Abstract
Abstract A domestic vacuum cleaner is disclosed including a cyclone separator for separating household dust and debris from air. The cyclone separator includes a container 1 for collecting dust and debris at the lower end 42 thereof, an inlet 51 for introducing a fluid mixture swirling about an axis at a region of the container remote from the lower end 42, barrier means (11, 13a, 13b, 14a, 14b, 15a, 15b and 24) between the region and the lower end 42, and an outlet 52 for lighter phase of the mixture, the outlet opening from the region mentioned above. A lower portion of the container 1 is dividable from an upper portion to allow emptying of the container of collected dust and debris, the lower portion being below the barrier means (11, 13a, 13b, 14a, 14b, 15a, 15b and 24). <IMAGE>

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
131 words
A domestic vacuum cleaner including a cyclone separator
for separating household dust and debris from air, including
a container (1) for collecting dust and debris at a lower end
(42) thereof, means (51) for introducing a fluid mixture
swirling about an axis at a region of the container remote
from said lower end (42), barrier means (11, 13a, 13b, 14a,
14b, 15a, 15b and 24) between said region and said lower end
(42), and an outlet (52) for lighter phase of the mixture,
the outlet opening from said region, wherein a lower portion
of the container (1) is dividable from an upper portion to
allow emptying of the container of collected dust and debris,
said lower portion being below said barrier means (11, 13a,
13b, 14a, 14b, 15a, 15b and 24)
Claim 2
Dependent Claim
33 words
A domestic vacuum cleaner according to claim 1,
wherein the barrier means (11, 13a, 13b, 14a, 14b, 15a, 15b
and 24) has a solid outer perimeter which is continuous in
said axial direction.
Claim 3
Dependent Claim
48 words
A domestic vacuum cleaner according to claims 1 or 2,
wherein said barrier means (11, 13a, 13b, 14a, 14b, 15a, 15b
and 24) is mounted on a member (45) mounted centrally within
the container (1), the member (45) being closed off from
fluid communication with the container (1).
Claim 4
Dependent Claim
18 words
A domestic vacuum cleaner as claimed in claim 3, wherein
said member (45) extends throughout the container (1).
Claim 5
Dependent Claim
35 words
A domestic vacuum cleaner as claimed in claim 3 or 4,
wherein said member (45) is hollow and is connected to
receive relatively heavier phase components from a further
separator connected to said outlet (52).
Claim 6
Dependent Claim
25 words
A domestic vacuum cleaner according to any one of claims
1 to 5, comprising further barrier means (30, 34) extending
generally in said axial direction.
Claim 7
Dependent Claim
33 words
A domestic vacuum cleaner according to claim 6, wherein
the axial extent of said further barrier means (30, 34) is at
least 10% of the diameter of the container at its closed end.
Claim 8
Dependent Claim
36 words
A domestic vacuum cleaner according to claim 6 or 7,
wherein said further barrier means (30, 34) comprises two or
more spaced apart walls, the walls being spaced apart from an
edge of the container (1).
Claim 9
Dependent Claim
42 words
A domestic vacuum cleaner according to any one of the
preceding claims, wherein the gap between the wall of the
container (1) and the outer barrier is between 5 and 25% of
the diameter of the container (1) at its closed end.
Claim 10
Dependent Claim
44 words
A domestic vacuum cleaner comprising a reverse flow
cyclone according to any one of claims 3 to 9, wherein the
member (45) has a radius no more than 50% of the radius of
the container (1, 41), when the latter is of circular cross-section.
Claim 11
Dependent Claim
47 words
A domestic vacuum cleaner according to any one of the
preceding claims, wherein a split between the lower portion
of the container (1, 41) and the upper portion is about a
plane below the barrier means (3, 11, 13a, 13b, 14a, 14b,
15a, 15b, 24 and 46).
Claim 12
Dependent Claim
54 words
A domestic vacuum cleaner according to any one of claims
1 to 10, wherein a split between the lower portion of the
container (1, 41) and the upper portion is about a plane at
the level of the bottom of the barrier means (3, 11, 13a,
13b, 14a, 14b, 15a, 15b, 24 and 46).
Claim 13
Dependent Claim
48 words
A domestic vacuum cleaner according to any one of claims
1 to 10, wherein a split between the lower portion of the
container (1, 41) and the upper portion is about a plane
