INSTALACIÓN ACONDICIONADORA TÉRMICA PARA MUEBLES CONTENEDORES DE ARTÍCULOS ALIMENTICIOS THERMAL CONDITIONING INSTALLATION FOR FURNITURE CONTAINERS OF FOOD ITEMS
D E S C R I P C I Ó ND E S C R I P C I Ó N
La presente invención se refiere a una instalación acondicionadora térmica para muebles contenedores de artículos alimenticios, en especial vitrinas y muebles para la conservación y la exposición de comestibles y bebidas en establecimientos de restauración, en colectividades, etc., que pueden ser de acceso libre o de venta automática con monedero o tarjeta y que comprenden una pluralidad de departamentos independientes que deben hallarse a diferentes temperaturas, que son constantes para cada uno de ellos.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.
Son conocidas las vitrinas y armarios que constituyen muebles para conservar artículos alimenticios a una sola temperatura, tales como los empleados en pastelerías y restaurantes para conservar helados, postres fríos, licores, copas y jarras de vidrio, etc. También son conocidas las neveras domésticas en las que una parte actúa como frigorífico, a una temperatura de unos 5°C, y otra parte lo hace como congelador a -18°C.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. Also known are 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.
En la mayoría de los casos, estos aparatos disponen de un solo grupo frigorígeno y en otros disponen de dos, uno para el frigorífico, y el otro para el congelador, pudiendo utilizar sistemas de frío por aire, (sin escarcha o "no frost") o de frío estático.In most cases, 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.
Acontece en la actualidad que, en muchos casos, interesa mantener unos artículos a una muy baja temperatura, como los helados, otros a una temperatura baja, como bocadillos, tapas, platillos cocinados, etc. y otros a temperatura media, tal como los refrescos, las cervezas, las aguas, los vinos blancos y rosados, los cavas, etc., para lo cual son necesarios tres muebles, a saber, respectivamente, un congelador, un frigorífico o vitrina y un botellero. Por otra parte, dichos muebles disponen su grupo frigorígeno solidario a su estructura, por lo que en caso de avería grave, es preciso transportar el mueble al taller, con el consiguiente engorro, coste y falta de servicio para el usuario.It is currently happening that, in many cases, it is interesting to keep some items at a very low temperature, such as ice cream, others at a low temperature, such as snacks, tapas, cooked dishes, etc. and others at medium temperature, such as soft drinks, beers, waters, white and rosé wines, cavas, etc., for which three pieces of furniture are needed, namely, a freezer, a refrigerator or a showcase and A bottle rack On the other hand, said furniture has its refrigeration group in solidarity with its structure, so that in case of serious breakdown, it is necessary to transport the furniture to the workshop, with the consequent nuisance, cost and lack of service for the user.
Con el fin de disponer de un mueble que sea capaz de mantener separadamente varias zonas de temperatura distintas se han ideado aparatos, como el descrito en la patente FR 1.235.373, que consiste en un aparador abierto para supermercado que dispone de tres niveles de frío, que incorpora un evaporador en cada una de las dos zonas inferiores, circulando el aire frío por gravedad entre las dos inferiores y por aspiración de la central a la superior, que se halla cerrada por una puerta practicable. En este caso, las zonas de frío están abiertas, solo existe una corriente de aire forzado entre las dos zonas superiores que lo es por aspiración y unidireccional y el grupo frigorígeno es fijo y dispone de un evaporador en cada una de las zonas en la que existe mayor pérdida de frío.In order to have a piece of furniture that is capable of maintaining several different temperature zones separately, devices have been devised, such as the one described in patent FR 1,235,373, which consists of an open sideboard for supermarkets that has three cold levels , which incorporates an evaporator in each of the two lower zones, the cold air circulating by gravity between the two lower ones and by aspiration from the central to the upper one, which is closed by a practicable door. In this case, the cold zones are open, there is only a forced air flow between the two upper zones that is by aspiration and unidirectional and the refrigeration group is fixed and has an evaporator in each of the areas in which There is greater loss of cold.
También es conocido el aparato de venta automática descrito en la patente EP 1.076.213, en el que se dispone una columna giratoria de pisos compartimentados y abiertos, contenedores de los artículos a expender, que están atravesados centralmente por una conducción de aire frío que penetra radialmente entre cada dos pisos a través de válvulas de paso regulable, con lo que cada piso recibe más o menos aire frío en función de las características del artículo a conservar y a expender a través de portezuelas deslizantes, habiéndose previsto el crear dos zonas de pisos a diferente temperatura, separadas por una envolvente, de las cuales una sola recibe aire frío y la otra resta a temperatura ambiente. En este caso existe una corriente forzada de aire frío en la fase de impulsión y un retorno alrededor de los pisos, disponiendo de un solo grupo frigorígeno fijo. A la vista de cuanto antecede, sería de desear un mueble que pudiese disponer de dos o más zonas, independientes y cerradas, con otros tantos niveles de temperatura, que estas fueren programables y que el equipo frigorígeno fuera fácilmente substituible en caso de avería sin necesidad de su traslado al taller.Also known is the automatic sales apparatus described in EP 1,076,213, in which there is a rotating column of compartmentalized and open floors, containers of the items to be dispensed, which are traversed centrally by a penetrating cold air duct. radially between every two floors through valves of adjustable passage, with which each floor receives more or less cold air depending on the characteristics of the article to be conserved and distributed through sliding doors, having planned to create two areas of floors to different temperature, separated by an envelope, of which one receives cold air and the other subtracts at room temperature. In this case there is a forced flow of cold air in the discharge phase and a return around the floors, having only one fixed refrigeration group. In view of the foregoing, it would be desirable to have a piece of furniture that could have two or more zones, independent and closed, with as many temperature levels, that these were programmable and that the refrigeration equipment be easily replaceable in case of failure without need of his transfer to the workshop.
