Abstract

A method of cleaning a washing machine and components and systems for enabling a user to clean the washing machine are provided. The method includes gaining access to debris that is trapped in otherwise inaccessible and/or concealed areas and/or directing debris out of inaccessible and/or concealed areas. The components include a jet channel that selectively couples to a discharge manifold in use and is removable to provide access to an interior area of the discharge manifold for cleaning. The systems include a removable mount assembly for accessories and a purging system for pumps and other concealed areas. The purging system is configured to discharge purging fluid through a plurality of purging ports and into concealed areas so as to direct debris in the concealed areas out of the concealed areas.

3. The washing machine of claim 2 , wherein moving said jet channel from the locked configuration to the unlocked configuration is further accomplished by sliding a distal end of said jet channel laterally away from a distal end of said discharge manifold.

4. The washing machine of claim 3 , wherein said channel comprises a partition slot for selectively receiving one or more partitioning wall when said jet channel is in the locked configuration to prevent said jet channel from moving to the unlocked configuration.

5. The washing machine of claim 3 , wherein removing said jet channel from the washing machine is accomplished by rotating said distal end of said jet channel away from said distal end of said discharge manifold to move said jet channel into a rotated configuration and then sliding a proximal end of said jet channel laterally away from said proximal end of said discharge manifold until said jet channel is removed from the washing machine.

6. The washing machine of claim 1 , wherein:

said discharge manifold comprises:

a vertical back wall having opposed top and bottom edges; and

top and bottom walls extending forward from respective top and bottom edges of said vertical back wall,

wherein said back, top, and bottom walls of said discharge manifold, together, define at least part of said interior area of said discharge manifold;

said jet channel comprises:

a vertical front panel having opposed top and bottom edges; and

top and bottom flanges extending aft from respective top and bottom edges of said vertical front panel; and

at least a portion of said jet channel is configured to be received by at least a portion of said discharge manifold when said jet channel is in the locked configuration.

7. The washing machine of claim 6 , wherein said top and bottom flanges of said jet channel extend at least partially into said discharge manifold when said jet channel is in the locked configuration such that an outer surface of said top and bottom flanges of said jet channel nests against an inner surface of respective top and bottom walls of said discharge manifold so as to create a seal between said top and bottom flanges of said jet channel and respective top and bottom walls of said discharge manifold.

8. The washing machine of claim 7 , wherein:

said back wall of said discharge manifold is relatively flat;

said top and bottom walls of said discharge manifold each extend relatively perpendicularly but slightly angled outward from said back wall of said discharge manifold such that said top and bottom walls are relatively parallel but slightly angled away from each other;

said front panel of said jet channel is relatively flat; and

said top and bottom flanges of said jet channel each extend relatively perpendicularly outward from said front panel of said jet channel such that said top and bottom flanges are relatively parallel to each other.

9. The washing machine of claim 8 , wherein said jet channel and said discharge manifold are configured such that as said jet channel is inserted further into said discharge manifold, said top and bottom walls of said discharge manifold bias said top and bottom flanges of said jet channel inward towards each other, thereby creating the seal between said top and bottom flanges of said jet channel and respective top and bottom walls of said discharge manifold.

10. The washing machine of claim 6 , wherein:

said discharge manifold further comprises proximal and distal front walls positioned respectively adjacent to said proximal end and a distal end of said discharge manifold, said front walls being displaced from said back wall and extending between said top and bottom walls, thereby defining an opening in said discharge manifold;

said jet channel further comprises proximal and distal recessed panels positioned adjacent to respective proximal and distal ends of said jet channel, said recessed panels extending between said top and bottom flanges and being parallel with, but slightly recessed from, said front panel; and

said recessed panels of said jet channel are configured to engage with respective front walls of said discharge manifold when said jet channel is in the locked configuration so as to create a seal between a front surface of said recessed panels and an aft surface of respective front walls of said discharge manifold.

11. The washing machine of claim 10 , wherein:

said discharge manifold is coupled to a wall of said wash tank;

said wall of said wash tank includes a cutout that extends approximately between said top, bottom, proximal front, and distal front walls of said discharge manifold so as to allow said jet channel to be received by said discharge manifold through said cutout in said wall of said wash tank and said opening in said discharge manifold; and

a front surface of said front panel of said jet channel is relatively flush with an inner surface of said wall of said wash tank when said jet channel is in the locked configuration.

12. The washing machine of claim 10 , wherein said jet channel further includes proximal and distal tabs extending aft of said front panel and being configured to contact said proximal front wall of said discharge manifold in the event a user tries to install said jet channel backwards.

13. The washing machine of claim 1 , further comprising a purging system, the purging system comprising a plurality of purging ports, each purging port being configured to direct purging fluid into a concealed area of the washing machine, and a selector valve in selective fluid communication with each purging port so as to accommodate one or more firing sequences of purging fluid through one or more of said purging ports for directing debris out of said concealed area of the washing machine and towards said wash tank.

14. The washing machine of claim 1 , wherein said jet channel includes one or more jet nozzle and wherein at least some of the washing fluid flowing into said interior area of said discharge manifold flows through said one or more jet nozzle and into said wash tank when said jet channel is in the locked configuration.

15. A method of cleaning an interior area of a discharge manifold of a continuous motion style washing machine, the method comprising:

moving a jet channel from a locked configuration to an unlocked configuration by sliding said jet channel towards a proximal end of said discharge manifold, wherein said jet channel is coupled to said washing machine and secured in position relative to said discharge manifold when said jet channel is in the locked configuration;
