[0039] This application provides an ice-crushing device to solve the problem of integrating whole ice dispensing and crushed ice dispensing. The following description will be provided in conjunction with the accompanying drawings.

[0040] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the ice-crushing device includes:

[0041] The shell 1 has an ice inlet 11, an ice crushing chamber 12 and an ice outlet 13 arranged sequentially from top to bottom;

[0042] An ice-crushing mechanism is installed inside the ice-crushing chamber 12; and,

[0043] Ice gate 2 is movably connected to housing 1. Ice gate 2 can move between a first position and a second position to change the size of ice outlet 13.

[0044] When the ice gate 2 is moved to the first position, it blocks at least part of the ice outlet 13 to allow ice fragments to pass through; when the ice gate 2 is moved to the second position, the ice outlet 13 is used to allow whole ice to pass through.

[0045] It should be noted that the ice-crushing mechanism refers to a structure that can shear and crush ice blocks. The ice selection gate 2 can change its position on the shell 1 by means of rotation, sliding, or other movements, thereby changing the size of the ice outlet 13.

[0046] Understandably, during ice crushing, the ice selection door 2 moves to the first position to prevent ice blocks from falling from the ice outlet 13. The ice blocks enter the ice crushing chamber 12 through the ice inlet 11 and are then crushed by the ice crushing mechanism. The shear force applied by the ice crushing mechanism to the ice blocks gives the crushed ice a certain inertia, which is then discharged from the ice outlet 13 under the action of inertia and gravity. When discharging whole ice, the ice selection door 2 moves to the second position to expose the ice outlet 13 as much as possible. The ice blocks pass through the ice inlet 11 and the ice crushing chamber 12 in sequence and are then discharged directly from the ice outlet 13. The ice crushing device of this application is mainly used in refrigerators, especially some refrigerators equipped with ice makers. The ice blocks produced by the ice maker are stored directly in the ice storage box on one hand, and supplied to the ice crushing device to produce crushed ice on the other hand. In this application, the channels for discharging whole ice and crushed ice are integrated into the ice crushing device, and the ice selection door 2 can be used to distinguish between discharging whole ice and crushed ice. The structure is simple and improves space utilization.

[0047] In some embodiments, such as Figure 4 As shown, the ice-crushing mechanism includes:

[0048] Ice blade assembly 3 is fixedly connected inside housing 1 and positioned opposite to ice outlet 13; and...

[0049] The moving blade assembly 4 is movably connected inside the housing 1, and the moving blade assembly 4 and the fixed blade assembly 3 are staggered along the moving direction of the moving blade assembly 4.

[0050] Along the direction of movement of the moving blade assembly 4, the fixed blade assembly 3 has a fixed blade back side 312 and a fixed blade edge side 311. When the ice gate 2 is moved to the first position, it blocks at least part of the ice outlet 13 and the fixed blade edge side 311, and the fixed blade back side 312 is used to discharge broken ice; when the ice gate 2 is moved to the second position, the fixed blade edge side 311 is used to allow whole ice to pass through.

[0051] It should be noted that the blade back side 312 and blade edge side 311 of the fixed blade assembly 3 refer to the fact that the fixed blade assembly 3 includes multiple fixed blades 31, each of which has a blade edge side 311 and a blade back side 312. It is easy to imagine that the blade edge sides 311 and the blade back sides 312 of the multiple fixed blades 31 in the fixed blade assembly 3 all face the same direction. The moving blade assembly 4 has a blade edge side. The moving blade assembly 4 can move relative to the fixed blade assembly 3 by rotating or sliding. In this way, the fixed blade assembly 3 limits the ice block during the ice-breaking process, preventing the ice block from moving with the moving blade assembly 4. At the same time, the moving blade assembly 4 cuts the fixed ice block. It is easy to understand that the fixed blade edge 311 of the fixed blade assembly 3 limits the ice block, and the moving blade edge 411 of the moving blade assembly 4 cuts the ice block relative to the fixed blade edge 311.

[0052] It is understandable that "when the ice gate 2 is moved to the first position, at least part of the ice outlet 13 and the fixed blade edge 311 are blocked, and the fixed blade back edge 312 is used to discharge ice fragments" means that the cut ice fragments continue to move along the direction of movement of the moving blade group 4 under the action of inertia and the pushing action of the moving blade group 4, that is, along the fixed blade edge 311 pointing to the fixed blade back edge 312, and finally discharged under the action of gravity at least part of the ice outlet 13 that was never blocked.

[0053] "When the selected ice gate 2 is moved to the second position, and the blade side 311 of the fixed ice blade is used for the passage of whole ice" means that the ice exit 13 facing the blade side 311 of the fixed ice blade is not blocked by the selected ice gate 2, allowing whole ice to exit. The fixed ice blade assembly 3 is positioned opposite to the ice exit 13, meaning that the projection of the fixed ice blade assembly 3 onto the plane of the ice exit 13 along the direction of gravity is located in the middle of the ice exit 13, and the distance between the blade side 311 of the fixed ice blade and the opposite side wall of the ice exit 13 is greater than the distance between the back side 312 of the fixed ice blade and the opposite side wall of the ice exit 13.

