Technical Field

[0002] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator. Background Technology

[0003] A refrigerator is a device for long-term food preservation, keeping food at a low temperature to ensure people's daily dietary health. It has become a very important appliance in people's lives. As people's living standards continue to improve, they often add ice to their drinks to lower the temperature and achieve a refreshing taste. Refrigerators themselves create an environment suitable for food preservation by lowering the temperature. The low temperature environment inside a refrigerator is conducive to the production and storage of ice, so the market demand for refrigerators with ice makers is gradually increasing.

[0005] This application provides a refrigerator for improving the versatility of ice maker parts, thereby reducing production costs.

[0006] On one hand, embodiments of this application provide a refrigerator, including:

[0007] The box body includes a box shell and an inner liner, the inner liner is disposed inside the box shell, and a refrigeration chamber is provided inside the inner liner;

[0008] The door, connected to the housing, is used to open or close the refrigeration chamber; and

[0009] An ice maker is disposed in the refrigeration chamber; the ice maker includes a water injection unit, a frame, and an ice grid; the water injection unit is connected to the inner liner, the frame is mounted on the water injection unit, the ice grid is installed inside the frame, and the water injection unit is used to inject water into the ice grid;

[0010] The water injection unit comprises at least two units, each of which includes an end cap and a water injection pipe. The end caps are arranged sequentially on the inner liner, and adjacent end caps are detachably connected. Each water injection pipe is connected to each end cap in a corresponding manner.

[0011] On the other hand, this application provides a refrigerator, including a cabinet, a door, and an ice maker. The cabinet includes a shell and an inner liner, the inner liner being disposed within the shell, and a refrigeration chamber being provided inside the inner liner.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0041] The refrigerator 100 provided in this application can have various implementation forms. This application provides some exemplary embodiments to illustrate the specific structure of the refrigerator 100, but does not constitute a limitation on this application.

[0042] In one exemplary embodiment, the refrigerator 100 includes a cabinet 10.

[0043] The directions described in the text are based on the direction in which the user faces the refrigerator 100. The left and right sides are distinguished by the direction in which the user faces the refrigerator 100. The side of the refrigerator 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The top and bottom sides of the refrigerator 100 when it is generally working normally are defined to distinguish the top and bottom.

[0044] As shown in Figure 1, the cabinet 10 is used to form the overall appearance of the refrigerator 100. The cabinet 10 is roughly in the shape of a cuboid frame. The top and bottom of the cabinet 10 are opposite ends. The height direction of the cabinet 10 is from the top to the bottom. The left and right sides of the cabinet 10 are opposite sides. The width direction of the cabinet 10 is from the left to the right. The front and rear sides of the cabinet 10 are opposite sides. The thickness direction of the cabinet 10 is from the front to the rear. The first direction is the width direction of the cabinet 10, and the second direction is the height direction of the cabinet 10.

[0045] The cabinet 10 includes a shell 11 and an inner liner 12. The inner liner 12 is disposed within the shell 11, forming an installation space between them for installing other components of the refrigerator 100 and forming a foamed insulation layer. The inner liner 12 may include a refrigerator inner liner and a freezer inner liner. The refrigerator inner liner and the freezer inner liner may be divided into multiple compartments for storing different foods or household items. Each compartment may be separated by a glass shelf or by a storage box. In some embodiments, the cabinet 10 may include multiple refrigerator inner liners and freezer inner liners; for example, as shown in FIG1, the cabinet 10 may include two freezer inner liners.

[0046] The inner liner 12 has a refrigeration chamber 15 inside, which is used to place goods, food, or daily necessities. The refrigeration chamber 15 has an opening facing the front of the box body 10. The refrigeration chamber 15 can be in a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment.

[0047] In some embodiments, the refrigerator 100 further includes a door 20 disposed at the cavity opening of the cabinet 10. The door 20 is a straight plate disposed on the front side of the cabinet 10, and the door 20 is closably connected to the cabinet 10 to open or close the refrigeration cavity 15.

[0048] The refrigerator 100 also includes a refrigeration system (not shown) and an air supply system (not shown), which are electrically connected to a power supply component. The power supply component is used to supply power to the various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0049] The refrigeration system is installed inside the cabinet 10 and is used to supply cold air to the refrigeration chamber 15. A refrigeration system typically refers to a closed system composed of components such as a compressor, evaporator, condenser, dryer filter, return pipe, and throttling device, along with refrigerant. Each component is distributed in different positions within the cabinet 10 according to its structural characteristics to meet its corresponding functional requirements. The working process of the refrigeration system mainly includes compression, condensation, throttling, and evaporation. The compression process is as follows: After the power cord of the refrigerator 100 is plugged in, with the thermostat contacts closed, the compressor starts working. Low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into high-temperature, high-pressure refrigerant gas before being discharged into the condenser. The condensation process is as follows: The high-temperature, high-pressure refrigerant gas exchanges heat with the external environment through the condenser, condensing into a high-temperature, high-pressure liquid. The throttling process is as follows: The condensed high-temperature, high-pressure refrigerant liquid is filtered through the dryer filter to remove moisture and impurities before flowing into the throttling device. The throttling device reduces the pressure, turning the refrigerant into a low-temperature, low-pressure liquid. Evaporation process: Low-temperature, low-pressure liquid enters the evaporator, absorbs heat and vaporizes, lowering the temperature of the evaporator and its surroundings, thus achieving refrigeration. This process also transforms the refrigerant into low-temperature, low-pressure vapor. The refrigerant exiting the evaporator returns to the compressor, repeating the above process. Through the change in the refrigerant's state, energy is converted, transferring heat from inside the refrigerator 100 to the outside air, thereby achieving the refrigeration cycle of the refrigerator 100.

