Description

  The present invention relates to a building.

Some buildings have an attached garage in which vehicles are stored. In such an attached garage, there is a concern about deterioration of the environment due to exhaust gas discharged from the vehicle. Therefore, it has been proposed to install a ventilation fan in the garage that discharges exhaust gas in the garage to the outside of the garage (see, for example, Patent Document 1). This improves the environment in the garage.
Japanese Patent Laid-Open No. 10-160213

  However, dust accumulation occurs at a boundary portion between the garage floor and the garage inner wall, a boundary portion between the garage inner wall and a shelf installed with this as a back surface, and the like. In this way, the boundary portion where dust accumulation is likely to occur is also a place that is difficult to clean. Such a problem cannot be solved by the technique described in Patent Document 1 in which a ventilation fan is simply installed in the garage. Such a problem can also occur in a building space other than the attached garage.

  The main object of the present invention is to provide a building that suppresses the accumulation of dust at the boundary portion of the space in the building.

  The present invention employs the following means in order to solve the above problems.

  In the first invention, a boundary portion formed by the first surface facing upward and the second surface facing sideways is provided in a predetermined space in the building, and airflow is generated in the space in the building. And an airflow generation device capable of causing the airflow to reach the boundary portion.

  According to the first aspect of the present invention, it is possible to generate an airflow extending over the boundary portion in the building space by the airflow generator. Thereby, dust can be removed from the boundary portion, and by extension, dust can be prevented from accumulating at the boundary portion.

  In the second invention, the air flow generator includes an air supply portion that sends air outside the space in the building into the space in the building from an air supply opening in the space in the building, and an air outlet that opens in the space in the building. And an exhaust part that exhausts the air in the space in the building to the outside of the space in the building, and the air supply to the space in the building by the air supply part and the exhaust part generates an air flow that reaches the boundary part.

  According to the second aspect of the present invention, an air flow having a large flow velocity reaching the boundary portion can be generated in the building space portion by supplying and exhausting the space portion in the building by the air supply portion and the exhaust portion. Thereby, dust can be effectively removed from the boundary portion. Moreover, the airflow which flows from an air supply port to an exhaust port can be generated by the air supply and exhaust of the space part in a building by an air supply part and an exhaust part. As a result, the dust removed from the boundary portion can be put on the airflow and discharged out of the space in the building from the exhaust port.

  In the 1st invention and the 2nd invention, it is possible that the dust removed from the boundary part floats in the space part in a building. Therefore, in the third invention, the exhaust port is opened below the air supply port in the space in the building.

  According to the third aspect of the invention, it is possible to generate a downward airflow that flows from the air supply port to the exhaust port that opens downward from the air supply port. Thereby, it can suppress that the dust removed from the boundary part floats in a building.

  In the vicinity of the air supply port, an air flow having a high flow rate is generated by the air sent into the space in the building by the air supply unit. In the vicinity of the exhaust port, an air flow having a large flow velocity is generated by the air exhausted from the space inside the building by the exhaust unit. Therefore, it is desirable to provide at least one of the air supply port and the exhaust port in the vicinity of the boundary as in the fourth invention. Thereby, an air flow with a large flow velocity can be generated at the boundary portion, and dust can be more effectively removed from the boundary portion.

  Much of the dust floating in the space in the building is thought to accumulate at the boundary. Therefore, in the fifth invention, when it is determined that the dust contained in the air in the space in the building is detected and the detected dust is equal to or greater than a certain level, the driving of the airflow generation device is started. Control means.

  According to the fifth aspect of the present invention, when the dust contained in the air exceeds a certain level, an air flow is automatically generated in the space in the building. Thereby, before the dust which is floating in the space part in a building collects in a boundary part, those dusts can be discharged | emitted out of the space part in a building from an exhaust port with the air in the space part in a building.

