[0045] In related technologies, ice-making functionality has become a standard feature in overseas refrigerator products. One type of refrigerator with ice-making functionality houses the ice maker in the refrigerator compartment, with ice dispensing via the refrigerator door. This type of refrigerator typically has an upper refrigerator compartment and a lower freezer compartment, with a separate ice-making space within the refrigerator compartment. To save space, the ice-making and ice-storage systems are placed at the bottom of the refrigerator compartment. To further reduce the space required for the ice-storage system, the ice storage box is located at the bottom. When ice blocks are ejected from the ice storage box, they need to be lifted a certain distance into the ice-crushing chamber. However, existing ice-lifting mechanisms suffer from unstable transmission and poor stability during the ice-lifting process.

[0046] This application provides an ice block lifting mechanism, an ice-making system, and a refrigerator to solve the problem of poor transmission stability in existing ice block lifting mechanisms. The following will be discussed in conjunction with the accompanying drawings. Figure 1-9 Please provide an explanation.

[0047] The ice lifting mechanism provided in this application embodiment is referenced. Figure 1 , Figure 2 and Figure 3 As shown, the device includes an ice conveying box 100, a screw 200, a driving member 300, and a driven member 400. The ice conveying box 100 forms an ice conveying cavity 110 and an ice inlet 120 and an ice outlet 130 communicating with the ice conveying cavity 110. The screw 200 is disposed in the ice conveying cavity 110. The driving member 300 and the driven member 400 are respectively connected to the two ends of the screw 200. Both the driving member 300 and the driven member 400 are rotatably mounted on the ice conveying box 100, and the driving member 300 is used to connect with the driving member to drive the screw 200 to rotate.

[0048] It is understood that in this embodiment, the ice inlet 120 of the ice conveying chamber 110 can be connected to the ice storage box of the ice maker. The ice blocks in the ice storage box enter the ice conveying chamber 110 through the ice inlet 120. The screw 200 extends along the height direction of the ice conveying chamber 110. The ice blocks are gradually lifted upward under the drive of the screw 200 and discharged from the ice outlet 130. The ice outlet 130 can be connected to the ice crusher. The ice crusher can be equipped with an ice blade assembly. During the rotation of the ice blade assembly, the whole ice is chopped into crushed ice, realizing the switching of the ice making system between the whole ice dispensing mode and the crushed ice dispensing mode.

[0049] For example, the cross-sectional shape of the ice container 100 may include, but is not limited to, a circle, a square or other shapes, and this embodiment does not specifically limit it.

[0050] In this embodiment, the driving member 300 and the driven member 400 are respectively fixed to both ends of the screw 200, ensuring that the screw 200 is centered within the ice conveying cavity 110. Both the driving member 300 and the driven member 400 are rotatably mounted to the ice conveying box 100, allowing the screw 200 to rotate freely within the ice conveying cavity 110 without contacting the sidewall. The driving member 300 is connected to an external drive component (such as a motor) to receive power and drive the screw 200 to rotate. The driven member 400 rotates with the screw 200, providing support and stability to the screw 200.

[0051] By setting the driving element 300 and the driven element 400 at both ends of the screw 200 and rotatably installing them on the ice conveying box 100, the screw 200 is precisely positioned in the middle of the ice conveying cavity 110, avoiding collision with the side wall, improving the stability of the transmission, and ensuring the uniformity of the rotation of the screw 200, so that the ice block can be smoothly and efficiently lifted to the ice outlet 130.

[0052] In one alternative implementation, refer to Figure 2 and Figure 5 As shown, the ice box 100 has a first mounting hole 140, and the active member 300 is provided with a mounting part 301, which passes through the first mounting hole 140.

[0053] In this embodiment, the active member 300 is provided with a mounting part 301. The mounting part 301 can be a mounting protrusion that cooperates with the first mounting hole 140. Its shape and size are adapted to the first mounting hole 140. It is used to fix the position of the active member 300 on the ice conveying box 100, reduce the possible displacement during the movement of ice blocks, and ensure the stability of the transmission.

[0054] In one alternative implementation, refer to Figure 2 and Figure 5 As shown, the active component 300 is provided with an abutment part 310. When the active component 300 is installed on the ice conveying box 100, the abutment part 310 abuts against the ice conveying box 100.

[0055] For example, the abutment portion 310 can be a stepped structure as shown in the figure. When the active component 300 is installed into the ice conveying box 100, the abutment portion 310 contacts other structural parts of the end face of the ice conveying box 100, which plays a limiting role, preventing the active component 300 from moving excessively or falling off. The abutment portion 310 is also conducive to accurately positioning the active component 300, ensuring the correct cooperation between the active component 300 and other components, improving installation accuracy, and effectively preventing the active component 300 from shaking during the ice lifting process, thereby improving the operational stability of the ice lifting mechanism.

[0056] In one alternative implementation, refer to Figure 3 and Figure 4 As shown, the active member 300 has an annular first mounting groove 320, and the screw 200 is wound in the first mounting groove 320; and a second mounting groove 330 is provided in the middle of the first mounting groove 320, that is, the first mounting groove 320 is arranged around the outside of the second mounting groove 330, the second mounting groove 330 is provided with a notch 331, and one end of the screw 200 passes through the notch 331 and is located in the second mounting groove 330.

