- US 2019/0104914 A1 describes an addition device for a dishwasher as mentioned above.
- the adding device comprises a receiving part for receiving a cleaning agent and a cover which can be moved from an open state to a closed state and vice versa. After the receiving part has been filled with the cleaning agent, the lid is moved from the open state to the closed state. To release the cleaning agent, the lid opens while the dishwasher is in operation.
- a household dishwasher with a washing compartment, which encloses a washing chamber of the household dishwasher, and an adding device for adding a cleaning agent to the washing chamber.
- the dispensing device has a receiving part with a receiving area for receiving the cleaning agent, a cover for closing the receiving area and a sealing arrangement arranged at least in sections between the receiving part and the cover, the sealing arrangement having a first sealing lip and a second sealing lip that differs from the first sealing lip comprises, wherein the sealing arrangement runs completely around the receiving area, wherein the first sealing lip only partially runs around the receiving area, and wherein the second sealing lip also only partially runs around the receiving area. Due to the two different sealing lips, the sealing arrangement does not have a closed but an interrupted sealing contour, whereby a reliable function of the dispensing device can be achieved with low operating forces of the lid and at the same time more secure sealing.
- the rinsing container is preferably cuboid or box-shaped.
- the rinsing space is provided inside the rinsing container.
- the rinsing space can be delimited or enclosed by the rinsing compartment and a door attached to the rinsing compartment.
- the washing compartment and possibly the door thus determine the boundaries or the spatial extent of the washing area.

- the dispensing device is set up to receive and dispense the cleaning agent in tablet form, powder form or as a liquid.
- the addition device can be filled manually with the cleaning agent.
- the dispensing device then automatically releases the cleaning agent during a washing process of the household dishwasher, so that the cleaning agent can dissolve in the washing liquor and/or fresh water in the washing chamber in order to clean items to be washed in the washing chamber.
- the receiving part is preferably attached to the aforementioned door. However, the receiving part can also be attached directly to the washing compartment, for example on a side wall of the washing compartment.
- the receiving part is preferably a plastic component, in particular a plastic injection molded component.
- the receiving area is formed onto the receiving part.
- the receiving area is preferably trough-shaped or trough-shaped and can receive the cleaning agent.
- the receiving area can be closed or opened with the help of the cover and can thus be moved from an open state to a closed state and vice versa.

- TPE thermoplastic elastomer
- TPU thermoplastic polyurethane
- the material used for the sealing arrangement can be foamed.
- the material can be compressible or compressible.
- first sealing lip and the second sealing lip are two sections or areas of the sealing arrangement which are in particular spatially separate from one another and which preferably do not touch one another and/or are not in contact with one another be in contact. However, this does not preclude the sealing lips from being connected to one another with the aid of a connecting section.
- the sealing arrangement thus has in particular no closed sealing geometry or sealing contour, but rather an open or interrupted sealing geometry or sealing contour.
- a “sealing geometry” or “sealing contour” is to be understood here as a geometry or contour, ie an outline, of the sealing arrangement with which the sealing arrangement rests against the cover in the closed state.
- the sealing arrangement itself together with the two sealing lips, completely surrounds the receiving area. That is, the receiving area is arranged within the sealing arrangement, which completely surrounds or encloses the receiving area.
- the first sealing lip and the second sealing lip each run only or only partially around the receiving area. "Only” or “only” means in this context that the respective sealing lip does not completely encircle the receiving area.
- the first sealing lip and the second sealing lip each have an open sealing geometry or sealing contour rather than a closed one.
- the first sealing lip and the second sealing lip are arranged in such a way that they together form the sealing arrangement that completely surrounds the receiving area.

For example, the door has a thickness of a few centimeters along the depth direction.
- the dispensing device in particular the receiving area with the lid, protrudes partially over the door and into the washing compartment.
- a first overlapping area is preferably provided, in which the first sealing lip and the second sealing lip overlap, and a second overlapping area, in which the first sealing lip and the second sealing lip also overlap.
- overlap or “cover” means here that the first sealing lip and the second sealing lip are placed on top of one another or cover one another, viewed along the transverse direction.
- the fact that the overlapping area “can be arranged variably” means in particular that the overlapping area, viewed along the vertical direction, can be placed or arranged as desired.
- the first sealing lip is wider than the second sealing lip when viewed in the transverse direction.
- the first sealing lip can project beyond the second sealing lip on both sides.
- the first sealing lip covers the second sealing lip viewed along the vertical direction.
- the first sealing lip covers the second sealing lip in a roof-like manner, viewed along a vertical direction.
- the result of this is that liquid impinging on the first sealing lip, in particular washing liquor and/or fresh water, is guided around the second sealing lip. This reliably prevents liquid from penetrating into the receiving area.
- the vertical direction is assigned to the door or the adding device itself.
- the second sealing lip is arranged at least in sections within the first sealing lip, viewed along the transverse direction.
- first sealing lip preferably encloses or encloses the second sealing lip viewed along the transverse direction.
- the second sealing lip can protrude beyond the second sealing lip or protrude from it.

