Abstract

A dish treating appliance can include a tub at least partially defining a treating chamber and having an access opening providing access to the treating chamber, a closure selectively closing the access opening, a condenser including an inlet, an outlet, and a condensing passage defining a serpentine path with multiple turns fluidly coupling the inlet and the outlet, with the inlet fluidly coupled to the treating chamber, the outlet fluidly coupled to ambient air, and multiple ambient air inlets provided in the serpentine path, and a blower fluidly coupled to the condenser flowing a volume of air through the serpentine path of the condenser, and at least one separator wall located within the condenser.

First claim

What is claimed is:

1. A dish treating appliance for treating dishes according to an automatic cycle of operation, the dish treating appliance comprising:
a tub at least partially defining a treating chamber and having an access opening providing access to the treating chamber;
a closure selectively closing the access opening;
a condenser comprising an inlet, an outlet, and a condensing passage defining a serpentine path with multiple turns fluidly coupling the inlet and the outlet, with the inlet fluidly coupled to the treating chamber, the outlet fluidly coupled to ambient air, and multiple ambient air inlets provided in the serpentine path; and
a blower fluidly coupled to the condenser flowing a volume of air through the serpentine path of the condenser; and
at least one separator wall located within the condenser to at least partially form multiple flow paths through the condenser;
wherein the multiple ambient air inlets provided in the serpentine path reduce an overall humidity of the volume of air flowing through the serpentine path while simultaneously condensing humidity from the volume of air in the condensing passage.

2. The dish treating appliance of claim 1 further comprising at least one curved wall located within the serpentine path to at least partially forming the multiple flow paths in at least one of the multiple turns.

3. The dish treating appliance of claim 2 further comprising an angled wall at least partially forming the multiple flow paths.

4. The dish treating appliance of claim 3 wherein the angled wall extends from a side of the condenser toward the curved wall.

5. The dish treating appliance of claim 4 wherein at least one of the multiple ambient air inlets is located on a downstream side of the angled wall.

6. The dish treating appliance of claim 5 wherein the at least one of the multiple ambient air inlets is located at a junction of the angled wall and side of the condenser.

7. The dish treating appliance of claim 1 further comprising a water wall disposed below the inlet.

8. The dish treating appliance of claim 7 wherein the water wall is disposed upstream of the at least one separator wall.

9. The dish treating appliance of claim 1 further comprising multiple separator walls.

10. The dish treating appliance of claim 9 wherein the multiple separator walls are disposed downstream of each other.

11. The dish treating appliance of claim 1 wherein the at least one separator wall is disposed at a junction of the inlet and the condensing passage.

12. The dish treating appliance of claim 1 further comprising multiple curved walls and multiple angled walls wherein each angled wall has a complementary curved wall.

13. The dish treating appliance of claim 1 further comprising a turning wall disposed adjacent the outlet configured to turn the multiple flow paths towards the outlet.

14. A dish treating appliance for treating dishes according to an automatic cycle of operation, the dish treating appliance comprising:
a tub at least partially defining a treating chamber and having an access opening providing access to the treating chamber;
a closure selectively closing the access opening;
a condenser comprising an inlet, an outlet, and a condensing passage defining a serpentine path with multiple turns fluidly coupling the inlet and the outlet, with the inlet fluidly coupled to the treating chamber, the outlet fluidly coupled to ambient air, and multiple ambient air inlets provided in the serpentine path; and
a blower fluidly coupled to the condenser flowing a volume of air through the serpentine path of the condenser; and
a plurality of separator walls disposed at a junction of the inlet and the condensing passage to at least partially form multiple flow paths through the condenser;
wherein the multiple ambient air inlets provided in the serpentine path reduce an overall humidity of the volume of air flowing through the serpentine path while simultaneously condensing humidity from the volume of air in the condensing passage.

15. The dish treating appliance of claim 14 further comprising at least one curved wall located within the serpentine path to at least partially forming the multiple flow paths in at least one of the multiple turns.

16. The dish treating appliance of claim 15 further comprising an angled wall at least partially forming the multiple flow paths.

17. The dish treating appliance of claim 16 wherein the angled wall extends from a side of the condenser toward the curved wall.

18. The dish treating appliance of claim 17 wherein at least one of the multiple ambient air inlets is located on a downstream side of the angled wall.

19. The dish treating appliance of claim 18 wherein the at least one of the multiple ambient air inlets is located at a junction of the angled wall and side of the condenser.

20. The dish treating appliance of claim 14 further comprising a water wall disposed below the inlet.
