Description

object The present invention is an apparatus for the treatment of especially drinkable liquids according to the preamble of claim 1.

Such a device is with the going back to the same assignee DE-GM 202 18 674 known.

It should the entire disclosure content of the aforementioned utility model be included in the content of the present patent application.

At the Subject of this utility model was the disadvantage that the for the transmission of Information used material (eg crystals) in an approximately cylindrical, broken cartridge was arranged, which of the flow medium flows around has been.

The transfer of information from the crystals in the interior of the cartouche were arranged on the flowing around However, water was insufficient. The water had to enter through the holes in the cartridge, the crystals arranged in the interior and other information bodies flow around then leave again and leave the housing in refined form.

The US 5800708 A discloses a method and a filter cartridge for the treatment / activation of water by means of crystalline tourmaline in the form of granular sintered material. The preparation / activation is piezoelectric and pyroelectric effects of tourmaline crystals, as well as in the water thereby produced excess isolated Hydroxil ions (H ₃ O ₂₎ ^- causes and causes emulsification, cleaning and permeation of water.

The DE 202 03 596 U1 discloses a device for cleaning and revitalizing treatment of the device flowing through liquids, and in particular of drinking water, wherein in the liquid flow at least one flow disk is arranged, which is connected to at least one information body (in particular silicon crystal mixture, ceramic particles, metal grit, chips, salts or homeopathic globules) , and wherein the liquid diverted by the flow disk in the radial direction at least partially flows around the information body arranged there.

The DE 88 11 055 U1 discloses a drinking water filter cartridge, which is located in a housing consisting of two joinable parts, the upper part has a screw threaded connection and the lower part at the bottom of a perforated bottom, the filter cartridge of a mateable, two-piece, with perforated bottom and Hole-covered vessel is filled with silver-containing activated carbon (grain size in particular between 0.1 to 2.5 mm), which is located between systems of carrier, filter and membrane materials, whereby a filter column is present, from bottom to top like is constructed following. In the lower part of the vessel of the filter cartridge, which includes the full height of the filter column, the height and diameter of the vessel is determined by the inner dimensions of the filter cartridge housing between the spacer lines, located on the hole bottom hole plate made of vulcanized fiber or plastic coated fabric, overlying one Microporous synthesis fabric disk, the outer dimensions of which corresponds to the internal dimensions of the filter cartridge vessel lower part, overlying a further same synthesis fabric disk, and heaped up to the full height of the vessel lower part, a silver-containing activated carbon. In the upper part of the vessel of the filter cartridge whose inside dimension corresponds to the outer dimension of the vessel of the filter cartridge and the height of which corresponds to a height of between 30 and 50% of the height of the vessel lower part, there is a perforated disc made of fabric-reinforced silicone rubber on the perforated lid, overlying a water-permeable membrane made of chemically- Synthetic material, with the same dimensions, overlying a disc of microporous synthetic tissue, wherein the vessel upper part so equipped is placed on the filled vessel bottom, completing and closing the filter cartridge.

Of the The invention is therefore based on the object, a device of educate the aforementioned type so that a much better information transfer can be done on the particular drinkable liquids.

As well the efficiency of the device should be increased overall.

to solution the object is the invention characterized in that that in the interior of the device downstream of a flow disk a receiving space is arranged, at least partially with a Coarse granules filled and that this coarse granules rests on a filter bag that filled with a fine granulate is. It is preferred that the liquid is under tap water pressure flows through the device.

With the given technical teaching, there is the significant advantage that now a much larger surface of information-providing substances in the interior of the housing can be arranged and that thus the contact surfaces with the particular drinkable liquid to a essential dimension is multiplied.

By the combination of information-giving granules in the form of Coarse granules in the flow direction sit on an underlying filter bag, which in turn filled with a fine granulate is, the more substantial advantage that results in a very simple construction done. The liquid flows through first once the layer of coarse granules, then hits the bottom arranged filter bag, passes through this filter bag on his entire area and therefore flows through it the arranged in the filter bag fine granules. Then it flows like that refined and loaded with the information water - or a other drinkable liquid - from the casing out.

It It is also noted that it is preferred when the filter bag at least simply folded into the interior of the housing introduced so it flows through area to improve.

hereupon However, the invention is not limited. In another embodiment It may be provided that the filter bag unfolded in the interior of the housing is introduced and in a third embodiment, it can be provided be that the filter bag folded several times arranged in the interior of the housing is.

In order to the filter bag is not flushed out of the bottom of the housing, It is further preferred if downstream of the filter bag, a perforated disc is arranged, which are preferably secured in position with a Seeger ring in the housing is arranged. The perforated disc is preferably made of a metal material with a plurality of holes arranged therein, each one Hole has a diameter of about 1 to 2 mm.

Here it is preferred that the perforated disc convexly convex upward (upstream) built into the housing is.

A similar Mechanical layer protection is also used for the flow inlet above arranged flow disk proposed.

Also this flow disk rests on a ledge in the interior of the case and goes up secured with a Seeger ring, leaving the flow disk can not tilt or even dissolve out of the housing composite.

When Shaping for a housing is about a pear-shaped Cross-section preferred, wherein the housing is preferably formed in one piece is.

It has at its upper inlet end an internal thread, with the the housing in the outlet of a shower, a faucet or a other fluid-emitting Fitting, device or the like can be screwed.

