Further, the diameter of the hollow portion 11' gradually increases from one side to the other side according to the rotational direction of the rotary disk 9.

On the side of the maximum diameter hollow part 11' of the blower case 11 in the direction of the evaporator coil pipe 7, there is an air guide pipe 14 that communicates with the evaporator coil pipe 7.
The air guide pipe 14 communicates with a hollow annular air chamber 15 provided concentrically with the evaporator coil pipe 7.

The operation of the embodiment device having the above configuration will be explained below.

As is well known, the upper surface level of oil in the auxiliary tank 23 is always maintained at a predetermined level by the main oil supply tank 26, pump 25, and overflow pipe 24.

By driving the drive source of the drive pulley 30, the main shaft 1 is rotated, and accordingly, the rotating disk 9, the centrifugal pressure tube 5, the communication tube 6, and the evaporator coil tube 7 are also rotated integrally. In this state, the valve 21 is opened. The oil in the auxiliary tank 23 is connected to the pipe 22 and the oil supply fitting 2.
0, flows into the centrifugal pressure pipe 5 through the oil supply hole 3 of the main shaft 1. The oil flowing into the centrifugal pressure tube 5 is sequentially sent toward the rotating disk 9 by the centrifugal force generated as the centrifugal pressure tube 5 rotates, and then fills the evaporator coil tube 7 via the communication tube 6. By the way, as mentioned above, the centrifugal pressure tube 5 and the evaporator coil tube 7
Since the winding directions are opposite to each other and the pipe diameter, winding diameter, and number of windings are set to be the same, the pressure inside the pipe resulting from the centrifugal force of both is balanced and cancelled, and the pressure from the nozzle 8 is No oil will leak.

In this state, the gas burner 18 is ignited. As a result, the seven turns of the evaporator coil tube near the nozzle 8 are heated, and the oil in the tube begins to vaporize. Oil vaporizes, expands in volume, and tries to spread out. but,
Since the diffusion of the oil is not allowed to proceed to the right in the drawing of the evaporator coil tube 7 filled with oil, the oil is discharged from the nozzle 8 and combustion begins.

On the other hand, when oil is vaporized and consumed by combustion, the pressure inside the evaporator coil tube 7 decreases, and the pressure balance between the centrifugal pressure tube 5 and the evaporator coil tube 7 is broken, and in order to compensate for this, the centrifugal pressure Petroleum in the tube 5 flows toward the evaporator coil tube 7 via the communication tube 6 due to centrifugal force.

On the other hand, when combustion starts, the entire length of the evaporator coil tube 7 is heated by the heat, and the petroleum inside the tube progresses to vaporization, and the entire length is filled with vaporized gas. The tube 6 is sufficiently extended and bent in the radial direction of the original axis at a position separated by the heat insulating disk 13 and the rotating disk 9, and is rotated and is under an air-cooled condition, so that the inside of the tube is under a cooling condition. Since the oil is flowing in the direction of the evaporator coil tube 7, there is no possibility that the vaporized gas will flow back through the communication tube 6 to the centrifugal pressure tube 5.

In this way, the supply of oil to the evaporator coil tube 7 continues smoothly, the supplied oil is completely vaporized within the evaporator coil tube 7, and therefore only the vaporized oil is discharged from the nozzle 8. Combustion continues using only vaporized oil.

Therefore, if the rotational speed of the main shaft 1 that rotates via the continuously variable transmission is changed, the change in the rotational speed of the rotating disk 9, the centrifugal pressure tube 5, and the evaporator coil tube 7 that rotate integrally will change. change. There is a correlation between increasing the rotational speed, increasing centrifugal force, increasing replenishment of oil to the evaporator coil tube 7, and promoting vaporization accordingly.
Furthermore, due to the correlation between an increase in the amount of vaporized oil injected from the nozzle 8 and an increase in the pressure difference between the centrifugal pressure tube 5 and the evaporator coil tube 7, the combustion power increases, and conversely, if the rotation speed is slowed down, the combustion force decreases. becomes.

On the other hand, when the rotary disk 9 rotates, the wind generated by the action of the blades 10 is sent from the small diameter part to the large diameter part in the hollow part 11' of the blower case 11, and the air guide pipe 1
4. The wind blows out from the primary air hole 17 and the secondary air hole 16 through the air chamber 15, and the wind blows out from the primary air hole 17 cools the evaporator coil tube 7, and then becomes the supply air to the combustion section, and becomes the secondary air. The air blowing out from the air holes 16 cools the inside of the combustion cover 29 and then supplements the air supply to the combustion section. Therefore, abnormal temperature rise of the evaporator coil tube 7 is prevented, and the supply air necessary for combustion is sufficient to promote complete combustion. Therefore, as the rotational speed of the rotating disk 9 becomes faster, that is, as the combustion power increases, the amount of air blown from the air blowing case 11 increases, and the amount of air supplied to the combustion section and the evaporator coil tube 7 increase. cooling power increases.

(Function of the invention) The present invention utilizes centrifugal force, and even if the main shaft 1, rotating disk 9, centrifugal pressure tube 5, and evaporator coil tube 7 are rotated before combustion starts, the inside of the centrifugal pressure tube 5 remains When the pressure inside the evaporator coil tube 7 is in a balanced state and no oil leaks from the nozzle 8, combustion starts.
Only vaporized oil is discharged from the nozzle 8 to start combustion, and during combustion, the pressure balance is broken due to oil consumption on the evaporator coil tube 7 side, so the evaporator coil tube 7 is operated to compensate for this. It has the effect of ensuring a lubricated supply of oil to the side and linking the increase in combustion power and the amount of supply. Further, the positional relationship between the evaporator coil tube 7 and the nozzle 8 has the effect of discharging only completely vaporized oil from the nozzle 8 and burning it. Furthermore, the shape and arrangement of the communication pipe 6 have the effect of preventing the backflow of vaporized petroleum in the direction of the centrifugal pressure pipe 5 and preventing the occurrence of hunting, thereby ensuring smooth flow and supply of petroleum. Furthermore, since there is a correlation between the rotational speed of the rotating disk 9 and the combustion power, the amount of air supplied to the combustion section and the cooling power for the evaporator coil tube 7 can be secured in accordance with the rotational speed. The effects of the configuration of the present invention are extremely diverse.

(Other Embodiments) In the above embodiments, when the rotating disk 9 is rotated, the pressure inside the centrifugal pressure tube 5 and the evaporator coil tube 7 caused by centrifugal force is balanced and canceled out.
The respective winding directions were set to be opposite to each other, and the pipe diameter, winding diameter, and number of windings were set to be the same for both.
If the winding directions are reversed and at least the pressure in both tubes is balanced and cancelled, then
The tube diameter, winding diameter, and number of windings may be set differently, and the same effect as that of the embodiment is brought about.

(Effects of the invention) According to the invention, combustion is possible using only vaporized oil, and since there is sufficient air supply, incomplete combustion does not occur, ensuring highly efficient and sanitary combustion. be done. Moreover, the increase/decrease in combustion power and the accompanying amount of air supplied to the combustion section can be automatically controlled in a stepless manner, and the temperature rise in the evaporator coil tube can be automatically suppressed according to the temperature rise. Its practical effect is remarkable.
