[0159] For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0160] Please refer to Figure 1 and combine with Figure 8, a refrigerator of the preferred embodiment of the present application embodiment, including the box, refrigeration cycle pipe 200, ice making room shell 300, and refrigeration pipe assembly. In some embodiments, the refrigerator also includes an ice making unit.

[0161] The cabinet comprises an outer shell and a tank arranged inside the outer shell, and a refrigeration chamber 11 is formed inside the tank.

[0162] An installation space is formed between the outer shell and the tank for installing other component structures of the refrigerator and forming a foamed thermal insulation layer. The refrigeration chamber 11 formed inside the tank is a refrigeration chamber, a variable-temperature chamber or a freezing chamber.

[0163] A refrigeration cycle pipeline 200 is arranged inside the cabinet, at least a part of which is located between the outer shell and the tank and is used for heat exchange of the refrigeration chamber 11. Referring to FIG. 9, at least a part of the refrigeration cycle pipeline 200 extends into the refrigeration chamber 11 and is denoted as a reserved section 2100.

[0164] In the embodiment, at least a part of the refrigeration cycle pipeline 200 located between the outer shell and the tank is arranged in the foamed thermal insulation layer.

[0165] The refrigerator is generally provided with a refrigeration cycle system to realize that the temperature of the refrigeration chamber 11 is lower than the ambient temperature of the refrigerator.

[0166] The refrigeration cycle system generally comprises a compressor, a condenser, a drying filter, a capillary tube and an evaporator and the like which are connected through the refrigeration cycle pipeline 200. The working constitution of the refrigeration cycle system comprises a compression process, a condensation process, a throttling process and an evaporation process. Specifically, the compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are connected, the compressor starts to work, low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor and then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas is cooled through the condenser, the temperature continuously decreases, and the refrigerant is gradually cooled into saturated vapor at normal temperature and high pressure, and further cooled into saturated liquid, the temperature no longer decreases, and the pressure of the refrigerant in the entire condensation process is almost unchanged. The throttling process is as follows: the saturated liquid refrigerant after condensation flows into the capillary tube after filtering out water and impurities through the drying filter, and the pressure is reduced through the capillary tube, and the refrigerant becomes wet vapor at normal temperature and low pressure. The evaporation process is as follows: the wet vapor at normal temperature and low pressure enters the evaporator, starts to absorb heat to vaporize, reduces the temperature of the evaporator and its surrounding, realizes refrigeration of the refrigeration chamber 11, and makes the refrigerant into low-temperature and low-pressure gas. The refrigerant from the evaporator returns to the compressor again to repeat the above process, energy conversion is realized through the state change of the refrigerant, heat in the refrigerator is transferred to air outside the cabinet, and thus the refrigeration cycle of the refrigerator is realized. The structure and operation principle of the above refrigeration cycle system of the refrigerator are related technologies, and thus will not be described herein.

[0167] In some embodiments, a more flexible temperature zone regulation scheme can be designed to allow different areas (e.g., refrigeration chamber, freezer chamber, variable temperature chamber, etc.) to be controlled by an adjustable temperature control system within the same refrigeration chamber 11, thereby improving energy efficiency and use convenience. For example, through the temperature control system and partition design, an adjustable partition is provided between the refrigeration chamber and the freezer chamber, which not only saves energy but also provides a more refined temperature control experience. The refrigeration chamber 11 can not only serve as a conventional refrigeration and freezing space, but also be designed as a multifunctional chamber. For example, through internal partitioning and temperature control systems, it can be divided into different temperature zones, such as a quick-freezing zone, a beverage zone, or a vegetable and fruit dedicated zone, etc., which not only improves space utilization, but also meets more refined storage needs. The insulation layer of the refrigeration chamber can be further optimized. For example, high-efficiency insulation materials (such as vacuum insulation panels, polyurethane foaming materials, etc.) are used to reduce heat conduction and reduce the energy consumption of the refrigeration system, thereby improving the energy efficiency ratio of the refrigerator.

[0168] In some embodiments, the design of the reserved section 2100 can be further optimized to have more adaptive functions. For example, it can be designed as a telescopic or adjustable pipe section to be more flexible during later installation or maintenance, reduce manual intervention, and improve the maintainability of the system. The reserved section can serve as a convenient interface for pipe repair and replacement, equipped with quick connection and disconnection devices, to reduce downtime caused by pipe blockage or damage, making the maintenance of the refrigerator more convenient. The reserved section can also integrate other functional modules, such as refrigerant sensors, temperature monitoring devices, or pressure sensors, to provide real-time data feedback for users or maintenance personnel to monitor the system operation status and timely detect problems and make adjustments.

[0169] Please refer to FIG. 2 and FIG. 4, the ice-making chamber shell 300 is arranged in the refrigeration chamber 11, and a first opening 310 in communication with the interior of the ice-making chamber shell 300 is arranged on the surface of the ice-making chamber shell 300.

[0170] The ice-making unit is arranged in the ice-making chamber shell 300. The ice-making unit is used to produce ice blocks, and the ice-making chamber shell 300 defines an ice-making chamber which is separated from the refrigeration chamber 11.

[0171] The refrigeration pipe assembly includes a refrigeration pipe 400 and a shell 500.

[0172] At least a part of the refrigeration pipe 400 extends into the ice-making chamber shell 300 from the first opening 310.

[0173] The refrigeration pipe 400 enters the ice-making chamber shell 300 to cool the interior of the ice-making chamber shell 300, and provides conditions for the ice-making unit to produce and store ice blocks.

[0174] In some embodiments, since the refrigeration pipe 400 can lower the temperature inside the ice-making chamber shell 300, the ice-making chamber shell 300 can be arranged in a refrigeration chamber or a freezing chamber.

[0175] The ice-making unit inside the ice-making chamber shell 300 is provided with ice trays, and a water pipe is arranged to supply water to the ice trays. The refrigeration pipe 400 exchanges heat with the ice trays. After the water in the ice trays freezes, the driving device drives the ice trays to flip over so that the openings of the ice trays face downward and the ice-making operation is performed. An ice storage box is usually arranged below the ice trays. The ice falling from the ice trays is stored in the ice storage box. The refrigeration pipe 400 exchanges heat with the air inside the ice-making chamber shell 300, which can also ensure a low-temperature state in the ice storage box. Thereafter, the ice trays are reset, the water pipe supplies water to the ice trays, and the ice-making process is repeated.

[0176] In some embodiments, in order to improve the refrigeration efficiency, the refrigeration pipe 400 can adopt a more efficient heat exchange mode. For example, a pipe with fins or a corrugated structure is adopted to increase the surface area of the refrigeration pipe and improve the heat exchange efficiency with the air or the ice-making chamber shell 300, thereby accelerating the ice-making process and improving the energy efficiency. The ice-making chamber shell 300 can be designed as a module with an independent temperature control system. For example, a small temperature controller or a temperature sensor is built-in to realize independent temperature adjustment with the refrigeration chamber or the freezing chamber, so that the ice-making process is more accurate, and the temperature conditions for ice production can be adjusted according to actual needs, thereby optimizing the ice-making efficiency and quality. In the design of the refrigeration pipe 400, a flow control device such as an electronic expansion valve can be added to adjust the refrigerant flow according to the ice-making demand, thereby optimizing the refrigeration performance of the system. The refrigerant flow can be dynamically adjusted according to the ice-making demand (such as ice production) to avoid excessive refrigeration or energy waste. During the ice-making process, condensate water may be generated in the refrigeration pipe 400 and the ice-making chamber shell 300. A condensate water collection and discharge system can be designed to avoid water accumulation in the ice-making chamber or other components, which affects the ice quality or the normal operation of the refrigerator. In addition to the conventional ice production, the ice-making system can also support other functions such as filtered ice water, ice crushing function of ice cubes, and even provide ice slush function, etc.

[0177] Please refer to FIG. 5, in combination with FIG. 4, the shell 500 is detachably connected to the first opening 310, and the shell 500 is also arranged on the cavity wall of the refrigeration chamber 11. At least a part of the refrigeration pipe 400 is located inside the shell 500. Please refer to FIG. 6, the shell 500 also has a second opening 510 and a third opening 520. At least a part of the refrigeration pipe 400 extends out from the second opening 510 and enters the ice-making chamber shell 300 through the first opening 310. At least a part of the refrigeration pipe 400 also extends out from the third opening 520 and communicates with the reserved section 2100.

[0178] When the ice-making compartment housing 300 is detached, the ice-making compartment housing 300 is disengaged from the shell 500, and the refrigeration pipe 400 extending into the ice-making compartment housing 300 is extracted from the ice-making compartment housing 300, while the shell 500 remains connected to the cavity wall.

[0179] In other words, when the ice-making compartment housing 300 is detached, only the ice-making compartment housing 300 is disengaged from the shell 500, while the refrigeration pipe 400 and the shell 500 remain on the cavity wall.

[0180] In the refrigerator manufacturing process, the refrigeration cycle pipeline 200 is first assembled to the cabinet, and a portion of the refrigeration cycle pipeline 200 extends from the outer wall of the refrigeration cavity 11 into the interior of the refrigeration cavity 11 to form the reserved section 2100. The ice-making compartment housing 300 and the ice-making unit are also assembled into an integrated structure, and the refrigeration pipe 400 and the shell 500 are installed on the ice-making compartment housing 300. The ice-making compartment housing 300, the ice-making unit, the refrigeration pipe 400, and the shell 500 together form an integrated structure, which is then installed on the cavity wall of the refrigeration cavity 11 from the opening of the refrigeration cavity 11. Finally, the refrigeration pipe 400 extending from the third opening 520 is connected to the reserved section 2100, and the refrigeration pipe 400 is connected to the refrigeration cycle pipeline 200, so that the refrigeration pipe 400 and the refrigeration cycle pipeline 200 are in communication. Thus, the modular installation of the ice-making unit is achieved during the production and manufacturing process of the refrigerator.

[0181] When the ice-making unit needs to be maintained after sale, the connection between the shell 500 and the ice-making compartment housing 300 is disengaged, and the shell 500 and the ice-making compartment housing 300 are separated, and the shell 500 and the refrigeration pipe 400 remain on the cavity wall of the refrigeration cavity 11, as shown in FIG. 8. During the process of detaching the ice-making compartment housing 300, the refrigeration pipe 400 is gradually extracted from the interior of the ice-making compartment housing 300 until the ice-making compartment housing 300 is completely detached from the refrigeration cavity wall, at which time the ice-making compartment housing 300 and the ice-making unit remain an integrated structure.

[0182] After the ice-making unit is repaired, the ice-making compartment housing 300 and the ice-making unit can be installed back on the refrigeration cavity 11 as a whole. In some embodiments, the refrigeration pipe 400 is aligned with the first opening 310, so that the refrigeration pipe 400 is gradually inserted into the interior of the ice-making compartment housing 300, and after the ice-making compartment housing 300 and the shell 500 are connected, the ice-making compartment housing 300 and the ice-making unit can be quickly detached during the post-sale stage.

[0183] In the related art, the ice-making unit can only be installed modularly during the manufacturing process of the refrigerator. This is because the ice-making chamber housing 300 and the refrigeration pipe 400 are integrated in the related art, and after the ice-making chamber housing 300 is installed, the refrigeration pipe 400 is welded to the refrigeration cycle pipe 200, making it impossible to separate the refrigeration pipe 400 and the refrigeration cycle pipe 200. In this case, the ice-making unit can only be removed by removing each part of the ice-making unit and the ice-making chamber housing 300 one by one, and thus there is still a problem of complicated installation and removal in the post-sale stage.

[0184] In the refrigerator of the present embodiment, the housing 500 and the refrigeration pipe 400 passing through the housing 500 are provided, the housing 500 is detachably coupled to the ice-making chamber housing 300, and the housing 500 is further provided on the cavity wall of the refrigeration cavity 11. When the ice-making chamber housing 300 and the ice-making unit inside the ice-making chamber housing 300 are installed, the housing 500, the refrigeration pipe 400, and the ice-making chamber housing 300 are first installed as a whole, and then the whole is installed on the cavity wall. When the ice-making unit is maintained, the ice-making chamber housing 300 can be removed by only uncoupling the ice-making chamber housing 300 and the housing 500, and the refrigeration pipe 400 and the housing 500 are left on the cavity wall. Through such a structure, when the post-sale maintenance is performed, it is not necessary to remove each part one by one, the difficulty of disassembly is reduced, and the operation is simplified.

