For this reason, the brush holding portion 41 rotates between the cleaning position and the storage position with a small rotation angle of 90 ° or less without blocking the front of the air flow path 31b. Thereby, the outer cylinder 30 of the extension pipe 6 and the air flow path 31b can be communicated with each other without blocking the front of the air flow path 31b at the storage position.

  FIG. 10 shows a side view of the portable unit 31 in a state where the brush holding unit 41 is stored in the storage unit 6a. On the side surface of the extension pipe 6, a window portion 6 d is formed through which a part of the brush 40 disposed on the rear portion 41 d of the brush holding portion 41 is exposed. Thereby, the brush 40 becomes visible, and the user can be easily informed that the portable unit 31 can be removed from the extension pipe 6 and cleaning can be performed with the brush 40.

  At this time, the brush 40 is provided on the end surface of the brush holding portion 41 where the opening 40b is formed. For this reason, the user's line of sight toward the brush 40 when the grip 8 is gripped is blocked by the brush holder 41. Thereby, since the brush 40 to which dust adheres cannot be visually recognized easily, the fall of the cleanliness at the time of use can be prevented.

  11 and 12 are a side view and a top view showing the brush holding portion 51 at the tip of the extension pipe 32. FIG. 13 shows a sectional view taken along the line CC in FIG. 11, and FIGS. 14 and 15 show sectional views taken along the line AA and BB in FIG. 12, respectively.

  The brush holding part 51 has an opening 51b facing the surface to be cleaned at the tip, and the brush 50 is disposed around the opening 51b. The brush holding portion 51 is pivotally supported by a rotation shaft 51a provided on the side wall of the extension pipe 32, and is held rotatably. The brush holding portion 51 abuts against stoppers 32b and 32c provided on the extension pipe 32, and the rotation range of the brush holding portion 51 is restricted. When the extension pipe 6 is stored in the extension pipe storage part 4f, the brush holding part 51 is disposed at a storage position where it abuts against the stopper 32b as shown in FIG. The brush holding part 51 is arranged on the extension of the extension pipe 32 in the storage position.

  Further, when the brush holding portion 51 is disposed at the storage position, the front portion 51c that is forward of the end surface 32a that the elongated pipe 32 opens is blocked from the upper portion of the opening portion 51b, and the rear portion 51d that is behind is open. Has been. The inner surface of the opened rear portion 51d slides on the side wall of the extension pipe 32, and the brush holding portion 51 rotates. For this reason, the brush 50 provided around the opening 51b is arranged in a U shape in plan view.

  The brush holding portion 51 has an upper surface opening 51e formed on the upper surface facing the opening 51b. The upper wall 32f of the extension pipe 32 passes through the upper surface opening 51e by the rotation of the brush holder 51. An elastic member 52 that is integrally formed with the brush holding portion 51 made of a resin molded product is disposed in the upper surface opening 51e. The elastic member 52 can block the upper surface opening 51e and prevent airflow leakage.

  The elastic member 52 has an S-shaped portion 52a that extends from the front end of the upper surface opening 51e to the rear (the extension pipe 32 side) and meanders in an S-shape. The end surface 32a of the extension pipe 32 is formed as an inclined surface, and the rear end of the S-shaped portion 52a is disposed inside the relative rotation range of the front end of the upper wall of the extension pipe 32 and contacts the end surface 32a. The elastic member 52 has a bent portion 52b that bends upward from the rear end of the S-shaped portion 52a. The bent portion 52b is narrower than the S-shaped portion 52a, and is disposed on the inner side of the extension pipe 32 than the end surface 32a at the storage position.

  When the brush holding part 51 is rotated in the direction in which the front part 51c is upward (clockwise in FIG. 11), the S-shaped part 52a slides on the end face 32a. At this time, since the meandering S-shaped portion 52a is pushed down by the inclined end surface 32a and expands in the vertical direction, the brush holding portion 51 is biased by the elastic member 52 in the direction of the storage position.

