- the suction and exhaust openings of the air duct are closed by porous and / or lattice-like disks, which contribute to a substantial noise insulation of airborne noise.
- the arrangement of the fan, the condenser and the compressor result in an orderly routing of the air sucked in by the fan, so that the greatest possible cooling of the unit parts is achieved with the lowest fan output and the lowest possible circulating air flow can be used.
- the panes closing the intake and exhaust openings should be selected in such a way that they offer as little resistance as possible with the greatest possible sound insulation of the air passing through.
- the panes can consist of mats made of textile material, possibly with metal mesh inserts. They are conveniently easily interchangeable so that they can be replaced quickly if their porosity should be reduced by clogging with dust and dirt.
- the suction and discharge openings are expediently located on a base side, and these are provided with closing doors on which the panes or mats are held.

- a device for measuring the overpressure is expediently provided in the air duct, which, when the overpressure rises, indicates that the air permeability of the mats has decreased to such an extent that they have to be replaced.
- a further sound reduction can be achieved in that the side walls of the air duct are lined with the air sound absorbing material, which is known in different forms.
- the electrical duct is also expedient in the air duct Control of the device, in particular the power part of the control, arranged so that they are cooled by the fan air flow.
- the air duct can consist of a U-shaped, tube-like tube. It can also be formed by a box which is provided with a separating web part to form two parallel branches, one side of the box being provided with the suction and exhaust openings.

- the compressor and / or the condenser can be connected to the wall of the air duct via elastic elements, so that these parts that generate vibrations and noise are additionally decoupled.
- the compressor and / or the condenser are expediently supported on the bottom of the air duct by elastic elements.
- the air duct is open at the top and is closed by the bottom of the body of the cooling container placed on the base part.
- the bottom area of the container body can be provided with a mat that seals the air duct.
- the cooling container housing is articulated to an upper side edge of the base box or frame.

Abstract
Description
Die Erfindung betrifft einen Kühl- und/oder Gefrierschrank mit einem Sockelteil, in dem der von einem Ventilator angeblasene Verflüssiger und der Kompressor untergebracht sind und der mit Ansaug- und Ausblasöffnungen versehen ist.The invention relates to a refrigerator and / or freezer with a base part in which the condenser blown by a fan and the compressor are accommodated and which is provided with suction and discharge openings.
Für viele Anwendungsfälle ist es zweckmäßig, den Verflüssiger nicht in der Rückwand des Kühl- und/oder Gefrierschrankes oder im Abstand hinter der Rückwand anzuordnen, da diese Bauweise nicht nur zu einer Verbreiterung führt, sondern zusätzlich auch eine Belüftung der Rückwand oder des mit der Rückwand verbundenen mattenförmigen Verflüssigers gewährleistet sein muß, um die erforderliche Luftzirkulation zur Abführung der Wärme von dem Verflüssiger sicherzustellen. Aus diesem Grunde werden bei Kühl- und/oder Gefrierschränken der eingangs angegebenen Art die vorzugsweise als Einbaugeräte oder Untertisch-Geräte ausgebildet sind, der Verflüssiger mit Ventilator und der Kompressor in einem Sockelteil untergebracht, auf den der Behälterteil aufgesetzt ist. Der in dem flachen, kastenförmigen Sockelteil untergebrachte Verflüssiger muß von einem Ventilator angeblasen werden, um die erforderliche Luftzirkulation zur Abführung der Wärme zu erzeugen. Bei bekannten Geräten ist der Ventilator zwar hinter einer durch eine Frontblende verkleidete Ansaugöffnung angeordnet und bläst unmittelbar den Verflüssiger an. Die verwirbelte Blasluft durchzieht dann aber den Innenraum des Sockelteils in ungeordneter Form und sucht sich ihren Weg zu der ebenfalls durch die Frontblende verkleideten Ausblasöffnung. Bei den bekannten Geräten wird damit die von dem Ventilator angesaugte Luft nicht in optimaler Weise zur Kühlung des Verflüssigers und des Kompressor sowie weiterer wärmeerzeugender Teile ausgenutzt. Ein weiterer Nachteil der bekannten Geräte besteht darin, daß der Kompressor und der Ventilator störende Geräusche erzeugen, die zusätzlich noch durch den Sockelteil und den aufgesetzten Behälter, die Resonanzkörper bilden, verstärkt werden können, so daß diese den gestiegenen Anforderungen an einen leisen Betrieb nicht genügen.For many applications, it is advisable not to place the condenser in the rear wall of the refrigerator and / or freezer or at a distance behind the rear wall, since this design not only leads to widening, but also ventilation of the rear wall or the one with the rear wall connected mat-shaped condenser must be ensured to ensure the necessary air circulation to dissipate the heat from the condenser. For this reason, in the case of refrigerators and / or freezers of the type specified at the beginning, which are preferably designed as built-in appliances or under-counter appliances, the condenser with fan and the compressor are accommodated in a base part on which the container part is placed. The condenser housed in the flat, box-shaped base part must be blown by a fan, to generate the necessary air circulation to dissipate the heat. In known devices, the fan is arranged behind a suction opening covered by a front panel and directly blows on the condenser. The swirled blown air then traverses the interior of the base part in an unordered form and seeks its way to the blow-out opening, which is also clad by the front panel. In the known devices, the air sucked in by the fan is therefore not optimally used for cooling the condenser and the compressor as well as other heat-generating parts. Another disadvantage of the known devices is that the compressor and the fan produce disturbing noises, which can additionally be amplified by the base part and the attached container, which form resonance bodies, so that they do not meet the increased requirements for quiet operation .
