Benefits of technology

The present invention causes a rotational flow in a device that is believed to help direct the force of the vortex above the topmost portion of the funnel portion to the surface of the pool. This beneficial and useful effect is achieved when the topmost portion of the funnel portion is disposed below the water surface by a distance preferably ranging from one to four inches.

Problems solved by technology

From the foregoing, it is seen that it is a problem in the art to provide a device meeting the above requirements.

working embodiment

[0045]In a working embodiment, the dimensions of the parts are preferably as follows. The pipe 170 can be composed of standard PVC pipe with a 2 inch diameter, and the pipe 180 a similar pipe but with a 1.25 inch diameter. The pipe 190 is preferably similar to the pipe 170, or can be larger or smaller, for example 1.5 inches, as long as it can supply a sufficient water flow. The diameter of the inner cup-shaped portion 130 is three inches in the working embodiment, while the diameter of the funnel portion 110 is nine inches in the working embodiment. The conduits 162 and 164 in the working embodiment are formed by flexible plastic tubing having a one-quarter inch diameter. The length of the funnel portion 110 is ten inches in the working embodiment, and the inner, tapering funnel-shaped portion 120 begins to taper at a point six inches below the uppermost edge of the funnel portion 110 as viewed in FIG. 2. The depth (length) of the inner cup-shaped portion 130 is four inches.

Abstract

A whirlpool skimming device removes surface debris from a pool by creating a whirlpool having an upper bound at the surface of the pool. The uppermost portion of the whirlpool is free standing and is not bounded by the device. The device includes an outer cup-shaped portion and an inner cup-shaped portion coaxially disposed therein. An opening is disposed in the bottom of the inner cup-shaped portion which communicates with a source of suction which is preferably a Venturi tube feeding the outlet water to a filter bag. There is a first nozzle supplying water at an upper, inner edge of the inner cup-shaped portion at a slightly downward angle in a first direction, and there is a second nozzle supplying water at a lower, outer edge of the inner cup-shaped portion and mounted on an opposite side of the inner cup-shaped portion. The device causes coaxial rotational flow patterns relative to the inner cup-shaped portion, in which the outer rotational flow takes an upwardly spiral path outside the inner cup-shaped portion, and the inner rotational flow takes a downwardly spiral path inside the inner cup-shaped portion of the device.
