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.
1. 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 at least one valve and with the spray head, wherein the spray head includes a first outlet defining a longitudinal axis and producing a stream of water from the spray head along the longitudinal axis, and a second outlet having a stationary contact surface facing inwardly toward the longitudinal axis and flared outwardly at a downstream end, the second outlet being continuous and surrounding the first outlet, and a stationary whirl member coupled to the second outlet and positioned upstream from the contact surface, the whirl member including rotationally fixed slots configured to impart rotational movement to water passing to the second outlet, such that water moving to the second outlet is propelled radially outwardly due to centrifuged force for following the contact surface and producing a continuous shield of water from the spray head, the continuous shield of water rotating about the longitudinal axis of the stream of water and being spaced apart from the stream of water.
2. The water delivery system of claim 1 , wherein the stream of water produced by the first outlet has a substantially laminar flow.
3. The water delivery system of claim 2 , wherein the output device further includes a spout base member, the spray head being coupled to the spout base member.
4. The water delivery system of claim 3 , wherein the spray head is moveable relative to the spout base member.
5. The water delivery system of claim 4 , wherein the spray head is a swivel spray head.
6. The water delivery system of claim 4 , wherein the spray head is a pull out portion moveable between a first position coupled to the spout base member and a second position spaced apart from the spout base member.
7. The water delivery system of claim 1 , further comprising a spout in fluid communication with the at least one valve and coupled to the sink deck, and wherein the output device is a side spray to couple the sink deck in spaced relation to the spout.
8. The water delivery system of claim 7 , wherein the side spray is movable between a first position generally supported by the sink deck to a second position spaced apart from the sink deck.
9. The water delivery system of claim 1 , wherein the valve is positioned below the sink deck.
10. The water delivery system of claim 1 , wherein the stream of water is a central stream of water.
11. The water delivery system of claim 1 , wherein the whirl member includes an annular body defining a central opening and the rotationally fixed slots, wherein the slots are circumferentially spaced within the annular body and in fluid communication with the central opening for imparting rotational movement to water passing to the second outlet.
12. A water delivery system comprising:
at least one valve adapted to be in communication with at least one source of water;
an internal waterway in fluid communication with the at least one valve; and
a spray head in fluid communication with the at least one valve, wherein the spray head includes a first outlet defining a longitudinal axis and producing a stream of water from the spray head along the longitudinal axis, and a second outlet having a stationary contact surface facing inwardly toward the longitudinal axis and flared outwardly at a downstream end, the second outlet being continuous and surrounding the first outlet, and a stationary whirl member coupled to the second outlet and positioned upstream from the contact surface, the whirl member including rotationally fixed slots configured to impart rotational movement to water passing to the second outlet, such that water moving to the second outlet is propelled radially outwardly due to centrifuged force for following the contact surface and producing a continuous shield of water from the spray head, the continuous shield of water rotating about the longitudinal axis of the stream of water and being spaced apart from the stream of water.
13. The water delivery system of claim 12 , wherein the stream of water produced by the first outlet has a substantially laminar flow.
14. The water delivery system of claim 12 , further comprising a spout in fluid communication with the at least one valve and coupled to a sink deck, and wherein the spray head is supported by a side spray coupled to the sink deck in spaced relation to the spout.
15. The water delivery system of claim 12 , wherein the valve is positioned below the sink deck.
16. The water delivery system of claim 12 , wherein the whirl member includes an annular body defining a central opening and the rotationally fixed slots, wherein the slots are circumferentially spaced within the annular body and in fluid communication with the central opening for imparting rotational movement to water passing to the second outlet.
