(2) Detailed structure (2-1) Horizontal flap The detailed structure of the horizontal flap 30 is demonstrated using FIG.1, FIG2 and FIG.4. FIG. 4 is a partial perspective view for explaining the configuration of the lower part of the air-conditioning indoor unit in a state in which the horizontal flap opens the air outlet 15. The horizontal flap 30 is a substantially rectangular plate-like member, and is in a position that covers the opening of the air outlet 15 (hereinafter referred to as a fully closed position) when the air conditioning indoor unit 10 stops operating. The first surface 30 a that can be visually recognized from the outside in the fully closed position of the horizontal flap 30 constitutes a part of the lower surface of the main casing 13.

  A first front connecting portion 311, a second front connecting portion 312 and a third front connecting portion 313 are provided on the second surface 30 b which is the back surface of the first surface 30 a of the horizontal flap 30. The first front connecting part 311, the second front connecting part 312 and the third front connecting part 313 are substantially along the longitudinal direction of the second surface 30b on the front end side of the second surface 30b in the closed position of the horizontal flap 30. It is arranged at equal intervals. The horizontal flap 30 rotates around a rotation shaft 310 connecting the first front connection part 311, the second front connection part 312 and the third front connection part 313. In addition, a first rear connection part 321 and a second rear connection part 322 are provided on the second surface 30 b of the horizontal flap 30. The first rear connecting portion 321 and the second rear connecting portion 322 are arranged at the center in the longitudinal direction of the second surface 30 b on the rear end side of the second surface 30 b in the closed position of the horizontal flap 30.

  One end of three rod-shaped rack members 57 that bend and extend in an arc shape are connected to the first front connecting portion 311, the second front connecting portion 312 and the third front connecting portion 313, respectively. The rack member 57 is formed with a rack 57a of a rack and pinion mechanism on a convexly curved side surface, and takes a posture in which the rack 57a is directed obliquely upward in order to mesh with a pinion gear 55 described later.

  As shown in FIG. 1, one end of a foldable link member 58 is connected to each of the first rear connecting part 321 and the second rear connecting part 322. The link member 58 has a configuration in which ends of two rod-shaped members are joined to each other so as to be foldable in order to be foldable. Of the two rod-like members of the link member 58, the upper side of the node 58c is called the upper link 58a, and the lower side is called the lower link 58b.

The rack driving motor 51a is a stepping motor. The pinion gear 55 meshes with the rack 57a, and the rack driving motor 51a rotates the pinion gear 55 counterclockwise CCW when viewed from the left side, so that the rack member 57 moves toward the front of the air outlet 15. Thus, the operation in which the front portion of the horizontal flap 30 projects toward the front of the air outlet 15 is referred to as a first operation of the rack driving motor 51a. Conversely, the rack driving motor 51a rotates the pinion gear 55 clockwise, so that the rack member 57 moves backward toward the inner side of the main casing 13. This is called the second operation of the rack driving motor 51a.

  Further, a link drive motor 51b is mounted inside the main body casing 13, and a drive gear 56 is attached to the rotation shaft of the link drive motor 51b. The link driving motor 51b is a stepping motor. Further, a driven gear (not shown) is provided at the end of the upper link 58 a of the link member 58, and the link driving motor 51 b rotates the driven gear in the first direction via the driving gear 56. As a result, the central angle formed by the upper link 58a and the lower link 58b is expanded around the node 58c, and the rear portion of the horizontal flap 30 moves forward toward the front of the blowout port 15. This is called the first operation of the link driving motor 51b. Conversely, when the drive gear 56 rotates the driven gear in the second direction opposite to the first direction, the central angle formed by the upper link 58a and the lower link 58b is reduced around the node 58c, and the horizontal flap is reduced. The rear part of 30 retreats toward the outlet 15. This is called the second operation of the link driving motor 51b.

  The first operation of the rack driving motor 51a and the first operation of the link driving motor 51b described above are performed simultaneously or successively, so that both the front end side and the rear end side of the horizontal flap 30 are blown. It approaches toward the front of the exit 15. Further, the second operation of the rack driving motor 51a and the second operation of the link driving motor 51b are executed simultaneously or successively, so that both the front end side and the rear end side of the horizontal flap 30 are blown. Retreat toward exit 15. The horizontal flap 30 can take various postures by a combination of the first operation and the second operation of the rack driving motor 51a and the first operation and the second operation of the link driving motor 51b.

(2-2) Auxiliary Flaps As shown in FIG. 1, two auxiliary flaps 130 are provided along the longitudinal direction of the air outlet 15 at the rear portion of the air outlet 15. These two auxiliary flaps 130 have a rotating shaft 130 a shown in FIG. 2, and the rotating shaft 130 a is arranged in parallel with the longitudinal direction of the blowout port 15. These rotating shafts 130a are driven by an auxiliary flap driving motor 51c shown in FIGS. The auxiliary flap drive motor 51c is a stepping motor. As can be seen from FIG. 2, the auxiliary flap 130 has a width that covers almost half of the air outlet 15 from the rear edge of the air outlet 15 in a state in which the front end of the auxiliary flap 130 is most forward.

  Two central support portions 131 that support one end of the rotating shaft 130a of the auxiliary flap 130 are provided at positions facing the central portion of the air outlet 15 in the main casing 13 (see FIG. 1). Further, a side support portion 132 that supports the other end of the rotating shaft 130 a of the auxiliary flap 130 is provided at the rear corner of the air outlet 15 in the main body casing 13.

