Description

Dishwasher with a suction unit

The invention relates to a household dishwasher with a washing container whose feed opening can be closed by a door. In some dishwashers such as e.g. German patent DE 100 58 188 A1, DE 10 2007 019 298 A1 can be used to suck hot air and / or hot steam through a drying fan and release it to the outside in the respective rinse for drying items previously cleaned with liquid from the rinse container become. The exiting hot, moisture-laden air and / or the exiting hot steam, the environment exposed to significant moisture, so that in particular the dishwasher surrounding furniture can be damaged and also for a user unpleasant exposure to rising steam and / or humidigsbeladener hotter Air can take place. Therefore, in order to prevent damage to the furniture, additional steam protection sheets or foils are often mounted on the furniture. In particular, a flat steam protection element is usually attached to the underside of the kitchen worktop, below which the dishwasher is e.g. set in a niche of a kitchenette.

The invention is based on the problem of achieving an improvement here.

This object is achieved by the features of the dishwasher of claim 1 and by the features of the method of claim 22 individually considered. The dishwasher according to the invention according to claim 1 has a washing container, the loading opening is closable with a door. According to the invention, at least one suction device or suction unit is provided for sucking off steam escaping from the feed opening and / or air which is loaded, in particular with moisture laden or unpleasant odors. The

Suction device sucks such out of the feed opening

Medium at least partially away from the region of the feed opening so that this outside the feed opening far less or no unwanted Impairments, for example, on the dishwasher adjacent kitchen furniture such as a kitchen worktop, below which the dishwasher is, laterally adjacent furniture parts, and / or at a standing in front of the dishwasher user, can lead. Advantageously, the suction device is designed such that it captures the respectively flowing out of the feed opening medium to such an extent and transported away from it such that unwanted adverse effects in the external environment of the dishwasher are largely avoided by the medium. It reduces or prevents in particular that the respective medium flowing out of the feed opening continues to rise upwards to a kitchen worktop and / or to the head area of a user standing in front of the dishwasher in an impairment leading way. Thus, it can be largely avoided, in particular, that condensation and precipitation of moisture on the dishwasher are adjacent to it

Kitchen furniture, especially on the underside of the dishwasher above covering kitchen worktop can come. Also, a user standing in front of the dishwasher remains better protected when the door is opened from rising, hot steam and / or from rising moisture laden and / or odorous air.

A critical situation in which the suction device is advantageously activated is

For example, when a user tears open the door during a partial wash cycle of a dishwashing cycle, while the heated wash liquid in the interior or treatment space, i. Wet space of the washing container is sprayed by means of one or more spraying and there hot steam and / or

moisture-laden, hot air, in particular steam or vapor, are present. This and / or these would unhindered escape without activated suction from the door opening gap upwards. A further critical situation in which the suction device is advantageously activated is in particular when the door of the dishwasher is opened for drying support during the final cycle of a dishwashing program, especially in the second half of the predetermined drying period, preferably towards the end thereof. to purposely vent air and / or residual vapor laden with residual moisture from the rinse tank. For this purpose, it may be advantageous to open the door preferably automated by a door opening mechanism to a predetermined gap. In the case, that, for example, dirty dishes in the washing compartment has been stored with the door closed and it comes in the treatment room of the washing to unpleasant odors for the human nose, the deduction of the invention

odor-laden air through the suction device or suction unit also be advantageous when the door is opened. Expressed in general terms, the suction device is then advantageously turned on and for as long as possible, i. activated, as it leads to an unwanted escape from an impairing medium, in particular of steam, and / or moisture-containing and / or

odor-laden air, comes from the washing container in the external environment at the installation of the dishwasher. This flowing out of the feed opening of the rinsing tank steam and / or the outflowing from the feed opening of the rinsing air is at least partially captured or sucked away by the suction device before it can flow away from the feed opening of the washing so far that it is undesirable in the Environment, especially on the furniture and / or standing in front of the dishwasher user can come.

