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.

A laundry dryer performs a method for drying laundry with steam or hot air and notifying a user of water shortage. The laundry dryer includes a cabinet, a drum, a steam unit, a storage tank, a supply pump, and a steam controller. The steam controller operates the steam unit upon receiving a steam supply command to supply steam to the drum. When a water level of water stored in at least one of the steam unit or the storage tank is equal to or less than a predetermined water level, the steam controller provides a water shortage notification message for user recognition. The laundry dryer provides the water shortage notification message when a minimum amount of residual water is stored in the storage tank. The number of times to refill the storage tank can be minimized, resulting in an increase in user convenience.

A combination washer/dryer appliance may include a cabinet, a tub, a laundry basket, a heater, and a controller. The laundry basket may be rotatably mounted within the tub and define a chamber for receipt of articles for washing or drying. The controller may be operably coupled to the heater and configured to initiate a wash/dry operation. The wash/dry operation may include initiating a wash/dry operation for articles within the laundry basket. The wash/dry operation may include a wash cycle and a dry cycle. The wash/dry operation may further include determining completion of the wash cycle and directing a tumble cycle of the laundry basket in response to determining completion of the wash cycle. The wash/dry operation may still further include determining a user drying preference during the tumble cycle of the laundry basket and adjusting the wash/dry operation based on the determined user drying preference.

A method of operating a washing machine appliance is provided. The washing machine appliance includes a wash basket rotatably mounted within a wash tub and defining a wash chamber configured for receiving of a load of articles. A camera is positioned with a view of the wash chamber. The method includes obtaining one or more images of the wash chamber with the camera, analyzing the one or more images using a machine learning image recognition process to determine that the articles are tangled, and adjusting at least one operating parameter of the washing machine appliance in response to determining that the articles are tangled.

A method of operating a dryer appliance includes activating a heating system of the dryer appliance and tracking an energy output of the heating system. The method also includes determining a load score of a load of articles to be dried in the dryer appliance based on the tracked energy output and determining a termination criterion for a dry operation of the dryer appliance based on the load score. The method further includes performing the dry operation in the dryer appliance and terminating the dry operation when the determined termination criterion is reached.

A dryer appliance and method for operation are provided, the method including measuring temperature of air for drying laundry articles; transmitting a first control signal for operating the ignition source to generate heat for heating air for drying laundry articles; measuring, over a period of time following transmission of the control signal, temperature of air for drying laundry articles; and determining an operational state of the heating system based on measuring the temperature of air, wherein the operational state includes a normal ignition state or an ignition failure state, wherein the normal ignition state corresponds to an increase in temperature of air during the period of time, and wherein the ignition failure state corresponds to a substantially unchanged temperature of air.

The washing machine includes control buttons controlling the washing machine to operate, and the washing machine is controlled to be connected/disconnected with a WiFi/to enter in a WiFi configuration mode by obtaining a trigger duration of one of the control buttons. The washing machine is controlled to be connected/disconnected with the WiFi/to enter in the WiFi configuration mode through the trigger duration of the control buttons, which realizes connection controllability of the washing machine and the WiFi, a user can control whether the washing machine is connected with the WiFi and enters in the WiFi configuration mode to configure a connection of the washing machine and the WiFi according to his/her own needs, which avoids conditions that the washing machine is directly connected with the WiFi and the user controls the washing machine mistakenly, and the safety of remote control of the washing machine is improved.

A laundry dryer control method comprising: setting the dryer to a default drying operation; performing the default drying operation when a user selects the default setting and does not select a dry boost setting; and performing a non-default drying operation when a user selects the default setting and does select a dry boost setting. In default operation, the dryer operates the drum and fan, and operates supplemental drying mechanism according to a predetermined schedule of on cycles and off cycles. If dry boost is selected, or if another non-default cycle is selected, the dryer operates the drum, fan and supplemental drying mechanism using a temperature feedback control loop, and operates until the laundry reaches a first dryness threshold.

A method for operating a washing machine appliance may include a step of activating a wash cycle of the washing machine appliance. The method may also include a step of flowing a fill of liquid water to a tub of the washing machine appliance. The method may further include a step of flowing a wash substance to the tub of the washing machine appliance. The method may also include a step of monitoring conductivity measurements and turbidity measurements of the tub. The method may further include a step of determining a classification of the wash substance flowed to the tub of the washing machine appliance. The method may also include a step of comparing the determined classification of the wash substance to a selected classification of the wash substance.