[0050] An air supply system is installed in the housing 10 to provide power for the flow of cold air. The air supply system generally includes a fan and an air supply duct defined within the housing 10. In some embodiments, the air inlet of the air supply duct is located close to the fan, and the air outlet of the air supply duct is located away from the fan. In other embodiments, the air outlet of the air supply duct is located close to the fan, and the air inlet of the air supply duct is located away from the fan. The housing 10 also defines an air duct cavity, which is connected to the air supply duct and the cooling chamber 15, so that the air supply duct is connected to the cooling chamber 15 through the air duct cavity. It should be noted that the inner liner 12 has an air outlet, which is used to connect the air duct cavity and the cooling chamber 15. The cold air generated by the cooling system is drawn into the air duct cavity by the operation of the fan and flows from the air outlet to the cooling chamber 15 to cool the cooling chamber 15. It should also be noted that in some embodiments, the air outlet is located on the side wall opposite to the opening of the inner liner 12 and the cooling chamber 15, or on the side wall adjacent to the opening of the inner liner 12 and the cooling chamber 15.

[0051] In some embodiments, the refrigerator 100 further includes a refrigeration unit 30. The ice maker 30 is configured to produce ice. As shown in Figures 2 and 3, the ice maker 30 is disposed within a refrigeration chamber 15. The ice maker 30 includes a water injection unit 31. The water injection unit 31 is connected to an inner liner 12. The inner liner 12 may be a freezing liner, serving as a space for holding frozen food. The inner liner 12 has an opening into which the water injection unit 31 is embedded and closes the opening.

[0052] The water injection unit 31 can be multiple, and each water injection unit 31 includes an end cap 311 and a water injection pipe 312. That is, for the ice maker 30, the number of end caps 311 is at least two, and the number of water injection pipes 312 is also at least two. The end caps 311 are arranged sequentially on the inner liner 12, and adjacent end caps 311 are detachably connected; the number of water injection pipes 312 is the same as the number of end caps 311, and each water injection pipe 312 is connected to each end cap 311 in a one-to-one correspondence. By modularizing and standardizing the water injection unit 31, the corresponding number of end caps 311 can be selected and assembled according to different types of refrigerators or different customer needs, that is, the corresponding number of water injection pipes 312 are selected at the same time. Each water injection pipe 312 can correspond to different specifications of ice trays to achieve different ice-making requirements. When producing different types of refrigerators, the end cap 311 structure between water injection units 31 of different specifications can be interchanged, ensuring standardized mass production and thus reducing production costs.

[0053] In some embodiments, the ice maker 30 is installed on the inner liner 12, and the refrigeration chamber 15 is a freezing temperature environment, thereby utilizing the low temperature environment of the refrigeration chamber 15 to condense the water in the ice tray 33 into ice cubes.

[0054] In another embodiment, the ice maker 30 can also be installed on the door 20. The ice maker 30 installed on the door 20 can be used to remove ice without opening the door 20, making it more convenient to use and improving the user experience.

[0055] In another embodiment, the ice maker 30 can also be set in the refrigeration chamber 15 in a refrigeration temperature environment or a normal temperature environment. In this case, the water in the ice grid 33 cannot be frozen into ice by relying on the temperature environment in the refrigeration chamber 15. Therefore, a condenser tube needs to be installed on the ice grid 33 to reduce the temperature of the ice grid 33, thereby causing the water in the ice grid 33 to freeze into ice.

[0056] In some embodiments, the ice maker 30 further includes a frame 32 and an ice tray 33. The frame 32 is mounted on a water injection unit 31, and the ice tray 33 is hinged within the frame 32. The water injection unit 31 is used to inject water into the ice tray 33. There can be multiple frames 32 and ice trays 33, and each water injection unit 31 is provided with one frame 32 and one ice tray 33.

