JP 2006-138629 A

  In the above, the panel is directly connected to the arm portion. In other words, the panel is directly attached to the driving means for driving the panel via the shaft. Therefore, the panel is not easily detached from the shaft.

  By the way, it is preferable that the panel can be removed for cleaning and maintenance. However, when the panel is directly attached to the driving means, it is difficult to attach or detach the panel. If the panel is easily removed, the fitting with the shaft becomes insufficient when the panel is mounted, and the panel may not be opened and closed smoothly.

  That is, as long as the panel is directly attached to the driving means, the above problem cannot be avoided. In view of the above, the present invention has an object to provide an air conditioner that can be easily attached and detached and that can maintain the reliability of the opening and closing operation.

The present invention is a curved surface toward the bottom surface from the front of the cabinet, the air outlet is formed in a curved surface, a part of the cabinet, is a wind guide panel for guiding air from the air outlet into the room space, the wind guide panel The upper and lower shafts can be opened in both directions by rotating in different directions around the upper and lower axes, and a support material for detachably supporting the wind guide panel is provided, and the upper and lower shafts are provided on the support material. An open / close mechanism is provided to move the support material with the air guide panel attached to open and close the open / close mechanism, and the open / close mechanism has a rod that is taken in and out of the cabinet, and is connected to the rod without the support material coming off. When the rod moves the support member, the support member to which the wind guide panel is attached rotates about the upper shaft or the lower shaft in different directions, and the wind guide panel is opened and closed.

  The wind guide panel is connected to the opening / closing mechanism via a support member. When the wind guide panel is opened and closed, it is opened and closed together with the support material. And since a wind guide panel is attached or detached with respect to a support material, it is not attached or detached directly from an opening-and-closing mechanism.

  The wind guide panel is supported by at least two points on the support member in the vertical direction. Even if the support at one point is released, the wind guide panel is preferably supported at another point. When attaching and detaching, since the wind guide panel is supported by the support material at at least one point, the wind guide panel can be prevented from falling during the attaching and detaching work.

  It is preferable that one of the wind guide panel or the support member is provided with a locking portion for locking the other, and a holding portion for rotatably holding the wind guide panel with respect to the support member is provided. When the locking by the locking part is released, the wind guide panel is hung on the support material by the holding part. As described above, the wind guide panel is detached from the support material, but is not dropped because it is supported at one point by the holding portion.

  It is preferable that the holding part is positioned above the locking part in the wind guide panel. When the locking by the locking portion on the lower side is released, the lower side of the wind guide panel is detached from the support material. However, since the upper side of the wind guide panel is supported by the support member, the wind guide panel hangs on the support member. At this time, since the cabinet has a curved surface, the air outlet is exposed to the outside, and the air outlet can be cleaned without completely removing the air guide panel from the support member.

  The wind guide panel is provided with a locking portion, and the locking portion includes a movable movable member that presses the support material. It is preferable that a part of the movable member is exposed on the outer surface of the wind guide panel, and the movable member is moved by an operation from the outside to release the support material. Thereby, a movable member can be moved from the outer side of a wind guide panel. Even in the closed position where the wind guide panel is closed, the lock is released by an external operation, and the wind guide panel can be easily detached from the support material.

  It is preferable that the movable member is movably supported by the wind guide panel and the movement of the movable member is restricted so that the movable member does not come off the wind guide panel. When operated from the outside, the movable member can be prevented from moving too much, and the movable member can be prevented from coming off the wind guide panel.

  The holding portion includes a rotation shaft provided on one of the wind guide panel or the support material and a bearing provided on the other. It is preferable that the wind guide panel is supported by the support member even when the locking is released by fitting the rotation shaft to the bearing. By removing the pivot shaft from the bearing, the wind guide panel can be completely removed from the support material.

  According to the present invention, the air guide panel does not have to be directly attached to and detached from the opening / closing mechanism, and the support member is not removed from the cabinet, so that the connection between the opening / closing mechanism and the supporting member is not disconnected, and the opening / closing operation is performed. Can be kept reliable.

  The indoor unit of the air conditioner of this embodiment is shown in FIGS. The indoor unit includes a heat exchanger 1 and an indoor fan 2, which are housed in a cabinet 3. The cabinet 3 is formed in a box shape having a depth longer than the height, and has a curved surface from the front surface to the bottom surface. A suction port 4 is formed on the upper surface of the cabinet 3, and an outlet 5 is formed on the curved surface.

  An air passage 6 extending from the suction port 4 to the blowout port 5 is formed inside the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are disposed in the air passage 6. A filter 7 is disposed between the suction port 5 and the heat exchanger 1 to remove dust from the indoor air sucked from the suction port 4. A cleaning device 8 for cleaning the filter 7 is provided.

  The cleaning device 8 moves the filter 7 in the cabinet 3 to pass through the dust removing unit 9, and the dust removing unit 9 removes dust attached to the filter 7. A guide path 10 that is curved in a U shape in a side view is formed on the front side in the cabinet 3, and a moving unit including a motor and a gear reciprocates the filter 7 along the guide path 10. In the dust removing unit 9, the rotating brush 11 scrapes off dust from the passing filter 7, and a suction fan causes air to flow in a direction substantially parallel to the filter 7 (left and right direction), and the scraped dust is sucked and discharged. To do.

  An air guide panel 20 that opens and closes the air outlet 5 is provided on the curved surface of the cabinet 3. As shown in FIGS. 3 to 6, the wind guide panel 20 can be opened both vertically and an opening / closing mechanism for opening and closing the wind guide panel 20 is provided.

  In the air conditioner, an outdoor unit (not shown) is installed outside the indoor unit. The outdoor unit includes a compressor, a heat exchanger, a four-way valve, an outdoor fan, and the like, and a refrigeration cycle 40 is formed by these and the indoor heat exchanger 1. And as shown in FIG. 7, the control apparatus 41 which controls the refrigerating cycle 40 is provided in an indoor unit. A control device 41 composed of a microcomputer controls the refrigeration cycle 40 based on a user instruction and detection signals of various sensors 42 such as a temperature sensor that detects a room temperature and an outside air temperature, and performs an air conditioning operation. At this time, the control device 41 controls the opening / closing mechanism according to the cooling / heating operation to open / close the wind guide panel 20. Further, the control device 41 cleans the filter 7 by controlling the cleaning device 8 periodically or in accordance with an instruction from the user.

  The wind guide panel 20 is formed by a single curved panel, and the width of the wind guide panel 20 is the same as the width of the cabinet 3 and is larger than the width of the outlet 5. And the front panel 21 is formed in the front surface of the cabinet 3 so that it may become one step lower from the middle part of the front surface to the bottom surface. Thereby, a recessed part is formed in the whole width direction, and the wind guide panel 20 fits into the recessed part. An opening is formed in the front panel 21 that forms the recess, and this opening is the air outlet 5. Therefore, the wind guide panel 20 is positioned in front of the air outlet 5 and covers the air outlet 5 and the front panel 21 around the air outlet 5. At this time, the wind guide panel 20 is in the closed position shown in FIG.

