초록 ▼

The disclosure relates to a method and apparatus for swimming pool cleaning incorporating intermittent pop-up jet rotated nozzles; the nozzles being adapted to intermittently rotate and project cleaning jets of water adjacent said inner surface. The nozzles each have eccentrically positioned tangential water outlets forming jet outlet passages; the nozzles are vertically reciprocal and are rotatably mounted in housings having stop means such that when they are hydraulically energized by water under pressure in the housings, the nozzles emerge from the upper ends of the housings and cause jet reaction rotation thereof during upward movement which is arrested by the stop means in the housing. The housing includes a bore with clearance around the nozzle so as to provide a water bearing around the nozzle during its upward and rotative movement. A plurality of such nozzles are disposed in a swimming pool and the nozzles are successively and sequentially hydraulically energized by water under pressure from a sequencing valve which receives water from a water pump which in turn receives water from the pool.

A system for cleaning the inner surfaces of a swimming pool, said pool having means for introducing water under pressure into said pool, means for withdrawing water containing suspended deleterious matter from said pool and conducting said water to a filter where said suspended deleterious matter is separated from said water, and means for returning said filtered water from said filter to said pool, said system comprising a water delivery assembly located upon the inner surface of said swimming pool, said assembly comprising: (a) a housing in fluid communication with a source of water under pressure, said housing having an outer open end communicating with the interior of said swimming pool; (b) a rotatable water delivery head formed as a single moving part having an upper end and at least one water aperture therein to project a pressurized stream of water in adjacent parallel and scrubbing relation to the inner surface of said pool, said delivery head being mounted in said housing and adapted for reciprocal motion therewithin to an extended operative position and a retracted inoperative position, said delivery head also adapted for limited random rotation only when positioned between said extended operative position and said retracted inoperative position; (c) said water delivery head responsive to the application of pressurized water to said housing for extending non-rotational to said extended operative position; said head also responsive to the removal of pressure from the water in said housing for retraction to said retracted inoperative position; (d) means responsive to the application of pressurized water to said housing for rotating said delivery head a randon angular distance during movement between its retracted inoperative position and extended operative position; and (e) means for stopping rotation of said delivery head when it is in its extended operative position to permit the projection therefrom of a pressurized stream of water, in a random direction, of sufficient velocity to clean the inner surface of said pool, said means for stopping said rotation comprising a radially extending collar on said delivery head, and an annular ledge in said housing, friction means on said collar and ledge coming into contact with each other when said head is in said extended position to stop rotation of said rotatable water delivery head.