[0185] In some embodiments, an automatic docking and locking mechanism can be designed so that the housing 500 and the ice-making chamber housing 300 are automatically locked when installed through a spring or mechanical locking device, and are easily unlocked when disassembled through a simple button or manual rotation mechanism. Such a design can improve the convenience of disassembly and reduce the difficulty of operation for maintenance personnel. In some embodiments, pneumatic or electric driving devices can be introduced to start the automatic disassembly and installation process through a button or remote control when disassembled, which is particularly suitable for commercial refrigerators or scenarios that require frequent maintenance. This not only improves the efficiency of operation, but also reduces the dependence on operators. In addition to the existing matching structure of the housing 500 and the ice-making chamber housing 300, a more flexible modular connection method can be designed so that the ice-making unit, the refrigeration pipe, the housing, and the ice-making chamber housing 300 can be quickly connected and disassembled through standardized interfaces with other components. Such a design will make it more convenient for users or after-sales service personnel to replace parts. The interfaces between all modules are standardized, such as the refrigeration pipe interface, the water supply pipe interface, and the power interface, and the quick connection interface technology is used, so that each module can be disassembled and replaced through a unified standard, reducing the complexity of fault repair and maintenance.

[0186] In some embodiments, the shell 500 is clipped at the first opening 310, the shell 500 is clipped on the cavity wall; the force required to unclip the shell 500 from the ice-making compartment shell 300 is less than the force required to unclip the shell 500 from the cavity wall.

[0187] After the completion of the refrigerator manufacturing stage, the clip of the shell 500 and the cavity wall does not need to be unclipped in the post-maintenance stage, the shell 500 and the cavity wall remain in the state of being clipped, so that the shell 500 can always remain on the cavity wall of the refrigeration chamber 11. The clip between the shell 500 and the ice-making compartment shell 300 needs to be unclipped in the post-maintenance stage, so that the ice-making compartment shell 300 can be removed.

[0188] Because the shell 500 is clipped on the ice-making compartment shell 300 and the cavity wall respectively, in the post-maintenance stage, when the staff removes the ice-making compartment shell 300, the force required to unclip the shell 500 from the ice-making compartment shell 300 is less than the force required to unclip the shell 500 from the cavity wall, the clip of the ice-making compartment shell 300 and the shell 500 can be unclipped separately, without unclipping the clip between the shell 500 and the cavity wall of the refrigeration chamber 11.

[0189] The force required to unclip the shell 500 from the ice-making compartment shell 300 can be measured as follows: when the shell 500 and the ice-making compartment shell 300 are in the state of being clipped, fix the position of the shell 500, in the transverse direction, that is, the loading and unloading direction X, apply a force to the ice-making compartment shell 300 by a measuring tool such as a tensile meter, which forces the ice-making compartment shell 300 to move away from the shell 500, and read the reading of the tensile meter when the ice-making compartment shell 300 and the shell 500 are separated.

[0190] The force required to unclip the shell 500 from the cavity wall can be measured as follows: when the shell 500 and the cavity wall are in the state of being clipped, fix the position of the cavity wall, in the transverse direction, that is, the loading and unloading direction X, apply a force to the shell 500 by a measuring tool such as a tensile meter, which forces the shell 500 to move away from the cavity wall, and read the reading of the tensile meter when the cavity wall and the shell 500 are separated.

[0191] In some embodiments, in the current clamping structure, the force required to release the clamping of the shell 500 and the ice-making compartment shell 300 is less than the force required to release the clamping of the shell 500 and the cavity wall. In order to improve the flexibility of maintenance, a device that can adjust the clamping force can be designed. For example, using a locking mechanism with an adjusting screw, allowing users or maintenance personnel to adjust the clamping fastening force according to needs, so as to avoid the structure being unstable due to the clamping being too loose, or the disassembly being difficult due to the clamping being too tight. A spring-loaded clamping device can be introduced between the shell 500 and the ice-making compartment shell 300, and the clamping state is maintained by the pressure of the spring. This design can provide a certain auxiliary force when disassembling, so that the clamping is easier to release, while ensuring the stability of the fixation between the ice-making compartment shell 300 and the shell 500. Adding a clamping auxiliary structure such as a sliding groove, a slot or a gear-like structure on the contact surface of the shell 500 and the ice-making compartment shell 300 ensures that the clamping is more secure. Using this design can avoid wear due to use over time or frequent disassembly, making the clamping more stable and providing a smoother disassembly experience.

[0192] In some embodiments, referring to FIG. 3, in combination with FIG. 7, a boss 550 is provided on the shell 500, and a hook plate 320 is provided on the surface of the ice-making compartment shell 300, the hook plate 320 hooks the boss 550 to form the clamping of the boss 550 and the hook plate 320, and the surface section of the boss 550 clamped with the hook plate 320 is in the shape of a circular arc.

[0193] The cooperation of the boss 550 and the hook plate 320 can realize the clamping of the shell 500 and the ice-making compartment shell 300. In the clamped state, the hook plate 320 hooks the boss 550, and the boss 550 can limit the movement of the ice-making compartment shell 300 to the outside of the refrigeration cavity 11, maintaining the connection state of the ice-making compartment shell 300 and the shell 500. When the clamping is released, the worker needs to apply a larger force to the ice-making compartment shell 300 to make the hook plate 320 no longer hook on the boss 550.

[0194] Referring to FIG. 11, the surface of the boss 550 clamped with the hook plate 320 has a first unhooking part, which can reduce the contact area between the boss 550 and the hook plate 320, thereby reducing the friction therebetween, and thus reducing the force required to release the cooperation between the boss 550 and the hook plate 320, that is, the force required to release the clamping between the shell 500 and the ice-making compartment shell 300.

[0195] In some embodiments, the first unhooking part is designed as a circular arc-shaped cross section of the boss 550, or a slope is provided on the boss 550 to reduce the friction between the boss 550 and the hook plate 320.

[0196] The surface of the hook plate 320 that is engaged with the boss 550 has a second unhooking portion, which is also used to reduce the contact area between the boss 550 and the hook plate 320, thereby reducing the friction therebetween. On the basis that the cross section of the surface of the boss 550 that is engaged with the hook plate 320 is in the shape of a circular arc, the hook plate 320 is also provided in the shape of an arc, so that the contact between the hook plate 320 and the boss 550 is linear contact, thereby further reducing the force required to disengage the boss 550 and the hook plate 320.

[0197] In some embodiments, the second unhooking portion is provided in the shape of a circular arc on the surface of the hook plate 320, or a slope is provided on the surface of the hook plate 320, so as to reduce the friction between the boss 550 and the hook plate 320.

[0198] In some embodiments, referring to Figs. 9 and 10, the cavity wall is provided with a clearance portion 110 for avoiding the boss 550 and the hook plate 320.

[0199] The boss 550 is provided protruding from the surface of the shell 500, and the hook plate 320 is provided protruding from the surface of the ice-making compartment shell 300. When the ice-making compartment shell 300 is mounted on the cavity wall of the refrigeration compartment 11 via the shell 500, in order to prevent the cavity wall from interfering with the boss 550 and the hook plate 320, the clearance portion 110 is provided, thereby ensuring normal mounting of the ice-making compartment shell 300 and the shell 500.

[0200] In some embodiments, the shell 500 is further provided with a buckle head 560, and the cavity wall is provided with a buckling portion 120, the buckle head 560 being engaged in the buckling portion 120, and the contact surface between the buckle head 560 and the buckling portion 120 being a plane, which is referred to as a first plane 600.

[0201] By providing the buckle head 560 and the buckling portion 120, the connecting portion is engaged with the cavity wall of the refrigeration compartment 11, thereby facilitating mounting of the shell 500 on the cavity wall.

[0202] The buckle head 560 is provided on a plurality of sides of the shell 500, and the buckling portion 120 is also provided corresponding to the boss 550, thereby ensuring that the connecting portion can be stably stressed, so that it can be stably mounted on the cavity wall of the refrigeration compartment 11.

[0203] Because the contact surface between the buckle head 560 and the buckling portion 120 is a plane, the friction therebetween is relatively large, and after the buckle head 560 and the buckling portion 120 are engaged, they are not easily disengaged from each other.

[0204] Since the shell 500 and the ice-making chamber shell 300 are also clamped together, but through the form of the boss 550 and the hook plate 320, compared with the matching structure of the buckle head 560 and the buckle part 120, the structure of the boss 550 and the hook plate 320 is easier to disengage. In other words, in this embodiment, the engagement of the boss 550 and the hook plate 320 is equivalent to a live buckle, and the clamping of the two can be disengaged without damaging the boss 550 and the hook plate 320; while the buckle head 560 and the buckle part 120 are equivalent to a dead buckle, and if the clamping is to be disengaged, only the structure of the buckle head 560 or the buckle part 120 can be damaged, or both. In the after-sales maintenance stage, when the staff removes the ice-making chamber shell 300, the force required to separate the ice-making chamber shell 300 and the shell 500 is less than the force required to separate the shell 500 and the cavity wall, so that the refrigeration pipe and the shell 500 are left on the cavity wall. In some embodiments, the buckle part 120 is a buckle groove.

[0205] In some embodiments, on the basis of the first and second unhooking parts, a double unhooking mechanism can be introduced, that is, two layers of unhooking parts with different angles or shapes are arranged on the contact surface of the boss 550 and the hook plate 320, so that the clamping can be more easily disengaged under different forces. For example, the first unhooking part can be designed as a circular arc, and the second unhooking part can be designed as an inclined surface, so that the two unhooking structures can work together to make the disengagement of the clamping more smooth, especially when a smaller force is required to complete the disengagement. To further reduce the friction and reduce the difficulty of operation when disengaging the clamping, a sliding unhooking structure can be designed, which allows the hook plate 320 to gradually disengage from the boss 550 by sliding motion when disengaging the clamping. This design can reduce the need for direct pulling force, making the clamping part more stable and damage-free when disassembled. The contact surface of the boss 550 and the hook plate 320 can be surface coated, such as PTFE (polytetrafluoroethylene) coating or ceramic coating, to reduce the friction coefficient between the two. This will effectively reduce the force required to disengage the clamping and enhance the smoothness of the overall disassembly. At the contact site of the hook plate 320, a flexible material or a buffer layer is used, such as a soft rubber or silicone coating. This can reduce friction while also improving the impact resistance of the structure, preventing damage to the clamping part when disassembled due to excessive force.

[0206] Please refer to FIG. 12, the vertical plane where the disassembly direction X of the shell 500 relative to the cavity wall is located is recorded as the second plane 700, and the included angle a between the second plane 700 and the first plane 600 is not greater than 90°.

[0207] In some embodiments, the second plane 700 and the first plane 600 form an angle a of 90°, and the buckle head 560 is firmly clamped in the buckle 120, and it is not easy to release the clamping between them, so a greater force is needed to separate them from each other.

[0208] In some embodiments, the second plane 700 and the first plane 600 form an angle a of less than 90°, that is, a part of the buckle head 560 is embedded in the buckle 120, and it is more difficult to release the clamping between them, so a greater force is needed to separate them from each other.

[0209] In some embodiments, referring to FIGS. 5 and 6, the shell 500 includes a plug-in portion 530 and a connecting portion 540 which are in communication with each other, the plug-in portion 530 is arranged on the connecting portion 540, the refrigeration pipe 400 passes through the plug-in portion 530 and the connecting portion 540, the plug-in portion 530 is inserted into the inside of the ice-making compartment shell 300 from the first opening 310, the second opening 510 is arranged on the plug-in portion 530, and the connecting portion 540 is arranged on the cavity wall, and the third opening 520 is arranged on the connecting portion 540.

