Definitions

  • the invention relates to a dishwasher with a sorption drier.
  • the invention also relates to a method for operating a dishwasher with at least one partial programme step with rinsing liquor that is to be heated to a nominal temperature, e.g. “Clean”, wherein air that is heated in this partial programme step by a heating device and is used for desorption of a reversibly dehydratable material and/or ambient air is conducted from a rinsing container of the dishwasher by a sorption column with reversibly dehydratable material into the rinsing container in order to heat the rinsing liquor and/or items to be washed.
  • a nominal temperature e.g. “Clean”
  • conventional dishwashers have a washing process whose programme sequence generally consists of at least one “Prewash” partial programme step, a “Clean” partial programme step, at least one “Intermediate Wash” partial programme step, a “Clear Wash” partial programme step and a “Drying” partial programme step.
  • the rinsing liquor is in this case heated before or during a partial programme step.
  • the rinsing liquor is normally heated by means of electric heating devices.
  • Different drying systems are known for drying the items to be washed in a dishwasher.
  • a dishwasher of the type just mentioned is disclosed in DE 20 16 831, in which the air is conducted from the rinsing container via a sealable opening in the wall of the rinsing container on reversibly dehydratable material and from there via an opening to the outside.
  • the desorption of the reversibly dehydratable material takes place during the non-operating phase of the dishwasher, the water vapour formed thereby being conducted to the outside via the opening.
  • the dishwasher described is disadvantageous from the energy viewpoint because the regeneration of the reversibly dehydratable material takes place during a non-operating phase of the dishwasher, i.e. at a time when none of the partial programme steps already described is being carried out.
  • a further disadvantage consists in the fact that the possibility of damage to the surrounding kitchen furniture cannot be ruled out because of the discharge of the water vapour formed during the regeneration of the reversibly dehydratable material to the outside.
  • the regeneration is associated with an additional energy requirement which is added to the energy required during the partial programme steps.
  • DE 103 53 774.0 of the applicant discloses a dishwasher with a rinsing container and devices for washing dishes by means of rinsing liquor, which dishwasher has a sorption column connected in an air-conducting manner to the rinsing container and containing reversibly dehydratable material, wherein on the one hand the sorption column is used to dry the dishes and on the other hand the thermal energy used for desorption of the sorption column is at least partially used for heating the rinsing liquor and/or the dishes.
  • Heating of the items to be processed is normally no longer necessary in the partial programme step preceding the “Drying” partial programme step due to the use of reversibly dehydratable material with a hygroscopic property, e.g. zeolith. This allows a considerable energy saving.
  • EP 0 358 279 B1 discloses a device for drying dishes in a domestic dishwasher in which the rinsing liquor is heated by a heater arranged outside the rinsing container, preferably an electric geyser, a largely closed drying system being provided here in which air circulates from the rinsing container via a drying device that can be regenerated by heating and from this device back into the rinsing container.
  • the drying device consists of a drying container in thermal contact with the heater, which container is filled with a drying means adsorbing the moisture. Because the drying container is connected to the heater provided in any case for heating the rinsing liquor, the drying device is immediately operational after completion of the rinsing process.
  • the drying means is in this case placed at least partially around the heating elements as a jacket so that the drying means can be heated and hence dried in the drying container during each heating process.
  • the drying container is designed as a double-wall hollow cylinder into which the drying material is introduced.
  • the inlet and outlet opening for connection to the closed air system are arranged diagonally opposite one another.
  • the disadvantage of this is that it gives rise to a relatively flow resistance, with the result that the fan provided for conveying the air flow must be operated at very high power. This has a negative effect in terms of noise development and energy consumption.
  • the desorption is time consuming and may also lead to local overheating of the drying means and hence to its irreversible damage.
  • the desorption is also difficult because the heater is arrange din the centre of the double-wall hollow cylinder and radial distribution of heat to the drying means close to the outer hollow cylinder wall is hardly possible because of the air flowing axially past it.
