[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air cleaning device provided in a building such as an apartment.

[0002]

[Prior Art]

 In recent years, the construction of high-rise condominiums has increased rapidly. This high-rise condominium usually has a highly airtight structure in order to improve heat insulation and soundproofing, so it is necessary to regularly replace the dirty air in the room with fresh air.

However, since high-rise condominiums are densely built in urban areas, so-called strong building wind blows, and it is difficult to open the window and replace the indoor air with the outside air. For this reason, generally, a ventilation path is formed in the wall of the room so as to penetrate from the room to the outside, and the outside air is taken into the room through the ventilation path.

On the other hand, a high-rise condominium is a concrete reinforced concrete structure, and there are few places where natural building materials are used in the room. The number of homes to be placed is increasing.

[0005]

[Problems to be solved by the device]

 However, if the outside air is contaminated by exhaust gas from vehicles passing by in the vicinity of the condominium, this contaminated outside air will be taken into the room as it is, and the river, sludge treatment plant, and chemical factory will also be located near the condominium. If there is a source of offensive odor or a source of offensive odor, the air accompanied by the offensive odor or offensive odor is taken into the room as it is, even if the air freshener is placed in the room. It will be significantly reduced.

On the other hand, as the fragrance, a chemical having a high scent of the fragrance component is usually used in order to make residents feel a sufficient fragrance. In the wood chips such as cypress, which is a natural material, the fragrance component Due to its low scattering properties, high effects cannot be expected even if it is placed indoors.

The present invention has been made under the circumstances as described above, and an object thereof is to purify and purify air and to make the occupants in the room feel a sufficient fragrance. To provide a cleaning device.

[0008]

[Means for Solving the Problems]

 The present invention is characterized in that a filter device to which a fragrance is attached is provided in at least an air passage whose outlet is located on the indoor side.

[0009]

[Action]

 The air taken into the air purifier passes through a filter device to which a fragrance is attached, so that dust is removed and the fragrance component is scattered. It is filled.

Further, even when the air taken into the air purifying device has a bad odor or an offensive odor, these are masked by the aroma component taken into the room.

[0011] Furthermore, since air flows through the air passage, even a chip such as a tree, which has a low fragrance, has a large splattering amount, so that air with a natural and seasonal feeling can be used in the room. Can be satisfied.

[0012]

【Example】

 Hereinafter, an embodiment in which the present invention is applied to, for example, an air cleaning device of a condominium will be described.

FIG. 1 shows, for example, a wall portion that separates the inside and the outside of a condominium, and the wall portion 1 is formed with a ventilation hole 2 that forms a ventilation path for taking in the outside air from the inside to the outside. Has been done.

A ventilation tube 3 is fitted in the ventilation hole 2, and the ventilation tube 3 has a flange portion 31 formed at a peripheral edge portion on the indoor side (one end side), and the flange portion 31 has, for example, a screw or the like. It is removably attached to the wall 1.

A filter device 4 for removing airborne particles such as dust in the air and adhering a fragrance to the air supplied to the room is installed in the ventilation tube 3. The filter device 4 is pulled out to the outdoor side by projection-like locking portions 32 formed at, for example, several places along the inner peripheral surface near the outer peripheral side (the other end side) of the ventilation tube 3. It is locked so as not to come off.

Further, for example, a suction fan 5 is attached to the wall portion 1 at a position facing the indoor side opening of the ventilation hole 2 so as to be openable and closable with respect to the opening by a hinge or the like. In addition, a cylindrical body (not shown) may be provided on the inner peripheral surface of the vent hole 2 formed in the wall portion 1.

If the filter device 4 becomes dirty or the fragrance effect of the fragrance is lost and it is time to replace it, the ventilation tube 3 is pulled out indoors, and the filter device 4 is removed from the ventilation tube 3. The filter and fragrance can be easily replaced.

Here, an example of the structure of the filter device 4 will be described in detail with reference to FIG.

The filter device 4 is composed of a circular filter portion 41 composed of, for example, two mesh bodies 41 a and 41 b, and a frame body 42 having a U-shaped cross section for holding the periphery of the filter portion 41. Since the filter portion 41 has a function of removing suspended particulates such as dust contained in the air from the outside, the shape of the mesh bodies 41a and 41b in order to enhance this function is, for example, a bellows shape having a large surface area. Is preferred.

