Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a wick for combustion appliances such as oil stoves and oil stoves that use kerosene as fuel.

<<Prior Art>> Conventionally, as shown in FIGS. 5 and 6, thick warps 30 made by simply bunching or twisting glass, cotton, or other fibers are arranged horizontally in parallel to form a warp layer 31.
Glass fiber felt-like fiber layer 3 on both the front and back sides
A wick for a combustion appliance is known in which the glass fibers of felt fiber layers 32, 32 are polymerized and needle punched so that they are arranged horizontally and entwined with thick warp threads 30 (Japanese Patent Publication No. 49-36170). reference).

In addition, as shown in FIG. 7, warped warp rows 40 of glass fiber yarn, natural fiber yarn, synthetic fiber yarn, etc.
The weft 41 of the same kind of yarn impregnated with an adhesive is surrounded or simply layered, and the fabric 42 formed by gluing the warp and weft yarns is sewn into a cylindrical shape with the warp in the warp direction, and the wall has an inverted U cross section. The lower end edge 46 of the upper core 45 formed into a cylindrical shape from a flame-resistant material made of carbon fiber thread is brought into contact with the folded edge 44 of the upper end of the lower core 43, which is formed by folding the inner and outer double cylinders to form a letter shape. A wick for a liquid combustion appliance is known in which the wick is sewn with a heat-resistant fiber thread or the like (see Japanese Utility Model Publication No. 46-23635).

<<Problems to be Solved by the Invention>> By the way, the wick for a combustion appliance illustrated in FIGS.
A special shaped needle having a bulge at the tip is polymerized on both the front and back sides of a warp layer 31 formed by horizontally paralleling thick warp threads 30 made by simply bundling or twisting glass, cotton, or other fibers. Since the glass fibers of the felt-like fiber layers 32, 32 are entwined with the horizontally parallel thick warps 30 by needle punching, the adjacent thick warps 30 are separated and a large number of detached empty sections 3 are created.
3, 33... are formed, and the warp layer 31 formed by the parallel thick warp threads 30 and the glass fiber felt-like fiber layers 32, 32 come into contact with each other and separate from each other, and further the warp threads 30 are deformed and the dimensions when the device is attached are changed. Due to instability, the suction effect of the fuel is poor and the suction is not done evenly, resulting in uneven flames and the flame is not uniform.Furthermore, the warp layer 31 formed of thick warp threads 30 has a problem in that the warp threads 30 are not aligned properly when the core moves up and down. There were drawbacks such as the unevenness and the inability to smoothly raise and lower the wick to adjust the firepower. That is, in the case shown in FIGS. 5 and 6, the large diameter warp 30 is made by simply bundling glass fibers or the like in one direction, or the large diameter warp 30 is made by twisting this bundled material. Therefore, when the needle is inserted by needle punching, the swollen part of the needle tip hits the large diameter warp threads 30 and cannot pierce, and a strong force acts on the warp threads 30, causing the warp threads 30 and the felt fiber layer 32 to Also, when the needle is inserted by needle punching, the bulging part of the needle tip cannot pierce between the adjacent large diameter warp threads 30, 30, and the force that separates the large diameter warp threads 30, 30 is generated. The thickness of the warp layer 31, which is formed by arranging large diameter warps 30, differs depending on the insertion point of the needle by needle punching, and the degree of entanglement between the warp layer 31 and the felt-like fiber layers 32, 32 differs. It is something.

In addition, since the warp layer 31 is formed by arranging a large number of warps 30 with a large diameter, the thickness is not uniform over the entire surface, and the fuel is sucked up evenly on average through the warps 30 with a large diameter. Furthermore, it is not possible to uniformly supply fuel to the felt fiber layers 32, 32 through the warp threads 30 over the entire surface, which results in uneven fuel suction and prevents uniform combustion. There were disadvantages such as the inability to carry out

Furthermore, since the swollen part of the needle tip gets in the way of this needle insertion, the felt fiber layers 32, 32 and the warp layer 3
1 cannot be sufficiently pierced from the front surface to the back surface, the fibers cannot be integrated by intertwining in fact, and the layers may peel off, making it impractical.

The wick for a liquid combustion device shown in FIG. 7 has a warp row 4, that is, a warp row formed of threads made by stretching fibers long and thin, and twisting them, and a weft thread 40, that is, fibers impregnated with an adhesive. Stretch it out long and thin,
Warp yarns impregnated with adhesive are surrounded or simply layered on twisted yarns, warp rows 40 and weft yarns 41 are adhered to form fabric 42, and this fabric 42 is attached to warp rows 4.
0 is folded back to form an inverted U-shaped cross section in the warp direction to form a lower core 43, and further, the lower end edge 46 of the upper core 45 is attached to the folded edge 44 of the upper end of the lower core 43.
As a result, the upper end folded edge 44 and the lower edge 46 of the upper core 45 were not joined sufficiently, and the warp rows were slightly compressed by the folding, which hindered fuel suction. The fuel cannot be sucked up to the upper end of the 45 quickly, so it cannot be used for large models that require large firepower, and furthermore, it cannot be ignited quickly.

