Laundry appliance having an impeller with a removable filtration structure
A laundry appliance includes a drum that is rotationally operable within a tub and a rotator that is rotationally operable relative to the drum. The rotator includes an impeller that is axially fixed with respect to the drum and includes a receiver, a removable agitator that is selectively coupled with the receiver, and a filtration structure that is disposed at least within the removable agitator.
1 . A laundry appliance comprising:
a drum that is rotationally operable within a tub; and
a rotator that is rotationally operable relative to the drum, the rotator comprising:
an impeller that is axially fixed with respect to the drum and including a receiver;
a removable agitator that is selectively coupled with the receiver; and
a filtration structure that is disposed at least within the receiver of the impeller, wherein the filtration structure is fully defined within the receiver of the impeller and includes a filter cartridge that moves vertically between a first filtering position and a second filtering position, the first filtering position defined when the removable agitator is coupled with the receiver and the second filtering position defined when the removable agitator is detached from the receiver.
2 . The laundry appliance of claim 1 , wherein the filter cartridge is biased toward the second filtering position.
3 . The laundry appliance of claim 2 , wherein the impeller includes a spring that is disposed within the receiver for biasing the filter cartridge toward the second filtering position.
4 . The laundry appliance of claim 3 , wherein the spring is attached to a structural plate that engages a bottom surface of the filter cartridge.
5 . The laundry appliance of claim 4 , wherein the structural plate includes a plurality of plate openings that allow process fluid to pass therethrough.
6 . The laundry appliance of claim 2 , wherein the filter cartridge includes a filter member that is attached to a cap.
7 . The laundry appliance of claim 6 , wherein the filter member and the cap are selectively secured together to define a filtration chamber therein.
8 . The laundry appliance of claim 7 , wherein the cap includes a top set of apertures that allow process fluid to enter into the filtration chamber, and wherein the filter member includes a filter screen that separates particulate from the process fluid to define filtered process fluid that is directed through plate apertures of a structural plate of the receiver.
9 . The laundry appliance of claim 1 , wherein the receiver includes a plurality of apertures within an outer wall of the receiver, and wherein the filter cartridge in the second filtering position at least partially obstructs the plurality of apertures.
10 . The laundry appliance of claim 1 , wherein the filter cartridge includes a solid outer wall and a top set of filtering apertures, wherein the first filtering position is characterized by the top set of filtering apertures being in communication with side apertures of the receiver.
11 . The laundry appliance of claim 10 , wherein the second filtering position is characterized by the solid outer wall blocking the side apertures of the receiver and the top set of filtering apertures positioned proximate a top of the receiver.
12 . A laundry appliance comprising:
a drum that is rotationally operable within a tub; and
a rotator that is rotationally operable relative to the drum, the rotator comprising:
an impeller that is axially fixed with respect to the drum and including a receiver;
a removable agitator that is selectively coupled with the receiver; and
a filtration structure that is defined by the receiver and operable between a first filtering position characterized by the removable agitator being in an installed position, and a second filtering position characterized by the removable agitator separated from the receiver, wherein the filtration structure includes a filter cartridge that is disposed within the receiver having a plurality of flow apertures, wherein attachment of the removable agitator moves the filter cartridge to the first filtering position defined by a movement of process fluid through the plurality of flow apertures, and wherein separation of the removable agitator from the receiver moves the filter cartridge to the second filtering position defined by a removable cassette interfering with the plurality of flow apertures and the movement of the process fluid through a top set of filtering apertures of the filter cartridge.
13 . The laundry appliance of claim 12 , wherein the filter cartridge is selectively removable from the receiver from the second filtering position.
14 . The laundry appliance of claim 12 , wherein each of the removable agitator and the filter cartridge are selectively removable from the receiver.
15 . The laundry appliance of claim 12 , wherein the impeller includes a spring that is disposed within the receiver for biasing the filter cartridge toward the second filtering position.
16 . The laundry appliance of claim 15 , wherein the spring is attached to a structural plate that engages a bottom surface of the filter cartridge.
17 . The laundry appliance of claim 16 , wherein the structural plate includes a plurality of plate openings that allow the process fluid to pass therethrough.
18 . The laundry appliance of claim 12 , wherein the filter cartridge includes a filter member that is attached to a cap.
19 . The laundry appliance of claim 18 , wherein the filter member and the cap are selectively secured together to define a filtration chamber therein.
20 . The laundry appliance of claim 19 , wherein the cap includes a top set of apertures that allow the process fluid to enter into the filtration chamber, and wherein the filtration member includes a filter screen that separates particulate from the process fluid to define filtered process fluid that is directed through a structural plate of the receiver.
