  • the first vane 4a1 and the second vane 4a2 form a single imaginary vane having an imaginary chord larger than a chord of each of the first vane 4a1 and the second vane 4a2.
  • the first vane 4a1 and the second vane 4a2 function as two separate vanes each having an individual chord. That is, it can be said that it is possible to obtain a mode in which vane chords are varied in accordance with airflow directions without exchanging the vanes themselves.

  • the first embodiment in spite of using three vanes, it is possible to provide a design enabling only two vanes to be recognized as the openable/closable portions during shutdown. Further, there are quite a few fears in that dust and the like intrude into the main body from an outer edge of the openable/closable portion during shutdown. However, in the first embodiment, in spite of using three vanes, the number of vanes recognized as the openable/closable portions during shutdown is reduced to two, thereby being capable of expecting prevention of undesirable intrusion of dust and the like into the main body.

Accordingly, dew condensation can be prevented, and quality can be enhanced.
  • the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that, when the first vane 4a1 and the second vane 4a2 are aligned in series, the upper surface (surface on the main body side) of the first vane 4a1 has the upward convex shape (shape convex toward the main body) and the lower surface (surface on the side opposite to the main body) of the second vane 4a2 has the downward convex shape (shape convex toward the side opposite to the main body) .
  • the second vane 4a2 is aligned in parallel to the first vane 4a1.
  • the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that the surface of the second vane 4a2 opposed to the first vane 4a1 has the convex shape swelling toward the first vane 4a1, and that the surface of the first vane 4a1 opposed to the second vane 4a2 has the convex shape swelling toward the second vane 4a2. Accordingly, during heating, the airflow flowing between the first vane 4a1 and the second vane 4a2 flows through a region surrounded by the convex shape of the first vane 4a1 and the convex shape of the second vane 4a2.
  • the airflow is gradually narrowed so that a separation vortex is prevented. Then, the airflow is gradually enlarged, with the result that disturbance of the airflow is prevented. Therefore, generally speaking, straight flowability of the airflow is increased, and a floor reachable distance of the airflow is extended, thereby increasing an effect of being capable of heating a region around feet of a user.

