Description

Die Erfindung bezieht sich auf einen Kühlschrank und dergleichen mit mindestens einem Thermostaten dessen Fühler die Temperatur einer Verdampferfläche erfaßt, wobei die Verbindung zwischen Fühler und Thermostat durch ein Rohr geführt ist, das zumindest teilweise hinter der Innenwandung, vorzugsweise innerhalb der Isolierung verlegt ist.The invention relates to a refrigerator and the like with at least one thermostat whose sensor detects the temperature of an evaporator surface, the connection between the sensor and the thermostat being guided through a pipe which is at least partially laid behind the inner wall, preferably inside the insulation.

Bei Kühlschränken ist es bekannt, die Verbindungskapillare zwischen Fühler und Thermostat zumindest über einen Teil ihrer Länge in einem Rohr zu führen. Dieses Rohr kann an der Rückseite der Innenwandung des Kühlraumes geführt und eingeschäumt sein. Der Fühler ist durch die Wandung zum Verdampfer geführt und an diesen befestigt. Der Fühler ist sichtbar und stört beim Reinigen des Kühlraumes.In refrigerators, it is known to guide the connecting capillary between the sensor and thermostat at least over part of its length in a tube. This tube can be guided and foamed in on the back of the inner wall of the cooling space. The sensor is led through the wall to the evaporator and attached to it. The sensor is visible and disturbs when cleaning the refrigerator.

Auch bei Kühlschränken, bei denen der Verdampfer eingeschäumt ist, hat man den Fühler auf der Verdampferfläche im Kühlraum anliegend befestigt. Der Fühler ist wiederum sichtbar und ist beim Reinigen des Kühlraumes hinderlich.Even in refrigerators in which the evaporator is foamed in, the sensor has been attached to the evaporator surface in the refrigerator compartment. The sensor is visible again and is a hindrance when cleaning the refrigerator.

Der Erfindung liegt die Aufgabe zugrunde, einen Kühlschrank der beschriebenen Art anzugeben, bei dem der Temperaturfühler leicht ausgetauscht werden kann und die Innenfläche des Kühlraumes bei sicherer Temperaturerfassung frei von Fühlerelementen bleibt.The invention has for its object to provide a refrigerator of the type described, in which the temperature sensor can be easily replaced and the inner surface of the cooling room remains free of sensor elements with reliable temperature detection.

Diese Aufgabe wird bei der gattungsgemäßen Kältemaschine gamäß der Erfindung dadurch gelöst, daß auf der Rückseite die Innenwandung bis zu dem dort angebrachten Verdampfer geführt und dort so anliegend befestigt ist, daß ein eingeschobener Fühler dessen Oberflächentemperatur ex rast.This object is achieved in the generic refrigeration machine according to the invention in that on the back the inner wall is guided up to the evaporator attached there and is fastened there so that a inserted probe whose surface temperature rages ex.

Bei der erfindungsgemäßen Kältemaschine verläuft das Rohr über die ganze Länge verdeckt in der Wand des Kühlschrankes, so daß sie nicht sichtbar ist. Dadurch sind die Innenwände des Kühlraumes glatt, so daß sie ohne Schwierigkeiten gereinigt werden können. Es besteht auch nicht die Gefahr, daß der Fühler und/oder das Rohr beim Reinigungsvorgang beschädigt werden. Da der Verdampfer an der Rückwand des Kühlraumes anliegt, ist auch im Bereich des Verdampfers eine einfache Reinigung der Kühlraumwand gewährleistet. Das Rohr wird mit der Halterung in der Einbaulage zuverlässig gesichert. Der im Rohr untergebrachte Fühler hingegen kann herausgezogen werden, so daß eine einfache Reparatur am Fühler bzw. ein rascher Austausch des Fühlers möglich ist. Ein neuer Fühler läßt sich ohne Schwierigkeiten durch das Rohr bis zum Verdampfer hin einführen.In the refrigeration machine according to the invention, the tube runs in the wall of the refrigerator over the entire length, so that it is not visible. As a result, the inner walls of the cold room are smooth so that they can be cleaned without difficulty. There is also no risk that the sensor and / or the pipe will be damaged during the cleaning process. Since the evaporator rests on the rear wall of the cold room, easy cleaning of the cold room wall is also ensured in the area of the evaporator. The pipe is reliably secured with the bracket in the installed position. The sensor housed in the tube, on the other hand, can be pulled out, so that simple repair to the sensor or rapid replacement of the sensor is possible. A new sensor can be easily inserted through the pipe to the evaporator.

