DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, the embodiments (first embodiment, second embodiment) will be described with reference to Figs. 1 to 13. In this specification, the vertically upward direction is basically defined as the upward direction, and the vertically downward direction is basically defined as the downward direction. In addition, in this specification, the components according to the embodiment and the explanation of the components may be described using a plurality of expressions. The components and their explanations are merely examples, and are not limited by the expressions in this specification. The components may also be specified by names different from those in this specification. The components may also be described using expressions different from those in this specification.

[0014] (First embodiment) Fig. 1 is a cross-sectional view showing a schematic configuration of an indoor unit 11 of an air conditioner 10 of a first embodiment. As shown in Fig. 1, the air conditioner 10 has an indoor unit 11. The indoor unit 11 is placed inside a building, and is connected to an outdoor unit placed outside the building via refrigerant piping and electrical wiring. It should be noted that the air conditioner 10 is not limited to this example.

[0015] The indoor unit 11 has a housing 21, a heat exchanger 22, a fan 23, a filter 24, two airflow direction plates 25, and two ventilation members 26. The airflow direction plate 25 and the ventilation members 26 may also be referred to as louvers.

[0016] As shown in each drawing, for convenience, an X-axis, a Y-axis, and a Z-axis are defined in this specification. The X-axis, the Y-axis, and the Z-axis are perpendicular to each other. The X-axis is provided along the width of the indoor unit 11. The Y-axis is provided along the depth of the indoor unit 11. The Z-axis is provided along the height of the indoor unit 11.

[0017] Furthermore, in this specification, an X direction, a Y direction, and a Z direction are defined. The X direction is a direction along the X axis, and includes a +X direction indicated by an arrow on the X axis, and a -X direction opposite to the arrow on the X axis. The Y direction is a direction along the Y axis, and includes a +Y direction indicated by an arrow on the Y axis, and a -Y direction opposite to the arrow on the Y axis. The Z direction is a direction along the Z axis, and includes a +Z direction indicated by an arrow on the Z axis, and a -Z direction opposite to the arrow on the Z axis. In the first embodiment, the +Z direction is the upward direction, and the -Z direction is the downward direction.

[0018] The housing 21 is formed in a substantially rectangular parallelepiped shape extending in the X direction. The housing 21 may be formed in other shapes. The housing 21 is hung, for example, on a wall inside a building. The housing 21 has an upper surface 21a and a lower surface 21b. The upper surface 21a is provided at or near the upper end of the housing 21 and faces substantially upward. The lower surface 21b is provided at or near the lower end of the housing 21 and faces substantially downward.

[0019] The housing 21 is provided with an air passage 31, an inlet 32, and an outlet 33. The air passage 31 is provided inside the housing 21. The inlet 32 ​​opens, for example, to the upper surface 21a of the housing 21. The outlet 33 opens, for example, to the lower surface 21b of the housing 21. The inlet 32 ​​and the outlet 33 may open to other parts of the housing 21.

[0020] The indoor unit 11 can pass wind through the ventilation passage 31. Wind is a flow of air. The intake port 32 is provided at one end of the ventilation passage 31, and connects the ventilation passage 31 to the outside of the indoor unit 11. The outlet port 33 is provided at the other end of the ventilation passage 31, and connects the ventilation passage 31 to the outside of the indoor unit 11. In other words, the ventilation passage 31 is provided inside the housing 21, between the intake port 32 and the outlet port 33.

[0021] Heat exchanger 22 is provided in ventilation passage 31. Heat exchanger 22 has, for example, a refrigerant pipe and a plurality of fins. Heat exchanger 22 exchanges heat with the surrounding gas in ventilation passage 31. As a result, heat exchanger 22 cools the air flowing through ventilation passage 31 during cooling operation, and heats the air flowing through ventilation passage 31 during heating operation.

[0022] The fan 23 is an example of a blower that blows conditioned air into the room. The fan 23 is provided in the ventilation passage 31. The fan 23 rotates around a rotation axis Axf extending in the X direction to blow air from the intake port 32 to the exhaust port 33 in the ventilation passage 31. As a result, the indoor unit 11 draws indoor air from the intake port 32 into the ventilation passage 31 and blows out the air (wind) in the ventilation passage 31 from the exhaust port 33. For this reason, in this specification, the side of the ventilation passage 31 closer to the intake port 32 is referred to as the upstream side, and the side closer to the exhaust port 33 is referred to as the downstream side.

[0023] The fan 23 is located downstream of the heat exchanger 22. Therefore, when the fan 23 generates wind, the air sucked in from the intake port 32 passes through the fins of the heat exchanger 22. As a result, the air flowing through the ventilation passage 31 exchanges heat with the heat exchanger 22. As described above, the fan 23 can be switched between a "forward direction operation" in which the air (wind) flows from the intake port 32 to the exhaust port 33, and a "reverse direction operation" in which the air (wind) flows from the exhaust port 33 to the intake port 32. The forward direction operation is performed when the indoor unit 11 performs normal operation (including sterilization operation and non-sterilization operation). The reverse direction operation is performed, for example, when cleaning the inside of the indoor unit 11.

[0024] Filter 24 is provided at suction port 32 or near suction port 32 in ventilation passage 31. Filter 24 is located upstream of heat exchanger 22. Filter 24 covers suction port 32 from inside housing 21. Filter 24 filters, for example, air sucked in from suction port 32 and captures dust in the air.

[0025] 2 is a cross-sectional view showing a schematic configuration of the indoor unit 11 during operation according to the first embodiment. The two airflow direction vanes 25 are provided at the air outlet 33 or in the vicinity of the air outlet 33. The airflow direction vanes 25 are located downstream of the fan 23. The two airflow direction vanes 25 are arranged, for example, side by side in the approximate Y direction along the lower surface 21b.

