发明名称 VACUUM CLEANER
摘要 PROBLEM TO BE SOLVED: To provide a vacuum cleaner removing dust adhering to a filter in an inexpensive constitution. SOLUTION: In this vacuum cleaner, an air current is generated by a motor-driven blower 5 provided in a vacuum cleaner body 2, the air current is sucked from a nozzle 3 and introduced into a cyclone cylinder 28 as a dust collecting chamber, and dust is separated from the air current by a main filter 38. A fan 34 provided with a claw 54 as an abutment part coming into contact with the main filter 38 is provided on the downstream side of the main filter 38. An air current passage 35 is provided for guiding the outside air to the fan 34 not through the main filter 38, and an opening and closing means 56 for optionally opening and closing the air current passage 35 is provided. Thus, the fan 34 is rotated by the air current introduced from the air current passage 35, and at this time, the dust adhering to the main filter 38 is shaked off by vibration generated by moving the claw 54 in contact with the main filter 38.
