<Configuration of first mechanism>
The 1st mechanism 50 is for moving the up-and-down wind direction adjustment blade 30 so that it may be in the state where the 1st part 16 of blower outlet 15 is opened from the state where the 1st part 16 of blower outlet 15 is covered. Mechanism. Moreover, the 1st mechanism 50 changes the position of the 1st connection parts 32 and 33 and the 2nd connection part 34 with respect to the opening surface corresponded to the 1st part 16 in the blower outlet 15, and the state of the up-and-down wind direction adjustment blade | wing 30 Can be switched. The first mechanism 50 can switch the state of the up / down air direction adjusting blade 30 without changing the shape of the up / down air direction adjusting blade 30.

  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 and 33 can be slid. Specifically, the push-out mechanisms 51 and 61 can move the first connecting portions 32 and 33 so that the first connecting portions 32 and 33 are close to or separated from the outlet 15.

  Further, the push-out mechanisms 51 and 61 can move the positions of the first connecting portions 32 and 33 relative to the first portion 16 of the air outlet 15 by moving the first connecting portions 32 and 33. For example, the pushing-out mechanisms 51 and 61 can move the first connecting portions 32 and 33 arranged at the positions shown in FIG. 10 to the positions shown in FIG. Further, for example, the push-out mechanisms 51 and 61 can move the first connecting portions 32 and 33 arranged at the positions shown in FIG. 11 to the positions shown in FIG. Furthermore, the urging mechanisms 51 and 61 move the vertical airflow direction adjusting blade 30 to the air outlet 15 by moving the positions of the first connecting portions 32 and 33 with respect to the first portion 16 of the air outlet 15 in a direction away from the air outlet 15. In FIG. 6, the first portion 16 can be moved forward from the opening surface. The thrusting mechanisms 51 and 61 function as a speed increasing mechanism that transmits driving force of thrusting mechanism driving motors 54 and 64 to be described later to the first coupling portions 32 and 33 of the vertical airflow direction adjusting blade 30.

  Further, as shown in FIGS. 8 and 9, the protrusion mechanisms 51 and 61 move the first protrusion mechanism 51 capable of moving the left first connecting portion 32 and the right first connecting portion 33. And a second ejection mechanism 61 capable of performing the above-described operation. 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. 8 and 9, 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 made of a member (high sliding member) having excellent slidability, and protrudes outward from the end surface near 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 vertical airflow direction adjustment blade 30 in parallel with the longitudinal direction of the vertical airflow direction adjustment blade 30, and rotatably supports the shaft support portion 32a. For this reason, the support shaft 57 can smoothly rotate the shaft support portion 32a while suppressing friction. Further, the support shaft 57 has a bent end, and the support shaft 57 is structured not to fall out of the shaft support portion 32a. Therefore, the thrusting mechanisms 51 and 61 can cope with the front-rear direction inclination of the up / down air direction adjusting blade 30 and the right / left direction inclination of the lower air direction adjusting blade 30.

  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. 8 and 9, the end portions of the moving members 53 and 63 that are connected to the up and down airflow direction adjusting blades 30 are the lower end portions 53 a and 63 a of the moving members 53 and 63, and the lower end portions thereof. 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. In this manner, the protrusion mechanisms 51 and 61 can adjust the distance from the first portion 16 of the air outlet 15 to the first connecting portions 32 and 33.

  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 so that the vertical wind direction adjustment blade 30 and the angle adjustment mechanism 71 are adjusted such that the front-rear direction 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 2nd connection part 34 which is a connected part can be moved in the direction away from the blower outlet 15. FIG. Further, the angle adjusting mechanism 71 moves the second connecting portion 34 around the support shafts 57 and 67 pivotally supported by the first connecting portions 32 and 33, that is, the rotating shaft, so that the air outlet 15 can be moved. On the other hand, the 2nd connection part 34 arrange | positioned in a predetermined position can be moved to the position different from the said 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 connecting portion 34 of the vertical wind 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 is configured by a member having excellent slidability, and protrudes outward from both end surfaces of the arm 75 in the vicinity of the end opposite to the end connected to the swing lever 74. It is provided to do. The support shaft 78 rotatably supports the shaft support portion 34a of the up / down airflow direction adjusting blade 30. For this reason, the support shaft 78 can smoothly rotate the shaft support portion 34a while suppressing friction. Therefore, the angle adjustment mechanism 71 can cope with the forward / backward inclination of the up / down air direction adjusting blade 30 and the left / right inclination of the up / down air direction adjusting blade 30.

