A control is provided for switching on and off two heating devices of a hob forming a hotplate. In cyclic manner the continuous energy or power generation level can be adjusted by an energy control device. A temperature limiter monitors a maximum temperature via the first heating device, but not via the second heating device. The energy control device controls the first heating device directly or switches the same. The temperature limiter trips a power relay in order to switch the second heating device simultaneously with the first heating device.

Device for switching on and off several heating mechanisms of cooking equipment as well as cooking equipment with such a device

An appliance for a hotplate has two heating devices installed parallel to one another. With an energy control device and as a function of an angular position, either a first heating device is operated in controlled manner or a second heating device is connected thereto in fixed form. The power of the second heating device is defined so low that no temperature limiter for protecting a glass ceramic plate has to be provided in the control path of the second heating device. On connecting in the second heating device, the controlled power of the first heating device is lowered to an initial value by roughly the amount of the power of the second heating device. The total power results from the summated power of the two heating devices.

An electric radiant heater ( ) is provided having an active sensor ( ) for detecting the position of a cooking vessel on a glass ceramic plate over the radiant heater ( ). The sensor ( ) is mad from electrically conductive material and is part of an inductive resonant circuit of a control operating by resonant circuit detuning. It also covers a heating zone ( ) of the radiant heater ( ). The sensor ( ) runs substantially linearly and, unlike conventional sensor coils, has a loopless construction. It is e.g. possible to stretch a wire ( ) or also to use the tube ( ) of a rod regulator.

A shaped thermal insulation body comprises inorganic material. The shaped body has the following, weight-related composition: approx. 20 wt. % inorganic filling material: approx. 40 wt. % opacifier; approx. 10 wt. % fibrous material; and approx. 15 wt. % hardening agent as well as approx. 15 wt. % water. The shaped body only contains a small amount of fumed silica with a comparatively small BET surface. Water glass is excluded during its manufacture. It can be used as a spacer for radiant heaters.