  As shown in FIG. 2, when the horizontal flap 30 is in the closed position, the auxiliary flap 130 is stored above the horizontal flap 30 in a posture substantially parallel to the horizontal flap 30, and from the outside. can not see. In the following description, this position where the auxiliary flap 130 is stored is referred to as an auxiliary flap storage position. When the auxiliary flap 130 is in the auxiliary flap storage position, the auxiliary flap 130 is close to the second surface 30b of the horizontal flap 30, and the space that the auxiliary flap 130 occupies the outlet flow path 18 is small. The peripheral flaps 18 and the blowout flow path 18 do not interfere with the vertical flaps 20 that are fully open on the left and right. In the following description, a state in which the vertical flap 20 is fully opened on the left and right is referred to as a wide position. This wide position is also a storage position where the vertical flap 20 is stored when the operation is stopped.

(2-3) Vertical Flap As shown in FIGS. 1, 5, and 6, the vertical flap 20 includes a plurality of blade pieces 201 and a connecting rod 203 that connects the plurality of blade pieces 201. Yes. In addition, as shown in FIG. 2, the vertical flap 20 is disposed above the second surface 30 b and the auxiliary flap 130 of the horizontal flap 30 in the closed position, that is, on the side close to the indoor fan 12 in the outlet flow path 18. Yes.

  As shown in FIG. 5, the blade piece 201 is formed with a slit hole 201 a into which the connecting rod 203 is inserted on the air outlet 15 side, and is supported inside the main body casing 13 on the end on the indoor fan 12 side. A support portion 201b is formed. In addition, the blade piece 201 is formed with two slits 201c extending from the central portion toward the support portion 201b. For example, when the connecting rod 203 moves along the longitudinal direction of the outlet 15, in the blade piece 201, the portion sandwiched between the two slits 201 c is bent as a cantilever with the support portion 201 b as a fixed end. . Therefore, as the connecting rod 203 moves, the tip of the blade piece 201 can be turned to the side surface side of the main body casing 13.

  FIG. 6A shows a state in which the blade piece 201 is in a wide position during operation stop or operation, and FIG. 6B shows a state of the blade piece 201 in which air is blown out toward the front during operation. Is shown. The plurality of blade pieces 201 swing left and right around a state perpendicular to the longitudinal direction of the main casing 13 as the connecting rod 203 horizontally reciprocates along the longitudinal direction of the air outlet 15. The connecting rod 203 is reciprocated horizontally by the left flap drive motor 52a and the right flap drive motor 52b of the vertical flap drive mechanism 52. The left flap driving motor 52a and the right flap driving motor 52b are stepping motors. The left flap drive motor 52a and the right flap drive motor 52b are each attached to one end of a foldable arm 204. The other end of the arm 204 is connected to the central portion of the swing bar 205. The swinging rod 205 has one end connected to the fulcrum and the other end connected to the connecting rod 203. Therefore, as the left flap driving motor 52a and the right flap driving motor 52b rotate, the other end of the arm 204 swings the swinging rod 205 left and right, and the swinging rod 205 moves the connecting rod 203 around the fulcrum. Move back and forth horizontally.

  The blade piece 201 not only swings but can stop at any angle by stopping the motor after swinging. Therefore, the blade piece 201 is a front blown state (see FIG. 6B) in which the air blowing state from the blowout port 15 is blown to the front side of the main body casing 13 or an oblique blown blown to the side surface side of the main body casing 13. The blown air can be guided to the left and right within a predetermined angle range such as the state (see FIG. 6A).

  Further, as the blade piece 201 of the vertical flap 20 has a longer dimension in the blowing direction, the air at the side blowing can be directed in the target direction. Since the design is greatly designed to improve the wind direction control performance of the vertical flap 20 and the auxiliary flap 130, the blade piece 201 directed toward the front direction rather than the wide state interferes with the auxiliary flap 130 at the auxiliary flap storage position. To do.

(3) Flap operation (3-1) Operation start operation at position on rack Next, operation start operation at the position on the rack by the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 will be described with reference to FIGS. . The control described with reference to FIG. 7 to FIG. 12 is an operation start operation in the case where the blown air is blown out downward of the air conditioning indoor unit 10 during heating, for example. In order to direct the blown air downward, the rack member 57 is lowered for the purpose of opening the air outlet 15, and then the horizontal flap in a state where the rack member 57 is relatively raised (position on the rack) to control the vertical air direction. The indoor control unit 41 controls the 30 postures (see FIG. 10). FIG. 7 is a timing chart showing the operations of the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 at the start of operation on the position on the rack. FIG. 9 is a flowchart for explaining the control of the indoor control unit 41. In FIG. 7, the position of the rack member 57 that supports the horizontal flap 30 is displayed as the rack position, the position of the link member 58 that supports the horizontal flap 30 is displayed as the link position, and the attitude of the auxiliary flap 130 is displayed as the auxiliary flap position. ing. Further, the posture of the vertical flap 20 is displayed in FIG. 7 as the left flap position and the right flap position divided into the left flap 20a and the right flap 20b shown in FIG.

