Description

[0001] The invention relates to a swimming pool according to the preamble of claim 1. State of the art

[0002] Swimming pools with height-adjustable pool floors are generally known.

[0003] A well-known swimming pool with a height-adjustable floor comprises an outer wall, as well as a first and a second swimming pool floor, whereby the second swimming pool floor can be moved along the outer wall.

[0004] In known swimming pools with height-adjustable pool floors, this pool floor has fountain nozzles, as in EP 3 933 144 B1, with the water supply provided via hoses that run through the outer wall of the pool and below the movable pool floor. Purpose and advantages of the invention

[0005] The object of the present invention is to provide a swimming pool with a height-adjustable pool floor, which allows for a more compact design.

[0006] This problem is solved by claim 1.

[0007] The dependent claims mention advantageous further developments of the invention.

[0008] For example, the second pool floor can be moved vertically along the outer wall, in particular up to above the water surface or up to the top edge of the outer wall. In this way, the second pool floor can be designed to be accessible without barriers.

[0009] According to the invention, a pump is provided on the second pool floor, which is designed to pump water through at least one nozzle opening into the swimming volume. This eliminates the need for an additional water line to the second pool floor or the pool wall, resulting in reduced resources and therefore lower costs. The pump(s) can move with the second pool floor as it moves. A supply line, in particular a hose, that runs from the outside through the first pool floor or through the outer wall is not required.

[0010] It is conceivable that a pump is present to deliver water through several nozzle openings. It is also conceivable that several pumps are present to deliver the water through multiple nozzle openings or through the respective nozzle openings.

[0011] Preferably, the pump is located within the second pool floor. This also allows for a compact design.

[0012] It is conceivable that the pump is located at least partially within the second pool floor. It is also conceivable that the pump is located partially below the pool floor.

[0013] Advantageously, at least one nozzle opening is designed so that the water pumped by the pump is directed into the swimming area. For example, the nozzle opening is designed so that the water is directed upwards or at least diagonally upwards out of the nozzle opening, creating a kind of fountain effect. Additional nozzle openings are also conceivable, which direct water downwards from the second pool floor into the subfloor volume; these, too, can be designed at an angle.

[0014] Of course, variations are also possible that use multiple pumps, each coupled to one or more nozzle openings through which water is pumped. This allows for a more customized and attractive fountain effect.

[0015] Preferably, the pump and the nozzle opening are designed such that water from the subfloor volume can be directed into the area above the second pool floor, particularly into the swimming area. It is also conceivable that water from the area above the swimming area is additionally pumped through the nozzle opening and directed back into the swimming area. This can be implemented, for example, depending on the position of the second pool floor. Advantageously, this also enables water circulation within the pool, particularly from the subfloor volume to the swimming area and vice versa.

[0016] Preferably, at least one nozzle opening is continuously connected to an inlet opening on the underside of the second pool floor. For example, at least one nozzle opening is continuously connected to an opening on the other side of the second pool floor. In this way, water can be pumped through the inlet opening from the lower area, the subfloor volume, through the nozzle opening into the area above the second pool floor. The water can then flow automatically from the pool volume to the subfloor volume and back again.

[0017] For example, the inlet opening is extended, for example by a piece of hose that extends from the respective pump and / or from the underside of the second swimming pool floor into the subfloor volume.

[0018] Preferably, the second pool floor is arranged above the first pool floor.

[0019] Advantageously, the first swimming pool floor is designed to be static and / or non-movable.

[0020] Preferably, the swimming pool has a water supply line for feeding fresh and / or treated water into the interior. For example, the fresh water can be treated, particularly purified. It is conceivable that the fresh water is fed into the subfloor volume via the water supply line. Alternatively, depending on the position of the second pool floor, the fresh water can be fed into the swimming area via the water supply line, e.g., through the outer wall or through the first pool floor. However, a direct pipe connection between the fresh or treated water supply line and the pump is not necessary. Character description

[0021] An exemplary embodiment is explained in more detail with reference to the schematic drawings below, including further details and advantages: Fig. Figure 1 schematically shows a cross-section of a swimming pool according to the invention. Fig. Figure 2 schematically shows a cross-section of another variant of the swimming pool 1 according to the invention.

[0022] At the in Fig. In the example shown, the surrounding outer wall 4 and the first pool floor 2 define an internal volume 5 for holding the water. The height-adjustable second pool floor 3, together with the outer wall 4, defines a swimming volume 6 above the second pool floor 3. The first pool floor 2, the outer wall 4, and the second pool floor 3 define a subfloor volume 7.

[0023] The diagram shows one variant in which three pumps 9 pump water from the bottom volume 7 through a nozzle opening 8 into the floating volume. Variants with more or fewer than three pumps 9 are of course also conceivable.

[0024] Also shown is a water supply line 10 for the supply of fresh / treated water.

[0025] Fig. Figure 2 shows a variant of the swimming pool 1, in which a pump 9 delivers water through several nozzle openings 8 into the swimming volume. Variants with one pump 9 and more or fewer than three nozzle openings 8 are also conceivable.

[0026] Of course, variants are also possible in which several pumps are used, which are coupled with different numbers of nozzle openings through which water is to be conveyed.
