Definitions

  • the invention relates to an automatically controlled laundry treatment machine having a detergent flushing device which is arranged in the machine interior and comprises a receiving chamber for a storage container for liquid or gel-form treatment agents, said receiving chamber being accessible from the outside, and a device for automatic dosing of every stored treatment agent.
  • a transportable container which can be inserted as a storage container into the dosing device of a washing machine.
  • the storage container is automatically coupled to a fluid line which contains a conveying device for portion-wise drawing of the treatment agent out of the storage container.
  • said container can be configured as in DE 34 03 622 A1, that is, such that for dosing, an active or passive mechanical device is provided which opens a valve for a particular time or to a particular width, such that the portion flows out into a dosing chamber.
  • active devices for conveying treatment agent portions for example, pumps, solenoid valves or shut-off sliders.
  • the receiving chamber is configured for receiving a transportable container for a supply containing a plurality of doses of liquid or gel-form treatment agent and the dosing device operates purely in a fluid-mechanical manner and is equipped with a hydraulic siphon system.
  • the container has a capacity that is large enough so as to require changing only seldom and the dosing device operates without any external energy input and entirely without movable parts which, during operation would otherwise gradually become scaled and blocked from the more or less lime-laden water. Reliable dosing would then no longer be possible.
  • the hydraulic siphon system comprises three vertical channels which are connected to one another in series by a lower bend and an upper bend, the last channel in the series comprising an outlet opening to a flushing channel of the laundry treatment machine, and the first channel in the series being upwardly open and corresponding with a switchable water inlet of the laundry treatment machine and having an input opening directly above the lower bend for the treatment agent from the storage container.
  • the receiving chamber and the dosing device can be components of the laundry treatment machine and the storage container can be coupled to the dosing device.
  • the storage container can then be restricted to the minimum of the components thereof required for transportation.
  • a coupling device for connecting the interior space of the container to an input opening of the dosing device is arranged within the form of the receiving chamber.
  • This coupling device must be configured to be particularly simple and functionally certain in order for a reliable sealing connection to be made between the storage container and the dosing device in every case.
  • the receiving chamber is a component of the laundry treatment machine and the dosing device is a component of the container.
  • the configuration of the coupling to the washing agent dispensing system is very much simpler.
  • this proposal requires the integration of the dosing unit into the storage container. This can also be realized on a technical scale in mass production and ensures enduring functional reliability. Ease of use is advantageous for the operating person.
  • the storage container must be sealed while able to be transported.
  • the container has an outlet opening which is blocked for transport of the container and, for use of the container in the laundry treatment machine, can be unblocked.
  • FIG. 1 is a schematic representation of a washing machine in a transparent view from the front
  • FIG. 2 is a storage container which is connected via a coupling to a dosing device arranged in the washing machine,
  • FIG. 3 is another storage container with integrated dosing device.
  • the washing machine shown in FIG. 1 has a cabinet-shaped housing 1 into which a washing solution container is installed, which can be fed from above with a washing agent-water mixture via a flushing channel 3 .
  • This mixture is made in the dosing devices 4 in that a dose of liquid treatment agent is taken from the associated storage container 5 and is mixed with fresh water from the fresh water inlet 6 .
  • the fresh water inlets 6 are controlled from a mains power connection 7 via a distribution device 9 switchable by a control device 8 .
  • the containers 5 and dosing devices 4 shown here are only schematically indicated and are not intended to disclose any features that would indicate the dimensions, position or function thereof.
  • the storage containers 5 are accommodated in receiving chambers 10 which are accessible from outside the washing machine.
  • FIG. 2 shows schematically a transportable container 11 , which has a form which is suitable as a storage container 5 and is insertable into a receiving chamber 10 which is accessible from outside the washing machine.
  • the dot-dashed frames 12 , 13 and 14 indicate the limits within which the respective assemblies of transportable container 11 , coupling 15 and dosing device 4 are arranged in the washing machine.
  • the transportable container 11 comprises nothing more than the sleeve 16 thereof and, as the only opening, a closing device in front of the outlet opening 29 (for the duration of the transport and storage outside the washing machine and is therefore no longer shown here) and a filling 17 of treatment agent.
  • the coupling 15 is delimited by the two vertical dashed lines.
  • the dosing device 18 comprises a series of adjacent vertically arranged channels 19 to 22 of which the channel 19 is downwardly open and opens into the flushing channel 3 .