Aufgabe der Erfindung ist es daher, einen Kühl- und/oder Gefrierschrank der eingangs angegebenen Art zu schaffen, der sich bei wirksamer Abführung von Wärme von dem Verflüssiger und Kompressor durch einen leisen Betrieb auszeichnet.The object of the invention is therefore to provide a refrigerator and / or freezer of the type mentioned, which is characterized by quiet operation with effective removal of heat from the condenser and compressor.
Erfindungsgemäß wird diese Aufgabe bei einem Kühl- und/oder Gefrierschrank der gattungsgemäßen Art dadurch gelöst, daß der Ventilator, der Verflüssiger und der Kompressor in einem geschlossenen Luftkanal gehaltert sind, dessen Ansaug- und Ausblasöffnungen durch poröse und/oder gitterartige Scheiben geschlossen sind.According to the invention, this object is achieved in a refrigerator and / or freezer of the generic type in that the fan, the condenser and the compressor are held in a closed air duct, the suction and discharge openings of which are closed by porous and / or grid-like disks.
Bei dem erfindungsgemäßen Kühl- und/oder Gefrierschrank sind die geräuscherzeugenden Aggregatteile, nämlich der Ventilator und der Kompressor, gleichsam in dem ein geschlossenes Gehäuse bildenden Luftkanal gekapselt, so daß der Luftschall in dem Luftkanal eingefangen ist und nicht in beeinträchtigender Weise nach außen dringen kann. Die Ansaug- und Ausblasöffnungen des Luftkanals sind durch poröse und/oder gitterartige Scheiben geschlossen, die zu einer wesentlichen Geräuschdämmung des Luftschalls beitragen.In the refrigerator and / or freezer according to the invention, the noise-generating unit parts, namely the fan and the compressor, are, as it were, encapsulated in the air duct forming a closed housing, so that the airborne sound is trapped in the air duct and cannot penetrate to the outside in an impairing manner. The suction and exhaust openings of the air duct are closed by porous and / or lattice-like disks, which contribute to a substantial noise insulation of airborne noise.
