[0048] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides an ice making device, which comprises a compressor 230, a condenser 231, an expansion device 234 and a sand ice making device. The compressor 230 is connected to the condenser 231 by a pipeline, the condenser 231 is connected to the expansion device 234 by a pipeline, the expansion device 234 is connected to the sand ice making device by a pipeline, and the sand ice making device is connected to the compressor 230 by a pipeline. A refrigerant flows in the pipeline, and the refrigerant can circulate between the compressor 230, the condenser 231, the expansion device 234 and the sand ice making device.

[0049] The compressor 230 compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then the high-temperature and high-pressure gaseous refrigerant enters the condenser 231. After the high-temperature and high-pressure gaseous refrigerant releases heat to the outside through the condenser 231, the high-temperature and high-pressure gaseous refrigerant is converted into liquid refrigerant. Then the liquid refrigerant is depressurized by the expansion device 234 and enters the sand ice making device. After the sand ice making device absorbs heat, the liquid refrigerant is vaporized and then input into the compressor 230. In this way, the refrigerant can carry cold energy to the sand ice making device after passing through the condenser 231 and the expansion valve, and the sand ice making device can use the cold energy of the refrigerant to make sand ice.

[0050] Specifically, referring to Figure 3 and Figure 4The ice slush preparation device comprises an ice making barrel 100, a cooling supply part 200, a stirring shaft 300, stirring blades 310 and ice crushing blades 320. The ice making barrel 100 is formed with an ice making cavity 110, a water inlet 111 and an ice slush outlet 112. The ice making barrel 100 is in the form of a barrel and has a bottom wall 120 and a circumferential side wall 121 surrounding the bottom wall 120. The bottom wall 120 and the circumferential side wall 121 jointly form the ice making cavity 110. The water inlet 111 and the ice slush outlet 112 are both arranged on the circumferential side wall 121 of the ice making cavity 110. The water inlet 111 extends to the outer surface of the ice making barrel 100, so as to receive an external water source and add drinking water into the ice making cavity 110. The ice slush outlet 112 is in communication with an ice slush nozzle 140 arranged on the outer surface of the ice making barrel 100, so as to deliver the prepared ice slush to a user through the ice slush nozzle 140. The water inlet 111 is located on the side of the ice slush outlet 112 away from the bottom wall 120, so that the water inlet 111 is higher than the ice slush outlet 112, thereby avoiding the ice slush or ice block from blocking the water inlet 111.

[0051] The cooling supply part 200 is connected with the expansion part 234 and the compression part pipeline respectively, so that the refrigerant can carry cold energy through the cooling supply part 200, and the cooling supply part 200 can exchange heat with the ice making barrel 100, so as to transfer the cold energy of the refrigerant to the ice making barrel 100. In this way, after the drinking water is added into the ice making cavity 110 through the water inlet 111, the cold energy received by the ice making barrel 100 can make the drinking water in the ice making cavity 110 freeze.

[0052] Further, the stirring shaft 300 is rotatable about its own axis and movably arranged in the ice making cavity 110 along the direction of its own axis. Specifically, in the embodiment of the application, the stirring shaft 300 extends longitudinally along the up-down direction, so that the stirring shaft 300 can move up and down in addition to rotation. Figure 3 The stirring blades 310 are arranged on the circumferential side wall 121 of the stirring shaft 300, and the ice crushing blades 320 are arranged on the end of the stirring shaft 300 in the direction of its own axis and towards the bottom wall 120. The ice crushing blades 320 are made of hard alloy material, and the end face of the ice crushing blades 320 is in the form of a conical drilling structure.

[0053] In actual use, the stirring shaft 300 includes a first position and a second position in the process of moving along the direction of its own axis, and the first position is located above the second position. When the ice slush needs to be prepared, the stirring shaft 300 can be controlled to be located at the first position. At this time, the drinking water is added into the ice making cavity 110 through the water inlet 111, and the water surface of the drinking water is controlled to be lower than the ice crushing blades 320.

[0054] Afterwards, the cooling element 200 outputs cold energy to the ice making barrel 100 for a period of time, and the drinking water in the ice making cavity 110 will freeze into ice blocks. At this time, the stirring shaft 300 can be controlled to rotate and move downward at the same time. The stirring shaft 300 will drive the ice crushing blade 320 to rotate and move downward at the same time, and the ice blocks will be drilled layer by layer through the high-speed rotation of the ice crushing blade 320 and the axial feeding, so as to crush the ice blocks into fine ice slurry, until the stirring shaft 300 moves to the second position, at which time the ice crushing blade 320 approaches the bottom wall 120 of the ice making cavity 110.

