Abstract

PURPOSE:To shorten a time when kerosene is burnt out, in the title burner in which a wick can be vertically moved. CONSTITUTION:A suction means 18 for reducing a bad odor occurring at the time when fire is extinguished is provided in an oil tank 11 having a vertically movable wick 15. This suction means 18 is formed so as to be reversible and to be reversely driven when an oil-burning out switch is turned on. When kerosene is burnt out, therefore, air is sent to the part of the wick 15 through the suction means 18 and the amount of vaporization out of the wick 15, i.e., the amount of burning, is increased and thus burning-out of the kerosene is completed in a short time, if the oil-burning out switch is turned on.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper and lower core type oil combustor.

[0002]

2. Description of the Related Art Generally, an oil combustor of an up-and-down type is equipped with a wick 2 for sucking and vaporizing oil in an oil tank 1 as shown in FIG. 3, and the wick 2 is moved up and down to burn and extinguish. It is like this. At the end of the season or the like, the oil in the cartridge tank 3 for supplying the oil to the oil tank 1 is emptied and the oil in the oil tank 1 is burned to the air.

[0003]

However, in the above-described conventional petroleum combustor, the oil in the wick 2 is only vaporized and burned by the combustion heat vaporized and burned from the wick 2 (hereinafter referred to as self-combustion heat). It took a long time to burn the oil in the oil tank 1 to burn it out.

The present invention is intended to solve such a problem, and it is possible to utilize the suction means for reducing fire extinguishing odor provided in this type of petroleum combustor so that it can be baked in a short time. It was intended.

[0005]

In order to achieve the above object, the present invention comprises a suction means for reducing the extinguishing odor, which is reversible, and at the time of idle baking, the suction means is reversed so that the wick is vaporized from the oil tank. It is configured to send air toward.

[0006]

According to the present invention, since the burning oil is vaporized and burned not only by the self-combustion heat but also by the air flow sent from the suction means during the air-burning, the combustion amount is only the self-combustion heat. Compared with the case, it will be considerably larger, and the firing will be completed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. 1 and 2, 11 is an oil tank, 12 is a lead guide cylinder standing on the oil tank 11, and 13 is a lead fixed on the oil tank 11. Outer cylinder,
Reference numeral 14 is a core gap formed by the core guide tube 12 and the core outer cylinder 13, and 15 is a core provided in the core gap 14. Batter 1
The tip of the 3'is properly exposed above the 3 '. Reference numeral 17 denotes a combustion cylinder, which is placed on the inner fire tray 12 'and the outer fire tray 13', and is configured to perform mixing and combustion inside thereof. Reference numeral 18 denotes a suction means fixed on the oil tank 11 for sucking and discharging the air in the oil tank 11 from a suction port 19 of the oil tank 11. The structure will be described below. A fan case that covers the upper part 19 forms a passage 22 that connects the inside of the oil tank 11 and the atmosphere 21. Reference numeral 23 is a fan provided in the middle of the passage 22 and capable of rotating in the forward and reverse directions, and is driven by a motor 24 attached to the fan case 20.

FIG. 2 shows a drive circuit of the motor 24, and 25 and 26 are switches connected to a power supply circuit to the motor 24, and one switch 25 is provided near a core up-and-down mechanism (not shown). In addition, when the core 15 is lowered, it is switched to the normally open contact 25a side. The other switch 26, which is turned on at the time of baking, is provided at an appropriate position on the front surface of the instrument body. That is, the switch 25
Switches to the normally open terminal 25a side when the core 15 descends, turns on the transistor 27, and then the transistor 2
8, 29 and 30, 31 are turned on, and while the charging voltage of the capacitor 32 is turning 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. There is. On the other hand, one of the above switches (hereinafter referred to as an "air-burning switch") 26 is O
When N, the transistor 33 is turned on, and then the transistors 34, 35 and 36, 37 are turned on, and the dry battery 3
Electricity is supplied from 0 to the motor 24. At this time, a voltage reverse to that when the switch 25 is turned on is supplied to reversely rotate the motor, that is, the fan. Further, the rotation speed of the fan can be changed by the variable resistor 38.

In the above construction, when the wick 15 is operated to expose the wick 15 to the inner and outer igniters 12 'and 13' by appropriate size and ignite, the wick 15 is burned in the combustion cylinder 17 to collect heat. Become. When the core up / down mechanism is operated, the core 15 moves to the core gap 1
Rapidly descend to a prescribed depth within 4 and immerse and extinguish 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. .. As a result, 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 a negative pressure, and the air flows (is sucked) from the core gap 14, and the petroleum 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 one minute, for example, while the transistor 27 continues to be turned on by the charging voltage of the capacitor 32.

On the other hand, when air baking is performed, the core 15 is raised to start combustion, and then the air 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 to supply electric power 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 a voltage reverse to that at the time of switching to 5a is supplied and the fan 23 rotates in the reverse direction, 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 are greatly increased as compared with the case of only the self-combustion heat, so that the amount of combustion is greatly expanded. Therefore, the oil in the oil tank 11 will burn in a short time.

[0011]

As is apparent from the above description of the embodiments, according to the present invention, it is possible to prevent the generation of an irritating odor at the time of extinguishing the fire by the suction means, and to finish the air baking in a short time during the air baking. You can
