  In general, an air conditioner is installed at a position at which indoor air can be harmonized most efficiently when air is blown forward from the air outlet. At this time, the wind direction plate that controls the wind direction in the left-right direction is held in a neutral posture parallel to the blowing direction of the air flowing through the outlet.

  However, there may be a case where it is desired to temporarily concentrate the air in one of the left and right directions of the air outlet and blow out the air. In such a case, the air is deflected in the left and right direction and the air is blown from the air outlet. Adjust the horizontal direction of the. However, when it is no longer necessary to blow air in a specific direction, it is necessary to return the direction of the wind direction plate to the original neutral posture in order to blow air forward from the blowout port.

  In order to change the direction of the wind direction plate, it is preferable to provide a driving device for automatic operation. However, as described above, in the case of an air conditioner having a wind direction plate on the panel, the wind direction on the panel is set. It is necessary to install a driving device for the plate, and the structure becomes complicated, and there arises a problem that the driving device becomes an obstacle to the air flowing along the panel.

  Therefore, in the present invention, in view of the above, in an air conditioner in which a wind direction plate is installed on a panel, a driving device is not installed on the panel, and the wind direction plate is set to a neutral posture with a simple configuration without manual operation. It aims at providing the air conditioner which can be returned.

  In order to achieve the above object, an air conditioner according to an aspect of the present invention includes a cabinet having an air outlet, and an up-down direction of air that is disposed in front of the air outlet and opens and closes the air outlet and blows out from the air outlet. And a wind direction changing device provided on the panel. The wind direction changing device has a plurality of interlocking wind direction plates, and is parallel to the air blowing direction of the air flowing through the air outlet. The wind direction plate taking a neutral position is configured to change the left and right direction of the air blown from the outlet by deflecting the wind direction plate in the left and right direction with respect to the blowing direction, and the plurality of wind direction plates are arranged in the left and right direction. When the panel is closed, a guide portion is provided for guiding at least one of the wind direction plates located at both left and right ends of the plurality of wind direction plates to a neutral posture.

  According to the air conditioner according to the aspect of the present invention, in the air conditioner in which the wind direction changing device is provided on the panel arranged in front of the air outlet, the left and right ends of the plurality of wind direction plates of the wind direction changing device. Since the guide unit that guides at least one of the wind direction plates located in the neutral position is provided, the drive unit is not installed on the panel, and the wind direction plate can be easily closed by closing the panel without manually operating the wind direction plate.

[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In this embodiment, a separate type air conditioner including an indoor unit and an outdoor unit (not shown) will be described. FIG. 1 is a perspective view showing a state in which the panel of the indoor unit of the first embodiment is opened upward, and FIG. 2 is a side view thereof. 3 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 4 is a cross-sectional view showing a state where the panel of the indoor unit is opened downward in FIG.

  As shown in FIGS. 1 to 4, the indoor unit includes a heat exchanger 1 and a blower 2, and these are housed in a cabinet 3. A suction port 4 is formed on the top surface of the cabinet 3, and an air outlet 5 is formed on the lower front surface of the cabinet 3. Inside the cabinet 3, an air passage 6 is formed from the suction port 4 to the air outlet 5, and the heat exchanger 1 and the blower 2 are arranged in this air passage 6 in this order from the upstream side of the air flow. The

  In the present embodiment, a cross flow fan is used as the blower 2, and air flows in the direction from the blower 2 to the blower outlet 5 (the blowing direction W) through the rotation of the crossflow fan. The blower outlet 5 has a shape that is long in the left-right direction X, and a panel 8 that is supported by the movable arm 7 and that covers the blower outlet 5 is attached to the front surface of the blower outlet 5 so as to be openable and closable. The panel 8 constitutes a part of the cabinet 3 in a closed state (a state where the air outlet 5 is closed).

  An upper shaft 9 and a lower shaft 11 that are parallel to the left-right direction X are provided at the upper end portion and the lower end portion of the panel 8 in a state in which the air outlet 5 is closed. And the panel 8 can be rotated in a different direction by operating the movable arm 7 around the upper or lower axis from the state where the outlet 5 is closed, that is, the panel 8 can be opened both vertically. In the air conditioner of the present embodiment, the panel is closed when the air conditioning operation is stopped, and the panel is opened upward or downward when the air conditioning operation is started.

