Detailed Description of the Invention [Industrial applications]

 The present invention relates to an air cleaning device installed in a building.

[Prior art and its problems]

Innumerable bacteria live in the room. For example, it is said that about 1 million ticks live in a room of 4.5 guts. On the other hand, when cypress is used for the floor board, it has been observed that the mites are reduced by a factor of 10,000 and the number becomes about 100. This is because the bactericidal action of β-tsuyapurisin or the like contained in cypress significantly reduces mites. However, because cypress is an extremely high-grade interior material, it cannot be used extensively except in special buildings. A wooden house that uses a lot of wood such as cypress can not only reduce ticks, but can also make use of the unique properties of trees to achieve a comfortable living environment. Tree
This is because it has a property of absorbing moisture when the humidity is high, and releasing the moisture when it is dried. However, even if the current house is a wooden house, the amount of wood used is decreasing and the amount of new building materials used is increasing. Therefore, even in a wooden house, it is not possible to make good use of the characteristics of trees and make the indoor environment comfortable. In addition, the building timber used in the current home is
For decoration, most of them are coated on the surface, or synthetic resin is pressed into the surface for use. The respiratory action of the wood in this state is stopped by the surface treatment layer. Therefore, the characteristic of wood is that the moisture absorption-humidification action is extremely small, and the characteristics of wood are killed before use. Furthermore, the board materials that can be used for the interior wall boards are limited to those with beautiful wood grain and high quality. The cheap ones have a poor surface pattern and cannot be used for decoration. This is because the tree for interior is used as a surface finishing material for the room. Therefore, even though wood can be used in high-class houses, it cannot be used as an interior finishing material in inexpensive buildings. In addition, a building that uses wood as an interior material is limited by the interior design. If a Western-style building is decorated with wood, it will be difficult to achieve a total balance with the surroundings. For such buildings, it is inevitable to use new building materials of various colors and patterns. The present inventor set out to develop the present invention and investigated similar publications in order to make use of the features of the old wooden house in all kinds of buildings today. As a result, we found a wood filler (Japanese Patent Laid-Open No. 61-176734) used as a wall filler for filling the hollow portion of the wall. The filler cements wood chips and spongy inorganic particles with cement. Cement wraps around the wood chips to prevent burning. This filler is applied on site by the following method. The wood waste, the inorganic particles and the cement are mixed. The weight of the cement is about half that of the wood waste and the granules, and the cement is half the weight of the granules. The mixture is poured through an inlet provided at the top of the wall and is distributed by gravity and fluidity throughout the wall. However, this filler can be used as a heat insulating material, soundproofing material, and fireproofing material for wall surfaces, but since wood waste is covered with cement, it is necessary to effectively utilize the hygroscopicity of the wood to control the indoor humidity. I can't. In addition, a method of waterproofing a heat insulating material using chips is disclosed in
It is disclosed in Japanese Patent No. 236950. In this method, mortar with chips mixed with pearlite is used as the base material for the roof. This method uses chips made from small pieces of wood, but because mortar is used together and it is used for roofs, it is not possible to control indoor humidity with chips. The present inventor succeeded in developing a wooden house having ideal characteristics as a result of repeating various experiments and trial and error on the wall structure of the building that can be used for all kinds of houses by making the most of the characteristics of wood. In this building, as shown in FIG. 4, wood pieces 4 are filled in the middle chamber between the outer wall material 1 and the inner wall material 2. The hollow portion 3 was filled with innumerable pieces of wood 4 obtained by cutting wood into small pieces, for example, chips or wood cut into small blocks. Wood piece 4 filled in the hollow part 3
Were filled with voids so that air could pass between them. The piece of wood 4 was made to expose the wood to the surface so as to absorb moisture from the surface and release the absorbed moisture, and not to be covered with a non-permeable film. An air circulation path was provided so as to pass through the inner wall member 2 and communicate with the interior of the room so that air would flow between the hollow portion 3 of the wall and the room. A forced air blowing fan 10 was provided so as to be connected to the hollow portion 3 so as to sufficiently blow the indoor air to the wood piece 4 of the hollow portion 3. The forced draft fan 10 is preferably in the ceiling and the hollow portion 3.
