Definitions

  • the present invention relates to a dispenser for a washing machine and a washing machine with a dispenser.
  • the dispenser is an important component of a washing machine. On the one hand, it is desirable to be able to fill the dispenser with a powdered detergent and also with a liquid detergent. On the other hand, it should be possible to operate the washing machine in an automatic mode, in which refilling of detergent is only necessary at longer intervals. There is also a desire to make it as easy as possible for the user to load both single wash and multiple wash detergents into the washing machine.
  • the document U.S. 2012/012137 A1 shows a household cleaning implement with a treating chamber and a bulk dispensing system having a removable cartridge configured to hold treating chemistry.
  • a dispenser for a washing machine which has three chambers that extend essentially side by side along a longitudinal extension of the dispenser, with a first chamber of the chambers and a second chamber of the chambers being separated from one another by a first partition and the second Chamber and a third chamber of the chambers are separated from one another by a second partition wall, a first valve being arranged at one end of the first chamber, a second valve being arranged at one end of the second chamber and a third valve being arranged at one end of the third chamber wherein the valves are each adapted to cooperate with a respective connection on the washing machine, wherein a removable cartridge is arranged in the first chamber and the first valve is fixed to the cartridge.
  • a special feature of this dispenser is that the first chamber can contain a special detergent when the cartridge is inserted and a powdered detergent when the cartridge is removed. This enables increased flexibility when using detergents without increasing the requirements for the required installation space.
  • One chamber, preferably several chambers and particularly preferably all chambers can extend from a front area of the induction bowl to a rear area of the induction bowl, ie in particular from a front side of the induction bowl to a rear side of the induction bowl.
  • a sensor is arranged below at least one chamber and a transmitter is arranged within this chamber, so that a filling level within this chamber can be determined by the interaction of the sensor and transmitter.
  • This refinement enables the filling level within a chamber to be reliably determined.
  • several chambers or all chambers of the induction bowl can be equipped with such a combination of sensor and transmitter.
  • the senor is arranged in a depression on the underside of the induction bowl.
  • This refinement enables a particularly space-saving arrangement of the sensor, in which the sensor is also largely protected against possible damage.
  • the senor is in the form of a reed sensor and/or the transmitter is in the form of a float, with the float in particular having a magnet.
  • the reed sensor can determine the level depending on the strength of the detected magnetic field.
  • a first sensor is arranged below the first chamber, a second sensor is arranged below the second chamber, a third sensor is arranged below the third chamber, a first transmitter is arranged inside the first chamber, and a second transmitter is arranged inside the second chamber and within the third, a third encoder is located.
  • This configuration enables the filling level in all three chambers to be measured easily.
  • the transmitter and/or the first transmitter is/are arranged in the cartridge.
  • This configuration is cost-effective, since the sensor only has to be arranged once on the induction bowl, even when using several cartridges, and only the transmitter, which can be structurally very simple and inexpensive, is arranged inside the cartridge.
  • the encoder and/or the first encoder is/are arranged on a guide pin which is essentially perpendicular to the longitudinal extension.
  • This configuration is particularly cost-effective since the guide pin on the one hand ensures reliable guidance of the encoder or the first encoder and on the other hand can be manufactured easily, in particular using the injection molding process.
  • a constriction element is arranged inside the cartridge, which restricts a flow of a fluid inside the cartridge along the longitudinal extension.
  • This configuration prevents or reduces sloshing of the fluid within the cartridge, ie for example a liquid detergent in the cartridge. Such sloshing can otherwise occur, for example, when the user pulls the dispenser out of the washing machine.
  • the narrowing element has a wall element which is arranged approximately perpendicular to the longitudinal extension and narrows the cross section of the cartridge perpendicular to the longitudinal extension for the fluid.
  • the constriction element has two parts which protrude approximately perpendicularly to the longitudinal extent of two opposite walls of the cartridge, are spaced apart from one another along the longitudinal extent and in particular overlap one another when viewed along the longitudinal extent.
  • This configuration of the constriction element is technically easy to implement and particularly effective. Despite an effective reduction or prevention of sloshing, it is ensured that the user can fill the cartridge as usual and that there is no back pressure.
  • the induction bowl has a sensor unit which checks the presence of the cartridge and the correct seating of the cartridge.
  • This configuration ensures that the washing operation with the cartridge is possible without any problems.
  • the sensor unit has a first sensor element that checks the presence of the cartridge and a second sensor element that checks the correct seating of the cartridge, the first sensor element being spaced apart from the second sensor element along the longitudinal extent.
  • the first sensor element is positioned further forward with respect to the longitudinal extent than the second sensor element. If the first sensor element does not detect the presence of the cartridge, an operating mode without a cartridge is activated, in particular an operating mode with powdered detergent. If the first sensor element detects the presence of the cartridge and the second sensor element detects that the cartridge is seated correctly, an operating mode with a cartridge is activated, in particular an operating mode with a special detergent.
