Aug. 8. 1967 C. R. WALDROP AUTOMATIC WASHER Filed Sept 20, 1965 United States Patent O 3,334,497 AUTOMATIC WASHER Charles R. Waldrop, Herrin, lll., assignor to Borg- Warner Corporation, Chicago, lll., a corporation of Illinois Filed Sept. 20, 1965, Ser. No. 48S,542 13 Claims. (Cl. 68--23) This invention relates to automatic washers and more particularly to the basket assembly of automatic washers.

Automatic washers frequently employ a clothes-containing basket of the imperforate type and positioned Within a water-collecting tub, and agitation means, such as an Oscillating 'agitator or vertically movable dasher, to eflect movement of the clothes through the water in the basket. The basket conventionally has a generally cylindrical side wall with openings therein extending in a horizontal line adjacent the top of the side wall, or similarly extendng openings provided between the side wall top and a guard ring attached thereto, these openings serving as discharge ports for the water from the basket into the tub during rotating or spinning of the :basket to extract the water from the clothes by centrifugal force. In this water-extraction operation, the wash Water moves up the side wall of the basket and is discharged through the openings into the tub, the side wall of the basket usually having structure, such as a guard ring or inwardly directed rim at the top of the side wall, above the discharge ports to retain the clothes in the basket, during the water-extraction operation. Also, during the rinsing operation, water is supplied to the tub and overfiows through the basket discharge ports Carrying with it scum, -sediment, and detergent.

During the washing period of the described automatic washers, operation of the agitator or dasher Causes the water and clothes to be forcibly moved about in the basket providing considerable turbulence of the water. As a result, water continously surges toward, and is ejected through, the basket discharge ports into the tub thereby decreasing the quantity of water in the basket necessary for insuring proper cleaning of the clothes.

An object of the invention is to provide an improved automatic washer basket assembly having means for retaining water in the basket during a washing operation while providing for the discharge of the water from the basket during a water-extraction operation.

Another object of the invention is to provide an improved automatic washer basket assembly having means, including water flow passages, constructed and arranged to return water, flowing through the passages by agitator action during the washing operation, to the basket, while providing for the discharge of water through the passages and from the basket during the water-extraction operation,

A specific Object of the invention is to provide an improved basket assembly having a guard ring in the basket and having Circumferentially spaced connections to the top of the basket side wall to provide vertically extending passages of water, the guard ring having an inclined upper surface extending r-adially inwardly and downwardly from the exit ends of the passages to ports in the guard ring to return water, forced upwardly through the passages by the agitator action during the washing operation, to the basket.

The drawings are to be understood to be more or less of a schematic character for the purpose of illustrating and disclosing a typical or preferred form of the improvements contemnplated herein and in the drawing like reference characters identify the same parts in the several views.

Referring to the drawing, the basket assembly with which the present invention is particularly concerned is shown, for purposes of 'illustration, incorporated in a washing machine of the type shown and described in U.S. Patent 2,807,951 issued Oct. 1 1957. The washing machine generally comprises a Cabinet A; a basket B of the centrifugal extracting type; an agitator C operatively disposed within the basket B; a transmission D, the housing of which forms a part of and is carried by the basket B for rotation therewith when the basket is rotated for centrifugal water extraction Operations, the transmisison also being adapted to impart an oscillatory motion to a shaft D and thereby to the agitator C; .a reversible electric motor (not shown) connected to the transmi-ssion D; a fluid container or tub E receiving the basket B; and a sequential control M, such as disclosed in U.S. Patent 2,994,749, issued Aug. 1, 1961, and which is adapted to regulate the operation of the various elements in proper Sequence to perform the cycles of Operations involving filling, washing, rinsing and water-extracton.

In FIG. 1, the .Cabinet A which houses the entire mechanism and control system therefor and which comprises atop panel 11, afront panel 12, side panels and a rear panel 14. A control panel 15 forms a part of and projects upwardly from thetop panel 11. Thetop panel 11 is provided with ahinged lid 16 to form a closure member for anopening 17 through which clothes or other articles to be cleansed may be introduced to the machine. The hingedlid 16 is -so disposed with respect to the opening 17 that it will be flnsh with the surface 'of thetop panel 11 when it is in its closed position. One ormore metal straps 18 pivotally disposed in mountings secured to the underside of thecover 11 serve to provide a hinged mounting for thelid 16 with respect to thecover 11.

