It is possible to cover the opening. In addition, the side shielding members 20 and 90 can cover portions of the air outlet 15 other than the first portion 16 of the air outlet 15 covered by the up and down airflow direction adjusting blades 30.

  Further, the side shielding members 20 and 90 are in a state where the side shielding members 20 and 90 and the up and down wind direction adjusting blades 30 shield the air outlet 15, in other words, the wind direction state of the indoor unit 10 is in the operation stop state. In some cases, in the bottom view of the indoor unit 10, a part of the side shielding members 20 and 90 that cover the opening portion formed on the bottom surface of the indoor unit casing 12 in the outlet 15, and the vertical airflow direction adjustment blade 30. Are arranged substantially continuously in the left-right direction.

  In the following, for convenience of explanation, of the side shielding members 20, 90, the side shielding member disposed at the lower right side of the indoor unit 10 in the front view of the indoor unit 10 is referred to as the right side shielding member 20, The side shielding member disposed in the lower left portion of the indoor unit 10 is referred to as a left side shielding member 90. Further, since the right side shielding member 20 is the same as the left side shielding member 90 having a symmetrical configuration, only the configuration of the left side shielding member 90 will be described here, and the configuration of the right side shielding member 20 will be described. Description of is omitted.

  As shown in FIGS. 13, 14, and 15, the left-side shielding member 90 has a curved shape along the lower corner of the indoor unit 10. Further, the left side shielding member 90 includes a first part 91 and a second part 92. The first portion 91 includes the first end 90 a of the left side shielding member 90. Further, the second portion 92 includes the second end portion 90 b of the left side shielding member 90.

  Further, the side shielding members 20 and 90 can take two states (a closed state and an open state). In the following, for convenience of explanation, when the side shielding members 20 and 90 are closed in the air outlet 15, the portions covered by the left side shielding member 90, in other words, in the air outlet 15, the side shielding members 20 and 90 are covered. A space in which the left side shielding member 90 is disposed when the 90 is in a closed state is referred to as a second portion 17a of the outlet 15 and is a portion covered by the right side shielding member 20, in other words, the side shielding at the outlet 15. A space in which the right side shielding member 20 is disposed when the members 20 and 90 are in a closed state is referred to as a third portion 17b of the outlet 15.

  When the state of the side shielding members 20 and 90 is a closed state, the side shielding members 20 and 90 are disposed so as to cover the second portion 17a and the third portion 17b of the outlet 15 (see FIG. 13). Specifically, when the side shielding members 20 and 90 are in the closed state, the right side shielding member 20 is disposed so as to cover the third portion 17b of the air outlet 15, and the left side shielding member 90 is It arrange | positions so that the 2nd part 17a of the blower outlet 15 may be covered. For this reason, when the up-and-down wind direction adjusting blade 30 and the side shielding members 20 and 90 are in the closed state, the air outlet 15 is shielded.

  When the state of the side shielding members 20 and 90 is an open state, the side shielding members 20 and 90 are disposed so as to open the second portion 17a and the third portion 17b of the outlet 15 (see FIG. 15). . Specifically, the right side shielding member 20 is disposed so as to open the third portion 17b of the air outlet 15, and the left side shielding member 90 is disposed so as to open the second portion 17a of the air outlet 15.

<Configuration of first mechanism>
The first mechanism 50 is a mechanism for moving the vertical airflow direction adjusting blade 30 so that the first portion 16 of the outlet 15 is covered with the first portion 16 being opened. It is. Moreover, the 1st mechanism 50 can switch the state of the up-and-down air direction adjustment blade | wing 30 by moving the position of the up-and-down air direction adjustment blade | wing 30 with respect to the opening surface equivalent to the 1st part 16 in the blower outlet 15. FIG.

  Further, the first mechanism 50 includes protrusion mechanisms 51 and 61 and an angle adjustment mechanism 71.

  The urging mechanisms 51 and 61 are a first connecting portion that is a portion where the upper and lower air direction adjusting blades 30 and the urging mechanisms 51 and 61 are connected such that the upper and lower air direction adjusting blades 30 are urged out from the vicinity of the air outlet 15. 32 can be moved. Specifically, the push-out mechanisms 51 and 61 can move the first connecting portion 32 so that the first connecting portion 32 approaches or separates from the air outlet 15. That is, the push-out mechanisms 51 and 61 can move the first connecting portion 32 in a direction away from the air outlet 15.

  Further, the urging mechanisms 51 and 61 can move the position of the first connecting portion 32 relative to the first portion 16 of the air outlet 15 by moving the first connecting portion 32. For example, the push-out mechanisms 51 and 61 can move the first connecting portion 32 arranged at the position shown in FIG. 9 to the position shown in FIG. Further, for example, the push-out mechanisms 51 and 61 can move the first connecting portion 32 arranged at the position shown in FIG. 10 to the position shown in FIG. That is, the push-out mechanisms 51 and 61 can move the first connecting portion 32 from a predetermined position to a position different from the predetermined position by moving the first connecting portion 32. Further, the urging mechanisms 51 and 61 move the position of the first connecting portion 32 with respect to the first portion 16 of the air outlet 15 in a direction away from the air outlet 15, so that the vertical airflow direction adjusting blade 30 is moved at the air outlet 15. It can be slid forward from the opening surface corresponding to one portion 16. The thrusting mechanisms 51 and 61 function as a speed increasing mechanism that transmits the driving force of thrusting mechanism driving motors 54 and 64, which will be described later, to the first connecting portion 32 of the vertical airflow direction adjusting blade 30.

  Further, as shown in FIGS. 7 and 8, the ejection mechanisms 51 and 61 include a first ejection mechanism 51 and a second ejection mechanism 61. In the present embodiment, the configurations of the first ejection mechanism 51 and the second ejection mechanism 61 are the same. Therefore, only the configuration of the first ejection mechanism 51 will be described here, and the second ejection mechanism 51 will be described. Description of the mechanism 61 will be omitted by replacing the reference numerals of the 50th series attached to the components of the first ejection mechanism 51 with the 60th series.

  As shown in FIGS. 7 and 8, the first ejection mechanism 51 includes a pinion gear 52, a moving member 53, and an ejection mechanism driving motor 54.

  The pinion gear 52 is connected to a drive shaft 54a of the projection mechanism drive motor 54, and rotates when the projection mechanism drive motor 54 is driven.

  The moving member 53 has a rack 56 that meshes with the pinion gear 52 and a support shaft 57. The rack 56 is arranged from the vicinity of the one end portion 53a of the moving member 53 to the vicinity of the other end portion 53b. The support shaft 57 is a rod-shaped member, and protrudes outward from the end surface in the vicinity of the end portion 53 a of the moving member 53. Further, the support shaft 57 is inserted through the shaft support portion 32a of the up / down air direction adjusting blade 30 in parallel with the longitudinal direction of the up / down air direction adjusting blade 30, and supports the up / down air direction adjusting blade 30 to be rotatable.

