DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The embodiments for implementing the air blowing system and the air conditioning system according to the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. In the following description, for convenience, the positional relationship of each structure may be expressed based on the illustrated state. Note that the present disclosure is not limited to the following embodiments, and it is possible to freely combine each embodiment, modify any component of each embodiment, or omit any component of each embodiment within the scope of the present disclosure.

[0011] Embodiment 1 A first embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 5. Fig. 1 is a plan view showing a schematic example of a building to which a ventilation system is applied. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. Fig. 3 is a block diagram showing a configuration of a control system for the ventilation system. Fig. 4 is a diagram showing an air flow when a ventilation device in the ventilation system is operating. Fig. 5 is a flow diagram showing an example of the operation of the ventilation system.

[0012] FIG. 1 is a schematic diagram showing an example of a building 10 in which a ventilation system according to this embodiment is installed. As shown in the figure, the building 10 has one or more rooms. In the example shown in the figure, a first space 11 and a second space 12 are formed as the internal space of the room. The first space 11 is, for example, the internal space of a living room. As defined in, for example, Article 2, Paragraph 4 of the Building Standards Act, a living room is a room that is continuously used for residence, office work, work, meetings, entertainment, or other similar purposes. Specific examples of living rooms include a living room, a dining room, a kitchen, a Japanese-style room, and a bedroom.

[0013] The second space 12 is, for example, the internal space of a non-habitable room. A non-habitable room is a room other than an occupant room provided in the building 10. Specific examples of non-habitable rooms include a toilet (restroom), a bathroom, a dressing room, a washroom, a laundry room, a walk-in closet, and the like. In particular, the second space 12 here is the internal space of a room suitable for drying washed clothes indoors, such as a bathroom, a dressing room, a washroom, or a laundry room. In the example shown in FIG. 1, a third space 13 is formed in the building 10. Here, the third space 13 is the internal space of a corridor and an entrance hall.

[0014] A first door 14 is provided between the first space 11 and the third space 13. A second door 15 is provided between the second space 12 and the third space 13. A front door 16 leading to the outside is provided in the third space 13.

[0015] As shown in Figs. 1 and 2, a duct 20 is provided above the ceiling of the first space 11 and the second space 12. One end of the duct 20 is connected to an intake port 21 formed in the ceiling of the first space 11. The other end of the duct 20 is connected to an exhaust port 22 formed in the ceiling of the second space 12. An air passage that connects the first space 11 and the second space 12 is formed inside the duct 20. A blower 30 is provided in the middle of the duct 20. The blower 30 has a built-in fan.

[0016] When the blower 30 operates, that is, when the fan of the blower 30 operates, an airflow is generated in the air passage in the duct 20, moving from the first space 11 side to the second space 12 side. When the blower 30 operates, air in the first space 11 is sucked into the duct 20 through the intake port 21. The air sucked into the duct 20 moves toward the second space 12 side, and is blown out from the exhaust port 22 into the second space 12. In this way, the blower 30 transports the air in the first space 11 to the second space 12.

[0017] The air passage connecting the first space 11 and the second space 12 is not limited to the duct 20 installed above the ceiling. For example, if the first space 11 and the second space 12 are adjacent rooms, an air passage connecting the first space 11 and the second space 12 may be formed by a duct or the like provided through a wall separating the first space 11 and the second space 12.

[0018] In addition, the arrangement of the first space 11, the second space 12, and the third space 13 is not limited to the example in Figures 1 and 2. However, even when the first door 14 and the second door 15 are closed, the first space 11 and the second space 12 allow air to flow through a place other than the air passage in the duct 20 described above, for example, through a gap such as an undercut of each door, or a vent provided in each door or wall.

[0019] The air blowing system according to this embodiment includes a control device 100 as shown in Fig. 1. The control device 100 controls the operation of the air blowing device 30. As shown in Fig. 3, the control device 100 includes an information acquisition unit 111 and a control unit 112. The information acquisition unit 111 acquires various information necessary for the operation of the air blowing device 30. The control unit 112 controls the operation of the air blowing device 30 based on the information acquired by the information acquisition unit 111. As shown in the figure, the air blowing system includes an environmental sensor 60. The environmental sensor 60 is a sensor that detects physical quantities related to one or both of the internal and external environments of the building 10.

[0020] Specific examples of physical quantities related to the external environment of the building 10 include the temperature and humidity (one or both of relative humidity and absolute humidity) of the air (outside air) outside the building 10. Specific examples of physical quantities related to the internal environment of the building 10 include the following:

[0021] The temperature and humidity (one or both of relative humidity and absolute humidity) of the air in the first space 11 The temperature and humidity (one or both of relative humidity and absolute humidity) of the air in the second space 12 The temperature and humidity (relative humidity and / or absolute humidity) of the air in the third space 13

[0022] The environmental sensor 60 has a sensor corresponding to a physical quantity to be detected. The sensor is basically installed at a location to be detected.

[0023] Information acquisition unit 111 periodically (e.g., every few minutes) acquires the detection result of environmental sensor 60. Environmental sensor 60 and information acquisition unit 111 constitute environmental information acquisition means for acquiring environmental information. Then, control unit 112 controls the operation of blower device 30 according to the detection result of environmental sensor 60 acquired by information acquisition unit 111, i.e., according to the environmental information acquired by the environmental information acquisition means.

