Description

Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, das zum Steuern des Kältemittelflusses wenigstens ein Magnetventil verwendet. Ein solches Magnetventil kann in einem Einkreis-Kältegerät dazu dienen, in einer The present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, which uses at least one solenoid valve to control the refrigerant flow.

Solenoid valves are used in a two-or multi-circuit device to selectively supply refrigerant to one of several evaporators.
Die Montage eines Magnetventils in einem Kältegerät ist mühsam, da nicht nur der Ventilkörper mechanisch fixiert werden muss, sondern Rohranschlüsse verlötet und elektrische Anschlüsse kontaktiert werden müssen. Herkömmlicherweise weisen The installation of a solenoid valve in a refrigerator is cumbersome because not only the valve body must be mechanically fixed, but soldered pipe connections and electrical connections must be contacted.

Magnetventilen in Haushaltskältegeräten teuer. Es besteht daher der Bedarf nach Lösungen, die den Aufwand beim Einbau der Magnetventile verringern.  Solenoid valves in household refrigerators expensive. There is therefore a need for solutions that reduce the effort when installing the solenoid valves.
Aufgabe der Erfindung ist, diesen Bedarf zu befriedigen. The object of the invention is to meet this need.
Die Aufgabe wird gelöst, indem bei einem Kältegerät mit wenigstens einem ersten Magnetventil, das an einem Gehäuse des Kältegeräts befestigt und mit elektrischen Anschlüssen des Gehäuses über ein erstes Kabel verbunden ist, eine Schale das Magnetventil und das Kabel überdeckt. Da die Schale das Kabel vor unvorhergesehener Beanspruchung schützt, ist eine Zugentlastung nicht mehr erforderlich, und die damit herkömmlicherweise verbundenen Kosten fallen fort. Zur Vereinfachung des Einbaus trägt bei, wenn das Kabel einen ersten Steckverbinder trägt und ein zu dem ersten Steckverbinder komplementärer Steckverbinder an dem Gehäuse vorgesehen ist. The object is achieved by covering a shell of the magnetic valve and the cable in a refrigeration device with at least a first solenoid valve which is attached to a housing of the refrigerator and is connected to electrical terminals of the housing via a first cable. Since the shell protects the cable from unforeseen stress, strain relief is no longer required and the cost traditionally associated with it is lost. For ease of installation, when the cable carries a first connector and a connector complementary to the first connector is provided on the housing.
Wenn der erste Steckverbinder, die Schale und das Magnetventil zu einer Baugruppe verbunden sind, können die nötigen elektrischen Kontakte des Kabels zum If the first connector, the shell and the solenoid valve are connected to an assembly, the necessary electrical contacts of the cable to the
Steckverbinder und zum Magnetventil außerhalb des Kältegerätegehäuses hergestellt werden, was den Einbauvorgang weiter vereinfacht.  Connector and the solenoid valve outside the refrigerator housing are made, which further simplifies the installation process.
Die Schale weist hierfür vorzugsweise wenigstens einen elastischen Rasthaken auf, der an dem Magnetventil angreift. So genügt es für die Verankerung des Magnetventils, es in den dafür vorgesehenen Einbauplatz in der Schale hineinzudrücken. Der For this purpose, the shell preferably has at least one elastic latching hook, which acts on the solenoid valve. So it is sufficient for the anchoring of the solenoid valve to push it into the designated slot in the shell. Of the
herkömmlicherweise mit dem Festschrauben des Magnetventils verbundene Aufwand entfällt. Da die Schale ein relativ kleinformatiges Teil ist und aus Kunststoff preiswert hergestellt werden kann, ist es bei ihr mit relativ geringem Aufwand möglich, ihre Form so an die des Magnetventils anzupassen, dass eine sichere Verrastung möglich ist. conventionally associated with the tightening of the solenoid valve effort is eliminated. Since the shell is a relatively small-sized part and can be made inexpensively from plastic, it is possible with relatively little effort to adapt their shape to that of the solenoid valve that a secure locking is possible.
Das Kabel kann zweckmäßigerweise zwischen dem ersten Steckverbinder und dem Magnetventil an wenigstens einer Stelle der Schale fixiert sein, um sicherzustellen, dass es nach dem Einfügen vom Magnetventil und Schale in das Kältegerät von der Schale vollständig abgedeckt und so vor Berührung geschützt ist. The cable may conveniently be fixed between the first connector and the solenoid valve at least at one point of the shell to ensure that it is completely covered by the shell after insertion from the solenoid valve and shell into the refrigerator and thus protected from contact.
