Description

  The present invention relates to a cooking device.

  Conventionally, a double-sided grill that can heat both sides of an object to be cooked on a grill is known (see, for example, Patent Document 1). In order to reduce the heating unevenness of the cooking object, it is necessary to increase the distance from the lower burner to the grill net to some extent. Also, if oil drops falling down from the grill net fall directly on the lower burner, problems such as clogging in the flame holes of the burner and burning of the oil drops and generation of oil smoke may occur. The flame holes are arranged, for example, on the lower side of both sides in the grill cabinet, and are arranged so that the flame direction faces the center in the grill cabinet.

It is supported by a substantially L-shaped support member 56 in a state where a gap is left from the bottom surface of the lower housing portion 252. On the upper surface of the lower flame burner 60, a flame hole portion 610, which will be described later, is provided by arranging a large number of flame holes (see FIGS. 3 and 5). The flame hole portion 610 forms a large number of flames upward. The specific structure of the lower fire burner 60 will be described later.

  A grill exhaust unit 70 is provided at the rear of the grill cabinet 25. The grill exhaust unit 70 is formed in a substantially cylindrical shape extending obliquely upward from the rear portion of the grill cabinet 25 to the rear, and communicates with the inside of the grill cabinet 25. A grill exhaust port 71 having a horizontally long and substantially rectangular shape in plan view is provided on the upper portion of the grill exhaust unit 70. The grill exhaust port 71 is disposed immediately below the exhaust port 7 of the top plate 3. The inside of the grill exhaust part 70 is partitioned vertically by an inner wall 72. The inner wall 72 extends obliquely upward from the rear end of the middle plate 40 to a predetermined position below the grill exhaust port 71. An upper duct 74 is provided on the upper side of the inner wall 72. A lower duct 76 is provided below the inner wall 72. The upper duct 74 receives the combustion exhaust from the cooking space 27. The lower duct 76 receives the combustion exhaust from the heating space 28. An upper exhaust port 75 is provided at the downstream end of the upper duct 74 through which combustion exhaust flows. The upper exhaust port 75 discharges the combustion exhaust gas flowing through the upper duct 74 toward the grill exhaust port 71. A lower exhaust port 77 is provided at the downstream end of the lower duct 76 where the combustion exhaust gas flows. The lower exhaust port 77 discharges the combustion exhaust gas flowing through the lower duct 76 toward the grill exhaust port 71. The combustion exhaust discharged from the upper exhaust port 75 and the lower exhaust port 77 is discharged from the grill exhaust port 71 to the outside. A frame trap 65 is installed inside the upper exhaust port 75. The flame trap 65 prevents a flame from coming out from the upper exhaust port 75 in the event that the oil content of the cooking object placed on the cooking pan 10 is ignited.

  The structure of the back side of the cooking space 27 will be described with reference to FIG. In the cooking space 27, a partition wall 30 is provided at a predetermined position slightly in front of the rear end portion of the upper wall portion 251. The partition wall 30 extends downward from a predetermined position of the upper wall portion 251 and is provided across both the left and right sides, and partitions between the cooking space 27 and the upper duct 74. An exhaust opening 301 penetrating in the front-rear direction is provided in a substantially central region excluding the upper side of the partition wall 30. The exhaust opening 301 is formed in a substantially oblong rectangular shape when viewed from the front, and causes the combustion exhaust generated in the cooking space 27 to flow out to the upper duct 74. An opening for fire transfer (not shown) is provided at the upper end of the partition wall 30. The opening for fire transfer is formed in a notch shape downward from the upper end of the partition wall 30, and opens upward toward the lower surface of the upper fire burner 50. An ignition electrode 31 is provided immediately below the upper fire burner 50 and at a position behind the fire transfer opening provided in the partition wall 30. A flame detector 32 is provided at a position on the front side of the opening for fire transfer.