Im Ausführungsbeispiel ist das Innengehäuse 1 eines Kühlschrankes mit einer nicht gezeichneten Isolierung umgeben. Das Gehäuse 1 hat ein Gefrierfach 2, das von einem Verdampferblech 3 umgeben ist. Ein weiteres Verdampferblech 4 ist an der Rückwand 5 des Gehäuses 1 befestigt. Dieses Verdampferblech 4 ist mit dem Verdampferblech 3 verbunden. An das Verdampferblech 4 ist der Fühler 60 eines (nicht dargestellten) Thermostaten angeschlossen, der im Kühlraum des Kühlschrankes angeordnet ist. Der Fühler 60 ist in einem Rohr 6 untergebracht, das vorzugsweise flexibel ausgebildet ist, so daß es je nach den Einbauverhältnissen und der Ausbildung des Gehäuses 1 verlegt werden kann. Nahe seinem freien Ende ist das Rohr 6 mit einer Halterung 7 am Verdampfer 4 und/oder am Gehäuse 1 befestigt.In the exemplary embodiment, the inner housing 1 of a refrigerator is surrounded by insulation (not shown). The housing 1 has a freezer compartment 2, which is surrounded by an evaporator plate 3. Another evaporator plate 4 is attached to the rear wall 5 of the housing 1. This evaporator plate 4 is connected to the evaporator plate 3. The sensor 60 of a thermostat (not shown) is connected to the evaporator plate 4 and is arranged in the refrigerator cooling compartment. The sensor 60 is housed in a tube 6, which is preferably flexible, so that it can be installed depending on the installation conditions and the design of the housing 1. Near its free end, the tube 6 is fastened to the evaporator 4 and / or to the housing 1 with a holder 7.

Der Zwischenraum zwischen dem Gehäuse 1 und einem nicht gezeichneten Korpus wird mit Isolationsmaterial ausgeschäumt. Das Rohr 6 wird hierbei mit eingeschäumt, befindet sich also vollständig in der Isolation. Die Verdampferbleche 3 und 4 sind ebenfalls in die Isolation eingeschäumt und liegen mit ihren Innenseiten in der Innenwandung des Gefrierfaches 2 bzw. des Kühlraumes plan an. Die Halterung 7 hat einen im Grundriß im wesentlichen rechteckigen Grundkörper 8 mit einem U-förmigen Querschnitt. Er hat einen ebenen Steg 9 und rechtwinklig dazu Schenkel 10 und 11, welche die Längsseitenwände des Grundkörpers 8 bilden (Fig. 5). An den Schmalseiten des Grundkörpers 8 sind ebenfalls senkrecht zum Steg 9 verlaufende Wände 12 und 13 vorgesehen (Fig. 4), die gleiche Höhe wie die Schenkel 10, 11 haben und mit ihnen verbunden sind. Der Grundkörper 8 mit dem ebenen Steg 9 und den ebenen Seitenwänden 10 bis 13 ist somit wannenförmig ausgebildet. Um den Grundkörper 8 zu versteifen, kann er mit wenigstens einer Versteifungsrippe versehen sein, die sich zwischen den Schenkeln 10 und 11 erstreckt.The space between the housing 1 and a body, not shown, is filled with insulation material. The tube 6 is foamed in here, so it is completely in the insulation. The evaporator sheets 3 and 4 are also foamed into the insulation and lie flat with their inner sides in the inner wall of the freezer compartment 2 and the refrigerator compartment. The holder 7 has a substantially rectangular base 8 with a U-shaped cross section. It has a flat web 9 and at right angles to legs 10 and 11, which form the longitudinal side walls of the base body 8 (FIG. 5). On the narrow sides of the base body 8 there are also walls 12 and 13 running perpendicular to the web 9 (FIG. 4), which have the same height as the legs 10, 11 and are connected to them. The base body 8 with the flat web 9 and the flat side walls 10 to 13 is thus trough-shaped. In order to stiffen the base body 8, it can be provided with at least one stiffening rib which extends between the legs 10 and 11.

