The embodiment of the application provides an ice maker 20 and a refrigerator, so as to solve the problem that the manufacturing difficulty of a transmission shaft 240 in an existing ice maker is high. The following description will be made with reference to the accompanying drawings.

Referring to fig. 1 to fig. 3, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, fig. 2 is a schematic structural diagram of a door body and an ice maker in the refrigerator shown in fig. 1, and fig. 3 is a schematic structural diagram of a part of an explosion structure of the door body and the ice maker shown in fig. 2. The ice maker 20 provided by the embodiment of the present application can be applied to a refrigerator. The refrigerator can be a double-door refrigerator, certainly, the refrigerator can also be a single-door refrigerator or a triple-door refrigerator, and the embodiment of the application takes the refrigerator as the double-door refrigerator for example. The refrigerator may include a door 10, an ice maker 20, and an ice-taking device 30. The ice maker 20 may be disposed in the refrigerator, and in particular, the ice maker 20 may be disposed inside the door 10. The ice-picking device 30 may also be disposed on the door 10, and specifically, the ice-picking device 30 may be disposed outside the door 10. The ice maker 20 makes ice in the refrigerator, the ice taking device 30 is connected with the ice maker 20 through the door 10 of the refrigerator to take ice cubes made from the ice maker 20, the door 10 of the refrigerator can be used as a connecting body of the ice maker 20 and the ice taking device 30, and the door 10, the ice maker 20 and the ice taking device 30 are matched in structure to achieve the purpose that the made ice cubes are taken out under the condition that the refrigerator is not opened.

It can be understood that, in the related art, the ice maker 20 of the refrigerator is disposed in a storage compartment such as a refrigerating compartment or a freezing compartment of the refrigerator, and occupies a space of the storage compartment. As shown in fig. 2, in the refrigerator provided in the embodiment of the present application, the ice maker 20 is installed inside the door 10 of the refrigerator, so that the space of the storage compartment is increased.

Referring to fig. 4-6, fig. 4 is a schematic view illustrating an assembly structure of an ice bank, a transmission shaft and a first linkage block in the ice maker shown in fig. 2, fig. 5 is a partially enlarged view of a portion P of an assembly of the ice bank, the transmission shaft and the first linkage block in the ice maker shown in fig. 4, and fig. 6 is an assembly view of an ice crushing motor, a transmission shaft, an ice crushing assembly and an ice pushing assembly in the ice maker shown in fig. 2. As shown in fig. 3, the ice maker 20 may include an ice making assembly 210, and the ice making assembly 210 is disposed on the door 10. Below the ice-making assembly 210, an ice bank bracket 220 is further provided on the door 10. The ice bank 230 is detachably mounted on the ice bank stand 220 and located below the ice-making assembly 210, and can receive and store ice cubes made by the ice-making assembly 210 and discharged downward. As shown in fig. 4, a driving shaft 240 is rotatably provided through a sidewall of the ice bank 230. One end of the transmission shaft 240 penetrating through the ice bank 230 is in transmission with an ice crushing motor 250 disposed on the ice bank bracket 220, and the transmission shaft 240 can be driven to rotate by the ice crushing motor 250. As shown in fig. 5, an ice crushing assembly 260 and an ice pushing member 270 are sleeved on one end of the driving shaft 240 extending into the ice bank 230. Wherein, the ice-crushing assembly 260 can selectively crush the ice cubes in the ice bank 230 by being in power connection with the transmission shaft 240. Wherein, the ice pushing part 270 is in power connection with the transmission shaft 240 and can push the ice cubes in the ice bank 230 to the ice crushing assembly 260.

As shown in fig. 3, the ice making assembly 210 may be directly or indirectly disposed on the door 10, for example, the ice making assembly 210 is directly fixed on the door 10 by screwing or clipping, or the ice making assembly bracket 110 is fixedly disposed on the door 10 as shown in this embodiment, and the ice making assembly 210 is fixedly disposed on the ice making assembly bracket 110. Wherein the ice making assembly 210 is capable of discharging ice downwardly, i.e., discharging the ice cubes made therein downwardly.

