DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for dehydrating a wet umbrella in a few seconds, and more particularly to an apparatus installed at an entrance of a place such as a store, a station, or various facilities where a large number of people enter and exit, and is effective for preventing water from getting wet in the place. It relates to an umbrella dewatering device.

[0002]

2. Description of the Related Art When a person who comes from the outside with an umbrella enters a room on a rainy day, rain drops fall from the wet umbrella and wet the floor. In places such as stores with a lot of traffic, people are flooded and not only look bad, but they may fall and injure people. Therefore, bags such as polyethylene and vinyl are often prepared, but these are often disposable,
It is not preferable from the viewpoint of environmental destruction such as resource saving and waste disposal after use. In the past, in view of this point, air was blown on a wet umbrella to blow off moisture, vacuum suction, brush wiping, hot air drying, vibration and centrifugal dehydration Various types of dehydrators have been devised, but none of them are practically satisfactory, such as insufficient dehydration function or time-consuming dehydration. Incidentally, Japanese Patent Application Laid-Open Nos. 62-134479 and 63-243675 have been proposed and publicly known as a method for sucking and removing the moisture of a wet umbrella. The former is hung from the upper part so as to cover the entire umbrella in a state in which a number of water-absorbing nozzles are kept open, and because the wet umbrella is approached to the nozzle with the umbrella kept open to suck and remove water droplets. In addition, the size of the apparatus itself is increased, and the dewatering effect cannot be obtained unless the distance between the nozzle and the umbrella is appropriate. That is, if the distance is too long, the suction force becomes weak, and if the distance is too close, a wet cloth sticks to the nozzle opening, and a sufficient dewatering effect cannot be obtained. The latter has a double cylindrical water droplet suction device, and the suction device has a large number of holes in the inner cylinder, and when the wet umbrella is inserted into the inner cylinder, the outer cylinder is inserted. A negative pressure is applied between the inner cylinder and the inner cylinder, and water droplets are sucked through the pores to perform a dehydration function. However, with this device, it is difficult to sufficiently dehydrate the moisture of the cloth part that is crushed and overlapped and folded, and the wet cloth on the inner cylinder surface with the suction hole sticks to the surface with suction as it is suctioned. I couldn't get the dehydration effect as I expected.

[0003]

SUMMARY OF THE INVENTION The present invention solves these problems of the prior art, and provides a novel suction type wet umbrella dehydrating apparatus which has an excellent dehydrating function and can perform necessary dehydrating in a short time. is there.

[0004]

A wet umbrella dewatering apparatus according to the present invention comprises a chamber connected to a negative pressure supply source and a water receiving tank, and a plurality of brushes which are connected and fixed at one end to the chamber and extend outward in a brush shape. A water suction type wet umbrella dehydrating device comprising: a nozzle having a hardness enough to penetrate the folded portion of the wet umbrella and having a degree of bending deformation without damaging the umbrella when the umbrella abuts. The opening is formed with a gap so that the wet umbrella does not stick.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The origin of the idea of the present invention is that, in view of the problem of the conventional water absorption system, it is possible to dehydrate from a cloth portion folded between umbrella bones without being large, and to avoid cloth stretching by suction. Developed with what you can do. The wet umbrella dewatering device of the present invention employs a configuration in which the wet umbrella is dehydrated in a state where the wet umbrella is pressed down so that the device does not become large. The problem that dehydration becomes difficult is devised so that dehydration can be performed efficiently by providing a plurality of nozzles in a brush shape so that a water suction port is provided in the nozzle and the tip of the nozzle reaches the folded portion. One end of the brush-shaped nozzle is connected and fixed to a chamber connected to the negative pressure supply source and the water receiving tank, and is implanted as far as possible so as to contact at least the entire circumference around the axis of the closed umbrella. The nozzle is made of a material such as a soft synthetic resin having hardness enough to penetrate the folded part of the wet umbrella and elastic enough to bend and deform without damaging the umbrella when the umbrella abuts. This moderate elasticity combines hardness that allows the nozzle to penetrate into the folded portion between the umbrella bones, and softness that does not hinder the movement of the umbrella when in contact with the umbrella and does not damage the upholstery. Also, as a solution to the problem that the wet upholstery cloth sticks to the opening during suction, the nozzle opening is provided not in the flat part but in the uneven part, so that the gap between the opening and the cloth is also sure during suction. It is devised to be formed in.