[0057] In this embodiment, an annular first mounting groove 320 is formed on the driving member 300 for winding the screw 200, increasing the contact area between the screw 200 and the driving member 300, thereby improving the connection stability between the screw 200 and the driving member 300. Simultaneously, one end of the screw 200 passes through the notch 331 and is located in the second mounting groove 330 in the middle of the first mounting groove 320, ensuring accurate and fixed positioning of the screw 200 and convenient installation. When the driving member (such as a motor) drives the driving member 300 to rotate, since one end of the screw 200 passes through the notch 331 and is fixed in the second mounting groove 330, the rotation of the driving member 300 can be effectively transmitted to the screw 200. The rotation of the screw 200 then pushes the ice blocks in the ice box 100 upwards along the spiral trajectory of the screw 200.

[0058] In one alternative implementation, refer to Figure 4 and Figure 5 As shown, the first mounting groove 320 is provided with a plurality of spaced-apart snap-fit ​​parts 332 along the circumferential direction, and the screw 200 snaps into the snap-fit ​​parts 332.

[0059] In this embodiment, the first mounting groove 320 is provided with a plurality of spaced-apart locking portions 332 along its circumference. These locking portions 332 can be evenly or unevenly distributed within the first mounting groove 320. Their function is to ensure that the screw 200 can be tightly engaged with these locking portions 332 during installation, thereby providing support and positioning. When the screw 200 is installed onto the driving member 300, the helical portion of the screw 200 interacts with the locking portions 332 within the first mounting groove 320. Each locking portion 332 can engage a corresponding part of the screw 200, ensuring that the screw 200 does not move axially or radially during rotation. This improves the connection stability between the screw 200 and the driving member 300, ensures the precise position of the screw 200 during rotation, and enhances the transmission stability of the screw 200 during ice lifting.

[0060] In one alternative implementation, refer to Figure 6 As shown, the follower 400 has an annular third mounting groove 410, and the other end of the screw 200 is wound in the third mounting groove 410.

[0061] For example, the connection between the screw 200 and the driven member 400 can be similar to that of the driving member 300. An annular third mounting groove 410 is formed on the driven member 400. The shape and size of the third mounting groove 410 are designed to cooperate with the other end of the screw 200, receive and fix the other end of the screw 200, thereby realizing the power transmission between the driven member 400 and the driving member 300. The spiral winding method improves the connection stability between the screw 200 and the driven member 400.

[0062] In one alternative implementation, refer to Figure 2 and Figure 7 As shown, the bottom of the ice container 100 is provided with a mounting post 150, and the driven member 400 is provided with a second mounting hole 420, through which the mounting post 150 passes. The mounting post 150 can be cylindrical, and its size is adapted to the second mounting hole 420. Through the connection of the mounting post 150 and the second mounting hole 420, the driven member 400 is more firmly fixed on the ice container 100, reducing shaking during movement and improving overall stability. Furthermore, the connection design of the mounting post 150 and the third mounting hole simplifies the connection process between the ice container 100 and the driven member 400, making installation and subsequent maintenance more convenient.

[0063] In one alternative implementation, refer to Figure 8 As shown, the ice block lifting mechanism also includes a first baffle 500, which extends along the height direction of the screw 200 and is sleeved inside the screw 200 to guide the ice block to move along the first baffle 500.

[0064] The first baffle 500 is fitted inside the screw 200 to prevent ice from accumulating inside the spiral screw 200, which would prevent the ice from being lifted effectively. This reduces the need for manual cleaning due to ice getting stuck on the screw 200, reduces maintenance workload, improves the overall stability and reliability of the ice lifting mechanism, and reduces the failure rate caused by ice accumulation.

[0065] In one alternative implementation, refer to Figure 8 As shown, the ice lifting mechanism also includes a second baffle 600, which extends along the height direction of the screw 200 and is disposed on the outside of the screw 200 or the inner wall of the ice conveying box 100 to guide the ice blocks to move along the second baffle 600.

[0066] The second baffle 600 is disposed on the outside of the screw 200 or on the inner wall of the ice conveying box 100, which can effectively limit the lateral movement of the ice block during the lifting process and ensure that the ice block rises along the predetermined path. When the second baffle 600 is disposed on the inner wall of the ice conveying cavity 110, the design of the ice conveying box 100 can be made more compact, and the space utilization rate inside the ice conveying cavity 110 can be improved.

[0067] The design of the first baffle 500 and the second baffle 600 ensures that the ice blocks move in a straight line along the height direction within the ice conveying chamber 110, preventing lateral deviation of the ice blocks during the lifting process, avoiding the complexity of the traditional spiral path, reducing unnecessary movement paths, and thus speeding up the ice discharge speed.

[0068] In one alternative implementation, refer to Figure 8 As shown, the bottom of the ice feeding box 100 is provided with an ice crushing port 160, and the ice feeding box 100 is provided with an ice crushing box 700 below it, with the ice crushing box 700 corresponding to the ice crushing port 160.

