(First Embodiment)
Hereinafter, the first embodiment will be described with reference to FIGS. 1 to 7. In this specification, the vertically upper direction is basically defined as the upward direction, and the vertically lower direction is defined as the downward direction. Further, in the present specification, the constituent elements according to the embodiment and the description of the elements may be described in a plurality of expressions. The components and their description are examples and are not limited by the representations herein. The components may also be identified by names different from those herein. The components may also be described by expressions different from those herein.

FIG. 1 is a cross-sectional view schematically showing an indoor unit 11 of the air conditioner 10 according to the first embodiment. As shown in FIG. 1, the air conditioner 10 has an indoor unit 11. The indoor unit 11 is arranged inside the building and is connected to the outdoor unit arranged outside via the refrigerant pipe and the electric wiring. The air conditioner 10 is not limited to this example.

The indoor unit 11 has 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 each drawing, the X-axis, Y-axis and Z-axis 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.

Further, in the present specification, the X direction, the Y direction and the Z direction are defined. The X direction is a direction along the X axis and includes the + X direction indicated by the arrow on the X axis and the −X direction which is the opposite direction of the arrow on the X axis. The Y direction is a direction along the Y axis and includes the + Y direction indicated by the arrow on the Y axis and the −Y direction which is the opposite direction of the arrow on the Y axis. The Z direction is a direction along the Z axis and includes the + Z direction indicated by the arrow on the Z axis and the −Z direction which is the opposite direction of the arrow on the Z axis. In the present embodiment, the + Z direction is the upward direction and the −Z direction is the downward direction.

The housing 21 is formed in a substantially rectangular parallelepiped shape extending in the X direction. The housing 21 may be formed in another shape. The housing 21 is hung on the wall of a building, for example. 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, a suction port 32, and an outlet 33. The ventilation passage 31 is provided inside the housing 21. The suction port 32 opens on the upper surface 21a of the housing 21. The outlet 33 opens to the lower surface 21b of the housing 21. The suction port 32 and the outlet 33 may be opened to other parts of the housing 21.

The indoor unit 11 can allow air to pass through the ventilation passage 31. Wind is a stream 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 to the outside of the indoor unit 11. The outlet 33 is provided at the other end of the ventilation passage 31, and communicates the ventilation passage 31 to the outside of the indoor unit 11. In other words, the ventilation passage 31 is provided between the suction port 32 and the outlet 33 inside the housing 21.

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

The fan 23 is provided in the ventilation passage 31. The fan 23 rotates around the rotation axis Axf extending in the X direction to send wind from the suction port 32 to the outlet 33 in the ventilation passage 31. As a result, the indoor unit 11 sucks the indoor air into the air passage 31 from the suction port 32, and blows out the air (wind) in the air passage 31 from the outlet 33. Therefore, in the present specification, the side of the ventilation passage 31 close to the suction port 32 is referred to as an upstream, and the side close to the outlet 33 is referred to as a downstream.

The fan 23 is located downstream of the heat exchanger 22. Therefore, when the fan 23 generates wind, the air sucked from the suction 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.

The filter 24 is provided in the vicinity of the suction port 32 or the suction port 32 in the ventilation passage 31. The filter 24 is located upstream of the heat exchanger 22. The filter 24 covers the suction port 32 from the inside of the housing 21. The filter 24 filters, for example, the air sucked from the suction port 32 and captures the 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 the outlet 33 or in the vicinity of the outlet 33. The wind direction plate 25 is located downstream of the fan 23. The two wind direction plates 25 are arranged side by side in the substantially Y direction along the lower surface 21b, for example.

Each of the two wind direction plates 25 is movable between the first closed position Pc1 shown in FIG. 1 and the first open position Po1 shown in FIG. 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 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 outlet 33.

As shown in FIG. 2, the wind direction plate 25 located at the first opening position Po1 opens a part of the 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 outlet 33.

The first opening position Po1 includes various positions in which the wind direction plate 25 opens a part of the 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 plate 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 the horizontal direction and a position facing downward. The wind direction plate 25 located at the first opening position Po1 adjusts the vertical direction of the wind discharged from the outlet 33 according to the direction of the wind direction plate 25. That is, as shown in FIG. 2, when the wind direction plate 25 faces in the substantially horizontal direction, the indoor unit 11 emits wind in the substantially horizontal direction. On the other hand, when the wind direction plate 25 faces downward, the indoor unit 11 emits wind downward.

