[0004] 従来の芯では、燃焼部において燃料を気化させる気化部分は、縦糸条の切断端 部が解されて構成されている。そして縦糸条の切断端部の間に位置する内側の縦糸 条の折り返し部が、解された縦糸条の切断端部間に所定のスペースを形成している 。解された切断端部には、燃料に含まれるタールが付着して、その部分の体積が増 加する。上記芯を芯収容筒内に収容する際に、付着したタールは障害となる。しかし 従来の構造では、タールの付着により増加した体積分は、前述のスペース内に逃げ る。その結果、タールの付着量が増力!]しても、芯の燃焼部が芯収容筒内に入らなくな つて、消火動作を行えなくなる事態が発生することを阻止できる。 [0004] In the conventional core, the vaporizing portion for vaporizing the fuel in the combustion portion is configured by breaking the cut end portion of the warp yarn. Then, the folded portion of the inner warp yarn located between the cut ends of the warp yarn forms a predetermined space between the cut end portions of the warped yarn. Tar that is contained in the fuel adheres to the cut end of the crack, and the volume of that portion increases. When the core is housed in the core housing cylinder, the attached tar becomes an obstacle. However, in the conventional structure, the volume increased due to the adhesion of tar escapes into the above-mentioned space. As a result, it is possible to prevent the occurrence of a situation in which the fire extinguishing operation cannot be performed if the burning portion of the wick does not enter the wick accommodating cylinder even if the tar adhesion amount is increased!].

[0005] し力しながら従来の構造では、前述のスペースを形成するために、燃焼部における 燃料を気化させる部分 (切断端部が解されて形成される部分)の体積が少なくなつて[0005] However, in the conventional structure, the volume of the portion that vaporizes the fuel in the combustion portion (portion formed by breaking the cut end portion) is reduced in order to form the above-described space.
、燃焼量を増大させることができない。そのため、燃焼部にタールが付着し始めると、 燃焼量が大幅に低下する問題が生じる。 The amount of combustion cannot be increased. For this reason, when tar begins to adhere to the combustion section, there is a problem that the amount of combustion is greatly reduced.

Heat-resistant core for fuel suction The fuel sucked up by the fuel suction core disposed on the upper side of the wick absorbs the fuel further upward, raises the suction !, and raises the suction and raises the fuel continuously. And a combustion section for vaporizing and burning the liquid fuel. The core of the present invention is disposed in a core housing cylinder having an upper opening provided in an oil combustion appliance, and is used by causing the combustion section to protrude above the upper opening force of the core housing cylinder during combustion. Further, the heat-resistant core is configured in a state in which the warp component and the weft component are knitted. The warp constituting portion is constituted by arranging a plurality of warp yarns, and the combustion portion is constituted by an end portion formed by cutting a plurality of warp yarns. The weft constituting portion is knitted with a plurality of yarn bundles constituting the warp constituting portion, and is composed of a plurality of weft yarns that are arranged at intervals in the vertical direction and extend in the transverse direction. In the present specification, “vertical direction” means a vertical direction when the core is used in an oil burning appliance, and “lateral direction” means a direction intersecting or orthogonal to the “vertical direction”.
