Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a wick-type kerosene stove that does not generate black soot, white smoke, bad odor, etc. when it is relit.

[Prior Art] FIG. 2 is a diagram showing the main structure of a conventional kerosene stove.

Kerosene 3 is supplied from a fuel tank 1 to a fuel tank 2.

One end of the wick 4 is immersed in kerosene 3 in the fuel tank 2. The core 4 is covered with a core outer cylinder 5.

When burning, the wick 4 is raised to the vicinity of the burner 6 (the dotted line in the figure). The kerosene that has passed through the wick 4 by capillary action is vaporized and burned in the burner 6 section.

[Problems to be solved by the invention] By the way, recent kerosene stoves are equipped with anti-seismic extinguishing devices to prevent flames and the like. Therefore, even when a slight stimulus such as vibration is applied, the wick retracts and is automatically extinguished.

However, on cold days, we feel the urge to light a fire as soon as it goes out to stay warm.

If you want to relight the fire within three minutes after it has been extinguished, in a conventional wick type kerosene stove, lift the burner 6 a little to blow in fresh air and relight it. This method produces black soot when ignited,
There was a problem with a bad odor. The generation of black soot is caused by the abnormal growth of fire. The bad odor is also caused by the kerosene vaporizing because the core has not yet cooled down.

There is also a wick-type kerosene stove that ignites by energizing the ignition heater without lifting the burner 6. Although such a wick-type kerosene stove does not generate the black soot, the kerosene gas concentration of the kerosene and air mixture increases, making it difficult to ignite. Furthermore, since the wick is not sufficiently cooled, white smoke is produced due to vaporization of kerosene, and a foul odor that hits the nose is produced.

Both problems are caused by the core not being sufficiently cool.

The present invention was made to solve the above-mentioned problems, and the purpose is to provide a wick-type kerosene stove that is easy to relight and does not generate black soot, white smoke, or bad odors. .

[Means for Solving the Problems] In order to solve the above problems, the wick-type kerosene stove according to the present invention connects one end of the pipe containing the circulation pump to the fuel tank, and connects the other end to the wick. A device is provided that is connected to a part of the covering outer cylinder and circulates the kerosene in the fuel tank into the pipe.

[Function] Since the pipe line for supplying kerosene is provided in a part of the core outer cylinder, kerosene can be poured into the core immediately after extinguishing the fire. By injecting kerosene into the core, the temperature of the core can be quickly lowered.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the main structure of the wick type kerosene stove according to this invention.

Kerosene 9 is supplied from the fuel tank 7 to the fuel tank 8.

One end of the wick 10 is immersed in kerosene 9 in a fuel tank 8.

The core 10 is covered with a core outer cylinder 11.

When burning, the wick 10 is raised to the vicinity of the burner 12.

The above configuration is the same as that of a conventional wick-type kerosene stove.

In this embodiment, a conduit including a circulation pump 13 is further provided, one end of which is connected to the fuel tank 9, and the other end connected to a part of the outer cylinder 11. That is, a circulation pump 13, an oil suction pipe 14, a circulation tube 15, and a discharge port 16 are provided.

The oil suction pipe 14 is made of Cu, and one end thereof is connected to the fuel tank 9. The discharge port 16 is provided at a position above the position of the wick 10 when the fire is extinguished and the wick 10 is lowered.
One end of the circulation tube 15 made of Cu is connected to the discharge port 16 . The circulation pump 13 is a spiral pump.

Furthermore, a temperature sensor 17 is provided to measure the temperature of the core outer cylinder 11 portion. The temperature sensor 17 measures the temperature of the outer tube 11 portion. The temperature information is then sent to the built-in computer.

Next, the relighting operation of the wick type kerosene stove according to the present invention will be explained.

Assume that the anti-seismic fire extinguisher works and the fire in the kerosene stove is extinguished. Then, assume that it is necessary to relight the wick 10 while not much time has passed since the fire went out, that is, while the wick 10 has not yet cooled down.

