Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a wick for combustion appliances such as oil stoves and oil stoves, which allows the wick to move up and down smoothly.

If a conventional wick type combustion appliance is equipped with an anti-seismic automatic fire extinguishing device, if a vibration above a certain level is detected, the combustion wick will be rapidly lowered by a spring biased in the downward direction to extinguish the fire. However, since the combustion wick does not bend and extend smoothly, it does not go all the way down and stops midway, which prevents the fire from extinguishing and can lead to unexpected disasters.
Problems such as damage to the lifting mechanism such as the rack and pinion were also common.

The present invention was developed with focus on this point.
Examples will be described below with reference to the drawings. Reference numeral 1 denotes a core body, in which a heat-resistant combustion part 2 and a fuel suction part are vertically connected 4 by means such as sewing, and a reinforcing tape 5 is affixed to the connecting part 4 as well. Reference numeral 6 is a lead holder that fixes a rack plate 7 with an inclined rack 8 carved thereon, and although not shown, a core body 1 is interposed between the core inner cylinder and the core outer cylinder so that it can be raised and lowered, and a pinion 9 at the tip of the core adjustment knob is attached. The rack 8 is driven by the rotation of a pinion 9 which is engaged with the rack 8 and is interlocked with the rotation of the core adjustment knob, so that the core 1 is raised and lowered in a spiral manner between the inside of the core and the outer cylinder. It is a familiar thing.

It should be noted that some devices have been proposed in which a rack plate is attached vertically to allow the core to rise and fall vertically, but the lifting and lowering operations are difficult, especially for those with a large core diameter, making it difficult to raise and lower the core vertically. Since the wick is not raised and lowered unevenly at the front and rear, the wick exposure is not constant and combustion becomes uneven, so it is preferable to raise and lower the wick in a spiral manner in order to eliminate the above drawbacks. .

However, when the core body 1 is moved up and down in a spiral, if the fuel suction part 3 is made of warp and weft yarns, in order to make the bending part smooth, the warp in the bending part is eliminated and the combustion is formed only by the weft. A core has also been proposed, but it has the disadvantage of being complicated and costly to manufacture, so the applicant first aligns the long fibers a in one direction and then applies a short fiber random web layer b to this by needle punching, stitch bonding, etc. (Utility Application No. 56-183973), the core of the fuel wicking part is made of a non-woven fabric A that is integrated so that it does not peel off. As the lower back gets stronger and bending and stretching becomes uneven when the core is raised and lowered, a large number of cuts 10, 10, etc., which are inclined in the same direction as the helical direction in which the core body 1 moves up and down, are arranged in the bending part as shown in the figure. It was established.

In the present application, since a large number of cuts 10, 10 are arranged in parallel in the same direction as the helical direction as described above, when bending and stretching, the core body 1 is always bent and stretched in accordance with the helical direction, so that the core body 1 can be raised and lowered extremely smoothly. , especially when it comes to anti-earthquake automatic fire extinguishing.
This prevents excessive loads from being placed on the rack 8, pinion 9, etc.

That is, if the core body with the cuts vertically arranged side by side is simply lowered in a spiral direction, the core body may become twisted or tangled, making it impossible to move up and down, causing various troubles.

In addition, since the long fibers a improve the wicking of fuel through capillary action, the long fibers a are arranged in advance so that the direction of arrangement of the long fibers a is almost parallel to the inclined cuts 10, as shown in FIG. If you cut it, the corresponding cut 1
This can prevent fuel suction from being cut off due to zero.

The fuel wicking core 3 can be laminated in various ways, and as shown in Figure 4A, a single layer of long fibers a may be layered in the center layer and short fiber random web layers b may be layered on both sides. As shown in FIG. 4B, the long fiber layer a and the short fiber random web layer b can each be formed into a plurality of layers and laminated alternately so that the short fiber random web layer b becomes the outermost layer.