  For this reason, the link mechanism 72 is in a state in which the up-and-down air 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. When the swing lever 74 is in the position shown in FIG. 11 or FIG. 15, the state of the vertical airflow direction adjusting blade 30 is the first open state, the second open state, the third open state, or the fourth open state. It becomes a state. Further, when the swing lever 74 is at the position shown in FIG. 16, the state of the up / down airflow direction adjusting blade 30 is the fifth open state, the sixth open state, or the seventh open state. As described above, the angle adjustment mechanism 71 can adjust the distance from the first portion 16 of the air outlet 15 to the second connecting portion 34.

  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 fourth open state. 1 The connection parts 32 and 33 are 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 fourth 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 34 is not moved.

  With this configuration, the angle adjusting mechanism driving motor 73 is driven, whereby the second connecting portion 34 of the up / down airflow direction adjusting blade 30 can be pushed and pulled. 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 portions 32 and 33 by the projecting mechanisms 51 and 61, and is adjusted by the angle adjusting mechanism 71. By adjusting the distance from the 1st part 16 to the 2nd connection part 34, the inclination-angle with respect to the opening surface corresponded 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 fourth open state, the urging mechanisms 51 and 61 use the support shaft 78 pivotally supported by the second connecting portion 34 as the rotation axis. The 1st connection parts 32 and 33 are moved. Further, when the vertical airflow direction adjusting blade 30 is switched from the fourth open state to the fifth open state, the angle adjusting mechanism 71 rotates the support shafts 57 and 67 that are pivotally supported by the first connecting portions 32 and 33. The 2nd connection part 34 is moved as an axis | shaft. Therefore, the support shaft that is pivotally supported by one of the first connecting portions 32 and 33 in the vicinity of the front end 30f and the second connecting portion 34 in the vicinity of the rear end 30e of the vertical airflow direction adjusting blade 30 is used as a rotating shaft. And the inclination angle of the up-and-down air direction adjustment blade | wing 30 with respect to the 1st part 16 of the blower outlet 15 is changed by moving the connection part which is supporting the other support shaft which is not functioning as a rotating 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. 8 and 9, 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.

<Control unit>
FIG. 19 is a control block diagram of the control unit 84 provided in the air conditioner 1.

  As shown in FIG. 19, the control unit 84 is connected to various devices such as the indoor unit 10 and the outdoor unit 2, and is based on an operation command from a person to be air-conditioned via the remote controller 86. It is possible to perform operation control of various devices according to each operation mode.

  The remote controller 86 is provided with a plurality of switches such as an operation stop / start button and a wind direction setting button 86a. The operation stop / start button is a switch that is operated when the operation of the air conditioner 1 is stopped by the air conditioning subject or when the operation is started. The wind direction setting button 86a is a switch that is operated when the blowing direction of the air blown out from the indoor unit 10 by the air conditioning subject is set. For example, when the wind direction setting button 86a is pressed by the air conditioning subject, the control unit 84 receives a wind direction setting command from the air conditioning subject as a control signal. Note that the wind direction setting command in the present embodiment includes a first command, a second command, a third command, a fourth command, a fifth command, a sixth command, and a seventh command. The first command is a command for setting the air blowing direction so that conditioned air blows out to the front upper side and the side of the indoor unit 10. The second command is a command for setting the air blowing direction so that the conditioned air blows out to the front upper side and the right side of the indoor unit 10. The third command is a command for setting the air blowing direction so that conditioned air blows out to the front upper side and the left side of the indoor unit 10. The fourth command is a command for setting the air blowing direction so that the conditioned air blows out to the lower front side of the indoor unit 10. The fifth command is a command for setting the air blowing direction so that conditioned air blows out below the indoor unit 10. The sixth command is a command for setting the air blowing direction so that conditioned air blows out downward and to the right of the indoor unit 10. The seventh command is a command for setting the air blowing direction so that conditioned air blows out downward and to the left of the indoor unit 10. For this reason, the control part 84 determines the operation mode and air blowing direction of the air conditioner 1 based on the operation start command and the wind direction setting command made by the air conditioning subject.