[0026] Each of the two airflow direction vanes 25 can move between a first closed position Pc1 shown in Fig. 1 and a first open position Po1 shown in Fig. 2. The two airflow direction vanes 25 can move individually between the first closed position Pc1 and the first open position Po1.

[0027] 1, the airflow direction vane 25 located at the first closed position Pc1 covers a part of the air outlet 33. When both of the two airflow direction vanes 25 are located at the first closed position Pc1, the two airflow direction vanes 25 cover almost the entire area of ​​the air outlet 33.

[0028] 2, the airflow direction vane 25 located at the first opening position Po1 opens a portion of the air outlet 33. When both of the two airflow direction vanes 25 are located at the first opening position Po1, the two airflow direction vanes 25 open almost the entire area of ​​the air outlet 33.

[0029] The first open position Po1 includes various positions where the airflow direction vane 25 opens a part of the air outlet 33. For example, the first open position Po1 includes a position where the airflow direction vane 25 faces substantially horizontally, a position where the airflow direction vane 25 faces downward, and a plurality of positions between these two positions as shown in FIG. 2. That is, the airflow direction vane 25 can rotate between a position where the airflow direction vane 25 faces substantially horizontally and a position where the airflow direction vane 25 faces downward. The airflow direction vane 25 located at the first open position Po1 adjusts the vertical direction of the airflow discharged from the air outlet 33 depending on the direction of the airflow direction vane 25. That is, when the airflow direction vane 25 faces substantially horizontally as shown in FIG. 2, the indoor unit 11 discharges airflow in a substantially horizontal direction. On the other hand, when the airflow direction vane 25 faces downward, the indoor unit 11 discharges airflow downward.

[0030] The wind direction vanes 25 are made of, for example, synthetic resin. The wind direction vanes 25 may also be made of other materials such as metal. Each of the two wind direction vanes 25 has a shaft portion 41 and a plate portion 42.

[0031] The shaft portion 41 is formed in a substantially cylindrical shape extending in the X direction. The shaft portion 41 is supported by the housing 21 so as to be rotatable about a rotation axis Axl extending in the X direction. Each of the multiple airflow direction vanes 25 has its own individual rotation axis Axl. The plate portion 42 protrudes from the shaft portion 41 in a direction substantially perpendicular to the rotation axis Axl. The plate portion 42 is formed in a substantially rectangular plate shape extending in the X direction. By rotating the shaft portion 41 about the rotation axis Axl, the airflow direction vane 25 can move between a first closed position Pc1 and a first open position Po1.

[0032] In the following description, the two wind direction vanes 25 may be individually referred to as wind direction vanes 25A and 25B. In other words, the two wind direction vanes 25 include wind direction vane 25A and wind direction vane 25B. Note that a description common to wind direction vanes 25A and 25B will be described as a description of wind direction vane 25.

[0033] The airflow direction vane 25A is located between the upper end 33a of the air outlet 33 and the lower end 33b of the air outlet 33 in the Z direction. The airflow direction vane 25B is located near the lower end 33b of the air outlet 33. The airflow direction vane 25A is closer to the upper end 33a of the air outlet 33 than the airflow direction vane 25B. The airflow direction vane 25B is closer to the lower end 33b of the air outlet 33 than the airflow direction vane 25A.

[0034] The airflow direction vanes 25A and 25B located at the first open position Po1 divide the air outlet 33 into two flow paths C1 and C2. The flow path C1 is a part of the air outlet 33 and is located between the airflow direction vane 25A and the upper end 33a of the air outlet 33. The flow path C2 is a part of the air outlet 33 and is located between the airflow direction vane 25A and the lower end 33b of the air outlet 33. In other words, the flow path C2 is located between the airflow direction vane 25A and the airflow direction vane 25B.

[0035] The airflow direction vane 25A opens the flow path C1 in the first open position Po1 and covers the flow path C1 in the first closed position Pc1. The airflow direction vane 25B opens the flow path C2 in the first open position Po1 and covers the flow path C2 in the first closed position Pc1.

[0036] The two ventilation members 26 are provided at or near the air outlet 33. The ventilation members 26 are located downstream of the fan 23. The two ventilation members 26 are disposed, for example, substantially side by side in the Y direction.

[0037] Each of the two ventilation members 26 can move between a second closed position Pc2 shown by a solid line in Fig. 2 and a second open position Po2 shown by a two-dot chain line in Fig. 2. In other words, the ventilation members 26 can be disposed at the second closed position Pc2. The two ventilation members 26 can move individually between the second closed position Pc2 and the second open position Po2.

[0038] In the following description, the two ventilation members 26 may be individually referred to as ventilation members 26A and 26B. In other words, the two ventilation members 26 include ventilation members 26A and 26B. Note that a description common to the ventilation members 26A and 26B will be described as a description of the ventilation member 26.

[0039] For example, ventilation member 26A is located near the upper end 33a of outlet 33. Ventilation member 26B is located between the upper end 33a of outlet 33 and the lower end 33b of outlet 33 in the Z direction. Ventilation member 26A is closer to the upper end 33a of outlet 33 than ventilation member 26B. Ventilation member 26B is closer to the lower end 33b of outlet 33 than ventilation member 26A. Note that the positions of ventilation members 26A and 26B are not limited to this example.

[0040] The ventilation member 26 located at the second closed position Pc2 covers a part of the outlet 33 opened by the air deflector 25 located at the first open position Po1. In the first embodiment, the ventilation member 26A located at the second closed position Pc2 covers the flow path C1 opened by the air deflector 25A located at the first open position Po1. Furthermore, the ventilation member 26B located at the second closed position Pc2 covers the flow path C2 opened by the air deflector 25B located at the first open position Po1.

