Description

TECHNISCHER BEREICHTECHNICAL PART

Die Erfindung betrifft Kühleinrichtungen.The invention relates to cooling devices.

Die Erfindung betrifft besonders - jedoch nicht ausschließlich - multi-funktionale Einrichtungen zum Weiterleiten des Schmelzwassers und zur Beseitigung des Vakuums bei Eisschmelzsystemen von Kühlern.The invention particularly, but not exclusively, relates to multi-functional devices for passing the melt water and removing the vacuum in ice melting systems of coolers.

STAND DER TECHNIKSTATE OF THE ART

Bei Kühlern ohne Eisbildung (no-frost) wird die Vereisung am Evaporator durch Erwärmung mittels Resistenz beseitigt. Um das Eis, das zu Wasser umgewandelt wird, aus dem Kühler herauszuleiten, wird ein Entlastungsrohr benutzt. Während sich ein Ende des Entlastungsrohrs zum Evaporator öffnet, erstreckt sich das andere Ende zur Verdampfungskammer, welche sich auf einem Kompressor befindet, der am Boden hinter dem Kühlerkörper angebracht ist. Das Wasser, das in den Behälter läuft, verdampft durch die Hitze, die während des Betriebs des Kompressors entsteht, wodurch der Behälter dann geleert und somit Platz für erneuten Flüssigkeitseintritt erzeugt wird.In coolers without ice formation (no-frost) the icing on the evaporator is eliminated by heating by means of resistance. To discharge the ice, which is converted to water, out of the cooler, a relief tube is used. As one end of the relief tube opens to the evaporator, the other end extends to the vaporization chamber, which is on a compressor mounted at the bottom behind the radiator body. The water that runs into the container evaporates due to the heat generated during operation of the compressor, which then empties the container and thus creates room for re-entry of liquid.

Ein Grund der Vereisung am Evaporator ist, dass die Außenluft beim Öffnen der Kühlkammer hineindringt und mit dem Evaporator in Kontakt kommt. Eigentlich bildet der Entlastungsschlauch auch einen Kanal, wodurch die Außenluft den Evaporator erreichen kann. Um diesen Zustand aber zu verhindern, wird dem Leitungsrohr in Erstreckungsrichtung eine kurze U-Form gegeben und dadurch eine Wasserdichtung erzeugt. Somit bleibt ein Teil des geschmolzenen Wassers ständig im Schlauch und verhindert den Lufteindrang.One reason for the icing on the evaporator is that the outside air penetrates when opening the cooling chamber and comes into contact with the evaporator. Actually, the relief hose also forms a channel, whereby the outside air can reach the evaporator. However, in order to prevent this condition, the conduit is given a short U-shape in the direction of extent, thereby producing a water seal. Thus, a part of the molten water is constantly in the hose and prevents the Lufteindrang.

Eine weitere Folge des Eindrangs der Außenluft in den Kühler, insbesondere in die Kühlkammer, ist, dass ein Vakuum entsteht. Bei Geräten wie Kühlschrank bleibt die warme Außenluft nach dem Öffnen und Schließen des Deckels, z.B. in der Kühlkammer, gesperrt. Nach dem erneuten Kühleffekt des Kühlschranks lässt der Druck der gekühlten Warmluft nach und es entsteht ein Vakuum in der entsprechenden Kammer. Wenn der Benutzer den Deckel nochmals öffnen möchte, hat er die Kraft, die durch das Vakuum entsteht, zu bewältigen.Another consequence of the penetration of the outside air into the cooler, in particular into the cooling chamber, is that a vacuum is created. For appliances such as refrigerators, the warm remains Outside air after opening and closing the lid, eg in the cooling chamber, locked. After the cooling effect of the refrigerator again, the pressure of the cooled warm air decreases and a vacuum is created in the corresponding chamber. When the user wants to reopen the lid, he has to cope with the force created by the vacuum.

