Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cylindrical core for combustion appliances such as oil stoves and oil stoves that use kerosene or the like as fuel.

<Prior art> This type of conventional cylinder core for combustion appliances has a heat-resistant wick made of glass fiber or a thick fabric made of a blend of glass fiber and carbon fiber on the upper part of the fuel suction part made of a thick fabric made of cotton yarn or a blend of cotton and rayon. The interlining to which the combustion part is connected is structured into a cylindrical core body, and when forming the fuel suction part, it is woven with warp and weft threads with a constant weaving width G on a loom as shown in Figure 7. A bent part 31 formed only by the woven fabric part 30 and warp threads
are continuously formed into a belt shape, and further a woven fabric portion 30 is formed.
Both ends 33, 33 of the cloth G through the cutting part 32
It is known that a cylindrical fuel suction part is formed by connecting the two. Further, as shown in FIG. 8, for example, a knitted fabric 35 and an extra length 36 to prevent fraying provided at a cut portion for forming a cylindrical core body are continuously provided by a knitting machine. It is known from Japanese Utility Model Application Publication No. 54-94637 or Japanese Patent Application Publication No. 56-124813.

<Problems to be Solved by the Invention> By the way, in the former cylindrical core for combustion appliances having such a configuration, the weaving width G is wide during weaving and the swinging width of the weft becomes long when forming the fuel suction part. The rotation speed of the loom is limited to approximately 60 to 120 times per minute, resulting in extremely low productivity and inefficiency, and the connection between the fuel suction section and the heat-resistant combustion section cannot be made continuously.
In addition, dimensional variations tend to occur, resulting in a high defective rate, and in addition, the core tends to shrink during use, causing problems such as sticking to the core guide tube of the instrument and failure to raise and lower the core. In other words, it is not possible to adjust the firepower by raising and lowering the wick, and the flame is not evenly aligned due to deformation of the wick or unstable dimensions when the device is attached, and the cloth G cannot be adjusted depending on the model. There were drawbacks such as the need to make changes. In addition, in the case of the latter, in which the continuous knitted fabric 35 is formed by a knitting machine, the outer diameter of the core guide tube differs depending on the type of combustion appliance, so the extra length parts 36, 36 are cut.
It is necessary to prepare many types of knitted fabrics 35 with different sizes, which has the disadvantage of often being in short supply.

This invention solves the above-mentioned problems, and provides a convenient combustion system that has good fuel suction efficiency, is easy to manufacture, can be mass-produced at low cost, and can smoothly move the wick up and down over a long period of time. The purpose is to obtain a cylindrical core for instruments.

<Means for Solving the Problems> To achieve the above object, the cylinder core for a combustion appliance of the present invention is woven with warp and weft yarns made of fibers having good fuel absorption properties such as cotton fibers. A fuel wicking core band 1 is formed, and the fuel wicking core band 1 is provided with an upper wide part 2 having warp threads, an intermediate wide bent part 3 without warp threads, and a bottom narrow part 4 having weft threads,
Further, the upper wide part 2 is provided with notches 5, 5... in the vertical direction at intervals, and the narrow hem part 4 is provided with notches 7, 7... at intervals, and a fuel suction core is provided. At the upper end of the band 1, a heat-resistant combustion core band 8 made of heat-resistant fiber such as glass fiber and having a constant width is connected to a horizontal connection part 9.
The strip-shaped core 10 is further cut according to the cylindrical core growth length L, both ends are connected via the vertical connection part 11, and a heat-resistant combustion wick 12 is attached to the upper part. A cylindrical core 14 is formed with a fuel suction core 13 provided at the lower part thereof.

