[0040] For the convenience of understanding the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween. The terms "upper", "lower", "inner", "outer", "vertical", "horizontal" and the like used in the specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0041] Unless otherwise defined, all technical and scientific terms used in the specification have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0042] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0043] As Figures 1-2 shown, the ice-making device 1 provided by one of the embodiments of the present application includes an ice-making cylinder 2, a screw rod 3, an evaporator 4 and a bottom cover 5. The ice-making cylinder 2 is provided with an ice-making cavity 21 and a mounting port 22 in communication. The screw rod 3 includes a rod body 31 and a spiral scraper 32 connected to each other. The spiral scraper 32 spirally extends along the axis (such as the axis OP shown in Figure 2 the rod body 31 and is located in the ice-making cavity 21. The rod body 31 is mounted to the mounting port 22, and the spiral scraper 32 is used to scrape off the ice generated in the ice-making cavity 21. The evaporator 4 is arranged in the ice-making cylinder 2, and the evaporator 4 is used to contain a cooling medium for transferring cold energy to the liquid to be frozen into the ice-making cylinder 2. The bottom cover 5 is connected to the ice outlet end 25 of the ice-making cylinder 2, and the bottom cover 5 is provided with an ice extrusion hole 51 in communication with the ice-making cavity 21. The center line of the ice extrusion hole 51 is arranged in parallel with the axis of the rod body 31.

[0044] The ice-making cylinder 2 is provided with a liquid inlet 24 communicating with the ice-making cavity 21, and the liquid inlet 24 is arranged away from the ice outlet end 25 of the ice-making cylinder 2. In the direction perpendicular to the axis of the ice-making cylinder 2, the diameter of the liquid inlet 24 near the one end of the ice-making cavity 21 is greater than the diameter of the liquid inlet 24 away from the one end of the ice-making cavity 21.

[0045] In use, the liquid to be frozen is introduced into the liquid inlet 24, and the liquid to be frozen flows towards the ice outlet end 25 of the ice-making cylinder 2 under the action of gravity when entering the ice-making cavity 21. The liquid to be frozen is frozen when flowing through the area where the evaporator 4 and the ice-making cylinder 2 are separated due to the cold energy transferred by the cooling medium introduced into the evaporator 4. When the screw 3 rotates, the spiral scraper 32 scrapes off the crushed ice, the crushed ice is transported to the ice outlet end 25 of the ice-making cylinder 2 along with the rotation of the rod body 31, and finally the ice body is sent out of the ice-making cavity 21 through the ice extrusion hole 51 of the bottom cover 5.

[0046] The ice-making device 1 of the embodiment of the present application is provided with the ice extrusion hole 51 on the bottom cover 5, which communicates with the ice-making cavity 21. When the supply of the cooling medium is stopped, the liquid in the ice-making cylinder 2 after the ice is melted can flow out of the ice-making cylinder 2 through the ice extrusion hole 51 under the action of gravity, and the liquid to be frozen introduced into the ice-making cylinder 2 can also be discharged from the ice-making cylinder 2 in time through the ice extrusion hole 51, thereby reducing the risk of hygiene problems such as fouling and bacteria growth caused by the liquid remaining in the ice-making cylinder 2, and being convenient to use.

[0047] In addition, since the diameter of the liquid inlet 24 increases in the direction towards the ice-making cavity 21, the flow rate of the liquid to be frozen entering the ice-making cavity 21 through the liquid inlet 24 will decrease, so that the liquid to be frozen flows along the inner wall surface of the ice-making cavity 21 under the action of the Coanda effect to form a liquid film with a predetermined thickness, and the cooling medium introduced into the evaporator 4 is frozen to form an ice film with a predetermined thickness, thereby avoiding the immersion of the screw 3 in the liquid to be frozen, reducing the risk of the rod body 31 of the screw 3 being stationary due to the constraint of the ice, facilitating the timely ice scraping of the spiral scraper 32 of the screw 3, reducing the risk of abnormal operation of the ice-making device 1, and being conducive to improving the stability of the ice-making device 1.

[0048] It should be understood that the Coanda effect (also known as the wall attachment effect) refers to the tendency of a fluid to flow along the surface of a convex object rather than deviating from the original flow direction. When there is surface friction between the fluid and the object surface through which the fluid flows, the fluid will flow along the object surface. In other words, when the liquid to be frozen flows from the liquid inlet 24 to the ice-making cavity 21, the liquid will flow along the inner wall surface of the ice-making cylinder 2 when flowing out of the liquid inlet 24.

