Abstract
A low frequency vibration type washing machine has a shrinkable shielder for prevention of clothes jamming in the gap between the low frequency vibrating disc and the inner bottom of the washing tub from the outside. The washing machine includes the washing tub and a vibrating disc placed in the washing tub for causing resonance phenomena in a multi-phase washing medium received in the washing tub. The shrinkable shielder is placed in the gap such that it shields the gap from the outside. The shielder totally or partially shields the gap and is made of rubber or sponge. The shielder may be a tube type shielder placed in the gap at a lower edge of the vibrating disc. Alternatively, the shielder may be a spring type shielder. As a further alternative, the shielder may be a flexible thin film annularly placed in the gap at a lower edge of the vibrating disc. The tube type shielder is charged with gas or liquid.
