Description

Kältegerät mit Luftkanal  Refrigerating appliance with air duct
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit einem Luftkanal, in dem Luft von oder zu einer Lagerkammer des Kältegeräts, insbesondere zwischen einer Lagerkammer und einer Verdampferkammer, fließt. The present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, with an air duct in which air flows from or to a storage chamber of the refrigeration appliance, in particular between a storage chamber and an evaporator chamber.
Aus EP 1 144 927 B1 ist ein Haushaltskältegerät bekannt, bei dem ein Luftkanal, über den Kaltluft in einer Lagerkammer des Kältegeräts verteilt wird, in eine Rückwandfläche und eine Seitenwandfläche eines die Lagerkammer umschließenden Innenbehälters eingetieft und von der Lagerkammer durch in Öffnungen der Wandflächen eingerastete Abdeckplatten getrennt ist. Die Abdeckplatten haben eine komplizierte dreidimensionale Gestalt, mit einer Mehrzahl von Durchgangsöffnungen und mit Rasthaken zur From EP 1 144 927 B1 a household refrigerating appliance is known, in which an air channel, is distributed over the cold air in a storage chamber of the refrigerator, recessed into a rear wall surface and a side wall surface of the storage chamber enclosing inner container and from the storage chamber through in openings of the wall surfaces latched cover plates is disconnected. The cover plates have a complicated three-dimensional shape, with a plurality of through holes and with latching hooks for

Eine solche Abdeckplatte kann aus Kunststoff spritzgeformt werden, doch sind hierfür komplizierte Werkzeuge erforderlich, deren Kosten um so höher sind, je größer die Abdeckplatte ist. Für Kältegeräte mit Anchoring the cover plate. Such a cover plate can be injection molded from plastic, but this complicated tools are required, the cost is higher, the larger the cover plate. For refrigerators with
unterschiedlichen Gehäusemaßen werden jeweils unterschiedliche Abdeckplatten benötigt, so dass zu ihrer Fertigung auch spezifische Werkzeuge bereitgestellt werden müssen. Aufgabe der Erfindung ist, ein Kältegerät mit einem eine Lagerkammer umschließenden wärmeisolierenden Gehäuse und einem in eine Wandfläche des Gehäuses eingetieften und mit der Lagerkammer über Öffnungen einer sich zwischen dem Luftkanal und der Lagerkammer erstreckenden Platine kommunizierenden Luftkanal anzugeben, das mit unterschiedlichen Gehäuseabmessungen preiswert und rationell gefertigt werden kann. different Gehäusemaßen different cover plates are required, so that specific tools must be provided for their production. The object of the invention is to provide a refrigerator with a storage chamber enclosing a heat-insulating housing and a recessed into a wall surface of the housing and communicating with the storage chamber via openings of a extending between the air duct and the bearing chamber board communicating air duct, which made inexpensive and efficient with different housing dimensions can be.
Unter einem Kältegerät wird insbesondere ein Haushaltskältegerät verstanden, also ein Kältegerät das zur Haushaltsführung in Haushalten oder eventuell auch im Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the
Gastronomiebereich eingesetzt wird, und insbesondere dazu dient Lebensmittel und/oder Getränke in haushaltsüblichen Mengen bei bestimmten Temperaturen zu lagern, wie beispielsweise ein Kühlschrank, ein Gefrierschrank, eine Kühlgefrierkombination, eine Gefriertruhe oder ein Weinlagerschrank. Die Aufgabe wird gelöst, in dem bei einem solchen Kältegerät die Platine an der Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer, a freezer or a wine storage cabinet. The problem is solved in which in such a refrigerator, the board at the
Wandfläche durch wenigstens einen Bügel fixiert ist, der ein an einer der Lagerkammer zugewandten Seite der Platine anliegendes Mittelstück und von dem Mittelstück ausgehende, durch wenigstens eine Öffnung der Platine hindurch in Hinterschneidungen des Luftkanals eingreifende Rasthaken umfasst. Da erfindungsgemäß der Bügel die Aufgabe übernimmt, die den Luftkanal überdeckende Platine zu fixieren, braucht diese nicht ihrerseits mit Rasthaken versehen zu sein. Die Form der Platine kann daher deutlich einfacher sein als die der herkömmlichen Abdeckplatte, so dass eine Fertigung der Platine im Spritzguss nicht erforderlich ist. Vielmehr kann die Platine einfach aus Wall surface is fixed by at least one bracket which comprises a resting on one of the bearing chamber side facing the board centerpiece and emanating from the center piece, engaging through at least one opening of the board in undercuts of the air channel locking hooks. Since according to the invention, the bracket takes on the task of fixing the air duct overlapping board, this need not be provided in turn with snap hooks. The shape of the board can therefore be much simpler than that of the conventional cover plate, so that a production of the board in the injection molding is not required. Rather, the board can simply turn off
