Description

APPLICATION AREA AND PRIOR ART

The invention relates to a metering memory for receiving in a washing drum for the purpose of dispensing liquid detergent during a washing process and sets with such a metering memory.

A conventional dosing store has an outer housing with an interior, which comprises a receiving space for receiving detergent to be dispensed. The outer housing of such a dosing store has at least one outlet opening through which detergent can be dispensed from the receiving space into the washing drum without pressure.

Such a metering storage device is generally filled with a liquid detergent from a storage device before a washing process and then transferred to a washing drum. During a washing process, it remains in the washing drum and releases the liquid detergent held in it into the washing water or the laundry to be washed.

From the DE 3902355 A1 A dosing store with an outer housing is known which comprises an accommodation space in an interior for receiving detergent to be dispensed. The dosing reservoir comprises a filling opening which can be closed by a lid. From the EP 0 328 784 A1 and the WO 99/41442 A1 Dosing stores are known in which the filling opening can be closed by a part of the outer housing which has the function of a cover. For each filling, the dosing reservoir must be opened in order to transfer the detergent into the receiving space of the dosing reservoir.

TASK AND SOLUTION

The object of the invention is to provide a metering memory which can be used in particular in a washing drum for the purpose of dispensing liquid detergent during a washing process and which permits better handling of the filling process.

It is proposed here to further develop a dosing store mentioned at the outset in such a way that it has a filling opening which is accessible from an underside of the dosing store and a coupling device for coupling to a storage store. The dosing reservoir according to the invention also has a manually operable pump device for generating a negative pressure at the filling opening and thus for sucking in detergent from the storage reservoir into the dosing reservoir.

For this purpose, the metering reservoir has an push-in actuation handle on the outside of the outer housing, by means of which the pump device can be actuated, so that a pump chamber of the pump device can thereby be volumetrically changed and, as a result, generates the negative pressure at the filling opening.

A metering storage device according to the invention can be filled particularly easily with metered amounts of a liquid detergent from the storage device. For this purpose, the dosing reservoir comprises the filling opening, which is accessible from a bottom, and the coupling device, by means of which the dosing reservoir can be placed on the storage reservoir for filling and can thereby be coupled in a communicating manner to the storage reservoir. It also has the aforementioned manually operable pump device, by means of which the detergent can be sucked out of the storage reservoir in the coupled state. This pump device is very easy to use, since it can be operated manually from the outside without any preparation steps. This actuation is preferably carried out downwards and thus towards the storage reservoir. It is therefore simply pressed onto the coupled dosing reservoir from above to draw in detergent.

By integrating a pump device, the dosing reservoir can be filled from commercially available storage reservoirs. Such storage tanks are usually bottles for liquid detergent with a volume of 250 ml to 10 l, preferably with a volume of 2 l to 6 l. The dosing reservoir can be filled from this storage reservoir, its receiving space for receiving detergent preferably being between 10 ml and 500 ml, preferably 50 ml to 150 ml.

In order to be able to recognize how much detergent is already in the dosing reservoir, the outer housing of the dosing reservoir can be partially transparent, so that a fill level can be recognized from the outside. There is also the possibility that the outer housing has a measuring scale or a level marker having. For a particularly cost-effective implementation of the proposed dosing reservoir, it is preferred that the dosing reservoir is made of a plastic.

The aforementioned manually operable pump device is designed in such a way that it can convey liquid detergent from the storage device into the receiving space in the interior of the metering device. The pump device can be a classic pump device which has a pump chamber with a pressure-dependent opening inlet valve and a pressure-dependent opening outlet valve, which alternately opens and closes when washing detergent from the storage tank and when the previously sucked detergent is dispensed into the receiving space will. In its simplest form, the pump device of a metering store according to the invention is at least designed in such a way that it generates a suitable negative pressure, as a result of which the detergent is drawn into the metering store. The negative pressure generated is applied to the filling opening and causes the detergent to be sucked in from the storage tank. The use of a pump device that does not require complex valves is preferred. Such a pump device is explained below.

When the metering reservoir according to the invention is used conventionally, a single or multiple pump actuation can be provided in order to fill the metering reservoir for a washing process. Repeated pumping operations can be used to pump substantially equal volumes of the detergent into the storage reservoir of the dosing reservoir.

For the purpose of suction, the pump device has said pump chamber within an outer housing of the metering reservoir, which is designed such that it can be volumetrically influenced by a manual actuation of an actuating handle. It is particularly preferred that the pump chamber can first be reduced volumetrically in order to then be enlarged again manually or by the action of a resetting spring device. By means of this second step of enlarging the pump chamber, a negative pressure is generated within the pump chamber, which draws in the detergent from the storage reservoir. The excess pressure generated in the pump chamber during the previous volumetric reduction of the pump chamber can be transferred to the storage reservoir in order to support the conveying of the detergent. With an alternative design, however, there is also the possibility of letting this excess pressure escape into the atmosphere through a valve. The pump chamber can be formed by the entire interior of the outer housing or by a partial area thereof. Possibilities for this are explained in more detail below.

The pump device is designed and / or arranged in such a way that it can be actuated without opening the metering reservoir beforehand. The pump device can be actuated in particular by an elastically deflectable actuating handle on the metering reservoir or by a rigid actuating surface or an actuating lever.

