[0026] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments.

[0027] Please refer to Figures 1 to 3The evaporator 1 of the ice slurry machine comprises an outer cylinder 11, an inner cylinder 12, an inlet pipe 13, an outlet pipe 14, a heat insulation part 15 and a bottom plate 16. The outer cylinder 11 is cylindrical and made of metal material, has an outer ring wall 111 and a top wall 112, and has a containing space 113 in the center. The top wall 112 is provided with an upper through hole 114 in the center.

[0028] The inner cylinder 12 is approximately cylindrical, has a diameter smaller than that of the outer cylinder 11, and is coaxially arranged in the containing space 113 corresponding to the outer cylinder 11. The inner cylinder 12 has an inner ring wall 121 and a content chamber 122 in the center. The top end of the inner ring wall 121 is connected to the top wall 112 of the outer cylinder 11 by welding or other appropriate means, and an annular space 123 is formed between the inner cylinder 12 and the outer cylinder 11. The bottom of the inner ring wall 121 extends radially outward to form a lower ring wall 124. The lower ring wall 124 is connected to the bottom end of the outer ring wall 111 by welding or other appropriate means and can seal the annular space 123. The lower ring wall 124 is provided with an inlet hole 125 and an outlet hole 126 opposite the inlet hole 125. The inlet hole 125 and the outlet hole 126 are in communication with the annular space 123.

[0029] The inlet pipe 13 is axially arranged in the annular space 123 and is connected to the inlet hole 125 at the bottom. The inlet pipe 13 is provided with a plurality of air outlet holes 131. The inlet pipe 13 further comprises a guide piece 132 made of metal material and in the shape of an arc. The guide piece 132 is axially arranged in the annular space 123 and located on one side of the inlet pipe 13. The guide piece 132 is provided with a plurality of air permeable holes 133. The guide piece 132 has a gap 134 with the outer ring wall 111, and most of the area of the guide piece 132 does not adhere to the outer ring wall 111.

[0030] The outlet pipe 14 is arranged outside the lower ring wall 124 and is in communication with the outlet hole 126.

[0031] The heat insulation part 15 is made of plastic foam or other materials with good heat insulation properties and is arranged in the content chamber 122 of the inner cylinder 12. The heat insulation part 15 is provided with an axial hole 151 corresponding to the position of the upper through hole 114 of the outer cylinder 11.

[0032] The bottom plate 16 is arranged below the heat insulation part 15 and can seal the bottom of the content chamber 122. The bottom plate 16 is provided with a lower through hole 161 corresponding to the position of the axial hole 151.

[0033] Please refer to Figures 1 to 4 The ice slurry machine further comprises a container 2, a transmission device 3, a stirring device 4, a condenser 5 and a compressor 6. The container 2 can contain beverages (not shown in the figure) and is arranged outside the evaporator 1. One side of the container 2 is provided with a guide outlet 21.

[0034] The transmission device 3 has a motor 31, a rotating shaft 32 driven by the motor 31, and the rotating shaft 32 penetrates the lower through hole 161, the shaft hole 151, the upper through hole 114 of the evaporator 1 and the stirring device 4.

[0035] The stirring device 4 is arranged in the container 2, and the upper central part is connected with the rotating shaft 32, and the stirring blade 41 arranged at the outer edge of the evaporator 1 can push the beverage and scrape the position of the outer ring wall 111 of the evaporator 1.

[0036] One end of the connecting pipe (not shown in the figure) of the condenser 5 is connected with the inlet pipe 13 of the evaporator 1, and the other end of the connecting pipe (not shown in the figure) of the condenser 5 is connected with the compressor 6.

[0037] The connecting pipe (not shown in the figure) of the compressor 6 is connected with the outlet pipe 14, so that the compressor 6, the condenser 5 and the evaporator 1 form a cooling circuit, and the refrigerant 7 (such as Freon) is arranged in the circuit. Figure 5

[0038] Please refer to Figures 1 to 5 , the beverage (not shown in the figure) is placed in the container 2, and the condenser 5, the compressor 6 and the transmission device 3 are started. The compressor 6 compresses the refrigerant 7 into the condenser 5, and releases heat energy from the condenser 5. The refrigerant 7 output from the condenser 5 is input into the inlet pipe 13 of the evaporator 1 through the pipe pressure reduction, and the gasified refrigerant 7 is guided out of the outlet hole 131 into the annular space 123 of the evaporator 1, so that the evaporator 1 can cool the beverage outside the outer ring wall 111, and the part of the gasified refrigerant 7 guided out of the outlet hole 131 can cool the outer ring wall 111 at the position of one side of the guide blade 132 through the air hole 133. Therefore, the guide blade 132 can guide most of the gasified refrigerant 7 guided out of the outlet hole 131 to the position far away from the inlet pipe 13 in the annular space 123, and can avoid the gasified refrigerant 7 concentrated at the position of the inlet pipe 13 to have a more balanced refrigeration effect.

[0039] ​The refrigerant 7 vaporized in the annular space 123 can directly contact the outer ring wall 111 without being blocked, so that the beverage outside the outer ring wall 111 can be quickly cooled by heat absorption. The inner ring wall 121 of the inner cylinder 12 has the heat insulation piece 15 on the inner side, so that the heat absorption of the vaporized refrigerant 7 to the inner cylinder 12 is reduced, and the heat absorption efficiency of the outer cylinder 11 is reduced. Therefore, the refrigerant 7 vaporized in the present application can directly contact the outer ring wall 111 without being blocked, and the heat absorption of the outer ring wall 111 can greatly improve the cooling efficiency and energy saving effect of the evaporator 1, and the beverage can be quickly cooled. The stirring piece 41 of the stirring device 4 is scraped off the slush ice beverage on the outer ring wall 111, and the beverage can be discharged from the discharge port 21 of the container 2. The vaporized refrigerant 7 after heat absorption can form a cooling loop that can continuously cool the beverage by the evaporator 1 through the discharge hole 126 of the evaporator 1, the discharge pipe 14 and the pipe to the compressor 6.

[0040] Therefore, the evaporator of the present application can greatly improve the cooling efficiency of the slush machine, and the above-mentioned embodiments are examples of the present application, not limitations of the present application. Any equivalent changes made in accordance with the spirit of the present application shall also belong to the scope of the present application.
