The dishwasher is designed such that the air outlet (14) is arranged in the lower quarter of the device height (H) and extends over at least two thirds of the width (Q) of the dishwasher (1) as a slot outlet, wherein at least one connection (26) located on the rear face is provided for introducing humid air into the air outlet (14), said connection being used to supply introduced air to an air distributor (16), which separates the supplied air into differently oriented sub-flows (19; 20).

Description

Dishwasher with at least one air outlet

The present invention relates to a dishwasher with at least one air outlet for blowing out, in particular, moist air from a washing compartment in which crockery, glasses, cutlery and similar items to be washed can be processed, according to the preamble of claim 1.

In dishwashers of this type, it is desirable for the items to be washed to be as completely dried as possible and to be able to be removed from the washing compartment without water stains.

For a good drying result for crockery, glasses, cutlery and similar items that can be processed in a washing compartment, it is advantageous for good drying to be able to remove moist air from the washing compartment. It is therefore known to connect the rinsing container to an air outlet which transports humid air out of the rinsing container to the outside environment. Such an air outlet is often located at the top of a front door that can be opened and closed. Supplying air to this moving unit is therefore relatively complex and expensive, and the high arrangement in the appliance also poses the risk of cabinets or worktops located above the dishwasher or parts of the dishwasher and their panels being damaged by the large amount of escaping moisture or that the kitchen floor in front of the dishwasher gets wet and therefore slippery. In addition, in the vicinity of such an air outlet, there is a significant draft phenomenon, which is very uncomfortable, especially in small kitchens where users sit close to a dishwasher.

The invention is based on the problem of achieving the greatest possible avoidance of water vapor impingement on surrounding furniture, the kitchen floor and front-side parts of the dishwasher with an attractive optical arrangement.

The invention solves this problem with a dishwasher, in particular a household dishwasher, with the features of claim 1. Regarding Advantageous refinements and developments of the invention, reference is made to claims 2 to 12.

Insofar as spatial and/or local information is given within the scope of the invention, this should preferably be understood from the point of view that a user assumes when using and/or operating the household dishwasher according to the invention when it is installed or installed ready for operation.

Because, according to the invention, at least one air outlet is arranged in the lower quarter of the height of the appliance, the dishwasher itself is first acted upon when water vapor rises from the air outlet, so that part of the water can condense there and does not hit the furniture above. In addition, because the air outlet extends as a slot outlet over at least two-thirds of the width of the dishwasher, a wide distribution of the escaping moisture and mixing with the drier outside air in the room is achieved. The moist air escaping into the environment at the respective place of installation of the dishwasher is thus distributed, and high moisture penetration into the furniture at certain points is avoided. Drafts are also significantly reduced thanks to the good distribution width of the air. Due to the fact that at least one connection, in particular on the rear, is provided for conveying moist air into the air outlet, via which the introduced air can be fed to at least one air distributor, which divides the supplied air into differently aligned partial flows and divides them into the width or Transverse extension of the air outlet this, in particular distributed as evenly as possible, feeds, the large width of the air outlet can be used well for the air. The pre-division of the washing chamber air supplied via the inlet-side connection into the partial flows ensures that air can exit over the entire width of the air outlet into the space in front of the dishwasher.

In particular, the air distributor can be assigned to the connection on the inlet side and/or arranged downstream of it. It is arranged in front of the slit-shaped outlet duct of the air outlet. This air distributor preferably divides the washing chamber air flow conveyed to the connection into a partial flow on the left-hand side and a partial flow on the right-hand side. Here, the left-side partial flow in the left-side section and the right-hand partial flow fed into a right-hand partial section of an upwardly projecting air duct. Viewed in the direction of flow, this air duct is arranged in front of the slit-shaped blow-out duct of the air outlet. Viewed in the vertical direction, it is preferably lower than the air outlet. It preferably extends essentially over the same width as the exhaust channel. In particular, its upper end is connected to the entrance of the exhaust duct extending forward over its entire width (seen from the front). The air inlet with the connection is preferably provided approximately in the middle of the width extension of the air duct in its rear wall. The air duct projecting upwards can thus advantageously function as a condensation area. The hollow space of the air duct is preferably sealed airtight and/or watertight at its lower end, so that it forms a condensate collection tank in its lower area. In this way, the air distributor ensures that, viewed from the front, a partial flow on the left-hand side of the scavenging chamber air flow conveyed to the connection on the inlet side, the left-hand half of the air duct preceding the air outlet and protruding upwards and the left-hand half of the forward-reaching, extending in width or transverse direction of the air outlet and a right-side partial flow of the flushing chamber air flow conveyed to the inlet-side connection acts on the right-hand half of the upwardly projecting air duct and the adjoining, right-hand half of the forward-reaching blow-out duct of the air outlet when the air inlet is connected to the connection for the Air supply line viewed in the transverse direction is provided in particular approximately centrally on the back of the upstanding air duct.

