Description

[0001] The invention relates to a drying device, in particular a recirculating air drying device, for a dishwasher, comprising an intake duct providing an air intake opening, an outlet duct providing an air outlet opening, and a blower to which the intake duct and the outlet duct are fluidically connected on the air intake side, wherein the blower has a housing and a blower wheel rotatably arranged therein.

[0002] Dishwashers in general, and those with a drying device of the type mentioned above in particular, are well known from the prior art, which is why a separate printed reference is not required at this point.

[0003] A dishwasher, particularly a typical household dishwasher, has a wash chamber that serves to hold the items to be cleaned. In the case of a household dishwasher, these items are primarily dishes and cutlery.

[0004] In normal use, a dishwasher undergoes drying after the washing process. Various drying methods are known in the art, including hot air drying, in which the items to be dried are exposed to preheated drying air. The air contained within the dishwasher's wash chamber can be used as the drying air, in which case hot air drying occurs in recirculation mode. Alternatively and / or in combination with this, fresh air drawn from the atmosphere surrounding the dishwasher can also be used for drying.

[0005] Regardless of whether hot air drying is carried out using recirculated air and / or fresh air, a drying unit is used for airflow and heating. This unit provides the necessary air ducts and includes a fan and a heating element. Furthermore, temperature sensors may be incorporated to regulate the heating output and monitor the system.

[0006] A drying device of this type for hot air drying has an intake duct on one side and an exhaust duct on the other. The intake duct provides an air intake opening, while the exhaust duct has an air outlet opening. In normal use, drying air is supplied to the intake duct through the air intake opening and then conveyed through the exhaust duct to the air outlet opening. The drying air exiting the drying device through the air outlet opening then enters a dishwashing container of a dishwasher connected to the drying device.

[0007] To convey the drying air, the drying device has a blower. The intake duct and the outlet duct are fluidically connected to this blower. The blower has a housing and a fan wheel, which is rotatably mounted within the housing. Under normal operating conditions, the fan wheel is driven by a suitable electric drive unit. The blower is preferably a radial blower.

[0008] To heat the drying air, the drying unit also has a heating element. This is typically located in the outlet duct, meaning that the air drawn in by the blower passes through the heating element before leaving the drying unit via the air outlet opening.

[0009] Under normal operating conditions, water from the wash tub can splash into the drying unit through the air outlet and / or air intake openings of a dishwasher. Furthermore, steam generated in the wash tub during a wash cycle can enter the drying unit through the openings on the drying unit side, where it condenses inside the channels, resulting in condensation.

[0010] To prevent the drying unit's blower from failing, it is known in the prior art to provide a corresponding drain opening through which any condensate accumulating in the blower housing can drain away. This drain opening interacts with a drip tray provided by the dishwasher, in which the condensate collects, subsequently allowing it to evaporate. The drip tray on the dishwasher side typically serves to collect any liquids that may leak from the dishwasher in the event of a malfunction. Therefore, the drip tray is also equipped with a switch that is activated when a certain fill level is reached, resulting in the immediate interruption of any wash program being performed by the dishwasher.

[0011] Although the aforementioned design has proven effective in everyday practical use, there is room for improvement. Condensation escaping from the drying unit can unintentionally activate the safety switch in the drip tray. In this case, a leak or other malfunction of the dishwasher is mistakenly assumed, leading to an immediate shutdown of the dishwasher, even though only condensate generated in the drying unit has been properly drained. Such a misinterpretation must be avoided, which is why the invention underlying this design addresses this issue. Task The aim is to further develop a drying device of the type mentioned above in such a way as to enable safe operation.

[0012] To SolutionThe invention proposes a drying device of the type mentioned above to solve this problem, characterized in that the housing has an overflow opening for condensate accumulating in the housing and that a collection and evaporation tray is arranged below the housing, which is in fluid-technical contact with the overflow opening on the housing side.

[0013] According to the invention, the drying device itself has a collection and evaporation tray into which condensate accumulating in the drying device can be directed as needed. In contrast to the prior art, a collection tray integrated with the device is not used; instead, a separate collection and evaporation tray is provided. This effectively prevents a safety switch interacting with the device's collection tray from being activated when condensate escapes from the drying device. This is because, unlike in the prior art, the condensate is not transferred to the device's collection tray, but rather to the dedicated collection and evaporation tray provided by the drying device itself.

[0014] The blower of the drying device has, in a manner known per se, a housing and a fan wheel rotatably mounted within it. The housing is equipped with an overflow opening. This overflow opening serves to drain any condensate that accumulates in the housing. This overflow opening is fluidically connected to the collection and evaporation tray, so that, in the event of condensate formation, it can be drained via the overflow opening and transferred into the collection and evaporation tray.

