Here, the fan unit 30 intersects the wall surface portion 40a, and can be rotated from a horizontal state to a downward direction in a vertical direction around a virtual rotation axis that is aligned with a drive axis of a fan unit motor (not shown) that rotates the fan unit 30. Become. In this embodiment, the virtual rotation axis of the fan unit 30 is a horizontal axis 32.

  The outer surface of the fan unit 30 shown in FIGS. 1, 5, and 6 is positioned so that the top surface and the bottom surface are flush with the main unit 2 so that the indoor unit 11 can be seen integrally with the main unit 2 when the indoor unit 11 is stopped. The fan case 33 is arranged and the back side is semicircular when viewed from the side. The fan case 33 includes a first fan case 34 that forms the front panel 22 side, and a second fan case 35 that covers the first fan case 34 and forms the air conditioning room R side of the fan case 33. A side surface of the second fan case 35 is provided with an auxiliary suction port 36 formed of a sheet metal in which round holes are uniformly punched. An auxiliary air outlet 37 is provided on the front side of the fan case 33. The auxiliary air outlet 37 is opened in a strip shape whose height is aligned with the height of the suction grille 23.

  Between the first fan case 34 and the side wall surface 22a of the front panel 22 constituting the side surface of the main body unit 12 and the wall surface portion 40a of the side surface cover 40 in order to avoid contact with the main body unit 12 when the fan unit 30 rotates. Is provided with a gap S1.

  The fan unit 30 includes a sirocco fan type second blower fan (not shown) and a second fan motor that rotates the second blower fan, and blows air blown from the second blower fan to the auxiliary blower outlet 37. A fan casing 39 forming a path 39a is provided. The second blower fan sucks room air from the auxiliary suction port 36 through the blower passage 39a and blows it out from the auxiliary blower outlet 37 by driving the second fan motor.

  In addition, a fan unit motor (not shown) for driving the fan unit 30 is also provided therein, and the fan unit motor causes the fan unit 30 to rotate around the horizontal axis 32 up to 60 degrees in the vertical direction as shown in FIG. Can do.

  As shown in FIG. 1, the suction grille 23 of the main unit 12 includes a gentle inclined surface 23 a that is inclined from the front surface to the left and right side surfaces and gradually inclined toward the rear surface. And the front side of the fan case 33 also inclines according to the inclined surface 23a. Referring to FIG. 7, the second fan case 35 side is deeper on the back side than the first fan case 34 side in the auxiliary air outlet 37.

  The end face 34a of the first fan case 34 located at the auxiliary air outlet 37 is provided with a notch 34b cut out so as not to contact when a wind direction device 50 described later with reference to FIG. Moreover, the end surface 35a of the 2nd fan case 35 has the inclined surface 35b which inclines toward the inner side so that it may not contact when the wind direction apparatus 50 rotates right and left.

  The auxiliary air outlet 37 is provided with a wind direction device 50 that is pivotally supported by the auxiliary air outlet 37 and rotates left and right during operation. As shown in FIGS. 6 to 8, the wind direction device 50 includes a first wind direction plate 51 that covers the auxiliary air outlet 37 in a single plate shape and extends toward the main unit 12 and overlaps the front panel 22. The first wind direction plate 51 is located in front of the auxiliary air outlet 37, is gently curved in accordance with the inclined surface 23a of the suction grille 23 and has the same height as the suction grille 23 as shown in FIGS. The design is such that it can be seen as a continuous surface with the suction grille 23.

  On the back side of the first wind direction plate 51, a second wind direction plate 52 is provided that is parallel to the first wind direction plate 51, has the same height, and is shorter than the first wind direction plate 51. The first wind direction plate 51 and the second wind direction plate 52 are connected by a shaft plate 53 at the lower end. The shaft plate 53 includes a shaft 54 that extends downward.

  Moreover, it has the horizontal plate-shaped support plate 55 which connects the center of the 1st wind direction board 51 and the 2nd wind direction board 52. As shown in FIG. The support plate 55 has an arc 55a that swells on the back side of the second wind direction plate 52, and has a mountain shape that is connected to the end of the arc 55a with a width matching the auxiliary air outlet 37 on the back side of the first wind direction plate 51. It also has a role of a wind direction plate that blows up and down the air blown from the unit 30.

  A motor housing portion 56 that houses a motor (not shown) of the wind direction device 50 is provided at the upper end of the second wind direction plate. The wind direction device 50 is axially supported on the auxiliary air outlet 37 by a motor shaft and a shaft 54 provided in the motor of the fan case 33. Then, by driving the motor, from the operation stop state of FIG. 6 to the operation state of FIG. 7 from the operation stop state of FIG. 6 to the operation state of FIG. Rotate. The air blown out by being controlled by the large plate-shaped first wind direction plate 51 is blown out toward the air conditioning room R.

