- FIG. 2 also shows that part of the air separates from the vertically rising flow to be distributed to the shelves by passing over the goods schematized at 14 in FIGS. 1 and 2 and joining the vertical curtain 11.
- the curtain of cold air is taken up at the bottom of the cabinet by a recovery device 15 at the upper edge of the front wall 16 of the tank 3, under the effect of the fans 7.
- FIG. 2 illustrates the presence of a second air curtain indicated at 18, exterior, that is to say in front of the cold air curtain 11.
- This curtain consists of ambient air taken from the top of the cabinet by a fan 20 and rejected down the aisle at the front of the cabinet.
- the secondary curtain 18 is not cooled.
- FIGs 3 to 6 specifically illustrate the device 15 for recovering cold air from the curtain 11. This device will now be described in more detail with reference to these figures.
- the cold air intake device essentially comprises a horizontal return louver 22, that is to say provided with openings 23 located in a substantially horizontal plane and shaped two rows of aligned slots and a vertical louver 24 having openings 25 arranged in a substantially vertical plane and also in the form of two rows of slots.
- the cold air intake device comprises, between the two horizontal louvers 22 and vertical 24, an inclined face 27, which extends in a 45 ° angle to the horizontal and vertical planes. Thanks to this inclined face 27 the two flows Fa and Fb quickly glue downstream of the recoveries so as to obtain a rapid relaminarization.
- the horizontal and vertical louvers are supported by a plurality of support pieces 28 distributed uniformly along the longitudinal axis of the piece of furniture.
- Figure 5 is a perspective view of such a support piece 28.
- middle portion 29 in the form of a plate which extends perpendicular to one longitudinal axis of the furniture and whose edge rear 30 oriented towards the tank is arched and has the curved shape clearly visible in Figure 4.
- the front edge of the middle part 29 has vertically and horizontally projecting parts 31, 32 which constitute support portions of the blades 34 and 35 horizontal and vertical louvers. Between these two support portions 31 and 32 projecting vertically upward and horizontally outward is provided an intermediate portion 37 in the form of a cross-member which extends laterally on either side of the intermediate part 29, in the direction of the axis of the furniture and has a substantially U-shaped cross section.
- this portion 37 which serves to support a profile 39 whose external free front face constitutes the inclined face 27 anti-detachment, which is interposed between the two horizontal and vertical recoveries of the curtain of cold air.
- the profile 39 comprises, projecting towards the rear, two fins 40 which come into engagement behind the branches 41 of the cross member or support bar 37 when the profile is put in place between the two horizontal and vertical. It should also be noted that, at the level of the upper and lower longitudinal edges, the profile 39 has curved projection 51 allowing the placement of labels not shown.
- the support 28 comprises a part forming a foot 42 allowing it to be fixed to the front wall 16 of the tank.
- This part forming a foot 42 projects laterally on either side of the median part of the support and has, in cross section, the shape of an L whose long arm 43 is applied and fixed against the internal face of the front wall 16 of the tank while the other branch 44 bears on the substantially horizontal upper face of the tank wall.
- the end of the branch 44 is bent at 45 so as to constitute a bracket for fixing the support 28 on the front wall of the tank.
- the support 28 is fixed to the front wall of the tank by screws 46, the through holes of which are indicated at 47 in FIG. 5.
- the support piece 28 carries a horizontal bar 49 for supporting the shelves or trays 4 of the piece of furniture by means of an intermediate profile 50 which extends over the entire length of the piece of furniture and constitutes a lateral limitation wall of the horizontal recovery louver.
- the other lateral wall delimiting the louver is formed by the upper edge 51 of the front anti-separation profile 39.
- the lower edge 51 constitutes a side delimiting side of the vertical recovery louver delimited on the other side by a second lower strip 35. The strips are each inserted into a slot in the support.
