Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a wick for combustion appliances such as kerosene stoves and kerosene stoves with significantly improved ignition performance.

Conventional technology There are two ways to ignite a wick for a combustion appliance: one is to bring a red-hot ignition heater close to the wick and ignite it, and the other is to ignite it by bringing a red-hot ignition heater introduced into the wick itself. In the latter method, both ends of the flat core material,
An annular core formed by connecting an ignition heater with the heat generating part upward and a spacing plate located at the bottom of the ignition heater in a ring shape by a connecting part IA (Japanese Patent Publication No. 52-22453)
(See Japanese Patent Publication No. 54-2101Q).

A coated electric heating resistance wire is installed inside the wick above the oil level in the tank, another electric heating resistance wire is installed permanently in the initial combustion or pyrolysis zone, and each electric heating resistance wire is connected to a separate transformer. (see Utility Model Publication No. 42-21424).

A core in which the -L end of the core is folded back in the inner circumferential direction, and a heating wire is built in the space between this folded piece and the core body over the inner periphery of the metal at the upper end of the core (see Japanese Utility Model Publication No. 45-310).

One or two cutouts are provided on the upper edge of the core, and a portion of the heating wire is exposed through the cutouts (
(See Utility Model Publication No. 47-10603 and Utility Model Publication No. 45-310).

A notch is formed on the rim of the core made of non-combustible fibers, and the ignition heater, which has both ends of the filament joined to the end of the power supply line connected to the notch, is connected inside the notch by sewing and sealing it inside the core. (see Utility Model Application Publication No. 61-69665).

etc. are known.

<Problems to be Solved by the Invention> By the way, in the above-mentioned prior art, the former means does not cause the fluff of the wick to come into contact with the filament of the ignition heater, causing the filament l to be cut, or to cause heat to be taken away by the fluff and become red-hot. There were some problems, such as difficulty. In addition, as a means of the latter,
-22453 and Japanese Patent Publication No. 54-21010 are as follows: 1. The fluff on both sides of the core material, which corresponds to the α-input area, may be deformed due to contact with the operator's hands or the combustion appliance when the wick is assembled into the combustion appliance, and due to combustion heat, especially high temperatures during dry firing. Heat deformation of the glass fibers in the fluff, volume deformation due to burning of flammable components such as rayon cloth or flame-resistant fibers, and shrinkage deformation due to tar formation due to long-term combustion or bad kerosene combustion, etc. Since the distance to the heat generating part changes, there is a problem that the ignition performance becomes extremely unstable.
The method disclosed in Publication No. 2-21424 heats and evaporates the fuel contained in the wick using a coated electric heating resistance wire provided inside the wick, and then heats and ignites the vapor in another electric heating resistance wire in the initial combustion zone. Therefore, the required power is naturally large, and there is a problem in that a normal 100 volt AC power supply must be used and a wiring cord is required.

In addition, the fuel is heated and evaporated by a coated electric heating resistance wire, and before it is heated and ignited by another electric heating resistance wire in the initial combustion zone,
There is also the problem that it takes time. (The normally required ignition time is about 1 to 3 seconds.) During this time, there is a major drawback in that white smoke and unpleasant odors are generated due to fuel vapor. Furthermore, since the device disclosed in Japanese Utility Model Publication No. 45-310 has a built-in heating wire, it takes a long time for the generated fuel vapor to reach the ignition point. During this time, there are major disadvantages in that white smoke and unpleasant odors are generated by the fuel vapor, and since it takes a long time, it is necessary to rely on a 100-volt AC power source other than dry batteries, and the combustion equipment requires a wiring cord, making it portable. It is inconvenient. Furthermore, the method disclosed in Publication of Utility Model Publication No. 47-10603 has problems such as it takes a considerable amount of time to ignite even if it is provided with a notch, and white smoke and odor are generated. The device disclosed in Publication No. 30268 requires a large amount of power because heating wires are arranged all around the wick, and since it cannot be ignited with dry batteries, it requires a wiring cord and is inconvenient to carry. Further, with this configuration, it is difficult to fix the heating wire in a predetermined position, and it is impractical. Furthermore, Utsukai Showa 61-69665
In the method disclosed in the above publication, the notch part of the nonflammable fiber core is easily deformed, so the distance between the ignition filament and the inner wall of the notch, which is the ignition part, is unstable, and there is no certainty as compared to the predecessor. . In addition, since the noncombustible fiber core is fluffed, the ignition filament and the fluff come into contact with each other, causing heat loss from the ignition filament, making it less likely to become red hot.

