- An object of the present invention is to provide a lead for a liquid fuel combustion appliance that can reduce the amount of combustion even if tar adheres and can accommodate the combustion portion in the lead accommodating cylinder. There is.
- Another object of the present invention is to provide a core for a liquid fuel combustion instrument that can achieve the above-mentioned object with a structure that is easy to manufacture.
- Another object of the present invention is to provide a core for a liquid fuel combustor capable of setting a combustion amount by the structure itself.
- the liquid fuel combustion instrument core of the present invention includes a fuel suction core having a function of sucking up liquid fuel upward, and a heat-resistant core.
- 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.
- 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.
- 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.
- vertical direction means a vertical direction when the core is used in an oil burning appliance
- lateral direction means a direction intersecting or orthogonal to the “vertical direction”.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- n is a positive integer of 1 or more
- 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.
- 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. .
- 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.
