Definitions
- the present invention refers to a refrigerated display cabinet for ice creams, pastry products and the like, which consists of a cabinet cooled by a refrigerating system that allows these products to be stored and displayed within prescribed temperature limits.
- this known display (1) usually comprises:
- the aforementioned conventional refrigerated displays (1) for ice cream or pastes which use the principle of static refrigeration, in which the low-temperature air is stratified lower, touching the top of the food after it has fallen from the evaporator (4), so that the evaporator (4) is always above the food (3), contain the food in the insulated body (2) about 150 mm below its edge; this ensures that the food is stored at the prescribed temperature, but reduces the visibility, and thus the viewing capacity, of the cabinet, especially if approached from a distance of a few meters.
- EP 3 933 315 A1 is another refrigerated display cabinet known in the art.
- the main object of the invention is providing a refrigerated display cabinet that improves the visibility of the food, allows significant energy savings (by doing without a heated glass) and allows to consequently reduce its final production cost.
- the refrigerated display cabinet (1) of the invention achieves the intended purposes by providing to lower the insulating body (2) on its front part and/or on the sides of the refrigerating display cabinet (1) in which the food is cooled by convection static, using:
- the heating cabinet display (1) may further comprise at least one heating element, not shown and preferably of the resistance type, designed to heat the gap between the secondary barrier (5) and the main containment barrier (9) in order to prevent a fogging of the upper transparent structure (5).
- the deflector (8) is designed to cooperate with the evaporator (4) so as to allow the passage of air in a closed loop above the deflector (8) and towards the containers (3).
- This passage can be achieved by providing that the deflector (8) allows warmer air to enter from the top and cooled air to escape from the lower part (4), so as to obtain two horizontal spaces, one above, the other below the deflector (8) itself for the passage of air.
- the deflector (8) could be equipped with at least one opening (not shown), and preferably a series of openings, for the passage of air, each of these openings being placed along its surface on the long side of the deflector (8).
- the refrigerated display cabinet (1) described above conveys the colder air coming from the evaporator (4) right above the food, and the cold air, pushed by the new air coming from the evaporator (4), moves forward, on a plane that is parallel to the food, until it meets the main barrier (9).
- air is heated by an external heat flow due to the temperature difference between internal and external air of the refrigerated display cabinet (1), which is at ambient temperatures, in a typical temperature range of 20 °C - 35 °C.
- This heat flow heats cold air in the refrigerated display cabinet (1), which is between the deflector (8) and the main barrier (9), which can be understood as a containment basin.
- This air as it heats up, increases its static pressure decreasing in density, lighter than the cold air, and rises and moves back towards the evaporator (4) to compensate for the air moving downwards, once cooled by the evaporator (4).
- the refrigerated display cabinet (1) is therefore designed so that the main barrier (9) prevents cold air from overflowing from the basin and directly cools the secondary barrier (5) and the deflector (8), which is designed so that the further supply of cold air from the evaporator (4) falls downwards towards the food, and allows the warmer air that is being raised to access the evaporator (4) from above.
- the refrigerated display cabinet (1) is then completed by the secondary barrier (5) which creates an intermediate layer of air at a warmer temperature than the air in the cold basin, but at a lower temperature than the outside air, and avoids that the air flow from the external environment interrupts the static cooling ring (10) which creates the barrier-deflector system.
- the static refrigerant ring provides cold air that cools the food and a recirculation of air that prevents the warmer air coming from the external environment through the opening cover (6) from condensing on the cold internal surfaces of the display cabinet (1).

Claims (6)
- Vitrine réfrigérée (1) comprenant:- un corps isolé (2);- une structure pour supporter des récipients (3) qui contiennent les aliments conservés, la structure étant contenue à l'intérieur du corps isolé (2);- un évaporateur (4) contenu dans le corps isotherme (2), placé à côté des conteneurs (3) et conçu pour fonctionner par convection naturelle, où le fluide réfrigérant secondaire est de l'air;- un motocompresseur et un groupe de condensation contenus dans une partie non isolée du corps isolé (2) et qui utilisent un fluide réfrigérant primaire, tel que le R290;- une structure supérieure transparente (5), typiquement en verre, placée au-dessus du corps isotherme (2) et équipée d'un système de fermeture (6) pour permettre l'accès aux aliments à servir ou pour fermer le compartiment réfrigéré lorsqu'il ne l'est pas utilisé;- un déflecteur d'air (8) situé à proximité de l'évaporateur (4) et entre l'évaporateur (4) et les conteneurs (3);- une barrière de confinement principale (9), de préférence transparente et périmétrique, placée autour de trois côtés des conteneurs (3); et- une barrière secondaire (5), constituée de la structure supérieure transparente (5) non chauffée et destinée à créer une cavité avec la barrière de confinement principale (9),caractérisé par le fait qu'il comprend également au moins un élément chauffant destiné à chauffer l'espace entre la barrière secondaire (5) et la barrière de confinement principale (9) afin d'éviter la formation de buée sur la structure supérieure transparente (5).
- Vitrine réfrigérée (1) selon la revendication 1, caractérisée en ce que le déflecteur (8) est conçu pour coopérer avec l'évaporateur (4) de manière à permettre le passage de l'air en boucle fermée au dessus du déflecteur (8) et vers les conteneurs (3).
- Vitrine réfrigérée (1) selon la revendication 2, caractérisée en ce que le déflecteur (8) est conçu pour permettre à l'air plus chaud d'entrer par la partie supérieure et à l'air refroidi de s'échapper de la partie inférieure (4), de manière à créer deux espaces horizontaux, l'un au-dessus, l'autre au-dessous du déflecteur (8) lui-même pour le passage de l'air.
- Vitrine réfrigérée (1) selon la revendication 1, 2 ou 3, caractérisée par le fait que le déflecteur (8) est équipé d'au moins une ouverture de passage d'air située le long de sa surface.
- Vitrine réfrigérée (1) selon la revendication 1, caractérisée en ce que ledit élément chauffant est du type à résistance.
- Vitrine réfrigérée (1) selon l'une quelconque des revendications précédentes, caractérisée en ce qu'elle comprend également un compartiment de réserve de stockage fermé (7) contenu dans le corps isotherme (2) et qui sert à contenir d'autres aliments non exposés.