[0057] In one embodiment, the end cap 311 is connected and fixed to the inner liner 12, and the end cap 311 is used to fix the water injection pipe 312 to the inner liner 12. The frame 32 is detachably connected to the end cap 311, and the frame 32 is suspended in the refrigeration chamber 15 through the end cap 311. The end cap 311 is a supporting component of the ice maker 30. During the assembly process, the end cap 311 is connected to the inner liner 12, and then the end cap 311 is fixed in the designated position of the inner liner 12 through a foaming process. Then, the frame 32 of the ice maker 30 is detachably suspended on the end cap 311, thus realizing the installation of the ice maker 30 in the refrigeration chamber 15.

[0058] In some embodiments, adjacent sides of adjacent end caps 311 are detachably connected. This detachable connection can be a snap-fit ​​connection, a plug-in structure, or other connection method. For example, one end cap 311 has a hook-up portion on its side, and the other end cap 311 has a snap-fit ​​portion on its side, with the snap-fit ​​portion forming a groove. The hook-up portion and the snap-fit ​​portion engage with each other to achieve a detachable connection.

[0059] As shown in Figure 6, the end cap 311 includes a connecting portion 3111, a snap-fit ​​portion 3112, a supporting portion 3113, and a hook-up portion 3114. The connecting portion 3111 is connected to the inner liner 12 and is generally straight. The snap-fit ​​portion 3112 and the supporting portion 3113 are disposed opposite each other on both sides of the connecting portion 3111. The snap-fit ​​portion 3112 is straight and extends along a second direction. The extending plane of the snap-fit ​​portion 3112 is perpendicular to the extending plane of the connecting portion 3111. The supporting portion 3113 is straight and is disposed on the side of the connecting portion 3111 away from the snap-fit ​​portion 3112. The supporting portion 3113 is parallel to the snap-fit ​​portion 3112. The hook portion 3114 extends from the end of the supporting portion 3113 away from the connecting portion 3111 towards the connecting portion 3111. The hook portion 3114 is used to hook onto the snap-fit ​​portion 3112 of adjacent end caps 311. That is, the detachable connection between two adjacent end caps 311 is achieved by inserting the snap-fit ​​portion 3112 of one end cap 311 between the supporting portion 3113 and the hook portion 3114 of the other end cap 311. The snap-fit ​​portions 3112 and supporting portions 3113 of the two adjacent end caps 3111 abut against each other, and the hook portion 3114 hooks onto the snap-fit ​​portion 3112 to connect the two adjacent end caps 3111. In this embodiment, the hook portion 3114 is L-shaped, with one end connected to the supporting portion 3113 and the other end extending towards the connecting portion 3111.

[0060] In some embodiments, the buckle portion 3112 is provided with a fixing hole 3115. The fixing hole 3115 is groove-shaped and located on the side of the buckle portion 3112 away from the joint portion 3111. The fixing hole 3115 can also be configured as a through hole extending through the buckle portion 3112 in a first direction. The abutment portion 3113 is provided with a fixing block 3116. The fixing block 3116 is protruding and located on the side of the abutment portion 3113 away from the joint portion 3111. The fixing hole 3115 and the fixing block 3116 are positioned correspondingly. When two adjacent end caps 311 are engaged, the fixing block 3116 of one end cap 311 is inserted into the fixing hole 3115 of the other end cap 3111 to secure the buckle portion 3112 between the abutment portion 3113 and the hook portion 3114, thereby achieving a snap-fit ​​fixation between the two adjacent end caps 311 and making the disassembly and assembly operations more convenient.

[0061] In some embodiments, a plurality of fixing holes 3115 are provided on the same end cap 311, and each fixing hole 3115 is spaced apart along the buckle portion 3112; the number of fixing blocks 3116 is the same as the number of fixing holes 3115, and they correspond one-to-one. By providing a plurality of fixing holes 3115 and fixing blocks 3116, the reliability of the connection between two adjacent end caps 311 is improved.

[0062] In some embodiments, the number of hook portions 3114 is twice that of fixing blocks 3116. The hook portions 3114 are arranged opposite to the two sides of the fixing blocks 3116 to ensure that when two adjacent end caps 311 are snapped together, the pressure applied by the hook portions 3114 to the position where the fixing hole 3115 is provided on the buckle portion 3112 is balanced on both sides, thereby ensuring the reliability of the fixing block 3116 being inserted into the fixing hole 3115.

[0063] In actual use, for processing or installation, both the snap-fit ​​part 3112 and the abutment part 3113 can be provided with a discontinuous groove. There is no restriction on whether the snap-fit ​​part 3112 and the abutment part 3113 are uninterrupted plate structures. It is only necessary to ensure that when two adjacent end caps 311 are spliced, the snap-fit ​​part 3112 and the abutment part 3113 abut against each other, and the fixing block 3116 on the abutment part 3113 is inserted into the fixing hole 3115 on the snap-fit ​​part 3112 for locking and fixing.

[0064] In some embodiments, as shown in FIG4, the frame 32 includes a mounting bracket 321 and a locking block 322. Multiple frames 32 are provided, with the mounting brackets 321 arranged sequentially at intervals on the inner wall of the inner liner 12, and the locking blocks 322 disposed between adjacent mounting brackets 321 to fix adjacent mounting brackets 321.

