Description

The present invention relates to a device for enriching piped drinking water with a water-soluble Gas such as carbon dioxide or oxygen according to the preamble of the claim 1.

In known enrichment devices conducted Drinking water with carbon dioxide is passed through a mixing chamber Supply of drinking water and over a gas line fed carbon dioxide. In the mixing chamber the drinking water with the carbon dioxide and that with carbon dioxide Spiked drinking water is in a tap of a tap fed. Carbon dioxide-contaminated drinking water can then be taken from the tap become. It is known that the carbon dioxide in such devices to be kept in an exchangeable storage container.

Serves to hold the storage container a holder. This has a connector for connecting to a reservoir side Counterpart on. The connection of the connector and counterpart serves the establishment of a fluidic connection between the reservoir and Gas line.

The one with such a device Holders used are those used in the respective system reservoir Voted. Doing so the pressurized storage container securely through the holder be added to possible accidents to avoid.

The use of only one type of storage containers in connection with a holder has the disadvantage that, for example the volume of the storage container not adapted to the consumption of carbon dioxide in the device can be. This can cause that reservoir over a are arranged on a system for a long period of time or else a very common one Change of the storage container is required.

In contrast, it is an object of the invention To create device by means of which a greater flexibility in the used storage containers is achieved and in which the storage container easily and without great assembly effort can be exchanged.

The basis of the invention The object is achieved by a device according to independent claim 1.

Due to the inventive design of the Holder is enabled reservoir different external dimensions and thus also to use different volumes. Since it is at Gas bottles and gas cartridges are largely common that the cartridges with a small volume not only a smaller outside diameter but also have a smaller axial length, it will only in connection with the longitudinally displaceable arrangement of the tray with the formation of wings of different outer diameters possible, storage tanks different Size in the holder to record safely.

The system is therefore by the invention with regard to the use of different storage containers and improved in terms of easy replacement of storage containers.

According to a preferred embodiment of the Invention, the support floor is stepped and has circular and / or circular concentric wings on. The stair-like gradation makes it possible to work on one and the same Tragboden several, so at least two, to form wings, so that one and the same support floor is suitable in connection with different storage containers to be used. It is also possible that the clear width above a wing the outside diameter one on this wing supportable reservoir equivalent. As a result, not only an axial Leadership but also a lateral guide achieved in the holder in the area of the holder.

According to a further embodiment according to the invention the invention have the wings bulge on that of the bulge of the storage container is shaped accordingly in the contact area on the wings. The contour-following adaptation of the wings to the reservoir accordingly Size allows the axial support effect and the lateral guiding effect of the wings to unite in a common mold section. This can measure alternatively or additionally to adjust the clear width above the wing to the Outside diameter of the reservoir respectively.

According to a further embodiment the invention, the support base is acted upon in the axial direction towards the connecting piece. The provision of force in the axial direction serves on the one hand establishing a secure connection between the holder and the storage container, on the other hand it also allows the reservoir exchange in a simple way. It is not mandatory to use the appropriate Latches and latches ensure that the storage container is secure is held.

According to an advantageous embodiment of the invention, the holder has at least one axially parallel guide rail. The connector, which can be connected to the counterpart, is held on the guide rail. In addition, a slide is axially displaceable on the guide rail. The support base protrudes from the sled. In particular, it is a right angle provided between the carriage and the alignment of the support floor. The displaceable arrangement of a carriage on a guide rail enables the support base to be held longitudinally displaceably with respect to the connecting piece in a simple manner. This longitudinally displaceable arrangement of the support base with respect to the connecting piece is required not only for adapting to different dimensions of storage containers in the axial direction but also for the simple production of the axial play required for exchanging the storage container.

For supporting the storage container on the holder in the area of the wings of the tray is according to one Training according to the invention between the slide and the guide rail a spring arranged. The spring can be designed as a tension or compression spring his. It acts on the slide with respect to the guide rail in the direction the connector.

