During the cooling operation, the diffuser 40 rotates to a position that is substantially parallel to the slide plate 23 as shown in FIG. At this time, the up-and-down wind direction plate 19 in the blower outlet 13 is also rotated to a position substantially parallel to the slide plate 23. The lower wall 31 is extended to the front by the diffuser 40, the air passage 17 is extended to the front together with the slide plate 23, and the wind blown from the outlet 13 is blown far away. become.
During the heating operation, as shown in FIG. 4B, the diffuser 40 rotates to a position where the lower wall 31 is extended downward. At this time, the up-and-down wind direction plate 19 in the blower outlet 13 is also rotated to a position substantially parallel to the diffuser 40. The lower wall 31 is extended downward downward by the diffuser 40, and the air blowing path 17 is extended downward together with the upper and lower wind direction plates 19 so that the wind blown out from the outlet 13 is blown downward. Become.

FIG. 7A is a diagram showing the inside of the right side surface, and FIG. 7B is a partial front view of the state where the open / close panel 20 is removed. In the operation stop state of the indoor unit 1 shown in FIG. 7A, first side panels 50 are erected on the left and right ends of the open / close panel 20 from the back surface to the back surface side. In addition, second side panels 60 are erected on the left and right ends of the back surface of the diffuser 40 toward the top surface. The first side panel 50 and the second side panel 60 are flat.
The main body panel 11 includes a storage portion 70 that is inside the left side plate 112 and the right side plate 113 constituting the left and right side surfaces of the main body panel 11 and has a front door that is open and has a door pocket shape. The first side panel 50 and the second side panel 60 are stored in the storage unit 70. Thereby, the 1st side panel 50, the 2nd side panel 60, and the accommodating part 70 are not visually recognized at the time of a driving | operation stop.

  The first side panel 50 has the same height as the open / close panel 20 and is formed in a triangular shape with a narrow upper end and a wide lower end. When the operation is started and the open / close panel 20 moves forward, as shown in FIG. 2 (b), with the part on the back side remaining in the storage unit 70, it moves forward in accordance with the movement of the open / close panel 20. To do. Similarly, the second side panel 60 is formed in a fan shape that spreads forward with a radius matching the depth of the diffuser 40. When the operation is started and the diffuser 40 moves downward, a part of the top surface remains in the storage unit 70 and moves downward in accordance with the movement of the diffuser 40. As a result, the interior of the indoor unit and the storage unit 70 are not visually recognized even during operation.

As shown in FIG. 1, the indoor unit 1 has a box shape covered with the main body panel 11, the open / close panel 20, and the diffuser 40 when the operation is stopped. The blower outlet 12 is not visually recognized because it is blocked by the diffuser 40. At this time, the joints of the parts of the main body panel 11, the open / close panel 20, and the diffuser 40 are provided on the box-shaped ridge line, so that the user is not conscious of the joints of the parts.
Further, the air passage 17 can be shortened by accommodating the slide plate 23 attached to the upper wall 32 of the casing 30 forming the air passage 17 on the back side of the open / close panel 20. Thereby, the indoor unit 1 can be made smaller and more compact than before.
The small and compact indoor unit 1 looks familiar with the space of the air conditioning room. Also, by providing the part joints on the box-shaped ridgeline, it is possible to impress a design with an excellent aesthetic that does not make the part joints conscious.

When the indoor unit 1 starts operation, the opening / closing panel 20 is moved 9 ° forward by the rotating arm 21 about the rear upper corner 20a of the opening / closing panel 20 as a rotation axis. The slide plate 23 is pulled by the movement of the open / close panel 20 and moves forward along the rail 33 of the upper wall 32, so that the open / close panel 20 and the casing 30 are connected to each other so as to extend the air passage 17. Further, the first side panel 50 also moves forward as the opening / closing panel 20 moves.
When the indoor unit 1 starts operation, the diffuser 40 also rotates downward. The diffuser 40 has an action of extending the lower wall 31, and as a result, the air passage 17 is extended. As the diffuser 40 moves, the second side panel 60 also moves downward.
With this configuration, the air outlet 13 is extended by the slide plate 23 and the diffuser 40, and the side surface direction is also covered by the first side panel 50 and the second side panel 60, so that the air passage 17 is extended in a cylindrical shape. It becomes possible for the air blown out to reach farther by becoming cylindrical.
Further, the air outlet 13 is covered with the slide plate 23, the diffuser 40, the first side panel 50, and the second side panel 60. The tip of the up-and-down wind direction plate 19 is hidden by the second side panel 60 by being positioned on the housing 10 side of the fan-shaped arc end of the second side panel 60 in a side view, and the inside of the air outlet 13 is also difficult to visually recognize. Become. Since the vertical wind direction plate 19 does not appear to protrude from the housing 10, a beautiful appearance can be obtained even during driving.

  Also, as shown in FIG. 4A, the lower end 20b of the open / close panel 20 moves forward, so that a space is created in front of the front heat exchanger 151 between the back surface of the open / close panel 20 and the housing 10. A ventilation path S is formed. The air sucked from the suction port 12 by the ventilation path S can be guided to the lower part of the front heat exchanger 151, and the efficiency of the heat exchanger of the air conditioner can be increased.

  Moreover, the lower end 20b of the open / close panel 20 moves forward and the air passage 17 is extended by the slide plate 23, so that the distance between the outlet of the blower outlet 13 and the suction inlet 12 becomes longer than the conventional example. Moreover, since the air blown out from the blower outlet 13 is suppressed by the slide plate 23, it becomes difficult to move upward, and there is an effect of preventing a shortcut.