[0055] Finally, the stirring shaft 300 is rotated in reverse, and the stirring shaft 300 is controlled to move from the second position to the first position. At this time, the stirring shaft 300 drives the stirring blade 310 to rotate and move upward, and the ice slurry is transmitted to the ice slurry outlet 112 on the circumferential side wall 121 through the spiral stirring blade 310, so that the ice slurry outlet 112 can output fine ice slurry outward.

[0056] The ice slurry preparation device 10 described above first adds a certain amount of drinking water into the ice making cavity 110 through the water inlet 111, and the cooling element 200 transmits cold energy to the ice making barrel 100. The drinking water in the ice making barrel 100 will form ice blocks. Afterwards, the stirring shaft 300 drives the ice crushing blade 320 to rotate and move downward, so that the ice crushing blade 320 can drill the ice blocks layer by layer to crush the ice blocks into fine ice slurry. Finally, the stirring shaft 300 drives the stirring blade 310 to rotate in reverse and move upward, so that the spiral stirring blade 310 can transmit the ice slurry to the ice slurry outlet 112, completing the preparation and output of the ice slurry. Compared with the traditional manual transfer of ice blocks, the ice slurry preparation device 10 described above does not require manual intervention throughout the process, can realize the automatic process of ice making and ice crushing, and realizes the efficient preparation and high-quality output of the ice slurry.

[0057] In some embodiments of the present application, referring to Figure 3 and Figure 4 , the ice slurry preparation device includes a power assembly 400, a vertical transmission assembly 500, and a rotary transmission assembly 600. The rotary transmission assembly 600 communicates the power assembly 400 and the stirring shaft 300. The power assembly 400 drives the stirring shaft 300 to rotate around its own axis via the rotary transmission assembly 600. The vertical transmission assembly 500 communicates the power assembly 400 and the stirring shaft 300. The power assembly 400 drives the stirring shaft 300 to move along the direction of its own axis via the vertical transmission assembly 500.

[0058] Thus, the power of the power assembly 400 is converted into the rotation of the stirring shaft 300 around its own axis or the movement of the stirring shaft 300 along its own axis direction by different transmission assemblies. And the power of the power assembly 400 can be transmitted as two independent power paths by the vertical transmission assembly 500 and the rotary transmission assembly 600, which can improve the coordination of the rotation and feeding movement of the ice crushing blade 320 and thus improve the ice crushing efficiency.

[0059] In some embodiments, the vertical transmission assembly 500 includes a screw rod 510 and a nut 520, both of which extend longitudinally along the axis of the stirring shaft 300 and are threadedly connected to each other. One of the screw rod 510 and the nut 520 is drivingly connected to the power assembly 400, and the other is connected to the stirring shaft 300. The power assembly 400 is configured to drive one of the screw rod 510 and the nut 520 to rotate relative to the other. Thus, when the screw rod 510 and the nut 520 rotate relative to each other, the nut 520 will move along the axial direction of the screw rod 510, thereby realizing the relative movement of the nut 520 relative to the screw rod 510 along the axis of the stirring shaft 300, and further driving the stirring shaft 300 to move along its own axis.

[0060] Further, the rotary transmission assembly 600 includes a guide column 610 and a guide sleeve 620, both of which extend longitudinally along the axis of the stirring shaft 300, and the guide column 610 is arranged in the guide sleeve 620. One of the guide column 610 and the guide sleeve 620 is drivingly connected to the power assembly 400, and the other is drivingly connected to the stirring shaft 300. The power assembly 400 is configured to drive the guide column 610 and the guide sleeve 620 to rotate around the axis of the stirring shaft 300, thereby driving the stirring shaft 300 to rotate around its own axis.

[0061] When the screw rod 510 and the nut 520 rotate relative to each other, the stirring shaft 300 will move along its own axis. At this time, the guide column 610 will move in the guide sleeve 620 along with the movement of the stirring shaft 300, so that the guide column 610 can adapt to the axial movement of the stirring shaft 300, and the guide column 610 and the guide sleeve 620 can also limit and guide the movement of the screw rod 510 and the nut 520, avoiding the screw rod 510 and the nut 520 from rotating together.

[0062] In a specific embodiment, referring to Figure 3 and Figure 4The ice slush preparation device 10 further comprises a transmission turntable 330, which is coaxially arranged at one end of the stirring shaft 300 away from the bottom wall 120. The transmission turntable 330 is in transmission connection with the vertical transmission assembly 500 and the rotary transmission assembly 600. The power assembly 400 drives the transmission turntable 330 to move along the axis of the stirring shaft 300 through the vertical transmission assembly 500 and to rotate around the axis of the stirring shaft 300 through the rotary transmission assembly 600, and finally drives the stirring shaft 300 to rotate or move along its own axis through the transmission turntable 330.

