5 is a combustion tank, 56 is a core guide cylinder, 57 is a core outer cylinder, 58
Is a combustion cylinder.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the petroleum combustor having the above-described structure, the stove body has been downsized recently, and accordingly, the distance 1 from the pivot point 54 of the lever 53 becomes short, and the lever 53 has a small amount. There is a problem that the wick 51 moves largely by operation, and when the user tries to adjust the combustion amount a little, it is difficult to make fine adjustment, and in terms of usability it is just a step away.

The present invention has been made in view of such a point, and an object thereof is to make it possible to easily and surely adjust the combustion amount.

Means for Solving the Problems In order to achieve the above object, the present invention provides a manually operated core up-and-down mechanism for vertically moving a wick, and a core up-and-down mechanism when not normally linked to the core up-and-down mechanism. A core up-and-down fine adjustment mechanism for engaging and driving this in small increments is provided, and the above-mentioned core up-and-down pinion for finely adjusting the up-and-down core are arranged above and below the center line of the shaft that pivotally supports the up-and-down core mechanism. It is a set up configuration.

Operation The present invention can adjust the combustion amount by either the core up / down mechanism or the core up / down fine adjustment mechanism according to the above-described configuration. Therefore, first, the core up / down mechanism can adjust the core up / down or a large amount of combustion for point extinguishing. After that, the fine adjustment mechanism for adjusting the upper and lower parts of the core makes it possible to easily and surely adjust the combustion amount little by little.

EXAMPLE An example will be described below with reference to FIGS. 1 to 7.

First, in FIGS. 3 and 4, 1 is a core guide cylinder, 2 is a core outer cylinder which is arranged on the outer periphery of the core guide cylinder 1 with a gap, and 3 is between the core guide cylinder 1 and the core outer cylinder 2. Wick provided vertically on the 4
(See FIG. 6) is a combustion cylinder for burning the fuel vaporized from the wick 3.

Next, a manually operated core up / down mechanism 5 for vertically moving the wick 3
The same will be described with reference to FIGS. 3 and 4. First, reference numeral 6 denotes a core upper and lower body (hereinafter referred to as a core vertical lever) for moving the wick 3 up and down, and one end of the wick is linked to the wick 3 through an appropriate linking means. The core up-down lever 6 is rotatably supported by a pin 8 (see FIG. 1) on a core up-down board 7 in the middle thereof. Reference numeral 9 denotes an ignition lever pivotally supported on the core upper and lower base plate 7 by a pin 8 together with the core upper and lower lever 6, and one end portion 9a of the ignition lever operates an ignition device (not shown) to ignite the wick 3. After operation, it automatically returns to its original position. 10
Like the ignition lever 9, is a core upper / lower plate pivotally supported on the core upper / lower base plate 7 by a pin 8 together with the core upper / lower lever 6, and is linked to the core upper / lower lever 6 by an appropriate means. Reference numeral 11 denotes a spring for urging the core upper and lower plates 10 toward the upper position (the wick lowering position), which is hooked between the end of the core upper and lower plates 10 and the core upper and lower substrates 7. 12 is the core upper and lower plates 1

It is pivotally supported by a pin 12a. The lock plate 12 is formed with a long hole 14 into which the pin 13 planted in the upper and lower core plates 10 is inserted, and a locking portion 14a is formed at the terminal end of the long hole 14 to lock the pin 13. It is like this. That is, when the core up / down lever 6 is pushed down (in the direction of raising the wick), the core up / down plate 10, which is linked to the core up / down lever 6 by an appropriate means, rotates downward (the pin 13 of the core up / down plate 10 is inserted into the elongated hole 14). Down along that slot 1
4), the pin 13 fits into the locking portion 14a and locks the core upper and lower plates 10 at that position in spite of the biasing force of the spring 11. 15 is a lock plate 12

A clutch mechanism 24 is constituted by the rack 40 and the rack 23, and the tip end portions 32a and 34a of the core raising pinion 32 and the core lowering pinion 34 are provided with the core up-down lever 6 and the auxiliary lever 21 as shown in FIG. 5A. They are arranged substantially evenly above and below the supporting axis center line X.

Next, the operation of the core lifting device for an oil combustor configured as described above will be described below.

First, from the state before use in FIGS. 1 and 3 to the core up-down lever 6
4 is pushed down, the wick 3 rises at the combustion position as shown in FIG. 4, and an ignition device (not shown) is operated via the ignition lever 9 to ignite the wick 3. Then, the ignition lever 9 returns to the original state. At this time, the core up / down lever 6
The auxiliary lever 21 integrally mounted on the auxiliary lever 21 also performs the same rotational movement as the core up / down lever 6, and the rack 23 mounted on the auxiliary lever 21 raises the center of the core up / down fine adjustment mechanism 20.
It comes to face the core lowering pinions 32 and 34.