  The push-out mechanism drive motor 54 is a stepping motor and has a drive shaft 54a. The drive shaft 54a is connected to the protrusion mechanism drive motor 54, and rotates when the protrusion mechanism drive motor 54 is driven. For this reason, the push-out mechanism drive motor 54 can rotate the pinion gear 52 by rotating the drive shaft 54a. In the present embodiment, the push-out mechanism driving motor 54 and the pinion gear 52 are disposed so as to face each other. Further, the push-out mechanism driving motor 54 is fixed to a mounting plate 80 described later.

  With this configuration, when the thrusting mechanism driving motors 54 and 64 rotate the pinion gears 52 and 62, power is transmitted to the racks 56 and 66 that mesh with the pinion gears 52 and 62, and the pinion gears 52 and 62 are driven. The positions of the moving members 53 and 63 change. Specifically, as shown in FIGS. 7 and 8, the ends of the moving members 53 and 63 that are connected to the up and down airflow direction adjusting blades 30 are the lower ends 53 a and 63 a of the moving members 53 and 63, and the lower ends If the ends opposite to 53a and 63a are the upper end portions 53b and 63b of the moving members 53 and 63, the upper end portions 53b and 63b of the moving members 53 and 63 are driven by driving the driving mechanism driving motors 54 and 64, respectively. 63b moves to a position near the pinion gears 52 and 62, or moves to a position away from the pinion gears 52 and 62. For this reason, the up-and-down air direction adjusting blade 30 connected to the lower end portions 53a and 63a of the moving members 53 and 63 is an opening surface corresponding to the first portion 16 in the air outlet 15 as the moving members 53 and 63 move. In the direction toward the side, i.e., the direction in which the first portion 16 of the outlet 15 is shielded, or the direction away from the opening surface corresponding to the first portion 16 in the outlet 15, i.e., the direction in which the first portion 16 of the outlet 15 is opened. To do. Thus, the protrusion mechanisms 51 and 61 can adjust the distance from the 1st part 16 of the blower outlet 15 to the 1st connection part 32. As shown in FIG.

  Accordingly, the thrusting mechanisms 51 and 61 can slide and move the vertical wind direction adjusting blades 30 so that the vertical wind direction adjusting blades 30 are pushed out from the vicinity of the outlet 15. Note that the rotation amount and the rotation direction of the protrusion mechanism driving motors 54 and 64 are controlled by the control unit 84 described later.

  The angle adjustment mechanism 71 is configured such that the vertical wind direction adjustment blade 30 and the angle adjustment mechanism 71 are connected so that the inclination angle with respect to the opening surface corresponding to the first portion 16 is adjusted at the outlet 15 of the vertical wind direction adjustment blade 30. The second connecting portion 33, which is a portion that is present, can be moved away from the air outlet 15. Further, the angle adjusting mechanism 71 moves the second connecting portion 33 with the support shafts 57 and 67 pivotally supported by the first connecting portion 32 as the rotation center, that is, the rotating shaft. The second connecting portion 33 arranged at a predetermined position can be moved to a position different from the predetermined position.

  Note that the above-described urging mechanisms 51 and 61 can move the support shafts 57 and 67 that function as the rotation shaft of the vertical airflow direction adjustment blade 30 together with the vertical airflow direction adjustment blade 30. In other words, the push-out mechanisms 51 and 61 can move the rotation axis of the vertical wind direction adjusting blade 30.

  In addition, the angle adjustment mechanism 71 functions as a speed reduction mechanism that transmits a driving force of an angle adjustment mechanism driving motor 73 described later to the second connection portion 33 of the up-and-down air direction adjustment blade 30.

  The angle adjustment mechanism 71 includes an angle adjustment mechanism drive motor 73 and a link mechanism 72.

  The angle adjustment mechanism drive motor 73 has a drive shaft 73a. The angle adjustment mechanism drive motor 73 is a stepping motor, and drives the link mechanism 72 via the drive shaft 73a.

  The link mechanism 72 has a swing lever 74 and an arm 75. One end of the swing lever 74 is connected to the drive shaft 73 a of the angle adjustment mechanism drive motor 73. The other end of the swing lever 74 is rotatably connected to one end of the arm 75.

  The arm 75 includes a support shaft 78. The support shaft 78 protrudes outward from both end surfaces near the end portion of the arm 75 opposite to the end portion connected to the swing lever 74. Further, the support shaft 78 is engaged with the shaft support portion 33a of the up / down air direction adjusting blade 30 and supports the up / down air direction adjusting blade 30 in a rotatable manner.

  For this reason, the link mechanism 72 is in a state in which the vertical airflow direction adjusting blade 30 shields the first portion 16 of the outlet 15 when the swing lever 74 is in the position shown in FIG. 9. Further, when the swing lever 74 is in the position shown in FIG. 10 or FIG. 11, the state of the up / down airflow direction adjusting blade 30 is the first open state or the second open state. Further, when the swing lever 74 is in the position shown in FIG. 12, the state of the up / down air direction adjusting blade 30 is the third open state. Thus, the angle adjustment mechanism 71 can adjust the distance from the first portion 16 of the air outlet 15 to the second connecting portion 33.

  Note that the above-described urging mechanisms 51 and 61 have the support shaft 78 as the center of rotation, that is, the rotation axis when the state of the vertical airflow direction adjusting blade 30 is switched from the first open state to the second open state. One connecting part 32 is moved. For this reason, when the state of the up / down airflow direction adjusting blade 30 is switched from the first open state to the second open state, the position of the support shaft 78 relative to the first portion 16 of the outlet 15 by the angle adjusting mechanism 71, that is, the first The position of the two connecting portions 33 is not moved.

  With such a configuration, the angle adjusting mechanism 71 can push and pull the second connecting portion 33 of the up-and-down air direction adjusting blade 30 by driving the angle adjusting mechanism driving motor 73. The rotation angle of the link mechanism 72, that is, the rotation amount and the rotation direction of the angle adjustment mechanism driving motor 73 are controlled by the control unit 84 described later.