Flachmaterial zugeschnitten werden. Dies ermöglicht es, die Platine in unterschiedlichen Abmessungen, passend für unterschiedliche Gehäuseabmessungen des Kältegeräts, bereitzustellen, ohne dass zur Fertigung der Platine für die jeweilige Gehäusegröße spezifische Werkzeuge erforderlich wären. Im bevorzugten, einfachsten Falle ist die Platine eben, so dass außer dem erwähnten Zuschneiden keinerlei Bearbeitung des Flachmaterials erforderlich ist, um die Platine zu fertigen. Be cut flat material. This makes it possible to provide the board in different dimensions, suitable for different housing dimensions of the refrigeration device, without requiring specific tools for the manufacture of the board for the respective housing size. In the preferred, simplest case, the board is flat, so that no editing of the sheet is required except for the above-mentioned cutting to manufacture the board.
Wenn die Abmessungen der Platine groß sind, kann es erforderlich sein, sie an mehreren Stellen entlang des Luftkanals zu befestigen. Vorzugsweise sind hierzu mehrere identische Bügel verwendet. Da deren Abmessungen zwangsläufig dadurch kleiner sind als die der Platine, ist für die Bügel eine Fertigung im Spritzguss wirtschaftlich. Da die Bügel in großer Zahl und in verschiedenen Kältegerätemodellen in identischer Gestalt zum Einsatz kommen können, können sie rationell und preiswert bereitgestellt werden. If the dimensions of the board are large, it may be necessary to secure them in several places along the air duct. Preferably, several identical brackets are used for this purpose. Since their dimensions are inevitably smaller than that of the board, a manufacturing in injection molding is economical for the bracket. Since the stirrups can be used in large numbers and in different refrigerator models in identical shape, they can be provided efficiently and inexpensively.
Vorzugsweise liegen die Hinterschneidungen, in die die Rasthaken eines Bügels eingreifen, sich an zwei Seitenwänden des Luftkanals gegenüber, so dass die Rasthaken sich gegenseitig in den Hinterschneidungen im Eingriff halten können. Vorzugweise stehen die Rasthaken, wenn sie in die Hinterschneidungen eingreifen, unter Vorspannung, um die Platine spielfrei gegen die Wandfläche des Gehäuses gedrückt zu halten, in die der Luftkanal eingetieft ist. Der Bügel kann an seiner der Platine zugewandten Seite einen flachen Vorsprung aufweisen, der die von wenigstens einem Rasthaken durchsetzte Öffnung der Platine ausfüllt, so dass die Platine durch den Eingriff des Vorsprungs in Richtung ihrer Preferably, the undercuts, in which engage the latching hooks of a bracket, are opposite to two side walls of the air channel, so that the latching hooks can hold each other in the undercuts in engagement. Preferably, the locking hooks, when they engage in the undercuts, are biased to hold the board without play against the wall surface of the housing, in which the air duct is recessed. The bracket may have on its side facing the board a flat projection which fills the at least one locking hook interspersed opening of the board, so that the board by the engagement of the projection in the direction of her
Oberfläche unbeweglich gehalten ist. Surface is held immovable.
Der Überstand des Vorsprungs sollte nicht größer sein als die Stärke der Platine, um ein zu Turbulenz und Druckabfall führendes Eingreifen des Vorsprungs in den Luftkanal zu vermeiden. Optimale Strömungsbedingungen im Luftkanal sind insbesondere dann realisierbar, wenn der Überstand des Vorsprungs der Stärke der Platine entspricht, so dass eine Scheitelfläche des Vorsprungs und eine dem Luftkanal zugewandte Innenfläche der Platine im Wesentlichen bündig aneinander anschließen. The projection protrusion should not be greater than the thickness of the board to avoid turbulence and pressure drop engagement of the protrusion into the air channel. Optimum flow conditions in the air duct can be realized, in particular, if the projection of the projection corresponds to the thickness of the board, so that a vertex surface of the projection and an inner surface of the board facing the air duct are substantially flush with one another.
