Description

  The present invention relates to a core lifting device for a core lifting oil combustor.

  There is known a core up-down type oil combustor in which a combustion cylinder is arranged above an oil tank, and fuel in the oil tank is supplied to the lower part of the combustion cylinder using a core. Adjustment of the combustion amount of this oil combustor and The fire is extinguished by the vertical movement of the core rotated by the operation unit.

  As a general configuration of this core lifting device, there are a dial type and a lever type, and the dial type core lifting device includes a rack gear attached to the core holder and a pinion gear provided at the inner end of the core vertical shaft. There is one that moves the core up and down by meshing (see Patent Document 1). On the other hand, the lever-type core lifting device is provided with a pair of engaging pins on the core, and the tip of the substantially U-shaped driving lever is engaged with the engaging pin, and the driving lever fixed to the core vertical shaft is rotated. There are those that move the core up and down (see Patent Document 2).

  In recent oil combustors, the development of a combustion section that does not easily cause incomplete combustion even when the amount of combustion is reduced has progressed, and it has become possible to perform combustion at a desired amount of combustion by adjusting the core height. It was. For this reason, when the temperature or heating power desired by the user during combustion is reached, the heating power can be adjusted within the adjustment range of the combustion amount by operating the vertical axis of the core.

  The dial type core lifting device reduces the pitch of the pinion gear and rack gear so that the amount of rotation of the core vertical axis between the center lowering position and the center raising position is set to a large value of nearly one rotation. The core moves slowly with respect to the movement, making it easy to adjust the amount of combustion.

On the other hand, the lever-type core lifting device has a narrow pivot angle of the core vertical axis between the center lowered position and the center raised position, and the core vertical axis is directly rotated by the operation lever. Since the core height greatly changes with the movement, it is difficult to manually adjust the combustion amount in accordance with the combustion state in which the maximum heat generation amount is reduced. For this reason, the core vertical axis is not directly rotated by the operation lever, but parts are added between the operation lever and the core vertical axis so that the core moves slowly relative to the operation lever drive at the core position during combustion. Thus, it is easy to adjust the combustion amount (see Patent Document 3).

  The dial-type core lifting device is easy to adjust the amount of combustion, but the operation is troublesome because it is necessary to operate a large number of operation knobs during normal core lifting operation. In addition, if the pitch between the pinion gear and the rack gear is made fine, it becomes difficult to process, and the pinion gear and the rack gear require dimensional accuracy in order to obtain an accurate core height. .

  In addition, when replacing the lead, the pinion gear and the rack gear are disengaged and the lead is pulled upward, so it is necessary to accurately align the meshing position of the rack gear and the pinion gear after the lead is replaced. There was a shortcoming that took time.

  On the other hand, the lever-type core lifting device has a narrow rotation angle of the core vertical axis between the center-lowering position and the center-raising position, so it is difficult to adjust the core height using the operating lever. In order to make it easy to perform, parts for adjusting the combustion amount are indispensable as in Patent Document 3, and the number of parts increases.

  In addition, the lever-type core lifting device is an engagement between the engagement pin and the drive lever, so the core replacement work can be performed relatively easily, but the core vertical axis and the drive lever for moving the core up and down are large in shape, Numerous parts exist in a narrow space for mounting the core to the oil tank, complicating the structure of the core.

  In this way, even the core up and down type oil combustor can adjust the combustion amount and the convenience is improved, but the manufacturing cost rises because the number of parts is increased and the structure of the core lifting device is complicated. . The present invention proposes a core lifting device that has a simple structure and can easily adjust the amount of combustion and replace the core.

The present invention solves the above-mentioned problem, and the core inner cylinder 3 standing from the bottom plate of the oil tank 2, the core outer cylinder 4 attached to the upper surface plate of the oil tank 2, and the core inner cylinder 3 are movable up and down. a core 5 mounted on, provided the core vertical shaft 1 which moves up and down the core 5, the mounting of the drive plate 6 movable around a core vertical shaft 1 to the inner end of the core vertical shaft 1, the drive A drive pin 6 a is formed from the movable end of the plate 6 toward the core 5, and an engaging portion 8 that engages the drive pin 6 a of the drive plate 6 on the side surface of the core holder 7 attached to the outer periphery of the core 5. In the oil combustor in which the drive pin 6a of the drive plate 6 movable by the rotation of the core vertical shaft 1 drives the core holder 7 to move the core 5 up and down, the engaging portion 8 of the core holder 7 has a core. 5 is formed by a horizontally long slot 8a along the circumferential direction, and the width A of the slot 8a is driven by a drive plate 6 that is movable around the core vertical axis 1. Also the in which you characterized in that it is longer than the lateral direction of the movable range B of emissions 6a.

