Description

  The present invention relates to an umbrella dewatering device that removes water attached to an umbrella in a short time and prevents water leakage indoors when the umbrella wet with rain is brought indoors.

  In rainy weather, places where unspecified number of people gather, such as department stores, supermarkets, convenience stores, pachinko parlors, hospitals, government offices, and other commercial and public facilities, are constructed with water drops hanging from wet umbrellas held by visitors. There is a problem that the floor inside gets wet. In order to prevent this, conventionally, a plastic bag for putting an umbrella in the entrance is prepared. However, there is a problem that there are some visitors who do not use the prepared plastic bag because the operation of putting a wet umbrella in a slender bag is troublesome, and these are not effectively used. Furthermore, although used vinyl bags need to be collected and discarded, they are often not collected at a predetermined collection place and scattered in the vicinity of the entrance and are often visually dirty. In addition, used plastic bags are incinerated as garbage, but since dioxins generated during incineration have become a pollution problem in recent years, it is not easy to treat as waste, and it is not easy to recover and treat. There is a problem that it takes time and money. In particular, used plastic bags are wet without exception, which also makes it difficult to process after collection, which increases disposal costs.

  In view of these problems, an umbrella drying device that blows air to an umbrella and removes water droplets attached to the surface has been developed (see Patent Document 1). This drying device has a structure in which moisture attached to the umbrella is removed by jetting a high-speed air flow from a blower onto an umbrella inserted in a dehydration space provided on the upper side of the box. Furthermore, a drying apparatus has also been developed that partially evaporates water droplets adhering to the umbrella as warm air heated by an electric heater as the air blown on the umbrella, and leads the remainder to the water channel to approach the dry state (see Patent Document 2). ). However, these drying devices have a drawback that it takes time to remove the water adhering to the umbrella, because the air adhering to the umbrella removes the water adhering to the surface. This is because water is transferred and removed along the fabric of the umbrella by the air flow to be blown. Moreover, since these drying apparatuses transfer water with a high-speed air flow, it is necessary to increase the output of the blowing mechanism that blows air. For this reason, the running cost is increased, and the blower mechanism having a large output has a drawback that noise is increased. In particular, a device that blows warm air needs to energize the electric heater, which further increases the running cost.

  Furthermore, an umbrella dewatering device has been developed that sucks and removes water droplets adhering to the surface of the umbrella with a suction mechanism (see Patent Documents 3 and 4). In these dewatering devices, a plurality of brushes are disposed on the inner wall of the umbrella housing portion, and a blower is connected to the umbrella housing portion. These dewatering devices have a structure in which water attached to the surface of the umbrella is sucked and removed by sucking with a blower in a state where a plurality of brushes are in contact with the surface of the cloth of the umbrella inserted into the umbrella housing portion. However, these dewatering devices suck the water adhering to the surface of the umbrella directly with the blower, so it is necessary to increase the suction force of the blower, and there is a drawback that a large noise is generated and the running cost is increased. . There is also a drawback that it takes time to suck the water droplets of the entire umbrella.

  Furthermore, for the purpose of increasing the dewatering efficiency of the umbrella, a dewatering device has been developed in which a sponge material that absorbs water adhering to the umbrella is disposed in the umbrella housing portion (see Patent Documents 5 and 6).

  In the dehydrating apparatus described in Patent Document 5, a sponge material is disposed inside the umbrella receptacle, and the umbrella receptacle is hermetically sealed and sucked with an air suction device to contract the umbrella receptacle so that the sponge material is used. It is made into the structure which removes the water of the umbrella surface by sticking to the umbrella.

  However, the dehydrating device with this structure has a drawback that the structure of the entire device is complicated because the umbrella receiving tube needs to be hermetically sealed in order to suck and shrink the umbrella receiving tube with an air suction device. . Further, since the lid is provided to hermetically seal the umbrella receiving tube, it is necessary to open and close the lid every time the umbrella is taken in and out, and this operation is troublesome. Furthermore, this dewatering device absorbs moisture adhering to the surface of the fabric by adhering the sponge material to the surface of the umbrella which is in a thin and closed state, so that the moisture adhering to the overlapping portion of the fabric cannot be sufficiently absorbed There is.

