Description

この発明は芯上下式の石油燃焼器の芯上下装置に関するものである。   The present invention relates to a core lifting device for a core lifting oil combustor.

油タンクの上方に燃焼筒を配置し、油タンクの燃料を芯を使って燃焼筒の下部へ供給する芯上下式の石油燃焼器が知られており、この石油燃焼器の燃焼量の調節及び消火は操作部によって回動する芯の上下動によって行われている。   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.

この芯上下装置の一般的な構成として、ダイヤル式やレバー式のものがあり、ダイヤル式の芯上下装置には、芯ホルダに取付けたラックギアと芯上下軸の内方端に設けたピニオンギアとの噛合いによって芯を上下動するものがある(特許文献1参照)。一方、レバー式の芯上下装置には、芯に一対の係合ピンを設け、略コ形の駆動レバーの先端部と係合ピンを係止し、芯上下軸に固定した駆動レバーの回動によって芯を上下するものがある(特許文献2参照)。   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).

そして、最近の石油燃焼器は燃焼量を絞っても不完全燃焼を起こしにくい燃焼部の開発が進み、芯高さを調節することで好みの燃焼量で燃焼を行うことができるようになってきた。このため、燃焼中に使用者が望む室温や火力になると、芯上下軸を操作して燃焼量の調節範囲内で火力を調節できるようになっている。   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.

ダイヤル式の芯上下装置はピニオンギアとラックギアのピッチを細かくすることで、芯下げ位置と芯上げ位置との間の芯上下軸の回転量を1回転近くと大きく設定し、芯上下軸の回動に対して芯がゆっくり動くようにして、燃焼量の調節を行いやすくしている。   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.

一方、レバー式の芯上下装置は芯下げ位置から芯上げ位置の間の芯上下軸の回動角度が狭く、芯上下軸を直接操作レバーで回動する構造であると、芯上下軸の回動に対して芯高さが大きく変化するため、最大発熱量を低下させた燃焼状態に合わせて手動による燃焼量調節は難しい。このため、芯上下軸を直接操作レバーで回動させず、操作レバーと芯上下軸との間に部品を追加して、燃焼中の芯位置では操作レバーの駆動に対して芯がゆっくり動くようにして、燃焼量の調節を行いやすくしている(特許文献3参照)。

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).
Japanese Patent Laid-Open No. 11-287406 Japanese Patent No. 29898578 Utility Model No. 2556402

ダイヤル式の芯上下装置は燃焼量の調節は行いやすいが、通常の芯上下操作時には操作つまみを多数操作する必要があるため操作が面倒であった。また、ピニオンギアとラックギアのピッチを細かくすると加工が難しくなり、正確な芯高さを得るためにピニオンギアとラックギアは寸法精度が要求されるので加工時間がかかり、加工費が増加する欠点がある。   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. .

また、芯交換の際にはピニオンギアとラックギアとの噛合いを外して芯を上方に抜き取るため、芯交換後にラックギアとピニオンギアとの噛合い位置を正確に合わせる必要があり、芯交換作業に手間がかかる欠点があった。   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.

一方、レバー式の芯上下装置は、芯下げ位置から芯上げ位置の間の芯上下軸の回転角度が狭いため、操作レバーを使って芯高さを調節することは難しく、燃焼量の調節を行いやすくするためには特許文献3のように燃焼量調節用の部品が不可欠であり、部品点数が増加してしまうものであった。   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.

また、レバー式の芯上下装置は係合ピンと駆動レバーとの係合であるから芯交換作業は比較的簡単に行えるが、芯を上下動するための芯上下軸や駆動レバーは形状が大きく、油タンクに芯を装着するための狭い空間内に多数の部品が存在しており、芯上下構造を複雑にしていた。   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.

このように芯上下式の石油燃焼器でも燃焼量の調節が可能となり、使い勝手は良くなっているが、部品点数の増加や芯上下装置の構造が複雑になるため、製造コストが上昇してしまう。この発明は構造が簡単で燃焼量調節や芯交換作業が簡単に行える芯上下装置を提案するものである。   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.

