Definitions

  • the present disclosure relates to an indoor unit of an air conditioner.
  • the airflow direction adjusting flap (85) is curved downward along the air flow, the air blown out of the blow-out passage (73) is easily directed downward. However, the air is hardly blown upward.
  • the airflow direction adjusting flap (85) that is directing the air upward relative to the horizontal plane has the flat upper surface. Thus, this airflow direction adjusting flap (85) easily directs the air blown out of the blow-out passage (73) either downward or upward. Specifically, if the airflow direction adjusting flap (85) is directed downward, the air flowing through the blow-out passage (73) from the first lower end (76) to the second lower end (77) can be blown downward.
  • an angle range in which the airflow direction adjusting flap (85) is capable of directing the air upward relative to the horizontal plane is greater than 0° and less than or equal to 10°, where the horizontal plane has an angle of 0°.
  • the casing (33) includes: a first casing (51) in which the heat exchanger (31) and the fan (32) are disposed; and a second casing (71) having the blow-out passage (73) and the air outlet (75), and fitted to the first casing (51).
  • the first back panel (56) of this body unit (50) has the air inlet (60), and the first front panel (55) opposed to the first back panel (56) has an air outflow port (59).
  • the body unit (50) has therein an air passage (61) extending from the air inlet (60) to the air outflow port (59).
  • the air passage (61) in the body unit (50) houses the indoor heat exchanger (31), the indoor fan (32), and the drain pan (35).
  • the indoor heat exchanger (31) is disposed in a portion of the air passage (61) located on the leeward side of the indoor fan (32) and between the air inlet (60) and the air outflow port (59).
  • the air conditioner (10) selectively performs cooling operation and heating operation.
  • the airflow direction adjusting flap (85) is simply provided at the air outlet (75) without the provision of a passage through which air is straightened. In that case, even if the angle of the air blown is set at an upward angle, the air that has passed through the indoor air (31) tends to be diffused. Thus, the air blown out of the indoor air (31) hardly reaches a region far away from the indoor unit. This makes it difficult for conditioned air to circulate through the room.
  • the blow-out passage (73) is disposed downstream of the outer peripheral portion (37) of the drain pan (35) in the airflow direction. According to this configuration, the air that has passed through the heat exchanger (31) passes through the outer peripheral portion (37) of the drain pan (35), and then flows into the blow-out passage (73). This facilitates straightening the air on the downstream side of the heat exchanger (31) through the blow-out passage (73).
  • the second lower end (77) is located below the first lower end (76), and the height of the second lower end (77) of the bottom surface (78) of the blow-out passage (73) is greater than that of the lowermost end of the downstream bottom portion (78a).
  • This relationship in height allows air flowing along the bottom surface (78) of the blow-out passage (73) to flow downward through the blow-out passage (73), and then allows the flow of the air to be turned upward by the blow-out surface (84b) upon passing of the air through the lowermost end.
  • the air is blown out of the blow-out passage (73).
  • the airflow direction is changed smoothly due to the entire bottom surface configured as the curved surface.
  • the second lower end (77) may be at the same height as the lowermost end of the downstream bottom portion (78a).
  • the blow-out surface (84a) forms a horizontal surface as in the first embodiment.
  • Such a configuration also exhibits advantages substantially similar to those of the first variation that is not according to the present invention shown in FIG. 10 .
  • the indoor unit (30) including the additional unit (100) can blow conditioned air straightened in the blow-out passage (73) upward, as in the first embodiment. This makes it easy for the conditioned air to reach a region far away from the indoor unit (30), as in the first embodiment. This allows the conditioned air to easily circulate through the room.
