Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove with an air cleaner which is provided with an air cleaner to purify indoor air while blowing warm air.

[0002]

2. Description of the Related Art Heretofore, there is known a petroleum stove with a fan in which air heated by a combustion device is blown from a blower opening by a fan.

[0003]

However, such a petroleum stove with a fan simply blows air heated by a combustion device, so that the air in the room contains carbon monoxide, nitrogen oxides, or the like. It was markedly polluted by toxic gas, and the odor peculiar to an oil stove was generated. In the case of a so-called fan heater in which oil is vaporized and burned, poisonous gas, odor, etc. are considerably reduced, but air is still contaminated.

As described above, since the conventional oil stoves have hardly taken any measures against toxic gases, it is necessary to pay attention to the ventilation at all times during combustion. For this reason, the windows are sometimes opened to ventilate the air. It took time to do. In addition, the odor sometimes became strong especially after ignition and extinguishing for a while. Further, the conventional oil stove with fan and fan heater take in dirty air in the room, and since the taken-in air is heated and discharged together with the dirty air, the inside of the stove and the air outlet are easily soiled. Therefore, it was often necessary to clean the stove.

DISCLOSURE OF THE INVENTION The present invention has a relatively simple structure and is designed to prevent the air in the room where the stove is used from being contaminated as much as possible. Each of which is equipped with a fan for taking in the air and an electrostatic precipitator that allows the air taken in by the fan to pass therethrough, and combines the clean air that has passed through the electrostatic precipitator with the air that has been heated by the combustion device. The present invention relates to a stove with an air cleaner, which is characterized in that air is blown from a blower opening.

In these FIGS. 1 and 2, an air intake 2 is provided on the side surface of the outer casing 1 of the oil stove,
Inside the air intake port 2, a first filter 3 made of a mesh filter such as urethane home is provided. An air intake chamber 4 is provided inside the outer casing 1 at a position facing the first filter 3, and a fan 5 is provided in the air intake chamber 4. Above the fan 5, a duct 6 is provided in the air intake chamber 4
And is vertically extended upward.
In the vicinity of the lower opening in the duct 6, a plurality of flat plate-shaped dust collecting electrodes 7 forming an electrostatic dust collector are provided in parallel with each other, and an activated carbon filter containing activated carbon or the like is provided above the dust collecting electrodes 7. A second filter 8 consisting of

A control device 9 for controlling the operations of the electrostatic precipitator and the fan 5 is provided on the lower side of the duct 6. The control device 9 is provided with a timer device, and the electric dust collector and the fan 5 can be timer-controlled by operating the switch 10 and the knob 11 arranged on the side surface of the outer casing 1. Has been done. Further, since the dust collecting electrode 7 is covered and shielded by the metal duct 6, the dust collecting electrode 7 is configured so as not to be affected by noise or the like to the outside.

The upper opening 6a of the duct 6 is a horizontal duct 12
Is in communication with. The horizontal duct 12 is provided in the lower portion of the top plate 1a of the outer casing 1 with a wide space, and an opening at one end thereof is a blower port 13 provided in the upper front portion of the outer casing 1.
Is in communication with.

The combustion cylinder 14 arranged in the lower part of the combustion gas chamber 26 in the outer casing 1 is an oil tank 15 as conventionally known.
It is configured to absorb and burn oil filled with oil. Above the combustion cylinder 14 and below the horizontal duct 12, there is provided a duct 16 for sending the air heated in the combustion cylinder 14. On the lower surface of the duct 16, an intake port 17 for taking in the heated air in the combustion gas chamber 26 is formed in an elongated shape, and an outlet 18 of the duct 16 is formed in an elongated shape to form the horizontal duct 12 in the horizontal duct 12. It is in communication.

A third filter 19 is fitted in the outlet 18. As the third filter 19,
For example, a slender cloth filter can be used in which a carrier layer made of silica or alumina is formed on the surface of silica cloth made of silica fiber, and a metal catalyst such as platinum is used. Such a filter is used in the combustion cylinder 14
Since the heated air is allowed to pass smoothly while effectively absorbing the toxic gas contained in the heated air at 1, the clean air can be obtained.

An air cleaner is constituted by the fan 5, the filters 3 and 8 and the electrostatic precipitator. The radiant heat of the combustion cylinder 14 is radiated to the outside either directly or after being reflected by the reflection plate 20.

In addition to the above, the oil stove according to the present embodiment is further provided with a core upper and lower knob 22, a fan switch 23, an ignition switch 24, an oil meter 25, etc. on a front panel 21 thereof as conventionally known. . In addition, the switch 10 and the knob 11 of the timer device described above are attached to the front panel 2
It may be arranged at 1. The oil stove has a structure in which the filters 3, 8 and 19 can be easily replaced, and the electric dust collector can be easily taken out and cleaned.

Since the petroleum stove according to this embodiment is constructed as described above, when the fan switch 23 is operated to rotate the fan 5, the outside air is taken in from the air intake port 2, and first, the filter 3 This removes dust with coarse particles. The air that has passed through the filter 3 then reaches the dust collection electrode 7 via the air intake chamber 4, where fine particles of dust are removed, and then further passes through the filter 8 to obtain fine dust and Odor etc. are removed and it becomes clean air. This clean air rises in the duct 6 by the force of the fan 5 and the horizontal duct 12
Enters and spreads inside the horizontal duct 12.

On the other hand, the air heated in the combustion cylinder 14 rises by convection, enters the duct 16 from the intake 17, and reaches the filter 19 through the duct 16. Then, by passing through the filter 19, the toxic gas is effectively removed and becomes clean heated air. This clean, heated air enters the horizontal duct 12,
The force of the fan 5 merges with the flow of the clean air that is sent, and becomes clean warm air and is discharged from the blower port 13.

According to the present embodiment described above, clean hot air is constantly discharged during combustion, and the air taken in from the air intake 2 is purified by an air cleaner and heated clean air. As it is discharged again, the air in the room is circulated while being purified by the air cleaner. Therefore, while heating the room, the air in the room can be purified at the same time. Therefore, even if combustion is continued for a long time in a completely closed room, the number of times ventilation is performed can be made smaller than in the conventional case.

Further, the odor after ignition can be eliminated, and the odor after extinguishing can be removed by operating the fan and the electrostatic precipitator for a predetermined time even after extinguishing the fire by using the timer device. Further, it can be used as an air cleaner by operating the fan 5 and the electrostatic precipitator when oil is not burned.

Further, the electrostatic precipitator, the filters 3, 8, 1
Since the 9, tacts 6, 12 and the control device 9 can be arranged by utilizing the empty space of the conventional oil stove with a fan described above, the conventional outer casing can be used almost as it is. Moreover, the fan for the air cleaner and the fan for blowing the warm air can be used together by the single fan 5, so that the conventional oil stove with a fan can be realized without extensive modification. In addition, it is possible to minimize the cost increase due to the oil stove with an air cleaner. In addition, a timer device is provided, making it convenient to use.
Moreover, since the electrostatic precipitator is shielded, noises and the like do not affect nearby equipment.
