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: A dryer appliance and a method of operating the same are provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber that is in fluid communication with a conditioning system of the dryer appliance. The conditioning system heats air circulating therethrough. A variable speed blower fan is provided to circulate air between the conditioning system and the chamber. A sensor is positioned at or proximate a drum exit of the drum. A controller of the dryer appliance receives an input indicative of the relative humidity of the air at the drum exit. Based on the received input, the controller determines a control command. The control command can be routed to a blower fan motor operable to drive the blower fan. The blower fan motor receives the control command and adjusts a flow rate of the air exiting the drum exit.

Abstract: A tumble dryer has a drum for laundry, a drive motor for the drum, an air supply to the drum and an air discharge from the drum, a fan, including a fan drive, for generating an air stream to the drum through the air supply and away from the drum through the air discharge, and also heating means for heating the air stream. The temperature of and the moisture in the air which is discharged from the drum are detected. The profile of said temperature and moisture is compared with prespecification curves, which are stored in a memory, for the profile of said temperature and moisture by means of calculation means depending on the drying phase of the laundry. The operating point of the prespecification curve at which the drying program is located is determined in this way. The control arrangement influences the further drying program, on the basis of the operating point, by way of adjusting the temperature and/or the intensity of the air stream.

Abstract: A clothes dryer apparatus and system that reduces the buildup of electric charges within a dryer drum by introducing ions. The system monitors the voltage within the drum by taking measurements on voltage sensor assembly. The sensor assembly obtains a voltage when two areas of a fabric, or two separate items of the clothing, contact the sensor. If a threshold voltage is obtained, an ion generator introduces cations and anions into the drum of the dryer to neutralize the static charge of the clothing. The reduction of static electricity increases efficiency as the clothing items do not stick together which permits better heat flow and increases safety by reducing the amount of electrical charge within the drum.

Abstract: A dryer appliance and a method of operating the same are provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber that is in fluid communication with a conditioning system of the dryer appliance. The conditioning system heats air circulating therethrough and removes water from the process air. A collection tank collects the water and a drain pump removes water from the collection tank intermittently when the water reaches a predetermined level. The frequency at which the drain pump removes water from the collection tank is utilized to determine the moisture extraction rate indicative of the rate at which moisture is removed from the clothes. The moisture extraction rate is utilized to control the mass flow rate of refrigerant in a heat pump sealed system or the process air flow rate through the closed loop air circuit.