[0210] The arrangement of the plug-in portion 530 can fix the position of the refrigeration pipe 400, the plug-in portion 530 is inserted into the inside of the ice-making compartment shell 300 from the first opening 310, which can guide the movement path of the ice-making compartment shell 300 when it is disassembled, and on the other hand, it can facilitate the installation of the shell 500 on the ice-making compartment shell 300 during the refrigerator manufacturing stage.

[0211] In the direction in which the refrigeration pipe 400 extends outward from the second opening 510, the outer surface of the shell 500 is arranged as an inclined surface, so that the projection area of the shell 500 corresponding to the second opening 510 is the smallest area of the projection area of the shell 500, thereby facilitating the entry and exit of the shell 500 from the first opening 310.

[0212] The arrangement of the connecting portion 540 is used to connect the refrigeration cavity wall and the ice-making compartment shell 300.

[0213] In some embodiments, the shell 500 is internally provided with a heat preservation member, which wraps the refrigeration pipe 400 located inside the shell 500, that is, the refrigeration pipe 400 inside the plug-in portion 530 and the connecting portion 540.

[0214] The arrangement of the heat preservation member can reduce the heat exchange between the refrigeration pipe 400 inside the shell 500 and the outside, and reduce the influence of the path arrangement of the refrigeration pipe 400 on the ice-making compartment shell 300 cooling capacity.

[0215] In some embodiments, a receiving portion 130 is formed on the cavity wall for receiving the shell 500 and the refrigeration pipe 400.

[0216] Compared with the related structure of the ice-making chamber shell 300 in the related art, the shell 500 in the present embodiment is newly arranged on the outer surface of the ice-making chamber shell 300, which leads to the arrangement of the receiving portion 130 on the cavity wall to prevent interference with the installation of the ice-making chamber shell 300, the shell 500 and the refrigeration pipe 400.

[0217] In some embodiments, the receiving portion 130 is a receiving groove, and the connection between the shell 500 and the cavity wall is located on the groove wall of the receiving groove.

[0218] In some embodiments, the buckle portion 120 is arranged on the groove wall of the receiving groove, which can facilitate the arrangement of the connection portion 540 and the installation structure of the cavity wall, and prevent the depth of the receiving groove from being too deep to affect the arrangement of the foamed thermal insulation layer.

[0219] In some embodiments, the adjustable plug-in part, such as the plug-in part 530, can be designed with a locking ring or an adjustable locking mechanism, which can provide more flexibility during installation while ensuring the fixing accuracy of the refrigeration tube 400. A modular design can be adopted, allowing the plug-in part 530 to be separated from other parts of the shell 500, which facilitates manufacturing, installation, and later maintenance. The modular design helps to reduce assembly difficulty in the production process, improve manufacturing efficiency, and facilitate quick replacement of damaged parts during maintenance. The shape of the plug-in part 530 can be optimized to better guide the movement path of the ice-making compartment shell 300. In the design of the plug-in part, guide grooves or guide columns can be provided to ensure smooth movement of the ice-making compartment shell 300 along the predetermined path during disassembly, avoiding accidental interference or damage to other components. The connecting part 540 is used to connect the shell 500 and the cavity wall, and an adjustable connection mechanism can be considered, such as adjustable bolts, spring pins, or sliding grooves, to allow adjustment of the tightening force during production and maintenance. This design can enhance the stability of the structure while providing more flexibility for after-sales maintenance. The depth and shape of the accommodation groove can be further optimized to ensure sufficient accommodation space without affecting the arrangement of the insulation layer. Therefore, a depth-adjustable accommodation groove can be designed to adjust the depth of the groove during production according to specific needs, further improving the flexibility of the design. To avoid interference of the accommodation part 130 with the shell 500, refrigeration tube 400, or insulation layer, a guide ring or buffer pad can be added around the accommodation groove to effectively avoid interference or scratching of these components during installation. These buffer devices not only ensure smooth movement of the components during installation, but also effectively reduce vibration and friction during long-term use.

[0220] To further improve the assembly efficiency of the ice-making assembly and the convenience of after-sales maintenance, the following embodiments are optimized and extended based on the previous embodiments. In the previous embodiments, the disassembly design of the shell and the ice-making compartment shell facilitates maintenance, but there is still room for further optimization of the overall layout and air path of the ice-making assembly. The following embodiments improve the design of the ice-making assembly by integrating the outer frame, back plate, and ice maker, and optimize the cold air circulation path and air path circuit, which improves the ice-making efficiency and ensures a more compact and stable structure of the assembly. This optimization not only continues the design idea of simplifying disassembly and installation in the previous embodiments, but also improves the overall maintenance and assembly efficiency through more efficient cold air transmission and modular structure, thereby realizing a seamless transition from disassembly convenience to ice-making performance improvement.

[0221] Referring to FIG. 13, some embodiments of the present application provide a refrigerator, which includes a cabinet 1 and an ice-making assembly 29. The cabinet 1 is provided with a refrigeration compartment 121 and a freezing compartment 122. The ice-making assembly 29 is arranged in the refrigeration compartment 121 and uses the cold air of the freezing compartment 122 to make ice.

[0222] Referring to FIGS. 13 and 14, in some embodiments, the cabinet 1 is generally in the shape of a cuboid frame structure. The cabinet 1 includes a cabinet shell 13 and a cabinet body 12, the cabinet body 12 is arranged in the cabinet shell 13, and a mounting space is formed between the cabinet body 12 and the cabinet shell 13 for mounting other components and structures of the refrigerator and forming a foamed insulation layer. The inside of the cabinet body 12 forms a storage space for storing food. The cabinet shell 13 provides protection and support for the cabinet body 12.

[0223] Referring to FIGS. 13 and 14, in some embodiments, the inside of the cabinet body 12 forms a refrigeration chamber, which is divided into a refrigeration chamber 121 and a freezing chamber 122. The refrigeration chamber 121 is located at the upper part of the cabinet body 12, and the freezing chamber 122 is located at the lower part of the cabinet body 12. It should be noted that the positions of the refrigeration chamber 121 and the freezing chamber 122 can also be arranged in reverse order. One side of the refrigeration chamber 121 and one side of the freezing chamber 122 are both provided with a taking and placing opening for conveniently taking and placing articles. A door body is connected to the taking and placing opening, and the door body is connected to the cabinet 1 in a rotatable or sliding manner to open or close the taking and placing opening.

[0224] In some embodiments, the refrigerator further includes a refrigeration system (not shown in the figure) and a air supply system (not shown in the figure), which are electrically connected to the power supply assembly. The power supply assembly is used to supply power to the components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0225] The refrigeration system is installed in the cabinet 1, and is used to provide cold air to the refrigeration chamber inside the cabinet 12. The refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device, and a refrigerant. Each component is distributed at different positions of the cabinet 1 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are connected, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into high-temperature and high-pressure refrigerant gas by the compressor and then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the outside environment through the condenser, and the temperature drops. The high-temperature and high-pressure refrigerant gas is gradually cooled into a saturated vapor and then into a saturated liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered to remove water and impurities through the drying filter and then flows into the throttling device. The throttling device is used for throttling and pressure reduction, and the refrigerant becomes a wet vapor at a constant temperature and low pressure. The evaporation process is as follows: the wet vapor at a constant temperature and low pressure enters the evaporator, starts to absorb heat and vaporizes, reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and changes the refrigerant into a low-temperature and low-pressure gas. The refrigerant discharged from the evaporator returns to the compressor to repeat the above process. Through the state change of the refrigerant, energy conversion is realized, the heat in the refrigerator is transferred to the air outside the cabinet, and the refrigeration cycle of the refrigerator is realized.

[0226] The air supply system is installed in the cabinet 1 and is used to provide power for the cold air flow. The air supply system generally includes a fan and an air supply air duct defined in the cabinet 1. In some embodiments, the air supply air duct has an air inlet end close to the fan and an air outlet end away from the fan. In other embodiments, the air supply air duct has an air outlet end close to the fan and an air inlet end away from the fan. The cabinet 1 further defines an air duct cavity in communication with the air supply air duct and the refrigeration chamber inside the cabinet, so that the air supply air duct communicates with the refrigeration chamber through the air duct cavity. It should be noted that the cabinet 12 is provided with an air outlet for communicating the air duct cavity with the refrigeration chamber. The cold air generated by the refrigeration system is introduced into the air duct cavity through the air supply air duct by the operation of the fan, and then flows to the refrigeration chamber through the air outlet to refrigerate the refrigeration chamber. It should be noted that in some embodiments, the air outlet is arranged on the side wall of the cabinet 12 opposite to the opening of the refrigeration chamber or on the side wall adjacent to the opening of the refrigeration chamber. It should be noted that the refrigeration system and the air supply system belong to the related technology in the art, which will not be described here.

[0227] Referring to Fig. 16, in some embodiments, the ice making assembly 29 comprises an ice making box assembly 201 for making ice and an ice storage box assembly 22 for storing ice. Referring to Fig. 17, the ice making box assembly 201 comprises an outer frame 211, a back plate 2120 and an ice maker 2 arranged in the outer frame 211. Referring to Fig. 18, the ice storage box assembly 22 comprises a panel assembly 221 and an ice storage box 222 connected to the panel assembly 221. Referring to Fig. 19, the outer frame 211 has a first end 21101 and a second end 21102 arranged oppositely, and both the first end 21101 and the second end 21102 are open. The first end 21101 is arranged opposite to the inner wall of the refrigeration chamber 121, and the second end 21102 is connected to the panel assembly 221, so that the ice storage box 222 is arranged in the outer frame 211 and below the ice maker 2. Referring to Fig. 20, the back plate 2120 is arranged close to the first end 21101 and connected to the outer frame 211. The back plate 2120 is provided with an air supply port 21210 and an air return port 2122. The cold air of the freezing chamber 122 is supplied to the ice maker 2 through the air supply port 21210 for heat exchange, and the heat-exchanged cold air is returned to the freezing chamber 122 through the air return port 2122, forming a refrigeration cycle.

[0228] By arranging the panel assembly 221 and the ice storage box 222 integrally, and arranging the outer frame 211, the back plate 2120 and the ice maker 2 integrally, the ice making assembly 29 is modularized, which facilitates quick assembly and improves efficiency. When the ice maker 2 or the ice storage box 222 needs to be disassembled and repaired, the ice making box assembly 201 and the ice storage box assembly 22 are disassembled, and then the ice maker 2 or the ice storage box 222 is disassembled. When the ice maker 2 is disassembled, the overall structure of the ice storage box assembly 22 is not affected, and when the ice storage box 222 is disassembled, the overall structure of the ice making box assembly 201 is not affected, so that each component can be disassembled and repaired individually.

[0229] It should be noted that the first end 21101 and the second end 21102 of the outer frame 211 are open. The first end 21101 and the second end 21102 can be completely open, or only partially open, for example, only the middle part of the first end 21101 and the second end 21102 is open. The first end 21101 is arranged opposite to the inner wall of the refrigeration chamber 121, which can be connected or have a certain spacing.

[0230] In some embodiments, the back plate 2120 or the air outlet 21210 is designed as a porous structure, or uses a heat-conducting coating to improve heat exchange efficiency. The shape and layout of the air outlet 21210 and the air return 2122 are optimized to adopt air flow guide vanes or dynamic air duct design to improve cold air flow direction. The outer frame 211 can be designed with an adjustable internal space, and through adjustable partitions or deformable design, users can adjust the volume of the ice making box according to demand, so as to adapt to different ice quantity requirements, especially in scenarios with large demand changes to provide flexibility. The first end 21101 and the second end 21102 of the outer frame 211 are designed as sliding or snap-on openings, making installation or disassembly more convenient. At the same time, the openings can be designed in an adjustable form, such as using a detachable cover plate design, to facilitate cleaning and maintenance. The ice storage box 222 can be designed as a multi-layer partition structure, each partition can store different types of ice (such as crushed ice, block ice, etc.), or be designed as an adjustable space according to the cooling needs of the ice to increase the efficiency and flexibility of ice storage. The panel assembly 221 can be designed as transparent or translucent material, which is convenient for users to check the ice quantity in the ice storage box at any time. This design not only facilitates the inspection of the operator, but also avoids excessive opening of the ice storage box causing cold air loss.

