Definitions

  • This invention relates to a one-compartment filtration unit for a swimming pool.
  • the invention further relates to a wall element for a swimming pool containing the filtration unit of the invention.
  • the invention further relates to a swimming pool having a filtration unit according to the invention.
  • the invention also relates to a method of removing impurities floating in the water of a swimming pool or impurities floating on the water of a swimming pool, said method comprising the use of the filtration unit of the invention.
  • Filtration units for a swimming pool are known and are described e.g. in US 3,864,263; US 5,879,547; US 4,801,378; DE 295 01 221; US2002/0040869; WO00/47843.
  • filtration units containing a filter and a pump for circulating the pool water through the filtration unit.
  • Filtration units usually have at least two compartments, one compartment for the filtration element and a separate compartment for the pump, which allows to keep the electromotor of the pump separate from pool water for safety reasons.
  • Further equipment usually required for maintaining and servicing a swimming pool are heating devices, devices for disinfecting the pool water, devices for illuminating the pool for use in the dark etc. All this equipment is expensive and labour intensive to install, requires a lot of space, and is difficult to service.
  • the inventors have surprisingly found a filtration unit that combines the necessary water treatment and water afflux facilities in one unit.
  • the filtration unit of the invention is thus compact and requires little space.
  • the filtration unit can be essentially prefabricated and can easily be installed with a swimming pool, notably if it is integrated into a wall element. Integration into a wall element allows to have as many filtration units as required in a swimming pool and provides for simple installation of the filtration unit in a swimming pool. Further filtration units can be easily installed by replacing a wall element of a preexisting swimming pool by a wall element according to the invention that contains the one-compartment unit of the invention.
  • the filtration unit of the invention contains a device for measuring the water level in the swimming pool, allowing automatic refilling of water from an external source into the swimming pool.
  • the filtration unit of the invention contains a filtration unit, a pump, a device for automatic refilling of water, and all ducts required therefore in a single unit.
  • the filtration unit of the invention does not contain separate compartments for pool water filtration and water pumping. Instead, the filtration element and said pump(s) are present in one compartment.
  • the one-compartment filtration unit for a swimming pool comprises wall means for delimiting a filtration compartment in said filtration unit.
  • Said wall means may coincide with the walls of the wall element of the invention in which said filtration unit may be integrated.
  • Said wall means have various openings for allowing efflux and afflux of water out of or into, respectively, said swimming pool. These openings are preferably located on one side of said filtration unit, namely the front side of said filtration unit (cf. Fig. 1). Further openings may be present at other sides of said filtration unit, preferably the back side opposite of the front side, e.g. for connecting additional water treatment devices or for connecting an external water source.
  • the filtration unit of the invention has at least the following openings:
  • pool water having been received through said third opening may be conducted to a water treatment device like a heater or a disinfecting device through a duct.
  • Said water treatment device may be located inside said filtration compartment or outside said filtration compartment. If said water treatment device is located outside said filtration compartment, there will be a duct leading from said third opening through said filtration compartment to a further opening e.g. on the rear side of said filtration unit (cf. Fig. 3), where said water treatment device may be connected.
  • a water treatment device located outside of said filtration compartment will have an outlet and an outlet duct leading back into the swimming pool. This outlet duct may lead through said filtration compartment and may release treated water into the swimming pool through a fourth opening of said filtration unit. Therefore, the filtration unit preferably has a fourth opening in said wall means in this embodiment.
  • pool water entering said third opening may, optionally after having passed a water treatment device like a heater or a disinfecting device, enter the filtration compartment and mix in the filtration compartment with filtered water. Pool water having been received by said third opening may then be removed from the filtration compartment together with filtered water by said pump(s) through said second opening. Also in this case, the water received by said third opening will by-pass said filtration element.
  • a water treatment device like a heater or a disinfecting device
  • Said third opening is preferably occludable (e.g. via a valve) for regulating water influx into said third opening.
  • Said filtration compartment preferably contains a device for measuring the water level in the swimming pool, said device being capable of regulating a valve controlling water afflux into the swimming pool from an external source.
  • Said device may comprise a float that may be similar to a cistern float.
  • Said float may be capable of actuating a valve controlling water afflux to the swimming pool from said external source.
  • Said valve is preferably located in said filtration unit. Said water from said external source may be released into the swimming pool e.g. through said second opening, through said fourth opening, or through a further opening in the wall means of said filtration unit.
  • the filtration unit of the invention further contains, for submersion below the water level of the swimming pool, a filtration element for filtering pool water received through said first opening and one or more pumps for receiving filtered water and for pumping the filtered water into the swimming pool through said second opening.
  • Said filtration compartment inside said filtration unit may have a lid (H) with an opening serving as an inlet to said filtration element.
  • Said lid, said opening of said lid, and said filtration element may be arranged such that mixing of (unfiltered) pool water with filtered water in said filtration compartment are prevented, i.e. all pool water entering at said first opening has to pass said filtration element for reaching the pump inside said filtration compartment.
  • Said filtration element may comprise or consist of a filtration bag made of a fabric, said filtration bag being removably mountable at the opening of said lid.
  • Said filtration element may further have a pre-filter optionally equipped with water treatment chemicals.
  • Said pre-filter may have a wider mesh size than said filtration bag for filtering off coarse material like leaves from trees or grass.
  • the mesh size of the filtration bag is smaller and may be in the range of 1 to 500 ⁇ m, preferably, 4 to 100 ⁇ m, most preferably 5 to 50 ⁇ m.
  • the mesh size of the pre-filter may be between 100 and 5000 ⁇ m, preferably between 300 and 3000 ⁇ m, most preferably between 500 and 2000 ⁇ m.
  • the filtration unit of the invention may have a device capable of determining the pollution level of said filtration element and capable of switching off said pump if the pollution level of the filtration element is determined to be high.
  • Said device may be a relay system. If the pollution of the filtration element is high, the pump(s) may determine an increased resistance for pumping water. If the resistance exceeds a predetermined level, a signal may be generated leading to switching off of the pump(s). Further, a signal may be sent to service personnel indicating that the pre-filtter or the filtration bag have to be exchanged. Filtration bags or pre-filters are known in the art of the present invention.
  • the filtration compartment of the filtration unit contains one or more pumps for receiving filtered water and for pumping the filtered water into the swimming pool through said second opening.
  • Said pump(s) are preferably mounted below said filtration element e.g. at the bottom of said filtration compartment.
  • said pumps are driven by low-voltage electromotors, preferably by 12 V electromotors.
  • the electronmotor(s) of said pump(s) have a water-proof body. Typical pumping capacities are 5 to 50 m 3 /h.
  • the power of each pump may exceed 200 W. Due to the low voltage, no danger exists in case an electrical wire of said pump(s) comes in direct contact with water in the filtration compartment.
  • the capacity of the pump(s) may be changed by changing the voltage of the electrical power supplied to said pump(s).
  • the pumping capacity may be increased as desired by increasing the number of pumps. Multiple pumps may be operated in parallel or sequentially, whereby parallel mode is preferred. In this way, the pumping capacity may be adjusted to size of the swimming pool.
  • a duct connecting the outlet(s) of said pump(s) with said second opening. In the case of multiple pumps, said duct preferably receives the outlets from all pumps. Electrical wires leading to said pump(s) should not have connectors at locations that are submerged in water when the swimming pool is filled with water. Electrical high-voltage parts should be located at places that cannot be reached by water.
