  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
A vertical vacuum cleaner according to a first embodiment of the present invention will be described with reference to FIGS. 1 is an overall perspective view of the vertical vacuum cleaner according to the present embodiment, FIG. 2 is an overall perspective view of the vertical vacuum cleaner as viewed from the rear surface, and FIG. 3 is a cross-sectional view of the vertical vacuum cleaner. 4 is a partial cross-sectional view of the vertical electric vacuum cleaner as viewed from the back, FIG. 5 is a perspective view of the vertical vacuum cleaner with a connection pipe removed, and FIG. 6 is the vertical electric vacuum cleaner. It is the front view seen from the front of a vacuum cleaner.

  1 to 3, an electric blower chamber 12 containing an electric blower 11 is provided below the vacuum cleaner body 10 of the vacuum cleaner in the present embodiment, and a dust collecting portion 13 is provided at the center. On the upper side of the dust portion 13, a cord reel accommodating portion 15 in which a cord 14 for supplying power is accommodated is provided.

A transport handle 16 is provided at the upper end of the cleaner body 10, and a handle 18 for operation and also having an extension pipe 17 is provided at the rear of the upper end of the cleaner body 10. The floor suction tool 19 is attached below the cleaner body 10 so as to be swingable up and down. The floor suction tool 19 includes a lower end of a holding body 20 provided below the cleaner body 10. It is detachable. One end of a connection pipe 21 is detachably connected to the other side of the holding body 20, and the connection pipe 21 communicates with a hose 22. The other end of the hose 22 communicates with the dust collecting unit 13 and is connected to a connection unit 23 provided on the rear side surface of the cleaner body 10.

  3 and 4, the dust intake passage 25 sucked from the suction port 24 of the floor suction tool 19 passes through the holding body 20 from the suction port 24 of the floor suction tool 19 as indicated by the arrow direction. , Flows to the connection pipe 21. Dust that flows from the connection pipe 21 flows to the connection portion 23 via the hose 22, and the dust that flows from the connection portion 23 is formed in a passage configuration that accumulates to the dust collection portion 13 via the intake passage 25. Yes.

  Moreover, in FIG. 4, the holding body 20 is formed in a substantially L shape with respect to the longitudinal direction of the cleaner body 10, and a connection pipe 21 is detachably connected to one end by taper fitting. Further, at the other end of the hose 22, the connecting portion 23 that communicates with the dust collecting portion 13 is also formed in an approximately L shape with respect to the longitudinal direction of the cleaner body 10, and at the rear and below the cleaner body 10. The electric blower 11 is disposed in the vicinity.

  With the above configuration, when the connection pipe 21 is used, the user removes the connection pipe 21 from the holding body 20 as shown in FIG.
