Water supply device for a liquid and / or ice dispensing unit of a household refrigeration appliance with a specific carrier with a holding structure, as well as household refrigeration appliance so that

Description

[0001] The invention relates to a water supply device according to claim 1 for a liquid and / or ice dispensing unit of a household refrigeration appliance. The water supply device has a support. This support is intended to support at least one pump of the water supply device and / or at least one hose of the water supply device.

[0002] It is known that household refrigeration appliances, such as refrigerators, freezers, or combination refrigerator-freezers, may include a liquid and / or ice dispensing unit. This allows water or water-based beverages to be dispensed. It is also possible for the provided liquid, particularly water, to be used to produce ice. This ice can be ice cubes or crushed ice. This ice can then also be dispensed via the corresponding dispensing unit. In this context, household refrigeration appliances are known that, for example, have a dispensing device on the outside of the appliance door. A recess may be arranged in the outside of the door for this purpose. A container can be placed in this recess to hold the liquid and / or ice to be dispensed.Household refrigeration appliances of the type described are known, for example, from US 2021 / 180853 A1 or also from US 2022 / 034581 A1.

[0003] In known water supply systems, it is known that level detection is performed in a water tank of the water supply system. Sensors may also be provided for this purpose. Such sensor detection is known, for example, from US 10,794,628 B2. US 2008 / 168791 A1 discloses a household refrigerator with a water supply system that has several separately designed collection trays for water, wherein sensor detection of the current fill level of one or more of the separate collection trays also takes place.

[0004] Another state of the art is known from document KR100776295B1.

[0005] The object of the present invention is to create a water supply device in which a compact design is achieved and various functional units can be arranged in a space-saving manner.

[0006] This problem is solved by a water supply device according to independent claim 1.

[0007] The invention relates to a water supply device for a liquid and / or ice dispensing unit of a household refrigeration appliance. The water supply device according to claim 1 has a support for carrying at least one pump of the water supply device and / or for carrying at least one hose of the water supply device. The support has at least one retaining structure for carrying the at least one pump of the water supply device and / or for carrying the at least one hose of the water supply device. This retaining structure has at least one water basin. Thus, this water supply device is provided with a water basin on the support. This provides such an intermediate reservoir for water along the water path between a water tank of the water supply device and an outlet.This advantageously allows for the equalization of hydrostatic pressure, particularly when the water tank is located higher than the outlet of the water supply unit. In a particularly advantageous embodiment, this prevents unwanted dripping of liquid from this outlet into, for example, an ice tray of the liquid and / or ice dispensing unit. This avoids unwanted overflowing and / or complete freezing of the ice tray.

[0008] The water basin is integrated into the support structure. In one embodiment, the support structure can be freely cantilevered from a base body of the support, particularly a frame-like base body. Preferably, at least one retaining claw, and in particular several retaining claws, are arranged on the water basin for holding hoses and / or at least one pump of the water supply system. In particular, this at least one retaining claw is freely cantilevered on the water basin. It can be provided that this at least one retaining claw extends into a space between a support arm of the support and the separate and spaced-apart support structure.

[0009] In one embodiment, the retaining claws have claw openings. In this embodiment, these openings are oriented upwards in the vertical direction of the water supply device. This allows for particularly easy insertion of a hose and / or pump from above. A very simple assembly scenario with clearly defined assembly steps is thus enabled. It is also particularly advantageous in this context that a pre-assembled module with at least one hose and at least one pump is produced, which are then already pre-assembled together. This pre-assembled module can then be very easily inserted from above into the retaining claw.

[0010] In one embodiment, the water basin has a boundary wall, in particular a boundary wall facing a support arm of the beam. This boundary wall, in particular, has a passage for a hose. Specifically, the passage is located at an upper edge of the boundary wall. It is designed, in particular, as an upwardly open recess for receiving and passing through a hose. This also provides a simple holding and mounting solution for a hose that is to be mounted directly to this boundary wall. Both inserting and removing this hose from this passage is thus very easy. Nevertheless, a stable fit of the hose to this boundary wall is achieved.

[0011] The invention relates to a water supply device according to claim 1 for a liquid and / or ice dispensing unit of a household refrigeration appliance. The water supply device has a support. This support is intended to support at least one pump of the water supply device and / or at least one hose of the water supply device.

[0012] The carrier also features a holding unit. This is designed to hold a sensor unit of the water supply system in a way that allows for non-destructive removal.

[0013] The invention thus provides a multifunctional support for a specific assembly of a liquid and / or dispensing unit, namely the water supply system. This support is designed to accommodate both water delivery components, such as a pump and / or a hose, and a detection device, particularly the sensor unit. This allows for the arrangement of a wide variety of components of the water supply system on this multifunctional support, resulting in a space-saving design. Furthermore, the individual components can be mounted in such a way that their functions are not restricted or mutually limited. A detachable connection for attaching a sensor unit to this support is particularly advantageous.This mounting unit allows for the reversible attachment and removal of such a sensor unit. This means the sensor unit can be removed for maintenance or replacement purposes. Consequently, this assembly process is very easy to carry out.

[0014] In one embodiment, the support is formed in one piece. This means, in particular, that it is manufactured in a single production process. In this context, the overall geometry of the support is formed during this manufacturing process. One-piece manufacturing, therefore, does not mean that individual components of the support are first manufactured separately in their basic form and then subsequently joined together, for example, by gluing or similar methods. One-piece formation of the support can be achieved, for example, by injection molding. In such an embodiment, the support is then an injection-molded component. The support is made, in particular, of plastic. This allows it to be produced with low weight. Furthermore, this material is robust against a wide variety of environmental influences, including those that fluctuate significantly, and is therefore also wear-resistant.A carrier made of metal, especially a one-piece carrier, is also possible, particularly as a bent and / or stamped and / or embossed component.

[0015] In one embodiment, the holding unit has at least one recess into which the sensor unit can be inserted, at least partially. This improves the positioning of the sensor unit on the holding unit. It allows for the sensor unit to be embedded, at least partially. Additionally, this concept also enables the sensor unit to be positioned in a way that protects it, at least partially.

[0016] In one embodiment, the receptacle has at least one receiving rib. In one embodiment, this rib has a support surface for the sensor unit. Such a receiving rib is compact in design yet mechanically robust. This allows it to require little space while still being sufficiently durable. The support surface can be designed as a ring section. This enables the insertion and precise positioning of the sensor unit. In particular, this allows for a strip-like contact between the sensor unit, especially with its housing, and the support surface. A positive-locking connection can also be achieved.

[0017] In one embodiment, the mounting has at least two separate mounting ridges. Each of these can be designed with a corresponding support surface. This allows for a further improvement in the secure positioning of the sensor unit. Nevertheless, a very compact and lightweight mounting unit is still provided.

[0018] Especially when the sensor unit is elongated, several mounting brackets, arranged separately and spaced apart from each other, can still enable secure and accurate mounting and holding of the sensor unit.

[0019] In one embodiment, the holding unit has at least one snap-in element for securely holding the sensor unit. This is an advantageous embodiment for non-destructively releasable holding of the sensor unit, as it ensures particularly secure positioning of the sensor unit in its installed state. Furthermore, it allows for quick assembly and disassembly. These advantages of rapid assembly and disassembly are especially noteworthy when even a single snap-in element is provided. Such a snap-in element can be designed as a freely cantilevered tongue. This tongue can then snap directly onto the housing of the sensor unit when it is installed in the holding unit. This makes the fundamental design of this snap connection geometrically and functionally very simple.

[0020] In one embodiment, the snap-in element is a separate component from the at least one mounting ridge. It can also be arranged at a distance from the mounting ridge. This concept improves the mechanical stability of the mounting, as different components of the mounting unit directly engage at different points on the sensor unit.

[0021] Last but not least, this also improves the handling and accessibility of the individual components of the holding unit.

[0022] In one embodiment, the holding unit has a stop wall. This is designed to provide abutment positioning for a stop lug of the sensor unit. This is particularly relevant when the sensor unit is in its final, mounted position on the carrier. This additional stop connection further improves the positional accuracy of the sensor unit within the holding unit. Specifically, the stop wall is a distinct component from the snap-in element and the receiving lug. This allows for the creation of an additional mechanical connection between the holding unit and the sensor unit through direct contact between the stop lug and the stop wall. This further improves the positional stability and enables a very precise final position of the sensor unit on the carrier, which can then be maintained permanently.This improves the consistently reliable and accurate detection with the sensor unit.