  Further, the control unit 84 has a drive control unit 85 for switching the state of the up / down airflow direction adjusting blade 30. 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 individually controls the rotation speed and rotation direction of 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 adjustment blade 30. Switch.

  Further, the drive control unit 85 can individually control the protrusion mechanism driving motor 54 and the protrusion mechanism driving motor 64. For this reason, the drive control part 85 controls the drive amount of each protrusion mechanism drive motor 54,64, and the distance from the blower outlet 15 to the left side 1st connection part 32, and the right side 1st connection from the blower outlet 15. The distance to the portion 33 can be made equal or different. Specifically, the drive control unit 85 controls the movement amounts of the first ejection mechanism driving motors 54 and 64 so that the movement amounts of the first ejection mechanism 51 and the second ejection mechanism 61 are the same. Therefore, the distance from the blower outlet 15 to the left first connecting part 32 and the distance from the blower outlet 15 to the right first connecting part 33 can be made equal. In addition, the drive control unit 85 makes the movement amount of the first ejection mechanism larger than the drive amount of the ejection mechanism driving motor 64 by making the driving amount of the ejection mechanism driving motor 54 larger than the driving amount of the second ejection mechanism. Therefore, the distance from the air outlet 15 to the left first connecting portion 32 can be made larger than the distance from the air outlet 15 to the right first connecting portion 33. Further, the drive control unit 85 makes the movement amount of the first ejection mechanism smaller than the drive amount of the ejection mechanism driving motor 64 by making the driving amount of the ejection mechanism driving motor 54 smaller than the driving amount of the second ejection mechanism. Therefore, the distance from the air outlet 15 to the left first connecting portion 32 can be made smaller than the distance from the air outlet 15 to the right first connecting portion 33.

  In this way, the drive control unit 85 controls the two thrust mechanism drive motors 54 and 64 and the angle adjustment mechanism drive motor 73 to move the vertical wind direction adjusting blade 30 forward and backward with respect to the outlet 15. In addition, it can be inclined in the left-right direction.

<Switching control by the control unit>

In the following description, for convenience of explanation, when the first connecting portions 32 and 33 move away from the air outlet 15, the rotation direction in which the thrust mechanism driving motors 54 and 64 rotate is defined as the first direction. The second direction is the rotation direction in which the thrust mechanism driving motors 54 and 64 rotate when the first connecting portions 32 and 33 move so as to approach the air outlet 15. Moreover, when the 2nd connection part 34 moves so that it may leave | separate with respect to the blower outlet 15, the rotation direction which the angle adjustment mechanism drive motor 73 rotates is made into the 3rd direction, and the 2nd connection part 34 becomes the blower outlet 15. On the other hand, the rotation direction in which the angle adjustment mechanism driving motor 73 rotates when moving so as to be close to each other is a fourth direction. Furthermore, the driving amount of the thrust mechanism driving motors 54 and 64 required for switching the vertical airflow direction adjusting blade 30 from the closed state to the first open state is set as the first driving amount, and the vertical airflow direction adjusting blade 30 is set to the first airflow adjusting blade 30. The drive amount of the thrust mechanism drive motors 54 and 64 required for switching from the open state to the fourth open state is defined as the second drive amount. Further, the driving amount of the angle adjustment mechanism driving motor 73 required for switching the up / down air direction adjusting blade 30 from the closed state to the first open state is set as the third driving amount, and the up / down air direction adjusting blade 30 is set in the fourth open state. The drive amount of the angle adjustment mechanism drive motor 73 required for switching from the first to the fifth open state is the fourth drive amount.

FIG.

  The side shielding members 20 and 90 are disposed at the left and right side lower portions of the indoor unit 10. Specifically, the side shielding members 20 and 90 are plate-like members having a substantially L-shaped cross section in a predetermined direction, and are formed from the bottom surface to the side surface of the indoor unit casing 12 at the air outlet 15. It is possible to cover the opening. For this reason, the side shielding members 20 and 90 can cover a portion 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, when the side shielding members 20 and 90 are in a state where the side shielding members 20 and 90 and the up and down airflow direction adjusting blades 30 are shielding the air outlet 15, the side shielding members 20 and 90 are arranged in the bottom view of the indoor unit 10. A part of the side shielding members 20 and 90 covering the opening formed in the bottom surface of the indoor unit casing 12 in the outlet 15 and the vertical airflow direction adjusting blades 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. 21 and 22, 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 the 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 (FIGS. 21 and 22). reference). 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. 23). . 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.

