Description

  The present invention relates to a building that is constituted by a garage in which a vehicle is stored or that includes a part of the garage.

When a vehicle engine is operated in a garage of a garage building or a garage building, the garage may be filled with exhaust gas from the vehicle. Then, the ventilation apparatus in a garage provided with the ventilation fan which ventilates the inside of a garage is proposed (refer patent document 1). According to this ventilator, it is possible to suppress the exhaust gas concentration in the garage from exceeding a certain level.
Japanese Patent Laid-Open No. 10-160213

  However, in the ventilation apparatus described in Patent Document 1, the ventilation fan does not operate unless the exhaust gas concentration in the garage increases to a predetermined level or higher. Further, even after the ventilation fan is activated, a certain time is required until the exhaust gas concentration sufficiently decreases. Thus, it is hard to say that the environment in the garage is sufficient.

  The present invention has been made to solve the above-described problems, and has as its main object to provide a building that maintains a good garage environment.

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

  Here, when the engine is started in the garage, for example, when the vehicle parked in the garage is warmed up, the exhaust gas concentration in the garage may increase rapidly. In this regard, according to the first invention, ventilation can be started before the exhaust gas concentration increases by operating the ventilator in association with engine start. Thereby, the garage environment can be kept good.

  In the second invention, the control means operates the ventilator before starting the engine of the vehicle in the garage. By starting ventilation before starting the engine in this way, the exhaust gas of the vehicle can be efficiently discharged to the outside from the beginning of the engine start. Thereby, the environment in the garage can be kept better.

  In 3rd invention, a control means operates a ventilator according to engine starting operation of the starting device which starts the engine of the vehicle in a garage. According to the third aspect of the invention, since ventilation is automatically started in accordance with the engine start operation of the vehicle, it is possible to maintain a good garage environment without making the building user aware of the ventilation in the garage. it can.

  In the fourth aspect of the invention, the ventilator generates a ventilation flow that flows from the ceiling side to the soil side on the far side in the vehicle entrance direction of the garage, and discharges the exhaust gas of the vehicle to the outdoors on the ventilation flow.

  According to the fourth aspect of the invention, it is possible to promote the ventilation in the vehicle approach direction depth side in the garage. Here, the exhaust gas of the vehicle is generally discharged from the rear part of the vehicle. Therefore, when the vehicle moves backward into the garage, the exhaust gas of the vehicle is discharged to the rear side in the vehicle entry direction in the garage. Therefore, by promoting ventilation on the far side in the vehicle approach direction in the garage as described above, the exhaust gas of the vehicle can be efficiently discharged outdoors, especially when the vehicle is moved backward into the garage. In many cases, the exhaust gas of the vehicle is discharged from the vehicle to the vicinity of the dirt surface of the garage. Therefore, by generating a ventilation flow that flows from the ceiling side to the soil side as described above, before the exhaust gas of the vehicle diffuses into the garage, the exhaust gas is placed on the ventilation flow near the soil surface and discharged to the outside. Can do.

  In the fifth aspect of the invention, the ventilator includes an air supply unit that supplies outside air taken in indoors from an air supply port provided in the garage to the vehicle entry direction back side in the garage, and a vehicle entry direction back side in the garage. And an exhaust part for exhausting the inside air from an exhaust port provided in the garage to the outside.

  According to the fifth aspect of the invention, the outside air is supplied to the back side in the vehicle approach direction in the garage by the air supply unit, and the inside air in the back direction of the vehicle in the garage is discharged to the outdoors by the exhaust unit. As a result, a ventilation flow is generated in the garage that flows from the outside through the air supply port to the back side in the vehicle entry direction in the garage and flows out from the back side of the vehicle entry direction in the garage through the exhaust port to the outside. Can do.

  In a sixth aspect of the invention, the exhaust section includes an exhaust passage extending from the rear side of the garage in the vehicle entry direction to the exhaust port side, and an exhaust fan for sending the inside air on the rear side of the garage in the vehicle entry direction to the exhaust port side via the exhaust passage. have. In this case, by operating (rotating) the exhaust fan, the inside air at the rear side in the vehicle entrance direction of the garage can be sent to the exhaust port side via the exhaust passage and discharged from the exhaust port to the outside. In particular, in the sixth aspect of the invention, the exhaust passage is provided below the dirt surface of the garage, and is opened to the dirt surface on the back side in the vehicle entrance direction of the garage. In this case, a ventilation flow passing through the vicinity of the soil surface can be generated in the garage on the back side of the garage in the vehicle approach direction. Thereby, the exhaust gas of the vehicle discharged in the vicinity of the soil surface can be efficiently exhausted outdoors by being put on the ventilation flow.

