    • A domestic appliance, shown in the form of a refrigerator, includes a cabinet within which is defined at least one compartment. A controller is mounted to the appliance for controlling various operating parameters of the appliance. The controller also includes a memory having stored therein a plurality of operating parameters associated with a plurality of appliance models. The appliance has an identification element affixed thereto and a communication device that is operatively connected to the controller. The communication device receives signals that provide programming instructions to the controller to activate particular ones of the plurality of operating parameters associated with the respective appliance model. In this manner, a universal controller can be employed in any one of a wide range of appliance models.
    • 以冰箱形式示出的家用电器包括一个橱柜,在其中限定了至少一个隔间。 控制器被安装到设备上,用于控制设备的各种操作参数。 控制器还包括存储器,其中存储有与多个设备模型相关联的多个操作参数。 该设备具有附着于其上的识别元件和可操作地连接到控制器的通信设备。 通信设备接收向控制器提供编程指令的信号,以激活与相应的设备模型相关联的多个操作参数中的特定操作参数。 以这种方式,通用控制器可以用于广泛的器具型号中的任何一种。

    • A control system for a refrigerator ice/water dispenser includes an actuation switch, at least one drive unit for releasing either ice or water, a motor activation relay that controls operation of the drive unit, and a power system having multiple power supplies for operating the control system, motor activation relay and drive unit(s). Preferably, the dispenser includes multiple actuation switches, e.g. a water activation switch and a water/ice activation switch, each having an associated activation relay for independently controlling the release of water and/or ice respectively. Current for initiating the drive unit activation relays must pass through a corresponding actuation switch in order to prevent unintended release of water and/or ice. Multiple processor circuits are preferably employed, with one processor circuit relaying to another processor circuit to enable drive unit activation. Preferably, the actuation switches constitute membrane switches so as to maintain minimum voltage levels at the dispenser.
    • 一种用于冰箱冰/水分配器的控制系统,包括致动开关,用于释放冰或水的至少一个驱动单元,控制驱动单元的运行的马达启动继电器,以及具有多个电源的电力系统, 控制系统,电机启动继电器和驱动单元。 优选地,分配器包括多个致动开关,例如。 水激活开关和水/冰激活开关,每个具有相关联的激活继电器,用于分别独立地控制水和/或冰的释放。 用于启动驱动单元激活继电器的电流必须通过相应的致动开关,以防止水和/或冰的意外释放。 优选地采用多处理器电路,其中一个处理器电路中继到另一个处理器电路以使得驱动单元激活。 优选地,致动开关构成膜开关,以便在分配器处保持最小电压电平。