[0041] When both of the two ventilation members 26 are located at the second closed position Pc2, the two ventilation members 26 cover all of the flow paths C1, C2. The two ventilation members 26 located at the second closed position Pc2 do not need to completely block the air outlet 33. For example, the air outlet 33 may be connected to the room without being covered by the ventilation members 26 in the X direction, or the air may pass through the gap between the ventilation members 26 and the air direction plate 25. In the first embodiment, it is sufficient that most of the flow paths C1, C2 are covered by the ventilation members 26A, 26B when viewed in the air travel direction. The manner in which the ventilation members 26 cover the air outlet 33 is not limited to this example.

[0042] The ventilation member 26 positioned at the second open position Po2 opens a part of the outlet 33 opened by the air deflector 25 positioned at the first open position Po1. In the first embodiment, the ventilation member 26A positioned at the second open position Po2 opens the flow path C1 opened by the air deflector 25A positioned at the first open position Po1. Furthermore, the ventilation member 26B positioned at the second open position Po2 opens the flow path C2 opened by the air deflector 25B positioned at the first open position Po1.

[0043] The ventilation members 26 are made of, for example, synthetic resin. The ventilation members 26 may also be made of other materials such as metal. Each of the two ventilation members 26 has a shaft portion 51 and a plate portion 52.

[0044] The shaft portion 51 is formed in a substantially cylindrical shape extending in the X direction. The shaft portion 51 is supported by the housing 21 so as to be rotatable about a rotation axis Axc extending in the X direction. Each of the multiple ventilation members 26 has its own rotation axis Axc. The plate portion 52 protrudes from the shaft portion 51 in a direction substantially perpendicular to the rotation axis Axc. The plate portion 52 is formed in a substantially rectangular plate shape extending in the X direction. By rotating the shaft portion 51 about the rotation axis Axc, the ventilation member 26 can move between the second closed position Pc2 and the second open position Po2.

[0045] The shaft portion 51 of the ventilation member 26 is spaced upward from the plate portion 42 of the airflow direction flap 25 located in the first open position Po1. The plate portion 52 of the ventilation member 26 located in the second closed position Pc2 extends from the shaft portion 51 toward the plate portion 42 of the airflow direction flap 25.

[0046] The tip 52a of the plate portion 52 of the ventilation member 26 located in the second closed position Pc2 abuts against the plate portion 42 of the airflow direction flap 25 or is located near the plate portion 42. As a result, the ventilation member 26 located in the second closed position Pc2 covers a part of the outlet 33 opened by the airflow direction flap 25 located in the first open position Po1. The tip 52a is an end of the plate portion 52 located on the opposite side to the shaft portion 51.

[0047] The length of the plate portion 52 in the X direction is approximately equal to the length of the outlet 33 in the X direction. This allows the ventilation members 26A, 26B located in the second closing position Pc2 to cover most of the flow paths C1, C2.

[0048] The length of the plate portion 52 in the direction in which the plate portion 52 protrudes from the shaft portion 51 is shorter than the maximum length of each of the flow paths C1 and C2 in the Z direction. This prevents the ventilation member 26 from interfering with the airflow direction plate 25 when moving between the second closed position Pc2 and the second open position Po2.

[0049] The plate portion 52 has an inner surface 52b and an outer surface 52c. The inner surface 52b faces the ventilation passage 31 in the second closed position Pc2. The outer surface 52c is located on the opposite side to the inner surface 52b. The outer surface 52c faces the outside of the indoor unit 11 in the second closed position Pc2.

[0050] When both of the two ventilation members 26 are located at the second open position Po2, the two ventilation members 26 open almost the entire area of ​​the outlet 33 opened by the air deflector 25 located at the first open position Po1. Note that even if the two ventilation members 26 are located at the second open position Po2, when the air deflector 25 is located at the first closed position Pc1, the flow paths C1, C2 are covered by the corresponding air deflector 25.

[0051] 1, ventilation member 26A located at second open position Po2 is accommodated in recess 21c of housing 21 provided near air outlet 33. Recess 21c is recessed from inner surface 21d of housing 21 forming part of ventilation passage 31. By being accommodated in recess 21c, ventilation member 26A located at second open position Po2 is prevented from obstructing the wind flowing through ventilation passage 31.

[0052] The ventilation member 26B is provided in the ventilation passage 31 near the air outlet 33. The plate portion 52 of the ventilation member 26B located in the second open position Po2 extends in a direction along the flow of air in the ventilation passage 31. This prevents the ventilation member 26B located in the second open position Po2 from obstructing the air flowing through the ventilation passage 31. Note that the arrangement of the ventilation members 26A, 26B located in the second open position Po2 is not limited to the above example.

[0053] Although illustrations and detailed explanations are omitted, the indoor unit 11 further has left and right air deflectors that adjust the left-right direction of the air discharged from the air outlet 33. The left and right air deflectors are provided, for example, in the ventilation passage 31. The indoor unit 11 can discharge air in the direction in which the left and right air deflectors face. The air deflector 25 and the left and right air deflectors are examples of air direction adjustment parts that adjust the direction of the air coming out of the fan 23. Hereinafter, the air deflector 25 and the left and right air deflectors may be collectively referred to as "air deflectors".

[0054] Fig. 3 is a front view showing a schematic view of the airflow direction plate 25 and a part of the ventilation member 26 of the first embodiment. Fig. 4 is a cross-sectional view showing a schematic view of the configuration of the ventilation member 26 of the first embodiment. As shown in Fig. 3, each of the ventilation members 26 is provided with a plurality of first ventilation holes 55 and a plurality of second ventilation holes 56. Each of the ventilation members 26 may be provided with one first ventilation hole 55 and one second ventilation hole 56.

