Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core lifting device for a wick type oil combustor.

2. Description of the Related Art Generally, in this type of oil combustor, the wick is moved up and down to burn and extinguish, and the vertical movement of the wick moves the pin 72 of the wick 71 to the upper and lower arms of the wick as shown in FIG. This is done by vertically moving the core up / down lever 76 of the core up / down mechanism 75, which is linked to the 73 and the core up / down arm 73 via the core up / down shaft 74. Further, recently, as shown in FIG. 9, the core upper / lower lever 76 is attached to the core upper / lower lever 76 and the pinion 79 incorporated in the operation base 78 side so that the core upper / lower lever 76 can be driven in small steps within the combustion range to adjust the heat power. You can see some of them. In the figure, 80 is a slide shaft that holds the pinion 79 rotatably and slides back and forth with respect to the operation base 78, 81 is a fine adjustment knob for raising that drives the pinion 79 via the slide shaft 80, and 82 is Fine adjustment knob for lowering the core that drives the pinion 79 via the slide shaft 80. 83 adjusts the positional relationship between the pinion 79 and the rack 77 to the normal dimension in the up / down and front / rear directions, and then the pinion 79 is integrated with the core up / down lever 76. A fixing screw, 84 is a rack shaft for supporting the rack 77 coaxially with the core up-down lever 76.

However, in the oil combustor having the above-described configuration, the rotary movements of the fine adjustment knob 81 for raising the core and the fine adjustment knob 82 for lowering the lead are once converted into linear movements by the slide shaft, and the pinion 79 is further added. In order to rotate, the movement direction conversion unit causes a twist and requires more operating force, or the weight of the wick adds weight, so the operating force of the fine core adjustment knob 81 for raising the core is the fine adjustment knob 82 for lowering the core. There was a problem that it was larger than the operating power.

The present invention has been made in view of the above circumstances, and an object thereof is to make motion transmission to the pinion smooth without twisting and to make the operating force of each operation button equal.

Means for Solving the Problems The present invention provides a vertically movable wick to achieve the above object,
A core up / down mechanism having a core up / down lever for vertically moving the wick, a vertically movable rack connected to the core up / down lever, a support for holding the rack vertically movable, and a contact with the rack. The pinion is rotatably and rotatably provided and drives the rack in small increments, and an operation button for operating the pinion.The pinion and the operation button are provided with a core raising and a core lowering respectively, and the rack is Dedicated teeth for raising and teeth for lowering are arranged, and the dimension from the center of rotation of the raising operation button to the operating portion is larger than the dimension from the center of rotation of the lowering operating button to the operating portion, or the above-mentioned rotation. The dimension from the center to the meshing portion of the descending pinion with the rack is made larger than the dimension from the same rotation center to the meshing portion with the rack of the ascending pinion.

Operation The present invention makes it possible to adjust the combustion amount by either the core up / down lever or the fine adjustment operation button with the above-mentioned configuration, and further, the movement of the motion to the pinion is smooth without twisting and each fine adjustment button is used. It is possible to make the operation power of the same and it is very easy to use.

Next, a manually operated core up / down mechanism 5 for vertically moving the wick 3
Will be described. First, reference numeral 6 is a core up / down lever for moving the wick 3 up and down. One end of the wick 3 is linked to the wick 3 through an appropriate linking means as described in the conventional example. The core up / down lever 6 is rotatably supported by a pin 8 on a core up / down base plate 7 in the middle thereof. 9 is the above-mentioned core up-down lever 6
With the ignition lever pivotally supported by the pin 8 on the upper and lower substrates, the ignition device (not shown) is operated by one end 9a of the ignition lever to ignite the wick 3. It is designed to return to the position. 10 is a pin 8 together with the core up-down lever 6 as well as the ignition lever 9.

37 is a core lowering pinion, which is pivotally supported by the pinion shaft 35 to the core lowering bearing 31 of the lower operation button 30.
It is urged toward the rack 21 by a peoion push spring 36 provided between the boss 30 and. The operation buttons 26 and 30 and the pinions 34 and 37 are the rotation center of the raising operation button 26, that is, the dimension L ₁ from the operation shaft 23 to the upper operation portion 26a is the rotation center of the lowering operation button 30. It is larger than the dimension L ₂ up to the lower operation part 30a, or the pinion for descending from the above rotation center.
The dimension l ₁ of the 37 up to the meshing portion with the rack 21 is set to be larger than the dimension l ₂ from the rotation center to the meshing portion of the lifting pinion 34 with the rack 21. Reference numeral 40 denotes an operation base body for mounting and fixing the integrated fine adjustment mechanism 20, which is integrally mounted on the upper and lower core substrates 7.