  In the indoor control unit 41, first, before the time t1 in FIG. 7, it is determined whether or not there is an instruction to start driving from a user or the like, or whether or not it is time to automatically start driving ( Step S1). Here, when it is determined that the operation is started, it is determined whether or not the wind direction control by the horizontal flap 30 is performed at the position on the rack (step S2). If it is determined in step S2 that the wind direction control at the position on the rack is performed, the operation after time t1 in FIG. 7 is started.

  When the time t1 has elapsed, the rack member 57 moves from the fully closed position Pr1 to the flap rubbing prevention rack position Pr2 (see FIG. 8B). When the time t1 has elapsed, the link member 58 moves from the fully closed position Pl1 to the flap rubbing prevention link position Pl2 simultaneously with the rack member 57. The fully closed position Pr1 of the rack member 57 and the fully closed position Pl1 of the link member 58 are positions of the rack member 57 and the link member 58 when the horizontal flap 30 closes the air outlet 15 (FIG. 8A and FIG. 8). FIG. 11). The position of the vertical flap 20 indicated by the dotted line in FIG. 11 is a position that can be taken during operation, and the vertical flap 20 in the dotted line position and the auxiliary flap 130 in the auxiliary flap storage position are mutually connected as can be seen from FIG. have a finger in the pie.

  The horizontal flap 30 is temporarily moved from the fully closed state where the blower outlet 15 is closed to the flap rubbing prevention position (see FIG. 12) because the horizontal flap 30 is moved by the wind direction control operation of the horizontal flap 30 by the rack member 57 and the link member 58. The purpose is to prevent the main casing 13 from rubbing. Further, the flap rubbing prevention rack position Pr2 of the rack member 57 and the flap rubbing prevention link position Pl2 of the link member 58 are horizontal to the auxiliary flap 130 even when the auxiliary flap 130 is in the non-interference position as shown in FIG. This is the position of the rack member 57 and the link member 58 when the horizontal flap 30 is in the flap rubbing prevention position (see FIG. 12) where the flap 30 does not hit.

  Further, when the time t1 has elapsed, the auxiliary flap 130 also moves toward the fully closed position Pa4, and the origin is determined. In FIG. 7, the portion indicated by the dotted line between time t1 and time t2 is the state in which the auxiliary flap 130 reaches the fully closed position Pa4 and cannot move further in the closing direction, and is not moved by the auxiliary flap driving motor 51c. A state where torque is applied is shown. As a result, the state in which the auxiliary flap 130 is surely positioned at the fully closed position Pa4, that is, the origin search is performed.

  At time t2, the horizontal flap 30 has reached the flap rubbing prevention position, and the auxiliary flap 130 is in a state where the origin search has been completed (step S3). Next, the auxiliary flap 130 moves to the non-interference position Pa3 (step S4). The non-interference position Pa3 is a position where the auxiliary flap 130 and the vertical flap 20 do not contact each other regardless of the direction of the vertical flap 20 (see FIGS. 8C, 8D, and 8F). ). At time t2, the vertical flap 20 has the left flap 20a in the left fully open position (left flap wide position) Pn3 and the right flap 20b in the right fully open position (right flap wide position) Pm1. The right fully open position Pm1 is a state in which the right flap 20b is closest to the right side surface of the main casing 13, and is a position for guiding the blown air toward the right side (see FIG. 6A). The left fully open position Pn3 is a state in which the left flap 20a is closest to the left side surface of the main casing 13, and is a position for guiding the blown air toward the left side (see FIG. 6A).

  At time t3, since the auxiliary flap 130 has reached the non-interference position Pa3, even if the vertical flap 20 moves, it does not interfere with the auxiliary flap 130. Therefore, the memory angular positions of the right flap 20b and the left flap 20a of the vertical flap 20 The movement to Pm2 and Pn2 is started (step S5). The memory angular positions Pm2 and Pn2 are positions between the right fully opened positions Pm1 and Pn1 and the left fully opened positions Pm3 and Pn3 and can be changed by the setting of the user, for example, when facing the front (see FIG. 6B). )and so on.

  At time t3, the rack member 57 starts to move from the flap rubbing prevention rack position Pr2 toward the fully open position Pr5. This is because the origin of the rack member 57 is performed at the fully open position Pr5 (step S5). The fully open position Pr5 of the rack member 57 is a position where the rack member 57 extends most when the horizontal flap 30 is opened (see FIG. 8C). The origin of the rack member 57 is set before and after the time t4, and the operation indicated by the dotted line near the time t4 is performed in the direction in which the rack member 57 is further extended with respect to the rack member 57 at the fully open position Pr5. This is an operation for driving the drive motor 51a. As a result, the state in which the rack member 57 is reliably located at the fully open position Pr5, that is, the origin search is performed.

  When the origin of the rack member 57 is finished after the time t4 has elapsed, the rack member 57 moves to the rack upper position Pr3 (step S6). At time t5, the movement of the rack member 57 to the rack upper position Pr3 is completed. The on-rack position Pr3 is a position of the rack member 57 mainly used when the air direction control for blowing the blown air downward is performed (see FIG. 10).

  At time t6, the movement of the link member 58 toward the fully open position Pl5 is started in order to find the origin of the link member 58. The fully open position Pl5 is a position where the link member 58 extends most (see FIG. 8E). At time t7, the origin of the link member 58 is determined (step S7). The origin of the link member 58 is performed before and after the time t7 (see FIG. 13), and the operation indicated by the dotted line near the time t7 is further performed with respect to the link member 58 at the fully open position Pl5. Is the operation of driving the link driving motor 51b in the direction of widening the angle formed by the upper link 58a and the lower link 58b.

