Definitions

  • the invention relates to a dishwasher with a washing container and a pipe system connected thereto with air conduction.
  • a dishwasher has, as is known, a rinsing process whose program sequence consists of at least one partial program step "pre-rinsing", one sub-program step “cleaning”, at least one sub-program step “intermediate rinsing", one sub-program step "rinsing” and one sub-program step “drying".
  • a rinsing process whose program sequence consists of at least one partial program step "pre-rinsing", one sub-program step “cleaning”, at least one sub-program step “intermediate rinsing", one sub-program step "rinsing” and one sub-program step “drying”.
  • the heating of the rinsing liquid is usually carried out by means of electric heaters.
  • the items to be washed can be dried by self-heat drying if the rinsing liquid is heated in a rinse-out subprogram step and the hot, rinsed items are automatically dried by the self-heat of the item to be washed during the drying process.
  • the rinsing liquid is heated to a certain temperature in the partial program step "rinsing" and applied to the items to be washed by means of spraying.
  • rinsing usually from 65 ° C to 75 ° C is achieved that a sufficiently large amount of heat is transferred to the items to be washed, so that the water adhering to the items by the heat stored in the items to be washed evaporated.
  • a separate heating source e.g. a hot air blower, used in the rinsing tank to heat the humid air mixture during the drying process, so that the air in the washing container can absorb a larger amount of moisture.
  • a dishwashing machine in which a heat pipe protrudes into the washing and forms a cooling surface there.
  • the heat released by the hot humid air is transported to the outside by means of the heat pipe. So that the heat pipe does not dissipate heat during partial program steps in which heating in the washing compartment is desired, the heat pipe is filled with an inert gas in these partial program steps, which prevents the function of the heat pipe.
  • a heat exchanger is connected to the washing container via channels in such a way that air is conducted from the washing container by convection and / or by a blower over the heat exchanger.
  • the heat exchanger consists of a latent heat storage, which cools the air from the washing, whereby water condenses from this.
  • This cooled air whose water content has been reduced by condensation, is returned to the washing compartment. There it warms up by contact with dishes, baskets, and the container walls of the washing container. As the temperature increases, the relative humidity of the recirculated air decreases. As a result, they can absorb moisture again in the washing container and the cycle can be run through the heat exchanger again.
  • the refrigerator of US 3,985,182 A liquid-filled cuvette extends through an insulating wall into a higher temperature compartment and at the same time into a lower temperature compartment to transfer heat from the higher temperature compartment to the lower temperature compartment.
  • the two cooling compartments are separated from each other by the insulation wall so that no air exchange takes place.
  • 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 heat energy for each heating phase must be recreated by means of the electrical heating elements.
  • the known heating systems have the disadvantage that the heating of the rinsing liquid in the partial program step “rinse" and the operations in the sub-program step “drying" are themselves associated with a high energy demand and the required heat energy is lost after the drying process.
  • the dishwasher according to the invention with a rinsing container has an air-conductively connected to the rinsing tank line system, projects into the at least one heat pipe with both ends, wherein the heat pipe on the one hand for cooling and damaschine.
  • the fan increases the effect of the heat pipe, since the air to be conveyed is promoted faster.
  • the air is cooled by means of the heat pipe.
  • the cooling is used with removal of the absorbed heat energy.
  • the air By cooling the air, its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate.
  • the air is heated by means of the heat pipe.
  • the further function of the already existing heat pipe-the transported heat is absorbed when cooling the humid air and condensing the moisture from the moist air-used to further save energy.
  • a heater is arranged in the line between the inlet and the other end of the heat pipe. If the heating of the air through the heat pipe is not sufficient, the air is additionally heated with a heater to ensure the drying function. Despite the additional energy consumption for the heating energy savings compared to the above-described prior art is achieved.
  • a condenser is arranged in the conduit between the outlet and the one end of the heat pipe or alternatively in the conduit between the one end of the heat pipe and the other end of the heat pipe. If the dehumidification of the air through the heat pipe is not sufficient, the air is additionally passed to a condenser to ensure the drying function, which performs the missing dehumidification.
  • FIGS. 1 ', 1 ", 1'” show embodiments of the dishwasher 1, 1 ', 1 ", 1'” according to the invention with a washing container 2, 2 ', 2 ", 2"' are arranged in the dish baskets, not shown for the classification of items not shown.