  When in the closed posture, a gap is formed between the front end and rear end of the wind guide panel 20 and the cabinet 3. As shown in FIGS. 4 and 6, when the wind guide panel 20 opens and closes, the end of the wind guide panel 20 enters the gap. The wind guide panel 20 can rotate smoothly without hitting the cabinet 3. Further, when the wind guide panel 20 is opened to the maximum in the upper opening or the lower opening, the front and rear ends of the wind guide panel 20 are formed so that the wind guide panel 20 contacts the cabinet 3. Prevents the wind from leaking. In particular, in the case of cold air, condensation on the bottom surface side of the cabinet 3 can be prevented.

  Thus, the outer surface of the wind guide panel 20 constitutes a smooth curved surface extending from the front surface to the bottom surface of the cabinet 3. That is, the wind guide panel 20 is a member constituting a part of the front surface of the cabinet 3. In other words, a part of the panel of the cabinet 3 is used as the wind guide panel 20. Thereby, the wind guide panel 20 becomes a long panel having a long overall length as compared with the louver employed in the conventional air conditioner.

  The wind guide panel 20 opens in either the upper or lower direction by rotating in different directions around the upper and lower axes. As shown in FIGS. 5 and 6, the wind guide panel 20 opens downward around the lower shaft 22 during the cooling operation. In this downward opening posture, the wind guide panel 20 is connected to the lower wall of the air outlet 5, and a long nozzle is formed by the air guide panel 20 and the upper wall of the air outlet 5. The wind guide panel 20 guides the cool air obliquely upward, and the cool air blows out along the ceiling.

  As shown in FIGS. 3 and 4, it opens upward around the upper shaft 23 during heating operation. In this upward-opening posture, the air guide panel 20 shields the front of the air outlet 5, suppresses the warm air blown forward, and guides the warm air toward the floor surface. Even at the initial stage of the cooling operation, the air guide panel 20 is in the upwardly open posture, and the cool air is blown out in the direction of the floor surface to perform rapid cooling. As shown in FIG. 2, the wind guide panel 20 is closed when the operation is stopped, covers the air outlet 5, and is integrated with the cabinet 3.

  By the way, in the wind guide panel 20 enlarged as described above, twisting and bending are likely to occur. Therefore, on the inner surface of the wind guide panel 20, reinforcing peripheral walls are formed at both end edges on the front-rear direction (short direction) side. A peripheral wall is formed over the whole left-right direction (longitudinal direction). The peripheral wall has a hollow structure and can be thick. With such a peripheral wall, the strength of the wind guide panel 20 can be increased and bending can be prevented. Further, similar reinforcing peripheral walls are also formed at both end edges on the left and right direction sides. Therefore, twisting of the wind guide panel 20 can be prevented.

  In this way, by strengthening the four edges of the wind guide panel 20 by increasing the thickness, the strength against deformation of the wind guide panel 20 can be increased, and the size of the wind guide panel 20 can be increased. Moreover, since the wind guide panel 20 has a structure that is not easily deformed, it is possible to increase the degree of bending of the wind guide panel 20 in the front-rear direction, and it is easy to control the air blowing direction when the wind guide panel 20 is opened. . That is, during the cooling operation, the cool air can be guided toward the ceiling, and the reach distance of the cool air can be increased. During heating operation, warm air is guided toward the wall, and the warm air reaches the floor.

  In addition, an inclined surface is formed on the distal end side of the peripheral wall. The inner surface of the peripheral wall is an inclined surface. The outer surface is a vertical surface. When the wind guide panel 20 is in the downward opening posture, the blown cold air may hit the peripheral wall located in the left-right direction, and dew may be attached to the peripheral wall. Therefore, by using the inclined surface, the cold air flows along the inclined surface. The cold air flows without stopping and can prevent condensation on the surrounding wall.

  A heat insulating material 30 is provided on the inner surface of the wind guide panel 20 surrounded by the peripheral wall. The heat insulating material 30 is attached over the entire surface except for both end sides in the left-right direction. The width in the left-right direction of the heat insulating material 30 is set to be larger than the width of the air outlet 5. The surface of the heat insulating material 30 is flush. Therefore, there is no protrusion on the inner surface side of the air guide panel 20 facing the air outlet 5, and the flow of the wind is not hindered.

  As shown in FIG. 5, support materials 31 are provided on both sides of the inner surface of the wind guide panel 20 in the left-right direction. The wind guide panel 20 is detachably supported by the support member 31. The support material 31 is attached to the cabinet 3 via a rod 32. That is, the air guide panel 20 is attached to the cabinet 3 via the rod 32 constituting the opening / closing mechanism, and is attachable to and detachable from the cabinet 3.

  The upper shaft 23 of the wind guide panel 20 is provided on the front side of the support material 31, and the lower shaft 22 is provided on the rear side of the support material 31. The vertical shafts 22 and 23 are arranged along the left-right direction, and both ends are supported so as to be separated from the support material 31. The vertical shafts 22 and 23 are located outside the blower outlet 5 and in front of the blower outlet 5 in the front / rear and left / right directions. Therefore, the vertical shafts 22 and 23 do not disturb the flow of the wind blown out from the air outlet 5.

  Locking portions for locking the support material 31 are provided on both sides of the wind guide panel 20 in the left-right direction. As the locking portion, a claw 33 that is slidable in the left-right direction is provided. The claw 33 is opposed to the peripheral wall formed in the front-rear direction and is urged toward the peripheral wall by an urging member such as a spring. The support material 31 is locked to the wind guide panel 20 by the support material 31 being sandwiched between the claw 33 and the peripheral wall. The wind guide panel 20 can be removed from the support member 31 by sliding the claw 33 in the direction away from the peripheral wall.

  In the front-rear direction, the claw 33 may be provided on at least one of the front side and the rear side. In this case, on the other side, a holding portion for holding the wind guide panel 20 rotatably is provided. As a holding part, the wind guide panel 20 is rotatably held by engaging a pin with the hole. A pin is provided on either the wind guide panel 20 or the support material 31, and a hole for receiving the pin is formed on the other. By fitting the pin into the hole, the support member 31 holds the wind guide panel 20 so as to be rotatable. Thus, the wind guide panel 20 is supported by the support material 31 at two points in the front-rear direction.

  When the claw 33 is provided on one side, the claw 33 is preferably provided on the front side in consideration of workability. In this case, the user can attach and detach the wind guide panel 20 while looking at the nail 33 in a state where the wind guide panel 20 is in the downward opening posture. Therefore, the attaching / detaching work can be easily and reliably performed. Further, even when the claw 33 is released, the pin remains fitted in the hole, so that the wind guide panel 20 is rotatably supported by the support member 31 and the wind guide panel 20 is suspended from the support member 31. It becomes a state. Therefore, the wind guide panel 20 does not fall. Thereafter, when the pin is removed from the hole, the air guide panel 20 can be completely removed from the support member 31.

