Description

Die Erfindung betrifft eine Vorrichtung zur Entfeuchtung und/oder Entsalzung von Bauwerken durch Schwingungsbeaufschlagung mit vorzugsweise gedämpften, hochfrequenten Schwingungen im Bereich von 141 kHz mit einer dem Bauwerk zugeordneten Sendeeinrichtung, die von einer Signalerzeugungseinrichtung beaufschlagbar ist, der ein Netzteil mit vorgeordnetem Netztrafo zugeordnet ist.The invention relates to a device for dehumidification and / or desalination of buildings by vibration with preferably damped, high-frequency oscillations in the range of 141 kHz with a building assigned to the transmitting device, the from a Signal generating device can be acted upon, a power supply with is assigned to upstream network transformer.

Eine Vorrichtung dieser Art ist aus der EP 0736 639 A1 bekannt. Vorrichtungen dieser Art sind zum Austreiben von Feuchtigkeit ohne die Notwendigkeit von Eingriffen in das Mauerwerk geeignet. Bei der bekannten Anordnung erfolgt die Ableitung der Feuchtigkeit aber trotz vergleichsweise hoher eingesetzter elektrischer Leistung vergleichsweise langsam und mit im Verlauf längerer Beaufschlagungszeiten abnehmender Geschwindigkeit. In ungünstigen Fällen kann die Abwanderung von Feuchtigkeit ganz zum Stillstand kommen und sich in eine Zuwanderung umkehren (Schwappeffekt).A device of this type is known from EP 0736 639 A1. Devices of this type are for expelling moisture without the Necessity of intervention in the masonry suitable. In the known Arrangement takes place the derivative of moisture but despite comparatively high electrical power used comparatively slowly and with im Course of longer admission times of decreasing speed. In unfavorable cases, the exodus of moisture can be quite to Come to a standstill and turn back to immigration (Schwappeffekt).

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß eine Steigerung der Entfeuchtungswirkung erreichbar ist. On this basis, it is the object of the present invention, a device of the type mentioned with simple and inexpensive To improve means so that an increase in the dehumidifying effect is reachable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Netztrafo für die Abgabe einer vom Netz galvanisch getrennten Spannung eingerichtet ist und daß das Netzteil zwei Gleichspannungsausgänge für Plus und Minus aufweist, die wahlweise mit wenigstens einem dem Bauwerk zugeordneten, in die Erde einbringbaren Leiter verbindbar sind, wobei jeweils nur der eine Potentialsenke gegenüber dem Erdpotential der Umgebung ergebende Ausgang des Netzteils aktiviert ist.This object is achieved in that the power transformer for the delivery of a voltage isolated from the mains is established and that the power supply has two DC outputs for plus and minus having, optionally with at least one building associated, can be connected to the earth introducible conductor, in each case only the one Potential sink resulting from the earth potential of the environment Output of the power supply is activated.

