Abstract

PURPOSE:To facilitate a use through sharp improvement of ignition performance by a method wherein a wick material sheet formed by flame resistant fibers is impregnated with an initial condensate of thermosetting resin to thermoset it, and an ignition window is formed in a heat resistant wick and positioned facing a metallic filament for ignition. CONSTITUTION:A wick material sheet 1 consisting mainly of flame resistant fibers is impregnated with an initial condensate of thermosetting resin to thermoset it. A heat resistant wick 3 is formed by a heat resistant rigid plateform substance 2 having fuel permeability. An ignition window 4 is formed in a position slightly below an upper edge 14 of the heat resistant wick 3, and a metallic filament 5 for ignition is provided in the ignition window 4. The metallic filament 5 for ignition is positioned facing an inner peripheral edge 6 with a small gap 15 therebetween. Since the inner peripheral edge 6 is formed by a heat resistant thermosetting plateform substance 2, fuel is vaporized, and a momentarily ignited flame is spread throughout the whole periphery of the upper edge 14 of the heat resistant wick 3. A distance from the inner peripheral edge 6 positioned facing the metallic filament 5 for ignition is not changed even when combustion is effected for a long period, and normally stable reliable ignition is executed.

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.

<Prior art> 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 making an ignition heater built into the wick itself red-hot. , and as a means of the latter name, both ends of the flat core material,
An annular core formed by connecting an ignition heater with the heat generating part upward and a spacer plate located at the lower part of the ignition heater in an annular manner by a connecting member (Japanese Patent Publication No. 52-22453, Japanese Patent Publication No. 54-1988) (See Publication No. 21010).

A coated electric heating resistance wire is installed in a part of 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 installed separately. A core connected to a transformer (see Utility Model Publication No. 42-21424).

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

One or two notches of -L are provided on the upper edge of the core so that a part of the heating wire is exposed from these notches. reference).

A notch is formed on the upper edge of a noncombustible fiber core, and an ignition heater is fixed inside the notch, with both ends of the filament joined to the end of a power supply line that is sewn and sealed inside the core and conductive to the notch. (Refer to Utility Model Publication No. 61-69665).

etc. are known.

<Problems to be Solved by the Invention> By the way, in the conventional technique described above, the former means causes the fluff of the lamp wick to come into contact with the filament of the ignition heater, causing the filament to be cut, or the fluff to absorb heat and cause it to become red-hot. There were some problems, such as difficulty. In addition, as a means of the latter,
In the Mononoke disclosed in Japanese Patent Publication No. 54-21010 and Japanese Patent Publication No. 54-21010, the fuzz portions on both sides of the core material corresponding to the 7 ignition parts are exposed to the hands of the operator when the core is assembled into the combustor. Deformation due to contact with combustion appliances, thermal deformation of the glass fibers in the fluff due to the heat of combustion, especially the high temperature during dry firing, volume deformation due to burning off of combustible components such as rayon cloth or flame-resistant WL navy blue, and even long-term deformation. Due to the formation of tar due to combustion, poor kerosene combustion, etc., the distance between the ignition heater and the heat generating part changes due to shrinkage and deformation, resulting in a problem that the ignition performance becomes difficult and unstable.
The fuel contained in the wick is heated and evaporated by a coated electric heating resistance wire installed inside the wick, and the vapor is heated and ignited by 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 wiring cord is required which necessitates the use of a normal 100 volt AC power source. Another problem is that it takes some time for the fuel to be heated and evaporated by the coated electric heating resistance wire and then heated and ignited by another electric heating resistance wire in the initial combustion zone. (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 considerable amount of time for the generated fuel vapor to reach the ignition point. During this time, there is a big disadvantage that white smoke and unpleasant odor are generated due to fuel vapor, and it takes a long time, so it is difficult to use batteries other than dry batteries.
It has no choice but to rely on a volt AC power source, etc., and a wiring cord is required for both the combustor, making it inconvenient to carry. Furthermore, the method disclosed in Utility Model Publication No. 47-10603 has problems such as requiring a considerable amount of time to ignite even if it is provided with a cutout, and generating white smoke and odor. The device disclosed in Japanese Patent No. 47-30268 requires a large amount of electric 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, in 1986. The one disclosed in Publication No. 69665 is that the notch part of the non-combustible N & miscellaneous core is easily deformed.
The distance between the ignition filament and the inner wall of the notch that serves as the ignition site is stable, and there is no certainty of ignition.6 Also, since the nonflammable fiber core has a fluffy part, the ignition filament and the fluff will not come into contact with each other. Heat is lost from the ignition filament, making it less likely to become red hot.

Furthermore, the top of the notch is open, so the ignition heater can be kept in place! The problem is that it is difficult to connect and easily breaks.

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 the deformation of the fluff at the ignition site, and the ignition performance becomes Ml,<
Becomes unstable.