The control panel 15 has aknob 20 providing means for m anually Operating the sequential control M to provide for the automatic cycles of operation of the machine.

Disposed within the Cabinet A is the water-fight outer tub or container E having acyclindrical side wall 23 terminating in anopen top 24 providing an annular opening, the periphery of which is disposed within the confines of the Cabinettop panel 11 and the peripheral edge of which is provided with an annular shaped Seal 25 adapted to engage portions of the inside surface of the cover in order to prevent water from splashing out of the tub and between the outer surface of the tub and the interior of the Cabinet A.

Disposed within the tub E and arranged for relative rotation therebetween and spaced from thewall 23 of the tub, is the basket B. The basket B comprises a generally cylindricalimperforate side wall 26 andbottom wall 27 having an annular offset at 28 projecting inwardly of the tub and terminating in an annular inwardly projecting flange 29 connected to and adapted to be driven by the transmission D during the Water extraction cycle of the machine.

Integrally formed with the top panel of the Cabinet A and projecting inwardly thereof substantially coaxially with the geometrical aXis of rotation of the: basket B, there is provided anannular flange 30 adapted to present a relatively smooth surface to define a throat through which the fabrics and other materials to be washed may be introduced to the basket B without danger of the fingers of the operator being injured or Caught between the adjacent Operating parts of the washer.

The present invention is directed to the improved watercontrol assembly, generally indicated at F, associated with and forming a portion of the basket. More specifically, the assembly F of the basket B comprises a composite structure formed and arranged to provide a clothes guard effective to prevent clothes ejection from the basket during rotation of the basket at high speed during the waterextraction cycles; ballast for balancing the basket during high speed rotation of the basket; and water control means, cooperative with the guard, ballast and basket side wall, to prevent loss of water from the basket into the tub during the wash-agitate cycles of the machine while providing for the ejection of water from the basket during the water-extraction cycle. In explanation, this composite structure comprises an annular element 3ll having acircular flange 32 defining an opening forming a continuation of theaforementioned throat 30 for the purpose of directing the passage of the clothes, or other material, to be washed into the tub E and basket B. Theflange 32 projects downwardly within the confines of the basket B and terminates in a crcular and generallyhorizontal wall 33 extending radially outward and merging with an integral Vertical wall 34 to form, with theflange 32 andwall 33, an annular pocket for Cement 35 providing ballast for balancing the basket in the high speed rotation thereof during the water-extraction cycles of the washing machine.

The Vertical wall 34 of the assembly F is corrugated with its wavy or undulating formation providing circumferentially spaced radiallyouter portions 36 spot-welded as at 37 to thebasket side wall 26 and also radiallyinner portions 38 with thewebs 39 extending between theseportions 36 and 38 defining, with thewall 26, a series of circumferentially spaced vertically extendingpassages 40. Also, it will be noted that thesewebs 39 form, with the radiallyouter portions 36, a plurality of circumferentially spaced vertically extendingrecesses 39a, closed at their bottoms, filled With ballast Cement 35 for securely anchoring the same.

Referring now to the assembly F and its Water-controlling function, it is important to observe thepassages 40 provide for the flow of water from the clothes and water-containing interior of the basket to anannular chamber 41 formed by thecrcular rim 44 of thebasket wall 26, thewall 32, and thesurface 42 of the ballast 35 forming the bottom of thechamber 30. As seen in FIG. 3, thesurface 40 of the ballast 35 is inclined radially inwardly and downwardly toward a plurality ofopenings 43 in thewall 32, theopenings 43 being in a horizontal plane and being spaced circumferentially about thewall 32 and providing for the discharge of water from theannular Chamber 41 into the basket.