[0231] Referring to FIGS. 19 and 20, in some embodiments, the outer frame 211 is a four-sided frame structure. The ice maker 2 is fixed to the top surface of the outer frame 211, and the ice storage box 222 is inserted into the outer frame 211 and located on the bottom surface of the outer frame 211, below the ice maker 2, to facilitate receiving and transporting the ice blocks made by the ice maker 2.

[0232] The outer frame 211 can be a whole frame or a split frame. Referring to FIG. 20, in some embodiments, the outer frame 211 is a split frame, and the outer frame 211 includes a first frame body 2111 and a second frame body 2112. The first frame body 2111 includes a first side wall 21111 and a second side wall 21112 connected to each other, and the first side wall 21111 and the second side wall 21112 are respectively arranged adjacent to the inner wall of the refrigeration compartment 121. The ice maker 2 is fixed to the first side wall 21111. The second frame body 2112 includes a third side wall 21121 and a fourth side wall 21122 connected to each other. The third side wall 21121 is arranged opposite to the first side wall 21111 and connected to the second side wall 21112. The fourth side wall 21122 is arranged opposite to the second side wall 21112 and connected to the first side wall 21111. The outer frame 211 is arranged as a split frame, which facilitates the assembly and disassembly of the outer frame 211. The first frame body 2111 and the second frame body 2112 are both L-shaped. After the first frame body 2111 and the second frame body 2112 are connected, the first side wall 21111, the second side wall 21112, the third side wall 21121 and the fourth side wall 21122 are butted to form a four-sided frame structure, and openings are reserved at both ends.

The thermal insulation layer is arranged between the inner layer 21131 and the outer layer 2113 of the first frame body 2111 and / or the second frame body 2112, and the thermal insulation layer is used to insulate the cold air and the hot air outside the outer frame 211. Since one of the first frame body 2111 and the second frame body 2112 needs to be attached to the box body 12 when the outer frame 211 is installed, the thermal insulation layer can be arranged only in the first frame body 2111 or the second frame body 2112. For example, when the ice-making box assembly 201 is installed at the upper left corner of the refrigeration chamber 121, the first frame body 2111 is attached to the box body 12, and the thermal insulation layer can be arranged only in the second frame body 2112; when the ice-making box assembly 201 is installed at the upper right corner of the refrigeration chamber 121, the second frame body 2112 is attached to the box body 12, and the thermal insulation layer can be arranged only in the first frame body 2111. In other embodiments, the thermal insulation layer can be arranged in the first frame body 2111 and the second frame body 2112. It should be noted that the structure and shape of the thermal insulation layer are the same as those of the first frame body 2111 or the second frame body 2112. For example, when the first frame body 2111 and the second frame body 2112 are both L-shaped, the thermal insulation layer is also L-shaped correspondingly.

Based on the air supply port 21210 and the return air port 2122 providing a channel for heat exchange, a guide plate or air guide groove can be added to ensure uniform airflow distribution, reduce dead angles of cold air flow, and improve cold air exchange efficiency, thereby improving ice making efficiency. The fixed frame 215 can be designed as a multi-point docking station with multiple locks or latches on the frame edge to ensure a tighter connection between the fixed frame 215 and the outer frame 211 and prevent loosening during long-term use. The frame part of the fixed frame 215 can be equipped with a sliding rail design to allow the ice storage box 222 to be inserted or removed more smoothly. The rail system can help the ice storage box 222 slide within the fixed frame 215, reducing the risk of misoperation and improving installation and removal efficiency.

[0243] It should be noted that in this application, the structure of the ice maker 2 in the ice box assembly 201 is a related technology. For example, the ice maker 2 is provided with an ice making box, an ice flipping assembly, etc.

[0244] Referring to FIG. 24, in some embodiments, the ice making box assembly 201 further comprises a motor mounting seat 214, which is arranged in the outer frame 211 and mounted on the back plate 2120, and the motor mounting seat 214 is provided with a hollow opening 2142, which is communicated with the air return opening 2122 to form an air return channel, and the air return pipe 21221 is communicated with the air return opening 2122. The cold air in the refrigeration chamber formed by the ice making assembly flows to the outside of the outer frame 211 through the hollow opening 2142, the air return channel, the air return opening 2122, and then flows back to the evaporator to form the air circuit of the refrigeration cycle during ice making. The motor mounting seat 214 is partially suspended to form the hollow opening 2142, which makes full use of the space in the depth direction of the ice making assembly 29, and avoids the motor mounting seat 214 from occupying too much area to affect the arrangement of the air circuit. The hollow opening 2142 can be provided with multiple hollow openings 2142, which are arranged at each side of the motor mounting seat 214, which not only increases the air return flow, but also ensures that each corner of the motor mounting seat 214 is connected with the back plate 2120, thereby ensuring the stability of the motor mounting seat 214 on the back plate 2120. The motor mounting seat 214 is used for mounting a crushed ice motor 2141, which is used for being connected with the ice storage box assembly 22, specifically being drivingly connected with the screw rod 2221 in the ice storage box assembly 22, to drive the screw rod 2221 to rotate, so as to transport the ice blocks in the ice storage box 222 to the ice outlet 22112 of the ice storage box assembly 22. The crushed ice motor 2141 is mounted on the partially suspended motor mounting seat 214, which reduces the occupied area of the crushed ice motor 2141 on the back plate 2120, and avoids the crushed ice motor 2141 from blocking the air flow. The motor mounting seat 214 and the back plate 2120 can be integrally formed, or can be fixed by welding or screws.

[0245] Referring to FIGS. 15 and 24, the air supply opening 21210 is arranged on the back plate 2120, and the air supply opening 21210 is arranged in the air supply opening 21210. The air supply opening 21210 is arranged opposite to the ice maker 2. The air supply opening 21210 is connected with the first air supply pipe 212120, which is connected with the ice making grid of the ice maker. The first air supply pipe 212120 is arranged in the ice making grid to ensure that the cold air supplied by the air supply opening 21210 is more accurately concentrated on the ice making grid, thereby ensuring the ice making efficiency. The first air supply pipe 212120 can be integrally arranged with the air supply opening 21210, or can be connected with the back plate screw or welded and fixed. The air supply opening 21210 is connected with the second air supply pipe 212110, which is connected with the freezing chamber 122. The air return pipe 21221 is connected with the air return opening 2122, and the air return pipe 21221 penetrates through the box body 12 and is connected with the freezing chamber 122. The second air supply pipe 212110 and the air return pipe 21221 are arranged in the mounting space formed between the box body 12 and the box shell 13.

[0246] Referring to FIG. 28, in some embodiments, the panel assembly 221 comprises an outer shell 2211, a filling layer 2212, and a cover plate 2213. The outer shell 2211 has a one-side opening receiving cavity 22111. The outer shell 2211 has an ice outlet 22112 in communication with the receiving cavity 22111. The filling layer 2212 is filled in the receiving cavity 22111, and has an avoiding gap 22121 opposite to the ice outlet 22112. The cover plate 2213 covers the receiving cavity 22111 and is connected with the outer shell 2211. The cover plate 2213 is connected with the ice storage box 222. The panel assembly 221 is composed of the outer shell 2211, the filling layer 2212, and the cover plate 2213, and is connected with the ice storage box 222. When the ice storage box 222 needs to be adapted to different models of refrigerator products, the panel assembly 221 can be universal, and only the corresponding ice storage box 222 needs to be replaced. The filling layer 2212 is a foam insulation layer, which can isolate external cold or hot air to avoid affecting the ice blocks in the ice storage box 222. The ice outlet 22112 is arranged at the bottom of the outer shell 2211. One side of the cover plate 2213 is connected with the outer shell 2211 by screws or buckles. The other side of the cover plate 2213 is connected with the fixing frame 215.

[0247] In some embodiments, the air supply port 21210 and the air return port 2122 can be designed as air supply ports and air return ports with adjustable air volume. For example, adjustable valves can be added to the pipes of the air supply ports and the air return ports to adjust the air volume according to different load requirements, optimize the cold air flow, and improve the ice making efficiency. The air supply pipe 212120 and the air return pipe 21221 can be provided with air flow guide plates or optimized air duct designs to make the cold air flow more precise, avoid waste of cold air or uneven distribution, and ensure that the cold air above the ice maker can be more concentrated on the ice making grid. At the air return pipe 21221 and the air supply pipe 212120, micro-channel heat exchangers or high-efficiency heat exchange materials (such as using metals or composite materials with high thermal conductivity) can be added to enhance the heat exchange efficiency of the refrigeration system, improve the refrigeration performance, and shorten the ice making time. The design of the motor mounting seat 214 connected to the back plate 2120 can increase the damping gasket or elastic fixed support to reduce the vibration generated by the motor during operation, reduce the stress on the back plate, and avoid unnecessary noise and vibration caused by long-term operation of the motor. The motor mounting seat material can use aluminum alloy or composite material instead of traditional metal material, which can reduce the weight of the motor mounting seat and improve its corrosion resistance and thermal conductivity, prolong its service life. In order to further improve the adaptability, more interchangeable modular panels can be designed, and users only need to replace different ice storage boxes 222 according to the refrigerator model and needs, without replacing the entire panel assembly. This not only improves the universality of the components, but also provides a convenient solution for later maintenance or upgrading. In order to improve the maintenance efficiency, the panel assembly 221 can be provided with sensors and intelligent modules such as temperature sensors, humidity sensors, and air speed sensors to monitor the working state of the ice maker in real time. If the system detects an abnormality (such as ice blockage, motor overheating, etc.), the user can be notified through a smart terminal (such as a mobile phone App) to provide fault diagnosis and solutions, reducing the frequency of manual inspection.

[0248] It should be noted that in this application, the ice storage box assembly 22, the ice storage, the ice crushing, and the ice outlet related structure and principle are related technologies. For example, the ice storage box 222 is a box structure with one side open, which receives the ice blocks dropped by the ice maker 2. The screw rod 2221 is arranged in the ice storage box 222, and the ice blocks are transported to the ice outlet of the ice storage box 222 through the transmission of the screw rod 2221; one end of the screw rod 2221 is also connected to the ice crushing assembly 2222, the ice crushing assembly 2222 penetrates through the cover plate 2213 and is arranged in the avoiding gap 22121 of the filling layer 2212, and the ice crushing motor 2141 drives the ice crushing assembly 2222 to crush the ice blocks and drop them to the ice outlet of the ice storage box 222; a baffle is arranged at the ice crushing assembly 2222, and the baffle can be opened and closed to block the ice crushing or make the ice crushing drop out. In this application, the ice storage box assembly 22 also includes a motor for driving the baffle to open and close, which facilitates the ice crushing to drop to the ice outlet 22112 of the shell 2211.

[0249] The application also provides a refrigerator, which comprises a cabinet 1 and an ice making assembly 29, the cabinet 1 comprises a cabinet shell 13 and a cabinet liner 12, the inside of the cabinet liner 12 forms a refrigeration chamber, the refrigeration chamber is divided into a refrigeration compartment 121 and a freezing compartment 122; the ice making assembly 29 is arranged in the refrigeration compartment 121 and uses the cold air of the freezing compartment 122 to make ice. The ice making assembly 29 comprises an ice making box assembly 201 and an ice storage box assembly 22, the ice making box assembly 201 is used for making ice, and the ice storage box assembly 22 is used for storing ice. The ice making box assembly 201 comprises an outer frame 211, a back plate 2120 and an ice maker 2 arranged in the outer frame 211, and the ice storage box assembly 22 comprises a panel assembly 221 and an ice storage box 222 connected to the panel assembly 221. The outer frame 211 has a first end 21101 and a second end 21102, and the first end 21101 and the second end 21102 are both arranged in an open manner; the side facing the refrigeration compartment 121 when the refrigeration compartment 121 is used is the front side (i.e. the side of the refrigeration compartment 121 provided with a taking and placing opening), the second end 21102 and the first end 21101 are arranged opposite to each other along the front-rear direction of the refrigeration compartment 121, the first end 21101 is opposite to the inner wall of the refrigeration compartment 121, the panel assembly 221 is connected to the second end 21102, so that the ice storage box 222 is inserted into the outer frame from the front side of the refrigeration compartment 121 and is arranged below the ice maker 2; the back plate 2120 is arranged close to the first end 21101 and is connected to the outer frame 211, the back plate 2120 is provided with an air supply port 21210 and an air return port 2122, the air supply port 21210 is connected with a first air supply pipe 212120, the cold air of the freezing compartment 122 is sent into the ice maker 2 through the air supply port 21210 and the first air supply pipe 212120 to exchange heat, and the heat-exchanged cold air is returned to the freezing compartment 122 through the air return port 2122 to form a refrigeration cycle.

