Hydraulic swimming pool cleaners with electricity generators

摘要

Generation of electricity on-board, principally, certain hydraulic pool cleaners is described. Magnets may be caused to move within coils by (normal) cooperative actions of diaphragm-type valves and external pumps, thus generating electricity without changing the operational principles of the cleaners. The generated electricity may be used to power electrical devices either on-board the cleaners or elsewhere.

1. A method of generating electricity by an automatic swimming pool cleaner having a body including (i) an inlet for receiving water and (ii) an outlet, the method comprising:
a. placing the cleaner in fluid communication with a pump external to the cleaner; and b. operating the pump so as to cause water to flow through a valve positioned in a first water flow path between the inlet and the outlet of the body, cooperation of the valve and pump resulting in oscillatory movement of a magnet positioned in a second water flow path of the body to generate electricity in a coil that is stationary relative to the body.