The indoor unit 11 may further have a left-right wind direction plate for adjusting the direction of the wind discharged from the outlet 33 in the left-right direction. The left and right wind direction plates are provided, for example, in the ventilation passage 31. 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, for example, a synthetic resin. The wind direction plate 25 may be made of another material 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 in a substantially columnar shape extending in the X direction. The shaft portion 41 is rotatably supported by the housing 21 around a rotation shaft Axl extending in the X direction. It should be noted that each of the plurality of wind direction plates 25 has an individual rotation axis Axl. The plate portion 42 projects from the shaft portion 41 in a direction substantially orthogonal 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 around the rotation shaft Axl, the wind direction plate 25 can move 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 the wind direction plate 25A and the wind direction plate 25B. The description common to the wind direction plates 25A and 25B is described as an explanation about the wind direction plate 25.

The wind direction plate 25A is located between the upward end 33a of the outlet 33 and the downward end 33b of the outlet 33 in the Z direction. The wind direction plate 25B is located in the vicinity of the downward end 33b of the outlet 33. The wind direction plate 25A is closer to the upward end 33a of the outlet 33 than the wind direction plate 25B. The wind direction plate 25B is closer to the downward end 33b of the outlet 33 than the wind direction plate 25A.

The wind direction plates 25A and 25B located at the first opening position Po1 divide the 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 upward 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 downward 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 opening position Po1 and covers the flow path C1 at the first closing position Pc1. The wind direction plate 25B opens the flow path C2 at the first opening position Po1 and covers the flow path C2 at the first closing position Pc1.

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

Each of the two ventilation members 26 is movable between the second closed position Pc2 shown by the solid line in FIG. 2 and the second open position Po2 shown by the alternate long and short dash line in FIG. In other words, the ventilation member 26 can be arranged at the second closed position Pc2. 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 the ventilation member 26A and the ventilation member 26B. The description common to the ventilation members 26A and 26B is described as a description of the ventilation member 26.

For example, the ventilation member 26A is located in the vicinity of the upward end 33a of the outlet 33. The ventilation member 26B is located between the upward end 33a of the outlet 33 and the downward end 33b of the outlet 33 in the Z direction. The ventilation member 26A is closer to the upward end 33a of the outlet 33 than the ventilation member 26B. The ventilation member 26B is closer to the downward end 33b of the outlet 33 than the ventilation member 26A. 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 outlet 33 opened by the wind direction plate 25 located at the first open position Po1. In the present 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 at the second closed position Pc2, the two ventilation members 26 cover all the flow paths C1 and C2. The two ventilation members 26 located at the second closed position Pc2 do not need to completely close the outlet 33. For example, the outlet 33 may be communicated indoors without being covered by the ventilation member 26 in the X direction, or the wind may be able to pass through the gap between the ventilation member 26 and the wind direction plate 25. .. In the present embodiment, it is sufficient that most of the flow paths C1 and C2 are covered with the ventilation members 26A and 26B when viewed in the traveling direction of the wind. The mode in which the ventilation member 26 covers the outlet 33 is not limited to this example.

The ventilation member 26 located at the second opening position Po2 opens a part of the outlet 33 opened by the wind direction plate 25 located at the first opening position Po1. In the present 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, for example, a synthetic resin. The ventilation member 26 may be made of another material such as metal. Each of the two ventilation members 26 has a shaft portion 51 and a plate portion 52.

The shaft portion 51 is formed in a substantially columnar shape extending in the X direction. The shaft portion 51 is rotatably supported by the housing 21 around a rotation shaft Axc extending in the X direction. The plurality of ventilation members 26 each have an individual rotation axis Axc. The plate portion 52 projects from the shaft portion 51 in a direction substantially orthogonal 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 around the rotation shaft Axc, the ventilation member 26 can move between the second closed position Pc2 and the second open position Po2.

