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

  At the time of cleaning, an operator grasps the vicinity of the plug portion 38 of the power cord 13 and pulls the power cord 13 from the cleaner body 1.

  At this time, the operator pulls out the power cord 13 while tilting upward toward the rear of the cleaner body 1.

  Then, the outer side portion of the power cord 13 comes into contact with the rear end opening 35 of the cord port cover 23, so that the cord port cover 23 rotates upward about the rotation shaft 43, and the opening direction of the cord outlet 36 Follows the direction in which the power cord 13 is pulled out and tilts upward, and the direction in which the power cord 13 is pulled out changes.

  At the same time, the outer portion of the power cord 13 comes into contact with the rotating member 42, and the rotating member 42 rotates, so that the power cord 13 is smoothly fed out.

  When the drawing of the power cord 13 is stopped, the cord opening cover 23 is returned to a predetermined position by the torsion spring 46.

  Thereafter, the operator connects the plug portion 38 of the power cord 13 to an outlet provided on a wall surface (not shown), operates the predetermined setting button 6 to drive the electric blower 2, and grips the grip portion 7. Then, the floor brush 9 is moved back and forth on the floor surface, and the dust on the floor surface is sucked and cleaned.

  When cleaning is completed, the plug portion 38 is removed from the outlet, and the operator operates the take-up button 49 to rotate the cord reel 14 forward by the spring of the mainspring spring. 13 is wound around the outer periphery of the cord reel 14.

  As described above, in the first embodiment, the cord mouth cover 23 having the cord outlet 36 that allows the power cord 13 to be pulled out of the cleaner body 1 is connected to the cleaner body 1 with a power source. The cord 13 can be pulled out in a different direction.

  More specifically, the cord port cover 23 rotates following the direction in which the power cord 13 is drawn with respect to the cleaner body 1 so that the opening direction of the cord outlet 36 faces the direction in which the power cord 13 is drawn. It was.

  As a result, it is possible to suppress wear of the power cord 13 and the edge of the cord outlet 36 when the power cord 13 is pulled out from the cleaner body 1.

  In particular, since the cord port cover 23 is often formed of a synthetic resin such as ABS that is relatively easily melted by friction so as not to damage the coating of the power cord 13, the friction between the power cord 13 and the cord outlet 36. By suppressing this, it is possible to reliably suppress wear of the cord outlet 36.

  In addition, the pull-out direction of the power cord 13 can be changed with a relatively simple configuration in which the rotary shaft 43 is rotatably fitted in the fitting recess, so that the configuration can be simplified and the manufacturability is improved. In addition, the manufacturing cost can be reduced.

  Further, by providing a rotatable member 42 at the edge of the cord outlet 36, the friction between the edge of the cord outlet 36 and the power cord 13 when the power cord 13 is pulled out and wound is reduced. The wear of the power cord 13 can be more reliably suppressed.

  Then, by providing the rotation shaft 43 of the cord port cover 23 integrally with the rotation member 42, the configuration of the code port cover 23 is compared with the case where the rotation shaft 43 and the rotation member 42 are provided separately. This can be simplified, and the cord port cover 23 can be downsized.

  Further, when the power cord 13 is wound by the cord reel 14, the cord opening cover 23 is returned to a predetermined position by the torsion spring 46, so that when the power cord 13 is wound, the power cord 13 is pulled by the cord outlet 36. Therefore, it is possible to prevent the power cord 13 from being entangled with the cord reel 14 during winding.

  In addition, in the vacuum cleaner, the power cord 13 is wound up relatively quickly by the mainspring spring of the cord reel 14 and the like. There is a possibility that the plug portion 38 jumps up during winding. For this reason, the cord port cover 23 is rotated only when the power cord 13 is pulled out so that the opening direction of the cord outlet port 36 is directed upward, and the winding direction is directed horizontally when winding. The power cord 13 can be easily pulled out, and the plug portion 38 can be prevented from jumping up during winding, thereby improving usability.

  Further, by providing the closing plate portion 37 on the upper surface portion 32 of the cord port cover 23, the interior of the cleaner body 1 is connected to the drawer mounting port 21 even if the cord port cover 23 is rotated with respect to the cleaner body 1. It is possible to prevent dust and the like from entering the cleaner body 1 without being exposed to the outside from the top.

  Then, by providing the cord port cover 23 at a position closer to the upper side of the rear portion of the cleaner body 1, the power cord 13 can be easily pulled out and wound around the cleaner body 1, and the power cord 13 can be wound up. In this case, the plug portion 38 of the power cord 13 can be prevented from jumping up against the floor surface.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