[0065] As shown in Figure 9, the mounting frame 321 is provided with a latch 3213 and a socket 3214. As shown in Figures 8 and 11, the locking block 322 includes a base part 3221, a latching part 3222, and a pin part 3223. Both the latching part 3222 and the pin part 3223 are connected to the base part 3221. The latching part 3222 is engaged into the latch 3213 in a first direction, and the pin part 3223 is inserted into the socket 3214 in a second direction. By also setting the frame 32 as a modular structure, the interior of the mounting frame 321 is used to install the ice-making grid 33 to provide space for water to condense into ice. By setting multiple mounting frames 321, multiple ice-making units are formed. The number of mounting frames 321 to be assembled can be selected according to the needs, thereby achieving control over the number of ice-making units. It is not necessary to produce mounting frames 321 of various specifications, thereby reducing processing costs.

[0066] In some embodiments, the mounting bracket 321 is suspended inside the refrigeration chamber 15. The mounting bracket 321 is generally hollow and rectangular, as shown in FIG4. The top of the mounting bracket 321 is connected to the joint 3111 of the end cover 311. The opening of the mounting bracket 321 faces downward to facilitate the discharge of ice. The ice falls under its own weight into the ice storage box 13 below the mounting bracket 321 for unified collection. In this embodiment, the mounting bracket 321 is connected and fixed to the end cover 311 by screws.

[0067] In some embodiments, as shown in FIG5, a boss 3211 is provided on the outer side of the mounting bracket 321. The boss 3211 is provided on the outer side wall of the bottom of the mounting bracket 321, and the boss 3211 is elongated. The bosses 3211 are arranged opposite each other on both sides of the mounting bracket 321 in the first direction to ensure that when the mounting brackets 321 are arranged side by side in sequence, a space for the locking block 322 to be installed is formed between two adjacent mounting brackets 321 through the bosses 3211. In this embodiment, the boss 3211 forms a mounting surface 3211a parallel to the top surface of the mounting bracket 321, and the insertion port 3214 is provided on the mounting surface 3211a of the boss 3211, so that the insertion port 3214 is formed in the second direction. The latch 3213 is provided on the side wall of the mounting bracket 321 in the first direction.

[0068] In some embodiments, as shown in Figures 8 and 11, the base portion 3221 of the locking block 322 is generally square in shape. When the locking block 322 is connected to the mounting bracket 321, the base portion 3221 abuts against the boss 3211. The boss 3211 provides positioning support for the base portion 3221, ensuring the reliability of the connection between the locking block 322 and the mounting bracket 321.

[0069] The pin portion 3223 and the latch portion 3222 are respectively disposed on both sides of the base portion 3221 in the second direction. During installation, as shown in Figures 12 and 13, the locking block 322 is inserted between two adjacent mounting brackets 321 along the second direction, such that the pin portion 3223 inserts into the socket 3214 on the boss 3211, and the latch portion 3222 engages with the socket 3213 on the side wall, thereby fixing the locking block 322 to the two adjacent mounting brackets 321. During removal, the locking block 322 can be pulled out along the second direction. The disassembly and assembly of the locking block 322 are simple, improving disassembly and assembly efficiency. In this embodiment, each locking block 322 is provided with two mutually offset latching parts 3222 and two mutually offset pin parts 3223. The latching parts 3222 and the pin parts 3223 are respectively arranged opposite to each other on both sides of the base part 3221 in the first direction to ensure that the locking block 322 simultaneously fixes the mounting brackets 321 on both sides.

[0070] When connecting two adjacent mounting brackets 321, one of the latching parts 3222 is connected to one of the mounting brackets 321, and the other latching part 3222 is connected to the other adjacent mounting bracket. Similarly, one of the pins 3223 is connected to one of the mounting brackets 321, and the other pin 3223 is connected to the other adjacent mounting bracket. The two adjacent mounting brackets 321 are connected by the locking block 322.

[0071] As shown in Figures 8 and 11, the latching part 3222 includes a spring piece 32221 and a latching block 32222. The spring piece 32221 is a straight plate extending along the second direction and is connected to the base part 3221. The latching block 32222 protrudes from one side of the spring piece 32221 in the first direction. The latching block 32222 is inserted into the latching slot 3213, and the spring piece 32221 elastically presses the latching block 32222 into the latching slot 3213 to achieve the latching part 3222 and the latching slot 3213 engaging at the position. During installation, after the locking block 322 is inserted to a preset depth, that is, when the base part 3221 abuts against the boss 3211, the locking block 32222 will be inserted into the slot 3213 to secure it. During disassembly, pressing the spring piece 32221 causes the locking block 32222 to disengage from the slot 3213, and the locking block 322 can be pulled out. The overall installation and disassembly operation is simple and convenient.

