Description

Die Erfindung bezieht sich auf einen Verdunstungsluftbefeuchter mit einem Wasservorratsbehälter, mit einer Tragplatte, welche einen Verdunstungsfilter und eine in den Wasservorratsbehälter reichende Pumpe trägt, mit einem Ventilator, mit einem Motor zum Antreiben der Pumpe und mit einer Haube mit Luftein- und Luftaustrittsöffnungen, wobei der Motor an der Haube befestigt und zwischen Motor und Pumpe eine Kupplung vorgesehen ist, mittels welcher beim Abheben bzw. Aufsetzen der Haube automatisch die Verbindung lösbar bzw. herstellbar ist.The invention relates to an evaporative humidifier with a water reservoir, with a support plate which carries an evaporation filter and a pump reaching into the water reservoir, with a fan, with a motor for driving the pump and with a hood with air inlet and air outlet openings, the Motor attached to the hood and a coupling is provided between the motor and pump, by means of which the connection can be released or produced automatically when lifting or putting on the hood.

In dem DE-GM 75 06 266 ist ein Verdunstungsluftbefeuchter beschrieben, bei welchem ein Motor sowie der Ventilator an einem Deckel bzw. an einer Haube angeordnet sind. In den Wasservorratsbehälter des Verdunstungsluftbefeuchters ragt eine Pumpe, deren Antriebswelle mittels einer Steckkupplung mit der Welle des genannten Motors verbindbar bzw. lösbar ist. Der Ventilator befindet sich am oberen Ende des Verdunstungsfilters, wobei dort auch eine Flüssigkeitsverteilerrinne angeordnet ist, welcher mittels der Pumpe über einen Schlauch oder dergleichen das Wasser aus dem Wasservorratsbehälter zugeführt wird. Der bekannte Verdunstungsluftbefeuchter weist somit eine große Bauhöhe auf, da der Ventilator im Bereich des oberen Endes des Verdunstungsfilters angeordnet ist. Ferner wird aufgrund des Motors, welcher zwischen der Unterseite und dem Ventilator sich befindet, zusätzlich eine entsprechende Vergrößerung der Bauhöhe des Verdunstungsluftbefeuchters erforderlich. Ein derart ausgebildeter Verdunstungsluftbefeuchter ist somit sperrig, und es ist ein vergleichsweise großer Konstruktions- und Fertigungsaufwand erforderlich, damit der Verdunstungsluftbefeuchter und insbeondere dessen Haube die notwendige Festigkeit und die Steifigkeit aufweist. Es ist ersichtlich, daß hierdurch auch ein relativ hohes Gesamtgewicht bedingt ist.DE-GM 75 06 266 describes an evaporative air humidifier in which a motor and the fan are arranged on a cover or on a hood. A pump protrudes into the water reservoir of the evaporative humidifier, the drive shaft of which can be connected or detached to the shaft of said motor by means of a plug-in coupling. The fan is located at the upper end of the evaporation filter, a liquid distribution channel also being arranged there, and the water being supplied from the water storage container by means of the pump via a hose or the like. The well-known Ver Evaporative air humidifier therefore has a large overall height, since the fan is arranged in the region of the upper end of the evaporation filter. Furthermore, due to the motor, which is located between the underside and the fan, a corresponding increase in the overall height of the evaporative humidifier is required. An evaporation humidifier designed in this way is therefore bulky and a comparatively great outlay in terms of design and manufacture is required so that the evaporation humidifier and, in particular, its hood has the necessary strength and rigidity. It can be seen that this also results in a relatively high overall weight.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Verdunstungsluftbefeuchter der genannten Art derart auszubilden, daß bei einem vergleichsweise geringen Konstruktions- und Herstellungsaufwand eine niedrige Bauhöhe, d.h. ein geringer Abstand zwischen dem Boden des Wasservorratsbehälters und der Haube bzw. deren Oberkante erreicht wird. Ferner soll der Verdunstungsluftbefeuchter eine ordnungsgemäße Luftführung der durch die Lufteintrittsöffnungen über den Verdunstungsfilter angesaugten und mittels des Ventilators durch die Luftaustrittsöffnungen ausgeblasenen Luft gewährleisten.The invention is therefore based on the object of designing an evaporative air humidifier of the type mentioned in such a way that a low overall height, i.e. a small distance between the bottom of the water reservoir and the hood or the top edge is achieved. The evaporation air humidifier is also intended to ensure proper air flow of the air drawn in through the air inlet openings via the evaporation filter and blown out through the air outlet openings by means of the fan.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Motor und der Ventilator innerhalb eines im wesentlichen hohlzylindrischen Strömungskanales angeordnet sind, welcher sich von der Unterseite der Haube bis zumindest zum Ventilator erstreckt.This object is achieved in that the motor and the fan are arranged within a substantially hollow cylindrical flow channel which extends from the underside of the hood to at least the fan.