Der Bügel kann ausschließlich der Fixierung der Platine dienen; vorzugsweise jedoch weist er eine mit einer der Öffnungen der Platine überlappende Öffnung auf, um den Durchtritt von Luft zwischen dem Luftkanal und der Lagerkammer zu ermöglichen. Diese Öffnung kann dieselbe sein, durch die sich auch wenigstens einer der Rasthaken erstreckt, es kann sich aber auch um jeweils verschiedene Öffnungen handeln. The bracket can only serve to fix the board; preferably, however, it has an opening overlapping one of the openings of the board to allow the passage of air between the air channel and the storage chamber. This opening may be the same, through which also extends at least one of the latching hooks, but it may also be each different openings.
Die Öffnung des Bügels kann insbesondere als Düse geformt sein, um einen aus dem Luftkanal in die Lagerkammer eintretenden Luftstrom zu steuern. The opening of the stirrup may in particular be shaped as a nozzle in order to control an air flow entering the storage chamber from the air duct.
Vorzugsweise sind die Hinterschneidungen in Längsrichtung des Luftkanals von Preferably, the undercuts are in the longitudinal direction of the air channel of
Wandbereichen begrenzt, die nicht oder zumindest schwächer als besagte Wall areas limited, not or at least weaker than said
Hinterschneidungen hinterschnitten sind. Auf diese Weise sind die Bügel jeweils nur an bestimmten Stellen des Luftkanals montierbar, und ein Verrutschen der Platine und der Bügel entlang des Kanals sowie Fehler bei der Anbringung der Bügel und der Platine können vermieden werden. Undercuts are undercut. In this way, the brackets are each only mountable at certain points of the air duct, and slippage of the board and the bracket along the channel and errors in the attachment of the bracket and the board can be avoided.
Um die Position der Bügel und der Platine in Längsrichtung des Luftkanals exakt festzulegen, ist vorzugsweise die Breite der in die Hinterschneidungen eingreifendenIn order to define the position of the bracket and the board exactly in the longitudinal direction of the air duct, preferably the width of the engaging in the undercuts
Rasthaken entsprechend der Breite der Hinterschneidungen selbst gewählt, so dass eine Verschiebung der Rasthaken in den Hinterschneidungen in Längsrichtung des Luftkanals ausgeschlossen ist. Das Fehlen von Spalten zwischen den Rasthaken und den entlang des Luftkanals vor und hinter den Rasthaken liegenden Wandbereichen trägt außerdem zur Minimierung von Turbulenz im Luftkanal bei. Latch hook selected according to the width of the undercuts itself, so that displacement of the locking hooks in the undercuts in the longitudinal direction of the air channel is excluded. The absence of gaps between the snap hook and the along The air duct in front of and behind the latch hook wall areas also contributes to the minimization of turbulence in the air duct.
Um Turbulenz zu verringern, ist es ferner zweckmäßig, wenn dem Inneren des Luftkanals zugewandte Flanken der Rasthaken im Wesentlichen bündig an die sich vor und hinter den Hinterschneidungen erstreckenden Wandbereiche des Luftkanals anschließen. In order to reduce turbulence, it is also expedient if flanks of the latching hooks facing the interior of the air duct are substantially flush with the wall regions of the air duct extending in front of and behind the undercuts.
Um eine sichere Verrastung trotz geringer Wandstärke zu ermöglichen, ist der Bügel vorzugsweise durch wenigstens eine abstehende Rippe versteift. Diese Rippe sollte vorzugsweise an der der Lagerkammer zugewandten Seite des Bügels angeordnet sein, um den Strom der Luft im Luftkanal nicht zu beeinträchtigen. In order to enable a secure locking despite small wall thickness, the bracket is preferably stiffened by at least one protruding rib. This rib should preferably be arranged on the bearing chamber facing side of the bracket, so as not to affect the flow of air in the air duct.

