Patent number: 6941680Abstract: A clothes dryer that is operatively attached to a heating system is illustrated. The clothes dryer receives heated fluid when the dryer is turned on. The dryer has a radiator that receives the heated fluid from the circulating fluid flow system. The fluid-filled radiator radiates heat into a clothes-drying chamber, which forms part of a motor-driven, rotating drum. The rotating drum tumbles the clothes as heat is projected into the drying chamber, thus driving the moisture from the clothes.Type: GrantFiled: July 3, 2003Date of Patent: September 13, 2005Inventors: Robert Zielewicz, Karen Zielewicz, Sarah Zielewicz, Matthew Zielewicz, Emily Zielewicz

Publication number: 20040237338Abstract: The invention relates to a tumble-drier and to a process that allows complete or partial sterilization or passivation of microorganisms and germs in laundry. To this end, the laundry is treated in a container (5), especially the drum of a tumble-drier, to which a stream of air is supplied for the purpose of drying the laundry. Ozone is added to said supply air stream. This ozone is preferably generated by an ozone generator (6) directly before being added to the supply air stream. The tumble-drier according to the invention comprises a container (5) for laundry, especially a drum, to which an air stream is supplied for the purpose of drying the laundry, and an ozone generator that is capable of adding ozone to the supply air stream. Said ozone generator is preferably an ozone generator working according to the principle of dielectric impeded discharge.Type: ApplicationFiled: July 21, 2004Publication date: December 2, 2004Inventors: Hanns Rump, Olaf Kiesewetter, Rainer Klein, Uwe Koziol, Jessica Gerhart

Publication number: 20040216327Abstract: A washing machine and method of controlling a drying process thereof is provided. The washing machine includes a water temperature detecting unit and a controller. The water temperature detecting unit is disposed in a condensing duct to detect temperatures of condensed water. The controller determines whether an end of a drying process is reached based upon the water temperatures detected by the water temperature detecting unit, and terminates the drying process depending on a result of the determination. Accordingly, the drying process may be terminated without delay, irrespective of various factors, such as a weight of the laundry, moisture contained in the laundry, and the temperature of cold water supplied to an inside of the condensing duct, so that a drying performance is improved, excessive drying and damage to the laundry are prevented and energy is saved.Type: ApplicationFiled: February 3, 2004Publication date: November 4, 2004Applicant: Samsung Electronics Co., LtdInventor: Young-Suk Chung

Patent number: 6779279Abstract: A dryer having a filter sensing system that warns a user that a filter requires servicing is provided. The dryer includes a drum that retains laundry. Hot air is drawn through the drum (for drying) and out an exhaust casing having a filter for removing lint and other particles. The temperature difference of the air in front of the filter (on the drum side) and behind the filter is determined using temperature sensors. When that temperature difference exceeds a predetermined threshold, a control unit causes a notice unit to produce a warning signal that informs a user that filter service is required.Type: GrantFiled: July 9, 2002Date of Patent: August 24, 2004Assignee: LG Electronics Inc.Inventors: Soon-Jo Lee, Hae Deog Jeong

Patent number: 6655047Abstract: A fire arrester for use with a clothes dryer includes a fire detector at the dryer vent to detect fires starting in the dryer and provides an electrical power disconnect means to break the flow of electrical power being supplied to operate the dryer. Optionally, the signal is applied to release an extinguishing agent or fire suppressant into the interior of the dryer just prior to shutting off the dryer blower. The output signal from the fire detector can also be used to provide various alarms, including local visual and/or alarms, as well as a remote alarm, which can be accomplished by sending a signal to a remote monitoring facility such as a home intrusion service or to a local fire department. Optionally, the activation of any of the alarm signals, and/or the activation of any of the features or functions of the fire arrester can be accomplished by using wireless communications.Type: GrantFiled: April 23, 2002Date of Patent: December 2, 2003Inventor: Andrew C Miller, II

Patent number: 6643953Abstract: A clothes dryer in accordance with the present invention includes a drum rotatably supported in a case having an interior space for drying clothes. Air for drying clothes is supplied to the suction duct that is connected to one side of the drum. An extension duct extending from the suction duct into the drum supplies the air from the suction duct into the drum. An exhaust duct is connected to the other side of the drum for exhausting the air that is used to dry clothes to the outside of the case. The clothes dryer uniformly dries clothes inputted into the drum as the dryer directly transmits heated air to the center portion of the drum, thereby improving clothes drying efficiency.Type: GrantFiled: January 9, 2002Date of Patent: November 11, 2003Assignee: LG Electronics Inc.Inventors: Sung Bae Song, Sang Wook Hong, Sang Heon Yoon, Hwan Joo Myung