[0250] The panel assembly 221 and the ice storage box 222 are integrally arranged, and the outer frame 211, the back plate 2120 and the ice maker 2 are integrally arranged, so that the ice making assembly 29 is modularized, the ice making assembly 29 is conveniently and quickly assembled, and the efficiency is improved.

[0251] In the foregoing embodiments, the ice making assembly realizes heat exchange processes based on the refrigeration chamber and the freezing chamber to produce ice cubes through the cooperation of the ice making box assembly and the ice storage box assembly, and effectively utilizes the cold air of the freezing chamber for refrigeration circulation. This design not only improves the assembly efficiency of the ice making assembly, but also facilitates disassembly and maintenance. However, with the completion of the ice making process, the delivery and distribution of ice cubes also require an efficient and reliable transmission system. To further simplify the delivery and operation of crushed ice and whole ice, the following embodiments further improve the operation performance and flexibility of the ice maker by introducing a more precise mechanical transmission system. In the following embodiments, the structure of the ice maker includes an ice storage box, a driving member, an ice knife shaft, and a conveying screw, and the transmission system controls the relative rotation direction of the conveying screw and the ice knife shaft through different working states of the first transmission assembly and the second transmission assembly, thereby simplifying the selection mechanism of the ice outlet, avoiding the complex ice outlet selector in traditional designs, and realizing more efficient ice output.

[0252] Referring to FIG. 29, the refrigerator according to an embodiment of the present application includes a cabinet 1 and an ice maker 2. The ice maker 2 is disposed in the cabinet 1 to prepare ice cubes.

[0253] Referring to FIG. 29, in some embodiments, the cabinet 1 has a substantially rectangular frame structure. The cabinet 1 includes a cabinet shell (not shown in the drawings) and a cabinet liner. The cabinet liner is disposed in the cabinet shell, and a mounting space is formed between the cabinet liner and the cabinet shell for mounting other components of the refrigerator and forming a foamed thermal insulation layer. The inside of the cabinet liner forms a storage space for storing food. The cabinet shell provides protection and support for the cabinet liner.

[0254] Referring to FIG. 29, in some embodiments, the inside of the cabinet liner forms a refrigeration chamber 11, which can have a refrigeration function or a freezing function. The refrigeration chamber 11 is generally divided into a refrigeration chamber and a freezing chamber. The refrigeration chamber is located at the upper part of the cabinet liner, and the freezing chamber is located at the lower part of the cabinet liner. It should be noted that the positions of the refrigeration chamber and the freezing chamber can also be reversed, and the refrigeration chamber 11 can also be provided with only a refrigeration chamber or only a freezing chamber. One side of the refrigeration chamber and one side of the freezing chamber are both provided with a taking and placing opening for conveniently taking and placing articles. A door body is connected to the taking and placing opening, and the door body is connected to the cabinet 1 in a rotatable or sliding manner to open or close the taking and placing opening.

[0255] In some embodiments, the refrigerator further includes a refrigeration system (not shown) and an air supply system (not shown). The refrigeration system and the air supply system are electrically connected to a power supply assembly. The power supply assembly supplies power to the components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0256] The refrigeration system is installed in the cabinet 1, and is used to provide cold air to the refrigeration chamber 11 inside the cabinet. The refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device, and a refrigerant. Each component is distributed at different positions of the cabinet 1 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are connected, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into high-temperature and high-pressure refrigerant gas by the compressor and then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the outside environment through the condenser, and the temperature drops. The high-temperature and high-pressure refrigerant gas is gradually cooled into a saturated vapor and then into a saturated liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered to remove water and impurities through the drying filter and then flows into the throttling device. The throttling device is used for throttling and pressure reduction, and the refrigerant becomes a wet vapor at a constant temperature and low pressure. The evaporation process is as follows: the wet vapor at a constant temperature and low pressure enters the evaporator, starts to absorb heat and vaporizes, reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and changes the refrigerant into a low-temperature and low-pressure gas. The refrigerant discharged from the evaporator returns to the compressor to repeat the above process. Through the state change of the refrigerant, energy conversion is realized, the heat in the refrigerator is transferred to the air outside the cabinet, and the refrigeration cycle of the refrigerator is realized.

[0257] The air supply system is installed in the cabinet 1 and is used to provide power for the cold air flow. The air supply system generally includes a fan and an air supply air duct defined in the cabinet 1. In some embodiments, the air supply air duct has an air inlet end close to the fan and an air outlet end away from the fan. In other embodiments, the air supply air duct has an air outlet end close to the fan and an air inlet end away from the fan. The cabinet 1 further defines an air duct cavity in communication with the air supply air duct and the refrigeration chamber 11 inside the cabinet, so that the air supply air duct communicates with the refrigeration chamber 11 through the air duct cavity. It should be noted that the cabinet is provided with an air outlet for communicating the air duct cavity with the refrigeration chamber 11. The cold air generated by the refrigeration system is introduced into the air duct cavity through the air supply air duct by the operation of the fan, and then flows to the refrigeration chamber 11 through the air outlet to refrigerate the refrigeration chamber 11. It should be noted that in some embodiments, the air outlet is arranged on the side wall opposite to the opening of the refrigeration chamber 11 or on the side wall adjacent to the opening of the refrigeration chamber 11. It should be noted that the refrigeration system and the air supply system belong to the related technology in the art, which will not be described here.

[0258] Referring to Fig. 30, in combination with Figs. 31 and 32, the ice maker 2 comprises an ice storage box 21, a driving member 20, an ice knife shaft 23 and a conveying screw 24, the ice storage box 21 is provided with an ice outlet 281; the driving member 20 has a power output shaft; the ice knife shaft 23 is rotatably assembled in the ice storage box 21, one end of the ice knife shaft 23 is provided with a broken ice knife 231, the other end of the ice knife shaft 23 extends out of the ice storage box 21 and is connected with the power output shaft; the conveying screw 24 is arranged in the ice storage box 21, two ends of the conveying screw 24 are respectively fixed with a first transmission assembly 25 and a second transmission assembly 26, the first transmission assembly 25 and the second transmission assembly 26 are respectively connected with the ice knife shaft 23, the first transmission assembly 25 and the second transmission assembly 26 both have a first state of synchronously rotating the conveying screw 24 with the ice knife shaft 23 and a second state of relatively rotating the conveying screw 24 with the ice knife shaft 23; when the driving member 20 drives the ice knife shaft 23 to rotate, the first transmission assembly 25 or the second transmission assembly 26 drives the conveying screw 24 to rotate, and the rotating direction of the conveying screw 24 is the same as or opposite to the rotating direction of the ice knife shaft 23.

[0259] When the driving member 20 drives the ice knife shaft 23 to rotate in a set direction, the broken ice knife 231 at the end of the ice knife shaft 23 performs broken ice operation, the first transmission assembly 25 or the second transmission assembly 26 drives the conveying screw 24 to rotate in the same direction as the ice knife shaft 23, at this time, the conveying screw 24 conveys ice blocks to the ice outlet 281 of the ice storage box 21, and the broken ice is output through the ice outlet 281. When the driving member 20 drives the ice knife shaft 23 to rotate reversely, the broken ice knife 231 at the end of the ice knife shaft 23 no longer performs broken ice operation, the first transmission assembly 25 or the second transmission assembly 26 drives the conveying screw 24 to rotate in the opposite direction to the ice knife shaft 23, at this time, the conveying screw 24 still conveys ice blocks to the ice outlet 281 of the ice storage box 21, and the whole ice blocks are output through the ice outlet 281.

[0260] In some embodiments of the present application, the driving member 20 can drive the ice skate shaft 23 to move in two directions, and the rotation direction of the ice skate shaft 23 determines whether the ice crushing blade 231 performs the ice crushing operation. When the ice skate shaft 23 rotates, the first transmission assembly 25 or the second transmission assembly 26 drives the conveying screw 24 to rotate in the same direction or opposite direction as the ice skate shaft 23, so that the rotation direction of the conveying screw 24 is fixed, and the conveying screw 24 always rotates in the direction of conveying ice blocks to the ice outlet 281 of the ice storage box 21, so that the ice crushing operation of the ice crushing blade 231 does not affect the conveying of ice blocks. According to the arrangement of the present application, the complicated ice outlet selector at the ice outlet 281 of the ice maker 2 can be cancelled, and the overall structure of the ice maker 2 is simplified. Moreover, the ice skate shaft 23 and the conveying screw 24 are two independent components, the driving member 20 directly drives the ice skate shaft 23 to rotate, and determines whether the ice crushing blade 231 performs the ice crushing operation. When the ice crushing blade 231 does not perform the ice crushing operation, the rotation direction of the conveying screw 24 is unchanged, and the conveying screw 24 still conveys ice blocks to the ice outlet 281, avoiding the generation of crushed ice while the ice outlet 281 outputs whole ice blocks.

[0261] In some embodiments of the present application, the driving member 20 can drive the ice skate shaft 23 to rotate forward and reverse, and no matter whether the ice skate shaft 23 rotates forward or reverses, the ice skate shaft 23 can drive the conveying screw 24 to rotate in a fixed direction through the first transmission assembly 25 or the second transmission assembly 26. Since the function of the conveying screw 24 is to convey ice blocks to the ice outlet 281 of the ice storage box 21, the rotation direction of the conveying screw 24 needs to meet the demand of conveying ice blocks to the ice outlet 281. Therefore, the rotation direction of the conveying screw 24 conveying ice blocks to the ice outlet 281 is the first set direction (the direction indicated by the arrow in FIG. 33 and FIG. 35 is the first set direction, that is, the counterclockwise direction shown in the figure), and the first transmission assembly 25 and the second transmission assembly 26 are configured to enable the conveying screw 24 to rotate synchronously with the ice skate shaft 23 in the first set direction and enable the conveying screw 24 to rotate relative to the ice skate shaft 23; the driving member 20 can drive the ice skate shaft 23 to rotate in two directions, and the ice skate shaft 23 can drive the conveying screw 24 to rotate in the first set direction through the first transmission assembly 25 or the second transmission assembly 26, which can be another embodiment of the present application. When the ice skate shaft 23 rotates in the first set direction, the conveying screw rotates in the same direction as the ice skate shaft 23, and when the ice skate shaft 23 reverses, the conveying screw rotates in the opposite direction of the ice skate shaft 23.

[0262] It should be noted that the ice maker 2 can be arranged in a refrigeration chamber. The ice maker 2 further comprises an ice making box 27, an ice flipping assembly and other related components for ice making, which will not be described in detail herein.

[0263] In some embodiments, the driving member 20, the first and second transmission assemblies 25, 26 are designed as a centralized driving module, which drives the ice cutter shaft and the conveying screw through a single motor, reducing the mechanical complexity. An automatic opening and closing mechanism is added to the ice outlet 281, which automatically opens when the user needs ice, and automatically closes after the ice output is completed, avoiding the ice being exposed to the external environment for a long time, keeping the ice clean and sanitary. Higher efficiency motors are used in the driving system to reduce energy consumption. Energy-saving technologies such as direct-current brushless motors or variable frequency control systems are used to control the speed of the ice cutter shaft 23 and the conveying screw 24, control the power output, and ensure the efficiency of the ice making process. By optimizing the design of the ice storage box 21, its capacity is larger to accommodate more ice. A stacked or compartmented design can be used to increase the storage density of the ice and facilitate the automatic layered output of the ice. The sharpness of the ice cutter 231 is increased or the shape of the ice cutter is adjusted to enable more efficient and faster cutting of ice, reducing the time of the ice cutter operation, thereby increasing the ice making speed.

