  • the shutter 5 In the closed state, the shutter 5 is positioned at a second position A2 (see Figure 4 ) where the shutter 5 is in the vertical position or in a position leaning against the stopper 37. Therefore, the shutter 5 can be maintained in the closed state regardless the strength of the wind from the fan 4 or whether air is blown from the fan 4. In addition, it is possible to reduce the load imposed on the stepping motor 6 in the closed state.
  • the shutter 5 can change from the open state to the closed state by rotating to the side far from the fan 4 in the bottom discharge passage P3, specifically, in a direction R2 shown in Figure 4 .

Therefore, when the shutter 5 is in the closed state, the limit switch 36 is actuated and can stop rotational driving of the stepping motor 6. At this time, because the shutter 5 in the closed state maintains the closed state by utilizing pressure of the air flow, there is no danger of air leakage around the periphery of the shutter 5.
  • the shutter 5 of the bottom discharge passage P3 is opened to the first position A1 by a rotational driving force of the stepping motor 6.

  • the heated air can pass through the top discharge passage P2 via the fan 4 and be blown out from the top discharge port 24, and can also pass through the bottom discharge passage P3 via the fan 4 and be blown out from the bottom discharge port 25. Therefore, as the heated air is blown out from the indoor unit 1 to the upper and lower portions of the room, it is possible to quickly heat a room.
  • the shutter 5 is closed to the second position A2 where the shutter 5 is in the vertical position or in a position leaning against the stopper 37 by a rotational driving force of the stepping motor 6.
  • the movable plate 26 of the discharge passage P2 is set to the open state.
  • rotational driving of the stepping motor 6 is stopped by the limit switch 36.
  • the shutter 5 is closed, the shutter 5 is maintained in the closed state by utilizing pressure of the air flow generated by the fan 4.
  • the air flow generated by the fan 4 is cooled by the indoor heat exchanger 3.
  • the cooled air passes through the top discharge passage P2 via the fan 4 and is blown out upward from the top discharge port 24. Thereby the cooled air can cool a room.

  • the bottom short circuit prevention section 51 includes the projected portion 52 disposed at the top of the bottom discharge port 25 and the front edge 53 disposed between the bottom intake port 11b and the bottom discharge port 25. Therefore, in a state in which the space in front of the bottom intake port 11b and the space in front of the bottom discharge port 25 are divided by the front edge 53, the air flow B1 whose direction is changed by the projected portion 52 is blown out forwardly downward from the bottom discharge port 25. Thereby it is possible to reliably prevent short circuit between the bottom intake port 11b and the bottom discharge port 25.
  • the bottom intake port 11b is disposed at a position hidden by the front panel 10 in a front view, and thus the appearance improves.
  • the indoor unit 1 may further include a top short circuit prevention section 65 shown in Figure 6 in order to prevent short circuit at the top.
