Definitions

  • the invention relates to a functional module for a water-bearing household appliance, in particular a washing machine or a dishwasher, and such a water-bearing household appliance with such a functional module.
  • Known water-bearing household appliances or washing machines are devices that are assembled from nothing but individual components or assemblies. These components or assemblies are contained in a housing of the washing machine and are attached to a frame in this housing or to brackets. Above all, important functional units such as the drive motor for the drum, pump, detergent dosing, filters, valves or the like. are distributed differently and must be mounted individually. This makes the construction, assembly and, above all, repairs very complicated and time-consuming.
  • the invention is based on the object of creating a functional module as mentioned at the outset and a water-conducting household appliance provided with it, with which problems of the prior art can be solved and in particular it is possible to improve the design, assembly and repair of the water-conducting household appliance, in particular to achieve a new division.
  • the functional module is designed as an independently manageable structural unit.
  • This structural unit is movable and can be movable in particular in a water-bearing household appliance, that is to say it can advantageously be movably mounted therein.
  • the function module can not only be used as a possibly pre-assembled unit are installed in such a water-bearing household appliance, but is then also within the water-bearing household appliance and movable relative to it, in particular the functional module can be at least partially pulled out of the household appliance.
  • the function module has a pump that fulfills a task in the water-bearing household appliance, in particular works as a circulating pump or is provided as a circulating pump.
  • the functional module also has at least one valve, advantageously a plurality of valves. This is explained in more detail below.
  • the function module has at least one filter, possibly also several, for example a coarse filter and at least one fine filter.
  • the functional module advantageously also has a dosing device for detergents or cleaning agents.
  • This can contain alternative or other additives for washing or cleaning processes that are commonly used.
  • a dosing device can be designed on the one hand for a one-time manual dosing of detergent or cleaning agent or additives per washing process, similar to what is currently known from drawer-like dosing devices of washing machines.
  • the dosing device can also have a larger supply of detergent or cleaning agent or additives, which are sufficient for several washing processes and thus do not have to be filled in individually for each washing process. The appropriate dosage for each washing process is then made by the water-bearing household appliance itself, but this is known per se.
  • the functional module also has a number of fluid lines between the aforementioned parts or functional units.
  • fluid lines run to and from the filter, the valve, the pump and any metering devices that may be provided.
  • fluid lines can run between the components mentioned, ie within the functional module.
  • they can also form a connection of the functional module to the outside or to the other components of the water-bearing household appliance, in particular to a drum of a washing machine or in a washing compartment of a dishwasher and to a water inlet or fresh water connection and a water outlet.
  • a water-carrying household appliance can be assembled more quickly, since such a function module can be obtained prefabricated from a supplier and then, so to speak, only has to be pushed into the household appliance.
  • such a functional module can also be at least partially moved or pulled out of the household appliance during repairs or maintenance, in a similar way to the simplified way in which it can be pushed in for assembly of the household appliance. This can also be used to refill or replace a previously mentioned dosing device that may be present.
  • these processes are also considerably simplified. For example, to repair or even just to diagnose the pump of a washing machine, a cover of the washing machine must first be loosened and lifted off, possibly also a rear wall, since a pump in a washing machine is usually arranged below the drum and is therefore difficult to access.
  • the functional module simply has to be pulled out of the washing machine in a forward direction, the washing machine does not even have to be removed from its possibly built-in and precisely aligned position. Repairs and maintenance are then considerably easier. This also applies in a similar way to a dishwasher.
  • the great advantage of the invention also lies in the fact that structural units such as a pump and valves, which are otherwise usually connected to fluid lines within the water-bearing household appliance in a complex and sealed manner, are so flexible that they can easily be moved out when the functional module is moved. This is because these components are usually permanently installed in the household appliance, so that the obstacle first had to be overcome mentally.
  • the fluid lines are at least partially variable in length and/or are bendable. In this way, they can enable the functional module to be moved without removing one of their connections.
