Definitions
- the invention relates to a dosing store for receiving and dispensing a laundry treatment liquid in a washing machine according to the features of the preamble of claim 1.
- Dosing stores for receiving and dispensing a laundry treatment liquid have become known in various configurations. From US-T 993 001, for example, a metering memory is known, which is filled with a laundry treatment liquid and fed into a washing machine. The dosing reservoir is initially closed. During a certain cycle of the washing machine, the spin cycle, it opens due to a weight attached to the closure part. The centrifugal force overcomes the closing force of the lid.
- a metering memory which works on the same principle is also known from US Pat. No. 3,888,391. Furthermore, a metering memory is known from US Pat. No. 2,941,309, which has non-closable openings. The laundry treatment liquid can escape immediately at the beginning of a washing machine cycle or the like. Although this is fundamentally regarded as advantageous, this known dosing store has disadvantages in handling, in particular with regard to filling.
- the object of the invention is to provide a metering reservoir which is designed to be advantageous in use and is constructed as simply as possible.
- the liquid can also escape without the drum movement having started.
- the dosing store in question is, for example, water which is added to the laundry for moistening in order to set a suitable ironing moisture.
- dosing stores are not yet satisfactory in every respect.
- the spin cycle the laundry treatment liquid cannot be added immediately after the laundry treatment has started.
- dosing stores that are always open are not satisfactory in every respect. Even with slight tilting or the like, laundry treatment liquid can escape without the washing machine operation having started. A defined fill level is sometimes also missing when filling. It is easier for laundry treatment liquid to overflow when filling.
- the object of the invention is to provide a metering reservoir which is designed to be advantageous in use and is constructed as simply as possible.
- the dosing store according to the invention is initially closed, but opens immediately at the beginning of a laundry treatment in a washing machine. It has an openable closure which is formed by a liquid-carrying closure body which, when the metering reservoir is full, bears against the outlet opening provided with an adapted seal.
- the closure body is also located in a cage inside the metering reservoir. The cage tapers like a dome towards the outlet opening.
- the closure body for example a floating ball, is located on the bottom of the dosing reservoir.
- the floating ball rises with the liquid level of the laundry treatment liquid in the cage.
- the floating closure body is guided to the outlet opening by the dome-like taper.
- the cage is funnel-shaped, in a quasi-reverse orientation.
- the neck area In the filling position of the dosing reservoir, i.e. in the normal, vertical position, the neck area is at the top and the funnel opens downwards.
- the neck area is assigned according to the outlet opening.
- the neck region has a diameter slightly exceeding the diameter of the closure body or, if need be, a diameter equal to this.
- the sealing ring In the neck area, assigned to the outlet opening, there is a sealing ring, against which the closure body, that is to say the floating ball, comes into contact when it is filled.
- the sealing ring is arranged displaceably in the neck area.
- the metered amount of laundry treatment liquid in the metering memory can be varied in a simple manner. For example, between a 120 ml dose and a 180 ml dose. It is also preferred that, according to the manufacture, the sealing ring is in the position which is assigned to the larger dosing volume, that is to say approximately the 180 ml volume. The dosing ring can then be shifted downward by the user into the position corresponding to the smaller dosing volume, it being expedient that the user does not make any further shift is possible.
- the alternative to a sealing ring arranged displaceably in the area of the cage is provided that the cage is arranged so as to be displaceable overall in the interior of the metering reservoir and that the neck area with a sealing ring formed therein - fixed relative to the neck area - telescopically with a guide neck pushed against the outlet opening cooperates.
- the mobility of the cage as a whole to change the metered amount enables a larger change in the metered amount with a smaller displacement path.
- the cage as is also regarded as a special embodiment, is designed to be closed, while, in the case of the displaceability of only the sealing ring, as described above, the cage can also be perforated in its funnel-shaped area.
- the metering reservoir With regard to the external design of the metering reservoir, it can be provided that it forms an approximately pear-like contour. In combination with the funnel-shaped, open cage, this results in a relatively small volume between the cage wall and the wall of the metering reservoir.
- the dosing reservoir can also be egg-shaped in its contour, which, in combination with the cage described, results in a larger volume between the outer cage wall and the inner wall of the dosing reservoir.
- the metering reservoir has flattened areas in all of the lower areas that serve as a base. Inside the dosing reservoir, the cage preferably runs into the dosing reservoir wall in its lower extension area above the dosing reservoir bottom. This is preferred in the area of the largest diameter of the metering reservoir, so that the cage is (also) held in a form-fitting manner in this area.
- the hollow body-shaped dosing reservoir has a closure body arranged therein, which has outlet openings on its outer circumference and reduces the filler opening cross-sectional area when the dosing reservoir is full.
- the closure body is preferably a buoyancy body.
- the outlet openings in the closure body are at least partially connected to one another and to the interior of the container.
- the dosing reservoir can easily be filled with liquid detergent.
- the cross-sectional area of the filling opening is sufficiently reduced when the dosing reservoir is full due to the closure body, which floats against the opening by floating on the liquid detergent, for use of the dosing reservoir in a washing machine, and after being introduced into the washing machine, the liquid detergent can emerge evenly and in a metered manner through the outlet openings during the washing process.
