Patent number: 10640911Abstract: A method of controlling a drying cycle for drying delicate laundry in a laundry drying apparatus, in particular in a dryer or in a washer-dryer, wherein the laundry drying apparatus has a cabinet, a rotatable drum adapted to receive laundry to be dried, and a drying air channel arrangement designed to guide drying air through the drum for drying the laundry in the drum. The drying air is heated by a heating element and a blower is arranged in the channel arrangement adapted to convey the drying air. A drum motor is adapted to rotate the drum selectively in a main rotation direction (58) and in a counter rotation direction (66). The method includes a drying phase sequence (60) having a first drying phase (62) and subsequently a second drying phase (64). In the first drying phase (62) the drum is rotated alternately in the main and the counter rotation direction (58, 66) while the drying air is conveyed at a first average flow rate through the drum.Type: GrantFiled: June 26, 2015Date of Patent: May 5, 2020Assignee: Electrolux Appliances AktiebolagInventor: Michele Bisaro

Patent number: 9624619Abstract: A method of controlling a rotatable-drum laundry drier to dry delicate laundry in a drum of the rotatable-drum laundry drier. The method includes the steps of feeding drying air into the drum; rotating the drum at a variable rotation speed about an axis of rotation; rotating the drum at a first rotation speed higher than, or equal to a rotation speed, at which centrifugal acceleration of the inner surface of the drum equals gravitational acceleration; making interruptions in rotation of the drum at the first rotation speed; and performing, at each interruption, one or more rotation cycles at a second rotation speed, so that, at each cycle, at least part of the laundry slides/tumbles slowly inside the drum while remaining in contact with the inner surface of the drum and/or another part of the laundry contacting the drum.Type: GrantFiled: November 25, 2011Date of Patent: April 18, 2017Assignee: ELECTROLUX HOME PRODUCTS CORPORATION N.V.Inventors: Fabio Altinier, Michele Bisaro, Roberto Ragogna

Patent number: 9271549Abstract: A bracelet includes a plurality of links assembled in an articulated manner using pins. Each pin passes through interlocking parts of links in which a cylindrical passage is arranged where a pin can slide relatively freely. In order to ensure the position of the pin once the links have been assembled, a locking element is arranged in a cavity made in one of the links so as to partially intersect the passage in which the pin is arranged. This pin includes a groove, which is penetrated by an external part of the locking element when the element is in the closed position. Pressing on the locking element, then rotating it by an angle of 90°, releases the external part of the pin groove so that the pin is then released.Type: GrantFiled: April 4, 2008Date of Patent: March 1, 2016Assignee: Glashütter Uhrenbetrieb GmbHInventors: Mathias Elbe, Giuseppe Anelli, Michele Bisaro

Publication number: 20140115916Abstract: A method is provided for controlling a drying operation of a rotatable-drum laundry dryer (1) having a rotatable drum (3) for loading laundry (5) and at least an electrode sensor (22) for sensing dryness of the laundry (5). The method includes the step of detecting the presence/absence of moist laundry (5) inside the rotatable drum (3) by the electrode sensor (22). If a presence of moist laundry inside the rotatable drum (3) is detected, a drying cycle is started. The dryness of the laundry (5) is sensed during the drying cycle and a cycle time (TD) at which the sensed dryness reaches a preset dryness threshold is measured. If the cycle time (TD) is lower than a preset dryness threshold time (Sm), the drying cycle is continued for a first additional time (D1), and the drying cycle is stopped at the end of the first additional time (D1).Type: ApplicationFiled: June 21, 2012Publication date: May 1, 2014Inventors: Fabio Altinier, Fabio Pasut, Michele Bisaro, Roberto Ragogna

Each pins passes through the interlocking parts of links in which a cylindrical passage is arranged where a pin can slide relatively freely. In order to ensure the position of the pin once the links have been assembled, a locking element (12) is arranged in a cavity (18) made in one of the links so as to partially intersect the passage in which the pin is arranged. This pin includes a groove (22) which an external part (35) of the locking element penetrates when the element is in the closed position. Pressing on the locking element then rotating it through an angle of 90° releases the external part of the pin groove such that the pin is then released. The pin locking device thus allows the links to be assembled in a reversible manner and the length of the bracelet to be varied by adding or removing at least one link.Type: ApplicationFiled: April 4, 2008Publication date: October 9, 2008Applicant: Glashutter Uhrenbetrieb GmbHInventors: Mathias Elbe, Giuseppe Anelli, Michele Bisaro