[0024] FIG. 4 shows the main air flow when the blower 30 is in operation. The air flow when the blower 30 is in operation is indicated by dashed lines and arrows. By the operation of the blower 30, the air in the first space 11 flows into the duct 20 through the inlet 21 and is transported to the second space 12 through the outlet 22. When laundry clothes are hung out to dry in the second space 12, it is considered that the humidity in the second space 12 increases locally. In response to this, by transporting the air in the first space 11, where the humidity is normal, the humidity in the second space 12 can be reduced, and the drying of the clothes in the second space 12 can be promoted. In addition to transporting low-humidity air, by generating an airflow in the second space 12, the air around the clothes can be circulated, and it is possible to promote the release of moisture from the clothes.

[0025] The control unit 112 of the control device 100 starts the operation of the air blower 30 when a preset start condition is satisfied while the air blower 30 is stopped. That is, when the start condition is satisfied while the air blower 30 is stopped, the air blower 30 starts transporting air from the first space 11 to the second space 12.

[0026] Next, an example of a start condition for the operation of the blower 30 will be described. A first example of the start condition for the operation of the blower 30 is that the humidity in the second space 12 has increased by a preset first reference humidity or more within a preset first reference time. In this case, the environment sensor 60 can detect at least the humidity of the air in the second space 12. That is, the environment information acquisition means acquires information on the humidity in the second space 12. Then, the control unit 112 of the control device 100 starts the operation of the blower 30 when the humidity in the second space 12 has increased by the first reference humidity or more within the first reference time. The first reference time is, for example, 10 minutes. The first reference humidity is, for example, 5% relative humidity. In this case, the environment sensor 60 detects at least the relative humidity of the air in the second space 12.

[0027] A second example of the start condition for the operation of the blower 30 is that, in addition to the first example described above, the humidity of the outside air is equal to or lower than a second reference humidity set in advance. In this case, the environment sensor 60 can further detect the humidity of the outside air. That is, the environment information acquisition means acquires information on the humidity of the outside air. Then, the control unit 112 of the control device 100 starts the operation of the blower 30 when the humidity of the second space 12 increases to equal to or higher than the first reference humidity within the first reference time and the humidity of the outside air is equal to or lower than the second reference humidity. Specific examples of the first reference time and the first reference humidity are the same as those of the first example described above. The second reference humidity is, for example, 80% relative humidity. In this case, the environment sensor 60 detects the relative humidity of the air in the second space 12 and the relative humidity of the outside air.

[0028] The control device 100 stops the operation of the blower device 30 when a preset stop condition is satisfied during the operation of the blower device 30. That is, the blower device 30 stops the transport of air from the first space 11 to the second space 12 when the stop condition is satisfied during the operation of the blower device 30. An example of a stop condition for the operation of the blower device 30 is that the humidity of the outside air has increased by a preset third reference humidity or more within a preset second reference time. In this case, the environmental sensor 60 is capable of detecting the humidity of the outside air. That is, the environmental information acquisition means acquires information regarding the humidity of the outside air. Then, the control unit 112 of the control device 100 stops the operation of the blower device 30 when the humidity of the outside air has increased by the third reference humidity or more within the second reference time. The second reference time is, for example, 10 minutes. The third reference humidity is, for example, 5% in relative humidity. In this case, the environmental sensor 60 detects at least the relative humidity of the outside air.

[0029] For example, when the humidity of the outside air is high, the humidity of the air in the entire building 10 also increases according to the humidity of the outside air, and it is assumed that the humidity of the outside air is higher than that of the room where the washed clothes are hung out to dry, especially during rainy weather or the rainy season. In such a situation, it is difficult to transport air suitable for drying clothes from the first space 11 to the second space 12. Therefore, when the humidity of the outside air is higher than a certain value, the blower 30 is not operated, and when the humidity of the outside air increases to a certain value or higher while the blower 30 is operating, the operation is stopped. This makes it possible to suppress unnecessary operation of the blower 30 and reduce power consumption.

[0030] The operation of the blower device 30 may be started or stopped by an instruction from the user. That is, the start condition and / or the stop condition may include an instruction from the user. The user can instruct the start or stop of the operation of the blower device 30, for example, by operating a remote control (not shown) or a mobile terminal such as a smartphone (not shown) held by the user. In this case, regardless of whether the start condition based on the detection result of the environmental sensor 60 described above is satisfied, when the user performs an operation to start the operation of the blower device 30, the control unit 112 of the control device 100 starts the operation of the blower device 30. Also, regardless of whether the stop condition based on the detection result of the environmental sensor 60 described above is satisfied, when the user performs an operation to stop the operation of the blower device 30, the control unit 112 of the control device 100 stops the operation of the blower device 30.

[0031] The blower device 30 may include an inverter and may be capable of variably controlling the rotation speed of the fan. In this case, the control unit 112 of the control device 100 may change the amount of air sent by the blower device 30 by changing the rotation speed of the fan in accordance with the detection result of the environment sensor 60. Specifically, for example, the control unit 112 increases the amount of air sent by the blower device 30 as the increase in humidity in the second space 12 within the first reference time increases. As another example, the control unit 112 increases the amount of air sent by the blower device 30 as the time until the increase in humidity in the second space 12 reaches or exceeds the first reference humidity decreases.

[0032] Next, an example of the operation of the air blowing system according to this embodiment will be described with reference to the flow diagram of Fig. 5. First, in a state in which the operation of the air blowing device 30 is stopped, in step S11, the information acquisition unit 111 of the control device 100 acquires the detection result of the environment sensor 60 and a user instruction. Then, in the following step S12, the control unit 112 of the control device 100 judges whether or not the above-mentioned start condition is satisfied. If the start condition is not satisfied, the control device 100 returns to step S11 and continues the process. On the other hand, if the start condition is satisfied, the control device 100 next performs the process of step S13.