At the Expiring points the housing preferably an external thread on, and thus the housing for example, can be screwed onto a shower head.

in the said embodiment therefore serves the housing for refining shower water to be in the intermediate area between the Shower hose and the shower head to be screwed.

hereupon However, the invention is not limited. This housing can also be screwed to the water outlet of a water outlet fitting.

Both embodiments are characterized by the fact that the housing with water under water line pressure flows through What ensures a very good flow performance.

Of course it is the invention is not limited to the refining of water, but it can all drinkable liquids also be grafted, provided they are either under relative high pressure or over a certain amount of time through the housing pass.

such drinkable liquids would be for example Mineral water, fruit juices and alcoholic drinks.

For example It is also envisaged that such a finishing device screwed to the pressure outlet of a siphon, which due to the high discharge pressure of the liquid from the siphon reaches a good flow through the housing becomes.

Of the Subject of the present invention does not arise only from the subject of the individual claims, but also from the combination the individual protection claims among themselves.

All Information and characteristics disclosed in the documents, in particular the spatial training shown in the drawings as claimed essential to the invention, as far as they individually or in Combination opposite the prior art are new.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further inventions essential features and advantages of the invention.

It demonstrate:

1 Fig. 1 schematically shows a section through a device according to the invention;

2 : one opposite 1 modified embodiment with a divisible housing;

3 : the perspective view of a flow disk;

4 : A schematic section through a filter bag with content (fine granules).

In 1 is an embodiment about an approximately pear-shaped housing 1 shown in cross-section, which preferably consists of a metal material. However, it is also possible, this case 1 to produce from a plastic material, which is produced for example by injection molding or in the hollow blowing process.

The housing 1 consists of top part 2 and lower part 5 , which are materially connected with each other, and carries on its underside a thread 3 with which it is screwed onto any hose, shower head or the like. In the embodiment shown, it is shown that the spout 19 of the housing 1 in a container 22 opens, where the refined liquid 23 accumulates in the ground area.

Of course, the invention is not on the arrangement of a thread 3 at the outlet 19 limited. It can be the thread 3 also omitted and the spout 19 can flow directly into the open air.

The approximately pear-shaped housing 1 therefore has an upper neck 4 on, which merges into a larger diameter cross section, on which an annular shoulder 12 is arranged, on which a flow disk 9 seated. The flow disk 9 gets up through a circlip 11 secured so that these are not from the seat 12 can lift off and tilt.

The structure of the flow disk 9 is in 3 shown in more detail. The flow disk consists on its underside of a number of evenly distributed around the circumference arranged vanes, which are out of the plane of the flow disk 9 are bent out and therefore slots 8th in the flow disk 9 define.

The vanes 7 are therefore as sheet metal tabs made of a sheet metal flow plate 9 pushed out and therefore form the said slots 8th ,

The vanes 7 are each outwardly directed in the radial direction and - as shown - evenly distributed on the circumference.

The number of vanes 7 is arbitrary. Three, four, five or more vanes can be evenly distributed around the perimeter.

Now as soon as a fluid to be refined in the housing 1 above the opening 18 in which an internal thread 13 is provided, it can pass through the flow disk 9 pass through and is thus preferred in the direction of arrow 14 swirled in the direction of flow. From the perspective of the opening 18 Thus, the Verwirbelungsrichtung is levorotatory preferred. This, a relatively high, turbulent swirl-containing liquid flow, is now in the bed of coarse granules 15 introduced, which in the interior of the housing 1 is arranged. The coarse granules 15 is thus flowed through under the highest surface contact. The thus prepared liquid then passes on the surface of a filter bag 17 in the embodiment shown, simply folded in the interior of the housing 1 is arranged.

This filter bag 17 is with a fine granules 16 filled and is schematized again on average 4 shown.

It preferably consists of a non-water-soluble paper material, which is finely perforated and therefore has a good flow-through effect. In the interior of the filter bag 17 is a fine granulate 16 arranged with such a grain size that it can not be flushed out of the perforations of the filter bag.

The paper material is at both ends 20 welded or glued, so a cheap production of such a paper filter bag 17 to ensure.

The invention is not based on the use of a paper filter bag 17 limited. Other materials can also be used, such as plastic films or plastic-paper composite films.

It is important that an excellent efficiency for the water to be refined or the drinkable liquid is given, with first a treatment by flowing through the bed of coarse granules 15 takes place and then a further, finer treatment by the flow through the filter bag 17 with the fine granules arranged there 16 he follows.

So the filter bag 17 and the entire granule assembly is not out of the housing 1 can be flushed out, is near the outlet 19 a perforated disc 6 arranged, which consists of a metal material and in which a number of holes are present, which are evenly distributed over the circumference. This perforated disc 6 should form the lowest possible flow resistance for the liquid flowing through and therefore has relatively large holes in the range of 1 to 3 mm.

It lies on an annular shoulder in the interior of the housing and is from above by a retaining ring 10 secured so that it can not fall out.

To the filter bag 17 in 4 It is also noted that the filter hull formed by the paper material 21 may also be formed of a different material, even of a metal material. This metal material is then perforated accordingly.

In 2 a modified embodiment is shown, in which it is shown that the housing 1 can also be in two parts, namely a top 2 exists, which can be screwed or plugged on a lower part 5 can be plugged or screwed on.

The same explanations then apply as with reference to 1 given.
