[0003] In the related art, the driving mechanism is usually installed on the door or box of the refrigerator, and the driving mechanism has a rotatable output shaft. The end of the output shaft is fixedly connected with a first coupling, and the first coupling is provided with a connecting protrusion. The ice storage bucket is detachably connected to the door or box, and the ice storage bucket is provided with a receiving recess corresponding to the first coupling. The ice discharging mechanism includes a rotating shaft rotatably installed in the ice storage bucket, and a plurality of blades located in the ice storage bucket and sleeved on the rotating shaft. The rotating shaft is coaxially arranged with the output shaft, and one end of the rotating shaft toward the output shaft extends out of the receiving recess. The end of the rotating shaft extending out is sleeved with a second coupling movable along its axial direction, and the second coupling is accommodated in the receiving recess. A connecting recess is provided on the side of the second coupling facing away from the rotating shaft, which is used to be sleeved on the connecting protrusion. An elastic member is also provided in the receiving recess, and the elastic member applies a thrust toward the first coupling to the second coupling.

[0004] However, in the refrigerator of the related art, the ice storage space in the ice storage bucket is limited, which reduces the ice storage capacity of the ice storage bucket. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator, which can solve the technical problem that the ice storage space in the ice storage bucket of the refrigerator in the related art is limited, thereby reducing the ice storage capacity of the ice storage bucket.

[0006] An embodiment of the present application provides a refrigerator, comprising:

[0007] A box body having a refrigeration compartment;

[0008] A door body, which is rotatably connected to the box body and is used to open or close the refrigeration compartment;

[0009] An ice maker connected to the box or the door;

[0010] A driving mechanism, which is located below the ice maker and installed on the door body or the box body, and the driving mechanism includes a driving body and a rotatable output shaft connected to the driving body;

[0011] A first coupling, slidably connected to the output shaft along the axial direction;

[0012] an elastic member, located between the driving body and the first coupling, for applying a thrust force to the first coupling away from the driving body;

[0013] An ice storage bucket, which is located below the ice maker and is detachably connected to the door body or the box body, an ice outlet is provided below the ice storage bucket, and the ice storage bucket is provided with a receiving recess corresponding to the first coupling;

[0014] an ice dispensing mechanism, which is disposed in the ice storage bucket, the ice dispensing mechanism comprising a rotating shaft and a plurality of blades sleeved on the rotating shaft, the rotating shaft being coaxially disposed with the output shaft, the rotating shaft being rotatably connected with the ice storage bucket, and one end of the rotating shaft toward the output shaft protruding from the accommodating recess;

[0015] The second coupling is accommodated in the accommodating recess and fixedly connected to the rotating shaft; one of the first coupling and the second coupling is provided with a second connecting recess and the other is provided with a second connecting protrusion, and the second connecting protrusion is inserted in the second connecting recess.

[0016] The refrigerator of the embodiment of the present application is configured such that the first coupling is slidably connected to the output shaft of the driving mechanism, and the elastic member is disposed between the driving body of the driving mechanism and the first coupling so as to apply a thrust toward the second coupling to the first coupling; the second coupling is configured to be fixedly connected to the end of the rotating shaft extending out of the ice storage bucket. When the ice storage bucket is mounted on the door body or the box body, the elastic member pushes the first coupling to slide along the output shaft so that the first coupling and the second coupling are connected. The accommodating recessed portion provided in the ice storage bucket only needs to accommodate the second coupling, and does not need to accommodate the elastic member. Compared with the related art, the volume of the accommodating recessed portion can be reduced, thereby increasing the ice storage space in the ice storage bucket, and further increasing the ice storage amount in the ice storage bucket.

[0017] In some embodiments of the present application, a connecting column is provided on the side of the output shaft facing away from the driving body, and the outer side of the connecting column has at least one first connecting protrusion along its extension direction; the first coupling is provided with a first connecting through hole, and at least one first connecting recess is provided on the hole wall of the first connecting through hole, at least one first connecting recess is provided corresponding to at least one first connecting protrusion, and each first connecting recess is sleeved on the first connecting protrusion corresponding thereto.

[0018] In this way, the first coupling and the connecting column are slidably connected through the first connecting protrusion and the first connecting recess that are sleeved on each other, and the first connecting protrusion and the first connecting recess that are sleeved on each other can prevent relative rotation between the first coupling and the output shaft as much as possible, thereby improving the transmission efficiency between the output shaft and the first coupling.

[0019] In some embodiments of the present application, the refrigerator further includes a limiting member, which is connected to a side of the connecting column facing away from the driving body and is used to limit the first coupling.