Mit geringem Abstand vom Schenkel 11 ist an der Halterung 7 ein im Querschnitt U-förmiges Lagerteil 14 vorgesehen, das einen ebenen Steg 15 und senkrecht abstehende Schenkel 16 und 17 aufweist (Fig. 5). Das angeformte Lagerteil 14 ist gleich lang wie der Grundkörper 8 (Fig. 2) und hat in Draufsicht ebenfalls rechteckigen Umriß. Der Abstand zwischen den Schenkeln 16 und 17 ist an den Außendurchmesser des Rohres 6 angepaßt, das zwischen den beiden Schenkeln verlegt wird.At a short distance from the leg 11, a bearing part 14 with a U-shaped cross section is provided on the bracket 7, which has a flat web 15 and vertically projecting legs 16 and 17 (FIG. 5). The integrally formed bearing part 14 is the same length as the base body 8 (FIG. 2) and also has a rectangular outline in plan view. The distance between the legs 16 and 17 is adapted to the outer diameter of the tube 6, which is laid between the two legs.

Zwischen den einander benachbarten Schenkeln 11 und.16 ist eine rechteckige Nut 22 gebildet. Da das Rohr 6 üblicherweise kreisförmigen Querschnitt hat, kann der Steg 15 des Lagerteiles 14 auch derart gekrümmt sein, daß er in der Einbaulage flächig am Rohr 6 anliegt.A rectangular groove 22 is formed between the adjacent legs 11 and 16. Since the tube 6 usually has a circular cross section, the web 15 of the bearing part 14 can also be curved such that it lies flat against the tube 6 in the installed position.

Von den Seitenwänden 12 und 13 des Grundkörpers 8 steht jeweils ein etwa dreieckförmiger Steg 23 und 24 annähernd senkrecht ab (Fig. 2). Mit geringem Abstand vom Lagerteil 14 steht von den Seitenwänden 12 und 13 des Grundkörpers 8 jeweils eine Rippe 27 und 28 ab, die senkrecht zum Steg 23, 24 sowie zu den Seitenwänden 12 und 13 verläuft. Wie Fig. 3 zeigt, nimmt die Höhe der Rippe 27 von der Seitenwand 12 des Grundkörpers 8 aus nach außen stetig ab. Die Höhe der Rippe 28 nimmt von der Seitenwand 13 aus zunächst ab und bleibt dann etwa ab der halben Länge der Rippe konstant. Im Anschlußbereich an die Seitenwände 12 und 13 haben die Rippen 27 und 28 gleiche Höhe wie diese Wände.An approximately triangular web 23 and 24 projects from the side walls 12 and 13 of the base body 8 approximately vertically (FIG. 2). At a short distance from the bearing part 14, a rib 27 and 28 protrudes from the side walls 12 and 13 of the base body 8, which is perpendicular runs to the web 23, 24 and to the side walls 12 and 13. 3 shows, the height of the rib 27 decreases steadily from the side wall 12 of the base body 8 to the outside. The height of the rib 28 initially decreases from the side wall 13 and then remains constant from approximately half the length of the rib. In the connection area to the side walls 12 and 13, the ribs 27 and 28 have the same height as these walls.

Die Rippe 27 ist etwa in halber Länge unter einem geringen Winkel in Richtung auf den Schenkel 10 abgewinkelt. Die gegenüberliegende Rippe 28 weist etwa in halber Länge einen vorzugsweise rechtwinkligen Absatz 31 auf, der in ein ebenfalls in Richtung auf den Schenkel 10 des Grundkörpers 8 schräg verlaufendes Rippenstück 32 übergeht. An den abgewinkelten Teil der Rippe 27 schließt auf der vom Steg 23 abgewandten Seite ein Auflager 34 an, dessen Unterseite (Fig. 3) in einer Ebene mit den Stirnseiten der Schenkel 10 und 11 des Grundkörpers 8 liegt. Die Oberseite des Auflagers 34 ist als Schrägfläche ausgebildet, die in Richtung auf das freie Ende der Rippe 27 ansteigt.The rib 27 is angled approximately in half length at a slight angle in the direction of the leg 10. The opposite rib 28 has approximately a half length of a preferably right-angled shoulder 31 which merges into a rib piece 32 which also runs obliquely in the direction of the leg 10 of the base body 8. The angled part of the rib 27 is adjoined on the side facing away from the web 23 by a support 34, the underside (FIG. 3) of which lies in one plane with the end faces of the legs 10 and 11 of the base body 8. The top of the support 34 is formed as an inclined surface which rises in the direction of the free end of the rib 27.