  As described above, the vertical airflow direction adjusting blade 30 is adjusted in the distance from the first portion 16 of the air outlet 15 to the first connecting portion 32 by the urging mechanisms 51 and 61, and the first air outlet 15 is adjusted by the angle adjusting mechanism 71. By adjusting the distance from the part 16 to the 2nd connection part 33, the inclination angle with respect to the opening surface equivalent to the 1st part 16 in the blower outlet 15 is changed. Further, when the vertical airflow direction adjusting blade 30 is switched from the first open state to the second open state, the urging mechanisms 51 and 61 use the support shaft 78 pivotally supported by the second connecting portion 33 as the rotation axis. The 1st connection part 32 is moved. Further, when the vertical airflow direction adjusting blade 30 is switched from the second open state to the third open state, the angle adjusting mechanism 71 uses the support shafts 57 and 67 supported by the first connecting portion 32 as the rotation shaft. The 2nd connection part 33 is moved. For this reason, the support shaft pivotally supported by one of the first connecting portion 32 in the vicinity of the front end 30f and the second connecting portion 33 in the vicinity of the rear end 30e of the vertical airflow direction adjusting blade 30 is used as a rotation shaft. The inclination angle of the vertical airflow direction adjusting blade 30 with respect to the first portion 16 of the air outlet 15 is changed by moving the connecting portion that supports the support shaft that does not function as the rotation shaft.

  Further, the first mechanism 50 has a mounting plate 80. The attachment plate 80 is disposed above the opening surface corresponding to the first portion 16 at the air outlet 15. Further, on the upper surface of the mounting plate 80, two thrusting mechanism driving motors 54 and 64 that are driving sources of the thrusting mechanisms 51 and 61, and an angle adjustment mechanism driving motor that is a driving source of the angle adjusting mechanism 71. 73 is fixed. Specifically, the protrusion mechanism drive motors 54 and 64 are fixed in the vicinity of both ends of the mounting plate 80, respectively. Further, the angle adjustment mechanism driving motor 73 is fixed to a substantially central portion of the mounting plate 80. Thus, the protrusion mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 are housed inside the indoor unit casing 12 together with the mounting plate 80.

  Further, the attachment plate 80 is provided with moving member insertion openings 81a and 81b through which the respective moving members 53 and 63 can be inserted in the vicinity of the protrusion mechanism driving motors 54 and 64. The moving member insertion openings 81a and 81b are formed so that a part thereof is narrow so that the moving members 53 and 63 can support the portions other than the racks 56 and 66. Further, as shown in FIGS. 7 and 8, the attachment plate 80 is provided with guide grooves 82 a and 82 b for guiding the moving members 53 and 63.

  In addition, a lever insertion opening 83 into which the swing lever 74 can be inserted is formed in the mounting plate 80 in the vicinity of the angle adjustment mechanism driving motor 73.

  In this embodiment, the thrusting mechanisms 51 and 61 are speed increasing mechanisms, and the angle adjusting mechanism 71 is a speed reducing mechanism, so that the two thrusting mechanism driving motors 54 and 64 and the angle adjusting mechanism driving motor 73 are used. It is possible to adjust the required driving torque and the non-energizing static torque. Therefore, for example, even when the position of the vertical airflow direction adjusting blade 30 is manually moved, the torque acting on the thrusting mechanism driving motors 54 and 64 and the angle adjusting mechanism driving motor 73 can be brought close to each other. A stepping motor can be employed.

FIG. 16A is a cross-sectional view of the indoor unit 10 in which the up / down airflow direction adjusting blade 30 is in the second open state and the side shielding members 20 and 90 are in the closed state, and the outline in the vicinity of the left side shielding member 90 is illustrated. FIG. FIG. 16B is a cross-sectional view of the indoor unit 10 in which the up / down airflow direction adjusting blade 30 is in the second open state and the side shielding members 20 and 90 are in the open state, and the outline in the vicinity of the left side shielding member 90 is illustrated. FIG.

  The second mechanisms 29 and 99 are moving mechanisms different from the first mechanism 50, and the second portion 17 a of the air outlet 15 from the state where the second portion 17 a and the third portion 17 b of the air outlet 15 are shielded. And it is a mechanism which can move the side shielding members 20 and 90 so that the 3rd part 17b may be in the open state.

Have. Further, the right-side shielding member moving mechanism 29 is the same as the left-side shielding member moving mechanism 99 having a symmetrical configuration, and therefore, only the configuration of the left-side shielding member moving mechanism 99 will be described here. The description of the configuration of the direction shielding member moving mechanism 29 is omitted.

  The second mechanism drive motor 94 is disposed in the indoor unit body 11 and is fixed to the indoor unit casing 12. The second mechanism driving motor 94 has a rotating shaft (not shown). The rotating shaft extends in the front-rear direction of the indoor unit 10 and rotates when the second mechanism driving motor 94 is driven.

  As shown in FIG. 16, the support member 93 is a plate-like member, and one end portion 93 a thereof is connected to the vicinity of the first end portion 90 a of the left side shielding member 90. The other end portion 93b of the support member 93 is connected to a rotation shaft, and the support member 93 moves in the rotation direction around the rotation shaft as the rotation shaft rotates.

  With such a configuration, in the second mechanisms 29 and 99, the rotation shaft rotates when the second mechanism driving motors 24 and 94 are driven, and the support member moves in the rotation direction when the rotation shaft rotates. Further, as the support member moves in the rotation direction, the side shielding members 20 and 90 move in the rotation direction about the rotation axis. For this reason, the side shielding members 20, 90 can shield or open the second portion 17a and the third portion 17b of the outlet 15 by moving so as to draw an arc. The driving of the second mechanism driving motors 24 and 94 is controlled by a control unit 84 to be described later.

The accommodating part 25 is arrange | positioned in the 3rd part 17b vicinity of the blower outlet 15 in the blowing flow path. The storage unit 95 is disposed in the vicinity of the second portion 17a of the outlet 15 in the outlet channel. For this reason, the blowout flow path is divided into three flow paths by the storage portions 25 and 95 at the lower part thereof. Here, for convenience of explanation, the outlet of the outlet channel is defined by the upper ends of the two storage portions 25 and 95, and the outlet of the outlet channel is the first part 16 of the outlet 15. It is called channel B. Further, in the blowing channel, the channel portion in which the upper end portion of the storage portion 25 is located at the inlet and the outlet is the third portion 17b of the outlet 15 is referred to as the right blowing channel D. Further, in the blowout flow path, the flow path portion in which the upper end portion of the storage portion 95 is located at the inlet and the outlet thereof is the second portion 17a of the blowout opening 15 is referred to as the left blowout flow path C. That is, the storage unit 25 is disposed between the main blowing channel B and the right blowing channel D, and the storing unit 95 is disposed between the main blowing channel B and the left blowing channel C. Yes. Further, the outlets of the blowout flow paths are closed by the up / down air direction adjusting blades 30, the left side shielding member 90, and the right side shielding member 20, respectively. Specifically, the outlet of the main blowing channel B is blocked by the up / down airflow direction adjusting blade 30, the outlet of the left blowing channel C is blocked by the left side shielding member 90, and the right side blowing member 20 is blocked by the right side shielding member 20. The exit of road D is blocked.

