A laundry appliance includes a drum that is rotatably mounted within a cabinet and defines a chamber for receiving articles of clothing. Primary and ambient air duct systems provide fluid communication between a conditioning system and at least one of the chamber of the drum and an ambient environment, respectively. A blower fan urges air through the conditioning system and a damper system is operably coupled to the ambient air duct system for selectively regulating a flow of ambient air. A controller is configured to receive a command to initiate a dehumidification cycle, operate the conditioning system and the blower, and regulate the damper system to permit the flow of ambient air to pass through conditioning system and through the ambient air duct system, thereby dehumidifying the ambient environment.

A clothes dryer comprising: a cabinet including a front panel on which an inlet is formed, a drum rotatably arranged in the cabinet and having a front opening and a rear opening, a front cover linking the inlet of the cabinet and the front opening of the drum, and including a slope portion having a diameter decreasing as being directed toward the inlet of the cabinet from the front opening of the drum, a rear cover connected to the rear opening of the drum and having an air inlet formed at the rear cover to allow air to be supplied toward the rear opening of the drum, and a sensing device arranged on the slope portion for sensing humidity in air discharged from the front opening of the drum.

A tub for use in a washer or dryer that is dividable into compartments by use of a removable dividing wall. The removable dividing wall can be inserted manually or mechanically into position and held in place with a removable wall securing device. The tub has expanding and contracting capabilities that allows the diameter of the tub to be altered.

A method to control a laundry drying machine having a rotatable drum, a motor for rotating the drum, and a hot air generator for supplying a drying airflow to the drum. The method includes: collecting physicals quantities during an initial phase of said drying cycle, performing an estimation of polynomial coefficients of a cubic polynomial model indicative of an estimated change of a laundry moisture value over the time based on respective linear polynomial models comprising the collected physicals quantities, performing an estimation of the laundry moisture value by the cubic polynomial model based on the estimated polynomial coefficients, and controlling the motor and hot air generator during a drying cycle, based on one or more physicals quantities associated with the drum loaded with laundry, the electric motor and the hot air generator.

A dryer is disclosed. The dryer includes a heat exchanger configured to remove moisture from air flowing and heat and discharge the moisture-removed air, a drum containing a material to be dried, a humidity sensor configured to detect a humidity of the air flowing from the drum, a fan configured to generate a flow of the air flowing along a flow path formed so that the air discharged from the heat exchanger flows to the heat exchanger via the drum and the humidity sensor, and a processor configured to determine a dried state of the material to be dried based on the humidity detected through the humidity sensor, and the humidity sensor is disposed at a position where a flow velocity of the air is equal to or higher than a predetermined velocity in the flow path formed between the drum and the heat exchanger.