  Further, the dehydrating apparatus of Patent Document 6 has a pair of sponge materials attached to an opening / closing mechanism in combination so as to be capable of opening / closing, contracting and expanding, and closing the opening / closing mechanism with an umbrella inserted between the pair of sponge materials, The sponge material is compressed to discharge moisture contained in the sponge material. This dehydrator absorbs the moisture of the umbrella in the sponge material from which the moisture has been discharged in a state where the compression of the sponge material is released.

  However, since this dehydrating device opens and closes by reciprocating a pair of sponge materials with an opening and closing mechanism, there is a drawback that this opening and closing mechanism becomes complicated. Furthermore, this dewatering device has a drawback that it cannot sufficiently absorb the moisture adhering to the overlapping portion of the fabric because the closed umbrella is sandwiched between sponge materials. Furthermore, since this dehydrator compresses the sponge material and squeezes out the moisture contained in the sponge material while the umbrella is sandwiched between a pair of sponge materials, the entire umbrella is also compressed with the sponge material. However, the state in which the entire umbrella is sandwiched between sponge materials is not necessarily a good state for the umbrella. The reason is that there is a risk that the umbrella bone and the middle stick may be damaged or deformed by the sandwiched pressure. This problem can be eliminated by reducing the pressure for sandwiching the sponge material. However, if the force for compressing the sponge material is reduced, the moisture contained in the sponge material cannot be sufficiently discharged, and the efficiency of absorbing the moisture on the surface of the umbrella decreases.

  The present invention has been developed to solve the above problems. An important object of the present invention is to provide an umbrella dewatering device capable of reliably removing moisture adhering to an umbrella in a short time while reducing the running cost as a simple structure.

  The umbrella dewatering device according to the present invention includes an umbrella receiver 1 having an opening 10 into which the umbrella 30 is inserted, and absorption that is disposed on the inner surface of the umbrella receiver 1 and absorbs water adhering to the surface of the umbrella 30. A material 2 and a suction machine 3 for sucking water absorbed by the absorbent material 2 are provided. The absorbent material 2 has water absorption and cushioning properties. The umbrella dehydrating device reduces the volume of the absorbent material 2 by bringing the fabric 31 of the umbrella 30 into close contact with the inner surface of the absorbent material 2 while the suction device 3 is in the suction state, and sucks moisture contained in the absorbent material 2. 3, the suction device 3 is in a suction stop state, the absorbent material 2 is restored to its original volume, and the water adhering to the surface of the fabric 31 of the umbrella 30 is absorbed.

  In the umbrella dehydrating apparatus of the present invention, the absorbent material 2 can be a soft synthetic resin foam having open cells.

  In the umbrella dewatering device according to the present invention, the shape of the inner surface of the umbrella housing portion 4 can be tapered so that the umbrella 30 in a closed state can be inserted.

  The umbrella dehydrating apparatus according to the present invention has a dual structure in which the umbrella receiver 1 is composed of an inner container 11 and an outer container 12, and a suction duct 13 is provided between the inner container 11 and the outer container 12. Is connected to the suction device 3 and a plurality of suction holes 6 are opened in the inner container 11 so that moisture contained in the absorbent 2 can be sucked through the suction holes 6 of the inner container 11 through the suction duct 13. it can.

