Abstract: The invention relates to a pressure cooker with a container that can be airtightly closed with the aid of a cover, which can be placed upon a container edge and locked with it. A closing mechanism is provided on the cover. The closing mechanism includes a total of four arcuate closure members, acting distributively over the periphery of the cover and pivoted on the periphery of the cover. The closing mechanism can be moved by an actuating device from an open position, in which the cover can be removed from the container, into a locked position to extend underneath the container edge. In the locked position, the cover is pressed at its periphery against the container edge by interspacing an encircling ring. The total (for example four) closure members are combined into (for example two) groups of two closure members each of which are connected with hinges.

Abstract: The invention relates to a process for equipping a kitchenware object, for example a pan, a pot, roasters or the like, comprising metal, for example aluminum, an aluminum alloy, magnesium or a magnesium alloy, with an anti-adhesion coating in the stressed surface regions, for example, on the inside, in which onto the metal surface of the object, for example after roughening, a mechanically-resistant layer, such as a mechanically-resistant anodization layer or similar mechanically-resistant layer is provided, and subsequently the stressed surface regions are provided with the anti-adhesion layer, wherein, before providing the mechanically-resistant layer, a durable surface layer is applied onto the surface regions, not to be provided with the coating system (mechanically-resistant layer or the like with or without anti-adhesion layer), of the object.

Abstract: A cooking and/or boiling utensil for bottom thermal energy application through thermal conduction or through electromagnetic induction. The container has a round horizontal section of austenitic steel, a thermal distribution plate of suitable thickness flush against the container base of a metal with a good thermal conductivity, and a ferromagnetic plate cover against the thermal distribution plate. The ferromagnetic metal plate cover has cover recesses mainly formed as radial slots. The radial slots start at the center and end inwardly of the cover collar. The sandwich unit consisting of the container base, the thermal distribution plate and the plate cover is substantially deformation-proof due to adjustment of the container thickness of the container base and the container thickness of the plate cover on one hand and the length and width of the slots and the diameter of the center on the other, during thermal energy application through thermal expansion.

Abstract: A pressure cooker includes a container intended to hold cooking produce and which can be closed pressure tight with a cover that can be set on a rim of the container and locked thereto. The cover includes closing members movable between radially inward open positions, whereat the cover can be removed from the container, and radially outward locking positions, whereat the circumference of the cover is pressed against a region of the container rim with a circumferential sealing ring therebetween. The inside of the wall of the container in the region of the container rim includes a locking shoulder directed, for example, toward the container bottom, and a sealing shoulder directed, for example, toward the container opening. In the radially outward locking positions, the closing members are braced against the locking shoulder, thus pressing the sealing ring against the sealing shoulder.

Abstract: A cooking vessel includes a vessel body having a spill rim extending outwardly and bent around the vessel body. A vessel handle is attached to a wall of the vessel body. A cover than can be set closingly on the spill rim has at least one cover handle. The vessel body and the cover form a spill and ventilation appliance. To guarantee a defined venting and a simple, more reliable, and also defined pouring with more reliable handling, the wall of the vessel body in at least one peripheral region of its upper rim has a larger slope than in remaining peripheral region of the rim due to shortening the spill rim. A rim of the cover in at least one peripheral segment has at least one arch projecting in a radial direction slope when correspondingly positioning the cover through rotation. The remaining peripheral region of the vessel wall without the larger slope has a circumferential length that is at least as large as the peripheral segment of the cover having the at least one arch.

Abstract: A cooking utensil for use on both gas, electric and induction stoves is provided composed of a container liner of stainless steel with a comparatively low wall thickness, a comparatively thick bottom plate of aluminum or a metal of similarly good heat-conducting properties and a bottom disc that is at least partially composed of magnetizable material disposed on the outside of the bottom plate. The bottom plate disposed on the outside bottom of the container and possibly the bottom disc disposed on the outside of the bottom plate can be attached by a commonly known hammer-press technique at an increased temperature preferably with an intermediate foil of aluminum or a material of similarly good heat-conducting properties. Particularly favorable results for cookware in terms of expansion reaction and corrosion have been achieved utilizing a bottom disc of a nickel alloy having the following composition: Ni: 50-100%; Cr: up to 6%; Mo: up to 6%; Cu: up to 14%; Mn: up to 6%; Si: up to 1.5%; C: up to 0.

Abstract: A control device for controlling the heating capacity of the heating element of a cooking or heating plate, on which a cooking vessel, roasting vessel, or the like, can be placed and heated. The temperature on or in the cooking vessel is determined by means of a temperature sensor, conveyed to a logic circuit, and used in this for the control of the heating element by means of an output stage in dependence on the actual temperature determined and/or the temperature increase in the heating phase. In order for control of the heating output of the heating element to also be performed during a roasting process with a roasting pan placed on the cooking or heating plate, a program selection switch provided to select between various cooking processes, such as rapid simmering, steaming, warming and the like has a coordinated switching position for each and for a roasting process has an additional switching position.
