DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an up-and-down type petroleum combustor.

[0002]

2. Description of the Related Art In general, an up-and-down type oil combustor is provided with a light core 2 for sucking up oil in an oil tank 1 and vaporizing the oil as shown in FIG. It has become. At the end of the season or the like, the oil in the cartridge tank 3 for supplying the oil into the oil tank 1 is emptied, and the oil in the oil tank 1 is burned completely.

[0003]

However, in the above-mentioned conventional oil combustor, the oil in the light core 2 is only vaporized and burned by the combustion heat (hereinafter referred to as self-combustion heat) vaporized from the light core 2 and burned. The empty baking to burn off the oil in the oil tank 1 took a very long time.

The present invention has been made to solve such a problem, and an object of the present invention is to make it possible to perform an idle burning in a short time by using a suction means for reducing a fire extinguishing odor provided in this kind of oil combustor. It is intended.

[0005]

According to the present invention, in order to achieve the above object, the suction means for reducing the fire extinguishing odor is configured to be rotatable in the normal and reverse directions. It is configured to send air toward

[0006]

According to the present invention, since the oil during combustion is vaporized and burned not only by the self-combustion heat but also by the air flow sent from the suction means at the time of idling, the amount of combustion is limited only by the self-combustion heat. This is considerably larger than in the case, and the baking is completed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 11 denotes an oil tank, 12 denotes a lead guide tube erected on the oil tank 11, and 13 denotes a lead fixed on the oil tank 11. Outer cylinder,
Reference numeral 14 denotes a core gap formed by the core guide cylinder 12 and the core outer cylinder 13, and reference numeral 15 denotes a core provided in the core gap 14. Fire plate 1
The tip is appropriately exposed above 3 '. Reference numeral 17 denotes a combustion tube, which is placed on the inner fire tray 12 'and the outer fire tray 13', and is configured to mix and burn inside. Reference numeral 18 denotes a suction means fixed on the oil tank 11, which sucks and discharges air in the oil tank 11 from a suction port 19 of the oil tank 11. The structure thereof will be described below. A fan case covered on top of 19 forms a passage 22 for communicating the inside of the oil tank 11 with the atmosphere 21. Reference numeral 23 denotes a forward / reverse rotatable fan provided in the middle of the passage 22, and is driven by a motor 24 attached to the fan case 20.

FIG. 2 shows a drive circuit for the motor 24. Reference numerals 25 and 26 denote switches connected to a power supply circuit for the motor 24. One switch 25 is provided near a core lifting mechanism (not shown). When the core 15 is lowered, it is switched to the normally open contact 25a side. The other switch 26 is turned on at the time of idling, and is provided at an appropriate position on the front surface of the appliance body. That is, the switch 25
Is switched to the normally open terminal 25a side when the core 15 descends, turning on the transistor 27, and then turning on the transistor 2
8, 29 and 30, 31 are turned on, and while the charging voltage of the capacitor 32 turns on the transistor 27, electricity is supplied from the dry battery 30 to the motor 24 to operate the motor, that is, the fan 23. I have. On the other hand, one of the switches (hereinafter referred to as an empty burning switch) 26 is
N, the transistor 33 is turned on, and then the transistors 34, 35 and 36, 37 are turned on, and the battery 3
0 to the motor 24. At this time, a reverse voltage is supplied as compared to when the switch 25 is turned on, and the motor, that is, the fan is rotated in the reverse direction. Further, the rotation speed of the fan can be changed by the variable resistor 38.

In the above construction, if the wick 15 is exposed to the appropriate size on the inner fire tray 12 'and the outer fire tray 13' by operating the wick raising / lowering mechanism and ignited, the wick 15 can be burned and heated in the combustion tube 17. Become. Then, when the lead-up / down mechanism is operated, the lead 15 becomes the lead gap 1.
It descends and sinks rapidly to a predetermined depth in 4 and extinguishes the fire. At this time, the switch 25 is switched to the normally open terminal 25a, the transistor 27 is turned on by the charging voltage of the capacitor 32, and then the transistors 28, 29 and 30, 31 are turned on to supply electricity to the motor 24 of the suction means 18. . Thereby, the fan 23 operates to suck and discharge the air in the oil tank 11. As a result, the inside of the oil tank 11 becomes negative pressure, air flows in (sucks) from the core gap 14, and oil vapor is sucked from the core 15 into the oil tank 11 and discharged from the passage 22 to the outside. This operation is continued, for example, for one minute while the transistor 27 is kept ON by the charging voltage of the capacitor 32.

On the other hand, when the baking is performed, the wick 15 is raised to start combustion, and then, when the baking switch 26 is turned on, the transistor 33 is turned on, and then the transistors 34, 35 and 36, 37 are turned on. , Suction means 1
8 is supplied to the motor 24 to operate the fan 23. At this time, the normally open contact 2 of the switch 25 is connected to the motor terminal.
Since the reverse voltage is supplied and the fan 23 rotates in the reverse direction at the time of switching to 5a, outside air is sucked into the oil tank 11 through the passage 22, the fan case 20, and the suction port 19. Then, the air in the oil tank 11 is pushed up to the core gap 14, and the air flows into the combustion cylinder 17. As a result, the amount of vaporization from the wick 15 and the amount of combustion air greatly increase as compared with the case of only the self-combustion heat, so that the amount of combustion greatly increases. Therefore, the oil in the oil tank 11 burns in a short time.

[0011]

As is apparent from the above description of the embodiment, according to the present invention, it is possible to prevent the generation of an irritating odor at the time of fire extinguishing by the suction means, and to terminate the empty baking in a short time at the time of empty baking. Can be.
