CONSTITUTION:When a wick elevation type kerosene heater 16 is extinguished, a micromotor 11 of a smell reducing device 17 is run, and a fan 12 is interlocked. In which case, gas generated from a combustion part 15 is sucked through a discharge passage 9, the internal space of a combustion tank 2, a hole 19 formed in a cover 18 made of resin of the smell reducing device 17 with the aid of the fan 12, and is discharged through a discharge port 20 of the smell reducing device 17. Gas generated during an extinguishing motion is discharged without the passage of it through a combustion cylinder 8, and a smell can by prevented from generation. Disposing of the smell reducing device 17 in the internal space of the combustion tank 2 shields a radiant heat from the combustion part 15 by means of the combustion tank 2, and prevents breakage of deformation of the cover 18 made of resin.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an oil combustor, and in particular to an oil combustor equipped with an odor reduction device for reducing odor caused by gas generated from the combustion part during extinguishing operation. Regarding improvements.

[Prior art]

FIG. 5 shows an enlarged sectional view of essential parts of a top-and-bottom wick type kerosene stove 1 as a representative example of a conventional oil combustor, which is the background of the present invention. The wick 4 sucks up the kerosene 3 inside by capillary force upward in the figure, and the upper end of the wick 4 protrudes from the upper end of the 8 guide path 7 formed by the outer core cylinder 5 and the inner core cylinder 6, and the combustion cylinder 8 Heating is achieved by combustion inside the building.

To extinguish the fire in the wick type kerosene heater 1, the upper end of the wick 4 is immersed in the 8 guide passages 7, as shown in FIG. 5, and the supply of air to the wick 4 is cut off. This is done by reducing the evaporation of the kerosene 3.

However, during the extinguishing operation of the above-mentioned upper and lower wick type kerosene stove 1, incomplete combustion gas is generated due to so-called slow flame combustion for several seconds to several tens of seconds after the wick 4 is immersed into the 8 guide paths 7. Furthermore, even if the flame combustion is extinguished, unburned gas is generated until the wick is cooled. When these gases pass through the combustion tube 8, which is still at a high temperature, they are thermally decomposed and emit a bad odor.Therefore, as a way to reduce this bad odor, the gas generated during the extinguishing operation is exhausted without passing through the combustion tube 8. I thought about that.

That is, at the time of extinguishing the fire, the inner diameter of the wick outer cylinder 5 is expanded slightly below the position of the upper end of the wick 4 when the wick 4 is immersed into the inner space 7 of the wick chamber, and communicated with the internal space of the combustion tank 2. An exhaust passage 9 is formed. Further, the upper wall 2 of the combustion tank 2. A hole 10 is bored in the hole 10, and an odor reduction device 13 consisting of a micromotor 11, a fan 12, etc. is arranged on the upper surface of the hole 10, and the air in the internal space of the combustion tank 2 is exhausted during extinguishing operation. . By doing so, the gas generated during the fire extinguishing operation is exhausted without passing through the combustion tube 8, thereby preventing foul odors. Here, 21 is the damper and #! This prevents outside air (air) from flowing back into the combustion tank 2 during combustion or when the odor reduction device 13 is not operating.

[Problem to be solved by the invention]

In such a conventional kerosene stove 1 with a top-and-bottom wick, the odor reduction device 13 is housed in a resin cover 14 molded with a luxurious sealant for ease of manufacture, and is housed in a resin cover 14 formed from a luxurious sealant for ease of manufacture. ．． is placed on top.

However, the upper wall 21 of the combustion tank 2 receives radiant heat from the combustion section 15 including the combustion tube 8 and becomes hot, and therefore the resin cover 14 of the odor reduction device 13
There were problems such as cracking or deformation, and there were concerns that it would not be able to withstand long-term use.

Therefore, an object of the present invention is to provide an oil combustor equipped with an odor reduction device that can withstand long-term use without being affected by radiant heat from the combustion θ.