To ignite the kerosene stove, press down on the ignition lever (not shown). Then,
A temperature sensor 17 is activated by a switch attached to the ignition lever. The temperature sensor 17 measures the temperature of the outer tube 11 portion. In this case, the core outer cylinder 11
Information that the temperature in the area is high is sent to the built-in computer.

The built-in computer receives this information and instructs the connected circulation pump 13 to "start." Upon receiving this command, the circulation pump 13 is started, and the kerosene 9 is pumped through the oil suction pipe 14 and the circulation tube 1.
5 and is fed into the core outer cylinder 11 from the discharge port 16. This pumped kerosene lowers the temperature of the wick. Then, the temperature of the core outer cylinder 11 also decreases. When the temperature of the core outer tube 11 decreases, the temperature sensor 1
The computer built in 7 receives the temperature information and instructs the circulation pump 13 to "stop".

This completes preparation for ignition.

Next, the wick 10 rises to near the burner 12,
An ignition heater (not shown) ignites the wick.

In this case, since the temperature of the wick is lower, vaporization of kerosene from the wick can be suppressed. Therefore, it does not emit a bad odor when it is re-ignited.

Also, since the system does not involve lifting the burner 12 to ignite it, no black soot is produced.

Furthermore, since the vaporization of kerosene is suppressed, the kerosene gas concentration is reduced. In addition, circulation tube 15
As a result of the air accumulated inside being supplied to the core outer cylinder 11 section, oxygen is supplied to the core 10 section. These two effects work together to create a state where it is easy to re-ignite, so no white smoke is produced when re-igniting. It also becomes easier to ignite.

In addition, in the wick-type kerosene stove according to the present invention, the above-mentioned operation is performed in the case of relighting the fire when a short period of time has passed since the fire went out. If some time has passed since the fire went out and the temperature of the wick has dropped sufficiently, when the ignition lever is pressed, the above operation will not be performed and the ignition will start immediately. That is, normal ignition.

This is because, as mentioned above, the temperature sensor
The temperature of the first part is measured and the temperature information is sent to the built-in computer, but even after receiving this information, the built-in computer judges that the temperature is low enough and does not instruct the circulation pump 13 to "start". .

That is, the built-in computer starts the circulation pump 13 when the temperature of the core outer cylinder 11 is high, and starts the circulation pump 1 when the temperature of the outer core cylinder 11 falls.
It is programmed to stop 3.

In addition, in the above embodiment, just before ignition, the core outer cylinder part 1
Although the case is shown in which the temperature sensor 17 has the function of feeding kerosene into the wick 10, lowering the temperature of the wick 10, and then igniting the wick 10, the present invention is not limited to this. In other words, even if a temperature sensor is used that has the function of activating the circulation pump 13 immediately after extinguishing, feeding kerosene into the wick outer cylinder part 11, lowering the temperature of the wick 10, and completing preparations for ignition. , the same effects as in the embodiment can be achieved.

In addition, in this embodiment, the temperature sensor has a built-in computer that commands the start and stop of the circulation pump.
Although the above-mentioned operation is performed automatically, the present invention is not limited to this. A thermometer is attached to the core outer cylinder 11, and when the temperature is judged to be high with the naked eye, the pump can be manually operated. The same effects as in the embodiment can also be achieved by activating the .

Furthermore, although this embodiment shows a case where a centrifugal pump is used as the circulation pump, the present invention is not limited to this, and even if a diaphragm type simple pump and a piston type simple pump are used, the same effects as in the example can be obtained. can be realized.

[Effects of the invention] As described above, according to the wick-type kerosene stove according to the invention, since the passage for supplying kerosene is provided in a part of the wick outer cylinder, the kerosene is immediately supplied to the wick after extinguishing. Kerosene can be pumped in to lower the temperature of the wick.

Therefore, even if the anti-seismic fire extinguisher works and extinguishes the kerosene stove, it will not emit black soot, white smoke, or bad odors like traditional kerosene stoves.
Relighting is possible. It also becomes easier to ignite.
There has not yet been a wick-type kerosene stove with this kind of performance on the market, and it has been long awaited by consumers.