Preferably, the connection on the inlet side, the air distributor, the air duct projecting upwards, and the slit-shaped exhaust duct of the air outlet are components of an exhaust structural unit. This can in particular be designed in one piece or in one piece. It can preferably be made of plastic.

A blow-out unit designed in this way can be conveniently mounted on a front panel, in particular a base panel, which preferably closes off any existing base recess space of the dishwasher except for an upper gap that remains free. To do this, the air duct that rises upwards (when viewed from the front in the depth direction) is expediently installed behind the back of the front panel, in particular the plinth panel, arranged while the slit-shaped exhaust duct of its air outlet overhangs the upper edge of the front panel, in particular the plinth panel, in particular rests on it. The air duct is thus covered by the front panel, in particular the base panel, ie it is not visible from the front. Due to the slot shape of the exhaust duct, it is hardly noticeable from the front on the upper edge of the front panel. In particular, the air duct can be mounted—preferably releasably—on the back of the front panel, in particular the base panel. If the dishwasher has a plinth recess space, the exhaust assembly can be arranged so that its air duct comes to rest behind the plinth panel in the gap between the rear thereof and the front of the plinth of the dishwasher.

In particular, the partial flows are diametrically opposed to one another. They can then run from the air distribution to both transverse edges of the dishwasher and exit forwards along this path or in some cases only after reflection at an edge-side termination of the path.

Favorably, the air distributor is arranged at least almost centrally with respect to the extension of the air outlet in the width direction, so that the paths for both partial flows are approximately the same length and the air outlet to the front is also largely uniform across the width.

If the air distributor is held at least partially in a plane below the air outlet with respect to the vertical height of the dishwasher and conveys the air there directly into a duct that extends parallel to the air outlet, the particularly warm (washing room) air can escape from the duct upwards rise and exit from the air outlet. Any water that condenses can be held back in the channel and in particular run down through at least one outlet back into the dishwasher, so that the exterior space is kept largely free of moisture.

If the duct is open at the top and an upper edge of the duct adjoins the air outlet at an angle to the horizontally extending air outlet, the path for the warm air or warm, humid dishwashing room air into the room is very short. The escape of air that above the channel, which is only a few centimeters high, is carried out reliably and completely.

If the air outlet is at least 40 centimeters wide overall (in particular in relation to a household dishwasher with an appliance width of around 60 cm), a very broad and even distribution of the moisture and the exiting air can be achieved. The width of the air outlet can take up almost the entire width of the device in a particularly favorable manner.

In particular, the air outlet is designed as a flat slot outlet with a height-to-width ratio of less than 1:20, in particular between 1:20 and 1:200, preferably approximately 1:100. Despite the structurally and optically very low height, a high discharge surface can be achieved.

The air outlet is very advantageously arranged on the front side of the dishwasher facing the user and blows the air out with one component to the front. The air that is blown out is thus guided away from the kitchen furniture, and the accumulation of moisture in the installation space of the kitchen furniture is then avoided. The air that escapes there and is often laden with moisture can mix quickly and over a large area with the drier outside air in the kitchen.

If the air outlet overlaps a plinth cover that closes a plinth at the front and protrudes at least the same distance towards the front, the moist air can escape far enough to the front so that neither the kitchen floor nor the front of the dishwasher, in particular its front door, gets too wet pressurize The air stream can initially flow out at an initial speed in an approximately horizontal direction and, at a distance in front of the dishwasher, experience an increasing component due to its high heat.

