Abstract
An integrated process and system for the cleaning of any body of water in need of periodic cleaning, including but not limited to a swimming pool or spa. A submersible water filtration apparatus comprises a housing unit, an impeller driven by an electric motor powered by batteries, an inlet where fluid, such as water, is drawn inwards into the submersible water filtration apparatus, an outlet for returning filtered water into the body of water, and at least one filter zone.
Claims22
A submersible water filtration apparatus for filtering water in a body of water comprising:
- a filter unit including:
- a filter housing defining a chamber therein;
- a filter unit inlet in fluid communication with the chamber of the filter housing;
- and
- a filter unit outlet in fluid communication with the chamber of the filter housing;
- an electric motor coupled to an impeller, said electric motor and impeller engaged with the filter unit to pump water from the body of water through said filter unit inlet and discharge filtered water out of said filter unit via the filter unit outlet;
- a power source for supplying an electrical current to the electric motor;
- and
- at least one flow conditioning element for reducing current draw from the power source.
A submersible water filtration apparatus for filtering water in a body of water:
- a filter unit including:
- a filter housing defining a chamber therein;
- a filter unit inlet in fluid communication with the chamber of the filter housing;
- and
- a filter unit outlet in fluid communication with the chamber of the filter housing;
- at least one filter placement structure for ordering of one or more filters within the chamber of the filter housing;
- at least a first water filter and a second water filter positioned within the chamber of the filter housing, wherein said first water filter is more porous than the second water filter;
- wherein the first water filter and the second water filter engage with the at least one filter placement structure to position the first water filter upstream of the second water filter within the filter unit;
- an electric motor coupled to an impeller, said electric motor and impeller engaged with the filter unit to pump water from the body of water through said filter unit inlet, through said first and second water filters and discharge filtered water out of said filter unit via the filter unit outlet.
A submersible water filtration apparatus for filtering water in a body of water comprising:
- a filter unit including:
- a filter housing defining a chamber therein;
- a filter unit inlet in fluid communication with the chamber of the filter housing;
- and
- a filter unit outlet in fluid communication with the chamber of the filter housing;
- at least one water filter positioned within the chamber of the filter housing;
- a recirculation outlet positioned within the body of water, proximate to the apparatus inlet such that water discharged from said recirculation outlet is expelled into the body of water toward the apparatus inlet before at least some of the water discharged from said recirculation outlet reenters through the apparatus inlet;
- a recirculation conduit allowing fluid communication between the filter unit outlet and the recirculation outlet;
- an electric motor coupled to an impeller, said electric motor and impeller engaged with the filter unit to pump water from the body of water through said filter unit inlet, through said at least one water filter, through said filter unit outlet, through said recirculation conduit, and discharge filtered water out of an outlet.
A submersible water filtration apparatus for filtering water in a body of water comprising:
- a vacuum head having one or more than one height adjustment assembly for adjusting a height of the vacuum head among a plurality of height positions;
- a filter unit including:
- a filter housing defining a chamber therein;
- a filter unit inlet extending from the vacuum head and in fluid communication with the chamber of the filter housing;
- and
- a filter unit outlet in fluid communication with the chamber of the filter housing;
- an electric motor coupled to an impeller, said electric motor and impeller engaged with the filter unit to pump water from the body of water through said filter unit inlet and discharge filtered water out of said filter unit via the filter unit outlet;
- and
- a power source for supplying an electrical current to the electric motor.