The shaft portion 51 of the ventilation member 26 is separated upward from the plate portion 42 of the wind direction plate 25 located at the first opening position Po1. The plate portion 52 of the ventilation member 26 located at 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 at the second closed position Pc2 abuts on the plate portion 42 of the wind direction plate 25 or is arranged in the vicinity of the plate portion 42. As a result, the ventilation member 26 located at the second closed position Pc2 covers a part of the outlet 33 opened by the wind direction plate 25 located at the first open position Po1. The tip 52a is an end of a plate 52 located on the opposite side of the shaft 51.

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

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. As a result, when the ventilation member 26 moves between the second closed position Pc2 and the second open position Po2, it is suppressed from interfering with the wind direction plate 25.

The plate portion 52 has an inner surface 52b and an outer surface 52c. The inner surface 52b faces the ventilation passage 31 at 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 at 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 outlet 33 opened by the wind direction plate 25 located at the first opening position Po1. .. Even if the two ventilation members 26 are located at the second opening position Po2, when the wind direction plate 25 is located at the first closing position Pc1, the flow paths C1 and C2 are covered with the corresponding wind direction plates 25. ..

As shown in FIG. 1, the ventilation member 26A located at the second opening position Po2 is housed in the recess 21c of the housing 21 provided in the vicinity of the outlet 33. The recess 21c is recessed from the inner surface 21d of the housing 21 forming a part of the ventilation passage 31. The ventilation member 26A located at the second opening position Po2 is accommodated in the recess 21c, so that it is suppressed from blocking the wind flowing through the ventilation passage 31.

The ventilation member 26B is provided in the ventilation passage 31 in the vicinity of the outlet 33. The plate portion 52 of the ventilation member 26B located at the second opening position Po2 extends in a direction along the flow of wind in the ventilation passage 31. As a result, the ventilation member 26B located at the second opening position Po2 is prevented from blocking the wind flowing through the ventilation passage 31. The arrangement of the ventilation members 26A and 26B located at the second opening position Po2 is not limited to the above example.

FIG. 3 is a front view schematically showing a part of the wind direction plate 25 and the 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 openings 55 and a plurality of second ventilation openings 56. It should be noted 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, the plurality of first ventilation openings 55 and the plurality of second ventilation openings 56 are through holes that penetrate the plate portion 52, respectively. Therefore, the plurality of first ventilation openings 55 and the plurality of second ventilation openings 56 open to the inner surface 52b and the outer surface 52c of the plate portion 52, respectively.

The plurality of first ventilation openings 55 and the plurality of second ventilation openings 56 are alternately arranged 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 the first direction, and is a direction along the outer surface 52c of the plate portion 52.

In the present embodiment, the arrangement direction Dp is substantially 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 substantially equal to the Z direction. 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 the second direction, and is a direction along the outer surface 52c of the plate portion 52 and intersecting the arrangement direction Dp. The first ventilation port 55 may be a hole having a circular, quadrangular, triangular, or other shaped cross section. The plurality of first ventilation openings 55 are arranged in the arrangement direction Dp.

The second ventilation port 56 is a hole having a circular cross section. The second ventilation port 56 may be a hole having a quadrangular shape, a triangular shape, or a cross section having another shape. In the present embodiment, the cross section of the first ventilation port 55 and the second ventilation port 56 is a cross section orthogonal 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 openings 56 are arranged in the X direction. In other words, the plurality of second ventilation openings 56 are arranged in the X direction with a distance from each other. Therefore, the plurality of second ventilation openings 56 form a row 58 of the plurality of second ventilation openings 56 arranged 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 openings 56 may be arranged in a grid pattern or may be arranged in a staggered pattern.

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

The first ventilation port 55 is arranged at both ends of the row 59 of the first ventilation port 55 and the second ventilation port 56 arranged in the arrangement direction Dp. Therefore, in the arrangement direction Dp, the plurality of second ventilation openings 56 are located between two of the plurality of first ventilation openings 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 arranged in the arrangement direction Dp. In this case, in the arrangement direction Dp, the plurality of first ventilation openings 55 are located between two of the plurality of second ventilation openings 56.

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

As shown in FIG. 4, each of the plurality of first ventilation openings 55 has an enlarged portion 61 and a straight portion 62, respectively. The enlarged portion 61 and the straight portion 62 are each a 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 of the plate portion 52 toward the outer surface 52c.

