Support for refrigeration grilles

Description

[0001] The present invention relates to a drawer freezer according to the preamble of claim 1. Such a drawer freezer is known from EP-A-0 534 107. More particularly, the invention concerns the support for horizontal refrigeration grilles, i.e. evaporator grilles used for example in drawer freezers.

[0002] In drawer freezers, each drawer is known to be nearly in contact with a section of the evaporator. The section consists of a hairpin coil, the loops of which are joined together by a plurality of metal rods or bars located at both the top and bottom of the loops. This section is known colloquially as a "grille". The grilles are currently supported on inserted supports (separate parts) fixed to the side walls of the freezer preservation compartment.

[0003] The use of these supports involves costs relative to the supports themselves, costs for their assembly and the cost of accessories such as screws or the like.

[0004] A fixing system for horizontal evaporators which uses separate parts cooperating with side walls is shown by WO-A-02/21058.

[0005] The invention remedies this situation by the features of claim 1.

[0006] The supports are formed simultaneously with the vacuum forming of said internal enclosure.

[0007] The supports are substantially formed on a horizontal bar-like part on which the grille rests, i.e. towards the opening of the compartment the bar-like part presents a projection acting as an abutment to prevent extraction of the grille. A second bar-like part is present parallel to the first, but of smaller length, to act as a support for the preservation drawer and define with the first a mouth for the insertion of the grille therebetween during mounting. The abutment extends below the plane of the bar-like part on which the grille rests to act as a stop to limit the extraction travel of the drawer.

[0008] The invention will be more apparent from the ensuing detailed description provided by way of example with reference to the accompanying drawing which shows a perspective partial view of the preservation compartment of a drawer freezer and two relative grilles and relative supports.

[0009] With reference to the figure, the reference numeral 1 indicates overall a drawer freezer showing its preservation compartment. The preservation compartment is bounded by an inner enclosure 2 obtained by vacuum thermoforming. The inner enclosure presents two parallel side walls (only one is visible in the drawing) in which, during the same forming stage as the internal enclosure, lateral guides are formed for the support and retention of grilles positioned at different heights and indicated by 4.

[0010] The guides are indicated overall by 5 and comprise a horizontal bar-like part 6 on which the grille 4 rests. At its front this bar-like part 6 terminates with an abutment 7 preventing involuntary extraction of the grille. Advantageously this abutment can extend downwards with a projecting part 10 for limiting the extraction travel of a drawer, not shown.

[0011] The guides are completed by a further horizontal bar-like part 8 for the support and sliding of the overlying drawer. This further bar-like part 8 is parallel to the first 4, it is of lesser length and forms with the first a channel into which to insert the grille. The insertion operation is facilitated by the lesser axial length of the further bar-like part 8 which leaves between the two bar-like parts a mouth adequate for the installation of the grille by a mixed rotational and axial movement.

[0012] A preferred embodiment of the invention has been illustrated, however others can be conceived within the scope of the claims.

Claims

1. A drawer freezer having a the preservation compartment with side walls (3) provided with supports supporting refrigeration grilles, said preservation compartment comprising a drawer, characterized in that such supports consist of horizontal bar-like conformations (6) directly provided in said side walls (3), the bar-like conformations (6) terminate at their front with an abutment (7), extending downwards (at 10) to act as a limit stop for the drawer.

2. A drawer freezer as claimed in claim 1, wherein other horizontal bar-like conformations (8) of lesser length are provided defining with the first (4) a mouth (9) enabling the grille to undergo its insertion movement.

Ansprüche

1. Schubladen-Tiefkühlgerät mit einem Aufbewahrungs-Kompartiment mit Seitenwänden (3), die mit Stützen versehen sind, welche Kühlgitter abstützen, wobei das Aufbewahrungs-Kompartiment eine Schublade umfasst, dadurch gekennzeichnet, dass diese Stützen aus horizontalen, leistenähnlichen Aufbauten (6) bestehen, die direkt in den Seitenwänden (3) vorgesehen sind, wobei die leistenähnlichen Aufbauten (6) an deren Vorderseite mit einem Anschlag (7) enden, der sich (bei 10) nach unten erstreckt, um als Stopper für die Schublade zu agieren.

2. Schubladen-Tiefkühlgerät wie in Anspruch 1 beansprucht, wobei andere horizontale, leistenähnliche Aufbauten (8) mit kleinerer Länge vorgesehen sind, die mit der ersten Leiste (4) eine Mündung (9) definieren, welche es dem Gitter ermöglichen, seine Einsetzbewegung auszuführen.

Revendications

1. Congélateur à tiroir ayant un compartiment de conservation avec des parois latérales (3) doté de support qui supporte des grilles de réfrigération, ledit compartiment de conservation comprenant un tiroir, caractérisé en ce que lesdits supports sont constitués par des conformations horizontales semblables à des barres (6) prévues directement dans lesdites parois latérales (3), les conformations semblables à des barres (6) se terminant à leur partie avant par une butée (7), s'étendant vers le bas (10) pour faire office d'arrêt-limite pour le tiroir.

2. Congélateur à tiroir selon la revendication 1, dans lequel d'autres conformations horizontales semblables à des barres (8) de plus faible longueur sont prévues, qui définissent avec les premières (4) une embouchure (9) permettant à la grille de subir son mouvement d'insertion.
