DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core up / down device for a core up / down type oil combustor in which the generation of a foul odor during fire extinguishing by hand is greatly reduced.

[0002]

2. Description of the Related Art A vertical core type oil combustor is obliged to have a mechanism for automatically extinguishing fire due to vibrations such as an earthquake. It has become common to automatically extinguish a fire by descending. In case of emergency, it became possible to extinguish the fire within 10 seconds, but a large amount of unburned gas was released from the wick after extinguishing, and this unburned gas was thermally decomposed by the high temperature combustion cylinder, It emitted a foul odor to the surroundings.

Further, in order to enhance the certainty of extinguishing the fire, the lead during automatic fire extinguishment is designed to drop from the upper end of the lead accommodating cylinder to a very low position, and even when extinguishing manually, the lead falls to such low position. Then, you may extinguish the fire for a moment,
Normally, the tip of the wick is designed to maintain a relatively high position when manually extinguishing a fire.

[0004]

When the position of the lowered wick by manual operation is kept high in this way, oil vaporization continues from the wick even after the fire is extinguished and the fire is extinguished while gradually weakening the heat power, resulting in incomplete combustion. The amount of gas generated is very small and the generation of offensive odor can be suppressed.

On the other hand, as a result of the automatic fire extinguisher being attached, there is a demand for extinguishing the oil combustor with one touch using this automatic fire extinguisher. Instead of operating the fire extinguisher by vibration such as an earthquake, an automatic fire extinguisher button is used. A core lifting device incorporating a mechanism for operating a fire extinguisher has been put into practical use.

However, since the automatic fire extinguisher uses the structure which extinguishes by vibration such as an earthquake as it is, it is possible to extinguish within 10 seconds even with one-touch extinguishing, and a large amount of foul odor is generated each time extinguishing. However, even if a mechanism for suppressing the generation of a foul odor during normal manual fire extinguishing is provided as the core lifting device, this cannot be used for one-touch fire extinguishing.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a core up / down device capable of suppressing the generation of a bad odor even with one-touch fire extinguishing, and includes a core up / down operation lever 2 rotatably provided around a rotary shaft 1. A drive plate 4 provided on the core up-down shaft 3 is provided, and a drive pin 5 attached to the core up-down operation lever 2 and an elongated hole 6 provided on the drive plate 4 are fitted to each other to rotate the core up-down operation lever 2. In a core up-and-down device that rotates the core up-and-down shaft 3 via the drive plate 4, the rotary shaft 1 of the core up-and-down operation lever 2 includes a first rotary plate 7 and a first rotary plate 7 that rotate around the rotary shaft 1. Two rotating plates 8 are provided, and each of the rotating plates 7 and 8 is provided with a return spring 9 and 9a for urging a rotational force in a core lowering direction, a contact portion 10 and 10a of the core up-and-down operation lever 2, and a return member. A stepped portion 13.1 that locks the first stopper 11 and the second stopper 12 against the force of the springs 9 and 9a. a, the second stopper 12 is provided with a manual fire extinguishing operation portion 14, and the first stopper 11 is provided with a vibration-sensitive weight 15 and a stopper operation portion 16 which is linked to the second stopper 12. The one rotary plate 7 is provided with a second contact portion 17 for restricting the movement of the core up-down operation lever 2 in the core lowering direction.

[0008]

When the core up / down operating lever 2 is pushed down, the core up / down operating lever 2 rotates about the rotary shaft 1 and the drive pin 5
Is fitted into the long hole 6, the drive plate 7 rotates the core vertical shaft 3 in the center-up direction as the drive pin 5 moves. When the core up / down operation lever 2 is pushed down, the contact portion 10.1
The first rotary plate 7 and the second rotary plate 8 also rotate together via 0a to stretch the return springs 9 and 9a. When the core up / down operating lever 2 is further pushed down, the stepped portion 1 of the first and second rotary plates 7 and 8
3.13a is locked to the first stopper 11 and the second stopper 12, and holds the first and second rotary plates 7 and 8 in the center-up position against the returning force of the return springs 9 and 9a. (See Fig. 5)

The fire extinguishing operation in the operation of a common oil combustor is performed by lifting the core up / down operation lever 2, and the drive pin 5 of the core 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 core up / down operation lever 2 can be rotated until it comes into contact with the second contact portion 17 of the first rotary plate 7, and the rotation angle of the core up / down shaft 3 is small at the position where this rotation is stopped. Even if it is stored in, it does not extinguish the fire instantly, and it can be extinguished slowly without producing a foul odor.

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

When the vibration-sensitive weight 15 falls down due to vibration such as an earthquake during combustion, the first stopper 11 moves and the engagement between the first stopper 11 and the step portion 13 of the first rotary plate 7 is released. Since the stopper operating portion 16 is attached to the first stopper 11 between the first stopper 11 and the second stopper 12, the second stopper 12 is also linked by the stopper operating portion 16 when the first stopper 11 moves.
When the second stopper 12 moves, the engagement between the second stopper 12 and the step portion 13a of the second rotary plate 8 is released. Because of this,
The first and second rotary plates 7 and 8 are rotated by the force of the return springs 9 and 9a, the contact portions 10 and 10a rotate the core up-down operation lever 2, and the core up-down shaft 3 descends the core.

By the way, during one-touch fire extinguishing, the second contact portion 17 of the first rotary plate 7 which regulates the rotation of the core up-down operation lever 2 is provided with the first and second rotary plates when the fire is extinguished by the operation of the vibration weight 15. Since 7 and 8 rotate together, they do not act as a restricting tool, and the wick up / down operation lever 2 has a large movable angle and lowers the wick to a lower position. Therefore, the oil combustor can be extinguished within 10 seconds. (See Fig. 1)
