Definitions

  • the present invention relates to a method for operating a dishwasher, in particular a domestic dishwasher, wherein the method in addition to at least one drying phase further program phases, such as a pre-rinse phase, a cleaning phase and / or an intermediate rinse phase comprises, and wherein the dishwasher a drying device for drying has to be cleaned items to be washed and the functionality of the drying device is monitored at least temporarily.
  • a dishwasher in particular a domestic dishwasher, with a drying device and a control unit for controlling the dishwasher proposed.
  • a rinsing program usually begins with a pre-rinsing phase in which rinsing liquor - usually fresh water in the pre-rinsing phase - is usually not or only slightly heated and by means of one or more spraying in the interior of the washing of the dishwasher on there in one or more dish racks housed items to be sprayed on.
  • the pre-rinse phase is used to remove coarse, easily removable dirt residues from the items to be washed. It usually ends with the pumping out of the dirty Spülflottenexcellent from the washing through a drain pump. This is followed by the actual cleaning phase, possibly with insertion of an intermediate rinsing phase.
  • the rinsing liquor liquid - here usually water - heated to a predetermined temperature and at the same time detergent added to enhance the cleaning effect of the rinsing liquor.
  • the detergent-added water is sprayed by means of one or more sprayers on the items to be washed in one or more dish racks.
  • the polluted water is usually once again pumped out of the washing compartment of the dishwasher by means of the drain pump.
  • the cleaning phase may possibly turn Follow a pregnantphase to using fresh water, which is sprayed through the one or more sprayers in the interior of the washing container, to flush soiling in the region of the bottom sump of the dishwasher and then remove with the aid of a drain pump from the dishwasher.
  • a rinsing phase usually follows, while the heated water mixed with rinse aid is sprayed onto the items to be washed by means of the one or more spray units.
  • This rinsing liquor liquid is pumped out of the interior of the rinsing container by means of the rinse pump at the end of the final rinse phase.
  • the drying phase follows, during which the remaining liquid adhering to the items to be washed evaporates and is removed, for example, by means of a sorption drying unit.
  • the object of the present invention is to propose a method for operating a dishwasher and a corresponding dishwasher, by means of which it is possible to satisfactorily clean the items to be washed even in the case of a (partial) defect of one or more components of the drying apparatus, such as a sorption drying apparatus to be able to dry.
  • the object is achieved in terms of the method in that in case of malfunction of the drying device (which can be stored as needed and in particular for later diagnosis as error message in the memory of the dishwasher by type and time and / or displayed on a display) at least one of Program phases with the help of a control unit skipped, modified and / or replaced by an alternative program phase. In this way, it is ensured that even in the case of a defect or an impairment of the function of the drying device, a clean and dry items to be washed, in particular dishes can be obtained.
  • the dishwasher according to the invention may also comprise other active drying devices.
  • drying devices which bring about active removal of the liquid evaporated in the interior of the dishwasher are conceivable in that the liquid-saturated air is blown or sucked out of the interior, for example with the aid of a blower.
  • Drying devices are also known which comprise heat exchangers, for example in the form of cooling rods or ribs or water-filled water pockets, on which the air moisture condenses inside the dishwasher, in order subsequently to be removed from the dishwasher.
  • an advantageous alternative of the invention provides to skip at least one of the program phases according to the program. For example, it would be conceivable to dispense with an intermediate phase between the cleaning phase and the drying phase if the fan of a sorption drying device does not function properly. In this case, it would be ensured that the items to be warmed up in the cleaning phase also have a relatively high temperature in the drying phase, which ensures evaporation of adhering liquid and thus drying of the items to be washed.
  • the entire program can also be replaced by an alternative rapid program in which a reduced liquid input and thus a smaller amount of rinsing liquor liquid are provided.
  • the lower liquid input finally has the consequence that during the drying phase less liquid must be removed from the items to be washed. For this purpose, it is finally sufficient to heat ware with the aid of heated rinse liquor liquid before the drying phase.
  • the liquid adhering to the items to be washed evaporates, which can finally be condensed and pumped off at the dishwashing space inside walls.
  • a rinse phase only when the malfunction of the drying device occurs or to modify it.
  • active drying devices such as in the case of a Sorptionstrocknungs Surprise
  • the functionality of the drying device is determined directly or indirectly.
  • a direct determination of the functionality means in this context that components of the drying device are monitored. These include, for example, the monitoring of the power consumption of the drying device, in particular a sorption drying device, or individual components thereof (eg a fan or a heater), the detection and evaluation of using one or more appropriate temperature sensors detected temperatures of one or more components of the drying device (eg reversibly dehydratable material of a sorption drying device or a heating device).