  Specifically, as shown in FIGS. 1 to 3, the panel 8 is rotated by rotating the upper end of the panel 8 around the lower shaft 11 with the lower end of the panel 8 being close to the lower end of the outlet 5. 8 opens up. Further, as shown in FIG. 4, the panel 8 is opened downward by rotating the lower end side of the panel 8 around the upper shaft 9 in a state where the upper end of the panel 8 is brought close to the upper end of the outlet 5. . When the operation mode is switched or when the panel is opened or closed, the panel is opened again through a state where the panel is once closed.

  As described above, by allowing the panel 8 to be opened up and down, the conditioned air can be blown out in a direction (vertical direction) more suitable for the operation mode. In addition, the structure which enables the panel 8 supported by the movable arm 7 to be opened both up and down is already known. For example, the structure described in JP2009-63258A, JP2009-257606A, JP2013-47590A, or the like. Can be adopted.

  A wind direction changing device 12 is provided on the inner surface of the panel 8. The wind direction changing device 12 includes a plurality of wind direction plates 13 as shown in FIG. The wind direction plate 13 includes a blade portion 14 and a shaft portion 15 that rotatably supports the blade portion 14, and a plurality of the wind direction plates 13 are erected on the panel 8 at intervals in the left-right direction X. The wind direction plate 13 may be directly attached to the panel 8, or the wind direction plate 13 is first mounted on the substrate to form a unit, and the unitized substrate can be fitted with the substrate provided on the panel 8. It is also possible to incorporate it into a simple recess.

  The wind direction plates 13 are coupled to each other by an interlocking rod 16 so that when the direction of any wind direction plate 13 is manually changed, the other wind direction plates 13 are also linked and changed to the same direction. The Specifically, as shown in FIG. 1, when the wind direction plate 13 takes a neutral posture parallel to the air blowing direction W of the air flowing through the air outlet, the air blows straight out from the air outlet without being biased in the left-right direction. Is done. By deflecting the wind direction plate 13 in the left-right direction with respect to the blowing direction W, the air is blown out by changing the direction in the left-right direction of the outlet.

  6 is a cross-sectional view taken along the line BB of FIG. 1, FIG. 7 is a partially enlarged view of the CC cross-section of FIG. 2, and FIG. 8 is a schematic plan view of the air conditioner with the panel opened upward. FIG. As illustrated, in the present embodiment, a guide portion 21 is formed on the panel 8 to guide the wind direction plate 13 located at the left end among the plurality of wind direction plates 13 arranged in the left-right direction to a neutral posture. The wind direction plates 13 other than the wind direction plate 13 located at the left end are accommodated in the air outlet 5 with the panel 8 closed.

  The guide portion 21 is provided on the left side of the air outlet 5 separately from the air outlet 5 in the cabinet 3. The panel 8 is sized to cover the air outlet 5 and the guide portion 21 in a closed state. Accordingly, the panel 8 also functions as a cover for the guide portion 21 and prevents entry of dust or the like into the guide portion 21.

  A recess 20 is provided on the left side of the air outlet 5, and a guide portion 21 is formed in the recess 20. The guide portion 21 includes a right guide surface portion 22 and a left guide surface portion 23 that restrict the direction of the wind direction plate 13 from the left and right so that the wind direction plate 13 takes a neutral posture with the panel 8 closed. And it is provided so that the distance of the right guide surface part 22 and the left guide surface part 23 which opposes may spread gradually as it goes to the front side of the cabinet 3. As shown in FIG. In other words, the distance between the right guide surface portion 22 and the left guide surface portion 23 becomes narrower toward the back. In addition, the space | interval of the right guide surface part 22 and the left guide surface part 23 is made into some extent a little rather than the thickness of the wind direction board 13 in the back | inner side.

The manner in which the wind direction plate 13 is guided to the neutral position will be described by taking as an example the case where the wind direction plate 13 of the wind direction changing device 12 is deflected in the left-right direction and the panel 8 is closed from the state where the panel 8 is opened upward. To do. First, as shown in FIG. 9, when the upper end portion of the panel 8 is turned toward the blowout port 5 around the lower shaft 11 of the panel 8, the top portion of the wind direction plate 13 positioned at the left end becomes the guide portion 21. Contact.
After that, the wind direction plate 13 remains in contact with the guide portion 21 and rotates counterclockwise on the drawing as shown in FIG. 10 along the right guide surface portion 22 and the left guide surface portion 23 as the panel 8 rotates. Rotate. Finally, as shown in FIG. 11, the wind direction plate 13 takes a neutral posture with the panel 8 closed. In addition, the shape of the blade portion 14 of the wind direction plate 13 guided by the guide portion 21 is not particularly limited, but it is preferably a substantially trapezoidal shape in which the upper side is shorter than the bottom side.

