Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic cross-sectional view of an embodiment of a squeeze container of the present application.

An embodiment of the present application discloses an extrusion barrel 100. The extrusion barrel 100 includes an extrusion section 110. The inner walls of the extrusion section 110 enclose an extrusion chamber 111. The pressing section 110 has an ice inlet 112 and an ice outlet 113 communicating with the pressing chamber 111. The ice inlet 112 is used for feeding ice sand, and the ice outlet 113 is used for extruding ice cubes. The cross-sectional area of the pressing chamber 111 gradually decreases from the ice inlet 112 to the ice outlet 113. When the ice sand continuously enters the extrusion cavity 111 from the ice inlet 112, as the cross section area of the extrusion cavity 111 gradually decreases from the ice inlet 112 to the ice outlet 113, the ice sand is gradually compacted in the process of being pushed forward and conveyed by the pushing force of the ice sand at the back in the extrusion cavity 111; and because the inner walls of the extrusion section 110 are closed to form the extrusion cavity 111, the ice and sand in the extrusion cavity 111 are uniformly stressed in all directions, the ice and sand can form ice cubes with higher hardness under the uniform stress, and the ice cubes are extruded from the ice outlet 113. The inner walls of the extrusion section 110 are closed to form the extrusion cavity 111, and the ice sand can be gradually compacted when passing through the extrusion cavity 111, so that the formed ice cubes are high in hardness and high in forming speed.

It should be noted that, during the process of pushing the ice and sand in the extrusion cavity 111, the ice and sand have friction with the peripheral wall of the extrusion cavity 111, in some embodiments, the inner wall of the extrusion section 110 is enclosed to form an extrusion cavity 111, the pushing force required for pushing the ice and sand forward is smaller, and under the condition of a certain driving force, the ice cake forming speed of the extrusion barrel 100 of the present application is fast; when the amount of ice and sand entering is constant, the ice cubes extruded by the extrusion barrel 100 of the present application have high hardness. Referring to fig. 2, fig. 2 is a schematic cross-sectional view of another embodiment of the extrusion barrel of the present application. In other embodiments, a partition 114 may be further disposed inside the extrusion chamber 111, where the partition 114 is disposed along the direction from the ice inlet 112 to the ice outlet 113 to divide the extrusion chamber 111 into a plurality of sub-extrusion chambers 1111, and the pushing force required for forward pushing of the ice in the plurality of sub-extrusion chambers 1111 is correspondingly increased, the amount of ice in each sub-extrusion chamber 1111 is reduced, and the hardness and speed of ice formation may be affected. The partition 114 may be provided according to actual circumstances.

In some embodiments, the length of the extruded section 110 is 90-100mm. Specifically, the length of the extruded section 110 is 90mm, 93mm, 95mm, 97mm, 100mm, or the like. The length of the extrusion section 110 should not be too short to ensure that the smoothie is extruded into ice cubes of sufficient hardness. The length of the extrusion section 110 cannot be too long to avoid excessive thrust required to push the smoothie into the extrusion chamber 111 and excessive length of the extrusion barrel 100, which would occupy too much space. The length of the extruding section 110 is within the above range to ensure that the extruding cylinder 100 is reasonable in length, and ice cubes can be extruded into ice cubes with sufficient hardness through the extruding cylinder 100, so that the ice cube forming speed is high.

In some embodiments, the ice inlet 112 is circular in cross-section. The ice inlet 112 is used for feeding ice and sand, so the ice inlet 112 is used for communicating with the ice making assembly 210 (see fig. 3), the ice making assembly 210 generally adopts the ice making screw 212 to make ice, and the circular ice inlet 112 is beneficial to communicating with the ice making assembly 210, so that the ice and sand can conveniently enter the ice making assembly 210 through the ice inlet 112. Wherein the diameter of the cross section of the ice inlet 112 is 25-30mm. Specifically, the cross-section of the ice inlet 112 has a diameter of 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm.

