[0039] The utility model will be further described in detail below in combination with the drawings and specific embodiments, but not as the limitation of the utility model.

[0040] Referring to Figures 1 to 8 As shown in the figure, according to the embodiment of the utility model, an ice making device is provided, the ice making device includes ice crushing chamber 10, ice knife subassembly 20, grid filter structure 30 and ice outlet 40, and the ice knife subassembly 20 is arranged in the ice crushing chamber 10;The grid filter structure 30 is arranged at the inner wall of the ice crushing chamber 10, and the grid filter structure 30 has a plurality of grid holes 31 for passing ice pieces;The inside of the ice crushing chamber 10 is communicated with the ice outlet 40 through the grid hole 31 of the grid filter structure 30.

[0041] The ice-making device can guarantee the broken ice breaking quality, can better separate the whole ice and the broken ice, truly realizes the effect of "broken ice without ice block and whole ice without ice debris", and improves user satisfaction.

[0042] Preferably, the grid filter structure 30 is located at the bottom of the broken ice chamber 10, and the grid filter structure 30 is located below the ice cutter assembly 20.

[0043] Under the action of gravity, the ice block is directly dropped on the grid filter structure 30 located at the bottom of the broken ice chamber after being cut by the ice cutter assembly 20, and the broken ice block meeting the size requirement can pass through the grid hole 31 at the first time. The above structure cooperation fully utilizes the gravity effect, so that the broken ice block can be quickly discharged, and the ice discharging efficiency is improved. Moreover, the broken ice block or broken ice residue can directly enter the ice discharging opening without being left in the broken ice chamber, so that the separation effect of the whole ice block and the broken ice block is guaranteed.

[0044] In order to further improve the ice discharging efficiency, a plurality of grid holes 31 are arranged at intervals, and the total passing area of all the grid holes 31 is less than or equal to the cross-sectional area of the ice discharging opening 40.

[0045] Through the cooperation of the above structure, even if the ice cutter assembly 20 rotates at high speed and cuts and breaks a large amount of broken ice, the large amount of broken ice can pass through the grid hole 31 and enter the ice discharging opening. Since the total passing area of the grid hole 31 is not higher than the cross-sectional area of the ice discharging opening, a large amount of broken ice will not block the ice discharging opening, so that the ice discharging opening can always maintain high ice block passing efficiency.

[0046] Preferably, referring to Figures 1 to 4 In the embodiment, the ice-making device further comprises a whole ice channel 50, the inner wall of the broken ice chamber 10 is provided with a whole ice outlet 11, a first end of the whole ice channel 50 is in communication with the whole ice outlet 11, and a second end of the whole ice channel 50 is in communication with the ice discharging opening 40.

[0047] The whole ice outlet 11 is located at a position above the grid filter structure 30, and the whole ice outlet 11 is higher than the grid holes 31

[0048] The whole ice channel 50 and the ice outlet 40 are formed by the shell structure of the ice making device. The broken ice outlet (formed by multiple grid holes) is separated from the whole ice outlet, and the whole ice outlet is arranged at a position above the broken ice outlet side. In this design, the whole ice block is pushed by the ice knife assembly (cutter) to the bottom of the broken ice chamber and then lifted up by a distance before reaching the whole ice outlet, so as to ensure that there is no broken ice in the whole ice, so that the whole ice and the broken ice can be better separated.

[0049] In combination Figures 2 to 7 As shown, the ice knife assembly 20 includes a fixed knife 21 and a rotating knife 22;

[0050] The fixed knife 21 is fixedly arranged in the broken ice chamber 10;

[0051] The rotating knife 22 is rotatably installed in the broken ice chamber 10;

[0052] The rotating knife 22 intermittently crosses the fixed knife 21 during rotation to complete cutting of the broken ice.

[0053] The cooperation of the fixed knife and the rotating knife can cut the broken ice. The rotating knife can push the whole ice block around the fixed knife into the whole ice outlet during rotation away from the fixed knife or rotation around the fixed knife. In this way, the whole ice and the broken ice can be effectively separated.

[0054] Referring to Figure 5 In this embodiment, the top of the broken ice chamber 10 is provided with an ice inlet 12, and the fixed knife 21 is arranged at a position between the ice inlet 12 and the whole ice outlet 11;

[0055] The first side of the fixed knife 21 faces the ice inlet 12, and the second side of the fixed knife 21 faces the whole ice outlet 11;

[0056] The rotating direction of the rotating knife 22 has a first rotating direction and a second rotating direction which are completely opposite. When the rotating knife 22 rotates along the first rotating direction, the rotating knife 22 can repeatedly cut the broken ice on the grid filter structure 30. When the rotating knife 22 rotates along the second rotating direction, the rotating knife 22 pushes the whole ice block entering the ice inlet 12 around the fixed knife 21 and pushes it into the whole ice outlet 11.

[0057] The fixed blade 21 is positioned between the ice inlet 12 and the solid ice outlet 11. This ensures that during ice crushing, ice entering through the ice inlet 12 must be cut by the fixed blade before entering the outlet. Some ice blocks will not enter the solid ice channel from the outlet without being cut, even when the rotating blade is spinning at high speed, thus guaranteeing that all ice blocks are cut and crushed, effectively ensuring the ice crushing effect. When solid ice is required, the rotating blade only needs to perform a second rotation to push the solid ice block past the fixed blade into the solid ice outlet, ensuring the separation of crushed and solid ice.

