Description

Technical Field

[0001] This application relates to the field of swimming pool water treatment technology, and in particular to a swimming pool filtration system. Background Technology

[0002] Pool filtration systems are primarily used to regulate pool water quality, such as filtering impurities, removing sand, and adjusting salinity. In traditional pool filtration systems, a hose connects the outlet of a skimmer to the inlet of other treatment equipment, and then another hose connects the outlet of that equipment to a vent on the pool wall. This allows various filtration devices or water quality control equipment, such as skimmers, sand filters, and brine systems, to be connected to the pool filtration system.

[0003] However, for pool filtration systems that use tubeless skimmers, since the tubeless skimmer is directly connected to the inlet on the pool wall instead of through a hose, it is impossible to connect the outlet of the tubeless skimmer to other treatment equipment through a hose. Summary of the Invention

[0004] Therefore, it is necessary to provide a pool filtration system with a bypass device that can connect the tubeless skimmer to other treatment equipment via a hose, in order to address the problem that pool filtration systems using tubeless skimmers cannot connect the tubeless skimmer to other treatment equipment.

[0038] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0039] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Figure 17A schematic diagram of a prior art pool filtration system is shown, in which the outlet of a skimmer 91 is connected to a treatment device 30 via a hose 92, and the treatment device 30 is then connected to a water inlet 93 on the pool wall 90 via a hose 92. This connects the skimmer 91 and treatment devices 30, such as sand filters and brine systems, into the pool filtration system. A drawback of this approach is that, for pool filtration systems using a tubeless skimmer, since the tubeless skimmer is directly connected to the water inlet on the pool wall instead of via a hose, it is impossible to connect the outlet of the tubeless skimmer to other treatment devices via a hose.

[0042] Please refer to the above. Figures 1 to 4 This application provides a swimming pool filtration system, including a tubeless skimmer 10, a bypass device 20, and a treatment device 30. The tubeless skimmer 10 is connected in series with the bypass device 20 and the treatment device 30. In this embodiment, the tubeless skimmer 10 includes a housing 11 and a filter device 12 disposed within the housing 11. An inlet 111 and an outlet 112 are provided on the side of the housing 11 facing the pool wall 90, and the inlet 111 and outlet 112 are respectively inserted into and fixed to the water inlet 93 of the pool wall 90. In this embodiment, the filter device 12 includes a filter basket 121. The filter basket 121 is suitable for filtering out large-volume impurities such as fallen leaves. Optionally, the filter device 12 may also include other filtration structures, such as a filter element 122 (see reference). Figure 8 The filter basket 121 is used to filter out relatively small impurities. A water flow channel is formed inside the shell 11, with an inlet 111 and an outlet 112 located at opposite ends of the water flow channel. The filter basket 121 is disposed in the water flow channel. Water from the pool flows into the water flow channel through the inlet 111, is filtered by the filter basket 121 to remove large impurities such as fallen leaves, and finally flows back into the pool through the outlet 112.