Um diesen Zustand zu verhindern, befindet sich auf dem Kühlerkörper eine Vakuum-Ablassöffnung, die sich nach außen öffnet. Das Vakuum-Ablassrohr, das an diese Öffnung angebracht wird, ist mit einem Einrichtungsventil versehen. Somit wird gewährleistet, dass Außenluft hineingenommen wird, nur wenn ein Vakuum entsteht, und die Öffnung zu ist, wenn kein Vakuum vorhanden ist.To prevent this condition, located on the radiator body, a vacuum discharge opening, which opens to the outside. The vacuum discharge pipe, which is attached to this opening, is provided with a Einrichtungsventil. Thus, it is ensured that outside air is taken in only when a vacuum is created and the opening is closed when there is no vacuum.

Anstatt das Vakuum und Defrostwasser über zwei verschiedene Schlauchsysteme zu übertragen, wurde ein multi-funktionales Entlastungssystem entwickelt, womit diese Aufgabe durch eine einzige Konstruktion gelöst werden konnte.Instead of transferring the vacuum and defrost water via two different hose systems, a multi-functional unloading system was developed, which solved this problem with a single design.

Eine Ausführung bezüglich dieser Einrichtung wird bei JP2005226964 beschrieben. Ein vertikaler Schlauch, an einem Ende befestigt zum Gefrierer und an dem anderen Ende befestigt zur Kühlkammer, öffnet sich zur Eintrittsmündung eines weiteren Schlauches, welcher an einem Ende mit dem Kühler und an dem anderen Ende mit dem Verdampfungsbehälter verbunden ist. Somit wird das Defrostwasser, das sich in der Gefrierkammer sammelt, zur Mündung der Kühlkammer des zweiten Schlauches gefördert und von dort aus in den Verdampfungsbehälter weitergeleitet.An embodiment relating to this device is included JP2005226964 described. A vertical hose attached to the freezer at one end and secured to the cooling chamber at the other end opens to the inlet of another hose which is connected at one end to the radiator and at the other end to the evaporation reservoir. Thus, the defrost water, which collects in the freezing chamber, promoted to the mouth of the cooling chamber of the second tube and forwarded from there into the evaporation tank.

Bei dieser Ausführung wird ein Vakuum, das in der Gefrierkammer entstehen kann, durch das Ende des ersten Schlauches, das sich zur Kühlkammer öffnet, verhindert. Weiters wird der Eindrang der Außenluft in die Kühlkammer bei diesem System durch ein Einrichtungsventil verhindert, welches an das Ende des zweiten Schlauches angebracht ist, das sich zur Verdampfungskammer öffnet.In this embodiment, a vacuum, which may arise in the freezing chamber, is prevented by the end of the first tube, which opens to the cooling chamber. Further, the intrusion of the outside air into the cooling chamber in this system is prevented by a device valve attached to the end of the second tube opening to the vaporization chamber.

Diese Wasserförderungseinrichtung beinhaltet zwar zur gleichen Zeit auch eine Vakuumbeseitigungsfunktion, ist aber besonders bei der Herstellung wegen der Montagezeit und den Herstellungskosten keinerlei vorteilhaft, da sie aus zwei Teilen besteht, und für den Übergang von dem ersten Schlauch zum zweiten Schlauch an dem Anschlusspunkt eine trichterförmige Gestaltung erfordert. Außerdem ist es absolut unpraktisch ein vielteiliges Einrichtungsventil einzusetzen.Although this water pumping device also includes a vacuum removal function at the same time, it is not particularly advantageous in manufacturing because of the assembly time and manufacturing cost because it consists of two parts and a funnel-shaped configuration for the transition from the first hose to the second hose at the connection point requires. In addition, it is absolutely impractical to use a multipart Einrichtungsventil.