[0264] Referring to FIGS. 31 and 32, the ice storage box 21 is provided in the ice maker 2 to perform ice storage, ice crushing, and ice output functions. The ice storage box 21 is a box structure with one side open and is located below the ice making box 27 to receive the formed ice. The ice storage box 21 is also provided with a panel 28 on one side, and the ice outlet 281 is provided on the panel 28. The panel 28 is provided with an ice cutter shell 282, and one end of the ice cutter shaft 23 extends into the ice cutter shell 282 through the ice storage box 21, so that the ice cutter 231 at the end of the ice cutter shaft 23 is located in the ice cutter shell 282 and opposite the ice outlet 281. It should be noted that the end of the ice cutter shaft 23 can be provided with multiple ice cutters 231 spaced along the axial direction. The ice outlet 281 is also provided with a baffle to open or close the ice outlet 281. The driving member 20 is a motor provided outside the ice storage box 21 and opposite the panel 28. The ice cutter shaft 23 extends outside the ice storage box 21 and is connected to the power output shaft of the motor to drive the ice cutter shaft 23 to rotate forward and backward. The conveying screw 24 is provided in the ice storage box 21, and the conveying screw 24 spirally surrounds the outer periphery of the ice cutter shaft 23. When the conveying screw 24 rotates in the first set direction, it can convey ice to the ice outlet 281, and when the conveying screw 24 rotates in the opposite direction, it cannot perform the ice conveying function.

[0265] Referring to FIG. 32, in combination with FIGS. 36 and 39, in some embodiments, the first transmission assembly 25 includes a first rotating member 251 and a first connecting structure 252. The first rotating member 251 is sleeved on the blade shaft 23 and fixed with the conveying screw 24, so that the conveying screw 24 can rotate synchronously with the first rotating member 251. The first connecting structure 252 is connected between the first rotating member 251 and the blade shaft 23. In a first state, the first connecting structure 252 is configured to relatively fix the first rotating member 251 and the blade shaft 23. In a second state, the first connecting structure 252 is configured to relatively rotate the first rotating member 251 and the blade shaft 23. The relative state between the first rotating member 251 and the blade shaft 23 is adjusted by the first connecting structure 252, so that the first rotating member 251 and the blade shaft 23 are relatively fixed or relatively rotated. In the first state, the first rotating member 251 and the blade shaft 23 are relatively fixed, so that the first rotating member 251 can rotate synchronously with the blade shaft 23. Since the first rotating member 251 is fixed with the conveying screw 24, when the first rotating member 251 rotates, the conveying screw 24 rotates synchronously, so that the conveying screw 24 rotates synchronously with the blade shaft 23, and the rotating direction of the conveying screw 24 is the same as that of the blade shaft 23. In the second state, the first rotating member 251 and the blade shaft 23 are relatively rotated, so that when the blade shaft 23 rotates, the rotating direction of the first rotating member 251 is opposite to that of the blade shaft 23, and the rotating direction of the conveying screw 24 is opposite to that of the blade shaft 23. Therefore, when the blade shaft 23 rotates in a first set direction, the first connecting structure 252 can drive the conveying screw 24 to rotate synchronously with the blade shaft 23 in the first set direction.

[0266] Referring to FIGS. 38, 39 and 41, in some embodiments, the first connecting structure 252 includes a first stop member 2521, a first guide portion 2522 and a first stop portion 2523. The first stop member 2521 is inserted into the first rotating member 251 and can elastically extend at least partially toward the axial center of the blade shaft 23. The first guide portion 2522 is fixed on the blade shaft 23 and has a first guide surface 25221. In the second state, the first guide surface 25221 applies a pushing force toward the inside of the first rotating member 251 to the end surface of the extending portion of the first stop member 2521. The first stop portion 2523 is fixed on the blade shaft 23 and connected with the first guide portion 2522. The first stop portion 2523 has a first stop surface 25231. In the first state, the first stop surface 25231 abuts against the side surface of the extending portion of the first stop member 2521.

[0267] In the first state, when the ice skate shaft 23 rotates in the first set direction, which is counterclockwise in this embodiment, the first stop surface 25231 abuts against the side surface of the protruding part of the first stop piece 2521, so that the first stop part 2523 drives the first stop piece 2521 to rotate in the first set direction synchronously. Since the first stop piece 2521 is fixed with the first rotating piece 251, when the first stop piece 2521 rotates in the first set direction along with the first stop part 2523, the first rotating piece 251 rotates in the first set direction synchronously. Since the conveying screw 24 is fixedly connected with the first rotating piece 251, the conveying screw 24 rotates in the first set direction synchronously along with the ice skate shaft 23 under the driving of the ice skate shaft 23 through the transmission of the first stop part 2523, the first stop piece 2521 and the first rotating piece 251, so as to ensure the conveying function of the conveying screw 24. In addition, when the ice skate shaft 23 rotates in the first set direction, the ice chipper 231 at the end of the ice skate shaft 23 rotates in the first set direction synchronously, so that the ice chipper 231 performs the ice chipping operation, thereby chipping ice while the conveying screw 24 is conveying ice blocks to the ice outlet 281, so that the ice chips are discharged from the ice outlet 281, and the ice maker discharges ice chips.

[0268] In the second state, when the ice skate shaft 23 rotates reversely, which is clockwise in this embodiment, the first guide surface 25221 applies a pushing force to the end surface of the protruding part of the first stop piece 2521 towards the inside of the first rotating piece 251, so that the first stop piece 2521 elastically deforms and partially retracts into the first rotating piece 251. The first stop piece 2521 and the first stop part 2523 do not stop each other, so that the ice skate shaft 23 can rotate relative to the first rotating piece 251, thereby the ice skate shaft 23 can rotate relative to the conveying screw 24. At this time, the ice skate shaft 23 provides a driving force for the conveying screw 24 to rotate in the first set direction through the second transmission assembly 26, and the first transmission assembly 25 plays a role of following transmission. In addition, when the ice skate shaft 23 rotates reversely, the ice chipper 231 at the end of the ice skate shaft 23 rotates reversely synchronously, so that the ice chipper 231 does not perform the ice chipping operation, and the ice blocks conveyed by the conveying screw 24 are directly output through the ice outlet 281, thereby the ice maker discharges whole ice blocks.

[0269] In some embodiments, the first guide portion 2522 and the first stop portion 2523 are integrally formed with the blade shaft 23 for easy manufacturing. The outer periphery of the first rotating member 251 is sleeved with a first fixed sleeve 2511, and the first stop member 2521 is fixed to the inner wall of the first fixed sleeve 2511 and can extend into the space between the first rotating member 251 and the blade shaft 23. The first fixed sleeve 2511 serves as a bearing for the first stop member 2521. The end of the first stop member 2521 can also be directly fixed to the first rotating member 251. In other embodiments, the first guide portion 2522 and the first stop portion 2523 can also be two separate components that are fixed to the blade shaft 23 by welding.

[0270] In some embodiments, to improve the flexibility of the ice maker, the design of the first rotating member 251 can be further optimized to ensure that it can accurately control the bidirectional rotation of the blade shaft 23 and the conveying screw 24. For example, an electric or electromagnetic adjusting component can be added to achieve a smoother switching state through an electric control system, so that the friction and vibration between parts are minimized during the switching state, thereby improving the operation stability and prolonging the service life. More wear-resistant materials (such as high-strength alloys or ceramic coatings) can be considered for use in key components such as the first rotating member 251, the first connecting structure 252, and the first stop member 2521 to reduce wear during long-term use and avoid mechanical failures caused by long-term use. An automatic cleaning mechanism can be designed for the conveying screw 24 and the blade shaft 23 to automatically remove ice accumulation or impurities in the ice storage box by periodically changing the rotation direction of the conveying screw or starting a cleaning mode (such as high-pressure water flow or air flow), thereby reducing failures caused by blockage. A simple and intuitive operation panel can be designed for the ice maker, allowing users to easily set the ice making mode, adjust the ice output, or monitor the ice making status. In addition, an LED display screen can be added to display the ice generation progress, the current mode, and fault alarm information.

[0271] Referring to FIGS. 39 and 41, in some embodiments, the blade shaft 23 is provided with a first notch 232, one side wall of the first notch 232 forms a first guide surface 25221, and the other side wall of the first notch 232 forms a first stop surface 25231. The length direction of the first notch 232 extends along the axial direction of the blade shaft 23, the first guide surface 25221 is an arc-shaped surface protruding towards the first rotating member 251, and the first guide surface 25221 is smoothly connected with the wall surface of the blade shaft 23. The first guide surface 25221 is connected with the first stop surface 25231.

[0272] The first stop surface 25231 and the first guide surface 25221 are arranged in sequence in the first set direction, and the first stop surface 25231 abuts against the side surface of the protruding portion of the first stop piece 2521 when the blade shaft 23 rotates in the first set direction, i.e., counterclockwise in the embodiment, so that the first stop surface 25231 pushes the first stop piece 2521, and the first rotating piece 251 rotates synchronously with the blade shaft 23.

[0273] When the blade shaft 23 rotates reversely, i.e., clockwise in the embodiment, the first rotating piece 251 does not be driven, and rotates relatively with the blade shaft 23. Specifically, the first rotating piece 251 is coaxially sleeved on the outer circumferential side of the blade shaft 23, the first gap 232 is located between the blade shaft 23 and the first rotating piece 251, and the first stop piece 2521 partially protrudes into the first gap 232 and abuts against the first stop surface 25231. When the blade shaft 23 rotates reversely, the first guide surface 25221 pushes the end surface of the protruding portion of the first stop piece 2521, and when the blade shaft 23 rotates to the position where the first guide surface 25221 is separated from the first stop piece 2521, the first stop piece 2521 is pushed by the wall surface of the blade shaft 23 until the wall surface of the blade shaft 23 is separated from the first stop piece 2521. At this time, the elastic reset portion of the first stop piece 2521 protrudes into the first gap 232, and the first stop piece 2521 is pushed again by the first guide surface 25221 with the continuous rotation of the blade shaft 23, so as to avoid the interference of the first stop piece 2521 with the relative rotation of the first rotating piece 251 and the blade shaft 23.

[0274] In some embodiments, the first rotating piece 251 is a bearing, and the first stop piece 2521 is a floating pin which can retract under the pushing force and automatically reset to protrude when the pushing force is lost. In other embodiments, the first stop piece 2521 can be a baffle structure which is partially inserted into the first rotating piece 251 and connected to the first rotating piece 251 by an elastic member.

[0275] Referring to FIG. 37, in some embodiments, the second transmission assembly 26 includes a second rotating member 261, a third rotating member 262, and a second connecting structure 263. The second rotating member 261 is rotatably sleeved on the ice skate shaft 23 and fixed with the conveying screw 24, so that the conveying screw 24 can rotate synchronously with the second rotating member 261. The second rotating member 261 rotates relative to the ice skate shaft 23. The third rotating member 262 is rotatably sleeved on the ice skate shaft 23 and configured to rotate in the opposite direction of the ice skate shaft 23. The second rotating member 261 is at least partially coaxially inserted into the third rotating member 262. The second connecting structure 263 is connected between the second rotating member 261 and the third rotating member 262. In the first state, the second connecting structure 263 is configured to allow the second rotating member 261 to rotate relative to the third rotating member 262. In the second state, the second connecting structure 263 is configured to fix the second rotating member 261 relative to the third rotating member 262.

