Definitions

  • the invention relates to a metering store according to the features of the preamble of claim 1.
  • a known metering reservoir (see US Pat. No. 2,941,309) is made as a spherical container from soft plastic. Small holes and slots are provided in the upper area of the metering reservoir, through which the laundry treatment liquid can escape. The effect is to be used that, when the ball is deformed by being pressed in or the like, the slots open and form an opening. There is also a ventilation opening in the lid of the dosing tank to replace escaping liquid with air. If the laundry treatment liquid escapes through the small openings and slots due to a deformation of the dosing reservoir, the known dosing reservoir is water for moistening laundry in a dryer, the water replacing air should be able to penetrate into the interior of the dosing reservoir through the ventilation opening.
  • the object of the invention is to improve the known metering reservoir and to make it more advantageous in use.
  • the bellows-like design according to the invention results in a predetermined indentation level, or possibly a plurality of predetermined indentation levels. At the same time, there is a structural reinforcement in the transverse direction to a folding or unfolding of the metering reservoir, which further enhances the desired effect of the predetermined folding level. It is also important that the bellows-like design results in a compression-like compression of the metering reservoir with a correspondingly resettable material.
  • the laundry treatment liquid is expelled from the metering reservoir during a compression process with pressure.
  • the dosing reservoir sucks in water, provided it is in the water.
  • the laundry treatment liquid in the interior of the dosing store is diluted and, in a subsequent compression process, laundry treatment liquid is immediately dispensed.
  • it is important that the opening through which the laundry treatment liquid exits during a compression process and also, if appropriate, water or alkali from the metering reservoir at the reset tion process is sucked in, is located in an essentially uninfluenced by the folding wall area of the metering.
  • the opening cross section of the opening is practically not influenced by the compression process of the metering reservoir.
  • the opening cannot be squeezed, for example if the compression is excessive. It is further preferably provided that the metering reservoir can be closed by a lid and the lid is stiffened in the wall region unaffected by the folding. This results in an advantageous support of the above-mentioned effect. It also supports compression in the preferred direction. It is also important that the arrangement of the cover in an uninfluenced wall area prevents the formation of a gap between the cover and the cover seat, for example due to corresponding stress on the wall area. However, the lid itself can be perforated in the sense of an outlet opening.
  • the cover can be opened during a compression process by means of an opening element arranged inside the metering dispenser in order to create the opening.
  • an opening element arranged inside the metering dispenser in order to create the opening.
  • This configuration enables an initially completely closed dosing container which only opens after the laundry treatment process has started, for example after the start of a washing process.
  • the reliable opening of the metering reservoir is made possible in combination by the bellows-like design, which enables the arrangement and reliable function of an opening element due to the preferred compression direction.
  • Such an opening element can be, for example, an opening mandrel, which is located in a bottom area of the metering reservoir, which is opposite the lid area.
  • the opening mandrel expediently extends essentially parallel to the direction of compression. The opening mandrel ensures, even under unfavorable conditions, that the metering reservoir no longer ver can close. With each compression process, the opening mandrel advances as far as is required in the specific design for opening the metering reservoir.
  • the metering reservoir is essentially spherical in cross section and that folds are formed in a region of the metering reservoir corresponding to a half-shell, which essentially surround the lid in a plan view in a circular manner.
  • the lid is advantageously arranged in a wall area unaffected by the folding.
  • the folds are formed in the upper half-shell receiving the cover.
  • the metering reservoir is elongated and can be compressed transversely to its longitudinal extent by a corresponding bellows-like design.
  • the dosing reservoir can have the shape of a tube.
  • the design is such that the dosing reservoir is essentially rectangular and / or polygonal in plan view and is designed as a substantially triangular body in side view, the base of the triangle being formed by the lid provided with holes serving as openings .
  • the lid various embodiments are available.
  • the cover can be designed essentially circular in plan.
  • the lid provides an advantageous resilience.
  • the cover in cross section in its outer vertical contour in is essentially semicircular.
  • the lid can also be tapered. In the end, the lid can be closed.
  • the contour is addressed, which results, for example, in the case of a medium cross-section through the cover in a plane approximately perpendicular to the compression plane.
  • the metering reservoir can also have an inward longitudinal fold, as described above, which not only enables an increase in volume but also a larger compression stroke with a compact design.
  • the opening or also the openings through which the laundry treatment liquid emerges during a compression process and, for example, during a subsequent resetting process, water or lye is sucked into the metering reservoir can initially be designed as a constantly open opening.
  • one or more flutter valves are arranged in this opening.
  • the valve can be designed such that the laundry treatment liquid is dispensed rapidly during a pumping process, but the reset is delayed. In this way, it can be achieved that maximum compression of the metering reservoir with a corresponding dispensing of laundry treatment liquid takes place only at certain time intervals.
  • Another alternative design of the dosing reservoir is characterized by a large number of folds and an essentially cylindrical shape of the dosing reservoir. This design provides a very large possible compression stroke. With regard to the lid, the shapes described above can be easily combined with such a design.
  • a further special design of the metering reservoir provides that it is formed from two hollow bodies which are essentially circular disk-shaped in plan and are arranged one above the other and that a circumferential, inward folding of the contact plane of the hollow bodies is formed.
  • Such a dosing store combines a relatively large stability outside its compression level with a large capacity with a very large possible compression stroke, based on the dimensions in the compression direction.
  • this dosing store but if possible to be combined with dosing stores of the types described above, it is provided that the opening is formed laterally to the cover.