[0033] In step S13, the control unit 112 of the control device 100 starts the operation of the blower device 30. In the following step S14, the control unit 112 of the control device 100 determines whether or not the above-mentioned stop condition is satisfied. If the stop condition is not satisfied, the control device 100 continues the operation of the blower device 30 until the stop condition is satisfied. Then, if the stop condition is satisfied, the control device 100 next performs the process of step S15. In step S15, the control unit 112 of the control device 100 stops the operation of the blower device 30. When the process of step S15 is completed, the series of operations ends.

[0034] According to the air blowing system configured as described above, the temperature and humidity environments in the second space 12 can be improved. This improves the comfort of the user. In particular, it is possible to improve the drying efficiency of clothes hung to dry indoors in the second space 12. In other words, it is possible to promote efficient drying of laundry hung to dry indoors in a building.

[0035] In the air blowing system according to this embodiment, the start condition for the operation of the air blowing device 30 may be satisfied when the start condition described above is satisfied or when the washing machine installed in the building 10 is operated. In this case, the control device 100 is provided with an equipment operation state acquisition unit (not shown). The equipment operation state acquisition unit of the control device 100 communicates directly with the washing machine installed in the building 10 or communicates via a HEMS or the like to acquire the operation state of the washing machine. Then, the control unit 112 of the control device 100 starts the operation of the air blowing device 30 when the start condition described above is satisfied or when the washing machine is operated. When the washing machine is operated, there is a possibility that the washed clothes or the like are hung to dry indoors in, for example, the second space 12 or the like in the building 10. By operating the air blowing device 30 in such a case, the humidity in the building 10 can be made uniform in advance, and the drying of the washed clothes or the like can be promoted.

[0036] Embodiment 2 A second embodiment of the present disclosure will be described with reference to Figs. 6 to 18. Fig. 6 is a plan view showing a schematic example of a building to which an air conditioning system is applied. Fig. 7 is a cross-sectional view taken along line AA in Fig. 6. Fig. 8 is a block diagram showing the configuration of a control system for the air conditioning system. Fig. 9 is a diagram showing airflow when a blower in the air conditioning system is stopped. Fig. 10 is a diagram showing airflow when a blower in the air conditioning system is operating. Fig. 11 is a flow diagram showing an example of the operation of the air conditioning system. Fig. 12 is a block diagram showing the configuration of a control system for a modified example of the air conditioning system. Figs. 13 to 18 each show an example of a display screen in a device operation application for the air conditioning system.

[0037] The second embodiment described here relates to an air conditioning system in which an air conditioner is added to the air blowing system of the first embodiment described above. The air conditioning system of the second embodiment will be described focusing on the differences from the first embodiment. Configurations that are not described are basically the same as those of the first embodiment. In the following description, configurations that are the same as or correspond to those of the first embodiment will be described with the same reference numerals as those used in the description of the first embodiment, as a general rule.

[0038] The air conditioning system according to this embodiment includes an air conditioner 40, as shown in Figs. 6 and 7. The air conditioner 40 conditions the air in the first space 11, which is a living room. In the illustrated example, an indoor unit of the air conditioner 40 is installed in the first space 11. An outdoor unit of the air conditioner 40, not shown, is installed outdoors of the building 10. The air conditioner 40 is capable of, for example, cooling operation, heating operation, fan operation, dehumidification operation, and cooling and dehumidification operation. The cooling and dehumidification operation is an operation in which cooling and dehumidification are performed simultaneously. The air conditioner 40 starts operation by the user operating a remote control or the like. The air conditioner 40 performs cooling operation, dehumidification operation, cooling and dehumidification operation, or heating operation so that the temperature of the first space 11 becomes the set temperature and set humidity set by the user.

[0039] 6 and 7, the air conditioning system further includes an exhaust device 52. In the illustrated example, the exhaust device 52 is provided on the outer wall of the second space 12. The exhaust device 52 includes a fan, and when it is operated, it exhausts the air in the second space 12 to the outside of the building 10. Furthermore, in the configuration example shown in FIG. 6, an air supply device 51 is provided on the outer wall of the first space 11. The air supply device 51 is an air supply port for taking in the air outside the building 10 (external air) into the first space 11. Although not mentioned in the description of the air supply system of the first embodiment, one or both of the exhaust device 52 and the air supply device 51 may be provided in the air supply system of the first embodiment.

[0040] In the air conditioning system according to this embodiment, the control device 100 controls not only the operation of the blower device 30 but also the operation of the air conditioner 40. As shown in FIG. 8, the control device 100 is connected to the air conditioner 40 so as to be able to communicate with it. The information acquisition unit 111 of the control device 100 acquires information relating to the operation status of the air conditioner 40 from the air conditioner 40. The information relating to the operation status of the air conditioner 40 may include, for example, whether the air conditioner 40 is operating or stopped, the operation mode of the air conditioner 40, i.e., cooling operation, heating operation, blowing operation, dehumidification operation, cooling and dehumidification operation, etc., the set temperature (during cooling operation, heating operation, or cooling and dehumidification operation), the set humidity (during dehumidification operation, cooling and dehumidification operation), the wind direction, the air volume, etc.