Der erfindungsgemäße Verdunstungsluftbefeuchter zeichnet sich vor allem durch einen einfachen Aufbau aus, wobei in einfacher Weise eine geringe Bauhöhe erreicht wird. Mittels des Strömungskanales wird ein ordnungsgemäßer Strömungsverlauf der durch die Lufteintrittsöffnungen mittels des Ventilators angesaugten und durch die Luftaustrittsöffnungen ausgeblasenen Luft sichergestellt. Die Bauhöhe des Verdunstungsluftbefeuchters wird somit einerseits durch die Höhe des Wasservorratsbehälters und somit durch das Speidiervolumen für Wasser und andererseits durch die notwendige Höhe des Verdunstungsfilters vorgegeben. Die Größe des Motors, des Ventilators, der Kupplung sowie der Pumpenwelle haben hingegen auf die Bauhöhe des Verdunstungsluftbefeuchters praktisch keinen Einfluß. Die letztgenannten Bauteile können somit je nach den Anforderungen ausgelegt und vorgegeben werden, ohne daß hierbei irgendwelche Kompromisse eingegangen werden müssen, um eine kleine Bauhöhe zu erhalten.The evaporation humidifier according to the invention is characterized above all by a simple structure, with a low overall height being achieved in a simple manner. The flow channel ensures a proper flow profile of the air sucked in through the air inlet openings by means of the fan and blown out through the air outlet openings. The overall height of the evaporation air humidifier is thus determined on the one hand by the height of the water storage container and thus by the volume of water being dispensed and on the other hand by the necessary height of the evaporation filter. The size of the motor, the fan, the coupling and the pump shaft, on the other hand, have practically no influence on the overall height of the evaporative humidifier. The latter components can thus be designed and specified according to the requirements without having to make any compromises in order to obtain a small overall height.

Bei einer bevorzugten Ausführungsform sind an der Unterseite der Haube und innerhalb des Strömungskanales Versteifungsrippen vorgesehen. Mittels dieser Versteifungsrippen wird einerseits die Stabilität und Festigkeit des Strömungskanales erhöht und andererseits wird die Luftströmung entsprechend beeinflußt, so daß Strömungsgeräusche oder Ventilationsgeräusche erheblich verringert oder vermieden werden.In a preferred embodiment, stiffening ribs are provided on the underside of the hood and within the flow channel. By means of these stiffening ribs, on the one hand, the stability and strength of the flow channel is increased and, on the other hand, the air flow is influenced accordingly, so that flow noises or ventilation noises are considerably reduced or avoided.

In einer bevorzugten Ausführungsform ist der Strömungskanal vom Verdunstungsfilter umgeben, bzw. der Strömungskanal ragt in den Verdunstungsfilter hinein, wobei die auf dem Verdunstungsfilter angeordnete Flüssigkeitsverteilerrinne im wesentlichen unmittelbar unterhalb der Unterseite der genannten Haube angeordnet ist. Somit kann der Strömungskanal in seinen Abmessungen ohne Schwierigkeiten auf die Anordnung und die Abmessungen des Ventilators abgestimmt werden, während der Verdunstungsfilter sowie die Flüssigkeitsverteilerrinne ihrerseits entsprechend dem geforderten Feuchtigkeitsdurchsatz ausgebildet werden können. Da die Flüssigkeitsverteilerrinne unmittelbar unterhalb der Unterseite der Haube angeordnet ist, wird auch insoweit eine niedrige Bauhöhe des Verdunstungsluftbefeuchters gewährleistet.In a preferred embodiment, the flow channel is surrounded by the evaporation filter, or the flow channel protrudes into the evaporation filter, the liquid distribution channel arranged on the evaporation filter being arranged essentially immediately below the underside of the hood mentioned. So can the dimensions of the flow channel can be matched to the arrangement and dimensions of the fan without difficulty, while the evaporation filter and the liquid distribution channel can in turn be designed in accordance with the required moisture throughput. Since the liquid distribution channel is arranged directly below the underside of the hood, a low overall height of the evaporative air humidifier is also ensured.

