  • Publication number: 20090283111
    Abstract: 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.

  • Publication number: 20070074746
    Abstract: 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.

  • Patent number: 6536451
    Abstract: 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.

  • Patent number: 5904166
    Abstract: 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.