  The umbrella dewatering device according to the present invention has a simple structure and has a feature that the running cost is reduced and moisture attached to the umbrella can be reliably removed in a short time. The umbrella dewatering device of the present invention is an absorbent material that absorbs water adhering to the surface of the umbrella, and an absorbent material having water absorption and cushioning properties is disposed on the inner surface of the umbrella receptacle to absorb the water. It is structured to suck water absorbed by the material with a suction machine, the suction machine is in a suction state, the umbrella fabric is brought into close contact with the inner surface of the absorbent material to reduce the volume of the absorbent material, and is included in the absorbent material This is because the moisture is sucked and discharged by the suction machine, the suction machine is set to the suction stop state, the absorbent material is restored to the original volume, and the water adhering to the surface of the umbrella fabric is absorbed. The dehydrating apparatus of the present invention does not remove the water adhering to the surface of the umbrella by directly sucking with an aspirator as in the prior art. The dehydrating apparatus of the present invention sucks the absorbent material with the suction device, sucks and discharges the moisture contained in the absorbent material with the suction device while reducing the volume of the absorbent material, stops the suction device, and restores the original by elasticity. The moisture on the surface of the umbrella is absorbed by the absorbent material that is restored to the above state. Accordingly, there is a feature that the moisture contained in the absorbent material can be sufficiently sucked and discharged as a simple structure without increasing the suction force of the suction machine, the running cost can be reduced, and the noise can be reduced.

  Further, the dehydrating device of the present invention is configured to suck and discharge the moisture contained in the absorbent material, without making the entire umbrella receiver into a sealed structure, and with a simple structure in the entire device, and also with an opening / closing mechanism. Thus, there is a feature that it is possible to suck moisture contained in the absorbent as a state of squeezing the absorbent, while having an extremely simple structure of sucking with an aspirator without sandwiching and crushing the absorbent. The dehydrating apparatus of the present invention is very simple without making the entire apparatus a sealed structure because the absorbent material is brought close to a sealed state in a state where the umbrella fabric inserted in the umbrella housing portion is in close contact with the inner surface of the absorbent material. Moisture contained in the absorbent material can be efficiently sucked with a simple structure. Moreover, since the fabric of the umbrella is brought into close contact with the entire inner surface of the absorbent material, there is a feature that moisture in a wider area can be absorbed while reducing the overlap of the fabric. Furthermore, since the dehydrating apparatus of the present invention reduces the volume of the absorbent without discharging the moisture by crushing the umbrella with the absorbent, the moisture contained in the absorbent in an extremely ideal state without damaging the umbrella. There is also a feature that can be discharged efficiently. As described above, the dehydrating apparatus that can efficiently drain the moisture of the absorbent material can realize the feature that the moisture adhering to the surface of the umbrella can be reliably removed in a short time.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below exemplifies an umbrella dewatering device for embodying the technical idea of the present invention, and the present invention does not specify the umbrella dewatering device as follows.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The umbrella dewatering device shown in FIGS. 1 and 2 includes an umbrella receiver 1 having an opening 10 for inserting an umbrella 30 wet in the rain, and the umbrella receiver 1 disposed on the inner surface of the umbrella receiver 1. An absorbent material 2 that absorbs and removes adhering water and a suction device 3 that sucks moisture absorbed by the absorbent material 2 are provided.

  The umbrella receiver 1 has an opening 10 into which the umbrella 30 is inserted. The umbrella receiver 1 shown in the figure has an inverted conical shape whose inner surface is tapered, and has a shape in which a closed umbrella 30 can be inserted. The umbrella receiver 1 having a tapered inner surface shape is provided with an umbrella housing portion 4 shaped along the surface of the umbrella 30 on the inner surface of the absorbent material 2 while making the thickness of the absorbent material 2 disposed on the inner surface uniform. Can be formed. However, although not shown, the umbrella receiver does not necessarily need to have a tapered inner surface shape, and the inner surface shape can be a curved surface, or the whole can be a cylindrical shape. This is because the thickness and shape of the absorbent material disposed on the inner surface of the umbrella receiver can be changed to make the shape of the inner surface of the umbrella housing portion formed on the inner side of the absorbent material a shape along the surface of the umbrella. Further, the umbrella receiver 1 of FIG. 1 is arranged in a posture with the opening 10 facing upward, that is, in a posture in which the axis is in the vertical direction. However, the umbrella receiver can also be arranged in a posture in which the axis is inclined with respect to the vertical direction.

