Abstract

PURPOSE:To reduce the chance of contact with interfering articles, and to reduce possible damages such as discontinuation and deformation, etc., by starting the electrical supply to the metallic filament for ignition at the time of exposing the ignition window disposed in the wick, and stopping the electrical supply to said ignition filament at the time of lowering the ignition window into the wick retracting section. CONSTITUTION:The electrical supply to the metallic filament 5 for ignition disposed in the ignition window 4 is started when the wick 3 is raised by operating the control handle 25 to expose the ignition window 4 out of the wick retracting section 24. The upper inner rim 6 opposite to said ignition filament 5 consists of a heat-resistant hard plate 2 which can suck the fuel. Therefore, when the ignition filament 5 becomes red hot, the upper inner rim 6 is heated to cause the fuel to evaporate for an instant ignition. The flame so ignited propagates to the entire length of the upper rim of the wick 3 to complete the ignition stage. For normal operations, the wick 3 is lowered to retract the ignition window 4 into the wick retracting section 24, whereupon the electrical supply to the ignition filament 5 is stopped. The flame can be extinguished when the entire wick 3 is retracted into the wick retracting section 24.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to combustors such as kerosene stoves and kerosene stoves, which have significantly improved α-fire performance.

Conventional technology There are two ways to ignite a wick in a combustor: one involves bringing a red-hot ignition heater close to the wick, and the other uses an ignition heater built into the wick itself to ignite the wick. As for the latter method, both ends of the flat core material are connected in an annular shape by a connecting member via an ignition heater with the heat generating part facing upward and a Fl11 spacing plate located at the bottom of the ignition heater. Annular cores formed by connecting
(See Japanese Patent Publication No. 22453 and Japanese Patent Publication No. 54-21010).

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 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 prayer bending piece and the basic body, extending over the inner circumference of the metal at the upper end of the core (see Japanese Utility Model Publication No. 45-310).

One or more notches are provided on the upper edge of the core, and a part of the heating wire is exposed through the cutouts (Japanese Utility Model Publication No. 47-10603, Publication of Utility Model Publication No. 47-30268)
(see publication).

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 Application Publication No. 61-69665) 9 etc. are known.

<Problems to be Solved by the Invention> By the way, in the prior art described above, the former means may cause the fluff of the wick to come into contact with the filament of the flaming heater, causing the filament to be cut, or the fluff to generate heat and become red-hot. There were some problems, such as difficulty. In addition, as a means of the latter,
What is disclosed in Japanese Patent Publication No. 22453 and Japanese Patent Publication No. 54-21010 is that both g of the core material corresponding to the ignition part are
The fluff part of Ara is deformed due to contact with the operator's hands and the combustor when the wick is installed in the combustor, and the plus fibers in the fluff part are thermally deformed due to the combustion heat, especially the high temperature during dry firing. ,
The distance from the heating part of the ignition heater changes due to volumetric deformation due to burnout of combustible components such as rayon cloth or flame-resistant fibers, as well as contraction and deformation due to tar formation due to long-term combustion and poor kerosene combustion. There was a problem that the fire performance became extremely unstable, and the
The method disclosed in Publication No. 424 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 that a normal 100 volt AC power supply must be used and a wiring cord is required. Another problem is that it takes a considerable amount of time for the fuel to be heated and evaporated by the coated electric heating resistance wire, heated by another electric heating resistance wire in the initial combustion zone, and ignited directly. (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, fuel vapor produces white smoke and unpleasant odors, which is a major disadvantage, and it takes a long time, so it is recommended to use batteries other than dry batteries.
00 volt AC 1! Both the combustor and the combustor require a wiring hood, making them inconvenient to carry. In addition, the method disclosed in Publication No. 47-10GO3 has problems such as it takes a considerable amount of time to ignite even if a notch is provided, and white smoke and odor are generated.
The one disclosed in Japanese Utility Model Publication No. 47-30268 requires a large amount of electricity because heating wires are placed all around the wick, and since it cannot be ignited with dry batteries, it requires a wiring cord, making it inconvenient to carry. In addition, with this configuration, it is difficult to fix the heating wire in a predetermined position, and it is impractical. Since the portion is easily deformed, the distance between the ignition filament and the inner wall of the notch, which serves as one ignition site, is unstable, and ignition is not reliable. In addition, since the noncombustible fiber core is fluffed, the fluff contacts the open flame filament and the heat of the ignition filament is lost, making it less likely to become red hot.