  The storage portions 25 and 95 have first wall portions 26 and 96 and second wall portions 27 and 97 that form a storage space in which the side shielding members 20 and 90 in the open state are stored. . The first wall portions 26, 96 extend upward from the vicinity of the second portion 17 a or the vicinity of the third portion 17 b of the air outlet 15. Moreover, the 1st wall parts 26 and 96 are exhibiting the curved shape so that it could respond to the side shielding members 20 and 90, and the upper end part (96a; refer FIG. 16) of the 1st wall parts 26 and 96 is shown. The first wall portions 26 and 96 are disposed so as to be inclined closer to the center side of the indoor unit body 11 than the lower end portions (96b; see FIG. 16) of the first wall portions 26 and 96.

  The second wall portions 27 and 97 are located near the boundary between the first portion 16 of the outlet 15 and the second portion 17a of the outlet 15 or the third portion 16 of the outlet 15 and the third portion of the outlet 15. It extends upward from the vicinity of the boundary with the portion 17b. Moreover, the 2nd wall parts 27 and 97 are exhibiting the curved shape so that it could respond to the side shielding members 20 and 90, and the upper end part (97a; refer FIG. 16) of the 2nd wall parts 27 and 97 is shown. The second wall portions 27 and 97 are disposed so as to be inclined closer to the center side of the indoor unit body 11 than the lower end portions (97b; see FIG. 16). Furthermore, the upper end portions of the storage portions 25 and 95, that is, the upper end portions (97a; see FIG. 16) of the second wall portions 27 and 97 and the upper end portions (96a; see FIG. 16) of the first wall portions 26 and 96 are defined. It has a continuous configuration.

  Note that the vertical blades 19 are arranged in the vicinity of the indoor fan 14 rather than the upper ends of the storage portions 25 and 95 in the blowout flow path. In addition, the storage portions 25 and 95 store the tip portions of the blades of the side vertical blade portions 19d and 19e when the blades of the side vertical blade portions 19d and 19e swing and incline. It arrange | positions so that it may be located in the upper end part of the parts 25 and 95 (refer FIG. 4). For this reason, in the state where the vertical blades 19 are as shown in FIG. 4, when an air flow is generated by the indoor fan 14, conditioned air is guided to the left blowing channel C and the right blowing channel D.

  Further, when the side shielding members 20 and 90 are in the open state, the side shielding members 20 and 90 are housed in the housing space, so that the second portion 17a of the air outlet 15 and the third portion of the air outlet 15 are provided. It does not affect the air flow blown out from 17b. Therefore, the conditioned air guided to the respective inlets of the left blowing channel C and the right blowing channel D by the vertical blades 19 is guided by the first wall portions 26 and 96 inclined toward the left side or the right side. (96c; see FIG. 16), in other words, regulated by the guide surfaces of the first wall portions 26, 96, flowing through the left blowing channel C and the right blowing channel D, and the left blowing channel C and It blows out from each exit of the right blowing flow path D. In addition, since the outlets of the left outlet channel C and the right outlet channel D are open toward the side of the indoor unit 10, the outlets of the left outlet channel C and the right outlet channel D are blown out. The air flows toward the left and right sides of the indoor unit 10.

In addition, in the wind direction setting command in this embodiment, the 1st command which is a command for setting the blowing direction of air so that conditioned air blows out to the side of the indoor unit 10, and the conditioned air is mainly used for the indoor unit 10. And a second command that is a command for setting the blowing direction of air so as to blow out upward and laterally.

  The control unit 84 includes a drive control unit 85 for switching the state of the up / down airflow direction adjusting blade 30 and the side shielding members 20 and 90. The drive control unit 85 can drive the protrusion mechanisms 51 and 61 and the angle adjustment mechanism 71 at an arbitrary timing. Specifically, the drive control unit 85 controls the rotation speed and the rotation direction of the two projection mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 to thereby change the state of the vertical airflow direction adjustment blade 30. Switch. Further, the drive control unit 85 switches the state of the side shielding members 20 and 90 by controlling the rotation speed and rotation direction of the two second mechanism drive motors 24 and 94. Further, the drive control unit 85 controls only the two projection mechanism driving motors 54 and 64 to drive only the projection mechanisms 51 and 61, and corresponds to a first projection mode. An angle adjustment mechanism drive mode (corresponding to the second drive mode) in which only the angle adjustment mechanism 71 is driven by controlling only the angle adjustment mechanism drive motor 73, the two protrusion mechanism drive motors 54 and 64, and the angle adjustment. By simultaneously controlling the mechanism driving motor 73, it is possible to execute the simultaneous drive mode in which the thrusting mechanisms 51 and 61 and the angle adjusting mechanism 71 are simultaneously driven. For this reason, the control part 84 can change the wind direction state of the indoor unit 10 according to each operation mode or the wind direction setting command from the air conditioning subject. Moreover, in this embodiment, the indoor unit 10 may take six wind direction states of the operation stop state, the first cooling state, the second cooling state, the first heating state, the second heating state, and the three-way wind direction state. Is possible.

  In addition, when the wind direction state of the indoor unit 10 is an operation stop state, the up-and-down wind direction adjusting blades 30 and the side shielding members 20 and 90 are all closed. Moreover, when the wind direction state of the indoor unit 10 is the 1st cooling state, the up-and-down wind direction adjustment blade 30 has taken the 2nd open state, and the side shielding members 20 and 90 have taken the closed state. When the wind direction state of the indoor unit 10 is the second cooling state, the vertical wind direction adjusting blade 30 is in the second open state, and the side shielding members 20 and 90 are in the open state. When the wind direction state of the indoor unit 10 is the first heating state, the vertical wind direction adjusting blades 30 are in the third open state, and the side shielding members 20 and 90 are in the closed state. When the wind direction state of the indoor unit 10 is the second heating state, the up / down wind direction adjusting blades 30 are in the third open state, and the side shielding members 20 and 90 are in the open state. When the wind direction of the indoor unit 10 is the three-way wind direction, the vertical wind direction adjusting blade 30 is in the first open state, and the side shielding members 20 and 90 are in the open state.

  For example, when the operation of the air conditioner 1 is stopped, that is, when the wind direction of the indoor unit 10 is the operation stop state, a cooling operation start command is issued from the air conditioning target person via the remote controller 86. Then, the drive control part 85 controls the 1st mechanism 50 so that the wind direction state of the indoor unit 10 may turn into a 1st cooling air direction state. Specifically, the drive control unit 85 executes the simultaneous drive mode. More specifically, the drive control unit 85 controls the thrust mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 simultaneously to change the state of the vertical airflow direction adjustment blade 30 from the closed state to the first open state. Switch to state. And if the state of the up-and-down air direction adjustment blade | wing 30 switches to a 1st open state, the drive control part 85 will perform the squeeze mechanism drive mode. Specifically, the drive control unit 85 switches the state of the up / down airflow direction adjusting blade 30 from the first open state to the second open state by controlling the thrust mechanism drive motors 54 and 64. At this time, since the drive control unit 85 does not control to drive the second mechanism drive motors 24 and 94, the side shielding members 20 and 90 have the second portion 17 a and the third portion 17 b of the outlet 15. It arrange | positions so that it may cover, and the state where the 2nd part 17a and the 3rd part 17b of the blower outlet 15 were shielded is maintained. For this reason, only the 1st part 16 of the blower outlet 15 is open | released.