According to another advantageous Embodiment of the invention each have the connector of the holder and the counterpart of the storage container an axially aligned screw thread for screwing together on. By this measure will it be possible through the reservoir Introduce and depositing on the support base of the holder, at least in a wing of the Supported base is aligned axially and without the application of additional holding forces in an assembly position to hold at the counterpart comes into contact with the connector. By simply turning the storage container, it can be screwed together of counterpart and connector, so that one permanent but releasable Connection between storage containers and holder is created. It is also conceivable that the A bayonet connection occurs in place of the screw connection. Either when using a screw connection as well as when using a bayonet connection Connector and counterpart so complementary to each other be trained that at Screwing or making the bayonet connection at the same time the fluidic connection between the connector and the reservoir, that is fluidic connection between the gas line and the interior of the Reservoir, will be produced. Pressurized carbon dioxide can then from reservoir flow to the mixing chamber. The establishment of this fluidic connection when attaching the reservoir can take place, for example, in that a corresponding functional element of the connector in the counterpart arranged valve in the opening direction actuated, with a constant application to maintain the valve opening of the valve is required by the functional element. It is alternatively also possible that in the connector one Hollow needle is arranged, which is designed for this purpose a sealing surface of the reservoir pierces. It is it is preferably provided that the production of the fluid Connection only takes place if it is ensured that the connection between connector and counterpart the pressure forces occurring when establishing the connection are not resolved more unintentionally becomes.

According to a preferred embodiment is the connector on the high pressure side trained on a pressure reducer.

By forming the connector directly the line length, which is subjected to high pressure, is at the pressure reducer is reduced to a minimum. At the same time, by adjusting the pressure reducer to a suitable one Adjust the concentration of the in the drinking water at the same time dissolved Carbon dioxide adapted to the needs become.

According to a further embodiment the holder of the invention can be attached to a wall. Through the Fastening the holder to the wall becomes an independent arrangement the holder of the mixing device allows, at the same time is a fixed Connection to a wall makes it particularly accident-proof a corresponding pressurized storage container.

For example, the holder is of an angle on a building wall or directly on the housing screwed onto the device.

The invention is described below of an embodiment shown in the drawing; it demonstrate:

1 : a schematic representation of a device for enriching piped drinking water with carbon dioxide;

2 : a perspective view of a holder according to the invention with a storage container arranged thereon;

3 : a tray according to the invention in perspective; and

4a to 4d : the placement or removal of a storage container in or from the holder.

The 1 shows a device 10 for enriching piped drinking water with carbon dioxide. The construction would be essentially identical when enriched with another water-soluble gas, for example oxygen. The drinking water is supplied via the supply line 11 a mixing device 17 fed. In the mixing device 17 is formed a mixing chamber, in the mixing device 17 further devices for carrying out the enrichment can also be provided. The carbon dioxide becomes the mixing device 17 over the gas pipe 12 from the reservoir 15 fed. With the storage container 15 is a conventional CO ₂ bottle. In the area of the gas pipeline 12 is a pressure reducer 28 , for example, a reducing valve arranged on the part of the reservoir 15 The high pressure provided is reduced to DIN pressure, which is used to enrich the drinking water with the carbon dioxide in the mix mer is needed.

From the mixing device 17 or from the mixing chamber in the mixing device 17 leads the tap line 13 to the tap 14 , In the tap line 13 the drinking water enriched with carbon dioxide is led. At the tap 14 this can be removed in portions, for example by the glass, for example on a tap or on a correspondingly designed fitting.

The 2 shows a perspective view of a holder 20 with a storage container held in it 15 ,

On the holder 20 are a pressure reducer 28 and a fitting formed thereon 21 arranged. The connector 21 there is a supporting floor opposite 22 on the holder 20 arranged. The supporting floor protrudes 22 at right angles from a sled 25 from that axially along a pair of guide rails 24 of the holder 20 is slidably mounted. Between a guide rail 24 and the sledge 25 is a feather 26 arranged the sledge 25 and thus also the supporting floor 22 towards the connector 21 with force. The keeper 20 is over a flange 19 on a wall or on the housing of the mixing device 17 fixable. The guide rails 24 are axially parallel to the axial alignment of the connector 21 and wings 23 of the tray 22 educated. The reservoir 15 is in the holder 20 on the one hand via the connector 21 and on the other hand via a wing 23 of the tray 22 held. Here is the reservoir 15 on the supporting floor 22 held both axially and laterally.

