Accordingly, for example, a part of the airflow can be prevented from flowing in an upward direction without being deflected in a downward direction when the vertical blade (7) is tilted toward the downward direction to deflect the direction of the airflow and the airflow passes through the vertical blade (7), thereby improving the controllability of the airflow.

Description

    BACKGROUND OF THE INVENTION 1. Field of the Invention
  • The present invention relates to an air conditioner having a vertical blade that is disposed at an outlet, and deflects the direction of an airflow which is generated by a fan in an upward or downward direction.
  • 2. Description of the Related Art
  • Up to now, there has been known an air conditioner having a case in which an air passage that communicates with an inlet and an outlet is formed, a fan that is disposed within the air passage and generates an airflow, and a vertical blade that is disposed at the outlet and deflects the direction of the airflow blown out of the outlet in the upward or downward direction (for example, refer to JP 03-158 647 A ).
  • The air conditioner turns the vertical blade in a horizontal direction or a downward direction to control the direction of the airflow in the horizontal direction or the downward direction.
  • However, in the above-mentioned air conditioner, for example, when the vertical blade is tilted in the downward direction to deflect the direction of the airflow in the downward direction, a part of an airflow that passes through an upper surface of the vertical blade is caused to flow in the upward direction without being deflected in the downward direction when the airflow passes through the vertical blade. This causes a problem that the controllability of the airflow is deteriorated.
  • SUMMARY OF THE INVENTION
  • The present invention has been made to solve the above-mentioned problem, and therefore an object of the present invention is to provide an air conditioner that, for example, prevents a part of airflow from flowing in the upward direction without being deflected in the downward direction when the vertical blade is tilted toward the downward direction in order to deflect the direction of airflow and the airflow passes through the vertical blade, thereby improving the controllability of the airflow.
  • The air conditioner according to the present invention includes:
    • a case having an air passage that communicates with an inlet and an outlet therein;
    • a fan that is disposed within the air passage and generates an airflow;
    • a first rotating shaft that is rotatably disposed in the outlet and extends toward a side surface that bounds the outlet;
    • a vertical blade that is disposed in the outlet, and rotates about the first rotating shaft to deflect a direction of the airflow blown out of the outlet in an upward or downward direction; and
    • a vertical blade driving means that is disposed between the first rotating shaft and the vertical blade, changes a relative position between the first rotating shaft and the vertical blade, and rotates the vertical blade about the first rotating shaft.
  • According to the air conditioner of the present invention, for example, a part of airflow is prevented from flowing in the upward direction without being deflected in the downward direction when the vertical blade is tilted toward the downward direction to deflect the direction of airflow and the airflow passes through the vertical blade, thereby improving the controllability of the airflow.

  • The air conditioner according to this embodiment includes a case 4 in which an inlet 1 for sucking air from the outside, an outlet 2 for blowing out the air sucked from the inlet 1 to the outside, and an air passage 3 for communicating the inlet 1 and the outlet 2, formed therein.
  • Also, this air conditioner includes a fan 5 that is disposed within the air passage 3 and generates an airflow, a heat exchanger 6 that is disposed between the inlet 1 and the fan 5 and exchanges heat with the air which has been sucked in from the inlet 1, a vertical blade 7 having a circular arc cross section which is disposed at the outlet 2 and deflects the direction of an airflow which is blown out of the outlet 2 in an upward or downward direction, and a horizontal blade 8 that is disposed between the fan 5 and the vertical blade 7 and deflects the direction of an airflow within the air passage 3 in a rightward or leftward direction.
  • A slide motion rotating shaft 9 that is a first rotating shaft which extends toward side surfaces which bound the outlet 2 in the horizontal direction is rotatably disposed in the outlet 2.
  • A slide motion motor (not shown) that is controlled by a control unit (not shown) is connected to the slide motion rotating shaft 9 through a link mechanism (not shown), and the slide motion rotating shaft 9 rotates due to the drive of the slide motion motor.
  • A box connector main body 10a having a cavity formed inside is disposed at an end of the side surface that bounds the outlet 2 on one surface of the vertical blade 7.
  • A support 10b that is U-shaped in cross section, and slidably supports the end of the vertical blade 7 is disposed on a lower side of the connector main body 10a.
  • The connector 10 is constituted by the connector main body 10a and the support 10b.
