Estimating the term…
A room air conditioner includes an air inlet, an air outlet, a heat exchanger disposed between the inlet and outlet, and an air circulation fan. The inlet is opened and closed by motor-driven inlet vanes. The outlet is opened and closed by a vertically slidable motor-driven door. Air direction control vanes extend across the outlet for varying the direction of discharged air. Before the door is either opened or closed, the air control vanes are automatically swung upwardly to a clearance position to avoid interfering with movement of the door. When the inlet and outlet are to be closed, the inlet vane motor is actuated prior the door motor to ensure that the inlet and outlet are fully closed simultaneously, even though it takes longer for the inlet vanes to travel to their fully closed state. A sensor determines when the door reaches an almost-closed state, and the door motor continues to operate for a set period thereafter to ensure that the door becomes fully closed.
A method of operating a room air conditioner which includes a housing forming an air inlet for receiving incoming room air, and an air outlet for discharging the air back into the room, a plurality of vanes extending across the outlet and being mounted for swinging movement to adjust a flow direction of discharged air, a motor-actuated vane drive arrangement for swinging the outlet vanes, a heat exchanger disposed between the air inlet and air outlet for changing the temperature of air passing therethrough, an air circulator for circulating air into the inlet, through the heat exchanger and out through the outlet, an inlet closure for closing the inlet, an outlet closure for closing the outlet, a motor-driven first mechanism for moving the inlet closure between open and closed states, a motor-driven second mechanism for moving the outlet closure between open and closed states, and an input means for inputting operating instructions including operation start and stop instructions, the method comprising the steps of:
A method of operating a room air conditioner which includes a housing forming an air inlet for receiving incoming room air, and an air outlet for discharging the air back into the room, a plurality of outlet vanes extending across the outlet and being mounted for swinging movement to be adjustable for varying a direction of flow of discharged air, a motor-actuated outlet vane drive mechanism for swinging the outlet vanes, a heat exchanger disposed between the air inlet and air outlet for changing the temperature of air passing therethrough, an air circulator for circulating air into the inlet, through the heat exchanger and out through the outlet, an inlet closure in the form of swingable inlet vanes for closing the inlet, an outlet closure for closing the outlet, a motor-driven first mechanism for moving the inlet closure between open and closed states, a motor-driven second mechanism for moving the outlet closure between open and closed states, a detector for sensing a position of the outlet closure, an input means for inputting operating instructions including operation start and stop instructions, and a controller connected to the input means and the first and second mechanisms for controlling operation of the first and second mechanisms, the method comprising the steps of:
