Definitions

• the present invention relates to the field of pools, installed above ground or buried, and in particular pools with moving bottom.
• the invention relates more particularly to a swimming pool with moving bottom and overflow.
• overflow swimming pools which are appreciated for their aesthetics and which are characterized by one or more sides of the pool provided overflowing under the action of a pump system: in such a pool the water level is thus substantially constant regardless of bathing conditions (such as the number of bathers, the volume of water overflowing) or external conditions such as bad weather.
• Such swimming pools thus require, and with respect to a non-overflowing pool, a water recirculation circuit that includes one or more secondary tanks (distinct from the overflow bathing volume).
• This or these secondary tanks have the function of collecting the overflow water, and serve as a buffer when the volume of water in the pool varies, for example due to the presence of bather in the swimming pool volume in the pool. overflow, or due to extra water such as rainwater.
• the recirculation circuit ensures a flow of water that keeps the water level of the pool constant, continuously overflowing.
• overflow pools have the first disadvantage of requiring a large building space, not only because of the main construction, namely the tank defining the overflow bath volume, but also in because of secondary tanks, buffer function that occupy additional space to this construction.
• overflow pools Due to the continuous overflow of the swimming pool, which favors heat exchange and evaporation, overflow pools still have the major disadvantage of cooling the pool water, which often requires the addition of a heating system. for example heat pump and increases operating costs.
• swimming pools with a movable floor are also known, for example to improve the safety of young children by adjusting the depth of the basin.
• the mobile platform still allows, when the pool is not used, to be able to use the surface of the platform as a floor.
• the movable bottom is in the form of a platform that can pass from a low, submerged position, in which the movable bottom constitutes the bottom of the pool, to a high position, in the open air, in which the moving floor forms a floor.
• the platform comprises a platform intended to be trampled and an onboard ballast intended to be filled with water or air according to the position one wishes to give to the mobile background.
• an onboard ballast intended to be filled with water or air according to the position one wishes to give to the mobile background.
• By changing the buoyancy of the platform it is possible to operate the platform on descent or ascent.
• Other modes of actuation of the platform are known from other prior art, such as for example cylinders, or cable systems and pulleys.
• the platform is permeable, in particular perforated, so as to let the water circulate through the platform during the climb and lowering.
• such an embodiment does not thermally isolate the pool, or even constitute a screen against evaporation, when the platform is in the high position. This has the consequence, on the one hand, of increasing the energy consumption for heating and, where applicable, the energy imparted to dehumidify the environment of the building in which the swimming pool is located.
• Document FR 1350562 of the present applicant discloses a swimming pool with a moving bottom which comprises a water circulation conduit, peripheral and external to the bathing volume.
• This peripheral circuit comprises an upper mouth and a lower mouth communicating with the bathing volume.
• this circuit allows the flow of water from the top to the bottom of the platform, the water entering through the upper mouth in the circuit, emerging through the lower mouth, under the action of thrust of the platform. Conversely, and during descent movement, the circuit allows the flow of water from below to the top of the platform, the water entering through the lower mouth in the circuit, emerging through the upper mouth, under the pushing action of the platform.
• Such a circuit advantageously makes it possible to use a platform with an impermeable wall, which makes it possible in particular to obtain good thermal insulation performance when the platform is in the high position, above the water, while limiting the dimension of the peripheral clearance between the platform and the side walls of the bathing volume, which is at the origin of a risk of pinching.
• the mobile platform in the high position, extends the floor area around the pool, providing a perfectly flat floor, advantageously without discontinuity between the surface of the mobile platform while in high position and the surface of the peripheral floor to the pool.
• a platform pool with a moving bottom according to the design of document FR 1350562 is however not compatible with a design of the overflow pool.