Further, the cross section of the ice outlet 113 is square. The side length of the cross section of the ice outlet 113 is 15-20mm. The cross-sectional area of the ice outlet 113 is smaller than that of the ice inlet 112, and the extrusion chamber 111 with a gradually smaller cross-sectional area can extrude the passing ice into ice cubes. In this embodiment, the cross section of the ice outlet 113 is square. The cross-section of the extrusion barrel 100 gradually transitions from a circular shape to a positive direction, and the cross-sectional area gradually decreases. The square ice cubes conform to the daily use habit of the user, and in other embodiments, the cross section of the ice outlet 113 can be round, triangular, rectangular, etc. Specifically, the side length of the cross section of the square ice outlet 113 is 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, or the like. When the sizes of the ice inlet 112 and the ice outlet 113 are designed, the square diagonal line of the cross section of the ice outlet 113 can be smaller than the diameter of the cross section of the ice inlet 112, so that the periphery of the ice is extruded by the inner wall of the extrusion cavity 111 in the process that the extrusion cavity 111 is pushed forward by the pushing force from the ice inlet 112 to the ice outlet 113, and the ice can be rapidly formed into ice cubes with higher hardness.

In some embodiments, the extruder barrel 100 further comprises a curing section 120. The curing section 120 is connected to the ice outlet 113 side of the pressing section 110. The curing section 120 is internally provided with a curing cavity 121, and the curing section 120 is hollow. The curing chamber 121 communicates with the pressing chamber 111 such that ice cubes within the pressing chamber 111 are output. The cross section of the curing chamber 121 is the same as that of the ice outlet 113. By arranging the curing section 120 at the ice outlet 113, the cross section of the curing cavity 121 inside the curing section 120 is the same as that of the ice outlet 113, and the formed ice cubes are supported and restrained in the curing cavity 121 and are further cured, so that the ice cubes are prevented from being broken due to the fact that the ice cubes are directly extruded from the ice outlet 113 and then are lost in restraint. In addition, the ice outlet 113 of the extruder barrel 100 is generally provided with an ice-cutting assembly 230 (see fig. 2) for breaking ice cubes into small ice cubes, and by providing the curing section 120, the formed ice cubes are received and supported by the curing chamber 121, avoiding breakage of ice cubes from the ice outlet 113 when the ice-cutting assembly 230 cuts off the ice cubes at the ice outlet 113.

Wherein the length of the curing section 120 is 8-15mm. Specifically, the length of the curing section 120 may be 8mm, 10mm, 11mm, 15mm, or the like.

Wherein the curing section 120 may be interconnected or integrally formed with the pressing section 110.

To facilitate stable passage of the smoothie into the extrusion chamber 111 from within the ice inlet 112, the extrusion barrel 100 further includes a connecting section 130. The connection section 130 is connected to one side of the ice inlet 112 of the compression section 110. The connecting section 130 is internally provided with a connecting cavity 131, and the connecting section 130 is hollow. The connection chamber 131 communicates with the pressing chamber 111. The connection section 130 is for connection with the ice making assembly 210 such that the smoothie of the ice making assembly 210 is transferred to the pressing chamber 111. Through the connection section 130 and the ice making assembly 210, the extrusion barrel 100 can be stably connected with the ice making assembly 210, the ice inlet 112 can be stably communicated with the ice making assembly 210, and the ice sand prepared by the ice making assembly 210 can continuously enter the extrusion cavity 111 from the ice inlet 112.

Wherein the length of the connection section 130 is 15-20mm. Specifically, the length of the connection section 130 may be 15mm, 17.5mm, 20mm, or the like.

Wherein the connection section 130 may be interconnected with the pressing section 110 or integrally formed therewith.

Specifically, the connection section 130 may be threadedly coupled with the ice making assembly 210. Wherein the extrusion barrel 100 may be made of aluminum alloy or other metal materials.

