(First embodiment)
A first embodiment will be described below with reference to FIGS. 1 to 7. Note that, 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. Further, in this specification, a component according to an embodiment and a description of the component may be described in multiple expressions. The components and their descriptions are examples and are not limited by the language in this specification. Components may also be identified by different names than herein. Also, components may be described using language that differs from that used herein.

FIG. 1 is a sectional view schematically showing an indoor unit 11 of an air conditioner 10 according to the first embodiment. As shown in FIG. 1, the air conditioner 10 includes an indoor unit 11. The indoor unit 11 is placed indoors in a building, and is connected to an outdoor unit placed outdoors via refrigerant piping and electrical wiring. Note that the air conditioner 10 is not limited to this example.

The indoor unit 11 includes a housing 21 , a heat exchanger 22 , a fan 23 , a filter 24 , two wind direction plates 25 , and two ventilation members 26 . The wind direction plate 25 and the ventilation member 26 may also be referred to as a louver.

As shown in the drawings, the X, Y, and Z axes are defined herein for convenience. The X-axis, Y-axis, and Z-axis are orthogonal 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.

Additionally, the X direction, Y direction and Z direction are defined herein. 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 which is the opposite direction 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 this embodiment, the +Z direction is the upward direction, and the -Z direction is the downward direction.

The housing 21 is formed into a substantially rectangular parallelepiped shape extending in the X direction. Note that the housing 21 may be formed in other shapes. For example, the housing 21 is hung on a wall of 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.

The housing 21 is provided with a ventilation passage 31, an inlet 32, and an outlet 33. The ventilation path 31 is provided inside the housing 21 . The suction port 32 opens on the upper surface 21a of the housing 21. The air outlet 33 opens on the lower surface 21b of the housing 21. The suction port 32 and the blowout port 33 may be opened in other parts of the housing 21.

The indoor unit 11 can pass air through the ventilation path 31. Wind is a flow of gas such as air. The suction port 32 is provided at one end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 11 . The air outlet 33 is provided at the other end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 11 . In other words, the ventilation passage 31 is provided between the inlet 32 and the outlet 33 inside the housing 21 .

Heat exchanger 22 is provided in ventilation passage 31 . The heat exchanger 22 includes, for example, refrigerant piping and a plurality of fins. The heat exchanger 22 exchanges heat with surrounding gas in the ventilation passage 31. Thereby, the heat exchanger 22 cools the air flowing through the ventilation path 31 during the cooling operation, and heats the air flowing through the ventilation path 31 during the heating operation.

The fan 23 is provided in the ventilation path 31. The fan 23 sends air from the suction port 32 to the blowout port 33 in the ventilation path 31 by rotating around a rotation axis Axf extending in the X direction. Thereby, the indoor unit 11 sucks indoor air into the ventilation passage 31 from the suction port 32 and blows out the air (wind) in the ventilation passage 31 from the outlet 33. Therefore, in this specification, the side of the ventilation passage 31 that is closer to the suction port 32 is referred to as upstream, and the side that is closer to the outlet 33 is referred to as downstream.

Fan 23 is located downstream of heat exchanger 22. Therefore, when the fan 23 generates wind, the air sucked in from the suction port 32 passes through the fins of the heat exchanger 22. Thereby, the air flowing through the ventilation path 31 exchanges heat with the heat exchanger 22.

The filter 24 is provided at the suction port 32 or near the suction port 32 in the ventilation path 31 . Filter 24 is located upstream of heat exchanger 22 . The filter 24 covers the suction port 32 from inside the housing 21 . For example, the filter 24 filters the air sucked in from the suction port 32 and captures dust in the air.

FIG. 2 is a cross-sectional view schematically showing the indoor unit 11 in operation according to the first embodiment. The two wind direction plates 25 are provided at or near the outlet 33 . The wind direction plate 25 is located downstream of the fan 23. The two wind direction plates 25 are arranged, for example, in parallel in the substantially Y direction along the lower surface 21b.

The two wind direction plates 25 are each movable between a first closed position Pc1 shown in FIG. 1 and a first open position Po1 shown in FIG. 2. Note that the two wind direction plates 25 can be individually moved between the first closed position Pc1 and the first open position Po1.

As shown in FIG. 1, the wind direction plate 25 located at the first closed position Pc1 covers a part of the air outlet 33. When the two wind direction plates 25 are both located at the first closed position Pc1, the two wind direction plates 25 cover almost the entire area of the air outlet 33.

As shown in FIG. 2, the wind direction plate 25 located at the first opening position Po1 opens a part of the air outlet 33. When the two wind direction plates 25 are both located at the first opening position Po1, the two wind direction plates 25 open almost the entire area of the air outlet 33.

The first opening position Po1 includes various positions where the wind direction plate 25 opens a part of the air outlet 33. For example, the first opening position Po1 includes a position where the wind direction plate 25 faces in a substantially horizontal direction as shown in FIG. 2, a position where the wind direction board 25 faces downward, and a plurality of positions between these two positions. . That is, the wind direction plate 25 is rotatable between a position facing substantially horizontally and a position facing downward. The wind direction plate 25 located at the first opening position Po1 adjusts the vertical direction of the air discharged from the outlet 33 depending on the direction of the wind direction plate 25. That is, as the wind direction plate 25 is oriented in a substantially horizontal direction as shown in FIG. 2, the indoor unit 11 emits wind in a substantially horizontal direction. On the other hand, since the wind direction plate 25 faces downward, the indoor unit 11 emits wind downward.

