Patent number: 8752404Abstract: A drum for a laundry treatment machine that is rotatably mounted within the housing of the laundry treatment machine, and wherein the drum includes a bottom disk and a jacket which are individually or jointly provided with a curved structure. The curved structure includes at least two rows of prism-type embossings that have substantially rectangular base, and the at least two rows encompass at least partially the drum. A surface of embossings that is directed in a circumferential direction of the drum is arranged at a steep angle to the jacket; an opposing surface of the embossings is arranged at a flat angle to the jacket; and lateral surfaces of the embossings are arranged at least nearly at a right angle to the jacket.Type: GrantFiled: January 2, 2009Date of Patent: June 17, 2014Assignee: BSH Bosch und Siemens Hausgerate GmbHInventors: Christoph Oertel, Uwe Ratfisch, Stephan Sommer, Wilfried Wildung

Patent number: 8393185Abstract: Fastening plastic drivers in a washing machine drum having at least two domes on the inside, which comprise a cavity extending along its center line, and are oriented perpendicular to the sheet casing of the drum and which serve to fasten the driver. A hole pattern corresponding to the arrangement of the domes of a driver is punched into the sheet casing of the drum. The driver is placed with its dome ends, which project beyond the contact surface of the driver with the sheet casing, onto the sheet casing so that the dome ends pass through the holes of the hole pattern. Counter holders are inserted from the opposite side into the cavities of the domes. From the fastening side, hold-down elements are driven against the sheet casing. Heated form punches are driven against the dome ends until the dome ends have mushroom-shape ends.Type: GrantFiled: January 27, 2012Date of Patent: March 12, 2013Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventor: Uwe Ratfisch

Publication number: 20090276966Abstract: A washing machine includes a horizontally rotatable drum having a drum shell. Hollow agitators are disposed on the inside of the drum and have a base as part of the drum shell and at least one inlet opening to allow lye into the hollow space. Outlet openings are located on a top region of each agitator for allowing lye to pour out upon rotation to an elevated position. A fixed barrier located in the hollow space of each agitator serves to divide the space to define a chamber such that upon rotation from a lowest position, the chamber fills with lye, and upon further rotation the lye flows out of the outlet openings.Type: ApplicationFiled: June 21, 2006Publication date: November 12, 2009Applicant: BSH Bosch und Siemens Hausgerate GmbHInventors: Uwe Mette, Uwe Ratfisch, Wilfried Wildung

Publication number: 20080178635Abstract: A mounting star stabilizing and rotationally mounting a washing drum of a washing machine. The mounting star comprises at least three arms near the center of the mounting star and a hollow molded body with a box-like open profile. Support points support the mounting star against the rear wall of the washing drum and are arranged at a distance from approximately the mid-length of each arm. The open profile of the arm is made of a pair of surfaces which are non-connected between themselves and are at least similar to a flat rectangle which forms the transversal section of the supports and the short sides thereof are oriented towards the rear wall of the washing drum. Both of the supports are connected by means of a third support of the identical transversal surface from arm to arm, with a support of the other arm.Type: ApplicationFiled: September 30, 2005Publication date: July 31, 2008Applicant: BSH BOSCH UND SIEMENS HAUSGERÄTE GMBHInventor: Uwe Ratfisch

Patent number: 7287402Abstract: Paddles are fastened on an inside of a drum casing by fastening elements. The paddles contain a hollow body, which is open in the direction of the drum casing and has a cross-sectional surface area similar to a triangle, and stiffening structures on the insides of its flanks. For secure and permanently stable fastening, in the region of at least some of the structures, strip-shaped installation parts are connected in a form-fitting manner, by way of a section located essentially parallel to the surface of the drum casing, to the inside of the flanks. Moreover, the sections have at least two fastening elements by which the paddle is fastened on the drum casing.Type: GrantFiled: December 17, 2003Date of Patent: October 30, 2007Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventor: Uwe Ratfisch