After the ice making is completed, there may be residual ice in the container 100 to block the ice outlet 113 of the container 100, thereby affecting the next ice making. In some embodiments, the extruder barrel 100 further comprises a heating wire. The heating wire can heat the extrusion barrel 100, so that residual ice in the extrusion barrel 100 is melted, and the phenomenon that the residual ice blocks the outlet of the extrusion barrel 100 is avoided.

With continued reference to fig. 3 and 4, fig. 3 is a schematic overall structure of an embodiment of an ice making apparatus of the present application; fig. 4 is a schematic cross-sectional structure of an embodiment of the ice making apparatus of the present application.

Yet another embodiment of the present application provides an ice making device 200. The ice-making device 200 includes an ice-making assembly 210, a heat exchange assembly 220, and an extrusion barrel 100. The output end of the ice making assembly 210 communicates with the ice inlet 112 of the compression section 110. The heat exchange assembly 220 is thermally coupled to the ice making assembly 210 such that the heat exchange assembly 220 exchanges heat with the ice making assembly 210 to provide the ice making assembly 210 with the cooling capacity required for making ice.

The ice-making assembly 210 includes an ice-making cylinder 211, an ice-making screw 212, and a driving member 215. An ice making chamber 216 is formed inside the ice making cylinder 211. The ice making chamber 216 is for containing a liquid to be made ice and for condensing the liquid to be made ice into an ice film. The ice-making cylinder 211 is formed with an output end communicating with the ice-making chamber 216, and the output end communicates with the ice inlet 112. The ice cream can enter the squeeze tube 100 from within the ice-making tube 211 through the output and the ice inlet 112. The ice making screw 212 is rotatably disposed in the ice making chamber 216. The driving member 215 is connected to the ice making screw 212, and the driving member 215 drives the ice making screw 212 to rotate. The ice making screw 212 rotating within the ice making chamber 216 may collect and store the ice within the ice making chamber 216 in a trough, and during rotation, as more and more ice is collected, the ice stored in the trough is increasingly compacted during rotation of the ice making screw 212, ready for the next step of forming firm ice cubes. The ice making screw 212 may rotationally collect and rotationally push and convey the ice in the ice cavity in the direction of the output end, so as to push and convey the ice formed in the ice making cavity 216 into the extrusion cavity 111 of the extrusion barrel 100, and extrude the ice into ice cubes with high hardness through the extrusion barrel 100. The cartridge 100 of any of the embodiments described above is employed with the cartridge 100. The ice making device 200 of the present application has a high ice making speed, far beyond the industry level, and can realize continuous ice discharge.

The ice-making barrel 211 is further provided with a water inlet 213, and the water inlet 213 is arranged at one end of the ice-making barrel 211 far away from the output end. The ice making cylinder 211 is filled with liquid to be refrigerated through the water inlet 213, and the liquid to be refrigerated is condensed into ice after being refrigerated in the ice making cylinder 211.

Specifically, the working area length of the ice making cylinder 211 mated with the ice making screw 212 is 92mm.

With continued reference to fig. 5, fig. 5 is a schematic cross-sectional view of an ice making assembly and a heat exchanging assembly of an embodiment of an ice making apparatus of the present application, for illustrating a screw groove. In some embodiments, the heat exchange assembly 220 is sleeved outside the ice making cylinder 211 to be in sufficient contact with the ice making cylinder 211 and provide the cooling capacity required for ice making by the ice making cylinder 211. Since the heat exchange assembly 220 is sleeved outside the ice making cylinder 211, water in the ice making cylinder 211 contacts with the inner wall of the ice making cylinder 211, and the inner wall of the ice making cylinder 211 forms an ice film. The ice film is positioned in front of the ice making screw 212 and the ice making cylinder 211, the driving piece 215 drives the ice making screw 212 to rotate, the ice making screw 212 scrapes off the ice film on the inner wall of the ice making cylinder 211, stores the ice film in a screw groove, and rotates, pushes and conveys the ice film in the direction of an output end so as to push and convey the ice sand formed in the ice making cavity 216 to the extrusion cylinder 100.

