It comes to face 4

The core raising / ignition operation is completed as described above. When the combustion starts, the amount of combustion can be adjusted by moving the above-mentioned core up-down lever 6 up and down. Regarding the adjustment of the amount of combustion by operating the core up-and-down fine adjustment mechanism 20, Figs. 5A and 6A- Sixth
This will be described with reference to FIG. First, as shown in FIG. 5A, when the wick 3 is set to the maximum combustion position, the rack 23 is set to the position facing the core raising pinion 32 and the core lowering pinion 34 as described above. If you want to reduce the amount of combustion 6
As shown in FIG. A, when the core lowering operation body 28 provided on the base body 25 is operated in the direction of the arrow Sa, the contact piece 28b pushes the protruding piece 30a of the core lowering slide body 30, and the core lowering slide body 30.
Slides inside the bearing 31b provided on the base body 25 like Fa,
The center-lowering pinion 34 pivotally supported by the center-raising slide body 30 engages with the rack 23 which is normally in a non-coupling state and rotates in the direction of arrow D as it is to push up the rack 23 in the direction of arrow E. . As a result, the lead up / down lever 6 is also pushed up in the direction of the arrow E via the adjuster lever 21a and the auxiliary lever 21 to which the rack 23 is attached, so that the wick 3 is lowered. At this time, when the operation body 28 for lowering the core is pushed once, the core lowering pinion 34 is moved to the rack 23.
It is dimensioned to send only one tooth. When the center lowering pinion 34 finishes feeding one tooth of the rack 23, the center lowering slide body 34 is moved to the original position shown in FIG. 6B by the urging force of the center lowering slide return spring 38 which is engaged with the support shaft 35. With returning to the state of, the core lowering operation body 28 also returns to the original state,
The engagement between the centering pinion 34 and the rack 23 is disengaged. Further, the core lowering pinion 34 returns to the original state because the core lowering pinion return spring 40 is always biased in the direction of the arrow G. That is, by the action of the clutch mechanism 24, the linkage with the core up / down lever 6 of the core up / down mechanism 5 is disconnected, and the original state is restored. By the above operation, the wick 3 can be lowered in small steps, and the combustion amount can be gradually reduced.

Next, in the case of increasing the combustion amount, it is sufficient to operate the core raising operation body 27. That is, as shown in FIG. 6C, the center raising operation body 2 rotatably fitted in the center lowering fulcrum shaft 26a.
When 7 is operated in the direction of the arrow Sb, the contact piece 27b pushes the protruding piece 29a of the centering slide body 29, and the centering slide body 29 slides in the bearing 31a provided on the base body 25 as shown by the arrow Fb. Moved and the center-raising pinion pivotally supported by the center-raising slide 29.
Normally, 32 is engaged with the rack 23 which is normally in a non-coupling state and rotates in the direction of arrow H as it is, and pushes down the rack 23 in the direction of arrow J. That is, the core up / down lever 6 is pushed down in the direction of arrow J, so that the wick 3 is raised. At this time, as in the case of lowering the core, when the core raising operation body 27 is pushed once, the core raising pinion 32 has such a dimensional relationship that only one tooth of the rack 23 is fed. When the center lifting pinion 32 finishes feeding one tooth of the rack 23, the center lifting slide body 29 moves to the spindle 33.
6B is returned to the original state by the urging force of the center-raising slide return spring 36 that is engaged with the center-raising pin 27 and the center-raising pinion 32 and the rack.
23 mesh disengages. Further, the center-raising pinion 32 returns to its original state because the center-lowering pinion return spring 39 is constantly urged in the direction of arrow K.

Although the wick 3 is in a raised position by operating the wick up / down fine adjustment mechanism 20 as described above, it is set to a position lower than the maximum combustion position set by pushing down the wick up / down lever 6 during ignition. That is, the position of the uppermost tooth 23b of the rack 23 is set so as to stand up from the combustion cylinder 4 even if the core raising operation body 27 is continuously operated from the minimum combustion position finely adjusted by the operation of the core lowering operation body 28. The flame is set within a range where it is surely contained in the combustion appliance, and the centering pinion 32 is set to a position where the teeth of the rack 23 cannot be fed any further. Therefore, as shown in FIG. 5B, the uppermost tooth 23b of the rack 23 is set to the maximum combustion position, and then the gauge protrusion 23a provided on the rising side end of the wick 3 from the tooth to which the core lowering pinion 34 first engages. Since it is set depending on the standing flame condition due to continuous operation of the core raising operation body 27, the fine adjustment of the combustion amount can be performed with confidence. Further, since the maximum combustion position and the uppermost tooth 23b of the rack 23 are not aligned, the variable width of the combustion amount can be increased correspondingly.

FIG. 7 shows an example of an oil combustor using the core lifting device of the present embodiment. 41 is a door attached to the base body 25, and 42 is a door.
Is an ignition knob attached to the tip of the ignition lever 9, 43
Is a core up / down knob attached to the tip of the core up / down lever 6. As the operation procedure of the user, first, the door 41 is opened, and the ignition knob 42 and the core upper and lower knobs 43 inside the door 41 are pushed down to ignite the wick 3, and after confirming the ignition, the door 41 is closed. When the combustion starts and becomes stable, the amount of combustion is usually adjusted by the operation body 28 for lowering the core and the operation body 27 for raising the core outside the door 41. 44 is an emergency fire extinguishing button also provided outside the door 41
It is a fire extinguisher operating body connected to 19.

EFFECTS OF THE INVENTION As is clear from the above description of the embodiments, the core up / down device of the present invention uses the core up / down mechanism in addition to the core up / down fine adjustment mechanism so that the core can be moved up and down in small steps. After performing the wick raising operation for ignition, the wick top and bottom fine adjustment mechanism can finely adjust the combustion amount. In particular, the combustion amount can be adjusted in small steps, so the combustion amount can be adjusted digitally.
That is, the core height is changed by a fixed amount for each step, and as a result, the user can easily know the adjustment range of the combustion amount, and the usability is dramatically improved. Further, the fine adjustment on the core rising side is highly safe because the feed is regulated depending on the standing flame condition.
