[0097] Please refer to Figures 1-8 The ice making device provided by the utility model can realize five ice making modes: unified cubic ice making, unified hemispherical ice making, mixed ice making (cubic + hemispherical), combined cuboid ice making and combined spherical ice making.

[0098] The first direction X and the second direction Y are parallel to the horizontal direction, and the third direction Z is parallel to the vertical direction, and the ice making process and working principle of the ice making device provided by the utility model are as follows:

[0099] If the user selects the unified ice-making mode under the single ice-making mode to make cube ice blocks (i.e., unified cube ice making), the control device controls the first and second flip motors to flip clockwise and maintain them in the default initial state, so that the first and second cube mold cavities are both flipped to the ice-making posture with the horizontal surface facing upward (the corresponding working surface is parallel to the horizontal direction and facing upward). Then, the first and second square cavity water inlets are opened to inject the required amount of water into each of the first and second cube mold cavities. After the refrigerator's refrigeration system starts working, cold air enters the freezer compartment and freezes the water, the first and second flip motors are flipped 180 degrees counterclockwise, so that the first and second cube mold cavities are both flipped to the demolding posture with the horizontal surface facing downward (the corresponding working surface is parallel to the horizontal direction and facing upward). After demolding is completed, the first and second flip motors flip clockwise and reset to maintain the initial state.

[0100] If the user selects the unified ice-making mode under the single ice-making mode to make hemispherical ice blocks (i.e., unified hemispherical ice making), the first and second flip motors are controlled to flip 180 degrees forward from the initial state (or after flipping to the initial state) so that the first and second hemispherical mold cavities are both flipped to the horizontal upward ice-making posture. Then, the water inlets of the first and second spherical cavities are opened to inject the required amount of water into each of the first and second hemispherical mold cavities. After the water is frozen, the first and second flip motors are flipped 180 degrees in the opposite direction so that the first and second hemispherical mold cavities are both flipped to the horizontal downward demolding posture. After demolding is completed, the first and second flip motors are flipped forward again and reset to maintain the initial state.

[0101] If the user selects the mixed ice-making mode under the single ice-making mode to make hemispherical + cubic ice blocks (i.e., mixed ice making of cubes + hemispheres), the first flip motor is controlled to flip back to the initial state, and the second flip motor is controlled to flip forward 180 degrees from the initial state (or after flipping back to the initial state), so that the first cubic mold cavity and the second hemispherical mold cavity are both flipped to the horizontal upward ice-making posture. Then, the water inlet of the first cubic cavity and the water inlet of the second spherical cavity are opened to inject the required amount of water into each of the first cubic mold cavity and the second hemispherical mold cavity. After the water is frozen, the first flip motor and the second flip motor are respectively flipped in the opposite direction by 180 degrees, so that the first cubic mold cavity and the second hemispherical mold cavity are both flipped to the horizontal downward demolding posture. After demolding is completed, the first flip motor and the second flip motor are respectively flipped forward and reset to maintain the initial state.

[0102] If the user chooses to make cuboid ice blocks in the combined ice-making mode (i.e., combined cuboid ice making), the first and second flip motors are controlled to flip 90 degrees in the opposite direction and 90 degrees in the forward direction respectively in the initial state (or after flipping to the initial state), so that the corresponding first working surfaces 411 of the first and second ice-making molds 4 are adjusted to be parallel to the third direction Z (vertical direction). At this time, the first and second cube mold cavities of the first and second ice-making molds 4 are adjusted to a parallel docking posture.

[0103] Subsequently, the first drive motor (first drive unit 21) starts to rotate forward, driving a pair of driven racks (linear motion components 22) to move towards each other (centripetally) along a pair of rack guide rails 5 and a pair of support guide rails (guide structure 6), thereby pushing a pair of flipping drive devices 3 to drive the first ice mold 4 and the second ice mold 4 to move towards each other (centripetally) along the support guide rails (guide structure 6) until the corresponding first working surfaces 411 of the first ice mold 4 and the second ice mold 4 are in close contact and closed, connecting and sealing each first cubic mold cavity and the second cubic mold cavity into a complete cuboid cavity.

[0104] Then, the first square cavity water inlet and the second square cavity water inlet are opened to inject the required amount of water into each of the first cube mold cavity and the second cube mold cavity respectively. After the water is frozen, the first drive motor (first drive unit 21) starts to reverse until the first ice mold 4 and the second ice mold 4 move back to back (vest) to the distance of the initial state. The first flip motor and the second flip motor flip 90 degrees forward and 90 degrees backward respectively, so that the first cube mold cavity and the second cube mold cavity are flipped to the horizontal demolding posture. After demolding is completed, the first flip motor and the second flip motor flip 180 degrees backward respectively and reset to maintain the initial state.

[0105] If the user chooses to make spherical ice blocks in the combined ice-making mode (i.e., combined spherical ice making), the first and second flip motors are controlled to flip 90 degrees forward and 90 degrees backward respectively in the initial state (or after flipping to the initial state), so that the corresponding second working surfaces 412 of the first and second hemispherical mold cavities of the first and second ice-making mold 4 are adjusted to be parallel to the third direction Z (vertical direction). At this time, the first and second hemispherical mold cavities of the first and second ice-making mold 4 are adjusted to a parallel docking posture.

[0106] Subsequently, the first drive motor (first drive unit 21) starts to rotate forward, driving a pair of driven racks (linear motion components 22) to move towards each other (centripetally) along a pair of rack guide rails 5 and a pair of support guide rails (guide structure 6), thereby pushing a pair of flipping drive devices 3 to drive the first ice mold 4 and the second ice mold 4 to move towards each other (centripetally) along the support guide rails (guide structure 6) until the corresponding second working surfaces 412 of the first ice mold 4 and the second ice mold 4 are in close contact and closed, connecting and sealing each of the first hemispherical mold cavity and the second hemispherical mold cavity into a complete spherical cavity.

[0107] Then, the first and second ball cavity water inlets are opened to inject the required amount of water into each of the first and second hemispherical mold cavities. After the water is frozen, the first drive motor (first drive unit 21) starts to reverse until the first ice mold 4 and the second ice mold 4 move back and forth (vest) to the distance in the initial state. The first and second flip motors are then flipped 90 degrees in the opposite direction and 90 degrees in the forward direction, respectively, so that the first and second hemispherical mold cavities are flipped to the horizontal demolding posture. After demolding is completed, the first and second flip motors are flipped 180 degrees in the opposite direction and reset to maintain the initial state.

[0108] Therefore, this ice-making device uses two double-sided ice-making molds to achieve five ice-making modes and four ice shapes. It has a simple structure, rich functions, and stable operation, and has good industrialization promotion value and market application prospects.

[0109] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Those skilled in the art should understand that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
