  According to the invention described in the preceding item (1), the heel portion, which is a cloth portion of the wet umbrella, comes into contact with the water absorbing sheet disposed so as to surround the umbrella housing portion and absorbs water. At the same time, since the water absorption chamber having an annular cross section formed outside the water absorbent sheet is sucked by the suction device, the water absorbed by the water absorbent sheet is sucked out and discharged from the water absorbent sheet by the suction force.

  The water absorption chamber is partitioned in the length direction of the umbrella housing space to form a plurality of unit chambers, and the suction device is one of the plurality of unit chambers of the partitioned water absorption chamber. The unit chamber is connected to and sucked in the unit chamber. By this suction operation, the unit chamber is sucked and the water absorbing sheet of the portion existing inside the unit chamber is sucked, and as a result, the buttocks of the umbrella inside the sucking portion of the water absorbing sheet are sucked and spread, and the water absorbing sheet The water that adheres and adheres to the buttock is further absorbed by the water absorbing sheet. By the water absorption operation by the water absorption sheet and the water absorption operation by the suction force acting on the water absorption sheet in the unit chamber, the water adhering to the heel portion of the umbrella is surely dehydrated in the portion corresponding to the unit chamber.

  On the other hand, when the negative pressure of the unit chamber increases and reaches a constant level due to the suction force acting on one unit chamber, the damper member that is normally biased in the direction of closing the communication hole is displaced, and the partition portion Open the communication hole. As a result, the unit chambers on both sides of the partition portion communicate with each other, and the suction force by the suction device that has been acting only on one unit chamber also acts on the other unit chamber. As a result, the water-absorbing sheet of the portion existing inside the other unit chamber is sucked, and as a result, the buttocks of the umbrella inside the sucking portion of the water-absorbing sheet are sucked, adhere to the water-absorbing sheet, and adhere to the buttocks The absorbed moisture is absorbed by the water absorbing sheet. In this way, moisture adhering to the buttocks of the umbrella is reliably dehydrated in the portion corresponding to the other unit chamber.

  When the negative pressure of the other unit chamber increases and exceeds a certain value, the next-stage damper member is actuated and a suction force acts on the next-stage unit chamber, and in the portion corresponding to the next-stage unit chamber, Moisture adhering to the buttocks of the umbrella is surely dehydrated.

  In this way, the suction force by the suction device acts in a stepwise manner for each unit chamber constituting the water absorption chamber, and the buttocks of the umbrella are sucked and expanded each time, and are in close contact with the water absorption sheet in order, and the umbrella is in the length direction. It is dehydrated step by step. In other words, rather than letting the suction force act on the water absorption chamber at the same time, it acts on the water absorption operation step by step while acting locally on each narrow unit chamber to ensure dehydration of that part of the umbrella. The entire umbrella can be dehydrated very efficiently.

  According to the invention described in (2) above, a support having an annular cross section having a large number of through holes is provided between the umbrella housing portion and the water absorption chamber, and the water absorption sheet is disposed on the inner surface of the support. Therefore, it is possible to reliably make contact between the buttocks of the umbrella and the water absorbing sheet.

  According to the invention described in item (3) above, since the support body has radial inward convex portions and concave portions formed between adjacent inward convex portions in the cross section, the closed umbrella The outer peripheral shape can be made to conform to the inner surface of the support, and dewatering can be performed more efficiently.

  According to the invention described in item (4) above, since the water absorbent sheet has a large number of through holes penetrating the sheet in the thickness direction, air flows through the through holes during suction by the suction device. This facilitates the removal of moisture from the peripheral portion of the through hole, and instead of the separated water, the water in the water absorbent sheet moves to the peripheral portion of the through hole by capillary action, and the air flowing through the through hole We will leave sequentially. By repeating this, the water removal efficiency from the water absorbent sheet is improved, the water absorption efficiency of the water adhering to the buttocks of the umbrella by the water absorbent sheet is improved, and further excellent dewatering efficiency can be realized.

