Description

Multiple cooler of packaged liquids.

Object of the invention

The present invention relates to a cooler of all types of packaged liquids, although its commercial projection preferential is aimed at cooling drinks intended for consumption by the public in hospitality establishments. It allows the establishment to maintain a wide variety of drinks like white wines, rosé wines, beers, juices, cavas, champagne, etc. in ambient temperature conditions until moment they are requested by the client. By the present invention the beverage may be at the temperature desired by the consumer in a very short time, just a few minutes from which is requested by the client.

The equipment allows simultaneous cooling of a variable number of packaging with drinks, exposing later two examples of practical realization with three and four packages respectively, but obviously that number can vary so much in positive as negative sense without affecting the essence of the invention.

Background of the invention

The optimum consumption temperature of many Drinks certainly do not match the ambient temperature of storage of bottles or containers that contain them.

Hence it is usual in establishments of hospitality keep a number of bottles or containers of each mark inside cold stores until requested by the clients. The problem is that these cameras require some time considerable, several hours, to get the drink (especially white wines, champagnes and champagne) reach the desired consumption temperature. In case the bottles run out of a particular brand or type of drink, it is not possible to replenish new units at an optimal temperature in a reasonable time of Wait by the customer. This would force to use a space excessive in conventional cold stores if you want be prepared for any customer request, or to limit the available drinks menu, or finally to have to recognize before the client that the service cannot be provided that you asked for.

From the point of view of the establishments, it is interesting to save storage space in cameras Conventional refrigerators, save as for older investments in this type of cameras, as well as having a letter of drinks much wider than what you could have if you were limited by the capacity of its conventional cameras. From the point of view of the client, there is no doubt his preference for a establishment where there is no problem of being served Wine, cava or warm beer with food. For this it is necessary achieve ultra-fast or instant beverage cooling of so that the waiting time from its election by the client.

Currently there are means that allow virtually instant cooling of certain drinks at bulk, as is the case with draft beer, based on making circulate the drink through refrigerated coils, which allows a fast heat exchange

As for bottled drinks it is also known the use of a coolant, either by immersion of the bottle or container in it, either by placing it in a next position. In both cases, various systems of coolant mobilization, in theory to maintain some optimal thermal transmission conditions with the bottle or container concerned.

Among these systems are those based in propellers or other electro-mechanical means that they require the inclusion of an engine in the equipment, which drives a shaft in which in turn are located the propellers that provide the recirculation to the fluid. The shaft and the propellers are located in the reservoir where the fluid is located, but the engine must be placed outside that deposit, being necessary to ensure proper tightly sealed tank tightness for this purpose. These systems are much more complex and expensive (both in its manufacture as in consumption) than the one proposed by this invention and in the medium term give problems of lack of tightness and therefore coolant leaks that affect the equipment machine electronic, as a result of natural wear which affects the seals with which attempts are made to waterproof the holes through which the shafts are introduced.

Another major drawback of these systems is the high and annoying noise emitted by the agitation engine when the machine is in operation, which joins the already in itself considerable noise emitted by the refrigeration unit compressor responsible for cooling the thermal transmission fluid.

Systems based on recirculation pumps, more similar to the one of the invention now proposed, they have never arrived to be commercially exploited due to the poor design of cooler tank structure, always in prismatic form rectangular that prevents correct liquid recirculation coolant, due to the incorrect choice of type of pumps or even for the incorrect location and disposition of them, failing in the attempt to obtain an effective thermal transmission to Packaged drinks.

In both cases, the teams used complex procedures that forced volume and weight exaggerated for a comfortable installation and mobility of them in a hotel establishment, problem that is also solved with the present invention when turning the equipment into a piece of furniture Domestic volume and weight acceptable in any bar or hotel establishment countertop.

Description of the invention

The invention relates to a cooler of packaged liquids, an apparatus that makes refrigeration possible almost immediately of the liquid contained in the bottle or container to the desired consumption temperature.

It is based on the immersion of the bottle or container in a coolant with very low point of freezing, around -45ºC. Its novelty lies in the special characteristics of the reservoir containing the liquid cooler, from the equipment condenser location system space-saving refrigerator and in the exchange system thermal that allows cooling of the packaged beverage in a minimum time, much less than any other existing system nowadays.

The furniture that contains all the elements of the equipment consists of a single piece of plastic material, constituted by an internally hollow polyethylene body. This hollow space defined by the outer walls is filled with a layer of polyurethane foam or similar plastic material, which gives the piece mechanical resistance at the same time as a good thermal insulation and the consequent energy saving. Set  It is also much lighter in weight and therefore more easily  translatable than a conventional chiller with sheet metal structure metallic and the materials used do not adhere, so that They can be easily separated for later recycling.

Inside this piece of furniture there is a vat or cylindrical reservoir that we call exterior, and within it another tank or cylinder called interior of smaller diameter. Both vats are filled with the liquid that will be used for the thermal exchange with the packaged beverage, which should have a low freezing point, around -45ºC. Inside the tank or inner cylinder the baskets containing the containers are located with the drinks you want to cool.

The refrigerating group condenser, distributed in the form of a spiral or external coil, it is located between both cylinders The evaporator, distributed in a spiral or internal coil is housed inside the tank or cylinder inside, in the part closest to the baskets with drinks packaged.

