Publication number: 20100037917Abstract: A device and method for handling waste water to-be-discharged out of a dishwashing machine that includes a pump well and a sump section, with the sump section communicating with the pump well in the lower regions of the dishwashing machine through an inflow section. The device also contains a valve located in or operating with the inflow section that blocks the influx of waste water from the pump well into the sump section when the valve is closed. The valve allows the influx of waste water from the pump well into the sump section when the valve is opened.Type: ApplicationFiled: August 18, 2009Publication date: February 18, 2010Applicant: BSH BOSCH UND SIEMENS HAUSGERATE GMBHInventors: Heinz-Werner Giefer, Georg Hechtl, Hans-Peter Nannt, Horst Sipple

Publication number: 20090283111Abstract: A dishwasher, in particular a domestic dishwasher, having at least one substantially closed water circuit in which washing liquor is recirculated in a first direction in accordance with a program control unit, with the washing liquor being conveyed through a filter element during recirculation in order to filter impurities. Provision is made of a device for reversing the direction of flow, and this allows recirculation of the washing liquor in a second direction, which runs counter to the first direction, in order to flow through and eliminate impurities from a first screen, with the first screen being arranged in the water circuit in such a way that liquid forcibly flows through the first screen during recirculation of the washing liquor both in the first and in the second direction.Type: ApplicationFiled: July 11, 2006Publication date: November 19, 2009Applicant: BSH Bosch und Siemens Hausgerate GmbHInventors: Egbert Classen, Helmut Jerg, Hans-Peter Nannt, Roland Rieger

Publication number: 20070079850Abstract: A dishwasher machine with a compact device for spraying items to be rinsed is provided whereby the rinsing liquid is regularly sprayed in the rinsing container and the spray jets created by the spray device can be varied. To this end, the rinsing device comprises at least one spray channel which guides a rinsing liquid and comprises, on a side thereof facing the inside of the rinsing container, openings for the rinsing liquid and two open ends via which rinsing liquid can be supplied in a pressurized manner. At least one distributor is provided for regulating the supply of rinsing liquid to the spray channel in lieu of conventional mobile components such as spray arms, and various spray patterns can be produced by means of the distributor, improving the cleaning action of the dishwasher machine.Type: ApplicationFiled: November 4, 2004Publication date: April 12, 2007Applicant: BSH Bosch und Siemens Hausgerate, GmbhInventors: Helmut Jerg, Hans-Peter Nannt

Publication number: 20070074746Abstract: A device for spraying spray products in a dishwasher enables the dishes to be impinged upon with dishwashing fluid in an efficient manner and to avoid wear and tear caused by moving parts and to provide trouble-free operation. The spraying device sprays dishwashing fluid into the inside of the washing container and includes at least one spray channel that guides at least one dishwashing liquid and is integrated into the bottom, top and/or wall area of the washing container, whereby openings which are oriented toward the interior of the washing container are provided on one side and enable the dishwashing fluid to pass therethrough. An improved more homogeneous distribution of dishwashing fluid is provided and it is possible to dispense with moving parts, such as spray arms for the distribution of dishwashing fluid, leading to greater freedom in terms of washing container and wash basket design.Type: ApplicationFiled: October 8, 2004Publication date: April 5, 2007Applicant: BSH Bosch und Siemens Hausgeräte, GmbHInventors: Helmut Jerg, Hans-Peter Nannt

Patent number: 6536451Abstract: The frontloading dishwasher has a dishwashing compartment and a door mounted on the machine body such that it can be pivoted about a horizontal axis for closing a loading opening of the dishwashing compartment. The bottom border of an inner wall of the door, forming a door lip, engages behind a compartment skirt that rises from the dishwashing-compartment base. A seal is arranged between the door and the dishwashing compartment. The seal includes a sealing strip that extends across the entire door width. Satisfactory sealing of the dishwasher is ensured over a long period of use, dirt deposits in the sealing region are avoided, and only a low level of force for moving the door is required in that a guide and securing device for the seal is provided, for securing the seal in the rest position and for guiding the seal during movement of the door.Type: GrantFiled: January 22, 2002Date of Patent: March 25, 2003Assignee: BSH Bosch und Siemens Hausgerate GmbHInventors: Georg Hechtl, Hans-Peter Nannt, Peter Huber

Patent number: 5904166Abstract: A front-loading dishwasher includes at least one basket movable out of the machine toward the front. At least one spray arm is rotatably disposed below the basket, has spray nozzles aimed at the basket and is supported on a fluid supply line that extends from one wall of the machine and is connected to a recirculating pump. A portion of the fluid supply line protruding approximately horizontally into a tub in the region of the bottom of the basket ends in a 90.degree. elbow with an outlet stub pointing downward. The spray arm rests with two wall portions located at different horizontal levels on bearing points of the elbow, which creates a simple spray arm support, in which bearing friction is substantially avoided.Type: GrantFiled: April 3, 1997Date of Patent: May 18, 1999Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Hans-Peter Nannt, Claus Kother