[0055] 4, the multiple first ventilation holes 55 and the multiple second ventilation holes 56 are through holes penetrating the plate portion 52. Therefore, the multiple first ventilation holes 55 and the multiple second ventilation holes 56 open to the inner surface 52b and the outer surface 52c of the plate portion 52, respectively.

[0056] The multiple first ventilation openings 55 and the multiple second ventilation openings 56 are alternately arranged in the arrangement direction Dp. Therefore, the first ventilation openings 55 and the second ventilation openings 56 are provided side by side in the arrangement direction Dp. The arrangement direction Dp is a direction along the outer surface 52c of the plate portion 52.

[0057] In the first embodiment, the arrangement direction Dp is approximately equal to the direction in which the plate portion 52 extends from the shaft portion 51. When the ventilation member 26 is located in the second closed position Pc2, the arrangement direction Dp is approximately equal to the Z direction. Note that the arrangement direction Dp is not limited to this example and may be another direction such as the X direction.

[0058] 3, the first ventilation opening 55 is, for example, a substantially rectangular slit extending in the X direction. The X direction is a direction that runs along the outer surface 52c of the plate portion 52 and intersects with the arrangement direction Dp. The first ventilation opening 55 may be a hole having a cross section that is circular, rectangular, triangular, or of another shape. The multiple first ventilation openings 55 are arranged in the arrangement direction Dp.

[0059] The second ventilation hole 56 is a hole having a circular cross section. The second ventilation hole 56 may be a hole having a rectangular, triangular, or other shaped cross section. In the first embodiment, the cross sections of the first ventilation hole 55 and the second ventilation hole 56 are cross sections perpendicular to the direction in which the first ventilation hole 55 and the second ventilation hole 56 penetrate the plate portion 52.

[0060] The second ventilation openings 56 are arranged in the X direction. In other words, the second ventilation openings 56 are arranged at intervals from one another in the X direction. Therefore, the second ventilation openings 56 form rows 58 of the second ventilation openings 56 arranged in the X direction. In the plate portion 52, the rows 58 are arranged in the arrangement direction Dp. The second ventilation openings 56 may be arranged in a lattice pattern or a staggered pattern.

[0061] In the first embodiment, a plurality of slit-shaped first ventilation holes 55 and a row 58 of second ventilation holes 56 are alternately arranged in the arrangement direction Dp. Therefore, the plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 form a row 59 of the first ventilation holes 55 and the second ventilation holes 56 aligned in the arrangement direction Dp.

[0062] The first ventilation openings 55 are arranged at both ends of a row 59 of the first ventilation openings 55 and the second ventilation openings 56 aligned in the arrangement direction Dp. Therefore, in the arrangement direction Dp, the second ventilation openings 56 are located between two of the first ventilation openings 55. Note that in the ventilation member 26 of the first modified example of the first embodiment, the second ventilation opening 56 may be arranged at an end of the row 59 of the first ventilation openings 55 and the second ventilation openings 56 aligned in the arrangement direction Dp. In this case, the first ventilation openings 55 are located between two of the second ventilation openings 56 in the arrangement direction Dp.

[0063] 3, the cross section of each of the second vents 56 is smaller than the cross section of each of the first vents 55. In addition, the sum of the cross sections of the second vents 56 included in each of the rows 58 is smaller than the cross section of one of the first vents 55.

[0064] 4, each of the multiple first ventilation openings 55 has an enlarged portion 61 and a straight portion 62. The enlarged portion 61 and the straight portion 62 are each a part of the first ventilation opening 55. The enlarged portion 61 and the straight portion 62 are continuous in the thickness direction from the inner surface 52b of the plate portion 52 to the outer surface 52c.

[0065] The enlarged portion 61 is a portion that opens to the outer surface 52c of the plate portion 52, and has a cross section that expands as it approaches the outer surface 52c. In other words, the enlarged portion 61 is a portion that has a cross section that contracts as it moves from the outer surface 52c toward the inner surface 52b. Moreover, the enlarged portion 61 approaches the adjacent second ventilation opening 56 as it approaches the outer surface 52c.

[0066] The straight portion 62 opens to the inner surface 52b and is connected to the enlarged portion 61. The straight portion 62 is a portion having a constant cross-sectional size between the inner surface 52b and the enlarged portion 61. The cross-sectional size of the straight portion 62 is approximately equal to the cross-sectional size of the enlarged portion 61 at its smallest portion.

[0067] The diameter of the maximum portion of the expanded portion 61 is set to, for example, 3 to 5 mm. Furthermore, the diameters of the minimum portion and the straight portion 62 of the expanded portion 61 are set to, for example, 50 to 90% of the diameter of the maximum portion of the expanded portion 61. The size of the first ventilation opening 55 is not limited to this example.

[0068] Each of the multiple second ventilation openings 56 also has an enlarged portion 65 and a straight portion 66. The enlarged portion 65 and the straight portion 66 are each a part of the second ventilation opening 56. The enlarged portion 65 and the straight portion 66 are continuous in the thickness direction from the inner surface 52b of the plate portion 52 to the outer surface 52c.

[0069] The enlarged portion 65 is a portion that opens to the outer surface 52c of the plate portion 52, and has a cross section that expands as it approaches the outer surface 52c. In other words, the enlarged portion 65 has a cross section that contracts as it moves from the outer surface 52c toward the inner surface 52b. Moreover, the enlarged portion 65 approaches the adjacent first ventilation opening 55 as it approaches the outer surface 52c.

[0070] The straight portion 66 opens to the inner surface 52b and is connected to the enlarged portion 65. The straight portion 66 is a portion having a constant cross-sectional size between the inner surface 52b and the enlarged portion 65. The cross-sectional size of the straight portion 66 is approximately equal to the cross-sectional size of the enlarged portion 65 at its smallest portion.

