US Patent 8033145 Drum-type washing machine

While a damper elastically supports, from below, the center of gravity of a water tub, a suspender also elastically supports it, from above, by suspending a front part of the water tub rearward-upward and a rear part thereof frontward-upward. Even when a rated capacity of laundry is put into a drum, although the damper simply elastically supports the center of gravity of the structural load from below, the water tub is prevented from sinking too far, and a door gasket is saved from being damaged from overdeformation.
