Abstract: A laundry treatment appliance includes a cabinet; a drum rotatably mounted within the cabinet; a sealed system; a duct system; a blower fan capable of operating at variable rotational speeds; and a controller configured to perform an operation. The operation includes directing the blower fan at a preliminary rotational speed; determining a condensation capacity of the sealed system with regards to the process air in the duct system; determining a mass flow rate of moisture in the process air while directing the blower fan at the preliminary rotational speed; determining a target rotational speed of the blower fan corresponding to a set ratio of the determined condensation capacity to the determined mass flow rate; and directing the blower fan at the determined target rotational speed.

Abstract: Dryer appliances and related methods are disclosed. Such methods may include, or such appliances may be configured for, monitoring a temperature with a thermistor of a primary heat control system of the dryer appliance. The present disclosure also includes determining a relay signal is calling to close a relay and thereby activate a heating system of the dryer appliance and verifying that the relay is closed. The present disclosure further includes allowing a minimum relay on time to elapse after verifying that the relay is closed. The present disclosure also includes determining a temperature gradient of the monitored temperature based on a change in the monitored temperature over the minimum relay on time. The present disclosure further includes detecting a nuisance trip because the determined temperature gradient is negative.

Abstract: A laundry appliance uses a determination of a frequency of compressor temperature response, refrigerant mass flow rate, or both to determine accumulation of lint in a filter. Based on the determination, various corrective actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof.

Abstract: A dryer appliance and steam generation system is provided. The dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber for receipt of articles for drying. The drum includes a plurality of openings allowing fluid communication into the chamber. An induction heating element is positioned on a non-ferrous substrate. The non-ferrous substrate is positioned between the induction heating element and a ferrous substrate. The ferrous substrate is positioned in an interior volume, and a nozzle is positioned in the interior volume to eject water onto the ferrous substrate. The induction heating element is positioned fluidly separate from the water ejected from the nozzle.

Abstract: A laundry appliance uses a determination of volumetric airflow rate after a steady state condition is reached to determine the accumulation of lint in filter. Based on the determination, various actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof. One or more temperature sensors, relative humidity sensors, and weight sensors are used to provide measurements for determining the volumetric airflow rate.

Abstract: Dryer appliances, including methods of operation, are provided herein. The dryer appliance may include a cabinet, a drum, a ventilation assembly, an air handler, and a controller. The drum may be rotatably mounted within the cabinet. The drum may define a drying chamber. A ventilation assembly may be attached to the drying chamber. The ventilation assembly may include a conduit defining an exhaust passage in fluid communication with the drying chamber. The conduit may extend from an inlet at the drying chamber to an outlet defined through the cabinet. The air handler may be attached to the conduit in fluid communication with the drying chamber to draw air through the exhaust passage. The controller may be in operable communication with the air handler and the drum, and may be configured to initiate a dry cycle.

Abstract: 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.
