Abstract

Power supplies for pool and spa equipment are disclosed. In one embodiment, the power supply includes a buoyant housing, a peripheral float, at least one solar cell positioned on the buoyant housing for collecting sunlight and converting same to electrical energy, and a power cable for interconnecting the power supply and pool/spa equipment. In other embodiments, first and second inductive power couplings are provided for powering pool and spa equipment. The power couplings can also be installed using existing plumbing features of the pool or spa.

Claims

1. A power supply for powering pool or spa equipment, comprising:

a power supply unit external to a pool or a spa;

a first inductive power coupling including an inductor circuit, said first inductive power coupling in electrical communication with the power supply unit and at least partially embedded in the pool or spa;

a second inductive power coupling including an inductor circuit, said second inductive power coupling received by said first inductive power coupling in the pool or spa, wherein the inductor circuit of the first power coupling inductively transmits power from the power supply to the inductor circuit of the second inductive power coupling for powering a device in a pool or spa connected to the second inductive power coupling; and

a cable connected at a first end to the device and at a second end to the second inductive power coupling such that the second inductive power coupling is detached from the device, the cable delivering electrical power to the device and permitting movement of the device relative to said first and second inductive power couplings while said second inductive power coupling is received by said first inductive power coupling.

2. The power supply of claim 1, wherein the first inductive power coupling includes a housing defining a cavity for receiving the second inductive power coupling.

3. The power supply of claim 2, wherein the second inductive power coupling is configured to be inserted into the housing of the first inductive power coupling.

4. The power supply of claim 1, wherein the first and second inductive power couplings are flat plates, each including means for releasably securing the inductive power couplings to each other.

5. The power supply of claim 4, wherein the means for releasably securing the inductive power couplings to each other are magnetic.

6. The power supply of claim 1, wherein the device is a pool cleaning device.

7. The power supply of claim 6, wherein the pool cleaning device includes a rechargeable battery rechargeable by the power supply.

8. The power supply of claim 1, wherein the power supply unit comprises one or more of an A/C power supply, a battery, or a solar array.

9. The power supply of claim 1, wherein the first and second inductive power couplings operate as a transformer for changing one voltage level to a different voltage level.

10. A power supply for powering pool or spa equipment, comprising:

a power supply unit external to a pool or spa;

a first inductive power coupling including an inductor circuit, said first inductive power coupling in electrical communication with the power supply unit and positionable in an existing plumbing fixture of a pool or a spa;

a second inductive power coupling including an inductor circuit, said second inductive power coupling positionable proximate to said first inductive power coupling, wherein the inductor circuit of the first power coupling inductively transmits power from the power supply to the inductor circuit of the second inductive power coupling for powering a device in a pool or spa connected to the second inductive power coupling and

a cable connected at a first end to the device and at a second end to the second inductive power coupling such that the second inductive power coupling is external to the device, the cable delivering electrical power to the device and permitting movement of the device relative to said first and second inductive power couplings while said second inductive power coupling is received by said first inductive power coupling.

11. The power supply of claim 10, wherein the existing plumbing fixture is a suction port.

12. The power supply of claim 11, wherein the second inductive power coupling is sized and shaped to be inserted into the suction port.

13. The power supply of claim 10, wherein the first inductive power coupling includes a housing defining a cavity for receiving the second inductive power coupling.

14. The power supply of claim 13, wherein the second inductive power coupling is configured to be inserted into the housing of the first inductive power coupling.

15. The power supply of claim 10, wherein the first and second inductive power couplings are flat plates, each including means for releasably securing the inductive power couplings to each other.

16. The power supply of claim 15, wherein the means for releasably securing the inductive power couplings to each other are magnetic.

17. The power supply of claim 10, wherein the device is a pool cleaning device.