  Here, “shielding” means a state in which substantially all of the predetermined portion is covered by a member capable of covering the predetermined portion of the air outlet 15. The term “open” as used herein means a state in which substantially all of the predetermined portion is not covered with a member capable of covering the predetermined portion of the air outlet 15.

<Configuration of second mechanism>
The second mechanism is a moving mechanism different from the first mechanism 50, and the second portion 17 a and the third portion 17 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. This is a mechanism capable of moving the side shielding members 20, 90 so that the portion 17b is opened. In other words, the second mechanism is a mechanism for moving the side shielding members 20 and 90 in order to switch the state of the side shielding members 20 and 90.

  The second mechanism has a second mechanism drive motor (not shown) for rotating a rotary shaft extending in the front-rear direction of the indoor unit 10. The second mechanism driving motor is disposed in the indoor unit body 11 and is fixed to the indoor unit casing 12. Further, the rotation shaft is connected to a support member arranged in the vicinity of the first end 90a of the side shielding member 90, and the support member can be moved in the rotation direction around the rotation axis by rotating. .

  With such a configuration, in the second mechanism, the rotation shaft rotates when the second mechanism driving motor is 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.

  In addition, the second mechanism includes storage portions 25 and 95 for storing the side shielding members 20 and 90 in the open state. The accommodating part 25 is arrange | positioned in the 3rd part 17b vicinity of the blower outlet 15. FIG. Further, the storage portion 95 is disposed in the vicinity of the second portion 17a of the air outlet 15.

  Next, the configuration of the storage units 25 and 95 will be described. Since the storage unit 25 is similar to the configuration in which the configuration of the storage unit 95 is bilaterally symmetric, only the configuration of the storage unit 95 will be described here, and the description of the configuration of the storage unit 25 will be omitted.

  As shown in FIGS. 22 and 23, the storage unit 95 includes a first wall portion 96 and a second wall portion 97 that form a storage space in which the left-side shielding member 90 in an open state is stored. . The first wall portion 96 extends upward from the vicinity of the second portion 17 a of the air outlet 15. The first wall portion 96 has a curved shape so as to correspond to the left side shielding member 90, and the upper end portion of the first wall portion 96 is more indoor than the lower end portion of the first wall portion 96. 11 is disposed so as to be closer to the center side.

  The second wall 97 extends upward from the vicinity of the boundary between the first portion 16 of the air outlet 15 and the second portion 17a of the air outlet 15. The second wall 97 has a curved shape so as to be compatible with the left-side shielding member 90, and the upper end of the second wall 97 is more indoor than the lower end of the second wall 97. 11 is disposed so as to be closer to the center side. Further, the upper end portion of the storage portion 95, that is, the upper end portion of the second wall portion 97 and the upper end portion of the first wall portion 96 have a continuous configuration.

  Further, the vertical blades 19 are arranged near the indoor fan 14 rather than the upper ends of the storage portions 25 and 95. Further, the storage portions 25 and 95 are the tip portions of the blades when the blades closest to the storage portions 25 and 95 among the plurality of blades 19a of the vertical blade 19 swing and incline. Are arranged so as to be positioned in the vicinity of the upper end portions of the storage portions 25 and 95, respectively. Therefore, when the air flow is generated by the indoor fan 14 with the vertical blades 19 swinging in the left-right direction, the first wall in which the conditioned air is inclined toward the left side or the right side. The second portion 17a and the third portion 17b of the air outlet 15 that are restricted by the guide surface of the first wall portion and open toward the side of the indoor unit 10 along the guide surface of the first portion. Is blown out.

  With such a configuration, when the side shielding members 20 and 90 are in the open state, the control unit 84 controls the vertical blades 19 to swing in the left-right direction, so that conditioned air It can be blown out toward the left and right sides of the machine 10. Therefore, since the side of the air outlet 15 is covered with the side shielding members 20 and 90, air can be blown out toward the side as needed.

(B)
In the said embodiment, the direction which the air which blows off from the blower outlet 15 heads is determined based on the wind direction setting command from the air conditioning subject.

