Description

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

<Prior art> Conventional wicks for combustion appliances of this type include a heat-resistant combustion wick made of glass fiber or a thick fabric of glass fiber and carbon fiber blend on the upper part of the combustion wick made of cotton thread or a thick fabric of cotton and rayon blend. It is known that the interlining is formed into a flat or cylindrical core by connecting the parts. In addition, a core for a combustion appliance in which a felt-like fiber layer is polymerized on the entire surface of a textured fabric made of woven or knitted fabric using warp and weft yarns made of fibers mainly composed of glass fibers is disclosed in, for example, Japanese Utility Model Publication No. 140732/1983. Are known.

<Problems to be Solved by the Invention> However, the former wick for combustion appliances having such a configuration had the following drawbacks.

(1) Productivity is extremely low and inefficient because production relies on old-fashioned special looms.

(2) In particular, the number of looms is limited because the combustion wicking section is made of extremely thick cotton yarn, such as 8-strand 10-count cotton yarn, and is narrow and has a special structure.
Furthermore, because the area used is large, there is often a shortage of supply.

(3) Dimensional variations are likely to occur, resulting in a high defective rate, and in addition to shrinking during use, the device's core guide tube is likely to get stuck, leading to problems such as improper lifting and lowering of the core.

(4) It tends to fray when cut, so it is necessary to apply fraying prevention processing such as overstitching the edges or applying adhesive.

(5) Fuel suction efficiency deteriorates due to interlacing of warp and weft threads.

(6) Due to the weaving, the surface is uneven, and there are gaps between the warp and weft yarns, which makes it difficult to adhere tightly to the core guide tube of the device, creating an unnecessary draft effect between the inside of the tank and the outside air. In addition to impairing fuel performance and fire extinguishing performance, oil leakage increases when equipment falls over.

(7) It is difficult for the reinforcing tape to adhere tightly, and the various markings (manufacturer name, model number, dimensions, etc.) become unclear and difficult to read.

In addition, as an attempt to improve the productivity of fabrics, a knitted core using a weft insertion warp knitting machine (Ratucel warp knitting machine) has been proposed, but since the fabric is not thick enough, it is necessary to overlap several layers, In addition to the drawback that the fuel required to maintain combustion cannot be sucked up unless measures such as double knitting are used, there is a gap in the vertical direction when attached to a device, making it more difficult than the above-mentioned woven wick. Combustion performance and digestion performance deteriorate due to unnecessary draft action, and the amount of oil leakage increases further.
There are various disadvantages such as the warp binding threads being cut by the claws of the core holding cylinder and friction when the core is raised and lowered, causing the weft to fall apart and becoming unusable, and the core as a whole having poor rigidity resulting in a weak product. However, none of them were desirable. In addition, the latter wick for combustion appliances has a felt-like fiber layer that is polymerized into a textured woven or knitted fabric using warp and weft yarns that are mainly made of glass fibers, resulting in poor fuel wicking efficiency. It was not possible to adjust the firepower by raising and lowering the flame, and the flame was not evenly aligned due to deformation of the core and unstable dimensions when the device was attached.

This invention solves the above-mentioned problems, and provides an interlining for combustion appliances that can be mass-produced at low cost and has good fuel suction efficiency and excellent rigidity, and is convenient to use. The purpose is to

<Means for Solving the Problems> In order to achieve the above object, the interlining for a combustion appliance of the present invention includes a heat-resistant short fiber random web layer 2 on both upper surfaces of a substrate 1 formed of a metal net plate. 2 is polymerized to form a heat-resistant fiber layer 7, and furthermore, a bent joint surface 6 is provided on both lower surfaces of the substrate 1 and below the lower both surfaces without the substrate 1 intervening, and the non-heat-resistant short fibers have good fuel wicking properties. The random web layers 3, 3 are the lower edge 4 of the heat-resistant staple fiber random web layers 2, 2,
4 and the non-heat resistant short fiber random web layers 3, 3 are polymerized so that the upper edges 5, 5 of the non-heat resistant short fiber random web layers 3, 3 are joined to form a fuel wicking fiber layer portion 8.