  • A through-hole is formed in the side surface of the connector main body 10a that faces the side surface which bounds the outlet 2, and a first bearing 11 is fitted into the through-hole.
  • The slide motion rotating shaft 9 is rotatably supported by the first bearing 11, and the end of the slide motion rotating shaft 9 faces the interior of the connector main body 10a.
  • Also, the connector main body 10a has both side surfaces of the slide motion rotating shaft 9 in the axial direction, through-holes are formed at the vertical blade 7 side with respect to the first bearing 11, and second bearings 12 are fitted into the respective through-holes.
  • A transmission rotating shaft 13 having both ends rotatably supported by the second bearing 12 is fitted to the inner side of the connector main body 10a so as to be in parallel to the slide motion rotating shaft 9.
  • A first gear 14 that is fixed to the slide motion rotating shaft 9 and rotates together with the slide motion rotating shaft 9 is disposed inside of the connector main body 10a.
  • Also, a second gear 15 that is a rotating body which is fixed to the transmission rotating shaft 13, rotates with the transmission rotating shaft 13, and is meshing with the first gear 14 is disposed inside of the connector main body 10a.
  • The first gear 14 and the second gear 15 are made of a resin, but are not limited to this material, and any material with enough strength such as metal may be used instead.
  • A surface of the vertical blade 7 which faces the connector main body 10a is formed with convex portions 7a which are an engaged portion which can be meshing with the second gear 15.
  • A plurality of convex portions 7a are aligned in a direction orthogonal to the transmission rotating shaft 13.
  • The connector 10 houses the first gear 14 and the second gear 15 inside of the connector main body 10a that is a box having a cavity inside so as to prevent dust in the air from being attached to the first gear 14 and the second gear 15, and dew condensation from occurring on the first gear 14 and the second gear 15. However, if there arises no problem of dust in the air being attached to the first gear 14 and the second gear 15, or dew condensation occurring on the first gear 14 and the second gear 15, the connector main body 10a may not be boxy.
  • In this case, the connector main body 10a is configured in such a manner that the first bearing 11 and the second bearing 12 can be fitted to the connector main body 10a.
  • A third gear 16 having an interior into which the slide motion rotating shaft 9 penetrates is fixed to the outer side of the side wall to which the first bearing 11 of the connector main body 10a is fitted.
  • With the above-mentioned configuration, when the third gear 16 rotates about the slide motion rotating shaft 9, the connector 10 also rotates about the slide motion rotating shaft 9 in conjunction with the third gear 16.
  • A fourth gear 18 that is fixed to a rotation motion rotating shift 17 which is a second rotating shaft which is disposed in parallel to the slide motion rotating shaft 9 is meshing with the third gear 16.
  • The rotation motion rotating shaft 17 is connected with a rotation motion motor (not shown) through a link mechanism (not shown), and the rotation motion rotating shaft 17 rotates due to the drive of the rotation motion motor.
  • The fourth gear 18 rotates in conjunction with the rotation of the rotation motion rotating shaft 17, the third gear 16 rotates, and the connector 10 rotates about the slide motion rotating shaft 9.
  • The vertical blade driving means 19 is formed of the slide motion rotating shaft 9, the first gear 14, the transmission rotating shaft 13, the second gear 15, the connector 10, the convex portion 7a, the third gear 16, the rotation motion rotating shaft 17, and the fourth gear 18.
  • Subsequently, the operation of the air conditioner according to this embodiment will be described below.
  • First, a description will be given of a case where changing over from a stop state to a state where the airflow is blown out of the outlet 2 in the horizontal direction.
  • Fig. 5A is an explanatory diagram showing the outlet 2 when the air conditioner shown in Fig. 1 is in a stop state, and Fig. 5B is a diagram showing the vertical blade driving means 19 shown in Fig. 5A. Fig. 6A is an explanatory diagram showing the outlet 2 when the air conditioner shown in Fig. 1 blows the airflow from the outlet 2 in the horizontal direction, and Fig. 6B is a diagram showing the vertical blade driving means 19 shown in Fig. 6A.
  • In the state where the air conditioner stops, the vertical blade 7 is so tilted as to close the outlet 2.
  • In this state, when the air conditioner is operated by a user so as to blow the airflow in the horizontal direction, the airflow occurs due to the rotation of the fan 5, the air is sucked in from the inlet 1, and the sucked air passes through the heat exchanger 6.
