Definitions

  • the present invention relates to the field of a beverage-preparing device, and more particularly, the invention relates to a personal handheld rapid slushy drink maker.
  • Slushy drinks made of a specific liquid cooled close to the freezing point appeal to children and adults who enjoy consuming beverages such as iced coffee, slushy cocktails, frozen yogurts, and smooth ice cream.
  • Slushy generally has a semi-solid composition of ice crystals surrounded by liquid. Crystals are formed when heat is removed from a liquid at such conditions that total freezing is prevented.
  • Typical home slushy makers are devices such as a blender that require the desired liquid to be mixed with ice cubes, which cools the liquid and contributes to the slushy texture of the finished product after the ice is crushed.
  • This operation has two main disadvantages - the need for previously made ice cubes and the low-quality texture of crushed ice.
  • a blender is usually heavy, noisy, and inconvenient to use.
  • Other devices, which produce the slushy by cooling the liquid are either large and therefore not portable or take a long time to prepare the slushy drink.
  • U.S. Patent Application Publication No. WO2021250682A1 discloses “a device for making slushy from a food substance contained within a container when the container and the device are exposed to ambient temperature below the freezing temperature of the food substance for a minimal time.
  • the device comprises an operation casing attachable to a top portion of the container; at least one blade configured to extend from the bottom face of the operation casing; a motor accommodated within the operation casing and operatively connected to said blade, configured to rotate said blade at least throughout continuously said minimal time, and a DC power supply to supply power to the motor.”
  • US4590852A discloses “a method and apparatus for cooling a frozen comestible plasticizer apparatus with a heat exchanger pan over a freezer, protecting the freezer from extraneous matter filling in, while providing a cool circulatable environment to cool the auger and cup of the apparatus to help avoid bacterial growth and minimize the need for cleaning of the apparatus.”
  • U.S. Patent Application Publication No. US2849868 discloses “an improved ice cream freezer, particularly a portable freezer for use in a home cold storage compartment, which is mounted on the cover of a top opening cold storage compartment.
  • an electric motor and reduction gearbox are secured to the top side of the compartment cover, and the container for the cream to be frozen is suspended from the underside of the cover.
  • An agitator in the container is driven by a shaft passing through a hole in the cover.
  • the prior arrangement is effective for its purpose. Still, it requires making a shaft hole in the compartment cover and constitutes a permanent attachment that cannot be conveniently removed when it is not in use.
  • the present invention 's general objective is to provide a portable ice cream freezer readily inserted into and removed from a refrigerated compartment.”
  • U.K. Patent Application Publication No. GB2147983A discloses, “Improved heat exchange device for a frozen food product maker.
  • the present invention involves the field of technology devices for making frozen food products in the freezing compartment of a refrigeration unit. More specifically, the invention is directed to an improved means for enhancing heat exchange between the contents of a mix canister associated with a frozen food product maker and the cold air generated by the evaporator of a refrigeration unit.”
  • the present invention's additional object is to provide a home slushy maker that can speedily produce a slushy drink.
  • Another objective of the present invention is to provide a portable, handheld device that can easily be carried and used as a drinking cup.
  • a home slushy maker comprises:
  • An inner container made of heat-conducting material, such as aluminum, within which the desired liquid is introduced.
  • the outer part of the container is built in a configuration of a ribbed heat exchanger.
  • An activation unit contains a microcontroller, the stirrer motor, a fan, and batteries.
  • slushy product is one in which suspended ice crystals form in the introduced liquid or one, such as an ice cream product that has a smooth and creamy texture that is made from milk, cream, or yogurt with added ingredients for flavor and texture, whose viscosity is increased relative to that of the initially introduced liquid as a result of the rapid cooling.
  • Fig. 1A is a perspective of an embodiment of a home slushy maker when assembled with an activation unit.
  • Fig. IB is a perspective of an embodiment of a home slushy maker when assembled with a drinking cap.
  • Fig. 2 is an exploded view of an activation unit used in conjunction with the home slushy maker of Fig. 1A.
  • Fig. 3 is an explosive view schematic illustration of the activation unit circuitry used in conjunction with the activation unit of Fig. 2.
  • Fig. 4 is a section view of the home slushy maker of Fig. 1A, cut along the longitudinal axis.
  • Fig. 5 is a block diagram of the control circuitry components and function.
  • the home slushy maker is a portable, handheld, and cost-effective device that utilizes the cooling ability of a domestic freezer to produce a slushy drink.
  • the dimensions of the home slushy maker are significantly smaller than those of a bulky commercial slushy maker, which requires a refrigerant as well as a compressor and condenser through which the refrigerant flows in a refrigeration cycle to generate the needed cold for preparing a slushy drink.
  • the home slushy maker can speedily produce the slushy drink in a small fraction of an hour after the desired liquid, and other ingredients are introduced into an internal cavity outside the freezer. Then the slushy maker is placed in the freezer and activated.
  • the speedy slushy production process is made possible using forced convection whereby cold air from the freezer interior is drawn into the internal cavity of the slushy maker and causes the introduced liquid to become significantly cooled.
  • Fig. 1A illustrates an embodiment of a home slushy maker 1000.
  • the external structure of home slushy maker 1000 is shown to include two members, the first being the activation unit 100, and the second being a cylindrical cup 200 that is shown to be coupled with activation unit 100.