  • the fluid lines are designed as flexible and/or elastic and/or telescoping hoses.
  • either very elastic plastic or rubber hoses, which can therefore be stretched, can be used; alternatively, gathered accordion-like hoses can be used, advantageously in a shape similar to an elongated bellows, or spirally shaped hoses.
  • the hoses may be coiled or in knots or coils such that they simply unroll or straighten out of the knots for elongation.
  • Fluid lines that go from the functional module to the outside and/or that come from the outside to the functional module are advantageously flexible or variable in length, as described. Fluid lines that run within the functional module between the individual components or functional units can be designed in a similar way, alternatively, it can also be formed by conventional elastic hoses or rigid or rigid tubes, possibly also by appropriately designed receptacles.
  • the function module has at least one additional filter, that is to say a total of at least two filters as mentioned above.
  • At least one coarse filter and one fine filter or microfiber filter can be provided.
  • the coarse particle filter should be designed to retain or filter out particles that are larger than 10 mm in one dimension.
  • a fine filter can filter out parts that have a dimension of more than 1 mm in one direction.
  • a microfiber filter can be made much finer and filter out microfibers. For a possible embodiment of such a microfiber filter is on the WO 2019/081014 A1 referenced, the content of which is made part of the content of the present description by express reference.
  • a general filter or a so-called additional filter can advantageously be designed in such a way that it has a filter housing with a filter unit inside. This allows a filter unit to be removed from the filter housing and replaced if clogged or in need of cleaning.
  • the functional module can have at least one sensor device.
  • a sensor device can in particular have a sensor which is designed to detect microfibers in the washing water and/or to detect other types of soiling in the washing water.
  • Another possibility is a sensor designed to detect cleaning agents or detergents and their concentration in the water. This can be important for a possible further or sufficient dosing of detergents, cleaning agents or additives for the washing process.
  • special filters can be activated or wash water can flow through them in order to remove the detected impurities or parts from the wash water.
  • the functional module can also have power electronics for a drive motor of a drum of a washing machine as a water-carrying household appliance.
  • power electronics can also be attached directly to the drive motor, it is then difficult to access in the event of repairs, as has been explained above.
  • their arrangement in the function module is also a big step towards making it easier to repair the washing machine.
  • electronics in the function module can also have communication and control electronics, which is intended at least for the functions of the functional module. It can therefore be used for communication and/or for controlling the functional module.
  • Such communication and control electronics can be implemented at least partially together with the aforementioned power electronics.
  • the functional module all of the electronic power components for the entire water-conducting household appliance are contained in the functional module.
  • This relates in particular to power electronics for the drive motor and also for pumps or valves.
  • control or power electronics for the aforementioned heating device can also be contained in the functional module, preferably also together with the heating device itself. Communication and control electronics for the entire household appliance can thus also be contained in the functional module.
  • the fluid lines can not be permanently installed at connections or at free ends or can be flexible and mobile.
  • these named connections can preferably be detachable water couplings, for example plug-in couplings or bayonet couplings.
  • the fluid lines can be detached in the event of repairs or for maximum mobility of the functional module, advantageously also completely out of the water-bearing household appliance.
  • the function module can have a heater for water that flows in one of the fluid lines.
  • water can be heated in this way before it is introduced or pumped back into the drum or into the washing compartment.
  • a heating device is advantageously arranged on the pump or integrated into the pump.
  • integration into the pump has the great advantage that efficiency can be significantly improved.
  • the number of necessary assembly steps and, above all, also connection steps can be reduced.
  • Such a pump is known from WO 2014/198427 A1 .
  • the functional module can have a supply fluid line, which can lead, for example, to the filter or to the aforementioned coarse-part filter.
  • This supply fluid line carries water that flows out of the drum or the washing compartment of the water-bearing household appliance or exits from these, either directly from the drum or from a sump in which the drum rotates.