  At this time, the control unit 84 controls the drive motor so that the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Therefore, the conditioned air is guided only to the main blowing channel B by the vertical blades 19 and is not led to the left blowing channel C and the right blowing channel D.

  For this reason, when the operation of the air conditioner 1 is stopped and an air flow target is issued from the air conditioning subject via the remote controller 86 and an air flow is generated by the indoor fan 14, Air flows through the main blowout flow path B and reaches the first portion 16 of the blowout port 15. And the conditioned air which reached the 1st part 16 of the blower outlet 15 is blown off to the front side lower part of the indoor unit 10 along the inner surface 30a of the up-and-down airflow direction adjustment blade 30 (refer FIG. 14).

  As a result, the blowing direction of the air blown out from the blowout port 15 is the front lower side of the indoor unit 10, so that the indoor space in which the indoor unit 10 is installed is the first space that is the space on the front side of the indoor unit 10 and the first space. When divided into the second space, which is a space behind the one space, the conditioned air is blown mainly to the lower part of the first space in the indoor space.

  Further, when the air conditioner 1 is performing a cooling operation in which the air direction of the indoor unit 10 is the first cooling state, the first command of the air direction setting commands is sent from the air conditioning target person via the remote controller 86. If it does, the drive control part 85 will control the 2nd mechanisms 29 and 99 so that the wind direction state of the indoor unit 10 may change from a 1st cooling state to a 2nd cooling air direction state. Specifically, the drive control unit 85 controls the second mechanism drive motors 24 and 94 so that the state of the side shielding members 20 and 90 is switched from the closed state to the open state. At this time, the state of the up / down airflow direction adjusting blade 30 is maintained in the second open state. For this reason, the 1st part 16, the 2nd part 17a, and the 3rd part 17b of the blower outlet 15 are open | released.

  At this time, the control unit 84 controls the drive motor so that the main vertical blade portion 19 c of the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Further, the control unit 84 is arranged so that the tip of the left vertical blade 19d is positioned near the upper end of the storage unit 95 and the tip of the right vertical blade 19e is positioned near the upper end of the storage 25. Control the drive motor. Therefore, the conditioned air is guided to the main blowing channel B, the left blowing channel C, and the right blowing channel D by the vertical blades 19. Therefore, the conditioned air flowing through the main blowing channel B reaches the first portion 16 of the outlet 15, and the conditioned air flowing through the left outlet channel C reaches the second portion 17 a of the outlet 15 and flows through the right outlet channel D. The flowing conditioned air reaches the third portion 17b of the outlet 15 (see FIG. 15).

  And the conditioned air which reached the 1st part 16 of the blower outlet 15 blows off toward the front side lower side of the indoor unit 10 along the inner surface 30a of the up-and-down wind direction adjustment blade 30 which is inclined.

  In addition, the conditioned air flowing through the left blowing channel C is directed to the left side of the indoor unit 10 from the second portion 17a of the outlet 15 opened along the guide surface 96c of the first wall 96 of the storage unit 95. And blown out. Furthermore, the conditioned air flowing through the right outlet channel D flows from the third portion 17b of the outlet 15 opened along the guide surface of the first wall portion 26 of the storage unit 25 toward the right side of the indoor unit 10. Blown out.

  Therefore, when the air conditioner 1 is performing the cooling operation, the air blown from the air outlet 15 when the first command of the air direction setting command is issued from the air conditioning subject via the remote controller 86. Are changed to the front lower side of the indoor unit 10 and the left and right sides.

  Thereby, the blowing direction of the air blown out from the blower outlet 15 is the front lower side of the indoor unit 10 and both the left and right sides, so that the space on both sides of the indoor unit 10 in the second space is particularly a side part. In the indoor space, the conditioned air is blown mainly to the lower part of the first space and the side part of the second space.

  Further, when the air conditioner 1 is performing a cooling operation in which the airflow state of the indoor unit 10 is the first cooling state, the second command of the airflow direction setting command is received from the air conditioning target person via the remote controller 86. If it does, the drive control part 85 will control the 1st mechanism 50 and the 2nd mechanisms 29 and 99 so that the wind direction state of the indoor unit 10 may change from a 1st cooling state to a three-way wind direction state. Specifically, the drive control unit 85 executes the ejection mechanism drive mode. More specifically, the drive control unit 85 controls the thrust mechanism drive motors 54 and 64 to switch the state of the vertical airflow direction adjusting blade 30 from the second open state to the first open state. At this time, the drive control unit 85 controls the second mechanism drive motors 24 and 94 to switch the state of the side shielding members 20 and 90 from the closed state to the open state. For this reason, the 1st part 16, the 2nd part 17a, and the 3rd part 17b of the blower outlet 15 are open | released.

  At this time, the control unit 84 controls the drive motor so that the main vertical blade portion 19 c of the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Further, the control unit 84 is arranged so that the tip of the left vertical blade 19d is positioned near the upper end of the storage unit 95 and the tip of the right vertical blade 19e is positioned near the upper end of the storage 25. Control the drive motor. Therefore, the conditioned air is guided to the main blowing channel B, the left blowing channel C, and the right blowing channel D by the vertical blades 19. Therefore, the conditioned air flowing through the main blowing channel B reaches the first portion 16 of the outlet 15, and the conditioned air flowing through the left outlet channel C reaches the second portion 17 a of the outlet 15 and flows through the right outlet channel D. The flowing conditioned air reaches the third portion 17 b of the outlet 15.

  And the conditioned air which reached the 1st part 16 of the blower outlet 15 is arrange | positioned so that it may become substantially parallel to the opening surface equivalent to the 1st part 16 in the blower outlet 15, The inner surface 30a of the up-and-down air direction adjustment blade | wing 30 Along the front side of the indoor unit 10.

  In addition, the conditioned air flowing through the left blowing channel C is directed to the left side of the indoor unit 10 from the second portion 17a of the outlet 15 opened along the guide surface 96c of the first wall 96 of the storage unit 95. And blown out. Furthermore, the conditioned air flowing through the right outlet channel D flows from the third portion 17b of the outlet 15 opened along the guide surface of the first wall portion 26 of the storage unit 25 toward the right side of the indoor unit 10. Blown out.

