Definitions
- a BEVERAGE COOLER A REFRIGERATOR COMPRISING SUCH A BEVERAGE COOLER AND A METHOD FOR COOLING BEVERAGE
- the present invention relates to a beverage cooler having an in-line operating cooling unit for instant cooling of beverage flowing through the same, comprising a cooling container having an inlet pipe and an outlet pipe for feeding the beverage to and from the cooling container, respectively, and a cooling tube located inside the cooling container.
- the beverage cooler can either be built into a refrigerator, for home use or for commercial use, or be formed as a self-contained unit.
- the invention also relates to a refrigerator comprising a beverage cooler as well as a method for cooling beverage.
- Cool drink dispensers or beverage coolers are known since long time.
- the refrigerator can also be provided with a second tank for adding carbon dioxide to the water to allow dispensing of sparkling water through the dispenser.
- This cool drink dispenser comprises an in-line operating cooling unit connected to a supply source for beverage, typically water.
- the cooling unit comprises a cooling pipe, through which the beverage flows, and heat accumulating material, such as paraffin or any other similar material surrounding the cooling pipe, absorbs heat from the beverage so as to cool the beverage to a predetermined temperature.
- the cooling unit also comprises a cooling circuit, which is located in the heat accumulating material and through which a cooling fluid, such as cold air or any other gaseous or liquid cooling fluid is circulated.
- the cooling fluid can be cooled inside a freezer compartment of a refrigerator.
- the cooling circuit can also be formed as an evaporator containing a refrigerant.
- the cooling unit does not comprise the internal cooling pipe.
- the cooling unit comprises a tubular body into which the beverage is fed.
- the tubular body comprises cooling means, which cools the beverage inside the tubular body such that the beverage will freeze to a semisolid, high-viscosity mixture of frozen beverage.
- the cooling means is formed as a housing surrounding the tubular body and comprises electric fans, which on command can circulate a stream of cold air at a temperature below a freezing temperature for the beverage or a stream of warm air at a temperature above the freezing temperature.
- the cold air stream can be taken from a freezer compartment of a refrigerator, typically holding a tem- perature of between -25°C and 0 0 C, whereas the warm air stream may be taken from a fresh-food compartment of the refrigerator, typically holding a temperature of between 0 0 C and 15°C.
- a cool drink dispenser according to EP1974802A1 has some disadvantages.
- heating elements which can melt the frozen beverage when necessary. This will result in additional costs for the equipment and the introduction of a device that counteracts with the refrigeration process and thus may lead to increased power consumption.
- the above described second embodiment also necessitates the arrangement of a dedicated compartment in form of a housing surrounding the tubular body, which results in that the occupied space will increase. It also necessitates a precise sensing system for the formation of frozen beverage but prevent completely freezing of the beverage.
- EP1906120A1 from the present applicant, is disclosed an alternative appliance for supplying cooled water or other beverage.
- This appliance comprises an airtight tank for temporarily storing the beverage and the tank is connected to a source, which supplies beverage continuously to the tank. I.e. as soon as cooled beverage is dispensed from the tank, the source supplies fresh, warm beverage to the tank such that it always will be completely filled by beverage.
- the tank is either made of elastically deformable material or is a rigid container housing a closed capsule made of elastically deformable material and filled with gas.
- the tank is accommodated inside a cooling compartment, e.g. formed in a door of a refrigerator.
- the appliance comprises a number of electric fans which, on command, circulate in- side the cooling compartment a stream of cold air, e.g. taken from a freezer compartment inside the refrigerator, or a stream of warm air, e.g. taken from a fresh food compartment in the refrigerator or from outside of the refrigerator.
- a stream of cold air e.g. taken from a freezer compartment inside the refrigerator
- a stream of warm air e.g. taken from a fresh food compartment in the refrigerator or from outside of the refrigerator.
- the fans may be replaced by an evapora- tor inside the cooling compartment.
- the control device for regulating the temperature of the beverage inside the tank will be relatively complicated in order to maintain the temperature as close as possible to the freezing point and yet prevent completely freezing of the beverage and blocking of the tank, which would make it impossible to dis-patented beverage. Such a regulating including alternate warming and cooling could also lead to increased energy consumption.
- Another disadvantage associated with such an appliance is that it will require a relatively large space since the tank has to be enclosed by a cooling compartment to allow circula- tion of warm or cold air around the tank.
