In the dust collection device according to the background art, dust that is not caught in the dust collection air current and cannot be collected by the dust collection means remains in the room even after cleaning, so the dust removal effect is insufficient.

The present invention was made in consideration of these circumstances, and aims to provide a dust removal control system and a dust removal control method that can effectively remove dust remaining after cleaning, thereby improving the dust removal effect.

The dust removal control system according to the first aspect of the present invention is a dust removal control system for removing dust from within a room of a building, and includes a control device and a self-propelled cleaning robot that can be remotely controlled by the control device. The control device starts the operation of the cleaning robot in the room when no occupants of the building are present, and after the operation of the cleaning robot is terminated, performs airflow control to set the airflow state in the room to a second state with higher ventilation efficiency than a reference first state, and performs exhaust control to exhaust the air in the room to the outside of the building.

According to the first aspect, after the operation of the cleaning robot is completed, the control device performs airflow control to set the airflow state in the living room to a second state with higher ventilation efficiency than the reference first state, and performs exhaust control to exhaust the air in the living room to the outside of the building. This makes it possible to effectively exhaust dust remaining in the living room after cleaning by the cleaning robot to the outside of the building, thereby improving the dust removal effect.

The dust removal control system according to the second aspect of the present invention, in the first aspect, further comprises a dust sensor that detects dust floating in the room and transmits a detection result including particle size information indicating the particle size of the detected dust to the control device, and the control device further performs airflow control to set the airflow state in the room to a third state that is weaker than the first state when the dust sensor detects dust with a particle size equal to or greater than a threshold value after the operation of the cleaning robot has ended, and after waiting for a predetermined time, restarts the operation of the cleaning robot in the room.

According to the second aspect, when the dust sensor detects dust particles having a particle size equal to or larger than a threshold value after the operation of the cleaning robot has ended, the control device performs airflow control to set the airflow state in the room to a third state that is weaker than the first state, and restarts the operation of the cleaning robot in the room after waiting for a predetermined time. In this way, by restarting the operation of the cleaning robot after waiting for dust particles having a particle size equal to or larger than a threshold value to fall, the large dust particles remaining in the room after the first cleaning by the cleaning robot can be effectively removed in the next cleaning by the cleaning robot, and as a result, the dust removal effect can be further improved.

The dust removal control system according to the third aspect of the present invention, in the second aspect, further comprises an occupant room air intake grill installed in the occupant room and remotely operable by the control device, and a non-occupant room air intake grill installed in a non-occupant room connected to the occupant room and remotely operable by the control device independently of the occupant room air intake grill, and the control device stops both the occupant room air intake grill and the non-occupant room air intake grill in the airflow control in the third state.

According to the third aspect, in the airflow control in the third state, the control device stops both the living room air supply grille and the non-living room air supply grille. This makes it possible to weaken the airflow in the living room, thereby facilitating the fall of dust suspended in the living room.

The dust removal control system according to the fourth aspect of the present invention, in any one of the first to third aspects, further includes a dust sensor that detects dust floating in the room and transmits a detection result including particle size information indicating the particle size of the detected dust to the control device, and when the dust sensor detects dust with a particle size less than a threshold value after the operation of the cleaning robot has ended, the control device performs the airflow control to set the airflow state in the room to the second state and also performs the exhaust control.

According to the fourth aspect, when the dust sensor detects small dust particles below a threshold value after the cleaning robot has finished operating, the control device performs airflow control to set the airflow state in the room to the second state and also performs exhaust control. This allows small dust particles floating in the room after cleaning by the cleaning robot to be effectively exhausted to the outside of the building by the airflow control and exhaust control in the second state, thereby improving the dust removal effect.

The dust removal control system according to the fifth aspect of the present invention, in the fourth aspect, further comprises an occupant room air intake grill installed in the occupant room and remotely operable by the control device, and a non-occupant room air intake grill installed in a non-occupant room connected to the occupant room and remotely operable by the control device independently of the occupant room air intake grill, and the control device drives both the occupant room air intake grill and the non-occupant room air intake grill in the airflow control in the second state.