It is understood that, in the related art, the ice pushing member 270 is integrally formed with the driving shaft 240. For example, the ice pushing member 270 has a spiral structure formed on the sidewall of the driving shaft 240 such that the ice pushing member 270 and the driving shaft 240 form a structure of a feed screw, and the ice cubes are advanced by the spiral structure when the driving shaft 240 rotates. However, this structure causes high difficulty in molding and manufacturing the propeller shaft 240, and requires replacement of both parts when one of the screw structure or the propeller shaft 240 is damaged, thereby having a disadvantage of high maintenance cost. In order to solve the above problem, as shown in fig. 6, the ice maker 20 according to the embodiment of the present invention is designed to have a split structure of the ice pushing component 270 and the transmission shaft 240, so that the manufacturing difficulty and the manufacturing cost of the transmission shaft 240 are reduced, and the maintenance cost in the later period is also reduced.

Specifically, referring to fig. 7 and 8, fig. 7 is a schematic structural diagram of a transmission shaft in the ice maker shown in fig. 2, and fig. 8 is a schematic structural diagram of a first limiting component in the ice maker shown in fig. 2. In the embodiment of the present application, as shown in fig. 7, the transmission shaft 240 may include a position-limiting section 241, a first mounting section 242, and a second mounting section 243. The limiting section 241 can be used as a limiting reference to limit the position of the part mounted on the transmission shaft 240, and improve the position accuracy of each part during mounting. The first mounting section 242 is located at one side of the limiting section 241 far away from the ice crushing motor 250, and the ice pushing component 270 is sleeved on the first mounting section 242 in a detachable structure. The second mounting section 243 is located at one side of the limiting section 241 close to the ice crushing motor 250, the second mounting section 243 is rotatably mounted on the side wall of the ice storage box 230, the ice crushing assembly 260 is mounted on the portion, located in the ice storage box 230, of the second mounting section 243, and the portion, penetrating out of the ice storage box 230, of the second mounting section 243 is in transmission connection with the ice crushing motor 250.

It is understood that, in the related art, the ice-crushing motor 250 is mounted on the ice bank 230 on the one hand, and the ice-crushing motor 250 needs to be electrically connected to an electric circuit inside the refrigerator on the other hand. Therefore, when the user needs to clean the ice in the ice bank 230, the user needs to take down the ice bank 230, the distance for taking out the ice bank 230 is limited because the power line of the ice crushing motor 250 is plugged into the internal circuit of the refrigerator, and the operation is complicated if the power line is detached, thereby reducing the experience effect of the user.

Referring to fig. 9, fig. 9 is a schematic structural view of an ice bank bracket in the ice maker shown in fig. 2. In the embodiment of the present application, as shown in fig. 2, the ice crushing motor 250 is provided on the ice bank stand 220. Specifically, as shown in fig. 9, a plurality of positioning grooves 251 are formed in a housing of the ice crushing motor 250, and the plurality of positioning grooves 251 correspond to the plurality of motor positioning bosses 221 of the ice bank bracket 220 one to one, so that the ice crushing motor 250 can be quickly and accurately positioned on the ice bank bracket 220. After the ice crushing motor 250 is positioned on the ice bank bracket 220, the ice crushing motor 250 is further fixedly connected with the ice bank bracket 220 in a screw connection manner. Wherein, a hole for the power line of the ice crushing motor 250 to pass through is formed on the ice bank bracket 220, so that the power line of the ice crushing motor 250 can pass through the ice bank bracket 220 and then be connected to the circuit pre-embedded inside the door body 10 to form electrical connection, thereby solving the problem that the ice bank 230 is not convenient to detach when the ice crushing motor 250 is provided with the ice bank 230 in the related art.