- the two first leg sections of the sealing lips overlap in the previously mentioned first overlapping area. Accordingly, the two second leg sections of the sealing lips overlap in the second overlapping area.
- a gap in particular an air gap, is provided at least in sections between the first sealing lip and the second sealing lip.
- the first sealing lip, the second sealing lip and the gap together form a labyrinth seal of the sealing arrangement.
- a "labyrinth seal” or “gap seal” is to be understood here as a non-contact seal in which the sealing lips do not touch one another and are therefore not in contact with one another.
- the sealing effect of the labyrinth seal is based on a Extending a flow path of a fluid, for example washing-up liquid and/or fresh water or a liquid cleaning agent, through the gap to be sealed, whereby the flow resistance for the fluid entering or exiting the adding device is significantly increased.
- the lengthening of the flow path is achieved by the two sealing lips intermeshing or intermeshing, as explained above. This interlocking of the two sealing lips is realized in particular only at the previously mentioned overlapping areas.
- the first sealing lip has a U-shaped geometry, with the second sealing lip also having a U-shaped geometry, and with the first sealing lip and the second sealing lip being arranged in such a way that the U-shaped geometries are in opposite directions and at least in sections are arranged one inside the other.
- the respective U-shaped geometry is formed with the aid of the base section and the leg sections arranged transversely to the base section.
- the two U-shaped geometries of the sealing lips are arranged in such a way that one of the U-shaped geometries is arranged upside down, so that the two U-shaped geometries are arranged one inside the other or crossed, at least in sections.
- "Opposite" in this context means in particular that one of the U-shaped geometries is reversed or placed upside down compared to the other U-shaped geometry.
- the cover is mounted on the receiving part in such a way that the dispensing device can be brought from a closed state to an open state and vice versa, the sealing arrangement being pressed between the receiving part and the cover in the closed state.
- the cover can, for example, be mounted on the receiving part such that it can pivot about an axis of rotation. Alternatively, the cover can be mounted in a linearly displaceable manner on the receiving part.
- “pressed” is to be understood to mean that the sealing arrangement is reversibly deformed in the closed state compared to the open state.
- the sealing arrangement has a connecting section, the first sealing lip being connected to the second sealing lip in one piece, in particular in one piece of material, simply with the aid of the connecting section.
- In one piece or “in one piece” means that the sealing lips and the connecting section form a common component and are not composed of different components.
- One-piece material means in particular that the sealing arrangement is made of the same material throughout.
- the sealing arrangement can be a plastic component, in particular a plastic injection molded component.
- the sealing arrangement can be molded onto the receiving part, for example with the aid of a multi-component injection molding process.
- the domestic dishwasher comprises a door attached to the washing compartment, with the addition device being attached to the door facing the washing chamber.
- the door can be mounted on the washing compartment so that it can pivot about a pivot axis.

