Description

The subject of the present invention is a device for

  mobile refrigerator shutters, this device, intended to be placed in the lower part of a tank of

  refrigerator, to obtain, in the compartment or compartments

  inferior foods in which it is desired to preserve certain foods or beverages, significantly higher temperatures

  as the temperature prevailing in the rest of the refrigerator.

  Indeed, it seems interesting to have at its disposal a refrigerator with one or more compartments in which the temperature may have a value chosen between +50 and +120 for example, while the average temperature of the other compartments of the refrigerator tank is neighbor

from +50.

  In order to obtain in the (or) lower compartment of a refrigerator (crisper for example) temperatures above +50, it is known to limit the flow of refrigerated air in these compartments by isolating them by means of a fixed horizontal partition of dimensions such as its edges

  are very close to the anterior and posterior lateral walls

refrigerator. -

  One way to modify at will the circulation of air in this or these lower compartments is to be able to close more or

  minus the chilled air circulation passages (circula-

  by convection), the latter descending along the rear wall of the refrigerator tank and up along the

the counter door.

  The partitioning device with movable flaps according to the present invention makes it possible to modulate the temperature of the

  lower part of the tank of a refrigerator while preserving

  a substantially constant temperature in the

top of this tank.

  According to the invention, a partition device with movable shutters for a refrigerator, making it possible to vary

  the temperature of at least one compartment of a tank of this refrigerator

  generator, the temperature of the other compartments of the refrigerator vessel having a predetermined value, is characterized in that it comprises a first fixed element of partitioning

- 2468861-

  having the shape of a tray of dimensions such that two of its opposite edges are recessed respectively with respect to two vertical walls vis-à-vis the tank, leaving free, between the first element and the two walls vis-à-vis -vis, air circulation openings, in that a second partitioning element comprising movable flaps is arranged parallel to the fixed element and in that means can simultaneously move the movable flaps

  in order to obtain a desired closure of these openings.

  The invention will be better understood and other characteristics

  will appear with the following description and

  accompanying drawings and in which: - Figure 1 shows a partial view of a refrigerator provided with a partition with movable flaps according to the invention; - Figures 2 and 3 show, in cross section, details of Figure 1 respectively corresponding to two positions of the movable flaps;

  FIG. 4 shows an alternative embodiment of the arrangement

  partitioning system with movable flaps according to the invention.

  Figure 1 shows a partial view of a refrigerator equipped with a horizontal shutter partitioning device

  mobiles according to the invention. This partitioning device

  carries a first element 1 of horizontal fixed partition cooperating with a second element 2 horizontal partition with movable flaps 3, 4 for adjusting the air flow in a (Figures 2, 3) or more (Figure 1) compartments

  C located in the lower part of the refrigerator tank.

  Figures 2 and 3 show the details of a device for

  horizontal partitioning according to the invention.

  The compartment C located in the lower part of the tank R

  of the refrigerator is delimited at its upper part by a first

  first element 1 of horizontal partitioning, fixed, in the form of a plate whose dimensions are such that the front and rear edges 5 and 5 respectively are set back from the vertical walls 7, 8 front and rear of the tank R. Parallel to first element 1 and under this element 1 is disposed a second partition element 2 with movable shutters

  3, 4. These two movable shutters 3 and 4 are nested and present

  respectively on their edges facing each other, situated in a central zone of the compartment C, racks 9, 10 intended to cooperate with a toothed wheel which is movable about an axis 12 fixed on the fixed element 1, substantially in the center of this

  element 1 and perpendicular to it.

  Components 3, 4 are respectively engaged in

  13, 14 lateral sides allowing movement of movable flaps 3 and 4 parallel to these slides 13, 14. The flap

mobile 4 is provided with a pull tab 15.

  In operation, in the position shown in FIG.

  the movable flaps 3, 4 are placed against each other,

  circulate refrigerated air through the front and

  posterior 16, 17-formed between the free edges 5, 6 of the

  1 and the vertical walls 7, 8 of the refrigerant tank R

  tor. If it is desired to reduce the cold air circulation in the compartment C and thus obtain a higher temperature in this compartment C than in the rest of the tank, it draws in the direction of the arrow on the pull tab 15, causing a simultaneous movement (FIG. 3) of the shutter 3 towards the rear,

  that is to say towards the front vertical wall 7 of refrigeration

  R, and the flap 4 forwards, that is to say towards the counter-

  door 8, thus desirably decreasing the openings 16, 17

  anterior and posterior air circulation.

  In a variant shown in FIG. 4, a plate 18

  thermally insulating material (expanded polystyrene, for example

  ple) is arranged between the elements 1 and 2. This plate 18

  can be fixed on the fixed element 1, ensuring a good insulation

  between the compartment C and the upper part of the tank when the shutters 3 and 4 are separated one of

  the other. The plate 18 has substantially the dimensions of the element 1.

  In the example shown in FIG. 1, the refrigerator R is provided with a partitioning device with movable flaps 3, 4, but it may be advantageous to include in the tank several compartments comprising a partitioning device with movable shutters according to FIG. invention, thus making it possible to

  the lower part of the compartment vat at temperatures

  different eratures (for example between + 5 and + 120) and

  suitable for the preservation of various food products.