[0023] In one embodiment, the support has a base body. In particular, this base body is frame-like. Preferably, the support can have a support wall. This wall differs from the base body. It can be provided that this support wall projects from the base body. The retaining unit is, in particular, completely attached to the support wall. This prevents the base body from being affected by such additional components of the support. In this context, the base body can then be fully coupled to other units, for example, an insert for a household refrigerator. In this context, no retaining units or other components of the support are in the way. Furthermore, positioning the retaining unit on the support wall also allows for a more exposed mounting. This improves both accessibility and mechanical stability.

[0024] In one embodiment, the support wall is formed as a stiffening strip, particularly one with multiple angles. This increases the stiffness of the support itself. In particular, it can also stiffen the frame-like base body. Because the support wall is also designed as a strip, it has a compact structure in the direction perpendicular to the plane of the base body. The strip geometry also means that the dimensions of this support wall perpendicular to its longitudinal axis are smaller than its length along this longitudinal axis.

[0025] In one embodiment, the water supply system includes at least one sensor unit. In particular, the sensor unit can be a reed switch. Such a sensor unit is very simple in design yet reliably functional and robust in its detection capabilities. Specifically, such a reed switch can be opened and closed by the influence of a magnetic field. Therefore, it is very advantageous and easily implemented to arrange such a detection element, for example, a magnetic float, in a water tank of the water supply system. Depending on the liquid level in the water tank, this float rises or sinks vertically. Thus, through the interaction between this detection element and the reed switch, a simple yet reliable and safe concept for level detection can be achieved.

[0026] By ensuring that this sensor unit, which can be a level detection sensor unit in particular, is detachably held or installed on this carrier, an accurate level determination can be achieved permanently.

[0027] According to the invention, the water supply device has a water tank that is separate from the carrier. In particular, its fill level with liquid, especially water, can be detected by the aforementioned sensor unit.

[0028] In one embodiment, the support has a counter-coupling device. This is designed for coupling with a coupling device. The coupling device is specifically formed on an insert of the domestic refrigeration appliance, separate from the water supply unit, so that the support can be attached to this insert. In particular, it is provided that the support is freely supported and can be directly attached to the insert. A non-destructively detachable connection can also be provided here. Thus, the support provides an additional function. In this context, it is therefore a central component of the water supply unit. Indeed, in the aforementioned embodiment, it is precisely the central component that is to be mechanically connected directly to this insert.This allows the carrier to provide and absorb these corresponding holding forces, even if it is already extensively equipped with other components, such as a pump and / or hoses, as well as the sensor unit.

[0029] In one embodiment, the support has at least one retaining arm for holding at least one hose of the water supply system. This retaining arm is, in particular, cantilevered. In one embodiment, the retaining arm projects from a frame-like base body of the support. Such a retaining arm, when positioned and oriented, simplifies the mounting of components to the support. Nevertheless, the retaining arm is stably mounted to the frame-like base body. Due to its cantilevered position, the retaining arm is also accessible from various angles and can accommodate additional components at different locations. In particular, such a retaining arm is also sufficiently load-bearing and serves as an advantageous support component for corresponding additional components.Due to the exposed orientation, other components can also be easily handled while attached to the support arm and are therefore easily accessible.

[0030] According to the invention, the support has at least one water basin. This water basin is integrated into the support. This means that the water basin is formed integrally with the support. Such a water basin or reservoir advantageously prevents unwanted water from flowing into an ice tray of the liquid and / or dispensing unit. In particular, if a water tank of the water supply unit is positioned higher than this ice tray, the corresponding pressure conditions, especially hydrostatic pressure, can cause water to leak or drip from the hoses leading from the water tank to the ice tray, even if the ice tray is already sufficiently full. Such unwanted leakage or dripping can lead to the ice tray overflowing.By including a water basin between the water tank and the ice tray in the hose system, pressure regulation can be improved, effectively preventing liquid from dripping into the ice tray. The larger volume of the water basin, compared to the downstream hoses, advantageously equalizes the pressure between the higher water tank and the lower ice tray, thus preventing the previously described dripping into the ice tray. The water basin can therefore also be referred to as a pressure equalization chamber or dosing chamber. Integrating this water basin into the support structure also reduces the number of components.This eliminates the need to provide a separate water basin, which would have to be mounted to the support structure through a specific assembly process.

[0031] This embodiment is particularly advantageous when the water basin also serves as a support component for the support structure. In this context, the water basin can, for example, be integrated into a support structure of the support structure.

[0032] This holding structure serves, on the one hand, to accommodate further components of the water supply system, such as a pump and / or at least a hose, but on the other hand, it also serves to temporarily store the water on its way from the water tank to an ice bowl.

[0033] In one embodiment, such a water basin is essentially integrated into such a support structure, in particular a specifically designed support arm. In one embodiment, this water basin can be arranged directly on a base body, especially a frame-like base body, of the support. In another embodiment, the water basin can be cantilevered freely from this base body. This allows the advantages already explained above for the advantageous embodiment with the support arm to be achieved with this water basin as well.

[0034] In one embodiment, the support arm can be provided in addition to the water basin. These components can then be arranged at a distance from each other, in particular, each cantilevered freely from the base body. They can also be arranged projecting from the base body in the same direction. In an advantageous embodiment, this creates a space or air gap between the support arm and the water basin, allowing for the compact yet highly functional arrangement of additional components of the water supply system. This enables at least one pump and / or at least one hose to be compactly and securely positioned within this space. It is particularly advantageous that these additional components are suspended within this space.This can be achieved, for example, by providing the support arm with corresponding recesses, particularly indentations, into which a hose can be inserted. The water basin can also have such a recess, particularly an opening, at least on one boundary wall, into which at least one hose can be inserted and secured. This allows these additional components to be suspended from the support arm and / or the water basin.

[0035] In an advantageous embodiment, the support has at least one, and in particular several, separate retaining claws. These retaining claws are designed to hold one or more hoses of the water supply system and / or at least one pump of the water supply system. In this context, a retaining claw is a component that at least partially encompasses a hose and / or a pump. Thus, a retaining claw has at least two retaining fingers that partially encompass the object to be held. In one embodiment, a retaining claw can be a freely cantilevered rib at the end of which these claw fingers are arranged. Such retaining claws are then arranged in an exposed position, enabling a particularly simple assembly scenario. Due to the advantageous accessibility, a hose and / or a pump can then be very easily inserted into the retaining claw.In particular, the retaining claw is designed so that a hose and / or a pump component are held securely within it. A friction-based connection is also possible. In this case, a clamping force can be generated, which holds the hose and / or pump component firmly in the retaining claw. This ensures a particularly stable and secure fit. Even during operation of the water supply system, especially when a pump is running, the respective position is maintained securely, even when vibrations occur due to pump operation.

[0036] In one embodiment, these preferably multiple retaining claws are integrated into a support arm. Additionally or instead, one or more retaining claws can be integrated into a boundary wall of the water basin. In particular, a retaining claw is arranged in the free space, as described above, which can be formed between a support arm and the water basin in the support structure. This further improves the secure and easy installation of these additional components in this free space between the support arm and the water basin.

[0037] Another aspect of the invention relates to a liquid and / or ice dispensing unit for a household refrigeration appliance. The liquid and / or ice dispensing unit comprises a water supply device according to one of the following claims. The liquid and / or ice dispensing unit may additionally comprise a dispensing device. This is provided for the direct dispensing of the liquid and / or ice. This dispensing device may, for example, be arranged on a door of the household refrigeration appliance. It may be arranged in a recess of the door that is open on the outside. The liquid and / or ice dispensing unit may also comprise an ice production unit. This is a separate unit from the water supply device of the liquid and / or ice dispensing unit. The liquid and / or ice dispensing unit may also comprise an ice tray. With this ice tray, introduced water can be frozen, for example, into ice cubes.

[0038] The liquid and / or ice dispensing unit may also include a conveying unit with which produced ice, such as ice cubes or crushed ice, which is temporarily stored in a storage trough, can be conveyed to the dispensing device.

[0039] Another aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a water supply device according to one of the following claims. The household refrigeration appliance may also have a liquid and / or ice dispensing unit. The water supply device has a water tank. This tank is reversibly removable and replaceable. This allows it to be filled externally by a user with liquid, in particular water, separate from the household refrigeration appliance. For example, this can be done at a tap.

