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 intersecting the barrier means (3, 11, 13a, 13b, 14a, 14b, 15a, 15b, 24 and 46).
Claim 14
Dependent Claim 38 words
A domestic vacuum cleaner according to any one of the preceding claims, and wherein the axial length of a shroud is between 50% and 150% of the outer diameter of the outlet for lighter phase of the mixture.
Claim 15
Dependent Claim 24 words
A domestic vacuum cleaner according to claim 14, wherein the shroud has a clear area of between 30% and 70% of its surface area.
Claim 16
Independent Claim 35 words
A method of separating gases, liquids or solids of different density, or combinations thereof, comprising introducing them as a swirling mixture to the domestic vacuum cleaner according to any one of claims 1 to 16.