According to an advantageous embodiment of the invention, the suction device comprises one or more inlet windows, preferably outside of the wet space of the washing container, in particular in a front, the respective rinsing process dry edge zone of the washing container before the feed opening, preferably in front of the feed opening limiting door seal of the washing compartment provided is / are. As a result, it is largely avoided that liquid can pass through the one or more inlet windows of the suction device into its downstream components during the washing operation of the dishwasher, where it can lead to damage such as, for example, to the fan or suction fan of the suction device. Special sealing or elaborate spray water protection measures are not required in this advantageous embodiment for the suction device. The one or more entrance windows can be formed in an advantageous manner as simple breakthrough openings, for example in the form of punched holes in the edge region of the washing compartment projecting forward relative to the door seal. According to a further advantageous embodiment of the invention, it may be particularly useful if the suction device has one or more entrance windows at least in the upper region of the washing, in particular in the top wall, possibly also in the left side wall and / or in the right side wall, and one or more entrance windows are accessible from the inside of the rinsing container only for steam and / or air escaping from the wet space of the rinsing container when the door is open. As a result, complicated conversions of the washing container are largely avoided. In addition, immediately in the location area where the steam and / or air leaves the feed opening, this and / or these can be sucked through the one or more entrance window before the steam and / or the air too far away from the feed opening of the washing flow and can get to the adjacent furniture or a standing in front of the dishwasher user in an inadmissible manner.

It is particularly advantageous if the suction device is already switched on when opening the door or shortly before. As a result, hot air emerging from the initial door opening gap, in particular ascending upward, hot steam and / or gushing out, in particular ascending upward, can be sucked particularly effectively before it and / or surrounding furniture and / or the appliance standing in front of the dishwasher User reached. In particular, it is advantageous to operate the suction device then, as long as the door opening gap is small, as gushing escaping, in particular ascending, hot steam and / or gushing exiting, in particular upwardly rising hot air in a relatively concentrated form as by a chimney the door opening gap is guided and thereby effectively retained from escaping from the upper end.

It is thus useful, in particular, when the suction device is switched on at the latest when the door, in particular by means of an automatic door opening mechanism, opened and brought from its closed position to an open position in the between the door and the washing a, especially narrow, opening gap released is. Advantageously, the suction device is brought from the beginning of the door opening for a predeterminable period of time, in particular between 1 minute and 20 minutes duration, in their suction and then turned off. It may be favorable, in particular, during this suction period for an initial period of time, such as for the first minute from the beginning of the door opening, the exhaust fan of the suction device with a higher speed, ie with a higher suction power associated therewith, than in the subsequent remaining period of Extraction time to operate. As a result, the initially emerging, preferably rising upward hot steam and / or air surge can be promoted particularly effective away from the feed opening in a direction that the original outflow direction of the particular obliquely steep upward steam and / or air surge through the door opening gap differs through, in particular, this is directed opposite.

Appropriately, the suction device is turned on, as long as the door assumes a position in which the opening gap viewed in the depth direction of the washing container has a gap depth extension or gap width between 2 cm and 20 cm. This is particularly advantageous when the dishwasher according to the invention is equipped with an automatic door opening mechanism, which brings the door in a door opening parking position with such a gap width.

In addition or independently thereof, the suction device is advantageously switched on when the door is moved from its, in particular approximately vertical, closing position into a forward tilted position as parking position with an opening angle between 2 ° and 10 °, preferably by means of an automatic door opening device. In particular, it may be advantageous if the door is first opened in a first opening park intermediate position with a door opening angle between 2 ° and 3 ° relative to its closed position while the suction fan of the suction is operated at a higher speed between 30 seconds and about 1 minute. As a result, steam and / or hot air, which wants to squeeze through the narrow door opening gap in the form of a spatially concentrated air flow from the wet room or treatment room of the washing up in the outer environment of the dishwasher, before leaving the upper area the door opening gap formed between the upper edge of the door and the top wall of the washing container, are largely retained. Thereafter, the door is preferably applied in a second door opening parking intermediate position in which they are compared to their closed position, a door opening angle between 5 ° and 10 ° occupies. The suction fan of the suction device is operated with a lowered, ie lower speed between 10 minutes and 15 minutes.

According to a further advantageous development of the invention, it may be particularly advantageous for a control device to switch on the suction device when the temperature in the wet space of the washing container exceeds a predetermined threshold temperature, in particular approximately 40 ° C., above which steam is generated in the wet space of the washing container. and the presence of a door opening or the beginning of the opening of the door is detected. Furthermore, the invention solves the problem mentioned above by a dishwasher with the features of claim 8 and by a method having the features of claim 24. Further advantages and ausgestaltende features and developments of the invention are set forth in claims 2 to 7, 9 to 21, the 23rd , 25 to 27 indicated, whose features can be implemented individually or in combination with each other.