  In the seventh aspect of the invention, the air supply unit includes an air supply passage extending from the air supply port side to the rear side in the vehicle entrance direction of the garage, and outside air taken indoors from the air supply port through the air supply passage in the vehicle entrance direction of the garage. A blower for supplying air to the back side. In this case, by operating (rotating) the air supply blower, the inside air from the back of the garage in the vehicle entrance direction is taken into the vehicle entrance direction of the garage via the air supply passage. Can send. In particular, in the seventh invention, the air supply passage is provided on the ceiling side of the garage. Thereby, the ventilation flow which flows into the dirt side from the ceiling side of a garage can be generated in the vehicle approach direction back side of a garage.

  The eighth invention further includes an electric shutter device having a shutter curtain to which a plurality of slats are connected and a drive unit for driving each slat, and opening and closing the vehicle entrance / exit of the garage by the shutter curtain. Then, the control means controls the driving of each slat by the drive unit to close the slats in the middle region of the shutter curtain and open the slats in the upper region and the lower region to supply the shutter curtain. A vent and an exhaust are formed.

  According to the eighth aspect of the invention, since the air supply port and the exhaust port are formed in the shutter curtain, it is not necessary to provide an opening dedicated to the air supply port or an opening dedicated to the exhaust port in the garage.

  In a ninth aspect of the invention, a vehicle detection device that detects the presence or absence of a vehicle in the garage is further provided, and the control unit operates or stops the ventilation device based on the presence or absence of the vehicle detected by the vehicle detection device. Here, when there is a vehicle in the garage, new exhaust gas may be discharged from the vehicle. On the other hand, when there is no vehicle in the garage, new exhaust gas is not discharged from the vehicle into the garage. Therefore, by setting the presence or absence of the vehicle as one of the control parameters of the ventilation device, the ventilation device can be appropriately controlled according to the probability of new exhaust gas generation.

  In the tenth invention, an exhaust gas concentration detection device for detecting the exhaust gas concentration in the garage is further provided, and the control means stops the ventilation device based on the detection result of the exhaust gas concentration by the exhaust gas concentration detection device. According to the ninth aspect of the invention, the ventilation in the garage by the ventilation device is continued until the exhaust gas concentration decreases to a predetermined level. Thereby, the environment in a garage can be kept above a certain level.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In this embodiment, the garage is ventilated by a ventilation system in a building with a garage.

  First, a schematic configuration of a building with a garage according to the present embodiment will be described with reference to FIGS. 1A is a front view of a building with a garage, and FIG. 1B is a cross-sectional view of the building with a garage.

  As shown in FIG. 1, a building 10 is a building with a garage that includes at least a garage 11 on the first floor and a living room 12 on the second floor. The garage 11 has an entrance / exit 17 for the vehicle 50, and the periphery excluding the entrance / exit 17 is partitioned by a wall. The garage 11 is provided with a shutter device 30 that opens and closes the doorway 17 of the vehicle 50. The ceiling material 18 that forms the ceiling surface of the garage 11 is disposed below the floor material 19 of the second floor part with a predetermined interval, and a predetermined space is provided between the ceiling material 18 and the floor material 19 of the second floor part. Is formed. In addition, the floor surface of the garage 11 is formed with an earthen material 20 such as by placing concrete.

  The shutter device 30 includes a shutter case 31 mounted indoors, for example, above the doorway 17, and a shutter curtain 32 that is housed while being wound around the shutter case 31. The entrance / exit 17 is closed when the shutter curtain 32 is pulled out (lowered) from the shutter case 31, and the entrance / exit 17 is opened when the shutter curtain 32 is wound (raised) into the shutter case 31. It has become. In a state where the doorway 17 is closed by the shutter curtain 32, the garage 11 is a generally closed space.

  FIG. 2 is a diagram showing a detailed configuration of the shutter device 30. 2, illustration of guide rails and shutter cases 31 (see FIG. 1) provided at both left and right ends of the shutter device 30 is omitted for convenience of explanation. In the shutter device 30, the shutter curtain 32 is configured by connecting a large number of slats 33 in the vertical direction (short direction of the slats 33). That is, a part of the slats 33 that are vertically adjacent to each other are engaged with each other, so that a large number of slats 33 are integrated to form the shutter curtain 32. In addition, since the structure which engages between many slats 33 is known, description is abbreviate | omitted here.

