Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an odor reducing device for a petroleum combustor having a core above and below.

[0002]

2. Description of the Related Art Generally, in an upper and lower oil combustor, when a wick is lowered to extinguish a fire, petroleum vapor which continues to vaporize from the wick enters a combustion cylinder provided above the wick and is thermally decomposed by residual heat to be strong. There was a problem that odor was generated. In particular, when an emergency fire extinguishing device is used to perform an instant fire extinguishing operation, the temperature of the combustion cylinder is high and the wick drops rapidly, so that the fire is extinguished instantly and the amount of unburned gas generated increases. Therefore, the time and amount of uncombusted gas after fire extinguishing in the combustion cylinder is increased, and a stronger odor is generated.

Therefore, recently, in order to reduce the odor at the time of extinguishing the fire, an odor absorbing device such as a fan is provided at the same time as the fire extinguishing operation.
It has been proposed that after absorbing the vaporized petroleum vapor from the wick into the oil tank, the oil (odor) is released to the outside without being thermally decomposed.

FIG. 4 shows a petroleum combustor with an above and below core having such a device. When the wick 21 is lowered by the operating lever 20 to extinguish the fire, the switch 22 is activated, the timer element 23 activates the motor 24, the fan 25 starts rotating, and the petroleum vapor that continues to vaporize from the upper portion of the wick 21 is indicated by an arrow. The gas is sucked into the oil tank 26, and the odorless gas is discharged to the outside. According to this upper and lower wick type oil combustor with an odor absorbing device, the petroleum vapor that continues to be generated after extinguishing is not released into the high temperature combustion cylinder 27 but is released into the atmosphere through the tank 26, so that the petroleum vapor is thermally decomposed. The stimulating odor generated by the treatment was eliminated, and the odor could be greatly reduced.

[0005]

However, since the odor absorber having such a conventional structure starts the odor absorbing operation immediately after extinguishing the fire, a large amount of unburned unburned fuel remains in the combustion cylinder in an incomplete combustion state immediately after extinguishing the fire. Even gas will be forcibly sucked and released outside the body. Thus, when the unburned gas is forcibly sucked in the combustion cylinder at a very high temperature immediately after extinguishing the fire, the unburned gas undergoes thermal decomposition in the high temperature atmosphere of the combustion cylinder during the suction process, and acetaldehyde which becomes a pungent odor. Will be generated in large quantities. Furthermore, immediately after the fire is extinguished, the temperature of the combustion cylinder is high, so the petroleum vapor is being sucked into the upper layer due to the draft effect. Turbulence occurs,
Smooth suction does not work. In other words, the unburned gas is retained in the combustion cylinder, the time required for the thermal decomposition of the petroleum vapor is extended, the amount of acetaldehyde generated is further increased, and the pungent odor is severe.

Further, the heat generation amount of the wick type oil combustor changes depending on the ambient temperature and the oil temperature. When the temperature is low, the amount of vaporization from the wick decreases, so the heat generation amount decreases, and when the temperature rises, the heat generation amount. Is on the rise. In connection with this, the extinguishing odor also tends to be stronger as the calorific value is larger, and to be milder as the calorific value is smaller. That is, when the temperature is high, the extinguishing odor is tight, and when the temperature is low, the extinguishing odor is reduced.

[0007] However, the operation of the conventional odor absorber does not depend on the change of environmental conditions, but is operated for a certain period of time preset to obtain the odor absorbing effect at the most severe extinguishing odor condition, that is, at the upper limit of the operating temperature range. It had a great influence on the life.

The present invention has been made in view of the above circumstances. After the extinguishing operation, the operation of the odor absorbing fan is forcibly stopped for a predetermined time, and the unburned gas immediately after the extinguishing is burned in the high temperature combustion cylinder. At the same time, after the combustion cylinder cools and the draft effect is weak, the odor absorbing fan is operated to effectively suck the unburned gas, thereby improving the odor absorbing effect. Another object is to control the operating time of the odor absorbing fan according to the ambient temperature so that the odor absorbing operation can be performed efficiently and the battery life can be extended.

[0009]

In order to solve the above-mentioned conventional problems, the present invention forcibly stops the operation of the odor absorbing fan for a predetermined time by a fire extinguishing operation, and after a lapse of the predetermined time, operates the odor absorbing fan to operate at ambient temperature. The operating time is set according to the above. That is, a switch arranged at the fire extinguishing position of the wick, a first timer element that starts operation when the switch is activated, and a second timer element that starts operation by a time-up signal of the first timer element, The odor absorbing fan motor is provided with the temperature detecting unit for detecting the ambient temperature, and the correcting unit for correcting the timer time of the second timer element by the signal of the temperature detecting unit.
It is connected to the output of the timer element.

With the above structure, the first timer element for stopping the odor absorbing motor for a predetermined time is operated by the switch which is interlocked with the operation lever and operates at the fire extinguishing position of the lamp core, and after the predetermined time has elapsed, the second timer element is activated. Operate the odor absorbing motor. At the same time, the operation time of the odor absorbing motor is corrected according to the ambient temperature obtained by the temperature detecting section, so that the odor absorbing operation can be efficiently performed and the battery life can be extended.

