Automatic pool cleaner

An automatic pool cleaner is provided of the type for random travel over submerged floor and side wall surfaces of a swimming pool or the like to dislodge and collect debris. The pool cleaner includes an electric-powered traction drive system for rotatably driving cleaner wheels, and an electric-powered water management system including a water supply pump and related manifold unit for venturi-vacuuming and collection of settled debris within a porous filter bag. A directional control system including an on-board compass monitors turning movements of the pool cleaner during normal random travel operation, and functions to regulate the traction drive system in a manner to prevent, e.g., excess twisting of a conduit such as a power cable tethered to the pool cleaner.

Machine for anticipatory sensing and intervention to avoid swimmer entrapment

A machine for anticipatory sensing and intervention to avoid swimmer entrapment, with an active pre-entrapment sensor (e.g. ultrasonic) that assesses the relative hazard based on swimmer proximity to the drain cover. An Ultrasonic Transducer launches waves into the suction piping and / or drain system, and to receive echoes from the drain cover, swimmer limbs, hair or body, and the water surface parellel to the drain cover. A Transmitter / Pulser electrically energizes the ultrasonic transducer to launch waves into the suction piping and / or drain system, A Receiver / Processor detects the echoes electrical signals from the the ultrasonic transducer and to receive echoes from objects of interest beyond the pool drain. A Logic and Control element converts the detected signals into reliable information regarding a swimmer safety / hazard status. An Output provides a pump shutdown command when required. Solutions for both new construction and retrofit are described.

Method and appartus for operation of pool cleaner with integral chlorine generator

ActiveUS20090282627A1Efficiently and effectively distributesUniform concentrationCellsPhotography auxillary processesTime segmentElectrical battery
An automated self-propelled pool cleaner having a housing, a water pump for moving water through the housing, drive means for moving the pool cleaner over the surface of the salt water pool to be cleaned, and an integral electrochemical chlorine generator mounted in the housing, includes a processor / controller that is programmed to activate the chlorine generator, the pump and drive means in predetermined operational sequences that minimize wear and tear on the water pump and drive means, while at the same time distribute and maintain a safe level of sanitizing chlorine in the pool, to thereby obviate the need for an in-line chlorinator or other chemical additive treatments; an optional automated sensor device can be provided to activate a secondary maintenance program which enables the pool cleaner to operate over prolonged periods of time as the sole means for filtering and sanitizing the pool water. An electrochemical cell manual mounting system permits the cell to be secured in place for operation and manually removed for maintenance, repair or replacement by the user without special tools or training.

Process to obtain water bodies larger than 15,000 m3 for recreational use with color, transparency and cleanness characteristics similar to swimming pools or tropical seas at low cost

The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, such as lakes or artificial lagoons, with excellent color, transparency and cleanness properties at low cost, which comprises the following steps:
    • a.—providing a structure able to contain a large water body larger than 15,000 m3;
    • b.—feeding the structure of step (a) with inlet water having iron and manganese levels lower than 1.5 ppm and turbidity lower than 5 NTU;
    • c.—measuring water pH, ideally it should be within a range lower than 7.8;
    • d.—adding an oxidizing agent to the water contained in the structure of step (a), with which a 600 mV minimal ORP is controlled in water for a minimal period of 4 hours and in maximal cycles of 48 hours;
    • e.—adding a flocculating agent in concentrations within 0.02 and 1 ppm with maximal frequencies of 6 days and cleaning the bottom of the structure of step (a) with a suction device to remove precipitated impurities from the bottom of said structure, together with the additional flocculants and;
    • f.—generating a displacement of surface water containing impurities and surface oils by means of the injection of inlet water according to step (b), which generates said displacement in such a way to remove said surface water by means of a system for impurities and surface oils removal arranged in the structure of step (a), which together with step (e) replaces traditional filtering.
The present invention also discloses a structure to contain large water bodies comprising a system for the removal of impurities and surface oils by means of skimmers and the suction device to clean said structure.

Water heater

InactiveUS6943325B2Eliminate riskEliminate the risk of corrosionBathsDouchesWater useElectronic controller
An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a pipe to heat the pipe which in turn heats the water flowing therethrough. The heater is highly efficient due to the direct contact of the wet heating surface with the water and provides a smooth seamless inner heating surface by eliminating the need to pass electrical leads into the wet region of the heater. This virtually eliminates the risk of leaks in the water heater due to bulkhead fittings. The invention further eliminates the need for a heating element to be contained in the inner wet region of a spa heater, thereby reducing the risk of corrosion. The water heater is used in combination with an electronic controller having a microprocessor to control and regulate the operation of the water heater. The water heater can be used with electrical, electro-mechanical, and mechanical control systems for spas and can be retrofitted into existing spa applications.

System for Controlling Water in an Aquatic Facility

A system for controlling water within an aquatic facility includes a water chemistry controller, a variable rate water pump adapted to move water in the facility, and a variable rate motor driver operationally coupled to the water pump for variably energizing the water pump. The variable rate motor driver is coupled to the water chemistry controller to allow the water chemistry controller to manage the operation of the water pump.