  The ignition electrode 31 ignites a flame hole portion (not shown) for ignition formed by a plurality of flame holes provided on the rear end side of the lower surface of the upper fire burner 50 by generating a spark discharge. The flame detector 32 detects a misfire in a flame detection flame hole (not shown) provided on the rear end side of the lower surface of the upper flame burner 50 and in front of the ignition flame hole. The flame detector 32 only needs to detect any of the heat, light, and electrical characteristics of the combustion flame. For example, the flame detector 32 uses a thermocouple or electrical characteristics to detect heat. For example, a frame rod or an optical sensor classified into three types (ultraviolet type, visible light type, infrared type) depending on the wavelength to be detected can be used. Since both the ignition electrode 31 and the flame detector 32 are disposed on the back side of the grill cabinet 25, the hands are not easily touched from the grill opening 26 of the grill cabinet 25. Moreover, since the sleeve of clothes is hard to be caught by the ignition electrode 31 or the flame detector 32 at the time of cleaning in the grill warehouse 25, workability | operativity at the time of cleaning can also be improved.

  A metal protective cover 35 is provided over the entire area in the left-right direction in the grill box 25 above the exhaust opening 301 on the front surface of the partition wall 30. The protective cover 35 covers and protects the ignition electrode 31 and the flame detector 32 disposed on the back side of the cooking space 27 from the front and the bottom. As a result, the ignition electrode 31 and the flame detector 32 are not exposed in a state of protruding into the grill 25, so that, for example, the clothes sleeve is caught on the ignition electrode 31 or the flame detector 32 when cleaning the grill 25. Can be reliably prevented. In the protective cover 35, a fire transfer opening 36 is provided at a position corresponding to the tip of the ignition electrode 31. As a result, the flame that moves from the ignition flame hole ignited by the ignition electrode 31 to the other flame holes arranged in a substantially straight line in the rear of the protective cover 35 is the opening 36 for the fire transfer. So that the flame holes located in the cooking space 27 are sequentially ignited. Therefore, a flame can be favorably formed in all the flame holes of the upper flame burner 50.

  The structure of the back side of the heating space 28 will be described with reference to FIGS. An ignition electrode 95 and a flame detector 96 are supported by a support member 97 on the left side and the back side of the heating space 28. The ignition electrode 95 ignites a flame hole at a rear end portion of a left flame hole portion 613 described later in the flame hole portion 610 on the lower surface of the lower flame burner 60 by generating a spark discharge. By sequentially igniting other adjacent flame holes by the flame formed in the flame holes, a fire transfer phenomenon occurs, and the entire flame hole portion 610 is ignited. Thereby, since the cooking dish 10 arrange | positioned in the cooking space 27 is heated from the downward direction by the calorie | heat amount from the lower fire burner 60 via the intermediate plate 40, the lower surface of the to-be-cooked object is heated indirectly. . The flame detector 96 is disposed in front of the ignition electrode 95 and detects misfire in the left flame hole 613. The flame detector 96 may be any device that detects any of the heat, light, and electrical characteristics of the combustion flame, similar to the flame detector 32 described above.

  The structure of the lower fire burner 60 will be described with reference to FIGS. As shown in FIG. 5, the lower fire burner 60 includes a main body portion 61, a throat portion 63, a gas inlet 64, and the like. The main body 61 is formed in a substantially rectangular shape that is slightly long in the front-rear direction in plan view. The inside of the main body 61 is hollow, and the internal space is a gas flow path. The throat portion 63 is provided in the right rear portion of the main body portion 61 and is formed in a substantially cylindrical shape extending obliquely rearward to the right. The gas inlet 64 is an opening that is provided at the rear end of the throat portion 63 and expands in a trumpet shape toward the right. A nozzle of a gas amount adjusting device (not shown) is opposed to the gas inlet 64 from the right side. The gas ejected from the nozzle flows into the gas inlet 64 while taking in ambient air. The gas flows through the throat portion 63 while being mixed with air, and flows into the main body portion 61 vigorously.

