[0020] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly. The connection described can be a direct connection or an indirect connection.

[0023] Please refer to Figures 1-3 As shown, the structure of an ice extrusion screw includes an ice extrusion screw device 1; the upper and lower ends of the ice extrusion screw device 1 are respectively detachably and fixedly connected with an ice outlet device 3 and a support seat 4; the ice outlet device 3 and the support seat 4 are detachably and fixedly connected with an evaporator 2; a spiral groove 15 is formed in the evaporator 2; a diversion groove 16 is formed in the ice extrusion screw device 1; the upper and lower ends of the spiral groove 15 are communicated and fixedly connected with a refrigerant outlet pipe 5 and a refrigerant inlet pipe 6 on the outer surface of the evaporator 2; the lower end of the evaporator 2 is communicated and fixedly connected with an ice-making water inlet pipe 7 to the ice extrusion screw device 1; during operation, pure water is injected through the ice-making water inlet pipe 7 by an external water pump, and the refrigerant outlet pipe 5 and the refrigerant inlet pipe 6 are connected to a refrigerant pump externally, so that the refrigerant is cooled and frozen into a mold in the spiral groove 15. Then, the ice extrusion screw device 1 rotates under external power, thereby pushing the ice upward, so that the ice is stressed when contacting the ice outlet device 3 during movement and is divided into ice cubes with sizes close to each other, so that the ice cubes can be continuously pushed out without rotating with the ice extrusion screw device 1 to complete ice outlet, solving the technical problems of ice accumulation and ice explosion in the existing ice extrusion screw during the ice extrusion process.

[0024] A sealing groove 12 is formed in the support seat 4; a sealing strip 13 is sleeved in the sealing groove 12; during operation, the support seat 4 and the evaporator 2 are in a sealed state through the sealing strip 13, so that the water melted from the ice cubes can be collected and wait for reuse, and thus will not flow everywhere under the action of gravity.

[0025] A plurality of fixed installation holes 10 are formed in the support seat 4; a plurality of weight reduction grooves 14 are formed in the support seat 4; during operation, the weight of the support seat 4 is further reduced without reducing the strength through the weight reduction grooves 14, and stable fixation in the ice maker can be achieved through the fixed installation holes 10 in cooperation with fasteners, thereby reducing resonance.

[0026] The evaporator 2 and the ice ejector 3 are both provided with first positioning and mounting holes 8; during operation, the evaporator 2 and the ice ejector 3 can be detachably and stably fixed together through the cooperation of the first positioning and mounting holes 8 and fasteners, thus facilitating disassembly and cleaning for long-term use.

[0027] The evaporator 2 and the support base 4 are both provided with second positioning and mounting holes 9; during operation, the evaporator 2 and the support base 4 can be detachably and stably fixed together through the cooperation of the second positioning and mounting holes 9 and fasteners, thus facilitating disassembly and cleaning for long-term use.

[0028] A driving device is fixedly connected to the lower end of the ice extrusion screw device 1; a sealing sleeve 11 is hermetically sleeved on the lower end of the ice extrusion screw device 1; the slope of the spiral groove 15 is between 17 and 22 degrees; during operation, the ice extrusion screw device 1 with a sealed lower end can be driven to rotate by the driving device, and the formed ice cubes are broken and extruded upward from the ice ejector 3; with the slope of the spiral groove 15 being between 17 and 22 degrees and the optimal angle being 20 degrees, when the spiral groove 15 pushes the ice cubes to move upward, the ice cubes are squeezed to both sides, and the ice moving upward will be close to the inner side surface of the evaporator 2, ensuring that the ice does not rotate simultaneously with the ice extrusion screw device 1, resulting in smooth ice ejection and solving the problem of unsmooth ice ejection of the existing ice extrusion screw.

[0029] With the above solution, when the utility model is in use, pure water is injected through the ice-making water inlet pipe 7 externally connected to a water pump, and the refrigerant outlet pipe 5 and the refrigerant inlet pipe 6 are externally connected to a refrigerant pump, so that the refrigerant is cooled and frozen into a mold in the spiral groove 15. Then, the ice extrusion screw 1 rotates under external power, thus pushing the ice cubes upward, causing the ice cubes to contact the ice ejector 3 during movement and being forced into ice cubes of similar size, enabling the ice cubes to be continuously pushed out without rotating with the ice extrusion screw 1 to complete ice ejection, solving the technical problems of ice accumulation and ice explosion during ice extrusion of the existing ice extrusion screw; through the sealing strip 13, the support base 4 and the evaporator 2 are in a sealed state, so that the water melted from the ice cubes can be collected and waiting to be reused again, and thus will not flow everywhere under the action of gravity; through the weight reduction groove 14, the weight of the support base 4 is further reduced without reducing its strength, and it can be stably fixed in the ice maker by means of the fixed mounting holes 10 in cooperation with fasteners, thereby reducing resonance; through the first positioning mounting holes 8 in cooperation with fasteners, the evaporator 2 and the ice ejector 3 can be detachably and stably fixed, thus facilitating disassembly and cleaning for long-term use; through the second positioning mounting holes 9 in cooperation with fasteners, the evaporator 2 and the support base 4 can be detachably and stably fixed, thus facilitating disassembly and cleaning for long-term use; through the driving device, the ice extrusion screw 1 with a sealed lower end can be driven to rotate, and the extruded and formed ice cubes are broken and extruded upward from the ice ejector 3; since the slope of the spiral groove 15 is between 17 and 22 degrees, and the optimal angle is 20 degrees, when the spiral groove 15 pushes the ice cubes upward, the ice cubes are squeezed to both sides, and the ice moving upward will be close to the inner side of the evaporator 2, ensuring that it will not rotate with the ice extrusion screw 1 at the same time and causing unsmooth ice ejection, solving the problem of unsmooth ice ejection of the existing ice extrusion screw.