The invention relates to a domestic dishwasher with a washing container for cleaning dishes, glasses, cutlery or the like to be cleaned items, wherein the washing container is closed by a movable door to its opening, wherein the washing at least one suction or suction for in this air and a suction unit downstream of the suction are assigned. Due to the fact that in this dishwashing machine according to the invention according to claim 8 the suction or suction opening leads into a space for condensing moisture out of the intake air, less moisture is released into the environment. In the said space, a large part of the water contained in the air can condense, so that after passing through this room only a small residual moisture is contained in this air. In particular, with built-in dishwashers the surrounding furniture is spared, there can not condense water, or small amounts dry very quickly. Additional protection for the furniture is no longer required.

When the at least one suction or suction opening with the door open for emerging from the wet room of the washing and leaving steam and / or exiting air accessible is, an extraction of this steam and / or humid air can take place during the door opening, so that the steam and / or moisture from the device while the user does not hit the face or overlying furniture edge, for example, a countertop applied , Furthermore, it is possible for the at least one suction or suction opening to be accessible only when the door is open for steam and / or escaping air emerging from the wet space of the washing container. Then a contact between the washing container on the one hand and the space for condensation on the other hand, initially avoided, so that the room has a high potential for moisture absorption and in operation, especially in a drying phase, is not yet acted upon by moist warm air from the washing, but the Dampfabsaugung can only be used when the door is opening. The door can thereby be pressed by the dishwasher a bit far (ie, in a steeply upwardly inclined position), so that the suction opening (s) is optimally accessible or are and only after the extraction of the vapor and its extensive condensation the door is intended for a complete opening by the user. In any case, with the door open, the obliquely steeply upward through the door opening gap steam and / or obliquely steeply upwards through the door opening gap air is deflected by the suction by means of the suction device so that him and / or their one of the original, By natural convection conditional outflow direction deviating, in particular opposite, suction is impressed. In particular, the exiting steam and / or leaving air with the door open by the suction a substantially horizontal or downward direction, so that he can no longer rise up and moisten surrounding furniture. The steam and / or air deflection takes place via the air gap formed when the door is open and, thanks to the powerful fan, forms a closed steam and / or air flow which leads almost completely into the intake opening (s).

In particular, the suction unit can be automatically switched on by opening the door or at the same time or shortly before, whereby the efficiency is optimized and leakage of steam from the open door is minimized. In particular, lying above the slot of the dishwasher kitchen plate is thus preserved from moisture and possible mold growth. If the space is channel-like, it can save space with a small width and depth of typically only a few centimeters and yet a long length be installed in the dishwasher; This results in a large interaction surface between the humid air and the walls.

It may be useful if the room is located in the dishwasher outside of the washing. The volume of the washing container is not restricted thereby, on the other hand, any outside of the dishwasher to be mounted parts, such as deflectors or the like, are not required.

If the space for condensation is located in the door of the dishwasher, an already existing cavity between the so-called. Inner door and the outer door can be used to accommodate the channel there. In particular, a suction opening can then be extended into this space over a large part of the door width in its upper area. This wide-extending slot opening would also reliably prevent by the Ansaugzug that emerges with slightly open door of the steam upwards towards furniture.

In particular, it may be expedient if one or more inlet windows of the suction device is / are provided in the upper area of the inner wall of the door and are arranged there in an edge zone outside the collecting trough or recess of the door. When the door is closed, this edge zone is located with the one or more entrance windows outside the feed opening of the washing container, which is bounded by the inside of the door mounted door seal in the ceiling wall and the two side walls of the washing compartment. Therefore, it remains largely dry during the respective rinsing process, during which rinsing liquid is circulated and distributed in the wet space or treatment chamber of the rinsing container. It is thus largely avoided that rinsing liquid is injected into the one or more inlet openings, which are arranged on the outer edge of the inner door. Further, it is advantageous if the space from the intake opening tends to run down to at least one outlet opening. The suction opening is thus preferably higher than the outlet opening of the space of the suction unit. Then out of condensing water can run down and there, for example, back in the Run back the rinse tank. Likewise, the less humid air can then escape in the lower area, either to the washing out or to the outside.

In this case, the space may be provided at its lower end with a collecting area for liquid, which is about when the door is in operation, so that a return of residual water must take place again at the next closing of the door.

The suction opening may comprise a pattern of entrance windows, thereby allowing suction over a large area into the condensation space. Thus, for example, the front frame of the washing container, which (in the viewing direction from the front) preferably lies in front of the feed opening of the washing container and in front of the door seal partly bounding the outside, can be provided with such inlet windows at the top and at the side.

Optionally, outer walls of the condensing room can also be cooled in order to achieve a particularly high separation of water.