- the container space wall surface delimiting the filling opening and / or the filling opening for receiving the closure body or buoyancy body are designed to be adapted to its spatial shape, in particular to its surface geometry. This configuration ensures that the closure body can lie closely against the opening.
- the buoyancy body when the metering reservoir is full, preferably projects in some areas into the filling opening and essentially closes it against the inner surface of the container space.
- the invention further provides in a preferred embodiment that the container interior wall surface, starting from the inside end of the opening, runs in the form of a spherical layer, that is to say a spherical surface, onto a cylindrical container wall area and the buoyancy body is designed as a ball with a surface corresponding to this area of the interior wall of the container.
- the buoyancy body is a hollow body with a central cavity and the outlet openings connected to it gene is formed. Furthermore, in order to ensure a connection between the interior of the container and the filler opening at all times, it is expedient that the outlet openings are evenly distributed on the surface of the buoyancy body. For a uniform floating of the buoyancy body, it is advantageous that the cross-sectional area of the buoyancy body is slightly smaller than the free cross-sectional area available within the container for the buoyancy of the buoyancy body.
- the invention provides that the buoyancy body consists of material of lower density than the liquid detergent, in particular polystyrene or cork.
- the filling volume of the container can be changed, for which purpose, according to a further embodiment, two container parts delimiting the filling volume are designed such that they can be shifted relative to one another. It is expedient here that a container part is essentially cylindrical and a container part is cup-shaped. To set a desired filling volume, the invention further provides that the container has markings on the outside to indicate the filling volume.
- the container has a thread or locking means in the head region.
- the container can be connected to a bottle containing the liquid detergent and thus simultaneously act as a closure cap and metering device.
- the device according to the invention is uncomplicated and user-friendly to handle and can be inserted easily and simply into a washing machine drum. It is placed on or between the laundry in the washing machine drum placed and then the washing process started. During the washing process, the detergent gradually and evenly emerges from the container; after the washing process has ended, the dosing reservoir is completely empty.
- the dosing container is designed in two parts, and the closure body, designed as a buoyancy body, projects above the upper edge of the dosing reservoir when filled, whereby it is guided in a cage projecting vertically into the interior of the dosing reservoir.
- the buoyancy body After filling the dosing reservoir and placing the upper housing part with the buoyancy body, the buoyancy body lifts upwards by immersing the cage in the laundry treatment liquid.
- the buoyancy body is driven upwards by further immersing the cage in the laundry treatment liquid until it closes the opening of the metering reservoir. In this closed state, the dosing reservoir can be inserted into the washing machine.
- the buoyancy body is preferably cylindrical in its lower region and essentially egg-shaped in its upper region. In the filling state, the egg-shaped area protrudes correspondingly beyond the upper edge of the metering reservoir.
- the laundry can then exert pressure on this egg-shaped area at the start of the washing process in order to press the buoyancy body inwards into the metering reservoir and thus (partially) clear the outlet opening.
- the closure body further preferably has an extension which is approximately half the height of the Dosing memory corresponds.
- the diameter of the closure body corresponds to at least half the diameter of the dosing reservoir.
- a dosing reservoir 1 which has an inner cage or dome-like insert 2 and a closure body 3, which is preferably designed as a floating ball.
- the cage 2 has a funnel-shaped area 4 and a neck area 5.
- the funnel-like cage 2 is arranged with the opening of the extension area facing downward in the metering reservoir 1.
- the cage 2 tapers toward the outlet opening 6 which is formed in the upper region of the metering reservoir 1.
- the closure body 3 is thus carried by the liquid upwards towards the outlet opening 6 when the metering reservoir 1 is filled.
- a sealing ring 7 is arranged in the neck area 5 of the cage 2 and can also be provided, for example, as a sealing bead formed in one piece with the neck area.
- the sealing ring 7 is designed as a separate part and is displaceable in the neck region 5 of the cage 2. This is shown, for example, in FIG. 5. Due to the displaceability and a corresponding length of the neck area 5, the. Dosing quantity can be reduced to 2/3, for example.
- a stop bead 22 is provided in the upper area and two locking beads 23 are provided in the lower area.
- the sealing ring 7 is located above the locking rings 23.
- the floating and entering the neck area of the cage 2 float ball 3, the sealing ring 7 is then carried upwards until it rests on the locking bead 22.
- the sealing ring 7 can be pressed through the opening 6 by hand, for example, between the two locking beads 23.
- the neck area 5 of the cage 2 is otherwise formed with a diameter slightly exceeding the diameter of the closure body 3, so that the closure body 3 can move freely in the neck area 5 when the metering reservoir 1 is filled, until it rests on the sealing ring 7.
- the dosing reservoir shown in FIG. 1 is shown in the filling state. Since the cage 2 is closed-walled and abuts the outer wall 9 of the metering reservoir 1 at 8, the filling volume is limited by the cage volume 2 and the volume formed below the cage by the wall region 10 of the metering reservoir 1.
