Abstract: A dryer appliance, including methods of operation, is generally provided herein. At least one method may include measuring an ambient temperature of air unheated by the heater; comparing the measured ambient to a baseline ambient temperature; setting an airflow temperature threshold based on the comparison; and directing the heater based on the airflow temperature threshold.

Abstract: Dryer appliances and methods for operating dryer appliances are provided. A method includes calculating an initial cycle time, and counting down from the initial cycle time for an initial countdown time. The method further includes determining, during the step of counting down from the initial cycle time for the initial countdown time, whether a load size value and an air flow value have been established. The method further includes calculating, when the load size value and the air flow value have been established, a first updated remaining cycle time based on the load size value and the air flow value.

Abstract: A heater assembly for an appliance is provided. The heater assembly includes a housing and a thermostat. The housing defines an aperture. The thermostat includes a probe that is positioned adjacent the aperture. The aperture can increase the accuracy of temperature measurements by the thermostat and hinder unnecessary tripping of the thermostat.

Abstract: A dryer appliance is provided. The dryer appliance includes a cabinet and a drum mounted therein. The dryer appliance also includes a heating assembly. A duct extends between the heating assembly and an opening defined by a back wall of the drum. A seal is positioned at the opening of the back wall and extends between the duct and the back wall of the drum.

Abstract: A laundry dryer is provided including a dryer casing with a drum for receipt of articles for drying positioned therein. The laundry dryer also includes a heating system positioned in the dryer casing, the heating system including an evaporator configured to cool and dehumidify air from the drum and a heating element configured to heat air provided to the drum. The laundry dryer also includes features for hindering a transfer of an extreme temperature condition from the drum to the heating system.

Abstract: A drying method in a dryer machine which involves sending a pulse according to a pulse pattern formed by: energizing each of a plurality of actuators of a heater for a first determined set time; de-energizing one actuator of the heater for a second determined set time; de-energizing another actuator of the heater for a third determined period of time; compare, during the previous steps, the temperature detected by a temperature detector versus a target value; in case the temperature detected is higher than the target value, interrupting a drive signal to drivers for the heater; in case the temperature detected is lower than the target value, uninterrupting the signal to the drivers; and repeat the previous steps at least one time.

Abstract: The present subject matter provides a dryer appliance and a method for operating a dryer appliance. The method includes monitoring a first temperature sensor of the dryer appliance in order to determine a number of cycles of the first temperature sensor. If the number of cycles of the heating element exceeds a threshold number, a temperature set point of a second temperature sensor of the dryer appliance is reduced. The method can assist with reducing or avoiding excessive cycling of the first temperature sensor.

Abstract: A dryer appliance and a method for operating the same are provided. The method includes establishing a first temperature set point and a second temperature set point for the dryer appliance. The method also includes determining an operating condition of the dryer appliance and selecting an operating temperature of the dryer appliance from the first and second temperature set points.

Abstract: A dryer appliance is provided. The dryer appliance includes a drum that defines a chamber for receipt of articles for drying and a heating assembly for generating heated air for the chamber of the drum. A duct extends between and fluidly connects the chamber of the drum and the heating assembly. The duct includes outlets for directing heated air from the heating assembly into the chamber of the drum and also includes features for reducing temperature gradients at outlets of the duct.

Abstract: A method to compensate drying time in an electric or gas dryer machine, which comprises the steps of: read the operator parameters (dryness level, cycle type, heat level); begin a timer to measure time between beginning and Trtv; determine the load weight and the type of restrictions of the dryer; determine the dryness target voltage and the minimum drying time by means of a table of predetermined values based on the previous data; store the values in a memory; determine that the detected voltage be equal to the target voltage; calculate the additional time as a function of the heat factor and of the data previously determined; compare (Tminimum-Trtv) versus additional time and use the greater; and, add the additional time to the Trtv as compensation time.

Abstract: A clothes dryer has a first four pole motor that rotates a rotatable drum in the dryer through a transmission system. The clothes dryer has a second two pole self speed regulated induction motor connected to a blower fan in the air passageway of the dryer. The second motor rotates the fan to draw air out of the dryer and exhaust the air to an external vent. The second motor provides a long venting application and has a slip characteristic whereby the speed of the second motor automatically varies directly proportional to air flow restrictions associated with the external vent.