According to the fifth aspect, in the second state of airflow control, the control device drives both the living room air supply grille and the non-occupied room air supply grille. This generates an airflow with high ventilation efficiency from the non-occupied room to the living room, which can promote the discharge of dust suspended in the living room.

The dust removal control system according to the sixth aspect of the present invention, in any one of the first to fifth aspects, further includes a dust sensor that detects dust floating in the living room and transmits a detection result including particle size information indicating the particle size of the detected dust to the control device, and the control device further performs airflow control to set the airflow state in the living room to the first state if the dust sensor does not detect dust after the operation of the cleaning robot has ended.

According to the sixth aspect, when the dust sensor does not detect dust after the operation of the cleaning robot is finished, the control device performs airflow control to set the airflow state in the living room to the first state. This makes it possible to avoid unnecessary airflow control and exhaust control in the second state being performed when the dust sensor does not detect dust.

The dust removal control system according to the seventh aspect of the present invention, in the sixth aspect, further comprises an occupant air intake grill installed in the occupant room and remotely operable by the control device, a non-occupant air intake grill installed in a non-occupant room connected to the occupant room and remotely operable by the control device independently of the occupant air intake grill, and a non-occupant room ventilator installed in the non-occupant room and remotely operable by the control device, and the control device drives the occupant air intake grill and the non-occupant room ventilator and stops the non-occupant air intake grill in the airflow control in the first state.

According to the seventh aspect, in the first state of airflow control, the control device drives the living room air supply grille and the non-occupied room ventilator fan, and stops the non-occupied room air supply grille. This creates an airflow from the living room to the non-occupied room, preventing dust from the non-occupied room from entering the living room.

According to the eighth aspect, when the direction of the outside air is such that an airflow is generated from a non-occupied room to an occupied room, and the pollution state of the outside air is below a threshold, the control device opens both the automatic opening and closing windows for the occupied room and the automatic opening and closing windows for the non-occupied room in the exhaust control. This allows dust remaining in the occupied room after cleaning by the cleaning robot to be effectively exhausted to the outside of the building by the airflow from the non-occupied room to the occupied room, thereby further improving the dust removal effect. In addition, because the airflow is generated by the outside air, the ventilation efficiency and the number of ventilations can be improved and power consumption can be reduced compared to when the airflow is generated by a blower such as an air conditioner or air purifier.

According to the ninth aspect, when the direction of the outside air is not a direction that generates an airflow from a non-occupied room to an occupied room and the pollution state of the outside air is below a threshold, the control device opens the automatic opening and closing window for the occupied room and closes the automatic opening and closing window for the non-occupied room in the exhaust control. This allows dust remaining in the occupied room after cleaning by the cleaning robot to be effectively exhausted to the outside of the building by ventilation caused by opening the automatic opening and closing window for the occupied room, thereby making it possible to further improve the dust removal effect. In addition, because the airflow is generated by the wind from the outside air, it is possible to improve the ventilation efficiency and the number of ventilation changes and reduce power consumption compared to when the airflow is generated by a blower such as an air conditioner or air purifier.

According to the eleventh aspect, the control device sets the airflow rate of the blower device in the second state to be greater than the airflow rate of the blower device in the first state. This allows the airflow rate of the blower device to be further strengthened, thereby further improving the dust removal effect.

The dust removal control system according to the twelfth aspect of the present invention is any one of the first to eleventh aspects, further comprising a dust sensor that detects dust floating in the living room and transmits the detection result to the control device, and when the dust sensor detects dust at or above a threshold value while the resident is absent, the control device performs airflow control to set the airflow state in the living room to a third state that is weaker than the first state, and after waiting for a predetermined time, starts operating the cleaning robot in the living room.

