Abstract
A dust separating apparatus for a vacuum cleaner includes a dust collection casing with an air inlet at a lower portion, a mesh filter formed on a bottom surface of the dust collection casing to firstly filter the contaminant from the drawn-in air, a plurality of cyclones formed in parallel in the dust collection casing to secondly filter the contaminant in the air drawn in via the air inlet, and a dust collection part formed at one side of the plurality of cyclones to collect the contaminant separated from the air. The air flowed in the air inlet formed at the lower portion of the dust collection casing is sequentially discharged via the mesh filter formed on the bottom surface of the dust collection casing and the plurality of cyclones.
Claims9
A dust separating apparatus detachably engaged with a mounting chamber of a vacuum cleaner body to separate and collect a contaminant from an air drawn in from a cleaning surface by a suction force of a motor, comprising:
- a dust collection casing with an air inlet at a lower portion;
- a mesh filter formed on a bottom surface of the dust collection casing to filter the contaminant from the drawn-in air;
- a plurality of cyclones formed in parallel in the dust collection casing to secondly filter the contaminant in the drawn-in air;
- and
- a dust collection part formed at one side of the plurality of cyclones to collect the contaminant separated from the drawn-in air,
- wherein, if the mesh filter is unclogged, the drawn-in air comprises a first portion that is discharged via the mesh filter and a remaining portion that is discharged via the plurality of cyclones, and wherein, if the mesh filter is clogged, all the drawn-in air is discharged via the plurality of cyclones.
A dust separating apparatus detachably engaged with a mounting chamber of a vacuum cleaner body to separate and collect a contaminant from an air drawn in from a cleaning surface by a suction force of a motor, comprising:
- a dust collection casing with an air inlet at a lower portion and being substantially semicircular to correspond to a shape of the mounting chamber;
- a guide air path guiding the drawn-in air and contaminant to directly discharge to the motor, the guide air path having a mesh filter filtering the contaminant from a first portion of the drawn-in air when the mesh filter is unclogged;
- a primary cyclone and a secondary cyclone formed in parallel with one another in the dust collection casing, the primary and secondary cyclones filtering the contaminant from a second portion of the drawn-in air when the mesh filter is unclogged but filtering the contaminant from all of the drawn-in air when the mesh filter is clogged, and discharging the drawn-in air removed of the contaminant to the motor;
- a dust collection part formed at one side of the primary and the secondary cyclones in the dust collection casing to collect the contaminant separated from the air by the primary and the secondary cyclones;
- and
- a cover detachably engaged with a top portion of the dust collection casing and having a discharge guide pipe.
