Abstract (en)
[origin: WO2007021144A1] Disclosed herein is an exhaust structure of a vacuum cleaner. The exhaust structure of the vacuum cleaner comprises a main body 10 having a suction port 12 and a discharge port 14 formed thereon, a suction fan 62 positioned inside the discharge port 14, a dust container 50 mounted at one side of a flow passage between the suction port 12 and the discharge port 14 and having a suction opening 52 and an exhaust opening 54 formed at one side thereof, and an exhaust conduit 82 extending between the exhaust opening 54 and the discharge port 14. The exhaust structure prevents reduction in vacuum force by air leakage resulting from inclination of a dust container towards one side, and permits reduction in use of a sealing material.