Die Anordnung des Ventilators, des Verflüssigers und des Kompressors haben eine geordnete Führung der von dem Ventilator angesaugten Luft zur Folge, so daß mit geringster Ventilatorleistung die größtmögliche Kühlung der Aggregatteile erreicht wird und mit dem geringstmöglichen zirkulierenden Luftstrom gearbeitet werden kann. Die die Ansaug- und Ausblasöffnungen schließenden Scheiben sind derart auszuwählen, daß sie bei größtmöglicher Schalldämmung der durchtretenden Luft einen möglichst geringen Widerstand bieten. Die Scheiben können aus Matten aus textilem Material, eventuell mit Metall- Gitter- Einlagen bestehen. Sie sind zweckmäßigerweise leicht austauschbar gehaltert, so daß sie schnell ersetzt werden können, wenn ihre Porosität durch Verstopfen mit Staub und Schmutzteilen verringert sein sollte. Zweckmäßigerweise liegen die Ansaug- und Ausblasöffnungen auf einer Sockelseite, wobei diese verschließende Türen vorgesehen sind, an denen die Scheiben oder Matten gehaltert sind. Die Türen können einheitlich in die Frontblende eingegliedert werden, wobei auf ihrer Rückseite Halterungen, beispielsweise Führungen oder Klemmteile, für die Matten vorgesehen sind, die sich beim Schliessen der Türen an die Ränder der Ansaug- und Ausblasöffnungen anlegen.The arrangement of the fan, the condenser and the compressor result in an orderly routing of the air sucked in by the fan, so that the greatest possible cooling of the unit parts is achieved with the lowest fan output and the lowest possible circulating air flow can be used. The panes closing the intake and exhaust openings should be selected in such a way that they offer as little resistance as possible with the greatest possible sound insulation of the air passing through. The panes can consist of mats made of textile material, possibly with metal mesh inserts. They are conveniently easily interchangeable so that they can be replaced quickly if their porosity should be reduced by clogging with dust and dirt. The suction and discharge openings are expediently located on a base side, and these are provided with closing doors on which the panes or mats are held. The doors can be integrated uniformly into the front panel, with holders, for example guides or clamping parts, being provided on the back for the mats, which rest on the edges of the intake and exhaust openings when the doors are closed.
Zweckmäßigerweise ist in dem Luftkanal eine Einrichtung zur Messung des Überdruckes vorgesehen, die bei einem Ansteigen des Überdruckes anzeigt, daß die Luftdurchlässigkeit der Matten so weit abgesunken ist, daß diese ausgetauscht werden müssen.A device for measuring the overpressure is expediently provided in the air duct, which, when the overpressure rises, indicates that the air permeability of the mats has decreased to such an extent that they have to be replaced.
Eine weitere Schallverringerung kann dadurch erreicht werden, daß die seitlichen Wandungen des Luftkanals mit den Luftschall absorbierendem Material ausgekleidet werden, das in unterschiedlichen Formen bekannt ist.A further sound reduction can be achieved in that the side walls of the air duct are lined with the air sound absorbing material, which is known in different forms.
Zweckmäßigerweise ist in dem Luftkanal zusätzlich auch die elektrische Steuerung des Gerätes, insbesondere der Leistungsteil der Steuerung, angeordnet, so daß auch diese durch den Ventilatorluftstrom gekühlt werden.The electrical duct is also expedient in the air duct Control of the device, in particular the power part of the control, arranged so that they are cooled by the fan air flow.
Der Luftkanal kann aus einem U-förmig gebogenen gehäuseartigen Rohr bestehen. Er kann auch durch einen Kasten gebildet sein, der zur Bildung von zwei parallellen Zweigen mit einem trennenden Stegteil versehen ist, wobei eine Seite des Kastens mit den Ansaug- und Ausblasöffnungen versehen ist.The air duct can consist of a U-shaped, tube-like tube. It can also be formed by a box which is provided with a separating web part to form two parallel branches, one side of the box being provided with the suction and exhaust openings.
Der Verflüssiger besteht zweckmäßigerweise aus einteiligen, meanderförmig gebogenen Rohr, dessen kältester Teil dem Ventilator zugewandt ist. Die senkrecht von oben nach unten verlaufenden Rohrabschnitte des meanderförmig gebogenen Rohres können "Steg auf Lücke" stehen.The condenser expediently consists of a one-piece, meandering tube, the coldest part of which faces the fan. The pipe sections of the meandering bent pipe which run vertically from top to bottom can stand "web on gap".
Weiterhin kann die Lichtquelle für die Gerätebeleuchtung im Luftkanal angeordnet sein, wobei zu den zu beleuchtenden Teilen führende Lichtleiter vorgesehen sind, die aus Glasfasern oder Kunststoffleitungen bestehen können. Bei dieser Anordnung wird die wärmeerzeugende Lichtquelle ebenfalls durch den Ventilartorluftstrom gekühlt.Furthermore, the light source for the device lighting can be arranged in the air duct, light guides leading to the parts to be illuminated being provided, which can consist of glass fibers or plastic lines. With this arrangement, the heat-generating light source is also cooled by the valve air flow.