[0049] In some embodiments, the number of liquid inlets 24 is multiple, and the multiple liquid inlets 24 are arranged in a ring around the ice making cavity 21. Compared with the case where only one liquid inlet 24 is arranged, the case where multiple liquid inlets 24 are arranged is advantageous in that the liquid to be frozen can flow into the ice making cavity 21 from multiple positions, so as to form a larger area of liquid film in the circumferential direction of the ice making cylinder 2, thereby facilitating the formation of a larger area of ice film when the cooling medium freezes the liquid film, facilitating the scraping of the ice film by the spiral scraper 32 of the screw 3 at more positions, and improving the ice making efficiency.

[0050] The shape of the liquid inlet 24 can be a circular truncated cone, an elliptical truncated cone, a prism, or other shapes, as long as the size of the diameter of the end of the liquid inlet 24 close to the ice making cavity 21 is greater than the size of the diameter of the end of the liquid inlet 24 away from the ice making cavity 21. In the present embodiment, the shape of the liquid inlet 24 is a circular truncated cone. It should be noted that the position of the liquid inlet 24 on the ice making cylinder 2 should be spaced apart from the position of the evaporator 4 arranged in a ring around the ice making cylinder 2, so as to reduce the risk that the liquid input into the ice making cavity 21 from the liquid inlet 24 is directly frozen.

[0051] In some embodiments, as shown in Figure 2 , the inner wall surface of the ice making cylinder 2 is provided with a spiral groove 23, and the spiral groove 23 is configured to extend in a first spiral line along the axis (such as the axis OP shown in Figure 2 ) of the ice making cylinder 2. Compared with other regions of the ice making cylinder 2 where the inner wall surface is not provided with the spiral groove 23, the inner wall surface of the spiral groove 23 is closer to the cooling medium in the evaporator 4, so that the liquid to be frozen in the spiral groove 23 will be frozen first, and then gradually freeze into the ice making cavity 21, which is advantageous in restricting the path of ice formation and facilitating the cleaning of the ice formation by the spiral scraper 32 of the screw 3.

[0052] Along the axis OP of the ice making cylinder 2, the cross-sectional shape of the spiral groove 23 can be triangular, circular arc, or other shapes, which can be set as needed. In some embodiments, the cross-sectional shape of the spiral groove 23 is triangular. By using the characteristic that a triangle has sharp corners, when the cooling medium transfers cold energy to the sharp corners of the triangular spiral groove 23, the liquid to be frozen in the spiral groove 23 at the sharp corners is more likely to freeze, which is advantageous in improving the efficiency of ice formation.

[0053] In some embodiments, as shown in Figure 2 and Figure 3As shown, the spiral groove 23 comprises a first wall surface 231 and a second wall surface 232, the first wall surface 231 and the second wall surface 232 intersect at a first intersection line 233, a plane coinciding with the axis OP of the ice making cylinder 2 is taken as a projection plane, the direction in which the axis OP of the ice making cylinder 2 is located is taken as a first direction X, the dimension of the first wall surface 231 in the first direction X in the orthographic projection of the projection plane is M1, the dimension of the second wall surface 232 in the first direction X in the orthographic projection of the projection plane is M2, M1>M2, M1>0, M2>0. In this way, the spiral groove 23 is arranged in an asymmetric shape, and the length of the first wall surface 231 extending from the first intersection line 233 relative to the second wall surface 232 is longer, the included angle F1 between the second wall surface 232 and a straight line perpendicular to the axis OP of the ice making cylinder 2 is greater than the included angle F2 between the first wall surface 231 and a straight line perpendicular to the axis of the ice making cylinder 2, so that when the ice in the spiral groove 23 is scraped by the spiral scraper 32, the direction of the resultant force of the force applied to the ice by the first wall surface 232 and the force applied to the ice by the blade surface of the spiral scraper 32 is along the axial direction of the rod body 31, thereby achieving the purpose of pushing the ice to move, which is beneficial to the spiral scraper 32 to better scrape the ice generated from the spiral groove 23, thereby further improving the ice making efficiency.

[0054] In some embodiments, as shown in Figure 2 With Figure 3 As shown, along the direction in which the spiral scraper 32 extends spirally, the included angle between the second wall surface 232 and the axis of the ice making cylinder 2 is A, and 80°≤A≤90° is satisfied, that is, the second wall surface 232 is in a nearly vertical relationship with the rod body 31 of the screw rod 3, which is beneficial to the second wall surface 232 to provide a supporting force to the ice generated in the spiral groove 23, so that the screw rod 3 can better push the ice growing from the spiral groove 23 into the ice making cavity 21, thereby improving the ice making effect.

