  1-9, the vacuum cleaner in this Embodiment is the vacuum cleaner main body 1 which incorporates the electric blower 5 which generates suction wind, and the suction wind which was attached to the cleaner main body 1 and was generated with the electric blower 5. A dust collector 6 that collects dust sucked by the floor, a floor suction tool 2 that is attached to the lower part of the cleaner body 1 and has a first suction port 2a that sucks dust on the surface to be cleaned, and one end of The hose 3 attached to the cleaner body 1 and the extension pipe 4 which has one end attached to the other end of the hose 3 and has a second suction port 4b and can also be used as a suction tool for gaps. .

  The extension pipe 4 is detachably attached to the cleaner body 1, and the extension pipe 4 and the cleaner body 1 are connected to the cleaner body 1 in a state where the extension pipe 4 is attached to the cleaner body 1. An extension tube removal operation unit 7 for releasing the engagement is provided, and when the extension tube removal button 8 is operated by the user while the cleaner body 1 is operating, the operation of the electric blower 5 is stopped. .

  The extension pipe 4 is provided with a handle 4a for moving the electric vacuum cleaner on the floor surface during cleaning work.

  Next, the air path and air flow of the vacuum cleaner in the present embodiment will be described with reference to FIGS. The air P1 mixed with dust sucked from the first suction port 2a of the floor suction tool 2 passes through the flow rate adjusting unit 2b and reaches the merging unit 1c. Similarly, air P2 mixed with dust sucked from the second suction port 4b of the extension pipe 4 also passes through the hose 3 and reaches the junction 1c.

  The junction 1c and the air inlet B6b of the dust collector 6 are in communication, and the dust and air are separated by the mesh filter 6c and the pleat filter 6d. The air inlet A6a of the dust collector 6 and the electric blower 5 are communicated with each other by an air passage 1d formed substantially from the upper rear end of the vacuum cleaner body 1 to the lower side and separated by the dust collector 6. Clean air P3 is sucked into the electric blower 5.

  Further, the exhaust air P4 discharged from the electric blower 5 is discharged to the outside through the exhaust lattice 1e formed at the rear of the cleaner body 1.

  FIG. 2 shows the housed state of the vacuum cleaner, where the vacuum cleaner main body 1 is substantially perpendicular to the floor suction tool 2, and at this time, the floor suction tool 2 is connected to the flow rate adjusting unit 2 b. By narrowing the area, the flow path is blocked. The second suction port 4b is also provided with a seal member 1g that abuts the extension tube 4 in a state in which the extension tube 4 is stored in the extension tube storage portion 1f and maintains airtightness with the cleaner body 1. The flow path of the second suction port 4b is closed.

  6-8, the extension pipe removal operation part 7 is arranged on the inner wall of the movable part 9, the movable part 9 that appears and disappears on the wall surface of the extension pipe storage part 1 f, the extension pipe removal button 8 that operates the movable part 9. And a switch 11 for turning on / off an electric circuit in the cleaner main body 1 by the convex portion 9b of the movable part 9.

  FIG. 6 shows a case where the extension tube removal button 8 is operated by the user when the storage unit is in the retracted state. When the user presses the extension tube removal button 8 (Y direction), the movable part 9 is shown. Moves in the right direction (X direction), the switch 11 is operated by the convex portion 9b of the movable part 9, and the electric blower 5 stops.

  The extension tube 4 is provided with a recess 4c, and the movable part 9 of the extension tube removal operation portion 7 is provided with a claw portion 9a that engages with the recess 4c and holds the extension tube 4 in the cleaner body 1. The claw portion 9a is configured to come into contact with the extension tube 4 when the extension tube 4 is detached from the cleaner body 1, and the extension tube removal operation portion 7 has the claw portion 9a that is an extension tube. While being in contact with 4, the electric blower 5 is stopped.

  When the extension tube 4 is removed from the cleaner body 1 by arranging the position of the claw portion 9a in the vicinity of the storage port 1h of the extension tube storage portion 1f as shown in FIG. 8, the extension tube 4 is removed from the extension tube storage portion 1f. The drive of the electric blower 5 is delayed until it is removed, so that the suction of the extension pipe 4 by the suction air generated by the electric blower 5 can be reduced, and the extension pipe 4 can be easily removed. The relationship between the position L2 of the claw portion 9a and the tube length L1 of the extension tube storage portion 1f is preferably L2 ≧ L1.

  FIG. 9 shows an example of a circuit diagram. The power supply is turned on and off by the operation operation unit 40, and the switch 11 of the extension tube removal operation unit 7 is connected in series with the b contact, and the extension tube is removed. While the switch 11 of the operation unit 7 is operating, the electric blower 5 is stopped.

  10 to 11 are examples in which the opening / closing means of the switch 11 of the extension tube removal operation unit 7 is configured on the extension tube removal button 8 side, and FIG. 11 shows the case where the extension tube removal button 8 is operated by the user. When the user presses the extension pipe removal button 8 (Y direction), the switch 11 is operated by the extension portion 8a of the extension pipe removal button 8, and the electric blower 5 stops.

  With the above configuration, the same effect as that obtained by opening and closing the switch 11 on the movable component 9 side can be obtained.

  FIGS. 12 and 13 show an example in which the switch of the extension tube removing operation unit 7 is configured by the optical switch 12. The optical switch 12 has a stable operation point, and thus the operation of the switch. The accuracy of the point can be improved, and the operating point can be easily adjusted by the shape of the convex portion 9b of the movable component 9.

  Further, FIGS. 14 and 15 show an example in which the extension tube removal button and the movable part (claw) of the extension tube removal operation part are integrated parts, and the operation of the extension pipe removal operation part has a sliding configuration. 15 shows a case where the extension tube removal operation is performed by the user, and the extension tube removal lever 13a of the extension tube removal operation portion 13 is removed in the direction of the arrow X0. The convex part 13b moves in the direction of the arrow X, the switch 11 is operated by the convex part 13b, and the electric blower 5 stops.

  As described above, according to the vacuum cleaner in the present embodiment, the structure can be simplified and an inexpensive vacuum cleaner can be provided by reducing the number of parts.

  As described above, the vacuum cleaner of the present invention is intended to facilitate the removal of the extension pipe, and can be applied to various vacuum cleaners for home use, business use, store use, and the like.
