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 gridiron is known (see, for example, Patent Document 1). In order to reduce uneven heating of the food to be cooked, it is necessary to increase the distance from the lower heat burner to the gridiron to some extent. Also, if the oil droplets that fall down from the grill fall directly onto the lower heat burner, problems such as clogging the flame holes of the burner or burning the oil droplets and generating oil smoke may occur. The flame hole portion is arranged, for example, on the lower side of both sides in the grill chamber, and is arranged so that the direction of the flame faces the center in the grill chamber.

Japanese Unexamined Patent Publication No. 2011-83628

However, since there is also a need for a space inside the grill to install a rail mechanism for sliding the grill plate and grid toward you, the position of the lower heat burner is, for example, about 30 mm from the bottom of the grill. It had to be above the height of. Therefore, it was difficult to increase the effective height from the gridiron to the top heat burner in the grill.

An object of the present invention is to provide a cooking device capable of increasing the effective height in the grill.

The cooker according to claim 1 is provided with a cooking space in which a top heat burner is provided and a cooking plate for placing an object to be cooked is stored, and a bottom heat burner is provided in the grill chamber. It has a heating space formed by partitioning it with a middle plate on the lower side, and the amount of heat from the upper heat burner directly given to the object to be cooked and the middle plate and the cooking dish from the heating space. The cooking dish is cooked in a heating cooker that employs an indirect heating method that heats the object to be cooked on the cooking dish from both the upper and lower sides by the amount of heat indirectly given from the lower heat burner. A support means for supporting in a space and a pair of slide moving means provided on both left and right sides in the heating space to slide the support means in the front-rear direction are provided, and the lower heat burner is the same in the heating space. The lower fire burner is formed in a plate shape while being sandwiched between a pair of slide moving means, and a plurality of flame holes forming an upward flame are provided on the upper surface thereof, and the plurality of flame holes are provided. It is characterized in that it is arranged at a height position between the upper part and the lower part of the pair of slide moving means .

In addition to the configuration of the invention according to claim 1, the cooker according to claim 2 has the lower heat burner formed in a plate shape extending in the front-rear and left-right sides in the grill, and the plurality of flame holes are formed. , At least on the left and right sides of the upper surface of the lower flame burner.

The heating cooker according to claim 1 is an indirect heating method, and a cooking dish can be taken in and out in the front-rear direction via a support means by a pair of slide moving means provided in the heating space. Since the lower heat burner is provided in the heating space and is separated from the cooking space by a middle plate, the lower heat burner can be provided while being sandwiched between the pair of slide moving means. As a result, the distance from the lower heat burner to the cooking plate can be reduced as compared with the conventional grid method, so that the effective height of the grill can be increased.

Further , since the lower heat burner has a plate shape and can be made thinner than the conventional one, such a lower heat burner can be easily provided while being sandwiched between the pair of slide moving means. In the indirect heating method, the cooking plate and the lower heat burner are separated by a middle plate, so that the oil does not fall downward from the cooking plate. Therefore, since a plurality of flame holes provided on the upper surface of the lower heat burner can be arranged directly under the middle plate, the cooking dish can be efficiently heated via the middle plate.

On the upper surface of the lower fire 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 heat burner 60 will be described later.

A grill exhaust section 70 is provided at the rear of the grill chamber 25. The grill exhaust portion 70 is formed in a substantially cylindrical shape extending diagonally upward from the rear portion of the grill storage 25 to the rear, and communicates with the inside of the grill storage 25. A grill exhaust port 71 having a substantially rectangular shape in a horizontally long plan view is provided on the upper portion of the grill exhaust portion 70. The grill exhaust port 71 is arranged directly below the exhaust port 7 of the top plate 3. The inside of the grill exhaust portion 70 is vertically partitioned by an inner wall 72. The inner wall 72 extends diagonally 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 on the lower side of 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 on the downstream side through which the 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 on the downstream side through which the combustion exhaust 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 gas discharged from the upper exhaust port 75 and the lower exhaust port 77, respectively, is discharged to the outside from the grill exhaust port 71. Further, a frame trap 65 is installed inside the upper exhaust port 75. The frame trap 65 prevents the flame from being emitted from the upper exhaust port 75 in the unlikely event that the oil content or the like of the food to be cooked placed on the cooking dish 10 ignites.

