Abstract
A dust separator of a cyclone type cleaner includes a first dust separator connected to a suction pipe, for separating dust from air by a centrifugal force for the first time; a collecting container connected to a lower portion of the first dust separator and in which the dust separated in the first dust separator is collected; and a second dust separator connected to an upper portion of the first dust separator, for sucking air which has passed through the dust separation in the first dust separator and separating dust from the air by a centrifugal force for the second time, so that an efficiency of collecting dust is improved without deteriorating a suction force of air.
Claims8
A dust separator of a cyclone type cleaner comprising:
- a first dust separator connected to a suction pipe, for separating dust from air by a centrifugal force for the first time;
- a collecting container connected to a lower portion of the first dust separator and in which the dust separated in the first dust separator is collected;
- and
- a second dust separator connected to an upper portion of the first dust separator, for sucking air passed through the first dust separator and for separating dust from the air by a centrifugal force for the second time,
- wherein the second dust separator comprises:
- a dust separating container connected to the first dust separator by a connection pipe;
- and
- a circulation pipe connected to the dust separating container, for re-sucking the dust separated in the dust separating container into the first dust separator.
A cyclone type cleaner comprising:
- a cleaner main body having a blower generating a suction force for sucking dust;
- a suction head mounted at the cleaner main body and having a suction opening through which dust is sucked;
- and
- a dust separator connected to a suction pipe which is connected to the suction head, wherein the dust separator comprises:
- a first dust separator connected to a suction pipe, for separating dust from air by a centrifugal force for the first time;
- a collecting container connected to a lower portion of the first dust separator and in which the dust separated in the first dust separator is collected;
- and
- a second dust separator connected to an upper portion of the first dust separator, for sucking air passed though the first dust separator and for separating dust from the air by a centriftigal force for the second time,
- wherein the second dust separator comprises:
- a dust separating container connected to the first dust separator by a connection pipe;
- and
- a circulation pipe connected to the dust separating container, for re-sucking the dust separated in the dust separating container into the first dust separator.
