Abstract (en)
[origin: EP1995526A1] In a drain water discharging method for force-feeding drain water via a drain pump, clogging of a drain piping is prevented by controlling the drain pump. An air conditioner has a drain pan for collecting drain water that is dropped from a heat exchanger, a drain pump for discharging the drain water in the drain pan, and a DC motor for driving the drain pump. The DC motor for driving the drain pump is controlled to increase its rotating speed when a rotary torque of the DC motor is increased.