In operation of the dishwasher according to the invention, the aspirator is suitably switched so that when the door is opened a little way, e.g. at the end of a partial program step for drying the items to be washed, the steam exiting from the washing container and / or the moisture-laden hot air exiting through the suction unit is sucked off via an air gap formed through the door opening.

As a result, then only from the door opening gap steeply upwardly exiting steam and / or exiting moisture-laden air in this case receives a preferably horizontal component of movement and is thus supplied to the suction port. The steam and / or the air can therefore no longer escape unhindered to the outside from the air gap and thereby moisten surrounding furniture, in particular a worktop lying above the dishwasher, and condense there.

The escaping steam and / or the escaping air can in particular via an air gap of up to 20 centimeters between the washing and one opposite, in the open door located suction and thereby effectively mix with the drier outdoor air.

If the dishwasher at the end of the drying process, in particular after its completion, (or to support the drying even during the drying phase), the door opens automatically while or shortly before the suction unit, it ensures that much steam and / or humid air can escape and yet the exhaust unit with open door can work immediately with their full power and so takes place from the beginning of the vapor and / or air deflection of the ascending direction in a deviating, in particular substantially horizontal, or even opposite flow direction.

Other developments of the invention are given in the dependent claims.

The above-explained and / or reproduced in the subclaims advantageous embodiments and refinements of the invention can - in addition to z. B. in cases of clear dependencies or incompatible alternatives - individually or in any combination with each other.

The invention and its advantageous embodiments and further developments and their advantages will be explained in more detail with reference to exemplary embodiments illustrative drawings. They show, in each case in a schematic outline sketch:

Fig. 5 shows an alternative embodiment of a space for condensing laterally of the

Rinse container with entry windows at the side and above the front edge of the washing container.

Elements with the same function and mode of operation are each provided with the same reference numerals in the figures. Dishwasher 1 shown schematically in FIG. 1 is a domestic dishwasher and is shown here by way of example only as a standalone appliance. In particular, the invention is also for appliances installed in kitchen furniture of great importance. The dishwasher shown here therefore has an externally closed body 5, which is not mandatory. In the body 5 is a washing container 2 for receiving items to be processed dishes such as dishes, pots, cutlery, glasses, cooking utensils u. Ä. Provided. The items to be washed can, for example, be held in dish racks 1 1 and / or a cutlery drawer 10, and in doing so by rinsing liquor, i. Rinsing liquid, e.g. Fresh water or treated with detergent or rinse fresh water be acted upon. The rinsing container 2 may have an at least substantially rectangular floor plan with a front side V facing a user in the operating position. The front V can form part of a kitchen front of kitchen furniture standing side by side or even be without reference to other furniture in a stand-alone device.

The washing container 2 can be closed by a door 3, in particular on this front side V. This door 3 is shown in Figure 1 in partially open and then inclined to the vertical position. In its closed position, however, it stands upright and is according to the drawing to its opening about a lower horizontal axis forward and downward in the direction of arrow 4 swung open, so that it is at least almost horizontal in the fully open position. An automatic Intermediate position of the door 3 with only a small opening, such as during or after the end of a drying program step, is possible.

At its in the closed position about vertical, facing the user outer and front V, the door 3 may be provided with a decorative plate 6, so as to experience a visual and / or haptic appreciation and / or adaptation to surrounding kitchen furniture.

The dishwasher 1 is designed as a standalone or as a so-called. Semi-integrated or as a fully integrated device. In the latter cases, the outer body 5 can be partially omitted.

The movable door 3 is assigned here in the embodiment according to the drawing in its upper part a transversely Q extended control panel 8, which may preferably include a front accessible access opening 7 for manually opening and / or closing the door 3.

Furthermore, the washing container 2 is assigned at least one suction opening 12 (see FIGS. 2-4) or 13 (see FIG. 5) to an extraction device 28 for air and / or steam contained therein. The suction opening 12 is in the representation of the suction device 28 of Figure 2 in the door 3 on its inner, in the closed position the washing compartment facing side. The additional or alternative suction opening 13 of the suction device 28 of Figure 5 includes in their representation a plurality of individual entrance windows 14 and extends in the body 5 at the front V associated lateral edges 15 and at an upper edge 16 of the washing container 2. Other arrangements are possible. In this case, the respective intake opening may be continuous or interrupted. Likewise, a plurality of suction openings may be provided at a distance from each other. It may be sufficient in particular for sucking off steam and / or moist hot air, which rises with the door open through the then existing door opening gap, if several inlet windows 14 only in the front edge of the top wall 33 of the washing compartment 2 and possibly in the upper region of the front edge of the two side walls 34, 35 of the washing compartment 2 are provided. Further, the or the suction port (s) at least one suction unit 17, 18 downstream, for example, a fan or blower, as in the embodiments drawn here. The suction unit 17 (Figure 3) is located in the door 3 and can rotate about a horizontal axis. The suction unit 18 is preferably located on the body 5 above the washing container 2, that is, on the top wall 33 thereof and may, for example, rotate about a vertical axis. Alternatively, it may be externally attached to one of the side walls 34, 35 of the washing container 2.

