Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to a wick for a combustion appliance which has remarkably improved ignition performance of a petroleum stove, a cooking stove or the like.

[0002]

2. Description of the Related Art There are two types of methods for igniting a wick for a burning appliance, a means for igniting a red-heated ignition heater close to the wick and a means for igniting a red-heated ignition heater incorporated in the wick itself. And as the latter means, Japanese Patent Publication No. 52
As disclosed in Japanese Patent Publication No. 224453, an ignition heater having a heat generating portion on both sides of a flat plate-shaped core member;
There is known an annular core formed by being annularly connected by a connecting member via a spacing plate located below the ignition heater.

Further, as disclosed in Japanese Utility Model Publication No. 45-310, the upper end of the core is folded back in the inner circumferential direction, and a heating wire is provided in the space between the bent piece and the core body over the entire inner circumference of the upper end of the core. The built-in core is known.

Further, as disclosed in Japanese Utility Model Publication No. 47-10603, one or more notches are provided in the upper edge of the core, and a part of the heating wire is exposed from the notches. Things are known.

As shown in FIGS. 4 and 5, a notch 31 is formed on the upper edge of the non-combustible fiber core 30, and the feeder lines 32 and 32 are sewn inside the core and electrically connected to the notch 31. It is known that the ignition heater 33, in which both ends of the filament are joined to the end of the above, is fixed in the cutout portion 31 (Actual development Sho 6).
1-69665).

In a burner having a kerosene suction core 35 as shown in FIGS. 6 and 7, a through hole 37 penetrating the lamp core is provided in the lower part of the upper end vaporization surface 36, and the through hole 37 is ignited. It is known that the heater 38 is inserted (see Japanese Utility Model Laid-Open No. 54-173345).

[0007]

However, the former means in the above-mentioned conventional technique is that the fluff of the wick comes into contact with the filament of the ignition heater and the filament is cut, or the fluff absorbs heat to cause red heat. There were problems such as difficulty. Further, as the latter means, the one disclosed in Japanese Patent Publication No. 52-22453 discloses that the fluff portions at both ends of the core material corresponding to the ignition part are used by the operator's hand or the combustion at the time of assembling the core into the combustion instrument. It deforms due to contact with equipment, and due to high temperature such as empty heating, it causes thermal deformation of the fluff part and further contraction deformation due to tar formation due to long-term combustion, bad kerosene combustion, etc. There is a problem in that the ignition performance becomes significantly unstable because the distance between the wick and the igniting part of the wick changes and the heat generating part of the ignition heater and the igniting part of the wick are separated from each other.

Further, in the one disclosed in Japanese Utility Model Publication No. 45-310, since the heating wire is built in the core, it takes a considerable time for the generated fuel vapor to reach the ignition point. It has a big drawback that it produces white smoke and unpleasant odor due to fuel vapor, and since it takes a long time, you have to rely on a 100-volt AC power source other than dry batteries, and you need a wiring cord for the burner to carry it around. It's inconvenient.

The device disclosed in Japanese Utility Model Publication No. 47-10603 has a problem that it takes a considerable time to ignite even if a notch is provided, and white smoke or odor is generated.

Further, in the ones shown in FIGS. 4 and 5, since the notch 31 of the non-combustible fiber core 30 is easily deformed, the filament of the ignition heater 33 and the notch 3 serving as an ignition portion.
The distance from the inner wall of No. 1 is unstable and ignition is not reliable. In addition, since the non-combustible fiber core 30 is fluffed,
The cutout 31 is also fluffed, the filament of the ignition heater 33 comes into contact with the fluff, the heat of the filament of the ignition heater 33 is lost, and it is difficult for the cutout 31 to become red hot. Ignition heater 3
There is a problem that the filament of No. 3 is hard to be protected and is easily broken.

6 and 7, the through hole 3 is shown.
Ignition heater 38 penetrated by 7 is kerosene suction core 35
Since it is in contact with the heat sink, it takes time until the temperature rise required for ignition cannot be ignited quickly, and further, both ends 39, 39 of the ignition heater 38 have both wall surfaces of the kerosene suction core 35. Since it is more protruding, there is a problem that it cannot be used as a core for an oil stove or an oil stove in which the core can be moved up and down to adjust the heating power.

The present invention solves the above-mentioned problems, and can ignite quickly and reliably without deteriorating the ignition performance for a long period of time, suppress the generation of odor during ignition as much as possible, and further raise and lower the wick. The purpose of the present invention is to obtain a wick for a burning appliance which is convenient to use and can be used in a burning appliance capable of adjusting the heating power.

[0014]

In the core for a combustion instrument constructed as described above, the inner peripheral edge 6 facing the metal filament 5 for ignition provided in the ignition window 4 is made of the heat-resistant hard plate 2 having fuel permeability. Therefore, when the ignition metal filament 5 is red-heated, the inner peripheral edge 6 opposite thereto is heated, the fuel is evaporated, and ignition is instantaneously performed. The ignited fire spreads all around the upper edge 14 of the heat resistant core 3, and the ignition operation ends.

