Abstract:
A vacuum cleaner comprising a housing (1), in which a dust compartment (5), which can be closed by a dust compartment cover and is designed to receive a dust interceptor (6), and a fan compartment (7) for receiving a motor-driven fan unit (8) are configured. The vacuum cleaner also comprises a receiving compartment (16) for attachments (17), which extends below the dust compartment (5) and/or the fan compartment (7) and can be accessed by means of an opening (18) in the housing (1). The aim of the invention is to permit users to remove attachments (17) easily from the receiving compartment (16) that is located below the dust compartment (5) and the fan compartment (7). To achieve this, the opening(s) (18) is/are provided in a lateral wall (19) of the housing (1). This permits attachments (17) to be removed, without bringing the vacuum cleaner out of its normal operating position.
Abstract:
A filter stop for a vacuum cleaner contains a dust chamber that is closable with a lid and receives a dust bag with a reinforcement plate in a specific fitting position. The filter stop has a base plate that is movable between two stopping positions parallel to the direction in which the reinforcement plate of the dust bag is inserted into the dust chamber. The filter stop is also provided with a swiveling lever that can be brought into a position activating the vacuuming function of the vacuum cleaner by the reinforcement plate when the dust bag is correctly positioned. The swiveling lever is in a position preventing the vacuuming function from being activated when the dust bag is not correctly positioned. The filter stop can be brought into a stop position activating the vacuuming function exclusively when the swiveling lever is actuated by a shoulder of the reinforcement plate.
Abstract:
A vacuum cleaner, comprising a housing, in which a dust chamber is embodied for housing a dust separator, which may be sealed by means of a dust chamber lid, mounted on the housing and a housing for accessory pieces which can be closed by the dust chamber lid. According to the invention, the contamination of the accessory pieces by dust from the dust chamber may be prevented, whilst maintaining easy access to the accessory pieces by means of the dust chamber lid, whereby the housing is embodied as an adjoining chamber, directly adjacent to the dust chamber which is separated from the dust chamber in a dust-tight manner by means of a separating wall. The above has the advantage of permitting a user to remove an accessory piece without getting dirty.
Abstract:
A vacuum cleaner comprising a housing having an outer surface. A bumper strip projects outwardly from the housing and extends along the outer surface of the housing. A retaining element projects outwardly from the housing and extends along the outer surface of the housing adjacent the bumper strip. The retaining element overlaps the bumper strip. The bumper strip contacts the retaining element and is elastically deformable to slide with respect to the retaining element. The bumper strip forms a convex curved structure that bulges outwardly from the housing.

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.
Abstract:
A vacuum cleaner includes a housing and at least one running roller operatively connected to the housing. The roller has a hub, a running ring, a wall connecting the running ring and the hub. The wall has two side surfaces and a curved cross-section between the running ring and the hub. The roller has at least one reinforcing rib extending at least from one of the two side surfaces of the wall and being in contact with neither the hub nor the running ring in a non-loaded state of the running roller. The roller forms an elastic caster with a nave and a bearing race. The nave and the bearing race are connected to another by an S or Z-shaped curved wall. Ribs are provided for reinforcing the wall or the nave.

Abstract:
The invention relates to a stator (1) of an electrical machine (10), the electrical machine (10) itself, and a manufacturing method. The stator (1) has a meandering cooling channel (18), wherein the meandering cooling channel (18) is embedded in an element (22), wherein the element (22) comprises a material which is influenced thermally so as to form a shape of the element (22), wherein an iron-containing body (3), for guiding a magnetic field of the stator, is embedded in the element (22).
Abstract:
The invention relates to an electric machine which comprises a first machine part (30), comprising a stator element (31) and a rotor element (32) and being configured as a rotary actuator which interacts with a rotary movement of the rotor element (32). The electric machine (40) also comprises a second machine part (20), comprising a primary part (1) and a secondary part (2) and being configured as a linear actuator which interacts with a linear movement of the secondary part (2). The rotor element (32) of the first machine part (30) and the secondary part (2) of the second machine part (20) are interlinked. The secondary part (2) of the second machine part (20) can be rotated and is configured as an external rotor. Such a secondary part (2) allows to generate a higher power of a secondary machine part (20) acting as the linear motor. The secondary part (2) is mounted in the center thereof in relation to the primary part (1).
