Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of quickly dehydrating a rain-wet umbrella.

[0002]

2. Description of the Related Art Hitherto, various types of drainers have been proposed for quickly dehydrating an umbrella wet with rain. This is to remove water droplets from the umbrella at the entrance in order to solve various problems that occur when a wet umbrella is brought into a building, and dehydrate it to a state where water does not drip.

As a method of dehydration, there is a method of blowing water drops by blowing air. However, although this method has some effect with a new umbrella having a waterproof effect, it does not have an effect with a vinyl umbrella which has been widely spread as a simple umbrella recently. This is because the water droplets are widely dispersed in the form of a water film and cannot be ejected.

Therefore, Japanese Utility Model Application Laid-Open No. 3-107695 discloses a method of sucking water droplets.
As shown in FIG. 6, while a sponge-shaped water absorbing body 22 is installed in a frame 21 having a substantially umbrella-like shape in a housing 20,
The housing 20 is provided with a suction fan 25 so that the inside of the housing 20 can be made to have a negative pressure.

The umbrella 23 is pressed against the water absorbent body 22 for use. The water absorbing body 22 has a slit 24.
Is provided, and when the fan 25 is operated, the inside of the housing 20 becomes a negative pressure, and the water droplets of the umbrella are sucked into the housing 20 from the slit 24.

[0006]

However, in the above-mentioned conventional one, since the frame 21 has a fixed shape, it does not come into close contact with the umbrella 23 having various shapes, and the frame 2
Even if the deformation of the water absorbing body 22 between the 1 and the umbrella 23 is taken into consideration, the adhesiveness cannot be expected. For this reason, even if an attempt is made to suck water from the water absorbing body 22, air will be sucked in, and dehydration is difficult. In particular, since there is a concave portion between the bones of the umbrella that draws a curve that is the opposite of the curve of the entire umbrella cloth, this portion floats up without adhering to the water absorbent body 22, making it almost impossible to absorb water. .

Further, since the sponge used as the water absorbent body 22 lacks in water absorbency, the slit 24 is provided as a supplement to this, but a large amount of air is sucked from this portion, and the essential water droplets. Is not removed. In particular, there is a problem that a dehydration effect cannot be expected with a vinyl umbrella.

The present invention has been made in view of the above matters, and provides a dewatering device for an umbrella, which can effectively dewater water droplets attached to the umbrella of any material and shape. This is a technical issue.

[0009]

In order to solve the above technical problems, the present invention has the following constitution. That is, in the first configuration, there is airtightness and the opening 10 is formed on one side surface.
A housing 1 having the above, a deformable water absorbent cloth 2 stretched over the opening 10, and an air intake portion 3 provided in the housing 1 for discharging the air in the housing 1.

Here, the casing 1 is required to have a strength to withstand a negative pressure inside. Then, when the umbrella 4 is pressed against the water absorbing cloth 2, the water absorbing cloth 2 absorbs the water, and the water is discharged to the outside of the housing 1 by the air intake section 3.

It should be noted that at the center of the water absorbent cloth 2, there can be provided a tubular portion 6 into which the boss 5 of the umbrella 4 is fitted. The tubular portion 6 may be a pipe having a bottom made of metal or synthetic resin.

Further, the umbrella 4 is provided at the center of the water absorbent cloth 2.
It is possible to provide a mesh 6 through which the piers 5 can penetrate. It is desirable that the mesh 6 has the same water absorbing property as the water absorbing cloth 2.

The intake unit 3 can be specifically an electric fan and has an electric fan control unit 7 for controlling the electric fan. The electric fan control unit 7 absorbs water from the umbrella 4. First to detect approach to cloth 2
Rotation speed of the electric fan according to signals from the detection unit 7, the second detection unit 8 that detects that the umbrella 4 is in close contact with the water absorbent cloth 2, and the first detection unit 7 and the second detection unit 8. And a speed control unit 9 for controlling the.

Here, the first detector 7 and the second detector 8
Can be an infrared sensor, and the speed controller 9 can be exemplified by a thyristor chopper. The water-absorbent cloth may be any one as long as it has excellent water-absorbent property and can be expanded and contracted to be deformed, and a water-absorbent acrylic fiber woven by jersey can be exemplified.

[0015]

In the first structure, the air provided in the housing 1 is discharged by operating the intake portion 3. On the other hand, since the water absorbent cloth 2 having elasticity and water absorbability is stretched over the opening portion 10 of the housing 1, the umbrella 4 is pressed against the water absorbent cloth 2 so that the umbrella 4 and the water absorbent cloth 2 are in good contact with each other.
Due to this close contact, the moisture of the umbrella is absorbed by the water absorbing cloth 2 side by the capillary phenomenon. Since the water absorbent cloth 2 is highly stretchable and deforms in accordance with the shape of the umbrella, even if a curved surface is formed between the bones, the adhesion is good and the water is efficiently absorbed. Can be aspirated. The sucked water passes through the intake section 3 and is discharged to the outside.

In the second structure, since the cylindrical portion 6 into which the boss 5 of the umbrella 4 is fitted is provided in the central portion of the water absorbent cloth 2, the positioning of the umbrella 4 becomes easier. Furthermore, the third
In the above configuration, since the mesh 6 through which the protrusions 5 of the umbrella 4 can penetrate is provided in the central portion of the water absorbent cloth 2, the umbrella 4 can be fixed even if the umbrella 4 is slightly displaced.

In the fourth structure, the electric fan control unit 7 controls the rotation speed of the electric fan, and the first detecting unit 8 detects that the umbrella 4 has approached the water absorbing cloth 2, Since the detection unit 8 detects that the umbrella 4 is in close contact with the water absorbent cloth 2, for example, it is possible to adjust the suction force of the intake unit 3 so that the umbrella is not rapidly sucked and a shock is not generated.
