摘要： A compressor frequency regulation method includes acquiring a first exhaust temperature of a compressor operating at a first operating frequency; determining that the first exhaust temperature is greater than or equal to a first preset temperature; controlling the compressor to perform frequency reduction processing, the frequency reduction processing reducing the first operating frequency to a second operating frequency, such that a second exhaust temperature of the compressor operating at the second operating frequency is less than the first preset temperature; and controlling the compressor to operate at the second operating frequency.

摘要： A dryer is provided. The dryer includes a cabinet, a drum rotatably disposed inside the cabinet, at least one roller mounted on at least one surface inside of the cabinet to support the drum, a motor configured to provide power to rotate the drum, a motor driver configured to control the motor, and at least one processor configured to determine at least one of a first rotation velocity of the motor or a first rotation time of the motor based on a non-use time of the dryer, and control the motor driver based on the determined at least one of the first rotation velocity or the first rotation time of the motor.

摘要： A clothes dryer includes a housing, a fan, and a sound blocker. The housing defines an internal cavity and an orifice. The fan is configured to direct air through the internal cavity. The sound blocker is disposed within the cavity and is configured to unwind and wind between a first position and a second position, respectively. In the first position, the sound blocker is unwound and disposed over the orifice to obstruct fluid communication between the internal cavity and an exterior of the housing via the orifice and to reduce noise emitted through the orifice. In the second position the sound blocker is wound and retracted away from the orifice to allow fluid communication between the internal cavity and the exterior of the housing via the orifice.

摘要： A clothes dryer includes a housing, a fan, and a sound blocker. The housing defines an internal cavity and an orifice. The fan is configured to direct air through the internal cavity. The sound blocker is disposed within the cavity and is configured to linearly slide between a first position and a second position. In the first position, the sound blocker is disposed over the orifice to obstruct fluid communication between the internal cavity and the exterior of the cabinet via the orifice, and to reduce noise emitted through the orifice. In the second position, the sound blocker is retracted away from the orifice to allow fluid communication between the internal cavity and the exterior of the cabinet via the orifice.

摘要： A dryer appliance includes a microphone for monitoring sound generated during operation of the dryer appliance and a controller is operably coupled to the microphone. The controller is configured for obtaining a sound signal generated during operation of the dryer appliance and converting the sound signal into a spectrogram that represents a sound frequency and a sound amplitude over time. An artificial intelligence image recognition process is used to analyze the spectrogram to identify one or more sound signatures that are associated with particular operating conditions, and operation of the dryer appliance is adjusted based at least in part on the identification of the sound signature.
