연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The invention claimed is: 1. A spray head 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 longitudinal axis and a fluid contact surface extending around the longitudinal axis and in fluid communication with the inlet, a whirl member configured to impart rotational movement about the longitudinal axis to water passing from the inlet to the second outlet, such that centrifugal force causes the water moving toward the second outlet to follow the fluid contact surface, and a reflector positioned intermediate the whirl member and the fluid contact surface to reverse the direction of water supplied from the whirl member, the direction of water again reversed from the reflector to the fluid contact surface to assist in providing uniform water flow to the fluid contact surface, wherein a continuous shield of water extends outwardly from the spray head in a sheet-like layer around the water stream and is spaced apart from the water stream, the water stream produced from the spray head by the first outlet having a substantially laminar flow. 2. The spray head of claim 1, wherein the first outlet is defined by a nozzle including a planar wall disposed perpendicular to the flow of water and an orifice formed within the wall. 3. The spray head of claim 2, wherein the wall has a thickness less than the diameter of the orifice. 4. The spray head of claim 2, further comprising a flow straightening member in fluid communication with the nozzle and configured to assist in removing turbulence from the water supplied to the orifice. 5. The spray head of claim 4, wherein the flow straightening member includes a plurality of parallel bores configured to provide a substantially linear flow of water. 6. The spray head of claim 1, wherein the cartridge is threadably coupled to the body. 7. The spray head of claim 1, wherein an annular passageway couples the inlet to the whirl member. 8. The spray head of claim 1, wherein the whirl member includes an annular body having a plurality of slots formed therein to rotate water outwardly about the longitudinal axis. 9. The spray head of claim 1, wherein the cartridge includes a discharge member including the fluid contact surface configured to produce the continuous shield of water through a Coanda effect. 10. The spray head of claim 9, wherein the fluid contact surface of the discharge member has a conical shape. 11. The spray head of claim 1, wherein the water stream produced by the first outlet is generally positioned at a center of the continuous shield of water produced by the second outlet. 12. The spray head of claim 11, wherein the continuous shield of water produced by the second outlet is at least one of substantially conical shaped and bulb shaped. 13. A spray head comprising: a body including a fluid port; a mount removably received within the body; a flow straightening member operably coupled to the mount and in fluid communication with the fluid port, the flow straightening member being configured to assist in removing turbulence from water; a nozzle operably coupled to the straightening member and including an outlet orifice configured to produce from the spray head a center water stream; and a whirl member operably coupled to the mount and extending around the flow straightening member, the whirl member including a body having a plurality of slots, a fluid passageway defined between the body of the whirl member and the flow strengthening member and in fluid communication with the fluid port, wherein the slots of the whirl member are configured to impart rotational movement to water supplied to a serpentine passageway between the whirl member and a fluid contact surface, such that water from the whirl member follows the fluid contact surface for producing from the spray head a continuous shield of water extending around the center water stream and spaced apart from the center water stream. 14. The spray head of claim 13, wherein the nozzle includes a cylindrical outer wall and the outlet orifice is formed within a planar wall disposed perpendicular to the outer wall to render the water stream passing therethrough substantially laminar. 15. The spray head of claim 14, wherein the planar wall has a thickness less than the diameter of the orifice. 16. The spray head of claim 15, wherein the flow straightening member includes a plurality of parallel bores configured to provide a substantially linear flow of water. 17. The spray head of claim 13, wherein an annular passageway couples the inlet to the whirl member. 18. The spray head of claim 17, wherein the whirl member includes an annular body having a plurality of slots formed therein rotate water outwardly about a longitudinal axis defined by the outlet orifice. 19. The spray head of claim 13, further comprising a back reflector concentrically received around the whirl member. 20. The spray head of claim 13, further comprising a second annular outlet concentrically received around the outlet orifice and configured to receive water from the whirl member and produce the continuous shield of water. 21. A method of generating a water pattern comprising the steps of: supplying water to a cartridge assembly having a first outlet and a second outlet; producing from the first outlet a center water stream having a substantially laminar flow; and producing from the second outlet an outer continuous shield of water extending outwardly in a sheet-like layer around the center water stream and spaced apart from the center water stream, including the steps of imparting rotational movement to the water, providing substantially uniform flow to the water by reversing a plurality of times the direction of water flow, and causing the rotating water to follow a fluid contact surface within the second outlet. 22. The method of claim 21, further comprising the step of producing from the first outlet a center water stream includes the step of removing turbulence from the center water stream to make it substantially laminar. 23. The method of claim 21, wherein the step of producing from the second outlet an outer continuous shield of water further includes the step of passing the water over a conical shaped surface. 24. A method of generating a water pattern with a water delivery device comprising the steps of: dividing a supply of water provided to the water delivery device into at least a first portion and a second portion; and supplying from an exterior of the water delivery device a stream of water based on the first portion and a continuous shield of water based on the second portion, the stream of water having a substantially laminar flow and the continuous shield of water rotating about a longitudinal axis of the stream of water and spaced apart from the stream of water, the continuous shield of water having a substantially uniform flow by reversing a plurality of times the direction of flow. 25. The method of claim 24, further comprising the step of passing the first portion of the water through a flow straightener having a plurality of longitudinal passageways, the flow straightener configured to remove turbulence from the first portion of the water. 26. The method of claim 24, further comprising the step of imparting a rotational movement to the second portion of the water. 27. The method of claim 26, further comprising the steps of directing the second portion of the water generally in a first direction followed by, directing the second portion of the water generally in a second direction opposite the first direction followed by, directing the second portion of the water generally in the first direction again. 28. The method of claim 26, wherein the second portion of the water contacts a Coanda effect surface.
