Definitions

  • 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.
  • a dosing store with an outer housing 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.
  • 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.
  • 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.
  • 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.
  • 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 can be filled particularly easily with metered amounts of a liquid detergent from the storage device.
  • 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.
  • 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.
  • the outer housing of the dosing reservoir can be partially transparent, so that a fill level can be recognized from the outside.
  • the outer housing has a measuring scale or a level marker having.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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.
  • the pumping chamber is operatively connected to the filling opening at least in phases, so that the negative pressure acts into the storage reservoir.
  • 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.
  • 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.
  • 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.
  • the cover 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.
  • 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.
  • the cover can be displaced by a switching element within the outer housing when coupling between the closed position and the open position.
  • the diaphragm changes between the closed position and the open position by displacing these housing parts with respect to one another.
  • the diaphragm can be closed by the actuation handle of the pump device while the pump device is actuated.
  • the at least one diaphragm can be designed in such a way that the outlet openings can be closed individually or in groups.
  • 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.
  • all diaphragms can be displaced together in order to switch between the closed position and the open position with one movement.
  • 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.
  • the diaphragm is preferably designed such that it closes the outlet opening essentially in an airtight manner.
  • the negative pressure generated in the pump chamber can be used to suck in the detergent.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the partial shells can be moved relative to one another between a first relative position and a second relative position in the coupled state.
  • 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.
  • 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.
  • 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.
  • this movement coincides with the movement of the pump actuation.
  • the diaphragm can be closed and the pump device can be actuated with just one actuation.
  • the partial shells can be rotated relative to one another.
  • the partial shells are in particular rotatable against one another about an axis of rotation.
  • the partial shells are preferably designed in the manner of hemispheres.
  • the partial shells occupy spherical segments of different sizes in the outer housing.
  • the individual housing parts have a mobility relative to one another which corresponds to the mobility of the partial shells described.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the metering accumulator 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.
  • this housing part can be rotated with respect to the supply store and thereby also with respect to another housing part.
  • 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.
  • 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.
  • 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.
  • the coupling device can also be the above-mentioned web or a groove.
  • 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.
  • 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.

  • the pumping device can be done by simply depressing the movable wall section.
  • 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.
