Definitions

  • the invention relates to a metering memory according to the generic features of claim 1.
  • Dosing stores for receiving and dispensing a laundry treatment liquid are 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 closure force of the cover.
  • 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.
  • the dosing store in question is, for example, water as the laundry treatment liquid, which is added to the laundry for moistening in order to set a suitable ironing moisture.
  • the known dosing stores are not yet satisfactory in every respect. With dosing tanks, which are only in open a certain cycle of a washing machine, the spin cycle, the laundry treatment liquid can not be added immediately after the start of the laundry treatment. On the other hand, with metering stores that are always open, it is sometimes found to be unsatisfactory that the laundry treatment liquid can also escape before a laundry treatment cycle has started. If, for example, longer downtimes precede, it is possible for highly concentrated laundry treatment liquid to flow onto items of laundry and to cause color fading or the like.
  • the known metering reservoir which only opens during a spin cycle, is also designed to be relatively complex.
  • the object of the invention is to provide a metering reservoir which is of more advantageous use and is constructed as simply as possible.
  • the dosing store according to the invention is initially closed, but opens immediately at the start of a laundry treatment.
  • the opening of the pump-like, compressible configuration of the metering reservoir works together with the closing part that can be lifted off by pressurization. As soon as the laundry treatment liquid is pressed against the closing part from the inside with pressure, the closing part lifts off and forms an exit gap or the like.
  • the metering accumulator is at least partially designed like a bellows and that the opening is located in an area of the metering accumulator that is not influenced by the bellows-like configuration.
  • the closure part is advantageously stiffened in the wall area unaffected by the folding.
  • the outlet openings are formed in the lid area and can be covered by a closing part connected to the lid.
  • the outlet openings or a single outlet opening can be formed in the cover itself.
  • a membrane molded onto the lid or connected to it can, for example, cover the outlet opening and open when pressurized.
  • the outlet openings can also be designed to surround the cover, covered by a membrane connected to or molded onto the cover.
  • the cover can be unscrewed, which at the same time also exposes the outlet openings, at least when the outlet openings are formed surrounding the cover.
  • the laundry treatment liquid can then simply be introduced through a large opening with the cover removed. After the outlet opening has been closed by means of the cover, the laundry treatment liquid can only emerge from the metering reservoir when pressure is applied.
  • the pump-like configuration of the dosing reservoir can be set such that laundry treatment liquid only emerges from the dosing reservoir at a pressure that can be caused by wet laundry items.
  • the dosing store according to the invention makes it possible to put one filled with laundry treatment liquid into the washing machine, whereupon the laundry treatment liquid only emerges from the dosing store at the beginning of a washing cycle. Accidental tipping or falling over of the filled dosing reservoir in a washing machine without the laundry treatment cycle having started does not necessarily lead to the leakage of the laundry treatment liquid.
  • the closure area for the cover is formed on the metering storage wall by means of webs and that the openings are formed between the webs.
  • Another metering memory which advantageously only releases the laundry treatment liquid after the start of a laundry treatment cycle, that is to say has a closure that can be opened during the laundry treatment, is characterized in that the opening is closed in a closed state by an erect rocker arm closure.
  • the rocker arm lock When the rocker arm lock is upright, the rocker arm extension projects freely over an upper area of the metering reservoir.
  • a tilting moment is exerted on the upstanding area of the rocker arm, which flips the rocker arm and then releases the opening according to the invention.
  • this rocker arm accordingly opens up a filling opening which also serves as an outlet opening during operation of the washing machine.
  • the laundry treatment liquid is poured in when the rocker arm is upturned, the rocker arm is then raised and the dosing reservoir is inserted into the washing machine with the rocker arm upright.
  • the rocker arm as already described, is flipped over by the laundry pressure and thus the outlet opening is released.
  • the opening can be closed by a cover which is caught and can be lifted off the dosing store.
  • the lid When the lid is lifted, there are liquid exit paths for the laundry treatment between the lid, in particular its fastening area and the edge area of the dosing storage container, in particular the fastening edge of the dosing storage container open.
  • An advantageous embodiment is characterized in that the cover can be screwed on without a stop, such that the cooperating threads can be disengaged when screwed on.
