Definitions

  • the invention relates to a method for cleaning a metering device of a water-conducting household appliance, in particular a laundry treatment appliance for washing and / or drying laundry. Specifically, the invention relates to the field of washing machines and washer-dryers.
  • a method for cleaning dosing lines in automatically controlled laundry treating machines and a laundry treating machine operating according to such a method are known.
  • flowable laundry treatment means are supplied by means of an automatic dosing of at least one reservoir by means of a metering pump in machine-sized doses via a dosing to a laundry treatment process.
  • such a dosing line is rinsed after the introduction of a dose for cleaning by means of a rinsing agent.
  • residues of such rinsing agents which have diluted residues of laundry treatment agents, do not germinate on prolonged dwelling in the dosing lines, the dosing lines are rinsed immediately before delivering a dose.
  • DE 10 2008 040 647 A1 discloses a further water-conducting household appliance, in particular in the form of a dishwasher, which is set up for carrying out a cleaning program of the washing compartment.
  • the object of the invention is to provide a method for cleaning a metering device of a water-conducting household appliance, wherein the operability is improved. Specifically, it is an object of the invention to provide a method for cleaning a dosing device of a water-bearing domestic appliance, in which a reliable operation is ensured and a manual cleaning to be performed by the user is simplified.
  • the object is achieved by a method for cleaning a metering device (16) of a water-conducting domestic appliance, in particular a laundry treatment appliance for washing and / or drying laundry, in which at least one storage container, which serves to receive at least one liquid treatment agent, one driven by an electric motor Dosing pump and a controller are provided which serves to drive the electric motor of the metering pump, wherein the controller controls the electric motor of the metering pump in a normal mode so that the metering pump promotes the liquid treatment agent from the reservoir into a treatment area, and wherein the control of the electric motor Dosing pump in a cleaning mode at least temporarily controls so that the electric motor generates a relation to the normal mode increased torque and / or a varying torque for driving the metering pump.
  • an automatic dosing system for textile treatment agents or other liquid treatment agents can be ensured.
  • treatment agent residues which occur in particular in the event of prolonged disuse in the area of the metering pump can be eliminated.
  • automatic dosing systems With prolonged storage and adverse environmental conditions, such as at elevated temperature or aerated liquid surface, automatic dosing systems have the problem of drying or gelling the ingredients of the liquid processing agent. Depending on the design of the dosing system, this may mean that the user must disassemble and clean the system manually to ensure functionality and to ensure a clean, hygienic condition.
  • the automatic dosing usually consists of a variety of components, for example, in addition to the reservoir from connecting hoses or the like, which are connected to the reservoir and / or the metering pump. With such components, the cleaning can be very complicated.
  • such components are not accessible to the user as they are mounted within the housing of the water-bearing household appliance and thus are not accessible to the user.
  • the control allows automatic or semi-automatic cleaning of one or more components of the dosing system in the cleaning mode. Especially in the area of the metering pump, it can lead to encrustations or buildup due to contamination. Furthermore, lines can also be affected, which lead from the reservoir to the metering pump or from the metering pump in the treatment area.
  • By driving the electric motor with an increased torque and / or a varying torque for driving the metering pump during the cleaning mode such contamination can be solved.
  • a functionality of the metering pump can be restored if it is added or blocked.
  • a high reliability of the water-bearing household appliance can be ensured in an advantageous manner and carried out a cleaning of the dosing.
  • the electric motor is designed as a DC motor and that the controller controls the electric motor in the cleaning mode at least temporarily with a higher and / or pulsed voltage.
  • the electric motor of the metering pump is operated, for example, substantially permanently with an unregulated or regulated voltage. This voltage in normal operation is in a specified for the electric motor rated voltage range.
  • the metering pump can no longer be controlled permanently, but pulsed, with a voltage well above the normal operating voltage can be used. In this way, an increased torque of the electric motor can be achieved, which serves as a breakaway torque for breakaway in a blocked engine. This higher torque helps to dissolve adhering encrustations.
  • possibly adhering particles or the like in this mode learn each higher rotational momentum and thus with the same geometry of the metering pump higher centrifugal forces, which promotes the detachment of the adhering particles or the like.
  • the controller in the cleaning mode activates the electric motor of the metering pump, at least temporarily, for pumping through the metering pump a solvent provided in the reservoir instead of the treatment agent.
  • the control in the cleaning mode when pumping the solvent through the metering pump at least temporarily actuated a valve to pump the solvent via the metering pump back into the reservoir.
  • a user may transfer any remaining liquid processing agent from the reservoir to a storage vessel or the like for further use.
  • the reservoir is preferably accessible to the user in a simple manner and can be pulled out of the housing, for example. The user can thus manually clean the reservoir with relatively little effort.
  • a rough cleaning of the reservoir can be done by rinsing with a shower or the like.
  • the user can fill a certain amount of a solvent, in particular water, in the reservoir.
  • the filled with the solvent reservoir can be used in the usual way in the housing.
  • the metering pump now sucks in the solvent from the storage container instead of the liquid treatment agent.
  • the metering pump is flushed through together with further elements of the laundry treatment appliance.
  • the solvent is pumped through the metering pump back into the storage container, there is the advantage that the cleaning process can be carried out for a longer period without the solvent having to be topped up. In particular, several cleaning cycles can be run through.
  • detached incrustations, particles, lumps of dirt or the like which are transported by the solvent, reach the storage container and thus can be disposed of directly by the user. The user can thereby also see the success of the cleaning program.
  • one or more lines are provided, through which the liquid treatment agent is conducted from the reservoir via the metering pump in the treatment area in the normal mode, and that the lines are at least substantially flushed by the solvent in the cleaning mode. This can be done a substantial cleaning of the dosing.
  • the controller for performing the cleaning mode indicates to a user that the reservoir is to be filled with a solvent. This allows a user-friendly operation and a reliable performance of the cleaning of the dosing.
  • the controller detects a clogging or blocking of the pump and that the controller controls the cleaning mode when the pump clogs or blocks or offers the user the execution of the cleaning mode.
  • the control activates or offers the cleaning mode only after termination or outside the normal operating mode. For example, clogging or blocking of the electric motor can be detected via the energy consumption of the electric motor. In this way, a timely execution of the cleaning mode and thus a reliable operation over the life of the water-bearing household appliance can be ensured in an advantageous manner.
