Electric cooking and heating plate. Patented in the German Empire on August 5, 1925.

The previously known electric cooking and heating plates have the disadvantage that at Use of cooking appliances which have got uneven or curved floors due to uneven heating the heating surface with the bases of the cooking appliances is inadequate. As a result, the heat utilization is in the electric hotplates Significantly worse than the electric cooking appliances with built-in heating resistors. The power consumption of the Hotplates according to the previously known

performance is therefore significantly higher than the power consumption at the same performance electrical cooking appliances with built-in heating resistors. Sometimes it is, special with small hotplates, hardly possible to bring anything to the boil.

The invention eliminates these inconveniences in that the heating surface is divided and the individual parts are movable

ίο are arranged. This makes it possible Using every cookware with success and purchasing several more expensive ones avoid electric cookware.

In the drawing, twelve sector-shaped heating elements are provided, which in the usual known design consist of a metal plate, mica, heating resistor and heat-insulating substrate.
On the underside of each individual radiator (Fig. 3) there is a rest bearing a, which allows a deviation from the horizontal position on all sides. The base plate e (Fig. 1 and 2) is provided with radially arranged counter bearings α .

In order to prevent rotation around the rest bearing α , incisions b, b (Fig. 3) are provided, and the guide pins c, c that fit in these incisions hold the radiators in their radial position without hindering their horizontal movement .

The plate / and the heads g of the pins c (Fig. 2) prevent the radiators from falling down.

The radiators are connected to one another in an electrically conductive manner. The ends of the lines lead to the contact pins i (Fig. 1). The individual radiators can be switched one after the other or in parallel after being activated.

If a cooking device is placed on the heating plate, the heating surface adapts automatically due to the weight of the cookware to the bottom of the same, regardless of whether the bottom is curved flat inwards or outwards.

Appropriate arrangement can prevent boiling over. Liquids no power shortage bring about.