[0041] Furthermore, the control device 100 is communicatively connected to the exhaust device 52. An information acquisition unit 111 of the control device 100 acquires information relating to the operating status of the exhaust device 52 from the exhaust device 52. The information relating to the operating status of the exhaust device 52 may include, for example, whether the exhaust device 52 is operating or stopped, and if it is operating, the exhaust air volume, etc.

[0042] The start conditions for the operation of the blower device 30 in the air conditioning system according to this embodiment will be described below with some specific examples. In a first example of the start conditions for the operation of the blower device 30 in the air conditioning system according to this embodiment, the start condition is met when any of the following conditions is met.

[0043] The humidity in the second space 12 has increased to or above the first reference humidity within the first reference time. After the air conditioner 40 started operating, a preset third reference time has elapsed. The humidity in the first space 11 is equal to or lower than the humidity in the second space 12.

[0044] In this case, the environmental sensor 60 can detect at least the humidity of the air in each of the first space 11 and the second space 12. That is, the environmental information acquisition means acquires information regarding the humidity in the first space 11 and information regarding the humidity in the second space 12. Then, the control unit 112 of the control device 100 starts the operation of the blower device 30 when any of the above conditions is established based on the information acquired by the environmental information acquisition means. The third reference time is, for example, 15 minutes.

[0045] In a second example of a start condition for the operation of the blower device 30 in the air conditioning system according to this embodiment, the start condition is met when any one of the following conditions is met.

[0046] The humidity in the second space 12 has increased to or above the first reference humidity within the first reference time. After the air conditioner 40 started operating, the aforementioned third reference time has elapsed. The difference between the set temperature of the air conditioner 40 and the temperature of the first space 11 is equal to or less than a preset first reference temperature.

[0047] In this case, the environmental sensor 60 can detect at least the temperature of the air in the first space 11 and the humidity of the air in the second space 12. That is, the environmental information acquisition means acquires information related to the temperature of the air in the first space 11 and information related to the humidity in the second space 12. Furthermore, the information acquisition unit 111 acquires information related to the set temperature of the air conditioner 40 from the air conditioner. Then, based on the information acquired by the environmental information acquisition means, the control unit 112 of the control device 100 starts the operation of the blower device 30 when any of the above conditions is met. The first reference temperature is, for example, 1°C.

[0048] The control device 100 stops the operation of the blower device 30 when a preset stop condition is satisfied during the operation of the blower device 30. That is, the blower device 30 stops transporting air from the first space 11 to the second space 12 when the stop condition is satisfied during the operation of the blower device 30. As an example of a stop condition for the operation of the blower device 30, the stop condition is satisfied when any of the following conditions is satisfied.

[0049] The outdoor humidity has increased to or exceeds the third standard humidity level within the second standard time period. After the operation of the blower device 30 has started, a preset fourth reference time has elapsed. The humidity in the second space 12 remains below the fourth reference humidity for more than the fifth reference time.

[0050] In this case, the environmental sensor 60 can detect the humidity of the outside air and the humidity of the second space 12. That is, the environmental information acquisition means acquires information related to the humidity of the outside air and the humidity of the second space 12. Then, the control unit 112 of the control device 100 stops the operation of the blower device 30 when any of the above conditions is met based on the information acquired by the environmental information acquisition means. The fourth reference time is, for example, 8 hours. The fourth reference humidity is, for example, 60%. The fifth reference time is, for example, 10 minutes.

[0051] In the air conditioning system according to this embodiment, the control unit 112 of the control device 100 may change the operation of one or both of the blower device 30 and the air conditioner 40 based on the information acquired by the information acquisition unit 111. When changing the operation of the blower device 30, the blower device 30 can change the airflow by changing the rotation speed of the fan, as described above. For example, the control unit 112 changes the airflow of the blower device 30 according to the humidity of the first space 11 and the humidity of the second space 12. For example, the control unit 112 increases the airflow of the blower device 30 as the difference between the humidity of the first space 11 and the humidity of the second space 12 increases. In addition, for example, the control unit 112 changes one or both of the airflow and the set temperature of the air conditioner 40 according to the humidity of the first space 11 and the humidity of the second space 12. In this case, the environment sensor 60 can detect the humidity of the first space 11 and the humidity of the second space 12.

[0052] As another example, the control unit 112 may change the airflow rate of the blower 30 depending on the temperature of the first space 11 and the temperature of the second space 12. For example, the control unit 112 increases the airflow rate of the blower 30 as the difference between the temperature of the first space 11 and the temperature of the second space 12 increases. The control unit 112 may also change one or both of the airflow rate and the set temperature of the air conditioning device 40 depending on the temperature of the first space 11 and the temperature of the second space 12. In this case, the environmental sensor 60 is capable of detecting the temperature of the first space 11 and the temperature of the second space 12.

[0053] As yet another example, the control unit 112 may change the airflow rate of the blower 30 according to the temperature of the first space 11 and the set temperature of the air conditioning device 40. For example, the control unit 112 increases the airflow rate of the blower 30 as the difference between the temperature of the first space 11 and the set temperature of the air conditioning device 40 decreases. In this case, the environmental sensor 60 is capable of detecting the temperature of the first space 11.

[0054] FIG. 9 is a diagram showing the main air flow when the blower 30 is stopped. In FIG. 9, the air flow when the air conditioner 40 and the exhaust device 52 are operating and the blower 30 is stopped is shown by a dashed line and an arrow. As shown in FIG. 9, first, outside air flows into the first space 11 through the air supply device 51, and the air in the first space 11 is heated or cooled by the air conditioner 40. The air in the first space 11 flows into the third space 13 through a gap (undercut, etc.) or a vent hole in the first door 14. Then, the air that has flowed into the third space 13 flows into the second space 12 through a gap (undercut, etc.) or a vent hole in the second door 15, and is discharged to the outdoors from the exhaust device 52.