[0015] According to the invention, the collection and evaporation tray is arranged below the housing, so that condensate discharged through the overflow opening can flow downwards by gravity and collect in the tray. This provides a remarkably simple yet effective design that, in the event of condensation, ensures that any condensate accumulating in the housing of the drying device's blower is transferred to the designated collection and evaporation tray for evaporation. Furthermore, as will be described in more detail below, the blower housing itself can be designed to hold a certain amount of condensate before it flows out through the designated overflow opening.

[0016] According to a further feature of the invention, the collection and evaporation tray has a locking device for detachable arrangement on a counterpart, preferably on a machine base of a dishwasher.

[0017] The collection and evaporation tray is equipped with a locking mechanism. This locking mechanism allows the collection and evaporation tray to be detachably attached to a counterpart. The advantages of this design are, firstly, that assembly can be carried out without tools, and secondly, that disassembly is also possible, since the locking mechanism according to the invention allows for a detachable arrangement, so that, if necessary, the collection and evaporation tray can be separated from the counterpart without damage. The machine base of a dishwasher is particularly suitable as the counterpart to which the collection and evaporation tray is attached when needed.It is advantageous that the base of a dishwasher is typically identical across a number of dishwashers with differing details, so that the collection and evaporation tray equipped with the locking device provided according to the invention can be used equally well for a large number of dishwashers with differing details. This allows the collection and evaporation tray according to the invention to be used in a structurally identical manner for different types of dishwashers. A wide range of applications is thus created.

[0018] According to a further feature of the invention, the collection and evaporation tray has a bearing arrangement for supporting the blower. According to this particularly preferred embodiment of the invention, a synergistic effect is achieved because the collection and evaporation tray not only serves, as previously described, to collect any condensate that may form in the drying device, but also to serve as a bearing for the blower of the drying device. The collection and evaporation tray according to the invention thus fulfills two functions. In the The result is a simplified design that also takes up little space in the overall structure.

[0019] According to a further feature of the invention, the bearing arrangement is designed to support the blower in a floating manner in the vertical direction of the drying device. "Floating" in the context of the invention means that the bearing arrangement provided by the collection and evaporation tray provides a floating bearing in the vertical direction, which allows relative movement between the blower and the collection and evaporation tray in that direction.

[0020] The drying unit consists of three basic components: first, air ducts for unheated drying air; second, air ducts for heated drying air; and third, the blower. Both the air ducts for unheated and heated drying air are fluidically connected to the blower. During normal operation, thermal expansion can occur, which precludes a fixed connection of all three components of the drying unit to the dishwasher. Otherwise, stress-related damage could occur during normal operation. The design according to the invention addresses this issue by allowing the blower to float vertically, thus absorbing thermal expansion.The support provided by the bearing arrangement according to the invention for the blower is designed to float only in the vertical direction. Transversely, the bearing arrangement acts as a fixed bearing, preventing the blower from unintentionally shifting relative to the other components of the drying system. The air ducts of the drying system are, for example, arranged on the side wall of a dishwasher's wash tub. The blower, however, is supported by the bearing arrangement of the collection and evaporation tray according to the invention, and is also supported in the vertical direction, allowing for tolerance compensation in this direction, particularly to compensate for thermally induced expansion. Manufacturing tolerances can also be advantageously compensated for in this way.

[0021] According to a further feature of the invention, the bearing assembly is provided to have a bearing bore. This bearing bore constitutes a first bearing component.

[0022] According to a further feature of the invention, the blower housing has a bearing journal that interacts with the bearing bore. This provides a second bearing component. In the fully assembled state, the housing-side bearing journal engages in the corresponding bearing bore of the bearing assembly. This results in a vertically floating bearing arrangement, as previously described. However, a positional fix occurs transversely to this, i.e., transversely to the longitudinal extent of the bearing journal. Consequently, tolerance compensation is permitted in the longitudinal direction of the bearing journal, but not transversely.

[0023] According to a further feature of the invention, the bearing bore is provided by a damping element. Such a damping element can, for example, be made of a soft, elastic plastic material, such as an elastomer. This advantageously prevents contact noise, particularly during movement. Furthermore, the damping element provides spring-like support for the housing, which contributes to the durability of the entire construction.

[0024] According to a further feature of the invention, the collection and evaporation tray has a receptacle for arranging the damping element. In the fully assembled state, the damping element is secured in position relative to the collection and evaporation tray within this receptacle. The damping element, in turn, provides the bearing bore through which the bearing journal of the blower housing engages. As a result, the blower housing is thus secured relative to the collection and evaporation tray by means of the damping element. This provides an overall simple and compact design.

