Definitions

  • the problem addressed by the invention is thus to provide a method for operating a washing machine and a washing machine in which a plurality of detergent components can be mixed in the washing machine.
  • the invention relates to a method for operating a washing machine with a tub for receiving washing liquid and a circulating device having a circulating pump for conveying the washing liquid from a first area of the tub into a second area of the tub, in which at least two detergent components are composed of one or more Dosing devices are fed into the circulation pump in a predetermined dosage, and in which the circulation pump is operated during and / or after the at least two detergent components are fed in at a speed below a delivery speed at which the washing liquid from the first area of the tub in the second area of the tub is promoted, and in which the circulation pump is then operated at a speed equal to or above the delivery speed.
  • a mixing process is effected, and by operating the circulating pump at a speed equal to or above the delivery speed, a flooding process is achieved.
  • the mixing chamber can be rinsed during the circulating process and the detergent solution can be safely introduced into the laundry.
  • the concentrated mixture obtained can be introduced into the laundry by operating the circulating pump at a speed equal to or above the delivery speed and advantageously diluted with washing liquid in the tub, such as water, to generate an application solution that is introduced into the laundry.
  • the connection of the metering point to the circulation pump has the further advantage that the metering point is connected to a non-vibrating component and fixed, diffusion-tight piping is possible.
  • the water inlet is preferably activated before the detergent components are fed in, so that washing liquid is filled into the tub in the form of water.
  • This embodiment enables the mixing of concentrated detergent components to increase the yield of active substances such as e.g. Bleach and subsequent dilution to generate an application solution or wash liquor and introduction of the application solution into the laundry, since when the circulating pump is operated at a speed equal to or greater than the delivery speed, the washing liquid in the tub is compared with that when the circulating pump is operated at a speed below the Delivery speed generated detergent component mixture is mixed. Thinning can prevent the laundry from being exposed to a high concentration of detergent.
  • washing liquid located in the tub is conveyed in the form of water through the circulation device from the first area of the tub to the second area of the tub.
  • the pumping is preferably ended when the at least two detergent components are started to be fed into the circulation pump. It can thereby be achieved that the circulation pump contains as little washing liquid as possible in the form of water while the washing agent components are being fed in.
  • concentrated detergent components can be mixed.
  • the concentrated detergent-component mixture obtained can then be diluted by operating the circulating pump at a speed equal to or above the delivery speed and thus an application solution can be generated which is introduced into the laundry.
  • the detergent components are fed into a suction area of the circulation pump.
  • the circulation pump is activated in this embodiment of the method and is operated at a speed below the delivery speed. After the detergent components have been mixed in the circulation pump, the circulation pump is operated at a speed equal to or above the delivery speed and conveys the detergent-component mixture into the second area of the tub.
  • the detergent-component mixture is preferably sprayed directly onto the laundry so that a short path to the point of action of the detergent-component mixture is possible.
  • the control or regulating device preferably controls or regulates an activity of the circulation pump.
  • the control or regulating device is preferably designed to control or regulate its speed when the circulating pump is activated, so that the speed is below the delivery speed or equal to or higher than the delivery speed, depending on requirements. That is, the control or regulating device is preferably designed to control or regulate the circulation pump in such a way that it can function as a mixing chamber or conveying device for conveying washing liquid from the first area of the tub to the second area of the tub, as required.
  • the control or regulating device is preferably set up to control or regulate an operation of the circulation pump in a method in accordance with one or more of the embodiments described above.
  • the circulation pump has two, three or four circulation suction nozzles for connection to the metering device or devices for the detergent components.
  • the washing machine is designed so that two, three or four detergent components can be fed into the circulation pump simultaneously and / or one after the other.
  • the first area of the tub is preferably the lower region of the tub, and the second region of the tub is preferably the upper region of the tub, based on the operational position of the washing machine.
  • the detergent-component mixture is therefore preferably applied from above to the laundry in the drum.
  • Each metering device preferably has an automatic metering unit.
  • the metering device is connected to the washing machine via at least one metering line.
  • Each detergent component is fed through the at least one metering line from the metering unit into the flooding device in a predetermined dosage.
  • the dosage can be set manually on the dosing device or controlled by selecting a washing program on the washing machine.
  • the metering device is preferably designed separately from the washing machine.
  • At least one metering line is mounted on the metering device and in each case on the at least one bypass suction nozzle.
  • the dosing line connects the dosing device directly with the flooding device.
  • the metering device can have several chambers for receiving one detergent component each. Alternatively or additionally, a separate metering device can be provided for each detergent component.
  • the washing machine can be a household appliance or a commercially used appliance.
  • the term "washing machine” also includes combination devices such as a washer-dryer.
  • the detergent components are preferably liquid components.
  • a detergent component can have one or more ingredients.
  • One constituent can be inert or reactive to other constituents of a further detergent component.
