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.

What is claimed is: 1. A coffeemaker comprising: a plurality of infusion heads that can each receive a predetermined quantity of a product to be infused; a common hydraulic circuit comprising, connected in series: a water reservoir; a flow meter for measuring the rate of flow of water from said reservoir; a pump; a heater; and a plurality of parallel outlet tubes each connected to an outlet of said heater, said pump being operative to deliver water from said reservoir to said heater and said flow meter being connected between said reservoir and said pump; control means connected to said flow meter and said pump for controlling the operation of said coffeemaker; and distribution means connected in series with each of said outlet tubes and connected to be controlled by said control means for delivering water or steam to each of said infusion heads as a function of signals received from said flow meter, wherein said flow meter is the only meter between said reservoir and said pump, and said outlet tubes are connected directly to said outlet of said heater. 2. The coffeemaker of claim 1, further comprising means for producing steam to be delivered to at least one of said infusion heads. 3. The coffeemaker of claim 1, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 4. The coffeemaker of claim 1, wherein said plurality of infusion heads consist of two infusion heads. 5. The coffeemaker of claim 4, further comprising means for producing steam to be delivered to at least one of said infusion heads. 6. The coffeemaker of claim 4, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 7. The coffeemaker of claim 4, wherein said distribution means comprise at least one electrically controlled valve. 8. The coffeemaker of claim 7, further comprising means for producing steam to be delivered to at least one of said infusion heads. 9. The coffeemaker of claim 7, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 10. The coffeemaker of claim 4, wherein said distribution means comprise two two-way electrically controlled valves each connected for delivering water or steam from said heater to a respective one of said infusion heads. 11. The coffeemaker of claim 10, further comprising means for producing steam to be delivered to at least one of said infusion heads. 12. The coffeemaker of claim 10, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 13. The coffeemaker of claim 10, wherein each of said valves is a direct acting valve having an inactive state in which said valve is closed. 14. The coffeemaker of claim 13, further comprising means for producing steam to be delivered to at least one of said infusion heads. 15. The coffeemaker of claim 13, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 16. The coffeemaker of claim 13, wherein said control means are operative to control the operation of said two valves in order to produce alternating opening and closing cycles with a time interval during which both valves are simultaneously closed. 17. The coffeemaker of claim 16, further comprising means for producing steam to be delivered to at least one of said infusion heads. 18. The coffeemaker of claim 16, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 19. The coffeemaker of claim 10 wherein said control means are operative to control the operation of said two valves in order to produce alternating opening and closing cycles with a time interval during which both valves are simultaneously closed. 20. The coffeemaker of claim 19, further comprising means for producing steam to be delivered to at least one of said infusion heads. 21. The coffeemaker of claim 19, wherein said pump is adapted to operate at low pressure to deliver water through a flexible packet disposed in at least one of said infusion heads. 22. The coffeemaker of claim 1, wherein said reservoir has a water outlet connected directly to a water inlet of said flow meter. 23. A coffeemaker comprising: a plurality of infusion heads that can each receive a predetermined quantity of a product to be infused; a common hydraulic circuit comprising, connected in series: a water reservoir; a flow meter for measuring the rate of flow of water from said reservoir; a pump; a heater; and a plurality of parallel outlet tubes each connected to an outlet of said heater, said pump being operative to deliver water from said reservoir to said heater and said flow meter being connected between said reservoir and said pump; control means connected to said flow meter and said pump for controlling the operation of said coffeemaker; and distribution means connected in series with each of said outlet tubes and connected to be controlled by said control means for delivering water or steam to each of said infusion heads as a function of signals received from said flow meter, wherein said flow meter is the only flow meter in said coffeemaker, and said outlet tubes are connected directly to said outlet of said heater.
