Abstract

An annular cover mounted on top of a clothes washer outer tub and extending inwardly over the clothes basket to contain the splashing of water created by the action of the agitator and to safeguard any overflow onto the base of the cabinet created by a defective water level switch or faulty timer or water valve, the cover having an annular rim engaging the outer tub, and a vertical wall terminating in an inwardly extending downwardly sloping annular flange and having an opening in one side leading into a well externally on the tub and a hose securely fastened to this well externally of the tub whereby in a high water condition the trough and hose will create a siphon thereby maintaining a safe water level before it overflows the cover onto the base, the hose fits through a hole in the base or cabinet of the washer.

mvzmon Peyton W. Douglas PATENTEO SEP] 4 l97l SHEET 2 [IF 2 Peyton W. Douglas WASHING MACHINE TUB COVERS This invention relates to washing machine tub covers and particularly to a tub cover for clothes-washing machines for removing excess suds and water to prevent overflow into the machine.

Clothes-washing machines and particularly automatic clothes-washing machines are provided with an outer housing or cabinet surrounding a stationary water-holding receptacle and an inner rotatable tub and an oscillable agitator axially of both tubs. In automatic forms of such machines the clothes are washed with both tubs stationary and water, is extracted from the clothes by rotating the inner tub at high speed to provide a centrifugal action. This series of operations is controlled by motors, brakes, clutches, switches and electrical contacts usually located beneath the tub.

In the washing operation it is common to provide for series of wash and rinse operations in which water is delivered into the tubs and removed in sequence. It is highly desirable that during these periods, the water in the tubs does not overflow onto the controlling motor, brakes, clutches, switches and the like, cause failure by short-circuiting the electrical system or for some other reason. This can happen, if for some reason, a valve fails to open or close in proper sequence.

The present invention provides a tub cover which confines water and suds within the tubs and in the event of a serious flooding problem carries the water and suds to a discharge point away from the mechanical and electrical equipment of the machine.

Preferably, I provide a unitary molded plastic annular cover having an outer rim tightly engaging the rim of the stationary tub, a generally vertically upstanding annular wall on said rim having an inwardly extending, downwardly sloping flange defining an opening generally corresponding to the opening of the inner tube and discharge means extending over the outer tub and communicating through the upstanding wall, said discharge means having a conduit means extending to the base or cabinet of the washing machine to deliver overflow water to the floor. The discharge means may be an open well or a closed well; in the first case acting as a gravity discharge means and in the second as a siphon means to relive a flooding condition in the washer. Preferably, I also provide a clothes stop extending between the inner and outer tube.

In the foregoing general description I have set out certain objects, purposes and advantages of my invention. Other objects, purposes and advantages will be apparent from a consideration of the following description and the accompanying drawings in which:

FIG. 1 is a section of a clothes-washing machine incorporating my invention.

Fig. 2 is a top isometric view of the machine of FIG. I with the housing top removed.

FIG. 3 is a top isometric view of a second embodiment of cover according to my invention.

Referring to the drawings I have illustrated a clothes-washing machine having an outer housing made up of side panels and top 11. The top 11 is provided with a central access opening 12 and a hinged cover 13. Within the housing is a stationary tub l4 surrounding an inner perforate rotatable tub 15 and agitator 16.

Water is supplied to the machine through a water valve connected to an inlet hose 18 which delivers water to the interior of tub 14. The level of the water in the tub may be controlled by any of the well-known means such as a timer which operates the water valve.

An annular tub cover 20 is provided with an outwardly extending radial rim 21 which having its outer periphery an annular lip 21a which engages the top of tub l4 and is held in place by spring clips 22. A vertical wall 23 extends upwardly from rim 21 spaced from the lip 21a toward the top 11 of the housing and is provided with an opening 24 receiving the inlet hose l8 and with a discharge well 25 which opens through rim 21 and extends beyond rim 21 and is provided with a tubular outlet 26 connected to a depending hose 27 leading to the floor or a floor drain. The vertical wall 23 is provided at its top with an inwardly and downwardly extending flange 28 which defines an access opening 29 whose diameter is substantially that of inner tub opening 30. This flange intercepts water thrown by the agitator and inner tub during their respective operative cycles and directs it back into the tubs.

Preferably a clothes guard 31 extends from rim 21 to a point adjacent inner tub opening 30 to prevent clothes from falling between the inner and outer tubs.

In FIGS. 1 and 2 I have shown the discharge well 25 with a cover 25a which provides a siphon effect in the event a flood condition exists so as to remove water from the tubs.

In FIG. 3, I have shown a second embodiment in which all parts are identical with those of FIGS. 1 and 2 and are identified with like reference numerals carrying a prime sign. However the FIG. 3, the discharge well 25' is not covered and provides for a gravity flow of excess water entering the well.

While I have illustrated and described certain preferred embodiments of my invention in the foregoing specification, it will be understood that this invention may be otherwise embodied within the scope of the following claims.

I claim:
