Definitions

  • the invention refers to a refrigerator with a device for rapid cooling of an object.
  • an object of room temperature e.g. a bottle or a can containing a beverage
  • it can take several hours for the object to be cooled down to a desired temperature.
  • the object of the invention is to bring about a refrigerator with a device for rapid cooling of an object in it.
  • a first container having a flexible wall and arranged at a surface of the evaporator of the refrigerator
  • a second container having a flexible wall and arranged in the refrigerator at a lower level than the first container and containing a liquid
  • a pipe through which the liquid can move between the containers
  • a first means for compressing the second container so that the liquid flows up to the first container
  • a second means for bringing the object into contact with the first container which by that is brought into contact with said surface, so that heat can be conducted from the object through the liquid in the first container to the surface.
  • CH-A-281 565 which corresponds to US-A-2 664 716, is known a refrigerated room in which rigid containers containing an eutectic solution are used for quick freezing of objects in the shape of food packages.
  • the eutectic solution of the containers is allowed to freeze in the room after which the containers are brought into contact with new packages introduced into the room thereby rapidly cooling them during melting of the eutectic solution.
  • the cooling of the objects will not become as effective as at the present invention where the objects are brought in very close thermal contact with the evaporator via the flexible wall of the first container and the liquid in it.
  • fig. 1 shows a front view of a refrigerator, the door of which having been removed for the sake of clearness, with the device cooling a bottle
  • fig. 2 shows a side view of the device arranged at an evaporator in the refrigerator
  • fig. 3 shows how a holder has been turned out from the evaporator for receiving a bottle to be cooled rapidly
  • fig. 4 shows the holder pressing the bottle against a bag containing a liquid
  • fig. 5 shows the device with the bottle when the liquid has flowed out of the bag
  • fig. 6 shows a sectional view according to the marking VI-VI in fig. 2.
  • a refrigerator which is refrigerated by a surface 12 of an evaporator, which constitutes a part of a conventional, not shown refrigerant circuit of the refrigerator.
  • a bag 14, see fig. 6, is suspended along the surface 12 in a frame 16, which is connected to a horizontal plate 18, below which a bag 20 containing a liquid is arranged.
  • the bags 14 and 20 communicate with each other through a vertical pipe 22, which extends from an opening 23 in the bag 20 up through the bag 14.
  • a horizontal plate 24 is arranged below the bag 20.
  • the plate 24, see fig. 2, is connected to the plate 18 through a horizontal hinge axis 30 at the outer end of the plate 24.
  • a holder 32 with a concave surface 33 for keeping an object to be cooled is arranged in front of the bag 14 and is between its ends turnably journalled around a horizontal axis 34 relative to the plate 18.
  • a link 36 connects the inner end of the plate 24 with one end of the holder 32.
  • a compression spring 38 is arranged between the plates 18 and 24 and strives to keep these plates away from each other and by that keep the holder 32 in a vertical position in front of the bag 14.
  • the liquid is in fig. 2 located in the bag 20 up to a level 40 in the pipe 22.
  • the surface 12 of the evaporator in a refrigerator can have a temperature which is as low as -30°C.
  • the liquid is therefore chosen so that it will not freeze at this temperature.
  • the bottle is prevented from being too cold by the liquid slowly flowing back to the bag 20 through the opening 28 in the pipe 22 so that the thermal contact between the bottle and the surface 12 via the liquid gradually ceases. In fig. 5 said thermal contact has ceased by the liquid having sunk back to the level 40.
  • the pipe 22 or some other suitable heat insulating spacing element which is located between the surface 12 and the bottle 44, prevents the bottle from getting direct contact with the surface 12 via the walls of the empty bag 14.
  • the plate 18 with the device for rapid cooling according to the invention can be constituted by a shelf, which in conventional way is insertable in and adjustable in vertical direction in horizontal grooves 48 of the inner side walls of the refrigerator 10.

Claims (4)

  1. Réfrigérateur (10) avec un dispositif pour le refroidissement rapide d'un objet (44), comprenant un premier conteneur (14) ayant une paroi souple et agencé à une surface (12) d'un évaporateur du réfrigérateur, un second conteneur (20) ayant une paroi souple et agencé dans le réfrigérateur à un niveau inférieur à celui du premier conteneur et contenant un liquide, un tuyau (22) à travers lequel le liquide peut se déplacer entre les conteneurs, un premier moyen (24) pour comprimer le second conteneur (20), de sorte que le liquide coule jusqu'au premier conteneur (14), et un second moyen (32) pour amener l'objet (44) en contact avec le premier conteneur (14), qui est ainsi amené en contact avec ladite surface (12), de sorte que de la chaleur puisse être conduite de l'objet (44) à travers le liquide dans le premier conteneur (14) à la surface (12).
  2. Réfrigérateur selon la revendication 1, caractérisé en ce que le tuyau (22), qui permet au liquide de couler sans empêchement à partir du second conteneur (20) jusqu'au premier conteneur (14), s'étend de manière verticale à travers le premier conteneur (14) et débouche (26) au-dessus dans le premier conteneur, et en ce que le tuyau (22) au-dessous dans le premier conteneur est équipé d'une petite ouverture (28) qui amène le liquide à refluer lentement du premier conteneur (14) dans le second conteneur (20).
  3. Réfrigérateur selon la revendication 1 ou 2, caractérisé en ce que les seconds moyens consistent en un support (32), qui, à l'aide d'un ressort (38), maintient l'objet (44) en contact avec le premier conteneur (14).
  4. Réfrigérateur selon la revendication 3, caractérisé en ce que le premier moyen (24) est connecté au support (32) de sorte que le premier moyen (24) comprime le second conteneur (20), quand le support (32) est éloigné du premier conteneur (14) contre l'action du ressort (38).