  In the panel structure described above, since the claw 33 is provided on the inner surface side of the wind guide panel 20, it is necessary to remove the wind guide panel 20 with the lower opening posture or the upper opening posture. Therefore, a panel structure that can be attached and detached even when the air guide panel 20 is in the closed position is not necessarily required to be in the downward opening position or the upward opening position. Below, this panel structure is demonstrated.

  In this panel structure, as shown in FIG. 8, locking portions 300 for locking the support member 31 are provided on both sides of the air guide panel 20 in the left-right direction. In addition, a holding portion 301 that holds the air guide panel 20 with respect to the support member 31 is provided. The rear side of the wind guide panel 20 is supported by the locking part 300, the front side of the wind guide panel 20 is supported by the holding part 301, and the wind guide panel 20 is supported by the support material 31 at two points. That is, when the wind guide panel 20 is in the closed posture, the holding unit 301 is positioned above the locking unit 300. In FIG. 8, the upper side of the drawing is the front side of the wind guide panel 20, and the lower side is the rear side of the wind guide panel 20.

  The locking portion 300 includes a movable member 302 that presses the support material 31. As shown in FIGS. 9 to 12, the movable member 302 is provided on the inner surface side of the wind guide panel 20 so as to be slidable in the left-right direction. The movable member 302 has a claw 303 on the inner end side, that is, on the end side closer to the center of the wind guide panel 20, and has an operation button 304 on the outer end side, that is, the end side closer to the outer side of the wind guide panel 20. . The claw 303 and the operation button 304 are integrally connected by the connecting plate 305. The connecting plate 305 is located on the back side of the support material 31.

  The claw 303 engages the support material 31 so as to sandwich the front and back surfaces of the support material 31. A locking piece 306 projects from the inner end side of the support member 31, that is, the end side closer to the center of the air guide panel 20, and the claw 303 is engaged with the locking piece 306. A pin 307 projects from the inner end side of the claw 303, and the pin 307 is inserted into a holding hole 309 formed in the vertical wall 308 erected on the air guide panel 20. A spring 310 is inserted around the pin 307, and the spring 310 is interposed between the vertical wall 308 and the claw 303. The spring 310 is covered with a cover piece 311 so as not to be touched from the outside.

  The spring 310 urges the claw 303 toward the outer end side. By providing an urging member such as the spring 310, the claw 303 is pushed toward the support material 31, and the claw 303 locks the support material 31. Therefore, when the wind guide panel 20 opens and closes, the locking of the support material 31 can be maintained, and the wind guide panel 20 can be prevented from being detached from the support material 31. The urging member may be a member having elasticity, and elastic rubber may be used. The support member 31 is positioned on the inner surface of the wind guide panel 20 so as not to move in the left-right direction. Therefore, even if the claw 303 is urged by the spring 310 and comes into contact with the support material 31, the support material 31 does not shift outward.

  As shown in FIGS. 13 and 14, the operation button 304 is inserted into a through hole 321 formed in the peripheral wall 320 on the left and right direction side of the wind guide panel 20. As shown in FIG. 11, the operation button 304 is exposed from the through hole 321 to the outer surface of the wind guide panel 20 by the biasing force of the spring 303. Thereby, the movable member 302 can be operated from the outside.

As shown in FIGS. 10 and 12, when the user performs an operation of pushing the operation button 304, the movable member 302 moves to the longitudinal center side of the wind guide panel 20 against the urging force of the spring 310. Along with this, the claw 303 moves and the locking of the support material 31 is released.
When the wind guide panel 20 is removed from the support member 31, the movable member 302 moves to the outer end side by the spring 310. A step 322 is formed on the outer periphery of the operation button 304, and when the operation button 304 moves outward, the step 322 comes into contact with the inner periphery of the through hole 321. As a result, as shown in FIG. 11, even when the movable member 302 is urged and pushed by the spring 310, the operation button 304 can be prevented from protruding greatly from the outer surface of the wind guide panel 20.

  The movable member 302 is movably held by the wind guide panel 20 in the left-right direction (longitudinal direction of the wind guide panel 20). That is, on the outer end side, the operation button 304 is fitted in the through hole 321, and on the inner end side, the pin 307 is fitted in the holding hole 309. Thereby, the movable member 302 is held by the wind guide panel 20 on both sides in the left-right direction and is not detached from the wind guide panel 20.

  When the operation button 304 is pressed, the movable member 302 moves inward, but this movement is restricted. A rib 323 protrudes from the wind guide panel 20, and the movable member 302 comes into contact with the rib 323 to restrict movement. A slit 324 is formed in the connecting plate 305 of the movable member 302, and a thin piece 325 is formed protruding from the slit 324. The thin piece 325 is thinner than the connecting plate 305. When the thin piece 325 comes into contact with the rib 323, the movement of the movable member 302 is stopped. At this time, the operation button 304 does not come out of the through hole 321 as shown in FIG. Since the pin 307 is fitted in the holding hole 309, the movable member 302 cannot be removed from the wind guide panel 20.

  Here, in order to attach the movable member 302 to the wind guide panel 20, the hole wall of the holding hole 309 is formed in a tapered shape, and the pin 307 of the movable member 302 can be inserted into the holding hole 309 obliquely from above. After the pin 307 is inserted into the holding hole 309, the movable member 302 is pushed down, and the movable member 302 is moved toward the inner end side so that the operation button 304 does not hit the peripheral wall 320. At this time, the thin piece 325 contacts the rib 323. Since the thin piece 325 is thin, the thin piece 325 is easily bent and can be pushed down by hitting the rib 323 until the connecting plate 305 hits the wind guide panel 20. Then, due to the biasing force of the spring 310, the movable member 302 moves to the outer end side, and the operation button 304 is fitted in the through hole 321.

  As shown in FIG. 8, the wind guide panel 20 and the support material 31 are rotatably engaged by a holding portion 301 configured by a rotation shaft 330 and a bearing 331. As shown in FIGS. 15 and 16, a rotating shaft 330 is projected from the front side of the support member 31. The rotation shaft 330 is provided as a pair of left and right. In the figure, reference numeral 80 denotes a support shaft for rotatably mounting the rod 32. 15 and 16, the upper side of the drawing is the front side of the support material 31.

  As shown in FIGS. 13 and 14, a pair of bearings 331 are provided on the front side of the wind guide panel 20. The bearing 331 receives the rotation shaft 330 so that the rotation shaft 330 does not come off. 13 and 14, the upper side of the drawing is the front side of the wind guide panel 20, and the lower side is the rear side of the wind guide panel 20.

