A scroll assembly for use with a fluid machine, such as a wet/dry vacuum appliance, is described. Such scroll assembly may include a base portion, a cover portion configured to couple to the base portion, and a cavity between the base portion and the cover portion, wherein the cover portion and the base portion collectively form a labyrinth seal when coupled together, and wherein the labyrinth seal at least partially circumscribes the cavity. A vacuum appliance may include a scroll assembly coupled at least partially therein. A method of exhausting air from a vacuum appliance may include energizing a vacuum motor, thereby drawing air into the scroll assembly, allowing the air to contact a flow splitter, and allowing the air to exit the vacuum appliance.

1. A scroll assembly for a vacuum appliance, comprising: a base portion having an opening there through;a cover portion having an air inlet and configured to couple to the base portion, thereby defining a cavity between the base portion and the cover portion; and,a flow splitter coupled within the cavity;wherein the cover portion and the base portion collectively form a labyrinth seal when the cover portion and the base portion are coupled together; andwherein the labyrinth seal at least partially circumscribes the cavity. 2. The scroll assembly of claim 1, wherein one of the scroll and cover portions includes a channel having two walls, and wherein the other of the scroll and cover portions includes a rib configured to sealingly engage the channel. 3. The scroll assembly of claim 2, further comprising a plurality of ribs configured to sealingly engage the channel. 4. The scroll assembly of claim 1, wherein the opening is configured to couple with a vacuum motor. 5. The scroll assembly of claim 1, further comprising a sound-deadening barrier coupled within the cavity and disposed radially interior of the labyrinth seal, the barrier at least partially circumscribing the opening in the base portion. 6. A vacuum appliance, comprising: a lid adapted to couple to a collection drum, the lid having an interior side, an exterior side, and an exhaust port there through;a scroll assembly as claimed in claim 1 coupled to the lid so that the air inlet is in fluid communication with the exhaust port; anda vacuum motor coupled to the lid, the vacuum motor having an impeller assembly disposed at least partially within the cavity of the scroll assembly. 7. The vacuum appliance of claim 6, further comprising a collection drum coupled to the interior side of the lid and wherein the scroll assembly is at least partially disposed inside the collection drum. 8. The vacuum appliance of claim 6, wherein the vacuum appliance is a wet/dry vacuum appliance. 9. A method of exhausting air from a vacuum appliance as claimed in claim 6 and having a flow splitter coupled within the cavity and fluidicly disposed between the air inlet of the cover portion and the exhaust port of the lid, the method comprising: energizing the vacuum motor, thereby drawing air through the air inlet of the cover portion and into the cavity of the scroll assembly;allowing the air to contact the flow splitter, thereby distributing the air into a plurality of flow paths; andallowing the air to exit the vacuum appliance through the exhaust port. 10. The method of claim 9, further comprising distributing the air into a plurality of substantially equal flow paths across the exhaust port. 11. A vacuum appliance comprising: a collection drum having at least one side, a base, and an open top;a motor operable to create a vacuum in the collection drum;a lid removably attached to the open top of the collection drum, the lid having a motor mount member with the motor attached thereto, and a scroll assembly attached to the lid, the scroll assembly comprising:a base portion having an opening formed there through;a cover portion having an air inlet and configured to couple to the base portion, thereby defining a cavity between the base portion and the cover portion;wherein the cover portion and the base portion collectively form a labyrinth seal when the cover portion and the base portion are coupled together; andwherein the labyrinth seal at least partially circumscribes the cavity. 12. The vacuum appliance of claim 11, wherein the vacuum motor has an impeller assembly disposed at least partially within the cavity of the scroll assembly. 13. The vacuum appliance of claim 11, wherein the collection drum includes a drain opening extending therethrough a wall of the drum. 14. The vacuum appliance of claim 11, wherein the opening in the base portion of the scroll assembly is sized to accept a shaft extending therethrough. 15. The vacuum appliance of claim 11, further comprising a blower wheel, wherein the motor includes a shaft having the blower wheel attached thereto. 16. The vacuum appliance of claim 11, further comprising a filter assembly attached to a face of the lid and extending downwardly into the collection drum. 17. The vacuum appliance of claim 11, further comprising a motor gasket sized to seal an interface between a section of the lid and the motor to prevent air flow from escaping through an aperture, such as a shaft aperture. 18. The vacuum appliance of claim 11, wherein the scroll assembly further comprises an air flow splitter oriented to divide the air flow during vacuum operation across the exhaust port. 19. The vacuum appliance of claim 18, wherein the air flow splitter is made of a sound absorbing material.