[0040] One aspect of the invention relates to a water supply device according to claim 1 for dispensing liquid and / or ice from a household refrigeration appliance. The water supply device comprises a support. The support is designed to carry at least one pump of the water supply device and / or at least one hose of the water supply device. The support has at least one, in particular cantilevered, retaining arm. The retaining arm is designed to hold at least one hose and / or at least one pump. In particular, these components can be arranged directly on the support. Furthermore, the support has a base body. This base body is in particular frame-like. The retaining arm projects from this base body.

[0041] In one embodiment, the support arm has a receptacle at its upper edge for a hose and / or a section of the pump. This allows the support arm to receive the hose and / or pump from above. It is therefore very easy to mount the hose and / or pump to the support arm from above. This ensures easy access and yet stable positioning of the aforementioned components on the support arm. In particular, the receptacle is open at the top. This creates a trough-like or ring-shaped recess in the upper edge of the support arm.

[0042] One aspect of the invention relates to a household refrigeration appliance according to claim 13 with an outer casing. The household refrigeration appliance also has an inner container. The inner container is a component separate from the outer casing. In particular, the inner container is housed within the outer casing. In one embodiment, the inner container defines at least one receiving space for food. This receiving space is an integral part of the household refrigeration appliance. Furthermore, a space is formed between the outer casing and the inner container. This space is intended for filling with thermally insulating material of the household refrigeration appliance. The household refrigeration appliance also has an insert. This can also be referred to as a backing element. The insert is arranged in the space in the area of ​​an opening formed in a wall of the inner container. The insert has a coupling device.The household refrigeration appliance further comprises a water supply unit according to claim 1. The water supply unit is part of a liquid and / or ice dispensing unit of the household refrigeration appliance. In one embodiment, the water supply unit includes a feedback device. This is intended for coupling with the coupling device when the water supply unit is mounted on, or is already mounted on, the insert. In particular, the coupling device and the feedback device are designed such that at least one component, in particular a support, of the water supply unit is freely supported on the insert and is also arranged in the receiving space.This means that with this specific structure, at least one component of the water supply system is held in place solely by the holding forces between the coupling device and the counter-coupling device, without any additional support or bearing beneath the component. It is also possible for this component, particularly the water supply system, to extend freely into the receiving space and be held in place by the direct mechanical coupling between the coupling device and the counter-coupling device. This enables a particularly advantageous mounting concept for the water supply system, as a specific insert serves as the component to which the water supply system can be directly mounted.By designing the coupling and counter-coupling devices to absorb the weight of the water supply unit, additional support elements and mounting components, on which the water supply unit would otherwise rest, are unnecessary. This also reduces the number of components and enables a simpler and faster installation process. Furthermore, it allows the water supply unit to be positioned very precisely within the domestic refrigeration unit and to be permanently secured. The weight and leverage forces acting on the insert can be effectively absorbed.This makes it particularly advantageous to allow other components of the liquid and / or ice dispensing unit, which are also located adjacent to and / or directly connected to the water supply unit, to be easily removed without damaging the connection between the water supply unit and the insert. Similarly, removing components located vertically below the water supply unit and / or from below the component directly connected to the insert does not damage this connection interface, especially the attachment interface, between the insert and the water supply unit component.The coupling device and the counter-coupling device are mechanically so stable and robust in this context that the position of the water supply device in its freely cantilevered extension and in its freely supporting arrangement on the insert remains permanently intact.

[0043] In one embodiment, the coupling device extends through the opening into the receiving space. This also places it in a more exposed position, making direct coupling with the counter-coupling device easier. Particularly when the water supply device, especially the aforementioned component, is brought into contact with the insert and directly connected to it, this position of the coupling device simplifies the coupling process, especially the mechanical one, and makes it easier to precisely achieve the coupled end position.

[0044] In one embodiment, the coupling device has at least one coupling rail. The component can be directly attached to this rail. A coupling rail is, in particular, an elongated component. This allows for increased mechanical coupling with the feedback device. Specifically, this improves the connection between the coupling device and the feedback device. The component's weight forces can thus be transferred to or absorbed by the coupling device over a larger area. Furthermore, while such a rail can be relatively long in one spatial direction, it is relatively compact in the other two. Therefore, a space-saving arrangement is possible, at least in these other two directions.

[0045] In one embodiment, the coupling device has several, in particular two, separate coupling rails. This improves the mechanically stable connection with the counter-coupling device. The absorption and dissipation of corresponding weight and leverage forces is thereby further improved.

[0046] Preferably, at least one coupling rail can have an L-shaped cross-section. The cross-section is preferably perpendicular to the longitudinal axis of the coupling rail. This shape of the coupling rail creates a simple geometry. Furthermore, it enables quick yet stable coupling with a counter-coupling device. In particular, the counter-coupling device can be easily and securely attached to such a coupling rail from above. This effectively prevents the counter-coupling device from slipping or sliding out of the coupling rail. Moreover, attaching the counter-coupling device to such a coupling rail from above also allows for improved absorption of weight and leverage forces.

[0047] In particular, the coupling rail, with its L-shape, is oriented such that one leg of the L points upwards and cantilevers freely upwards. This creates a receiving area into which the feedback device can be inserted. This further improves suspension connections, as the upward-projecting leg of the L-shape prevents the feedback device from slipping out.

[0048] In one embodiment, the coupling device has at least one positioning dome. This dome can be inserted into a dome receptacle of the feedback device. This insertion creates at least one plug connection. This further improves the positional accuracy of the coupling device and the feedback device relative to each other. Furthermore, it also simplifies assembly, as the positioning dome and the dome receptacle can also incorporate an assembly code.

[0049] In one embodiment, the positioning dome is additionally designed as a screw dome. This allows for an additional screw connection between the insert and the component of the water supply system to be directly connected to it. The screw connection improves the permanent, precise positioning of the component on the insert, and thus also of the water supply system on the insert.

[0050] In one embodiment, the coupling connection between the coupling device and the counter-coupling device can be detached without damage. This allows for reversible assembly and disassembly of the water supply unit on the insert. For maintenance, cleaning, and / or replacement work, the entire water supply unit can therefore be removed from the insert and subsequently reattached.

[0051] In one embodiment, the component of the water supply system that is attached directly to the insert can be a support. This support can be designed to carry at least one pump of the water supply system and / or at least one hose of the water supply system. Thus, in one embodiment, a central component of the water supply system is also the component that is directly connected to the insert. This robust component therefore not only serves to accommodate other components of the water supply system but also represents the interface to the insert.

[0052] In one embodiment, the insert has at least one retaining element. This element extends, in particular, into the receiving space. The retaining element spans the clear width of the opening, so that it overlaps those areas of the inner container wall that border or define the opening. This provides a very simple way to attach the insert to the inner container wall in the area of ​​the opening. In particular, this enables a self-retaining connection of the insert to the wall. The retaining element can be integrated into the insert. The insert can, for example, be a plastic part or an injection-molded component. By forming the retaining element integrally with the insert, the number of components is reduced.The retaining element can be designed to be mechanically stable with the insert. This allows it to absorb corresponding forces and avoids positional tolerances of the retaining element.

[0053] In one embodiment, at least one retaining element is designed as an elongated retaining rail. In another embodiment, this elongated retaining rail can be formed on a base body of the insert, creating a receiving groove for the surface area between the retaining rail and the base body. The surface area then slides into this receiving groove, ensuring a stable fit of the insert. Since this surface area is surrounded on both sides by sections of the insert, a stable fit of the insert against the wall is also achieved. This embodiment makes the installation of the insert particularly easy. With a simple relative movement between the insert and the wall, the surface area can be inserted into this receiving groove, thus precisely achieving the desired final position of the insert against the wall in the area of ​​the opening.Furthermore, such a geometry also prevents the insert from undesirably detaching from the wall.

[0054] Preferably, the opening has at least one threading area. This threading area has a larger clear opening than the opening area adjacent to it. This locally limited widening of the opening allows for a particularly simple installation of the insert on the wall. It makes it very easy to insert the insert into the opening from one side of the wall, such that the retaining rail is inserted into the threading area from that side and can then be moved through the opening to the other side of the wall. Thus, when installing, and especially moving, the insert, this retaining rail is pushed through this threading area so that it is then positioned on the opposite side of the wall.As the insert is moved further in this linear mounting direction, the surface area, which is already slightly inserted into the receiving groove, slides further into this groove until the insert reaches its final position on the wall. This simple mounting scenario is made possible in particular by this widened insertion area. This eliminates the overlapping position between the retaining rail and the surface area that exists in the opening.