  At time t8, in order to make the horizontal flap 30 and the auxiliary flap 130 follow the setting of the user or the like, the link member 58 is moved to the link memory angular position Pl4 while the rack member 57 is stopped at the rack upper position Pr3, and the auxiliary flap 130 is moved. Is moved to the auxiliary flap wind direction angle position Pa2 (step S7). The link memory angle position Pl4 is a position of the link member 58 for realizing the posture of the horizontal flap 30 stored before the operation stop. The auxiliary flap wind direction angle position Pa <b> 2 is an example of a position where the auxiliary flap 130 performs the wind direction control, and is a position that can be changed by setting of a user or the like (see FIG. 8F). Therefore, the link memory angle position Pl4 and the auxiliary flap wind direction angle position Pa2 can be changed according to an instruction from a user or the like.

(3-2) Operation Start Operation at Rack Lower Position Next, operation start operation at the rack lower position by the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 will be described with reference to FIGS. The control described with reference to FIG. 14 to FIG. 18 is an operation start operation when the air is blown out toward the front of the air conditioning indoor unit 10 mainly during cooling. After the rack member 57 is lowered to open the air outlet 15 in order to direct the blown air forward, the horizontal flap is in a state where the rack member 57 is relatively lowered (rack lower position) to control the vertical air direction. The indoor control unit 41 controls the 30 postures (see FIG. 17). FIG. 14 is a timing chart showing the operations of the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 at the start of operation at the position below the rack. FIG. 16 is a flowchart for explaining the control of the indoor control unit 41.

  First, in the indoor control unit 41, as shown in FIG. 9, before the time t11 in FIG. 14, it is determined whether or not there is an instruction to start the operation from the user or the like, or at the time when the operation is automatically started. Judgment is made as to whether or not (step S1). Here, when it is determined that the operation is started, it is determined whether or not the wind direction control by the horizontal flap 30 is performed at the position on the rack (step S2). If it is determined in step S2 that the wind direction control at the position above the rack is not performed, that is, the wind direction control at the position below the rack, the operation after time t11 in FIG.

  From the fully closed state in which the horizontal flap 30 closes the air outlet 15 at the time t11, the rack member 57 changes from the fully closed position Pr1 (FIG. 15 (a)) to the flap rubbing prevention rack position Pr2 (FIG. 15 (b)). Move to. When the time t11 has elapsed, the link member 58 moves from the fully closed position Pl1 (FIG. 15A) to the flap rubbing prevention link position Pl2 (FIG. 15B) simultaneously with the rack member 57. Further, when the time t1 has elapsed, the auxiliary flap 130 also moves toward the fully closed position Pa4, and the origin is determined.

  At time t12, the horizontal flap 30 has reached the flap rubbing prevention position, and the auxiliary flap 130 is in a state where the origin search has been completed (step S10). Next, the auxiliary flap 130 moves to the non-interference position Pa3 (step S11). At time t12, the vertical flap 20 has the left flap 20a in the left fully open position (left flap wide position) Pn3 and the right flap 20b in the right fully open position (right flap wide position) Pm1.

  At time t13, since the auxiliary flap 130 has reached the non-interference position Pa3, even if the vertical flap 20 moves, it does not interfere with the auxiliary flap 130. Therefore, the memory angular positions of the right flap 20b and the left flap 20a of the vertical flap 20 The movement to Pm2 and Pn2 is started (step S12).

  Further, after the time t13, the rack member 57 starts moving from the flap rubbing prevention rack position Pr2 toward the fully open position Pr5. The origin of the rack member 57 is set before and after the time t14 (step S12), and the operation indicated by the dotted line near the time t14 further moves the rack member 57 to the rack member 57 at the fully open position Pr5. This is an operation of driving the rack driving motor 51a in the extending direction (see FIG. 15C).

  When the origin of the rack member 57 is finished after the time t14 has elapsed, the rack member 57 moves to the rack lower position Pr4 (step S13). At time t15, the movement of the rack member 57 to the rack lower position Pr4 is completed. The rack lower position Pr4 is a position of the rack member 57 mainly used when the air direction control for blowing the blown air forward is performed (see FIGS. 15D and 18).

  At time t16, the movement of the link member 58 toward the fully closed mechanism limit position Pl8 is started in order to return the origin of the link member 58. The fully closed mechanism limit position Pl8 is a position where the link member 58 is most contracted, and is a position where the members come into contact with each other and cannot move to the fully closed side (see FIG. 15D). At time t17, the origin of the link member 58 is determined (step S14). The origin of the link member 58 is performed before and after the time t17, and the operation indicated by the dotted line near the time t17 further moves the link member 58 to the link member 58 at the fully closed mechanism limit position Pl8. In this operation, the link driving motor 51b is driven in the direction of decreasing the angle formed by the upper link 58a and the lower link 58b.

