<p>PURPOSE:To easily perform the maintenance of an overflow preventive detector by detachably attaching the overflow preventive detector to prevent a drain from overflowing from a drain pan, on an attaching part which faces diagonally forward. CONSTITUTION:For an indoor unit 1, a drain pan 11 is arranged under a heat- exchanger 4. On this drain pan 11, a protruding part which protrudes to the side from the side end part of the heat-exchanger 4 is formed, and a float sensor (overflow preventive detector) 13 is detachably attached on a boss (attaching part) which is provided on the protruding part and faces diagonally forward, by an attaching tool 12. At the time of cooling operation, a drain which adheres on a refrigerant heat-exchanger 4A drops in the drain pan 11, and is discharged to the outside of a room through a drain hose. However, when a trap is formed on the drain hose, and the performing of the discharge of the drain stops, and the drain level has risen, the rise is detected by the float sensor 13, and the operation of an air conditioner is stopped based on the output by a control unit 6.</p> |