  Some buildings have an attached garage in which vehicles are stored. In the attached garage, dust accumulation is likely to occur at the boundary due to dust entering the garage from the outside of the garage through the vehicle entrance and / or dust generated when getting on and off from the vehicle. Therefore, in the sixth invention, in the first to fifth inventions, the space in the building is used as an attached garage, and an airflow extending to the boundary in the attached garage is generated in the attached garage. Thereby, it can suppress that dust accumulates in the boundary part in an attached garage.

  In the seventh invention, the airflow generation device further generates an airflow on the body surface of the vehicle stopped in the attached garage. Thereby, the dust adhering to the vehicle body can be removed.

  When water droplets adhere to the vehicle, dust is adsorbed on the water droplets adhering to the vehicle, and the dust adsorbed on the water droplets remains as dirt on the vehicle. Therefore, in the eighth invention, the determination means for determining the presence or degree of water droplet adhesion to the vehicle parked in the attached garage, and the determination means determine that there is water droplet adhesion to the vehicle or that there is more than a certain amount of water droplet adhesion. Control means for generating an air current on the body surface of the vehicle that is stopped in the attached garage by the air current generating device.

  According to the eighth aspect of the present invention, when even a small amount of water droplets are attached to the vehicle, or when more than a certain amount of water droplets are attached to the vehicle, an air flow is generated on the body surface of the vehicle. Thereby, water droplets adhering to the vehicle can be removed. As a method for removing the water droplets, it is conceivable that the water droplets adhering to the vehicle are removed by drying with an air stream, or the water droplets adhering to the vehicle are blown off by the air stream. In this case, by removing the water droplets adhering to the vehicle at an early stage, it is possible to suppress the adhesion of dust to the vehicle and to suppress the contamination of the vehicle body surface due to the adhering dust.

  In 9th invention, the airflow generator has a dehumidification part which dehumidifies air. According to the ninth aspect, it is possible to generate an airflow on the body surface of the vehicle by the air dehumidified by the dehumidifying unit. In this case, water droplets adhering to the vehicle can be dried and removed early.

  Hereinafter, an embodiment will be described with reference to the drawings.

Dust tends to accumulate in the “part”.

  Therefore, the building 10 is provided with a dust removal system that removes dust accumulated in the corners 31 to 34 in the garage 12. As shown in FIG. 2, in this dust removal system, the air supply device 40 feeds outdoor air into the garage 12, and the exhaust device 50 discharges the air in the garage 12 to the outdoors, so An air flow is generated in 34. And dust is removed from the corner parts 31-34 by this airflow.

  Specifically, as shown in FIG. 1, the ceiling material 17 of the garage 12 is provided with a plurality of first air supply ports 41 that open in the vertical direction so as to communicate with the inside of the garage 12 and the back of the ceiling. In the present embodiment, the first air supply port 41 is formed on one surface of the ceiling material 17.

  Near the corner 34 between the wall 15 and the top plate 26, a plurality of second air supply ports 42 are provided. In the present embodiment, the second air inlet 42 is formed in a portion slightly above the top plate 26 of the wall 15 and opens in the garage 12 in the horizontal direction. A third air supply opening 43 that opens in the garage 12 in the horizontal direction is formed in a portion on the ceiling side of the wall 14.

  As shown in FIG. 2, the building 10 is provided with a main body 45 of the air supply device 40. In the present embodiment, the air supply device main body 45 is provided on the ceiling behind the garage 12 (on the ceiling material 17). Thereby, the space in the garage 12 can be used more effectively than when the air supply device main body 45 is provided in the garage 12. The air supply device main body 45 includes an air supply fan 46 and a dehumidifying unit 47. An air supply duct 48 and an air supply duct 49 are connected to the air supply device main body 45. The air supply duct 48 extends from the outdoors to the air supply device main body 45. The air supply duct 49 extends from the air supply device main body 45 to the air supply ports 41 to 43 and opens into the garage 12. In this case, by the rotation of the air supply fan 46, outdoor air is sent to the air supply device main body 45 via the air supply duct 48, dried in the dehumidifying unit 47, and the dried air is supplied to the air supply duct 45. 49 is fed into the garage 12 through the air supply ports 41 to 43.