[0055] In one embodiment, the clear width of the threading area is at least as large as the distance between a free edge of the retaining element and an opposite area of ​​the insert. In particular, this clear width of the threading area is at least as large as the distance between a free edge of the retaining element and another free edge of a further retaining element. This makes it possible for the retaining element to be slid from one side of the wall through the threading area to the opposite side of the wall when the insert is mounted to the wall by a sliding motion.

[0056] In one embodiment, one end of the retaining element, particularly in the direction of its longitudinal axis, is flared. Specifically, this end is designed as a threading end. This flared end greatly simplifies the assembly process described above, as it creates a funnel-shaped inlet at this end of the retaining element. This facilitates the insertion of the retaining element from one side of the wall through the opening, particularly in the threading area. Jamming, spreading, or unwanted impact is thus effectively prevented. This flared end also simplifies the handling of the transition, especially the abrupt one, between the threading area and the wider opening.This also makes it easier to further insert the surface area into the receiving groove when the insert is moved further relative to the wall.

[0057] One aspect of the invention relates to a household refrigeration appliance according to claim 13, comprising an outer casing and an inner container which is housed in the outer casing and which defines a storage space for food. The household refrigeration appliance has a space formed between the outer casing and the inner container, which is intended for filling with thermally insulating material. The household refrigeration appliance has an insert which is arranged in the space in the area of ​​an opening through a wall of the inner container. The insert has a base body, in particular a plate-like one, which has at least one hole to which at least one pipe section of the insert, projecting into the space, is formed. The pipe section is designed as a coupling for a hollow part of the household refrigeration appliance. This enables the insert to be used as a multifunctional component.It serves as an interface between the receiving chamber and the space between the components, allowing for their connection. With the integrated coupling spigots, it is now possible to couple hollow parts to the insert independently of the base body itself. This improves the routing of components within the space between the components and in close proximity to the base body. The routing of cables and hoses carrying media is thus more precise. Especially at the transition to the hole in the base body, the coupling spigots enable more accurate component placement. This also improves the connection to the hollow parts, making it more leak-free. Directly connecting these hollow parts to pipe fittings is simpler and more stable.

[0058] The coupling fitting can have a coupling structure. This is intended for coupling, particularly mechanical coupling, with an additional part. The coupling structure can have a thread. It can also have a snap-fit ​​or bayonet fitting. A quick-connect coupling for easy assembly with the additional part is also possible. This is advantageous when an extension is to be formed as a hollow section on the coupling fitting, so that the coupling fitting and the hollow section, in particular a conduit, form a routing channel for another component. The other component can be, for example, a hose. However, it is also possible for a hollow section in the form of a hose to be coupled directly to the coupling structure. Then the medium, for example, water, flows directly in this channel. An additional conduit in which the separate hose is laid is then not required.

[0059] In one embodiment, the hollow part is a conduit for receiving a separate hose. However, the hollow part can also be a hose itself. This allows liquids, such as water, to be directed more precisely.

[0060] In one embodiment, the coupling nozzle is curved, at least in some areas. This allows for kink-free routing of a hose that passes through the hole in the base body. It also facilitates a kink-free transition into the hollow section.

[0061] In one embodiment, the insert has a plate-like base body with at least one further hole to which at least one pipe stub of the insert is formed, projecting into the space between the holes. This pipe stub serves as a coupling stub for another hollow part of the domestic refrigeration appliance. In addition to the advantages already mentioned above, this allows for improved coupling and routing of several, even different, hollow parts.

[0062] In one embodiment, the hollow part is a conduit for accommodating a cable. This allows electrical components to be safely installed and routed.

[0063] In one embodiment, the additional hole, viewed vertically from the base of the domestic refrigerator, is positioned higher than the first hole. This prevents, for example, damage to the electrical components in the event of a leak in the lower hole, through which liquid medium can flow.

[0064] In one embodiment, the hollow part is arranged on an inner side of a vertical side wall of the outer casing facing the cavity. This achieves an advantageous position and allows for short pipe runs to the components of the domestic refrigeration appliance to which water is to be supplied.

[0065] In one embodiment, spacers are arranged on the inside of the side wall, and the hollow part is mounted on these spacers. This allows for stable positioning while avoiding prolonged linear contact with the side wall. This offers advantages with regard to thermal insulation, as the hollow part can then be fully embedded in the thermal insulation material located in the space between the spacers.

[0066] In one embodiment, the domestic refrigeration unit has at least one hose that extends through the hole in the coupling nozzle and from there into the space between the units. The hose is routed upwards in this space, at least after the coupling nozzle, and into a receiving area between a top wall of the outer casing and an adjacent intermediate plate of the domestic refrigeration unit. This also results in a short routing path. Furthermore, existing space in this top area of ​​the domestic refrigeration unit is utilized to allow the hose to be routed, in particular, to a door of the unit. Especially if this door contains a water dispensing unit, the hose can be easily and quickly routed into the door via this top area and a hinge that attaches the door to the casing.In particular, no thermally insulating material is installed in the recording room.

[0067] In one embodiment, the intermediate plate has, in particular, channel-like recesses in which the hose is laid. This ensures that the hose is positioned with pinpoint accuracy.

[0068] In particular, a space is formed between the intermediate plate and a ceiling wall of an inner container of the household refrigeration appliance that follows downwards at a distance, in which thermally insulating material is contained.

[0069] The invention relates to a water supply device according to claim 1 for a liquid and / or ice dispensing unit of a household refrigeration appliance. The water supply device comprises a housing. Components for water supply are arranged in this housing. These components are part of the water supply device. In one embodiment, the housing has a housing cover. The housing also includes, in particular, a base module. The base module is attached to the housing cover by a non-destructively detachable connection. This design encloses the components of the water supply device and protects them in this context. This protects the components, in particular, from unwanted forces such as impacts or the like.Especially when the water supply unit is located in a compartment of the household refrigerator, collisions with food or storage containers, such as a storage tray or similar items, cannot damage or displace the water supply components. This effectively prevents unwanted leaks from the water supply components and / or a potentially large-scale water spillage. Furthermore, the housing's two-part construction allows for easy access to the internal components. For example, the base module and / or the housing cover can be easily removed, providing free access to the components inside.By directly connecting the housing cover to the base module, especially with a non-destructive connection, these components can also be easily separated and reassembled.

[0070] In one embodiment, the base module is formed as a single piece. This reduces the number of components. In particular, it is then very easy to remove only the base module as a single component when the housing needs to be opened. This also reduces the assembly and disassembly effort.

[0071] In one embodiment, the base module is coupled to the housing cover in a connected end position by at least one snap connection. This is another very advantageous embodiment because it ensures that the assembled end position is reliably and securely held. Unwanted slippage of the base module relative to the housing cover, or vice versa, can then be better prevented. Furthermore, a snap connection is a mechanically simple connection that can be reversibly released and re-established.

[0072] It is permanently highly functional and robust. It can easily withstand the forces that may occur. Furthermore, the snap connection allows for a very secure hold in the final position between the housing cover and the base module.

[0073] In one embodiment, the housing cover has at least one guide element. This guide element can be coupled to a counter-guide element located on the base module. This allows for a particularly simple, and especially linear, relative movement between the base module and the housing cover. This enables a jam-free and smooth connection between the housing cover and the base module. Especially when this guide device, with its guide element and counter-guide element, defines a linear mounting direction, mounting the base module to the housing cover is also very simple. In this case, when coupled, the base module can move in a straight line relative to the housing cover, and this movement is reliably guided to reach its final position. This results in a very simple assembly process.

[0074] In one embodiment, a guide element is formed on the outer surface of the housing cover. This makes the guide element exposed and thus easily visible to the user. This allows for very simple and precise coupling of the counter-guide element with the guide element. Furthermore, the relative movement between the counter-guide element and the coupled guide element can be observed virtually throughout the entire assembly process. The final assembled state is therefore easily identifiable visually. In particular, if a snap connection is provided to hold the final position between the base module and the housing cover, the final position is also clearly perceptible through haptic feedback.

[0075] In one embodiment, a guide element is designed as a guide skid. In particular, a step is formed in the side wall of the housing cover. This guides the linear assembly direction in a particularly advantageous manner. Such a step defines the path of movement of the counter-guide element on the guide element in at least two spatial directions.

[0076] In one embodiment, the guide element extends over at least 70 percent, and in particular at least 90 percent, of the length of a side wall. Specifically, the side wall is a longitudinal side wall of the housing cover. A longitudinal side wall is, in particular, a vertically oriented wall that is longer than any adjacent vertically oriented side walls of the housing cover. The housing cover is, in particular, cuboid in shape. With guide elements of this length, the entire assembly path between the coupled state and the final position between the base module and the housing cover is guided very smoothly. Furthermore, even in the corresponding final position, contact between the guide elements and the counter-guide element can be maintained. Therefore, the final position between the aforementioned components is also supported by this length of the guide element.