  At time t18, in order to make the horizontal flap 30 and the auxiliary flap 130 follow the setting of the user or the like, the link member 58 is moved to the link memory angular position Pl6 while the rack member 57 is stopped at the rack lower position Pr4, and the auxiliary flap 130 is used. Is moved to the auxiliary flap wind direction angle position Pa2 (step S15). The link memory angle position Pl4 is a position of the link member 58 for realizing the posture of the horizontal flap 30 stored before the operation stop. The auxiliary flap wind direction angle position Pa2 (memory angle position of the auxiliary flap) is an example of a position where the auxiliary flap 130 performs the wind direction control, and is for realizing the posture of the auxiliary flap 130 stored before the operation is stopped. It is a position (refer FIG.15 (e) and FIG. 17). Therefore, the link memory angle position Pl4 and the auxiliary flap wind direction angle position Pa2 can be changed according to an instruction from a user or the like.

(3-3) Wind direction control operation (3-3-1) Change from rack lower position to rack upper position Next, the vertical flap 20, horizontal flap 30, and auxiliary flap 130 change the rack lower position to the rack upper position. The operation of changing the wind direction accompanied with the above will be described with reference to FIGS. FIG. 19 is a timing chart of the horizontal flap 30 and the auxiliary flap 130 showing the operation of changing from the rack upper position to the rack lower position, and FIG. 20 is a flowchart for explaining the operation. In FIG. 19, the description of the operation of the vertical flap 20 is omitted. This is omitted because the vertical flap 20 does not interfere with the horizontal flap 30 and the auxiliary flap 130 because the auxiliary flap 130 moves to the non-interference position Pa3.

  In the indoor control unit 41, for example, it is monitored whether or not the user has instructed the transmission / reception unit 44 to change the wind direction from the rack lower position to the rack upper position using a remote controller (step S21). When a user or the like gives a wind direction change instruction from the rack lower position to the rack upper position, the indoor control unit 41 stops the operations of the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130. Then, the operation after time t21 shown in FIG. 19 starts.

  At time t21, the auxiliary flap 130 starts moving toward the non-interference position Pa3. Further, the link member 58 of the horizontal flap 30 also starts moving toward the flap rubbing prevention link position Pl2. When the movement of the auxiliary flap 130 to the non-interference position Pa3 and the movement of the link member 58 to the flap rubbing prevention link position Pl2 are completed (step S23), the rack member 57 is moved from the rack lower position Pr4 to the rack upper position Pr3 at time t22. Start moving towards. At time t23, the rack member 57 completes the movement to the rack upper position Pr3 (step S24), and the link member 58 has moved to the fully open position Pl5.

  At time t24, the link member 58 reaches the fully open position Pl5, and the origination of the link member 58 starts. At time t25, the origination of the link member 58 ends (step S25).

  The link member 58 moves to the link memory angular position Pl4 when the origin is finished, and changes the horizontal flap 30 to the designated posture (step S26).

  At time t26, since the change in the wind direction control of the horizontal flap 30 is completed, the auxiliary flap 130 is moved from the non-interference position Pa3 to the auxiliary flap wind direction angle position Pa2.

  At time t27, the rack member 57 is moved to the upper position Pr3 and the link member 58 is moved to the link memory angular position Pl4, so that the change of the posture of the horizontal flap 30 is finished and the change of the posture of the auxiliary flap 130 is finished. .

(3-3-2) Change from the position on the rack to the position on the bottom of the rack Next, the operation of changing the wind direction accompanied by the change from the position on the rack to the position below the rack by the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 will be described. This will be described with reference to FIGS. FIG. 21 is a timing chart showing the operation of the horizontal flap 30 and the auxiliary flap 130 when changing from the rack upper position to the rack lower position, and FIG. 22 is a flowchart for explaining the operation. In FIG. 21, the description of the operation of the vertical flap 20 is omitted. This is omitted because the vertical flap 20 does not interfere with the horizontal flap 30 and the auxiliary flap 130 because the auxiliary flap 130 moves to the non-interference position Pa3.

  The indoor control unit 41 monitors, for example, whether or not the user has instructed the transmission / reception unit 44 to change the wind direction from the rack lower position to the rack upper position using a remote controller (step S31). When a user or the like gives a wind direction change instruction from the rack upper position to the rack lower position, the indoor control unit 41 stops the operations of the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130. Then, the operation after time t31 shown in FIG.

  At time t31, the auxiliary flap 130 starts moving toward the non-interference position Pa3. Further, the link member 58 of the horizontal flap 30 also starts moving toward the flap rubbing prevention link position Pl2. When the movement of the auxiliary flap 130 to the non-interference position Pa3 and the movement of the link member 58 to the flap rubbing prevention link position Pl2 are completed (step S33), the rack member 57 is moved from the rack upper position Pr3 to the rack lower position Pr4 at time t32. Start moving towards. At time t33, the rack member 57 has finished moving to the rack lower position Pr4 (step S34), and the link member 58 has moved to the fully closed mechanism limit position Pl8. At time t33, the origin of the rack member 57 may be determined. In that case, after the rack member 57 is once moved to the fully closed position Pr5 and the origin is set, the rack member 57 is moved to the rack lower position Pr4.

  At time t34, the link member 58 reaches the fully-closed mechanism limit position Pl8 and the home search of the link member 58 starts, and at time t35, the home search of the link member 58 ends (step S35).

  When the origin is finished, the link member 58 moves to the link memory angular position Pl6 and changes the horizontal flap 30 to the designated posture (step S36).

  At time t36, the change in the wind direction control of the horizontal flap 30 is completed, and the auxiliary flap 130 is moved from the non-interference position Pa3 to the designated auxiliary flap wind direction angle position Pa2.