  • a circulating fluid line can lead away from the functional module, whereby it can lead to a valve, in particular to an aforementioned three-way valve, or can have such a valve. Thereby can this valve can still be part of the function module, alternatively it is arranged outside of it in the household appliance.
  • valve or three-way valve is connected to an outlet from the pump by means of fluid lines. So water pumped by the pump goes into this valve.
  • An outlet of the valve or three-way valve can be routed to the filter or specifically to a coarse particle filter. For this purpose, a line for backwashing the filter can be connected to this output. If this filter is also arranged within the functional module, it is considered advantageous if the valve is also arranged within the functional module. Then the configuration of the fluid lines can be considerably simpler.
  • a valve or even an aforementioned three-way valve can be integrated into the pump.
  • a pump with a water switch can be created in which a number of functions are advantageously integrated. This makes the overall structure of the water-bearing household appliance less complex, especially its assembly.
  • a water-bearing household appliance is essentially characterized in that it has a functional module as described above.
  • it is a washing machine or a dishwasher.
  • This function module is formed in a module space, which can be designed as a type of module shaft, advantageously open to the front.
  • the functional module can be moved into this module space or module shaft, possibly pushed in and pulled out like in a kind of drawer.
  • the water-carrying domestic appliance advantageously has an operating device that is separate from the functional module.
  • it can be provided in the upper area, advantageously on a front side or top side of a housing of the household appliance.
  • the operating device is preferably also arranged above the drum or the washing compartment, so that it is easily accessible for an operator.
  • part of the operating device in particular a controller or a type of intelligence of the operating device, could also be arranged in the functional module. So this part can be repaired and in particular renewed and thus provided with additional functions. Operating elements that must be within reach of the operator can continue to be provided on the outside.
  • the water-carrying household appliance can have the functional module in a lower area, ie below the drum or the washing compartment.
  • an underside of the function module can run a maximum of 10 cm above an underside of the housing of the household appliance.
  • An underside of the functional module is advantageously arranged only a maximum of 2 cm above this underside of the housing.
  • the function module is arranged relatively far down in the household appliance, particularly advantageously as far down as possible.
  • only a housing bottom or a housing underside of the water-carrying household appliance can run underneath the functional module.
  • there is no housing base underneath the functional module but that it has a cutout. Only one frame part for better stability of the household appliance can be arranged below the functional module, advantageously in the front area.
  • the functional module is preferably arranged in the water-bearing household appliance in such a way that it can be moved forward out of it. This is advantageous for the reasons mentioned at the outset, namely that maintenance or repairs can then be carried out by pulling out the functional module without the water-carrying household appliance itself having to be moved.
  • the functional module is preferably designed to be horizontally movable, so that no special independent movements of the functional module due to gravity have to be taken into account.
  • it can be mounted in the household appliance on a rail guide so that it can be pulled out, for example similar to a drawer.
  • telescopic rails for the rail guide are advantageous here, as are known per se from the prior art, in particular for such drawers.
  • Such rail guides can also be designed to carry a weight of the functional module.
  • a support roller or the like at a front end. be provided, which runs on a floor when the functional module is pulled out.
  • the functional module advantageously has a width of at least 30% or even at least 50% of the width of the water-bearing domestic appliance, in particular at least 70% or 80%.
  • the functional module particularly advantageously occupies the entire width of the housing of the water-bearing household appliance. It is large enough to contain as many of the functional units or components mentioned as possible. Furthermore, the overall height of the function module can be reduced as a result, so that it fits well under a drum or a washing compartment in the household appliance.