  Therefore, when the air conditioner 1 is performing the cooling operation and the second command of the air direction setting command is issued from the air conditioning subject via the remote controller 86, the air blown out from the outlet 15 Is changed to the front upper side of the indoor unit 10 and both the left and right sides.

  As a result, the blowing direction of the air blown out from the blower outlet 15 is the front upper side and the left and right sides of the indoor unit 10, so that the conditioned air is mainly the upper part of the first space and the second space in the indoor space. It will be blown out to the side part.

  Further, for example, when a heating operation start command is issued via the remote controller 86 from the air-conditioning subject while the operation of the air conditioner 1 is stopped, the drive control unit 85 causes the air direction of the indoor unit 10 to The first mechanism 50 is controlled so that the state becomes the first heating air direction state. Specifically, the drive control unit 85 executes the simultaneous drive mode. More specifically, the drive control unit 85 controls the thrust mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 simultaneously to change the state of the vertical airflow direction adjustment blade 30 from the closed state to the first open state. Switch to state. Next, when the state of the up-and-down air direction adjusting blade 30 is switched to the first open state, the drive control unit 85 executes the push-out mechanism drive mode. Specifically, the drive control unit 85 further controls the urging mechanism drive motors 54 and 64 to switch the state of the vertical airflow direction adjusting blade 30 from the first open state to the second open state. And if the state of the up-and-down wind direction adjustment blade | wing 30 switches to a 2nd open state, the drive control part 85 will perform an angle adjustment mechanism drive mode. Specifically, the drive control unit 85 further controls the angle adjustment mechanism drive motor 73 to switch the state of the vertical airflow direction adjustment blade 30 from the second open state to the third open state. At this time, since the drive control unit 85 does not control to drive the second mechanism drive motors 24 and 94, the side shielding members 20 and 90 have the second portion 17 a and the third portion 17 b of the outlet 15. It arrange | positions so that it may cover, and the state where the 2nd part 17a and the 3rd part 17b of the blower outlet 15 were shielded is maintained. For this reason, only the 1st part 16 of the blower outlet 15 is open | released.

  At this time, the control unit 84 controls the drive motor so that the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Therefore, the conditioned air is guided only to the main blowing channel B by the vertical blades 19 and is not led to the left blowing channel C and the right blowing channel D.

  For this reason, when the operation of the air conditioner 1 is stopped and an air flow target is issued from the air conditioning subject via the remote controller 86 and an air flow is generated by the indoor fan 14, Air flows through the main blowout flow path B and reaches the first portion 16 of the blowout port 15. And the conditioned air which reached the 1st part 16 of the blower outlet 15 is blown out below the indoor unit 10 along the inner surface 30a of the up-and-down wind direction adjustment blade 30 which is inclined.

  Thereby, since the blowing direction of the air blown out from the blower outlet 15 is below the indoor unit 10, when the space below the indoor unit 10 in the second space is particularly the lower part, the conditioned air is Of these, the air is mainly blown out to the lower part of the second space.

  Further, when the air conditioner is performing a heating operation when the air direction of the indoor unit 10 is the first heating state, the first air direction setting command from the air-conditioning subject via the remote controller 86 is executed. When the command is issued, the drive control unit 85 controls the second mechanisms 29 and 99 so that the air direction state of the indoor unit 10 is changed from the first heating state to the second heating air direction state. Specifically, the drive control unit 85 controls the second mechanism drive motors 24 and 94 so that the state of the side shielding members 20 and 90 is switched from the closed state to the open state. At this time, the state of the up / down airflow direction adjusting blade 30 is maintained in the third open state. For this reason, the 1st part 16, the 2nd part 17a, and the 3rd part 17b of the blower outlet 15 are open | released.

  At this time, the control unit 84 controls the drive motor so that the main vertical blade portion 19 c of the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Further, the control unit 84 is arranged so that the tip of the left vertical blade 19d is positioned near the upper end of the storage unit 95 and the tip of the right vertical blade 19e is positioned near the upper end of the storage 25. Control the drive motor. Therefore, the conditioned air is guided to the main blowing channel B, the left blowing channel C, and the right blowing channel D by the vertical blades 19. Therefore, the conditioned air flowing through the main blowing channel B reaches the first portion 16 of the outlet 15, and the conditioned air flowing through the left outlet channel C reaches the second portion 17 a of the outlet 15 and flows through the right outlet channel D. The flowing conditioned air reaches the third portion 17 b of the outlet 15.

  And the conditioned air which reached the 1st part 16 of the blower outlet 15 blows off toward the downward direction of the indoor unit 10 along the inner surface 30a of the up-and-down wind direction adjustment blade 30 which is inclined.

  In addition, the conditioned air flowing through the left blowing channel C is directed to the left side of the indoor unit 10 from the second portion 17a of the outlet 15 opened along the guide surface 96c of the first wall 96 of the storage unit 95. And blown out. Furthermore, the conditioned air flowing through the right outlet channel D flows from the third portion 17b of the outlet 15 opened along the guide surface of the first wall portion 26 of the storage unit 25 toward the right side of the indoor unit 10. Blown out.

  Therefore, when the air conditioner 1 is performing the heating operation, if the first command of the wind direction setting command is issued from the air conditioning target person via the remote controller 86, the air blown out from the outlet 15 Is changed to the lower side of the indoor unit 10 and both the left and right sides.

  Thereby, since the blowing direction of the air blown out from the blower outlet 15 is the lower side of the indoor unit 10 and both the left and right sides, the conditioned air mainly includes the lower part and the side part of the second space in the indoor space. Will be blown out.

  Further, in the air conditioner 1, when the heating operation in the case where the wind direction state of the indoor unit 10 is the first heating state is being executed, the second of the wind direction setting commands from the air conditioning subject via the remote controller 86. When the command is issued, the drive control unit 85 controls the first mechanism 50 and the second mechanisms 29 and 99 so that the wind direction state of the indoor unit 10 changes from the first heating state to the three-way wind direction state. Specifically, the drive control unit 85 first executes an angle adjustment mechanism drive mode. More specifically, the drive control unit 85 controls the angle adjustment mechanism drive motor 73 to switch the state of the vertical airflow direction adjustment blade 30 from the third open state to the second open state. Next, the drive control unit 85 executes the ejection mechanism drive mode. Specifically, the state of the up-and-down air direction adjusting blade 30 is switched from the second open state to the first open state by controlling the protrusion mechanism driving motors 54 and 64. In this way, the drive control unit 85 switches the state of the up / down airflow direction adjusting blade 30 from the third open state to the first open state. At this time, the drive control unit 85 controls the second mechanism drive motors 24 and 94 to switch the state of the side shielding members 20 and 90 from the closed state to the open state. For this reason, the 1st part 16, the 2nd part 17a, and the 3rd part 17b of the blower outlet 15 are open | released.

