Abstract

Disclosed is a cyclone-type dust collecting apparatus for a vacuum cleaner which is disposed in a dust collecting chamber connected with an air inlet path and an air discharge path of the cleaner for separating dusts and contaminants from air drawn in through a suction brush and then the air inlet path by a centrifugal force, the cyclone-dust collecting apparatus comprising a cylindrical cyclone body having an air inlet port and air discharge port respectively corresponding to the air inlet path and the air discharge path and fixed in an upper portion of the dust collecting chamber, a dirt-collecting receptacle removably disposed in a lower side of the cyclone body for collecting dusts and contaminants separated in the cyclone body by a centrifugal force, a filter assembly disposed in a lower part of the cyclone body and having a rotation filter rotated by air flow moving from the dirt-collecting receptacle to the air discharge port and preventing contaminants from flowing back, and a dusting member for automatically removing dusts on the rotation filter.

Claims

1. A cyclone-type dust collecting apparatus for a vacuum cleaner which is disposed in a dust collecting chamber connected with an air inlet path and an air discharge path of the cleaner for separating dusts and contaminants from air drawn in through a suction brush and then the air inlet path by a centrifugal force, the cyclone-dust collecting apparatus comprising:

a cylindrical cyclone body having an air inlet port and air discharge port respectively corresponding to the air inlet path and the air discharge path and fixed in an upper portion of the dust collecting chamber;

a dirt-collecting receptacle removably disposed in a lower side of the cyclone body for collecting dusts and contaminants separated in the cyclone body by a centrifugal force;

a filter assembly disposed in a lower part of the cyclone body and having a rotation filter rotated by air flow moving from the dirt-collecting receptacle to the air discharge port and preventing contaminants from flowing back; and

a dusting member for automatically removing dusts on the rotation filter.

2. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 1, wherein the filter assembly comprises:

a pipe member connected to a lower part of the cyclone body and formed to allow air to pass through;

a cover connected to an upper end of the pipe member and having an air hole; and

a shaft penetrating the pipe member, supporting the rotation filter and rotatably connected to the cover,

wherein the rotation filter is connected to a lower end of the pipe member and rotated by air flow while being supported by the shaft.

3. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 2, wherein the rotation filter comprises:

a turbine having a plurality of wings inserted into a lower end of the pipe member;

a filtering net on an outer circumferential surface of the turbine; and

a reverse prevention member connected to a lower end of the turbine and fixed to a lower end of the shaft for preventing contaminants from flowing back.

4. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 1, wherein the dusting member has one end fixed on an outer side of the filter assembly and the other end provided with a brush in contact with an outer surface of the rotation filter, and dusts are automatically brushed off by the brush when the rotation filter rotates.

5. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 4, wherein the dusting member is disposed in an oblique direction declining in a rotation direction of the rotation filter.

6. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 2, wherein the dusting member has one end fixed on an outer circumference of the pipe member and the other end provided with a brush in contact with the filtering net.

7. The cyclone-type dust collecting apparatus for a vacuum cleaner according to claim 6, wherein the dusting member is disposed in an oblique direction declining in a rotation direction of the turbine member.
