[0055] A refrigerator according to a preferred embodiment of the present invention mainly includes a refrigerator body and an ice maker.

[0056] The box may define a refrigerator compartment and a freezer compartment. In actual configuration, the ice maker may be located directly in the freezer compartment, in which case the freezer compartment serves as the ice-making chamber. Alternatively, a separate ice-making chamber may be defined within the refrigerator compartment or the freezer compartment by insulating panels, with the ice maker located within the ice-making chamber.

[0057] See also Figure 1 The ice maker includes a base 100 , a shell 200 , a mold 300 and a driving mechanism 500 .

[0058] See also Figure 2The base 100 is used to connect with the ice making chamber, and specifically includes an upper side plate 101, a left side plate 102, a right side plate 103, a front side plate 104 and a rear side plate. The front, rear, left and right directions mentioned in this application are defined for the purpose of clearly describing the structure. In actual settings, they are not limited to the front, rear, left and right directions. Figure 2 The front-to-back direction is shown within the ice making chamber.

[0059] See also Figure 4 The housing 200 includes a first housing portion 210 and a second housing portion 220. The inner wall of the first housing portion 210 is provided with a first inner cavity, and the inner wall of the second housing portion 220 is provided with a second inner cavity. The first housing portion 210 and the second housing portion 220 can be opened and closed and enclose an inner cavity when closed.

[0060] See also Figure 4 The mold body 300 is arranged in the inner cavity, and the mold body 300 includes a first mold part 310 and a second mold part 320. The first mold part 310 is attached to the first inner cavity of the first shell part 210, has a first concave cavity, and can move with the first shell part 210. The second mold part 320 is attached to the second inner cavity of the second shell part 220, has a second concave cavity, and can be fixed with the second shell part 220. The first mold part 310 and the second mold part 320 form a mold cavity when closed. The shape of the mold cavity is the shape of the ice cube produced. The mold cavity can be designed according to the needs of the user, and can be designed into a sphere, a diamond-faced sphere or a polyhedron, etc. In addition, the first mold part 310 and the second mold part 320 are both made of food-grade silicone material that can be deformed under the action of external force.

[0061] See also Figure 4 The mold body 300 has a water inlet 301 connected to the mold cavity. The top of the first mold part 310 is provided with a first opening 311, and the top of the second mold part 320 is provided with a second opening 321. The water inlet 301 is formed when the first opening 311 and the second opening 312 are closed. An opening is provided at a position corresponding to the water inlet 301 on the upper side plate 101, and an external water pipe injects water into the mold cavity through the water inlet 301. Figure 4 and Figure 11 Corresponding to two forms of water inlet 301, Figure 4 Shown is a water inlet 301 in a closed-mold form. Figure 11 The introduction is expanded below.

[0062] See also Figure 4 The first shell portion 210 is provided with a first slot 211 , and the second shell portion 220 is provided with a second slot 221 . When the first slot 211 and the second slot 221 are closed, they form an escape opening enclosed at the periphery of the water inlet 301 .

[0063] See also Figure 1-4A first push rod 410 is provided at a predetermined distance on the back side of the first shell 210. The first push rod 410 can be fixed to the left side plate 102. A first through hole 212 is provided on the back of the first shell 210. A second push rod 420 is provided on the back side of the second shell 220. A second through hole 222 is provided on the back of the second shell 220.

[0064] The drive mechanism 500 is used to drive the first housing 210 to move, forming an opening and closing relationship with the stationary second housing 220. The first mold 310 moves with the first housing 210, while the second mold 320 remains stationary following the second housing 220. The first ejector rod 410 is stationary, while the second ejector rod 420 is linked to the first housing 210 via a connecting rod assembly 700. Figure 2 and Figure 3 1 and 2 are structural schematic diagrams of the first shell portion 210 and the second shell portion 220 in the closed and separated states respectively.

[0065] During demolding, the drive mechanism 500 drives the first shell 210 to a predetermined position. The first push rod 410 passes through the first through-hole 212 and pushes against the first mold 310, causing the first mold 310 to deform. Simultaneously, the first shell 210 drives the second push rod 420 through the connecting rod assembly 700, which passes through the second through-hole 222 and pushes against the second mold 320, causing the second mold 320 to deform. During the actual ice-making process, when the first shell 210 and the second shell 220 are separated, ice cubes may adhere to the first mold 310 or the second mold 320. The solution of the present application can eject ice cubes, regardless of whether they are in the first mold 310 or the second mold 320, causing them to fall into the ice storage bin for user access.

[0066] The present application proposes a refrigerator in which the ice-making compartment of the ice-making machine includes an openable first mold shell (first shell portion 210 and first mold portion 310) and a second mold shell (second shell portion 220 and second mold portion 320). The refrigerator is suitable for producing ice cubes of special shapes that require molds to form, such as spherical ice cubes or polyhedral ice cubes. In addition, the first mold shell is movable and has a fixed first ejector rod 410 on its back side, while the second mold shell is fixed and has a second ejector rod 420 on its back side that is linked to the first mold shell. During demolding, the first mold shell moves to a predetermined position, and the ejector rods on both sides can eject the ice cubes regardless of which mold shell is located. The demolding structure of the present application is simple and the demolding effect is reliable.

