To refuel the cartridge tank 45, the cartridge tank 45 is taken out from the main body case 41, fuel is injected into the cartridge tank 45 from the mouthpiece portion 48 of the cartridge tank 45, and the fuel is supplied to the cartridge tank 45.
After confirming that the cap 47 has been supplied to, the cap 47 is fastened to the screw part of the base part 48, turned upside down so that the cap 47 part is turned down, inserted again into the main body case 41, and attached to the upper surface of the fixed tank 44. The cap 47 is inserted into the receiving member 49 provided and placed on the fixed tank 44.

The valve in the cap portion of the cartridge tank 45 is opened by the pin 50 at the center of the receiving member 49, and the fuel in the cartridge tank 45 flows into the fixed tank 44. When the oil level of the fixed tank 44 rises to the valve position of the cap 47, the outflow of fuel from the cartridge tank 45 stops. When the fuel in the fixed tank 44 is supplied to the combustion section 42 by the oil feed pump 43, the oil level in the fixed tank 44 lowers,
Air is supplied from the valve portion of the cap 47 to the cartridge tank 45.
The fuel flows into the inside, and the fuel flows out by that amount, and the fuel in the cartridge tank 44 is supplied so as to keep the oil level of the fixed tank 44 constant.

[0005]

In the above-mentioned conventional petroleum combustion apparatus, in order to supply fuel to the cartridge tank 45, the cartridge tank 45 is pulled out from the main body case 41,
It is necessary to turn the cartridge tank 45 upside down in order to turn the cap 47 upward, and it is also necessary to turn the cartridge tank 45 upside down again to close the cap 47 and insert it into the main body case 41 after fuel supply. Yes, it was troublesome to handle.

Further, the cap 47 is tightened with the base part and the screw. When the cap 47 is not tightened sufficiently, the cap 47 comes off when the cartridge tank 45 is turned over, and the fuel flows out. .

Particularly in an aging society in recent years, the force for tightening the screw is reduced due to the decrease in grip strength, and an urgent improvement is desired. Further, when fuel is supplied to the fixed tank 44, the oil level rises up to the valve portion of the cap 47, and the cartridge tank 45 maintains the constant oil level by the replacement of air.
In order to supply the internal fuel, the outer surface of the cap 47 and the valve portion are always wet with the fuel, and when the cap 47 is removed to refuel the cartridge tank 45, the fuel adheres to the hand and smells. It had the problem of becoming dirty.

It is a box-shaped duct for placing the propeller fan 4 of the main body case 1 in communication with the warm air outlet.

The upper part of the cartridge tank 2 has a fuel filler port 1
8 and an oil filler port 18 which are fitted with the fuel filler port 18, and an electromagnetic induction valve 20 on the lower surface. The electromagnetic induction valve 20 is a valve column 2 mounted inside a vertically movable iron core 21.
2 and a spring 23 that pushes up the valve portion of the valve column 22 in the closing direction, and a filter 24 is attached to the upper portion. The electromagnetic induction valve 20 has a flange portion 20a on the outer periphery and is attached to a burring portion on the bottom surface of the cartridge tank 2 via a seal ring 25. 26 is a cartridge tank leg, and 27 is a cartridge tank handle. On the upper surface of the fixed tank 5 facing the electromagnetic induction valve 20 on the bottom surface of the cartridge tank 2, a hollow cylindrical magnet generator 28 having electric wires wound in a coil shape is attached by a burring portion 5a on the upper surface of the fixed tank 5. The hollow upper surface of the magnetic generator 28 is a tapered portion 28a, and the outer circumference is covered with a metal cylinder 29. The magnetic generator 28 is connected to a drive circuit (not shown) via the float switch 9.

Next, the operation and action will be described with reference to FIGS. When the operation switch 30 is turned on, the heater 11a of the carburetor 11 is energized and the temperature of the carburetor 11 rises to reach a predetermined temperature. When the oil feed pump 10 is driven, the solenoid 13 provided below the jet port 12 opens the nozzle. . Oil pump 10
The fuel sent from is vaporized in the vaporizer 11 and is ejected from the nozzle. The igniter 31 provided in the vicinity of the burner head 15 is discharged, and the gas ejected from the nozzle is ejected and ignited from the side small holes of the burner head 15 to start combustion. At the same time, the propeller fan 4 provided on the back surface of the main body case 1 rotates, and hot air is blown from the hot air outlet on the front surface to heat the inside of the room.

On the other hand, when the cartridge tank 2 is attached to the main body case 1, the fuel in the cartridge tank 2 is float switch 9 when the liquid level in the fixed tank 5 is low.

[0027]

As is apparent from the above description, according to the present invention, the following effects can be obtained.

Since oil is supplied from the movable cartridge tank to the fixed tank by the electromagnetic induction valve at the bottom of the cartridge tank, the oil inlet of the cartridge tank can be provided on the upper surface. Therefore, it is not necessary to turn over the tank when refueling, the fuel filler cap does not get wet with fuel, the fuel does not adhere to the hand, and the oil does not spill even if the filler cap is loose. Further, since oil supply from the cartridge tank to the fixed tank is performed by the oil amount detection means of the fixed tank, the oil level of the fixed tank can be controlled within a certain range. Therefore, the suction height of the oil feed pump that supplies the fuel to the combustion section is constant, and a stable flow rate can be secured.

The electromagnetic induction valve of the cartridge tank and the magnetic generator of the fixed tank are configured to open and close by a magnetic force when the cartridge tank is placed on the fixed tank. In the unlikely event that the main body falls, the cartridge tank slides upward, which separates the magnetic generator from the electromagnetic induction valve and the magnetic force ceases to work, so the electromagnetic induction valve closes instantly and oil drops from the valve part Prevents pottery from falling off.

Further, by providing the controller with a timer circuit for stopping the energization of the magnetic generator after a lapse of a certain time from the conduction signal of the oil amount detecting means, the float of the float switch of the oil amount detecting means is caught on the way. Even if the contact of the float switch is not opened, the magnetic induction of the magnetic generator can be turned off and the electromagnetic induction valve can be closed before the fuel overflows from the upper surface of the fixed tank, so that the fuel does not spill on the main body side.

Further, a major problem of the construction which brings out the effect of the present invention by incorporating an electric pump or an electromagnet in the cartridge tank is to electrically connect the movable cartridge tank side and the main body case side. There is. Dust, dust, and an insulating film such as an oxide film adhered to the connection contact part, causing a conduction failure, and the electric pump and the solenoid valve had a drawback that they could not operate. In the present invention, a magnetic generator is provided on the upper surface of the fixed tank on the main body case side, and the electromagnetic induction valve of the cartridge tank is connected by magnetic force, so that there is no electrical connection contact. Therefore, a defective operation due to dust and dust does not occur, and a highly reliable device can be provided.