  • the user is informed that the operating mode with cartridge appears to be desired, but the seating of the cartridge does not yet permit this.
  • the first sensing element does not detect the presence of the cartridge but the second sensing element does detect that the cartridge is properly seated, the user is alerted to a problem with the sensing elements.
  • a base of a chamber located at the edge of the induction bowl rises perpendicular to the longitudinal extension and reduces the height of this chamber towards the edge.
  • the dispenser can be higher on a first side, which is oriented toward an outside of the washing machine, than on a second side, which is oriented toward the inside of the washing machine, since the washing drum is located here. It is therefore not necessary for an increased volume to increase the overall height of the washing machine.
  • a partition is arranged in a chamber into which no liquid in the chamber flows, which is open at the top and can accommodate a locking tongue arranged in an upper side of the induction bowl when this is pressed in the direction of an underside of the induction bowl .
  • the latching tongue is arranged in such a way that when the dispenser is pulled out, it initially releases it only to the extent that a user can refill detergent. If the user depresses the tongue, the dispenser is unlocked and can be pulled completely out of the washing machine. Due to the chamber arranged below the latching tongue, the latching tongue can be designed in a structurally simple manner, since sealing with respect to the chamber takes place by means of the partition.
  • the partition is preferably designed as a wall element which, in a plan view from above, is in particular U-shaped.
  • the first partition has a first course, a first transverse course and a further first course, the first course beginning in a front region of the induction bowl, extending essentially along the longitudinal extent and merging into the first transverse course, the first Transverse course extends at an angle to the longitudinal extension and merges into the further first course, and the further first course extends essentially along the longitudinal extension and ends in a rear area of the dispenser.
  • the first transverse course also serves as a protection against sloshing.
  • the first course and/or the first transverse course and/or the further first course are, in particular, at least substantially rectilinear. Furthermore, it is advantageous if the first transverse course is formed at least approximately perpendicularly to the first course and/or to the further first course.
  • the second partition wall has a second course, a second transverse course and a further second course, the first course beginning in a front region of the induction bowl, extending essentially along the longitudinal extent and merging into the second transverse course, the second The transverse course extends at an angle to the longitudinal dimension and merges into the further second course, and the further second course extends substantially along the longitudinal dimension.
  • This configuration makes it possible in a simple manner to simplify access to the second chamber for filling in a detergent if the second chamber is to be made smaller than the third chamber.
  • the second chamber may be desirable for the second chamber to have a volume which is less than 85%, preferably less than 75%, particularly preferably less than 65% and in particular less than 55% of a volume of the third chamber.
  • the second chamber could then be narrow. Due to the widening caused by the second transverse course, the second chamber can be filled well even with a small volume.
  • the second transverse course also serves as a protection against sloshing.
  • the second course and/or the second transverse course and/or the further second course are, in particular, at least substantially rectilinear. Furthermore, it is advantageous if the second transverse course is formed at least approximately perpendicularly to the second course and/or to the further second course.
  • the second partition wall has a further second course, a further second transverse course and a further second course, the second course extending essentially along the longitudinal extension and merging into the further second transverse course, the further second transverse course itself extends at an angle to the longitudinal extension and merges into the further, second course, and the yet further, second course extends essentially along the longitudinal extension and ends in a rear area of the dispenser.
  • This configuration makes it possible to implement the arrangement of a third valve for the third chamber in a simple manner. This applies in particular when a bottom of the third chamber rises perpendicularly to the longitudinal extension and thus reduces the height of this third chamber towards the edge.
  • the third valve can still be arranged at least approximately at the level of a second valve of the second chamber and/or a first valve of the first chamber.
  • the further second transverse course also serves as a protection against sloshing.
  • the further second course and/or the further second transverse course and/or the yet further second course are, in particular, at least substantially rectilinear. Furthermore, it is advantageous if the further second transverse course is formed at least approximately perpendicularly to the further second course and/or to the further second course.
  • a water shower is arranged above the first chamber, which is designed to flush water into the first chamber.
  • This configuration makes it possible in a simple manner to mix a powdered detergent located in the first chamber with water and to flush it out of the first chamber.
  • the first chamber has an opening on the underside, from which a liquid in the chamber can emerge downwards.
  • This configuration makes it possible in a simple manner to rinse a powdered detergent which is in the first chamber and has been mixed with water out of the first chamber and remove it from the dispensing compartment, in particular in the direction of a washing drum of the washing machine.
  • the cartridge has a screw cap.
  • This configuration enables the cartridge to be closed securely, but at the same time it is possible to easily refill the cartridge. Due to the screw cap, no special liquid detergent can be spilled when the cartridge is handled by the user.
  • a second cartridge is arranged in the second chamber and the second valve is arranged in the second cartridge.
  • a third cartridge is arranged in the third chamber and the third valve is arranged in the third cartridge.
  • the object is also achieved by a washing machine with a flushing-in bowl as described above.
  • Such a washing machine is particularly easy for a user to operate and enables the washing machine to function reliably.