  The first wind direction plate 51 shown in FIG. 6 covers the auxiliary air outlet 37 and covers the gap S1, and further extends to the main unit 12 side and overlaps the front panel 22 of the main unit 12. As a result, the gap S1 is hidden from the line of sight N1 of the user of the air conditioning room R.

  Furthermore, referring to FIG. 3, the suction grille 23 of the main unit 12 has a left and right width W1 so that the first wind direction plate 51 of the fan unit 30 does not hit the first wind direction plate 51 when it overlaps the front panel 22. The front panel 22 is formed narrower than the left and right width W2.

  Further, in order to close the gap S2 formed at the joint between the first wind direction plate 51 and the suction grille 23, the front panel 22 is provided with a protruding portion 22b having a side wall surface 22a protruding forward. Since the protrusion 22b has a width W3 wider than the gap S2, the gap S2 becomes inconspicuous, and the suction grille 23 of the main unit 12 and the first wind direction plate 51 of the fan unit 30 appear to be a continuous plane.

  Further, the protrusion 22b also has a role of suppressing the rotation of the first wind direction plate 51 by applying the tip 51a of the first wind direction plate 51 to the protrusion 22b when the operation is stopped from the operation.

  When the wind direction device 50 is pivotally supported by the auxiliary air outlet 37, the first wind direction plate 51 is disposed in front of the second fan case 35. Then, the first wind direction plate 51 rotates so that the end portion 51 b on the second fan case 35 side opposite to the tip end portion 51 a moves into the auxiliary air outlet 37. The second fan case 35 is provided with an inclined surface 35b that is inclined inward to prevent contact in accordance with the trajectory of the rotation of the first wind direction plate 51. Therefore, when the fan unit 30 is viewed from the side when the wind direction device 50 closes the auxiliary air outlet 37 as shown by the user's line of sight N2 in FIG. 6, a gap S3 is formed between the first wind direction plate 51 and the second fan case 35. The inside of the auxiliary outlet 37 is visually recognized.

  Therefore, the second wind direction plate 52 is disposed in parallel to the first wind direction plate and inside the auxiliary air outlet 37. And the front-end | tip part 52a near the 2nd fan case 35 of the 2nd wind direction board 52 is located on the virtual line 35c which extended the inclined surface 35b of the 2nd fan case 35. As shown in FIG. Alternatively, it is positioned closer to the second fan case 35 than on the virtual line 35c. As a result, the second wind direction plate 52 is blinded to block the gap S3 from the inside of the fan unit 30, so that the inside of the auxiliary air outlet 37 is not visually recognized.

  When the indoor unit 11 is operated, the wind direction device 50 rotates about the shaft 54 as a rotation axis as shown in FIG. For example, when air is blown in the front direction, the first wind direction plate is rotated to a position where it is parallel to the fan case 33. At this time, the second wind direction plate 52 is parallel to the first wind direction plate 51 to guide air in the front direction, and also plays a role of hiding the inside of the auxiliary air outlet 37 from the user's line of sight N3 from the front. Even during operation, the inside of the auxiliary air outlet 37 cannot be seen.

  Next, effects of the fan units 30 and 31 will be described. When the indoor unit 11 starts operation, as shown in FIG. 4, the upper wind direction plate 20 a and the lower wind direction plate 20 b rotate and suck the air that has been sucked from the suction port 16 and exchanged heat with the refrigerant to generate cold air or warm air. While blowing out to the air conditioning room R, the fan units 30 and 31 rotate around the horizontal axis 32. At that time, the auxiliary air outlet 37 is also displaced up and down, and the direction of the air flow blown out from the auxiliary air outlet 37 can be changed. The wind direction device 50 of the auxiliary outlet 37 can deflect the direction of the airflow blown from the auxiliary outlet 37 in the horizontal direction by being displaced by a motor.

  For example, when the cooling operation is set, as shown in FIG. 9 (a), the cold air CA that is heat-exchanged from the main unit 12 and blown in the horizontal direction by the wind direction plate 20 is gradually lowered because it is heavier than the room air. . In that case, the fan units 30 and 31 are directed downward from the air outlet 17 to suck air from the auxiliary air inlet 36 and blow out downward from the auxiliary air outlet 37. By the flow of the air A1 blown out from the auxiliary air outlet 37, the cold air CA does not descend immediately but blows widely into the air conditioning room R, and the user M can be given a pleasant cool feeling by not being directly exposed to the cold air. .

