Description

[0001] The present invention relates to a dishwasher with at least one drying unit comprising a sorbent, through which, in a drying phase, particularly moist air from a washing container in which dishes, glasses, cutlery and the like can be processed can be passed, wherein the washing container is provided with a movable front door for loading or unloading, according to the preamble of claim 1.

[0002] With these types of dishwashers, it is desirable that the dishes can be removed from the wash tub as completely dry as possible and without water spots. At the same time, however, energy consumption for drying should be low; furthermore, wetting of adjacent kitchen furniture or the worktop should be avoided.

[0003] For optimal drying results of dishes, glasses, cutlery, and similar items that can be washed in a dishwasher, it is advantageous to remove moist air from the dishwasher. It is therefore common practice to connect the dishwasher to an air outlet that carries moist air from the dishwasher to the outside. Such an air outlet is often located at the top of a front door that can be opened and closed automatically. Supplying air to this moving unit is therefore relatively complex and expensive. Furthermore, due to its high position within the appliance, there is a risk that cabinets or worktops located above the dishwasher, as well as parts of the dishwasher itself and its casing, could be damaged by the high volume of escaping moisture. Additionally, the kitchen floor in front of the dishwasher could become wet and therefore slippery.Furthermore, there is a significant draft in the immediate vicinity of such an air outlet, which is very uncomfortable, especially in small kitchens where users sit close to a dishwasher.

[0004] As an alternative to an air vent in the front door, the front door of a household dishwasher is often opened slightly during the drying phase of a wash cycle to aid drying. This allows moist air from the dishwasher's interior to escape into the surrounding environment and be replaced by drier ambient air. However, opening the door in this way—especially at the beginning of the drying cycle—causes heat to escape from the dishwasher, which is counterproductive from an energy perspective, as this heat is needed for drying. In particular, opening the door causes a significant amount of heat to be rapidly dissipated from the dishwasher into the surrounding environment, thus hindering the desired drying results.

[0005] It is also known to use a sorbent – ​​such as zeolite – which can bind moisture from the air as it passes through, thus enabling the return of dried air to the rinsing tank in a recirculating air process. However, this sorbent must be regenerated, which requires a significant amount of energy, in order to be able to absorb water again in the next rinsing cycle.

[0006] The dishwasher conforming to WO 2014 / 174784 A1 has, according to the Figures 1 - 5A wash tank with an air outlet allows air from the wash tank to be either directed into a recirculation duct leading to a dehumidification unit containing an adsorbent such as zeolite, via a downstream fan, and then back into the wash tank via an air inlet, or it can be directed out of the wash tank to the outside via an exhaust duct. Both the recirculation duct and the exhaust duct can be equipped with an air damper for opening and closing (see Figures 1 - 3However, as shown in Figures 4A and 4B, a common air damper can also be provided, by means of which the recirculation duct and the exhaust duct can be opened or closed alternately. During the drying phase of a dishwasher program, warm, moist air from the dishwasher is drawn from the dishwasher tub in a first phase exclusively through the recirculation duct by means of the fan and dehumidified exclusively by the dehumidification unit, while the exhaust duct is closed by means of its air damper or the common air damper. During a subsequent, second phase of the drying phase, the recirculation duct is closed by means of its air damper or the common air damper, while the exhaust duct is open, so that during this second phase the air from the dishwasher tub is drawn out to the outside exclusively via the exhaust duct by means of the fan.

[0007] The invention is based on the problem of achieving high cost and energy efficiency while minimizing the exposure of surrounding furniture, the kitchen floor and front parts of the dishwasher to water vapor, while still ensuring very good drying of the washed items.

[0008] The invention solves this problem by means of a dishwasher with the features of claim 1. Regarding advantageous embodiments and further developments of the invention, reference is made to claims 2 to 14.

[0009] The invention allows a dishwasher to, during the drying phase, redirect some of the air from the wash tub through a sorbent and back again after drying, while simultaneously expelling some air to the outside via at least one air outlet, with the front door remaining closed throughout the entire drying process. This achieves highly effective drying through a combination of different drying principles. Partial air expulsion eliminates the need to fully saturate the sorbent with water, thus significantly reducing the energy required for sorbent regeneration through desorption. Furthermore, keeping the front door closed eliminates the need for an automatic door opening mechanism, simplifying the design and resulting in considerable cost savings.Keeping the front door closed prevents rapid and significant heat loss, ensuring that sufficient heat energy remains in the wash tub for optimized drying results during the drying process. Furthermore, if the air outlet for expelling particularly moist air from the wash tub is located in the lower quarter of the appliance's height and, according to the invention, extends as a slotted outlet over at least two-thirds of the dishwasher's width, drafts are largely avoided. This wide extension allows for good distribution of the expelled air without any localized peaks.

