Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a suction port of a vacuum cleaner.

[0002]

2. Description of the Related Art In general, there is known a vacuum cleaner having a suction port having a dust suction opening on a lower surface and a connection port for connecting a suction hose on a side surface or an upper surface. In this type, the dust suction opening of the suction port body is directed to a carpet or a floor, and slides there to absorb dust accumulated on the carpet or the floor.

[0003]

In the conventional structure, when the dust suction opening of the suction port body is completely closed by, for example, a carpet, the pressure in the suction port body is reduced, and the suction port body is thereby reduced. There is a problem in that a considerably strong force is required to slide the suction port body by being adsorbed on the carpet.

On the other hand, as shown in Japanese Patent Application Laid-Open No. 9-28630, a rotary cleaning body is rotatably provided at a suction port of a suction port body of a conventional vacuum cleaner. A turbine formed by combining first and second turbines each having a quarter-arc shape at both ends is provided coaxially with the rotary cleaning body, and a vent is formed in an upper case or a separately provided cover to form the turbine. There is a structure in which air is supplied to the rotary cleaner to drive the rotary cleaning body.

However, in this structure, since the rotary cleaning body is attached to the suction port of the suction port main body, the manufacturing cost is increased, and the rotary cleaning body does not rotate well, causing a trouble.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to realize a suction port which can slide the suction port with a light force with a simple structure, and an electric device using the same. It is to provide a vacuum cleaner.

[0007]

According to the first aspect of the present invention,
In a suction opening body having a dust suction opening on a lower surface and a connection port for connecting a suction hose on a side surface or an upper surface, the suction opening body has a box body having a cavity. An air intake is provided.

According to a second aspect of the present invention, in the first aspect, the air intake has a plurality of circular holes, and a shutter capable of closing the circular holes is provided.

According to a third aspect of the present invention, in the first aspect, the air intake is a plurality of slit-shaped long holes, and a shutter capable of closing these long holes is provided. .

According to a fourth aspect of the present invention, there is provided an electric vacuum cleaner having a suction port having a dust suction opening on a lower surface and a connection port for connecting a suction hose on a side surface or an upper surface.
The suction port has a box having a cavity, and an air inlet is provided on a side surface or an upper surface of the box.

In the present invention, for example, even when the dust suction opening of the suction mouth body is completely closed by the carpet,
Since the air intake is provided on the side surface or the upper surface, air flows into the suction port body therefrom.

Therefore, the inside of the suction opening is not depressurized, and the suction opening is not adsorbed on, for example, a carpet. Therefore, the suction opening can be slid with a very small force.

When the suction power of the vacuum cleaner is weakened, for example, a shutter may be used to reduce the opening area of the air intake.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the vacuum cleaner of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the overall appearance of a vacuum cleaner. In FIG.
02 is a hose, 103 is a remote control switch provided on the hose hand, 104 is an extension tube, and 105 is a suction port.

When the main body of the vacuum cleaner 101 is in an operation state, the airflow sucked together with dust from the suction port body 105 enters the main body of the vacuum cleaner 101 via the extension pipe 104 and the hose 102, and the dust is collected. After being discharged. The operation of the vacuum cleaner main body 101 is controlled by a command from a remote control switch 103.

FIGS. 2 to 5 show a suction port of the vacuum cleaner according to the present invention. The suction port main body 1 has a horizontally extending box 2 and a boss formed substantially at the center of the box 2. Part 3 and a pipe 4 rotatably connected to the boss part 3
(Connection port), and the extension pipe 104
Are connected.

As shown in FIG. 5, the lower surface 2A of the box 2 has a dust suction opening 10 and a wide portion 11, and almost all of the wide portion 11 is designed to improve the slipperiness. , For example, a sliding sheet 12 or the like is stretched.

The inside of the box 2 is a large cavity 13 in which there is no conventionally known rotary cleaning body or the like. In this structure, since an extra rotary cleaning body is not attached to the suction port of the suction port main body 1, the manufacturing cost is kept low, and troubles such as the rotary cleaning body not rotating are eliminated.

However, it is desirable that the wall surface inside the cavity 13 be
A brush or rubber blade is attached to the cleaning floor so that it can freely contact the floor. It goes without saying that the cavity 11 communicates with the boss 3 and the pipe 4 rotatably connected to the boss 3.

In the present embodiment, the side surface 2B or the upper surface 2C (only the side surface 2B in the present embodiment) of the box 2 is provided.
An air inlet 21 is formed. This air intake 21
Are a plurality of circular holes, and these circular holes 21 are configured to be variable in area by a shutter 22. A hole having substantially the same diameter as the circular hole 21 is formed in the shutter 22.
The area of the shutter 22 is changed by sliding the shutter 22 in the longitudinal direction by a mechanism not shown.

The shutters 22 may be provided in all the air intakes 21 or in some of the air intakes 21.

In this embodiment, for example, even when the dust suction opening 10 of the suction port main body 1 is completely closed by a carpet, the air intake 21 is provided on the side surface 2B or the upper surface 2C. Therefore, air flows into the suction port main body 1 therefrom. Therefore, the suction port main body 1
The inside of the suction port body 1 is not depressurized,
For example, the suction port main body 1 is not adsorbed on the carpet, and thus the suction port main body 1 can be slid with a very small force during cleaning.

When the suction power of the vacuum cleaner becomes weak, for example, the opening area of the air intake 21 may be reduced by using the shutter 22.

FIG. 6 shows another embodiment.

In this embodiment, the air inlet 31 is a plurality of slit-shaped long holes. These long holes 31 are configured so that the area thereof can be freely changed by a shutter 32. In this case, the shutter 32 is slid in the short direction.

According to this embodiment, as described above,
For example, the dust suction opening 1 of the suction port main body 1 is made of a carpet.
Even when 0 is completely closed, air flows into the suction port main body 1 from the air intake 31. Therefore, the inside of the suction port main body 1 is not depressurized, and the suction port main body 1 is not adsorbed on a carpet, for example.
Therefore, at the time of cleaning, the suction port main body 1 can be slid with a very small force.

When the suction power of the vacuum cleaner is weakened, for example, the opening area of the air inlet 31 may be reduced by using the shutter 32.

FIGS. 7 and 8 show another embodiment.

After the air from the air intake 41 enters the suction port main body 1, it goes to the substantially center of the cavity 13 of the box 2.

In the embodiment shown in FIG. 7, the width dimension W of the box 2 is formed narrower from the center toward the end.
In the embodiment shown in (1), the height dimension H of the box body 2 is formed to be lower from the center to the end. Further, as shown in FIG. 9, the air intake 41 is desirably formed slightly upward.

As a result, the air taken in from the air inlet 41 and flowing substantially toward the center of the dust suction opening 10 flows smoothly.

Although the present invention has been described based on one embodiment, it is apparent that the present invention is not limited to this.

For example, the configuration of the suction port main body 1 is not limited to the above. It is desirable that the air intakes are formed on both sides of the box and are not formed at the center of the box.
This is because, if the air intake is formed in the center of the box, a uniform air flow is not formed in the entire area of the box. The shape of the air intake is, for example, rectangular, elliptical, rhombic, trapezoidal,
It goes without saying that various shapes such as triangles and polygons are applied.

[0035]

According to the present invention, for example, even if the dust suction opening of the suction port body is completely closed by a carpet, air flows into the suction port body from the air intake port. The body is not decompressed, and this suction port body is not adsorbed on a carpet, for example,
Therefore, the suction opening can be slid with extremely light force during cleaning.

If the suction power of the vacuum cleaner is weakened, it can be adjusted, for example, by sliding a shutter.
