Description

In Fig. 1 befindet sich in einem Behälter 1 ein Wasserbad 2, in dem ein T-förmiges Hohlrohr 3 rotiert. Der Antrieb erfolgt über einen Motor 4. Durch Öffnungen 5 und 6 am Hohlrohr 3 tritt Luft in das Rohr ein und entweicht durch die offenen Enden 7 und 8 der Querbalken des Hohlrohres in Richtung der Pfeile 9 und 10. Oberhalb des Wasserbades 2 wird eine durch die Pfeile 11 und 12 angedeutete Luftströmung erzeugt, durch welche die befeuchtete Luft abgeführt wird. In Fig. 1 is in a container 1, a water bath 2 in which a T-shaped hollow tube 3 rotates. The drive takes place via a Motor 4. Air enters the tube through openings 5 and 6 on the hollow tube 3 and escapes through the open ends 7 and 8 of the crossbar of the hollow tube in the direction of the arrows 9 and 10. Above the water bath 2 is indicated by the arrows 11 and 12 Air flow is generated through which the humidified air is removed.

In Fig. 2 ist eine andere Ausführungsform eines im Wasserbad bewegten Körpers dargestellt, nämlich ein einseitig abgewinkeltes Hohlrohr 13. Das Hohlrohr 13 kann wie das F i g. 1 um seine Längsachse rotieren oder in Pfeilrichtung 14 durch das Wasserbad geführt werden. Ob es sich dabei um eine geradlinige Bewegung oder um eine Bewegung entlang einer Kreis- oder Ellipsenbahn handelt, ist für den angestrebten Effekt belanglos, da die Luft infolge des am offenen Ende des Hohlrohres 13 im Wasserbad 2 auftretenden Unterdruckes entweichen kann. In Fig. 2 is another embodiment of a moving in a water bath Body shown, namely a hollow tube angled on one side 13. The hollow tube 13 can, like FIG. 1 rotate about its longitudinal axis or in the direction of arrow 14 through the water bath. Whether it is a straight line movement or is a movement along a circular or elliptical path, is aimed for Effect insignificant because the air as a result of the open end of the hollow tube 13 in the water bath 2 occurring negative pressure can escape.

F i g. 3 zeigt in Draufsicht einen rotierenden Körper 15, der gegenüber dem T-förmigen Hohlrohr3 nach F i g. 1 zwei weitere Querbalken 16 und 17 aufweist, durch die ebenfalls Luft in das Wasserbad eintreten kann. F i g. 3 shows in plan view a rotating body 15, the opposite the T-shaped hollow tube 3 according to FIG. 1 has two further crossbeams 16 and 17, through which air can also enter the water bath.

In Fig.4 ist ein einzelner Querbalken 18 dargestellt, dessen offenes Ende 19 auf der der Bewegungsrichtung 20 abgewandten Seite abgeschrägt ist. In Figure 4, a single crossbar 18 is shown, the open End 19 is beveled on the side facing away from the direction of movement 20.

F i g. 5 zeigt als weitere Variante einen Querbalken 21 mit U-förmigem Profil. Als Luftaustrittsöffnung ist ein Schlitz 22 vorgesehen. F i g. 5 shows, as a further variant, a transverse bar 21 with a U-shape Profile. A slot 22 is provided as the air outlet opening.

In F i g. 6 sind als Luftaustrittsöffnungen bei einem Querbalken 23 mit abgeflachtem Profil einzelne Luftlöcher 24 vorgesehen. Ein U-förmiges oder abgeflaches Profil der Querbalken bringt eine erhebliche Verringerung des Bewegungswiderstandes im Wasserbad mit sich, wodurch bei gleichem Verdunstungseffekt eine Verringerung der zur Bewegung erforderlichen Motorleistung erzielt wird. In Fig. 6 are used as air outlet openings in a crossbeam 23 individual air holes 24 are provided with a flattened profile. A U-shaped or The flattened profile of the crossbeams significantly reduces resistance to movement in the water bath, which results in a reduction with the same evaporation effect the motor power required for movement is achieved.

