Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air cleaning device used in a building such as a condominium.

[0002]

[Prior Art]

 Recently, with the progress of building technology, the number of high-rise apartments has increased rapidly in order to make effective use of land. Such condominiums have a highly airtight structure in order to improve heat retention and soundproofing. On the other hand, since the airtightness is high, when there are people in the room, the air becomes dirty over time, so it is necessary to take in fresh air from the outside on a regular basis. The air flow is fast and so-called building wind blows when the apartment is built in. Therefore, if you open the window and take in outside air, a strong wind will enter the room, making it difficult to open the window. Is the reality.

Therefore, an air passage is formed that penetrates from the inside of the room to the outside, and the outside air is taken into the room by this air passage.

[0004]

[Problems to be solved by the device]

 However, the amount of exhaust gas has increased since the traffic volume has been extremely high these days, and as a result, the pollution of the outside air has become severe, especially near the main roads. In addition, even if the vehicle is away from the main road, exhaust gas diffuses and is carried by air currents to a long distance.

For this reason, even if outside air is taken into the room from the ventilation passage in an apartment or the like, there is a problem that the air in the room is contaminated by the dirt of the outside air itself.

The present invention has been made under such circumstances, and an object of the present invention is to provide an air purifying apparatus capable of suppressing dirt in the air inside a building.

[0007]

[Means for Solving the Problems]

 The invention of claim 1 is characterized in that an air passage for taking in outside air is formed between the inside of the building and the outside, and a filter portion for cleaning air is provided in this air passage.

The invention of claim 2 is characterized in that it has a suction fan for sucking outside air from the outside of the ventilation passage toward the inside of the building.

[0009]

[Action]

 The dust contained in the outside air is removed by the filter unit, so the cleaned air is taken into the room. If a suction fan is provided, the outside air can be forcibly taken in even when there is no wind, and an appropriate air flow can be created inside the room by adjusting the air resistance and suction pressure of the filter section. can do .

【Example】

 FIG. 1 is a vertical sectional view showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a wall portion that separates the inside and the outside of a room in a condominium, for example. The wall portion 1 has ventilation holes 2 that form a part of a ventilation passage for taking in outside air from inside the room to outside. It is formed to penetrate.

A ventilation tube 3 is fitted into the ventilation hole 2, and the ventilation tube 3 has a flange portion 31 formed at the peripheral edge on the room side (one end side). It is detachably attached to the wall portion 1 by means of 4 or the like. For example, a cylindrical filter portion 5 for removing airborne dust particles such as dust in the air is tightly fitted inside the ventilation tube 3, and the filter portion 5 is provided outside the ventilation tube 3. Along the inner peripheral surface near the peripheral portion of the side (the other end side), for example, projection-like locking portions 32 formed at several places are prevented from being pulled out to the outside. A cover 6 having, for example, an air intake 61 on the lower side is attached to the wall portion 1 on the outer side of the ventilation hole 2 so that the outside wind does not directly hit the ventilation hole 2.

According to such an embodiment, outside air enters the ventilation hole 2 through the air intake port 61 of the cover 6 and is taken into the room through the filter portion 5, but dust contained in the air is included. Etc. are removed by the filter unit 5. When the filter part 5 becomes dirty and it is time to replace it, remove the screw 4 and pull out the ventilation tube 3 to the room side, push the filter part 5 from the other end side to the one end side, The replacement work can be easily performed by inserting the ventilation tube 3 from the side and inserting the ventilation tube 3 into the ventilation hole 2.

Further, as shown by a chain line in FIG. 1, it is preferable to attach a cover 21 for opening and closing the opening of the ventilation hole 2 on the room side so as to engage with the peripheral edge of the flange 31. For example, it is more preferable that the outside air can be taken in only when necessary, and that the cover 21 can be combined with a shutter means capable of adjusting the opening area so that the outside air can be taken in with an appropriate amount even if the outside wind is strong. ..

In the above, according to the present invention, as shown in FIGS. 2 and 3, at the position facing the opening of the ventilation hole 2 on the room side, the suction fan 7 can be opened and closed by the hinge 71. You may make it attach to the wall part 1.

In this way, even when there is no wind outside, the outside air can be forcibly taken into the room, and a comfortable wind can be formed by adjusting the suction pressure of the suction fan 7. ..

When a filter having a gas adsorption function such as hydrocarbon, which is an exhaust gas component, is also incorporated in the filter unit 5, the air resistance of the filter unit 5 becomes considerably large, but a suction fan is used. By setting the suction pressure of 7 to a value commensurate with the air resistance, it is possible to take in an appropriate amount of outside air into the room while adsorbing and removing exhaust gas components, which is very effective. .. Further, in this case, even if the external wind is strong, the wind pressure is suppressed by the air resistance of the filter portion 5, so that the air can be taken in according to the suction pressure of the suction fan 7.

Further, if the suction fan 7 is attached so as to be openable and closable as described above, it is easy to replace the maintenance, particularly the filter part 5. The suction fan 7 may be attached to the wall portion 1 by means of screws or the like in a detachable manner.

Here, in the present invention, as shown in FIG. 4, a first filter portion 5A for dust and a second filter portion 5B for gas adsorption are provided in the ventilation tube 3 on the front stage side and the rear stage side. It is also possible to provide each of them in a two-stage configuration, and such a configuration has an advantage of being able to prevent clogging of the gas adsorption filter portion 5B.

Further, in the present invention, if the wind direction regulating means 8 is provided at the outlet of the suction fan 7 as shown in FIG. 4 at the same time, it is convenient because the outside air can be taken in according to the layout of furniture in the room. ..

In the above, when arranging the filter part 5 in the ventilation hole 2, it is not necessarily limited to using the ventilation tube 3, and it is set so as to cover the room side opening of the ventilation hole 2. You may.

The present invention can be applied to general residences, office buildings, etc. in addition to condominiums.

[0022]

[Effect of the device]

 According to the present invention, since the filter portion is provided in the ventilation passage, it is possible to take in outside air from which dust and the like have been removed, and to make the room a clean atmosphere.

If a suction fan is provided, even if an adsorption filter for an exhaust gas component having a large air resistance is used as a filter unit, the suction pressure is adjusted according to the air resistance to obtain an appropriate air volume and It can take in clean air from the outside, which is very effective in high-rise apartments, for example.
