    • Various embodiments are directed to systems and methods for controlling a vent fan motor associated with a dishwasher based at least in part on sensed vibration signals. A vibration sensor, such as a microphone and/or an accelerometer, may be associated with the vent fan motor and may be configured to sense sound pressure level vibrations emitted by the vent fan motor. A controller associated with the dishwasher may receive the sensed vibration signals, identify various operating characteristics of the vent fan motor, and may compare the identified operating characteristics against preferred operating characteristics. A determination that the operating characteristics do not satisfy the preferred operating characteristics may correspond to inefficient operation of the vent fan motor, and the controller may thus adjust the vent fan motor speed.
    • 各种实施例涉及用于至少部分地基于感测到的振动信号来控制与洗碗机相关联的排气扇电动机的系统和方法。 诸如麦克风和/或加速度计的振动传感器可以与通风扇马达相关联,并且可以被配置成感测由通风扇马达发出的声压级振动。 与洗碗机相关联的控制器可以接收感测到的振动信号,识别通风扇电动机的各种操作特性,并且可以将识别的操作特性与优选的操作特性进行比较。 操作特性不满足优选操作特性的判断可能对应于通风扇马达的低效率操作,并且控制器因此可以调节通风扇马达的速度。