  • control components of the respective components of the drying device can also be monitored. If a defect of these control components is detected, then it can be assumed that the drying system is no longer functioning properly.
  • measured values or physical data are monitored, which vary depending on the operation of the drying device. It is thus possible, for example, to determine the presence of water within the drying system with the aid of a water sensor and to compare this value with given standard values. It is also conceivable by monitoring the humidity in the interior the dishwasher to draw a conclusion on the functioning of the drying device. The detection can be done either continuously or at predetermined times, for example, at the beginning of each program phase, after certain time intervals or even once each rinse cycle.
  • One or more moisture sensors in the interior of the dishwasher sensors for measuring the power consumption or the power consumption of the heating device or the fan of a sorption drying device or even temperature sensors can be used for the detection, which detect a defective drying process.
  • the one or more sensors can also cause an alarm or the display of an error message on the display of the dishwasher. It would also be conceivable to evaluate the measured values of several sensors with mutual consideration.
  • the duration of at least one of the program phases is extended or shortened in comparison with the duration when the drying device functions.
  • the cleaning phase could be extended if it is known that the heating device of the sorption drying device, which is also used for heating the rinsing water, no longer works as desired.
  • the heating device of the sorption drying device which is also used for heating the rinsing water
  • the heated air finally comes into contact with the rinsing liquor and the items to be washed and causes the rinsing liquor and ware to heat up. If the heating device of the sorption drying device now has a defect and no longer works at full power, it would be particularly advantageous preferably to extend the cleaning phase accordingly, in order nevertheless to achieve a satisfactory cleaning result. It would also be advantageous to extend the drying phase when the fan of the sorption drying device no longer works as required to ensure reliable drying of the items to be washed.
  • a program phase contains, for example, a specific partial phase during which a desorption of the reversibly dehydratable material is carried out, it would make sense in the event of a failure of the heating device of the sorption drying device to shorten this partial phase in order to keep the overall rinsing program as short as possible.
  • the temperature of a washing liquor circulating through the dishwasher is at least temporarily increased or decreased at least during one of the program phases in comparison to the temperature when the drying device functions.
  • an increase in the temperature of the rinsing liquor during the cleaning phase would make sense if the drying phase is followed by the drying phase and the sorption drying device has a defect.
  • the increased temperature would ensure that the items to be washed and the liquid still adhering after the cleaning phase also have an elevated temperature.
  • this elevated temperature ensures that the liquid can evaporate during the drying phase and condense on corresponding, possibly actively cooled surfaces within the dishwasher (e.g., the sidewalls).
  • At least one of the program phases is run through several times.
  • a double pass of the drying phase can be advantageous, for example, when the drying device can no longer guarantee complete drying in the course of a drying phase.
  • the cleaning phase can also be run through twice if the heating device of the sorption drying device no longer functions as desired and therefore the rinsing liquor can no longer be heated to the required temperature.
  • the individual program phases should always be combined with each other in such a way that despite a malfunction and the associated limited functionality of the drying device, a satisfactory cleaning and drying of the items to be washed can be ensured.
  • the individual program phases in partial phases, for example, a first cleaning phase with a first rinsing liquor temperature and a second cleaning phase with a second rinsing liquor temperature to divide and to let pass through only one of the two phases several times in succession.
  • the drying device is designed as a sorption drying device which, in addition to a reversibly dehydratable material, such as zeolite, comprises a heating device for heating the reversibly dehydratable material and a fan, with the aid of which air moves through the interior of the dishwasher and the sorption drying device can be.
  • a reversibly dehydratable material such as zeolite
  • the sorption drying device allows a particularly energy-efficient and efficient drying, as it comes during the adsorption of liquid on the reversibly dehydratable material to a temperature increase thereof and also the air passed to him.
  • the liquid absorption capacity of the air increases as a result, so that it comes to a fast and almost complete drying of the dishes.
  • the sorption drying device including the heating device and the fan comprises two electrical components that may be subject to malfunction, it is of enormous advantage if the method for operating the dishwasher according to the present invention can be changed. As a result, it is always ensured that the dishwasher has the necessary cleaning and drying performance.
  • the dishwasher comprises an additional water heater, wherein in case of malfunction of the sorption drying device, the water heater is operated to heat the circulating within the dishwasher rinse.
  • the water heater allows the indirect heating of the items to be washed, so that it can come during the drying phase to evaporate adhering to the ware liquid and thus to a drying of the dishes.
  • the water heater also complementary can be operated when the Sorptionstrocknungs Published works properly, it is also possible to operate the water heater only if the Sorptionstrocknungsinnate has a malfunction. Likewise, it would eventually also possible to operate the water heater with an increased heating power, if it is necessary to dispense with the Sorptionstrocknungs announced.
