  The connection pipe 13 is provided so as to be rotatable in the front-rear direction, which is a direction orthogonal to the rotation direction of the rotary tube 12.

  Next, the operation of the above embodiment will be described.

  First, the operator sequentially connects the hose body 4, the extension pipe 8, and the suction port body 9 to the main body suction port 3 of the cleaner body 1.

  Further, when the operator pulls out the power cord from the cleaner body 1 and connects it to an outlet (not shown), and then operates the predetermined setting button 7 by holding the holding portion 6, the operation mode set by the setting button 7 is set. Accordingly, the electric blower 2 is driven.

  Then, the operator grips the grip portion 6 and causes the suction port body 9 to run forward and backward on the floor surface, and sucks dust together with air from the suction port 15.

  At this time, the turning means 48 detects the turning by turning so that the turning wheel 48 follows the running of the suction port body 11 in the front-rear direction, and corresponds to the detected running direction of the suction port body 11. The control means 28 controls the power supplied to the motor 27 and the driving force of the motor 27 is transmitted via the belt 39, so that the rotary cleaning body 26 is reversed with respect to the traveling direction of the suction inlet body 11. Rotate in direction or forward direction.

  Specifically, as the turning wheel 48 turns, the cam portion 68 rotates eccentrically with respect to the main body shaft portion 62, so that the detection roller 74 that is in rolling contact with the outer peripheral portion of the cam portion 68 is moved to the outer periphery of the cam portion 68. The tip end side of the arm portion 72 is swung according to the uneven shape of the portion, and the detection switch 71 is turned on / off according to the uneven shape of the cam portion 68.

  That is, when the detection roller 74 is in rolling contact with the outer peripheral portion of the first region 75 of the cam portion 68, the arm portion 72 is not pushed into the detection switch 71 side, and is applied to the detection switch 71 by the urging force. In this embodiment, the detection switch 71 is turned off, the control means 28 determines that the suction port body 11 is moving forward, and the detection roller 74 is connected to the cam portion. In the case of rolling contact along the outer peripheral portion of the second region 76 of 68, the arm portion 72 is pushed against the urging force, the detection switch 71 is turned on, and the suction port body 11 is turned on by the control means 28. Is determined to be moving backwards.

  As a result, the detection switch 71 is turned on / off corresponding to the traveling direction of the suction port body 9, and this on / off detection result is output to the control means 28.

  The control means 28 to which the on / off detection result is input controls the power supplied to the motor 27 and the driving force of the motor 27 is transmitted via the belt 39, whereby the rotary cleaning body 26 rotates.

  During this rotation, the direction having a predetermined relationship with the traveling direction of the suction port body 11, in the present embodiment, the rotational cleaning body 26 is opposite to the traveling direction of the suction port body 11, that is, along the opposite direction. Rotate. In other words, when the detection switch 71 is off, the rotary cleaning body 26 is rotated backward, and when the detection switch 71 is on, the rotary cleaning body 26 is rotated forward.

  When the suction port body 9 comes into contact with an obstacle W such as a wall, as shown in FIG. 2 (a), the front cover 19 rotates backward against the urging force of the cover torsion spring. The rotary cleaning body 26 abuts against the rotation restriction step surface S at the rear of the suction chamber 21 and protrudes forward relative to the front suction port 18 of the suction port body 11.

  Further, when the suction port body 9 is pressed against the obstacle W, the lower front cover 87 moves backward against the upper front cover 85 against the urging force of the torsion spring 94 as shown in FIG. And the tips of the blades 33a and the bristles 33b protrude below the lower front cover 87 and are located between the lower front cover 87 and the floor, respectively, below the lower front cover 87. The blade 33a and the brush bristles 33b scrape up and clean the dust on the floor near the wall. When the suction port body 9 is separated from the obstacle W, the front cover 19 returns to the original state by the urging of the torsion spring 94 and the urging of the cover torsion spring.

  Dust sucked from the suction port body 9 is conveyed from the main body suction port 3 to the dust collection pack via the extension pipe 8 and the hose body 4 and collected.

  When the rotary cleaning body 26 of the suction port body 9 is to be maintained after being used for a predetermined period, the operator rotates the lock portions 36a, 36a of the side covers 36, 36 to move the side covers 36, 36. The both ends of the rotating shaft 31 of the rotary cleaning body 26 are removed together with the bearings 34 and 34 from the exposed recesses 35 and 35 while being removed from the lower case 16 and holding the front cover 19. At this time, one bearing 34 is also removed from the belt 39 wound around the motor 27.

  Then, the operator removes dust entangled with the rotating shaft 31, the dust scraping member 33, and the like.

  Thereafter, when cleaning the front cover 19, the front cover 19 is removed from the rotary cleaning body. When the maintenance is completed, both ends of the rotary shaft 31 of the rotary cleaning body 26 are pushed into the engagement notch 89 from the attachment / detachment space 90, and the front cover 19 is integrated with the rotary cleaning body 26.

  Then, the front cover 19 and the rotary cleaning body 26 are attached to the suction inlet main body 11 by the operation opposite to that at the time of removal. That is, the front cover 19 is positioned on the front suction port 18 side, the bearings 34 at both ends of the rotary cleaning body 26 are inserted into the recesses 35, and the belt 39 is wound around the outer peripheral surface of one bearing 34. Thus, each side cover 36 is attached to both side portions of the lower surface of the lower case 16 so as to cover each recess 35, and each side cover 36 is fixed to the lower case 16 by rotating each lock portion 36a.

  As described above, according to the embodiment, the front cover 19 can be attached to and detached from the rotating shaft 31 of the rotary cleaning body 26, and the front cover 19 can be attached and detached integrally with the rotary cleaning body 26. Since the rotary cleaning body 26 and the front cover 19 can be simultaneously removed from the suction inlet body 11 with one touch, the maintainability is improved as compared with the case where the rotary cleaning body and the front cover are removed separately.

  Since the maintainability can be improved in this way, the cleaning performance of the rotary cleaning body 26 can be maintained.

  Further, since the front cover 19 and the rotary cleaning body 26 can be removed while gripping the front cover 19, the rotary cleaning body 26 contaminated by dust can be removed without being gripped by an operator, which is hygienic.

  Furthermore, the rotary cleaning body 26 removed from the suction port body 11 is supported by the front cover 19 only in the vicinity of both end portions of the rotary shaft 31 by placing the front cover 19 on the placement surface, and other parts. Does not come into contact with the front cover 19 or the mounting surface, so that the rotating cleaning body is placed on the mounting surface, for example, as in the conventional case where the rotating cleaning body is removed alone. By doing so, it is possible to protect the dust cleaning member 33 of the rotary cleaning body 26 without causing the bristles of the dust cleaning member in contact with the mounting surface to bend and sleep due to the weight of the rotary cleaning body. Scraping performance can be secured.

  And the convenience of a vacuum cleaner can be improved by providing such a suction inlet 9.

  In the above-described embodiment, the configuration of the swivel wheel 48 and the detection unit 67, the mounting structure of the front cover 19 to the rotary cleaning body 26, that is, the shape of the detachable space 90 and the engagement notch 89, etc. It is not limited to.

  Further, as the case member other than the front cover 19, the above configuration can be applied as long as it is a part of the suction inlet main body 11 in the vicinity of the rotary cleaning body 26, for example.

  Furthermore, the details of the vacuum cleaner are not limited to the above configuration, and the vacuum cleaner is not limited to the canister type, and may be, for example, a self-propelled vacuum cleaner or the like. However, even an upright type or a handy type directly formed on the lower surface of the cleaner body 1 can be used correspondingly.