この発明は上記の課題を解決するもので、油タンク2の底板から立設した芯内筒3と、油タンク2の上面板に取付けた芯外筒4と、芯内筒3に上下動自在に取付けた芯5と、該芯5を上下動する芯上下軸1とを設け、該芯上下軸1の内方端には芯上下軸1を中心に可動する駆動板6を取付け、該駆動板6の可動端から芯5方向に向けて駆動ピン6aを形成し、前記芯5の外周に取付けた芯ホルダ7の側面には前記駆動板6の駆動ピン6a係合する係合部8を設け、芯上下軸1の回動によって可動する駆動板6の駆動ピン6aが芯ホルダ7を駆動して芯5を上下動する石油燃焼器において、前記芯ホルダ7の係合部8は芯5の円周方向に沿った横長の長孔8aで構成し、該長孔8aの横幅寸法Aは芯上下軸1を中心に可動する駆動板6の駆動ピン6aの横方向の可動範囲Bよりも長く設定したことを特徴とするものである。 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.

このため、芯下げ位置から芯上げ位置の間の芯上下軸1の回転範囲は少なくでき、芯上下操作を簡単にできると共に、芯上げ位置では芯上下軸1の回転に対して芯5がゆっくり動くので、燃焼量の調節が行いやすものとなった。また、芯上下軸1の回動時に駆動板6の駆動ピン6aが係合部8の長孔8aの側端部に接触することがなく、芯5が回転することなく芯内筒3に沿って上下動するので芯上下操作をスムーズに行うことができる。 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.

また、前記芯上下軸1は芯内筒3の中心から外れた位置に配置し、芯5の消火位置から最大燃焼位置に至る駆動板6の駆動ピン6aの可動範囲Bでは駆動ピン6aと係合部8との係合を維持し、最大燃焼位置よりも芯上げ方向に回動したときに駆動ピン6aと係合部8との係合が外れ、芯5と一緒に芯ホルダ7抜き取り可能になることにより、芯上下軸1を芯上げ方向に回動するだけで容易に芯5を抜き取ることができると共に、駆動ピン6aと係合部8の高さ関係は一定であるから、芯交換後に芯高さを調節する必要がなく、芯交換作業が容易にできる。
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.

この発明は、芯上下軸1の内方端に取付けた駆動板6の駆動ピン6aと、芯5の外周に取付けた芯ホルダ7の係合部8とを係合し、芯上下軸1を回動時に可動する駆動板6の駆動ピン6aによって芯ホルダ7と一体になった芯5を芯内筒3に沿って上下動するもので、芯下げ位置から芯上げ位置の間の芯上下軸1の回動範囲を狭くでき、芯上下操作が簡単にできるものとなった。   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.

また、駆動板6の駆動ピン6aは芯上下軸1を中心に回転する構成であるから、芯上げ位置に近づくにつれて上下方向の移動量が少なくなり、燃焼中の芯高さでは芯上下軸1の回動に対して芯5がゆっくり動くので、芯上下軸1の回動範囲が狭くても燃焼量の調節が行いやすくなり、操作が簡単で燃焼量の調節が行いやすい芯上下装置を実現できるものとなった。   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.

このように、芯上下軸1の回動範囲が狭くても芯上下軸1を直接回動する構成で燃焼量の調節ができるので、燃焼量の調節のための部品が不要になると共に、油タンク2内に配置される部品も少なくコンパクトにまとめることができ、部品点数が少なくシンプルな構造で実現でき、製造コストを低減することができるものとなった。   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.

また、係合部8を芯5の円周方向に沿った横長の長孔8aで構成し、長孔8aの横幅寸法Aは芯上下軸1を中心に可動する駆動ピン6aの可動範囲Bでは長孔8aの側端部に接触しないように設定したから、芯上下軸1の回動時に芯5が回転することなく芯内筒3に沿って上下方向に移動することができ、芯上下軸1は軽い操作で回動することができる。   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.

また、芯上下軸1を芯内筒3の中心位置から横方向に外れた位置に配置し、最大燃焼位置より芯上げ方向に回動したときに駆動ピン6aと係合部8との係合が外れるようにしたので、芯上下軸1の回動のみで簡単に芯5が抜き取り可能となり、芯5の交換後に芯5を戻したときは、駆動板6の駆動ピン6aと係合部8との係合によって芯高さが決定するから芯高さを調節する必要がなく、芯交換作業が容易にできるものとなった。   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.

図に示す実施例によってこの発明を説明すると、2は石油燃焼器の油タンク、3は油タンク2の底面から立設した芯内筒、4は油タンク2の上面板に着脱可能に取付けた芯外筒、5は芯内筒3に上下動自在に取付けた芯であり、油タンク2の燃料は芯5の下端で吸い上げられ、芯5の上端に供給される。   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.

