Definitions

  • the invention relates to a dishwasher with a rinsing container and devices for rinsing dishes by means of rinsing liquor and with a Sorptionstrockenvorraum which is connected to the rinsing air-conducting via an outlet of the rinsing and an inlet of the rinse and having a sorption column with reversibly dehydratable material.
  • the invention further relates to a method for operating such a dishwasher.
  • Conventional dishwashing machines are known to have a rinsing process whose program sequence generally consists of at least one partial program step "pre-rinsing", one sub-program step “cleaning”, at least one subprogram step “intermediate rinsing", one subprogram step “rinsing” and one subprogram step “drying”.
  • pre-rinsing partial program step
  • cleaning at least one subprogram step "intermediate rinsing”
  • a further disadvantage is that damage to the surrounding kitchen furniture can not be ruled out by discharging the water vapor produced during the regeneration of the reversibly dehydratable material to the outside.
  • the regeneration is associated with an additional energy requirement, which is incurred in addition to the energy required during the sub-program steps.
  • the Applicant discloses a dishwasher with a rinsing container and devices for rinsing crockery by means of rinsing, which has a sorptionskolonne containing air-conducting, reversibly dehydratable material containing the rinsing, wherein the sorption on the one hand for drying the dishes and on the other hand for the desorption of the sorption used thermal energy Heating the rinsing liquor and / or the dishes located in the washing container is at least partially used.
  • a dishwashing machine with a closed drying system in which the air circulates from the washing container via a regenerable by heating drying device and from this back into the washing.
  • the drying device is assigned to the heater arranged outside the washing compartment for the washing liquor, preferably a continuous flow heater.
  • the outlet of the washing container is located in the ceiling of the washing container, while the inlet is integrated in the washing tub of the washing container.

  • the air duct in the bottom region has a controllable valve for discharging water condensed in the air duct.
  • the condensed and discharged water then no longer has to be absorbed by the reversibly dehydratable material, so that the sorption column of the sorption drying device can be made smaller in comparison with a conventionally designed sorption drying device without condensation surface.
  • this can gain valuable space again.
  • the air duct on a pressure-regulating means which ensures in the case of an overpressure occurring in the washing container for a pressure equalization.
  • the pressure-regulating means may be designed as an actively operable valve.
  • the pressure regulating means may, according to another embodiment, passively open or close due to the pressure inside the washing compartment, and e.g. be designed as a flap.
  • a negative pressure is formed in the air duct, so that the pressure-regulating means acts in a sealing manner.
  • the pressure regulating means may open and thus reduce the pressure generated inside the purge tank.
  • the sorption drying device preferably arranged in the bottom area of the dishwasher below a rinsing tray, it is expedient to integrate the inlet of the rinsing container into the rinsing tray itself, as this results in a waiver of a further air channel. As a result, a simpler and more cost-effective production is possible.
  • a passive closure means against penetrating water it is provided to provide the outlet and / or the inlet with a passive closure means against penetrating water.
  • this can be a cover over the outlet or inlet, which is preferably designed such that the flow direction of the air flow is determined at the same time is to achieve the best possible turbulence of the air in the washing, so that a good moisture absorption is realized.
  • the closure means may be designed to be operable, for example, by applying a voltage.
  • the closure means may thus be designed motor or hydraulic. It is particularly preferred if voltage is applied to the closure means with the application of a voltage to a fan, so that open the closure means, thereby creating an air circulation to Sorptionstrockenvoriques.
  • the inlet and outlet only have to be opened during the regeneration phase of the sorption column and during the partial program step. "During the remaining part program steps, the closure means ensure a secure seal in order to prevent the penetration of spray water into the sorption drying device having electrical functional elements.
  • the closure means can also be actuated by a temperature-sensitive memory metal.
  • the control of the closure means is not carried out in an electrical manner, but is caused due to the prevailing temperatures during different part program steps.