Furthermore, after dismantling the plinth panel, the air outlet together with an air distribution upstream of it, which includes the air distributor and possibly preferably an upwardly projecting air duct preceding the air outlet, and a connection, in particular on the rear, can be removed together from the plinth (Be able to be moved out as a blow-out unit, and an excess-length air supply line, in particular a flexible connection hose or a corrugated pipe, which feeds the connection, can be retained in a mounted position. Assembly and disassembly are thus greatly simplified.

A high level of efficiency can be achieved if the air outlet can be controlled by at least one conveying element, such as a fan wheel, which is arranged in the lower area of the dishwasher in the depth direction behind the air outlet. The fan wheel or the like can then be approximately at the same height as the air outlet itself and can be arranged in the base of the dishwasher to save space.

The blow-out unit preferably comprises an air distribution duct, which protrudes upwards in its final assembly position and extends in the width direction, at the upper end of which the blow-out duct of the, in particular slot-shaped, air outlet, which extends to the front, is connected, and the one, in particular rear, connection for has an air supply line. In the final assembly position of the blow-out unit, the air distribution duct is therefore lower, viewed in the height direction, i.e. below the blow-out duct which projects forwards or protrudes, in particular in the form of a slot. In the final assembly position of the blow-out unit, it is advantageously arranged in particular behind the front base panel of the dishwasher. In particular, it is releasably mounted on the rear wall. Preferably, the cavity of the air distribution duct is sealed airtight and/or watertight at its lower end, so that it forms a condensate collection tank in its lower area. In its preferably rear air inlet, the air distributor duct has the air distributor for splitting the supplied air flow into the two partial flows, in particular a left-hand and a right-hand partial flow.

In particular, the blow-out unit, which includes the blow-out duct, the air distribution duct arranged upstream of the blow-out duct and projecting upwards, the air distributor in the air inlet of the air distribution duct, preferably on the rear, and the connection for the air supply line, is designed in one piece or in one piece, i.e. it forms a single component . This greatly simplifies their assembly/disassembly. It is preferably made of plastic, in particular by plastic injection molding. If washing chamber air is blown out of the washing chamber of the washing container by means of the blow-out unit to the outside, i.e. into the environment at the respective installation or installation location of the household dishwasher designed according to the invention during at least one drying phase, the drying phase preferably remains around a lower one, aligned in the transverse or width direction , Horizontal pivot axis pivotable front door of the household dishwasher in particular, ie closed. This prevents moist washroom air from the opening gap between the upper part of the front door and the washing container rising upwards and leaving condensate from the warm, humid washroom air flowing out on kitchen furniture parts located above the opening gap, such as a kitchen worktop, which can lead to moisture damage there could. It is also possible to avoid uncontrollable and/or excessive heat losses from the washing compartment of the washing compartment into the environment, which would be associated with a gaping door opening, which would impair the drying efficiency of the respective drying phase. In addition, by keeping the front door closed during the respective drying phase, it is possible to prevent dirt particles such as dust particles and/or germs and/or other foreign bodies from the environment from getting into the washing compartment onto the items to be washed that have previously been rinsed clean with the washing liquid. Finally, the fact that the front door remains closed also largely prevents operating errors and/or misinformation, which could be caused to the user by a front door that is open a crack. Thus, a user often incorrectly interprets a front door that is ajar as the end of a dishwashing program, although the drying phase that concludes the program has not yet ended.

The household dishwasher designed according to the invention provides, in particular, one or more dishwashing programs in which the items to be cleaned in the washing chamber of the washing compartment of the household dishwasher are exposed to washing liquid or washing liquor in one or more liquid-carrying partial washing phases, such as a pre-washing phase, cleaning phase, intermediate washing phase, final-rinse phase, and then be dried in a spülprogramm final drying phase with the front door remaining closed by means of the blow-out unit according to the invention, to then completely dry and can be removed from the wash tank after opening the front door without any water stains. If necessary, the end of the drying phase of the respective dishwashing program can be followed by a so-called "storage function phase" or storage phase for a predetermined period of time, until the end of which one or more additional drying phases are used to ensure that the items to be washed are washed while the front door of the household dishwasher remains closed remain dry in the washroom. This "storage function phase" can preferably extend over several days. In addition to or independently of this, other operating functions of the domestic dishwasher can also be provided by the blow-out unit according to the invention. For example, an odor elimination program can be implemented in which the air in the washing chamber is blown out into the vicinity of the domestic dishwasher by means of the blow-out unit and fresh air is sucked into the washing chamber if there is a risk of bad odors forming in the washing chamber. This can happen, for example, if, after the end of the last dishwashing program and the removal of the clean and dried items to be washed, soiled items to be washed are again placed in the washing compartment of the washing container and then stored for a longer period of time in the washing compartment of the washing container with the front door closed until the next dishwashing program is started.

