Description

Ueing, Michael, Gartenstr. 25, 48329 Havixbeck "Device for treating water"

The innovation relates to a device for treating water according to the preamble of the claim

Such devices are also known as "limescale protection devices", in which each of the two windings is connected at one end to the electronic circuit, while the other end of each winding ends freely.

The innovation is based on the task of improving a generic device in such a way that the effectiveness of the device is improved.

This problem underlying the innovation is solved by the design according to the characterizing part of claim 1.

In other words, the innovation proposes not to allow the two windings to end freely, but to form a closed coil so that both ends of the two windings are connected to the electronic circuit. In this case, not only is an alternating voltage applied to each coil, but a direct voltage is superimposed on this alternating voltage. This achieves a more effective influence on the water, whereby not only is calcification of the pipes or fittings prevented, but the health compatibility (e.g. for the skin) and the taste properties of the water are also improved.

Advantageously, the water can be influenced by the two windings in two different stages, with the front coil in the direction of flow effecting a kind of pre-treatment of the water, while the rear coil effecting the final treatment of the water. Advantageously, a higher direct current voltage and a lower alternating current voltage can be applied to the rear coil.

In this case, the almost full supply current for the circuit can advantageously be conducted via the rear coil, so that no voltage reduction is required for the coil compared to the electronic circuit, which could impair the effectiveness and efficiency of the operation of this rear coil.

Further advantageous embodiments of the device according to the invention can be found in the subclaims.

The innovation is explained in more detail below using the drawing.

Fig. 1 shows schematically a device according to the invention, which is attached to a water pipe. and

Fig. 2 schematically shows the structure of the electronic circuit of the device of

Fig.1.

In Fig. 1, 1 denotes a pipe through which water flows. A device for treating the water has an electronic

Circuit within a housing 2, whereby the circuit can be connected to a power supply using a cable 3 and whereby the circuit also has outputs for two coils 4 and 5. Furthermore, a red indicator lamp 6 and a green indicator lamp 7 are provided in the housing 2. The power supply can be provided by batteries, solar modules or by means of a power supply unit also by the public power grid.

Water flows through the pipe 1 in the direction of the arrow shown, so that in the flow direction of the water, coil 4 is the front coil and coil 5 is the rear coil.

Fig. 2 shows a schematic representation of the electronic circuit housed in the housing 2.

The connections for the supply voltage are designated 3a and 3b, which can be designed as a 17-volt direct current, for example. From connection 3a, the current runs to an electronic overload protection device 8 ("polyswitch"), to a diode 9 serving as a pole protection device, from there to the green indicator lamp 7, which can be designed as an LED, and from there through a resistor 10 and the coil 5 to ground, i.e. to connection 3b. The green LED 7 therefore indicates that the device is basically ready for operation due to an applied voltage.

A current path runs from the pole protection 9 to the terminal no. 4 of an integrated circuit 11, whereby the circuit 11 is used to generate a square wave voltage

Two further current paths run from the pole protection 9 on the one hand via a resistor 12 to connection no. 7 of the integrated circuit 11 and on the other hand directly to connection no. 8 of this circuit 11.

From terminal 7 of circuit 11, a current path runs through a resistor 14 to terminal 2 of circuit 11 and from terminal no. 2 through a capacitor 15 to ground. From terminal no. of circuit 11, a current path runs through a capacitor 16 to ground.

In the direction of current flow behind the diode 9, a current path runs via the red indicator lamp 6, which can also be designed as an LED, via a resistor 17, which on the one hand serves as overload protection and on the other hand serves to generate a voltage divider, to the connection 4a of the coil 4. If the coil 4 is not connected, there is a connection via a capacitor 18 to connection no. 3 of the integrated circuit 11, so that overall a very weak glow of the red light-emitting diode 6 is achieved, thereby indicating a malfunction.

However, if the coil 4 is connected, the current flows with almost no resistance through the coil 4 and then through the connection 4b and a resistor 19 to ground. The resistor 19 is the second resistor required for the voltage divider. It is much smaller than the resistor 17 and causes the zero point of the alternating voltage to be shifted to the positive. In this way, a directed magnetic field and a directed electrical

field in the water, which increases the effect of the device.

In the line to ground, the connections 5c and 5d are provided for the coil 5, whereby a pole protection 20 can also be provided here.

Two capacitors 21 can be provided to compensate for a supply voltage that is too high and thus provide overload protection. The residual ripple of the alternating voltage from the public power grid (if the direct current supply is not ensured by batteries, a solar module or the like) and the fact that the integrated circuit 11 draws different currents when charging and discharging cause the alternating voltage to be superimposed on the direct voltage, whereby the actual supply voltage, i.e. the direct voltage of approx. 17 volts, is passed through the two coils 4 and 5.

A resistor 22 is connected in parallel to the two connections 5a and 5b for the coil 5. This resistor 22 enables a current flow even when the coil 5 is not connected, so that when the operating voltage is applied, the green LED 7 can light up in any case and can indicate the basic operational readiness of the entire device.

A polarity reversal indicator can be provided between the two connections 3a and 3b, which comprises a diode 23 .as well as a light-emitting diode 24 and a resistor 25 . In this way, an erroneous reverse polarity of the circuit not only leads to the entire circuit not working, but also

Incorrect polarity is immediately indicated to the user, so that no time-consuming troubleshooting is required and the circuit can be connected immediately with the correct polarity.