[0071] In another modified example of the first embodiment, the first ventilation opening 55 may have a reduced portion instead of the straight portion 62. The reduced portion opens to the inner surface 52b of the plate portion 52 and is connected to the expanded portion 61. The reduced portion is a portion whose cross section reduces as it approaches the expanded portion 61. Also, the second ventilation opening 56 may have a reduced portion instead of the straight portion 62. The reduced portion opens to the inner surface 52b of the plate portion 52 and is connected to the expanded portion 65. The reduced portion is a portion whose cross section reduces as it approaches the expanded portion 65.

[0072] The first ventilation opening 55 and the second ventilation opening 56 are not limited to these examples. For example, the first ventilation opening 55 may have one of an enlarged portion 61, a straight portion 62, and a reduced portion. Similarly, the second ventilation opening 56 may have one of an enlarged portion 65, a straight portion 66, and a reduced portion.

[0073] Fig. 5 is a block diagram showing the functional configuration of the indoor unit 11 of the air conditioner 10 of the first embodiment. As shown in Fig. 5, the indoor unit 11 has a control device 80 (control unit), a first drive circuit 81, a second drive circuit 82, a third drive circuit 83, a fan motor 84, two wind direction vane motors 85, 86, two switching motors 87, 88, a notification unit 90, a Doppler radar 91 (an example of a radar), and a receiving device 94. Although not shown in the figures or detailed description, the indoor unit 11 also has drive circuits and wind direction vane motors corresponding to the left and right wind direction vanes. The indoor unit 11 may have other configurations.

[0074] The control device 80, first drive circuit 81, second drive circuit 82, third drive circuit 83, fan motor 84, wind direction vane motors 85, 86, switching motors 87, 88, alarm unit 90, Doppler radar 91, and receiving device 94 are housed in the housing 21.

[0075] The control device 80 includes, for example, a processor such as a CPU (Central Processing Unit) and a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a flash memory. Note that the control device 80 is not limited to this example.

[0076] The processor reads and executes a program from the storage device, whereby the control device 80 controls the operation of the air conditioning device 10. The control device 80 is connected to, for example, a first drive circuit 81, a second drive circuit 82, a third drive circuit 83, an alarm unit 90, and a receiving device 94. The control device 80 also receives detection results from various sensors such as a Doppler radar 91.

[0077] The first drive circuit 81 is a drive circuit for the fan motor 84. The fan motor 84 drives the fan 23 to rotate around the rotation axis Axf. The control device 80 controls the first drive circuit 81 to execute forward rotation control (control for discharging wind from the air outlet 33) or reverse rotation control of the fan motor 84 and the fan 23.

[0078] The second drive circuit 82 is a drive circuit for two vane motors 85, 86. The vane motors 85, 86 each drive the corresponding vane 25 to rotate about the rotation axis Axl. In the first embodiment, the vane motor 85 drives the vane 25A to rotate about the rotation axis Axl of the vane 25A. The vane motor 86 drives the vane 25B to rotate about the rotation axis Axl of the vane 25B. The control device 80 controls the second drive circuit 82 to control the vane motors 85, 86 and the vanes 25A, 25B.

[0079] The third drive circuit 83 is a drive circuit for two switching motors 87, 88. The switching motors 87, 88 each drive the corresponding ventilation member 26 to rotate about the rotation axis Axc. In the first embodiment, the switching motor 87 drives the ventilation member 26A to rotate about the rotation axis Axc of the ventilation member 26A. The switching motor 88 drives the ventilation member 26B to rotate about the rotation axis Axc of the ventilation member 26B. The control device 80 controls the third drive circuit 83 to control the switching motors 87, 88 and the ventilation members 26A, 26B.

[0080] Furthermore, detection results from various sensors are sequentially input to the control device 80, and the control device 80 reflects the input detection results in each control.

[0081] The Doppler radar 91 emits electromagnetic waves (light, etc.), ultrasonic waves, etc., and detects the reflected waves that are reflected by an object (living body, etc.). The Doppler radar 91 in the first embodiment is provided on the surface of the housing 21 of the indoor unit 11 at a position facing the room, and detects the position (direction, distance, etc. from the air conditioning device 10) of a living body present in the room where the indoor unit 11 is installed and characteristics related to the living body. In detail, the Doppler radar 91 detects information related to the position of the living body present in the room and the characteristics of the living body, and the control device 80 determines the characteristics of the living body based on this information. The control device 80 determines, for example, the type and posture of each living body present in the room as characteristics related to the living body. The control device 80 in the first embodiment determines, as the type of living body, which of the following types based on the size of the living body, for example, an adult, a child, or a non-human animal (for example, a pet such as a dog or a cat). In the first embodiment, "adult" refers to an adult human, and "child" refers to a child human.

[0082] More specifically, the Doppler radar 91 in the first embodiment is, for example, a millimeter wave radar with a frequency of about 30G to 300GHz. The Doppler radar 91 can recognize (detect) the size of an object, the distance to the object, the angle, the speed, and the like. For example, when the Doppler radar 91 recognizes a living body, it can distinguish between an adult, a child, and a pet in ascending order according to the height of the living body. In this case, for example, if it is 110 cm or less, it may be distinguished as a child, and if it is about 50 cm, it may be distinguished as an animal, but this is not limited to this. For example, the size and shape of a specific part of the living body (for example, the head), and other movements of the living body may be detected to distinguish between an adult, a child, a pet, and the like. Note that whether or not an object is a living body can be determined, for example, by whether or not the object detected by the Doppler radar 91 moves. In addition, for example, various sensors such as an infrared sensor may be used to detect the temperature, movement, amount of activity, and sounds emitted from the living body to determine whether or not it is a living body.