  The umbrella receiver 1 is made of metal and is manufactured by processing a metal plate into a predetermined shape. However, the umbrella receiver 1 can be formed of a hard plastic. Further, in the dehydrating apparatus of FIG. 1, a casing 5 is disposed around the umbrella receiver 1, and the opening edge of the umbrella receiver 1 is exposed from the upper surface of the casing 5. Although not shown, the umbrella receptacle can be integrated with the casing.

  The umbrella receiver 1 has an absorbent material 2 disposed along the inner surface. The absorbent 2 absorbs water adhering to the surface of the wet umbrella 30 inserted from the opening 10. Further, the umbrella receiver 1 has a suction hole 6 communicating with the absorbent material 2 in order to suck the water absorbed by the absorbent material 2 with the suction device 3 and discharge it. The suction hole 6 is connected to the suction machine 3. The umbrella receiver 1 of FIG. 1 is connected to the suction machine 3 through a connection pipe 7 that is connected to the suction hole 6 by opening one suction hole 6 on the inner surface. Furthermore, the umbrella receiver 1 of FIG. 1 is provided with a suction hole 6 at the bottom of a tapered container. The suction hole 6 opened at this position has a feature that the water impregnated in the absorbent material 2 can be efficiently sucked. This is because the moisture absorbed by the absorbent 2 moves downward due to its own weight and is impregnated more in the lower part than in the upper part. However, the suction hole can also be provided in the middle part of the umbrella receptacle as shown by the chain line in the figure. The suction holes can efficiently suck moisture contained in the lower and upper portions of the absorbent material.

  As described above, the umbrella receiver 1 including the single suction hole 6 has a feature that the moisture contained in the absorbent material 2 can be sucked from the suction hole 6 with a strong suction force. However, the umbrella receiver can also open a plurality of suction holes. In the umbrella receiver having a plurality of suction holes, the connection pipes connected to the suction machine can be branched and connected to the suction holes, or the plurality of connection pipes can be independently connected to the suction machine. This umbrella receptacle can suck the moisture of the absorbent more efficiently by providing suction holes, for example, at the bottom and middle of the container. Further, the umbrella receiver has a feature that a plurality of suction holes are arranged at equal intervals so that moisture contained in the absorbent material can be sucked uniformly.

  Although the umbrella receiver 1 of FIG. 1 is composed of a single plate, the umbrella receiver may be a double structure. As shown in FIG. 3, the dual structure umbrella receiver 1 can be constituted by an inner container 11 and an outer container 12. In the umbrella receiver 1, a plurality of suction holes 6 are opened in an inner container 11, and a suction duct 13 is provided between the inner container 11 and the outer container 12. The suction duct 13 is connected to the suction machine 3 via the connection pipe 7. The umbrella receiver 1 having this structure causes the moisture contained in the absorbent material 2 to pass through the suction hole 6 of the inner container 11 through the suction duct 13 and sucked by the suction machine 3. As described above, the umbrella receiver 1 that sucks the suction duct 13 that is the gap formed between the inner container 11 and the outer container 12 by connecting the suction duct 13 to the plurality of suction holes 6 is provided with a plurality of suction holes 6. There is a feature that can be easily connected to 3.

  In the umbrella receiver 1 having a double structure, the inner container 11 can be any one of a punching plate, a perforated plate, and a wire mesh, and the outer container 12 can be a metal plate. The inner container 11 and the outer container 12 are processed into a predetermined tapered shape and are connected so as to have a predetermined interval. The distance between the suction ducts 13 formed between the inner container 11 and the outer container 12 is set to an optimum distance in consideration of the flow rate of air and moisture passing therethrough.

