Description

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

《Prior art》 As shown in Figures 5 and 6, glass
Thick warps 30 made by simply bundling or twisting cotton or other fibers are arranged horizontally to form a warp layer 31,
Glass fiber felt-like fiber layer 3 on both the front and back sides
A core for a combustion appliance is known in which the glass fibers of the felt fiber layers 32, 32 are polymerized and entwined with the thick warp threads 30 arranged in parallel by needle punching (see Japanese Patent Publication No. 49-36170). ).

In addition, as shown in FIGS. 7, 8, and 9, a heat-resistant synthetic resin adhesive is applied around the front and back sides or one side of the warp row 40, which is prepared by warping warp groups made of arbitrary yarn materials. A wick for a liquid combustion appliance made of only a fabric 42 in which weft threads 41 made of fibers such as glass or synthetic inorganic fibers whose surface portions are impregnated in advance are wound around them at appropriate pitches or meandered back and forth to form layers, and both warp and weft threads are bonded together. is known (see Utility Model Publication No. 46-23634).

Further, as shown in FIG. 10, a wick for a liquid combustion appliance is known, which is formed using a plurality of nonflammable single fibers 51 having a space 50 in the axial direction up to the upper end of the wick 52 (Japanese Utility Model Publication No. 48-18598). (see publication).

<<Problems to be solved by the invention>> By the way, the wick for a combustion appliance shown in FIGS. 5 and 6 has felt-like fiber layers 32, 32 of glass fiber.
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 many separation gaps 3 are created.
3, 33... are formed and the thick warp threads 30 are arranged in parallel.
The warp layer 31 formed by the above-mentioned glass fiber felt-like fiber layers 32, 32 come into contact with each other and come apart, and furthermore, the warp threads 30 are deformed and the dimensions are unstable when the device is attached, resulting in poor fuel suction effect. The raising is not done evenly and becomes uneven, and the flame is not evenly aligned. Furthermore, in the warp layer 31 formed with thick warp threads 30, the warp threads 30 become uneven when the core is raised and lowered, so it is difficult to adjust the firepower by raising and lowering the core smoothly. There were disadvantages such as the inability to carry out 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 be inserted between the adjacent large diameter warp threads 30, 30, and the force that causes the large diameter warp threads 30, 30 to separate 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, but the suction of oil through the warps 30 with a large diameter is uniform on average. Furthermore, it is impossible to uniformly supply oil to the felt fiber layers 32, 32 through the warp threads 30 over the entire surface, which results in uneven fuel suction and uneven supply. It had drawbacks such as the inability to carry out combustion.

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.

In addition, the wicks for liquid combustion appliances shown in FIGS. 7, 8, and 9 are formed only of the fabric 42, and oil cannot be quickly sucked up to the upper end of the wick, making it impossible to ignite quickly. Also, when the core is moved up and down repeatedly, the claws of the core holding cylinder that dig into the fabric 42 may cut the warp rows 40 and the weft threads 41, or loosening may occur between the claws and the fabric 42 that has cut into the fabric 42, making it difficult to move the core up and down smoothly. This was not carried out properly, resulting in drawbacks such as poor combustion.

Also, the wick for the liquid combustion appliance shown in Fig. 10 is wick 5.
Since it is formed using a plurality of non-combustible single fibers 51 having a space 50 up to the upper end of the fuel, it also absorbs water mixed in the fuel, causing incomplete combustion and producing soot, which is undesirable from a sanitary standpoint. There were some shortcomings.

This idea solves the above problems, and it does not suck up even the water mixed in the fuel and interfere with combustion, and the fuel can be sucked up efficiently and evenly. It is possible to smoothly adjust the heating power by raising and lowering the wick to avoid uneven combustion, and it is possible to mass produce non-woven interlining at low cost. A convenient wick for combustion appliances that allows for a large height (distance) to the combustion part, prevents liquid fuel from being heated to high temperatures, and allows safe combustion to continue. The purpose is to obtain.

<Means for Solving the Problems> In order to achieve the above object, the wick for a combustion appliance of this invention has a structure in which the lower edge 6 of the heat-resistant core part 3 and the upper edge 7 of the fuel suction core part 5 are joined. In the wick for a combustion appliance in which the joint part 8 is formed, the heat-resistant core part 3 is made of heat-resistant fiber such as glass fiber, and the fuel wicking core part 5 is made of a material with good fuel wicking properties. A large number of non-heat-resistant long fibers 11 having a cavity 1 in the axial direction and previously subjected to lipophilic water repellent treatment are arranged in the same direction above and below and bonded to each other via an adhesive to form a long fiber layer 9, Non-heat-resistant short fibers formed from a random web of non-heat-resistant short fibers that are made of a material with good fuel wicking properties and have cavities 1 in the axial direction on both the front and back surfaces of the long fiber layer 9 and have been previously subjected to oleophilic and water-repellent treatment. It is formed by polymerizing the random web layers 4, 4 and integrally joining the long fiber layer 9 and the non-heat resistant short fiber random webs 4, 4 by needle punching.

<<Example>> An example of this invention will be described below with reference to the drawings. Reference numeral 3 denotes a heat-resistant core portion formed of heat-resistant fiber such as glass fiber.

