  • the wind guide panel 20 is formed by one curved panel, so as to have a width which is the same as the width of the cabinet 3 and which is larger than the width of the blow-out port 5. Further, in the front surface of the cabinet 3, a front panel 21 is formed from the middle stage portion of the front surface to the bottom surface so as to be one stage lower than the front surface. Thereby, a recessed section is formed over the whole width direction so that the wind guide panel 20 can be fit into the recessed section. An opening is formed in the front panel 21 which forms the recessed section, and the opening serves as the blow-out port 5. Therefore, the wind guide panel 20 is located in front of the blow-out port 5, so as to cover the blow-out port 5 and the front panel 21 around the blow-out port 5. At this time, the wind guide panel 20 is held in a closed posture as shown in Figure 2 .
  • the outer surface of the wind guide panel 20 forms 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 formed as a member, which configures 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 is formed into a long panel having a total length greater than that of the louver adopted in a conventional air conditioner.
  • the wind guide panel 20 is rotated about an upper or lower shaft in the different directions so as to thereby be upwardlyly or downwardly opened.

  • the strength against deformation of the wind guide panel 20 can be increased, so that the size of the wind guide panel 20 can be increased.
  • the wind guide panel 20 is configured to be hardly deformed, and hence the curving degree of the wind guide panel 20 in the front and rear direction can be increased. Thereby, it is possible to easily perform the control of the air blowing direction at the time when the wind guide panel 20 is opened. That is, at the time of cooling operation, cool air can be guided toward the ceiling, so as to increase the reaching distance of the cool air. At the time of heating operation, warm air is guided toward the wall so as to reach the floor surface.

  • the timing of starting the opening and closing motor 86 is set after the lower hook 53 is separated from the lower shaft 22. That is, the control device 41 stops the regulating motor 70, when a predetermined first timing is reached.
  • the first timing is a timing which is determined according to the time period until the other end shaft 64b of the upper link 64 reaches the end of the upper locking groove 72a as shown in Figure 23(b) . After stopping the regulating motor 70, the control device 41 drives the opening and closing motor 86.
  • the opening and closing motor 86 When the opening and closing motor 86 is driven, the moving plate 81 is rotated counterclockwise. The rod 32 is pushed out to the front side, so that the wind guide panel 20 is moved in the direction away from the cabinet 3. The wind guide panel 20 is opened about the upper shaft 23. When the wind guide panel 20 is opened at a set opening angle, the control device 41 stops the opening and closing motor 86. Note that the opening angle is calculated from the number of steps of the opening and closing motor 86.
  • the control device 41 drives the opening and closing motor 86 for a fixed time period, and stops the opening and closing motor 86 when a second timing is reached. At this time, the opening angle reaches the maximum opening angle as shown in Figure 25 .
  • the wind guide panel 20 is held in the upwardly opened posture, so that the warm air is blown out toward the floor surface.
  • control device 41 controls the operation of the louver motor 803 so that the auxiliary louver 800 is operated to be opened at a predetermined angle. Thereby, the warm air is blown out toward the floor surface.
  • control device 41 controls the regulating motor 70 and the opening and closing motor 86 at the same timing.
  • the regulating motor 70 is rotated in the direction opposite to the direction at the time of the heating operation.
  • the opening and closing motor 86 is rotated in the same direction as the direction at the time of the heating operation.
  • the opening and closing motor 86 When the opening and closing motor 86 is driven for a fixed time period, and when the second timing is reached, the opening and closing motor 86 is stopped. At this time, the opening angle reaches the maximum opening angle as shown in Figure 26 .
  • the wind guide panel 20 is held in the downwardly opened posture, so that the cool air is blown out toward the ceiling. Thereafter, the control device 41 controls the operation of the louver motor 803 so that the auxiliary louver 800 is operated to be oriented in parallel with the flow of the wind. Thereby, the cool air is blown out toward the ceiling.
  • the control device 41 When the cooling or heating operation is ended, the control device 41 first operates the louver motor 803 so that the auxiliary louver 800 is operated to be closed. Next, the control device 41 drives the opening and closing motor 86. The rod 32 is pulled back, so that the wind guide panel 20 is made to approach the cabinet 3. The control device 41 stops the opening and closing motor 86 when a predetermined third timing is reached. At this time, as shown in Figure 24 , the wind guide panel 20 is held in the closed posture, and the moving plate 81 is positioned on the rear side. That is, the third timing is a timing which is determined according to the time period during which the moving plate 81 is returned to the initial state. Note that the position detecting sensor 90 detects that the moving plate 81 is returned to the initial state. The third timing may also be set according to the detection timing.
  • the control device 41 drives the regulating motor 70.
  • the state shown in Figure 23 (b) is changed to the state shown in Figure 23 (a) .
  • the lower hook 53 is rotated, so that the lower shaft 22 is locked.
  • the control device 41 stops the regulating motor 70 when a predetermined fourth timing is reached.
  • the fourth timing is a timing determined according to the time period during which the other end shaft 65b of the lower link 65 is moved from the connecting position between the upper locking groove 72a and the neutral groove 72b, to reach the connecting position between the neutral groove 72b and the lower locking groove 72c.
  • the engagement portion may be provided in the support material to catch and engage the wind guide panel.
  • a rotary shaft may be provided in the wind guide panel and a bearing may be provided in the support material.
  • support at three points may be provided by providing the engagement portion in the middle of the wind guide panel and the holding portions on the front side and the back side.
  • the rotary shaft of the holding portion is allowed to slide in the horizontal direction and the rotary shaft is pressed so as to be detached from the bearing, thus making it possible to perform attachment/detachment easily.
  • the panel structure described above is also applicable to an air conditioner having a structure where a support material for supporting a wind guide panel which opens and closes a blow out port is attached in a vicinity of a tip end of an arm portion so as to rotate freely (or revolve freely), which is different from the air conditioner of the present embodiment.
  • a support material for supporting a wind guide panel which opens and closes a blow out port is attached in a vicinity of a tip end of an arm portion so as to rotate freely (or revolve freely), which is different from the air conditioner of the present embodiment.
  • the rod is replaced as the arm portion and a driving component such as a gear is stored in the arm portion.
  • the driving component is driven by a motor and the support material attached to the tip end of the arm portion rotates (or revolves). Accordingly, the wind guide panel attached to the support material also rotates (or revolves).
  • the arm portion In order to rotate (or revolve) the wind guide panel, the arm portion is moved frontward from the blow out port using a motor or the like so that the tip end of the arm portion is away from a cabinet and the wind guide panel is rotated (or revolved) and controlled at a position not contacting the cabinet. Then, movement of the arm portion and rotation (or revolving) of the wind guide panel are controlled so that the wind guide panel is moved to a position where air blown out from the blow out port is able to be blown out in the horizontal direction and along a ceiling, that is, the wind guide panel is brought into the downwardly opened posture.