  • the lid itself is not equipped with the function of the opening, which enables a correspondingly rigid shaping of the lid or a corresponding reduction in material.
  • an outlet opening sunk in relation to an outer cover surface or a surrounding outer wall area of the metering reservoir.
  • the emerging laundry treatment liquid does not come into direct contact with items of laundry in high concentration.
  • the opening cannot be blocked by a piece of laundry or in any case the exit of the laundry treatment liquid, for example, can be hindered by a piece of laundry looping around the dosing reservoir. Nevertheless, it may be of interest to delay the exit of the laundry treatment liquid and, as already mentioned above with regard to another embodiment, to reset the dosing reservoir after a pumping process.
  • an embodiment is advantageous in which an element that complicates the flow is arranged in the flow cross section of the opening. It can be an adapted sponge part.
  • the sponge part also has the particular advantage that the laundry treatment liquid emerges from the metering reservoir in a finely and evenly distributed manner.
  • the lid which is centered to the opening, can preferably be received by a nozzle-like holder that projects beyond the opening.
  • Another particular teaching of the invention relates to the use of a wave-like design of the metering reservoir to achieve a washboard effect. It has been found that the bellows-like design is not only advantageous for achieving a pumping effect, but also results in a considerable increase in the washing effect with such a configuration.
  • Dosing accumulators 1 are shown and described, which can be resettably pump-like compressed and changed by a bellows-like design in a preferred form.
  • the openings 2 for the outlet of the laundry treatment liquid or for the suction of air and / or lye are formed in a wall area of the metering reservoir 1 which can be substantially influenced by the folding.
  • the outlet openings 2 are formed in an upper, lid-like area, but in this embodiment a removable lid is not necessarily provided.
  • the upper region, in which the openings 2 are formed, and also the bottom region 3, which is formed symmetrically opposite thereto, are free of folds 4. Otherwise, the folds 4 are formed over the entire spherical shape in this embodiment.
  • the fold notches 5 run parallel to one another and essentially perpendicular to an axis passing through the middle of the upper and lower regions of the metering dispenser 1.
  • a dosing dispenser according to FIG. 1 or FIG. 2 can be deformed with a large pump stroke.
  • an opening mandrel 6 is provided in the bottom area 3 of the metering dispenser, which pushes open the cover 7 during a pumping movement.
  • the folds 4 are provided in this embodiment only in the upper hemisphere of the dispenser 1. This results in a greater stability of the lower hemisphere and thus a reliable alignment of the opening mandrel 6 on the cover 7.
  • the cover 7 can be opened to the outside and is in the open state outside the metering reservoir 1, but is permanently connected to it via a connecting tab 20.
  • the metering dispenser 1 is shaped as an elongated, bottle-like container which, in the illustration according to FIG. 5, has longitudinal folds 21.
  • the longitudinal folds 21 end at a distance in front of the cover 7 or the bottom 3.
  • the cover 7 is essentially circular in design and essentially semicircular in cross section in the compression plane.
  • this dosing store 1 also has a high compressibility with a large volume and a design that is highly compatible with laundry.
  • an opening of the cover 7, or in all openings, if several are provided can individual flap valves, not shown, may be arranged.
  • the flutter valves enable, for example, a delayed resetting of the metering reservoir 1 after a pump-out process.
  • the 7 is essentially tubular. 7 has an essentially triangular or polygonal shape, the base 9 of the triangle being formed by the cover 7. The result is a wedge-shaped cylinder or a wedge with a circular cross-section at one end.
  • the body can also be called a spherical section with a flattened base.
  • the outlet openings 2 are formed in the cover 7 of the embodiment according to FIG. 7 as channels which just pass through it.
  • the tip of the triangle is formed by a weld seam 10. From the further side view according to FIG. 8 it can be seen that this metering reservoir has a substantially rectangular shape in a plane perpendicular to the plane of the drawing in FIG. 7.
  • the cover 7 is essentially circular, which significantly supports the resilience of the metering reservoir according to this embodiment.
  • the dosing reservoir according to the embodiment shown in FIG. 9 is designed essentially rectangular in plan with rounded corners, where the contour of the cover 7 also has strongly rounded corners.
  • the bottom region 3 is shaped essentially in the same way.
  • the metering accumulator according to FIG. 9 has a retracted fold 4 at the sides with an overall relatively flat design.
  • the cover 7 has outlet openings 2 in the form of bores running parallel to the central axis 11. Out of the way 12 shows that the folds 4 and the inner fold notches 5 each have an extent corresponding to 1/5 of the radius.
  • the opening 13 is formed from two hollow bodies 12 which are essentially circular in the shape of a disk and are arranged flat one above the other.
  • a circumferential, inward folding 5 is formed in the plane of contact of the hollow body 12.
  • the fold 5 is drawn relatively far into the interior of the metering reservoir 1 according to FIG. 13.
  • the design of the opening 2 is particularly important in this embodiment.
  • the opening is annular and surrounds a nozzle 13 in which the cover 7 is held.
  • a sponge material, for example a foam material 14 is arranged in the outlet opening 2, which impedes the flow.
  • the connection of the connection piece 13 to the body of the metering reservoir 1 is realized via a bottom grille 15 which is also arranged in the opening 2 and likewise consists of plastic, like the rest of the metering reservoir.
  • the outlet opening 2 is inwardly offset with respect to the surrounding area of the metering reservoir, on the one hand the cover 7 and on the other hand the upper area of the wall 16.
  • the laundry treatment liquid only flows out through the sponge material 17. In the case of a resetting process, wash liquor or water is also sucked in only through the sponge material 14.