[0043] exist Figures 1 to 4In the illustrated embodiment, the bypass device 20 is disposed at the bottom of the housing 11. Specifically, the bypass device 20 is fixed to the bottom of the housing 11 by a sealing nut 114. The bypass device 20 includes a main body 21, which forms the bottom wall of the housing 11. The bypass device 20 also includes a first water inlet connector 22, a first water outlet connector 23, a second water inlet connector 24, and a second water outlet connector 25 connected to the main body 21, wherein the first water inlet connector 22 and the first water outlet connector 23 are in fluid communication, and the second water inlet connector 24 and the second water outlet connector 25 are in fluid communication. Specifically, the first water inlet connector 22 and the second water outlet connector 25 protrude from the side of the main body 21 facing the interior of the housing 11. The first water inlet connector 22 is directly connected to and in fluid communication with the filter device 12 (e.g., filter basket 121), while the first water outlet connector 23 and the second water inlet connector 24 protrude from the side of the main body 21 away from the interior of the housing 11. The treatment device 30 is in fluid communication with the first water outlet connector 23 and the second water inlet connector 24, respectively. In this embodiment, the bypass device 20 further includes a connecting elbow 29. One end of the connecting elbow 29 is inserted into the second water outlet connector 25 and is in fluid communication with the second water inlet connector 24. The other end of the connecting elbow 29 is in fluid communication with the water outlet 112. Optionally, a sealing gasket is provided between one end of the connecting elbow 29 and the second water outlet connector 25. Optionally, a sealing gasket is provided between the other end of the connecting elbow 29 and the water outlet 112. The sealing gaskets are designed to ensure the waterproof sealing of the connections between one end of the connecting elbow 29 and the second water outlet connector 25, and between the other end of the connecting elbow 29 and the water outlet 112, ensuring that the water flowing into the treatment device 30 and the water flowing out of the treatment device 30 are isolated from each other. In other words, the water flows before and after treatment by the treatment device 30 will not mix. Reference Figure 4 , Figure 4The diagram schematically illustrates the flow direction of water in a pool filtration system according to an embodiment of this application. First, pool water enters the water flow channel within the housing 11 via the inlet 111. In the water flow channel, the pool water is filtered through the filter basket 121 to remove large impurities such as fallen leaves. The filtered pool water then enters a bypass device via the first inlet connector 22. Next, the pool water flows into the treatment device 30 from the first outlet connector 23. The pool water treated by the treatment device 30 returns to the bypass device via the second inlet connector 24. Finally, the pool water flows back into the pool from the outlet 112 of the housing 11 via the second outlet connector 25 and the connecting elbow 29. Thus, the pool filtration system according to an embodiment of this application completes the filtration and treatment of the pool water. In this embodiment, the tubeless skimmer 10 does not include a water pump; the power for the pool water flow in the pool filtration system comes from the water pump in the treatment device 30. Optionally, the treatment device 30 is a sand filter for removing sand particles. It is understood that the sand filter is only one optional device of the treatment equipment 30 according to this application. Those skilled in the art can choose other suitable treatment equipment 30 according to actual needs, as long as the treatment equipment 30 is connected to a water pump. Optionally, the treatment equipment 30 may include various types of treatment devices, such as sand filters and brine systems connected in series. In such an embodiment, at least one of the brine system and the sand filter is equipped with a water pump. After the pool water is pre-filtered by the tubeless skimmer 10, it flows into the sand filter and brine system through the bypass device 20 for further treatment, and finally flows back to the pool through the bypass device 20. In this way, a good filtration effect on the pool water is achieved. The sand filter and brine system mentioned in this application are treatment devices well known in the art, and those skilled in the art can choose a suitable treatment device according to their needs.

[0044] In the swimming pool filtration system provided according to the embodiments of this application, a treatment device 30, such as a sand filter, is connected to the swimming pool filtration system via a first outlet connector 23 and a second inlet connector 24 of a bypass device 20, and is connected in series downstream of the tubeless skimmer 10. This enables the tubeless skimmer 10 to be connected in series with other treatment devices 30, allowing the swimming pool filtration system using the tubeless skimmer 10 to be connected to other types of pool water treatment devices 30. Optionally, a water pump may also be installed in the tubeless skimmer 10, which will be described in detail later.

[0045] Figure 5 and Figure 6 Two alternative embodiments of the bypass device are shown. Figure 5 Compared to the embodiments shown, Figure 6The connecting elbow 29 of the bypass device 20 shown has a longer length in the vertical direction. It is understood that those skilled in the art can select a suitable length and outer diameter for the connecting elbow 29 according to actual needs, such as the dimensions of the housing 11 or the inner diameter of the second outlet connector 25. Optionally, in Figure 5 In the illustrated embodiment, slots (not shown) of different depths are provided in the second water outlet connector 25. The connecting elbow 29 is inserted into slots of different depths to achieve different vertical heights using the same connecting elbow 29. For example, inserting the connecting elbow 29 into a slot with a greater depth results in a lower vertical height; inserting it into a slot with a lesser depth results in a greater vertical height. Optionally, in other embodiments, the connecting elbow 29 is integrally formed with the housing 11. In such an embodiment, the housing 11, second water inlet connector 24, second water outlet connector 25, and connecting elbow 29 are an integral structure. The vertical height of the connecting elbow 29 is not adjustable, but the overall structure is simpler.

