Description

The The invention relates to a device for descaling a water spout.

By the DE 297 10 596 U1 a device for descaling a water spout has become known, which is elastic and is suitable for application to the, located at the free end of the water outlet mouth, for receiving a certain amount of water, and a soluble descaling agent therein. The stocking tube shown there consists of a plastic material which forms a container with an interior space for receiving a descaling agent to be dissolved, wherein an upwardly pointing overflow is arranged on the container.

The named DE 297 10 596 U1 has the disadvantage that the arrangement is formed in two parts and consists of an elastic, the water outlet cross-connection sleeve, in the lower mouth in the sliding seat, a plastic tube is inserted sealingly. This connection involves the risk that when filling the U-shaped tube, this slips out of the connection sleeve and sprayed the Entalkalkerflüssigkeit. Because of the design of this tube as a U-tube there is the further disadvantage that when filling an undesirable torque is exerted on the sliding seat of the connection sleeve, which could affect the strength of the sliding seat.

By opening the associated valve for the Water spout becomes this container filled with water and in the container existing descaling tablet is dissolved and from this a corresponding decalcification educated.

The decalcification So it works around the water outlet and decalcifies it.

disadvantage However, the known arrangement is that for a removal of air is not taken care of and that the arrangement otherwise not reliable is working.

After this first the bag-like Container firmly attached to the (still dry) water spout and sealed sealed then the faucet will be opened afterwards. But this is air in the container one and a little water. For one Air removal is not taken care of. That is, the whole arrangement works not because only an air-water mixture or air alone in the container is initiated, resulting in insufficient dissolution of the decalcifying tablet comes.

In addition, can the liquid level can not be controlled, which is about the water spout around should extend. fills the user inputs more water and exceeds the bursting pressure this container, Then it comes to the bursting of this container and the Entkalkerflüssigkeit can turn into dangerous Propagate way in the environment. There is an absolute risk of accidents.

The same danger exists when removing the container, because this may under overpressure stands. Is therefore the ring or the closure with which the container on Water outlet is attached, removed, initially escapes the overpressure and tears descaling with, causing severe burns on the skin of the user can.

Otherwise it is the installation of the known Entalkalkervorrichtung extraordinarily complicated, because it is difficult, the bag or baggy container to loop around the water spout and hold on while with the other hand, the corresponding locking device is actuated.

With the subject of DE 42 06 333 C1 is another descaling known, in which already a rubber-elastic container is wrapped around the water outlet and is also closed with a closing strap or a closing clamp around the water pipe around.

Also Here there is the disadvantage that is not provided for a vent. It therefore the container, in which the Entkalkertablette is arranged to be filled only insufficient. The rubber-elastic container is the rest the shape of the water spout essentially adapted what with associated with the disadvantage that only certain types of water outlets descale can be.

Another Disadvantage exists - as well as in the aforementioned DE-90 15 998 - that even in overcrowding This device tends to burst and the decalcifying liquid in dangerous Way in the environment can be splashed.

As well the assembly is difficult and expensive, because yes a corresponding Clamp or a sealing band for closing the rubber-elastic device is used on the water outlet pipe.

Otherwise it is the holder of the decalcifier at the water outlet not Reliable, because the rubber-elastic container is only one guided on the inner edge of the tube Tether fastened with a clamp surrounding the water outlet.

Will overpressure in the descaling tank initiated, then this tends to expand and down From the water outlet slide, what by the inner radius of the Water outlet held fastening tape is not prevented.

Already even at low pressure so will the decalcifier tank From the water outlet pull down and the entire holding device can not prevent this.

The said decalcification device is thus dependent on that the container always only under such low pressure filled it will not happen that its slipping from the water outlet. This requires a considerable attention of the operator.

Of the Invention is the object of a decalcifier versatile, suitable for all types of water outlets is and that works reliably.

The solution The object is achieved with the device according to claim 1. It is essential that the decalcification device essentially off a stocking tube, which material integral with a container for the Recording of the to be solved Descaling agent is connected to at least the hosiery tube made of a rubber-elastic material, e.g. Latex, exists and that on the container an outward directed overflow is arranged.