  At time t37, the movement of the rack member 57 to the rack lower position Pr4 and the movement of the link member 58 to the link memory angular position Pl4 are completed, the change of the attitude of the horizontal flap 30 is completed, and the attitude of the auxiliary flap 130 is changed. The change has been completed.

(3-4) Operation Stop Operation Next, the operation stop operation at the position below the rack by the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 will be described with reference to FIGS. FIG. 23 is a timing chart showing the operation of the vertical flap 20, the horizontal flap 30 and the auxiliary flap 130 when the operation is stopped, and FIG. 24 is a flowchart for explaining the control of the indoor control unit 41 when the operation is stopped.

  In the indoor control unit 41, first, as shown in FIG. 24, before the time t41 in FIG. 23, it is determined whether or not an instruction to stop the operation is given from the user or the like, and the operation is automatically stopped. A determination is made as to whether or not (step S41). If there is a stop instruction from a user or the like, the indoor control unit 41 temporarily stops the operations of the vertical flap 20 and the horizontal flap 30 (step S42), and starts the operation after time t41 in FIG. Then, from time t41 to time t46, as shown in FIG. 24, the operation of the horizontal flap 30 and the operations of the vertical flap 20 and the auxiliary flap 130 proceed independently in parallel (steps S43 to S47). ).

  After the time t41 has elapsed (see FIG. 25A), the rack member 57 moves to the rack threshold angle position Pr6 (FIG. 25B). The rack threshold angle position Pr6 is a position provided between the rack upper position Pr3 and the flap rubbing prevention rack position Pr2. Further, when the time t41 has elapsed, in parallel with the movement of the rack member 57, the vertical flap 20 also starts moving toward the wide position. The vertical flap 20 is moved to the wide position by moving the right flap 20b to the right fully open position Pm1 and moving the left flap 20a to the left fully open position Pn3.

  At time t42, in the horizontal flap 30, the rack member 57 reaches the rack threshold angle position Pr6 (step S43), and the link member 58 starts to move toward the fully open position Pl5.

  At time t43, the link member 58 has reached the fully open position Pl5, and origin search is performed (step S44). Further, at time t43, the origin of the vertical flap 20 is determined. At time t43, since the vertical flap 20 has already moved to the wide position, the auxiliary flap 130 moves toward the fully closed position Pa4.

  At time t44, the link member 58 that has finished the origin start to move toward the flap rubbing prevention link position Pl2.

  At time t45, the movement of the link member 58 to the flap rubbing prevention link position P12 is completed, the movement of the auxiliary flap 130 to the fully closed position Pa4 is also completed (step S47), and the auxiliary flap 130 is in the fully closed position. Origin search is performed at Pa4 (see FIG. 25C).

  At time t46, the rack member 57 starts to move from the threshold angle position Pr6 to the flap rubbing prevention rack position Pr2 (see FIG. 25D).

  At time t47, the movement of the rack member 57 to the flap rubbing prevention rack position Pr2 is completed, and the movement of the horizontal flap 30 to the flap rubbing prevention position is completed (step S45). At this time, the indoor control unit 41 detects that the movement of the horizontal flap 30 to the flap rubbing prevention position and the movement of the auxiliary flap 130 to the fully closed position Pa4 are completed, and determines to proceed to the next step. (Step S48).

  At time t <b> 48, the rack member 57 is moved to the fully closed position Pr <b> 1 and the link member 58 is moved to the fully closed position Pl <b> 1 so that the horizontal flap 30 is fully closed, that is, the process of covering the outlet 15 with the horizontal flap 30 is performed. (Step S49). At time t48, the rack member 57 and the link member 58 are tightened (step S50). This retightening gives an instruction that the rack driving motor 51a and the link driving motor 51b further rotate the horizontal flap 30 in the closing direction even when the horizontal flap 30 hits the main body casing 13 and does not close any further. Thus, the horizontal flap 30 is pressed against the main casing 13 by the torque of the rack driving motor 51a and the link driving motor 51b. By this retightening, the horizontal flap 30 closes the air outlet 15 without loosening.

  When the tightening is finished, the operations of the vertical flap 20, the horizontal flap 30, and the auxiliary flap 130 when the operation is stopped are finished. The state after the additional tightening at time t48 is the state shown in FIG. 25 (e), which is the state before the operation start shown in FIG. 8 (a).

(4) Features (4-1)
As described above, in the air conditioning indoor unit 10 according to this embodiment, as shown in FIG. 11, the vertical flap 20 facing the front indicated by the broken line is compared with the auxiliary flap 130. As can be seen, the vertical flap 20 and the auxiliary flap 130 are designed to be large enough to interfere with each other. However, when the operation is stopped, the vertical flap 20 (first flap) is moved to the wide position (first flap storage position) by the indoor control unit 41 (control unit of claim 1). As can be seen from time t48 in FIG. 23, the right flap 20b is in the right fully open position (right flap wide position) Pm1, and the left flap 20a is in the left fully open position (left flap wide position) Pn3. Therefore, even if the auxiliary flap 130 is in the fully closed position Pa4 (second flap storage position) as shown in FIG. 11, the auxiliary flap 130 does not hit the vertical flap 20. Thus, the auxiliary flap 130 can be stored compactly so as not to hit the vertical flap 20. The vertical flap 20 is for controlling the wind direction (first wind direction) in the left-right direction.

