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.

The invention claimed is: 1. An appliance for cooking food under pressure, the appliance comprising: a vessel and a lid for being fitted and locked on said vessel in order to form a leaktight cooking enclosure; at least one jaw for locking the lid relative to the vessel; means for driving said at least one jaw between a locking position and an unlocking position; and a module for fitting on and releasably securing to the lid, said module including a device for controlling locking and unlocking of the lid relative to the vessel. 2. The cooking appliance according to claim 1, further comprising a timer optionally removably mounted on the module. 3. The cooking appliance according to claim 2, wherein the module includes a pressure regulator valve: which is arranged within the module so as to be in leaktight communication with a regulator opening formed through the lid; which is responsive to the pressure that exists inside the cooking enclosure; and which is mounted to move between two stable abutment positions, a first position in which it closes off communication from the enclosure to the outside so long as the internal pressure is less than a predetermined pressure P1, and a second position in which it puts the inside of the enclosure into communication with the outside via a steam outlet as soon as the internal pressure reaches substantially the predetermined pressure P1. 4. The cooking appliance according to claim 3, wherein the module incorporates a pressure sensor and/or a temperature sensor. 5. The cooking appliance according to claim 4, wherein the temperature sensor is disposed in the vicinity of the steam outlet so as to sense the increase in temperature that results from steam passing through the steam outlet. 6. The cooking appliance according to claim 5, wherein the temperature sensor is functionally connected to the timer so as to cause it to be triggered as soon as the temperature rise is sensed. 7. The cooking appliance according to claim 1, wherein the module incorporates an excess pressure safety valve: which is arranged within the module so as to be in leaktight communication with a pressure relief opening formed through the lid; which is responsive to the pressure that exists inside the cooking enclosure; and which is mounted to move between two stable abutment positions, a first position in which said safety valve closes off communication from the enclosure to the outside so long as the internal pressure is below a predetermined pressure P2, and a second position in which it puts the inside of the enclosure into communication with the outside as soon as the internal pressure reaches substantially the predetermined pressure P2. 8. The cooking appliance according to claim 1, wherein the module incorporates the driving means for driving the at least one jaw. 9. The cooking appliance according to claim 1, wherein the module incorporates the at least one jaw. 10. The cooking appliance according to claim 1, wherein: the at least one jaw is mounted to be moved in translation by at least one respective drive arm between the locking position and the unlocking position; and the device for controlling locking and unlocking comprises a main control member mounted to move in translation and an intermediate transmission part positioned to turn freely relative to the main control member and to the driving means, so as to be turned by the main control member in order to engage the driving means so as to govern the displacement thereof. 11. The cooking appliance according to claim 10, wherein the module incorporates opening/closing safety means which are arranged within the module so as to be in leaktight communication with a safety opening formed through the lid, the position thereof being responsive to the pressure or the temperature that exists in the cooking enclosure, said safety means being mounted to move between two stable abutment positions, a first position in which said safety means puts the inside of the enclosure into communication with the outside below a predetermined internal pressure P3, and a second position in which it closes off communication from the enclosure to the outside when the pressure P3 is reached, in order to enable the pressure inside the appliance to rise and cooking to take place. 12. The cooking appliance according to claim 11, wherein the intermediate transmission part is shaped so as to co-operate with the safety means so that said safety means prevent the intermediate transmission part from turning and thus prevent the lid from being unlocked while the internal pressure is greater than or equal to the pressure P3, said intermediate transmission part also being shaped to prevent the safety means from reaching its position in which it closes off communication from the enclosure to the outside when said intermediate transmission part is in a position other than its position corresponding to locking. 13. The cooking appliance according to claim 11, wherein the module incorporates bistable leakage means: which are arranged within the module so as to be in leaktight communication with a leak opening formed through the lid; and which are suitable for taking up firstly an open position allowing air to leak from the inside of the cooking enclosure to the outside, and a closed position corresponding to no leakage of air to the outside. 14. The cooking appliance according to claim 13, wherein the bistable leakage means are integrated in the safety means. 15. The cooking appliance according to claim 14, wherein the bistable leakage means are integrated in a pressure gauge rod and include, as a moving shutter element, a bimetallic strip supported by said pressure gauge rod. 16. The cooking appliance according to claim 13, wherein the bistable leakage means are means for venting air from the appliance. 17. The cooking appliance according to claim 1, wherein the module is fixed to the lid by means of a screw-and-nut system that tightens progressively in co-operation with a fastening opening formed through the lid. 18. The cooking appliance according to claim 17, wherein the fastening opening is formed substantially at the center of the lid. 19. The cooking appliance according to claim 1, further comprising two jaws mounted to move radially on the lid by two respective drive arms between the locking position and the unlocking position, each of said drive arms (5) being provided with an axial guide stud, wherein the module comprises: a seat presenting an inside face and an opposite outside face, said seat providing an interface with the lid when the module is fitted on and secured to the lid, said seat comprising: an excess pressure safety valve; a pressure regulator valve provided with a user-adjustable rating system; a steam outlet duct starting downstream from the pressure regulator valve and having a temperature sensor mounted in the vicinity thereof; a one-piece assembly including air venting means integrated in a pressure gauge rod; a fixing pin extending substantially from the center of the outside face in order to secure the module releasably to the lid; an assembly pin extending substantially from the center of the inside face, and on which there is pivotally mounted a pivoting plate as an intermediate transmission part, the pivoting plate provided with two oblong drive slots disposed symmetrically about the assembly pin, said oblong drive slots co-operating with two respective rectilinear oblong slots formed radially in the seat to define two engagement openings for engaging each of said guide studs; and an opening pushbutton mounted to move radially relative to the assembly pin and including an oblong drive orifice extending obliquely relative to the radial direction and co-operating with a guide peg secured to the pivoting plate so that radial displacement of the opening pushbutton causes the pivoting plate to turn, thereby causing the engagement openings to move radially and entrain the guide studs and thus the arms and the jaws to the unlocking position; and a top cap which covers the seat and all of the elements that are mounted therewith, said top cap comprising: a housing for receiving a timer provided with at least one electrical connection tab functionally connected to the temperature sensor; and an axially movable closure pushbutton.
