摘要：
Provided are a refrigerator and a fault detecting method for an ultrasound-assisted processing device thereof. The ultrasound-assisted processing device includes multiple first ultrasonic transducers set in parallel, the multiple first ultrasonic transducers are used for receiving driving signals sent by a same ultrasonic generator, and generating ultrasonic vibrations for targeted food materials; and a second ultrasonic transducer for generating actual induced voltage from the ultrasonic vibrations; the fault detecting method includes: obtaining the actual induced voltage produced by the second ultrasonic transducer; comparing the actual induced voltage with a standard induced voltage; if the actual induced voltage is less than a standard induced voltage, disconnecting the power supply of the ultrasonic generator. Thus can timely determine whether there are faults in the multiple first ultrasonic generators, so that timely maintenance or replacement can be carried out on the faulty first ultrasonic transducer to avoid danger.