The 3 shows a supporting floor 22 , It has two wings 23 different outside diameter. The two wings 23 are essentially ring-shaped and aligned concentrically to each other. They are basically in the direction of displacement of the supporting floor 22 axially offset. The axial offset AV is chosen so that the web formed by this axial offset 18 has a height which is so great that the on the inner axial wing 23 supported storage container 15 laterally through the bridge 18 is led. For this purpose, the web points 18 a clear width L1 or L2, which corresponds to the outer diameter of a corresponding storage container 15 equivalent. If the reservoir 15 has a curved surface at its end on the supporting floor, can be formed by correspondingly curved supporting surfaces 23 not just an axial support of the storage container 15 but also an axial alignment and lateral support of the storage container 15 be achieved.

2 shows a reservoir 15 , which is large-volume and has a large outer diameter. Hence the reservoir 15 through the axially the connector 21 closer outer wing 23 of the tray 22 supported and laterally by the outer web 18 guided. The in the 4a to 4d shown smaller volume gas bottle, which as a storage container 15 serves, however, is on that of the connector 21 axially distant inner support ring 23 is supported and laterally by the inner web 18 led the inner wing 23 limited radially outwards and the axial offset AV between the two wings 23 generated, led.

The correct axial distance between the deck 22 and the connector 21 by moving the carriage axially 25 along the guide rail running parallel to the axis 24 reached. It should be noted here that the smaller-volume gas bottle, which has a smaller outside diameter, is the smaller storage container 15 , Can have a smaller axial length than a larger volume, larger diameter gas bottle, as for example in the 2 is shown.

The 4a to 4d show different steps in the process of inserting and connecting a storage container 15 in the holder 20 with the connector 21 ,

The 4a shows the insertion of a filled storage container 15 , like a gas bottle, in the holder 20 , The reservoir 15 becomes obliquely on the corresponding wing 23 of the tray 22 placed. The supporting floor becomes against the action of the spring 26 axially downward from the connector 21 pushed away so that the counterpart 16 of the storage container 15 under the connector 21 can be pushed and then aligned axially to this. Under the action of the spring 26 becomes the supporting floor 22 load-bearing, in the guide rails 24 guided sledge 25 back towards the connector 21 emotional. This causes the counterpart to move 16 a bit into the connector 21 in until the thread 27 of the counterpart 16 in engagement with a corresponding thread of the connector 21 device. The reservoir 15 is thereby axially aligned and already in the holder 20 still kept loose. Now that is in the 4b shown position reached and by turning the reservoir 15 becomes a screw connection between the counterpart 16 and the connector 21 manufactured. The connector 21 is directly on the pressure reducer 28 trained, which in turn on the holder 20 is arranged. By appropriate design of the connector 21 is the fluidic connection between the reservoir over the stroke during the last turns of the two threads against each other 15 and the high pressure side inlet of the pressure reducer 28 manufactured on the pressure-reduced outlet side with the gas line 12 connected is. The reservoir is in this position 15 securely in the holder 20 kept and protected.

After emptying the storage container 15 can this be according to the in the 4c and 4d procedure shown again by the holder 20 be removed. First, as in 4c ge shows, by rotating the storage container 15 in the corresponding direction of rotation, the screw connection between the counterpart 16 and the connector 21 solved again. The fluid connection between the storage container 15 and the pressure reducer 28 is separated from each other again during the first loosening screw turns and the storage chamber of the storage container 15 fluidically closed again. As soon as the screw connection is completely loosened, the reservoir becomes 15 axially from the connector 21 led away until the guide effect of the connector 21 opposite the counterpart 16 is ended. This is the sled 25 that the supporting floor 22 carries, again axially from the connector 21 moved away. This movement takes place against the force of the spring 26 , so that this shifting movement after removing the storage container 15 is reversed automatically.

The reservoir 15 can now, as in the 4d shown, can be removed from the side, the system of the guide container 15 on the corresponding wing 23 the tray is loosened. The keeper 20 is now ready to accommodate a new storage container 15 ready.