  The absorbent material 2 disposed on the inner surface of the umbrella receiver 1 is disposed in a state where the outer surface is in close contact with the inner surface of the umbrella receiver 1, and an umbrella housing portion 4 for inserting the umbrella 30 is provided on the inner side. Yes. The absorbent material 2 has a shape that follows the surface of the umbrella 30 that is inserted inside, with the inner surface of the umbrella housing 4 being tapered. The absorbent material 2 shown in FIG. 1 and FIG. 2 has a circular horizontal cross-sectional shape on the inner surface and an inverted conical shape on the inner surface of the absorbent material 2. FIG. 2 is a horizontal sectional view of the umbrella receiver 1 shown in FIG. However, this figure has shown the state which removed the umbrella. The absorbent material 2 having this shape is characterized in that the cloth 31 of the umbrella 30 can be smoothly adhered to the inner surface in a state of being sucked by the suction machine 3. In particular, the material 31 can be adsorbed while arranging a plurality of bones uniformly without difficulty. However, it is not always necessary for the absorbent material to have an inverted conical shape on the inner surface. For example, the absorbent material may have a polygonal shape, a star shape, a star shape (inner cycloid), a flower shape (outer cycloid), a circular shape having a corrugated outer periphery, or the like. The absorbent material having the inner surface shape in these shapes has a feature that the umbrella fabric can be uniformly adhered to the inner surface by evenly inserting the plurality of bones of the umbrella into the plurality of concave portions formed in the generatrix direction of the inner surface. In addition, there is a feature that the water on the surface can be efficiently absorbed by reducing the overlap of the fabric of the umbrella. Furthermore, the absorbent material can have an inner surface with a concave-convex shape to increase the surface area, and can be brought into contact with the surface of the umbrella fabric over a larger area.

  The absorbent material 2 has water absorption and cushioning properties. The absorbent material 2 is most preferably a soft synthetic resin foam having open cells. It is because it has excellent water absorption and cushioning properties. As this synthetic resin foam, for example, a flexible urethane foam can be used. However, as the absorbent material, soft foam rubber, sponge, cloth, paper, cotton, metal wool, water-absorbing wire mesh, or the like can be used. As the absorbent material, for example, the above members can be used alone, or a material obtained by mixing or laminating them can be used.

  The absorbent material 2 has a continuous porous void inside, and absorbs moisture adhering to the umbrella from the surface of the umbrella housing portion 4 with the void as a moisture absorption region. Moisture absorbed from the surface moves through continuous voids in the absorbent material 2 and is uniformly impregnated in the absorbent material 2. However, since a part of the water impregnated in the absorbent material 2 moves downward due to its own weight, the moisture content in the lower part of the absorbent material 2 may be higher than the upper part. Moisture absorbed by the absorbent 2 is sucked and discharged by the suction machine 3.

  The umbrella dehydrator of the present invention does not remove water adhering to the surface of the inserted umbrella by directly sucking it with a suction machine. The apparatus of the present invention sucks the absorbent material 2 by the suction machine 3, and at this time, the internal pressure of the absorbent material 2 is reduced to a negative pressure so that the volume of the absorbent material 2 is contracted to reduce the volume. Water is discharged from the absorbent material 2 as a state in which the absorbent material 2 is crushed, that is, as a state where the absorbent material 2 is squeezed. Furthermore, when the suction machine 3 is stopped in this state, the absorbent material that has been contracted and reduced in volume tends to be restored to its original state by elasticity. At this time, the porous voids that have been crushed by compression tend to expand to the original size, and air and moisture are sucked into the interior. That is, the moisture absorption region is regenerated inside the absorbent material, and moisture adhering to the surface of the umbrella 30 is absorbed from the surface of the absorbent material 2.

