FIELD OF THE INVENTIONThe present invention generally relates to an icemaker for making ice cubes that are transparent.
BACKGROUND OF THE INVENTIONThere have been several attempts to manufacture transparent ice cubes of high quality by agitating water in ice cube trays during the freezing process. There are two separate and equally important aspects that determines the quality of a transparent ice cube, non-visible bubbles, and non-visible crystallization in the ice cube. The present invention addresses those two separate issues.
DESCRIPTION OF RELATED ARTOne of ordinary skill in the art knows there are different degrees of clarity in “clear ice cubes.” Even an ice cube made without one directional freezing in the home freezer that has visible crystallization has parts that are clear. The degree of clarity is paramount for transparent ice cubes for the degree of clarity determines their commercial value over much less expensive and generally smaller cloudy ice cubes. Does one visible bubble constitute clear? Does one visible crystal constitute clear? To the extent the broadest reasonable interpretation of the word “clear” is used, then are they clear of all bubbles, and all debris, and all crystallization, under magnification? See citation Slide of Microscopic Bubbles in Water. The terminology “clear” is ambiguous with respect to transparent ice cubes unless “clear” is described by text related to a specific drawing (s) pointing out the clarity and concisely expressing how the ice cube is to be viewed. Creating a center of an ice cube that is void of visible crystallization and is void of a visible air bubble creates a high-quality transparent ice cube. Disclosures that infer to not trap air in “clear ice” may teach away from the present invention as the present invention creates a transparent ice cube with air molecules in the center of the ice cube and the center is void of a visible air bubble and void of visible crystallization.
SUMMARYThe terminology “visible” herein means what a human having 20/20 vision in both eyes sees without visual enhancement in the sunlight. The terminology “ice cube” or “cube” herein is not limited to a size or shape and means any shaped or sized ice. The terminologies “includes” and “including” are intended to be inclusive in a manner similar to the terminology “comprising.” Similarly, the terminology “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”). Approximating language, as used herein throughout the specification and claims, is applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a terminology, such as “about,” “approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value. For example, the approximating language may refer to being within a ten percent margin. The terminology “motor” herein may refer to any suitable drive motor and/or transmission assembly. The term “ice mold” means any structure that water is frozen in. Work of Applicant's to the extent it is described in this disclosure, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure. The present invention incorporates herein all related art submitted in the Information Disclosure Statements in their entireties.
An aspect of one embodiment of the present invention is having the right combination of proper water movement, a properly configured ice mold and properly configured refrigeration setup to make a transparent ice cube with a center void of visible crystallization and the center is void of a visible bubble. The releasing of bubbles is not the science behind making a transparent ice cube but a result of the process. As an example, take a short glass and fill it half full of water that has no visible bubbles. Stick your finger in the water and stir. You will see your finger movement creates visible bubbles such as any agitation means would. All bubbles can never be eliminated no matter how long you agitate the water.
An aspect of one embodiment of the present invention discloses a proper frequency and amplitude combination to make a transparent ice cube utilizing a vibration or oscillating system so a person with or without a scientific instrument can do so. Amplitude is the intensity of the water movement while frequency is the rate of the movement. Embodiments of the present invention using either vibration or oscillation, a proper amplitude intensity is achieved when water droplets jump above the water surface and most preferably jumps over one eight of an inch above the water's surface. The amplitude can be too high. As an example and not limitation, when an ice mold is filled with water and a maximum amplitude for a high frequency is applied all the water may either jump out of the mold, or super cold droplets from the bottom of the water may come to the surface and may freeze the surface water if the mold has a lid and that may result in the surface becoming slushy and milky looking. Further the high amplitude may create an uneven freezing of the water to the degree it creates a cloudy cube because it adversely affects the pressure in the water. If either of these events happen the amplitude is adjusted downward. As an example, and not limitation to increase amplitude in one embodiment of the present invention, from a system using an eccentric vibrator, weights are adjusted or added or subtracted to increase or decrease amplitude. In one embodiment, the disclosed amplitude creates a high-pressure region and a low-pressure region in water within the ice mold and at a point where the water turns into ice the pressure is such that air molecules are at that point and frozen while above that point the pressure is such that air is visible to unaided eye as it rises to the surface as a visible bubble. Therefore, an air molecule is in the center of the ice cube of the present invention and a visible bubble is not frozen in a center of the ice cube.
In one embodiment of the present invention, a proper frequency is achieved when the frequency is adjusted for the total mass moved until the amplitude is such that water droplets jump above the top surface of the water in multiple ice molds.
