Abstract

A domestic dishwasher (1) has at least one air outlet (14) for blowing air, in particular moist air, from a washing tub (2) in which cookware, glasses, cutlery and the like can be treated, is designed in such a way that a structural unit (15) comprising the at least one air outlet (14) extends over at least half the width (Q) of the domestic dishwasher (1) and comprises in the upper region of the domestic dishwasher an extended, slit-shaped blow opening (16) and in the lower region of the domestic dishwasher a collecting trough (17) for condensate.

Description

TECHNICAL FIELD

[0001] The invention, according to the preamble, relates to a domestic dishwasher having at least one air outlet for blowing air, in particular moist air, out of a washing tub in which cutlery, glasses, tableware and similar washware can be processed. BACKGROUND

[0002] It is desirable in such a domestic dishwasher that the washware is dried as completely as possible and can be removed from the washing tub without water spots. At the same time, the loading of the floor or the surrounding kitchen furniture on which the domestic dishwasher stands with moisture should be kept as low as possible.

[0003] For a good drying result of the cutlery, glasses, tableware, etc. that can be processed in the washing tub, it is desirable that the moist air can be removed from the washing tub. It is therefore known to connect the washing tub to an air outlet which transports the moist air from the washing tub into the outside environment. The air outlet is therefore usually located in the upper region of a front side door or front door which can be opened and closed. The transport of air into this mobile unit is therefore relatively costly and expensive. Furthermore, due to the arrangement of the device high up, there is a risk that cabinets or worktops or also other kitchen furniture located above the domestic dishwasher are damaged by the large amount of moisture exiting. SUMMARY

[0004] The purpose underlying the invention is to achieve a good drying of the washware with a minimum of influence on the furniture, floor or other areas adjoining the domestic dishwasher.

[0005] The invention solves this problem by means of a domestic dishwasher having the features of the invention, which can be realized individually or in combination with one another. Advantageous design solutions and refinements of the invention are described with reference to the embodiments.

[0006] In the design according to the invention, by virtue of the fact that the structural unit comprising the at least one air outlet extends over at least half the width of the domestic dishwasher and comprises in the upper region of the domestic dishwasher an extended, slit-shaped blow opening and in the lower region of the domestic dishwasher a collection trough for condensate, on the one hand the distribution of the blown, usually moist air over a large area is ensured by the slit-shaped blow opening, so that a point-like, high water load is avoided. On the other hand, by means of the collection trough in the lower region it is ensured that the condensate remains largely in the structural unit and can flow down back into the collection trough without exiting from the air outlet and without wetting the surrounding furniture or floor.

[0007] Furthermore, a wide distribution of the exiting, moisture-laden and / or water-vapor- containing wash chamber air is achieved by the air outlet extending as a slotted outlet over at least half the width of the household dishwasher, in particular of the base carrier. To this end, the slotted outlet preferably has a large slot width and a small slot height associated therewith. The wash chamber air flowing out of the wash chamber of the wash container is thus distributed over a plurality of exit sites along the width of the slotted outlet. It is avoided that a point-like, i.e. locally concentrated, wash chamber air volume flow is generated, as is the case at the output end of a displaced air outlet in a household dishwasher having only a single air outlet with an approximately circular passage cross section, and that a point-like high moisture input is generated in the furniture by the wash chamber air volume flow. In particular, the moist and / or water-vapor-containing wash chamber air can be finely distributed over a larger area outside the household dishwasher according to the application, so that the wash chamber air can be mixed with the comparatively dryer ambient air of the environment more improved, wherein the wash chamber air is blown out of the slotted outlet extending over at least half the width of the household dishwasher. The moisture and / or water vapor contained in the wash chamber air blown out of the slotted outlet over at least half the width of the household dishwasher according to the application can be better absorbed by the ambient air. Thus, viewed over the width of the slotted outlet, in particular, only a reduced volume flow of moist and / or water-vapor-containing air of the interior of the dishwasher escapes locally at each point of the slotted outlet compared to the volume flow of the wash chamber air, the wash chamber air flowing out of the locally or at certain points defined single (e.g. circular) slotted outlet into the surroundings of the household dishwasher installation site in a concentrated manner (with the same total throughput of wash chamber air). By means of the slotted outlet according to the application, a local dilution of the wash chamber air from the wash chamber of the wash container and the moisture content contained therein in the ambient air is ensured. In this way, it is possible to reduce or even largely avoid that condensate droplets coalesce into larger liquid droplets and that the liquid droplets then flow down or drip from the air outlet onto the floor at the installation site of the household dishwasher. Furthermore, the blown-out wash chamber air is distributed over at least half the width of the household dishwasher, in particular of the front door, in the manner generated by means of the slotted outlet, if necessary even so small that the volume flow of the blown-out wash chamber air of each exit slot site is so small that the wash chamber air blown out in a locally distributed manner along the width of the exit slot is hardly or only insignificantly perceptible to a user of the household dishwasher.