  According to the invention described in item (5), the opening of the umbrella housing portion is provided with a cylindrical guide member for inserting and extracting the umbrella, and the inner surface of the guide member is arranged in the length direction. Is formed in a tapered surface that gradually increases in diameter toward both ends in the length direction with the intermediate position as a small diameter portion, so when inserting the umbrella into the insertion opening of the accommodation space, The master bone of the umbrella can be guided and smoothly inserted into the tapered surface of the outer portion. On the other hand, when extracting after dehydration, the main bone of the umbrella can be guided and smoothly extracted on the tapered surface of the inner portion in the length direction of the guide member.

  According to the invention described in item (6) above, the inner surface of the guide member is formed in a star shape having a cross section in which the outer concave portions and the inner convex portions are alternately arranged in the circumferential direction. The umbrella can be guided in a manner fitted in the outward recess of the guide member, and the position of the umbrella in the umbrella housing portion can be restricted to an appropriate position.

  According to the invention described in the preceding item (7), in the vicinity of the umbrella housing portion, the star-shaped guide member having a transverse cross section has the umbrella extending from the outer concave portion of the inner surface to the guide groove of the inner convex portion of the support. Since the derivative that guides the master bone is provided, the master bone of the umbrella can be reliably guided to the guide groove of the inward convex portion of the support, and the buttock between the adjacent master bones of the umbrella in the outer concave portion of the support Can be disposed, and more efficient dehydration can be performed.

Such inconveniences can be prevented.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view showing a schematic configuration of an umbrella dewatering apparatus according to an embodiment of the present invention.

  This umbrella dewatering device includes a dewatering tank 20, a suction device 30, a guide member 40, a drainage device 50 and the like housed in a box-shaped device case 10.

  As shown in FIGS. 2 and 3, the dewatering tank 20 includes a first hollow body 21 having an inverted octagonal pyramid shape whose upper surface is open and whose cross-sectional area is reduced downward, and a lower end portion of the first hollow body 21. And the bottomed second hollow body 22 connected to the bottom.

  Inside the dehydration tank 20, a support body 60 having a large number of oblong through holes 61 is provided along the inner surface of the dehydration tank 20. The support 60 is for supporting the water absorbing sheet 70 on the inner surface thereof, and the cross-sectional area decreases in the length region of the first hollow body 21 of the dewatering tank 20 from the upper end to the lower end. The inverted octagonal pyramid shape is formed, and the length region of the second hollow body 22 is formed in an inverted conical shape. And in the length area | region of the 1st hollow body 21 of the spin-drying | dehydration tank 20, in the cross section, the radial inward convex part 62 and the outward recessed part of the cross-sectional pentagon shape formed between the adjacent inward convex parts 62 63.

  The support body 60 is disposed at a certain distance from the inner surface of the dewatering tank 20, so that the support body 60 crosses between the inner surface of the dewatering tank 20 and the support body 60 in the length direction of the dewatering tank 20. A surface-annular water absorption chamber 80 is formed. Further, the internal space of the support body 60 is an umbrella housing portion 90 having an opening 91 at the top.

  The water absorbent sheet 70 is supported in close contact with the inner surface of the support body 60 in a manner that surrounds the umbrella housing portion 90. The water absorbing sheet 70 is for contact water absorption of rainwater adhering to the collar portion 102 (shown in FIG. 7) of the umbrella 100, and has a known configuration made of a material such as resin. In addition, although the water absorption sheet 70 may be partially joined to the inner surface of the support body 60, it is desirable to attach in the aspect which can be replaced.

  In the dehydration tank 20, a partition portion 23 is provided at a boundary portion between the first hollow body 21 and the second hollow body 22, and a plurality of partition portions 24 are also provided in the first hollow body 21. . By these partition parts 23 and 24, the water absorption chamber 80 between the dehydration tank 20 and the support body 60 is partitioned into a plurality of lengths of the umbrella housing part 90 or the dehydration tank 20, as shown in FIG. As shown, it is divided into a plurality of unit chambers 81. In this embodiment, a total of seven unit chambers 81 are formed.