[0063] Specifically, one end of the lead screw 510 is connected with the power assembly 400 to drive the lead screw 510 to rotate around its own axis through the power assembly 400, and the other end of the lead screw 510 is in threaded connection with one end of the nut 520, and the other end of the nut 520 is connected with the center of the transmission turntable 330. Moreover, one end of the guide sleeve 620 is connected with the power assembly 400 to drive the guide sleeve 620 to rotate around the axis of the stirring shaft 300 through the power assembly 400, and one end of the guide column 610 is arranged in the guide sleeve 620, and the other end of the guide column 610 is connected with the transmission turntable 330.

[0064] In this way, when the lead screw 510 rotates around itself, the lead screw 510 and the nut 520 produce relative motion, and the nut 520 moves upward or downward along the lead screw 510, so as to drive the transmission turntable 330 to move upward or downward through the nut 520. Meanwhile, when the guide sleeve 620 rotates around the axis of the stirring shaft 300, the guide column 610 rotates around the axis of the stirring shaft 300 together with the guide sleeve 620, and further drives the transmission turntable 330 to rotate around the axis of the stirring shaft 300. Moreover, when the transmission turntable 330 moves upward or downward, the guide column 610 moves upward or downward together with the transmission turntable 330, so that the movement of the transmission turntable 330 in the axis direction of the stirring shaft 300 does not interfere with the rotation of the transmission turntable 330.

[0065] Further, in order to improve the reliability of transmission, the guide sleeve 620 and the guide column 610 arranged in the guide sleeve 620 are a group of guide members, and the guide members include multiple groups, and all the guide members are arranged at intervals around the axis of the transmission turntable 330. The multiple groups of guide members simultaneously drive the transmission turntable 330 to move, so that the rotation of the transmission turntable 330 is more stable. Moreover, the multiple groups of guide members are arranged at the center of the transmission turntable 330 in cooperation with the nut 520, so that the transmission turntable 330 can also be more stable when rising or falling, and the problem of inclination of the transmission turntable 330 is reduced.

[0066] In some embodiments, in order to drive the vertical transmission assembly 500 and the rotary transmission assembly 600, the power assembly 400 comprises a driving motor 410, an output gear 420 and a speed reduction structure 430, the driving motor 410 has an output shaft 411, the output gear 420 is arranged circumferentially on the output shaft 411, the rotary transmission assembly 600 further comprises a gear disc 630, the gear disc 630 is engaged with the output gear 420, and each guide sleeve 620 is arranged on the gear disc 630 away from one end of the guide column 610, so as to drive the output gear 420 to rotate through the output shaft 411, drive the gear disc 630 to rotate through the output gear 420, drive all the guide sleeves 620 to rotate through the gear disc 630, and finally drive the stirring shaft 300 to rotate around its own axis through the guide sleeves 620 and the guide column 610.

[0067] The speed reduction structure 430 has an input end 431 and an output end 432, the input end 431 is connected with the output shaft 411, and the output end 432 is connected with the screw rod, the speed reduction structure 430 transmits the rotation of the output shaft 411 to the screw rod after speed reduction, so as to drive the screw rod to rotate, and finally drive the stirring shaft 300 to move in the axis direction through the relative movement of the screw rod and the nut 520. It can be understood that in other embodiments, the output gear 420 can also be used to drive the screw rod to rotate, and the output end 432 drives the guide sleeve 620 to rotate around the axis of the stirring shaft 300. Further, a avoiding hole 131 is arranged in the center of the gear disc 630, the screw rod is arranged in the avoiding hole 131, so that the screw rod can pass through the gear disc 630 and be connected with the nut 520.

[0068] The ice slush preparation process of the ice slush preparation device 10 will be described below. Figure 4

[0069] When ice slush needs to be prepared, a certain amount of drinking water is added into the ice making cavity 110 through the water inlet 111, and then the cold supply part 200 is controlled to transfer cold to the ice making barrel 100, so that the drinking water in the ice making cavity 110 is frozen. At this time, the driving motor 410 controls the output shaft 411 to rotate forward, the output shaft 411 drives the gear disc 630 to rotate through the output gear 420, and the output shaft 411 also drives the lead screw 510 to rotate through the speed reduction structure 430, the rotation of the gear disc 630 drives the transmission turntable 330 to rotate through the guide sleeves 620 and the guide columns 610, the rotation of the lead screw 510 drives the transmission turntable 330 to move downward, and finally the stirring shaft 300 and the ice crushing blade 320 are fed downward while rotating, so as to drill and crush the ice block layer by layer, and the ice block is crushed into fine ice slush.