[0077] In one embodiment, the base module has a guide element. This guide element is designed to guide the water tank of the water supply system as it is moved towards the housing. In this embodiment, the guide element is integrated into the base module, meaning it is manufactured as a single piece. This simplifies the assembly and helps locate the final position of the water tank within the water supply system. This allows for very precise positioning of the water tank. This guided movement of the water tank is particularly advantageous when the assembly process also automatically connects a hose and / or nozzle of the water tank to a hose and / or nozzle in a unit of the water supply system adjacent to the water tank.This ensures that the water tank's final position is reached reliably and safely, and also automatically generates the necessary coupling process between the aforementioned connections. This allows for a precise connection at this interface, thus minimizing the risk of unwanted leaks at this interface.

[0078] In one embodiment, the guide element is designed as a guide tongue. This allows for a highly exposed and oriented position, enabling very simple and straightforward coupling with the water tank. Guiding the water tank during assembly is also improved. This design effectively prevents the water tank from tilting or slipping out of the coupled position with the guide tongue.

[0079] In one embodiment, the guide element is arranged to protrude from a side wall of the base module. This exposed position and orientation makes it particularly easy to couple the water tank and to guide the assembly movement safely into the final position.

[0080] In one embodiment, the guide element can be freely cantilevered. This further supports the advantages mentioned above.

[0081] In one embodiment, the base module includes a mounting plate. This mounting plate is designed for placing the water tank. It is oriented such that the water tank can be positioned laterally and directly adjacent to the housing of the water supply unit or to the housing of a freestanding assembly of the water supply unit. The mounting plate is preferably dimensioned to cover at least 90 percent of the surface area of ​​the water tank's base. This allows the water tank to be placed, particularly with its entire base resting on the mounting plate.

[0082] In one embodiment, the guide element is integrated into the mounting plate. Thus, the mounting plate and the guide element are formed as a single piece. In this embodiment, the guide element can project upwards above the top surface of the mounting plate. This design stabilizes the guide element through its integration into the mounting plate. In the event of an impact or other force, damage to the guide element is thus better prevented.

[0083] Furthermore, this design also prevents damage, such as scratches, to any additional components located externally to the water supply unit, on which the base module rests, during the installation of the water tank. This is because the mounting plate acts as an intermediary between this additional component, such as a shelf of the household refrigerator (e.g., a glass shelf), and the water tank.

[0084] Another aspect of the invention relates to a household refrigeration appliance with a water supply device according to claim 1.

[0085] A household refrigeration appliance is specifically designed for storing and preserving food. A household refrigeration appliance can be, for example, a refrigerator, a freezer, or a combination refrigerator-freezer. It can have an outer casing and an inner container arranged within it. In one embodiment, the inner container can define at least one storage compartment for food. Such a storage compartment can be, for example, a refrigerator compartment or a freezer compartment. Furthermore, a household refrigeration appliance can have at least one door that is movably attached to the appliance's body. This door can, for example, house a dispensing device for the liquid and / or ice dispenser of the household refrigeration appliance.

[0086] One aspect of the invention relates to a liquid and / or ice dispensing unit of a household refrigeration appliance. The liquid and / or ice dispensing unit comprises a water treatment device according to claim 1.

[0087] Exemplary embodiments of an independent aspect relating to a water supply device according to claim 1 are to be regarded as advantageous exemplary embodiments of the other independent aspects. The same applies to the independent aspects relating to a liquid and / or ice dispensing unit and / or to a household refrigeration appliance.

[0088] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth", "latitude", "height" indicate the positions and orientations given when the device or household appliance is used and positioned as intended.

[0089] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, can be used not only in the combinations specified, but also in other combinations or on their own, without departing from the scope of the invention according to claim 1. Thus, embodiments that are not explicitly shown and explained in the figures, but which can be derived from the explained embodiments by separate combinations of features and can be produced if they comply with the following claims, are also to be considered as encompassed and disclosed by the invention.

[0091] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0092] In Fig. 1 Figure 1 shows a perspective view of an embodiment of a household refrigeration appliance 1 according to claim 13. The household refrigeration appliance 1 is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator, a freezer, or a refrigerator-freezer combination. The household refrigeration appliance 1 has a housing 2, which can also be referred to as the body. The housing 2 has an outer casing 3. The outer casing also has, in particular, vertical side walls 3a and 3b. It also has a top wall, which is not shown here. Fig. 1 Figure 1 shows an intermediate plate 3c present in an exemplary embodiment. This intermediate plate 3c is arranged between the top wall of the outer casing 3 and a top wall of an inner container 4 of the domestic refrigeration appliance 1. This creates a receiving space between the top wall of the outer casing 3 and the intermediate plate 3c, in which components can be arranged. Thermally insulating material is arranged in the space between the intermediate plate 3c and the top wall of the inner container 4. In one exemplary embodiment, recesses 3d, 3e are formed on the upper surface of the intermediate plate 3c facing the top wall of the outer casing 3. In particular, these recesses 3d, 3e can be for at least one hose.

[0093] Furthermore, the housing 2 also has an inner container 4. The inner container 4 is separate from the outer housing 3. The inner container 4 is enclosed within the outer housing 3. The inner container 4, with its walls, defines at least one storage compartment 5 for food. The storage compartment 5 can be a refrigerator compartment. In another embodiment, the household refrigerator 1 can have a further storage compartment 6. This can be a freezer compartment.

[0094] Furthermore, the household refrigeration appliance 1 has at least one door 7. In the exemplary embodiment, two doors 7 and 8 are provided, which close off the front of the receiving compartment 5. It is also possible that further doors 9 and 10 are provided, which close off the front of the preferably existing additional receiving compartment 6.

[0095] The household refrigeration appliance 1 has a liquid and / or ice dispensing unit 11. This unit is designed to dispense liquids, such as beverages, and / or ice. As can be seen in the exemplary embodiment and in the further perspective in Fig. 2a As shown, this liquid and / or ice dispensing unit 11 has a dispensing device 12. In this exemplary embodiment, the dispensing device is arranged in the door 7. A recess 13 is preferably formed on an outer surface 7a of the door 7. A receiving container, such as a drinking glass, can be placed in this recess. Liquid is then dispensed by actuating the dispensing device 12.

[0096] As can be seen, the dispensing device 12 can be fluidly connected to a water supply unit 15 by means of at least one line 14. The water supply unit 15 according to claim 1 is arranged here in the receiving chamber 5. It is part of the liquid and / or ice dispensing unit 11. In another embodiment, the water supply unit 15 can be connected via a further line 16 to a further device 17 arranged in the receiving chamber 6. This allows, for example, the production and provision of very strongly chilled liquid or ice. Water that flows from the water supply unit 15 to the device 17 via this line 16 can then be very strongly chilled, and in particular frozen, in the receiving chamber 6, which is preferably designed here as a freezer compartment.In this context, in one embodiment, an ice tray, which may be part of the device 17, for example, can be filled with water from the water supply device 15, and then ice can be produced. In one embodiment, this ice can then also be dispensed via a specific compartment, for example a compartment 18, as shown in [reference]. Fig. 1 The unit shown can be removed. The device 17 can be an ice production device or an ice maker of the liquid and / or ice dispensing unit 11.

[0097] In Fig. 2a The household refrigerating appliance 1 according to claim 13 is shown from the side with the outer casing 3 removed and the inner container 4 shown transparently on this side wall so that the components, as described above, can be seen.

[0098] In Fig. 2b is, in a corresponding representation as in Fig. 2a , another embodiment of a household refrigeration appliance 1 according to claim 13 is shown. In contrast to Fig. 2a Here, the device 17 is arranged in the receiving chamber 5, specifically in an upper corner area. However, the device 17 is thermally insulated from the rest of the receiving chamber 5. In this embodiment, ice can, for example, be automatically dispensed from the device 17 to the dispensing unit 12 by means of an ice chute arranged in the household refrigerator 1.

