Definitions

  • the invention relates to a metering memory according to the features of the preamble of claim 1.
  • a known dosing store (see US Pat. No. 2,941,309) is made as a spherical container from soft plastic.
  • small holes and slots are provided 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 up and form an 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 memory, which further enhances the desired effect of the predetermined folding level. It is also important that the bellows-like design results in a pump-like compression of the metering reservoir with a correspondingly resilient material.
  • the laundry treatment liquid is expelled from the metering reservoir with pressure during a compression process.
  • the dosing reservoir sucks in water insofar as 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 again dispensed immediately.
  • the opening cross section of the opening is practically not influenced by the compression process of the metering reservoir. It cannot become one
  • the metering reservoir can be closed by a lid and that the lid is arranged stiffening in the wall area 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 means that a gap cannot form between the cover and the cover seat, for example due to a corresponding stress on the wall area. However, the cover itself can be perforated in the sense of an outlet opening.
  • the cover for creating the opening is revealed by an opening element arranged in the interior of the metering dispenser during a compression process.
  • 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 through 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 compression direction. The opening mandrel ensures, even under unfavorable conditions, that the dosing reservoir no longer gets lost 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 dosing reservoir is essentially spherical in cross section and that folds are formed in a region of the dosing reservoir corresponding to a half-shell, which top view of the lid essentially surrounded in a circle.
  • the folds are formed in the upper half-shell receiving the cover.
  • the dosing reservoir is elongated and can be compressed transversely to its longitudinal extent by a corresponding bellows-like design.
  • the metering reservoir can have the shape of a tube.
  • the design is such that the dosing reservoir is essentially rectangular and / or many kig in plan view and is designed in the side view as an essentially triangular body, the base of the triangle being represented by the as Holes serving openings are provided with a lid.
  • the lid various embodiments are available.
  • the cover can have an essentially circular shape in plan. In combination with the tubular design of the dosing reservoir, this results in
  • 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. In this case, the contour is addressed, which results, for example, in the case of a central cross section through the cover in a plane approximately perpendicular to the compression plane.
  • the metering reservoir can also have an inward longitudinal fold with the elongated design T 1 described above, which not only enables an increase in volume but also a larger compression stroke with a compact design.
  • the opening or the openings through which the laundry occurs aus ⁇ treatment liquid in a compression process, and is sucked as in a subsequent reset operation water or brine in the dispenser may be initially formed as a constantly open orifice.
  • one or more flutter valves are arranged in this opening. The valve can be designed such that the laundry treatment liquid is dispensed quickly during a pumping process, but the reset is delayed. In this way it can be achieved that maximum compression of the dosing 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 forms 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 in the shape of a plan and are arranged one above the other and that a circumferential, inwardly directed fold 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.
  • 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. It is further preferred to arrange such an outlet opening sunk in relation to an outer surface of the cover or a surrounding outer wall area of the metering reservoir.
  • the emerging laundry treatment liquid does not come into direct contact with laundry items in high concentration, provided that the dosing reservoir is already in the water or in the alkali.
  • 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 prevented by a piece of laundry looping around the dosing store. 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, for example. The sponge part also leads to the particular advantage that the laundry treatment liquid exits the metering reservoir in a finely and evenly distributed manner.
  • the lid which is located in the middle located to the opening, is preferably receivable by a stutzenarti gene, the opening projecting bracket.
  • Another, particular teaching of the invention relates to the use of a wave-shaped 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 in such a configuration. In view of this, it may be advisable to design the dosing reservoir also with a bellows configuration with a relatively rigid wall, without a pump effect occurring. It may also be advisable to shape only areas of the bellows-like design so softly that pumping compression is possible, but to provide a further area with a relatively rigid wall structure.

Abstract

Un doseur de réception, de stockage et de distribution d'un produit liquide de traitement du linge dans une machine à laver ou similaire comprend un orifice de remplissage et au moins un orifice distributeur du produit liquide qui coïncide éventuellement avec l'orifice de remplissage, le doseur étant élastiquement déformable. Afin d'obtenir un doseur amélioré, notamment plus avantageux du point de vue de son utilisation, le doseur (1) présente au moins en partie la forme d'un accordéon pouvant être comprimé de manière réversible de façon à pouvoir réduire son volume et prendre une forme prédéterminée préférée. L'orifice (2) est ménagé dans une région de la paroi du doseur essentiellement non susceptible d'être affectée par la compression de celui-ci.
