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 rotatable shelf for use in a refrigerator that may include a support bracket configured to support a turntable but is not required. A bearing ring may be disposed between the support bracket and the turntable, wherein the bearing ring is configured to facilitate the rotation of the turntable relative to the support bracket. The support bracket may further be configured to be installed into an interior space of a refrigerator such that the rotatable shelf assembly is oriented in a substantially horizontal direction. A user may then place items onto the ...

The refrigerator of claim 1 wherein the at least one door shelf further comprises: an inflection point, wherein the inflection point is adjacent to both the substantially circular central section and the distal end section, and wherein the inflection point is defined by the point at which the first arc is tangent to the second arc. 3. The refrigerator of claim 2 wherein the at least one door shelf is further configured to allow for a clearance between the distal end section and the at least one rotatable shelf when the door is being opened. 4. The refrigerator of claim 3 wherein the at least one door shelf is further configured to accommodate a standard one-gallon milk jug in at least one end of the at least one door shelf and is further configured to accommodate a carton for at least one-dozen eggs in which the carton is located substantially in a central portion of the at least one door shelf. 5. The refrigerator of claim 2 wherein the distance between the first arc and the center of the at least one rotatable shelf is equal to the radius of the at least one rotatable shelf. 6. The refrigerator of claim 2 wherein the distance between the first arc and the center of the at least one rotatable shelf is greater than the radius of the at least one rotatable shelf. 7. The refrigerator of claim 2 wherein the second arc is a fractional part of less than ⅕th of the circumference that is defined by the radius with a beginning point which is concentric with the door hinge point that is positioned nearer to the distal end section than any other door hinge point of the door. 8. The refrigerator of claim 1, wherein the at least one rotatable shelf further comprises a plurality of rotatable shelves disposed within the interior space of the refrigerator, wherein the plurality of rotatable shelves that are not mechanically coupled to the at least one motor of claim 1 are individually and mechanically coupled to at least one motor, wherein the at least one motor of claim 1 and the at least one motor are configured to be independently operable and are further configured to actuate an independent rotation of at least one but not all of the plurality of rotatable shelves. 9. The refrigerator of claim 1, wherein the at least one motor is configured to automatically rotate the at least one rotatable shelf when a compressor of the refrigerator is operated. 10. The refrigerator of claim 1 further comprising a support bracket detachably coupled to the at least one rotatable shelf, the support bracket comprising: an inner surface;an upper surface;a lower surface; andan outer edge portion configured to physically engage at least one inner wall of the refrigerator, the outer edge portion being further configured to orient the upper surface of the support bracket in a substantially horizontally direction within the refrigerator, and the lower surface of the support bracket being detachably engaged with at least three bearings of a bearing ring. 11.
