Power supplies for pool and spa equipment
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.
1 . An inductive power coupling system for powering pool or spa equipment, comprising:
a first inductive power coupling installable at a pool or a spa, the first inductive power coupling configured to receive electrical power from a power supply; and
a second inductive power coupling inductively receiving power from the first inductive power coupling and transmitting the power to a pool or spa device connected to and remote from the second inductive power coupling.
2 . The system of claim 1 , wherein the first inductive power coupling includes a housing defining a cavity for receiving the second inductive power coupling.
3 . The system 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 system 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 system of claim 4 , wherein the means for releasably securing the inductive power couplings to each other are magnetic.
6 . The system of claim 1 , wherein the device is a pool cleaning device.
7 . The system of claim 6 , wherein the pool cleaning device includes a rechargeable battery.
8 . The system of claim 1 , wherein the power supply comprises one or more of an A/C power supply, a battery, or a solar array.
9 . The system 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 . The system of claim 1 , wherein the first inductive power coupling is at least partially embedded in the pool or spa.
11 . The system of claim 1 , wherein the first inductive power coupling is positionable within an existing plumbing fixture of the pool or spa.
12 . The system of claim 1 , wherein the first inductive power coupling is positionable within a pipe embedded in a wall of the pool or spa.
13 . The system of claim 12 , wherein the pipe includes a suction port.
14 . The system of claim 13 , wherein the second inductive power coupling is sized and shaped to be inserted into the suction port.
