Description

Cooling device for cooling a fluid medium and method for cooling fluid medium

The invention relates to a cooling device for cooling a fluid medium, in particular a cooked, serving as a food or for its preparation liquid. In addition, the invention relates to a method for cooling fluid medium, in particular a cooked, serving as a food or for its preparation of liquid, one in one

Set temperature range lying end temperature with such a cooling device.

In particular, in the preparation of baby food, for example, the dissolution of milk powder, it is often necessary, a hot, especially cooked,

Liquid, here water, from a starting temperature, for example 100 ° C, quickly to a lower final temperature, for example 40 ° C to cool. For this purpose, cooling devices have been proposed in the prior art, in which, for example, cooked hot water can be filled to this by a cooling process to the desired final temperature in a

Cooling set temperature range. EP 2 002 187 B1 also relates to a hot water cooling device

Method for cooling hot water to a serving temperature. There it is proposed to achieve a possible defined cooling process by a separate from the actual cooling device filling vessel is used with a defined filling volume. On the filling vessel, the cooling unit is screwed, which ultimately guided by a guided by a coolant

Cooling line is formed, whereupon the thus formed total cooling device is tilted and the cooling process is initiated. The hot liquid present in the filling vessel then enters the inlet of the cooling unit, passes through the cooling line, the hot liquid being defined

Amount of heat is withdrawn, and then from the outlet of the cooling unit. In this case, it is also exploited that the possibility of forming an objective unit between the filling vessel and the cooling unit in the process of tipping over the present in the filling vessel air through the hot liquid rises to the bottom of the hopper, thereby warming and expanding to create a pressure which increases the flow rate of the

cooling liquid supported by the cooling line. The pressure equalization is ensured by a ventilation opening.

Such a known cooling device has a plurality of disadvantages. On the one hand, the cleaning possibilities of the cooling line of the known cooling device are limited due to the small diameter which is required for adequate cooling of the water. A user can not see the inside of the cooling line, with the result that possible blockages, for example due to limescale of a kettle, are difficult or impossible to fix. Other particles may also lead to blockage of the effluent or within the cooling line. In known, on the market available cooling devices with cooling line, the inlet opening

for example, a diameter of 3.5 mm, the outlet opening a

Have diameter of about 2 mm, which greatly limits cleaning options.

In order to achieve a sufficient cooling effect, it is also possible and necessary for a cooling device using a cooling line with throughflow cooling

To use aluminum as a material. Aluminum has the disadvantage that it is not suitable for the dishwasher cleaning, while cooling pipes made of other materials, such as stainless steel are not sufficient to allow sufficient heat exchange within the same space. In addition, aluminum is not an ideal material for the food industry.

Another problem with refrigerators using a separate hopper is that the hopper becomes very hot when filling the hot liquid, especially after it has in fact to be completely filled to avoid a so-called "steam blast."

Injuries occur when screwing in the cooling unit

Filling must be held or hot liquid is spilled from it. Also, it may be in a screw to jamming and a not complete seal come. The use of additional components, such as a protective cover, or thicker wall thicknesses, would lead to relatively high production costs. The cooling pipe, which is usually realized as a spiral in the known state of the art, is extremely complex, in particular in the case of aluminum, since several production steps are required which cause high costs in the production of the cooling pipe. Also, an optical control of the interior of the cooling line is not economically feasible in the production. Similar problems occur in the anodization of the cooling line inside.

The invention is therefore based on the object, with respect to the preparation, the ease of handling and cleaning improved cooling device and an associated cooling method using this cooling device to specify.

To solve this problem, a cooling device of the type mentioned above according to the invention:

a coolant vessel for a coolant for cooling the medium, which is delimited by an outer cooling surface,

- A concentric surrounding the coolant vessel, by an inner

Boundary surface together with the cooling surface of the coolant vessel a filling space for the liquid-defining filling vessel, which has a filling opening for the medium to one side, and

- A closing the filling opening, an outlet opening for cooled

Medium terminating element, so that after filling the

Medium through the filling opening into the filling space, closing the filling opening by the closing element and turning the cooling device by 180 °, the cooled medium through the outlet opening of the

Filling space emerges.

