Description

Armario refrigerador con compartimentos de almacenaje de alimentos separados.Refrigerator cabinet with compartments separate food storage.

Campo y antecedentes de la invenciónField and background of the invention

La presente invención se refiere a un armario refrigerador según el preámbulo de la reivindicación 1. Tal armario refrigerador se describe en la GB-A-2047863.The present invention relates to a closet refrigerator according to the preamble of claim 1. Such a cabinet refrigerator is described in the GB-A-2047863.

Los armarios refrigeradores cuyo espacio interno está subdividido en dos o más compartimentos en los que se generan diferentes temperaturas adecuadas para el almacenamiento y la conservación de tipos particulares de alimentos, se conocen bien en el arte. Normalmente, estos armarios refrigeradores están provistos de circuitos de refrigeración separados que están dimensionados y diseñados para asegurar el mantenimiento, en el espacio o compartimento de almacenaje correspondiente, de la temperatura necesaria para los alimentos allí almacenados.Refrigerating cabinets whose internal space is subdivided into two or more compartments in which they are generated different temperatures suitable for storage and conservation of particular types of food, are well known in the art. Normally, these refrigerator cabinets are provided of separate cooling circuits that are sized and designed to ensure maintenance, in space or corresponding storage compartment, temperature necessary for the food stored there.

También se conocen muy bien en el arte armarios refrigeradores que, aunque presentan más de un espacio de almacenamiento, sólo están provistos de un único circuito de refrigeración que se controla mediante diferentes sondas de termostato dispuestas en cada uno de dichos espacios de almacenaje. En este caso, la circulación del medio refrigerante es guiada, desviada y/o suprimida mediante válvulas adecuadas para asegurar el efecto de refrigeración correcto en los diferentes espacios de almacenaje según las condiciones de temperatura correspondientes que se necesiten dentro.Closets are also very well known in art refrigerators that, although they have more than one space of storage, they are only provided with a single circuit of cooling that is controlled by different probes of thermostat arranged in each of said storage spaces. In this case, the circulation of the cooling medium is guided, diverted and / or suppressed by appropriate valves to ensure the correct cooling effect in the different spaces of storage according to the corresponding temperature conditions that are needed inside.

Sin embargo, tales armarios refrigeradores del estado de la técnica no pueden resolver el problema al que hay que enfrentarse siempre que se necesita almacenar y conservar, sustancialmente a la misma temperatura, alimentos que son diferentes en lo que se refiere a sus características organolépticas peculiares. En particular, este problema se encuentra cuando tienen que almacenarse en el mismo compartimento o espacio, alimentos tales como carne, queso, verduras y similares, que, como se sabe, despiden olores peculiares que se pueden mezclar entre sí, con el resultado de que se alteran sus sabores y aromas, a menudo hasta límites bastante inaceptables.However, such refrigeration cabinets of the state of the art cannot solve the problem to which face whenever storage and preservation is needed, substantially at the same temperature, foods that are different in regard to its organoleptic characteristics peculiar. In particular, this problem is encountered when they have to be stored in the same compartment or space, such foods like meat, cheese, vegetables and the like, which, as you know, say goodbye peculiar odors that can be mixed with each other, with the result that their flavors and aromas are altered, often up to limits quite unacceptable.

La solución que requiere la utilización de armarios refrigeradores provistos de una pluralidad de espacios de almacenamiento separados, en los que cada uno de ellos se enfría mediante un circuito de refrigeración propio, no se propone debido a razones económicas y a la complejidad técnica que ello implicaría de manera inevitable, teniendo en cuenta al mismo tiempo el hecho de que es prácticamente la misma temperatura la que se tiene que mantener en los diferentes compartimentos.The solution that requires the use of refrigerator cabinets provided with a plurality of spaces separate storage, in which each of them cools through its own cooling circuit, it is not proposed due to economic reasons and the technical complexity that this would imply from inevitable way, while taking into account the fact which is practically the same temperature which has to be Keep in different compartments.