[0055] Here, when the air conditioning device 40 and the exhaust device 52 are operating and the blower device 30 is stopped, the relationship between the pressure P1 in the first space 11, the pressure P2 in the second space 12, and the pressure P3 in the third space 13 is P1>P3>P2. The pressure P1 in the first space 11 into which outside air flows in through the air supply device 51 is almost equal to the atmospheric pressure, so the pressure P3 is lower than the atmospheric pressure. Therefore, the outside air flows into the third space 13 through a gap or a vent in the entrance door 16, and flows into the second space 12 through a gap (undercut, etc.) or a vent in the second door 15.

[0056] Next, a case where the blower 30 is operating will be described. FIG. 10 is a diagram showing the main air flow when the blower 30 is operating. In FIG. 10, the air flow when the air conditioner 40 and the exhaust device 52 are operating and the blower 30 is operating is shown by broken lines and arrows. As shown in FIG. 10, first, outside air flows into the first space 11 through the air supply device 51, and the air in the first space 11 is heated or cooled by the air conditioner 40. The air in the first space 11 flows into the duct 20 through the intake port 21 by the blower 30, and is blown into the second space 12 through the exhaust port 22. Then, the air in the second space 12 is exhausted to the outside from the exhaust device 52. In addition, in the third space 13, outside air flows into the third space 13 through a gap or a vent in the entrance door 16, and flows into the second space 12 through a gap (undercut, etc.) or a vent in the second door 15.

[0057] In the above-described manner, when the blower 30 is operated, in addition to the effect of the first embodiment, the air heated or cooled by the air conditioning device 40 can be sent to the second space 12 without passing through other spaces (particularly spaces where air conditioning is not performed). For this reason, for example, when washed clothes are hung out to dry in the second space 12, air more suitable for drying the clothes can be sent, and the drying of the clothes can be further promoted. In addition, by sending air into the second space 12 by operating the blower 30, the efficiency of ventilation by the exhaust device 52 installed in the second space 12 is improved, and moisture released from the clothes is actively discharged to the outside, further promoting the drying of the clothes.

[0058] Next, an example of the operation of the air blowing system according to this embodiment will be described with reference to the flow diagram of Fig. 5. First, in a state in which the operation of the air blowing device 30 is stopped, in step S21, the information acquisition unit 111 of the control device 100 acquires the detection result of the environment sensor 60, the operating state of the air conditioning device 40, the exhaust air volume of the exhaust device 52, and user instructions. Then, in the following step S22, the control unit 112 of the control device 100 judges whether or not the above-mentioned start condition is satisfied. If the start condition is not satisfied, the control device 100 returns to step S21 and continues the process. On the other hand, if the start condition is satisfied, the control device 100 next performs the process of step S23.

[0059] In step S23, the control unit 112 of the control device 100 starts the operation of the blower device 30. In the following step S24, the control unit 112 of the control device 100 judges whether or not the above-mentioned stop condition is satisfied. If the stop condition is not satisfied, the control device 100 continues the operation of the blower device 30 until the stop condition is satisfied. Then, if the stop condition is satisfied, the control device 100 next performs the process of step S25. In step S25, the control unit 112 of the control device 100 stops the operation of the blower device 30. When the process of step S25 is completed, the series of operations ends.

[0060] Next, a modified example of the air conditioning system according to this embodiment will be described with reference to Figs. 12 to 18. In this modified example, the information acquisition unit 111 of the control device 100 can communicate with the cloud server 201 via a communication line such as the Internet. The cloud server 201 provides a specific service by a collection of multiple server devices. In the example described here, the cloud server 201 mediates when the control device 100 acquires information from an external information server 202. The cloud server 201 also mediates data exchange between the control device 100 and a terminal device 203 owned by a user. Note that the information acquisition unit 111 may acquire information from the environmental sensor 60 via the cloud server 201 or directly from the environmental sensor 60.

[0061] The external information server 202 is a server that provides, for example, weather information. The information acquisition unit 111 of the control device 100 acquires weather information from the external information server 202 via the cloud server 201. The weather information includes physical quantities related to the external environment.

[0062] The information acquisition unit 111 of the control device 100 acquires information from the terminal device 203 and the external information server 202 via the cloud server 201, and based on the information, the control unit 112 controls the operation of the blower device 30. The terminal device 203 is, for example, a smartphone, a tablet terminal, a smart watch, a smart TV, a smart speaker, etc. An application for device operation is installed in the terminal device 203. The user can control each device using the application for device operation, and the user can operate the operating state of each device as desired. In addition, the operating state of each device, the environmental sensor 60, and data acquired from the external information server 202 may be displayed on a display screen by the application for device operation executed on the terminal device 203.

[0063] Fig. 13 shows an example of a screen displaying a list of the operating status of each device by a device operation application of the terminal device 203. Fig. 14 shows an example of a display screen when a specific device (blower device 30 in the illustrated example) is operated by a device operation application of the terminal device 203. Fig. 15 shows an example of a screen displaying measurement data of the environmental sensor 60 by a device operation application of the terminal device 203.

