Abstract

A vacuum cleaner having a nozzle, a motor-fan suction unit pivotably mounted on the nozzle about a horizontal axis, a dust bag enclosing housing of rigid construction mounted on the suction unit to be pivoted therewith and a rigid air passage conduit in the housing extending to the upper portion thereof for suspending a filter bag in the housing together with air inlet passages into the conduit and air outlet passages from the housing both of which are enclosed by the attaching of the housing to the suction unit.

Claims

1. A vacuum cleaner comprising:

a nozzle having an inlet passage means, for dirt laden air;

a motor-fan suction unit having a cylindrical casing pivotably mounted on said nozzle about a horizontal axis of said unit and defining a fan chamber having an entrance means in communication with said inlet passage means and an exit means, whereby dirt laden air is conducted successively through said inlet passage means of the nozzle and said fan chamber by way of its said entrance and exit means;

a rigid upright housing having a lower end removably attached to said casing to be pivotal directly therewith;

an air passage conduit in said housing having a lower end in direct communication with said exit means to receive dirt laden air therefrom and an upper end in an upper portion of said housing;

means at said upper end of said conduit for releasably securing a filter bag in position to receive said dirt laden air and filter the dirt therefrom in passing the air outwardly through the bag into said housing;

housing exit means for conducting the filtered air from said housing, saId lower end of the housing enclosing each of said casing fan chamber exit means and housing exit means; and

an outlet opening in said casing for discharging the filtered air from the vacuum cleaner forwardly through said casing, said housing lower end and casing cooperatively defining means for guiding the discharged air forwardly from said outlet.

2. The vacuum cleaner of claim 1 wherein said means for discharging the filtered air comprises a first air passage means through the casing of said motor-fan suction unit in communication with said housing exit means for conveying said filtered air into said casing and a second air passage means through the casing for discharging the filtered air from the interior of the casing, said second air passage means being movable with said casing relative to said nozzle, said guiding means including a discharge vent opening in said lower end of the housing forwardly of the casing second air passage means.

3. The vacuum cleaner of claim 1 wherein said cylindrical casing for said suction unit is horizontally disposed and supports at a top portion thereof said fan chamber exit means and a filtered air inlet from said housing exit means to the interior of said casing, and means for attaching said lower end of the housing to said top portion of said casing to enclose both said exit means.