In some embodiments, heat exchange assembly 220 includes a heat exchange cartridge 221 and a spacer plate 222. The heat exchange tube 221 is disposed around the outside of the ice making tube 211. The heat exchange tube 221 and the ice making tube 211 are enclosed to form a heat exchange cavity for the heat exchange medium to pass through. The heat exchange tube 221 is provided with a liquid inlet 224 and a liquid outlet 225 communicating with the heat exchange chamber. The liquid inlet 224 and the liquid outlet 225 are generally positioned at two opposite ends of the heat exchange cavity. The partition plates 222 are disposed in the heat exchange cavity at intervals along the direction from the liquid inlet 224 to the liquid outlet 225. The dividing plate 222 divides the heat exchange chamber into a plurality of sub heat exchange chambers 223. The partition plate 222 is provided with a flow hole, and adjacent sub heat exchange chambers 223 are in flow communication with each other through the flow hole. The heat exchange medium flows into the heat exchange cavity from the liquid inlet 224, sequentially flows through the sub heat exchange cavities 223 through the flow holes, finally flows out through the liquid outlet 225, and only flows out through the sub flow holes through the partition plate 222, so that the flow path of the heat exchange medium in the heat exchange cavity is increased, the heat exchange cavity can fully exchange heat with the ice making cylinder 211, and the heat exchange efficiency is improved. Specifically, the sub-flow holes of the adjacent partition plates 222 are staggered, so that the flow path of the heat exchange medium can be further increased, and the heat exchange efficiency is fully improved. Further, the volumes of the plurality of sub heat exchange cavities 223 are gradually increased from the liquid inlet 224 to the liquid outlet 225, which is beneficial to the rapid flow of the heat exchange medium in the heat exchange cavities and improves the heat exchange efficiency.

Wherein, the length of the heat exchanging tube 221 in the length direction of the ice making tube 211 is 42-45.4mm. Specifically, the heat exchange tube 221 has a length of 42mm, 43mm, 45mm, 45.4mm, or the like. The heat exchanging tube 221 has a suitable length range, and can provide a suitable cooling capacity and a suitable cooling range for the ice making tube 211.

After the ice making process is finished, residual ice may exist in the ice making barrel 211 and the extrusion barrel 100, so that the next ice making process is affected, in some embodiments, the heat exchange assembly 220 can switch the flow direction of the refrigerant, so that the heat exchange medium with higher temperature flows into the heat exchange cavity, the whole refrigerating device is heated, and heat is transferred to the ice making barrel 211 and the extrusion barrel 100, so that the residual ice in the ice making barrel 211 and the extrusion barrel 100 is melted, and the influence of the blocking of the residual ice on the next ice making process is avoided.

Specifically, the ice making device 200 includes a mounting base 201, and a driving member 215 is mounted on the mounting base 201.

In some embodiments, the ice-making device 200 is in use, the angle β between the axis direction of the ice-making cylinder 211 and the horizontal direction is greater than 0 ° and less than or equal to 5 °, and the lowest point of the output end is higher than the lowest point of the end of the ice-making cylinder 211 that is remote from the output end. Specifically, the angle β between the axial direction of the ice-making cylinder 211 and the horizontal direction is 2 °,4 °, or 5 °. By placing the ice-making cartridge 211 laterally, the longitudinal space of the ice-making device 200 can be saved, and the ice-making device is suitable for more application scenes. For example, when the ice making device 200 is provided in a refrigerating apparatus such as a refrigerator, the ice making device 200 is placed laterally to be more adapted to the internal structure of the refrigerator. In other embodiments, when the refrigeration device is in use, the axis direction of the ice-making cylinder 211 is located in a vertical direction or in a direction having a predetermined inclination angle with respect to the vertical direction, and the refrigeration device is disposed vertically as a whole.