  • the functional module can be designed in such a way that at least 50% of its length can be pulled out of the household appliance in the pulling direction, advantageously at least 70%. It can even be provided that the functional module can be pulled out of the household appliance by at least 90% or even completely. Then all components or functional units are easily accessible, in particular the fluid lines including connections. It can be provided that the functional module with the connected fluid lines can only be pulled out of the household appliance by 30% or 50% or 70%. In order to be able to pull them out further, these fluid lines must then be separated, for which purpose the aforementioned water couplings, which are advantageously designed to be self-locking, are well suited. After these water couplings have been released, the functional module can be moved completely out of the household appliance and removed without there being any risk of water running out or being lost.
  • the water-carrying household appliance can be designed in such a way that it has no valve which is not arranged in the function module or that all valves for the household appliance are arranged in the function module.
  • valves can generally be arranged on an outer edge, in particular on a rear outer edge, of the functional module.
  • valves can be arranged in the function module, but the water-bearing domestic appliance itself has a single additional valve.
  • This can in particular be a three-way valve, which also leads to a drain line away from the household appliance to a drain.
  • a fresh water line can lead into the water-carrying household appliance, specifically from the outside, and it can advantageously be brought in from a connection or tap arranged outside of the household appliance.
  • a fresh water line can be connected directly to the function module or can be led directly into the function module.
  • fresh water for example to be mixed with cleaning agent or for rinsing laundry in the drum, can be fed into the function module and pumped on by means of its pump.
  • a fresh water line can be a single line, which is then advantageously only a cold water connection.
  • a fresh water line can also have two lines or be formed by two lines, namely a cold water connection and a hot water connection. Such an additional hot water connection means that the household appliance can be operated more quickly and in a more environmentally friendly manner.
  • An aforementioned circulation fluid line of the functional module can be connected to an inlet fluid line by means of at least one valve device.
  • This inlet fluid line leads into the drum or wash cabinet, advantageously with a water outlet located in the top of the drum or above it, alternatively in a known manner at a wash cabinet. Water can thus be introduced from above into the drum onto the laundry or objects located therein, in particular sprayed or sprayed with pressure by means of the pump and not just simply run out or run into the drum. In this way, an overall process optimization can take place, possibly above all a cleaning effect can be improved.
  • the functional module can have a front panel that forms a continuous surface with the rest of the front of the water-bearing household appliance.
  • this relates to the shape or course and color of this area. It is thus possible for the functional module to form a part of the household appliance that is recognizable from the outside only with the front panel or a parting line surrounding it.

  • electrical connections, in particular cables, to the functional module are designed in such a way that they can remain connected while the functional module is moved up to 30% or up to 50% out of the household appliance. Cables or electrical connections can then be separated by means of appropriate plugs so that the functional module can be moved out even further.
  • the cables can also be designed and arranged in such a way that they allow the functional module to be moved completely out of the household appliance without being detached, since such cables can be designed to be thinner and therefore possibly more flexible than fluid lines.

  • the wound up supply line is correspondingly unwound. Due to the spring loading of the drum, it is wound up again when the function module 30c is pushed back into the housing 12c.
  • FIG. 6 Another embodiment of a functional module 30d is shown with front panel 31d, circulating pump 33d, filter 40d and auxiliary module 45d.
  • the functional module 30d is similar to that of FIG 4 .
  • a water connection is made here with a supply line 52d, which is designed like a bellows and can therefore be stretched directly.
  • supply line 52d which is designed like a bellows and can therefore be stretched directly.
  • Such lines are known, especially in the field of water-bearing household appliances. They have the great advantage, as can be seen by comparing the Figures 6 and 7 can be seen, where in 7 the function module 30d is pulled to the left out of the housing 12d shown in dashed lines, so that they can lengthen themselves relatively considerably.
  • a guide roller 65d is also provided here for better guidance of the supply line 52d, especially when it is increasingly under tension when the functional module 30d is pulled out.
  • a bellows line can be similar to a clamping device Figures 4 and 5 be dispensed with, which could simplify the structural design. On the other hand, however, dirt can settle more easily in such a bellows-like line.
  • FIG. 8 Another washing machine 30e according to the invention is shown, similar to that of FIG 2 .