  On the upper surface of the main body 61, a U-shaped flame hole portion 610 that opens rearward is provided. The flame hole part 610 is formed by arranging a large number of flame holes, and includes a front flame hole part 611, a right flame hole part 612, a left flame hole part 613, and the like. In each flame hole, a flame is formed by igniting the gas supplied from the gas flow path of the main body 61. The front flame hole portion 611 extends in the left-right direction along the front end portion of the main body portion 61. The right flame hole 612 extends substantially linearly rearward from the right end of the front flame hole 611. The left flame hole 613 extends rearward substantially linearly from the left end of the front flame hole 611 and is longer than the right flame hole 612. In a state where the lower fire burner 60 is attached to the lower housing portion 252, the rear end portion of the left flame hole portion 613 is disposed on the back side of the heating space 28 (see FIGS. 3 and 4). The respective leading ends of the ignition electrode 95 and the flame detector 96 are respectively disposed immediately above the rear end of the left flame hole 613.

  When the operation button 13 of the stove 1 (see FIG. 1) is pushed, in the lower fire burner 60, the gas flows into the main body 61 and the ignition electrode 95 is activated in a state where the gas is supplied to the flame hole 610. To do. Due to the spark discharge by the ignition electrode 95, one or more flame holes at the rear end of the left flame hole 613 are first ignited. By the flame formed in each flame hole, each flame hole adjacent in the left flame hole part 613 is ignited one after another. And it ignites in order of the left flame hole part 613, the front flame hole part 611, and the right flame hole part 612, and a flame is favorably formed in all the flame holes of the flame hole part 610 of the lower flame burner 60.

  The flame hole portion 610 is formed in a U-shape in plan view that opens rearward, and the front flame hole portion 611 is located in the front side portion. However, a large amount of combustion space is required on the front side. As described above, the lower fire burner 60 is supported in an inclined state so that the front end side is low and the rear end side is high. Therefore, the front side of the distance between the upper surface of the lower fire burner 60 and the lower surface of the middle plate 40 is wider than the back side. Thereby, even in the heating space 28 in which the distance between the intermediate plate 40 and the lower flame burner 60 is reduced, the gas can be burned well in each flame hole of the flame hole portion 610.

  With reference to FIG. 6, the effective height in the grill cabinet 25 will be described. The effective height L <b> 1 in the grill cabinet 25 is a distance from the convex surface of the bottom surface of the cooking pan 10 having the concave and convex surfaces to the flame hole portion on the lower surface of the upper fire burner 50. The effective height L <b> 2 is an effective height when a flat bottom type cooking dish is used, and is a distance from the bottom surface of the cooking dish to the flame hole on the lower surface of the upper fire burner 50. Note that the height L3 is a distance from the bottom surface of the lower housing portion 252 to the convex surface of the bottom surface having the concave and convex surfaces of the cooking pan 10. The height L4 is a distance from the bottom surface of the lower housing portion 252 to the bottom surface of the flat bottom type cooking dish. The height L5 is a distance from the bottom surface of the lower housing portion 252 to the flame hole portion 610 of the lower fire burner 60. In the grill box 25, the cooking space 27 can be widened by increasing the effective height L1 (L2). In order to increase L1 (L2) in the limited grill 25, it is important to lower the position of the intermediate plate 40 and make the heating space 28 the minimum combustion space necessary for the combustion of the lower fire burner 60. .