And, provided in at least one of the floor. In the building having this structure, the humidity of the indoor air can be adjusted by the wood piece 4 by passing the room air between the wood pieces 4 filled in the hollow portion of the wall. It has the feature that indoor air can be filtered and clarified. Buildings with this structure can realize a comfortable indoor environment that is superior to traditional wooden houses. However, it is difficult to apply it to existing buildings. This is because the wood pieces are filled in the wall. In a building of this structure, by using cypress chips or the like for wood pieces, it is possible to give a pleasant scent to the air circulating in the room. However, in the building of this structure, since the wood pieces are filled in the wall, the scent of cypress and the like decreases as it is used for a long time. Once the scent has decreased, the pieces of wood cannot be replaced, so that the pieces of wood cannot give a pleasant scent to the room thereafter. The present invention was further developed with the object of solving this drawback, and an important object of the present invention is to sterilize indoor air for a long period of time or to make the indoor air have a pleasant scent. In addition, it is possible to provide an air purifying device for a building, which is capable of refining indoor air.

[Means for solving conventional problems]

The building air cleaning device of the present invention has the following configuration. (A) The air cleaning device includes a casing 6, a piece of wood 4,
The wood piece 4 is provided with a chemical liquid supply means for supplying the chemical liquid to the wood piece 4, and a forced air blowing fan 10. (B) The casing 6 has a hollow shape, and an air inlet 7 and an air outlet 8 are opened in the hollow portion so that room air can be circulated. (C) The indoor air is sucked in through the suction port 7, passes through the hollow portion, and then is recirculated from the discharge port 8 into the room, and the suction port 7, the discharge port 8 and the hollow portion of the casing 6, and the forced blowing fan. 10 and 10 are connected in series. (D) The wood piece 4 is obtained by cutting wood into small pieces, and the wood piece 4 is filled in the hollow portion of the casing 6. Piece of wood 4
For example, chips or wood cut into small blocks can be used. (E) The wood piece 4 filled in the hollow portion 3 is filled in a state in which a gap is formed therebetween. (F) The wood piece 4 has wood exposed on its surface so as to absorb the chemical solution from the surface and release the absorbed chemical solution. (G) The inlet 7 and the outlet 8 opened in the casing 6 are communicated with the room. (H) The forced air blowing fan 10 is configured to pass indoor air between the pieces of wood 4, the air is filtered by the pieces of wood 4, and the chemical liquid contained therein is vaporized and discharged into the air.

[Operation effect]

In the air purifying apparatus with a building according to the present invention, the hollow portion of the casing is filled with wood pieces. In the air purifier of this structure, the wood pieces filled in the casing clarify the air to adjust the humidity. Therefore, it is not necessary to put a tree on the wall as in a conventional wooden house, even though the tree finely adjusts the indoor air to adjust the humidity. Therefore, even though the pattern of the wall of the house is not specified as the wood grain, the indoor humidity control function and the air refining action which are more excellent than those of the conventional wooden construction are realized. This is because the wood pieces absorb a lot of water when the humidity is high, release the water when they are dry, and remove dust contained in the air when passing between the wood pieces. Is. The wood piece in the hollow part can increase the amount of moisture absorption, as compared to the plate-like wood stretched on the wall, the small piece of wood can significantly increase the surface area per weight and increase the total water absorption. Because. The wood piece having a large surface area has a large contact area with the air, makes it possible to smoothly absorb and release moisture from the indoor air, and efficiently filter and remove dust contained in the air. The surface area of a wooden board stretched over the wall of a conventional wooden house is limited by the area of the wall. Even if unevenness is provided on the surface, the surface area cannot be increased so much. However, the wood piece of the present invention can have a large surface area that is incomparable with the area of the wall surface. The total amount of surface area of the piece of wood can be increased by making the piece of wood smaller. In addition, the building of the present invention does not require time-consuming processing in order to increase the total surface area of the wood pieces whose humidity is adjusted. All you have to do is cut a piece of wood into small pieces. This is because the pieces of wood are stored in an invisible place. For this reason, it is not necessary to cut the wood piece with a beautiful outer diameter. Therefore, wood processing is extremely simple. For example, it can be easily and easily processed into small pieces using an apparatus for processing wood into chips. Therefore, there is a feature that the processing cost can be remarkably reduced. Further, the wood piece used for the wall structure of the building of the present invention can have a significantly low material cost. Almost all kinds of raw