Wenn ein Kältegerät mehrere Magnetventile aufweist, kann ein zweites solches If a refrigerator has a plurality of solenoid valves, a second such
Magnetventil zweckmäßigerweise von derselben Schale überdeckt sein. Insbesondere kann es zweckmäßigerweise Teil derselben Baugruppe sein wie die Schale und das erste Magnetventil. Solenoid valve be suitably covered by the same shell. In particular, it may conveniently be part of the same assembly as the shell and the first solenoid valve.
Grundsätzlich ist es denkbar, für jedes Magnetventil einen komplementären In principle, it is conceivable for each solenoid valve a complementary
Steckverbinder am Gehäuse vorzusehen. Wenn jedoch diese beiden Steckverbinder mit zwei ersten Steckverbindern der Schale kontaktiert werden müssen, können Provide connector on the housing. However, if these two connectors must be contacted with two first connectors of the shell, can
Fertigungstoleranzen zu Problemen führen. Deswegen ist das zweite Magnetventil vorzugweise mit dem ersten Steckverbinder über ein zweites Kabel verbunden. Diese Kabel sind vorzugweise am ersten Steckverbinder vormontiert, und werden erst beim Zusammenbau des Kältegeräts oder der darin zu montierenden Baugruppe mit den Magnetventilen steckverbunden. Manufacturing tolerances lead to problems. Therefore, the second solenoid valve is preferably connected to the first connector via a second cable. These cables are preferably preassembled on the first connector, and are only plugged into the assembly of the refrigerator or the assembly to be mounted therein with the solenoid valves.
Um Fehler beim Verbinden der Kabel mit den Magnetventilen auszuschließen, kann das erste Kabel kürzer sein als der kürzeste Weg zwischen dem ersten Steckverbinder und dem zweiten Magnetventil. Zwar kann das zweite Kabel dann zunächst fehlerhaft am ersten Magnetventil montiert werden, doch fällt dieser Fehler spätestens dann auf, wenn eine Kontaktierung des zweiten Magnetventils unmöglich ist. Die Schale weist vorzugweise wenigstens eine Rastkontur auf, die durch Aufstecken in Steckrichtung des Steckverbinders an dem Gehäuse des Kältegeräts verrastbar ist. Somit genügt ein einziger Handgriff, um die Steckverbinder miteinander zu kontaktieren und gleichzeitig die Schale am Gehäuse zu befestigen. Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgendenIn order to eliminate errors in connecting the cables to the solenoid valves, the first cable may be shorter than the shortest path between the first connector and the second solenoid valve. Although the second cable can then first be incorrectly mounted on the first solenoid valve, but this error falls at the latest when a contacting of the second solenoid valve is impossible. The shell preferably has at least one latching contour, which can be latched by plugging in the insertion direction of the connector to the housing of the refrigerator. Thus, a single handle is sufficient to contact the connectors with each other and at the same time to attach the shell to the housing. Further features and advantages of the invention will become apparent from the following

The compressor 6 feeds compressed refrigerant a condenser 7, which is here shown plate-shaped and mounted on the rear wall of the body 2 above the engine room 5, but could find space in a more compact design in the engine room 5 itself. At an outlet of the condenser 6, a solenoid valve assembly 8 is connected, the construction and mounting in

In the example shown in Fig. 1, the solenoid valve assembly is in one of a side wall and the ceiling of the

Engine room 5 limited corner mounted (and therefore largely obscured), but it is understood that in principle any solid surface of the engine room 5 and in particular a rear wall 9 thereof for the assembly of the solenoid valve assembly 8 comes into question.
