Description

Technical Field

[0001] The invention relates to a metering device for a water-carrying household appliance, in particular a washing machine or a washer-dryer, for metering solid and / or liquid fabric care agents. The invention also relates to a metering device, a household appliance and a method for operating a household appliance having a metering device. Background Art

[0002] In water-carrying household appliances such as washing machines and washer-dryers, the flushing tank has multiple functions and is a key component in the washing process. Its main function is to temporarily store the detergent manually added by the user so that it can be flushed into the drum or the laundry tub at a specified time. In addition, temporary dissolution of the detergent can also be carried out in the flushing tank.

[0003] The flush tank is usually designed with three chambers and includes a pre-wash chamber, a softener chamber and a main wash chamber. Most washing machines on the market have such a flush tank. However, the problem with existing flush tanks is that they require a lot of space in the upper area of ​​the household appliance. This limits the design freedom of the panel area and the control area of ​​the household appliance, and also limits the space available for other components of the household appliance.

[0004] Furthermore, household appliances with automatic metering devices have been disclosed, which can completely replace the conventional flushing tank and automatically meter the detergent. The user only needs to fill the storage container with detergent and softener. When purchasing a household appliance, the user usually has to decide whether to meter the detergent manually or automatically with the aid of a metering device. It is usually not possible to choose between manual or automatic metering of detergent in a household appliance, because space for the flushing tank is also required for an automatic metering system. Summary of the invention

[0005] Therefore, the object of the present invention is to provide a metering device for manually metering detergent, which enables more efficient use of space in a household appliance. The object is achieved by a metering device having the features of the preferred technical solution, a metering assembly having the features of the preferred technical solution, a household appliance having the features of the preferred technical solution, and a method having the features of the preferred technical solution.

[0006] According to one aspect of the invention, a metering device for a water-carrying household appliance is provided. The household appliance may be designed, for example, as a so-called front-loading washing machine or a washer-dryer.

[0007] The metering device is designed for metering solid and / or liquid fabric care agents. The fabric care agents can be solid or powdered detergents, liquid detergents, softeners, dyes, household appliance cleaners, descaling agents, etc.

[0008] The metering device according to the invention has a housing with a receiving chamber, which can be filled with at least one fabric care agent. A receiving groove is arranged in the receiving chamber. In addition, the housing has at least one first opening for introducing water into the receiving chamber and a channel for draining liquid, in particular in the form of at least partially dissolved fabric care agent, from the housing.

[0009] The receiving chamber can be connected to the second opening in a flow-conducting manner. The housing of the metering device is designed to be arranged on or in the door of the household appliance. This measure makes it possible to move the metering device with the function of a manual flushing slot into the door or door glass while retaining the same function. As a result, more structural space is available in the upper area of ​​the household appliance, because the conventional flushing slot (Einspülschale) of the three-chamber design is no longer required. In addition, the freedom of design and layout of the front panel of the household appliance is increased and the area for arranging control elements is also increased.

[0010] According to another aspect of the present invention, a metering assembly for a water-carrying household appliance is provided. The metering assembly has a door of the household appliance, in particular a front loading door for loading fabric products into a laundry tub from the side.

[0011] The door of the household appliance preferably has an inner wall and an outer wall. The inner wall and the outer wall are held together, for example, by a frame surrounding the edge and can be mechanically connected to the household appliance by a hinge. The inner wall is arranged to press against a door cup or a door seal of the household appliance in order to close the opening for filling the laundry tub in a fluid-tight manner. The inner wall thus protrudes into the household appliance at least in a region in the direction of the laundry tub.

[0012] On the contrary, described outer wall can be flush with the side surface or panel of household appliance substantially.Thus, between inner wall and outer wall of door, form unused volume, this volume can be transparently constituted.

[0013] Furthermore, the metering assembly according to the invention has a metering device, wherein the housing of the metering device projects or protrudes through a recess in the door inner wall into the volume formed between the door inner wall and the door outer wall and is connected to the door inner wall in a fluid-tight manner.