[0008] The output passage cross section is advantageously smaller, in particular significantly smaller, than the input passage cross section of the air outlet according to the application. This leads to an increase in the flow speed of the wash chamber air blown out of the slotted outlet into the environment relative to the flow speed of the wash chamber air upstream before entering the slotted outlet. This further reduces the risk of undesirable condensate accumulation and water droplets on the output side of the slotted outlet.

[0009] According to the constructive solution of the application, a modular flexible construction of the structural unit comprising at least one air outlet is ensured. By virtue of the functions realized there, namely ensuring an extended condensation area at the structural unit extending in the width direction of the device and at least one blowing opening extending therefrom to the front side of the domestic dishwasher and an input opening into the condensation area in the rear side, a high condensate collection capacity and high functionality are achieved. The structural unit can be positioned differently in the depth direction of the domestic dishwasher and can also be clad below the extended blowing opening by means of different, in particular differently high, panels.

[0010] In particular, the structural unit comprising at least one air outlet is integrally constructed with the blowing opening and at least one input opening and the condensation area, so that it can be easily assembled and inexpensively manufactured as a whole unit.

[0011] Here, it is particularly advantageous that the structural unit comprising at least one air outlet is integrally constructed and can be inexpensively and quickly manufactured, for example, in an injection molding method or similar.

[0012] If the air outlet is preferably at least 40 cm in overall width, good distribution of the moist air is ensured, and the likelihood of water dripping at certain points is very small.

[0013] In particular, the air outlet is constructed as a flat slotted outlet, which has a height-to-width ratio of less than 1:10, in particular advantageously a height-to-width ratio of less than 1:20. Despite the very low structural and visual height, a high discharge surface can thereby be achieved.

[0014] For high mechanical stability and intervention safety, the air outlet can be divided into a plurality of side-by-side aligned sub-slits, for example into two to three sub-slits side by side with each other, which each comprise a reinforced vertical web as a stable partition from each other.

[0015] If the air outlet is arranged on the front side of the domestic dishwasher facing the user, the air leaving there and usually loaded with moisture can be distributed quickly and over a large area in the surrounding space.

[0016] By means of a minimized structural space expenditure, the air outlet is arranged such that the structural unit comprising it is arranged at the lowermost end of the front side of the domestic dishwasher, in particular at the front of the base. Here, a cladding of the front side is usually attached in any case. Since the structural unit is very flat constructed (preferably less than 5 cm) beyond the extended blowing opening and the connecting flange for the air input in the rear side, only very little space is required in the depth direction.

[0017] If the structural unit preferably extends over the entire width of the front side of the domestic dishwasher, this is advantageous for air distribution and for a straight, continuous design.

[0018] Furthermore, the air outlet can project forward with respect to the other outer wall portions of the structural unit toward the front side, such that the blow-out opening is directed further forward than the outer wall portion of the front of the condensation region, in particular by several centimeters. This is provided in particular in a recessed base, since the air outlet then occupies the originally unused space at the upper end of the base under the door. Since the blow-out opening is located at the top of the upper end of the structural unit, condensation water can also flow back into the structural unit downward, thereby further reducing the risk of dripping.

[0019] By means of its (preferably approximately horizontal) forwardly directed overhang, the air outlet can advantageously be arranged, in particular attached, on the upper edge of the base plate or base and leg strip. If the structural unit according to the application is completed in accordance with this advantageous embodiment at the base plate, its air outlet with its lower edge of the forwardly directed overhang is preferably seated on the upper edge of the base plate; its condensation region, which preferably extends vertically, is arranged behind the base plate. Irrespective of the height of the base plate or base strip, the structural unit can thus be positioned in an assembly-friendly, simple manner at the base plate or base strip, such that it is always ensured that the blow-out opening is arranged above the upper edge of the base plate and thus enables the air to be blown freely out of the rinsing container. It is thus always avoided that the base plate arranged in front of the structural unit obstructs the blow-out path of the air from the blow-out opening in the air outlet.

[0020] For a simple design and uniformity of the air discharge in the width, the blow-out opening can advantageously in particular have a constant height over its width extension.

