Abstract

(57) [Summary] [Purpose] After extinguishing a fire due to lack of oil, refuel to quickly ignite and burn. [Structure] The notification means 15 notifies the user that the oil amount detection sensor 5 is detecting oil shortage. When the operation start operation is performed in this state, the vaporizer 7 is preheated. After the preheating is completed, the ignition standby means 16 prohibits the ignition operation until the notification means 15 is stopped. After refueling, when the oil amount detection sensor 5 detects the presence of oil, the notification means 15 is stopped and the ignition standby means 16 is also stopped. Therefore, the control unit 14 executes the ignition operation, and at this time, the vaporizer 7 is in the preheating completion state, so that the burner 12 quickly ignites and burns.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation control device used for an oil gasification heater such as an oil fan heater.

[0002]

[Prior art]

 2. Description of the Related Art Heretofore, this type of petroleum gasification heater is widely known as a configuration in which fuel oil is heated by a vaporizer and the vaporized gas obtained is burned by a burner. In such a heater, operation may be started at the moment when the oil is depleted, and in this case, the vaporizer notifies the user of the need for refueling through the output of display, voice, etc. The power supply was postponed until the problem disappeared, or the power was supplied despite the fact that the oil was exhausted, and during the subsequent ignition operation, an ignition mistake occurred and forced extinguishing was performed.

[0003]

[Problems to be solved by the device]

 By the way, the vaporizer requires preheating before ignition. Therefore, if the power supply is postponed as described above, preheating will occur after refueling and ignition will not immediately occur, so it was necessary to feel cold for a while. On the other hand, when the sequence leading to forced fire extinguishing is executed, the vaporizer has already warmed up to some extent, so although it ignites and burns in a relatively short time after refueling, a small amount of vaporizer was used during the previous forced extinction. There is a drawback that vaporized gas is emitted and odor is generated. It is an object of the present invention to obtain an operation control device for a petroleum gasification heater that can solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides an oil amount detection sensor provided in an oil receiver on which a cartridge tank is removably mounted, an oil feed pump, and a vaporizer for heating and vaporizing the fuel oil pressure-fed from the oil feed pump. An apparatus, a burner that burns the vaporized gas obtained by the vaporizer, a control unit that controls the operation of the equipment, and a notification unit that notifies that the oil amount detection sensor detects oil shortage, The control unit is configured to include an ignition standby unit that causes the device to stand by in an ignitable state when a driving start operation is performed during the notification of the notification unit.

[0005]

[Action]

According to the above configuration, the vaporizer is preheated with the start of operation when oil runs out.
When preheating is completed, at the same time, the ignition standby means prohibits subsequent ignition operations, and the vaporizer is maintained at a substantially constant high temperature during the operation of the ignition standby means. When refueling is performed and the oil amount detection sensor detects the presence of oil, the ignition standby means releases the prohibition of the ignition operation, and the control section executes the ignition operation, so that the burner quickly ignites and burns. It will be.

[0006]

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes an oil receiver, on which a cartridge tank 3 is detachably mounted via an oil filter 2, and an oil feed pump 4 and a float switch as an oil amount detection sensor for detecting the presence or absence of oil. 5 are arranged. A vaporizer 7 is connected to the oil feed pump 4 via an oil feed pipe 6. The vaporizer 7 is provided with a heater 8 and a temperature detection sensor 9 here, and has a nozzle 11 at one end which is opened and closed by a solenoid 10 (open state in the figure). Reference numeral 12 is a burner, and a frame rod 13 for detecting the presence or absence of flame is arranged above the burner. Reference numeral 14 is a control unit, and 15 is a notifying means for notifying the user that the oil amount detection sensor 5 is detecting oil shortage by lighting a lamp or a buzzer. The control unit 14 has various means for controlling the operation of the equipment therein, as well as an ignition standby means 16 for making the equipment wait in an ignitable state when an operation start operation is performed while the notification means 15 is informing. Is configured.

In the above-described configuration, when the operation start operation is performed, the control unit 14 first operates to supply power to the heater 8. When the temperature detection sensor 9 detects that the vaporizer 7 has risen in temperature and has reached a temperature sufficient to vaporize the fuel oil, the solenoid 10 opens the nozzle 11 and the oil feed pump 4 is started. The fuel oil flowing into the vaporizer 7 is heated and vaporized into vaporized gas, which is ejected to the burner 12 and ignited and burned.

When the fuel oil in the oil pan 1 is consumed to some extent by the combustion, the fuel oil is replenished from the cartridge tank 3 as needed. When the cartridge tank 3 is finally emptied by repeating such replenishment, the float of the float switch 5 descends and turns on, so that the notifying means 15 operates to prompt the user to refuel. When the fuel is not supplied due to the absence of a person in the room, after a short time, the oil feed pump 4 starts to run empty and the fire extinguishes on the way, and the flame rod 13 detects this and extinguishes it forcibly.

After the forced fire extinguishing, for example, when the operation is started the next morning, the notification means 15 prompts the refueling again, so that the user pulls out the cartridge tank 3 to refuel. On the other hand, the vaporizer 7 starts preheating as described above. When preheating is completed during the refueling operation, the ignition standby means 16 operates to prohibit operations necessary for ignition, such as starting the oil feed pump 4 and opening the nozzle 11, while supplying power to the heater 8. By permitting, the vaporization device 7 is maintained at a substantially constant high temperature based on the temperature detected by the temperature detection sensor 9.

When the refueling work is completed and the cartridge tank 3 is reset, the oil pan 1 is refilled with fuel oil, and the float rises to the position indicated by the dotted line, whereby the float switch 5 is turned off. Since the output of the notification means 15 is stopped accordingly, the start prohibition of the oil feed pump 4 by the ignition waiting means 16 is also canceled. Therefore, the control unit 14 executes the ignition operation, but since the vaporizer 7 is already in the preheating completion state, the burner 12 can quickly perform the ignition and combustion.

When refueling is not performed at the start of the operation after the forced fire extinguishing, the power supply to the vaporization device 7 is continued, thereby wasting power. Therefore, preferably, the control unit 14 is provided with a timer for counting the operating time of the ignition standby means 16, and the control unit 14 is configured to execute the fire extinguishing process when the count reaches a predetermined value. good.

[0012]

[Effect of device]

 As described above, in the present invention, the control unit for controlling the operation of the device has a configuration having an ignition standby means for making the device stand by in the ignition state when the operation start operation is performed during the notification of the notification means. Since it is equipped, it is possible to completely prevent the generation of odor due to the ignition operation being performed in the state of running out of oil, and after fire extinguishing due to running out of oil, the excellent effect of quickly igniting and burning by refueling Play.
