CYCLONE-TYPE DUST-COLLECTING APPARATUS FOR VACUUM CLEANER

摘要

A cyclone-type dust-collecting apparatus for a vacuum cleaner comprises a cyclone body, a dust-collecting receptacle; and a grill assembly. The cyclone body comprises an air inflow port and an air outflow port for forming an air vortex of dust-laden air drawn into the air inflow port. The dust-collecting receptacle is removably connected to th e cyclone body for separating dust and dirt from the dust-laden air by the air vortex. The grill assembly includes a first grill member, a second grill member, and a connection membe r. The grill assembly is disposed at the air outflow port of the cyclone body and prevent s the reverse flow of the dust and dirt into the air outflow port of the cyclone body. The firs t grill member has a supporter that is supported on the air outflow part of the cyclone body; a second grill member has a grill portion comprising a plurality of fine passage holes, through which the air flows to the air outflow port. These members are designed such that the firs t and second grill members are easily separable and connectable by a connection member, thereby to allow a user to easily remove the dirt collected in the grill portion of the second grill member by simply separating the second grill member from the connection member and washing the second grill member with water.