[0070] ​When the ice crushing blade 320 moves downward for a distance, the output shaft 411 can be controlled to reverse, thereby driving the gear plate 630 to reverse through the output gear 420, and driving the lead screw 510 to reverse through the speed reduction structure 430, finally driving the transmission turntable 330 to reverse while the transmission turntable 330 also moves upward, finally realizing that the stirring blade 310 moves upward while rotating, thereby driving the slush in the ice making cavity 110 to the slush outlet 112 through the spiral structure, completing the preparation of the slush.

[0071] It should be noted that in other embodiments, the vertical transmission mechanism can also be a linear module, and the rotary transmission mechanism can also be a gear structure, etc. The vertical transmission mechanism and the rotary transmission mechanism can select existing transmission structures, which are not limited herein.

[0072] In some embodiments, the ice making barrel 100 has an opening 122 communicating with the ice making cavity 110, and the slush preparation device 10 further comprises a cover assembly 130, and the power assembly 400 is arranged outside the ice making cavity 110, and the vertical transmission assembly 500 and the rotary transmission assembly 600 pass through the opening 122. In this way, the driving motor 410 of the power assembly 400 is arranged outside the ice making cavity 110, avoiding the influence of the low temperature in the ice making cavity 110 on the driving motor 410, the guide column 610 and the guide sleeve 620 of the vertical transmission device pass through the opening 122, and the lead screw 510 and the nut 520 of the rotary transmission device pass through the opening 122, so as to transmit power of the power assembly 400 to the stirring shaft 300 to drive the stirring blade 310 and the ice crushing blade 320 to act.

[0073] Further, the slush preparation device 10 further comprises a cover assembly 130, the cover assembly 130 covers the opening 122 and has a plurality of avoiding holes 131 passing through, the plurality of guide columns 610 of the vertical transmission device pass through the plurality of avoiding holes respectively, and the nut 520 of the rotary transmission device passes through one of the avoiding holes.

[0074] Specifically, in an embodiment, the cover assembly 130 comprises an ice tank cover 132 and a silica gel cover 133, the ice tank cover 132 is arranged on the ice making barrel 100 and covers the opening 122, a through hole is arranged in the middle of the ice tank cover 132, the silica gel cover 133 covers the through hole, and the silica gel cover 133 is in interference fit with the inner wall of the through hole to tightly plug the silica gel cover 133 on the ice tank cover 132. The silica gel cover 133 is provided with the plurality of avoiding holes as described above, when the guide column 610 and the nut 520 pass through the avoiding holes, the guide column 610 and the nut 520 can be in interference fit with the inner wall of the avoiding holes to seal the gap between the avoiding holes and the guide column 610 or the nut 520 through the silica gel cover 133, further reducing the heat loss in the ice making cavity 110 and improving the ice making efficiency.

[0075] In some embodiments, referring to Figure 3 , the ice slush preparation device 10 further comprises a proximity switch 150 arranged on the bottom wall 120 of the ice making cavity 110, the proximity switch 150 is used to detect the distance between itself and the ice crushing blade 320, and when the proximity switch 150 detects that the distance between the ice crushing blade 320 and itself is less than or equal to a preset threshold, the proximity switch 150 sends a stop signal to the driving motor 410, and after the driving motor 410 stops rotating, the driving motor 410 reverses to drive the stirring blade 310 to rise, thereby realizing the ice slush ice outlet.

By winding the cooling pipe 201 on the outer wall of the ice making barrel 100, the contact area of the cooling pipe 201 and the ice making barrel 100 can be increased. Alternatively, the cooling pipe 201 is a copper pipe, which is wound on the outer wall of the ice making barrel 100 by brazing process.

[0077] Further, the ice making device further comprises an ice cube preparation device 20, the ice cube preparation device 20 comprises an ice cube tray 710 and a spraying member, the spraying member is used to spray drinking water to the ice cube tray 710, the cooling pipe 201 passes through the ice cube tray 710, so that the cooling member 200 as the cooling pipe 201 can also exchange heat with the ice cube tray 710 and transmit the cooling capacity to the ice cube tray 710, so as to cooperate with the drinking water sprayed by the spraying member, so that the ice cube tray 710 can generate ice cubes, thereby realizing the preparation of ice cubes. In this way, through the above-mentioned ice making device, ice cubes can also be prepared through the ice cube preparation device 20 while ice slush is prepared through the ice slush preparation device 10, so as to fully utilize the cooling capacity in the cooling pipe 201, and at the same time, the different use requirements of users can also be met, thereby effectively improving the practicability of the ice making device.

