Definitions
- the invention relates to a domestic dishwasher with a washing container, in the treatment chamber at least one loading unit is accommodated for receiving Spülgut too, and at least one washing device for acting on the treatment chamber with rinsing liquid.
- a domestic dishwasher usually performs one or more liquid-conducting partial rinses, such as pre-rinse cycle, cleaning cycle, intermediate rinse cycle, rinse cycle, and then rinsing a final drying cycle at the end of a selected dishwashing program.
- the respective rinsing liquid-carrying section Whygangs rinsing liquid is distributed by means of at least one washing device such as a rotating spray arm, a fixed spray nozzle such as overhead shower, a movable spray nozzle such as roof gyros, and / or other sosstiksverteilvorraum in the treatment room of the washing container of the household dishwasher, in particular sprayed, and thereby mounted on items to be washed items such as dishes and / or cutlery, which are stored in and / or on at least one loading unit, such as a retractable dish rack or a, preferably removable or extendable, cutlery drawer.
- a washing device such as a rotating spray arm, a fixed spray nozzle such as overhead shower, a
- the respective washing device is preferably supplied by a set in operation circulating pump via at least one supply line with rinsing liquid, which collects at the bottom of the washing preferably in a recess, in particular in a sump. If heating of the rinsing liquid is required in the respective liquid-conducting partial rinsing cycle, the rinsing liquid is heated by means of a heating device. This can be part of the circulation pump. At the end of each liquid-carrying Section Whygangs which in the treatment chamber of the washing container respectively existing rinsing liquid is pumped out of this partially or completely by means of a drain pump.
- drying systems with associated drying methods are available. These are in particular the so-called self-heat drying, condensation drying (in particular eg by means of Heat exchanger on a side wall of the washing to cool them), drying by a door opener at the end of the drying cycle, convection drying under
- this leftover residual liquid can usually be removed by the user only by manual tilting away from the respective items of washware and / or manual drying by means of a tea towel, which is uncomfortable and time-consuming.
- such puddles in top recesses of Spülgut turnover after the drying cycle lead to unsightly, persistently adherent deposits or water edges, since in the standing rinse liquid dirt particles, cleaning agents, rinse aid, lime and / or other additives are included, after the partial or complete Drying of the puddles in the respective well remain as solid residues.
- a dishwasher with an air pressure injection system comprises a compressed air distributor with a plurality of fixed nozzle channels, which are evenly distributed in the interior of the washing container of this dishwasher on the ceiling wall.
- the nozzle channels together provide many individual nozzles that are directed downwards.
- short bursts of compressed air ie focused compressed-air jets, can escape from these nozzles down to associated location points in the upper dish rack, which is located below the compressed air distributor, are ejected.
- the compressed air distributor is fed from outside via a supply line compressed air from a compressed air tank, which is housed in the bottom or base of the dishwasher below the washing compartment.
- a compressor which fills the compressed air tank with compressed air.
- DE 10 2015 013 364 A1 provides a predrying device within a housing of a dishwasher in addition to a cleaning device and a drying device.
- the predrying device comprises at least one nozzle which can be aligned with the respective dish part, through which the crockery part can be acted upon by an air jet in order to remove rinsing liquid left behind from its upper-side depression there after the cleaning cycle.
- the invention has for its object to provide a domestic dishwasher with an alternative way, by means of the respective Spülgutteil, which is stored in / or on a loading unit in the treatment room of the washing, a topside existing amount of liquid, in particular one in a top recess such. Mulde, sink, Kehlung, or other cavity of each Spülgutteils standing fluid accumulation, largely remove.
- the household dishwasher according to the invention thus provides an alternative in comparison to the individual air nozzles of US Pat. No. 6,053,185 and DE 10 2015 013364 A1 Device ready, with the from the stored in and / or on a loading unit Spülgut kind upper side existing amounts of liquid, especially in the upper side wells of the Spülgutmaschine standing liquid accumulations, can be largely eliminated quickly and easily.
- one or more fans are housed in the treatment room of the washing, for a desired Abblas staresphase directly present in the treatment room of the washing, the inner air in the treatment room of the washing itself, and actively accelerate so that their each a flow pulse is given, which is sufficient, a largely existing on the respective Spülgutteil amount of liquid, in particular a standing in an upper-side recess of the respective Spülgutteils liquid accumulation, largely blow.
- This blow-off of liquid from the respective washware part only by means of accelerating the air which is already present in the treatment room works in an advantageous manner in particular simply, quickly and efficiently.
- the one or more rotationally driven fan wheels can be structurally simple to accommodate in the treatment room of the washing compartment, which favors the mass production of household dishwashers in millions of units.
- a compressed air supply from the outside as in US 6,053,185 is not provided and not required.
