Description

  The present invention relates to a grill cooking appliance capable of performing oven cooking in a grill cabinet provided with an upper fire burner and a lower fire burner.

  The grill cooker is used for grill cooking. Grill cooking is a cooking method in which the food to be cooked is irradiated with radiant heat from a heat source provided in the upper part of the food to the food to be cooked stored in the grill. Such grill cooking includes, for example, grilled fish. Since only the upper surface of the object to be cooked can be heated only by the radiant heat from the upper heat source, it is necessary to heat the upper surface and turn the object to be cooked and heat the lower surface. Therefore, there is a heat source that is also installed below the object to be cooked so that it can be heated from below simultaneously with heating from above. As such a grill cooking utensil, there is a grill cooking utensil alone, or a grill cooking utensil incorporated in a table stove and provided with an upper fire burner and a lower fire burner as upper and lower heat sources (see, for example, Patent Document 1).

  On the other hand, oven cooking is a cooking method in which the temperature inside the chamber in which the object is stored is heated from about 200 ° C. to about 300 ° C., and the entire object is heated in a high temperature atmosphere in the chamber. It is. Examples of such oven cooking include baking for baking dough, and cooking for baking gratin, pizza, and the like.

Japanese Patent No. 3748061 (paragraph 0016)

  Both grill cooking and oven cooking are common in that the food to be cooked is put in the cabinet and the food to be cooked is heated. However, grill cooking is heated by radiant heat from the upper heat source, so if you try to cook oven with a grill cooking utensil, the top surface of the cooked food will burn and cook well before the whole cooked food is heated. Can not.

  In the grill cooking appliance described in the above-mentioned patent document 1, since the heating power of the upper fire burner and the lower fire burner is adjusted by one gas cock, two systems each supply gas to both burners from this one gas cock. The pipe line is extended. Therefore, if a separate solenoid valve is added to the pipe for supplying gas to the upper fire burner, and the upper fire burner is extinguished and only the lower fire burner is burned, oven cooking can be performed in the grill.

  However, when the solenoid valve is added in this way, the cost of the solenoid valve is directly passed on to the product cost, resulting in a problem that the price of the product increases. In addition, it is necessary to secure a space for installing the solenoid valve, and the solenoid valve cannot be added depending on the model.

  Then, this invention makes it a subject to provide the grill cooking appliance which extinguishes an upper fire burner and enables oven cooking by a lower fire burner, without adding a solenoid valve separately in view of said problem.

In order to solve the above-mentioned problems, a grill cooking utensil according to the present invention includes an upper-fired burner and a lower-fired burner in a grill warehouse for storing an object to be cooked. In the grill cooker having a gas cock, a fixed plate having a plurality of openings and a rotating plate having a plurality of openings are provided in the one gas cock, and a part of the plurality of openings formed in the rotating plate. Is communicated with the upper fire burner, the remaining opening is communicated with the lower fire burner, and the rotating plate is rotated with the rotating plate in contact with the fixing plate, thereby matching the opening of the rotating plate. The gas is supplied to the upper fire burner and the lower fire burner through the above-mentioned part, and the opening communicated with the upper fire burner is closed with a rotating plate and communicated with the lower fire burner. Open the above rotating plate Provided with a function to burn only subsided burner to extinguish the upper flame burners by matching the opening, by burning only subsided burner to raise the temperature in the grill chamber by the function of the gas cock, the grill An oven cooking function for performing oven cooking in a refrigerator is provided, and the heating power of the lower fire burner can be increased or decreased while the upper fire burner is extinguished.

  Rather than adding a separate solenoid valve, the cost for adding this function is reduced as much as possible by providing a function to extinguish the upper fire burner and burn only the lower fire burner in one gas cock. In addition, the increase in space is suppressed as much as possible.

  As can be seen from the above description, the present invention can be oven-cooked with a grill cooking utensil, so that the use of the grill cooking utensil can be increased.