  • the lid has approximately an edge area which has a cylindrical longitudinal extent. Only at the front, open edge of the cylindrical region are threads formed on the inside, which interact with corresponding threads on the edge of the metering storage container.
  • two threads lying one above the other are formed on the edge of the lid and on the edge of the metering storage container.
  • the cover falls off after the two threads have been turned. It can then stand out by a certain amount during the laundry treatment cycle. As long as it is not turned, the threads act as a lock that prevents it from lifting off completely. It is not necessary to have threads on the cover. For example, two or four cams distributed over the circumference are sufficient.
  • the cover forms a sealing edge in the area in which it sits on the metering storage container when it is screwed on. If necessary, this sealing edge can also be assigned a certain latching action, so that a slight tilting or the like of the metering reservoir in a washing machine before the laundry treatment cycle begins does not yet allow laundry treatment liquid to leak.
  • Another dosing reservoir according to the invention with a closure that can be opened during laundry treatment is characterized in that the closure is formed by a lid-lockable cage that is movably caught in the dosing reservoir and projects into the interior of the dosing reservoir and forms openings.
  • the lid-lockable cage is caught in an opening of the metering reservoir by means of lower and upper stop areas which project beyond the opening.
  • the lower stop area of the cage can be a spring hook be.
  • the upper stop area also serves as a sealing edge for the lid.
  • the lid is opened with the cage protruding into the interior of the dosing reservoir. Because of the large opening, the laundry treatment liquid can easily be filled in.
  • the lid is then closed and the dosing reservoir is inserted into a washing machine, for example.
  • the cage moves outwards when the dosing reservoir has its opening pointing downward.
  • the laundry treatment liquid can then - in a metered manner - escape through the openings formed in the edge walls of the cage.
  • the metering reservoir is at least partially bellows-like in this embodiment. In this case, the features described further above in relation to the bellows-like configuration can also be additionally implemented.
  • the closure portion rests spring-loaded on the opening in the case of a closing part lying on the outside, which can be lifted off by pressurization and an at least partially bellows-like configuration of the dosing reservoir.
  • the spring can advantageously be designed as a snap spring. After overcoming a certain opening pressure acting on the closure part, the closure part is in a stable opening position, which can only be reversed into the closed position by overcoming the snap spring pressure.
  • a spherical body is advantageous as a closure part.
  • a further dosing store according to the invention for receiving and dispensing a laundry treatment liquid in a washing machine or the like, which has a closure which can be opened during the laundry treatment, is characterized through an outlet opening, which is formed at a lower level, below a liquid level of the filled dosing reservoir, than the inlet opening. Furthermore, the outlet opening can be closed from the inside by means of a liquid-carrying closure body. When this dosing reservoir is filled, the liquid-carrying closure body moves into a closed position. Because the filling level is above the opening level of the outlet opening, the outlet opening is securely closed by means of the closure body.
  • the outlet opening to the inside of the metering reservoir is advantageously designed in such a way that when the metering reservoir is pivoted or tilted or tipped over, the liquid-borne closure body can release the outlet opening.
  • This configuration can be essentially funnel-shaped, for example.
  • the closure body is advantageously a floating ball, the weight of which is set approximately such that it only protrudes above the liquid level in its upper region. The contact pressure in the closed state can be adjusted by the weight of the floating ball.
  • the dosing reservoir in particular in this embodiment, forms two chambers which are connected to one another by one or more liquid channels. The closure body, such as the floating ball, can thus be caught in the chamber having the outlet opening.
  • the closure body cannot penetrate into the chamber having the filling opening and can be lost through the filling opening.
  • the arrangement of the inlet opening and the outlet opening at different levels, namely the outlet opening corresponds to a lower level than the filling level of the filled dosing reservoir, is also associated with the advantage that the closure body can already take a sealing seat at a relatively low filling level.
  • the outlet opening is released on.
  • the outlet opening is covered by a perforated cap.
  • the arrangement of the inlet opening and outlet opening at different levels initially results in an approximately graduated design of the metering reservoir.
  • the perforated cap which extends over the outlet opening, can complement the outer shape of the metering reservoir to a desired round shape or the like.
  • the perforated cap extends over the outlet opening at a distance from the outlet cross section and the opening edge. Leaking laundry treatment liquid thus enters, as it were, first into a further chamber which is still formed in the metering reservoir, in which mixing and dilution with the water which has flowed in can take place and only then completely emerges from the metering reservoir through the perforated cap.
  • the metering reservoir has an approximately central constriction which leaves the liquid channel, or else a plurality of liquid channels.
  • the perforated cap can be formed together with an area which closes the filler opening like a lid and is connected to the perforated cap by a film hinge.
  • the perforated cap itself can be fastened to the metering reservoir by means of a retaining web. Operationally, it is possible to fold up the area closing the filler opening for filling, while the perforated cap area is operatively connected to the metering reservoir.
  • the closure part is a floating body trapped in the cage.
  • This configuration is also important with regard to the above-described metering reservoir, since the chamber receiving the closure part described can also be understood in this sense as a cage.
  • the closure member is a buoyant or at least liquid-borne body
  • the closure member is a submersible body. Because of its weight, the submersible body closes an opening suitably formed in the lower region of the cage. By suitable design of the cage, the closure body can be removed from the opening for filling when the metering reservoir is tilted.
  • the closure body releases the opening in the case of tilting positions or head overlays of the metering reservoir for the exit of the laundry treatment liquid.
  • the cage is funnel-shaped, at least in its lower area, which has the opening.
  • the upper area of the cage which can essentially represent the upper area of the metering reservoir at about the same time, can be formed, for example, by a lattice construction which exposes a series of outlet openings.
  • the laundry treatment liquid first enters an intermediate chamber, as it were, before finally, very often in an advantageously diluted form, it leaves the metering reservoir completely.
  • the outlet opening can be closed by a closure plate anchored to the metering reservoir and pretensioned on a sealing edge.
  • the preload can be created by the pump-like compressibility of the metering reservoir itself.
  • the anchoring is preferably formed on the dosing storage base.
  • the sealing edge which cooperates with the closure plate, can be displaced by the at least partially bellows-like configuration of the metering storage wall for opening the outlet opening, and an area of action of the metering storage wall is designed to project radially beyond the sealing edge.
  • the area of application is approximately one fold of the folds bellows-like design of the metering storage wall.
  • the radial projection of the sealing edge enables items of laundry or the like to have a compressive effect on the area to be acted upon.
  • the design creates a simple possibility for opening the outlet area, which is integrated into the functional design of the metering reservoir.
  • the closure plate is molded onto a filling cylinder which penetrates the metering reservoir and is anchored in the bottom of the metering reservoir and has through openings.
  • the filling cylinder which is firmly connected to the bottom of the dosing reservoir, extends through the dosing reservoir and forms an upper edge which forms the closure plate.
  • the dosing reservoir or the closure plate can be closed by means of a hinged lid.
  • the filling cylinder preferably has through openings distributed over its length.
  • the filling cylinder which interacts with the sealing edge of the metering reservoir wall, gives the metering reservoir a certain degree of stability.
  • the area of interaction of the closure plate with the sealing edge of the metering storage wall can also be designed such that the metering storage wall is trapped - displaceably - in the sealing plate and, when the sealing edge is pressed down, openings formed in the sealing edge are free which allow the laundry treatment liquid to pass through. When the pressure drops, the openings slide back into the locking plate so that the metering reservoir is closed.
  • a further dosing store for receiving and dispensing a laundry treatment liquid in a washing machine or the like, which likewise has a closure that can be opened during the laundry treatment, is provided according to the invention with a closure part that can be inserted like a stopper into an opening, the insert that can be inserted into the opening for Forming a plug seat serving plug area has a short length and the closure part has a cantilevered handling area to form an opening-tilting moment.
  • the closure part is removed from the stopper seat and laundry treatment liquid is poured in. Then the closure part is firmly inserted, which is easy to carry out due to the necessary relatively large handling area, which can be approximately spherical.
  • the dosing reservoir with the stuck closure part is inserted or inserted into the washing machine as usual. After the start of the laundry treatment cycle, in particular due to the forces exerted by damp laundry items, there is a tilting moment on the handling area of the closure part, which is thereby removed from its closure seat. The closure part can then be completely separated from the remaining metering reservoir, or can still be connected to it via a cord or the like.
  • the invention proposes that the locking plate be attached to the dosing reservoir such that it can move and has a handling extension that serves to form an opening force.