- the adding device 15 also includes a sealing arrangement 31 for sealing the cover 21 in relation to the receiving part 23.
- a partial sectional view of the sealing arrangement 31 according to the section line IV-IV of FIG. 3 is shown in FIG.
- the sealing arrangement 31 is made of a flexible material such as silicone, rubber, polyurethane, a thermoplastic elastomer (TPE), in particular a thermoplastic polyurethane (TPU).
- TPE thermoplastic elastomer
- TPU thermoplastic polyurethane
- the material used for the sealing arrangement 31 can be foamed.
- the material can be compressible or compressible.
- the sealing arrangement 31 has a first sealing lip 32 and a second sealing lip 33 .
- the sealing lips 32, 33 can be connected to one another by means of a connecting section 34 (FIG. 4).
- the connecting section 34 can bear against the flange 26 or be connected to it.
- the first sealing lip 32 differs from the second sealing lip 33.
- “different” is to be understood to the effect that the two sealing lips 32, 33 are two separate areas or sections of the sealing arrangement 31. This means that the first sealing lip 32 and the second sealing lip 33 in particular do not touch or contact one another.
- the sealing lips 32, 33 are connected to one another exclusively with the aid of the connecting section 34. This results in an interrupted or open sealing geometry or sealing contour of the sealing arrangement 31.
- the sealing arrangement 31 can be a one-piece component, in particular a one-piece material component. "In one piece” or “in one piece” means that the sealing lips 32, 33 and the connecting section 34 form a common component and are not composed of different components. "One-piece material” means that the sealing arrangement 31 is made of the same material throughout.
- the sealing arrangement 31 is a plastic component, in particular a plastic injection molded component.
- the sealing arrangement 31 can be molded directly onto the receiving part 23, for example with the aid of a multi-component injection molding process.
- the first sealing lip 32 runs in the x-direction x along the upper edge 27 and extends partially in the y-direction y along the side edges 29, 30.
- the first sealing lip 32 therefore does not run completely around the receiving area 24 and does not enclose it either complete.
- the first sealing lip 32 thus has a circumferentially open sealing geometry or sealing contour.
- the second sealing lip 33 runs in the x-direction x along the lower edge 28 and partially extends in the y-direction y along the side edges 29, 30.
- the second sealing lip 33 therefore also does not run completely around the receiving area 24 and encloses it neither.
- the second sealing lip 33 thus also has a circumferentially open sealing geometry or sealing contour.
- the first sealing lip 32 and the second sealing lip 33 overlap in the area of the two side edges 29, 30 in a first overlapping area 35 and in a second overlapping area 36 along the y-direction y. Viewed along the x-direction x, the second sealing lip 33 is arranged inside the first sealing lip 32 .
- the first sealing lip 32 comprises a base section 37 running along the x-direction x and two leg sections 38, 39 provided at the ends of the base section 37, which are oriented transversely, in particular perpendicularly, to the base section 37 and run along the y-direction y.
- a first leg portion 38 and a second leg portion 39 are provided.
- the second sealing lip 33 also includes a base section 40 running along the x-direction x and two leg sections 41, 42 provided at the ends of the base section 40, which are oriented transversely, in particular perpendicularly, to the base section 40 and run along the y-direction y.
- a first leg portion 41 and a second leg portion 42 are provided.
- first leg sections 38, 41 overlap one another.
- second leg sections 39, 42 overlap one another.
- “Overlap” means that the leg sections 38, 39, 41, 42 are arranged in pairs in such a way that the leg sections 38, 39, 41, 42 overlap or cover one another when viewed along the x-direction x.
- the leg sections 41 , 42 of the second sealing lip 33 are placed between the leg sections 38 , 39 of the first sealing lip 32 , viewed along the x-direction x.
- the first sealing lip 32 covers the second sealing lip 33 in the shape of a roof when viewed along the y-direction y.
- the entire sealing arrangement 31 runs with its two sealing lips 32, 33 completely around the receiving area 24 and thus completely encloses or borders it.
- the sealing arrangement 31 is not closed all the way round, but is interrupted or open at the overlapping areas 35, 36.
- the two sealing lips 32, 33 themselves do not each run completely around the receiving area 24.
- a cavity, slot or gap 43 (Fig. 4), in particular an air gap, which separates the first sealing lip 32 from the second sealing lip 33 separates.
- a gap 43 is associated with each pair of first leg sections 38, 41 or second leg sections 39, 42.
- the two sealing lips 32, 33, in particular the respective pairs of first leg sections 38, 41 and second leg sections 39, 42, together with the gap 43 each form a labyrinth seal 44 of the sealing arrangement 31 at the overlapping regions 35, 36.
- a labyrinth seal or “gap seal” is to be understood here as a non-contact seal in which the sealing lips 32, 33 do not touch one another and are therefore not in contact with one another.
- the sealing effect of the labyrinth seal 44 is based on an extension of a flow path of a fluid, for example washing-up liquid and/or fresh water or a liquid cleaning agent, through the gap 43 to be sealed, as a result of which the flow resistance for the fluid entering or exiting the feed device 15 is significantly increased .
- the lengthening of the flow path is achieved by the two sealing lips 32, 33 intermeshing or intermeshing, as explained above. This interlocking of the two sealing lips 32, 33 is only realized at the overlapping areas 35, 36. With the aid of the interrupted and flexible geometry of the sealing arrangement 31, the sealing function can be produced with consistently low operating forces.
- the sealing arrangement 31 acts in the region of the top edge 27 of the feed device 15 and on the side edges 29, 30 against washing liquor and/or fresh water penetrating from above in the orientation of FIG. In the area of the lower edge 28 and the side edges 29, 30, the sealing arrangement 31 acts against leakage of a liquid cleaning agent (not shown) out of the receiving area 24.
- the tightness is additionally ensured by the design of the sealing lips 32, 33 in the form of the labyrinth seal 44.
- the sealing lips 32, 33 are pressed or pressed laterally on a sealing geometry (not shown).
- the sealing lips 32, 33 are designed so flexibly that they can be deformed without great force.
- the sealing arrangement 31 is thus pressed between the receiving part 23 and the cover 21 in the closed state Z1.
- the use of the sealing arrangement 31 advantageously allows greater compensation for component and manufacturing tolerances of the cover 21, the receiving part 23 and/or the sealing arrangement 31 while the operating forces remain the same or are lower. As a result, a better sealing function of the entire addition device 15 can be achieved both against the ingress of liquid from the outside and against a loss of cleaning agent 25 from the receiving area 24 .
- a leaking addition device can lead to the cleaning agent 25 being activated earlier than desired, so that components of the cleaning agent 25 can already react and thereby lose their effect. If the cleaning agent 25 in the receiving area 24 is already wetted by a leak, it tends to form clumps, which can lead to the lid 21 becoming blocked when it is opened. This is reliably prevented with the aid of the addition device 15 which has the sealing arrangement 31 .
- a pre-dosing of a liquid cleaning agent can be made possible.
- a volume of a pre-dosage or a remaining amount of detergent can also be varied. Due to the flexibility of the sealing lips 32, 33, the risk of the sealing arrangement 31 sticking due to frictional forces is prevented.
- the use of the sealing arrangement 31 also opens up further degrees of freedom with regard to energy savings, which cannot be implemented with known addition devices.