  • Since the temperature of the heat exchanger 6 is controlled to a given temperature, the air that has passed through the heat exchanger 6 reaches a setting temperature, and is then carried to the outlet 2.
  • Subsequently, the slide motion motor is driven, the slide motion rotating shaft 9 rotates counterclockwise which is a direction indicated by an arrow 20a, and the first gear 14 that is fixed to the slide motion rotating shaft 9 rotates about the slide rotation rotating shaft 9 counterclockwise.
  • Also, the second gear 15 that is meshing with the first gear 14 rotates about the transmission rotating shaft 13 clockwise that is a direction indicated by an arrow 21a.
  • As a result, the vertical blade 7 that is meshing with the second gear 15 moves downstream of the slide motion rotating shaft 9 which is a direction indicated by an arrow 22a.
  • Then, the rotation motion motor is driven, the rotation motion rotating shaft 17 rotates clockwise, and the fourth gear 18 that is fixed to the rotation motion rotating shaft 17 rotates about the rotation motion rotating shaft 17 clockwise.
  • Also, the third gear 16 that is meshing with the fourth gear 18 rotates about the slide motion rotating shaft 9 counterclockwise, and the connector 10 that is fixed to the third gear 16 rotates about the slide motion rotating shaft 9 counterclockwise.
  • As a result, the vertical blade 7 that is supported by the connector 10 rotates about the slide motion rotating shaft 9 counterclockwise that is a direction indicated by an arrow 23a.
  • The vertical blade 7 rotates so as to be directed in the horizontal direction, and the downstream end of the vertical blade 7 moves toward a downstream side which is a direction away from the slide motion rotating shaft 9. With the above-mentioned operation, even if the vertical blade 7 or the horizontal blade 8 is upsized, the upstream side end of the vertical blade 7 can be prevented from colliding with the horizontal blade 8.
  • As a result, the controllability of the airflow when the vertical blade 7 is tilted in the horizontal direction can be improved.
  • Subsequently, a description will be given of a case of changing over from the stop state to a state where the airflow is blown out of the outlet 2 in the downward direction.
  • Fig. 7A is an explanatory diagram showing the outlet 2 when the air conditioner shown in Fig. 1 blows the airflow from the outlet 2 in the downward direction, and Fig. 7B is a diagram showing the vertical blade driving means 19 of Fig. 7A.
  • When the air conditioner is operated by a user so as to blow the airflow in the downward direction from a state where the vertical blade 7 closes the outlet 2, the airflow occurs due to the rotation of the fan 5, and the air that has been sucked in from the inlet 1 passes through the heat exchanger 6, and is then carried to the outlet 2.
  • Subsequently, the slide motion motor is driven, the slide motion rotating shaft 9 rotates clockwise which is a direction indicated by an arrow 20b, and the first gear 14 that is fixed to the slide motion rotating shaft 9 rotates about the slide rotation rotating shaft 9 clockwise.
  • Also, the second gear 15 that is meshing with the first gear 14 rotates about the transmission rotating shaft 13 counterclockwise that is a direction indicated by an arrow 21b.
  • As a result, the vertical blade 7 that is meshing with the second gear 15 moves downstream of the slide motion rotating shaft 9 which is a direction indicated by an arrow 22b.
  • Then, the rotation motion rotating shaft 17 rotates counterclockwise by the drive of the rotation motion motor, and the fourth gear 18 that is fixed to the rotation motion rotating shaft 17 rotates about the rotation motion rotating shaft 17 counterclockwise.
  • Also, the third gear 16 that is meshing with the fourth gear 18 rotates about the slide motion rotating shaft 9 clockwise, and the connector 10 that is fixed to the third gear 16 rotates about the slide motion rotating shaft 9 clockwise.
  • As a result, the vertical blade 7 that is supported by the connector 10 rotates about the slide motion rotating shaft 9 clockwise that is a direction indicated by an arrow 23b.
  • The vertical blade 7 rotates so as to be directed in the downward direction, and the downstream end of the vertical blade 7 moves toward a downstream side which is a direction away from the slide motion rotating shaft 9. With the above-mentioned operation, even if the vertical blade 7 or the horizontal blade 8 is upsized, the upstream side end of the vertical blade 7 can be prevented from colliding with the horizontal blade 8.
  • As a result, the controllability of the airflow when the vertical blade 7 is tilted in the downward direction can be improved.