  The unit chamber 81 located at the bottom, that is, the unit chamber 81 inside the second hollow body 22 is connected to the intake pipe 31 at the bottom of the second hollow body 22, and the other end of the intake pipe 31 is The unit chamber 81 inside the second hollow body 22 is sucked through the suction pipe 31 by the suction operation of the suction device 30 connected to the suction device 30. Reference numeral 25 shown in FIGS. 2 and 5 is an umbrella tip fitting portion that protrudes from the bottom of the second hollow body 22, and one end of a drain pipe 39 is connected to the umbrella tip fitting portion 25. The other end of the chair pan and pan 9 is connected to a moisture releaser 52 which will be described later, and the water accumulated in the umbrella tip fitting portion 25 is drained to the moisture releaser 52 through the drainage pipe 9. .

  In addition, each of the partition portions 23 and 24 is formed with a communication hole 26 that connects the unit chambers 81 adjacent to each other vertically through the partition portions 23 and 24, and a damper member 27 that opens and closes the communication hole 26. Is provided.

  That is, as shown in detail in FIG. 4, one end of the damper member 27 is pivotally attached by a hinge 28a on the back surfaces (lower surfaces) of the partition portions 23 and 24, and the other end of the damper member 27 is in the vertical direction. Is attached to the upper end of the compression spring 28b. Further, an L-shaped angle 28c is attached to the back surface of the partition portions 23, 24, and an upward projecting bolt 29a is fixed to the horizontal portion 28d of the L-shaped angle 28c. The bolt 29a is attached with a nut member 29b for adjusting the spring force that moves in the length direction of the bolt 29a by a rotation operation, and the compression spring 28b is inserted into the bolt 29a and the lower end of the spring is at the lower end. It is supported by the nut member 29b.

  Therefore, by rotating the nut member 29b for adjusting the spring force, the nut member 29b moves up and down along the length direction of the bolt 29a.

  The damper member 27 is urged upward by the compression spring 28b, and the communication hole 26 is normally closed.

  On the other hand, when the lower unit chamber 81 is sucked by the operation of the suction device 30, a portion of the water absorbent sheet 70 existing inside the sucked unit chamber 81 passes through the through hole 61 of the support 60. As a result, the collar portion 102 of the umbrella 100 existing inside the water absorbing sheet 70 is sucked and is in close contact with the water absorbing sheet 70, and the unit chamber 81 has a negative pressure. When the negative pressure reaches a certain value, the damper member 27 is pulled downward against the spring force as shown by a chain line in FIG. 4, and the communication hole 26 is opened and sucked into the unit chamber 81 adjacent to the upper side. A suction force by the device 30 is applied.

  The magnitude of the compression force of the spring 28b determines the timing at which the suction force starts to act on the upper unit chamber 81, and the position of the nut member 29b is adjusted so that the communication hole 26 opens at an appropriate timing. By doing so, the biasing force by the spring 28b is adjusted in advance.

  Further, the upper wall of the uppermost unit chamber 81 closest to the opening 91 of the umbrella housing 90 is formed with a communication hole 48 that communicates the unit chamber with the atmosphere. In this embodiment, as will be described later, the upper wall of the uppermost unit chamber 81 is constituted by the lower end flange 41 of the guide member 40, so that the continuous pain hole 48 is formed at the lower end flange 41 of the guide member 40. Has been drilled.

  Further, the back surface (lower surface) of the lower end flange portion 41 is normally urged by a spring in a direction to close the communication hole 48, and the uppermost unit chamber 81 is formed by the suction operation of the suction device 30. A damper member 271 that opens the communication hole 48 and opens the unit chamber 81 to the atmosphere when a certain negative pressure is reached is provided. The mounting structure of the damper member 271 is the same as the mounting structure of the damper member 27 shown in FIG.

  The damper member 271 operates as a safety device. That is, in this embodiment, as will be described later, the suction device 30 is operated by the user operating the foot switch. For example, after the user operates the foot switch, the umbrella 100 is inserted into the umbrella housing portion 90. Then, an abrupt suction force acts on the umbrella 100 and is abruptly pulled, which may damage the umbrella.

  Therefore, when an unintentionally large suction force acts on the umbrella, when the suction force reaches the uppermost unit chamber 81 and reaches a certain negative pressure, the damper member 271 is activated and the communication hole 48 is opened. The unit chamber 81 and thus the entire water absorption chamber 80 are opened to the atmosphere. For this reason, it is suppressed that the excessive attraction | suction force beyond it acts on an umbrella, and inconveniences, such as damage of an umbrella, can be prevented.