An output shaft of the ice crushing motor 250 is selectively drivingly connected to an end of the driving shaft 240 extending out of the ice bank 230. In other embodiments, the matching structure of the ice crushing motor 250 and the transmission shaft 240 may be: a non-circular hole is formed on an end surface of the transmission shaft 240 facing the output shaft of the ice crushing motor 250, and an end portion of the output shaft of the ice crushing motor 250 is processed into the same shape as the non-circular hole, so that when the ice bank 230 is mounted to the ice bank stand 220, the output shaft of the ice crushing motor 250 is inserted into the transmission shaft 240 to form a power connection. In other embodiments, the output shaft of the ice crushing motor 250 may be semi-cylindrical, and the end of the transmission shaft 240 that is engaged with the ice crushing motor 250 is also semi-cylindrical, so that when the output shaft of the ice crushing motor 250 is abutted against the transmission shaft 240, a cylindrical structure is formed, and finally, the output shaft of the ice crushing motor 250 drives the transmission shaft 240 to rotate.

In the embodiment of the present application, please refer to fig. 10, and fig. 10 is a schematic view illustrating a first transmission structure of an ice crushing motor and a transmission shaft of the ice making machine shown in fig. 2. The matching structure of the ice crushing motor 250 and the transmission shaft 240 is as follows: the output shaft of the ice crushing motor 250 is provided with a second linkage block 252, and the end of the transmission shaft 240 extending out of the ice bank 230 is provided with a first linkage block 244. When the ice bank 230 is mounted to the ice bank stand 220, the first linkage 244 engages with the second linkage 252 to achieve a power connection of the ice crushing motor 250 with the driving shaft 240.

In an embodiment of the present application, as shown in fig. 5, the first link block 244 may include a first section 2441, a third section 2442, and a fifth section 2443, the first section 2441, the third section 2442, and the fifth section 2443 are sequentially connected, and the first section 2441 and the fifth section 2443 are each bent toward the ice bank stand 220 with respect to the third section 2442 to form a first groove 2444 between the first section 2441, the third section 2442, and the fifth section 2443. The second linkage block 252 may include a second segment 2521, a fourth segment 2522, and a sixth segment 2523, the second segment 2521, the fourth segment 2522, and the sixth segment 2523 are sequentially connected, and each of the second segment 2521 and the sixth segment 2523 is bent toward the ice bank 230 with respect to the fourth segment 2522, such that a second groove 2524 is formed between the second segment 2521, the fourth segment 2522, and the sixth segment 2523. When the ice bank 230 is mounted to the ice bank stand 220, the first linkage 244 is snapped into the second recess 2524 to engage with the second linkage 252, and the ice crushing motor 250 can drive the driving shaft 240 to rotate synchronously.

It can be understood that, during the installation of the ice bank 230, it will be required to previously adjust the angle of the first linkage block 244 on the driving shaft 240 in the circumferential direction so that the first linkage block 244 can be just snapped into the second recess 2524 of the second linkage block 252 during the installation. Therefore, the installation process of the ice bank 230 is troublesome.

In order to make the installation of the ice bank 230 easier, at least one of the first and second linkage blocks 244 and 252 is configured to be slidable in the axial direction of the driving shaft 240, and the first and second linkage blocks 244 and 252 are configured to be movable toward each other by providing an elastic member to form a snap-fit after being gathered.

As shown in fig. 10, as a first transmission structure of the ice crushing motor 250 and the transmission shaft 240: the first linkage block 244 is slidably mounted on the driving shaft 240, and the second linkage block 252 is fixedly disposed on an output shaft of the ice crushing motor 250. The elastic member includes a first elastic member 245, the first elastic member 245 may be a spring such as a disc spring or a compression spring fitted over the transmission shaft 240, and the first elastic member 245 is pre-pressed between the first link block 244 and the outer surface of the ice bank 230.

When the ice bank 230 is fitted to the ice bank stand 220, there are two cases:

1. the first segment 2441 and the fifth segment 2443 just fall within the second recess 2524. In this case, the first linkage block 244 and the second linkage block 252 directly engage.

2. The first segment 2441 and the fifth segment 2443 do not fall within the second groove 2524. In this case, the second linkage block 252 pushes the first linkage block 244 to approach the ice bank 230, so that the first elastic member 245 is in a compressed state, the first segment 2441 abuts against the second segment 2521, and the fifth segment 2443 abuts against the sixth segment 2523. When the ice bank 230 is installed in place, the ice crushing motor 250 rotates the second linkage block 252 to drop the first segment 2441 and the fifth segment 2443 into the second recess 2524, and the first elastic member 245 in a compressed state pushes the first linkage block 244 to approach the ice crushing motor 250, so that the second linkage block 252 is engaged with the first linkage block 244.

