Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a gas burner ignition device, and more particularly to a gas burner ignition device in which a battery, an igniter as an ignition mechanism, and the like are arranged in a case to make the whole compact.

[0002]

[Prior art]

 Conventionally, as a device of this type, although not particularly shown, a piezoelectric element is attached to the original cock provided in the case, and a high voltage generated by applying pressure to the piezoelectric element by pressing and rotating the operation knob is generated. Generally, a structure in which a spark is discharged to ignite a gas was used.

[0003]

[Problems to be solved by the device]

 By the way, in the conventional device, since the ignition operation is a one-time ignition operation, there are many ignition mistakes. Not only will raw gas be emitted if an ignition mistake is made, but depending on the ignition timing delay, there will be a spark around the rod burner. Since it was ignited with the gas filled, it was extremely dangerous because it could cause an explosion and burns.

The present invention has been made in view of such conventional problems, and an object thereof is to make the entire device compact and to ensure reliable ignition without any misfiring. It is an object of the present invention to provide an extremely safe gas burner ignition device that can be used with peace of mind without the risk of filling or burns.

[0005]

[Means for solving problems]

 For this purpose, the present invention provides a main cock having an operating knob on the outside and a gas inlet from the main burner on the inside, and a main burner connected to the main cock and connected to the main cock. A battery, a micro switch electrically connected to the battery, an igniter electrically connected to the micro switch and the battery, an igniter electrically connected to the battery, in a case in which a branch pipe having a gas outlet is arranged. It is characterized in that a spark plug that is connected and ignites a pilot burner by emitting a spark by the pressing and rotating operation of the operation knob is arranged.

【Example】

 An embodiment will be described with reference to the drawings together with the operation thereof. FIG. 1 is a plan view of an example of an ignition device according to the present invention, and FIG. 2 is a side view thereof. In these drawings, a case 1 has a substantially box shape with an upper opening, and both side plates thereof are partially cut away. There is. An operation knob 2 is provided on the outside of the face plate of the case 1 so as to be connected to an original cock 3 arranged at a substantially central portion inside the case 1. The operation knob 2 pushes it in the connecting shaft direction and rotates it counterclockwise to open the gas flow passage in the original cock 3 so that the gas from the main burner flows and the operation knob 2 will be described later. The micro switch turns to "ON", the igniter operates, and sparks are emitted from the spark plug. A gas inlet 4 is rotatably connected to the head of the former cock 3, and a main burner 5 is connected to the gas inlet 4. Inside the case 1, a dry battery 7 and an igniter 8 as an ignition mechanism are arranged with a battery case 6 interposed between the original cock 3. The (−) side of the battery 7 is electrically connected to the (−) side of the igniter 8 via the lead wire 9, and the (+) side of the battery 7 is electrically connected to the microswitch 11 via the lead wire 10. At the same time, the micro switch 11 is electrically connected to the (+) side of the igniter 8 via the lead wire 12, and as described above, the micro switch 11 is operated (ON) by the operation of the operation knob 2 and at the same time. The igniter 8 is set to operate. A branch pipe 13 is connected to the main cock 3, and gas from the main burner 5 flows through the main cock 3 to have a large number of gas outflow holes from the branch pipe 13 and a plurality of gas outlets 14 attached to the branch pipe 13. It flows into the bar burner 15. A pilot pipe 16 is connected to the original cock 3, and the tip of the pilot pipe 16 is a nut member 19 having a plurality of gas outlets fixed to a mounting plate 18 via a mounting plate 17 fixed to the case 1. The gas from the connected pilot pipe 16 flows out from each gas outlet of the nut member 19 and flows into a plurality of pilot burners 20 radially arranged on the mounting plate 18 corresponding to the gas outlets. Has become. A spark plug 21 for igniting the pilot burner 20 is fixed to the mounting plate 18 via an insulator 22, and the spark plug 21 is ignited via a lead wire 23 covered with an insulating pipe. 8 is electrically connected.

Since the ignition device of the present invention has the above-mentioned configuration, when the operation knob 2 is pressed and rotated counterclockwise, the original cock 3 becomes "open" and the raw gas from the main burner 5 is removed from the original ignition. The gas flows from the branch pipe 13 to each rod burner 15 through the inside of the rack 3, and also flows out from each gas outlet of the nut member 19 via the pilot pipe 16 to each pilot burner 20. On the other hand, at the same time, the micro switch 11 is turned "ON" to close the operation circuit of the igniter 8, the igniter 8 operates, and a spark is emitted from the ignition plug 21. With this spark, each pilot burner 20 is ignited, At the same time, each pilot burner 20 ignites each rod burner 15. As long as the rotary operation of the operation knob 2 is held, the spark is emitted from the ignition plug 21, that is, the spark is continuously emitted until the rod burner 15 is ignited.

When the rod burner 15 is ignited and the operation knob 2 is released, the micro switch 11 is automatically turned “OFF”, the operation of the igniter 8 is stopped, the spark of the ignition plug 21 is extinguished, and the main burner 5 More gas continues to flow. When the operation knob 2 is returned to its original position, the original cock 3 is "closed" and the flow of gas from the main burner 5 is stopped.

[0009]

[Effect of device]

 According to the ignition device of the present invention, the battery 7, the micro switch 11, the igniter 8 and the like are compactly arranged in the case 1, so that the entire device is downsized and the operation knob 2 is pushed and rotated. Since the gas is supplied and the rod burner 15 is ignited at the same time by the operation, the operability is excellent, and the spark of the ignition plug 21 continues to be emitted until the rod burner 15 is ignited. However, there are no ignition mistakes as in the past, and there is no fear of filling with raw gas or burns, and it is excellent in safety.