The creation of high- and low-pressure regions within water in an ice mold is described and shown herein by way of example and not limitations as the present invention contemplates all ways to create the proper pressure regions in all devices disclosed herein to make an ice cube having a center void of a visible bubble and void of visible crystallization and all ways fall into the scope of the present invention. The amplitude described and shown herein is by way of example and not limitation as the present invention contemplates all ways to create the proper pressure differences in water so at the point the water turns to ice visible bubbles are not frozen in the center of an ice cube. The adjustment of amplitude in a vibrator is described by way of example and not limitation as the present inventions contemplates all ways to provide a proper amplitude and/or pressure regions in all devices disclosed herein to make an ice cube having a center void of a visible bubble and void of visible crystallization and all ways fall into the scope of the present invention. An ice cube can be crystal clear and still have numerous bubbles.
Another aspect of the one embodiment of the present invention is preventing visible crystallization in the center of a transparent ice cube. Atmospheric gases such as nitrogen and oxygen can dissolve in water. The amount of gas dissolved depends on the temperature of the water and the atmospheric pressure at the air/water interface. Colder water and higher pressure allow more gas to dissolve; conversely, warmer water and lower pressure allow less gas to dissolve. Air has atoms in the form of molecules, herein referred to as air molecules, or noble gases, herein referred to as gases. When water freezes it usually passes from the liquid to the solid state. As a liquid, water molecules are in constant motion, bumping and jostling each other and never staying in one place for long. When water freezes, the molecules slow and settle into place, lining up in regular formations you see as crystals. One embodiment of the present invention provides a proper water movement pressure inside a properly configured ice mold, so the molecules do not line up to the degree they cause visible crystallization in the center of an ice cube. Crystallization can form in ice without visible bubbles in water. Take a metal cup and fill with water. Be sure there is no visible bubbles in the water. Freeze the water and it will crystalize.
Another aspect of one embodiment of the present invention is to provide a proper refrigerant and superheat for a piped system and an ice mold combination to make a high-quality transparent ice cube having a center void of visible crystallization and void of a visible bubble by using one directional freezing or substantially one directional freezing through a wall of an ice mold. “Ice machines generally use low superheat valves (values) around 2 F to 4 F.” See citation Ice Machine Service Fundamentals, by Danny Moore director of technical support at Hoshizaki America, Inc. One embodiment of the present invention uses a much higher superheat. Superheat is a calculated value by taking the difference between two temperatures. First you find the actual temperature of the refrigerant vapor and then you need the saturation or boiling point of that same refrigerant. The temperature that you measure on the refrigerant should be higher than what your boiling point/saturation point is on the refrigerant. If it is not, then you have no superheat. Superheat can be determined by subtracting the boiling point/saturation point of the refrigerant from the actual temperature of the refrigerant vapor. As an example, and not limitation, if you have a forty-five degrees boiling point and your actual refrigerant temperature is at fifty degrees then you have a superheat of ten degrees. To saturation or boiling point temperature you will need to use the low side on refrigeration gauges set to measure the pressure of the evaporator. Once you have this pressure you can then convert it to a temperature either using a gauge or a PT conversion table. One embodiment of the present invention uses a superheat of between ten degrees Fahrenheit and fifty degrees Fahrenheit and more preferably about thirty degrees Fahrenheit. One embodiment of the present invention uses a refrigerant having a boiling point of less than minus twenty degrees Fahrenheit and more preferably a boiling point less than minus forty degrees Fahrenheit. Home refrigerators having a freezer compartment are generally configured to use a refrigerant having a boiling point temperature of only about minus fifteen-point four degrees F. R-134a is currently the prime example. See related art citation entitled Freon. Using the preferred superheat, an ice mold is made from either a inorganic polymer having a bottom wall thickness of less than about three quarters of an inch and more preferably less than about 0.126 inches thick, or a thermoplastic polymer having a bottom wall and sidewalls with a thermal conductivity of less than 0.055 watts per meter-Kelvin and a thickness of less than 0.090 inches and more preferably less than 0.070 inches thick and most preferably less than 0.040 inches thick, or has a bottom wall made of a material having a thermal conductivity over ten watts per meter-Kelvin and more preferable over two hundred watts per meter-Kelvin and sidewalls made from of a polymer. In one embodiment, the thermal conductivities are measured at an ambient temperature of between about zero degrees Celsius and twenty degrees Celsius.
Another aspect of one embodiment of the present invention is configuring the system to purposely move the refrigeration piping. It is known by one of ordinary skill in the art that purposely oscillating, vibrating or in general moving the refrigeration piping is not recommended as it may decrease the life of the refrigeration components including possible leakage of the refrigeration pipe at the pipe joints. For this reason, ice cube machines are generally not engineered to purposely vibrate the refrigeration pipe. The present invention provides features to mitigate this issue such as but not limited to a vibration isolator as the present invention contemplates all ways to mitigate the damage to a refrigeration pipe by movement of the pipe and all ways fall into the scope of the present invention.