- the tank is so designed that, even if ice is formed therein, it can expand in a radial direction when there is a sufficient pressure of liquid at its entrance, so as to allow liquid flow.
- the tank may be designed such that some portions of the tank are positioned inside a cooling compartment while others are outside of the cooling compartment.
- US4,866,949B1 discloses a system for dispensing a chilled, carbonated water or beverage from a conventional home refrigerator.
- the beverage to be chilled and carbonated is held in a receptacle, the carbonator, having inlet and outlet for the beverage.
- a coiled evaporator either surrounds or is located inside the receptacle for cooling beverage therein.
- the beverage level in the receptacle is kept at a predetermined level by a float mechanism extending down in the receptacle leaving a CO 2 pocket within the receptacle.
- a disadvantage with the system described in US4,866,949B1 is that it is con- structed for dispensing carbonated beverage only and not for dispensing also chilled non-carbonated beverages.
- the invention also relates to a refrigerator provided with an in-line operating beverage cooler and a method for cooling beverage having essentially the same object as above. At least this object is achieved by a refrigerator according to claim 17 and a method according to claim 18.
- the basis of the invention is the insight that at least the above object may be achieved by providing a cooling container having an inlet and an outlet for allowing the beverage to flow through the container, and a cooling tube that is arranged inside the cooling container and through which a cooling fluid can be circulated.
- the cooling container is adapted to be positioned in an ambient temperature above the freezing point for the beverage, whereas the cooling fluid, circulated inside the cooling tube, is adapted to have a temperature which is below the freezing point for the beverage.
- the beverage is present between the cooling tube and an outer wall of the cooling container and can flow through the cooling container and pass by the cooling tube such that the beverage will be instantly cooled by the cooling fluid inside the cooling tube.
- the cooling container is adapted to be completely filled with frozen and unfrozen beverage.
- An advantage with this system having no trapped air or air pockets in the cooling container is that bacteria growth is prevented. Accordingly, the hygienic aspects of this system are improved.
- the frozen beverage around the cooling tube represents a cooling supply, which will contribute to the instant cooling of the beverage as it flows through the cooling container from the inlet to the outlet.
- Utilizing frozen beverage for cooling the warm beverage is advantage since a large amount of energy is required for transforming a substance in solid phase into liquid phase.
- the cooling container is located in an ambient temperature above the freezing point of the beverage, no heating means is required to ensure a free passage of non-frozen beverage through the cooling container. To have the best effect out of the system it may be around 60% to 99% of frozen beverage in the cooling container. More specific, the amount of frozen beverage may vary between 85% to 95%.
- the beverage normally being cooled in a cooler according to the invention is water and in that case the cooling unit preferably is connected to a water supply conduit, e.g. a conduit of a mains water network.
- a water supply conduit e.g. a conduit of a mains water network.
- other types of beverages with a cooler according to the invention such as e.g. juice.
- the cooler according to the invention can be arranged in a refrigerator having a freezer compartment, with a temperature typically rang- ing between 0 0 C and -25°C, and a fresh food compartment with a temperature typically ranging between 0 0 C and 15°C.
- the cooling container can be positioned in the fresh food compartment, which holds a temperature above the freezing point for water and the temperature is moreover essentially uniform and low which facilitates regulating and eliminates the need for any insulation around the cooling container.
- the freezer compartment can be utilized for cooling the beverage inside the cooling container, e.g.
- the cooling tube as part of a closed loop filled with a cooling fluid, such as for example water having an anti-freezing additive in form of e.g. salt, alcohol or glycol or a gaseous cooling fluid, and to circulate the cooling fluid through the freezer compartment, for cooling of the cooling fluid, and through the cooling container for absorbing heat from the beverage.
- a cooling fluid such as for example water having an anti-freezing additive in form of e.g. salt, alcohol or glycol or a gaseous cooling fluid
- Another possibility is to cool the inside of the cooling tube by using a thermosyphone or a heat pipe, in which a suitable refrigerant, in a loop or a single pipe, is made to evaporate inside the cooling tube.
- the condenser of the heat pipe or thermosy- phone could favourably be cooled by being in thermal contact with the evaporator of the refrigerator.
- the condenser of the thermosyphone or the heat pipe could also be cooled by an alternative means of refrigeration, such as for instance a thermoelectric refrigeration unit.
