摘要:
Detailed are actuators especially useful in connection with valves forming parts of water-recirculation systems of pools or spas. Transit times of components of the actuators may be measured or otherwise determined and signals sent to the actuators to cease movement of the components between boundary positions. Consequently, dynamic adjustment of the valving capabilities of the systems may be achieved.
摘要:
Assemblies designed to facilitate detection of water flow in low water flow situations. In some embodiments, the assembly includes a channel that narrows from an inlet end of the assembly to an outlet end of the assembly to increase the velocity of water flowing through the channel. In some embodiments, the assembly may also include a water delivery mechanism that delivers water flowing through the channel to a flow sensor and enables the detection of water flow, even in low flow situations.
摘要:
Components of automatic pool cleaners (APCs) are detailed. The components may include brushes configured to attach to blades of scrubbers of the APCs. The flexible brushes may rotate as their associated blades rotate and have fingers which flex so as to adduce contact between a to-be-cleaned pool or spa surface and bristles protruding outward from sides of the fingers.
摘要:
Generation of electricity on-board, principally, certain hydraulic pool cleaners is described. Magnets may be caused to move within coils by (normal) cooperative actions of diaphragm-type valves and external pumps, thus generating electricity without changing the operational principles of the cleaners. The generated electricity may be used to power electrical devices either on-board the cleaners or elsewhere.
摘要:
Described are cleaning devices intended for immersion in water of swimming pools and spas. The devices beneficially may be pressure-side cleaners attached indirectly to outlets of water-circulation pumps. The supply of pressurized water travelling from a pump to such a device may be employed for various purposes, including directing debris-laden water to or near tops of debris collection chambers. The water exiting nozzles associated with the devices may push, rather than pull, the debris-laden water toward the collection chambers. Some nozzles may be oriented approximately parallel to a to-be-cleaned pool surface, and curved tubes may be employed to direct water and debris flow to perimeters of the cleaners.
摘要:
Described are systems and methods for controlling pool and spa equipment. A device may communicate wirelessly with pool and spa controls directly (point-to-point) as well as indirectly, either via the Internet or as part of a local area network (LAN). The device may be a smart phone, tablet, or other appropriate apparatus.
摘要:
Systems and methods for circulating water of swimming pools or spas are detailed. The systems may include both a main filtration pump and a secondary booster pump, with the booster pump containing a variable-speed motor. By adjusting motor speed of the booster pump, pressurized water may be supplied to certain automatic swimming pool cleaners more efficiently, without need for energy-wasting by-pass paths or restrictor plates.
摘要:
Systems and methods of retrofitting an existing mechanical time clock enclosure to an Internet controllable, electronic pool and/or spa controller with improved, multi-functionality. In some instances, the conversion can be made without the need for adding new, additional enclosures (and corresponding wiring) and can expand the functionality of the controller to operate one or more valve actuators, one or more circuits, provide two-way communication with variable speed pumps and/or allow the electronic controller to access and/or be controlled by the Internet or with interface software.
摘要:
Fluid-powered devices are detailed. The devices may be utilized as motors or pumps, for example, and are capable to switching dynamically between these functions. They additionally may use surface-area, rather than solely pressure, differentials to produce rotary motion.
摘要:
Systems and methods of (remotely) controlling aspects of pools and spas and of modifying water contained therein are detailed. Internet-enabled access to pool and spa controllers may happen without any need for users to create firewall ports or utilize static internet protocol addresses. Certain networking devices may be configured using a USB connection or SD card, avoiding any requirement for an Ethernet cable or supplying separate power to the devices during configuration. Time-varying data may be obtained in respect of one or more installations and analyzed for various information.
