Abstract

PURPOSE:To reduce an exhausted amount of hydrocarbon and foul odor at the time of fire extinction by installing a fuel condenser at the first half of an exhaust port in a fixed tank, while an air suck-in device at its second half and a foul odor suck-in part are placed after the air suck-in device. CONSTITUTION:A fuel condenser 13 at the first half of an exhaust port in a fixed tank 5, an air suck-in device 17 at its second half and a suck-in part composed of an elastic suck-in bag 20 and its protective vessel 21 are provided. The most part of fuel vapor is converted into liquid by the condenser 13 and foul odor component being not condensed is stored in the elastic bag temporarily and then foul odor component is returned back to the fixed tank 5 by a suck-in fan which is rotated reversely for a specific time. Therefore, fuel vapor and foul odor are not discharged completely outside the burner.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to oil burners such as oil stoves and oil stoves.

One of the biggest problems with conventional oil combustors is their odor. In recent years, products have been developed that emit almost no odor when burning or igniting, but the odor when extinguished is now worse than before due to the adoption of an instant extinguishing method. Therefore, as shown in Figure 5 (Japanese Unexamined Patent Publication No. 56-16028), the idea was to suck the fuel vapor through the suction box 1 with the suction device 2 to prevent it from touching the combustion tube 3 and causing an irritating odor. This is the way to do it. With this method, after the wick 4 is lowered to extinguish the fire, the fuel vapor is sucked into the fixed tank 5 and does not go to the combustion tube 3, so that aldehydes with pungent odors are not discharged. .

Problems to be Solved by the Invention However, although the irritating odor is reduced in the above-mentioned purchasing method, it is difficult to completely eliminate the odor.

Means for Solving the Problems: In order to solve the problems, the present invention provides a fuel condenser upstream of the discharge port of a fixed tank, and a suction section consisting of an air suction device, an elastic suction bag, and a protective container downstream. The composition was regrettable.

Effect With the above configuration, most of the fuel vapor becomes liquid in the condenser and is returned to the tank, and the odor components that are not condensed are accumulated in the elastic suction bag, and then the suction fan is rotated in reverse for a certain period of time to remove the odor components. Fuel vapor and odor components discharged outside the combustor are completely eliminated by returning them to the fixed tank.

Example Examples are shown below.

(Example 1) An example of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which a combustion tube 7 is composed of an inner flame tube 7a having many small holes, an outer flame tube 7b, and an outer tube 7c made of a transparent material such as glass. It is installed on a core guide tube 8 fixed to a fixed tank 5 and a core outer tube 9 surrounding it. Reference numeral 10 denotes a lamp wick, which moves up and down between the wick guide tube 8 and the outer core tube 9. During combustion, it protrudes into the combustion tube 7 and serves as a fuel supply means from the fixed tank 5, and extends from the wick guide tube 8 to the core outer tube 9. When lowered, fuel supply is stopped and the fire is extinguished.

Reference numeral 11 is an oil supply tank, and the oil level in the fixed tank 5 is always kept constant. 12 is a discharge port provided in the fixed tank 5, and 13 is a fuel condenser provided upstream of the discharge port. As shown in Fig. 2, the condenser in this embodiment has 16 condensing plates each having a vent hole 15 with a diameter of 1 am installed in a stepped manner inside a stainless steel cylindrical container 14 with a diameter of 5 cm and a depth of 5 am. It is. Reference numeral 17 is an air suction device installed after the exhaust port 12. When the motor and fan 19 are turned off, the wick 10 is lowered, and at the same time as extinguishing, the air suction device 17 is operated for about 1 minute, and the fuel vapor evaporated from the wick 10 is transferred to a fixed tank. Most of the fuel is condensed in the fuel condenser 1a, and the remaining odor components are transferred to the elastic suction bag 20 in the subsequent stage.
and a protective container 21 into a suction section 22 . After about 1 minute of suction, the fan 19 is reversely rotated and the suction part 22 is turned on for about 30 seconds.
By returning the odor components inside into the fixed tank 5, discharge of the odor components to the outside of the combustor is prevented. The suction part 22 in this embodiment is made of polyethylene with a thickness of 5 microns and processed into a bellows shape, with a diameter of 4 cm and a height of 1 cm, as shown in the cross-sectional view of FIG.
It consists of a suction bag 20 of 0 cm, body (it 12 Bml) and a stainless steel protective container 21 having an air vent 23.

r) was extinguished in a box with a size of I
There is almost no odor when the fire is extinguished.

Further, the fuel condenser 13 is connected to a fixed tank 5 in front of the discharge port 12.
Since the air suction part 17 and the elastic suction bag 20 are provided inside the fuel tank, the air suction part 17 and the elastic suction bag 20 are less likely to get wet with fuel even after repeated use.

(Example 2) The number of cells was 60f in a cylindrical container with the same shape and dimensions as Example 1.
151/inch, 1.5 mm thick condenser plate made of foamed metal filter, a condenser equipped with five condensing plates made of filter, a suction bag made of polypropylene having the same shape and dimensions as in Example 1, and a protective container made of stainless steel. Manufactured a kerosene stove with a division. FIG. 4 shows the configuration of the condenser in this embodiment. In the figure, 24 is a porous condensing plate with communicating holes made of a foamed metal filter. Two minutes after extinguishing the kerosene stove of this example (burning amount: 2000 Kcal!/Hr) under the same conditions as Example 1, the hydrocarbon concentration was approximately 2p.
With PM, there is almost no odor when extinguishing a fire. Further, since the fuel condenser 13 is provided in the fixed tank 5 before the discharge port 12, the air suction part 17 and the elastic suction bag 20 are less likely to get wet with fuel even if used repeatedly.

As described above, the present invention provides a fuel condenser in front of the discharge port of a fixed tank, an air suction device in the rear stage, and a suction unit consisting of an elastic suction bag and a protective container in the rear stage of the same device. To provide an oil combustor that emits less hydrocarbons, has less odor during extinguishing, and has less wetting of an air suction part and an elastic suction bag by fuel.
