  • the line system forms a substantially closed water circuit with a controllable inlet, a controllable circulating pump and a controllable drain (with drain pump). Part of this water cycle is also a receiving space for the laundry to be cleaned.
  • the detergent drawer usually comprises several chambers for holding various cleaning agents (eg “detergent” and “softener”).
  • the user of the washing machine first pulls out the detergent drawer (eg from a front panel of the washing machine), fills the chambers with the desired amount of detergent or detergents, pushes the detergent drawer back in and starts the operation of the washing machine.

  • the dependent claims relate to advantageous developments of the invention.
  • the basic idea of the invention is to integrate at least one rinsing pump in the area of the drawer for draining and insertable drawer, but to implement the drive largely on the device side and to mechanically couple it to the pump when the detergent drawer is inserted.
  • a particular advantage of the invention is that due to the outsourcing of the actual pump drive, so for example an electric motor, and possibly a transmission, only little space in the detergent drawer is claimed. In the invention, only the pump (s) must be integrated into the detergent drawer.

  • each drawer-side gear is assigned its own device-side and selectively rotatably drivable drive member to separately drive the gears or the respective rinsing pumps associated with the gears.
  • this advantage of a separate driveability of several gears does not necessarily require the arrangement of a corresponding plurality of separately drivable drive members. Rather, measures are conceivable to ensure a selective drivability of multiple gears even if they are in the pushed-in detergent drawer in engagement with the same drive member (or with each other).

Abstract

L'objet de la présente invention est d'obtenir de manière simple sur le plan structural une bonne capacité de dosage du détergent dans un appareil de nettoyage, en particulier un lave-linge ou un lave-vaisselle comportant un tiroir à détergent (22) pouvant être tiré et rentré. A cet effet, au moins une pompe de chasse (32-1, 32-2) est intégrée dans la zone du tiroir à détergent, mais l'entraînement de ladite pompe (32-1, 32-2) s'effectue du côté de l'appareil. L'entraînement de la pompe de chasse (32-1, 32-2) est assuré par un organe d'entraînement (38) pouvant être entraîné en rotation par un moteur et monté sur l'appareil, et par une roue dentée (42-1, 42-2) montée sur le tiroir et se trouvant en coopération avec un arbre d'entraînement de pompe. Lorsque le tiroir à détergent (22) est rentré, la roue dentée se trouve en prise avec l'organe d'entraînement (38) et lorsque le tiroir à détergent (22) est tiré, la roue dentée est libérée de l'organe d'entraînement.