[0020] Such an arrangement can prevent the first coupling from being separated from the connecting column when sliding on the connecting column as much as possible, thereby improving the reliability of the sliding connection between the first coupling and the connecting column.

[0021] In some embodiments of the present application, a first mounting groove is provided on the side of the connecting column facing away from the driving body, a second mounting groove is provided at the bottom of the first mounting groove, and a snap-in recess is provided on the groove wall of the second mounting groove; the limiting member includes a limiting plate and a connecting arm connected to each other, the limiting plate is accommodated in the first mounting groove, and the limiting plate is used to abut against the first coupling; the connecting arm is accommodated in the second mounting groove, and a snap-in protrusion is provided at one end of the connecting arm away from the limiting plate, and the snap-in protrusion is snap-into the snap-in recess.

[0022] With such an arrangement, when the limit member is installed on the connecting column, the connecting arm can be inserted into the second installation groove until the snap-fitting protrusion is snap-fitted into the snap-fitting recessed portion. At this time, the limit plate can be accommodated in the first installation groove, and there is no need to additionally set up connecting parts such as bolts, thereby improving the convenience of installing the limit member.

[0023] In some embodiments of the present application, a third mounting groove is provided on the side of the output shaft facing away from the driving body, and the connecting column is provided in the third mounting groove; a support column is provided in the third mounting groove, and the support column and the connecting column are spaced apart; the elastic member is a compression spring, one end of the compression spring is sleeved on the support column and abuts against the bottom of the third mounting groove, and the other end of the compression spring abuts against the first coupling.

[0024] With such an arrangement, the support column can support the compression spring to prevent the compression spring from being skewed during deformation as much as possible, thereby preventing the thrust applied by the compression elasticity to the first coupling from being deflected as much as possible.

[0025] In some embodiments of the present application, a receiving groove is provided on a side of the first coupling facing the compression spring, and the other end of the compression spring abuts against the bottom of the receiving groove.

[0026] In this way, the receiving groove can be used to accommodate part of the compression spring to reduce the size of the first coupling and the compression spring in the circumferential direction, which is conducive to the miniaturization of the ice-making device. In addition, the groove wall of the receiving groove can also block the compression spring to prevent the compression spring from being skewed as much as possible during the deformation process, thereby preventing the thrust applied by the compression elasticity to the first coupling from being deflected as much as possible.

[0027] In some embodiments of the present application, a mounting through hole is provided on the side of the accommodating recess opposite to the first coupling; a connecting tube is provided in the ice storage bucket, and the connecting tube cover is provided with the mounting through hole; the second coupling is accommodated in the connecting tube and can rotate in the connecting tube, and the second coupling is provided with a second connecting through hole, and the second connecting through hole is sleeved on the rotating shaft.

[0028] With this arrangement, the rotating shaft is rotationally connected to the side of the ice storage bucket facing the first coupling through the second coupling, and no additional rotating connecting member is required on the side of the rotating shaft and the ice storage bucket facing the first coupling, thereby simplifying the structure of the ice dispensing mechanism.

[0029] In some embodiments of the present application, the outer side of the rotating shaft is provided with at least one first plane arranged along its axial direction; the hole wall of the second connecting through hole is provided with at least one second plane, at least one second plane is arranged corresponding to at least one first plane, and when the second connecting through hole is sleeved on the rotating shaft, each second plane is in contact with the corresponding first plane.

[0030] With such an arrangement, when the rotating shaft rotates, the second plane can be pushed by the first plane, thereby driving the second coupling to rotate, and relative rotation between the second coupling and the rotating shaft can be prevented as much as possible, thereby improving the rotational synchronization between the second coupling and the rotating shaft.

[0031] In some embodiments of the present application, the ice storage bucket is provided with a third connecting through hole, and the third connecting through hole is located above the accommodating recessed portion; the refrigerator also includes an ice stirring tray and an ice stirring rod, and the ice stirring tray is rotatably installed at the third connecting through hole, and the ice stirring tray is provided with a first tooth structure on the circumferential side outside the ice storage bucket; the ice stirring rod is located in the ice storage bucket and is connected to the ice stirring tray; the circumferential side of the first coupling is provided with a second tooth structure, and the second tooth structure is transmission-connected to the first tooth structure.

[0032] With such a configuration, when the output shaft of the driving mechanism rotates, the output shaft drives the first coupling to rotate, and the first coupling can drive the ice-stirring plate and the ice-stirring rod to stir ice through the first toothed structure and the second toothed structure connected in transmission. The transmission chain includes the output shaft and the first coupling, and the first coupling and the ice-stirring plate and the ice-stirring rod, with a total of two stages of transmission. Compared with the above implementation, the length of the transmission chain is shortened, thereby reducing transmission losses and improving transmission efficiency. In addition, the power requirements for the driving mechanism are also reduced, thereby reducing the cost of the driving mechanism.

