DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wick up/down device for a wick type oil combustor.

Conventional technology Generally, this type of oil combustor moves the wick up and down to burn and burn.
The lamp is extinguished, and the lamp wick is moved up and down by moving a lever 53 connected to the lamp wick 51 via a pin 52, as shown in FIG. In addition, 54 in the figure is the pivot point of the lever 53, and 5
5 is a fuel tank, 56 is a core guide cylinder, 57 is a core outer cylinder, 58
is the combustion tube.

Problems to be Solved by the Invention However, in the oil combustor having the above configuration, the stove body has recently been downsized, and as a result, the distance l of the lever 53 from the pivot point 54 has become shorter. The wick 51 moves a lot, and when the user tries to slightly adjust the amount of combustion, it is very difficult to make fine adjustments, which is inconvenient, and when the wick is raised, a large flame is generated, which is dangerous.

The present invention has been made in view of these points, and it is possible to easily adjust the combustion amount, and the combustion amount can be varied over a wide range, and a large standing flame does not occur during the core raising operation. The purpose is to do so.

Means for Solving the Problems In order to achieve the above object, the present invention has a wick up/down mechanism for moving the wick up and down, and a wick up/down mechanism which is normally uncoupled with the wick up/down mechanism but is engaged with the wick up/down mechanism during operation. The structure includes a core upper/lower fine adjustment mechanism that drives this in small increments, and a selection mechanism that can select at least two upper and lower limit ranges of fine adjustment performed by the core upper and lower fine adjustment device.

Operation With the above-described configuration, the present invention first performs a wick raising operation for ignition using the wick up/down mechanism, and then easily performs small combustion amount adjustments using the wick upper fine adjustment mechanism. At least two ranges of fine adjustment by the mechanism can be selected, and by selecting a state in which the upper limit of the fine adjustment range is low, it is possible to suppress the occurrence of standing flames.

Example Examples thereof will be described below with reference to FIGS. 1 to 8.

First, in FIGS. 3 and 4, l is a core guide tube, 2 is a core outer tube arranged with a gap around the outer periphery of the core guide tube 1, and 3 is a gap between the core guide tube l and the core outer tube 2. A lamp wick that can be moved up and down, 4
(See FIG. 8) is a combustion tube that burns the fuel vaporized from the lamp wick 3.

Next, a manually operated wick up and down mechanism 5 that moves the lamp wick 3 up and down.
This will be explained using FIGS. 3 and 4 as well. First, reference numeral 6 denotes a wick upper and lower body (hereinafter referred to as a wick up/down lever) for moving the lamp wick 3 up and down, and one end thereof is linked to the lamp wick 3 via a suitable linking means.

It is something. 31d is the selection operation body 31
When the select operating body 31 is moved in the direction opposite to the biasing direction of the return spring 42, it fits into the protrusion 41a of the select click plate 41, and the select operating body 31 is moved to the "movement position". ”.

In addition, the rack 23 provided with a plurality of tooth row groups 23° and 23'', the clutch mechanism 24, and the select operation body 31 described above
, a select presser plate 40, a select click plate 41, and a select operating body return spring 42 constitute a select mechanism.

Next, the operation of the core up/down device configured as described above will be explained first with respect to the "normal position" of the selection mechanism.

First, from the state before use as shown in Figures 1 and 3,
When pushed up, the wick 3 rises to the maximum combustion position as shown in FIG. 4, and an ignition device (not shown) is activated via the ignition lever 9 to ignite the wick 3. The ignition lever 9 then returns to its original state. At this time, the auxiliary lever 21 and the adjuster lever 21a, which are integrally attached to the core upper and lower lever 6, also perform the same rotational movement as the core upper and lower lever 6, and the normal side tooth row group of the shaft 23 that is attached to the adjuster lever 21a. 23', the centering and centering lowering which are biased toward the "normal position" by the select operating body return spring 42 of the selection mechanism come to oppose the pinions 32 and 34.