The invention provides a simple to produce, compact and easy to handle cooling device available that can still provide the desired cooling effect, for example, when cooked water for the preparation of baby food is to be cooled to a lying in a desired temperature range end temperature, for example, serving temperature. For this purpose, a cooling unit is used which is formed by a filling vessel and a filling vessel located inside the filling vessel, a filling space defining coolant vessel, so that the hot liquid to be cooled is brought directly into contact with the cooling surface of the cooling vessel and a cooling effect occurs, the already Risk of injury minimized. After the cooling process already begins when filling a relatively large area, namely the cooling surface of the coolant vessel, the

Coolant vessel from particular dishwasher-suitable and / or less critical in the field of food materials are produced.

In order to use the cooling device, the method according to the invention for cooling fluid medium to an end temperature lying in a desired temperature range with the cooling device according to the invention provides the following steps:

Filling of a quantity of coolant, in particular water, which is selected as a function of the desired temperature range, into the coolant vessel,

Cooling the coolant to a defined coolant temperature,

in particular refrigerator temperature,

- Fill a defined amount of the to be cooled, on one

Start temperature located medium in the hopper, whereby the

Medium comes into direct contact with the cooling surface and the cooling process begins,

Immediately after filling the filling vessel with the closing element and turning the cooling device such that the outlet opening is arranged below,

- Collecting the discharged from the outlet opening cooled medium of the final temperature.

Of course, all versions of the method can be transferred to the cooling device and vice versa.

In particular, the cooling device thus also offers the possibility of a

Adjustment by adjusting the amount of coolant in the coolant vessel accordingly is selected, wherein water is preferably used as a coolant. It can therefore, in order to prepare the cooling device, a certain volume of coolant, in particular water, are introduced into the later acting as a heat exchanger cooling vessel, depending on the desired cooling effect. If the filled coolant, in particular water, is still too warm, a cooling storage is now to be carried out, for example in the refrigerator, in order to achieve the desired defined coolant temperature, in particular the refrigerator temperature.

After the cooling device has possibly been removed again from the refrigerator and the closing element, which is expediently arranged for storage the inlet opening on the cooling device has been removed, located at the starting temperature to be cooled liquid, such as boiling water, in a defined amount in the filling space are filled. At this time, the cooling device preferably stands on a surface facing away from the inlet opening, so that it can be said that the bottom of the cooling device is located opposite the filling opening. After filling the medium, in particular the boiling water, directly the end element, which is preferably configured as a cover and / or screwed attached, mounted so that the filling is closed watertight except for the outlet. Now, the cooling device is turned and, for example, on a to be filled

Receptacle, such as a baby bottle, put on, flows to be cooled medium, in particular the water to be cooled through the

Outlet opening in the closing element at the desired in

Target temperature range lying target temperature.

After, in the example of the boiling water, this comes directly into contact with the cooling surface of the cooling vessel, an immediate cooling occurs, so that suddenly a significantly lower temperature than the starting temperature and therefore the risk of injury is reduced. In addition, the

Requirements for the cooling surface compared to a guided through the coolant cooling line significantly reduced, so that material savings can be made, the choice of materials can be adjusted and / or the required Space can be optimized. Ultimately, the distance between the

In principle, the boundary surface and the cooling surface, that is to say the expansion of the filling space, are rather small in the present invention, so that during filling a thin layer of the medium to be cooled is placed around the cooling surface, which improves the cooling effect and the use of materials with relatively poor Enables heat exchanger properties, however, which can be selected more suitable with regard to the use of food and / or the Spülmaschinentauglichkeit. It is expedient, which will be discussed in more detail below, if the shape of the individual components, the outflow is suitably delayed to reach the target temperature in the set temperature range; The almost complete filling with medium to be cooled also avoids a kind of "steam pulse" of the boiled water when turning the cooling device In order to allow the necessary pressure compensation, it can be provided that the closing element and / or the filling vessel at least one

Have air inlet opening for the subsequent flow of air at the outlet of medium to be cooled from the outlet opening and / or form upon closure of the filling opening by the closing element. Such

Air inlet opening can be realized, for example, by at least one notch, so that when the end element is placed on the filling vessel, air can flow into the filling space when the medium exits through the outlet opening. As has already been mentioned, expediently a screwing on of the closing element can be realized so that, for example, corresponding notches can be provided in the thread.

Of course, it is also conceivable to realize the air inlet opening through a borehole and / or a slot.