wood can be used for processing the wood pieces, and the shape is not limited. Therefore, it is possible to use extremely inexpensive waste wood and thinned wood. Wood pieces, which can reduce the raw material cost and the labor required for processing, can be mass-produced at extremely low cost, and also have an excellent feature that the ability to control the humidity of natural wood can be improved. Further, the air purifying apparatus for a building of the present invention is installed indoors or outdoors of the building, and is filled with a piece of wood in the casing to clarify the indoor air and adjust the humidity. Available. In other words, there is a feature that the living environment inside the room can be improved and the existing building can be easily installed without restricting the design of the interior decoration. Therefore, by using new building materials that match well with the total design of the interior of the wallboard, the living environment can be "comfortable living" that is superior to the old wooden construction. It has features that can be used for both new construction and existing housing. The wooden interior materials stretched over the walls of conventional wooden houses are
Expensive in proportion to the thickness. Cost limits the thickness of the plate that can be placed on the wall. Normally, the wall material for interior use is made of a plate material of 3 mm or less. Therefore, even if a plate material capable of absorbing moisture is used for the wall plate, the total amount of plate material cannot be increased so much. In contrast, the air purifying device of the present invention uses extremely inexpensive pieces of wood to condition and clarify indoor air. For this reason, use a large amount of wood chips,
It is inexpensive and has features that can improve the humidity control ability and the air refining ability. Furthermore, in the building of the present invention, the indoor air is forcibly circulated in the hollow portion by the forced ventilation fan. The amount of air that is forced to circulate is compared to the amount of natural convection circulation,
You can do a lot more. In addition, this makes it possible to increase the amount of air circulated even if the wood pieces are densely packed in the hollow portion and it is difficult for air to pass through. Therefore, a large amount of wood pieces can be packed and filled in the hollow portion, the amount of wood pieces with respect to the volume of the hollow portion can be increased, and the humidity adjusting ability can be improved. Further, the amount of air circulated between the room and the hollow portion can be controlled by the amount of air blown by the forced air blowing fan. When a large-sized forced air fan with a large amount of air is used, the amount of air circulation increases, and conversely, when a small forced air fan is used, the amount of air circulation can be reduced. Also, if you want to control the operation of the forced air fan,
It is also possible to adjust the blowing condition. That is, room air can be circulated in the hollow portion only when necessary. Furthermore, a remarkable feature of the air cleaning device of the present invention is that the chemical solution can be supplied to the wood pieces over a long period of time. The air passing through the impregnated wood piece supplied with the chemical solution is sterilized by the chemical solution contained in the wood piece, or added with a comfortable scent, or the malodor is deodorized and circulated in the room. For example, by adding the scent of cypress to the piece of wood, the scent of cypress can be made to float in the room, and when the scent becomes less, the chemical liquid supply means can add the chemical liquid of the scent to the piece of wood again. Further, as the chemical liquid, a deodorant such as Anico (registered trademark) or a chemical liquid that kills various bacteria in the air can be used instead of an aromatic agent that gives a pleasant scent. Therefore, the air purifying apparatus for a building according to the present invention has an advantage that it can be used extremely comfortably and that the indoor air can be made comfortable without affecting the indoor design for installing the apparatus.

[Preferred embodiment]

Embodiments of the present invention will be described below with reference to the drawings. However, the examples shown below are examples of an air purifying apparatus for a building for embodying the technical idea of the present invention, and the air purifying apparatus of the present invention is composed of materials, shapes, and structures of components. , The arrangement is not specified in the structure below. The air purifying apparatus of the present invention has various modifications within the scope of the claims. Further, in this specification, for easier understanding of the claims, the numbers corresponding to the members shown in the embodiments are added to the members shown in the claims. However, the members described in the claims are not limited to the members shown in the embodiments. The air cleaning device for a building shown in FIG.
The wood piece 4, a chemical liquid supply means for supplying a chemical liquid to the wood piece 4, and a forced air blower 10 for circulating indoor air between the wood pieces 4. The air cleaning device shown in the figure is fixed to the wall surface. The casing 6 has the following structure. The casing 6 has a hollow portion 3 in which the wood pieces 4 are filled.
Is provided. The casing 6 communicates with the hollow portion 3.
