Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A vacuum cleaner comprising a cyclone separator, a
vacuum source (11) communicating with a tube handle (14), said
tube handle being connected to a nozzle (16) by means of a tube
shaft (15, 33), the tube handle (14) communicating with a
cyclone separator, characterized in that said cyclone separator
includes a whirl chamber (24, 37) which is at least partially
defined by an up-side-down truncated cone (18b, 41), said
cyclone separator comprising: an inlet opening (23, 38), said inlet opening being
located at an upper part of the whirl chamber (24, 37); a central first outlet opening (31, 39) for partially-cleaned
air, said first outlet opening communicating with the
vacuum source; a second outlet opening (22, 42) for separated particles
disposed at a lower part of the whirl chamber, said second
outlet opening communicating with a dust collecting container
(26, 43).
Claim 2
Dependent Claim
145 words
Vacuum cleaner according to claim 1, characterized in that the cyclone separator is enclosed in a shell (34)
comprising an upper part (34a) with a first tube coupling (35)
and a second tube coupling (40), said first tube coupling being
connected to the tube shaft (33) and said second tube coupling
(40) being connected to the tube handle (14), said upper part
(34a) having a channel (36) connecting said first tube coupling
(35) with the whirl chamber (37) and a mainly cylindrical wall
part which is provided with the inlet opening (38), said inlet
opening being arranged such that the air flows mainly
tangentially into the whirl chamber, said first outlet opening
(39) being provided by a sleeve, said sleeve having an axis
which is generally parallel to the axis of the cylindrical wall
part, said sleeve being connected to the second tube coupling
(40).
Claim 3
Dependent Claim
118 words
Vacuum cleaner according to claim 1, characterized in that
the tube shaft (15) comprises the whirl chamber (24), said
whirl chamber having a mainly cylindrical wall part (17)
provided with said inlet opening (23) through which air flows
mainly tangentially into the whirl chamber, the inlet opening
(23) communicating with a connecting tube disposed at the lower
part of the tube shaft via a channel (19, 28), said first
outlet opening (31) being designed as a sleeve, said sleeve
having an axis which is generally parallel to an axis of the
cylindrical wall part, said sleeve communicating with a tube
connection (32) for the tube handle (14), and the tube shaft
(15) enclosing said up-side-down truncated cone (18b).
Claim 4
Dependent Claim
26 words
Vacuum cleaner according to any of the preceding claims, characterized in that the tube handle (14) is connected to the
vacuum source via a hose (13).
Claim 5
Dependent Claim
23 words
Vacuum cleaner according to any of claims 1 - 3, characterized in that the vacuum source is integrated into the
tube handle (14).
