Definitions

  • This invention relates to an improved swimming pool cleaning device which is simple in construction and which will automatically move around the entire pool area without entrap ment against pool edges or in corners.
  • the most prevalent type of device utilizes a floating head with one or more fixed position nozzles around its perimeter to drive it across the water surface by the force of the water ejected from said nozzle(s).
  • One of these contains a complicated gear train and internal valve set-up driven by a water turbine so that water is ejected from two or more nozzles in rotation.
  • Another device gives up on solving the programmed floating head problem, and consists of a head with four flexible tubes attached which sinks to the bottom of the pool and stays there until removed, with its attached tubes snaking around stirring up the debris. This head does not move at all, resulting in spotty and inadequate coverage for cleaning.
  • the swimming pool cleaning device of this invention in a representative embodiment, comprises a floating head which is placed on the pool surface, which is supplied with water pressure via a floating flexible hose, and beneath which are several attachments, each receiving a portion of the available water pressure supply.
  • the attachments are: at least one flexible hose equipped with a nozzle at its bottom end; and a swivel impeller and rudder assembly so constructed that it propels and guides the head around the pool in a random manner.
  • the actual cleaning of the pool sides and bottom is accomplished by the scouring action of the water ejected from the noules at the bottom ends of the dangling flexible tubes as the head moves around the pool.
  • the scouring action stirs up the dirt and debris, which becomes temporarily suspended in the water long enough to be removed by the pools normal filtering system.
  • the time for complete pool cleaning varies with the amount and types of soil to be removed, the capacity of the filtering system and the available water pressure and volume which can be used to operate the cleaner. In normal circumstances, this time will average between 4 and 10 hours.
  • FIG. 1 is a top plan view of a pool showing the pool cleaning device of the invention in solid lines in one position in the pool and in broken lines in another position.
  • FIG. 2 is an enlarged top view of the floating head of the pool cleaning device.
  • FIG. 3 is a sectional view taken on the lines 3--3 of FIG. 2.
  • FIG. 4 is an enlarged sectional view taken on the lines 44 of FIG. 3.
  • FIG. 5 is a fragmentary view showing a floating supply hose assembly.
  • the pool cleaning device comprises floating head 10 which is adapted to move about the surface of pool 12.
  • the head 10 is conveniently constructed of foam plastic, but can be made of any material which will float and can take any of the variety of shapes and sizes. In the embodiment shown it is shaped like a life buoy but could be of solid, oval, rectangular or other shape.
  • a water distributing assembly 14 comprising pipes 16, 18, 20 and 22, tees 24 and 26 elbows 28 and 30 and union 32.
  • the union 32 is connected to a short piece of pipe 34 which extends from the head 10 and terminates in coupling 36 to which flexible supply line 38 is attached.
  • the supply line 38 is in turn attached at its other end to a source of water under pressure 40, which may be an outlet from the pool filter system.
  • the pipes and fittings mounted on the floating head 10 are conveniently made from rigid plastic to save weight and avoid corrosion problems.
  • a float 42 is attached to connecting pipe 34 to add buoyancy to the system.
  • the supply lines 38 is one which will float. This can be accomplished by several means including the attachment of floats at intervals.
  • a preferred embodiment is shown in FIG. 5 wherein an outer floatable hose 44 of foamed plastic material such as a floating pool vacuum hose encompasses a flexible inner hose 46 which carries the water under pressure. Vacuum hose of 1 k inch diameter in combination with three-fourths inch vinyl tubing is suitable for this purpose.
  • the elbows 28 and 30 are each equipped with a short nipple 48 extending downwardly through an opening 50 in the floating head 10.
  • a union 52 secures the assembly in position.
  • a short length of pipe 54 extends downwardly from the union 52.
  • the floating head may be l820 inches in diameter with the elbows 28 and 30 approximately 16 inches apart on centers.
  • the pipes 54 may extend approximately 8 inches below the floating head 10 before their attachment to the cleaning tubes.
  • Two flexible tubes 56 and 58 are attached to the respective pipes 54.
  • Each tube is equipped with a nozzle 60 of the flat fan spray pattern type with a fixed size orifice at one end of the tube.
  • Flat fan spray noules 60 are eminently suitable for tubing that is manufactured in coils, and has a coil set. This natural coil set causes either one side or the other of the tubing to lie on the bottom.
  • the nozzle is set to spray perpendicularly to the coil set of the tubing, so that half the ejected water from the nozzle must impinge against the pool bottom at all times when the nozzle is against the bottom.
  • the flexible cleaning tubes 56 and 58 are preferably of different lengths.
  • one of the tubes may be 15 feet long, causing it to range far away from the floating head and to reach the deepest parts of the pool.
  • the other tube may be feet long, and touches the bottom in the shallow end only. However, it serves to keep sediment suspended at all times, and cleans the side walls of the pool when it is brought within reach by the head.
