Discussion of the Related Art
Ice machines commonly known in the art include hotel ice machines, commercial ice machines, beverage machines, and ice dispensers incorporated into refrigerators. Ice machines typically include elements for making the ice, including a water supply, an see cube mold, and a refrigeration unit. Ice machines also typically include elements for dispensing the ice, including an ejector and a holding container.
A typical operation of the ice machine includes temporarily opening an automatic water valve coupled to a potable water source. When the valve is open, water flows into the ice cube mold, which is located in a portion of the ice machine held at a freezing temperature. Some ice cube molds include a coating to allow for easier removal of the ice.
After a thermostat sense that the ice cubes are fully frozen, the machine activates a motor and heater. The heater loosens the ice cubes from the mold, and the motor operates the ejector/harvesting arm, removing the ice cubes from the ice cube mold.
Commercial and food service ice machines accomplish rapid ice formation by placing the evaporator coils of the refrigeration unit in close contact with the area to be frozen, using convection to freeze the ice rather than conduction through air.
Various shapes of ice cubes formed by ice machines are known in the art. Shapes include crescents, tubes, full cubes, half cubes, flakes, and bullet-shaped.

A frame of the shaped ice unit includes the vertical sidewalls 308, 324 which are in a generally rectangular plate shape. The shaped ice unit 204 is generally box-shaped, with the vertical sidewalls 308, 324 forming the sides of the box. The distance between the two sidewalls 308, 324 is approximately 8 inches. Each sidewall 308, 324 includes the generally vertical track 316.
The top mold 302 is a generally rectangular shape, with a thickness as required to accommodate the top mold cavities 326 and provide adequate stiffness and durability of the top mold 302. The top mold 302 is removably coupled between the sidewalls 308, 324 in a horizontal position, i.e. in the position of the top of the box-shape. The rectangular evap plate 300 is coupled to a top surface of the top mold 302. The evap plate 300 and the top mold 302 are configured to receive water from the water line 202 fluidly coupled to the holding tank 200, and include water access holes 338 as necessary to receive the water in the molds 302, 304. The top mold 302 includes the plurality of downward-facing cavities 326 for forming the ice pieces 114.
At a base of each sidewall 308, 324, two support bars 328 of the frame connect the first sidewall 308 to the second sidewall 324 to provide additional frame stability to the shaped ice unit 204. In the present embodiment outer dimensions of the shaped ice unit 204 are approximately 10 inches high×5 inches wide×10 inches long.
The bottom mold 304, which when coupled to the top mold 302 forms the three-dimensional mold for the shaped ice pieces 114, is located between the sidewalls 308, 324 underneath the top mold 302, and is movably coupled to the track plates 322 and the pivot bolts 332. When the top mold 302 is coupled to the bottom mold 304, a watertight seal is formed between the two molds 302, 304. In one embodiment, the seal, is provided by a rubber gasket adhered to either the top mold 302 or the bottom mold 304. The bottom mold 304 includes the plurality of cavities 306 on one side of the mold 304 such that when the bottom mold 304 is in an upper, horizontal position and coupled to the top mold 302, the top mold cavities 326 and the bottom mold cavities 306 are matched, forming a plurality of cavities forming three-dimensional shapes. The cavities 306, 326 are configured such that the ice pieces 114 are releasable from the molds when the bottom mold 304 is lowered and removed from the top mold 302. i.e., the molds 302, 304 include no reverse draft angles that would prevent the ice from being released from the molds 302, 304.
In the embodiment shown, the bottom mold 304 is coupled to the bottom mold frame 312 on a side of the bottom mold opposite to the bottom mold cavities 306. Two flanges 314 are coupled to the bottom mold frame 312, one flange 314 on each sidewall 308, 328 side. The flanges 314 are generally perpendicular to the bottom mold 304 and extend generally downward when the bottom mold 304 is in the upper, horizontal position and coupled to the top mold 302. In the lower horizontal position shown in
The bottom mold frame 312 includes the flip rod 318 oriented normal to the flanges 314, i.e. spanning between the frame sidewalls 308, 324. The flip rod 318 is located between the base of the U-shaped arms 310 and the bottom mold 304. Each end of the flip rod 318 passes through the rod track 334 of the proximate track plate 322 and through the vertical track 316 of the proximate sidewall 308, 324, such that the movement of the flip rod 318 is constrained by a path of the flip rod 318 within the tracks 316 and 334. An upper end of each track plate 322 is pivotally coupled to an upper inside portion of the proximate sidewall 308, 324 by the upper bolt 330. The track plate 322 is generally parallel to the proximate sidewall 308, 324, with the rod track 334 oriented in a generally vertical direction. The rod track 334 includes a C-shaped portion curving towards the front side 328 of the shaped ice unit 204 in a middle portion of the rod track 334. At each sidewall 308, 324 location, the pivot bolt 332 located at a middle portion of the track plate 322 distal to the front side 328, pivotally couples the proximate flange 314 to the track plate 322. A pivot bolt shaft passes through the channel 320 of the flange 314, whereby the flange 314 may rotate with respect to the track plate 322, and the translational movement of the bottom mold frame 312 is constrained, by the sliding of the pivot bolt shaft in the channel 320. The shaped ice unit 204 is thus configured such that, as the flip rod 318 is moved downward in the rod track 334 from the upmost position (i.e. the position where the top mold 302 is coupled to the bottom mold 304), the bottom mold 304 moves downward with the flip rod 318. The combination of the shape of the rod track 334, the pivoting of the track plate 322 around the upper bolt 330, the pivoting of the flange 314 around the pivot bolt 332, and the sliding of pivot bolt 332 within the flange arms 310 combine to form a mechanism that, during the downward, movement of the flip rod 318, results in the bottom mold frame 312 and bottom mold 304 rotating approximately 180 degrees, such that when the flip rod 318 has moved to the bottommost position, the bottom, mold 304 has been flipped so that the bottom mold cavities 306 are facing generally downwards. The movement of the mechanism and the bottom mold 304 are described further below in
The shaped ice unit 204 is similar in function to a conventional self-inking stamp unit. The top mold 302 and the bottom mold 304 are supported in several positions, as required for filling fee mold, freezing the ice pieces 114, and then removing the ice pieces 114 from the mold. The structural configuration shown in
The materials of the structural portion of the shaped ice unit 204 may be any material, suitable to support the overall structure and provide for operation of the mechanism as described herein. In some embodiments, most portions of the shaped ice unit are acrylic. In other embodiments, portions of the shaped ice unit may be plastic or metal.