In addition, when the core is moved up and down repeatedly, the claws of the core holding cylinder that cut into the lower core 43 or the upper core 45 may cut the warp and weft of the lower core 43 or the upper core 45, or the lower core 43 and the upper core 45 that cut into the claws. There were drawbacks such as loosening between the wick and the wick, making it difficult to move the wick up and down smoothly, resulting in poor combustion.

This invention solves the above-mentioned problems. Fuel can be sucked up efficiently and evenly, there is no uneven combustion, and a wick having a desired thickness can be supplied depending on the model. It is easy to do, and the heating power can be adjusted smoothly by raising and lowering the wick to prevent uneven combustion. Nonwoven interlining can be mass-produced at low cost. The height (distance) of the lamp can be increased, and it is possible to prevent the liquid fuel from being heated to high temperatures, which prevents delamination of the interlining material and causes poor fitting between the combustion appliance and the lamp wick. The object of the present invention is to obtain a wick for a combustion appliance that is convenient to use and can continue safe combustion.

≪Means for Solving the Problems≫ In order to achieve the above object, the wick for a combustion appliance of the present invention consists of a large number of heat-resistant fibers stretched in the same vertical direction and a large number of heat-resistant fibers bonded to each other with an adhesive. Several flexible sheet-like heat-resistant wide plates 12 made of long fibers are polymerized to form an upper heat-resistant long fiber layer 1, and heat-resistant short fiber random web layers 2, 2 are formed on both the front and back surfaces of the upper heat-resistant long fiber layer 1. At the same time, the upper heat-resistant long fiber layer 1 and the heat-resistant short fiber random web layers 2, 2 are integrally joined by needle punching to form the heat-resistant fiber layer 3, and the non-heat-resistant fibers are further added to the top and bottom of the same layer. A lower long fiber layer is formed by polymerizing several flexible sheet-like non-heat-resistant wide plates 13 made of non-heat-resistant long fibers that have good fuel wicking properties and are stretched long in the direction and bonded to each other via an adhesive. 9, and non-heat resistant short fiber random web layers 4, 4 having good fuel wicking properties are formed on both the front and back sides of the lower long fiber layer 9.
At the same time, the lower long fiber layer 9 and the non-heat-resistant short fiber random web layers 4, 4 are integrally joined by needle punching to form the fuel wicking fiber layer portion 5, and the heat-resistant fiber layer portion The cut lower end edge 6 of No. 3 and the cut upper end edge 7 of the fuel wicking fiber layer portion 5 are butted and joined via a suture thread 11 to form a joint portion 8.

≪Example≫ Hereinafter, an example of the present invention will be described with reference to the drawings. 1 is a flexible sheet-like sheet consisting of a large number of heat-resistant long fibers that are stretched long in the same vertical direction and bonded to each other via an adhesive. The upper heat-resistant long fiber layer is formed by polymerizing several heat-resistant wide boards 12 via the first polymerized wall surface portion 14, and heat-resistant short fiber random web layers 2, 2 are formed on both the front and back surfaces of the upper heat-resistant long fiber layer 1. At the same time, the upper heat-resistant long fiber layer 1 and the heat-resistant short fiber random web layers 2, 2 are integrally joined by needle punching to form the heat-resistant fiber layer portion 3.

Further, 9 is a flexible sheet-like non-heat-resistant wide plate 13 made of non-heat-resistant long fibers having good fuel wicking properties, which are made by stretching long non-heat-resistant fibers in the same vertical direction and bonding them together with an adhesive. The lower long fiber layer is formed by polymerizing several sheets through the second polymerized wall surface part 15, and on both the front and back sides of the lower long fiber layer 9, a non-heat resistant short fiber random web layer 4 having good fuel wicking properties, 4, and the lower long fiber layer 9 and the non-heat-resistant short fiber random web layers 4, 4 are integrally joined by needle punching to form the fuel wicking fiber layer portion 5.

Reference numeral 8 denotes a joint where the cut lower end edge 6 of the heat-resistant fiber layer section 3 and the cut upper end edge 7 of the fuel wicking fiber layer section 5 are butted and joined via a suture thread 11.

Furthermore, the materials of the upper heat-resistant long fiber layer 1 and the heat-resistant short fiber random web layer 2 are selected with careful consideration of heat resistance. The materials of the lower long fiber layer 9 and the non-heat-resistant short fiber random web layer 4 include rayon, cellulose acetate, polyamide, acrylic, polyester, polyvinyl formal, polyethylene, polypropylene, polyvinyl chloride, and polyvinyl chloride, all of which have good fuel absorption properties. It is made of non-heat resistant fibers such as aromatic polyamide, cotton, linen, wool, etc., either alone or in combination.