It takes quite a while for the heater to ignite after being energized.

When this happens, obvious 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.)

This invention solves the above-mentioned problems, and aims to provide a combustor common wick that significantly improves ignition performance and is convenient to use.

Means for Solving the Problems> In order to achieve the above object, the wick for a combustion appliance of the present invention has the following features:
Glass vapor, ceramic vapor, glass fiber/flame resistant m
A core material plate 1 made of felt mainly made of fibers/ceramic fibers, woven fabrics/knitted fabrics mainly made of glass fibers, flame-resistant fibers, ceramic fibers, etc. is impregnated with an initial condensate of a thermosetting resin and then thermoset]7 Fuel Heat-resistant hard plate-like body with permeability 2
Alternatively, a heat-resistant hard plate-like body 2 is interposed between core material main plates 7 made of woven fabrics, knitted fabrics, etc. mainly made of glass fibers, flame-resistant fibers, and ceramic fibers to form a heat-resistant core 3. An ignition window 4 is provided at a position slightly below the upper lIi edge 14 of the heat-resistant hard plate-like body 2 formed with the ignition window A, and an ignition metal filament 5 is provided in the ignition window A. is arranged opposite to the inner peripheral edge 6 of the ignition window 4 with a small gap 15, or the ignition window 4 is equipped with a ceramic sintered body 8 provided with a metal filament 5 for ignition, and the metal filament 5 for ignition is It is arranged opposite to the inner circumference J1iH6 of the ignition window 4 with a small opening [15].

<Example> The present invention will be described in detail with reference to the drawings below. 1 is a core material plate, which includes glass vapor, ceramic vapor, felt mainly composed of glass fiber/flame-resistant fiber/ceramic fiber, glass fiber/flame-resistant fiber/ceramic fiber. This core material plate 1 is impregnated with an initial condensation product of a thermosetting resin, and a heat-resistant hard plate-like body 2 that is heat-cured and has fuel permeability is used to form a heat-resistant core 3. formed and heat-resistant core 3
An ignition window 4 is bored at a position slightly below the upper edge 14, and an ignition metal filament 5 is provided in the fire window 4,
The α-use metal filament 5 is arranged opposite to the inner peripheral edge 6 of the ignition window 4 with a small gap 15, and the heat-resistant core 3 of the embodiment shown in FIG. Body 2, glass WLIA! It is formed by being interposed between the main plates 7 of the core material, which is made of a woven fabric or knitted fabric mainly made of flame-resistant fibers, ceramic fibers, etc. In the embodiment shown in FIGS. 4 and 5, the ignition window 4 is A ceramic sintered body 8 provided with a metal filament 5 for ignition is mounted, and the metal filament 5 for ignition is attached.
This is a small gap 15 formed by cutting the inner peripheral edge 6 of the 7-sided fire window 4. Further, 9 is a fuel wicking core made of cotton fiber or the like having good fuel wicking properties, and has a large number of cut strips 10.10.
... 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.

In addition, the properties of the thermoset heat-resistant rigid plate-like body 2 do not easily deform even when external forces such as bending are applied, and when one end is immersed in fuel such as kerosene, the fuel is drawn up to the top due to capillary action. However, if press pressure is applied during thermoforming to compress the heat-resistant hard plate-like body 2 and increase its density, the fuel wicking performance can be further improved.

In addition, the inner circumference M6, which is the cutting edge of the ignition window 4 formed with a punching blade, etc.
It is smooth and has no fluff.

Furthermore, during thermosetting, it is preferable to form the material into an arcuate shape in accordance with the shape of the gap between the inner core cylinder and the outer core cylinder of the combustor box.

It is also formed into a flat plate shape, and on one surface thereof, a large number of slits 13 are provided at intervals of several tow and the depth is 1/3 to 1/2, and the slits 13 It can also be deformed by folding at the .13... part to form an arc shape.

As the thermosetting resin, phenol resin, melamine resin, urea resin, epoxy resin, etc. can be used, but phenol resin is most preferred.

In addition, the connection between the heat-resistant hard plate-like body 2 and the core material main plate 7 is performed by suture.
Connections such as fitting and adhesion to the metal fittings I are made through the metal fittings 16.

Inner periphery M of the ignition window 4 opposite to the ignition metal filament 5
The ignition window 6 is smooth and free of fuzz, and the ignition window 4 is provided at a position where at least a part of the ignition window 4 is exposed from the fire pan during ignition operation. Further, the ignition window 4 can be provided by cutting it out using a punching blade such as a punch.

The ignition metal filament 5 must be installed in 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 either linear or coiled, but a coiled filament is preferred because it is more likely to become red hot.

The metal filament 5 may be made of a material that is oxidation resistant, such as platinum wire, nichrome wire, or stainless steel wire, but platinum wire is most preferable because it has an oxidation catalytic action and causes the filament to become red-hot due to self-heating.