The metering reservoir is preferably essentially spherical. Such a configuration is particularly easy to handle. In addition, this can be advantageous so that the metering memory within the washing drum does not damage the laundry to be washed during the washing process or snags on the laundry to be washed. In addition, other designs are conceivable, such as a cubic. The dosing reservoir preferably has a maximum inside diameter of 4 cm to 20 cm, preferably 6 cm to 12 cm. The interior preferably has a volume of 30 cm ³ to 4,200 cm ³ . The receiving space of the metering reservoir preferably has a volume of 10 cm ³ to 2,500 cm ³ . The volume of the receiving space is preferably between 30% and 60% of the volume of the entire interior of the metering reservoir.

According to a conventional dosing store, the outer housing of the dosing store has at least one outlet opening, through which detergent can be dispensed from the receiving space into the washing drum without pressure. With the coupling device pointing downward, the at least one outlet opening is preferably above the receiving space of the detergent to be dispensed, in order to prevent dispensing of the detergent before a washing process. It is preferably a plurality of outlet openings. The plurality of outlet openings is preferably distributed over the outer housing, so that uniform dispensing is possible regardless of the position of the metering reservoir. In the case of a plurality of outlet openings, it is preferred that the outlet openings are arranged essentially on a common and in particular horizontal plane. The metering reservoir preferably has three, particularly preferably six, outlet openings. The outlet opening or the outlet openings can be designed to be closable. This is preferred if the pump chamber of the pump device is formed by the entire interior of the metering reservoir.

So that the detergent can be dispensed into the washing drum without pressure, the at least one outlet opening is dimensioned such that the detergent or a detergent / water mixture can run out of the metering reservoir. The at least one outlet opening is preferably designed in such a way that the detergent can also be dispensed without centrifugal forces which prevail when the washing drum rotates. Minimal clear cross-sectional area is preferred the at least one outlet opening of 4 mm ² , preferably of at least 10 mm ² .

As already explained at the beginning, the metering reservoir is equipped with a coupling device which is used for coupling to the storage reservoir. It is preferred that the coupling device is designed in such a way that the dosing reservoir can be placed in a cap-like manner on the storage reservoir. With such a configuration, the dosing reservoir can be coupled to the reservoir reservoir in a simple step by being placed on the reservoir reservoir from above.

In the simplest case, the coupling device has a sealing surface that corresponds to the storage device and a coupling device provided thereon, so that a suction path that is essentially tight to the outside is created, through which the detergent can be drawn from the storage device into the dosing storage device without the negative pressure being released the pumping device can be compensated for by the atmosphere. Since it is usually not a question of very precise dosing, it is sufficient if the suction path is sufficiently dense to permit delivery. Smaller leaks are therefore harmless, although ideal tightness should be sought.

The coupling device preferably comprises an axial securing device, so that the metering reservoir is secured against accidental pulling off on the storage reservoir in a non-positive or positive manner. For this purpose, the coupling device can comprise a snap connection, which brings about the axial securing of the metering reservoir.

This axial securing can particularly preferably be created by a coupling bayonet or thread. A coupling device that limits rotational movement is advantageous. In the case of a thread, this is the case, for example, since screwing the metering reservoir onto the storage reservoir is only possible up to an axial stop and then further turning is prevented. The purpose of the rotational movement limitation mentioned is explained below.

An alternative and also very simple coupling device comprises a web or a groove which, with a groove or a web on the side of the coupling device on the storage reservoir, enables a coupling movement of the metering storage which limits rotation.

Different configurations of the coupling device are discussed in detail below.

As explained above, the filling opening is in communication with the storage reservoir in the coupled state, so that the tight or largely tight suction path between the metering reservoir and the storage reservoir is created. Through the filling opening, the negative pressure generated in the pump chamber when the pump device is actuated can draw in the detergent from the storage reservoir. For this purpose, the pumping chamber is operatively connected to the filling opening at least in phases, so that the negative pressure acts into the storage reservoir. For this purpose, it can be preferred that there is a riser pipe in the storage tank, which extends below the liquid level of the detergent, so that the detergent can be sucked in.

The filling opening is preferably provided at an inner end of a receiving shaft which extends from below into the metering reservoir. The receiving shaft is provided for receiving an outlet connection of the storage tank. The receiving space can extend in a ring around the receiving shaft.

In this embodiment, the receiving shaft extends vertically upward from the underside of the metering reservoir, as a result of which an annular region is formed around the receiving shaft in the interior of the metering reservoir. The receiving shaft is formed by a circumferential wall that surrounds an open area. The filling opening is provided at the end of this receiving shaft and is thus set higher than a bottom of the metering reservoir. This prevents accidental release of detergent from the receiving space through the filling opening of the dosing reservoir before and during transfer into the washing drum. An alternative or additional measure to ensure this is the provision of an inlet valve at the filling opening, which prevents undesired escaping of detergent from the interior of the metering reservoir.

The free area of the receiving shaft also serves for the coupling receiving of an outlet connection of the storage tank. The dosing reservoir is placed on the outlet port for coupling to the reservoir and secured there by means of coupling devices which are preferably provided on both sides and matched to one another.