An air inlet 7 is opened in the lower part and an outlet 8 is opened in the upper part. The air sucked from the suction port 7 is discharged from the discharge port 8. That is, the casing 6 sucks air from the suction port 7 and discharges the sucked air to the room from the discharge port 8. Therefore, the casing 6 has a structure in which the sucked air does not leak on the way. An innumerable piece of wood 4 is built in the hollow portion 3 of the casing 6. The volume of the hollow portion 3 of the casing 6 is determined by the amount of the timber pieces 4 to be filled in consideration of the size of the room. Room 6 ~
In the case of 10 tablets, the volume of the hollow portion 3 is usually 10 to 200 l, preferably 30 to 100 l, and the wood piece 4 is filled therein. The casing 6 is made into a slender tubular shape so as to have a large internal volume with a small installation area. The wood piece 4 filled in the hollow portion 3 has the following configuration. The piece of wood 4 can be any kind of wood, for example, cypress,
Small pieces of wood such as cedar, pine, fir, beech, zelkova, hemlock, chestnut, cherry, oak, cod, and persimmon can be used. The wood piece 4 made of cypress or cousin sterilizes the air passing there, and also has an insect repellent effect. The easiest way to cut wood into pieces is to cut it like chips for pulp. However, the present invention does not specify the shape of the wood piece 4 as a chip shape. For example, it is also possible to process wood into small blocks, or to crush wood into small pieces. The wood pieces 4 can be packed in the hollow portion 3 in a disassembled state, but the wood piece 4 can be put in a breathable case to remove the hollow portion 3.
Can also be filled. As the breathable case, a case made of corrugated cardboard or synthetic resin with holes can be used. When the wood piece 4 is put in a case and filled in the hollow portion 3, there is a feature that the hollow portion 3 can be easily filled. In addition, when the wood pieces 4 are packed in a case, a solid fragrance or the like can be put therein together. The wood pieces 4 filled in the hollow portion 3 are filled in such a manner that a space is formed between the wood pieces 4 so that air is circulated therein. The gap between the wood pieces 4 can be adjusted by the shape of the wood pieces 4. The smaller the wood piece 4 is, the narrower the void becomes, and it becomes difficult for air to pass through. On the contrary, the larger the wood piece 4 becomes, the larger the void becomes, and the air easily passes through. The small piece of wood 4 has a high air filtering efficiency and can filter air more clearly. The large pieces of wood 4 allow air to smoothly pass therethrough and are unlikely to be clogged with dust. The size of the wood piece 4 is usually 0 in consideration of the filtration rate of air.
It is adjusted to a range of 1 square mm to 100 cubic cm, preferably 1 to 20 cubic cm. Further, when the hollow portion 3 is filled with the case, the porosity of the wood piece 4 can be adjusted in the filled state. By the way, the wood piece 4 has a function of adjusting humidity together with air filtration. Therefore, the wood piece 4 absorbs moisture from the surface when the humidity in the air is high, and releases the absorbed moisture when the humidity in the air is low to adjust the humidity of the indoor air. Further, the wood piece 4 is impregnated with the supplied chemical liquid, and vaporizes the impregnated chemical liquid to release it into the air. Therefore,
The piece of wood 4 needs to expose wood to the surface so that it can absorb and remove moisture from the surface and can absorb and release the chemical liquid. It is not good to cover the surface with a non-breathable film because the absorption of the drug solution is lost. Although the present invention is characterized in that the hollow portion 3 of the air cleaning device is filled with wood pieces, ceramic particles, paper, or the like can also be filled with the wood pieces as an extender. Further, in the air cleaning device of the present invention, the casing 6 mounted on the building is filled with the wood pieces 4. Therefore, the wood piece 4 can be replaced with a cartridge type. This air purifying apparatus fills the cartridge 9 with the wood pieces 4,
The wood piece 4 is filled in the hollow portion 3 of the casing 6 via the cartridge 9. The cartridge 9 is made of breathable material so that the filled wood pieces 4 can be ventilated. For example, the cartridge 9 can be manufactured at low cost by using a cardboard box having numerous vent holes. The cartridge 9 is replaceably mounted on the casing 6. Therefore, the casing 6 that houses the cartridge 9
