Wash system by recirculating pumping with self balanced centrifugal squeeze dry of laundry

A self balanced spin dry recycle pump laundry wash system, of the type comprising a water centrifugal drying system to eliminate the water that wets the just washed laundry and eliminates the water by introducing the laundry within an inner rotatory drum having holes at its wall side, comprising:

• an inner rotatory drum, that floats while it is rotating over a certain amount of water housed at a controlled level within a second closed external drum;
• the first, inner drum lacks holes in its base or lower part;
• the bottom of this drum is flat, and has a side that broadens upwardly in a conical or round form;
• the upper part or body of the drum is provided with holes and is of a cylindrical form, with a conical or cylindrical broadening in a zone joined to the base, in such a way to form a detent bend for laundry sliding upwarldy;
• an overweight located at the lower part of the inner drum, placed in a way that the gravity center in relation with the flotation center keeps a stable balance and a flotation level suitable during the centrifugation operation;
• the inner rotatory drum is provided at the bottom thereof, with a counterweight which is self adjustable to the displacement of the mass center;
• the external drum has on its wall side, at the same level that the predetermined water level used for the flotation of the inner drum, one or more discharge exits or overflow mouths, connected to a closed container in which the excess water is poured by gravity;
• the container in turn, is connected directly to a discharge pump suction;
• the bottom of the external drum is also connected to the suction of the pump by means of tubing with a control valve;
• in the zone in which the water for flotation of the inner drum is housed, the external drum is provided with means to impede the rotation of the water, said means serving as a detent to the perimetral increase of the water level when it spins due to the impulse of the drum when rotating;
• in the space defined between the wall sides of the two drums, there are located a series of small bearings, mounted in vertical axis and distributed evenly, which have as a function that of avoiding friction between both drums, since they keep a certain side slack, in such a way that the rotation of the inner drum over its shifted mass center is not impeded and at the same time the irregular swing movements of the drum when spinning is limited;
• in the bottom of the external drum, are mounted a series of self aligning bearings or balls with detents, circumferentially distributed in such a manner that the inner drum can rest over them and rotate with respect to its variable mass center.
