Description

Technical Field

[0001] This utility model belongs to the technical field of water temperature regulation equipment, specifically relating to a multi-temperature zone intelligent control pool water temperature equalization device. Background Technology

[0002] Swimming pools are dedicated spaces for people to engage in swimming activities or competitions. Most swimming pools are built on land and can be categorized into regular swimming pools and heated swimming pools based on water temperature. They are also available in indoor and outdoor configurations. The purpose of heated swimming pools is to reduce heat loss from the swimmer's body and prevent discomfort caused by a sudden drop in body temperature; the water temperature is generally maintained at around 28 degrees Celsius.

[0003] Common heated swimming pools typically use boilers or electric heating systems, along with pumps, to circulate the water between the pool and the heat exchanger, achieving a heating effect. However, this whole-area circulation heating mode heats the pool water as a whole through a single heat source and then forces the water to flow evenly through a circulation pump. But due to environmental factors (such as differences in lighting, the location of the water inlet, and insufficient water flow), pools are prone to forming localized areas of low or high temperatures. Whole-area circulation makes it difficult to precisely regulate the water temperature in specific areas, leading to a decline in user experience. At the same time, whole-area heating requires continuously maintaining the temperature of the entire pool water, and even if only a local area needs to be heated, it still consumes a lot of energy, resulting in resource waste. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-temperature zone intelligent control pool water temperature equalization device. The whole system uses the control unit to coordinate the control of each first and second electric control valve, so that the water temperature fluctuation in each area of ​​the pool is always controlled within a small range, and can target heating only in local low temperature areas, realizing multi-temperature zone intelligent control. Compared with the traditional whole-area circulation mode, it can effectively save energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-temperature zone intelligent control pool water temperature equalization device, comprising a pool, an installation chamber surrounding the pool, a cover plate on the top of the installation chamber, a suction unit installed through and fixedly mounted between one inner wall of the pool and the installation chamber, and a heating recirculation unit installed through and fixedly mounted between the other inner wall of the pool and the installation chamber. The suction unit includes a first cover, a first guide plate installed on the inner side of one end of the first cover, and a first temperature sensor installed on the inner side of the first cover. One end of the heating and reflux unit is connected to a first connecting pipe, one end of the first connecting pipe is connected to a first electrically controlled valve, one end of the first electrically controlled valve is connected to a confluence pipe group, one end of the confluence pipe group is connected to a filter device, the heating and reflux unit includes a second cover, a second guide plate is fixedly installed on the inner side of one end of the second cover, one end of the second cover is connected to a fourth connecting pipe, one end of the fourth connecting pipe is connected to a heating unit, one end of the heating unit is connected to a second electrically controlled valve, one end of the second electrically controlled valve is connected to a diversion pipe group, and one end of the diversion pipe group is connected to a filter device.

[0006] The beneficial effects of this invention are as follows: This device achieves precise temperature balance in different areas through distributed sensing and a dynamic circulation system. Water from low-temperature areas is extracted by the corresponding suction unit and input into the confluence pipe group. The water is then filtered by a filtration device, and the filtered water flows into the distribution pipe group. The second electrically controlled valve corresponding to the heating return unit at the corresponding location is opened. The fifth connecting pipe and the second three-way pipe of the distribution pipe group work together to distribute the water flowing into the distribution pipe group, allowing the water to enter the heating unit connected to the corresponding heating return unit through the opened second electrically controlled valve. The electric heating element is then turned on to heat the water in the heating chamber. During this process, the opening degree of the second electrically controlled valve is dynamically adjusted according to the temperature difference between each temperature zone, ensuring precise flow of the water to be heated. Inside the heating chamber of the heating unit, a second temperature sensor monitors the water temperature in real time and feeds it back to the control unit. The control unit then controls the electric heating tubes to perform a stepped heating process based on the real-time feedback from the second temperature sensor. The return pump then uses a fourth connecting pipe to evenly inject the heated water from the heating chamber into the low-temperature area of ​​the pool via a second guide plate. The one-way valve prevents water from flowing into the heating chamber from the pool, eliminating backflow interference between hot and cold water. The entire system uses the control unit to coordinate the control of each first and second solenoid valve, ensuring that water temperature fluctuations in each area of ​​the pool are always kept within a small range. It can also target heating only in local low-temperature areas, achieving intelligent multi-temperature zone control. Compared to the traditional full-area circulation mode, this effectively saves energy.

[0007] To facilitate heat transfer from the power module:

[0008] As a further improvement to the above technical solution: multiple suction units and heating reflux units are provided, and they are all arranged in a straight line along the inner sidewall of the pool.

[0009] The beneficial effects of this improvement are: each set of suction units in this device forms a combination with a set of heating and reflux units aligned with it, acting on a separate area, thereby realizing multi-temperature zone temperature control.

