Description

The invention relates to a metering device for the metered introduction of a pourable cleaning agent in a treatment room of a program-controlled cleaning device, in particular a dishwasher, with a reservoir which provides a stocking of detergent serving storage chamber, and with a metering unit, which provides an opening into a metering metering chamber , wherein the storage chamber is fluidly connected to the metering chamber in Dosierfall.

Program-controlled cleaning devices in general and dishwashers in particular are well known from the prior art, which is why a separate documentary proof at this point is not required.

Cleaning devices of the type in question typically have a washing container, which provides a washing compartment, also called treatment room. This rinsing or treatment space is accessible on the user side via a charging opening, which can be closed in a fluid-tight manner by means of a pivotally mounted flushing door. In the intended use case, the washing container serves to receive items to be cleaned, which in the case of a household dishwasher, for example, can be crockery, cutlery and / or the like.

For loading of items to be cleaned with rinsing liquid, the so-called rinsing liquor, the cleaning device has a spray device inside the rinsing container. This spraying device generally provides rotatably mounted spray arms, with typically two or three such spray arms being provided. In the intended use case, a loading of the items to be cleaned with rinse liquor by means of rotating spray arms.

In order to achieve an optimized cleaning result, process chemicals are used, which are supplied to the washing compartment during a cleaning process, in particular as an addition to the washing liquor. Such process chemicals can be For example, act detergent that programmatically added to the washing compartment of the cleaning device at a given time of a running cleaning program.

Detergents in liquid and solid form are known from the prior art. In this case, solid detergent in bulk powder form or as so-called tabs, that is in tablet form. However, practice has shown that it is possible to achieve the best cleaning results with pourable detergent in powder form.

When using a pourable detergent in powder form, a detergent dosing must be carried out by hand on the user's side before each start of a cleaning program. For this purpose, a cleaning device typically has, on the inside of the door, a reservoir which is to be equipped with a manually determining amount of cleaning agent. During the course of a cleaning program, this reservoir opens at a certain time of the wash program and the stockpiled detergent from the reservoir can be washed out by the rinsing liquor located in the washing compartment of the cleaning device.

In order to be able to carry out a detergent supply for a plurality of cleaning programs so that manual detergent dosing does not take place before the start of each cleaning program, dosing devices have been proposed, for example with US Pat DE 10 2013 104 391 A1 and the EP 2 928 288 A1 ,

The previously known from the prior art metering devices have an interchangeably arranged reservoir, which serves for the storage of detergent in an amount that is sufficient for a plurality of cleaning programs. The reservoir is rotatably mounted about an axis of rotation, wherein in the proper metering program controlled rotation of the reservoir is effected. For this purpose, a motor-driven drive device is provided, by means of which in the case of operation, a rotational movement of the reservoir is made.

For the purpose of detergent dispensing, the reservoir has a Outlet. This is dispensed portionwise detergent in the operating case. In this case, such a detergent dispensing occurs as a result of a rotational movement of the reservoir. Per 360 ° revolution of the reservoir, an always equal amount of detergent portion of the outlet is supplied and discharged from there with the interposition of a channel system in the washing compartment of the cleaning device.

In order to accomplish a detergent dosage, a metering unit is provided which has a metering chamber which opens into a metering opening. The storage chamber provided by the reservoir is fluidly connected in dosing to the dosing of the dosing. The storage chamber is therefore the storage of the detergent and the dosing worried in the case of use, the portionwise detergent dosage.

Dosing devices of the type described above have proven themselves in everyday practice. Nevertheless, there is a need for improvement, especially with regard to increased operational safety and simplified handling. It is therefore an object of the invention to further develop a metering device of the type mentioned in that, due to the design, increased operational reliability is achieved with improved handling at the same time.

To solve this problem, a metering device of the type mentioned is proposed with the invention, this is characterized in that the metering unit is formed as a separate component from the reservoir and the outside of the reservoir arranged interchangeable.

According to the prior art according to the aforementioned DE 10 2013 104 391 A1 the metering unit is designed as an integral part of the reservoir. The extent known supply reservoir thus provides on the one hand the pantry and on the other hand, the Dosiergeometrie, that is the metering and the metering channel ready. Although this type of embodiment has proven itself, but it is whether the complicated structure of the reservoir comparatively expensive to manufacture. In addition, any residual detergent remaining in the dosing chamber or the dosing channel can not be removed or can only be removed with increased effort on the part of the user, so that the risk, in particular when moisture is introduced, is eliminated there is an unwanted adherence to the detergent in or on the dosing geometry.