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

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 size of the cross section of the straight portion 62 is substantially equal to the size of the cross section in the smallest portion of the enlarged portion 61.

The diameter of the largest portion of the enlarged portion 61 is set to, for example, 3 to 5 mm. Further, the diameter of the minimum portion of the enlarged portion 61 and the diameter of the straight portion 62 is set to, for example, 50 to 90% of the diameter of the maximum portion of the enlarged portion 61. The size of the first ventilation port 55 is not limited to this example.

The plurality of second ventilation openings 56 also have an enlarged portion 65 and a straight portion 66, respectively. The enlarged portion 65 and the straight portion 66 are each a part of the second ventilation port 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 toward the outer surface 52c.

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

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.

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, 86, two switching motors 87, 88, and a receiver 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 housings. 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. The control device 80 is not limited to this example.

The controller 80 controls the operation of the air conditioner 10 by reading the program from the storage device and executing the program. 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 receiving device 89.

The first drive circuit 81 is a drive circuit for the fan motor 84. The fan motor 84 rotates and drives the fan 23 around the rotation shaft 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 drive the corresponding wind direction plate 25 around the rotation axis Axl, respectively. In the present embodiment, the wind direction plate motor 85 rotationally drives the wind direction plate 25A around the rotation axis Axl of the wind direction plate 25A. The wind direction plate motor 86 rotationally drives 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 of two switching motors 87 and 88. The switching motors 87 and 88 respectively drive the corresponding ventilation member 26 to rotate around the rotation axis Axc. In the present embodiment, the switching motor 87 rotationally drives the ventilation member 26A around the rotation shaft Axc of the ventilation member 26A. The switching motor 88 rotationally drives 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 radio signal such as an electromagnetic wave or an infrared ray from the remote controller 89a. The control device 80 acquires an instruction signal from the remote controller 89a from the receiving device 89.

Hereinafter, an example of the operation of the indoor unit 11 will be described. The operation of the indoor unit 11 is not limited to the following example. The indoor unit 11 of the present embodiment can be operated in the first mode and the second mode. In the first mode, the indoor unit 11 supplies a wind closer to the natural wind into the room. In the second mode, the indoor unit 11 supplies a wind that makes the user feel cold or warm into the room. The indoor unit 11 can be operated in the first mode and the second mode in both the cooling operation and the heating operation.

In the first mode, the control device 80 controls the second drive circuit 82 to arrange the wind direction plates 25A and 25B at the first opening position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation members 26A and 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 and 25B around the rotation axis Axl. As a result, the wind direction plates 25A and 25B move to the first opening position Po1 and open the outlet 33.

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

The control device 80 further controls the second drive circuit 82 and brings the wind direction plates 25A and 25B closer to the tip 52a of the plate portion 52 of the ventilation members 26A and 26B. As a result, the gap between the ventilation members 26A and 26B and the wind direction plates 25A and 25B is narrowed, and the ventilation members 26A and 26B cover most of the flow paths C1 and C2.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send wind from the suction port 32 to the outlet 33. 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 wind. You may.

The wind sent by the fan 23 passes through the ventilation passage 31 and reaches the outlet 33. The outlet 33 is covered with a ventilation member 26 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 26.

As shown in FIG. 4, a part of the wind sent by the fan 23 is discharged to the outside of the indoor unit 11 as the first wind W1 from the first ventilation port 55. The cross section of the first ventilation port 55 is set to be larger than the cross section of the second ventilation port 56. Therefore, the flow velocity of the first wind W1 becomes relatively slow. In the present 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 wind sent by the fan 23 is discharged to the outside of the indoor unit 11 as the second wind W2 from the second ventilation port 56. The cross section of the second ventilation port 56 is set smaller than the cross section of the first ventilation port 55. Therefore, the flow velocity of the second wind W2 becomes relatively high. In the present 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. 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 ejected from the second ventilation port 56. The jet stream has a high flow velocity and entrains the surrounding air to stir the air inside the jet stream. In addition, the jet stream tends to become a turbulent flow and generate a vortex.