Referring to fig. 11, fig. 11 is a schematic view illustrating a second transmission structure of an ice crushing motor and a transmission shaft of the ice maker shown in fig. 2. As a second transmission structure of the ice crushing motor 250 and the transmission shaft 240: the second linkage block 252 is slidably mounted on the output shaft of the ice crushing motor 250, and the first linkage block 244 is fixedly disposed on the transmission shaft 240. The elastic member includes a second elastic member 253, the second elastic member 253 may be a spring such as a disc spring or a compression spring, which is sleeved on the output shaft of the ice crushing motor 250, and the second elastic member 253 is pre-pressed between the second linkage block 252 and the outer surface of the ice crushing motor 250.

When the ice bank 230 is fitted to the ice bank stand 220, there are two cases:

2. The first segment 2441 and the fifth segment 2443 do not fall within the second groove 2524. In this case, the first linkage block 244 pushes the second linkage block 252 close to the ice crushing motor 250, so that the second elastic member 253 is in a compressed state, the first segment 2441 abuts against the second segment 2521, and the fifth segment 2443 abuts against the sixth segment 2523. When the ice bank 230 is installed in place, the ice crushing motor 250 rotates the second linkage block 252 to drop the first segment 2441 and the fifth segment 2443 into the second recess 2524, and the second elastic member 253 in a compressed state pushes the second linkage block 252 away from the ice crushing motor 250 to engage the second linkage block 252 with the first linkage block 244.

Referring to fig. 12, fig. 12 is a schematic view illustrating a third transmission structure of an ice crushing motor and a transmission shaft of the ice maker shown in fig. 2. As a second transmission structure of the ice crushing motor 250 and the transmission shaft 240: the second linkage block 252 is slidably mounted on the drive shaft 240, and the first linkage block 244 is slidably mounted on the output shaft of the ice crushing motor 250. The elastic member includes a first elastic member 245 and a second elastic member 253. The first elastic member 245 may be a spring such as a disc spring or a compression spring fitted around the transmission shaft 240, and the first elastic member 245 is pre-pressed between the first linkage block 244 and the outer surface of the ice bank 230, the second elastic member 253 may be a spring such as a disc spring or a compression spring fitted around the output shaft of the ice-crushing motor 250, and the second elastic member 253 is pre-pressed between the second linkage block 252 and the outer surface of the ice-crushing motor 250.

When the ice bank 230 is fitted to the ice bank stand 220, there are two cases:

2. The first segment 2441 and the fifth segment 2443 do not fall within the second groove 2524. In this case, the first linkage 244 and the second linkage 252 are pushed against each other such that the first linkage 244 is adjacent to the ice bank 230 and the second linkage 252 is adjacent to the ice crushing motor 250, so that the first elastic member 245 and the second elastic member 253 are compressed, the first segment 2441 abuts against the second segment 2521, and the fifth segment 2443 abuts against the sixth segment 2523. When the ice bank 230 is mounted in place, the ice crushing motor 250 rotates the second linkage block 252 to allow the first segment 2441 and the fifth segment 2443 to fall into the second recess 2524, the first elastic member 245 in a compressed state pushes the first linkage block 244 away from the ice bank 230, and the second elastic member 253 in a compressed state pushes the second linkage block 252 away from the ice crushing motor 250 to allow the second linkage block 252 to engage with the first linkage block 244.

As can be seen from the above, no matter how the first and second linkage blocks 244 and 252 are positioned when the ice bank 230 is assembled to the ice bank stand 220, the first linkage block 244 can always be smoothly engaged with the second linkage block 252 under the action of the ice crushing motor 250 and the elastic member, so that the second linkage block 252 drives the first linkage block 244 to rotate, and thus the positions of the first and second linkage blocks 244 and 252 do not need to be adjusted when the ice bank 230 is assembled, so that the assembly of the ice bank 230 is simple and convenient.