Furthermore, since the upper part of the notch is open, it is difficult to protect the 7α heater, and the wire is easily broken.

That is, in the method of igniting by incorporating an ignition heater into the wick itself, 1. Due to the deformation of the fluff portion of the open flame portion, the distance between the heat generating portion of the ignition heater and the fluff portion changes, and the performance of the two-burner flame becomes significantly 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 power 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 hood is required, making it inconvenient to carry the combustor. (Can only be used where there is a power source), etc., α
was there.

This invention solves the above problems and aims to provide a combustor that is convenient to use by significantly improving ignition performance.

<Means for Solving the Problems> In order to achieve the above object, the combustor of the present invention uses a heat-resistant hard plate-like body 2 having fuel permeability for the whole or part of the heat-resistant core 1. together with the upper edge 1 of the heat-resistant hard plate-like body 2
The ignition window 4 is located slightly below the ignition window 4.
An ignition metal filament 5 is provided in the ignition window 4, and the ignition metal filament 5 is disposed opposite to the upper inner peripheral edge 6 of the ignition window 4 with a small gap 15 to form the core body 3, and is connected to the core guide @22 and outside the core. The core body 3 is raised and lowered into the core storage part 24 formed by the tube 23 and the massaging body 2
When the ignition window 4 provided in the wick body 3 is exposed from the wick storage part 24, the ignition metal filament 5 is energized, and the ignition window 4 enters the wick storage part 24. It is formed so that the energization to the ignition metal filament 5 is stopped when it descends.

<Example> The present invention will be described in detail with reference to the drawings below. 2 is a heat-resistant hard plate-like body, and the heat-resistant hard plate-like body 2 is made of lath paper, ceramic paper, glass M&fiber, flame-resistant AI

Alternatively, a heat-resistant hard plate-like body 2 having fuel permeability is formed using porous ceramics as a material. In addition, the whole or a part of the heat-resistant core 1 is made into a heat-resistant hard plate-like body 2, and the upper edge 1 of the heat-resistant hard plate-like body 2
There are nine ignition windows 4 located slightly below the ignition window 4.
A metal filament 5 for ignition is provided at

· is provided so that the core body 3 can be easily bent and stretched when moving up and down. Further, numeral 11 indicates the upper and lower connecting portions that are sewn, fastened with metal fittings, adhesive, etc. However, when the heat-resistant hard plate-like body 2 is made of porous ceramic, sewing cannot be performed, so the upper and lower connecting portions 11 are fastened with metal fittings or glued. This is done by Further, 28 is a reinforcing tape.

In addition, the properties of the heat-resistant hard plate-like body 2 are such that it does not easily deform even when external forces such as bending are applied, and when the lower end is immersed in fuel such as kerosene, the fuel can be drawn up to the upper part by capillary action.

Furthermore, when molding, it is preferable to mold the core into an arcuate shape in accordance with the shape of the gap between the core guide tube and the core outer tube of the combustor.

As the thermosetting resin, 7-ester resin, melamine resin, urea resin, epoxy resin, etc. can be used, but phenol is the most preferable. j (It's fat.

In addition, the connection between the heat-resistant hard plate-like body 2 and the core material main plate 7 is by suture.
This is done through a connecting tool 16 such as a metal fitting or adhesive, but when the heat-resistant hard plate-like body 2 is made of porous ceramic, suturing is not possible, so the connecting tool 16 is a metal fitting or adhesive. It is.

The upper 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 portion where the ignition window 4 is exposed from the wick storage portion 24 during ignition operation. The six-pronged ignition window 4 can be cut out using a punching blade.

The metal filament 5 for ignition must be installed in the ignition window 4 so that it is exposed beyond the wick housing 24 during repeated ignition operations, but after ignition it must be placed several times inside the wick housing 24. be.

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.

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.

Since it requires complicated work to attach the ignition metal filament 5 to the ignition window 4 of the heat-resistant hard plate 2, it is possible to attach the ignition metal filament 5 to the ignition window 4 by attaching it to the ceramic sintered body 8. preferable.

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

With this configuration, the ignition metal filament 5 is
．． It can be easily attached to the direct fire window 4 without contacting the upper inner peripheral edge 6 of the direct fire window 4.

The small gap 15 in the upper inner circumferential edge 6 of the ignition window 4 facing the ignition metal filament 5 is preferably O13 to 51111111, preferably 1 to 3IIIfi. 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 ceramic sintered body 8 can be attached to the ignition window 4 by means of adhesion, metal fittings, etc., but the method shown in FIG. 8 has several needle parts 20, 20, . The needle portions 20, 20, . . . are provided in a protruding manner, and the needle portions 20, 20, .