  On the other hand, at the start of operation, the auxiliary flap 130 is moved to the non-interference position Pa3 before the vertical flap 20 by the indoor control unit 41 before the time t3 in FIG. 7 or the time t13 in FIG. Steps S4 and S11). Then, after the time t3 or the time t13 when the auxiliary flap 130 completes the movement to the non-interference position Pa3, the vertical flap 20 can freely control the wind direction in the left-right direction without receiving the interference of the auxiliary flap 130. . Therefore, at time t4 and time t14, the vertical flap 20 performs wind direction control and is moved to the memory angular positions Pm2 and Pn2 of the right flap 20b and the left flap 20a of the vertical flap 20 (steps S5 and S12).

  The air conditioning indoor unit 10 is made compact by moving the vertical flap 20 to the wide position and moving the auxiliary flap 130 to the fully closed position Pa4 (second flap storage position) at the back and storing it. This is achieved by moving the auxiliary flap 130 to the non-interference position Pa3 before 20. On the other hand, since the vertical flap 20 and the auxiliary flap 130 are designed to be large enough to interfere with each other, the wind direction control capability of the vertical flap 20 and the auxiliary flap 130 can be improved. As a result, the air conditioning indoor unit 10 can be made compact and the wind direction control capability can be improved.

(4-2)
The horizontal flap 30 is assisted by the auxiliary flap 130 to control the vertical wind direction (second wind direction). As can be seen from the description of FIG. 17 and the like, the horizontal flap 30 controls the second wind direction outside the auxiliary flap 130 during operation.

  For example, as can be seen from the vertical flap 20, horizontal flap 30, and auxiliary flap 130 between time t3 and time t4 in FIG. 7 and between time t13 and time t14 in FIG. At the start, the vertical flap 20 and the horizontal flap 30 are moved simultaneously while maintaining the state where the auxiliary flap 130 is in the non-interference position Pa3. At this time, the vertical flap 20 moves the right flap 20b and the left flap 20a from the right fully opened position Pm1 and the left fully opened position Pn3 to the memory angular positions Pm2 and Pn2, and the horizontal flap 30 has the rack member 57 in the rack rubbing prevention rack position. It has moved from Pr2 to the fully open position Pr5.

  Compared to the case where the indoor control unit 41 can simultaneously move the vertical flap 20 and the horizontal flap 30 with the auxiliary flap 130 in the non-interference position Pa3, and the vertical flap 20 and the horizontal flap 30 must be moved sequentially. Saving travel time. Since the flap movement of the vertical flap 20 and the horizontal flap 30 at the start of operation can be speeded up, the time required to start the wind direction control can be shortened.

(4-3)
For example, from time t22 to time t26 in FIG. 19, the movement of the rack member 57 of the horizontal flap 20 from the rack lower position Pr4 to the rack upper position Pr3, the movement of the link member 58 from the origin to the link memory angular position pl4, and FIG. The indoor control unit 41 includes the movement of the horizontal flap 20 from the rack upper position Pr3 to the rack lower position Pr4 from the time t32 to the time t36, and the movement of the link member 58 from the origin to the link memory angular position pl6. Can change the posture of the horizontal flap 30 while the auxiliary flap 130 is stopped at the non-interference position Pa3 when the wind direction is changed.

  Since the posture of the horizontal flap 30 can be changed without stopping the auxiliary flap 130 at the non-interference position Pa3, the non-interference position is compared with the case where the auxiliary flap 130 is closed and the posture is changed to the horizontal flap 30. The time for moving the auxiliary flap 130 from Pa3 to the closed position (for example, the fully closed position Pa4) can be shortened. In this case, not only the movement time of the auxiliary flap 130 from the non-interference position Pa3 to the fully closed position Pa4 but also the auxiliary flap 130 may interfere with the vertical flap 20, so that the auxiliary flap 130 is moved to the fully closed position. In order to move to Pa4, since the movement of the vertical flap 20 is also accompanied, considerable time is taken. In this manner, the flap movement of the horizontal flap 30 when the wind direction is changed can be speeded up, and the performance of the wind direction control can be improved.

(4-4)
During operation (for example, from time t3 in FIG. 7 or after time t13 in FIG. 14 to time t43 in FIG. 23), the indoor control unit 41 does not move the auxiliary flap 130 inward from the non-interference position Pa3. In addition, the second wind direction is controlled by the auxiliary flap 130 and the vertical flap 20. As described above, when the up / down wind direction (second wind direction) is controlled without moving the auxiliary flap 130 inward of the non-interference position Pa3, the auxiliary flap 130 outside the non-interference position Pa3 is absolutely vertical flap 20. Therefore, the left / right wind direction (first wind direction) can be performed regardless of the posture of the auxiliary flap 130 and the horizontal flap 30. Therefore, it is possible to control the vertical and horizontal wind directions at the same time, and it is possible to speed up the flap movement of the vertical flap 20, the horizontal flap 30 and the auxiliary flap 130 for the wind direction control during operation, and improve the performance of the wind direction control. Can be made.