  A winding drum 34 is connected to the uppermost slat among the many slats 33, and a drum driving unit 35 is connected to the winding drum 34. The drum driving unit 35 is configured by an electric motor or the like, and the winding drum 34 is rotationally driven in either the forward or reverse direction by the drum driving unit 35, whereby the shutter curtain 32 (multiple connected slats 33). Is wound or withdrawn.

  On the side of the shutter curtain 32, open / close guide mechanisms 36 to 38 for adjusting the angle of each slat 33 (hereinafter referred to as “slat angle”) are provided. The open / close guide mechanisms 36 to 38 have an engagement link portion 39 that can be engaged with a part of the slat 33, and the slat angle can be adjusted by the engagement link portion 39. The open / close guide mechanisms 36 to 38 are connected to a slat drive unit 40 composed of an electric motor or the like, and each of the open / close guide mechanisms 36 to 38 is driven by the slat drive unit 40. The slats 33 can be tilted simultaneously in units of the upper region 32a, intermediate region 32b, and lower region 32c of the shutter curtain 32. The shutter device 30 outputs a signal indicating the slat angle of each of the upper region 32a, the intermediate region 32b, and the lower region 32c of the shutter curtain 32.

  The garage 11 is provided with a ventilation device for ventilating the inside of the garage 11. The ventilation device includes an air supply duct 13, an air supply fan 14, an exhaust duct 15, an exhaust fan 16, and the like.

  In detail, between the ceiling material 18 of the garage 11 and the flooring 19 of the second floor portion, the garage 11 in the vehicle entry direction front side (entrance 17 side) to the garage 11 in the vehicle entry direction back side (opposite the entrance 17). A tubular air supply duct 13 extending to the side) is provided. Since the air supply duct 13 is disposed above the ceiling member 18, the internal space of the garage 11 is not narrowed. Both ends of the air supply duct 13 are opened downward at the end of the ceiling member 18 on the doorway 17 side and the end on the back side when viewed from there. An air supply fan 14 is provided in the air supply duct 13. The air supply fan 14 is arranged so that an air flow from the front side of the garage 11 toward the back side is generated in the air supply passage in the air supply duct 13. Therefore, by driving the air supply fan 14, air is taken into the air supply duct 13 from the vicinity of the upper part of the entrance / exit 17, and the air that has entered the air supply duct 13 is discharged from the upper back side of the garage 11. The air supply fan 14 outputs a signal indicating the rotation speed.

  A tubular exhaust duct 15 extending from the back side of the garage 11 to the front side is provided below the surface of the dirt material 20 of the garage 11. The exhaust duct 15 is installed, for example, by placing concrete so that the exhaust duct 15 is filled after the exhaust duct 15 is positioned in advance when the earthen material 20 is formed of concrete. The Since the exhaust duct 15 is disposed below the surface of the dirt member 20 as described above, the internal space of the garage 11 is not narrowed. Both ends of the exhaust duct 15 are opened upward at the end of the interstitial material 20 on the doorway 17 side and the end on the back side when viewed from there. An exhaust fan 16 is provided at the exhaust inlet in the exhaust duct 15. The exhaust fan 16 is arranged so that an air flow from the rear side of the garage 11 toward the front side is generated in the exhaust passage in the exhaust duct 15. Therefore, by driving the exhaust fan 16, air is taken into the exhaust duct 15 from the lower back side of the garage 11, and the air that has entered the exhaust duct 15 is discharged from the vicinity of the lower part of the entrance / exit 17 of the garage 11. The exhaust fan 16 outputs a signal indicating the rotational speed.

  The air supply duct 13 and the air supply fan 14 correspond to an “air supply part”, and the exhaust duct 15 and the exhaust fan 16 correspond to an “exhaust part”. Further, the air supply fan 14 corresponds to an “air supply blower”, and the exhaust fan 16 corresponds to an “exhaust blower”. The air supply blower and the exhaust blower may be blowers.

  In the garage 11 described above, in the shutter device 30, the upper region 32 a and the lower region 32 c of the shutter curtain 32 are opened and the upper region 32 a and the lower region 32 c of the shutter curtain 32 are opened. An air supply port and an exhaust port can be formed respectively. In the ventilator, by operating (rotating) the air supply fan 14 and the exhaust fan 16, the interior of the garage 11 passes through the air supply duct 13 from the air supply port formed in the upper region 32 a of the shutter curtain 32. It is possible to generate a ventilation flow in the garage 11 that flows to the side and flows from the back side of the garage 11 to the exhaust port formed in the lower region 32 c of the shutter curtain 32 through the exhaust duct 15.

