Grill assembly for a cyclone-type dust collecting apparatus for a vacuum cleaner
View Patent ↗A grill assembly for a cyclone-type dust collecting apparatus has a grill member having a grill supporting portion supported on the air outlet, a conical grill and a cylindrical grill portion, preferably integrally formed with each other. The dust blocking member has a connection member inserted and connected through the air passage hole of the cylindrical grill portion, and has a plurality of holes partitioned by a rib and interconnected with the air passage hole; and a dust blocking plate integrally formed with the connection member that is spaced from the connection member, air is discharged through the air passage hole extending through the lower portion of the grill assembly, and dust and foreign substances particularly adhere around the air passage hole.
1. A grill assembly for a cyclone-type dust collecting apparatus for a vacuum cleaner, the grill assembly being disposed in an air outlet of a cyclone body for separating dust and foreign substances from contaminant-laden air, the grill assembly comprising:
a grill member having an air passage hole extending through a lower grill portiong grill supporting portion supported on the air outlet, a conical grill and a cylindrical grill portion, all of which are integrally formed with each other, and the cylindrical grill portion further having an air passage hole extending through a lower grill portion thereof;
a dust blocking member removably mounted on the grill assembly through the air passage hole of the grill member; and
fixing means for removably fixing the dust blocking member with respect to the grill member.
2. The grill assembly of claim 1 , wherein the dust blocking member further comprises:
a connection member inserted and connected to the cylindrical grill portion through the air passage hole of the cylindrical grill portion, and having a plurality of holes that are partitioned by a rib and interconnected with the air passage hole; and
a dust blocking plate integrally formed with the connection member at a lower portion of the connection member, the dust blocking plate being spaced from the connection member by a predetermined distance.
3. The grill assembly of claim 2 , wherein the fixing means further comprises:
a fixing groove portion having a pair of guiding grooves formed to be substantially opposite to each other in an inner circumference of the cylindrical grill portion, and a pair of fixing grooves extending from leading ends of the guiding grooves in a radial direction of the cylindrical grill portion and in opposite directions from each other; and
a fixing protrusion portion formed on an outer circumference of the connection member to mate with the guiding grooves and the fixing grooves of the fixing groove portion.
4. The grill assembly of claim 1 , wherein the grill member further comprises:
a conical grill portion;
a first cylindrical grill portion of a predetermined diameter; and
a second cylindrical grill portion of a diameter larger than the diameter of the first cylindrical grill portion, the conical grill portion, the first cylindrical grill portion and the second cylindrical grill portion being integrally formed on the grill supporting portion that is supported on an air outlet, and the second cylindrical grill portion having an air passage hole extending through a lower portion.
5. The grill assembly of claim 4 , wherein the dust blocking member further comprises:
a connection member inserted in and connected through the air passage hole of the second cylindrical grill portion, and having a plurality of holes that are portioned by a rib and interconnected with the air passage hole; and
a dust blocking plate integrally formed with the connection member and located at a lower portion of the connection member, the dust blocking plate spaced from the connection member by a predetermined distance.
6. The grill assembly of claim 5 , wherein the fixing means further comprises:
a fixing groove portion having a pair of grooves formed to be substantially opposite to each other in an inner circumference of the second cylindrical grill portion, and a pair of fixing grooves extending from leading ends of the guiding grooves in a radical direction of the second cylindrical grill portion and in opposite directions from each other; and
a fixing protrusion portion formed on an outer circumference of the connection member to mate with the guiding grooves and the fixing grooves of the fixing groove portion.
