  As shown in FIG. 3, the dust remover 7 is pivotally supported by a shaft A <b> 8 at the bottom of the main body 1 and is rotatable. Further, behind the axis A8 of the dust removing body 7, there is provided a vibration arm body 10 that is linked to the dust removing body 7 and biased upward by a spring body 9 that is biasing means. A cord reel 13 is rotatably supported on a partition wall 21 (see FIG. 4) accommodated in the main body 1 by a shaft B11, and can be accommodated by winding a power cord 12 for supplying electric power to the electric blower 2. Further, the cord reel case 13 is provided with four rib bodies 14 (see FIG. 8) which periodically press the vibration arm body 10 to give vibration when rotating. Further, the cord reel case 13 includes a spring 15 and is biased in a left-handed direction that is a storage direction of the power cord 12.

  A brake lever 17 is pivotally supported on the partition wall 21 by a shaft C16 and is rotatably attached to a position where the rotation of the cord reel case 13 is stopped and released. Similarly, a release lever 18 provided on the partition wall 21 is slidable in the vertical direction and can press the vibration arm body 10 downward. A position 18 a of the release lever 18 that presses the vibration arm body 10 is set between the axis A <b> 8 of the dust removing body 7 and the spring body 9.

  Here, the brake lever 17 and the release lever 18 are arranged close to each other so that they can be operated with one operation button. That is, the brake lever 17 is rotated to the position in the release direction of the cord reel case 13, the pressing portion 19 of the brake lever 17, and the release lever 18 is slid in the pressing arm body 10 in the pressing direction. An operation button 26 is provided that closes the pressing portion 20 and covers them simultaneously. Specifically, as shown in FIG. 10, the size of the operation button 26 is set to φ50 mm, and the pressing portion 19 of the brake lever 17 and the pressing portion 20 of the release lever 18 are provided at close positions within φ50 mm. It is configured to be provided at substantially the same position from the center of the button 26 and to be covered with the operation button 26 at the same time. Further, the pressing portion 20 of the release lever 18 is set at a position higher than the pressing portion 19 of the brake lever 17.

  Further, as shown in FIG. 11, the release lever 18 is in a reverse position separated from the cord reel case 13 by the partition wall body 21 and formed by the partition wall body 21 and the wall 22 of the main body 1. 23. Further, the vibration arm body 10 includes a position restricting rib body 24 (see FIG. 12) at a position where it abuts the main body 1 when it is pressed about 10 degrees counterclockwise by being pressed by the release lever 18 at the front portion of the axis A8. . Further, the vibrating arm body 10 includes a partly thin portion 25 in the vicinity of the axis A8. On the other hand, the release lever 18 is made of POM resin, and the vibration arm body 10 is made of ABS resin, and each is made of different materials.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 12 shows an operation explanatory diagram when the power cord 12 is pulled out. Before starting the cleaning, when the power cord 12 is pulled out from the cleaner body 1, when the power cord 12 is pulled out, the cord reel case 13 rotates counterclockwise at the same time, and the four locations provided in the cord reel case 13 are provided. The rib body 14 periodically hits the vibration arm body 10. At that time, the dust removing body 7 interlocked with the vibration arm body 10 periodically vibrates back and forth with the axis A8 as a fulcrum and strikes the paper bag 3. The fine dust adhering to the surface of the paper bag 3 is dropped by the vibration, the clogging of the paper bag 3 is eliminated, and the suction force can be maintained without being clogged as compared with the case without vibration.

  FIG. 13 shows an operation explanatory diagram when the power cord 12 is stored. When cleaning is completed and the power cord 12 is housed in the cleaner body 1, when the operation button 26 is pressed downward, the pressing portion 20 of the release lever 18 hits the operation button 26, and the release lever 18 moves downward. And the release lever 18 presses the vibration arm body 10 to move the vibration arm body 10 to a position where it does not come into contact with the rib body 14. Immediately thereafter or almost simultaneously, the pressing portion 19 of the brake lever 17 is pressed by the operation button 26, and the brake lever 17 rotates about the axis C16 and moves to a position where the rotation of the cord reel case 13 is released. The cord reel case 13 in which the stopper by the brake lever 17 has been removed rotates clockwise by the spring force of the mainspring spring 15, winds up the power cord 12, and stores the power cord 12 in the cleaner body 1. When the power cord 12 is stored, the vibration arm body 10 is moved to a position that does not come into contact with the rib body 14, so that the paper bag 3 is not vibrated, and is caused by the dust removing body vibration when the power cord 12 is stored. Noise reduction and resistance of rotation of the cord reel case 13 can be reduced, and the power cord 12 can be stored smoothly. Further, when the vibration arm body 10 is pressed and rotated counterclockwise by about 10 degrees, even if the position restricting rib 24 provided at the front portion of the axis A8 hits the main body 1 and is further pressed by the release lever 18, the vibration is not applied. The arm body 10 is bent by the thin portion 25, and the dust removing body 7 is configured not to rotate any further.

  When the power cord 12 is stored, the size of the operation button 26 is φ50 mm, and the pressing portion 19 of the brake lever 17 and the pressing portion 20 of the release lever 18 are close to a position within φ50 mm, so one finger can be used. By pressing the operation button 26, the brake lever 17 and the release lever 18 can be simultaneously pressed reliably and easily, and usability can be improved. Even when the center of the operation button 26 is not pressed, the size of the operation button 26 is φ50 mm, which is a size that can apply force to the whole with one finger, so that not only one but also the brake Both lever 17 and release lever 18 can be reliably pressed and operated.