Further, the ice making device 200 further includes a water level detecting member 240, and the water level detecting member 240 is disposed in the pressing section 110. When the included angle β between the axis direction of the ice making cylinder 211 and the horizontal direction is greater than 0 ° and less than or equal to 5 °, the water level detecting member 240 is configured to output a signal when the water level reaches the lowest point of the ice outlet 113 of the pressing section 110. In fig. 4, the indication line X is the highest water level line position, and when the water level in the ice making device 200 reaches the highest water level line X, that is, when the water level reaches the lowest point of the ice outlet 113, the liquid to be cooled contained in the ice making cylinder 211 reaches the maximum amount, which is beneficial to condensation of more ice films on the inner wall of the ice making cylinder 211, and at this time, the liquid to be cooled is not easy to leak out from the ice outlet 113 directly. When the axial direction of the ice making cylinder 211 is located in the vertical direction, the water level detecting member 240 may be used to signal when the water level reaches a first position within the ice making cylinder 211, the first position being a position of the inner wall of the ice making cylinder 211 corresponding to the highest point of the heat exchanging cylinder 221. The heat exchange efficiency of the liquid to be cooled below the first position in the heat exchange assembly 220 is high.

With continued reference to fig. 6 and 7, fig. 6 is a schematic cross-sectional view of an ice-making assembly and a heat-exchanging assembly of an embodiment of an ice-making device of the present application, for illustrating the cooperation of an ice-making screw and an ice-making cartridge; fig. 7 is an enlarged view of a portion a in fig. 6. In some embodiments, the clearance between the screw teeth of the ice-making screw 212 and the inner wall of the ice-making cylinder 211 is 0.2-0.4mm. Specifically, the clearance between the screw teeth of the ice making screw 212 and the inner wall of the ice making cylinder 211 is 0.2mm, 0.27mm, 0.32mm, 0.4mm, or the like. The gap between the screw teeth of the ice-making screw 212 and the inner wall of the ice-making cylinder 211 is too small, and the screw teeth are easy to abrade the inner wall of the ice-making cylinder 211; the gap between the screw teeth of the ice making screw 212 and the inner wall of the ice making cylinder 211 is too large, the condensed ice film between the screw teeth and the ice making cylinder 211 is too thick, the condensed ice film and the inner wall of the ice making cylinder 211 are too tight, the screw teeth and the ice film are easy to slip, and the screw teeth are not easy to push and break the ice film. The clearance between the screw teeth and the inner wall of the ice making barrel 211 is in the above range, the ice making screw 212 is not easy to abrade the ice making barrel 211, and the ice film is easy to be crushed and collected, so that the ice making efficiency is improved.

In order to properly increase the friction of the ice film with the inner wall of the ice making cylinder 211 and with the ice making screw 212, in some embodiments, the inner wall of the ice making cylinder 211 is provided with a screw groove 214. The thread groove 214 increases the adhesive force between the ice film and the ice making cylinder 211, so that the ice film and the inner wall of the ice making cylinder 211 are prevented from slipping when the ice making screw 212 rotates, and the ice making screw 212 is not easy to break the ice film into ice. By providing the thread groove 214, the friction force between the ice film and the inner wall of the ice making barrel 211 and the friction force between the ice film and the ice making screw 212 can be properly increased, so that the ice film can be effectively converted into ice sand to be stored in the thread groove of the ice making screw 212 in the movement process, and the ice making efficiency of the ice making assembly 210 is improved.

The screw thread direction of the screw thread groove 214 on the inner wall of the ice making cylinder 211 is the same as the screw thread direction of the ice making screw 212, and at this time, the screw thread groove 214 can better increase the friction force between the ice film and the inner wall of the ice making cylinder 211 and between the ice film and the ice making screw 212. For example, the threads of the thread groove 214 are in a right-hand direction, as are the threads of the ice making screw 212. The threads of the thread groove 214 are left-handed, as are the threads of the ice screw 212.