  When the wind guide panel 20 is in the closed posture, as will be described later, the upper shaft 23 and the lower shaft 22 of the support member 31 are locked by the opening / closing mechanism, and the support member 31 is held in a state of being close to the cabinet 3. . When the user presses the operation button 304 in the closed wind guide panel 20, the movable member 302 slides and the claw 303 moves away from the support material 31. The engagement between the wind guide panel 20 and the support member 31 is released, and the rear side of the wind guide panel 20 is separated from the support member 31. Since the bearing 331 of the wind guide panel 20 is engaged with the rotation shaft 330 of the support member 31 on the front side of the wind guide panel 20, the wind guide panel 20 is suspended from the support member 31 as shown in FIG. 17. It becomes a state. Therefore, the wind guide panel 20 does not fall during the attaching / detaching operation. In this state, since the blower outlet 5 of the cabinet 3 is exposed to the outside, cleaning and maintenance inside the blower outlet 5 can be performed. Further, when the wind guide panel 20 is lifted and the bearing 331 is removed from the rotating shaft 330, the wind guide panel 20 can be completely removed from the support material 31 held in the cabinet 3.

  Thus, when the locking part 300 is on the rear side, that is, the lower side of the holding part 301, the operation button 304 is close to the floor. Therefore, the user can easily perform an operation for attachment / detachment. Since the wind guide panel 20 is in a suspended state, it does not get in the way of simple work.

  When attaching the wind guide panel 20, first, the bearing 331 of the wind guide panel 20 is hooked on the rotation shaft 330 of the support member 31. As shown in FIG. 17, the front side of the wind guide panel 20 is supported by the support material 31. The wind guide panel 20 can be rotated around the rotation shaft 330. While pushing the operation button 304, the rear side of the wind guide panel 20 is lifted to rotate the wind guide panel 20 counterclockwise.

  When the wind guide panel 20 contacts the support member 31, the operation button 304 is released. The movable member 302 is moved by the biasing force of the spring 310, and the claw 303 sandwiches the support material 31. The rear side of the wind guide panel 20 is supported by the support material 31, and the wind guide panel 20 is attached to the support material 31. Thus, when the wind guide panel 20 is in the closed position, the wind guide panel 20 can be attached and detached. Even when the wind guide panel 20 is in the upward opening posture or the downward opening posture, the wind guide panel 20 can be similarly attached to and detached from the support member 31.

  As shown in FIGS. 11 and 12, the upper surface of the claw 303 is formed as an inclined surface. The lower corner of the inner end side of the support member 31 is rounded. Thereby, the air guide panel 20 can be attached to the support member 31 without pressing the operation button 304.

  When the support member 31 is not present, the movable member 302 is pushed toward the outside of the wind guide panel 20 by the biasing force of the spring 310, and the step 322 comes into contact with the peripheral edge of the through hole 321 as shown in FIG. It is in a position where the support member 31 can be locked. When the rear side of the wind guide panel 20 is rotated counterclockwise about the rotation shaft 330, the claw 303 hits the lower corner of the support member 31. If it rotates as it is, the movable member 302 will be pushed by the support material 31, and will move toward a center side. The lower corner of the support member 31 gets over the inclined surface of the claw 303. Due to the urging force of the spring 310, the movable member 302 moves outward, and the claw 303 locks the support material 31. In this way, the wind guide panel 20 can be attached to the support member 31 without pressing the operation button 304, and the wind guide panel 20 can be mounted more easily.

  In the attaching / detaching operation of the air guide panel 20, the user can perform the operation without touching the support material 31. That is, the user has only the outside in the left-right direction of the wind guide panel 20 and can operate the operation button 304 as necessary, and can easily attach and detach the wind guide panel 20. Further, the wind guide panel 20 is not a structure directly attached to the opening / closing mechanism, but a structure attached via the support member 31. Therefore, when the wind guide panel 20 is attached or detached, there is no influence on the opening / closing mechanism, and the possibility of the opening / closing operation failure of the wind guide panel 20 due to a mounting error at the time of mounting or the like can be reduced.

  As shown in FIGS. 18 to 21, the air outlet 5 is provided with a wind direction plate 24 and an auxiliary louver 800. The wind direction plate 24 changes the wind direction in the left-right direction by changing the angle in the left-right direction. The auxiliary louver 800 is provided at the outlet portion of the outlet 5 in front of the wind direction plate 4 and changes the angle in the vertical direction according to the attitude of the wind guide panel 20 to adjust the vertical wind direction while rectifying the blown wind. Change.

  The auxiliary louver 800 is formed in a plate shape that is long in the left-right direction, and the front and rear ends are tapered. On the rear end side, a rotating shaft 801 having an axial direction in the left-right direction is fixed to a shaft connecting portion formed in the left and right end portions. The rotary shaft 801 is disposed on the upper wall 5a side of the upper and lower walls 5a and 5b forming the air passage 6 leading to the blower outlet 5, and is rotatably supported through the left and right side walls of the blower outlet 5. The A louver motor 803 is connected to the shaft end of the rotating shaft 801 via a speed reduction mechanism (not shown) (see FIG. 7), and the louver motor 803 is driven and controlled by the control device 41.

  The control device 41 sets the louver motor 803 so that the auxiliary louver 800 is oriented at an angle with respect to the flow of the wind so as to change the wind direction in an upward opening posture in which the lower end of the wind guide panel 20 is opened forward around the upper shaft 23. Drive control. Further, the control device 41 drives and controls the louver motor 803 so as to control the orientation of the auxiliary louver 800 in parallel with the wind flow in the downward opening posture in which the upper end of the wind guide panel 20 is opened downward about the lower shaft 22.

  Further, the control device 41 is configured so that the air guide panel 20 is in the upwardly open posture, the front of the air outlet 5 is shielded by the auxiliary louver 800, and the air blown toward the front is pressed and guided downward. Control attitude. In addition, the angle of the auxiliary louver 800 is controlled so that the wind direction is changed in two steps by applying the wind blown from the outlet 5 to the two members of the auxiliary louver 800 and the wind guide panel 20 in the upward opening posture of the wind guide panel 20. To do. Below, the attitude | position of the wind guide panel 20 and the auxiliary louver 800 is illustrated.

  FIG. 4 shows an example in which the wind guide panel is in an upwardly open posture and the auxiliary louver 800 is oriented at an angle with respect to the wind flow. In this example, the air blown out from the outlet 5 causes the auxiliary louver 800 to have an angle with respect to the flow of the wind, so that the wind is rectified by the auxiliary louver 800, and part of the air is below the auxiliary louver 800. It flows directly diagonally downward without interfering with the wind guide panel 20. The remaining wind is rectified by the auxiliary louver 800 and then hits the inner surface of the wind guide panel 20 and is guided obliquely downward along the inner curved surface.

  FIG. 6 shows an example in which the wind guide panel is in the downward opening posture and the auxiliary louver 800 is oriented parallel to the wind flow. In this example, the wind guide panel 20 rotates downward about the lower shaft 22 and takes a substantially horizontal posture. That is, the wind guide panel 20 is connected to the lower wall of the air outlet 5 when in the downward opening posture, and a long nozzle is formed by the air guide panel 20 and the upper wall 5a of the air outlet 5. Therefore, the wind guide panel 20 can guide the wind diagonally upward and blow it out to the far side along the ceiling. At this time, since the auxiliary louver 800 is oriented in parallel with the wind flow, the auxiliary louver 800 acts to guide the air blown from the outlet 5 far away without forcibly blocking the wind flow.

