  The handle 1 is rotatable between a position rotated upward as shown in FIG. 5A and a position rotated downward as shown in FIG. 5B.

  As shown in FIG. 5 (a), with the wheel body 105 and the casters 106 in contact with the vacuum cleaner main body 5, the handle 1 is moved upward to raise the position of the handle portion 3. However, the grip portion 3 can be easily gripped.

  In the stowed state in which the cleaner body 5 is upright and the hose 104 connecting the floor suction tool 101 and the extension pipe 102 is connected to the cleaner body 5 and the stopper 17 of the extension pipe 102 is locked in the locking groove 13. When the handle 1 is rotated to the position indicated by the solid line in FIG. 5B and FIG. 7, the handle portion 3 is set to be positioned above the substantially vertical line of the center of gravity 12 of the stored vacuum cleaner 100.

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

When the vacuum cleaner 100 is driven, the electric blower 6 is driven to generate suction air, and dust on the surface to be cleaned is sucked from a suction port (not shown) provided on the lower surface of the floor suction tool 101 and extended. It flows into the cleaner body 5 through the tube 102 and the hose 104 and is collected by the dust bag 8. In the cleaning state, by rotating the handle 1 to the upper side of the cleaner body 5, the position of the handle portion 3 can be increased, and the user can easily hold the handle portion 3. The mobility of the main body 5 can be improved.

  When the cleaner body 5 is housed, the handle portion 3 is gripped to bring the grounding portion 15 on the rear surface of the cleaner body 5 into an upright state. At that time, the handle 1 rotates upward in the upright state due to its own weight. With the hose 104 connecting the floor suction tool 101 and the extension pipe 102 connected to the cleaner body 5, the stopper 17 of the extension pipe 102 is locked in the locking groove 13 to be in the storage state.

  In a conventional vacuum cleaner, the handle is positioned above the vacuum cleaner body so that it can be easily gripped with the wheels of the vacuum cleaner grounded. Is formed on the bottom of the vacuum cleaner body, and when lifting the vacuum cleaner in the stored state by gripping the handle part, the weight balance is poor, it is difficult to carry with a large inclination, and it is carried because the inclination is large There was a risk that the extension pipe would be unlocked and dropped due to shaking or the like, and the floor surface could be damaged.

  Further, since the vacuum cleaner is greatly inclined, the load applied to the stopper and the locking groove becomes very large. There is a risk that the stopper or locking groove may be damaged or fall off the locking groove due to excessive load, so the hose, extension pipe, and floor suction tool are connected to the vacuum cleaner body. When carrying it with a hand, you carry the main body of the vacuum cleaner with one hand and move it with an extension pipe or the like with the other hand. At this time, the vacuum cleaner hits the wall when moving through a narrow passage, or both hands were blocked, so it was necessary to place the vacuum cleaner on the ground when opening the door, and so on, it was inconvenient .

  In the vacuum cleaner of the present invention, since the center of gravity of the vacuum cleaner 100 is positioned substantially below the handle portion 3 in the storage state of the vacuum cleaner 100, the vacuum cleaner 100 is lifted in the storage state. In this case, the vacuum cleaner 100 can move while maintaining a stable state without being greatly inclined. Moreover, since generation | occurrence | production of the twisting force between the stopper 17 and the locking groove 13 which arises when the vacuum cleaner 100 tilts can be suppressed, damage can be suppressed. Furthermore, since the handle 1 can be rotated, vibration generated during movement can be absorbed by the rotation of the handle 1, and the vacuum cleaner 100 may be in an unstable state such as being tilted unexpectedly. This can be prevented and the transportability in the stored state can be improved.

  As described above, since the electric vacuum cleaner of the present invention can be stably carried, for example, even when moving in a narrow passage in the housed state, attention should be paid to only one side having the electric vacuum cleaner 100. Therefore, the danger of hitting a wall or the like can be suppressed. Moreover, since the vacuum cleaner 100 in the housed state can be transported stably with one hand, the door can be opened without placing the vacuum cleaner 100, and usability can be improved.

  The locking groove 13 of the electric vacuum cleaner 100 of the present invention is preferably formed at least in the side cover body 4 on the cord reel chamber 11 side. The electric blower chamber 7 located on the opposite side of the cord reel chamber 11 has a built-in electric blower 6 which is a heavy object, and the extension pipe 102 to which the floor suction tool 101 is connected is connected to a light weight cord reel 10. By locking to the stored code reel chamber 11 side, the weight balance in the left-right direction of the vacuum cleaner 100 when carrying the vacuum cleaner 100 can be improved.

Moreover, the latching groove | channel 13 can also be formed in the side surface cover body 4 of both sides. By forming on the side cover bodies 4 on both sides, either the left or right locking groove 13 depending on the storage location or usage state.
In addition, the extension tube 102 can be locked, and the usability can be improved.

  As described above, the vacuum cleaner according to the present invention can improve the portability in a state in which the hose, the extension pipe, and the floor suction tool are integrally stored in the vacuum cleaner body, so that it is particularly suitable for home use, business use, etc. Useful for vacuum cleaners.
