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 and blow 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 oil stoves 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 may become strong especially for a while after ignition and after extinguishing. 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 again together with the dirty air, the inside of the stove and the air outlet are easily soiled, For this reason, it was often necessary to clean the stove.

[0005]

DISCLOSURE OF THE INVENTION The present invention has a relatively simple construction and is designed to prevent the air in the room where the stove is used from being contaminated as much as possible. A combustion gas chamber provided, an air passage provided separately from the combustion gas chamber, a fan for taking in external air to pass through the air passage, a filter for passing the air taken in by the fan, and an electric device. A dust collector is provided, and the clean air that has passed through the filter and the electric dust collector is passed through the air passage without passing through the combustion gas chamber and is blown to the outside. The present invention relates to a characteristic stove with an air cleaner.

1 and 2 show an embodiment of the present invention.

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, and inside the air intake 2, a mesh filter such as urethane home is formed. First filter 3
Is provided. An air intake chamber 4 is provided inside the outer casing 1 at a location facing the first filter 3 described above.
A fan 5 is provided in the air intake chamber 4. A duct 6 is provided above the fan 5 so as to communicate with the air intake chamber 4 and extend vertically 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 shielded by being covered with the metal duct 6 around its periphery, it is configured so as not to have an influence of noise or the like on 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. A duct 16 for sending air heated by the combustion cylinder 14 is provided above the combustion cylinder 14 and below the horizontal duct 12. 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 1
While effectively absorbing the toxic gas contained in the air heated in 4, while passing the heated air smoothly,
It is possible to obtain clean air.

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. Further, this oil stove has a structure in which the filters 3, 8 and 19 can be easily replaced, and further, 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,
It is merged with the flow of the clean air sent by the force of the fan 5, and becomes clean warm air and is discharged from the blower port 13.

According to this embodiment described above, clean hot air is always discharged during combustion, and the air intake port 2
The air taken from is purified by an air cleaner,
Since it is discharged again together with the heated clean air, 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 5 and the electrostatic precipitator for a predetermined time even after extinguishing the extinction by using a 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 duct 9, the ducts 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.

[0019]

According to the stove (including the fan heater) of the present invention, the following effects can be obtained. (1) Since the indoor air circulates while passing through the air cleaner, it is possible to perform heating and air purification at the same time. (2) When the air in the room passes through the air cleaner,
Since various kinds of dust such as coarse particles and fine particles are removed by the filter and the electrostatic precipitator, indoor air can be highly cleaned. (3) Ventilation work can be saved to some extent. (4) Almost no special space is required for installing an air cleaner including a fan, a filter, an electrostatic precipitator, and the like. (5) Since it has a simple structure in which the air cleaner is simply incorporated into the conventional stove, the cost increase can be minimized. (6) Only the air cleaner can be operated by operating only the air cleaner. (7) Since the air in the room can be highly cleaned, the inside of the stove is less contaminated, and therefore the labor of cleaning can be saved to some extent. (8) The clean air that has passed through the filter and the electrostatic precipitator passes through the air passage without passing through the combustion gas chamber that is contaminated by the combustion gas and is blown to the outside, so that only the air cleaner is operated. In this case, highly purified air, which is hardly affected by the dirt caused by the combustion gas, can be blown to the outside.