Fig. 2 zeigt die Magnetventilbaugruppe 8 in einer vergrößerten perspektivischen Ansicht. Sie umfasst eine aus Kunststoff einteilig spritzgeformte Schale 10, die in ihrem Innern Steckplätze für zwei Magnetventile 1 1 , 12 aufweist. Die Magnetventile 1 1 , 12 haben hier ein im Wesentlichen quaderförmigen Körper, und an zwei einander gegenüberliegenden Wänden 13, 14 der Schale 10 sind jeweils elastisch auslenkbare Zungen 15 freigeschnitten, die ins Innere der Schale hineinragende Rasthaken 16 tragen. DieFig. 2 shows the solenoid valve assembly 8 in an enlarged perspective view. It comprises a molded plastic one-piece shell 10, which has slots for two solenoid valves 1 1, 12 in its interior. The solenoid valves 1 1, 12 here have a substantially cuboidal body, and on two opposite walls 13, 14 of the shell 10 are each elastically deflectable tongues 15th cut free, carry the locking hooks 16 projecting into the interior of the shell. The
Rasthaken 16 haben abgeschrägte Stirnflächen, die beim Eindrücken der Magnetventile 1 1 , 12 in ihre Steckplätze zunächst elastisch ausgelenkt werden, um anschließend eine Kante des Körpers der Magnetventile 12, 13 zu umgreifen und so die Magnetventile 12, 13 formschlüssig in der Schale 10 zu fixieren. Weitere ins Innere der Schale 10 hinein vorspringende Rasthaken 17 dienen der Sicherung von Rohranschlüssen 18 der Latch hooks 16 have beveled end surfaces, which are initially deflected elastically when pressing the solenoid valves 1 1, 12 in their slots to then surround an edge of the body of the solenoid valves 12, 13 and so the solenoid valves 12, 13 to fix the shell 10 in a form-fitting manner , Further in the interior of the shell 10 projecting locking hooks 17 serve to secure pipe connections 18 of
Magnetventile. Solenoid valves.
In einer Aussparung der Wand 14 ist ein Steckverbinder 19 verankert. Von den hier vier Polen des Steckverbinders 19 sind je zwei dem Magnetventile 11 bzw. dem Magnetventil 12 zugeordnet und über ein Kabel 20 bzw. 21 mit dem betreffenden Magnetventil 1 1 bzw. 12 verbunden. Die Kabel 20, 21 sind am Steckverbinder 19 vorkonfektioniert, um gemeinsam mit diesem in die Aussparung der Wand 14 eingefügt zu werden. An ihren vom Steckverbinder 19 abgewandten Enden tragen die Kabel 20, 21 jeweils zwei Steckschuhe zum Aufstecken auf plättchenförmige Kontakte der Magnetventile 1 1 , 12, die hier in Gehäusevorsprüngen 22 der Magnetventile 1 1 , 12 verborgen sind. In a recess of the wall 14, a connector 19 is anchored. Of the four poles of the connector 19 are each two the solenoid valves 11 and the solenoid valve 12 associated with and connected via a cable 20 and 21 with the respective solenoid valve 1 1 and 12 respectively. The cables 20, 21 are pre-assembled on the connector 19 to be inserted together with this in the recess of the wall 14. At their ends remote from the connector 19, the cables 20, 21 each carry two plug-in shoes for attachment to plate-shaped contacts of the solenoid valves 1 1, 12, which are hidden here in housing projections 22 of the solenoid valves 1 1, 12.
Zwischen ins Innere der Schale 10 vorspringenden Rippen 23 und der Wand 13 sind mehrere Spalte 24 gebildet, in denen die Kabel 20, 21 geklemmt sind. So sind die Kabel 20, 21 auf ihrer gesamten Länge weitgehend unbeweglich fixiert, und es besteht keine Gefahr, dass, wenn die Baugruppe der Fig. 2 im Kältegerät montiert wird, ein Kabel ungeschützt aus der Schale 10 herausragt oder zwischen den Wänden der Schale 10 und der Wand des Maschinenraums 5 geklemmt wird. Between in the interior of the shell 10 projecting ribs 23 and the wall 13 a plurality of gaps 24 are formed, in which the cables 20, 21 are clamped. Thus, the cables 20, 21 are fixed substantially immovably over their entire length, and there is no danger that when the assembly of FIG. 2 is mounted in the refrigerator, a cable protrudes unprotected from the shell 10 or between the walls of the shell 10th and the wall of the engine room 5 is clamped.
