Abstract

PURPOSE:To make it possible to positively ignite the kerosene stove without lifting a combustion cylinder by providing an ignition heater in which a supply port for supplying air is opened on the peripheral side of an upper filament. CONSTITUTION:By operating a wick lifting and lowering device, a wick 16 is protruded between an outer flame cylinder 4 and a cylinder 17. When the upper end of the wick 16 is positioned between both filaments 30 and 30 and power is supplied to an ignition heater 19, evaporated gas is produced from the wick 16 by the lower filament 30, and the evaporated gas lifting up is suitably mixed with air supplied through a supply port 31 communicating with the inner part of the cylinder 17. The lifting gaseous mixture comes near to the upper filament 30 or comes into contact therewith, and is quickly ignited. Upon this occasion, combustion air flows in through a supply port 18 of the cylinder 17 and a small hole 4A of the outer cylinder 4, and used for ignition and combustion.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides a heater for igniting a lamp wick that can be moved up and down between a wick guide tube and a wick guide outer tube so as to face the wick when it is rising. Regarding the ignition device of a kerosene stove installed in

(b) Conventional technology In general, igniters for kerosene stoves are broadly classified into the following 29 categories. The first method is to lift the combustion tube and bring the ignition heater close to the lamp wick to ignite the ignition.
This is disclosed in Japanese Utility Model Publication No. 4692, Japanese Utility Model Publication No. 55-48278, and the like.

The second method is to ignite without lifting the combustion tube.

In the first method, the combustion tube is lifted to ignite the combustion chamber, so there is a problem in that a large amount of soot or carbon monoxide is generated due to excess air during ignition, creating a foul odor in the room. In the second method, on the other hand, there is little air circulation near the ignition heater, so even if vaporized gas is generated by the heater, the area around the filament of the heater is piled up with vaporized gas, and there is no combustion air to ignite. There was a problem of poor performance. In other words, ignition errors often occurred because an appropriate mixing ratio of vaporized gas and combustion air could not be obtained.

(c) Problems to be Solved by the Invention To solve the above-mentioned problems, the present invention supplies an appropriate amount of air around the filament of the ignition heater without lifting the combustion cylinder, thereby ensuring ignition. This is to ensure that the

B) Means for solving the problem To this end, the present invention provides an ignition heater for igniting a lamp wick that can be moved up and down between a wick guide tube and a window guide outer tube, and is arranged so as to face the lamp wick when it is rising. An ignition system for a kerosene stove equipped with a heater main body made of an insulating material, two pairs of upper and lower conductive wires that are buried within the main body but have portions protruding outside the main body, and a protrusion of the paired conductive wires. The heater body is provided with a supply port for supplying air around the upper filament, and the upper end of the lamp wick when rising is An ignition heater is provided between the two filaments.

(E) When the working lamp wick is placed protruding inside the combustion cylinder, that is, between the outer flame cylinder and the cylinder body, and power is supplied to the ignition heater, both filaments generate heat, especially the lower filament, and vaporized gas is generated from the lamp wick. The vaporized gas and the air from the supply port that communicates the inside and outside of the cylinder are appropriately mixed, and this air-fuel mixture comes into close proximity to or comes into contact with the filament above, and is quickly ignited.

A communication hole (2z...) communicating with the inside of the inner flame tube (2) is opened in the top surface 0]). Also, a communication hole (2z...) is opened in the top surface 0]) which communicates with the inside of the inner flame tube (2).

Then, the upper filament (to) is placed at a position below the position facing the upper filament ■.
Supply port for supplying air to the surrounding area 01) C3υC31
) is provided in the heater main body C751 to communicate between the inside and outside of the cylindrical body tiη. The other ends of the conductive wires are connected to a battery connected to a lightning power source by a switch shown at 1- through a lead 1%1G3, with the left and right conductive wires as a pair.

In this embodiment, the supply port C31) (311C31) is opened between both filaments (7)■, but as shown in FIGS. 7 to 9, it is placed at a position facing the filament gloss above the trap. It may be formed into a vertically elongated shape as shown in FIG. It is sufficient to establish it at an appropriate location in the lower area including the opposing position.

The structure is as described above, and its operation will be explained based on FIG. First, a wick up/down device (not shown) is activated to make the wick (10) protrude into the combustion tube (1), that is, between the outer flame tube (4) and the fin of the tube body, and the upper end of the wick 4 is brought into contact with both filaments (towards). Position [Although not shown, power is supplied to the ignition heater by operating the ignition operating member provided on the front panel etc. Then, the filament (7) (to) generates heat and ignites the lamp wick (161). At this time, the filament circle of the lower blade generates vaporized gas from the lamp wick αe.
This rising vaporized gas is appropriately mixed with air supplied from the supply port GυGDC31) communicating with the inside of the cylinder αn as shown by the arrow. That is, this rising air-fuel mixture comes close to or comes into contact with the filament gloss above, so that it is quickly ignited. Of course, at this time, combustion air also flows into the supply port Qgj of the cylinder fin and the small hole (4A) of the outer flame tube (4) for ignition and combustion.

During combustion, the filament and the heater body (c) are constantly cooled by the air passing through the supply port Gl)C31)C1υ, resulting in good heat resistance and long life.

Also, when replacing the ignition heater α→, first remove the combustion tube (1) by lifting it upward so as to separate it from the top of the plate part 04, and then remove the cylinder body (17) from the top plate a3. .

Loosen the screw (5) □□□ through the communication hole @ and attach the presser metal fitting (
Remove the heater (I!J) from the mounting hole ■ and replace it.

Also, to install the ignition heater (1!J), the reverse operation can be performed, but if the heater C1!J is fixed to the top plate αy with the holding metal fitting (2b) with the IK shell passed through the installation opening (2f). , the heater α9 also serves as a fixing member for the cylindrical body 0D.

(G) Effects of the Invention As described above, the present invention allows the combustion cylinder to approach the upper filament when the mixture of the vaporized gas generated by the filament below the ignition peak and the air from the supply port rises, without having to lift the combustion tube. Or, since they come into contact with each other, ignition can occur quickly and no foul odor will be generated. Further, even during combustion, the filament and the heater body are constantly cooled by the air passing through the supply port, and the filament and the heater body are free from heat resistance problems and have a long lifespan.
