Definitions

  • the present invention refers to a portable cooling for cooling, and maintaining in a cooled or frozen condition, both solid and liquid foods, without using any power supply or adding ice; the cooling is carried out by means of a cryogenic liquid such as liquid nitrogen or liquid oxygen that works as a cooling liquid, although in embodiments of the invention the cryogenic substance may be liquid or solid CO 2 .
  • a cryogenic liquid such as liquid nitrogen or liquid oxygen that works as a cooling liquid, although in embodiments of the invention the cryogenic substance may be liquid or solid CO 2 .
  • the invention disclosed in the present specification functions because the temperature of the capsule containing the cryogenic liquid is well below zero, for example: nitrogen liquefies at -196oC and argon at -185,9oC, introducing said capsule inside the cooling device and mitigating the temperature emitted towards the outside through the insulation and transmitting through the connection ducts with the inlet, cooling the container according to the needs of the cooling device, such that any food or beverage is cooled, refrigerated, or frozen.
  • this novel invention provides to the state of the art a product for cooling or maintaining in a cooled, refrigerated, or frozen condition food or beverage without using any external power supply such as electricity, or any ice or snow as in conventional coolers and maintaining, at all times, its cooling characteristics and attributes.
  • the main novelty provided by this invention is cooling, refrigerating, or freezing food or beverage with the following advantages:
  • the invention is intended for commercial, domestic and industrial use and it encompasses a wide range of products:
  • the application field is the industry of manufacturing cooling devices for food and beverage, and more particularly the industry of manufacturing coolers refrigerated by cryogenic liquid without any electric power supply.
  • patent US 2046953 A (Kellogg John L ) of 07/07/1936, employs a cryogenic gas, not a cryogenic liquid as the present application, with no metallic contact between the cooler container and space to be refrigerated, while in the present application the system cools through the metallic connection ducts between the capsule and the inside of the container.
  • the CO 2 when transitioning to a gaseous condition, is conducted through sleeves towards the inside of the beverage barrels, is mixed with the beverage, and it causes the pressurized injection of the beverage, cooling it at the same time.
  • the present application does not have anything to do with that, since it operates for cooling any food or beverage housed inside, through the metals connected to the capsule containing the cryogenic liquid.
  • the compared patent clearly discloses that the system forms part of the supply of carbonated beverages, where it is employed for injecting, with the aid of the CO 2 in a gaseous condition, the cooled beverage, because it mixes with the beverage.
  • the two patents in the application only two valves are employed, an external, insulating housing and a capsule containing the pressurized liquid.
  • the compared one has ducts having nothing to do with the connection ducts of the application, as well as sleeves for mixing the gas with the beverage.
  • the liquid only cools, but it does not mix with the beverage, it never mixes with whatever is going to be cooled. It is only injected and it returns to the environment as gas, from the same compartment (capsule).
  • Document ES 2 008 993 14 refers to a cryogenic freezer for freezing food products and the like, comprising: an insulated enclosure having a lower inlet and an upper outlet; transporter means for moving food products along a path from said inlet to said outlet, where most part of said path is a helical section having a plurality of superimposed floors; means for having the food products, moving along said path, contact liquid nitrogen at a lower zone generally close to said inlet for initially extracting a substantial amount of heat from the surface of said food products; means for producing a generally horizontal cryogenic vapor circulation in all upper zones of said helical section, thus creating a vertical temperature gradient inside said enclosure, where there are relatively warm temperatures close to the outlet; and means for controlling vapor exit through said inlet and said outlet such that at least 80% approximately of the cryogenic vapor generated inside said enclosure exits therefrom through said upper outlet.
