Abstract
A filter for a spa or pool, having a filter body which receives a filter bag having a sheath encompassing the exterior of the filter body and a pocket extending inwardly from the front end of the sheath into the filter. Operation of the spa water circulation system draws spa water into the filter bag pocket while concurrently spa water is drawn transversely through the filter bag sheath and auxiliary spa water openings into the filter body. An O-ring encircles the upper portion of the filter bag to releasably retain such bag to the filter body during operation of the spa water circulation system.
Claims20
A filter for connecting water from a contained body of water to the suction end of a water circulation system for such body of water, such circulation system including a pump with a suction end and a discharge end, said filter comprising:
- a filter body that includes a cylinder having a water inlet opening at one end and a water discharge orifice at its opposite end, the sides of such cylinder being formed with auxiliary water inlet openings;
- a filter bag that includes a cylindrical sheath which extends from the first-mentioned water inlet opening end of the filter body encompassing the exterior of the filter body, such filter bag also being formed with a pocket that extends concentrically inwardly from the water inlet opening end of the sheath longitudinally into the filter body from the first-mentioned water inlet opening;
- a retainer removably securing the filter bag upon the filter body;
- and
- with the filter body discharge opening being connectible with the suction end of the water circulation system pump whereby upon operation of the pump water is drawn from said body of water into the first-mentioned water inlet opening, and the auxiliary water inlet openings, through the filter bag and then out of the water discharge opening of the filter.
In a filter for use in a water circulating system, wherein the filter includes a filter body having a vertically extending cylinder formed with a water inlet opening at its upper end and a water discharge orifice at its lower end, the sides of such cylinder being formed with auxiliary water inlet openings:
- a filter bag having a cylindrical sheath which extends longitudinally from the water inlet end of the filter body over the exterior of the filter body, such filter bag also being formed with a pocket that extends concentrically longitudinally from the water inlet end of the sheath into the filter body from the water inlet opening;
- a retainer removably securing the filter bag upon the filter body;
- and
- whereby upon operation of the water circulating system water is drawn longitudinally into the main water inlet opening and through the filter bag pocket into the interior of the filter body while concurrently water is drawn transversely through the filter bag sheath and auxiliary water openings into the confines of the filter body, with all of such water flowing downwardly out of the filter body through the filter body discharge orifice.
A filter bag for use in a water circulation system that includes a filter having a filter body which includes a vertically extending cylinder formed with a water inlet opening at its upper end and a water discharge orifice at its lower end, the sides of such cylinder being formed with auxiliary water inlet openings, said filter bag comprising a cylindrical sheath which extends upwardly from the lower end of the filter body to the upper end of such filter body, the sheath encompassing the exterior of the filter body, such filter bag also being formed with a pocket that extends concentrically downwardly from the upper end of the sheath into the filter body from the water inlet opening of the filter body, whereby upon operation of the water circulating system water is drawn from such system downwardly into the filter body's main water inlet opening and through the filter bag pocket into the interior of the filter body while concurrently water from such system is drawn transversely through the filter bag sheath and auxiliary water openings into the confines of the filer body, with all of such water flowing downwardly out of the filter body through the filter body discharge orifice back into the water circulation system;
- and
- retainer that engages the filter bag to releasably secure such filter bag to the vertically extending cylinder during operation of the water circulation system.