As described above, the core raising and ignition operations are completed.

Once combustion starts, the amount of combustion can be adjusted by moving the wick up/down lever 6 up and down.
Adjustment of the combustion amount by manipulating 0 will be explained using FIG. 5A and FIGS. 6A to 6C. First, as shown in FIG. 5A, when the wick 3 is set to the maximum combustion position, the rack 23'' is set to a position opposite to the wick raising pinion 32 and the wick lowering pinion 34 as described above.

When reducing the amount of combustion, the base body 2 as shown in Figure 6A.
When the center-lowering operation body 28 provided at 5 is operated in the direction of arrow Sa, the contact piece 28b pushes the protruding piece 30a of the center-lowering slide body 30, and the center-lowering slide body 30 is provided on the selection operation body 31. Slides inside bearing 3Ib like Fa,
Centering pinion 3 pivotally supported by the centering slide body 30
4 engages with the rack 23'', which is normally in an uncoupled state, and rotates in the direction of the arrow, pushing the rack 23'' up in the direction of the arrow E. As a result, the rack 23'' is installed. The wick up/down lever 6 is also pushed up in the direction of arrow E via the adjuster lever 21a and the auxiliary lever 21, so the wick 3 is lowered.At this time, if the wick lowering operation body 28 is pressed once, The core lowering pinion 34 is sized so as to advance only one tooth of the rack 23'.

When the center lowering pinion 34 finishes feeding one tooth of the rack 23', the center lowering slide body 30 is moved to the sixth position by the biasing force of the center lowering slide return spring 37 which is engaged with the support shaft 35.
At the same time as returning to the original state shown in Figure B, the core lowering operating body 28
has returned to its original state, and the core lowering pinion 34 and rack 23°
The mesh will come off. Further, the core lowering pinion 34 returns to its original state because the core lowering pinion return spring 39 is always biased in the direction of arrow G. By the above-described operation, the lamp wick 3 can be lowered little by little, and the amount of combustion can be reduced little by little.

Next, when increasing the combustion amount, the core raising operation body 27
All you have to do is operate. That is, as shown in FIG. 6C, when the centering operation body 27, which is rotatably fitted into the centering fulcrum shaft 26a, is operated in the direction of the arrow sb force, the result is the same as when the centering operation body 28 is operated. This time, push down the rack 23 in the direction of arrow J. In other words, the wick 3 is pushed down in the direction of arrow J on the wick up/down lever 6.
will rise. At this time, the dimensions are such that when the centering operation body 27 is pushed once, the centering pinion 32 moves one tooth of the rack 23', as in the case of centering.

Next, switching of the selection mechanism to the "movement position" side will be explained. As shown in FIG. 7, when the select operating body 31 is moved to the right by the operating knob 31c, that is, in the opposite direction to the biasing direction of the select operating body return spring 42, the protrusion 4
1a, the select link plate 41 moves one end in the direction of the arrow due to its elasticity, and after moving, the recess 31 is formed in the select operation body 31.
d and the position is determined. This position is the "movement position", and the centering and centering pinions 32 and 34 moved together with the select operation body 31 are located in the other tooth group of the rack 23 described above, that is, the moving side tooth group 2.
It comes to face 3°゛. In this "movement position" side as well, the lamp wick 3 can be moved up and down by one tooth pitch by operating the wick lowering and wick raising operation bodies 28 and 27 in the same manner as described for the "normal position" side.

Also, when switching to the "normal position" side again, press the operation knob 31.
When applying force in the sliding direction to return c to its original position,
Due to the elasticity of the select click plate 41, the protrusion 41a moves in the direction indicated by the arrow and comes out of the recess 31d, and the select operation body 31 moves to the "normal position".

