The valve I I l The present invention relates to washing machines of the type in which clothes are washed and centrifugally dried in a spinner basket and, is particularly concerned with an arrangement f r s pplying liquid to the machine to effect the sitioned to direct the pump discharge through a elimination of the friction drag due to soap suds conduit H to a suitable drain. during centrifugal drying.

The control of edge of the lower section and being telescopgd the correct amount of water is effected by a float within the lower se tion, In th upper part of 2! pivoted on a bracket 22 on the bottom wall of the casing is a spinner basket 6 having outwardly the u er asin d p ng with a P ger flaring side walls provided at the region of great- 23 to shut the valve 14 when the liquid level rises est diameter with centrifugal discharge openings to a small value. For reliable control it is necesl which during washing serve as overflow opensaw that the pump 15 run whenever the valve ings defining the liquid level, Through suitable M is opened to supply wash water initially to fill mechanism, contained in a casing 8, a shaft 8 exthe machine for washing and that the capacity tending up through a sleeve l0 sealed to the of the pump be greate than the flow through the bottom wall of the lower casing section is. sevalve so that the float shuts the valve in response lectively oscillated to oscillate an agitator II for to water overflowing the spinner basket when sufwashing or rotated to rotatethe spinner basket flcient water has been supplied for washing.

3 above the bottom wall of the spinner basket. Under these conditions the friction drag of the soapsuds is suflicient to keep the spinner basket from reaching its centrifugal drying speed and during soapsuds will be dispersed as soon as the basket In the present construction, at the end of the washing period the valve M is opened for a'short interval before and closed a short time after the start of centrifugal drying and the stream discharged from the nozzle is spattered against the side walls and bottom of the basket by striking the flange 20. The spattered stream breaks the soapsuds in contact with the basket and permits the basket to reach its centrifugal drying speed. It will be noted that the fillingnozzle I3 functionsboth to supply water for washing and to eliminate suds lock during centrifugal drying.

The water discharged from the spinner basket during centrifugal drying may be pumped through receiving clothes to be washed and centrifugally dried, a casing surrounding the basket havin storage space below the basket for liquid contents of the basket, an inwardly extending ledge on the casing adjacent the lower end of the basket, and

nomle means for discharging a stream of fresh water downwardly against the ledge, the arrange- 'ment being such as to produce a spray at the lower end of the basket to decrease suds-lock.

2. In a washing machine, a spinner basket for receiving clothes to be washed and centrifugally dried, a casing surrounding the basket having storage space below the basket for liquid contents of the basket, a liquid supply conduit having a nozzle directing a stream of fresh water downwardly along the wall of the casing, and-a de flector adjacent the bottom of the basket positioned in line with said nozzle, the arrangement the conduit I9 to a drain or it may be stored in the bottom of the outer casing and used to fill the spinner basket to wash another load of clothes. When the water is stored inthe bottom of the. outer casing, the float 2| is in a position to shut the valve It so it is not possible to supply an excess of water-to the machine which might cause the water level in the outer casing during centrifugal drying to rise up to the bottom of the spinner basket and place an excessive load on the driving mechanism.

What I claim as new and desire to secure by Letters Patent of the United States is:

I 1. In a washing machine, a, spinner basket for being such that saidstream strikes the deflector and is sprayed inwardly at the lower end. of the basket'to decrease suds-lock.