According to the twelfth aspect, before starting to drive the cleaning robot, the control device performs airflow control to set the airflow state in the living room to a third state that is weaker than the first state, and waits for a predetermined time. In this way, by waiting for dust suspended in the living room to fall before starting to drive the cleaning robot, dust in the living room can be effectively removed by cleaning with the cleaning robot, and as a result, the dust removal effect can be further improved.

The dust removal control method according to the thirteenth aspect of the present invention is a dust removal control method for removing dust from within a room of a building, in which a control device starts driving a self-propelled cleaning robot in the room when no occupants of the building are present, and after driving of the cleaning robot ends, performs airflow control to set the airflow state in the room to a second state having higher ventilation efficiency than a reference first state, and performs exhaust control to exhaust the air in the room to the outside of the building.

In control pattern PH2, the living room air intake grille 14 is set to "on", the non-occupied room air intake grille 15 is set to "on", the living room exhaust fan 16 is set to "off", the non-occupied room exhaust fan 17 is set to "off", the living room automatic opening and closing window 18 is set to "open", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "on", the air purifier 21 is set to "high", and the auxiliary exhaust fan 22 is set to "off".

In control pattern PH3, the living room air intake grille 14 is set to "on", the non-occupied room air intake grille 15 is set to "on", the living room exhaust fan 16 is set to "on", the non-occupied room exhaust fan 17 is set to "off", the living room automatic opening and closing window 18 is set to "closed", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "on", the air purifier 21 is set to "high", and the auxiliary exhaust fan 22 is set to "on".

Figure 4 is a diagram showing an example of wind direction data 52. Wind direction data 52 is data that specifies the wind direction of outside air that may generate an airflow from non-occupied room R2 to occupied room R1 in building 100 when both occupant room automatic opening and closing window 18 and non-occupant room automatic opening and closing window 19 are opened. Wind direction data 52 is created in advance by an operator at the time of system installation by referring to location information including the direction of building 100 and floor plan information, etc., and is stored in memory unit 32. However, if the floor plan of building 100 has changed since the system was installed due to an extension, renovation, etc., the operator or resident themselves can update wind direction data 52 by referring to the changed floor plan information, etc.

In this embodiment, the occupant room automatic opening and closing window 18 is a south-facing window, and the non-occupant room automatic opening and closing window 19 is a north-facing window. Therefore, in the wind direction data 52, as the wind direction of the outside air that may generate a south-facing airflow from the non-occupant room R2 to the occupant room R1, "○" is set for the north, northeast, and northwest directions, and "×" is set for the other directions. In other words, when the outside air direction is north, northeast, or northwest, by opening both the occupant room automatic opening and closing window 18 and the non-occupant room automatic opening and closing window 19, the occupant room automatic opening and closing window 18 will be upwind and the non-occupant room automatic opening and closing window 19 will be downwind, generating a south-facing airflow from the non-occupant room R2 to the occupant room R1 within the building 100.

Figures 5 and 6 are flowcharts showing the flow of processing executed by the processing unit 31 of the control device 11.

First, in step S11, the processing unit 31 determines whether or not there is a person at home in the building 100. The processing unit 31 acquires the detection result data of the lock sensor 23 and the human presence sensors 24, 25 via the communication unit 35. Based on the acquired detection result data, the processing unit 31 determines that there is no person at home in the building 100 if the front door is locked and the human presence sensors 24, 25 have not detected a person for a predetermined period of time (e.g., 30 minutes) or more.

If there is a person at home in the building 100 (step S11: NO), the processing unit 31 repeatedly executes step S11.

If the time when no one is present in the building 100 continues for a predetermined time or more (step S11: YES), the processing unit 31 next sets the control pattern PM in step S12. The predetermined time is, for example, several minutes to several tens of minutes. In the control pattern PM, the living room air supply grill 14 is set to "on", the non-occupied room air supply grill 15 is set to "off", the living room ventilator 16 is set to "off", the non-occupied room ventilator 17 is set to "on", the living room automatic opening and closing window 18 is set to "closed", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "off", the air purifier 21 is set to "strong", and the auxiliary ventilator 22 is set to "off". This generates an airflow from the living room R1 toward the non-occupied room R2, preventing dust in the non-occupied room R2 from entering the living room R1.