Claims

Claims: 1. Humidifier with an immersed in a water bath, moving body, d u r ch g e indicates that the body (3, 13, 16, 17, 18, 21, 23) has at least one air duct leading from the space outside the water bath in the water bath, and that the end or ends (7, 8, 19, 22, 24) of the or the air channels in the water bath are arranged so that by the movement of the body a negative pressure is created at the opening or openings through which air flows through the duct sucked in and conveyed into the water.

2. Humidifier according to claim 1, characterized in that a rotating body is provided.

3. Humidifier according to claim 2, characterized in that the or the ends of the air duct in the water bath at a distance from the axis of rotation of the rotating one Body are arranged.

4. Humidifier according to claim 3, characterized in that the rotating body has one or more transverse beams to its axis of rotation.

5. Humidifier according to claim 4, characterized in that the rotating body as a hollow tube with one or more crossbeams open at the ends is formed (F i g. 2, 3).

6. Humidifier according to claim 5, characterized in that the open ends of the crossbeams are beveled (Fig. 4).

7. Air humidifier according to one of claims 1 to 6, characterized in that that one or more openings or

Slots arranged on the opposite side of the direction of movement are (Fig. 5, 6).

8. Air humidifier according to one of claims 1 to 7, characterized by flattening the crossbeams (Fig. 5, 6).

The invention relates to an air humidifier with a water bath immersed moving body.

In the case of humidifiers, it is already known to increase the effect the humidification, which is usually between a water bath and the one above it located air occurs, a heating of the water bath and / or mechanically on Provide means to act on the water. For this purpose, so-called rotating baffle discs, on which water is atomized, pure atomizers or immersed in the water bath rotating body proposed.

If good air humidification is to be achieved, this results in these constructions a quite considerable size of the air humidifier, what with the use; innèrhålb closed spaces or as part of a device very can be disadvantageous.

Heating the water bath can also be disruptive be because it inevitably an increase in the temperature of the air above the water bath occurs.

The object of the invention is now to provide an air humidifier with increased To build moistening effect, so that once the size of the device is reduced and on the other hand, the heating of the water bath can be omitted.

The invention achieves this in that a moving in a water bath Body is provided which has at least one air duct leading from the room outside of the water bath in the water bath, and that the end or ends of the or the air channels in the water bath are arranged so that through the moving body a negative pressure is created at the opening or openings through which air flows through the duct sucked in and conveyed into the water.

This ensures that, in addition to the movement of the water bath, additional fine air bubbles from the ends of the air duct through the water bath to the water surface rise, not in calm, but in moving water. This makes one surprisingly high evaporation effect, as z. B.

as experiments have shown, through the pure outflow of air in the Water bath by means of an aeration stone, which is common in aquariums, is by no means is achieved. Even if the pump output is increased, such a Aeration of the water bath did not achieve these results.

There is a particularly advantageous embodiment of the invention in providing a rotating body in which the end or ends of the or the air ducts are arranged at a distance from the axis of rotation. In an advantageous manner one or more crossbars can be provided on the rotating body for this purpose.

It has proven to be particularly advantageous here when rotating Body to use a hollow tube with crossbeams open at the ends, which also are hollow and are beveled at the ends.

Instead of or in addition to the open ends, there is an advantageous one Possibility of making openings or slots on the one facing away from the direction of movement Side of the crossbeam to be provided.

To reduce the flow resistance of the rotating body and thereby save drive power without reducing the evaporation capacity, it has proven to be particularly beneficial to flatten the crossbeams or as Form U-shaped profile.

In the in the following and in the F i g. 1 to 6 closer The invention is explained in more detail in the illustrated embodiments. It shows F i g. 1 shows a basic structure of an exemplary embodiment of the invention a body rotating in a water bath, FIG. 2 a rotating body designed as a hollow tube Body, fig. 3 a rotating body with two or four transverse beams, FIG. 4 a Crossbeam with a bevel at its open end, Fig. 5 a crossbeam with a U-shaped profile and slotted air outlet opening, Fig. 6 a transverse bar with several additional holes as air outlet openings.
