Abstract: A dust cleaner includes a primary cyclone part formed by an outer case and an inner case; and a secondary cyclone part including a set of cyclones. The secondary cyclone part includes a casing member mounted on the inner case and configured to form casings of the cyclones arranged around a hollow part; and vortex finders provided inside the casings and including guide vanes extending in a spiral direction and forming a revolving flow at outer circumferential surfaces. The casing member forms inlet flow paths of the cyclones, and each of the inlet flow paths is formed in a direction inclined with respect to a direction toward a center of each of the vortex finders to enable air to flow in a direction eccentric from the center of each of the vortex finders.

Abstract: A dust collector includes a primary cyclone unit to separate dust from air introduced from outside dust collector and a secondary cyclone unit includes axial cyclones which separate fine dust from air introduced in an axial direction. The secondary cyclone unit includes a first group of axial cyclones disposed along a circumference of a first circle so as to contact an inner circumferential surface of an inner case, and formed to be partially spaced apart from the inner circumferential surface of the inner case to form first passages therebetween; and a second group of axial cyclones disposed to contact each other along a circumference of a second circle concentric with the first circle and smaller than the first circle, and formed to contact some of the first group of axial cyclones and to be spaced apart from others of the first group axial cyclones to form second passages therebetween.

Abstract: The present disclosure relates to a cleaner which includes: a dustbin having a slit formed on one side thereof; a compression lever housing disposed on an outside of the slit and mounted to the dustbin; a compression plate disposed on an inside of the dustbin and configured to ascend in a direction in which the slit extends; and a sealer disposed in the compression lever housing, coming in close contact with the slit, and extending along the slit. Therefore, the cleaner according to the present disclosure may prevent a problem that is likely to occur during an operation of the compression lever assembly because of trapped dust, and can be maintained in a cleaner state as the user may easily separate the cleaner by assemblies to sterilize the parts.

Abstract: The present disclosure relates to a cleaner including: a cyclone part of which one side has an inlet formed therein and the other side has an outlet formed therein; a housing which is connected to the cyclone part; a motor unit which is disposed in the housing, of which one side has a suction inlet formed therein that sucks air from the cyclone part, and of which the other side has a discharge port formed therein that discharges the air to the outside; and a filter which is disposed in the housing, of which one side covers the outlet of the cyclone part, and of which the other side covers the suction inlet of the motor unit. The filter includes: a first surface extending from a front to a left rear thereof; and a second surface extending from a front to a right rear thereof. Accordingly, it is possible to reduce pressure loss of the air that has passed through the filter, and a filtration performance can be obtained. Also, dust bins of various sizes can be variably installed.
