Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella dehydrating / drying machine which is used by an unspecified number of people at the entrance of a building in rainy weather and which dehydrates and dries a wet umbrella in a short time.

[0002]

2. Description of the Related Art There are two forms of dewatering of a wet umbrella: a method of fully opening the wet umbrella for dehydration and a method of narrowing and dewatering the wet umbrella.

[0003] As means for dehydrating a wet umbrella, "suction by a water absorbing body", "suction by vacuum", "blowing by air jet"
Examples include “evaporation by heating”, “separation by centrifugal force”, “shaking off by mechanical vibration”, “squeezing by a flexible body”, and “combination of a plurality of means”.

[0004] The method of fully opening the umbrella is not widely used because the size of the apparatus is increased and the installation area is reduced several times as compared with the method of performing the operation. On the other hand, there was a product of a method in which the umbrella was closed and the water in the umbrella cloth was absorbed by a water absorber, and the water in the water absorber was sucked by a blower.

[0007] For the reasons described, the dewatering effect is low and it has hardly spread.

[0005]

It is not welcome to carry a wet umbrella or carry it indoors. Despite the demand for umbrella dewatering equipment, it has not become widespread. The reason seems to be that the performance of the conventional umbrella dewatering machine was low. An object of the present invention is to provide an "umbrella dehydration dryer" having a small size and a high dehydration effect in a short time.

[0006]

In the case of an umbrella having high water repellency, water adhering to the umbrella is scattered as water droplets on the surface of the umbrella cloth, the amount of adhesion is small, and the umbrella is easily separated by mechanical vibration. On the other hand, an umbrella with low water repellency adheres to the entire surface of the umbrella cloth as a water film and soaks into the umbrella cloth, so that the umbrella has a large amount of adhesion and is difficult to be detached by mechanical vibration.

FIG. 4 is a cross-sectional view when a wet umbrella having low water repellency is narrowed, and is an example of the shape of an umbrella cloth A4. The shape is not uniform because it is deformed by the situation when the wet umbrella is narrowed and the subsequent external force. However, it is common that umbrella cloths A4 adhere to each other due to the surface tension of water B. In any case, most of the attached water B is sandwiched between the umbrella cloth A4 and the umbrella cloth A4. In this state

[0003] Even with the dewatering means described, the umbrella cloth A4 prevented the water B from separating, and the dewatering effect in a short time was low.

[0008] In the case of a dry umbrella, the shape is substantially as shown in FIG. Although there are some differences in the shape due to the difference between the solids of the umbrellas, all the umbrellas expand around the umbrella axis A2, the umbrella cloth A4 expands radially, and the umbrella cloths A4 come into contact with each other around the umbrella bone A3. Only. In this state, the effects of "separation by centrifugal force" and "evaporation by heating" are easily exhibited.

[0009]

In order to dissolve the umbrella cloth A4 of the wet umbrella of FIG. 4 as shown in FIG. 5, if the umbrella cloth is rotated about the umbrella axis A2 in space, it can be easily released by centrifugal force. However, if the wet umbrella is placed in a dehydrating basket and rotated, the radial development of the umbrella cloth cannot be expected. In addition, if the umbrella is driven to rotate by input from the umbrella, the umbrella will be destroyed.

In the present invention, as shown in FIG. 1, the wet umbrella supports the stone end A1 and the tip of the umbrella bone A3, wraps the umbrella cloth A4 around with a vortex C1, and drives the umbrella to rotate like a windmill. Umbrella cloth A without disturbing umbrella
4 is unfolded, and the water droplet is separated from the umbrella cloth A4 by centrifugal force.