  As a result, the left and right widths of the entrance of the guide portion 21 necessary for guiding the wind direction plate 13 can be suppressed, and guidance to the neutral posture can be performed smoothly. In the present embodiment, the shape of the blade portion 14 is a substantially isosceles trapezoid, the lower side is gently curved downward, and the corner of the upper side is rounded. A shaft portion 15 is formed at the center of the blade portion 14 and is symmetric about the shaft portion 15. Moreover, as a shape of the guide part 21, it is preferable that a cross-sectional shape is a trumpet shape. Thereby, it becomes possible to guide the wind direction board 13 more smoothly.

  The wind direction plate 13 guided by the guide part 21 and the other wind direction plate 13 may be different in shape, but the other wind direction plate 13 is also substantially trapezoidal like the wind direction plate 13 guided by the guide part 21. By doing so, it is possible to avoid the wind direction plate 13 coming into contact with the air outlet 5 when the panel 8 opens both vertically.

  The air conditioner having the above configuration can return the direction of the wind direction plate 13 to the neutral posture by closing the panel 8, and a highly convenient air conditioner can be obtained. In the present embodiment, the panel 8 is closed when the air-conditioning operation is stopped, and the panel is opened again after the panel is closed once when the operation mode is switched or when the panel is opened or closed. It becomes possible to return the wind direction plate 13 to the neutral posture for each knot. Moreover, since the guide part 21 is provided in the left side of the blower outlet 5, it suppresses obstructing the air which blows off from the blower outlet 5, and suppresses adhesion to the guide part 21 of the dust etc. which are contained in conditioned air. Can do.

  In the air conditioner of the type in which the panel opens up and down with respect to the air blowing direction from the air outlet 5, the following inconvenience occurs. For example, the guide portion 21 is provided when the panel 8 is changed to the downward opening instead of the air blowing toward the left of the outlet 5 by deflecting the wind direction plate 13 to the left with the panel 8 opened upward. If not, the wind direction plate 13 is deflected rightward with the panel 8 opened downward, and air is blown out to the right of the outlet. That is, air blows out in the opposite direction from the time of opening upward, and the convenience of the air conditioner is significantly reduced.

  Even in such a case, if the guide portion 21 is provided, the wind direction plate 13 is opened again when the panel 8 is opened again through the state where the panel 8 is once closed when the operation mode is switched or when the panel 8 is opened or closed. Can take a neutral posture and can blow out air straight from the air outlet without biasing the air in the left-right direction, thereby avoiding a significant decrease in the convenience of the air conditioner.

  In the present embodiment, the guide portion 21 is formed on the left side of the air outlet 5, but of course, it may be formed on the right side of the air outlet 5. Furthermore, it is also possible to form the guide portions 21 at two locations on the right side and the left side of the air outlet 5 so as to guide the two wind direction plates located at the right end and the left end of the plurality of wind direction plates 13.

  In this case, the wind direction plate 13 can be made to be in a neutral posture more smoothly and reliably, and the wind direction plate 13 is located further outward than the left and right side walls of the air outlet 5, so that air blown out from the air outlet 5 is more than necessary. It is possible to suppress the spread in the right and left direction by the wind direction plates 13 located at both the left and right ends, and to send air more accurately in a desired direction.

[Second Embodiment]
FIG. 12 is a schematic plan view showing the air conditioner of the second embodiment. In the present embodiment, as the wind direction changing device, a right wind direction changing device located on the right side of the air outlet and a left wind direction changing device located on the left side of the air outlet are provided, and as the guide portion, at the right end in the right wind direction changing device. It is characterized in that a right guide part for guiding the wind direction plate located and a guide part for guiding the wind direction plate located at the left end in the left wind direction changing device are provided. The basic configuration of the air conditioner is the same as that of the first embodiment.

  As shown in FIG. 12, in this embodiment, as a wind direction change apparatus, the right wind direction change apparatus 18 provided in the right side rather than the horizontal direction center of the blower outlet 5 seeing from the cabinet 3 side, and the horizontal direction center of the blower outlet 5 And a left wind direction changing device 19 provided on the left side. The right wind direction changing device 18 and the left wind direction changing device 19 are configured in the same manner as the wind direction changing device 12 of the first embodiment, and include a wind direction plate 13 and an interlocking rod 16.