- pressure losses, as they can go along with the accommodated in the base of the dishwasher of US 6,053,185 compressor and compressed air tank and the long Drucktufthochrock admir avoided.
- one and the same basic type of household dishwasher can be easily equipped from the factory with and without fan or fan wheels in the treatment room. This simplifies the mass production of different variants of household dishwashers. Also, a household dishwasher with one or more fan wheels can be retrofitted in a simple manner, since their treatment room is easily accessible by opening their door. In addition, no additional space is needed in the base of the domestic dishwasher for the compressor and the compressed air tank as in US 6,053,185.
- the one or more housed in the washing room or treatment room fan wheels against soiling such as food residues, fats, etc. and / or rinsing liquid, in particular rinse, less sensitive than the air nozzles of US 6,053,185 and DE 10 2015 013364 A1. While the air nozzles and their associated compressed air lines or compressed air ducts in the dishwashing operation of a dishwasher by dirt particles, food residues, detergents, lime, etc. ...
- Shades of the airflow generated by the respective fan during its rotation operation on their way to the top of the respective Spülgutteils by adjacent Spülgutmaschine are in this movement of the air flow with a drive direction from top to bottom, ie of a region of the treatment room in which the respective fan is provided and which is selected above the unloading loading unit, down to the stored in and / or on the loading unit Spülgutmaschine, hardly or not at all present.
- directional and / or spatial information such as top, bottom, side, front, back, vertical, horizontal, etc. ... as well as terms with directionality and / or spatial reference such as front side, back, Sidewall, floor, ceiling, etc. ... to be understood from the perspective of a user standing in front of the household dishwasher and operating and using it as intended. This looks from its position on the front, especially front door, the household dishwasher when the front door is in its Schnd ein. When the front door is completely opened, for example, for unloading or loading the washing room or treatment room and is preferably in an approximately horizontal position, the user looks in the depth direction into the treatment room or washing room.
- a dishwashing program to be carried out is understood to mean a washing phase during a liquid-conducting partial wash cycle, while the dishwashing liquid is distributed, in particular sprayed, in the treatment space by means of the at least one washing device. That during the course of a dishwashing program to be carried out, one or more liquid-conducting partial rinses (such as, for example, a preliminary rinse, a cleaning cycle, an intermediate rinse, and a final rinse cycle) and subsequently a final rinse cycle drying operation are already described in more detail in the introduction to the description.
- liquid-conducting partial rinses such as, for example, a preliminary rinse, a cleaning cycle, an intermediate rinse, and a final rinse cycle
- One or more liquid-conducting partial rinses such as the intermediate rinse can be dispensed with or else carried out several times.
- the washing device can preferably be formed by a spray arm which can be rotated during the respective washing phase with a plurality of spray nozzles, from which rinsing liquid is sprayed into the treatment space.
- the rinse cycle of the respective dishwashing program is finally followed by a drying cycle, during which the wet rinsed with rinsing liquid, clean rinsed items to be washed dried.
- the loading unit to be unloaded is an upper dish rack, which is located in the treatment room above a lower dish rack at a distance from it and can be moved out of the processing room when the front door of the dishwasher is open.
- the upper crockery basket preferably has a lattice structure of longitudinal and transverse wires. Through the open areas of this Lattice structure of the upper crockery washing liquid can usually be sprayed from below the spray nozzles of a arranged below the upper crockery basket, preferably held on this, rotatable spray arm.
- the items to be washed for spraying their contaminated by food and / or drinks cavities with flushing liquid are usually turned upside down, that is set upside down.
- Such Spuckmaschine are for example cups whose bottoms (viewed in their position of use) curved inward and / or are covered by a downwardly projecting edge.
- bowls, bowls, drinking glasses, and / or other crockery, and / or cooking utensils such as wooden spoon, pots, egg cups, etc. ... can after their turned off parking in the loading unit on their top then coming to lying floors or shelves respectively Have a recess in which rinsing liquid has accumulated after the implementation of the respective liquid-carrying section istgangs and stops there.
- the respective fan wheel in the treatment chamber of the washing compartment (which is flushed and wet during flushing) is driven in rotation, it can generate an air flow or a wind from the air present in the treatment room, which is preferably already from the air outlet area of the fan wheel up to the point of impact in and / or on the loading unit, in particular at the point of impact in and / or on the loading unit, viewed in cross-section, ie viewed in a sectional plane perpendicular to its direction of advance or direction of movement, a much larger area than an air jet in US 6,053,185 or DE 10 2015 013 364 A1, which focuses from a compressed air nozzle, that is locally expelled limited limited, and therefore only occasionally hits a fixed location in the upper dish rack.
