Dish treating appliance with a sprayer
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 closure selectively closes the access opening. At least one dish rack is located within the treating chamber. At least one rotating spray arm is located within the tub, adjacent to and emitting fluid into the at least one dish rack. The at least one rotating spray arm includes a body having at least one fluid spray opening.
1 . An assembly for a dishwasher, the assembly comprising:
a spray arm configured to rotate and emit fluid, the spray arm comprising a body having at least one fluid spray opening, the body defining a main longitudinal body having a periphery and wherein at least one blade is integrally formed with the periphery of the main longitudinal body and a blade body of the at least one blade extends laterally outwardly from the main longitudinal body such that the at least one blade extends upwardly or downwardly from the main longitudinal body;
wherein the at least one blade comprises a pair of blades positioned laterally and longitudinally opposite one another about a center point of the body and wherein a first blade of the pair of blades extends downwardly away from the body and a second blade of the pair of blades extends upwardly away from the body.
2 . The assembly of claim 1 , further comprising a motor operably coupled to and configured to rotationally drive the spray arm to rotate in a first rotational direction and a second rotational direction, wherein rotation of the spray arm in the first rotational direction rotates the at least one blade to move air in a first direction and rotation of the spray arm in the second rotational direction rotates the at least one blade to move air in a second direction.
3 . The assembly of claim 2 , wherein the second rotational direction is opposite of the first rotational direction.
4 . The assembly of claim 2 , further comprising a controller operably coupled to control operation of the motor to selectively rotationally drive the spray arm in the first direction or the second direction.
5 . The assembly of claim 2 , wherein the spray arm is configured to be received within a treating chamber of the dishwasher and wherein rotation of the spray arm in the first rotational direction rotates the at least one blade within the treating chamber to establish air flow in a first direction within the treating chamber and rotation of the spray arm in the second rotational direction rotates the at least one blade to move air within the treating chamber to establish air flow in a second direction within the treating chamber.
6 . The assembly of claim 5 , wherein one of the first direction and the second direction of air flow through the treating chamber is a downward direction of air flow.
7 . The assembly of claim 6 , wherein the other of the first direction and the second direction of air flow through the treating chamber is an upward direction of air flow.
8 . The assembly of claim 1 , wherein the main longitudinal body has an upper surface and a lower surface and wherein the main longitudinal body defines a longitudinal body axis.
9 . The assembly of claim 8 , wherein the main longitudinal body further defines a main plane extending laterally outward from the longitudinal body axis.
10 . The assembly of claim 9 , wherein the at least one blade defines a blade axis defining a blade angle of the blade axis relative to the main plane.
11 . The assembly of claim 10 , wherein the blade angle is between 10° and 80°.
12 . The assembly of claim 1 , wherein the body defines an upper surface, a lower surface, and opposing sides defining the periphery, and wherein the at least one blade extends laterally outward from one of the opposing sides such that the at least one blade extends upwardly or downwardly from the body.
13 . The assembly of claim 1 , wherein the pair of blades are a same size.
14 . The assembly of claim 1 , wherein the at least one blade further comprises a second pair of blades positioned laterally and longitudinally opposite one another about the center point of the body.
15 . The assembly of claim 14 , wherein one blade of the second pair of blades extends downwardly away from the body and an other blade of the second pair of blades extends upwardly away from the body.
16 . An assembly for a dishwasher, the assembly comprising:
a spray arm configured to be received within a treating chamber of the dishwasher, the spray arm configured to rotate and emit fluid, the spray arm comprising a body having at least one fluid spray opening, the body defining a main longitudinal body having a periphery, and wherein at least one blade is integrally formed with the periphery of the main longitudinal body and a blade body of the at least one blade extends laterally outwardly from the main longitudinal body such that the at least one blade extends upwardly or downwardly from the main longitudinal body; and
a motor operably coupled to and configured to rotationally drive the spray arm to rotate in a first rotational direction and a second rotational direction, wherein rotation of the spray arm in the first rotational direction rotates the at least one blade within the treating chamber to establish air flow in a first direction within the treating chamber and rotation of the spray arm in the second rotational direction rotates the at least one blade to move air within the treating chamber in a second direction within the treating chamber.
17 . The assembly of claim 16 , wherein the at least one blade comprises a pair of blades positioned laterally and longitudinally opposite one another about a center point of the body.
18 . The assembly of claim 17 , wherein a first blade of the pair of blades extends downwardly away from the body and a second blade of the pair of blades extends upwardly away from the body.
19 . An assembly for a dishwasher, the assembly comprising:
a spray arm configured to rotate and emit fluid, the spray arm comprising a body having at least one fluid spray opening, the body defining a main longitudinal body having a periphery, and wherein at least one blade is integrally formed with the periphery of the main longitudinal body and a blade body of the at least one blade extends laterally outwardly from the main longitudinal body such that the at least one blade extends upwardly or downwardly from the main longitudinal body, wherein the main longitudinal body has an upper surface and a lower surface, and defines a longitudinal body axis and a main plane extending laterally outward from the longitudinal body axis, wherein the at least one blade defines a blade axis defining a blade angle of the blade axis relative to the main plane, and wherein the blade angle is between 10° and 80°.