  • the channel 19 is connected via an upper bend 23 to the adjacent channel 20 , which in turn is connected below, via a lower bend 24 to the infeed channel 21 arranged therebefore in the outflow direction 25 .
  • the infeed channel 21 serves to feed in fresh water which can be fed according to the arrow 26 into the upper funnel 27 in controlled manner.
  • the air inlet channel 22 serves to feed in air 28 , the function of which will be described below.
  • the outlet opening 29 of said container is closed at the height of the right-hand dashed line of the coupling 15 by a cover or membrane (see, for example, FIG. 4 ).
  • said cover or membrane is firstly removed and the outlet opening 29 is connected to the coupling 15 .
  • said connection is now made or has already been made.
  • the treatment agent runs into all the channels of the lower region of the dosing device 18 until the upper edge of the outlet opening 29 is reached.
  • the treatment agent passes into the lower regions of the air inlet channel 22 , the infeed channel 21 and the channel 20 and into the lower bend 24 . Due to the narrower opening 30 which acts as a throttle, the inflow of treatment agent into the lower bend 24 and the adjacent channels 20 and 21 is delayed.
  • the internal and external pressures are equal.
  • the quantity of treatment agent now situated in the lower region of the dosing device 18 corresponds to a standard quantity.
  • the standard quantity is adjustable within particular limits which also take account of the viscosity of the treatment agent.
  • the lower region of the dosing device 18 in the direction of flow of the treatment agent can also be enlarged behind the throttling opening to the required amount.
  • This standard quantity of treatment agent is replaced by air flowing in through the air inlet channel 22 and the outlet opening 29 in the storage container 11 until the dosed standard quantity reaches the upper edge of the outlet opening 29 . The air rises as bubbles through the treatment agent in the storage container 11 .
  • the liquid level within the dosing device rises to the level of the upper bend 23 and flows as a water-treatment agent mixture in the direction of the arrow 25 through the channel 19 and the flushing channel 3 into the washing solution container 2 .
  • no further treatment agent can flow out of the transportable container 11 (which is now a storage container 5 ). Only when the inflow of fresh water into the infeed channel 21 predominates does the level fall below the upper edge of the outlet opening 29 .
  • treatment agent runs in again from the transportable container 11 , as during the first time. Treatment agent also flows to a small extent out of the transportable container 11 into the lower region of the dosing device 18 . However, this quantity is negligibly small due to the throttling opening 30 .
  • the quantity can be multiplied by one or more influxes of fresh water until the total quantity is sufficient.
  • a small quantity of fresh water is sufficient each time for feeding in the dose, for example, 300 ml in each case.
  • the level of the mixture in the lower region of the dosing device 18 falls. From the time point at which said level has fallen below the upper edge of the opening 30 between the infeed channel 21 and the air inlet channel 22 , air 28 flows through the air inlet channel 22 into the lower region of the dosing device 18 and interrupts the flow of mixture.
  • the small residue of the mixture which has not flowed out runs from the upper bend 23 back again and now treatment agent flows out of the transportable container 11 again until the dosing level is reached once again. Now a further influx of fresh water can feed in another dose.
  • the functions of the transportable container and the dosing device 18 shown in FIG. 3 are identical to those in FIG. 2 . Said functions will therefore not be described here again.
  • the dosing device 18 with all the details thereof belong to the transportable container 31 of FIG. 3 . Therefore the coupling 15 is unnecessary because the dosing device 18 is a component of the transportable container 31 and for this reason, is rigidly connected to the shell 16 of the transportable container. Therefore, in FIG. 3 , it is only the flushing channel 3 and the infeed and air inlet functions indicated by the arrows 26 and 28 which belong to the washing machine, as indicated by the frame 14 .
  • the opening of the funnel 27 corresponds to the fresh water inlet 26
  • the opening of the air inlet channel 22 corresponds to the respective ambient air inlet and the opening of the channel 19 corresponds to the flushing channel 3 .
  • Said closing device essentially comprises a cover which is guided and removable vertically and becomes immersed with the lower edge thereof into a flat groove of the transportable container sleeve 16 .
  • the cover has a hinge which is connected to a traction means. With said traction means, an operator can pull the cover away upwardly and thereby free the inlet opening 29 in order to allow the treatment agent to flow into the lower region of the dosing device 18 .
  • a membrane which is removed by comparable means can be attached and fastened so as to seal the outlet opening 29 with a peripheral welded or glued seam until the removal of said membrane.