The filling opening is provided at the end of the above-mentioned receiving shaft. Here, an end wall is preferably provided at the inner end, which is penetrated by the filling opening. It is particularly preferred that this end wall tapers upward in the direction of the filling opening. The end wall can taper conically. However, configurations are also possible in which the end wall tapers upward in steps, for example. The filling opening is thus arranged at a particularly high or even the highest point of the receiving shaft. As a result, the detergent sucked in after a pumping process can run off into the receiving space, and running back into the store is minimized or prevented.

The metering reservoir preferably has at least one diaphragm for closing the at least one outlet opening. This diaphragm can be displaced with respect to the outlet opening between a closed position covering the outlet opening and an open position exposing the outlet opening.

In its open position, the cover enables detergent to pass through the outlet opening. In the closed state, this is prevented or at least made more difficult. The screen can temporarily prevent the detergent from being dispensed by displacing the screen relative to the outlet opening in such a way that it closes it, in particular covers it from the inside. This means that the dosing reservoir cannot be accidentally emptied prematurely when the transport is full.

In the case of a configuration of the dosing store with this diaphragm, a separate cover of the supply store can be dispensed with, since this can instead be closed with the diaphragm by the dosing store which can be used in the manner of a cap. In such a case, the dosing reservoir thus assumes a dual function as a lid or dosing reservoir used in the washing drum in some cases.

The aperture can be shifted between the closed position and the open position by manual intervention. There is the possibility that a switching element separate from the outer housing can shift the cover between the closed position and the open position. The diaphragm is preferably designed in such a way that it changes to the closed position as a result of the coupling process with the storage reservoir. It is further preferred that the diaphragm is designed such that it changes into the open position when uncoupled.

There is the possibility that the cover can be displaced by a switching element within the outer housing when coupling between the closed position and the open position.

Particularly in the case of an embodiment of the outer housing, which comprises a plurality of housing parts, it can be preferred, however, that the diaphragm changes between the closed position and the open position by displacing these housing parts with respect to one another. In a further embodiment, the diaphragm can be closed by the actuation handle of the pump device while the pump device is actuated.

In the case of an embodiment with a large number of outlet openings, the at least one diaphragm can be designed in such a way that the outlet openings can be closed individually or in groups. However, it is preferred that in a configuration with a plurality of outlet openings, at least two diaphragms can always be moved together, and preferably with a single diaphragm element, on which the diaphragms are provided in one piece, between the closed position and the open position. It is preferred that, in a configuration with a plurality of outlet openings, all diaphragms can be displaced together in order to switch between the closed position and the open position with one movement.

Due to the above-mentioned diaphragm, the pump device can be designed to be particularly simple, since the interior of the metering reservoir can also be used as a pump chamber when the diaphragm is in the closed state. In such an embodiment, the diaphragm is preferably designed such that it closes the outlet opening essentially in an airtight manner. As a result, the negative pressure generated in the pump chamber can be used to suck in the detergent. Even in a configuration in which, due to an insulated pump chamber, sealing of the outlet opening by the diaphragm is not absolutely necessary, sealing can be advantageous in order to prevent the detergent from passing through the outlet opening. The sealing requirements for the panel can be lower in such an embodiment.

In a preferred configuration, the outer housing can have two partial shells accessible from the outside, namely an upper partial shell and a lower partial shell. These partial shells are coupled to one another.

The partial shells can be coupled to one another in such a way that the metering reservoir can be opened. Here, the partial shells can either be completely separated from one another or else have a hinge, as a result of which the metering reservoir can be opened.

However, the two partial shells are particularly preferably coupled to one another in such a way that they can be moved relative to one another without the metering store being opened as a whole. Such a closed relative mobility is particularly suitable for a design in which the displacement of the diaphragm relative to the outlet opening is brought about by displacement of the partial shells relative to one another. Such a coupling of the two partial shells can include, for example, guide grooves and / or guide webs in the edge region of the partial shells, which together form a guide.

With such a design, the at least one outlet opening is preferably provided on one of the partial shells, preferably the upper one, and the at least one diaphragm is provided on the other partial shell. In such an embodiment, the partial shells can be moved relative to one another between a first relative position and a second relative position in the coupled state. In such an embodiment, the partial shells do not have to be separated from one another and / or opened to switch between the first relative position and the second relative position. In the first of the relative positions of the partial shells mentioned, the at least one diaphragm covers the at least one outlet opening and in the second relative position of the partial shells, the at least one diaphragm exposes the at least one outlet opening. Such a design can do without a separate switching element on which the diaphragm or diaphragms are provided, since moving the partial shells causes a change between the closed position and the open position.

The mobility between the first and second partial shells can be a translative movement. In this case, for example, one of the two partial shells can be moved relative to the other partial shell, for example downwards, as a result of which the screen closes the outlet opening. With such a translative movement, it is particularly preferred that this movement coincides with the movement of the pump actuation. With such a design, the diaphragm can be closed and the pump device can be actuated with just one actuation.

In a particularly preferred configuration of the mobility between the first and second partial shells, the partial shells can be rotated relative to one another. With such a design, the partial shells are in particular rotatable against one another about an axis of rotation. In the case of an essentially spherical outer housing, the partial shells are preferably designed in the manner of hemispheres. However, other and asymmetrical subdivisions are also conceivable, in which the partial shells occupy spherical segments of different sizes in the outer housing. Even in a configuration in which the outer housing is not essentially spherical, it is preferred that the individual housing parts have a mobility relative to one another which corresponds to the mobility of the partial shells described. In this context, it is preferred that the housing parts are movable relative to one another about an axis of rotation, irrespective of their external design, in particular by a circular guide between the housing parts. This axis of rotation preferably coincides with a central axis of the coupling device described or the receiving shaft.