Vorteilhaft ist der Ventilator etwa auf halber Höhe zwischen der Tragplatte und der Unterseite der genannten Haube angeordnet. Mit anderen Worten, der Ventilator befindet sich etwa im Bereich der halben Höhe des Verdunstuigsfilters und es wird daher durch die Lufteintrittsöffnungen angesaugte Luft den Verdunstungsfilter weitgehend gleichmäßig durchströmen.The fan is advantageously arranged approximately halfway between the support plate and the underside of the hood mentioned. In other words, the fan is located approximately in the region of half the height of the evaporative filter and therefore air drawn in through the air inlet openings will flow through the evaporative filter largely uniformly.

In einer bevorzugten Ausführungsform erstreckt sich der Strömungskanal von der Unterseite der Haube bis in einen Bereich unterhalb des Ventilators. Somit ist in besonders einfacher Weise sichergestellt, daß auch im Bereich der Unterkante des Strömungskanales keine unzulässigen Wirbel oder Strömungen auftreten, welche einen ungünstigen Einfluß auf den Wirkungsgrad hätten.In a preferred embodiment, the flow channel extends from the underside of the hood to an area below the fan. This ensures in a particularly simple manner that no inadmissible eddies or flows occur in the area of the lower edge of the flow channel, which would have an unfavorable influence on the efficiency.

Weitere erfindungsgemäße Merkmale und Vorteile ergeben sich aus dem in der Zeichnung dargestellten und nachfolgend erläuterten Ausführungsbeispiel. Es zeigen:

  • Fig. 1 einen Querschnitt durch den Verdunstungsluftbefeuchter und
  • Fig. 2 einen vergrößerten Querschnitt von Kupplung und Ventilator gemäß Fig. 1.
Further features and advantages according to the invention result from the exemplary embodiment shown in the drawing and explained below. Show it:
  • Fig. 1 shows a cross section through the evaporative humidifier and
  • FIG. 2 shows an enlarged cross section of the clutch and fan according to FIG. 1.

Der Verdunstungsluftbefeuchter besitzt ein kastenförmiges Gehäuse, wie es in Fig. 1 dargestellt ist. Das Gehäuse besteht aus einem Unterteil in Form eines Wasservorratsbehälters 1 und einer Haube 2, zwischen welchen sich eine Tragplatte 3 befindet. Die Tragplatte-3 besitzt einen umlaufenden, im Querschnitt H-förmigen Rand, mit welchem sie auf dem Wasservorratsbehälter 1 aufliegt. Auch die Haube greift in den genannten H-förmigen Rand 4 ein, so daß ein nach außen dichter Abschluß gegeben ist. Auf der Tragplatte 3 ist ein Verdunstungsfilter 5 angeordnet, auf welchem oben eine Flüssigkeitsverteilerrinne 6 angeordnet ist. Die Tragplatte 3 besitzt einen nach oben gerichteten Ansatz 7, in welchen eine Pumpe 8 eingehängt ist.The evaporative humidifier has a box-shaped housing, as shown in Fig. 1. The housing consists of a lower part in the form of a water reservoir 1 and a hood 2, between which a support plate 3 is located. The support plate-3 has a circumferential, cross-sectionally H-shaped edge with which it rests on the water reservoir 1. The hood also engages in the H-shaped edge 4, so that there is a tight seal to the outside. An evaporation filter 5 is arranged on the support plate 3, on which a liquid distribution channel 6 is arranged at the top. The support plate 3 has an upward projection 7, in which a pump 8 is suspended.

