Abstract

Abstract A vacuum cleaner having a separation device and a vacuum source communicating with a tube handle. The tube handle is connected to a nozzle by a tube shaft (33). The tube shaft is either shaped as a cyclone separator or a cyclone separator is arranged between the nozzle and the tube handle. The cyclone separator is provided with a whirl chamber (37) which is defined, in part, by an up-side-down truncated cone (41). The whirl chamber has an inlet opening (38), a first outlet opening and a second outlet opening. The inlet opening is placed at the upper part of the whirl chamber (37). Partially cleaned air flows through the first outlet opening (39) which communicates with the vacuum source. The second outlet opening (42) is placed at the lower part of the whirl chamber. The second outlet opening communicates with a dust collecting container (43).

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).