De acuerdo con las precedentes premisas se ha desarrollado la instalación acondicionadora térmica para muebles contenedores de artículos alimenticios objeto de la invención, la cual incluye un único grupo frigorígeno que crea una corriente de aire que se desplaza, forzada por un ventilador impulsor, dentro de un circuito cerrado formado por un conducto de ida que enlaza con otro conducto e retorno y éste, a su vez, enlaza con el conducto de ida a través de una cámara de impulsión, en la que se encuentra el citado ventilador impulsor, encarado a la boca de impulsión del conducto de ¡da, y un evaporador, encarado a la boca de llegada del conducto de retorno, abriéndose a lo largo del conducto de ida de la corriente de aire frío una serie de ventanas de comunicación de otros tantos departamentos con la citada corriente de aire frío, las cuales están controladas mediante trampillas independientes de cierre, actuadas termostáticamente, que, abiertas, permiten la entrada de dicho aire frío en el departamento correspondiente y la salida del aire menos frío contenido en el mismo y que se cierran al alcanzar dicho departamento la temperatura prevista, estando el grupo frigorigeno constituido por un módulo extraible del mueble que incluye el evaporador y el ventilador impulsor del circuito de aire.In accordance with the previous premises, the thermal conditioning installation for furniture containers of food items object of the invention has been developed, which 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.
Una característica de la invención consiste en el hecho de que el grupo frigorígeno, que comprende esencialmente un motocompresor eléctrico, un condensador con su ventilador, un evaporador y el ventilador impulsor, está montado sobre un soporte desplazable que constituye una parte del módulo extraible del mueble.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 .

Según una realización preferente de la invención las trampillas independientes están constituidas por placas conformadas de modo que, siendo giratorias alrededor de un eje medio que es transversal al sentido de la corriente de aire frío en el conducto de ida, presentan dos zonas marginales paralelas a dicho eje y dobladas en sentidos contrarios de modo que, en el cierre, se asientan sobre zonas opuestas de la abertura de las ventanas obturando a las mismas y, en la apertura, constituyen deflectores conductores de las corrientes de aire entrantes y salientes del departamento. Estas trampillas, que son independientes, están motorizadas y gobernadas en función de un termostato. Otra característica de la invención comprende el hecho de que el soporte desplazable, que constituye una parte del módulo extraible, comprende medios de acoplamiento estanco al circuito de aire frío y de conexión automática a la red de suministro eléctrico. Finalmente, otra característica más de la invención la constituye el hecho de que la cámara de impulsión está delimitada por una bandeja colectora del agua de condensación, el ventilador de impulsión, el evaporador y una pared de fondo del mueble, siendo los tres primeros solidarios del soporte desplazable del módulo extraible. Para facilitar la comprensión de las ideas precedentes, se describe seguidamente una realización preferida de la invención, haciendo referencia a los dibujos ilustrativos que la acompañan. En los dibujos:According to a preferred embodiment of the invention, 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. Finally, another characteristic of the invention is the fact that the discharge chamber is delimited by a collecting tray of the condensation water, the discharge fan, the evaporator and a bottom wall of the furniture, the first three being integral with the removable removable module holder. To facilitate the understanding of the preceding ideas, a preferred embodiment of the invention is described below, with reference to the accompanying illustrative drawings. In the drawings:
Figura 1 , representa, esquemáticamente, un mueble vertical que comprende tres departamentos sobrepuestos, a acondicionar térmicamente, que disponen de otras tantas puertas de acceso y están, asimismo, relacionados controladamente con un circuito cerrado de aire frío generado por un grupo frigorígeno, todo ello de acuerdo con la invención.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.
Figura 2, representa, análogamente, el mueble de la figura anterior, mostrando la especial disposición del grupo frigorígeno en forma de módulo extraible.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.
En la figura 1 se muestra un mueble 1 , en este caso vertical aunque también podría ser horizontal, que comprende tres departamentos 2A, 2B y 2C, accesibles independientemente desde el exterior a través de las puertas practicables 3, que están destinados a contener diferentes artículos alimenticios a su temperatura de conservación y de consumo. Así, por ejemplo, el departamento inferior 2A estaría a 6°C, el intermedio 2B a 12°C y el superior 2C a 14°C.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. Thus, for example, the lower department 2A would be at 6 ° C, intermediate 2B at 12 ° C and the upper one 2C at 14 ° C.
Estos departamentos 2A, 2B y 2C, en oposición a sus puertas practicables 3, disponen cada uno de ellos de una ventana 4 cerrada por una trampilla 5 que es giratoria alrededor de un eje medio 6 mediante un dispositivo motor gobernado termostáticamente, que no ha sido representado por ser convencional.These departments 2A, 2B and 2C, as opposed to their practicable doors 3, each have a window 4 closed by a trapdoor 5 which is rotatable about a middle axis 6 by means of a thermostatically controlled motor device, which has not been represented by being conventional.
Tales trampillas 5, siendo independientes entre sí, están situadas en una pared de un conducto de ida 7A que, complementado con un conducto de retorno 7B, constituyen un circuito cerrado de aire frío en el que se incluyen una cámara de enlace 8 y una cámara de impulsión 9.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.