[0054] For example, the moving blade assembly 4 is rotatably connected to the housing 1, and the rotation axis of the moving blade assembly 4 is set along the direction of gravity. The moving blade assembly 4 has opposing moving blade cutting edges 411 and moving blade back edges 412. In this way, the ice fragments generated by cutting in the horizontal direction can be discharged from the ice outlet 13 under the action of gravity after being freed from the restraint of the moving blade assembly 4 and the fixed blade assembly 3.

[0055] Alternatively, the moving blade assembly 4 is slidably connected to the housing 1 along a horizontal straight line. Two fixed blade assemblies 3 are provided on both sides of the moving blade assembly 4 along its sliding direction. The moving blade assembly 4 has two opposing moving blade cutting edges 411. Along the direction of gravity, the ice inlet 11, the ice outlet 13, and the two fixed blade assemblies 3 are arranged opposite each other. When removing whole ice, the ice selection gate 2 moves outside the two fixed blade assemblies 3, allowing whole ice to pass between them. When removing crushed ice, the ice selection gate 2 moves between the two fixed blade assemblies 3, allowing crushed ice to exit from the side of the two fixed blade assemblies 3 away from the moving blade assembly 4.

[0056] In some embodiments, the fixed ice blade assembly 3 can also be configured such that both opposite sides are fixed ice blade edges 311, and both opposite sides of the movable ice blade assembly 4 are movable ice blade edges 411. The movable ice blade assembly 4 is rotatably connected to the housing 1, and the movable ice blade assembly 4 and the fixed ice blade assembly 3 are staggered along the rotation direction of the movable ice blade assembly 4. In this way, the movable ice blade assembly 4 can break ice by rotating clockwise or counterclockwise. One of the two fixed ice blade edges 311 is always used to limit the ice block. Accordingly, moving the ice selection gate 2 to block the fixed ice blade edge 311 can break and release ice.

[0057] In some embodiments, such as Figure 4 As shown, a blocking member 5 is provided inside the housing 1. The blocking member 5 is located on the side of the ice outlet 13 facing the back side of the ice-fixing blade 312 and is spaced apart from the back side of the ice-fixing blade 312 to discharge broken ice.

[0058] It should be noted that the blocking element 5 is applicable to the fixed ice blade assembly 3, which has both a fixed ice blade cutting edge side 311 and a fixed ice blade back side 312. It can be understood that by setting the spaced blocking element 5 on the side of the fixed ice blade assembly 3 that discharges ice fragments, it is possible to prevent ice fragments from splashing onto the bottom surface of the ice crushing chamber 12 when they are discharged, thus avoiding the accumulation of ice fragments and thus preventing them from hindering the movement of the moving ice blade assembly 4.

[0059] In some embodiments, such as Figure 4 As shown, the blocking member 5 includes a plurality of blocking blocks 51, which are spaced apart from each other along a direction perpendicular to the direction of movement of the moving blade assembly 4 to allow the moving blade assembly 4 to pass through.

[0060] It is understandable that while blocking the ice shards, multiple blocking blocks 51 are spaced out to ensure the normal movement of the moving ice blade assembly 4.

[0061] In some embodiments, such as Figure 4 As shown, a movement channel 511 is formed between any two adjacent blocking blocks 51, and each movement channel 511 is used for one moving ice skate 41 of the moving ice skate assembly 4 to pass through.

[0062] It should be noted that the moving blade group 4 includes multiple moving blades 41. The multiple moving blades 41 of a moving blade group 4 can be arranged sequentially at intervals along its direction of movement, in which case the multiple moving blades 41 of a moving blade group 4 pass through their corresponding movement channels 511 sequentially; the multiple moving blades 41 of a moving blade group 4 can also be arranged at intervals along a direction perpendicular to its direction of movement, in which case a movement channel 511 is only for one moving blade 41 to pass through.

[0063] In some embodiments, such as Figure 5 and Figure 6 As shown, the fixed blade group 3 includes multiple fixed blades 31, which are arranged opposite each other and spaced apart along a direction perpendicular to the direction of movement of the moving blade group 4;

[0064] It is understandable that if the moving blade assembly 4 is rotatably connected to the housing 1, and its rotation axis is set along the direction of gravity, then multiple fixed blades 31 are spaced apart along the direction of gravity, and multiple fixed blades 31 are located on the same vertical line. In this way, the fixed blade assembly 3 can better limit the movement of the ice block.

[0065] In some embodiments, such as Figure 4 As shown, the moving blade assembly 4 includes multiple moving blades 41, which are spaced apart along the moving direction of the moving blade assembly 4;

[0066] Understandably, along the direction of movement of the moving blade assembly 4, multiple moving blades 41 can sequentially cut ice blocks, continuously producing ice fragments and improving ice-breaking efficiency.

