Next, the operation of the oil combustor wick up-and-down device configured as described above will be explained below.

First, from the state before use as shown in Figures 1 and 3,
When pressed down, the wick 3 rises to the combustion position as shown in FIG. 4, and an ignition device (not shown) is actuated via the ignition lever 9 to ignite the wick 3. The ignition lever 9 then returns to its original state. At this time, the core upper and lower numbers are 6
The sub-lever 21 integrally attached to the core vertical lever 6 also performs the same rotational movement as the core vertical lever 6, and the rack 23 attached to the sub-lever 21 is connected to the core barb of the core vertical fine adjustment mechanism 20.
It comes to face the core lowering pinions 32 and 34.

As described above, the wicking and ignition operations are completed.

Once combustion starts, the amount of combustion can be adjusted by vertically moving the wick up/down lever 6, but the wick up/down fine adjustment mechanism 2
Adjustment of the combustion amount by manipulating 0 will be explained using FIGS. 5A to 5C. First, as shown in Figure 5A, the wick 3
When the rack 23 is set to the combustion position, the rack 23 is set in a position facing the core raising pinion 32 and the core lowering pinion 34 as described above. When considering the amount of combustion, the fifth
As shown in FIG. slides in a bearing 31b provided on the base body 25 like Fa, and the centering pinion 34 pivotally supported by the centering slide body 30 engages with the rack 23, which is normally in an uncoupled state, and remains as it is. The rack 23 is rotated in the direction of the arrow E, and the rack 23 is pushed up in the direction of the arrow E. the result,
The wick up/down lever 6 is also pushed up in the direction of arrow E via the sub-lever 21 to which the fertilizer rack 23 is attached, so that the wick 3 is lowered. At this time, if the center lowering operation body 28 is pressed once, the center lowering pinion 3
4 has a dimensional relationship such that only one tooth of the rack 23 is advanced. When the core lowering pinion 34 finishes feeding one tooth of the rack 23, the core lowering slide body 34 is moved by the biasing force of the core lowering slide spring 38 engaged with the support shaft 35 as shown in FIG. 5A. At the same time that the centering operation body 28 returns to its original state, the centering pinion 34 and the rack 23 are disengaged from each other. Also, the core lowering pinion 34
The core lowering pinion return spring 4o is always energized in the direction of arrow G, so that it returns to its original state. That is, by the action of the clutch mechanism 24, the link between the lead up/down mechanism 5 and the lead up/down lever 6 is disconnected, and the original state is restored. By the above-described operation, the wick 3 can be lowered little by little, and the amount of combustion can be reduced little by little.

Next, when increasing the speed of desire, raise the core, l”E
All you have to do is operate the l operating body 27. That is, as shown in FIG. 5B, when the centering operation body 27 rotatably fitted into the centering fulcrum shaft 26a is operated in the direction of arrow sb, the abutment piece 27b moves from the centering slide 29. By pressing the protruding piece 29a, the centering slide 29 slides in the bearing 31a provided on the base body 25 in the direction of arrow Fb, and the centering pinion 32 pivotally supported by the centering slide 29 normally moves. It engages with the uncoupled rack 23 and rotates in the direction of arrow H, pushing down the rack 23 in the direction of arrow J. In other words, there is no need to push down the wick up/down lever 6 in the direction of arrow J, so that the wick 3 will rise. At this time,
The dimensions are such that when the centering operation body 27 is pressed once, the centering pinion 32 moves only one tooth of the rack 23, as in the case of centering. The centering pinion 32 is the rack 2
After feeding one tooth of No. 3, the centering slide 29 moves back to the centering slide return spring 3 which is engaged with the support shaft 33.
6 returns to the original state shown in FIG. 5A, and the centering operation body 27 also returns to its original state), and the centering pinion 32 and rack 23 are disengaged from each other. Further, the centering pinion 32 returns to its original state because the centering pinion return spring 39 is always biased in the direction of the arrow.

