摘要： The present invention utilizes a self-contained control module consisting of the electronics necessary to the control the various operations of the cooking appliance in which the module is installed, preferably including the high voltage control electronics. The control module is easily accessible and removable from the front panel without the risk of exposure to high voltage due to the presence of a safety interlock that automatically cuts the high voltage to the control module and, if desired, to other subassemblies the instant the control module is removed. In addition, the control module is housed within an electrically conductive liner to control EMI emissions. Once the control module is removed, the interior of the appliance is sufficiently sealed off by a perforated cage to prevent further access to power lines or any high voltage circuits interior to the appliance which may have not been wired through the safety interlock. Moreover, to ensure that a faulty control module is replaced properly, coded connectors, such as keyed connectors, are used between the control module and other subassemblies of the appliance, such as temperature sensors, high voltage circuits and power supplies, and low voltage circuits that may reside in the interior of the appliance.

摘要翻译： 本发明利用一个独立的控制模块，该控制模块由控制模块安装的烹饪器具的各种操作所需的电子装置组成，优选地包括高压控制电子装置。 由于存在自动切断控制模块的高电压的安全联锁，并且如果需要的话，控制模块可以从前面板轻松访问和拆卸，而不会暴露于高电压的风险，即时控制 模块被删除。 此外，控制模块容纳在导电衬垫内以控制EMI发射。 一旦控制模块被移除，器具的内部就被穿孔的笼子充分地密封，以防止进一步接近电线或设备内部的任何高压电路，这些线路可能尚未通过安全互锁线连接。 此外，为了确保正确更换故障控制模块，在控制模块和设备的其他子组件之间使用诸如键控连接器之类的编码连接器，例如温度传感器，高压电路和电源，以及低压电路 这可能驻留在设备的内部。
