It is possible to sequentially burn and control by the programmed control.

FIG. 3 (A) shows an operational flowchart for explaining a process of completely burning the combustion gas remaining in the combustion chamber until the petroleum combustion device is operated and operated normally. When the combustion device starts to operate, the duct cover is shown. If it is not closed by judging whether or not (5) is closed, the duct motor 6 is operated to judge whether the duct cover 5 is closed, and when it is not closed, the duct motor 6 is operated to operate the duct cover. If the duct cover 5 is closed in the first judging step 12 and the first judging step 12 is repeatedly performed to close the 5, the preheating heater 1, the burner motor 2, the ignition controller (3) and the electronic pump 4 are sequentially operated to determine the ignition and to stop operation of the ignition controller 3 during ignition, and the ignition controller (in the sequential operation step 130). 3) When the operation is stopped, drive the duct motor to the duct cover (5) When the second duct cover 5 is opened and the duct cover 5 is not opened, the second determination step 140 is repeated to drive the duct motor 6 so as to open the duct cover 5. When the duct gerber 5 is opened in the second judging step 140, the driving of the duct motor 6 is stopped and controlled in each step of performing the normal operation step 150 of normal operation.

More specifically, the step 101 of determining whether the duct cover 5 is open or closed in the operation of starting the petroleum combustion device 100 is performed, and if the step 101 is opened by determining Go to (102) to send a control signal to the duct motor (6) to close the duct cover (5), go back to step 103 to determine this to perform a continuous operation.

If it is determined that the duct cover 5 is closed, the step 104 of operating the preheater 1 to the temperature at which the oil vaporizer 13 can be vaporized is carried out, and it is determined whether the preheating has been performed to a sufficient temperature. After step 105, if the preheating has not been completed, the preheating heater 1 is operated until the preheating is sufficient, and if the preheating is completed, the gas necessary for combustion is supplied to the vaporizer to mix the vaporized gas and the air. The operation 106 of operating the burner motor 2 is performed.

When the step 106 is performed, the step 107 of operating the ignition controller 3 to generate the spark discharge required for ignition, the electronic pump for injecting the oil required for combustion from the oil tank (not shown) to the carburetor Operation step 108 of (4) is performed.

At this time, the mixed gas is attempted to ignite by the spark discharge by the spark plug 12, and if it is not ignited through the step 109 of determining whether ignition has occurred, the previous step 108 is repeated, and if ignited A step 110 of stopping the operation of the ignition controller 3 is performed.

If the unburned gas is completely burned through the steps up to the stop of the ignition controller 3, the duct cover 5 is opened through the step 111 of operating the duct motor 6 to open the duct cover 5. The determination step 110 of determining is performed.

When the duct cover 5 is not opened, the step 111 is repeated and when it is closed, the duct motor 6 is automatically controlled to enter the normal operation step 114 through the step 113 of stopping the operation of the duct motor 6. .

FIG. 3b is an operation flowchart for explaining a process of completely burning unburned gas remaining in the combustion chamber after extinguishing a petroleum combustion device. When the operation of the combustion device is stopped, the electronic pump 4 and the burner are shown. When the burner motor 22 is stopped in the sequential running stop step 160 of stopping the motor 2 and the sequential stop 160, the duct motor 6 is operated to operate the duct cover 5. Closing and determining whether the duct cover 5 is closed, if not closed, the third judging step 170 of repeatedly driving the duct motor 6 to be closed by continuously driving the duct motor 6, If the duct cover 5 is closed in the third judging step 170, the driving of the duct motor 6 is stopped, the fan motor is operated to cool the combustion chamber 11, and after a predetermined time, the fan motor Perform the driving stop step 180 to automatically stop the driving of (8) Each step is controlled.

In more detail, when the step 200 of extinguishing the petroleum combustion device is performed, the operation of the electronic pump 4 is stopped from the oil tank (not shown) to the vaporizer 13 through the step 201. The petroleum molecules to be supplied are stopped, and the burner motor stop step 202 shuts off the combustion air.

At this time, the step 203 of closing the duct gerber 5 by driving the duct motor 6 to prevent the unburned gas remaining in the combustion chamber 11 from being discharged to the outside is performed. When the duct cover 5 is not closed, the step 203 is repeated, and when the duct cover 5 is closed, the fan is stopped for a predetermined time through the step 205 of stopping the driving of the duct motor 6. The motor 8 is operated to cool the combustion chamber 11 to remove odors of unburned gas, to prevent overheating and to automatically stop the operation of the fan motor 8 to perform step 206. Referring to the effect of the present invention as described above is as follows.

When ignited, the petroleum required for combustion is injected into the vaporizer 13 through the electronic pump 4 from the oil tank (not shown) to the vaporizer 13 preheated by the preheater 1 during combustion. It turns into a suitable gas.

At this time, the vaporized petroleum gas is mixed with the combustion air supplied by the burner motor (2) to form a mixed gas, which is transferred to the burner (9). The mixed gas transferred to the burner 9 is ignited in contact with the spark discharge of the spark plug 12 by the control of the ignition controller 3.

However, until it is ignited, a large amount of unburned mixed gas is already released through the burner 9 due to the lack of mixing ratio with air.

At this time, by closing the duct cover 5 under the control of the microcomputer 10, the unburned mixed gas in the combustion chamber 11 is not discharged to the outside. After ignition, the unburned gas that is not discharged in the combustion chamber 11 is burned together, thereby enabling complete combustion.

At this time, the microcomputer 10 receives a signal by the position switch 7 attached to the duct motor 6 and transmits a control signal to the duct motor 6. The duct motor 6 opens the duct cover 5. The combustion gas, which is opened and completely burned, is discharged out of the device by the blowing air of the fan motor 8. On the contrary, when extinguishing, the electronic pump 4 stops petroleum spraying, the burner motor 2 stops operating under the control of the microcomputer 10, and when the duct cover 5 is closed, unburned gas is released. It is impossible to discharge to the outside in the combustion chamber (11).

Therefore, unburned gas in the combustion chamber is completely burned in the combustion chamber. Thereafter, the fan motor 8 is operated for a predetermined time to cool the inside of the combustion chamber 11 to prevent overheating inside the device.

The present invention thus combustes the uncombusted gas remaining in the combustion chamber until the normal operation by operating the petroleum combustion equipment, and completely removes the gas due to unburned after extinguishing, causing unpleasant leakage to the outside during ignition or ignition. Odor can be prevented in advance, and it can provide a very useful effect to keep the surroundings of oil burning equipment pleasant and clean.