[0046] Please refer to the above. Figure 7 and Figure 8 In one embodiment of this application, the tubeless skimmer 10 further includes a water pump 13, which is disposed in the water flow channel of the housing 11 to provide power for the water flow through the pool filtration system. The filtration device 12 is in fluid communication with the first inlet connector 22 via the water pump 13, and the bypass device 20 is disposed between the outlet 112 and the pool wall 90. The outlet 112 is in fluid communication with the water inlet 93 on the pool wall 90 via the bypass device 20. In this embodiment, the filtration device 12 includes a filter basket 121 and a filter element 122. In the water flow channel, the filter basket 121 is disposed upstream of the filter element 122, and the two are in fluid communication. The filter basket 121 is used to filter out relatively large impurities, such as fallen leaves and packaging bags; the filter element 122 is used to filter out relatively small impurities. After being filtered by the tubeless skimmer 10, the pool water flows into the treatment equipment 30 through the outlet 112 and the bypass device 20. The pool water treated by the treatment equipment 30 flows back into the pool through the bypass device 20.

[0047] Please refer to the above. Figures 9 to 13The bypass device 20 also includes an outlet connector 26 and an inlet connector 27. Both the outlet connector 26 and the inlet connector 27 are connected to the main body 21. A first outlet connector 23 is formed on the outlet connector 26, and a second inlet connector 24 is formed on the inlet connector 27. In this embodiment, the main body 21 is configured as a generally cylindrical tubular structure, including a first mounting portion 211, a second mounting portion 212, and a third mounting portion 213 (see figure) connected sequentially along the axial direction of the main body 21. An inner hole 214 is formed within the main body 21, penetrating the first mounting portion 211, the second mounting portion 212, and the third mounting portion 213. A partition plate 215 is provided in the inner hole 214, dividing the portion of the inner hole 214 located within the first mounting portion 211 and the second mounting portion 212 into a first flow channel 2141 and a second flow channel 2142. The end of the first flow channel 2141 facing the first mounting portion 211 forms a first water inlet connector 22, and the first flow channel 2141 is in fluid communication with the first water outlet connector 23. The portion of the inner hole 214 located within the third mounting portion 213 and the first mounting portion 213 form a second water outlet connector 25, which is in fluid communication with the second flow channel 2142 and is inserted into the water inlet 93 of the pool wall 90 (see reference).

The water outlet connector 26 covers the first through hole 216. The first flow channel 2141 is in fluid communication with the first water outlet connector 23 through the first through hole 216. The water inlet connector 27 covers the second through hole 217. The second water inlet connector 24 is in fluid communication with the second flow channel 2142 through the second through hole 217.

[0049] refer to Figure 13 Optionally, the outlet connector 26 has a generally arc-shaped first connecting portion 261 that covers the first through hole 216 and approximately half of the outer circumference of the second mounting portion 212 in the circumferential direction of the main body 21. The inlet connector 27 has a generally arc-shaped second connecting portion 271 that covers the second through hole 217 and approximately the other half of the outer circumference of the second mounting portion 212 in the circumferential direction of the main body 21. The first connecting portion 261 and the second connecting portion 271 can be fixedly connected to each other by fasteners such as screws or nuts, and form a generally circular shape in the circumferential direction of the main body 21. Optionally, sealing gaskets 28 are provided between the first through hole 216 and the first connecting portion 261, and between the second through hole 217 and the second connecting portion 271.