  • Document ES 2 106 976 T3 discloses a refrigeration apparatus having at least a first and a second refrigeration compartments, each compartment having its own access door, comprising a first evaporator for said first compartment, where said evaporator operates at a first pressure value; a second evaporator for said second compartment, where said second evaporator operates at a higher pressure value than said first pressure value; a single condenser; a single compressor; a refrigerating circuit comprising a series of ducts for sequentially providing a refrigerant flow to said first and second evaporators, said condenser and said compressor; valve means in said refrigerant circuit for conducting refrigerant to a selected one of said evaporators from said condenser and for preventing a refrigerant flow to said first evaporator when refrigerant is being conducted to said second evaporator for cooling said second compartment; a retention valve in the aspiration side duct of said first evaporator, for preventing the return ref
  • Document ES 2 289 552 T3 discloses a product cooling procedure comprising N adsorption/desorption cycles carried out under vacuum conditions, where N is an integer greater than 1, where each cycle comprises the steps consisting of: - extracting heat from a refrigerant fluid in vapor phase in a condenser at a first pressure below the critical pressure of said fluid for condensing said refrigerant flow, - introducing said refrigerant fluid in liquid phase in an evaporator at a second pressure below the first pressure for vaporizing a portion of said refrigerant fluid and cooling the remaining portion of the refrigerant fluid to a vaporization temperature of said refrigerant fluid at said second pressure, where said vaporization temperature decreases from a cycle to the next, where said first and second pressures are chosen in each cycle such that said vaporization temperature in a cycle is each time lower than the condensation temperature of said refrigerant fluid in the next cycle to the first pressure of said next cycle - providing heat to the liquid portion of said refrigerant fluid
  • Document ES 2 113 908 T3 refers to a domestic cooling apparatus having at least a cooling chamber having a closure door, where refrigerated product containers, a vaporizer and a fan supplying air from the environment and situated in the natural convection stream produced by the cooling power of the vaporized are provided, characterized in that the fan forcibly exchanges refrigerant air both during the cooling activity and during the defreezing activity such that, due to the situation and form of the refrigerated product containers and the ventilator, refrigerant air is transported to the zone of the walls of the refrigerator enclosure and along the door, covering them completely along their length and width.
  • Document ES 2 296 668 T3 is an air cooling device comprising a compressor having an inlet and an outlet, a turbo expander having a turbine rotor through which said compressor is connected to said turbo expander, a first fan mounted to a shaft shared with said turbo expander, a first double duct heat exchanger, a cooling chamber having a second fan and an air cooler mounted inside the chamber, a second double duct heat exchanger, a water tank connected to a second duct of the second heat exchanger, and a moisture separator; where a first duct of the double duct heat exchanger, a first duct of the first double duct heat exchanger, the moisture separator, the turbo expander, the air cooler, and the second duct of the first double duct heat exchanger are connected in series to the compressor inlet.
  • Document ES 2 188 161 T3 refers to a domestic cooler cooled by means of the Peltier effect, having an enclosure to be cooled formed by one or two thermally insulated enclosures, where air circulates by means of natural convection, where heat entering the enclosures is extracted by means of the evaporation of a liquid where at least one enclosure to be cooled is cooled by two cascade-coupled units, where each unit comprises two thermosiphons separated by Peltier effect granules, where one of the thermosiphons of each unit for condensing a liquid housed therein is provided on a cold side of the Peltier effect granules and where the other thermosiphon of each unit for evaporating a liquid housed therein is provided on a hot side of the Peltier effect granules, characterized in that each thermosiphon includes a first circuit for circulating the evaporated liquid towards a zone where the liquid must condense, and a second circuit for returning the liquid to a zone where it must evaporate, where
  • thermosiphons contain water as a refrigerant fluid having appropriate vacuum degrees, such that evaporation takes place at the desired temperatures in each thermosiphon.
  • the portable cooler having a connectable refrigerator, having no power supply or ice, of the present invention is made of the following elements:
  • the invention disclosed in the present specification functions because the temperature of the capsule containing the cryogenic liquid is well below zero, for example: nitrogen liquefies at -196oC and argon at -185,9oC, introducing said capsule inside the cooling device and mitigating the temperature emitted towards the outside through the insulation and transmitting through the connection ducts with the inlet, cooling the container according to the needs of the cooling device, such that any food or beverage is cooled, refrigerated, or frozen.
  • the inside temperature may be manually regulated by means of the connection ducts, by connecting or disconnecting attachment points for achieving said temperature.
  • an apparatus for recharging the cold of the cryogenic liquid through the valve is needed.
  • Said apparatus for recharging the cold is made of a cryogenic liquid or cryogenic gas bottle and an injection valve.
