<p>For mounting in a chamber in the base of an appliance, a cupboard or wall, a housing (10) which is similar in form to a drawer, has a floor level aperture (31 ) at the front for intake of debris. A waste receptacle (34) is removably mounted in the housing, and a first duct (32) leads from the aperture (31 ), preferably upwards to an inlet (33) in an upper region of the waste receptacle. Suction means, such as impeller and drive motor (19), are mounted to the rear of the waste receptacle (34) adjacent the outlet of the receptacle (34) and draw air and entrained debris from adjacent the aperture (31 ) and via the first duct (32) to be deposited in the receptacle (34). Additionally, an enclosure (28) is provided between the waste receptacle outlet and the suction means (19) in which a reservoir containing a volatile deodorising or fragrancing substance is to be mounted so as to minimise any recycling of unpleasant odours back to the room. A second duct (not shown), preferably at each side of the housing (10), extends from the suction means (19) back to the front of the housing (10) to exhaust the air, which typically passes through a filter (37) when exiting the receptacle (34).</p> |
