The electric blower 2 is driven in a predetermined operation mode.

  Then, the floor brush 7 is moved back and forth on the floor surface, and dust on the floor surface is sucked together with air from the floor brush 7 and cleaned.

  The air sucked together with the dust from the floor brush 7 becomes a suction air, passes through the extension pipe 6 and the bent part 14 of the mounting cylinder part 5, passes through the valve element 55a from the upstream opening 55 of the dust collecting cup 21, and collects the dust. Flows into 48.

  Here, among the dust contained in the suction air, relatively small weight flows into the communication hole 51 together with the suction air without going straight in the dust collection chamber 48 and is collected by the first net filter 52. .

  On the other hand, dust that is relatively heavy among the dust contained in the suction air travels straight in the dust collection chamber 48, flows to the vent hole 53 together with the suction air, and is collected by the second net filter 54.

  At this time, in the dust collection chamber 48, dust adhering to the first net filter 52 is scraped off by the suction air that goes straight in the dust collection chamber 48 and is relatively collected in the dust collection chamber 48. Dust such as large cotton dust is compressed into the second net filter 54.

  The suction air in which dust is collected by the net filters 52 and 54 flows into the ventilation chamber 49, flows into the hose body 4 from the cylinder body 13, and then enters the dust collection chamber 11 from the body suction port 3. The fine dust that could not be collected by the dust collecting cup 21 is collected by the filter body in the main body dust collecting chamber 11 and flows into the electric blower 2.

  And the suction | inhalation wind which flowed into the electric blower 2 turns into exhaust air, and is exhausted to the exterior of the cleaner body 1 from the exhaust port which is not shown in figure.

  Further, when removing the dust collecting cup 21, when the operator pushes the clamp 61, the engaging portion 66 is detached from the engaged portion 23, and the dust collecting cup 21 can be removed. In this state, as shown in FIG. 4, when the operator pulls the dust collecting cup 21 upward and removes it, the shutter pieces 22a and 22b of the shutter 22 are urged by the springs 32a and 32b, respectively, and the accommodating portions 31a and 31b. The contact piece portions 34a and 34b come into airtight contact with each other via the packing 35, and the shutter 22 closes the mounting opening 16 as shown in FIGS. 3 and 5 (b).

  When cleaning with the dust collecting cup 21 removed, the operator grasps the mounting cylinder 5 and operates the hose side hand switch 26 to drive the electric blower 2 in a predetermined state. Clean as if 21 is installed.

  At this time, the dust sucked together with the air from the floor brush 7 flows into the main body dust collecting chamber 11 through the extension pipe 6, the mounting cylinder portion 5, the hose body 4 and the main body suction port 3. The dust is collected in the paper pack.

  When a predetermined amount or more of dust has accumulated in the dust collection chamber 48 of the dust collection cup 21, remove the dust collection cup 21 from the mounting opening 16, and push the bottom lid clamp 64 downward to remove the bottom lid 57. Open and discard the dust collected in the dust collection chamber 48 to the outside.

  Further, by providing the clamp 61 in the vicinity of the grip portion 42, the dust collection cup 21 can be attached to and detached from the mounting opening 16 while the grip portion 42 is gripped, so that the operability can be improved.

  Further, by providing each hand switch 26, 62 on both the grip part 42 and the mounting cylinder part 5, when the dust collecting cup 21 is attached to the mounting opening 16, the grip part 42 is gripped and the cup side hand switch The drive of the electric blower 2 can be operated at 62, and when the dust collecting cup 21 is removed, the drive of the electric blower 2 can be operated with the hose side hand switch 26, so that the usability can be improved.

  Then, by providing the clamp 61, the cup side hand switch 62, and the bottom lid clamp 64 in the vicinity of the grip portion 42, the dust collection cup 21 is attached, cleaned, the dust collection cup 21 is removed, and the dust collection cup 21 The operator can work with one hand all the way to the disposal of the dust inside, and the usability can be further improved.

  Further, since the dust collection cup 21 is positioned above the extension pipe 6 in the standing state of the extension pipe 6 that is housed in the vacuum cleaner, the dust collection cup 21 can be attached and detached without dusting the operator. The dust collected in the cup 21 can be discarded, and the usability is further improved, and the dust collecting cup 21 is positioned above the extension pipe 6 so that the air passage W can be removed when the dust collecting cup 21 is removed. It is also possible to prevent dust inside from spilling from the mounting opening 16.