[0078] It can be understood that in other embodiments, the cooling member 200 can also be an evaporative plate, the evaporative plate circulates the refrigerant, and the evaporative plate is attached to the ice making barrel and the ice cube tray 710 to transmit the cooling capacity to the ice making barrel and the ice cube tray 710, as long as the cooling member 200 can transmit the cooling capacity to the ice making barrel and the ice cube tray 710.

The cold supply pipeline 201 includes a first branch 220, a second branch 221 and a third branch 223, the first branch 220 is communicated with the first three-way outlet 212 and the third branch 223, the second branch 221 is communicated with the second three-way outlet 213 and the third branch 223, the first branch 220 has a first evaporation section 240, the first evaporation section 240 is located in the ice bin 710, and the third branch 223 has a second evaporation section 241, the second evaporation section 241 is wound around the ice-making bucket 100 and is communicated with the compressor 230.

[0080] Therefore, if the user only needs smoothies, the three-way valve 210 can be controlled to communicate the three-way inlet 211 with the second three-way outlet 213 and disconnect the three-way inlet 211 from the first three-way outlet 212, so that all the refrigerant after passing through the three-way valve 210 is input to the second branch 221 and finally to the third branch 223. At this time, the refrigerant does not pass through the ice bin 710, so that all the cold energy can be transmitted to the ice-making bucket through the second evaporation section 241, so that the drinking water in the ice-making bucket can be quickly frozen.

[0081] When the user needs ice cubes and smoothies at the same time, the three-way valve 210 can be controlled to communicate the three-way inlet 211 with the first three-way outlet 212 and disconnect the three-way inlet 211 from the second three-way outlet 213, so that the refrigerant after passing through the three-way valve 210 is input to the first branch 220 to transmit part of the cold energy to the ice bin 710 through the first evaporation section 240, and then the refrigerant is input to the third branch 223 to transmit the remaining cold energy to the ice-making bucket through the second evaporation section 241, so that ice is made in the ice bin 710 at the same time as ice is made in the ice-making bucket by using the residual cold energy, thereby realizing the preparation of smoothies and ice cubes at the same time.

[0082] In an embodiment, the expansion device 234 includes an ice bin capillary 250 and an ice-making bucket capillary 251, the three-way inlet 211 is connected with the condenser 231 pipeline, the first three-way outlet 212 is communicated with the first branch 220 through the ice bin capillary 250, and the second three-way outlet 213 is communicated with the second branch 221 through the ice-making bucket capillary 251. In addition, the ice-making device further includes a one-way valve 260, the one-way valve 260 is communicated with the first branch 220 and the third branch 223 to avoid the backflow of the refrigerant in the second branch 221 to the first branch 220 through the one-way valve 260.

[0083] In some embodiments, a drying filter 261 is further arranged between the three-way valve 210 and the condenser 231, so as to remove the residual moisture in the refrigerant through the drying filter 261, prevent ice blockage, reduce the corrosion of the moisture to the pipeline, and reduce the impurities in the refrigerant, and prevent the ice tray 710 capillary 250 and the ice tank capillary 251 from being blocked.

The drawn water is divided into two parts, one part flows directly into the ice block preparation device 20, and the other part flows towards the solenoid valve 740 and finally enters the ice-making cavity 110 through the water inlet 111. If the water in the ice-making cavity 110 reaches the required amount for ice making, the solenoid valve 740 can be closed to stop adding water to the ice-making cavity 110. The part entering the ice block preparation device 20 can be sprayed onto the surface of the ice tray 710 through the spraying element of the ice block preparation device 20 for making ice blocks.

[0085] Specifically, the ice-making device further comprises a quick plug three-way valve 750, an ice tray water inlet pipe 751, and a water inlet pipe 752. The circulating pump 730 is connected to the quick plug three-way valve 750 through the water inlet pipe 752, the ice tray water inlet pipe 751 is connected to the quick plug three-way valve 750 and the ice tray 710, and the quick plug three-way valve 750 is further connected to the solenoid valve 740, so as to divide the water drawn by the circulating pump 730 through the quick plug three-way valve 750.

[0086] It can be understood that in some other embodiments, the ice-making device is a shaved ice machine, that is, the ice-making device can not include the ice block preparation device 20, but only includes the ice slush preparation device 10.