  • the object of this invention is therefore to provide a method for operating a dishwasher and a dishwasher, particularly a domestic dishwasher, with which it is possible to shorten the length of a rinsing programme with a plurality of partial programme steps.
  • a dishwasher in particular a domestic dishwasher
  • at least one partial program step with rinsing liquor that can be heated to a nominal temperature e.g. “Clean”
  • a heating device for desorption of a reversibly dehydratable material is conducted from a rinsing container of the dishwasher and/or ambient air is conducted through a sorption column with reversibly dehydratable material into the rinsing container for heating the rinsing liquor and/or the items to be washed
  • the heating device continues to operate after a desorbed condition of the reversibly dehydratable material is attained until the nominal temperature of the rinsing liquor is reached.
  • the term desorbed condition of the reversibly dehydratable material is understood in this invention to mean that the reversibly dehydratable material is completely or almost completely dehumidified.
  • the rinsing liquor is not heated by a conventionally designed (water) heating device but that the energy expended for the desorption is used during a partial programme step with rinsing liquor to be heated for heating the rinsing liquor.
  • desorption is normally fully completed at a time when the rinsing liquor has no yet been brought to the required nominal temperature.
  • the invention therefore proposes continuing to operate the (air) heating device used for the desorption so that air is heated in the sorption drier and fed to the rinsing container. Because of the introduction of hot air into the rinsing container the rinsing liquor and/or the items to be washed continue to be heated until the nominal temperature of the rinsing liquor is reached. Since very high temperatures are reached during the desorption process in the sorption drier, more precisely in the sorption column, the rinsing liquor is heated very quickly.
  • the desorbed moisture is fed to the rinsing container.
  • the reversibly dehydratable material for desorption is heated to very high temperatures.
  • the stored liquid escapes as hot water vapour.
  • the fan is operating the water vapour is introduced into a rinsing container of the dishwasher and the air in the rinsing container is therefore also heated.
  • the introduction of the hot water vapour and the heated air into the rinsing container (rinsing container) is sufficient to heat the rinsing liquor and/or the dishes to such a temperature that the difference until the nominal temperature is reached can be attained by continuing to operate the sorption drier.
  • the additional heating device is suitably arranged in the rinsing liquor circuit and heats the rinsing liquor directly.
  • the additional heating device is designed as a water heating device, but compared to a classic heating device, such as that described in EP 0 358 279 B1, for example, it can be dimensioned much smaller.
  • the additional heating device may alternatively also be designed as an air heating device in the circuit of the sorption drier.
  • the air is passed through a fan that can be operated at a variable speed, the speed of the fan being established according to a desired duration of the partial programme step.
  • a dishwasher can be operated during the partial programme step with rinsing liquor to be heated at a constant, low and hence noise-optimised speed.
  • Such a time-reduced rinsing programme is in this case accompanied by increased operating noise.
  • the speed of the fan to be selected in a plurality of stages by a control element of the dishwasher.
  • a function can be provided in the control element of the dishwasher which enables the user to select a “Fast Rinse Programme” actively, which means that the user then actively opts for increased noise development.
  • a dishwasher according to the invention has the same advantages as those disclosed in connection with the above method.
  • a dishwasher designed according to the invention particularly a domestic dishwasher, with a rinsing container and devices for rinsing items to be washed by means of rinsing liquor, and with a sorption drier having a sorption column connected in an air-conducting manner to the rinsing container and containing dehydratable material, where on the one hand the sorption column is used to dry the dishes and on the other hand the thermal energy used for desorption of the sorption column is used for heating the rinsing liquor in the rinsing container and/or the items to be washed, the rinsing liquor can be heated to the nominal temperature required in the partial programme step concerned by means of the sorption drier.
  • the dishwasher may be designed as described in DE 103 53 774 and/or DE 103 53 775 of the applicant, whose contents are incorporated in this application where appropriate.
  • the machine described here is distinguished by its control system and the operation of the sorption drier and/or by the design of the components of the sorption drier, since the latter continues to be operated by pure dehydration of the sorption column until the nominal temperature of the rinsing liquid is reached.