The embodiment of the invention provides a remedy. The metering unit is designed as a separate component to the reservoir. The reservoir therefore provides only the pantry, but no longer dosing geometry ready. This has the advantage that the reservoir is kept comparatively simple in construction and thus more cost-effective to manufacture.

When used as intended, the metering unit is arranged on the outside of the reservoir, and that interchangeable. It is therefore permitted on the user side to separate the dosing unit from the storage container by disassembly. This dismantling possibility of reservoir and metering unit provides essentially two advantages. On the one hand, the reservoir can be used both as a disposable container and as a reusable container, and this while avoiding waste. Because the dosing unit can be used repeatedly in any case, even if it is the reservoir to a disposable container. On the other hand, it allows the disassembly possibility to separate the dosing unit for the purpose of user-side cleaning of the reservoir. It can be prevented on the user side any blockage in the metering unit, which is particularly advantageous if it is the reservoir to a disposable container. From time to time, the dosing unit can be cleaned, which is favored by the interchangeable arrangement on the reservoir.

Another advantage of the exchangeable arrangement of the dosing unit on the storage container is that one and the same storage container can be combined with different dosing units. This may be useful, for example, if the user-side other Dosiergeometrien are desired, for example, to reduce or increase the dosed in Dosierfall detergent portions, if appropriate, depending on the particular cleaning agent used. This can be advantageous in particular over the entire service life of a dishwashing machine since the effectiveness of the detergent used can possibly be improved during this time, which makes it possible to reduce the detergent portion sizes. The exchange against a suitably designed metering unit can be taken into account.

It is provided according to a further feature of the invention that the dosing unit has a housing which provides the dosing chamber, the housing having a housing base body and a housing cover detachably arranged thereon. When the housing cover is removed, a direct access to the entire metering chamber, and thus both the metering chamber and the metering channel is possible, which simplifies cleaning of the metering unit by the user. Thus, it is allowed in the case of cleaning to remove the metering unit from the reservoir in a first step, and then disassemble the metering unit in a second step by the housing cover is removed from the housing body, which then allows unhindered access to the metering chamber. Any detergent residues, clumps and / or encrustations trapped in the dosing chamber can thus be removed without residue, making reuse of the dosing unit possible, which is also advantageous from an environmental point of view, in particular when using the dosing unit in combination with a storage container serving as a disposable container. The housing base body and the housing cover are preferably made of plastic. They are formed locked together, which on the one hand allows easy handling in the removal of the housing cover, but on the other hand also ensures that the housing cover does not accidentally detached from the housing body, especially not if the metering unit is separated in the event of replacement of the reservoir.

The metering unit has a detergent inlet on the reservoir side, which cooperates with a detergent outlet provided by the reservoir. In dosing, the storage container and the dosing unit are in fluidic connection, which is achieved after arranging the dosing unit on the reservoir in that the detergent outlet of the reservoir and the detergent inlet of the dosing unit are congruent to each other.

Preferably, the storage container is interchangeable arranged in a receptacle of the metering device and serves in particular the storage of detergent in an amount that is sufficient for a plurality of cleaning programs. According to a particularly advantageous embodiment of the reservoir is rotatably mounted about an axis of rotation, wherein the dosing case program controlled a rotational movement of the reservoir is effected. For this purpose, a motor-driven drive device is provided, by means of which in the case of operation, in particular in the dosing case, a rotational movement of the reservoir is made. The metering unit arranged on the outside of the storage container is moved together with the storage container. For the purpose of dispensing detergent, the reservoir has an outlet opening. About this is dispensed portionwise detergent in the dosing. In this case, such a detergent dispensing occurs as a result of a twisting movement of the storage container and the dosing unit arranged thereon. Per 360 ° revolution of the reservoir always an equal portion amount of detergent from the reservoir passes with the interposition of the metering in the washing compartment of the cleaning device.

In the dosing case, cleaning agent is dispensed via the detergent outlet of the storage container and first passes through the detergent inlet of the dosing unit into the dosing chamber provided by the dosing unit. This is subdivided into a dosing space and a dosing channel which is thus in fluidic connection, the dosing channel opening into the dosing opening. Cleaning agent originating from the reservoir thus initially reaches the metering space, from where it then arrives in the metering passage to the metering opening.