  A cylindrical guide member 40 for inserting and removing the umbrella is continuously provided at the upper end of the umbrella housing 90. As shown in FIG. 7, the guide member 40 is formed so that the outer peripheral shape of the lower end flange is substantially the same as the outer peripheral shape of the upper end opening 20 a of the dewatering tank 20. It is joined to the part 20a. Thereby, the cylindrical hollow part 42 of the guide member 40 and the umbrella accommodating part 90 in the dehydrating tank 20 communicate with each other, and the user of the dehydrating apparatus can pass through the cylindrical hollow part 42 of the guide member from the outside of the guide member 40. An umbrella can be inserted into the umbrella housing portion 90.

  As shown in FIGS. 7 and 8, the inner surface of the guide member 40 is formed in a star shape with a cross section in which eight outer concave portions 43 and inner convex portions 44 are alternately arranged in the circumferential direction. . In addition, the inner surface of the guide member 40 is formed with tapered surfaces 45 and 46 that gradually increase in diameter toward both ends in the length direction, with an intermediate position in the length direction as a small diameter portion. In FIG. 8, the damper member 271 attached to the lower end flange 41 of the guide member 40 is omitted.

  By using such tapered surfaces 45 and 46, even when the umbrella is slightly opened when the umbrella is inserted, it is smoothly guided by the upper tapered surface 45 and enters the umbrella housing portion 90. On the other hand, when the umbrella is taken out, the umbrella is guided by the lower tapered surface 46, and the umbrella can be smoothly taken out without being caught by the tip of the parent bone of the umbrella.

  In addition, as shown in FIG. 7, on the upper surface of the guide member 40, the umbrella is inserted into the outer position of the one outer concave portion 43 so that the one main bone 101 of the umbrella 100 matches the outer concave portion 43. A mark 47 is attached for receiving. In this way, when one umbrella bone 101 of the umbrella 100 is matched with the outer concave portion 43 and the umbrella is inserted, the other parent bones of the umbrella also match with the other outer concave portion 43, respectively. There is a high possibility that the umbrella will be inserted in a proper positional relationship.

  As shown in FIG. 1, the dehydration tank 20 and the guide member 40 are in a state in which the upper end of the guide member 40 faces the opening 12 of the inclined upper surface plate 11 of the apparatus case 10 and the axes thereof are inclined. It is arranged in the device case 10. By arranging the dewatering tank 20 and the guide member 40 in the inclined state in this way, it becomes easy to perform the operation of putting the umbrella in and out of the dewatering tank 20, and the usability is improved.

  As shown in FIG. 1, the suction device 30 is of a type in which a blower is operated by a motor 38, and the sucked air in the water absorption chamber 80 is sent to the exhaust port 33 through the exhaust pipe 32, On the other hand, the water that has been sucked together with the air is stored in the water storage section 34 while being discharged out of the apparatus.

  As shown in detail in FIG. 6, the water storage section 34 has a water drop opening 35 at the bottom thereof, and is displaced in the direction of closing the drop opening 35 by a suction force during the suction operation near the drop opening 35. When the suction operation is released, a lid body 36 that is displaced downward by its own weight and opens the drop port 35 is pivotally mounted. In addition, the code | symbol 37 shown in FIG. 6 is a stopper which controls the maximum rotation position by the dead weight of the cover body 36. FIG.

  The motor 38 starts rotating when a user operates a foot switch (not shown), and stops when a predetermined time set by a timer elapses.

  The motor 38 may be stopped by a user's switch operation, or the operation of the motor 38 is automatically started by providing a sensor for detecting that the umbrella is accommodated in the umbrella accommodating portion 90. It is good also as a structure.

  The drainage device 50 is installed below the moisture dropping port 35. The drainage device 50 includes a drainage tank 51 and a moisture discharger 52 connected to the drainage tank 51. The drain tank 51 receives and accumulates water dropped from the drop port 35 of the water storage section 34.

  The moisture discharger 52 includes a supersonic oscillator (ultrasonic vibrator) 53. After the water is atomized by ultrasonic waves, the moisture is discharged from the exhaust port 33 through the exhaust pipe 54 to the outside of the apparatus. Has been made.