Die Länge der Kabel 20, 21 ist so bemessen, dass, wenn der Steckverbinder 19 in seiner Aussparung, unweit einer vom Magnetventil 12 abgewandten Stirnwand 25 der Schale 10 montiert ist, nur das Kabel 21 lang genug ist, um das Magnetventil 12 zu kontaktieren. Da es folglich nur eine Art und Weise gibt, wie die Magnetventile 1 1 , 12 elektrisch kontaktiert werden können, sind Fehler beim Kontaktieren der Magnetventile 1 1 , 12 ausgeschlossen. Die Stirnwand 25 trägt eine in Fig. 2 perspektivisch, in Fig. 3 in einer Draufsicht auf die Stirnwand gezeigte Rasteinrichtung 26, die zur Verankerung der Magnetventilbaugruppe 8 am Kältegerätekorpus 2 dient. Die Rasteinrichtung 26 hat in etwa die Form eines Quaders, der in Steckrichtung des Steckverbinders 19 langgestreckt und an einem von der Schale abgewandten vorderen Ende zur Erleichterung des Einführens in eine The length of the cables 20, 21 is dimensioned so that when the connector 19 is mounted in its recess, not far from a side facing away from the solenoid valve 12 end wall 25 of the shell 10, only the cable 21 is long enough to contact the solenoid valve 12. Since there is consequently only one way in which the solenoid valves 11, 12 can be electrically contacted, errors in contacting the solenoid valves 11, 12 are excluded. The end wall 25 carries a in Fig. 2 in perspective, in Fig. 3 in a plan view of the end wall shown latching device 26 which serves to anchor the solenoid valve assembly 8 on the refrigerator body 2. The latching device 26 has approximately the shape of a cuboid, which is elongated in the insertion direction of the connector 19 and at one of the shell facing away from the front end to facilitate insertion into a
Rastaussparung des Korpus 2 verjüngt ist. Zwei Seitenwände der Quaderform sind durch von der Stirnwand 25 abstehende, radial zur Steckrichtung langgestreckte Rippen 27 gebildet. Eine Rastzunge 28 bildet eine von der Stirnwand 25 abgewandte Seite des Quaders. Die Rastzunge 28 ist nur über ihr vorderes Ende mit der Rasteinrichtung 26 verbunden und elastisch in einen Freiraum zwischen den Rippen 27 hinein auslenkbar. An ihrem rückwärtigen Ende trägt die Rastzunge 28 einen Vorsprung 29. An einer in der Perspektive der Fig. 2 vom Betrachter abgewandten Rückseite des Vorsprungs 29 ist eine Aussparung gebildet, in die ein Werkzeug, z.B. ein Schraubenzieher, eingeführt werden kann, um die Rastzunge 28 auszulenken.  Locking recess of the body 2 is tapered. Two side walls of the parallelepiped shape are formed by ribs 27 projecting from the end wall 25 and elongated radially to the insertion direction. A latching tongue 28 forms a side facing away from the end wall 25 side of the cuboid. The latching tongue 28 is connected only via its front end with the latching device 26 and elastically deflectable into a free space between the ribs 27 inside. At its rear end, the latching tongue 28 carries a projection 29. At a rear side of the projection 29 facing away from the viewer in the perspective of FIG. 2, a recess is formed into which a tool, e.g. a screwdriver can be inserted to deflect the latching tongue 28.
Fig. 3 zeigt die Schale 10 in einer Draufsicht auf die Stirnwand 25. Man erkennt eine Aussparung 30 der Stirnwand, die vorgesehen ist, um im montierten Zustand eine Rohrleitung des Magnetventils 1 1 aufzunehmen sowie den Steckverbinder 19, der zum Teil über den Umriss der Stirnwand 25 übersteht, um in einen komplementären 3 shows the shell 10 in a plan view of the end wall 25. It can be seen a recess 30 of the end wall, which is provided to receive a pipe of the solenoid valve 1 1 in the mounted state and the connector 19, the part of the outline of the End wall 25 projects to a complementary
Steckverbinder des Korpus 2 einzugreifen. Der Steckverbinder 19 hat hier einen in etwa würfelförmigen Grundkörper 31 aus Kunststoff, von dem mehrere Hülsen 32 abstehen, in denen sich jeweils ein metallischer Kontaktstift erstreckt. An den Grundkörper 31 ist ein zweiarmiger Hebel 33 angeformt, von dem ein Arm als Widerhaken 34 geformt ist und der andere Arm 35 durch ein in der Figur nicht sichtbares Fenster der Wand 14 zugänglich ist, um durch Schwenken des Hebels 33 den Widerhaken 34 von einer Rastkante des komplementären, korpusseitigen Steckverbinders lösen zu können. Connector of the body 2 to intervene. The connector 19 here has a roughly cube-shaped main body 31 made of plastic, projecting from the plurality of sleeves 32, in each of which extends a metallic contact pin. To the main body 31, a two-armed lever 33 is formed, of which one arm is formed as a barb 34 and the other arm 35 is accessible through a not visible in the figure window of the wall 14 to pivot by the lever 33, the barb 34 of a Detach locking edge of the complementary, body-side connector.
