БАЛАНСИР И СТИРАЛЬНАЯ МАШИНА С ТАКИМ БАЛАНСИРОМ

High amplitude swinging of centrifugal drum prevented - esp. in large capacity domestic washing and drying machines

The swinging due to imbalance of the centrifugal drum of a domestic washing and spinning machine is prevented from reaching high amplitudes by having the drum, in the period before acceleration to centrifugal speed, rigidly supported in its bearings. As the speed of rotation increases, the force of the imbalance is measured and, dependent upon the measurement, the speed of the drum is either lowered to a point below that at which the load of laundry items can rearrange itself, and then increased as from the start, or, is further increased finally to a rate of revolution above the critical figure for the unit, which is then changed over to running in flexible bearings. Eliminates excessive swinging due to imbalance, as well as the need for removing half the load before tumble drying commences. A larger size drum can be fitted without increasing the outside dimensions of the machine, and 4-5 kg of laundry can be washed and dried in a single run.

Horizontal axis washing machine, particularly drum washing machine, has drum, which is rotatably mounted in suspension unit at machine housing, and magnet sensor unit is provided for detecting misalignment of drum
