Description

[Detailed Description of the Invention] This invention relates to an air venting device for a circulation duct in a swimming pool.

In a swimming pool, a circulation duct runs around the poolside, and the circulation duct communicates with the bottom of the pool tank via a predetermined filter and the side of the pool tank via a plurality of water supply pipes. The filtered water in the pool tank is sent to the circulation duct, and the water is recycled into the pool tank through the water supply pipe. It is necessary to clean the area.

Note that the circulation duct circulating around the poolside means that when the stored water in the pool tank that has been filtered through the filter is circulated back to the pool tank, it is connected to multiple water supply pipes opened at the bottom of the circulation duct. This is to ensure that the water circulates evenly and calmly through the pipes to the side walls of various parts of the pool tank.

However, as will be described later, this circulation duct causes air to accumulate in its space, but conventional circulation ducts do not have an appropriate means for removing such accumulated air. This disturbs the flow of circulating filtered water, generates noise, and otherwise interferes with the cleaning cycle of the stored water.

Therefore, the present invention was developed in view of the drawbacks of the conventional example, and a circulation duct 1 is circulated around the poolside, and the circulation duct 1 passes through a predetermined filter 2 to the bottom surface 4 of the pool tank 3. and multiple water supply pipes 5
The water connected to the side wall 6 of the pool tank 3 is communicated with the side wall 6 of the pool tank 3 through the filter 2, and the stored water in the pool tank 3 that has been filtered through the filter 2 is sent to the circulation duct 1. In a swimming pool equipped with a purifying device for stored water that circulates inside the swimming pool, the circulation duct 1
The filter 2 in the reflux duct 1 is connected to an intake pipe 7 which has both ends opened at the upper end of the inner space and the side wall 6 of the pool tank 3 and communicates between the upper end of the inner space of the reflux duct 1 and the inside of the pool tank 3. This device consists in an air venting device for a circulation duct in a swimming pool, which is installed at the farthest position from the supply port 8 of filtered water that is sent out through the circulation duct 1. The purpose is to efficiently remove air using the above-mentioned simple air venting device, normalize the flow of filtered water sent into the circulation duct 1, and ensure a proper and smooth circulation cycle of the stored water purification device. .

Hereinafter, a typical embodiment of the present invention will be described in detail based on the drawings. The drawing shows an aluminum board pool.

FIG. 1 is a cross-sectional view, in which the pool tank 3 is filled with stored water through a source water supply pipe 9, and is taken out from a discharge port 10 provided on the bottom surface 4 of the pool tank 3 through a pipe 11.
After passing through the filter 2 and filtering it into a certain amount of clean water, it is sent to the feed pipe 12, sent out from the supply port 8 into the circulation duct 1, and passed through the water supply pipe 5 into the pool tank 3. The pool tank 3 is recirculated, and the pool tank 3 is filtered to a certain level of clean water through the circulation cycle of the cleaning device, thereby maintaining hygiene of the swimming pool.

As shown in FIG. 3, the water supply pipe 5 and the intake pipe 7 are L-shaped pipes, and the circulation duct 1 and the pool tank 3
As mentioned above, the water supply pipe 5 has both ends opened at the lower surface inside the circulation duct 1 and the side wall 6 of the pool tank 3, and the filtered water sent to the circulation duct 1 is transferred to the pool tank 3. It circulates to. Like the water supply pipe 5, the intake pipe 7 has one end opened in the side wall 6 of the pool tank 3, and the other end penetrates the bottom wall of the circulation duct 1 in a liquid-tight manner and extends to the lower surface of the top wall. The intake port 13, which is concave when viewed from the side, is formed on the edge and serves as an opening to the upper end of the internal space of the circulation duct 1.As will be described below, the accumulated air floating in the upper part of the circulation duct 1 can be effectively removed from the intake port 13. The water is discharged from the tank to the pool tank 3. In the figure, reference numeral 14 is a pump, 15 is an overflow duct, 1
6 is a drainage pipe.

Figure 2 is a plan view, showing that the filtered water sent out from the supply port 8 flows bifurcated in the direction of the arrow along the circulation duct 1 that goes around the poolside, and multiple water supplies are arranged at equal intervals. The water is circulated through the pipe 5 almost evenly to various parts of the pool tank 3. One intake pipe 7 is provided at a position farthest from the filtered water supply port 8 in the circulation duct 1.

