Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an odor reduction device for a liquid fuel combustion device.

<Prior Art> In conventional liquid fuel combustion devices, combustion gas generated from the combustion wick during extinguishing operation passes through the combustion tube 21 disposed above the combustion wick, thereby producing an odor.
In order to reduce this odor, an odor reduction device is provided, and as shown in FIG.
An attachment case 23 is fixed to the upper surface of the tank 19 so as to surround the tank 19, and a suction motor 24 and a suction fan 24A for sucking odor are attached to the case 23. The exhaust port 25 at the end of the mounting case 23 is connected to the suction motor 2 by a heat shield plate 28.
A refueling tank 29 is removably connected to the tank 19 on the exhaust port 25 side of the heat shield plate 28, and these tanks 19 and 29 are connected to the box-shaped main body A.
The fuel tank 19 is fixed to the floor stand B by a mounting stand 30.

In the above configuration, when extinguishing a fire, the suction device is activated, and the gas generated from the combustion wick 20 is sucked by the suction motor 24, passes through the intake port 22 from inside the fuel tank 19, and is exhausted from the exhaust port 25.

At this time, the gas discharged from the exhaust port 25 is diffused into the fuel tank accommodating part, but since the volume of the tank accommodating part is small, a part of it falls onto the mounting base 30 side.

On the other hand, even if the combustion wick is lowered when extinguishing a fire, the combustion tube 21
Since the temperature is still high, an upward air current is generated inside the combustion tube 21 and the core inner tube 31 communicating therewith, and the combustion air passes under the fuel tank 19 from the outer surface of the fuel tank 19. It is sucked into the central hole of the core inner cylinder 31 from below the core inner cylinder 31 . As shown in Figs. 5 and 6, this sucked combustion air is mixed with highly concentrated gas that has fallen from the tank housing and enters the combustion tube 21 again, so that the gas is partially absorbed by the high-temperature combustion tube 21. It has the disadvantage of being oxidized and producing bad odors such as aldehydes.

<Purpose> In view of the above, the present invention connects an exhaust pipe to the exhaust port and exhausts the sucked gas outside the combustion device main body, thereby effectively exhausting the gas and preventing the gas from re-generating. It is an object of the present invention to provide an odor reduction device for a liquid fuel combustion device that can reduce odor more effectively.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. The odor reduction device for a liquid fuel combustion apparatus according to the present invention includes a fuel tank installed in a combustion apparatus main body A. An exhaust duct 3 is formed between the upper surface 1a of the 1 and the motor mounting case 2 provided on the upper surface 1a, and an exhaust port 4 for discharging odor is formed at the end of the exhaust duct 3. 4 is connected to an exhaust pipe 5 for discharging odor generated when extinguishing a fire to the outside of the combustion apparatus main body A.

As shown in FIG. 2, an inner core cylinder 6 is provided upright from the bottom surface of the fuel tank 1, and a combustion wick 7 is attached to the outer peripheral surface of the inner core cylinder 6 so as to be movable up and down along the inner core cylinder 6. A wick outer cylinder 8 fixed to the upper surface of the tank 1 is fitted onto the combustion wick 7.

Further, an intake port 9 is provided on the upper surface 1a of the fuel tank 1, and a mounting case 2 is fixed to the upper surface of the tank 1 with screws 10 so as to surround the intake port 9.
A suction motor 11 for odor suction is installed in the case 2.
and a fan 11A are attached. The exhaust port 4 at the end of the mounting case 2 is isolated from the suction motor 11 side by a heat shield plate 13, and the tank 1 is connected to the oil supply tank 14 on the exhaust port 4 side of the heat shield plate 13.
are removably connected, and these tanks 1, 14
is housed inside a box-shaped main body A, and the fuel tank 1 is fixed to a floor stand B by a mounting base 15. Further, the box-shaped main body A is placed on the floor stand B, and the combustion cylinder 16 placed on the core outer cylinder is exposed from the main body A. The outlet of the exhaust pipe 5 passes through the back surface 17 of the main body A. As mentioned above, the suction device that sucks out the odor generated when extinguishing a fire is installed in tank 1.
It consists of an intake port 9 on the top surface 1a, a suction motor 11, a suction fan 11A, and a mounting case 2. Further, an exhaust means for guiding the exhaust gas of the suction device to the exhaust hole on the back surface 17 of the combustion device main body A is,
It is composed of an exhaust pipe 5, and the outlet of the exhaust pipe 5 is connected to the main body A.
It is connected to the exhaust hole on the back side 17 of. 18 is Patsukin.

Next, to explain the operation, as shown in FIG. and is discharged from the back surface 17 of the combustion device main body A. That is, the gas passing through the exhaust duct 3 is guided to the back surface 17 of the main body A and is discharged into the room.

This discharged gas is discharged from the back of the main body A and diffused into the room, so its gas concentration becomes extremely low. Therefore, if the gas diffused into the room were to pass from the bottom of the tank 1 through the through hole 6a of the inner core cylinder 6, the gas would enter the combustion cylinder 16, which was still at a high temperature after extinguishing.
Even if it is introduced into the air, it rarely produces a bad odor.

In addition, since the exhausted gas is exhausted from the back of the main body A, the user does not see the exhaust gas that looks white when suction starts, and the gas does not flow around the front of the main body A. , there is little contact with the still-hot combustion cylinder exposed at the front of the main body, and therefore the exhaust gas is less likely to be partially oxidized in the combustion cylinder and produce bad odors such as aldehydes.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects> As is clear from the above explanation, the present invention is provided with a suction device that suctions the odor generated when extinguishing a fire, and an exhaust means that guides the exhaust gas from the suction device to the exhaust hole on the back side of the combustion device main body. The gas emitted when extinguishing a fire is diffused into the room from the back of the main unit, so its gas concentration is extremely low. Even if the fire is led to the combustion tube, which is still hot after the fire has been extinguished, it will hardly produce any bad odor. Therefore, compared to the conventional case in which the gas discharged into the tank storage area flows from the bottom of the tank through the wick inner cylinder to the combustion wick, it is possible to reduce odor more efficiently. It has excellent effects.