Depending on the geometry, it may be useful to match the outlet opening and the air inlet opening in height difference and size to each other in order to ensure optimum flow of the medium from the filling space. As already mentioned, the air inlet opening can be provided both on the closing element and on the filling vessel. There are also variations of Present invention conceivable in which the (for example, via a valve and / or a closing element closable) outlet opening is located on the filling vessel and is released to discharge the water. It should be noted at this point that the vote in height difference and size, as regards the air inlet opening and the outlet opening, and the speed of the outflow of the medium can influence, so as to be able to define the cooling process accurately. In addition, the air inlet opening can of course be provided with a valve in order to avoid an unwanted escape of medium to be cooled at the appropriate size and position.

As already mentioned, the special cooling concept of the

Cooling device according to the invention the use of easy-to-use, dishwasher-safe and / or as food-appropriate materials. An advantageous embodiment of the present invention provides in this

Context that the coolant vessel is made of stainless steel. Stainless steel is suitable for use with food and for dishwashers and also allows easy production of the coolant vessel, which can be made for example by deep drawing with very thin wall thicknesses. A particularly preferred embodiment of the present invention is given when the coolant vessel tapers conically towards the filling opening. For example, the vessel having a circular cross-section may have a radius which reduces toward the filling opening, wherein it is at least partially flat, in particular towards the filling opening. In this way, for example, when as a medium to be cooled

boiling water is added, the occurrence of splashing is reduced and even completely prevented. By such a shaping, the duration of the contact of the medium to be cooled with the cooling surface is also specifically extended.

These effects are also favored by the relatively large radii of the cooling vessel. For example, it may be provided that a radius of the

Cooling surface more than 75% of the radius of the boundary surface, in particular more than 80% of the radius of the boundary surface. In this way, created by the coolant vessel, in particular together with in the

Einfüllbereich tapered shape, through the cooling vessel located in the hopper heat sink, in which the medium to be cooled in a relatively thin layer in the filling space around the cooling surface sets. When filling syringes and the like is largely or even completely avoided.

It should be noted that the invention is particularly advantageous as easy to disassemble and thus improved cleaned provided. In particular, therefore, the coolant vessel, the filling vessel and the closing element and, if appropriate, further provided

Realize components separable from each other, with appropriate

Connecting means can be provided, in particular thread for screwing, snap means and the like. In such a separable embodiment, a complete cleaning of the cooling device is made possible, with particular advantage, all materials are chosen dishwasher safe. It should be noted in general that expediently the

End element and the filling vessel can be made of a plastic.

In an expedient development, the cooling device may further comprise a coolant vessel lid for closing a coolant opening of the

Have coolant vessel. About the closable coolant opening it is possible in a particularly simple manner, the already mentioned, depending on the desired temperature range selected amount of coolant in the

Incorporate coolant vessel. The coolant vessel cover can over

corresponding thread can be screwed or screwed.

Conveniently, a particular molded or not attached to other components of the cooling device sealing element to prevent the escape of coolant from the coolant opening may be provided at the coolant port closing coolant vessel lid. Such

Sealing element can be provided for example as a sealing ring, is conceivable However, it also to use molded seals and / or snap seals.

In a particularly advantageous embodiment in this context can

be provided that the coolant vessel lid the coolant vessel and the filling vessel of the filling opening opposite and seals the sealing element the filling space and the interior of the coolant vessel against each other and to the outside. In this way, ultimately, three components of the cooling device can be sealed with a single sealing element, namely the

Filling vessel, the coolant vessel and the coolant vessel cover. It is particularly preferred in this context if the coolant vessel lid is realized as a bottom lid. The sealing element is closed by closing the

Coolant vessel lid, for example by screwing, pressed so that the sealing effect between the filling and the interior of the

Coolant vessel and in each case enters the outside. A conceivable one

Embodiment provides that the cross section of the coolant vessel widens toward the bottom, so that the outer boundary of the coolant vessel essentially touches the boundary surface of the filling vessel. Will that be

Sealing element now, for example in the form of a sealing ring over this

Approach area established, an excellent sealing effect can be achieved outwards and to each other.

