Definitions

  • the invention relates to a method for operating a device with at least one sub-program step "drying", as it is e.g. is used in tumble dryers, dishwashers, dishwashers, shoe dryers etc.
  • the items to be washed can be dried by self-heating if the washing liquid is heated in a sub-program step "rinse-off" and thus the hot, rinsed items are self-drying due to the inherent heat of the items to be washed during the drying process the sub-program step "final rinse” heated to a certain temperature and applied to the items to be washed using spray devices.
  • a separate heating source e.g. a hot air blower, used to heat the moist air mixture during the drying process so that the air in the washing container can absorb a larger amount of moisture.
  • Dishwashers are known in which the moist air is discharged to the outside. This is disadvantageous because the surrounding kitchen furniture is damaged.
  • a disadvantage of the heating systems 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 has to be generated anew 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 sub-program step “rinse-off" and the processes in the sub-program step “drying” are themselves associated with a high energy requirement and the required thermal energy is lost after the drying process.
  • the object of the present invention is therefore to provide a method with which it is possible to operate devices of the type mentioned at the outset as economically as possible, to dry the material to be dried efficiently and to keep the associated energy expenditure as low as possible.
  • a Peltier element is a heat pump with which heat is extracted from one area - this is cooled down - and transported to another area - which is heated.
  • heating of the material to be treated which is significantly less than in the prior art, is only necessary, e.g. in dishwashers in the sub-program step "rinse aid". This means a significant energy saving.
  • By cooling the air its moisture absorption capacity is reduced and the moisture content of the air precipitates as condensate.
  • By heating the air its moisture absorption capacity is increased each time it is passed through the line system, With the closed air system, an exchange of polluted air from the environment is completely ruled out, thus preventing the treated material from being contaminated back.
  • the present invention provides a method with which it is possible to operate devices of the type mentioned at the outset as economically as possible, to dry the material to be dried efficiently and to keep the associated energy expenditure as low as possible.
  • the air is conveyed by means of a blower, which makes it easier to control the use of the Peltier element.
  • the air is cooled by means of the Peltier element.
  • the actual function of a Peltier element, cooling with removal of the absorbed thermal energy, is thus used in accordance with the method according to the invention.
  • By cooling the air its moisture absorption capacity is reduced 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 is thus taken up - the transported heat when cooling the moist air and during Condensation of moisture from the moist air - used for further energy saving.
  • the air is heated by means of a heater. 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 heating, an energy saving is achieved compared to the previously described prior art.
  • the air is directed past a condenser. If the removal of moisture from the air is not sufficient due to the cooling by the Peltier element, the air is additionally directed past a condenser to ensure the drying function, which performs the lack of moisture removal.
  • a dishwasher has a rinsing method whose program sequence consists of at least one sub-program step "pre-rinse”, a sub-program step “cleaning”, at least one sub-program step “intermediate rinsing", a sub-program step "rinsing” and a sub-program step "drying".
  • air is passed out of a treatment room out of it via a line system in which at least one Peltier element is arranged and back into it, the air being cooled during the passage and thereby moisture withdrawn and then heated again.
  • the treatment room of the dishwasher - the washing container - is equipped with an outlet in the upper region of the washing container. From this outlet leads an air line to a blower and from the blower to the Peltier element.
  • a Peltier element is a heat pump with which heat is extracted from one area - this is cooled - and transported to another area - which is heated, the heat being produced at high speed and in large quantities by one part - the so-called “cold side” "- of the Peltier element to the other part - the so-called” warm side "- of the Peltier element. If the introduced moist air is directed to the "cold side” of the Peltier element, 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. The "cold side” of the Peltier element thus extracts the heat (sensitive heat) from the moist air and also absorbs the heat of condensation (latent heat) and transports the heat to the other part - for "heating" the Peltier element.
  • a further air line leads from the "cold side" of the Peltier element to the "warm side” of the Peltier element and from there to an inlet located in the lower region of the rinsing container.
  • the heated air introduced into the rinsing tank is now much drier and therefore has a high moisture absorption capacity. It rises in the washing compartment and absorbs the residual moisture in the items to be treated - the items to be washed. As already described above, it is now fed back to the line system.
  • the air is additionally directed past a condenser to ensure the drying function, which performs the lack of moisture removal.
  • the condenser can be arranged in the flow direction of the air before or after the “cold side” of the Peltier element, in the exemplary embodiment described it is arranged after the “cold side” of the Peltier element.
  • the air is additionally heated with a heater to ensure the drying function.
  • the heater is arranged shortly before the treated air is admitted to the rinsing container. Despite the additional energy consumption for heating, an energy saving is achieved compared to the previously described prior art.
  • the present invention provides a method with which it is possible to operate devices of the type mentioned at the outset as economically as possible, to dry the material to be dried efficiently and to keep the associated energy expenditure as low as possible.

Abstract

La présente invention concerne un procédé pour faire fonctionner un appareil ayant au moins une partie de programme "séchage", le procédé permettant à des appareils ayant au moins une partie de programme "séchage", de fonctionner avec une économie maximale, de sécher les objets à sécher de façon efficace en consommant un minimum d'énergie. A cet effet, au cours de la/des partie(s) de programme "séchage", de l'air sort d'un espace de traitement par un système de conduite dans lequel se trouve au moins un élément de Peltier, puis est réintroduit dans celui-ci, l'air étant refroidi à son passage dans la conduite, ce qui permet de lui en extraire son humidité, puis à nouveau réchauffé.