The indoor unit 11 may further include a left-right wind direction plate that adjusts the left-right direction of the wind discharged from the air outlet 33. The left and right wind direction plates are provided in the ventilation passage 31, for example. The indoor unit 11 can emit wind in the direction in which the left and right wind direction plates face.

The wind direction plate 25 is made of synthetic resin, for example. The wind deflector 25 may be made of other materials such as metal. The two wind direction plates 25 each have a shaft portion 41 and a plate portion 42.

The shaft portion 41 is formed into a substantially cylindrical shape extending in the X direction. The shaft portion 41 is rotatably supported by the housing 21 around a rotation axis Axl extending in the X direction. Note that each of the plurality of wind direction plates 25 has an 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 into a substantially rectangular plate shape extending in the X direction. By rotating the shaft portion 41 around the rotation axis Axl, the wind direction plate 25 can be moved between the first closed position Pc1 and the first open position Po1.

In the following description, the two wind direction plates 25 may be individually referred to as wind direction plates 25A and 25B. In other words, the two wind direction plates 25 include a wind direction plate 25A and a wind direction plate 25B. Note that the explanation common to the wind direction plates 25A and 25B will be described as the explanation about the wind direction plate 25.

The wind direction plate 25A is located between the upper end 33a of the outlet 33 and the lower end 33b of the outlet 33 in the Z direction. The wind direction plate 25B is located near the lower end 33b of the air outlet 33. The wind direction plate 25A is closer to the upper end 33a of the outlet 33 than the wind direction plate 25B. The wind direction plate 25B is closer to the lower end 33b of the air outlet 33 than the wind direction plate 25A.

The wind direction plates 25A and 25B located at the first open position Po1 partition the air outlet 33 into two flow paths C1 and C2. The flow path C1 is a part of the outlet 33 and is located between the wind direction plate 25A and the upper end 33a of the outlet 33. The flow path C2 is a part of the outlet 33 and is located between the wind direction plate 25A and the lower end 33b of the outlet 33. In other words, the flow path C2 is located between the wind direction plate 25A and the wind direction plate 25B.

The wind direction plate 25A opens the flow path C1 at the first open position Po1 and covers the flow path C1 at the first closed position Pc1. The wind direction plate 25B opens the flow path C2 at the first open position Po1 and covers the flow path C2 at the first closed position Pc1.

The two ventilation members 26 are provided at or near the outlet 33 . The ventilation member 26 is located downstream of the fan 23. The two ventilation members 26 are arranged, for example, in parallel in the Y direction.

The two ventilation members 26 are each movable 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. In other words, the ventilation member 26 can be placed in the second closed position Pc2. Note that the two ventilation members 26 can be individually moved between the second closed position Pc2 and the second open position Po2.

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 a ventilation member 26A and a ventilation member 26B. Note that the description common to the ventilation members 26A and 26B will be described as the description for the ventilation member 26.

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

The ventilation member 26 located at the second closed position Pc2 covers a part of the air outlet 33 opened by the wind direction plate 25 located at the first open position Po1. In this embodiment, the ventilation member 26A located at the second closed position Pc2 covers the flow path C1 opened by the wind direction plate 25A located at the first open position Po1. Further, the ventilation member 26B located at the second closed position Pc2 covers the flow path C2 opened by the wind direction plate 25B located at the first open position Po1.

When the two ventilation members 26 are both located in the second closed position Pc2, the two ventilation members 26 cover all the channels C1 and C2. Note that 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 communicate with the room without being covered by the ventilation member 26 in the X direction, or the air may be able to pass through a gap between the ventilation member 26 and the wind direction plate 25. . In this embodiment, most of the flow paths C1 and C2 need only be covered by the ventilation members 26A and 26B when viewed in the direction in which the wind travels. Note that the manner in which the ventilation member 26 covers the air outlet 33 is not limited to this example.

The ventilation member 26 located at the second opening position Po2 opens a part of the air outlet 33 opened by the wind direction plate 25 located at the first opening position Po1. In this embodiment, the ventilation member 26A located at the second opening position Po2 opens the flow path C1 opened by the wind direction plate 25A located at the first opening position Po1. Further, the ventilation member 26B located at the second opening position Po2 opens the flow path C2 opened by the wind direction plate 25B located at the first opening position Po1.

The ventilation member 26 is made of synthetic resin, for example. Ventilation member 26 may be made of other materials such as metal. The two ventilation members 26 each have a shaft portion 51 and a plate portion 52.

The shaft portion 51 is formed in a substantially cylindrical shape extending in the X direction. The shaft portion 51 is rotatably supported by the housing 21 around a rotation axis Axc extending in the X direction. Note that each of the plurality of ventilation members 26 has an individual 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 into a substantially rectangular plate shape extending in the X direction. By rotating the shaft portion 51 around the rotation axis Axc, the ventilation member 26 can be moved between the second closed position Pc2 and the second open position Po2.

The shaft portion 51 of the ventilation member 26 is spaced upward from the plate portion 42 of the wind direction plate 25 located at 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 wind direction plate 25.

The tip 52a of the plate portion 52 of the ventilation member 26 located in the second closed position Pc2 is in contact with the plate portion 42 of the wind direction plate 25, or is arranged near the plate portion 42. Thereby, the ventilation member 26 located at the second closed position Pc2 covers a part of the air outlet 33 opened by the wind direction plate 25 located at the first open position Po1. The tip 52a is an end of the plate portion 52 located on the opposite side of the shaft portion 51.

The length of the plate portion 52 in the X direction is approximately equal to the length of the air outlet 33 in the X direction. Thereby, the ventilation members 26A and 26B located in the second closed position Pc2 can cover most of the flow paths C1 and C2.