Next, in step S13, the processing unit 31 determines whether or not to perform cleaning of the living room R1 by the cleaning robot 12. For example, cleaning conditions are set in advance based on the day of the week and the time and stored in the memory unit 32, and the processing unit 31 determines whether or not the current day of the week and the current time satisfy the cleaning conditions.

If cleaning is not performed (step S13: NO), the processing unit 31 ends the process.

If cleaning is to be performed (step S13: YES), the processing unit 31 then sets the control pattern PL in step S14. In the control pattern PL, the living room air supply grille 14 is set to "off", the non-occupied room air supply grille 15 is set to "off", the living room exhaust fan 16 is set to "off", the non-occupied room exhaust fan 17 is set to "on", the living room automatic opening and closing window 18 is set to "closed", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "off", the air purifier 21 is set to "low", and the auxiliary exhaust fan 22 is set to "on".

Next, in step S15, the processing unit 31 determines whether the amount of dust in the living room R1 is equal to or greater than a predetermined threshold value Th1. The processing unit 31 acquires the detection result data of the dust sensor 13 via the communication unit 35. The processing unit 31 determines whether the amount of dust floating in the living room R1 is equal to or greater than the threshold value Th1 based on the dust amount information contained in the acquired detection result data.

If the amount of dust in room R1 is equal to or greater than threshold value Th1 (step S15: YES), then in step S16, the processing unit 31 waits for a predetermined time. This predetermined time is, for example, the time until the amount of dust in room R1 falls below threshold value Th1, and may be set to a maximum value (e.g., 30 minutes). By waiting for a predetermined time with the control pattern PL set to a weak airflow, dust floating in room R1 can be allowed to fall to the floor.

If the amount of dust in room R1 is less than threshold value Th1 (step S15: NO), then in step S17, processing unit 31 sends a cleaning start signal to cleaning robot 12 via communication unit 35. This causes cleaning robot 12 to start driving the cleaning operation, and while autonomously traveling within room R1, it collects dust and debris that has accumulated on the floor of room R1. After driving the cleaning operation is completed, cleaning robot 12 sends a cleaning completion signal to control device 11.

Next, in step S18, the processing unit 31 determines whether or not a cleaning completion signal has been received from the cleaning robot 12.

If a cleaning completion signal has not been received from the cleaning robot 12 (step S18: NO), then in step S19, the processing unit 31 waits until a cleaning completion signal is received.

If a cleaning completion signal is received from the cleaning robot 12 (step S18: YES), then in step S20, the processing unit 31 determines whether the amount of large-diameter dust particles in the living room R1 is equal to or greater than a predetermined threshold value Th2. The processing unit 31 acquires the detection result data of the dust sensor 13 via the communication unit 35. Based on the dust amount information and particle size information contained in the acquired detection result data, the processing unit 31 determines whether the amount of large-diameter dust particles (e.g., 10 μm or larger) floating in the living room R1 is equal to or greater than the threshold value Th2.

If the amount of large-sized dust particles in room R1 is equal to or greater than threshold value Th2 (step S20: YES), then in step S21, the processing unit 31 waits for a predetermined time (e.g., 5 minutes) required for the large-sized dust particles to fall to the floor, and then repeats the processing from step S17 onward. In other words, the processing unit 31 starts driving the cleaning robot 12 again in room R1.

If the amount of large-diameter dust in room R1 is less than threshold value Th2 (step S20: NO), then in step S22, the processing unit 31 determines whether the amount of small-diameter dust in room R1 is equal to or greater than a predetermined threshold value Th3. The processing unit 31 acquires detection result data from the dust sensor 13 via the communication unit 35. Based on the dust amount information and particle size information contained in the acquired detection result data, the processing unit 31 determines whether the amount of small-diameter dust (e.g., less than 10 μm) floating in room R1 is equal to or greater than threshold value Th3.

