Abstract
A laundry appliance includes a tub having a rear wall. A drum is rotationally operable within the tub. An air flow path extends through an air flow port defined within the rear wall. A lint filter is positioned within the air flow port. A fluid spray system extends through the rear wall and directs a flow of fluid over the air flow port and the lint filter in a direction generally parallel with an inside surface of the rear wall.
Claims13
A laundry appliance comprising:
- a tub having a rear wall;
- a drum that is rotationally operable within the tub;
- an air flow path that extends through an air flow port defined within the rear wall, wherein a lint filter is positioned within the air flow port;
- a fluid spray system that extends through the rear wall and directs a flow of fluid over the air flow port and the lint filter in a direction generally parallel with an inside surface of the rear wall, wherein the fluid spray system includes a directing nozzle that directs the flow of fluid in a fan-shaped configuration over the air flow port;
- and
- a reinforcing panel attached to a back surface of the rear wall, wherein the air flow path and the fluid spray system extend through the rear wall and the reinforcing panel, wherein the directing nozzle extends through a utility opening of the reinforcing panel and a fluid opening of the rear wall, and wherein the utility opening and the fluid opening are concentric with respect to the directing nozzle.

A laundry appliance comprising:
- a tub that defines a laundry treatment space and includes a rear wall;
- an air flow path that extends from the tub and through an air flow port defined within the rear wall of the tub;
- a lint filter disposed within the air flow path that entraps particles of lint;
- and
- a fluid spray system that extends through the rear wall and directs a flow of fluid along an inside surface of the rear wall and across a surface of the lint filter to separate particles of lint from the lint filter and dispose the particles of lint within the laundry treatment space, wherein the fluid spray system includes a directing nozzle that directs a fan-shaped spray of the fluid within the laundry treatment space and across the surface of the lint filter, and wherein a reinforcing panel is attached to a back surface of the rear wall, and wherein the air flow port and the directing nozzle extend through each of a of the reinforcing panel and a fluid opening of the rear wall, wherein the utility opening and the fluid opening are concentric with and are in a close engagement with the directing nozzle.

An air flow system for an appliance, the air flow system comprising:
- a blower that directs process air through an air flow path;
- a tub that defines a laundry treatment space, wherein the air flow path extends through the laundry treatment space and through a rear wall of the tub at an air flow port;
- a lint filter positioned within the air flow port, wherein the lint filter captures lint particles on a filter surface that partially defines the laundry treatment space;
- and
- a fluid spray system that extends through the rear wall and directs a flow of fluid along an inside surface of the rear wall and across the filter surface, wherein a directing nozzle of the fluid spray system directs the flow of fluid generally away from a central axis of the tub and toward an outer edge of the rear wall, wherein a reinforcing panel is attached to a back surface of the rear wall, and wherein the air flow port and the directing nozzle extend through each of the reinforcing panel and the rear wall, wherein the directing nozzle extends through a utility opening of the reinforcing panel and a fluid opening of the rear wall, and wherein the utility opening and the fluid opening are in a close engagement with the directing nozzle.