For this reason, the rotation range of the core vertical axis 1 between the core lowering position and the center raising position can be reduced, and the core vertical operation can be simplified. At the center raising position, the core 5 is slowly moved with respect to the rotation of the core vertical axis 1. Because it moves, the amount of combustion can be easily adjusted. Further, the drive pin 6a of the drive plate 6 does not come into contact with the side end portion of the long hole 8a of the engaging portion 8 when the core vertical shaft 1 is rotated, and the core 5 does not rotate along the core inner cylinder 3. Therefore, the core up and down operation can be performed smoothly.

The core vertical shaft 1 is disposed at a position deviated from the center of the core inner cylinder 3, and is engaged with the drive pin 6a in the movable range B of the drive pin 6a of the drive plate 6 from the extinguishing position of the core 5 to the maximum combustion position. When the engagement with the joint portion 8 is maintained and the drive pin 6a is disengaged from the engagement portion 8 when it is rotated in the center raising direction from the maximum combustion position, the lead holder 7 is pulled out together with the lead 5. As a result, the core 5 can be easily pulled out by simply rotating the core vertical axis 1 in the core raising direction, and the height relationship between the drive pin 6a and the engaging portion 8 is constant. There is no need to adjust the core height after replacement, and the core replacement work can be facilitated.

  In the present invention, the drive pin 6a of the drive plate 6 attached to the inner end of the core vertical shaft 1 is engaged with the engaging portion 8 of the core holder 7 attached to the outer periphery of the core 5, so that the core vertical shaft 1 is The core 5 integrated with the core holder 7 is moved up and down along the core inner cylinder 3 by the drive pin 6a of the drive plate 6 movable at the time of rotation, and the core vertical axis between the center lowered position and the center raised position. The rotation range of 1 can be narrowed, and the core up / down operation can be easily performed.

  Further, since the drive pin 6a of the drive plate 6 is configured to rotate around the core vertical axis 1, the amount of movement in the vertical direction decreases as it approaches the center raising position, and the core vertical axis 1 at the core height during combustion. Since the core 5 moves slowly with respect to the rotation of the core, it is easy to adjust the combustion amount even if the rotation range of the core vertical shaft 1 is narrow, and the core lifting device is easy to operate and easy to adjust the combustion amount It became possible.

  In this way, even if the pivot range of the core vertical shaft 1 is narrow, the combustion amount can be adjusted by the configuration in which the core vertical shaft 1 is directly rotated. The number of components arranged in the tank 2 can be reduced and the size can be reduced, the number of components can be reduced, and the structure can be realized with a simple structure. Thus, the manufacturing cost can be reduced.

  Further, the engaging portion 8 is constituted by a horizontally long slot 8 a along the circumferential direction of the core 5, and the lateral width dimension A of the slot 8 a is within the movable range B of the drive pin 6 a that is movable around the core vertical axis 1. Since it is set so as not to contact the side end portion of the long hole 8a, the core 5 can move in the vertical direction along the core inner cylinder 3 without rotating when the core vertical shaft 1 is rotated. 1 can be rotated by a light operation.

  Further, when the core vertical shaft 1 is disposed at a position laterally deviated from the center position of the core inner cylinder 3, the drive pin 6a and the engagement portion 8 are engaged when rotated in the center raising direction from the maximum combustion position. Since the core 5 can be easily removed simply by rotating the core vertical shaft 1 and the core 5 is returned after the replacement of the core 5, the drive pin 6a of the drive plate 6 and the engaging portion 8 can be removed. Since the lead height is determined by the engagement with the lead, it is not necessary to adjust the lead height, and the lead replacement work can be easily performed.

  The present invention will be described with reference to the embodiments shown in the drawings. Reference numeral 2 is an oil tank of an oil combustor, 3 is a core cylinder standing upright from the bottom of the oil tank 2, and 4 is detachably attached to the top plate of the oil tank 2. The core outer cylinder 5 is a core attached to the core inner cylinder 3 so as to be movable up and down. The fuel in the oil tank 2 is sucked up by the lower end of the core 5 and supplied to the upper end of the core 5.