  In this embodiment, a large number of circular through holes 71 are formed in the water absorbent sheet 70 over almost the entire surface. Such a through hole 71 is formed for the following reason.

  That is, when the suction device 30 performs suction, air flows through the through hole 71 in a portion overlapping the through hole 61 of the support 60. As a result, the detachment of moisture from the peripheral edge of the through hole 71 is promoted, and the water in the water absorbent sheet 70 moves to the peripheral edge of the through hole 71 by capillary action instead of the detached water. It is further separated by the circulating air. This is because by repeating this, the efficiency of sucking out moisture from the water absorbent sheet 70 is improved, and as a result, the efficiency of absorbing water attached to the umbrella by the water absorbent sheet 70 is improved. Such an effect is exhibited as an independent effect even if the water absorption chamber 80 is not divided into a plurality of unit chambers 81 by the partition portions 23 and 24. The number of the through holes 71 is set so that the number or the opening ratio of the through holes 71 in the unit chamber is substantially constant in each unit chamber in order to make the water absorption efficiency of the entire water absorbing sheet 70 uniform. Is good.

  Next, the operation of the umbrella dewatering device shown in FIGS. 1 to 8 will be described.

  The user inserts the wet umbrella 100 into the cylindrical hollow portion 42 of the guide member 40 from the tip thereof. At this time, an arbitrary one of the main bones 101 of the umbrella 100 is inserted in accordance with the position of the mark 47 on the upper surface of the guide member 40. Then, each master bone 101 fits into each outer recess 43 on the inner surface of the guide member 40 and enters. Further, since the inner surface of the guide member 40 is formed in a tapered surface 45 that is tapered toward the entry direction of the umbrella 100, the umbrella 100 is smoothly guided by the tapered surface 45 and is placed in the umbrella housing portion 90. It goes in.

  In a state where the umbrella 100 is housed in the umbrella housing portion 90, each of the main bones 101 of the umbrella 100 is located in each of the outward recesses 63 of the support body 60. At this time, a part of the collar part 102 of the umbrella 100 is brought into contact with the water absorbing sheet and absorbed.

  In this state, when the user operates the foot switch and drives the motor 38 of the suction device 30, the blower is activated, and the lowermost unit chamber 81 of the water suction chamber 80 is sucked through the intake pipe 31. By this suction operation, the water absorbing sheet 70 existing inside the lowermost unit chamber 81 is sucked through the through hole 61 of the support 60 and further exists inside the suction portion of the water absorbing sheet 70. The collar part 102 of the umbrella 100 is sucked and spreads, closely contacts the water absorbing sheet 70, and moisture adhering to the collar part 102 is further absorbed by the water absorbing sheet 70. By the water absorption operation by the water absorption sheet 70 and the water absorption operation by the suction force acting on the water absorption sheet 70 in the unit chamber 81, the water adhering to the collar portion 102 of the umbrella 100 is surely dehydrated inside the unit chamber 81. In addition, since a large number of through holes 71 are formed in the water absorbent sheet 70, the air flows through the through holes 71 by the suction force. As a result, the water is released from the peripheral edge of the through holes 71 and the water in the water absorbent sheet. To the through hole 71 is promoted, and the dehydration efficiency is further increased.

  On the other hand, when the negative pressure of the unit chamber 81 increases and reaches a certain value due to the suction force acting on the lowermost unit chamber 81, the spring 28b is normally biased in a direction to close the communication hole 26 of the partition portion 23. The damper member 27 is displaced, and the communication hole 26 of the partition part 23 is opened. As a result, the unit chamber 81 located at the next (upper) stage communicates with the lowermost unit chamber 81, and the suction force by the suction device 30 acting only on the lowermost unit chamber 81 is reduced to the next unit chamber. 81 also works. As a result, the water absorbent sheet 70 existing inside the unit chamber 81 at the next stage is sucked, and as a result, the collar portion 102 of the umbrella 100 present inside the water absorbent sheet 70 is sucked and adhered to the water absorbent sheet 70. Then, the water adhering to the flange 102 is further absorbed by the water absorbing sheet 70. In this way, the water adhering to the collar portion 102 of the umbrella 100 is reliably dehydrated in the portion corresponding to the next unit chamber 81.