[0064] Furthermore, if the external information server 202 is a server that provides weather information, the control unit 112 may use the outside air temperature and humidity or weather-related information included in the weather information acquired from the external information server 202 to determine one or both of the start and stop conditions for the operation of the blower device 30. In this case, the outside air temperature and humidity or a condition related to the weather is added to one or both of the start and stop conditions for the operation of the blower device 30. For example, when a condition related to the weather is added to the start conditions, the operation start condition for the blower device 30 is set to be that any of the start conditions described above is satisfied and that the weather is fine.

[0065] The control unit 112 controls the operation, stopping, and airflow volume of the blower 30 when in operation, based on the operation information of the air conditioning apparatus 40 acquired by the information acquisition unit 111. The control unit 112 may control the airflow volume of the blower 30 to a preset airflow volume, regardless of the exhaust airflow volume of the exhaust device 52. Here, the airflow volume of the blower 30 is set to an airflow volume that satisfies the ventilation rate of 0.5 times / h in the building 10, for example.

[0066] Furthermore, when the weather information indicates that the weather is fine and the outside air temperature is particularly low (for example, in winter), it is possible to operate the blower 30 without operating the air conditioner 40, since it is expected that the temperature in the first space 11 will rise due to solar radiation. The air in the first space 11 that has become hot due to solar radiation can be transported to the second space 12 by operating the blower 30, thereby enabling temperature control, and power consumption can be reduced by not using the air conditioner 40.

[0067] Furthermore, the operation of the air conditioner 40 and the blower 30 may be controlled according to the temperature and humidity of the first space 11. In this case, the blower 30 may be operated without operating the air conditioner 40, provided that one or both of the following conditions are met: the temperature of the first space 11 is equal to or higher than a preset reference value, and the humidity of the first space 11 is equal to or lower than a preset reference value. In this way, the temperature of the second space 12 can be regulated while reducing power consumption by not using the air conditioner 40.

[0068] Also, the control device 100 may acquire information on a weather forecast from among the weather information, calculate a clothes drying predicted time according to the weather conditions, and notify the user. In this case, the control device 100 includes a clothes drying time prediction unit. The clothes drying time prediction unit predicts the clothes drying time of the laundry hung out in the second space 12 using the weather information acquired by the information acquisition unit 111, such as the predicted maximum temperature, weather, predicted humidity, predicted wind speed, and the like. The clothes drying time prediction unit may also predict the clothes drying time of the laundry hung out in the second space 12 based on the detection results of the environment sensor 60 acquired by the information acquisition unit 111, such as the temperature and humidity of the first space 11 and the temperature and humidity of the second space 12. Then, the predicted result of the clothes drying time is displayed, for example, on a display screen by a device operation application of the terminal device 203. At this time, information on the change in the clothes drying time due to the change in the weather may be notified to the user. For example, when the weather suddenly changes in the direction of increasing the clothes drying time, such as sudden rain or a drop in temperature, the clothes drying predicted time may be changed and notified to the user. FIG. 16 shows an example of a display screen by the device operation application of the terminal device 203 in this case.

[0069] Furthermore, information regarding the amount of pollutants in the outdoor air (pollen, PM2.5, yellow sand, etc.) may be obtained from the weather information, and if the amount of outdoor pollutants is expected to be equal to or greater than a certain value, the user may be recommended to dry clothes indoors. The recommendation in this case may be displayed, for example, on a display screen of a device operation application of the terminal device 203. An example of a display screen of the device operation application of the terminal device 203 in this case is shown in FIG. 17. This makes it possible to prevent deterioration of comfort due to pollutants in the outdoor air.

[0070] During the operation of the blower device 30, if the information acquisition unit 111 cannot acquire the environmental information used for control, for example, the environmental information used for determining the above-mentioned stop condition and for determining whether to change the operation content of the blower device 30, due to a failure of the environmental sensor 60, a network communication failure, etc., the control unit 112 may continue the operation of one or both of the air conditioning device 40 and the blower device 30. In this case, the operation content of the air conditioning device 40 and the blower device 30 is maintained without change from, for example, the one at the time of the failure to acquire the environmental information. In other words, the blower device 30 continues to operate when the environmental information acquisition means cannot acquire the environmental information during operation. As a result, even if the information used for control cannot be acquired due to an error, the system does not stop, and the risk of the clothes remaining undried or being half-dried can be reduced when clothes are dried in the second space 12.

[0071] During the operation of the blower 30, if the information acquisition unit 111 cannot acquire the environmental information used for control due to a failure of the environmental sensor 60, a network communication failure, or the like, the user may be asked whether or not to continue the operation of one or both of the air conditioning device 40 and the blower 30. In this case, the control device 100 notifies the user, for example, on the display screen of the terminal device 203, that the information of the environmental sensor 60, etc. cannot be acquired, and notifies the user of a message or the like for confirming whether or not to continue the operation of the air conditioning device 40 and the blower 300. An example of a display screen by the device operation application of the terminal device 203 in this case is shown in FIG. 18. In the example shown in the figure, buttons "Yes" and "No" are displayed together with the message. The user can instruct whether or not to continue the operation of the air conditioning device 40 and the blower 30 by operating one of these buttons. In this case, the control device 100 is provided with a confirmation unit. The confirmation unit causes the terminal device 203 to display a message for confirming with the user whether or not to continue the operation of the blower device 30 when the environmental information acquisition means fails to acquire environmental information while the blower device 30 is operating. The confirmation unit of the control device 100 and the terminal device 203 constitute confirmation means for confirming with the user whether or not to continue the operation of the blower device 30 when the environmental information acquisition means fails to acquire environmental information while the blower device 30 is operating.