For the purpose of detergent dosing the dosing unit provides a corresponding dosing geometry, wherein the dosing chamber is subdivided into two fluidically interconnected partial areas, namely a dosing on the one hand and a dosing on the other hand, which are separated by a barrier. The barrier delimits the dosing space in such a way that upon a twisting movement of the storage container, first of all the dosing space is filled with a quantity of cleaning agent predetermined by the size of the dosing space. In a further twisting movement of the reservoir and arranged thereon dosing metered into the dosing amount of detergent is passed to the barrier past in the dosing in the direction of the dosing, without further detergent from the storage chamber of the reservoir flows into the dosing of the dosing. In the intended use case, the cleaning agent thus passes from the storage chamber into the metering chamber of the metering chamber, wherein the size of the metering chamber determines the amount of portioned cleaning agent. As a result of a further twisting movement of the storage container and the associated with this metering unit, the portioned detergent leaves the dosing and passes through the metering through the metering, whereby due to the continued rotational movement of the reservoir no detergent more the supply chamber can flow into the dosing of the dosing.

The reservoir has, according to a further feature of the invention, a reservoir body providing the container body and a container lid disposed thereon. In this case, the container body is preferably formed in the manner of a one-sided open shell, which open side is closed in the intended use case by the container lid.

According to a first alternative of the invention it is provided that the container body and the container lid are integrally formed or quasi one piece. "Quasi one-piece" means that the container lid is arranged on the container body or connected to this, that an at least non-destructive separation of container body and container lid is not possible. Such an arrangement of the container lid on the container body can be achieved for example by welding, by gluing and / or a comparable cohesive connection. Such a configuration is used in particular in a storage container used as a disposable container. After a proper emptying of the reservoir this is to be replaced with a fully filled, that is, new reservoir, the arranged on emptied reservoir metering unit can be used again.

It is provided according to an alternative embodiment of the invention that the container lid has a relative to the container body pivotable lid portion. The pivotally formed lid portion allows a user to open the reservoir in particular for the purpose of refilling with detergent. In the intended Dosierfall the pivotable lid portion is in the closed position, so that the reservoir is sealed. As soon as the storage container is emptied, refilling can take place, namely by pivoting the pivotable lid section into an open position, in which access to the storage chamber provided by the storage container is permitted. On the user side can therefore be filled by the resulting in the pivoted case of the lid portion feed opening detergent into the reservoir.

According to a further feature of the invention it is provided that the container lid pivotally arranged thereon closure tabs which abut in the closed position on a side wall of the container body on the outside. The locking tabs serve to additionally secure the container in the closed position. In this case, the closure tabs are arranged pivotably on the lid, which are to be grasped and pivoted on the user side in order to bring them into the closed position or open position. In the closed position, the closure tabs are on the outside of a side wall of the container body, which has the advantage that a transfer of the closure tabs in an open position on the user side is not possible if the reservoir is properly inserted into the recording provided by the metering device. Because the closure tabs are not accessible on the user side in a reservoir used in the recording of the metering device. These can only be grasped and pivoted on the user's side as intended when the storage container is removed from the receptacle of the metering device. By this constructive measure it is ensured that a refilling of the reservoir can only take place when the reservoir of the recording of the metering device is removed. This minimizes the risk that, in the event of incorrect filling of the storage container, an uncontrolled entry of cleaning agent into the metering device occurs.

It is provided according to a further feature of the invention that the container lid has a connecting portion projecting beyond the container body. This connecting section serves for the interchangeable arrangement of the dosing unit. For this purpose, the connection section provides a connection contour on the dosing unit side, for example in the form of a latching device and / or the like. The dosing unit is formed with a corresponding mating contour, which allows a position-safe, but nevertheless interchangeable arrangement of the dosing unit on the outside of the reservoir.

According to a further alternative of the invention it is provided that the container body has a closable feed opening. This embodiment is particularly suitable when the container body and the container lid are connected in one piece or quasi one piece with each other. The formation of a feed opening makes it possible to use a trained in such a way reservoir as reusable container. The loading opening is designed to be closable by means of a closure part, so that it is after a is excluded as intended filling of the reservoir that over the feed opening unintentionally and uncontrolled detergent exits.

To ensure that a refilling of the reservoir is then excluded when the reservoir is in the receptacle of the metering device is provided according to a further feature of the invention that the feed opening is formed in a side wall of the container body or the container lid opposite in the bottom of the container body , It is so constructive ensured that a refilling of the reservoir is only possible if the reservoir is first taken from the user side of the recording of the metering device. Only when the reservoir is removed a user-side access to the feed opening is permitted.

