Abstract
A vacuum cleaner has a housing (1) in which a dust chamber (17) and a motor chamber (13) are accommodated. The motor chamber (13) is connected to the dust chamber (17) via a motor inlet (15). The housing (1) includes a lower housing part (37) and an upper housing part (39). The dust chamber (17) is present at a side (43) of the upper housing part (39) which faces away from the lower housing part (37), and is bounded by a depression (41) in the upper housing part (39) which faces the lower housing part (37). The motor chamber (13) includes a chamber (45) of the upper housing part (39) which is present at a side (49) of the upper housing part (39) which faces the lower housing part (37). The depression (41) defines an unmolding direction (X) of the upper housing part (39). The chamber (45) has an unmolding direction (X') which is parallel to the unmolding direction (X) of the upper housing part (39), while the motor inlet (15) is provided in the upper housing part (39) and extends in a plane which intersects the unmolding direction (X). The upper housing part (39) and the lower housing part (37) can be manufactured by means of an injection molding process with a minimum number of auxiliary mold pieces or inserts, the lower housing part (37) being of a very simple construction.
