[0012] An eccentric cam is installed at the connection between the ice-making tray assembly and the water box assembly. When removing ice, the eccentric cam presses down on the sliding hinge, causing it to swing relative to the ice-making tray assembly with the ice-removing support as the fulcrum, and the water box assembly disengages from the ice-making tray assembly. At the same time, the sliding hinge reaches the ice-removing hinge state, and under the action of gravity, the water box assembly flips open with the sliding hinge as the fulcrum.

[0014] In some embodiments, multiple eccentric cams are fixed to the rotating shaft at intervals along the axial direction. The eccentric cams are misaligned with the U-shaped lugs. A drive motor is installed at one end of the rotating shaft. During de-icing, the rotating shaft drives the eccentric cams to rotate. The outer wall of the eccentric cams presses against the sliding hinge portion, causing the sliding hinge portion to swing around the de-icing support portion as a fulcrum. The hinge groove approaches and fits against the rotating shaft, thereby achieving the de-icing hinged state.

[0038] Combination Figures 1-9As shown, this utility model provides an ice-making mechanism for an ice maker, including an ice-making tray assembly 1 and a water box assembly 2 movably mounted on one side of the ice-making tray assembly 1. In this embodiment, the ice-making tray assembly 1 and the water box assembly 2 are arranged vertically, with the water box assembly 2 positioned below the ice-making tray assembly 1. Multiple first ice-making shells 11 are spaced apart along a straight line at one end of the ice-making tray assembly 1 facing the water box assembly 2, and multiple second ice-making shells 21 are spaced apart along a straight line at one end of the water box assembly 2 facing the ice-making tray assembly 1. The multiple first ice-making shells 11 and the multiple second ice-making shells 21 correspond one-to-one. When the water box assembly 2 and the ice-making tray assembly 1 are closed, the first ice-making shells 11 and the second ice-making shells 21 abut against each other and form a conductive bonding surface, which is used for heat transfer. An evaporator tube 12 is installed inside the ice-making tray assembly 1. The evaporator tube 12 is used to cool the first ice-making shell 11. When making ice, the first ice-making shell 11 can cool the second ice-making shell 21 through the conductive joint surface. That is, the heat of the second ice-making shell 21 can be conducted to the first ice-making shell 11 through the conductive joint surface, thereby reducing the temperature of the second ice-making shell 21 for cooling.

[0039] This structure employs a dual-sided cooling design. By using a first and second ice-making shell that work together, after molding, the first and second ice-making shells abut against each other to form a conductive interface. While the first ice-making shell is cooling, it also allows the second ice-making shell to cool through this conductive interface, achieving dual-sided cooling. This accelerates the freezing process, significantly improving ice-making efficiency and better meeting the needs of homes, restaurants, and other establishments for rapid ice supply. The conductive interface formed after the first and second ice-making shells are molded ensures that water is cooled evenly from both sides during the ice-making process, resulting in ice blocks with higher transparency and the formation of clear, spherical ice blocks, effectively improving ice-making quality.

[0040] In some embodiments, such as Figures 3 to 6 As shown, the first ice-forming shell 11 has a first cold conduction wall 111 protruding outward at one end facing the second ice-forming shell 21, and the second ice-forming shell 21 has a second cold conduction wall 211 adapted to the first cold conduction wall 111 at one end; when the first cold conduction wall 111 and the second cold conduction wall 211 abut against each other, a conductive bonding surface is formed. This structure, with the convex first cold conduction wall 111 and the second cold conduction wall 211 working together, has a larger conductive bonding surface area, better conduction effect, and a better cooling effect for the second ice-forming shell 21.

[0041] In some embodiments, such as Figure 5 and Figure 6As shown, the first ice-making shell 11 and the second ice-making shell 21 have the same structure, both including a hemispherical shell 212; after the first ice-making shell 11 and the second ice-making shell 21 are molded together, they can form a spherical ice-making cavity, which can produce spherical ice. The first cold conduction wall 111 and the second cold conduction wall 211 are respectively set on the corresponding hemispherical shell 212, and the two cold conduction walls and the hemispherical shells are designed as an integral structure; during manufacturing, the two ice-making shells can be formed by stamping metal plates of a certain thickness through a stamping process.

