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.

This invention pertains to a brewing head assembly of a coffee machine that enables easy insertion and removal of the filter as well as locking of the filter and the filter holder into the brewing head to form a water-tight seal under pressure. The filter holder can be inserted into the brewing head assembly by sliding the filter holder into the brewing head assembly from the front, top, or side or by swinging the filter holder, which may be pivotally-attached to the brewing head assembly, into the coffee machine. The locking mechanism for inserting and securing the filter holder to the brewing head assembly may be motor-driven. Additionally, the motorized method for opening/closing and locking/unlocking the brewing head assembly may be operated by remote control. Furthermore, the boiler or heating system is may be maintained separately from the brewing head assembly.

We claim: 1. A brewing head of a coffee machine, comprising: (a) a rotate-to-lock assembly, which comprises a handle having two ends, wherein each end of said handle is movably-joined to one end of a rotate plate, rotate rod, and top frame by a fixed pin; wherein a portion of a back connection plate is fixedly-attached to the side of said top frame and the other portion of said back connection plate is movably-joined to a support base; wherein one end of a front connection plate is movably-joined to the other end of said rotate plate, and the other end of said front connection plate is movably-joined to said support base; and wherein a motor is connected to the rotate rod and handle, and wherein a remote control printed control board is connected to the motor; (b) a filter holder assembly, which comprises a filter, filter handle, filter holder, and coffee chamber; wherein the filter contains a flange; and (c) a sealing assembly, which comprises a seal ring, inserted between a water connection plate and a water spreader; wherein a water outlet valve, water outlet spring, said seal ring, and said water spreader are fixedly attached to the water connection plate by a water outlet valve holder; wherein the water connection plate is fixedly attached to the top frame; wherein the water connection plate contains an opening for connecting the water connection plate to a hose for delivering heated and/or pressurized fluid from a boiler, in the closed position, the handle is rotated downward to move the front connection plate to a vertical position; wherein the seal ring forms an air-and water-tight seal with the flange of the filter; wherein the rotate-to-lock assembly, the filter holder assembly, and the sealing assembly are operatively-linked to sustain pressures up to twenty bars. 2. The brewing head according claim 1, wherein the filter holder assembly comprises a flange to provide linear sliding movement of the cabinet filter holder relative to the brewing head. 3. The brewing head according to claim 1, additionally comprising means connected to the motor for enabling the motor to be operated remotely. 4. The brewing head of claim 1, further comprising means for producing and delivering hot fluid to the brewing head. 5. A brewing head of a coffee machine, comprising: (a) a rotate-to-lock assembly, which comprises a handle having two ends; wherein each end of the handle is movably joined to a cam pin and a top frame; wherein each cam pin rotates a back connection plate; wherein one member of each back connection plate is fixably attached to each side of the top frame by hinge pins and movably joined to each of the cam pins; wherein the other member of each back connection plate is pivotally joined to a support base; and wherein a motor is connected to the cam pin and handle, and wherein a remote control printed control board is connected to the motor; (b) a filter holder assembly, which comprises a filter, a filter handle, a filter holder, and a coffee chamber; wherein the filter contains a flange; and (c) a sealing assembly, which comprises a seal ring, inserted between a water connection plate and a water spreader; wherein a water outlet valve, a water outlet spring, the seal ring, the water spreader are fixedly attached to the water connection plate by a water outlet valve holder; wherein the water connection plate is fixedly attached to the top frame; wherein the water connection plate contains an opening for connecting the water connection plate to a hose for delivering heated and/or pressurized fluid from a boiler, in the closed position, the handle is rotated downward to lower the connection plate; wherein the seal ring forms a pressure-and/or water-tight seal with the flange of the filter; wherein the rotate-to-lock assembly, the filter holder assembly and the sealing assembly are operatively linked to sustain pressure up to twenty bars. 6. The brewing head according claim 5, wherein the filter holder assembly comprises a flange to provide sliding movement of the cabinet filter holder assembly relative to the brewing head. 7. The brewing head according to claim 6, additionally comprising means connected to the motor for enabling the sliding movement of the cabinet filter holder to be operated remotely. 8. The brewing head according to claim 5, additionally comprising means connected to the motor for enabling the motor to be operated remotely. 9. The brewing head of claim 5, further comprising a means for producing and delivering hot fluid to the brewing head unit. 10. A brewing head of a coffee machine, comprising: (a) a rotate-to-lock assembly, which comprises a handle having two ends, wherein each end of the handle is joined to a rotation pole having a protruding member, wherein each rotation pole is movably attached to a protruding member of a support base, wherein the protruding member is movably joined to one end of a moving rod, wherein the other end of the moving rod is movably joined to a upper protruding member of a slider plate, wherein the movement of the slider plate is guided by the slider plate holder attached the support base; wherein a shower head is attached to the bottom of the slider plate; and wherein a motor is connected to the rotation pole and handle, and wherein a remote control printed control board is connected to the motor; (b) a filter holder assembly, which comprises a filter, a filter basket, a filter handle, a filter holder and a coffee chamber; wherein the filter contains a flange; and (c) a sealing assembly, which comprises a seal ring fixed on the shower head; wherein a water spreader is attached to the shower head by a spreader holder; wherein the pressurized or heated fluid and/or steam from the boiler is delivered to the shower head by a tube or pipe, in the closed position, the handle is rotated downward to move the rotation pole, which causes the moving rod to swing or move downward; wherein the slider plate which is attached to one end of the moving rod lowers the shower head onto the filter basket; wherein the seal ring on the shower head forms a water-and pressure-tight seal, capable of sustaining pressures up to 20 bars. 11. The brewing head according to claim 10, wherein the filter holder assembly further comprises a foam system for producing foam coffee or coffee with froth. 12. The brewing head according to claim 11, wherein the foam system is attached to the bottom of the filter basket. 13. The brewing head according to claim 10, wherein the rotate-to-lock assembly further comprises a stopper attached to at least one protruding member of the support base. 14. The brewing head according to claim 10, wherein the motor for opening and closing the rotate-to-lock assembly is operated by a remote control. 15. The brewing head of claim 10, further comprising means for producing and delivering hot fluid to the brewing head.
