Abstract

A low frequency vibration type washing machine having at least one horizontally reciprocating disk is disclosed. The disk is provided on the side wall of the washing tub and horizontally vibrates in a direction perpendicular to the direction of gravity of the multi-phase washing medium, thus to generate the resonance phenomena in the washing medium inside the washing tub while saving disk drive energy. The multi-phase washing medium is made of water, detergent and air. The washing machine also includes an actuator which is coupled to the disk for driving this disk. In an embodiment, two disks are provided on the side wall of the washing tub in such a manner that they face each other. In this case, the disks may vibrate so as to form vibrational waves of the same phase or of different phases. The vibrational waves of the disks may have a phase difference larger than -.pi./2 and less than .pi./2.