  • Also, since the upstream end of the vertical blade 7 can approach a ceiling surface of the outlet 2, a part of airflow which passes through the upper side of the vertical blade 7 can be prevented from flowing in the upward direction without being deflected, and the controllability of the airflow can be further improved.
  • As described above, according to the air conditioner of this embodiment, a relative position between the slide motion rotating shaft 9 and the vertical blade 7 is changed by the vertical blade driving means 19, and the vertical blade 7 rotates about the slide motion rotating shaft 9. As a result, for example, even if the vertical blade 7 is tilted in the downward direction so as to deflect the direction of the airflow in the downward direction, the upstream end of the vertical blade 7 approaches the ceiling surface of the outlet 2, thereby preventing a part of the airflow that passes through the upper side of the vertical blade 7 from flowing in the upward direction without being deflected. This enables the controllability of the airflow to be improved.
  • Also, the vertical blade driving means 19 inverts the vertical blade 7 in the upward or downward direction, and also changes the relative position between the slide motion rotating shaft 9 and the vertical blade 7 in a direction along which the downstream end of the vertical blade 7 is apart from the slide motion rotating shaft 9. With the above-mentioned operation, even if the vertical blade 7 or the horizontal blade 8 is upsized, the vertical blade 7 is prevented from colliding with the horizontal blade 8. This enables the controllability of the airflow to be improved.
  • Also, the vertical blade driving means 19 has the second gear 15 that comes in contact with the vertical blade 7 and rotates in conjunction with the slide motion rotating shaft 9. The second gear 15 rotates while the vertical blade 7 moves in one direction with respect to the slide motion rotating shaft 9. As a result, the turning force of the slide motion rotating shaft 9 can be transmitted to the vertical blade 7 with the simple configuration.
  • Further, since the vertical blade 7 is formed with the convex portion 7a which is meshing with the second gear 15, the turning force of the second gear 15 can be transmitted to the vertical blade 7 with a simple configuration.
  • This embodiment exemplifies the vertical blade driving means 19 having the slide motion rotating shaft 9 that is connected to the slide motion motor and the rotation motion rotating shaft 17 that is connected to the rotation motion motor. However, the present invention is not limited to this configuration. As shown in Fig. 8, the vertical blade driving means 19 can be configured in such a manner that a fifth gear 24 is fixed to the slide motion rotating shaft 9, and a sixth gear 25 that is meshing with the fifth gear 24 is fixed to the rotation motion rotating shaft 17 to rotate the slide motion rotating shaft 9 at the same time when the rotation motion rotating shaft 17 rotates.
  • Other configurations are identical with those in the first embodiment.
  • In this case, the motor can be fitted to any one of the slide motion rotating shaft 9 and the rotation motion rotating shaft 17, thereby enabling the number of motors to be reduced.
  • Fig. 9 is a diagram showing another example of the vertical blade driving means 19 of the air conditioner according to this embodiment.
  • The support 10b extends horizontally in a direction away from the connector main body 10a, then is bent toward the vertical blade 7, further bent before the vertical blade 7, and again extends horizontally in the direction away from the connector main body 10a.
  • The vertical blade 7 includes an L-shaped support receiving portion 26 having a leading end directed toward the connector main body 10a on a surface thereof that faces the connector main body 10a.
  • The leading end of the support 10b is slidably disposed inside of the support receiving portion 26.
  • With the above-mentioned configuration, the vertical blade 7 is slidably supported to the connector 10.
  • According to the above-mentioned air conditioner, it is not necessary that the support 10b is so disposed as to extend from one surface of the vertical blade 7 to another surface thereof with the result that the support 10b can be simply formed. Also, a position at which the connector 10 is fitted is not limited to the end of the side surface of the outlet 2 of the vertical blade 7, but can be freely provided.
  • Fig. 10 is a diagram showing still another example of the vertical blade driving means 19 of the air conditioner according to this embodiment.
  • A lower side of the support 10b is U-shaped in cross section.
  • The vertical blade 7 has a concave portion 27 along which the leading end of the support 10b is slidable on a surface thereof which faces the side surface that bounds the outlet 2.
  • With the above-mentioned configuration, the vertical blade 7 is slidably supported to the connector 10.
  • According to the above-mentioned air conditioner, since the support 10b does not extend up to a surface of the vertical blade 7 at an opposite side of the connector main body 10a, the surface of the vertical blade 7 at an opposite side of the connector main body 10a can further approach the ceiling surface or the bottom surface of the outlet 2.
