Abstract

PROBLEM TO BE SOLVED: To effectively utilize the attachment storage space of the body at low cost by connecting the inner pipe of the extension pipe to the hose side and the outer pipe to a suction duct side and setting them to the flow passage parts to the dust collection chamber. SOLUTION: Where a hose is intended to be used with the cleaner body in a standing state, the hose joint 56 can be detached from the inner pipe fitting part A formed in an inner pipe 41. In using the extension pipe in an actually using state, the inner pipe 41 is taken out from the outer pipe 40 by just drawing out the inner pipe grip 43 upward therefrom, thus easily operated with the hose connected thereto. Where using the extension pipe in its long state, the inner pipe fitting part B of the inner pipe 41 taken out before and the outer pipe fitting part B side of the outer pipe 40 detached from the suction duct joint 51 are fitted together so as to be connected. The outer pipe fitting part A side of the outer pipe 40 has such a shape as being connectable to other attachment.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright type vacuum cleaner of an attachment (extension tube) storage type.

[0002]

2. Description of the Related Art Conventionally, upright type vacuum cleaners have been
As described in 4,959,883, the vacuum cleaner had a structure in which hoses and other accessories were stored at the back, and the extension pipe was configured as a part of the flow path component. In addition, when it is desired to use the extension pipe for a long time, the extension pipe is connected to an extension pipe located at another position.

[0003]

SUMMARY OF THE INVENTION However, USP
In the case of the structure described in 4, 959, 883, the extension pipes to be joined are arranged at different positions, so in the case of storing hoses and accessories on the back of the vacuum cleaner body, hide the extension pipes from the front Therefore, there is a problem that the internal structure of the main body is restricted to some extent, so that an effective space cannot be used even when it is arranged inside the outer peripheral surface of the main body.

[0004] It is an object of the present invention to provide a structure capable of effectively utilizing the accessory storage space of the main body at low cost.

[0005]

In order to achieve the above-mentioned object, a suction device is provided with a suction duct serving as a dust flow path, and the suction duct is positioned to a back surface of the cleaner body. An extension pipe composed of an inner pipe and an outer pipe detachable from a suction duct is arranged between a hose connected to the chamber and arranged on the back, and the inner pipe of the extension pipe is connected to the hose side, and the outer pipe is connected to the hose. It was connected to the suction duct side to form a flow path component to the dust collection chamber.

FIG. 4 shows an initial connection state. When a hose is to be used while the cleaner body is standing, the hose joint 56 is connected to the inner pipe fitting portion A44 formed on the inner pipe 41. Can be removed from. At this time, the inner pipe gripping portion 43 formed on the inner pipe 41
You can also remove it while holding down. Although the hose joint 56 has a structure in which a brush is planted in the drawing, it may be configured as a separate part.

When it is desired to use an extension pipe (about one length) in an actual use state, as shown in FIG.
The inner pipe 41 can be taken out of the outer pipe 40 only by pulling out the upper side, and the operation can be easily performed with the hose connected.

When the extension pipe is to be used in a longer state, as shown in FIG. 7, the inner pipe fitting portion B45 of the inner pipe 41 taken out earlier and the outer pipe of the outer pipe 40 removed from the suction duct joint 51 are used. The connection can be made by fitting the fitting portion B39 side.

The outer pipe 40 has such a shape that other accessories can be connected to the outer pipe fitting portion A38 side.
