Definitions

  • This invention relates to refrigerators, and in particular has application in both domestic and commercial refrigerators.
  • Typical refrigerators are accessed via a door which could be hinged either on the left or right hand side with a vertical axis. Opening the door to the refrigerator, reveals the refrigeration compartment, which usually includes a number of shelves most of which are made in the form of a grille, usually metal with a plastic coating. These shelves are used for placement of items in the refrigerator.
  • This invention has as its object, the provision of improvements inefficiency of operation of such refrigerators.
  • a refrigerator having at least one refrigeration compartment being divisible into a plurality of refrigeration storage areas by at least one fixed or removable shelf, at least one of said at least one shelf being arranged to allow free flow of air within said refrigeration compartment; a door assembly arranged to close said refrigeration compartment to retain refrigerated air therein; wherein said door assembly includes an upper door and a lower door, each extending substantially across the width of said refrigeration compartment, said upper door being openable independently of said lower door to provide access to an upper refrigeration storage area within said refrigeration compartment, and wherein said door assembly includes sealing means extending between said upper door and said lower door.
  • said door assembly includes means securing said upper door for movement with the lower door when the lower door is opened by a user.
  • a user may open the upper door while the lower door remains closed, or may open the lower door and the upper door together by opening the lower door.
  • the means securing the upper door for movement with the lower door may include a latching arrangement that has a mechanism in the upper door that is actuated to unlatch the upper door from the lower door when a user pulls on a handle for opening the upper door.
  • the means securing the lower door may include an alternate mechanism in the lower door that secures the lower door to the upper door by latching the lower door to the upper door when a user pulls on a handle for opening the lower door.
  • the means securing the lower door comprises an upwardly extending portion that interferes with a lower part of the upper door, so that the upper door opens with the lower door.
  • the upwardly extending portion extends substantially across the entire top of the upper door for the extent of the width of the refrigeration compartment opening.
  • the upwardly extending portion comprises a lip located across the top of the lower door.
  • sealing means is formed by said upper door supporting a seal which contacts against said lip.
  • said lip may support said seal which contacts against a lower portion of said upper door.
  • seal and lip interact magnetically, to hold the upper door and lower doors together when being closed by a user.
  • This could preferably be achieved in known manner using seals containing magnetic strips.
  • Figure 1 is an orthogonal view of a refrigerator according to the first embodiment of the invention
  • Figure 2 is an orthogonal view of a refrigerator according to the second embodiment of the invention, and;
  • Figure 3 is a cross section of the sealing arrangement utilised in both embodiments.
  • the fridge freezer has a cabinet 13, which is divided into a freezer compartment (not shown) and a refrigeration compartment 15.
  • the freezer compartment has a door 17, and can be accessed by pulling on a handle 19.
  • the freezer compartment and refrigeration compartment 15 are separate enclosures.
  • the refrigeration compartment 15 has, in this embodiment, three shelves formed of a wire grill coated in plastic, the spaces between the wire in the shelves allowing free flow of air within the refrigeration compartment 15.
  • a slide out drawer 23 under the bottom shelf 21 is provided for vegetable storage, as is a common practice in the art.
  • the refrigerator has a door assembly 25 which comprises an upper door 27 and a lower door 29. Both the upper door 27 and the lower door 29 have a handle 31 (not visible on the upper door due to the upper door 27 being shown in a more fully open position).
  • While the shelves 21 in the refrigerator may be adjustable in position, as is known in the art, it is desirable to have the upper shelf 21 placed approximately at the same level as the top of the lower door 29.
  • a plastic magnetic fridge door seal 35 extends around the periphery of all of the doors 17, 27, and 29, to contact against the exposed surface of the front face 37 of the refrigerator cabinet 13 the seal 35 can be best seen as it is shown attached to the upper door 27. Note that due to the provision of a retaining shelf 39 on the inside of the upper door 27, the seal 35, which extends entirely along the underside of the upper door 27, cannot clearly be seen. However, the seal that extends along the lower surface of the upper door 27, is arranged to contact against the facing surface of the lip 33 on the lower door 29, and thereby provide a seal between the upper door and the lower door, assisting in the sealing of the refrigeration compartment 15.
  • Both doors can be closed, either by pushing on the upper door 27, or if the magnetic attraction between the seal 35 and the lip 33 is sufficient, perhaps by pushing on the lower door 29 only.
  • the sealing arrangement between the upper door 27 and lower door 29 provided by the seal 35 and lip 33 there is no need to provide panel work associated with the refrigeration compartment body which would need to extend across the opening and would need to be wide enough to seal both doors. Such panel work extending across the opening would impede access to the refrigeration compartment.
  • the sealing arrangement between the two doors provides less impediment to accessing the refrigeration compartment when both doors are open.
  • the second embodiment is similar to the first embodiment, except that it does not have a freezer compartment (not illustrated in the refrigerator in Figure 1), nor a freezer door 17.
  • the refrigerator is dedicated entirely to refrigerating to a normal refrigerator temperature of from +1 °C to +6°C, in the normal manner.
  • like parts are illustrated with like numerals.
  • the only departure in the second embodiment from the shelving arrangement of the first embodiment is that the refrigerator of the second embodiment incorporates a glass shelf 41 located above the drawer 23.
  • FIG. 3 a cross sectional view of the refrigerator, through the vertical extent of the seal 35, and at the junction of the upper door 27 and lower door 29 is illustrated.
  • the invention could be applied to the type of glass door refrigerator often used commercially in restaurants, cafes, and bars, with the more popular beverages stored behind the upper door, and less accessed items stored behind the lower door.

Abstract

L'invention concerne un réfrigérateur (11) comportant au moins un compartiment (15) de réfrigération qui peut être divisé en une pluralité de zones de stockage réfrigérées par au moins une clayette (21) fixe ou amovible. Les clayettes (21) sont conçues pour permettre à l'air de s'écouler librement dans le compartiment (15) de réfrigération. Le réfrigérateur comporte un ensemble porte (25) destiné à fermer le compartiment de réfrigération (15) de façon à retenir l'air réfrigéré à l'intérieur. L'ensemble porte (25) comprend une porte supérieure (27) et une porte inférieure (29) qui se déploient sensiblement dans le sens de la largeur du compartiment (15) de réfrigération. La porte supérieure (27) peut s'ouvrir indépendamment de la porte inférieure (29) pour permettre un accès à la zone de stockage réfrigérée dudit compartiment (15), de sorte qu'on peut accéder aux articles utilisés fréquemment et placés dans la zone de stockage supérieure sans provoquer la perte d'air due à l'ouverture de la porte entière d'un réfrigérateur classique. L'ensemble porte (25) comprend des moyens (33, 35) se déployant entre la porte supérieure (27) et la porte inférieure (29) et qui rendent superflue une structure de fermeture hermétique des portes, intégrée au corps du compartiment de réfrigération et qui obstruerait l'accès lorsque les deux portes (27, 29) sont ouvertes.
