A dryer includes a main body, a drying chamber provided inside the main body and configured to accommodate objects to be dried, a conveying unit configured to convey the objects to be dried, a sensor unit configured to sense information on states of the objects to be dried, and a control unit configured to control the conveying unit to move the objects to be dried based on the information sensed by the sensor unit.

A method for controlling a laundry drying machine having a laundry treating chamber and a control unit which receives a signal indicative of laundry moisture from a moisture sensor. The method includes receiving a user input of a laundry treating program, and, in the machine initialization phase, comparing the laundry moisture indicated by the signal to a first threshold, which is stored in the control unit and is indicative of dried laundry or empty threating chamber. If the signal is determined to be equal or less than the first threshold, one or more of the following actions is performed: carrying out only a portion of the selected laundry treating program; skipping the program main phase; starting the program final phase; stopping the laundry treating program; providing a notification of dried laundry and/or empty treating chamber.

A dryer includes a plurality of piezoelectric transducers in electrical communication with a high frequency piezoelectric oscillation generator. The piezoelectric oscillation generator controls the duty cycle and resonant frequency source signal that drive the plurality of piezoelectric transducers non-continuously. The piezoelectric transducers dry the wet articles without heating air passing through the articles.

The present invention provides a retrofit device to automatically shut off a clothes dryer to prevent over drying. The device includes a humidity sensor apparatus for placement inside a clothes dryer. The Sensor communicates with a Receiver device connected to an electrical wall outlet and to the electrical plug of the clothes dryer. The Receiver turns off the power to the clothes dryer when the humidity level in the clothes dryer drops to a predetermined level, as detected by the Sensor.

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.