  A plurality of first exhaust ports 51 are provided in the vicinity of the corner 31 between the soil material 18 and the wall 14 (see FIG. 1). In the present embodiment, the first exhaust port 51 is formed in a portion slightly above the dirt member 18 of the wall 14 and opens in the garage 12 in the horizontal direction. A plurality of second exhaust ports 52 are provided at a portion (hereinafter referred to as “corner portion 32 a”) on the front side of the garage 12 (side of the entrance / exit 13) in the corner portion 32 between the soil material 18 and the wall 15. A plurality of third exhaust ports 53 are provided in a portion of the corner 32 on the back side (the wall 16 side) of the garage 12 (hereinafter referred to as “corner portion 32b”). A plurality of fourth exhaust ports 54 are provided in a portion of the corner portion 32 surrounded by the side plate 28 of the shelf 25 (hereinafter referred to as “corner portion 32 c”). In the present embodiment, the exhaust ports 52 to 54 are formed in a portion slightly above the dirt member 18 of the wall 15 and open in the garage 12 in the horizontal direction. Moreover, the exhaust ports 52-54 are arrange | positioned 1 each at the both ends of the garage 12 near side and the back | inner side of the corners 32a-32c corresponding to each exhaust port.

  The building 10 is provided with a main body 55 of the exhaust device 50. In the present embodiment, the exhaust device main body 55 is provided under the floor of the living room 11. Thereby, the space in the garage 12 can be used more effectively than when the exhaust device body 55 is provided in the garage 12. The exhaust device body 55 has an exhaust fan 56. An exhaust duct 58 and an exhaust duct 59 are connected to the exhaust device body 55. The exhaust duct 58 extends from the exhaust ports 51 to 54 to the exhaust device main body 55. The exhaust duct 59 extends from the exhaust device body 55 to the outdoors. In this case, due to the rotation of the exhaust fan 56, the air in the garage 12 is discharged to the outdoors from the exhaust ports 51 to 54 through the exhaust ducts 58 and 59.

  As shown in FIG. 1, when the air supply device 40 and the exhaust device 50 are operated, an airflow extending to the corners 31 to 34 is generated in the garage 12.

  Specifically, when the air supply device 40 is operated, outdoor air is sent into the garage 12 from the first air supply port 41 formed in the ceiling member 17. This air flows downward toward the dirt side. On the other hand, when the exhaust device 50 is operated, the air in the garage 12 is discharged to the outdoors from the exhaust ports 51 to 54. Thereby, a downdraft flowing from the first air supply port 41 to the exhaust ports 51 to 54 is generated in the garage 12. This descending airflow flows downward from the first air supply port 41 toward the soil side. Thereafter, the downward airflow is blocked by the dirt material 18 along the path, and flows toward the walls 14 to 16 along the dirt surface. Furthermore, the descending airflow is then blocked by the walls 14 to 16 along the path, and flows toward the exhaust ports 51 to 54 along the corners 31 to 33. As described above, when the air supply device 40 and the exhaust device 50 are operated, a downdraft flowing from the first air supply port 41 through the corners 31 to 33 to the exhaust ports 51 to 54 is generated.

  When the air supply device 40 is operated, outdoor air is also sent into the garage 12 from the second air supply port 42. This air flows through the corner 34 to the center of the garage 12. Thereafter, the air flows on the descending airflow by the air fed into the garage 12 from the first air supply port 41 and is discharged from the fourth exhaust port 54 to the outdoors. As a result, a downward airflow that flows from the second air supply port 42 through the corner 34 to the fourth exhaust port 54 is generated in the garage 12.