  At this time, the control unit 84 controls the drive motor so that the main vertical blade portion 19 c of the vertical blade 19 stops in a state perpendicular to the longitudinal direction of the indoor unit casing 12. Further, the control unit 84 is arranged so that the tip of the left vertical blade 19d is positioned near the upper end of the storage unit 95 and the tip of the right vertical blade 19e is positioned near the upper end of the storage 25. Control the drive motor. Therefore, the conditioned air is guided to the main blowing channel B, the left blowing channel C, and the right blowing channel D by the vertical blades 19. Therefore, the conditioned air flowing through the main blowing channel B reaches the first portion 16 of the outlet 15, and the conditioned air flowing through the left outlet channel C reaches the second portion 17 a of the outlet 15 and flows through the right outlet channel D. The flowing conditioned air reaches the third portion 17 b of the outlet 15.

  And the conditioned air which reached the 1st part 16 of the blower outlet 15 is arrange | positioned so that it may become substantially parallel to the opening surface equivalent to the 1st part 16 in the blower outlet 15, The inner surface 30a of the up-and-down air direction adjustment blade | wing 30 Along the front side of the indoor unit 10.

  In addition, the conditioned air flowing through the left blowing channel C is directed to the left side of the indoor unit 10 from the second portion 17a of the outlet 15 opened along the guide surface 96c of the first wall 96 of the storage unit 95. And blown out. Furthermore, the conditioned air flowing through the right outlet channel D flows from the third portion 17b of the outlet 15 opened along the guide surface of the first wall portion 26 of the storage unit 25 toward the right side of the indoor unit 10. Blown out.

  Therefore, when the air conditioner 1 is performing the heating operation and the second command of the air direction setting command is issued from the air conditioning subject via the remote controller 86, the air blown out from the outlet 15 Is changed to the front upper side of the indoor unit 10 and both the left and right sides.

  As a result, the blowing direction of the air blown out from the blower outlet 15 is the front upper side and the left and right sides of the indoor unit 10, so that the conditioned air is mainly the upper part of the first space and the second space in the indoor space. It will be blown out to the side part.

  Further, when an operation stop command is issued from the air conditioning subject via the remote controller 86 while the air conditioner 1 is performing the heating operation or the cooling operation, the drive control unit 85 causes the air direction of the indoor unit 10 to be increased. The first mechanism 50 and / or the second mechanisms 29 and 99 are controlled so that the state becomes the operation stop state. Specifically, the drive control unit 85 executes the simultaneous drive mode when the state of the up / down airflow direction adjusting blade 30 is the first open state. More specifically, the drive control unit 85 closes the state of the up / down airflow direction adjusting blade 30 from the first open state by simultaneously driving the protrusion mechanism driving motors 54 and 64 and the angle adjusting mechanism driving motor 73. Switch to state. In addition, when the state of the up / down airflow direction adjusting blade 30 is in the second open state, the drive control unit 85 executes the simultaneous drive mode after executing the push-out mechanism drive mode. More specifically, the drive control unit 85 drives the projection mechanism drive motors 54 and 64 to switch the state of the vertical airflow direction adjusting blade 30 from the second open state to the first open state, and then performs the projection. By simultaneously driving the mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73, the state of the vertical airflow direction adjusting blade 30 is switched from the first open state to the closed state. Further, when the state of the up / down airflow direction adjusting blade 30 is in the third open state, the drive control unit 85 executes the angle adjustment mechanism drive mode, then executes the thrusting mechanism drive mode, and further performs the simultaneous drive mode. Execute. More specifically, the drive control unit 85 first drives the angle adjustment mechanism driving motor 73 to switch the state of the up / down airflow direction adjusting blade 30 from the third open state to the second open state, and then pushes out. By driving the mechanism drive motors 54 and 64, the state of the up-and-down air direction adjusting blade 30 is switched from the second open state to the first open state. Further, the projecting mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor By driving 73 at the same time, the state of the vertical airflow direction adjusting blade 30 is switched from the first open state to the closed state. In this manner, the drive control unit 85 drives the protrusion mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 to change the state of the vertical airflow direction adjusting blade 30 to the first open state and the second open state. The state or the third open state is switched to the closed state.

  Further, when an operation stop command is issued from the air conditioning target person via the remote controller 86, if the side shielding members 20 and 90 are in the open state, the drive control unit 85 includes the side shielding members 20 and 90. The second mechanism driving motors 24 and 94 are controlled so that the state 90 is switched from the open state to the closed state. For this reason, the up-and-down airflow direction adjustment blade 30 is arranged at the first portion 16 of the outlet 15, and the side shielding members 20, 90 are arranged at the second portion 17a and the third portion 17b of the outlet 15, that is, The blower outlet 15 is shielded.

  Thus, in this embodiment, various blowing directions can be taken by the up-and-down air direction adjusting blade 30 and the side shielding members 20 and 90 that are movable independently of the up-and-down air direction adjusting blade 30. In the present embodiment, the wind direction state that can be taken by the indoor unit 10 is defined as an operation stop state, a first cooling state, a second cooling state, a first heating state, a second heating state, and a three-way wind direction state. However, the present invention is not limited to this, and the indoor unit 10 may take other wind direction states depending on the combination of the state of the vertical wind direction adjusting blade 30 and the state of the side shielding members 20 and 90.

In the above embodiment, the first connecting portion 32 is disposed in the vicinity of both end portions 30 g and 30 h of the up and down airflow direction adjusting blade 30. For this reason, the support shafts 57 and 67 that function as the rotation shaft of the vertical wind direction adjusting blade 30 can be supported at both end portions 30 g and 30 h of the vertical wind direction adjusting blade 30.

In the above embodiment, the drive control unit 85 drives the protrusion mechanisms 51 and 61 and the angle adjustment mechanism 71 at an arbitrary timing. Further, the drive control unit 85 can execute a protrusion mechanism drive mode in which only the protrusion mechanisms 51 and 61 are driven and an angle adjustment mechanism drive mode in which only the angle adjustment mechanism 71 is driven. Therefore, at least one of the projecting mechanisms 51 and 61 and the angle adjusting mechanism 71 can be driven.

(11)
In the above embodiment, the first ejection mechanism 51 has the ejection mechanism driving motor 54, and the second ejection mechanism 61 has the ejection mechanism driving motor 64. That is, each of the protrusion mechanisms 51 and 61 has an independent protrusion mechanism driving motor 54 and 64, respectively. Therefore, there is no need to provide a space for connecting rods and bearings for connecting the pinion gears 52 and 62 of the respective thrusting mechanisms 51 and 61, and a stepping motor having a low torque and a small size can be employed. Yes.