A ceramic sintered body in which a heat-resistant core 3 is formed of the sheet-like body 2, an ignition window 4 is formed slightly below the upper edge 14 of the heat-resistant core 3, and an ignition metal filament 5 is provided in the ignition window 4. 8 is attached, and the ignition metal filament 5 is attached through the end portions 22 and 22 at both ends thereof, and the ignition metal filament 5 extends along the inner peripheral edge 6 of the ignition window 4 and the ignition metal filament 5 and the end. The parts 22 and 22 are fixed in the ignition window 4 so that they do not protrude from the heat-resistant core 3, and the ignition metal filament 5 is opposed to the inner peripheral edge 6 of the ignition window 4 with a small gap 15. The heat-resistant core 3 of the embodiment shown in FIG. 1 is entirely formed of the heat-resistant hard plate-like body 2 described above, and the heat-resistant core 3 of the embodiment shown in FIGS.
The heat-resistant hard plate-like body 2 is made of glass fiber, flame resistant fiber,
It is formed by interposing between non-combustible core material main plates 7 made of woven fabric / knitted fabric mainly composed of ceramic fibers. Further, 9 is a fuel-wicking core made of cotton fiber or the like having good fuel-wicking characteristics, and a large number of cutting strips 10, 10 ... Are provided so that bending and stretching can be easily performed when the core is moved up and down. Is. Reference numeral 11 is an upper and lower connecting portion.

The heat-hardened heat-resistant hard plate-like body 2 is hard to be deformed easily even when an external force such as bending is applied, and when the lower end is immersed in a fuel such as kerosene, the fuel sucks up due to a capillary phenomenon. If the heat-resistant hard plate-like body 2 is compressed to increase the density, it is possible to raise the temperature.
The fuel wicking performance can be further improved.

Further, at the time of heat curing, it is preferable to form an arc shape in accordance with the shape of the gap between the inner core cylinder and the outer core cylinder of the combustion instrument (not shown).

As the thermosetting resin, a phenol resin, a melamine resin, a urea resin, an epoxy resin or the like can be used, but the phenol resin is most preferable.

Further, the heat-resistant hard plate-like body 2 and the core material main plate 7 are connected to each other via a connecting tool 16 such as stitching, metal fittings, and adhesion.

Further, the inner peripheral edge 6 of the ignition window 4 which faces the ignition metal filament 5 is smooth without fluffing, and the ignition window 4 is exposed from at least a part of the ignition window 4 during ignition operation. It may be provided in a position on the part and housed in the pan after ignition. Further, the ignition window 4 can be provided by cutting out with a punching blade such as a punch.

Further, the ignition metal filament 5 has a linear shape.
Either of the coil shapes may be used, but the coil shape is preferable because it tends to glow red.

The material of the metal filament 5 is platinum wire,
A nichrome wire, a stainless wire, or the like having resistance to oxidation is used, but a platinum wire which has an oxidation catalytic action and causes the filament to glow red by self-heating is the most preferable.

Further, since attaching the ignition metal filament 5 directly to the ignition window 4 of the heat-resistant hard plate member 2 requires complicated work, it is attached to the ceramic sintered body 8 and attached to the ignition window 4. .

Further, the ceramic sintered body 8 is provided with a notch portion 21 which is partially cut out, and the notch portion 21 has terminal portions 22, 22.
The metal filament 5 for ignition is stretched through the.

The small gap 15 at the inner peripheral edge 6 of the ignition window 4 which faces the ignition metal filament 5 is 0.3 to 5 mm, preferably 1 to 3 mm. If this distance is too short, too much fuel vapor is generated, and the mixture ratio of fuel vapor to air is too high to cause ignition, and if it is too far, too little fuel vapor is caused to cause ignition.

To attach the ceramic sintered body 8 to the ignition window 4, there are means such as adhesion and metal fitting, but the one shown in FIG.
20 are provided so as to protrude, and the needle portions 20, 20 ... are bitten into the inner peripheral edge 6 and adhered via the heat-resistant adhesive 17 so as not to be unintentionally detached.

Further, the electric power is supplied to the ignition metal filament 5 at the time of ignition by using a dry battery as a power source and directly connecting it to the ignition metal filament 5 with a thin conductive wire (not shown).

An ignition window 4 composed of a heat-resistant hard plate 2
However, the part exposed from the fire tray (not shown) at the time of combustion is heated to around 800 ° C during empty heating (operation to cut off the fuel and burn off the fuel in the core to remove tar). Therefore, there is a possibility that the thermosetting resin is burned out and the shape of the core material plate 1 formed of glass paper or the like is impaired. However, as a result of the experiment, as shown in FIGS. It was possible to prevent the deformation of the form by hooking with a glass fiber thread 18 or by impregnating with a heat resistant inorganic adhesive 19 as shown in FIG.

