Abstract

A glass ceramic cooktop includes at least one burner delimited in a radial direction by an inner wall of insulation, and a heating element disposed under the burner for heating up a cooking pot placed on the burner. A monitoring element is provided for limiting a heating temperature to a maximum value and to limit heat generated underneath the glass ceramic surface so as to limit heat radiated on the glass ceramic surface to a predefined value. A temperature switch is disposed underneath the glass ceramic surface outside of the burner in the radial direction. The temperature switch is configured to sense radially radiating heat released outside of the burner and, within a range of from about 130° C. to about 200° C., switch off the heating element.

Claims

1. A glass ceramic cooktop comprising:

at least one burner delimited in a radial direction by an inner wall of insulation;

a heating element disposed under the at least one burner and configured to heat up a cooking pot placed on the burner;

a monitoring element configured to limit a heating temperature to a maximum value and to limit heat generated underneath the glass ceramic surface so as to limit heat radiated on the glass ceramic surface to a predefined value; and

a temperature switch disposed underneath the glass ceramic surface outside of the burner in the radial direction, the temperature switch being configured to sense radially radiating heat released outside of the burner and, within a range of from about 130°

C. to about 200°

C., switch off the heating element.

2. The glass ceramic cooktop as recited in claim 1 wherein the monitoring element is configured to limit the heat generated underneath the glass ceramic surface to a temperature of from about 800°

C. to about 900°

C.

3. The glass ceramic cooktop as recited in claim 1 wherein the temperature switch is attached directly to the glass ceramic surface.

4. The glass ceramic cooktop as recited in claim 2 wherein the temperature switch is attached directly to the glass ceramic surface.

5. The glass ceramic cooktop as recited in claim 1 wherein the temperature switch includes a wave washer thermostat.

6. The glass ceramic cooktop as recited in claim 2 wherein the temperature switch includes a wave washer thermostat.

7. The glass ceramic cooktop as recited in claim 3 wherein the temperature switch includes a wave washer thermostat.

8. The glass ceramic cooktop as recited in claim 4 wherein the temperature switch includes a wave washer thermostat.