Geräusche entstehen nun nicht nur durch von den Aggregatteilen erzeugten Luftschall, sondern insbesondere auch durch Körperschall, der durch Resonanzkörper bildende Gehäuseteile zusätzlich verstärkt werden kann. Nach einer erfinderischen Weiterentwicklung ist daher vorgesehen, daß der Luftkanal den umgebenden Sockelkasten nicht berührt und an diesem durch elastische Elemente gehaltert ist. Diese elastischen Elemente können aus gedämpften Federelementen oder aus elastomeren Massen bzw. Körpern bestehen. Durch die Halterung des Luftkanals über elastische Elemente tritt eine Entkoppelung des Luftkanals mit den in diesem angeordneten Aggregatteilen von dem Sockelteil und dem Behälterteil ein, der eine Körperschall- Leitung wirksam unterbricht.Noises now arise not only from airborne noise generated by the unit parts, but in particular also from structure-borne noise, which can be additionally amplified by housing parts forming resonance bodies. According to an inventive further development, it is therefore provided that the air duct does not touch the surrounding base box and is held there by elastic elements. These elastic elements can consist of damped spring elements or of elastomeric masses or bodies. By holding the air duct via elastic elements, the air duct is decoupled from the base part and the container part with the aggregate parts arranged therein, which effectively interrupts a structure-borne sound line.
Zweckmäßigerweise ist der Luftkanal auf dem Boden des Sockelkastens durch elastische Elemente abgestützt.The air duct is expediently supported on the base of the base box by elastic elements.
Zusätzlich können der Kompressor und/oder der Verflüssiger über elastische Elemente mit der Wandung des Luftkanals verbunden sein, so daß diese Vibrationen und Geräusche erzeugenden Teile zusätzlich entkoppelt sind. Zweckmäßigerweise sind der Kompressor und/oder der Verflüssiger auf dem Boden des Luftkanals durch elastische Elemente abgestützt.In addition, the compressor and / or the condenser can be connected to the wall of the air duct via elastic elements, so that these parts that generate vibrations and noise are additionally decoupled. The compressor and / or the condenser are expediently supported on the bottom of the air duct by elastic elements.
In anderer Ausgestaltung der Erfindung kann vorgesehen sein, daß der Luftkanal nach oben hin offen ausgebildet und durch den Boden des auf den Sockelteil aufgesetzten Korpus des Kühlbehälters geschlossen ist. Dabei kann der Bodenbereich des Behälter- Korpus mit einer den Luftkanal abdichtenden Matte versehen sein.In another embodiment of the invention it can be provided that the air duct is open at the top and is closed by the bottom of the body of the cooling container placed on the base part. The bottom area of the container body can be provided with a mat that seals the air duct.
Nach einer weiteren Ausgestaltung ist vorgesehen, daß das Kühlbehältergehäuse mit einer oberen Seitenkante des Sockelkastens oder -Rahmens gelenkig verbunden ist. Diese Ausgestaltung ermöglicht einen schnellen und einfachen Zugang zu den in dem Sockelteil angeordneten Aggregatteilen zum Zwecke der Wartung und Reparatur. Um ein derartiges Abklappen des Kühlbehältergehäuses zu ermöglichen, werden die zu dem Verdampfer führenden Leitungen entsprechend lang und flexibel ausgebildet.According to a further embodiment it is provided that the cooling container housing is articulated to an upper side edge of the base box or frame. This configuration enables quick and easy access to the unit parts arranged in the base part for the purpose of maintenance and repair. In order to enable the cooling container housing to fold down in this way, the lines leading to the evaporator are designed to be correspondingly long and flexible.
Nach einer anderen Ausführungsform ist vorgesehen, daß der Sockelkasten mit dem in diesem gehalterten Luftkanal zwischen über den Boden des Kühlbehälters hinaus verlängerten Seitenwänden des Schrankes einschiebbar ist. Auch diese Ausgestaltung ermöglicht eine gute Zugänglichkeit zu den in dem Luftkanal- Gehäuse gekapselten Aggregatteilen. Um diese Ein- und Ausschiebbarkeit zu ermöglichen, müssen die Kältemittelleitungen entsprechend lang und flexibel ausgebildet sein.According to another embodiment, it is provided that the base box with the air duct held in it can be inserted between the side walls of the cabinet, which are extended beyond the bottom of the cooling container. This configuration also enables good accessibility to the unit parts encapsulated in the air duct housing. In order to enable this insertion and removal, the refrigerant lines must be long and flexible.