[0072] The latching part 3222 also includes a rib 32223. The rib 32223 is triangular and is located on the side of the spring piece 32221 facing away from the latching block 32222. The rib 32223 connects the base part 3221 and the spring piece 32221 respectively. The rib 32223 is used to improve the connection reliability between the base part 3221 and the spring piece 32221, thereby avoiding breakage due to the load being concentrated at the joint position of the spring piece 32221 and the base part 3221 during repeated pressing of the spring piece 32221, and extending the service life of the locking block 322.

[0073] The pin portion 3223 extends in a straight plate shape along the second direction. The pin portion 3223 is located on the side of the base portion 3221 away from the spring piece 32221. During installation, with the base portion 3221 abutting against the boss 3211, the pin portion 3223 is inserted into the socket 3214 on the boss 3211. By inserting the pin portion 3223 into the socket 3214 along the second direction, the base portion 3221 abuts against the boss 3211. The weight of the locking block 322 itself helps to stably insert the pin portion 3223 into the socket. Within 3214, the reliability of the connection between the locking block 322 and the mounting bracket 321 is improved, so that the locking block 322 can constrain and fix the mounting bracket 321 on a plane perpendicular to the second direction. By inserting the latch 32222 into the slot 3213 along the first direction, the locking block 322 can constrain and fix the mounting bracket 321 on a plane perpendicular to the first direction. Then, through the cooperation of the pin part 3223 and the buckle part 3222, the locking block 322 can fix the mounting bracket 321 in the horizontal and vertical directions.

[0074] In some embodiments, the cross-sectional area of ​​the pin portion 3223 gradually decreases from the base portion 3221 toward the direction away from the base portion 3221, and the cross-sectional direction of the pin portion 3223 is a plane direction perpendicular to the second direction. By gradually decreasing the cross-sectional area of ​​the pin portion 3223, the pin portion 3223 is easier to insert into the socket 3214, thereby improving the installation efficiency of the locking block 322.

[0075] By setting the pin part 3223 and the buckle part 3222 on both sides of the base part respectively, when disassembling, pressing the spring piece 32221 separates the locking block 32222 from the bayonet 3213, and then pulling the locking block 322 upwards is sufficient. When assembling, the locking block 322 is inserted directly downwards. The disassembly and assembly operations are simple and improve the disassembly and assembly efficiency.

[0076] Referring to Figures 8 and 13, the locking block 322 also includes a positioning part 3224. This positioning part 3224 is connected to the base part 3221 and is located on the side of the base part 3221 near the latching part 3222. A positioning post 3212 is provided on the mounting bracket 321. The positioning post 3212 protrudes from the upper surface of the mounting bracket 321. The positioning post 3212 is cylindrical. In another embodiment, the positioning post 3212 may also be protruding. The positioning post 3212 passes through the positioning part 3224 along a second direction. By cooperating with the positioning post 3212 and the positioning part 3224, the installation position of the locking block 322 can be quickly positioned to improve the installation efficiency of the locking block 322. At the same time, by using the connection method of the positioning post 3212 passing through the positioning part 3224, the locking block 322 can constrain and fix the mounting frame 321 on a plane perpendicular to the second direction. Then, the positioning part 3224 and the pin part 3223 jointly fix the mounting frame 321, improving the reliability of the locking block 322 fixing the mounting frame 321.

[0077] As shown in Figure 8, the positioning part 3224 includes an extension block 32241 and a connecting block 32242. The extension block 32241 is elongated and extends along a second direction, and is connected to the base part 3221. The connecting block 32242 is elongated and extends along a first direction, and is located on the side of the extension block 32241 away from the base part 3221. The positioning part 3224 is T-shaped. Positioning holes 32245 are provided at both ends of the connecting block 32242. The positioning holes 32245 at both ends allow positioning posts 3212 on two adjacent mounting brackets 321 to pass through along the second direction, so as to connect the two adjacent mounting brackets 321 through the positioning part 3224.

[0078] In one embodiment, two extension blocks 32241 are provided, located on both sides of the connecting block 32242 facing the spring piece 32221, forming two legs of the connecting block 32242. The two extension blocks 32241 are spaced apart from each other, providing appropriate space for the insertion of the positioning post 3212, facilitating the engagement of the positioning hole 32245 with the positioning post 3212, and avoiding interference between the positioning post 3212 and the extension block 32241.

[0079] Both the latching part 3222 and the positioning part 3224 are connected to the base part 3221. The latching part 3222 is engaged into the slot 3213 in the first direction, and the positioning pin 3212 is inserted into the positioning part 3224 in the second direction. In some embodiments, the locking block 322 can be connected and fixed to the mounting bracket 321 by a combination of the positioning part 3224 and the latching part 3222. Alternatively, the locking block 322 can be connected and fixed to the mounting bracket 321 by a combination of the pin part 3223 and the latching part 3222. Both combinations can achieve multi-directional constraint and fixation of the locking block 322 on the mounting bracket 321, thereby ensuring the reliability of the connection between the locking block 322 and two adjacent mounting brackets 321.