The first ventilation port 55 and the second ventilation port 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, the first wind W1 is drawn in. As a result, the first wind W1 hits the second wind W2. Further, the second wind W2 that has transitioned to the turbulent flow diffuses 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 velocities and states (laminar flow or turbulent flow) flow adjacent to each other and hit 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.

Further, the first ventilation port 55 has an enlarged portion 61. Therefore, a part of the first wind W1 discharged from the first ventilation port 55 faces the second wind W2 discharged from the second ventilation port 56 adjacent to the first ventilation port 55. Flows. As a result, the first wind W1 is more likely to be hit by the second wind W2.

Similarly, the second ventilation port 56 has an enlarged portion 65. Therefore, a part of the second wind W2 discharged from the second ventilation port 56 faces the first wind W1 discharged from the first ventilation port 55 adjacent to the second ventilation port 56. Flows. As a result, the second wind W2 is more likely to be hit by the first wind W1.

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

Generally, the turbulent flow travels macroscopically in one direction, but microscopically, the direction of movement of the fine particles of the fluid in the turbulent flow is disordered, so that the energy loss is larger than that of the laminar flow. Therefore, the turbulent wind is easily attenuated and assimilate into the atmosphere at a shorter distance than the laminar wind and disappear. However, the turbulent flow Ws generated in the first mode is less likely to be attenuated than a simple turbulent flow because, for example, the second wind W2, which is a turbulent flow, is propelled by the first wind W1 which is a laminar flow. Therefore, the turbulent flow Ws can reach a distance farther from the indoor unit 11 than, for example, the second wind W2 that has transitioned to the 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 and 25B at the first opening position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation members 26A and 26B at the second opening position Po2.

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

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send wind from the suction port 32 to the outlet 33. The wind sent by the fan 23 passes through the ventilation passage 31 and is discharged to the outside of the indoor unit 11 from the outlet 33. Since the ventilation member 26 is located at the second opening position Po2, the wind sent by the fan 23 does not pass through the first ventilation port 55 and the second ventilation port 56, but from the outlet 33 to the indoor unit 11. It is released directly to the outside. A part of the wind 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 is more likely to feel cold or warm. For example, the wind has a high flow velocity and hits the user locally, which makes the user feel colder or warmer. On the other hand, if the wind hits the user, the user may feel uncomfortable.

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

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

In the air conditioner 10 according to the first embodiment described above, the ventilation member 26 covers at least a part of the outlet 33 opened by the wind direction plate 25 located at the first opening position Po1. It can be placed at 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. It is provided side by side in the arrangement direction Dp along the outer surface 52c. When the ventilation member 26 is arranged at the second closed position Pc2, the air sent by the fan 23 is discharged to the outside through the first ventilation port 55 and the second ventilation port 56. 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 The flow velocities are different from each other. Since the first ventilation port 55 and the second ventilation port 56 are lined up, 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 diffuse over a wide area are generated. The turbulent flow Ws is closer to the natural wind than the wind discharged from the outlet 33 without passing through the first ventilation port 55 and the second ventilation port 56. Therefore, the air conditioner 10 of the present embodiment makes the wind that hits the user closer to the natural wind, and makes it possible to reduce the discomfort of the user.

The ventilation member 26 is provided with a plurality of first ventilation openings 55 and a plurality of second ventilation openings 56. The plurality of first ventilation openings 55 and the plurality of second ventilation openings 56 are alternately arranged in the arrangement direction Dp along the outer surface 52c. As a result, the first wind W1 and the second wind W2 are likely to hit each other outside the air conditioner 10. Therefore, the air conditioner 10 tends to generate turbulent flow Ws that is closer to the natural wind.

In the arrangement direction Dp, at least one of the plurality of second ventilation openings 56 is located between two of the plurality of first ventilation openings 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 be laminar than the second wind W2. Therefore, the second wind W2 that has transitioned to the turbulent flow is located between the two first winds W1 as the laminar flow. Laminar flows have less energy loss than turbulence and are easier to reach farther. Therefore, the air conditioner 10 can propel the second wind W2 that has transitioned to the turbulent flow to the first wind W1 that is the laminar flow, and deliver the turbulent flow Ws that is close to the generated natural wind to a farther distance. Will be.

