Definitions

  • the invention relates to an indoor unit of an air conditioner, and more particularly to an improvement of an airstream direction guide device which is disposed in a discharge port and discharges and guides heat-exchanged air into a room.
  • the indoor unit comprises an airstream direction guide device which discharges and guides obtained heat-exchanged air such as cool air and the like into a room.
  • This type of airstream direction guide device includes a right/left airstream direction louver, which is disposed in a discharge port of an indoor unit main body, an up/down airstream direction louver, and a drive source and a drive mechanism which drive the right/left and up/down airstream direction louvers.
  • right/left airstream direction louvers are disposed in a discharge ventilation path formed downstream of a blower, and an up/down airstream direction louver is disposed in a discharge port as a leading end of the discharge ventilation path.
  • a feature of the invention resides in that the up/down airstream direction louver is divided to a main airstream direction plate and a sub airstream direction plate so that they function in a warming operation.
  • provision of the up/down airstream direction louver in the discharge port of the leading end of the ventilation path permits an airstream direction of the heat-exchanged air discharged from the discharge port to be controlled in a width having a relatively wide angle in an up/down direction.
  • the right/left airstream direction louver is disposed halfway of the discharge ventilation path in the indoor unit main body, the airstream direction of the heat-exchanged air is controlled in a very narrow control width in a right/left direction.
  • Jpn. Pat. Appln. KOKAI Publication No. 2006-300460 discloses an air conditioner configured such that an up/down airstream direction louver (up/down airstream direction plate) is turnably disposed in a discharge port, right/left airstream direction louvers (right/left airstream direction plates) are turnably disposed in the up/down direction louver, and a drive unit, which drives the right/left airstream direction plate, includes a drive motor which is disposed in a side portion of the discharge port and an interconnection unit which interconnects the drive motor with the right/left airstream direction louvers.

Moreover, in this state, the up/down airstream direction louver is formed concave on the lower portion side and formed convex on an upper portion side. Accordingly, most of the cool air guided by the up/down airstream direction louver does not travel in a horizontal direction but travels to a downward floor surface.
  • this type of indoor unit is of a wall-hanging type and attached to a high location in a room, in a cooling operation, it is preferable to guide cool air in a horizontal direction as far as possible so as not to supply the cool air to the feet of an occupant.