In the above-described embodiment, the vertical airflow direction adjusting blade 30 is supported at three points of the two first connecting portions 32 and the second connecting portion 33. The two first connecting portions 32 are disposed in the vicinity of both end portions 30 g and 30 h of the up / down air direction adjusting blade 30, and the second connecting portion 33 is disposed in the vicinity of the approximate center of the up / down air direction adjusting blade 30. For this reason, for example, compared with the case where two 1st connection parts and 2nd connection parts are arrange | positioned in the approximate center vicinity of an up-and-down air direction adjustment blade | wing, the area of the surface containing 3 points | pieces which support the up-and-down air direction adjustment blade | wing 30 Can be enlarged. Therefore, the posture of the up / down air direction adjusting blade 30 can be stably maintained.

<Modification>
(A)
In the above embodiment, the first ejection mechanism 51 has the ejection mechanism driving motor 54, and the second ejection mechanism 61 has the ejection mechanism driving motor 64. Further, the two thrusting mechanisms 51 and 61 move the vertical wind direction adjusting blades 30 by driving the thrusting mechanism driving motors 54 and 64, respectively. In other words, one push-out mechanism is driven by one motor.

  Alternatively, the two ejection mechanisms may be driven by one motor.

  For example, when only one of the two projecting mechanisms is provided with a motor for driving the projecting mechanism and the pinion gears included in each projecting mechanism are connected by a connecting rod, the projecting mechanism The rotation of the drive motor is transmitted not only to the pinion gear connected to the drive shaft of the drive mechanism drive motor but also to the other pinion gear by the connecting rod. Moreover, each moving member is moved by rotating each pinion gear, and the position of the up-and-down air direction adjusting blade can be moved with the movement of each moving member.

  In this way, the number of motors can be reduced by driving the two thrusting mechanisms with one thrusting mechanism driving motor.

  As a result, the number of parts can be reduced, so that low cost can be realized. Further, since the pinion gears are connected by the connecting rod, the other pinion gear can be rotated in synchronization with the rotation of one pinion gear. Therefore, even when the position of the vertical airflow direction adjusting blade is manually moved, each moving member can be easily moved in parallel.

In the said embodiment, the 1st mechanism 50 of this invention is employ | adopted as the wall-hanging type indoor unit 10 attached to the indoor wall surface. Instead, the first mechanism may be employed in a ceiling-embedded indoor unit in which the indoor unit is disposed so as to be embedded in the ceiling.

(C)
In the above-described embodiment, the indoor unit 10 includes one angle adjustment mechanism 71 and two protrusion mechanisms 51 and 61.

  Instead, the indoor unit may include one angle adjustment mechanism and one protrusion mechanism, or may include one angle adjustment mechanism and three or more protrusion mechanisms.

  For example, in the case of an indoor unit including one angle adjusting mechanism and one thrusting mechanism, a connecting portion for coupling the angle adjusting mechanism and the vertical wind direction adjusting blade and the thrusting mechanism and the vertical wind direction adjusting blade are provided. The connecting portions for connection may be provided in a shape that is long in the longitudinal direction of the up / down airflow direction adjusting blades, and the respective connecting portions may be arranged in parallel near the front end portion and the rear end portion of the up / down airflow direction adjusting blade. By adopting such a configuration of the connecting portion, the inclination angle of the vertical airflow direction adjusting blade with respect to the outlet can be changed even with one angle adjusting mechanism and one projecting mechanism.

  Further, for example, in the case of an indoor unit including one angle adjustment mechanism and three protrusion mechanisms, each connection portion with each protrusion mechanism includes the vicinity of both ends of the vertical air direction adjustment blades and the vertical air direction adjustment blades. Near the center, that is, in the vicinity of the connecting portion with the angle adjusting mechanism. For this reason, each protrusion mechanism is arrange | positioned in the vicinity of the both ends of an up-and-down wind direction adjustment blade | wing and the angle adjustment mechanism vicinity. As described above, when there are a plurality of projecting mechanisms, the vertical wind direction adjusting blades can be stably moved as compared with the case where the vertical wind direction adjusting blades are moved out by the two projecting mechanisms.

  In the above embodiment, the indoor unit 10 includes the single angle adjustment mechanism 71.

  Instead of this, the indoor unit may include a plurality of angle adjustment mechanisms. When the indoor unit includes a plurality of angle adjustment mechanisms, the vertical air direction adjustment blades are more stable than when the angle of inclination of the vertical air direction adjustment blades with respect to the outlet is changed by one angle adjustment mechanism. Can be moved.

(D)
In the said embodiment, the blower outlet 15 is formed in the lower part vicinity of the indoor unit 10. FIG. It replaces with this and the blower outlet may be provided in the front part of the indoor unit. Specifically, the air outlet may be formed continuously from the front surface of the indoor unit casing to both side surfaces.

(E)
In the said embodiment, the blower outlet 15 is continuously formed from the bottom face of the indoor unit casing 12 to both side surfaces, and is covered with the up-and-down air direction adjustment blade 30 and the side shielding members 20 and 90. It may replace with this and the structure of the indoor unit in which the blower outlet is formed only in the bottom face of the indoor unit casing, and the blower outlet is covered only with the up-and-down air direction adjusting blades may be used.

(F)
In the above-described embodiment, the protrusion mechanisms 51 and 61 and the angle adjustment mechanism 71 shift from the first open state to the closed state until the state of the vertical airflow direction adjusting blade 30 shifts from the closed state to the first open state. Are driven simultaneously, until the transition from the first open state to the second open state or the third open state, and until the transition from the third open state or the second open state to the first open state. Are driven separately.

  Instead, the state of the up / down airflow direction adjusting blade transitions from the first open state to the second open state or the third open state and from the third open state or the second open state to the first open state. Also during this time, the protrusion mechanism and the angle adjustment mechanism may be driven simultaneously.

  Also, the protrusion mechanism and the angle adjustment mechanism 71 are separately provided until the state of the vertical airflow direction adjusting blade changes from the closed state to the first open state and also from the first open state to the closed state. It may be driven.

(G)
In the above embodiment, the inclination angle of the vertical airflow direction adjusting blade 30 with respect to the first portion 16 of the air outlet 15 is changed by the protrusion mechanisms 51 and 61 and the angle adjusting mechanism 71.

  Instead of this, a mechanism similar to the protrusion mechanisms 51 and 61 of the above embodiment may be used instead of the angle adjustment mechanism. In other words, the inclination angle of the up-and-down air direction adjusting blades with respect to the opening surface corresponding to the first portion may be changed at the outlet by the three urging mechanisms.

  The present invention includes an up / down air direction adjusting blade because the possibility of interference between the up / down air direction adjusting blade and a member inside the indoor unit casing can be reduced when the inclination angle of the up / down air direction adjusting blade with respect to the air outlet is changed. Application of air conditioners to indoor units is effective.