The plurality of first ventilation openings 55 extend in the X direction along the outer surface 52c and intersecting the arrangement direction Dp. The plurality of second ventilation openings 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 is more likely to become a laminar flow, and the second wind W2 is more likely to transition to a turbulent flow. Therefore, the air conditioner 10 can propel the second wind W2 that has transitioned to the turbulent flow to the first wind W1 that is the laminar flow, and deliver the turbulent flow Ws that is close to the generated natural wind to a farther distance. Will be.

At least one of the plurality of first ventilation openings 55 and the plurality of second ventilation openings 56 has enlarged portions 61 and 65 which are opened to the outer surface 52c and whose cross section expands as the outer surface 52c approaches. As a result, the wind passing through the enlarged portions 61 and 65 is likely to hit other winds passing through the first ventilation port 55 and the second ventilation port 56. Therefore, the air conditioner 10 tends to generate turbulent flow Ws that is closer to the natural wind.

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

The ventilation member 26 is between the second closed position Pc2 and the second open position Po2 that opens at least a part of the outlet 33 opened by the wind direction plate 25 located at the first open position Po1. It is movable. Therefore, the air conditioner 10 can discharge the air discharged from the 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 emitted from the 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 opening position Po1, the ventilation member 26 at the second closing position Pc2, and arranges the fan 23 from the suction port 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 that is more likely to transition to turbulence than the first wind W1 is discharged to the outside from the second ventilation port 56. Will be done. As a result, the first wind W1 and the second wind W2 hit each other outside the air conditioner 10 to generate turbulent flow Ws that diffuses over a wide area. On the other hand, in the second mode, the control device 80 arranges the wind direction plate 25 at the first opening position Po1 and the ventilation member 26 at the second opening position Po2, and arranges the ventilation member 26 at the second opening position Po2. Let the wind be sent to 33. In this case, the wind is discharged to the outside from the outlet 33 without passing through the first ventilation port 55 and the second ventilation port 56. Therefore, the air conditioner 10 is, for example, in a first mode in which a wind closer to a natural wind is emitted, or a second mode in which a wind in which a colder or warmer feeling is easily perceived is emitted, in response to a user's request, for example. It becomes possible to operate in the mode.

In the above first embodiment, the flow paths C1 and C2 are covered with the ventilation members 26A and 26B. However, either one of the flow paths C1 and C2 may be opened without being covered by the wind direction plates 25A and 25B and the ventilation members 26A and 26B. In this case, the flow velocity of the wind discharged from the opened flow path C1 or the flow path C2 passes through the first ventilation port 55 or the second ventilation port 56 of the ventilation member 26 covering the flow path C1 or the flow path C2. It is slower than the flow velocity of the wind. Therefore, the wind discharged from the opened flow path C1 or the flow path C2 is caught 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 flow path C1 or the second ventilation port 56.

The wind discharged from the opened flow path C1 or the flow path C2 and the wind passing 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. , Generates turbulence that spreads over a wide area. The turbulence is closer to the natural wind than the wind emitted from the open channel C1 or channel C2. Therefore, the air conditioner 10 makes it possible to make the wind hitting the user closer to the natural wind and reduce the discomfort of the user.

(Second embodiment)
The second embodiment will be described below with reference to FIG. In the following description of the plurality of embodiments, the components having the same functions as the components already described may be designated by the same reference numerals as those described above, and the description may be omitted. .. Further, the plurality of components with the same reference numerals do not necessarily have all the functions and properties in common, and may have different functions and properties according to each embodiment.

FIG. 8 is a cross-sectional view schematically showing an 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 the ventilation member 26A and does not have the ventilation member 26B. That is, in the second embodiment, the number of ventilation members 26 is smaller than the number of flow paths C1 and C2.

In the second embodiment, in the first mode, the control device 80 arranges the wind direction plate 25A at the first opening position Po1 by controlling the second drive circuit 82. On the other hand, the control device 80 arranges the wind direction plate 25B at the first closed position Pc1 by controlling the second drive circuit 82. As a result, the flow path C1 is opened by the wind direction plate 25A located at the first opening position Po1, and the flow path C2 is covered by the wind direction plate 25B located at the first closing 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 plate 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, of the outlet 33, the flow path C1 opened by the wind direction plate 25A located at the first opening position Po1 is covered with the ventilation member 26A. In FIG. 8, the ventilation member 26A located at the second closed position Pc2 is shown by a solid line, and the ventilation member 26A located at the second open position Po2 is shown by a two-dot chain line.

