Description

[Detailed description of the invention] Industrial field of application This invention relates to a wick for combustion appliances used in oil burning appliances such as oil stoves and oil stoves.

BACKGROUND OF THE INVENTION Conventionally, knitted cores called latssel knitting, which are knitted with a warp knitting machine, have been known as cores for oil-burning appliances such as oil stoves and stoves. In addition, a reinforcing core was inserted between the heat-resistant combustion wicks connected to the upper end of the fuel wick.
- It is known from Publication No. 47325, and there is also one in which reinforcing paper is attached to the fuel wick with glue.
It is known from Publication No. 47-30269.

Problems that the invention aims to solve By the way, compared to woven cores, the above knitted cores have poor shape retention, are soft, and have weak stiffness, so even when attached to a core holder, the dimensions are not stable, and moreover, the core cannot be moved up and down repeatedly. As a result, the installation position was misaligned, resulting in problems such as poor fire extinguishing, disaster prevention, and incomplete combustion.

In addition, as disclosed in Japanese Utility Model Publication No. 56-47325, in which a reinforcing core is interposed between the heat-resistant combustion wick connected to the upper end of the fuel wick, the upper end of the heat-resistant combustion wick and the reinforcing core are inserted during dry firing. The degree of burnout differs from the upper end of the wick during use, making it impossible to achieve uniform combustion over a long period of time and requiring frequent replacement of the wick, which is uneconomical. In addition, as disclosed in Japanese Utility Model Publication No. 47-30269, reinforcing paper is attached to the fuel wicking core with glue, and the warp threads forming the fuel wicking core are attached to the reinforcing paper with glue. Because of this, it is not suitable for mass production, and the glue used to attach the reinforcing paper and warp threads is also attached to unnecessary parts, making it expensive. The reinforcing paper that was used did not allow petroleum to penetrate smoothly into the attached warp threads, and the warp threads and the reinforcing paper were not glued together incompletely, causing both to separate, resulting in defective products. .

This invention solves the above problems and aims to provide a wick for a combustion appliance that is convenient to use.

Means for Solving the Problems The wick for combustion appliances of this invention to achieve the above object consists of multiple threads of arbitrary thickness such as cotton fibers having good fuel absorption properties so as to have a constant thickness. The collected weft yarns 1 are repeatedly folded and arranged to a certain length, and an oil-resistant, water-resistant, non-stretchable reinforcing plate 2 such as kraft paper is overlapped with the reinforcing plate 2 to form multiple rows of thin warp yarns 3, 3 together with the reinforcing plate 2. ... to form a core knitted fabric 4, and the core knitted fabric 4 has an upper wide part 5 having warp threads 3, 3... and an intermediate wide part 6 without warp threads 3, 3... A narrow hem width part 7 with warps 3 and 3 is provided, and the reinforcing plate 2 located in the intermediate wide part 6 is removed to form a bending part 8, and the reinforcing plate 2 is further provided with a large number of through holes 9, 9. ... to form a fuel wick 10, and a heat-resistant combustion wick 11 is connected to the upper end of the combustion wick 10 via a connecting part 12.

Embodiment An embodiment of this invention will be explained below with reference to the drawings. 1 is a knitting yarn, in which a plurality of yarns of arbitrary thickness such as cotton fibers with good fuel absorption properties are assembled to have a constant thickness. The weft yarns 1 are repeatedly folded and arranged to a certain length, and an oil-resistant, water-resistant, non-stretchable reinforcing plate 2 such as kraft paper is interposed, and together with the reinforcing plate 2, multiple rows of thin warp yarns 3, 3, etc. are integrated. A core knitted fabric 4 is formed by knitting and stitching, and the core knitted fabric 4 has warps 3, 3.
An upper wide part 5 with..., an intermediate wide part 6 without warps 3, 3, and a narrow hem part 7 with warps 3, 3
and a reinforcing plate 2 located in the intermediate wide part 6.
is removed to form the bending portion 8, and a large number of through holes 9, 9... are bored in the reinforcing plate 2 to form the fuel suction core 10.
and a heat-resistant combustion wick 1 at the upper end of the fuel suction wick.
1 are connected through a connecting part 12, and the ones shown in FIGS. 1 to 3 have the weft yarns 1 arranged in two rows to form a double knit, with a reinforcing plate 2 interposed in between. The warp threads 3, 3... are integrated with the reinforcing plate 2.
In the case shown in Figures 4 to 6, the weft threads 1 are arranged in two rows to form a double knit.
A reinforcing plate 2 is superimposed on one side of the reinforcing plate 2, and the reinforcing plate 2 is knitted together with the warp threads 3, 3, . . . . Further, as shown in FIGS. 2 and 5, after knitting together the reinforcing plate 2 over the entire surface of the core knitted fabric 4, it is only necessary to cut and remove the reinforcing plate 2 of the bending part 8. When removing the reinforcing plate 2, since the needle holes for knitting and stitching are provided in series and continuously protruding, the reinforcing plate 2 can be easily removed by cutting it along the needle holes. The fuel suction wick 10 thus formed is either a flat core and a heat-resistant combustion wick 11 is connected to the upper part, or a vertical connection part 16 is further provided as shown in the figure to form a cylindrical core. Further, 13 is a reinforcing tape that covers the connecting portion 12 between the fuel wick 10 and the heat-resistant combustion wick 11. Further, 14 is a lead holder, 15 is a retaining claw provided on the lead holder 14, and 16 is a retaining claw provided on the lead holder 14.
2 is a vertical connection portion, and 20 is a core of a conventional product.

Effects of the invention This invention has the above structure and has the following effects.

(1) The fuel wick 10 is made by integrally knitting the weft 1 and the reinforcing plate 2, which are repeatedly folded to a certain length, with the warp threads 3, 3, etc. 3, the core knitted fabric 4 is reliably bonded, and the shape retention is significantly strengthened by reinforcing the entire body, making it stiffer and extremely durable, which can withstand long-term use.

(2) When attached to the lead holder 14, the retaining pawl 15 is inserted into the reinforcing plate 2, so even when the lead is moved up and down repeatedly, the lead 20 and the lead holder are held together like the conventional product shown in Fig. 8. 14, so troubles such as poor extinguishing, standing flames, and incomplete combustion can be eliminated.

(3) Since there is no reinforcing plate 2 in the bending/stretching part 8, there is no problem when bending/stretching the upper and lower parts of the core.

(4) Since the reinforcing plate 2 is integrally knitted into the narrow hem width part 7, defects such as deformation due to tension and contraction of this part are eliminated, and uneven fuel suction and firepower adjustment are avoided. It is possible to prevent problems such as poor lifting and lowering.

(5) No separate process is required when attaching the reinforcing plate 2;
When knitting and binding, it is possible to simultaneously pierce the fabric with a knitting needle and knit it integrally, making it possible to mass-produce uniform products without increasing costs.

(6) Weft yarn 1 arranged by repeatedly folding back to a certain length
and the reinforcing plate 2 are integrally knitted with the warp threads 3, 3, etc., so there is no possibility of quality changes over time due to long-term storage or long-term use of the product, and there is no chance of defective products due to dimensional irregularities. It can also be prevented from occurring.

(7) Since a large number of through holes 9, 9... are bored in the reinforcing plate 2, the oil permeates smoothly into the weft threads 1 forming the fuel suction core 10, and suction is performed evenly, resulting in uneven combustion. There is no such thing.

(8) Since the reinforcing plate 2 is not superimposed on the heat-resistant combustion wick 11, there is no risk that the upper end of the heat-resistant combustion wick 11 will become uneven and combustion will not be performed uniformly during dry firing.