  • This washing machine 30e does not have an upper drawer 18e for detergent.
  • a metering device 46e is provided in a functional module 30e in addition to a filter 40e and a circulating pump 33e. It can thus form a concrete example, so to speak, of an aforementioned auxiliary module. Water from the supply line 52e from the drum receptacle 14e enters the functional module 30e and is first filtered there in the filter 40e.
  • the distribution valve 60e which is designed as a three-way valve, it can be seen that the circulating pump 33e waste water also through the lower region of the circulating line 54e and to the right through the drain line 56e out of the washing machine 30e into a drain.
  • the advantage of conducting the fresh water through the filter 40e is, of course, that this water can also be filtered again.
  • a backwash line 69e leads back to the left to the filter 40e.
  • the filter 40e or partial filter thereof can be backwashed in order to clean it. Flushed contaminants can then be flushed out of the washing machine 30e, for example, through another line (not shown) at the outlet.
  • Telescopic rails 32a are arranged on both lateral sides, as are known per se from drawer pull-outs from furniture construction.
  • the telescopic rails 32a have an outer rail guide and an inner telescopic rail.
  • the telescopic rails which are continued on the right in dashed lines, are fastened inside the washing machine 11 by means of fasteners 34a.
  • the front panel 31a protrudes beyond the telescopic rails 32a, so that when pushed in accordingly 1 actually only the front panel 31a is visible, but not the rest of the function module 30a.
  • the extent to which the telescopic rails 32a allow the functional module 30a to be pulled out depends on their construction. They can be double or triple telescopic, allowing up to 100% extension, although this is not essential.
  • the telescopic rails 32a should of course be sufficiently stable so that they can bear the weight of the functional module 30a when pulled out.
  • One option here could be to attach a support wheel that can be moved downwards and is advantageously foldable or pivotable on the underside near the front panel 31 . This support wheel can then run on the floor when the functional module 30a is pulled further out of the washing machine 11 . Since according to the 1 the function module 30a is only a few cm, for example between 5 cm and 2 cm, above a floor, such a guide wheel with small dimensions and without great effort can be installed here.
  • FIG. 11 Another possibility is shown of how quick couplings can be used in a function module 30e instead of the extendable lines described above.
  • a function module 30e with a filter 40e, a dosing device 46e and a circulating pump 33e, connections for a supply line 52e and a fresh water line 58e are provided.
  • a quick coupling 70e is provided at the end of the supply line 52e.
  • the quick coupling 70e has a line part 71e at the end of the supply line 52e.
  • a fixed part 72e, from which a coupling nipple 73 protrudes, is fixedly mounted on the filter 40e, into which the supply line 52e is routed.
  • the line part 71 is slipped onto this coupling nipple 73e.
  • the supply line 52e can be automatically closed by the line part 71e if a coupling nipple 73e is not currently inserted.
  • the quick coupling 70e is located with one part, namely the fixed part 72e including the coupling nipple 73, directly on the functional unit of the functional module 30e, namely on the filter 40e.
  • the fresh water line 58e has the quick coupling 70e at the end shortly after it has run into the functional module 30e.
  • a line part 71e is fastened to the end of the fresh water line 58e, similar to that described above for the supply line 52e.
  • the lines do not have to be able to compensate for as much difference in length as in accordance with FIG Figures 4 to 7 . It is sufficient here that they are flexible enough for the functional module 30e to be pulled out of the washing machine 11 far enough for the quick coupling 70e to be released. The same applies to the quick-release coupling 70e on the fresh-water line 58e after the quick-release coupling 70e on the supply line 52e has been pulled out further.
  • claw couplings or other couplings can also be used.
  • a filter 40f is also shown, into which a feed line 52f leads.
  • a sensor 50f is arranged on this supply line 52f, which can be connected to a corresponding sensor control or a general control of the washing machine.