[0033] In some embodiments of the present application, the refrigerator further includes a transmission gear, which is rotatably mounted on the outer side of the ice storage bucket and meshes with the first toothed structure and the second toothed structure.

[0034] In this way, the first toothed structure and the second toothed structure are connected by transmission gears. By providing transmission gears, the radial dimensions of the first coupling and the ice-stirring tray can be reduced without changing the axis of the output shaft and the ice-stirring tray, which is conducive to miniaturization of the ice-making device.

[0079] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0082] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0083] The terms "first", "second" and the like are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined with "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0084] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0085] To meet the users' demand for ice, refrigerators in the related art are usually equipped with an ice maker for making ice, an ice storage bucket for storing ice cubes separated from the ice maker, an ice dispensing mechanism arranged in the ice storage bucket for dispensing ice, and a driving mechanism for driving the ice dispensing mechanism.

[0086] The drive mechanism is usually installed on the door or box of the refrigerator, and has a rotatable output shaft. Figure 1As shown, the end of the output shaft is fixedly connected with a first coupling 100', and the first coupling 100' is provided with a connecting protrusion 110'. The ice storage bucket 200' is detachably connected to the door body or the box body, and the ice storage bucket 200' is provided with a receiving recess 210' corresponding to the first coupling 100'. The ice dispensing mechanism 300' includes a rotating shaft 310' rotatably mounted in the ice storage bucket 200', and a plurality of blades 320' located in the ice storage bucket 200' and sleeved on the rotating shaft 310'. The rotating shaft 310' is coaxially arranged with the output shaft, and the rotating shaft 310' extends out from the receiving recess 210' toward one end of the output shaft. The extended end of the rotating shaft 310' is sleeved with a second coupling 400' movable along its axial direction, and the second coupling 400' is accommodated in the receiving recess 210'. A connecting recess 410' is provided on the side of the second coupling 400' facing away from the rotating shaft 310', which is used to be sleeved on the connecting protrusion 110'. An elastic member 500' is also provided in the accommodating recess 210', and the elastic member 500' applies a thrust to the second coupling 400' toward the first coupling 100'.

[0087] When the ice storage bucket 200' is installed on a door or a box, if the connecting recessed portion 410' and the connecting protruding portion 110' are not aligned, the elastic member 500' always applies a thrust toward the first coupling 100' to the second coupling 400', so that the portion of the second coupling 400' where the connecting recessed portion 410 is not provided can abut against the connecting protruding portion 110'. The driving mechanism drives the first coupling 100' to rotate, and the connecting protrusion 110' can rotate on the second coupling 400' first. When the connecting protrusion 110' rotates to be opposite to the connecting recess 410', the second coupling 400' moves toward the first coupling 100' under the thrust of the elastic member 500', so that the connecting recess 410' is sleeved on the connecting protrusion 110', so that the first coupling 100' can drive the second coupling 400' and the rotating shaft 310' to rotate, and the rotating shaft 310' drives the blade 320' to rotate to send the ice cubes in the ice storage bucket out.

[0088] However, the refrigerator in the related art has a technical problem that the ice storage space of the ice storage bucket is limited, which reduces the ice storage capacity of the ice storage bucket. The inventor has found that the reason is that the side of the ice storage bucket facing the driving member is usually used as a positioning surface for positioning with the door body or the box body. In order to ensure the relative position accuracy between the ice storage bucket and the door body or the box body, it is necessary to prevent the second coupling 400' from protruding from the side of the ice storage bucket facing the driving member as much as possible. Therefore, a accommodating recessed portion is provided on the side of the ice storage bucket, and the accommodating recessed portion is used to accommodate the second coupling 400' and the elastic member 500'. Due to the existence of the accommodating recessed portion, the ice storage space in the ice storage bucket is reduced, thereby reducing the ice storage capacity of the ice storage bucket.

[0089] In view of this, an embodiment of the present application provides a refrigerator, wherein a first coupling is set to be slidably connected to the output shaft of a driving mechanism, and an elastic member is set between the driving body of the driving mechanism and the first coupling to apply a thrust toward the second coupling to the first coupling; the second coupling is set to be fixedly connected to one end of the rotating shaft extending out of the ice storage bucket. When the ice storage bucket is installed on a door body or a box body, the elastic member pushes the first coupling to slide along the output shaft so that the first coupling and the second coupling are connected. The accommodating recessed portion provided in the ice storage bucket only needs to accommodate the second coupling, and there is no need to accommodate the elastic member. Compared with the related art, the volume of the accommodating recessed portion can be reduced, thereby increasing the ice storage space in the ice storage bucket, and thus increasing the ice storage amount in the ice storage bucket.