Breve descripción de la invenciónBrief Description of the Invention

Por tanto un propósito principal de la presente invención es proporcionar un armario refrigerador provisto de al menos dos espacios de almacenamiento separados, en cada uno de los cuales está dispuesto un evaporador que forma parte de un único y el mismo circuito de refrigeración adaptado para generar y mantener sustancialmente la misma temperatura en todos los mencionados espacios 

\hbox{de almacenamiento.}
Therefore, a main purpose of the present invention is to provide a refrigerator cabinet provided with at least two separate storage spaces, in each of which an evaporator that is part of a single and the same cooling circuit adapted to generate and generate maintain substantially the same temperature in all the mentioned spaces 
 \ hbox {storage.}

Las características de la presente invención se definen en la reivindicación 1.The characteristics of the present invention are defined in claim 1.

Breve descripción del dibujoBrief description of the drawing

En cualquier caso, las características y ventajas de la presente invención se entienden con más facilidad en la descripción que se da a continuación a modo de ejemplo no limitativo con referencia al dibujo que se adjunta, que es una vista en perspectiva esquemática de un armario refrigerador según la presente invención, con sus puertas abiertas por completo, y en donde se muestra por separado un detalle a mayor escala del citado armario refrigerador.In any case, the characteristics and advantages of the present invention are more readily understood in the description given below by way of non-limiting example with reference to the drawing attached, which is a view in schematic perspective of a refrigerator cabinet according to the present invention, with its doors open completely, and where show separately a larger scale detail of the aforementioned closet fridge.

Descripción detallada de la invenciónDetailed description of the invention

El armario refrigerador según la presente invención está normalmente formado por una caja externa 10 provista de dos compartimentos o espacios de almacenaje internos 11, 12 que están completamente separados uno de otro y se pueden cerrar mediante puertas correspondientes 13, 14. Dentro de dichos espacios de almacenaje se pueden insertar, de un modo por si conocido que no se ilustra en la figura, estantes o rejillas para soportar los diferentes alimentos que están en el interior, los cuales, aunque difieren entre si en lo que se refiere a su naturaleza, necesitan de todos modos permanecer almacenados a temperaturas sustancialmente similares.The refrigerator cabinet according to the present invention is normally formed by an external box 10 provided of two internal compartments or storage spaces 11, 12 that they are completely separated from each other and can be closed through corresponding doors 13, 14. Within these spaces of storage can be inserted, in a way known per se than not illustrated in the figure, shelves or grilles to support the different foods that are inside, which, although they differ from each other in regards to their nature, they need to anyway remain stored at substantially temperatures Similar.

En cada uno de tales espacios de almacenaje 11, 12 está provista una batería de evaporador asistida por ventilador 15, 16, baterías de evaporador que están normalmente conectadas en serie a un circuito refrigerador que comprende un compresor 17 y un condensador 18. De un modo ventajoso, como el que se ilustra en la figura, las partes componentes del circuito de refrigeración están alojadas en la parte superior del armario.In each of such storage spaces 11, 12 a fan-assisted evaporator battery is provided 15, 16, evaporator batteries that are normally connected in series to a cooling circuit comprising a compressor 17 and a capacitor 18. In an advantageous manner, as illustrated in the figure, the component parts of the cooling circuit are housed in the upper part of the closet.

Según la presente invención, los espacios de almacenaje 11, 12 están separados por una pared divisoria 20 que está situada dentro de la caja externa 10. Esta pared divisoria se hace para permitir un máximo grado de intercambio calorífero entre los dos espacios de almacenaje, pero no una mezcla de las corrientes de aire frío que circulan por dichos espacios de almacenaje. En otras palabras, la pared divisoria 20 constituye un cierre hermético entre los dos espacios de almacenaje.According to the present invention, the spaces of storage 11, 12 are separated by a dividing wall 20 that it is located inside the outer box 10. This dividing wall is does to allow a maximum degree of heat exchange between the two storage spaces, but not a mixture of streams of cold air circulating through these storage spaces. In in other words, partition wall 20 constitutes a seal between the two storage spaces.