  FIG. 18 shows an example in which the opening angle of the wind guide panel 20 is suppressed to a substantially vertical posture in the upward opening posture of the wind guide panel, and the auxiliary louver 800 is rectified with an angle with respect to the wind flow. In this example, the air blown out from the blowout port 5 is rectified by the auxiliary louver 800, hits the wind guide panel 20, changes the wind direction, and wind flows from the blowout port 5 in the direction directly below. Therefore, in this example, the air is blown directly under the outlet 5 by the change in the wind direction in two stages, that is, the change in the wind direction by the auxiliary louver 800 and the change in the wind direction by the wind guide panel 20 located on the downstream side of the wind. Further, since the wind direction is changed step by step by the auxiliary louver 800 and the wind guide panel 20, wind noise can be reduced as compared with the extreme change in the wind direction.

  In FIG. 19, the opening direction of the wind guide panel 20 is suppressed to an almost vertical posture in the upward opening posture of the wind guide panel, but the auxiliary louver 800 is oriented in the vertical direction so that the auxiliary wind louver 800 performs the main wind direction changing function. This is an example in which the flow of wind is blocked and the wind is pressed downward. In this example, the function of changing the wind direction is exhibited mainly by the auxiliary louver 800, and the wind flow is slightly lower than the flow of the wind directly below the vertical direction shown in FIG.

  FIG. 20 is an example in which the wind guide panel 20 is opened to the maximum with the wind guide panel in the upwardly opened posture, and the auxiliary louver 800 is oriented at an angle with respect to the wind flow, as in the posture shown in FIG. . In this example, since the auxiliary louver 800 is provided so as to be rotatable around the shaft 801 in the vicinity of the outlet of the air outlet 5 in order to change the wind direction, the auxiliary louver 800 is provided between the auxiliary louver 800 and the upper wall 5a of the air outlet 5. There is a possibility that a space 804 is generated, and an air flow along the upper wall 5a is generated through the space 804. Air leaks, and a part of the air hits the wind guide panel 20 and escapes in the left-right direction.

  Therefore, in order to eliminate such air leakage, as shown in FIG. 20, the air flow from the air passage 6 is separated from the upper wall 5a on the front side of the shaft 801 of the auxiliary louver 800 to the upper wall 5a. A protrusion 901 is formed to follow the auxiliary louver 800. The protrusion 901 has a triangular cross section, but may have another shape such as a semicircular cross section. By this protrusion 901, the air flow along the upper wall 5a can jump along the auxiliary louver 800 side by the protrusion 901.

  As shown in FIG. 21, the opening / closing mechanism of the wind guide panel 20 includes a moving unit 50 that moves the wind guide panel 20 close to and away from the cabinet 3, and a direction in which the wind guide panel 20 opens when the wind guide panel 20 moves. And a regulation unit 51 that regulates the above.

  When opening the wind guide panel 20, the moving unit 50 moves the wind guide panel 20 in a direction away from the cabinet 3. At this time, the restricting portion 51 allows the opening of either the upper opening or the lower opening and restricts the opening of the other to switch the opening direction of the wind guide panel 20. When the downward opening is restricted, the wind guide panel 20 opens upward. Conversely, when the upward opening is restricted, the wind guide panel 20 opens downward. When closing the wind guide panel 20, the moving unit 50 moves the wind guide panel 20 in a direction approaching the cabinet 3.

  That is, the restricting portion 51 restricts the opening direction by locking the upper shaft 23 or the lower shaft 22 so as not to move. When opening downward, the lower shaft 22 is locked. When opening upward, the upper shaft 23 is locked.

  Further, the restricting portion 51 has a function of holding the wind guide panel 20 in a closed posture. The closed wind guide panel 20 is close to the front panel 21 of the cabinet 3. At this time, the restricting portion 51 locks the upper shaft 23 and the lower shaft 22. Even if an external force is applied to pull the wind guide panel 20 apart, the wind guide panel 20 does not move because the shafts 22 and 23 are locked.

  As described above, a drive source only for moving the wind guide panel 20 may be provided as a drive source for opening and closing the wind guide panel 20. In addition, the drive source may be one that causes the wind guide panel 20 to perform a simple operation such as reciprocation. Therefore, the moving unit 50 for reciprocating the wind guide panel 20 can be a simple mechanism. Thereby, the opening / closing mechanism can be simplified, and the opening / closing mechanism can be downsized.

  As shown in FIGS. 22 and 23, the restricting portion 51 restricts the operation of the pair of upper and lower hooks 52 and 53 that hold the upper and lower shafts 22 and 23, and switches the opening direction by switching the opening direction. An interlocking unit 55 that operates the hooks 52 and 53 in an interlocked manner and a drive unit 56 that drives the interlocking unit 55 are provided. 24 to 26, the moving unit 50 includes a rod 32 that holds the wind guide panel 20, a moving mechanism unit 57 that moves the rod 32 in and out of the cabinet 3, and a driving unit 58 that drives the moving mechanism unit 57. 21 and 24 to 26, the auxiliary louver is omitted in order to make the mechanism of the moving part and the restricting part of the wind guide panel easier to understand.

  The restricting portions 51 are provided in a pair of left and right inside the cabinet 3 and are disposed on the outer side in the left-right direction with respect to the air outlet 5. As shown in FIG. 27, the restricting portion 51 is configured on the base plate 60 and unitized. The base plate 60 is fixed inside the cabinet 3.

  The upper hook 52 and the lower hook 53 are rotatably supported by a fixed shaft 61 fixed to the base plate 60. The front panel 21 is formed with doorways 21a in which the hooks 52 and 53 appear and disappear, respectively. The upper hook 52 projects from the doorway 21a and hooks the upper shaft 23 from the lower side. The upper shaft 23 is sandwiched and held by the cradle 62 and the upper hook 52 formed on the front panel 21. Similarly, the lower hook 53 protrudes from the doorway, hooks the lower shaft 22 from the lower side, and sandwiches and holds the lower shaft 22 between the lower hook 53 and the receiving base 63.

  The interlocking unit 55 enables the hooks 52 and 53 to operate using a link mechanism. Specifically, the interlocking portion 55 includes a pair of upper and lower link members 64 and 65 and an interlocking plate 66. The upper and lower link members 64 and 65 connect the upper and lower hooks 52 and 53 and the interlocking plate 66, respectively. That is, a shaft 64 a is formed at one end of the upper link member 64, and the one end shaft 64 a is fitted into the shaft hole of the upper hook 52. The upper hook 52 is rotatably supported at one end of the upper link member 64. The same applies to the lower link member 65 and the lower hook 53.

  The other end of the upper link member 64 is rotatably attached to the interlocking plate 66. The interlocking plate 66 is a sector gear, and teeth are formed on its arc surface. The interlocking plate 66 is rotatably supported by a fixed shaft 67 protruding from the base plate 60. A pair of long grooves 68 are formed in the interlocking plate 66, and the other end shafts 64 b and 65 b of the upper and lower link members 64 and 65 are fitted into the long grooves 68. Each long groove 68 extends in the radial direction about the fixed shaft 67. The other end shafts 64 b and 65 b of the link members 64 and 65 are movable in the radial direction, and play is provided by the long grooves 68.