[0055] In some embodiments, as shown in Figures 2-4 As shown, the ice making cylinder 2 comprises a first connecting seat 2a, a cylinder body 2b and a second connecting seat 2c, the first connecting seat 2a and the second connecting seat 2c are respectively connected to opposite ends of the cylinder body 2b, the first connecting seat 2a is provided with a plurality of first connecting holes 201 distributed at intervals, the second connecting seat 2c is provided with a plurality of second connecting holes 202 distributed at intervals, and the plurality of first connecting holes 201 and the plurality of second connecting holes 202 are used for connection to fix the cylinder body 2b at a desired position. The cylinder body 2b is provided with the spiral groove 23, the ice making cavity 21, the liquid inlet 24 and the mounting port 22, the liquid inlet 24 and the mounting port 22 are in communication with the ice making cavity 21, the liquid inlet 24 is used for introducing a liquid to be frozen into the cylinder body 2b, and the liquid to be frozen can be tap water, sugar water or other liquids as long as it can be condensed.

[0056] In some embodiments, please refer again to Figure 2The helical scraper 32 of the screw rod 3 spirally ascends along the axis of the rod body 31, and the direction of the helical scraper 32 spirally ascending is opposite to the direction of the helical groove 23 ascending, so as to facilitate the helical scraper 32 contacting the ice extending from the helical groove 23, thereby improving the scraping of the ice growing from the helical groove 23 by the helical scraper 32.

[0057] In some embodiments, please refer to Figure 5 and Figure 7 The evaporator 4 comprises a container body 41 and a flow guide fin 44 arranged in the container body 41, and the flow guide fin 44 is configured to spirally extend along the axis of the ice-making cylinder 2 in a second helical line, and the first helical line is parallel to the second helical line. The flow guide fin 44, the container body 41 and the outer wall surface of the ice-making cylinder 2 form a spiral channel 401, and the projection of the helical groove 23 is located in the spiral channel 401 in the direction perpendicular to the axis of the ice-making cylinder 2, and the spiral channel 401 is used to constrain the movement of the cooling medium along the preset path. Thus, under the action of the flow guide fin 44, the cooling medium is beneficially constrained to be transported along the spiral channel 401, so that the cooling medium uniformly transmits cold energy to the helical groove 23, and the ice formed in the ice-making cylinder 2 is beneficially guided to grow from the helical groove 23 first and then extend into the ice-making cavity 21, that is, the growth of the ice in the ice-making cylinder 2 is constrained, the ice generated from the helical groove 23 is timely scraped by the helical scraper 32 of the screw rod 3, the risk of the ice produced adhering to the helical scraper 32 is reduced, and the ice-making effect is improved. It should be noted that the first helical line is parallel to the second helical line, which means that the two helical lines are spaced apart by a preset distance along the axis OP of the ice-making cylinder 2 and do not intersect, that is, the directions of rotation and the pitches of the two helical lines are the same.

[0058] In some embodiments, as shown in Figure 5 The evaporator 4 further comprises a first conveying pipe 42 and a second conveying pipe 43, and the first conveying pipe 42 and the second conveying pipe 43 are both in communication with the container body 41. The container body 41 is sleeved on the ice-making cylinder 2 and is provided with a cavity for containing the cooling medium. One of the first conveying pipe 42 and the second conveying pipe 43 is used to input the cooling medium into the cavity of the container body 41, and the other is used to output the cooling medium from the cavity of the container body 41. Thus, in use, the cooling medium can be conveyed into one of the first conveying pipe 42 and the second conveying pipe 43, and the cooling medium transmits cold energy to the liquid to be frozen flowing along the inner wall surface of the ice-making cylinder 2 through the wall thickness of the ice-making cylinder 2, so as to achieve the purpose of freezing the liquid to be frozen.

[0059] In some embodiments, as shown in Figure 5As shown, the first delivery pipe 42 is configured to deliver cooling medium into the container body 41, the second delivery pipe 43 is configured to deliver the cooling medium in the container body 41 to the outside, and the first delivery pipe 42 is closer to the ice outlet end 25 of the ice making cylinder 2 than the second delivery pipe 43. In this way, in use, the cooling medium needs to overcome the gravity and gradually deliver from the first delivery pipe 42 to the second delivery pipe 43. Compared with the mode that the cooling medium is delivered from the second delivery pipe 43 and then delivered from the first delivery pipe 42, the cooling medium is prevented from flowing directly to the first delivery pipe 42 under the action of gravity, which is beneficial to prolong the time for the cooling medium to stay in the container body 41 and enhance the refrigeration effect.