  • a fresh water line 58f comes to the supply line 52f via a fresh water valve 67f. In this way, fresh water can be supplied and also filtered at the same time.
  • the filter 40f is designed as a functional unit or also as a structural unit and is shown here, it also being arranged in a functional module 30 according to the invention.
  • the sensor 50f is advantageously also located within this functional module, which is not shown here, so that it can easily be provided and electrically connected to a controller, which can be present in the functional module as described above.
  • the sensor 50f can be designed to examine water that drains from the drum or from the drum receptacle of the washing machine with regard to a number of well-known criteria. Further sensors can of course be provided, for example behind one of the partial filters.
  • the feed line 52f leads into a coarse part filter 41f. This is advantageous with a grid or the like. or mesh to filter out the aforementioned larger objects or coarse parts. After that, the coarsely filtered water continues to flow into the fine filter 42f. This is also designed as described above with a fine filter fabric or the like.
  • the now finely filtered water emerges from the fine filter 42f and can be passed on by means of a filter valve 44, which is designed as a three-way valve. Microfibers in the water can also be detected behind the fine filter 42f, for example by the sensor 50f or a downstream sensor. Then the water is passed through a microfiber filter 43f by means of the filter valve 44, which can even filter out microfibers.
  • the clean water that has been filtered very well leaves the filter 40f by means of the circulation line 54f.
  • More or fewer filter units can be provided here, as is easy to imagine.
  • the backwash line 69f is shown as it is used for 8 has been explained.
  • the backwash line 69f leads to corresponding backwash connections both on the coarse filter 41f and on the fine filter 42f.
  • the pump not shown here, can pump water through for backwashing said filters and, for example, to a drain from the washing machine.
  • This is advantageously solved differently for the microfiber filter 43f, since the microfibers should if possible not get back into the water cycle, i.e. cannot be flushed out to the drain.
  • To clean the microfiber filter 43f it can be removed from the functional module, which is easy according to the invention thanks to the pull-out functional module.
  • the microfiber filter 43f can either be exchanged and replaced with a new fresh filter.
  • the components filtered out can be disposed of correctly and professionally, so that the microfiber filter 43f can, so to speak, be reused after cleaning.
  • this type of cleaning is it is of great advantage if the microfiber filter 43f can be easily removed and is therefore easily accessible.
  • the location close to the circulation pump is also of great advantage, which is why the microfiber filter 43f as well as the entire filter 40f at a short distance is of great advantage.
  • a dishwasher 11g according to the invention as a water-bearing domestic appliance according to the invention is shown in a further embodiment of the invention in a sectional front view.
  • the dishwasher 11g has a housing 12g with a washing chamber 19g arranged thereon, which has a sump 20g at the bottom.
  • a standard basket K with crockery in it is arranged in the washing compartment 19g.
  • a standard spray arm 21g is below that is a standard spray arm 21g.
  • a coarse particle filter 41g is provided at the top of the sump line 53g, for example in the form of a grid. Together with an adjoining fine filter 42g, it forms the filter 40g of the dishwasher 11g.
  • a supply line 52g goes to the right from the sump line 53g to the function module 30g. Only one circulating pump 33 and one pump valve 35 are shown here for the function module 30g. However, it is easy to imagine that the same functional units as described above for the washing machine can also be provided here, for example also a similar dosing device 8 . Furthermore, a drain line 56g branches off to the left from the sump line 53g. To the right, a recirculation line 54g goes upwards out of the functional module 30g. This goes on the one hand to the left to said spray arm 21g, on the other hand further up to another spray arm, not shown. Furthermore, a backwash line 69g leads from the function module 30g back to the filter 40g. As has been described above, this backwash line 69g serves to backwash filters by means of a flow which has been generated by the circulating pump 33g.
  • the invention can be provided not only in a washing machine as a water-carrying household appliance, but also advantageously in a dishwasher.
  • a washing machine as a water-carrying household appliance
