Abstract

PURPOSE:To improve ignition performance to a satisfactory extent by lifting a wick up to a position where its upward movement comes to a halt automatically, charging a metal filament, lowering the wick after ignition, stopping the charge, and controlling the position of the wick so that it may be proper to ordinary combustion. CONSTITUTION:When a wick 1 is hoisted by manipulating a lifting means 10 and an ignition window 3 is exposed from a wick housing member 9, and the wick 1 is further hoisted upward up to the point where no lifting means 10 is allowed to operate, an ignition filament 6 installed in the ignition window 3 is charged with electric power. An upper part inner periphery edge 4, which faces the ignition metal filament 6 is heated when the ignition metal filament 6 becomes red hot, and fuel is evaporated, thereby igniting spontaneously. Then, when the wick 1 is lowered for ordinary combustion, the charge to the ignition metal filament 6 is halted. The heating power can be controlled by lifting or lowering the wick 1 under control so that the ignition window 3 may be positioned at the wick housing 9 during the ordinary combustion. When the entire wick 1 is housed inside the wick housing 9, the flames will go out.

Description

[Detailed Description of the Invention] <Industrial Application Field> F! ! I! i
7α for combustor that can be operated smoothly and quickly with repeated operations
It concerns fire methods.

<Prior art> In order to ignite a wick in a combustion appliance, there are two methods: one is to bring a red-hot ignition heater close to the wick and ignite it directly, and the other is to use an ignition heater built into the wick itself to cause a red-hot flame. 2f
! There is IM, and in the latter method, both ends of a 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 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. S4-21010).

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 core body, covering the entire inner circumference of one end of the core (see Japanese Utility Model Publication No. 45-310).

One or two or more notches are provided on the upper edge of the core, and a part of the heating wire is exposed through these notches (Japanese Utility Model Publication No. 47-10603, Publication of Utility Model Publication No. 47-302 (i)).
(See Publication No. B).

A notch is formed on the upper edge of the non-combustible fiber 44##A core, and a filament with both ends of the filament connected to the end of the feeder line, which is sewn inside the core and connected to the notch, is cut out. Fixed inside (Refer to Utility Model Application No. 6l-696 (No. 35)).

etc. are known.

<Problems to be solved by the invention> By the way, 111! In the conventional method described above, there are problems such as the fluff of the wick coming into contact with the filament of the ignition heater, causing the filament to be cut, and the heat being absorbed by the fluff, making it difficult to get red-hot. As the latter method,
Special Publication No. 52 22453, Special Publication No. 54-2101
What is disclosed in Publication No. 0 is that /; Deformation due to contact,
The heat of combustion, especially the high temperature during dry firing, can cause thermal deformation of the glass fibers in the fluff, volume deformation due to loss of combustible components such as rayon cloth or flame-resistant fibers, and even long-term combustion.
Due to shrinkage and deformation due to tar formation due to defective kerosene combustion, etc., the distance from the heat generating part of the large V heater changes.
There is a problem that the ignition performance becomes seriously unstable, and the method disclosed in Japanese Utility Model Publication No. 42-21424 heats and evaporates the fuel contained in the wick using a coated electric heating resistance wire provided inside the wick. Since the steam is heated and ignited using a separate electric heating resistance wire in the initial combustion zone, the power required is naturally large, and there is a problem that a normal 100 volt AC power source must be used and a wiring cord is required. . In addition, the fuel is heated and evaporated using a coated electric heating resistance wire.
There is also the problem that it takes a long time for four people to be heated (heated with another electric resistance wire in the initial combustion zone).

