The gist is that it was used for secondary air for combustion of burners . In the grill of the present invention having the above-described structure, the grill pan is efficiently cooled by the air flowing through the cooling air passage forcedly blown by the motor fan when the grill is used. As a result, the grill dish is cooled below a certain temperature (for example, below the ignition temperature of fish oil or the like), and there is no need to fill the grill dish with water. [0007] In the grill of the present invention having the above-described structure, hot air in which the heat of the grill dish is absorbed by the secondary air for combustion of the grill burner is used. As a result, the degree of sealing in the grill storage can be increased, and the temperature in the grill storage can be increased. [0008] In order to further clarify the structure and operation of the grill of the present invention described above, a preferred embodiment will be described below with reference to the drawings. In the embodiment, the present invention is applied to a grill of a gas table with a grill. In the first embodiment shown in FIGS. 1 to 3, reference numeral 1 denotes a grill storage, and a motor fan is provided at the bottom thereof. When the motor fan MF is provided with a cooling air passage 2 forcibly blown by the MF,
The air taken in from the air inlet 3 at the front end is sucked by the motor fan MF, passes through the cooling air passage 2, passes from the suction port 4 of the motor fan MF to the suction chamber 5 and the exhaust port 7.
The exhaust gas in the grill chamber 1 is discharged to the outside together with the exhaust gas from the exhaust port 7. The motor fan MF is configured so that the fan F provided in the suction chamber 5 is rotated by a motor M installed outside the device. The motor M is connected so as to be turned on and off in conjunction with the operation of a power supply and an operation knob described later. Reference numeral 8 denotes a grill pan, which is slidably provided on the upper surface of the cooling air passage 2 of the grill cabinet 1 so that it can linearly advance and retreat along a guide rail 9 so that it can be taken in and out. A radiation fin 10 is provided on the lower surface of the bottom of the grill pan 8, and when the grill pan 8 is stored in a predetermined position of the grill cabinet 1, the radiation fin 10 faces the cooling air passage 2 and air flowing through the cooling air passage 2. With grill plate 8
And the grill plate 8 is heated to a certain temperature or lower (for example,
(Below the ignition temperature of fish oil etc.). Note that, as the heat radiation fins 10, a plate-like fin shown in FIG. 3 is used in addition to the cylindrical fin shown in FIG. The motor fan MF is driven only when the grill is used by turning on and off an energizing circuit to the motor M in conjunction with the operation knob of the grill. For example,
When the thermocouple 12 is driven to rotate by the output of the thermocouple 12 heated by the grill burner 11, the thermocouple 12 has a voltage of 1.5 V / 3.
It is preferable to use a thermocouple integrated body that can obtain an output of about 0 mA. Further, as another rotation driving means, for example, a dry battery power supply (not shown) may be used in addition to a storage battery power supply in which an electromotive force of a thermocouple heated by the grill burner 11 is stored. Reference numeral 13 in the figure denotes a front door of the grill, which is integrally connected to the grill plate 8. 14 is a grill,
It is removably mounted on the grill plate 8. Reference numeral 15 denotes a hot plate, which is heated by the grill burner 11 and uses the radiant heat to bake and cook an object 16 such as a fish placed on the grill 14. 17 is a lid of the exhaust port 7 and 18 is a grill storage 1
The exhaust path, 19, is the virtue of the stove. In the above configuration, when using the grill, when the operation knob is ignited and the grill burner 11 is ignited, the power supply circuit to the motor fan MF is also turned on. Therefore, when the motor fan MF is driven to rotate by the output of the thermocouple 12, the grill a is ignited and the thermocouple 12 is heated by the flame a at the same time. M is driven to rotate the fan F. Therefore, the air forcedly blown by the motor fan MF flows through the cooling air passage 2, and the heat of the grill plate 8 is efficiently absorbed by the air through the radiating fins 10, and the grill plate 8 is, for example, fish oil or the like. Cool below the ignition temperature of. [0015] Incidentally, as a power source for rotating the motor fan MF, when using a battery or batteries are <br/> charge reservoir by a thermocouple heated by Gurirubana 11, Gurirubana the operation knob and the ignition operation 11 At the same time, the energizing circuit for the motor fan MF is turned on to drive the motor M of the motor fan MF to rotate the fan F, thereby cooling the grill pan 8 according to the above-described reason. Next, a second embodiment shown in FIGS. 4 and 8 is provided with the grill pan cooling means of the first embodiment. The hot air (air after cooling the grill pan) that has absorbed the heat of the above is used as it is. That is, an air supply duct 20 extending laterally from the discharge passage 6 on the downstream side of the suction chamber 5 is disposed below the grill burner 11, and a number of air ejection holes 21 formed in the air supply duct 20 are provided. The hot air is blown out of the grill burner 11 and supplied to the combustion secondary air of the grill burner 11. The air supply duct 20 has a square or circular cross section, for example.
Then, as shown in FIG. 4, a simple jet hole is formed in the air supply duct 20 as the air jet hole 21,
As shown in FIG. 5, a nozzle pipe for air ejection is provided in the air supply duct 20 so that the secondary air for combustion is uniformly supplied to the flame a of each part of the grill burner 11. . In the second embodiment, the other structure and the cooling action of the grill pan are the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and description thereof is omitted. In the above configuration, the warm air (air after cooling the grill pan) that has absorbed the heat of the grill pan 8 reaches the air supply duct 20 from the suction chamber 5 via the discharge path 6, and the air in the air supply duct 20. The grill burner 1 blows out from the blowout hole 21.
1 for the secondary air for combustion. Therefore, the secondary air for combustion of the grill burner 11 is not directly introduced from the outside air, and the air after cooling the grill pan is effectively used as it is. Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. . According to the above-described grill of the present invention, the grill pan is efficiently cooled to a certain temperature or less by the cooling air forcedly blown by the motor fan when the grill is used.