  By the rotation of the interlocking plate 66, the link members 64 and 65 move in conjunction between the fixed shaft 61 of the hooks 52 and 53 and the fixed shaft 67 of the interlocking plate 66. As a result, the hooks 52 and 53 can rotate around the fixed shaft 61.

  The drive unit 56 includes a plurality of gears 69 and a restriction motor 70. A restriction motor 70 is provided on the mounting table 71 attached to the base plate 60. A gear 69 is fitted on the motor shaft of the restriction motor 70, and the driving force of the restriction motor 70 is transmitted to the interlocking plate 66 via the plurality of gears 69. When the regulation motor 70 is driven, the interlocking plate 66 rotates around the fixed shaft 67.

  As shown in FIG. 23, the switching unit 54 guides the movement of the other end shafts 64b, 65b of the link members 64, 65. A restriction groove 72 is formed in the mounting table 71, and the other end shafts 64 b and 65 b are fitted into the restriction groove 72. The movement of the hooks 52 and 53 is determined by the movement of the link members 64 and 65 differently by the restriction groove 72. That is, when one hook 52, 53 moves, the other hook 52, 53 is restricted and does not move. The switching unit 54 determines the movement of the hooks 52 and 53 according to the opening direction.

  The regulation groove 72 is formed in a substantially U shape. The restriction groove 72 includes three grooves, that is, an upper lock groove 72a, a neutral groove 72b, and a lower lock groove 72c, and the three grooves are continuously connected. The upper lock groove 72 a is formed along an arc centered on the one end shaft 64 a of the upper link member 64. The lower lock groove 72 c is formed along an arc centered on one end shaft 65 a of the lower link member 65. The neutral groove 72 c is formed along an arc centered on the fixed shaft 67 of the interlocking plate 66.

  As shown in FIGS. 22 (a) and 23 (a), when the other end shafts 64b and 65b are provided in the neutral groove 72b, the hooks 52 and 53 hold the vertical shafts 22 and 23, respectively. , 23 are locked. This state is the initial state. 22B and 23B, when the other end shaft 64b of the upper link member 64 is in the upper lock groove 72a, the upper hook 52 holds the upper shaft 23 and the upper shaft 23 is locked. Is done. The lower hook 53 is detached from the lower shaft 22. 22 (c) and 23 (c), when the other end shaft 65b of the lower link member 65 is in the lower lock groove 72c, the lower hook 53 holds the lower shaft 22, and the lower shaft 22 is locked. Is done. The upper hook 52 is detached from the upper shaft 23.

  When the interlocking plate 66 rotates clockwise in the initial state, the other end shaft 64b of the upper link member 64 moves along the upper lock groove 72a. The other end shaft 64b of the upper link member 64 moves in the circumferential direction around the one end shaft 64a. Since the upper link member 64 does not move in the radial direction, the one end shaft 64a also does not move. Therefore, the upper hook 53 does not rotate. On the other hand, the other end shaft 65b of the lower link member 65 moves along the neutral groove 72b. The one end shaft 65a is pulled and moved. The lower hook 53 rotates clockwise. As a result, the lower shaft 22 is unlocked as shown in FIGS. 22 (b) and 23 (b). When the interlocking plate 66 rotates counterclockwise in the initial state, the upper shaft 23 is unlocked as shown in FIGS. 22 (c) and 23 (c). Note that the control device 41 drives the left and right regulating motors 70 so that the above operation is synchronized in the left and right regulating units 51. The regulating motor 70 uses a stepping motor and is rotated forward and backward depending on the opening direction.

  The moving unit 50 is provided in a pair of left and right inside the cabinet 3 and is disposed on the outer side in the left-right direction than the restricting unit 51. As shown in FIGS. 24 to 26, the front end of the rod 32 protrudes outward from a vertically long hole 21 b (see FIG. 3) formed in the front panel 21. A support shaft 80 for attaching the rod 32 is provided on the support member 31. The front end of the rod 32 is rotatably supported by the support shaft 80. The support shaft 80 is eccentrically positioned closer to the front side than the center in the front-rear direction. The rod 32 has a circular cross section. When the wind hits, it becomes easy for the wind to flow along the surface, so that it is hard to condense even if cold wind is blown. Further, the rod 32 has a hollow structure. As a result, the weight can be reduced while maintaining the strength, and the load on the motor that moves the rod 32 can be reduced.

  The movement mechanism unit 57 moves the front end of the rod 32 forward when opening the wind guide panel 20 and moves backward when closing the wind guide panel 20. The moving mechanism unit 57 is a moving plate 81 that holds the rod 32 and reciprocates. As shown in FIG. 28, the moving plate 81 is formed in a fan shape and is rotatably supported by a fixed shaft 83 fixed to the base plate 82. The base plate 82 is fixed with respect to the cabinet 3.

  The moving unit 50 is also unitized in the same manner as the regulating unit 51. Here, the restricting portion 51 and the moving portion 50 are arranged side by side in the left and right spaces of the cabinet 3. If both are made into one unit, it can be handled as an opening / closing mechanism unit, and attachment work becomes easy. Moreover, since the moving part 50 can be comprised with few components, size reduction and thickness reduction of a unit are realizable. As a result, the opening / closing mechanism can be accommodated in a limited space, and the width of the outlet 5 can be increased. If it becomes the big blower outlet 5, the ventilation range of the width direction will become wide, and it can deliver a wind to every corner of a room.

  The rear end of the rod 32 is rotatably attached to the vicinity of the front end of the moving plate 81 via a rotation shaft 84. An arc groove 85 is formed in the moving plate 81. The arc groove 85 is formed on an arc centered on the fixed shaft 83. A rack is formed in the arc groove 85. The drive unit 58 includes an opening / closing motor 86 and a gear 87 attached to the motor shaft. The gear 87 is inserted into the arc groove 85 and meshes with the rack.

  When the opening / closing motor 86 is driven, the moving plate 81 rotates around the fixed shaft 83 as the gear 87 rotates, and the rod 32 moves in and out of the front panel 21. As shown in FIG. 24, when the wind guide panel 20 is in the closed posture, the moving plate 81 is located on the rear side. Only the front end of the rod 32 protrudes from the front panel 21. Such a state is an initial state.

  When the lower shaft 22 is unlocked and the open / close motor 86 is driven, the movable plate 81 rotates counterclockwise as shown in FIG. The rod 32 is pushed out, and the front end moves forward. The wind guide panel 20 rotates around the upper shaft 23 and opens upward. The opening / closing motor 86 is controlled so that the movable plate 81 rotates by a certain angle, for example, 50 degrees.

  When the upper shaft 23 is unlocked and the open / close motor 86 is driven, the moving plate 81 rotates counterclockwise as shown in FIG. The rod 32 is pushed out, and the front end moves forward. The wind guide panel 20 rotates around the lower shaft 22 and opens downward. At this time, since the wind guide panel 20 is opened so as to be lowered, the front end of the rod 32 moves forward while gradually lowering. Also in this case, the movable plate 81 rotates by a certain angle.