  • a swivel impeller and drive assembly generally designated at 62. As best shown in FIGS. 3 and 4, this comprises a downwardly extending pipe 64 carrying a ho]- low swivel joint 66 from which depends another short length of pipe 68 closed by cap 70. All of these parts may be conveniently made of plastic.
  • a metal impeller tube 72 communicates with the pipe 68 through the cap 70.
  • On the other side of cap 70 a flat plastic or metal rudder 74 is secured by means of cap screw 76.
  • the tee 24 and its depending swivel drive assembly 62 may be offset from the geometrical center of the floating head so as to facilitate irregular directional movement of the device around the pool.
  • the swivel drive assembly 62 is the heart and brain of the cleaning device of this invention since it impels and guides the floating head 10 around the pool surface. Its principle is new but simple.
  • the lower part of the assembly rotates freely around the hollow supporting pipe 64.
  • the assembly has only two essential parts besides the swivel itself; an impeller tube 72 bent at an angle of e.g., 3-l0 from a radial line drawn horizontally from the swivel center which causes counterclockwise swivel rotation when water is ejected through the tube 72 under pressure; and the flat metal or plastic rudder 74 fastened to the same part of the swivel as the impeller tube, set vertically and projecting to one side of swivel center opposite to the angle bend of the tube 72.
  • This rudder 74 has little effeet on the swivel action when the head 10 is stationary, thus allowing the bent tube 72 to cause CCW swiveling action, but when the head 10 is moving across the water, the rudder 74 tends to cause clockwise swivel actionopposing the action of the tube 72.
  • the drive jet will always cause the assembly to swivel when the head 10 is stalled, but may not swivel at all or swivel in the opposite direction when the head 10 is moving, depending on the speed of movement, since the pool water exerts more force against the rudder the faster it is propelled through the water. The result is random travel of the head but programmed to prevent entrapment.
  • FIG. 1 The manner in which the impeller and rudder assembly will swivel around upon entrapment of the head 10 is illustrated at the lower right hand corner of FIG. 1.
  • the device shown in broken lines has been driven into the corner of the pool.
  • the impeller action of the tube 72 has caused the drive assembly to rotate counterclockwise from the angular position of the device shown in solid lines at the center of the pool.
  • the action of the impeller will new drive the device out of the comer to again randomly proceed across the pool surface.
  • the invention embodies a new and unique method of propelling floating cleaner head around the pool surface via a swiveling drive impeller which swivels when the head is stopped for any reason until it reaches a position to drive the head away from the trapped position, no matter what caused it or where it is on the pool surface.
  • the swivel does not rotate.
  • the impeller and swivel tend to rotate in a direction opposite to that evidenced when the head is not moving.
  • the novel pool cleaning device travels completely around the perimeter of any shape pool, cannot be trapped by any corner or obstruction, and makes occasional side trips out into the middle of the pool, sometimes crossing over from side to side or end to end, sometimes lingering in an area performing a roughly oval oscillating movement, finally returning to its travel around the pool perimeter.
  • the head will traverse all the area of the pool surface several times. It may be placed in the pool in the evening and allowed to run all night. Results have been perfect, in that it never stalls or becomes trapped, it covers the entire surface and bottom areas and cleans the pool bottom and sides to the point where no debris is visible the following morning. Manual vacuuming is no longer required.
  • a swimming pool cleaning device comprising a movable floating head carrying at least one cleaner hose, a water jet impeller and means for supplying water to said cleaner hose and impeller, the improvement comprising a swivel carrying said impeller and also carrying a rudder, the impeller being arranged and directed to cause rotation of the swivel and the rudder tending to counteract such rotation whereby said impeller and rudder cause the floating head to move in an irregular pattern around the pool and to move away from pool walls and comers it may engage.
  • the impeller comprises a pipe extending horizontally from the swivel at an angle to the rudder and wherein said pipe is bent at a slight angle away from the direction in which the rudder extends.
  • the device of claim 1 including a floatable flexible water supply hose for supplying water from a source at pool-side to the movable floating head for distribution to the cleaner hoses and water jet impeller.
  • said floatable water supply hose comprises an outer hose of flexible foamed plastic and a flexible water carrying hose within said inner hose.
  • At least one cleaner hose has a coil set and the terminal end of said cleaner hose is provided with a nozzle directed perpendicular to the coil set so as to direct cleaning water against the pool bottom.
  • a swimming pool cleaning device comprising, a floating head adapted to move upon the surface of the pool; a pipe extending downwardly from said floating head; a swivel joint in said pipe; water distributing means carried by said floating head, said water distributing means including first connecting means for a flexible water supply hose, second connecting means for at least one flexible cleaner hose and means connecting said first connecting means with the second connectdownwardly from said floating head to a position below said impeller and rudder to prevent them from engaging shallow pool obstructions.
  • the means extending downwardly from the floating head comprise short pipes to which the flexible cleaner hoses are adapted to be attached, said pipes comprising part of said second connecting means.
