Definitions

  • the invention relates to a dishwasher with a washing container, an ozone generator and devices for rinsing items to be washed by means of rinsing liquor.
  • 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”.
  • the heating of the rinsing liquid is usually carried out by means of electric heaters.
  • Sorptionstrockenvorraumen For drying the items to be washed in a dishwasher different drying systems are known, including the use of so-called Sorptionstrockenvorraumen.
  • a dishwasher with such a drying system is in the DE 20 16 831 described.
  • this is attached to a wall of the washing container connected to the interior thereof by a closable opening container for receiving a desiccant, which absorbs moisture and is able to give off again when heated.
  • Dishwashers generally have the problem that a longer standstill time, while the soiled dishes are arranged in the dishwasher, when opening the door is a unpleasant smell for the user the result.
  • the dishwasher has a memory for ozone and / or hydroxyl radicals, which conducts air conductively to the rinsing container, preferably on the one hand for the absorption of ozone and / or hydroxyl radicals during its production or on the other hand serves for the discharge of ozone and / or hydroxyl radicals during a partial program step "drying" and / or a stoppage phase of the dishwasher.
  • Such a memory for receiving ozone and / or hydroxyl radicals has the advantage that at certain specified times ozone and / or hydroxyl radicals can be passed into the washing compartment of the dishwasher to prevent unpleasant odors and thus for increased hygiene of the Spül actuallyerinneren also during a prolonged standstill phase.
  • an ozone generator for this purpose, which generates ozone during a partial program step of a washing program in which the dishes are treated with washing liquor and introduces this into the washing liquor.
  • the ozone generator can be arranged, for example, in the rinsing vessel interior, in order then to introduce ozone (O 3 ), for example during a partial program step "cleaning" and / or "rinsing".
  • O 3 ozone
  • the ozone dissolved in the rinsing liquor initially advantageously serves to increase the cleaning effect of the relevant part program step.
  • a part of the ozone which can be supplied to the store and stored in it is gassed, in order then to be discharged during a partial program step "drying" and / or a standstill phase of the dishwasher. Since the delivery takes place at a time when the dishwasher is not exposed to any rinsing liquor, the ozone is used for deodorizing the rinsing container and / or the items to be washed in it.
  • the memory is also able to store hydroxyl radicals which have the same effect. Hydroxyl radicals are used in the dishwasher in the Wash liquor formed and can also be supplied to the memory according to the invention.
  • a blower which can be controlled by a controller in order to store the ozone and / or the hydroxyl radicals in the store and to store out the ozone and / or the hydroxyl radicals from the store.
  • the fan is controllable by the controller during the standstill phase, wherein the control is carried out periodically or in response to the opening or closing of a door contact of a door of the dishwasher.
  • the storage is formed by a sorption column containing reversibly dehydratable material.
  • Zeolite is particularly suitable as reversibly dehydratable material.
  • Dishwashers with such a sorption column are known in principle from the prior art and are used for drying the dishes during the partial program step "drying". In order to effect a deodorization of the washing container and / or the dishes, therefore, only an ozone generator must be provided in such a dishwasher to the already existing Sorptionstrockenvoriques to first introduce the ozone in the wash liquor, then the gassed during circulation proportion of ozone in the To manage and store memory.
  • the particular advantage of the invention is that for deodorizing the washing container and / or the dishes during a standstill phase, ie at times when the dishwasher is out of service, only a fan must be operated, which briefly and / or periodically Operation is taken. In contrast to the operation of an ozone generator during such a standstill phase, this results in the advantage that only a low energy consumption during this stoppage phase suggests.
  • a blower is operated during a period outside a partial program step of a rinse program in which the ware is treated with rinse liquor, stored in a memory
  • a blower is operated during a period outside a partial program step of a rinse program in which the ware is treated with rinse liquor, stored in a memory
  • the ozone in the reservoir and / or the hydroxyl radicals are consequently discharged therefrom by putting the blower into operation.
  • a reversibly dehydratable material e.g. Zeolite, used, which can absorb moisture under condensation heat and release the stored moisture in it again.