<Example> An example of the present invention will be described below with reference to the drawings. 1 is a substrate formed of a metal net plate, and heat-resistant short fiber random web layers 2, 2 are polymerized on both upper surfaces to form a heat-resistant fiber layer portion. 7, and a bent joint surface 6 extending below both lower surfaces of the substrate 1 and without the substrate 1 intervening therebetween, and non-heat resistant short fiber random web layers 3, 3 having good fuel wicking properties, The lower edge 4 of the short fiber random web layer 2, 2,
4 and the non-heat resistant short fiber random web layers 3, 3 are polymerized such that the upper edges 5, 5 of the non-heat resistant short fiber random web layers 3, 3 are joined to form a fuel wicking fiber layer portion 8.

In addition, the substrate 1 and the heat-resistant short fiber random web layer 2,
2, and the substrate 1 and the non-heat-resistant short fiber random web layers 3, 3 are polymerized and integrated, and the non-heat-resistant short fiber random web layers 3, 3 have a bending joint surface 6.
Polymerization and integration can be carried out by intertwining short fibers by needle punching, sewing, or bonding with adhesive, etc., and then cutting the interlining A into an arbitrary size and using it as a flat core. It is used as a cylindrical core by joining into a cylindrical shape.

In addition, the material of the short fiber random web layers 2, 2 is selected by carefully considering the fuel absorption characteristics and heat resistance. For example, the material is mainly made of heat resistant fibers such as glass, carbon, ceramics, asbestos, etc. The short fiber random web layers 3, 3 may be made of non-heat resistant fibers such as cotton, linen, or cotton, which have good fuel absorption properties.

In addition, in FIG. 5, one of the heat-resistant short fiber random web layers 2, 2 is thinned, the substrate 1 is used as a cathode, and a spark discharge is caused between the heat-resistant short fiber random web layer 2 and the discharge anode 9, and an igniter is generated. It is possible to perform discharge ignition such as.

<Actions and Effects of the Invention> According to this invention, the following effects can be obtained.

(1) Since the interlining A can be produced at high speed without the need for a loom, knitting machine, etc., interlining material with higher productivity and lower cost than conventional methods can be obtained.

(2) Since it is a non-woven fabric, fraying does not occur at the cut edges, and it can be cut by punching, etc., and it can be manufactured uniformly without variations in dimensions.

(3) Dimensional variations do not occur, and troubles caused by dimensional changes during use can be eliminated.

(4) Since the substrate 1 is made of a metal mesh plate for the purpose of reinforcement, rigidity is imparted and the core body is deformed.
Eliminates drawbacks such as dimensional instability when installing equipment,
There is no possibility that the flame will not be uniformly aligned.

(5) Since the surface has less unevenness, a reinforcing tape is attached to the joint between the heat-resistant short fiber random web layers 2, 2 and the non-heat-resistant short fiber random web layers 3, 3 (not shown)
In addition to improving adhesion, various markings (manufacturer name, model number, dimensions, etc.) can be clearly marked, and when attached to a device, the gaps between the fibers and the device are reduced, improving combustion performance.
Fire extinguishing performance can be improved.

(6) 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 will not occur during use.

(7) Even though the material of the substrate 1 is metal, since it is made of a mesh board, the short fibers of the heat-resistant short fiber random web layer 3, which are polymerized on both sides of the mesh board, do not get entangled and accidentally separate, so it can last for a long time. Withstands use.

(8) The non-heat-resistant short fiber random web layers 3, 3 having good fuel wicking properties are placed between the lower edges 4, 4 of the heat-resistant short fiber random web layers 2, 2 and the upper ends of the non-heat-resistant short fiber random web layers 3, 3. Since the fuel wicking fiber layer portion 8 is formed by polymerizing so that the edges 5, 5 are joined, fuel is sufficiently supplied to the heat-resistant fiber layer portion 7, and strong firepower can be obtained.

(9) Since the bending joint surface 6 is provided extending downward from both sides of the lower part without the substrate 1 intervening, a split for opening the hem, a split for bending and stretching, etc. are provided, making it suitable for upper and lower cores, and the heating power can be adjusted easily. be able to.
