Abstract

An automatic washing machine includes a wash tub and a dispenser compartment which is connected to the wash tub. The washing machine further includes a valve assembly having a housing and a rotatable valve member, the housing having (1) a water inlet port defined therein which is connected to a main water line, and (2) a first water outlet port defined therein which is connected to the dispenser compartment, the rotatable valve member (1) disabling a flow of water from the water inlet port to the first water outlet port when the rotatable valve member is positioned at a first valve position, and (2) enabling the flow of water from the water inlet port to the first water outlet port when the rotatable valve member is positioned at a second valve position. Moreover, the washing machine includes a timer mechanism having a rotatable shaft which is positionable at a first shaft position and a second shaft position, the rotatable valve member being positioned at the first valve position when the rotatable shaft is positioned at the first shaft position, and further the rotatable valve member being positioned at the second valve position when the rotatable shaft is positioned at the second shaft position.

Claims

1. An apparatus for diverting a flow of water in a washing machine having a first dispenser compartment, comprising:

a valve assembly including a housing and a rotatable valve member, said housing having (1) a water inlet port defined therein which is connected to a main water line, and (2) a first water outlet port defined therein which is connected to said first dispenser compartment, said rotatable valve member (1) disabling a flow of water from said water inlet port to said first water outlet port when said rotatable valve member is positioned at a first valve position, and (2) enabling said flow of water from said water inlet port to said first water outlet port when said rotatable valve member is positioned at a second valve position; and

a timer mechanism having a rotatable shaft which is positionable at a first shaft position and a second shaft position, said rotatable valve member being positioned at said first valve position when said rotatable shaft is positioned at said first shaft position, and further said rotatable valve member being positioned at said second valve position when said rotatable shaft is positioned at said second shaft position.

2. The apparatus of claim 1, wherein:

said washing machine has a second dispenser compartment,

said housing has a second water outlet port defined therein which is connected to said second dispenser compartment, and

said rotatable valve member enables said flow of water from said water inlet port to said first and second water outlet ports when said rotatable valve member is positioned at said second valve position.

3. The apparatus of claim 1, wherein said rotatable shaft is secured to said rotatable valve member.

4. The apparatus of claim 1, wherein:

said washing machine further has a wash tub, and

said first dispenser compartment is connected to said wash tub.

5. The apparatus of claim 1, wherein:

said timer mechanism includes a first cam having a first cam profile, and

said rotatable shaft is controlled by said first cam profile to assume said first shaft position.

6. The apparatus of claim 5, wherein:

said timer mechanism includes a second cam having a second cam profile, and

said rotatable shaft is controlled by said second cam profile to assume said second shaft position.

7. The apparatus of claim 1, wherein:

said valve assembly further includes a cylindrical mounting member and a seal,

said cylindrical mounting member is positioned within said housing,

said seal is interposed between said cylindrical mounting member and said housing, and

said rotatable valve member includes a rotor which is positioned within said cylindrical mounting member.

8. The apparatus of claim 7, wherein:

said cylindrical mounting member has a number of first apertures defined therein,

said seal has a number of second apertures defined therein which align with said first apertures when said seal is interposed between said cylindrical mounting member and said housing, and

said rotor has a third aperture defined therein, wherein said third aperture is aligned with one of said first apertures of said cylindrical mounting member when said rotatable valve member is at said second valve position.

9. The apparatus of claim 8, wherein said rotor is secured to said rotatable shaft.

10. The apparatus of claim 8, wherein:

said seal includes a plurality of sealing segments, and

each of said plurality of sealing segments includes only one second aperture defined therein.

11. The apparatus of claim 10, wherein:

said rotor has a fourth aperture defined therein, wherein said fourth aperture is aligned with another of said first apertures of said cylindrical mounting member when said rotatable valve member is located at said second valve position.

12. The apparatus of claim 8, wherein:

said seal includes a cylindrically shaped member, and

said cylindrically shaped member includes a plurality of second apertures defined therein.

13. The apparatus of claim 8, wherein:

when said third aperture aligns with said one of said first apertures, said flow of water is enabled from said water inlet port to said first water outlet port.

14. The apparatus of claim 1, wherein:

said housing includes a first chamber and a second chamber,

said water inlet port is connected to said first chamber,

said first water outlet port is connected to said second chamber,

said rotatable valve member is positioned in said second chamber so as to disable said flow of water from said water inlet port to said first water outlet port when said rotatable valve member is positioned at said second valve position.

15. The apparatus of claim 14, wherein said rotatable valve member includes:

a cylindrical member, and

a plurality of projections secured to said cylindrical member and extending outwardly therefrom.

16. The apparatus of claim 15 wherein said cylindrical member is secured to said rotatable shaft.

17. The apparatus of claim 15, wherein:

said housing includes an interior sidewall, and

each of said plurality of projections contact said interior sidewall.

18. The apparatus of claim 17, wherein:

each of said plurality of projections include a contact tip, and

said contact tip has a substantially cylindrical shape.

19. The apparatus of claim 17, wherein:

said housing includes an internal receptacle which forms an end portion of said water outlet port, and

said internal receptacle defines a guide surface which said rotatable valve member sealingly contacts.

20. The apparatus of claim 1, wherein a water valve is interposed between said main water line and said water inlet port.

21. An automatic washing machine, comprising:

a wash tub;

a dispenser compartment which is connected to said wash tub;

a valve assembly including a housing and a rotatable valve member, said housing having (1) a water inlet port defined therein which is connected to a main water line, and (2) a first water outlet port defined therein which is connected to said dispenser compartment, said rotatable valve member (1) disabling a flow of water from said water inlet port to said first water outlet port when said rotatable valve member is positioned at a first valve position, and (2) enabling said flow of water from said water inlet port to said first water outlet port when said rotatable valve member is positioned at a second valve position; and