[0021] Furthermore, the condensation region can in particular exhibit a constant depth, wherein a face plate can advantageously be arranged upstream of the condensation region toward the front side in order to achieve a uniform design with other kitchen furniture.

[0022] If the blow-out opening is formed as a very narrow gap between the upper lip and the lower lip and the lower lip extends continuously upward from the condensation region to the blow-out opening, dripping can be very effectively avoided. The water formed over the entire area up to the blow-out opening can then reliably return into the structural unit and the collection trough without reaching the environment. There, in the stationary phase of the domestic dishwasher, the possibly collected water can then evaporate.

[0023] Also very effective in this design is that the upper lip has a drip edge at its side facing downwards, which is arranged above the lower lip. Water formed at the drip edge thus reliably falls onto the lower lip when dripping and can flow back without reaching the outside. To this end, the lower lip preferably protrudes further in the direction of the front side of the domestic dishwasher than the upper lip.

[0024] In order to be able to convey moist air from the rinsing container to the air outlet, an air channel, in particular a few decimetres long, can be provided upstream of the structural unit from the rinsing container, which can be flexibly connected to the input of the structural unit. The structural unit thus does not have to be precisely matched in the depth direction, but can be flexibly assembled. Retrofitting of existing systems is also possible.

[0025] To this end, the air channel can in particular have a variable length up to the connection to the input of the structural unit and for example at least locally constitute a bellows hose.

[0026] If the air outlet can be actuated by at least one conveying means, for example a fan wheel, and thus air is conveyed from the rinsing container to the air channel, a high efficiency can be achieved.

[0027] It is very advantageous to provide the air channel, in particular a few decimetres long, from the rinsing container upstream of the slot-shaped air outlet. A large part of the condensation can thus already be performed in a manner distributed in the long air channel.

[0028] If the slot-shaped air outlet can be driven by at least one air conveying means, for example a fan wheel, that is, can be supplied with wash chamber air from the wash chamber of the washing container, a high efficiency can be achieved. The air conveying means is preferably fluidically connected on the upstream side via an air channel to at least one air outlet opening of the at least one air outlet opening or inner door of the front door of the washing container. On the downstream side, an air discharge channel or air blowing channel preferably leads from the air conveying means to the slot-shaped air outlet. If the air conveying means is activated, that is, switched on, the wash chamber air from the wash chamber of the washing container is drawn by the air conveying means via the air channel on the upstream side to the air conveying means and is then blown by the air conveying means through the air discharge channel on the downstream side to the air outlet. The air conveying means can preferably be arranged behind the air outlet in the depth direction in the lower region of the domestic dishwasher. The fan wheel or the like can then be arranged approximately at the same height as the air outlet itself and in a space-saving manner in the base carrier or base of the domestic dishwasher. For this purpose, the air channel very advantageously begins in the wall of the washing container in the upper 50%, in particular 30%, of the washing container height, thereby forming a long path for possible condensate. The air channel can in particular be at least 40 cm long. Furthermore, it is advantageous if the air channel first extends upward from its starting point at the air outlet opening in the wall or front door of the washing container, so that possible condensation water can flow back into the washing container and does not remain in the air channel.

[0029] If the air outlet can be driven by at least one air conveying means, for example a fan wheel, that is, can be supplied with wash chamber air from the wash chamber of the washing container, a high efficiency can be achieved. The air conveying means is preferably fluidically connected on the upstream side via an air channel to at least one air outlet opening of the at least one air outlet opening or inner door of the front door of the washing container. On the downstream side, an air discharge channel or air blowing channel preferably leads from the air conveying means to the slot-shaped air outlet. If the air conveying means is activated, that is, switched on, the wash chamber air from the wash chamber of the washing container is drawn by the air conveying means via the air channel on the upstream side to the air conveying means and is then blown by the air conveying means through the air discharge channel on the downstream side to the air outlet. The air conveying means can preferably be arranged behind the air outlet in the depth direction in the lower region of the domestic dishwasher. The fan wheel or the like can then be arranged approximately at the same height as the air outlet itself and in a space-saving manner in the base carrier or base of the domestic dishwasher. For this purpose, the air channel very advantageously begins in the wall of the washing container in the upper 50%, in particular 30%, of the washing container height, thereby forming a long path for possible condensate. The air channel can in particular be at least 40 cm long. Furthermore, it is advantageous if the air channel first extends upward from its starting point at the air outlet opening in the wall or front door of the washing container, so that possible condensation water can flow back into the washing container and does not remain in the air channel.

