The invention relates to refrigeration equipment, in particular to a vertical display case with a curtain of cooled air from the front of the display case in front of the exposed food that contains, essentially, the high part to exit the cooled air and the device, re-taking the air, which is located at the level of the upper edge of the front wall of the camera exhibit showcases and has openings for the re-air intake, located essentially in the horizontal plane, using a fan system provided in the camera.

Known display Cabinet with cooling, in particular vertical display Cabinet, which is made with a curtain of cooled air in front of the exhibit showcase, before exhibited food contains, essentially, a high part to exit the cooled air and the device, re-taking the air containing holes located essentially in a horizontal plane and designed to re-air intake under the action of the fan system provided in the camera (Patent Fr No. 245825 And 47 F 3/04,1981).

The main drawback of the exhibit showcase, performed according to the described embodiment, is that the horizontal device, re-superaudiocd, creates the need to increase the width of the exhibit showcases at a relatively large value beyond its useful space exposure of food.

The present of the invention is to create an exhibit showcase with cooling, in which is fixed the above disadvantage.

The problem is solved in that the device for re-air intake contains in addition to the holes for re-sampling, which are located in a plane essentially horizontal holes to re-air intake located in a plane essentially vertical.

According to a variant implementation of the invention the holes to re-horizontal air intake and vents for repeated vertical air intake part of the blinds respectively horizontal and vertical, and, in addition, the inclined surface designed to prevent delamination of the curtain of air is provided between the blinds to re-horizontal and vertical air intake.

Other goals, options, complete, details and advantages of the invention will be clear from the following explanatory description with reference to schematic drawings, given only as an example illustrating an embodiment of the invention, which is:

- figure 1 represents a General view of the exhibition showcases with cooling according to the invention;

- figure 2 represents a schematic view in vertical section and perpendicular to the vertical axis exhibit showcases with cooled, made according to the invention;

- figure 5 shows a General view of a support roller shutters in accordance with figure 4;

- figure 6 depicts a view similar to the view presented in figure 4 another variant implementation supports blinds according to the invention.

In figure 1, which represents a General view of the vertical exhibition showcases with cooled, made according to the invention, the item numbers 1-4 indicate the actual back wall of the exhibit showcase, part, forming a roof, the lower part of which forms a chamber, and a large number of vertically superimposed on each of the shelves, each shelf is designed to accommodate chilled or frozen food products. Shelves installed on the rear part of the exhibition showcase. Exhibit showcase provided with the installation for Oh is adenia 6, which is made in the form of a heat exchanger/evaporator and a number of fans 7 that are installed in the camera according to a variant, schematically presented in figures 1 and 2.

Fans create streams of cold air, such that symbolically indicated by arrows in figure 1 and shown in more detail in figure 2 according to known variants of execution. It is established that the cold air rises inside the rear wall 1 to the front part 9 of the roof 2, where it goes through the hole 10 so that it forms a curtain of cold air before 11 exhibit showcase, before food, which are indicated in the diagram position 14. The figure 2 shows also that part of the air is separated from the vertically rising stream for it was distributed on the shelves, moving over food, which are indicated in the diagram position 14 in figures 1 and 2, and reached a vertical curtain 11. At the bottom of exhibit showcases the veil of the cold air is drawn through the device 15, which again takes the air on the level of the upper edge of the front wall of the facade 16 camera 3 by fans 7.

Figure 2 represents the presence of the second curtain of air, which is indicated by the position 18 and is outside the veil, this veil is in front of the veil of ohla the established air 11. This veil consists of air ambient air that is drawn in the upper part of the exhibition showcases by means of the fan 20 and is pumped down into the narrow passage, in front of the exhibit showcase. Secondary curtain 18 is not cooled.

In figures 3-6 depict particular, the device 13, re-collecting the cooled air from the curtain 11. We now describe in more detail this device with reference to these figures.

As shown, particularly in figure 3, the device performing the re-draw cooling air contains mostly horizontal blinds 22, that is, these blinds, which are provided with holes 23, which are located essentially in a horizontal plane and is made in the form of two rows of slits located along the axis, and vertical blinds 24, which contain holes 25, which are located in a plane essentially vertical, and performed similarly in the two rows of slits. As shown in figure 2, the vertical distance re of the air intake 22 and horizontal re-air intake 24 create the need to split the veil of the air flows Fa and Fb.

According to an important variant of execution of the invention the device for re-draw cooling air contains between two blinds, i.e. between the horizontal sting and 22 and vertical blinds 24, the inclined surface 27, which is located at an angle of 45° relative to the horizontal and vertical planes. Due to this inclined surface 27 both Fa and Fb are quickly reunited for devices re-sampling in such a way that allows for rapid relaminarization.

According to the rational option of carrying out the invention the horizontal and vertical blinds are supported by a large number of support parts 28 which are evenly distributed along the longitudinal axis of the exhibit showcase.

