| 摘要 |
The diagnostic system (120) of the present invention monitors and accumulates the thermal signatures or characteristics during at least one operational mode of the cooking appliance (105). These thermal signatures or characteristics are collected - through the same temperature sensor (115) used to regulate the temperature of the cooking appliance (105) - and then stored in, for example, a look-up table. Advantageously, this may be accomplished without the need of special sensors or interface boards. The thermal signatures or characteristics may include first order or higher order temperature gradients, as well as temperature profiles. The stored thermal signatures provide a baseline from which the diagnostic system can detect and identify whether the cooking appliance is working under normal operating conditions.
