FIELD OF THE INVENTION

The present invention generally relates to an icemaker for making ice cubes that are transparent.

BACKGROUND OF THE INVENTION

There 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 ART

One 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.

SUMMARY

The 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.

This Summary of the Invention is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

DETAILED BRIEF OF THE PREFERRED EMBODIMENTS

FIG. 1 shows transparent ice cube maker 101 having, refrigeration pipe 102 and compressor assembly 100 and combination expansion valve capillary tube 103 and high pressure/low pressure cut in—cut out in control 106 and air moisture drier 104 that reduces or more preferably eliminates moisture in refrigeration pipe 102. The expansion valve 103 is either a thermal expansion valve, manual valve, automatic expansion valve, electronic expansion valve, low-pressure float valve, or a high-pressure float valve. In one embodiment of the present invention, freezing surface plate 109 is an evaporator segment of transparent ice maker 101. In one embodiment, the thermal conductivity of plate 109 is over 15 watts per meter-Kelvin and more preferable over two hundred and fifty watts per meter-Kelvin. In one embodiment, compressor 100 is a reciprocating compressor or a V belt compressor.

Cart 105 has vibration adjusters 107 (also known as vibration isolators or vibration dampeners), is shown in one embodiment of the present invention between cart 105 and bin 108. Vibration adjusters 107 are attached to any segment of transparent ice cube maker 101 including various places on mold 111 and number between one, two, three, four or more. Vibration adjustors 107 are shown by way of example and not limitation. The present invention contemplates all configurations of vibration adjustors 107 and all configurations and materials fall into the scope of the present invention. In one embodiment of the present invention, expansion valve 103 is configured with compressor 100 to provide a superheat of between ten- and fifty-degrees Fahrenheit and most preferable about thirty-five degrees Fahrenheit. In one embodiment of the present invention, the height of ice mold 111 is such that when an amplitude is subjected to water therein (not shown), water does not splash outside mold 111. In one embodiment of the present invention, vibrator 115 is attached to insulating cover 114 and insulating cover 114 goes over mold 111 to vibrate mold 111. In one embodiment of the present invention, cover 114 is heated to heat the top surface of water (not shown) in mold 111. In one embodiment, mold 111 is made from a plastic that is free from bisphenol A. In one embodiment of the present invention, vibrator 115 is located under freezing surface 109 and freezing surface 109 is made from corrosive resistant material. In one embodiment of the present invention, cavities 112 are made from either a thermoplastic polymer or an inorganic polymer. One embodiment of the present invention provides that cavities 112 are flexible. In one embodiment of the present invention, mold receiver 110 sits atop freezing surface 109. Mold receiver 110 provides insulation to the cavities 112 as cavities 112 insert into mold receiver 110 so that when water (not shown) is put in the cavities 112 the cavities 112 touch a segment of the mold receiver 110 sidewalls 113. The mold receiver thus provides one directional freezing of water. The mold receiver 110 is shown by way of example and not limitation as the present invention contemplates all ways to provide one directional freezing of water and all ways fall into the scope of the present invention.

In one embodiment of the present invention, vibrator 115 is attached first to rigid metal plate 115B and then the rigid plate 115B is attached in various ways to the transparent ice maker 101. Nob 115A allows a user to increase or decrease the frequency and amplitude.

FIG. 2 shows freezing surface 109 having refrigeration pipe 119. In one embodiment of the present invention, vibrator 115 is located under member plate 119A. Member plate 119A is made of plastic, rigid foam, metal, wood, or another material and is in a variety of shapes and sizes. In one embodiment of the present invention, member 119A is an insulator having a thermal conductivity of less than 0.55 watts per meter-Kelvin. Pipe 119 is a freezing surface. In one embodiment of the present invention, member plate 119A is a means to hold refrigeration pipe against freezing surface 109 or a certain distance from freezing surface 109. In one embodiment of the present invention, vibrator 115 oscillates refrigeration pipe 119.

Member plate 119A is located under refrigeration pipe 119 and therefore refrigeration pipe 119 is located between member 119A and freezing surface 109. Vibrator 115 is shown under member 119A which vibrates refrigeration pipe 119, a refrigerant (not shown) inside refrigeration pipe 119 and surface 109 simultaneously. In one embodiment of the present invention, water 200 is flavored.

In one embodiment of the present invention, refrigeration pipe 119 has a heater 120A to heat a refrigerant (not shown) in refrigeration pipe119. In one embodiment of the present invention, liquid refrigeration line 119D has a warm liquid or warm gas inside (not shown) so when refrigeration line 119D is placed in close proximity to refrigeration pipe 119 it heats a cold refrigerant (not shown) inside refrigeration pipe 119 to the degree it does not flow back to and freeze compressor 100 in FIG. 1 and damage the compressor. In one embodiment of the present invention, a segment of refrigeration pipe 119 is heated with electric heater 119E. In one embodiment of the present invention, heater 119E is a heat warp and pulls less than six ampere.

