Abstract

PURPOSE:To obtain an electric discharge type igniter in which a most ignitable point of a combustion wick is selected to be ignited. CONSTITUTION:A discharge electrode is opposed to an upper part of a raised combustion wick, an igniter switch 7 is closed from the midway of operation of an ignition knob 6 for moving upward the wick, and electric discharging occurs from the electrode toward the raising wick. A height of the wick is raised slightly higher than a normal combustion position during rising of the wick by applying a force to the knob 6 to always pass the wick through an optimum ignition point.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge type ignition device for a petroleum combustor which ignites a combustion wick by utilizing an electric discharge.

[0002]

2. Description of the Related Art As an igniter for an oil combustor, it is common to apply electricity from a dry cell to a thin filament to cause the filament to glow red and ignite a combustion wick.

Although a device using a dry battery as a power source has not been commercialized, as in Japanese Utility Model Publication No. Sho 63-35244, a discharge electrode for ignition is provided by sandwiching the combustion wick, and the combustion wick is ignited by using the discharge. Techniques are well known.

[0004]

The present invention relates to one of the above-mentioned prior arts, which uses the latter dry battery to ignite a combustion wick by using a discharge electrode. Those that use dry batteries,
There is a problem that the sparks are weak due to electric discharge, and when the combustion time further elapses, the height of the combustion core changes, it gets tired, tar adheres, etc., and subtle changes occur on the surface of the combustion core. In addition, the dimensions of the combustion wick and the discharge electrode may be slightly misaligned, and even if there is a discharge, the sparks separate from the combustion wick and do not ignite at all, or it is difficult to ignite with only white smoke. Due to its shortcomings, it is presumed that its commercialization has been delayed.

If the discharge type ignition device ignites smoothly, it will replace the filament system, which is highly worn out and has many defects such as deformation and disconnection. As can be seen, the applicant is trying to put the discharge type ignition device into practical use.

[0006]

In order to solve the above-mentioned problems, the present invention mounts a combustion wick 4 which moves up and down by rotation of a wick vertical shaft 3 between an inner-core cylinder 1 and an outer-core cylinder 2, Inner / Outer cylinder 1
・ Discharge electrode 5 by looking into the combustion wick 4 exposed at the upper part of 2.
In an oil combustor equipped with 5a, an ignition knob 6 for rotating the core up-down shaft 3 in the direction of raising the core and an igniter switch 7 for opening / closing when the ignition knob 6 is activated are provided. Reference numeral 6 indicates that the igniter switch 7 is opened in the core lowering position, and the igniter switch 7 is closed in the middle of the center raising and the center raising combustion position, and the return spring 8 that urges the ignition knob 6 toward the old position is ignited. This is a discharge type ignition device for an oil combustor attached to the knob 6.

Further, on the rotary plate 9 rotatably attached to the core vertical shaft 3, a locking portion 9a interlocking with the core vertical shaft 3 and a lock portion 9b for holding the rotary plate 9 in the core raised position are provided. A core lowering spring 10 for returning the rotary plate 9 held by the lock portion 9b to the core lowering position is attached, and a rotary stopper 9c for the core vertical shaft 3 or the core vertical shaft 3 in association with the rotary plate 9 is attached, and an ignition knob 6 is provided. Rotating plate 9 that rotates together with the vertical axis 3 of the core
When the combustion wick 4 is rotated to the rotation stopper 9c further than the lock portion 9b to raise the combustion wick 4 higher, the ignition between the combustion wick 4 and the discharge electrode during the ignition operation is performed even if the height of the combustion wick 4 changes. You can get a wide range of best points.

[0008]

When the combustion wick 4 mounted on the inner and outer cylinders 1 and 2 pushes down the ignition knob 6 to rotate the wick vertical shaft 3, the wick vertical shaft 3 holds the combustion wick 4 until the rotation stopper 9c abuts. By raising, the upper edge of the combustion wick 4 is exposed above the inner and outer cylinders 1 and 2. Then, the igniter switch 7 is turned on by operating the ignition knob 6, and spark discharge between the two discharge electrodes 5 and 5a is continuously performed while the wick is rising, and the gap between the combustion wick 4 and the discharge electrode 5a is ignited. Ignite when the optimal position is reached.

The core up-down shaft 3 is attached to the rotating plate 9 by the engaging portion 9a.
The rotary plate 9 further rotates while extending the core lowering spring 10 further than the locking part of the lock part 9b of the rotary plate, and the combustion core 4 moves upward until the rotation stopper 9c abuts.

On the other hand, when the combustion wick 4 is ignited, the ignition knob 6
When the hand is released from, the ignition knob 6 returns to the old position by the force of the return spring 8, and the igniter switch 7 is opened to stop the discharge. The rotary plate 9 is slightly returned by the core lowering spring 10 until the lock portion 9b is locked, and the combustion core 4 moves to a predetermined combustion position to continue combustion. Therefore, since the combustion wick 4 always rises to the highest position where it passed the combustion position each time the ignition operation is performed, it is possible to reliably ignite even if the height of the combustion wick 4 changes.