  The amount of water that can be impregnated in the absorbent material 2 varies depending on the amount of voids in the absorbent material 2. When the amount of voids in the absorbent material 2 increases, the amount of water that can be contained increases. Conversely, when the amount of voids in the absorbent material 2 decreases, the amount of water that can be contained decreases. The amount of voids in the absorbent material 2 is determined by the volume of the absorbent material 2 and the ratio (void ratio) of the porous voids inside. The volume of the absorbent material 2 is determined by the thickness of the absorbent material 2 and the length of the bus bar. The length of the busbar can be a radius of a general umbrella fabric, for example, 30 to 200 cm. The thickness of the absorbent material 2 can be set to, for example, 2 to 100 mm, preferably 3 to 50 mm, and more preferably 5 to 10 mm. Moreover, when the porosity of the absorbent material 2 is increased, the water absorption region formed inside increases and the effect of absorbing water increases. On the other hand, when the porosity is reduced, the water absorption region formed inside the absorbent material is reduced and the effect of absorbing water is reduced.

  Furthermore, the water absorption of the absorbent material 2 is also related to the size of the porous void formed inside. For example, when the absorbent material is made fine with a porous gap, it becomes easy to absorb moisture on the surface by capillary action. However, since the open cells formed inside become fine, the cushioning property is lowered. On the other hand, if the size of the porous voids in the absorbent material is increased, the action of the capillary phenomenon is reduced and the action of absorbing moisture on the surface is weakened, but the cushioning property of the absorbent material is improved and it becomes easy to deform. . For this reason, in the state sucked with the suction machine, the ratio of the volume being reduced is increased in the state where the inside is compressed with a negative pressure. In this way, the sufficiently reduced volume of the absorbent material can efficiently drain the contained moisture. Furthermore, the cushioning property of the absorbent material is also related to the porosity of the absorbent material. An absorbent material with a high porosity is easily deformed, and an absorbent material with a low porosity is difficult to deform. Therefore, the size and the void ratio of the absorbent material 2 are determined to be optimum values in consideration of the water absorption and cushioning properties of the absorbent material 2. In the absorbent material which is a synthetic resin foam, the resin material and the expansion ratio can be adjusted to obtain the optimum void ratio and void size.

  Furthermore, the absorbent material 2 shown in FIG. 1 is provided with a blocking film 8 on the upper surface. The closing film 8 closes the porous voids exposed on the surface of the absorbent material 2, and for example, an adhesive or paint can be used. The blocking film 8 is provided in a state in which an exposed portion of the upper surface of the absorbent material 2 is sealed by applying or spraying an adhesive or a paint on the upper surface of the absorbent material 2. The absorbent material 2 is sucked by the suction machine 3 and the exposed portion of the upper surface is blocked by the blocking film 8 in a state where the cloth 31 of the umbrella 30 inserted in the sucker housing portion 4 is in close contact with the inner surface. Therefore, it has the feature that it can compress and reduce the volume more efficiently. However, it is not always necessary for the absorbent material to block the upper surface with the blocking film. This is because the rate at which the volume of the absorbent material is reduced is reduced by inhaling air from this portion, but the moisture absorption area inside the absorbent material is increased by filling the inside of the absorbent material with the inhaled air. Because it will increase.

  The suction machine 3 sucks and discharges moisture impregnated in the absorbent material 2. The suction machine 3 is, for example, a vacuum pump. The suction machine 3 sucks air inside the umbrella receiver 1 from the suction hole 6. Since the absorbent material 3 is disposed in close contact with the inside of the umbrella receiver 1, the suction device 3 sucks the air inside the absorbent material 2 together with water.

