This water plasma has a high temperature of at least several thousand degrees Celsius, and can completely burn the kerosene. Then, the kerosene is supplied to the combustion chamber 23 by the fuel supply device 10, so that the kerosene is burned by the water plasma generated by the plasma torch 24. Hereinafter, the configuration and operation of the plasma torch 24 will be described in detail.

FIG. 4 is a schematic structural view of the plasma torch 24. This plasma torch 24 includes a plasma torch main body 241 having a discharge chamber 251 and a working fluid container 24.
6 is provided. The main body 241 has an anode 242 having a discharge port formed thereon, and a rod-shaped cathode 244 coaxial with the discharge port. This cathode 244 is used as a holder 243
It is fixed to. The holder 243 is surrounded by an electrically insulating tube 252, and the electrically insulating tube 252 is further surrounded by a thermally conductive tube 253.
The main body 241 is formed of a ring 24 made of a heat conductive material.
9 The ring 249 contacts the anode 242 and has a passage 250 to the discharge chamber 251 formed tangentially at a contact portion with the anode 242.

The container 246 is connected to the main body 241 via the sleeve 245 on the main body 241 side, and the inside thereof is filled with a moisture absorbing material 247. As the moisture absorbing material 247, for example, kaolin wool or glass wool can be used.

The gap between the main body 241 and the container 246 is
It is filled with a porous heat conductive material 248. The porous heat conductive material 248 is connected to the ring 249 on the main body 241 side.
And the moisture absorbing material 2 on the container 246 side.
47. As the porous heat conductive material 248, a sintered copper shot, a copper chip, or the like can be used.

The cathode holder 243, the electrically insulating tube 252, and the thermally conductive tube 253 extend to the rear end side through the porous thermally conductive material 248 and the moisture absorbing material 247. The rear ends of the tubes 252 and 253 are fixed to the structure 261. The cathode holder 243 is movable in the axial direction in the electrically insulating tube 252, and a button 256 is attached to a rear end thereof. The button 256 has its distal end exposed through the center hole of the lid 254 attached to the structure 262 and exposed to the outside.
60 are arranged so as to abut the inner peripheral edge of the hole. The spring 255 urges the rear end side. A voltage from an external power supply (not shown) can be applied to the anode 244 and the cathode 244.

Water as a working fluid is supplied into the vessel 246 of the plasma torch 24 from the water tank 25 through a water supply pipe 26 and a working fluid replenishing hole 258. The material 247 contains water. When the plasma torch is started in this state, voltage application to the anode 242 and the like starts. Then, when the button 256 is pressed, the cathode holder 243 moves, and the cathode 244 at the tip thereof contacts the anode 242. Then, the pressing of the button 256 stops. When the pushing stops, the spring 255

It passes through the tangent passage 250 of FIG. 9 and enters the discharge chamber 251. Here, the water vapor is turned into plasma. Then, it is blown out through a hole in the central axis of the anode 242. When the water vapor passes through the passage 250, a spiral propulsion is obtained by the above-described circumferential inclination. This propulsion force is inherited even if it is turned into plasma, and further stabilizes the arc and stabilizes the plasma blown out from the hole in the central axis of the anode 242. Thereby, the arc column is stabilized, and at the same time, the anode 242 and the cathode 244 are cooled.

In this plasma torch, about 70 ml of water is consumed when continuously operated for 25 minutes at an input power of 1 KW.

In order to generate the water plasma, power of about 700 W is required. However, the plasma and kerosene fuels have a standard output energy of 1 to 5
The same effect can be obtained even when the ratio is set to, for example, about 1 to 10, so that the fuel efficiency can be made substantially the same as that of a kerosene stove.

FIG. 5 is a timing chart showing the timing of the generation of the plasma and the burning of the kerosene of the petroleum fan heater. The petroleum fan heater according to the present embodiment employs a configuration in which ignition control means for controlling the combustion device 20 so as to burn the kerosene with the water plasma at the time of ignition is provided. In addition, a configuration is employed in which a fire extinguishing control unit that controls the combustion device 20 so as to burn the kerosene with the water plasma at the time of fire extinguishing is provided. Specifically, the timer has a function as the ignition control means and a function as the fire extinguishing control means. Hereinafter, the operation of the petroleum fan heater will be described with reference to the timing chart of FIG. First, the operation at the time of ignition of the heater will be described. In the present petroleum fan heater, the fuel supply device 1 is configured to start generation of the water plasma before ignition of kerosene by the fuel supply device 10 at the time of ignition.
0 and a timing control means for controlling the water plasma generating means. Specifically, the timer has a function as the timing control means.

When the user turns on the power switch, the timer 53 starts measuring time, and after a predetermined time has elapsed, the plasma torch 24 is first activated. Thus, as shown in FIG. 6, a plasma jet for injecting the high-temperature water plasma 24a toward the center of the combustion chamber 23 is formed at time t1. The rise time of the water plasma is as short as about 5 seconds, and becomes high immediately after generation. In this way, the water plasma 24a is generated at the center of the combustion chamber.

