  About the vacuum cleaner comprised as mentioned above, the connection structure is demonstrated below.

  First, the connection between the connecting pipe 3 and the first pipe portion 8 of the small suction tool 5 will be described.

  As shown in FIG. 4B, when the first pipe portion 8 of the small suction tool 5 is inserted into the other end 4 of the connecting pipe 3 opposite to the side to which the hose 2 is connected, the fixing pin 10 is It is pushed into the inside of the 1 pipe part 8 and does not protrude from the surface of the first pipe part 8. When the first pipe portion 8 is further inserted into the connecting pipe 3 in this state, as shown in FIG. 4C, the fixing pin 10 reaches the position of the through hole 7, and the fixing pin 10 biases the elastic body 9. By this, it protrudes from the through hole 7 to a predetermined length, and the connecting pipe 3 and the first pipe portion 8 are fixed.

  In order to separate the connecting pipe 3 and the first pipe part 8, the connecting pipe 3 and the first pipe part are pulled by pulling the connecting pipe 3 while the fixing pin 10 is pushed inside the first pipe part 8 with a finger. 8 can be separated.

  Next, the connection between the third pipe part 11 of the small suction tool 5 and the second pipe part 16 of the floor suction tool 6 will be described.

  As shown in FIG. 7, when the second pipe part 16 of the floor suction tool 6 is inserted into the third pipe part 11 of the small suction tool 5, the second claw part 14 of the small suction tool 5 is second locked. The first claw portion 25 provided on the upper surface of the portion 18 is pushed, and the second locking portion 18 is rotated around the shaft body 22. When the second pipe portion 16 is further inserted into the third pipe portion 11 in this state, the second claw portion 14 of the small suction tool 5 gets over the first claw portion 25 of the third pipe portion 11, and the second pipe portion 16. And the third pipe portion 11 are locked.

  At this time, as shown in FIGS. 5 and 7, a part of the main body portion 21 of the second locking portion 18 is inserted inside the dust removing portion 12 of the small suction tool 5. The side surface of the main body 21 inserted into the inner side of 12 is substantially abutted on the rib 15 so as to be sandwiched between the ribs 15 provided inside the dust removing unit 12.

  Further, at this time, as shown in FIGS. 7C and 8, the tip of the third pipe portion 11 is brought into substantially contact with the wall portion 17 of the second pipe portion 16.

  In order to separate the floor suction tool 6 and the small suction tool 5 from each other, the pedal portion 20 of the second locking portion 18 is pushed to cause the first claw portion 25 of the second locking portion 18 to The floor suction tool 6 and the small suction tool 5 can be separated by removing from the second claw portion 14 and pulling the small suction tool 5 in this state.

  The dimension of the outer shape of the second pipe part 16 of the floor suction tool 6 and the dimension of the inner diameter of the other end 4 of the connecting pipe 3 are such that the second pipe part 16 and the connecting pipe 3 can be taper-fitted. It is configured. For this reason, in the state which removed the small suction tool 5 from the connection pipe 3 and the floor suction tool 6, by inserting the other end 4 of the connection pipe 3 in the 2nd pipe part 16, the 2nd pipe part 16 and a connection pipe 3 can be connected. At this time, the other end 4 of the connecting pipe 3 is substantially in contact with the wall portion 17 of the second pipe portion 16.

  About the vacuum cleaner comprised as mentioned above, the operation | movement is demonstrated below.

  When the user performs normal floor cleaning, the user connects the hose 2, the connecting pipe 3, the small suction tool 5, and the floor suction tool 6 to the cleaner body 1. In this state, when the user turns on the electric vacuum cleaner 100, an electric blower (not shown) in the cleaner main body 1 operates, and from the suction opening provided on the bottom surface of the floor suction tool 6. Dust on the floor is inhaled. Dust sucked from the floor suction tool 6 is collected by a dust collection chamber (not shown) provided in the cleaner body 1 via the small suction tool 5, the connecting pipe 3, and the hose 2.

