Abstract

A laundry treating appliance includes a chassis defining an interior. A rotatable treating chamber is located within the interior and has an access opening. A cover is movably mounted to the chassis for selective movement between opened and closed positions to open and close the access opening. The laundry treating appliance further comprises a spray arm assembly having a spray head.

First claim

What is claimed is:

1. A laundry treating appliance comprising:
a chassis defining an interior;
a rotatable treating chamber located within the interior and having an access opening;
a cover movably mounted to the chassis for selective movement between opened/closed positions to open/close the access opening;
a spray arm assembly positioned underneath the cover and coupled to the cover, the spray arm assembly is moved through a range of motion between raised/lowered positions, the spray arm assembly having a spray head including a scrub surface, the spray arm assembly movable through a range of motion between a first position and a second position in response to the cover being moved between the opened/closed positions; and
a basin underlying the spray head throughout the range of motion and having a drain fluidly coupled with the treating chamber.

2. The laundry treating appliance of claim 1 wherein the basin overlies the access opening.

3. The laundry treating appliance of claim 1 wherein the first position is a lowered position and the second position is a raised position.

4. The laundry treating appliance of claim 3 wherein the spray head confronts the basin when the spray arm assembly is in the lowered position.

5. The laundry treating appliance of claim 4 wherein the spray head is spaced from the basin when the spray arm assembly is in the raised position.

6. The laundry treating appliance of claim 1 wherein the spray head comprises liquid outlets in the scrub surface.

7. The laundry treating appliance of claim 1 wherein liquid is supplied to the spray head in both the first and second positions.

8. The laundry treating appliance of claim 1 wherein the spray arm assembly comprises a hinge defining an axis of rotation about which the spray arm assembly is movable between the first and second positions.

9. The laundry treating appliance of claim 8 wherein the basin is provided at a top wall of the chassis and the spray arm assembly is hingedly mounted relative to the top wall for movement between the first and second positions.

10. The laundry treating appliance of claim 1 wherein the basin is provided at a top wall of the chassis.

11. The laundry treating appliance of claim 1 wherein the rotatable treating chamber rotates about one of a vertical axis of rotation or a horizontal axis of rotation.

12. The laundry treating appliance of claim 1 wherein the basin further defines a liquid inlet.

13. The laundry treating appliance of claim 1 wherein the spray arm assembly further comprises a faucet and a valve controlling liquid flow to the spray head and the faucet.

14. The laundry treating appliance of claim 13 wherein the faucet is operable to emit liquid into the treating chamber when the spray arm assembly is in the second position.

15. A laundry treating appliance comprising:
a chassis defining an interior;
a rotatable treating chamber located within the interior and having an access opening;
a cover movably mounted to the chassis for selective movement between opened/closed positions to open/close the access opening;
a spray arm assembly is coupled to the cover such that when the cover is moved between the opened/closed positions, the spray arm assembly is moved through a range of motion between raised/lowered positions, the spray arm assembly having a spray head overlying the access opening when the spray arm assembly is in the lowered position to spray liquid into the treating chamber; and
a basin underlying the spray head throughout the range of motion and having a drain fluidly coupled with the treating chamber.

16. The laundry treating appliance of claim 15 wherein the spray arm assembly further comprises a faucet operable to emit liquid into the treating chamber when the spray arm assembly is in the raised position.

17. The laundry treating appliance of claim 16 wherein the spray arm assembly comprises a spray arm hinge and the faucet is integrated with the spray arm hinge.

18. The laundry treating appliance of claim 15 further comprising a cover movably mounted to the chassis for selective movement between opened/closed positions to open/close the access opening.

19. The laundry treating appliance of claim 18 wherein the cover comprises a lid and a lid hinge that hingedly mounts the lid to the chassis.

20. The laundry treating appliance of claim 19 wherein the lid hinge and a spray arm hinge have coaxial axes of rotation.
