Patent number: 8555523Abstract: A method carried out without sealing elements inside fixed parts in the front area of a condensation dryer. A process air channel arranged in a shield is made of a plastic material and is provided with a vertical dividing surface which is placed at the level of a heat exchanger reception area in front of a base module. Said base module and the shield are assembled without additional sealing means. The tightness of the process air guide along the passage from the shield to a condenser is obtainable by supporting surfaces devoid of welds and hitches on the edges of the heat exchanger insertion opening, sealing elements placed on the circumference of a heat exchanger are pressed to each other when the dryer is prepared to operate.Type: GrantFiled: January 12, 2006Date of Patent: October 15, 2013Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Lothar Dittmer, Holger Löffler

Patent number: 7946054Abstract: An assembly which is a composite including an end shield and a front wall. The size and shape of the end shield are adapted to the inner face of the front wall. Both parts are dimensioned and formed in such a way that they can be interconnected in a fixed manner to form a stable composite resembling a sandwich assembly. The joint surfaces between the front wall and the end shield lie on perpendicular planes and extend for some distance. The construction and connection of the individual parts and of the composite give the front region of the tumble dryer a high degree of rigidity, which obviates the need for additional reinforcement measures. The assembly thus saves material and mounting costs and resources.Type: GrantFiled: January 26, 2006Date of Patent: May 24, 2011Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Lothar Dittmer, Holger Löffler

Patent number: 7946057Abstract: A support structure for a clothes dryer comprising modular units for receiving functional parts and an air duct components. The modular units are incorporated into the support structure. The inventive support structure for stabilizing the clothes dryer comprises a front part in the form of a combined body provided with an end shield, a front wall, a base module on the bottom side comprising a base body and a process air lid, a rear module comprising the rear wall, a heating device and a cover. The joining surfaces between the modular units are located on a vertical plane. Connections are constructed in such a way that they are devoid of sealing elements which are currently used for joining surfaces. With respect to known embodiments, the inventive clothes dryer structural design is producible with a low material consumption and, in general, can be produced in a more rational manner.Type: GrantFiled: January 9, 2006Date of Patent: May 24, 2011Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Lothar Dittmer, Holger Löffler

Publication number: 20100236091Abstract: In a sensor system for a domestic laundry dryer in which a canister-shaped condensate container 5 is mounted in a receiving chamber 15, at least one sensor S2 is used to monitor the insertion of the condensate container 5. Another sensor S1 takes over the detection of a limiting filling level 12 of the condensate in the condensate container 5. When this level is reached, emptying of the condensate container 5 is requested by switching an audible and/or visual attention signal. This container can be removed from the inside of the loading door 6. At least one sensor S2 is a non-contact switch. The sensor system contains a circuit arrangement which can be influenced by the sensor or sensors S for controlling the drying program of the laundry dryer. The sensor or sensors preferably S contain magnetically influencable switches. They form a switching system comprising a magnetically influencable switching contact 1 and a magnet 2.Type: ApplicationFiled: January 30, 2007Publication date: September 23, 2010Applicant: BSH Bosch und Siemens Hausgerate GmbHInventors: Lothar Dittmer, Bodo Urich

Publication number: 20080110042Abstract: A method and a device for drying wet washing that has been placed in a drier device equipped with a rotatable drum. The stream of drying air is guided in such a way that the surface of the washing to be dried that is exposed to said stream is maximised. To achieve this, the invention provides a washing spacer, at least some sections of which are flexible and on which the washing to be dried can be placed. The spacer can then be rolled up together with the washing to be dried into a preferably cylindrical form. The washing spacer and the wet washing, which is rolled with a radial distance between its layers, is connected in an air-conductive, sealed manner to the extraction opening, allowing the stream of drying air to be guided through the washing spacer and the washing to be dried. Said method is extremely effective and reduces the drying times.Type: ApplicationFiled: October 18, 2005Publication date: May 15, 2008Applicant: BSH Bosch und Siemens Hausgeräte GmbH üInventors: Uwe Ackermann, Lothar Dittmer, Uwe-Jens Krausch, Harald Moschutz, Kai Nitschmann, Ingo Schulze, Andreas Stolze
