High energy efficiency washing system

摘要

A washing machine containing a tub and basket placed within the tub, a basket bottom, a driving shaft coupled to the basket, a motor coupled to the driving shaft, a propeller located within the bottom and impelled by an end of the driving shaft, the propeller containing a scrubber, a center and a support, the scrubbers have a transversal section made from at least three arch circumference sections; a lower face of the propeller has a fin, which along with the bottom, functions as a centrifugal pump creating a current or washing liquor flow which is led through the water tower. In a preferred embodiment, the driving shaft has a solar gear coupled thereto which rotates a satellite gear and over the upper face of the support and between the scrubbers a mini-propeller is provided, the satellite gear is coupled to an axis that rotates the mini-propeller.

主权项

1. In an improved washing machine containing a tub and a basket, which is concentrically placed within said tub, a bottom formed in the basket, a motor coupled to a driving shaft, a propeller located partially within the bottom and impelled by an end of said driving shaft, said propeller containing at least three scrubbers, a center and a support, and a water tower to re-circulate water from the bottom to an upper part of the basket, wherein:
a) the support forms a conic section over which the scrubbers protrude; b) the propeller has an outer diameter greater than fifteen centimeters (5.91 in); c) the at least three scrubbers follow a straight projection over an axis, said axis forming an angle θ with the horizontal, oscillating between five to twenty five degrees, the length of the scrubbers is demarked by the propeller outer diameter and the center base diameter; d) one end of the driving shaft is fitted in the central inferior part of the propeller and the other end of the driving shaft is coupled to a pulley driven by a belt, wherein said belt is driven by a smaller pulley coupled to the motor; e) the lower face of the propeller has at least one fin, which along with the bottom, makes the function of a centrifugal pump to create a current or washing liquor flow; and f) said current or washing liquor flow is led through said water tower.