[0067] In some embodiments, such as Figure 7 As shown, multiple moving blade groups 4 are arranged at intervals along a direction perpendicular to the direction of movement of the moving blade group 4, and the multiple moving blade groups 4 are staggered along the direction of movement of the moving blade group 4.

[0068] Understandably, if the moving blade assembly 4 is rotatably connected to the housing 1, the multiple moving blades 41 of the multiple moving blade assemblies 4 can form an arrangement in an approximately spiral shape. In this way, the multiple moving blades 41 can continuously cut the ice, further improving the ice-breaking efficiency.

[0069] In some embodiments, such as Figure 6 and Figure 7 As shown, the fixed blade group 3 includes multiple fixed blades 31, which are arranged opposite each other and spaced apart along a direction perpendicular to the direction of movement of the moving blade group 4;

[0070] The moving blade assembly 4 includes multiple moving blades 41, which are spaced apart along the moving direction of the moving blade assembly 4;

[0071] Multiple moving blade assemblies 4 are arranged at intervals along a direction perpendicular to the direction of movement of the moving blade assembly 4, and the multiple moving blade assemblies 4 are staggered along the direction of movement of the moving blade assembly 4.

[0072] Understandably, if the moving blade assembly 4 is rotatably connected to the housing 1, and its axis of rotation is set along the direction of gravity, then multiple fixed blades 31 are spaced apart along the direction of gravity, and the multiple fixed blades 31 are located on the same vertical line. In this way, the fixed blade assembly 3 can effectively limit the ice block. Multiple moving blades 41 of one moving blade assembly 4 can cut the ice block sequentially, continuously producing ice fragments; by further setting multiple moving blade assemblies 4, multiple moving blades 41 can continuously cut the ice block, further improving the ice-breaking efficiency.

[0073] In some embodiments, such as Figure 3 and Figure 4 As shown, the ice crushing device also includes a drive component 6 and a transmission component 7. The two ends of the transmission component 7 are connected to the drive component 6 and the ice selection gate 2, respectively. The housing 1 is provided with an arc-shaped slide 14. The drive component 6 is a linear motion drive component 6. The drive component 6 is used to drive the transmission component 7 to slide along the arc-shaped slide 14, so as to drive the ice selection gate 2 to rotate between the first position and the second position.

[0074] It should be noted that the linear motion drive component 6 refers to a structure that can drive in a straight line, such as a cylinder or electric cylinder. It can be understood that the linear motion of the drive component 6 is converted into the rotation of the ice gate 2 by the transmission component 7 that moves along the arc-shaped slide 14.

[0075] In some embodiments, such as Figure 3 As shown, both the drive component 6 and the arc-shaped slide 14 are located on the top of the housing 1;

[0076] The ice selection door 2 includes a shielding part 21 rotatably connected to the bottom of the housing 1 and a connecting part 22 connected to the shielding part 21. The connecting part 22 is located on the outer periphery of the housing 1 and is connected to one end of the transmission member 7.

[0077] It should be noted that the shielding part 21 refers to the portion on the ice selection gate 2 used to shield the ice outlet 13. It can be understood that the connecting part 22 located on the outer periphery of the housing 1 allows both the drive component 6 and the transmission component 7 to be positioned at the top of the housing 1, while the shielding part 21 is positioned at the bottom of the housing 1. This facilitates the production and installation of the drive component 6 and the transmission component 7.

[0078] In some embodiments, such as Figure 3As shown, the transmission component 7 is rotatably connected to the housing 1. One end of the transmission component 7 extends upward through the arc and is sleeved with the driving component 6. The other end of the transmission component 7 extends horizontally through the housing 1 and is sleeved with the connecting part 22. A torsion spring 8 is provided inside the housing 1. The two ends of the torsion spring 8 are respectively connected to the transmission component 7 and the housing 1.

[0079] Understandably, when the driving component 6 drives the transmission component 7 to rotate, the torsion spring 8 twists to store kinetic energy, while the transmission component 7 drives the ice-selecting door 2 to rotate to the first position. When the driving component 6 resets, the restriction on the transmission component 7 is released, and the transmission component 7 resets under the action of the torsion spring 8.

[0080] In some embodiments, such as Figure 7 As shown, the ice inlet 11 is positioned facing the back of the ice cutter 312 to allow whole ice to pass through the ice-crushing device. Thus, when the ice gate 2 is moved to the second position, the ice blocks can enter through the ice inlet 11 and be discharged directly from the ice outlet 13 along the direction of gravity.

[0081] This application also provides a refrigerator, including the ice crushing device described above. The specific structure of the ice crushing device is as described in the above embodiments. Since this refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0082] In some embodiments, the refrigerator further includes an ice maker and an ice storage box, wherein the ice outlet channel of the ice maker is connected to the ice inlet 11 of the ice crushing device, and the ice storage box is located below the ice outlet 13 of the ice crushing device.

Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, 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 indicated technical features.