- a cage 2 which is displaceable overall in the metering reservoir 1, is shown.
- the neck area 5 with a sealing ring 7 formed therein - is telescopically guided in a guide socket 11, which is connected to the outlet opening 6.
- the cage 2 can be locked by means of corresponding locking projections on the inner wall of the metering reservoir 1 in the position according to FIG. 3 or FIG. 4 (exaggerated in the drawing for clarity).
- the cage 2 is perforated.
- the embodiment according to FIG. 5 shows the metering reservoir 1 with a perforated cage 2 in the empty state. 6 the same in the filled state.
- the representation according to FIG. 7 represents the dosing reservoir 1 during a washing treatment, filled with laundry treatment liquid, in a position tilted by the wobble movement.
- the wall of the cage 2 runs into the dosing storage wall in its lower extension area above the dosing storage base 12.
- the inlet point is located approximately in the area of the largest inner diameter of the metering reservoir 1, so that the cage 2 is positively held in the metering reservoir 1.
- the metering stores 1 shown have a flattening 13 serving as a standing surface in their lower region.
- FIG. 10 likewise shows a hollow body-shaped metering reservoir, designated overall by 1.
- the metering reservoir 1 consists of a cylindrical container part 18 and a cup-shaped container part 19.
- the cylindrical container part 18 In its upper region, the cylindrical container part 18 has a single opening 6, which is delimited by container wall regions 14 tapering from the cylindrical side wall regions 15 to the main axis 24 of the container. Outside the spherical layer-shaped container wall areas an internal thread 21 is formed in a cylindrical extension 25 of the cylindrical wall regions 15.
- a spherical buoyancy body 3 is arranged in the hollow body-shaped metering reservoir 1 and has outlet openings 17 on its outer circumference that are distributed substantially uniformly over its outer surface.
- the outlet openings 17 are connected to the central interior 16 of the buoyancy body 3 designed as a hollow ball and thus also to one another.
- the radii of the inner surface of the spherical layer-shaped container wall 14 and the surface geometry of the spherical buoyant body 3 are coordinated with one another such that when the metering reservoir 1 is filled, the buoyant body 3 preferably projects in regions into the individual opening 6 and essentially closes it, closely closing the inner surface of the container wall regions 14 creates.
- the radius D of the spherical buoyancy body is slightly smaller than the diameter d of the cylindrical container part 18, so that the corresponding cross-sectional area of the buoyancy body 3 is slightly smaller than the corresponding free cross-sectional area available within the metering reservoir 1 for the buoyancy of the buoyancy body 3.
- the buoyancy body 3 consists of styrofoam. However, it can also consist of cork or another material of lower density than the liquid detergent used.
- the cylindrical container part 18 and the cup-shaped container part 19 are designed such that they can be pushed into one another, as a result of which the filling volume of the doser store 1 can be changed. In the overlap region 26 between the container parts 18 and 19, these can be locked in different relative positions with respect to one another by latching means. The locking means are not shown here.
- 19 marks 20 are embossed on the outside of the cup-shaped container part to indicate the respectively set filling volume.
- the metering accumulator 1 consists of a flexible, deformable plastic which springs back into its original shape when external forces are removed.
- the dosing reservoir 1 is filled with liquid detergent through the filling opening 6 until the buoyancy body 3 becomes visible in the filling opening 6 and thus indicates to the user that the filling process should be ended. In this position, the buoyancy body then also lies closely against the filling opening and essentially closes it. Then the metering memory 1 is placed in the drum of a washing machine and the washing process is started. During the washing process, the liquid detergent then emerges from the metering reservoir 1 into the washing machine through the outlet openings 17. After the washing process has ended, the empty dosing reservoir 1 can then be screwed onto the bottle of the liquid detergent with the screw thread 21 and thus take over the function of a closure cap.
- the exemplary embodiment described can also be modified to the extent that the metering reservoir 1 does not necessarily consist of two container parts 18 and 19 which can be displaced relative to one another, but consists of one or two container parts which only delimit a defined filling volume.
- the buoyancy body can be cylindrical, cuboid or the like.
- the buoyancy body 3 is held in a cage 27 which has a lower inlet opening 28.
- the cage 27 is integrally formed on the spherical shell-shaped wall regions 14, while leaving a distance from the container part 18.
- the container parts 18 and 19 are connected to one another by means of a thread 28. It different volumes, indicated with "A” and "B", can be set.
- the closure body 3 consists of a buoyancy body which is cylindrical in its lower region 29 and essentially egg-shaped in its upper region 30.
- the egg-shaped region 30 projects beyond the upper edge 31 of the metering reservoir 1.
- the container part 18 is connected at 32 by means of a thread to the lower container part 19.
- the cage 27 is molded onto the upper container part 18, near the outlet opening 6.
- the closure body 3 has an extent which corresponds to approximately half the height of the metering reservoir 1.
- the diameter of the closure body 3 corresponds to at least half the diameter of the metering reservoir 1.
- the volume 35 which is formed between the container wall 33 and the outer wall section 34 and is detergent-free even when filled, even results in a certain floating effect, for example in a washing machine filled with detergent solution.