このような基本構成において、本発明では、複数本の横糸条のうち最も上方に位置 する 1本の横糸条が、耐熱性芯部の燃焼部の中間領域を横方向に延びるように配置 する。従来は、気化量を増大させること及び長期間にわたって気化量が減少しないよ うにするためには、燃焼部を構成する複数本の縦糸が横方向に広がること (拘束され ないこと)が好ましいと考えるのが当業者の常識であった。し力しながら燃焼部を構成 する複数本の縦糸の本数が多くなり、燃焼部に供給される燃料が多くなれば、このよ うな常識にこだわる必要性はないと発明者は考えた。そして従来の常識から判断す れば、好ましくないと考えられる燃焼部における縦糸の横方向への広がりを規制する ことを研究した。研究の結果、最も上方に位置する 1本の横糸条を、耐熱性芯部の燃 焼部の中間領域を横方向に延ばすように配置して、燃焼部における縦糸の横方向 への広がりを規制することが、気化量を大幅に減少させることなくタールの付着量を 減少させて、し力も気化量の低下を長期間にわたって阻止することができることを発 明者は見い出した。最も上方に位置する 1本の横糸条の位置は、吸い上げ部を通し て供給される燃料の量に応じて適宜に定めることになる。具体的には、 1本の横糸条 の位置は、タールの蓄積により燃焼部の先端部からの燃料の気化が大きく阻害され ず且つ 1本の横糸条の位置にタールが付着したとしても燃焼部が芯収容筒内を上下 方向に変位し得る程度のタールし力付着しな 、位置である。 In such a basic configuration, in the present invention, one of the plurality of weft yarns located at the uppermost position is arranged so as to extend in the lateral direction in the intermediate region of the combustion portion of the heat resistant core. Conventionally, in order to increase the amount of vaporization and not to reduce the amount of vaporization over a long period of time, it is preferable that the warp yarns constituting the combustion section spread in the lateral direction (not constrained). This is the common sense of those skilled in the art. The inventor considered that there is no need to stick to such common sense if the number of warp yarns constituting the combustion section increases while the force is increased and the amount of fuel supplied to the combustion section increases. And judging from conventional common sense, we studied to regulate the spread of warp yarns in the transverse direction in the combustion section, which is considered undesirable. As a result of research, the uppermost single weft yarn is placed so that the middle region of the heat-resistant core's burning part extends in the transverse direction, and the spread of warp yarns in the transverse direction in the burning part is regulated. The inventors have found that reducing the amount of tar deposited without significantly reducing the amount of vaporization and preventing the decrease in the amount of vaporization over a long period of time. The position of the uppermost single weft will be determined appropriately according to the amount of fuel supplied through the suction part. Specifically, the position of one weft does not significantly inhibit vaporization of fuel from the tip of the combustion section due to the accumulation of tar, and even if tar adheres to the position of one weft, Up and down in the lead tube It is a position where there is no tarning force that can be displaced in the direction.
[0011] 本発明の構成よれば、タールは燃焼部の中間領域に位置する横糸条付近に付着 する。そしてタールの付着量は、最も上方の 1本の横糸条を中間領域よりも上方また は下方に配置する場合よりも、タールの付着量が減る。またタールが付着しても横糸 条の存在により、燃焼部を構成する複数の縦糸の横方向への広がりが規制されてい るので、燃焼部が芯収容筒内に収容できなくなる事態が発生するのを有効に抑制で きる。  [0011] According to the configuration of the present invention, tar adheres to the vicinity of the weft yarn located in the intermediate region of the combustion section. The tar adhesion amount is smaller than that in the case where the uppermost single weft is arranged above or below the middle region. In addition, even if tar adheres, the presence of the weft yarn restricts the spread of the plurality of warp yarns constituting the combustion portion in the lateral direction, which may cause a situation where the combustion portion cannot be accommodated in the core housing cylinder. Can be effectively suppressed.
[0012] なお 1本の横糸条の位置は、燃料の質が悪い場合 (燃料に含まれるタール成分が 多い場合)において、燃焼部の先端部から 5± 1. 5mmの範囲内の位置にすることが 好ましい。この範囲を超えると、気化量が減少し且つタールが芯の先端に付着して着 火し難くなる。またこの範囲より下では、気化量が増大するものの横方向へ広がった 燃焼部に付着したタールの存在が燃焼部を芯収容筒内に収容する際の障害となる 可能性が高くなる。  [0012] It should be noted that the position of one weft should be within a range of 5 ± 1.5 mm from the tip of the combustion section when the fuel quality is poor (when the tar component in the fuel is high). It is preferable. Beyond this range, the amount of vaporization decreases and tar adheres to the tip of the core, making it difficult to ignite. Below this range, although the amount of vaporization increases, the presence of tar adhering to the combustion part spreading in the lateral direction increases the possibility of becoming an obstacle when the combustion part is housed in the core housing cylinder.
