Die Erfindung betrifft ein Kühl- oder Gefriergerät, insbesondere für den Haushalt, mit einer eingebauten Wärmepumpe, deren Verdampfer einem zu kühlenden Abteil zugeordnet ist, deren Kondensator gekühlt ist und die einen motorgetriebenen Kompressor umfaßt.The invention relates to a refrigerator or freezer, in particular for the household, with a built-in heat pump, the evaporator of which is assigned to a compartment to be cooled, the condenser of which is cooled and which comprises a motor-driven compressor.
Es ist bei Kühl- oder Gefriergeräten dieser Art ganz allgemein bekannt, den Kondensator und den gekapselten Motorkompressor durch die Umgebungsluft zu kühlen. Um dabei eine ausreichende Wärmeabfuhr insbesondere am Kondensator zu erreichen, muß seine Temperatur erfahrungsgemäß etwa 500C bis 600C erreichen. Damit bei diesen Temperaturen noch eine Kondensation des Kältemittels eintritt, muß der Kompressor das Kältemittel auf einen entsprechend hohen Druck komprimieren. Daraus folgt aber nicht nur eine hohe mechanische Belastung für den eigentlichen Kompressor, sondern auch für den damit gekapselten Elektromotor. Außerdem geht die abgegebene Wärme an sich ungenutzt in den Aufstellungsraum des Kühl- oder Gefriergerätes über, wobei diese Wärme besonders in Vorratsräumen unerwünscht ist.It is generally known in refrigerators or freezers of this type to cool the condenser and the encapsulated motor compressor by means of the ambient air. In order to achieve adequate heat dissipation, especially at the condenser, experience has shown that its temperature must reach approximately 50 ° C. to 60 ° C. So that condensation of the refrigerant still occurs at these temperatures, the compressor must compress the refrigerant to a correspondingly high pressure. This not only results in a high mechanical load on the actual compressor, but also on the electric motor encapsulated with it. In addition, the heat given off goes unused into the room in which the refrigerator or freezer is installed, this heat being particularly undesirable in storage rooms.
Aufgabe der Erfindung ist es, ein Kühl- oder Gefriergerät der eingangs genannten Art zu schaffen, bei dem die von der Wärmepumpe insgesamt erzeugte Wärme in einfacher Weise zur Brauchwasserbereitung ausgenutzt werden kann.The object of the invention is to provide a refrigerator or freezer of the type mentioned, in which the from Heat pump total heat generated can be used in a simple manner for domestic hot water preparation.

Die Lösung dieser Aufgabe besteht gemäß der Erfindung darin, daß der Kondensator in Wärmeaustausch mit dem unteren Teil eines Brauchwasserkessels steht und der Kompressor mit einer Wärmedämmschicht versehen ist.The solution to this problem is, according to the invention, that the condenser is in heat exchange with the lower part of a domestic water boiler and the compressor is provided with a thermal insulation layer.
Bei dieser Ausgestaltung liegt der Kondensator der Wärmepumpe stets in relativ kühlem Wasser des Brauchwasserkessels, nachdem sich das erwärmte Wasser jeweils im oberen Abschnitt sammelt und der Kaltwasserzulauf ebenfalls in den unteren Teil des Brauchwasserkessels gelegt ist. Nachdem in einem Haushalt aufgrund von statistischen Untersuchungen der Bedarf an Energie zur Warmwasserbereitung um etwa 50% über dem des Bedarfs für die Kühlung liegt, ist somit im allgemeinen -eine bei etwa 300C bis 400C liegende Temperatur im unteren Teil des Brauchwasserkessels gegeben. Durch diese Verminderung der maximalen Kondensationstemperatur wird auch der Kompressionsdruck und demzufolge die mechanische Belastung des Kompressors und der elektrische Leistungsbedarf des Antriebsmotors entsprechend verringert. Aus diesem Grunde kann der gekapselte Motorkompressor mit einer Wärmeisolierschicht versehen werden, wobei die am Kompressor und am Motor noch entstehende restliche Wärmemenge durch die Sauggaskühlung vom Kältemittel aufgenommen wird. Eine erhöhte thermische Belastung des Motorkompressors tritt damit nicht ein und die dort erzeugte Wärme wird ohne sonstige Hilfseinrichtungen über das Kältemittel unmittelbar dem Brauchwasser zugeführt.In this embodiment, the condenser of the heat pump is always in the relatively cool water of the domestic water boiler, after the heated water collects in the upper section and the cold water inlet is also placed in the lower part of the domestic water boiler. Since the need for energy for hot water generation in a household is about 50% higher than the need for cooling based on statistical studies, there is thus generally a temperature of about 30 ° C. to 40 ° C. in the lower part of the domestic water boiler . As a result of this reduction in the maximum condensation temperature, the compression pressure and consequently the mechanical load on the compressor and the electrical power requirement of the drive motor are correspondingly reduced. For this reason, the encapsulated motor compressor can be provided with a heat insulating layer, with the remaining amount of heat still generated on the compressor and on the motor being absorbed by the refrigerant through the suction gas cooling. There is therefore no increased thermal load on the motor compressor and the heat generated there is fed directly to the domestic water via the refrigerant without any other auxiliary equipment.
