Embodiment Construction

[0031] figure 1 A hob is schematically shown with a heating zone 10 consisting of two concentric heating elements 12a and 12b. A cooking vessel 20 is placed on a glass or glass ceramic cooktop (not shown). The cooker's control unit 18 detects the diameter D of a cooking vessel 20, such as a pot or a pan, and switches on the radially outer heating element 12b of the heating zone when the diameter D of the cooking vessel 20 exceeds a predetermined threshold. In an alternative embodiment of the invention, the user can manually switch on the radially outer heating element 12 b via the user interface 22 as required.

[0032] figure 1The hob shown is in the form of an induction hob and the heating elements 12a, 12b are inductors, which are supplied by current supply units 14a, 14b in the form of inverters. The circuit comprising one of the heating elements 12 a , 12 b and one of the inverters 14 a , 14 b in each case can be switched on or off via a switching unit 16 . The switch...

Abstract

A cooktop is provided that includes heating elements which are combined to a heating zone; a power supply to generate a heating current that operates the heating elements; a switch to open and close a power circuit that includes the power supply and one of the heating elements; and a controller that determines a characteristic variable of the heating current, actuates the switch as a function of a selected power level to operate the heating zone, and activates, in a first operating state, two of the heating elements, which are combined to form the heating zone, in different phases of a heating period.

Description

technical field [0001] The invention relates to a hob and a method of operating such a hob. Background technique [0002] The prior art discloses cookers comprising a plurality of heating elements forming a heating zone. These heating elements can, for example, be arranged concentrically and be operated in such a way that the outer ring of the heating zone is only activated when the diameter of the pan placed on the heating zone exceeds a limit value. In another known cooker, a plurality of heating elements are arranged in an array or grid, such as a 4x4, 6x6 or 8x8 grid. The cooking utensils placed on the hob are detected and a plurality of heating elements arranged under the cooking utensils are combined to form a freely configurable heating zone. [0003] A plurality of heating elements forming a heating zone are respectively supplied with heating current by a current supply unit. Especially if the heating elements are induction heating elements or inductors, each indu...