The figure which shows the structure of one embodiment of this invention Conceptual diagram showing the structure of the grill warehouse Appearance of cock Cross section of thermal power control unit The figure which shows the structure of a rotating plate and a fixed plate The figure which shows the other structure of a rotating plate and a fixed plate

  Referring to FIG. 1, reference numeral 1 denotes a gas stove provided with a grill cabinet 2 which is a grill cooking appliance according to the present invention. A grill cabinet 2 that opens to the front surface of the gas stove 1 is provided. As shown in FIG. 2, an upper fire burner 21 is provided in the ceiling portion of the grill cabinet 2, and a pair of lower fire burners 22 are provided at the lower portions of the left and right side surfaces. 3 is a juice receiving tray, and a grill net 31 is detachably connected to the upper part. When an object to be cooked such as fish is placed on the grill 31 and the upper fire burner 21 is ignited, the upper surface of the object to be cooked is heated by the radiant heat from the upper fire burner 21. Moreover, the flame extended from the lower flame burner 22 goes under the grill net 31, and heats the lower surface of a to-be-cooked object. Thus, grill cooking is performed by heating with the upper fire burner 21 and the lower fire burner 22.

  The gas supply amount to the upper fire burner 21 and the lower fire burner 22 is controlled by the gas cock 4 shown in FIG. On the upper surface of the gas cock 4, there are provided a discharge port 41 for supplying gas to the upper fire burner 21 and a discharge port 42 for supplying gas to the lower fire burner 22. Increase or decrease the amount. 51 is a stepping motor.

  Referring to FIG. 4, a cam 52 rotated by a stepping motor 51 is provided, and when this cam 52 rotates, an electromagnetic safety valve 53 is opened, and gas passes through the electromagnetic safety valve 53 from the right side in the figure. Flows to the left. The heating power adjusting unit 5 is provided with a rotating plate 6 that is rotated by a stepping motor 51 and a fixed plate 7 that is always fixed. The rotation plate 6 and the fixed plate 7 are each provided with an opening to be described later. Depending on the rotation phase of the rotation plate 6, the opening of the rotation plate 6 and the opening of the fixed plate 7 may coincide with each other. In the state where both openings coincide, gas flows from the opening of the rotating plate 6 through the opening of the fixed plate 7 to the discharge ports 41, 42. However, in the state where both openings do not coincide, the gas flows upward from the rotating plate 6. There is no. Reference numeral 54 denotes a rubber packing, and an orifice plate 55 is attached to the upper surface of the packing 54 for accurately defining the flow rate for each gas type.

  Referring to FIG. 5, the rotating plate 6 is formed with a longitudinal opening 61 and a circular opening 62 in the circumferential direction. On the other hand, the fixed plate 7 is provided with six openings 71 to 76. These six openings 71 to 76 are arranged on the same circumference, and the openings 71, 73, 74, and 76 are formed with a small diameter, and the openings 72 and 75 are formed with a large diameter. In the figure, the gas that has passed through the openings 71, 72, 73 located in the right half is supplied to the lower fire burner 22, and the gas that has passed through the openings 74, 75, 76 located in the left half is supplied to the upper fire burner 21. The For example, regarding the thermal power of the lower fire burner 22, the amount of gas passing through one of the small opening 71 or the opening 73 corresponds to a low fire state of the lower fire burner 22. The amount of gas passing through the large opening 72 corresponds to the strong fire of the lower fire burner 22. If the opening 72 overlaps with the opening 61 and a gas corresponding to a strong fire passes through, the heating power becomes a strong fire regardless of whether or not the other openings 71 and 73 overlap the opening 61.

  In the position P0 shown in FIG. 5, since the openings 61 and 62 of the rotating plate 6 do not overlap any of the openings 71 to 76 of the fixed plate 7, no gas is supplied to the upper fire burner 21 and the lower fire burner 22, The fire is extinguished.

  When the rotating plate 6 is rotated rightward in the drawing to reach the position P1, the opening 61 of the rotating plate 6 overlaps the opening 71 of the fixed plate 7. Then, a gas corresponding to low heat passes only through the opening 71. The gas is supplied to the lower fire burner 22 as described above, and the heating power is low. In this state, the upper fire burner 21 remains in the fire extinguishing state.

  When the rotating plate 6 further rotates to the position P2, the opening 61 overlaps the openings 71, 72, 73. The gas that has passed through these openings 71, 72, 73 is supplied to the lower fire burner 22. In addition, since the opening 72 overlaps with the opening 61, a gas amount sufficient for a strong fire state is supplied to the lower fire burner 22. The upper fire burner 21 remains in the fire extinguishing state.

  At the position P3, the opening 61 overlaps the openings 71 to 73 and the opening 74. A gas corresponding to a strong fire is supplied to the lower fire burner 22 as in the position P2, and a gas corresponding to a low fire passing through the opening 74 is supplied to the upper fire burner 21.

