Description

[Detailed Description of the Invention] << Industrial Application Field >> This invention is used for combustion equipment such as petroleum hobs and petroleum stoves that use kerosene as a liquid fuel and can perform good ignition over a long period of time. Regarding the core for equipment.

<< Prior Art >> Conventionally, as shown in FIG. 7 and FIG. 8, discharge ignition is performed using a gap formed between an ignition plug 21 and a wick 22 as an ignition device for a wick for a combustion appliance. In order to prevent the fibers from falling apart, at least a part of the fiber end of the wick is bound with the weft 23 and restrained, and the spark plug
It is known that a restraint portion 24 is provided at a position facing 21 (see Japanese Utility Model Laid-Open No. 58-58219).

Further, as shown in FIG. 9, in the core for a combustor, in order to improve the ignition performance, a heat-resistant combustion core 30 provided with a notch portion 31 at its tip is known (Actual No. Sho 64-1218). See the bulletin).

<Problems to be solved by the invention> By the way, as shown in FIGS. 7 and 8, a gap formed between the ignition plug 21 and the wick 22 is used as an ignition device for the wick of the combustion appliance. In the case of discharge ignition, there is a drawback that if tar accumulates in the discharge part of the core, the discharge is interrupted and the ignition performance deteriorates, making it impossible to ignite. At least a part of the fiber end of the upper edge is bound with a weft 23 and restrained, and the spark plug
The one that has the restraint portion 24 at the position facing 21 is one weft
The fiber end of the wick upper end 22 is bound by 23 and restrained, and since the restraint portion 24 is provided at a position facing the spark plug 21, the fiber end of the wick upper end 22 is bundled with one weft thread 23 and is too loose. The ignition unit is only able to prevent the unevenness due to
The fibers at the position facing 20 were scattered, and the fluffing of the fibers and the ignition plug 21 were in contact with each other, and the ignition filament of the ignition plug 21 was damaged, which made ignition impossible.

Further, as shown in FIG. 9, in order to improve the ignition performance, the heat-resistant combustion wick 30 provided with the notch 31 at the tip end thereof does not lose the shape of the wick when it is attached to the combustion instrument and is moved up and down. This is liable to occur, and therefore the exposed dimensions of the wick are varied to generate soot, carbon monoxide, etc., and abnormal combustion is likely to occur.

This invention solves the above problems, improves the ignition performance of the wick, and further accumulates tar in the ignition part when burning for a long time, which is a problem with conventional ignition performance, and the ignition performance is improved. To prevent the deterioration of the wick, and further to solve the drawbacks such as abnormal combustion due to the shape of the wick and the defective ignition due to the damage of the ignition filament of the ignition heater, and to obtain a wick for a combustion appliance that can withstand long-term use. It is intended for.

<< Means for Solving the Problems >> A core for a combustion instrument of the present invention for achieving the above object is a core provided with a heat-resistant combustion core 1 made of heat-resistant fiber, such as glass fiber, metal fiber, etc. The heat-resistant fiber yarn 2 formed by strongly twisting the heat-resistant fiber 1 is used, and the heat-resistant combustion core 1 is closely aligned in a vertical direction of the heat-resistant combustion core 1 on the side wall portion 3 of the heat-resistant combustion core 1 which is close to the ignition heater. A plurality of sewn thread yarns 4, 4 that are sewn and sewn are provided, and the surface of the heat-resistant combustion core 1 is covered with the plurality of sewn thread yarns 4, 4 that are closely arranged and sewn.

2 is made of heat resistant fiber such as glass fiber and metal fiber,
It is a heat-resistant fiber yarn that is strongly twisted to suppress oil absorption, and 3 is a core side wall portion that brings the ignition heater of the heat-resistant combustion core 1 close to it. The core side wall portion 3 is orthogonal to the vertical direction of the heat-resistant combustion core 1. Then, a plurality of sewing thread yarns 4,4 ... which are closely arranged and sewn using the heat-resistant fiber yarn 2 are provided, and a plurality of sewing thread yarns 4,4 ... which are closely arranged and sewn are provided. The heat-resistant combustion wick 1 is coated with an ignition surface portion 5 formed thereon.

The heat-resistant fiber yarn 2 has, for example, a glass fiber or a metal fiber (stainless fiber) having a fineness of 6 microns or less, preferably 5 microns or less, having a count of 68 to 135 tex and a twist number of about 500 to 350 times / m. The strongly twisted glass fiber thread or metal fiber thread (stainless fiber thread) is used. Since the twisted glass fiber yarn and metal fiber yarn have a remarkably low oil absorbency, the so-called air-fired state is sewn to the heat-resistant combustion core 1, so that tar is accumulated even after long-term combustion. Does not occur and has stable ignition performance. In addition, since the twisting is sufficient, the heat-resistant fiber thread 2 has a good bundling property, and the heat-resistant fiber thread 2 is lock stitched to form the sewing thread 4 with the heat-resistant fiber thread 2 (see FIG. 3A). Or chain stitch (Fig. 3B