[0030] Especially advantageously and claimed separately is that the blowing or exhaust channel extends between the at least one (air) transport means and the air outlet, the blowing or exhaust channel being configured in a cross-section-reducing manner with respect to the air channel, wherein the air channel leads from the air outlet opening in a wall portion, in particular a side wall portion, of the rinsing container or in an inner door wall portion of the front door to the transport means. By the reduced cross-section, the speed of the rinsing chamber air drawn out of the rinsing chamber of the rinsing container by means of the transport means is increased in the blowing channel with respect to the flow speed of the rinsing chamber air in the rinsing chamber of the air channel before the transport means, so that only a small amount of condensation is produced in the region near the air outlet behind the transport structure, too, and the risk of dripping of water from the air outlet is thereby minimized.

[0031] An advantageous refinement of the application proposes that the fan wheel or a similar transport element can be actuated in a clocked manner, also during a multi-day period. Here, too, actuation can take place via a moisture detection device of the rinsing container. The domestic dishwasher can then also be used as a storage for cookware, glasses, cutlery, etc. and these previously rinsed items are always re-dried here in stages over a multi-day period.

[0032] Thus, the blowing out of rinsing chamber air from the domestic dishwasher according to the application via its slotted outlet can not only be carried out during the drying phase of the rinsing phase of at least one dishwashing program to be executed, but, if necessary, additionally in a temporally later manner after the end of the drying phase of the rinsing phase, during one or more subsequent drying cycles for the subsequent drying of rinsed items stored in the rinsing container. Such a re-drying can be desired if the door is not opened immediately after the end of the drying phase of the rinsing phase of the respective executed dishwashing program by the user or an automatic door opening system, but remains closed for a longer duration, in particular for at least 6 hours up to days, i.e. for example up to 96 hours. The saving of rinsed items in the rinsing chamber of the rinsing container in the case of a closed door after the end of the drying phase of the executed dishwashing program is referred to as "storage function". Here, in order to keep the rinsed items in the rinsing container dry or to avoid their renewed moistening, the at least one air transport means is activated from time to time for a certain duration, respectively, in order to cause a re-drying of the rinsed items in the rinsing container by air exchange of the rinsing chamber air by ambient air or in order to largely avoid a renewed moistening of the rinsed items and then deactivated again.

[0033] Further refinements of the application are explained in the embodiments.

[0034] The above-explained and / or in the embodiments described advantageous configurations and refinements of the application can be used individually, but also in any desired combination with one another, hereinafter. BRIEF DESCRIPTION OF DRAWINGS

[0043] Figure 1 The domestic appliance shown schematically in

[0044] The following described embodiments of the application are based on a domestic dishwasher 1, more precisely a domestic dishwasher. In principle, other domestic appliances 1 with a drying function for items to be treated can also be considered for the configuration according to the application. Figure 1A domestic dishwasher 1 has a rinsing container 2 for accommodating rinsing objects to be treated, such as cookware, pots, tableware, glasses, cooking utensils, etc., as a component part of a partially outwardly opening or closing device body G. Here, the rinsing objects can be held, for example, in a cookware basket 11 and / or a tableware drawer 10 and here a so-called rinsing liquid can be applied. Here, the rinsing liquid is understood to be clear water or, in particular, water circulating in operation, with or without cleaning agent and / or dishwashing agent and / or drying agent. In particular, the rinsing liquid has ion exchangers for softening. The rinsing liquid can additionally also be more or less detached from the current operation together with the dirt. The rinsing container 2 can have an at least substantially rectangular profile with a front side V facing the user in the operating position. Here, the front side V can be formed by a part of a plurality of kitchen furniture kitchen fronts side by side, or in the case of a stand-alone device, the front can also be associated with no other furniture.

[0045] The rinsing container 2 is closed in particular at the front side V by a front door or flap. The door 3 is shown in a partially open and inclined position to the vertical in Figure 1 However, in its closed position, the door stands upright and can be pivoted about a lower horizontal axis according to the drawing in the direction of the arrow 4 to open it so that the door is at least almost horizontal in the fully open position.

[0046] The door 3 can be provided at its outer side and front side V facing the user in the closed position of the domestic dishwasher with a decorative panel 6 in order to thereby achieve a visual and / or haptic enhancement and / or adaptation to the surrounding kitchen furniture.

