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

Conventional technology In general, this type of oil combustor burns by moving the wick up and down.
The fire is extinguished, and the vertical movement of the wick is performed by vertically moving a lever 63 linked to the wick 61 via a pin 62, as shown in FIG. In the figure, 64 is the pivot of the lever 63, and 65
Is a fuel tank, 66 is a core guide cylinder, 67 is a core outer cylinder, and 68 is a combustion cylinder.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the petroleum combustor configured as described above, the stove body has been downsized recently, and accordingly, the distance from the pivot point 64 of the lever 63 becomes short, and the lever 63 is slightly operated. Therefore, the wick 61 moves greatly, and it is very difficult to make fine adjustment when the user tries to adjust the combustion amount a little, and the degree of combustion adjustment has to be judged by the position of the lever 63, which is not convenient. There was a point.

The present invention has been made in view of the above circumstances, and it is possible to easily perform fine adjustment of the combustion amount and to provide an indicator according to the fine adjustment movement so that the adjustment degree can be immediately determined. It is intended.

Means for Solving the Problems In order to achieve the above object, the present invention provides a core up / down lever for vertically moving a lamp core, a core up / down fine adjustment mechanism for driving the core up / down lever within a predetermined combustion adjustment range, and The core up / down fine adjustment mechanism is normally in a state of non-coordination with the core up / down lever and is provided with a display lever which is operated by movement of the core up / down lever and a display body which is moved by movement of the display lever. The display body is linked to the lever so as to drive it, and when the display body is driven to the center lowering side end within the range adjustable by the fine core fine adjustment mechanism, The display is linked with the display lever so that the display remains on the lower side of the display window.

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 core up-down adjustment mechanism can be used to finely adjust the combustion amount, and the degree of adjustment can be accurately determined by the display, which is convenient.

Example An example will be described below with reference to FIGS. 1 to 8.

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. 8) 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 by the pin upper and lower base plate 7 together with the core upper and lower lever 6 by one end 9a of the ignition lever (not shown) to activate the wick 3. After operation, it automatically returns to its original position. 10

Next, referring to FIG. 1 and FIG. 6, a combustion amount display mechanism 41 provided on the opposite side of the above-described core up / down mechanism 5 and core up / down fine adjustment mechanism 20.
Will be explained. Reference numeral 6a denotes an operation arm formed on the core up-and-down lever 6, which opens and closes a micro switch 42 for controlling energization of, for example, an electronic odor absorber (not shown). Reference numeral 43 denotes a display lever rotatably supported on the back surface of the base body 25. One end of the display lever is arranged so as to face the lower end of the operation arm 6a of the core up / down lever 6, and the other end is vertically moved outside the guide plate 44. It is engaged 45a with the moving display body 45. In the figure, 46 is a spring for urging the display body 45 downward, and 47 is a display window provided in the base body 25.

Next, the operation of the core lifting device for an 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 FIGS. 1, 3 and 7C, the wick 3 is moved as shown in FIG.
Rises to the maximum combustion position 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 auxiliary lever 2 integrally attached to the core up-down lever 6
1 also performs the same rotational movement as the core up / down lever 6, and the rack 23 attached to the auxiliary lever 21 faces the core up / down pinions 32, 34 of the core up / down fine adjustment mechanism 20.

Further, at this time, as shown in FIG. 7A, the operation arm 6a abuts on the abutment portion 43a of the display lever 43 and rotates the abutment portion 43a,
The display body 45 rises to the full extent of the display window 47 and indicates that the combustion amount is maximum.

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 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.

When reducing the combustion amount, as shown in FIG.
5 is operated in the direction of the arrow Sa, the contact piece 28b pushes the projecting piece 30a of the core lowering slide body 30, and the core lowering slide body 30 becomes the base body 2.
5 slides inside the bearing 31b like Fa, and the core lowering pinion 34 pivotally supported by the core lowering slide body 30 is engaged with the rack 23 which is normally in the non-coupling state, and is in the direction of arrow D as it is. Then, the rack 23 is rotated in the direction of arrow E and pushed up in the direction of arrow E. 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, the operation body 28 for core lowering
When pushed twice, the core lowering pinion 34 has such a dimensional relationship that only one tooth of the rack 23 is fed. Core down pinion 3
When 4 has finished feeding one tooth of the rack 23, the core lowering slide body 34 is returned to the original state shown in FIG. 5A by the urging force of the core lowering slide return spring 38 which is engaged with the support shaft 35. With returning, the operation body 28 for lowering the core also returns to the original state,
The centering pinion 34 and the rack 23 are disengaged from each other.
Further, the core lowering pinion 34 is a core lowering pinion return spring 40.
Is always urged in the direction of arrow G to return to the original state. 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.

