  • the invention relates to a lid for a pressure cooker.
  • the invention relates to a lid for pressure cookers with a pouring edge, which are also useful as conventional pots.
  • Pressure cookers are cooking devices that work according to the principle of boiling point elevation. Such pressure cookers are provided with a lid with a pressure relief valve over which the desired working pressure of the pot is set. So food can be cooked at temperatures of usually about 120 ° C in a much shorter time.
  • Pressure cookers are designed as pressure vessels and must meet high safety requirements.
  • Conventional pressure cookers usually include a pot which is provided with circumferential grooves or the like, in which a matched lid can be locked.
  • Pressure cookers are due to the existing on the pot locking means usually little suitable to be used as a normal cooking pot for pressureless cooking.
  • the European patent specification EP 1 416 837 therefore proposes a lid for a pressure cooker having U-shaped bent claws, by means of which the lid can be locked on the pouring rim of a "normal" shaped pot.
  • This bowl provided with a pouring rim is much better suited
  • the disadvantage here is that the entire cover of the pot must be exchanged for normal, unpressurized use, although the locking claws can be removed for cleaning according to the teachings of the above-mentioned document, but this is relatively complicated since this requires a nut to be loosened on the underside of the lid, this usually requires a tool, and the clawed lid is poorly suited for being used as a normal cooking pot lid when unlatched, and is therefore required , for pressureless operation of the cooking pot a second lid in stock z Furthermore, the structure of the lid is relatively complicated and complicated.
  • the German utility model DE 20 2009 015 975 discloses a cooking vessel and a cooking vessel system kit - especially a cooking vessel for all types and types of energy / types of stoves and different cooking temperatures and pressures, pressure and pressure, self or externally heated, preferably a steam pressure cooker ago - with a container for receiving cooking material and with a pressure-tight and on this with various methods lockable function lid and the relevant regulations corresponding pressure relief valve technology and other comfort functions, the cooking vessel consists of a cover module and a pot module that the cover module consists of the function cover with seal and pot edge with cold handles and the pot module has a system network with a mechanical, fixed and sealed interface.
  • the structure of the cooking vessel consists of the lid module with thejansdek- angle, which is releasably connected to the pot lid via a fastening nut or release screw, and this combination by means of a lid lock sealingly connected to the pot edge, which forms the interface to the pot module.
  • a steam pressure cooker is presented with a lid module consisting of a container and a lid which is intended to be placed on the container and locked to form a tight cooking closure, one or more Jaw for locking the lid on the container and means for driving the at least one jaw between a locked and unlocked position, wherein there is at least one module intended to be mounted on and detachably attached to the lid; the module at least on the one hand comprises a control device of the cover locking / unlocking of the container and, on the other hand, at least one of the following elements, such as a minute counter, a pressure regulating valve, a pressure sensor, a temperature sensor, an overpressure safety valve, a closing / opening securing means or a bistable steering means.
  • the mechanical-electro-mechanical interface between handle module and closure device / lid is arranged;
  • the handle module contains the mechanical and sensory control of the pot and thus most contacts with the closure device and the lid.
  • the handle module is water-sensitive.
  • the invention is based on the object to provide a lid for a pressure cooker, whose handling is improved.
  • the invention relates firstly to a lid for a pressure cooker, in particular a lid, which can be locked on conventional pots with a pouring rim.
  • the lid comprises an upper and a lower lid module; the upper cover module consists of a closure unit and a locking device and is closed by a center plate against the lower cover module.
  • the lower cover module includes a Zarberckel with seal and a valve assembly. Under a Zargendeckel a lower lid is understood with a circumferential ridge or a frame, which has a seal and which is inserted into the pot.
  • the lid comprises a closure unit, which is usually formed with a knob and by means of which the lid can be lifted off the pot. To create a pressure-tight container, the lid is lockable on the cooking pot.
  • the closure unit has means for lifting it from the frame cover together with at least the part of a locking device.
  • the cover thus comprises virtually two modules, namely a lower cover module with a Zargendeckel and a valve assembly and an upper cover module with a closure unit, a locking device and a center plate.
  • a separation of the upper lid module can be performed in a very simple manner, without having to be solved for example on the lower cover module nuts or screws.
  • the Zargendeckel has means to which the closure unit can be attached. After removing the closure unit with the locking device and the center plate - so the upper cover module - this module part can be replaced by a conventional handle assembly without locking mechanism. Thus, from the Zargendeckel together with this other handle a normal lid, which is well suited for conventional, non-pressure or low pressure cooking. Because of this simple interchangeability, the user does not need to keep two different covers, namely a lid for quick cooking and a lid for unpressurized or low-pressure cooking, in stock.
  • the cleaning of the lid is facilitated by the fact that the mechanism for removing the closure unit and the locking device is arranged in the upper cover module on top of the lid.
  • An actuation of, for example, a screw on the underside of the lid usually complicates the cleaning, since the bottom can be soiled after cooking by food residues.
  • the closure unit can be fastened to a preferably centrally attached to the Zargendeckel valve.
  • the valve housing which is for example formed as a hollow cylinder, can be used to attach a closure unit thereto.
  • the closure unit need not be secured by a separate threaded bolt or the like and attached to the Zargendeckel valve does not interfere with the use of Zargendeckels as a normal lid for unpressurized or low pressure cooking, but is designed as a receptacle for the further handle assembly.
  • At least one valve in the Zargendeckel arranged, the valve hollow cylinder is used for fastening the closure unit or a handle assembly.
  • This valve is used in one embodiment of the invention for determining the working pressure of the pot. This means that the valve arranged in the Zargendeckel opens at the desired working pressure and thus regulates the temperature of the boiling point of the water, which prevails inside the pot.
  • a safety valve which is provided as a second valve which opens at higher pressure, if the other valve fails and / or which at Pressure locks the locking device of the lid, so that it can not be opened manually.

  • the upper lid module is to be separated from the lower lid module via a slide mechanism.
  • a slide mechanism comprises a slide which is positively connected in one position, for example with the collar of a fastening bolt of a hollow-cylinder-shaped valve housing. About an offset of the slider, this shifts into a position in which the positive connection is released. In this way, the upper cover module can be very easily removed by pressure on the handle of the slider and separated from the lower cover module.

In the locked state is thereby achieved that when pressure builds an inwardly directed force is exerted on the claws. An unlocking is therefore only with great effort or - especially at higher pressure - not possible.
  • the pot preferably comprises two valves, namely a valve for determining the working pressure and a safety valve which blocks, for example, the locking device under pressure, so that the pot can not be opened.
