Definitions
- the invention relates to a dishwasher with a washing container.
- 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 "rinsing" part program step and the hot, rinsed items are automatically dried by the self-heat of the item to be washed during the drying process the partial program step "rinse" heated to a certain temperature and applied to the items to be washed via spraying. Due to the relatively high temperature of the rinsing liquid in the partial program step "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 method for operating a dishwasher is known from DE 30 21 746 A1, in which a heat exchanger connected to the washing container during a partial program step "drying" is fed with cold fresh water Since the temperature difference between the moist air and the filled fresh water is relatively low and the amount of fresh water is constantly heated, there is the disadvantage that the condensation of the moist air takes a long time and steadily decreases, so that the outlet of moist air from the dishwasher increases and the duration of the partial program step "drying" is long, with a moderate drying result.
- 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 must be regenerated for each heating phase 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 dishwashing machine according to the invention with a rinsing container has an air-conduction system connected to the rinsing container, in which at least one Peltier element is arranged, the Peltier element being used on the one hand for cooling and thereby drying and on the other hand for heating air conducted through from the rinsing container.
- Peltier element only requires a considerably lower heating of the material to be treated compared to the prior art, e.g. In dishwashers, in the sub-program step "rinsing", this means a considerable saving in energy.
- the cooling of the air reduces its moisture absorption capacity and the moisture content of the air condenses.When the air warms up, its moisture absorption capacity is restored each time it passes through the piping system In the closed air system, the exchange of polluted air from the environment is completely eliminated, which prevents back soiling of the treated material provided, with which it is possible to efficiently clean and dry the items located in the washing container and to keep the associated energy consumption as low as possible.
- air is passed from the washing container in the at least one partial program step "drying" in the conduit system and back into the washing container, whereby the above-mentioned advantages in the inventive dishwasher are used as intended.
- the washing container has an outlet with a line to a part of the Peltier element, a line from one part of the Peltier element to the other part of the Peltier element and an inlet with a line from the other part of the Peltier element, wherein in the line to one Part of the Peltier element, a fan is arranged, which supplies at least a portion of the air in the washing container to the line system at least temporarily.
- a fan is arranged, which supplies at least a portion of the air in the washing container to the line system at least temporarily.
- the blower is easy to control, so that the use of the Peltier element can be precisely and easily controlled.
- the fan increases the effect of the Peltier element, since the air to be conveyed is conveyed faster.
- the air is cooled by means of the Peltier element.
- 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 Peltier element.
- the further function of the already existing Peltier element - the transported heat absorbed when cooling the moist air and condensing the moisture from the moist air - is used for further energy savings.
- a heater is arranged in the line between the other part of the Peltier element and the inlet. If the heating of the air by the Peltier element 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 line between the outlet and the one part of the Peltier element or alternatively in the line between the one part of the Peltier element and the other part of the Peltier element. 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.
- FIGURE shows a dishwashing machine 1 according to the invention in a schematic representation with a washing container 2 in which dish baskets, not shown, are arranged for the arrangement of dishes, not shown.
- the dishwasher 1 has an air line connected to the washing container 2 conduit system 4, in which at least one Peltier element 10 is arranged, wherein the Peltier element 10, as will be explained in more detail below, on the one hand for cooling and thereby for drying and on the other hand for heating fürméer Air from the washing compartment 2 is used.
- a Peltier element 10 is a heat pump with a heat extracted area - this is cooled - and transported to another area - this is heated, the heat at high speed and large amount of a part 11 - the so-called “Cold side” - the Peltier element 10 to the other part 12 - the so-called “warm side” - the Peltier element 10 is passed.
- electrical current is applied to the Peltier element.
- the introduced moist air is conducted to the "cold side" 11 of the Peltier element 10, it cools the moist air and thus reduces the moisture absorption capacity of the moist air, as a result of which the moisture contained in the moist air condenses Moist air thus heat (sensible heat) and also absorbs the resulting heat of condensation (latent heat) and transports the heat to the other part 12 - to the "warm side" of the Peltier element 10th
- the rinsing container 2 has an outlet 3 which leads to the line system 4 with a line 5 for a part 11 of the Peltier element 10, with a line 6 from one part 11 of the Peltier element 10 to the other part 12 of the Peltier element 10 and with a line 7 of FIG the other part 12 of the Peltier element 10 leads to an inlet 8 of the washing container 2, wherein in the conduit 5 to a part 11 of the Peltier element 10, a fan 9 is arranged, which supplies at least a portion of the air in the washing tank 2 the conduit system 4 at least temporarily.

- a condenser 16 is arranged in the line to a part - to the "cold side” - of the Peltier element possible. If the dehumidification of the air by the Peltier element 10 is insufficient, the air is additionally conducted past the condenser 16 to ensure the drying function, which carries out the lack of dehumidification. This condenser 16 is in thermal contact with the environment.
- a dishwasher 1 is known to have a rinsing process whose program sequence consists, for example, of at least one partial program step "prewash”, one partial program step “cleaning”, at least one partial program step “intermediate rinse”, one partial program step “rinse-out” and one partial program step “drying”.
- air is led out of the washing container 2 during the "drying" partial program step through the line system 4 and back into the washing container 2.
- the blower 9 is switched on The air path is indicated by the arrows A, B, C and D.
- the Peltier element 10 conducted air is removed from the "cold side” 11 of the Peltier element 10 a lot of heat energy so that it cools very strong and cold air as a has much lower moisture absorption, is doing a large proportion of the moisture condenses.
- heat-conducting ribs 13 are arranged.
- the Peltier element 10 conducts the heat removed from the moist air (sensible heat) and the heat produced during the condensation (latent heat) to its other part 12 - the "warm side” of the Peltier element 10. For this purpose, electrical current is applied to the Peltier element 10.
- the now very dry air passes via the line 6 from one part 11 of the Peltier element 10 to the other part 12 of the Peltier element 10 and is heated there. For good heat conduction from the Peltier element 10 to the air heat conducting fins 14 are arranged.
- the now heated and very dry air now passes via the line 7 from the other part 12 of the Peltier element 10 to the inlet 8 of the washing container 2 and thus back into the washing 2.
- heated air is now much dry and has a high absorption capacity for moisture. It rises in the washing container 2 upwards and absorbs the residual moisture on the items to be washed. It will now, as already described above, fed back to the Peltier element 10.
- a dishwasher 1 is provided, with which it is possible to efficiently clean and dry the items located in the washing container 2 and to keep the associated energy consumption as low as possible.
