Abstract

A spray fill device for delivering water to a washing machine is provided. The spray fill device includes a body defining an inlet, an outlet port, a mounting port, and a plurality of outlet apertures in flow communication with the inlet. The spray fill device also includes a first valve coupled to the inlet, the valve configured to control a flow rate of water into the inlet. The spray fill device also includes a pressure relief mechanism coupled to the mounting port, the pressure relief mechanism inhibiting flow through the outlet port when a pressure within the body is less than a predetermined pressure.

Claims (33)

1. A spray fill device for delivering water to a washing machine, said spray fill device comprising:

a body defining an inlet, an outlet port, a mounting port, and a plurality of outlet apertures in flow communication with said inlet;

a first valve coupled to said inlet, said first valve configured to control a flow rate of water into said inlet; and

a pressure relief mechanism coupled to said mounting port, in a first position said pressure relief mechanism inhibiting flow through said outlet port such that water flows through said plurality of outlet apertures when a pressure within said body is less than a predetermined pressure, and in a second position said pressure relief mechanism permitting water flow through said outlet port and said plurality of outlet apertures when said pressure within said body is at least equal to said predetermined pressure.

2. A spray fill device in accordance with claim 1 further comprising a second valve and a third valve coupled to said inlet, said second and third valves configured to supply a greater flow rate of water to said inlet during a wash fill than the flow rate of water through said first valve.

3. A spray fill device in accordance with claim 2 wherein said first, second, and third valves configured to deliver water at a first flow rate in a wash cycle and a second flow rate in a rinse cycle, said first flow rate greater than said second flow rate.

4. A spray fill device in accordance with claim 1 wherein said body comprises a cap positioned adjacent said mounting port and configured to cover said mounting port.

5. A spray fill device in accordance with claim 1 wherein said pressure relief mechanism comprises a member in flow communication with said mounting port, said member movable from a first position wherein flow through said outlet port is inhibited and a second position wherein flow through said outlet port is enabled.

6. A spray fill device in accordance with claim 5 wherein said pressure relief mechanism comprises a biasing member configured to bias said member toward said first position.

7. A spray fill device in accordance with claim 5 wherein said member is movable from said first position to said second position in response to a pressure within said body.

8. A spray fill device in accordance with claim 1 wherein flow through said outlet port is enabled during a wash fill.

9. A spray fill device in accordance with claim 1 wherein flow through said outlet port is inhibited during a rinse cycle.

10. A spray fill device in accordance with claim 1 wherein said body defines an elongated channel having first and second opposite ends, said first end including a first outlet port and a first pressure relief mechanism and said second end including a second outlet port and a second pressure relief mechanism, said plurality of outlet apertures arranged in rows between said first and second ends.

11. A spray fill device in accordance with claim 1 wherein said plurality of outlet apertures are formed at angles through said body from sixty to ninety degrees with respect to a horizontal plane when said spray fill device is mounted in the washing machine.

12. A washing machine comprising:

a cabinet;

a tub positioned within said cabinet;

basket rotatably mounted within said tub; and

a spray fill device mounted within said cabinet and positioned to introduce water into said basket at a controlled flow rate, said spray fill device comprising:

a body defining an inlet, an outlet port, a mounting port, and a plurality of outlet apertures in flow communication with said inlet;

a first valve coupled to said inlet, said valve configured to control a flow rate of water into said inlet; and

a pressure relief mechanism coupled to said mounting port, in a first position said pressure relief mechanism inhibiting flow through said outlet port such that water flows through said plurality of outlet apertures when a pressure within said body is less than a predetermined pressure, and in a second position said pressure relief mechanism permitting water flow through said outlet port and said plurality of outlet apertures when said pressure within said body is at least equal to said predetermined pressure.

13. A washing machine in accordance with claim 12 wherein said pressure relief mechanism is activated by water within said spray fill device, said pressure relief mechanism configured to increase a flow rate through said spray fill device during a wash fill.

14. A washing machine in accordance with claim 12 further comprising:

a second valve and a third valve coupled to said spray fill device; and

a controller operatively coupled to said first, second, and third valves and configured to control said first, second, and third valves based on steps in a wash cycle.

15. A washing machine in accordance with claim 14 wherein said controller configured to activate said first valve during a rinse cycle and said second and third valves during a wash fill.

16. A washing machine in accordance with claim 12 wherein said spray fill device is configured to deliver water at a first flow rate during a wash cycle and a second flow rate during a rinse cycle, said first flow rate greater than said second flow rate.

17. A washing machine in accordance with claim 16 wherein said controller configured to rotate said basket at a rate of less than eighty revolutions per minute when said spray fill device delivers water at the first flow rate.

18. A spray fill device for delivering water to a washing machine, said spray fill device comprising:

body defining an inlet, an elongated channel having a first end and an opposing second end, each of said first end and said second end defining a respective outlet port and a respective mounting port, said elongated channel further defining a plurality of outlet apertures in flow communication with said inlet, said plurality of outlet apertures arranged in rows between said first end and said second end;

a valve coupled to said inlet, said valve configured to control a flow rate of water into said inlet; and

a pressure relief mechanism positioned at each of said first end and said second end, each pressure relief mechanism coupled with respect to said respective mounting port, said pressure relief mechanism inhibiting flow through said respective outlet port when a pressure within said body is less than a predetermined pressure.
