Abstract
The invention relates to a vacuum cleaner comprising a housing and an exhaust opening that is fluidically connected to an overpressure side of a motor/blower unit, which is surrounded by an insulating capsule and which is placed inside a blower housing, via a duct that has a duct section, which is arranged while extending between the insulating capsule and the motor/blower housing. The aim of the invention is to obtain a fluidically optimized duct between the insulating capsule of the motor/blower unit and of a housing part with simple means whose production and assembly are cost-effective. To this end, the invention provides that at least one capsule part of the insulating capsule is joined to a housing part, particularly of the blower housing, while forming a single piece. The largely prevents the formation of perturbing edges due to assembly gaps, and the vacuum cleaner can be cost-effectively produced and assembled with a reduced variety of parts.

40. A vacuum cleaner comprising:
-
a housing having an outer shell wall;
an insulating capsule disposed within the housing and including;
a first capsule part forming capsule walls integrally formed with the housing; and
a second capsule part forming a shell-shaped portion coupled to the capsule walls and at least partially enclosing the insulating capsule;
a blower compartment disposed within the housing and including compartment walls integrally formed with the housing, the compartment walls at least partially surrounding the capsule walls and being disposed between the capsule walls and the outer shell wall;
a blower compartment cover coupled to the compartment walls and at least partially enclosing the blower compartment;
a blower unit disposed within the insulating capsule and generating an air flow for the vacuum cleaner;
an inner channel section formed between the blower unit and the insulating capsule and receiving air flow from the blower unit;
a main flow channel formed between the insulating capsule and the blower compartment and receiving air flow from the insulating capsule;
an inflow opening formed in the blower compartment cover and discharging air flow from the blower compartment; and
an exhaust opening formed in the housing and discharging air flow from the housing.