  • the closure plate can thus be deflected from its closed position, for example again by pressing laundry items onto the handling extension, whereupon it closes again when the pressure is released.
  • the closure plate for filling the dosing reservoir can be deflected accordingly.
  • the pendulum-like suspension or mounting of the locking plate can be realized, for example, by means of a pendulum rod anchored in the metering storage base be based.
  • the handling extension of the closure plate is designed to be divisible, with a lid-like upper part. For example, filling is possible without deflection of the closure plate. By securely latching the lid, it can be ensured that during the washing cycle, laundry treatment liquid only occurs due to a deflection of the closure plate via the pendulum-type mounting, not by opening the lid.
  • the handling extension itself can be spherical.
  • it can further be provided that it is rotatably mounted on the outside of the metering reservoir by means of a mounting bracket.
  • the locking plate can be moved into the closed position and into an open position as if it were a visor.
  • the bearing can also be created in such a way that there is no restoring torque with regard to a closure.
  • Another dosing reservoir according to the invention with a removal opening and an outlet opening that can be opened during the laundry treatment, in which the outlet opening is also formed at a lower level than the inlet opening, below a liquid level of the filled dosing reservoir, is characterized in that an inside of the dosing reservoir the outlet opening leading overflow is formed.
  • the dosing reservoir which is filled, for example, via a latch-lockable lid closure, has approximately an outlet opening, which has an overflow of an inner vessel, which contains the laundry treatment liquid is filled, is in connection.

  • Another dosing reservoir in the context of the present invention with a closure that can be opened during the laundry treatment is characterized by an area drawn into the interior of the dosing reservoir with an outwardly projecting cage that closes at the top and forms side openings, the cage having a surrounding cage that faces upwards a locking position interchangeable locking part cooperates.
  • the closure part When the closure part is pressed down or pushed down, the openings of the cage protrude beyond the sealing edge of the closure part, which cooperates with an upper sealing edge of the cage, so that the laundry treatment liquid can escape freely through these openings to the outside.

  • the over-dead center snap action of the spring 35 achieves a secure closed position.
  • a pump-like compression is achieved by the action of the laundry pressure, which compresses the ball 34 into the open position shown in dashed lines.
  • the spring 35 for the ball 34 which can consist of several spring struts, is in the rest held in a cap 37 which overlaps the upper region of the metering reservoir 1. This cap 37 is designed essentially in accordance with the cap in the metering reservoir 1 according to FIG. 6.
  • the opening 8 has a first chamber 38 and a second chamber 39, which are separated from one another by separating webs 40 which leave liquid channels 41.
  • the opening 5 which can be closed by the closure body 42, is arranged at a lower level than the filling opening 43, which is formed in the second chamber 39 on the right in FIG. 8.
  • the opening 5 and the filling opening 43 are overlaid by a cap 44, which is fastened to the metering reservoir 1 by means of a retaining web 45.
  • the closure area 46 of the cap 44 can be opened by means of a film hinge 47, while the cap area 48 cannot be removed from the metering reservoir 1 during operation.
  • the cap area 48 is arranged at a distance from the opening 5 and a wall area 49 of the metering reservoir 1 surrounding the opening 5, so that an intermediate space 50 is formed. Furthermore, outlet openings 51 are formed in the cap 48. Laundry treatment liquid emerging from the opening 5 thus first reaches an intermediate chamber before it leaves the metering reservoir 1 completely. As can be seen in particular in FIG. 10, the separating webs 40 can be formed by constrictions in the metering reservoir 1. To fill the metering reservoir 1 according to FIGS. 8 to 10, the cap area 46 is pivoted about the film joint 45, so that the filling opening 43 is free.
  • Laundry treatment liquid is poured in through the filling opening 43, whereupon the ball 42 floats on the liquid level and, due to the funnel-shaped design of the section 49, migrates up to the opening 5 when it is filled and closes it. Because the filling opening is arranged at a higher level than the opening 5, the opening 5 is sealed even at a relatively low filling level.
  • the cap area 46 is closed and the metering reservoir 1 is inserted into the washing machine. Due to the wobbling movement, the floating ball 42 is removed from the Opening 5 is torn away and so laundry treatment liquid can escape from the metering reservoir 1.