As described above, the wick 3 can be raised by one tooth pitch by operating the wick upper and lower fine BfN node mechanism 20 and the selection mechanism, but the rack 23 has a plurality of teeth as shown in FIG. 5C. A difference is provided between the upper and lower limit positions of the tooth row groups (normal side tooth row group 23゛, moving side tooth row group 23'').First, the settings for each tooth row group 23'' and 23゛ are set. group 23°
The uppermost tooth 23a is set to the position where the wick 3 has been fully raised by the wick raising operation body 27 and the wick raising pinion 32, that is, the same position as when the wick up/down lever 6 is pushed down and set to the maximum combustion position. , the lowermost tooth 23''b is operated by operating the core lowering operating body 28 and the core lowering operating body 27 continuously from the position where the lamp wick 3 has been lowered completely to the uppermost tooth 23'a using the core lowering pinion 34. The setting is made within a range where the flame from the combustion tube 4 does not come out of the combustion appliance.

On the other hand, regarding the setting of the moving side tooth group 23', first set the lowermost tooth 23''b of the normal side tooth group 23'.
The wick 3 is set in the direction in which the wick 3 can be lowered further, that is, the minimum combustion position, and the uppermost tooth 23''a is set so that even if the wick raising operation body 27 is operated continuously in the same way, the standing flame from the combustion tube 4 will not combust. It is set within a range that does not go outside the equipment.

Therefore, in the same tooth row group, the centering operation body 2
Even if 7 is operated, the wick raising pinion 32 cannot advance the teeth of the rack 23 any further, and even if the wick 3 is raised, no abnormal flame will occur, allowing for safe combustion. You can finely adjust the amount. In addition, if you want to further reduce the combustion amount in the "normal position" with the select mechanism, you can narrow it down to the minimum combustion position by moving to any position or moving the lowermost tooth 23°b and then operating it to the "movement position". On the other hand, if you want to further increase the combustion amount in the "movement position", you can increase it to the maximum combustion position by moving the uppermost tooth 23"a and then operating it toward the "normal position".

Therefore, the "normal position" side in the above explanation is the top tooth at 23°.
a, both teeth 2 on the “movement position” side along with the lowermost tooth 23゛b
Since it is located higher than 3"a and 23"b, it can be promoted as a "warm course", and conversely, the "moving position" side can be promoted as a "low-key course", allowing you to select a course according to the size of the room and the season. At the same time, the combustion amount of this combustor ranges from the maximum combustion amount for the "warm course" to the minimum combustion amount for the "low-temperature course," making it possible to have a wider range of variation.

FIG. 8 shows an example of an oil combustor using the wick up-and-down device of this embodiment, and 43 is a door 4 attached to the base body 25.
4 is an ignition knob attached to the tip of the ignition lever 9;
Reference numeral 45 denotes 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 the door 43, select a course with the operating knob 31c inside, then press down the ignition knob 44 and wick up/down knob 45 to ignite the wick 3, and after confirming ignition. closes door 43. Once combustion has started and stabilized, the amount of combustion is normally adjusted using the core lowering operating body 28 and the core raising operating body 27 outside the R43. Therefore, in order to raise the wick 3 to the maximum combustion position in the "warm course" after operating the wick raising operating body 27 in the "warm course", it is necessary to open the door 43 and switch the operating knob 31c. There is 9
This time difference also makes it possible to suppress the continuation of the flare-up. Further, 31e is a course display provided on the selection operation body 31, and a display window 25 is provided outside the door 43 of the base body 25.
A is provided so that the location of the selected course can be confirmed from the outside by color.

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 upper/element fine adjustment mechanism in addition to the lead up/down mechanism to enable the lead up/down in small steps. After raising the wick for ignition, the combustion amount can be adjusted in small increments using the wick fine adjustment mechanism, and the combustion amount can be arbitrarily selected using the selection mechanism, and the combustion amount can be adjusted accordingly. By selecting a state in which the variable range can be widened and the upper limit of the fine adjustment range is low, it is possible to suppress the occurrence of standing flames, resulting in high safety.