[0069] Understandably, during the ice lifting process, the ice lifting mechanism may generate ice shards or small ice pieces due to collisions between the ice block and the screw 200, between ice blocks, and between the ice block and the inner wall of the ice conveying box 100. The accumulation of ice shards in the ice conveying chamber 110 can easily cause blockage and affect the ice dispensing efficiency. The bottom of the ice conveying box 100 is provided with an ice crushing port 160. The design of the ice crushing port 160 allows ice shards to be discharged in a timely manner, preventing blockage during the ice lifting process, thereby ensuring that the ice blocks are smoothly delivered to the ice outlet 130.

[0070] Furthermore, by separating ice blocks and ice shards, it ensures that the ice blocks received by the end user are intact and free of fragments, thus improving the user experience. Below the ice delivery box 100 is an ice crushing box 700, which corresponds to the ice crushing opening 160. Ice shards falling from the ice crushing opening 160 can enter the ice crushing box 700 for storage. The design of the ice crushing box 700 makes collecting and cleaning ice shards simple and convenient, reducing the frequency and difficulty of user maintenance of the ice delivery box 100, and facilitating cleaning and maintenance.

[0071] For example, the size, shape, and number of the ice crushing openings 160 can be configured as needed to ensure that ice shavings can pass through smoothly without clogging, while also preventing large ice chunks from falling into the ice crushing box 700. For instance, there can be multiple ice crushing openings 160, and these openings can be spaced circumferentially along the ice conveying box 100 to ensure that ice shavings can be fully discharged into the ice crushing box 700.

[0072] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, the active component 300 is rotatably disposed on the top of the ice conveying box 100, and the driven component 400 is rotatably disposed on the bottom of the ice conveying box 100. This allows the driving component connected to the active component 300 to be disposed above the ice conveying box 100, avoiding interference with the ice crushing box 700 at the bottom. This makes the overall structure of the ice lifting mechanism more compact and improves the overall space utilization efficiency.

[0073] In one alternative implementation, refer to Figure 7 As shown, the ice crusher 700 is provided with a handle, and the ice crusher 700 is slidably disposed on the ice conveyor 100.

[0074] In this embodiment, the ice crusher 700 is provided with a handle, making it easy for users to remove and put back the ice crusher 700, thus improving operational convenience. The ice crusher 700 is designed to slide within the ice conveyor 100; for example, the bottom of the ice conveyor 100 is provided with a sliding track or guide rail to ensure that the ice crusher 700 can slide smoothly. The sliding design of the ice crusher 700 allows users to easily remove the ice crusher 700 when needed for cleaning or emptying the crushed ice, preventing ice accumulation and further improving operational convenience.

[0075] The ice lifting mechanism provided in this embodiment includes an ice conveying box 100, a screw 200, a driving member 300, and a driven member 400. The ice conveying box 100 has an ice conveying cavity 110 and an ice inlet 120 and an ice outlet 130 communicating with the ice conveying cavity 110. The screw 200 is disposed inside the ice conveying cavity 110.

[0076] The driving component 300 and the driven component 400 are respectively connected to both ends of the screw 200. Both the driving component 300 and the driven component 400 are rotatably mounted on the ice conveying box 100. The driving component 300 is used to connect with the driving component to drive the screw 200 to rotate. By setting the driving component 300 and the driven component 400 at both ends of the screw 200 and rotatably mounting the driving component 300 and the driven component 400 on the ice conveying box 100, the screw 200 can be positioned in the middle of the ice conveying cavity 110, avoiding collision between the screw 200 and the side wall of the ice lifting cavity during the rotation process. This enhances the transmission stability during the ice lifting process and achieves stable lifting of the ice.

[0077] Secondly, embodiments of this application also provide an ice-making system, combined with Figure 1 and Figure 9 As shown, the ice-making system includes an ice-lifting mechanism as described in the above embodiment.

[0078] For example, the ice-making system may include an ice maker, an ice lifting mechanism, and an ice crusher. The ice inlet 120 of the ice lifting mechanism is connected to the ice maker, and the ice outlet 130 of the ice lifting mechanism is connected to the ice crusher. The ice obtained from the ice maker can be lifted by the ice lifting mechanism and enter the ice crusher. The lifted ice can be directly taken by the user or further processed into crushed ice by the ice crusher, thereby automating the ice-making process, reducing manual operation by the user, improving the smoothness and efficiency of ice dispensing, and making the entire ice-making process more convenient and efficient.

[0079] Thirdly, embodiments of this application also provide a refrigerator, which includes an ice-lifting mechanism or an ice-making system as described in the above embodiments.

[0080] It is understood that the refrigerator in this embodiment may include, but is not limited to, single-door refrigerators and double-door refrigerators. The refrigerator includes a refrigerator compartment and a freezer compartment. The ice-making system may be located at the bottom of the refrigerator compartment, and the ice outlet of the ice-making system may be located on the refrigerator door.

[0081] It is understood that since the ice lifting mechanism and ice making system have the beneficial effects of the above embodiments, the refrigerator will have the beneficial effects of the above embodiments accordingly. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat it.
