In this context, the pool referred to may be an above-ground pool or an underground pool, wherein the above-ground pool includes, but is not limited to, an aerated pool, a rigid/foam pool, a cradle pool, and the like. "inner" refers to a direction toward the pond reservoir and "outer" refers to a direction away from the pond reservoir. "gas" refers to a gas stream such as air that may be input from the outside atmosphere or equipment, and "fluid" encompasses a fluid such as a gas stream and a water stream.

The waterway system provided by the utility model is illustrated by the following taking an aerated water tank as an example.

As shown in fig. 1, a waterway system for a pool of water according to the present utility model. The waterway system comprises a pipe system and a pump system 5 applied to the pool 1. It will be appreciated that although the pool 1 is circular in fig. 1, the pool 1 may have other shapes (e.g., without limitation, elliptical or square). For example, referring to FIG. 2, sink 1 is a square sink in accordance with the present utility model.

In particular, when the basin 1 is an aerated basin, in one embodiment, as shown in fig. 2, the basin 1 comprises a bottom 11 and a basin wall 12 surrounding said bottom 11, the bottom 11 and the basin wall 12 together delimiting a water storage area. A plurality of pull straps 13 are provided in the tank wall 12, evenly distributed in the annular inflatable layer at equal angular intervals with respect to the vertical central axis of the tank 1. The cell wall 12 includes an inner wall 121, an outer wall 122, a top sheet 123, and a bottom sheet 124. The top sheet 123 and the bottom sheet 124 are disposed at a top-bottom interval, the inner wall 121 and the outer wall 122 are disposed between the top sheet 123 and the bottom sheet 124, and an upper edge of each of the inner wall 121 and the outer wall 122 is connected to the top sheet 123 and a lower edge is connected to the bottom sheet 124.

A pipe system is provided in the tank wall 12. The pipeline system comprises a water outlet pipeline 2 and a water inlet main pipe 3 (the water outlet and inlet directions of the pipeline system are relative to the direction of the pool). Wherein the water outlet pipeline 2 passes through the pool wall 12 to communicate the water storage area with the pump system 5 and guide water in the water storage area to the pump system 5, and one end of the water outlet pipeline 2, which is communicated with the water storage area, is provided with a filtering device, namely the filtering device is positioned on the inner side of the pool wall 12 of the water pool 1 so as to realize a filtering function. Thus, the water in the basin 1 may be first filtered by the filter means and then introduced into the pump system 5.

The water inlet manifold 3 is connected to the water inlet of the flow dividing means 8 and divides the water into at least two branches, e.g. a first branch 31 and a second branch 32, by the flow dividing means 8. The first branch pipe 31 is arranged above the water outlet pipe 2 and communicates the flow dividing device 8 with the water storage area. The flow dividing means 8 comprise at least one water inlet and two water outlets. For example, the flow dividing means 8 is a three-way valve comprising a first water outlet and a second water outlet. The first water outlet of the diverting device is connected to the first branch pipe 31 and the second water outlet of the diverting device is connected to the second branch pipe 32. Of course, the pipe system may be provided with a plurality of branch pipes, and the number of outlets of the flow dividing device 8 corresponds to the number of branch pipes, which is not limited in the present utility model.

The second branch pipe 32 comprises a first branch pipe 321 and at least one connecting pipe 322 arranged in the tank wall 12. For example, the first branch pipe 321 is an annular pipe surrounding the inner wall 121. The first branch 321 comprises a first end and a second end opposite the first end, wherein the first end of the first branch 321 is connected to the flow dividing means 8. The connection pipe 322 extends from the wall of the first branch pipe 321, one end of the connection pipe 322 is connected to the second end of the first branch pipe 321, and the other end is provided with a massage spray nozzle 323 to achieve a water spray massage function. For example, the massage shower head is provided at one end of the connection pipe 322 extending to the inner wall 121. For example, when the first branch pipe 321 is disposed near the bottom 11 of the sump 1, two sets of two connection pipes 322 each may be disposed along the circumference of the inner wall 121, and the connection pipes 322 extend upward from the wall of the first branch pipe 321. Of course, the positions and the number of the connection pipes 322 are determined according to actual needs, and the present utility model is not limited thereto.

As shown in fig. 3 to 5, the housing of the pump system 5 includes an upper housing and a lower housing detachably connected, and a water pump 51 is provided in the housing. The water pump 51 comprises a water inlet pipe 511 and a water outlet pipe 512, the water inlet pipe 511 of the water pump 51 is connected with the water outlet pipeline 2 of the water tank 1, and the water outlet pipe 512 of the water pump 51 is connected with the water inlet main pipe 3.

The water pump 51 is provided with an impeller and a motor, the impeller is driven by the motor, and water in the water pump 51 flows radially around the impeller as a center to the outer edge. The machine is capable of operating in two modes providing at least two flows. For example, the motor includes a first mode for providing a first flow rate and a second mode for providing a second flow rate, and the first flow rate is greater than the second flow rate. Thus, when the motor is operated in the first mode, the flow rate of water in the water inlet manifold 3 increases relative to the flow rate of water in the second mode, and thus the flow rates of water in the first and second branch pipes 31 and 32 also increase. For example, the first mode is set to the high-speed mode, and the second mode is set to the low-speed mode.

In addition, a heater 513 may be provided in the water pump 51 to heat the water so as to make the temperature of the water in the water tank 1 appropriate.

When the motor is in a low-speed state, water driven by the impeller flows into the water inlet pipe 511 and the heater 513 of the water pump 51 sequentially through the filtering device and the water outlet pipeline 2 of the water tank 1, flows out of the water pump 51 through the water outlet pipe 512 of the water pump 51 and flows back to the water inlet main pipe 3. By the diversion of the diversion means 8, a part of the water is returned directly to the basin 1 via the first branch 31 and another part of the water is passed via the second branch 32 to the spray head 323 and through the spray head 323 into the basin 1. When the motor is in a high-speed state, the water outlet flow rate of the water pump 51 is increased, and the water outlet flow rate of the spray nozzle 323 is also increased, thereby realizing the massage and water spraying functions by the impact force of the water flow. Compared with the waterway system of the existing pond, the filtered water can not only return to the pond 1 through the first branch pipe 31, but also enter the pond through the spray heads 323 of the second branch pipe 32, so that the heated water flows into the pond from more directions, the water temperature in the pond is kept consistent, and the heating efficiency of the system is improved. Of course this feature is achieved in combination with a heater, for example a PTC (Positive Temperature Coefficient ) heater or a resistive heater. In addition, the filtered water flows into the water tank from more directions, so that the filtering efficiency of the system can be improved.