If the amount of small-diameter dust particles in room R1 is equal to or greater than threshold value Th3 (step S22: YES), then in step S23, processing unit 31 executes the airflow exhaust control shown in FIG. 6.

If the amount of small-diameter dust particles in room R1 is less than threshold value Th3 (step S22: NO), then in step S24, the processing unit 31 records cleaning data such as the date cleaning was performed in the memory unit 32, and then ends the process.

6, first, in step S31, the processing unit 31 determines whether or not the pollution level of the outside air of the building 100 is equal to or higher than a predetermined threshold value Th4. The processing unit 31 acquires detection result data of the outside air sensor 26 via the communication unit 35. The processing unit 31 determines whether or not the pollution level of the outside air is equal to or higher than the threshold value Th4 based on the pollution level information included in the acquired detection result data. The threshold value Th4 is set to 35 μg/ ^m3 for PM2.5, for example.

If the pollution level of the outside air is less than the threshold value Th4 (step S31: NO), then in step S32, the processing unit 31 determines whether the wind speed of the outside air is equal to or greater than a predetermined threshold value Th5. The processing unit 31 acquires the detection result data of the outside air sensor 26 via the communication unit 35. The processing unit 31 determines whether the wind speed of the outside air is equal to or greater than the threshold value Th5 based on the wind speed information included in the acquired detection result data. The threshold value Th5 is set to, for example, 10 m/s.

If the wind speed of the outside air is less than the threshold value Th5 (step S32: NO), then in step S33, the processing unit 31 determines whether the wind direction of the outside air is a predetermined wind direction. The processing unit 31 acquires the detection result data of the outside air sensor 26 via the communication unit 35. The processing unit 31 compares the wind direction information included in the acquired detection result data with the wind direction data 52 read from the memory unit 32 to determine whether the wind direction of the outside air is a wind direction that can generate an airflow from the non-occupied room R2 to the occupied room R1 within the building 100.

If the direction of the outside air is the specified direction (step S33: YES), the processing unit 31 then sets the control pattern PH1 in step S34. In control pattern PH1, the living room air supply grille 14 is set to "on", the non-occupied room air supply grille 15 is set to "on", the living room ventilation fan 16 is set to "off", the non-occupied room ventilation fan 17 is set to "off", the living room automatic opening and closing window 18 is set to "open", the non-occupied room automatic opening and closing window 19 is set to "open", the air conditioner 20 is set to "on", the air purifier 21 is set to "strong", and the auxiliary ventilation fan 22 is set to "off". This allows the outside air taken in through the non-occupied room automatic opening and closing window 19 to generate an airflow with high ventilation efficiency from the non-occupied room R2 toward the living room R1. In addition, dust remaining in the living room R1 after cleaning by the cleaning robot 12 can be exhausted to the outside of the building 100 through the automatic opening and closing window 18 in the living room by the highly efficient airflow from the non-living room R2 toward the living room R1.

If the direction of the outside air is not the specified direction (step S33: NO), the processing unit 31 next sets the control pattern PH2 in step S35. In the control pattern PH2, the living room air supply grille 14 is set to "on", the non-occupied room air supply grille 15 is set to "on", the living room exhaust fan 16 is set to "off", the non-occupied room exhaust fan 17 is set to "off", the living room automatic opening and closing window 18 is set to "open", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "on", the air purifier 21 is set to "strong", and the auxiliary exhaust fan 22 is set to "off". As a result, dust remaining in the living room R1 after cleaning by the cleaning robot 12 can be exhausted to the outside of the building 100 from the living room automatic opening and closing window 18 by the airflow with high ventilation efficiency caused by opening the living room automatic opening and closing window 18.

