Description

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

<<Prior art>> As shown in FIG. 3, there is no known conventional wick for combustion appliances in which a non-combustible wick 34 is provided at the upper part and a cotton wick 35 is provided at the lower part, and a stapler is used as a means for joining the two. (Refer to Utility Model Publication No. 55-42087).

Further, as shown in FIGS. 4 and 5, thick warp threads 30 made by simply bundling or twisting glass, cotton, or other fibers are arranged horizontally to form a warp layer 31, and glass fibers are coated on both the front and back sides of the warp layer 31. Felt fiber layer 3
A wick for a combustion appliance is known in which the glass fibers of the felt fiber layers 32, 32 are polymerized and entwined with the thick warp threads 30 arranged horizontally by needle punching (see Japanese Patent Publication No. 49-36170). ).

Further, as shown in FIGS. 6 and 7, a fuel suction part 38 is formed by aligning a large number of long fibers 36 in parallel in the vertical direction, providing short fiber random webs 37, 37 on the outer surface, and integrating them with a needle punch. It is known that a heat-resistant combustion part 39 is connected to the upper part of the wick to serve as a wick for a combustion appliance (see Japanese Utility Model Application Publication No. 88510/1988).

<<Problems to be Solved by the Invention>> By the way, when the device shown in FIG. 3 is attached to an instrument and used, the joint portion using a stapler may damage the lead guide cylinder surface due to repeated up and down operations of the lead. The occurrence of rust damages the equipment, and it is also impossible to evenly absorb oil from the cotton wick 35 to the non-combustible wick 34 over the entire surface. There were drawbacks such as inability to burn smoothly.

In addition, in the wick for a combustion appliance shown in FIGS. 4 and 5, the glass fiber felt-like fiber layers 32, 32 are made by simply gathering or twisting glass, cotton, or other fibers on the entire surface with thick warp threads 30 horizontally. In parallel, the warp layer 31
The glass fibers of the felt-like fiber layers 32, 32 are entwined with the horizontally parallel thick warp threads 30 by needle punching, so that the adjacent thick warp threads 30 are separated and many separated voids are formed. Thick warp threads 30 in which thick warp threads 33, 33... are formed and are arranged in parallel.
The warp layer 31 and the felt-like glass fiber layers 32 and 32 come into contact with each other and come apart, and furthermore, the warp 30 is deformed and the dimensions are unstable when the device is attached, resulting in poor fuel suction. The flames are not evenly distributed and the flames are not evenly aligned, and the warp layer 31 formed with thick warp threads 30 causes the warp threads 30 to become uneven when the core is raised and lowered. There were drawbacks such as the inability to do so. That is, what is shown in Figures 4 and 5 is
The large-diameter warp threads 30 are made by simply bundling glass fibers or the like in one direction, or by twisting these bundles to form the large-diameter warp threads 30, so that when the needle is inserted by needle punching, the needle tip does not When hitting and piercing a large-diameter warp thread 30, a strong force acts to pierce the needle tip into the warp thread 30, causing problems such as separating the warp threads 30 and the felt-like fiber layer 32, and when inserting a needle with a needle punch. When the tip pierces between adjacent large diameter warps 30, 30, a force acts to separate the large diameter warps 30, 30, and the warp layer 31 formed by arranging the large diameter warps 30 is formed by needle punching. The thickness of the warp layer 31 differs depending on the insertion point of the warp layer 31 and the felt fiber layer 3.
2 and 32 are different in the degree of entanglement.

In addition, since the warp layer 31 is formed by arranging a large number of warps 30 with a large diameter, the thickness is not uniform over the entire surface, but the suction of oil through the warps 30 with a large diameter is uniform on average. Furthermore, it is impossible to uniformly supply oil to the felt fiber layers 32, 32 through the warp threads 30 over the entire surface, which results in uneven fuel suction and uneven supply. It had drawbacks such as the inability to carry out combustion.

In addition, in the case shown in FIGS. 6 and 7, the heat-resistant combustion section 39 is not provided with fibers corresponding to the large number of long fibers 36 provided in the fuel suction section 38, so that oil does not reach the tip of the heat-resistant combustion section 39. In addition, during repeated wick up and down operations, the fuel suction part 38 and the heat-resistant combustion part 39 may become damaged due to cutting or loosening of the thread at the joint. When separated, the suction of fuel becomes insulated and does not reach the heat-resistant combustion section, resulting in poor combustion.

This invention solves the above-mentioned problems, and allows fuel to be sucked up efficiently, evenly, and without uneven combustion, and it is possible to supply a wick with a desired thickness depending on the model. It is easy to do, and the heating power can be adjusted smoothly by raising and lowering the wick to prevent uneven combustion. Nonwoven interlining can be mass-produced at low cost. To obtain a wick for a combustion appliance that is convenient to use, such as being able to take a large height (distance), preventing liquid fuel from being heated to a high temperature, and continuing safe combustion. The purpose is to

<<Operations and Effects of the Invention>> According to the present invention, the following operations and effects can be obtained.

Since the heat-resistant short fiber random web layers 2, 2 and the non-heat-resistant short fiber random web layers 4, 4 are formed from non-woven fabric, fraying does not occur at the cutting edges, and it is possible to cut by punching etc., making it possible to cut to size. Can be manufactured uniformly without variation.

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 upper heat-resistant long fiber layer 1 of the heat-resistant fiber layer section 3 and the lower long fiber layer 9 of the fuel wicking fiber layer section 5 can achieve the same effect as if a large number of capillary tubes were passed through in the length direction as well as achieve a high fuel wicking speed. By having this, it is possible to generate a high calorific value, and it is also possible to increase the height between the liquid level of the liquid fuel in the fuel tank and the combustion part, so that the liquid fuel in the fuel tank is This avoids the risk of being heated to high temperatures.

Polymerized and formed integrally by needle punching, it becomes strong, and as shown in Figure 4,
Unlike the conventional wick for combustion appliances shown in FIG. 5, dimensional variations such as non-uniform thickness do not occur, and troubles due to dimensional changes during use can be eliminated.

In combustion appliances with a fuel tank located at the bottom, even if the fuel level in the fuel tank decreases as the combustion time increases, the suction of fuel does not decrease, so the firepower does not weaken.
