[Diagram 2] FIG. 2 is a diagram showing the air flow caused by the ventilation system of FIGS. [Diagram 3] 3(a)-(b) are diagrams showing the configuration of a ventilation system according to the first modification. [Figure 4] 4(a)-(b) are diagrams showing the configuration of a ventilation system according to the second modification. [Diagram 5] 5(a)-(d) are diagrams showing the configuration of a ventilation system according to the third modification. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0011] Figures 1(a)-(e) show the configuration of the air blowing system 1000. Figure 1(a) shows a front view of the building 10 as viewed from the outdoor 12 side, and Figure 1(b) shows a perspective view of the building 10 as viewed from the outdoor 12 side. Figure 1(c) shows a perspective view of the B-B cross section of Figure 1(a), Figure 1(d) shows a B-B cross section of Figure 1(a), and Figure 1(e) shows an enlarged view of A of Figure 1(d).

[0012] The building 10 is, for example, an apartment building or other collective housing, but may also be a detached house or an office. An exterior wall 20 of the building 10 is a boundary between an outdoor area 12 and an indoor area 14, with the outside of the exterior wall 20 being the outdoor area 12 and the inside of the exterior wall 20 being the indoor area 14. The surface of the exterior wall 20 facing the outdoor area 12 is an outdoor surface 22, and the surface of the exterior wall 20 facing the indoor area 14 is an indoor surface 24.

[0013] An opposing wall 30 is erected at a position separated from the exterior wall 20 in the outdoor area 12 of the building 10. The opposing wall 30 is, for example, a handrail. The underside of the opposing wall 30 is connected to the underside of the building 10 by a connecting floor 40. A space of a balcony 50 is formed between the exterior wall 20, the opposing wall 30, and the connecting floor 40. In addition, the balcony 50 is separated from the adjacent dwelling unit by a boundary wall 42.

[0014] The air blowing system 1000 blows air into the space of the balcony 50. The air blowing system 1000 includes a blower 100, an exhaust duct 110, an exhaust cover 120, a first through-hole 130, and a second through-hole 140.

[0015] The blower 100 is disposed in the ceiling portion of the room 14. An indoor air inlet 102 is provided on the underside of the blower 100, and air from the room 14 is sucked in through the indoor air inlet 102 by the operation of the blower 100.

[0016] An exhaust duct 110 extending from the blower 100 to the exterior wall 20 is disposed in the ceiling portion of the room 14. The exhaust duct 110 is a pipe capable of transporting air. The exhaust duct 110 is connected to an exhaust cover 120 from the indoor surface 24 side of the exterior wall 20. The exhaust cover 120 has a hollow box shape and is disposed on the outdoor surface 22 of the exterior wall 20. An exhaust outlet 122 is provided in the lower portion of the exhaust cover 120. The exhaust outlet 122 is an opening communicating with the exhaust duct 110. In this configuration, the blower 100 transports the sucked air from the exhaust duct 110 to the exhaust cover 120. The exhaust cover 120 blows out air from the exhaust outlet 122.

[0017] The first through hole 130 and the second through hole 140 penetrate between the outdoor surface 22 and the indoor surface 24 of the exterior wall 20. The first through hole 130 is disposed above the exhaust air outlet 122, and the second through hole 140 is disposed below the first through hole 130, particularly below the exhaust air outlet 122. The opening of the first through hole 130 on the outdoor surface 22 is the first air supply port 132, and the opening of the second through hole 140 on the outdoor surface 22 is the second air supply port 142. By blowing out air from the exhaust air outlet 122, the first through hole 130 supplies air from the outdoor surface 12 to the indoor surface 14 from the first air supply port 132, and the second through hole 140 supplies air from the outdoor surface 12 to the indoor surface 14 from the second air supply port 142.

[0018] Here, when the first through hole 130 is opened, the second through hole 140 is closed. For example, a lid (not shown) is attached to the opening of the second through hole 140 on the indoor surface 24 side. Also, when the first through hole 130 is closed, the second through hole 140 is opened. For example, a lid (not shown) is attached to the opening of the first through hole 130 on the indoor surface 24 side. That is, air from the outdoor area 12 is supplied to the indoor area 14 through one of the first through hole 130 and the second through hole 140.