It is preferred that the two partial shells have a limitation of the rotary movement in such a design. This simplifies the simple production of the opening and closing states. Such a limitation is particularly advantageous in connection with a coupling device, which is designed as a thread or coupling bayonet. These advantages are explained below in connection with the coupling device.

As already explained, in the simplest case the coupling device can be a sealing surface which, on the basis of the weight with which the dosing reservoir rests on the storage reservoir and possibly the actuating force exerted for the pumping process, enables adequate sealing. However, it is preferably a coupling device, by means of which the metering reservoir can be attached to the storage reservoir in a non-positive or positive manner.

In a particularly preferred embodiment, the coupling device is provided in the open area on the wall of the receiving shaft mentioned. The coupling device is particularly preferably the internal thread already mentioned above, by means of which the dosing reservoir can be screwed onto a corresponding external thread of the storage reservoir in a cap-like manner. The coupling device can be designed in such a way that it enables a coupling to the storage unit that limits the rotational movement in one direction of rotation. The rotation lock that can be produced in this way is particularly advantageous in the case of a metering store with rotatably switchable diaphragms, as will be explained further below.

This coupling, which limits the rotational movement, leads to the fact that when the metering storage device is coupled to the storage device due to the design of the coupling devices on the metering storage device and a state can be produced on the storage device in which the metering storage device cannot be rotated further in relation to the storage device at least in one direction of rotation. Such a limitation can be achieved, for example, via the thread mentioned with a defined end point or else the coupling bayonet mentioned.

Such a coupling device is advantageous, in particular, when the metering reservoir is designed with the above-described panels on housing parts that can be rotated. In the coupling device, in which the metering accumulator is coupled to the supply accumulator by means of the rotary movement, the metering accumulator can be coupled in only one step and the relative position of the orifices can be changed. Particularly in connection with the coupling, which limits the rotational movement, to the supply store, by applying moment to a housing part of the metering store, this housing part can be rotated with respect to the supply store and thereby also with respect to another housing part. By means of this coupling, which limits the rotational movement, the diaphragm can be brought into the closed position when coupling. With a uniform movement, the user can therefore place the dosing reservoir on the storage reservoir, screw it on if necessary, and thereby also move the aperture or the apertures into the closed position.

In a preferred embodiment, the coupling device is designed in such a way that when the metering reservoir is uncoupled by the rotary movement, the diaphragm is opened again accordingly. In this case, it is preferred that the coupling device is designed in such a way that the force application or torque application for decoupling the metering accumulator is higher than the force application or torque application required for transferring it to the open position of the diaphragm. Accordingly, a decoupling movement by the user initially leads to a shift of the diaphragm into the open position and then to a release of the coupling.

In particularly simple embodiments, however, the coupling device can also be the above-mentioned web or a groove. In this case, the web or the groove preferably extends along the main direction of extent of the receiving shaft and corresponds to a groove or a web on the outlet connection of the storage reservoir in order to prevent twisting between the metering storage and the storage reservoir.

In further embodiments, a coupling device can comprise further elements such as, for example, a snap connection, which prevents the dosing reservoir from falling off or slipping off the reservoir. A coupling device with a coupling bayonet already mentioned is also possible, that is to say a coupling device consisting of an axial and a circumferential groove and a cooperating holding body which is movable within the groove. In the case of such a design, the coupling device comprises the said grooves or the holding body on the side of the metering reservoir.

The pump device described above preferably has an externally accessible wall section on the outer housing of the metering reservoir as an actuating handle, which is movable relative to the filling opening and which can be pushed in manually in such a way that the interior of the metering reservoir or one that can be isolated from the rest of the interior can be reduced by pressing in the wall section Pump chamber can be effected.

Pump actuation can be carried out in a particularly simple manner through such a configuration of the actuation handle. In an embodiment in which the wall section is arranged at the top of the metering reservoir, the pumping device can be done by simply depressing the movable wall section.

As described above, in the case of a pump actuation, the pump device can have a pump chamber which is formed by the entire interior of the metering accumulator and which becomes smaller during the pump actuation. This means that an overpressure that arises when the pumping chamber volume is reduced and a subsequent negative pressure that arises when the pumping chamber volume increases in the entire interior. Such a design can be used to draw a comparatively large amount of liquid with just one actuation. The minimum pump chamber volume is preferably less than 90% of the maximum pump chamber volume, so that the pump volume is preferably at least 10% of the interior volume.

Alternatively, the pumping device can have a pumping chamber that does not occupy the entire interior, but is formed by a partial area of the interior of the metering reservoir, this pumping chamber being isolable at least in phases from another area of the interior during a pumping process.

In such an embodiment, the pump device can be isolated both upstream of the pumping chamber in the direction of the filling opening and downstream in the direction of the receiving space by means of one valve each. Such a solution with two valves is, however, relatively complex. It is therefore preferred that the pump chamber is delimited by a compressible peripheral wall that is open on one side, particularly preferably downwards. Such a pump chamber can be formed, for example, by a bellows. Such an insulated pump chamber is preferably connected to the elastically deformable wall section. According to the above embodiment, such an insulated pump chamber is downsized during the pumping operation.