[0099] In Fig. 3 This is an enlarged view of a section of Fig. 1 The figure shows the section in which the water supply device 15 according to claim 1 is arranged. A wall 19 of the inner container 4 is shown. The water supply device 15 according to claim 1 is arranged adjacent to this vertical wall 19. A partition 20, such as a shelf, is arranged below the water supply device 15. The water supply device 15 preferably comprises a subassembly 21. The subassembly 21 is equipped, in particular, with components such as at least one hose and / or at least one pump. It is therefore intended, in particular, for conveying or transferring liquid, especially water. The subassembly 21 comprises a housing 22. In one embodiment, this housing 22 has a housing cover 23. In another embodiment, this housing 22 has a base module 24.In particular, the partition wall 20 is located directly below the water supply unit 15. It can be removed separately from the water supply unit 15. This allows it to be easily cleaned independently of the water supply unit 15.

[0100] Furthermore, the water supply unit 15 includes a water tank 25. The water tank 25 is separate from the subassembly 21. It is therefore also located outside the housing 22. In the exemplary embodiment, the water tank 25 is arranged in its illustrated end position directly adjacent to and following the subassembly 21. It is positioned in front of the subassembly 21 in the depth direction (z-direction), particularly in the direction of the household refrigerator 1. The water tank 25 is designed to be removable without damage. It can therefore be removed and reinserted reversibly. In particular, it can thus be removed by a user and filled manually, for example at a tap.

[0101] For this purpose, it is arranged to be movable, particularly in a linear direction, here in the depth direction.

[0102] In Fig. 4 In a perspective drawing, the arrangement is according to Fig. 3 shown, whereby in Fig. 4 The water tank 25 has been removed. In this embodiment, a configuration of the base module 24 can be seen. The base module 24 has, in particular, a base unit 26. This unit defines the bottom boundary of the housing 22. This base unit 26 is also directly connected to the housing cover 23.

[0103] Furthermore, the base module 24 has a guide element 27. The guide element 27 is designed to guide the water tank 25 during assembly and disassembly. This facilitates the linear assembly direction of the water tank 25. This guide element 27 can be a freely cantilevered guide tongue. It can be integrally molded onto a side wall 28 of the base unit 26 and project from there.

[0104] In another embodiment, as described in Fig. 4 As shown, this base module 24 can have a support plate or a mounting plate 29. This is intended to ensure that the water tank 25 is in its final position, as shown in Fig. 3 As shown, it is positioned on top of this. This prevents components, such as the partition wall 20, from coming into direct contact with the water tank 25.

[0105] In the embodiment according to Fig. 4 The guide element 27 can also be formed integrally with the mounting plate 29. It is thus integrated into the mounting plate 29. In the vertical direction (y-direction), this guide element 27 preferably projects upwards beyond the top surface of the mounting plate 29.

[0106] The mounting plate 29 can have a raised stop 30 on its front side. This prevents the water tank 25 from sliding forward unintentionally in its final position, as shown in Fig. 3 It has been shown to be prevented.

[0107] Furthermore, this specific guidance scenario also makes it possible for a coupling nozzle of the water tank 25 to be automatically coupled to a coupling nozzle 31 of the sub-assembly 21 when the water tank 25 is attached to the final position.

[0108] The housing cover 23 is connected to the base module 24 by a detachable connection. As described in Fig. 5 As can be seen, the base module 24 can be separated from the housing cover 23. In one embodiment, this separation can be achieved through a relative movement, particularly a linear relative movement, as exemplified by the assembly direction P1. In another embodiment, a guide element 34 is formed on an outer surface 32 of a side wall 33 of the housing cover 23. The guide element 34 is integrated into this outer surface 32. The guide element 34 can be designed as a guide skid. This also means that it can, for example, be formed as a step in this outer surface 32. As shown in the embodiment, it can extend over at least 90 percent of the length of the side wall 33. Here, it extends over the entire length, which is measured in the width direction (x-direction).The side wall 33 here represents a longitudinal side wall of the housing cover 23. In particular, a counter-guide element 35 of the base module 24 can be coupled to this guide element 34, so that the relative movement between the housing cover 23 and the base module 24 is guided. Additionally or instead, a corresponding guide element can also be formed on the opposite longitudinal side wall of the housing cover 23. This can then be coupled to a counter-guide element 36 to guide the relative movement.

[0109] Preferably, the base module 24 is formed in one piece. It can, for example, be an injection-molded component. Fig. 5 The assembly direction P1 is shown, in which the base module 24 is to be moved when it is moved from the end position according to Fig. 4 to be removed and detached from the housing cover 23. If the base module 24 is to be reassembled, it is to be coupled to the housing cover 23 in the opposite direction to the assembly direction P1 and placed in the final position according to Fig. 4 to move. In particular, afterwards the water tank 25 can then be pushed on according to a mounting direction P2 perpendicular to it, until it reaches the in Fig. 3 has reached the final position shown.

[0110] In Fig. 6 In a perspective sectional view, the arrangement is as follows: Fig. 4 shown, whereby in Fig. 4 The section line VI-VI is shown.

[0111] As can be seen here, a snap connection 37 can be provided in one embodiment. This snap connection 37 allows, in particular, improved retention of the end position of the base module 24 with the housing cover 23. This effectively prevents unwanted slippage of the base module 24. Specifically, the snap connection 37 can be released by overcoming a force threshold when moving the base module 24 out of its end position. Therefore, in one embodiment, no additional release tool or similar device is required to release the snap connection 37.

[0112] It is particularly advantageous that the household refrigeration appliance 1 has an insert 38, as is the case in Fig. 7 shown in the assembled final position. The insert 38 can also be referred to as the backing part.

[0113] It is in an intermediate space 39 ( Fig. 1 ) arranged. This space 39 is formed between the outer casing 3 and the inner container 4. The space 39 is preferably filled with a thermally insulating material. The thermally insulating material can comprise insulating foam and / or vacuum insulation panels. As in Fig. 7 As can be seen, this wall 19 has an opening 19a. The insert 38 is arranged in the area of ​​this opening 19a. It extends with partial elements into the receiving space 5.

[0114] The insert 38 is preferably a one-piece component. It is made of plastic, in particular. It can be an injection-molded part. In this exemplary embodiment, the insert 38 is provided for direct coupling with the water supply unit 15. It is designed, in particular, so that the water supply unit 15 can be directly coupled to this insert 38. In particular, this coupling connection is designed such that the water supply unit 15 can be freely mounted on this insert 38. The water supply unit 15 can therefore also be attached to this insert 38 and then extends freely cantilevered into the receiving space 5. In this context, for example, Fig. 5 This self-supporting attachment, shown there in sub-assembly 21, on the insert 38. In particular, it is also shown in Fig. 4 A corresponding illustration is shown. Therefore, it is not necessary for the water supply unit 15 to be supported downwards. Rather, this coupling connection between the insert 38 and at least one specific component of the water supply unit 15 can absorb the corresponding weight and leverage forces.

[0115] Preferably, the insert 38 has a coupling device 40. This coupling device 40 is designed for direct coupling with a mating coupling device, such as that provided on the water supply unit 15. In particular, the coupling connection here is a purely mechanical coupling connection. In the exemplary embodiment, the coupling device 40 can have a coupling rail 41. Preferably, a first, in particular upper, coupling rail 41 and a second, in particular lower, coupling rail 42 are provided.

[0116] In one embodiment, these coupling rails 41 and 42 can have an L-shape in cross-section perpendicular to their longitudinal axes. The water supply device 15 can be directly arranged, in particular suspended, on these coupling rails 41 and 42.

[0117] In one embodiment, the coupling device 40 can also have at least one positioning dome 43. This is for inserting a dome receptacle 44, as described in Fig. 8 As shown, this positioning dome 43 can be a screw dome in one embodiment. This allows a screw connection to be provided at the location of the positioning dome and the inserted dome receptacle 44. The coupling device 40 is connected to a counter-coupling device 45, as shown in Fig. 8 shown, non-destructively detachable. This feedback device 45 can have feedback rails 46, as shown in Fig. 8 As shown. These counter-coupling rails 46 and 47 can engage in the preferably existing coupling rails 41 and 42, in particular by being hooked into them.

[0118] Furthermore, in Fig. 7 As can also be seen, the insert 38 has additional integrated channels 48, which are intended for connection to hoses for conveying media. This applies here to the two channels 48 with a more rounded cross-section. They are intended for two pumps 79, 80. In one embodiment, a domestic refrigeration appliance 1 may also have only one pump 79 or 80 for the liquid and / or ice dispensing unit 11. In this case, there are also channels 48 which, for example, have a more angular cross-section. These are arranged vertically above the more rounded channels 48. These more angular channels 48 are cable ducts. In particular, a cable duct and a channel 48 arranged below it with a more rounded cross-section always belong together. Cables for the respective pump 79, 80 can be laid in these cable ducts.