When the water plasma is generated,
The motor for driving the fan 34 of the air supply device 30 and the electric pump 1 of the fuel supply device 10 at a predetermined timing based on the time measured by the timer 53.
3 is supplied with electric power from the power supply device 52. And
When the rotation of the fan 34 starts, the external air becomes clean air after various kinds of dust (dust) are removed by the filter 33, and is guided through the air passage 31 to the combustion tube 23 a through the nozzle 21. Flows into the interior. Also,
When the electric pump 13 is operated, the kerosene 11a is atomized by the sprayer 21 through the fuel supply pipe 12, and the air jetted from the nozzle portion directs the kerosene 11a toward the high-temperature plasma in the combustion chamber 23 as shown in FIG. Is injected as shown in FIG. Then, at time t2, the kerosene is ignited by the high-temperature plasma, and the kerosene is burned to form a flame. At the time of this ignition, the kerosene is completely burned by the high-temperature plasma almost simultaneously with the spraying, so that generation of incombustible gas resulting from incomplete combustion can be prevented. Therefore, generation of odor or harmful gas such as CO due to the non-combustible gas can be prevented. 1 and 7 indicate the direction in which the kerosene 11a flows, and the arrows b in FIGS. 6 and 7 indicate the direction of the air flow in the air supply device 30. .

When the kerosene is ignited and a flame is formed, a flame detector (not shown) detects the flame at the beginning of the ignition and inputs it to an abnormality judging unit (not shown). After judging whether or not there is any abnormality, if there is no abnormality, check other safety devices. Thereafter, based on the time measured by the timer 53, at time t3, the generation of the water plasma by the plasma torch 24 is terminated, and electric power is supplied to a motor for driving the fan 44 of the blower 40 so that the fan 44 To work. As a result, external air is taken in from the intake port 41 while being guided by the air guide 42, and after various kinds of dust (dust, dust) are removed by the filter 43, the air becomes clean air. After being guided to the combustion chamber 23 and heated by the heat obtained by the burning of the kerosene, it is sent out from the air outlet 46 as warm air to the outside. In this way, heating is performed. When the control signal is output, the timer 53 stops counting. 6 and 7 indicate the direction of the flow of air in the blower 40. (Hereinafter, margin)

Next, the operation when the heater is extinguished will be described. In the present petroleum fan heater, at the time of fire extinguishing, prior to the termination of the generation of the water plasma, the fuel supply device 10 and the plasma torch 24 are controlled so that the fuel supply by the fuel supply device 10 is terminated.
Is adopted. Specifically, the timer 53 has a function as the second timing control means.

When the user turns off the power switch of the oil fan heater which is heating as described above, the timer 53 starts measuring time, and after a predetermined time has elapsed, the plasma torch 24 is first activated. I do. As a result, a plasma jet heading toward the center of the combustion chamber 23 is formed at time t4, water plasma is generated in the center of the combustion chamber, and the fuel is instantaneously completely burned.

When the water plasma is generated,
Based on the time measured by the timer 53, the power supply device 52 to the electric pump 13 of the fuel supply device 10 is used.
Supply of power from is stopped. Thereby, the supply of fuel is stopped. Then, the kerosene in the combustion chamber 23 is completely burned by the high-temperature plasma, and at time t5, the combustion of the kerosene in the combustion chamber 23 ends, that is, the fire is extinguished. Next, the fan 34 of the air supply device 30
A control signal for stopping the supply of power to the motor that drives the fan is then sent to the power supply unit 52, and a control signal for stopping the supply of power to the motor that drives the fan 44 of the blower 40 is sent to the power supply unit 52, respectively. The operation of the fan 34 of the air supply device 30 and the fan 44 of the blower 40 is stopped. Thus, the supply of air to the combustion chamber 23 and the blowing of warm air to the outside of the device are stopped. Finally, based on the time measured by the timer 53, the generation of water plasma by the plasma torch 24 is terminated at time t6. At this time, the burning of the kerosene in the combustion chamber 23 has already been completed, and the kerosene in the combustion chamber 23 can be completely burned by the high-temperature plasma. Occurrence can be prevented. Note that water plasma is obtained by ionizing water vapor, and is ultimately converted to water, and does not contain components that emit odor or harmful gas. Even if the generation of water plasma ends after the supply of air or kerosene,
No incombustible gas or odor is generated.