[0010] Particularly advantageous in the first stage of the drying phase is drying via the sorbent, followed by drying via blown air in a subsequent stage. This allows for highly effective adsorption drying, e.g., using zeolite, to rapidly reduce the moisture content at the beginning of the drying process when the moisture content is particularly high. Simultaneously, this phase utilizes a recirculating air system, minimizing heat loss to the environment.

[0011] In particular, the first section with predominant adsorption drying can take up at least one third of the drying phase time, for example about 60% of the time.

[0012] Highly energy-efficient drying can be achieved if, during the first stage, the air is completely directed over the sorbent, and in a later stage, the air is completely directed through the air outlet. This minimizes the control effort and the loss of heat energy in the first stage.

[0013] During the drying phase, it is advantageous to direct air from the rinsing tank either to the air outlet or to the drying unit containing a sorbent, either selectively or simultaneously. This allows maximum flexibility in selecting the appropriate drying principle.

[0014] An advantageous feature is that, in addition to the air supply, a conveying device (such as a fan) that draws air from the rinsing tank and directs it onward, a valve control for further air supply is installed downstream. The conveying device can then continue operating in suction mode, and the hardware from the rinsing tank to the conveying device can be retained from a standard adsorption dryer.

[0015] Preferably, the air conveying device, in particular a fan, runs continuously throughout the two periods of the drying phase described above. The drying phase is, in particular, the final phase of a dishwashing program after the end of its last rinse phase, especially the final rinse phase, which involves the use of detergent liquid.

[0016] If the valve control includes a simple valve for opening or closing a blow-off line leading to the air outlet, this air outlet can also be activated in addition to zeolite drying.

[0017] If, for example, the valve control includes a three-way valve for setting different operating modes, it is possible to select either pure recirculated air drying via the sorbent, pure exhaust air drying through the air outlet, or a combination of both drying methods.

[0018] If the air outlet is located in the lower quarter of the appliance's height, rising water vapor from the outlet will first affect the dishwasher itself, allowing some of the water to condense there and preventing it from reaching furniture above. Furthermore, preferably because the air outlet is a slotted design extending over at least two-thirds of the dishwasher's width, a wide distribution of the escaping moisture and mixing with the drier outside air in the room is achieved. This disperses the humid air, preventing localized high levels of moisture from entering furniture. Drafts are also significantly reduced due to the wide air distribution.

[0019] Provided the air outlet has at least one air guide element for directing air towards the area in front of the dishwasher, and this element imparts a downward component to the outgoing air, the rising warm air can be directed to an area well in front of the kitchen cabinet fronts, thus protecting them from moisture exposure. Due to the downward airflow, the exiting air is initially guided away from the cabinet front in the area of ​​the cabinet panel, particularly in the area of ​​the dishwasher's front door, and only rises a few centimeters further away from the cabinet due to its own heat.

[0020] A very advantageous way to create an air guide element is to use an existing wall that already limits the air outlet at the top. This eliminates the need for additional components, simplifying the design and reducing material costs.

[0021] Provided that the air outlet is located on the front of the dishwasher facing the user and the air is blown forward with a component, it is ensured that the blown-out moist air cannot collect within a kitchen furniture unit, but instead escapes forward to the outside, allowing for good distribution of the contained moisture.

[0022] If, advantageously, the air guide element points downwards at least two degrees towards the front relative to the horizontal, the blown-out moist air can, for example, be directed under a door leaf that projects beyond the base, so that it remains free of moisture.

[0023] In particular, the air guide element can be angled downwards by at least four degrees towards the front, thus initially causing a significant downward movement of the exiting airflow before it rises due to its heat, well in front of the furniture. At the same time, however, the downward movement remains sufficiently small so that the exiting air does not leave a damp patch on the floor that could create a slip hazard. Therefore, the angular deviation from the horizontal remains at less than ten degrees, provided the air outlet is located in the upper area of ​​the base of a floor-standing dishwasher.

[0024] To externally limit the airflow, a wall that borders the air outlet downwards can incorporate a second air guide element, forming a discharge duct several centimeters long with the first air guide element, pointing towards the front. This allows for a defined, essentially laminar airflow. The second air guide element can be horizontal or slightly inclined to create a nozzle effect by narrowing the discharge duct. However, any incline of the second air guide element must be less than the slope of the upper air guide element to ensure the downward component is maintained.

[0025] A highly advantageous feature is a channel extending across the width of the air outlet and open at the top, through which partial airflows can be directed, flowing evenly throughout the entire channel. The leading edge of this channel can be angled against the essentially horizontal air outlet, which then draws in the widely distributed air from the channel and directs it forward.