[0090] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0091] refer to Figure 2 The refrigerator of the embodiment of the present application may include a box body 100 and a door body 200. The box body 100 may be configured with a refrigeration compartment. The refrigeration compartment may be used to store food and other items. The door body 200 may be rotatably connected to the box body 100 to open or close the refrigeration compartment.

[0092] For example, there may be a plurality of door bodies 200. Each refrigeration compartment may be provided with a corresponding door body 200, or a plurality of refrigeration compartments may be provided with a corresponding door body 200. Figure 2 As shown, two door bodies 200 may be provided corresponding to one refrigeration compartment.

[0093] The box body 100 may include a box shell and a box liner. The box shell may be configured with a storage compartment having a first opening. The box shell may form the appearance of a refrigerator. The box liner may be placed in the storage compartment via the first opening, and the box liner may be configured with a refrigeration compartment having a second opening, and the second opening and the first opening may be located on the same side of the box shell. A user may place an item into the refrigeration compartment via the second opening, or take an item out of the refrigeration compartment.

[0094] The box body 100 may further include a first insulation layer. The first insulation layer may be filled between the box liner and the box shell to insulate the refrigeration compartment, reduce the heat exchange between the refrigeration compartment and the outside of the refrigerator, and thus reduce the energy consumption of the refrigerator. Exemplarily, in some possible implementations of the embodiments of the present application, the first insulation layer may be formed by foaming the insulation material and filling it between the box shell and the box liner.

[0095] Continue to refer Figure 3 and Figure 4 For example, the door body 200 may include a door liner 220 and a door shell 210 that are arranged opposite to each other. The door shell 210 may form the appearance of the refrigerator. The door liner 220 may be located on a side of the door shell 210 that faces the refrigeration compartment when the door body 200 is closed. The door shell 210 may be connected to the door liner 220.

[0096] The door body 200 may further include a second insulation layer, which may be filled between the door liner 220 and the door shell 210 to insulate the refrigeration compartment when the door body 200 is closed, thereby reducing heat exchange between the refrigeration compartment and the outside of the refrigerator, thereby reducing energy consumption of the refrigerator. For example, in some possible implementations of the present application, the second insulation layer may be formed by foaming the insulation material and filling it between the cabinet shell and the cabinet liner.

[0097] The refrigerator of the embodiment of the present application may also include a refrigeration system, which is used to provide coldness for the refrigeration compartment. Exemplarily, the refrigeration system may include a compressor, a condenser, a capillary tube and an evaporator that are cyclically connected. When the refrigeration system is running, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and transports the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid, and transports it to the capillary tube. After the capillary tube reduces the pressure of the refrigerant liquid, the high-pressure and low-temperature refrigerant liquid is converted into a low-pressure and low-temperature refrigerant liquid, and transported to the evaporator. After receiving the low-pressure and low-temperature refrigerant liquid, the evaporator boils it under isobaric conditions, absorbs heat and vaporizes it to form refrigerant vapor, so as to reduce the temperature in the refrigeration compartment.

[0098] The refrigerator of the embodiment of the present application may further include an ice-making device 300, which may have functions such as making ice, storing ice, or delivering ice to meet the ice needs of the user. In some possible implementations of the embodiment of the present application, the ice-making device 300 may be arranged in the box 100 to provide cold capacity for the ice-making device 300. In other possible implementations of the embodiment of the present application, the ice-making device 300 may be arranged in the door body 200 to minimize the space occupied by the ice-making device 300 in the refrigeration room for storing articles, which is conducive to increasing the article capacity of the refrigerator.

[0099] The following is an example of the ice-making device 300 being disposed on the door body 200 to describe the technical solution of the embodiment of the present application in detail. The implementation of the ice-making device 300 being disposed in the box body 100 can refer to the following description, which will not be repeated here.

[0100] refer to Figure 5The ice-making device 300 may include a mounting frame 310, and the mounting frame 310 may be connected to the side of the door liner 220 facing away from the door shell 210. Other components of the ice-making device 300 may be mounted on the mounting frame 310. During the process of making the second thermal insulation layer, when the thermal insulation material is foamed, the foamed thermal insulation material will apply an expansion force to the door liner 220, causing the door liner 220 to deform. By providing the mounting frame 310, the embodiment of the present application allows other components of the ice-making device 300 to be connected to the door liner 220 through the mounting frame 310. Compared with being directly connected to the door liner 220, the mounting frame 310 can provide a more accurate installation reference for other components of the ice-making device 300, thereby improving the position accuracy of each component in the ice-making device 300.