[0072] In the air blowing system and air conditioning system according to the present disclosure, the air blowing device 30 may be configured to stop operating during a stop time period input by the user during a day. In this case, the user can input the stop time period by operating an input means such as the remote control, mobile terminal, or terminal device 203 described above. The control device 100 is provided with a schedule setting unit (not shown). The schedule setting unit of the control device 100 sets a schedule for stopping the air blowing device 30 during the stop time period input by the user. The control unit 112 of the control device 100 controls the start and stop of the operation of the air blowing device 30 according to the schedule set by the schedule setting unit. Even if the start conditions described above are satisfied, the control unit 112 of the control device 100 stops the operation of the air blowing device 30 when the current time falls within the stop time period during a day.

[0073] Also, the user may be allowed to input the operation time period by operating an input means such as the remote control, mobile terminal, or terminal device 203 described above. In this case, the schedule setting unit of the control device 100 sets a schedule for the operation of the blower device 30 during the operation time period input by the user. Then, the control unit 112 of the control device 100 controls the start and stop of the operation of the blower device 30 according to the schedule set by the schedule setting unit. In this way, the blower device 30 can be automatically operated according to a schedule desired by the user.

[0074] In the air blowing system and air conditioning system according to the present disclosure, the exhaust device 52 may be provided in one or both of the first space 11 and the second space 12. In this case, the air blowing volume of the air blowing device 30 should be greater than the total exhaust air volume of the exhaust device 52. In this way, the air blowing device 30 can sufficiently transport air from the first space 11 to the second space 12, and the humidity can be made uniform.

[0075] Embodiment 3 A third embodiment of the present disclosure will be described with reference to Fig. 19 and Fig. 20. Fig. 19 is a plan view showing an example of a building to which an air-conditioning system is applied. Fig. 20 is a diagram showing an air flow when a blower in the air-conditioning system is operating.

[0076] The third embodiment described here is an air blowing system according to the first embodiment or an air conditioning system according to the second embodiment, which transports air from the first space to the third space as well as the second space. The air conditioning system according to the third embodiment will be described using an example based on the second embodiment, with a focus on the differences from the second embodiment. Configurations whose description is omitted are basically the same as those of the first or second embodiment. In the following description, configurations similar to or corresponding to those of the first or second embodiment will be described, in principle, with the same reference numerals as those used in the description of the first or second embodiment.

[0077] As shown in FIG. 19, the air conditioning system according to this embodiment includes an air conditioner 40. The air conditioner 40 conditions the air in the first space 11, which is a living room. In the illustrated example, an indoor unit of the air conditioner 40 is installed in the first space 11. An outdoor unit (not shown) of the air conditioner 40 is installed outdoors of the building 10. The air conditioner 40 is capable of, for example, cooling operation, heating operation, fan operation, dehumidification operation, and cooling and dehumidification operation. The cooling and dehumidification operation is an operation in which cooling and dehumidification are performed simultaneously. The air conditioner 40 starts operation by the user operating a remote control or the like. The air conditioner 40 performs cooling operation, dehumidification operation, cooling and dehumidification operation, or heating operation so that the temperature of the first space 11 becomes the set temperature and set humidity set by the user.

[0078] 19, the air conditioning system further includes an exhaust device 52. In the illustrated example, the exhaust device 52 is provided on the outer wall of the second space 12. The exhaust device 52 includes a fan, and when operated, exhausts the air in the second space 12 to the outside of the building 10. Furthermore, in the configuration example shown in FIG. 19, an air supply device 51 is provided on the outer wall of the first space 11. The air supply device 51 is an air supply port for taking in air outside the building 10 (external air) into the first space 11.

[0079] As shown in FIG. 19, a duct 20 is provided in the ceiling of the first space 11, the second space 12, and the third space 13. One end of the duct 20 is connected to an intake port 21 formed in the ceiling of the first space 11. The other end of the duct 20 is branched into two. One of the branches at the other end of the duct 20 is connected to an outlet 22 (first outlet) formed in the ceiling of the second space 12. The other of the branches at the other end of the duct 20 is connected to a second outlet 23 formed in the ceiling of the third space 13. An air passage is formed in the duct 20 to communicate the first space 11 with the second space 12 and the third space 13. A blower 30 is provided on the intake port 21 side of the branched portion of the duct 20. A fan is built in the blower 30.

[0080] When the blower 30 operates, that is, when the fan of the blower 30 operates, air currents are generated in the air passage in the duct 20, flowing from the first space 11 side toward the second space 12 side and the third space 13 side. When the blower 30 operates, air in the first space 11 is sucked into the duct 20 through the intake port 21. The air sucked into the duct 20 branches and is blown out from the outlet 22 into the second space 12, and from the second outlet 23 into the third space 13. In this way, the blower 30 transports the air in the first space 11 to each of the second space 12 and the third space 13.

[0081] In addition, it is possible to select the target space for air transport by providing an air path varying means (not shown) such as a damper opening and closing mechanism in at least one of the inside of the duct 20, the air outlet 22, and the second air outlet 23. This makes it possible to limit the destination of the air in the first space 11 according to the indoor temperature, humidity, and outside air conditions, thereby enabling efficient temperature control within the space and reducing energy consumption.