Fig. 1 can be seen in a purely schematic representation of an inventive cleaning device 1 in the embodiment of a household dishwasher. The cleaning device 1 has, in a manner known per se, a housing 2 which accommodates a washing container 3. The washing container 3 in turn provides a washing compartment 4 for receiving items to be cleaned. For loading the washing compartment 4 with items to be cleaned has the rinse tank 3 via a feed opening 5. This is closed in a fluid-tight manner by means of a Spülraumtür 6, wherein the Spülraumtür 6 is mounted drehverschwenkbar about a horizontal pivot axis.

Fig. 2 lets the Spülraumtür 6 in a plan view of the inner door panel 14 recognize, that is in the direction of II after Fig. 1 ,

As Fig. 2 can be seen, has the Spülraumtür 6 inside on a known from the prior art combination device 9, which serves in a conventional manner, for example, the inclusion of detergent, rinse aid and / or the like.

The cleaning device 1 has in addition to the known from the prior art combination device 9 via a metering device 7. This metering device 7 provides a reservoir 15 for storing detergent for a plurality of cleaning programs ready. In the course of its intended use, the corresponding amount of cleaning agent is removed from the storage container 15 provided by the metering device 7 per wash program cycle and fed to the washing compartment 4 of the washing container 3. In this case, the storage container 15 provided by the metering device 7 is preferably dimensioned such that it can receive cleaning agent in an amount which is sufficient for the completion of twenty to thirty flushing operations.

The metering device 7 has the arrangement of the reservoir 15 via a receptacle 10, which is closed by a pivotable lid 11 when properly inserted reservoir 15.

For dispensing of the metering device 7 stemmenden cleaning agent is a cleaning agent 8. This provides an outlet 12, which is covered by a cover 13. In this case, the lid 13 does not serve the fluid-tight closing of the outlet opening 12, but rather as a splash guard to minimize penetration of wash liquor into the outlet opening 12. For this purpose, the cover 13 on the outlet opening side, for example, webs, so that the cover 13 spaced from each other at the interposition of these webs comes to rest on the peripheral edge surrounding the outlet opening 12. The result is an opening gap through which rinsing liquor can pass into the outlet opening 12, but only in an amount which is required for flushing out cleaning agent located here.

As can be seen in particular from the presentation Fig. 3 results, the reservoir 15 is rotatable by means of a drive means 16, wherein a rotational movement of the reservoir 15 takes place about the axis of rotation 17. The drive device 19 has a motor assembly 18, which drives the reservoir 15 in Dosierfall.

When used as intended, the storage container 15 performs a 360 ° movement for the introduction of cleaning agent into the washing compartment 4. As a result of this twisting movement of the reservoir 15 provided cleaning agent is conveyed out of the reservoir 15, wherein the reservoir side provided metering ensures an always equal Dosiermengenabgabe. The amount of detergent dispensed from the reservoir 15 is then discharged via the cleaning agent 8 in the washing compartment 4. It serves for the fluidic connection of Reinigungsmittelauslass 8 and provided by the metering device 7 detergent dispensing opening 20 a flexibly formed tube 21, also called Ausschleusungsrohr, as can be seen in particular from the illustration Fig. 3 results.

As it turned out Fig. 3 Furthermore, the metering device 7 has a detergent channel 19, which opens into the detergent dispensing opening 20. in the In accordance with the intended use, cleaning agent dispensed from the metering device 7 flows through the cleaning agent channel 19 to the detergent-emitting opening 20 on the metering device side.

Between the detergent dispensing opening 20 and the detergent outlet 8, a tube 21 is interposed. This tube 21 has two end portions, namely the cleaning agent outlet 8 near end portion which provides a flange 23, and an end portion 24 opposite the Reinigungsmittelauslass 8. Between the end portion 24 and the flange 23, a bending portion is formed, in which region of the tubular jacket wave-shaped and because of which it is flexible.

Due to its bending portion, the tube 21 is flexible and thus formed pivotable.

Fig. 3 shows the tube 21 in a pivoted position, the so-called metering position, according to which the end portion 24 is pivoted in relation to the flange 23 by bending the tube 21. In this position of the tube 21, the tube 21 is fluidly connected to the detergent dispensing opening 20 of the detergent channel 19, which is why it is in its so-called metering, because in this position of the tube 21 from the reservoir 15 dispensed cleaning agent from the tube 21 to the detergent outlet 8 are promoted ,

For pivoting the tube 21 is a lever 25 which is pivotable about a pivot axis. As a result of a pivoting movement of the lever 25, it comes to the already described pivoting movement of the tube 21. For the purpose of connection of the tube 21 to the lever 25 is a holder 26 in the form of, for example, a clamp or clamp. This holder 26 surrounds the Dosiereinrichtungsseitigen end portion 24 of the tube 21 in the manner of a ring and serves as a connecting member between the lever 25 on the one hand and the tube 21 on the other. In the operating case, the lever 25 acts on the holder 26 and thus also on the trapped end portion 24 of the tube 21 a.