[0047] The domestic dishwasher can be constructed as a stand-alone device or as a so-called partial or full integrated device. In the last case, the device body can also be substantially flush with the outer wall of the rinsing container 2. The housing surrounding the rinsing container externally can then be dispensed with. In the lower region of the domestic dishwasher there can be a base 12 for accommodating in particular functional elements, i.e. also a pump for circulating the rinsing liquid, and also an air outlet 14 to be described below.

[0048] In the embodiment according to the drawing, the movable front door 3 is associated in its upper region with an operating panel 8 extending through the transverse direction Q of the domestic dishwasher, which can comprise a handle recess 7 accessible from the front side V to open and / or close the door 3 manually. In the transverse direction Q, the domestic dishwasher typically extends 45, 50 or 60 centimeters. In the depth direction T, which is rearward from the front side V, it typically also extends approximately 60 centimeters. This value is not mandatory.

[0049] The rinsing container 2 is delimited circumferentially by three fixed vertical wall sections 13 and two horizontal wall sections 13, one of which forms the top (upper) portion of the rinsing container 2 and the other forms its bottom (lower) portion, when the front door or flap 3 is closed. The left standing side wall 13 in the transverse direction Q to the left and the right standing side wall 13 to the right adjoin the front side facing the user.

[0050] The wall section 13 forming the bottom of the rinsing container 2 and substantially delimiting the bottom downward is located approximately horizontally above the base 12, i.e. parallel to the outer bottom B on which the domestic dishwasher 1 can stand. Installation at a higher level, for example in the height of a worktop, is optional as mentioned, in particular in a cabinet. In the installed position, the lower edge of the domestic dishwasher 1 is at a height of approximately 70 to 1 10 cm above the floor.

[0051] The domestic dishwasher 1 is provided with at least one air outlet 14 for blowing out, in particular moist, air from the washing container 2. The air outlet is a component of a structural unit 15 which is shown exemplarily as a whole in Figure 2 . Here, the structural unit 15 comprising at least one air outlet 14 extends over at least half the width Q of the domestic dishwasher 1. According to the drawing, the structural unit 15 preferably extends over the entire width Q of the domestic dishwasher.

[0052] The structural unit 15 also has in its upper region a projecting, slit-shaped blow opening 16 and in its lower region a collecting trough 17 for condensate. In the assembled position, the blow opening 16 is directed toward the front side V of the domestic dishwasher 1 and projects a few centimetres relative to the front wall section 18 of the condensation region 19. On the rear side opposite the blow opening 14, an inlet opening 20 is provided which here exemplarily comprises a projecting flange of a push hose. The structural unit 15 comprises the mentioned functional components 14, 16, 17, 18, 19, 20, and if necessary 21, as a whole and can be preassembled modularly.

[0053] In the structural unit 15 comprising at least one air outlet 14, the condensation area 19 is configured as an inner cavity which extends significantly in the lateral direction Q of the device 1. In the depth direction T, on the other hand, the extension is very small in order to save space and is typically only about one to three centimeters. The front wall of the condensation area 19, which is in contact with the ambient air in the assembled position, can form a cooling surface and is provided, for example, with cooling ribs 21. In particular, the front wall 18 comprises a material with a high heat capacity. The front wall can be cooled simply by ambient air, by water or another material. The air blowing opening 16 which leads from there to the front side V of the domestic dishwasher 1 and the input opening 20 which leads into the condensation area in the rear are integrally included. The lower collection trough 17 can also be an integral component of the structural unit 15 and preferably extends over the entire width of the condensation area 19 in order to reliably collect the water formed there.

[0054] Here, the structural unit 15 comprising the air outlet 14 can be configured in particular integrally, for example from plastic.

[0055] In particular, for this purpose, the overall width of the air outlet 14 (integral or multipart) is at least 40 centimeters. According to Figure 2 , the air outlet is configured as a flat slotted outlet with a height to width ratio of less than 1:10, in particular less than 1:20. Thus, for example, in the case of an air outlet 4 which is 40 centimeters wide, its height in the vertical direction H is preferably less than about 2 centimeters.

[0056] As mentioned above, the air outlet 14 can be divided into a plurality of side-by-side flush sub-slits. The sub-slits do not necessarily all have the same length. What is important is that an overall wide extending air outlet 14 is created which achieves a high air throughput in order to thus also achieve a wide distribution of the moisture contained in the air.

[0057] As shown above and as can be seen in Figure 5 , the air outlet 14 is advantageously arranged on the front side V of the domestic dishwasher 1 which faces the user. The air outlet can then blow into the space in front of the domestic dishwasher 1 and here distributes the moisture well so that the moist air does not disappear into the interior of the built-in furniture and cause damage there.