Another aspect of one embodiment of the present invention is a high-volume transparent ice cube machine for bulk ice cube sales. This embodiment inserts a small spinning mechanism into water in an ice mold. It spins water against a cylinder-shaped freezing surface that most efficiently provides one directional freezing of the water inward from all sides towards the spinning device. In one embodiment, the spinning device is heated to regulate freezing time and help regulate the quality of the transparent ice cube and the diameter of the heated spinning device is one way to determine the cubes size. After the water is frozen the spinning device is removed from the mold automatically ejecting the ice cube which is substantially round in shape. The present invention contemplates hundreds of these devices hooked up in tandem in a grid freezing format used by bulk producers of cloudy ice cubes. An embodiment of the present invention meets the energy standards set forth in the Federal Code For Automatic Ice Makers Title Ten, chapter two, circa 2022. A goal of one embodiment of the present invention is to reduce the cost of making transparent ice cubes near to the cost of cloudy bagged ice cubes in the hope that transparent cubes will be used for all beverages.
Another aspect of one embodiment of the present invention is transforming a larger transparent ice cube produced by Applicant's invention having a center void of visible crystallization and void of a visible bubble into smaller ice cubes. In one embodiment, this goal is accomplished through specially configured saws to efficiently cut larger cubes into small cubes of less than six ounces each. One embodiment uses a concentrated stream of air, or a concentrated stream of water, or heat such as but not limited to a heated grid, or laser, or steam to cut ice cubes. In one embodiment, the saw has a speed of 1,000 to 8,000 surface feet per minute and more preferably 1,500 to 2,500 surface feet per minute and two to ten teeth per inch and more ideally about four teeth per inch to turn larger ice cubes into smaller ice cubes of less than six ounces reducing the chance of the ice cube chipping when cut. Further disclosed are various ways to break up the larger ice cubes without crushing or otherwise destroying them. The resulting ice has a top surface that is substantially level requiring no vacuuming of water. When using heat, air, or water to cut the ice it is preferable that the ice measures about two inches thick.
Another aspect of one embodiment of the present invention is to provide an evaporator (freezing surface) that helps distribute a proper amplitude to water in each ice mold. Essentially, metal is elastic and transmits vibrations easily while plastic is viscoelastic and does not transmit vibrations nearly as well. The present invention contemplates all metals having a well-organized crystalline lattice structure and all material having a well-organized crystalline lattice structure fall into the scope of the present invention. The method for obtaining the frequencies and orthogonality relation for combined dynamical systems in which the Green Functions of the vibrating subsystems are used is applied to a thick plate carrying concentrated masses. The effects of transverse shear and rotary inertia of each mass is accounted for. It is demonstrated that as the plate thickness goes to zero the results of thin plate analysis are obtained. The Green Functions for both thin and thick vibrating plates are derived by modal analysis in the form of infinite series. Physically, the Green's Functions of the steady-state vibration equations are the deflection of its steady-state response due to a unit concentrated harmonic stimulus acting at an arbitrary position. With respect to one embodiment of the present invention when using Greens Functions the optimal metal thickness range to help distribute the amplitude to each ice mold is between one sixtieth of an inch and three eights of an inch thick. Further the footprint size of the freezing surface under the ice mold extends to the size or larger than the size of the footprint of the ice mold. As an example, and not limitation when the ice mold is ten inches by ten inches the freezing surface will be at least ten inches by ten inches.
Another aspect of one embodiment of the present invention is meeting various USA and Canadian standards. One embodiment of the present invention meets the standards set forth in NSF/ANSI 2 Food Equipment, NSF/ANSI 7, Commercial Refrigerators and Freezers, NSF/ANSI 8, Commercial Powered Food Preparation Equipment and NSF/ANSI 12, Automatic Ice Making Equipment, all circa 2022. Further one embodiment meets Canadian CSA C742-15, circa 2022.
Another aspect of one embodiment the present invention is to allow a user to change the ice molds so the system can make a variety of different shaped and sized transparent ice without needing a tool to remove the ice tray from a freezer compartment of a refrigerator and without removing the oscillation system from a freezer compartment. Most automatic ice makers are presently configured so only the manufacturer can change the ice cube mold. The removal of the ice cube tray the ice is made in is not part of the normal operation of these automatic ice makers. One embodiment of the present invention is configured so only the ice mold is removable from the transparent ice machine without having to remove a segment of the water movement system from a freezer compartment of a refrigerator.
Another aspect of the present invention is to provide a corrosive resistant evaporator or freezing surface having a corrosive penetration rate less than five mils per year where the freezing surface also has a heat conductivity higher than fifteen watts per meter-Kelvin and the freezing surface provides a proper attenuation to help distribute a specified frequency and amplitude combination to multiple ice molds. As an example, and not limitation one embodiment of the present invention accomplishes this goal by using ceramic. To calculate the corrosion rate is assuming uniform corrosion over the entire surface of the coupon. mpy=(weight loss in grams)*(22,300)/(Adt) mpy=corrosion rate (mils per year penetration) A=area of coupon (sq. in.) d=metal density of coupon (g/cm 3) t=time of exposure in corrosive environment (days).