With continued reference to fig. 8, fig. 8 is a schematic structural view of an ice making screw according to an embodiment of the ice making device of the present application. Wherein the depth of the thread groove 214 is 0.3-0.5mm. Specifically, the depth of the thread groove 214 is 0.3mm, 0.4mm, 0.5mm, or the like. The thread groove 214 is too shallow, the ice film and the inner wall of the ice making cylinder 211 are easy to slip, and the effect of increasing the friction force between the ice film and the inner wall of the ice making cylinder 211 and between the ice film and the ice making screw 212 can not be achieved; the screw groove 214 is too deep, so that the friction force between the ice film and the ice making cylinder 211 is too large, and the ice making screw 212 is difficult to break the ice film into ice. The screw groove 214 has a depth within the above range, and thus can provide a good friction increasing effect, and improve ice making efficiency of the ice making assembly 210.

Wherein the pitch of the thread groove 214 is twice the thread pitch of the ice making screw 212. The excessive pitch of the thread groove 214 has limited effect on increasing friction force between the ice film and the inner wall of the ice making cylinder 211 and between the ice film and the ice making screw 212; the thread pitch of the thread groove 214 is too small, the friction force between the ice film and the ice making cylinder 211 is too large, and the ice making screw 212 is difficult to break the ice film into ice.

Wherein the screw depth a of the ice making screw 212 is 5-6.4mm. Specifically, the screw groove depth a of the ice making screw 212 is 5mm, 5.4mm, 5.9mm, 6.2mm, 6.4mm, or the like. The screw depth a is too shallow, less smoothie can be collected, and the amount of compaction of the smoothie during the rotary pushing of the ice making screw 212 is insufficient, so that a longer extruder barrel 100 is required to extrude the smoothie into ice cubes; the depth a of the screw groove is too deep, the collectable ice is too much, the ice is extruded more firmly in the process of rotating and pushing the ice making screw 212, the hardness of the ice and the formed ice cubes is too high after the ice enters the extrusion barrel 100, the friction force between the ice and the extrusion barrel 100 is large, and the ice making screw 212 is driven to rotate and push by the driving piece 215 with higher output power. The screw depth a of the ice making screw 212 is preferably within the above range, and the ice making device 200 is high in ice making efficiency and high in ice hardness.

Wherein the pitch b of the ice making screw 212 is 10-11mm. Specifically, the pitch b of the ice making screw 212 is too large, more ice and sand can be accommodated between adjacent threads, the friction force is large, and the driving piece 215 with higher output power is required to drive the ice making screw 212 to rotate and push; the pitch b of the ice making screw 212 is too small, the receivable ice sand between adjacent screw teeth is small, and the degree of compaction of the ice sand during the rotary pushing of the ice making screw 212 is insufficient, so that a longer extruder barrel 100 is required to extrude the ice sand into ice cubes. The pitch b of the ice making screw 212 is preferably in the above range, and the ice making device 200 has high ice making efficiency and high ice hardness.

Wherein the working length c of the ice making screw 212 (the length of the screw portion in the axial direction of the ice making screw 212) is 75-81mm. Specifically, the working length c of the ice making screw 212 is 75mm, 77mm, 79mm, 81mm, etc. The working length c of the ice making screw 212 is too long, and the ice sand stays too long in the ice making screw 212, so that the ice cubes are not easily extruded from the extruding cylinder 100 due to the high hardness. The working length c of the ice screw 212 is too short, and less ice may be collected by the ice screw 212, which is detrimental to the extrusion of ice within the extruder barrel 100. The working length c of the ice screw 212 is preferably in the above range, and the ice making device 200 has high ice making efficiency and high ice hardness.

Wherein the lead angle d of ice screw 212 is 16. The thread lead angle d is too large, so that the ice films on the inner walls of the ice making screw 212 and the ice making cylinder 211 are easy to slip, and the collection of ice and sand is not facilitated; the screw angle d is too small, and the ice making screw 212 does not rotate in the direction of the squeeze container 100 to push the ice. The screw thread angle d of the ice making screw 212 is 16 degrees more reasonable, which is favorable for the collection and pushing of the ice and sand.

