Description

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 In general, this type of oil burner burns and extinguishes fire by moving the wick up and down, and the up and down movement of the wick is controlled by moving the pin 72 of the wick 71 into the wick upper and lower arms, as shown in Figure 9. 7
3, and a core up/down lever 76 of a core up/down mechanism 75 linked to this core up/down arm 73 via a core up/down shaft 74 is moved up and down. Recently, as shown in FIG. 10, a rack 77 attached to the core up/down lever 76, a rack 77 built into the operation base 78 side, and a rack 77 built into the operation base 78 side are connected to each other and rotated. Some devices have a fine adjustment mechanism in which a movable pinion 79 drives the core up/down lever 76 in small increments, making it easy to adjust the firepower within the combustion range. In addition, 80 in the figure is an operation base 78 that rotatably holds the pinion 79.
82 is a fine adjustment knob that drives the pinion 79 via the slide shaft 80; 83 is a fixing screw that integrates the rack 77 with the core up/down lever 76; 84 is a rank 77; This is a rank shaft for coaxially supporting the core up/down lever 76.

Problems to be Solved by the Invention However, the oil combustor with the above configuration does not have the @adjustment knob 8.
A slide shaft 80 is required between the pinion 79 and the pinion 79 to transmit the pushing force of the fine adjustment knob 82 to the pinion 79, resulting in a complicated and large-sized structure.

Therefore, the applicant devised a fine adjustment mechanism that eliminates the slide shaft by pushing the operation button in the horizontal direction to directly drive the pinion. However, this JAFM has a problem in that when the fine adjustment button is pushed in the horizontal direction, the opposite side protrudes beyond the front surface of the main body, which seriously spoils the appearance.

The present invention has been made in view of these points, and is an attempt to simplify the configuration and prevent the opposite side from protruding from the front surface of the main body even if the operation button is pressed horizontally.

Means for Solving the Problems In order to achieve the above object, the present invention provides a lamp wick that is vertically movable;
A wick up and down mechanism having a wick up and down lever that moves the wick up and down, a vertically movable rack connected to the wick up and down lever, a support that holds this rack so that it can move up and down, and a rack that drives the rack. It consists of a pinion for raising and lowering the core, which is rotatable toward and away from the core, and an operation button for operating both pinions, and the operation button has a substantially central portion that is rotated by the support. In addition to being freely pivotable, the pinion is provided on both end sides of the pivot portion as a boundary, so that the pinion can be fully utilized by pushing the both ends. The structure is divided into two independent parts. Also,
The support body exposes the operation button on the outer surface side of the operation base, and the operation button is in contact with the operation base or the support body at appropriate places on both ends of the operation button to prevent the operation button from protruding from the front surface of the main body. It has a structure with a protruding piece.

According to the present invention, with the above structure, the fuel weight can be reduced by 1A by either the core up/down mechanism or the fine adjustment mechanism, and the structure can be simplified by eliminating the slide shaft. Further, even if the operation button is pressed in the horizontal direction, the opposite side can be prevented from protruding from the front surface of the main body.

EXAMPLES The following examples will be explained with reference to FIGS. 1 to 7. First, in Figures 1 to 3, ■ is a core guide tube, 2 is a core outer tube arranged with a gap around the outer periphery of the core guide tube l, and 3 is a core outer tube arranged between the core guide tube l and the core outer tube 2. A lamp wick that can be moved up and down between 4
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.
I will explain about it. First, reference numeral 6 denotes an on-wick lever for moving the lamp wick 3 up and down, and one end thereof is connected to the lamp wick 3 via a suitable linking means.

The core upper and lower lever 6 is rotatably supported on the core upper and lower substrate 7 by a pin 8 in the middle thereof. Reference numeral 9 denotes an ignition lever which is pivotally supported on the wick upper and lower substrate 7 by a pin 8 together with the wick upper and lower lever 6, and whose one end 9a operates an ignition device (not shown) to ignite the lamp wick 3.
After ignition, it automatically returns to its original position. Numeral 10 is a core upper and lower board 7 which, like the ignition lever 9, is pivoted together with the core upper and lower lever 6 by a pin 8 to the core upper and lower board 7, and is adapted to be linked with the core upper and lower lever 6 by appropriate means. A spring 11 biases the wick upper and lower plates 10 toward the upper position (wick lowering value W), and is hooked between the ends of the wick upper and lower plates IO and the wick upper and lower substrates 7. Reference numeral 12 designates a locking plate that holds the wick upper and lower plates 10 at a lower position (wick raised position), and is rotatably supported by a pin 12a. This lock plate 12 has a long hole 14 through which a pin 13 implanted in the core upper and lower plates 10 is inserted, and a locking portion 14a is formed at the end of the long hole 14 to lock the pin 13. It looks like this.