La pared divisoria 20 se hace preferiblemente con forma de lámina u hoja metálica muy delgada y, por tanto, de un material con una alta conductividad térmica. De este modo se consigue muy rápidamente el equilibrio deseado de las temperaturas en los espacios de almacenaje separados, también cuando solamente se enfría uno de ellos debido a las necesidades de funcionamiento, por ejemplo cuando se introduce una nueva carga de alimentos a enfriar en su
interior.The dividing wall 20 is preferably made in the form of a very thin sheet or metal sheet and, therefore, of a material with a high thermal conductivity. In this way, the desired equilibrium of temperatures in the separate storage spaces is achieved very quickly, also when only one of them cools due to operational needs, for example when a new load of food to be cooled is introduced into its
inside.

De nuevo según la presente invención, se proporciona una sonda de termostato 21 para controlar el funcionamiento del circuito de refrigeración. Esta sonda 21 tiene que ser capaz de detectar la temperatura de ambos espacios de almacenaje 11, 12 y, por tanto, está instalada en la pared divisoria 20. Por razones de mayor simplicidad en la construcción y fabricación, la sonda 21 (como se ilustra esquemáticamente en la parte a mayor escala, y que se ve en vista lateral y vista en sección) está dispuesta en una abertura provista en la pared 20 y está cerrada herméticamente entre dos piezas moldeadas que están unidas a las superficies opuestas de la misma pared. Estas piezas moldeadas pueden unirse en cualquiera de los diferentes modos conocidos, por ejemplo mediante adhesivo o soldadura. De este modo, la sonda 21 detecta normalmente una temperatura que es la temperatura media de las temperaturas que predominan en los espacios de almacenaje 11, 12. Además, la sonda detecta inmediatamente cualquier posible variación repentina de temperatura en cualquiera de los dos espacios de almacenaje 11, 12, y por tanto puede activar, es decir, hacer que comience, el funcionamiento del circuito de refrigeración.Again according to the present invention, provides a thermostat probe 21 to control the Cooling circuit operation. This probe 21 has to be able to detect the temperature of both spaces of storage 11, 12 and, therefore, is installed in the partition wall 20. For reasons of simplicity in construction and manufacturing, probe 21 (as schematically illustrated in the part on a larger scale, and that is seen in side view and seen in section) is arranged in an opening provided in the wall 20 and it is tightly closed between two molded parts that are attached to opposite surfaces of the same wall. These pieces molded can be joined in any of the different modes known, for example by adhesive or welding. In this way, probe 21 normally detects a temperature that is the average temperature of the temperatures prevailing in the spaces storage 11, 12. In addition, the probe immediately detects any possible sudden temperature variation in any of the two storage spaces 11, 12, and therefore can activate, that is, make it begin, the operation of cooling circuit

La sonda 21 está, naturalmente, conectada al compresor 17 del circuito de refrigeración vía un circuito electrónico de tipo normalmente conocido, que, por tanto, no se va a describir aquí con más detalle, y el cual permite que se pueda fijar y controlar apropiadamente la temperatura a mantener en los espacios de almacenaje del armario refrigerador.The probe 21 is naturally connected to the compressor 17 of the refrigeration circuit via a circuit electronic type normally known, which, therefore, is not going to describe here in more detail, and which allows it to be fixed and properly control the temperature to be maintained in the spaces of storage of the refrigerator cabinet.

Se puede, por tanto, apreciar fácilmente que la solución propuesta según la presente invención es particularmente simple y adecuada. De hecho, permite proporcionar a un armario refrigerador un único circuito de refrigeración y al menos dos espacios de almacenaje separados, en los que se pueden almacenar alimentos que, aunque necesitan temperaturas de almacenaje sustancialmente iguales, no se pueden mantener juntos en el mismo espacio o compartimiento debido a su naturaleza organoléptica.It can therefore be easily appreciated that the proposed solution according to the present invention is particularly Simple and adequate. In fact, it allows to provide a closet refrigerator a single refrigeration circuit and at least two separate storage spaces, in which they can be stored foods that, although they need storage temperatures substantially the same, they cannot be kept together in it space or compartment due to its organoleptic nature.