[0013] 縦糸構成部としては、複数本の縦糸条が並べられて構成された 1組以上の糸条束 力 上方位置と下方位置とに折り返し部が繰り返し形成されるように多数回折り返さ れた後、上方位置にある折り返し部が所定の切断位置で切断されて燃焼部を形成す るように構成されたものが好ましい。このような構造の縦糸構成部は、周知のラッセル 編み機を用いて簡単に作ることができる。またこの構造であれば、燃料吸い上げ用芯 部から吸い上げた燃料をスムーズに燃焼部へと導くことができる。なおこの場合、燃 料吸い上げ用芯部も、ラッセル編み機で編むことができる構造にすれば、既存の設 備を用いて簡単に芯を製造することができる。  [0013] As the warp component, one or more sets of yarn bundles composed of a plurality of warps arranged side by side are repeatedly folded so that the folded portion is repeatedly formed at the upper position and the lower position. Thereafter, it is preferable that the folded portion at the upper position is cut at a predetermined cutting position to form a combustion portion. The warp component having such a structure can be easily made using a known Russell knitting machine. Further, with this structure, the fuel sucked up from the fuel sucking core can be smoothly guided to the combustion part. In this case, if the core portion for sucking up the fuel is also structured so as to be knitted by a Russell knitting machine, the core can be easily manufactured using existing equipment.
[0014] なお前述の上方位置にある折り返し部において最も内側に位置する 1本の縦糸条 またはこの 1本の縦糸条を含んでこの 1本の縦糸条と隣接する複数本の縦糸条を、切 断位置よりも下方の位置で折り返しておくのが好ま U、。このように上方位置にある折 り返し部を構成する縦糸条を切断位置よりも下方の位置に残すと、残された縦糸条の 折り返し部の上方にスペースが形成されることになる。このスペースの数及び幅寸法 を適宜に定めると、吸い上げ部力 燃焼部に供給される燃料の量を調節することが 可能になる。したがって燃料吸い上げ用芯部の構造を可能な限り燃料を吸い上げる ことができる構造にしたとても、耐熱性芯部において、前述のスペースの数及び幅寸 法を適宜に定めることにより、燃焼部における気化量を芯の構造によって調節するこ とが可能になる。 [0014] It should be noted that one warp located at the innermost side in the folded portion at the above-mentioned upper position or a plurality of warp yarns including this one warp and adjacent to this one warp is cut. It is preferable to fold back at a position below the cut position. In this way, if the warp yarn constituting the folded portion at the upper position is left at a position below the cutting position, a space is formed above the folded portion of the remaining warp yarn. If the number and width dimensions of these spaces are appropriately determined, it becomes possible to adjust the amount of fuel supplied to the suction portion combustion section. Therefore, suck up the fuel as much as possible in the structure of the fuel suction core. In a heat-resistant core having a structure that can be formed, the amount of vaporization in the combustion section can be adjusted by the structure of the core by appropriately determining the number of spaces and the width dimension described above.
