Description

The invention relates to a water pipe intermediate piece, with two connection points for one water pipe each, the two connection points being connected by an internal connection path for the water supply.

The connection points can in particular each be selected as at least one connection point from the group consisting of screw, bayonet, plug and / or clamp connections.

The invention is based on the object of creating a water pipe intermediate piece for use in a water pipe and / or for forming a section of a water pipe that has at least one additional function.

The object is achieved according to the invention by a water pipe adapter of the type mentioned at the beginning with the features of claim 1. In particular, according to the invention, a water pipe adapter of the type mentioned at the beginning is proposed to achieve the object, which is further characterized in that a sensor is arranged in the connection path which detects a property of the water in the connection path, that an acoustic output device is formed and that a control device is formed which is set up to control the output device as a function of a signal from the sensor. The water pipe adapter according to the invention thus makes it possible to use the output device to indicate a specific property to a user by means of an acoustic signal. An essential advantage of the water pipe adapter according to the invention is that it can be used in almost any water supply or water pipe of any design without having to modify a fitting, for example. It is thus possible to retrofit already existing water supplies with the water pipe adapter according to the invention by inserting it into a water pipe.

Advantageous refinements of the invention are described below which, alone or in combination with the features of other refinements, can optionally be combined with the features according to claim 1.

The named sensor can preferably be a temperature sensor in order to measure a water temperature of the water flowing through the internal connection path in the assembly position.

According to an advantageous development of the intermediate water pipe piece, the control device can have a memory unit in which voice messages to be output are stored. In particular, it can be a replaceable memory unit and / or a memory unit designed to store individual voice messages. The voice message can thus be set up in an application-related manner in order to be able to give a user better acoustic feedback on the state of the water.

As an alternative or in addition to this, the control device can have a data interface via which the content of the memory unit can be changed. It is thus also possible to be able to change the content of the storage unit subsequently, that is to say in particular after installing the intermediate water pipe, in order to be able to adapt the acoustic signal that can be reproduced via the acoustic output device. This is particularly advantageous if the built-in intermediate water pipe piece is difficult to reach or would first have to be removed again in order to gain access to the storage unit.

According to an advantageous development, it can be provided that the control device has a tone generator, in particular a speech generator. In this way, tones can be generated depending on the properties of the water.

According to a particularly advantageous development, it can be provided that the control device is set up to change an output language of a speech generator, in particular the speech generator already mentioned, in particular by configuration and / or programming.

In order to make the water conduit adapter self-sufficient, it can be provided according to an advantageous development that a generator that can be driven by the water in the connection path is configured, in particular for supplying the control device.

According to a further advantageous embodiment, at least one preferably adjustable threshold value for the signal of the sensor can be stored in the control device, the control device activating the output device when the threshold value is reached. The threshold value can therefore be used to determine when activation takes place, with parameters such as a length of a line section downstream of the water line adapter, in which, for example, heat from the water to the environment up to a water outlet, can be taken into account.

According to a further advantageous embodiment, it can be provided that a temperature and a volume flow of a hot water line can be measured and that a mixed temperature can be calculated with a computing unit from the temperature and the volume flow of the hot water line, in particular and additionally from the temperature and the volume flow of the cold water line comparable to a threshold value, for example the one already mentioned. The respective temperature can be measured, for example, with a sensor and the respective volume flow with a volume flow sensor.

The calculation of the mixed temperature can take place under approximate assumptions for a temperature and / or a volume flow in the cold water pipe.

Alternatively, a temperature and / or a volume flow of a cold water pipe can also be measured. Then the calculation can be done according to the known laws for the mixing temperature of two liquids.

The computing unit can for example be fed electrically from a generator which can be placed in the cold water pipe and / or in the hot water pipe. It is particularly advantageous if the generator is coupled to a volume flow sensor or a volume flow sensor is (also) used as a generator. This simplifies the structural design.

The threshold value can, for example, be 50 ° C. or another value above which there is a risk of scalding.

The invention further relates to the use of a water pipe adapter as described and / or claimed herein, the fitting being connected to a hot water connection, in particular to a boiler outlet and / or to a corner valve, characterized in that the water pipe adapter between the hot water connection and the valve is arranged. It is thus possible to integrate the water pipe adapter into an existing water supply in a particularly simple manner, without the other components having to be fundamentally changed or new components having to be used.

According to an advantageous development, the intermediate water pipe piece can be arranged closer to the hot water connection than to the fitting. This means that the properties of the water can be measured almost immediately after the hot water connection, which improves the measurement result in certain applications.

According to a further advantageous development, an output language can be selected and / or at least one threshold value can be set for the signal of the sensor before or during operation. Subsequent user-friendly configuration is thus possible.

According to a particularly advantageous development, several threshold values can be set up for at least one property. In particular, when one of the threshold values is reached, it can first be checked which of the threshold values has been reached, and the output device is activated as a function of which of the threshold values has been reached.

In one embodiment of the invention, it can be provided that a mixed temperature is calculated from a temperature and a volume flow of a hot water pipe and compared with a threshold value, for example the one already mentioned. This means that it is not necessary to record the temperature at one outlet of the fitting.

To improve the accuracy of the calculation, a temperature and / or a volume flow of a cold water pipe can also be used in order to calculate a mixed temperature, for example in a manner to be described in more detail.

The invention will now be described in more detail on the basis of several exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments result from the combination of the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiments.
