Abstract:
A self-contained vacuum cleaning system comprising:a rectangular housing having a rear wall, two sidewalls, a top wall and a bottom wall, said sidewalls, top and bottom walls being adjacent to said rear wall and perpendicular thereto, said sidewalls and top wall further having a peripheral flange extending outwardly and perpendicularly therefrom, said housing being constructed and arranged so as to define a containment chamber and an evacuation chamber therein;a cover frame assembly in sealing engagement with said housing further including a containment chamber access panel adapted to sealingly engage the perimeter of an aperture in said cover frame assembly, a vacuum hose coupling adapted, on a first outer side thereof, for fluid communication with a vacuum hose and further adapted, on a second inner side thereof, for fluid communication with an air filtering and debris collecting receptacle, and an evacuation chamber exhaust port;vertical baffle assemblies positioned in spaced relation to the sidewalls and rear wall of said housing so as to maintain optimum air flow between said containment chamber and said evacuation chamber;a chamber separating assembly containing, in spaced relation, a supporting grid element, a motor protecting filter element and a motor shroud element, said chamber separating assembly being supported and positioned by integral members in said baffle assemblies;said cleaning system characterized by the containment chamber and evacuation chamber being in stacked relation whereby activation of a motor driven vacuum pump situated in the evacuation chamber causes air to be drawn along a straight-thru flowpath through the containment chamber causing debris to be collected in said receptacle.