  When the wind guide panel 20 is open, the open / close motor 86 is driven, and when the moving plate 81 rotates clockwise, the wind guide panel 20 is closed. As the moving plate 81 rotates, the rear end of the rod 32 moves backward. The rod 32 is drawn into the cabinet 3. Along with this, the wind guide panel 20 rotates around the upper shaft 23 or the lower shaft 22. The wind guide panel 20 approaches the cabinet 3 and takes a closed posture.

  The control device 41 drives the left and right opening / closing motors 86 so that the above operation is synchronized in the left and right moving units 50. The opening / closing motor 86 uses a stepping motor and is rotated forward and backward according to the opening / closing.

  During the air conditioning operation, when the wind guide panel 20 is open, one of the vertical shafts 22 and 23 is locked in the wind guide panel 20. Here, when the wind guide panel 20 is pulled and an external force is applied, one of the shafts (here, the upper shaft 23) is pushed. When the upper shaft 23 is pushed, the upper hook 52 tries to rotate counterclockwise. The upper link member 64 is pushed in the axial direction. The axial direction is a direction connecting one end and the other end of the upper link member 64. The other end of the upper link member 64 pushes the mounting table 71 through the restriction groove 72. At this time, the direction of the upper lock groove 72a where the other end of the upper link member 64 is located and the axial direction of the upper link member 64 are substantially orthogonal. Due to the mounting table 71 being fixed, the upper link member 64 does not move in the axial direction. The direction in which the force from the upper link member 64 acts is substantially orthogonal to the direction of the upper lock groove 72a. A force in a direction parallel to the direction of the upper lock groove 72 a does not act on the other end of the upper link member 64. Thereby, the upper link material 64 does not move along the upper lock groove 72a, and the rotation of the upper hook 52 is prevented.

  Therefore, even when an external force is applied when the air guide panel 20 is open, the locks can be prevented from being released by making the directions of the link members 64 and 65 and the restriction groove 72 orthogonal to each other. Therefore, it is possible to avoid a situation in which the open air guide panel 20 is supported by the rod 32 and hangs.

  By the way, when the wind guide panel 20 is opened to the maximum, the movement amount of the rod 32 is constant regardless of the opening direction. However, since the position of the front end of the rod 32 with respect to the wind guide panel 20 is eccentric, the opening angle is different between the upper opening and the lower opening as shown in FIGS. The opening angle when opening upward is larger than the opening angle when opening downward. That is, the closer the distance from the center to the fulcrum when opening, the greater the opening angle. The center is the upper shaft 23 or the lower shaft 22, and the fulcrum is the position of the front end of the rod 32. Since the rod 32 is attached near the upper shaft 23, the opening angle of the upper opening is large and the opening angle of the lower opening is small.

  During cooling operation, it opens downward, but if the opening angle is large, the wind guide panel 20 is lowered below the horizontal line. With this, the cold air flows in the horizontal direction, and no air flow toward the ceiling occurs. The reach of cold air is shortened, and cold air hits people directly. Therefore, in the case of downward opening, it is desirable to reduce the opening angle. During heating operation, it opens upward, but if the opening angle is small, the outlet of the hot air becomes narrow. The warm air that has returned to the wind guide panel 20 has no escape, collides with the blown warm air, and the flow is disturbed. As a result, the wind speed blown out toward the floor surface is weakened, and the hot air does not reach the floor surface.

  In this way, efficient air blowing cannot be performed during the cooling / heating operation, and the ability cannot be maximized. However, as described above, by increasing the opening angle of the upper opening and decreasing the opening angle of the lower opening, the cooling air can be blown out toward the ceiling during the cooling operation, and the hot air outlet is opened during the heating operation. It becomes wider and a smooth hot air flow can be formed. Therefore, the maximum capacity of the air conditioner can be exhibited without regret.

  In the air conditioner, the cooling / heating operation is performed according to an instruction when the user operates the remote controller or when a timer setting time is reached. The control device 41 controls the refrigeration cycle 40 and also controls the opening and closing of the wind guide panel 20 and the auxiliary louver 800. At this time, the control device 41 links the moving unit 50 and the regulating unit 51.

  When the air conditioning operation is performed, the control device 41 turns on and off the driving of the restriction motor 70 and the opening / closing motor 86 according to a predetermined timing. Further, the driving of the louver motor 803 of the auxiliary louver 800 is turned on / off. That is, each motor 70, 86, 803 is sequence-controlled.

  The operation timing of the auxiliary louver 800 rotates after the wind guide panel 20 is opened, and closes and rotates the auxiliary louver 800 prior to the closing operation of the wind guide panel. At the time of rapid cooling, the wind guide panel 20 once takes an upward opening posture around the upper shaft and then switches to a lower opening posture around the lower shaft through a closing posture. At this time, the auxiliary louver 800 is The sequence control is performed so that the air guide panel 20 is opened after the air guide panel 20 is opened, and is closed and rotated before the air guide panel 20 is closed.

  Further, the control device 41 performs an initial operation prior to the start of operation. That is, the control device 41 determines the position of the wind guide panel 20 when the operation is stopped, and operates the moving unit 50 and the regulating unit 51 so as to be in the initial state as the initial operation when not in the initial state. At the start of operation, when in the initial state, the operation is started without performing the initial operation. The initial state is when the wind guide panel 20 is in the closed position, and the opening angle of the wind guide panel 20 and the states of the members of the moving unit 50 and the regulating unit 51 are related.

  As shown in FIG. 24, a position detection sensor 90 for detecting the position of the wind guide panel 20 is provided in the moving unit 50. The position detection sensor 90 is provided on the left and right moving units 50. The position detection sensor 90 is a limit switch. The position detection sensor 90 is attached to the base plate 82 of the moving unit 90 in the cabinet 3. The position detection sensor 90 is disposed so as to be close to the moving plate 81 in the initial state. When in the initial state, the rod 32 attached to the moving plate 81 contacts the position detection sensor 90. Therefore, the position detection sensor 90 detects that the wind guide panel 20 is in the initial state, that is, in the closed posture.

  Note that the position detection sensor 90 may directly detect the position of the wind guide panel 20, and is not limited to a contact sensor such as a limit switch, and may use a non-contact sensor such as an optical sensor or a camera.

  The control device 41 determines whether or not it is in the initial state based on the detection signal of the position detection sensor 90. Normally, when the operation is stopped, the wind guide panel 20 is in a closed posture, and the moving unit 50 and the regulating unit 51 are in an initial state. However, for some reason, when not in the initial state, the control device 41 determines that it is not in the initial state based on the detection signal from the position detection sensor 90. Therefore, the control device 41 performs an initial operation and forcibly sets the initial state.