  When the air supply device 40 is operated, outdoor air is also sent into the garage 12 from the third air supply port 43. The air flows on the descending airflow caused by the air sent from the first air supply port 41 into the garage 12 and is discharged from the first exhaust port 51 to the outside. As a result, a downdraft flowing from the third air supply port 43 to the first exhaust port 51 is generated in the garage 12.

  By generating an air flow in the garage 12 in such a manner as to reach the corners 31 to 34, dust can be removed from these corners 31 to 34.

  Here, the first air supply port 41 is formed on one surface of the ceiling material 17 as described above. That is, the first air supply port 41 is also formed in the ceiling material 17 on the parking area 29. Thereby, when the vehicle is parked in the parking area 29, a downdraft caused by the air sent from the first air supply port 41 into the garage 12 flows along the body surface of the vehicle. Thereby, the dust adhering to the body surface of the vehicle stopped in the garage 12 can be removed.

  On the other hand, dust that has been removed from the corners 34 is included in the descending airflow generated by the air fed into the garage 12 from the second air supply port 42. Therefore, when this airflow hits the body of a vehicle parked in the garage 12, dust may adhere to the body surface of the vehicle. Therefore, in the present embodiment, the first air inlet 41 and the second air supply are prevented so that the descending airflow caused by the air sent into the garage 12 from the second air inlet 42 does not pass through the parking area 29 in the garage 12. The arrangement | positioning of the opening | mouth 42 and the flow velocity of the air sent into the garage 12 from the 1st supply port 41 and the 2nd supply port 42 are set. Thereby, adhesion of the dust to the body surface of the vehicle stopped in the garage 12 can be suppressed.

  As shown in FIG. 2, various sensors (open / close sensor 60, human sensor 61, dust sensor 62, temperature sensor 63, and humidity sensor 64) are provided in garage 12 (see FIG. 2). The open / close sensor 60 is a sensor that detects opening / closing of the entrance / exit 13 by the shutter curtain 22, and is provided in the shutter case 21 in this embodiment. The human sensor 61 is a sensor that detects the presence or absence of a person using a predetermined area in the garage 12 as a detection area. In the present embodiment, the human detection sensor 61 is provided outside the shutter case 21 with the detection area facing the back side of the garage 12. ing. The dust sensor 62 is a sensor that detects the concentration of dust contained in the air in the garage 12, and is provided on the garage 12 side of the ceiling material 17 in this embodiment. The temperature sensor 63 and the humidity sensor 64 are sensors that detect the temperature and humidity in the garage 12, respectively, and are provided on the garage 12 side of the ceiling material 17 in this embodiment. These various sensors are electrically connected to the building controller 65. The building controller 65 is installed in the living room 11, for example.

  Next, the electrical configuration of the dust removal system will be described with reference to FIG.

  The building controller 65 is mainly composed of a known microcomputer including a CPU, a memory, and the like, and controls each part of the building 10. In particular, in the present embodiment, the building controller 65 is based on detection signals from various sensors (open / close sensor 60, human sensor 61, dust sensor 62, temperature sensor 63, and humidity sensor 64). The air supply fan 46, the dehumidifying unit 47, and the exhaust fan 56) are configured to be controllable.

  Here, the control of the dust removal system performed by the building controller 65 will be described in detail. When the doorway 13 of the garage 12 is closed by the shutter device 20, the corners 31 to 34 and It becomes possible to efficiently generate an air flow having a large flow velocity in the parking area 29.

  That is, when the entrance / exit 13 of the garage 12 is opened, outdoor air flows into the garage 12 from the entrance / exit 13 as well as the supply ports 41 to 43. The air in the garage 12 flows out to the outside. As a result, the airflow flowing from the air supply ports 41 to 43 to the exhaust ports 51 to 54, that is, the flow velocity of the airflow flowing through the corners 31 to 34 and the parking area 29 becomes relatively small. On the other hand, when the entrance / exit 13 of the garage 12 is closed, the garage 12 becomes a substantially closed space, and thus the airflow flowing from the air supply ports 41 to 43 to the exhaust ports 51 to 54, that is, the corner 31. The flow velocity of the airflow flowing through the parking area 29 and the parking area 29 is relatively increased.