[0019] FIG. 2 shows the air flow by the ventilation system 1000. FIG. 2 is a BB cross-sectional view of FIG. 1(a) similar to FIG. 1(d). The upper end portion of the opposing wall 30 is indicated as a "first position (P1)". The exhaust air outlet 122 of the exhaust cover 120 blows out air toward the upper end portion "first position (P1)" of the opposing wall 30. The air blown out from the exhaust air outlet 122 collides with the inner surface of the opposing wall 30 in the vicinity of the first position (P1) and then descends along the inner surface of the opposing wall 30. The air also moves toward the outdoor surface 22 along the connecting floor 40 and flows upward along the outdoor surface 22. Therefore, the veranda 50 formed by the opposing wall 30, the connecting floor 40, and the outdoor surface 22 is filled with air blown out from the exhaust air outlet 122. As a result, the space of the veranda 50 is zoned.

[0020] (Variation 1) In the air blowing system 1000 according to the first modification, it is possible to adjust the volume of air blown out from the exhaust outlet 122 and the direction of the air blown out from the exhaust outlet 122. The following mainly describes the differences from the previous modifications.

[0021] 3(a)-(b) show the configuration of a ventilation system 1000. As shown in Fig. 3(a), the ventilation system 1000 includes a blower 100, an exhaust cover 120, and an air conditioner 150. The blower 100 and the exhaust cover 120 are arranged in the same manner as in Figs. 1(a)-(e). The air conditioner 150 is arranged indoors 14, and adjusts the temperature and humidity of the air in the indoors 14.

[0022] Air conditioning device 150 includes an operation unit 152, a control unit 154, a storage unit 156, and a communication unit 158. Operation unit 152 is an interface capable of receiving from a user an instruction to perform cooling operation or heating operation in air conditioning device 150. Operation unit 152 can also receive an instruction to set the temperature and an instruction to set the humidity, but a description of this will be omitted here.

[0023] The control unit 154 controls the operation of the air conditioner 150. When the control unit 154 receives an instruction for cooling operation from the operation unit 152, it causes the air conditioner 150 to perform cooling operation. When the control unit 154 receives an instruction for heating operation from the operation unit 152, it causes the air conditioner 150 to perform heating operation.

[0024] The memory unit 156 stores tables to be used by the control unit 154. FIG. 3(b) shows the data structure of the tables stored in the memory unit 156. "Operation" indicates cooling operation or heating operation of the air conditioner 150. The "air volume: first air volume" of the blower 100 and the "air direction: first position (P1)" of the exhaust air outlet 122 correspond to the heating operation. The "air volume: second air volume" of the blower 100 and the "air direction: second position (P2)" of the exhaust air outlet 122 correspond to the cooling operation. The second air volume is larger than the first air volume. In addition, The second position (P2) is a position lower than the first position (P1). Return to FIG.

[0025] Control unit 154 refers to the table based on instructions received from operation unit 152, and determines the air volume of blower 100 and the air direction of exhaust outlet 122. Control unit 154 may determine only one of the air volume of blower 100 and the air direction of exhaust outlet 122. Control unit 154 causes communication unit 158 ​​to transmit information on the determined air volume to blower 100. Control unit 154 also causes communication unit 158 ​​to transmit information on the determined air direction to exhaust cover 120. Communication unit 158 ​​is capable of wireless communication.

[0026] Fan 100 has a communication function that enables communication with communication unit 158. Fan 100 receives information on the air volume, that is, information on the first air volume or the second air volume, from communication unit 158. When fan 100 receives information on the first air volume, it delivers air at the first air volume, and when fan 100 receives information on the second air volume, it delivers air at the second air volume.

[0027] Exhaust cover 120 has a communication function that enables communication with communication unit 158. Exhaust cover 120 receives information on the wind direction, that is, information on the first position (P1) or the second position (P2), from communication unit 158. When exhaust cover 120 receives information on the first position (P1), exhaust outlet 122 blows air toward the first position (P1). When exhaust cover 120 receives information on the second position (P2), exhaust outlet 122 blows air toward the second position (P2).

[0028] In Fig. 2, the second position (P2) is shown below the first position (P1). Generally, when the temperature of the outdoors 12 is high, the air conditioner 150 performs cooling operation. At that time, the temperature of the air blown out from the exhaust outlet 122 is lower than the temperature of the outdoors 12. In such a temperature relationship, the air blown out from the exhaust outlet 122 has a tendency to descend. Therefore, air is blown out toward the "first position (P1)" at the "first airflow rate."

[0029] On the other hand, when the temperature of the outdoors 12 is low, the air conditioner 150 performs heating operation. At that time, the temperature of the air blown out from the exhaust air outlet 122 is higher than the temperature of the outdoors 12. In such a temperature relationship, the air blown out from the exhaust air outlet 122 has a tendency to rise. Therefore, in order to make the air blown out from the exhaust air outlet 122 flow downward along the inner surface of the opposing wall 30, then move along the connecting floor 40 toward the outdoor surface 22, and rise along the outdoor surface 22, the air is blown out toward the "second position (P2)" at the "second airflow rate".