So that the pump chamber is insulated from the rest of the interior of the metering reservoir during actuation, the compressible peripheral wall comprises a sealing edge. This sealing edge is preferably arranged on an open side, preferably the underside of the bellows, which lies opposite the deformable wall section. The sealing edge is arranged or designed in such a way that, when actuated, it bears against a sealing surface surrounding the filling opening, against the end wall of the receiving shaft. The sealing edge and the sealing surface come into sealing contact with one another when the movable wall section is pressed in and the subsequent resetting, that is to say when the pump is actuated, so that the detergent can subsequently be sucked in under the effect of the negative pressure in the pumping chamber. The sealing edge and the sealing surface thus form a kind of simple valve.

The negative pressure is generated when the compressible wall returns to its uncompressed original state, but is still in contact with the sealing surface. The detergent is thus sucked into the pumping chamber from the storage tank. Such an embodiment avoids the use of complex valves. This embodiment can be implemented with the orifice described above. In this embodiment, the negative pressure can also be generated when the diaphragm is in the open position and the detergent can be sucked in.

The pump chamber wall is particularly preferably connected in one piece to the movable wall section.

In further embodiments, the wall section can be formed by a rigid actuating hood, which can be pressed in, for example, against the force of a spring device. However, it is preferred that the wall section is provided by an elastically deformable wall section is formed. As a result, the pump device can be manufactured particularly cost-effectively.

The elastically deformable wall section is preferably a material with an elastic modulus in the range from 0.3 GPa to 4 GPa, preferably 0.6 GPa to 2 GPa, and particularly preferably in the range from 0.7 GPa to 1 GPa.

The elastic wall section is preferably designed in such a way that it deforms back into the starting position due to its inherent restoring force after actuation. It can be preferred that the metering accumulator comprises further spring devices, for example a separate coil spring, which deforms or moves the wall section back into the starting position. A separate spring device is particularly preferred in one embodiment of a rigid wall section.

A preferred possibility of realizing an elastically deformable wall section is that the elastically deformable wall section forms one of the partial shells, which is formed as a whole from an elastic material, preferably at least one outlet opening being provided in this partial shell.

In further embodiments, the elastically deformable wall section can be provided on a rigid support section on one of the partial shells. In such an embodiment, it is preferred that this carrier section is coupled to the other partial shell. In such an embodiment, the carrier section has a double function, since it comprises the wall section and the coupling with the other partial shell. In the embodiment with the rigid support section, it is preferred that the support section comprises the at least one outlet opening and the other partial shell comprises the cover.

The elastically deformable wall section is preferably firmly connected to the rigid support section, since these components do not have to be separated from one another for actuation of the pump device. It may be preferred that the rigid support section comprises a support structure. This support structure can lie both in the interior of the support section and can be connected to it. The elastically deformable wall section and the rigid support section can be produced in a two-component injection molding process and thus comprise materials with different properties in a one-piece partial shell

Also encompassed by the invention is a set of a first type comprising a dosing store and a storage store. The dosing reservoir is designed as described above.

The storage tank has an outlet nozzle for removing detergent. The coupling device of the metering accumulator is adapted to the outlet nozzle in such a way that the metering accumulator with its coupling device can be attached tightly to the outlet nozzle.

It can be preferred that the metering reservoir can be attached to the outlet connection of the storage reservoir in such a way that it takes on the function of a cover when not in use. In this context, it can in particular be preferred that the metering memory comprises the at least one orifice plate described above and its interior can thus be isolated from an environment.

An embodiment is possible in which the dosing reservoir is a separate product which can be used as an accessory for storage reservoirs with liquid detergent. However, it is preferred that the dosing storage device is combined with the storage storage device of a classic detergent bottle and is thus delivered to an end customer together with a storage storage device.

The outlet connector and the coupling device are preferably designed to make a rotationally fixed connection, in particular the outlet connector and the coupling device are each provided with a thread or together form a coupling bayonet.

The invention also encompasses a set of a second type comprising a dosing store and a removal insert for an outlet connection of a storage store. The metering reservoir is designed in the manner described above. The removal insert is used for the tight connection between the dosing reservoir and a storage reservoir. It preferably has a coupling surface, by means of which it can be coupled to the outlet connection of a storage reservoir.

The removal insert is an assembly that is permanently connected to the storage tank during operation. However, the set mentioned does not include the supply store, or at least not with the removal insert already connected.

The removal insert is detachably attached to the dosing reservoir, so that when the dosing reservoir is first coupled to a storage reservoir, it is transferred to the outlet port. The removal insert is then coupled to the storage tank in such a way that the attachment to the Dosing storage is easier to solve than the connection to the storage storage. In particular, it is preferred that the coupling surface is arranged on the side of the removal insert, so that when it is pushed into the outlet connection of the storage reservoir, it is supported against an inner wall of the outlet connection, whereby the removal insert is firmly connected to the storage reservoir. This coupling can be non-positive or frictional. With each subsequent decoupling of the dosing tank, the removal insert remains on the outlet connection of the storage tank.