[0101] For example, Figure 5 As shown, the side of the door liner 220 facing away from the door housing 210 may be provided with a first mounting surface 221 and a second mounting surface 222 connected to each other, the first mounting surface 221 may extend vertically, and the second mounting surface 222 may extend horizontally. The mounting frame 310 may include a first mounting plate 311 and a second mounting plate 312 connected to each other, the first mounting plate 311 may be opposite to the first mounting surface 221 and connected to the first mounting surface 221. The second mounting plate 312 may be opposite to the second mounting surface 222 and connected to the second mounting surface 222. The first mounting surface 221 may position the first mounting plate 311 in the horizontal direction, and the second mounting surface 222 may position the second mounting plate 312 in the vertical direction, so that the door liner 220 and the mounting frame 310 may be positioned from multiple directions, thereby improving the relative position accuracy between the door liner 220 and the mounting frame 310, as well as the ice maker 320.

[0102] The ice making device 300 may further include an ice making machine 320, which is used to make ice. The ice making machine 320 may be connected to the box body 100 or the door body 200. Figure 5 As shown, the ice maker 320 can be connected to the mounting bracket 310 , and the mounting bracket 310 can be installed on the door liner 220 .

[0103] Exemplarily, the ice maker 320 may include an ice-making support 321, an ice tray 322, and an air supply member 323. The ice-making support 321 may be connected to the mounting frame 310. The ice tray 322 is connected to the ice-making support 321 and is used to hold water. The air supply member 323 may be connected to the mounting frame 310 and located above the ice-making support 321. The air supply member 323 is used to blow the cold generated by the refrigeration system to the top of the ice tray 322 so that the water in the ice tray 322 is frozen into ice cubes.

[0104] In some possible implementations of the present application, the ice tray 322 may be rotatably connected to the ice making support 321 around a horizontal axis. The ice maker 320 may further include an ice turning motor 324, which may be connected to the ice tray 322 to drive the ice tray 322 to turn over, so that the ice cubes in the ice tray 322 are detached, and no manual deicing operation is required, thereby improving the convenience of using the ice making device 300.

[0105] The ice-making device 300 may further include a driving mechanism 340, which may be located below the ice-making machine 320 and mounted on the door body 200 or the box body 100. Figure 6 and Figure 7 As shown, the driving mechanism 340 may include a driving body 341 and an output shaft 342 connected to the driving body 341 and rotatable.

[0106] The ice making device 300 may further include a first coupling 350, and the first coupling 350 may be axially slidably connected to the output shaft 342. Figure 6 , Figure 7 and Figure 8 As shown, a connecting column 343 may be provided on the side of the output shaft 342 facing away from the driving body 341, and the outer side of the connecting column 343 may have at least one first connecting protrusion 344 along its extension direction. The first coupling 350 may be provided with a first connecting through hole 351, and at least one first connecting recess 352 may be provided on the hole wall of the first connecting through hole 351, and at least one first connecting recess 352 is provided corresponding to at least one second connecting protrusion 381, and each first connecting recess 352 may be sleeved on the first connecting protrusion 344 corresponding thereto. The first coupling 350 and the connecting column 343 are slidably connected through the mutually sleeved first connecting protrusion 344 and the first connecting recess 352, and the mutually sleeved first connecting protrusion 344 and the first connecting recess 352 can prevent relative rotation between the first coupling 350 and the output shaft 342 as much as possible, thereby improving the transmission efficiency between the output shaft 342 and the first coupling 350.

[0107] In some possible implementations of the embodiment of the present application, the number of the first connection protrusion 344 and the number of the first connection recess 352 may both be one.

[0108] In some other possible implementations of the embodiment of the present application, the number of the first connection protrusions 344 and the number of the first connection recesses 352 can be multiple, for example Figures 6 to 8As shown, the number of the first connection protrusions 344 and the number of the first connection recesses 352 can both be four. Multiple first connection protrusions 344 can be evenly arranged in the circumferential direction of the connection shaft, and multiple first connection recesses 352 can be evenly arranged on the circumferential hole wall of the first connection through hole 351. Each first connection protrusion 344 is inserted into the first connection recess 352 corresponding thereto, so that the output shaft 342 and the first coupling 350 can be connected through multiple first connection protrusions and multiple first connection recesses 352 evenly arranged in the circumferential direction, thereby improving the uniformity of the connection strength between the output shaft 342 and the first coupling 350, which is conducive to improving the transmission stability.