(Usually required), ′, +: Fire required Samurai time required is about 3 seconds. ) During this period, there is a major drawback that white smoke and unpleasant odors are generated due to fuel vapor.
Since the device shown in No. 1111 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 major drawback that white smoke and unpleasant odors are generated due to fuel vapor.
Since the time required is long, it is necessary to rely on a 100 Bordeaux AC power source other than dry batteries, and the combustor J1 requires a wiring cord, making it inconvenient to carry. Also, Jikko Sho 47-1
The method disclosed in Publication No. 0603 has problems such as -x taking a considerable amount of time to ignite even if a bonfire is provided, and producing white smoke and odor.
The device disclosed in Publication No. 7-30268 requires a large amount of power because the heating wire is arranged all around the core.
Since it cannot be ignited using batteries, it requires a wiring cord, making it inconvenient to carry. In addition, with this method, it is difficult to fix the heating wire in a predetermined position, and it is not practical. Since the notched part is easily deformed,
The distance between the ignition filament and the inner wall of the notch that serves as the ignition site is unstable, making ignition difficult. Also, since the core made of non-flammable fiber is fuzzy, 1. Heat from the ignition filament is lost when the filament comes into contact with the fluff, making it less likely to become red hot.

Furthermore, the upper part of the notch is open;
I: There is a problem that the heater is difficult to maintain, is difficult to maintain, and is easily disconnected.

In other words, in the method of igniting by incorporating the ignition heater into the wick itself, the fuzz part at the ignition part becomes deformed, the distance between the heat generating part of the ignition heater and the fuzz part changes, and the ignition performance becomes unstable. Become.

There is a delay between the time the heater is turned on and the time it is ignited, and it takes a while to open.

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

The ignition filament is easily broken.

Although the electric 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 because it uses a 100-volt AC power source, a wiring cord 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-mentioned problems and improves ignition performance to improve the RF! ■The aim is to learn all six ways to make convenient combustion appliances.

<Means for solving the problems> In order to achieve the above object, +i
The lighting method is to drill an ignition window 3 in the core body 1 at a position slightly below the upper edge 2, and within the ignition window 3, there is an upper inner peripheral edge 4 and a small gap 5, and a metal filament for rapid fire is inserted. 6 are arranged opposite each other, and the core body 1 is placed in a core storage portion 9 formed by a core guide tube 7 and a core outer tube 8.
is housed so that it can be raised and lowered via the lift operation body 10, and the lift operation body 10 is operated in a direction to raise the core body 1, so that the core body 1 is exposed from the core storage part 9 of the α large window 4 and raised and lowered. Operating body 1
0 until the operation in the upward direction automatically stops, energizing the metal filament 6 for ignition, and after igniting the upper inner peripheral edge 4 of the ignition window 3, the lifting operation body 1
0 in the direction of lowering the core body 1 to stop the energization to the ignition metal filament 6, and then operate the elevating operation body 10 so that the α large window 3 is located in the core storage part 9. Core body 1
The core body 1 is exposed from the core storage part 9 as the core body 1 is lowered.
The position of the upper edge 2 of the combustion chamber is adjusted to suit normal combustion.

<Example> The present invention will be described in detail with reference to the drawings below. 14 is a heat-resistant hard plate-like body, and the heat-resistant hard plate-like body 14 is:
〃Russ vapor, ceramic vapor, felt mainly made of glass fiber, flame resistant fiber, ceramic fiber, textiles mainly made of glass fiber, flame resistant fiber, ceramic II & fiber.
A core material plate made of a knitted fabric or the like is impregnated with an initial condensate of a thermosetting resin and then thermally cured to form a heat-resistant hard plate-like body 14 having fuel permeability, or a porous ceramic material is used as a fuel source. A heat-resistant hard plate-like body 14 having permeability is formed. In addition, the whole or part of the heat-resistant core 15 is formed into a heat-resistant hard plate-like body 14, and an ignition window 3 is bored at a position slightly below the upper edge 2 of the heat-resistant hard plate-like body 14. The ignition metal filament 6 has a small gap 5 with the upper inner circumferential edge 4 of the ignition window 3, and is disposed oppositely to form the core 1. Fifth
The heat-resistant core 15 of the embodiment shown in the figure is a heat-resistant hard plate-like body 1
4, and the heat-resistant core 15 of the embodiment shown in FIG. It is formed interposed between the material main plates 22,
In the embodiment shown in FIG. 7, a ceramic sintered body 23 provided with an ignition metal filament 6 is attached to the α large window 3, and the ignition metal filament 6 is connected to the upper inner peripheral edge 4 of the ignition window 3. They are placed opposite each other with a gap 5 between them. Further, 24 is a fuel wicking core made of cotton fiber or the like having good fuel wicking properties and connected to the lower end of the heat-resistant core 15. A large number of cutting strips 25, 25... This allows for easy bending and stretching when going up and down. Also, 11 is suture/
The upper and lower connections are made using metal fittings, adhesives, etc. However, when the heat-resistant hard plate-like body 14 is made of porous ceramic, stitching is not possible, so the upper and lower connecting portions 11 are made using metal fittings or adhesives. Further, 28 is a reinforcing tape.