The actuator 800 is coupled to the flip rod 318 with only one rotational degree of freedom around a longitudinal axis of die rod 318, allowing for the bottom mold 304 to spin as the bottom mold 304 is raised and lowered. A bearing-like connection between the actuator 800 and the flip rod 318 is preferred as it would allow for the flip rod 318 to rotate as it pushes or pulls the bottom mold 304.

Refrigerant piping 1000 is coupled to the compressor, and is used to cool and freeze the ice pieces 114. As shown, the refrigerant piping 1000 runs along the top of the top mold 302 in a generally zig-zag pattern. The refrigerant piping 1000 may include parallel piping, with a portion of piping 1000 for one top mold 302 in parallel with a portion of piping 1000 for another top mold 302, as shown in
The top mold 302 also includes the electric resistance wire 1002 coupled to the top of the top mold 302. The electric resistance wire 1002 is operatively coupled to and controlled by the control module 106, and receives electrical current from the electrical system of the ice making system 100. The electrical resistance wire 1002 is configured to provide heat to the ice pieces 114 within the top mold 302. After the ice pieces 114 have been formed, but before the bottom mold 304 is moved downward, the control module 106 causes the electrical resistance wire 1002 to heat briefly, such that the ice pieces 114 are loosened from the mold 302. This allows the ice pieces 114 to separate from the top mold 302 as the bottom mold 304 moves downward.

- a top mold removably coupled to a portion of the frame near the top of the sidewalls, wherein the top mold is located between the sidewalls, and wherein the top mold is oriented in a horizontal position, and configured to receive water from a water line of the automatic shaped ice system, and wherein the top mold includes a plurality of downward-facing cavities for forming shaped ice pieces;
- a bottom mold located between the sidewalls and movably coupled to each sidewall track, whereby at a top position the bottom mold is coupled to the top mold, the bottom mold including a plurality of cavities configured to form three-dimensional shapes when matched with the cavities of the top mold;
- two flanges coupled to the bottom mold, wherein each arm is coupled proximate to the sidewall, each flange generally perpendicular to a horizontal plane of the bottom mold and extending generally downward when the bottom mold is in a horizontal position, each flange including two generally parallel arms and a channel formed between the arms;
- two track plates oriented parallel to the sidewalls, each track plate pivotally coupled at one end to an inside face of the proximate sidewall by an upper bolt located proximate to the top mold, each track plate including a curved rod track;
- a cylindrical rod coupled to the bottom mold and oriented horizontally, the rod passing through each rod track and each vertical track and spanning between the sidewalls, whereby movement of the rod is constrained by the rod tracks and the vertical tracks, and wherein when the bottom mold is in the top position the rod is in a top position; and
- a pivot bolt projecting inward from each sidewall and extending through each flange channel, whereby when the rod is moved downward from the top position, the bottom mold moves downward to a bottom position, and rotates approximately 180 degrees, whereby ice pieces formed when the top mold is coupled to the bottom mold are inverted, whereby gravity causes the ice pieces to fail from the bottom mold.
18. The shaped ice unit of claim 17, wherein the plurality of cavities are configured to produce approximately the same ice shapes.
19. The shaped ice unit of claim 17, wherein the plurality of cavities are configured to produce at least two different ice shapes.
20. The shaped ice unit of claim 17, further comprising an actuator coupled to the rod, the actuator configured to move the rod between the rod top position and the rod bottom position.