The wet umbrella dewatering device of the present invention has such a basic structure. When an umbrella wet with rain is inserted into the housing, a negative pressure supply source such as a suction pump is provided by some means. When the decompression inside the housing is started and the brush-shaped nozzle is configured to be able to contact the entire outer circumference of the umbrella, the nozzle has a moderate elasticity. The nozzle hits the umbrella bone and bends and the nozzle penetrates into the folded cloth between the umbrella bone. Therefore, according to the present invention, the nozzle can uniformly contact not only the outer peripheral surface of the umbrella but also the folded cloth portion, and the water near the umbrella cloth contacting any of the nozzles is suctioned and dehydrated by decompression of the housing. At this time, if the umbrella is rotated in the axial direction and makes contact with the brush, the nozzle enters the folded portion more effectively, and the brush-like nozzle slides over the surface of the upholstery with the movement and the vicinity Suction dehydration. In addition, since the opening of the nozzle adopts a gap formation structure, even when wet cloth is sucked, the cloth does not completely cover the opening and sticks, and always sucks moisture with air through the gap. Operation can be secured. By this operation, moisture contained in the fabric is suctioned and dehydrated almost uniformly and efficiently regardless of the position of the fabric, and the squeezed water is separated into gas and liquid and stored in a water receiving tank connected to the housing. After the water is squeezed, the operation of the suction pump is stopped and the umbrella is removed. This operation may be such that the suction pump is turned off in conjunction with the removal of the umbrella.

Embodiment 1 FIG. 1 shows an embodiment of the present invention. A is a diagram showing the basic configuration in a disassembled state, B is a diagram schematically showing a dehydration situation in the chamber portion when a wet umbrella is inserted, and C
Shows the overall configuration of the apparatus. The chamber 1 is formed in an annular shape so as to surround the outer periphery of the umbrella in the axial direction when a wet umbrella is inserted, and a large number of suction nozzles 2 are implanted on the inner surface of the annular shape in the centripetal direction. An exhaust port 11 is provided in the chamber 1 and connected to the suction pump 3 to function as a decompression chamber. A funnel-shaped drain port 12 is formed at the bottom of the chamber 1, and the drain port is connected to the water receiving tank 4. The water receiving tank 4 is provided with a drain cock 41, and if the place where the device is installed is a place where drainage is possible,
The cock 41 is opened as it is to drain the water. Otherwise, the water is introduced to a suitable place from the cock 41 by a hose or piping system. The suction nozzle 2 is made of a flexible tube made of a soft synthetic resin material having appropriate elasticity such as Teflon. The moderate elasticity has both softness that can be bent and deformed following the movement of the umbrella and hardness that can enter the folded portion of the upholstery between the umbrella bones. In this embodiment, as shown in FIG.
The umbrella is not inclined horizontally but is provided on the upper surface so that the umbrella can be easily inserted, rotated and pulled out. Further, as shown by a broken line, it is also possible to provide a plurality of such devices instead of a single unit. In that case, it is also possible to share the suction pump 3 or the water receiving tank 4 without separately providing them. The operation of the suction pump 3 may be performed manually, but a switch lever similar to the nozzle is installed, and the lever is pushed down by inserting a wet umbrella to turn on the switch. After a predetermined time by a timer, the switch is turned off. Let
It is also possible to adopt a configuration in which the lever is returned by pulling out the umbrella.

The present invention has one feature in that the opening of the suction nozzle 2 is formed with a gap so as to prevent the wet umbrella from sticking to the nozzle opening during suction. Are shown in FIGS. In Embodiment A, the tip of the nozzle is cut in a V-shape, B is an opening in the vicinity of the tube in addition to the opening at the tip, and projections are provided before and after the opening, and the form shown in C is The distal end of the tube is closed, and openings and protrusions are arranged in a checkered pattern on the tube surface near the distal end. In Embodiment D, a spherical net cap is connected to the open end of the tube, and in E, a plurality of flanges are disposed near the distal end of the tube, and openings are provided between and between the flanges. Things.
In addition, this flange may not be divided into a plurality, but may be a series of spiral bodies. Embodiment F shows an example in which a plate piece is installed in the shape of an arrow near the distal end portion of a tube, and a slit-shaped opening is provided between the plate pieces. These are similar in that they have the function of preventing the wet umbrella from sticking during suction,
There is a difference in characteristics between those having an effect of dewatering by entering the folded portion and those having an effect of widely dewatering by sliding the cloth surface, and is not limited to this embodiment. However, in designing, a more effective device can be realized if all nozzles are not unified to one type but are appropriately combined and used.