In the operation of the washing machine described, clothes Or other articles to be laundered are inserted into the basket B of the washing machine, and soap or a detergent may be poured onto the clothes in the machine. The timer mechanism M is set in operation to perform the various sequential Operations of the cycle. Initiating the washer operation, the basket B is filled for a predetermined time period with a sufiicient quantity of Water varying with the amount and kind of clothes to be washed, the conventional washing operation requiring that the basket be filled with water to the level indicated in FIGS. 1 and 3 adjacent the top of the basket. Thereafter, a motor (not shown) becomes Operative to cause thetransmission D to oscillate the agitator C to perform its Washing function upon the clothes for a certain period of time.

During the agitator periods of the washer, the transmission D is eflective to cause oscillating rotary movement of the agitator for a predetermined period of time, as Controlled by the timer M. Operation of the agitator Causes the clothes and water to be moved with such force in the basket that the water has considerable turbulence. As a result, water continuously surges and flows upwardly through thepassages 40 into thechamber 41 and down 4, theinclined surface 42 of the ballast 35 through theopenings 43 into the basket, as indicated in FIG. 3. The inwardly turnedrim 44 is effective to contain the Water, flowing upwardly through thepassages 40, in thechamber 41 and also to direct the water inwardly and toward theopenings 43 for returning the water to the basket.

It will be apparent that, by the employment of the basket assembly F, the water in the basket is retained at its proper level so that there is always a suflicient quantity of water in the basket to insure proper cleaning of the clothes during Operation of the agitator in the washing operation of the washing machine.

Upon the conclusion of the allotted time for the washing of the clothes by agitation, the timer mechanism becomes operative to stop the motor and reverse the direction of rotation of the motor to cause the transmission D to rotate the basket B for a water-extracting operation. In this operation, the rotation of the basket B, at high speed, Causes centrifugal forces to move the mass of water outwardly from the geometrical center of rotation and, by virtue of theinclined wall 26 of the basket, the water flows upwardly through thepassages 40 and into theChamber 41 and is then discharged over therim 44 of the basket, as indicated in FIG. 3, into the outer water- Collecting container or tub E for disposal. The pump operates in two directions of rotation so that it rotates in one direction during operation of the agitator and rotates in the opposite direction during the extracting operation. After the water-extraction spin operation, the timer M is eflective to provide a spin rinse of warm water which is effective to remove extraneous scum and detergent remaining in the basket after the first water-extraction spin operation has been completed, the water in the basket is then expelled from the basket as described during the first wash water extraction operation.

Subseqeuntly the motor stops spinning the basket B and the basket is filled with warm rinse water, the agitator then becoming operative during continuous supply of water to the basket to provide an agitated overflow rinse, particularly desirable to clear the clothes in the basket of all scum, sediment and detergent fluid. If the water supply is continuous during this operation, the water fills the basket and overflows throughopenings 45 in thebasket wall 26, communicating withpassages 40, and into the tub E. As seen in FIG. 3, theseopenings 45 are in circumferentially spaced relation in thewall 26 and with anOpening 45 being provided for everyfourth passage 40. It has been determined, in practice, that, during the washing operation involving the agitation periods, a negligible quantity of water flows through theopenings 45 and substantially all of the water flows throughpassages 40 into thechamber 41 and is returned through theopenings 43 into the basket. It will readily :be apparent that the large area and capacity and Vertical direction of thepassages 40 in comparison to the smaller number ofopenings 45 than thepassages 40 and the small area and location of theopenings 45 insures the greater quantity Of water, surging upward through thepassages 40 during agitation, will pass through thepassages 40* into thechamber 41 and only a small inconsequential quantity of water passes through theopenings 45 into the tub. The openings 445 are provided only for the purpose of the overflow rinse period when water enters the basket at such slow rate that, as the Water rises, theopenings 45 permit the water to flow at a comparable rate from the basket into the tub. During rotation of the basket in the waterextraction periods, water is expelled from the basket by substantially all of the water fiowing through thepassages 40 and over therim 44 of the basket, and to insure all Water is evacuated from the basket, including any water returning to the basket throughopenings 43, some of the water is also expelled through theopenings 45 into the tub.

In successive and Concluding Operations, an agitated rinse period without overflow, is provided and the motor is then reversed for the purpose of spinning basket B to extract water from the clothes. The washing operation is concluded by a spin rnse followed by water extraction.