[0083] The Doppler radar 91 detects at least whether the living body is lying down as the posture of the living body. For example, the Doppler radar 91 may detect whether the living body is standing, lying down, crouching, etc., but is not limited to this. These postures can be determined, for example, by detecting the height or shape of the living body, or changes therein. The Doppler radar 91 may also detect, for example, the amount of movement of the living body as a feature related to the living body. The Doppler radar 91 transmits the detection result to the control device 80.

[0084] The notification unit 90 notifies various indoor conditions by lamps and sounds.

[0085] The receiving device 94 receives, for example, a wireless signal in the form of an electromagnetic wave such as infrared rays from a remote controller 94a (remote control). The receiving device 94 transmits an instruction signal from the remote controller 94a to the control device 80.

[0086] The remote controller 94a is a device used for user operations on the air conditioning apparatus 10. A user can also perform operations on the air conditioning apparatus 10 (operations for making reservations, operations for issuing real-time operation instructions, etc.) using a mobile terminal (e.g., a smartphone, etc.) on which a dedicated app (application program) is installed. Below, the remote controller 94a will be described using Fig. 6, and the mobile terminal will be described using Fig. 7.

[0087] 6 is a diagram showing a schematic external view of the remote controller 94a in the first embodiment. Area B1 is a display screen that displays the operation mode (cooling, etc.), the current room temperature, the air volume, the remaining battery level of the remote controller 94a, power select switching, etc.

[0088] Area B2 has the following buttons arranged. First, there are a cooling button, a heating button, a dehumidification button, an air purification (cleaning) button, an automatic (control to bring the room temperature closer to the set temperature) button, and a windless (registered trademark) button for specifying the operation mode. Note that the air purification operation includes various methods, and is not limited to an operation to remove dust and the like from the air, but also includes an operation to release ions and the like into the air. Also, the windless mode is a mode that realizes a gentle airflow using the ventilation member 26, and is used in combination with other modes (for example, cooling + windless).

[0089] In addition, a stop button for stopping operation, a temperature setting button, and a position setting button B are arranged. When the position setting button B is pressed, the Doppler radar 91 detects the position of the remote controller 94a, and the control device 80 sets (stores) that position as a target position. The target position is specified, for example, by the direction and distance from the indoor unit 11 (or the Doppler radar 91). The target position may be specified in a two-dimensional space (i.e., a plane) or in a three-dimensional space including the height direction.

[0090] Specifically, for example, the Doppler radar 91 detects a person operating the remote controller 94a, and the control device 80 sets the position of the person as the target position. Note that the position of the remote controller 94a may be detected directly and set as the target position. An automatic wind direction button and an automatic wind shield button are arranged in the area B2 of the remote controller 94a. When the user presses the automatic wind direction button, automatic wind direction control for the target position (wind direction control for controlling the wind direction in a direction that avoids the target position) is executed, and when the user presses the automatic wind shield button, automatic wind direction control for the target position (wind direction control for controlling the wind direction in a direction that avoids the target position) is executed.

[0091] The control device 80 may also be configured to set a plurality of positions as target positions. In this case, for example, automatic wind blowing control or automatic wind shielding control can be set for each target position, such as automatic wind blowing control for target position 1 and automatic wind shielding control for target position 2. Also, for example, information indicating the location of each target position, such as "target position 1 is a sofa" or "target position 1 is an aisle," may be input and displayed on a mobile terminal.

[0092] In area B3, various buttons are arranged on the back of the cover.

[0093] 7 is a diagram showing a schematic diagram of a smartphone screen in the first embodiment. A display area A1 displays a "weekly timer," which is a weekly timer function of the air conditioning apparatus .

[0094] Display area A2 displays Sunday through Saturday, with the currently selected day of the week (Tuesday in this example) displayed darker.

[0095] Display area A3 displays the time for the scheduled operation to be "on" or "off" for the day of the week selected in display area A2. In the 24-hour display, the dark time periods are the time periods during which scheduled operation will take place.

[0096] The display area A4 accepts input of operation schedules. There are five operation modes here: cooling, heating, dehumidification, air purification, and automatic. It also has displays for setting the temperature and air volume.

[0097] The display area A6 accepts the addition of a No Wind Feeling (registered trademark) operation to the operation selected in the display area A4. The No Wind Feeling is an operation mode in which the ventilation member 26 is used to realize a gentle wind flow.

[0098] The display area A5 accepts input of the wind direction setting. There are three wind direction settings: manual wind direction setting, automatic wind direction, and automatic wind shield. When the manual wind direction setting is selected, a screen is displayed in which the user can set the wind direction (up and down wind direction and left and right wind direction).

[0099] When automatic airflow control is selected, automatic airflow control for the target position is set. In addition, when multiple target positions are set, for example, after automatic airflow control is selected, one or more target positions for which automatic airflow control is to be performed are selected from the multiple target positions set. In automatic airflow control, the airflow direction plates (airflow direction plates 25A, 25B and left and right airflow direction plates) are controlled and adjusted so that the airflow direction faces one or more target positions. In addition, the airflow direction means the direction of the wind. In this specification, the direction in which the airflow direction plate faces is controlled, but the direction in which the airflow direction plate faces and the direction of the wind (wind direction) immediately after being blown out from the air outlet 33 generally coincide with each other. In other words, the airflow direction plate can adjust the airflow direction by its direction, and the control device 80 can control the airflow direction by controlling the direction of the airflow direction plate. In addition, the direction of the multiple left and right airflow direction plates in the first embodiment can be controlled individually. This allows wind with a uniform wind direction to be blown out from the entire air outlet 33, and allows two or more winds with different wind directions to be blown out from two or more areas of the air outlet 33 partitioned by a plurality of air direction plates.