As has already been stated, the cooling device can advantageously be dismantled, that is to say be implemented with separable components. For example, it may be provided that the coolant vessel, the filling vessel, the

End element, the coolant vessel cover and possibly the

Sealing element are separable components of the cooling device. This allows complete cleaning, especially if all these components are dishwasher-safe. The coolant vessel, the

Filling vessel, the closing element, which is realized in particular as a cover made of plastic, and the coolant vessel cover can thus be cleaned separately, with all external surfaces are easily accessible, in contrast to a thin cooling line. Is the sealing element, if present, not molded or otherwise firmly connected to another component

Of course, this, for example in the form of a sealing ring, separately cleaned. In a preferred embodiment of the invention, the filling vessel and / or the coolant vessel at the cooling surface at least one

Have quantity marking for filling the filling space. It may be useful, moreover, if the filling vessel is at least partially transparent, especially when quantity marks on

Coolant vessel are provided. It is therefore a simple way a level indicator by markings on the coolant vessel and / or on

Filling vessel conceivable.

In a particularly advantageous embodiment of the invention, the

Coolant vessel and / or the filling vessel and / or the closing element have a projecting into the filling space Mediumleitstruktur for guiding the medium along the cooling surface. By appropriate shaping to the

Components is thus passed the outflowing medium, so that a defined contact time / contact surface is realized on the cooling surface. In particular, such a medium-guiding structure extends completely through the filling space, so that complete guide sections are provided for the medium to be cooled.

It is particularly advantageous if the medium guiding structure has at least one rib and / or at least one labyrinth leading in particular to the outlet opening and / or a spiral section leading in particular to the outlet opening. In this case, the medium guiding structure is at least partially provided on the part of the terminating element, wherein a spiral section leading to the outlet opening is particularly preferred. Is the Mediumleitstruktur completely provided by the end element, it has less disturbing when filling the medium.

Preferably, in a removable from the filling vessel

Coolant vessel, the filling vessel at least one inwardly facing Have spacers for guiding the coolant vessel during insertion. These spacers then protrude, preferably as a web, from the boundary surface and define a position for the coolant vessel, which can be easily inserted into the filling vessel. This simplifies the reassembly clearly in a separable variant of the cooling device.

For reasons of simple production, it is preferred according to the invention to produce the most uniform possible course of the boundary surface and the cooling surface, in particular a linear and / or only curved in one direction course. In particular, it can be provided that the distance between the cooling surface and the boundary surface in a vertical section is substantially constant, for example over at least 70%, in particular at least 80% of the height of the filling space, or from one

Removing filling opening increases, so that more medium to be cooled is absorbed in the bottom area, thus a longer cooling effect is ensured for larger proportions of the medium to be cooled. For example, the distance between the cooling surface and the boundary surface in the horizontal direction over a vertical section of the cooling device may increase in particular slowly such that the ratio of the radii of the cooling surface of the boundary surface from a starting value, in particular in the range from 0.80 to 0.90, to a final value, especially in the range of 0.65 to 0.75.

However, it can also be provided that the filling space in one of

Filling end facing away from the end portion has a reservoir portion in which the boundary surface and the cooling surface have a greater distance than in a filling opening facing the inlet and outflow section. It is particularly expedient if the reservoir section is defined by an indentation of the coolant vessel and / or the filling vessel. In this case, therefore, a reservoir for the medium to be cooled is created specifically close to the ground, in which then the majority of the medium to be cooled is present during filling. If the cooling device is now tilted in order to start the outflow process, the medium to be cooled flows through the extremely narrow upper region of the Filling space in which the boundary surface and the cooling surface are significantly closer, which supports the cooling effect.

Conveniently, the cooling device may further comprise a protective cap for the outlet opening of the closing element. In this way, a protection against dirt and a dripping of residual medium is given. For example, such a protective cap made of a soft plastic and be pressed into a structure surrounding the outlet opening profile structure or pushed onto it.

In general, it is also expedient to provide a profiling of the closing element, in particular end cap, in the region of the outlet opening for the cooled medium such that when the cooling device on a

Collecting vessel is placed, air from the collecting vessel, such as a baby bottle, can escape, while the cooled medium, in particular water, flows into the collecting vessel. For example, recesses and / or indentations in the profile, alternatively and / or in addition but also webs, can be provided, which act to ensure that no completely airtight

Placement of the end element with the outlet opening on the collecting vessel occurs.

It is also particularly expedient if, in particular in the case of a separable cooling device with separable components which can be cleaned separately, the so-called poka-yoke principle is used for the components, so that they can only be mounted in a specific arrangement.