Furthermore, since the upper part of the notch is open, it is difficult to protect the ignition heater and there is a problem that the wire is easily broken.

That is, in the case of ignition by incorporating an ignition heater into the wick itself, the distance between the heat generating part of the ignition heater and the fluff changes due to deformation of the fluff at the ignition site, 1 and the direct flame performance becomes extremely unstable.

It takes time for the heater to ignite after being energized.

During this time, significant white smoke and unpleasant odor are generated due to fuel vapor.

The ignition filament is easily broken.

Because the amount of electricity required to heat the heater is large, it is not possible to use a small power source such as a dry cell battery, and since a 100-volt AC power source is used, a wiring cord is required, making it inconvenient to carry the combustion appliance. (It can only be used where there is a power source.)

The present invention solves the above-mentioned problems, and aims to provide a wick for a combustion appliance that significantly improves ignition performance and is convenient to use.

<Means for Solving the Problems> In order to achieve the above two objects, the wick for a combustion appliance of the present invention is made of only a heat-resistant hard plate-like body 2 made of porous ceramics and having fuel permeability; A heat-resistant hard plate-like body 2 is interposed between a core material main plate 7 made of glass fiber, flame-resistant fiber, ceramic It & navy blue-based woven or knitted fabric, etc. to form a heat-resistant core 3.
and a heat-resistant hard plate-like body 2 having a heat-resistant core 3 formed therein.
An ignition window 4 is bored at a position slightly below the upper end I&14, and an ignition metal filament 5 is provided in the ignition window 4, and the ignition metal filament 5 has a small gap 15 with the inner peripheral edge 6 of the ignition window 4. In addition, a notch recess 18 is formed by cutting out from the -L edge 1 of the heat-resistant hard plate-like body 2 on which the heat-resistant core 3 is formed, and a notch recess 18 is provided in the notch recess 18 located slightly below the upper edge 14. An ignition window 4 is bored in the ignition window 4, an ignition metal filament 5 is provided in the ignition window 4, a mounting body 8 made of the same material as the heat-resistant hard plate body 2 is removably attached, and the ignition metal filament 5 is provided in the ignition window 4. 5 is the inner peripheral edge 6 of the ignition window 4 and the booth 1
11=75 are provided and placed oppositely.

<Example> The present invention will be described in detail with reference to the drawings below. Reference numeral 2 denotes a heat-resistant hard plate-like body made of porous ceramics and having fuel permeability. An ignition window 4 is formed at a position slightly below the double edge 14 of the heat-resistant core 3, and an ignition metal filament 5 is provided in the ignition window 4. The heat-resistant core 3 of the embodiment shown in FIG. It is formed by being interposed between the core material main plates 7 made of textiles, knitted fabrics, etc. mainly made of fibers, and in the embodiment shown in FIG. A cutout recess 18 is formed by cutting out the upper edge 1, and the cutout recess 18
An ignition window 4 is formed at a position slightly below the upper edge 14, and an ignition metal filament 5 is provided in the ignition window 4,
A VC attachment body 8 made of the same material as the heat-resistant hard plate body 2 is detachably attached, and the ignition metal filament 5 is placed opposite the inner circumference i6 of the ignition window 4 with a small gap 15. Yes, and the mounting body 8 is attached to the notch recess 18.
8 and the mounting body 8 have guide grooves 19 and 19 on both sides and the guide groove 1.
9.19 is provided, and an insertion piece 13.13 is provided which is connected to the ignition filament 5 and projects from below the mounting body 8. is connected to the terminal 12.12, and is inserted into the insertion piece receiving hole 20.20 provided in the heat-resistant hard plate-like body 2, and the attachment body 8 is attached to the notch recess 18. 6 and 9 are fuel suction holes. It is a fuel wicking core made of cotton fiber etc. with good properties, and has many cutting strips 1.
0.10... is provided so that bending and stretching can be easily performed when the core is raised and lowered. Further, 11 is an upper and lower connection portion.

Further, the connection between the heat-resistant hard plate-like body 2 and the core material main plate 7 is performed through a connecting tool 16 such as a metal fitting, an adhesive tape, or an adhesive.

The inner peripheral edge 6 of the ignition window 4 facing the ignition metal filament 5 is smooth and free of fuzz, and the ignition window 4 is located at a position where at least a portion of the ignition window 4 is exposed from the fire pan during ignition operation. provided.

The metal filament 5 for ignition must be attached to the ignition window 4 so that it is exposed from the fire pan at least during the ignition operation, but it may be housed within the fire pan after ignition.