(4-5)
As shown in FIG. 11, the horizontal flap 30 covers the outlet 15 and closes the outlet 15 when the operation is stopped, and the auxiliary flap 130 is the vertical flap 20 in the main body casing 13 (inside the casing) when the operation is stopped. And the horizontal flap 30. As shown in FIG. 7 and FIG. 14, the indoor control unit 41 has a fully closed position Pa4 that does not hit the horizontal flap 30 that closes the air outlet 15 when the operation is stopped (auxiliary flap storage position (second flap storage position)). )), The auxiliary flap 130 is moved. Since the auxiliary flap 130 is moved to the fully closed position Pa4 and the air outlet 15 can be covered with the horizontal flap 30, the main casing 13 can be further downsized in the type in which the air outlet 15 is covered with the horizontal flap 30.

(4-6)
At time t2 in FIG. 7 and time t12 in FIG. 14, the indoor control unit 41 assists before the auxiliary flap 130 moves from the fully closed position Pa4 (second flap storage position) to the non-interference position Pa3 at the start of operation. Even if the flap 130 is in the non-interference position Pa3, the horizontal flap 30 is moved to a flap rubbing prevention position (third flap operation start position) where the horizontal flap 30 does not hit the auxiliary flap 130. As shown in FIG. 12, the flap rubbing prevention position is a state in which the rack member 57 is in the flap rubbing prevention rack position Pr2 and the link member 58 is in the flap rubbing prevention link position Pl2. Since the horizontal flap 30 is moved to the flap rubbing prevention position before the auxiliary flap 130 reaches the non-interference position Pa3 by the indoor control unit 41, the non-interference position Pa3 is further set outside the position where it hits the closed horizontal flap 30. The air conditioning indoor unit 10 can be made compact when the operation is stopped.

(4-7)
As shown at time t2 in FIG. 7 and time t12 in FIG. 14, the indoor control unit 41 operates when the horizontal flap 30 is moved to the flap rubbing prevention position (third flap operation start position) (FIG. 18), the origin of the auxiliary flap 130 is determined based on the angle of the auxiliary flap 130 at the fully closed position Pa4 (predetermined angle on the closing side). When operated in this way, the origin of the auxiliary flap 130 can be determined in parallel with the movement of the horizontal flap 30, so that the time until the completion of the origin of the auxiliary flap 130 can be shortened and the start of wind direction control is started. Can be shortened.

(4-8)
The horizontal flap 30 has a rotating shaft 310 that connects the front connecting portions 311, 312, and 313 whose axial direction is arranged substantially parallel to the air outlet. The rotary shaft 310 is configured to be movable, and the indoor control unit 41 moves the horizontal flap 30 to the flap rubbing prevention position (third flap operation start position) by moving the rotary shaft 310 to a predetermined position by the rack member 57. Let me. Since the horizontal flap 30 can be provided with a flap rubbing prevention position by the simple configuration of the rotary shaft 310 that can be moved by the rack member 57, the configuration is simplified, and a compact air conditioning indoor unit having high wind direction control capability can be provided at low cost. .

(4-9)
When the operation is stopped at time t45 in FIG. 23, the indoor control unit 41 causes the auxiliary flap 130 to return to the origin at the fully closed position Pa4 (second flap storage position). In this manner, in the air conditioning indoor unit 10, since the origin of the auxiliary flap 130 is obtained when the operation is started, the origin of the auxiliary flap 130 is obtained when the operation is started, and thus the auxiliary to the non-interference position Pa3 is performed. Since the movement of the flap 130 can be performed quickly and the operation can be started smoothly, the operation start time can be shortened.

(4-10)
The horizontal flap 30 is configured to be movable to an origin position where the origin can be obtained without the horizontal flap 30 hitting the auxiliary flap 130 when the auxiliary flap 130 is in the non-interference position Pa3. At time t4 in FIG. 7, the origin of the rack member 57 is performed, and at time t7, the origin of the link member 58 is performed, and the origin of the horizontal flap 30 is performed by these two operations. Further, at time t14 in FIG. 14, the origin of the rack member 57 is performed, and at time t17, the origin of the link member 58 is performed, and the origin of the horizontal flap 30 is performed by these two operations.

  In this way, the indoor control unit 41 moves the auxiliary flap 130 to the non-interference position Pa3 and then moves the horizontal flap 30 to the origin position, and causes the horizontal flap 30 to perform origin origin. When the horizontal flap 30 is operated at the position on the link, the fully open position Pr5 and the fully open position Pl5 shown in FIG. 7 become the origin position. When the horizontal flap 30 is operated at the link lower position, the fully open position Pr5 and the fully closed mechanism limit position Pl8 shown in FIG. 14 become the origin position. At the origin position of the horizontal flap 30, the angle of the vertical flap 20 is changed between time t3 and time t4 in FIG. 7 and between time t13 and time t14 in FIG. 14 regardless of the origin of the horizontal flap 30. The time until the wind direction control of the vertical flap 20 can be shortened.

(4-11)
When the auxiliary flap 130 is in the non-interference position Pa3 during operation, the indoor control unit 41 controls the horizontal flap 30 so that the horizontal flap 30 controls the vertical wind direction (second wind direction) only by the operation that does not hit the auxiliary flap 130. To control. By moving the auxiliary flap 130 to the non-interference position Pa3, all the operations of the horizontal flap 30 during operation can be performed. Therefore, the vertical flap 20 can also control the wind direction regardless of the operation of the horizontal flap 30 during operation. it can. Thereby, in the structure provided with the vertical flap 20, the auxiliary | assistant flap 130, and the horizontal flap 30, the capability of wind direction control can be improved.