<Example> An example of the present invention will be described below with reference to the drawings. 1 is a fuel wicking core band, which is woven with warp and weft yarns made of fibers with good fuel wicking properties such as cotton fibers, and is a fuel wicking core band. An upper core belt 1 is formed, and the fuel wicking core belt 1 is provided with an upper wide part 2 having warp threads, an intermediate wide bending part 3 without warp threads, and a bottom narrow part 4 having warp threads. The wide width part 2 is provided with notches 5, 5... in the vertical direction at intervals, and the narrow hem width part 4 is provided with notches 7, 7...
A heat-resistant combustion core band 8 made of heat-resistant fiber such as glass fiber and having a constant width is connected to the upper end of the fuel wicking core band 1 via a horizontal connection part 9 to form a band-shaped core 10. Furthermore, the belt-shaped core 10 is cut at a cylinder core shape growth length L formed according to the outer circumferential dimension of the core guide tube, which varies depending on the model, and both ends are connected via a vertical connection part 11, and a heat-resistant combustion wick 12 is attached to the upper part. A cylindrical core 14 is formed with a fuel suction core 13 provided at the bottom thereof.

Further, 6 is a fray-preventing sewn portion sewn above and below the notch strip 5, 18 is a first adhesive for fraying prevention applied to the periphery of the notch strip 5, and 15 is a fray-preventing adhesive applied to the periphery of the notch portion 7. This is the second adhesive.
In addition, as shown in FIG. 2, the fuel wicking core band 1 may be subjected to flameproofing 16 to give it heat resistance, or as shown in FIG. By applying a flame finish 16 and a water repellent finish 17 to the lower part, a heat-resistant and waterproof fuel wick 13 can be obtained. In addition, as shown in Fig. 6, the entire fuel wicking core band 1 is given a water repellent finish 17, and only the upper part is given a flame retardant finish 16.
It is also possible to apply

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

(1) Since the tube core shape growth L can be freely selected according to the outer circumferential dimension of the core guide tube (not shown), which differs depending on the model, the weaving width can be changed for each type as in the conventional product shown in Figure 7. Products of different sizes can be easily manufactured by simply changing the cutting dimension, that is, the cylindrical core growth length L, without changing G.

(2) In the fuel wicking core band 1, the intermediate wide bent portion 3 is formed only of weft yarns, and the upper wide portion 2 and the narrow hem portion 4 are knitted with the aforementioned weft yarns and warp yarns, as shown in Fig. 7. Since continuous weaving can be performed with a relatively shorter weave width B as shown in Figure 1 than the weave width G of the conventional example shown in the figure, the rotation speed of the loom is extremely high at approximately 800 rpm compared to the conventional approximately 60 to 120 revolutions/min. It can be woven at ~1600 times/min and can be manufactured efficiently.

(3) The upper wide part 2 of the fuel wicking wick band 1, which has a cylindrical wick 14 with a heat-resistant combustion wick 12 in the upper part and a fuel wicking wick 13 in the lower part, has an interval. Cut lines 5, 5... are provided in the vertical direction to impart elasticity, and cuts 7, 7... are also provided in the hem width portion 4, so that the fuel suction wick 13 contracts even during long-term use and guides the wick. Eliminates defects such as the inability to move the core up and down due to biting in the cylinder.

(4) Since the notches 5, 5... are not provided on the heat-resistant combustion wick 12, the shape of the heat-resistant combustion wick 12 formed in a cylindrical shape may collapse during long-term use, making it impossible to raise and lower the wick smoothly, and the wick may fall out of the fire pan. The exposure of the top end of the wick will not be uneven, and the flame will not be uneven.

(5) Since the heat-resistant combustion wick band 8 forming the heat-resistant combustion wick 12 and the fuel wick band 1 forming the fuel wick 13 are continuously connected via the lateral connection part 9, the desired cylindrical core shape growth can be achieved. Heat-resistant combustion wick 1 when cutting into L size
2. Both fuel suction wicks 13 can be manufactured without dimensional errors.

(6) Vertical notches 5 formed in the upper wide part 2 of the fuel wick 13 with good fuel wicking characteristics;
5... is a straight line, and the notch line 5 does not have a wide area space, so there is no problem in sucking up the fuel, and the fuel is sufficiently supplied to the heat-resistant fuel wick 12, thereby preventing a strong fire. You can gain power.

(7) The intermediate wide bending portion 3 bends smoothly when moving up and down the core, allowing for effortless adjustment of firepower.