  Furthermore, as a guide part, the right guide part 25 which guides the wind direction board 13 located in the right end in the right wind direction change apparatus 18 and the left guide part 26 which guides the wind direction board 13 located in the left end in the left wind direction change apparatus 19 are provided. Prepare. The right guide part 25 and the left guide part 26 are configured similarly to the guide part 21 of the first embodiment, and include a right guide surface part 22 and a left guide surface part 23.

  The right guide portion 25 is provided on the right side of the air outlet 5 in the cabinet 3, and the left guide portion 26 is provided on the left side of the air outlet 5. That is, the left and right guide portions 25 and 26 are provided at two locations on the right side and the left side of the air outlet 5. The wind direction plates 13 other than the wind direction plate 13 positioned at the right end in the right wind direction changing device 18 and the wind direction plate 13 positioned at the left end in the left wind direction changing device 19 are accommodated in the outlet 5 with the panel 8 closed. Is done.

  In the air conditioner having the above-described configuration, the right wind direction changing device 18 and the left wind direction changing device 19 can blow out air in any direction in the left-right direction X, and the direction of the wind direction plate 13 is closed by closing the panel 8. Can be returned to the neutral position. Moreover, since the wind direction plate 13 is located further outside the left and right side walls 31 and 32 of the air outlet 5, the air direction plates 13 located at the left and right ends of the air blown from the air outlet 5 spread more than necessary in the left and right direction X. It is possible to suppress air flow and to send air more accurately in a desired direction.

[Third Embodiment]
The present embodiment is characterized in that a pair of guide arms provided so as to be rotatable about the same axis is used as the guide portion, and the air conditioner guide shown in the first embodiment or the second embodiment is used. It can be suitably used in place of the part.

  As a specific example, the case where the guide part 21 of the air conditioner in 1st Embodiment is changed is demonstrated. The basic configuration of the air conditioner is the same as that of the first embodiment. As shown in FIGS. 13 to 15, the guide portion 41 in the present embodiment is installed in a recess 20 formed on the left side of the air outlet 5. The guide part 41 includes a right guide arm 42, a left guide arm 43, and a holding part 44 that holds the left and right guide arms 42 and 43 coaxially and independently so as to be rotatable.

  The holding unit 44 includes a rotating shaft 45 and a rotating cylinder 46 that is externally mounted on the rotating shaft 45. A stepping motor (not shown) is installed on the base side of the holding portion 44 so that the rotating shaft 45 and the rotating cylinder 46 can be rotated by the stepping motor independently. The indoor unit is provided with a control device that controls the rotation of the rotating shaft 45 and the rotating cylinder 46. The control device is composed of a microcomputer. A bearing portion 47 of the rotating shaft 45 is provided on the distal end side of the holding portion 44. The right guide arm 42 is fixed to the rotating shaft 45, and the left guide arm 43 is fixed to the rotating cylinder 46.

  As shown in FIG. 16, when the air conditioner is viewed from the front, the left and right guide arms 42, 43 are always between the guide arms 42, 43 except when the direction of the wind direction plate 13 is changed in the recess 20. Is held in a V shape with the angle of being widened (in a state where the guide arm is opened). As shown in FIG. 17, when the panel 8 is closed, the angle between the two guide arms 42 and 43 is such that the wind direction plate 13 is deflected in the left-right direction and does not come into contact with the two guide arms 42 and 43. It is assumed that the angle is accommodated.

  When returning the wind direction plate 13 to the neutral posture, the angle between the guide arms 42 and 43 is narrowed by rotating the guide arms 42 and 43 in the 12 o'clock direction on the drawing of FIG. 17 (the guide arm is closed). And the wind direction plate 13 is guided from the left and right to the neutral posture. The guide arms 42 and 43 after guiding the wind direction plate 13 to the neutral posture return to the original open state as shown in FIG.

  More specifically, with respect to the rotation of each guide arm 42, 43, the right guide arm 42 rotates clockwise and the left guide arm 43 rotates counterclockwise. The rotating guide arms 42 and 43 are in contact with the wind direction plate 13 deflected in the left-right direction X at a position eccentric from the shaft portion 15. As a result, the wind direction plate 13 can be rotated around the shaft portion 15 to be in a neutral posture (see FIGS. 14 and 15).