The front panel 22 is detachably attached to the casing body. When the front panel 22 is removed, the cartridge 9 is detached and attached, and the front panel 22 is closed in a use state, the casing 6 is airtightly closed. As described above, the air cleaning device that stores the wood pieces 4 through the cartridge 9 has a feature that the wood pieces 4 can be replaced after being used for a certain period of time. For example, if the wood pieces 4 are used for several months and dust in the air is clogged, the wood pieces 4 can be replaced by the cartridge 9. The chemical liquid supply means has the following structure. The chemical liquid supply means shown in FIG. 1 includes a chemical liquid tank 11, a chemical liquid supply valve 12, a chemical liquid sensor 14, and a control circuit 15. The chemical liquid tank 11 has a volume for storing a chemical liquid of 4 to 20 l, for example. The chemical liquid tank 11 has an open top surface or is detachably housed in the casing 6 so that the chemical liquid can be replenished therein. As the chemical liquid to be supplied to the chemical liquid tank 11, for example, an aromatic agent that gives off a scent of wood, a deodorant agent that collects or deodorizes a bad odor in the air, a bactericidal agent that kills various bacteria in the air, and the like can be used. When opened, the chemical liquid supply valve 12 supplies the chemical liquid in the chemical liquid tank 11 to the wood piece 4. The chemical liquid supply valve 12 is opened and closed by detecting the chemical liquid content of the wood piece 4. That is, the chemical liquid supply valve 12 is opened only when the chemical liquid content of the wood piece 4 is low. The chemical liquid sensor 14 detects the amount of chemical liquid contained in the wood piece 4. When the amount of the chemical liquid contained in the piece of wood 4 decreases, this is detected and a signal is sent to the control circuit. Further, when the chemical solution is supplied to the wood piece 4, this is detected and a signal is sent to the control circuit. The chemical sensor 14 is arranged in the middle or bottom of the wood piece 4. The chemical solution sensor 14 detects the chemical solution content rate of the wood piece 4 by, for example, electric resistance. The control circuit 15 processes the input signal from the chemical solution sensor 14 to control the open / closed state of the chemical solution supply valve 12 to the next state. That is, the control circuit 15 opens the chemical liquid supply valve 12 only when the chemical liquid content of the wood piece 4 is lower than the set value. The chemical liquid supply means shown in FIG. 1 controls the chemical liquid supply valve 12 to control the chemical liquid supply amount to the wood piece 4. As shown by the chain line in FIG. 1, a string material 21 for transferring the chemical liquid by the capillary phenomenon.
The chemical solution in the chemical solution tank 11 can be supplied to the wood piece 4. As the string material 21, a string-shaped one can be used in which a myriad of fine fibers are collected. The string 21 has one end guided to the chemical liquid tank 11 and the other end guided to the inside of the wood piece 4. The chemical liquid supply means of this structure uses a capillarity
Since 21 supplies the chemical solution to the wood piece 4, the chemical solution supply means can be made extremely simple. This is because the chemical solution supply valve, the chemical solution sensor, and the control circuit can be omitted. Further, as shown in FIG. 2, instead of the chemical liquid supply valve 12,
It is also possible to control the amount of water supplied to the wood piece 4 with the chemical liquid pump 16. The chemical pump 16 has a suction side on the chemical tank 11,
The discharge side is connected to the piece of wood 4. The chemical liquid supply means for replenishing the wood piece 4 from the chemical liquid tank 11 using the chemical liquid pump 16 arranges the chemical liquid tank 11 at the bottom portion and supplies the chemical liquid to the wood piece 4 at a position higher than the chemical liquid tank 11. It is possible to Therefore, this chemical liquid supply means has a feature that the installation location of the chemical liquid tank 11 is not restricted. This invention does not specify the chemical liquid supply means to the structure shown in FIG. As the chemical liquid supply means, any mechanism that can replenish the wood piece 4 can be adopted. The simplest chemical liquid supply means is a chemical liquid supply port provided on the upper part of the piece of wood. This chemical solution supply means can supply the chemical solution to the wood piece 4 from the supply port by using, for example, a tea jar or a Joro. The supply amount of the chemical liquid is determined to be an optimum value in consideration of the chemical liquid amount contained in the wood piece 4. By the way, as shown in FIG. 1, if a gas-permeable gutter 17 is provided below the wood piece 4, the wood piece 4 can be supplied with a chemical solution having a maximum content or more. This is because the chemical liquid falling from the piece of wood can be received by the gutter 17, drained, or stored in a drain tank (not shown). The chemical solution stored in the drain tank can be replenished to the wood piece again by the chemical solution pump. The forced blower fan 10 built into the casing 6
It has the following configuration. The forced air blower 10 sucks the air in the room, passes the air through the wood piece 4, and then returns the air to the room. Therefore, the forced ventilation fan 10 is connected in series to the suction port 7, the discharge port 8 and the hollow portion 3 of the wood piece 4. In the air purifying apparatus shown in FIG. 1, the forced air blower fan 10 is provided on the air discharge side. The forced ventilation fan 10 forcibly sucks the air in the room through the wood piece 4 and the suction port 7, passes the wood piece 4, and circulates the filtered air from the exhaust port 8 into the room. The forced ventilation fan 10 does not necessarily have to be provided on the discharge side. Although not shown, it may be provided on the suction side.