Das in Fig. 1 in einem schematischen Querschnitt gezeigte Kältegerät ist ein No-Frost- Haushaltskühlschrank mit einem wärmeisolierenden Gehäuse, das in fachüblicher Weise einen Korpus 1 und eine daran angeschlagene Tür 2 umfasst, die einen Innenraum begrenzen, der durch eine Zwischenwand 3 in eine Lagerkammer 4 für Kühlgut und eine Verdampferkammer 5 unterteilt ist. Ein Kältemittelkreislauf umfasst in ebenfalls an sich bekannter Weise einen in der Verdampferkammer 5 angeordneten Verdampfer 6, einen in einer rückseitigen Nische des Korpus 1 untergebrachten Verdichter 7 und einen The refrigerator shown in a schematic cross-section in Fig. 1 is a no-frost household refrigerator with a heat-insulating housing, which includes in a usual way a body 1 and an attached door 2, which delimit an interior, by an intermediate wall 3 in a Storage chamber 4 for refrigerated goods and an evaporator chamber 5 is divided. A refrigerant circuit comprises in a manner also known per se an evaporator 6 arranged in the evaporator chamber 5, a compressor 7 accommodated in a rear recess of the body 1 and a compressor
Verflüssiger 8. Ein in der Verdampferkammer 5 untergebrachter Lüfter 9 saugt Luft aus der Lagerkammer 4 über Öffnungen 10 in einen türnahen Bereich der Zwischenwand 3 in die Verdampferkammer 5 ein und drückt am Verdampfer 6 abgekühlte Luft in einen Luftkanal 1 1 , der, in die Innenseite einer Rückwand 12 des Korpus 1 eingetieft, sich von der Verdampferkammer 5 aus vertikal abwärts erstreckt. Der Luftkanal 1 1 erstreckt sich in Breitenrichtung des Korpus 1 nur über einen mittleren Bereich der Rückwand 12. Er ist von der Lagerkammer 4 durch eine ebene Platine 13 getrennt, von der seitliche Abschnitte beiderseits des Luftkanals 1 1 , d.h. bezogen auf die Darstellung der Fig. 1 vor und hinter der Schnittebene, an der Innenfläche der Rückwand 12 anliegen. Die Breite der Platine 13 ist variabel, sie muss mindestens geringfügig breiter als der Luftkanal 1 1 sein, um beiderseits von diesem sicher an der Rückwand 13 anzuliegen, und sie kann maximal der Breite der Innenseite der Rückwand 13 Condenser 8. A housed in the evaporator chamber 5 fan 9 sucks air from the storage chamber 4 through openings 10 in a near-door area of the intermediate wall 3 in the evaporator chamber 5 and presses the evaporator 6 cooled air in an air duct 1 1, the, in the inside a rear wall 12 of the body 1 is recessed, vertically extending from the evaporator chamber 5 downwards. The air duct 1 1 extends in the width direction of the body 1 only over a central region of the rear wall 12. It is separated from the storage chamber 4 by a planar board 13, from the lateral portions on either side of the air duct 1 1, i. 1, in front of and behind the cutting plane, rest on the inner surface of the rear wall 12, based on the representation of FIG. The width of the board 13 is variable, it must be at least slightly wider than the air duct 1 1 to abut on both sides of this safely on the rear wall 13, and it can not exceed the width of the inside of the rear wall 13th
entsprechen. In die Platine 13 sind in vertikaler Richtung gleichmäßig beabstandete Öffnungen 14 geschnitten. Dies und die Variabilität der Breite der Platine machen es möglich, Platinen für eine Vielzahl von Kältegerätemodellen mit unterschiedlichen Gehäuseabmessungen zu fertigen, indem ein Flachmaterialband in regelmäßigen Abständen mit eingestanzten Öffnungen versehen wird und Stücke in jeweils der Länge des zu überdeckenden Luftkanals entsprechender Länge von dem Band geschnitten werden. correspond. In the circuit board 13 evenly spaced openings 14 are cut in the vertical direction. This and the variability of the width of the board make it possible to manufacture boards for a variety of refrigeration models with different housing dimensions by having a flat material strip at regular intervals with punched openings and pieces in the length of the corresponding length of air duct to be covered by the band get cut.