  • an alternative drying phase is activated, while the liquid adhering to the items evaporates by increasing the temperature inside the dishwasher and then on the side walls, the floor and / or the ceiling area of the interior of the dishwasher condensed.
  • a drying phase also referred to as condensation drying, has the advantage that in addition to a water heater, which is optionally provided for heating the rinsing liquor during or the cleaning phase (s), no additional heating means must be present.
  • a heat exchanger is used to support the condensation. Even if there is already without a heat exchanger for a condensation of evaporated liquid in the side walls (which also includes the front door is), since these walls are usually cooled by the ambient air, a heat exchanger has two key advantages. For one thing, the condensation is greatly accelerated, because inside the walls of the heat exchanger, with the air in the interior of the dishwasher come in contact, a liquid (eg fresh water) circulates, which has a substantially lower temperature than the air inside the interior of the dishwasher. On the other hand, the liquid is heated within the heat exchanger. If liquid fresh water from the cold water pipe of a house is used, it can be used as heating water during a subsequent rinse cycle. As this water is already warmed up, there is no need for further heating when the water first comes into contact with the items to be washed. This may for example be the case during a pre-rinse phase.
  • the temperature within the dishwasher is increased before or during the drying phase with the aid of the heating device of the sorption drying device.
  • the sorption drying device as a whole should no longer be functional, since, for example, the reversibly dehydratable material is no longer present in sufficient quantity or because the power of the heating device is no longer sufficient to cause desorption of the reversibly dehydratable material, the sorption drying device serves In this case, still the heating of the air, which flows from the interior through the Sorptionstrocknungs Alpine and back into the interior, and thus causes the heating of the items to be washed and / or the rinsing liquor.
  • the heating device of the sorption drying device is operated at a lower heating power than during the desorption of the reversibly dehydratable material. This may also be useful if the reversibly dehydratable material for whatever reason is no longer able to absorb the necessary amount of liquid for drying. If, in this case, the drying is effected, for example, by the above-mentioned condensation drying, the heating device of the sorption drying device only has to be operated with a lower heating power, which ensures heating of the washing liquor during the cleaning phase or during the evaporation of liquid before or during the drying phase. An additional heating of the reversibly dehydratable material, however, is no longer necessary.
  • the fan of the sorption drying device is operated at an increased speed or reduced speed in comparison with the operation when the drying device functions.
  • the background is that the sorption drying device with a corresponding malfunction no longer the drying of the items to be washed but rather the heating of air, washing liquor and / or dishes has to serve. Since a different contact time with the heated air is necessary here, the volume flow of air through the Sorptionstrocknungs announced can be changed accordingly. Likewise, a change in the fan speed is useful if the heater of Sorptionstrocknungs Published no longer works as desired.
  • the heating device only has half the heating power, then the air should remain longer in the area of the sorption drying device in which the heating device is located so that it can be heated to the required temperature. In this case, it would be advisable to reduce the speed of the fan accordingly. On the other hand, if the heating power of the heating device can no longer be throttled correctly, it would again be advisable to increase the speed in order to prevent overheating of the air and thus damage to the dishes or the dishwasher.
  • the functionality of the drying device by analyzing the functionality of individual components of the drying device, such as a heater and / or a fan, determined and skipped depending on the respective functional capabilities of the individual components at least one of the program phases using a control unit, modified and / or replaced by an alternative program phase.
  • the success of the entire washing program depends not only on the functionality of a single component of the sorption drying device. Rather, it may be that several components do not work as desired. In this case, it is important to consider which process changes are most likely to result in a good cleaning and drying result.
  • the sorption drying device can still be operated. For example, if the heater and the fan each have a slight defect, resulting only in a reduced heating power or a reduced fan speed, it would be possible to extend the duration of the drying phase.
  • the functionality of the drying device is checked before each operation of the dishwasher and only in case of malfunction skipped at least one of the program phases using a control unit, modified or replaced by an alternative program phase.
  • the dishwasher according to the invention which comprises a drying device and a control unit for controlling the dishwasher, is characterized in that it comprises one or more sensors and / or evaluation units, with the aid of which the functionality of the drying device can be determined directly, for example by detecting the power consumption of the drying device. or indirectly, for example by detecting the humidity within the dishwasher, can be determined and that the control unit is adapted to operate the dishwasher by a method in the sense of the preceding description.
  • the selection of the respective change in the program sequence is primarily selected on the basis of data stored in the controller.

  • Conditions eg function OK, function not in order, function restricted
  • possible changes of the wash program are stored.