[0014] According to another aspect of the invention, a household appliance is provided. The household appliance can be designed in the form of a washing machine or a washer-dryer. The household appliance has a metering device according to the invention and a door for opening access to a laundry tub. The metering device is mounted in or on the door and protrudes at least partially into a volume of the door, which volume is formed between the inner wall and the outer wall of the door. The first opening of the metering device is connected to the outlet of the door cup flushing system of the household appliance in a flow-conducting manner.

[0015] Installing the metering device in the door makes it possible to remove the spray or flushing nozzle above the flushing slot, thus reducing biofilm formation and optimizing hygiene. Direct water inlet through the door cup or cup flushing system can further reduce product complexity and have a positive impact on the manufacturing cost and durability of the household appliance.

[0016] Furthermore, the reduction from a three-chamber design with a flushing chute to a one-chamber design with a manual dosing device simplifies the operation of the household appliance. Although the fabric care agent can be dosed manually, an automatic dosing device can also be installed in the household appliance. This is made possible by eliminating the conventional flushing chute. The user can thus choose between automatic and manual dosing of the fabric care agent as required.

[0017] According to another embodiment, the receiving groove of the receiving chamber has a siphon on the bottom side. The siphon is provided for connecting the receiving chamber directly or indirectly to the second opening of the housing in a flow-conducting manner.

[0018] When the siphon is directly connected to the second opening, the outlet of the siphon can directly lead to the second opening.

[0019] In the case of an indirect connection between the syphon and the second opening, at least one further component, such as an ejection ramp or an ejection labyrinth, is arranged between the outlet of the syphon and the second opening.

[0020] The syphon has an inlet in the bottom region of the receiving tank and forms a bottom section which communicates with the outlet of the syphon. The height of the bottom section defines the overflow height of the syphon. The inlet of the syphon is at a higher level than the outlet, so that the pressure difference combined with the effect of gravity leads to the liquid present in the receiving tank being sucked up.

[0021] Here, if the water level in the receiving chamber or receiving tank reaches the overflow level, the pumping process by the siphon automatically begins. If the water level falls below the inlet or there is no more liquid in the receiving tank, the pumping process automatically ends.

[0022] If the siphon is formed as an arcuate pipe section or a rotating body, the liquid can be sucked out of the receiving trough in a particularly simple technical manner. The siphon has an inlet in the region of the receiving trough bottom and an outlet below the receiving trough and / or at the second opening.

[0023] According to another embodiment, the syphon has a tube section which extends vertically through the receiving trough and protrudes vertically from the bottom of the receiving trough. The tube section forms an outlet of the syphon which opens below the receiving trough and / or at the second opening. A cap of hollow design is placed on the tube section. Advantageously, the cap can be removed for cleaning. Furthermore, the cap can be fastened to the tube section or the receiving trough with a friction fit and / or a form fit.

[0024] Advantageously, a radial and axial distance is formed at least in regions between the wall of the cap and the tube section, which transitions into the tube section in a flow-conducting manner. Thus, a U-shaped pipeline section is formed at least in regions, which is provided for conveying liquids.

[0025] The inlet of the siphon is formed between the bottom of the receiving trough and the radial distance between the cap and the pipe section. This measure makes it possible to provide a siphon which is technically simple in design and can be cleaned particularly easily. For cleaning, only the cap needs to be removed, thereby providing unhindered access to the receiving trough.

[0026] If the siphon or at least a part of the siphon is designed to be able to be taken out from the receiving chamber, the remaining liquid in the receiving tank can be discharged particularly simply. By this measure, the sanitary conditions in the metering device can be optimized and the formation of a permanent reservoir can be avoided.

[0027] The metering device can be particularly advantageously suitable for solid and / or powdered fabric care agents if the receiving chamber has a gauze insert which is arranged below the filling opening or first opening and above the receiving groove of the receiving chamber.

[0028] The mesh insert allows the fabric care agent to be easily separated into liquid and powder detergent and has the advantage that the fabric care agent can be pre-dissolved before being flushed into the laundry tub.

[0029] According to an advantageous embodiment, the gauze insert is designed as a holding device for a powdered and / or solid fabric care agent.

