Embodiment Construction

[0041] figure 1 A sectional view of a cooking device 1 according to the invention is shown with a wok 10 on the cooking device 1 .

[0042] The cooking surface 2 on top of the cooking device 1 is concavely curved and thus adapts to the convexly curved lower surface 20 of a wok 10 placed on the cooking surface 2 . The cooking surface 2 is divided into a circular inner partial surface 2a, which is energized by an induction coil 3a as part of the induction element 3, and an annular outer partial surface 2b, which immediately surrounds said inner partial surface 2a, and the outer partial surface 2a. The surface 2b is powered by an induction coil 4a which is part of the induction element 4 .

[0043] image 3 A sectional view of another cooking device 12 according to the invention is shown, which can be used as a rice cooker and has a rice pot on it.

Abstract

The invention relates to a cooking device (1, 12) for a cooking container (10, 11), a) wherein the cooking device (1, 12) comprises at its lower surface (20) a curved, especially concave, cooking surface (2) adapted to the form of the cooking container (10, 11), b) wherein the cooking surface (2) comprises a first (2a) and a second (2b) partial surface, c) wherein the cooking container (10, 11) comprises a first area (20a) adjacent to the first partial surface (2a) and a second area (20b) adjacent to the second partial surface (2b), d) wherein the first area (20a) is heated by a first induction element (3) and the second area (20b) is heated by a second induction element (4), e) wherein each induction element (3, 4) comprises an individual heat sensor (3d, 4d) and f) wherein at least the second induction element (4) can be controlled independently from the first induction element (3).

Description

technical field [0001] The invention relates to a cooking device for a cooking vessel. Background technique [0002] In a relatively large number of cooking vessels, such as woks or rice cookers, heat is generated at different heights because these cooking vessels have a curved lower surface. When cooking in these containers, the amount of liquid inside often changes or decreases as liquid is added or evaporates during cooking. [0003] On the other hand, areas filled with liquid have a greater heat capacity than areas without liquid. However, this means that there is a risk of overheating the container in the liquid-free zone. However, if the heating area is reduced too much, not enough heat will reach the vessel, so that fast cooking as desired with high power is not possible for a cooking vessel (like a wok or rice cooker). Contents of the invention [0004] Thus, the object of the present invention is to provide a new cooking system which, inter alia, overcomes thes...
