DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-sided heating type grill apparatus in which burners are installed above and below a grill storage.

[0002]

2. Description of the Related Art A grill apparatus provided in a gas stove includes a grill storage having an opening / closing door on the front side and an exhaust port provided on a rear ceiling. Inside the grill storage, a water pan on which a grill is placed is housed so as to be freely taken in and out. In the double-sided heating type grill, a lower fire burner is installed at the bottom of the grill storage, an upper fire burner is installed at the ceiling, and a fire transfer burner (pilot burner) is provided between both burners. It has been proposed to provide a pair of lower fire burners at the lower portion of both side walls of the grill storage as this lower fire burner, and to provide a fire transfer burner between the lower fire burners in order to perform a fire transfer between the two lower fire burners. I have.

[0003] The lower fire burner and the upper fire burner can be adjusted in heat power by two independent operation pieces, and the heat power can be changed in a range of strong to weak, and both burners can be selectively extinguished. It is desirable to be able to perform the desired cooking. In this configuration, there is a method in which the fire transfer burner is an emergency fire pilot burner to which gas is supplied in conjunction with a lower fire burner.

[0004]

However, when the emergency fire pilot burner is linked to the supply of gas to the lower fire burner, it is necessary to extinguish the lower fire burner during the combustion of both the upper fire burner and the lower fire burner. Combustion conditions change significantly. This has a negative effect on the stable combustion of the upper fire burner,
There are drawbacks that cause harmful emissions. This phenomenon is particularly remarkable when the upper fire burner is a ceramic burner. Also,
When starting the combustion of the lower fire burner,
There is also the disadvantage that it takes time. SUMMARY OF THE INVENTION It is an object of the present invention to provide a gas stove grill having a pair of lower burner and upper fire burner, in which the lower fire burner can be ignited and extinguished reliably and promptly, thereby achieving stable combustion of the upper fire burner and purification of exhaust gas. Is to provide a grill device that can achieve the above.

[0005]

According to the present invention, there is provided a grill apparatus comprising: a grill storage; a pair of lower fire burners provided on both lower sides of the grill storage; an upper fire burner mounted on a ceiling of the grill storage; A first normal-fire pilot burner for transferring a fire between the lower-fire burner and the upper-fire burner; and a continuous crater that is horizontally installed at the bottom and lower part of the grill chamber and transfers the fire between the pair of lower-fire burners. A second normal-fire pilot burner, an ignition device, and a first operation piece and a second operation piece that adjust the thermal power of the pair of lower-fire burners and the upper-fire burner from a maximum thermal power to a minimum thermal power and a fire extinguishing position, respectively. .

[0006]

According to the present invention, since the second normal-fire pilot burner for transferring the fire between the pair of lower-fire burners is provided, the lower-fire burner can be ignited immediately when the lower-fire burner returns to combustion from extinguishing. Also use both upper and lower fire burners,
In the case of so-called double-sided firing, even if only the lower fire is extinguished, the second pilot fire burner does not extinguish, but burns at the continuous crater of the second pilot fire burner installed horizontally at the back of the grill storage. Therefore, even when the upper burner burner is switched from the state of burning with both the upper burner and the lower burner, the combustion gas does not flow only to the upper burner but to the second pilot burner. , The combustion condition of the upper fire burner can be prevented from greatly changing. Therefore, stable combustion of the upper fire burner of the grill and purification of exhaust gas can be achieved. According to the second aspect of the present invention, since the second ignition device is provided in the combustion plate type ceramic burner, in which the flame spreads slowly at the time of ignition, ignition delay of the upper fire burner can be effectively prevented.

[0007]

FIG. 1 shows a grill apparatus 1 for a gas stove according to an embodiment of the present invention. The grill device 1 includes a grill storage 2 having an access port 21 on the front surface and an exhaust port at the rear of the ceiling. The grill warehouse 2 includes a pair of left and right lower fire burners 3 and 3 installed horizontally at the lower portions on both sides, an upper fire burner 4 installed almost horizontally at the center of the ceiling of the grill warehouse 2, A first normal-fire pilot burner 5 with a continuous crater, which is attached to the lower part in the vertical direction and ignites one lower-fire burner 3 and one upper-fire burner 4 and performs a mutual fire, and a grill storage 2 A grill burner, which is horizontally installed at the back and is composed of a pair of left and right lower fire burners 3 and a second normal fire pilot burner 6 with a continuous crater that performs a mutual fire transfer, is mounted. Reference numeral 7 denotes a thermal power control device, which controls the ignition, fire extinguishing, and thermal power control of the grill burner by operating an operating means 8 installed on the front of the gas stove.