  Therefore, the controller 65 determines opening / closing of the entrance / exit 13 by the shutter device 20 based on the detection signal of the opening / closing sensor 60, and operates the dust removal system when the entrance / exit 13 is closed by the shutter device 20. In this way, by generating an air flow having a large flow velocity at the corners 31 to 34 and the parking area 29, the dust at the corners 31 to 34 and the dust attached to the body surface of the vehicle can be effectively removed.

  When the dust removal system is in operation, it is conceivable that more dust floats in the garage 12 than when the dust removal system is stopped. Therefore, when the resident of the building 10 is in the garage 12, operating the dust removal system may cause discomfort to the resident.

  Therefore, the controller 65 determines the presence or absence of a person in the garage 12 based on the detection signal of the human sensor 61, and operates the dust removal system when there is no person in the garage 12. Thereby, the dust adhering to the corner parts 31-34 and the vehicle body surface can be removed, without giving discomfort to the occupant of the building 10.

  Most of the dust floating in the garage 12 is thought to eventually collect in the corners 31-34. Therefore, the controller 65 determines the level of dust contained in the air in the garage 12 based on the detection signal of the dust sensor 62, and operates the dust removal system when it is determined that the concentration is above a certain value. Let In this case, the dust floating in the garage 12 is discharged to the outdoors from the exhaust ports 51 to 54 together with the air in the garage 12 before the dust accumulates in the corners 31 to 34. Thereby, it can suppress that dust accumulates in the corner parts 31-34.

  If water droplets adhere to the vehicle body surface stopped in the garage 12, dust is adsorbed to the water droplets adhered to the vehicle body surface, and the dust adsorbed to the water droplets becomes spotted pattern surface dirt. Remain in. Therefore, it is desirable to remove water droplets adhering to the vehicle body surface at an early stage. Therefore, the controller 65 determines whether or not water droplets adhere to the vehicle body surface stopped in the garage 12 based on the detection signals of the temperature sensor 63 and the humidity sensor 64, and the water droplets adhere to the vehicle body surface. If it is determined that the dust removal system is present, the dust removal system is operated.

  Here, the air sent into the garage 12 by the air supply device 40 is dehumidified by the dehumidifying unit 47. Further, as described above, the downdraft caused by the air sent into the garage 12 from the first air supply port 41 flows along the body surface of the vehicle stopped in the parking area 29. Therefore, by operating the dust removal system when water droplets are attached to the vehicle body surface, the water droplets attached to the vehicle body surface can be quickly dried and removed. Thereby, the adhesion of dust to the body surface of the vehicle stopped in the garage 12 can be suppressed, and contamination of the body surface of the vehicle due to the dust can be suppressed.

  Next, dust removal processing using the dust removal system will be described with reference to FIG. FIG. 4 is a flowchart showing the flow of the dust removal program. This dust removal program is executed at predetermined intervals by the building controller 65.

In the dust removal process shown in FIG. 4, the dust removal system is used when both of the following conditions (1) and (2) are satisfied and any of the following conditions (3) to (5) is satisfied: Is now in operation.
(1) The entrance / exit 13 of the garage 12 is closed by the shutter device 20.
(2) There are no people in the garage 12.
(3) The dust removal system has not been operated for a predetermined time or more.
(4) The concentration of dust contained in the air in the garage 12 is a certain value or more.
(5) Water droplets adhere to the vehicle body surface.

  Specifically, in step S <b> 10, the controller 65 determines opening / closing of the entrance / exit 13 by the shutter device 20 based on a detection signal of the opening / closing sensor 60. If the controller 65 determines that the entrance / exit 13 is closed, the process proceeds to step S11. If the controller 65 determines that the entrance / exit 13 is opened, the execution of the current program ends.