  Instead of this, for example, the wind direction according to each operation mode is set in advance, and the posture of the vertical wind direction adjusting blade is set so that the wind direction is based on the command only when the wind direction setting command is issued by the air conditioning subject. May be changed. Moreover, as a state of the up-and-down air direction adjustment blade set in advance, it is assumed that the conditioned air is in the lower part of the first space in the indoor space, that is, the person to be air-conditioned is in the lower part of the indoor space during the cooling operation. It is controlled to be in the fourth open state, which is the state of the up / down airflow direction adjusting blades toward the space, and during heating operation, the conditioned air is in the state of the up / down airflow direction adjusting blades toward the lower part of the second space in the indoor space. It may be controlled to be in five states. In this way, in the cooling operation in which the conditioned air having a temperature lower than the indoor temperature is likely to be blown out, the state of the vertical airflow direction adjusting blade becomes the fourth state, so that the temperature in the lower part of the indoor space is effective. Can be lowered. In addition, during the heating operation in which conditioned air having a temperature higher than the room temperature is likely to be blown out, the state of the up-and-down airflow direction adjusting blade becomes the fifth state, so that the conditioned air is difficult to accumulate in the upper part of the indoor space. Therefore, the temperature of the lower part of the indoor space can be effectively increased.

(C)
In the above embodiment, the air outlet 15 is formed in the lower part of the indoor unit 10. For this reason, for example, when the up-and-down air direction adjusting blade 30 is in the second open state, the up-and-down air direction adjusting blade 30 is formed on the opening surface corresponding to the first portion 16 of the outlet 15 in the front view of the indoor unit 10. On the other hand, it is inclined to the left.

  It may replace with this and the blower outlet may be formed in the front part of an indoor unit, ie, the front side of an indoor unit. In this case, when viewed from the bottom of the indoor unit, the first coupling portion may be moved by the urging mechanism so that the vertical airflow direction adjusting blades are arranged to be inclined in the left-right direction with respect to the opening surface of the outlet.

(D)
In the above embodiment, the end of the support shaft 57 has a bent shape.

  Instead, the end of the support shaft may be spherical.

  For example, as shown in FIG. 24, the case where the up-and-down wind direction adjustment blade | wing 30 is supported by the support shaft 157 whose edge part 157a is spherical shape is demonstrated. In the present modification, the configuration other than the first connection portion 132 and the support shaft 157 is the same as that of the above embodiment, and thus the description thereof is omitted. In FIG. 24, the configuration other than the first connection portion 132 and the support shaft 157 is omitted. These members are denoted by the same reference numerals as the members of the above embodiment.

  The 1st connection part 132 is comprised from the 1st part 132a and the 2nd part 132b. The first portion 132 a and the second portion 132 b are arranged side by side in the insertion direction of the support shaft 157. Moreover, the 1st part 132a and the 2nd part 132b contain the axial support parts 135 and 136, as shown in FIG. Each shaft support part 135, 136 supports the support shaft 157 in a rotatable manner. Further, the bearing surface 135a of the shaft support portion 135 of the first portion 132a has a tapered shape that allows the support shaft 157 to move in the direction intersecting the horizontal direction around the end portion 157a of the support shaft 157. The shaft support 136 of the second part 132b has a spherical concave surface corresponding to the outer peripheral surface of the spherical end 157a of the support shaft 157 as the bearing surface 136a. For this reason, a part of the bearing surface 135a of the first portion 132a and the bearing surface 136a of the second portion 132b abut on the support shaft 157, so that the end portion 157a can be slid in the direction intersecting the horizontal direction. The support shaft 157 can be supported.

  As described above, when the shaft support portions 135 and 136 have the aligning function, they correspond to the forward / backward inclination of the vertical airflow direction adjusting blade 30 and the horizontal inclination of the vertical airflow direction adjusting blade 30. Can do.

(E)
In the above embodiment, the driving of the vertical blades is controlled by the control unit 84 according to the state of the up / down airflow direction adjusting blade 30.

  Instead of this, the person to be air-conditioned may be able to set whether the vertical blade is swung in the left-right direction or stopped in a predetermined state.

  Since this invention can blow off the air to the side of an indoor unit, application to an air conditioner is effective.