The length of the plate part 52 in the direction in which the plate part 52 protrudes from the shaft part 51 is shorter than the maximum length of each of the channels C1 and C2 in the Z direction. Thereby, when the ventilation member 26 moves between the second closed position Pc2 and the second open position Po2, interference with the wind direction plate 25 is suppressed.

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

When the two ventilation members 26 are both located at the second opening position Po2, the two ventilation members 26 open almost the entire area of the air outlet 33 that is opened by the wind direction plate 25 located at the first opening position Po1. . Note that even if the two ventilation members 26 are located at the second open position Po2, if the wind direction plate 25 is located at the first closed position Pc1, the flow paths C1 and C2 are covered by the corresponding wind direction plate 25. .

As shown in FIG. 1, the ventilation member 26A located at the second open position Po2 is accommodated in the recess 21c of the housing 21 provided near the outlet 33. The depression 21c is recessed from the inner surface 21d of the housing 21, which forms a part of the ventilation passage 31. The ventilation member 26A located at the second open position Po2 is suppressed from interfering with the wind flowing through the ventilation path 31 by being accommodated in the depression 21c.

The ventilation member 26B is provided in the ventilation passage 31 near the outlet 33. The plate portion 52 of the ventilation member 26B located at the second open position Po2 extends in the direction along the flow of the wind in the ventilation path 31. Thereby, the ventilation member 26B located at the second open position Po2 is restrained from interfering with the wind flowing through the ventilation path 31. Note that the arrangement of the ventilation members 26A and 26B located at the second open position Po2 is not limited to the above example.

FIG. 3 is a front view schematically showing a portion of the wind direction plate 25 and ventilation member 26 of the first embodiment. FIG. 4 is a cross-sectional view schematically showing 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 ports 55 and a plurality of second ventilation ports 56. Note that each of the ventilation members 26 may be provided with one first ventilation port 55 and one second ventilation port 56.

As shown in FIG. 4, each of the plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 is a through hole that penetrates the plate portion 52. Therefore, the plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 open on the inner surface 52b and the outer surface 52c of the plate portion 52, respectively.

The plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 are arranged alternately in the arrangement direction Dp. Therefore, the first ventilation port 55 and the second ventilation port 56 are provided side by side in the arrangement direction Dp. The arrangement direction Dp is an example of a first direction, and is a direction along the outer surface 52c of the plate portion 52.

In this embodiment, the arrangement direction Dp is approximately equal to the direction in which the plate portion 52 extends from the shaft portion 51. Further, when the ventilation member 26 is located at 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.

As shown in FIG. 3, the first ventilation port 55 is a substantially rectangular slit extending in the X direction. The X direction is an example of a second direction, and is a direction along the outer surface 52c of the plate portion 52 and intersecting with the arrangement direction Dp. Note that the first ventilation port 55 may be a hole having a circular, square, triangular, or other shaped cross section. The plurality of first ventilation ports 55 are arranged in the arrangement direction Dp.

The second ventilation port 56 is a hole having a circular cross section. Note that the second ventilation port 56 may be a hole having a cross section of a square, a triangle, or another shape. In this embodiment, the cross section of the first ventilation port 55 and the second ventilation port 56 is a cross section perpendicular to the direction in which the first ventilation port 55 and the second ventilation port 56 penetrate the plate portion 52.

The plurality of second ventilation holes 56 are arranged in the X direction. In other words, the plurality of second ventilation holes 56 are arranged at intervals in the X direction. Therefore, the plurality of second ventilation ports 56 form a row 58 of the plurality of second ventilation ports 56 lined up in the X direction. In the plate portion 52, a plurality of rows 58 are arranged in the arrangement direction Dp. The plurality of second ventilation ports 56 may be arranged in a grid pattern or in a staggered pattern.

In this embodiment, a plurality of slit-shaped first ventilation ports 55 and rows 58 of second ventilation ports 56 are arranged alternately in the arrangement direction Dp. Therefore, the plurality of first ventilation ports 55 and the plurality of second ventilation ports 56 form a row 59 of first ventilation ports 55 and second ventilation ports 56 lined up in the arrangement direction Dp.

The first ventilation ports 55 are arranged at both ends of the row 59 of the first ventilation ports 55 and the second ventilation ports 56 arranged in the arrangement direction Dp. Therefore, in the arrangement direction Dp, the plurality of second ventilation holes 56 are located between two of the plurality of first ventilation holes 55.

FIG. 5 is a front view schematically showing a part of the wind direction plate 25 and the ventilation member 26 of the first modification of the first embodiment. As shown in FIG. 5, the second ventilation port 56 may be arranged at the end of the row 59 of the first ventilation port 55 and the second ventilation port 56 lined up in the arrangement direction Dp. In this case, the plurality of first ventilation holes 55 are located between two of the plurality of second ventilation holes 56 in the arrangement direction Dp.

As shown in FIG. 3, the cross-section of each of the second ventilation holes 56 is smaller than the cross-section of each of the first ventilation holes 55. Further, the total cross section of the plurality of second ventilation holes 56 included in each of the plurality of rows 58 is smaller than the cross section of one of the plurality of first ventilation holes 55.

As shown in FIG. 4, each of the plurality of first ventilation ports 55 has an enlarged portion 61 and a straight portion 62. The enlarged portion 61 and the straight portion 62 are each part of the first ventilation port 55. The enlarged portion 61 and the straight portion 62 are continuous in the thickness direction from the inner surface 52b to the outer surface 52c of the plate portion 52.