The structure of the inner 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 on both the left and right sides to partition 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 rectangular shape horizontally long when viewed from the front, and the combustion exhaust generated in the cooking space 27 is discharged to the upper duct 74. A fire transfer opening (not shown) is provided at the upper end of the partition wall 30. The fire transfer opening 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 at a position directly below the upper fire burner 50 and 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 fire transfer opening.

By generating a spark discharge, the ignition electrode 31 ignites an ignition flame hole portion (not shown) formed by aggregating a plurality of flame holes provided on the rear end side of the lower surface of the upper flame burner 50. The flame detector 32 detects a misfire in the flame detection flame hole portion (not shown) provided on the rear end side of the lower surface of the upper fire burner 50 and on the front side of the ignition flame hole portion. The flame detector 32 may be any as long as it detects any of the heat, light, and electrical characteristics of the combustion flame. For example, the flame detector 32 uses a thermocouple or an electrical characteristic to detect heat. As the frame rod, an optical sensor classified into, for example, three types (ultraviolet ray type, visible light type, infrared type) according to the detection wavelength can be used. Since the ignition electrode 31 and the flame detector 32 are both arranged on the back side of the grill storage 25, they are not easily touched by the grill opening 26 of the grill storage 25. Further, when cleaning the inside of the grill 25, for example, the sleeves of clothes are less likely to be caught by the ignition electrode 31 or the flame detector 32, so that workability during cleaning can be improved.

A metal protective cover 35 is provided on the upper side of the exhaust opening 301 on the front surface of the partition wall 30 over the entire area in the grill chamber 25 in the left-right direction. The protective cover 35 covers and protects the ignition electrode 31 and the flame detector 32 arranged 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 protruding state in the grill chamber 25. Therefore, when cleaning the inside of the grill chamber 25, for example, the sleeve of clothes is caught by the ignition electrode 31 or the flame detector 32. Can be reliably prevented. Further, in the protective cover 35, a fire transfer opening 36 is provided at a position corresponding to the tip end portion of the ignition electrode 31. As a result, the flame transferred from the ignition flame hole ignited by the ignition electrode 31 to the other flame holes arranged substantially linearly in front of the protective cover 35 is the fire transfer opening 36. Is possible, so that the flame holes located in the cooking space 27 are sequentially ignited. Therefore, flames can be satisfactorily formed in all the flame holes of the upper flame burner 50.

The structure of the inner side of the heating space 28 will be described with reference to FIGS. 4 and 5. The ignition electrode 95 and the flame detector 96 are supported by the support member 97 on the left side and the back side of the heating space 28. When the ignition electrode 95 generates a spark discharge, the flame hole at the rear end of the left flame hole portion 613, which will be described later, is ignited in the flame hole portion 610 on the lower surface of the lower flame burner 60. By sequentially igniting other adjacent flame holes by the flame formed in the flame hole, a fire transfer phenomenon occurs, and the entire flame hole portion 610 is ignited. As a result, the cooking plate 10 arranged in the cooking space 27 is heated from below by the amount of heat from the lower heat burner 60 via the middle plate 40, so that the lower side surface of the object to be cooked is indirectly heated. .. The flame detector 96 is arranged in front of the ignition electrode 95 and detects a misfire in the left flame hole portion 613. The flame detector 96 may detect any of the heat, light, and electrical characteristics of the combustion flame, similarly to the flame detector 32 described above.

