Abstract

A three-speed-ratio power washing machine includes inner bucket (1), center wave wheel (3) on the bottom, peripheral ring wave wheel (2) of the center wave wheel (3) and planetary reducer clutch (4). The inner bucket (1) is provided with bottom (11). The ring wave wheel (2) and the center wave wheel (3) are both on the bottom (11) of the inner bucket (1). Compared to the existing technology, the utility model adds a ring wave wheel, which rotates with speed different from the inner bucket and the center wave wheel in opposite directions. Friction is not only generated between the inner bucket and the center wave wheel, but also generated between the inner bucket wall and the ring wave wheel. This double friction increases the friction washing effects to the clothes. The water is driven by three different speed ratios of inner bucket, ring wave wheel and center wave wheel, so that a brand new three-speed-ratio power washing machine is created. The water flow strength is increased obviously to form great rolling water flow. The washing and rubbing force is enhanced directly. The washing effects are improved greatly. The utility model is of simple structure and easy to apply.