Overall, and generally discussed, the present invention thus provides a cooling device that is easy to manufacture, handle and clean and yet a well-defined cooling effect with a target temperature in one

Set temperature range allows. In contrast to variants with a pure flow-through cooling system, it is not necessary to have a cooling line which is guided through the coolant and which is difficult to clean. also an additional filling vessel with defined

Filling volume is not needed, after all, the cooling unit with the Filling vessel is combined. Hot medium, in particular hot water, can be cooled to defined target temperatures in defined periods of time, wherein the cooling effect can be adjusted by means of the cooling volume of the coolant vessel. With separable components, thus given by appropriate connecting means targeted disassembly, significantly improved cleaning options compared to the prior art are given. In addition, the construction is considerably simplified, whereby high savings in manufacturing costs are made possible. In particular, no welding of components is necessary, no additional

Measuring cup and overall the number of components is reduced. On the

Producing complicated cooling lines can be dispensed with. Also can be dispensed aluminum as a material and instead, for example

Stainless steel can be used as material for the coolant vessel. Possible

Injuries due to scalding are caused by the inventive

Cooling device significantly reduced, especially after the cooling process begins with the filling.

It should be noted at this point that the cooling device can also be used elsewhere, for example for cooling drinks without

End element and the like.

Further advantages and details of the present invention will become apparent from the embodiments described below and with reference to the drawing. Showing:

8 shows a sketch of a filling space with reservoir section.

Figures 1 to 7 show a first embodiment of a

Cooling device 1 according to the invention and ideally are to be considered together. As can be seen from Figures 1 and 2, showing the cooling device 1 in a (fully assembled to a protective cap) state, the cooling device 1 comprises a filling vessel 2 made of plastic, which concentrically a coolant vessel 3 (see Fig. 2) Stainless steel surrounds. The

Coolant vessel 3 expands its radius visible in the bottom, lower portion of the cooling device 1, so that its edge ultimately to the inner

Surface of the filling vessel 2 is applied. This allows one here as

Ring seal, in particular made of rubber, TPE or silicone, trained

Use sealing element 4, which is pressed by a coolant vessel lid 5, which is screwed here, sealingly to the coolant vessel 3 and the filling vessel 2, so that it unfolds its sealing effect with respect to these three components.

Between the cooling surface 6 as the outer surface of the coolant vessel 3 and the boundary surface 7 as the inner surface of the filling vessel 2, this forms a filling chamber 8. The filling opening of the filling chamber 8 is in the

Representations of Fig. 1 and Fig. 2 by a screw-on

Cover cover covered as a final element 9, in which a

Outlet opening 10 and an air inlet opening 1 1 are provided.

The outlet opening 10 with the surrounding profile section 21 of the

End element 9 can optionally be covered by a protective cap 12 in order to ensure protection against residual fluid and dirt. If the coolant vessel cover 5 (bottom cover) is unscrewed, coolant, for example water, can be introduced into the coolant vessel 3. The amount of coolant depends on the desired setpoint temperature range for the medium to be cooled, for example boiled water. If boiled water (at 100 ° C) to be cooled to a temperature of 40 ° C, the interior of the coolant vessel 3 is substantially completely filled and filled therein coolant, especially water, on

Refrigerated tank temperature brought after the coolant vessel cover 5 (with inserted sealing element 4) was replaced. It should be noted that the sealing element 4 can of course also be injection-molded, and, while the coolant vessel 3 is made of deep-drawn stainless steel, the filling vessel 2, the closing element 9 and the coolant vessel cover 5 are made of plastic. The sealing member 4, as mentioned, may be made of rubber or other sealing material (TPE, silicone).

Already at this point it should be noted that by the here as

Screw connection realized connecting means all components 2, 3, optionally 4, 5 and 9 of the cooling device 1 are easily separable from each other, so that the cooling device 1 can be dismantled and their

Components, all of which are dishwasher-safe, can be cleaned separately.

Apparently, cf. Also Fig. 3, the radius of the reduced

Coolant vessel 3 in an end region upwards, ie towards the filling opening, so that consequently a conical taper is given. Nevertheless, over the substantial portion of the height of the cooling device 1 is given a relatively large radius, for example, the ratio between the radius of the

Cooling surface 6 and the radius of the boundary surface 7 greater than 0.75 can be selected, resulting in a narrow and layered around the cooling surface 6 extending filling chamber 8 clearly defined volume, for example, a volume of 210 ml results. Presence also tapers the filling vessel. 2 light, so that the radius ratio can fall from top to bottom, for example, from 0.85 to 0.75.