  The present invention relates to a dial-type core lifting device, wherein 1 is a core vertical shaft that is inserted from the outside of the oil tank 2 to perform the core vertical operation, 9 is a combustion cylinder disposed above the core 5, 1a is An operation knob that is attached to the outer end of the core vertical shaft 1 and rotates the core vertical shaft 1. The operation knob 1 a rotates the core vertical shaft 1 in the upward direction so that the upper end of the core 5 is attached to the combustion cylinder 9. When the fuel is sucked down by an ignition device (not shown), the fuel sucked up at the lower end of the wick 5 is burned at the upper end of the wick 5, and the generated combustion flame and combustion gas are supplied with air in the combustion cylinder 9 and burned. To complete.

  Reference numeral 10 denotes a rotating plate that is interlocked with the core vertical shaft 1, 11 is a return spring attached to the core vertical shaft 1, and 12 is a stopper that engages with the rotating plate 10 at the center raising position. When rotating in the direction, the return spring 11 is wound up, and the rotation plate 10 and the stopper 12 engage with each other at the maximum combustion position to accumulate power in the return spring 11.

  Reference numeral 13 denotes a vibration sensor connected to the stopper 12. The vibration sensor 13 urges the stopper 12 in the engaging direction. When the vibration weight constituting the vibration sensor 13 falls down with a predetermined vibration value, the vibration damper 13 stops. 12 and the rotating plate 10 are disengaged, and the core vertical shaft 1 is rotated in the core lowering direction by the force of the return spring 11 to extinguish the oil combustor.

  By the way, recently, the development of combustion parts that are difficult to cause incomplete combustion even if the amount of combustion is reduced is progressing, and the number of parts that can adjust the amount of combustion is increasing, and by adjusting the core height, combustion can be performed at the desired amount of combustion. Although it is possible to adjust the combustion amount when the core height changes greatly with respect to the rotation of the core vertical axis 1, it is difficult to adjust the combustion amount. In the position, it is necessary to move the core 5 slowly with respect to the rotation of the core vertical axis 1.

  For this reason, the conventional dial type core lifting device makes it easy to adjust the combustion amount by finely setting the pitch of the pinion gear and the rack gear. In this case, however, a large number of operation knobs 1a must be operated. Therefore, there is a drawback that a normal core up / down operation is troublesome. Further, it takes time to process the pinion gear and the rack gear, and the processing cost also increases.

  On the other hand, although the lever-type core lifting device has good operability, it is difficult to adjust the combustion amount because the pivot angle of the core vertical shaft 1 between the center lowering position and the center lifting position is narrow, and it is easy to adjust the combustion amount. Then, there is a disadvantage that the number of parts increases and the structure becomes complicated, and the one that can adjust the combustion amount with the core up and down type oil combustor has problems such as reduction in manufacturing cost and improvement in operability, and it is still improved There was still room for.

  The present invention proposes a core lifting device which solves the above-mentioned problems and has a simple structure and is easy to operate. Reference numeral 6 denotes a drive which is movable around a core vertical shaft 1 provided at the inner end of the core vertical shaft 1. The plate 6a is a drive pin provided at the movable end of the drive plate 6. The drive pin 6a extends from the drive plate 6 toward the core 5 side.

  Reference numeral 7 denotes a core holder attached to the outer periphery of the core 5, and 8 denotes an engaging portion attached to the core holder 7, which engages with the drive pin 6 a of the drive plate 6. The engaging portion 8 of the embodiment shown in the figure is constituted by a horizontally long slot 8a along the circumferential direction of the core 5. When the driving plate 6 is moved by rotating the core vertical shaft 1, the driving pin 6a is moved. The core 5 integrated with the core holder 7 moves up and down along the core inner cylinder 3 by rotating about the core vertical axis 1 and applying a force to the engaging portion 8 with which the drive pin 6a of the drive plate 6 is engaged. Move.

  The height of the core 5 coincides with the height of the drive pin 6a of the drive plate 6 that rotates about the core vertical axis 1, and the drive plate 6 is driven when the core vertical axis 1 is rotated to the core lowered position. The pin 6a is located near the bottom dead center, and at this time, the core height is the lowest. When the core vertical shaft 1 is rotated to the center raising position, the drive pin 6a is located near the top dead center, and the core height is the highest. For this reason, the amount of rotation of the core vertical shaft 1 between the core lowering position and the center raising position can be set to half or less, and there is no need to operate many operation knobs 1a. A core lifting device that does not bother up and down operation can be constructed.

  Further, since the drive pin 6a of the drive plate 6 is configured to rotate around the core vertical axis 1, the amount of movement in the vertical direction decreases as it approaches the top dead center. The movement of the core 5 with respect to the rotation is reduced. For this reason, within the adjustment range of the wick 5 that reduces the combustion amount from the maximum combustion position, the wick 5 moves slowly with respect to the rotation of the wick vertical shaft 1 so that the combustion amount can be easily adjusted. It is.