  Conventionally, the time from when the wind guide panel 20 is in the most open state to the closed state (initial state) is stored as an initialization time, and during the initialization time at the start of cooling or heating operation, the wind guide panel is stored. After the initial operation of closing 20 is always performed, normal operations such as cooling and heating are performed. However, in such a conventional initial operation, the initial operation is always performed during the initialization time even when the operation is in the initial state such as the cooling operation or the heating operation, so that the normal operation of the cooling operation or the heating operation is performed. It took time to move.

  By providing the position detection sensor 90 as in the present embodiment, it is possible to detect whether or not the wind guide panel 20 is in the initial state at the start of operation, so that the wind guide panel 20 is in the initial state at the start of operation. In this case, the cooling operation and the heating operation can be performed without performing the initial operation.

  Further, when the wind guide panel 20 is not in the initial state at the start of operation, the initial operation is performed, and the initial operation is terminated when the position detection sensor 90 detects that it is in the initial state, and the operation proceeds to the cooling operation or the heating operation. be able to. The initial operation is performed even when the wind guide panel 20 is not in the most open state but in a slightly open state or a state in which the wind guide panel 20 is opened to the middle, but when the position detection sensor 90 detects that it is in the initial state, the initial operation is performed. Since the operation is terminated, it is possible to shift to the cooling operation or the heating operation without performing the initial operation during the initialization time.

  As described above, the time required for the initial operation can be reduced by using the detection result from the position detection sensor 90, and the normal operation can be promptly started. When the position detection sensor 90 does not detect that the wind guide panel 20 is in the initial state, the opening operation of the wind guide panel 90 is not performed, but only the closing operation is performed.

  If the wind guide panel 20 does not go into the initial state even after the initial operation has been performed for a predetermined time, the wind guide panel 20 is temporarily opened for the time required to make the wind guide panel 20 fully open, that is, from the closed state to the fully open state. To fully open. Then, the auxiliary louver 800 may be closed, and then the wind guide panel 20 may be closed. Even if this operation is performed, if the position detection sensor 90 cannot detect that the wind guide panel 20 is in the initial state, an error is displayed as an operation failure.

  In addition, when the outlet of the air conditioner is connected to the commercial power supply for the first time, or when the energization of the air conditioner is temporarily interrupted due to a power failure or the like, it is necessary to close the auxiliary louver 800. The wind guide panel 20 is opened until at least the auxiliary louver 800 can be rotated (for example, the wind guide panel 20 is opened until the auxiliary louver 800 is fully opened). To do.

  In the initial state, in the moving unit 50, as shown in FIG. 24, the moving plate 81 is at the rear position. In the restricting portion 51, as shown in FIGS. 21 and 23 (a), the other end shafts 64b and 65b of the upper and lower link members 64 and 65 are positioned in the neutral groove 72b.

  When the heating operation is started, the control device 41 first drives the regulation motor 70 of the regulation unit 51. By this driving, the interlocking plate 66 rotates clockwise. The upper link member 64 rotates around one end. The lower link member 65 is pulled up by the other end shaft 54b of the lower link member 65 moving along the neutral groove 72b. The lower hook 53 rotates clockwise, and the lower shaft 22 is unlocked.

  The control device 41 drives the opening / closing motor 86 of the moving unit 50 with a slight delay from the activation timing of the regulation motor 70. The start timing of the opening / closing motor 86 is after the lower hook 53 is separated from the lower shaft 22. That is, the control device 41 stops the restriction motor 70 when the predetermined first timing is reached. As shown in FIG. 23B, the first timing is a timing determined according to the time until the other end shaft 64b of the upper hook member 64 reaches the end of the upper lock groove 72a. After stopping the regulation motor 70, the control device 41 drives the opening / closing motor 86.

  By driving the opening / closing motor 86, the moving plate 81 rotates counterclockwise. The rod 32 is pushed forward, and the wind guide panel 20 moves in a direction away from the cabinet 3. The wind guide panel 20 opens around the upper shaft 23. When the set opening angle is reached, the control device 41 stops the opening / closing motor 86. The opening angle is calculated from the number of steps of the opening / closing motor 86.

  The control device 41 drives the open / close motor 86 for a predetermined time, and stops the open / close motor 86 at the second timing. At this time, the maximum opening angle as shown in FIG. 25 is reached. The wind guide panel 20 is in an upwardly open posture, and warm air is blown out toward the floor surface.

  Thereafter, the control device 41 controls the operation of the louver motor 803, opens the auxiliary louver 800 to a predetermined angle, and blows warm air toward the floor.

  Also in the cooling operation, the control device 41 controls the restriction motor 70 and the opening / closing motor 86 at the same timing. However, the regulation motor 70 is rotated in the opposite direction to that during the heating operation. The opening / closing motor 86 is rotated in the same direction.

  The opening / closing motor 86 stops at the second timing when it is driven for a certain time. At this time, the maximum opening angle as shown in FIG. 26 is reached. The wind guide panel 20 is in a downward opening posture, and cold air is blown out toward the ceiling. Thereafter, the control device 41 controls the operation of the louver motor 803, causes the auxiliary louver 800 to be oriented in parallel with the flow of the wind, and blows cool air toward the ceiling.

  When the air conditioning operation is finished, the control device 41 first operates the louver motor 803 to close the auxiliary louver 800. Next, the opening / closing motor 86 is driven. The rod 32 is pulled back and the wind guide panel 20 approaches the cabinet 3. The control device 41 stops the opening / closing motor 86 when the predetermined third timing is reached. At this time, as shown in FIG. 24, the wind guide panel 20 is in a closed posture, and the movable plate 81 is in the rear position. That is, the third timing is a timing determined according to the time when the movable plate 81 returns to the initial state. The position detection sensor 90 detects that the movable plate 81 has returned to the initial state. The third timing may be in accordance with this detection timing.

  Thereafter, the control device 41 drives the restriction motor 70. For example, when the heating operation is performed, the state changes from the state shown in FIG. 23B to the state shown in FIG. The lower hook 53 rotates and the lower shaft 22 is locked. The control device 41 stops the regulating motor 70 when the predetermined fourth timing is reached. The fourth timing is determined according to the time until the other end shaft 65b of the lower link member 65 reaches the connection position between the neutral groove 72b and the lower lock groove 72c from the connection position between the upper lock groove 72a and the neutral groove 72b. It is the timing.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. A locking portion may be provided on the support material, and the wind guide panel is gripped and locked. As a holding part, you may provide a rotating shaft in a wind guide panel and a bearing in a support material.

  Further, the locking portion may be provided in the middle of the wind guide panel, and the holding portions may be provided on the front side and the rear side to provide three-point support. In this case, the rotation shaft of the holding portion is made slidable in the left-right direction, and the rotation shaft is pushed in, so that it can be detached from the bearing and easily detached.

  Different from the air conditioner of the present embodiment, an air conditioner having a structure in which a support member that supports an air guide panel that opens and closes an air outlet is rotatably attached (or rotatable) in the vicinity of the distal end of the arm portion. Also, the above panel structure can be applied. In this case, it is not necessary to provide an upper shaft or a lower shaft as in this embodiment. That is, the rod is replaced with an arm portion, and a driving component such as a gear is accommodated in the arm portion.
