Abstract (en)

[origin: EP2781640A1] A drum-type washing machine according to the present invention includes: a rotary drum which is formed in a bottomed cylindrical shape; a water tub which houses the rotary drum; a water circulation system which causes a circulation pump to circulate washing water in the water tub through a circulation path connected to the water tub; a motor which drives the rotary drum; a load detector which detects a load on the circulation pump; and a controller which controls at least one of a washing step and a rinsing step. Further, when the load detector detects a predetermined change in load of the circulation pump while the motor and the circulation pump are being driven, the controller stops driving the motor and stops a function of the circulation pump. Consequently, it is possible to prevent bubbles and air from entering the circulation pump, and prevents excessive bubbling or noise from being caused.