Due to the conically tapered shape of the cooling vessel 3, a cooling vessel located in the filling vessel 2 is ultimately realized, which largely prevents splashing of the medium to be cooled during filling, wherein in addition to the filling of the medium to be cooled, in particular of boiling water, a direct contact with the Cooling surface 6 occurs and already a significant cooling of the medium to be cooled takes place, which reduces the risk of injury from scalding.

As can be seen in the perspective view of the filling vessel 2 of FIG. 4, the concentric position of the coolant vessel 3 during assembly of the cooling device 1 is assured by spacers 13 which protrude as webs from the boundary surface 7. On the outer surface of the filling vessel 2 are also the threads 14, 15 for the closing element 9 respectively

Recognize coolant vessel cover 5.

The coolant vessel lid 5 is shown in FIG. 5 in a perspective view. To recognize is the thread 15 corresponding to the thread 16. Centrally in the coolant container lid 5 produced as a molding two recesses 17 are provided which have a handle for easy up and screwing the

Coolant vessel cover 5 form. FIGS. 6 and 7 show perspective views of the end element 9 realized as a cover plate, with the thread 18 corresponding to the thread 14 being initially visible on the inside. In the screwed-on state of the cooling surface 6, a spiral section 20, which leads to the outlet opening 10, is provided as the medium-guiding structure 19. Evident is also outside of the spiral section 20, the air inlet opening realized via a slot 1 1. On the outside of the closing element 9, the outlet opening 10 surrounding a profile structure 21 can be seen, which supports the placement on a collecting vessel, in particular a baby bottle. In particular, five webs 22 can be seen, via which a clear distance and thus an air outlet opening for exiting from the collecting vessel, displaced by the cooled medium air remains present.

For use of the cooling device 1, the cooling of boiled water (starting temperature 100 ° C) to about 40 ° as an example

Target temperature range lying target temperature described. First of all, this is ideally already used in the filling vessel 2 at this time

Coolant vessel 3 is substantially completely filled with water as a coolant. Then, if it is not molded, the sealing element 4 is inserted and the coolant vessel lid 5 is screwed tight. To the water in the

Coolant vessel 3 to a defined coolant temperature, here

Refrigerator temperature to cool, then, due to the compact storage, the closing element 9 is screwed on and the cooling device 1 is placed in the refrigerator. At a later time, when the water in the coolant vessel 3 has reached the refrigerator temperature, water is boiled as the medium to be cooled. The cooling device 1 is removed from the refrigerator and the closing element 9 is unscrewed, so that the filling opening 25 (see Fig. 4) is exposed. A defined amount, in this case 210 ml, of the boiling water is introduced into the filling space 8 through the filling opening 25, wherein the filling vessel 2 can be made transparent at least in a transparency region 23, so that the filling level and quantity markings 24 on the limiting surface 7 or the cooling surface 6 become visible. The filled hot water immediately comes into contact with the cooling surface 6 and the cooling process begins, the water already significantly cooling.

Immediately after filling the water to be cooled then the

Closing element 9 firmly screwed again and the cooling device 1 is in Essentially inverted by 180 ° and placed on a receptacle, such as a baby bottle. The water to be cooled flows in the filling space 8 initially flat against the cooling surface 6, is then through the

Mediumleitstruktur 19 spirally further along the cooling surface 6 and finally exits through the outlet opening 10 into the collecting vessel, while for pressure equalization through the air inlet opening 1 1 air flows into the filling chamber 8 and thanks to the webs 22 air exits the collecting vessel.

The expansions of the filling chamber 8, the coolant temperature, the

Coolant quantity and the delay and further cooling by the

Spiral section 20 are coordinated so that the water with a target temperature in the desired temperature range, ie about 40 ° C, the

Cooling device 1 leaves, wherein for the period of filling, the

Screwing the closure element 9 and the turning of the cooling device can be assumed a clearly determined period of time.

Another fine adjustment can also by voting

Height difference and size of air inlet opening 1 1 and outlet 10 can be achieved.

Finally, FIG. 8 shows, in the form of a schematic diagram, another geometric configuration of the filling space 8, wherein a recess 26 is provided in the lower region of the filling vessel 2, so that a reservoir section 27 is formed there. By contrast, the inflow and outflow section 28 is significantly narrower than in the exemplary embodiment according to FIGS. 1 to 7.
