摘要:
A swimming pool hydraulic suction fuse system. Implementations may include a fuse housing having a pump outlet, a drain inlet, and an air source. The hydraulic suction fuse system may also include a fuse assembly coupled into the fuse housing, the fuse assembly having a fuse body including a first section and a second section. An air intake may be coupled to the fuse body and a magnet assembly may be coupled to the first section of the fuse body. The magnet assembly may include a solid magnet. A fuse may be included, which may be coupled to the second section of the fuse body and include an attractor element coupled between a fuse cap and a fuse stem.

The swimming pool floor or spa floor drain assembly of the present invention includes a drain body having a mouth positionable in proximity to the pool wall to serve as a fluid flow inlet, a spaced apart fluid flow outlet positionable below the mouth and a sidewall interconnecting the mouth with the outlet to define a fluid flow chamber. The cross sectional area of the fluid flow chamber decreases from the mouth to the base. A fluid deflecting plug includes a comparatively large area top and a comparatively small area base. A sidewall interconnects the top and base to form the plug with a cross sectional area decreasing form the top to the base. A support structure positions the plug within the drain body such that at least a substantial portion of the plug sidewall is spaced apart from the drain body sidewall to define a fluid flow channel having a first comparatively larger cross sectional area in proximity to the drain body mouth and a second comparatively smaller cross sectional area in proximity to the drain body outlet. The variation in the cross sectional area from the drain body mouth to the drain body outlet provides a lower fluid flow velocity at the mouth than at the outlet when fluid is transferred from the pool through the floor drain assembly.

A multiple outlet valve includes a valve actuating mechanism driven by a turbine. Fluid entering the valve passes through a flow control member which determines the velocity of the fluid entering the turbine and thereby controls the frequency with which the valve operates. The valve further includes a gasket associated with a valve shut-off plate for preventing leakage of fluid between outlet chambers in the base.

Methods of relieving the suction force in a swimming pool or spa. A first method may include the steps of closing an aperture in a hydraulic suction fuse through magnetic force and opening the aperture by increasing suction force within the hydraulic suction fuse. Implementations of hydraulic suction fuses may also utilize a method of adjusting the fuse point of a hydraulic suction fuse. The method may include decoupling a magnet assembly from a first step having a first height, the first step contained in a fuse body contained in the hydraulic suction fuse. The method may also include rotating the magnet assembly and coupling the magnet assembly with a second step having a second height, the second step contained in the fuse body.

Lower region of a cylindrical nozzle stem is longitudinally slotted to provide flexible tines and the tines have outwardly projecting lands at their distal ends. The flexibility of the tines permits the nozzle stem to be force filled into and through a ribbed region of a surrounding retainer. Further, the flexible tines permit a cylindrical metal weight, and a weight cover to be slipped over the lower end of the nozzle stem to be held in place by the lands on the tines. No separate fasteners nor adhesives are required to hold the assembly together.

An anti-vortex, flush-mounted floor drain for swimming pools consists of a main housing, which is in the form of a hollow cylinder of a first predetermined diameter A drain opening is located in the top of the hollow cylinder; and the edges of the top of the cylinder are mounted flush with the floor of the swimming pool. A downwardly sloped lip extends from the top edge of the main housing and terminates in a circular opening in the top of the main housing. A solid circular cover is centrally mounted in this opening in the main housing, and is movable toward and away from the opening in the main housing to vary the size of the water inlet from the pool between the edge of the circular cover and the edge of the opening in the main housing. A drain pipe is connected to the main housing for withdrawing water from the housing. The large circular cover at the center of the drain prevents a vortex from occuring as a result of the suction of water passing outwardly through the drain pipe in the drain housing.

An ozone generator for providing ozone enriched air that comprises a body for defining a chamber for air flow therethrough and an ultraviolet lamp disposed in said chamber for irradiating the air passing through said chamber to convert oxygen molecules to ozone molecules. The device further comprises an air inlet for introducing air and a diffuser for diffusing the introduced air about said lamp. The diffuser has an annular flange with a plurality of apertures therein, said annular flange extending inwardly from a cylindrical portion encircling the annular flange, the cylindrical portion abutting and extending from the annular wall. The device further comprises an air outlet for discharging ozone enriched air.

A drain for swimming pools, spas, whirlpool baths, etc., includes a plurality of first orifices in communication with corresponding serpentine passageways to minimize hair or a body part from covering and entering the first orifices to a degree sufficient to entrap a bather. A plurality of second orifices independent of the first orifices and in fluid communication with one another through a peripheral passageway provide a flow of water from the peripheral passageway into the serpentine passageways to create an alternate water inflow path and reduce the pressure differential and possible entrapment that might occur should a body part or hair come in contact with or enter the first orifices. Moreover, a plurality of ridges are attendant the first orifices to reduce the likelihood of direct contact with the first orifices by a body part or hair.
