The invention relates to an insert (20A - 20E) for a detergent dosing unit (15) of a water-bearing household appliance (1), with a receiving section (25) which delimits a receiving volume (26A - 26E) in which a detergent can be received, the insert (20A - 20E) is set up to fill a cleaning agent storage chamber (17) of the cleaning agent dosing unit (15) at least in sections, so that the amount of cleaning agent that can be held in the cleaning agent storage chamber (17) is limited by the holding volume (26A - 26E).

Description

The following invention relates to an insert for a detergent dosing unit of a water-bearing household appliance, a modular system with several such inserts, a detergent dosing unit for a water-bearing household appliance and a water-bearing household appliance, in particular a domestic dishwasher, with such an insert, such a modular system and/or such detergent dosing unit.

A water-bearing household appliance, such as a dishwasher, includes a detergent dosing unit provided on a door of the water-bearing household appliance, which is suitable for releasing a detergent, for example in tablet, liquid or powder form, during a washing program. Such a detergent dosing unit includes a detergent storage chamber for receiving the detergent. A size or a volume of the cleaning agent storage chamber is usually dimensioned in such a way that the cleaning agent in the form of a tablet-shaped cleaning tab has enough space in it. In order to prevent the detergent tab from jamming when it is inserted into the detergent storage chamber, the detergent storage chamber is dimensioned significantly larger than the detergent tab itself. The detergent tab usually only occupies about 50% of the volume of the detergent storage chamber.

As a result, when using powder detergents or liquid detergents, the detergent storage chamber is often completely filled, so that there is too much detergent in the detergent storage chamber. The users of such a dishwasher are indeed advised in the instructions for use to use only about 20 to 25 g of detergent when using powder detergents or liquid detergents. However, since the instructions for use are usually not read, more than twice the amount of liquid or powder detergent actually required is usually filled into the detergent storage chamber. This dosing behavior is unecological and uneconomical.

Against this background, one object of the present invention is to provide an insert for a cleaning agent dosing unit of a water-bearing household appliance.

Accordingly, an insert for a detergent dosing unit of a water-bearing household appliance is proposed. The insert comprises an accommodation section which delimits an accommodation volume in which a detergent can be accommodated, the insert being set up to fill a detergent storage chamber of the detergent dosing unit at least in sections, so that the amount of detergent that can be accommodated in the detergent storage chamber is limited by the accommodation volume.

Due to the fact that the insert can be accommodated in the detergent storage chamber and the capacity of the insert limits the amount of detergent that can be accommodated, overdosing of the detergent can be reliably prevented. This is advantageous both ecologically and economically.

In particular, the amount of detergent that can be accommodated in the detergent storage chamber is exclusively limited by the intake volume. The insert is preferably an accessory, aftermarket part or retrofit part. In the present case, an “insert” should preferably be understood to mean a component that can be placed in the cleaning agent storage chamber and removed from it again. The insert is thus designed to be detachable from the cleaning agent storage chamber. The detergent dosing unit can also be referred to as a dosing unit or dosing device. The detergent dosing unit can be an add-on or an add-on system of a household dishwasher. However, the detergent dosing unit can also be a flushing tray of a domestic washing machine. The water-bearing domestic appliance can accordingly be a domestic dishwasher or a domestic washing machine, for example. Accordingly, the terms "water-bearing household appliance", "household dishwasher" and "household washing machine" can be interchanged at will.

The detergent dosing unit is set up in particular to automatically release the detergent during operation of the water-bearing household appliance, for example during rinsing operation. The detergent dosing unit preferably includes a cover that can be automatically opened at a specific point in time of a washing program in order to release the detergent. A control element or an actuator can be provided to open the cover.

The receiving section is preferably trough-shaped or trough-shaped and is suitable for receiving both a powdered and a liquid cleaning agent. In the present case, the fact that the receiving section “delimits” the receiving volume means in particular that the receiving section accommodates the receiving volume. The receiving volume is thus defined by a geometry of the receiving section. However, this does not rule out the receiving section being open at the top, for example, so that the cleaning agent can be filled into the receiving section. The receiving section can be closed at the top with the aid of the aforementioned cover.

