Abstract

A glass bowl for a door assembly of a washer including a housing, a tub inside the housing, the tub having a rotating drum, the door assembly having a see-through portion for viewing into the tub, the see-through portion including the glass bowl, the door assembly pivotably coupled to the housing and movable between an open and closed position. The glass bowl includes a base portion for securing the glass bowl to the door assembly, and a bowl portion configured to extend into the interior of the housing, wherein the bowl portion includes a sidewall extending from the base portion toward the interior of the housing, a first bowl face that faces toward the interior of the housing and an indentation formed in an upper surface of the sidewall that guides at least a portion of water or washing fluid flowing downward onto the glass bowl toward the rotating drum.

the indentation including a pair of guides which bound the indentation on each side of the upper surface of the sidewall and that are disposed at an intersection between each side of the indentation and an adjacent surface of the sidewall,

wherein a surface of the indentation merges with and extends along an upper portion of the inclined second face between the pair of guides, and

wherein the indentation, the pair of guides, and the inclined second face cooperate to guide at least a portion of water or washing fluid flowing downward onto the bowl portion away from the adjacent surface of the sidewall and onto the first bowl face.

2. The glass bowl of claim 1, wherein the pair of guides are configured to guide the water or washing fluid along the indentation and prevent the portion of the water or washing fluid from flowing over and around the remaining portion of the sidewall.

3. The glass bowl of claim 2, wherein each of the guides includes one of a channel, a trough, a curved surface, a lip, and a V-shaped groove.

4. The glass bowl of claim 2, wherein each of the guides includes a first end located nearer the base portion and a second end located nearer the first bowl face.

5. The glass bowl of claim 2, wherein each of the guides extend from the base portion toward the first bowl face.

6. The glass bowl of claim 2, wherein a width of each of the guides is uniform along a length of the guide or a majority of the length of the guide.

7. The glass bowl of claim 4, wherein a width of each of the guides at the first end is less than a width of each of the guides at the second end.

8. The glass bowl of claim 2, wherein each of the guides has a shape extending from the base portion toward the first bowl face that diffuses the water or washing fluid flowing downward onto the inclined second face and the first bowl face of the glass bowl.

9. The glass bowl of claim 2, wherein each of the guides extend along a straight line extending from the base portion toward the first bowl face or along a line extending from the base portion toward the first bowl face that is straight along a majority of a length of the line.

10. The glass bowl of claim 2, wherein each of the guides extend along a curved line extending from the base portion toward the first bowl face.

11. The glass bowl of claim 1, wherein the inclined second face is inclined with respect to a plane of the base portion.

12. The glass bowl of claim 1, wherein an intersection between the indentation and the inclined second face has one of a tapered surface and a curved surface.

13. The glass bowl of claim 1,

wherein each of the pair of guides extends an entire distance from the base portion to the inclined second face.

14. The glass bowl of claim 1,

wherein each of the guides extends a portion of a distance from the base portion to the inclined second face.

15. The glass bowl of claim 1,

wherein each of the guides starts from a point between the base portion and the inclined second face and extends to the inclined second face.

16. The glass bowl of claim 1, wherein the first bowl face includes a concave surface that guides the water or washing fluid toward the rotating drum.

17. The glass bowl of claim 1, wherein an intersection between the first bowl face and the sidewall is one of tapered and curved.

18. The glass bowl of claim 11, wherein the plane of the first bowl face is parallel to the plane of the base portion.

19. The glass bowl of claim 11, wherein the plane of the first bowl face intersects the plane of the base portion at an angle.

20. The glass bowl of claim 1, wherein the sidewall is formed at an angle with respect to a plane of the opening of the housing.

21. The glass bowl of claim 1, wherein the base portion includes a flange that extends radially from the bowl portion in a plane that corresponds to a plane of the door assembly.

22. The glass bowl of claim 21, wherein the flange is configured to be press-fit between an inner ring and a door frame of the door assembly.

23. The glass bowl of claim 21, wherein the flange includes one or more positioning notches for positioning the glass bowl in a correct assembled position for the door assembly.

24. The glass bowl of claim 21, wherein the flange includes a pair of positioning notches that correspond to one of locating and clearance features of an inner ring of the door assembly.

32. The glass bowl of claim 1, wherein an intersection between the indentation and the upper portion of the inclined second face has a curved surface extending upward between the pair of guides.

33. The glass bowl of claim 1, wherein the inclined second face includes a concave surface that guides the water or washing fluid toward the first bowl face.

34. The glass bowl of claim 32, wherein the inclined second face includes a concave surface that guides the water or washing fluid toward the first bowl face.
