ている。2. Description of the Related Art A conventional oil combustor of this type is disclosed in, for example, Japanese Utility Model Publication No. 47-31.
As shown in Japanese Patent No. 217, the structure is as shown in FIG. That is, the tip of the flat wick 3 held by the fire tray 2 is exposed at the lower end of the flat combustion chamber 1 having a large number of air holes in the side wall, and the outside of the combustion chamber 1 is partially covered. An outer cylinder 5 having a glass plate 4 is provided. 6
Is a red heat coil, and 7 is a red heat net. The combustion chamber 1 has a rectangular or elliptical cross section that does not change in the vertical direction.

There was a problem of causing a bias. That is, when a part of the flat wick 3 is ignited by an electric heater or the like, the flame spreads in the longitudinal direction of the wick 3 and increases the fuel vaporization amount of the whole, but the fuel vaporization amount does not increase rapidly, and the combustion amount increases. As a result, a concentrated flame is formed in the central portion in the longitudinal direction of the combustion chamber 1 according to the draft force generated by heat. This state continues until the amount of fuel vaporized from the wick 3 becomes sufficiently large and the inside of the combustion chamber 1 is filled with the fuel gas and the combustion exhaust gas, and during that period, a large amount of carbon monoxide, odor, soot, etc. is generated due to incomplete combustion. There was a problem of doing.
本発明は上記問題を解決し、点火時において速やかに均
一燃焼へ移行し、一酸化炭素、臭気、スス等の発生を防
止しようとするものである。The present invention is intended to solve the above problems, to promptly shift to uniform combustion during ignition, and prevent the generation of carbon monoxide, odor, soot, and the like.

A large-diameter air hole array is formed on the side wall of the combustion chamber.
作 用 上記技術的手段による作用は次の様になる。Operation The above-mentioned technical means work as follows.

る。The narrow space provided in the lower part of the combustion chamber spreads the fuel gas and flame immediately after ignition in the lateral direction immediately after ignition, ensures uniformity in the longitudinal direction and prevents concentrated flame in the central part. The large-diameter air hole array enables the flame to move quickly from the lower part to the upper part of the narrow space, prevents the release of unburned gas, and suppresses the generation of carbon monoxide and odor.
実施例 以下、本発明の一実施例について、添付図面に基づき説

配設されている。In FIG. 1, 11 is a flat-shaped wick, and the upper part is the fire tray 1
It is pinched by 2 and the tip projects upward, the lower part is tank 13
It is housed inside and immersed in fuel. Further, the wick 11 is configured to move up and down in association with the rotation of the knob 14. A horizontally long flat combustion chamber 16 having a large number of air holes 15 is placed on the fire tray 12, and an outer cylinder 17 is provided outside the combustion chamber 16. A glass plate 18 is arranged at the upper part of the front surface of the outer cylinder 17 so as to face the red heating part 16 a provided at the upper part of the front surface of the combustion chamber 16.

いる。Here, a pressure suppression plate 19 is provided at a position above the tip of the wick 11 below the combustion chamber 17, and a narrow portion 20 is formed. On the side wall of the combustion chamber 16 near the narrow portion 20, the side wall of the combustion chamber 16 is provided.
An air hole row 15a having a diameter larger than that of the air holes 15 at the bottom is formed at least. Further, the combustion chamber 16 directly above the air hole array 15a
A wind control plate 21 having an opening 21a is attached to the outer wall surface.
上記構成において、次に作用を説明する。Next, the operation of the above structure will be described.

が避けられ、全幅略均一の上昇気流となし得る。The fuel vaporized from the wick 11 has air holes 1 in the combustion chamber 16.
It is supplied with air from 5, 15a and burns while being mixed. At the time of ignition, when a part of the wick 11 is ignited, the flame spreads along the wick 11, a flame is formed over the entire length of the wick 11, and vaporization of fuel is promoted. The vaporized fuel, the air flowing in through the air hole 15 near the wick 11, and the combustion exhaust gas try to rise due to the draft generated in the combustion chamber 16. However, since the pressure suppression plate 19 is above, the pressure suppression plate 19 The lower part of the combustion chamber 16 below becomes a semi-closed space, and the pressure volume-expanded by the combustion heat acts in the lateral direction (longitudinal direction) to homogenize the flame in this space. Therefore, it is possible to prevent the standing flame from concentrating in the central portion of the combustion chamber 16, and to obtain an ascending airflow having a substantially uniform width.

燃ガスや一酸化炭素、臭気等を点火時に多発することは
防止できる。However, since the cross-section of the combustion chamber 16 is made small in the narrow space 20, the fuel-air-exhaust gas mixture (G) is concentrated here as shown in FIG. 2 to increase the flow velocity. Therefore, immediately after ignition, the flame below the pressure suppression plate 19 does not rapidly move upward, and the narrow portion 20 is in a misfire state, and tends to be in a state of releasing unburned gas. In particular, the narrower the narrow portion 20, the greater the effect of homogenizing the flame, but this flame transfer is delayed, and unburned gas is discharged for a long time, and carbon monoxide and odor are remarkable. Here, by providing the large-diameter row of pores 15a on the side wall of the combustion chamber 16 directly above the narrow portion 20,
A large amount of air (A) flows into the mixture (G) and air (A)
And promotes the mixing of the mixture into a flammable state, and the row of pores 15a.
Since the diameter is large, the flame (F) is likely to be stably formed (flame holding), and this flame (F) serves as an ignition source, and thereafter, it is possible to smoothly proceed the upper combustion. Thus, the flame transfer between the upper and lower sides of the narrow portion 20 is promptly performed, and it is possible to prevent the unburned gas, carbon monoxide, odor, etc. from being frequently generated at the time of ignition.

とができる。Further, when the wind control plate 21 mounted directly above the outside of the large-diameter pore array 15a interrupts the upward flow of air (A) and converts it into a dynamic pressure toward the inside of the combustion chamber 16, the pore array 15a The inflow of air (A) is further promoted, and the flame holding effect can be increased.

である。The position of the pore row 15a with respect to the narrow portion 20 may be on either the front or rear wall surface, but if the pore row 15a is provided on the side wall facing the protruding side of the pressure suppression plate 19 as shown in FIG. The mixing of G) and air (A) streams is more accelerated and effective.
