Abstract
A dishwasher for treating dishes according to an automatic cycle of operation includes a tub at least partially defining a treating chamber with an access opening. A door selectively closes the access opening. At least one dish rack is located within the treating chamber. A rotating arm assembly is located within the tub below the at least one dish rack and has a rotatable hub with a liquid conduit. A spray arm is carried by the hub and fluidly coupled to the liquid conduit. An air mixing arm is carried by the hub.
Claims19
A dishwasher for treating dishes according to an automatic cycle of operation, the dishwasher comprising:
- a tub at least partially defining a treating chamber with an access opening;
- a door selectively closing the access opening;
- at least one dish rack located within the treating chamber;
- an air inlet fluidly coupled to the treating chamber;
- an air outlet fluidly coupled to the treating chamber;
- a rotating arm assembly located within the tub below the at least one dish rack and having a rotatable hub with a liquid conduit, a spray arm carried by the rotatable hub and fluidly coupled to the liquid conduit, and an air mixing arm carried by the rotatable hub and rotationally spaced from the spray arm;
- and
- a motor having an output shaft extending into the tub, the output shaft operably coupled to the rotatable hub to provide a rotational driving force thereto and wherein rotation of the rotatable hub rotates the air mixing arm to move air within the treating chamber whereby air is drawn in through the air inlet and is expelled out the air outlet to establish air flow through the treating chamber.

A dishwasher for treating dishes according to an automatic cycle of operation, the dishwasher comprising:
- a tub at least partially defining a treating chamber with an access opening;
- a door selectively closing the access opening;
- at least one dish rack located within the treating chamber;
- a rotating arm assembly located within the tub below the at least one dish rack and having a rotatable hub with a liquid conduit, a spray arm carried by the rotatable hub and fluidly coupled to the liquid conduit, and an air mixing arm carried by the rotatable hub and rotationally spaced from the spray arm, the air mixing arm comprising multiple, parallel blades;
- wherein rotation of the rotatable hub rotates the air mixing arm to move air within the treating chamber to establish air flow through the treating chamber;
- a first motor rotationally driving the spray arm;
- and
- a second motor rotationally driving the air mixing arm, independently of the first motor, and at a speed greater than the first motor drives the spray arm and wherein the second motor comprises an output shaft operably coupled to and extending from the second motor and into the tub.