[0100] Here, Fig. 8 is an explanatory diagram of an example of automatic wind blowing control in the first embodiment. Fig. 8 shows a schematic view of the interior of a room as viewed from above (similar to Fig. 9). Fig. 8(a) shows a case where automatic wind blowing control is not performed. In this case, wind is not blown to the target position A.

[0101] On the other hand, Fig. 8(b) shows a case where automatic wind direction control is performed. In this case, the wind can be directed toward target position A by controlling the wind direction vane. That is, the position of target A is detected by Doppler radar 91, and the wind direction vane is controlled so that the wind is directed toward target A. Note that Fig. 8 shows automatic wind direction control in the horizontal direction, but automatic wind direction control in the vertical direction can also be performed in the same way (similar to Fig. 9).

[0102] Returning to Fig. 7, when the automatic wind shield is selected, automatic wind shield control for the target position is set. If multiple target positions are set, for example, after selecting the automatic wind shield, one or more target positions for which automatic wind shield control is to be performed are selected from the multiple target positions that have been set. In the automatic wind shield control, the wind direction vanes (wind direction vanes 25A, 25B and left and right wind direction vanes) are controlled, and the wind direction is adjusted to avoid the selected target.

[0103] 9A and 9B are explanatory diagrams of an example of automatic windshield control in the first embodiment. Fig. 9A shows a case where automatic windshield control is not performed. In this case, wind is sent to the target position B.

[0104] 9(b) shows a case where automatic wind shield control is performed. In this case, the wind direction vane is controlled to prevent wind from being blown toward target position B. That is, the position of target B is detected by Doppler radar 91, and the wind direction vane is controlled so that the wind is directed in a direction that avoids target B.

[0105] Returning to FIG. 5, the control device 80 functions as a timer setting unit that performs timer setting including wind direction setting to set wind blowing control or wind shield control for a target position during scheduled operation based on a user operation (selection between automatic wind blowing control and automatic wind shield control).

[0106] 10 is a flowchart showing an example of control by the air conditioning apparatus 10 of the first embodiment. In step S1, the Doppler radar 91 determines whether or not the position setting button B has been pressed on the remote controller 94a, and if Yes, the process proceeds to step S2, and if No, the process returns to step S1.

[0107] In step S2, the control device 80 receives information on the position of the person operating the remote controller 94a from the Doppler radar 91, and sets the position of that person as the target position.

[0108] Next, in step S3, the control device 80 accepts a driving reservation via the mobile terminal (FIG. 7).

[0109] Next, in step S4, the control device 80 accepts a wind direction setting for a target position via the mobile terminal (FIG. 7). Here, it is assumed that the user has set automatic wind blowing control or automatic wind shield control for the target position.

[0110] Next, in step S5, the control device 80 controls the wind direction adjustment (executes automatic wind blowing control or automatic wind shield control for a target position) in a predetermined operation mode (e.g., cooling, heating, etc.) based on the timer settings (reserved operation settings and wind direction settings) during the reserved operation (FIGS. 8 and 9).

[0111] In this way, according to the air conditioning device 10 of the first embodiment, the position of the remote controller 94a when the position setting button B is pressed on the remote controller 94a is set as the target position based on the detection results by the Doppler radar 91, and during air conditioning operation in a specified mode, automatic wind blowing control or automatic wind shielding control is executed for the target position based on the setting by the user operation. This makes it possible to easily achieve the wind direction desired by the user.

[0112] Furthermore, compared to performing automatic wind control or automatic wind shield control on a living body (person, pet, etc.) detected in real time by the Doppler radar 91, automatic wind control or automatic wind shield control only needs to be performed on a set target position, which reduces the amount of processing required by the Doppler radar 91 and the control device 80.

[0113] In addition, by executing automatic air blowing control or automatic air shielding control for a target position during air conditioning operation using the timer function, suitable control can be achieved that takes into account the date and time and temperature and humidity conditions.

[0114] Second embodiment Next, a second embodiment will be described. Descriptions of matters similar to those in the first embodiment will be omitted as appropriate. Figures 11 to 13 are illustrative and schematic diagrams showing the structure of an air conditioning device 10 (indoor unit 11) according to a second embodiment.

[0115] The configuration of the air conditioner 10 (indoor unit 11) shown in Fig. 11 is basically the same as the configuration of the first embodiment shown in Fig. 2, but differs in the shape of the ventilation member 26 and in that the ventilation member 26 is arranged only on the flow path C1 side of the two flow paths C1, C2. Therefore, in the configurations of Fig. 2 and Fig. 11, components that are substantially the same are given the same reference numerals and detailed descriptions thereof will be omitted.

[0116] The ventilation member 26 arranged in the flow path C1 of the air conditioner 10 (indoor unit 11) in the second embodiment is a component in which only a plurality of second ventilation openings 56 are arranged, as shown in FIG. 12. The ventilation member 26 in which only the second ventilation openings 56 are arranged is referred to as the ventilation member 26C. In other words, the ventilation member 26C does not have the first ventilation opening 55 that exists in the ventilation member 26A and the ventilation member 26B. The ventilation member 26C is supported by the shaft portion 51, like the ventilation member 26A and the ventilation member 26B, and the switching motor is controlled by the third drive circuit 83, and can be moved between the second closed position Pc2 and the second open position Po2. Then, when the ventilation member 26C is moved to the second closed position Pc2, as shown in FIG. 13, the wind moving in the ventilation passage 31 by the fan 23 passes through the second ventilation openings 56 and changes to the second wind W2a. Therefore, the first air W1 (laminar flow) is not generated in the ventilation member 26C.