[0015] なお上方位置にある複数の折り返し部のうち n(nは 1以上の正の整数)個おきに現 れる折り返し部において最も内側に位置する 1本の縦糸条を、切断位置よりも下方の 位置で折り返し、 1本の縦糸条に含まれる 1本以上の縦糸をこの 1本以上の縦糸を除 く残りの複数本の縦糸の折り返し位置よりも切断位置寄りの位置で折り返すようにして もよい。この場合には、 nの値を任意に定めることにより、前述のスペースの数を決定 することができる。この nは、燃料吸い上げ用芯部が吸い上げた燃料を耐熱性芯部の 吸い上げ部力 燃焼部に供給する際に、燃焼部において燃焼に最適な量に近い量 まで限定するように定めるのが好ましい。  [0015] Of the plurality of folded portions at the upper position, one warp located on the innermost side in the folded portion that appears every n (n is a positive integer of 1 or more) is positioned below the cutting position. The one or more warp yarns contained in one warp thread may be folded back at a position closer to the cutting position than the return position of the remaining plurality of warp threads excluding the one or more warp threads. Good. In this case, the number of spaces can be determined by arbitrarily determining the value of n. This n is preferably determined so that when the fuel sucked up by the fuel sucking wick is supplied to the wicking force of the heat-resistant wick, it is limited to an amount close to the optimum amount for combustion in the burning part. .
[0016] なお上方位置にある折り返し部において最も内側に位置する 1本の縦糸条を、切 断位置よりも下方の位置で折り返し、またこの 1本の縦糸条に含まれる 1本以上の縦 糸を該 1本以上の縦糸を除く残りの複数本の縦糸の折り返し位置よりも切断位置寄り の位置で折り返す。そしてこの 1本の縦糸と、最も上方に位置する 1本の横糸条とを 編むようにする。このようにすると 1本の縦糸が最も上方に位置する 1本の横糸条を係 止する機能を発揮し、この 1本の横糸条が切断部分力 抜け出るのを防止することが できる。  [0016] Note that one warp located at the innermost side in the folded portion at the upper position is folded back at a position below the cutting position, and one or more warps included in the one warp. Is folded at a position closer to the cutting position than the folding position of the remaining plurality of warp threads excluding the one or more warp threads. Then, the single warp and the uppermost one weft are knitted. In this way, one warp thread functions to lock one weft thread that is positioned at the uppermost position, and it is possible to prevent this one weft thread from coming off the cutting partial force.
[0017] 縦糸構成部を構成するために用いる糸条束の数は、任意である。例えば、 2組の糸 条束を横に並べた状態で一緒に、上方位置と下方位置とに折り返し部が繰り返し形 成されるように多数回折り返した後、上方位置にある折り返し部を所定の切断位置で 切断して燃焼部を形成するようにしてもよ!、。このようにすると芯部の製造が容易にな る。  [0017] The number of yarn bundles used for constituting the warp constituting portion is arbitrary. For example, in a state where two sets of yarn bundles are arranged side by side, after folding back so that the folded portion is repeatedly formed at the upper position and the lower position, the folded portion at the upper position is set to a predetermined position. It may be cut at the cutting position to form a combustion part! This facilitates the manufacture of the core part.

The core inner cylinder 21 constituting the remaining part of 17 is fixed. Inside the core outer cylinder 19 is housed a drive mechanism 23 for engaging the drive pin 9 and moving the core 1 in the vertical direction. The driving force of the driving mechanism 23 is generated by rotating a rotary core up / down handle 25. Note that the configuration of the drive mechanism 23 is well known, and thus the description thereof is omitted. An outer flame cylinder support portion 20 that is bent outwardly and supports the lower end portion of the outer flame cylinder 27 of the combustion cylinder is formed on the upper end portion of the core outer cylinder 19.

During fire extinguishing, the core upper and lower handles 25 are rotated in the opposite direction to lower the core 1 downward, and the combustion part 5B is accommodated in the core accommodating cylinder 17. Although not shown in the figure, this oil-fired appliance automatically extinguishes fire when an earthquake occurs or when the oil-burning appliance collapses and the core 1 is instantaneously pulled into the core housing cylinder 17. It is equipped with an automatic fire extinguishing mechanism. Since the structure of this automatic fire extinguishing mechanism is well known, the description is omitted.