The ignition metal filament 5 may be in the form of an Ik edge wire or a coil, but is preferably in the form of a fill because it is more likely to become red hot.

As the material of the metal filament 5, oxidation-resistant materials such as platinum wire, nichrome wire, and stainless steel wire are used, but platinum wire, which has an oxidation catalytic action and causes the filament to become red-hot due to self-heating, is most preferable.

It is installed opposite to the metal filament 5 for ignition. The small gap 15 between the inner peripheral edge 6 of the α large window 4 is 0.3 to 5 mm, preferably 1 to 3 mm.
■ is better. If this distance is too slow, too much fuel vapor will be generated, and the mixing ratio of fuel vapor to air will be too high, making it difficult to ignite; if this distance is too slow, there will be too little fuel vapor, making it difficult to ignite.

The power supply at the time of ignition of the metal filament for ignition 5-1 is carried out either by using a dry battery (not shown) as a power source and directly connecting it to the terminal 12 of the metal filament for ignition 5 through a thin conductive wire 21, or by using a metal for ignition. There is a configuration in which power is supplied by bringing a power terminal (not shown) into contact with the terminal 12 of the filament 5 at the time of ignition.

Function> The wick for a combustion appliance configured as described above has an inner peripheral edge 6 opposite to the ignition metal filament 5 provided in the 7α fire window 4.
is composed of a heat-resistant hard plate-like body 2 that is permeable to fuel, so when the ignition metal filament 5 becomes red-hot, the opposing inner circumferential edge 6 is heated, and the fuel evaporates, instantaneously. Ignition takes place. The ignited fire is the upper edge 1 of the heat-resistant wick 3
It spreads around the entire circumference of 4, and the fire operation ends.

<Effects of the Invention> The present invention has the above configuration, and the inner peripheral edge 6 of the ignition window 4 facing the ignition metal filament 5 is a heat-resistant hard plate-like body 2 made of porous ceramics. Because it is smooth and has no fluff, it can be removed by accurately setting the distance from the ignition metal filament 5, and the heat-resistant hard plate-like body 2 has fuel permeability, so it contains a suitable amount of fuel and the ignition metal filament 5. 5, the fuel quickly evaporates from its surface and is easily and quickly ignited.

Furthermore, the distance between the ignition metal filament 5 and the opposing inner circumferential edge 6 does not change even after long-term combustion, and stable and reliable ignition can always be achieved. Further, the fuel supply to the heat-resistant hard plate-shaped body 2 in the ignition window 4-L section is insufficient to maintain normal combustion due to the presence of the flame-resistance window 4, and the fuel is always in an empty firing state. As a result, even when a fuel containing bad components such as bad kerosene is used for combustion, tar adhesion to this part is difficult and less, and ignition is carried out stably and reliably. In addition, it uses less electricity and can be ignited quickly, so it consumes less electricity, and the dry batteries can be used for a long time without having to be replaced, and since it does not require a 100-volt AC power source, it does not require a wiring cord, making it convenient to carry. . In addition, since the metal filament 5 for ignition is housed within the two direct fire windows 4 of the heat-resistant hard plate-like body 2, it is unlikely to come into contact with other obstructions, and damage such as wire breakage and deformation will not occur. Hard to occur. In addition, since ignition occurs quickly, fuel vapor is not dissipated into the surrounding area, and no white smoke or odor is generated during ignition. Furthermore, unlike the conventional ignition method where the burner is tilted during ignition and ignited through the open gap between the burner and the fire pan, it is possible to achieve so-called static ignition where the burner is ignited without tilting it, so no soot is generated during ignition.

Furthermore, since the heat-resistant hard plate-like body 2 having fuel permeability is made of porous ceramic material 12, it is robust and does not wear out, and the shape of the ignition window 4 does not change over a long period of time.
The interval between the two is maintained constant, and 2α fire can be reliably performed for a long period of time.

Also, a part of the edge 1 of the heat-resistant hard plate-like body 2 forming the heat-resistant core 3
A notched recess] 8 is formed, an ignition window 4 is bored in the notch recess 18 at a position slightly below the edge 14, and an ignition metal filament 5 is provided in the ignition window 4, An attached body 8 made of the same material as the heat-resistant hard plate-like body 2
is detachably attached, and the ignition metal filament 5 is disposed opposite to the inner peripheral edge 6 of the ignition window 4 with a small gap 15,
Even if the ignition metal filament 5 is broken due to a fire or the like, it is only necessary to replace the mounting body 8 with a new one, so parts costs are low and the work can be easily done even by an amateur.