The fact that the insert is set up to “fill at least in sections” the cleaning agent storage chamber of the cleaning agent dosing unit means in the present case in particular that the insert fills a volume defined by the cleaning agent storage chamber at least in sections. As soon as the insert is placed in the detergent storage chamber, the insert fills the volume delimited by the detergent storage chamber at least in sections, so that the detergent is no longer received directly in the detergent storage chamber but directly in the receiving section. The insert thus reduces the volume of the detergent storage chamber. Only the receiving volume of the receiving section thus defines the amount of detergent that can be received in the detergent dosing unit or in the detergent storage chamber.

According to one embodiment, the insert has an insertion section and a latching hook, the insertion section and the latching hook being set up to engage in a housing of the detergent dosing unit in order to positively connect the insert to the housing.

A form-fitting connection is created by two connection partners engaging or engaging behind one another. For example, recesses or openings are provided in the housing, into which the insertion section and the latching hook can engage. For example, to insert the insert into the detergent storage chamber, the insertion section is inserted into a first recess in the housing and the latching hook is then engaged or snapped into a second recess in the housing. Alternatively or additionally, the insert can also be connected to the housing in a frictionally or force-fitting manner.

According to a further embodiment, the insert also comprises a sealing element for fluid-tight sealing of the insert with respect to the detergent storage chamber.

The sealing element can be an O-ring or a sealing cord, for example. The sealing element prevents residues of detergent and other dirt from being deposited between the insert and the detergent storage chamber, which could lead to the formation of mold and unpleasant odours.

According to a further embodiment, leg sections for supporting the insert on a floor of the detergent storage chamber are integrally formed on the receiving section.

For example, two leg sections are provided. The leg sections are optional. The leg sections preferably extend out of the receiving section on the underside.

According to a further embodiment, the insert can be folded in order to change the storage volume, in particular to optionally increase or decrease it.

The holding volume of the holding section of the insert can thus be adapted with the aim of adapting to different types of detergent and/or degrees of soiling of the items to be washed, in order to be able to hold more or less detergent. “Foldable” or “foldable” means that individual sections, areas, elements or components of the insert can be moved relative to one another, in particular pivoted relative to one another, in order to change the storage volume, in particular to optionally increase or decrease it. For this purpose, the insert can be constructed in several parts. However, this is not mandatory. However, the insert can also be designed in one piece, in particular in one piece of material. In the present case, “in one piece” or “in one piece” means that the insert is not composed of different parts or components, but rather forms a coherent individual component. "One-piece material" means in the present case that the insert is made of the same material throughout. The mobility of individual sections, areas, elements or components of the insert relative to one another can be achieved, for example, with the aid of so-called solid joints, in particular with the aid of so-called film hinges. In the present case, a “flexible joint” is to be understood as an area of a component, for example the insert, which allows a relative movement between two rigid body areas by bending. A flexure joint can be realized, for example, by thinning out, constricting or constricting the material. In the present case, a film hinge is to be seen as a concrete embodiment of a solid joint. For example, a film hinge can be realized by a thin plastic film that can be provided between two thick-walled or solid areas or sections of the insert.

According to a further embodiment, the receiving section has a movable base in order to change the receiving volume, in particular to optionally increase or decrease it.

For example, the floor can be slidable. Instead of the floor, however, any other sections, areas, elements or Components of the depositor can be designed to be movable. It can thus be realized with only one insert several differing recording volumes. Even if the insert has the movable base, the insert can be designed in one piece, in particular in one piece of material. For this purpose, the floor can be made of an elastically deformable material, for example.

According to a further embodiment, the insert is a one-piece plastic component, in particular a one-piece material component.

The insert is preferably a plastic injection molded component. As a result, the insert can be produced inexpensively in large numbers. Examples of suitable plastic materials are polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), polyetheretherketone (PEEK), thermoplastic elastomers (TPE), in particular thermoplastic polyurethanes (TPU), or other suitable ones thermoplastics for use. A combination of different materials can also be provided. For this purpose, the insert can also be manufactured from different plastic materials in a multi-component plastic injection molding process, for example. The plastic material used can be fiber-reinforced, in particular synthetic fiber-reinforced.

According to a further embodiment, the insert has a cone-shaped and/or wedge-shaped geometry at least in sections.