  • the stabilizer 9 is configured to partition the inlet-side air duct E1 and the outlet-side air duct E2, and as illustrated in FIG. 15 , the stabilizer 9 is mounted on the upper side of the heat exchanger 7.
  • the inlet-side air duct E1 is positioned on the lower side of the stabilizer 9, and the outlet-side air duct E2 is positioned on the upper side of the stabilizer 9.
  • the stabilizer 9 includes the tongue portion 9a configured to separate the inlet-side air duct E1 and the outlet-side air duct E2 from each other, and the diffuser 3a1 being a lower wall surface (front-surface-side wall surface) of the outlet air duct 3a of the air outlet 3. Further, the drain pan 409b configured to temporarily accumulate water droplets dripping from the heat exchanger 7 is arranged on the lower side of the heat exchanger 7.
  • the vertical airflow-direction vane 4a is arranged in the outlet air duct 3a.
  • the vertical airflow-direction vane 4a includes the first vane 4a1, the second vane 4a2, and the third vane 4a5.
  • the first vane 4a1, the second vane 4a2, and the third vane 4a5 have the separate driving sources, respectively, and are pivoted individually.
  • the first vane 4a1 closes a part of the air outlet 3 in the front portion of the upper surface 1b, and forms the outer surface of the apparatus body. That is, the first vane 4a1 serves as both the airflow-direction control portion and the designed portion for the contour of the main body.
  • a lower surface (surface on the air duct side) of the first vane 4a1 during shutdown has a convex shape.
  • the first vane 4a1 is arranged in a pivotable manner, and the pivot axis of the first vane 4a1 is positioned close to the guide wall in an upper portion of the outlet air duct 3a.
  • the third vane 4a5 closes a part of the air outlet 3 in the upper portion of the front surface 1a, and forms the outer surface of the apparatus body. That is, the third vane 4a3 also serves as both the airflow-direction control portion and the designed portion for the contour of the main body.
  • the second vane 4a2 is accommodated in the outlet air duct 3a, and is arranged between the first vane 4a1 and the cross-flow fan 8 and between the third vane 4a5 and the cross-flow fan 8. More specifically, during shutdown, the entire second vane 4a2 is accommodated in the main body 1. Meanwhile, during operation, the second vane 4a2 projects outward from the air outlet 3. That is, the second vane 4a2 functions as the airflow-direction control portion, but does not function as the designed portion for the contour of the main body.
  • the second vane 4a2 is directly aligned with the first vane 4a1 during horizontal blowing (frontward blowing) as illustrated in FIG. 17
  • the second vane 4a2 is aligned in parallel to the first vane 4a1 during upward blowing (vertical blowing) as illustrated in FIG. 16
  • the first vane 4a1 and the second vane 4a2 are aligned in a fore-and-aft direction during downward blowing (vertical blowing).
  • the third vane 4a5 is at the same position and in the same posture as those during shutdown.
  • the third vane 4a5 is in the same posture as that during upward blowing, and rises from the position during upward blowing, thereby guiding air toward the lower surface of the second vane 4a2 in cooperation with the stabilizer 9.
  • the third vane 4a5 opens a part of the air outlet 3 above the front surface 1a.
  • the third vane 4a5 is inclined so that a front portion of the third vane 4a5 is positioned below a rear portion of the third vane 4a5. With this configuration, the third vane 4a5 guides downward the air passing through the part of the outlet 3 above the front surface 1a.
  • the pivot axis of the second vane 4a2 is positioned in a lower portion of the air outlet 3 and close to the stabilizer.
  • the second vane 4a2 is moved to the front side of the first vane 4a1 in the forward direction of the blown-out air, and then is aligned with the first vane 4a1 in series. It is necessary to arrange the first vane 4a1 and the second vane 4a2 in series under a state in which, in side view of FIG.
  • the upstream end C of the second vane 4a2 is positioned above the imaginary line V connecting the upstream end A of the first vane 4a1 and the downstream end B of the second vane 4a2 to each other (state in which the upstream end C is positioned on the side away from the main body 1 with respect to the imaginary line V).
  • the first vane 4a1 and the second vane 4a2 form the single imaginary vane having the imaginary chord larger than the chord of each of the first vane 4a1 and the second vane 4a2.
  • the first vane 4a1 and the second vane 4a2 function as the two separate vanes each having the individual chord. That is, it can be said that it is possible to obtain the mode in which the vane chords are varied in accordance with the airflow directions without exchanging the vanes themselves.
  • the clearance 20 is secured between the first vane 4a1 and the second vane 4a2 arranged in series.
  • the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that, when the first vane 4a1 and the second vane 4a2 are aligned in series, the lower surface (surface on the main body side) of the first vane 4a1 has a downward convex shape (shape convex toward the main body) and an upper surface (surface on the side opposite to the main body) of the second vane 4a2 has an upward convex shape (shape convex toward the side opposite to the main body).
  • the second vane 4a2 is moved to a position between the first vane 4a1 and the third vane 4a5, and is shifted to a posture substantially parallel to the first vane 4a1 and the third vane 4a5. That is, during upward blowing, the second vane 4a2 is aligned in parallel to the first vane 4a1. Further, at this time, the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that the surface of the second vane 4a2 opposed to the first vane 4a1 has the convex shape swelling toward the first vane 4a1 and the surface of the first vane 4a1 opposed to the second vane 4a2 has the convex shape swelling toward the second vane 4a2.
  • the air conditioner having the above-mentioned configuration can obtain the following effects similarly to the first embodiment.
  • the second vane 4a2 is accommodated in the outlet air duct 3a during shutdown, whereas the second vane 4a2 projects outward from the air outlet 3 during operation.
  • the second vane 4a2 can have a shape suitable for controlling airflow directions without being restricted by design conditions required for the outer surface of the body, and at least one airflow-direction control vane having a shape suitable for controlling airflow directions is reliably secured.
  • the outer surface of the main body include a smaller portion that can be recognized the openable/closable portion during shutdown.
  • the design in spite of using three vanes, it is possible to provide the design enabling only two vanes to be recognized as the openable/closable portions during shutdown. Further, there are quite a few fears in that dust and the like intrude into the main body from the outer edge of the openable/closable portion during shutdown. However, in the first embodiment, in spite of using three vanes, the number of vanes recognized as the openable/closable portions during shutdown is reduced to two, thereby being capable of expecting prevention of undesirable intrusion of dust and the like into the main body.
  • the second vane 4a2 is aligned with the first vane 4a1 in series. Accordingly, during horizontal blowing, the first vane 4a1 and the second vane 4a2 form the single imaginary vane having the imaginary chord larger than the chord of each of the first vane 4a1 and the second vane 4a2.
  • the first vane 4a1 and the second vane 4a2 function as the two separate vanes each having the individual chord. That is, it can be said that it is possible to obtain the mode in which the vane chords are varied in accordance with the airflow directions without exchanging the vanes themselves.
  • the imaginary vane having the imaginary chord larger than the chord of the individual vane As described above, it is possible to obtain the imaginary vane having the imaginary chord larger than the chord of the individual vane.
  • the clearance 20 is secured between the first vane 4a1 and the second vane 4a2 arranged in series.
  • the first vane 4a1 and the second vane 4a2 are arranged in series under the state in which the clearance 20 is secured.
  • the air during cooling flows over both upper and lower surfaces of the second vane 4a2 beyond the clearance 20 between the first vane 4a1 and the second vane 4a2, thereby reducing the temperature difference between both the upper and lower surfaces of the second vane 4a2. Accordingly, dew condensation can be prevented, and quality can be enhanced.
  • the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that, when the first vane 4a1 and the second vane 4a2 are aligned in series, the lower surface (surface on the main body side) of the first vane 4a1 has the downward convex shape (shape convex toward the main body) and the upper surface (surface on the side opposite to the main body) of the second vane 4a2 has the upward convex shape (shape convex toward the side opposite to the main body).
  • the second vane 4a2 is aligned in parallel to the first vane 4a1.
  • the first vane 4a1 and the second vane 4a2 are moved in a pivoting manner so that the surface of the second vane 4a2 opposed to the first vane 4a1 has the convex shape swelling toward the first vane 4a1, and that the surface of the first vane 4a1 opposed to the second vane 4a2 has the convex shape swelling toward the second vane 4a2. Accordingly, the airflow flowing between the first vane 4a1 and the second vane 4a2 flows through the region surrounded by the convex shape of the first vane 4a1 and the convex shape of the second vane 4a2.
  • the airflow is gradually narrowed so that the separation vortex is prevented. Then, the airflow is gradually enlarged, with the result that the disturbance of the airflow is prevented. Therefore, generally speaking, the straight flowability of the airflow is increased, and the reachable distance of the airflow is extended, thereby obtaining an advantage in that an effect of air conditioning is easily spread in the entire room.
  • the air outlet is open only toward the upper surface of the main body, but is not open toward the front surface thereof. Accordingly, noises generated by functional components arranged inside the main body (such as a noise generated when driving the motor of the cross-flow fan, the wind noise of the cross-flow fan, and the noise generated when refrigerant in the heat exchanger flows) are prevented from directly leaking frontward. As a result, there are achieved both noise prevention, and increase in airflow-direction controllability exerted by a vane that is not restricted by the design conditions. Further, as described above, the second vane projects outward from the main body, and is aligned with the first vane in series.