  When the negative pressure in the next-stage unit chamber 81 increases and exceeds a certain value, the damper member 27 is displaced so as to open the communication hole 26, and a suction force acts on the next-stage unit chamber 81. In the portion corresponding to the chamber 81, the water adhering to the collar portion 102 of the umbrella 100 is surely dehydrated.

  Thus, the suction force by the suction device 30 acts in a stepwise manner from the lowermost unit chamber 81 to the uppermost unit chamber for each unit chamber 81 constituting the water absorbing chamber 80, and accordingly, the umbrella 100 As a result of the portion 102 being sequentially sucked and expanded from the lower side and in close contact with the water-absorbing sheet, the umbrella 100 is dehydrated sequentially from the front end side in the length direction. In other words, the suction force is not applied to the water absorption chamber 80 at the same time, but the water absorption operation is applied stepwise while the umbrella 100 in that portion is surely dehydrated for each narrow unit chamber 81. Therefore, compared to the case where the entire umbrella 100 is simultaneously water-absorbed and sucked, air leakage due to poor adhesion between the collar portion 102 of the umbrella 100 and the water-absorbing sheet 70 can be suppressed, and suction is performed almost over the entire collar portion 102. The force can be reliably applied, and the umbrella 100 can be dehydrated extremely efficiently.

  When a certain time has elapsed after the start of suction, the timer is activated to stop the motor 38 and release the suction force. Then, the damper member 27 of each unit chamber 81 is displaced in the direction of closing the communication hole 26 by the urging force of the spring 28b, and becomes a normal state.

  After the motor 38 is stopped, the user may pull out the umbrella 100 from the umbrella housing portion 90 via the guide member 40. At this time, since the lower half of the inner surface of the guide member 40 is formed with a tapered surface 46 that is narrowed in the direction of taking out the umbrella, the tip of the main bone 101 of the umbrella 100 is guided to the tapered surface 46 while the umbrella 100 is It is pulled out smoothly.

  On the other hand, the water sucked by the suction device 30 is stored in the water storage section 34 during the operation of the suction device 30, and when the operation of the suction device 30 stops, the lid body 36 opens and falls to the drain tank 51. The water stored in the drain tank 51 and the water in the umbrella tip fitting portion 25 sent by the drain pipe 39 are atomized by the ultrasonic oscillator 53 of the moisture releaser 52 and exhausted through the exhaust pipe 54. It is discharged out of the apparatus through the port 33.

It is desirable to adhere.

  Therefore, in this embodiment, when the umbrella 100 is inserted, the main bone 101 is to be guided to the tip of each inward convex portion 62 of the support body 60.

  That is, a guide groove having a V-shaped or U-shaped cross section that guides the main bone 101 of the umbrella 100 along the length direction of the inward convex portion 62 at the front end portion in the protruding direction of the inward convex portion 62 of the support 60. 64 is formed. On the other hand, a V-shaped or U-shaped derivative 110 extending from the outer concave portion 43 of the guide member 40 to the inner convex portion 62 of the support body 60 is attached to the lower tapered surface 46 of the guide member 40 by welding or the like. It has been.

  With such a configuration, when the umbrella 100 is inserted, the main bone 101 fitted in each outer recess 43 on the inner surface of the guide member 40 moves downward along the outer recess 43 as the umbrella 100 enters. The umbrella 100 is accommodated in the umbrella accommodating portion 90 while being guided by the derivative 110 and moved along the guide groove 64 of the support 60, and the parent bone 101 is fitted in the guide groove 64. The flange portion 102 is disposed in the outer concave portion 63 of the support body 60.

  For this reason, at the time of dehydration, the collar portion 102 of the umbrella 100 can be brought into close contact with the inner surface of the outer concave portion 63 having a pentagonal cross section so that more efficient dehydration can be performed.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, although the suction device 30 is connected to the lowermost unit chamber 81, the uppermost unit chamber 81 or an intermediate unit chamber 81 may be used.

  In addition, the guide member 70 has a cylindrical hollow portion 42 having a star-shaped cross section. However, as shown in FIG. 11, a guide member 40 having a cylindrical hollow portion 42 having a circular cross section may be used. In FIG. 11, the communication hole 48 and the damper member 271 are omitted.