- a possible way for regulation of the temperature in the cooling tube may be performed in different ways, such as e.g. by measuring the temperature inside the cooling container a small distance from the cooling tube and to regulate a fan or a pump, which circulates the cooling fluid through the cooling tube.
- the fan or the pump may be dispensed with if measures are taken to provide self-circulation of the cooling fluid from the freezer compartment to the cooling container and back again.
- the regulating device may comprise a throttle valve, which controls the circulation of the cooling fluid.
- cooling unit instead of combining the cooling unit with a conventional refrigerator having a fresh food compartment as well as a freezer compartment, it would be conceivable to combine it with a pure freezer if the cooling container is positioned outside of the actual freezer compartment, such as completely outside of the freezer or in a dedicated space inside a door or a wall of the freezer having a temperature above the freezing point. It is also possible, as in a hereinafter described and illustrated embodiment, to combine the cooling unit with a refrigerator having only a fresh food compartment by letting the refrigerant of the refrigerator cooling system circulate also through the cooling tube.
- the cooling container com- prises a housing wherein one end of the housing is provided with the inlet and the outlet for feeding the beverage to and from the cooling container, respectively.
- the cooling tube is formed with one or more loops within the cooling container.
- an effective cooling is achieved as the build-up of a core of frozen beverage around the cooling tube is fast.
- a further advantage is a simple and cost effective construction of the cooling tube.
- the cooling tube can be provided with cooling flanges.
- the cooling tube is provided with a cooling flange, which is spirally wound around the cooling tube and extends the entire distance between the outer surface of the cooling tube and the peripheral wall of the cooling container. In this way is formed a long, narrow and spirally shaped path for the beverage to flow be- tween the inlet and the outlet. Due to this is achieved an extremely effective cooling of the beverage, since the flow path is so long, the area of exposure to cold surfaces is so large and the flow through the cooling tube will be entirely turbulent, due to the high flow speed and the proximity to surrounding walls everywhere in the cooling container. To increase the turbulent flow, the surfaces of the cooling flange can be provided with irregularities.
- the beverage closest to the cooling tube is frozen to ice, whereas a passage of unfrozen beverage is maintained at the peripheral walls.
- the cooling tube is lo- cated centrally inside the cooling container, preferably concentric with the cooling container. This is advantageous in that the formation of a layer of frozen beverage can occur around the entire cooling tube and a free passage of non-frozen beverage may be maintained closest to the entire inner surface of the cooling container.
- the outer cross sectional dimension of the cooling tube is sufficient smaller than the inner cross sectional dimension of the cooling container such that a free passage of non-frozen beverage always may be maintained somewhere in the cooling container.
- a beverage cooler according to the invention can be combined with a refrigerator in many different ways, such as a refrigerator comprising a fresh food compartment and a freezer compartment, wherein the cooling container is positioned in the fresh food compartment or outside it, for example in the back or in a wall of the refrigerator and the cooling fluid in the cooling tube is cooled in the freezer compartment.
- the beverage cooler can also be combined with a pure freezer if the cooling container is positioned outside of the freezer or in a dedicated space inside the door, in a wall or the like.
- the refrigerator do not contain any freezer compart- ment but only a fresh food compartment, it is possible to position the cooling container inside the fresh food compartment and let the evaporator of the refrigerator, or a branching from it, constitute the cooling tube.
- beverage cooler with a carbonation device for mixing carbon dioxide into the beverage, e.g. a car- bonation device as disclosed in EP1974802A1 or any other suitable kind, to obtain a sparkling beverage.
- a carbonation device for mixing carbon dioxide into the beverage e.g. a car- bonation device as disclosed in EP1974802A1 or any other suitable kind, to obtain a sparkling beverage.

- the refrigerator is in this embodiment of the type having only a fresh food compartment 3, which has a temperature ranging normally between 0° C and about 8° C.
- the refrigerator is provided with cooling radiators 4, through which a refrigerant is circulated in a conventional way known in the art, for cooling of the fresh food compartment.
- a cooling container 5 of a beverage cooler is positioned inside the fresh food compartment, according to the invention, and on the outer surface of the door is provided a recess 6, indicated with broken lines on the inside of the door in fig 1 , which contains a not shown beverage dispenser unit for dispensing cooled beverage to a user when de- sired.
- the cooling container 5 of a beverage cooler may be positioned at the back or in a wall of the refrigerator, i.e. outside the fresh food compartment.