[0009]

Embodiment 2 An embodiment shown in FIG. 3 shows another embodiment, in which an annular chamber 1 directly formed by a housing 5 is used to cover the entire upholstery portion from the tip of the umbrella to the handle. It is formed of a tubular body that wraps around, and a large number of suction nozzles are implanted in a centripetal brush shape over the entire inner surface of the inner cylinder. The outer cylinder portion of the housing 5 extends further below the bottom portion of the inner cylinder that receives the stone protrusion, and the lower end portion becomes a flat surface in the stand portion 51 of the apparatus, and the space between the inner cylinder bottom portion and the lower end portion. Is a water receiving tank 4. An exhaust port 11 is provided in the chamber 1 formed by the outer cylinder and the inner cylinder, and the exhaust port 11 is connected to the suction pump 3.
Operates, the chamber 1 becomes a reduced pressure chamber. When the pressure in the chamber becomes negative, the suction nozzle 2 sucks and dehydrates water such as water droplets near the portion where the wet umbrella comes into contact, as in the previous embodiment. The structure for forming the gap in the nozzle opening may be appropriately selected from those shown in FIG. 2 in terms of design. In this embodiment, the operation of the suction pump can be arranged such that a pressure responsive switch is provided at the bottom of the inner cylinder, and the suction pump is turned on by the inserted stone of the wet umbrella and turned off by the timer.

[0010]

Embodiment 3 FIG. 4 shows a further embodiment in which the decompression chamber 1 is arranged on the left and right sides separately, wherein A is a perspective view showing the entire structure, and B is a plan view seen from above. It is. The left and right chambers 1 each have a fan-shaped cross section and have the length of the upholstery portion extending from the tip of the umbrella to the handle. A large number of suction nozzles 2 are provided on the confronting inner fan surfaces in a state where the umbrella is sandwiched between the two chambers in the axial direction of the umbrella. The wet umbrella is sandwiched between both chambers of the present apparatus, and the suction pump 3 is operated by an appropriate means to reduce the pressure in the chamber. This may be performed manually or may be performed by detecting the presence of an umbrella. Along with this, the suction nozzle 2 sucks and dehydrates water from the vicinity of the wet umbrella portion in contact, but since a large number of suction nozzles 2 having appropriate elasticity are planted facing the axis of the umbrella, The nozzle also reaches the part of the cloth folded between the umbrella bones and performs a dehydration function. However, in this embodiment, since the nozzle is difficult to reach in a direction not sandwiched by the chamber, it is important to rotate the umbrella so that the suction nozzles 2 come into contact all over the umbrella upholstery. . The water in both chambers 1 sucked together with the air is dripped below the chambers, and is guided to a water receiving tank 4 housed together with the suction pump 3 in a housing 5 space provided behind one of the chambers 1. The cross-sectional shape of this embodiment is not limited to a sector shape, but the point is that the inner surface may be formed into a curved surface so as to surround the umbrella.

[0011]

Embodiment 4 The example shown in FIG. 5 is a modification of the example shown in FIG. As shown in FIG. 5, the chambers on both sides are not fan-shaped in cross section but rectangular, and the brush-shaped suction nozzles are different from the previous ones in that they are uniformly implanted toward the facing surface. Can be configured in substantially the same manner. The wet umbrella is suction-dehydrated by a suction nozzle while passing between the two opposing chambers. A person with an umbrella can slide and dry the umbrella while walking, without having to stop. However, also in this case, since the suction nozzle is not oriented in the sliding direction, it is important to rotate the umbrella even in this example in order to uniformly dehydrate the wet umbrella. It should be noted that the arrangement of the suction pump 3 and the water receiving tank 4 extends in the sliding direction rather than behind one of the chambers, thereby realizing a thin device.

[0012]

The present invention can dewater the wet umbrella in a closed state, so that the apparatus can be reduced in size as compared with the apparatus in which the water is dehydrated in a spread state, and a large number of brushes can be planted. By adopting a method of sucking with a suction nozzle, it is possible to sufficiently dewater the folded upholstery portion despite the dewatering device of the wet umbrella in a collapsed state. That is, by forming the suction nozzle from a material having an appropriate elasticity, the suction nozzle can be deformed following the movement of the umbrella without being hurt by the movement of the umbrella. Of the umbrella can be surely penetrated, and the suction dehydration can be performed uniformly over the entire umbrella upholstery.

Further, a gap forming structure is employed so that a wet umbrella does not stick to the opening of the suction nozzle.
At the time of suction, a secure gap is ensured between the nozzle opening and the upholstery of the wet umbrella, so that moisture is sucked together with air and efficient suction and dehydration can be performed. Further, a more effective dewatering effect can be obtained by appropriately employing and combining suction nozzles having a gap forming structure with different characteristics.
