Improvements in vacuum cleaners
摘要:
A vacuum suction cleaning appliance has a casing (1) which accommodates one or more cyclone units, a motor driven fan unit for generating air-flow from a dirty air inlet tract (11) through said cyclone unit(s), a ground engaging cleaning head (2 and 4) rotatably mounted in the casing (1), a pipe (6, 44 and 45) connectable to a suction tool, and an air-flow control device. The air-flow control device and the motor driven fan unit are located within the lower end (7) of the casing (1). The air-flow control device is adapted to selectively direct dirt laden air into the dirty air inlet tract (11), from either the ground engaging cleaning head (2 and 4) or the suction tool via the pipe (6, 44 and 45), said air-flow control device being operated by rotation of the cleaning head (2 and 4) relative to the casing (1).