The final operation in the above operation, that is, the position of the lowermost tooth 23a of the rack 23 is set to a position where the core lowering pinion 34 cannot feed the teeth of the rack 23 below the height at which the wick 3 can normally burn. .

The operation of the display mechanism 41 associated with the fine adjustment of the core lowering is as shown in FIG. 7B.
While a is pushed up in the direction of arrow E, the display lever 43 rotates in the direction opposite to the above-mentioned center raising / ignition operation, and the display body 45 descends to display the combustion amount at that time. Further, the display unit 45 repeats the core lowering fine adjustment several times to leave a part of the display in the display window 47 at the time when the core lowering pinion 34 finishes feeding the lowermost teeth 23a of the rack 23, that is, at the minimum core height. Thus, the position of the lowermost tooth 23a of the rack 23 is set. Therefore, the display body 45 is displayed on the display window 47.
It is usually invisible when the fire is extinguished with the emergency fire extinguishing button 19 as shown in FIG. 7C, or when the wick 3 is lowered to the normal combustion height or lower with the wick up / down lever 6. .

Next, when the combustion amount is to be increased, the centering operation body 27 may be operated as shown by the arrow Sa as shown in FIG. 5B. When pushed twice, the centering pinion 32 sends only one tooth of the rack 23.

The operation of the display mechanism 41 associated with the fine adjustment of the lead-up is similar to that of the lead-up / ignition operation, as shown in FIG. 7A, the lead up / down lever 6 and the operation arm 6a are pushed down in the direction of arrow J. , The display lever 43 is rotated to rotate the display body 4.
5 is raised and the amount of combustion at that time is displayed. When the lead-up pinion 32 finishes sending the uppermost teeth 23b of the rack 23 after repeating the lead-up fine adjustment several times, the wick 3 is raised to the maximum combustion position and the display body 45 is raised to fill the display window and burned. It is set to indicate the maximum amount.

As described above, in this combustor, the manually operated core up-and-down mechanism 5 for vertically moving the wick 3 and the core up-and-down mechanism 5 are normally in a non-linked state, and are engaged with the core up-and-down mechanism 5 during operation. The core fine adjustment mechanism 20 which is driven in small steps and the combustion amount display mechanism 41 which is interlocked with the core vertical mechanism 5 make it possible to easily adjust the combustion amount little by little and to judge the degree of adjustment by the display body 45.

FIG. 8 shows an example of an oil combustor using the core lifting device of the present embodiment. 51 is a door attached to the base body 25, 52 is an ignition knob attached to the tip of the ignition lever 9, and 53 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, the door 51 is opened, and the ignition knob 52 and the core upper and lower knobs 53 located inside the door 51 are pushed up to ignite the wick 3, and the door 51 is opened.
Close. When the combustion starts and becomes stable, the display body 45 is normally operated by the core lowering operation body 28 and the center raising operation body 27 outside the door 51.
The amount of combustion is adjusted while watching. Reference numeral 54 is a fire extinguishing operation body that is also connected to the emergency fire extinguishing button 19 provided outside the door 51.

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 and the core up / down fine adjustment mechanism so that the core up / down adjustment can be performed delicately. After adjusting the top and bottom of the core for burning and extinguishing the fire with a mechanism and adjusting the amount of combustion extensively, you can finely adjust the amount of combustion with the fine adjustment mechanism for the center of the core. 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 adjustment range of the combustion amount. By becoming able to know it, the usability is dramatically improved. Further, since the display mechanism associated with the adjustment movement of the combustion amount is provided, the degree of adjustment of the combustion amount can be determined, which is convenient. In particular, the above display is set so that the display is left even at the minimum core height due to the fine adjustment operation, so even if the red heat of the combustion cylinder is temporarily darkened when the fire is extinguished with continuous fine adjustment of centering It can be seen at a glance that the normal combustion state has been set by the displayed body. 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.