[0030] (Variation 2) Up to now, the first through hole 130 has been disposed above the exhaust outlet 122, and the second through hole 140 has been disposed below the exhaust outlet 122. However, there are cases where the first through hole 130 or the second through hole 140 cannot be disposed at such positions. In the air blowing system 1000 according to the second modification, covers are attached to the first through hole 130 and the second through hole 140. The following mainly describes the differences from the previous modifications.

[0031] 4(a)-(b) show the configuration of the air supply system 1000. FIG. 4(a) shows a front view of the building 10 as seen from the outdoor 12 side, similar to FIG. 1(a), and FIG. 4(b) shows a cross-sectional perspective view of FIG. 4(a) taken along CC. The first air supply cover 134 is disposed on the outdoor surface 22 of the exterior wall 20, and is connected to the first through-hole 130. The first air supply cover 134 has a first air supply port 132 facing upward. That is, air from the outdoor 12 is drawn in from the upper side of the first air supply cover 134. The second air supply cover 144 is disposed on the outdoor surface 22 of the exterior wall 20, and is connected to the second through-hole 140. The second air supply cover 144 has a second air supply port 142 facing downward. That is, air from the outdoor 12 is drawn in from the lower side of the second air supply cover 144.

[0032] (Variation 3) In the air blowing system 1000 according to the third embodiment, the exhaust cover 120 extends from one end (hereinafter referred to as the "first end") of the balcony 50 to the other end (hereinafter referred to as the "second end"). In other words, the shape of the exhaust cover 120 is different from that of the past. The following mainly describes the differences from the past.

[0033] 5(a)-(d) show the configuration of the air blowing system 1000. FIG. 5(a) shows a front view of the building 10 as seen from the outdoor 12 side, as in FIG. 1(a), FIG. 5(b) shows the inside of the exhaust cover 120 in FIG. 5(a), FIG. 5(c) shows a DD cross-sectional perspective view of FIG. 5(a), and FIG. 5(d) shows a DD cross-sectional view of FIG. 5(a). The exhaust cover 120 has a shape that extends from the first end 160 side of the balcony 50 to the second end 162 side along the outdoor surface 22 of the exterior wall 20. Therefore, the exhaust air outlet 122 is a slit that extends from the first end 160 side of the balcony 50 to the second end 162 side. The slit of the exhaust air outlet 122 is divided into multiple parts by multiple deflection plates 124. Further, a communication hole 136 is provided in the exhaust cover 120 , and the communication hole 136 is connected to the first through hole 130 .

[0034] According to this embodiment, the exhaust air outlet 122 of the exhaust cover 120 blows air toward the upper end portion of the opposing wall 30, so that the air can flow along the inner surface of the opposing wall 30, the connecting floor 40, and the outdoor surface 22. In addition, since the air flows along the inner surface of the opposing wall 30, the connecting floor 40, and the outdoor surface 22, the balcony 50 can be zoned. Furthermore, since the second through hole 140 is closed when the first through hole 130 is opened, the balcony 50 can be zoned while ventilating the indoors 14. Furthermore, since the second through hole 140 is opened when the first through hole 130 is closed, zoning can be performed with energy savings.

[0035] In addition, when the air conditioning device 150 performs a heating operation, the volume of air blown out is larger than when the air conditioning device 150 performs a cooling operation, so that the rising of the air can be suppressed. In addition, when the air conditioning device 150 performs a cooling operation, the air is blown out toward the lower side than when the air conditioning device 150 performs a cooling operation, so that the rising of the air can be suppressed. In addition, the first air supply cover 134 having the first air supply port 132 facing upward is connected to the first through hole 130, and the second air supply cover 144 having the second air supply port 142 facing downward is connected to the second through hole 140, so that the degree of freedom in the positions at which the first through hole 130 and the second through hole 140 are provided can be improved.

[0036] Moreover, exhaust air outlet 122 is a slit extending from first end 160 side to second end 162 side of air conditioner 150, and the slit is divided into multiple parts by multiple deflection plates 124, so that air is blown out from first end 160 side to second end 162 side, and the zoning area can be expanded. Moreover, exhaust air outlet 122 is a slit extending from first end 160 side to second end 162 side of air conditioner 150, and the slit is divided into multiple parts by multiple deflection plates 124, so that air is blown out from first end 160 side to second end 162 side, and the diffusion of air can be suppressed.