[0080] In the above embodiment, the detachable connection between the two mounting brackets 321 is achieved by the locking block 322. In other embodiments, snap-fit ​​connection, locking connection, and other methods can also be used.

[0081] In some embodiments, as shown in Figures 9 and 10, the frame 32 is further provided with a water inlet 3215, and the water inlet pipe 312 has a water outlet. The water inlet 3215 corresponds to the water outlet of the water inlet pipe 312, and the water inlet pipe 312 injects water into the ice tray 33 through the water inlet 3215. The ice tray 33 is disposed in the mounting frame 321, and the ice tray 33 and the mounting frame 321 are rotatably connected. After the water in the ice tray 33 freezes into ice cubes, the ice cubes are allowed to fall freely into the ice storage box 13 below by rotating the ice tray 33 for collection. In this embodiment, the number of ice trays 33 is the same as the number of mounting frames 321, and each mounting frame 321 is provided with a corresponding water inlet 3215, that is, the mounting frame 321 and the water inlet pipe 312 are arranged in a one-to-one correspondence.

[0082] In one embodiment, as shown in Figure 9, an overflow cover 3216 is provided on the frame 32. The overflow cover 3216 is located around the water inlet 3215, corresponding to the outside of the water outlet. The overflow cover 3216 is used to guide the water flow from the water inlet pipe 312 into the ice tray 33. By setting the overflow cover 3216, all the water discharged from the water outlet is guided into the ice tray 33. At the same time, splashing water droplets are blocked by the overflow cover 3216, preventing water from splashing onto the frame 32, thereby preventing the frame 32 from freezing and causing the water inlet 3215 to become blocked, ensuring water injection efficiency and stability. In this embodiment, the water inlet 3215 of the frame 32 is roughly rectangular and is located at the top of the frame 32, so that the water flows from top to bottom into the ice tray 33, resulting in higher water injection efficiency.

[0083] As shown in Figure 10, the overflow cover 3216 is approximately U-shaped. It is positioned around the periphery of the water inlet 3215, with its opening facing the water inlet pipe 312 to ensure that the water discharged from the pipe 312 contacts the overflow cover 3216 and is guided into the ice tray 33 below. In this embodiment, the overflow cover 3216 includes a side plate 32161 and a connecting plate 32162. The side plates 32161 are arranged opposite each other on both sides of the water injection pipe 312. The connecting plate 32162 is arranged between the two side plates 32161. The connecting plate 32162 is located on the side of the water injection hole 3215 away from the water injection pipe 312. The connecting plate 32162 mainly contacts the water flow discharged from the water injection pipe 312. The connecting plate 32162 is used to guide the water flow into the ice tray 33. The side plates 32161 on both sides of the connecting plate 32162 are used to block the water splashing during the contact between the connecting plate 32162 and the water flow, so as to prevent water from splashing onto the frame 32.

[0084] Referring to Figures 14 and 15, the connecting plate 32162 includes a first guide portion 32165 and a second guide portion 32166. The first guide portion 32165 is a straight plate and is connected to the frame 32. The first guide portion 32165 extends obliquely from the frame 32 towards the water injection pipe 312 and gradually approaches the water injection hole 3215. The second guide portion 32166 is also a straight plate and is located on the side of the first guide portion 32165 away from the frame 32. The second guide portion 32166 extends obliquely from the first guide portion 32165 towards the water injection hole 3215 and is located above the outlet end of the water injection pipe 312. In this embodiment, the water injection pipe 312 is a straight pipe, and the angle between the central axis of the water injection pipe 312 and the first guide portion 32165 is greater than the angle between the central axis of the water injection pipe 312 and the second guide portion 32166. By setting a large angle between the first guide part 32165 and the water injection pipe 312, the impulse of the water flow is reduced as much as possible after the water flow comes into contact with the first guide part 32165, thereby improving the guiding effect of the first guide part 32165 on the water flow; by setting a small angle between the second guide part 32166 and the water injection pipe 312, the gap between the second guide part 32166 and the water injection pipe 312 is reduced, thereby improving the blocking effect on splashing water.

[0085] In some embodiments, the overflow cover 3216 can be integrated with the mounting bracket 321. By integrating the overflow cover 3216 and the mounting bracket 321, only the mounting bracket 321 needs to be fixed during installation, thereby improving assembly efficiency. Furthermore, integrating the overflow cover 3216 and the mounting bracket 321 prevents water leakage at the joint between them, thus preventing the mounting bracket 321 from freezing due to water seepage. In addition, integrating the overflow cover 3216 and the mounting bracket 321 effectively increases the load-bearing strength between them, improving the reliability of water flow guidance and splash prevention.

