Abstract
A spray head for a power sprayer configured to generate a continuous sheet-like water shield around a center stream of water is disclosed. A water delivery device for use with a sink is disclosed, the water delivery device may produce a stream of water surrounded by a continuous shield of water.
Claims28
A water delivery system for connection to at least one source of water and for mounting to a sink deck, the water delivery system comprising:
- at least one valve adapted to be in communication with the at least one source of water;
- and
- an output device coupled to the sink deck, the output device having an internal waterway and a spray head, the internal waterway being in fluid communication with the valve and with the spray head, wherein the spray head includes a first outlet producing a stream of water from the spray head and a second outlet producing a continuous shield of water from the spray head, the continuous shield of water rotating about a longitudinal axis of the stream of water and being spaced apart from the stream of water.
A spray head for use with a water delivery system comprising:
- a body including a fluid port configured to be coupled to a water supply;
- and
- a cartridge received within the body, the cartridge including an inlet in fluid communication with the fluid port, a first outlet in fluid communication with the inlet and configured to produce from the spray head a water stream, a second outlet having a fluid contact surface and in fluid communication with the inlet, and a whirl member configured to impart rotational movement to water passing from the inlet to the second outlet, the cartridge being configured to decrease turbulence in water moving toward the second outlet and provide a substantially uniform water flow to the fluid contact surface, wherein the water from the second outlet is configured to produce a continuous shield of water extending outwardly from the spray head in a sheet-like layer around the water stream and spaced apart from the water stream.
A method of generating a plurality of water outputs from a spray head of a water delivery system comprising the steps of:
- providing at least one valve adapted to be in fluid communication with at least one source of water;
- opening the at least one valve;
- providing an output device having an internal waterway and a spray head, the internal waterway being in fluid communication with the at least one valve and with the spray head;
- supplying water to a first outlet within the spray head to produce a stream of water;
- supplying water to a second outlet within the spray head, the second outlet generally surrounding the first outlet;
- and
- rotating the water supplied to the second outlet about a longitudinal axis of the stream of water, thereby generating a continuous shield of water spaced apart from the stream of water.