  • the floating ball 42 can be provided with a weight such that it only floats on the liquid level to a smaller extent, but is immersed to a greater extent in the liquid. This may make opening easier.
  • the closure part is an immersion ball 49.
  • the cage 25 projects into the interior of the metering accumulator 1 and is of such a width that the immersion ball 49, as illustrated in FIG can roll, completely opening the opening 5.
  • 11 has three standing surfaces 50.
  • the immersion ball is located in the opening 5, closing it.
  • the metering reservoir 1 can be placed either on the right or the left standing surface 50.
  • the diving ball 49 is then in one of the positions shown in broken lines.
  • the opening 5 is free and washing treatment liquid can be poured into the interior of the metering reservoir 1.
  • the upper opening of the cage 25 can be closed, for example, by webs 51. The space between the webs 51 is selected so that the immersion ball 49 cannot escape from the cage 25.
  • the ball 49 is designed as a floating ball.
  • the floating ball floats at about half the immersion depth.
  • the ball 49 floats and automatically opens the opening 5.
  • the ball 49 seals the opening 5 again.
  • the cage 25 is also of such a size in this embodiment that the ball 49 has sufficient space during filling.
  • the outlet opening is covered by webs 51.
  • a visor-like closure 53 is hinged approximately centrally to the dosing storage container 18 by means of an axis 52. Specifically, this closure 53 has a closure plate 54 which is seated on the opening 5 in the position represented by solid lines. The closure 53 can be moved laterally into an open position, as shown in dashed lines. Beads 55 are formed to limit the displaceability of the closure 53. In addition, 5 locking beads 56 are formed in the area of the opening, which ensure a secure mounting in the closed position.
  • the handling extension 57 of the closure 53 is provided with a height such that, at the start of the tumbling movement in the washing machine, the - damp - laundry can exert a sufficient tilting moment on the handling extension 57 to move the closure 53 from its closed position into the open position.
  • a cage 25 protruding into the interior of the dosing reservoir 1 is also formed, with slot openings 26.
  • a floating ball 49 which closes the opening 5.
  • the cage 25 can be screwed on by means of a screw thread 58.
  • the dosing reservoir 1 according to FIG. 17 is filled when the closure is unscrewed. Then the closure is screwed on again.
  • the floating floating ball 49 seals at the opening 5 even at a lower fill level. A well-dosed emptying is possible in any direction if the position changes.
  • the metering accumulator 1 according to FIG. 18 in turn has a closure plate 54 which sits sealingly on a collar 59 of the metering accumulator wall 18.
  • the metering storage wall 18 forms a fold 7. It is important that the closure plate 54 is anchored, for example welded, to the bottom 61 of the metering reservoir 1 by means of a cylindrical filling cylinder 60. Furthermore, the closure plate 54 can be closed by means of a cover 62. To fill the dosing reservoir 1 according to FIG. 18, the cover 62 is opened and laundry treatment liquid is introduced into the filling cylinder 60. The laundry treatment liquid enters the interior of the metering reservoir 1 through the openings 63. The cover 62 is then closed.
  • the laundry After being put into a washing machine and at the beginning of the laundry treatment cycle, the laundry can exert pressure on the protruding areas 64 during the tumbling movements of the dosing reservoir 1, whereby a gap results between the closure plate 54 and the collar 59, as a result of which laundry treatment liquid can escape.
  • a pendulum rod 65 is anchored in the floor 61, which carries the locking plate 54.
  • the handling area 66 which projects above the locking plate 54, can be divided at 67 (FIG. 20).
  • the handling area 66 of the metering reservoir 1 according to FIG. 19 can be opened for filling by opening.
  • the pendulum rod 65 can be screwed into a corresponding counter thread of the locking plate 54 by means of a thread 68.
  • the dosing reservoir 1 is inserted into a washing machine. Due to the wobbling movement and the resulting laundry pressure on the handling area 66, the closure plate 54 is deflected, as indicated by the broken line. Then laundry treatment liquid kit may leak. When the laundry pressure decreases, the pendulum rod 65 and thus the Locking plate 54 automatically returns to a locking position.
  • the closure member 69 is designed as a plug. It has a relatively short plug region 70 which can be driven into the opening 5.
  • the handling area 66 is designed with a height such that a sufficiently high tilting moment for opening the closure 69 is set in a laundry cycle by the moist laundry etc.