[0050] Please refer to the above. Figure 11 , Figure 14 and Figure 15In one embodiment of this application, the first mounting part 211 is fixed to the outlet 112 of the housing 11 by a connecting nut 40. Specifically, a retaining edge 2111 is provided at the connection position between the first mounting part 211 and the second mounting part 212, and the retaining edge 2111 protrudes from the outer peripheral surface of the first mounting part 211 in a direction away from the first mounting part 211. On the side of the retaining edge 2111 away from the second mounting part 212, an insertion part 2112 is formed on the outer peripheral surface of the first mounting part 211, which can be inserted into the outlet 112. In this embodiment, an external thread 113 is provided on the outer peripheral surface of the outlet 112, and an internal thread 401 and a locking protrusion 402 are provided on the inner wall of the connecting nut 40. When the first mounting part 211 is installed to the outlet 112, the insertion part 2112 is first inserted into the outlet 112, and then the retaining edge 2111 is fixedly connected to the outlet 112 using the connecting nut 40. Specifically, firstly, the female part 410 and the male part 402 of the connecting nut 40 are simultaneously fastened onto the retaining edge 2111 and the insertion part 2112, so that the locking protrusion 402 is located on the side of the retaining edge 2111 facing the second mounting part 212; then, the locking tongue 4201 of the male part 402 is aligned and inserted into the slot 4101 of the female part 410, so that the female part 410 and the male part 402 are fixedly connected to form a ring-shaped connecting nut 40; the ring-shaped connecting nut 40 is screwed on, and through the threaded connection between the internal thread 401 and the external thread 113, the bypass device 20 is biased and moved towards the outlet 112 until the end face of the first mounting part 211 facing away from the second mounting part 212, that is, the end face of the first water inlet connector 22, is pressed against the outer surface of the outlet 112. At this time, the connecting nut 40 is screwed in place, and the first mounting part 211 is fixedly connected to the outlet 112. Optionally, a sealing gasket is provided between the end face of the first water inlet connector 22 and the outer surface of the water outlet 112 to ensure an effective waterproof seal. Alternatively, a sealing gasket may not be provided between the end face of the first water inlet connector 22 and the outer surface of the water outlet 112. In such an embodiment, the effectiveness of the waterproof seal is ensured by the end face of the first water inlet connector 22 directly pressing against the outer surface of the water outlet 112. It is understood that in embodiments where no sealing gasket is provided between the end face of the first water inlet connector 22 and the outer surface of the water outlet 112, the contact surfaces of the first water inlet connector 22 and the outer surface of the water outlet 112 can use suitable materials known in the art to increase the effectiveness of the waterproof seal.

[0051] The following is combined Figure 8 and Figure 16 Explanation in Figures 7 to 15 The illustrated embodiment shows the direction of water flow in the pool. Specifically, the pool water flowing into the housing 11 is filtered by the filter device 12 (see reference). Figure 8After passing through the water pump 13, the water enters the first inlet connector 22; the pool water flows through the first flow channel 2141 and the first outlet connector 23 to the treatment equipment 30; the pool water treated by the treatment equipment 30 flows through the second inlet connector 24 and the second flow channel 2142 in sequence; finally, the pool water flows back into the pool through the second outlet connector 25.

[0052] exist Figures 7 to 15 In the illustrated embodiment, the tubeless skimmer 10 includes a water pump 13, which provides the power for the flow of pool water. Therefore, the treatment device 30 may not include the water pump 13. Optionally, the treatment device 30 is for a brine system. It is understood that the brine system is only one optional device for the treatment device 30 according to this application, and those skilled in the art can choose other suitable treatment devices 30 according to actual needs. In the pool filtration system provided according to the embodiments of this application, the treatment device 30, such as a brine system, is connected to the pool filtration system via a first outlet connector 23 and a second inlet connector 24 of the bypass device 20, and is connected in series downstream of the tubeless skimmer 10. This enables the tubeless skimmer 10 to be connected in series with other treatment devices 30, allowing the pool filtration system using the tubeless skimmer 10 to be connected to other types of pool water treatment devices 30.
