Abstract:
1. In an improved washing machine having a tub and a basket, which is concentrically disposed within the tub, a bottom formed in the basket, a motor coupled to a driving shaft, a propeller having a center and a support and located partially within the bottom and propelled by the driving shaft, and a water tower to circulate water from the bottom to an upper part of the basket, the improvement comprising: at least three scrubbers disposed on the propeller, each respective scrubber defining a respective transversal section comprising a first curve joined to an slope arch, which in turn is joined to an apex arch, the first curve corresponding to a foot of the respective scrubber, wherein the first curve obeys a circumferential arch equation whose radius ranges from half a centimeter to three centimeters, wherein a foot arch is defined by an angle alpha ranging from five degrees to twenty degrees and a radius ranging from two centimeters to five centimeters; the slope arch following a curve described by a circumferential arch having a radius ranging from seven centimeters to fifteen centimeters, wherein the slope arch is defined by an angle beta ranging from fifteen degrees to thirty degrees and a radius ranging from ten centimeter to twenty centimeters; and the apex arch configured to join slope arches respectively located on each side of a symmetry axis following a circumferential arch whose radius ranges from eight millimeters to fifteen millimeters, wherein the apex arch is defined by an angle phi ranging from forty degrees to ninety degrees and a radius ranging from three millimeters to ten millimeters, wherein one end of the driving shaft is coupled to a central inferior part of the propeller and the other end of the driving shaft is coupled to a pulley driven by a belt, wherein the belt is driven by the motor, wherein the propeller support comprises a transverse section formed by a circumferential arch, wherein a propeller body comprising the support has a conic configuration, wherein a lower face of the propeller has at least one fin, which together with the bottom operates as a centrifugal pump to create a current or washing liquor flow, and wherein the current or washing liquor flow flows through the water tower.