  Thus, even if the rotation range of the core vertical shaft 1 is narrow, the core 5 moves slowly at the core position during combustion. Therefore, the combustion amount can be easily adjusted by directly rotating the core vertical shaft 1. In addition, since the drive pin 6a of the drive plate 6 attached to the core vertical shaft 1 and the engaging portion 8 attached to the core holder 7 are directly engaged, the number of parts is reduced and a simple structure is realized. It became possible.

  By the way, although the core 5 can be moved up and down even if the lateral width of the long hole 8a of the engaging portion 8 engaged with the drive pin 6a is short, the drive pin 6a is formed in the long hole 8a when the core vertical shaft 1 is rotated. Since the core 5 moves up and down while rotating the core inner cylinder 3 in the horizontal direction when coming into contact with the side end, a force for moving the core 5 in the horizontal direction is added to the force for driving the core 5 in the vertical direction during the core vertical operation. Resistance increases.

  In the present invention, the lateral width dimension A of the long hole 8a constituting the engaging portion 8 is set to be longer than the lateral movable range B of the drive pin 6a movable about the core vertical axis 1, and the drive pin 6a Since it was made not to contact the side edge part of the long hole 8a in the movable range, the core 5 could move up and down without rotating. Even in this structure, the drive pin 6a may come into contact with the side end of the long hole 8a. At this time, when the core vertical shaft 1 is rotated while the drive pin 6a is in contact with the side end of the long hole 8a. When the lead 5 is driven while rotating and then the lead vertical shaft 1 is rotated in the reverse direction, the drive pin 6a is separated from the side end of the long hole 8a, and the lead 5 is driven without rotating. For this reason, from the time of the next core up / down operation, the drive pin 6a and the side end of the long hole 8a can be operated without contact, and the core up / down shaft 1 can be rotated with a light operation.

  Also, when the core 5 needs to be replaced in the above configuration, the core vertical shaft 1 is pulled forward and the drive pin 6a and the engaging portion 8 are moved in the same manner as the conventional pinion gear / rack gear core replacement method. A method of releasing the engagement and extracting the core 5 together with the core holder 7 is conceivable. Although this method can also replace the core, this method requires a member for core replacement and increases the number of parts.

  In this invention, the core vertical shaft 1 is disposed at a position laterally deviated from the center of the core inner cylinder 3 when the oil combustor is viewed from the front, and the drive pins 6 a of the drive plate 6 are located on the center side of the core inner cylinder 3. When the lead vertical shaft 1 is rotated between the lead-down position and the lead-up position, the tip position of the drive pin 6a moves in the direction approaching the lead 5 side. The drive pin 6 a can move while maintaining the engagement with the engagement portion 8.

  FIG. 3 shows a state at the time of core replacement. At the center-up position, the upper end of the core holder 7 stops the movement of the core 5 against the lower surface of the core outer cylinder 4, and the core outer cylinder 4 is removed when the core is replaced. The core up-and-down shaft 1 can be rotated in the center-up direction from the maximum combustion position. When the core up-and-down shaft 1 is rotated in the center-up direction from the maximum combustion position, the core up-and-down shaft 1 is Since it is out of the center position, the drive pin 6a movable beyond the top dead center is separated from the core 5, and the tip position of the drive pin 6a is out of the long hole 8a of the engaging portion 8 formed along the circumferential direction. Therefore, the lead 5 can be extracted together with the lead holder 7.

  When the core 5 is attached to the core inner cylinder 3 after the new core 5 is mounted on the core holder 7, the vertical axis of the core is adjusted while aligning the positions of the drive pin 6a of the drive plate 6 and the long hole 8a of the engaging portion 8. The drive pin 8a can be engaged with the long hole 8a by rotating in the core lowering direction so as to return 1 to the maximum combustion position and returning the core vertical shaft 1 to the maximum combustion position. At this time, the core height is determined by the height of the drive pin 6, and if the drive pin 6a and the engaging portion 8 are engaged with each other, it matches the core height before replacement. The core replacement work can be easily done without need.

  Further, in this configuration, the core height is determined by the height of the drive pin 6a of the drive plate 6 movable by the core vertical axis 1, so that the core can be adjusted by changing the dimensions of the drive plate 6 and the rotation range of the core vertical axis 1. It is possible to easily change the moving amount and the center height of the center raising position, and it is possible to easily cope with models having different frame sizes and maximum heat generation amounts.