[0082] The control device 100 controls the exhaust air volume of the exhaust device 52 based on the operating state of the blower device 30 and the air volume of the blower device 30. Specifically, when the blower device 30 is stopped, the control unit 112 controls the exhaust device 52 to a preset initial air volume. Also, when the blower device 30 is operating, the control unit 112 controls the exhaust air volume of the exhaust device 52 to be lowered to be smaller than the air volume of the blower device 30. As a result, when the blower device 30 is operating, the relationship between the pressure P1 of the first space 11, the pressure P2 of the second space 12, and the pressure P3 of the third space 13 is P3>P1>P2. That is, in this embodiment, the control device 100 functions as an adjustment unit that adjusts the pressure of each space so that the pressure P3 of the third space 13 is greater than the pressure P1 of the first space 11.

[0083] Moreover, even when the blower 30 is operated, if the blowing volume of the blower 30 is equal to or less than the exhaust volume of the exhaust device 52, the relationship between the pressures P1, P2 and P3 described above is P1>P3>P2, resulting in the air flow shown in Fig. 9. In this case as well, outside air flows into the third space 13 through the gap in the entrance door 16 or through the vent, etc., and therefore the effect of improving the thermal environment by blowing air from the first space 11 into the third space 13 is reduced, and the comfort of users in the building 10 is also reduced.

[0084] Therefore, in this embodiment, the air conditioning system or the air blowing system is provided with an adjustment means for adjusting the pressure of each space so that the pressure P3 of the third space 13 is greater than the pressure P1 of the first space 11. In the configuration example described here, the control unit 112 functions as the adjustment means. The control unit 112 controls the rotation speed of the air blowing device 30 so that the air volume of the air blowing device 30 is greater than the exhaust air volume of the exhaust device 52. This makes it possible to make the pressure P3 of the third space 13 greater than the pressure P1 of the first space 11. More specifically, the relationship between the pressures P1, P2, and P3 can be P3>P1>P2. This makes the pressure of the third space 13 greater than the atmospheric pressure, so that it is possible to suppress the inflow of outside air into the third space 13 from the gap in the entrance door 16 or the air vent.

[0085] Next, referring to FIG. 20, the flow of air in the room when the blower 30 is operating will be described. FIG. 20 is a diagram showing the main air flow when the blower 30 is operating. In FIG. 20, the air conditioner 40 and the exhaust device 52 are operating, and the air flow when the blower 30 is operating is shown by dashed lines and arrows. As shown in FIG. 20, first, outside air flows into the first space 11 through the air supply device 51, and the air in the first space 11 is heated or cooled by the air conditioner 40. The air in the first space 11 flows into the duct 20 through the intake port 21 by the operation of the blower 30, and is blown into the second space 12 through the outlet port 22. In addition, the air in the first space 11 is branched in the duct 20 and is also blown into the third space 13 through the second outlet port 23. Then, the air in the second space 12 is exhausted to the outdoors from the exhaust device 52. Moreover, the air in the third space 13 flows into the second space 12 through a gap (such as an undercut) in the second door 15, a vent hole, or the like.

[0086] As described above, when the blower 30 is operated, air heated or cooled by the air conditioner 40 can be sent to the second space 12, and by also blowing air to the third space 13, the third space 13 becomes positively pressurized relative to the outside air pressure, and air inflow from the front door 16 can be suppressed. This prevents the thermal environment from deteriorating due to the influence of the outside air, even when the outside air is low temperature or high humidity, creating an environment unsuitable for drying clothes, and as a result, the air conditioning efficiency of the second space 12 is improved, and clothes drying can be further promoted.

[0087] In the above description, the outdoors of the building 10 may include not only the outside of the building 10 but also a non-air-conditioned space such as a parking lot within the building 10. In this case, the outside air may include not only the air outside the building 10 but also the air in the non-air-conditioned space.

[0088] FIG. 21 is a diagram showing an example of a configuration for realizing the functions of the control device 100 according to the present disclosure. The functions of the control device 100 are realized, for example, by a processing circuit. The processing circuit may include a processor 101 and a memory 102. The processing circuit may be dedicated hardware 103. A part of the processing circuit may be formed as the dedicated hardware 103, and the processing circuit may further include the processor 101 and the memory 102. In the example shown in the figure, a part of the processing circuit is formed as the dedicated hardware 103. Also, in the example shown in the figure, the processing circuit further includes the processor 101 and the memory 102.

[0089] The processing circuitry, part of which is at least one dedicated hardware 103, may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. If the processing circuitry comprises at least one processor 101 and at least one memory 102, the functionality of the control device 100 is realized by software, firmware, or a combination of software and firmware.

[0090] The software and firmware are written as programs and stored in memory 102. Processor 101 realizes the functions of each unit by reading and executing the programs stored in memory 102. Processor 101 is also called a CPU (Central Processing Unit), central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. Memory 102 corresponds to, for example, non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM, or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD.

[0091] In this way, the processing circuit of the control device 100 can realize each function of the control device 100 by hardware, software, firmware, or a combination of these. When the processing circuit of the control device 100 includes at least the processor 101 and the memory 102, the processor 101 executes a program stored in the memory 102 in the control device 100, and the hardware and software of the control device 100 work together to realize the functions of each part of the control device 100. Note that the air blowing system and the air conditioning system are not limited to a configuration in which the operation is controlled by a single control device 100. The operation of the air blowing system and the air conditioning system may be controlled by multiple devices working together. Also, the control device 100 may be built into the air blowing device 30 or the air conditioning device 40.

[0092] In addition, in the present disclosure, the respective embodiments may be arbitrarily combined without departing from the spirit of the present disclosure.
