[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pool water circulation / purification device.

[0002]

2. Description of the Related Art As a conventional pool water circulation / purification device, those shown in FIGS. 3 and 4 are known. This device is located at a relatively shallow water position on the four standing walls 2A, 2B, 2C, 2D of the pool 1, that is, 600 mm from the bottom surface 3
A plurality of discharge ports 4, 4 ... Are opened at the same level and at the same level, a suction port 5 is opened in the center of the bottom surface 3, and a hair catcher 6A and a circulation pump 6 are provided.
B, a filter 6C, a warmer (heat exchanger) 6D, a discharge side pipe 6E and a suction side pipe 6F constitute a pool water circulation / purification system 6, and the discharge side pipe 6E is connected to the discharge port 4, 4 ...
, And the suction side pipe 6F is connected to the suction port 5.

According to this type of pool water circulation / purification device, the pool water W is discharged by operating the circulation pump 6B → the discharge port of the circulation pump 6B → the filter 6C → the warmer 6D → The discharge side pipe 6E → a plurality of discharge ports 4, 4 ... → the suction port 5 → the suction side pipe 6F → the hair catcher 6A → the circulation pump 6B is circulated and purified through the suction port. But,
Since the plurality of outlets 4, 4, ... Are opened at the same level of each of the four standing walls 2A, 2B, 2C, 2D, mutual interference occurs in the discharged water flows, which hinders the flow. Therefore, the function of directing to the suction port 5 suspended matter (hereinafter referred to as foreign matter) such as hair or lint that needs to be entrained in the discharged water and the flow of discharged water to flow, and effective suction of foreign matter cannot be expected. Further, since the opening positions of the discharge ports 4, 4, ... Are set at a relatively high position of about 600 mm from the bottom surface 3, there is a high probability that the discharge water flow interferes with the swimmer and hinders the flow. Also reduces the suction efficiency of foreign matter. Moreover, since the flow area of the discharged water is the area where the pool water is violently and forcibly stirred by the swimmer, the forced agitation action also hinders effective suction of the foreign matter. Furthermore, in FIG.
The two corners form a dead water area surrounded by the standing walls 2A, 2B, 2C, 2D and the discharge water flow, and the water is settled. In addition, the foreign matter is apt to be unevenly distributed in the dead water area to prevent the flow to the suction port 5. ,
It reduces the suction efficiency. Therefore, the foreign matter that has settled on the bottom surface 3 during the non-use period of the pool (for example, at night) or the fine particle foreign matter that has been solidified and set by the chemical treatment is
It is necessary to perform a complicated work of collecting with a submersible robot or a submersible cleaner before using the tool.

On the other hand, there is also a pool water circulation / purification device shown in FIG. In this device, a plurality of outlets 4, 4, ... Are opened on the bottom surface 3 of the pool 1, and the outlets 4, 4 ,.
The discharge side pipe 6E of the water circulation / purification system 6 is connected, and the suction side pipe 6F is connected to the overflow drainage groove 7 adjacent to the upper end sides of the two standing walls 2C and 2D. ing.

According to this type of pool water circulation / purification device, the pool water W is discharged by operating the circulation pump 6B → the discharge port of the circulation pump 6B → the filter 6C → the warmer 6D → Discharge side pipe 6E → a plurality of discharge ports 4, 4 ... → overflow drainage groove 7 → suction side pipe 6F → hair catcher 6A → circulation / purification through the suction port of circulation pump 6B. . However, since the plurality of discharge ports 4, 4, ... And the discharge side pipe 6E must be attached to the bottom surface 3, the work is troublesome and the workability is poor. Therefore, the construction cost is high, which is economically disadvantageous, and there is a management difficulty that maintenance is difficult.

[0006]

Problems to be solved are various problems such as low suction efficiency of foreign matter, economical disadvantage due to high construction cost, and difficult maintenance.

The suction port and the discharge port are connected to each other by a pool water circulation / purification system, which improves the suction efficiency of foreign matter, reduces the construction cost and secures economic advantages, and maintenance. Achieved the purpose of facilitating.

[0008]

According to the present invention, since the flow pattern of the discharged water is only the forward flow from the discharge port to the suction port, mutual interference does not occur in the discharged water flow. In addition, since the opening position of the discharge port and suction port is set to a position where the depth of water is relatively deep near the bottom surface, foreign matter floating in the bottom surface of the pool and the pool is efficiently directed to the suction port by the discharge water flow. In addition, the discharge water flow has a low probability of interfering with the swimmer and obstructing the flow. Moreover, in the flow area of the discharge water,
The pool water is not vigorously and irregularly stirred by the swimmer. In addition, there is no dead water area where water settles at the four corners. Furthermore, since it is sufficient to install the discharge port and the suction port on the standing walls of the pool facing each other, the work is simplified and the workability is improved.