[0058] According to the drawing, the air outlet 14 is preferably arranged such that the structural unit 15 surrounding it is arranged at the lowermost end of the front side V of the domestic dishwasher 1. In particular, the structural unit 15 is fixed at the front end of the base 12 and can itself be covered from the front panel to the front side V.

[0059] It is advantageous for a uniform design and for a wide distribution of the moisture that the structural unit 15 preferably extends over the entire width Q of the front side V of the domestic dishwasher 1.

[0060] The air outlet 14 is arranged at the upper end of the structural unit 15. The air outlet projects forward relative to the other outer wall portions of the structural unit toward the front side V, so that the blow opening 16 is directed further forward than the outer wall portion 18 of the front of the condensation region, in particular by a few centimetres. To this end, the interior air first extends at least almost vertically upward from the condensation region 19 and then transitions into the air outlet 14 here, which is horizontal, i.e. for example can be seen from Figure 2 and Figure 3 can be derived.

[0061] Here, the blow opening 16 preferably has a constant height over its width extension, so that the liquid distribution is also uniform. An interior air guiding device (not shown here) can ensure that the air outlet 14 supplies the more outer regions with air uniformly in the transverse direction Q.

[0062] The air outlet 14, by means of its (here preferably substantially horizontal) forwardly directed overhang, can rest on the upper edge of a base plate or base or skirting. In particular, the air outlet 14 with its lower edge of the forwardly directed overhang lies on the upper edge of the base plate. In Figure 2 , the base plate SB is indicated by a dotted line. The vertically extending condensation region 19 is arranged behind the base plate SB. Irrespective of the height of the base plate or base strip, the structural unit 15 can be positioned at the base plate or base strip in an installation-effective, simple manner, so that it is always ensured that the blow opening is arranged above the top edge of the base plate and thus the free blowing of air from the washing container is achieved. It is thus always avoided that the blowing-out path of the air from the blow opening 16 of the air outlet 14 is obscured by the base plate SB arranged in front of the structural unit 15.

[0063] One particularly advantageous refinement proposes that the blow opening 16 is formed as a wide and low slit between an upper lip 23 and a lower lip 24, and the lower lip 24 extends stably upward from the condensation region to the blow opening. Water that drips onto the lower lip can then reliably be guided back into the condensation region 19 and the collecting trough 17 without dripping into the outside space. During the standstill of the domestic dishwasher 1, the condensate collected in the trough-shaped collecting trough can evaporate again.

[0064] Here, in particular, the upper lip 23 can have a drip edge 25 at its downwardly directed side, which is arranged above the lower lip 24, i.e. slightly offset inward relative to the actual blow opening 16, for example by 4 to 8 mm. Water from the drip edge 25 then reliably hits the lower lip 24 and can flow back. To this end, the lower lip 24 can extend further out than the upper lip 23.

[0065] To achieve the removal of air, in particular moist air, from the rinsing container 2, an air channel 26, in particular several decimetres long, from the rinsing container 2 is provided upstream of the air outlet 14. The air channel 26, as mentioned above, begins in the rinsing container 2, in particular in a wall portion 13 of the rinsing container, within at least the upper 50% of the height H of the rinsing container 2. For example in a side wall portion 13, it is particularly advantageous for the rising water vapour to begin in the upper 50%, in particular 30%, of the height of the rinsing container 2.

[0066] Here, the air channel 26 up to the input end 20 coupled to the structural unit 15 has a variable length in a particularly advantageous manner. This is possible, for example, using a bellows. The provision of the structural unit 15 is thus variable in the depth direction T.

[0067] A fan wheel or a similar conveying mechanism is provided for conveying air from the rinsing container 2 to the air outlet 14. The fan wheel can be controlled in particular. Alternatively and particularly effectively, the conveying mechanism is adjusted via a humidity sensor device, which provides a measure of the current humidity of the rinsing object in the rinsing container.

[0068] In both cases, the conveying mechanism is only switched on from time to time in order to always remove moist air from the rinsing container 2 here, in turn maintaining the cleaning quality of the rinsing object over a longer period of time. Since the effective operating time is only very short, the energy requirement is low, as is the noise load caused by the at least one fan wheel or a similar conveying mechanism. The rinsing object can then also be stored in the rinsing container 2 for several days.

[0069] Overall, the risk of condensation at the air outlet 14 is significantly reduced by means of the present application. Here, the dew point of the air is also reduced by the condenser 19 connected upstream.
