  The end face 34a of the first fan case 34 located at the auxiliary air outlet 37 is provided with a notch 34b cut away so as not to contact when the wind direction device 50 described later with reference to FIG. Further, the end face 35a of the second fan case 35 has an inclined surface 35b which is inclined inward so that the wind direction device 50 does not contact when the wind direction device 50 rotates left and right.

  The auxiliary blower outlet 37 is provided with a wind direction device 50 which is vertically supported by the auxiliary blower outlet 37 and pivots left and right during operation. The wind direction apparatus 50 is provided with the 1st wind direction board 51 which extends in the main body unit 12 side and overlaps with the front panel 22 by the plate shape of 1 sheet, as shown to FIGS. 6-8. The first wind direction plate 51 is located forward of the auxiliary outlet 37, and gently curved according to the inclined surface 23a of the suction grille 23 as shown in FIGS. 1 and 3 and has the same height as the suction grille 23 The design makes it appear as a continuous surface with the suction grille 23.

  A second wind direction plate 52 parallel to the first wind direction plate 51 and having the same height and a shorter width than the first wind direction plate 51 is provided on the back side of 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 is provided with a shaft 54 extending downward.

  In addition, it has a horizontal plate-like support plate 55 connecting the centers of the first wind direction plate 51 and the second wind direction plate 52. The support plate 55 has an arc 55a that bulges more to the rear side than the second air direction plate 52, and has a mountain shape in which the end of the arc 55a and the rear side of the first air direction plate 51 It also plays the role of a wind direction plate that blows the air blown out from the unit 30 up and down.

  At the upper end of the second wind direction plate, there is provided a motor storage portion 56 for storing the motor (not shown) of the wind direction device 50. The wind direction device 50 is vertically supported at the auxiliary outlet 37 by a motor shaft provided on the motor in the fan case 33 and the shaft 54. Then, from the operation stop state of FIG. 6 with the shaft 54 as the rotation axis by the drive of the motor to the operation state of FIG. 7, the tip 51 a of the first wind direction plate 51 goes from the main unit 12 side to the outside of the air conditioning chamber R side. To rotate. The air that is controlled and blown out by the single large plate-like first air direction plate 51 is blown out toward the air conditioning room R.

  The first air 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 to overlap the front panel 22 of the main unit 12. Thus, the gap S1 is hidden from the line of sight N1 of the user of the air conditioning room R.

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

  Further, in order to close the gap S2 formed at the joint between the first air flow direction plate 51 and the suction grille 23, the front panel 22 is provided with a protrusion 22b in which a side wall surface 22a protrudes forward. The protrusion 22b has a width W3 larger than the gap S2, so that the gap S2 becomes inconspicuous, and the suction grille 23 of the main unit 12 and the first air direction plate 51 of the fan unit 30 appear as a continuous plane.

  The projecting portion 22 b also has a role of suppressing the rotation of the first air direction plate 51 by bringing the tip portion 51 a of the first air direction plate 51 into contact with the protruding portion 22 b at the time of operation to operation stop.

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

  Therefore, the second air direction plate 52 is disposed in parallel to the first air direction plate and inside the auxiliary outlet 37. The tip 52 a of the second air direction plate 52 near the second fan case 35 is positioned on an imaginary line 35 c in which the inclined surface 35 b of the second fan case 35 is extended. Alternatively, it is positioned closer to the second fan case 35 than on the imaginary line 35 c. As a result, the second air direction plate 52 is blinded and the gap S3 is blocked from the inside of the fan unit 30, so the inside of the auxiliary air outlet 37 is not visually recognized.

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

  Next, the 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 are sucked from the suction port 16 and exchange heat with the refrigerant to cool or warm air. While blowing into 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 vertically displaced, 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 be displaced by a motor so that the direction of the air flow blown out from the auxiliary outlet 37 can be deflected in the horizontal direction.

  For example, when the cooling operation is set, as shown in FIG. 9A, the cold air CA, which is heat-exchanged from the main unit 12 and blown out horizontally by the wind direction plate 20, is heavier than room air and gradually descends. . In that case, the fan units 30 and 31 are directed lower than the air outlet 17 to suck air from the auxiliary air inlet 36 and blow out from the auxiliary air outlet 37 downward. By the flow of the air A1 blown out from the auxiliary outlet 37, the cool air CA is widely blown to the air conditioning room R without immediately falling, and the user M can be given a comfortable cool feeling by not directly hitting the cold air. .