[0026] The partial airflows in the aforementioned duct are particularly advantageous when separated from a common airflow coming from the flushing tank via an air distributor. This requires only one supply line, as the air is divided only upon entering the duct.

[0027] If the air outlet on a 60 cm wide dishwasher is at least 40 cm wide, a very wide and even distribution of moisture and outgoing air can be achieved. Ideally, the air outlet can extend almost the entire width of the appliance.

[0028] In particular, the air outlet is designed as a flat slot outlet with a height-to-width ratio between 1:20 and 1:200, most advantageously around 1:100. Despite its very low structural and visual height, a large discharge surface area can be achieved.

[0029] If the air outlet extends beyond a plinth panel that closes off the base at the front and projects at least the same distance forward, the moist air can escape sufficiently far forward to avoid excessive moisture exposure to the kitchen floor or the front of the dishwasher, especially the door. The expelled airflow can initially flow out at a slightly downward velocity and, due to its high temperature, develop an upward component as it travels a distance in front of the dishwasher.

[0030] Further advantages and features will become apparent from the exemplary embodiments of the subject matter of the invention shown in the drawing and described below.

[0031] The drawing shows: Fig. 1 a schematic perspective view from a front oblique angle of an embodiment of a dishwasher with a recessed base in the lower area, Fig. 2 a perspective view of a functional unit comprising an air guide from the wash tank to a conveying element, a drying unit including a sorbent, and a further outlet on the conveying element leading to a wide air outlet with diffuser located at the front, Fig. 3 a detail view, approximately corresponding to Detail III in Figure 2 , Fig. 4 a similar view as Figure 3 , however, a modified version with a three-way valve, Fig. 5 shows a view of two dew point curves and a temperature curve in the rinsing tank over time during the drying phase.

[0032] The in Figure 1The household appliance shown schematically here is a dishwasher 1, specifically a household dishwasher. Other household appliances with a drying function for the items being processed are also, in principle, suitable for a design according to the invention.

[0033] The household dishwasher 1 described below Figure 1The appliance, as a component of a partially open or closed external body G, has a wash container 2 for receiving items to be washed, such as dishes, pots, cutlery, glasses, cooking utensils, etc. The items can be held, for example, in dish racks 11 and / or a cutlery drawer 10 and exposed to a wash solution. The wash solution is understood to be fresh water or, in particular, water that has circulated during operation, with or without detergent and / or rinse aid and / or drying agent. In particular, the wash solution has passed through an ion exchanger for water softening. The wash solution may also contain, to a greater or lesser extent, soil from ongoing operation. The wash container 2 can have a generally rectangular base with a front face V facing the user in the operating position.This front panel V can form part of a kitchen front consisting of adjacent kitchen furniture, or, in the case of a standalone appliance, it can be without reference to other furniture.

[0034] The wash tank 2 can be closed, particularly on this front side V, by a front door or flap 3. This front door 3 is in Figure 1 The drawing shows the device in a partially open position, angled to the vertical. In its closed position, however, it stands upright and, according to the drawing, can be pivoted forward and downward around a lower horizontal axis in the direction of arrow 4, so that in the fully open position it lies at least almost horizontally.

[0035] On the vertical, user-facing outer and front side V of the dishwasher 1 in the closed position, the door 3 can be fitted with a decorative panel 6 to provide an optical and / or tactile enhancement and / or to adapt it to surrounding kitchen furniture.

[0036] The dishwasher is designed here as a freestanding unit, as a so-called semi-integrated unit, or as a fully integrated unit. In the latter case, the unit body G can essentially be sealed off from the outer walls of the wash tub 2. An external housing surrounding the tub may then be unnecessary. A base 12 for accommodating functional elements, such as a pump for circulating the wash water, and an air outlet 14 (described below) may be located in the lower section of the dishwasher.

[0037] In the embodiment shown in the drawing, the movable front door 3 has a control panel 8 extending in the transverse direction Q of the dishwasher in its upper region. This control panel may include an access opening 7, accessible from the front V, for manually opening and / or closing the front door 3. The dishwasher often has a transverse dimension Q of 45, 50, or 60 centimeters. Its depth T, from the front V to the rear, is also often approximately 60 centimeters. These values ​​are not mandatory. Furthermore, the dishwasher 1 does not necessarily have to stand directly on a floor B, but can also be installed at approximately eye level within a kitchen unit. In this case, the previously mentioned issue of drafts through an air outlet 14 must be given particular attention.

