Definitions

  • the invention relates to a dishwasher according to the preamble of the first claim.
  • a metering device for at least one additive is integrated into this door, by means of which at least one additive such as cleaning agent or rinse aid is metered into the washing liquid intended for cleaning dirty dishes in a program-controlled manner.
  • the dispensing device of the metering device is directed into the working container.
  • such metering devices are provided with a chamber for the manual addition of the powdered cleaning agent required for a rinse cycle, the chamber being provided with a program-controlled flap which is opened under program control at the start of the cleaning rinse cycle, so that the powdered detergent falls into the working container or from which the rinsing liquid distributed by means of spray devices is rinsed out.
  • a program-controlled flap which is opened under program control at the start of the cleaning rinse cycle, so that the powdered detergent falls into the working container or from which the rinsing liquid distributed by means of spray devices is rinsed out.
  • you can also use it Detergent in tablet form and in the amount measured for a rinse cycle and fall out or be rinsed out according to the program. (DE 35 41 145 A1).
  • the disadvantage of this design is that the metering device for solid detergents must be manually loaded with the amount of detergent dimensioned for the relevant dishwashing process.
  • the invention has for its object to take measures in a dishwasher according to the preamble of the first claim, by means of which the cleaning agent can be stored and metered out for several rinse cycles.
  • detergent tablets in an amount sufficient for several complete dishwasher program sequences are manually introduced into a storage container, from which, by means of an assigned dosing device, only the number of tablets required for the respective dishwashing program sequence are separated from the supply and according to the program the respective washing program section is output.
  • One or more tablets can be dispensed into the rinsing liquid per rinse cycle, the amount being dependent on the water hardness, the degree of contamination of the rinsing liquid or the like.
  • the metering device is preferably detached from the door closing the working container inside the Working container arranged and coupled to control means, wherein part of the necessary control means is associated with the dosing device and the other part of the control means is arranged outside the working container, both parts of the control means being coupled to one another in order to transmit drive and / or control signals for the dosing device.
  • the coupling can be done purely wireless, for which radio and / or ultrasound and / or light energy are suitable or capacitive or inductive coupling by means of a divided AC transformer is possible. The energy required for the mechanical drive and possibly also a control signal can be transmitted via this coupling.
  • the metering device can be equipped with an electrical energy store which stores small electrical energy transmitted by the wireless supply and feeds the metering device only after a control signal has occurred.
  • mechanical control means can also be provided, which are actuated by a drive device arranged outside the working container and which transmit the mechanical forces necessary for actuating the metering device to the metering mechanism.
  • the dosing device can be attached to a crockery basket, where it is freely accessible in a particularly simple manner by pulling it out when tablets are to be refilled or the tablet supply is to be checked.
  • the metering device is in particular detachably attached in order to be able to carry out any necessary repairs or cleaning operations on it in a simple manner.
  • the metering device can also be attached to a wall of the working container, with the advantage here that the coupling means are then close to one another can be arranged and a reliable energy transfer is possible.
  • a small distance between the coupling means is particularly advantageous in the case of inductive or capacitive coupling.
  • the solvability is also given in this case.
  • the base of the working container below the lower crockery basket in the corner area is suitable as the attachment point for the dosing device, where the rotating spray arm is not sufficient and the space available for receiving items to be washed is not impaired.
  • inductive coupling it is expedient to provide a divided AC-fed coil of an electrical transformer, one coil of which can be fitted in the metering device and the other in the working container or outside the same in the case of a non-magnetic container wall. It is possible to transmit the energy transmission like the control signals via a coil set if separate signals are required for this. However, it is also possible to provide two or more sets of coils via which different electrical signals can be transmitted if necessary.
  • a metering device 1 comprises a lockable storage container for tablet-shaped cleaning agent to be loaded and an associated metering device with control means for the controlled dispensing of one or more tablets during a pre-rinse or cleaning cycle in the program sequence of a dishwasher.
  • the part of the control means assigned to the dosing device 1 is arranged with the further part of the control means necessary for the control outside the working container of the dishwasher and is preferably wirelessly coupled to the first part of the control means in the dosing device.
  • the wireless coupling is particularly suitable when the dosing device 1 is preferably detachably assigned to a crockery basket 2 that can be at least partially moved out of the working container.
  • a wired coupling line is possible if the dosing device 1 according to FIG.
  • the metering device 1 is preferably arranged on the bottom of the working container in the region of a corner, to which a rotatably mounted spray arm is not sufficient. There is then no space for accommodating items to be washed in the crockery basket 2 and the function of the spray arm is not affected.
  • the arrangement of the metering device 1 in the corner area near the door then allows good accessibility when the lower crockery basket 2 is extended onto the door.
  • the metering device 1 can also be used the underside of the crockery basket 2 can also be detachable and, if necessary, set at a distance, so that in this area of the crockery basket 2 at least those items to be washed can be placed that do not or only slightly stand down by bars of the crockery basket 2.
  • This type of attachment is also advantageous if the coupling of the control means takes place optically, inductively or capacitively, because then the dosing device is arranged in such a way that it can be brought close to the adjacent side wall of the working container with the couplers of the control means assigned to it corresponding coupling means of the other control part carries.
  • the dispensing device 1 can then preferably be arranged on the upper basket of a dishwasher, the associated spray arm of which is supplied with washing liquid by means of a support tube 3 fed with washing liquid and which is passed through a side wall of the working container and carries and feeds the necessary spray arm below the dish basket.