The pipe inlet opening of the tube 21 can be closed by means of a closure lid 27. This closure lid 27 is arranged pivotably on the lever 25, wherein arranged between a lever 25 and cap 27 cam device ensures that pivoting of the lever 25 also leads to a pivoting of the closure lid 27, in such a way that the tube 21 is closed in its non-metering position and in his in Fig. 3 shown dosing is open.

The others FIGS. 4 to 7 let reservoir 15 of the metering device 7 according to the invention each recognize in a perspective view, wherein the FIGS. 4 and 5 a first embodiment and the FIGS. 6 and 7 relate to a second embodiment.

The storage container 15 has a container body 28 and a container lid 30 arranged thereon. In the illustrated embodiment, the container body 28 and the container lid 30 are welded together, that is formed quasi one piece. The volume space enclosed by the storage container 15 serves as a storage chamber 29 for the storage of cleaning agents. According to the embodiment shown, the storage container 15 is designed as a reusable container, because it can be refilled via a closable with a cover 40 feed opening 39 with detergent.

To effect a detergent dosage, a metering unit 31 is provided. This is inventively designed as a reservoir 15 separate component and arranged on the outside of the reservoir 15 interchangeable.

The metering unit 31 has a preferably made of plastic housing 34. This housing 34 has a housing body 35 and a housing cover 36. In this case, the housing cover 36 is removably disposed on the housing body 35, which allows a user-side disassembly of the housing 34, in particular for cleaning purposes.

The housing 34 of the metering unit 31 accommodates a metering chamber 32. This is subdivided into two flow-related partial areas, namely a metering chamber 37 on the one hand and a metering channel 38 on the other. The metering channel 38 opens into the metering opening 33.

In the intended use case, the metering unit 31 on the reservoir 15th arranged, between the storage chamber 29 of the reservoir 15 and the metering chamber 32 of the metering unit 31 is formed a fluidic connection, so that in the dosing case detergent can be transferred from the reservoir into the metering unit 31.

According to the in the FIGS. 4 and 5 In the embodiment shown, the charging opening 39 is formed in the side wall 41 of the container body 28. The formation of the feed opening 39 in the side wall 41 provides the advantage that a user-side access to the feed opening 39 is not possible if the reservoir is properly inserted into the receptacle 10 of the metering device 7. This ensures that a user-side refilling of the reservoir 15 is only possible if the user has previously removed the reservoir 15 from the metering device 7.

Alternatively to the embodiment of the FIGS. 4 and 5 can also be provided to form the metering opening 33 in the bottom 42 of the container body 28, as the FIGS. 6 and 7 show, where Fig. 6 the feed opening 39 in the closed position, that is with lid 40 shows, whereas Fig. 7 the feed opening 39 in the open position shows.

A further embodiment of the storage container 15 according to the invention with a separate metering unit 31 shows the FIG. 8 in exploded view. In this case, the storage container 15 provides a compartment into which the metering unit 31 can be inserted. Here, too, the dosing unit 31 is formed as a separate component from the reservoir 15 and arranged on the outside of the reservoir 15 in the compartment interchangeable. The dosing unit 31 has a housing 34 with a housing body 35 and a housing cover 36 which is detachably arranged on the housing body 35 on the user side, so that cleaning of the dosing unit 31 can be carried out if necessary. The storage container 15 preferably has a separate closure lid 30, which can be removed from the container body 28 of the storage container 15 for the purpose of accessing the storage chamber on the user side. When the cover 30 is removed, it is therefore preferably possible to replenish the storage container 15 with cleaning agent. After filling the lid 30 is placed on the container body 28 for the purpose of closing the reservoir 15 again. FIG. 9 represents the embodiment of FIG. 8 a in a schematic perspective view with in the In this case, a fluidic connection between the storage chamber 29 of the reservoir 15 and the metering chamber 32 of the metering unit 31 is formed so that in the dosing case detergent can be transferred from the reservoir 15 in the metering unit 31. The metering chamber 31 of the metering unit 31 is again subdivided into two fluidically interconnected subregions, namely a metering chamber 37 on the one hand and a metering channel 38 on the other hand. The metering channel 38 opens into the metering opening 33. The metering process also takes place here as described above.