The structure of the lower heat burner 60 will be described with reference to FIGS. 3 to 6. As shown in FIG. 5, the lower heat burner 60 includes a main body portion 61, a throat portion 63, a gas inflow port 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 a plan view. The inside of the main body 61 is hollow, and the internal space thereof is a gas flow path. The throat portion 63 is provided on the right rear portion of the main body portion 61, and is formed in a substantially cylindrical shape extending diagonally rearward to the right. The gas inlet 64 is an opening provided at the rear end of the throat portion 63 and expanding in diameter toward the right in a trumpet shape. At the gas inflow port 64, nozzles of a gas amount adjusting device (not shown) are arranged facing each other from the right side. The gas ejected from the nozzle flows into the gas inlet 64 while taking in the surrounding air. The gas flows through the throat portion 63 while being mixed with air, and vigorously flows into the inside of the main body portion 61.

On the upper surface of the main body 61, a U-shaped flame hole portion 610 in a plan view that opens toward the rear is provided. The flame hole portion 610 is formed by arranging a large number of flame holes, and includes a front flame hole portion 611, a right flame hole portion 612, a left flame hole portion 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 portion 612 extends substantially linearly rearward from the right end portion of the front flame hole portion 611. The left flame hole portion 613 extends rearward in a substantially straight line from the left end portion of the front flame hole portion 611, and is longer than the right flame hole portion 612. When 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 arranged on the inner side of the heating space 28 (see FIGS. 3 and 4). The tip portions of the ignition electrode 95 and the flame detector 96 are respectively arranged directly above the rear end portion of the left flame hole portion 613.

When the operation button 13 (see FIG. 1) of the stove 1 is pushed in, in the lower heat burner 60, the ignition electrode 95 operates in a state where gas flows into the main body 61 and gas is supplied to the flame hole 610. do. The spark discharge by the ignition electrode 95 first ignites one or more flame holes at the rear end of the left flame hole portion 613. The flames formed in the flame holes ignite the adjacent flame holes one after another in the left flame hole portion 613. Then, the left flame hole portion 613, the front flame hole portion 611, and the right flame hole portion 612 are ignited in this order, and flames are satisfactorily formed in all the flame holes of the flame hole portion 610 of the lower flame burner 60.

The flame hole portion 610 is formed in a U-shape in a plan view that opens toward the rear, and the front flame hole portion 611 is located on the front side portion. Therefore, in the heating space 28 of the grill chamber 25, from the back side. However, a lot 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 distance between the upper surface of the lower heat burner 60 and the lower surface of the middle plate 40 is wider on the front side than on the back side. As a result, even in the heating space 28 in which the distance between the middle plate 40 and the lower heat burner 60 is narrowed, the gas can be satisfactorily burned in each flame hole of the flame hole portion 610.

The effective height in the grill chamber 25 will be described with reference to FIG. The effective height L1 in the grill chamber 25 is the distance from the convex surface of the bottom surface of the cooking dish 10 having the uneven surface to the flame hole portion on the lower surface of the upper fire burner 50. The effective height L2 is an effective height when a flat-bottomed cooking dish is used, and is a distance from the bottom surface of the cooking dish to the flame hole portion on the lower surface of the upper fire burner 50. The height L3 is the distance from the bottom surface of the lower housing portion 252 to the convex surface of the bottom surface having the uneven surface of the cooking dish 10. The height L4 is the 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 the distance from the bottom surface of the lower housing portion 252 to the flame hole portion 610 of the lower fire burner 60. By increasing the effective height L1 (L2) in the grill 25, the cooking space 27 can be widened. In order to increase L1 (L2) in the limited grill chamber 25, it is important to lower the position of the middle plate 40 and make the heating space 28 the minimum combustion space required for combustion of the lower heat burner 60. ..

