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.

Abstract: The invention involves a method for measuring the temperature in a heating system of the type having an electrically heated hot plate with a filled cooking vessel on it and a radiation pick-up located at varying distances from the side of the vessel and pointed at it which emits a signal indicating the temperature of the substance in the vessel based upon radiation from an area on the side of the vessel as detected by the radiation measurement field of the radiation pick-up, the radiation intensity of which decreases as a square of increasing distance. To compensate for the effect on measurements of spurious radiation form the changing position of the vessel on the hot plate, the invention involves adjusting the angle of a non-intersecting radiation measurement field to obtain corresponding reduction in the area of radiation detetion on the vesel for increasing distances between vessel and radiation pick-up.

Abstract: A device for determining the temperature of a glass ceramic plate heated using heat coils or halogen lamps with a temperature sensor which emits a signal for a control circuit corresponding to the temperature of the glass ceramic plate. The heat coils or the halogen lamps are positioned in the internal space of a cylindrical vessel-like insulation support, and in which the surrounding wall of the insulation body, under spring tension, abuts on the glass ceramic plate heated by the radiation of the heating coils or the halogen lamps. Adequate control precision can be achieved by having the temperature sensor positioned in a recess in the surrounding wall of the insulation body, and is in a thermally-conductive connection with the lower side of the glass ceramic plate. The recess for the temperature sensor is positioned at a distance to the internal space of the insulation support and thus the dynamics of the control behavior can be adjusted to low hysteresis and optimized.

Abstract: The invention relates to controlling the simmering or cooking time in a cooking vessel which can be heated by means of an electrical cooking plate with a control circuit, in which the temperature in or on the cooking vessel is determined in the heating phase and utilized by the control circuit to regulate the heat output of the cooking plate by shutting off the cooking plate at a length of time before the completion of the predetermined simmering or cooking time, the time before completion being greater the greater the heat quantity determined from data from the heating phase.

Abstract: This invention relates to controlling the simmering or cooking time in a cooking vessel which can be heated by means of an electrical cooking plate with a control circuit, in which the temperature in or on the cooking vessel is determined and utilized by the control circuit to regulate the heat output of the cooking plate, in which the simmering or cooking time can be set by means of an adjustable time element, in which the cooking plate can be shut off at a length of time bvefore the completion of the predetermined simmering or cooking time which is greater the slower that the rise of the temperature in the heating phase is, and in which, by using the heat content contained inthe cooking material after shutting off the cooking plate the simmering or cooking process is extended up to the preset simmering or cooking time.

Abstract: A process and apparatus for cooking food in a roasting vessel, in which the temperature in and around the roasting vessel is measured and used to regulate the cooking temperature according to a preset program by means of a control circuit which activates and deactivates an electric heating element. By controlling the heat output according to a preset program, whereby the program is effected when a predetermined temperature differential from the preset roasting temperature is reached, the cooking temperature can be controlled without overshooting the preset roasting temperature, even during high rates of temperature increase which occur during the heating cycle of the roasting operation.

Abstract: A frying pan is disclosed comprising an upward-facing pan border surrounding a pan bottom to define a pan body, the pan bottom including an upper side to provide a frying surface and a bottom side to provide a stand surface. At least one depositing surface is disposed inside the pan border adjacent to the pan border, with the depositing surface being smaller in area than the frying surface. The depositing surface is raised with respect to the frying surface and spaced, in plan view, outside of the stand surface, with connecting means disposed between the depositing surface and the frying surface which connecting means includes a step.

Abstract: The invention relates to a new-type, easy-to-clean pan of compact, attractive form with divided useful surface, namely a frying surface and a depositing surface, which are distinguished from one another by a temperature gradient.
