Therefore, the moisture absorption duct 68 can easily take in the outside air rising from below through the path r1, and the outside air supplied to the moisture absorption unit 61 is increased, so that the humidification performance is improved.
  • the ribs 56r shown in FIGS. 22 and 23 are partition members that are disposed between the guide structure 56Bb and the front plate 46B and partition the space between the guide structure 56Bb and the front plate 46B.
  • the air flow guided from the air outlet 44 to the air inlet 68a passes through a channel that surrounds the three sides of the front plate 46B, the guide structure 56Bb, and the ribs 56r. Since the air flow is surrounded by the channel formed by providing the ribs 56r (partition members), the air flow that does not reach the intake port 68a by being deviated from this passage is suppressed, so that the air efficiently flows into the intake port 68a. Can be sent in.
  • the partition member is preferably in contact with the front plate 46B to partition the space without a gap, for example, but it is not necessarily required to be in contact with the front plate 46B. There is no.
  • an exhaust duct 80 similar to the humidifying unit 60 shown in FIG. 5 may be provided.

  • the outdoor unit of the present invention can also be configured by an outdoor fan having blades other than the propeller type.
  • a dedicated fan for guiding the outside air to the moisture absorption unit 61 and a motor for driving the fan are omitted.
  • a dedicated fan and a dedicated fan motor which are smaller than the conventional ones are omitted. It may be attached.
  • the outdoor unit can be made more compact than before.
  • the case where the turbo fan 75B and the air supply duct 18 are partitioned by the partition plate 43B has been described. However, as described in the first embodiment or the second embodiment, other places are partitioned. May be. (7-8)
  • the rib 56s is formed only at a portion excluding the overlapping portion 56Bb2 with the air outlet 44 of the guide structure 56Bb.
  • the guide structure may have a baffle member that hinders the flow of air from the intake port toward the blowout port in the vicinity of the end near the rotation center of the outdoor fan.
  • the rib 56t may be formed as a baffle member at the end portion 56Cb3 of the guide structure 56Cb close to. In this case, the flow of air from the intake port 68a toward the outlet 44 can be suppressed by the rib 56t, so that the amount of air guided to the intake port 68a increases compared to the grill 56B.
  • the grill 56C has the same structure as the grill 56B except for the structure of the rib 56s.
  • the baffle member is not limited to the rib structure such as the rib 56t, but may be formed of other members such as a plastic film or a sponge. However, the baffle member has a structure that can be integrally formed with the grill 56B like the rib 56t. preferable.
  • the grill 56C of the third embodiment has a flat inner surface of the guide structure 56Cb.
  • a rectifying member that is disposed between the guide structure and the front plate and extends smoothly from the air outlet toward the air inlet may be provided.
  • the grille 56D shown in FIGS. 25 and 26 is used instead of the grille 56B shown in FIG. 22, and the inner surface of the guide structure 56Db, that is, the guide structure 56Db and the front plate 56B is disposed and blown.
  • a rib 56u that extends smoothly from the outlet 44 toward the intake port 68a may be provided as a rectifying member.
  • the grill 56D has the same structure as the grill 56B except for the structures of the ribs 56s and the ribs 56u.
  • the rectifying member is not limited to the rib structure such as the rib 56u, but a structure that can be integrally formed with the grill 56B like the rib 56u is preferable.