When the umbrella cloth A4 is unfolded, a groove-shaped space A5 shown in FIG. 5 is formed between the umbrella cloth and the umbrella cloth. When hot air is passed through the groove-shaped space, water is evaporated.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. A funnel-shaped lower rotation receiver 3 is provided on the bottom surface of the outer case 1 via a bearing 2 to hold the inserted umbrella butt A1. A donut-shaped upper rotation receiver 5 is provided on the upper surface of the outer box 1 via a roller 4, and the umbrella bone A3
The umbrella holding the tip of the umbrella is rotatable about the umbrella axis A2.

The umbrella is covered with a conical cylinder 6. A deceleration chamber 7 is provided below the conical cylinder 6, and an intake hole for a blower 9 is provided on a side surface thereof.

A heating chamber 10 is provided in a discharge hole of the blower 9. Inside, there are a heat storage heater 11 which maintains a high temperature even during non-dehydration and has a large heat capacity, and a main heater 12 which is operated only during dehydration. Between the heat storage heater 11 and the nozzle 14, there is provided a weight valve 13 which is closed by its own weight during non-dehydration and prevents the heated air from leaking.

The tip of the nozzle 14 is a conical cylinder 6 as shown in FIG.
And the eccentric amount is the position where the umbrella rotates at the highest speed.

The eccentric direction of the nozzle 14 can be changed, and
A pair of eccentric nozzles 14b and 14c may be provided as described above, and the umbrella may be rotated forward or backward by injecting an airflow from one of the nozzles.

Hereinafter, the actual operation will be described. Upper rotating receiver 5
When the umbrella is inserted through the hole and dehydration is started, the blower 9 and the main hitter 12 are energized simultaneously. The air in the heating chamber 10 pushes up the weight valve 13 and is jetted from the nozzle 14 into the conical cylinder 6. The injected air current flows along the inner wall of the conical cylinder 6 in a vortex C1.
And descend. The wet umbrella placed at the center of the conical cylinder 6 starts rotating as a windmill with the vortex C1.

When the rotation speed of the wet umbrella is 300 r. p. When it reaches about m, the umbrella cloth A4 that has been in close contact with the water B develops radially as shown in FIG. At that time, large water droplets of the umbrella having high water repellency are separated from the umbrella cloth A4.

When the rotation speed of the wet umbrella is 500 r. p. At about m, most of the water droplets of the highly water-repellent umbrella are separated. A part of the water film of the umbrella having low water repellency is detached, but most of the water film remains.

If the power of the blower 9 is increased, the rotation speed of the umbrella is increased and the dewatering effect is also increased. However, noise and vibration are increased accordingly. In addition, centrifugal force acts on the joints of the umbrella, which may cause damage to the umbrella. Since these are not preferable, the airflow is heated to evaporate the remaining water.

The water separated from the umbrella falls into the deceleration chamber 7 together with the vortex C1 and is discharged from the exhaust hole 15. A part of the airflow that has passed through the conical cylinder 6 is discharged to the outside together with the steam from the exhaust hole 15, and the remaining airflow passes through the grid 8, is sucked by the blower 9, and is sent to the heating chamber 10.

An air flow C2 that has cooled the inside of the blower motor is also sent to the heating chamber 10, and a considerable amount of exhaust flow C3 is added to this air flow.

The gas is discharged to the outside through the above described exhaust hole. Therefore, the circulating airflow is not saturated with water vapor.

The air flow pressurized by the blower 9 is reheated by the regenerative heater 11 and the main heater 12 and injected again into the conical cylinder 6 to maintain the rotation of the umbrella and at the same time maintain the water remaining on the umbrella cloth A4. While continuing evaporation, circulation is continued until a predetermined value is reached.

[0024]

According to the present invention, the umbrella cloth is radially developed by rotating the wet umbrella by vortex flow, so that the dewatering and dewatering of water by centrifugal force can be performed reliably.

The umbrella cloth can be dried by heating the vortex.

Since rotation, dehydration and drying are performed by an air current, the umbrella receives less external force during dehydration. Also, since the umbrella cloth does not come into contact with anything other than the airflow, there is no cause for soiling the umbrella.
