The electrical component box 21 is disposed in the control system unit 11B in the indoor unit body 11. Various electrical components are accommodated inside the electrical component box 21. The electric components housed in the electric component box 21 include a fan motor 19 that rotates the sirocco fan 18, a control circuit that controls driving of a compressor (not shown) of the refrigeration cycle including the heat exchanger 16, and the like. In the indoor unit body 11, a pipe fixture 26 is provided for fixing a pipe constituting the refrigeration cycle including the heat exchanger 16.

  The casing 14 is provided with a sirocco fan accommodating portion 31 and an outlet connection portion 33. The sirocco fan accommodating portion 31 is provided as a substantially cylindrical space. In the sirocco fan accommodating part 31, the sirocco fan 18 is rotatably arrange | positioned. The blower outlet connection part 33 is connected to the upper part of the sirocco fan accommodating part 31, and is connected to the blower outlet 41 provided in the one surface of the indoor unit main body 11, and the lower surface of the indoor unit main body 11 in this case. In this case, the air outlet 41 extends along the left-right direction of the indoor unit body 11 on the lower surface of the indoor unit body 11.

  The air sucked from the suction port 25 by the blowing action by the sirocco fan 18 flows in the sirocco fan accommodating portion 31 and the blower outlet connection portion 33 and is blown out from the blower outlet 41 to the outside of the indoor unit body 11. In the air outlet 41, a louver 42 that adjusts the air direction of the air blown out from the air outlet 41 is provided so as to be rotatable in the vertical direction in this case. In addition, you may provide the louver in the blower outlet 41 in the left-right direction.

  By the sirocco fan accommodating part 31 and the blower outlet connection part 33, the ventilation path 51 from the suction inlet 25 to the blower outlet 41 is formed in the indoor unit main body 11. Therefore, the sirocco fan 18 is provided in the air blowing path 51, in this case, in the sirocco fan accommodating portion 31 that constitutes a part of the air blowing path 51.

  Next, the internal configuration of the indoor unit 10 will be described in more detail. In the configuration example of the indoor unit 10 described above, the suction port 25 is provided on the front surface of the indoor unit body 11, and the air outlet 41 is provided on the lower surface of the indoor unit body 11. Then, as illustrated in FIG. 4, the indoor unit main body 11 is bounded by the left and right center line L of the air outlet 41 when viewed from the front surface side, in this case, the front surface side of the indoor unit main body 11. Is divided into the left region RA and the right region RB, the sirocco fan 18 is entirely within the left region RA.

  On the other hand, the electrical component box 21 is entirely within the right region RB. That is, the electrical component box 21 is provided in a region RB on the opposite side to the region RA in which the entire sirocco fan 18 is accommodated in the left region RA and the right region RB.

  Further, the blower outlet connection part 33 is inclined with respect to the blower outlet 41 at the outer wall part 33 a that is the wall part opposite to the sirocco fan 18. The inclination of the outer wall 33a is such that the angle α formed by the straight line P orthogonal to the direction in which the air outlet 41 extends, that is, the left-right direction of the indoor unit body 11, and the tangent line Q of the outer wall 33a is 20 degrees to 50 degrees. It is preferable to set the inclination angle within the range. In this case, the inclination angle α of the outer wall portion 33a is different depending on the part so that the incline angle closer to the sirocco fan 18 is larger and the leeward side closer to the outlet 41 is smaller. In other words, the outer wall portion 33a has a curved shape.

  Further, the blower outlet connection portion 33 forms a nose portion 61 that extends so that an inner wall portion 33 b that is a wall portion on the sirocco fan 18 side extends along the sirocco fan 18. And the outer side wall part 33a becomes a structure which begins to incline with respect to the blower outlet 41 from the sirocco fan 18 side rather than the nose part 61, ie, the windward side. According to this configuration, the distal end portion of the nose portion 61 and the portion of the outer wall portion 33a that faces the distal end portion of the nose portion 61 are brought closer to each other. As a result, a reduced portion 71 in which the space through which the wind passes is reduced is formed in the air flow path 51, in this case, at a portion that becomes an exit portion of the sirocco fan accommodating portion 31.