- the air flow generated by the respective fan is in particular from the air outlet region of the fan to the impact in and / or on the loading unit in comparison to the focused air jet US 6,053,185 or DE 10 2015 013 364 A1 unglickter, ie free, and in cross section (in a Sectional plane perpendicular to its flow direction) considered much more extensive or more spacious. It is designed in particular in the form of a rotating airflow vortex, which detects a much larger impact surface in and / or on the loading unit than the narrowly focused air jet of US Pat. No. 6,053,185 or DE 10 2015 013 364 A1, each of which is exactly to a single location in the upper Crockery basket is aligned.
- the air flow generated according to the invention thus does not require precise alignment with the wash items in and / or on the loading unit. It can detect a large number of wash items at the same time.
- the loading unit can advantageously be modified with respect to its height position and thus its vertical distance to the respective fan wheel arranged above it in the adjustment ranges normally provided for it, largely without influencing the blow-off effect of the air flow.
- Successfully carried out tests have shown that it is expedient if the respective fan is expediently provided at a height distance between 2 cm and 50 cm above the extended or extensive Abblas Kunststoffs the Spülgutmaschine- receiving surface of the loading unit to be passed, in particular the upper crockery basket.
- each with a focused air jet in contrast, in the dishwasher of US 6,053,185 a plurality of compressed air lines with very many nozzle openings evenly distributed over the roof level of the washing required. This can be too expensive under some circumstances.
- gaps between the focused air nozzle jets remain due to the spatial distances or distances of the fixed, stationary air nozzles from each other, so that in the intermediate region between each two adjacent, at fixed locations in the upper dish basket impinging air jets may not be sufficiently strong air jet for pushing away a standing amount of liquid an upper-side depression point of a washware item positioned there is present.
- the respective fan wheel in the treatment chamber of the washing compartment does not produce a focused, ie closely guided or limited, largely rectilinear air jet, which only points at points during its rotation operation a predetermined location of the Spülgutablage matters the below him arranged loading unit impinges, that is, "focused" on a singular point or on a locally very narrowly defined zone of Spülgutablage-1 the loading unit, but a freer, in cross section (viewed perpendicular to the air flow direction) broadened air flow , in particular a rotating airflow vortex, which actively sweeps the SpülgutablageTECH the loading unit much more spacious, ie large area or extended (as a focused air jet) with the air present in the treatment chamber of the washing container
- the blow-off area of the loading unit detected is thus extended (ie, larger) than the focused impact zone of an air jet generated by a compressed-air nozzle.
- the air flow generated by the respective fan wheel covers a wide-area blow-off area of the loading unit, which corresponds to at least 10%, in particular between 20% and 100%, preferably between 20% and 25%, particularly preferably about 25% of the total take-up area or Spülgutablageamide the loading unit , It is thus possible that with the same air flow generated by the respective fan wheel during its rotation operation, a multiplicity of washware parts can be hit or detected simultaneously, which are deposited on the washware storage surface of the loading unit and in the extended or extensive blow-off region lie.
- the blowing off of any liquid present on the respective items of washing items, in particular a quantity of liquid standing on the upper side thereof becomes more independent of the respective storage location of the items to be washed in the loading unit.
- the generated by a rotating fan, free air flow which is designed in particular as Heilstromwirbel, acts on a much larger impact surface on the upper side receiving or Absteil constitutional the loading unit with air as the focused air jet from a single compressed air nozzle.
- it preferably has approximately the same view over its cross-sectional area and in particular at each impact location of its impact area covered or occupied by it on the loading unit Flow impulse on.
- the air flow generated according to the invention by means of a rotating fan wheel thus acts on the surface hit by it in and / or on the loading unit and thus the items to be washed there, preferably more homogeneously or uniformly than by the individual air jet jets of the nozzle field of US Pat. No. 6,053,185 or DE 10 2015 013364 A1 is possible.
- the respective fan is designed such that during its rotational operation during one or more Abblas jossphasen each considered in a sectional plane perpendicular to the air flow direction large-scale air flow, in particular a rotating Heilstromwirbel generated, considered perpendicular to its main flow direction, a cross-sectional area preferably between 450 cm 2 and 2000 cm 2 for a domestic dishwasher with 45 cm standard width and 60 cm standard depth, and preferably between 500 cm 2 and 2500 cm 2 at one Household dishwasher with 60 cm standard width and 60 cm standard depth has.
- the respective fan is designed as an axial fan, in particular as a propeller or impeller.

- This pumping process is again denoted by AP in FIG.
- the spraying operation of the at least one washing device in the treatment room BR has been stopped at the end of the final rinse cycle KG, in particular the spraying operation of the upper spray arm OS and the lower spray arm US ceases by the circulation operation UP of the circulation pump CP has ended and that in the upper one Crockery basket If the items to be washed are no longer supplied with rinsing liquid spray jars, the ABG blow-off operating phase may begin. In the embodiment, therefore, the Abblas jossphase ABG already starts during a End section tKE - tBS of the rinse cycle KG.