  In the present embodiment, it is possible to prevent the wind direction plate 13 from being guided to the neutral posture only by holding the guide arm in the open state. That is, the user can select whether or not to return the direction of the wind direction plate 13 to the neutral posture.

  Further, in the present embodiment, it is possible not only to return the wind direction plate 13 to the neutral posture, but also to change the direction of the wind direction plate 13 in an arbitrary left and right direction. As a specific example, a case where the neutral wind direction plate 13 is deflected in the left-right direction X will be described.

  In the state where the panel 8 is closed, one of the left and right guide arms 42 and 43 in the open state is rotated to contact the wind direction plate 13 with respect to the wind direction plate 13 which takes a neutral posture. As shown, the rotation of the guide arm may be stopped when the wind direction plate 13 is deflected in a desired direction. Actually, the rotation of the guide arms 42 and 43 can be automatically controlled by remote control using a remote controller.

  Thus, in this embodiment, it is possible to change the wind direction plate 13 of the wind direction changing device 12 in an arbitrary direction by remote operation without installing the driving device of the wind direction changing device 12 on the panel 8. It becomes.

  Furthermore, the air conditioner of this embodiment can also hold the inclination of the wind direction plate deflected in the left-right direction so that the inclination is the same when the panel 8 is opened upward and downward when the panel 8 is opened and closed. . Specifically, the case where the opening of the panel 8 is switched from the upwardly opened state to the downwardly opened state will be described.

  First, in response to a signal from the remote controller, the control device rotates one of the left and right guide arms 42 and 43 to deflect the wind direction plate to a desired angle, and the angle of the rotated guide arm is determined by the left and right guide arms. The rotation of the arms 42 and 43 is stored (angle setting). Thereafter, the panel 8 opens upward and blows air from the outlet 5 in either the left or right direction.

  The panel 8 is temporarily closed by the operation mode switching operation or the up / down wind direction changing operation. At this time, the control device rotates a guide arm that is different from the guide arm that is rotated when the left and right wind directions are set, among the left and right guide arms 42 and 43. The control device rotates the other guide arm based on the angle of one guide arm memorized at the time of angle setting, and the guide arm is located when the direction of the wind direction plate is symmetrical to the direction of the wind direction plate at the time of angle setting. Is stopped, the initial guide arm is returned to the open state, and then the panel is opened downward. Thereby, when switching the panel 8 up and down, the inclination of the wind direction plate deflected in the left-right direction can be held so as to be the same when the panel is opened upward and when it is opened downward.

  In this embodiment, after changing the wind direction of the wind direction plate 13 with the panel 8 closed, the panel 8 is opened and the air conditioning operation is started. Further, in the state in which the panel 8 is opened, the direction of the wind direction plate 13 can be manually changed in the same manner as in the first and second embodiments.

  As described above, in the present embodiment, the example in which the guide portion 41 is provided beside the air outlet 5 has been described. However, as another example, as illustrated in FIG. 20, the guide portion 41 can be installed in the air outlet 5. is there. In this example, a motor for driving the left and right guide arms 42 and 43 may be disposed on the back side of the rear guider 33 that constitutes the lower wall of the blowout port 5, and the holding unit 44 may be installed so as to penetrate the rear guider 33. .

  Since the guide part 41 of this embodiment is compact, it does not become a hindrance of the air flow of the blower outlet 5, and a free layout is attained. Therefore, among the plurality of wind direction plates 13 in the wind direction changing device 12, it is possible to install not only the wind direction plate 13 positioned at the end but also the direction of an arbitrary wind direction plate 13.

[Fourth Embodiment]
FIG. 21 is a schematic plan view showing the air conditioner of the fourth embodiment. This embodiment is characterized in that the left and right side walls constituting the air outlet are used as guide portions. The basic configuration of the air conditioner is the same as that of the first embodiment.

  As shown in FIG. 21, in this embodiment, the right side wall 31 portion constituting the air outlet 5 is the right guide surface portion 22, and the left side wall 32 portion of the air outlet is the left guide surface portion 23. In other words, since the plurality of wind direction plates 13 are connected so as to be interlocked by the interlocking rod 16, the entire plurality of wind direction plates 13 can be regarded as one wind direction plate.