  In step S <b> 11, the controller 65 determines the presence or absence of a person in the garage 12 based on the detection signal from the human sensor 61. If the controller 65 determines that there is no person in the garage 12, the process proceeds to step S12. If the controller 65 determines that there is a person in the garage 12, the execution of the current program ends.

  In step S12, the controller 65 determines whether or not the stop time of the dust removal system is equal to or longer than a predetermined time. If the controller 65 determines that the dust removal system stop time is equal to or longer than the predetermined time, the controller 65 proceeds to step S15. If the controller 65 determines that the dust removal system stop time is shorter than the predetermined time, the controller 65 proceeds to step S13. Here, the predetermined time defines a cycle for forcibly operating the dust removal system. It is desirable that the predetermined time can be variably set to a desired time by a resident of the building 10.

  In step S <b> 13, the controller 65 determines whether the concentration of dust contained in the air in the garage 12 is equal to or higher than a certain value based on the detection signal of the dust sensor 62. If the controller 65 determines that the concentration of dust contained in the air in the garage 12 is greater than or equal to a predetermined value, the controller 65 proceeds to the process of step S15, and the concentration of dust contained in the air in the garage 12 is smaller than the predetermined value. If determined, the process proceeds to step S14.

  In step S <b> 14, the controller 65 determines whether or not water droplets adhere to the body surface of the vehicle stopped in the garage 12 based on the detection signals of the temperature sensor 63 and the humidity sensor 64. Specifically, the controller 65 calculates the dew point temperature in the garage 12 based on the detection signals of the temperature sensor 63 and the humidity sensor 64, and estimates that the temperature of the body of the vehicle stored in the garage 12 is lower than the dew point temperature. In such a case, it is determined that water droplets are generated on the body surface of the vehicle that has entered. In this case, the vehicle body temperature can be estimated based on the season, date, date and outside temperature. If the controller 65 determines that water droplets are attached to the vehicle, the process proceeds to step S15. If the controller 65 determines that water droplets are not attached to the body surface of the vehicle, the execution of the current program ends.

  In step S15, the controller 65 operates the dust removal system. That is, the controller 65 operates the air supply fan 46, the exhaust fan 56, and the dehumidifying unit 47. Then, after operating the dust removal system for a predetermined time (see step S16), the controller 65 stops the operation of the dust removal system (see step S17).

  With the above configuration, the following advantageous effects can be obtained.

  By supplying and exhausting the garage 12 by the air supply device 40 and the exhaust device 50, an airflow flowing from the air supply ports 41 to 43 to the exhaust ports 51 to 54 through the corners 31 to 34 and the parking area 29 was generated. Thereby, the dust at the corners 31 to 34 and the dust attached to the body surface of the vehicle can be removed, and the accumulation of dust at the corners 31 to 34 and the contamination of the body surface of the vehicle with the dust are suppressed. Can do. Moreover, the dust removed from the corner parts 31-34 and the vehicle body surface can be carried on the said airflow, and can be discharged | emitted from the exhaust ports 51-54 outdoors.

  The flow velocity of the airflow generated by the air supply / exhaust of the garage 12 is larger than the flow velocity of the airflow generated by either the air supply / exhaust of the garage 12. Thereby, the dust of the corner parts 31-34 and the dust adhering to the body surface of a vehicle can be removed effectively.

  A downward airflow flowing through the corners 31 to 34 and the parking area 29 was generated in the garage 12. Thereby, it can suppress that the dust removed from the corner parts 31-34 and the body surface of a vehicle floats in the garage 12. FIG.

