て安定的に作動させる構成が要望されている。[Background Art] Conventionally, in a gas ignition device that supplies gas to a burner section by operating an operation button and operates an ignition means to ignite the gas in the burner section, as shown in FIG. 29, an ignition button 1a, There was a problem in that the fire extinguishing button 1b and the gas amount adjustment lever 1c were provided independently, and their operability was low. To solve this problem, the number of operation buttons is reduced to one, gas is supplied to the burner by pressing the operation button, and the amount of gas is changed and adjusted by rotating the pressed operation button. There is also a configuration in which the ignition means is operated at the end of the rotation to ignite the ignition, but in such a configuration, the ignition operation in the burner section is performed by pressing the operation button and then rotating the operation button. In this case, when the ignition operation is performed in two steps, it takes a short time to reach a gas concentration sufficient for ignition in the burner section during the initial ignition in the burner section. Another problem was that the two operations of pushing and rotating had to be repeated many times, resulting in poor operability for ignition. In addition, when extinguishing a fire, the operation button must be rotated to the closed position, and although the gas supply to the burner section can be cut off to emergency stop combustion, it is difficult to operate, and the gas supply There was a problem that it was difficult to make an emergency shutdown. Furthermore, there is a need for a configuration that can withstand considerable heating and operate stably over a long period of time in terms of ignition and extinguishing configurations.

調整することができるようにしてある。 A valve casing 10 made of die-cast aluminum is attached to the top surface of the board 9 with screws.
The valve casing 10 has an inlet 11 and an outlet 1.
2 is formed so that the gas introduced from the inlet 11 can be supplied to the burner section 2 through the outlet 12. Valve casing 1
Inside the 0, from the vicinity of the inlet 11 to the outlet 12, there are a valve hole 14 for the safety valve 13, a valve hole 15 for the main valve 21 as the gas supply valve V, and a valve for the gas amount adjustment valve 8. A hole 16 is formed. The safety valve 13 that opens and closes the valve hole 14 is a solenoid valve, and a push rod 18 is pushed in when the operation button 1 is pressed.
The valve body 13a of the safety valve 13 is moved away from the valve hole 14 against the spring 19 to open the safety valve 13, and the combustion in the burner section 2 is made heat-sensitive by the thermocoupling T electrically connected to the safety valve 13. The open state of the safety valve 13 is maintained based on the result of heat sensitivity associated with combustion, and this open state is maintained regardless of the separation of the push rod 18 from the valve body 13a due to returning the operation button 1. If the combustion in the section 2 is unexpectedly extinguished and cut off, a safety valve 13 of the electromagnetic valve is automatically closed by a non-thermal signal from the thermocoupling T to ensure safety. A main body 21 as a gas supply valve V is attached to a push rod 18 in the valve hole 15 for the main valve 21, and the main valve 21 is opened by pushing the operation button 1 against the spring 20. When the pushing force on the operation button 1 is released, the main valve 21 can be returned together with the push rod 18 via the spring 20 and the main valve 21 can be closed. The gas amount adjusting valve 8 is provided in the valve hole 16 for the gas amount adjusting valve 8, and the gas amount adjusting valve 8 is moved into and out of the valve hole 16 in conjunction with the rotation operation of the operation button 1 (described later). This allows the amount of gas flowing from the valve hole 16 to the burner section 2 to be changed and adjusted.

できるようにしてある。 In the gas supply path 4 on the downstream side of the main valve 21 in the gas supply direction within the valve casing 10, a bypass 5 is formed that communicates a portion near the main valve 21 with a portion upstream of the gas amount adjustment valve 8. , an on-off valve 6 is provided at the inlet portion of this bypass 5.
The on-off valve 6 is opened by pushing the valve stem 22 when the operating button 1 is pushed to the ignition position, which is the deepest part of the pushing stroke S, and the valve stem 22 is returned by the spring 23 when the operating button 1 returns. The bypass valve hole 24 can be closed by closing the on-off valve 6 and closing the bypass valve hole 24.

ても充分に点火を行うことができるのである。 In this way, the bypass 5 that increases the amount of gas supplied to the burner section 2 is connected to the gas supply path 4 that supplies gas to the burner section 2, and the opening/closing operation of the on-off valve 6 provided in the bypass 5 is controlled by the operation button 1. By configuring the structure so that it can be opened and closed in conjunction with the ignition operation, gas is supplied from the gas supply path 4 to the burner section 5 by pressing the operation button 1 at the time of ignition, and the bypass 5 is
By opening the on-off valve 6, the amount of gas from the bypass 5 is increased, and even if the amount of gas is set to a small amount (weak), sufficient ignition can be achieved.

次ぎに操作釦１の操作系を詳述する。 Next, the operation system of the operation button 1 will be explained in detail.

するのである。 However, in the combustion state where the operation button 1 protrudes from the operation panel P as shown in FIG.
The locked piece 65 of the presser plate 62 is hooked on the hook portion 71 of the lock piece 68, and the presser plate 62 is prevented from being returned by the spring 20 via the push rod 18, and the main valve 21 maintains its development. In such a combustion state, when the operation button 1 is pushed in, the pin 7 rotates the cam plate 36 to the left as shown in FIG. , release the lock piece 68, release the lock, push the presser plate 62 toward the operation button 1 with the push rod 18, close the main valve 21, and press the operation button 1 in this way to close the main valve 21. It closes mechanically. Next, as shown in FIG. 25, by pushing in the operation button 1 which is close to the operation panel P and is in the extinguishing position, the above-mentioned ignition operation is performed and the locked piece 65 of the presser plate 62 engages the locking piece 68. By rotating against the coiled spring 70, the locked piece 65 passes through the hook part 71 of the locking piece 68, and in the return process after ignition, the hook part 71 engages with the locked piece 65 and holds it down. A lock is applied to prevent the plate 62 from returning further, and only the operation button 1 is returned to maintain the open state of the main valve 21 in which the push rod 18 is pushed in by the locked presser plate 62.

おいて有利にできるという利点がある。[Effects of the invention] In summary, the present invention is configured to open the gas supply valve and supply gas to the burner section and operate the ignition means by pressing the operation button. It can be done with one action of pressing a button, and at the time of initial ignition in the burner section,
Since it takes a short time to reach a sufficient gas concentration for ignition in the burner section, the ignition operation is performed many times, but the ignition operation requires only one action of pushing the operation button many times. The operability can be greatly improved compared to the conventional method that performs two movements of pushing and rotating many times. The mechanical ignition maintaining means is unlocked and extinguished when the button is pushed into the operation standby position, so the mechanical ignition maintaining means is released by pushing in the operating button in the protruding position after the ignition operation. The fire can be extinguished by closing the gas supply valve.
Combustion in the burner section can be stopped easily and easily by pressing the operation button, and the fire extinguishing structure can be mechanically configured by using a mechanical cam mechanism. The effects of heat can be avoided compared to traditional fire extinguishing configurations,
This has the advantage of reducing the need to take heating measures, which is advantageous in gas igniters.
