4 Claims. l

This invention relates to a washing machine, and more particularly to a means for introducing water into 'a tub and to other chambers or compartments of, the machine.

In domestic or household washing machines, and particularly washing machines of the automatic type, trouble has been experienced from time to time in scum accumulating over the clothes containing baskets of the machine. Trouble has also been experienced in providing a suitable means for spraying the water over the clothes to obtain what is commonly termed in the trade as a spray rinse.

One of the principal features and objects of the present invention is to provide a novel means for introducing water or other fluid into a washing machine of the type having a stationary tub and a rotatable perforated article-containing basket therein.

A further object of the present invention is to provide a novel uid system including a novel means for introducing water into the tub of an automatic washing machine.

A further object of the present invention is to provide a novel means for cleaning out the float chamber of a washing machine at the same time that water is being introduced into the tub.

A still further object of the present invention .is to provide a novel means for introducing water into a washing machine which includes a rotatable clothes container having an inturned upper,

ange provided with an annular series of holes therein, the water or other uid being directed against this upper ange while the clothes container is being rotated.

A still further difliculty which has been experienced by the trade lies in the fact that a socalled suds lock frequently occurs between the basket and the tub of a washing machine. It has been found that the suds will frequently become so stiff that the basket never reaches full speed and therefore overheats the motor and fails to properly extract the water from the clothes or other articles in the basket.

One of the features and objects of the present invention is to provide novel means for eliminating this suds lock between the basket and the tub.

'I'he novel features which we believe to be characteristic of our invention are set forth with particularity in the appended claims. Our invention itself, however, both as to its organization and manner of construction, together with further objects and advantages thereof, may best be under# stood by reference to the following description 2 taken in connection with the accompanying drawing, in which:

Figure 1 is a diagrammatic plan view of a washing machine embodying the novel teachings ,and principles of the present invention, with the cover and top wall thereof removed; and

Figure 2 is an enlarged fragmentary vertical sectional view of the portion of the washing machine at the point where the water is being introduced into the tub and basket.

The embodiment of the invention illustrad in Figures 1 and 2 of the drawing is employed on a washing machine ID which includes an outer casing or cabinet I I, a stationary tub I 2 and a rotatable clothes or article container I3. This rotatable container I3 may be any of a wide variety of types which enables the centrifugal extraction of water or other fluid from the clothes carried in the container. In the particular form of vthe invention illustrated in the drawing the clothes container I3 is in the form of a perforated basket having a plurality of openings I4 in the side walls thereof; The tcp of the clothes container I3 is provided with an inturned flange I5 which terminates in a beaded edge I6. The flange portion I5 is provided with an annular series of holes I1.

The stationary tub I2 is mounted on a floating base I8 which is carried by a plurality of supporting arms I9 (shown in section only) from the casing II.

The top portion of the side wall of the tube I2 is bent so that in cross section it forms an cutwardly facing channel portion 20. Welded or otherwise suitably secured to this marginal portion 20 is an inturned flange plate 2| which is welded or otherwise suitably secured by a mating flange portion 22 to the top lip 23 of the marginal portion 20 of the tub I 2.` The flange plate 2I is provided at its radially inner edge with a downturned flange portion 24 in which'is disposed a collar part 25. The collar part 251s welded or otherwise suitably secured to the down-turned lip 24. Surrounding the collar part 25 is a weight ring 26 which tends to stabilize vibratory movement of the tub 2li when the clothes container I3 is being rotated. The means for rotating the clothes container I3 forms no part of the present invention and is not illustrated herein.

It is to be understood, however, that when it is desired to extract water from the clothes or other articles within the container I3, the container I3 is rotated at high speed after the water has been withdrawn from the tub I2. Any conventional sort of washing machine agitator may be employed, such as the agitator 21, which is shown in Figure 1 of the drawing. This agitatir forms no part of the present invention, and for the purposes of understanding this invention it is sumcient to state that it is oscillated back and forth about a vertical axis, while the tub is substantially full of water.

In order to introduce a spray rinse into the basket I3 for the clothes or other articles being washed, and also in order to eliminate any suds lock between the basket I3 and the tub I2, water is introduced through a Water supply fitting 28 which is mounted on the flange plate 2l directly over the line of holes I1 in the rotating basket flange I5. The water is supplied to this fitting 28 through a hose 29. The fitting opens directly downwardly so that as the water flows through the fitting 28 it falls on the convexly curved inwardly extending ange portion I5 of the basket I3. Due to the fact that the basket is rotated during the time that the water is introduced, a portion of the Vwater passes through the holes I1 and is atomized or broken up into a fine spray due to the rotation of the basket. This fine spray is designated by the reference character 30 in Figure 2 of the drawing.

Another portion of the stream of Water which is flowing against the rotating basket I3 splashes down over the side as at 3I. Due to the high speed of rotation of the basket I3 this water is thrown around by the basket I3 and thus breaks up any suds lock (accumulation of suds) between the basket I3 and the tub I2. The suds, of course, is carried away at the bottom of the tub through the usual drain.

A third portion of the water striking the top of the ange I5 splashes inwardly over the beaded edge I6 as at 32. 'I'his keeps the entire upper part of the basket free of an accumulation of suds,'calcium deposits and other foreign Inaterial, and also serves to further form a spray rinse for the clothes or other articles in the basket I3.

It has also been found to be desirable to provide a bleeder hose 33 which is connected to the fitting 28 and extends to a position at the top of the float chamber 34. Thus, whenever water is being introduced into the tub I2 for the spray rinse, a small amount of water is also introduced into the oat chamber 34 for the purpose of cleaning the walls of the float chamber and the oat itself. This prevents an accumulation of calcium deposits and other foreign material within the iioat chamber.

While we have shown a particular embodiment of our invention, and described a particular method of operation, it will, of course, be understood that we do not wish to be limited thereto, since many modifications may be made, and we, therefore, contemplate by the appended claims, to cover all such modifications as fall within the true spirit and scope of our invention.
