Abstract
Skimming devices may use pressurized water from, for example, a return line of a swimming pool or spa. The devices may be adjustable vertically and levelled relative to an upper water surface (waterline) of a pool. They additionally may create “blades” of debris-laden pool water entering their floating heads so as to move debris smoothly and efficiently over wings or foils into associated filters.
Claims13
A skimming device comprising:
- means for receiving pressurized water;
- a wing or foil configured to extend at least partially above a waterline of a pool;
- a filter;
- and
- means for causing the pressurized water to flow as a blade of water upwards and over the wing or foil so as to draw water and debris of a pool over the wing or foil into the filter, wherein a portion of the wing or foil is inserted into the means for causing the pressurized water to flow, and wherein the means for causing the pressurized water to flow as the blade of water is upstream from the wing or foil.
2 more elements
A method comprising:
- receiving pressurized water of a pool through an inlet of a head of a skimming device;
- forming, by a portion of a wing or foil inserted in a channel of the head of the skimming device, a blade of water from the pressurized water upwards and over the wing or foil, wherein the wing or foil extends at least partially above a waterline of the pool and the blade of water is formed between a lid and a lower assembly of the head of the skimming device;
- and
- entraining water and debris in the blade of water in a filter of the lower assembly of the skimming device.
1 more element
A skimming device comprising:
- means for receiving pressurized water;
- a lid comprising a wing or foil;
- a lower assembly attachable to the lid, the lower assembly comprising a filter attachable to the lid;
- and
- means for causing the pressurized water to flow upwards and over the wing or foil as a blade of water between the lid and the lower assembly so as to draw water and debris of a pool over the wing or foil into the filter, wherein a portion of the wing or foil is inserted into the means for causing the pressurized water to flow.