The ice bank 230 can be detachably disposed on the ice bank stand 220 by means of snap-fastening. Of course, in other embodiments, the ice bank 230 can be detachably disposed on the ice bank bracket 220 by fastening with a hook or a magnet.

In the embodiment of the present application, as shown in fig. 9, the ice bank stand 220 has a first sidewall 222 and a second sidewall 223 disposed opposite to each other, and both the first sidewall 222 and the second sidewall 223 are disposed parallel to the thickness direction of the door body 10. The edges of the first side wall 222 and the second side wall 223 are provided with hooks 224. The hook 224 protrudes from the edges of the first side wall 222 and the second side wall 223, and the hook 224 is bent toward the ice maker 20, so that a gap is formed between the hook 224 and the first side wall 222 and the second side wall 223. The number of the hooks 224 may be one, two, or more, and in the embodiment of the present application, two hooks 224 are respectively disposed at the edges of the first side wall 222 and the second side wall 223, but the embodiment of the present application does not limit the specific number of the hooks 224.

Accordingly, as shown in fig. 4, the ice bank 230 has third and

fourth sidewalls

231 and 232 disposed opposite to each other, and each of the third and

fourth sidewalls

231 and 232 is disposed parallel to the thickness direction of the door body 10. The edges of the third and

fourth sidewalls

231 and 232 extend with a stopper rib 233. The limiting rib 233 may be a sheet structure, and the limiting rib 233 is perpendicular to the thickness direction of the door 10. The limiting rib 233 is inserted into the gap to allow the ice bank 230 to be clamped with the ice bank bracket 220. The number of the limiting ribs 233 may be one, two, or more, and two limiting ribs 233 are respectively disposed at the edges of the third side wall 231 and the fourth side wall 232 in the drawings of the embodiment of the present application, but the embodiment of the present application does not limit the specific number of the limiting ribs 233, and only the number of the limiting ribs 233 needs to be the same as the number of the hooks 224.

As shown in fig. 9, the first side wall 222 and the second side wall 223 are further provided with a limiting hole 225. The limiting hole 225 may be a circular hole, and the limiting hole 225 may also be a square hole, and the specific shape of the limiting hole 225 is not limited in the embodiment of the present application; the number of the limiting holes 225 may be one, two, or more, and the specific number of the limiting holes 225 is not limited in the embodiment of the present application. As shown in fig. 4, the third sidewall 231 and the fourth sidewall 232 are further provided with a latch 234. The shape of the buckle 234 is adapted to the shape of the limiting hole 225, so that the buckle 234 is fastened to the limiting hole 225, thereby increasing the fastening strength between the ice bank 230 and the ice bank bracket 220. The number of the buckles 234 may be one, two, or more, and the specific number of the buckles 234 is not limited in the embodiment of the present application, and only the number of the buckles 234 is required to be consistent with the number of the limiting holes 225.

As shown in fig. 13, the ice bank 230 may include a first bank 235 and a second bank 236, the first bank 235 forming an ice storage compartment 2351 for receiving ice cubes manufactured by the ice making assembly 210, and the second bank 236 forming a crushed ice compartment 2361 for crushing the ice cubes. A second opening 2362 is penetratingly provided on a sidewall of the first container 235 connected to the second container 236, so that the ice storage compartment 2351 and the crushed ice compartment 2361 are communicated.

And the transmission shaft 240 includes a position-limiting section 241, a first mounting section 242, and a second mounting section 243. Limiting section 241 is located in crushing chamber 2361.

Discharge section 2351c is positioned on an underside of feed section 2351a and is in communication with feed section 2351 a. The first bottom wall 2351e forming the discharge section 2351c is curved in shape having a low middle and two high sides to allow ice cubes within the discharge section 2351c to slide down to the ice pushing member 270. Therefore, ice cubes in ice storage compartment 2351 slide to ice pushing component 270 under the action of gravity and are pushed out, so that ice cubes are not easy to remain in ice storage compartment 2351.