Another aspect of one embodiment of the present invention is to provide an ice tray the ice cubes are made in used as end user packaging eliminating the cost of repackaging associated with bulk ice cube sales. There is no related art for transparent ice cubes sold in the ice tray the ice cubes were made in except for one embodiment of the present invention.
Another aspect of one embodiment of the present invention is to add a flavor to the water and a handle creating an ice treat that is substantially void of visible crystallization. Freezing of water requires at least a certain concentration of flavor so the flavor can be tasted after the ice is frozen. In other words, water having one concentration of a flavor may taste less flavorful after freezing. In one embodiment of the present invention, the flavor added to water is about 0.2 percent by volume or more. The present invention contemplates all ways to make an ice cube that is substantially void of visible crystallization in the center and void of a visible air bubble in the center made from a variety of ingredients, including but not limited to natural flavors non-oil-based flavors, minerals, vitamins, amino acids, medicine, sweeteners, or fruit.
Another aspect of one embodiment of the present invention is to provide an ice mold lid that compensates for the opposing BTUs freezing the water. In one embodiment of the present invention, a lid covering the ice molds is calibrated to the BTU output of the refrigeration system piping under the molds to allow warm room temperature air above the lid to go through the lid to counter the BTUs in a refrigeration pipe under the mold to prevent the top surface of the water from freezing before the water under the surface yet allows all of the water to eventually freeze in the molds. As an example and not limitation one embodiment of the present invention accomplish this goal is by using a refrigeration system rated to deliver twenty-four hundred BTUs and rated with a room air temperature of seventy degrees Fahrenheit subjected to the top of the lid and the lid having a thickness of less than 0.016 inches. The present invention contemplates all ways to provide a lid that compensates for the BTU output and all ways fall into the scope of the present invention.
One embodiment of the present invention utilizes a water movement system comprising either an eccentric weight vibrator or a voice coil, or a stepper motor, or a servo motor or an impact vibrator or a magnetic force. In one embodiment of the present invention, the water weight, refrigeration piping weight if it is to be moved, the bin weight if it is to be moved, etc., are added up and then the water movement system is configured and calibrated to provide over one-half pound of force for each pound of the total weight and more preferably over one and a half pounds of force for each pound.

- setting a superheat on said refrigeration system between fifteen degrees Fahrenheit and forty-five degrees Fahrenheit;
- providing a mold having a bottom wall made of either an inorganic polymer having a thermal conductivity over one 140 watts per meter-Kelvin and a thickness of less than three quarters of an inch or a mold made of a thermoplastic polymer having a thermal conductivity less than 0.55 watts per meter-kelvin and a thickness of less than 0.070 of an inch;
- providing a water movement system;
- configuring said mold and said refrigeration system and said water movement system so said water freezes substantially in one directional through said bottom wall of said mold to produce a large ice cube that has a center that is void of visible crystallization and said center is void of a visible bubble;
- providing a gangsaw having a blade with a chromium content of over fourteen percent and a tooth count of two to ten teeth per inch;
- cutting said large ice cube into smaller ice cubes where said smaller ice cubes have a center that is void of visible crystallization and said center is void of a visible bubble.
19. The method of claim 18, wherein said mold provided has four defined sidewalls.
20. A method to make transparent ice cubes, comprising the following steps in any order:
- providing a refrigeration system configured to use a refrigerant having a boiling point of less than minus twenty degrees Fahrenheit;
- setting a superheat on said refrigeration system between fifteen degrees Fahrenheit and forty-five degrees Fahrenheit;
- providing a mold having a bottom wall made of either an inorganic polymer having a thermal conductivity over one 140 watts per meter-Kelvin and a thickness of less than three quarters of an inch or a mold made of a thermoplastic polymer having a thermal conductivity less than 0.55 watts per meter-kelvin and a thickness of less than 0.070 of an inch;
- providing a water movement system;
- configuring said mold and said refrigeration system and said water movement system so water freezes substantially in one directional through said bottom wall of said mold to produce a large ice cube that has a center that is void of visible crystallization and said center is void of a visible bubble;
- providing either a concentrated air stream, or providing a concentrated water stream, or providing a tumbling device without cutting blades, or providing a jarring device, or providing a heated grid, to either cut said larger ice cube into smaller ice cubes or break said larger ice cube into smaller ice cubes without crushing said larger ice cube, where said smaller ice cubes have a center that is void of visible crystallization and said center is void of a visible bubble.
