Description

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

《Prior art》 Conventionally, as a core for a combustion appliance, thick warp threads made by simply bunching or twisting glass, cotton, or other fibers are arranged horizontally, and felt-like fiber layers of glass fiber are polymerized on both the front and back sides to form a needle punch. For example, the creation of cores for combustion appliances by intertwining the glass fibers of the felt-like fiber layer with thick warp threads arranged in parallel was developed by Tokko Sho, for example.
It is known from the publication No. 49-36170.

《Problems to be solved by the invention》 By the way, since this product has many fuzzy fibers exposed and intersecting on the surface, the core mounting line, the trademark of the device manufacturer, the product number, etc. are printed on the core surface. It's hard. The fluffy fibers get entangled with the wick up/down operation part, making the wick up and down movement uneven. When the core is attached to a device and the core is moved up and down, the frictional resistance between the core and the container body is large, causing the core to move up and down unevenly or to be misaligned, making it difficult to extinguish the fire. The parallel thick warp threads and the glass fiber felt-like fiber layer do not come together to prevent separation, but instead touch and separate, causing the warp threads to deform and cause dimensional instability when the device is attached, resulting in fuel wicking. There were drawbacks such as unevenness and uneven fire distribution.

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

<Means for Solving the Problems> To achieve the above object, the wick for a combustion appliance of this invention has a long fiber layer 2 in which a large number of long fibers 1 are aligned in the fuel suction direction, and a long fiber layer 2 in which short fibers are randomly arranged. A non-woven fabric body 4 is formed by laminating the web layers 3 alternately so as not to peel off, and the fluffy fibers 6 on the surface 5 of the non-woven fabric body 4 are heat-shrinked and hardened to form a smooth surface 7. A core body 8 is formed.

<<Example>> An example of this invention will be described with reference to the drawings. In FIG. 1, 9 indicates a cylindrical core, and a heat-resistant combustion core 11 is integrally connected to the upper part of a fuel suction core 10. ing.

4 is a non-woven fabric, made of rayon acetate.
Nylon, acrylic, polyester, vinylon,
The long fiber layer 2 consists of a large number of long fibers 1 made of polyethylene, polypropylene, glass fiber, polyvinyl chloride, aramid, carbon fiber, etc. alone or in a mixture, aligned in the fuel absorption direction, and the long fiber layer 2 is made of long fibers 1 made of polyethylene, polypropylene, glass fiber, polyvinyl chloride, aramid, carbon fiber, etc.
Nylon, acrylic, polyester, vinylon,
It is formed by alternately laminating short fiber random web layers 3 made of polyethylene, polypropylene, polyvinyl chloride, aramid, cotton, linen, wool, etc. alone or in a mixture so as not to peel off. As a means, as shown in Figs. 3 and 4, both outer surfaces of the long fiber layer 2 are laminated with short fiber random web layers 3, 3 interposed between the long fiber layer 2, or as shown in Figs. 5 and 4. They may be alternately laminated to form multiple layers as shown in FIG. 6.

Further, as a means of integration, for example, the short fibers 13 constituting the web may be penetrated through the long fiber layer 2 by needle punching to uniformly integrate them, or the short fibers 13 constituting the web may be uniformly integrated with the long fiber layer 2 by stitch bonding (not shown). It is also possible to integrate the fiber random web layers 3 by sewing them together with a sewing thread. Numeral 6 denotes fluffy fibers that are fluffed on the front surface 5 and back surface 12 of the nonwoven fabric body 4.

Further, 8 is a core body having a smooth surface 7 by heating the fluffy fibers 6 of the nonwoven fabric body 4 at an appropriate temperature to shrink and harden them so that the front surface 5 or the front surface 5 and the back surface 12 are smooth.

Although various heating means can be considered, fluffy fibers 6
may be melted and softened by heating with hot air to shrink and harden, or a heating plate may be brought close to or in contact with the nonwoven fabric 4, and the nonwoven fabric 4 may be further inserted between heated rollers. Appropriate measures shall be taken accordingly.

Further, in the illustrated embodiment, the fuel suction core 10 is formed of the core body 8, but the heat-resistant combustion core 1
1 can also be formed of a core 8.

<<Operations and Effects of the Device>> This device has the following effects due to the above-mentioned configuration.

Since interlining can be produced at high speed without the need for looms, knitting machines, etc., interlining can be obtained with higher productivity and at lower cost than in the past.

Since the short fiber random web layers 3, 3 are provided and made of non-woven fabric, fraying at the cut end of the core body 8 does not occur during molding, and the core body 8 can be manufactured uniformly without variation in dimensions.

Since the short fibers are randomly intertwined, the claws of the core holding cylinder can be accurately locked without damaging the fibers, so dimensional deviations do not occur during use.

The core body 8 in which a large number of long fibers 1 are oriented in the fuel suction direction has the same effect as having a large number of capillary tubes running above and below, and also has a high fuel suction speed, thereby generating a high calorific value. Furthermore, since it is possible to increase the height between the liquid level of the liquid fuel in the fuel tank and the combustion section, it is possible to avoid the risk of the liquid fuel in the fuel tank being heated to a high temperature.

Since the surface 5 of the core body 8 has a smooth surface 7 where the fluffy fibers 6 are exposed and has no fluff, it is possible to print the product number, the trademark of the device manufacturer, the core installation line, the manufacturer's name, and display items specified by JIS. Since it can be done clearly and easily, it is easy for consumers to present the actual product and purchase it when replacing the core.

Since the surface 5 of the core body 8 is smooth, when the core body 8 is attached to an instrument, the frictional force with the device body is reduced and the core moves up and down smoothly.

Since the surface 5 of the core body 8 is smooth and the fluffy fibers 6 do not get entangled with the upper and lower operation parts of the core, it is possible to prevent the upper and lower parts of the core from becoming uneven, making it impossible to extinguish the fire, etc.