Further, the forced ventilation fan 10 can be provided outside the casing 6. A small fan, for example, a small motor-driven fan of several watts to several tens of watts can be used as the forced draft fan 10. The forced draft fan 10 is normally operated continuously for 24 hours. However, the operating time of the forced draft fan 10 can be controlled by a timer. In this case, the operation is preferably stopped at midnight. Further, it is possible to provide an operation switch of the forced draft fan 10 in the room so that the forced draft fan 10 can be operated only when necessary. As shown in FIG. 1, the air-purifying device provided indoors has a feature that it can be easily attached to a new or existing house without modifying the house. However, as shown in FIG. 2, the air cleaning device can be installed behind the ceiling. In this case, the chemical liquid tank 11 is arranged indoors, and the water in the chemical liquid tank 11 is supplied to the wood piece 4 by the chemical liquid pump 16. Since this structure can effectively use the space above the ceiling, the air purifier has a feature that it does not occupy the indoor space. The air purifying apparatus shown in FIG. 2 has an air intake port 7 and an air exhaust port 8 on the ceiling plate. The air inlet 7 and the air outlet 8 are closed by a breathable ceiling plate like a louver. The louver of the suction port 7 is attached to the ceiling plate via a hinge so that it can be opened and closed. In the air purifying device having this structure, the ceiling plate 18 provided with the suction port 7 is opened to replace the wood piece 4 housed in the cartridge 9. The air that has passed from the suction port 7 between the wood pieces 4 in the cartridge 9 is forcibly recirculated into the room from the louver of the discharge port 8 by the forced ventilation fan 10. Therefore, the forced blower fan 10 is built in between the cartridge 9 and the discharge port 8. In the air cleaning apparatus of FIG. 2, a chemical liquid supply pipe 20 as a chemical liquid supply means is provided above the wood piece 4. Chemical supply pipe
The chemical liquid supply valve 12, which is opened and closed by the control circuit 15, is connected to the valve 20. Like the chemical liquid supply valve 12 of FIG. 1, the chemical liquid supply valve 12 is opened only when the content of the chemical liquid in the wood piece 4 is low. Furthermore, the air cleaning device shown in FIG. 3 is installed outside the wall, that is, outdoors. The air purifying device is connected to the room through a suction port 7 and a discharge port 8 which penetrate the wall. The casing 6 has a built-in forced air fan 10 at the top,
The hollow portion 3 is provided in the lower part. The hollow portion 3 is filled with a piece of wood 4 via a cartridge 9. The hollow portion 3 of the casing 6 is provided with a door 19 on the outside so that the cartridge 9 can be replaced. Open the door 19 and replace the cartridge 9. Hollow part 3 with door 19 closed
Is hermetically closed. Since the casing 6 is installed outdoors in the air cleaner of this structure, the volume of the hollow portion 3 can be significantly increased. The air purifying device in which the hollow portion 3 has a large volume and is filled with a large amount of wood pieces 4 can cleanly filter the air and can improve the air filtering ability. The air cleaning device shown in FIGS. 1 and 3 can also be used as a circulator for indoor air by reversing the forced air blowing fan 10. That is, when the winter is cold, the warm air in the ceiling is forced to circulate under the floor to warm the floor, which is easily cooled, and when the summer is hot, the cool air on the floor is circulated to the ceiling to cool the room. There is a feature that can be done. When the forced blower fan 10 is rotated in the reverse direction, the suction port 7 and the discharge port 8 are reversed so that the suction port 7 becomes the discharge port 8 and the discharge port 8 becomes the suction port 7.
Becomes Further, although not shown, the air cleaning device of the present invention can be installed under the floor.