That is, when the wick up/down lever 6 is pushed down (in the wick upward direction), the wick up/down plate 10, which is linked to the wick up/down lever 6 by appropriate means, rotates downward (the pin 13 of the wick up/down plate 10 is inserted into the elongated hole 14). when the pin 13 fits into the locking portion 14a and the core upper and lower plates 1 are held at that position despite the biasing force of the spring 11.
It will lock 0.

15 is a temporary spring attached to the lock plate 12, and 16 is a vibration extinguishing weight linked to this temporary spring 15 via a chain 17, which is erected above the pedestal provided on the core upper and lower substrates 7. be.

This weight 16 slides when an earthquake occurs and rotates the leaf spring 15, that is, the lock plate 12 via the chain 17.

As a result, the pin 13 is disengaged from the locking portion 14a of the elongated hole 14, and the core upper and lower plates 10 are rotated upward by the urging force of the spring 11. At this time, since the wick upper and lower plates 10 are linked with the wick up and down lever 6, the wick up and down lever 6 also rotates upward, and the lamp wick 3 is lowered to extinguish the fire.

At this time, the pin 13 that has returned to the upper position presses the temporary spring 15 and pulls the chain 17, returning the fallen weight 16 to its original state. 19 is the emergency button 2, extinguishing button, and the lock plate 12
The lock plate 12 is formed integrally with the weight 16.
It is designed to rotate.

Next, the fine adjustment mechanism 20, which is a feature of the present invention, will be explained using FIGS. 1, 4, 5, and 6. First, reference numeral 21 denotes a vertically movable rack, one end of which is linked to the core vertical lever 6 by suitable means. Reference numeral 22 denotes a support body, which is composed of a base body 22A and a lid body 22B, and has a shape that guides the side surface and the front and back direction of the rack 21.
5 and are integrated. Reference numeral 26 designates a rotatable upper operating button with a protruding piece 26a, which has a centering bearing 27, and the bearing provided at the lower part is pivotally supported on the operating shaft 23, and is connected to the base of the support body. It is biased in a direction away from the rack 21 by an upper operation button spring 29 provided between the rack 22 and the upper operation button spring 29 . Reference numeral 30 designates a rotatable lower operation button with a protrusion 30a, which has a centering bearing 31, and the bearing provided at the upper part is pivoted to the operation shaft 23 at a portion 32, and is connected to the base body 22 of the support body. It is biased in a direction away from the rack 21 by a lower operation button spring 33 provided between the rack 21 and the lower operation button spring 33. 34 is a centering pinion, which is pivotally supported by a pinion shaft 35 to a centering bearing 27 of the upper operation button 26;
A pinion push spring 36 provided between the upper operation button 26
The force is applied toward the rack 21.

37 is a center lowering pinion, which is pivotally supported by a pinion shaft 35 to a center lowering bearing 31 of the lower operation button 30, and is biased toward the rack 21 by a pinion pushing spring 36 provided between it and the lower operation button 30. be. In other words, fine adjustment mechanism 2
0 includes the rack 21, the support body 22, and the upper operation button 26
and a lower operation button unit 38 consisting of a centering pinion 34, a pinion shaft 35, and a pinion push spring 36, a lower operation button unit 3 consisting of a lower operation button 30, a center lowering pinion 37, and a pinion shaft 35 and a pinion push spring 36.
9, upper operation button spring 29, and lower operation button spring 33
It has a structure in which it is attached in one piece.

Reference numeral 40 denotes an operation base to which the integrated fine adjustment mechanism 20 is attached and fixed, and is integrally attached to the core upper and lower substrates 7.

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

First, when the wick up/down lever 6 is pushed down from the pre-use state shown in FIG. 2, the wick 3 rises to the combustion position as shown in FIG. 3, and the ignition device (not shown) is activated via the ignition lever 9. , ignites the lamp wick 3. The ignition lever 9 then returns to its original state. At this time, the rack 21 of the fine adjustment mechanism 20 linked to the wick up/down lever 6 is similarly pushed down and comes to oppose the wick raising pinion 34 and the wick lowering pinion 37.The wick raising and ignition operations are completed in a manner greater than 0. do.