- the refrigerator cooling system comprises a compressor 7, which is positioned outside of the fresh food compartment.
- a gaseous refrigerant fluid is compressed, which has to result that the temperature of the refrigerant is increased.
- the refrigerant is then passed through a condenser 8 where the warm gas is cooled and condensed to a liquid phase.
- the liquid refrigerant then flows through an expansion valve 9 where the pressure is lowered. This has to result that the liquid refrigerant at least partly will return to a gaseous state.
- the refrigerant passes the wall of the refrigerator cabinet and flows into the cooling container 5 of the beverage cooler according to the invention.
- the cooling container 5 is provided with an inlet 10 and an outlet 11 to admit filling and discharging of beverage to be cooled into and from the cooling container, respectively.
- the beverage to be cooled is water, so for this reason the beverage inlet is connected to a water mains network at a water net connection 12.
- the outlet is connected to the water dispenser unit 13 in the outer surface of the door.
- other kinds of beverages could be cooled by means of the beverage cooler according to the invention.
- the inlet tube is connected to a container containing the beverage instead of being connected to the water mains network.
- a cooling tube 14 is extended through the cooling container through which the refrigerant flows, i.e. the cooling tube functions in this embodiment as an evaporator, which cools the beverage flowing around it.
- the cooling tube is connected in series with the evaporator in form of the cooling radiators 4 of the refrigerator cooling system, which can be of a generally known type comprising additionally valves, sensors, control equipment, cooling flanges and the like, so as to accomplish cooling of the inside air of the fresh food compartment 3 in a desired degree.
- the cooling tube 14 is positioned centrally in the cooling container 5 and extends completely there through.
- the cooling tube 14 can preferably be formed with cooling flanges and the like for increased cooling capacity.
- the cooling container 5 is completely filled with beverage from inlet 10 and it is most likely, and also desirable, that a layer of frozen beverage will be formed in the region closest to the cooling tube 14, as is illustrated by the layer 15 in fig 3.
- the beverage will be maintained in an unfrozen state, as is indicated at 17.
- the cooling container 5 will contain stored cooling capacity in form of frozen beverage, which can be made use of when warm beverage is flowing in through the inlet in order to achieve instant cooling of the beverage.
- the cooling container 5 is al- ways completely filled with frozen 15 and unfrozen beverage 17. There are no air pockets in the cooling container 5 and thus no air is in direct contact with the beverage in the cooling container.
- a control device for regulating the cooling effect of the cooling container may in a simple embodiment comprise a temperature sensor located in the passage 17 of unfrozen beverage in the cooling container, which by means of a control circuit regulates the pressure drop in the expansion valve 9 and hence the cooling effect of the cooling tube 14.
- the control device may be set to maintain the temperature of the unfrozen beverage 17 one or a few degrees above the freezing point for the beverage. To have the best effect out of the system it may be around 60% to 99% of frozen beverage in the cooling container. More specific, the amount of frozen beverage may vary between 85% to 95%.
- a further control device is also arranged in relation to the beverage cooler to handle the overpressure created within the cooling container 5 due to the formation of ice therein, i.e. frozen beverage.
- One solution to this prob- lem is to install an overpressure valve (not shown) that releases an amount of beverage equal to the expanded volume due to ice formation.
- the valve may be arranged on the cooling container 5, the inlet 10 or the outlet 11 , or at any other point where there is open communication with unfrozen beverage.
- the beverage is drained to a drainage receptacle of the cooling appliance, i.e. refrigerator or freezer.
- Another solution to handle the overpressure may be to arrange an overpressure balloon for equalizing pressure in the system or to use flexible tubings that could slightly expand as pressure increases in the system.
- a second embodiment is illustrated in a transparent perspective view in fig 4 and a longitudinal section in fig 5.
- the cooling tube 14 is provided with a cooling flange 18.
- this cooling flange does not ex- tend only a short distance above the outer surface of the cooling tube, as is customary in connexion with cooling and heating appliances.
- the cooling flange is spirally wound around the cooling tube 14 and extends the entire distance between the outer surface of the cooling tube and the peripheral wall 16. In this way is formed a long, narrow and spirally shaped path 19 for the beverage to flow between the inlet 10 and the outlet 11.
- the cooling container 5 comprises a housing 20 for holding the cooling tube 14 inside.
- One end of the housing 20 is provided with the inlet 10 and the outlet 11 for feeding the beverage to and from the cooling container, respectively.
