Cyclone-type dust collecting apparatus for vacuum cleaner
First Claim
1. A cyclone-type dust collecting apparatus for a vacuum cleaner, comprising:
- a cyclone body having an air inlet port and an air outlet port, for forming a vortex current of air which contains dust and is introduced through the air inlet portt;
a dust collecting container removably coupled to the cyclone body so as to collect the dust separated by a centrifugal force of the vortex current in the cyclone body;
a double grill assembly disposed at an upstream portion of the air outlet port in the cyclone body to prevent dust separated from the air from flowing back through the air outlet port, and having a dual structure comprising an outer grill and an inner grill; and
a fine dust collecting means disposed at a downstream portion of the double grill assembly in the cyclone body to collect fine dust which is not removed by the double grill assembly.

15. A vacuum cleaner, comprising:
-
a suction brush having a nozzle opened toward an surface to be cleaned and a motor driving chamber in which a motor for generating a suction force in the nozzle is mounted; a main body of the vacuum cleaner, which is rotatably connected to the suction brush and has an air outlet path and an air inlet path connected to the motor driving chamber; and a cyclone-type dust collecting apparatus removably disposed in a dust chamber of the main body, for separately collecting dust contained in air introduced through the nozzle of the suction brush, wherein the cyclone-type dust collecting apparatus comprises a cyclone body having an air inlet port connected to the air inlet path and an air outlet port connected to the air outlet path and forming a vortex current of the air containing the dust introduced through the air inlet port;
a dust collecting container removably coupled to the cyclone body so as to collect the dust separated by centrifugal force of the vortex current in the cyclone body;
a double grill assembly disposed at an upstream portion of the air outlet port in the cyclone body to prevent dust separated from the air from flowing back through the air outlet port, and having a dual structure comprising an outer grill and an inner grill; and
a fine dust collecting means disposed at a downstream portion of the double grill assembly in the cyclone body to collect fine dust which is not removed by the double grill assembly. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