A favorable further development of the invention provides that the fan wheel or a similar conveying element can be controlled in a clocked or continuous manner, namely during the drying phase of the respective dishwashing program and/or also beyond the end of this drying phase over a period of several days. In the latter case, the domestic dishwasher can advantageously serve as storage furniture or storage for items to be washed, such as crockery, glasses, cutlery and the like, and these items to be washed and dried beforehand during the respective dishwashing program can be dried again and again in phases or continuously over a period of several days. In this case, the front door of the domestic dishwasher preferably remains closed both during the regular drying phase of the respective dishwashing program to be carried out and during a possible subsequent "storage function phase". This storage of items to be washed in the washing compartment of the washing compartment, preferably with the front door remaining closed, immediately after the end of the The drying phase of the previously executed dishwashing program is referred to as the "storage function phase". The conveying element can be controlled both for its operation during the drying phase of the respective dishwashing program and during any subsequent "storage function phase", if necessary via a moisture detection in the washing chamber of the washing container.

Further advantages and features result from the exemplary embodiments of the subject matter of the invention which are illustrated in the drawing and described below.

5 shows a detailed view roughly corresponding to detail V in FIG. 4,

6 shows a schematic side view of the front area of the dishwasher with the installation position of the air outlet and the resulting air flow that is blown out to the front. The domestic appliance shown schematically in FIG. 1 is a dishwasher 1 here, specifically a domestic dishwasher. Other household appliances 1 with a drying function for the material to be processed can also be considered in principle for an embodiment according to the invention.

The domestic dishwasher 1 described below according to FIG. The items to be washed can be held, for example, in crockery baskets 11 and/or a cutlery drawer 10 and can be acted upon by so-called washing liquor. Washing liquor is understood to mean water that is fresh or, in particular, water that is circulating during operation, with or without cleaning agent and/or rinse aid and/or drying agent. In particular, the washing liquor has passed through an ion exchanger for softening. The rinsing liquor can also contain more or less dirt from ongoing operations. The washing container 2 can have an at least essentially rectangular outline with a front side V facing a user in the operating position. This front side V can form part of a kitchen front made of kitchen furniture standing next to one another or, in the case of a stand-alone appliance, can also be unrelated to other furniture.

The washing compartment 2 can be closed by a front door or flap 3 in particular on this front side V. This door 3 is shown in FIG. 1 in a partially open position and then in a position at an angle to the vertical. In its closed position, however, it stands upright and, according to the drawing, can be pivoted forwards and downwards in the direction of arrow 4 to its opening around a lower horizontal axis, so that it is at least almost horizontal in the fully open position.

The front door 3 can be provided with a decorative panel 6 on the outside and front side V of the dishwasher 1, which is vertical in the closed position and faces the user, in order to experience a visual and/or haptic enhancement and/or an adaptation to the surrounding kitchen furniture. The household dishwasher is designed here as a stand-alone or as a so-called partially integrated or fully integrated device. In the latter case, the appliance body 5 can also essentially end with the outer walls of the washing container 2 . A housing surrounding this on the outside can then be dispensed with. In the lower area of the household dishwasher there is a base 12 on which the washing container 2 is mounted and which is used in particular to accommodate functional elements of the household dishwasher, such as a pump for circulating the washing liquor, a drain pump, a pump sump, a control unit, etc... . In this base 12 itself or, as here in the exemplary embodiment, in its front-side recess space, an air outlet 14 described below is provided, which partially overlaps a front panel 15 towards the front side V that optically closes the base or the base recess space at the front.

In the exemplary embodiment according to the drawing, the movable front door 3 is assigned in its upper area a front control panel 8 which extends in the transverse direction Q of the domestic dishwasher and which can include an access opening 7 accessible from the front V for manually opening and/or closing the door 3. In the transverse direction Q, the domestic dishwasher often extends 45, 50 or 60 centimeters. In the depth direction T from the front V to the rear, the extension is often also around 60 centimeters. The values are not mandatory. The household dishwasher 1 does not have to stand directly on a floor B, such as a kitchen room, but can also be installed approximately at eye level within a piece of kitchen furniture, so that the initially mentioned problem of drafts through an air outlet 14 must be given particular attention. In a domestic dishwasher that can be fully integrated, the front control panel 8 in the upper area of the front door is omitted and replaced by a control panel in the upper edge of the front door. Other arrangements of the control panel on and/or in the front door are also possible. If necessary, the control panel can be omitted entirely, for example if the operation of the household dishwasher can be controlled and/or monitored using a mobile communication device such as a smartphone. When the front door or flap 3 is closed, the washing chamber of the washing compartment 2 is delimited all around by three fixed vertical walls 13 and two horizontal walls 13, one of which forms a top (top) and another a bottom (bottom) of the washing compartment 2. A left upright side wall 13 adjoins the front side V facing the user in the transverse direction Q to the left and a right upright side wall 13 to the right.

The wall 13 forming the base of the washing compartment 2 and delimiting it essentially downwards lies approximately horizontally above the base 12, ie parallel to an outer floor B on which the dishwasher 1 can stand. A higher installation, for example at the height of a worktop, is also possible, as mentioned, in particular within a cupboard. The lower edge of the dishwasher 1 is then approximately 70 to 110 centimeters above the floor in the installed position.

The dishwasher 1 is provided with at least one air outlet 14 for blowing out, in particular, humid air from the washing container 2 . This air outlet 14 can blow air, in particular moist air, out of the washing compartment of the washing compartment into the free air space on the front side V of the dishwasher 1 facing a user, so that the moist air is not introduced inside a kitchen unit and could cause damage there due to moisture. The blowing out of in particular humid washing room air by means of the air outlet 14 preferably takes place during the program-final drying phase of a dishwashing program to be carried out and/or during at least one additional drying phase of a chronologically subsequent “storage function phase”. In any case, the front door 3 remains closed.

The air outlet 14 is part of a blow-out unit 15, which is shown overall in FIG. 2 by way of example. The blow-out unit 15 comprising the at least one air outlet 14 extends over at least half the width Q of the dishwasher 1, in particular more. A particularly uniform distribution of the exiting air can thus be achieved, so that the phenomenon of drafts is minimized. The blow-out unit 15 can be made entirely of plastic. Furthermore, the air outlet 14 can be divided into a plurality of partial slits lying flush next to one another. They don't all have to be the same length. It is important that a broad air outlet 14 is created overall, which enables a high air throughput in order to achieve a broad distribution of the moisture contained in the air.

The air outlet 14 is arranged here in the lower quarter of the height of the appliance and extends as a one-part or multi-part slit outlet over at least half, in particular over at least two thirds, of the width Q of the dishwasher 1. In particular, the air outlet 14 is at least 40 centimeters (in particular with a household dishwasher with a device width of 60 cm). As can be seen clearly in FIGS. 2 and 3, it can also extend over almost the entire width Q of the dishwasher 1. At least one connection 26 of the blow-out unit 16 is provided for conveying moist air from the washing chamber of the washing compartment 2 into the air outlet 14 - here preferably on the back of the air outlet 14 . The rinsing chamber air introduced through this connection 26 can first be supplied to an air distributor 16 which protrudes into the cross section of the connection 26, which is tubular in this case, and divides the air flow 17 approximately in the middle. In particular, the beginning of the air distributor 16 forms a narrow, upright rib 18, to the left and right of which partial flows 19, 20 are formed.

The rib 18 transitions into a curved air guiding element 21 which, with its end facing away from the rib 18 , protrudes into an air distribution channel 22 which is arranged behind the air outlet 14 (ie facing away from the front side V). The duct 22 has a considerably greater height than the air outlet 14 and can have drains for condensed water on its underside—not shown here. The channel 22 is preferably sealed airtight and/or watertight at its lower end, so that it has a condensate collection tank in its lower area.