[0086] In some embodiments, as shown in FIG7, the water injection pipe 312 includes an inner pipe 3121 and an outer pipe 3122. The inner pipe 3121 is a hollow circular tube, and the water outlet is disposed on the inner pipe 3121 for injecting water into the ice tray 33. The outer pipe 3122 is a hollow circular tube, and the outer pipe 3122 is disposed around the outside of the inner pipe 3121. A gap is provided between the outer pipe 3122 and the inner pipe 3121 to reduce the thermal conductivity of the water injection pipe 312 and prevent the water from freezing and becoming blocked due to the low temperature environment during the flow of water in the inner pipe 3121.

[0087] In one embodiment, to clearly show the relationship between the water injection pipe 312 and the overflow cover 3216, Figures 16 and 17 conceal the end cap 311. As shown in Figures 16 and 17, the outlet end of the inner tube 3121 of the water injection pipe 312 faces the connecting plate 32162. The connecting plate 32162 reduces the force of the water flow at the outlet end and prevents water from splashing out.

[0088] In one embodiment, as shown in FIG7, the water injection pipe 312 further includes a heating element 3123. The heating element 3123 is annular and is disposed between the inner pipe 3121 and the outer pipe 3122. The heating element 3123 is used to heat the inner pipe 3121, thereby preventing the water from freezing in the inner pipe 3121 and ensuring the stability of water injection into the ice grid 33 from the inner pipe 3121. As shown in Figure 4, the outer tube 3122 is connected to the end cap 311, and the inner tube 3121 and the heating element 3123 pass through the end cap 311 and extend towards the water inlet 3215. By passing the inner tube 3121 through the end cap 311, water is injected into the ice grid 33 through the inner tube 3121. By passing the heating element 3123 through the end cap 311, the heating element 3123 is at least partially disposed between the end cap 311 and the frame 32. The heat generated by the heating element 3123 is then transferred to the overflow cover 3216, preventing the water from freezing at the overflow cover 3216 and improving the stability of water injection.

[0089] As shown in Figure 4, a positioning sleeve 3117 is provided on the end cap 311 to cooperate with the water injection pipe 312. The positioning sleeve 3117 is fixed to the end cap 311. The outer wall of the outer tube 3122 of the water injection pipe 312 can be provided with threads, and the inner wall of the positioning sleeve 3117 can also be provided with threads. The water outlet end of the water injection pipe 312 is inserted into the positioning sleeve 3117 and fixed by threaded connection. The positioning sleeve 3117 not only realizes the positioning of the water injection pipe 3117, but also realizes the connection and fixation between the water injection pipe 312 and the end cap 311. As shown in Figure 18, after the end cap 311 is connected and fixed to the inner liner 12, the end cap 311 closes the opening on the inner liner 12, and the water injection pipe 312 is inserted into the positioning sleeve 3117, realizing the connection between the water injection pipe 312 and the end cap 311.

[0090] In some embodiments, as shown in FIG4, a stop ring 31221 is also provided on the outer tube 3122 of the water injection pipe 312. The outer diameter of the stop ring 31221 is larger than the outer diameter of the positioning sleeve 3117. When the water injection pipe 312 is inserted into the positioning sleeve, the insertion length of the water injection pipe 312 is limited, and the length of the water injection pipe 312 inserted into the positioning sleeve 3117 is controlled to prevent the water injection pipe 312 from over-travel insertion.

[0091] In some embodiments, as shown in Figures 19 and 20, the ice tray 33 can be hinged to the interior of the mounting frame 321. In other embodiments, the ice tray 33 can also be connected to the mounting frame 321 via snap-fit ​​or connectors.

[0092] The ice tray 33 includes multiple ice trays 331 spaced apart. The shape of the ice trays 331 can be designed according to actual application or customer needs, such as rectangular, square, or oval shapes. The size of the ice trays 331 can also be designed according to actual application or customer needs, and is not further limited here. The control component 333, such as a motor or other drive component, can control the rotation of the rotating shaft 332 to pour the prepared ice cubes into the ice storage box 13.

[0093] In one embodiment, the ice tray 33 may further include an ice probe 334 for detecting whether the ice storage box 13 below is full of ice. If the ice storage box 13 is not full of ice, the control component 333 may control the rotating shaft 332 to rotate to remove ice.

[0094] Different sizes of ice trays can be selected for different types of refrigerators, and different sizes of ice trays can be used with the same end caps and mounting brackets. For different types of refrigerators, end caps and mounting brackets can be produced in a standardized manner, and then assembled according to the type. In this way, when producing different types of refrigerators, it is not necessary to create new molds to manufacture different end caps and mounting brackets, thereby reducing the number of mold openings for end caps and mounting brackets and reducing production costs.