[0029]

The present invention has the above-mentioned structure, and the inner peripheral edge 6 of the ignition window 4 opposed to the ignition metal filament 5 is provided.
Consists of glass paper, ceramic paper, felt mainly composed of glass fiber / flame resistant fiber / ceramic fiber, woven / knitted material mainly composed of glass fiber / flame resistant fiber / ceramic fiber, and the core material plate 1 is thermosetting Since it is formed by perforating the heat-resistant hard plate-like body 2 which is impregnated with the initial condensate of the resin and is thermoset, the inner peripheral edge 6 of the ignition window 4 has no fuzz and is smooth. The distance from the ignition metal filament 5 can be set accurately, and the heat-resistant hard plate-like body 2 contains a suitable amount of fuel because it has fuel permeability, and its surface is heated by the ignition metal filament 5. The fuel quickly evaporates from the fuel and is ignited easily and quickly.

Further, the fuel supply to the heat-resistant hard plate-like body 2 above the ignition window 4 is not sufficient to maintain normal combustion due to the existence of the ignition window 4, and is always in an empty state. As a result, even if the fuel is burned using a fuel containing a bad component such as defective kerosene, the tar is not significantly attached to this portion, and stable and reliable ignition is performed.

Further, in the small gap 15 at the inner peripheral edge 6 of the ignition window 4 which faces the metal filament 5 for ignition, if this distance is too short, too much fuel vapor is generated, and the mixing ratio of fuel vapor to air is large. It is difficult to ignite when it is too high, and it is difficult to ignite when it is too far. However, the distance between the metal filament 5 for ignition and the inner peripheral edge 6 facing the same does not change even after long-term combustion. , Because the ignition is always stable and reliable, and the ignition is quick,
The fuel vapor is not dissipated to the surroundings, and no white smoke or odor is generated during ignition.

Furthermore, since it consumes less electric power and can ignite quickly, it consumes less power, the dry cell can be used without replacement for a long time, and a 100-volt AC power source is not required. It is convenient to carry.

Further, the ignition metal filament 5 is housed in the ignition window 4 of the heat-resistant hard plate-shaped body 2. The ignition metal filament 5 is ignited through the ends 22, 22 at both ends thereof. The filament 5 extends along the inner peripheral edge 6 of the ignition window 4 and the ignition metal filament 5 and the end portions 22, 2
Since 2 is fixed in the ignition window 4 so that it does not stick out from the heat resistant core 3, contact with other obstacles or the like is less likely to occur, and damage such as disconnection or deformation is less likely to occur. It is suitable as a core for petroleum stoves and petroleum hobs that can be moved up and down to adjust the heating power.

Further, the burning instrument of the oil stove and the oil stove has different core sizes depending on the manufacturers, and the position from the upper edge 14 of the ignition window 4 is somewhat different, but the ignition window 4 is formed. The heat-resistant hard plate 2 is made of glass paper, ceramic paper, glass fiber, flame resistant fiber, ceramic fiber-based felt, glass fiber, flame resistant fiber, ceramic fiber-based woven fabric, knitted fabric, etc. Since it is formed by impregnating the core material plate 1 with the initial condensate of thermosetting resin and thermosetting, it is easy to cut with a blade and can be cut with a punching blade such as a punch. The workability is easy, the mounting position of the ignition window 4 can be appropriately selected, and the ignition can be surely performed.

Although the metal filament 5 for ignition is directly attached to the ignition window 4 of the heat-resistant hard plate-shaped body 2, complicated work is required, but it is attached to the ceramic sintered body 8 and attached to the ignition window 4. Therefore, the work is easy, and the ignition metal filament 5 is prevented from being deformed for a long period of time, so that the ignition can be reliably performed.

That is, according to the present invention, the inner peripheral edge 6 of the ignition window 4 has no fluff, and the distance between the ignition window 4 and the metal filament 5 for ignition can be accurately set. Since it has a proper property, it contains a proper amount of fuel, and the fuel is quickly evaporated from the surface by heating from the ignition metal filament 5, and is easily and quickly ignited, and further, a fuel containing a bad component such as defective kerosene is used. Even when it burns, the tar does not significantly adhere to the inner peripheral edge 6 of the ignition window 4, and stable and reliable ignition is performed, and the distance between the metal filament 5 for ignition and the inner peripheral edge 6 that opposes is long-term combustion. It does not change even if it goes, it can always steadily and reliably ignite, and because it is ignited quickly, fuel vapor is not dissipated to the surroundings and white smoke and odor at the time of ignition are not generated. And In addition, it consumes less power because it can be ignited quickly with a smaller amount of power, and the dry cell can be used without replacement for a long time, which is convenient for carrying a burning appliance, and the metal filament 5 for ignition and the terminals 22, 22 are Since it is fixed in the ignition window 4 so that it does not protrude from the heat-resistant core 3, contact with other obstacles or the like is less likely to occur,
It is less likely to suffer damage such as wire breakage and deformation, and is also suitable as a core for oil stoves and oil stoves that raise and lower the core to adjust the heating power, and is easy to cut with a blade and punched like a punch. It can be cut out by a blade and is easy to work, the mounting position of the ignition window 4 can be appropriately selected, and the ignition can be reliably performed, and the ignition mounted on the ceramic sintered body 8 is also possible. The metal filament 5 for use has an industrial effect such that the mounting work is easy, the deformation is prevented for a long period of time, and the ignition is reliable.