[0010] To cool the second heat-conducting plate:

[0011] As a further improvement to the above technical solution: the merging pipe group includes a first tee pipe connected to the first solenoid valve, a second connecting pipe connecting two adjacent first tee pipes, one end of the first tee pipe located at one end of the merging pipe group is connected to a suction pump, a plug is provided on the inner side of one end of the first tee pipe located at the other end of the merging pipe group, one end of the suction pump is connected to a third connecting pipe, and one end of the third connecting pipe is connected to a filter device.

[0012] The beneficial effects of this improvement are as follows: the water flow drawn from the pool through each suction unit enters the second connecting pipe through the first three-way pipe and merges, and is then drawn out by the suction pump and transported to the third connecting pipe, where it enters the filter device for filtration.

[0013] For air circulation and further sealing of the power module:

[0014] As a further improvement to the above technical solution: the diversion pipe group includes a second three-way pipe connected to the second solenoid valve, a fifth connecting pipe connecting two adjacent second three-way pipes, one end of the second three-way pipe located at one end of the diversion pipe group is connected to a sixth connecting pipe, a plug is provided on the inner side of one end of the second three-way pipe located at the other end of the diversion pipe group, and one end of the sixth connecting pipe is connected to the filter device.

[0015] The beneficial effects of this improvement are as follows: after the water flows in from the sixth connecting pipe, it flows in the second and third connecting pipes and the fifth connecting pipe, and is distributed to each heating chamber through the second and third connecting pipe. The plug can seal one end of the separation pipe group to prevent water leakage.

[0016] For the control of this device:

[0017] As a further improvement to the above technical solution: the filtration device includes a filtration chamber, a filter screen mounting plate is screwed onto the top of the filtration chamber, a sealing ring is provided on the outer side of the filter screen mounting plate, a filter screen frame is screwed onto the bottom of the filter screen mounting plate, and a filter screen is provided on the inner side of the filter screen frame.

[0018] The beneficial effects of this improvement are as follows: the filter screen screw mounting plate is fixed to the filter chamber by screws. By unscrewing the screws, the filter screen screw mounting plate can be taken out upwards and removed together with the filter screen frame, which makes it convenient to clean and replace the filter screen.

[0019] For the placement and charging of the charging gun:

[0020] As a further improvement to the above technical solution: the heating unit includes a heating chamber, a reflux pump is installed at one end of the heating chamber, a one-way valve is installed at one end of the reflux pump, one end of the one-way valve is connected to a fourth connecting pipe, a second temperature sensor and an electric heating tube are installed on the inner side of the heating chamber, and one end of the heating chamber is connected to a second electric control valve.

[0021] The beneficial effects of this improvement are as follows: the water drawn from the pool enters the heating chamber after filtration. The second temperature sensor monitors the water temperature inside the heating chamber in real time and feeds it back to the control unit. The control unit controls the electric heating tube to perform step-by-step heating under the real-time feedback of the second temperature sensor. The return delivery pump then injects the warm water heated by the heating chamber into the low-temperature area of ​​the pool through the fourth connecting pipe and the second guide plate. The one-way valve can prevent water in the pool from flowing into the heating chamber and eliminate the interference of hot and cold water backflow.

[0022] For the control of this device: as a further improvement to the above technical solution: a control unit is provided inside the installation compartment, and the control unit is electrically connected to the first electric control valve, the suction pump, the second electric control valve, the return delivery pump, the second temperature sensor, and the electric heating tube.

[0035] This device achieves precise temperature balance in different areas through distributed sensing and a dynamic circulation system. Water from low-temperature areas is extracted by the corresponding suction unit 2 and fed into the confluence pipe group. The water is then filtered by the filter device 14, and the filtered water flows into the branch pipe group. The second electrically controlled valve 25 corresponding to the heating return unit 20 at the corresponding location is opened. The fifth connecting pipe 27 and the second three-way pipe 26 of the branch pipe group work together to distribute the water flowing into the branch pipe group, allowing the water to enter the heating unit 24 connected to the corresponding heating return unit through the opened second electrically controlled valve 25. The electric heating element 33 is then turned on to heat the water in the heating chamber 29. During this process, the opening of the second electrically controlled valve 25 is dynamically adjusted according to the temperature difference between each temperature zone, ensuring that the required amount of water is precisely directed into the heating chamber 29 of the heating unit 24. Inside the heating chamber 29, the second temperature sensor 32 monitors the water temperature in real time and feeds it back to the control unit 34. The control unit 34 controls the electric heating tube 33 to perform step-by-step heating based on the real-time feedback from the second temperature sensor 32. The return pump 30 then uses the fourth connecting pipe 23 to evenly inject the warm water heated by the heating chamber 29 into the low-temperature area of ​​the pool through the second guide plate 22. The one-way valve 31 prevents water in the pool from flowing into the heating chamber 29, eliminating the interference of hot and cold water backflow. The entire system uses the control unit 34 to coordinate the control of each first electric valve 9 and the second electric valve 25, so that the water temperature fluctuation in each area of ​​the pool is always kept within a small range. It can also target heating only in local low-temperature areas, realizing multi-temperature zone intelligent control. Compared with the traditional full-area circulation mode, it can effectively save energy consumption.

