Figur 2:
Eine Schnittdarstellung der erfindungsgemäßen Vorrichtung zum Verdunsten von Wasser von vorne.
Here show:
Figure 1:
A sectional side view of the device according to the invention for evaporating water.
Figure 2:
A sectional view of the device according to the invention for evaporating water from the front.

Eine wie in den Figuren 1 und 2 dargestellte, im wesentlichen horizontal angeordnete, tunnelförmige Außenwandung 1 umschließt einen Lüfter oder Ventilator, der aus einem Lüftermotor 2 sowie dem Lüfterflügel 3 besteht. Über den ihn umgebenden Lufteinlaufring 4 strömt die in die tunnelförmige Außenwandung 1 eintretende Luft, wobei ein Teilstrom der Luft über eine Auffangwanne 5 und der restliche Luftstrom über eine oder mehrere Verdunsterschalen 8 geführt wird.An essentially horizontally arranged, as shown in FIGS. 1 and 2, tunnel-shaped outer wall 1 encloses a fan or fan, which consists of a Fan motor 2 and the fan blade 3 exists. Over the surrounding air intake ring 4 flows the air entering the tunnel-shaped outer wall 1, whereby a Partial flow of air through a sump 5 and the rest of the air flow through one or several evaporator trays 8 is guided.

In den Figuren 1 und 2 sind jeweils sechs Verdunsterschalen 8 dargestellt, wobei diese - entsprechend einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung zum Verdunsten von Wasser - jeweils um 180° gegeneinander verdreht angeordnet sind. Mittels dieser Ausgestaltung wird eine Vervielfältigung der Verdunsterfläche erreicht. Durch einen seitlichen Versatz der Verdunsterschalen 8 kann zudem die Lufteinströmfläche vergrößert werden.In Figures 1 and 2, six evaporator trays 8 are shown, these - According to an advantageous embodiment of the device according to the invention for the evaporation of water - each rotated by 180 ° are. This configuration enables the evaporation surface to be reproduced reached. Through a lateral offset of the evaporator shells 8, the Air inflow area can be increased.

Bei der in der Figur 1 dargestellten Ausgestaltung der erfindungsgemäßen Vorrichtung zum Verdunsten von Wasser strömt Luft über den Lüfter 3 in die tunnelförmige Außenwandung 1. Es ist jedoch auch denkbar, daß der Lüfter 3 nicht an derjenigen Seite der tunnelförmigen Außenwandung 1, über die die Luft in die Außenwandung 1 eintritt, sondern an der entgegengesetzten Seite angeordnet ist.In the embodiment of the device according to the invention shown in FIG. 1 to evaporate water, air flows through the fan 3 into the tunnel-shaped outer wall 1. However, it is also conceivable that the fan 3 is not on that side of the tunnel-shaped outer wall 1, through which the air enters the outer wall 1, but is arranged on the opposite side.

Über wenigstens ein Tauwassereinleitungsrohr 9 gelangt das im Kühlmöbel anfallende Tauwasser in die Auffangwanne 5. Diese Auffangwanne ist mit Mitteln zum Erwärmen versehen, die - wie in den Figuren 1 und 2 dargestellt - beispielsweise als eine bodenseitig an der Auffangwanne 5 befestigte Heizung ausgebildet sein können. Hierbei ist die Heizung beispielsweise in Form einer mäanderförmig angeordneten Leitung 6, durch die ein heißes Medium - vorzugsweise ein heißes Gas - strömt, ausgebildet. Es ist deshalb zweckmäßig, wenn die Auffangwanne 5 aus einem gut wärmeleitenden Material besteht. Die Befestigung der Leitung 6 an dem Unterboden der Auffangwanne 5 kann beispielsweise mittels Metallschellen erfolgen; zudem ist die Verwendung einer Wärmeleitpaste denkbar und sinnvoll.About at least one condensation water inlet pipe 9 that is obtained in the refrigeration cabinet Defrost in the drip pan 5. This drip pan is with means for heating provided, which - as shown in Figures 1 and 2 - for example as a bottom attached to the sump 5 heater can be formed. Here is the heating, for example in the form of a meandering line 6, through which a hot medium - preferably a hot gas - flows. It is therefore useful if the sump 5 from a good heat-conducting Material exists. The attachment of line 6 to the bottom of the sump 5 can be done for example by means of metal clamps; in addition, the use of a Thermal paste is conceivable and useful.

Nicht verdunstetes Tauwasser aus der Auffangwanne 5 fließt über den Überlauf 10 in die unterhalb der Auffangwanne 5 angeordnete(n) Verdunsterschale(n) 8.Non-evaporated condensation water from the collecting trough 5 flows in via the overflow 10 the evaporator dish (s) 8 arranged below the collecting trough 5.

Die erfindungsgemäße Vorrichtung zum Verdunsten von Wasser weiterbildend wird vorgeschlagen, daß im Bereich der Auffangwanne 5 wenigstens ein Verdunsterschwammtuch 7 angeordnet ist. Dieses ist vorzugsweise - wie aus der Figur 2 ersichtlich - gewellt angeordnet.The device according to the invention for evaporation of water will be further developed proposed that at least one evaporator sponge cloth in the area of the collecting trough 5 7 is arranged. This is preferably - as in FIG. 2 visible - arranged wavy.

Des weiteren ist die Austrittsöffnung des bereits erwähnten Tauwassereinleitungsrohres 9 vorzugsweise im Bereich des Verdunsterschwammtuches 7 angeordnet. Mittels dieser Ausgestaltung der erfindungsgemäßen Vorrichtung zum Verdunsten von Wasser wird sichergestellt, daß das Verdunsterschwammtuch 7 nicht austrocknet, was zu einer Verschlechterung des Wirkungsgrades führen würde.Furthermore, the outlet opening of the condensation water introduction pipe already mentioned 9 is preferably arranged in the area of the evaporator sponge cloth 7. through this embodiment of the device according to the invention for evaporation of Water ensures that the evaporator sponge 7 does not dry out what would lead to a deterioration in efficiency.

Eine weitere vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung zum Verdunsten von Wasser ist dadurch gekennzeichnet, daß die Verdunsterschalen 8 einen Überlauf 11 aufweisen. Über diesen gelangt nicht verdunstetes Tauwasser in die jeweils darunterliegende Verdunsterschale 8.A further advantageous embodiment of the device according to the invention for Evaporation of water is characterized in that the evaporator trays 8 have an overflow 11. This does not allow evaporated condensation to get into the evaporator tray 8 underneath.

Vorzugsweise ist der Überlauf 11 der Verdunsterschale 8 niedriger als der jeweilige Verdunsterschalenrand 12 ausgebildet. Hierbei ist es zweckmäßig, wenn die Überläufe 11 in Form eines Schlauchstutzens ausgebildet sind; dadurch kann verhindert werden, daß Tauwasser am Boden entlang läuft. Ferner bietet diese Ausgestaltung die Möglichkeit, den untersten Überlauf 11 an eine aus dem Möbel entnehmbare, manuell zu entleerende Schale anzuschließen. Diese Option kann sich in Fällen extrem hohen Tauwasseranfalles, wie er beispielsweise an sehr heißen Tagen möglich sein kann, als zweckmäßig erweisen.The overflow 11 of the evaporator shell 8 is preferably lower than the respective one Evaporator shell edge 12 formed. It is useful if the overflows 11 are designed in the form of a hose connector; this can prevent that condensation runs along the floor. Furthermore, this configuration offers the possibility of the bottom overflow 11 to a removable from the furniture, manually to connect the emptying bowl. This option can become extremely high in cases Condensation, such as may be possible on very hot days, as prove appropriate.
