Abstract

PURPOSE:To prevent unburned gas from exhausting out of the titled device by a method wherein an unburned gas at the extinction of the device is burnt out by a fixed time electrifying for an igniting heater after the extinction of the device. CONSTITUTION:At an operation of extinction by lowering of a wick 3, an unburned gas is collected nearby an igniting heater 13 with a cutout 12a of a partition plate 12, simultaneously a switch 15 and a thermostat 16 are closed, then the igniting heater 13 is electrified. Consequently, large quantity of the unburned gas produced at the extinction can be burnt out effectively, thus the exhausting of the unburned gas from a device can be prevented. After a certain time, an atmospheric temperature nearby the thermostat 16 is lowered, then the thermostat 16 is opened, the electrifying of the igniting heater 13 is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a wick-type oil-burning device such as a porta-pull oil stove.

Structure of conventional examples and their problems Conventional wick-type oil combustion devices, such as portaple oil stoves, have a wick 3 that can move up and down to suck up fuel 2 from a tank 1, and a wick that can be moved up and down. The core inner/outer cylinders 4, 5 are guided freely, the inner/outer flame cylinders 6, 7 having a plurality of air holes are placed on the upper end of the core/outer cylinders 4, 6, and the inner/outer flame cylinders 6, 7 are arranged to surround these. It consists of an outer cylinder 8 and an ignition heater 9 that starts ignition. In combustion, when the ignition heater 9 is energized with the wick 3 facing the combustion chamber A between the inner and outer flame tubes, the heated wick 3 sucks up the fuel 2.
vaporizes, ignites, and starts combustion.

This combustion takes place in the pores of the inner and outer flame tubes 6 and 7 in the combustion chamber A, and the heat from the flame vaporizes the fuel and supplies air by drafting the combustion gas, leading to pore combustion. Then, depending on the stomatal combustion, the amount of vaporization is kept constant and combustion continues.

If the wick 3 is lowered and extinguished in this condition, a large amount of unburned gas will be generated, and since the temperature at the top of the wick 3 will only drop steadily, vaporization will continue, and a large amount of unburned gas will be generated in addition to the above. However, this rises due to the draft, and part of it goes outside the F-sized machine, and part of the casing is thermally decomposed as it passes between the high-temperature inner and outer flame tubes 6 and 7, becoming aldehyde, etc., and goes out of the machine. These unburned gases are harmful and irritating, so
This caused discomfort to the user. Also, in order to reduce unburned gas as much as possible, it has been considered to close the space above the burning end of the lamp wick 3 with a partition plate 10 in conjunction with the vertical movement of the lamp wick 3, as shown in Figures 2 and 3. However, the problem remained that it was difficult to achieve a complete seal, and that unburned gas could leak through the gaps and be discharged outside the aircraft.

OBJECTS OF THE INVENTION The present invention was made in view of the above-mentioned problems, and an object of the present invention is to effectively burn out unburned gas generated during extinguishing a fire.

Structure of the Invention In order to achieve the above object, the present invention is linked to the vertical movement of the lamp wick,
A closing means is provided to close off the space above the wick when extinguishing the lamp, and a notch is provided in the closing means at a position corresponding to the ignition heater, so that the unburnt gas generated from the wick when extinguishing is passed through the notch to the ignition heater. At the same time as the discharge to the vicinity, the ignition heater is energized for a certain period of time to burn the unburned gas, which effectively burns out the unburned gas during extinguishing and prevents a large amount of unburned gas from being discharged outside the machine.

Description of examples An example of this will be described below with reference to FIGS. 4 to Y.

Reference numeral 3 denotes a vertically movable lamp wick that sucks up fuel 2 from the tank 1. This lamp wick 3 is guided by a wick inner/outer cylinder 4, which guides the vertically movable lamp wick.
It is arranged between 5. In addition, a burner section is formed by the inner and outer flame tubes 8 and 9 having a plurality of pores 8a+9ai placed on the upper end fire pans 6 and 7 of the inner and outer core tubes 4 and 6, and the outer tube 1o disposed so as to surround these. A combustion chamber 11 is formed between the inner and outer flame tubes 8 and 9. Reference numeral 12 denotes a partition plate which moves up and down in the combustion chamber 11 in conjunction with the up and down movement of the lamp wick 3, and is arranged at a certain distance above the tip of the lamp wick 3, and has a notch 12N at a position corresponding to the ignition heater 13. There are three wicks when extinguishing a fire.
At the same time as it descends, the inner core and outer cylinder 4 and 5 are chanted.

Next, the circuit will be explained. The switch 16 is normally closed, but it opens when the wick 3 is raised to cause combustion. Then, with wick 3 raised, ignition switch 1
4 is held down for a certain period of time, the ignition heater 13 is energized during that time, vaporizes and ignites the fuel 2 contained in the lamp wick 3, and starts combustion.

As combustion becomes more stable, the atmospheric temperature in the burner increases,
The mostat 16 provided near the burner portion closes. When such a situation occurs, if you lower the wick 3 to extinguish the fire, switch 16. Since the thermostat 16 is closed, the ignition heater 13 is energized. Then, as time passes, the ambient temperature near the thermostat 16 decreases, the thermostat 16 opens, and the energization of the ignition heater 13 ends.

In the above configuration, combustion is carried out by sucking up all of the fuel 2 from the tank 1 by capillary action, raising the oil-impregnated lamp wick 3 upwards as shown in Fig. 4, and applying electricity to the ignition heater 13 while facing the combustion M11. Fuel 2 vaporizes and gradually ignites to start combustion. Combustion takes place in the pores Ba and ga of the inner and outer flame tubes 8 and 9 in the combustion chamber 11, and the heat from the flame vaporizes the fuel and supplies air by drafting the combustion gas, which is fed back to the pore combustion. Ru. Depending on the stomatal combustion, a constant amount of vaporization is maintained and combustion continues.

In this state, when the fire extinguisher is operated by lowering the lamp wick 3 shown in FIG. 6, the unburnt waste is collected near the ignition heater 13 by the notch 12a of the partition plate 12, and at the same time, the ignition heater 13 is energized. Therefore, the large amount of unburned gas generated when extinguishing a fire can be effectively burnt out, and almost no unburned gas is discharged outside the machine, causing no discomfort to the user. There is an effect.

Effects of the Invention According to the present invention, a large amount of unburned gas generated when extinguishing a fire is effectively burned out, and a large amount of unburned gas is not discharged outside the machine, causing no discomfort to the user. There is an effect.