Die in einem Mauerwerk vorhandene Feuchtigkeit enthält von den gelösten Salzen stammende Ionen, an die sich Wasser anlagert. Diese Teilchen, die durch die ausgesandten Schwingungen angestoßen werden, werden durch die mittels des in die Erde eingebrachten Leiters und mittels der galvanischen Trennung der Ausgänge des Netztrafos vom Netz geschaffenen Potentialsenke angezogen. Es kommt daher in vorteilhafter Weise zu einer zur Potentialsenke hin gerichteten Wanderung der durch die Schwingungsbeaufschlagung angeschobenen Ionen mit Hydrathülle, das heißt die Schwingungsbeaufschlagung untersützt die gerichtete lonenwanderung und damit die gerichtete Abwanderung der von den lonen mitgeführten Feuchtigkeit. In vorteilhafter Weise reicht dabei bereits eine vergleichsweise kleine elektrische Leistung aus. Sogenannter Elektrosmog ist daher in vorteilhafter Weise nicht zu befürchten. Trotz der vergleichsweise kleinen elektrischen Leistung sind eine schnelle und bleibende Entfeuchtung gewährleistet. Dadurch, daß das Netzteil zwei Gleichspannungsausgänge für plus und minus aufweist, ist eine Umschaltung der Potentialsenke von plus auf minus und umgekehrt und damit von einer Wirkung als Anode auf eine Wirkung als Kathode und umgekehrt möglich. Dies ermöglicht in vorteilhafter Weise eine Anpassung der erfindungsgemäßen Vorrichtung an das angetroffene bzw. sich ändernde Erdpotential sowie an die vorhandenen lonenzustände und gewährleistet damit eine universelle Verwendbarkeit sowie einen hohen Wirkungsgrad mit Langzeitwirkung. The moisture contained in a masonry contains of the dissolved Salts derived from ions, to which water accumulates. These particles, the are triggered by the emitted vibrations are through by means of the conductor introduced into the earth and by means of Galvanic isolation of the outputs of the mains transformer from the mains attracted potential sink. It therefore comes in advantageous Way to a potential sink towards directed by the Vibration of pushed ions with hydration shell, the means the vibrational loading supports the directed migration and thus the directed exodus of the ions entrained moisture. In an advantageous manner, already a sufficient comparatively small electrical power. So-called electrosmog is therefore not to be feared in an advantageous manner. Despite the comparatively small electrical power is a fast and permanent dehumidification guaranteed. The fact that the power supply two DC outputs for plus and minus, is a switch of the potential well of plus to minus and vice versa and thus of an effect as an anode on one Effect as a cathode and vice versa possible. This allows in an advantageous manner Way an adaptation of the device according to the invention to the encountered or changing ground potential and the existing ion states and thus ensures a universal usability and a high efficiency with long-term effect.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. So kann jedem Gleichspannungsausgang des Netzteils zweckmäßig ein Festspannungsregler zugeordnet sein, der auf einen Wert von ± 15V eingestellt ist. Eine Spannung von ± 15V ist als Maximalwert ausreichend, um eine wirksame Potentialsenke zu schaffen. Gleichzeitig ist hierdurch sichergestellt, daß hauseigene Sicherheitsschalter nicht ansprechen und damit Störungen unterbleiben.Advantageous embodiments and expedient further developments of the parent Measures are specified in the subclaims. So can each DC output of the power supply expedient one Fixed voltage regulator assigned to a value of ± 15V is set. A voltage of ± 15V is sufficient as maximum value, to create an effective potential sink. At the same time this is ensured that in-house safety switches do not respond and so that interference is avoided.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, daß ein an den in die Erde einbringbaren Leiter und an die beiden Gleichspannungsausgänge des Netzteils angeschlossener Umschalter vorgesehen ist, mittels dessen jeweils eine Verbindung des Leiters mit dem einen oder anderen Gleichspannungsausgang des Netzteils schließbar ist. Diese Maßnahme erleichtert die Umpolung der Potentialsenke von Plus auf Minus und umgekehrt.Another appropriate measure may be that a to the in the earth introducible ladder and the two DC outputs of the power supply of connected switches is provided, by means of which in each case a compound of the conductor with the one or the other DC voltage output of the power supply can be closed. This measure facilitates the polarity reversal of the potential sink from plus to Minus and vice versa.

Zweckmäßig kann dem in die Erde einbringbaren Leiter ein Spannungsregler zugeordnet sein, mittels dessen der Betrag der den Leiter beaufschlagenden Spannung einstellbar ist. Hierbei ist es möglich, vom Maximalwert von 15V nach unten abzuweichen, was eine Anpassung an die Verhältnisse des Einzelfalls ermöglicht. Gleichzeitig ist es in vorteilhafter Weise möglich, den Umschalter in den Spannungsregler zu integrieren, was eine einfache Bauweise ergibt.Suitably, the conductor can be introduced into the earth, a voltage regulator be assigned, by means of which the amount of the conductor acting Voltage is adjustable. Here it is possible to get from the maximum value of 15V to deviate downward, which is an adaptation to the circumstances of the Individually possible. At the same time it is possible in an advantageous manner, the Switch to integrate into the voltage regulator, which is a simple Construction results.

In weiterer Fortbildung der übergeordneten Maßnahmen kann der Leiter aus nicht rostendem, elektrisch leitendem Material, vorzugsweise aus nicht rostendem Stahl bestehen. Dies gewährleistet eine einfache Herstellbarkeit sowie eine lange Lebensdauer. In further training of the higher-level measures, the head can stainless, electrically conductive material, preferably not Consist of rusting steel. This ensures easy manufacturability and a long life.

Zweckmäßig kann der Leiter als lotrecht in die Erde einschlagbarer Spieß ausgebildet sein. Dies gewährleistet eine einfache Montage.Conveniently, the conductor can be used as a spit which can be punched vertically into the earth be educated. This ensures easy installation.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, daß der Leiter aus mehreren, vorzugsweise durch eine Schraubverbindung aneinander ansetzbaren Teilen besteht. Hierdurch ist es auf einfache Weise möglich, die Gesamtleiterlänge so zu wählen, daß sich ein Widerstand von höchstens 1 kQ ergibt. Gleichzeitig gewährleistet die einfache Verlängerbarkeit des Spießes, daß auch bei vergleichsweiser großer Gesamtspießlänge die freie Knicklänge beim Einschlagen vergleichsweise gering bleibt.Another appropriate measure may be that the head from several, preferably by a screw together attachable parts. This makes it possible in a simple manner, the Total conductor length to be chosen so that a resistance of at most 1 kQ results. At the same time, the easy extensibility of the Spießes that even with comparatively large total skewer length, the free Buckling length when driving comparatively low.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous embodiments and expedient developments of Parent measures are in the remaining subclaims and from the following example description on the basis of Drawing closer.
