Abstract
A baffle assembly for a hollow cavity is disclosed. The baffle assembly includes a labyrinth that defines a tortuous drain passageway. The baffle assembly includes a vertical portion that abuts an expandable material to reduce the transmission of noise and other vibrations.
Claims11
A baffle assembly, comprising:
- a substantially planar carrier having an upper surface and a lower surface;
- and
- a drain housing extending upwardly from said upper surface, wherein said drain housing includes a cavity interconnecting a fluid inlet and a fluid outlet, and a generally vertically oriented web portion that extends from an interior surface of the drain housing to define at least a portion of a drain path through said cavity,
- wherein said drain housing includes a plurality of staggered web portions that extend from an interior surface of said drain housing to define a labyrinth drain path, and wherein the labyrinth drain path is defined by a labyrinth drain path portion and a generally vertical portion, and wherein the entire labyrinth drain path portion is oriented parallel to a generally horizontal plane.
1 more element
A drain housing for dissipating sound therein, comprising:
- a generally vertically oriented planar web portion that extends from an interior surface of said drain housing to define at least a portion of a drain path through said drain housing, wherein said web portion defines two legs of said drain path, wherein said two legs of said drain path flow in opposite directions,
- wherein said drain housing includes a plurality of staggered web portions that extend from an interior surface of said drain housing to define a labyrinth drain path. and wherein the labyrinth drain path is defined by a labyrinth drain path portion and a generally vertical portion, and wherein the entire labyrinth drain path portion is oriented parallel to a generally horizontal plane.
