Abstract: A dishwasher, in particular a household dishwasher, includes: a washing container having a washing compartment and which receives washing items to be cleaned; and a heat pump device which has an evaporator which is arranged within a tank filled with water. The tank is fluidically connected to the washing container and to a fresh water inlet device. The tank is arranged below the washing container and has a top wall facing a washing container bottom.

Abstract: A cleaning device, in particular a dishwasher, includes: a cleaning container having a cleaning chamber and accommodating cleaning material to be cleaned; a heat pump device which has an evaporator arranged inside a heat storage medium tank; and an intermediate storage positioned above the heat storage medium tank, the intermediate storage receiving liquid heat storage medium displaced from the heat storage medium tank.

Abstract: A method for operating a vacuum cleaner includes providing a vacuum cleaner including a motor-driven fan, a pick-up device configured to pick up an air-dust mixture that is disposed on a suction side of the fan, a dust separator including at least one cyclone separator and a valve element disposed between the pick-up device and the fan. The dust separator is disposed between the pick-up device and the fan. The valve element is operated so as to connect a flow path leading from the pick-up device through the at least one cyclone separator to the fan only when a predefined minimum value of a volume flow generated by the fan or a quantity correlating with the volume flow is present.

Abstract: An automatic dishwasher includes a heat pump device for heating washing liquid. The heat pump device includes an evaporator, a fan adapted to supply ambient air to the evaporator, and a device for wet dust collection connected upstream of the evaporator in the flow direction of the ambient air.

Abstract: An automatic dishwasher includes a wash tub, a condensation dryer, and a heat pump device. The wash tub includes a washing compartment, the condensation dryer is adapted to supply outside air to a washtub wall, and the heat pump device is adapted to heat washing liquid. The heat pump device and the condensation dryer have a common fan.

Abstract: A vacuum cleaner includes a housing, a motor-driven suction fan disposed in the housing, a fan motor and a power supply device configured to provide power supply to the fan motor. The vacuum cleaner also includes both a rechargeable battery and cord reel permanently integrated in the housing such that the vacuum cleaner is configured to be alternately operable in a battery mode and a mains mode.

Abstract: A filter includes a filter medium, a filter inlet side, a filter outlet side and an indicator device. The indicator device is configured to be acted upon by air flow through the filter and is disposed adjacent to the filter medium and extends from the filter inlet side to the filter outlet side. The indicator device includes an air path starting from the filter inlet side, a viewing window covering the air path on the filter outlet side, and a flow-through usage indicator configured to receive filtered material and disposed in the air path and visible beneath the viewing window on the filter outlet side.

Abstract: A method for carrying out a dishwashing program in an automatic dishwasher includes a washing step, an intermediate cleaning and a clear rinsing. The washing step includes heating water present in a tub of the dishwasher using at least a condenser of a heat pump. The clear rinsing includes heating water present in the dishwasher tub using the condenser together with an electric heater.

Abstract: Use of moldings with length·width·height dimensions respectively in the range from 1 mm to 3 cm as dust binders in vacuum cleaners, where the molding(s) has/have been produced from chemically untreated open-cell foam whose density is in the range from 5 to 500 kg/m3 and whose average pore diameter is in the range from 1 ?m to 1 mm.

Abstract: Use of moldings whose length·width·height dimensions are always in the range from 1 mm to 5 cm, produced by treatment of (a) open-cell foam whose density is in the range from 5 to 500 kg/m3 and whose average pore diameter is in the range from 1 ?m to 1 mm (b) with an aqueous formulation of at least one cationic polymer (c) and a shaping step, as dust binders in vacuum cleaners.

Abstract: A method for operating a vacuum cleaner having a fan, an electronic control system for the fan and/or another load, and a dust chamber for receiving an air-permeable dust bag, includes providing the dust bag with an identifier, and providing the vacuum cleaner with an identifying device associated with the electronic control system and configured to identify the identifier. When the identifier fails to be identified, at least one of the fan and the other load is controlled using the electronic control system so as to reduce at least one parameter associated with an intake of dust into the dust bag.