An das abgewinkelte Rippenstück 32 schließt ebenfalls ein Auflager 40 rechtwinklig an, dessen Unterseite (Fig. 3) in einer Ebene mit der Unterseite des anderen Auflagers 34 liegt und deren Oberseite als Schrägfläche ausgebildet ist. Auf dem Auflager 40 ist eine Rippe 43 vorgesehen, die parallel zum Rippenstück 32 verläuft. Das Rippenstück 32 und die Rippe 43 begrenzen eine U-förmige Aufnahme.A support 40 also adjoins the angled fin piece 32 at right angles, the underside (FIG. 3) of which lies in one plane with the underside of the other support 34 and the top of which is designed as an inclined surface. A rib 43 is provided on the support 40 and runs parallel to the rib piece 32. The rib piece 32 and the rib 43 delimit a U-shaped receptacle.

Die gesamte Halterung 7 ist vorteilhaft einstückig aus Kunststoff hergestellt. Sie bildet eine Vormontageeinheit, die vor der Befestigung am Gehäuse 1 bereits mit dem Rohr 6 bestückt werden kann.The entire bracket 7 is advantageously made in one piece from plastic. It forms a pre-assembly unit, which can already be fitted with the tube 6 before being attached to the housing 1.

Zunächst wird der Thermostat an der Innenseite des Kühlraumes montiert und das Rohr 6 durch die Wand 48 (Fig. 1) des Gehäuses 1 geführt. Das flexible Rohr 6 wird dann so in die Halterung 7 eingesetzt, daß es durch die Ausnehmung 49 (Fig. 2) zwischen dem Lagerteil 14 und dem Rippenstück 32 und der Rippe 43 verläuft. Anschließend wird das Rohr 6 in die gegenüberliegende Ausnehmung 50 zwischen dem Lagerteil 14 und dem Auflager 34 gesteckt. In dieser Lage verläuft das flexible Rohr im Bereich unterhalb des Lagerteils bogenförmig. Anschließend wird dieser gebogene Teil zwischen die Schenkel 16 und 17 des Lagerteiles 14 gedrückt. Da die Auflager 34 und 40 mit den Schrägflächen 36 und 42 versehen sind, die entgegengesetzt voneinander schräg verlaufen, wird das Rohr 6 im Bereich zwischen dem Lagerteil 14 und den jeweiligen Auflagern verspannt, so daß die Halterung 7 fest auf dem Rohr 6 sitzt. Da das Rippenstück 32 und die Rippe 43 schräg zur Längsachse des Lagerteiles 14 liegen, wird das Rohr 6 nicht nur nach oben, sondern auch seitlich gebogen, wodurch ein sicherer Sitz der Halterung 7 auf dem Rohr 6 erreicht wird. Der Abstand zwischen den Schenkeln 16 und 17 des Lagerteiles 14 ist vorzugsweise geringfügig kleiner als der Durchmesser des Rohres 6, so daß der im Lagerteil 14 liegende Teil des Rohres zwischen den Schenkeln verspannt wird. Die Halterung 7 sitzt darum sicher auf dem Rohr 6 in der jeweiligen Lage. Um ein Abknicken des Rohres 6 im Austrittsbereich aus dem Lagerteil 14 zu verhindern, ist der Steg 15 im Austrittsbereich an seiner Unterseite 51 mit Abschrägungen 52 und 53 versehen (Fig. 4).First, the thermostat is mounted on the inside of the cooling space and the pipe 6 is guided through the wall 48 (FIG. 1) of the housing 1. The flexible tube 6 is then inserted into the holder 7 in such a way that it runs through the recess 49 (FIG. 2) between the bearing part 14 and the fin piece 32 and the fin 43. The tube 6 is then inserted into the opposite recess 50 between the bearing part 14 and the support 34. In this position, the flexible pipe runs in an arc in the area below the bearing part. This bent part is then pressed between the legs 16 and 17 of the bearing part 14. Since the supports 34 and 40 are provided with the inclined surfaces 36 and 42, which run obliquely opposite one another, the tube 6 is clamped in the area between the bearing part 14 and the respective supports, so that the holder 7 sits firmly on the tube 6. Since the rib piece 32 and the rib 43 lie obliquely to the longitudinal axis of the bearing part 14, the tube 6 is not only bent upwards but also laterally, as a result of which the holder 7 is securely seated on the tube 6. The distance between the legs 16 and 17 of the bearing part 14 is preferably slightly smaller than the diameter of the tube 6, so that the part of the tube lying in the bearing part 14 is clamped between the legs. The holder 7 therefore sits securely on the tube 6 in the respective position. In order to prevent the pipe 6 from kinking in the outlet area from the bearing part 14, the web 15 is provided with bevels 52 and 53 on its underside 51 in the outlet area (FIG. 4).