[0036] Multiple suction units 4 and heating reflux units 20 are provided, and they are arranged in a straight line with equal spacing along the inner sidewall of the pool 1.

[0037] Each suction unit 4 of this device is combined with a set of heating reflux units 20 aligned therewith to form a single area, thereby achieving multi-temperature zone temperature control.

[0039] The water flow drawn from the pool 1 through each suction unit 4 enters the second connecting pipe 11 through the first three-way pipe 10 and merges. It is then drawn out by the suction pump 12 and transported to the third connecting pipe 13, and enters the filter device 14 for filtration.

[0040] The diversion pipe assembly includes a second tee pipe 26 connected to the second solenoid valve 25, a fifth connecting pipe 27 connecting two adjacent second tee pipes 26, one end of the second tee pipe 26 located at one end of the diversion pipe assembly is connected to a sixth connecting pipe 28, a plug is provided on the inner side of one end of the second tee pipe 26 located at the other end of the diversion pipe assembly, and one end of the sixth connecting pipe 28 is connected to the filter device 14.

[0041] After the water flows in from the sixth connecting pipe 28, it flows in the second three-way valve 26 and the fifth connecting pipe 27, and is distributed into each heating chamber 29 through the second three-way valve 26.

[0043] The filter screen mounting plate 16 is fixed to the filter chamber 15 by screws. By unscrewing the screws, the filter screen mounting plate 16 can be taken out upwards, along with the filter screen frame 18, making it convenient to clean and replace the filter screen 19.

[0044] The heating unit 24 includes a heating chamber 29. A reflux pump 30 is installed at one end of the heating chamber 29. A one-way valve 31 is installed at one end of the reflux pump 30. One end of the one-way valve 31 is connected to a fourth connecting pipe 23. A second temperature sensor 32 and an electric heating tube 33 are installed on the inner side of the heating chamber 29. One end of the heating chamber 29 is connected to a second electric control valve 25.

[0045] Water drawn from pool 1 is filtered and then enters heating chamber 29. Second temperature sensor 32 monitors the water temperature inside heating chamber 29 in real time and feeds it back to control unit 34. Control unit 34 controls electric heating tube 33 to perform step heating under the real-time feedback of second temperature sensor 32.

[0048] Working principle and usage process of this utility model:

[0049] This device achieves precise temperature balance in different areas through distributed sensing and a dynamic circulation system. Its core working principle is based on a closed-loop regulation network formed by symmetrically distributed suction units 4 and heating / recirculation units 20 on the inner and outer sides of pool 1. Each suction unit 4 is paired with an aligned heating / recirculation unit 20, acting on a specific area. A first temperature sensor 7 monitors the water temperature in this area and feeds the temperature value back to the control unit 34. When the control unit 34 detects that the water temperature in a certain area, as reported by the first temperature sensor 7, is below a set threshold, it immediately controls the corresponding suction units... The first electrically controlled valve 9 connected to Yuan 4 opens, and the suction pump 12 is started. The low-temperature water is drawn into the first connecting pipe 8 after passing through the turbulence optimization design of the first guide plate 6. It then flows through the parallel convergence of the first tee pipe 10 and the second connecting pipe 11 in the confluence pipe group, and is transported to the filter device 14 through the third connecting pipe 13. The filter screen inside the filter frame 18 can block and filter suspended dirt particles in the water, thereby purifying the water in the pool 1. The filtered water then flows into the diversion pipe group through the sixth connecting pipe 28, and controls the second electrically controlled valve 25 corresponding to the heating return unit 20 at the corresponding position to open. The fifth connecting pipe of the diversion pipe group... Connector 27 and the second three-way pipe 26 work together to distribute the water flowing into the diversion pipe group, allowing the water to flow through the opened second electrically controlled valve 25 into the heating unit 24 connected to the corresponding heating return unit. The electric heating element 33 is then turned on to heat the water in the heating chamber 29. During this process, the opening of the second electrically controlled valve 25 is dynamically adjusted according to the temperature difference between each temperature zone, ensuring that the required amount of water is precisely directed into the heating chamber 29 of the heating unit 24. The second temperature sensor 32 monitors the water temperature inside the heating chamber 29 in real time and feeds it back to the control unit 34. The control unit 34 then controls the electric heating element 33 to operate at the second temperature sensor 33. The system provides step-by-step heating based on real-time feedback from the heating chamber 29. The return pump 30 then uses the fourth connecting pipe 23 to evenly inject the heated water from the heating chamber 29 into the low-temperature zone of the pool via the second guide plate 22. The one-way valve 31 prevents water from flowing into the heating chamber 29 and eliminates backflow interference between hot and cold water. The entire system uses the control unit 34 to coordinate the control of each first solenoid valve 9 and the second solenoid valve 25, ensuring that the water temperature fluctuations in each area of ​​the pool are always kept within a small range. It can also target heating only in local low-temperature zones, achieving multi-temperature zone intelligent control. Compared with the traditional full-area circulation mode, this can effectively save energy.