Further, 5 is a fuel wicking core, which is made of a material with good fuel wicking properties and has a cavity 1 in the axial direction, and a large number of non-heat resistant long fibers 11 which have been previously subjected to oleophilic and water repellent treatment are arranged in the same direction above and below. are arranged and adhered to each other with an adhesive to form a long fiber layer 9, and the long fiber layer 9 is made of a material with good fuel absorption properties and has a cavity 1 in the axial direction on both the front and back surfaces of the long fiber layer 9, and is previously oleophilic and repellent. Polymerize the non-heat-resistant short fiber random web layers 4, 4 formed from a water-treated non-heat-resistant short fiber random web, and combine the long fiber layer 9 and the non-heat-resistant short fiber random web layers 4, 4 by needle punching. They are formed by integrally joining them.

8 is the lower edge 6 of the heat-resistant core 3 and the fuel suction core 5.
This is a joint where the upper end edge 7 of the joint 8 is joined via a suture thread 2, and 10 is a reinforcing tape that covers the joint 8.

In addition, the non-heat-resistant long fibers 11 and the non-heat-resistant short fiber random webs having the hollow portion 1 are made of rayon, nylon,
Non-heat resistant long fibers 11 and non-heat resistant short fibers are made of materials such as polyester, kyupra, acetate, acrylic, etc., and by changing the shape of the holes in the spinneret (not shown), as shown in FIG. The cross-sectional shape of the random web and the cross-sectional shape of the cavity 1 can be changed.

《Operations and Effects of the Idea》 According to this invention, the following effects can be obtained.

The upper edge 7 of the fuel suction core 5 and the lower edge 6 of the heat-resistant core 3 are joined to form a joint 8, and the heat-resistant core 3 is provided to prevent burnout due to combustion and ensure long-term use. It is something that can be endured.

Since the fuel wicking core part 5 is made of a non-woven fabric with non-heat resistant short fiber random web layers 4, 4 on the front and back sides, fraying does not occur at the cutting edges, and it is possible to cut by punching etc., resulting in variations in dimensions. It can be manufactured uniformly without any blemishes.

Since the fuel wicking core 5 has non-heat-resistant short fiber random webs intertwined randomly, the claws of the core holding cylinder can be accurately locked without damaging the non-heat-resistant short fiber random webs, thereby preventing dimensional deviations during use. The lifting and lowering operations of the core can be performed smoothly without any occurrence.

The long fiber layer 9 provided in the fuel wicking core 5 is formed by arranging a large number of non-heat resistant long fibers 11 in the same direction above and below and adhering them to each other with an adhesive. , compared to the one formed of twisted yarn, the same effect as having more capillaries passed through than the conventional product can be obtained, and the non-heat resistant long fibers 11 forming the long fiber layer 9 also have hollow portions 1 in the axial direction. Capillarity is promoted in this cavity 1, and by having a high fuel wicking speed, it is possible to generate a high calorific value with high calorie combustion, and furthermore, the fuel wicking property is good. The non-heat-resistant short fiber random web layers 4, 4 formed of a non-heat-resistant short fiber random web that has a cavity 1 in the axial direction and has been subjected to lipophilic water repellent treatment in advance are a conventional non-heat-resistant short fiber random web layer. As the fuel suction distance becomes longer, the amount of fuel retained increases significantly. Therefore, the fuel absorption layer 9 made of non-heat resistant long fibers 11, which is made of a material with good fuel suction characteristics and has a cavity 1 in the axial direction. The upper distance can be further increased, and the height between the liquid level of the fuel in the fuel tank and the combustion part can be increased in base tank type combustion appliances. In addition to avoiding the danger of the fuel being heated to high temperatures, the base tank can be made deeper, allowing it to store a large amount of fuel, making it possible to burn for long periods of time without having to add fuel midway through, creating a combustion device that is convenient to use. It is something that can be provided.

In base tank type combustion appliances with a fuel tank located at the bottom, the fuel level in the fuel tank decreases as the combustion time increases, but even if the fuel level decreases, the fuel suction does not decrease. , the firepower never weakens.

Non-heat resistant long fiber 1 with good wicking properties for many fuels
This makes it easier on average to absorb fuel in the long fiber layer 9 made of 1, but there is a problem that the fibers easily tear because there is little interlacing of the fibers. By the way, the non-heat-resistant short fiber random web layers 4, 4 are polymerized and integrally formed on both sides of the long fiber layer 9 by needle punching, making it tough and preventing the conventional combustion shown in FIGS. 5 and 6. Unlike instrument cores, there are no variations in dimensions such as inconsistent thickness,
Also, troubles caused by dimensional changes during use can be eliminated.

The non-heat resistant long fibers 11 that formed the long fiber layer 9 and the non-heat resistant short fiber random web that formed the non-heat resistant short fiber random web layer 4 were previously subjected to lipophilic water repellent treatment, making the finished product water repellent. This prevents uneven treatment that occurs when the treatment is applied only to the surface and does not penetrate into the interior, resulting in uniform wicking.
A product that can be used without any change over a long period of time is obtained, and furthermore, the upper edge 7 of the fuel wicking core 5 and the lower edge 6 of the heat-resistant core 3 are joined to form a joint 8, so that the cavity 1 is connected to the upper edge of the heat-resistant core 3. This, combined with the fact that no soot is formed, prevents the generation of soot due to water absorption and allows for smooth combustion.