  • the reversibly dehydratable material is capable of buffering ozone and / or hydroxyl radicals and releasing them again by generating an air flow, so that it can be conducted into the rinsing container and / or the items to be washed for deodorization.
  • ozone is introduced into the rinsing liquor in a subprogram step in which the wash ware is treated with rinsing liquor, and the blower is operated to charge gassed ozone and / or formed hydroxyl radicals into the air conductively connected to the rinse container during this partial program step To direct memory.
  • the introduction of the ozone into the rinsing liquor is carried out according to a further advantageous variant using an ozone generator.
  • the fan is operated during a standstill phase of the dishwasher to initiate the ozone and / or the hydroxyl radicals to avoid a fermented, musty odor in the washing.
  • a standstill phase is understood to mean the idle state of the dishwasher.
  • the blower is also advantageous to operate the blower at periodic intervals to achieve the desired deodorization.
  • the periodic, preferably short-term, operating the fan also ensures low energy consumption of the dishwasher.
  • the fan is operated in response to the opening or closing of a door of the dishwasher. For example, it can be assumed that after opening and closing the dishwasher new, soiled dishes were introduced into the washing. With a predetermined time offset, the fan can then be put into operation to neutralize outgoing odors from the newly added, soiled items.
  • the single FIGURE shows a schematic representation of a dishwasher 1 according to the invention with a washing container 2, in which dish baskets 3, 4 are arranged for the arrangement of not darg Congressm items to be washed.
  • the dishwashing machine according to the invention is equipped with a sorption drying device 14 which is known in principle from the prior art.
  • the dishwasher 1 has a reversibly hydrogenatable material 11, which is air-conductively connected to the washing container 2, e.g. Zeolite, containing Soprtionskolonne 10, wherein the sorbent 10, as will be explained in more detail below, on the one hand used for drying and on the other hand for heating air passed through.
  • the rinsing container 2 has an outlet 5 arranged in the described embodiment in its upper region with a line 6 to the sorption column 10 and an inlet 8 arranged in its lower region in the described embodiment with a line 7 from the sorption column 10.
  • a fan 9 is arranged, which supplies the sorption column 10 air from the washing container 2.
  • an exchange of polluted air from the environment is completely excluded, whereby a scananschomutzung the treated material is prevented.
  • an electric heating element 12 in the sorption column 10 is arranged in the exemplary embodiment shown.
  • the operation of such Sorptionsstrockenvoriques 14 is known from the prior art, for example DE 20 16 831 or the DE 103 53 774.0 and or DE 103 53 775.9 known in principle, so that at this point, with reference to the local disclosures waived a closer execution.
  • an ozone generator 13 is furthermore provided in the washing container 2, which, in principle, can be arranged at any point in the washing container.
  • the ozone generator 13 is operated during a partial program step with circulating rinsing liquor, so that this produces ozone produced by him in the rinsing liquor to increase their cleaning effect.
  • the fan 9 is operated during the circulation of the ozone-added rinsing liquor, so that this gasified ozone and hydroxyl radicals formed in the rinsing liquor are conducted via the outlet 5 and the line 6 in the direction of the sorption column 10.
  • the sorption column 10 containing the reversibly dehydratable material 11 serves as a buffer for the ozone and / or the hydroxyl radicals.
  • the blower 9 is e.g. operated in response to the opening and closing of the (not shown) door of the dishwasher 1 with a time delay. It is sufficient to operate the fan 9 only for a short period of time to only a portion of the ozone stored in the sorption column 10 and / or the hydroxyl radicals via line 7 and the inlet 8 into the washing container 2 to conduct.
  • the fan 9 regardless of the times of opening and closing the door of the dishwasher, could be operated at periodic intervals.
  • the sorption column serving as a storage, independently of its function for accelerating the drying process during a partial program step "drying".
  • the provision of the heating element 12 in or near the sorption column 10 would be dispensable.
  • a dishwasher with which it is possible to hygienically store the Spül variouserinnere and / or the dishes to be washed even during a prolonged standstill phase, since the disinfected in the Spül electerinnere ozone disinfects the air. Ozone can not be identified by a user due to its low dose.