  In the vicinity of the corner portion 34, the corner portion 31, and the corner portions 32a to 32c, an air supply port 42, an exhaust port 51, and exhaust ports 52 to 54 are provided, respectively. In this case, an air flow having a large flow velocity is generated in the corner portion 34 when outdoor air is sent into the garage 12 by the air supply device 40. At the corner 31 and the corners 32a to 32c, air in the garage 12 is discharged to the outdoors by the exhaust device 50, thereby generating an air flow with a high flow velocity. Thereby, dust can be effectively removed from the corner portion 34, the corner portion 31, and the corner portions 32a to 32c.

  The dust removal system was activated when the dust removal system had not been operated for a predetermined time. In this case, the dust removal system is operated approximately periodically, and airflows flowing through the corners 31 to 34 and the parking area 29 are generated approximately periodically. As a result, the dust at the corners 31 to 34 and the dust attached to the body surface of the vehicle are periodically removed, so that the dust accumulates at the corners 31 to 34 and the surface of the vehicle body is contaminated by the dust. Can be suppressed.

  The dust removal system was operated when the concentration of dust contained in the air in the garage 12 exceeded a predetermined value. In this case, when a lot of dust is floating in the garage 12, an airflow flowing from the air supply ports 41 to 43 to the exhaust ports 51 to 54 is automatically generated in the garage 12. Thereby, before the dust floating in the garage 12 collects in the corner parts 31-34, those dust can be discharged | emitted with the air in the garage 12 from the exhaust ports 51-54 outdoors.

  The dust removal system was activated when it was determined that water droplets had adhered to the body surface of the vehicle parked in the garage 12. In this case, when water droplets are attached to the body surface of the vehicle, an airflow flowing through the parking area 29 is generated. Thereby, water droplets adhering to the body surface of the vehicle can be dried and removed at an early stage, and dust adhesion to the vehicle body surface and dirt due to dust on the vehicle body surface can be suppressed.

  The dust removal system is operated when the entrance / exit 13 of the garage 12 is closed. In other words, the dust removal system is not operated when the doorway 13 of the garage 12 is open. Here, as described above, when the entrance / exit 13 of the garage 12 is closed, the air flow having a larger flow velocity at the corners 31 to 34 and the parking area 29 than when the entrance / exit 13 of the garage 12 is opened. Can be generated efficiently. Therefore, when the entrance / exit 13 of the garage 12 is opened, the dust removal system is operated to generate air currents in the corners 31 to 34 and the parking area 29, whereby the power consumption of the air supply device 40 and the exhaust device 50 is increased. The dust at the corners 31 to 34 and the dust attached to the vehicle body surface can be removed.

  The dust removal system was activated when there were no people in the garage 12. In other words, when there is a person in the garage 12, the dust removal system is not operated. Here, as described above, it is conceivable that more dust floats in the garage 12 when the dust removal system is in operation than when the dust removal system is stopped. Therefore, when there is no person in the garage 12, the dust removal system is operated to generate airflow in the corners 31 to 34 and the parking area 29, so that the occupants of the building 10 do not feel uncomfortable. The dust on the parts 31 to 34 and the dust attached to the body surface of the vehicle can be removed.

  Note that the present invention is not limited to the embodiment described above, and can be implemented, for example, in the form shown as another example below.

  In the above embodiment, air currents are generated in the corners 31 to 34 and the parking area 29 by supplying and exhausting the garage 12 by the air supply device 40 and the exhaust device 50.

  However, the present invention is not limited thereto, and an air flow may be generated in the corners 31 to 34 and the parking area 29 by either one of the supply and exhaust of the garage 12. In this case, the flow velocity of the airflow generated in the corners 31 to 34 and the parking area 29 is smaller than the flow velocity of the airflow generated by the air supply / exhaust of the garage 12, but dust removal is performed on either the air supply device 40 or the exhaust device 50. By configuring the system, the dust removal system can be reduced in size and the manufacturing cost can be reduced.