  In the grill warehouse 25 of the present embodiment, the middle plate 40 is disposed under the cooking pan 10 on which the food to be cooked is placed, so that a pair attached to both the left and right sides in the lower housing portion 252. The lower fire burner 60 can be arranged in the center portion sandwiched between the rail mechanisms 80. That is, even if oil or the like of the food to be cooked falls from the cooking pan 10, it does not fall into the heating space 28 by the intermediate plate 40, so the lower fire burner 60 can be disposed directly below the cooking pan 10 via the intermediate plate 40. Thereby, since the lower fire burner 60 and the rail mechanism 80 do not overlap with an up-down direction, the height of the heating space 28 can be made lower than before. Further, by adopting a thin plate-like planar burner as the lower fire burner 60, the height of the heating space 28 can be made lower than before. Further, the lower fire burner 60 is disposed in the heating space 28 in an inclined state so that the front end side is low and the rear end side is high. Thus, even in the narrow heating space 28, a wide combustion space in the vicinity of the front flame hole 611 of the flame hole 610 can be ensured, so that the gas combustion performance in the flame hole 610 can be ensured satisfactorily. With such an arrangement relationship, the effective height L1 (L2) in the grill 25 can be made larger than before.

  In addition, since the middle plate 40 is disposed on the upper surface of the lower fire burner 60, oil or the like from the object to be cooked does not fall, so a flame hole portion 610 is provided on the upper surface of the lower fire burner 60. A flame can be formed upward. Thereby, the cooking pan 10 can be efficiently heated via the intermediate plate 40.

  Temporarily, when L3 is adjusted to 61.3 mm (L4 is 53.3 mm when a flat bottom type cooking dish is used) and L5 is 15 to 21 mm, the effective height L1 is 74 mm (a flat bottom type cooking dish is used) In this case, the effective height L2 can be designed to be 82 mm). Therefore, the effective height L1 (L2) in the grill 25 can be increased without increasing the size of the grill 25.

  As described above, the grill device 20 of the stove 1 according to the present embodiment includes the grill cabinet 25. The inside of the grill 25 is divided into a cooking space 27 and a heating space 28 by an intermediate plate 40. In the cooking space 27, an upper fire burner 50 is provided, and a cooking dish 10 for placing an object to be cooked is stored. The heating space 28 is formed by being divided by an intermediate plate 40 below the cooking space 27. A lower fire burner 60 is provided in the heating space 28. The grill device 20 includes an amount of heat from the upper fire burner 50 that is directly given to an object to be cooked, and an amount of heat from the lower fire burner 60 that is indirectly given from the heating space 28 via the intermediate plate 40 and the cooking pan 10. Thus, a so-called indirect heating method is employed in which the object to be cooked on the cooking pan 10 is heated from above and below. Such a grill device 20 includes a tray support frame 17 and a pair of left and right rail mechanisms 80. The dish support frame 17 supports the cooking dish 10 in the cooking space 27. The pair of left and right rail mechanisms 80 are provided on both the left and right sides in the heating space 28, and slide the pan support frame 17 in the front-rear direction. Thereby, the cooking pan 10 can be put in and out through the pan support frame 17 in the grill cabinet 25. The lower fire burner 60 is disposed in the heating space 28 while being sandwiched between the pair of left and right rail mechanisms. That is, the lower fire burner 60 is partitioned from the cooking space 27 by the middle plate 40, and thus can be disposed between the pair of left and right rail mechanisms 80. Thereby, compared with the conventional grilling net system, since the distance from the lower fire burner 60 to the cooking pan 10 can be made small, the effective height L1 (L2) of the grill box 25 can be enlarged.

  In the above description, the dish support frame 17 is an example of the “support means” in the present invention. The pair of left and right rail mechanisms 80 is an example of the “pair of slide moving means” in the present invention.

  In addition, this invention is not limited to the said embodiment, A various change is possible. Although the said embodiment illustrated the stove 1 of the built-in type, a table stove may be sufficient. Moreover, although the stove 1 incorporates the grill apparatus 20, the heating cooker comprised only by the grill apparatus 20 may be sufficient.

  The lower-burner burner 60 in the above embodiment is a thin plate-like planar burner, but other types of burners may be used. For example, a burner in which the direction of the flame is directed to the center in the grill 25 may be used. Good. Moreover, although the shape of the flame hole part 610 is a substantially U shape opened toward back, you may make it other shapes. The position and arrangement of the flame holes may be different from those in the above embodiment.
