Description

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

<Prior Art> FIG. 4 shows a conventional electrical circuit diagram for deodorization. Reference numeral 1 denotes a switch, which is soldered to a printed circuit board 2 as shown in FIG. It is turned on and off by an interlocking plate 44.

For normal extinguishing, when the extinguishing button 4a is pressed in the on-core ignition state shown in FIG. is disengaged from the engaging portion 4h of the groove 4g of the fire extinguishing lever 4e, the wick is lowered, and the fire is extinguished. Also, anti-seismic automatic fire extinguishing system A
As is well known, it consists of a weight 7a, a chain 7b, and a locking member 7e rotatably supported on a base plate 7c by a shaft 7d. When the weight 7a falls due to vibration, the locking member 7e moves counterclockwise. The pin 7h that was engaged with the engaging portion 7g of the hole 7f comes off against the spring 7k, and the manual fire extinguishing device B including the operating plate 7m is activated, and the main shaft S
rotates downward. Further, the relationship between the switch 1 and the interlocking plate 4 is such that the switch is only switched when the core is completely lowered. And switch 1
The timer circuit 5 is activated by the ON operation, and the electric motor 6a of the deodorizing device 6 is activated for a predetermined period of time to reduce the bad odor generated from petroleum etc. when the fire is extinguished.

However, in the above configuration, it is difficult for the user to judge whether or not the deodorizing device 6 is operating when extinguishing a fire. In particular, even though the fire has been extinguished, if the wick is not completely lowered, the deodorizing device 6 will not operate and a foul odor will occur, but the user may not notice this or it will take time to notice.

<Purpose> In view of the above, an object of the present invention is to provide a liquid fuel combustion device in which it is possible to visually detect that the deodorizing device is operating.

<Embodiment> Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 and 2. The liquid fuel combustion device of the present invention is provided with an odor prevention device 6 that operates simultaneously with extinguishing the fire, and the odor prevention device is equipped with the odor prevention device 6. A drive circuit 10 is electrically connected to an optical display device 8 for displaying the operating state, and operates the deodorizing device 6 and the optical display device 8.
The switch 1 is turned on and off by the interlocking plate 4 of the fire extinguisher main body 3 (see Figure 4), and the switch 1
It is comprised of a timer circuit 5 (such as a CR timer) that is activated when the deodorizing device 6 and the optical display device 8 are turned on and supplies power to the deodorizing device 6 and the optical display device 8.

The optical display device 8 includes a light emitting diode 8A (a lamp may be used) and a resistor 11, and is arranged so as to be visible from the front panel (not shown) of the combustion apparatus main body. The light emitting diode 8A and the electric motor 6a of the deodorizing device 6 are connected to a timer circuit 5.
are connected in parallel. Note that 12 in the figure is a power supply. Further, as shown in FIG. 2, the deodorizing device 6 is provided with an intake port 14 on the upper wall of the combustion tank 13, and above which a suction fan 15 and an electric motor 6a are arranged. An exhaust duct 17 is formed by the mounting case 16 and the combustion tank 13, and gas is discharged from an exhaust port 18 formed at one end of the mounting case 16. When the upper end of the wick 19 sinks into the wick guide tube 22 formed by the inner core tube 20 and the outer core tube 21 due to the extinguishing operation or the activation of the vibration sensing device, and the extinguishing operation is achieved, the electric motor 6a is activated and the combustion tank It is configured so that the air and kerosene gas in the internal space of No. 13 are sucked.

Note that the other configurations are similar to the conventional example shown in FIGS. 4 and 5.

In the above configuration, when the wick descends when extinguishing,
When the interlocking plate 4 is activated and the core is completely lowered, the interlocking plate 4 turns on the switch 1. When switch 1 is turned ON, timer circuit 5 is activated.
The electric motor 6a is turned on for a certain period of time to reduce the odor generated from oil and the like. At the same time, the light emitting diode 8A of the optical display device 8 connected in parallel to the electric motor 6a also continues to emit light while the electric motor 6a is operating.
After a certain period of time has elapsed, the light goes out when the electric motor 6a stops.

Note that if the wick is not completely lowered due to the use of defective kerosene, etc., the switch 1 will not turn on, and neither the deodorizing device 6 nor the light display device 8 will operate. Therefore, when the light emitting diode 8A does not light up when the fire is extinguished, it also functions to notify that the wick is not lowered. In addition, the light display device 8 includes a light emitting diode 8A.
If you use one with a forward voltage value of 2.2 to 2.4 V or more, if the voltage of the dry cell battery falls below the forward voltage, the light emitting diode 8A will become dark and this will also notify you that the dry cell battery is exhausted.

FIG. 3 shows another embodiment of the present invention, in which, instead of the timer circuit 5 of the first embodiment, a bimetal thermostat 25 that turns on at a temperature above a certain temperature is connected in series with the switch 1. death,
A parallel connection body of a light emitting diode 8A and a motor 6a are connected in series to these series connection bodies to form an electric circuit. Even in this case, the optical display device 8 operates simultaneously with the operation of the electric motor 6a.

<Effects> As is clear from the above explanation, the present invention is provided with an odor control device that operates simultaneously with extinguishing the fire, and an optical display device is electrically connected to the odor control device to display its operating status. The present invention relates to a characteristic liquid fuel combustion device.

Therefore, according to the present invention, since the optical display device allows the user to visually confirm that the deodorizing device is operating when extinguishing a fire, the user can easily sense whether or not the deodorizing device is operating. It has excellent effects.