[0022] 次に本実施の形態の石油燃焼器具用芯 1の構造について説明する。図 4は、芯 1 の構造と芯の製造過程を説明するために、製造過程の途中における芯 1の耐熱性芯 部 5の一部と燃料吸い上げ用芯部 3の一部とを拡大して示した図である。耐熱性芯 部 5は、燃料吸 、上げ用芯部 3の上側に配置されて燃料吸 、上げ用芯部 3が吸 、上 げた燃料を更に上方に吸 、上げる吸 、上げ部 5Aと、吸 、上げ部 5Aと連続して形成 されて吸い上げ部 5Aを通して供給された液体燃料を気化して燃焼させる燃焼部 5B とを備えている。 [0022] Next, the structure of the oil burning appliance core 1 of the present embodiment will be described. Fig. 4 is an enlarged view of part of the heat-resistant core part 5 of the core 1 and part of the fuel suction core part 3 in the middle of the manufacturing process in order to explain the structure of the core 1 and the manufacturing process of the core. FIG. The heat-resistant core 5 is disposed on the upper side of the fuel suction / raising core 3 to absorb the fuel, the suction core 3 absorbs, and further absorbs and raises the raised fuel. And a combustion section 5B that is formed continuously with the raising section 5A and vaporizes and burns the liquid fuel supplied through the suction section 5A.
[0023] 燃料吸い上げ用芯部 3は、綿糸力もなる縦糸構成部 31と横糸構成部 33とがラッセ ル編み機で編成された状態で構成されている。図 1に示すように、横糸構成部 33は 、耐熱性芯部 5に近い上方領域と下側端部近傍の領域において縦糸構成部 31と編 成されており、中間領域においては、縦糸構成部 31のみが存在している。縦糸構成 部 31は、複数本の縦糸条 32が複数本並べられて構成された 2組以上の糸条束 35A 及び 35Bが、上方位置と下方位置とに折り返し部 37及び 39 (図 1)が繰り返し形成さ れるように多数回折り返されて構成されている。また横糸構成部 33は、縦糸構成部 3 1を構成する 2組の糸条束 35A及び 35Bと編成されている。横糸構成部 33を構成す る複数本の横糸 34は、それぞれ上下方向に間隔をあけて配置され且つ横方向に延 びている。この例では、横糸 34は、いわゆる鎖編みによって縦糸構成部 31を構成す る 2組の糸条束 35A及び 35Bと編成されている。  [0023] The fuel suction core 3 is configured in a state in which the warp component 31 and the weft component 33, which also have a cotton yarn force, are knitted by a rassel knitting machine. As shown in FIG. 1, the weft component 33 is knitted with the warp component 31 in the upper region near the heat-resistant core 5 and the region near the lower end, and in the middle region, the warp component Only 31 are present. The warp constituting portion 31 includes two or more sets of yarn bundles 35A and 35B configured by arranging a plurality of warp yarns 32, and folded portions 37 and 39 (FIG. 1) at an upper position and a lower position. It is configured to be folded many times so that it is repeatedly formed. The weft constituting portion 33 is knitted with two sets of yarn bundles 35A and 35B constituting the warp constituting portion 31. The plurality of wefts 34 constituting the weft constituting part 33 are arranged at intervals in the vertical direction and extend in the lateral direction. In this example, the weft 34 is knitted with two sets of yarn bundles 35A and 35B constituting the warp constituting portion 31 by so-called chain knitting.

The fuel suction / raising core 3 and the heat-resistant core 5 are both connected by a connecting weft 40. When making the warp component 41, first, two sets of yarns composed of a plurality of warp yarns 42 are arranged. The bundles 45A and 45B are folded back in a meandering manner so that the folded portions 47 and 49 are repeatedly formed at the upper position and the lower position. At the same time, the weft component 43 is also formed. Thereafter, the folded portion 47 located at the upper position is cut along a predetermined cutting position CL to form the burning portion 5B. In the present embodiment, the folded portion 47 located at the upper position is folded at a position below the one warp thread 42A force cutting position CL located on the innermost side. In this embodiment of the warp yarn 42A, the warp yarn 42A is knitted with the weft yarn 44B, which will be described later. The one or more warp threads 42a included are folded back at a position closer to the cutting position CL than the folding position of the remaining plurality of warp threads 42b excluding the one or more warp threads 42a.