  When the user cleans a narrow part such as a gap in furniture, the user pushes the bedal part 20 of the second locking part 18 of the floor suction tool 6 with his / her hand or foot, and makes the floor suction tool 6 small. It can be removed from the suction tool 5 and a small suction tool 5 can be used to clean a narrow part such as a gap in furniture. Further, since the brush 13 is provided at the edge of the tip of the dust removing portion 12 of the small suction tool 5, the user can use the brush 13 to scrape dust in a narrow part such as a gap in furniture. It is possible to suck from the third pipe portion 11 of the small suction tool 5.

  With this configuration, since the user can simplify the operation of replacing the suction tool, the cleaning efficiency can be greatly improved.

  Further, since the connecting pipe 3 and the first pipe portion 8 of the small suction tool 5 are fixed by the through hole 7 and the fixing pin 10, the user can remove the floor suction tool 6 from the small suction tool 5. By pulling the connecting pipe 3, the connecting pipe 3 and the first pipe portion 8 of the small suction tool 5 are not separated from each other, and it becomes easy to use.

  In the case of adopting such a configuration, it is necessary to fix each of the connection pipe 3 and the small suction tool 5 and between the small suction tool 5 and the floor suction tool 6. Because the fixed configuration becomes an obstacle, attachments other than the dedicated small suction tool cannot be connected to the connecting pipe 3, or cleaning components other than the dedicated small suction tool 5 cannot be connected to the floor suction tool 6. The versatility tended to get worse.

  However, in the electric vacuum cleaner of the present embodiment, the other end 4 of the connecting pipe 3 has no connection structure and is a complete pipe shape. Therefore, the small suction tool 5 and the floor suction of the vacuum cleaner of the present embodiment. It is possible to connect not only the tool 6 but also a suction tool attached to other vacuum cleaners and a general cleaning attachment and suction tool that are commercially available by taper fitting, and is highly versatile. It will be a thing.

  Also, the floor suction tool 6 has a perfect pipe shape without a fixing structure for fixing the second pipe portion 16 to the small suction tool 5, a shape of a rotation stopper, and a structure for suppressing rattling. It can be connected to the attachment of the vacuum cleaner according to the embodiment by taper fitting, and is highly versatile.

Furthermore, in the vacuum cleaner of the present embodiment, the mechanism for preventing rotation between the floor suction tool 6 and the small suction tool 5 is provided inside the tip of the dust removing portion 12 of the small suction tool 5. The appearance of the floor suction tool 6 is not affected. Similarly, the configuration that suppresses rattling between the floor suction tool 6 and the small suction tool 5 uses the wall 17 of the second pipe portion 16 and does not affect the appearance of the floor suction tool 6. With such a configuration, when the floor suction tool 6 is viewed as a single item, it is configured so that an unnecessary shape is not exposed to the outside as much as possible, and therefore, it can be easily used for attachment of a vacuum cleaner other than the present embodiment. .

  Further, in order to make the second pipe portion 16 into a complete pipe shape, it is necessary to separate the fixing mechanism of the small suction tool 5, but at that time, the floor suction tool 6 and the small suction tool 5 are also required. Is separated from the pipe portion which is a fixed shaft between the small suction tool 5 and the floor suction tool 6. As a result, the first claw portion 25 and the second claw portion 14 are likely to be inclined due to the backlash of the second pipe portion 16 and the third pipe portion 11, and the first claw portion 25 and the second claw portion 14 that are separated from the pipe. The contact surface is likely to come off, and as a result, it becomes easy to come off when the floor suction tool 6 and the small suction tool 5 are connected in a messy manner such as swinging.

  However, in the electric vacuum cleaner of the present embodiment, the angles α and β with respect to the axial direction of the pipe of the contact surfaces of the second claw part 14 and the first claw part 25 are both acute angles. Even if there is messy handling such as swinging in a state where the suction tool 6 and the small suction tool 5 are connected, the claw fitting does not come off due to some backlash between the second pipe portion 16 and the third pipe portion 11. It is possible to provide a user-friendly and safe suction tool.

  The vacuum cleaner of the present invention makes it easy to clean the gaps in the room with a small suction tool, and the connecting pipe and the floor suction tool constituting the vacuum cleaner can have a highly versatile configuration. It can be suitably applied to the fields and uses of electric vacuum cleaners for business use.