The enlarged portion 61 is a portion that is open to the outer surface 52c of the plate portion 52 and whose cross section becomes larger as it approaches the outer surface 52c. In other words, the enlarged portion 61 is a portion whose cross section decreases from the outer surface 52c toward the inner surface 52b. Further, as the enlarged portion 61 approaches the outer surface 52c, it approaches the adjacent second ventilation port 56.

The straight portion 62 opens to the inner surface 52b and is connected to the enlarged portion 61. The straight portion 62 has 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.

The diameter of the enlarged portion 61 at its largest portion is set to, for example, 3 to 5 mm. Further, the diameters of the smallest part of the enlarged part 61 and the straight part 62 are set to, for example, 50 to 90% of the diameter of the largest part of the enlarged part 61. Note that the size of the first ventilation port 55 is not limited to this example.

Each of the plurality of second ventilation ports 56 also has an enlarged portion 65 and a straight portion 66. The enlarged portion 65 and the straight portion 66 are each 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 to the outer surface 52c of the plate portion 52.

The enlarged portion 65 is a portion that is open to the outer surface 52c of the plate portion 52 and whose cross section becomes larger as it approaches the outer surface 52c. In other words, the enlarged portion 65 is a portion whose cross section decreases from the outer surface 52c toward the inner surface 52b. Furthermore, the enlarged portion 65 approaches the adjacent first ventilation port 55 as it approaches the outer surface 52c.

The straight portion 66 opens to the inner surface 52b and is connected to the enlarged portion 65. The straight portion 66 has 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.

FIG. 6 is a cross-sectional view schematically showing the ventilation member 26 of the second modification of the first embodiment. As shown in FIG. 6, the first ventilation port 55 may have a reduced portion 68 instead of the straight portion 62. The reduced portion 68 opens on the inner surface 52b of the plate portion 52 and is connected to the enlarged portion 61. The reduced portion 68 is a portion whose cross section decreases as it approaches the enlarged portion 61.

The second ventilation port 56 may have a reduced portion 69 instead of the straight portion 62. The reduced portion 69 opens on the inner surface 52b of the plate portion 52 and is connected to the enlarged portion 65. The reduced portion 69 is a portion whose cross section decreases as it approaches the enlarged portion 65.

The first ventilation port 55 and the second ventilation port 56 are not limited to these examples. For example, the first ventilation port 55 may have one of an enlarged portion 61, a straight portion 62, and a reduced portion 68. Similarly, the second ventilation port 56 may have one of an enlarged portion 65, a straight portion 66, and a reduced portion 69.

FIG. 7 is a block diagram schematically showing the configuration of the indoor unit 11 of the first embodiment. As shown in FIG. 7, the indoor unit 11 includes a control device 80, a first drive circuit 81, a second drive circuit 82, a third drive circuit 83, a fan motor 84, and two wind direction plates. It further includes motors 85 and 86, two switching motors 87 and 88, and a receiving device 89.

The control device 80, the first drive circuit 81, the second drive circuit 82, the third drive circuit 83, the fan motor 84, the wind direction plate motors 85, 86, the switching motors 87, 88, and the receiving device 89 are housed in a housing. It is housed in 21.

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.

The controller 80 controls the operation of the air conditioner 10 by having the processor read and execute the program from the storage device. The control device 80 is connected to, for example, a first drive circuit 81, a second drive circuit 82, a third drive circuit 83, and a reception device 89.

The first drive circuit 81 is a drive circuit for the fan motor 84. The fan motor 84 rotates the fan 23 around the rotation axis Axf. The control device 80 controls the fan motor 84 and the fan 23 by controlling the first drive circuit 81 .

The second drive circuit 82 is a drive circuit for the two wind direction plate motors 85 and 86. The wind direction plate motors 85 and 86 each rotate the corresponding wind direction plate 25 around the rotation axis Axl. In this embodiment, the wind direction plate motor 85 rotates the wind direction plate 25A around the rotation axis Axl of the wind direction plate 25A. The wind direction plate motor 86 rotates the wind direction plate 25B around the rotation axis Axl of the wind direction plate 25B. The control device 80 controls the wind direction plate motors 85 and 86 and the wind direction plates 25A and 25B by controlling the second drive circuit 82.

The third drive circuit 83 is a drive circuit for two switching motors 87 and 88. The switching motors 87 and 88 each rotate the corresponding ventilation member 26 around the rotation axis Axc. In this embodiment, the switching motor 87 rotates the ventilation member 26A around the rotation axis Axc of the ventilation member 26A. The switching motor 88 rotates the ventilation member 26B around the rotation axis Axc of the ventilation member 26B. The control device 80 controls the switching motors 87 and 88 and the ventilation members 26A and 26B by controlling the third drive circuit 83.

The receiving device 89 receives, for example, a wireless signal such as electromagnetic waves or infrared rays from the remote controller 89a. The control device 80 acquires, from the receiving device 89, an instruction signal from the remote controller 89a.

An example of the operation of the indoor unit 11 will be described below. Note that the operation of the indoor unit 11 is not limited to the following example. The indoor unit 11 of this embodiment can be operated in a first mode and a second mode. In the first mode, the indoor unit 11 supplies wind indoors that is closer to natural wind. In the second mode, the indoor unit 11 supplies air indoors that tends to make the user feel cold or warm. Note that the indoor unit 11 can be operated in the first mode and the second mode during both cooling operation and heating operation.

In the first mode, the control device 80 controls the second drive circuit 82 to arrange the wind direction plates 25A, 25B at the first open position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation members 26A, 26B at the second closed position Pc2.