  In addition, since the pressing portion 19 of the brake lever 17 and the pressing portion 20 of the release lever 18 are provided at substantially equal positions from the center of the operation button 26, the brake lever 17 The force can be evenly transmitted to the release lever 18, the brake lever 17 and the release lever 18 can be operated more reliably, and the usability can be improved.

  On the other hand, since the pressing portion 20 of the release lever 18 is provided at a position higher than the pressing portion 19 of the brake lever 17, the release lever 18 can be surely pressed earlier than the brake lever 17 and operated. By controlling the dust removing body 7 prior to storing the power cord 12 with a simple configuration, it is possible to reliably prevent the dust removing body from operating when the cord is stored. Since the operation noise and resistance of the body 7 can be reliably eliminated and the power cord 12 can be stored smoothly, the usability can be improved. This may be configured in any way as long as the operation button 26 operates the release lever 18 before the brake lever 17. For example, the brake lever 17 and the release lever 18 are set at the same height. The height of the pressed portion of the operation button 26 to be pressed may be changed.

  Further, since the release lever 18 is provided at the opposite position separated from the cord reel case 13 by the partition body 21, the power cord 12 can be stored smoothly without the release lever 18 interfering with the power cord 12. Further, the release lever 18 is not affected by the heat of the power cord 12, can prevent thermal deformation, and can further improve usability.

  Further, since the release lever 18 is provided in the release lever storage chamber 23 that is isolated from the surroundings, it is not affected by the heat of the electric blower 2 and the heat of the exhaust and the heat of the power cord 12 and prevents thermal deformation. Can do. Further, fine dust due to exhaust from the electric blower 2 does not adhere to the release lever 18, and friction of the release lever 18 due to fine dust adhesion can be reduced. Furthermore, there is no interference with the power cord 2 and the like, and the release lever 18 can be operated more reliably, improving usability.

  In addition, since the release lever storage chamber 23 is provided by the partition wall 21 and the wall 22 of the main body, the release lever storage chamber 23 isolated from the surroundings can be configured without using separate parts such as a lid. The number of parts can be reduced, and the usability can be improved at low cost.

  Further, since the position of the release lever 18 that presses the vibration arm body 10 is set between the axis A8 of the dust removing body 7 and the spring body 9, the position of the release lever 18 that presses the vibration arm body 10 is set. Even when the sliding lever 7 is close to the axis A8 of the dust removing body 7 and the sliding distance of the release lever 18 is short, the vibrating arm body 10 can be rotated greatly, and accordingly the sliding operation of the operation button 26 by the user can be performed accordingly. It can be reduced and usability can be improved. Further, since the sliding distance of the release lever 18 can be reduced, the size of the cleaner body 1 can be further reduced.

  Further, no matter how much the vibration arm body 10 is pressed by the release lever 18, the rotation is restricted by the position restriction rib body 24 at a rotation angle of about 10 degrees, and then the vibration arm body 10 is deformed by deflection. Therefore, the sliding distance of the release lever 18 and the rotating distance of the vibration arm body 10 can be set separately and freely. Therefore, since the optimal sliding distance of the operation button 26 and the rotational distance of the dust remover 7 can be set respectively, the usability can be improved.

  Furthermore, since the vibration arm body 10 is provided with the thin portion 25, the thin arm portion 10 is further pressed when the vibration arm body 10 is further restricted by the position restriction rib body 24 and then pressed by the brake lever 17. Since 25 is easy to bend and the force of the brake lever 17 can be surely released, the usability can be improved.

  Further, since the release lever 18 is made of POM resin and the vibration arm body 10 is made of a material different from ABS resin, it is possible to reduce wear due to friction when the release lever 18 and the vibration arm body 10 come into contact with each other. The service life can be extended, so the usability can be improved.

  The dust removing body 7 is pivotally supported on the main body 1 by an axis A8 and is rotatable. The dust removing body 7 is attached to the rear side of the axis A8 of the dust removing body 7 with a spring body 9 as an urging means in conjunction with the dust removing body 7. A biased vibration arm body 10 is provided. On the other hand, a brake lever 17 is provided which is pivotally supported by a shaft C16 and is rotatably attached to a position where the rotation of the cord reel case 13 is stopped and a position where the cord reel case 13 is released. Moreover, the release lever 18 which can be slid to the up-down direction and can press the vibration arm body 10 downward is provided. The position of the release lever 18 that presses the vibration arm body 10 is provided at a position away from the distance of the spring body 9 from the axis A8 of the vibration arm body 10.

  Further, a partition wall body 21 that pivotally supports and holds the cord reel case 13 is provided, and a release lever 18 is disposed between the partition wall body 21 and the cord reel case 13.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the power cord 12 is stored in the cleaner body 1, when the operation button 26 is pressed downward, the pressing portion 20 of the release lever 18 hits the operation button 26, and the release lever 18 slides downward, Further, when the release lever 18 presses the vibration arm body 10, the vibration arm body 10 is moved to a position that does not come into contact with the rib body 14, as in the first embodiment.

  In the second embodiment, since the position of the release lever 18 that presses the vibration arm body 10 is separated from the axis A8 of the vibration arm body 10, the vibration arm body 10 is rotated with a light force. Therefore, it is possible to improve the usability without giving an extra burden to the operation of pressing the operation button 26.

  As described above, since the vacuum cleaner according to the present invention can reliably and easily store the power cord and suppress the operation of the dust removing body with one finger when storing the power cord, It is particularly useful for commercial vacuum cleaners.