[0025] According to a further feature of the invention, the damping element has a locking contour on the tray side. This ensures simplified handling, particularly in the first assembly case, since the damping element only needs to be inserted into the designated receptacle of the collection and evaporation tray, and the locking contour provided by the damping element then ensures that the damping element is securely positioned on the collection and evaporation tray.

[0026] Overall, the aforementioned design achieves a minimized size, requiring only a small installation space. This is particularly advantageous given the already limited installation space available for dishwashers.

[0027] According to a further feature of the invention, the bearing journal has a cross-section that deviates from a circular shape on the bearing bore side. In particular, the bearing journal can have a star-shaped or cross-shaped cross-section in the area where it overlaps the bearing bore. This advantageously creates an overflow in the insertion area between the bearing journal and the bearing bore, through which condensate collected by the collection and evaporation tray can pass. This advantageously ensures that, in the event of a quantity of condensate exceeding the capacity of the collection and evaporation tray, uncontrolled condensate outflow from the tray is prevented. Instead, the aforementioned design creates a controlled overflow that ensures the controlled drainage of excess condensate.This excess condensate can then be transferred to a collection tray already provided on the machine. Thus, the geometric design of the bearing journal provides a simple overflow mechanism that, in the event of an unexpectedly large amount of condensate, allows it to flow into the machine's collection tray, potentially activating a safety switch connected to the tray. The collection volume of the inventive collection and evaporation tray is dimensioned such that, under normal operating conditions, condensate typically does not overflow into the machine's collection tray. However, in the event of a defect or malfunction, it is ensured that a safety device already provided on the dishwasher will activate if an exceptionally large amount of condensate accumulates.

[0028] According to a further feature of the invention, the damper element provides an inclined surface on the housing side. This inclined surface ensures that the overflow of the type described above only engages when the fill level within the collection and evaporation tray has reached a height where there is a risk of overflowing beyond the edge of the collection and evaporation tray.

[0029] According to a further feature of the invention, the overflow opening is arranged in the vertical direction of the housing, forming a housing-side condensate reservoir above a lowest housing point provided by the housing.

[0030] This design takes advantage of the fact that the blower housing can absorb a certain amount of condensate without risking blower failure. Failure is only a concern if such a large amount of condensate accumulates in the blower housing that the impeller, which is rotatably mounted within the housing, can no longer rotate freely. Therefore, it is possible to use the gap provided between the blower housing and the impeller for condensate absorption without any risk of failure.

[0031] The blower is preferably a radial blower. By design, this type of blower has a worm gear housing, meaning a housing with a radius that increases towards the outlet, and thus a gap between the impeller and the housing that also increases towards the outlet. This space, which is already provided between the impeller and the housing, can be used for the temporary storage of condensate without unduly impairing the blower's functionality.

[0032] For this reason, it is also provided according to the invention that the overflow opening provided for the removal of condensate is arranged in the vertical direction of the housing, forming a housing-side condensate reservoir above a lowest housing point provided by the housing.

[0033] The inventive design thus provides three retention stages for the condensate that accumulates. Firstly, a reservoir on the blower side is provided, which can hold an initial quantity of condensate. If more condensate accumulates than can be held by the housing's own reservoir, excess condensate flows out through the designated overflow opening. This condensate, discharged via the overflow opening, enters the collection and evaporation tray on the drying unit side. This tray provides a certain amount of storage volume. If more condensate accumulates, it flows out via the tray's overflow into the machine-side collection tray. This tray is equipped, in a manner known per se, with a safety switch that is activated if the fill level within the collection tray becomes too high.

[0034] According to a further feature of the invention, the overflow opening is formed at the end of a nozzle on the housing wall. This enables targeted condensate drainage. Furthermore, it allows for pressure equalization in the area of ​​the overflow opening, which improves the flow of drying air within the blower housing.

[0035] The invention further proposes a dishwasher that has a drying device of the type according to the invention. Such a dishwasher has the advantages already described above.

[0036] According to a further feature of the invention, the dishwasher has a machine-side drip tray which is arranged vertically below the collection and evaporation tray of the drying unit. This ensures, as described above, that in the event of an overflow of the collection and evaporation tray, any condensate flowing from it can enter the machine-side drip tray provided for this purpose. This is particularly advantageous for safety reasons, as the drip tray is equipped with a safety switch.