For example, the control device 80 controls the second drive circuit 82 to rotate the wind direction plates 25A, 25B around the rotation axis Axl. Thereby, the wind direction plates 25A and 25B move to the first opening position Po1 and open the air outlet 33.

The control device 80 arranges the wind direction plates 25A and 25B so that the size of the flow paths C1 and C2 in the Z direction is longer than the length of the plate portion 52 of the ventilation member 26 in the arrangement direction Dp. For example, the control device 80 arranges the wind direction plates 25A, 25B so that the wind direction plates 25A, 25B extend substantially downward. In this state, the control device 80 drives the third drive circuit 83 to rotate the ventilation members 26A, 26B around the rotation axis Axc. Thereby, the ventilation members 26A, 26B move to the second closed position Pc2. Since the size of the channels C1 and C2 in the Z direction is longer than the length of the plate portion 52 in the arrangement direction Dp, interference of the ventilation member 26 with the wind direction plate 25 is suppressed.

The control device 80 further controls the second drive circuit 82 to move the wind direction plates 25A, 25B closer to the tips 52a of the plate portions 52 of the ventilation members 26A, 26B. This narrows the gap between the ventilation members 26A, 26B and the wind direction plates 25A, 25B, and the ventilation members 26A, 26B cover most of the flow paths C1, C2.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send air from the suction port 32 to the blowout port 33 . Note that the fan 23 may start blowing air after the ventilation member 26 moves to the second closed position Pc2, or the ventilation member 26 moves to the second closed position Pc2 while the fan 23 is sending air. You may do so.

The air sent by the fan 23 passes through the ventilation path 31 and reaches the outlet 33. The air outlet 33 is covered by the ventilation member 26 located at the second closed position Pc2. Therefore, the air sent by the fan 23 passes through the first ventilation port 55 and the second ventilation port 56 of the ventilation member 26 and is discharged to the outside of the indoor unit 11 .

As shown in FIG. 4, a part of the air sent by the fan 23 is discharged from the first ventilation port 55 to the outside of the indoor unit 11 as the first air W1. The cross section of the first ventilation hole 55 is set larger than the cross section of the second ventilation hole 56. Therefore, the flow velocity of the first wind W1 becomes relatively slow. In this embodiment, the first wind W1 is discharged to the outside of the indoor unit 11 as a laminar flow.

On the other hand, the other part of the air sent by the fan 23 is released from the second ventilation port 56 to the outside of the indoor unit 11 as second air W2. The cross section of the second ventilation hole 56 is set smaller than the cross section of the first ventilation hole 55. Therefore, the flow velocity of the second wind W2 becomes relatively fast. In this embodiment, the second wind W2 is discharged to the outside of the indoor unit 11 as a laminar flow, and then transitions to a turbulent flow. The second wind W2 is more likely to transition to turbulence than the first wind W1. Note that the second wind W2 may be discharged to the outside of the indoor unit 11 as a turbulent flow.

For example, the second wind W2 is a jet stream blowing out from the second ventilation port 56. The jet stream has a high flow rate and stirs the air inside the jet stream by drawing in surrounding air. In addition, the jet stream becomes turbulent and tends to generate vortices.

The first ventilation holes 55 and the second ventilation holes 56 are arranged alternately and adjacent to each other. Therefore, the first wind W1 discharged from the first ventilation port 55 and the second wind W2 discharged from the second ventilation port 56 flow side by side.

Since the second wind W2 has a high flow velocity, it draws in the first wind W1. Thereby, the first wind W1 hits the second wind W2. Further, the second wind W2 that has transitioned to turbulence is diffused and hits the first wind W1 that flows adjacent to the second wind W2. In this way, the first wind W1 and the second wind W2 having different flow speeds and conditions (laminar flow or turbulent flow) flow adjacent to each other and collide with each other. That is, the first wind W1 that has passed through the first ventilation port 55 and the second wind W2 that has passed through the second ventilation port 56 interfere with each other.

Furthermore, the first ventilation port 55 has an enlarged portion 61. Therefore, a part of the first wind W1 released from the first ventilation port 55 is directed toward the second wind W2 released from the second ventilation port 56 adjacent to the first ventilation port 55. It flows. This makes it easier for the first wind W1 to hit the second wind W2.

Similarly, the second ventilation port 56 has an enlarged portion 65. Therefore, a part of the second wind W2 released from the second ventilation port 56 is directed toward the first wind W1 released from the first ventilation port 55 adjacent to the second ventilation port 56. It flows. This makes it easier for the second wind W2 to hit the first wind W1.

When the first wind W1 and the second wind W2 hit each other, for example, a lump of the first wind W1 and the second wind W2 is broken up, and the second wind W2, which is a turbulent flow, becomes the first wind W2. It is carried by wind W1. The first wind W1 and the second wind W2 cause such various interactions and generate a turbulent flow Ws that spreads over a wide range. The turbulent flow Ws is closer to natural wind than the wind immediately after being discharged from the outlet 33.

In general, turbulent flow moves in one direction macroscopically, but microscopically the movement direction of particles of fluid in the turbulent flow is disordered, so energy loss is greater than in laminar flow. For this reason, turbulent wind is easily attenuated and disappears as it assimilates into the atmosphere over a shorter distance than laminar wind. However, the turbulent flow Ws generated in the first mode is more difficult to attenuate than simple turbulence because, for example, the first wind W1, which is a laminar flow, propels the second wind W2, which is a turbulent flow. Therefore, the turbulent flow Ws tends to reach a longer distance from the indoor unit 11 than, for example, the second wind W2 alone which has transitioned to a turbulent flow.