  • Fig. 11 is a perspective view showing yet still another example of the vertical blade driving means 19 of the air conditioner according to this embodiment.
  • A surface of the vertical blade 7 which faces the connector main body 10a is formed with concave portions 7b which are an engaged portion which can be meshing with the second gear 15.
  • A plurality of concave portions 7b are continuously aligned in a direction orthogonal to the transmission rotating shaft 13.
  • Since the concave portion 7b reduces collision with the airflow as compared with the convex portion 7a, dust contained in the airflow can be prevented from being attached to the concave portion 7b.
  • As a result, the reliability in the driving of the vertical blade 7 can be improved.
  • The engaged portion is not limited to the concave portion 7b having a bottom, but can be a through-hole that penetrates the vertical blade 6.
  • Second Embodiment
  • Fig. 12 is a perspective view showing a main portion of an air conditioner according to this embodiment.

  • The first cylindrical portion 28 and the second cylindrical portion 29 have rubber which is a slip stopper member on their peripheries which come in contact with each other. When the first cylindrical portion 28 rotates, the second cylindrical portion 29 also rotates in conjunction with the first cylindrical portion 28, and the vertical blade 7 moves in one direction with respect to the second cylindrical member 29.

For this reason, the attachment of dust onto the first cylindrical portion 28, the second cylindrical portion 29, and the vertical blade 7 can be reduced as compared with the air conditioner according to the first embodiment.

  • The vertical blade driving means 34 include a connector 35 having one end rotatably supported to the slide motion rotating shaft 32 and another end supporting the vertical blade 30, a moving mechanism 36 that relatively moves the vertical blade 30 with respect to the connector 35, and a rotating mechanism 37 that rotates the connector 35 about the slide motion rotating shaft 32.
  • The connectors 35 are disposed at both ends of the vertical blade 30, respectively, and the moving mechanisms 36 and the rotating mechanisms 37 are disposed on the respective connectors 35.
  • Each of the moving mechanisms 36 includes a first rotating force transmission unit having a seventh gear 38 that is fixed to the slide motion rotating shaft 32 and rotates together with the slide motion rotating shaft 32, an eighth gear 39 that is rotatably supported to the connector 35 and meshing with the seventh gear 38, a ninth gear 40 that is rotatable and meshing with the eighth gear 39, and a transmission rotating shaft 41 which is rotatably supported by the connector 35, and whose one end is fixed to the ninth gear 40, and a tenth gear 42 that is a rotating body which is fixed to another end of the transmission rotating shaft 41.
  • The seventh gear 38, the eighth gear 39, and the ninth gear 40 are aligned from the slide motion rotating shaft 32 toward the vertical blade 30 inside of the connector 35 having a cavity therein.
  • Ring-shaped slide guides 30a that are flattened are fixed at both side surfaces that bound the outlet 2 on a surface of the vertical blade 30 which faces the slide motion rotating shaft 32.
  • Each of the slide guides 30a extends in a direction orthogonal to the slide motion rotating shaft 32, and projections 30b which are triangular first contact portions are continuously formed on a bottom surface of the interior of the slide guide 30a in the longitudinal direction.
  • These projections 30b are meshing with the tenth gear 42.
  • With the above-mentioned configuration, when the slide motion rotating shaft 32 rotates, the rotating force is transmitted to the tenth gear 42 through the seventh gear 38, the eighth gear 39, the ninth gear 40, and the transmission rotating shaft 41. As a result, the vertical blade 30 relatively moves with respect to the connector 35.
  • The above-mentioned embodiment exemplifies the vertical blade 30 having the slide guide 30a on which the projections 30b are formed. However, the present invention is not limited to the above-mentioned configuration, and the vertical blade 30 may be directly formed with the projections.
  • The rotating mechanism 37 includes an eleventh gear 43 that is a second contact portion which is fixed to the connector 35 about the slide motion rotating shaft 32, and a second rotating force transmission unit having a twelfth gear 44 that is rotatable and meshing with the eleventh gear 43, and a thirteenth gear 45 that is fixed to the rotating motion rotating shaft 33 and meshing with the twelfth gear 44.
  • The eleventh gear 43, the twelfth gear 44, and the thirteenth gear 45 are aligned from the slide motion rotating shaft 32 toward the rotation motion rotating shaft 33.