The removal insert is particularly preferably designed such that its shape corresponds to the end wall of the receiving shaft of the dosing reservoir, so that a tight connection between dosing reservoir and storage reservoir is made possible. For this purpose, the removal insert comprises an outlet opening which, when the metering reservoir is coupled, corresponds to its filling opening.

Usually, the manufacturer of a dosing store according to the invention is not identical to the manufacturer of a storage store. It can therefore be preferred that the dosing store is present together with a removal insert for an outlet connection of the store. This preassembly unit comprising the dosing store and the removal insert can then be coupled by the manufacturer of the storage store in the course of assembly to the storage store, with a type of transfer of the removal insert from the dosing store to the storage store.

In particular when using the metering reservoir with a storage reservoir without a riser pipe, it can be preferred that the removal insert comprises a corresponding riser pipe. This riser pipe is preferably connected to the removal insert in such a way that the suction path extends to the bottom of the storage reservoir.

The set of metering storage and removal insert mentioned is the embodiment of a general consideration, which is also part of the invention. According to this more general consideration, a metering set for dispensing a liquid, in particular for dispensing said liquid detergent into a washing drum during a washing process, is proposed. The dosing set comprises a main reservoir with a larger liquid storage and a dosing device with a smaller liquid storage. The metering device is provided for repeated coupling to the main reservoir for the purpose of filling the smaller liquid reservoir from the larger liquid reservoir and for the subsequent repeated disconnection. The dosing set includes a line insert for the conduction of liquid from the main reservoir to the dosing device is adapted to an outlet opening of the main reservoir in such a way that it can be permanently connected to it in a positive or non-positive manner. The dosing set is in an intermediate assembly state. In this intermediate state, the line insert is temporarily attached to the metering device in such a way that it couples to the main reservoir when the metering device is first connected to the main reservoir and detaches from the metering device the next time the metering device is uncoupled and remains on the main reservoir.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Fig. 1 shows a set of a dosing store 10 and a storage store 100. The storage store 100 contains detergent 105, which is intended to be transferred to the dosing store 10 so that the then loaded dosing store 10 is then brought together with laundry into a washing drum, where the detergent 105 in In the course of the washing process through outlet openings 62 is released to the laundry.

The outer housing 12 of the metering reservoir 10 comprises a lower partial shell 40 and an upper partial shell 60, the upper partial shell 60 comprising a plurality of outlet openings 62 and an elastically deformable wall section 64. The lower partial shell 40 forms a receiving space 16 for detergent 105. The metering memory 10 comprises a measuring scale 18 on this lower partial shell 40, which is transparent at least in sections, for reading the fill level. In Fig. 1 a filling opening 42 of the metering reservoir 10 on its underside is not visible.

The storage reservoir 100, which is designed like a bottle in the present case, comprises an outlet connection 104 with a removal insert 108 already mounted thereon. The removal insert 108 comprises a central outlet opening 106.

2 to 4 illustrate the sequence when filling the dosing reservoir 10.

Fig. 2 shows the first step in which the dosing reservoir 10 is coupled to the reservoir reservoir 100 with a coupling device 46. The metering reservoir 10 and the storage reservoir 100 are each equipped with a thread for this. The metering reservoir 10 is screwed onto the reservoir 100 in the direction of arrow 6. The metering memory 10 is applied as far as far the thread allows it. During this screwing-on process, the outlet openings 62 are closed, as will be explained below.

After completion of the coupling and closing of the outlet openings 62 leads through an in Fig. 3 Depressing the wall section 64 shown in the actuating direction 7 to reduce the interior 14 of the metering reservoir 10 acting as a pump chamber, so that when the wall section 64 springs back, a negative pressure is generated in the interior 14 of the metering reservoir 10, which detergent 105, not shown, is stored in the reservoir 100 sucked into the dosing reservoir 10.

In conclusion is in Fig. 4 shown that the dosing reservoir 10 can be separated from the storage reservoir 100 by means of a loosening thread rotation in the direction of the arrow 8, so that the dosing reservoir 10 can be transferred, for example, to a washing machine. Depending on the specific configuration of the metering reservoir 10, the outlet openings 62 open, as will also be explained below.

Although the Figures 1 to 4 Show a specific embodiment, all aspects mentioned apply to all embodiments of the invention, which are described below.

Fig. 5 shows a first embodiment of the metering reservoir 10 according to the invention in detail in an exploded view. This exemplary embodiment is exemplary of that in FIG 1 to 4 shown identical.

The upper partial shell 60 comprises the elastically deformable wall section 64 and a total of six outlet openings 62, which are distributed in a circle at a lower end of the upper partial shell 60.

The lower part shell 40 comprises on its underside the said receiving shaft 44, which projects into the interior 14 of the metering reservoir 10. At the upper end of the receiving shaft 44 there is an inwardly tapering end wall 41 which is pierced in the center by the filling opening 42 already mentioned. The partial shell 40 comprises a panel structure with a plurality of panels 48, each of which can close an outlet opening 62 and together the entirety of the outlet openings 62 in an assembled state. For a particularly tight closure of the outlet openings 62, the screens 48 each have an elevation 49 is positioned such that they protrude into the respective outlet openings 62 in an assembled and closed state. The lower partial shell 40 has a connection device 52 on an upper edge, by means of which it connects to a connector Fig. 6 Connection device 78 shown can be connected to the upper partial shell 60. The connecting device 52 is at least one guide groove or at least one guide web.

