Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running water pool in which the flow velocity is variable in the direction opposite to the swimming direction.

[0002]

2. Description of the Related Art Conventionally, this type of running water pool is generally of a circulation type, and a uniform water flow is generated in a tank by forced circulation by a water flow generating propeller.

However, since a uniform water flow is generated over the entire tank portion, the required cost, required time, and required power are large, not only the equipment cost rises, but also it is difficult to set a desired flow velocity, and various shift patterns are required. There was a problem that could not be selected.

In addition, this type of running water pool has a problem that it is unsanitary because the pool water in the tank becomes distilled water when the pool is not used.

An object of the present invention is to deal with the use of all users from beginners to experts, and to make it hygienic regardless of whether the pool is used or not.

[0006]

[Means for Solving the Problems] The technical means taken to achieve the above-mentioned object is to open a circulation inlet and a circulation outlet at positions facing each other in the vicinity of a pool water surface of a tank wall, and to provide the circulation inlet. And a circulation outlet through a forced circulation device, and the forced circulation device has a normal forced circulation filtration means for communicating one end with the circulation outlet and the other end with the circulation jet part for circulation. One end is connected to the circulation outlet, and a multi-branch flow velocity changing jetting portion formed at the other end is connected to the circulation inlet and the flow velocity changing forced circulation means is provided with a pump motor on each branch. The jet portion for circulation is arranged in the center of the circulation inlet, and the jet portion for varying the flow velocity is arranged at appropriate intervals on both sides of the circulation jet on the same horizontal line as the circulation jet. A straightening vane was installed in front of the group A.

And the guide rods (4 ') for partitioning the flow passage at the inlet (8) at appropriate intervals.
It is formed by disposing a straightening plate (4) formed by erection of.

The forced circulation device (B) is a normal forced circulation filter means (b ₁ ) communicating with the circulation inlet (a ₂ ) and the circulation outlet (a ₃ ), a circulation inlet (a ₂ ) and a circulation outlet (b). a
₃ ) and the forced circulation means (b ₂ ) for varying the flow velocity.

The normal operation forced circulation filtration means (b ₁ ) is the other end of the forced circulation pipe (11) whose one end is connected to the most protruding end of the water receiving portion (7) constituting the circulation outlet (a ₃ ). That is, the circulation jetting part (1) (nozzle) communicates with the swimming part in the tub at the center of the lid (12) that closes the opening at the innermost end of the water guiding cylinder (9) in a watertight manner. The pump motor (2), the filtration tank (12) and the hair catcher (13) are connected in the middle of the forced circulation pipe (11).

The normal-action forced circulation filtration means (b ₁ ) functions to keep the pool water (in the swimming section) always clean by performing normal-action forced circulation regardless of whether the pool is used or not.

The forced circulation means (b ₂ ) for varying the flow velocity is branched from the forced circulation pipe (11) into a multi-branch from a main pipe (15) having a hair catcher (13) in the middle, and each branch is branched. A pump motor (2) is connected to the pipes (14), and each of the branch pipes (14) ... the flow velocity varying jet portion (3) at the other end.
(Nozzles) are connected to the portions of the lid (12) on both sides of the circulation jet (1) on the same horizontal line at appropriate intervals.

Further, each pump motor (2) of the forced circulation means (b ₂ ) for varying the flow velocity is an electric control panel (10).
The pump motor (2) can be selectively used by artificially pushing or touching the gear shift selection section.

Next, the operation of the running water pool in this embodiment will be described. The pump motor (2) of the normal-action forced circulation filtration means (b ₁ ) operates regardless of whether the pool is used or not,
Keep the pool water clean by filtering through the filtration tank (12) and hair catcher (13).

When using the pool, the electric control unit (1
Due to the artificial selection action of the shift selection unit in (0), among the flow velocity changing jetting units (3) in the flow velocity changing forced circulation means (b ₂ ) ... Operates the pump motor (2) connected to the ejection portions (3) (for varying the flow velocity) on both sides to obtain a desired flow velocity.

By the way, the jet flow ejected from each of the ejection portions (1) and (3) is a flow path partitioning guide rod (of the flow straightening plate (4) disposed at the inlet portion (8) of the circulation inlet (a ₂ ). 4 ') is rectified by 4') to generate sufficient surface water flow for swimming.

In this embodiment, a total of 5 jetting parts (1) and (3) are used.
Of course, the number is seven, but the number is seven or more. Of course, in that case, it is natural to provide the pump motor (2) on each branch pipe (14) having the ejection part (3) at the tip. Is.

[0020]

Since the present invention is constructed as described above, it has the following operational effects. (1) The forced circulation device is formed by a normal-action forced circulation filtration unit having one end connected to the circulation outlet and the circulation jetting unit at the other end connected to the circulation inlet, and one end connected to the circulation outlet and the other end. The multi-branch flow velocity changing jetting part is connected to the circulation inlet, and is composed of a flow velocity changing forced circulation means in which a pump motor is arranged in each branch, and the circulation jetting part is arranged at the center of the circulation inlet. In the circulation inlet, the flow velocity changing jetting portions are arranged at appropriate intervals on both sides on the same horizontal line as the circulation jetting portion, and the straightening plate is provided in front of the jetting portion group. A jet (jet stream) is jetted from each jet part, but is rectified by a straightening vane in the front, and the jet is converted into a surface superficial flow sufficient for swimming.

Therefore, the present invention has an advantage that various shift patterns characteristic of the nozzle system can be selected, and can generate a superficial flow having a substantially uniform width direction and a small velocity distribution in any shift pattern. It is possible to provide a running water pool that is most suitable for swimming practice even for experts.

(2) Since the forced forced circulation filtration means is provided, the pool water can be kept clean even when the pool is not used.

(3) Since the above-mentioned normal-action forced circulation filtration means can be used as the first speed (lowest speed) of the flow velocity pattern, there is no waste, and since the jet portion is arranged in the center of the circulation inlet, which speed It does not hinder swimming practice even with the gear shift pattern. Therefore, the intended purpose can be achieved.