[0109] like Figure 6 As shown, the refrigerator of the embodiment of the present application may also include a limit member 353, which can be connected to the side of the connecting column 343 facing away from the driving body 341, and is used to limit the first coupling 350 to prevent the first coupling 350 from detaching from the connecting column 343 when sliding on the connecting column 343 as much as possible, thereby improving the reliability of the sliding connection between the first coupling 350 and the connecting column 343.

[0110] For example, Figure 7 As shown, the side of the connecting column 343 facing away from the driving body 341 may be provided with a first mounting groove 345, the groove bottom of the first mounting groove 345 may be provided with a second mounting groove 346, and the groove wall of the second mounting groove 346 may be provided with a clamping recess 347. The limiting member 353 may include a connecting plate 354 and a connecting arm 355 connected to each other, the limiting plate 354 may be accommodated in the first mounting groove 345, and the limiting plate 354 is used to abut against the first coupling 350 to limit the first coupling 350. The connecting arm 355 may be accommodated in the second mounting groove 346, and one end of the connecting arm 355 away from the limiting plate 354 may be provided with a clamping protrusion 356, and the clamping protrusion 356 is clamped in the clamping recess 347 so that the connecting arm 355 is connected to the groove wall of the second mounting groove 346. When the limit member 353 is installed on the connecting column 343, the connecting arm 355 can be inserted into the second installation groove 346 until the snap-fit ​​protrusion 356 is snap-fitted into the snap-fit ​​recess 347. At this time, the limit plate 354 can be accommodated in the first installation groove 345, and there is no need to additionally set up bolts and other connecting parts, thereby improving the convenience of installing the limit member 353.

[0111] The ice making device 300 may further include an elastic member 360, which may be located between the driving body 341 and the first coupling 350, and is used to apply a thrust away from the driving body 341 to the first coupling 350. Exemplarily, the elastic member 360 may be a compression spring or a tension spring. The technical solution of the embodiment of the present application is described below by taking the elastic member 360 as a compression spring as an example. The specific implementation method when the elastic member 360 is a tension spring can be referred to the following content, which will not be repeated here.

[0112] For example, reference Figure 7 A third mounting groove 348 may be provided on the side of the output shaft 342 facing away from the driving body 341, and the connecting column 343 may be provided in the third mounting groove 348. A supporting column 349 may also be provided in the third mounting groove 348, and the supporting column 349 is spaced apart from the connecting column 343. One end of the compression spring may be sleeved on the supporting column 349 and abut against the bottom of the third mounting groove 348, and the other end of the compression spring may abut against the first coupling 350. The supporting column 349 may support the compression spring to prevent the compression spring from being skewed as much as possible during the deformation process, thereby preventing the thrust applied by the compression elasticity to the first coupling 350 from being deflected as much as possible.

[0113] refer to Fig. 9 , a receiving groove 357 may be provided on one side of the first coupling 350 facing the compression spring, and the other end of the compression spring may abut against the bottom of the receiving groove 357. The receiving groove 357 may be used to accommodate part of the compression spring, so as to reduce the size of the first coupling 350 and the compression spring in the circumferential direction, which is conducive to the miniaturization of the ice-making device 300. In addition, the groove wall of the receiving groove 357 may also block the compression spring, so as to prevent the compression spring from being skewed as much as possible during the deformation process, thereby preventing the thrust applied by the compression elasticity to the first coupling 350 from being deflected as much as possible.

[0114] refer to Fig.10 The ice making device 300 may further include an ice storage bucket 330, which may be located below the ice maker 320 and used to receive ice cubes separated from the ice maker 320. The ice storage bucket 330 may be detachably connected to the door body 200 or the box body 100, for example, the ice storage bucket 330 may be detachably connected to the mounting frame 310, so that the ice storage bucket 330 may be detached from the door body 200 or the box body 100, so as to facilitate cleaning or maintenance of the ice storage bucket 330. An ice outlet 331 may be provided below the ice storage bucket 330, and the ice outlet 331 is used to discharge ice. The ice storage bucket 330 may also be provided with a receiving recess 332 corresponding to the first coupling 350.