[0037] Further features and advantages of the invention will become apparent from the following description with reference to the figures. These show Fig. 1 shows a schematic perspective view of a dishwasher according to the invention; Fig. 2 shows a schematic side view of the dishwasher according to the invention. Fig. 1Fig. 3 shows a further schematic side view of a dishwasher according to the invention; Fig. 4 shows a schematic perspective view partially of the blower of a drying device according to the invention; Fig. 5 shows a schematic partial sectional view of the blower according to Fig. 4 ; Fig. 6 in a schematic exploded view shows a partial view of the base of a dishwasher according to the invention from below and Fig. 7 in a schematic perspective view shows a partial view of the bearing of the blower of the drying device according to the invention.

[0038] Fig. 1 Figure 1 shows a dishwasher according to the invention in a schematic perspective view.

[0039] The dishwasher 1 has, in a manner known per se, a washing container 2 which provides a washing chamber 3 and which, in the intended use, serves to hold items to be cleaned.

[0040] For the purpose of hot air drying of items to be washed in the washing container 2, the dishwasher 1 has a drying device 9.

[0041] As can be seen from a synthesis, in particular the Figure 1 and 2 The drying device 9 has an intake duct 10 on one side and an outlet duct 12 on the other for guiding drying air. Furthermore, the drying device 9 has a blower 14, to which the intake duct 10 and the outlet duct 12 are fluidically connected on the air intake side.

[0042] The blower 14 of the drying device 9 is arranged in the base area 18 of the dishwasher 1, i.e. in the vertical direction 8 below the wash tub 2. The two channels, i.e. the intake channel 10 and the outlet channel 12, are arranged on the outside of the wash tub 2 on a side wall 4 of the wash tub 2.

[0043] As can be seen in particular from the presentation according Fig. 1 The washing container 2 has two side walls 4, a ceiling part 5, a bottom part 6 and a rear wall 16. Opposite the rear wall 16, a loading opening is provided through which, in the intended use, the washing container 2 can be loaded with items to be washed.

[0044] As can further be seen from a summary of the Fig. 1 and 2 As a result, the intake duct 10 of the drying unit 9 provides an air intake opening 11. Accordingly, the outlet duct 12 has an air outlet opening 13. Both openings, i.e., the air intake opening 11 and the air outlet opening 13, each open into the washing chamber 3. Therefore, in the intended use, an airflow can occur, as described in Fig. 2The arrows 17 shown indicate the direction of flow.

[0045] In accordance with the representation according to Fig. 2 In the intended use of the drying unit 9, recirculation of air takes place. The blower 14 draws drying air from the washing chamber 3 via the air intake opening 11. This drying air passes through the intake duct 10 and the blower 14 to the outlet duct 12. A tubular heating element assembly of a heating device 15 (not shown in detail in the figures) is integrated into the outlet duct. This assembly heats the drying air passing through the outlet duct 12. The heated drying air leaves the drying unit 9 via the outlet opening 13 provided by the outlet duct 12, thus returning it to the washing chamber 3.

[0046] As the Fig. 1 and 2Furthermore, it can be seen that both the intake port 10 and the exhaust port 12 each have an overlift 19 and 21 respectively, each with a partially circular channel deflection 20 and 22 respectively.

[0047] The overflows 19 and 21 each serve to prevent any water entering a channel 10 or 12 through the respective openings 11 and 13 from flowing to the blower 14. This is because any water introduced into the channels 10 or 12 through the openings 11 and 13 cannot rise against gravity thanks to the respective overflows 19 and 21, i.e., thanks to the respective channel deflections 20 and 22, but is instead guided back into the flushing chamber 3 through the respective openings 11 and 13 under the influence of gravity.

[0048] As in particular a synthesis of Fig. 2 and 3As can be seen, the blower 14 has a housing 23 and a blower wheel 24 rotatably arranged therein. Preferably, the blower 14 is a radial blower, as is also shown in the figures.

[0049] According to the invention, the drying device 9 has a collection and evaporation tray 25, as shown in the schematic representation. Fig. 3 This collection and evaporation tray 25 is arranged in the vertical direction 8 below the housing 23 of the blower 14.

[0050] As in particular the presentation according Fig. 5 As can be seen, the housing 23 has an overflow opening 26 for condensate accumulating in the housing 23. In the illustrated embodiment, this overflow opening 26 is provided by a nozzle 27.

[0051] The collection and evaporation tray 25 is fluidically connected to the housing-side overflow opening 26, as can be seen in particular from a review of the Figures 3 to 5 This results in condensate accumulating in the housing 23 during intended use, which can therefore be drained from the housing 23 through the overflow opening 26 provided for this purpose, flowing downwards in the vertical direction 8 following gravity and being collected by the collection and evaporation tray 25.