Die Pumpe 8 enthält ein Gehäuse mit zwei Tragrohrhälften 9, 10 und einem unteren, topfförmigen Gehäuseteil 11. Die Pumpe enthält weiterhin eine Welle 12 mit einem hier nicht näher dargestellten Pumpenrad 13. Das Gehäuseteil 11 besitzt öffnungen 14, durch welche Wasser aus dem Vorratsbehälter 1 angesaugt und mittels des Pumpenrades 13 durch einen Schlauch 15 in die Verteilerrinne 6 befördert wird. Die Flüssigkeitsverteilerrinne 6 befindet sich unmittelbar unterhalb der Unterseite 18 der Haube 2, so daß der Verdunstungsfilter 5 eine große Höhe bzw. Oberfläche aufweist. Die Haube 2 weist an der Seite Lufteintrittsöffnungen 16 und oben Luftaustrittsöffnungen 17 auf. An der Unterseite 18 der Haube 2 ist ein schematisch angedeuteter Elektromotor 19 angeordnet. Die Welle des Motors 19 ist ebenso wie die Welle 12 der Pumpe 8 im wesentlichen vertikal angeordnet, wobei die genannten Wellen miteinander fluchten. Das untere Wellenende 20 ist aus dem Motor 19 herausgeführt und trägt einen Ventilator 21, wobei eine Nabe drehfest mit dem Wellenende 20 verbunden ist. Der Motor 19 sowie der Ventilator 21 befinden sich innerhalb eines weitgehend zylindrischen Strömungskanales 23, welcher ebenfalls an der Unterseite 18 der Haube 2 angeordnet ist und zweckmäßigerweise mit der Haube 2 aus einem einzigen Stück hergestellt ist. Im Inneren des Strömungskanales 23 befinden sich weiterhin Versteifungsrippen 24, durch welche auch eine Führung des Luftstromes bewirkt wird. Der vom Motor angetriebene Ventilator 21 bewirkt eine Luftströmung in Richtung der Pfeile 25 und 26, wobei beim Durchströmen des Verdunstungsfilters 5 das verdunstete Wasser mitgenommen wird. Der Ventilator 21 befindet sich bevorzugt etwa auf halber Höhe zwischen Tragplatte 3 und Unterseite 18 der Haube und somit etwa auch in halber Höhe des Verdunstungsfilters 5. Der Strömungskanal 23, welcher vom Verdunstungsfilter 5 unter Einhaltung eines vorgegebenen Mindestabstandes umgeben wird, endet in einem Bereich unterhalb des Ventilators 21. Es sei darauf hingewiesen, daß das Gehäuse in der zur Zeichenebene senkrechten Ebene einen kreisförmigen oder auch einen langgestreckten rechteckförmigen Querschnitt aufweisen kann. Aus diesem Grunde ist in Fig. 1 die linke Seite nur zum Teil dargestellt. Es sei weiterhin hervorgehoben, daß auf der Haube 2 sämtliche elektrische Einrichtungen angeordnet sind, also auch die hier nicht dargestellten Anschlußklemmen, Schalter usw. Somit wird gewährleistet, daß beim Abheben der Haube 2 sämtliche elektrische Einrichtungen von den übrigen Teilen des Verdunstungsluftbefeuchters getrennt sind. Zwischen Motor 19 und Pumpe 8 befindet sich eine lösbare Kupplung 30. Die Kupplung 30 besitzt eine erste Kupplungshälfte 31, welche an dem unteren Wellenende 20 angeordnet ist. Der Kupplungshälfte 31 ist eine zweite Kupplungshälfte 32 zugeordnet, welche mit der Welle der Pumpe 8 verbunden ist. Die Kupplungshälfte 32 enthält oder besteht aus einem Permanentmagnet, während die erste Kupplungshälfte 32 aus Weicheisen besteht. Die derart ausgebildete Magnetkupplung ist in der Weise dimensioniert, daß im aufgesetzten, dargestellten Zustand der Haube 2 eine sichere Verbindung zwischen Motor und Pumpe und somit auch ein sicherer Antrieb der Pumpe gewährleistet ist. Andererseits wird aber beim Abheben der Haube 2 die bestehende Verbindung gelöst, und zwar ohne daß von außen zusätzliche Handgriffe erforderlich wären. Da, wie oben bereits angegeben, in der Haube sämtliche elektrische Einrichtungen angeordnet sind, können dann der Wasservorratsbehälter 1, die Pumpe 8 . sowie Verdunstungsfilter 5 sehr leicht gereinigt werden. Es muß also lediglich die Haube abgenommen werden, um die Trennung der elektrischen Einrichtungen einschließlich Motor von den übrigen Teilen des Verdunstungsluftbefeuchters zu erreichen.The pump 8 contains a housing with two support tube halves 9, 10 and a lower, pot-shaped housing part 11. The pump further contains a shaft 12 with a pump wheel 13, not shown here. The housing part 11 has openings 14 through which water from the reservoir 1 is sucked in and conveyed by means of the pump wheel 13 through a hose 15 into the distribution channel 6. The liquid distribution channel 6 is located directly below the underside 18 of the hood 2, so that the evaporation filter 5 has a large height or surface. The hood 2 has air inlet openings 16 on the side and air outlet openings 17 at the top. A schematically indicated electric motor 19 is arranged on the underside 18 of the hood 2. The shaft of the motor 19, like the shaft 12 of the pump 8, is arranged essentially vertically, the shafts mentioned being aligned with one another. The lower shaft end 20 is led out of the motor 19 and carries a fan 21, one Hub is rotatably connected to the shaft end 20. The motor 19 and the fan 21 are located within a largely cylindrical flow channel 23, which is also arranged on the underside 18 of the hood 2 and is expediently made with the hood 2 from a single piece. In the interior of the flow channel 23 there are also stiffening ribs 24, through which the air flow is also guided. The fan 21, which is driven by the motor, causes an air flow in the direction of the arrows 25 and 26, the evaporated water being carried along when the evaporation filter 5 flows through. The fan 21 is preferably located approximately halfway between the support plate 3 and the underside 18 of the hood and thus also approximately half the height of the evaporation filter 5. The flow channel 23, which is surrounded by the evaporation filter 5 while maintaining a predetermined minimum distance, ends in an area below of the fan 21. It should be pointed out that the housing in the plane perpendicular to the plane of the drawing can have a circular or an elongated rectangular cross section. For this reason, the left side is only partially shown in FIG. 1. It should also be emphasized that all electrical devices are arranged on the hood 2, that is to say also the connecting terminals, switches, not shown here. This ensures that when the hood 2 is lifted off, all electrical devices are separated from the other parts of the evaporative humidifier. There is a releasable coupling 30 between the motor 19 and the pump 8. The coupling 30 has a first coupling half 31 which is arranged on the lower shaft end 20. The coupling half 31 is assigned a second coupling half 32 which is connected to the shaft of the pump 8. The coupling half 32 contains or consists of a permanent magnet, while the first coupling half 32 consists of soft iron. The magnetic coupling designed in this way is dimensioned such that a secure connection between the motor and pump and thus also a safe drive of the pump is ensured in the attached, illustrated state of the hood 2. On the other hand, when the hood 2 is lifted off, the existing connection is loosened, without additional handles being required from the outside. Since, as already stated above, all electrical devices are arranged in the hood, the water reservoir 1, the pump 8 can then and evaporative filter 5 can be cleaned very easily. It is therefore only necessary to remove the hood in order to separate the electrical devices, including the motor, from the other parts of the evaporative humidifier.