  • the handling area 66 is essentially spherical.
  • the closure 69 can be connected to the metering reservoir 1 via a thin band or the like, so that it is not lost in the laundry in the open state. But it can also be completely separated from it.
  • the 22 is constructed with two shells, namely with an inner container 71 and an outer container 72.
  • the inner container 71 has an upper opening 5, the outer container 72 has lower outlet openings 73.
  • the outer container 72 is closed by means of a lid 76.
  • the cover 76 can be snapped into place in the upper part of the outer container 72. As shown, it can also be screwed onto the lower part of the outer container by means of a screw thread 77.
  • the inner container 71 is movably received in the outer container 72. 22, the lid 76 is opened and laundry treatment liquid is introduced into the inner container 71.
  • the lid 76 is then closed again and the metering reservoir 1 is inserted into a washing machine or the like. After the tumbling movement in the washing machine begins, the laundry treatment liquid emerges from the inner container 71 via its upper edge 78, which acts as an overflow, and flows in down to the outlet openings 73. Because of the movable receptacle of the inner container 71 in the outer container 72 and the wobbling movements in the washing machine, the inner container 71 always lifts off from the sealing ring 74, so that the laundry treatment liquid can finally exit through the outlet opening 73 into the washing machine .
  • the cover 76 can have a crossbar 79 for better handling of the cover.
  • the cover 76 can also have centering webs 85 for centering the opening 5 of the inner container 71.
  • the closure part 4 has a closure collar 82 which cooperates in a sealing manner with the end cover 80 of the cage 25 when the closure part 4 is pulled up into the closed position.
  • the closure part 4 is designed to encompass a total of an edge region 83 of the metering reservoir 1 and has an outer gripping bead 84. To fill the metering reservoir 1, the closure part 4 is in the depressed position shown in FIG. 23.
  • the metering reservoir 1 shown in cross section in FIG. 24 is essentially spherical in shape, with a clip-lockable closure cap 93 formed in the upper pole region. Above the equator 94, outlet openings 5 are formed which are closed by a closure part 91 in the closed state.
  • the closure part 91 consists of a flexible plastic ring which is preloaded on the sealing area 90, i.e. the outer wall area of the metering reservoir 1 surrounding the outlet openings 5.
  • the closure part 1 is formed in its upper region with a smaller diameter d than in its lower region. However, the diameter d of the closure part 91 in its lower region is smaller than the diameter of the metering reservoir 1 in the region of the equator 94.
  • the closure part 91 can also be formed from a special thermally expandable material.
  • the temperature increase of the washing water during the course of the laundry treatment cycle can result in an enlargement of the closure part 91 and thus practically an automatic lifting of the closure part 91 from the outlet openings 5. It is also possible for the closure part 91 to only fit loosely over the outlet openings 5, that the laundry treatment liquid can easily escape in the heated state.
  • Barriers 92 are formed above the outlet openings 5, onto which the closure part 91 runs upwards during an opening movement, as shown in FIG. 26. These locks 92 serve on the one hand as stop elements for an opening movement of the closure part 91, and on the other hand as a means to tie the closure part 91 to the metering reservoir 1. Alternatively, which is not shown in detail in the drawings, the lock 92 can also be designed as a circumferential rib.
  • the Barriers 92 as shown in FIGS. 24-26, are shaped in detail as ribs running on a meridian on the outer surface of the metering reservoir 1.
  • a handling extension 95 is formed on the closure cover 93 for easier handling.
  • the closure cap 93 of the metering reservoir 1 is opened as shown in FIGS. 24-26 and laundry treatment liquid is poured into the interior of the metering reservoir 1 from above.
  • the closure part 91 is shifted by hand from the position shown in FIG. 26, which it assumes after a washing process, to the position shown in FIG. 24 or FIG. 25. Due to the elasticity and the shape of the closure part 91, this remains in the closure position shown in FIG. 25.
  • the closure cap 91 is closed in a snap-in manner and the metering reservoir 1 is inserted into a washing machine or the like.
  • the laundry pressure exerts such a force on the closure part 91 that it is moved upwards into an open position according to FIG. 26.
  • the closure part 91 expands due to the heat of the wash water and can thus be easily moved into the open position according to FIG. 26.