As a result, when the insert is placed in the detergent storage chamber, the insert can be jammed in the detergent storage chamber in order to connect it to the detergent storage chamber in a non-positive or frictional manner. The insert can be resiliently deformed at least in sections. However, the insert can be removed from the detergent storage chamber again without tools.

Furthermore, a construction kit with a number of such inserts is proposed, with the number of inserts differing from one another in their capacity.

In particular, this means that the depositors differ from one another. The receiving volumes of the inserts that differ from one another are in particular of different sizes. For example, the modular system includes three variants of the insert. However, the number of variants is fundamentally arbitrary. For example, a first insert is provided, which is a so-called eco insert with a particularly small volume for accommodating the cleaning agent. The volume of the receiving area of the first insert can, for example, hold 15 g of detergent. The user saves up to 70% of the detergent compared to an application without a first insert. This corresponds to 35 g. This dosage is sufficient for light and medium soiling to achieve a very good cleaning result with optimized use of detergent. Furthermore, the kit can include a second insert, which can also be referred to as a standard insert. For example, 25 g of cleaning agent can be accommodated in the capacity of the second insert. The user can save up to 50% of the detergent compared to an application without a second insert. This corresponds to about 25 g. Furthermore, the kit can include a third insert. The third depositor is a so-called heavy-duty depositor. The capacity of the third insert can hold up to 35 g of detergent. The user can save up to 30% of the detergent compared to an application without the third insert. This corresponds to about 15 g. Nevertheless, the dosage is sufficient for even the heaviest soiling.

According to one embodiment, the multiple inserts are made of different materials.

The materials can only differ from one another in terms of their color, for example. Alternatively, different of the aforementioned plastic materials can also be used for the inserts, which differ from one another, for example, in terms of their deformability. As a result, the inserts are easily distinguishable from one another.

According to a further embodiment, the plurality of inserts differ from one another visually and/or haptically.

The visual distinction can be achieved, for example, by color coding. For example, the color green is chosen for the eco insert, the color blue for the standard insert and the color red for the heavy-duty insert. The haptic distinguishability can be achieved by the different inserts having different characteristic surface structures, for example. A haptic distinguishability can also be achieved by using different elastic plastic materials.

Furthermore, a detergent dosing unit for a water-bearing household appliance with such an insert and/or such a modular system is proposed.

The detergent dosing unit is preferably provided on the inside of a door of the water-bearing household appliance. The detergent dosing unit includes a lid that can be opened or moved, with the help of which the receiving section of the insert can be released, so that the detergent can be released into a washing compartment of the water-bearing household appliance.

According to one embodiment, the insert or one of the inserts of the modular system is connected to a housing of the detergent dosing unit in a form-fitting and/or friction-fitting manner.

This enables easy assembly and disassembly of the insert. The insert can be fitted to and removed from the detergent dosing unit without the use of tools.

According to a further embodiment, the housing has recesses in which the insert engages in a form-fitting manner.

For example, two such recesses are seen. The insert preferably has an insertion section, as mentioned above, which can be inserted into a first of the recesses. A latching hook of the insert, as mentioned above, then snaps into a second recess of the housing in order to positively connect the insert to the housing.

In addition, a water-carrying household appliance, in particular a household dishwasher, with such an insert, such a modular system and/or such a detergent dosing unit is proposed.

The water-bearing household appliance can also be a household washing machine, for example. However, the water-bearing household appliance can in principle be any water-bearing household appliance.

Further possible implementations of the insert, the modular system, the cleaning agent dosing unit and/or the water-conducting household appliance also include combinations of features or embodiments described above or below with regard to the exemplary embodiments that are not explicitly mentioned. The person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the insert, the modular system, the cleaning agent dosing unit and/or the water-bearing household appliance.

Further advantageous configurations and aspects of the insert, the modular system, the detergent dosing unit and/or the water-conducting household appliance are the subject matter of the dependent claims and the exemplary embodiments of the insert, the modular system, the detergent dosing unit and/or the water-conducting household appliance described below. The insert, the modular system, the cleaning agent dosing unit and/or the water-bearing household appliance are explained in more detail below on the basis of preferred embodiments with reference to the enclosed figures.