In any case, the at least one suction opening 12, 13 leads into a space 20, 21 for condensing moisture out of the air sucked in from the washing tank 2 and / or steam 22.

In the embodiment of Figures 2 to 4, the space 20 of the suction device 28 is channel-like and is located outside of the washing compartment 2, namely in the door 3, in an already existing cavity between the so-called. Interior door and the outer door. The channel-like space 20 has (viewed in the vertical closed position of the door) in the depth and width direction only an extension of a few centimeters, in the height direction, however, of a few tens of centimeters, for example from about 30 to 50 centimeters, so that through the channel 20th moving, drying air or steam 23 travels a considerable way, on which they can deliver water to the sewer walls.

The suction opening 12 of the suction device 28 of the embodiment of Figures 2. 4, which supplies the space 20 with air, is, as described above, in the door 3 on its inner side and is thereby extending in the manner of a cross-Q current slot opening over a large part of the door width in the upper region. In the illustration according to FIG. 2, the intake opening 12 preferably extends over the full width of the door.

In the door 3 is behind the suction port 12, a transversely extending air duct 19 as a component of the suction device 28, in which takes place during the suction or suction air movement to the suction unit 17. The conveyed through the suction air is then transported down into the space 20 and can largely condense out there. The channel-like space 20 extends down to at least one Outlet opening 25. This can be aligned in the direction of the washing container 2, so here to the inside of the door 3 out.

In the lower region of the channel-like space 20 there is also a collecting area for liquid, so that when the door is closed 3 water collected there flows back into the washing container 2 again.

The suction unit 17 is operated so that it may be e.g. to aid drying even during the drying phase or e.g. is switched on at the end of a partial program step for drying the dishes, and that when the door 3, in particular automatically, a little way open and thereby emerging from the washing tank 2 steam and / or moisture-containing air through the suction unit 17 via an air gap formed through the door opening is sucked off. As a result, exiting steam and / or moisture-containing air then preferably receives a horizontal component of movement and is thus supplied to the door-side intake opening 12. This is particularly very wide, for example, about 40 centimeters at a 45 centimeters wide machine 1 or about 55 centimeters at a 60 centimeters wide machine 1. Thus, the steam is sucked over its entire outlet width of the suction unit 17 into the suction port 12. The steam and / or the moisture-containing air can / can therefore no longer escape unhindered in the air gap and thereby moisten surrounding furniture, in particular an overlying worktop, and condense there. The suction opening 12 can for this purpose have a height of several centimeters, up to about 5 centimeters.

The exiting steam and / or the moisture-containing air can be considered over an air gap of several centimeters (up to about 12 centimeters) in the depth direction of the dishwasher between the washing and an opposite, located in the door 3 suction port 12 and thereby effectively with mix the drier outside air. In particular, the suction unit 17, in particular an intake fan, is already switched on shortly before the door opening. As soon as the door 3 in particular opens automatically and switches on or shortly before the suction unit, it is ensured that a lot of steam and / or moisture-containing air can escape and still the suction or Suction unit 17 with the door open 3 can work immediately with their full power and so takes place from the beginning of the vapor and / or air deflection of the ascending direction in a substantially horizontal direction of flow.

In addition to or independent of an automatic door opening caused by a door opening mechanism, the suction unit 17 can be activated in particular when the onset or the beginning of a door opening is detected. So this is e.g. also the case when the user opens the door during a partial rinse with heated rinse liquid such as e.g. open the cleaning cycle or rinse cycle. Preferably, the suction unit is such as e.g. 17 or 18 connected to a control device 32 of the dishwasher, which activates the suction unit by means of a control signal on receipt of a door call signal representing a not shown control line or signal line. The control device 32 is additionally shown in phantom in FIGS. 1 and 5. In the figure 5, the control, in particular the switching on and off of the suction unit 18 by the control device 32 schematically indicated by an arrow WP.

