Abstract

A recirculating pump system is connected to either skimmers, or a catch basin for a vanishing edge of a swimming pool, to supply water to the suction inlet of the pump system. A water distribution valve operated by an electric control system distributes water from the outlet side of the recirculating pump system to pool cleaning heads normally in accordance with a preprogrammed timed sequence. As part of each programmed cycle of operation of the water distribution valve, water is supplied to one or more pool return jets located on a side opposite the skimmer or catch basin. The return jets create moving surface currents on the water to sweep debris floating on or near the water surface to the skimmer or catch basin. An electric wind speed detector located in the vicinity of the pool and coupled to the electric control system causes the control system to override the programmed sequence in response to wind exceeding a pre-established threshold to operate the pump system to supply water to the pool return jets.

Claims

1. A cleaning system for a swimming pool having first and second opposite ends including in combination:

a recirculating pump system having a suction water inlet and at least one water outlet;

a device at the first end of the pool for supplying water from substantially the surface of the water in the pool to the suction water inlet of the recirculating pump system;

at least one pool return outlet at the second end of the pool connected to the at least one water outlet of the recirculating pump system and located to create movement of water along the surface of the water in the pool from the second end of the pool toward the device at the first end of the pool for supplying water from substantially the surface of the water in the pool to the suction water inlet of the pump system;

an electric wind speed indicator located to sense air movement in the vicinity of the swimming pool and coupled with the recirculating pump system for causing operation of the recirculating pump system to recirculate water from the suction water inlet thereof to the at least one water outlet thereof in response to air movement above a predetermined threshold.

2. The cleaning system according to claim 1 wherein the recirculating pump system operates to recirculate water from the suction inlet thereof to the at least one water outlet thereof for a predetermined time interval following the presence of air movement above the predetermined threshold.

3. The cleaning system according to claim 2 further including a water delivery device located in the floor or wall of the pool, wherein recirculating pump system includes a plurality of water outlets and a water distribution valve for alternately supplying water through selected ones of the water outlets to the water delivery device and the at least one pool return outlet.

4. The cleaning system according to claim 3 wherein the at least one pool return outlet is a plurality of pool return outlets located at spaced intervals from one another near the surface of the water at the second end of the pool.

5. The cleaning system according to claim 4 wherein the control system has an operating program to operate the water distribution valve to supply water to the water delivery device for a first predetermined period of time, and to supply water to said at least one pool return outlet for a second predetermined period of time;

and wherein the device responsive to air movement above the predetermined threshold causes the control system to override the operating program.

6. The cleaning system according to claim 5 wherein the device for supplying water from substantially the surface of the pool to the suction inlet of the recirculating pump system comprises a catch basin of a vanishing edge pool.

7. The cleaning system according to claim 5 wherein the device for supplying water from substantially the surface of the pool to the inlet of the recirculating pump system is a pool skimmer.

8. The cleaning system according to claim 2 further including a water delivery device located in the floor or wall of the pool, wherein recirculating pump system includes a plurality of water outlets and a water distribution valve for alternately supplying water through selected ones of the water outlets to the water delivery device and the at least one pool return outlet.

9. The cleaning system according to claim 8 wherein the at least one pool return outlet is a plurality of pool return outlets located at spaced intervals from one another near the surface of the water at the second end of the pool.

10. The cleaning system according to claim 9 wherein the control system has an operating program to operate the water distribution valve to supply water to the water delivery device for a first predetermined period of time, and to supply water to said at least one pool return outlet for a second predetermined period of time;

and wherein the device responsive to air movement above the predetermined threshold causes the control system to override the operating program.

11. The cleaning system according to claim 1 wherein the device for supplying water from substantially the surface of the pool to the inlet of the recirculating pump system is a pool skimmer.

12. The cleaning system according to claim 1 wherein the device for supplying water from substantially the surface of the pool to the suction inlet of the recirculating pump system comprises a catch basin of a vanishing edge pool.

13. The cleaning system according to claim 1 wherein the at least one pool return outlet is a plurality of pool return outlets located at spaced intervals from one another near the surface of the water at the second end of the pool.