• 4 shows a schematic view of an embodiment of an insert for the feed system according to FIG 2 .

Elements that are the same or have the same function have been provided with the same reference symbols in the figures, unless otherwise stated.

the 1 shows a schematic perspective view of an embodiment of a water-bearing household appliance 1. The water-bearing household appliance 1 can be a household dishwasher or a household washing machine. In the following, however, it is assumed that the water-bearing domestic appliance 1 is a domestic dishwasher. The water-bearing domestic appliance 1 is therefore referred to below as a domestic dishwasher.

The domestic dishwasher 1 includes a washing compartment 2, which can be closed by a door 3, which is in particular watertight. For this purpose, a sealing device can be provided between the door 3 and the washing container 2 . The washing compartment 2 is preferably cuboid. The washing compartment 2 can be arranged in a housing of the domestic dishwasher 1 . The washing compartment 2 and the door 3 can form a washing chamber 4 for washing items to be washed.

Door 3 is in the 1 shown in their open position. The door 3 can be closed or opened by pivoting about a pivot axis 5 provided at a lower end of the door 3 . With the help of the door 3, a loading opening 6 of the washing compartment 2 can be closed or opened. The rinsing tank 2 has a floor 7, a ceiling 8 arranged opposite the floor 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The bottom 7, the top 8, the rear wall 9 and the side walls 10, 11 can be made from a stainless steel sheet, for example. Alternatively, for example, the bottom 7 can be made of a plastic material.

The household dishwasher 1 also has at least one washware holder 12 to 14 . Preferably, several, for example three, washware holders 12 to 14 can be provided, with washware holder 12 being a lower washware holder or a lower rack, washware holder 13 being an upper washware holder or an upper rack and washware holder 14 being a cutlery drawer. As the 1 further shows that the washing items receptacles 12 to 14 are arranged one above the other in the washing compartment 2 . Each washware holder 12 to 14 can be moved either into or out of the washing compartment 2 . In particular, each washware receptacle 12 to 14 can be pushed or moved into the washing compartment 2 in an insertion direction E and pulled out or moved out of the washing compartment 2 in an extension direction A counter to the insertion direction E.

the 2 shows a schematic sectional view of an embodiment of a dosing unit or detergent dosing unit 15 for the domestic dishwasher 1. The detergent dosing unit 15 can be an addition or an addition system of the domestic dishwasher 1. However, the detergent dosing unit 15 can also be a flushing tray of a domestic washing machine.

The detergent dosing unit 15 is suitable for automatically releasing a detergent, for example in liquid form, in tablet form, in particular a detergent tab, or in powder form during a wash program of the household dishwasher 1, so that it dissolves in the water supplied in order to Washware (not shown) to clean.

The detergent dosing unit 15 is provided on the inside of the door 3 . “Inside” means that the cleaning agent dosing unit 15 is arranged facing the washing compartment 4 . The detergent dosing unit 15 can protrude into the washing compartment 4 at least in sections. The detergent dosing unit 15 is preferably integrated into the door 3 . This means that the cleaning agent dosing unit 15 can be arranged at least in sections inside the door 3 . The detergent dosing unit 15 is placed at an upper edge of the door 3 . The cleaning agent dosing unit 15 is preferably placed centrally with respect to the side walls 10 , 11 .

The detergent dosing unit 15 includes a housing 16. The housing 16 can be a plastic component, in particular a plastic injection molded component. The housing 16 is fixed to the door 3 . Formed on or in the housing 16 is a detergent chamber or storage chamber 17 for receiving the aforementioned detergent. The detergent storage chamber 17 can also be referred to as a detergent compartment.

The detergent storage chamber 17 can be closed with the aid of a cover 18 . The lid 18 can be opened automatically at a predetermined time during a washing program. For this purpose, the cover 18 can be pivoted on the housing 16 . However, the cover 18 can also be opened and closed in that it performs a sliding movement relative to the housing 16, as is shown in FIG 2 is indicated with the help of a double arrow 19.

The cover 18 may be suitable for the cleaner storage chamber 17 to be sealed in a fluid-tight manner, so that in a closed state of the cover 18, as in FIG 2 shown, no liquid, such as water, can penetrate into the cleaner storage chamber 17 . A sealing element, for example in the form of a silicone seal or a sealing cord, can be provided for this purpose. Furthermore, the seal can also prevent liquid cleaning agent from escaping from the cleaning agent storage chamber 17 .