[0030] The gauze insert is designed at least in regions as a grid or sieve and has openings or meshes of a certain size through which the gauze insert can pass liquid and powdered fabric care agents in dissolved form. For example, the gauze insert can have openings with an average diameter of 800-2000 μm (micrometers). The gauze can be made of metal and / or plastic (e.g. polymer).

[0031] The hygiene of the metering device is significantly improved if the gauze insert can be removed, in particular pulled out, from the receiving chamber and the housing.

[0032] In an advantageous embodiment, the mesh insert is embodied as an insert or drawer.

[0033] The gauze insert that can be taken out from the metering device makes it possible to simply clean this gauze insert technically. Here, this gauze insert can be cleaned particularly easily under running water or in a dishwasher.

[0034] According to another embodiment of the metering assembly, the housing of the metering device has a peripheral edge section and is bonded to the inner wall of the door at the peripheral edge section. This measure makes it technically simple to install the metering device in the door of the household appliance, in particular in the door glass.

[0035] In an alternative or additional embodiment, a seal is arranged between the surrounding edge section and the inner wall. In this case, the housing is mechanically connected to the door while the seal is formed by the seal. This arrangement of the metering device makes it possible to dismantle or replace the metering device later.

[0036] According to another embodiment, an opening is provided in the outer wall of the door, which opening is connected to the filling opening of the metering device. As a result, the fabric care agent can be filled into the receiving chamber after the door of the household appliance is closed. Depending on the design, the gauze insert or the insulating layer can also be removed or pulled out of the metering device through the opening in the door.

[0037] In another embodiment, the metering device is arranged to be fastened to a glass insert of a door of a household appliance and to protrude into a cavity or volume of the door. By this measure, with only minor technical modifications to the door of the household appliance, the metering device can be introduced into a previously unused volume of the door and can be used instead of a flushing slot in the upper region of the household appliance.

[0038] According to another embodiment, the receiving chamber can be filled with the fabric care agent via a filling opening of the housing and / or at least one first opening, wherein the filling opening of the receiving chamber is accessible from the outside of the household appliance through an opening in the door to introduce the fabric care agent. Thus, the receiving chamber can be accessed via the at least one first opening to the interior of the household appliance, in particular the receiving chamber of the laundry tub, for filling with the fabric care agent.

[0039] Alternatively or additionally, the fabric care agent can also be introduced into the receiving chamber via a separate filling opening. Here, the filling opening can be accessed from the outside or the inside of the door or the housing. Here, when the door is closed, the inside faces the receiving chamber of the washing tub, while when the door is closed, the outside faces outwards or away from the household appliance.

[0040] According to a further aspect of the invention, a method for operating a domestic appliance having a metering device according to the invention is provided.

[0041] In one step, the door of the household appliance having the metering device is closed in order to produce a sealing effect of the door cup of the household appliance.

[0042] Depending on the design of the metering device, the fabric care agent can enter the receiving chamber before or after the door is closed. In an exemplary embodiment, the fabric care agent is positioned through an opening in the door outer wall and a filling opening in the receiving chamber. This step can be performed after the door is closed or before the door is closed. The filling opening is preferably closed by a filling valve or a filling closure device of the metering device.

[0043] In embodiments of the metering device without a filling opening, the fabric care agent can be placed or filled into the receiving chamber through the first opening of the metering device before the door is closed.

[0044] In a further step, the operating program of the household appliance is started. During the operation of the household appliance, water is fed into the receiving chamber through at least one first opening of the metering device by intermittently operating the door leather cup flushing device and at least partially dissolves the fabric care agent. This measure makes it possible to pre-dissolve the clothing care agent by slightly modifying the water inlet program of the household appliance. The water flow of the door leather cup flushing system is preferably intermittent to optimize the dissolution of the fabric care agent. Especially for powdered fabric care agents, too much water can cause the fabric care agent placed on the gauze insert to be squeezed or moved without dissolving. For example, about 0.5 to 1.5 liters of water can be intermittently injected into the receiving chamber to achieve optimal pre-dissolution of the fabric care agent.

[0045] Furthermore, a solution or liquid consisting of water and at least one fabric care agent is collected in the receiving tank.