Die Druckschrift US 5,557,942 beschäftigt sich nicht mit der Vakuumsbeseitigung, sondern vielmehr mit dem Druckausgleich zwischen dem Inneren eines Kältegerätes und der Atmosphäre. Ein Kühlgerät gemäss dass Oberbegriff von Ansprunch 1 ist aus US 5 557 942 bekannt.The publication US 5,557,942 is not concerned with the vacuum removal, but rather with the pressure equalization between the interior of a refrigerator and the atmosphere. A refrigerator according to the preamble of Ansprunch 1 is made US 5 557 942 known.

Die Druckschrift US 5,499,514 offenbart ein Abtauwasserableitungssystem mit einer Auffangschale.The publication US 5,499,514 discloses a defrost water drainage system with a drip tray.

Wie bei Figur-2 zu sehen, besteht der Anschlussschlauch (3) aus einem Vakuumentlastungsschlauch (3.1), der sich vertikal weiterzieht, einem Heberelement (3.2), das in Form von einem U-förmigen Rohr gestaltet und in einem bestimmten Winkel (a) geneigt positioniert ist, und einem Anschlusskanal (3.3) mit drei Löchern, welcher den Vakuumentlastungsschlauch (3.1) und das Heberelement (3.2) dem Entlastungsanschlussschlauch (3.4) anschließt, der sich dem Hauptentlastungsschlauch (4) öffnet.As seen in Figure-2, the connection hose (3) consists of a vacuum relief hose (3.1), which moves vertically, a lifting element (3.2) designed in the form of a U-shaped tube and at a certain angle (a) is positioned inclined, and a connection channel (3.3) with three holes, which the vacuum relief hose (3.1) and the lifting element (3.2) The discharge connection hose (3.4) connects, which opens to the main relief hose (4).

Der Anschlussschlauch (3) besteht aus einem L-Schlauch, dessen oberer Teil den kurzen Rand bildet. Am Ende des kurzen Randes befindet sich eine Eintrittsöffnung (3.1.1), welcher der Vakuumöffnung (2.1) angeschlossen wird. Die Eintrittsöffnung (3.1.1), die sich über einen Bogen (3.1.2) horizontal weiterzieht, öffnet sich in vertikale Position und erstreckt sich über ein Verlängerungsteil (3.1.3) bis zum Anschlusskanal (3.3) vertikal und linear weiter. Der Vakuumentlastungsschlauch (3.1) ist dem Anschlusskanal (3.3) an der Anschlussfahne (3.1.4) befestigt.The connection hose (3) consists of an L-hose whose upper part forms the short edge. At the end of the short edge there is an inlet opening (3.1.1), which is connected to the vacuum opening (2.1). The inlet opening (3.1.1), which continues horizontally via an arch (3.1.2), opens in a vertical position and extends vertically and linearly via an extension part (3.1.3) to the connection channel (3.3). The vacuum relief hose (3.1) is attached to the connection channel (3.3) on the connection lug (3.1.4).

Das Heberelement (3.2) besteht aus einem Schlauch, dessen Eintrittsöffnung (3.2.1) an die Defrostwasseröffnung (2.2) montiert wird, und ergänzt mit einem oberen Kanal (3.2.3), der sich über einen Bogen (3.1.2) der Bodenebene geneigt (a) weiterzieht und einem unteren Kanal (3.2.5), der über einem U-förmigen Umleitestück (3.2.4) dem oberen Kanal (3.2.3) parallel läuft, an der Austrittsöffnung (3.2.6) dem Anschlusskanal (3.3) angeschlossen wird.The lifting element (3.2) consists of a hose whose inlet (3.2.1) is mounted on the defrost water opening (2.2), and completed with an upper channel (3.2.3) extending over an arc (3.1.2) of the ground plane inclined (a) moves on and a lower channel (3.2.5) which runs parallel to the upper channel (3.2.3) via a U-shaped diverting piece (3.2.4), at the outlet opening (3.2.6) the connection channel (3.3 ) is connected.

