Abstract
Abstract A cyclone-type dust-collecting apparatus for use in a vacuum cleaner has a cyclone body having an inflow port and an outflow port, the cyclone body being capable of forming a whirling air current from dust-laden air drawn into the vacuum cleaner through the inflow port; a dust-collecting chamber being removably connected with the cyclone body, for collecting dust separated from the drawn air in the whirling air current; and a grill assembly disposed at the outflow port of the cyclone body for preventing a reverse flow of dust through the outflow port of the cyclone body. The grill assembly has a first grill member having a supporting portion supported on the outflow port of the cyclone body; a second grill member removably connected to a lower opening of the first grill member; and a grill portion provided to define a passage in fluid communication with the outflow port in an outer circumference of the second grill member.

Claim 1
Independent Claim
160 words
A cyclone dust-collecting apparatus for use in a vacuum cleaner, comprising: a cyclone body having an inflow port and an outflow port, the cyclone body being capable of forming a whirling air current from dust-laden air drawn into the vacuum cleaner through the inflow port; a dust-collecting chamber removably connected with the cyclone body, for collecting dust separated from the drawn air in the whirling air current; and a grill assembly disposed at the outflow port of the cyclone body for preventing reverse flow of dust through the outflow port of the cyclone body, the grill assembly comprising: a first grill member having a supporting portion supported on the outflow port of the cyclone body; a second grill member removably connected to a lower opening of the first grill member and having an outer circumference; and a grill portion provided to define a passage in fluid communication with the outflow port in the outer circumference of the second grill member.
Claim 2
Dependent Claim
160 words
A cyclone dust-collecting apparatus for use in a vacuum cleaner, comprising: a cyclone body having an inflow port and an outflow port, the cyclone body being capable of forming a whirling air current from dust-laden air drawn into the vacuum cleaner through the inflow port; a dust-collecting chamber removably connected with the cyclone body, for collecting dust separated from the drawn air in the whirling air current; and a grill assembly disposed at the outflow port of the cyclone body for preventing reverse flow of dust through the outflow port of the cyclone body, the grill assembly comprising: a first grill member having a supporting portion supported on the outflow port of the cyclone body; a second grill member removably connected to a lower opening of the first grill member and having an outer circumference; and a grill portion provided to define a passage in fluid communication with the outflow port in the outer circumference of the second grill member.
Claim 3
Dependent Claim
49 words
The cyclone dust-collecting apparatus of claim 1 , wherein the first grill member further comprises a female-screw portion formed on an inner circumference of the lower opening, and the second grill member comprises a male-screw portion formed on an outer circumference of upper portion corresponding to the female-screw portion.
Claim 4
Dependent Claim
53 words
The cyclone dust-collecting apparatus of claim 1 , wherein the grill portion is formed by fitting a mesh filter in the second grill member, the mesh filter comprising a plurality of fine holes, and the second grill member comprising a plurality of window-shaped openings formed in the outer circumference in a radial direction.
Claim 5
Dependent Claim
57 words
The cyclone dust-collecting apparatus of claim 3 , wherein the mesh filter comprises: a filter frame comprising an upper ring, a lower ring, and two or more ribs connecting upper and lower rings; and a net insert-molded in the filter frame so as to be placed in the openings partitioned by the ribs of the filter frame.
Claim 6
Dependent Claim
54 words
The cyclone dust-collecting apparatus of claim 4 , wherein the lifter frame is formed of a plastic, and upper and lower rings of the filter frame are vapor-deposited onto a corresponding portion of the second grill member so that the filter frame is inserted in the second grill member, thereby constituting the mesh filter.
Claim 7
Dependent Claim
35 words
The cyclone dust-collecting apparatus of claim 4 , wherein the filter frame is formed of rubber and is retained in place by an interference-fit relative to the second gnu member, thereby constituting the mesh filter.
Claim 8
Dependent Claim
32 words
The cyclone dust-collecting apparatus of claim 1 , wherein the grill portion is formed by direct boring of a plurality of fine holes in the outer circumference of the second grill member.
Claim 9
Dependent Claim
45 words
The cyclone dust-collecting apparatus of claim 1 , wherein the grill assembly comprises a dust reverse flow preventing member disposed at the lower opening of the second grill member for deflecting the dust entrained in the upwardly directed air current of the dust collecting chamber.
Claim 10
Dependent Claim
73 words
The cyclone dust-collecting apparatus of claim 8 , wherein the dust reverse flow preventing member comprises: a cylinder press-fit through the lower opening of the second grill member, and comprising upper and lower supporting portions having two or more ribs; a shaft supported by upper and lower supporting portions; and a plate connected to an end of the shaft, disposed at a predetermined distance from a lower end of the second grill member.
Claim 11
Dependent Claim
26 words
The cyclone dust-collecting apparatus of claim 9 , wherein the cylinder comprises a spiral guide formed therein for guiding the flow of air being discharged therethrough.
Claim 12
Dependent Claim
16 words
The cyclone dust-collecting apparatus of claim 9 , wherein the cylinder and the plate comprise rubber.
Claim 13
Dependent Claim
16 words
The cyclone dust-collecting apparatus of claim 9 , the plate is formed in a conical shape.
Claim 14
Dependent Claim
34 words
The cyclone dust-collecting apparatus of claim 1 , wherein the cyclone body comprises a secondary handle protruding from an extension pipe of the vacuum cleaner to enable a user to grip the extension pipe.
Claim 15
Dependent Claim
50 words
The cyclone dust-collecting apparatus of claim 13 , wherein the cyclone body comprises upper and lower bodies which are separately formed and mate with each other, and the secondary handle comprises a pair of handle portions in symmetrical shape formed on upper and lower bodies and mated with each other.
Claim 16
Dependent Claim
56 words
The cyclone dust-collecting apparatus of claim 1 , wherein the cyclone body comprises a guiding surface formed at a sidewall of the inflow port, for guiding the flow of air drawn in through the inflow port and thereby improving a directionality of the drawn air, the guiding surface being formed at a predetermined radius of curvature.
Claim 17
Dependent Claim
32 words
The cyclone dust-collecting apparatus of claim 15 , wherein the radius of curvature of the guiding surface is smaller than the radius of curvature of the inner circumference of the cyclone body.
