Definitions

  • the subject of the present invention is an adjustable partitioning device with movable shutters for a device for producing cold, such as a refrigerator for example, this device intended to be placed in the lower part of the refrigerated enclosure such as the tank of the refrigerator. , making it possible to obtain, in the lower compartment or compartments in which it is desired to store certain particular foods (vegetables) or certain drinks (wines), temperatures substantially higher than the temperature prevailing in the rest of the refrigerator.
  • a device for producing cold such as a refrigerator for example
  • a refrigerator comprising one or more compartments in which the temperature can have a value chosen between + 5 ° and + 12 ° for example, while the average temperature of the other compartments, or compartments normally refrigerated, the refrigerator bowl is around + 5 °.
  • Such differentiation can also be useful in a freezer where the lower, less cold compartment can be used to store less cold food.
  • the wall 12 which separates the two compartments which it is desired to adjust at different temperatures comprises, towards the rear , openings 13 which can be closed by a movable wall 14 operated by a zipper 16.
  • openings 13 When the openings 13 are released, a little cold air descends and the lower compartment reaches its coldest temperature.
  • this device does not allow an adjustable circulation of air by convection.
  • cold air can descend (the cold source is in the upper compartment) through the openings 13, an equivalent quantity of heated air cannot go up towards the cold compartment.
  • US patent US-A-2 493 488 describes shelves intended to separate from a compartment B cooled by its evaporator 15, a compartment E where ice cubes are made and which has its own cold source: auxiliary evaporator 17. Openings 20 are arranged on either side of the shelves 16; their only function described (and possible) is to allow water vapor to descend to the lower compartment E. No heat exchange is planned between the two compartments which each have their cold source.
  • the devices of the state of the art do not make the best use of the physical property which causes the cold air to descend while the warmer air rises.
  • the invention uses this property to make air circulation more efficient thanks to an adjustable partitioning device having, in its open position, at least one opening at the rear of the tank where the cold source is located, to the descent of the cold air and at least one opening at the front of the tank for the rise of the heated air, these openings always having practically the same dimensions at the front and at the rear and whatever adjustment.
  • the partitioning device with movable shutters according to the present invention makes it possible to modulate the temperature of the lower part of the tank of a refrigerator while maintaining a substantially constant temperature in the upper part of this tank.
  • an adjustable partitioning device with movable flaps for cold production apparatus intended to separate more or less, normally refrigerated compartments, at least one compartment located relative to the cold production zone, to the part bottom of the appliance, this compartment which can thus be less cold than the compartments normally refrigerated and at an adjustable temperature
  • it comprises a fixed partition element having dimensions such that it leaves, at the rear of the device where the cold source is located, at least one adjustment opening allowing the cold air produced therein to descend and, at the front of the device, at least one adjustment opening of dimensions equivalent to those of the rear opening allowing the return of the heated air to the upper part of the appliance where the cold is produced, and in that it also comprises at least two movable shutters capable of closing the at least more or less respectively two openings, these at least two movable flaps being mechanically coupled by coupling means such that the displacement of one causes the displacement of the other in the opposite direction, so as to simultaneously open or close the openings by the same amount.
  • Figure 1 shows a partial view of a refrigerator equipped with an adjustable horizontal partitioning device with movable shutters according to the invention.
  • it is an appliance for producing refrigeration, such as a refrigerator. But it could just as easily be a freezer. It may indeed be useful to have, at the bottom of a freezer one (or more) compartment which is used, as desired, as a freezer like the rest of the appliance, or as a preservative, that is to say at a temperature slightly higher than that of the rest of the device.
  • the partitioning device of the invention comprises a first element 1 of fixed horizontal partitioning cooperating with a second element 2 of horizontal partitioning with movable flaps 3, 4 allowing the adjustment of the air circulation in one (FIGS. 2, 3) or several (Figure 1) compartments C located in the lower part of the refrigerator tank.
  • Figures 2 and 3 show the details of a horizontal partitioning device according to the invention.
  • the fixed partition element 1 is formed by a horizontal plate fixed to the side walls of the tank R of the refrigerator and has dimensions such that its rear 5 and front 6 edges are set back from the wall. vertical 7 posterior and against the door 8 of the tank R.
  • this fixed partition element 1 leaves, at the rear of the tank, an opening 16 letting down the cold air produced by the refrigerator, in its upper part where the evaporator is (not shown), and at the front an opening 17 allowing the return to the upper part of the device of the heated air.
  • the invention also covers a variant in which these two openings could each be replaced by several openings.
  • the plate constituting the fixed partition element 1 would extend towards the front and towards the rear of the refrigerator and would be pierced, in the two zones corresponding to these openings 16 and 17, with several openings.
  • the important point for the proper functioning of the present invention is that there is at least one air passage, on the one hand at the rear 16 of the refrigerator and on the other hand at the front 17, so that , when the lower compartment (s) must be as cold as the rest, the refrigerated air circulates there properly.
  • a second partition element 2 Parallel to the first element 1 and, advantageously, under this element, is mounted a second partition element 2 with movable shutters 3, 4.
  • the two movable flaps 3 and 4 have a generally square shape, are nested and have respectively on their opposite edges, located in the central zone of compartment C, toothed parts forming racks 9, 10 intended to cooperate with a toothed wheel 11 movable about an axis 12 fixed on the fixed element 1, substantially at the center of this element 1 and perpendicular to it.
  • the flaps 3, 4 are engaged respectively in lateral slides 13, 14 allowing movement of the mobile flaps 3 and 4 parallel to these slides 13, 14.
  • the mobile flap 4 is provided with a pull tab 15.
  • a plate 18 of thermally insulating material is disposed between the elements 1 and 2.
  • This plate 18 can be fixed on the fixed element 1, ensuring good thermal insulation between the compartment C and the upper part of the tank when the flaps 3 and 4 are separated from one another.
  • the plate 18 has substantially the dimensions of the element 1.
  • the refrigerator R is provided with a partitioning device with movable shutters 3, 4 but it may be advantageous to include in the tank several compartments comprising a partitioning device with movable shutters according to the invention, thus making it possible to produce compartments at the lower part of the tank at different temperatures (for example between + 5 ° and + 12 °) and suitable for the conservation of various food products.
