 49c) in the longitudinal direction (Y direction) of the outer peripheral wall 49 to the other end (short side surface 49d) is from one end (long side surface 49a) in the short direction (X direction) of the outer peripheral wall 49. It is set to be longer than the dimension L2 to the other end (long side surface 49b).

  The volume V1 in the passage portion 48 is defined by the overall height T of the passage portion 48, the dimension L1 of the long side surfaces 49a and 49b, and the dimension L2 of the short side surfaces 49c and 49d. When the volume V1 of the passage portion 48 is small, even a small amount of liquid material immediately flows out from the outflow hole 52 into the tray portion 42, so that the tray portion 42 is immediately filled with the liquid material. Therefore, in order to reduce the outflow amount of the liquid material from the outflow hole 52 into the tray portion 42, it is preferable to increase the volume V1 of the passage portion 48 as much as possible.

  However, if the diameter R of the tray portion 42 is constant and the dimension (volume V1) in the lateral direction (X direction and / or Y direction) of the passage portion 48 is increased, the volume V2 of the tray portion 42 is decreased. In this case, even if a small amount of liquid material has flowed out of the outflow hole 52 into the tray portion 42, the tray portion 42 is immediately filled with the liquid material. In addition, when the volume V2 of the tray portion 42 is secured while the volume V1 of the passage portion 48 is increased, the diameter (area of the bottom wall 43) of the tray portion 42 is increased, so that the opening 35 of the heat sink 23 is also increased. Thus, the space for arranging the lid heater 24 cannot be secured.

  That is, in order to achieve both the suppression of the outflow of the liquid material from the passage portion 48 to the tray portion 42 and the suppression of the overflow of the liquid material in the tray portion 42, the volume V1 of the passage portion 48 and the tray portion 42 It is not preferable that the volume V2 is too small or too large. Moreover, in order to ensure the arrangement space of the lid | cover heater 24, it is preferable to make the area of the bottom wall 43 of the saucer part 42 as narrow as possible even if it is the same volume V2.

Therefore, the volume V2 of the saucer part 42 is set to 70 cm ³ or more that can accommodate a liquid substance (foamed rice cake) that flows out when a large amount of water is put into the rice cooker 12 at the time of full rice cooking. In this embodiment, it is set to 226 cm ³ . Incidentally, the volume of the saucer part of the conventional rice cooker provided with a cylindrical channel | path part is 270 cm < ³ >. Moreover, it is preferable to set the diameter R of the saucer part 42 to 40% or less with respect to the diameter of the heat sink 23, and is set to 45% (for example, 80 mm) in this embodiment.

On the other hand, the volume V1 of the passage portion 48 is preferably set to a range of 10% or more and 20% or less with respect to the volume V2 of the tray portion 42, and is set to 12% (for example, 28 cm ³ ) in this embodiment. doing.

  The dimension L2 of the short side surfaces 49c and 49d of the passage portion 48 is preferably set to 13.5 mm or more so that a finger can be put into the passage portion 48 and cleaned, and is set to 17 mm in this embodiment. Incidentally, the diameter of the conventional cylindrical passage portion is also set to 14 mm or more so that the finger can be put in and cleaned. Further, the ratio of the dimension L2 of the short side surfaces 49c, 49d to the diameter R of the tray portion 42 is preferably set in the range of 15% to 25%, and is set to 22% in this embodiment.

  The ratio of the dimension L1 of the long side surfaces 49a and 49b to the diameter R of the saucer portion 42 is preferably set in the range of 45% to 55%, and is set to 53% in this embodiment.

  Thus, since the horizontally long passage portion 48 is formed in the tray portion 42, it is easy to secure the volume V1 of the passage portion 48. That is, by setting the dimension in the short direction (X direction) of the passage portion 48 to be the same as the diameter of the conventional cylindrical passage portion, the volume can be made larger than that of the conventional passage portion. Therefore, the outflow of the liquid material having a specific gravity larger than that of the steam from the passage portion 48 to the tray portion 42 can be suppressed. As a result, since the liquid material can be prevented from overflowing in the tray portion 42, the tray portion 42 can be reduced in size. Thereby, since the area which the saucer part 42 in the lid | cover main body 22 occupies can be decreased, the area for arrange | positioning the lid | cover heater 24 in the lid | cover main body 22 is securable.