The removal insert 108 already mentioned is provided for mounting in the outlet connection 104. A riser pipe 110 is attached to the removal insert 108. The removal insert 108 and the riser pipe 110 can be coupled together to the outlet connection 104 of the storage device 100. For this purpose, the removal insert 108 has a coupling surface 109 which, in the assembled state, lies firmly and sealingly against an inner wall of the outlet connection 104 of the storage reservoir 100.

Fig. 6 shows the inside of the in Fig. 5 partial shell 60 shown. The partial shell 60 comprises a connecting device 78, by means of which it can be connected to the lower partial shell 40 and its connecting device 52. The connecting device 78 also has at least one guide groove or at least one guide web.

In the joined state of the partial shells 40, 60, that is to say in a state in which the connecting devices 52, 78 are connected to one another, the partial shells 40, 60 can be rotated relative to one another about an axis of rotation 2, so that the orifices 48 with respect to the outlet openings 62 thereby also result are movable between an open position and a closed position. In this embodiment, the axis of rotation 2 coincides with a central axis 4 of the coupling device 46 and together forms a main axis 5.

The upper part shell 60 comprises on the side 76 facing the interior 14 behind each outlet opening 62 a holding structure 79 which is unidirectionally accessible in the circumferential direction and which, in the assembled state, presses the panels 48 of the lower part shell 40 against the outlet openings 62 in order to seal the interior 14 to guarantee. The holding structures 79 also limit the rotatability of the partial shells 40, 60 relative to one another in one of two directions of rotation.

The upper shell 60 also includes a plurality of limiters 77, which limit a rotational movement of the upper and lower shell 40 and 60 in the direction of the opposite direction of rotation, so that the covers 48 of the lower shell 40 are limited in their movement between the holding structures 79 and the limiters 77 in their rotary movement.

That in the Fig. 7 The embodiment shown in a disassembled state corresponds to the embodiment of FIG 5 and 6 . The upper partial shell 60 is formed in one piece and comprises the elastic wall section 64 and the plurality of outlet openings 62. On the side of the outlet openings 62 facing the interior 14, the upper partial shell 60 in each case has the holding structures 79 overlapping the outlet openings 62.

The lower partial shell 40 comprises a number of diaphragms 48 corresponding to the number of the outlet openings 62 of the upper partial shell 60, which are arranged in such a way that they enable the outlet openings 62 to be sealed in an assembled state. Also shown is the receiving shaft 44 extending from below into the metering reservoir 10, at the upper end of which the inwardly tapering end wall 41 is arranged, which in the middle encompasses the filling opening 42. The receiving space 16 for the liquid detergent extends in a ring around the receiving shaft 44. The receiving shaft 44 comprises on its wall in the direction of the free area the coupling device 46 in the form of the thread already mentioned.

The removal insert 108 is designed in such a way that it narrows the clear cross section of the outlet connector 104 to the smaller diameter of the central outlet opening 106. It has at its upper end centrally on the conical end wall 41 there the central outlet opening 106 and the lateral and circumferential coupling surface 109. A cylindrical section for connecting the riser pipe 110 is provided centrally adjacent to the outlet opening 106.

The storage tank 100 comprises the already mentioned outlet connection 104 with an external thread, which cooperates with the coupling device 46 of the lower partial shell 40, which is designed as an internal thread. The inner diameter of the outlet connector 104 is designed for clamping or latching connection to the removal insert 108 and its coupling surface 109.

In Fig. 8 shows in the form of an exploded sectional view a further embodiment of the metering store 10 according to the invention, which differs from the previous embodiment of the embodiment of FIG 5 to 7 differs. While there the upper partial shell 60 is formed in one piece from an elastically deformable plastic, in the exemplary embodiment that is Fig. 7 the upper partial shell 60 consists of a rigid support section 63 and an associated one formed elastic wall section 64, wherein the carrier section 63 is preferably made of a more rigid material than the wall section 64. The carrier section 63 is annular and comprises the plurality of outlet openings 62. In the present example, no holding structures 79 are provided in accordance with the previous exemplary embodiment. These could also be implemented in a variant of the second exemplary embodiment and are then preferably an integral part of the carrier section 63.

The lower partial shell 40 as well as the removal insert 108 and the storage device 100 are made in accordance with the exemplary embodiment Fig. 7 educated.

Fig. 9 shows an exploded sectional view of a third embodiment, in which the essential difference to the embodiment of Fig. 7 lies in the design of the pump chamber 70. While in the previous exemplary embodiments the entire interior 14 of the metering reservoir 10 forms the respective pump chamber 69, in this third exemplary embodiment only a partial region of the interior 14 is designed as a pump chamber 70.

This pump chamber 70 is primarily delimited by the upper partial shell 60, namely by a part of the deformable wall section 64 and a circumferential wall 72 attached to it and preferably integrally formed thereon and compressible in the pumping direction, which in the present case is in the form of a bellows. At its lower end, the compressible peripheral wall 72 has a sealing edge 74.

