| 摘要 |
The present invention relates to a cooking range (1) comprising an upper panel (2) preferably produced of glass or ceramic, at least one heater (3) arranged underneath the upper panel (2), a lower panel (4) preferably made of sheet metal disposed below the upper panel (2) for defining a closed volume wherein the heater (3), electrical and mechanical elements and the connections are contained, and one or more springs (5) secured on the lower panel (4) connected to the heater (3) so that the heater (3) abuts against the upper panel (2) for maintaining a full surface contact. Supports (6) of shape memory alloy are secured on the lower panel (4) in regions that might be deformed with the effect of heat during operation of the heaters (3). Thereby the lower panel (4) is strengthened against deformation due to heat. |