With the given technical teaching gives the essential advantage that now the entire device consisting of hosiery and container - in the a decalcifying agent is used - as a rubber-elastic tube Simply put on the water outlet. Due to the rubber elasticity of the stocking tube and the adjoining one container surrounds the device allows the water outlet completely and tightly, without any further Fasteners required. In particular, in the publications fasteners shown in the prior art such as Clamp or Velcro straps omitted.

Important is namely, that an overpressure in the container, in which the Entkalkermittel is arranged, is absent and is avoided. In fact, according to the invention the top of the container an overflow arranged in liquid-conducting Connection with the interior of the container is.

In order to be taken care that when refilling of the container with water first the air from the container Escapes, without this inflates and possibly exceeds its bursting pressure.

It So first from the overflow according to the invention the air escapes, until then the container rising from bottom to top can be filled with water from the water spout, as long as until the now forming decalcifying agent in drop form from the overflow emerges. This is a sign to the user that he is the one Refilling the container can now adjust because the descaling agent is now completely the Water outlet lapped and another padding is no longer necessary.

In order to results in a particularly reliable operation, without there is ever a risk that the container tends to burst.

It is preferred here, if the shape of the container so chosen is that the container has a Recording room for the decalcifying agent is formed. This means that the container may be may be preformed to a corresponding spherical or cylindrical shape train.

If however, other container shapes used, in particular rubber-elastic the water spout perfectly enclose, is intended according to the invention in a another embodiment yet a clamping device can be used.

In this case will be first the rubber-elastic container tight around the water spout around, where in the container Descaling agent is arranged.

To corresponding opening the water outlet fitting flows now first Air in the container, the above escapes the overflow of the invention. The then entering water fills the container on. However, it may be that in the container too low a filling volume arises. For this purpose it is envisaged that in the area of the overflow a clamping device is arranged, which temporarily this overflow close can.

The further into the container inflowing water will then be in the container Dammed, then slightly expands until the desired liquid volume in the container is reached.

To corresponding exposure time of the descaling agent around the water outlet around is then first removed the clamping device, which then the pressurized Water targeted from the overflow is derived down without the risk that this Agent sprayed in the area. Then it is with the water from the Flushed water outlet, until the entire device is free of descaling agent and can be removed without risk.

One such rinse was not possible with the arrangements according to the state of the art and led Therefore, a considerable risk of accident when dismantling said Devices.

In In a preferred embodiment, the decalcifier is the Descaling of all existing water outlets suitable for water fittings.

In In another embodiment, it is provided that the decalcifier also for decalcifying shower heads is determined.

It it performs the same function as in the decalcification of water outlets, only that during the decalcification of a shower head the overflow above the shower head is arranged while in the case of the formation of the decalcifier for descaling of water outlets the overflow above the so-called pervator is arranged.

By the arrangement of the overflow At the decalcification should be ensured in both cases that a preferably size Area of Water outlet or the shower head of the decalcifying liquid bathes is used to a large-scale decalcification over the reach entire part.

It may otherwise for safety reasons the decalcification of a shower head are provided, that ensured is that the shower head is not on the usual shower head holder in the shower tray during the descaling process should be maintained.

To For this purpose, the invention provides that the decalcifier still a so-called ground stand is assigned, which ensures that the shower head with the turned up Descaling device stored only on the floor of the shower tray is and not in the usual shower head holder is inserted.

One Such ground stand thus prevents the insertion of the with the Descaling equipped Shower head and ensures that this is no longer plugged into the conventional holder can be. Otherwise, could namely, it happen that the shower head with the attached decalcifier in the conventional Cradle is plugged into the shower tray and an unsuspecting User the shower in conventional Want to use way, in which case the escaping from the overflow descaling agent could hurt the user.

The By the way, tripod takes care for one essential horizontal arrangement of the shower head, with the aim of that the overflow always stays on top of the shower head and the shower head remains does not unintentionally turn, causing the descaler liquid could expire.

in the The following is the invention with reference to several execution paths illustrative drawings closer explained. Here are more from the drawings and their description Features and advantages of the invention.