Die Wärmeisolierschicht umschließt den Motorkompressor vorzugsweise allseitig, wobei die Wärmeisolierschicht noch schalldämpfende Eigenschaften aufweisen soll, um Betriebsgeräusche zu vermindern. Hierzu eignet sich insbesondere ge-The thermal insulation layer preferably encloses the motor compressor on all sides, with the thermal insulation layer still Should have sound-absorbing properties in order to reduce operating noise. Particularly suitable for this is

schäumter Kunststoff, wie er auch für die Wärmeisolierung von Kühlgerätewänden verwendet wird.foamed plastic, as it is also used for thermal insulation used by cooling unit walls.
Die Erfindung ist nachfolgend anhand der Zeichnung eines als Ausführungsbeispiel im Schnitt dargestellten Kühlschrankes näher erläutert.The invention is described below with reference to the drawing of a refrigerator shown in section as an exemplary embodiment explained in more detail.
Bei einem Kühlschrank 1 mit wärmeisolierten Wänden 2 ist unterhalb einer Gehäusestufe 3 ein Kompressor 4 einer Wärmepumpe angeordnet. Der sauggasgekühlte Kompressor 4 ist mit einem elektrischen Antriebsmotor in einer gemeinsamen Kapsel angeordnet und allseitig von einer Wärmeisolierschicht 5 umgeben. Der Kompressor 4 kann aber auch in einer wärmeisolierten, z.B. einstückig mit den Wänden 2 verbundenen Kammer des Gerätegehäuses untergebracht sein. Vom Kompressor 4 führt eine Rohrleitung zu einem Kondensator 6, der im unteren Teil eines ebenfalls wärmeisolierten, an der Rückseite des Gerätegehäuses angeordneten Brauchwasserkessels 7 liegt. Nach dem Kondensator 6 folgt ein im zu kühlenden Raum 8 vorgesehener Verdampfer 9, von dem eine Rohrleitung zurück zum Kompressor 4 führt.In the case of a refrigerator 1 with heat-insulated walls 2, a compressor 4 of a heat pump is below a housing stage 3 arranged. The suction gas-cooled compressor 4 is in a common capsule with an electric drive motor arranged and surrounded on all sides by a heat insulating layer 5. The compressor 4 can also be in a thermally insulated, For example, the chamber of the device housing connected in one piece with the walls 2 can be accommodated. From the compressor 4 leads a pipe to a condenser 6, which is in the lower part of a likewise heat-insulated, on the back of the device housing arranged domestic water boiler 7 is located. After the condenser 6, there follows a space 8 to be cooled Evaporator 9, from which a pipe leads back to the compressor 4.
Zur Erzielung einer guten Temperaturschichtung erstreckt sich der Brauchwasserkessel 7 annähernd über die gesamte Höhe des Gerätegehäuses. Auch der Wasserzulaufstutzen 10 mündet im Bereich des Kondensators 6 in den Brauchwasserkessel 7, so daß dort die geringste Kondensationstemperatur mit den günstigen Rückwirkungen auf den Motorkompressor 4 ausgenutzt werden kann. Als Material für die Wärmeisolierschicht ist geschäumter Kunststoff geeignet, der gleichzeitig gute schalldämpfende Eigenschaften besitzt.In order to achieve a good temperature stratification, the domestic water boiler 7 extends almost over the entire height of the device housing. The water inlet nozzle 10 also opens into the Area of the condenser 6 in the domestic water boiler 7, so that there the lowest condensation temperature with the favorable Effects on the motor compressor 4 can be exploited. Foamed plastic is used as the material for the thermal insulation layer suitable, which at the same time has good sound-absorbing properties.
