摘要： The invention relates to dirt separator module comprising a dirt-separation housing having an inlet and an outlet opening and defining a cyclonic airflow separator, and a suction source fluidly connected with the dirt-separation housing. A separator plate and a cylindrical wall of the dirt-separation housing form a toroidal cyclonic airflow chamber in the dirt-separator for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the cylindrical wall of the dirt-separation housing, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes dual cyclonic separators fluidly connected through a filter assembly. A further embodiment includes a cyclonic separator in the form of a tangential helical ramp.

摘要： A portable surface cleaning apparatus has a base for movement along a surface to be cleaned and an upright handle pivotally attached to a rearward portion of the base. A fluid dispensing nozzle for applying fluid to the surface and a suction nozzle for picking up fluid and debris from the surface are associated with the base. A clean water holding tank and a detergent holding tank are removably mounted to the handle while a recovery tank is removably mounted to the base. A mixing valve is fluidly connected between the holding tanks and the spray nozzle for changing the mixing ratio of the detergent with respect to the water. The fluid recovery tank includes an integrally molded conduit that extends from the suction nozzle and a mounting for an accessory hose that interrupts the fluid path from the suction nozzle in the conduit and redirects fluid flow through the hose. A pump is fluidly connected between the mixing valve and the dispensing nozzle and includes a pump priming valve that operates on negative air pressure to clear air from the fluid lines during pump operation. A free floating brush is pivotally attached to the base for automatically adjusting to different surface conditions during cleaning operations.

摘要： An arrangement for mounting a motor and fan unit to a support chassis within a vacuum cleaner housing includes a support structure defining an opening for receiving a first mounting portion on a back end of the motor and fan unit, a support member having a recessed portion for receiving a second mounting portion on a front end of the motor and fan unit and a flexible locking tab having an opening and being movable between engaging and disengaging positions relative to the motor and fan unit for receiving in the opening of the locking tab the second mounting portion on the front end of the motor and fan unit when the locking tab is in the engaging position. The mounting arrangement also includes a retaining structure which is movable between assembled and disassembled condition relative to the locking tab. The retaining structure includes a bracket which faces an outside face of the locking tab so as to block the movement of the locking tab from the engaging to the disengaging position when the retaining structure is in the assembled condition.

摘要： A portable surface cleaning apparatus has a base for movement along a surface to be cleaned and an upright handle pivotally attached to a rearward portion of the base. A fluid dispensing nozzle for applying fluid to the surface and a suction nozzle for picking up fluid and debris from the surface are associated with the base. Supply tanks are removably mounted to the handle or base while a recovery tank is removably mounted to the handle or base. An outlet in each supply tank includes a valve to close the outlet when the supply tank is removed from the base. A protrusion in a bottom surface of the supply tank defines a measuring volume for concentrated cleaning solution and is further adapted to stabilize the supply tank in the base or handle. The supply tank also includes an aperture through a lower portion selectively closed by a drain plug. A conduit connecting each supply tank to a dispensing nozzle includes a check valve restricting fluid flow to a direction from the tank and to the nozzle. Also, a float assembly in the recovery tank includes a first end for covering an air exit from the recovery tank and a second end, which is buoyant and elevated by the rising recovered fluid in the tank, for raising the first end to cover the air exit.

摘要： A convertible vacuum cleaner operable in both on-the-floor and above-the-floor cleaning operations is shown. Depending upon the location of the handle which is pivotally supported by the vacuum foot, a conversion valve interconnected to the handle automatically converts the vacuum between on-the-floor and above-the-floor cleaning operations. The conversion valve includes a flapper valve member which is actuated between a first position blocking fluid communication between the vacuum motor and the brush roll chamber and a second position blocking fluid communication between the vacuum motor and the accessory hose. The valve member is actuated between these two positions by a pin and actuator arm provided on the pivotally mounted valve member. The pin is received in a contoured groove formed on the motor housing and the motor housing is securely mounted to the handle and pivotally mounted with respect to the foot and valve member. As the handle is tilted between the substantially upright position and a tilted position, the flapper valve member is actuated between the first and second positions.

摘要： A vacuum cleaner is provided with a wheel housing having at least one axle bracket extending therefrom along a transverse axis and at least one axle bracket-receiving socket formed in a foot of the vacuum cleaner whereby the socket slidably receives and pivotally mounts the at least one axle bracket. The wheel housing is thereby pivotally mounted to the foot. A height adjustment mechanism is provided with the wheel housing having an actuator having a bearing shaft and a bearing sleeve with a longitudinal bore. The longitudinal bore of the bearing sleeve receives the bearing shaft to rotatably mount the actuator. A detent mechanism is provided between the bearing shaft and the bearing sleeve to releasably mount the actuator to the foot. The actuator can be adapted to release upon encountering abnormal forces applied against the vacuum cleaner.