In the embodiment of Figure 5, the space 21, which is part of the suction device 28, also has a channel-like design and is located outside the washing compartment 2, namely with a first, horizontal portion above the washing compartment 2 on the outside of the top wall 33 and a further, vertical Again, the vertical portion of the channel-like space 21 in the depth and width direction each only an extension of a few centimeters, but in the height direction of a few tens of centimeters, for example from about 30 to 50 Centimeters, so that here also moving through the channel 21, drying air or steam 23 travels a considerable way on which they can deliver water to the sewer walls. The space 21 is preferably formed by a flat channel. Due to the additional horizontal section on the top wall 33 of the washing container 2, the channel 21 is further extended and thus offers even more space to condense water. At least one wall of the channel 21 may optionally be formed by walls of the washing compartment 2. The other walls can be made of plastic or metal. The generally designated 13 suction port of the suction device 28, which supplies the space 21 with sucked steam and / or sucked air is, as described above, at the front V facing the end of the washing container 2 and comprises a plurality of small, spaced apart individual entrance windows 14 in upright edge regions 15 and in a transversely extending Q upper edge region 16. In the illustration of Figure 5, the suction port 13 is thus a total of U-shaped two front lateral edges 15 of the washing and the upper edge or the cross-connection 16 of the washing extends.

In particular, according to an advantageous embodiment variant of the invention, however, it may be sufficient to provide a plurality of inlet windows distributed over the width of the washing container or a single inlet opening extending across the width of the washing container only at the front upper edge of the ceiling. At best, one or more entry windows may be expediently additionally provided in the upper region of the respective side wall.

These one or more entrance windows preferably penetrate the top wall and / or the respective side wall of the washing compartment from the inside thereof, i. in the vertical direction. This is shown here only schematically in the embodiment of Figure 5. Of course, other arrangements of one or more entrance window are possible.

Advantageously, the inlet windows such as 14 in Figure 5 are preferably outside the wet room such as 26 of the washing such as 2, in particular in a front, during the respective rinsing dry edge zone such as 15, 16 of the washing before the feed opening such as 27 provided, the is limited by an attached there door seal such as 30 of the washing compartment. As a result, these entrance windows are only accessible when the door is open for steam and / or air escaping from the wet area, such as, for example, 26 of the washing compartment, such as, for example, 2. It is thus also largely avoided that during the washing operation of the dishwasher liquid through the multiple inlet window of the suction device such as 28 through its downstream components such as their fan or exhaust fan such as 18 can get there and can lead to damage. Special sealing or elaborate spray water protection measures are in this advantageous variant for the suction device not required. The one or more entrance windows 14 are here in the embodiment of Figure 5 preferably formed as a simple breakthrough openings such as in the form of punched in the front of the door seal 30 forwardly projecting edge region of the washing. As a result, complicated conversions of the washing container are largely avoided. In addition, immediately in the location area where the steam and / or air leaves the feed opening, this and / or these can be sucked through the one or more entrance window before the steam and / or the air too far away from the feed opening of the washing flow and can get to the adjacent furniture or a standing in front of the dishwasher user in an inadmissible manner.

The entrance window 14 open in the embodiment of Figure 5, outside the washing container 2 in an air intake passage, which here preferably also takes the form of a downwardly open U ^'s and in which takes place a movement of air to the suction unit, in particular to the suction blower 18 during the suction. This lies on top of the top wall 33 of the washing compartment 2 and concentrates the air moved in the air intake duct into the horizontal portion of the channel-like space 21 described above. The air which has entered there is then conveyed downwards in the vertical portion of the space 21 and can largely condense out there , The channel-like space 21 runs down to at least one outlet opening 25. This can be aligned in the direction of the washing container 2. Alternatively or additionally, it would also be possible to blow out the largely dried air 23 to the outside. The air intake duct 21 is shown schematically in Figure 5 the sake of simplicity only above the top wall 33, while it is omitted in the outer region of the side walls 34, 35 and there only the entrance window 14 are visible.

In the lower part of the channel-like space 21, there may also be a collecting area for liquid, so that the liquid can in any case run back into the washing container 2, even if the air 23 is blown outwards.

In this variant, in addition, in a critical period of the respective wash program, if steam and / or moist air can escape through the door 3, the Suction unit 18 are activated to suck this exiting steam and / or these exiting moist air.

The extraction can be done only partially in critical areas. For the most effective possible extraction fresh air 24 can also be supplied, for example, in the lower corner area. This can be sucked from the environment or a pre-tempered area under the ground. An additional blower can be possible for this purpose.