On the other hand, in the second mode, the control device 80 controls the second drive circuit 82 to arrange the wind direction plates 25A, 25B at the first open position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation members 26A, 26B at the second open position Po2.

As shown in FIG. 1, for example, in an initial state in which the air conditioner 10 is not operating, the ventilation member 26 is arranged at the second open position Po2. Therefore, when the air conditioner 10 starts operating in the second mode from the initial state, the control device 80 maintains the ventilation member 26 at the second open position Po2.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send air from the suction port 32 to the blowout port 33 . The air sent by the fan 23 passes through the ventilation path 31 and is discharged to the outside of the indoor unit 11 from the air outlet 33. Since the ventilation member 26 is located at the second opening position Po2, the air sent by the fan 23 is directed from the air outlet 33 to the indoor unit 11 without passing through the first ventilation port 55 and the second ventilation port 56. Released directly to the outside. Note that a portion of the air sent by the fan 23 may pass through the first ventilation port 55 or the second ventilation port 56.

The wind discharged from the outlet 33 in the second mode has a narrower flow range and a faster flow velocity than the turbulent flow Ws generated in the first mode. When the wind hits the user, the user tends to feel colder or warmer more strongly. For example, the wind has a high velocity and hits the user locally, making the user feel colder or warmer. On the other hand, if the wind hits the user, there is a possibility that the user may feel uncomfortable.

The turbulent flow Ws generated in the first mode is closer to natural wind than the wind discharged from the outlet 33 in the second mode. Generally, users are less likely to experience discomfort from wind that is close to natural wind. Therefore, the air conditioner 10 generates a turbulent flow Ws that makes it difficult for the user to feel uncomfortable in the first mode, and blows out wind that makes the user feel cold or warm in the second mode.

The control device 80 can switch operation between a first mode and a second mode. For example, the control device 80 switches between the first mode and the second mode based on an instruction signal from the remote controller 89a. The control device 80 is not limited to this example, and can switch between the first mode and the second mode based on various conditions such as the number of users in the room, their positions, or characteristics, the temperature in the room, and the time of day. may be switched automatically.

In the air conditioner 10 according to the first embodiment described above, the ventilation member 26 has a second opening that covers at least a portion of the air outlet 33 opened by the wind direction plate 25 located at the first opening position Po1. It can be placed in the closed position Pc2. The ventilation member 26 has a first ventilation port 55 that opens to the inner surface 52b and the outer surface 52c, and a second ventilation port 56 that opens to the inner surface 52b and the outer surface 52c and has a smaller cross section than the first ventilation port 55. They are arranged in the arrangement direction Dp along the outer surface 52c. When the ventilation member 26 is placed in the second closed position Pc2, the air sent by the fan 23 passes through the first ventilation port 55 and the second ventilation port 56 and is discharged to the outside. Since the cross section of the second ventilation port 56 is smaller than the cross section of the first ventilation port 55, the first wind W1 passing through the first ventilation port 55 and the second wind W2 passing through the second ventilation port 56. have different flow velocities. Since the first ventilation port 55 and the second ventilation port 56 are arranged side by side, the first wind W1 and the second wind W2 have a difference in flow velocity and a difference in ease of transition to turbulence. Due to various factors, turbulent flows Ws that hit each other outside the air conditioner 10 and spread over a wide range are generated. The turbulent flow Ws is closer to natural wind than the wind released from the outlet 33 without passing through the first ventilation port 55 and the second ventilation port 56. Therefore, the air conditioner 10 of this embodiment makes it possible to make the wind hitting the user closer to natural wind, thereby reducing the user's discomfort.

The ventilation member 26 is provided with a plurality of first ventilation ports 55 and a plurality of second ventilation ports 56. The plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 are arranged alternately in the arrangement direction Dp along the outer surface 52c. This makes it easier for the first wind W1 and the second wind W2 to hit each other outside the air conditioner 10. Therefore, the air conditioner 10 easily generates turbulent flow Ws that is closer to natural wind.

In the arrangement direction Dp, at least one of the plurality of second ventilation ports 56 is located between two of the plurality of first ventilation ports 55. Since the cross section of the second ventilation port 56 is smaller than the cross section of the first ventilation port 55, the second wind W2 is more likely to transition to turbulence than the first wind W1. On the other hand, since the cross section of the first ventilation port 55 is larger than the cross section of the second ventilation port 56, the first wind W1 is more likely to form a laminar flow than the second wind W2. Therefore, the second wind W2 that has transitioned to a turbulent flow is located between the two first winds W1 that are laminar flows. Laminar flow loses less energy and can reach farther than turbulent flow. Therefore, the air conditioner 10 can propel the second wind W2 that has transitioned to a turbulent flow into the first wind W1 that is a laminar flow, and can deliver the generated turbulent flow Ws, which is similar to natural wind, further away. becomes.

The plurality of first ventilation holes 55 extend along the outer surface 52c and in the X direction intersecting the arrangement direction Dp. The plurality of second ventilation holes 56 are arranged in the X direction. That is, the first ventilation port 55 is a slit, and the second ventilation port 56 is a hole smaller than the slit. As a result, the first wind W1 becomes more likely to become a laminar flow, and the second wind W2 becomes more likely to become a turbulent flow. Therefore, the air conditioner 10 can propel the second wind W2 that has transitioned to a turbulent flow into the first wind W1 that is a laminar flow, and can deliver the generated turbulent flow Ws, which is similar to natural wind, further away. becomes.