[0060] The inventor of the present application finds that the relative position between the spiral groove 23 and the spiral channel 401 also affects the ice freezing result of the liquid to be frozen in the spiral groove 23. This is because, in the axial direction of the ice making cylinder 2 (i.e. the first direction X shown in the figures) Figure 7 When the first intersection line 233 of the spiral groove 23 is located above or below the position of the spiral channel 401 in the first direction X, the cooling capacity transferred from the spiral channel 401 to the spiral groove 23 is uneven, and the ice freezing efficiency of the liquid to be frozen in the spiral groove 23 is different.

[0061] Therefore, the inventor of the present application designs the relative position between the spiral groove 23 and the spiral channel 401 to improve the ice freezing efficiency of the liquid to be frozen in the spiral groove 23. Specifically, as shown in the figures, Figures 6-7 The flow guide piece 44 includes a first surface 441 and a second surface 442 arranged opposite to each other in the first direction X. The perpendicular distance between the first intersection line 233 and the first surface 441 in the first direction X is d1, and the perpendicular distance between the first intersection line 233 and the second surface 442 in the first direction X is d2. It is satisfied that d1=d2, d1>0, and d2>0. In other words, the first intersection line 233 of the spiral groove 23 is located at the middle position of the spiral channel 401, so that the liquid to be frozen in the spiral channel 401 can uniformly receive the cooling capacity transferred by the cooling medium and freeze.

[0062] In some embodiments, please refer to Figure 7, the diameter of the ice extruding hole 51 at the end close to the ice making cavity 21 is C1, and the diameter of the ice extruding hole 51 at the end away from the ice making cavity 21 is C2, and C1 > C2, the ice extruding hole 51 is used to extrude the crushed ice transported along the axis of the ice making cylinder 2 to the ice outlet end 25, so that the crushed ice is extruded by the ice extruding hole 51 and the screw 3 to form a predetermined shape and then sent out of the ice making cylinder 2. Specifically, when the crushed ice enters the ice extruding hole 51 from the end close to the ice making cavity 21, the crushed ice is gradually extruded into a predetermined shape in the ice extruding hole 51 due to the decreasing diameter of the ice extruding hole 51, and is gradually pushed out of the ice extruding hole 51 by the blade surface of the spiral scraper 32.

[0063] The shape of the ice extruding hole 51 can be set as needed, for example, it can be a horn shape, a circular truncated cone shape, or other shapes. The number of ice extruding holes 51 is two, three, four or more, which can be set as needed, and the plurality of ice extruding holes 51 are arranged in a ring shape on the bottom cover 5.

[0064] In some embodiments, as shown in Figure 4 , the bottom cover 5 is also provided with a plug-in port 52 communicating with the ice making cavity 21, the plug-in port 52 is used to be plugged and installed at the end of the screw 3 away from the mounting port 22, so that the plug-in port 52 and the mounting port 22 together constrain the screw 3 in the ice making cylinder 2, wherein the center line of the plug-in port 52 is on the same line as the center line of the mounting port 22, so that the axis of the ice making cylinder 2 coincides with the axis of the screw 3, ensuring that the screw 3 is coaxially arranged with the ice making cylinder 2. In this embodiment, the plug-in port 52 is arranged at the center of the plurality of ice extruding holes 51, that is, the plurality of ice extruding holes 51 are arranged in a ring around the plug-in port 52.

[0065] In some embodiments, as shown in Figure 2 , the ice making cylinder 2 further comprises a sealing assembly 6, the sealing assembly 6 is arranged at one end of the screw 3 and close to the mounting port 22, and the sealing assembly 6 is used to seal the connection between the screw 3 and the ice making cylinder 2, to avoid the leakage of the liquid to be frozen from the gap between the screw 3 and the mounting port 22 to the outside of the ice making cavity 21 during the transportation of the ice making device 1, and also to avoid the dust from the outside entering the ice making cavity 21. In this embodiment, the sealing assembly 6 comprises a first sealing plug 61, a second sealing plug 62 and an elastic member 63, the two ends of the elastic member 63 abut against the first sealing plug 61 and the second sealing plug 62 respectively, the first sealing plug 61 abuts against the protrusion arranged on the rod body 31, and the second sealing plug 62 abuts against the mounting port 22, under the elastic abutting action of the elastic member 63, the second sealing plug 62 can fill the gap between the rod body 31 and the ice making cylinder 2 at the mounting port 22, to achieve the purpose of sealing.

