  • Patent number: 10722100
    Abstract: A household dishwasher includes a wash container for holding dishes to be washed and a fill reservoir attached to the wash container. The fill reservoir is filled with fresh water from a fresh water network, and a quantity of fresh water required for the wash sub-cycle is removed from the fill reservoir and feed into the wash container. A heat pump includes an evaporator which is thermally coupled to the fill reservoir to extract heat energy from stored fresh water, and a condenser via which heat energy is fed into an interior space of the wash container. Disposed between the interior space of the wash container and an interior space of the fill reservoir is a single-layer or multilayer insulation material system to reduce a heat flow from the wash container.

  • Patent number: 9078557
    Abstract: A dishwasher is provided that includes a washing compartment and a sorption drying system to dry items to be washed, wherein the sorption drying system has a sorption container that contains reversibly dehydratable sorption material. The dishwasher further includes an air ducting channel to connect the sorption container with the washing compartment in order to generate an air flow. The air ducting channel has an inlet-side tube section and the sorption container and/or the inlet-side tube section has flow conditioning elements. Each flow conditioning elements has an air passage such that, to a large extent, an equalization of a local cross-sectional profile of an air flow is effected when air flows through the sorption container in a throughflow direction of the sorption container.

  • Patent number: 8603255
    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.

  • Patent number: 7887642
    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.