[0095] This application also discloses a refrigerator 100, as shown in Figure 1, including a cabinet 10, a door 20, and an ice maker 30. The cabinet 10 includes a shell 11 and an inner liner 12, with the inner liner 12 disposed inside the shell 11, and a refrigeration chamber 15 disposed inside the inner liner 12. The door 20 is connected to the cabinet 10 to open or close the refrigeration chamber 15. The ice maker 30 is disposed inside the refrigeration chamber 15; the ice maker 30 includes a water injection unit 31, a frame 32, and an ice tray 33; the water injection unit 31 is connected to the inner liner 12, the frame 32 is mounted on the water injection unit 31, and the ice tray 33 is hinged inside the frame 32; the water injection unit 31 is used to inject water into the ice tray 33. The frame 32 includes a mounting bracket 321 and a locking block 322; the water injection unit 31 includes an end cap 311 and a water injection pipe 312; the number of end caps 311, water injection pipes 312, and ice trays 33 is the same as the number of mounting brackets 321, and each end cap 311, water injection pipe 312, mounting bracket 321, and ice tray 33 is set one-to-one. By setting the end caps 311, water injection pipes 312, mounting brackets 321, and ice trays 33 one-to-one, the entire ice maker 30 is modularized, that is, one end cap 311, one water injection pipe 312, one mounting bracket 321, and one ice tray 33 can form an ice-making module, and the number of ice-making modules can be adjusted by assembling them. By setting up multiple assembleable ice-making modules, different ice-making needs can be met, and later maintenance is convenient. The ice-making operation of each ice-making module will not affect each other. If one ice-making module is damaged, it will not affect the normal operation of other ice-making modules, ensuring the stability of ice-making operation.

[0096] In summary, the present application provides a refrigerator 100, which has the following advantages:

[0097] By setting multiple end caps 311, which are detachably connected and fixed, and the water injection pipes 312 are connected one-to-one with the end caps 311, the modular structure design of the water injection unit 31 is realized. When different numbers of water injection pipes 312 are needed, only the corresponding number of end caps 311 need to be assembled. This allows the end caps 311 of different specifications of water injection units 31 to be interchangeable. The factory can carry out unified mass production of the specifications and structure of the end caps 311, thereby reducing production costs.

[0098] By setting multiple mounting brackets 321, which are detachably fixed together by locking blocks 322, a modular structure design for the frame 32 is achieved. When different quantities and / or different specifications of ice trays 33 are required, the corresponding number of mounting brackets 321 can be assembled, allowing the mounting brackets 321 of different specifications to be interchangeable, reducing production costs. Furthermore, the modular structure of the frame 32 cooperates with the modular structure of the end cover 311, allowing for arbitrary adjustment of the combination and matching between the water injection pipe 312 and the ice tray 33 to meet the needs of different users and improve the adaptability of the ice maker 30.

[0099] The latching part 3222 engages with the latch along the first direction, and the pin part 3223 is inserted into the socket 3214 along the second direction. This multi-directional combination forms a fixing structure, enabling the locking block 322 to fix the mounting bracket 321 in multiple directions, thus improving the reliability of the fixation between two adjacent mounting brackets 321. By setting the positioning post 3212 and the positioning part 3224, the installation position of the locking block 322 is quickly positioned, improving the assembly efficiency between the mounting brackets 321. Furthermore, the structure of the positioning post 3212 passing through the positioning part 3224 further enhances the reliability of the fixation between two adjacent mounting brackets 321.

[0100] By providing a boss 3211 on the outer side wall of the bottom of the mounting bracket 321, when the locking block 322 is inserted between two adjacent mounting brackets 321, the pin 3223 is inserted into the socket 3214 on the boss 3211, so that the base 3221 abuts against the boss 3211. The weight of the locking block 322 itself helps to stably insert the pin 3223 into the socket 3214, improving the reliability of the connection between the locking block 322 and the mounting bracket 321. Furthermore, by providing the pin 3223 and the latch 3222 on both sides of the base 3221 respectively, during disassembly, pressing the spring 32221 separates the latch 32222 from the socket 3213, and then pulling the locking block 322 upwards is sufficient. During assembly, the locking block 322 is simply inserted downwards. The disassembly and assembly operations are simple, improving disassembly and assembly efficiency.

[0101] By setting an overflow cover 3216 around the water inlet 3215, the overflow cover 3216 covers the outside of the water outlet and guides the water flow, so as to guide the water flow into the ice grid 33 and block the splashing water, so as to prevent the water from splashing onto the frame 32 during the process of water being injected into the ice grid 33 from the water inlet pipe 312, thus eliminating the problem of ice formation on the frame 32 and ensuring water injection efficiency and stability.

[0102] The overflow cover 3216's connecting plate 32162 includes a first guide portion 32165 and a second guide portion 32166. The angle between the first guide portion 32165 and the water injection pipe 312 is greater than the angle between the second guide portion 32166 and the water injection pipe 312. The first guide portion 32165 guides the water flow at a larger angle to reduce the water flow momentum and ensure that the water flow is better guided into the ice tray 33. At the same time, by setting a smaller angle between the second guide portion 32166 and the water injection pipe 312, the gap between the overflow cover 3216 and the water injection pipe 312 is reduced, which can effectively block splashing water and thus improve the overflow cover 3216's effect of blocking splashing water.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