The air guide element 21 widens in the air distribution duct 22 in plan view similar to a triangle with rounded sides and extends to a front duct wall 23. This ensures that the partial flows 19, 20 formed in the duct 22 do not mix again. Rather, the partial flows 19, 20 in the channel 22 are diametrically opposed to one another and run from the air distributor 16, which is ideally in the middle with respect to the transverse direction Q, to almost both outer walls of the dishwasher 1. The partial flows 19, 20 have a sufficiently high speed to move on their opposite paths to maintain approximately uniform density through the duct 22 before the air is allowed to exit therefrom with an upward and forward component, as described below:

The above Channel 22 extends parallel to the air outlet 14 in the width direction Q of the dishwasher 1. The air distributor 16 is held at least partially in a plane below the air outlet 14 with respect to the vertical height H of the dishwasher 1, as is the channel 22 into which the air distributor 16 is funded. The air from the air distributor 16 therefore does not escape directly through the air outlet 14, but first passes through the duct 22 in both directions with its partial flows 19, 20. As air continues to be conveyed in, the air in the duct 22 that is open at the top is pushed out upwards again and again and, because of the upper baffle 24 , then only has the chance to flow laterally and forwards into the air outlet 14 .

This is possible because the duct 22 is open at the top and an upright front duct wall 23 adjoins the horizontally extending air outlet 14 at an angle, which ideally has the same extent in the width direction Q as the duct 22, in particular at least 40 centimeters.

In particular, the—single or multi-part—air outlet 14 according to FIG. Then, with an air outlet 4 that is 40 centimeters wide, its height in the vertical direction H is less than about 2 centimeters. It is then ensured that, on the one hand, it takes up little installation space in the height direction H, and, on the other hand, the overall extent of the air outlet 14 is large enough to discharge a large volume of air and thus keep the draft very low. In order to avoid moisture damage from the moist air blown out, the air outlet 14 is arranged on the front side V of the dishwasher 1 facing a user and blows the air out forward with a component such that the air does not rise directly, but due to its initial speed up to at least carried a few centimeters in front of the device before an ascending component takes effect because the air blown out is usually warmer than the surrounding room air (Figure 6).

As can also be clearly seen in FIG. 6, the air outlet 14 can overlap a base panel 5 closing off a base 12 to the front and project at least the same distance towards the front side V in relation to this panel. The base 12 with its front panel 5 can set back a few centimeters compared to the front door 3, but moistening of the lower edge of the front door 3 and in particular the lower edge of any front-mounted decorative panel or furniture panel such as 6 can be avoided by the forward-pointing component of the air outlet velocity will. In addition, an upper guide 25, for example an upper wall, of the air outlet is arranged at a slight angle in such a way that the escaping air is blown out a few degrees downwards into the room. The air outlet is therefore not completely horizontal, but can be carried out through the downward component under the door 3 without causing moisture damage there. The wide extension of the air outlet 14 prevents a disturbing draft.

After a possible dismantling of the plinth panel 5, the air outlet 14 can be moved out of the plinth 12 together with the air distribution fluidically upstream of it, which in particular comprises the duct 22 and the air distributor 16, and the rear connection 26 as a blow-out unit 15 an excess-length air supply line, in particular a flexible connecting hose or a corrugated pipe, which supplies air from the washing chamber of the washing container to the connection 26, can remain in a mounted position. This is particularly easy to maintain. The air supply line LZ is indicated by dots in FIG.

For sucking off rinsing room air from the rinsing area of the rinsing container and blowing out this rinsing room air by means of the blow-out unit can be in or in front of it Connection 26 at least one conveyor element such as a fan may be provided, which can also be controlled in a clocked manner, even over a period of several days. In FIG. 2, an air conveying element LF, such as a fan, is inserted in the air supply line LZ. It is only shown schematically in FIG. 2 as a dotted rectangle. The air supply line is connected with its upstream end to an air outlet opening which is provided in one of the boundary walls of the washing chamber, in particular in a wall, preferably a side wall, of the washing container.

