    [0002] Enclosure for cold stores.
    [0003]
    [0004] Object of the invention.
    [0005]
    [0006] The object of the present invention is an enclosure for cold rooms, suitable for closing a gap for access to a cold room and comprising: a sliding cold door, and a fast opening door that has a frame provided with vertical uprights, at least one flexible sheet exposed to the cold of the cold room and movable by guides of the vertical uprights; and a motorized drum, provided with a protective cover, for winding and unwinding said flexible sheet.
    [0007]
    [0008] This enclosure for cold rooms has constructive features aimed at preventing the formation of frost on the flexible sheet of the roller door exposed to the cold of the cold room; and eventually, additionally, to prevent the formation of ice or frost in the winding area of the flexible sheet located inside the protective cover.
    [0009]
    [0010] Field of application of the invention.
    [0011]
    [0012] This invention is applicable in the cold storage sector.
    [0013]
    [0014] State of the art
    [0015]
    [0016] Document ES 2 166 246 B1 of the same applicant describes a closing system for cold stores that includes a sliding door that is sliding and parallel to it, in the direction towards the inside of the chamber, a fast opening door designed to minimize losses of temperature while the outside refrigeration door remains open.
    [0017]
    [0018] In said background both the refrigerating or insulating door and the opening door They are located quickly on the outside of the access chamber to the cold store so that the flexible sheet of the quick opening door remains exposed to the cold inside the cold room but the motorized drum responsible for winding and unwinding said flexible sheet It is arranged on the outside of the chamber access hole.
    [0019]
    [0020] An additional drawback of this type of doors is the formation of frost on the flexible sheet of the quick-opening door that is exposed to the cold inside the cold room since this frost considerably increases the thickness of the sheet itself irregularly and irregularly. flexible and when wound on the motorized drum, during the opening operation of the door it forms a coil of excessive thickness that comes into contact with the protective cover of the motorized drum.
    [0021]
    [0022] In the event that the quick-opening door has two parallel flexible sheets, which form an insulating chamber with each other, there is a circumstance that the thickness of frost occurs only in one of the flexible sheets, specifically in the flexible sheet exposed to the cold of the cold store; causing that the movement of the two flexible sheets is not carried out in a coordinated way, which can cause malfunctions of the quick opening door.
    [0023]
    [0024] Although it is true that there are some antecedents of fast-opening doors with flexible sheets and that they incorporate means for the projection of air in the space between both flexible sheets, the proposed solutions are not particularly effective in the case of enclosures of cold rooms , as described above, since the projected air does not reach the entire surface of the flexible sheet uniformly, mainly due to the fact that the higher temperature air moves towards the upper area of the gap and does not prevent the formation of Frost on the bottom of that flexible sheet in contact with the low temperatures inside the cold store.
    [0025]
    [0026] The applicant is unaware of the existence of antecedents that satisfactorily solve the problem presented and that present characteristics similar to those of the present invention.
    [0027] Description of the invention
    [0028]
    [0029] The enclosure for cold rooms that is the object of this invention is suitable for closing a space for access to a cold room and, comprising a sliding cold door; and a quick opening door comprising: a frame provided with vertical uprights, at least one flexible sheet, exposed to the cold of the chamber, movable by guides of the vertical uprights; and a motorized drum, provided with a protective cover, for winding and unwinding said flexible sheet, as contemplated in the preamble of the main claim; It has some characteristics oriented to satisfactorily solve the problem described above and specifically, to avoid the formation of frost on the flexible sheet of the rapid opening door exposed to the cold of the chamber.
    [0030]
    [0031] For this purpose and in accordance with the invention, the vertical uprights of the quick opening door frame comprise: - on an outer face at least one mouth in which an air introduction fan is coupled to the corresponding vertical upright; - in its interior a deflector plate that directs the air supplied by the fan towards the lower area of the vertical upright, and below said deflector plate some electric resistors for heating the supplied air and, - on an inner face an outlet for the supply of hot air on one of the surfaces, inside or outside, of the flexible exposed to the cold of the chamber and the removal of frost from said flexible sheet.
    [0032]
    [0033] The arrangement inside the vertical uprights of the quick-opening door of the aforementioned reflector plate and, below it, the electric heaters responsible for heating the supplied air, in addition to simplifying its assembly, guarantee that the hot air go to the lower part of the quick-opening door by ascending the inner or outer surface of the flexible sheet of the quick-opening door exposed to cold, ensuring that no frost forms at any point on its surface.
    [0034]
    [0035] To ensure this objective, depending on the height of the door, it is provided that each of the vertical uprights of the quick-opening door frame can incorporate several groups of fans, reflectors, resistors and air vents hot arranged at different heights, ensuring that hot air affects both the upper zone, the intermediate zone and the lower zone of the flexible sheet.
    [0036]
    [0037] In one embodiment of the invention, the quick opening door incorporates inside the protective cover of the motorized drum, electric resistors that prevent the formation of ice or frost in said area.
    [0038]
    [0039] It should be mentioned that the hot air outlets can be arranged on one side or the other of the flexible sheet of the rapid opening door exposed to the cold of the cold room and that said rapid opening door can have a single flexible sheet, or two flexible sheets arranged in parallel and that are simultaneously wound or unwound in the motorized drum.
    [0040]
    [0041] In an alternative embodiment of the invention, the means for preventing the formation of frost on the flexible sheet of the quick-opening door facing the interior of the chamber are arranged superiorly and not on the vertical uprights of the frame.
    [0042]
    [0043] The features of the invention will be more readily understood in view of the exemplary embodiment shown in the accompanying figures described below.
    [0044]
    [0045] Description of the figures.

    [0049] - Figure 1 shows a schematic profile view of an embodiment example of the enclosure for cold rooms according to the invention in which the cold door and the quick opening door, in this case of flexible double sheet, are mounted on the side outside of the chamber access hole; the quick opening door and a portion of the chamber being sectioned in a vertical plane.
    [0050] - Figure 2 shows an elevational view of the enclosure of Figure 1 seen from inside the cold room and partially sectioned to allow observation of the hot air supply means towards the flexible sheet of the rapid opening door oriented towards the inside of the cold room.
    [0051]
    [0052] - Figure 3 shows a view similar to Figure 1 of a variant embodiment in which the quick opening door has a single flexible sheet and the hot air outlets project the air on the outer surface of the flexible sheet, is that is, on the surface facing outward of the chamber.
    [0053]
    [0054] - Figure 4 shows an alternative embodiment of the invention, in which the fans and air heating resistors are housed in a device located in the upper part of the access opening, and not in the vertical uprights of the frame, projecting hot air from the top towards the bottom area.