[0117] On the other hand, the ventilation member 26C is not provided in the outlet 33 forming the flow path C2. That is, the wind discharged from the flow path C2 becomes the first wind W1a (laminar flow) that does not pass through the ventilation member 26C (second ventilation port 56). As a result, the wind (second wind W2a) passing through the ventilation member 26C (second ventilation port 56) provided in the flow path C1 and the wind (first wind W1a) passing through the flow path C2 where the ventilation member 26C (second ventilation port 56) is not provided are formed adjacent to each other. In this case, as described in the ventilation member 26A (ventilation member 26B) shown in the first embodiment, the second wind W2a draws in the first wind W1a because of its high flow speed. As a result, the first wind W1a hits the second wind W2a. Moreover, the second wind W2a that has transitioned to a turbulent flow diffuses and hits the first wind W1a flowing adjacent to the second wind W2a. In this way, the first wind W1a and the second wind W2a, which have different flow speeds and states (laminar flow or turbulent flow), flow next to each other and hit each other. That is, the first wind W1a that does not pass through the ventilation member 26C (second ventilation port 56) and the second wind W2a that has passed through the ventilation member 26C (second ventilation port 56) interfere with each other.

[0118] When the first wind W1a and the second wind W2a hit each other, for example, the masses of the first wind W1a and the second wind W2a are broken, and the second wind W2a, which is a turbulent flow, is carried by the first wind W1a. The first wind W1a and the second wind W2a generate such various interactions to generate a turbulent flow Ws that diffuses over a wide area. As a result, the turbulent flow Ws discharged from the air conditioner 10 (indoor unit 11) in the second embodiment is closer to a natural wind (so-called wind without a windy feeling) than the wind immediately after being discharged from the air outlet 33, as in the air conditioner 10 (indoor unit 11) in the first embodiment. In this case, the ventilation member 26C only needs to be formed in one of the two flow paths C1 and C2, which can contribute to reducing the number of parts, simplifying the configuration of the air conditioner 10 (indoor unit 11), and reducing costs. Moreover, ventilation member 26C has a simple structure including only second ventilation port 56, which can contribute to reducing costs and improving the strength of ventilation member 26C.

[0119] By using such an air conditioner 10 as shown in Figs. 11 to 13, the air direction desired by the user can be easily achieved, as in the case of the first embodiment.

[0120] In the air conditioner 10 according to the first and second embodiments described above, the ventilation member 26 can be arranged in the second closed position Pc2, which covers at least a part of the outlet 33 opened by the air direction plate 25 located in the first open position Po1. In the second closed position Pc2, a first outlet flow path in which the wind sent by the fan 23 passes through the second ventilation port 56 and is discharged to the outside, and a second outlet flow path in which the wind is discharged to the outside adjacent to the first outlet flow path without passing through the second ventilation port 56, can be formed. As described above, the flow speeds of the wind passing through the second ventilation port 56 and the wind not passing through the second ventilation port 56 are different from each other. Since the winds with different flow speeds are arranged side by side, the first wind and the second wind collide with each other outside the air conditioner 10 due to various factors such as the flow speed difference and the difference in the ease of transition to turbulence, generating a turbulent flow Ws that diffuses over a wide area. The turbulent flow Ws is closer to natural wind (wind that feels like no wind) than wind discharged from the outlet 33 without passing through the second ventilation opening 56. Therefore, the air conditioning device 10 of the present embodiment makes the wind that hits the user closer to natural wind, making it possible to reduce the discomfort of the user.

[0121] Although the embodiment of the present invention has been described above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. The above embodiment is included in the scope and gist of the invention, and is included in the scope of the invention and its equivalents described in the claims.

[0122] For example, when automatic air blowing control is performed, the notification unit 90 may output a voice such as "A person has been detected" or "Air will be blown on the person."

[0123] In addition, if there are multiple people in the room and the Doppler radar 91 cannot identify the person operating the remote controller 94a when the position setting button B of the remote controller 94a is pressed, the notification unit 90 may be configured to issue an error message stating "Multiple people present, position cannot be set."

[0124] Furthermore, when the user presses the position setting button B of the remote controller 94a in one of the four corners of the room, the control device 80 may recognize the shape and size of the room, and the recognized information may be used when determining the airflow volume, etc.

[0125] In addition, when automatic airflow control is being performed, the automatic airflow control may be released (ended) if the Doppler radar 91 detects that no living body is in the room, if a predetermined time (e.g., 30 minutes) has passed since the start of control, if a predetermined time has arrived, or if the room temperature drops to a predetermined temperature in the case of cooling.

[0126] In addition, the wind direction setting may be set to at least one of automatic wind direction or automatic wind shield. For example, only automatic wind direction may be displayed in the display area A5, and only automatic wind direction control may be set as the wind direction setting. Alternatively, only automatic wind shield may be displayed in the display area A5, and only automatic wind shield control may be set as the wind direction setting.

[0127] Furthermore, a windless operation may be used as the automatic windbreak control. In this case, the windless operation may be executed instead of the wind vane control in which the wind direction is turned in a direction to avoid the target, or the windless operation may be executed in combination with the wind vane control in which the wind direction is turned in a direction to avoid the target.

[0128] Furthermore, the time span of the operation reservation is not limited to a week, but may be another unit such as a month, a season, or a year.

[0129] In addition, the reservation operation settings for the air conditioning apparatus 10 may be stored in a storage device within the air conditioning apparatus 10, or may be stored in an external storage device such as a server with which communication is performed when operations related to the air conditioning apparatus 10 are performed on a mobile terminal.

[0130] In addition to the Doppler radar 91, another living body detection sensor (for example, a sensor that detects infrared rays emitted from a living body) may be used in combination.

[0131] In addition, in the above-mentioned first and second embodiments, the description was given assuming, for example, a residential air conditioner 10, but the configuration of this embodiment can be similarly applied to various air conditioners. For example, the configuration of this embodiment can be applied to commercial air conditioners and air conditioners installed in vehicles, aircraft, ships, etc., and similar effects can be obtained.