In the grill chamber 25 of the present embodiment, since the middle plate 40 is arranged under the cooking plate 10 on which the food to be cooked is placed, a pair attached to both left and right sides in the lower housing portion 252. The lower heat burner 60 can be arranged in the central portion sandwiched between the rail mechanisms 80 of the above. That is, even if the oil or the like of the object to be cooked falls from the cooking plate 10, the middle plate 40 does not drop into the heating space 28, so that the lower heat burner 60 can be arranged directly under the cooking plate 10 via the middle plate 40. As a result, the lower heat burner 60 and the rail mechanism 80 do not overlap in the vertical direction, so that the height of the heating space 28 can be made lower than before. Further, by adopting a thin plate-shaped flat burner as the lower heat burner 60, the height of the heating space 28 can be further lowered as compared with the conventional case. Further, the lower fire burner 60 is arranged in the heating space 28 in a state of being inclined so that the front end side is low and the rear end side is high. As a result, even in a narrow heating space 28, a wide combustion space can be secured in the vicinity of the front flame hole portion 611 of the flame hole portion 610, so that the combustion performance of the gas in the flame hole portion 610 can be satisfactorily secured. Due to such an arrangement relationship, the effective height L1 (L2) in the grill chamber 25 can be made larger than before.

Further, since the middle plate 40 is arranged on the upper surface of the lower heat burner 60 so that oil or the like from the object to be cooked does not fall, a flame hole portion 610 is provided on the upper surface of the lower heat burner 60 in each flame hole. A flame can be formed upwards. As a result, the cooking plate 10 can be efficiently heated via the middle plate 40.

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

As described above, the grill device 20 of the stove 1 of the present embodiment includes a grill storage 25. The inside of the grill 25 is divided into a cooking space 27 and a heating space 28 by a middle plate 40. In the cooking space 27, a top heat burner 50 is provided, and a cooking plate 10 for placing an object to be cooked is stored. The heating space 28 is formed by partitioning the cooking space 27 under the cooking space 27 with a middle plate 40. A lower heat burner 60 is provided in the heating space 28. The grill device 20 has the amount of heat from the upper heat burner 50 directly given to the object to be cooked and the amount of heat from the lower heat burner 60 indirectly given from the heating space 28 via the middle plate 40 and the cooking plate 10. Therefore, a so-called indirect heating method is adopted in which the object to be cooked on the cooking plate 10 is heated from both the upper and lower sides. Such a grill device 20 includes a dish support frame 17 and a pair of left and right rail mechanisms 80. The plate support frame 17 supports the cooking plate 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 dish support frame 17 in the front-rear direction. As a result, the cooking plate 10 can be taken in and out of the grill storage 25 via the plate support frame 17. The lower fire burner 60 is arranged in the heating space 28 while being sandwiched between the pair of left and right rail mechanisms. That is, since the lower heat burner 60 is separated from the cooking space 27 by the middle plate 40, it can be arranged while being sandwiched between the pair of left and right rail mechanisms 80. As a result, the distance from the lower heat burner 60 to the cooking plate 10 can be reduced as compared with the conventional grid method, so that the effective height L1 (L2) of the grill storage 25 can be increased.

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

The present invention is not limited to the above embodiment, and various modifications can be made. Although the above embodiment illustrates the built-in type stove 1, it may be a table stove. Further, although the stove 1 has a built-in grill device 20, it may be a cooking device composed of only the grill device 20.

The lower fire burner 60 of the above embodiment is a thin plate-shaped flat burner, but other types of burners may be used. For example, a burner having the flame directed toward the center of the grill 25 may be used. good. Further, the shape of the flame hole portion 610 is a substantially U-shape that opens toward the rear, but other shapes may be used. The position and arrangement of the flame holes may be different from those in the above embodiment.

In the grill device 20 of the above embodiment, the ignition electrode 95 and the flame detector 96 are provided on the inner side of the grill chamber 25, but the ignition electrode 95 and the flame detector 96 do not have to be on the inner side as long as they are inside the grill chamber 25.

Instead of the cooking dish 10 of the above embodiment, for example, a gridiron or a flat plate may be supported by the dish support frame 17.
