Definitions

  • the present invention relates to a thermal conditioning installation for furniture containers of food items, especially showcases and furniture for the conservation and exhibition of food and beverages in catering establishments, in communities, etc., which can be freely accessible or automatic sale with purse or card and comprising a plurality of independent departments that must be at different temperatures, which are constant for each of them.
  • Showcases and cabinets that constitute furniture to preserve food items at a single temperature such as those used in patisseries and restaurants to store ice cream, cold desserts, spirits, glasses and glass jars, etc., are known.
  • domestic refrigerators in which one part acts as a refrigerator, at a temperature of about 5 ° C, and another part does it as a freezer at -18 ° C.
  • these devices have a single refrigeration unit and in others they have two, one for the refrigerator, and the other for the freezer, being able to use air-cold systems, (without frost or "no frost” ) or static cold.
  • the thermal conditioning installation for furniture containers of food items object of the invention includes a single refrigerating group that creates a current of air that is displaced, forced by a driving fan, within a closed circuit formed by a one-way conduit that links with another return conduit and this, in turn, links with the outflow duct through an impulse chamber, in which said impeller fan is located, facing the impeller duct of the da duct, and an evaporator, facing the mouth of arrival of the return duct, a series of communication windows of as many departments with the said cold air stream being opened along the outgoing duct of the cold air stream, which are controlled by independent closing flaps, actuated thermostatically, that, open, allow the entry of said cold air into the corresponding department and the exit of the less cold air contained therein and that close when said department reaches the expected temperature, the refrigeration group being constituted by a removable module of the cabinet that includes the evaporator and the air circuit drive fan.
  • a feature of the invention consists in the fact that the refrigerating group, which essentially comprises an electric motor compressor, a condenser with its fan, an evaporator and the impeller fan, is mounted on a movable support which constitutes a part of the removable furniture module .
  • the refrigerating group which is an absorption cycle and essentially comprises an absorber, a generator, a pump arrangement, a heat exchanger, a reduction valve , a condenser with its fan, an evaporator and the impeller fan, is mounted on a movable support that constitutes a part of the removable furniture module.
  • the independent flaps are constituted by plates formed so that, being rotatable about a mid-axis that is transverse to the direction of the cold air current in the flow passage, they have two marginal zones parallel to said axis and bent in opposite directions so that, in the closure, they sit on opposite areas of the opening of the windows sealing them and, in the opening, they constitute conductive deflectors of the incoming and outgoing air currents of the department.
  • These hatches, which are independent, are motorized and governed according to a thermostat.
  • Another feature of the invention comprises the fact that the movable support, which constitutes a part of the removable module, comprises means of tight coupling to the cold air circuit and automatic connection to the power supply network.
  • Figure 1 represents, schematically, a vertical piece of furniture that comprises three superimposed departments, to be thermally conditioned, which have as many access doors and are also related in a controlled way with a closed circuit of cold air generated by a refrigerating group, all this according to the invention.
  • Figure 2 similarly, represents the furniture of the previous figure, showing the special arrangement of the refrigerating group in the form of a removable module.
  • Figure 1 shows a piece of furniture 1, in this case vertical although it could also be horizontal, comprising three departments 2A, 2B and 2C, independently accessible from the outside through the practicable doors 3, which are intended to contain different items food at its temperature of conservation and consumption.
  • the lower department 2A would be at 6 ° C, intermediate 2B at 12 ° C and the upper one 2C at 14 ° C.
  • Such hatches 5 being independent of each other, are located in a wall of a passage duct 7A which, complemented with a return duct 7B, constitute a closed cold air circuit in which a link chamber 8 and a discharge chamber 9 are included.
  • the aforementioned independent hatches 5 are constituted by plates formed so that, being rotatable about said middle axis 6 which is disposed transverse to the direction of the cold air current in the passage duct 7A, they have two marginal zones 10 parallel to said middle axis 6 and folded in opposite directions so that, in the closure, they sit on opposite areas of the opening of the windows 4, as seen in the flaps 5 of the departments 2A and 2B of the figures, sealing the said openings, while, in the opening, they constitute conductive deflectors of the incoming cold air stream (lower arrow) and the less cold outgoing air (upper arrow).
  • the refrigerating unit which in the case of compression cycle conventionally comprises essentially an electric motor compressor 11, a condenser 12 with its fan 13, an evaporator 14 and a drive fan 15, is mounted on a movable support 16, whether by wheels 17, be it by means of skates, guides or others, which constitutes a part of the removable module of the furniture 1.
  • a movable support such as an absorption cycle, it is necessary to apply a movable support equivalent to that described.
  • the movable support 16 comprises sealed coupling means 18 and 19 to the cold air circuit and forms part of the discharge chamber 9 by means of a tray 20 collecting the condensation water of the air, the discharge fan 15, the evaporator 14 and a wall 21 of the bottom of the furniture 1.
  • the movable support 16 has automatic electrical connection means to a connection base installed in the furniture 1 and connected to the power supply network.
  • the housing 22 in the furniture 1 for the refrigerating unit mounted on the sliding support 16 is closed, practically by a grid 23.

Abstract

Cette installation comprend une seule unité frigorifique qui créé un courant d'air à l'intérieur d'un circuit fermé pourvu d'un conduit de sortie connecté à un conduit d'entrée qui, lui, est connecté au conduit de sortie par une chambre d'impulsion comprenant un ventilateur d'impulsion et un évaporateur. Une série de fenêtres de communication d'autres compartiments avec ledit courant d'air froid s'ouvrent le long du conduit de sortie du courant d'air froid, ces fenêtres étant régulées au moyen d'ouvertures thermostatiques. L'unité frigorifique est constituée d'un module pouvant être extrait du meuble qui comprend l'évaporateur et le ventilateur d'impulsion du circuit d'air.