A size or a volume of the detergent storage chamber 17 is preferably dimensioned in such a way that there is enough space for a detergent tab. In order to prevent the detergent tab from jamming when it is inserted into the detergent storage chamber 17, the detergent storage chamber 17 must be dimensioned significantly larger than the detergent tab, so that only about 50% of the volume of the detergent storage chamber 17 is occupied by the detergent tab.

When using powder detergents or liquid detergents, users often fill the detergent storage chamber 17 almost full, so that there are approximately 50 g of detergent in the detergent storage chamber 17 . The instructions for use suggest that users only use around 20 to 25 g of detergent when using powder detergents or liquid detergents. However, since the instructions for use are usually not read, more than twice the amount of detergent actually required is usually filled into the detergent storage chamber 17 . This dosing ver holding is unecological and uneconomical. This needs to be improved.

In order to be able to control the dosing behavior and to prevent more than the actually required amount of detergent being dosed, an insert 20A that can be retrofitted is provided, which ensures that the amount of detergent in the detergent reservoir 17 does not exceed the amount required for cleaning the items to be washed can. The insert 20A can also be referred to as an insert, detergent dosage optimizer or "detergent dosage optimizer".

The insert 20A is preferably a plastic component, in particular a plastic injection molded component. Examples of suitable plastic materials are polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), polyetheretherketone (PEEK), thermoplastic elastomers (TPE), in particular thermoplastic polyurethanes (TPU), or other suitable ones thermoplastics for use. The plastic material used can be fiber-reinforced, in particular synthetic fiber-reinforced.

The insert 20A can be a one-piece component, in particular a one-piece material component. "In one piece" or "in one piece" means that the insert 20A is not composed of different components, but is formed as a unit. “One-piece material” means that the insert 20A is made of the same material throughout. Alternatively, however, the insert 20A can also be composed of different parts or components.

The insert 20A can be installed by a user in or on the existing detergent metering unit 15 or in or on the detergent storage chamber 17 without tools and can be removed from it. The insert 20A can be fixed in the detergent storage chamber 17, for example, via a snap hook mechanism, via a frictional connection or the like. If a frictional connection is provided, the insert 20A can have a wedge-shaped and/or conical geometry at least in sections.

For example, the insert 20A includes an insertion section 21 that is inserted into a corresponding recess 22 of the housing 16 . Furthermore, the insert 20A has a snap hook or latching hook 23 which is arranged opposite the insertion section 21 and engages in a corresponding recess 24 of the housing 16 . The insert 20A can thus be connected to the housing 16 in a form-fitting manner. A form-fitting connection is created by two connection partners engaging or engaging behind one another.

To accommodate the cleaner, the depositor 20A comprises a trough-shaped, trough-shaped or trough-shaped receiving section 25 which, in the orientation of the 2 is open at the top. The accommodating portion 25 encloses an accommodating volume 26A for accommodating the cleaner. The user fills the cleaner into the receiving section 25 . The accommodating volume 26A of the accommodating section 25 is smaller compared to a volume of the detergent storage chamber 17 . The holding volume 26A controls the amount of cleanser to be added by the user. With the help of the insert 20A, resources can be saved by optimally setting the dosage of the cleaning agent if powder cleaning agents or liquid cleaning agents are used.

The insertion section 21 and the latching hook 23 are molded onto the receiving section 25 . In the orientation of 2 On the underside, two leg sections 27 , 28 extend out of the receiving section 25 and are supported on a floor 29 of the detergent storage chamber 17 . The leg sections 27, 28 are optional.

Furthermore, the insert 20A is sealed against the detergent storage chamber 17 with the aid of a circumferential sealing element 30, for example in the form of an O-ring. This prevents residues of cleaning agent and other dirt from being able to deposit between the insert 20A and the cleaning agent storage chamber 17, which could lead to the formation of mold and unpleasant odors.