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

First, when the lead up / down lever 6 is pushed down from the state before use in FIG. 2, the wick 3 shown in FIG. 3 rises to the combustion position and the ignition position (not shown) is activated via the ignition lever 9, Ignite the wick 3. Then, the ignition lever 9 returns to the original state. At this time, the rack 21 of the fine adjustment mechanism 20 linked to the lead up / down lever 6 is also pushed down in the same manner, and faces the lead-up pinion 34 and the lead-down pinion 37. The core raising / ignition operation is completed as described above. When the combustion starts, the amount of combustion can be adjusted by the vertical movement of the core up / down lever 6, and the adjustment of the amount of combustion by operating the fine adjustment mechanism 20 will be described with reference to FIGS. 4 to 6. . First, when the wick 3 is set to the combustion position, the rack 21 is set to a position facing the core raising pinion 34 and the core lowering pinion 37 as shown in FIG. To reduce the amount of combustion, press the lower operation button 30
Operate in the Sa direction. As a result, the core lowering pinion 37 pivotally supported by the lower operation button 30 is engaged with the rack 21 which is normally in the non-coupling state, and is rotated in the direction of arrow D as it is.
21 will be pushed up in the direction of arrow E. As a result, the lead up / down lever 6 linked with the rack 21 is also pushed up in the direction of the arrow E, so that the wick 3 is lowered. At this time, when the lower operation button 30 is pressed once, the core lowering pinion 37 is set to have a dimensional relationship such that at least one tooth of the rack 21 is fed. When the centering pinion 37 finishes feeding one or more teeth of the rack 21, the lower operation button 30
Is returned to the original state shown in FIG. 4 by the urging force of the lower operation button spring 33 provided between the base body 22A of the support and the lower operation button 30, and the centering pinion 37 and the rack 21 are disengaged. Also, the core lowering pinion 37 is a pinion pushing spring.
Since 36 is always urged in the direction of arrow G, 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 upper operation button 26 may be operated. That is, as shown in FIG. 5, when the upper operation button 26 is operated in the direction of arrow Sb, the centering pinion 34 engages with the rack 21 which is normally in the non-coupling state and rotates in the direction of arrow H without any change. 21 will be pushed down in the direction of arrow J. As a result, the lead up / down lever 6 linked to the rack 21 is also pushed down in the direction of arrow J, and the lead light 3 is raised. At this time, as in the case of lowering the core, when the upper operation button 26 is pressed once, the core raising pinion 34 is set to have a dimensional relationship such that at least one tooth of the rack 21 is fed. Rack-up pinion 34 rack 21
When one or more teeth have been fed, the upper operation button 26 returns to the original state shown in FIG. 4 by the urging force of the upper operation button spring 29, and the engagement between the centering pinion 34 and the rack 21 is disengaged.
Further, the center-raising pinion 34 returns to its original state because the pinion pushing spring 36 is constantly biased in the direction of arrow G.

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 fine adjustment mechanism 20, and the rack 21 and the core of the fine adjustment mechanism 20 linked to the core up / down mechanism 5 can be adjusted. Since the raising pinion 34 and the core lowering pinion 37 are normally in a non-linked state, the wick 3 can be freely lowered by the core up-down mechanism 5 to extinguish the fire.

Further, in this core up / down device, the rotational movement of each operation button 26, 30 is transmitted to each pinion 34, 37 as it is, and the pinion 34, 37 is caused to perform the rotational movement. Can be transmitted to each pinion 34, 37 without waste, and at the same time, no kojirika occurs. Moreover, the dimension L ₁ from the rotation center of the raising operation button 26 to the upper operation portion 26a is larger than the dimension L ₂ from the rotation center of the lowering operation button 30 to the lower operation portion 30a, or from the rotation center. The dimension l ₁ from the descending pinion 37 to the meshing part with the rack 21 is the rack of the ascending pinion 34 from the center of rotation.
Since it is set to be larger than the dimension l ₂ up to the meshing portion with 21, the operating force of each operation button 26, 30 can be made equal by the lever principle. That is, the raising operation button 26
When you press, the weight of the wick is added and it becomes heavy,
This can be reduced by the lever principle so that the operating force can be made substantially equal to the pushing force of the lowering operation button 30.

FIG. 7 shows an example of an oil combustor using the core lifting device of this embodiment. 41 is a door attached to the operation base body 40, and 42 is an ignition knob attached to the tip of the ignition lever 9. , 43 are core up-down knobs 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 down the ignition knob 42 and the core upper and lower knobs 43 inside the door 41 to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the upper operation. The amount of combustion is adjusted with the button 26 and the lower operation button 30.

In the above embodiment, the operation button has been described as the upper operation button and the lower operation button as separate parts, but the same effect can be obtained even if these are integrated.

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 fine adjustment mechanism in addition to the core up / down mechanism so that the core can be moved up and down in small steps. The fine adjustment mechanism can be used to adjust the combustion amount in small increments after the core has been adjusted up and down or a large amount of combustion has been adjusted to extinguish the fire, and the series of operations of the fine adjustment mechanism can be smoothed and the operation of each operation button can be achieved. It is easy to use because it can equalize the power.