As described above, according to the present embodiment, water plasma in which water vapor is ionized by the plasma torch 24 can be generated, and the kerosene can be burned using the water plasma. Since water plasma has a high temperature of at least several thousand degrees Celsius, the kerosene can be completely burned. Thus, when the kerosene is difficult to completely burn, such as during ignition or fire extinguishing, the kerosene can be completely burned using the water plasma as appropriate. Therefore, generation of incombustible gas can be suppressed, and generation of odor and harmful gas can be prevented. The above-mentioned plasma torch 2
No. 4 has a rise time required to generate high-temperature plasma of about 5 seconds, and furthermore, the kerosene is completely supplied even if kerosene is supplied immediately after the high-temperature plasma is generated, that is, injected into the combustion chamber. Can be burned. In the conventional system using a spark plug, the combustion chamber is neglected and filled with fuel, the mixture ratio of fuel and air in the combustion chamber is optimized, and then the ignition plug is used for ignition. It took time. Further, unless the outer screen forming the combustion chamber 23 reaches a certain temperature, stable combustion (hereinafter referred to as stable combustion) is not achieved,
It took time for stable combustion. In the present embodiment, by using high-temperature plasma, combustion can be started even if the mixing ratio is not optimal at the beginning, and the start-up is faster than in a system using a conventional ignition plug. Further, there is also an effect that the temperature of the screen is raised early. In the illustrated apparatus, the combustion can be stably performed if the mixing ratio of the fuel and air in the combustion reaches an optimum state before the plasma generation is stopped.

According to the present embodiment, the timer 53 controls the plasma torch 24 of the combustion device 20 so as to generate the water plasma at the time of ignition, and the combustion device 20 uses the water plasma. Since the kerosene is burned in the combustion chamber 23, the kerosene can be completely burned at the time of ignition. This allows
Generation of incombustible gas at the time of ignition can be prevented. Therefore, generation of odor and harmful gas at the time of ignition can be prevented.

According to the present embodiment, the timer 53 controls the plasma torch 24 of the combustion device 20 so as to generate the water plasma at the time of fire extinguishing, and the combustion device 20 uses the water plasma. Since the kerosene is burned in the combustion chamber 23, the kerosene can be completely burned when the fire is extinguished. This allows
The generation of incombustible gas during fire extinguishing can be prevented. Therefore, generation of odor and harmful gas at the time of fire extinguishing can be prevented.

In particular, according to this embodiment, when the oil fan heater is extinguished by the timer 53, the fuel supply device 1 is turned off prior to the end of the generation of the water plasma.
The electric pump 13 of the fuel supply device 10 and the plasma torch 24 are controlled so that the supply of the fuel by zero is terminated. Thereby, the kerosene in the combustion chamber can be completely and completely burned by the water plasma. Therefore, generation of incombustible gas can be more reliably prevented, and generation of odor and harmful gas can be prevented.

In the above-described embodiment, only the example in which the water plasma is generated only when the oil fan heater is ignited and extinguished has been described. However, the generation of the water plasma generated when the oil fan heater is ignited is stopped. Instead, it may be continuously generated until the fire is extinguished. For example, the timer 53 may be configured to generate power from before the supply of the kerosene to after the supply of the kerosene is stopped. When such continuous generation is performed, combustion can be continued even if the mixing ratio of fuel and air is not always optimal. This makes it possible to promote combustion by supplying a relatively large amount of fuel, thereby increasing the combustion efficiency. Further, not only the heat generated by the combustion of the fuel but also the heat generated by the plasma itself is generated, so that it is possible to obtain hotter hot air without increasing the size of the apparatus. Further, since the plasma is finally reduced to water as described above, no harmful gas or odor is generated from the plasma itself. Therefore, unlike the case where high-temperature hot air is output by increasing the size of the apparatus without using plasma, unnecessary gas emission does not increase. On the other hand, when water plasma is generated only at the time of ignition and at the time of fire extinguishing as in the above-described embodiment, the time required to generate the water plasma is short, so that fuel consumption such as electricity cost required for the generation of the water plasma is reduced. For example, even if the ratio between the energy of the plasma and the energy of the fuel is set to 1: 1,
An increase in fuel efficiency due to generation of plasma can be suppressed.

Further, in the above embodiment, in order to determine the timing of power supply to each unit of the device by the power supply device 52, a device for measuring time and providing a timer 53 for determining the timing of each function is provided. However, in order to determine the timing of power supply to each unit of the device by the power supply device 52, a timer having only a function as a measurement time for measuring time, a CPU for outputting a control signal to each unit of the device, and the like are provided. A control unit may be provided, and each unit in the apparatus may be controlled by the control unit. The control unit may have a function as the ignition control unit, a function as the fire extinguishing control unit, a function as the timing control unit, and a function as the second timing control unit. Good.

In the above embodiment, the present invention is applied to a heater for burning kerosene as fuel. However, the present invention can be applied to a heater for burning fuel other than kerosene. The fuel may be petroleum,
Fuel other than oil may be used.

In the above embodiment, the high-heat generating means for generating high heat using water includes a plasma torch 2 for generating water plasma in which water vapor is ionized.
Although the example provided with 4 has been described, other high heat generating means may be used. For example, a welding machine using water electrolysis can be used.

According to the first to seventh aspects of the present invention, there is an excellent effect that the generation of incombustible gas can be appropriately prevented, and the generation of odor and harmful gas can be prevented. Further, since high heat is generated by using water, there is also an effect that, when the high heat is generated, a gas or a harmful gas that causes odor is not generated.
