[0087] figure 1 It is a vertical sectional view of the cyclone dust collector of the electric vacuum cleaner according to the first embodiment of the present invention. The cyclone dust collector 5 has at its upper portion a suction air guide 20 having an inlet 5a formed therethrough. The cyclonic dust collector 5 communicates with a connection pipe 3 which together with the suction air guide 20 forms a suction air channel. The cyclone dust collector 5 is cylindrical in shape and arranged substantially parallel to the connecting pipe 3 . The sucked air flows into the cyclonic dust collector 5 through the inlet 5a along a path substantially perpendicular to the path of the air discharged from the cyclonic dust collector 5 .
[0088] On the suction air guide 20, a connecting pipe 10b communicating with the connecting piece 10 (see FIG. 50) is formed so as to protrude approximately from the center of the top surface of the cyclone dust collector 5. A holding portion 20a is als...

[0115] Figure 16 and 17 It is a perspective view and a vertical sectional view of the cyclone dust collector and its surroundings of the electric vacuum cleaner of the second embodiment of the present invention, respectively. In this embodiment, the suction air guide 20 and the connecting pipe 3 are integrated, which leads to a better appearance and more user-friendliness.
[0116] Figure 18 is along Figure 17 Horizontal section taken along line XVIII-XVIII shown in . On the side of the suction air guide 20 of the connecting pipe 3 , a dust collection chamber mounting portion 3 a is formed along the length of the connecting pipe 3 . The first and second dust collection chambers 7 and 8 are mounted on the dust collection chamber mounting portion 3a. At the lower portion of the dust collection chamber mounting portion 3a, a slit 31 is formed, and a slider 16 is fitted into the slit. The slider 16 can slide along the slit 31 in the vertical direction (in the direction in...

[0126] A third embodiment of the present invention will be described below. Figure 21 is a vertical sectional view of the cyclone dust collector 5 of the cyclone type electric vacuum cleaner of this embodiment. In this embodiment, an adapter pipe 29 is integrally formed with the suction air guide 20, and the connection pipe 3 is fitted to the lower end of the adapter pipe 29. As shown in FIG. On this adapter pipe 29 and on the second dust collection chamber 8 is arranged a mounting mechanism as described in the second exemplary embodiment.
[0127] An exhaust pipe 15 is inserted into the connecting pipe 10b and fixed thereto with screws (not shown). A spacer 7c is fitted to the lower end of the connecting pipe 10b. Above the air port 11a and the filter 11b of the exhaust pipe 15, a flange 88 is provided perpendicular to the axial direction so that the top surface of the flange 88 is kept in close contact with the gasket 7c.
