Suction cleaner

Abstract

Abstract THIS INVENTION RELATES TO A SUCTION CLEANER HAVING AN ELONGATED CASING FORMED WITH AN AIR INLET AT ONE END AND AN AIR OUTLET IN A TRANSVERSE WALL AT ITS OPPOSITE END. A CHAMBER, WHICH IS DEFINED IN PART BY THE TRANSVERSE WALL AND A COMBINED FILTER AND DIFFUSER UNIT, RECEIVES AIR FLOWING FROM THE AIR OUTLET. THE COMBINED FILTER AND DIFFUSER UNIT IS U-SHAPED AND HAS AN END WHICH EXTENDS TRANSVERSELY OF THE CLEANER AT THE VICINITY OF THE AIR OUTLET END THEREOF AND SPACED APART SIDES WHICH EXTEND AT OPPOSING SIDES OF THE CLEANER FROM THE CLOSED END TOWARD THE TRANSVERSE WALL. THE U-SHAPED FILTER AND DIFFUSER UNIT, WHICH INCLUDES A U-SHAPED GRATE OR APERTURED FRAME AND A FINE FILTER IN THE FORM OF A LAYER OF MATERIAL POSITIONED WITHIN THE CLOSED END AND SPACED APART SIDES OF THE GRATE, HAS A CROSS-SECTIONAL AREA GREATER THAN THAT OF THE AIR OUTLET AND FILTERS FINE DUST PARTICLES FROM AIR FLOWING INTO THE CHAMBER AND DIFFUSES AND SUBDIVIDES THE FILTERED AIR INTO A MULTIPLICITY OF TINY AIR STREAMS WHICH ARE DEFLECTED UPWARD AND DISCHARGED FROM THE UNIT THROUGH A HORIZONTAL ARC WHICH EXTENDS TRANSVERSELY OF THE CLEANER AND ALONG THE OPPOSING SIDES THEREOF.