In the present embodiment, the force that turns back one warp thread 42A at a position lower than the cutting position CL. The plurality of warp threads 42 may be turned back at a position below the cutting position. Good. In such a case, one of the plurality of warp yarns 42 is entangled with one weft yarn 44A located at the uppermost position, and the remaining warp yarn 42 is entangled with the second weft yarn 44B. Even so,

The five weft yarns 44 A to 44 E are arranged at intervals in the vertical direction, and extend in the lateral direction intersecting or orthogonal to the direction in which the warp yarns 42 extend. In order to form the combustion portion 5B, the folded portion 47 at the upper position is cut at the cutting position CL shown in FIG. Figure 5 shows the enlarged state after cutting. The ends of the cut warp yarns 42 are naturally unwound, and the ends of the warp yarns 42 located above the weft yarns 44A in the combustion section 5B are in the state of fine glass fiber brushes. ing. The shape of the folded portion 49 in the lower position of the warp component 41 of the heat-resistant core 5 and the folded portion 37 in the upper position of the fuel suction core 3 are determined so as to increase the contact area between them. . Specifically, the yarn bundle 45B and the yarn bundle 35A are in contact with each other over a longer distance than the force. That is, the yarn bundle 45B is folded back. In the section, the folded shape of the yarn bundle 45B is determined so that one warp yarn in the yarn bundle 45B contacting the yarn bundle 45A contacts itself. Similarly, in the folded portion of the yarn bundle 35A in the fuel suction core 3, the yarn bundle 35A of the yarn bundle 35A is brought into contact so that one warp of the yarn bundle 35A that contacts the yarn bundle 35B contacts itself. The folded shape is defined. The two weft yarns 40 are knitted by the folded portion of the yarn bundle 45B and the folded portion of the yarn bundle 35A and the chain knitting.
[0027] 上記のような基本構成において、本発明では、 5本の横糸条 44A— 44Eのうち最も 上方に位置する 1本の横糸条 44Aを、耐熱性芯部 5の燃焼部 5Bの中間領域を横方 向に延びるように配置して 、る。このようにすると燃焼部 5Bにおける縦糸の横方向へ の広がりを多少は規制されることになる。しかしながら、このような構成を採用すると、 気化量を大幅に減少させることなくタールの付着量を減少させて、し力も気化量の低 下を長期間にわたって阻止することができることを発明者は見い出した。最も上方に 位置する 1本の横糸条 44Aの位置は、吸い上げ部を通して供給される燃料の量に応 じて適宜に定めることになる。具体的には、 1本の横糸条 44Aの位置は、タールの蓄 積により燃焼部 5Bの先端部からの燃料の気化が大きく阻害されず且つ 1本の横糸条 44Aの位置にタールが付着したとしても燃焼部 5Bが芯収容筒 17内を上下方向に変 位し得る程度のタールし力 f寸着しな 、位置である。より具体的な 1本の横糸条 44Aの 位置は、燃料の質が悪い場合 (燃料に含まれるタール成分が多い場合)において、 燃焼部の先端部から 5 ± 1. 5mmの範囲内の位置にすることが好ましい。この範囲を 超えると、気化量が減少し且つタールの付着量が増大する。またこの範囲より下では 、気化量が増大するものの横方向へ広がった燃焼部 5Bに付着したタールの存在が 燃焼部 5Bを芯収容筒 17内に収容する際の障害となる可能性が高くなる。  [0027] In the basic configuration as described above, in the present invention, among the five weft yarns 44A-44E, the uppermost one weft yarn 44A is used as an intermediate region of the combustion portion 5B of the heat-resistant core 5. Are arranged so as to extend in the lateral direction. In this way, the spread of the warp yarn in the transverse direction in the combustion section 5B is somewhat restricted. However, the inventor has found that when such a configuration is adopted, the amount of tar adhered can be reduced without significantly reducing the amount of vaporization, and the reduction in the amount of vaporization can be prevented over a long period of time. . The position of the single weft 44A located at the uppermost position is appropriately determined according to the amount of fuel supplied through the suction part. Specifically, in the position of one weft 44A, the accumulation of tar does not significantly inhibit the vaporization of fuel from the tip of the combustion section 5B, and the tar adheres to the position of one weft 44A. Even so, it is the position where the combustion force 5B does not adhere to the tarning force f that can displace the inside of the core housing cylinder 17 in the vertical direction. The more specific position of one weft 44A should be within a range of 5 ± 1.5 mm from the tip of the combustion section when the fuel quality is poor (when the tar component in the fuel is high). It is preferable to do. Beyond this range, the amount of vaporization decreases and the amount of tar attached increases. Below this range, although the amount of vaporization increases, the presence of tar adhering to the combustion section 5B that spreads in the lateral direction increases the possibility of becoming an obstacle when the combustion section 5B is housed in the core housing cylinder 17. .
