Abstract:
A compact motor housing for housing a motor and a blower of a cleaning device and with integrated air outlet silencing. The motor housing encloses a flow passage between a flow inlet and outlet. The housing has a blower chamber fluidically connected to the flow inlet, and via first and second outlet openings also fluidically connected to at least two parallel, preferably similar, silencer ducts each being arranged in an area limited by an angle of less than 90°, seen in a view parallel with the blower and motor axis. The silencer ducts each have at least one wallbetween the blower chamber and the external wall of the motor housing for causing at least one flow direction bend, so as to provide a noise attenuating effect. The areas occupied by the at least two silencer ducts are non-overlapping, seen in a view parallel with the blower and motor axis. With a circular blower chamber, a compact box shaped motor housing can be provided with corner volumes available for silencer ducts.

Abstract:
A vacuum cleaner comprising a dirt-separation stage and a vacuum motor for moving air through the dirt-separation stage. The vacuum motor comprises an impeller driven by an electric motor. The impeller is then located upstream of the dirt-separation stage, the electric motor is located downstream of the dirt-separation stage, and at least part of the air discharged from the dirt-separation stage is used to cool the electric motor.
Abstract:
A surface treatment apparatus may include an air flow path extending from a dirty air inlet to a clean air outlet and a main body. A suction motor may be provided in the air flow path. A cyclone bin assembly may be provided in the air flow path and may be removably mountable to the main body. A pre-motor filter chamber may be provided and may have a rear wall, a sidewall extending and an openable front wall opposite the rear wall and sealingly enclosing the pre-motor filter chamber. The pre-motor filter chamber may be disposed longitudinally between the cyclone bin assembly and the suction motor and the cyclone bin assembly may be positioned in front of at least a portion of the openable front wall of the pre-motor filter chamber. The front wall may be accessible when the cyclone bin assembly is removed from the main body.

Abstract:
The present invention relates to a cleaning appliance (1) of the cylinder type. The cleaning appliance comprises a separating apparatus (4) for separating dirt from a dirt- bearing fluid flow, and a floor-engaging rolling assembly (6). The separating apparatus comprises a first cyclonic separation unit having a low efficiency cyclone and a second cyclonic separation unit having a plurality of second cyclones (84). The rolling assembly comprises a main body (8) having a recess (18) in which the separating apparatus (4) is received, and a plurality of floor-engaging wheels (10, 12) rotatably connected to the main body (8). The recess (18) in the main body comprises a plurality of shaped recesses (36), each of which corresponds to the shape of at least a portion of a second cyclone (84). When the separating apparatus (4) is received in the recess (18), a second cyclone (84) is located at least partially in each shaped recess (36).