  • Extension 115 attached to or integrally formed with the outer wall of activation unit casing 110, houses the control circuitry 300 needed to perform a slushy-making operation.
  • Activation unit casing 110 and extension 115 are sufficiently isolated to prevent damage to the control circuitry 300 if the home slushy maker inadvertently remains in the freezer for an extended period.
  • extension 115 can be avoided, and in such case, the control circuitry will be in a control circuitry chamber 117 inside the activation unit casing 110.

  • stirrer 230 is configured with three blades 231 angularly separated by 130 degrees, which radially extend from central stirrer shaft 234 with an axial length significantly less than blades 231, for example, one-half of their size, without radially protruding from head plate 233.
  • Each blade 231 is configured with a plurality of apertures 232 throughout its length, through which formed ice crystals can pass when being agitated so as not to accumulate along the wall of inner cup 220 and reduce the temperature of the slushy drink below the desired value.
  • the apertures 232 across the blade’s surface can have various shapes, sizes, and distributions.
  • Fan 170 is shown to be surrounded by a perforated cylindrical casing 171 that has a plurality of circumferentially spaced openings 172 to direct the drawn freezer air in specific radial directions.

  • An O-ring 160 or any other suitable sealing element, may be provided at the inner wall distal end of activation unit casing 110 to prevent seepage of the slushy drink to annular passageway 111 or motor 120.
  • Neck 222 of inner cup 220 may also be coupled to a rotatable sealing element.
  • the forced convection induced by the rotation of the blades of fan 170 draws the cold freezer air 510, e.g., at a set temperature of -18°C and at a high volumetric flow, e.g., at a rate of 1 m 3 /min, through grille 180, annular passageway 111 formed in activation unit casing 110, between the fins of the heat exchanger 221, and through discharge openings 211.
  • the air 520 temperature after being discharged from openings 211 is slightly higher than that at the inlet of grille 180, e.g., -15°C.
  • An additional cooling cycle is initiated within the freezer compartment to maintain the set temperature once the detected air temperature rises above a predetermined threshold.
  • This forced convection arrangement optimally chills the liquid that has been introduced within the cavity of inner cup 220 by supercooling and facilitates the formation of tiny ice crystals that are characteristic of a slushy drink without having to deal with the bother of preparing ice cubes, handling them and introducing them into the internal cavity together with the desired liquid.
  • the flow of cold freezer air 510 across the wall of inner cup 220 provides a relatively high heat transfer rate from the introduced liquid and would generally cause the fluid to freeze to a solid block.
  • the mechanical agitation from stirrer 230 causes the liquid temperature within the cup interior to be more uniform. Consequently, it inhibits crystal growth that would otherwise occur at the wall of inner cup 220, where heat is typically transferred out of the liquid.
  • the tiny crystals that have already been formed remain suspended in the agitated liquid and produce the slush.
  • Another cause for a reduction in the heat transfer rate from the introduced fluid is the presence of the heat sink. After home slushy maker 1000 has been repositioned from outside to inside the freezer, the heat sink is approximately equal to room temperature, reducing the heat transfer rate from the introduced liquid.
  • the presence of sugar within the introduced liquid reduces the initial freezing point of the liquid. It mitigates the bonding of water molecules that generally promote the formation of larger crystals and, eventually, solid ice. Since a sugar molecule is not integrated into the crystalline structure, the concentration of sugar in the remaining liquid increases as the percentage of the tiny crystal formations likewise increases, thus further reducing the freezing point of the remaining liquid.