[0119] In Fig. 7 The base body 55 has a hole 55a, which belongs to one of the channels 48. A coupling spigot 48a is integrally formed on the back of the hole 55a. This coupling spigot 48a thus projects from the back of the base body 55 into the space 39. The coupling spigot 48a is formed integrally with the base body 55. The coupling spigot 48a allows coupling with a hollow component, such as a conduit for laying a separate hose or a hose itself. If two pumps 79, 80 are present, a second hole 55b may be provided in the base body 55. A coupling spigot 48b also terminates at this hole, extending from the back. A hole 55c may be formed in the base body 55 for a channel 48 designed as a cable duct. It may also be provided here that a coupling fitting 48c ends at the rear at hole 55c.In particular, the holes 55a and 55c for passing through a hose on the one hand and at least a cable on the other hand for one of the pumps 79, 80 are assigned to each other and are arranged offset from each other in the vertical direction.

[0120] A further hole 55d may also be formed in the base body 55. A coupling fitting 48d may also be molded onto this hole, ending at the rear. In particular, the coupling fittings 48a and 48b may have coupling structures to allow empty conduits or a hose to be directly connected to them.

[0121] The coupling nozzles 48a to 48d are also, viewed from the perspective of the space 39, in Fig. 2a and 2b to recognize. In Fig. 2a and 2bConduits 14a and 16a are shown schematically as examples. Hoses may be laid in these conduits. In particular, the conduits may only extend to the transition at the ceiling area. In the receiving area between the ceiling wall of the outer housing 3 and the intermediate plate 3c, the hoses are laid without conduits. Conduits are unnecessary there because they are not embedded in the thermal insulation material, which is particularly the case in the lateral gap 39. To allow the hoses and cables to be laid in this area even after the thermal insulation material has been installed, it is advantageous to use conduits that are laid before the thermal insulation material is installed.

[0122] As already mentioned in Fig. 7 As can be seen, the opening 19a has a threading area 49. This has a clear width 50. In particular, this clear width 50 is larger than a clear width 51 of an opening area 52 of the opening 19a.

[0123] As in Fig. 8 As can be seen, the water supply device 15 according to claim 1 has a support 53. The support 53 is directly coupled to the insert 38. The support 53 is only partially shown here, so that the insert 38 can be seen behind it. In particular, it is evident in Fig. 8 Only one basic body 54 of this support 53 is shown. The basic body 54 can be formed in a frame-like manner, as shown in Fig. 8 This is shown. This also allows hoses and cables to be routed through to insert 38.

[0124] In Fig. 9 is the representation of the components according to Fig. 7 shown. However, it is not yet shown here, unlike in Fig. 7 The figure does not depict the assembled final state of the insert 38. Rather, an intermediate assembly state is shown here. In one embodiment, the assembly process may involve bringing the provided insert 38 from a side of the wall 19 facing the gap 39 to the opening 19a. During the assembly process, it may be provided that the insert 38 has a base body 55, as also shown in Fig. 7 As shown, at least one retaining element 56 can be integrally formed on this base body 55. Preferably, two retaining elements 56 and 57 are integrally formed on it. The retaining elements 56 and 57 can preferably be elongated retaining rails 58 and 59. They project from the base body 55. This allows the retaining rails 58 and 59, which are preferably L-shaped in cross-section, to each form a receiving groove 60 and 61. According to the illustration in Fig. 7 In the final position of the insert 38, respective surface areas 62 and 63 of the wall 19 are inserted. These surface areas 62 and 63 define the opening 19a, specifically on the upper and lower sides. These surface areas 62 and 63 are thus inserted into the slot-like receiving grooves 60 and 61, thereby holding the insert 38 against the wall 19. In the subsequent assembly process, this insert 38 is further surrounded by the insulation material, in particular the insulating foam, which is inserted into the space 39, thus additionally stabilizing and fixing it in position.

[0125] The retaining rails 58 and 59 are oriented and arranged in the vertical direction such that their distance, in particular between the free edges 58a, 59a facing away from each other, is greater than the clear width 51. However, in an advantageous embodiment, this distance between the free edges 58a and 59a facing away from each other ( Fig. 7 ) smaller than the clear width 50 of the threading area 49 measured in this direction. This advantageously allows, as shown in Fig. 9 As shown, simple assembly is possible. Starting from the position in Fig. 9 The insert 38 can be positioned such that the retaining rails 58 and 59 are guided through the opening 19a in the threading area 49, so that the insert 38 then extends on both sides of the opening 19a. Preferably, the threading ends 58b and 59b of the retaining rails 58 and 59 are widened for this purpose. This facilitates the threading of the surface areas 62 and 63 into these receiving grooves 60 and 61.

[0126] Based on the one in Fig. 9 The intermediate assembly state reached can then be further changed by moving the insert 38 in the direction of arrow P3, as shown in Fig. 10 As shown, the insert 38 is already guided and brought into the end position with a linear movement, as then according to Fig. 7 has been achieved.

[0127] In Fig. 11 Figure 1 shows a perspective view of a cross-sectional view of an embodiment of a water supply device 15 according to claim 1. As can be seen in this view, a nozzle 64 of the water tank 25 is coupled to the nozzle 31 of the subassembly 21.

[0128] Furthermore, it can be seen that in one embodiment, a detection element 65 is arranged in the water tank 25. The detection element 65 can be a magnetic float. In an advantageous embodiment, its movement is guided by a guide device 66. This particularly facilitates linear movement in the vertical direction. This movement can be limited by a stop element 67. In particular, the stop element 67 is arranged below the maximum possible water level in the water tank 25 when viewed in the vertical direction. This means that the detection element 65 is only allowed to float up to this stop element 67.

[0129] This detection element 65 is, in particular, a component of a level detection device. This, in turn, is a component of the water supply device 15. A further component of this level detection device can be a sensor unit 68, as described in Fig. 12 This sensor unit 68 is arranged in particular in the sub-assembly 21, especially inside the housing 22.

[0130] In particular, the sensor unit 68 is permanently installed in it.

[0131] As can be seen in this context, only a single such sensor unit 68 is provided here. The sensor unit 68 can, for example, be a reed switch. It is arranged, particularly in the vertical direction, such that, in conjunction with the detection element 65, it detects a water level in the water tank 25 that is neither the maximum fill level nor the empty level of the water tank 25. Rather, an intermediate level can be directly detected as the fill level.

[0132] This is advantageous in that the empty fill level of the water tank 25 can also be determined indirectly with just a single sensor unit 68. In one embodiment, this is achieved by using a detection element 65, which is vertically movable on the water tank, to detect the contents of this sensor unit 68. Particularly when the fill level rises, for example during filling, this detection element 65 floats up with the water and thus moves vertically upwards. Once it has moved upwards far enough that the magnetic field triggers the reed switch, preferably located in the form of the sensor unit 68, and in particular closes it, this intermediate fill level is directly detected. It is also possible that a higher fill level is present in the water tank 25, for example, that the water tank 25 is completely full. In the present embodiment, this is not directly detected by the sensor unit 68.In particular, overflow is prevented because the water tank 25 is filled manually by a user.

[0133] When water is drawn from the water tank 25 during operation, the fill level drops. If this fill level falls below this intermediate level, the detection element 65 moves downwards from its upper position against the stop element 67. As the fill level decreases, the sensor unit 68 detects that the sensor element 65 has left its detection range. This means that at a specific lower fill level, other than the empty level, the sensor unit 68 detects that the detection element 65 has left its detection range. In this embodiment, this means that the reed switch opens again.Depending on the point in time at which the detection element 65 detects that the sensor unit 68 has left its detection range, the subsequent operating time and / or the subsequent flow rate, in particular from at least one pump of the water supply system 15, is then recorded. This can be done by corresponding sensors and / or a control unit. Specifically, this subsequent operating time and / or the subsequent flow rate is then compared with a predetermined reference operating time and / or a predetermined reference flow rate. The reference operating time is a period that describes how long it takes, after the detection of the sensor leaving its detection range, for the remaining amount of water in the water tank 25 to be pumped out, in particular by a pump.This reference operating time therefore characterizes the time it takes for the water in the water tank to empty completely, starting from the level present at which the detection element 65 registered that the water had left the detection range of the sensor unit 68. A corresponding reference flow rate can be used. This then characterizes the flow rate per unit of time required, in particular by at least one pump, to pump out the remaining water from the water tank 25 at the time the detection element 65 registered that the water had left the detection range of the sensor unit, until the water is completely pumped out of the water tank 25.