この発明はダイヤル式の芯上下装置にかかるものであり、1は油タンク2の外側方から挿通させて芯上下操作を行う芯上下軸、9は芯5の上方に配置した燃焼筒、1aは芯上下軸1の外方端に取付けて芯上下軸1を回動する操作つまみであり、操作つまみ1aによって芯上下軸1を芯上げ方向に回動して芯5の上端を燃焼筒9の下部にのぞませ、図示しない点火装置によって着火すると芯5の下端で吸い上げられた燃料が芯5の上端で燃焼し、発生する燃焼炎と燃焼ガスは燃焼筒9で空気の供給を受けて燃焼を完了する。   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.

10は芯上下軸1と連動する回動板、11は芯上下軸1に取付けた戻りばね、12は芯上げ位置の回動板10と係合するストッパーであり、芯上下軸1を芯上げ方向に回動すると、戻りばね11を巻き上げて最大燃焼位置で回動板10とストッパー12とが係合して戻りばね11に蓄力する。   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.

13は前記ストッパー12と連結した感振器であり、感振器13はストッパー12を係合方向に付勢しており、所定振動値で感振器13を構成する感振おもりが転倒するとストッパー12と回動板10の係合を外し、戻りばね11の力で芯上下軸1が芯下げ方向に回転して石油燃焼器を消火することができる。   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.

ところで、最近では燃焼量を絞っても不完全燃焼を起こしにくい燃焼部の開発が進み、燃焼量の調節ができるものが増えており、芯高さを調節することで好みの燃焼量で燃焼を行うことができるようになってきたが、芯上下軸1の回動に対して芯高さが大きく変化すると燃焼量の調節が難しいので、燃焼量の調節を行いやすくするために燃焼中の芯位置では芯上下軸1の回動に対して芯5がゆっくり動くようにする必要がある。   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.

このため、従来のダイヤル式の芯上下装置は、ピニオンギアとラックギアのピッチを細かく設定することで燃焼量の調節を行いやすくしているが、この場合は操作つまみ1aを多数操作しなければならず通常の芯上下操作が煩わしい欠点がある。また、ピニオンギアとラックギアの加工に時間がかかり、加工費も増加してしまうものであった。   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.

一方、レバー式の芯上下装置は操作性は良いものの、芯下げ位置から芯上げ位置の間の芯上下軸1の回動角度が狭いため燃焼量の調節が難しく、燃焼量の調節を行いやすくすると部品点数が増加して構造が複雑になる欠点があり、芯上下式の石油燃焼器で燃焼量の調節ができるものは、製造コストの低減や操作性の向上などの課題があり、まだまだ改善の余地が残るものであった。   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.

この発明は上記の課題を解決して簡単な構造で操作のしやすい芯上下装置を提案するもので、6は芯上下軸1の内方端に設けた芯上下軸1を中心に可動する駆動板、6aは駆動板6の可動端に設けた駆動ピンであり、該駆動ピン6aは駆動板6から芯5側に向けて伸ばしている。   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.

7は芯5の外周に取付けた芯ホルダ、8は芯ホルダ7に取付けた係合部であり、駆動板6の駆動ピン6aと係合する。図に示す実施例の係合部8は芯5の円周方向に沿った横長の長孔8aで構成しており、芯上下軸1を回動して駆動板6が可動すると駆動ピン6aが芯上下軸1を中心に回動し、駆動板6の駆動ピン6aが係合する係合部8に力を加え、芯ホルダ7と一体になった芯5が芯内筒3に沿って上下動する。   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.

芯5の高さは芯上下軸1を中心に回転する駆動板6の駆動ピン6aの高さと一致するものであり、芯上下軸1を芯下げ位置に回動したときは駆動板6の駆動ピン6aが下死点付近に位置し、このとき芯高さは最も低くなる。そして、芯上下軸1を芯上げ位置まで回動したときは、駆動ピン6aが上死点付近に位置しており、芯高さは最も高くなる。このため、芯下げ位置から芯上げ位置の間の芯上下軸1の回転量を半回転以下に設定することができ、操作つまみ1aを多数操作する必要がなくなり、ダイヤル式の芯上下装置でも芯上下操作の煩わしさのない芯上下装置が構成できた。   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.

また、駆動板6の駆動ピン6aは芯上下軸1を中心に回転する構成であるので、上死点付近に近づくにつれて上下方向の移動量が少なくなるから、芯上げ位置では芯上下軸1の回動に対して芯5の移動が少なくなる。このため、最大燃焼位置から燃焼量を低下させる芯5の調節範囲内では芯上下軸1の回動に対して芯5がゆっくり動くようになり、燃焼量の調節を容易に行うことができるものである。   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.

