EY JAMES SHAO-MIN6 HWAN6, AND PAUL YUN6-TAO HWAN6, BOTH CANADIAN CITIZENS,
BOTH RESIDE AT POSTAL ADDRESS OF No.6 BARROWCLIFF DRIVE, SC~RBOROU6H,

BAC~GROUND OF THE INVENTION
MOST CLEANIN6 DEVICES ~OR COMMERCIALLY CALLED LAUNDRY WASHERS) ON THE
MAR~ET USE DIFFERENT AGITATOR DESIGNS TO CREQTE TURBULENT WATER COMMOTION
TO CLEAN F~BRICS. HOWEVER, FABRIC IS ALW~YS FORCED TO MOVE IN THE SAME
DIRECTION ~S W~TER MOTION, THUS W~TER P~SSES RELATIVELY SLOWLY THROU6H THE
FABRIC AND DIRT P~RTICLES C~NNOT BE EFFICIENTLY WASHED OUT. ONE
hLTERNATIVE IS TO USE MORE CHEMIC~L DETER6ENTS. THIS CAUSES EVEN SEVERE
WATER POLLUTION PRO~LEMS. THE A6IT~TOR MODE ALSO REQUIRES CONSIDERABLE
WATER AND POWER IN ITS OPERATION. THE SOLUTION TO THESE PROBLEMS IS
CONTINUALLY SOUGHT FOR.
SUMMARY OF THE INVENTION
THIS INVENTION RELIES MORE ON PHYSICAL ~CTION THAN CHEMIC~L TO
EFFICIENTLY CLEAN FABRICS. ITS EMBODIMENT COMPRISIN6 A CYLINDRIC~L
CONTAINER, BEINE THE INNER TUB IN CONVENTIONAL WASHIN6 M~CHINES,
7D CONT~ININ6 LAUNDRY FABRICS ~ND WATER, A SH~FT LOCATED AT THE CENTER OFSAID CONTAINER, A NARROW-SHAPE FLAT BODY SECURED TO SAID SHAFT AT THE
CENTROID OF SAID BODY, A COMMON MECHANISM SITU~TED BENEATH S~ID CONT~INER
HAVIN6 ME~NS TO VERTICALLY RECIPROCATE AND SIMULTANEOUSLY CONTINUOUSLY
ROTATE S~ID SHAFT AND BODY. THE NARROW-SHAPE FL~T BODY, DURIN6 ON ITS
DDWN-STRO~E MOTION, PRESSES THAT PART OF FABRICS UHDER IT ro SQUEEZE DIRT
OUT ALON6 WITH WATER ~ND SIMULT~NEOUSLY LOOSENS ~DJ~CENT FABRICS FOR THE
NEXT PRESSIN6 CYCLE WHEN THE BODY HAS ROTATED. THE CONTINUOUS ROTATION OF
THE BODY SUCCESSIVELY COOPERATES WITH THIS OPERATION OVER ~LL THE FABRICS
IN THE CONT~INER.

BRIEF DESCRIPTION OF THE DRAWINGS
THIS INVENTION, AS EXEMPLIFIED BY THE EMBODIMENTS, IS DESCRIBED WITH
REFERENCE TO THE DRAWINGS IN WHICH:
FIGURE 1 IS A PARTLY EXPOSED PERSPECTIVE VIEW OF THE EMBODIMENT OF THE
DEVICE, AND
FIGURE 2 IS A TOP PLAN VIEW OF FIG.l, AND
FIGURE ~ IS A CROSS-SECTIONAL VIEW TAKEN ALONG LINE 5-5 OF FIG.2 IN THE
DIRECTION OF THE ARROWS, AND
FIGURE 4 IS A CROSS-SECTIONAL VIEW TAKEN ALONG LINE 6-6 OF FIG.~ IN THE
DIRECTION QF THE ARROWS.
DETAILED DE5CRIPTION
FIGURES 1,~,3 AND 4 SHOW THE EMBODIMENT OF THIS INVENTION COMPRISING A
CYLINDRICAL CONThINER 7, BEING THE INNER TUE COMMONLY SUPPORTED BY THE
STRUCTURE IN CONVENTIONAL WASHIN5 MACHINES, FOR CONTAINING LAUNDRY FABRICS
AND WATER, A SHAFT 8 LOCATED AT THE CENTER OF CONTAINER 7, A NARROW-SHAPE
FLAT BODY q, HAVING TWO CURVED OPPOSITE 5HORTER EDGES WHOSE RADIUS BEING
SLIGHTLY SMALLER TH~N THAT OF CONTAINER 7 AND THE WIDTH OF SAID BODY, AS
ALONG LINE 6-6, BEING ONE THIRD OF THE DIAMETER OF CONTAINER 7 , SECURED
TO SHAFT 8 AT THE CENTROID OF BODY q, A CaMMON MECH~NISM SITUhTED EENEATH
~O CONTAINER 7 HAVING MEANS TO VERTICALLY RECIPROCATE AND SIMULTANEOUSLYCONTINUOUSLY ROTATE SHAFT 8 AND BODY q. DURING BODY q ON ITS DOWN-STRO~E
MOTION ~S INDICATED BY ARROW 10, IT PRESSES WATER AND DIRT OUT OF THAT
PART OF FABPICS UNDER IT AND SIMULT~NEOUSLY PUSHES WATER TO LOOSEN
ADJACENT FABRICS, AS INDICATED BY ARROWS 11 AND 12, FOR THE NEXT PRESSING
CYCLE WHEN THE BODY HAS ROTATED. THE CONTINUOUS ROTATION OF SHAFT 8 QLONG
WITH BODY q, AS INDICATED BY ARROWS 1~ AND 14, SUCCESSIVELY COOPERATES
WITH THIS OPERATION OVER ALL FABRICS IN CONTAINER 7. THE PRESSING-~ND-
LOOSENING CYCLE OF THIS OPERATION MORE EFFICIENTLY CLEANS FABRICS, USESLESS WATER, DETERGENT AND POWER, AND IS THE FEATURE OF THIS INVENTION.
