Definitions

  • the invention relates to a dishwasher with a washing container and devices for washing dishes.
  • a dishwasher has a washing method whose program sequence generally consists of at least one sub-program step “pre-wash”, a sub-program step “cleaning”, at least one sub-program step “intermediate washing”, a sub-program step “rinsing” and a sub-program step “drying”.
  • the rinsing liquid is heated before or during a partial program step.
  • the rinsing liquid is usually heated by means of electrical heaters.
  • Different drying systems are known for drying items to be washed in a dishwasher.
  • the items to be washed can be dried by self-heat drying if the washing liquid is heated in the “final rinse” sub-program step and thus the hot-rinsed items dries automatically due to the inherent heat generated by the items during the “drying” sub-program step.
  • the rinsing liquid in the partial program step "final rinsing" e.g. in a heat exchanger, heated to a certain temperature and applied to the items to be washed via spray devices available in the dishwasher.
  • the relatively high temperature of the washing liquid in the "final rinse" subprogram step of usually 65 ° C to 75 ° C ensures that a sufficiently large amount 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.
  • a separate heat source for example a hot air blower, is used in the washing compartment to heat the moist air mixture during the drying process so that the air in the washing compartment can absorb a larger amount of moisture.
  • Dishwashers are known in which the moist air is vented to the outside. This is disadvantageous because the surrounding kitchen furniture is damaged.
  • a dishwasher of the type mentioned is known in which the air from the washing compartment is passed through a closable opening in the wall of the washing compartment onto reversibly dehydratable material and from there to the outside via an opening.
  • the desorption of the reversibly dehydratable material takes place during the standstill phase of the device, whereby the water vapor that is produced in the process is directed to the outside again via the opening.
  • this is disadvantageous because the surrounding kitchen furniture is damaged.
  • a disadvantage of the heating systems described above according to the prior art described above is that the heating of the rinsing liquid is associated with a high energy requirement and the required thermal energy must be generated anew for each heating phase by means of the electrical heating elements.
  • the known heating systems also have the disadvantage that the heating of the rinsing liquid in the sub-program step "rinsing" and the processes in the sub-program step “drying" themselves are associated with a high energy requirement and the required thermal energy is lost after the drying process.
  • a rinsing liquor is heated by a water heater arranged outside its rinsing container and pressed into a distribution and spray system by a pump.
  • a largely closed drying system is used for a drying process, in which air circulates from the washing compartment via a drying device which can be regenerated by heating and from this circulates back into the washing compartment.
  • the drying device consists of a drying container which is in thermal contact with the heater and which is filled with a drying agent that adsorbs moisture, such as a zeolite.
  • the air flow of the drying system is with provided a closure that interrupts the air circulation during the washing of the dishwasher.
  • the US 6,434,857 B1 relates only to a washer-dryer whose tumbler is separated from the circuit of a drying system by a valve during a washing cycle.
  • the object of the present invention is therefore to provide a dishwasher with which it is possible, from an economic point of view, to efficiently clean and dry the items to be washed in the washing compartment and to keep the associated energy consumption as low as possible.
  • This object is achieved by the dishwasher according to the invention having the features according to claim 1.
  • Advantageous further developments of the present invention are characterized in the subclaims.
  • the dishwasher according to the invention with a washing container and devices for washing dishes using washing liquor has a sorption column that is connected to the washing container in an air-conducting manner and contains reversibly dehydratable material, the sorption column on the one hand for drying the dishes and on the other hand for desorption of the sorption column to heat the heat energy used in the Rinsing container located washing liquor and the dishes is at least partially usable.
  • reversibly dehydratable material with hygroscopic properties, e.g. B. zeolite
  • heating of the items to be treated is preferably not necessary in the part program step "rinsing".
  • a heating of the items to be treated in the partial program step which precedes the partial program step “drying”, in particular the partial program step “final rinsing”, is possible, but not useful. Nevertheless, a slight warming during "rinsing", z. B. to 30 ° C, be appropriate. This means a substantial energy saving.
  • the generally always occurring warming of the air due to the released heat of condensation in the sorption column in the part program step "drying" increases its moisture absorption capacity each time it is passed through the sorption column, which improves the drying result and shortens the drying time Drying time leads.
