  In the vacuum cleaner having the above-described configuration, dust on the surface to be cleaned is sucked together with air from the suction port body by driving the electric blower. The air sucked from the suction port body flows into the dust collecting container of the dust collecting portion from the inlet through the extension pipe and the connecting hose. The air flowing into the dust collecting container swirls in the dust collecting container, and large dust is separated by the centrifugal force and accumulated in the dust collecting container.

  The airflow from which large dust has been removed flows through the inner cylinder through the outlet, and fine dust is collected by the filter. The airflow from which fine dust has been removed flows through the communication path, and flows out of the dust collector through the dust collector exhaust port. The air that flows out from the dust collecting section passes through the electric blower and is exhausted to the outside. Thereby, the surface to be cleaned can be cleaned.

  When the dust collecting part is detached from the main body part and the filter holding part is detached from the dust collecting container together with the cover part, the dust accumulated in the dust collecting container can be discarded. Moreover, the filter can be cleaned by removing the cover from the filter holding part.

  In FIG. 10, the annular portion 50 a of the filter holding portion 50 is provided with a contact portion 54 and a lock member 52 at a front portion opposed to the hinge portion 60 in the radial direction. The abutting portion 54 abuts on the pressing member 45 and is pressed by the urging force of the pressing member 45. The lock member 52 is movably provided in the circumferential direction and is urged in one direction (the direction of the arrow E1) by a compression spring (not shown). The lock member 52 engages with the hook 46 to lock the closed state of the cover unit 40 and the filter holding unit 50.

  When the lock member 52 is moved in the other direction (arrow E2 direction) against the urging force, the engagement between the lock member 52 and the hook 46 is released. Thereby, the closed state of the cover part 40 and the filter holding | maintenance part 50 is cancelled | released. At this time, the pressing member 45 presses the contact portion 54 by the urging force of a compression spring (not shown), and the front portion of the cover portion 40 pops up and is lifted by a predetermined amount. Thereby, the cover part 40 can be easily opened by gripping the grip part 41 (see FIG. 3) and the front part of the cover part 40.

  The filter holding unit 50 is provided with a dust removing device 30 that removes the filter 37.

  When the cover portion 40 is opened, the handle 34 is exposed. When the rotating body 31 is rotated by holding the handle 34, the filter 37 is hit by the dust removing member 33. Thereby, the dust collected by the filter 37 falls into the dust collecting container 22 and the filter 37 can be removed.

  In the vacuum cleaner 1 having the above configuration, the dust on the floor surface is sucked from the suction port body 5 by driving the electric blower 6 and flows through the extension pipe 4 and the connection hose 3. The air flow including dust flows into the dust collecting container 22 of the dust collecting unit 20 through the connection port 10a and the inflow port 22a, and forms a swirling air flow in the dust collecting container 22. The relatively large dust contained in the airflow is removed by the centrifugal force of the swirling airflow, and is accumulated in the dust collecting container 22.

  The airflow from which the large dust has been removed flows out from the outlet 51 a into the inner cylinder 51 and rises, and fine dust is collected by the filter 37. The airflow that has passed through the filter 37 flows out of the dust collector 20 through the dust collector exhaust port 42a. The airflow flowing out from the dust collecting unit 20 flows through the duct 15 and is exhausted from the exhaust port 10b through the electric blower 6.

  When the grip portion 41 is pulled up, the engagement between the engagement portion 43 and the main body cover 10 is released, and the dust collection portion 20 is detached from the dust collection chamber 19. When the filter holding unit 50 is detached from the dust collecting container 22 together with the cover unit 40 by the rotation of the clip 23, the dust in the dust collecting container 22 is discarded. When the cover 40 is opened by operating the lock member 52, the dust removal device 30 can remove the filter 37, wash the filter 37 with water, and the like.

  According to this embodiment, the cover part 40 is pivotally supported by the filter holding body 50 by the hinge part 60, and the first axial part 61 and the second axial part 62 that are separated from each other in the circumferential direction by the hinge part 60 and the first axis. It has the 1st bearing part 71 and the 2nd bearing part 72 which support the part 61 and the 2nd axial part 62, respectively. Thereby, the cover part 40 can be opened by rotation and the filter 37 can be cleaned. For this reason, when the cleaning of the filter 37 is completed, the mounting work of the cover part 37 can be omitted.

  Further, the first and second shaft portions 61 and 62 can pivotally support the cover portion 40 in a wide range in the circumferential direction, and can reduce the bending of the pivotal shaft as compared with a single pivot shaft. Thereby, the stability at the time of opening and closing of the cover part 40 can be improved. In addition, the hinge part 60 can be disposed close to the peripheral surface of the filter holding part 50 having a substantially circular shape in plan view. Thereby, size reduction of the dust collection part 20 attached or detached with respect to the main-body part 2 can be achieved, and the burden at the time of conveyance of the dust collection part 20 by discard of dust etc. can be reduced. Therefore, the convenience of the vacuum cleaner 1 can be improved.

  Further, a dust collecting portion exhaust port 42a (exhaust port) of the communication passage 42 is opened on the back surface of the cover portion 40, and a hinge portion 60 is formed on the back surface of the cover portion 40 and is disposed in front of the dust collecting portion exhaust port 42a. Therefore, the dust collection part 20 can be easily attached or detached from the upper part of the main body part 2.

  In addition, since the clip 23 that engages and disengages the dust collecting container 22 and the filter holding unit 50 is disposed between the first shaft portion 61 and the second shaft portion 62, the first and second shaft portions 61 and 62 are separated from each other. The dust collection unit 20 can be further downsized by effectively using the space. Note that the clip 23 may be provided on the filter holding unit 50 to be engaged with and disengaged from the dust collecting container 22.

  The first bearing portion 71 has fitting portions 71a and 71b to which the first shaft portion 61 is fitted at both ends in the axial direction, and the fitting portions 71a and 71b have an open portion 71c in a part of the circumferential surface. It is formed in a C-shaped cross section. In addition, an engaging claw 71e of an elastic body that engages with the first shaft portion 61 is provided between both the fitting portions 71a and 71b.

  Similarly, the 2nd bearing part 72 has fitting part 72a, 72b which the 2nd axial part 62 fits in the both ends of an axial direction, and fitting part 72a, 72b has the open part 72c in a part of surrounding surface. It has a C-shaped cross section. In addition, an engaging claw 72e of an elastic body that engages with the second shaft portion 62 is provided between both the fitting portions 72a and 72b. Accordingly, it is possible to easily prevent the first shaft portion 61 and the second shaft portion 62 from falling off by the engagement of the engaging claws 71e and 72e.

  Further, since the opposing wall surfaces 71d and 72d (72d not shown) of the opening portions 71c and 72c extend obliquely upward from the contact points with the first shaft portion 61 and the second shaft portion 62, the cover portion 40 is opened. Dropout can be prevented more reliably.

  Further, a dust removing member 33 for removing dust by hitting the filter 37 by operating the handle 34 is provided, and is exposed when the handle 34 opens the cover portion 40.