  Further, in the suction state, the suction machine 3 sets the inside of the absorbent material 2 to a negative pressure and compresses the absorbent material 2 to reduce the volume. In the suction state of the suction machine 3, the volume inside the absorbent material 2 is reduced to a negative pressure because the cloth 31 of the umbrella 10 is adsorbed on the surface of the umbrella housing portion 4 of the suction material 2, and the absorbent material 2. This is because the surface of the film is blocked. Since the inside of the absorbent material 2 is connected in a state in which porous voids are continuous, the air is sucked from the surface of the absorbent material 2 by being sucked by the suction device 3. At this time, the cloth 31 of the umbrella 10 inserted into the umbrella housing portion 4 is adsorbed on the surface of the absorbent material 2 and closes the surface of the absorbent material 2. When the absorbing material 2 whose surface is closed is sucked by the suction device 3, the inside of the absorbing material 2 becomes negative pressure, and the volume of the porous space inside the absorbing material 2 is crushed and reduced. That is, the absorbent 2 is compressed and squeezed, and moisture impregnated inside is sucked by the suction device 3 and discharged. The water sucked by the suction device 3 is drained directly to the outside of the casing 5 or, although not shown, is temporarily stored in a tank disposed inside the casing and then drained.

  The suction machine 3 has a suction force capable of sucking moisture impregnated in the absorbent material 2. In particular, it has a suction force capable of compressing and reducing the volume of the absorbent material 2 whose surface is closed by the fabric 31 of the umbrella 30. However, the volume reduction rate of the absorbent material 2 is affected not only by the suction force of the suction machine 3 but also by the cushioning properties and the suction time of the absorbent material 2. For example, the suction device 3 sucks the absorbent 2 so that the pressure difference between the inside and the outside of the absorbent 2 is in the range of 1 Pa to 1100 hPa.

  The suction machine 3 is controlled to be turned on / off by an operation switch, or is controlled to be turned on / off by detecting that the umbrella has been inserted into the umbrella storage unit 4 with a sensor. The suction machine 3 can be driven, for example, only for a time when the operation switch is turned on, or for a time when the sensor detects the umbrella. Further, the suction machine 3 can be driven until a predetermined time elapses with a timer after the operation switch is turned on or the sensor detects the umbrella. The activation switch can be an automatic switch that is on when the umbrella is inserted and off when the umbrella is removed. The operation switch can also be manually controlled to be turned on / off.

  The dehydrating apparatus shown in FIG. 1 is provided with an operation switch 14 below the umbrella receiver 1. The dehydrating apparatus shown in this figure is arranged so that the umbrella receiver 1 can reciprocate up and down, and the umbrella 30 is inserted into the umbrella receiving portion 4 of the umbrella receiver 1 so that the umbrella receiver 1 is moved downward. In the depressed state, the operation switch 14 is pushed and turned on. The operation switch 14 is turned on when the umbrella receiver 1 is pushed down and turned off when the umbrella receiver 1 is pushed up. The dehydrating apparatus shown in the figure is provided with a convex portion 15 projecting downward on the lower surface of the umbrella receiver 1, and this convex portion 15 is inserted into and held by a guide tube 16 disposed below the umbrella receptacle 1. I am doing so. A spring 17 is disposed inside the guide tube 16, and the spring 17 is elastically deformed so that the umbrella receiver 1 can elastically reciprocate up and down. This dehydrating apparatus determines the time for operating the suction machine 3 by the time to push down the umbrella 30 inserted into the umbrella housing 4. That is, the suction machine 3 is operated for the time when the user depresses the umbrella receiver 1. Further, in this dehydrating apparatus, the umbrella receiver 1 is disposed in the upper opening of the casing 5 via a packing 18 that is elastically deformed in order to reciprocate the umbrella receiver 1 up and down.

  Further, in the dehydrating apparatus shown in FIG. 3, a recess 19 is provided in the center of the bottom surface of the inner container 11 of the umbrella receiver 1, and a sensor 20 is disposed in the recess 19. In the umbrella receiver 1, when the umbrella 30 is inserted into the umbrella accommodating portion 4 of the inner container 11 and the stone protrusion 32 is inserted into the concave portion 19 on the bottom surface, the sensor 20 detects this and the suction machine 3 is turned on. And Furthermore, the dehydrating apparatus shown in the figure is provided with a timer 21, and after the sensor 20 detects the umbrella 30, the suction machine 3 is turned on until a predetermined time elapses. When the sensor 20 detects that the umbrella 30 has been inserted into the umbrella housing 4, the dehydrator drives the suction device 3 until the timer 21 is activated and a predetermined time has elapsed. The time for which the timer 21 operates the suction device 3 is set to a time for the suction device 3 to suck the moisture contained in the absorbent material 2 to such an extent that the absorbent material 2 can absorb and remove the moisture adhering to the surface of the umbrella 30. Is done.

