The hose 2 is housed and held in a state where the extension pipe 3 and the cleaner body 1 are erected in such a manner that the hose 2 is located in the vicinity of the cleaner body 1, that is, at a considerably low place. Is done.

  Next, details of characteristic components of the present invention will be described with reference to FIGS.

  2 shows the hose 2 tip pipe unit 10 during normal use (when the auxiliary hose is stored), and FIG. 3 shows the tip pipe unit 10 when standing and stored (when the sub hose is bent).

  The hose 2 is connected to the main body 1 of the rear end pipe 5 of the hose body 11, and a front end pipe unit 10 connected to the extension pipe 3 is provided on the front end side. The tip pipe unit 10 is housed in a state in which the sub hose 9 is contracted, and includes a tip pipe 8 connected to the hose body 11 and a connection portion 13 connected to the extension pipe 3. . And the handle | steering-wheel 14 grasped during cleaning is provided in the front end pipe 8 substantially in parallel with the hose body 11, and an operation switch 15 for controlling the operation of the cleaner is disposed at a part thereof. Further, the hose body 11 is rotatably held at the rear portion thereof via a connecting pipe A <b> 16, and the end portion of the sub hose 9 is directly connected and fixed to the front portion so as to cover the sub hose 9. The cover 17 of the half is arranged on the outside.

  The cover 17 protects the secondary hose 9 in a straight state when stored. Further, the front portion of the sub hose 9 is connected and fixed to the connecting portion 13, and the connecting portion 13 is sandwiched between half-paired connection covers 18. The connecting portion 13 and the tip pipe 8 are fitted and held in a fitting portion of the cover 17 so as to be rotatable and detachable in a state where the sub hose 9 is straightened. Further, the end pipe 8 is provided with an engaging portion 21 on the side opposite to the handle 14 and an engaged portion 22 that engages with the engaging portion 21 in the stored state shown in FIGS. In the housed state, the cleaner main body 1 and the extension pipe 3 are installed by engaging the engagement means 21 and 22 and the engagement means 6 and 7 between the cleaner body 1 and the extension pipe 3. It can be stored in a state.

  The operation of the above configuration is as follows.

  When the vacuum cleaner is housed, that is, with the vacuum cleaner main body 1 raised, the first engaging portion 6 of the extension pipe 3 is engaged with the first engaged portion 7 of the main body, and the connecting portion 13 is connected to the tip pipe 8.

The portion 22 can be engaged and held. At this time, the connection portion 13 and the top end of the tip pipe 8 are engaged and held at a position where they are almost at the same height.

  As described above, according to the above-described embodiment, the tip pipe unit 10 can be folded back, so that the height from the floor surface in the storage state can be kept low, and the most troublesome in the storage state of the vacuum cleaner. Since the hose body 11 that has been used can be processed at a position adjacent to the extension pipe 3 and at a low position near the vacuum cleaner main body 1, the hose body 11 is generally compact, has a low center of gravity, and can ensure a stable storage state. Is. Further, by making the height of the upper end of the connecting portion 13 and the tip pipe 8 at the time of engagement substantially equal, the auxiliary hose 9 can be bent in a well-balanced manner, and the local burden of the bent portion of the auxiliary hose 9 is concentrated. The purpose is to reduce.

  In addition, the pipe part that accommodates the secondary hose 9 has a straight shape, so that the secondary hose can be stored well and the unevenness of the dust suction passage can be made uniform and smooth as much as possible. In addition, the suction force loss can be suppressed and a high suction force can be maintained.