If the pollution level of the outside air is equal to or higher than the threshold value Th4 (step S31: YES), or if the wind speed of the outside air is equal to or higher than the threshold value Th5 (step S32: YES), the processing unit 31 next sets the control pattern PH3 in step S36. In the control pattern PH3, the living room air supply grille 14 is set to "on", the non-occupied room air supply grille 15 is set to "on", the living room ventilation fan 16 is set to "on", the non-occupied room ventilation fan 17 is set to "off", the living room automatic opening and closing window 18 is set to "closed", the non-occupied room automatic opening and closing window 19 is set to "closed", the air conditioner 20 is set to "on", the air purifier 21 is set to "strong", and the auxiliary ventilation fan 22 is set to "on". This allows an airflow with high ventilation efficiency to be generated from the non-occupied room R2 toward the living room R1, and dust remaining in the living room R1 after cleaning by the cleaning robot 12 can be exhausted to the outside of the building 100 from the living room ventilation fan 16.

After steps S34 to S36, in step S37, the processing unit 31 waits for a predetermined time. This predetermined time is the time required for dust remaining in the living room R1 after cleaning by the cleaning robot 12 to be exhausted to the outside of the building 100. The predetermined time may be, for example, the time until the amount of small-diameter dust in the living room R1 falls below the threshold value Th3, or a maximum value (e.g., 30 minutes) may be set.

Note that if the pollution level of the outside air becomes equal to or exceeds the threshold value Th4 during standby with control pattern PH1 set, or if the wind speed of the outside air becomes equal to or exceeds the threshold value Th5, the processing unit 31 may thereafter change control pattern PH1 to control pattern PH3.

In addition, if the direction of the outside air is no longer the specified direction while the control pattern PH1 is set and the processing unit 31 waits, the control pattern PH1 may be changed to control pattern PH2 thereafter.

After the standby process of step S37, the processing unit 31 executes the cleaning data recording process of step S24 shown in FIG. 5.

If the lock sensor 23 or the human presence sensors 24 and 25 detect that the resident has returned home while the processing shown in Figures 5 and 6 is being performed, the processing unit 31 may display a message on the display unit 34 to allow the resident to select whether to continue or stop the processing.

In addition, if a communication error or the like occurs in the control device 11 or any of the devices while the processing shown in Figures 5 and 6 is being executed, the processing unit 31 may forcibly set the control pattern PM after detecting the error and may display an error message on the display unit 34.

According to the dust removal control system of this embodiment, after the operation of the cleaning robot 12 has ended, the control device 11 performs airflow control to set the airflow state in the living room R1 to one of the control patterns PH1 to PH3 that has higher ventilation efficiency than the standard control pattern PM, and also performs exhaust control to exhaust the air in the living room R1 to the outside of the building 100. This allows dust remaining in the living room R1 after cleaning by the cleaning robot 12 to be effectively exhausted to the outside of the building 100, thereby improving the dust removal effect.

Furthermore, if the dust sensor 13 detects large dust particles after the drive of the cleaning robot 12 has ended, the control device 11 performs airflow control to set the airflow state in the living room R1 to control pattern PL, which is weaker than control pattern PM, and restarts the drive of the cleaning robot 12 in the living room R1 after waiting for a predetermined time. In this way, by restarting the drive of the cleaning robot 12 after waiting for large dust particles equal to or larger than the threshold value Th2 to fall, the large dust particles remaining in the living room R1 after the first cleaning by the cleaning robot 12 can be effectively removed in the next cleaning by the cleaning robot 12, and as a result, the dust removal effect can be further improved.

In addition, in the airflow control of control pattern PL, the control device 11 stops both the living room air supply grille 14 and the non-living room air supply grille 15. This weakens the airflow in the living room R1, which can promote the fall of dust suspended in the living room R1.