Der Anschlusskanal (3.3) besteht aus einem U-förmigen Rohr, das dem Umleitestück auf der vertikalen Achse symmetrisch liegt. Doch dieses Rohr ist an der Wassereintrittsöffnung (3.3.2), welche das obere Ende bildet, über die Austrittsöffnung (3.2.6) an das Heberelement (3.2), und an der Austrittsöffnung (3.3.3), welche das untere Ende bildet, über einem geneigten Schlauch (3.4.1) an den Entlastungsanschlussschlauch (3.4) befestigt. Weiters ist das Rohr über eine kreisförmige Vakuumöffnung (3.3.1), die sich oberhalb des Anschlusskanals befindet (3.3), an der Anschlussfahne (3.1.4) an den Vakuumentlastungsschlauch befestigt.The connection channel (3.3) consists of a U-shaped tube which is symmetrical to the diverting piece on the vertical axis. But this pipe is at the water inlet opening (3.3.2), which forms the upper end, via the outlet opening (3.2.6) to the lifting element (3.2), and at the outlet opening (3.3.3), which forms the lower end, attached to the discharge connection hose (3.4) via an inclined hose (3.4.1). Furthermore, the pipe is attached to the vacuum relief hose via a circular vacuum opening (3.3.1), which is located above the connection channel (3.3), on the connection lug (3.1.4).

Der Entlastungsanschlussschlauch (3.4) ist mittels einem Bogen (3.4.2), welcher mit dem geneigten Schlauch (3.4.1) verbunden ist, mit dem vertikal linearen Entlastungsanschluss (3.4.3) an den Hauptentlastungsschlauch (4) befestigt.The discharge connection hose (3.4) is attached to the main discharge hose (4) by means of a bend (3.4.2) connected to the inclined hose (3.4.1) with the vertical linear discharge connection (3.4.3).

Die Gefrierkammer (2) löst bei Defrost mittels der Resistenz an dem Evaporator (2.3) die Vereisung, leitet das Defrostwasser, das dadurch entsteht, weiter, und wirft das Defrostwasser mit Hilfe der Anziehungskraft der Erde aus der Defrostwasseröffnung (2.2) heraus. Somit wird gewährleistet, dass das Wasser, welches aus der Eintrittsöffnung (3.2.1) kommt, durch den Bogen (3.2.2) läuft und durch den zur Bodenebene geneigten oberen Kanal (3.2.3) heraustritt. Das Defrostwasser, das durch das Umleitestück (3.2.4) der Bodenebene entgegengesetzt umgeleitet wird, läuft durch den unteren Kanal hoch und verlässt das Heberelement (3.2) aus der Austrittsöffnung (3.2.6). Somit läuft das Defrostwasser, das im Anschlusskanal erneut in Richtung Bodenebene gerichtet wird, durch den geneigten Schlauch (3.4.1) und wird mittels Bogen in vertikale Position gerichtet, und läuft von dort aus durch den Entlastungsanschluss (3.4.3) und den Hauptentlastungsschlauch (4) und fließt letztendlich in die Verdampfungskammer.The freezing chamber (2) dissolves the icing in defrost by means of the resistance at the evaporator (2.3), forwards the defrost water that results from it, and ejects the defrost water from the defrost water opening (2.2) with the help of the force of attraction of the earth. This ensures that the water coming out of the inlet opening (3.2.1) passes through the arch (3.2.2) and exits through the upper channel (3.2.3) inclined to the ground level. The defrost water, which is diverted by the diverting piece (3.2.4) opposite the ground level, rises through the lower channel and leaves the lifting element (3.2) from the outlet opening (3.2.6). Thus, the defrost water, which is directed in the connection channel again in the direction of ground level, through the inclined tube (3.4.1) and is directed by means of bow in a vertical position, and runs from there through the discharge port (3.4.3) and the main discharge hose ( 4) and ultimately flows into the vaporization chamber.

