Further, as a second problem, when the height of the drain tank 101 is increased and the tip 120a of the umbrella 120 is inserted into the drain tank 101, when the water level of the drain tank 101 increases, However, when the umbrella 120 is inserted, there is a problem that the tip 120a of the umbrella 120 is immersed in water and wets the tip 120a of the umbrella 120. Even when a storage portion is provided such that the water in the drainage tank 101 does not contact the tip portion 120a of the umbrella 120, drops attached to the umbrella 120 fall from the tip portion 120a of the umbrella 120 and accumulate in the storage portion. Will wet the tip 120a of the umbrella 120. As a countermeasure, there is a method of installing a drainage pump such as an electric type, but since the water in the drainage tank 101 is discarded by the user, the operability of cables and the like deteriorates and the cost of parts such as the pumps increases. There was also the problem of doing.
[0006]
Further, as a third problem, the capacity of the drainage tank 101 of the conventional umbrella dewatering machine 100 is about 2 liters, but even if the amount of water removed from one umbrella is 20 milliliters, About 100 bottles are full. This means that if one person uses the umbrella dewatering machine 100 per minute, the water will fill up in about 1.6 hours, and if the height of the drainage tank 101 is low, Since the capacity is reduced, the user must frequently discard the water in the drainage tank 101, which is complicated.
[0007]
Therefore, the present invention has been made in view of the problems of the above-described conventional umbrella water removal machine, and can correspond to almost all umbrellas while preventing an increase in the size of the device, and has good operability.

BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. First, the overall configuration of an umbrella water remover according to the present invention will be described with reference to FIGS.
[0017]
As shown in FIG. 1, the drainage tank 1 according to the present invention is disposed below the umbrella water remover 40, and the umbrella 20 is inserted from above the umbrella water remover 40. In the present embodiment, as in the conventional example, the position where the umbrella 20 is inserted is set to be about 80 cm above the ground, and the length of the umbrella 20 to be inserted is usually 65 cm. The size of the front and rear and left and right of the entire umbrella dewatering machine 40 is about 35 cm x 30 cm, the bottom area of the drainage tank 1 is about 30 cm x 25 cm, the effective height is about 15 cm, and the volume is 11 liters, Subtracting the volume of the umbrella tip accommodating section 2 described later results in an effective volume of about 10 liters.
[0018]
As shown in FIG. 2, the umbrella water remover 40 includes, from the top, a water removal unit 42, a control unit 44, and the drainage tank 1. The umbrella 20 includes a water removal unit 42, a control unit 44, And reaches the drain tank 1.
[0019]
The water removal unit 42 is connected to a suction motor 47 disposed in the control unit 44 by a suction pipe (not shown). The water collected by the water removal unit 42 is discharged from the drain port (not shown) into the drain tank 1 through a tank water supply port 13 (see FIG. 5) provided on the upper surface of the drain tank 1.
[0020]
The operation switch 43 disposed on the control unit 44 is rotatably held by the control unit 44, detects passage of the distal end portion 20 a of the umbrella 20 that has passed through the water removal unit 42, and controls the suction motor 47 via the control board 45. Is performed. Further, a full-water sensor 46 is disposed on the lower surface of the control unit 44 at a position facing a full-water float 14 described later. An operation lamp 41 is disposed above the umbrella water remover 40.
[0021]
Next, the configuration of the drainage tank 1 according to the present invention will be described in detail with reference to FIGS.
[0022]
As described above, the tip 20a of the umbrella 20 is inserted into the umbrella water remover 40 so as to penetrate the center of the umbrella water remover 40 (see FIGS. 1 and 2), and reaches the drain tank 1. . Therefore, the umbrella tip accommodation section 2 is disposed in the center of the drainage tank 1.
[0023]
The umbrella tip accommodation section 2 is configured in such a manner that an outer container 3 and an inner container 4 are stacked. The outer container 3 is formed integrally with the upper surface of the drainage tank 1, and is formed in a cup shape having a predetermined angle (3 ° in this embodiment) on the inner surface. In the upper part of the outer container 3, drain holes 12 are arranged on all sides.
[0024]
The inner container 4 is provided with an inclined portion on the outer peripheral surface at substantially the same angle as the inner peripheral surface of the outer container 3 (3 ° in this embodiment). Thereby, when the inner container 4 is overlaid on the outer container 3, the inner container 4 is substantially closely attached to the outer container 3. In the case of the present embodiment, a configuration is provided in the upper end portion of the inner container 4 in which a flange portion 4a is provided in the circumferential direction to prevent over-pressing, and a slight gap is left between the outer container 3 and the inner container 4. And In addition, a water absorption hole 11 is formed in a lower portion of the inner container 4 and can be opened and closed by the operation of the water absorption valve 6.
[0025]
A damper 7 is provided on the upper surface of the water absorption valve 6 to protect the water absorption valve 6 from an impact caused by the contact of the tip 20a of the umbrella 20. The water absorption valve 6 is provided by a water absorption valve spring 9 and the inner container in a normal state. 4 is lifted so as to form a gap between the bottom surface 4.