  According to the indoor unit 10 of the air conditioner, when viewed from the front side of the indoor unit body 11, when the indoor unit body 11 is divided into the left region RA and the right region RB with the center line L of the outlet 41 as a boundary, The sirocco fan 18 is entirely within the left region RA. According to this configuration, since the sirocco fan 18 is disposed at a position greatly deviated from the center in the indoor unit body 11, the air outlet 41 is provided near the center of the indoor unit body 11 and on the side opposite to the sirocco fan 18. A sufficient space can be secured. Therefore, a sufficient opening area of the air outlet 41 through which air is blown out can be secured.

  Moreover, according to the indoor unit 10, the electrical component box 21 is provided in the region RB on the opposite side to the region RA in which the entire sirocco fan 18 is accommodated. According to this configuration, among the components constituting the indoor unit 10, the heavy fan motor 19 and the electrical component box 21 can be arranged separately on the left and right in the indoor unit body 11. Therefore, the position of the center of gravity of the indoor unit 10 as a whole can be adjusted to the vicinity of the center of the indoor unit 10, for example, improving workability when installing the indoor unit 10 and stability after installing the indoor unit 10. can do.

  Further, according to the indoor unit 10, the air outlet connection portion 33 is inclined with respect to the air outlet 41 at the outer wall portion 33 a opposite to the sirocco fan 18. According to this configuration, the air direction of the air blown out from the portion on the opposite side of the sirocco fan 18 in the blower outlet 41 spreads outward along the inclination of the outer wall portion 33a. The air can be blown out not only in the opening direction. Therefore, wind can be sent over a wide area in the room, and comfort can be improved.

  Further, according to the indoor unit 10, the air outlet connection portion 33 forms a nose portion 61 that extends so that the inner wall portion 33 b on the sirocco fan 18 side extends along the sirocco fan 18. The outer wall 33a on the opposite side of the sirocco fan 18 starts to tilt with respect to the air outlet 41 from the windward side of the nose 61. According to this configuration, since the reduced portion 71 in which the space through which the wind passes is reduced is formed in the blower path 51, when the speed of the air flowing by the blowing action of the sirocco fan 18 passes through the reduced portion 71. The air blown out from the air outlet 41 can be sent further into the room.

In addition, this embodiment is not limited to one embodiment mentioned above, For example, it can expand or deform | transform as follows.
For example, the indoor unit 10 may have a configuration in which the electric component box 21 is stored in the left region RA and the sirocco fan 18 is stored in the right region RB. Also with this configuration, a sufficient space for providing the air outlet 41 in the vicinity of the center of the indoor unit main body 11 and the portion opposite to the sirocco fan 18 can be secured, and the opening of the air outlet 41 through which air is blown out is provided. A sufficient area can be secured. Moreover, the fan motor 19 and the electric component box 21 which are heavy objects can be disperse | distributed and arrange | positioned in the left and right in the indoor unit main body 11, and the gravity center of the indoor unit 10 can be stabilized.

  Moreover, as illustrated in FIG. 5, the indoor unit 10 may have a configuration in which the outer wall portion 33 a is inclined in a straight line rather than a curved line with respect to the air outlet 41. Even with this configuration, the air direction of the air blown out from the portion of the air outlet 41 on the opposite side to the sirocco fan 18 in particular spreads outward along the inclination of the outer wall portion 33a, so that the air is sent over a wide area in the room. It is possible to improve comfort.

  Moreover, as illustrated in FIG. 6, the indoor unit 10 may be configured such that the outer wall portion 33 a is not inclined with respect to the air outlet 41. According to this configuration, although it is difficult to obtain the effect of sending wind over a wide range in the room, the effect of ensuring a sufficient opening area of the outlet 41 and the effect of stabilizing the center of gravity of the indoor unit 10 are sufficiently exhibited. Therefore, a useful configuration of the indoor unit 10 can be provided.
