Japanese Patent Publication No. 366 is known, and this is described with reference to the drawings in the publication (see FIG. 4).
A plurality of air holes (2) are opened in a peripheral wall of a bottomed cylindrical combustion cylinder (1), and a vaporization chamber (3) having a gap with the combustion cylinder bottom wall is provided in the combustion cylinder (1). A rotary plate (4) and a fuel supply pipe (5) are provided in (3), and an air port (6) faces the bottom wall of the combustion tube (1). (7) is a blower, (8) ) Is an air chamber, and (9) is an ignition heater. In this device, when ignited, the fuel is scattered by the rotating plate (4), and the atomized fuel strikes the wall of the cold vaporization chamber (3) and reflows, which flows down to the bottom wall of the combustion tube (1) and ignites. It ignites by contacting the heater (9). However, since the fuel that has flowed down to the bottom wall of the combustion tube (1) is in a liquid state, the mixing of the fuel and the air is poor, resulting in incomplete combustion and generation of off-flavors, tar and soot. Further, when the combustion starts, the fuel accumulated on the bottom wall is vaporized at a time, so that the combustion is not stabilized, resulting in vibration combustion or abnormal noise. In addition, there was a concern that the body and the ignition heater would be overheated and damaged.

る。(E) Function The liquid fuel ejected from the fuel supply pipe into the rotary cylinder is transmitted to the rotary cylinder, and is scattered into the vaporizing cylinder from a small gap between the rotary cylinder and the blower pipe due to the centrifugal force of the rotary cylinder. The fuel is atomized, and the atomized fuel is mixed with the air discharged from the blower tube and flowing out of a small gap between the rotary cylinder and the blower tube. At this time, when the ignition device provided between the rotary cylinder and the vaporization cylinder is operated, the atomized fuel in the vaporization chamber is ignited,
Combustion with raw fuel is started in the vaporization chamber. When the vaporizing cylinder is heated sufficiently by receiving the heat of combustion from the raw fuel, the atomized fuel scattered and atomized from the gap between the rotating cylinder and the air pipe is quickly vaporized in the vaporizing chamber. . Then, the vaporized fuel in the vaporization chamber flows out from the lower opening of the vaporization cylinder and rises between the peripheral wall of the combustion cylinder and the vaporization cylinder while being mixed with the air discharged from the air hole in the bottom wall of the combustion cylinder. The air is further supplied from the air holes in the peripheral wall of the combustion cylinder, and gasification combustion is performed.

However, unlike the conventional case, there is no concern that liquid fuel will accumulate on the bottom wall of the combustion cylinder, and the mixing state of atomized fuel and air is also good, preventing incomplete combustion and immediately starting live combustion after ignition. It is possible to shift to gasification combustion. In addition, the combustion cylinder is cooled by the rising air from the air hole at the peripheral edge of the bottom wall of the combustion cylinder, and the rotating cylinder and the fuel supply pipe are also cooled by the airflow from the blower pipe. And the durability is improved. Furthermore, since the vaporizing cylinder has no flame hole and is a non-perforated bottomed cylinder, the flame is widely dispersed and shortened.

When the motor (23) is operated, the blower fan (21) and the rotary cylinder (17) rotate at high speed, and outside air is introduced into the air chamber (12) through the intake cylinder (22). The air that has entered the air chamber (12) is supplied into the combustion tube (10) through the blower pipe (18) and the air holes (13) and (14). On the other hand, when liquid fuel such as kerosene is ejected from the fuel supply pipe (19), the liquid fuel hits the upper wall of the rotary cylinder (17) and moves outward by centrifugal force.
It descends along the inner surface of the peripheral wall of the rotating cylinder (17). Rotating cylinder (1
Since a small gap (D) is formed between the air cylinder (7) and the blower pipe (18), the liquid fuel that has descended along the inner surface of the peripheral wall of the rotary cylinder (17) is subjected to the centrifugal force of the rotary cylinder (17). The gas is scattered from the gap (D) between the rotary cylinder (17) and the air pipe (18) into the vaporization chamber (15) inside the vaporization cylinder (16) and is atomized. Rotating cylinder (17) discharged from 18)
And the air flowing out of the gap (D) between the air pipe and the blower pipe (18). At this time, when the ignition plug (20) is operated, the atomized fuel in the vaporization chamber (15) is ignited, and the vaporization chamber (1) is ignited.
Within 5), combustion with raw fuel starts.

The vaporized fuel flowing out of the vaporization chamber (15) moves to the upper part of the combustion cylinder (10) while being mixed with air discharged from the air holes (14) of the combustion cylinder bottom wall (10b). The air is further supplied from the air hole (13) of the peripheral wall (10a), and gasification and combustion are performed.

燃焼音を低減させることが可能となる。After the start of combustion, the fuel is quickly vaporized using the combustion heat, and the mixture of the vaporized fuel and air is also sufficiently performed, so that it is possible to shift to stable gasification combustion,
Combustion noise can be reduced.
燃焼筒の底壁周縁部の空気孔からの上昇空気で燃焼筒
を冷却できるとともに、回転筒や燃料供給管も送風管か
らの空気流で冷却できるので、これら各部材の過熱が防
止され、耐久性が向上する。The combustion cylinder can be cooled by the rising air from the air hole at the peripheral edge of the bottom wall of the combustion cylinder, and the rotating cylinder and fuel supply pipe can also be cooled by the airflow from the blower pipe. The performance is improved.
気化筒は炎孔が無く、無孔有底筒状であるから、火炎
が広範囲に分散されて短くなり、燃焼室を小形にでき、
装置を軽量にして安価に提供できる。Since the vaporization cylinder has no flame hole and is a non-perforated bottomed cylinder, the flame is widely dispersed and shortened, and the combustion chamber can be reduced in size.
The device can be provided in a lightweight and inexpensive manner.
