Japanese Patent Laid-Open No. 10-127536

  However, in the configuration of the conventional vertical vacuum cleaner as described in Patent Document 1, when the dust is sucked from the connection pipe 5, the hose 4 is connected to the cleaner main body 1 of the dust collecting unit 3. Since the hose 4 is stretched in the lateral direction, the distance L from the floor surface to the connecting part of the hose 4 becomes longer, and the cleaner body 1 becomes unstable and falls. It was easy, and it also hindered the cleaning of high places using the connecting pipe 5 and was troublesome.

  This invention solves the said conventional subject, Comprising: It aims at providing the vertical vacuum cleaner which improves the fallability of a vacuum cleaner main body during the cleaning using a connection pipe, and does not produce a fall easily. .

  In order to solve the above-described conventional problems, a vertical vacuum cleaner of the present invention includes a floor suction tool disposed below a vacuum cleaner body having a dust collecting portion, a connection portion of the floor suction tool, and a hose. A connection pipe that communicates with one end of the hose, and a hose connection pipe that communicates the other end of the hose and the dust collecting part, and the hose connection pipe is provided at the connection part, and the hose from the floor surface Since the distance to the connection pipe is reduced, when the user uses the connection pipe with a low-cost configuration, the stand state of the vacuum cleaner main body is stabilized, and it is difficult to fall over and the usability is improved.

  The vertical vacuum cleaner of the present invention is a vertical vacuum cleaner provided with a connection pipe communicating with a hose, and provides an easy-to-use vertical vacuum cleaner that hardly causes the vacuum cleaner body to fall when the connection pipe is used. To do.

  According to a first aspect of the present invention, there is provided a floor suction tool disposed below a vacuum cleaner main body having a dust collecting portion, a connection pipe communicating the connection portion of the floor suction tool and one end of the hose, and other than the hose. A hose connection pipe that communicates the end and the dust collecting part, and the hose connection pipe is provided in the connection part, and the distance from the floor surface to the hose connection pipe is shortened. When the user uses the connection pipe, the stand state of the vacuum cleaner main body is stabilized, and it is difficult to fall down, and the usability is improved.

  In the second invention, in particular, the hose connection pipe of the first invention is arranged so as to project in the lateral direction when the cleaner body is viewed from the front side, and even if the cleaner body is rotated backward, The hose connection pipe improves usability without hindering the rotation of the cleaner body.

  In the third invention, in particular, the hose connection pipe of the first or second invention is provided with an opening connected to the hose at the upper side, the bending stress applied to the hose is reduced, and the durability is improved. I can plan.

  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)
FIG. 1 is an overall perspective view of a vertical vacuum cleaner according to a first embodiment of the present invention, FIG. 2 is an overall perspective view seen from the rear surface of the vertical vacuum cleaner, and FIG. FIG. 4 is a partial cross-sectional view of the vacuum cleaner as viewed from the back side, and FIG. 5 is a perspective view of the vertical vacuum cleaner with a connection pipe removed.

  In FIG. 1 to FIG. 3, an electric blower chamber 12 containing an electric blower 11 is provided below the cleaner body 10, and a dust collection unit 13 is provided at the center. A power supply is provided above the dust collection unit 13. A cord reel accommodating portion 15 in which a cord 14 for use is accommodated is provided. A transport handle 16 is provided at the upper end of the cleaner body 10, and a handle 18 having an extension pipe 17 for operation is provided behind the upper end of the cleaner body 10.

  A floor suction tool 19 is attached to the lower side of the cleaner body 10 so as to be swingable up and down. The floor suction tool 19 is detachable from a holding body 20 provided below the cleaner body 10. Is provided. The other holding body 20 is detachably provided with a connection pipe 21, and this connection pipe 21 communicates with a hose 22, while a hose connection pipe 23 at the other end of the hose 22 is The dust collector 13 communicates with the dust collector 13. A hose connection pipe 23 is connected to a connection portion 24 that connects the floor suction tool 19 and the cleaner body 10.

  3 and 4, the dust suction passage 26 sucked from the suction port 25 of the floor suction tool 19 is connected to the suction port 25 of the floor suction tool 19 via the connecting portion 24 as shown by the arrow direction. It flows through the holding body 20 and flows to the connection pipe 21.

  Dust flowing from the connection pipe 21 flows through the hose 22 and through the hose connection pipe 23 to the connection portion 24, and dust flowing out from the connection portion 24 passes through the suction passage 26 and accumulates on the dust collection portion 13. It is formed with a passage configuration.

  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 is provided at one end so as to be detachable from the connection pipe 21 by taper fitting.

  In addition, the hose connection pipe 23 communicating with the dust collecting unit 13 at the other end of the hose 22 is also substantially L-shaped with respect to the longitudinal direction of the cleaner body 10, and in the lateral direction when the cleaner body 10 is viewed from the front. Protrusively arranged.

  Since the connection pipe 21 is used by the above configuration, as shown in FIG. 5, when the user removes the connection pipe 21 from the holding body 20, the distance A from the floor surface to the hose connection pipe 23 is shortened. In an inexpensive configuration, the stability of the vacuum cleaner main body 10 in the stand state is improved, and it is difficult for the vacuum cleaner body 10 to fall down, thereby improving usability.

  In FIG. 4, the holding body 20 is formed in an approximately L shape with respect to the longitudinal direction of the cleaner body 10, and is disposed behind the cleaner body 10 and in the vicinity of the lower electric blower 11 for taper fitting. Since the connection pipe 21 is detachably attached to the connection pipe 21, the storage operation and the attachment / detachment operation with the holding body 20 are simplified and the usability is improved.

  Further, in FIG. 4, the hose connection pipe 23 communicating with the dust collecting portion 13 at the other end of the hose 22 is substantially L-shaped with respect to the longitudinal direction of the cleaner body 10, and the cleaner body 10 is viewed from the front. Therefore, even if the cleaner body 10 is rotated backward, the hose connection pipe 23 does not hinder the rotation of the cleaner body 10 and the usability is improved. To do.

  4 and 5, the hose connection pipe 23 communicated with the dust collection unit 13 at the other end of the hose 22, and the opening 27 connected to the hose 22 is above the longitudinal direction of the cleaner body 10. Is directed to.

  From the above configuration, when the user removes the connection pipe 21 from the holding body 20 and uses it, the bending stress applied to the hose 22 is reduced, and the durability can be improved.

  As described above, since the vertical vacuum cleaner provided with the connection pipe according to the present invention can realize improved usability and stability, it can be applied to various household and commercial vertical vacuum cleaners.