As in the previous embodiments, the lower partial shell 40 has, at an upper end of the receiving shaft 44, the filling opening 42 and the conical end wall 41 pointing towards the interior 14, which forms a sealing surface 50 for cooperation with the said sealing edge 74 of the wall 72.

Otherwise, the lower partial shell 40 as well as the removal insert 108 and the storage reservoir 100 are essentially identical to the exemplary embodiment in FIG Fig. 7 educated.

The 10 to 12 as well as 13 to 16 illustrate the exemplary embodiments in FIG 5 to 7 and FIG. 9 the mode of operation during a pumping process, which serves to suck detergent 105 into the receiving space 16 of the metering reservoir 10.

The 10 to 12 show the metering memory 10 from the first embodiment according to the 5 to 7 in cross section during the steps of the pumping process.

Here shows Fig. 10 the dosing reservoir 10 in the state already screwed onto the reservoir 100. The screens 48 already close the outlet openings 62, this having previously been achieved by screwing the metering reservoir 10 onto the storage reservoir 100. At the latest when a further rotational movement of the lower partial shell 40 with respect to the storage device 100 is no longer possible, a continued application of torque to the upper partial shell 60 has caused the relative rotation of the partial shells 40, 60 into the closed position during this turning.

The screens 48 are inserted into the holding structures 79 and are pressed by them against the outlet openings 62. The interior 14 is thus essentially insulated from a surrounding atmosphere.

Starting from the coupled state of the Fig. 10 the wall section 64, which serves as an actuating handle, is manually depressed from the outside. In Fig. 11 the metering accumulator 10 is shown with the wall section 64 elastically pressed in in the actuating direction 7. The interior 14 and thus the pump chamber 69 that it forms is thereby reduced. The excess pressure generated by reducing the size of the pump chamber 69 is transferred to the storage reservoir 100. If the actuating force is no longer present, the wall section 64 returns to its original shape and the volume of the pump chamber 69 increases again, a negative pressure being established in the interior 14.

In Fig. 12 illustrates this. The wall section 64 is returned to its original position, as a result of which the negative pressure formed in the interior 14 sucks the liquid detergent 105 out of the reservoir 100 via the riser pipe 110. The detergent 105 emerging from the filling opening 42 then runs into the receiving space 16 of the lower partial shell 40 due to the conical shape of the end wall 41.

13 to 16 show the embodiment of the Fig. 9 in cross section during the steps of the pumping process.

Fig. 13 shows the dosing reservoir 10 in the unactuated initial state, in which the dosing reservoir 10 is screwed onto the storage reservoir 100. By means of the panels 48 of the lower shell 40 are the outlet openings 62 of the upper partial shell 60 closed. The holding structures 79 press against the screens 48 from the interior 14. The lower partial shell 40 comprises the receiving space 16 for the liquid detergent 105. The upper partial shell 60 has the pump chamber 70, which in this state is open at the bottom, through the compressible peripheral wall 72 is limited and occupies only a portion of the interior 14. In the state of Fig. 13 this pump chamber 70 is not yet closed at its lower end, that is to say it is not insulated from the receiving space 16.

Fig. 14 shows how the wall section 64 is pressed in in the actuation direction 7, as a result of which the compressible circumferential wall 72 with its sealing edge 74 touches the sealing surface 50 of the receiving shaft 44 of the lower partial shell 40. As a result, the pump chamber 70 is isolated from the receiving space 16 and then volumetrically minimized in the course of the complete impression.

Fig. 15 shows an intermediate state during a return stroke movement, to which, during the transfer of the wall section 64 into its starting position, negative pressure in the pump chamber 70 leads to the liquid detergent 105 having been sucked into the pump chamber 70 from the storage device 100, the aspirated detergent 105 not yet Recording space has reached 16.

Fig. 16 shows the wall section 64 completely transferred into its starting position. In the transition from the state of FIG Fig. 15 in the the Fig. 16 the sealing edge 74 has come loose from the sealing surface 50, which is similar to opening a valve. As a result, the negative pressure breaks down and the detergent 105 runs in the direction of the arrows 9 from the pump chamber 70 into the receiving space 16 of the lower partial shell 40.

17 to 19 show the set of metering storage 10 according to the invention from the embodiment of FIG 5, 6 and 7 , such as 10 to 12 in cross section. However, this is only to be understood as an example. The other illustrated and described variants of the metering reservoir could also be part of such a set.

Fig. 17 shows the removal insert 108 pre-assembled on the dosing reservoir 10 and the riser pipe 110 before the dosing reservoir 10 is attached to the storage reservoir 100 for the first time. The removal insert 108 is non-positively held on a holding section below the end wall 41 of the receiving shaft 44.

Fig. 18 shows the first screwing of the dosing reservoir 10 onto the reservoir 100. The removal insert 108 is pressed into the outlet connection 104 of the reservoir 100. The holding force generated by friction is greater than the holding force generated by the holding section on the dosing reservoir 10, so that when the dosing reservoir 10 is subsequently unscrewed, the removal insert 108 remains on the outlet connector 104.

Fig. 19 shows the ready-to-use configuration of the metering reservoir 10 and the storage reservoir 100 achieved thereby. The removal insert 108 and the riser pipe 110 remain on the outlet connection 104 of the storage reservoir 100, wherein the metering reservoir 10 can be decoupled into a washing drum for dispensing liquid detergent 105.
