Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella dehydrator capable of instantly dehydrating a rain-wet umbrella and carrying the umbrella indoors without having to wet the floor surface with rainwater.

[0002]

2. Description of the Related Art As a conventional umbrella dehydrator of this type, there is, for example, a structure shown in FIG. That is, reference numeral 1 is a suction frame in which a circular concave curved surface 2 corresponding to the curved surface of the opened umbrella surface is formed, and a large number of suction passages 3 are formed in the concave curved surface 2 at close intervals. A water absorbing sheet 4 made of a sheet material having excellent water absorbing property such as cotton cloth and chamois is attached to the surface of the frame 1 on which the suction passage 3 is formed, that is, the concave curved surface. Further, each suction passage 3 provided in the suction frame 1 is communicated with a suction duct 5, and a vacuum pump 7 is installed at a terminal end of the suction duct 5. 8 is a drive motor for the vacuum pump 7, 9 is an exhaust port, and 10 and 11 are drain ports. Reference numeral 12 indicates an open umbrella, and 13 indicates the umbrella cloth.

When the wet umbrella 12 is dehydrated by the conventional umbrella dehydrator having the above structure,
First, the rain umbrella is brought into an opened state, and the surface of the umbrella cloth 13 of the opened umbrella is brought into contact with the concave curved surface 2 of the suction frame 1 and the drive motor 9 is driven. The road becomes a negative pressure, and the umbrella cloth 13 is wet due to the negative pressure action.
Is adhered to the water absorbent sheet 4, and as a result, the water on the surface of the umbrella cloth 13 is absorbed by the water absorbent sheet 4, and the rainwater attached to the umbrella cloth 13 is directly removed. The water adsorbed on the water absorbing sheet 4 is discharged from the drainage ports 10 and 11 through the suction passages 3 and the suction duct 5 by the vacuum pump 7 by suction force, and the intake air is discharged from the exhaust port 9.

[0004]

However, in the umbrella dehydrator having such a conventional structure, the shape of the suction frame 1 is
That is, the front shape of the suction surface is a concave front surface is a circle that can correspond to the umbrella shape opened, at the time of umbrella dehydration,
Structure (shape) that can absorb water on the entire surface of the opened cloth at once
Therefore, since the water absorption surface of the suction frame 1 is formed to be wide and the dehydration load is large, in order to dehydrate the umbrella at once by the entire water absorption surface, the drive motor 8 having a large output is used. Since, for example, a motor having a capacity of 1.5 to 2 KW must be used, it is inevitable to use a costly drive motor. In addition, in order to absorb water on the entire surface of the opened umbrella cloth at once, the suction frame 1 must be upsized, and a large number of suction paths 3 must be formed in the suction frame 1. The cost has increased with the increase in complexity and complexity, and in addition, the weight has increased, and improvements have been required in terms of practical use.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to meet such a demand. The shape of the suction frame is changed from the conventional circular shape to a substantially semi-circular shape to reduce the suction area in the suction frame. It is an object of the present invention to provide an umbrella dehydrator that is economical and practical by reducing the size (power saving) of the drive motor used for generating suction force and reducing the size and weight of the suction frame.

[0006]

EXAMPLES The present invention will be described in detail below with reference to the examples shown in FIGS.

Reference numeral 21 is formed as a concave curved surface corresponding to the curved surface of the opened rain umbrella 12, and its front shape is shown in FIG.
As shown in FIG.
A suction frame formed in a substantially semicircular shape to avoid
The concave curved surface of the suction frame 21 has a porous plate 24 in which a large number of suction holes 23 made of punching metal or the like are formed at close intervals, and synthetic leather, chamois, cotton cloth, etc., attached to the surface of the plate 24. The water absorbing sheet 25 is made of a sheet material having excellent water absorbing property such as.

On the back surface of the porous plate 24, there are formed ventilation passages 26 communicating with the suction ports 23.
The ventilation path 26 communicates with an exhaust duct 28 having a vacuum mechanism 27. Drain ports 29 and 30 are provided in the exhaust duct 28 and the lower part of the ventilation path, and water discharged from these drain ports is stored in a tank 31. Reference numeral 32 is a drive motor for driving the vacuum mechanism 27, 33 is a base frame of the umbrella dehydrator, and 34 is a switch incorporated in the recess 22.

The structure of this embodiment has been described above. Next, its operation will be described. As shown in FIG. 2, the umbrella 12 to be dehydrated is brought into an open state, and the water absorbing sheet 2 of the suction frame 21.
When the switch 34 is pushed by the pebbles of the umbrella 12 at the same time as it approaches the 5th surface, as a result, the drive motor 3
The vacuum mechanism 27 is driven by the operation of 2 and each suction port 23
Is negative pressure. Due to this negative pressure, the umbrella 12 approaching the water absorbent sheet 25 is adsorbed to each suction port 23 together with the water absorbent sheet 25, and as a result, a part (approximately half) of the opened umbrella cloth 13 is absorbed by the water absorbent sheet 25. To be dehydrated.

Next, the rain umbrella that has been opened is pulled slightly forward of the suction frame 21 to release the push of the switch due to the stone pebbles, and the drive motor 32 temporarily stops the drive, so that the rain umbrella is released. Rotate about 180 degrees. That is, the dehydration of the entire rain umbrella is completed by bringing approximately half of the dehydration incomplete into contact with the surface of the water absorbing sheet 25 and pushing the switch 34 with a stone butt.

As described above, in the present invention, the suction frame 21
Since the water absorption surface of is a semi-circular shape, dehydration of the umbrella cloth opened as described above is performed in approximately half steps (semi-circular portion)
Although the dehydration operation has to be repeated twice, it takes a lot of time to perform the dehydration operation, but since the water absorption surface of the suction frame is approximately semi-circular, it is about 1/2 of that of the conventional circular water absorption surface.
Therefore, the output of the drive motor 32 can be halved.

Further, since the substantially semicircular plate 24 constituting the suction frame 21 can use a porous plate 24 such as punching metal, a large number of suction passages 3 as shown in the conventional example are provided. The productivity is better and the economy is better than that of the suction frame 1 structure. Furthermore, since the suction frame 21 of this embodiment has a substantially semicircular shape,
The weight is significantly reduced compared to the conventional circular suction frame structure.

[0013]

Porous plate 24 that is made up of at least, water absorbing sheet 25 attached to the surface of porous plate 24, and porous plate 2
4 is a dehydrator for an umbrella provided with a suction frame 21 having a ventilation path 26 communicating with the vacuum mechanism 27, and according to this, the water absorption surface of the suction frame 21 is substantially semicircular. Therefore, the dehydration of the umbrella cloth opened as described above, the dehydration operation has to be repeated twice for each half (semicircular portion), but the dehydration operation is troublesome.
The water absorption surface of the suction frame has a substantially semi-circular shape, so that the dehydration load is about 1/2 of that of the conventional circular water absorption surface,
Therefore, the output of the drive motor 32 can be halved. Further, since the suction frame 21 has a substantially semi-circular shape, the weight is significantly reduced as compared with the conventional circular suction frame structure.

Further, since the substantially semicircular plate 24 constituting the suction frame 21 can be a porous plate 24 such as punching metal, a large number of suction passages 3 as shown in the conventional example are provided. It is possible to provide an umbrella dehydrator having excellent productivity and economic efficiency as compared with the suction frame 1 structure.