The same number of locking portions 43 as the locking portions 32 of the ventilation tube 3 are formed at corresponding positions on the flat surface on the outdoor side of the frame 42, and the locking portions 43 have a cross section L. It has a V shape and engages with the locking portion 32 to prevent the filter device 4 from being pulled out toward the indoor side. Further, a large number of minute holes 44 are formed in the plane portion on the outdoor side of the frame body 42, and air from the outside can flow into the room through the minute holes 44 and the filter section 41. It is like this.

On the other hand, in the vicinity of the outer peripheral portion of the contact surface between the mesh bodies 41a and 41b, an aromatic agent 6 such as cypress chips is added for imparting an aroma to the air taken into the room from the outside.

Next, the operation of the above embodiment will be described.

By operating the suction fan 5, the outdoor air is taken into the ventilation hole 2 and flows through the mesh bodies 41a and 41b in the filter device 4 which is provided outside the ventilation cylinder 3. And the air that enters from the minute holes 44 of the frame 42 and flows through the mesh bodies 41a and 41b.

In the air flowing through the filter unit 41, suspended particles such as dust are removed.

On the other hand, the fragrance component of the fragrance agent 6 such as cypress chips is scattered in the air flowing through the frame 42, merges with the air entering from the mesh body 41a side, and is taken into the room.

Here, since the air resistance of the filter device 4 is large, a fast air flow is formed in the filter portion 41, so that even a fragrance such as cypress, which has a low scattering property, contains a large amount of aroma components. It scatters, and as a result, clean and aromatic air flows into the room.

Further, the scattering amount of the fragrance component decreases with time, but on the other hand, since the fragrance 6 is gradually sucked and moves to the vicinity of the center of the filter portion 41 with time, the mess body Since the fragrance is added to the air flowing from the side of 41a, the appropriate fragrance effect can be maintained for a long period of time.

According to such an embodiment, even when the outdoor air is accompanied by a foul odor or an offensive odor, the offensive odor or offensive odor taken into the room is hidden by the fragrance, so that there is little discomfort.

Further, since a fast air flow is formed in the filter device 4 by the suction fan 5, it is possible to select a wide range of fragrances including those having low scattering properties, and for example, natural materials such as cypress may be used. You can enjoy the natural scent directly indoors.

Note that the structure of the filter device 4 is not limited to the structure shown in FIG. 2, but as shown in FIG. 4, for example, a planar surface impregnated with an aromatic agent made of a liquid chemical product. The absorbent body 61 or the like is fixed to the entire surface or a part of the filter portion 41, or is interposed between two mesh bodies, or liquid fragrance is applied to the filter device. And so on.

Further, as the filter section 41, one having a gas adsorbing function such as black ink or activated carbon may be incorporated, which is preferable because the malodorous component of the outside air can be removed.

The present embodiment is applied to an outside air intake type air cleaning device which is attached to a wall portion that separates the room from the outside, but the present invention has the inlet and the outlet located on the indoor side, respectively. It can also be applied to an indoor circulation type air cleaning device in which a circulation fan and a filter device are provided in the ventilation path.

Further, when the outdoor is outdoors, an air intake port 71, for example, as shown by a chain line in FIG. 1, is provided on the outdoor side of the ventilation hole 2 so that the outdoor wind does not directly hit the ventilation hole 2. It is preferable to attach a cover 7 provided to the wall portion 1, and for example, an opening may be provided on the indoor side of the ventilation hole 2 so that air having an aroma attached thereto can be taken into the room at an appropriate amount when necessary. It is preferable to attach a cover 21 provided with shutter means whose area can be adjusted so as to engage with the peripheral edge of the collar portion 31, and further, to suck in air according to the layout of furniture in the room. At the outlet of the fan 5, it is preferable to provide a wind direction regulating means 8 as shown in FIG. .

Instead of providing the suction fan 5 as in the embodiment of FIG. 1, it is also possible to forcibly take in the outdoor air by exhausting the indoor air with an indoor ventilation fan or the like provided in the room.

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

[0036]

[Effect of the device]

 According to the present invention, since the filter device to which the fragrance is attached is provided in the air passage, the room is filled with clean and fragrant air.

In addition, since the air itself taken into the room has a fragrance, and the air with the fragrance diffuses into the room, it is not necessary to separately place a fragrance in the room, and therefore the fragrance does not exist in the room. It is not necessary to secure a space for installing the agent. Furthermore, since the fragrance is attached to the filter device, it is not necessary to separately secure a dedicated container for storing the fragrance, a dedicated installation space, and a dedicated mounting member in a narrow air passage. The upper maintenance can be performed with the fragrance and the filter device at once.