- the electric drive motors AM1 to AM4 of the fan wheels LR1 to LR4 are each operated in rotation in succession in time.
- the fan wheels LR1 to LR4 are each driven to rotate individually in a sequential sequence during specifically allocated runtime subsections or individual run times LZ1 to LZ4.
- the fan wheel LR1 driven by its electric drive motor AM1 generates an associated air flow LS1 in the treatment room BR down to the first quadrant Q1 of the upper basket OK during the runtime subsection or time span LZ1.
- the electrical drive motor AM2 of the second fan wheel LR2 is switched on later in time and operated this alone for a period of time LZ2.
- the air flow LS2 generated by it alone acts on the second quadrant Q2 of the upper crockery basket OK.
- the electric drive motor AM3 of the third fan wheel LR3 is operated alone for a single run time LZ3.
- the air flow LS3 generated by the third fan LR3 alone then acts on the third quadrant Q3 of the upper crockery basket OK.
- the drive motor AM4 of the fourth fan wheel LR4 is finally switched on for a single run time LZ4 and operated alone. All other drive motors AM1, AM2, AM3 are switched off.
- the airflow LS4 generated by the fourth fan alone acts on the fourth quadrant Q4 of the upper rack OK.
- the blow-off operating phase ABG extends over an initial period of the drying cycle TG.
- a single run time or a selectively assigned runtime partial section is preferably selected between 5 sec (seconds) and 30 sec, in particular between 8 sec and 20 sec, preferably of about 15 sec ,
- This results in a total running time of the Abblas jossphase ABG preferably between 20 sec and 120 sec, in particular between 32 sec and 80 seconds, preferably of about 60 sec. may be compared to this information, the total duration of time due to any pauses or dead times between the individual running times of the fan wheels preferably by 10% to 20% longer.
- the Abblas jossphase ABG can advantageously integrate without significant delays in the usual timing of the rinse SG or insert.
- the drying cycle TG can, for example, with the help of so-called Self-heating of the items to be washed done. This is based on the fact that the items to be washed have been heated by the rinsing liquid which has been heated during the rinsing liquid application operation of the one or more preceding partial rinses, in particular during the cleaning cycle RG and / or rinse cycle KG. As a result, the rinse liquid droplets adhering to the items to be washed evaporate and are taken up by the air in the treatment space.
- the Spül raw materials are compared to the Spülgut former and existing in the treatment room air / steam mixture cooler, it depends on this to condense the moisture from the air / water vapor mixture.
- other drying systems with associated drying methods are available for drying. These are in particular, for example, the condensation drying - also by means of heat exchangers - on a side wall of the washing to cool them, drying by a door opener at the end of the drying cycle, a convection drying with the aid of a fan, a Sorptionstrocknung, etc.
- the blow-off operating phase ABG is expediently carried out before and / or during an initial section of the drying cycle TG. This ensures that quantities of liquid or accumulations of liquid on the upper sides of the items to be washed, for example in upper-side depressions, are promptly blown off and run off to the bottom of the washing container. It may therefore be expedient to put the drain pump DP into operation during the blow-off operating phase ABG and to pump the water thus blown out of the dishwasher. This favors the drying of Spülgutmaschine in the upper basket OK. In this way it is possible to properly dry even the top-side wells of Spülgutieri, especially there to avoid drying edges that would otherwise result from residual solids in the fluid collections.
- the items of items to be washed can largely dry out completely, so that manual drying of the items to be washed or even pouring of the liquid accumulations remaining in the upper-side recesses of the items to be washed into the kitchen sink by the user is no longer necessary.
- the user is spared the fact that, when unloading the washware parts, after the end of the drying cycle TG, he remains inadvertently dumping liquid quantities of the items to be washed left in depressions in the items to be washed, which would lead to wetting or even soiling of the stored in the lower basket UK Spülgutmaschine. In this way, the comfort for the user is considerably increased.
- the Abblas jossphase ABG can be inserted in a simple manner between the end of Klar Whygangs KG and the beginning of the drying cycle TG, since their total time is quite short, in particular less than 120 seconds, preferably less than 90 seconds.
- a Abblas In addition or independently of the Abblas waterssphase immediately before and / or at the beginning of the drying cycle, it may be appropriate, a Abblas waterssphase after the remplisstechnikssbeaufschlagungs-, in particular spraying, at least one of the liquid-carrying Rail Touch Vietnamese, such as the cleaning cycle, the another liquid-conducting Section Touchgang how For example, an intermediate rinse or rinse cycle, to follow.
- the best possible removal of remaining liquid quantities from the upper sides of the items to be washed, in particular from their upper-side depressions is also advantageous because because thus an undefined rinsing liquid level in the washing, in particular for the subsequent rinsing liquid-carrying sectionumblegang is respectively avoided.