[0134] If, in this comparison, the further operating time corresponds to the reference operating time and / or the further delivery volume corresponds to the reference delivery volume, then the empty fill level and thus the empty water tank 25 can be determined very precisely indirectly.

[0135] In an advantageous embodiment, the detection element 65 is such that it is deliberately, and in particular only, partially immersed in the water. Specifically, the sensor unit 68 is positioned such that the detection area is left behind when the portion of the detection element 65 immersed in the water, with its lower end 65a (viewed from a height), is at a predetermined distance, for example, about one millimeter, from the bottom 25a, in particular from the inside of the bottom 25a, of the water tank 25, or, in another embodiment, is arranged to rest directly on this bottom 25a.Because then there is still a residual amount of water in the water tank 25 and, according to the scenario mentioned above, in an advantageous embodiment, the empty fill level can then be detected exactly when water is further pumped out of the water tank 25, and in particular, the time of reaching this empty fill level can be calculated very precisely.

[0136] In particular, the fill level is determined when the water level in water tank 25 is reduced, provided at least one of the pumps 79 or 80 is activated. If the switch is then opened, especially because the detection element 65 moves out of the detection range of the sensor unit 68, the fill level is determined. However, if an opening of the switch is detected and the pumps 79 and 80 are deactivated, it is also detected that the water tank 25 is being removed by a user. In this case, the fill level is not determined.

[0137] In Fig. 13 A partial view of the support 53 is shown in a perspective drawing. The support 53, preferably a single piece made of plastic, preferably as an injection-molded component, is a multifunctional or multi-component support. In particular, the sensor unit 68 is provided to be arranged on this support 53 in a way that allows for non-destructive removal. Preferably, the support 53 has an integrated, and thus integrally formed, holding unit 70 for the sensor unit 68. In one embodiment, the holding unit 70 has a first receiving web 71 and a second receiving web 72. These preferably each have a receptacle. These receptacles are formed here as support beds 73 and 74. These support beds 73 and 74 are formed here as ring sections. These freely cantilevered receiving webs 71 and 72 thus receive the sensor unit 68 in these support beds 73 and 74.The access ramps 71 and 72 can also be referred to as holding blocks.

[0138] In one embodiment, the holding unit 70 also has at least one snap element 98. This is a freely cantilevered tongue. It is also integrally formed on a support wall 69, similar to the receiving webs 71 and 72 in this embodiment. The support wall 69 is preferably integrally formed on the base body 54, and in particular, projecting from it. The snap element 98 is arranged separately from the receiving webs 71 and 72. A snap connection with the sensor unit 68 can be created using this snap element 98. In particular, the snap element 98 snaps onto a housing of the sensor unit 68.

[0139] In Fig. 14 is a partial section with the components according to Fig. 13 The sensor unit 68 is shown in its assembled final state. As can be seen here, the housing of the sensor unit 68 engages in the receptacles of the mounting brackets 71 and 72. Additionally, a snap connection with this housing is formed via the snap element 98.

[0140] Furthermore, in one embodiment, the holding unit 70 is provided with a stop wall 75. This stop wall 75 can be part of the support wall 69. The stop wall 75 is intended for the purpose of positioning a stop web 76 of the sensor unit 68 against it. This is particularly the case when the sensor unit 68 is arranged in its assembled end position on the support 53. As already described in Fig. 13 As can be seen, the supporting wall 69 is designed as an angled, in particular multi-angled, stiffening strip.

[0141] In Fig. 15 An exemplary embodiment of the support 53 is shown in a perspective view. In particular, the support 53 is designed as a one-piece component. Specifically, it is realized as an injection-molded component. In one exemplary embodiment, the support 53 has a retaining arm 77. Specifically, this retaining arm 77 projects from the base body 54. It is, in particular, cantilevered. The retaining arm 77 is designed to receive and thus also hold at least one hose 78 and / or at least one pump 79 and / or 80 of the water supply device 15. The retaining arm 77 preferably has a receptacle 81. This can be an upwardly open receptacle. In the illustrated exemplary embodiment, the hose 78 can thus be inserted into this receptacle from above. It is then securely and reliably positioned and can be easily assembled and disassembled due to this design. The nozzle 31 is also shown here.In particular, the receptacle 81 has engagement webs 82. These are integrally formed with the receptacle 81. They can engage in groove-like receptacles 83 of the hose coupling for the hose 78. This enables a particularly precise and stable mounting on the support arm 77.

[0142] The support 53 has a retaining structure 84. In one embodiment, this retaining structure 84 is a separate unit of the support 53 from the retaining arm 77. The retaining structure 84 is designed to receive and hold at least one hose 78 and / or 85. Alternatively, or in addition, the retaining structure 84 is also designed to receive or hold at least one pump 79 and / or 80. In the embodiment, two pumps 79 and 80 are part of the water supply system 15. However, there can also be more or fewer such pumps.

[0143] Preferably, the support 53 is designed to carry at least one hose, in particular all hoses, and / or at least one pump, in particular all pumps, of the water supply system 15. In particular, these components are received in corresponding receptacles, in particular suspended from them. The support 53 is thus designed such that the hoses and / or the pumps are suspended from the support 53. In particular, the pumps 79 and 80 can also be arranged to hang freely from this support 53. In this case, only the hoses can be inserted directly into corresponding receptacles from above and suspended from them, and the pumps 79 and 80 can be arranged to hang freely. They are then suspended from the support 53 only via the hoses.It is also possible, or alternatively, that the nozzles of pumps 79 and / or 80, to which hoses 78 and 85 connect, protrude into corresponding receptacles, and therefore the pumps themselves are also attached to or suspended from these components.

[0144] The support structure 84 has a water basin 86. The water basin 86 therefore represents an intermediate reservoir for water, which is pumped from the water tank 25 to an outlet of the water supply unit 15. Such an outlet can be, for example, an outlet 87 ( Fig. 2 ) be formed. In particular, if this outlet 87 is located lower than the water tank 25 (in terms of height), such a water basin 86 is especially advantageous as an intermediate reservoir. This is due to the hydrostatic pressure that arises from this difference in height. Thus, this hydrostatic pressure can be balanced by this water basin 86, preventing unwanted dripping of water from this outlet 87. In particular, this ensures that after filling, for example, the device 17, especially an ice mold, no further water drips from this outlet 87. Overflowing of the ice mold is thus easily avoided.

[0145] This water basin 86 is formed as a single piece with this support 53. It is integrated into this support 53. As in Fig. 15 As can also be seen, in one embodiment this water basin 86 can be arranged to project from the base body 54. In particular, this water basin 86 can be freely cantilevered from this base body 54. In one embodiment, the water basin 86 is designed as a shaft-like structure. It is particularly advantageous if an upwardly open receptacle 89 is formed in a boundary wall 88 of the water basin 86. A [missing text] can be inserted into this receptacle. Fig. 15 An additional water hose, not shown, can be attached.

[0146] In one embodiment, the support structure 84 has at least one retaining claw 90. Preferably, several such retaining claws 90, 91, 92, and 93 are provided. These retaining claws 90 to 93, the number and position of which are merely examples, extend freely cantilevered from the support structure 84, in particular from the water basin 86, and especially from the inner boundary wall 88. In particular, they extend in the direction of the preferably present and separate support arm 77. In particular, this support arm 53 provides a space 94 between the support structure 84 and the support arm 77. Components of the water supply system 15, such as hoses and / or pumps, can be arranged very compactly and in a space-saving manner in this space 94 and held very securely.

[0147] In Fig. 16 is the order according to Fig. 15 The diagram shows a top view, excluding the exemplary hoses 78, 85, and 95. The position and design of the retaining claws 90 to 93 are shown. They each preferably have claw openings 90a, 91a, 92a, and 93a. These openings are oriented upwards and are therefore open at the top. This allows for particularly easy mounting of additional components, such as hoses and pumps. Furthermore, these attached components can then be easily held by these retaining claws 90 to 93. In particular, they can then be held securely in these claw openings 90a to 93a by the corresponding weight force.

[0148] In Fig. 17 An exploded view shows an embodiment of the carrier 53 and a pre-assembly assembly or pre-assembly module 96. The pre-assembly module 96 includes, for example, the pumps 79 and 80 and at least some of the hoses 85, 78 and another hose 97. This hose 97 is preferably the one that will also be present in the assembled state. Fig. 18 It can be seen that it flows into water basin 86. It is particularly evident in photograph 89. The individual components of the support 53, as already explained in detail above, can be seen here in greater detail. Fig. 18 is the composite state of the in Fig. 17 The components shown are depicted. Bezugszeichenliste