Nachdem der Durchlauf des Defrostwassers abbricht, bleibt ein Teil des Wassers wegen der Neigung des unteren Kanals (3.2.5) nach oben im unteren Kanal (3.2.5), im Umleitestück (3.2.4) und im oberen Kanal (3.2.3) zurück. Da kein Wasserdurchlauf mehr stattfindet wird auch keine Abhebung erzeugt.After the passage of the defrost water stops, part of the water stays upwards in the lower channel (3.2.5), in the diverting piece (3.2.4) and in the upper channel (3.2.3) because of the inclination of the lower channel (3.2.5). back. Since there is no water flow, no lift is generated.

Wenn ein Vakuum zustande kommt, wenn Außenluft in die Gefrierkammer (2) eindringt und schnell gekühlt wird, wird eine Absaugung aus der Vakuumöffnung (2.1) und der Defrostwasseröffnung (2.2) erzeugt. Aus der Defrostwasseröffnung, die durch die Wasserdichtung (3.2) gestopft wird, findet keine Absaugung statt. Doch der Vakuumentlastungsschlauch (3.1) fördert das Vakuum mittels der Anschlussfahne (3.1.4) in den Anschlusskanal (3.3). Dort wird das Vakuum beseitigt, indem über den geneigten Schlauch (3.4.1) und den Hauptentlastungsschlauch Außenluft hineingesaugt wird. Da die Vakuumöffnung (2.1) von dem Evaporator weit entfernt ist, kommt wegen der gesaugten Außenluft keine Vereisung an dem Evaporator zustande.When a vacuum is established, when outside air enters the freezing chamber (2) and is cooled rapidly, a suction is produced from the vacuum opening (2.1) and the defrost water opening (2.2). From the Defrostwasseröffnung, which is stuffed by the water seal (3.2), no extraction takes place. But the vacuum relief hose (3.1) conveys the vacuum by means of the connection lug (3.1.4) into the connection channel (3.3). The vacuum is removed there by sucking in outside air via the inclined hose (3.4.1) and the main relief hose. Since the vacuum opening (2.1) is far away from the evaporator, there is no icing on the evaporator due to the sucked outside air.

Auch bei Kühlschränken (1), bei denen sich die Kühlkammer (2) am Boden befindet, kann dieses System angewandt werden. Da der Evaporator (2.3) sich bei diesen Kühlschränken oben befindet, ist es möglich, das Verlängerungsstück (3.1.3) der Vakuumöffnung (2.1) abzukürzen und die Eintrittsöffnung (3.2.1) des Heberelements (3.2) mit einem ähnlichen Verlängerungsstück hochzunehmen. Da der Wassereintritt (3.3.2) mit Neigung (α) zur Bodenebene verwirklicht wird, ist der Anschlussschlauch (3), der wegen den Bögen (3.2.2, 3.4.2) Wellen bildet, so konstruiert, dass sich die Eintritts- (3.2.1) und Entlastungsöffnungen (3.4.3) auf der vertikalen Achse kreuzen und somit von der Anziehungskraft der Erde mehr profitiert wird. Außerdem wird durch die Höhe des Verlängerungsstücks (3.1.3) verhindert, dass das Defrostwasser bei einem Vakuum zur Kühlkammer (2) hochläuft.Even with refrigerators (1), where the cooling chamber (2) is located on the ground, this system can be used. Since the evaporator (2.3) is in these refrigerators At the top, it is possible to shorten the extension piece (3.1.3) of the vacuum opening (2.1) and to lift up the inlet opening (3.2.1) of the lifting element (3.2) with a similar extension piece. Since the water inlet (3.3.2) with inclination (α) is realized to the ground level, the connecting hose (3), which because of the arcs (3.2.2, 3.4.2) waves, is designed so that the entry ( 3.2.1) and intersecting relief holes (3.4.3) on the vertical axis, thus benefiting more from the Earth's gravitational pull. In addition, the height of the extension piece (3.1.3) prevents the defrost water from running up to the cooling chamber (2) at a vacuum.

Denn es ist offensichtlich, dass ein Experte in der Technik anhand der obigen Beschreibungen ähnliche Konstruktionen entwickeln kann.Retention rights of this invention are described in the following claims, but can not be limited to the examples described in detail herein.