[0067] In some embodiments of the present application, the opening and closing movements of the first shell 210 and the second shell 220 may include at least translation or rotation. The present application provides preferred supporting drive mechanisms 500 for these two modes respectively.

[0068] See also Figure 1-5When the first shell 210 adopts a translational opening and closing motion, the driving mechanism 500 may include a main motor 510, a main shaft 520, a gear set 530, a rack 540 and a sliding rod 550.

[0069] See also Figure 5 Two racks 540 are provided, one located at the front and rear sides of the top of the first housing 210. Four slide bars 570 are provided, one extending through the four corners of the first and second housings 210 and 220. The main motor 510 is connected to the main shaft 520, and the racks 540 mesh with the main shaft 520 via a gear set 530, allowing the first housing 210 to translate along the slide bars 550.

[0070] See also Figure 1-5 When the first shell 210 adopts a translational opening and closing motion, the connecting rod assembly 700 includes a connecting rod 710, a first clamping portion 720, and a second clamping portion 730. The shape of the connecting rod 710 is consistent with the motion path of the first shell 210, that is, a straight line. A fixing hole is provided on one end of the connecting rod 710, and the other end is connected to the second top rod 420. The connecting rod 710 is also provided with a strip hole 701. The first clamping portion 720 is provided on the front side and the rear side of the first shell 210, and the second clamping portion 730 is provided on the front side and the rear side of the second shell 220. The fixing hole is fixedly connected to the first clamping portion 720, and the strip hole 701 can translate left and right along the second clamping portion 730.

[0071] See also Figure 6-9 When the first housing 210 is configured to open and close using a rotational motion, the drive mechanism 500 may include a motor 501 and a rotating shaft 502. The first housing 210 is connected to the rotating shaft 502, and the motor 501 is connected to the rotating shaft 502, allowing the first housing 210 to rotate in a predetermined direction. The second housing 220 may be connected to a fixed shaft 503 or directly fixedly connected to the base 100.

[0072] See also Figure 6-9 When the first shell 210 adopts a rotational opening and closing motion, the shape of the connecting rod assembly 700 is consistent with the movement path of the first shell 210, that is, it is an arc shape, one end of which is connected to the first shell 210 by a screw, and the other end is connected to the second push rod 420.

[0073] In some embodiments of this application, see Figure 2 and Figure 7 The end face of the first push rod 410 matches the contour surface of the first mold part 310, and the end face of the second push rod 420 matches the contour surface of the second mold part 320, so that the push rod can be pushed against the mold part more closely, causing the mold part to be effectively deformed, thereby demolding the ice cubes in the mold part.

[0074] In some embodiments of this application, see Figure 10The mold body can have multiple mold cavities. The figure shows an example with three mold cavities, each of which has a water inlet 301. A water tank 600 is provided above the shell. The water tank 600 has water diversion ports 601 corresponding to the water inlets 301. A water diversion pipe can be extended from the water diversion port 601 to communicate with the water inlet 301. Figure 1 The water tank 600 can be fixed to the base 100, and an opening is provided at a position on the upper side plate 101 corresponding to the water tank 600. The multi-cavity configuration increases the ice production capacity of the ice maker. The water tank 600 with a water diversion port 601 can help improve water injection efficiency, thereby effectively improving ice making efficiency.

[0075] In some embodiments of this application, see Figure 11 A plurality of mold cavities are connected by water holes 302, so that the water injected into the mold cavity can flow in the mold cavity, thereby making the amount of water in each mold cavity tend to be even, ensuring that the weight difference of the ice cubes produced is small.

[0076] In some embodiments of this application, see Figure 11 The water inlet 301 is annular, preferably funnel-shaped, and is formed on the first mold part 310 or the second mold part 320. The present application changes the water inlet 301 from a two-half mold method to a form formed separately on one of the mold parts, which can prevent water from leaking out of the mold cavity from the mold line of the water inlet 301 during water injection, causing mold adhesion, and making it difficult to separate the first mold part 310 and the second mold part 320 during subsequent demolding, resulting in an unsmooth demolding process. In addition, since the single water injection volume during ice making is constant, if water leaks during water injection, the amount of water entering the mold cavity is reduced, the ice cubes produced are smaller than the preset value, and the integrity of the ice cubes is reduced. The use of the annular water inlet 301 of the present application can avoid water leakage, thereby better ensuring the integrity of the ice cubes.

[0077] In some embodiments of this application, see Figure 11 The first mold section 310 has a first engaging portion (not shown) at the edge of its concave cavity (the first concave cavity). The second mold section 320 has a second engaging portion 322 at its edge that mates with the first engaging portion. One of the first and second engaging portions 322 is a rib, and the other is a groove. This arrangement improves the mold fit between the first and second mold sections 310, 320, effectively preventing the ice cube from forming an irregular shape at the parting line, which could affect its aesthetic appearance.

[0078] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