  When the heating operation is set, as shown in FIG. 9 (b), the warm air WA exchanged in heat from the main unit 12 and blown downward by the wind direction plate 20 gradually rises because it is lighter than the room air. . In that case, the fan units 30, 31 are directed upward from the air outlet 17, and air is sucked from the auxiliary air inlet 36, and blown upward from the auxiliary air outlet 37. Due to the flow of air A2 blown out from the auxiliary air outlet 37, the warm air WA does not immediately rise but blows widely into the air conditioning room R, and the user M can get a comfortable warm feeling with his feet warmed up.

  When the air conditioner stops operation, the fan units 30 and 31 rotate upward to return to the operation stop position shown in FIG. Then, the first wind direction plate 51 of the wind direction device 50 is closed. In this state, the gap S <b> 1 between the main unit 12 and the fan units 30 and 31 is not visually recognized because it is covered with the first wind direction plate 51. Further, the gap S3 of the auxiliary air outlet 37 is not visually recognized because the second wind direction plate 52 is blinded and closed from the inside of the fan unit 30. Since the first wind direction plate 51 is seen as a flat surface continuous with the suction grille 23, the design is excellent in beauty.

  When the operation of the air conditioner is stopped, the fan units 30 and 31 are always present at the positions shown in FIG. 1 and the first wind direction plate 51 is closed. However, the fan units 30 and 31 may be moved even when the first wind direction plate 51 is closed manually by maintenance of the filter cleaning unit 25 inside the indoor unit 11 or cleaning of the indoor unit 11. In this case, since the front end portion 51a of the first wind direction plate 51 extends toward the main unit 12, the first wind direction plate 51 is located below the suction grille 23 of the main unit 12 when rotated downward. There is a possibility of damage due to collision with the front panel 22. Therefore, as shown in FIG. 10, the upper end of the front panel 22 in contact with the lower end of the suction grille 23 of the main unit 12 is located on the rear side of the suction grille 23 and the first wind direction plate 51, and gradually moves downward toward the front side. An inclined surface 26 that is inclined to the side is provided.

  When the fan unit 30 is rotated downward with the first wind direction plate 51 closed, the lower end surface 51a1 on the back side of the tip 51a of the first wind direction plate 51 gradually moves forward along the inclined surface 26. Moving. As a result, the first wind direction plate 51 is naturally opened. And as shown in FIG. 11, the lower end surface 51a1 of the 1st wind direction board 51 opened a little gets over the inclined surface 26, and rotates below. Thereby, damage to the first wind direction plate 51 can be avoided.

  The inclined surface 26 may be provided on the front panel 22, but in this embodiment, the inclined surface 26 is provided on a decorative plate 28 combined with the front panel 22. The decorative board 28 is provided at the lower part of the suction grille 23 in accordance with the width W2 of the front panel 22, and has a metallic finish with a mirror finish on the surface. By providing the inclined surface 26 on the decorative plate 28 that has been subjected to metallic processing, the inclined surface 26 reflects light and brings a sense of quality to the indoor unit 11. When the fan unit 30 is rotated downward with the first wind direction plate 51 closed by the mirror finish, the lower end surface 51a1 on the back side of the front end portion 51a of the first wind direction plate 51 may move smoothly forward. it can.

  In addition, the indoor unit 11 includes a display unit 29 that displays an operation state by light emission of an LED lamp on the bottom surface 23b of the lower end of the suction grille 23 as shown in FIG. The display unit 29 notifies the operation state by the difference in the color of emitted light, such as the operation lamp is green, the timer lamp is orange, and the high power lamp is yellow. The emitted light is reflected by the inclined surface 26 of the decorative plate 28 that has been subjected to metallic processing, so that the color of the emitted light can be visually recognized even from a distance, and the driving state can be recognized.

  The fan units 30 and 31 are also provided with a decorative plate 38 that has been subjected to the same metallic treatment as the decorative plate 28 so as to be aligned with the decorative plate 28 when operation is stopped. As a result, the decorative plates 28 and 38 seem to be continuously connected to the entire width of the indoor unit 11, giving a sense of quality to the entire indoor unit 11.

  As described above, in the air conditioner 1 having the rotating fan units 30 and 31, the fan units 30 and 31 cover the auxiliary air outlet 37 and extend toward the main unit 12 and overlap the front panel 22. The first wind direction plate 51 is provided with a plate 51, and the front panel 22 is provided with an inclined surface 26 whose upper end is located on the back side of the first wind direction plate 51 and gradually inclines toward the front side downward. The lower end surface 51a1 on the back surface side of the front end portion 51a gradually moves forward along the inclined surface 26. As a result, the first wind direction plate 51 is naturally opened. And the lower end surface 51a1 of the 1st wind direction board 51 opened a little gets over the inclined surface 26, and rotates below. Thereby, it becomes the air conditioner 1 which can avoid the failure | damage of the 1st wind direction board 51. FIG.
