A cover assembly for sealing a dishwasher drawer includes a rigid, movable cover casing that frames a flexible sealing cover which is capable of receiving and covering tall dishes extending beyond a height of the drawer. Rocker arms are placed on each perimeter edge of the cover casing, and pivot to raise and lower the casing onto the drawer so that the sealing cover seals a wash chamber therein. A seal adhered to a bottom of the cover casing presses against a lip of the drawer to prevent leakage of wash fluid circulated therein.

A cover assembly for a dishwasher drawer comprising: a stationary frame affixed to an interior top wall surface of an enclosure case of said dishwasher drawer;a movable cover casing framing a flexible sealing cover; anda plurality of rocker arms distributed about a perimeter of said frame pivotal
1. A cover assembly for a dishwasher drawer comprising: a stationary frame affixed to an interior top wall surface of an enclosure case of said dishwasher drawer;a movable cover casing framing a flexible sealing cover; anda plurality of rocker arms distributed about a perimeter of said frame pivotally linking said cover casing to said frame for movement between an open position remote from the drawer and a closed position in sealing engagement with the drawer, wherein each of said rocker arms includes:a substantially I-shaped member including a first bar contained in a recess on an underside of said frame;a second bar contained in a corresponding recess on an upper surface of said cover casing, wherein said second bar is substantially parallel to said first bar;a leg substantially perpendicular to both on said first bar and said second bar such that said leg protrudes from said underside of said frame and from said upper surface of said cover casing;wherein both said first bar and said second bar rotate in said respective recesses so that said leg moves said cover casing toward and away from said frame;wherein both said second bar and said first bar remain in horizontal planes of said cover casing and said frame. 2. The cover assembly of claim 1, including at least twelve rocker aims wherein at least three rocker arms are included on each edge of said frame, and wherein each of said rocker arms are oriented so that they pivot in unison. 3. The cover assembly of claim 1, wherein said cover casing comprises: an outer, elevated portion; an inner, depressed portion; and a groove extending along an underside of said elevated portion; and a seal adhered to a bottom wall of said groove and protruding outwards therefrom. 4. The cover assembly of claim 3, wherein in said closed position said rocker aims push said seal into sealing engagement with a lip of the drawer to provide a seal between said cover assembly and said drawer. 5. The cover assembly of claim 4, further comprising a retaining wall congruent with a sidewall of said inner depressed portion, said retaining wall prevents said leg of said rocker arm from travelling past a 90-degree angle. 6. The cover assembly of claim 1, further including at least one deployment member that protrudes outwardly from a rear edge of said cover for engagement by the drawer when the drawer is moved into the enclosure case. 7. The cover assembly of claim 6, wherein said at least one deployment member includes a block wall, said block wall extends downwardly past an outermost region of said cover into the path of the drawer. 8. The cover assembly of claim 7, wherein the drawer contacts said block wall as it retracts inwardly within the enclosure case, wherein said rocker aims swing said cover casing downwardly until said seal is lowered onto presses onto top edges of the drawer. 9. The cover assembly of claim 1, further comprising: at least one spring biasing member operative to bias said sealing cover toward its open position. 10. The cover assembly of claim 9, wherein said biasing member comprises at least one tension spring which extends when said cover casing is moved toward its closed position. 11. The cover assembly of claim 1, wherein said recesses comprise pockets including: a front wall that accommodates said first bar and said second bar; and at least one recess within said front wall to accommodate said leg as said leg rotates. 12. A cover assembly for sealing the wash chamber of a dishwasher drawer removably contained in an appliance enclosure case, said cover assembly comprising: a rigid, movable cover casing framing a pliable sealing cover;at least one rocker arm mounted on perimeter edges of said cover casing;a stationary, rigid frame affixed to an interior top wall surface of said enclosure case, wherein said rocker arm pivots between said frame and said cover casing to lower said cover casing over the drawer so that said sealing cover seals the wash chamber within the drawer,wherein each rocker arm includes:a first bar contained in a pocket on an underside of said frame;a second bar contained in a pocket on an upper surface of said cover casing, wherein said second bar is substantially parallel to said first bar;a leg substantially perpendicular to both said first bar and said second bar such that said leg protrudes from said underside of said frame and from said upper surface of said cover casing;wherein both said first bar and said second bar pivot in said respective pockets so that said leg moves said cover casing toward and away from said frame;wherein both said second bar and said first bar remain in a horizontal plane of said cover casing and said frame, said leg pivots between an angled portion and a substantially vertical position;whereby said rocker arms in said vertical position press a seal of said cover assembly into sealing engagement with a lip of said drawer to seal the gap between said cover assembly and said drawer. 13. The cover assembly of claim 12, comprising a plurality of rocker arms, wherein at least three rocker arms are included on each said edge of said cover casing, wherein each of said rocker arms are oriented so that they pivot in unison. 14. The cover assembly of claim 12, wherein said cover casing comprises: an outer, elevated portion; an inner, depressed portion; a groove extending along an underside of said elevated portion; and, a seal adhered to a bottom wall of said groove and protruding outwardly therefrom. 15. The cover assembly of claim 14 further including a retaining wall congruent with a sidewall of said inner depressed portion, said retaining wall precludes a leg of said rocker arm from travelling past a 90-degree angle. 16. The cover assembly of claim 12, further including at least one deployment member that protrudes outwardly from a rear edge of said cover casing to move said cover assembly when the drawer moves into the enclosure case. 17. The cover assembly of claim 16, wherein said at least one deployment member includes a block wall, said block wall extends downwardly past an outermost region of said cover casing and below an edge of said seal. 18. The cover assembly of claim 17, wherein the drawer contacts said block wall as it retracts inwardly within the enclosure case, wherein said rocker aims swing said cover casing inwardly and downwardly until said seal sealingly engages the drawer. 19. The cover assembly of claim 12, wherein said pockets include: a curved front wall that accommodates a cylindrical configuration of said first bar and said second bar; and, a recess formed in said curved front wall to accommodate said leg. 20. A cover assembly for sealing the wash chamber of a dishwasher drawer removably contained in an appliance enclosure case, said cover assembly comprising: a rigid, movable cover casing framing a pliable sealing cover;at least one rocker arm mounted on perimeter edges of said cover casing;a stationary, rigid frame affixed to an interior top wall surface of said enclosure case, wherein said rocker arm pivots between said frame and said cover casing to lower said cover casing over the drawer so that said sealing cover seals the wash chamber within the drawer;at least one spring post protruding from said frame;at least one corresponding spring post protruding from said cover casing; and,at least one tension spring which pulls said sealing cover upwardly and away from the drawer. 21. The cover assembly of claim 20, wherein said tension spring extends when said cover casing moves toward the drawer.