  • the main control for achieving the desired operation and/or the power of the heating device and fan, as well as the volume of the sorption column are modified, e.g. in terms of their geometric design, and are matched to each other so that a further increase in the temperature of the rinsing liquor is possible merely by operating the heating device and the fan.
  • air is conducted from the rinsing container and/or from the ambient air during a partial programme step with rinsing liquor to be heated, preferably during the “Clean” and/or “Prewash” and/or “Clear Rinse” partial programme step through the sorption column and into the rinsing container.
  • the rinsing container has an outlet with a pipe to the sorption column, wherein the pipe is preferably provided with a shutoff valve and, in the direction of flow, then preferably an inlet valve for the ambient air, and the rinsing container has an inlet with a pipe from the sorption column, a fan being arranged in the pipe to the sorption column which introduces at least some of the air in the rinsing container or from the ambient air of the sorption column, at least temporarily.
  • a preferably closed air system the possibility of exchange of contaminated air from the atmosphere is completely excluded, thereby preventing recontamination of the items to be washed.
  • the fan can easily be activated so that the use of the sorption column can be precisely controlled.
  • An electric heating device is suitably arranged for desorption of the reversibly dehydratable material and for heating the rinsing liquor and/or the items to be washed.
  • This device is preferably arranged in the reversibly dehydratable material or in the pipe to the sorption column.
  • the fan of the sorption drier is designed so that it can be speed-controlled by a main control unit of the dishwasher in order to be able to control the rate of heating of the temperature of the rinsing liquor and/or the items to be washed.
  • the speed of the fan may in this case be selected preferably steplessly or in a plurality of stages by a control element of the dishwasher.
  • the method according to the invention for operating a dishwasher with at least one partial programme step with rinsing liquor to be heated to a nominal temperature and/or with at least one “Drying” partial programme step is implemented in the exemplary example described in a dishwasher which is constructed schematically, as described in DE 103 53 774 and/or DE 103 53 775 of the applicant.
  • a dishwasher has a rinsing process whose programme sequence generally consists of at least one “Prewash” partial programme step V, a “Clean” partial programme step R, at least one “Intermediate Wash” partial program step Z, a “Clear Rinse” partial programme step K and a “Drying” partial programme step T.
  • the drying is preferably carried out in the exemplary embodiment as described in DE 103 53 774 and/or DE 103 53 775, the contents of which are incorporated in this application, if appropriate.
  • the FIGURE shows a typical temperature curve of the rinsing liquor during these partial programme steps.
  • the FIGURE also shows both the operation in a conventional dishwasher and operation according to the method according to the invention.
  • the “Prewash” partial programme step V and the “Intermediate Wash” partial programme step Z are of subordinate importance for the methods according to the invention, with the result that they are not considered in detail in the following description.
  • the rinsing liquor is normally heated to a nominal temperature T nenn in order to achieve the desired cleaning effect.
  • the desorption i.e. the heating of the reversibly dehydratable material, also takes place during the “Clean” partial programme step R.
  • the contents of DE 103 53 774 and/or DE 103 53 775 are incorporated in this application, if appropriate.
  • an (air) heating device arranged in the sorption drier which contains the reversibly dehydratable material, e.g. zeolith, is heated to a high temperature.
  • air is conducted from a rinsing container, e.g. with an outlet, through the sorption column and then back into the rinsing container via an inlet, the air being heated by the heating device during its passage.
  • the air is sucked out of the rinsing container by means of a fan and forced through the sorption column.
  • the sorption drier is normally operated only until the reversibly dehydratable material is fully desorbed, i.e. dehumidified (Section A in the FIGURE). In the exemplary embodiment shown in the FIGURE, this condition is reached at a time t a when the rinsing liquor and/or the items to be washed have reached a temperature T Des . This temperature is normally below the nominal temperature T nenn to be achieved. To bridge this temperature difference the heating device and the fan of the sorption drier now continue to be operated according to the invention, and hot air is conveyed to the rinsing container, until the circulated rinsing liquor and/or the items to be washed reach the desired nominal temperature (Section B). This condition is reached with suitable dimensioning of the sorption drier, in particular the power of the heating device, the speed of the fan and the arrangement and geometry of the sorption column at a time t b .