  • With the above-mentioned configuration, when the rotation motion rotating shaft 33 rotates, the rotating force is transmitted to the eleventh gear 43 through the thirteenth gear 45 and the twelfth gear 44, and the connector 35 rotates about the slide motion rotating shaft 32.
  • The eleventh gear 43 can be integrated with the connector 35.
  • The projections 30b, the seventh gear 38, the eighth gear 39, the ninth gear 40, the tenth gear 42, the eleventh gear 43, the twelfth gear 44, and the thirteenth gear 45 are made of copper-based metal. However, the present invention is not limited to the above-mentioned configuration, so these gears can be made of other materials such as iron-based metal, polyacetal resin, and nylon resin.
  • One end of the slide motion rotating shaft 32 is connected with a slide motion motor 46 which is a first motor that rotates the slide motion rotating shaft 32, and one end of the rotation motion rotating shaft 33 is connected with a rotation motion motor 47 which is a second motor that rotates the rotation motion rotating shaft 33.
  • Other configurations are identical with those in the first embodiment.
  • Subsequently, the operation of the air conditioner according to this embodiment will be described.
  • Fig. 16 is a structural diagram showing a state in which the air conditioner shown in Fig. 13 is in a stop state. Fig. 17 is a structural diagram showing a state where the air conditioner shown in Fig. 13 blows the airflow out of the outlet 2 in the horizontal direction. Fig. 18 is a structural diagram showing a state where the air conditioner shown in Fig. 13 blows the airflow out of the outlet 2 in the downward direction.
  • In a state where the air conditioner stops, the vertical blade 30 is so tilted as to close the outlet 2.
  • With the above-mentioned configuration, a simply designed structure can be provided.
  • In the above-mentioned state, when the air conditioner is operated by a user so as to conduct a heater operation, the rotation operation motor 47 is driven to rotate the rotation operation rotating shaft 33. The rotating force of the rotation operation rotating shaft 33 is transmitted to the eleventh gear 43 through the thirteenth gear 45 and the twelfth gear 44, and the connector 35 rotates about the slide motion rotating shaft 32 in such a direction that the concave portion of the vertical blade 30 is directed downwards in conjunction with the eleventh gear 43.
  • Since the airflow can be deflected in the downward direction along the concave portion of the vertical blade 30, hot air is prevented from soaring from the downstream end of the vertical blade 30 with the result that hot air arrival property in floor surface direction can be improved.
  • Also, since the vertical blade 30 rotates at a large angle, the vertical blade 30 can approach the ceiling surface of the outlet 2. Accordingly, the airflow that has passed through the upper side of the vertical blade 30 is prevented from flowing in the upward direction. As a result, it is possible to improve the controllability of the airflow.
  • Then, the slide motion motor 46 is driven to rotate the slide motion rotating shaft 32, and the rotating force of the slide motion rotating shaft 32 is transmitted to the tenth gear 42 through the seventh gear 38, the eighth gear 39, the ninth gear 40, and the transmission rotating shaft 41.
  • Since the tenth gear 42 rotates while meshing with the projections 30b, the vertical blade 30 relatively moves in a direction along which the downstream end is apart from the slide motion rotating shaft 32 with respect to the connector 35.
  • With the above-mentioned operation, the vertical blade 30 can be prevented from colliding with the horizontal blade 31 or the ceiling surface of the outlet 2.
  • Subsequently, when the air conditioner is operated by the user so as to conduct cooler operation, the rotation operation motor 47 is driven in an opposite direction to that at the time of the heater operation to rotate the rotation operation rotating shaft 33. The rotating force of the rotation operation rotating shaft 33 is transmitted to the eleventh gear 43 through the thirteenth gear 45 and the twelfth gear 44, and the connector 35 rotates about the slide motion rotating shaft 32 in such a direction that the concave portion of the vertical blade 30 is directed upwards in conjunction with the eleventh gear 43.
  • Since the airflow can be deflected in the horizontal direction along the concave portion of the vertical blade 30, cold air is prevented from blowing down the downstream end of the vertical blade 30.
  • Also, since the vertical blade 30 rotates at a large angle, the vertical blade 30 can approach the bottom surface of the outlet 2. Accordingly, the airflow that has passed through the lower side of the vertical blade 30 is prevented from flowing in the downward direction. As a result, it is possible to improve the controllability of the airflow.