このように、芯上下軸1の回動範囲が狭くても燃焼中の芯位置では芯5がゆっくり動くので、芯上下軸1を直接回動する構成で燃焼量の調節が容易にできるものであり、また、芯上下軸1に取付けた駆動板6の駆動ピン6aと芯ホルダ7に取付けた係合部8とが直接係合する構成であるから、部品点数が少なくなり簡単な構造で実現できるものとなった。   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.

ところで、駆動ピン6aと係合する係合部8の長孔8aの横幅は短くても芯5の上下動ができるが、芯上下軸1を回動するときに駆動ピン6aが長孔8aの側端部に接触すると芯5が芯内筒3を横方向に回転しながら上下動するため、芯上下操作時には芯5を上下方向に駆動する力に芯5を横方向に動かす力が加わり、抵抗が大きくなる。   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.

この発明では、係合部8を構成する長孔8aの横幅寸法Aを芯上下軸1を中心に可動する駆動ピン6aの横方向の可動範囲Bよりも長く設定しており、駆動ピン6aの可動範囲では長孔8aの側端部に接触しないようにしたので、芯5が回転することなく上下動できるものとなった。この構造でも駆動ピン6aが長孔8aの側端部に接触することがあるが、このときは駆動ピン6aが長孔8aの側端部に接触した状態のまま芯上下軸1を回動すると芯5が回転しながら駆動し、その後芯上下軸1を逆に回動したときは駆動ピン6aが長孔8aの側端部から離れ、芯5は回転することなく駆動する。このため、次回の芯上下操作時からは駆動ピン6aと長孔8aの側端部が接触することなく操作でき、芯上下軸1の回動は軽い操作でできるものとなった。   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.

また、上記構成において芯5の交換作業が必要になったときは、従来のピニオンギアとラックギアの芯交換方法と同様に芯上下軸1を手前に引いて駆動ピン6aと係合部8との係合を外し、芯ホルダ7ごと芯5を上方に抜き取る方法が考えられる。この方法でも芯交換は可能であるが、この方法では芯交換のための部材が必要となり部品点数が増えてしまう。   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.

この発明では芯上下軸1を石油燃焼器を正面から見たときに芯内筒3の中心から横方向に外れた位置に配置し、駆動板6の駆動ピン6aが芯内筒3の中心側に可動するように設定しており、芯上下軸1を芯下げ位置から芯上げ位置までの間で回動するときは、駆動ピン6aの先端位置が芯5側に近づく方向に可動するので、駆動ピン6aが係合部8との係合を維持したまま可動することができる。   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.

図3は芯交換時の状態を示すものであり、芯上げ位置では芯ホルダ7の上端が芯外筒4の下面にあたって芯5の移動を止めており、芯交換時に芯外筒4を取外すと芯上下軸1が最大燃焼位置より芯上げ方向に回動できるようになっており、芯上下軸1を最大燃焼位置よりも芯上げ方向に回動すると、芯上下軸1は芯内筒3の中心位置から外れているので、上死点を越えて可動する駆動ピン6aは芯5から離れ、駆動ピン6aの先端位置は円周方向に沿って形成した係合部8の長孔8aから外れるので、芯ホルダ7ごと芯5を抜き取ることができるようになる。   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.

そして、新しい芯5を芯ホルダ7に装着後、芯5を芯内筒3に取付けるときは、駆動板6の駆動ピン6aと係合部8の長孔8aとの位置を合わせながら芯上下軸1を最大燃焼位置に戻すように芯下げ方向に回動し、芯上下軸1を最大燃焼位置まで戻せば駆動ピン8aが長孔8aに係合することができる。このとき芯高さは駆動ピン6の高さによって決定するものであり、駆動ピン6aと係合部8とが係合すれば交換前の芯高さと一致するので、芯高さの調節は特に必要なく芯交換作業が容易にできるものとなった。   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.

また、この構成では芯上下軸1によって可動する駆動板6の駆動ピン6aの高さによって芯高さが決定するので、駆動板6の寸法や芯上下軸1の回動範囲の変更によって芯の移動量や芯上げ位置の芯高さを簡単に変更することができ、枠体の大きさや最大発熱量の異なる機種への対応が容易にできるものとなる。   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.