Die Platine 13 ist an der Rückwand 12 mit Hilfe von Bügeln 15 befestigt, die jeweils ein an der der Lagerkammer 4 zugewandten Seite der Platine 13 anliegendes Mittelstück sowie durch die von dem Mittelstück verdeckte Öffnung 14 hindurchgreifende und an The board 13 is attached to the rear wall 12 by means of brackets 15, each one on the storage chamber 4 facing side of the board 13 fitting center piece and through the covered by the central opening 14 and on
Seitenwänden des Luftkanals 1 1 verankerte Rasthaken aufweisen. Side walls of the air duct 1 1 have anchored latching hooks.
Die Bügel 15 sind hier jeweils mit einer düsenförmigen Öffnungen dargestellt, die geformt ist, um durch die Öffnung in die Lagerkammer 4 austretende Kaltluft zu einem sich im Wesentlichen horizontal in Richtung der Tür 2 ausbreitenden Strahl zu formen. Denkbar ist jedoch auch, einzelne der Bügel 15 durch (in den Figuren nicht dargestellte) Bügel mit einem geschlossenen Mittelstück zu ersetzen, welches die von den Rasthaken des Bügels durchgriffene Öffnung 14 der Platine 13 im Wesentlichen dicht verschließt. Fig. 2 veranschaulicht die Verankerung der Platine 13 an der Rückwand 12 anhand eines horizontalen Schnitts in vergrößertem Maßstab. Die in die Lagerkammer 4 hineinragende düsenförmige Öffnung des Bügels 15 ist hier mit 18 bezeichnet, und beiderseits der Öffnung 18 greifen vom Mittelstück 16 des Bügels 15 ausgehende haarnadelartig gekrümmte Rasthaken 17 in den Luftkanal 1 1 ein. An den Seitenwänden des Luftkanals 1 1 sind Hinterschneidungen 19 geformt, in die die Rasthaken 17 eingreifen. Die The brackets 15 are here each shown with a nozzle-shaped openings which is shaped to form through the opening into the storage chamber 4 exiting cold air to a substantially horizontally propagating in the direction of the door 2 beam. It is also conceivable, however, to replace individual of the bracket 15 by (not shown in the figures) bracket with a closed center piece, which closes the attacked by the locking hooks of the bracket opening 14 of the board 13 substantially tight. Fig. 2 illustrates the anchoring of the board 13 on the rear wall 12 by means of a horizontal section on an enlarged scale. The projecting into the bearing chamber 4 nozzle-shaped opening of the bracket 15 is here designated by 18, and on both sides of the opening 18 engage from the central portion 16 of the bracket 15 outgoing hairpin-like curved locking hooks 17 in the air duct 1 1 a. On the side walls of the air duct 1 1 undercuts 19 are formed, in which engage the latching hooks 17. The
Rasthaken 17 sind zwischen den Seitenwänden unter Vorspannung gehalten, so dass eine elastische Spannung des Bügels 15, die die Rasthaken 17 auseinandertreibt, das Mittelstück 16 gegen die Rückwand 12 zieht und so die Platine 13 zwischen dem  Latch hooks 17 are held under bias between the side walls, so that an elastic tension of the bracket 15, which drives apart the latching hooks 17, the center piece 16 pulls against the rear wall 12 and so the board 13 between the
Mittelstück 16 und der Rückwand 12 geklemmt hält. Middle piece 16 and the rear wall 12 holds clamped.
