With respect to an especially efficient use of energy required for drying, a drier for drying items to be dried, comprising a receptacle for the items to be dried, an air guide for guiding air to the receptacle and a heating device for heating the air is designed and further developed in such a way that the receptacle comprises a plurality of modules (1, 2, 3, 4), arranged one behind the other, for heating, drying or cooling the items to be dried, and that at least one module (1, 2, 3, 4) is associated with a conveying device (5) for conveying the items to be dried from this module (1, 2, 3) or any module (1, 2, 3) to the next module (2, 3, 4).

A dual type drying machine includes a main drying unit, a main unit door configured to open and close a front side of the main drying unit, an auxiliary drying unit positioned vertically above the main drying unit and defining a laundry accommodation space, an auxiliary unit door configured to open and close a top surface of the laundry accommodation space, a cabinet that accommodates the main drying unit and the auxiliary drying unit, the cabinet defining an exterior of the drying machine, and an operation panel disposed at a front side of the auxiliary drying unit. When the auxiliary unit door is closed, top surfaces of the cabinet and the auxiliary unit door define a top exterior surface of the drying machine.

A dryer includes a cylinder, a heater, a motor, a temperature sensor and a controller. The heater heats air and delivers the heated air into the cylinder. The motor is used to drive the cylinder to rotate. The temperature sensor includes a thermopile array sensor and a signal processor. The thermopile array sensor is used to sense an infrared light radiated from clothing and output a sensing signal. The signal processor is used to process the sensing signal to obtain at least one of a temperature distribution uniformity and an average temperature of the clothing, and output a control signal according to the at least one of the temperature distribution uniformity and the average temperature of the clothing. The controller determines to stop the drying schedule according to the control signal. The above-mentioned dryer can stop the drying schedule automatically, so as to save energy.

A laundry treating apparatus comprises a drum receiving clothes; a fan supplying air to the drum; a heater heating the air supplied to the drum; and a dry level sensing unit determining a dry level of the clothes. A control method comprises setting a dry time; supplying air to the clothes by operating the fan or operating the fan and the heater, and controlled to be performed for the dry time; and resetting the dry time, when the dry level measured by the dry level sensing unit at a time past a preset reference time period from the start of the air supply step is less than a preset reference dry level, wherein resetting the dry time step adds more time to the reference time period.

An embedded temperature sensor may be attached to or otherwise associated with a textile in order to measure one or more temperatures of the textile. Temperature information received from one or more embedded temperature sensor(s) throughout the course of a dryer cycle may be analyzed to determine dryness of one or more textiles in a dryer, determine whether one or more textiles in the dryer are overdry, generate an indication of the dryness of the one or more textiles in the dryer, and/or to control one or more dryer cycles of the dryer, such as by automatically turning-off the dryer when one or more of the textiles in the dryer are determined to be dry. The embedded temperature sensor may further be used to validate a cleaning process in a cleaning machine.

A dryer monitoring system receives dryer information from one or more sensors concerning operation of one or more dryers, such as clothes dryers. For example, the dryer monitoring system may receive temperature and/or humidity information from one or more dryers. The dryer monitor analyzes the dryer data to determine whether textiles in the dryer are dry. The dryer monitor may analyze one or more states and/or one or more indicators (patterns in the dryer data) during the dryness determination.

A method is provided for operating a laundry dryer having a rotatable drum for accommodating clothes to be dried and an apparatus for circulating drying air through the drum. The method comprises the steps of performing a drying cycle selected by a user, wherein the drying cycle comprises predetermined drum movements over time depending on the cycle selected, detecting values indicative of the temperature of the drying air exiting the drum, based on said detected values, determining that the clothes inside the drum are in tangling conditions and starting an untangling operation for untying the clothes inside the drum. The untangling operation comprises modification of the predetermined drum movements. The modification comprises at least one of the following: stopping the rotation of the drum, reversing the rotation of the drum, modifying the speed of rotation of the drum, at the end of the untangling operation, either resuming the predetermined drum movements associated to the drying cycle that was running before starting the untangling operation, or performing drum movements over time different from the predetermined drum movements associated to the drying cycle that was running before starting the untangling operation.

A wireless communication assembly includes a driver module connected to a first portion of a machine, such as a laundry machine, and a receiver module connected to a second portion of the machine, such as a rotatable drum. The first module includes a primary coil configured to generate an electromagnetic field and a first wireless transceiver. The second module includes a secondary coil configured to convert energy within the electromagnetic field into electric power, and a second wireless transceiver powered by the secondary coil and configured to communicate with the first wireless transceiver. One or more sensors may be positioned within the drum to measure various conditions. The receiver module may be powered by the secondary coil and when powered on, may communicate data from the one or more sensors to the first module.

A sauna cabin enclosure comprised of two half cabins, one half being smaller than the other, such that one half can fit inside the other and can slide to contract or expand partially or fully, thereby increasing or decreasing the air volume inside and the overall external size. This cabin has infrared heating, full spectrum lighting and a steam generator. When the cabin size is reduced by means of a hand crank or a motor, the air volume inside the cabin is decreased, allowing air temperature to increase proportionally. The cabin can be compressed together to minimize required floor space.