  • Microcontroller 310 which has a processor that is factory programmed or is programmed using a dedicated application 531 running on a computerized device 530 such as a smartphone, selectively transmits command signals C to the fan motor 173 and the stirrer motor 120 upon demand, whether wirelessly or through a wired connection.
  • a battery 320 power microcontroller 310, fan motor 173, and stirrer motor 120.
  • the battery 320 may be rechargeable, and the activation circuitry may also comprise a battery charger.
  • the values detected by these sensors, as well as by temperature sensor 350 for detecting the temperature of the introduced liquid and temperature sensor 350 for determining the temperature of the incoming surrounding air, generally freezer air, are continually monitored throughout the slushy making operation to determine whether the predetermined consistency has been produced.
  • the current of the fan motor may be monitored throughout the slushy-making process to determine whether the fan motor has become overloaded, for example, due to blockage of the air outlet at discharge openings 211 that would seriously reduce the effectiveness of the forced convection and the slushy making operation.
  • the battery's state of charge may be acquired to determine whether the battery is sufficiently charged to power the slushy-making process.
  • the microcontroller Upon determining that the slushy drink is ready to be consumed by a combination of various factors as defined in instructions stored in the microcontroller, including a predetermined temperature depending on the type of slushy drink that is being prepared and its sugar concentration and on the predetermined consistency of the slushy drink that is being produced, the microcontroller transmits a command to adjust the fan speed, depending on whether the slushy temperature increases or decreases.
  • microcontroller 310 When factory programmed, microcontroller 310 may be activated by a manually activated activation switch 360, for example, when pressed for longer than a predetermined duration. After that, the control signal C is transmitted. A first control signal for activating the fan and stirrer may be transmitted following the activation of microcontroller 310. A second control signal for deactivating the fan and stirrer may be sent following a second predetermined duration after activation of microcontroller 310. If so desired, more than one activation switch 360 may be provided and indicated accordingly to select a slushy-making function for one of a plurality of predefined liquids, the duration of each process generally being different.

Abstract

La présente invention concerne un dispositif de préparation de barbotine à partir d'ingrédients placés à l'intérieur du dispositif. Lorsque le dispositif est placé et activé à une température ambiante inférieure à la température de congélation des ingrédients liquides en son sein, tel qu'un congélateur domestique, il crée un écoulement d'air réfrigéré à l'intérieur du dispositif. Cet écoulement d'air réfrigéré élimine la chaleur du liquide à l'intérieur par une convection forcée. Ce mécanisme de transfert de chaleur est amélioré à l'aide d'un échangeur de chaleur à ailettes à forte conductivité thermique et par entraînement du liquide en rotation à l'aide d'un agitateur à pales. Lorsque la barbotine est prête à être consommée, le dispositif envoie une indication à l'utilisateur et maintient la composition de barbotine de manière appropriée jusqu'à ce qu'elle soit retirée de l'environnement froid et consommée. Le dispositif est petit, portable, et prépare la barbotine rapidement.