The Indian 2 The insert 20A shown represents a basic version in which the receiving section 25 is designed in such a way that, for example, 25 g of cleaning agent can be accommodated in this. This amount of detergent is 2 g more than the maximum used in a label program. This ensures both label conformity and a very good cleaning result. In comparison to the usual dosing behavior as explained above, the user thus saves 25 g of cleaning agent. This roughly corresponds to a saving of 50%.

In order to be able to cover different types of detergent and/or degrees of soiling of the items to be washed, a construction kit or set (not shown) with different inserts 20A can be provided, which differ from one another in terms of their capacity 26A. These different inserts 20A can, for example, be marked in color or be made of differently colored plastic materials. Different colors can be assigned to different receiving volumes 26A.

the 3 shows a schematic view of an embodiment of a set or construction kit 31 as mentioned above, which has several inserts 20B, 20C, 20D, which differ from one another with regard to their receiving volumes 26B, 26C, 26D. For example, the inserts 20B, 20C, 20D have different receiving sections 25 with different geometries for this purpose. The construction kit 31 includes, for example, three variants of the insert 20B, 20C, 20D. However, the number of variants of the insert 20B, 20C, 20D is basically arbitrary.

For example, a first insert 20B is provided, which is what is known as an eco insert. The holding volume 26B of the holding section 25 of the first insert 20B can hold 15 g of cleaning agent, for example. The user saves up to 70% of the detergent compared to an application without the first insert 20B. This corresponds to 35 g. This dosage is sufficient for light and medium soiling to achieve a very good cleaning result with optimized use of detergent.

Furthermore, the construction kit 31 can include a second insert 20C, which can also be referred to as a standard insert. 25 g of cleaning agent can be accommodated in the accommodation volume 26C of the second insert 20C. The user can save up to 50% of the detergent compared to an application without a second insert 20C. This corresponds to about 25 g. The second insert 20C can be identical to the insert 20A.

The kit 31 can also include a third insert 20D. The third insert 20D is a so-called heavy-duty insert. The holding volume 26D of the third insert 20D can hold up to 35 g of cleaning agent. The user can save up to 30% of the detergent compared to an application without a third insert 20D. This corresponds to about 15 g. Nevertheless, the dosage is sufficient for even the heaviest soiling.

The inserts 20B, 20C, 20D can be designed in different colors for better differentiation and as a visually appealing design. For example, the color green can be used for the first insert 20B, the color blue for the second insert 20C and the color red for the third insert 20D. However, the choice of color is basically arbitrary. Different materials and/or surface structures can also be used in order to make the inserts 20B, 20C, 20D distinguishable.

the 4 shows a schematic view of a further embodiment of an insert 20E. In contrast to the embodiments of the insert 20A, 20B, 20C, 20D, the insert 20E is designed to be foldable or collapsible, so that a receiving volume 26E of the receiving section 25 of the insert 20E can be adapted with the aim of adapting to different types of detergent and/or degrees of soiling of the items to be washed leaves in order to be able to absorb more or less cleaning agent.

In this context, “foldable” or “foldable” means that individual sections, areas, elements or components of the insert 20E can be moved relative to one another in order to change the receiving volume 26E, in particular to optionally increase or decrease it. For example, the receiving section 25 can have a movable floor 32 . The bottom 32 can in the orientation of 4 be shifted up and down, as indicated by a double arrow 33.

Possible different positions of the floor 32 and thus different recording volumes 26E are in FIG 4 shown with dash-dotted lines and provided with the reference symbols 32', 32". Instead of the base 32, however, other sections, areas, elements or components of the insert 20E can also be designed to be movable. Thus, with just one insert 20E, several different receiving volumes can be used 26E can be realized.

The insert 20E can be constructed in several parts. For example, the floor 32 is a separate component from the insert 20E. However, the insert 20E can also be designed in one piece, in particular in one piece of material, if it is designed to be foldable or collapsible. In this case, for example, the base 32 is formed in one piece, in particular in one piece of material, with the insert 20E. The bottom 32 can be made of an elastically deformable material, for example.

With all embodiments of the insert 20A, 20B, 20C, 20D, 20E it is possible to optimize the amount of cleaning agent to be taken up. Wastage of up to 50% of the detergent per wash cycle can be avoided. This is advantageous in terms of protecting the environment and resources.

Although the present invention has been described using exemplary embodiments, it can be modified in many ways.