[0028] 本実施の形態の構造にすると、燃料に含まれるタールは燃焼部 5Bの中間領域に 位置する横糸条 44A付近に付着する。このようにした場合には、横糸条 44Aを中間 領域よりも上方または下方に配置する場合よりも、タールの付着量が減ることが試験 により確認された。またタールが付着しても横糸条 44Aの存在により、燃焼部 5Bを構 成する複数の縦糸 42の横方向への広がりが規制されているので、燃焼部 5Bが芯収 容筒 17内に収容できなくなる事態が発生するのを有効に抑制できる。また本実施の 形態のように、上方位置にある折り返し部 47の一部 (42A)を構成する縦糸条 45Bを 切断位置 CLよりも下方の位置に残すと、残された縦糸条 (42A)の折り返し部の上方 にスペース Sが形成される。このスペース Sの数及び幅寸法を適宜に定めると、吸い 上げ部 5Aから燃焼部 5Bに供給される燃料の量を調節することが可能になる。したが つて燃料吸い上げ用芯部 3の構造を可能な限り燃料を吸い上げることができる構造 にしたとても、耐熱性芯部 5において、前述のスペース Sの数及び幅寸法を適宜に定 めることにより、燃焼部 5Bにおける気化量を芯の構造によって調節することが可能に なる。 [0028] According to the structure of the present embodiment, the tar contained in the fuel adheres to the vicinity of the weft yarn 44A located in the intermediate region of the combustion section 5B. In such a case, it was confirmed by a test that the amount of tar attached was reduced as compared with the case where the weft yarn 44A was arranged above or below the intermediate region. Even if tar adheres, the presence of the weft 44A restricts the spread of the plurality of warps 42 constituting the combusting section 5B in the lateral direction, so that the combusting section 5B is accommodated in the core accommodating cylinder 17. It is possible to effectively suppress the situation where it becomes impossible. Also this implementation As shown in the figure, if the warp yarn 45B constituting a part (42A) of the folded portion 47 at the upper position is left at a position below the cutting position CL, the upper portion of the folded portion of the remaining warp yarn (42A) A space S is formed. If the number and width dimensions of the spaces S are appropriately determined, it is possible to adjust the amount of fuel supplied from the suction part 5A to the combustion part 5B. Therefore, the structure of the fuel sucking core 3 is made so that fuel can be sucked up as much as possible. In the heat-resistant core 5, the number and width dimensions of the space S are appropriately determined. Thus, the amount of vaporization in the combustion section 5B can be adjusted by the structure of the core.
