Patent number: 9512554Abstract: A device that has a component within a process air circuit of a washer dryer or tumble dryer; a condensate water trough in which condensate water is collected that is formed in the process air circuit as a result of drying damp laundry; and a first lever arm rotatably fastened to a rinse tank above the component. The component is to be cleaned and the condensate water is conducted from the condensate water trough to the rinse tank. Further, the condensate water is dispensed from an outlet opening of the rinse tank to the component. The rinse tank has a closure to selectively open and close the outlet opening and an actuator to actuate the closure. Also, the closure has a sealing head that is connected to the first lever arm and that closes the outlet opening.Type: GrantFiled: July 9, 2009Date of Patent: December 6, 2016Assignee: BSH HAUSGERÄTE GMBHInventors: Martin Baurmann, Frank Kohlrusch, Günter Steffens, Oliver Wuttge

Patent number: 9127399Abstract: An electrical domestic appliance includes a fire-prevention medium for fighting a fire in the domestic appliance in an early stage. The fire-prevention medium includes an active substance, which releases water, carbon dioxide and/or nitrogen under the effect of heat at a temperature below 100° C. The fire-prevention medium has a core, which contains the active substance and a carrier material, and a shell, which surrounds the core.Type: GrantFiled: May 5, 2011Date of Patent: September 8, 2015Assignee: BSH Hausgeräte GmbHInventors: Brian Chatot, Frank Kohlrusch, Günter Steffens

Patent number: 8863401Abstract: A household laundry dryer has at least one filter container which includes a chamber with an inlet for condensate water to be cleaned. The chamber has a first outlet, a second outlet and a filter element which is arranged between the inlet and the first outlet and which divides the chamber into an inlet-side first chamber part and a second chamber part. The filter container can be configured in such a way that the inlet is arranged below the filter element and the filter element is arranged below the first outlet, and the second outlet opens into the first chamber part. Particles deposited on the filter element by water being pushed through the inlet into the chamber are detachable from the filter element by water flowing back into the chamber, when no water is being pushed through the inlet, and removable through the second outlet.Type: GrantFiled: April 15, 2010Date of Patent: October 21, 2014Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Klaus Grunert, Frank Kohlrusch, Andreas Ziemann

Patent number: 8707579Abstract: In a method for operating an adsorption dryer, a process air flow, generated by at least one blower, is routed at least at times through an adsorption apparatus and over a textile goods in care during a textile care process in a “dry” operating mode to thereby charge a reversibly dehydratable adsorbent of the adsorption apparatus with moisture. A charge state of the adsorbent with water is detected and is displayed at least after the end of the “drying” textile care process. The absorbent is desorbed at least in part during a subsequent, selected and started textile care process in a “refresh” operating mode, and the desorbed moisture is routed as a moist process air flow into a receptacle for refreshing textile goods which are stored or hung in a stationary manner.Type: GrantFiled: August 16, 2010Date of Patent: April 29, 2014Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Frank Kohlrusch, Ulf Müller, Andreas Stolze

Publication number: 20120005914Abstract: A rinsing device for rinsing at least one component to be cleaned of a laundry drying machine by means of a rinsing fluid includes a rinse container having an outlet opening for draining the rinsing fluid to the component. A sealing part selectively opens and closes the outlet opening, with the sealing part having a sealing head for sealing the outlet opening. A spring element connects the sealing head to the rinse container and urges the sealing head against the outlet opening. The sealing part of the rinse container is activated by an activation unit.Type: ApplicationFiled: March 15, 2010Publication date: January 12, 2012Applicant: BSH BOSCH UND SIEMENS HAUSGERÄTE GmbHInventors: Frank Kohlrusch, Günter Steffens