[0115] refer to Fig.11The ice making device 300 may further include an ice discharging mechanism 370, which may be disposed in the ice storage bucket 330. The ice discharging mechanism 370 may deliver the ice in the ice storage bucket 330 through the ice outlet 331. Exemplarily, the ice discharging mechanism 370 may include a rotating shaft 371, and a plurality of blades 372 sleeved on the rotating shaft 371. The rotating shaft 371 may be coaxially disposed with the output shaft 342. The rotating shaft 371 may be rotatably connected to the ice storage bucket 330. One end of the rotating shaft 371 facing the output shaft 342 may extend from the accommodating recess 332 to be connected to the output shaft 342. When the driving body 341 drives the output shaft 342 to rotate, the output shaft 342 may drive the rotating shaft 371 to rotate, and the rotating shaft 371 drives the plurality of blades 372 to rotate, and the plurality of blades 372 push the ice cubes in the ice storage bucket 330, so that the ice cubes are delivered from the ice outlet 331.

[0116] For example, the ice making device 300 of the embodiment of the present application may further include a second coupling 380, which may be accommodated in the accommodating recess 332 and fixedly connected to the rotating shaft 371. The second coupling 380 may be detachably connected to the first coupling 350. When the ice storage bucket 330 is mounted on the door body 200, the second coupling 380 is connected to the first coupling 350, and the rotary driving force provided by the output shaft 342 may be transmitted to the rotating shaft 371 through the first coupling 350 and the second coupling 380 to perform an ice dispensing operation.

[0117] For example, in the first coupling 350 and the second coupling 380, one of them may be provided with a second connection recess 358, and the other may be provided with a second connection protrusion 381. Figure 8 As shown, the second connection recess 358 can be provided on the first coupling 350. Fig.12 As shown, the second connection protrusion 381 can be provided on the second coupling 380. The second connection protrusion 381 can be inserted into the second connection recess 358. The first coupling 350 and the second coupling 380 can be connected by the second connection protrusion 381 and the second connection recess 358 that are inserted into each other.

[0118] When the ice storage bucket 330 is installed on the mounting frame 310, if the second connecting recess 358 and the second connecting protrusion 381 are not aligned, since the elastic member 360 always applies a thrust toward the second coupling 380 to the first coupling 350, the portion of the first coupling 350 where the second connecting recess 358 is not provided can be in contact with the second connecting protrusion 381. When the output shaft 342 of the driving mechanism 340 rotates, the first coupling 350 is driven to rotate. When the second connecting recess 358 of the first coupling 350 is opposite to the second connecting recess 358, the second connecting recess 358 can be sleeved on the second connecting protrusion under the action of the elastic member 360, so that the first coupling 350 is connected to the second coupling 380, so that the first coupling 350 can drive the second coupling 380 and the rotating shaft 371 to rotate, and the rotating shaft 371 drives the blade 372 to rotate to send the ice cubes in the ice storage bucket 330 out.

[0119] In the embodiment of the present application, the first coupling 350 is set to be slidably connected to the output shaft 342 of the driving mechanism 340, and the elastic member 360 is set between the driving body 341 of the driving mechanism 340 and the first coupling 350, so as to apply a thrust toward the second coupling 380 to the first coupling 350; the second coupling 380 is set to be fixedly connected to the end of the rotating shaft 371 extending out of the ice storage bucket 330. When the ice storage bucket 330 is installed on the door body 200 or the box body 100, the elastic member 360 pushes the first coupling 350 to slide along the output shaft 342, so that the first coupling 350 and the second coupling 380 are connected. The accommodating recessed portion 332 provided in the ice storage bucket 330 only needs to accommodate the second coupling 380, and does not need to accommodate the elastic member 360. Compared with the related art, the volume of the accommodating recessed portion 332 can be reduced, thereby increasing the ice storage space in the ice storage bucket 330 and further increasing the ice storage amount in the ice storage bucket 330 .

[0120] refer to Fig.13 and Fig.14 , a mounting through hole 333 may be provided on the side of the accommodating recess 332 opposite to the first coupling 350. A connecting cylinder 334 may be provided in the ice storage bucket 330, and the connecting cylinder 334 covers the mounting through hole 333. The second coupling 380 is accommodated in the connecting cylinder 334 and can rotate in the connecting cylinder 334. The second coupling 380 may be provided with a second connecting through hole 382, ​​and the second connecting through hole 382 may be sleeved on the rotating shaft 371. The rotating shaft 371 is rotatably connected to the side of the ice storage bucket 330 facing the first coupling 350 through the second coupling 380, and there is no need to provide an additional rotating connecting member on the rotating shaft 371 and the side of the ice storage bucket 330 facing the first coupling 350, thereby simplifying the structure of the ice dispensing mechanism 370.