[0066] Further, as shown in Figure 2As shown, the sealing assembly 6 further comprises a first sealing pressing piece 64 and a second sealing pressing piece 65, the first sealing pressing piece 64 is annularly arranged on the first sealing plug 61, the second sealing pressing piece 65 is annularly arranged on the second sealing plug 62, and the two ends of the elastic member 63 abut against the first sealing pressing piece 64 and the second sealing pressing piece 65 respectively, so that the first sealing plug 61 and the second sealing plug 62 are uniformly pressed under the action of the first sealing pressing piece 64 and the second sealing pressing piece 65, and the sealing performance is not affected by uneven pressure on the first sealing plug 61 and the second sealing plug 62.

[0067] In some embodiments, as shown in Figure 2 As shown, the ice making device 1 further comprises a liquid supply tank 7, the liquid supply tank 7 is sleeved on the ice making cylinder 2, the liquid supply tank 7 is provided with a liquid inlet 701, and the liquid inlet 701 is in communication with the liquid inlet 24. In this way, since the liquid supply tank 7 surrounds the plurality of liquid inlets 24, the liquid to be frozen can supply liquid to the plurality of liquid inlets 24 after entering the liquid supply tank 7 through one liquid inlet 701.

[0068] In some embodiments, as shown in Figure 2 As shown, the distance between the liquid inlet 701 and the ice outlet end 25 of the ice making cylinder 2 is less than the distance between the liquid inlet 24 and the ice outlet end 25 of the ice making cylinder 2. In other words, the ground clearance of the liquid inlet 24 is higher than that of the liquid inlet 701. In this way, when the liquid to be frozen is introduced into the liquid supply tank 7, the gas bubbles floating on the surface can be squeezed into the ice making cylinder 2 through the liquid inlet 24 as the liquid level rises, reducing the risk of blockage of the liquid inlet 24. It should be noted that the distance between the liquid inlet 701 and the ice outlet end 25 of the ice making cylinder 2 refers to the distance between the center axis of the liquid inlet 701 and the ice outlet end 25 of the ice making cylinder 2, and similarly, the distance between the liquid inlet 24 and the ice outlet end 25 of the ice making cylinder 2 refers to the distance between the center axis of the liquid inlet 24 and the ice outlet end 25 of the ice making cylinder 2.

[0069] As shown in Figure 8 As shown, another embodiment of the ice making system 100 provided by the present application comprises the ice making device 1 in the above embodiments. The ice making system 100 further comprises a liquid supply assembly 10 connected with the liquid supply tank 7 of the ice making device 1, and the liquid supply assembly 10 is used for supplying the liquid to be frozen to the liquid supply tank 7.

[0070] In some embodiments, the liquid supply assembly 10 includes a water tank 11, a switching valve 12, and a pipe 13. The inlet end of the switching valve 12 is connected to the water tank 11, the outlet end of the switching valve 12 is connected to one end of the pipe 13, and the other end of the pipe 13 is connected to the inlet 701. Thus, when the switching valve 12 is opened, the liquid stored in the water tank 11 is transported along the pipe 13 to the inlet 701 of the liquid supply tank 7, and then enters the ice-making chamber 21 through the inlet 24. It is understood that, in use, the water tank 11 can be installed at a position higher than the liquid supply tank 7, so that the liquid in the water tank 11 can enter the liquid supply tank 7 along the pipe 13 under the action of gravity, and then enter the ice-making chamber 21 through the inlet 24.

[0071] In some embodiments, the ice-making system 100 further includes a drive mechanism 20, which is mounted on the ice-making cylinder 2 and connected to the screw 3. The drive mechanism 20 is used to drive the screw 3 to rotate. In this embodiment, the drive mechanism 20 includes a drive motor 20a and a connecting block 20b. The drive motor 20a is mounted on the connecting block 20b, and the connecting block 20b is connected to the ice-making cylinder 2. This achieves a relatively fixed position between the drive motor 20a and the ice-making cylinder 2, ensuring that the drive motor 20a stably drives the screw 3.

[0072] like Figure 9 As shown, another embodiment of this application provides an ice maker 200, which includes the ice-making system 100 and the housing 300 in the above embodiment, with the ice-making system 100 disposed inside the housing 300.
