A modular filter system using replaceable filter cartridges includes matching adaptor rings in the filter head and on the filter cartridge placed at selected circumferential positions to ensure proper cartridge fit and to provide a proprietary cartridge construction for selected users. The adaptor rings operate only to control cartridge to filter head fit and are not used to drive the rotary valve spindle.

Filter cartridges and methods of use with manifolds of appliances. The filter cartridges can includes components, such as handles, levers, cams, rotatable nuts, actuators, pins, and springs, to assist in removing the filter cartridge from the manifold. Some embodiments of the filter cartridges can include a neck having a non-uniform diameter over a longitudinal length. Other embodiments of the filter cartridges can include a recess that receives a portion of the manifold and the recess can have at least one seal. One embodiment of the invention provides an adapter for use between a manifold and a filter.

A head rest assembly is provided for use in conjunction with a bathing fixture such as a hydro-massage whirlpool. A pillow is provided which can be easily connected and supported by the jet nozzle assembly. A support bracket is partially enclosed in the pillow for connection with the nozzle assembly. The nozzle assembly has a living hinge feature which allows adaptation to various curvatures of the tub wall. A magnet can be connected to a bracket and a reed switch is connected to the nozzle assembly which serves as a safety feature.

The valve spindle for a reverse osmosis (RO) filter system is housed in a filter head and attached to a mounting ring that also carries the replaceable RO cartridge. The RO spindle is locked in the head during normal operation, but can be easily removed, after removal of the cartridge, to permit spindle replacement or repair without disassembly of the head from the mounting bracket.

A cartridge for a water treatment system, effective to assist in the removal of contaminants by photocatalytic oxidation and by adsorption, includes a plurality of stacked disks, preferably made of a UV light transmissive material, which disks define circuitous flow paths for water being treated. In a preferred embodiment, the disk surfaces contacted by the water are provided with a coating of a catalyst, such as TiO2, activated by a UV light source positioned in the center of the cartridge.

A whirlpool tub has a first set of nozzles located to direct water against the back of a bather and a second set of nozzles to direct water against the bather's neck. A controller has different modes of operation in which water is emitted by either one or both sets of nozzles. Separate mechanisms are provided to direct a pulse of water sequentially through different nozzles in each set. This action produces a progression of pulsating water jets that create a massaging effect on the bather's skin. A pillow is placed about the second set of nozzles. A sensor is provided to detect when the pillow is removed and disable water flow through the second set of nozzles.

A flushing mechanism for a toilet triggers a flush in response to the closing of the toilet seat cover. A magnet is attached to the seat cover and detected by a sensor. The sensor activates a battery powered motor having a crank arm which directly raises a flapper valve by means of a tensile link. The sensor and motor unit are suspended out of sight in the tank of the toilet by flanges fitting between the tank rim and the tank top. The flanges allow adjustment of the motor and sensor to a variety of preexisting tank type toilets for effective retrofitting. A delay timer prevents repeated energy wasting flushing of the toilet.
摘要:
A multipurpose jet manifold arrangement for use in conjunction with hydro-massage spas and whirlpools. The manifold arrangement can be plumbed to both water and air from various positions so as to facilitate use at various locations in the tub. Further, it can be easily severed into separate single nozzle housings for use as a single nozzle. In a preferred manner, the manifold arrangement is molded from a plastic material.

A rotary valve spindle for flow control in the head of a filter includes a unitary dual function seal that is carried by the spindle and seals against the inner surface of the filter head during spindle rotation between flow and no-flow positions. The dual function seal greatly simplifies manufacture and assembly of the valve.