  Therefore, in this embodiment, the entire wind direction plate 13 is restricted from the left and right by the right guide surface portion 22 and the left guide surface portion 23. The space between the right guide surface portion 22 and the left guide surface portion 23 is somewhat more marginal than the inter-axis distance from the wind direction plate 13 located at the right end to the wind direction plate 13 located at the left end on the farthest side of the guide portion. . The right guide surface portion 22 and the left guide surface portion 23 are provided so that the distance between the two gradually increases from the back side of the cabinet 3 toward the front side.

  When the panel 8 is closed while the wind direction plate 13 is deflected in the left-right direction, the wind direction plate 13 located at the right end contacts the right guide surface portion 22, and the wind direction plate 13 located at the left end contacts the left guide surface portion 23. . Thereafter, the wind direction plate 13 is guided to the neutral posture along the right guide surface portion 22 and the left guide surface portion 23 as the panel 8 rotates while contacting the guide portion. In the said structure, it becomes possible to return the wind direction board 13 to a neutral attitude | position by the simple structure which changes the shape of the left-right side walls 31 and 32 part which comprises the blower outlet 5. FIG.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. For example, in the first to fourth embodiments, the air conditioner of the type in which the panel 8 opens both up and down has been described, but the air conditioner of the type that only opens up may be used.

  In the first embodiment and the second embodiment, the example in which the guide portion is fixed to the cabinet 3 has been described. However, the present invention is not limited thereto, and the guide portion 21 is unitized as a separate body from the cabinet 3 and unitized. It is also possible to provide the guide portion 21 so as to be switchable between two positions, a guideable position where the wind direction plate 13 can be guided to the neutral position and a guide impossible position where the wind direction plate 13 cannot be guided to the neutral position.

  Specifically, an example in which the guide portion 21 of the air conditioner in the first embodiment is modified is shown in FIG. As illustrated, in the air conditioner of this modification, the guide portion 21 unitized in the front-rear direction of the cabinet 3 is movable. That is, the guide portion 21 can be switched and moved between a guideable position where the wind direction plate 13 at the front of the cabinet 3 can be guided to a neutral position and a guide impossible position where the wind direction plate 13 at the back of the cabinet 3 cannot be guided to a neutral position. It is said.

  For example, when it is desired to fix the air blowing direction in the left-right direction X, the guide portion 21 may be retracted to a non-guideable position where the wind direction plate 13 does not contact. When the wind direction plate 13 is desired to be in a neutral posture, the guide portion 21 may be advanced to a guideable position. Thereby, when the panel 8 is closed, it is possible to select whether the orientation of the wind direction plate 13 deflected in the left-right direction X is maintained or the neutral posture is set.

  Moreover, in 1st Embodiment and 2nd Embodiment, although the guide part (or right-and-left guide part) is provided in the right side and / or left side of the blower outlet 5, the guide part or right-and-left guide part is provided in the blower outlet 5. It is also possible to provide. Specifically, FIG. 23 shows a modification in which the guide portion 21 of the air conditioner in the first embodiment is provided in the air outlet 5.

  As shown in the drawing, the air conditioner of the present modification is provided with a right guide surface portion 22 and a left guide surface portion 23 as guide portions 21 in the outlet 5. In addition, the left guide surface part 23 can be comprised by the left side wall 32 part of the blower outlet 5. FIG. The right guide surface portion 22 and the left guide surface portion 23 are formed apart from each other, and air can flow between them.

  Moreover, in 1st Embodiment-4th Embodiment, although it is set as the structure which changes the wind direction in left and right arbitrary directions by pinching the blade | wing part 14 of the wind direction board 13 directly with the panel 8 open, the wind direction It is also possible to change the direction of the wind direction plate from the surface opposite to the surface where the wind direction plate is erected without touching the blade portion 14 of the plate 13, that is, from the outer surface of the panel.

  Specifically, an example in which the air conditioner in the first embodiment is modified is shown in FIG. As illustrated, in the present modification, an operation lever 51 is projected from the lower side of the wind direction plate 13 toward the panel 8. The panel 8 is formed with a long hole 52 through which the operation lever 51 passes and exposed to the surface side of the panel 8. The long hole 52 is formed in an arc shape with the shaft portion 15 as the center, and the operation lever 51 can be slid left and right. Thereby, even when a hand cannot reach directly to the wind direction board 13, the direction of the wind direction board 13 can be changed by sliding the operation lever 51. FIG.

