A warm/cold double-circulation water filter system and swimming pool arrangement includes a swimming pool separated into two pools, each pool having a water outlet and a plurality of water inlets, a double-circulation water filter system adapted to treat water circulated through the pools of the swimming pool, the double-circulation water filter system including a first filter unit, a second filter unit, and a heater, and a water pipe system adapted to deliver water from the water outlet of each of the pools of the swimming pool to the water inlets of each of the pools of the swimming pool through the double-circulation water filter system, the water pipe system having valve means selectively controlled to let water pass from the first filter unit and second filter unit of the double-circulation water filter system to the water inlets of the pools of the swimming pool via the heater.
Description
- The present invention relates to swimming pools and, more specifically, to a double-circulation water filter system and swimming pool arrangement, which enables warm and/or cold water to circulate through two separated pools of the swimming pool via a double-circulation water filter system.
- Regular swimming pools are commonly designed for circulation of cold water through a single-circulation water filter system. FIG. 1 shows the arrangement of a swimming pool and single-circulation water filter system according to the prior art. A swimming pool of this design is suitable for use in summer season only. There are also known swimming pools for circulation of warm water. However, some people would not like to swim in warm water even in winter season. According to conventional designs, it is expensive to build a swimming pool for cold water and a swimming pool for warm water. Further, building two swimming pools requires a big land area.
- The present invention has been accomplished to provide a warm/cold double-circulation water filter system and swimming pool arrangement, which separates the swimming pool into two pools for enabling warm/cold water to be respectively circulated through the pools of the swimming pool via a respective water filter unit. It is another object of the present invention to provide a warm/cold double-circulation water filter system and swimming pool arrangement, which enables warm/cold water to be selectively circulate through the two pools of the swimming pool. The warm/cold double-circulation water filter system and swimming pool arrangement of the present invention comprises a swimming pool separated into two pools, each pool having a water outlet and a plurality of water inlets, a double-circulation water filter system adapted to treat water circulated through the pools of the swimming pool, the double-circulation water filter system including a first filter unit, a second filter unit, and a heater, and a water pipe system adapted to deliver water from the water outlet of each of the pools of the swimming pool to the water inlets of each of the pools of the swimming pool through the double-circulation water filter system, the water pipe system having valve means selectively controlled to let water pass from the first filter unit and second filter unit of the double-circulation water filter system to the water inlets of the pools of the swimming pool via the heater.
- FIG. 1 illustrates the arrangement of a swimming pool and a single-circulation cold-water filter system according to the prior art.
- FIG.2 illustrates a warm/cold double-circulation water filter system and swimming pool arrangement according to the present invention.
- FIG. 3 illustrates water circulation paths through the two pools of the swimming pool according to the present invention.
- FIG. 4 illustrates the arrangement of the double-circulation water filter system and the water pipe system according to the present invention.
- Referring to FIG. 2, a swimming pool1 comprises a
partition wall 20. Thepartition wall 20 is comprised of a plurality ofround pots 22 andpartition boards 24, and separates the swimming pool 1 into two separated pools, namely, thefirst pool 12 and thesecond pool 14. Thepools water outlet water inlets round rods 22 are fixedly perpendicularly fastened to the bottom wall of the swimming pool 1, and aligned in a line between the two endwalls of the swimming pool 1 (i.e., in parallel to the two sidewalls of the swimming pool 1). Eachround post 22 has twolongitudinal coupling grooves 222 disposed at two sides. Thepartition boards 20 are respectively coupled to thecoupling grooves 222 of theround posts 22. Theround posts 22 are preferably mad of stainless steel. Thepartition boards 24 are made of material of high tensile strength. Thepartition wall 20 prevents circulation of water between thepools - Referring to FIGS. 3 and 4 and FIG. 2 again, the present invention further comprises a double-circulation
water filter system 3, and awater pipe system 4. The double-circulationwater filter system 3 comprises two filter units, namely, thefirst filter unit 30 and thesecond filter unit 40, and aheater 50. Thefilter units filter tank chlorinator chemical dispenser hair remover 38 or 48, and are controlled to filter and sterilize water passing through. Thewater pipe system 4 connects thewater outlets pools water inlets water filter system 3. Water outputted from thewater outlet pool water pipe system 4 to the double-circulationwater filter system 3 for treatment, and well-treated water is then delivered by thewater pipe system 4 to thepool respective water inlets water pipe system 4, and adapted to control the flowing direction of water. - Referring to FIG. 4 again, the
pools - 1. When the
second pool 14 is set for warm water, thefirst pool 12 is set for cold water, the electromagnetic valves A, D and E are closed, and the electromagnetic valves B, C and F are opened. At this time, warm water passes out of thewater outlet 142 of thesecond pool 14 through thewater pipe system 4 into thefirst filter unit 30 where warm water is treated in proper order through thehair remover 38, thefilter tank 32, thechlorinator 34 and thechemical dispenser 36, and then passes out of thechemical dispenser 36 of thefirst filter unit 30 through the electromagnetic valve B to theheater 50 for heating, and then passes from theheater 50 through the electromagnetic valve C to thesecond pool 14 again. At the same time, cold water passes out of thewater outlet 122 of thefirst pool 12 through thewater pipe system 4 into thesecond filter unit 40 where cold water is treated in proper order through the hair remover 48, thefilter tank 42, thechlorinator 34 and thechemical dispenser 46, and then passes from thechemical dispenser 46 of thesecond filter unit 40 through the electromagnetic valve F to thefirst pool 12 again. - 2. When the
second pool 14 is set for cold water, thefirst pool 12 is set for warm water, the electromagnetic valves A, D and E are opened, and the electromagnetic valves B, C and F are closed. At this time, warm water passes out of thewater outlet 122 of thefirst pool 12 through thewater pipe system 4 into thesecond filter unit 40 where warm water is treated in proper order through the hair remover 48, thefilter tank 42, thechlorinator 44 and thechemical dispenser 46, and then passes out of thechemical dispenser 46 of thesecond filter unit 30 through the electromagnetic valve D to theheater 50 for heating, and then passes from theheater 50 through the electromagnetic valve E to thefirst pool 12 again. At the same time, cold water passes out of thewater outlet 142 of thesecond pool 14 through thewater pipe system 4 into thefirst filter unit 30 where cold water is treated in proper order through thehair remover 38, thefilter tank 32, thechlorinator 34 and thechemical dispenser 36, and then passes from thechemical dispenser 36 of thefirst filter unit 30 through the electromagnetic valve A to thesecond pool 14 again. - 3. When both
pools pools first pool 12 as well as w thesecond pool 14 is allowed to pass through theheater 50 for heating. - As indicated above, the warm/cold double-circulation water filter system and swimming pool arrangement of the present invention comprises a swimming pool, which is separated by a partition wall into two separated pools, a double-circulation water filter system, which has two filter units adapted to filter water from the two pools respectively, a heater adapted to heat water passing through, and a water pipe system with valve means adapted to control circulation of water from each pool through the double-circulation water filter system only, or selectively through the double-circulation water filter system and the heater.
- It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed.