That is, the unburned gas immediately after extinguishing is completely burned in the high temperature combustion cylinder, the draft effect in the combustion cylinder is alleviated, and the suction action starts to operate normally before the odor absorbing operation is started and the ambient temperature is raised. Since the odor absorbing operation time is controlled according to the above, unnecessary odor absorbing operation is eliminated, and an effective odor absorbing function and battery life can be extended.

At the same time, the operation time of the odor absorbing motor is corrected according to the ambient temperature obtained by the temperature detecting section, so that the odor absorbing operation can be efficiently performed and the battery life can be extended.

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

First, the structure of the odor absorber of the present invention will be described with reference to FIG. Reference numeral 1 is a fixed tank, 2 is a wick, and the wick 2 is moved up and down by an operating lever 8 via a metal fitting (not shown). Reference numeral 3 denotes a lead guide tube, which works to smoothly move the wick 2 up and down. Reference numeral 4 denotes an inner fire tray provided for the purpose of improving the fire extinguishing performance, and 5 an outer fire tray for improving the fire extinguishing performance and adjusting the air for vaporization of the wick 2. Reference numeral 6 is an inner flame cylinder, and 7 is an outer flame cylinder, both of which mix the vaporized gas of the wick 2 and the combustion air to perform combustion. Reference numeral 8 denotes an operation lever, which is interlocked with the wick 2 via a metal fitting, and which pushes the lever of the switch 9 at the fire extinguishing position pushed up to the uppermost end to switch the contacts. Reference numeral 10 is an ignition heater, which is energized when the operating lever 8 is set to the ignition position,
Light up. Reference numeral 11 is an odor absorbing fan, and 12 is a motor for forcibly sucking incompletely combusted gas and vaporized gas of the wick 2 after extinguishing the fire, and discharging it to the outside of the main body to reduce odor generated in the combustion cylinder.

Reference numeral 13 is a temperature detecting element, and 14 is a temperature detecting portion, and these 13 and 14 detect the ambient temperature of the combustor. A correction unit 15 corrects the operating time of the odor absorbing motor 12 based on the temperature data of the temperature detecting unit 14. Reference numeral 16 is a first timer element, which is activated by a signal from the switch 9 and stops the operation of the odor absorbing motor 12 for a preset time. Reference numeral 17 denotes a second timer element, which is activated by the time-up signal of the first timer element 16 and supplies an operation signal to the odor absorbing motor 12 for the operation time corrected by the correction unit 15. Reference numeral 18 denotes a battery, which is a power source of the odor absorbing device.

The operation of the above configuration will be described with reference to FIG. The kerosene supplied from the cartridge tank to the tank 1 so as to keep a constant oil level is sucked up by the wick 2 and vaporized at the tip of the upper part. First, when the operation lever 8 is pushed down, the wick 2 is pushed up in an interlocking manner and set to the ignition position. At the same time, the ignition heater 10
Is energized to ignite, ignites around the entire circumference of the cylindrical wick 2, and becomes a combustion state. Due to this combustion, vaporization of the wick 2 is promoted, and the inner flame cylinder 6 and the outer flame cylinder 7 hold flames to shift to a normal combustion state.

Next, when the fire extinguishing operation is performed by the operation lever 8 or the fire extinguishing operation is performed by the operation of the fire extinguishing button or the anti-vibration device, the wick 2 is lowered in conjunction with the operation lever 8 to extinguish the fire. At the same time, the operating lever 8 of the switch 9 provided at the ignition position also moves to the fire extinguishing position, so that the contacts are switched. When the contact switches, the first timer element is activated,
The operation of the second timer element 17 is stopped for a preset time. The first timer element 16 burns unburned gas remaining in the combustion cylinder by extinguishing the fire during counting. When the first timer element 16 counts up, the second timer element 17 starts operating to operate the odor absorbing motor 12 to remove unburned gas remaining in the combustion cylinder and petroleum vapor vaporized from the wick 2. Aspirate and discharge out of the body.

On the other hand, the temperature detecting element 13 and the temperature detecting section 14
The ambient temperature is read by, the correction unit 15 calculates the correction value of the operating time of the second timer element 17 based on the data, and the target value of the operating time is updated.
The updated target value is sent to the second timer element 17, and the operation of the odor absorbing motor 12 is controlled according to the target value.

In addition, the temperature correction by the correction unit 15 is shown in FIG.
As shown in (4), the correction characteristic is corrected. That is, when the temperature rises, the operating time of the odor absorbing motor 12 is corrected so as to be extended, and when the temperature becomes low, the operating time of the odor absorbing motor 12 is corrected so as to be shortened, and the efficient operation of the odor absorbing motor is performed to reduce power consumption. We are trying to reduce the battery life and extend the battery life.

[0022]

As described above, since the odor absorbing device of the present invention delays the odor absorbing operation after extinguishing the fire by a predetermined time,
The unburned gas with a high concentration immediately after extinguishing will be burned in the high-temperature combustion cylinder, the amount of acetaldehyde which is a pungent odor can be suppressed, and the draft effect in the combustion cylinder is mitigated. Since the fuel gas and petroleum vapor are sucked, an effective suction action works and the odor absorbing effect is also improved.

Further, by correcting the time of the odor absorbing operation according to the ambient temperature and operating the odor absorbing motor efficiently, the power consumption can be reduced and the battery life can be extended.