  • the method according to the invention enables a dishwasher to be provided which may therefore dispense completely with a water heating device.
  • the rinsing liquor is heated advantageously in all partial programme steps by the air heating of the sorption drier that is of a very simple structure and can therefore be manufactured at low cost.
  • an additional heating device may be provided according to another variant of the invention, which device heats the rinsing liquor during Section A and/or during section B to increase the temperature from T Des to T nenn , so that nominal temperature T nenn is already reached at time t c (Section C).
  • the additional heating device may optionally be designed as a water heating device, e.g. a geyser, or as an air heating device inserted in the air circuit.
  • the additional heating device can be dimensioned so that only a low heating power need be made available that is capable of bridging the missing temperature difference between T Des and T nenn .
  • T nenn in the exemplary embodiment t b or t c
  • the heating phase of the rinsing liquor is completed, resulting in a reduction in the processing temperature by the end of the “Clean” partial programme step R.
  • the extent to which the processing temperature falls and the duration of this fall depend on the type of cleaning programme carried out and on the insulating characteristics of the dishwasher.
  • the items to be washed are dried by so-called intrinsic heat drying in the “Clear rinse” and “Drying” partial programme steps (Section 1).
  • the rinsing liquor is heated in the “Clear rinse” partial programme step, as a result of which the items to be washed, clearly hot rinsed by the intrinsic heat of the items to be washed thus developed, are automatically dried during the drying process.
  • the rinsing liquor is therefore heated in the “Clear rinse” partial programme step to temperature T K and applied to the items to be washed by spraying devices. Because of the relatively high temperature of the rinsing liquor in the “Clear rinse” partial programme step, normally ranging from 65° C. to 75° C., a sufficiently quantity of heat is transferred to the items to be washed so that the water adhering to the items to be washed evaporates due to the heat stored in the items to be washed.
  • a considerable energy saving is achieved by the use of sorption driers because heating of the rinsing liquor in the “Clear rinse” partial programme step K is not necessary in principle in these devices (Section 2), but can nevertheless be carried out to a small extent (Section 3).
  • the drying is achieved in that air is conducted in the “Drying” partial programme step from the rinsing container and/or from ambient air through the sorption column into the rinsing container, the sorption column containing the reversibly dehydratable material extracting moisture from the air during its passage. Because of the use of reversibly dehydratable material with a hygroscopic property, e.g.
  • heating of the items to be processed is not normally necessary in the partial programme step preceding the “Drying” partial programme step (Section 2), but heating to low temperatures, e.g. up to 30° C., can still be carried out during “Clear rinsing” (Section 3). Due to heating of the air by means of the sorption column, in which the condensation heat of the water vapour is released, its moisture absorptivity is increased during each passage through the sorption column, which results in an improvement in the drying result and to a shortening of the drying time.
  • Additional heating of the air with a supplementary heating device in the “Drying” partial programme step besides heating with the sorption column, and hence also heating of the dishes in dishwashers, for example, is not normally required because the thermal energy released in the sorption column is sufficient to heat the air to high temperatures, e.g. 70° C.
  • the sorption column itself is heated by the condensation heat to temperatures of up to 160° C., for example.
  • An acceleration of the drying process which in conventional dishwashers takes place by means of a time programme control system and lasts until time t 1 , can be achieved by providing the fan whose speed can be controlled steplessly or in a plurality of stages in the sorption drier.
  • the adsorption process is accelerated by the increase in speed, resulting in a shortening of the drying time.
  • drying can be terminated as early as time t 2 (Section 2).
  • a further reduction in drying time is achieved by the heating of the clear rinse temperature described above (Section 3), enabling drying to be completed at time t 3 .
  • the drying efficiency and degree of drying of the items to be dried are identical in all three variants.
  • This invention provides a method with which it is possible to operate a dishwasher of the type mentioned economically and to minimise the associated energy expenditure in a time-optimised manner.