  The liquid material remaining in one space composed of the communication portion 37 and the passage portion 48 without flowing out into the saucer portion 42 flows back into the rice cooker 12 due to a decrease in the exhaust pressure of the steam. Further, since the communication part 37 is surrounded by the packing 36, the liquid material does not overflow in a part other than the communication part 37 of the inner lid 30.

(Details of passage)
As shown in FIGS. 3 to 5, the outflow hole 52 of the passage portion 48 is located on the front side (one end side in the short direction (X direction)) of the rice cooker 10, and the long side surface 49 a of the outer peripheral wall 49. And formed at the ridge of the upper wall 51. A plurality (three in this embodiment) of the outflow holes 52 are provided in the longitudinal direction (Y direction) of the passage portion 48 at a predetermined interval. Thereby, it is comprised so that the vapor | steam containing a liquid material may flow out to one direction with respect to the saucer part 42. FIG.

  As shown most clearly in FIG. 5, the passage portion 48 extends from the center O of the tray portion 42 in the short direction of the outer peripheral wall 49 so that the outflow hole 52 approaches the inner peripheral surface of the outer wall 44 of the tray portion 42. It is arranged at intervals in the direction in which steam in the (X direction) flows out.

  As shown in FIGS. 3 and 6, the exhaust hole 57 of the cap 55 is formed on the side opposite to the direction in which the steam flows out from the outflow hole 52. Further, the exhaust hole 57 is formed in an oval shape extending in the Y direction similarly to the passage portion 48.

  In this manner, since the plurality of outflow holes 52 are formed in the passage portion 48, the total opening area is increased by the number of the outflow holes 52, and the steam is easily discharged from the passage portion 48 to the tray portion 42. Further, the steam flows out into the tray part 42 in one direction, turns inside the tray part 42, and flows toward the exhaust hole 57 formed on the side opposite to the steam outlet direction. Therefore, the path length for separating the liquid material from the steam can be secured in the tray portion 42.

  Further, since the passage portion 48 is formed with respect to the tray portion 42 so that the outflow hole 52 approaches the inner peripheral surface of the outer wall 44 of the tray portion 42, the liquid material that has flowed out of the passage portion 48 is received by the receiving portion 42. It can be reliably attached to the inner peripheral surface of the outer wall 44. Therefore, separation of the vapor and the liquid material can be promoted, and only the vapor can be reliably discharged from the exhaust hole 57 to the outside.

(Outflow hole opening area)
As shown in FIGS. 3 and 5, three outflow holes 52 are provided in the passage portion 48, and as shown in FIG. 2, five communication holes 34 are provided in the inner lid 30. Referring to FIG. 3, the communication hole 34 is formed so that the position in the X direction coincides with the axis A of the passage portion 48 and is spaced in the Y direction so as to be located immediately below the passage portion 48.

  The opening area of each outflow hole 52 is set to be larger than the opening area of each communication hole 34. The communication hole 34 of the inner lid 30 is formed with a diameter smaller than the grain size of the cooked rice so that the cooked rice in the rice cooker 12 is not clogged. The outflow hole 52 of the passage portion 48 is formed with an opening area that is larger than the opening area of the communication hole 34 and is not blocked by the liquid material.

  On the other hand, the total opening area of all the outflow holes 52 is set to be smaller than the total opening area of all the communication holes 34. In the entire steam passage 33, the cross-sectional area (opening area) is increased in the order of the outlet portion 52, the communication hole 34, the exhaust hole 57, the passage portion 48, the communication portion 37, and the tray portion 42 including the cap 55. .

  As described above, since the total opening area of the outflow hole 52 of the passage portion 48 is narrower than the total opening area of the communication hole 34 of the inner lid 30, steam and liquid material flowing out from the outflow hole 52 into the tray portion 42. Can speed up. Therefore, the liquid material flowing out from the passage portion 48 can be attached to the inner peripheral surface of the outer wall 44 of the tray portion 42. As a result, separation of the vapor and the liquid material can be promoted, and only the vapor can be reliably discharged from the exhaust hole 57 to the outside.

