The extension pipe storage portion 4f stores the distal end portion of the extension pipe 6, and the extension pipe 6 can be detached from the main body portion 4 as shown in FIGS.

  In FIG. 5, the extension pipe 6 is configured as a double pipe, and an extension pipe 32 is fitted into the outer cylinder 30. When the extension pipe 6 is detached from the main body 4, the extension pipe 6 can be extended by pulling out the extension pipe 32 from the tip of the outer cylinder 30. A brush holding portion 51 having a brush 50, which will be described in detail later, is rotatably disposed at the distal end of the extension pipe 32.

  Moreover, the portable part 31 can be detached from the extension pipe 6 as shown in FIGS. Thereby, the portable part 31 can be removed in the state which attached the extension pipe 6 to the main-body part 4. FIG.

  In FIG. 7, the portable part 31 has the air flow path 31b connected to the upper support part 31a inside. The connection hose 7 and the outer cylinder 30 of the extension pipe 6 communicate with each other via an air flow path 31b. Thereby, the extension pipe 6 extends the air flow path 31 b communicating with the connection hose 7.

  A brush holding unit 41 is rotatably disposed at the tip of the portable unit 31. The brush holding portion 41 has an opening 41b at the tip, and the brush 40 is disposed around the opening 41b. A storage portion 6 a for storing the brush holding portion 41 is provided along the outer cylinder 30 in the extension pipe 6. The brush holding portion 41 is rotatably arranged by a rotation shaft 41a perpendicular to the air flow path 31b, and an elastic member 42 including a torsion spring that urges the brush holding portion 41 in the clockwise direction is provided in the drawing.

  Therefore, when the portable part 31 is detached from the extension pipe 6 and taken out from the storage part 6a, the brush holding part 41 is rotated and arranged at the cleaning position as shown in FIG. At this time, the brush holding portion 41 is placed at a predetermined angle in contact with a stopper 31c (see FIG. 9) provided on the portable portion 31.

  When the portable part 31 is attached to the extension pipe 6, the tip of the brush holding part 41 slides against the inner wall 6b (see FIG. 7) of the storage part 6a against the urging force of the elastic member 42. Thereby, the brush holding | maintenance part 41 is distribute | arranged to the accommodation position shown in FIG. 7, and is accommodated in the accommodating part 6a.

  FIG. 9 shows a side cross-sectional view of the main part of the portable part 31. The air flow path 31b is formed in a rectangular cross section, and one end of the opening 41b of the brush holding part 41 at the cleaning position extends to the outside in the radial direction of the air flow path 31b. Thereby, the desk etc. can be cleaned in the wide range to the outer side of the air flow path 31b by holding the holding part 8 of the portable part 31 in which the brush holding part 41 is arranged at the cleaning position.

  At this time, the angle of the brush holding portion 41 with respect to the grip portion 8 can be varied against the urging force of the elastic member 42. For this reason, according to the to-be-cleaned surface, the opening part 41b of the brush holding | maintenance part 41 can incline to a desired angle, and it can clean favorably.

  Further, when the brush holding portion 41 is arranged at the cleaning position and the holding portion 8 is held, the front portion 41c which is the front side of the brush holding portion 41 is closed above the opening portion 41b, and the rear portion 41d which is the rear side. Is open. The inner surface of the opened rear portion 41d slides on the side wall of the air flow path 31b, and the brush holding portion 41 rotates. For this reason, the brush 40 provided around the opening 41b is arranged in a U shape in plan view.

  Since the brush holding portion 41 is urged in the direction of the cleaning position by the elastic member 42, when the portable portion 31 is detached from the extension pipe 6, the brush holding portion 41 is arranged at the cleaning position without requiring a turning operation by the user. Thereby, it can clean immediately, without touching the dust adhering to the brush 40 or the brush holding | maintenance part 41. FIG.

  Further, since the brush holding portion 41 slides against the inner wall 6b (see FIG. 7) and rotates against the urging force of the elastic member 42 when being stored in the storage portion 6a, the user can perform a rotation operation. Arranged in the storage position without need. Thereby, the portable part 31 can be quickly attached to the extension pipe 6 without touching the dust adhering to the brush 40 and the brush holding part 41, and the brush holding part 41 can be accommodated.

  At this time, the rotation shaft 41a is arranged on the outer side in the radial direction of the air flow path 31b and on the front side with respect to the air flow path 31b standing when the grip portion 8 is gripped and the brush 40 is used. The 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, and one end of the opening 41b is at the air flow path at the storage position. It arrange | positions ahead rather than the end surface of 31b.

  As a result, the brush holder 41 protruding forward at the cleaning position has a reduced amount of radial protrusion from the air flow path 31b at the storage position, and the brush holder 41 can be stored in a space-saving manner. Further, 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.

  Further, the rotation shaft 41a of the rotating brush holding portion 41 and the upper surface of the front portion 41c are close to each other. For this reason, the upper surface of the brush holding part 41 which rotates by sliding the upper surface of the front part 41c on the cylindrical surface concentric with the rotating shaft 41a provided in the portable part 31 can be easily blocked. Therefore, airflow leakage can be prevented.

  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 storage 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.