  When the brush holding portion 51 is rotated against the urging force of the elastic member, the brush holding portion 51 is disposed at a cleaning position inclined with respect to the storage position as shown in FIG. By rotating the extension pipe 6 with the front end of the brush 50 arranged on the brush holding part 51 in contact with the surface to be cleaned, the brush holding part 51 can be easily arranged at the cleaning position. Accordingly, the ceiling surface and the like can be cleaned by gripping the grip portion 8 of the portable portion 31 integral with the extension pipe 6.

  At this time, the angle of the brush holding part 51 with respect to the holding part 8 can be varied against the urging force of the elastic member 52. For this reason, the opening 51b of the brush holding part 51 can be inclined at a desired angle according to the surface to be cleaned, and cleaning can be performed satisfactorily. Further, when the brush 50 is separated from the surface to be cleaned, the brush holding portion 51 returns to the storage position by the urging force of the elastic member 52.

  As shown in FIGS. 17 and 18, the brush holder 51 whose angle can be changed at the cleaning position can be rotated until it abuts against the stopper 32 c and the opening 51 b is arranged substantially perpendicular to the elongated pipe 32. At this time, the bent portion 52b of the elastic member 52 slides on the flat portion 32d at the end of the upper wall 32f of the extension pipe 32.

  The flat portion 32d is formed at an obtuse angle with respect to the turning radius connecting the turning shaft 51a and the upper wall front end of the extension pipe 32. For this reason, if the brush holding part 51 leaves | separates from a to-be-cleaned surface, the bending part 52b will be returned to a storage position by the component of the circumferential direction of the elastic force which presses the plane part 32d. When the frictional force between the flat surface portion 32d and the bent portion 52b is large, the brush holding portion 51 is maintained at the position of FIGS. 18 and 19, but when the angle of the extension pipe 6 is slightly changed, the brush holding portion 51 is Return to the stowed position.

  Since the brush holding part 51 is urged in the direction of the storage position by the elastic member 52, when the extension pipe 6 integrated with the portable part 31 is stored, the brush holder 51 is arranged at the storage position without requiring a turning operation by the user. The Thereby, the portable part 31 integral with the extension pipe 6 can be quickly attached to the main body part 4 without touching the dust adhering to the brush 50 or the brush holding part 51.

  Further, by bringing the brush 50 into contact with the surface to be cleaned, the brush holding portion 51 is arranged at the cleaning position without requiring a rotating operation by the user. Thereby, it can clean immediately, without touching the dust adhering to the brush 50 or the brush holding | maintenance part 51. FIG.

  In the vacuum cleaner 1 configured as described above, when the electric blower 2 is driven in a state where the extension pipe 6 is attached to the main body portion 4, air is sucked together with dust from the suction port (not shown) of the suction port body 5. The air sucked from the intake port flows into the dust collecting part 3 through the air flow path 4a, and the dust is separated by the centrifugal force due to the turning. The separated dust accumulates in the dust collecting container 3a and is discarded by opening the front panel 4d. The air from which the dust is removed by the dust collecting unit 3 is exhausted from an exhaust port (not shown) through a room in which the electric blower 2 is disposed. Thereby, the floor surface is cleaned.

  At this time, the extension pipe 6 and the inner surface of the extension pipe storage portion 4f are sealed by packing (not shown), and no airflow flows between the extension pipe storage portion 4f and the air flow path 4b. Thereby, the work rate fall of the vacuum cleaner 1 is prevented.

  When the portable part 31 is detached from the main body 4 integrally with the extension pipe 6 by the operation of the hook 11, the extension pipe 32 is pulled out from the tip of the extension pipe 6. At this time, the brush holding part 51 is arranged at the storage position. When the electric blower 2 is driven, air is sucked together with dust from the opening 51 b of the brush holding part 51 at the tip of the extension pipe 32. The air sucked from the opening 51b flows through the extension pipe 32, the outer cylinder 30, the air flow path 31b, and the connection hose 7, and flows into the dust collecting section 3 through the air flow path 4b.