(Flow path in exhaust section)
As shown in FIG. 3, in the exhaust part 40, a first space into which steam flows in from the outflow hole 52 by a first rib 53 provided in the tray part 42 and a second rib 58 provided in the cap 55. 62 and a second space 63 for discharging the steam from the exhaust hole 57. As a result, the separation of the vapor and the liquid material flowing into the tray part 42 is promoted.

  As shown in FIGS. 3 and 5, the first rib 53 protrudes upward from the bottom wall 43 of the tray part 42, and the inner peripheral surface of the outer wall 44 of the tray part 42 from the end in the Y direction of the passage part 48. It is the plate body extended over. The first rib 53 is inclined so as to spread outward (Y direction) from the passage portion 48 toward the front side in the X direction, that is, toward the outflow direction of the steam from the outflow hole 52.

  As shown in FIGS. 3 and 6, the second rib 58 protrudes downward from the cap 55 so as to be positioned upward along the first rib 53, and from the inner peripheral surface of the insertion portion 56 to the insertion portion 56. It is the plate body which protrudes toward the center. The second ribs 58 are located at a predetermined interval with respect to the first ribs 53. In addition, the inner end 58 a of the second rib 58 in the radial direction of the insertion portion 56 is located at a predetermined interval with respect to the outer peripheral wall 49 of the passage portion 48.

  As shown most clearly in FIG. 3, slits 60 a having a predetermined interval are formed between the second rib 58 and the first rib 53. In addition, slits 60 b having a predetermined interval are formed between the second rib 58 and the passage portion 48. These slits 60a and 60b constitute a passage for allowing vapor to pass therethrough and communicate with each other. The total opening area of the slits 60 a and 60 b is larger than the total opening area of the outflow hole 52.

  As described above, the interior of the exhaust part 40 is partially closed between the first space 62 and the second space 63 by the first rib 53 and the second rib 58. Therefore, when the vapor and the liquid material flow into the second space 63 from the first space 62, the liquid material is attached to the first rib 53 or the second rib 58, and the separation of the vapor and the liquid material can be promoted.

  The second rib 58 is set so that the slit 60 a is formed between the second rib 58 and the first rib 53, and the slit 60 b is also formed between the second rib 58 and the passage portion 48. Therefore, when the cap 55 is attached to the tray portion 42, the second rib 58 does not interfere with the first rib 53 or the passage portion 48. As a result, the workability of attaching the cap 55 to the tray part 42 can be improved.

  The liquid material separated by adhering to the inner peripheral surface of the exhaust part 40 or the ribs 53 and 58 is temporarily stored in the tray part 42. When the pressure in the communication portion 37 decreases due to the absence of water in the rice cooker 12, it passes through the reflux holes 46 provided at the bases on both sides in the X direction of the passage portion 48 and is refluxed into the communication portion 37. 34 is returned to the cooking pot 12. The bottom wall 43 in which the reflux hole 46 is formed is inclined so that the part in which the reflux hole 46 (passage portion 48) is formed is the lowest end. Further, the total opening area of the two reflux holes 46 is smaller than the total opening area of the outflow hole 52 of the passage portion 48.

(Second Embodiment)
FIG.7 and FIG.8 shows the rice cooker 10 of 2nd Embodiment. The second embodiment is different from the first embodiment in that the exhaust portion 40 of the steam passage 33 formed in the lid body 20 is configured by a separate exhaust hole set that can be attached to and detached from the lid body 20. .

  The exhaust unit 40 includes a tray part 42 that is separate from the lid body 22, and a cap 55 that closes the upper end opening of the tray part 42. As in the first embodiment, a passage portion 48 including a square cylindrical outer peripheral wall 49 is formed in the tray portion 42. Further, a rectangular tubular connecting portion 65 communicating with the inside of the outer peripheral wall 49 is provided on the bottom wall 43 of the tray portion 42 so as to protrude downward.

  The lid cover 26 of the lid 20 is formed with a recess 27 for arranging the exhaust part 40. The recess 27 is formed with an insertion hole 28 through which the connection portion 65 can be inserted.
