#CMT# #/CMT# A cyclone separating apparatus comprises a first cyclone separating dust from dust-laden air, second cyclones centrifugally separating fine dust particles from air which is first separated at the first cyclone, and a dust-collecting unit detachably connected to the first and second cyclones and separately collecting large dust particles separated at the first cyclone and fine dust particles separated at the second cyclone. #CMT# : #/CMT# An independent claim is also included for a vacuum cleaner comprising a cleaner body drawing-in dust-laden air and generating a suction force, a suction brush fluidly connected to the cleaner body to draw-in dust from a cleaning surface using the suction force, and the above cyclone separating apparatus formed in the cleaner body. #CMT#USE : #/CMT# Used for separating dust from dust-laden air. #CMT#ADVANTAGE : #/CMT# The dust collecting efficiency is improved and the suction efficiency is not deteriorated, because large dust particles are separated first before separating fine dust particles. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure is a sectional view of the cyclone separating apparatus. 115 : First chamber 121 : First inlet 123 : First outlet 130 : Grill member 141 : Second inlet 143 : Second outlet 145 : Second chamber 161 : First cylindrical dust receptacle 163 : Second cylindrical dust receptacle 190 : Inflow and outflow cover 191 : Cyclone cover 193 : Top opening 197 : Air path 199 : Discharging path 280 : Second sealing member 290 : First sealing member #CMT#MECHANICAL ENGINEERING : #/CMT# Preferred Components: The first cyclone comprises a first chamber (115) centrifugally separating dust-laden air, a first inlet (121) formed at the first chamber to draw-in the dust-laden air, and a first outlet (123) formed at the first chamber to discharge air. The first cyclone is integrally formed with the second cyclones. The second cyclones are located on an outer circumference of first cyclone to enclose the first cyclone. Each second cyclone comprises a second chamber (145) centrifugally separating air which is first separated at the first cyclone, a second inlet (141) formed at the second chamber to draw-in air which is discharged from the first cyclone, and a second outlet (143) formed at the second chamber to discharge dust-separated air. Cyclone partitions are formed between the respective second cyclones. The first chamber is cylindrical, and the second chamber includes a predetermined part of one end of truncated conical shape. The dust-collecting unit comprises a first cylindrical dust receptacle (161) for collecting dust separated at the first cyclone, and a second cylindrical dust receptacle (163) for collecting dust separated at the second cyclone. The first and second dust receptacles have transparent or translucent part on their respective sidewalls. The first dust receptacle is disposed inside and is integrally formed with the second dust receptacle. It includes a first sealing member (290) at an upper part and hermetically connected to the first cyclone. The second dust receptacle includes a second sealing member (280) at an upper part and hermetically connected to the second cyclone, and a handle on the sidewall. The cyclone separating apparatus includes an inflow and outflow cover (190) formed at a top of the first and second cyclones and fluidly connecting the first and second cyclones, and a cyclone cover (191) formed over the inflow and outflow cover and including a cone shape that opens upwards and downwards. |