  At the position P4, a gas corresponding to a strong fire that has passed through the openings 72 and 73 is supplied to the lower fire burner 22. On the other hand, a gas corresponding to a strong fire that has passed through the openings 74 and 75 is supplied to the upper fire burner 21.

  In the position P5, the gas that has passed only through the opening 73 is supplied to the lower fire burner 22, so that the lower fire burner 22 is in a low fire state. On the other hand, the upper fire burner 21 is in a high fire state because the gas that has passed through the openings 74, 75, and 76 is supplied.

  In the position P6, since the opening 62 of the rotating plate overlaps the opening 71 with respect to the lower fire burner 22, the gas corresponding to the low heat passing through the opening 71 is supplied. On the other hand, the upper fire burner 21 is supplied with a gas corresponding to a low fire passing through only the opening 76.

  And if it returns to the position P0, since the gas is not supplied to the upper fire burner 21 and the lower fire burner 22 as mentioned above, it will be in a fire extinguishing state. Although not shown, a main valve, which is an electromagnetic on-off valve, is attached upstream of the gas cock 4, and after cooking, the position becomes P0 and the main valve closes so that the upper fire burner 21 and The state where no gas is supplied to the lower fire burner 22 is secured.

  As described above, at the positions P1 and P2, the upper fire burner 21 is extinguished and the lower fire burner 22 is ignited. In this state, the inside of the grill cabinet 2 is warmed by the flame of the lower fire burner 22, but the radiant heat from the upper fire burner 21 is not generated. Therefore, if the grill 31 is removed from the soup pan 3 and a gratin plate is placed on the soup pan 3 instead, the gratin can be cooked by oven cooking.

  On the other hand, in the positions P3 to P6, since the upper fire burner 21 is ignited, it is possible to perform grill cooking by applying radiant heat to the cooking object on the grill 31 from above. Although not shown in the drawing, a normal fire ignition burner straddling the upper fire burner 21 and the lower fire burner 22 is provided, and even if the upper fire burner 21 and the lower fire burner 22 are extinguished once during the position movement, etc. If the gas is supplied again, it is ignited with a heating power corresponding to the supply amount of the gas.

  The shapes of the rotating plate 6 and the fixed plate 7 are not limited to those shown in FIG. For example, referring to FIG. 6, three openings 61, 62, 63 may be provided in the rotating plate 6, and five openings 71 to 75 may be provided in the fixed plate 7. The openings 71 and 74 are both small and provided on the same circumference. The remaining openings 72, 73, 75 are both large and provided on the same circumference. At the position P0, the gas is not supplied to the upper fire burner 21 and the lower fire burner 22 as in the embodiment shown in FIG.

  When the rotating plate 6 is rotated rightward in the drawing to reach the position P1, the opening 61 of the rotating plate 6 overlaps the opening 71 of the fixed plate 7. Therefore, a gas corresponding to a low fire is supplied to the lower fire burner 22. Note that no gas is supplied to the upper fire burner 21 and the fire is extinguished.

  When the rotating plate 6 is turned to the right to the position P2, the opening 62 overlaps the opening 75 with respect to the lower fire burner 22, so that the lower fire burner 22 is in a high fire state. The upper fire burner 21 is still in the fire extinguishing state.

  At the position P3, a gas corresponding to a low fire passing through only the opening 71 is supplied to the lower fire burner 22. On the other hand, the upper fire burner 21 is supplied with a gas corresponding to a low fire passing through the opening 74.

  At the position P4, the gas corresponding to the high fire is supplied to the lower fire burner 22 because the opening 62 overlaps the opening 72. On the other hand, the upper fire burner 21 remains in a state where a gas corresponding to a low fire passing through the opening 74 is supplied.

  In the position P5, the gas corresponding to the high fire is supplied to the lower fire burner 22 because the opening 63 overlaps the opening 75. Further, since the opening 62 overlaps the opening 73 with respect to the upper fire burner 21, the gas corresponding to the strong fire is also supplied.

  At the position P6, the lower fire burner 22 is supplied with a gas corresponding to a low fire that has passed through only the opening 71. On the other hand, the upper fire burner 21 is supplied with a gas corresponding to a strong fire that has passed through the opening 73.

  5 is suitable for a gas cock in which a relatively large fixed plate 7 can be provided, and the number of openings formed in the rotating plate 6 can be reduced. Moreover, in the structure shown in FIG. 6, since the fixed plate 7 can be made comparatively small, a gas cock can be made compact.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