[0276] In the first state, the ice skate shaft 23 rotates in the first set direction, which is counterclockwise in this embodiment. The ice skate shaft 23 drives the third rotating member 262 to rotate in the opposite direction. In the first state, the second rotating member 261 rotates relative to the third rotating member 262, so that the rotating directions of the second rotating member 261 and the third rotating member 262 are opposite. The third rotating member 262 does not drive the second rotating member 261. At this time, the ice skate shaft 23 drives the conveying screw 24 to rotate synchronously in the first set direction through the first transmission assembly 25. The conveying screw 24 drives the second rotating member 261 to rotate in the first set direction. When the conveying screw 24 rotates in the first set direction, it performs the function of conveying ice blocks to the ice outlet 281. At this time, the ice chipper 231 at the end of the ice skate shaft 23 rotates in the first set direction to perform the ice chipping operation, so that ice chipping is performed while ice blocks are conveyed, realizing the function of the ice maker to output ice chips.

[0277] In the second state, the ice skate shaft 23 rotates reversely, clockwise in the embodiment, and drives the third rotating member 262 to rotate in the first set direction. In the second state, the second rotating member 261 is fixed relative to the third rotating member 262 through the second connecting structure 263, and the third rotating member 262 drives the second rotating member 261 to rotate in the first set direction synchronously. In the second state, the ice skate shaft 23 does not drive the first rotating member 251, and the first rotating member 251 follows the movement of the conveying screw 24. At this time, the conveying screw 24 still rotates in the first set direction to perform the function of conveying ice blocks, and the ice crusher 231 rotates reversely with the ice skate shaft 23 to perform the function of not crushing ice. The movement of the conveying screw 24 is separated from the movement of the ice crusher 231, so that the conveying screw 24 conveys whole ice blocks to the ice outlet 281, realizes the function of the ice maker to output whole ice blocks, and avoids the occurrence of crushed ice.

[0278] In some embodiments, an anti-stuck mechanism can be designed at the matching part of the ice skate shaft 23 and the conveying screw 24. For example, an anti-skid or friction-reducing coating is added to the outer ring of the conveying screw to avoid the stuck phenomenon caused by excessive accumulation of ice blocks. In addition, a sensor can be used to detect abnormalities in the conveying process, such as ice block blockage, and start the reverse function or automatic cleaning mode in time to avoid faults. Redundant transmission design is introduced to ensure that when the main transmission system fails, the standby system can take over in time. For example, a standby automatic separation mechanism is set to automatically switch to the standby system when the main system fails, ensuring the continuous operation of the ice maker.

[0279] Referring to FIGS. 40 and 42, in some embodiments, the second connecting structure 263 includes a second stop piece 2631, a second guide part 2632, and a second stop part 2633. The second stop piece 2631 is inserted into the third rotating member 262 and can at least partially elastically extend toward the second rotating member 261. The second guide part 2632 is fixed to the second rotating member 261 and has a second guide surface 26321 that applies a pushing force toward the inside of the third rotating member 262 to the end surface of the extending part of the second stop piece 2631 in the first state. The second stop part 2633 is fixed to the second rotating member 261 and connected with the second guide part 2632. The second stop part 2633 has a second stop surface 26331 that abuts against the side surface of the extending part of the second stop piece 2631 in the second state.

[0280] In the first state, a pushing force is applied to the end surface of the protruding portion of the second stopper 2631 through the second guide surface 26321, so that the second stopper 2631 is elastically deformed and partially retracts into the third rotating member 262, so that the second rotating member 261 and the third rotating member 262 can relatively rotate; since the rotating direction of the third rotating member 262 is opposite to that of the blade shaft 23, when the second rotating member 261 and the third rotating member 262 relatively rotate, the rotating direction of the second rotating member 261 is the same as that of the blade shaft 23, at this time, the blade shaft 23 drives the conveying screw 24 to rotate through the first transmission assembly 25, and the second rotating member 261 follows the movement of the conveying screw 24. In the second state, the second stopper surface 26331 abuts against the protruding portion of the second stopper 2631, so that the second rotating member 261 and the third rotating member 262 are relatively fixed, the second rotating member 261 can synchronously rotate with the third rotating member 262, so that the second rotating member 261 rotates under the driving action of the third rotating member 262, the second rotating member 261 drives the conveying screw 24 to rotate, at this time, the first rotating member 251 follows the movement of the conveying screw 24. The second stopper 2631 is a floating pin, and the protruding portion can automatically reset.

[0281] In some embodiments, referring to FIGS. 33 and 34, the second guide portion 2632 and the second stop portion 2633 are integrally formed with the second rotating member 261, as shown in FIG. 40. The outer periphery of the third rotating member 262 can be fixedly sleeved with a second fixed sleeve 2621, the second stopper 2631 is fixed to the inner wall of the second fixed sleeve 2621 and can extend into the space between the second rotating member 261 and the third rotating member 262 through the third rotating member 262. The second fixed sleeve 2621 supports the second stopper 2631. In other embodiments, the second guide portion 2632 and the second stop portion 2633 can also be separately provided from the second rotating member 261.

[0282] Referring to FIGS. 40 and 42, in some embodiments, the second rotating member 261 is provided with a second notch 2611, one side wall of the second notch 2611 forms a second guide surface 26321, and the other side wall of the second notch 2611 forms a second stop surface 26331. The second stop member 2631 protrudes into the second notch 2611 and abuts against the second stop surface 26331, and can be retracted into the third rotating member 262 under the pushing action of the second guide surface 26321. The first notch 232 is opposite to the second notch 2611 in orientation. The second guide surface 26321 is an arc-shaped surface protruding towards the third rotating member 262, and is smoothly connected with the outer wall of the second rotating member 261, and the guide rotation direction of the second guide surface 26321 is opposite to that of the first guide surface 25221. In the first set direction, the second guide surface 26321 and the second stop surface 26331 are arranged in sequence, so as to ensure that the second rotating member 261 relatively rotates with the third rotating member 262 when the blade shaft 23 rotates in the first set direction, and the second rotating member 261 moves along with the conveying screw 24. When the blade shaft 23 rotates in the reverse direction, the third rotating member 262 drives the second rotating member 261 to rotate in the first set direction synchronously, and the second rotating member 261 provides a driving force for the rotation of the conveying screw 24.

[0283] Referring to FIGS. 33 and 34, in combination with FIG. 35, in some embodiments, the second transmission assembly 26 further includes a fourth rotating member 264 and a fifth rotating member 265. The fourth rotating member 264 is coaxially fixed on the blade shaft 23 and is arranged axially spaced apart from the third rotating member 262 along the blade shaft 23. One side of the fifth rotating member 265 is engaged with the fourth rotating member 264, and the other side is engaged with the third rotating member 262. The rotation axis of the fifth rotating member 265 is arranged perpendicularly to the rotation axis of the fourth rotating member 264. When the driving member 20 drives the blade shaft 23 to rotate, the fourth rotating member 264 rotates synchronously, and the third rotating member 262 is driven by the fifth rotating member 265 to rotate in the reverse direction, so that the rotation direction of the third rotating member 262 is opposite to that of the blade shaft 23. It should be noted that the fifth rotating member 265 can be rotatably installed in the ice maker 2 by means of a rotating shaft or the like.

[0284] In some embodiments, the first rotating member 251 and the second rotating member 261 are both bearings. The third rotating member 262 has at least a gear portion for engaging with the fifth rotating member 265. The third rotating member 262, the fourth rotating member 264, and the fifth rotating member 265 are all bevel gears.

[0285] In some embodiments, the first rotating member 251 and the second rotating member 261 can be integrally formed and connected in a sleeve-like structure, coaxially sleeved on the blade shaft 23, and one end of the sleeve is inserted into the third rotating member 262, and the two ends of the conveying screw 24 are connected to the two ends of the sleeve, respectively.

[0286] In some embodiments, more adjustable mechanical components or electronic control systems can be added to the second transmission assembly, such as a servo motor to control the relative motion between the second rotating member 261 and the third rotating member 262, so that the rotation of the blade shaft 23 and the conveying screw 24 is more accurate. This adjustment mechanism can be adjusted according to the different characteristics of the ice blocks (such as hardness, size, etc.), to optimize the effect of ice crushing or ice making operation. A variable speed drive design can be introduced, so that the transmission assembly (especially the third rotating member 262 and the fourth rotating member 264) can adjust the rotation speed according to the needs under different loads or use conditions, to provide higher flexibility. For example, when the blade shaft 23 rotates, the rate of ice crushing or ice making can be adjusted by the variable speed drive system to ensure the working efficiency under different conditions. Rolling bearings can be used, especially at the connection between the first rotating member 251, the second rotating member 261 and the third rotating member 262. In addition, self-lubricating technology can be introduced into the transmission system to ensure that the parts are always well lubricated during long-term operation, thereby reducing friction, reducing power consumption and prolonging the life of the parts. An overload protection design can be added to the transmission system, which automatically stops or reverses when the system detects that the blade shaft 23 or the conveying screw 24 encounters abnormal resistance or excessive load during operation to protect the equipment from being damaged. For example, the third rotating member 262 and the fourth rotating member 264 can be designed to have an overload disconnect function, which automatically disconnects or reverses when the system is overloaded to avoid damage. An external mechanical protective cover is added, especially to parts that are easily contacted by the transmission system, such as the connection between the second rotating member 261 and the third rotating member 262. This protective design can effectively prevent users from accidentally contacting high-speed rotating parts during operation, improving the safety of the equipment.

[0287] The working process of the present application is as follows:

[0288] When ice crushing is needed, the driving member 20 drives the ice cutter shaft 23 to rotate in a first set direction, the ice cutter shaft 23 drives the conveying screw 24 to rotate in the first set direction synchronously through the first transmission assembly 25, the ice blocks are conveyed to the ice outlet 281 through the conveying screw 24, and the ice is crushed through the ice crushing cutter 231 at the end of the ice cutter shaft 23; at this time, the second transmission assembly 26 does not drive the conveying screw 24. When ice crushing is not needed, the driving member 20 drives the ice cutter shaft 23 to rotate reversely, the ice cutter shaft 23 drives the conveying screw 24 to rotate in the first set direction through the second transmission assembly 26, the ice blocks are conveyed to the ice outlet 281 through the conveying screw 24, at this time, the ice crushing cutter 231 at the end of the ice cutter shaft 23 does not perform the ice crushing function, and the first transmission assembly 25 does not drive the conveying screw 24.

[0289] In the foregoing embodiments, by setting the synchronous rotation or relative rotation of the conveying screw and the ice cutter shaft, the complex ice outlet selector is avoided, and the structural simplification and operation efficiency of the ice maker are improved. The following embodiments optimize the installation mode of the ice maker, and improve the connection structure. Through the inclined design of the first connection part and the second connection part, the stable connection of the shell and the mounting seat is realized, and the installation stability of the ice maker in the refrigeration compartment is further improved.

[0290] Referring to FIGS. 43 and 44, the refrigerator provided in the embodiments of the present application includes a cabinet 1 and an ice maker 2. The cabinet 1 is provided with a refrigeration compartment 121, and the refrigeration function of the refrigerator is realized through the refrigeration compartment 121. The ice maker 2 is arranged in the refrigeration compartment 121, and the ice making function of the refrigerator is realized through the ice maker 2.

[0291] Referring to FIGS. 43 and 44, in some embodiments, the cabinet 1 is further provided with a freezing compartment 122, and the freezing function of the refrigerator is realized through the freezing compartment 122. The cabinet 1 is generally in the form of a rectangular cuboid frame structure. The cabinet 1 includes a cabinet shell 13 and a cabinet liner 12. The cabinet liner 12 is arranged in the cabinet shell 13, and an installation space is formed between the cabinet liner 12 and the cabinet shell 13 for installing other components and structures of the refrigerator and forming a foamed thermal insulation layer. The inside of the cabinet liner 12 forms a storage space for storing food. The cabinet shell 13 provides protection and support for the cabinet liner 12.