  • An additional heating of the air with a heater in the partial program step "drying" and thus also of the dishes is normally not necessary because the sorption column due to the heat of condensation of the steam to high temperatures, z. B. 150 ° C, heated, and thereby the air sufficiently high temperatures, z. B. 60 ° -70 ° C reached.
  • the reversibly dehydratable material is heated to very high temperatures for desorption, for which purpose thermal energy is necessary.
  • the stored liquid emerges as hot water vapor.
  • the water vapor is preferably passed into the treatment room of the device with an air stream and the air in the treatment room is thus heated and thereby the washing liquor and / or the dishes are also heated.
  • the air that is passed through cools down, causing the water vapor to partially condense at the top. This is preferably done as a closed air circuit.
  • the introduction of the hot water vapor and the heated air into the treatment room during a partial program step with the treatment liquid to be heated or, under certain circumstances, with the treatment liquid that has already been heated is largely sufficient to heat the treatment liquid sufficiently. This means that further heating can largely be dispensed with and the thermal energy used for desorption can be used almost entirely to heat the treatment liquid, rinsing solution and / or dishes, apart from the low energy required to overcome the binding forces between water and reversibly dehydratable material . In addition to saving energy, efficient cleaning of the items to be treated is also guaranteed.
  • the present invention provides a dishwasher with which it is possible, from an economic point of view, to efficiently clean and dry the items to be washed and to keep the associated energy consumption as low as possible.
  • the rinsing container has an outlet with a line to the sorption column, the line preferably having a shut-off valve and then, in the flow direction, preferably an inlet valve to the ambient air, and the rinsing container also has an inlet with a line from the sorption column, wherein in a fan is arranged in the line to the sorption column which at least temporarily introduces at least part of the air in the washing container or from the ambient air of the sorption column.
  • a fan is arranged in the line to the sorption column which at least temporarily introduces at least part of the air in the washing container or from the ambient air of the sorption column.
  • the fan can be easily controlled so that the use of the sorption column can be precisely controlled.
  • the fan increases the effect of the sorption column, since the air to be passed through is conveyed more quickly.
  • the sorption column has a container for the reversibly dehydratable material, which allows the exchange of moisture and / or heat between the reversibly dehydratable material and the air surrounding it.
  • a heating element preferably an electrical heating element, is arranged for desorption of the reversibly dehydratable material.
  • the heating element is arranged in the line to the sorption column for desorption of the reversibly dehydratable material (11).
  • the air that can be introduced into the washing container via the inlet can be cooled so that the dishes are not damaged by high temperatures.
  • a droplet separator is arranged at the outlet or the line at the outlet is led up a partial area so that no spray water reaches the sorption column via the line.
  • the thermal energy used for desorption is prior to use for heating the washing liquor and / or the dishes in a heat store, e.g. B. latent storage, storable.
  • a heat store e.g. B. latent storage, storable.

  • air is passed from the washing container 2, on the one hand, through the sorption column 10 and back into the washing container 2 during the “drying” part of the program.
  • the fan 9 is switched on.
  • the airway is indicated by the arrows A, B and C.
  • the air introduced into the sorption column 10 by the fan 9 via the line 6 is withdrawn from the reversibly dehydratable material 11 of all moisture.
  • the air is heated by the heat of condensation of moisture or water vapor released in the sorption column, which advantageously increases the air's moisture absorption capacity.
  • the now warmed, z. B. up to 40 ° -70 ° C, and very dry air now passes through line 8 back into the rinsing container.
  • the heated air introduced into the washing compartment 2 is completely dry and, due to the higher temperatures, has a high absorption capacity for moisture. It rises in the washing compartment 2 and absorbs the residual moisture on the items to be washed. As already described above, it is now fed back to the sorption column 10.
  • air from the washing container 2 is passed through during a partial program step with washing liquid to be heated or possibly already heated, preferably during the partial program step "cleaning" and / or "pre-rinse", in the described embodiment during the partial program step "cleaning” the sorption column 10 and passed back into the washing tank 2.