The thermal power control device 7 has a safety valve 71, a main valve 72, and a governor 73 interposed on the upstream side of the gas supply passage 11. The gas supply path 11 downstream of the governor 73 is
Branches to a first branch 12 to the lower fire burners 3 and 3, a second branch 13 to the upper fire burner 4, a branch 14 to the first pilot pilot burner 5, and to a second pilot pilot burner 6. The branch path 15 of FIG. The first normal-fire pilot burner 5 is provided with a first sparker (ignition device) 51 for performing ignition.

In this embodiment, the upper fire burner 4 is a ceramic burner provided with a ceramic plate as shown in FIG. 2, has an annular combustion surface 41 on the lower surface, and is fixed to the lower surface of the ceiling plate 22 of the grill storage 2. Have been. 23 is an exhaust port of the grill. The ceramic plate is held by the outer pressing plate 42 and the inner pressing plate 43, and the second sparker 44 is connected to the ground electrode 45 having the outer pressing plate 42 extending inward.
Are mounted so as to form a spark discharge gap therebetween. The inner and outer pressing plates 42 and 43 have a flame-holding strip formed by bending a rising wall toward the combustion surface 41 side.

[0010] The second sparker 44 is mounted at the combustion surface 4
1, and the first pilot flame burner 5 is mounted behind the combustion surface 41. As a result, as compared with the case where only the first normal-fire pilot burner 5 is used, the ignition of the ceramic burner whose flame propagation is slow is performed smoothly, and even when an ignition error occurs due to one of the ignition devices, the other is used. There is an advantage that ignition can be performed by an ignition device. The rear side and the left and right sides of the rear combustion surface 411 where the flame from the upper end of the first normal fire pilot burner 5 hits are surrounded by the surrounding wall 46. Accordingly, even if a flow to the exhaust port 23 occurs in the grill storage, the flame from the first normal-fire pilot burner 5 does not easily become unstable, and a reliable fire transfer to the upper-fire burner 4 becomes possible. The surrounding wall 46 may be used as a ground electrode of the second sparker 44.

In the first branch 12 and the second branch 13, the gas flow rate is gradually changed from a maximum heating power (maximum valve opening) to a minimum heating power (minimum valve opening), and combustion is stopped (valve closing). Throttle valves V1 and V2 which can be operated are provided. The operating means 8 includes a point fire extinguishing device 81 serving as a switch for opening and closing the safety valve 71 and the main valve 72 to generate a discharge spark in the first sparker 51 and the second sparker 44, and a lower fire burner 3, 3. A first lever (operation piece) 82 for adjusting the heating power, a second lever (operation piece) 83 for adjusting the heating power of the upper fire burner 4,
An alternative fire extinguishing mechanism 84 in which only one of the lever 82 and the second lever 83 is alternatively set to the fire extinguishing position.

The operation of the gas stove grill will be described. When the point fire extinguishing device 81 is pressed, the main valve 72 and the safety valve 71 are opened and fuel gas is supplied to the burners 3 to 6 via the governor 73. At the same time, sparks from the sparkers 51 and 44 cause the first normal fire pilot burner 5 and the upper The fire burner 4 is ignited. The second normal-fire pilot burner 6 and the upper-fire burner 4 are ignited by the flame of the first normal-fire pilot burner 5, and the lower-fire burners 3, 3 are ignited by the second normal-fire pilot burner 6. If the first lever 82 or the second lever 83 is set to the left end position (fire extinguishing), the upper fire burner 4 or the lower fire burner 3 corresponding to the lever at the left end position does not ignite, but the first lever 82 , Second
Regardless of the position of the lever 83, the first normal fire pilot burner 5 and the second pilot burner 6 are always ignited. When the position of the first lever 82 and / or the second lever 83 is adjusted after this ignition operation, the lower fire burners 3, 3 and / or the upper fire burner 4 burn with a desired heating power according to the purpose of cooking. .

When any one of the lower fire burners 3 and 3 or the upper fire burner 4 is stopped from burning, one of the first lever 82 and the second lever 83 is set to the left end position. When one of the first lever 82 and the second lever 83 is set to the combustion stop position (the leftmost position), the alternative fire extinguishing mechanism 84 stops the other one of the first lever 82 and the second lever 83 to stop the combustion. The position (leftmost position) is prevented by the obstruction side 841. Thus, the inexplicable state in which the point fire extinguishing device 81 remains in the ignition position despite the fact that both the first lever 82 and the second lever 83 are in the combustion stop position does not occur, and the upper fire burner in the fire extinguishing state does not occur. 4 or lower fire burner 3 is the first pilot fire burner 5
And, the ignition state can be set by the second normal-fire pilot burner 6. In the above embodiment, the sparker is shown as the ignition device. However, an instantaneous pilot burner may be provided as the ignition device, and the flame of this instantaneous pilot burner may be directed to the first normal-fire pilot burner 5. Moreover,
This flame may be directed to the first normal-fire pilot burner 5 and the lower-fire burner 3.