  FIG. 4 shows a state in which the dehydrating device having the above structure removes water adhering to the surface of the umbrella 30. However, this figure does not show in detail the porous void formed inside the absorbent material 2. In the actual absorbent material 2, a continuous porous void is formed inside, and moisture is absorbed in this void. Further, in this figure, water is schematically indicated by a circle in order to make the movement of the water easy to understand. However, in practice, water flows as a liquid without moving as water droplets.

(1) Insert the umbrella 30 into the umbrella housing 4 as shown in FIG. At this time, as shown in FIG. 4A, the fabric 31 of the umbrella 30 approaches or contacts the surface of the absorbent material 2, but water droplets adhering to the surface of the fabric 31 are almost not in the absorbent material 2. Not absorbed. This is because the absorbent material 2 contains an amount of moisture close to the limit that can be included. However, at this time, a part of the water droplets adhering to the surface of the fabric 31 of the umbrella 30 is absorbed by the absorbent material 2, and a part of the water drop is dropped and collected.
(2) When the umbrella 30 is inserted and the operation switch 14 is turned on, or when the sensor 20 senses that the umbrella has been inserted, the suction machine 3 is driven. The suction machine 3 sucks the absorbent 2 from the suction hole 6 on the inner surface of the umbrella receiver 1 through the connecting pipe 7. At this time, as shown in FIG. 4B, the moisture contained in the absorbent 2 is sucked from the suction hole 6. Further, air is sucked from the surface of the umbrella housing portion 4 which is the inner surface of the absorbent material 2, and the fabric 31 of the umbrella 30 is adsorbed to the absorbent material 2 by the negative pressure at this time.
(3) As shown in FIG. 4C, the suction machine 3 sucks moisture inside the absorbent material 2 in a state where the fabric 31 is in close contact with the surface of the absorbent material 2. Moisture inside the absorbent 2 sucked by the suction machine 3 moves through the continuous porous gap of the absorbent 2 and is discharged from the suction hole 6. Furthermore, since the inside of the absorbent material 2 sucked by the suction machine 3 has a negative pressure, the absorbent material 2 is pressed by the atmospheric pressure applied to the fabric 31 and the volume is reduced. Since the outer circumferential surface of the absorbent material 2 is in close contact with the inner surface of the umbrella receiver 1, as indicated by the white arrow A, the absorbent material 2 is compressed toward the outer circumferential direction and the volume is reduced.
(4) As shown in FIG. 4 (d), the absorbent material 2 is sucked with moisture by the suction device 3, and further contracts due to negative pressure to reduce its volume. When the absorbent 2 is compressed and its volume is reduced, the internal porous voids are crushed and the moisture contained therein is squeezed out. For this reason, the moisture impregnated in the absorbent 2 is more efficiently sucked into the suction machine 3 and discharged from the suction hole 6.
(5) When the time for which the suction machine 3 sucks the moisture of the absorbent material 2 elapses for a predetermined time, the suction machine 3 stops the suction.
(6) When the suction device 3 stops the suction, the absorbent material 2 that has been compressed and reduced in volume is elastically restored to its original volume as shown by the white arrow B in FIG. To do. In the absorbent material 2 restored to its original volume, the porous voids that have been crushed by the compression expand, and the moisture can be contained therein. In other words, the moisture absorption region capable of absorbing moisture is regenerated inside the absorbent material 2 and the moisture is absorbed from the surface. In this state, the absorbent 2 absorbs and removes moisture adhering to the surface of the umbrella 30 from the surface.