In Fig. 2 sind die Kupplung 30 sowie die benachbarten Teile der Pumpe und des Ventilators 21 vergrößert dargestellt. Wie aus Fig. 2 ersichtlich, sind die einander zugewandten Oberflächen der Kupplungshälften 31 und 32 im wesentlichen konisch ausgebildet, wobei im Zentrum noch ein Konus mit entgegengerichteter Steigung vorgesehen ist. Aufgrund der konischen Ausbildung der beiden Kupplungshälften 31 und 32 wird beim Aufsetzen der Haube 2 bzw. beim Kuppeln von Motor und Pumpe eine sichere Führung und Zentrierung erreicht. Die einander zugewandten Oberflächen der Kupplungshälften 31 und 32 können gegebenenfalls (nicht dargestellt) mit ineinander greifenden Zähnen versehen sein, um in allen Fällen, beispielsweise auch bei einem schwachen Magneten, eine sichere Drehmomentübertragung zu erhalten. Wie in Fig. 2 dargestellt, sei die Kupplungshälfte 32 als Permanentmagnet ausgebildet und in Richtung des Pfeiles 34 magnetisiert. Die Kupplungshälfte 31 kann auch Weicheisen oder aber auch aus einem Permanentmagneten, jedoch mit entgegengesetzter Magnetisierungseinrichtung bestehen. Die Kupplung 30 ist weiterhin derart bemessen, daß die Welle 12 bzw. das Pumpenrad 13 in die dargestellte Position angehoben ist und somit eine besondere Axiallagerung der Pumpe nicht erforderlich ist.2, the coupling 30 and the adjacent parts of the pump and the fan 21 are shown enlarged. As can be seen from FIG. 2, the surfaces of the coupling halves 31 and 32 facing one another are essentially conical, a cone with an opposite slope being provided in the center. Due to the conical design of the two coupling halves 31 and 32, when the hood 2 is put on, or when coupling the motor and pump, secure guidance and centering are achieved. The mutually facing surfaces of the coupling halves 31 and 32 can optionally (not shown) be provided with interlocking teeth in order to obtain reliable torque transmission in all cases, for example even with a weak magnet. As shown in Fig. 2, the coupling half 32 is designed as a permanent magnet and magnetized in the direction of arrow 34. The coupling half 31 can also consist of soft iron or of a permanent magnet, but with an opposite magnetization device. The clutch 30 is further dimensioned such that the shaft 12 or the pump wheel 13 is raised to the position shown and thus a special axial bearing of the pump is not required.