[0292] Referring to FIGS. 43 and 44, the inside of the cabinet liner 12 forms a refrigeration chamber, which is divided into a refrigeration compartment 121 and a freezing compartment 122. The refrigeration compartment 121 is located at the upper part of the cabinet liner 12, and the freezing compartment 122 is located at the lower part of the cabinet liner 12. It should be noted that the positions of the refrigeration compartment 121 and the freezing compartment 122 can also be arranged in reverse order. One side of the refrigeration compartment 121 and one side of the freezing compartment 122 are both provided with a taking and placing opening for conveniently taking and placing articles. A door body is connected to the taking and placing opening. The door body is connected to the cabinet 1 in a rotatable or sliding manner to open or close the taking and placing opening.

[0293] In some embodiments, the refrigerator further comprises a refrigeration system (not shown in the figure) and an air supply system (not shown in the figure), which are electrically connected with the power supply assembly for supplying electricity to the components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0294] The refrigeration system is installed in the cabinet 1 and is used to provide cold air to the refrigeration chamber inside the cabinet 12. The refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, a return air pipe, a throttling device and other components, and a refrigerant. Each component is distributed at different positions of the cabinet 1 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are turned on, the compressor starts to work, the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and after being compressed into high-temperature and high-pressure refrigerant gas by the compressor, it is discharged to the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the outside environment through the condenser, the temperature drops, and it is gradually cooled into a normal-temperature and high-pressure refrigerant saturated vapor, and then into a refrigerant saturated liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered to remove water and impurities through the drying filter and then flows into the throttling device, and the throttling device is throttled to reduce the pressure, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. The evaporation process is as follows: the normal-temperature and low-pressure wet vapor enters the evaporator, starts to absorb heat to vaporize, reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and makes the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor, and the above process is repeated, the state of the refrigerant changes to convert energy, the heat in the refrigerator is transferred to the air outside the cabinet, thereby realizing the refrigeration cycle of the refrigerator.

[0295] An air supply system is installed in the cabinet 1 to provide power for the cold air flow; the air supply system generally includes a fan and an air supply air duct defined in the cabinet 1, in some embodiments, the air inlet end of the air supply air duct is arranged close to the fan, and the air outlet end of the air supply air duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply air duct is arranged close to the fan, and the air inlet end of the air supply air duct is arranged away from the fan. The cabinet 1 also defines an air duct cavity, which is in communication with the air supply air duct and the refrigeration cavity in the cabinet 12, so that the air supply air duct is in communication with the refrigeration cavity through the air duct cavity; it should be noted that the cabinet 12 is provided with an air outlet, which is used to communicate the air duct cavity and the refrigeration cavity. The cold air generated by the refrigeration system is introduced into the air duct cavity through the air supply air duct by the operation of the fan, and flows to the refrigeration cavity through the air outlet to refrigerate the refrigeration cavity. It should be noted that in some embodiments, the air outlet is arranged on the side wall of the cabinet 12 opposite to the opening of the refrigeration cavity or on the side wall adjacent to the opening of the refrigeration cavity; it should be noted that the refrigeration system and the air supply system belong to the related technology in the art, which will not be described here.

[0296] In some embodiments, on-demand ice making can be achieved by introducing a timer or scheduling system. Automatic adjustment according to ice demand (e.g. daily or weekly) can avoid unnecessary ice production and reduce energy consumption. Scale or mold may accumulate in the ice making box. By designing an automatic cleaning or self-cleaning mechanism (e.g. periodically activating a water flow flushing system), the hygiene and efficient operation of the ice making box can be ensured. The ice forming system is optimized to achieve ice blocks of different densities or shapes (such as thin ice, coarse ice or crushed ice) by adjusting water flow, time or cooling rate to meet different user needs. Considering the problem of odor or bacterial growth in the refrigerator, an air purifier (such as using negative ions, ultraviolet lamps or activated carbon filters) can be introduced to help purify the air in the refrigerator and keep the food fresh.

[0297] The ice maker 2 is arranged in the refrigeration compartment 121 and is used for ice making operation. The ice maker 2 can be a direct-cooling ice maker 2 or an air-cooled ice maker 2. Referring to FIGS. 45, 47 and 54, in some embodiments, the ice maker 2 comprises a shell 21 arranged in the refrigeration compartment 121, and the outer wall of the shell 21 is provided with a first connecting portion 3, and the first connecting portion 3 is provided with a first connecting hole 312 through which a fastener passes; the cabinet 1 is embedded with a mounting seat 5, and the mounting seat 5 is located outside the refrigeration compartment 121; the mounting seat 5 has a second connecting portion 51, and the second connecting portion 51 is provided with a second connecting hole 5111, and the center axis of the second connecting hole 5111 is parallel to the center axis of the first connecting hole 312, and the center axis of the first connecting hole 312 and the center axis of the second connecting hole 5111 are both arranged obliquely and form an angle with the horizontal plane; the first connecting portion 3 at least partially penetrates the outer wall of the refrigeration compartment 121 and is connected with the second connecting portion 51, or the second connecting portion 51 at least partially penetrates the outer wall of the refrigeration compartment 121 and is connected with the first connecting portion 3, and the first connecting hole 312 and the second connecting hole 5111 are opposite to each other; and the fastener is assembled in the first connecting hole 312 and the second connecting hole 5111 to connect the shell 21 and the mounting seat 5, thereby achieving the mounting and fixing of the ice maker 2 in the refrigeration compartment 121.

[0298] Since the center axis of the first connecting hole 312 and the center axis of the second connecting hole 5111 are both arranged obliquely, when the fastener is assembled in the first connecting hole 312 and the second connecting hole 5111, the fastener is inserted obliquely into the first connecting hole 312 and the second connecting hole 5111, and the fastening force of the fastener has a horizontal component and a vertical component, which can simultaneously achieve the vertical and horizontal fastening of the shell 21, reinforce the connection between the shell 21 and the refrigeration compartment 121, thereby ensuring the mounting stability of the ice maker 2 in the refrigeration compartment 121 and avoiding the fastener from falling off after long-term use of the ice maker 2. Moreover, the same fastener can be used to simultaneously achieve horizontal and vertical fastening, which can significantly reduce the number of fasteners used and save disassembly and assembly time.

[0299] In some embodiments, a rubber gasket or other vibration-absorbing material can be added between the first connecting part 3 and the second connecting part 51. This can effectively reduce the impact of the vibration generated by the ice maker during operation on the connecting part, further improve the stability of the installation, and reduce the risk of loosening or damage due to long-term vibration. Adjustable structures can be designed in the first connecting part 3 and the second connecting part 51, allowing users to adjust the connection angle or position according to actual needs, enhancing the flexibility of installation. This can ensure that the ice maker can be flexibly installed in different models of refrigerators. By designing an oval or multi-hole connecting hole, the fastener has more adjustment space during installation. This design can increase the fault tolerance of the connecting hole and reduce the mismatch problem caused by manufacturing errors or position deviation. An enhanced thread design is used in the connecting hole to increase the contact area of the thread, thereby increasing the fastening force and effectively preventing loosening over time. A maintenance interface can be designed on the shell 21, so that when the device fails, it can be easily repaired or detected. For example, a power supply interface, a cold air pipeline interface, etc. that can be easily disassembled are designed to reduce the workload and time during maintenance.

[0310] Referring to Figures 53 and 56, in some embodiments, multiple first connecting holes 312 and second connecting holes 5111 are provided, with each first connecting hole 312 corresponding to each second connecting hole 5111. Multiple fasteners are respectively assembled into the first connecting holes 312 and the corresponding second connecting holes 5111 to reinforce the connection between the housing 21 and the mounting base 5. The fasteners can be screws, bolts, etc. In other embodiments, fasteners are assembled into some of the first connecting holes 312 and the corresponding second connecting holes 5111 to connect the housing 21 and the mounting base 5, while other parts of the first connecting holes 312 and the corresponding second connecting holes 5111 serve as spare mounting holes, so that if the original holes become unusable after disassembly, the spare mounting holes can be used for fixing.

[0311] Referring to Figures 55 and 56, in some embodiments, the second connecting portion 51 is provided with a connecting position 511, one wall of which is inclined. A second connecting hole 5111 is formed on the inclined wall of the connecting position 511, facilitating the manufacturing of the second connecting hole 5111.

The end face of the mounting portion 5112 away from the inclined wall is flush with the surface of the second connecting portion 51. It should be noted that when the mounting portion 5112 is provided, the second connecting hole 5111 on the second connecting portion 51 is a through hole, which facilitates the insertion of fasteners into the mounting portion 5112; when the mounting portion 5112 is not provided, the second connecting hole 5111 on the second connecting portion 51 can be set as a blind hole to prevent fasteners from penetrating the second connecting portion 51 and entering the foamed insulation layer. In some embodiments, the connecting position 511 can be a groove.

[0313] In some embodiments, elastic adjustment devices can be added between the first connecting hole 312 and the second connecting hole 5111, which can automatically adjust the slight deviation of the hole position after long-term use, ensure that the connecting hole can still be accurately docked, and avoid poor fit caused by production errors. In the design of the groove wall, the transition of the inner arc and the connecting surface is optimized to reduce the possibility of misalignment of the connection, thereby ensuring that the fastener can smoothly enter when connected, and avoiding uneven stress or material deformation. The connecting position 511 and the first connecting part 3 can be designed as an integrated structure, that is, the groove is designed to directly fit with the first connecting part 3, rather than a separate component. This way will reduce the number of components during assembly, improve assembly efficiency, and enhance the stability of the connection and the overall structural strength. Reinforcing ribs are added around the connecting position 511 and its surrounding area, especially at the connecting points that bear larger loads. These reinforcing ribs can significantly improve the anti-deformation ability of the component, especially during installation, to avoid deformation of the connecting position due to uneven force.

[0316] Referring to FIGS. 53 and 56, in some embodiments, the positioning portion 4 is provided with a protrusion 411 on the side away from the shell 21, which extends outwardly and protrudes from the positioning portion 4. The protrusion 411 and the outer wall of the shell 21 are spaced apart to form a clamping portion 4111, wherein the protrusion 411 and the outer wall of the shell 21 serve as the groove walls of the clamping portion 4111, and the positioning portion 4 serves as the groove bottom of the clamping portion 4111. The slot of the positioning seat 52 is provided with a retaining edge 522 to form a clamping portion 521, and the retaining edge 522 covers part of the slot of the positioning seat 52. The retaining edge 522 and the groove bottom surface of the positioning seat 52 form a clamping space 5221 for clamping the protrusion 411. When the positioning portion 4 is embedded in the positioning seat 52, the protrusion 411 is embedded in the clamping space 5221, and the retaining edge 522 is embedded in the clamping portion 4111, thereby ensuring the positioning accuracy of the installation position of the shell 21. In addition, the positioning seat 52 forms a stop action on the positioning portion 4 in the transverse direction, thereby preventing the shell 21 from moving in the transverse direction. The protrusion 411 and the retaining edge 522 stop each other in the vertical direction, thereby preventing the shell 21 from moving in the longitudinal direction, so that the shell 21 is relatively fixed with the mounting seat 5, and the fastener is convenient to install. In some embodiments, the positioning seat 52 can be a positioning groove, and the clamping portion 4111 can be a clamping groove.

[0317] It should be noted that in other embodiments, the clamping portion 4111 can also be directly formed on the positioning portion 4, and the clamping portion 521 is in the form of a plate and is fixed to the groove wall of the positioning seat 52.

[0318] In some embodiments, the first connecting portion 3 and the frame 211 can be separately provided or integrally formed. The positioning portion 4 and the frame 211 can be separately provided or integrally formed.

[0319] In some embodiments, the clamping portion 521 and the clamping portion 4111 can be automatically locked after assembly by increasing the self-locking design. For example, the clamping portion 521 can be designed with a slope shape, which is automatically locked by an internal spring or a clamping pin after insertion, thereby preventing the clamping portion from loosening during use. If the positioning portion 4 needs to withstand a large pressure or may be deformed after long-term use, a metal reinforcing structure such as a metal support ring or a reinforcing plate can be used in the key area of the positioning portion 4, especially in the clamping portion 4111. This will significantly improve the durability and anti-deformation ability of the positioning portion 4.