Anhand des nochmals vergrößerten Schnitts der Fig. 3 ist zu erkennen, dass die With reference to the further enlarged section of Fig. 3 it can be seen that the
Hinterschneidungen 19 jeweils nur kurze Abschnitte der Seitenwände des Luftkanals 1 1 einnehmen und in Längsrichtung des Luftkanals 1 1 beiderseits von Wandbereichen 20 flankiert sind, die entweder gar nicht oder schwächer als die Hinterschneidungen 19 hinterschnitten sind. Wenn die Wandbereiche 20 gar nicht hinterschnitten sind, kann es zwar möglich sein, die Rasthaken 17 eines Bügels 15 zwischen sich gegenüberliegenden Wandbereichen 20 einzuführen, doch findet der Bügel 15 in dieser Stellung keinen festen Halt, und die elastische Verformung, die die Rasthaken 17 beim Hineindrücken in den Luftkanal 1 1 erfahren, treibt den Bügel 15 wieder aus dem Luftkanal 1 1 heraus. Wenn die Wandbereiche 20 nur schwach hinterschnitten sind, kann ein Bügel 15 zwar zeitweilig zwischen ihnen Halt finden, er kann jedoch nicht die Platine 13 gegen die Rückwand 12 drücken, und um festen, dauerhaften Halt zu finden, muss der Bügel 15 entlang des Luftkanals 1 1 verschoben werden, bis seine Rasthaken 17 in Hinterschneidungen 19 einrasten. Undercuts 19 each occupy only short sections of the side walls of the air duct 1 1 and flanked in the longitudinal direction of the air duct 1 1 on both sides of wall portions 20, either not at all or weaker than the undercuts 19th are undercut. If the wall portions 20 are not undercut at all, it may indeed be possible to introduce the latching hooks 17 of a bracket 15 between opposite wall portions 20, but the bracket 15 is not firmly held in this position, and the elastic deformation, the latching hooks 17 at Pressing experienced in the air duct 1 1, drives the bracket 15 back out of the air duct 1 1 out. If the wall portions 20 are only slightly undercut, a bracket 15 may indeed temporarily hold between them, but he can not push the board 13 against the rear wall 12, and to find solid, lasting support, the bracket 15 along the air duct. 1 1 are moved until its locking hooks 17 engage in undercuts 19.
Wie in den Fig. 2 bis 7 zu erkennen, umfassen die Rasthaken 17 jeweils ein im As can be seen in FIGS. 2 to 7, the latching hooks 17 each comprise an im
horizontalen Querschnitt bogenförmiges Endstück 21 , das formschlüssig in eine horizontal cross-section arcuate end 21, the form-fitting in one
Hinterschneidung 19 eingreift, sowie ein dem Querschnittsverlauf der Wandabschnitte 20 folgendes, hier im Querschnitt im Wesentlichen geradliniges, plattenartiges Undercut 19 engages, as well as a the cross-sectional profile of the wall sections 20 following, here in cross-section substantially rectilinear, plate-like
Zwischenstück 22, das an einem Ende mit dem Mittelstück 16 und am Intermediate piece 22, which at one end with the center piece 16 and on
gegenüberliegenden Ende mit dem Endstück 21 verbunden ist. Wie in Fig. 3 zu sehen, entspricht die Breite dieses Zwischenstücks 22 der Breite der Hinterschneidung 19, und das Zwischenstück 22 verläuft im Wesentlichen bündig mit den die Hinterschneidung 19 begrenzenden Wandbereichen 20, so dass die Wandbereiche 20 zusammen mit dem Zwischenstück 22 eine im Schnitt in Längsrichtung des Luftkanals 1 1 im Wesentlichen geradlinige, die zirkulierende Luft nicht verwirbelnde Begrenzung des Luftkanals 1 1 bilden. Die Figuren 4 und 5 zeigen den Bügel 15 in zwei perspektivischen Ansichten, einmal von seiner der Lagerkammer 4 zugewandten Seite her und einmal von der dem Luftkanal 1 1 zugewandten Seite her. Die der Lagerkammer 4 zugewandte Seite des Mittelstücks 16 ist, wie in Fig. 4 zu sehen, im Wesentlichen eben, bis auf einen sich rings um die Öffnung 18 erstreckenden, die durch die Öffnung 18 strömende Luft zu einem Strahl formenden Stutzen 23. An der dem Luftkanal 1 1 zugewandten Seite des Bügels 15 ist rings um die Öffnung 18 ein flacher Vorsprung 24 geformt, von dem auch die Rasthaken 17 ausgehen. Der Umriss des Vorsprungs 24 entspricht der Form der in die Platine 13 geschnittenen Öffnungen 14, so dass, wenn der Bügel 15 in einer dieser Öffnungen 14 montiert ist, Platine 13 und Bügel 15 in zur Oberfläche der Platine 13 parallelen Richtungen gegeneinander unbeweglich sind. Dank des Eingriffs des Vorsprungs 24 in die Öffnung 14 ist, wenn die Rasthaken 17, wie mit Bezug auf