Definitions

  • the invention relates to an arrangement for drying dishes in household dishwashers according to the preamble of patent claim 1.
  • an arrangement for drying dishes in dishwashers having a washing container, a container arranged separately from the washing container, a blower for conveying moist air from the washing container through the arranged separately from the washing container Container to the rinsing tank is equipped, with fresh water being introduced into the tank arranged separately from the rinsing tank.
  • moist air is drawn in from the washing container by means of the blower and passed through the container which is designed as a condenser and is arranged separately from the washing container.
  • Fresh water is introduced via a cooling water line, which is conducted in turns through the condenser, and emerges from the cooling water line in the flow direction at the end of the condenser in its outlet.
  • the moist air is cooled along the cooling water line, so that the moisture contained in the moist air condenses and is returned as condensate via the outlet of the condenser with the outflowing fresh water into the rinsing container.
  • the cooled air also flows through the condenser outlet into the rinsing container and can now absorb moisture by heating up the dishes and be conducted to the condenser.
  • the fresh water is pumped through a drain hose into the sewer.
  • a disadvantage of the arrangement described above is the consumption of a large amount of fresh water solely for condensing the moisture contained in the moist air.
  • the object of the invention is to provide an arrangement for drying dishes in dishwashers, in which consumption of fresh water is avoided solely for the drying program section.
  • this object is achieved by a method in that the moist air is conducted in a container which is arranged separately from the washing container over the surface of fresh water stored for the next washing operations.
  • the container which is arranged separately from the rinsing container, is filled with fresh water only at least at the beginning of the drying program section.
  • means are provided for measuring the temperature of the fresh water stored in the container arranged separately from the rinsing container, via which control elements for filling a further quantity of fresh water into the container arranged separately from the rinsing container can be controlled when a definable temperature increase is determined.
  • the inevitable heating of the fresh water by the humid air conducted over it is specifically eliminated with this measure while avoiding any unnecessary consumption of fresh water, so that the result of the cooling of the humid air and the condensation of the moisture contained therein remains the same over the entire drying process.
  • the blower is directed in such a way that the moist air is sucked in from a pump pot arranged in the lower region of the washing container and introduced into the upper region of the washing container again.
  • the cooled air introduced into the upper area of the washing compartment sinks downwards and inevitably heats up on the dishes to be dried, thereby absorbing moisture.
  • suction is drawn in from the lower area of the washing compartment, thus ensuring an optimal, closed air circuit.
  • the moist air in the container which is arranged separately from the rinsing container is advantageously directed from above onto the water surface.
  • a meandering guide for the moist air is provided in the container, which is arranged separately from the rinsing container, so that the largest possible contact of the moist air with the surface of the fresh water and thus optimal cooling of the introduced moist air is achieved.
  • the container which is arranged separately from the rinsing container is a water inlet container with at least one water inlet and one water outlet and at least one air inlet and one air outlet, in the wall of which a temperature sensor is provided.
  • a water inlet container is used to stock and measure the amount of fresh water required for a washing program section, so that the arrangement according to the invention ensures that the fresh water introduced during the drying program section is kept in stock for the next washing processes and that fresh water consumption for the drying program section alone is completely avoided.
  • the separate water and air circuits guarantee a trouble-free process of cooling the moist air in the drying program section, as well as a trouble-free process of filling the stored water into the washing container in one of the next washing program sections.
  • the temperature sensor ensures the control of control elements for the introduction of a further quantity of fresh water.
  • in the water inlet container there is at least one vertical one that starts from a wall of the water inlet container Partition provided.
  • the meandering guidance of the moist air over the surface of the stored fresh water is thus effected with simple measures.
  • the at least one partition is expediently produced in one piece with the wall of the water inlet container.
  • the blower is advantageously arranged in a moist air line running from the pump pot to the air inlet into the water inlet container.
  • the moist air line is made at least partially in one piece with the water inlet container along the course thereof.
  • the housing of the fan is expediently made at least partially in one piece with the moist air line and the water inlet container.
  • a pump pot 2 arranged at the lower end of the rinsing container 1 moist air is introduced into the water inlet container 10 through an air inlet 13 via a moist air line 21 by means of a blower 20 which is arranged in this wet air line 21.
  • the air passes through the air outlet 14 via an air outlet line 15 in a closed circuit back into the washing container 1.
  • the direction of flow of the air is indicated by arrows with the designation 22.
  • a temperature sensor 25 is provided in the wall of the water inlet container 10.
  • the water outlet 12 In the direction of flow 22 at the lower end of the water inlet container 10 is the water outlet 12, which is closed by means of a commercially available valve, for example a solenoid valve which can be controlled by a program control unit of the household dishwasher.
  • a commercially available valve for example a solenoid valve which can be controlled by a program control unit of the household dishwasher.
  • the moist air line 21 is at least partially made in one piece with the water inlet container 10 along its course.
  • the housing of the blower 20 with the moist air line 21 and the water inlet container 10 is at least partially made in one piece.
  • the dishes are stored in dish racks (not shown) in the washing container 1.
  • the dishes are heated in a conventional dishwasher using very warm washing liquid, which in the drying program section following the pumping out of the washing liquid leads to the fact that washing liquid adhering to the dishes evaporates and is heated by the heated ones in the washing container Air is absorbed as moisture.
  • the resulting moist air is, according to the invention, introduced from the rinsing tank 1 by means of the blower 20 into the water inlet tank 10, which is filled with fresh water at least at the beginning of the drying program section. Through the air inlet 13 directed downward in the direction of flow 22, the moist air in the water inlet container 10 is directed from above onto the water surface.
  • a lowest level of the water surface is indicated at 17. Since the air inlet 13 is arranged at an outer corner of the cuboidal water inlet container 10, for example, the moist air has to flow around the partition walls 16 and is given a meandering guidance over the surface of the fresh water.
  • the inevitable heating of the fresh water is measured by the temperature sensor 25, which is arranged below the level 17 in the wall of the water inlet container, the temperature of the fresh water continuously or cyclically and compared with a definable temperature increase value.
  • the temperature sensor controls, for example by means of an impulse, control elements for the filling of a further quantity of fresh water into the water inlet container 10, for example a program control device (not shown) of the dishwasher which, for example, does not open by opening one shown water inlet valve of the dishwasher initiates the filling of a further quantity of fresh water into the water inlet container.
  • the amount of further fresh water to be filled in can be controlled, for example, by the temperature sensor 25, for example when the desired colder mixing temperature has been reached, or by a time pulse, for example from the program control device (not shown), or by a device for limiting the amount.
  • the condensate that precipitates - just like the part of the fresh water that has been filled in - is stored for the next rinsing process. Consumption of fresh water only for the drying sub-program is therefore effectively excluded with simple means.