At least one of the plurality of first ventilation holes 55 and the plurality of second ventilation holes 56 each has enlarged portions 61 and 65 that are open to the outer surface 52c and whose cross sections expand as they approach the outer surface 52c. Thereby, the wind passing through the enlarged portions 61 and 65 easily hits other wind passing through the first ventilation opening 55 and the second ventilation opening 56. Therefore, the air conditioner 10 easily generates turbulent flow Ws that is closer to natural wind.

The wind direction plate 25 located at the first opening position Po1 divides the air outlet 33 into a plurality of flow paths C1 and C2. The ventilation members 26A, 26B located in the second closed position Pc2 cover all the channels C1, C2. Thereby, the air conditioner 10 can suppress the wind discharged from the air outlet 33 from directly reaching the user without passing through the first ventilation hole 55 and the second ventilation hole 56.

The ventilation member 26 is located between a second closed position Pc2 and a second open position Po2 in which at least a portion of the outlet 33 opened by the wind direction plate 25 located at the first open position Po1 is opened. It is movable. Therefore, the air conditioner 10 can release the wind released from the air outlet 33 to the outside of the air conditioner 10 without passing through the first ventilation port 55 and the second ventilation port 56. The wind discharged from the air outlet 33 can make the user feel colder or warmer.

In the first mode, the control device 80 arranges the wind direction plate 25 at the first open position Po1, arranges the ventilation member 26 at the second closed position Pc2, and directs the fan 23 from the inlet 32 to the outlet 33. Let the wind blow. In this case, the first wind W1 is discharged to the outside from the first ventilation port 55, and the second wind W2, which is more likely to become turbulent than the first wind W1, is discharged to the outside from the second ventilation port 56. be done. As a result, the first wind W1 and the second wind W2 hit each other outside the air conditioner 10, generating a turbulent flow Ws that spreads over a wide range. On the other hand, in the second mode, the control device 80 arranges the wind direction plate 25 at the first opening position Po1, arranges the ventilation member 26 at the second opening position Po2, and controls the fan 23 from the suction port 32 to the air outlet. Let the wind flow to 33. In this case, the wind is discharged to the outside from the air outlet 33 without passing through the first ventilation port 55 and the second ventilation port 56 . Therefore, the air conditioner 10 can be operated in a first mode in which wind closer to natural wind is emitted, or in a second mode in which wind that is more likely to be perceived as cold or warm is emitted, depending on the user's request, for example. It is possible to drive in mode.

In the first embodiment described above, the flow paths C1 and C2 are covered by ventilation members 26A and 26B. However, either one of the channels C1 and C2 may be open without being covered by the wind direction plates 25A, 25B and the ventilation members 26A, 26B. In this case, the flow rate of the air discharged from the open flow path C1 or flow path C2 passes through the first ventilation port 55 or the second ventilation port 56 of the ventilation member 26 that covers the flow path C1 or flow path C2. The velocity of the wind is slower than that of the wind. Therefore, the wind released from the open flow path C1 or the flow path C2 is caught up in the wind passing through the first ventilation port 55 or the second ventilation port 56 of the ventilation member 26 and hits the air.

The wind released from the open flow path C1 or the flow path C2 and the wind that has passed through the first ventilation port 55 or the second ventilation port 56 of the ventilation member 26 are crushed, for example, by hitting each other. , generating turbulence that spreads over a wide area. The turbulent flow is closer to natural wind than the wind released from open channel C1 or channel C2. Therefore, the air conditioner 10 can make the wind hitting the user more similar to natural wind, thereby reducing the user's discomfort.

(Second embodiment)
A second embodiment will be described below with reference to FIG. 8. In addition, in the description of multiple embodiments below, components having the same functions as already described components are given the same reference numerals as the already described components, and further explanation may be omitted. . Furthermore, the plurality of components labeled with the same reference numerals do not necessarily have all functions and properties in common, and may have different functions and properties depending on each embodiment.

FIG. 8 is a cross-sectional view schematically showing the indoor unit 11 of the air conditioner 10 according to the second embodiment. As shown in FIG. 8, the indoor unit 11 of the second embodiment has a ventilation member 26A and does not have a ventilation member 26B. That is, in the second embodiment, the number of ventilation members 26 is smaller than the number of channels C1 and C2.

In the second embodiment, in the first mode, the control device 80 arranges the wind direction plate 25A at the first open position Po1 by controlling the second drive circuit 82. On the other hand, the control device 80 controls the second drive circuit 82 to arrange the wind direction plate 25B at the first closed position Pc1. As a result, the flow path C1 is opened by the wind direction plate 25A located at the first open position Po1, and the flow path C2 is covered by the wind direction board 25B located at the first closed position Pc1. In FIG. 8, the wind direction plate 25B located at the first closed position Pc1 is shown by a solid line, and the wind direction board 25B located at the first open position Po1 is shown by a two-dot chain line.

Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation member 26A at the second closed position Pc2. As a result, the flow path C1 of the air outlet 33 that is opened by the wind direction plate 25A located at the first opening position Po1 is covered by the ventilation member 26A. FIG. 8 shows the ventilation member 26A located in the second closed position Pc2 with a solid line, and the ventilation member 26A located in the second open position Po2 with a chain double-dashed line.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send air from the suction port 32 to the blowout port 33 . The air sent by the fan 23 passes through the ventilation path 31 and reaches the outlet 33.

The flow path C2 of the outlet 33 is covered by the wind direction plate 25B. On the other hand, the flow path C1 of the outlet 33 is covered by the ventilation member 26A located at the second closed position Pc2. Therefore, the air sent by the fan 23 is discharged to the outside of the indoor unit 11 through the first ventilation port 55 and the second ventilation port 56 of the ventilation member 26A. As a result, as in the first embodiment, the first wind W1 discharged from the first ventilation port 55 and the second wind W2 discharged from the second ventilation port 56 hit each other, creating turbulent flow. Generate Ws.