[0046] After the collected liquid reaches the overflow height of the siphon, the siphon is automatically activated. As a result, the siphon conducts the liquid from the receiving tank. Here, the siphon can directly and / or indirectly transport the liquid to the second opening.

[0047] Through the second opening, the liquid reaches the laundry tub or at least one lye container of the household appliance, from which it is drawn off to moisten or treat the fabrics.

[0048] The advantages and features described above in relation to the apparatus also apply to the method, and vice versa. The individual features or aspects of the invention can be combined with each other and have the advantages explained in this context. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 1 A sectional side view of a household appliance 100 is shown with a metering device 10 according to one embodiment. The household appliance 100 can be designed in the form of a so-called front-loading washing machine or washer-dryer.

[0055] In addition to the metering device 10, the household appliance 100 also has a door 110. The metering device 10 is integrated in the door 110 or connected to the door 110. The door 110 is used to open the passage to the laundry tub 120. The fabric 200 to be treated by the household appliance 100 is placed in the laundry tub 120 by way of example.

[0056] The door 110 of the household appliance 100 has an inner wall 111 and an outer wall 112. The inner wall 111 and the outer wall 112 are fixed together, for example, by a frame 113 surrounding the edges and can be mechanically connected to the base body of the household appliance 100 by hinges (not shown).

[0057] The inner wall 111 is provided for pressing against a door cup 114 or a door seal of the household appliance 100 in order to close in a fluid-tight manner the opening for filling the laundry tub 120. The inner wall 111 thus protrudes at least regionally into the household appliance 100 in the direction of the laundry tub 120. In the illustrated embodiment, the door 110 is in the closed state.

[0058] On the contrary, the outer wall 112 is substantially flush with the side surface or panel 130 of the household appliance 100. Thus, an unused volume V is formed between the inner wall 111 and the outer wall 112 of the door 110, which volume can be designed to be transparent.

[0059] The metering device 10 according to the invention is arranged in or on the door 110 and projects at least in regions into a hitherto unused volume V of the door 110 which is formed between the inner wall 111 and the outer wall 112 .

[0060] Refer to the following Figure 2 and Figure 3The metering device 10 will be described. Figure 2 A detailed view of the metering device 10 with an inserted gauze insert 33 is shown. Figure 3 A detailed view of the siphon 40 in the bottom region of the receiving trough 13 is shown.

[0061] The metering device 10 is designed for metering solid and / or liquid fabric care agents. For example, the fabric care agent can be a solid or powdered detergent, a liquid detergent, a softener, a dye, a household appliance cleaner, a descaling agent, etc.

[0062] The metering device 10 according to the invention has a housing 11 with a receiving chamber 12 which can be filled with at least one fabric care agent. A receiving groove 13 is arranged in the receiving chamber 12 .

[0063] In the illustrated embodiment, the receiving chamber 12 can be filled with a fabric care agent via a filling opening 23 of the housing 11 or via the at least one first opening 21. Here, the filling opening 23 of the receiving chamber 12 projects through an opening 116 in the door 110 and is accessible from the outside of the household appliance 100 for inserting the fabric care agent.

[0064] Furthermore, the housing 11 has at least one first opening 21 for introducing water into the receiving chamber 12 and at least one second opening 22 for draining liquid, in particular at least partially dissolved fabric care agent, from the housing 11 .

[0065] At least one first opening 21 of the metering device 10 is connected in a flow-conducting manner to the outlet of a cup rinsing device 140 of the household appliance 100. In particular, water flowing out of the cup rinsing device 140 can be discharged along the inner wall 111 of the door 110, thereby reaching the first opening 21 and entering the receiving chamber 12.

[0066] The receiving chamber 12 can be connected with the second opening 22 in a diverting manner. In the illustrated embodiment, the receiving groove 13 of the receiving chamber 12 is provided with a siphon 40 at the bottom side. The siphon connects the receiving chamber 12 indirectly with the second opening 22 of the housing 11 through the flushing ramp 31.