[0052] For the purpose of securing its position, the collection and evaporation tray 25 has a locking device 34. This is particularly evident from a review of the Fig. 5 and 6This locking device 34 serves to detachably arrange the collection and evaporation tray 25 on a counterpart, which in the illustrated embodiment is a machine base provided by the dishwasher 1. The locking device 34 has two rail-like retaining elements which, in the fully assembled state, engage in correspondingly designed receptacles in the machine base 33. Fig. 5 and 6 This reveals this.

[0053] The collection and evaporation tray 25 also has a bearing device 28, which serves to support the blower 14. This connection is shown in particular by the Fig. 3 , 4 , and 5 again.

[0054] The bearing assembly 28 is designed to support the blower 14 in a floating manner in the vertical direction 8 of the drying unit. "Floating" in this context means that the blower 14 is freely movable relative to the collection and evaporation tray 25 in the vertical direction 8, and the bearing assembly 28 thus provides a floating bearing with respect to the vertical direction 8. Transversely to the vertical direction 8, the bearing assembly 28 provides a fixed bearing, so that relative movement of the blower 14 with respect to the collection and evaporation tray 25 in this direction is not possible.

[0055] This floating mounting of the blower 14 has the advantage that, in particular, temperature-related tolerance compensation in the vertical direction 8 is permitted. This is necessary because the channels 10 and 12 of the drying unit 9 are arranged on the associated side wall 4 of the rinsing tank 2, so that unwanted stresses would occur within the drying unit 9 due to temperature-related expansion if the blower 14 were also held in a fixed position in the vertical direction 8. The bearing assembly 28 provided with the collection and evaporation tray 25 remedies this and enables the design according to the invention to compensate for temperature-related expansions, in particular of the air guide channels 10 and 12 of the drying unit 9. Unnecessary stresses in the individual components are thus avoided, which contributes to the longevity of the entire design.

[0056] With regard to the bearing assembly 28, it is further provided that it provides a bearing bore 29. In the final assembly state, a bearing journal 30 provided by the housing 23, which is received by the bearing bore 29, such as the Fig. 4 and 5 The bearing bore 29 is provided by a damping element 31, which is made of an elastomeric material. The damping element 31 itself is received by a receptacle 32 of the collection and evaporation tray 25, which receptacle is, for example, a through bore, as shown in the Fig. 6 and 7As can be seen in the following. For the purpose of ensuring the positional stability of the damping element 31 on the collection and evaporation tray 25, the damping element 31 has a locking contour 35 on the tray side. This interacts with an undercut edge of the receptacle 32 provided by the collection and evaporation tray 25, as can be seen in particular. Fig. 7 can be seen from this. In the The result of this design is the housing-side bearing pin 30, positioned with the damping element 31 interposed on the collection and evaporation tray 25. The collection and evaporation tray 25 thus combines two functions in one component. Firstly, in the event of condensation, it serves to collect condensate escaping from the housing 23 of the blower 14. Secondly, it provides the bearing arrangement 28, which is designed to support the blower 14 in a floating manner in the vertical direction 8.

[0057] As can be seen in particular from the presentation according Fig. 7 As a result, the bearing journal 30 has a cross-section on the bearing bore side that deviates from a circular shape. In the In the illustrated embodiment, the cross-section of the bearing journal 30 is cruciform. This results in guide channels in the contact area between the bearing journal 30 and the damper element 31, which serve as overflow channels 36. As can be seen in particular from Fig. 7 This results in the condensate level within the collection and evaporation tray 25 becoming too high being allowed to flow out via the contact area between the bearing journal 30 and the damping element 31, namely through the overflow 36 formed by the guide channels. The condensate discharged through the overflow 36 enters a collection tray 38 provided on the machine side, which is arranged in the vertical direction 8 below the collection and evaporation tray 25, as shown in particular in the schematic diagram according to Fig. 3This can be seen.

[0058] In order to ensure that excess condensate can only be fed into the overflow 36 once the collection and evaporation tray 25 has reached its capacity, the damping element 31 has an inclined surface 37 that slopes radially outwards from the bearing bore 29 provided by the damping element 31, as shown in the illustrations. Fig. 5 and 6 can be seen from this.

[0059] As a result of the aforementioned design, the collection and evaporation tray 25 according to the invention provides a component that combines the functions of "fixing the blower 14" and "collecting condensate." The collection and evaporation tray 25 is only installed on the machine base 33 of the dishwasher 1 if the dishwasher is also equipped with a drying device 9 according to the invention. Otherwise, the collection and evaporation tray 25 is not required, so it can be omitted and the installation space provided by the dishwasher 1 can be used for other components. Reference sign