  The operation lever 51 can also be provided at the upper end and lower end of the panel 8 as shown in FIG. In this case, the operation lever 51 is installed to be slidable in the left-right direction at the upper end portion and the lower end portion of the panel 8. A long hole (not shown) is provided at the end of the operation lever 51 opposite to the operation portion. On the lower side of the wind direction plate 13, a convex portion 53 is provided at a position eccentric from the shaft portion 15, and the convex portion 53 is loosely fitted in the long hole of the operation lever 51.

  In the above configuration, when one operation lever 51 is slid, the direction of the wind direction plate 13 is changed, and the other operation lever 51 is also slid in conjunction with the rotation of the wind direction plate 13. Thus, in this example, the direction of the wind direction plate 13 is easily changed because the operation lever 51 is located at the tip of the opened panel 8 regardless of whether the panel 8 is opened in the upward or downward direction. can do. In addition, although the example which installed the operation lever 51 in both the upper end part and lower end part of the panel 8 was shown in FIG. 25, installing the operation lever 51 only in either the upper end part or the lower end part of the panel 8 is shown. Is also possible.

  An example of changing the direction of the wind direction plate 13 without touching the blade portion 14 of the wind direction plate 13 other than using the operation lever 51 is shown in FIGS. In this case, the shaft 15 may penetrate the panel 8 and be exposed to the panel surface side. According to this configuration, the direction of the wind direction plate 13 can be changed by pinching the shaft portion 15 with a fingertip, and the influence on the appearance on the panel surface side can be minimized. In this example, an operation portion 54 (a knob, a handle, a dial, a lever, or the like) that enlarges the diameter of the shaft is provided in a portion exposed to the panel surface side of the shaft portion 15. Thus, by providing the operation unit 54, the operability is improved and the appearance can be accented, which is preferable in terms of design.

  The constituent elements disclosed in the first to fourth embodiments and the above-described modifications can be combined with each other, and new technical features can be formed by combining them.

  As is clear from the description of the above embodiment, an air conditioner as one aspect of the present invention is provided with a cabinet having a blower outlet and air that is disposed in front of the blower outlet, opens and closes the blower outlet, and blows out from the blower outlet. Panel and a wind direction changing device provided on the panel, the wind direction changing device has a plurality of wind direction plates interlocking, in the direction of blowing the air flowing through the outlet The wind direction plate that takes a neutral posture parallel to the air blowing direction is deflected in the left-right direction with respect to the air blowing direction so as to change the direction of the air blown from the air outlet in the left-right direction. When the panel is closed, a guide portion is provided for guiding at least one of the wind direction plates located at the left and right ends of the plurality of wind direction plates to a neutral posture when the panel is closed. To. Thereby, it becomes possible to return the direction of a wind direction board to a neutral attitude | position by closing a panel, and a highly convenient air conditioner can be obtained.

  Further, as the wind direction changing device, a right wind direction changing device located on the right side of the air outlet and a left wind direction changing device located on the left side of the air outlet are provided, and the guide portion is located at the right end in the right wind direction changing device. A right guide part for guiding the wind direction plate to be provided and a left guide part for guiding the wind direction plate located at the left end in the left wind direction changing device may be provided. According to the above configuration, it is possible to make all the wind direction plates have a neutral posture when the panel is closed while allowing air to be blown out in any direction in the left-right direction between the right and left sides of the outlet. Become.

  A guide part can be set as the structure provided in the right side and / or the left side of the said blower outlet. Thereby, while preventing that the air which blows off from a blower outlet becomes obstructed, adhesion of dust etc. to a guide part can be controlled.

  In addition, the guide portion can be configured to be switchable between two positions, a guideable position where the wind direction plate can be guided to a neutral position and a guide impossible position where the wind direction plate cannot be guided to a neutral position. . As a result, it is possible to select whether the orientation of the wind direction plate deflected in the left-right direction is maintained or the neutral posture is set.

  The panel can be opened both up and down around the upper and lower axes. In an air conditioner of a type in which the panel is opened both up and down, the air blowing direction is reversed in the left-right direction at the time of switching between the upper and lower opening, and the convenience of the air conditioner is significantly reduced. Even in such a case, by providing the guide portion, it becomes possible to blow air straight out from the outlet without biasing in the left-right direction, and it is possible to avoid a decrease in convenience of the air conditioner.
