Patent ID: 7849706

Claim:
An indoor unit of an air conditioner, comprising: a casing including a suction port; a panel configured and arranged to open said suction port by moving so that said panel is spaced apart from said casing, and to close said suction port by moving so that said panel is proximate to said casing; a fan motor; a moving mechanism configured to move said panel to open said suction port to a desired degree of opening; a panel drive motor configured and arranged to drive said moving mechanism to move said panel; a control unit configured to execute an air conditioning operation in one operation mode selected from a plurality of operation modes, said control unit controlling said panel drive motor to control said moving mechanism to modify a degree of an opening of said suction port to said desired degree of opening corresponding to said one operation mode selected from said plurality of operation modes by controlling said moving mechanism, said control unit controlling said fan motor to modify air volume output; and a ventilating fan rotationally driven by said fan motor and controlled by said control unit via said fan motor such that when said control unit is instructed to perform a first operation mode among said plurality of operation modes, said control unit sets an output of said ventilating fan via said fan motor to a first air volume and opens said suction port to a first degree of opening by controlling said moving mechanism via said panel drive motor to cause said front panel to transition to a first open state and to stop and to remain in said first open state during said first operation mode, and when said control unit is instructed to perform a second operation mode among said plurality of operation modes, said control unit sets an output of said ventilating fan via said fan motor to a second air volume less than said first air volume, and opens said suction port to a second degree of opening greater than said first degree of opening by controlling said moving mechanism via said panel drive motor to cause said front panel to transition to a second open state greater than said first open state, and to stop and to remain in said second open state during said second operation mode.