In addition, the properties of the heat-resistant hard plate-like body 14 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 thermosetting resin, phenol resin, melamine 05
Although resins, urea resins, epoxy resins, etc. can be used, phenol resins are most preferred.

Furthermore, the connection between the heat-resistant hard plate-like body 14 and the core main plate 22 is performed through a connecting tool 16 such as suture, metal fitting, or adhesive. In this case, stitching cannot be performed, so the connector 16 is fixed with metal fittings or glued.

The upper inner circumferential edge 4 of the ignition window 3 facing the ignition metal filament 6 is smooth and free of fuzz, and the ignition window 3 has 5,
The ignition window 3 is provided at a position exposed from the wick storage part 9 during α-fire fabrication.

Further, the α large window 3 can be provided by cutting it out with a punching blade.

The ignition metal filament 6 is attached to the ignition window 3 at position 1. When making α fire, it must be exposed from the lead storage part 9, but it is inserted into the lead storage part 9 after the test.

The giant metal filament 6 may be either linear or coiled, but coiled is preferred because it is more likely to become red hot.

The ignition metal filament 6 is made of oxidation-resistant materials such as platinum wire, nichrome wire, stainless steel wire, etc., but platinum wire is most preferable because it has an oxidation catalytic action and the filament becomes red-hot due to self-heating.

The ignition metal filament 6 is attached to the ignition window 3 by attaching it to the ceramic sintered body 23, since it requires complicated work to attach it to the α large window 3 of the heat-resistant hard plate-like body 14.
It is preferable to install the

The ceramic sintered body 23 preferably has a structure in which an ignition metal filament 6 is stretched over a notch 21 in which a portion is cut out.

When rubbed in this way, the ignition metal filament 6 becomes
5. It can be easily attached to the ignition window 3 without contacting the upper inner peripheral edge 4 of the ignition window 3.

The small gap 5 between the upper inner peripheral edge 4 of the ignition metal filament 6 and the ignition window 3 is 0.3 to 5I, preferably 1 to 3
+IIm is better. If this distance is too close, 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 it is too close, there will be too little fuel vapor, making it difficult to ignite.

To attach the ceramic sintered body 23 to the ignition window 3, adhesive and
Although there are means such as metal fittings, the one shown in FIG. 8 has several needle parts 20, 20, etc. around the ceramic sintered body 23.

Further, 29 is a device body, which includes a combustion tank 30, a wick guide tube 7,
Outer core 1: A core storage section 9 made of J8 is provided, and a core storage section 9 is provided.
The core body 1 is housed in such a manner that it can be raised and lowered based on the operation of the raising and lowering operating body 10.

Further, the lower end of the fuel suction core 24 forming the core body 1 is immersed in fuel 26. Also, the core body 1 shown in FIGS. 1 to 3
is in the ignition position, and the ignition window 3 is in the wick storage part 9.
exposed from.

Leads #iI27.27 are connected to the terminals 12.12, and the leads #a27 and 27 are interlocked with the lifting operation body 10 via the banking 18 provided in the core outer cylinder 8, The core body 1 is connected to the battery 13 based on the operation of the switch 19 at the uppermost position of the core body 1 where it cannot be moved. switch 1
9 is opened, the energization to the metal filament 6 for ignition is stopped, and the amount of exposure of the heat-resistant wick 15 from the wick storage g9 is controlled by the lifting operation body 1.
The firepower can be adjusted by increasing or decreasing it at 0, and during normal combustion, the ignition window 3 is closed to the wick storage section 9.
It is held in a position inside.

In addition, the means for lifting and lowering the core body 1 and the metal filament 6 for ignition
The means for energizing is not limited to what is shown in the drawings.

Operation> The core body 1 configured as described above is raised by operating the lift operation body 10, and the α large window 3 is exposed from the core storage part 9, and the position where the lift operation body 10 cannot be operated is reached. The ignition metal filament 6 installed in the ignition window 3
1. The upper inner peripheral edge 4, which is energized and opposed to the ignition metal filament 6, is composed of a heat-resistant hard plate-like body 14 that is permeable to fuel. When the metal filament 6 for open flame is heated red-hot, the opposing upper inner peripheral edge 4 is heated, the fuel evaporates, and ignition is instantaneously performed. The directly lit flame spreads all around the upper end of the wick 1, and the ignition operation ends.Next, when the wick 1 is lowered for normal combustion, the energization to the metal filament 6 for ignition is stopped, and the ignition operation is completed. The firepower is adjusted by adjusting the top and bottom of the body 1, and during normal combustion, the ignition g
3 is located in the core storage section 9, and the entire core 1 is placed in the core storage section 9.
If you store it inside, it will extinguish the fire.

<Effects of the Invention> The present invention has the above-described configuration, and when the core body 1 is raised by the lifting/lowering operation member 10, the ignition metal filament 6 is passed through.
1, the fuel quickly evaporates from the upper inner periphery Ai4 of the α large window 3 due to the heating from the ignition metal filament 6, and this is coupled with the fact that the ignition window 3 is exposed from the wick storage part 9 when electricity is applied. The air required for ignition is sufficiently supplied, making it easy to ignite.
It ignites quickly and instantly. Furthermore, the distance between the ignition metal filament 6 and the opposing upper inner circumferential edge 4 does not change even after long-term combustion, so that stable and reliable ignition can always be achieved. Furthermore, the fuel supply to the core body 1 above the ignition window 3 is insufficient to maintain normal combustion due to the presence of the ignition window 3.
In fact, it became an empty fire. 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 consumes less electricity and can quickly generate a 7-χ fire, so the dry cell battery can be used for a long time without replacing, and there is no need for a 100 volt AC power supply, so there is no wiring cord, making it easy to carry. It's convenient. Furthermore, since the ignition metal filament 6 is housed within the ignition window 3 of the core body 1, it is less likely to come into contact with other obstructive objects, and damage such as wire breakage and deformation is less likely to occur. Also, since ignition occurs quickly, fuel vapor is not diffused 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 the heater is brought close to the wick through the gap created between the burner and the fire pan to ignite, it is possible to ignite without tilting the burner. Because of this, no soot is generated when igniting.

In addition, if the lifting/lowering operation body 10 is operated, that is, rotated in the case shown in the figure, and the core body 1 is lowered even slightly from the raised position, the energization to the metal filament 6 for ignition is stopped, reducing wasteful power consumption as much as possible. The firepower can be adjusted by adjusting the amount of exposure from the wick storage part 9 of the upper end #j:2 of the body 1 using the lifting/lowering operation body 10, but during normal combustion, the metal filament 6 for ignition is stored in the wick storage. Since the ignition metal filament 6 is located inside the part 9 and is not exposed to the burning flame, the ignition metal filament 6 is prevented from burning.
It can withstand gI f acceptance.

Furthermore, since the α fire only needs to be raised by raising the core body 1 until the lifting operation body 10 can no longer be operated, the lifting operation body 1 is
The operation is easy as there is no need to make manual adjustments for the operation of 0, and after ignition, by operating the lifting/lowering operation body 10 in the direction of lowering the core 1, the energization to the metal filament 6 for ignition is stopped. The ignition operation can be easily performed and the operation is extremely easy.