[0029] なお本実施の形態では、上方位置にある複数の折り返し部 47のすべてにおいて、 切断位置 CLで切断されな 、縦糸条 42Aを残すようにして 、るが、 n (nは 1以上の正 の整数)個おきに現れる折り返し部 47において最も内側に位置する 1本の縦糸条を 、切断位置よりも下方の位置で折り返し、 1本の縦糸条に含まれる 1本以上の縦糸を この 1本以上の縦糸を除く残りの複数本の縦糸の折り返し位置よりも切断位置 CL寄り の位置で折り返すようにしてもよい。この場合には、 nの値を任意に定めることにより、 前述のスペース Sの数を決定することができる。この nは、燃料吸い上げ用芯部 3が吸 い上げた燃料を耐熱性芯部 5の吸い上げ部 5Aから燃焼部 5Bに供給する際に、燃 焼部 5Bにお 、て燃焼に最適な量に近 、量まで限定するように定めるのが好ま 、。  In the present embodiment, in all of the plurality of folded portions 47 at the upper position, the warp yarn 42A is left uncut at the cutting position CL, but n (n is 1 or more) One warp located at the innermost side in the folded portion 47 appearing every other positive integer) is folded back at a position below the cutting position, and one or more warps contained in one warp are You may make it return in the position near cutting position CL rather than the return position of the remaining multiple warp yarn except the warp yarn more than. In this case, the number of spaces S can be determined by arbitrarily determining the value of n. This n is the amount optimal for combustion in the combustion section 5B when the fuel sucked up by the fuel suction core section 3 is supplied from the suction section 5A of the heat-resistant core section 5 to the combustion section 5B. Recently, it is preferable to limit to the amount.
[0030] 上記実施の形態では、縦糸構成部 41を構成するために 2組の糸条束を用いたが、 理論的には、縦糸構成部 41を構成するために用いる糸条束の組数 (m)は任意であ る。  [0030] In the above embodiment, two sets of yarn bundles are used to form the warp constituting portion 41. Theoretically, the number of sets of yarn bundles used to constitute the warp constituting portion 41 is used. (m) is optional.
[0031] 上記実施の形態では、縦糸 42bの折り返し部までが、芯収容筒 17の上側開口部 1 6から上方に突出する燃焼部 5Bを構成している。し力しながら縦糸 42bの折り返し部 力 芯収容部筒 17の上側開口部 16から上方に必ず突出していることは必ずしも必 要ない。場合によっては、燃焼時において、縦糸 42bの折り返し部が芯収容筒 17内 に位置していてもよいのは勿論である。また本実施の形態では、上から 2番目の横糸 条 44Bは、芯収容筒 17の上側開口部 16とほぼ一致する位置にある力 2番目の横 糸条 44Bが上側開口部 16よりも上方に多少露出していても実質的な問題はない。 産業上の利用可能性 本発明によれば、芯の燃焼部へのタールの付着量を減らして、しかも燃焼部が芯 収容筒内に収容できなくなる事態が発生するのを有効に抑制できるので、質の悪い 油を使用した場合でも、長期にわたって芯を使用することが可能になる利点が得られ る。 [0031] In the above embodiment, the portion up to the folded portion of the warp yarn 42b constitutes the combustion portion 5B protruding upward from the upper opening 16 of the core housing cylinder 17. It is not always necessary that the folded portion of the warp yarn 42b protrudes upward from the upper opening portion 16 of the core accommodating portion cylinder 17 while being pressed. In some cases, of course, the folded portion of the warp yarn 42b may be positioned in the core housing cylinder 17 during combustion. Further, in the present embodiment, the second weft yarn 44B from the top has a force that is in a position substantially coinciding with the upper opening 16 of the core accommodating cylinder 17, and the second weft yarn 44B is located above the upper opening 16. Even if it is slightly exposed, there is no substantial problem. Industrial applicability According to the present invention, it is possible to reduce the amount of tar adhering to the combustion portion of the wick, and to effectively suppress the occurrence of a situation in which the combustion portion cannot be accommodated in the wick housing cylinder. Even in this case, there is an advantage that the core can be used for a long time.
