 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 4, reference numeral 1 denotes an electric vacuum cleaner body to which wheels 2 are attached. The electric vacuum cleaner body 1 has an internal motor as in the conventional case. A suction fan (not shown) rotated by is provided.

Reference numeral 3 denotes a flexible connection pipe detachably attached to the suction port 4 of the vacuum cleaner body 1, and the connection pipe 3 is a connection pipe 5 detachably attached to the suction port 4. The connecting pipe body 6 is connected to the connecting pipe 5, and the hose grip 7 is connected to the tip of the connecting pipe body 6.

Reference numeral 8 denotes an operation pipe connected to the connection pipe 3, and a T-shaped nozzle 9 for sucking dust on the floor is detachably attached to the tip end of the operation pipe 8. The operation pipe 8 may have a structure in which a plurality of operation pipes 8 are separably connected so that the length thereof can be adjusted.

Reference numeral 10 denotes an auxiliary pipe having an auxiliary passage 11 formed at a rear end portion of the operation pipe 8 and communicating with a passage 8a of the operation pipe 8.

Reference numeral 12 is a switching valve provided at the rear end of the operation pipe 8 for selectively opening and closing the auxiliary passage 11 and the passage 8a.

Reference numeral 13 denotes an auxiliary operation pipe attached to the auxiliary pipe 10 via a flexible auxiliary operation pipe 14 which can be expanded and contracted. At the tip of the auxiliary operation pipe 13, dust at corners and crevasses is collected. The crevasse nozzle 15 that sucks in is formed.

Reference numeral 16 is a locking tool for locking the auxiliary operation pipe 13 formed on the operation pipe 8.

In the electric vacuum cleaner 17 having the above-mentioned configuration, when performing the cleaning work of the floor surface, since the passage of the auxiliary pipe 13 is closed by the switching valve 12, the T-shaped nozzle 9 is attached to the tip of the operation pipe 8. Can be attached to drive the electric vacuum cleaner body 1 to suck dust through the T-shaped nozzle 9, the operation pipe 8 and the connection pipe 3.

When cleaning the corners and crevasses, switching the switching valve 12 and closing the passage 8a of the operation pipe 8 causes the crevasse nozzle 15, the auxiliary operation pipe 13, the auxiliary connection pipe 14 and the connection pipe 3 to be closed. Dust can be sucked into the vacuum cleaner 1 via the vacuum cleaner.

[Different embodiment of the present invention]

 Next, another embodiment of the present invention shown in FIGS. 5 to 10 will be described. In the description of these embodiments, the same components as those of the first embodiment of the present invention will be designated by the same reference numerals, and duplicate description will be omitted.

The second embodiment of the present invention shown in FIGS. 5 and 6 is mainly different from the first embodiment of the present invention in that the auxiliary pipe 10 is formed on the hose grip 7 A of the connection pipe 3. However, in the vacuum cleaner 17A having such a configuration, the switching valve 12 for selectively opening and closing the auxiliary passage 11 and the passage 8a of the auxiliary pipe 10 is provided. The same effect as the example can be obtained.

The third embodiment of the present invention shown in FIGS. 7 to 10 is mainly different from the first embodiment of the present invention in that the operation pipe 8A is protruded and retracted from the tip of the operation pipe 8A. Auxiliary operation pipe 13A having a crevice nozzle 15 formed at the tip end thereof can be slidably installed, and when the auxiliary operation pipe 13A is projected, the passage 8a at the tip end of the operation pipe 8A is closed, and Even if the electric vacuum cleaner 17B configured as described above is provided with the switching valve 12A, the switching valve 12A that can open the passage 13a of the operation pipe 13A and the passage 8a at the rear end of the operation pipe 8a is provided. The same effect as that of the embodiment can be obtained.
