Abstract
An improved filter capable of operating in a backwash mode that creates an upward swirling flow in the hollow interior of the pool filter container. During the backwash cycle, water or air and water are injected into the pool filter container at an angle. In the preferred embodiment, a mixture of water and air are injected into the filter container through exit jets located within the hollow interior of the filter container proximate to the bottom of the filter container. This causes the filter media to swirl upward mixing thoroughly with the backwash water promoting the separation of the mineral deposits from the filter media.
Claims20
A pool filter capable of operating in a normal mode and in a backwash mode, comprising:
- a. a filter container having a hollow interior and a bottom;
- b. said hollow interior being configured to receive a volume of filter media;
- c. a plurality of intake inlets located within said hollow interior proximate said bottom;
- d. wherein when said pool filter is operating in said normal mode and when said volume of filter media is in position, said plurality of intake inlets draw in water through said filter media;
- e. a plurality of exit jets located within said hollow interior proximate said bottom;
- f. wherein when said pool filter is operating in said backwash mode, said plurality of exit jets expel water upward through said filter media;
- and
- g. wherein each of said plurality of exit jets is tilted off of vertical such that said plurality of exit jets acting in unison, when said pool filter is operating in said backwash mode, create a swirling flow within said hollow interior.
A pool filter capable of operating in a normal mode and in a backwash mode, comprising:
- a. a filter container having a hollow interior and a bottom;
- b. said hollow interior being configured to receive a volume of filter media;
- c. a plurality of intake inlets located within said hollow interior proximate said bottom;
- d. wherein when said pool filter is operating in said normal mode and when said volume of filter media is in position, said plurality of intake inlets draw in water through said filter media;
- e. an injector manifold located proximate said bottom;
- f. wherein said injector manifold has a plurality of conduits configured to fluidly connect with said bottom of said filter;
- g. wherein when said pool filter is operating in said backwash mode, said plurality of conduits expel a fluid upward through said filter media;
- and
- h. wherein each of said plurality of conduits is tilted off of vertical such that said plurality of conduits acting in unison, when said pool filter is operating in said backwash mode, create a swirling flow within said hollow interior.