Once combustion starts, the amount of combustion can be adjusted by moving the wick up and down lever 6 up and down, but the adjustment of the amount of combustion by operating the fine adjustment mechanism 20 will be explained with reference to FIGS. 4 to 6. . First, when the lamp wick 3 is set to the combustion position, the rack 21 is moved by the wick raising pinion 34 as shown in FIG.
and the core lowering pinion 37. When reducing the combustion amount, the lower operation button 30 is operated in the direction of the arrow Sa as shown in FIG. The rack 21 is engaged with and rotates in the direction of the arrow E, thereby pushing the rack 21 up in the direction of the arrow E. As a result, the wick up/down lever 6 linked to the rack 21 is also pushed up in the direction of arrow E, and the wick 3 is therefore lowered.

At this time, the core lowering pinion 37 is set in a dimensional relationship such that when the lower operation button 30 is pressed once, the core lowering pinion 37 advances at least one tooth of the rack 21. When the core lowering pinion 37 finishes feeding one or more teeth of the rack 21, the lower operation button 30 is moved to the fourth position by the biasing force of the lower operation button spring 33 provided between the base body 22 of the support body and the lower operation button 30. The state returns to the original state shown in the figure, and the core lowering pinion 37 and the rack 21 are disengaged from each other. In addition, the wick lowering pinion 37 returns to its original state because the pinion pushing spring 36 is always biased in the direction of arrow G. The wick 3 is lowered little by little by operations such as 0 or more, and the combustion amount is gradually reduced. You can narrow it down.

Next, if you want to increase the combustion amount, you can operate the upper operation button 26. That is, as shown in FIG. It engages with the uncoupled rack 21 and rotates in the direction of arrow H, pushing down the rack 21 in the direction of arrow J. As a result, the rack 21
The wick up/down lever 6 linked to the wick will also be pushed down in the direction of arrow J, and the wick 3 will therefore rise. At this time, the dimensions of the centering pinion 34 are such that when the upper operation button 26 is pressed once, as in the case of lowering the centering, the centering pinion 34 advances at least one tooth of the rack 21. When the centering pinion 34 finishes feeding one or more teeth of the rack 21,
The upper operation button 26 returns to its original state as shown in FIG. The engagement will come off. Further, the centering pinion 34 returns to its original state because the pinion pushing spring 36 is always biased in the direction of arrow G.

Here, this core up and down device has up and down operation buttons 26 and 30.
are formed separately and their ends are used as the support body 22, so even if the upper and lower operation buttons 26 and 30 are pressed, the operation button on the opposite side is not released, as is clear from FIGS. 5 and 6. There will be no protrusion in the direction. Moreover, in this embodiment, the protrusions 26a, 30a are provided on each of the operation buttons 26, 30.
Since it is located inside the operation base 40 provided with
Even if when one operation button 26 is pressed, the other operation button 30 tries to rotate outward due to the frictional force of the shaft support, the protruding piece 30a abuts the inner surface of the operation base 40, so it cannot rotate outward any further. The operation buttons 26 and 30 can be prevented from protruding more reliably.

In addition, FIG. 8 shows an example of an oil combustor using the wick up-and-down device of this embodiment, and numeral 41 is a door attached to the operation base body 40, and 42 is a door attached to the tip of the ignition lever 9. The ignition knob 43 is a wick up/down knob attached to the tip of the wick up/down lever 6. The user's operating procedure is to first open the door 41 and push down the ignition knob 42 and wick top and bottom knobs 43 located inside to light the wick 3, and when combustion begins, press the wick top and bottom knobs 43 or the top operation button. 26 and the lower operation button 30 to adjust the combustion amount.

More than the effects of the invention, as is clear from the description of the embodiments, the lead up/down device of the present invention uses a fine adjustment mechanism in addition to the lead up/down mechanism to allow the lead up/down in small steps.・After raising and lowering the wick for extinguishing a fire or setting a large combustion rate of 11 sections, the combustion rate can be adjusted in small increments using the fine 11i 1 section mechanism, and the structure is such that the opposite side does not protrude from the front of the main unit when the operation button is pressed horizontally. In addition, it is possible to reduce the number of parts and simplify the structure.