  The ventilation flow by the ventilation device flows in the vicinity of the muffler 51 of the vehicle 50 stopped in the garage 11. Specifically, as shown in FIG. 3A, when the vehicle 50 is stopped in the garage 11 so that the muffler 51 of the vehicle 50 is located on the back side of the garage 11, on the back side of the garage 11. A ventilation flow that flows from an air supply outlet of the air supply duct 13 toward an exhaust inlet of the exhaust duct 15 flows in the vicinity of the muffler 51 of the vehicle 50. On the other hand, as shown in FIG. 3B, when the vehicle 50 is stopped in the garage 11 so that the muffler 51 of the vehicle 50 is located on the front side of the garage 11, Thus, a ventilation flow that flows from the exhaust outlet of the exhaust duct 15 toward the lower region 32 c of the shutter curtain 32 flows in the vicinity of the muffler 51 of the vehicle 50. Then, the exhaust gas discharged from the muffler 51 is dragged by the ventilation flow and gets on the ventilation flow. That is, when the ventilation flow acts directly on the outlet of the muffler 51, the exhaust gas directly rides on the ventilation flow. In addition, when there is a ventilation flow at a location slightly away from the outlet of the muffler 51, the exhaust gas moves toward the ventilation flow due to a negative pressure around the ventilation flow, so that the exhaust gas quickly moves into the ventilation flow. Will ride. Thereby, even when the vehicle 50 is stored in the garage 11 either backward or forward, the exhaust gas of the vehicle 50 can be efficiently discharged to the outside by being put on the ventilation flow.

  An exhaust gas concentration sensor 23 is attached to the ceiling material 18 of the garage 11. The exhaust gas concentration sensor 23 outputs a detection signal corresponding to the exhaust gas concentration in the garage 11. A vehicle detection sensor 24 is attached to the dirt member 20 of the garage 11. The vehicle detection sensor 24 outputs a detection signal indicating whether or not there is a vehicle in the garage 11.

  For example, a building controller 25 is installed in the living room 12. The building controller 25 is mainly composed of a known microcomputer provided with a CPU, a memory, and the like, and controls each part of the building 10. In particular, in the present embodiment, the building controller 25 is configured to be able to control the ventilation device of the garage 11.

  The building controller 25 is connected to the shutter device 30, the air supply fan 14, the exhaust fan 16, the exhaust gas concentration sensor 23, and the vehicle detection sensor 24 described above. The controller 25 is wirelessly connected to a remote controller 26 for the controller and an ECU 52 mounted on the vehicle 50. Here, the remote controller 26 is a wireless terminal that transmits various request signals corresponding to the operation of the user of the building 10 to the building controller 25. In particular, in the present embodiment, the remote controller 26 is configured to be able to transmit an engine start request signal (a signal for requesting engine start of the vehicle 50). The remote controller 26 corresponds to a “starter”. The ECU 52 is a controller for a vehicle mainly composed of a known microcomputer provided with a CPU, a memory, and the like. In particular, in the present embodiment, the ECU 52 is configured to be able to start the engine of the vehicle 50 in response to an engine start command signal from the building controller 25 (a signal that the controller 25 instructs the ECU 52 to start the engine).

  Based on the detection signals of the exhaust gas concentration sensor 23 and the vehicle detection sensor 24 and the request signal of the remote control 26, the building controller 25 is connected to the drum drive unit 35, the slat drive unit 40, the air supply fan 14, the exhaust fan 16 and the ECU 52. To control.

  Next, the ventilation process in the garage 11 will be described with reference to FIGS. FIG. 4 is a flowchart showing the flow of the ventilation control program. This program is stored in the memory of the building controller 25 and is executed by the CPU of the building controller 25 at a predetermined cycle. FIG. 5 is a diagram showing the operation of the ventilation device by this ventilation processing. In FIG. 5, (a) shows the state in the garage 11 before the start of the ventilation process, and (b) shows the state in the garage 11 during execution of the ventilation process.