  Further, an air flow may be generated in the corners 31 to 34 and the parking area 29 by circulating the air in the garage 12. In this case, the air supply device 40 and the exhaust device 50 are not required as a dust removal system. For example, an air flow can be generated in the corners 31 to 34 and the parking area 29 by providing a blower in the garage 12. Thereby, it is possible to simplify the installation process and improve the installation flexibility of the dust removal system.

  In the above embodiment, a downdraft is generated in the garage 12. However, the present invention is not limited to this, and an airflow that flows in the vicinity of the corner in the garage 12 along the corner may be generated in the garage 12. Thereby, dust can be effectively removed from the corner. For example, as shown in FIG. 5, air supply ports 71 to 74 are provided in the vicinity of the ends of the corners 32 a to 32 c and 34 on the back side (wall 16 side) of the garage 12, and the garages 12 of the corners 32 a to 32 c and 34 are provided. You may provide the exhaust ports 81-84 in the edge part vicinity of the near side (entrance / entrance 13 side). In this case, an airflow is generated that flows in the vicinity of the corners 32 a to 32 c and 34 along the corners 32 a to 32 c and 34. These airflows flow from one end of each corner 32a to 32c, 34 on the rear side of the garage 12 to the other end on the front side of the garage 12. Thereby, dust can be wiped out from the corners 32a to 32c, 34.

  Alternatively, an airflow that flows across the garage 12 and passes through the corners of the garage 12 may be generated. For example, as shown in FIG. 6, the first air supply port 41 of the above embodiment may not be provided, and an airflow flowing diagonally from the second air supply port 42 to the first exhaust port 51 may be generated in the garage 12. . By this air flow, dust can be removed from the corners 31 and 34.

  The outdoor air may be sent into the garage 12 from one air supply port in a plurality of directions by the air supply device 40. For example, as shown in FIG. 7, outdoor air may be sent into the garage 12 from one air supply port 75 toward a plurality of exhaust ports 85 to 87. Specifically, for example, louvers that can be set in different directions from each other may be provided at the air supply port. Thereby, the number of the air inlets provided in the garage 12 can be reduced.

  -The flow of the air flow generated in the garage 12 may be variably set manually or automatically. In this case, even if the corner or the parking area changes due to a layout change in the garage 12 or the like, the dust at the corner or the dust attached to the body surface of the vehicle is removed by resetting the airflow. be able to.

  -It is not necessary to provide the dehumidification part 47 in the air supply apparatus 40. FIG. By causing an air flow by dehumidified air to flow along the vehicle body surface as in the above embodiment, water droplets attached to the vehicle can be dried quickly. Therefore, although it is desirable to provide the dehumidifying part 47 in the air supply apparatus 40, by omitting the dehumidifying part 47, the air supply apparatus 40 can be reduced in size and the manufacturing cost can be reduced.

  In the above embodiment, the water droplets adhering to the vehicle body surface are dried and removed by flowing an air flow along the vehicle body surface. However, water droplets adhering to the vehicle body surface may be blown off and removed by applying an air flow having a large flow velocity to the vehicle body surface.

  A dust removal system that generates an airflow for removing dust from corners 31 to 34 and a dust removal system that generates an airflow for drying and removing water droplets attached to the body surface of the vehicle are individually provided. It may be provided. Moreover, you may generate an airflow only in the corner parts 31-34. In this case, dust attached to the vehicle body surface cannot be removed, but the dust removal system can be reduced in size and the manufacturing cost can be reduced.

  In the above embodiment, whether or not water droplets adhere to the vehicle body surface is determined based on whether or not the estimated value of the temperature of the vehicle body is equal to or less than the calculated value of the dew point temperature in the garage 12. However, the present invention is not limited to this, and when a vehicle enters the garage 12 during rainy weather or snowy weather, it may be determined that water droplets are attached to the body surface of the vehicle.

  In the above embodiment, the space in the building that is the object of the dust removal process is the space in the garage 12, but the space in the building may be, for example, the space in the living room 11.