[0067] The flushing ramp 31 is arranged below the receiving chamber 12 and communicates with the second opening 22 at the bottom side. The first opening 21 and the second opening 22 are exemplarily provided with a grid to prevent interaction with the fabric 200. The first opening 21 is introduced into a flap which can be removed in order to place the fabric care agent in the receiving chamber 12.

[0068] The siphon 40 on the bottom side is preferably located at the lowest position in the receiving tank 13. In addition, a bottom side slope is formed in the direction of the siphon 40 to facilitate the outflow of liquid.

[0069] Figure 1 The arrows in show the water flowing through the metering device 10. Advantageously, the lye or liquid is discharged through the second opening 22 in the form of dissolved fabric care agent.

[0070] In the illustrated embodiment, the syphon 40 has a tube section 41 which extends vertically through the receiving groove 13 and protrudes vertically from the bottom of the receiving groove 13. The tube section 41 forms the outlet 25 of the syphon 40, which opens below the receiving groove 13 and / or at the second opening 22. A cap 42 of hollow design is placed on the tube section 41. Advantageously, the cap 42 can be removed for cleaning. In addition, the cap 42 can be fastened to the tube section 41 with a friction fit and a form fit. Here, the cap 42 has a plurality of positioning elements 43 arranged on the inside.

[0071] By means of the positioning element 43, a radial distance Ar and an axial distance Aa are formed at least regionally between the wall of the cap 42 and the tube section 41, which transitions into the tube section 41 in a flow-conducting manner. As a result, a U-shaped pipeline section is formed at least regionally, which is provided for conveying liquid. The arrows indicate a possible flow of the liquid when the siphon 4 is activated. Here, the axial distance Aa and the radial distance Ar are designed to be circumferential, but can also be formed regionally, for example when the cap 42 is arranged non-centrally or eccentrically on the tube section 41.

[0072] The inlet 24 is formed between the bottom of the receiving groove 13 and the radial distance Ar between the cap 42 and the pipe section 41. For cleaning, the cap 42 can be removed, thereby providing unhindered access to the receiving groove 13 and the pipe section 41.

[0073] The syphon 40 thus has the inlet in the bottom region of the receiving tank 13 and forms a bottom section in the form of a body of revolution, which opens into the outlet 25 of the syphon 40. The height H of the bottom section defines the overflow height of the syphon 40. The inlet 24 of the syphon 40 is located at a higher level than the outlet 25, so that the pressure difference combined with the effect of gravity leads to the liquid present in the receiving tank 13 being sucked up.

[0074] Here, the pumping process by the siphon 40 automatically starts if the water level in the receiving chamber 12 or the receiving tank 13 reaches the overflow height H. If the water level falls below the inlet 24 or there is no more liquid in the receiving tank 13, the pumping process automatically ends.

[0075] Furthermore, a screen insert 33 is provided, which is located below the filling opening 23 in the receiving chamber 12. Here, the screen insert 33 divides the receiving chamber above the receiving groove 13 and in particular above the siphon 40. In the illustrated embodiment, the screen insert 33 is designed in the form of a pull-out drawer.

[0076] The gauze insert 33 serves as a storage surface for the powdered fabric care agent and can be removed from the housing 11 of the metering device 10 through the opening 116 in the door 110. The gauze insert 33 can be removed from the metering device 10, for example, for cleaning purposes.

[0077] Furthermore, the housing 11 of the metering device 10 also has a peripheral edge section 14, which is bonded, for example, to the inner wall 111 of the door 110. The inner wall 111 and the outer wall 112 are designed as door panes of the door 110. In the illustrated embodiment, the housing 11 forms the outer contour of the inner wall 111 after bonding to the inner wall 111 and completes the outer contour in such a way that the door cup 114 rests regionally on the inner wall 111 and regionally on the housing 11 and achieves a continuous sealing effect.

[0078] The housing 11 of the metering device 10 is thus fastened to the door pane of the household appliance 100 and projects into the unused volume V of the door 110. Here, the metering device fulfills the function of a manual flushing chute. As a result, more structural space is available in the upper region of the household appliance 100, since a conventional flushing chute in a three-chamber design is no longer required.