Die so am Rohr 6 vormontierte Halterung 7 wird dann am Gehäuse 1 oder dem Verdampfer 4 befestigt. Die Halterung 7 wird mit ihren Schenkeln 10 und 11 auf das Gehäuse 1 an der Einbaustelle aufgesetzt und beispielsweise mit Ultraschall an ihm angeschweißt. Die Halterung kann aber auch auf jede andere geeignete Weise mit dem Gehäuse 1 verbunden werden. Vorzugsweise wird die Halterung 7 im Randbereich des Verdampferbleches 4 befestigt. Es hat eine rechtwinklig herausgebogene Lasche 54 (Fig. 5), die in die Nut 22 zwischen dem Lagerteil 14 und dem Grundkörper 8 eingreift. Dadurch wird das Verdampferblech 4,im Randbereich durch die Halterung 7 zusätzlich gegen Ablösen vom Gehäuse 1 gesichert. Im übrigen ist das Verdampferblech 4 mittels einer Klebefolie 55 auf dem Gehäuse 1 befestigt.The bracket 7 thus pre-assembled on the tube 6 is then attached to the housing 1 or the evaporator 4. The bracket 7 is placed with its legs 10 and 11 on the housing 1 at the installation site and for example with Ultra sound welded to him. The holder can also be connected to the housing 1 in any other suitable manner. The holder 7 is preferably fastened in the edge region of the evaporator sheet 4. It has a tab 54 (FIG. 5) which is bent out at right angles and engages in the groove 22 between the bearing part 14 and the base body 8. As a result, the evaporator plate 4 is additionally secured in the edge region by the holder 7 against detachment from the housing 1. Otherwise, the evaporator plate 4 is fastened to the housing 1 by means of an adhesive film 55.

Durch das Lagerteil 14 der Halterung 7 wird das Rohr 6 über eine ausreichend große Länge fest gegen das Verdampferblech 4 gedrückt, so daß eine ausreichende Kontaktfläche sichergestellt ist. Das verdampferseitige Ende 61 des Rohres.ist geschlossen. Das Rohr 6 wird so in bezug auf die Halterung 7 angeordnet, daß es aus dem Lagerteil 14 so weit herausragt, daß Längentoleranzen des Fühlers 60 ausgeglichen werden können. Der Überstand des Rohres 6 ist also so groß, daß auch unter Berücksichtigung der Längentoleranzen der Fühler 60 über die gesamte Länge des Lagerteiles 14 verläuft.Through the bearing part 14 of the holder 7, the tube 6 is pressed firmly against the evaporator plate 4 over a sufficiently large length, so that a sufficient contact area is ensured. The evaporator end 61 of the tube is closed. The tube 6 is arranged with respect to the holder 7 that it protrudes from the bearing part 14 so far that length tolerances of the sensor 60 can be compensated. The protrusion of the tube 6 is so large that, taking into account the length tolerances, the sensor 60 extends over the entire length of the bearing part 14.

Im Reparaturfalle läßt sich der Fühler 60 einfach aus dem Rohr 6 herausziehen und ein neuer Fühler mühelos einschieben.In the event of repairs, the sensor 60 can simply be pulled out of the tube 6 and a new sensor can be inserted effortlessly.