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

The flow path C2 of the outlet 33 is covered with the wind direction plate 25B. On the other hand, the flow path C1 of the outlet 33 is covered with 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 and 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 outlets 33, the flow path C2 is covered with the wind direction plate 25B, and the flow path C1 is covered with the ventilation member 26A. Thereby, even if the number of the ventilation members 26 is smaller than the number of the flow paths C1 and C2 partitioned by the wind direction plate 25, the ventilation members 26 can cover all the open flow paths 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 flow paths C1 and C2, the air conditioner 10 keeps at least one flow path C2 closed in the first mode and the remaining flow paths. 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 flow paths 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)
The third embodiment will be described below with reference to FIG. FIG. 9 is a cross-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 the wind direction plate 25C instead of the wind direction plates 25A and 25B. Further, the ventilation member 26 has a ventilation member 26C instead of the ventilation members 26A and 26B.

The wind direction plate 25C is located between the first closed position Pc1 shown by the alternate long and short dash line in FIG. 9 and the first open position Po1 shown by the solid line in FIG. 9, like the wind direction plates 25A and 25B of the first embodiment. It is possible to move with. 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 upward end 33a of the outlet 33 and the downward 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 outlet 33. Further, the wind direction plate 25C located at the first opening position Po1 opens a part of the outlet 33.

The wind direction plate 25C located at the first opening position Po1 partitions the 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 upward 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 downward end 33b of the outlet 33.

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

The ventilation member 26C is movable between the second closed position Pc2 shown by the solid line in FIG. 9 and the second open position Po2 shown by the alternate long and short dash line in FIG. In other words, the ventilation member 26C can be arranged at 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 in the vicinity of the downward end portion 33b of the outlet 33. At the second closed position Pc2, the plate portion 52 of the ventilation member 26C extends between the upward end portion 33a and the downward end portion 33b of the 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 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 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 opening 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 openings 55 and a plurality of second ventilation openings 56. The first ventilation port 55 and the second ventilation port 56 may penetrate the ventilation member 26 in the thickness direction or may penetrate 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 opening position Po1 by controlling the second drive circuit 82. In the third embodiment, the wind direction plate 25C is rotationally driven by, for example, the wind direction plate motor 85 controlled by the second drive circuit 82.

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, for example, a switching motor 87 controlled by the third drive circuit 83.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send wind from the suction port 32 to the outlet 33. The wind sent by the fan 23 passes through the ventilation passage 31 and reaches the outlet 33. The outlet 33 is covered with 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 and 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 opening position Po1. Further, the control device 80 controls the third drive circuit 83 to arrange the ventilation member 26C at the second opening position Po2. The ventilation member 26C faces in the direction of the set wind direction as the wind direction plate.

Further, the control device 80 controls the first drive circuit 81 to cause the fan 23 to send wind from the suction port 32 to the outlet 33. The wind sent by the fan 23 passes through the ventilation passage 31 and is discharged to the outside of the indoor unit 11 from the outlet 33. Since the ventilation member 26C is located at the second opening position Po2, the air sent by the fan 23 does not pass through the first ventilation port 55 and the second ventilation port 56, and is used as an indoor unit from the flow paths C3 and C4. It is released directly to the outside of 11.

In the air conditioner 10 of the third embodiment described above, one ventilation member 26C covers all the flow paths C3 and C4. As a result, the number of parts of the air conditioner 10 is reduced, and the ventilation member 26C can be easily moved from the second opening position Po2 to the second closing position Pc2.

In the above plurality of embodiments, the outlet 33 is divided into two flow paths by at least one wind direction plate 25. However, the outlet 33 may not be partitioned by the wind direction plate 25, or may be partitioned into three or more flow paths by a plurality of wind direction plates 25.

Further, in the above embodiment, the ventilation member 26 is movable between the second closed position Pc2 and the second open position Po2. However, the ventilation member 26 may be, for example, a member that can be attached to the housing 21 or the wind direction plate 25 so as to be arranged at the second closed position Pc2.