Fig. 3 erläutert, an den Seitenwänden des Luftkanals 1 1 formschlüssig einrasten, die Position der Platine 13 an der Rückwand 12 eindeutig festgelegt. opposite end to the end piece 21 is connected. As can be seen in Fig. 3, corresponds to the width of this intermediate piece 22, the width of the undercut 19, and the intermediate piece 22 is substantially flush with the undercut 19 bounding wall portions 20, so that the wall portions 20 together with the intermediate piece 22 in a section in the longitudinal direction of the air channel 1 1 substantially rectilinear, the circulating air not vortexing boundary of the air channel 1 1 form. Figures 4 and 5 show the bracket 15 in two perspective views, once from its the storage chamber 4 side facing and once from the air duct 1 1 side facing. The bearing chamber 4 facing side of the center piece 16 is, as shown in Fig. 4, substantially flat, except for a ring extending around the opening 18, the air flowing through the opening 18 to form a jet-forming nozzle 23. On the the air duct 1 1 facing side of the bracket 15 is formed around the opening 18 a flat projection 24, from which the latching hooks 17 go out. The outline of the projection 24 corresponds to the shape of the openings 14 cut into the circuit board 13, so that when the bracket 15 is mounted in one of these openings 14, the circuit board 13 and bracket 15 in parallel to the surface of the board 13 directions immovable against each other. Thanks to the engagement of the projection 24 in the opening 14, when the latching hooks 17, as explained with reference to FIG. 3, positively engage the side walls of the air duct 11, the position of the circuit board 13 on the rear wall 12 is uniquely determined.
Der Überstand des Vorsprungs 24 über die ihn umgebende Rückseite des Mittelstücks 16 entspricht der Wandstärke der Platine 13, so dass eine Scheitelfläche 25 des Vorsprungs 24 im montierten Zustand bündig mit der den Luftkanal 1 1 begrenzenden Innenfläche 26 der Platine 13 verläuft. Die Innenfläche 26 und die Scheitelflächen 25 der Bügel 15 bilden somit eine kontinuierliche Begrenzung des Luftkanals 1 1 , an der die Luft weitgehend verwirbelungsfrei vorbeistreichen kann. The projection of the projection 24 on the surrounding rear side of the center piece 16 corresponds to the wall thickness of the board 13, so that a vertex surface 25 of the projection 24 in the mounted state is flush with the air duct 1 1 bounding inner surface 26 of the board 13. The inner surface 26 and the apex surfaces 25 of the bracket 15 thus form a continuous boundary of the air duct 1 1, at which the air can pass by largely turbulence.
Die Festigkeit des Sitzes des Bügels 15 im Luftkanal 1 1 und folglich auch die Kraft, mit der die Bügel 15 die Platine 13 gegen die Rückwand 12 gedrückt halten, hängt ab von der Steifigkeit der Rasthaken 17 sowie des sie verbindenden Mittel Stücks 16. Um die The strength of the seat of the bracket 15 in the air duct 1 1 and consequently the force with which the bracket 15 hold the board 13 pressed against the rear wall 12, depends on the rigidity of the latching hooks 17 and the connecting means piece piece 16. To the
Steifigkeit der Rasthaken 17 zu steigern, können Dreieckrippen 27, z.B. wie in Fig. 5 gezeigt, zwischen dem Mittelstück 16 und den Rasthaken 17 vorgesehen sein. To increase rigidity of the latching hooks 17, triangular ribs 27, e.g. As shown in Fig. 5, be provided between the middle piece 16 and the latching hooks 17.
Eine mit geringem Materialaufwand realisierbare Versteifung des Mittelstücks 16 umfasst, wie in Fig. 6 gezeigt, zwei sich beiderseits des Stutzens 23 horizontal erstreckendeAs can be seen in FIG. 6, a stiffening of the middle piece 16 which can be realized with a low material expenditure comprises two horizontally extending on both sides of the connecting piece 23
Rippen 28 an der Vorderseite des Mittelstücks 16 oder, vorzugsweise und wie in Fig. 7 gezeigt, Paare von zueinander parallelen Rippen 28, die sich jeweils im Wesentlichen in Verlängerung von horizontalen oberen und unteren Flanken 29 des Stutzens 23 erstrecken. Ribs 28 on the front of the center piece 16 or, preferably and as shown in Fig. 7, pairs of mutually parallel ribs 28, each extending substantially in extension of horizontal upper and lower edges 29 of the nozzle 23.