[0038] The wash tank 2 is bounded all around by a total of three fixed vertical walls 13 and two horizontal walls 13 when the front door or flap 3 is closed. One of these horizontal walls forms the top and the other the bottom of the wash tank 2. Adjoining the front V facing the user in the transverse direction Q are a left vertical side wall 13 and a right vertical side wall 13.

[0039] The wall 13, which forms the base of the wash tank 2 and essentially defines its lower boundary, lies approximately horizontally above the plinth 12, i.e., parallel to an outer base B on which the dishwasher 1 can stand. As mentioned, a higher installation, for example at the height of a worktop, is also possible, particularly within a cabinet. In this installed position, the lower edge of the dishwasher 1 is approximately 70 to 110 centimeters above the floor.

[0040] The dishwasher 1 is equipped with at least one air outlet 14 for blowing out air, especially moist air, from the wash chamber 2. This air outlet 14 can blow air, especially moist air, extracted from the wash chamber into the free air space on the front V of the dishwasher 1 facing the user, so that the moist air is not introduced into a kitchen unit and could cause moisture damage there.

[0041] The air outlet 14 is part of a discharge assembly 15, which together comprise approximately Figure 2 The exhaust assembly 15, comprising at least one air outlet 14, extends over at least half the width Q of the dishwasher 1, and in particular over more. This allows for a particularly even distribution of the exiting air, thus minimizing drafts.

[0042] The exhaust assembly 15 can be made entirely of plastic. Furthermore, the air outlet 14 can be divided into several parallel slots. These slots do not all need to be of the same length. The important thing is that an overall wide air outlet 14 is created, enabling a high airflow to achieve a broad distribution of the moisture contained in the air.

[0043] The air outlet 14 is located in the lower quarter of the appliance height and extends as a one- or multi-part slot outlet over at least two-thirds of the width Q of the dishwasher 1. In particular, in a household dishwasher with a 60 cm appliance width, the air outlet 14 is at least 40 centimeters wide. It can be positioned as shown in the Figures 2 and 3 which is clearly visible, also extends over almost the entire width Q of the dishwasher 1.

[0044] The dishwasher 1 is further equipped with at least one drying unit 16 comprising a sorbent, through which, during a drying phase, particularly moist air from a wash tank 2, in which dishes, glasses, cutlery and the like can be processed, can be passed. The air thus guided and dried can then be returned to the wash tank 2 via an exhaust nozzle 17 in recirculation mode.

[0045] The supply of air from the rinsing tank 2 is ensured via an inlet nozzle 18 located in the upper area of ​​the rinsing tank into an air supply 19, which in particular forms a closed channel and leads to a conveying device 20, in particular a fan wheel, in order to draw in the air via the air supply 19 and convey it onwards.

[0046] Two options are provided for the onward routing: firstly via the first outlet 21 into the drying unit 16, secondly via the second outlet 22 to the wide air outlet 14.

[0047] This makes it possible for the dishwasher 1, during a drying phase, particularly during a dishwasher program, to direct some of the air from the wash tub 2 via the drying unit 16 and the sorbent located therein, and to direct some of it to at least one air outlet 14 to the outside. The front door 3 remains closed throughout the entire drying phase, so that heat loss from the wash tub is considerably slower and more controlled than if the door were open.

[0048] In the Figure 5In the illustrated and exemplary drying phase, drying via the sorbent predominates in a first section 23 of the drying phase, while drying via the blowing of air through the air outlet 14 predominates in a subsequent section 24. The air conveying device 20, in particular a fan, preferably runs continuously throughout both time periods 23 and 24 of the drying phase. In this exemplary embodiment, the drying phase is, in particular, the program-concluding phase of a dishwashing program to be carried out, after the end of its last partial wash phase containing detergent, especially the rinse phase.

[0049] In Figure 5 It is evident that the first section 23 occupies at least half of the drying phase, for example, the time from minute approximately 160 to minute 212, whereas the second section 24 runs from minute 212 to minute approximately 250.

[0050] In particular, it may be the case that in the respective section one or the other drying method not only predominates, but that during the first section 23 the air is completely directed over the sorbent and in a later section 24 the air is completely directed through the air outlet 14. Especially in the initial phase of drying, complete recirculation of air via the drying unit 16 is then possible, so that practically no heat energy, which is essential for drying, escapes from the rinse tank 2 to the outside.

[0051] Nevertheless, it is possible that during a drying phase air from the rinsing container can be directed either optionally or together to the air outlet 14 and / or to the drying unit 16 containing a sorbent.

[0052] To enable different operating modes, a valve control 25 for further air supply is arranged downstream of the conveying element 20.