It demonstrate:

1 : Schematisiert on average the attachment of a decalcifier at a water outlet

2 : The front view after 1

3 : Schematisiert a section through the attachment of the decalcifier to a shower head

In 1 and 2 is generally a water outlet 1 shown, consisting of a multiply bent tube 2 consists, at the front free end of a so-called pervator 3 The bottom is through a sieve 4 is closed. From the mouth 5 then the water flows out.

It should now the water outlet 1 in the area of its mouth 5 and around the pervator 3 be decalcified. For this purpose, the decalcifier 6 to 1 and 2 used, which consists essentially of a rubber-elastic stocking tube 7 which is sealing and tight due to its rubber elasticity on the pipe 2 is put on. The slipping may create a closing edge 9 that of the additional sealing and attachment of the hosiery 7 on the pipe 2 serves.

In this way it is ensured that the stocking tube 7 over a considerable length on the pipe 2 can be wound up and the length is easily changeable, because the flow edge 9 can be everted in any way, so that easily the length of the hosiery 7 can be changed accordingly.

Firm with the hosiery and as material einstückig is the container 8th connected to this, so that overall results in a one-sided elastic stocking. It is therefore a condom-like arrangement, so that is the container 8th firmly with the stocking tube 7 forms a single part.

In the interior of the container 8th is preferably a descaling agent 12 arranged or will be there before Assembly of the decalcifier 6 on the water outlet 1 introduced, which decalcifying agent 12 for example, from a decalcifying tablet, a pill or a liquid descaling agent, which is arranged in a corresponding packaging, but which can be blown by finger pressure may exist.

As soon as the decalcification device 6 in the in 1 and 2 way shown on the pipe 2 is deferred, now the water outlet of the valve can be opened and it flows first air into the interior 10 of the container 8th , This air escapes upwards through one at the top of the container 8th arranged overflow 15 that has a spout 14 fluid-conducting with the interior 10 of the container 8th connected is.

The air then flows through a pipe 16 down into the area.

The following water now fills the container 8th to the liquid level 13 on, the decalcifying agent 12 is dissolved in the water bath. An overfilling of the container 8th is not possible because a filling level above the liquid level 13 over the overflow 15 in drops 17 flows out of the device.

The user can now determine exactly how far the container 8th may fill up in order to achieve a concentrated descaling liquid as possible.

At the same time it prevents the container 8th is overcrowded and possibly from the pipe 2 triggers or even bursts.

In some cases, it may be provided that in the area of the pipe 16 a clamping device 18 is arranged. This clamping device consists of a simple clip or a spring with two spring legs, which are held spring-loaded in the closed position. Once this clamp 18 on the pipe 16 is attached, the tube is closed and the container 8th can also over the overflow 15 Be filled with water. This allows the volume in the interior 10 of the container 8th be enlarged.

In 1 is still shown that the tube 16 in the range of a plastic or rubber-elastic material existing support wall 19 the decalcifier 6 is guided.

In another embodiment, however, it may be provided that the support wall 19 not applicable and the pipe 16 cantilevered down on the upper side of the container 8th is arranged.

The 3 shows the application of the decalcifier according to the invention 21 in conjunction with a shower head 20 ,

In this case, the spout is 14 of the overflow 15 at the top of the shower head 20 arranged and the entire device is over the shower head 20 turned around, causing the in 3 shown use situation results.

For the same parts of the 3 Incidentally, the same terms apply as in the 1 and 2 ,

Advantage of the decalcifier 6 . 21 is that it is a low cost disposable, which is very easy to install, which can be rinsed after use and can then be disposed of accordingly.

Such descaling devices 6 . 21 Already with the descaling agent contained there 12 sold as a unit and mass-produced ready and are therefore easily applicable.

The The invention relates in summary to a device for descaling a water spout, which consists essentially of an elastic stocking tube which is with a container connected to receive the descaling agent, to which a outward directed overflow is arranged with connection to the environment or the drainage pipe. Essential here is that due to the elasticity of the hosiery and the adjoining one container the water outlet completely and is tightly enclosed without any further fasteners requirement. Through the overflow is guaranteed that no unwanted and impermissible overpressure in the decalcifier z. B. caused by air or water can. The decalcifier is inexpensive to produce, easy secure, and is suitable for all types of water outlets.
