Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner with an attached nozzle, such as a shelf nozzle.

BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for vacuum cleaners whose accessory parts, such as shelf nozzles, can be easily used during cleaning.

Conventionally, for example, when a nozzle other than a floor nozzle (shelf nozzle, gap nozzle) is placed on the main body of a moving floor vacuum cleaner, a storage section provided above the main body 31 is used as shown in FIG. 32, a shelf nozzle 33 and a gap nozzle 34
A storage lid 35 is arranged so as to cover the storage part 32 and can be opened and closed, or a gap nozzle 43 is installed on a holder 42 provided on an extension pipe 41 as shown in FIG. In some cases, it was common to attach them.

Problems to be Solved by the Invention In the vacuum cleaner shown in FIG.
The accessories are always stored in the main body 31, so even if you are cleaning the floor and want to clean the top of the sofa or furniture, you can remove the extension tube from the vacuum hose and remove it from the vacuum cleaner main body 31. It was a hassle to go back to the place, take out the shelf nozzle 33, go back to the place you want to clean, and start cleaning.

In addition, in the vacuum cleaner shown in FIG. 6, the gap nozzle 43 is attached to the extension tube 41, or when actually cleaning, the extension tube 41 is often removed and attached directly to the hose.
In the end, I had to temporarily put the thing I used to clean the floor somewhere else.

The present invention has been made to solve the above problems, and aims to provide a vacuum cleaner that can be cleaned quickly without having to remove the extension tube when using the attached suction tool in the middle of cleaning. do.

Means for Solving the Problems In order to achieve the above object, the present invention provides an opening on the side of the ventilation pipe of the tip pipe provided at the end of the hose, and makes the opening slidable. An opening/closing pipe that opens and closes is arranged, and this opening/closing pipe is provided with a telescopic hose and a nozzle such as a shelf nozzle. The second means is
A telescopic hose and a shelf nosle are arranged in the middle of a ventilation pipe of a tip pipe provided at the end of the hose, and the suction port of the shelf nostle is detachably attached to the ventilation pipe.

Function The present invention has the structure of the first means described above, and when cleaning a part of a sofa etc. while cleaning the floor etc., the opening/closing pipe is slid and communicated with the ventilation pipe of the tip pipe, so that the extension can be extended. You can quickly clean the sofa with the shelf nozzle without removing the pipes, etc. Also, when using the shelf nozzle, you can use the floor nozzle via the extension pipe connected to the tip pipe. Since the suction is also carried out from the side, all the suction force is not applied to the shelf nozzle, so there is no need to adjust the suction force with a switch or the like.

In addition, with the configuration of the second means, when the shelf nozzle communicates with the ventilation pipe of the tip pipe, dust sucked from the floor nozzle, etc. passes through the shelf nozzle and the expandable hose and is collected in the main body. Therefore, even though a shelf nozzle is attached to the tip pipe, the tip pipe does not become large.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 to 3. As shown in the figure, 1 is a main body of a vacuum cleaner having a dust collection chamber inside, a hose 3 is attached to the front part of the vacuum cleaner via a connecting pipe 2, and a tip pipe 4 is provided at the other end of the hose 3. It is being And the tip pipe 4
An extension pipe 5 is connected to the extension pipe 5, and a floor nozzle 6 for sucking dust is provided at the end of the extension pipe 5, which communicates with the main body 1 of the vacuum cleaner.

Further, a retractable hose 8 and a shelf nozzle 9 are attached to the tip pipe 4 through an opening/closing pipe 7 so as to be able to freely slide on the tip pipe 4.

The tip pipe 4 has a ventilation pipe 1 for sucking dust.
0 is provided integrally, and an opening 11 is provided in a part thereof. An opening/closing vibrator 7 is placed above the opening 11 and is slidable in the direction of the arrow.
and the center line a of the opening/closing vibrator 7.

Further, a telescopic hose 8 and a shelf nozzle 9 are attached to the opening/closing pipe 7, and the shelf nozzle 9 is held by a holder 12 provided on the extension pipe 5.

In the above configuration, the ventilation pipe 10 and The opening/closing vibrator 7 communicates with each other to form an air path indicated by an arrow C. As a result, the shelf nozzle 9 can be used to clean the sofa, etc. even with the floor nozzle 6 and the extension tube 5 attached, and the room can be cleaned more efficiently.

Next, a second embodiment will be described with reference to FIG. As shown in the figure, a telescopic hose 22 and a shelf nozzle 23 are connected to the middle of a ventilation pipe 21 that is integrated with the tip pipe 20, and the suction port 23 of this shelf nozzle 23 is connected to the end surface of the ventilation pipe 21. When the suction port 24 is connected to the ventilation pipe 21, the dust sucked by the floor nostle passes through the extension pipe 25, and then passes through the ventilation pipe 21 to the shelf. Nozzle 23 and telescopic hose 22
It passes through and is sucked into the vacuum cleaner body. Then, by removing the shelf nozzle 23 from the ventilation pipe 21,
The suction force from the floor nozzle is cut off, making it possible to clean sofas and the like even with the floor nozzle and extension pipe 25 attached, allowing for efficient cleaning as in the first embodiment. Since the shelf nozzle 23 is sometimes used as a normal ventilation pipe 21, the appearance will not be significantly larger than before even if the shelf nozzle 23 is attached.

In addition, in both embodiments, by arranging the shelf nozzles 9 and 23 on the tip pipes 4 and 20, respectively, the space that was conventionally placed on the main body is no longer needed, so it is possible to downsize the vacuum cleaner main body. It is something.

As described above, according to the vacuum cleaner of the first embodiment of the present invention,
Since the extensible hose 8 and the shelf nozzle 9 are integrally provided on the end pipe 4 of the hose 3, the extension pipe 5 and floor nozzle 6 must be removed each time when cleaning a sofa or the like. There is no need to attach the holder 9, and shelves and sofas can be easily cleaned even while cleaning the floor.

In addition, in the case where the opening/closing pipe 7 provides a ventilation path from a part of the ventilation pipe 10 to the shelf nozzle 9, even if the ventilation path is connected to the shelf nozzle 9, the suction force to the floor nozzle 6 side is also increased. Because of this, the suction force, which is normally weakened by a switch when using the shelf nozzle 9, can be used without adjustment by dispersing the suction air passage.

Furthermore, by removing the shelf nozzle 9 from the storage section of the main body 1 of the vacuum cleaner, the main body 1 can be made smaller.

Further, according to the vacuum cleaner of the second embodiment, the shelf nozzle 2
3 and the telescopic hose 22 to the ventilation pipe 2 of the tip pipe 720.
1, the distal end pipe 20 can be disposed in one piece without significantly increasing its external appearance.

Effects of the Invention As is clear from the above-mentioned embodiments, the end pipe of the hose is physically provided with a telescopic hose and a shelf nozzle, so when using the attached suction device during cleaning, the extension pipe can be used. It is possible to provide an easy-to-use vacuum cleaner that can be quickly cleaned without having to remove the vacuum cleaner.