  • Then, the slide motion motor 46 is driven in an opposite direction to that at the time of the heater operation to rotate the slide motion rotating shaft 32. The rotating force of the slide motion rotating shaft 32 is transmitted to the tenth gear 42 through the seventh gear 38, the eighth gear 39, the ninth gear 40, and the transmission rotating shaft 41.
  • Since the tenth gear 42 rotates while meshing with the projections 30b, the vertical blade 30 relatively moves in a direction in which the downstream end is apart from the slide motion rotating shaft 32 with respect to the connector 35.
  • With the above-mentioned operation, the vertical blade 30 can be prevented from colliding with the horizontal blade 31 or the ceiling surface of the outlet 2.
  • As described above, in the air conditioner according to this embodiment, the relative position between the slide motion rotating shaft 32 and the vertical blade 30 is changed by the vertical blade driving means 34, and the vertical blade 30 rotates about the slide motion rotating shaft 32. For this reason, for example, even if the vertical blade 30 is tilted in the downward direction so as to deflect the direction of airflow in the downward direction, the upstream end of the vertical blade 30 is made to approach the ceiling surface of the outlet 2 to prevent a part of the airflow that passes through the upper side of the vertical blade 30 from flowing in the upward direction without being deflected. As a result, the controllability of the airflow can be improved.
  • Also, the slide motion motor 46 and the vertical blade 30 can be disposed apart from each other by the first rotating force transmitting means, and the rotation motion motor 47 and the vertical blade 30 can be disposed apart from each other by the second rotating force transmitting means. For this reason, a pressure loss of the airflow within the air passage 3 due to the slide motion motor 46 or the rotation motion motor 47 can be reduced, and dew condensation that is produced by the generation of a turbulent flow can be prevented.
  • Further, the slide motion rotating shaft 32 is rotated by the drive of the slide motion motor 46, and the rotation motion rotating shaft 33 is rotated by the drive of the rotation motion motor 47. For this reason, the vertical blade 30 can be rotated in order that the vertical blade 30 does not collide with the outlet 2 or the horizontal blade 31.
  • Still further, only the slide motion motor 46 is driven, thereby making it possible to protrude the vertical blade 30 to the downstream side, or retract the vertical blade 30 to the upstream side. As a result, for example, the flow passage of the outlet 2 is narrowed to reduce the air flow, thereby making it possible to accelerate the flow rate of the airflow to extend the arrival distance of the airflow, and to further improve the controllability of the airflow.

  • The slide guide 30a is omitted in Fig. 20, the rotation motion motor 47 is omitted in Fig. 20B, and the slide motion motor 46 is omitted in Fig. 8D.
  • The slide motion motor 46 is disposed at one side surface of the outlet 2, and the rotation motion motor 47 is disposed at another side surface of the outlet 2.
  • The rotation motion rotating shaft 33 extends between the rotation motion motor 47 and one of the connectors 35 which is closer to the rotation motion motor 47, and the rotating mechanism 37 is disposed on the one connector 35.
  • The connector 35, the rotating mechanism 37, and the vertical blade 30 are made of a material having mechanical rigidity to the degree that the vertical blade 30 and another connector 35 can rotate about the slide motion rotating shaft 32 when one connector 35 rotates about the slide motion rotating shaft 32.
  • According to the above-mentioned air conditioner, the slide motion motor 46 and the rotation motion motor 47 are disposed apart from each other, the degree of freedom of the sizes of the slide motion motor 46 and the rotation motion motor 47 is improved.
  • Also, the rotation motion rotating shaft 33 extends between the rotation motion motor 47 and one of the connectors 35 which is closer to the rotation motion motor 47, and is not disposed between the respective connectors 35. As a result, the airflow that flows along the vertical blade 30 can be prevented from being obstructed by the rotation motion rotating shaft 33.

  • As a result, the vertical blade 30 relatively moves in such a direction that the downstream end is apart from the slide motion rotating shaft 32 with respect to the connector 35.
  • At the same time, the rotating force of the slide motion rotating shaft 32 is transmitted to the rotation motion rotating shaft 33 through the fourteenth gear 48 and the fifteenth gear 49.
  • When the rotation motion rotating shaft 33 rotates, the rotating force of the rotation motion rotating shaft 33 is transmitted to the eleventh gear 43 as in the air conditioner according to the third embodiment.
  • As a result, the vertical blade 30 rotates in a direction along which the concave portion is directed downwardly.