[0121] refer to Fig.11 and Fig.12 , at least one first plane 373 arranged along the axial direction may be provided on the outer side of the rotating shaft 371. The hole wall of the second connecting through hole 382 may be provided with at least one second plane 383, and at least one second plane 383 is arranged corresponding to at least one first plane 373. When the second connecting through hole 382 is sleeved on the rotating shaft 371, each second plane 383 may fit with the first plane 373 corresponding thereto. When the rotating shaft 371 rotates, the second plane 383 may be pushed by the first plane 373, thereby driving the second coupling 380 to rotate, and relative rotation between the second coupling 380 and the rotating shaft 371 can be prevented as much as possible, thereby improving the rotation synchronization between the second coupling 380 and the rotating shaft 371.

[0122] For example, there may be two first planes 373, and the two first planes 373 may be symmetrically arranged relative to the axis of the rotating shaft 371. There may be two second planes 383, and the two second planes 383 may be symmetrically arranged relative to the axis of the second coupling 380, and the two second planes 383 are respectively fitted with the two first planes 373. It is understandable that the first planes 373 and the second planes 383 may also be other numbers, and the embodiments of the present application will not be repeated in detail.

[0123] like Fig.11 As shown, the ice storage bucket 330 may be provided with a third connection through hole 335, and the third connection through hole 335 may be located above the accommodating recessed portion 332. The ice making device 300 may further include an ice stirring tray 336 and an ice stirring rod 337, the ice stirring tray 336 may be rotatably mounted at the third connection through hole 335, and the circumferential side of the ice stirring tray 336 located outside the ice storage bucket 330 may be provided with a first toothed structure 338. The ice stirring rod 337 may be located in the ice storage bucket 330 and connected to the ice stirring tray 336.

[0124] In some possible implementations of the present application, the ice making device 300 may be provided with a connecting gear, which is sleeved on the rotating shaft 371, and the connecting gear is meshed with the second tooth structure 359 of the ice stirring tray 336. When the output shaft 342 of the driving mechanism 340 rotates, the output shaft 342 drives the first coupling 350 to rotate, the first coupling 350 drives the second coupling 380 to rotate, the second coupling 380 drives the rotating shaft 371 to rotate, the rotating shaft 371 drives the connecting gear to rotate, and the connecting gear drives the ice stirring tray 336 and the ice stirring rod 337 to stir ice, so as to prevent the ice cubes in the ice storage bucket 330 from sticking to each other. The transmission chain includes the output shaft 342 and the first coupling 350, the first coupling 350 and the second coupling 380, the second coupling 380 and the rotating shaft 371, the rotating shaft 371 and the connecting gear, and the connecting gear and the ice stirring tray 336 and the ice stirring rod 337, with a total of five levels of transmission.

[0125] In some other possible implementations of the embodiment of the present application, the circumferential side of the first coupling 350 may be provided with a second toothed structure 359, and the second toothed structure 359 may be transmission-connected to the first toothed structure 338. When the output shaft 342 of the driving mechanism 340 rotates, the output shaft 342 drives the first coupling 350 to rotate, and the first coupling 350 can drive the ice-stirring tray 336 and the ice-stirring rod 337 to stir ice through the first toothed structure 338 and the second toothed structure 359 that are transmission-connected. The transmission chain includes the output shaft 342 and the first coupling 350, and the first coupling 350 and the ice-stirring tray 336 and the ice-stirring rod 337, with a total of two stages of transmission. Compared with the above implementation, the length of the transmission chain is shortened, thereby reducing the transmission loss and improving the transmission efficiency. In addition, the power requirement for the driving mechanism 340 is also reduced, thereby reducing the cost of the driving mechanism 340.

[0126] In some possible implementations of the embodiments of the present application, the first toothed structure 338 and the second toothed structure 359 are transmission-connected, and the first toothed structure 338 and the second toothed structure 359 are meshed.

[0127] In some other possible implementations of the present application, Fig.11 As shown, the ice making device 300 may further include a transmission gear 339, which is rotatably mounted on the outer side of the ice storage bucket 330, and the transmission gear 339 may mesh with the first toothed structure 338 and the second toothed structure 359. The first toothed structure 338 and the second toothed structure 359 are connected in transmission via the transmission gear 339. By providing the transmission gear 339, the radial dimensions of the first coupling 350 and the ice stirring tray 336 may be reduced without changing the axis of the output shaft 342 and the ice stirring tray 336, which is beneficial to the miniaturization of the ice making device 300.

[0128] The ice maker 320 may further include an ice making housing 390, which may be disposed on a side of the ice maker 320 and the ice storage bucket 330 that faces away from the mounting frame 310 and is connected to the door liner 220. The ice making housing 390 may shield the ice maker 320 and the ice storage bucket 330, thereby improving the aesthetics of the door body 200, and may also protect the ice maker 320 and the ice storage bucket 330, thereby extending the service life of the ice maker 320 and the ice storage bucket 330.