Fig. 4 zeigt in einer perspektivischen Ansicht einen Ausschnitt einer aus Kunststoff geformten Auskleidung des Maschinenraums 5 mit einer Einbaunische für die Fig. 4 shows in a perspective view a section of a molded plastic lining of the engine room 5 with a niche for the
Magnetventilbaugruppe 8 im Maschinenraum 5. In einer von der Decke 35 und der Seiten- oder Rückwand 9 des Maschinenraums 5 begrenzten Ecke springen drei Wandplatten 37, 38, 39 vor. Die beiden äußeren Wandplatten 37, 39 tragen jeweils zwei horizontale, spiegelbildlich zueinander orientierte Rippen 40. Zwischen den von der Rückwand 9 abgewandten Enden der Rippen 40 erstreckt sich ein Schlitz 41. Die mittlere Wandplatte 38 ist von den Abmessungen kleiner als die beiden äußeren Wandplatten 37, 39, ist aber wie die Wandplatte 39 mit Rippen 40 und einem Schlitz 41 versehen, die den entsprechenden Rippen 40 und dem Schlitz 41 der Wandplatte 37 spiegelbildlich gegenüberliegen. Zwischen den Wandplatten 37, 38 befindet sich der bereits erwähnte, zum Steckverbinder 19 komplementäre, korpusseitige Steckverbinder 42 mit vier Buchsen 43 und einem Schlitz 44, in dem der Widerhaken 34 verrastbar ist. Solenoid valve assembly 8 in the engine room 5. In a bounded by the ceiling 35 and the side or rear wall 9 of the engine room 5 corner three wall plates 37, 38, 39 before. The two outer wall panels 37, 39 each carry two horizontal, mirror image mutually oriented ribs 40. Between the rear wall 9 remote from the ends of the ribs 40 extends a slot 41. The middle wall plate 38 is smaller in size than the two outer wall panels 37th , 39, but like the wall plate 39, is provided with ribs 40 and a slot 41 which are mirrored to the corresponding ribs 40 and the slot 41 of the wall plate 37. Between the wall plates 37, 38 is the already mentioned, to the connector 19 complementary, body-side connector 42 with four sockets 43 and a slot 44 in which the barb 34 is latched.
Beim Einbau der Magnetventilbaugruppe 8 werden die Rasteinrichtungen 26 in die zwischen den Rippen 40 an den Wandplatten 37, 38 gebildeten Nuten eingeschoben, bis die Spitzen der Rasteinrichtungen 26 gegen einen Anschlag 45 stoßen und die When installing the solenoid valve assembly 8, the locking devices 26 are inserted into the formed between the ribs 40 on the wall plates 37, 38 grooves until the tips of the locking devices 26 abut against a stop 45 and the
Vorsprünge 29 ihrer Rastzungen 28 in die Schlitze 41 der Wandplatten 37, 39 einrasten und der Widerhaken 34 des Steckverbinders 19 sich im Schlitz 44 verhakt. Folglich ist die Schale 10 an drei Punkten am Korpus 2 verankert und sicher fixiert. Sie wieder zu lösen, ist nur möglich, wenn gleichzeitig durch Drücken gegen den Arm 35 der Widerhaken 34 gelöst wird und mit Hilfe eines zwischen die Wandplatten 37, 39 und die Stirnwände 25 der Schale 10 eingeführten Werkzeugs wie etwa eines Schraubenziehers die Vorsprünge 29 aus den Schlitzen 41 herausgezogen werden.  Protrusions 29 of their locking tongues 28 engage in the slots 41 of the wall plates 37, 39 and the barb 34 of the connector 19 hooked in the slot 44. Consequently, the shell 10 is anchored at three points on the body 2 and securely fixed. To solve it again, is only possible if at the same time by pressing against the arm 35 of the barb 34 is released and with the aid of a between the wall plates 37, 39 and the end walls 25 of the shell 10 imported tool such as a screwdriver, the projections 29 from the Slits 41 are pulled out.
Die mittlere Wandplatte 38 ist beim Einbau der in Fig. 2 gezeigten Magnetventilbaugruppe 8 funktionslos. Der Zweck der Wandplatte 38 liegt darin, dass sie, wenn die The middle wall plate 38 is without function when installing the solenoid valve assembly 8 shown in Fig. 2.