  In step S <b> 10 shown in FIG. 4, the controller 25 determines whether there is an engine start request for the vehicle 50. Specifically, the controller 25 detects the presence or absence of an engine start request signal transmitted from the remote controller 26, and determines the presence or absence of an engine start request based on the detection result. When it is determined that there is a request for starting the engine of the vehicle 50, the controller 25 proceeds to the process of step S11. When it is determined that there is no request for starting the engine of the vehicle 50, the execution of the current program is terminated.

  In step S11, the controller 25 operates the ventilator. Specifically, the controller 25 controls the slat drive unit 40 of the shutter device 30 to close the intermediate region 32b of the shutter curtain 32 and open the upper region 32a and the lower region 32c of the shutter curtain 32 ( (Refer FIG.5 (b)). The controller 25 operates the air supply fan 14 and the exhaust fan 16 (see FIG. 5B). As a result, a ventilation flow indicated by a one-dot chain line in FIG. 5B is generated in the garage 11.

  In subsequent step S12, the controller 25 determines whether the shutter device 30 and the ventilation device are normal or abnormal. Specifically, the controller 25 determines that the intermediate region 32b of the shutter curtain 32 is closed based on the output signal indicating the slat angle of the shutter device 30, and that the upper region 32a and the lower region 32c of the shutter curtain 32 are in the closed state. Make sure it is open. Further, the controller 25 confirms that the fans 14 and 16 are rotating at a predetermined rotation speed or higher based on output signals indicating the rotation speeds of the supply fan 14 and the exhaust fan 16. . Then, the controller 25 determines that the shutter device 30 and the ventilation device are normal when all of these can be confirmed, and if any of these cannot be confirmed, the controller 25 determines either the shutter device 30 or the ventilation device. It is determined that there is an abnormality.

  If it is determined in step S12 that the ventilation device is normal, the controller 25 waits for a ventilation flow to be generated in the garage 11 (see step S13), and the vehicle 50 stopped in the garage 11 The engine is started (see step S14). Specifically, the controller 25 outputs an engine start command signal to the ECU 52 after a predetermined time (for example, 5 seconds) has elapsed. Thereby, the engine is started by the ECU 52 in the vehicle 50. As a result, the exhaust gas indicated by the two-dot chain line in FIG. 5B is discharged from the vehicle 50 into the garage 11.

  Thereafter, the controller 25 detects the exhaust gas concentration in the garage 11 every elapse of a predetermined time (for example, 10 seconds) until a predetermined condition is satisfied (see steps S15 to S17). And the controller 25 will progress to the process of step S18, when predetermined conditions are satisfied. Here, the predetermined condition is that the exhaust gas concentration in the garage 11 has become equal to or less than a predetermined value, and secondly that the vehicle 50 has left the vehicle or that the engine of the vehicle 50 has been stopped.

  Here, the processing in steps S15 to S17 will be described in detail. The controller 25 waits for the elapse of a predetermined time (see step S15), and determines whether or not the exhaust gas concentration in the garage 11 has become a predetermined value or less. The determination is made based on the detection signal 23 (see step S16). If the controller 25 determines that the exhaust gas concentration in the garage 11 is less than or equal to the predetermined value, the controller 25 proceeds to the process of step S17. If the controller 25 determines that the exhaust gas concentration in the garage 11 is greater than the predetermined value, the step is performed. The process returns to S15. In step S <b> 17, the controller 25 determines whether or not the vehicle 50 has been delivered based on the detection signal of the vehicle detection sensor 24. Further, the controller 25 determines whether or not an operation for stopping the engine of the vehicle 50 is performed on the remote controller 26. And the controller 25 progresses to the process of step S18, when it determines with the vehicle 50 having left the vehicle or the engine of the vehicle 50 being stopped, and returns to the process of step S15 in the case other than that.

  In step S18, the controller 25 stops the operation of the ventilation system. Specifically, the controller 25 controls the slat drive unit 40 of the shutter device 30 to close the upper region 32a and the lower region 32c of the shutter curtain 32, that is, to close the entire region of the shutter curtain 32. The controller 25 stops the supply fan 14 and the exhaust fan 16.

  On the other hand, if it is determined in step S12 that there is an abnormality in the ventilator, the controller 25 performs warning display (screen display, audio display, etc.) in step S19, and then ends the execution of the current program.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In response to the engine start request signal from the remote control 26, the ventilation system of the garage 11 is activated. By operating the ventilator in association with the engine start in this way, ventilation can be started before the exhaust gas concentration in the garage 11 increases. In addition, the user of the building 10 only needs to operate the remote controller 26 that requests the engine start of the vehicle 50, and does not need to operate the remote controller 26 and the building controller 25 in consideration of ventilation in the garage 11. . That is, the environment in the garage 11 can be kept good without making the vehicle user aware of ventilation.