In addition, 10 in the figure is a suture thread 11 used to butt the lower edge 6 of the heat-resistant fiber layer 3 and the upper edge 7 of the fuel wicking fiber layer 5.
This is a reinforcing tape that covers the bonded portion 8 that is bonded via the .

<<Operations and Effects of the Invention>> According to the present invention, the following operations and effects can be obtained.

Heat-resistant short fiber random web layers 2, 2 are provided on the front and back sides of the heat-resistant fiber layer section 3, and non-heat-resistant short fiber random web layers 4, 4 are provided on the front and back sides of the fuel wicking fiber layer section 5. Since it is prepared, fraying does not occur at the cut end, and it can be cut by punching or the like, and it can be manufactured uniformly with no variation in dimensions.

Since the short fibers of the heat-resistant fiber layer 3 and the fuel wicking fiber layer 5 are randomly intertwined, the claws of the core holding cylinder can be accurately locked without damaging the short fibers, which may cause dimensional deviations during use. You can smoothly raise and lower the core without having to worry about it.

The upper heat-resistant long fiber layer 1 of the heat-resistant fiber layer section 3 and the lower long fiber layer 9 of the fuel wicking fiber layer section 5 are formed by simply stretching the fibers lengthwise, that is, in the vertical direction, unlike conventional products. Compared to a product made of twisted thread, it produces the same effect as having more capillary tubes than conventional products, and has a high fuel suction speed, which generates a high amount of heat. Furthermore, since it is possible to increase the height between the liquid level of the liquid fuel in the fuel tank and the combustion part, it is possible to avoid the risk of heating the inside of the fuel tank and the liquid fuel to high temperatures. It is.

The upper heat-resistant long fiber layer 1 is formed by polymerizing several flexible sheet-like heat-resistant wide plates 12 made of a large number of heat-resistant long fibers, and the sheet-like sheet-like material is made of a large number of non-heat-resistant long fibers that have good fuel wicking properties. The lower long fiber layer 9 is formed by polymerizing several non-heat resistant wide plates 13, each having the same thickness over the entire surface and facilitating fuel suction on average, but the fibers are mutually separated. There is a problem that it tears easily because there is little interlacing. However, heat-resistant short fiber random web layers 2, 2 are polymerized on both sides of the upper heat-resistant long fiber layer 1, which is formed by polymerizing several flexible sheet-like heat-resistant wide plates 12 made of a large number of heat-resistant long fibers. A non-heat-resistant short fiber random web layer is formed on both sides of the lower long fiber layer 9 formed by polymerizing several flexible sheet-like non-heat-resistant wide plates 13 made of non-heat-resistant long fibers that have good wicking properties for many fuels. 4 and 4 are polymerized and integrally formed by needle punching, it becomes strong and has no dimensional variations such as non-uniform thickness like the conventional wicks for combustion appliances shown in Figures 5 and 6. Also, troubles caused by dimensional changes during use can be eliminated.

In combustion appliances with a fuel tank located at the bottom, even if the fuel level in the fuel tank decreases as the combustion time increases, the suction of fuel does not decrease, so the firepower does not weaken.

Capillary action is also performed from the overlapping wall surface of the heat-resistant wide board 12 made by polymerizing several sheets and the overlapping wall surface of the non-heat-resistant wide board 13 made by polymerizing several sheets to promote fuel suction, and the number of sheets to be overlapped is selected according to the model used. In other words, in the case of large models that require large firepower, it is necessary to increase the suction amount of fuel, so by increasing the number of overlapping heat-resistant wide plates 12 and non-heat-resistant wide plates 13, the suction amount can be increased. It is possible to easily form products with different shapes and reduce manufacturing costs.

In conventional technology, the cut edges of the heat-resistant part and fuel suction part must be oversewn with an oversewing machine to prevent fraying, and the oversewing thread prevents the two edges from coming into contact with each other at the joint. This may impede the transfer of fuel between the parts, and the thickness of the cut edge increases due to the volume of the overdarning thread due to overdarning.
Although it sometimes caused problems in fitting the lamp wick and the combustion appliance, the cut lower edge 6 of the heat-resistant fiber layer 3
and the cut upper end edge 7 of the fuel wicking fiber layer 5 are simply butted and joined via the suture thread 11 to form a joint 8.
By forming this, it is possible to smoothly supply fuel from the fuel wicking fiber layer 5 to the heat-resistant fiber layer 3 without any hindrance. It does not reduce the supply of fuel to the layer 3, does not have the drawbacks such as not being able to be used in models that require large firepower like the conventional product shown in Figure 7, and is suitable for combustion equipment. There is no problem in fitting the lamp wick to the lamp wick, making it extremely convenient to use.