As shown in fig. 13, second container 236 may include a front case 2363 and a rear case 2364, wherein front case 2363 is fixedly coupled to first container 235, and rear case 2364 is mounted on front case 2363 and fixedly coupled to front case 2363 to form an ice crushing chamber 2361. The second opening 2362 penetrates the front case 2363 and the sidewall of the first container 235 connected to the front case 2363, thereby communicating the crushed ice compartment 2361 and the ice storage compartment 2351. And the lower portions of the front case 2363 and the rear case 2364 are provided with a third opening 2365 so that the pushed ice member 270 can be discharged from the third opening 2365 after being pushed into the crushing chamber 2361.

As shown in fig. 6, the ice pushing member 270 may include an ice pushing tray 271 disposed on the transmission shaft 240, and a plurality of second protrusions 272 are disposed on a side wall of the ice pushing tray 271 facing the ice crushing assembly 260. In the present embodiment, the second protrusions 272 are provided in total, and are uniformly arranged in the circumferential direction of the tray 271. When the ice pushing tray 271 is driven to rotate by the driving shaft 240, the second protrusions 272 stir the ice cubes in the discharging section 2351c, so that the ice cubes are shifted in the axial direction of the driving shaft 240, and the shifted ice cubes at the second opening 2362 can enter the crushed ice compartment 2361 along the second opening 2362.

The following describes a specific mounting structure of the ice pushing member 270 and the driving shaft 240 in further detail with reference to the accompanying drawings.

When the ice pushing member 270 is installed in the first installation section 242, the end of the first installation section 242 away from the limiting section 241 is installed with the first limiting member 246, and the ice pushing member 270 is sandwiched between the first limiting member 246 and the first limiting surface 2411, so as to limit the degree of freedom of the ice pushing member 270 in the axial direction.

In the embodiment of the present application, as shown in fig. 8, the first stopper member 246 includes a snap ring. Specifically, an annular clamping groove 2423 is formed at an end of the ice crushing motor 250, which is far away from the first mounting section 242. The inner wall of the snap ring has at least three first protrusions 2461, and each first protrusion 2461 is clamped in the clamping groove 2423 and generates a clamping force in the radial direction of the transmission shaft 240 to clamp the bottom of the clamping groove 2423. In order to facilitate the clamping ring to be installed in the clamping groove 2423, the side wall of the clamping ring is provided with a notch 2462, so that the clamping ring can deform under the action of external force, and the notch 2462 is enlarged. When the snap ring needs to be installed or disassembled, after the notch 2462 is made larger than the annular groove 2423 by using external force, the groove 2423 can penetrate through the notch 2462 along the radial direction. Of course, in other embodiments, the first limiting member 246 can be a latch or the like disposed on the first mounting section 242.

As shown in fig. 6, ice crushing assembly 260 may include a stationary blade 261 and a movable blade 262. One end of the ice-fixing blade 261 is fixed on the side wall of the crushed ice chamber 2361, and the other end is sleeved on the second mounting section 243 in a hollow manner. The movable ice blade 262 is sleeved on the second mounting section 243 and rotates synchronously with the second mounting section 243.

Wherein, ice fixing blade 261 is located between second opening 2362 and third opening 2365 to hold ice pushed into crushed ice compartment 2361 by ice pushing component 270; the movable ice blade 262 can rotate in a first direction to cut ice cubes on the fixed ice blade 261 into crushed ice and push the crushed ice to the third opening 2365 for discharging, and the movable ice blade 262 can rotate in a second direction to lift the ice cubes on the fixed ice blade 261 to rotate around the axial direction of the transmission shaft 240 and then discharge the ice cubes from the third opening 2365.

As shown in fig. 7, a second limiting surface 2412 is arranged at the joint of the second mounting section 243 and the limiting section 241, and the side surface of the second mounting section 243 includes a second plane 2431 and a second arc surface 2332 which are arranged at intervals along the circumferential direction; one end of the second mounting section 243 close to the limiting section 241 is sleeved with a plurality of shaft sleeves 247, all the shaft sleeves 247 are clamped between the second limiting surface 2412 and the side wall of the crushed ice chamber 2361, and the ice cutter 261 is sleeved on the shaft sleeves 247.