[0053] For example, a shared use of drying unit 16 and air outlet 14 is possible if the supply to drying unit 16 is open and a simple open-close valve is used as a valve control 25 in the second outlet 22 to air outlet 14, as shown in Figure 3 is shown.

[0054] As an alternative in Figure 4 As shown, the valve control 25 can, for example, include a three-way valve for setting different operating modes. This allows not only simultaneous operation of both outlets 21 and 22, but also the individual and sequential control of each outlet 21 or 22.

[0055] This also makes it possible to strictly separate the air supply to the drying unit 16 on the one hand and to the air outlet 14 on the other, without both paths 21, 22 being supplied in parallel.

[0056] The air outlet 14 is located on the front V of the dishwasher facing the user and, to ensure draft-free and, in particular, moisture-damaging air discharge into the area in front of the front V of the dishwasher 1, comprises at least one air guide element 26, here the upper surface of the actual diffuser 27, which imparts a downward component to the outgoing air. The air exiting forward is therefore not completely horizontal, but slightly downwards.

[0057] The air guide element 26 points downwards towards the front V by at least two degrees. The slope can also be greater and point downwards by at least four degrees.

[0058] At the air outlet 14, a downwardly limiting wall is provided opposite the air guide element 26, which forms a second air guide element and in this way forms with the first air guide element 26 a nozzle-like tapered discharge channel several centimeters (typically about 5 to 8 centimeters) in length pointing towards the front V.

[0059] This allows the air outlet with its forward-extending V-shaped discharge duct to extend over a plinth panel 5 that is significantly recessed from a front door 3 and forms a base 12 at the front, and to project at least the same distance towards the front V. This prevents the plinth panel 5 itself from becoming exposed to moisture. However, the downward component of the discharged airflow, introduced via the air guide element 26, also directs it under the front door 3, which projects further towards the front V (e.g., 5 to 10 centimeters), without, for example, moistening the front decorative element 6. Instead, the airflow is conveyed a few centimeters further forward V before it can rise due to its higher temperature compared to the surrounding kitchen air. At this point, it is sufficiently far away from the cabinet fronts. Simultaneously, the slight slope of the air guide element 26 also prevents the floor B from becoming moistened.The wide extension of the air outlet 14 also prevents disruptive drafts.

[0060] The conveying unit 20 can also be controlled intermittently, even over a period of several days. Alternatively, and particularly effectively, the conveying unit is controlled by a moisture sensor that provides a measure of the current moisture content of the items being washed in the washing tank.

[0061] Such a dishwasher 1 can also be equipped with a so-called storage function, which allows the dishes to remain in the wash chamber 2 after processing without becoming damp again. This retention can last for several days without any deterioration in the dryness of the dishes. The dishwasher 1 then also serves as a storage and drying cabinet from which the dishes can be removed fresh and dry.

[0062] In both cases, the conveying unit is only switched on intermittently to repeatedly remove moist air from the wash tank 2, thus maintaining the cleaning quality of the items even over extended periods. Due to the short effective operating times, energy consumption is low – as is the noise level from the at least one fan or similar conveying unit.

[0063] To introduce moist air from the rinsing tank 2 into the air outlet 14, at least one connection is provided on the rear side of the air outlet 14. The air introduced through this connection can first be directed to an air distributor that projects into the cross-section of the tubular connection and divides the airflow approximately in the middle.

[0064] The air distributor transitions into a curved air guide element that projects into a duct located behind (i.e., facing away from the front V) the air outlet 14 in the transverse direction Q. The duct is considerably higher than the air outlet 14 and may have condensate drains on its underside.

[0065] Thus, the partial flows in the channel are diametrically opposed to each other and run from the air distributor, which is ideally located centrally with respect to the transverse direction Q, to almost both outer walls of the dishwasher 1. The partial flows have a sufficiently high velocity to maintain an approximately uniform density on their opposing paths through the channel before the air, with one component moving upwards and forwards, can exit the channel into the actual diffuser 27.

[0066] Ideally, the channel should have an extension in the lateral direction Q of the same size as the diffuser 27, in particular at least 40 centimeters.

[0067] In particular, the air outlet 14 – which can be one or more parts – is used for this purpose, according to Figure 2 Designed as a flat slot outlet, its height-to-width ratio can be between 1:20 and 1:200, preferably around 1:100 (especially in the case of a household dishwasher with a 60 cm appliance width). In this case, for a 40 cm wide air outlet 4, its height in the vertical direction H is less than approximately 2 cm. This ensures that, on the one hand, it occupies little installation space in the vertical direction H, and on the other hand, the overall extent of the air outlet 14 is large enough to expel a high volume and thus keep drafts to a minimum.