In addition, when the dust sensor 13 detects small dust particles after the cleaning robot 12 has finished operating, the control device 11 performs airflow control to set the airflow state in the living room R1 to one of the control patterns PH1 to PH3, and also performs exhaust control. This allows small dust particles floating in the living room R1 after cleaning by the cleaning robot 12 to be effectively exhausted to the outside of the building 100 by the airflow control and exhaust control of the control patterns PH1 to PH3, thereby improving the dust removal effect.

In addition, in the airflow control of control patterns PH1 to PH3, the control device 11 drives both the occupant room air supply grille 14 and the non-occupant room air supply grille 15. This creates an airflow with high ventilation efficiency from the non-occupant room R2 toward the occupant room R1, which can promote the discharge of dust suspended in the occupant room R1.

In addition, if the dust sensor 13 does not detect dust after the operation of the cleaning robot 12 has ended, the control device 11 performs airflow control to set the airflow state in the living room R1 to control pattern PM. This makes it possible to avoid unnecessary airflow control and exhaust control of control patterns PH1 to PH3 being executed when the dust sensor 13 does not detect dust.

In addition, in the airflow control of control pattern PM, the control device 11 drives the occupant room air supply grille 14 and the non-occupant room ventilation fan 17, and stops the non-occupant room air supply grille 15. This creates an airflow from the occupant room R1 toward the non-occupant room R2, preventing dust in the non-occupant room R2 from entering the occupant room R1.

In addition, when the direction of the outside air is such that an airflow is generated from the non-occupied room R2 toward the occupied room R1 and the pollution state of the outside air is less than the threshold value Th4, the control device 11 opens both the occupied room automatic opening and closing window 18 and the non-occupied room automatic opening and closing window 19 in the exhaust control. This allows dust remaining in the occupied room R1 after cleaning by the cleaning robot 12 to be effectively exhausted to the outside of the building 100 by the airflow from the non-occupied room R2 toward the occupied room R1, thereby further improving the dust removal effect. In addition, because the airflow is generated by the outside air, the ventilation efficiency and the number of ventilations can be improved and power consumption can be reduced compared to when the airflow is generated by a blower such as the air conditioner 20 or the air purifier 21.

Furthermore, when the direction of the outside air is not in a direction that generates an airflow from the non-occupied room R2 to the occupied room R1 and the pollution state of the outside air is less than the threshold value Th4, the control device 11 opens the occupant room automatic opening and closing window 18 and closes the non-occupied room automatic opening and closing window 19 in the exhaust control. This allows dust remaining in the occupant room R1 after cleaning by the cleaning robot 12 to be effectively exhausted to the outside of the building 100 by ventilation caused by opening the occupant room automatic opening and closing window 18, thereby making it possible to further improve the dust removal effect. In addition, because the airflow is generated by the wind from the outside air, the ventilation efficiency and the number of ventilation changes can be improved and power consumption can be reduced compared to when the airflow is generated by a blower such as the air conditioner 20 or air purifier 21.

In addition, when the polluted state of the outside air is equal to or higher than the threshold value Th4, the control device 11 closes both the automatic opening and closing window 18 in the living room and the automatic opening and closing window 19 in the non-living room during exhaust control, and drives the living room ventilation fan 16. This makes it possible to prevent polluted outside air from being taken into the building 100.

The control device 11 also sets the airflow rate of the air blower, such as the air conditioner 20, in the control patterns PH1 to PH3 to be greater than the airflow rate of the air blower in the control pattern PM. This allows the airflow to be further strengthened by the air blower, thereby further improving the dust removal effect.

In addition, before starting to drive the cleaning robot 12, the control device 11 performs airflow control to set the airflow state in the living room R1 to control pattern PL, which is weaker than control pattern PM, and waits for a predetermined time. In this way, by waiting for the dust suspended in the living room R1 to fall before starting to drive the cleaning robot 12, the dust in the living room R1 can be effectively removed by the cleaning robot 12, and as a result, the dust removal effect can be further improved.
