Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an upright vacuum cleaner, and particularly to the shape of a duct that communicates an electric blower chamber and a dust collection chamber.

[Background of the invention]

An example of a conventional upright vacuum cleaner is the
There is No. 5-79953. In this example, the electric blower room and the dust collection room are connected by a hose that runs through the cleaner body. Therefore, when cleaning narrow spaces such as under the bed,
As shown in FIG. 7, even when the main body 11 is lowered, the hose 46 protruding outside becomes an obstacle, and there is a limit to the space that can be cleaned. Ideally, as shown in Figure 6, it is desirable that the hose can be folded down to a horizontal position.However, simply incorporating the hose into the main body will create a bent part, making it difficult to remove the hose when it becomes clogged. . Additionally, there is a demand for attaching a separate hose with a thinner nozzle to clean high places or very narrow areas, but this cannot be met.

[Purpose of the invention]

The object of the present invention is to be able to tilt the main body almost horizontally, and to
To provide an upright type electric vacuum cleaner which can be easily removed when clogged with dirt and can be connected to an adapter such as a separate hose.

[Summary of the invention]

The present invention incorporates a dust passage duct that communicates the electric blower chamber and the dust collection chamber of the vacuum cleaner body into the main body instead of the conventional external hose, and the end of this duct on the dust collection chamber side is omitted. We propose an upright vacuum cleaner that is formed in a T-shape, with one end of the approximately T-shape communicating with a dust collection filter, and the other end opening at the back of the main body, which can be opened and closed with a lid attached to the main body. .

The lid attached to the main body is normally closed. Furthermore, it is desirable that the inner surface curve smoothly toward the dust collecting filter, since this facilitates the flow of dust. This lid is opened when the duct becomes clogged with debris or when a separate hose is inserted and used.

[Embodiments of the invention]

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 6. First, FIG. 1 is a perspective view showing the appearance of an upright vacuum cleaner according to the present invention.

FIG. 2 is a longitudinal cross-sectional view of the main body cut at the center. In the figure, an opening portion 5 is provided on the lower surface of a U-shaped mouthpiece 1 close to the floor surface. Here, there are 4 flocks on the surface of the cylinder.
The rotary brush 3 formed with this is attached. A bumper 2 made of a soft material is arranged in front of the mouthpiece 1 to prevent damage even if it collides with furniture or the like. 7 is bottomless, 6 is front wheel, 9
is the rear axle, and 8 is the duct.

The rotating brush 3 is connected to the electric blower chamber 40 by a belt 43.
It is connected to the shaft 10 of the electric blower 42 inside.

Therefore, when the electric blower 42 rotates, the rotating brush 3 also rotates. The electric blower room 40 further includes a Ta movable blower 1.
There is a suction duct 39 as a passage for air to 2, and an electric blower chamber cover 41 is formed on the front side.

The dust entering through the opening 5 passes through the duct 38 and enters the dust collection filter 33 built into the dust collection chamber 37 inside the two-body case 11. The mouth part 35 of the dust collecting filter 33 is fixed to the filter holder 31 by the claw 21 and the holder holding part 36. Furthermore, filter holder 3
1 is the filter base 1 in which the RoPacking 34 is fitted.
2 is removably fixed. The filter base 12 is fixed to the screw boss 18 of the main body case 11 by a base-side boss 32.

The duct 3 has a substantially T-shaped tip 13 that branches into the filter base 12 side and the main body back side. One end of the T-shape is connected to the dust filter 33, and the other end is connected to the main body 1.
It opens at the back of 1.

As is clear from the enlarged view shown in FIG. 3, this opening can be sealed by a lid 17 that can be opened and closed about a fulcrum 19. It is desirable that the inside of the lid 17 be formed into a curved surface to facilitate the flow of dirt, and from the viewpoint of airtightness, the gasket 16 is preferably made of an elastic material such as rubber. On the other hand, the back of the main body case 11 is formed with a relief part 20 when the lid 17 is raised, a recess 46 when it is lowered, and a snap hit 15 for fixing the tip of the lid.

The dust filter 33 can be taken out from the main case 11 by removing the front cover 30. The front lid 30 is fixed to the main body case 11 by a clamp at the top that contacts the inside of the main case 11 by the elastic force of the clamp spring 27. A power cord 24 is wound around a cord reel 28 above the dust collection chamber 37, and the cord reel 28 is fixed to the main body case 11 with screws 29. Electricity is introduced from the power cord 24 through the contact piece 22 and into the reel support 23. As shown in FIG. 1, there is a main switch 44 at the top of the cord reel 28.

25 is a handle for operating the vacuum cleaner.

Now, the lid 17 of the opening formed on the back of the main case 11
This opening is sealed during cleaning and when not in use.

What's more, its inner surface is curved toward the dust collection filter, allowing for smooth flow of dust. In the unlikely event that this part of the duct becomes clogged with debris, you can easily remove it by opening the lid.

Furthermore, as shown in FIG. 5, by inserting a separate hose and attaching a thin nozzle, it becomes possible to clean narrow spaces more easily. In addition, the downside of upright Yaj (difficulty in pressing for a long time and cleaning walls, etc.) can be overcome because a long hose can be connected.

Also, as already mentioned in the comparison between Figures 6 and 7,
According to this embodiment, which realizes the ideal form of a garden, it is possible to sufficiently clean places such as under the bed, where it was difficult for the main body to enter conventionally.

〔Effect of the invention〕

According to the present invention, it is possible to obtain an upright vacuum cleaner whose main body can be laid down almost horizontally, which can easily remove clogged dirt, and which can also be connected to an adapter such as a separate hose.
