Abstract

A device is provided for connecting pipe parts between two compartments of a filtration unit for water of a swimming pool. The filtration unit has a filtration compartment submerged in the water and equipped with at least one filtration means and a pumping compartment situated outside of the swimming pool and equipped with at least one suction and return pump. The compartments are connected by a common part that straddles the walls of the swimming pool. The filtration means and pump or pumps are connected in combination with suction and return pipe parts, which have one part situated in the filtration compartment and one part situated in the pumping compartment. At the common connecting part, watertight connecting members are positioned between the suction and return pipe conduit parts, whose thickness is less than the diameter of the various pipe parts.

Claims

1. Device for connecting pipe parts between two compartments of a filtration unit for water of a swimming pool, the filtration unit comprising a filtration compartment submerged in the water and equipped with at least one filtration means and a pumping compartment situated outside of the swimming pool and equipped with at least one suction and return pump, the compartments being connected by a common connecting part that straddles walls of the swimming pool, the at least one filtration means and at least one pump being connected in combination with suction pipe parts and return pipe parts, the suction pipe parts and the return pipe parts each comprising one conduit part situated in the filtration compartment and one conduit part situated in the pumping compartment, and further comprising, at the common connecting part, a watertight connecting module between the suction pipe parts and between the return pipe parts, a thickness of the connecting module being less than a diameter of the suction and return pipe parts.

2. Device according to claim 1, wherein the module has a thin flat cross section and defines, in section, two separate internal conduits, each conduit having members for watertight connection with flat-section connectors, the connectors being fixed to the conduit parts of the suction and return pipes positioned in the filtration and pumping compartments, and the module being arranged between the two compartments, at the common connecting part.

3. Device according to claim 2, wherein the connecting members of the module comprise flat-section adaptors in communication with the conduits.

4. Device according to claim 2, wherein the flat-section connectors are made integral, directly or by being connected, with round-section adaptors able to be connected by watertight engagement with the pipe parts.

5. Device according to claim 2, wherein the module comprises an independent add-on element fixed in a watertight manner to the common connecting part, between the two compartments.

6. Device according to claim 5, wherein the module has in section a profile able to fit in a complementary profile serving as a bearing cradle formed in a thickness of a separating plate belonging to the common connecting part.

7. Device according to claim 2, wherein the module and the two compartments are connected together by a common linking frame fitted with covers for closing each of said compartments.

8. Device according to claim 2, wherein the adaptors have a rectangular cross section.