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-and-below core up / down lever 6 up and down. Regarding the adjustment of the amount of combustion by operating the core up / down fine adjustment mechanism 20, see FIGS. 5A to 5C. It demonstrates using. First, as shown in FIG. 5A, when the wick 3 is set to the 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. When the combustion amount is reduced, the core lowering operation body 2 provided on the base body 25 as shown in FIG. 5C.
When 8 is operated in the direction of 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 core lowering pinion 34 pivotally supported by the core raising slide body 30 is normally in the non-coupling rack 23.
, And the rack 23 is pushed up in the arrow E direction. As a result, the lead up / down lever 6 is also pushed up in the direction of arrow E via the auxiliary lever 21 to which the rack 23 is attached, so that the wick 3 is lowered. At this time, when the core lowering operation body 28 is pushed once, the core lowering pinion 34 has such a dimensional relationship that only one tooth of the rack 23 is fed. 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. 5A by the biasing force of the center lowering slide return spring 38 which is engaged with the support shaft 35. Return to the state of, and the operation body 2 for lowering the core
8 also returns to the original state, the core lowering pinion 34 and the rack 23
The disengagement of 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, when increasing the combustion amount, the operation body 27 for raising the core
You can operate. That is, as shown in FIG. 5B, when the center-raising operation body 27 rotatably fitted to the center-lowering fulcrum shaft 26a is operated in the arrow Sb direction, the contact piece 27b moves the center-raising slide body 29. When the projecting piece 29a is pressed, the centering slide body 29 slides in the bearing 31a provided in the base body 25 as shown by an arrow Fb, and the centering pinion 32 pivotally supported by the centering slide body 29 is normally Engages with the rack 23 in the non-coupling state and rotates in the direction of arrow H as it is,
Push up 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, when the core raising operation body 27 is pushed once as in the case of the core lowering, the center raising pinion 32
Has a dimensional relationship such that only one tooth of the rack 23 is fed. When the center-raising pinion 32 finishes feeding one tooth of the rack 23, the center-raising slide body 29 is moved by the urging force of the center-raising slide return spring 36, which is engaged with the support shaft 33, as shown in FIG. When returning to the state, the centering operation body 27 also returns to the original state, and the engagement between the centering pinion 32 and the rack 23 is disengaged. Further, the core-raising pinion 32 returns to its original state because the core-lowering pinion return spring 39 is constantly urged in the direction of arrow K.

As described above, in this combustor, the amount of combustion can be adjusted by the core up / down mechanism 5 and the amount of combustion by the core up / down fine adjustment mechanism 20, and the core up / down mechanism 5 and the core up / down fine adjustment mechanism 20 can be adjusted.
Is normally in a non-linked state, the wick 3 can be freely lowered to extinguish the fire by the wick up / down mechanism.

Further, the upper and lower pinions 32, 34 (32a, 34a) are arranged substantially evenly above and below the center line of the shaft fulcrum about which the rack 23 rotates, so that the two pinions 32, 34 engage with the rack 23. Since the rotation is performed at the apex of the rotational movement of the rack 23, stable feeding can be obtained in both the ascending and descending directions, and the core fine adjustment can be performed finely.

Further, in this embodiment, the core raising / lowering pinions 32, 34
The rack 23 set so as to face with the core is not in the entire region of the vertical stroke of the core, but in a part thereof, that is, in the range where combustion is normally maintained, for example, when the non-gas characteristic (CO / CO ₂ ) is J
The length is set so that it is located only within the range within the IS standard. That is, the lowermost teeth 23a of the rack 23 are positioned so that the core-lowering pinion 34 cannot feed the teeth of the rack 23 below the height at which the wick 3 can normally burn. Similarly, the uppermost teeth 23b of the rack 23 are positioned such that the centering pinion 32 cannot feed the teeth of the rack 23 beyond the height at which the wick 3 can normally burn. Therefore, when the operation of the core raising / lowering operating bodies 27, 28 is repeated several times and the center raising / lowering pinions 32, 34 send the lowermost tooth 23a or the uppermost tooth 23b, the wick 3 is moved up and down further. It can no longer be moved, and the amount of combustion can be finely adjusted with peace of mind.

FIG. 6 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, 42 is an ignition knob attached to the tip of the ignition lever 9, and 43 is an ignition knob. 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, open the door 41 and push up the ignition knob 42 and the core upper and lower knobs 43 located inside thereof to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the core lowering knob Operating body 2
8 and the operation body 27 for raising the core adjust the combustion amount.

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. point·
After adjusting the top and bottom of the core and a large amount of combustion to extinguish the fire,
The fine adjustment mechanism for vertical adjustment of the core allows the combustion amount to be adjusted little by little, and the adjustment can be performed reliably and easily by the action of the pinions arranged substantially vertically above and below the center line of the shaft fulcrum about which the rack rotates. In particular, the combustion amount can be adjusted in small steps, so the combustion amount can be adjusted digitally, that is, the core height can be changed by a fixed amount for each step, and as a result, the user can easily adjust the amount of combustion. By becoming able to know in, usability is dramatically improved. In addition, since the core up / down mechanism and the fine adjustment mechanism are usually not linked, the combustion amount can be freely adjusted by each mechanism.For example, the fine adjustment of calories is a motor drive system, and even if the motor fails, the core up / down mechanism can be adjusted. The mechanism makes it possible to operate the core up and down, resulting in high safety.