  When the heating operation is set, as shown in FIG. 9 (b), the warm air WA which is heat exchanged from the main unit 12 and blown downward by the wind direction plate 20 gradually rises because it is lighter than the indoor air. . In that case, the fan units 30 and 31 are directed above the air outlet 17 to suck air from the auxiliary air inlet 36 and blown upward from the auxiliary air outlet 37. By the flow of the air A2 blown out from the auxiliary outlet 37, the warm air WA is widely blown to the air conditioning room R without rising immediately, and the user M can get a warm feeling with a warm foot.

  When the air conditioner stops its operation, the fan units 30, 31 rotate upward and 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 viewed by being covered by the first air direction plate 51. Further, the gap S3 of the auxiliary air outlet 37 is not visually recognized because the second air direction plate 52 is blinded and closed from the inside of the fan unit 30. The first wind direction plate 51 can be seen as a flat surface continuous with the suction grille 23, so that the first wind direction plate 51 has an aesthetically superior design.

  In the operation stop state of the air conditioner, the fan units 30, 31 are always in the position shown in FIG. 1 and the first air direction plate 51 is closed. However, due to maintenance of the filter cleaning unit 25 inside the indoor unit 11 or cleaning of the indoor unit 11, the fan units 30 and 31 may be moved by hand even when the first air direction plate 51 is closed. In this case, since the tip 51a of the first air direction plate 51 extends to the main body unit 12 side, the first air direction plate 51 is lower than the suction grille 23 of the main body unit 12 when it is rotated downward. The collision with the front panel 22 may cause damage. 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 positioned on the back side of the suction grille 23 and the first air direction plate 51, An inclined surface 26 is provided which slopes to the side.

  When the fan unit 30 is to be rotated downward while the first air direction plate 51 is closed, the lower end surface 51a1 of the back side of the tip 51a of the first air direction plate 51 is gradually moved forward along the inclined surface 26 Moving. Thereby, 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 over the inclined surface 26, and rotates below. Damage to the first wind direction plate 51 can thereby be avoided.

  The inclined surface 26 may be provided on the front panel 22, but in the present embodiment, it is provided on the decorative plate 28 combined with the front panel 22. The decorative plate 28 is provided under the suction grille 23 in accordance with the width W2 of the front panel 22, and is subjected to metallic processing whose surface is mirror-finished. By providing the inclined surface 26 on the metallically processed decorative plate 28, the inclined surface 26 reflects light to bring the indoor unit 11 with a sense of luxury. When the fan unit 30 is turned downward with the first air direction plate 51 closed by mirror finish, the lower end surface 51a1 on the back side of the tip portion 51a of the first air direction plate 51 smoothly moves forward. it can.

  Further, as shown in FIG. 12, the indoor unit 11 is provided with a display unit 29 for displaying the operating state by the light emission of the LED lamp on the bottom surface 23b of the lower end of the suction grille 23. The display unit 29 indicates the operation state by the difference in color of light emitted, such as the operation lamp is green, the timer lamp is orange, and the high power lamp is yellow. Then, the emitted light is reflected by the inclined surface 26 of the decorative plate 28 subjected to the metallic processing, so that the color of the emitted light can be visually recognized even from a distance, and the operating state can be recognized.

  Further, the fan units 30 and 31 are also provided with a decorative plate 38 which is subjected to the same metallic processing as the decorative plate 28 so as to be aligned with the decorative plate 28 when the operation is stopped. As a result, the decorative plates 28 and 38 appear to be continuously connected to the entire width of the indoor unit 11, giving the entire indoor unit 11 a high-class feeling.

  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 outlet 37 and extend toward the main unit 12 side, and the first wind direction overlaps the front panel 22. By providing the plate 51, the gap S1 between the fan units 30, 31 and the main unit 12 to which the fan units 30, 31 are attached is concealed from the user's line of sight N1 so that the integrated air conditioner 1 can be seen. It becomes an air conditioner with improved design.
