Definitions

  • the invention relates to a system for cleaning dishes.
  • the invention also relates to a method of cleaning dishes using such a system.
  • a dishwashing machine which is adapted to the use of combination preparations in that a sensor is provided, with which the presence of the combination preparation, usually a so-called tab, is detectable.
  • a sensor is provided, with which the presence of the combination preparation, usually a so-called tab, is detectable.
  • acoustic, optical, thermal or pneumatic sensors or sensors with which changes in the wash liquor with respect to the pH, temperature, turbidity, foaming or concentration are detectable. It is disadvantageous that with the first sensor group very different types of tabs are distinguishable and the measurement results of the second sensor group are easily distorted by the staining of the dishes.
  • the DE 20115173 U1 describes a dishwasher, which recognizes the type of Spülzusatzes by identification marks on Spülzusatz containers. Such containers are usually used only in commercial dishwashers, because only these are equipped with the required metering pumps.
  • the DE 10260144 A1 discloses a domestic appliance with a control device and a metering device to be placed in the washing container, which communicate with each other in a radio-based manner.
  • the DE 102008027284 A1 describes a dosing device for a household appliance, with a designated for whereabouts at a specified location in the washing compartment console and a recordable in the console removable unit in which the detergent is included or fillable.
  • the metering device can also communicate with the household appliance by radio.
  • the inventive system for cleaning dishes consists of a dishwasher with a rinsing container and with a control device having a sensor for detecting a property of a rinsing additive, and from a metering device comprising a magazine from which a number of rinse additive portions successively in the Rinsing can be dosed.
  • a control device having a sensor for detecting a property of a rinsing additive, and from a metering device comprising a magazine from which a number of rinse additive portions successively in the Rinsing can be dosed.
  • an encoder is arranged or can be arranged on the magazine, with which an identifiable by the controller signal of the sensor can be triggered and in the washing and / or on the magazine holding means are arranged, through which the encoder can be brought into a defined position to the sensor. This ensures that the sensor cooperating with the controller is always able to reliably recognize the inserted magazine and accordingly to adapt the further program sequence.
  • control device with the sensor is arranged in a door which closes an opening on the front side of the washing container.
  • holding means are arranged on the door.
  • holding means are arranged on a dishwashing basket arranged in the washing container, preferably on its side adjacent to the door.
  • the encoder is fastened or attachable to a cover arranged on the magazine.
  • the opening of the lid can be easily detected by the fact that the signal flow is interrupted by the encoder to the sensor.
  • the controller can detect in this way that the magazine is refilled and react accordingly.
  • the lid is a place easily accessible to the user. For example, he can easily attach a donor supplied with the dishwasher to a designated place.
  • Another object of the invention is a method for cleaning dishes, which makes use of the system described above and is set in accordance with the control of the dishwasher in motion.
  • the controller recognizes the filling of the magazine from the sensor signal and activates an optical or acoustic level indicator. The user thus knows when the magazine is empty and refilling is necessary. Alternatively or additionally, the remaining supply of rinse additive portions can be displayed.
  • the recognition of the filling can, as described above, by the opening of the lid and the associated interruption of the signal flow be implemented by the encoder to the sensor. This is particularly easy if the magazine is attached to the door and the encoder always has the same distance to the sensor. Otherwise, appropriate measures must be taken in the area of the encoder, which generate a signal change when the cover is removed.
  • FIG. 1 shows the inventive system 1 in the form of a schematic diagram.
  • a side wall is removed and thus a view of the interior of the washing container 3 is possible.
  • two baskets, an upper basket 4 and a lower basket 5, in pull-out (not shown) from the container 3 are arranged in a known manner.
  • the baskets 4 and 5 are used to hold items to be washed (not shown), which irrigates with the aid of associated spray arms 6 and 7 with rinsing liquid and thereby can be cleaned.
  • the rinsing container 3 has on its front side an opening 8, which is closable by a door 9 pivotally mounted in the lower region.
  • the door 9 is constructed of an outer panel 10 and an inner panel 11 connected at the edges.
  • the lower part 24 is provided with a hook 25 which can be suspended in a strut 26.
  • the strut 26 may be part of one of the baskets 4 or 5, preferably the upper basket 4. It is particularly advantageous if the strut 26 is arranged on the side adjacent to the door of the dish rack.
  • FIGS. 3 and 4 show other possible holding means, so shows FIG. 3 an annular holder 27 and FIG. 4 a backdrop 28 with a matching counterpart 29.
  • the magazine 21 be an integral part of the dishwasher 2, in which the lower part 24 is attached either to a dish rack 4 or 5 or to the door 9.
  • Die FIG. 5 shows the simplest encoder-sensor combination in the form of a magnetic encoder 301 on the magazine cover 23 and an inductive sensor 311 in the door.
  • FIG. 6 FIG. 12 shows an encoder 302 having a design shape identifiable by an optical sensor 312.
  • simple graphic patterns such as barcodes o. ⁇ . Conceivable, but also holograms and the like.
  • Alternative donor-sensor combinations not shown in the drawings are mechanically constructed or use RFID.
  • the encoders 30 may also be arranged on at least one of the rinse additive portions 22 itself. If different types of rinse additives are offered, the transmitter 30 can then also convey information about the respective type of rinse additive 22 that has been stored in a magazine. For this purpose, this information, for example in the form of a bar code (not shown) may be printed on the rinse additive portions 22 and detected by a window in the magazine by the optical sensor. Such an option is also possible if the encoder 30 is indeed arranged on the magazine 21, but can be influenced in such a way that the signal generated at the sensor 31 also depends on the type of flushing additive 22. Instead of a fixed arrangement on the magazine 21 or the rinse additive 22 and a donor 30 is conceivable, which is supplied with the dishwasher 2 and is then attached by the user on the magazine 21 or the rinse additive 22 at a designated location.
  • the device control 13 can detect the removal of the magazine lid 23 when the sensor signal is interrupted. If then a renewed approach of the lid 23 is sensed, the device controller 13 can conclude that the magazine 21 has been filled. Subsequently, it can calculate the fill level of the magazine 21 by counting the processed programs and activate a corresponding optical or acoustic level indicator, for example in the display 18. As a result, the user can be informed in good time of a need to refill the magazine 21.
  • the usual turbidity measurement is not carried out after approx. 10 minutes of water circulation in order to decide whether the water should be changed in the event of severe turbidity or otherwise used. This decision would be falsified by the previously solved amount of cleaners, because this produces a cloudiness. Instead, the turbidity is measured after only 1-2 minutes of water circulation, and the decision on a water change is made on the basis of another, lower threshold value.
  • a quick program is selected, the customer is shown on the display 18 that the magazined cleaning agent does not match the program because it does not dissolve quickly enough.
  • the program duration in the cleaning program section is extended so that the cleaner can dissolve completely and is not dragged into the rinse cycle and produces very unsightly deposits on the items to be washed.
  • a program start can be suppressed and the user can be prompted to redial a suitable program.
  • the from the WO 2008/145967 A1 and the WO 2008/053191 known metering device 20 detects the implementation of a new program and the associated need for a new dosage by the temperature difference of hot (when circulating the heated rinsing liquor during the program flow) too cold (after the program end). If very cold water is used in the intermediate rinsing, the second water inlet, where the appliance has already cooled down, can cause a second, unwanted dosing due to the strong cooling. This can be prevented.
  • the necessary program changes may then consist in a suppression of a second intermediate rinse program section, a shortening of the intermediate rinse program sections or a heating in the intermediate rinse program sections.