FIG. 3 shows transparent ice cube mold 130 made from an inorganic polymer or a thermoplastic polymer having sidewalls 131 and bottom wall 132 having a thickness of less than 0.090 inches or more preferable less than 0.070 inches and most preferably less than 0.040 inches when made with thermoplastic. When made with an inorganic polymer the bottom wall 132 has a thickness of less than three quarters of an inch and more preferable less than about 1.26 inches. Bottom wall 132 is substantially smooth without creases. In one embodiment of the present invention, the polymer is configured to be flexible so sidewalls 131 flex when filled with water 133 when ice cube mold 130 is outside of machine 101 in FIG. 1 Bottom wall 132, also known in one embodiment as a freezing surface when it is made from a metal material having a chromium content over fourteen percent or copper. Cold goes through bottom wall 132 and phase-transforms water 133 from the bottom position A to top position B of mold 130. Lid 130A covers transparent ice cube mold 130 to form a seal. In one embodiment of the present invention, the depth of mold 130 is sufficient so when the stated amplitude is achieved water 133 will not jump outside mold 130 when mold 130 is oscillated and mold 130 is not covered by lid 130A. In one embodiment of the present invention, water droplet 135A jumps at least one eighth an inch in the air above a top water surface 135 when a proper amplitude is applied to water 133. Transparent ice cube 133A has air bubble molecule 133B which is actually microscopic so it cannot be seen but blown up to see for this disclosure, and center 134C. Text W 134 D is behind transparent ice cube 133A and is clearly visibly void of visible crystallization in the center 134C and center 134C is void of a visible bubble. Handle 135C goes into water 133 as water 133 phase-transforms or is attached to water 133 after it phase-transforms into ice 133A. 135D is a flavor added to water 133. Standard ice cube 140B has crystallization 140C in its center portion. This represents the crystallization found in an ice cube made without one directional freezing. In one embodiment, lid 130A is calibrated to compensate for opposing BTUs and the thickness of the lid is less than 0.040 inches and more preferably less than 0.020 inches where the lid is made from a thermoplastic polymer having a thermal conductivity less than 0.055 watts per meter-Kelvin. This allows heat to go through the lid keeping a top surface of the water from freezing before water under the top surface freezes.

FIG. 4 shows impact vibrator 126 having pistons 127. In one embodiment of the present invention, the number of pistons 127 equal the number of cavities 128 having water therein (not shown) in ice mold 129. In other words, if there are 100 cavities 128, there are 100 pistons, 127. In one embodiment of the present invention, freezing surface 109 is located between transparent ice mold 129 and pistons 127. Pistons 127 are configured to hit freezing surface 109 at the exact spot cavities 128 are located above at the exact same time or at different times or to directly impact the bottom of a mold disclosed herein. This provides that the amplitude is delivered to each of the multiple cavities 128 about uniformly. Opening 129A receives freezing pipe 119 in FIG. 2 or a refrigerant (not shown). In one embodiment, vibrator 115 is shown attached to freezing surface 109. In one embodiment, pistons 127 are controlled by a microprocess (not shown) so all the pistons 127 fire at different times. The present invention contemplates all ways to fire pistons 127 at different times or at different forces and all ways fall into the scope of the present invention.

FIG. 5 shows mold 120 has cavities 121. Fill source 121 may be configured to add water (not shown) to cavities 121 in a metered dose. In one embodiment of the present invention, the water is metered a little at a time into cavities 121 as the water oscillates or vibrates. Refrigeration pipe 122 is oscillated with cam mechanism 123 and water movement device 124 that simultaneously moves refrigeration pipe 122 and cavities 121. In one embodiment of the present invention, refrigeration pipe 122 is shown under each cavity 121. If the refrigeration pipe 121 were only directly under some of cavities 121 the water (not shown) in each of the cavities 121 would phase-transform at a different rate.

FIG. 6 shows combination ice cube maker and refrigerator 136 having freezing surface 137 that in one embodiment of the present invention, mold 111 sits atop or in close proximity of two inches or closer. Mold 111 is vented to room temperature where the room temperature is above freezing or vented inside an area of refrigerator 136 that is above freezing. In one embodiment of the present invention, freezer compartment 138 is shown vented to room temperature which allows above freezing air from outside of refrigerator 136 to keep the temperature above mold 111 warm enough so the water does not phase-transform from the top of mold 111 by cold air above mold 111. Vibration Isolator 137A aids in the distribution of vibrations or oscillations to mold 111.

FIG. 7 shows ice tray 200 having lid 201 that snaps into inserts 203 to provide a seal to reduce the chance of water 204 splashing outside cavities 205 when the water 204 is vibrated or oscillated.

In one embodiment of the present invention, ice tray 200 is made of plastic and has a bottom wall 207 having a thickness of 0.040 inches or less. In one embodiment of the present invention, bottom wall 207 is made of metal having a chromium content of over fourteen percent or copper and sidewalls 206 are made of a polymer. In one embodiment of the present invention, from position top AB to position bottom BB there is at least a one-degree tapper and most preferably two degrees tapper but less than four degrees tapper.