[0058] Preferably, when the rotating blade 22 rotates along the first direction, the rotating blade 22 rotates circumferentially in the direction of the ice inlet 12 toward the fixed blade 21;

[0059] When the rotating blade 22 rotates along the second direction, the rotating blade 22 rotates circumferentially along the direction away from the fixed blade 21 from the ice inlet 12.

[0060] Combination Figure 4 The orientation of the ice-making device shown in the diagram is used to illustrate the direction of rotation. The first rotation of the rotating blade is in... Figure 4 The middle part rotates clockwise, and the second direction of rotation of the rotating blade is... Figure 4 Rotate counterclockwise.

[0061] When the rotating blade rotates clockwise, its movement intersectes with that of the fixed blade, cutting the ice into smaller pieces. These smaller pieces then fall onto a grid filter structure at the bottom of the ice-crushing chamber. This grid filter structure allows larger ice pieces to remain inside the chamber, where they continue to be broken down by the rotating blade until they are large enough to pass through the grid holes before falling into the outlet. This ensures the quality of the broken ice. When the rotating blade rotates counterclockwise, the small gap between it and the inner wall of the ice-crushing chamber pushes whole ice pieces to the whole ice outlet, where they then fall through the whole ice channel into the outlet. Therefore, the interaction between the fixed and rotating blades allows for the output of either broken or whole ice.

[0062] In order to further integrate the structure and reduce the volume of the ice-making device, in this embodiment, a drive shaft 60 is installed in the ice crushing chamber 10, and the drive shaft 60 is equipped with a drive motor.

[0063] The fixed blade 21 is connected to the drive shaft 60. One end of the fixed blade 21 rotates relative to the drive shaft 60, and the other end of the fixed blade 21 is fixedly connected to the inner wall of the ice crushing chamber 10.

[0064] The connecting end of the rotating blade 22 is driven to connect with the driving shaft 60, and the moving end of the rotating blade 22 rotates circumferentially.

[0065] The driving shaft 60 is fixedly connected with the output shaft of the driving motor at one end and is inserted into a circular hole in the side wall of the ice crushing chamber at the other end, so that the driving shaft 60 can rotate under the driving of the driving motor and further drive the rotary knife to rotate. The fixed connection point of the fixed knife can share an axle with the driving shaft of the rotary knife, so that part of the support structure of the fixed knife is saved, the occupied space of other matching structures is reduced, the structure is more integrated, the overall disassembly and maintenance are facilitated, and the volume of the ice making device is reduced.

[0066] Preferably, the fixed knife 21 is arranged adjacent to the ice inlet 12, and the other end of the fixed knife 21 is inserted into and fixed in the fixed groove 13 in the inner wall of the ice crushing chamber 10.

[0067] One end of the fixed knife is inserted into the fixed groove 13 in the inner wall of the ice crushing chamber, and the other end is only sleeved on the driving shaft and does not rotate with the shaft. The middle hole of the rotary knife is sleeved on the driving shaft and is fixedly connected with the driving shaft, so that it can rotate with the driving shaft. There is a shaft sleeve between the fixed knife and the rotary knife, which can fix the positions of the two. The arrangement of the fixed knife 21 adjacent to the ice inlet 12 can play a certain guiding role. When the whole ice block is needed, it will be drawn away from the fixed knife, and then the rotary knife will push it to rotate, so that the fixed knife plays a multiple effect.

[0068] Preferably, the rotary knife 22 has a sawtooth structure on the side facing the first direction of rotation, and has a smooth surface on the side facing the second direction of rotation.

[0069] The first side of the fixed knife 21 is a sawtooth structure, and the second side of the fixed knife 21 is a smooth surface.

[0070] The sawtooth structure of the rotary knife 22 cooperates with the sawtooth structure of the fixed knife 21, which can further improve the ice crushing effect and the stirring effect. The smooth surface of the rotary knife 22 cooperates with the smooth surface of the fixed knife 21, which further enables the whole ice block to be outputted in whole, improving the completeness of the whole ice block.

[0071] In combination Figure 6 And Figure 7 As shown in the drawings, the number of rotary knives 22 is multiple, the number of fixed knives 21 is multiple, and one fixed knife 21 is arranged between two adjacent rotary knives 22. Each rotary knife 22 has at least one blade.

[0072] The cooperation of multiple rotary knives and multiple fixed knives can increase the ice crushing efficiency, improve the ice output speed, and improve the user satisfaction. The number of rotary knives 22 is multiple and arranged in a direction, which can smoothly push the whole ice block out and prevent the whole ice block from sliding, achieving the effect of anti-skid.

[0073] Referring to Figure 8The ice making device further comprises an ice storage box 70 arranged at a top position of the ice making device, the ice storage box 70 being in communication with the crushed ice chamber 10 through the ice inlet 12; and the ice outlet 40 is located at a bottom position of the ice making device.

[0074] The ice storage box is used for storing whole ice blocks, and the ice storage box located at the top can utilize the gravity of the ice blocks to enter the crushed ice chamber without other power, thereby reducing energy consumption and structural complexity. The ice outlet located at the bottom can also utilize the gravity to make the ice blocks slide or drop and be discharged, thereby reducing energy consumption and structural complexity.
