Additionally, the present invention relates to a method of storing and drying articles comprising suspending the articles in a wardrobe, the interior of said wardrobe comprising an air circulation fan and an exhaust vent at the bottom; an intake vent at the top; and suspending means for suspending the articles. The articles that are difficult or take more time to dry can be placed closest to the fan. The wardrobe can have a rigid or flexible interior cavity and the flexible wardrobe can be capable of hanging on a rod and additionally can be packed in a bag with or without a kit with support poles and feet.Type: ApplicationFiled: October 27, 2014Publication date: April 30, 2015Inventor: Richard Goulet

Patent number: 8991066Abstract: An adaptor can convert a conventional hot air clothes dryer to draw air from outside instead of inside a building, and comprises an adaptor housing securable over the air intake region of the dryer in fluid communication with the air inlet of the dryer, with an adaptor housing inlet connectable to an air intake linkage. A filter and filter bypass assembly can be used in combination with the adaptor. The assembly comprises an outer enclosure and an inner enclosure inside the outer enclosure. An inner enclosure inlet and inner enclosure outlet define a first airflow path through the inner enclosure and an outer enclosure inlet and outer enclosure outlet define a second airflow path through the outer enclosure and bypassing the inner enclosure. The inner enclosure and the outer enclosure have a common aperture for insertion of a filter into the inner enclosure across the first airflow path.Type: GrantFiled: February 24, 2011Date of Patent: March 31, 2015Inventor: Bradley J.

Patent number: 8973282Abstract: A secondary lint trap couplable between a laundry dryer and a building-embedded vent duct. The trap has an elongate housing. Aligned inlet and outlet apertures are formed in bottom and top sides of the housing's rearward ends. A tray is removably insertable within the housing. A screened aperture in the tray is aligned between the inlet and outlet apertures when the tray is inserted within the housing. The housing is mountable above the dryer such that the inlet and outlet apertures extend rearwardly of the dryer. This facilitates coupling of the dryer's exhaust outlet to the inlet aperture through one 90° elbow via a first short, substantially straight, elbowless conduit; and facilitates coupling of the vent duct to the outlet aperture through one other 90° elbow collar via a second short, substantially straight, elbowless conduit.Type: GrantFiled: February 19, 2010Date of Patent: March 10, 2015Assignee: Ecco Heating Products Ltd.Inventor: David Thomas Mackay

Patent number: 8950084Abstract: A semi-drying method of a washing machine, and a ventilating structure and a control apparatus for the same. In the semi-drying method, the dehydration and disentanglement of cloth are repeated plural times, and a washing tub is rotated at a designated dehydration speed for a time longer than that of the conventional dehydrating operation so as to minimize the jamming of the cloth into water pores of the washing tub, thereby increasing the dehydration degree of the cloth compared to the conventional dehydrating operation, removing offensive odors from the cloth, preventing damage to the cloth, allowing a user to select the duration of a semi-drying operation and to see the state of the semi-drying operation, and ventilating the washing tub during the semi-drying operation to improve the dehydration degree of the cloth.Type: GrantFiled: May 7, 2010Date of Patent: February 10, 2015Assignee: LG Electronics Inc.Inventors: Seok Kyu Park, Ki Ho Kang, Yong Kyu Cho

Patent number: 8919006Abstract: A laundry drying machine (1) includes a casing (2) containing a rotatable drum (4) for holding the laundry (5) to dry, and a drying air circuit (6) for conveying a drying air flow towards the inside of the drum (6) and from it to the outside. At least one filter (12) is provided for intercepting the fluff dragged out of the laundry (5) by the drying air flow. Vibrating means (19) are adapted to cause the filter (12) to vibrate, so as to drop down the fluff from the filter (12). The filter (12) is selectively positionable between an operational position in which the filter (12) is arranged in a seat (11) intercepting the drying air circuit (6), and an extracted position in which the filter (12) is removed from the seat (11), outside the drying air circuit (6). The vibrating means includes an exciter, associated to the casing (2), and an exciter-responsive element, associated to the filter (12).Type: GrantFiled: June 30, 2009Date of Patent: December 30, 2014Assignee: Electrolux Home Products Corporation N.V.Inventors: Giancarlo Arrigoni, Carlo Urbanet, Alberto Bison, Maurizio Ugel, Giancarlo Gerolin

Publication number: 20140360040Abstract: A laundry dryer is provided with an air recirculation channel which recirculates air from an air exhaust channel to an air supply channel. The air recirculation channel comprises a recirculation air filter which removes debris from the recirculated air before it is redirected to the air supply channel. The recirculation air filter is removably accessible behind an access door at a peripheral region of an access passage to the drying chamber such that it may be easily serviced by a user of the laundry dryer. In some embodiments, the air recirculation channel may comprise a nozzle with an outlet which is concentrically arranged at an inlet of the air supply channel. In these embodiments, the nozzle may direct the recirculated air to the air supply channel such that it is enveloped by fresh air entering from within a cabinet of the laundry dryer.Type: ApplicationFiled: June 7, 2013Publication date: December 11, 2014Applicant: Electrolux Appliances AktiebolagInventors: Luciano SARTOR, Nicola BARUFFALDI, Flavio NOVIELLO
