Description

[Detailed description of the invention] ≪Industrial application field≫ The present invention is capable of reinforcing the whole product by interposing a reinforcing core and making it possible to obtain a uniform product with stable dimensions and shape. Speed up the fire cycle at the time of ignition to hasten the rise time for stable combustion,
The present invention relates to a wick for a combustion appliance that eliminates odor during initial combustion, reduces adhesion of impurities such as tar during use, can be used efficiently, and is easy to manufacture, and a method for manufacturing the same.

<<Prior Art>> As shown in FIG. 7, conventional wicks for combustion appliances have a heat-resistant combustion wick 30 connected to the upper part and a combustion suction wick part 32 to the lower part. As shown in Figure 8, two reinforcing cores 3
2 and 32 are arranged side by side with an intervening part 33, and the heat-resistant combustion part front weft 3 is made to converge to an appropriate thickness on the front and back surfaces.
4 and the heat-resistant combustion part back weft 35 are arranged in a zigzag pattern while being repeatedly folded, and the heat-resistant combustion part back weft 35 is arranged by repeatedly folding over the two reinforcing cores 32, 32 arranged in parallel. The heat-resistant combustion wick 30 of the wick for a combustion appliance is known in which the back weft 35 of the heat-resistant combustion part is cut from the middle part of the intermediate part 33, and a fluffy part 36 for fire surrounding is formed at the tip as shown in FIG. (Refer to Utility Model Application Publication No. 56-47325).

Further, as shown in FIG. 10, in a combustion wick 40 whose tip portion is made up of non-combustible fibers 38 and combustible fibers 39, the combustible fibers at the tip portion are removed by incubation with hot air, and the combustible fibers are removed from the combustion wick. A wick for combustion appliances with one end made rougher than the other end is known (Special Publication No. 52
-Refer to Publication No. 22682).

<<Problems to be Solved by the Invention>> By the way, in the wicks for combustion appliances shown in FIGS. 7, 8, and 9, the fluffy part 36 for fire surroundings provided at the tip forms the heat-resistant combustion wick 30. In order to do this, the fire-spinning fluffy portion 36 is formed of the same yarn as the burning section back weft 35 provided on the back side of the reinforcing core 32, so the fire-spinning speed becomes slow, and the fire-spinning fluffy portion 36 There were drawbacks such as impurities such as tar adhering to the fuel, making it impossible to carry out normal combustion smoothly.

Furthermore, the wick for a combustion appliance shown in FIG. 10 requires a special fabric in which non-combustible fibers 38 and combustible fibers 39 are woven into a relatively thick material, and also requires a process to burn out the combustible fibers 39 during initial combustion. However, when the combustion occurs, a foul odor and smoke are generated, causing a pollution problem, and other impurities adhere to the wick.Furthermore, the tip of the combustion wick 40 is made coarser than the other end, which causes combustibility. When the fibers 39 are burned out, the dimensions become unstable, and since there is no reinforcing core in the heat-resistant combustion part at the top of the core, the shape is unstable, the combustion flame becomes uneven, and smooth and quick fire rotation is not possible. There were some shortcomings.

This invention solves the above problems and is easy to manufacture, stable in size and shape over a long period of time, smooth and uniform oil suction with no unevenness in quality, and improved fire circulation during ignition. The object of the present invention is to obtain a wick for a combustion appliance that is convenient to use and that can be quickly and easily used.

<<Means for Solving the Problems>> The wick for a combustion appliance of the present invention for achieving the above object has a heat-resistant combustion wick 15 connected to the upper part and a fuel suction wick 16 connected to the lower part via the connection part 21. In the wick for a combustion appliance, the heat-resistant combustion wick 15 includes a large number of threads 1 made of heat-resistant fibers such as glass fibers and carbon fibers, and a small number of thin threads 11 made of heat-resistant fibers with a diameter smaller than that of the threads 1.

The upper ends are butt-sewn and connected.

<<Operations and Effects of the Invention>> The present invention has the above-described configuration, and provides the following effects.

Since the fluffy parts 7 for fire-spinning formed by cutting the thin threads 11, 11... are arranged in a rough and orderly protruding arrangement, less preheating energy is required, and the fire-spinning at the time of initial ignition is further accelerated, thereby preventing the generation of foul odors. prevent,
The rise time until normal combustion can be further shortened.

During combustion, the fluffy part 7 for fire surroundings formed of a small number of thin threads 11 with a smaller diameter than the large number of threads 1 is in a dry burning state from beginning to end, preventing the adhesion of impurities such as tar, and removing defective kerosene. It can be used without any change even during combustion.

By increasing or decreasing the fine threads 11 that form the fire-spinning fluff 7, the density of the fire-spinning fluff 7 can be increased or decreased, making it possible to easily adjust the firing time, making it possible to manufacture cores suitable for various appliances. There are also advantages that can be achieved.

Since the reinforcing core 4 is interposed between the first set of wefts 2 and the second set of wefts 3 which are repeatedly folded, the shape is maintained even during long-term use, and smooth combustion can be achieved for a long period of time. be.

The fluff-like part 7 for firing, which is formed by protruding from the folded upper end 9 of the first set weft 2 which is repeatedly folded and arranged, is a fine yarn bundled together with the many threads 1, 1, . . . which formed the first set weft 2. 11, 11, . . . , the fuel can be easily sucked up during the ignition operation, and ignition can be ensured.

Since two sets of heat-resistant combustion cores 15 can be knitted simultaneously and evenly on a warp knitting machine, uniform products can be efficiently produced.