Further, 29 is a device body, which includes a combustion tank 30 and a core guide tube 22.
, a core storage part 24 made of a core outer cylinder 23 is provided, and the core body 3 is stored in the core storage part 24 so that it can be raised and lowered based on the operation of an elevating operation body 25.

Further, the lower end of the fuel suction core 9 forming the core body 3 is immersed in fuel 26. In addition, the position of the wick 3 in the case shown in FIGS.

A lead wire 927.27 is connected to the terminal 12.12, and the lead wire 27.27 is connected to the backing 8 provided on the core outer cylinder 23 to operate the switch 19 which is linked to the lift operation body 25. The switch 19 is connected to the battery 13 based on the structure, and if the core body 3 is lowered even slightly from the raised position by operating the lift operation body 25, the switch 19 opens and the electricity to the ignition metal filament 5 is stopped. The heating power can be adjusted by adjusting the amount of exposure of the wick 1 from the wick storage part 24 with the lifting/lowering operation body 25,
Further, during normal combustion, the ignition window 4 is held in a position within the wick storage portion 24.

In addition, the means for raising and lowering the core body 3 and the metal filament 5 for
The energizing means for the ignition window 4 is not limited to the one shown in the figure. <Function> The wick 3 configured as described above is raised by operating the lifting operation member 25, and the ignition window 4 is exposed above the wick storage portion 24. When the ignition metal filament 5 provided in the ignition window 4 is energized, 1. Upper inner peripheral edge 6 opposite to α-use metal filament 5
is composed of a heat-resistant hard plate-like body 2 that is permeable to fuel, so when the metal filament 5 for ignition is red-hot, the logarithmic upper inner circumferential edge 6 is heated, and the fuel evaporates. ignition takes place. The ignited fire spreads all around the upper end of the heat-resistant wick 3.1. The fire operation ends. Further, when the wick 3 is lowered for normal combustion, the ignition window 4 is housed in the wick housing 24, and the energization to the ignition metal filament 5 is stopped. Moreover, if the entire core body 3 is stored in the core storage section 24, the fire will be extinguished.

<Effects of the Invention> This invention has the above-described configuration, and when the core body 3 is raised by the lifting/lowering operation body 25, α fire metal! fG filament 5
is energized, and by heating from the ignition metal filament 5,
The fuel quickly evaporates from the upper inner peripheral edge 6 of the direct ignition window 4, and together with the fact that the ignition window 4 is exposed from the wick storage part 24 when electricity is applied, the air necessary for ignition is sufficiently supplied. ignites easily and quickly. Further, the distance between the ignition metal filament 5 and the opposing upper inner circumferential edge 6 does not change even during combustion, and ignition can always be performed stably and reliably. Further, the fuel supply to the heat-resistant hard plate-like body 2 above the ignition window 4 is as follows: 1. Due to the presence of the α large window 4, it is insufficient to maintain normal combustion, and the combustion is always in a dry state.

As a result, even when fuel containing bad components such as defective kerosene is used for combustion, there is very little tar attached to this part, and ignition is carried out stably and reliably. In addition, it requires less power and can be ignited quickly, so power consumption is low, dry batteries can be used for a long time without replacing, and there is no need for a 100 port AC power source, so there is no wiring cord.
Convenient to carry. In addition, since the metal filament 5 for open flame is housed within the ignition window 4 of the heat-resistant hard plate-like body 2, it is difficult to come into contact with other objects that may cause an obstruction, thereby preventing damage such as wire breakage or deformation. <111° and ignition occurs quickly, so fuel vapor is not diffused into the surroundings 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 the gap created between the burner and the fire pan, it is possible to achieve vinegar-stop ignition that ignites without tilting the burner. No soot is generated.

Moreover, if the core body 3 is lowered even slightly from the raised position by operating the lifting/lowering mechanism 25, the switch 7 switch 19 will open, the electricity supply to the metal filament 5 for direct fire will be stopped, and the heat-resistant core 1 will be exposed from the core storage part 24. The firepower can be adjusted by adjusting the amount with the lifting/lowering operation body 25, but during normal combustion, the ignition metal filament 5 is lowered into the wick housing 24 and exposed to the burning flame. This prevents the ignition metal filament 5 from being burnt out and can withstand long-term use.
