SWIMMING POOL Russian patent published in 2012 - IPC E04H4/16 

FIELD: construction.

SUBSTANCE: swimming pool comprises a reservoir from boards solid in side length with an inner hydraulic insulating coating from a PVC film. An overflow chute is installed along its perimetre, used as a water self-treatment system. The chute includes a bottom joined with reservoir walls, a rear wall, a filtering material laid onto the bottom of the overflow chute, where a floating overflow mat is laid with an edge hanging below the bottom of the overflow chute. The filtering material is installed at least in two opposite corner zones of the overflow chute, has an inclined shelf inclined towards the poll reservoir side and is laid onto the bottom with a gap, forming a drain channel, closed at the ends with edges adjacent to its bottom. The overflow mat arranged on the filtering material is pressed to its inclined shelf with an inclined shelf installed above the overflow chute of the grid. The edge hanging below the bottom of the overflow chute is fixed along the upper edge of pool reservoir walls with a dotted seam in areas to locate the filtering material and with a solid seam in areas free from the filtering material. Drain channels at one side are joined with a pipeline with a suction nozzle of an electric pump, the injection nozzle of which is connected to a pipeline equipped with a double-way valve, or directly with the pool reservoir, or via a water disinfection device, for instance, a system of its ultraviolet radiation. At the other side drain channels are joined with a pipeline with a suction nozzle of a circulating electric pump, the injection nozzle of which is connected to a pipeline equipped with a double-way valve, or directly with the pool reservoir, or via a water heating device, for instance, a heat exchanger, operating from a gas water-heating unit (WHU).

EFFECT: invention makes it possible to provide for rational use of a filtering material and required extent of water treatment depending on intensity of pool usage.