From the refrigerator group, only the compressor It is located outside both cylinders. The space saving is manifest, also taking into account that it is not necessary to install a fan that cools the condenser, since it is cooled by contact with the reservoir fluid itself. This group refrigerator is able to supply the exchange liquid thermal temperature below -35 ° C. The temperature of Thermal transmission fluid work must be maintained by below the indicated figure of -35ºC, so inside the tank internal cylindrical and in contact with the said liquid there will be a thermostat that will control the operation of the compressor. This It will only be put into operation if the temperature rises by above the indicated working temperature.

As for the thermal transmission system, it based on coolant circulation through a pump Modular hydraulics located in the center of the tank or cylinder inside, which absorbs the coolant through several holes of entrance located in one of its lateral faces and expels it by several exit holes located on the opposite side with a slight gradual deviation from the direction of entry, so that this action, together with the cylindrical shape of the tank, causes a continuous circular motion while the pump is in functioning.

On the other hand, the fact that the pump is Modular allows to locate the entrance and exit holes (a couple for each module) at different heights, oriented respectively to the upper, middle and lower parts of each bottle or container In this way the cooling is uniform throughout the entire package, unlike other systems that do not they managed to raise the fluid flow to the top of bottles or containers, with the consequent thermal difference of the packaged beverage, between the top and bottom.

The dynamic action manages to generate a thermal exchange and therefore optimal and faster cooling than any other system currently known, with a decrease of packaged beverage temperature, between 8º and 10º per minute, depending on the characteristics and thickness of the container, but also in a silent and economical way like no other system has Got to date.

At the top of the machine there is a digital reader indicating the temperature at each moment the coolant contained in the tank and a pilot of Compressor operation indication. Next to them stands a digital clock in which the user must select the time you want the hydraulic pump to work for the movement of the refrigerant fluid, which functions as a countdown until stops the operation of the pump when it reaches zero.

The dimensions of the set, considered even for cooling three or four bottles of those of larger size existing in the market as those called "magnum", would not be greater than 40 cm. height, 40 cm. wide and 50 cm. background.

This allows for easy location at the counter of a hotel establishment within immediate reach of the waiter serving drinks and easy mobility within different tables areas in a restaurant, or the different rooms of A hotel that wants to provide this service to its customers.

Optionally and for cases where space does not be a problem and it is convenient to cool a greater number of containers simultaneously, a condenser can be installed conventional outside the cylindrical cover, in the same housing side where the compressor is located.

Preferred Embodiment of the Invention

As seen in the figures outlined, a preferred embodiment for beverage cooling equipment Packaged of the present invention comprises a piece of furniture (1) which it contains all the elements of the equipment, constituted by a body of internally hollow polyethylene. This hollow space defined by the outer walls is filled with a layer of foam polyurethane or similar plastic material, which contributes to the piece mechanical resistance at the same time as good thermal insulation and the consequent energy saving. The set is also much lighter in weight and therefore more easily transportable than a conventional cooler with sheet metal structure and the materials used do not adhere, so that they can be Easily separated for later recycling.

Inside this piece of furniture there is a vat or cylindrical tank that we call exterior (2), and within it another tank or cylinder called inner (3) of smaller diameter. Both tanks are filled with the liquid (4) that will be used for thermal exchange with the packaged beverage, which should have a low freezing point, around -45ºC.

Inside the tank or inner cylinder are located the baskets (5) formed by metal rods containing the beverage containers, surrounded by a flexible membrane of plastic or similar that prevents direct contact of the container with the coolant (4).

The refrigerator group condenser (6), distributed in the form of a spiral or external coil, it is located between both cylinders The evaporator (7), distributed in a spiral or internal coil is housed inside the tank or inner cylinder, in the part closest to the baskets with the packaged drinks

From the refrigerator group, only the compressor (8) It is located outside both cylinders. The space saving is manifest, also taking into account that it is not necessary to install a fan that cools the condenser, since it is cooled by contact with the reservoir fluid itself. This group refrigerator is able to supply the exchange liquid thermal temperature below -35 ° C. The temperature of Thermal transmission fluid work must be maintained by below the indicated figure of -35ºC, so inside the tank inner cylindrical (3) and in contact with said liquid (4) there will be a thermostat (9) that will control the operation of the compressor (8). This will only be put into operation if the temperature rises above the working temperature indicated.

As for the thermal transmission system, it based on coolant circulation through a pump Modular hydraulics (10) located in the center of the tank or cylinder inside, which absorbs the coolant through several holes input (11) located on one of its side faces and ejects it by several exit holes (12) located on the opposite side with a slight gradual deviation from the direction of entry of so that this action, together with the cylindrical shape of the tank, causes continuous circular motion while the pump is It is in operation. Moreover, the fact that the Modular pump allows locating the inlet and outlet holes (one pair per module) at different heights, oriented respectively to the upper, middle and lower parts of each bottle or container This achieves uniform and efficient cooling. throughout the entire container.

At the top of the machine there is a digital reader (13) indicating the temperature at every moment the coolant contained in the tank and a indicator (14) for compressor operation indication. Beside they place a digital clock (15) in which the user must select the time you want the hydraulic pump to work for the movement of the refrigerant fluid, which functions as a countdown until the pump stops working at reach zero and a pump start button (16).

An alternative planned for cases in the that space is not a problem and you want to cool simultaneously a higher number of packages, consists of installing a conventional condenser (17), in the cabin provided for locate the compressor (8), as shown in figure number 3, being cooled by a tangential centrifugal fan protected by an external housing (18).
