  When cleaning is completed, the user operates the setting button 64 to stop the electric blower 34 by the control means 35. And the vacuum cleaner 11 is attached to a support device, and it is set as an accommodation state.

  According to the embodiment described above, the intake communication port 54 and the exhaust communication port 55 are opened facing the dust collector 22 in the direction intersecting the axis A of the extension pipe 16, and the exhaust communication port 55 is disposed on the rear side opposite to the main body connection port 41 with respect to the intake communication port 54, and the electric blower 34 is on the axis A of the extension pipe 16 and is connected to the exhaust communication port 55. Is disposed in the main body portion 21 on the front side, which is the main body connection port 41 side of the exhaust communication port 55, so that the dust collecting device 22 can be bent with the minimum number of bending times of the dust-containing air flowing linearly through the extension pipe 16. And is sucked into the electric blower 34 without taking a long air passage from the dust collector 22. Therefore, the air path distance until the electric blower 34 is sucked can be shortened, and the dust-containing air sucked through the extension pipe 16 flows into the dust collector 22 while maintaining the inertia, so that the suction efficiency is reduced. Can be prevented.

  Further, the electric blower 34 can be arranged in a compact manner by arranging the electric blower 34 in the main body 21 in the space between the intake communication port 54 and the exhaust communication port 55.

  That is, in the case of the stick type vacuum cleaner 11 in which the extension pipe 16 is directly connected to the cleaner body 15, it is required to suppress the size of the cleaner body 15, and the arrangement of the electric blower 34 is limited. Therefore, the electric blower 34, the intake communication port 54, and the exhaust communication port 55 are arranged by effectively using the space of the main body part 21, and the dust collector 22 is arranged along the main body part 21, thereby cleaning. Without enlarging the machine main body 15, the air path distance until it is sucked into the electric blower 34 can be minimized.

  In the above-described embodiment, in addition to the secondary battery 36, for example, a cord reel device that takes power from an external power source using a power cord can be used as the power source.

  Although one embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