As described above, in this combustor, the combustion amount can be adjusted by the wick up/down mechanism 5 and the wick up/down fine adjustment mechanism 20, and the wick up/down mechanism 5 and the wick up/down fine adjustment wick up/down mechanism 20 are normally Since it is in an uncoupled state, the wick 3 can be freely lowered by the wick up/down mechanism to extinguish the fire.

In addition, in this embodiment, the core raising/lowering pinion 32.34
The rack 23, which is set to face the wick, covers only a part of the wick's vertical stroke, not the entire range, that is, within the range where combustion is maintained normally, for example, when the exhaust gas characteristics (Go/GO2) are J
The length should be set only within the range that falls within the IS standard. That is, the position of the lowermost tooth 23a of the rack 23 is such that the wick lowering pinion 34 cannot send the tooth of the rack 23 below a height at which the lamp wick 3 can perform normal combustion. Similarly, the uppermost tooth 23b of the rack 23 is positioned so that the wick raising pinion 32 cannot send the teeth of the rack 23 above a height at which the wick 3 can perform normal combustion.

Therefore, by repeating the operation of the wick raising and wick lowering operation bodies 27 and 28 several times, if the wick raising and wick lowering pinions 32 and 34 send the lowermost tooth 23a or the uppermost tooth 23b, no more lamp wicks It is no longer possible to move up and down υ, allowing you to fine-tune the combustion amount with confidence.

FIG. 7 shows an example of an oil combustor using the wick up/down device of this embodiment, in which 41 is a door attached to the base body 25, 42 is an ignition knob attached to the tip of the ignition lever, and 43 is a lead up/down knob attached to the tip of the lead up/down lever 6. The user's operating procedure is to first open s41 and press the ignition knob 42 inside.
The wick upper and lower knobs 43 are pushed up to ignite the wick 3, and when combustion begins, the amount of combustion is adjusted using the wick upper and lower knobs 43, or the wick lowering operation body 28 and the wick raising operation body 27.

Next, another embodiment of the core vertical fine adjustment mechanism 20 will be described using FIG. 6. In the figure, 5o is a fine adjustment base, 51a
51b is a centering bearing portion, and 51b is a centering bearing portion. 5
Reference numeral 2 denotes a centering button, which has a slide shaft portion 52a that slides within a centering bearing portion 51a, and a centering pinion 32 pivotally supported by a centering pinion shaft 53 is incorporated in the slide shaft portion 52a. There is. 54 is the fine adjustment base 5 mentioned above.
A centering button return spring interposed between 0 and the centering button 52 always applies force in the direction of the arrow.

Reference numeral 55 denotes a core lowering button, which has a slide shaft portion 55a that slides within the core lowering bearing portion 5Ib, and a core lowering pinion 3 pivotally supported on a core lowering pinion shaft 56 on the slide shaft portion 55a.
4 is included. Reference numeral 57 denotes a core lowering button return spring interposed between the fine adjustment base 50 and the core raising button 55, which always applies a force in the direction of arrow M.

In the above configuration, when the centering button 52 is pressed, the centering pinion 32 and the rack 23 move in the same manner as shown in FIG.
feeds the teeth of rack 23 one by one. Also, when the core lowering button 55 is pressed, the core lowering pinion 34 and rack 23
performs a movement similar to that shown in FIG.

As described above, this embodiment provides the same effects as those of the above-described embodiments, but has the advantage of simplifying the configuration because the button and the slide shaft can be integrated.

It should be noted that the above embodiment is shown as an example of achieving the object of the present invention, and any structure may be used as long as the object of the present invention is achieved.

Effects of the Invention As is clear from the description of the embodiments, the lead up/down device of the present invention uses a lead up/down fine adjustment mechanism in addition to the lead up/down mechanism to allow the lead up and down in small steps. point·
After raising and lowering the wick to extinguish the fire and making extensive adjustments to the combustion amount,