A dishwasher with the following advantageously designed blow-out unit 15 for mounting on a plinth panel 5, in particular floor plinth panel, can be advantageous in particular:

In particular, the air distributor 16 of the blow-out unit 15 is assigned to the connection 26 on the inlet side and/or arranged downstream of this in the direction of flow. It is arranged in front of the slit-shaped exhaust channel of the air outlet 14 . This air distributor 16 preferably divides the rinsing chamber air flow conveyed to the connection 26 into a partial flow on the left and a partial flow on the right. The left-hand partial flow is fed into the left-hand section and the right-hand partial flow is fed into a right-hand partial section of the air duct 22 protruding upwards. This air duct 22 is arranged in front of the slit-shaped blow-out duct of the air outlet 14 when viewed in the direction of flow. Viewed in the vertical direction, it is preferably lower than the air outlet. It preferably extends essentially over the same width as the exhaust channel. In particular, its upper end is connected to the entrance of the exhaust duct extending forward over its entire width (seen from the front). The air inlet with the connection 26 is preferably provided approximately in the middle of the width extension of the air duct 22 in its rear wall. The upwardly projecting air duct 22 can thus advantageously function as a condensation area. The hollow space of the air duct 22 is preferably sealed airtight and/or watertight at its lower end, so that it forms a condensate collection tank in its lower area. In this way, the air distributor 16 ensures that, viewed from the front, a partial flow on the left-hand side of the scavenging chamber air flow conveyed to the connection 26 on the inlet side follows the left-hand half of that which precedes the air outlet 14 air duct 22 projecting upwards and the left-hand half of the air outlet 14 reaching forwards and extending in the width or transverse direction, and a partial flow on the right-hand side of the washing chamber air flow conveyed to the connection 26 on the inlet side, the right-hand half of the air duct projecting upwards and the applied to this adjoining, right-side half of the blow-out duct of the air outlet 14, which extends forward, if the air inlet with the connection for the air supply line is provided, viewed in the transverse direction, in particular approximately centrally on the rear side of the air duct towering upwards.

Preferably, the connection on the inlet side, the air distributor 16, the air duct 22 projecting upwards, and the slit-shaped blow-out duct of the air outlet 14 are components of the blow-out unit 15. This can in particular be designed in one piece or in one piece. It can preferably be made of plastic.

The blow-out unit 15 designed in this way is - e.g. as shown schematically in a side view in Figure 6 - on a front panel 5, in particular a floor base panel, which preferably has any existing base recess space of the dishwasher except for an upper one, between the lower edge of any with a Decor or furniture panel stocked front door 3 and the top edge of the panel 5 free gap closes, cheap to assemble. For this purpose, its upwardly protruding air duct 22 (when viewed from the front in the depth direction) is expediently arranged behind the back of the front panel 5, in particular the base panel, while the slot-shaped exhaust duct of its air outlet 14 overhangs the upper edge of the front panel 5, in particular the base panel, in particular on it rests. The air duct 22 is thus covered by the front panel 5, in particular the base panel, ie it is not visible from the front. Due to the slot shape of the exhaust duct, this is hardly noticeable from the front on the upper edge of the front panel, especially on the floor or base panel. In particular, the air duct 22 - as here in the embodiment of Figure 6 - on the back of the front panel 5, in particular base panel, - preferably releasably mounted. In the case of a floor plinth panel - as shown in Figure 6 - this stands on the floor B on. A dishwasher 1 designed according to the principle according to the invention can not only carry out the final drying phase of a respective dishwasher program to be carried out, but can also be provided with a so-called "storage function" if required, which makes it possible for the items to be washed to be stored in the washing compartment 2 after processing remains without getting wet again. This retention can last for several days without the dryness of the items to be washed deteriorating. The dishwasher 1 then also serves as a storage and drying cabinet from which the items to be washed can be removed fresh and dry.

In particular, for the "storage function" the conveying element can be controlled in a clocked manner. Alternatively and particularly effectively, the conveying element is controlled via a moisture sensor system, which provides a measure of the current moisture content of items to be washed in the washing compartment.

In both cases, the conveyor element is only switched on every now and then in order to repeatedly convey moist air out of the washing container 2 and thus to preserve the quality of the cleaning of the items to be washed, even over a longer period of time. Due to the only low effective running times, the energy requirement is low—as is the noise level from the at least one fan wheel or similar conveying element.

However, it may also be advantageous if the conveying element is operated continuously with air to be blown out, in particular washing room air, during the drying phase of the respective dishwashing program and/or during the entire duration of any subsequent "storage function phase" and/or another operating phase of the household dishwasher .
