Description

[Detailed Description of the Invention] The present invention relates to a swimming pool water purification device using a pump.

FIG. 1 shows a conventional device of this type, in which a pool 1 is provided with a pool water suction port 2, and the suction port 2 is connected to the suction side of a pump 4 through a suction flow path 3. 4
The discharge side thereof is connected to a Libourg water discharge port 6 through a discharge flow path 5.

Further, the discharge flow path 5 has a drainage flow path 7 provided with a drainage gate valve 8.
are connected.

By driving the pump 4, the pool water flows in the direction of the arrow, and the pool water is circulated and purified or drained. However, if someone approaches the pool water suction port 2 while the pump is operating, they will be drawn in by the suction force of the pump. Furthermore, when the pool water suction port 2 is completely adsorbed, the suction force of the pump becomes maximum, and the self-scissor cannot escape from it, which has the disadvantage of eventually leading to personal injury.

Therefore, it is an object of the present invention to provide a swimming pool purifying device that can suppress as much as possible the increase in adsorption force applied to foreign matter such as human bodies at the pool water suction port when the pool water suction port is blocked.

The swimming pool purification device according to the present invention includes an auxiliary water tank having an atmospheric opening above the pool water surface in the middle of the flow path located below the pool water surface between the pool water suction port and the pump, and the auxiliary water tank and at least two or more locations. The respective independent pool water suction ports are communicated with each other through a flow path.

Therefore, even if one pool water suction port is blocked, the pump will suck water from the other pool water suction ports, and the suction power of the blocked suction port will be extremely weak, which may cause human beings to fall under the suction effect. There will be no need to escape.

Therefore, by implementing the present invention, it is possible to prevent personal injury caused by the suction force of the pump.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The purification device includes a filter between the pool water suction port and the pump, a filter between the hair collector pump and the pool water discharge port, and a sterilizer. Although these are normally installed, they are not shown because they are not directly related to the present invention.

Therefore, the swimming pool purification device according to the present invention can be implemented as a drainage device.

2 and 3 show an embodiment of the present invention. In these figures, the same parts as in FIG. 1 are designated by the same reference numerals, and their explanation will be omitted.

In the embodiment of the present invention shown in FIG. 2, an auxiliary water tank 9 is provided at a portion of the suction flow path 3 that is lower than the pool water level A, and this auxiliary water tank 9 is opened to the atmosphere at a portion of the water surface A that is higher than the normal water level. ing.

The auxiliary water tank 9 is communicated with two independent pool water suction ports 2', 2'' through independent channels 3', 3''.

Therefore, during pump operation, the pool water suction ports 2', 2''
is normally opened, the water level B in the auxiliary tank 9 is lower than the pool water level A by a height corresponding to the pressure loss due to the flow velocity between the pool water suction ports 2', 2'' and the auxiliary tank 9. However, due to the height difference, the water surface B in the auxiliary water tank 9 becomes stable, and the pump 4 continues to operate normally.

If one pool water suction port, for example, pool water suction port 2', is blocked, the height difference will increase, but pool water will still be sucked in from the other pool water suction port 2'', which is open. The height difference does not increase beyond a certain level.

At this time, the adsorption force of an obstructed object such as a body to the pool water inlet is (pool water inlet area) x (water pressure corresponding to the height difference after adsorption), and the conventional device shown in Fig. 1 Adsorption power (
Pool water suction port area) x [(maximum pump suction pressure) + (
This is much smaller than the water pressure (corresponding to the height from the pool water surface to the pool water inlet).

Also, almost the same effect can be obtained even if the auxiliary water tank 9 is sealed, but when the auxiliary water tank 9 is sealed, the suction force instantly becomes equivalent to the height difference, but when the auxiliary water tank 9 is opened to the atmosphere, There is a time interval before there is a difference in height.

That is, the suction force gradually increases, and therefore, during this period, it is easier for the blade to escape than when the blade is sealed.

In addition, in order to reduce the height difference, the pool water inlet 2
The pressure loss due to the flow velocity between the pool water suction ports 2', 2'' and the auxiliary water tank 9 can be reduced by, for example, bringing the pool water suction ports 2', 2" and the auxiliary water tank 9 closer together.

Furthermore, if three or more pool water suction ports are provided and communicated with the auxiliary water tank through three or more channels, the adsorption force can be further weakened.

FIG. 3 shows another embodiment of the present invention, in which there are three independent pool water inlets 2'.

2'' 2 nt provided, its pool water inlet 2', 2''.

2'' is connected to the auxiliary water tank 9 through a flow path 3', 3'' 3 nt9, and a flow path 3 that combines them.

The operation is the same as in the previous embodiment.

For example, in the case of a conventional device, if the maximum suction height of the pump is 8 m, and the height from the pool water surface to the pool suction port is 2 m, the adsorption force is equivalent to 10 skins.

However, with the device of the present invention, the height difference after adsorption is 0.5 m,
In this case, compared to the conventional device, (0,
The adsorption force is reduced to 5yrL/1077L) = (1/20).

As explained above, the present invention makes it possible to escape with the blade even if a person or the like is attracted to the pool water inlet, and is extremely effective for the safety of swimming pools.