Wherein the main rod diameter e of the ice making screw 212 is 15mm. The thread diameter f is 25.2-25.4mm, e.g. 25.2mm, 25.1mm, 25.2mm etc. The length g of ice making screw 212 is 135-141mm, such as 135mm, 137mm, 139mm, 141mm, etc. The ice making screw 212 has the advantages that various parameters are matched with each other, the parameters of the extrusion barrel 100 can be matched for adjustment, ice cubes with the required size can be made, the ice making efficiency of the ice making device 200 is high, the ice making speed is high, and the hardness of the made ice cubes is high through the matching of the various parameters.

In some embodiments, the drive 215 includes a motor and a gear box. The output of the motor is coaxially fixed with the ice making screw 212. Since the ice cubes and the inner wall of the ice making cylinder 211 and the ice cubes and the inner wall of the extruding cylinder 100 have large friction force during the rotation of the ice making screw 212, the driving member 215 needs a sufficient torque output. Specifically, the rotation of ice screw 212 requires a torque of 30-40 nm, such as 30 nm, 32 nm, 35 nm, 38 nm, 40 nm, or the like. Accordingly, the maximum output of the driving member 215 needs to be greater than 40 nm. Additionally, in addition to the torque engagement, the rotational speed of the driving member 215 is engaged, and the rotational speed of the ice making screw 212 is 20-30r/min. Specifically, the rotational speed of ice making screw 212 is 20r/min, 23r/min, 26r/min, or 30r/min. The rotation speed of the ice making screw 212 within the above range can ensure stable output of ice cubes, satisfying the object of ice making speed.

In some embodiments, the extrusion barrel 100 includes an extrusion section 110. The inner walls of the extrusion section 110 enclose an extrusion chamber 111. The pressing section 110 has an ice inlet 112 and an ice outlet 113 communicating with the pressing chamber 111. The ice inlet 112 is used for feeding ice sand, and the ice outlet 113 is used for extruding ice cubes. The cross-sectional area of the pressing chamber 111 gradually decreases from the ice inlet 112 to the ice outlet 113. When the ice sand continuously enters the extrusion cavity 111 from the ice inlet 112, as the cross section area of the extrusion cavity 111 gradually decreases from the ice inlet 112 to the ice outlet 113, the ice sand is gradually compacted in the process of being pushed forward and conveyed by the pushing force of the ice sand at the back in the extrusion cavity 111; and because the inner walls of the extrusion section 110 are closed to form the extrusion cavity 111, the ice and sand in the extrusion cavity 111 are uniformly stressed in all directions, the ice and sand can form ice cubes with higher hardness under the uniform stress, and the ice cubes are extruded from the ice outlet 113. The inner walls of the extrusion section 110 are closed to form the extrusion cavity 111, and the ice sand can be gradually compacted when passing through the extrusion cavity 111, so that the formed ice cubes are high in hardness and high in forming speed.

In some embodiments, the extruder barrel 100 further comprises a curing section 120. The curing section 120 is connected to the ice outlet 113 side of the pressing section 110. The curing section 120 is internally provided with a curing cavity 121, and the curing section 120 is hollow. The curing chamber 121 communicates with the pressing chamber 111 such that ice cubes within the pressing chamber 111 are output. The cross section of the curing chamber 121 is the same as that of the ice outlet 113. By arranging the curing section 120 at the ice outlet 113, the cross section of the curing cavity 121 inside the curing section 120 is the same as that of the ice outlet 113, and the formed ice cubes are supported and restrained in the curing cavity 121 and are further cured, so that the ice cubes are prevented from being broken due to the fact that the ice cubes are directly extruded from the ice outlet 113 and then are lost in restraint. In addition, the ice outlet 113 of the extruder barrel 100 is generally provided with an ice cutting assembly 230 for breaking ice cubes into small ice cubes, and by providing the solidifying section 120, the formed ice cubes are received and supported by the solidifying cavity 121, thereby preventing the ice cubes from being broken from the ice outlet 113 when the ice cutting assembly 230 cuts off the ice cubes at the ice outlet 113.

