Definitions

  • each blow-out port becomes shorter in length along the pivot axis of the corresponding blow-out port, which may cause degradation in performance, specifically reduction in amount of air to be blown out through each blow-out port.
  • the present invention provides an indoor unit for an air conditioner, the indoor unit being capable of reduction in size and improvement in performance.
  • the driver is disposed in the casing so that the driver and the flap are arranged in the direction perpendicular to the pivot axis of the flap. Therefore, the driver does not adjoin the blow-out port along the pivot axis of the flap. An increased amount of air is thus blown out through the blow-out port in such a manner that a length of the blow-out port along the pivot axis of the flap is made longer even when a length of the casing along the pivot axis of the flap is made shorter.
  • the indoor unit for an air conditioner is thus capable of reduction in size and improvement in performance.
  • the length of the blow-out port along the pivot axis of the flap is at least 85% of the length of the casing main body along the pivot axis of the flap. This configuration therefore ensures increase in amount of air to be blown out through the blow-out port.
  • the flap includes:
  • the present invention provides an indoor unit for an air conditioner, the indoor unit being capable of reduction in size and improvement in performance.
  • FIG. 1 is a perspective view of an indoor unit for an air conditioner according to an embodiment of the present invention, the indoor unit being seen obliquely from below.
  • FIG. 2 is a perspective view of the indoor unit seen obliquely from above.
  • the indoor unit is designed to be embedded in a ceiling, and includes a casing main body 1, a panel 2 having a quadrilateral shape, the panel 2 being mounted to a lower side of the casing main body 1, and a grille 3 detachably mounted to the panel 2.
  • the casing main body 1, the panel 2, and the grille 3 constitute an example of a casing.
  • the indoor unit also includes a pipe connection part 5, a pipe connection part 6, and a drain socket 7 each protruding from a sidewall of the casing main body 1.
  • each of the pipe connection parts 5 and 6 is connected to an external refrigerant pipe (not illustrated).
  • the drain socket 7 is connected to an external drain hose (not illustrated).
  • the panel 2 has a blow-out port 10.
  • the blow-out port 10 is located on one of longitudinally opposite sides of the grille 3 so as to extend along a shorter side of an outer edge of the panel 2.
  • the panel 2 also has a flap 20 pivotably mounted thereto and configured to open and close the blow-out port 10. In FIG. 1 , the flap 20 closes the blow-out port 10.
  • the indoor unit according to this embodiment also includes hanger fittings 101, 102, 103, and 104 (the hanger fitting 104 is illustrated in FIG. 5 ).
  • the hanger fittings 101, 102, 103, and 104 are secured to hanger bolts (not illustrated) suspended from, for example, a framework in a roof-space. The indoor unit is thus suspended from a ceiling.

  • the length L1 of the flap 20 is 280 mm when the length L2 of the casing main body 1 is 315 mm.
  • the flap 20 has a barycenter 22 set at the flap main body 20a so as to define a clearance between the flap main body 20a and the pivot axis 21.
  • the flap 20 is disposed such that the barycenter 22 of the flap 20 is closer to a blow-out port 10 side of the casing main body 1 than the pivot axis 21 is.
  • the stepping motor 80 is disposed in a space defined by the casing main body 1, the panel 2, and the grille 3.
  • the stepping motor 80 and the flap 20 are arranged adjacent to each other in a direction perpendicular to the pivot axis of the flap 20.
  • the stepping motor 80 is located on a side opposite from the blow-out port 10 with respect of the pivot axis 21 in the casing main body 1.

  • the flap 20 receives the driving force from the stepping motor 80 through the link mechanism 90 to turn about the pivot axis 21.
  • the link mechanism 90 transmits the driving force from the stepping motor 80 to the flap 20 so that the flap 20 turns.
