As shown in (5), fuel is supplied from the cartridge tank 45 to the tank 44, and the fuel in the tank 44 is supplied by the pump 46 to the vaporizing section 47 maintained at a predetermined temperature or higher during combustion. The fuel is supplied to the vaporization section 4 maintained at a high temperature.
The gas is vaporized in 7 and becomes a fuel gas. The fuel gas is ejected from a nozzle 48, supplied to a burner unit 49, and burned there. Further, in the vicinity of the burner section 49, a flame rod type combustion sensor 51 for applying a voltage between the frame electrode 50 and the burner section 49 inserted in the combustion flame and measuring the amount of flowing current to detect the combustion state. Is arranged. The generated high-temperature combustion exhaust gas is guided upward by a combustion tube 52 disposed so as to cover the periphery of the burner portion 49, and mixed with a room air flow from a blower 54 by a duct 53 covering the combustion tube 52. ,
It is discharged as warm air and used for heating.

いる。A nozzle 48 for ejecting fuel vaporized gas from a vaporizing section 47 is opened and closed by a needle valve provided in a movable section of an electromagnetic solenoid 55. When combustion is stopped, the electromagnetic solenoid 55 is energized for a predetermined time, and the nozzle 48 is energized. The combustion is stopped by preventing the fuel gas from being ejected from the fuel cell.

った。However, in such a conventional hot air heater, if the power supply to the equipment is stopped during the combustion when the outlet of the equipment is disconnected or the power supply to the equipment is stopped for some reason, the air supply to the blower 54 and the pump 46 is stopped. The energization is stopped and the combustion is interrupted. At this time, the vaporized gas of the fuel stored in the vaporizing section 47 kept at a high temperature is discharged from the nozzle 48 without being burned, and goes out of the device as white smoke with a strong odor to be used. There was a problem that caused discomfort and anxiety to the elderly.

に大変な不満をもたらしめていた。[0006] This power outage is usually not likely to occur very often due to the power situation, and it is thought that there is a lot of short time even if it occurs, but it is usually possible that the user accidentally turns off the power of the equipment. It is assumed that it has been removed, and even if the power is immediately restored at that time, the combustion is stopped because the power is turned off once. Even if the user manages the above-mentioned white smoke of the vaporized gas or the like, the user does not stop, and the user is very dissatisfied.

常の臭いを発生する恐れもあった。[0007] When this power failure is repeated, the vaporized gas of the fuel ejected from the nozzle 48 adheres to the surroundings,
There is also a possibility that tarification occurs, the function of the attached portion is reduced, and a constant odor is generated.

こす可能性があった。Furthermore, if the rotation of the blower 54 becomes weak or stops for some reason during combustion, the burner 49
There is a possibility that a part of the wind of the blower 49, which is supplied to the burner and used as the combustion air, is reduced to cause a problem in the combustion of the burner portion 54.

すくなり燃焼は空気不足気味となり乱れ易くなる。This is more likely to occur remarkably as the combustion is weak and the set rotation speed of the blower 54 is lower.
If the rotational speed of the blower 54 is low, the rotational force of the blower 54 is weak, and the load of the blower 54 becomes large due to defects such as scratches and rust of the shaft of the blower 54 itself and dust in the bearing portion. When the combustion amount is low and the combustion amount is small, the combustion is likely to be affected by a decrease in the rotation speed of the blower 54, and the combustion tends to be insufficient and the air becomes turbulent.

切れを生じる課題があった。Here, if the combustion is disturbed, the characteristics of the combustion exhaust gas may be deteriorated, causing odor or generating carbon monoxide. Therefore, the control unit 56 detects the combustion state of the burner unit 49. When the output of the combustion sensor 51 decreases and is maintained at or below a predetermined level for a predetermined time, it is determined that the combustion of the burner unit 49 has caused an abnormality for some reason, and the combustion is stopped. There was a problem of cutting.

の心配もあった。If the above-mentioned predetermined level is lowered in order to prevent premature cutting, or if the preserving time is extended and the direction is set to be late, there is a possibility that the rotation of the blower 54 will be stopped, and the burner section 49 will be stopped. The high-temperature exhaust gas burned in the above flows upward, abnormally increasing the temperature of the upper part of the main unit, burning parts such as the operation unit disposed on the upper part of the main unit, increasing the outer temperature of the upper part of the main unit case, There were also concerns such as fires.

There is a problem that the combustion is disturbed in the same manner as described above even if the gas flows backward to the 49 side.

In order to prevent air from flowing back to the burner due to drafts or to reduce or stop the rotation of the blower for some reason, stop the combustion by increasing the rotation speed of the blower so that the rotation of the blower does not weaken. The second object is to prevent premature disconnection of the burner and to enable safe use for a long period of time, and the third object is to prevent heat from remaining in the burner and equipment.

いほど低減されるようになる。Therefore, when there is a power failure for some reason during combustion, the vaporized fuel gas stored in the vaporizing section 6 kept at a high temperature is discharged from the nozzle hole 11A of the nozzle section 11 without burning. There is a concern that the user may feel uncomfortable or uneasy by emitting white smoke with a strong odor to the outside of the device, which may cause the user to feel uncomfortable or uneasy. The electromagnetic solenoid 13 is operated for a predetermined period of time until the temperature of the nozzle drops to some extent and the fuel in the vaporization section 6 is returned via the return pipe 12, and the nozzle hole 11 A of the nozzle section 11 is closed by the needle valve 14. Therefore, after the return, the vaporized gas is not discharged from the nozzle hole 11A of the nozzle 11 and the above-mentioned discomfort and anxiety of the user can be reduced, and the shorter the time of the power failure, the lower the reduction. Uninaru.

There was also a risk of generating a bad smell, but this is also reduced.

短くできようになる。Further, the blower 21 is also operated for a predetermined time while the temperature of the vaporizing section 6 is high at the time of recovery from the power failure, so that the build-up of the temperature near the burner section 15 due to the interruption of combustion is eliminated.
Since the temperature of the surrounding parts and the exterior temperature of the upper part of the main body case 1 are increased, the user is not worried about burns or impairing the performance of the device, and the temperature of the vaporizing section 6 is quickly lowered. In addition, the operation time of the electromagnetic solenoid 13 can be shortened.

は継続されるようになる。Here, in the case where the rotation of the blower 21 is reduced due to a defect such as a flaw of the shaft of the blower 21 itself, rust or a bite of the bearing portion, the rotation of the blower 21 is usually increased to recover the blower 21. The rotation speed of the blower 21 does not decrease even if the causes such as the scratches and rust of the shaft of the shaft 21 itself and the bite of the bearing portion are removed and the rotation speed is returned to the original rotation speed. According to experiments, it has been confirmed that once the cause of the rotation inhibition is removed, the phenomenon that the rotation speed decreases will not be reproduced, and when the rotation speed of the blower 21 decreases, the rotation speed is temporarily reduced. It is assumed that the rotation speed of the blower 21 is increased to a higher value, the rotation speed is returned to the original rotation speed, and the above-mentioned control is repeated when the rotation speed of the blower 21 decreases again. The rotation will continue.
