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, Kafe, Webinar 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.

A sprayhead especially suited for coupling to an extension hose for use in a pull-out kitchen faucet, the sprayhead including a selector subassembly for choosing between both spray and aerate modes, and a volume control built in to the sprayhead. The selector subassembly is engaged to a detent finger-button mounted on the housing that selectively diverts water flowing through an aerated flow path to an alternate spray flow path, thereby allowing manual selection between spray mode and aerate mode. The volume control is a slide switch on the housing and coupled to a rotary valve assembly for allowing the user to adjust the flow volume when in spray mode without affecting water volume in the aerate mode. When in aerate mode water is expelled from the sprayhead through an aerator output, and when in spray mode water is expelled through a series of nozzles oriented radially around the aerator output.

I claim: 1. A sprayhead for connection to a faucet for expelling water, comprising: a sprayhead housing a first control comprising a detent finger-button in the sprayhead housing for allowing a user to manually select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; and second control in the sprayhead housing for allowing said user to adjust a flow volume of water expelled from said sprayhead. 2. A sprayhead for connection to a faucet for expelling water, comprising: a sprayhead housing a first control in the sprayhead housing for allowing a user to manually select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; and a second control in the sprayhead housing comprising a slide switch for allowing said user to adjust a flow volume of water expelled from said sprayhead. 3. The sprayhead for expelling water according to claim 2, wherein said second control adjusts the volume of water expelled from said spray head when in spray mode. 4. The sprayhead for expelling water according to claim 1, wherein said detent finger-button remains in a normally unbiased first position for said aerate mode, and is depressed to a second biased position for selection of spray mode. 5. The sprayhead for expelling water according to claim 2, wherein said slide switch is adjusted within a range of positions and, when released, maintains a position. 6. The sprayhead for expelling water according to claim 2, wherein said second control comprises a ring gear. 7. The sprayhead for expelling water according to claim 6, wherein said ring gear comprises an annular collar with gear teeth, said slide switch being formed integral to said collar. 8. A sprayhead for connection to a faucet for expelling water, comprising: a sprayhead housing a first control in the sprayhead housing for allowing a user to manually select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; a second control in the sprayhead housing for allowing said user to adjust a flow volume of water expelled from said sprayhead; a plurality of conduits defining a water input path in fluid communication with a spray flow path and an aerated flow path; and a diverter chamber interrupting said aerated flow path, said first control including a movable piston loaded into said diverter chamber for selectively interrupting the aerated flow path to divert water into the spray flow path. 9. A sprayhead for connection to a faucet for expelling water, comprising: a sprayhead housing a first control comprising a selector sub-assembly in the sprayhead housing for allowing a user to manually select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; a second control in the sprayhead housing for allowing said user to adjust a flow volume of water expelled from said sprayhead; and a plurality of conduits defining a water input path, a spray flow path in fluid communication between said input path and a spray outlet, an aerated flow path in fluid communication between said input path and an aerated outlet, and a diverter chamber interrupting said aerated flow path, said selector sub-assembly including a movable piston loaded into said diverter chamber for selectively interrupting the aerated flow path to divert water into the spray flow path. 10. The sprayhead for expelling water according to claim 9, wherein said movable piston is moved within said diverter chamber by a detent finger-button for selection between said spray mode and said aerate mode. 11. A sprayhead for connection to a faucet for expelling water from said faucet, comprising: an outer sprayhead housing a first control comprising a detent finger-button in the sprayhead housing for selecting one of a spray mode and an aerate mode: and said aerate mode; a second control in the sprayhead housing for adjusting a flow volume; a conduit assembly having a first flow path for said spray mode and a second flow path for said aerate mode; a mode selector sub-assembly enclosed within said housing in cooperation with said first control for selecting one of said first flow path and said second flow path; a flow control assembly enclosed within said housing in cooperation with said second control for adjusting water flow volume in said second flow path. 12.

A sprayhead for connection to a faucet for expelling water from said faucet, comprising: an outer sprayhead housing a first control in the sprayhead housing for selecting one of a spray mode and an aerate mode; a second control in the sprayhead housing for adjusting the flow volume of water in spray mode, but having no affect on flow volume in aerate mode; a conduit assembly having a first flow path for said spray mode and a second flow path for said aerate mode; a mode selector sub-assembly enclosed within said housing in cooperation with said first control for selecting one of said first flow path and said second flow path; a flow control assembly enclosed within said housing in cooperation with said second control for adjusting water flow volume in said second flow path. 14. The sprayhead for expelling water according to claim 11, wherein said detent finger-button remains in a normally unbiased first position for said aerate mode, and is depressed to a second biased position for selection of spray mode. 15. The sprayhead for expelling water according to claim 12, wherein said slide switch is adjusted within a range of positions and, when released, maintains a position. 16. A method of controlling a flow of water from a faucet through a sprayhead coupled to said faucet, comprising the steps of: pressing a first control comprising a detent fingerbutton in the sprayhead and exteriorly accessible there from to select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; and using a second control in the sprayhead and exteriorly accessible there from to adjust a flow volume of water. 17. A method of controlling a flow of water from a faucet through a sprayhead coupled to said faucet, comprising the steps of: using a first control in the sprayhead and exteriorly accessible there from to select between a spray mode for expelling a spray of water, and an aerate mode for expelling an aerated stream of water; and sliding a second control comprising a slide switch in the sprayhead and exteriorly accessible there from to adjust a flow volume of water.