[Means to solve the problem]

The main means of the present invention to achieve the above object is to include an odor reduction device for exhausting gas generated from the combustion part during extinguishing operation of the oil combustor, and the odor reduction device is covered with a resin cover. An oil combustor housed in an oil combustor, characterized in that a part or the whole of the resin cover of the odor reduction device is disposed in a position where it is difficult to receive radiant heat from the combustion part. be.

[Effect]

According to the present invention, part or all of the resin cover of the odor reduction device is disposed in a position where it is difficult to receive radiant heat from the combustion section. The impact can be significantly reduced, making the material durable for long-term use.

〔Example〕

Next, embodiments embodying the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. here the first
The figure is an enlarged cross-sectional view of the main parts of a top-and-bottom kerosene stove as a representative example of the oil burner according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of the main parts showing a modification of FIG. 1. Figure 3 is an enlarged sectional view of the main part when the odor reduction device is installed on the side wall of the combustion tank, and Figure 4 is the main part when a part of the odor reduction device is installed in the internal space of the combustion tank. It is an enlarged sectional view.

In the following description, the same reference numerals will be used for the same elements as those of the conventional wick type kerosene stove 1 shown in FIG. 5, and the description will be omitted. Further, the following examples are merely specific examples of the present invention, and are not intended to limit the technical scope of the present invention.

In this embodiment, the wick type kerosene stove 16 is different from the conventional wick type kerosene stove 1, as shown in FIG. This point is placed in the internal space of No. 2.

Therefore, when the wick type kerosene stove 16 is extinguished, the micromotor 11 of the odor reduction device 17 is activated, and the fan 1
2 are linked. Then, the fan 12 sucks the gas generated from the combustion section 15 through the exhaust passage 9, the internal space of the combustion tank 2, and the hole 19 formed in the resin cover 18 of the odor reduction device 17, thereby removing the odor. The air is exhausted from the exhaust port 20 of the reduction device 17. By doing so, the gas generated during the fire extinguishing operation can be exhausted without passing through the combustion tube 8, and bad odors can be prevented.

Then, such an odor reduction device 17 is installed in the combustion tank 2.
By disposing it in the internal space of the combustion tank 2, the radiant heat from the combustion section 15 is blocked by the combustion tank 2, and the resin cover 18
No cracking or deformation occurs.

In addition, like the odor reduction device 17 described above, the resin cover 1
If the exhaust port 20 side (the right side in the figure) of 8 is formed to be lower than the hole 19 side, the gas sucked from the hole 19 and exhausted to the exhaust port 20 will liquefy due to dew on the way. If so, it is smoothly returned to the combustion tank 2 via the communication port 22.

Furthermore, as shown in FIG. 2, when the exhaust port 20 of the resin cover 18 is opened and connected slightly below the equilibrium oil level of the communication port 22, the odor reduction device 17. In order to operate effectively, a slightly higher pressure is required to overcome the pressure of the curved surface, but normally the damper 21 is not needed because the oil level blocks the exhaust port 20.

Note that the location where the odor reduction device 23 is installed is not limited to the internal space of the combustion tank 2 as described above, but may be any location where it is difficult to receive radiant heat from the combustion section 15. , as shown in Fig. 3, the combustion tank 2
It may also be the side wall 2t of.

Further, it is not necessary to arrange the entire odor reduction device 24 in a position where it is difficult to receive radiant heat from the combustion section 15;
As shown in the figure, if a portion of the resin cover 25 including the fan 12 is placed in a position where it is difficult to receive radiant heat, cracking or deformation of the resin cover 25 can be prevented.

〔Effect of the invention〕

According to the present invention, an odor reduction device is provided for exhausting gas generated from the combustion part during extinguishing operation of the oil combustor,
In an oil combustor in which the odor reduction device is housed within a resin cover, a part or the whole of the resin cover of the odor reduction device is disposed in a position where it is difficult to receive radiant heat from the combustion section. An oil combustor is provided, which can protect the resin cover of the odor reduction device or the odor reduction device itself from the effects of radiant heat from the combustion section, and can therefore be used for a long period of time.