[0026]
The inner container 4 is lifted upward by a spring 8 and held so as to be movable up and down, and the upper limit position is regulated by the insertion guide 5.
[0027]
The insertion guide 5 functions as a guide when the umbrella 20 is inserted, and is fixed to the drainage tank 1.
[0028]
Here, when the inner container 4 is pushed down, the inner periphery of the outer container 3 and the outer periphery of the inner container 4 are substantially close to each other, and when the inner container 4 is lifted by the spring 8, as shown in FIG. , A gap a exists. The spring constant of the spring 8 and the water absorption valve spring 9 is set to be sufficiently larger in the spring 8 than in the water absorption valve spring 9. The umbrella 20 is finally pushed down to the position shown in FIG.
[0029]
The full-water float 14 is disposed on the upper surface of the drainage tank 1, floats upward as the collected water level rises, and gradually approaches the full-water sensor 46 disposed in the control unit 44.
[0030]
Next, the operation of the drainage tank having the above configuration will be described in detail.
[0031]
The water falling into the drainage tank 1 is roughly classified into water collected by the operation of the water removing unit 42 shown in FIG. 2 and water dropped from the umbrella 20 itself.
[0032]
Here, the water collected by the water removal unit 42 accumulates outside the umbrella tip housing section 2 and does not enter the umbrella tip housing section 2. In the umbrella tip receiving section 2, water drops that drop when the umbrella 20 is inserted into the umbrella water remover 40, and water that falls from the umbrella 20 due to vibrations when water is removed by the water removal unit 42 are directly collected. Is done.
[0033]
FIG. 7A shows a state in which drops from the tip portion 20 a of the umbrella 20 have accumulated in the umbrella tip storage section 2. In this example, about 140 g of water is stored in the umbrella tip storage section 2 in the range indicated by the hatched portion. Here, on a rainy day, the amount of water adhering to the umbrella 20 having a length of 65 cm is about 40 to 50 g, and about 10 g of water directly falls from the tip 20a of the umbrella 20 to the umbrella tip accommodation unit 2. FIG. 7A shows a state that occurs when the pump mechanism is not operated or when a short-length umbrella is continuously used. The position of the water collected by the water removal unit 42 is up to the outer water surface position.
[0034]
FIG. 7B shows a state where the umbrella 20 of about 65 cm has been inserted thereafter. When the umbrella 20 of about 65 cm is inserted, first, the tip portion 20a of the umbrella 20 pushes down the damper 7 and the water absorption valve 6. As described above, the water absorption valve spring 9 is sufficiently weak with respect to the spring 8, so that the space between the inner container 4 and the water absorption valve 6 is first closed. As a result, the water accumulated in the inner container 4 loses the outlet, and the water accumulated in the outer container 3 is prevented from moving to the inner container 4.
[0035]
After this, the umbrella 20 continues to descend, but as a result, the water accumulated between the inner container 4 and the outer container 3 has lost its place to go and was present between the outer container 3 and the inner container 4. It rises along the gap a. The gap a gradually decreases with the lowering of the inner container 4, but the gap exists even when it is lowered to the lowermost end, so that the pushed-up water is vigorously discharged upward. Here, the flange 4a provided at the upper end of the inner container 4 functions to change the traveling direction of the water discharged upward to the outer peripheral direction. The water whose traveling direction has been changed to the outside collides with the inside of the insertion guide 5, and is discharged through the discharge hole 12 to the outside of the umbrella tip receiving section 2. According to experimental values, about 50 g of water is discharged by this one operation, and 90 g of water remains in the drain tank 1.
[0036]
Thereafter, at the same time as the umbrella 20 is raised, the inner container 4 is also started to rise by the spring 8, and the inner container 4 is stopped by the insertion guide 5. Next, the water absorption valve 6 and the damper 7 are raised by the water absorption valve spring 9. As a result, the water absorption hole 11 that has been closed is opened, and the water trapped in the inner container 4 falls to the outer container 3. As a result, the water accumulated in the inner container 4 is discharged, and the state shown in FIG. 7C is reached, and the water does not contact the tip 20a of the umbrella 20.
[0037]
Further, by repeatedly inserting and removing the umbrella 20, the amount of water remaining in the drainage tank 1 is reduced to 60 g and 45 g, and drainage is performed until the water level pushed up by the movement of the inner container 4 does not reach the drain hole 12 of the outer container 3. Repeated. In this way, even if a larger amount of water is accumulated in the inner container 4, it can be drained by performing the above operation several times.
[0038]
【The invention's effect】
As described above, according to the present invention, it is possible to cope with almost all umbrellas while preventing the device from being enlarged, and it is easy to operate, and it is possible to reliably prevent the tip of the umbrella from getting wet. Thus, it is possible to provide a drainage tank and an umbrella water remover capable of reducing the number of times of drainage work.