[0042] In some embodiments, such as Figure 4 As shown, a water tank assembly 2 is equipped with a water spray pipe 22, and multiple water spray nozzles 221 are spaced apart along a straight line on the water spray pipe 22. The multiple water spray nozzles 221 are connected to multiple second ice-making shells 21 in a one-to-one correspondence. During ice making, water is sprayed into the ice-making chamber through the water spray nozzles 221.

[0043] In some embodiments, such as Figures 1 to 3 As shown, one end of the water box assembly 2 is movably connected to the ice tray assembly 1 via a sliding hinge 201, and the other end of the water box assembly 2 is provided with an ice-removing support 202. The sliding hinge 201 can swing relative to the ice tray assembly 1 and reach an ice-removing hinged state with the ice tray assembly 1. After the mold is closed, the ice-removing support 202 abuts against the lower end surface of the ice tray assembly 1. An eccentric cam 3 is installed at the connection between the ice tray assembly 1 and the water box assembly 2. During ice removal, the eccentric cam 3 presses down on the sliding hinge 201, causing it to swing relative to the ice tray assembly 1 with the ice-removing support 202 as the fulcrum, and the water box assembly 2 disengages from the ice tray assembly 1. At the same time, the sliding hinge 201 reaches the ice-removing hinged state, and under the action of gravity, the water box assembly 2 flips open with the sliding hinge 201 as the fulcrum.

[0044] This structure, in the pre-ice removal stage, utilizes the principle of leverage. With the ice removal support as the fulcrum, an eccentric cam applies pressure at the sliding hinge furthest from the ice removal support. Its long lever arm allows the water tank assembly to easily detach from the ice-making tray assembly, reducing effort during ice removal and thus decreasing motor power and manufacturing costs. Once the water tank assembly detaches from the ice-making tray assembly, the sliding hinge reaches a de-ice hinged state, where it is hinged to the ice-making tray assembly. In this state, the water tank assembly, under its own weight, can rotate using the sliding hinge as a fulcrum until it is fully extended, achieving automatic extension. The entire ice removal process is seamless, simple, and convenient.

[0045] In some embodiments, such as Figure 2 and Figure 3As shown, the sliding hinge part 201 is provided with a plurality of U-shaped ears 203 at intervals along a straight line, and the U-shaped ears 203 are provided with movable grooves 204; one end of the ice-making tray assembly 1 is equipped with a rotating shaft 13, which passes through the movable groove 204, and one end of the movable groove 204 is provided with a hinge groove 205 that is adapted to the rotating shaft 13; when the rotating shaft 13 is placed in the hinge groove 205, the sliding hinge part 201 reaches the ice-removing hinge state.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, multiple eccentric cams 3 are fixed to the rotating shaft 13 at intervals along the axial direction. The eccentric cams 3 and the U-shaped lugs 203 are staggered. A drive motor (not shown in the figure) is installed at one end of the rotating shaft 13. During de-icing, the rotating shaft 13 drives the eccentric cams 3 to rotate. The outer wall of the eccentric cams 3 presses against the sliding hinge part 201, causing the sliding hinge part 201 to swing with the de-icing support part 202 as the fulcrum. The hinge groove 205 approaches and fits against the rotating shaft 13, thereby achieving the de-icing hinged state.

[0047] In some embodiments, such as Figure 3 and Figure 7 As shown, a raised shaft 206 is provided on the de-icing support 202, and an inner groove 101 adapted to the raised shaft 206 is provided at one end of the ice-making tray assembly 1; during ice making, the raised shaft 206 is placed in the inner groove 101. With this structure, the sliding hinge part rotates more smoothly with the raised shaft as the fulcrum in the front stage of de-icing, through the cooperation of the raised shaft and the inner groove for support.