Figure 5 shows a perspective view of such a support piece 28. We note that it contains the middle part 29 in the form of a plate facing towards the outside of the exhibit showcases and which is perpendicular to the longitudinal axis of the exhibit showcases and rear facing in the direction of the camera, the edge 30, which is bent and forms an arc and has the shape of a curve, which is well visible in figure 4. The front edge of the middle part 29 contains portions that protrude in the vertical and horizontal lines 31, 32 which form the basic part of the plates 34 and 35 of the horizontal and vertical blinds.

Between the two support parts 31 and 32 which are vertically and horizontally outward, is provided intermediate portion 37 in the form of a beam, which is home the lateral direction on one side from the intermediate part 29, in the direction along the axis of the exhibit showcases and has a cross section essentially in the form of an inverted letter U. this part 37, which serves as a support for profile 39, front free outer side of which forms an inclined prevent stratification of the surface 27, is installed between the two re-fences of the air, i.e. between the horizontal re-air intake and vertical re-sampling air from the curtain of cooled air. As shown in figure 4, the profile contains 39 protruding in the direction toward the rear two ribs 40, which engages behind the branches 41 of the bar or support bar 37 in position when the profile is installed between the two horizontal and vertical device. It should also be noted that at the level of the upper and lower longitudinal edges of the profile 39 is curved protrusions 51, which provide the ability to set labels (not illustrated).

Bearing 28 includes a part forming a rack 42, which provides the ability to attach it to the front wall 16 of the camera. This part, forming a rack 42, stands sideways to one side relative to the middle part of the support and has in cross section the shape of the letter L, long branch 43 which is adjacent and attached to the inner side of the anterior chamber, while the other leg 44 is based is and the upper side, essentially on a horizontal wall of the chamber. The end of the branch 44 is bent to position 45 in such a way that it forms a foot for securing the support 28 on the front wall of the chamber by screws 46, the hole for the passage of screws indicated by the position 47 in figure 5.

On the support piece 28 on its end which is opposite the rack 42, we have installed a horizontal bar 49 to support shelves or plates 4 exhibit showcases by means of an intermediate profile 50, which is located along the entire length of the exhibition showcase and forms a lateral limiting wall horizontal blinds re-air intake. The other side of the bounding wall louvers formed top edge 51 of the front profile 39, which prevents stratification. The lower part of the region 51 forms a lateral limiting surface vertical blinds re-air intake, which is limited on the other side of the second lower thin plate 35. Each of the thin plates is introduced into the slit made in the support.

It should be noted that performed such a special way to form the support parts 28, in particular, due to the use of a curved rear edge provides the ability to connect the threads immediately taken for a repeat threads so that you can re-create between the fence and the fan 7, the air flow in the form of Speer is whether, while fans 7 are guided accordingly.

Figure 6 depicts another embodiment of a device for combined air intake, designed to be used for exhibition Windows on the front wall of the chamber which is installed facade additional element 57. In this case, the support piece blinds horizontal and vertical air intake, which is indicated by the position 28', identical parts 28, in its bearing halves, strictly speaking, blinds, but executed in a different way, in his the bottom of the bracket to the camera. Now this part contains, in its front part, a flange in the form of the letter Z, which contains the upper part 59 of the attachment of the front wall 57 of the tie, which is one part in the form L 60, the corresponding part of the frame, an L-shaped 42 of the support part 28 and which provides the ability to perform fastening to the front wall of the chamber.

In its part located exactly above the support part of the blinds re-horizontal fence rear edge facing the inside of the camera supporting parts 28', made in the form of a flange 61, which is located essentially vertically and provides the ability to set the vertical plate 62, which is located along the entire length of the exhibition showcase and sets for horizontal and vertical re-fences the air pipe 64. Plate 62 limits in the direction of the fences after air flows from the guide pipe 64, which provides the reunion re-taken flow, directs this newly reunited flow toward the rear edge of the output 68 of the support piece, which is made as well as the rear edge 30 of the support piece 28, in order to establish air flow in the form of a spiral between the device 15, re-taking the air, and a fan 7.

From the above description it follows that by applying this configuration, the supporting parts, according to which is provided by the forward inclined side and the rear edge, made in a special way, the invention provides the ability to re-combined air intake, that is, at the same time the horizontal fence and the vertical fence, which reduces the width of the exhibit showcase, while providing excellent cooling capacity. Of course, it is possible to make various modifications to the exhibit showcase, one that was described and represented in the figures, without leaving the scope of the invention, therefore, reference details of horizontal and vertical blinds can have any other appropriate shape provided that they meet the above two requirements, i.e. to ensure a minimum try is between the two fences and reunification and relaminarization air flows from intake immediately after two fences and restore the circulation of air flow in the form of a spiral between the fence and fans, performing a re-circulation flow of air in the upper part of the exhibition showcase, which passes through a refrigeration unit 6.

It should be noted that in addition to the just described functions of the parts 28 and 28' provide another additional feature, which is that they should provide the perception of effort shelves or plates, which are exposed food products, and the transfer of these efforts the camera.
