Definitions

  • the invention relates to a method for adapting a washing program in a dishwasher.
  • dishwashing detergent which is in powder form and is introduced into a dishwashing machine dispensing device and dispensed therefrom at a predetermined time
  • liquid rinse aid which is also usually in the door of a dishwasher Present detergent dispenser and introduced therefrom at a predetermined time and in a predetermined amount
  • combination products so-called “2 in 1 tabs” or “2 in 1 gels”, which in addition to the dishwashing detergent also include the rinse aid and "3 in 1 tabs" or “3 in 1 gels”, which are next to the dishwashing detergent Rinse aid also contains a chemical which replaces the function of the softening device.
  • the use of tabs or gels can cause, for example, the rinse aid is released at a time in the wash liquor, at which no rinsing takes place, so that in an actual part program section rinsing no corresponding rinse aid is no longer available. Because with some known tabs or gels the release of the rinse aid is only coupled to the ambient temperature, so if this temperature is exceeded, cleaning, rinse aid is released already during a partial program section.
  • the rinse aid is not activated, so that also no rinse effect is achieved, but the rinse aid after completion of the wash program, for example, still in unresolved form.
  • the rinse aid usually has the function of degrading the surface tension of the rinse aid, the absence of the rinse aid in the rinse liquor leads to a reduced outflow of residual water left on the item to be cleaned in the drying subprogram, which is a significant factor compared to the use of rinse aid liquor with rinse aid portion results in a deteriorated drying result.
  • tabs or gels with a corresponding chemical which replaces the function of the softening device, similarly occurs the disadvantage that the amount of chemicals in the tabs or gels is not adjusted to all degrees of water hardness, so that each regionally, the Use of tabs or gels either reduces the degree of hardness too much or does not sufficiently reduce the degree of hardness.
  • the use of water with insufficiently reduced water hardness leads to a lower effectiveness of the rinsing agent and the rinse aid thereby results in a significantly deteriorated cleaning and drying results.
  • the user of the dishwasher may find that the cleaning performance and / or the drying performance is not satisfactory and in many cases causes this result on the dishwasher, although the cause is mainly due to the use of tabs or gels lies.
  • a composition for using a dishwasher is known.
  • the use includes one of two halves formed body, which forms a cavity in the middle, in which a further active ingredient capsule is stored.
  • a method for operating a dishwasher which may consist of the partial program steps pre-rinsing, cleaning, intermediate rinsing, rinsing and drying, wherein at a reduced degree of contamination a rinsing liquid is hidden and the rinsing liquid is taken over at least in the next program step, for example cleaning.
  • a device for regenerating the softening agent in a washing machine comprising a container for the softening agent, a container for the regenerating salt, and measuring means for determining whether a regeneration process is required. Furthermore, sensor means are provided for detecting the water hardness.
  • a method for the automatic control of the rinsing process in a dishwasher is known in which a depending on the degree of soiling of the items to be washed, the dishwashing amount and optionally of the dishwashing a varied from several part program steps rinsing program is variable.
  • the degree of contamination is preselected by the operator, the program controls depending on the operator's instructions, the Spülprogrammheft occupies and the further course of flushing optionally corrected depending on supplied sensor signals on Spülwassperübung, temperature rise rate and the like.
  • a dishwasher which has a level sensor for regulating the amount of water in a dishwasher.
  • a process for the supply of rinse aid in a dishwasher is known in which by means of an optical sensor, the foam of the final rinse liquid is monitored.
  • the overdosing of rinse aid during the rinsing process is avoided by specifying a desired value for the foam **** in the final rinse liquid for the dosed supply of rinse aid, that the foam detected by the optical sensor during the final rinse cycle is compared in the final rinse liquid with the predetermined setpoint value and the rinse aid is fed continuously or at intervals of the final rinse liquid until the detected *** corresponds to the predetermined desired value.
  • a method for operating a softening device of a domestic dishwasher wherein the softening device comprises an exchanger and a salt reservoir in or on which a sensor device for the latter is arranged as the concentration of a zone located in the salt reservoir, which actuates a display device.
  • the softening device comprises an exchanger and a salt reservoir in or on which a sensor device for the latter is arranged as the concentration of a zone located in the salt reservoir, which actuates a display device.
  • Object of the present invention is therefore to provide a method which allows the Spülprogrammablauf a dishwasher to be adjusted so that even when using a variety of combination detergent satisfactory cleaning and drying performance is achieved.
  • the washing program sequence is adjusted when the absence of the addition of rinse aid and during operation of the dishwasher and / or when the salt is not detected and the softening device is switched off and the dishwasher is operated.
  • the rinse aid failure detection associated with the operation of the dishwasher determines that either the user has forgotten to load rinse aid or that the tabs or gels described are being used. Due to the salt deficiency detection in connection with a deactivated softening device and with the operation of the dishwasher can be determined beyond doubt the use of tabs or gels. In all cases, an adaptation of the washing program is provided without the action of the user to achieve a satisfactory cleaning and drying performance according to the invention.
  • the number of liquor changes in a subprogram step intermediate flushing lowered and / or the number of liquor changes in a partial program step rinse and / or the duration of a partial program step drying and / or the so Connected temperature increased.
  • a reduced number of liquor changes in the sub-program step intermediate rinsing which is usually operated with clear water, allows further use of the cleaning liquor in rinsing, which then - if necessary - this "abducted" fleet can take over the rinsing functions.
  • An elevated temperature of the rinse aid liquor makes it possible to evaporate the residual liquid remaining on the product to be cleaned which has been heated with the rinse aid liquor and thus allows a sufficient drying result.
  • For adequate heating and sufficient residual cleaning of the material to be cleaned also serves to extend the rinse.
  • the increase in the temperature in the rinse also causes an increased temperature in the drying, the extension of which ensures a better evaporation of the residual liquid.
  • the salt water softener is set in operation despite the fact that the softening of the water is deactivated, in the absence of salt during the washing program, and that, if necessary, a salt-deficient indicator is put into operation despite being switched off.
  • the thus enabled use of softened water for cleaning and rinsing a better effectiveness of these additives is achieved.
  • the salt-deficient indicator put into operation despite being switched off indicates to the user the special case in the cleaning act.
  • the lack of consumables is determined by means of a too low level of consumables in an associated reservoir.
  • This usually already existing sensors are used for further advantageous measures.
  • the absence of consumables is determined by means of a sensor for measuring the properties of the corresponding cleaning liquid.
  • the rinse liquor is acidic when rinse aid is added, in contrast to the lye-based detergent liquor.
  • Non-softened water also has a different pH than softened water, in addition to the higher degree of hardness. Therefore, the sensor for measuring the properties of the wash liquor is advantageously a ph value sensor or a water hardness sensor.
  • the concentration of still present rinse aid in the rinse aid liquor can also be determined when compared with a predetermined value. Therefore, in a particularly advantageous manner during the wash program, the number of liquor changes in a partial program step intermediate rinse and / or rinse and / or the duration of a partial program step drying and / or the associated temperature corresponding to the determined. Value adjusted.
  • the softening device despite turned off to soften the water according to the detected value to a minimum value put into operation and possibly a salt deficiency display despite off state in operation. Since it is known that the chemical contained in the tabs or gels, which should replace the function of the softening device acts up to about 25 ° dH, the minimum degree of hardness is intended to be about 25 ° dH.
  • a sensor for measuring the properties of the corresponding cleaning liquid is arranged.
  • the senor for measuring the properties of the corresponding cleaning liquid is a ph value sensor or a water hardness sensor.