The metal filament 5 for ignition is attached to the ceramic sintered body 8 and attached to the ignition window 4 because it requires a complicated process to attach it to the ignition window 4 of the heat-resistant hard plate body 2. It is preferable.

The ceramic sintered body 8 preferably has a structure in which the ignition metal filament 5 is stretched over a notch 21 in which a portion is cut out.

With this configuration, the ignition metal filament 5
The ignition window 4 can be easily opened several times without coming into contact with the inner peripheral edge 6 of the ignition window 4.

The small gap 15 between the inner peripheral edge 6 of the ignition window 4 facing the ignition metal filament 5 is 0.3 to 51o+n, preferably I-< is i
-3 tam is good. If this point is too close, too much fuel vapor will be generated and the 3174 ratio of fuel vapor to air will be too high, making it difficult to ignite; if it is too close, there will be too little fuel vapor, making it difficult to ignite.

The ceramic sintered body 8 can be attached to the ignition window 4 by means of adhesion, metal fittings, etc., but in the case shown in FIG.
The needle portions 20, 20, . . . are provided in a protruding manner, and the needle portions 20, 20, .

Power is supplied to the metal filament 5 for ignition during ignition by using a dry battery as a power source, and directly connecting it to the metal filament 5 for α using a thin conductor (not shown).1. Alternatively, there is a configuration in which power is supplied by bringing a power terminal (not shown) into contact with the terminal 12 of the ignition metal filament 5 provided on the ceramic sintered body 8 during the fire.

The part of the ignition window 4 made of the heat-resistant hard plate 2 that is exposed from the fire pan (not shown) during combustion is exposed during dry firing (to remove tar, the fuel in the wick is drained by cutting off the fuel). Since the temperature is around 800°C during the burning operation), thermosetting U (core material plate 1 made of glass vapor etc. after the fat is burned off) is used.
However, as a result of experiments, the deformation of the shape can be prevented by sewing this part with a plus fiber thread 18 or by impregnating it with a heat-resistant PIi-free adhesive 19. We were able to.

Function> In the combustor common wick configured as in -I-, the inner periphery A116 opposite to the metal filament 5 for the incoming fire provided in the ignition window 4 is made of a heat-resistant hard plate with fuel permeability. Since it is composed of a shaped body 2, when the ignition metal filament 5 becomes red hot, the opposing inner peripheral edge 6 is heated and the fuel evaporates.
Ignition occurs instantly. The ignited fire spreads all around the edge 14 of the heat-resistant wick 3, and the ignition operation is completed.

<Effects of the Invention> The present invention has the following configuration, and the inner peripheral edge 6 of the ignition window 4 facing the ignition metal filament 5 is mainly made of glass vapor, ceramic vapor, glass fiber/flame-resistant fiber/ceramic fiber. Made of felt, woven and knitted fabrics mainly made of glass fiber, flame-resistant fiber, and ceramic fiber,
This core material plate 1 is impregnated with an initial condensate of thermosetting resin,
Since it is formed by cutting the heat-resistant hard plate-like body 2 formed by thermosetting, it is smooth and free of fluff, and the distance to the ignition metal filament 5 can be set accurately. Since the body 2 has fuel permeability, it contains an appropriate amount of fuel, and the fuel is quickly evaporated from its surface by heating from the ignition metal filament 5, and the body 2 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, allowing stable and reliable α-fire to be performed at all times. Further, the fuel supply to the heat-resistant hard plate-like body 2 above the ignition window 4 is insufficient to maintain normal firing due to the presence of the ignition window 4, and the fuel is always in an empty firing state. As a result, even when fuel containing bad components such as defective kerosene is used for combustion, there is very little tar deposited on this part, and ignition is carried out stably and reliably.

In addition, it consumes little electricity and can be ignited quickly, so dry batteries can be used for long periods of time without having to be replaced, and there is no need for a 100 volt AC power supply, so there is no wiring cord, making it convenient to carry. be. Also, heat-resistant hard plate-shaped body 2
Since the ignition metal filament 5 is housed within the ignition window 4, it is unlikely to come into contact with other obstructive objects, and damage such as wire breakage or deformation is unlikely 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 in which the burner is tilted during ignition and the ignition heater is brought close to the wick through an unavoidable gap between the burner and the fire pan, stationary ignition can be achieved without tilting the burner, which eliminates soot during ignition. Occurrence [7 not present.

Furthermore, the heat-resistant hard plate-like body 2 forming the ignition window t is made of glass vapor, ceramic vapor, glass fiber, flame-resistant fiber, etc.
The core material plate 1 is impregnated with an initial condensate of a thermosetting resin, and is formed by thermosetting 17. Because of this, it is easy to cut with a knife and can be cut out with a punch-like punch, making it easy to process.The mounting position of the ignition window 4 can be appropriately selected to ensure ignition. This is something that can be done.
