Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a wick up/down device for a wick up/down oil combustor which greatly reduces the occurrence of bad odors during manual extinguishing.

0002

[Prior Art] Upper and lower wick type petroleum combustors are required to be equipped with a mechanism that automatically extinguishes fire due to vibrations such as earthquakes. Structures that automatically extinguish fires by descending to the ground are becoming common. In an emergency, it is now possible to extinguish a fire within 10 seconds, but after extinguishing, a large amount of unburned gas is released from the wick, and this unburned gas is thermally decomposed by the high-temperature combustion tube. It emitted a foul odor into the surrounding area.

[0003] Furthermore, in order to increase the reliability of extinguishing a fire, the wick during automatic extinguishing is lowered to a very low position from the top of the wick storage cylinder, and even when extinguishing manually, the wick is lowered to such a low position. Then, the fire may be extinguished instantly,
Normally, the lowering position of the wick is kept at a relatively high position during manual extinguishing.

0004

[Problem to be solved by the invention] If the position of the lowered wick is kept high in this way, the oil will continue to vaporize from the wick even after the fire has been extinguished, and the fire will gradually weaken until the fire is extinguished, resulting in incomplete combustion. The amount of gas generated is very small, and the generation of bad odors can be suppressed.

On the other hand, as a result of the installation of automatic fire extinguishing systems, there is a demand for extinguishing oil burners with one touch using this automatic fire extinguishing system. A wick up/down device incorporating a mechanism for operating a fire extinguisher has been put into practical use.

However, since automatic fire extinguishing systems use the same structure that extinguishes fires by vibrations caused by earthquakes, etc., even when one-touch extinguishing is used, the fire extinguishes within 10 seconds, and each time a fire is extinguished, a large amount of bad odor is generated. Even if there was a wick up/down device to suppress the generation of bad odors during normal manual extinguishing, this could not be used for one-touch extinguishing.

[0007]

[Means for Solving the Problems] The present invention relates to a wick up/down device that can suppress the generation of bad odors even with one-touch extinguishing. A drive plate 4 provided on the core vertical shaft 3 is provided, and the drive pin 5 attached to the core vertical operation lever 2 is fitted into a long hole 6 provided on the drive plate 4, and the core vertical operation lever 2 is fitted.
In the lead up/down device which rotates the lead up/down shaft 3 via the drive plate 4 during rotational operation, the rotary shaft 1 of the lead up/down operation lever 2 has a first rotary plate which rotates around the rotary shaft 1. 7 and a second rotary plate 8, each of the rotary plates 7 and 8 is provided with return springs 9 and 9a that bias rotational force in the core lowering direction, and contact portions 10 and 10a of the core vertical operation lever 2. and steps 13 and 13a that engage with the first stopper 11 and second stopper 12 against the force of the return springs 9 and 9a are provided, and the second stopper 12 is provided with a manual extinguishing operation section 14, In addition, the first stopper 11 is provided with a vibration-sensitive weight 15 and a stopper operation part 16 that is linked to the second stopper 12, and the first rotary plate 7 is provided with a vibration-sensitive weight 15 and a stopper operation part 16 that restricts the movement of the core up and down operation lever 2 in the core lowering direction. A second contact portion 17 is provided.

[0008]

[Operation] When the core up/down operation lever 2 is pushed down, the core up/down operation lever 2 rotates around the rotating shaft 1, and the drive pin 5
is fitted into the elongated hole 6, and as the drive pin 5 moves, the drive plate 7 rotates the core vertical shaft 3 in the center raising direction. Also, when the core up/down operation lever 2 is pushed down, the contact parts 10, 10
The first rotary plate 7 and the second rotary plate 8 are also rotated together via a, thereby stretching the return springs 9 and 9a. When the core up/down operation lever 2 is further pushed down, the stepped portions 13 of the first and second rotary plates 7 and 8
・13a is the first stopper 11 and the second stopper 1
2, and resists the returning force of the return springs 9 and 9a.
The second rotating plates 7 and 8 are held in the centering position. (See Figure 5)

The fire extinguishing operation in the operation of an ordinary oil combustor is carried out by lifting the wick up/down operation lever 2, and the drive pin 5 of the wick up/down operation lever 3 moves the drive plate 4 through the elongated hole 6. The core vertical shaft 3 is rotated in the core lowering direction. At this time, the lead up/down operation lever 2 can rotate until it comes into contact with the second contact portion 17 of the first rotary plate 7, and at the position where this rotation is stopped, the rotation angle of the lead up and down shaft 3 is small, so that the lead is in the lead housing tube. It does not extinguish the fire instantaneously even if it is stored in the room, and can extinguish the fire slowly without producing a bad odor.

On the other hand, when the second stopper 12 is moved by the manual extinguishing operation part 14 for one-touch extinguishing during combustion, the engagement between the second stopper 12 and the stepped portion 13a of the second rotary plate 8 is disengaged, and the second rotation is stopped. The plate 8 is rotated by the force of the return spring 9a. At this time, since the abutting portion 10a of the second rotary plate 8 is in contact with the core vertical operation lever 2, the core vertical operation lever 2 also rotates together with the second rotary plate 8, and the core vertical shaft 3 moves the core vertically. lower it. When the wick up/down lever 2 comes into contact with the second contact part 17, the rotation of the wick up/down operation lever 2 is stopped and the wick is lowered to the position where the wick is manually lowered and extinguished, so no foul odor is generated even when extinguishing with one touch. The fire can be extinguished slowly. (See Figure 4)

Furthermore, when the vibration-sensitive weight 15 falls due to vibrations such as an earthquake during combustion, the first stopper 11 moves, and the engagement between the first stopper 11 and the stepped portion 13 of the first rotary plate 7 is disengaged. Since the first stopper 11 and the second stopper 12 have a stopper operating section 16 attached thereto, when the first stopper 11 moves, the second stopper 12 is also linked to move by the stopper operating section 16.
When the second stopper 12 moves, the engagement between the second stopper 12 and the stepped portion 13a of the second rotary plate 8 is also disengaged. For this reason,
The first and second rotary plates 7 and 8 are rotated by the force of the return springs 9 and 9a, the contact parts 10 and 10a rotate the core vertical operation lever 2, and the core vertical shaft 3 lowers the core.

By the way, during one-touch extinguishing, the second contact portion 17 of the first rotary plate 7, which restricts the rotation of the core up/down operation lever 2, is connected to the first and second rotary plates when extinguishing due to the operation of the vibration-sensitive weight 15. Since 7 and 8 rotate together, they no longer act as a restrictor, and the lead up/down operation lever 2 can have a large movable angle to lower the lead to a low position. Therefore, oil burners can now be extinguished within 10 seconds. (See Figure 1)