FIG. 3 is a partially enlarged view showing that when the filter 2 is not in motion, the filtered water in the circulation duct 1 maintains the same water level as the water stored in the pool tank 3 communicating with the water supply pipe 5. In this state, the space A in the circulation duct 1 is filled with accumulated air. Air is sucked into the space A of the circulation duct 1 from the connections of various piping parts, etc. during a backwashing operation in which the filter 2 is reversed and the internal filter is washed with backflow energy of filtered water.

Now, in Fig. 1, when the filter 2 is started,
Inside the circulation duct 1, filtered water is sent from the filter 2 to the supply port 8 with considerable pressure, and the inside of the circulation duct 1 is sequentially filled with filtered water from the supply port 8 side as shown in Fig. 2. flow in the direction. Therefore, the air that had accumulated in the circulation duct 1 before the operation of the filter 2 is compressed and concentrated in the part of the circulation duct 1 that is farthest from the filtrate water supply port 8. be.

Therefore, the intake pipe 7 provided at that position
The accumulated air is discharged to the pool tank 3 by overcoming the pressure difference due to the water head with the water level in the pool tank. In other words, the reflux duct 1 is discharged from the filter 2 under considerable pressure.
The filtered water sent into the pool flows back into the pool tank 3 sequentially through a large number of water supply pipes 5, and at the same time, the part of the circulation duct 1 where the intake pipe 7 furthest from the filtered water supply port 8 is provided. The accumulated air is moved to overcome the accumulated water pressure in the pool tank 3 and the intake pipe 7, and the accumulated air is pushed out through the intake pipe 7 into the pool tank 3.

The filtered water flowing through the circulation duct 1 is rippled, but since the filtered water flows from the supply port 8 side while filling the circulation duct 1 in sequence, the accumulated air is pushed toward the intake pipe 7 side, and the filtered water It is sucked into the intake port 13 and discharged into the pool tank 3 earlier than that, and in the final stage, it is discharged into the pool tank 3 together with the filtered water flowing into the intake pipe 7.

Thus, once the evacuation of the trapped air is completed,
During operation of the filter 2, the entire circumference and entire cross section of the circulation duct 1 is completely filled with filtered water and flows sequentially, and the water level in the circulation duct and the water level in the pool tank are no longer the same. Air no longer flows into the circulation duct 1 again, and the flow of the filtered water becomes smooth thereafter. Therefore, in this state, the intake pipe 7 mainly circulates filtered water to the pool tank 3 in the same way as the water supply pipe.

However, when the filter 2 is temporarily stopped and the reverse cleaning operation is performed, the filter 2 sucks air, and when the filter 2 is restarted, air is sent into the circulation duct 1. This cycle causes air to be immediately removed to the pool tank.

As explained above, the air release device for the circulation duct of the present invention circulates around the circulation duct on the poolside, and the circulation duct is connected to the bottom of the pool tank via a predetermined filter and to the bottom of the pool via a plurality of water supply pipes. A purifying device for stored water that communicates with a side wall of the pool tank, sends the stored water in the pool tank filtered through the filter into a circulation duct, and circulates it back into the pool tank through the water supply pipe. In the swimming pool equipped with the above-mentioned swimming pool, an intake pipe having both ends opened at the upper end of the circulation duct inner space and the side wall of the pool tank and communicating between the upper end of the circulation duct inner space and the inside of the pool tank is connected to a filtration pipe in the circulation duct. It is arranged at the farthest position from the supply port for filtered water sent out through the machine. Therefore, the accumulated air floating in the circulation duct is naturally pushed to the above-mentioned specific part in the circulation duct when the filter starts, and is discharged to the outside through the intake pipe of the present invention. This makes the flow of filtered water sent into the circulation duct smooth and smooths the circulation cycle of the stored water purification device. Problems such as turbulence and pulsation in the filtered water that flows sequentially through the duct, noise, damage to pipe connections, and obstruction to the uniform circulation of the filtered water through each water supply pipe are completely eliminated. That's what happens. Furthermore, the configuration is extremely simple, and it can be said that this is a rational air venting device that focuses on the characteristics of the swimming pool cleaning device.