[0048] In some embodiments, such as Figures 1 to 3 As shown, drive levers 5 are installed on one or both sides of the rotating shaft 13. In order to achieve more balanced force distribution, drive levers are symmetrically installed on both sides of the ice-making tray assembly in this embodiment. The drive levers 5 are connected to the water box assembly 2 through springs 4. The drive levers 5 can drive the water box assembly 2 to move closer to the ice-making tray assembly 1 through the springs 4. After the mold is closed, the drive levers 5 tension the springs 4. Under the elastic force of the springs, the water box assembly and the ice-making tray assembly can be tightly fitted together to ensure the sealing of the ice-making process.

[0049] In some embodiments, such as Figure 2 and Figure 3As shown, a drive pin 14 is fixed on the rotating shaft 13, and an arc-shaped clearance groove 501 is provided at one end of the drive rocker arm 5. The drive pin 14 is placed in the arc-shaped clearance groove 501. When the drive pin abuts against the two end walls of the arc-shaped clearance groove, the rotating shaft can drive the drive rocker arm to rotate through the drive pin. When the drive pin slides in the arc-shaped clearance groove, the rotating shaft and the drive rocker arm are not linked. A push part 502 is provided on the drive rocker arm 5. The push part 502 is used to push the water box assembly 2 to flip open with the sliding hinge part 201 as the fulcrum when de-icing. With the addition of the push part, under the drive of the rotating shaft, the thrust of the push part, combined with the gravity of the water box assembly, makes the water box assembly unfold more smoothly around the sliding hinge part.

[0050] like Figure 2 As shown, a hook rod 503 is provided at one end of the drive lever 5 away from the rotating shaft 13, and a hook post 207 is provided on one side of the water box assembly 2. One end of the spring 4 is hooked on the hook rod 503, and the other end is hooked on the hook post 207.

[0051] The ice-making mechanism is used as follows:

[0052] See Figure 4 and Figure 7 During ice making, the water box assembly and the ice making plate assembly are molded together, the protruding shaft is placed in the inner groove, and the rotating shaft is placed in the movable groove and located below the hinge groove; the drive lever tensions the spring, so that the water box assembly and the ice making plate assembly fit tightly together; the first cold conduction wall and the second cold conduction wall abut against each other to form a conduction joint surface, and the water spray nozzle sprays water into the ice making cavity; after the water is added, the evaporation tube works, and the first ice making shell and the second ice making shell cool at the same time, so that the water in the ice making cavity turns into ice cubes.

[0053] During ice removal, the drive motor rotates, which in turn drives the rotating shaft. Under the spring force, the drive rocker arm rotates a certain angle following the drive pin. As the drive motor drives the rotating shaft, the shaft drives the eccentric cam to rotate. The outer wall of the eccentric cam presses against the sliding hinge, causing the sliding hinge to swing around the ice removal support as a fulcrum. The hinge groove gradually approaches and engages with the rotating shaft. At this point, the water tank assembly disengages from the ice-making tray assembly, and the sliding hinge reaches the ice removal hinge state where it is hinged to the ice-making tray assembly (e.g., Figure 8 During this process, the drive pin slides within the arc-shaped clearance groove, causing the drive lever and the rotating shaft to not move together.

[0054] As the shaft continues to rotate, the drive pin contacts the end of the arc-shaped clearance groove, causing the drive lever to rotate towards the water tank assembly. The drive unit rests against the water tank assembly. At this time, under the combined action of the weight of the water tank assembly and the thrust of the drive unit, the water tank assembly will rotate around the sliding hinge as a support point. The protruding shaft disengages from the inner groove, and the water tank assembly gradually unfolds completely (as shown). Figure 9Once the water tank assembly unfolds, the prepared ice cubes can be de-iced by controlling the heating via a solenoid valve, and then simply wait for the ice cubes to fall off on their own.

[0055] In this specification, the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0056] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