  In addition, a ventilation flow that flows from the supply port to the exhaust port was generated in the garage 11 by the ventilation system. Thereby, the exhaust gas of the vehicle 50 can be efficiently exhausted outdoors by being put on the ventilation flow.

  Further, the ventilation flow is made to flow in the vicinity of the muffler 51 of the vehicle 50. Thereby, before the exhaust gas of the vehicle 50 diffuses into the garage 11, the exhaust gas of the vehicle 50 can be put on the ventilation flow and discharged outside. Moreover, the adhesion of the soot contained in the exhaust gas of the vehicle 50 to the inner wall surface of the garage 11 can be suppressed.

  In particular, when the muffler 51 of the vehicle 50 is parked so as to face the back side of the garage 11, the exhaust gas is guided downward along the ventilation flow, so that the exhaust gas may diffuse into the garage 11. There is no exhaust gas ventilation efficiency. On the other hand, when the muffler 51 of the vehicle 50 is parked so as to face the entrance / exit 17 side of the garage 11, the exhaust gas is immediately exhausted from the lower region 32c of the shutter curtain 32 along the ventilation flow. Increases gas ventilation efficiency. Therefore, even if the vehicle 50 is stopped in the front or rear direction in the garage 11, the exhaust gas can be efficiently discharged outdoors.

  The engine of the vehicle 50 is started after the ventilation flow is generated in the garage 11. Thereby, the exhaust gas of the vehicle 50 can be efficiently discharged to the outdoors from the beginning of the engine start.

  Moreover, the ventilation system of the garage 11 was stopped on the condition that the exhaust gas concentration in the garage 11 became a predetermined value or less. Thus, by operating the ventilation system until the exhaust gas concentration in the garage 11 becomes a predetermined value or less, the environment in the garage 11 can be maintained at a certain level or more.

  Further, the ventilation system of the garage 11 is stopped on the condition that the exhaust gas concentration in the garage 11 becomes equal to or lower than the predetermined value and that the vehicle 50 is delivered or the engine of the vehicle 50 is stopped. did. In this way, by operating the ventilation system until the cause of the deterioration of the exhaust gas concentration in the garage 11 is eliminated, the environment in the garage 11 can be reliably maintained at a certain level or higher.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, the engine of the vehicle 50 is started after a predetermined time (for example, 5 seconds) has elapsed since the start of ventilation in the garage 11. However, the present invention is not limited to this, and the engine may be started immediately after the start of ventilation or simultaneously with the start of ventilation. Further, ventilation in the garage 11 may be started immediately after the engine is started or after a predetermined time has elapsed since the start of the engine. However, considering that high-concentration exhaust gas is generated immediately after the engine is started, it is optimal to first start the engine after generating a ventilation flow in the garage 11 as in the above embodiment.

  In the above embodiment, the building controller 25 centrally manages the operation start timing and engine start timing of the ventilation device. However, the present invention is not limited to this, and the ECU 52 of the vehicle 50 may notify the building controller 25 of the engine start, and the building controller 25 may receive this notification and start ventilation in the garage 11.

  In the above embodiment, ventilation in the garage 11 is terminated on the condition that the exhaust gas concentration in the garage 11 has become equal to or less than a predetermined value, and that the vehicle 50 has left the vehicle or the vehicle engine has stopped. However, the present invention is not limited to this, and ventilation in the garage 11 may be terminated only on the condition that the exhaust gas concentration in the garage 11 has become a predetermined value or less.

  In the above embodiment, the exhaust gas concentration in the garage 11 is set as the ventilator stop condition. However, when an abnormality occurs in the ventilator, there is a concern about deterioration of the environment in the garage 11. Therefore, the exhaust gas concentration in the garage 11 may be used as the engine stop condition of the vehicle 50. That is, when the exhaust gas concentration in the garage 11 becomes abnormal at a predetermined value, the building controller 25 may forcibly stop the engine of the vehicle 50. Specifically, an engine stop signal is transmitted from the building controller 25 to the ECU 52 of the vehicle 50 when the detected value of the exhaust gas concentration sensor 23 becomes a predetermined value or more.

  In the above embodiment, the air supply duct 13 is provided between the ceiling material 18 of the garage 11 and the floor material 19 of the living room 12.