In order to facilitate the stable entry of the smoothie into the extrusion chamber 111 from the ice inlet 112, the extrusion barrel 100 further comprises a connecting section 130, and the connecting section 130 is hollow. The connection section 130 is connected to one side of the ice inlet 112 of the compression section 110. The connection section 130 is formed therein with a connection chamber 131. The connection chamber 131 communicates with the pressing chamber 111. The connection section 130 is for connection with the ice making assembly 210 such that the smoothie of the ice making assembly 210 is transferred to the pressing chamber 111. Through the connection section 130 and the ice making assembly 210, the extrusion barrel 100 can be stably connected with the ice making assembly 210, the ice inlet 112 can be stably communicated with the ice making assembly 210, and the ice sand prepared by the ice making assembly 210 can continuously enter the extrusion cavity 111 from the ice inlet 112.

Specifically, the connection section 130 may be screw-coupled with the ice-making cylinder 211. The ice-making cylinder 211 may be made of high aluminum alloy or other metal materials.

In some embodiments, the ice making device 200 further includes an ice cutting assembly 230. The ice cutting assembly 230 includes a cutter 231 and a power member. The cutter 231 is movably disposed at the ice outlet 113 in an axial direction perpendicular to the extrusion container 100. The power piece is connected with the cutter 231, and the power piece drives the cutter 231 to move. After the ice column extends out of the ice making cylinder 211 for a certain length, the power member drives the cutter 231 to cut and break the ice column into ice cubes. The ice cubes may fall into the ice bank.

Wherein, the action of the power piece driving the cutter 231 to cut off the icicle can be controlled by a sensor. Specifically, it may be detected by a photoelectric sensor or a distance sensor that the icicle protrudes out of the extrusion container 100 to a predetermined length, and the power member drives the cutter 231 to cut and break the icicle into ice cubes. In other embodiments, the power member may be configured to drive the cutter 231 to perform an action at predetermined intervals, the length of the icicle extending out of the extrusion barrel 100 being approximately the length of a block of ice at predetermined intervals.

Yet another embodiment of the present application provides a refrigeration appliance. The refrigerating apparatus includes a body and an ice making device 200. The ice making device 200 may employ the refrigeration device of any of the embodiments described above. The refrigerating device is arranged in the body. The ice-making device 200 includes an ice-making assembly 210, a heat exchange assembly 220, and an extrusion barrel 100. The heat exchange assembly 220 is thermally coupled to the ice making assembly 210 such that the heat exchange assembly 220 exchanges heat with the ice making assembly 210 to provide the ice making assembly 210 with the cooling capacity required for making ice. The ice-making assembly 210 includes an ice-making cylinder 211, an ice-making screw 212, and a driving member 215. An ice making chamber 216 is formed inside the ice making cylinder 211. The ice making chamber 216 is for containing a liquid to be made ice and for condensing the liquid to be made ice into ice. The ice-making cylinder 211 is formed with an output end communicating with the ice-making chamber 216, and the output end communicates with the ice inlet 112. The ice cream can enter the squeeze tube 100 from within the ice-making tube 211 through the output and the ice inlet 112. The ice making screw 212 is rotatably disposed in the ice making chamber 216. The driving member 215 drives the ice making screw 212 to rotate. The ice making screw 212 rotating within the ice making chamber 216 may collect and store the ice within the ice making chamber 216 in a trough, and during rotation, as more and more ice is collected, the ice stored in the trough is increasingly compacted during rotation of the ice making screw 212, ready for the next step of forming firm ice cubes. The ice making screw 212 may rotationally collect and rotationally push and convey the ice in the ice cavity in the direction of the output end, so as to push and convey the ice formed in the ice making cavity 216 into the extrusion cavity 111 of the extrusion barrel 100, and extrude the ice into ice cubes with high hardness through the extrusion barrel 100.

The refrigerating device can be a refrigerating device such as a refrigerator, a freezer, an ice maker and the like which need to make ice.
