DRUM TYPE WASHING MACHINE

摘要

PROBLEM TO BE SOLVED: To reduce noise generation by reducing the transmission of the vibration of a water tank when it resonates to an outer casing and a floor face.

SOLUTION: A damper incorporates magnetic viscous fluid and is configured to change a damping force by changing a magnetic field with respect to the magnetic viscous fluid. On the basis of the detection result of the vibration in the resonance by a vibration sensor which detects the vibration of the water tank, the damper reduces the damping force more when the vibration direction of the tank is downward than a case of the upward direction. This constitution can reduce the transmission of the downward vibration of the water tank to the outer casing and to the floor face via the damper so as to reduce the noise generation.