In the air conditioner 10 of the second embodiment described above, the number of ventilation members 26 is smaller than the number of the plurality of flow paths C1 and C2. Of the air outlet 33, the flow path C2 is covered by the wind direction plate 25B, and the flow path C1 is covered by the ventilation member 26A. Thereby, even if the number of ventilation members 26 is less than the number of channels C1 and C2 partitioned by the wind direction plate 25, the ventilation members 26 can cover all the open channels C1. Therefore, the number of parts of the air conditioner 10 can be reduced, and the structure of the air conditioner 10 can be simplified. That is, when the outlet 33 is divided into a plurality of channels C1 and C2, the air conditioner 10 closes at least one channel C2 in the first mode, and closes the remaining channels C1 and C2. By opening C1 and covering it with the ventilation member 26A, the number of ventilation members 26 can be made smaller than the number of channels C1 and C2. Therefore, the number of ventilation members 26 can be reduced, and the structure of the air conditioner 10 can be simplified.

(Third embodiment)
A third embodiment will be described below with reference to FIG. 9. FIG. 9 is a sectional view schematically showing the indoor unit 11 of the air conditioner 10 according to the third embodiment. As shown in FIG. 9, in the third embodiment, the wind direction plate 25 has a wind direction plate 25C instead of the wind direction plates 25A and 25B. Furthermore, the ventilation member 26 has a ventilation member 26C instead of the ventilation members 26A and 26B.

It is possible to move. Further, the wind direction plate 25C has a shaft portion 41 and a plate portion 42, like the wind direction plates 25A and 25B of the first embodiment.

The wind direction plate 25C is located between the upper end 33a of the outlet 33 and the lower end 33b of the outlet 33 in the Z direction. The wind direction plate 25C located at the first closed position Pc1 covers a part of the air outlet 33. Further, the wind direction plate 25C located at the first opening position Po1 opens a part of the air outlet 33.

The wind direction plate 25C located at the first opening position Po1 divides the air outlet 33 into two flow paths C3 and C4. The flow path C3 is a part of the outlet 33 and is located between the wind direction plate 25C and the upper end 33a of the outlet 33. The flow path C4 is a part of the outlet 33 and is located between the wind direction plate 25C and the lower end 33b of the outlet 33.

The wind direction plate 25C opens the flow path C3 at the first open position Po1, and covers the flow path C3 at the first closed position Pc1. The flow path C4 is open both when the wind direction plate 25C is located at the first open position Po1 and when it is located at the first closed position Pc1.

The ventilation member 26C is movable between a second closed position Pc2 shown by a solid line in FIG. 9 and a second open position Po2 shown by a two-dot chain line in FIG. In other words, the ventilation member 26C can be placed in the second closed position Pc2. Further, the ventilation member 26 has a shaft portion 51 and a plate portion 52, like the ventilation members 26A and 26B of the first embodiment.

The shaft portion 51 of the ventilation member 26C is located near the lower end 33b of the air outlet 33. In the second closed position Pc2, the plate portion 52 of the ventilation member 26C extends between the upper end 33a and the lower end 33b of the air outlet 33. Therefore, the ventilation member 26C located at the second closed position Pc2 covers the flow paths C3 and C4. That is, the ventilation member 26C located at the second closed position Pc2 covers almost the entire area of the air outlet 33. Further, the ventilation member 26C located at the second closed position Pc2 covers the wind direction plate 25C.

The ventilation member 26C located at the second opening position Po2 opens the air outlet 33. Therefore, the ventilation member 26 located at the second opening position Po2 opens the flow path C3 and the flow path C4 opened by the wind direction plate 25 located at the first opening position Po1. In the third embodiment, the ventilation member 26C located at the second open position Po2 also functions as a wind direction plate and adjusts the direction of the wind discharged from the flow path C4.

Similar to the ventilation members 26A and 26B of the first embodiment, the ventilation member 26C is provided with a plurality of first ventilation ports 55 and a plurality of second ventilation ports 56. The first ventilation port 55 and the second ventilation port 56 may penetrate the ventilation member 26 in the thickness direction or in a predetermined direction.

In the third embodiment, in the first mode, the control device 80 arranges the wind direction plate 25C at the first open position Po1 by controlling the second drive circuit 82. In the third embodiment, the wind direction plate 25C is rotationally driven by a wind direction plate motor 85 controlled by the second drive circuit 82, for example.

Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation member 26C at the second closed position Pc2. In the third embodiment, the ventilation member 26C is rotationally driven by a switching motor 87 controlled by a third drive circuit 83, for example.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send air from the suction port 32 to the blowout port 33 . The air sent by the fan 23 passes through the ventilation path 31 and reaches the outlet 33. The air outlet 33 is covered by a ventilation member 26C located at the second closed position Pc2. Therefore, the air sent by the fan 23 is discharged to the outside of the indoor unit 11 through the first ventilation port 55 and the second ventilation port 56 of the ventilation member 26C. As a result, as in the first embodiment, the first wind W1 discharged from the first ventilation port 55 and the second wind W2 discharged from the second ventilation port 56 hit each other, creating turbulent flow. Generate Ws.

On the other hand, in the second mode, the control device 80 controls the second drive circuit 82 to arrange the wind direction plate 25C at the first open position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation member 26C at the second open position Po2. The ventilation member 26C serves as a wind direction plate and faces in the direction of the set wind direction.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send air from the suction port 32 to the blowout port 33 .
