Abstract: A pool cleaner for cleaning a pool includes a housing with an upper surface and downwardly projecting sidewalls extending from the upper surface for defining a front, a rear, a first and a second side of the housing. A first pair of wheels includes a first wheel being pivotally mounted relative to the first side of the housing and a second wheel being pivotally mounted relative to the second side of the housing. A tie rod is operatively mounted relative to the first wheel and the second wheel. A second pair of wheels is mounted on the rear end of the housing. As the pool cleaner traverses a pool surface and the first or second wheel is moved to be at a predetermined angular relationship relative to the housing, the tie rod ensures that the first and second wheels are at substantially the same angular relationship relative to the housing.

Abstract: The present invention relates to swimming pools and other pools of standing water, and in particular to a dispensing unit that distributes a chemical solution that reduces evaporation and heat loss by forming a film or monomolecular layer over the surface or substantial surface area of the swimming pool or water pond.

Abstract: The present invention relates to a sealed box apparatus for a pool cleaning machine wherein the sealed box is installed inside the body of the pool cleaning machine. The box contains and seals electronic devices for the cleaning machine. At least one waterproofed tube is provided for inputting and outputting wires for connecting the electronic devices sealed inside the box with peripherals. A transparent portion is installed on one side of the box. A humidity display is installed inside the box, and corresponds to the position of the transparent portion. The sealed box provides an excellent airproof seal for protecting the inside electronic circuits from being waterlogged, and to provide excellent heat elimination, while leakage into the sealed box may be conveniently monitored in real-time.

Abstract: A self-propelled swimming pool cleaner which randomly covers the bottom of the pool. Water pumped from the bottom of the unit filters dirt carried thereby, then uses the pumped water to propel the device either forward or backward. A pivoted front axle causes the path of the unit to vary when changing from forward to backward so that the unit randomly covers the entire pool bottom. Spring loaded doors may be provided to allow water to exit when the unit is lifted out of the pool. A sealed motor unit has a metal portion to transfer heat from the motor.

Abstract: An underwater light for use with soft-sided aboveground pools includes a watertight light fixture utilizing a low voltage (12V) current for use in underwater illumination of a swimming pool. A mounting assembly is provided that is attached to the light fixture for allowing attachment of the assembly to a support frame of a soft-sided aboveground pool. A transformer is provided for containing controls for an automatic timer and for providing variable intensity lighting to the system.

Abstract: An electrolytic cell combined into a unitary structure with a liquid circulation fitting, which purifies water by electrode plates inside the cell when an aqueous solution is present. The unitary structure replaces the existing water return fitting. This integrated structure is well suited for use in pools, tubs, spas, fountains or similar large liquid containers. The production of halogen inside the structure is not required to coincide with the cycle of the existing pool filtration system. Rather, the electrodes receive a continuous supply of low level power and the halogen produced inside the structure is disbursed back into the body of water through the fitting using an integrated, dedicated circulation pump, special channels in the surface and a check valve to insure one directional flow from the pool pump and natural convection. Using fresh water drawn from the vessel, halogen is then disbursed back into the vessel with the water at a location different from where the fresh water was drawn.