Damit bei abgehobener Haube 2 die Welle 12 nicht zu sehr aus der dargestellten zentrierten Position herausfällt, ist das Pumpengehäuse bzw. die Tragrohrhälften 9, 10 mit radial nach innen gerichteten Ansätzen 35, 36 versehen. In der dargestellten Position besteht ein schmaler Spalt zwischen der Welle 12 und den genannten Ansätzen 35, 36 und es erfolgt keine Berührung zwischen denselben.So that the shaft 12 does not fall out of the illustrated centered position too much when the hood 2 is lifted off, the pump housing or the support tube halves 9, 10 are provided with radially inwardly directed projections 35, 36. In the position shown, there is a narrow gap between the shaft 12 and the above-mentioned lugs 35, 36 and there is no contact between them.

Das Gehäuse der Pumpe 8 besteht, wie oben bereits angegeben, aus den beiden Tragrohrhälften 9, 10 und einem unteren topfförmigen Gehäuseteil 11, welches mittels einer Rastverbindung mit den Tragrohrhälften verbunden ist. Zum Reinigung der Pumpe wird das Gehäuseteil 11 nach unten abgezogen und die beiden Tragrohrhälften 9 und 10 können seitlich weggeschwenkt werden. Hierbei ist es wichtig, daß nach Abheben der Haube 2 zum Motor keine Verbindung mehr besteht und die Pumpe frei zugänglich ist.As already stated above, the housing of the pump 8 consists of the two support tube halves 9, 10 and a lower cup-shaped housing part 11, which is connected to the support tube halves by means of a snap-in connection. To clean the pump, the housing part 11 is pulled down and the two halves of the support tube 9 and 10 can be swung away to the side. It is important that after lifting the hood 2 there is no longer a connection to the engine and the pump is freely accessible.

Alternativ zu der oben erläuterten Magnetkupplung können auch andere Kupplungsarten eingesetzt werden. Genannt seien hier Steckkupplungen. Wichtig ist in allen Fällen jedoch, daß beim Abheben der Haube eine einwandfreie Trennung zwischen Motor und Pumpe ohne weiteres Zutun erfolgt und daß beim Aufsetzen der Haube auf den Wasservorratsbehälter 1 automatisch die geforderte Verbindung zwischen Motor und Pumpe hergestellt wird.As an alternative to the magnetic coupling explained above, other types of coupling can also be used. Plug-in couplings are mentioned here. It is important in all cases, however, that when the hood is lifted, the motor and pump are properly separated without further action and that the required connection between the motor and the pump is automatically established when the hood is placed on the water reservoir 1.
