A method of controlling a dryer includes rotating a drum within the dryer in a first direction, detecting at least one of temperature or relative humidity of air discharged from the drum while the drum is rotating in the first direction, and sensing occurrence of entanglement inside the drum by comparing a variation rate of at least one of the detected temperature or the detected relative humidity with a corresponding reference value. The method also includes, based on sensing that the entanglement has occurred, reversing a rotation direction of the drum by rotating the drum in a second direction that is opposite the first direction, and further, based on reversing the rotation direction of the drum upon sensing that the entanglement has occurred, maintaining the second direction of rotation of the drum for a preset time.

An apparatus and method towards a laundry treating appliance for drying laundry comprising a rotatable drum at least partially defining a treating chamber and having a front and a rear where at least one conductivity sensor is located within the treating chamber, and a motor rotating the drum tumbles laundry within the treating chamber to enable contact of the laundry with the conductivity sensor.

A dryer apparatus is disclosed comprising a container having a container inlet and outlet, a pump that is configured to motivate a first air-vapor mixture flow via the container inlet and via the container outlet, a heating device configured to heat the first air-vapor mixture, a selector with at least two states, a compressor that is configured to compress and motivate a part of the first air-vapor mixture flow as a second air-vapor mixture flow, to flow through a first heat exchanger and to flow through a second heat exchanger and a pressure reducing device that is configured to reduce the pressure of said second air-vapor mixture downstream said first heat exchanger. The selector is configured to direct most of the first air-vapor mixture to flow in a closed cycle through the container, or configured to exchange most of the first air-vapor mixture with air located outside the apparatus.

A method for controlling a laundry processing apparatus, according to an embodiment of the present invention, is a method for controlling a clothes processing apparatus, comprising the steps of: inputting a drying start command; forwardly rotating a drying drum and a drying fan; supplying hot air into the drying drum; operating a timer so as to calculate drying time; and operating a dryness sensor so as to detect the dryness of laundry, wherein a controller determines that the laundry is tangled, if a dryness sensing value (K) detected by the dryness sensor is greater than or equal to a first set value (k1) before a first set time (T1) elapses after drying starts, and the controller performs a primary laundry untangling process for reversely rotating the drying drum for a second set time (T2).
