[0050] The present application provides a snow ice machine 100.

[0051] Please refer to Figure 1 、 Figure 3 and Figure 4 In an embodiment of the present application, the snow ice machine 100 comprises:

[0052] The base 1 is provided with a mounting portion 11 on one side;

[0053] The barrel 2 is provided with an opening on one side, and the opening is detachably mounted on the mounting portion 11. The barrel 2 is provided with an evaporator 3. The evaporator 3 comprises an inner barrel 31 and an outer barrel 32 which are nested, and a first end cover 33 which is provided on one end of the outer barrel 32 towards the base 1. The first end cover 33 comprises an annular sealing portion 331 and an extension portion 332 which is provided on the outer periphery of the annular sealing portion 331. The annular sealing portion 331 is connected with the inner barrel 31 and the outer barrel 32 respectively. The extension portion 332 is protruded on the side of the outer barrel 32, and the extension portion 332 is stacked on one side of the mounting portion 11 towards the inside of the barrel 2, and is mounted on the mounting portion 11.

[0054] Specifically, the base 1 is the main part of the ice cream machine 100, and the compressor 12, the expansion valve 15, the condenser 14 and the like are arranged in the base 1. The base 1 is provided with a mounting portion 11 on one side, and the material cylinder 2 and the evaporator 3 in the material cylinder 2 are mounted on the mounting portion 11. The opening side of the material cylinder 2 is detachably mounted on the mounting portion 11, so that the material cylinder 2 is easy to clean. The evaporator 3 is also mounted on the mounting portion 11. The evaporator 3, the compressor 12, the expansion valve 15 and the condenser 14 in the base 1 form a refrigeration circuit, so that the evaporator 3 can refrigerate the liquid food in the material cylinder 2. Therefore, the evaporator 3 is arranged in the material cylinder 2 and mounted on the mounting portion 11. The mounting portion 11 is provided with at least a through hole for the refrigeration circuit to pass through. Therefore, when the material cylinder 2 is mounted, not only the stability of the material cylinder 2 is ensured, but also the sealing between the evaporator 3 and the mounting portion 11 is ensured, so that the liquid food in the material cylinder 2 cannot flow into the base 1 through the gap between the material cylinder 2 and the mounting portion 11.

[0055] In the prior art, the evaporator is usually mounted by arranging a limiting ring. The limiting ring is sleeved on the evaporator, and the evaporator is preliminarily limited and fixed on the mounting portion. Then, the limiting ring is further pressed against the evaporator on the mounting portion, and the limiting ring is clamped on the mounting portion, so that the installation of the evaporator is completed. The limiting ring can also be used for sealingly mounting the material cylinder. This installation method needs to install the limiting ring and the evaporator respectively, and the installation is relatively complicated. In addition, the liquid food in the material cylinder may seep into the joint gap between the inner periphery of the limiting ring and the outer periphery of the evaporator, and then flow into the base. Therefore, a sealing member is usually arranged on the inner periphery of the limiting ring. However, the existence of the sealing member undoubtedly increases the sliding friction resistance between the limiting ring and the evaporator, increases the difficulty of sleeving the limiting ring, and further increases the difficulty and complexity of installing the evaporator. In addition, the liquid food in the material cylinder may seep into the joint gap between the evaporator and the limiting ring, causing a cleaning dead angle, increasing the cleaning difficulty of the material cylinder, and breeding bacteria or causing odor due to incomplete cleaning.

[0056] In the present solution, the evaporator 3 comprises an inner cylinder 31 and an outer cylinder 32 nested with each other, and a first end cover 33 arranged at one end of the outer cylinder 32 towards the base 1. The first end cover 33 comprises an annular sealing part 331 and an extension part 332 arranged at the outer periphery of the annular sealing part 331. The annular sealing part 331 is connected to the inner cylinder 31 and the outer cylinder 32 respectively. The extension part 332 is arranged at the periphery of the outer cylinder 32 and is arranged at the side of the mounting part 11 towards the inner barrel 2. The fastener is fastened to the extension part 332 through the mounting part 11. That is, the first end cover 33 can directly seal the space formed by the inner cylinder 31 and the outer cylinder 32, and fix the inner cylinder 31 and the outer cylinder 32, so as to ensure the stability of the structure of the evaporator 3. The first end cover 33 has the extension part 332 extending out of the periphery of the evaporator 3. The extension part 332 is fixed to the mounting part 11, so as to fix the evaporator 3. Thus, the mounting area of the evaporator 3 and the mounting part 11 is increased by directly extending the first end cover 33 of the evaporator 3, so as to ensure that the evaporator 3 can be stably mounted on the mounting part 11. The extension part 332 and the mounting part 11 are arranged in a stack, so as to facilitate the mounting of the evaporator 3 and the mounting part 11 and ensure the mounting stability of the evaporator 3 and the mounting part 11. In the actual assembly, the evaporator 3 can be assembled by only mounting the first end cover 33 on the mounting part 11, so as to simplify the assembly process of the evaporator 3 and reduce the number of parts, so as to reduce the dead angle and facilitate the daily cleaning of the user.

[0057] In the present embodiment, the annular sealing part 331 and the extension part 332 are integrally formed, so as to reduce the possibility of leakage of the liquid food in the inner barrel 2 through the joint gap between the two. Since the first end cover 33 is part of the evaporator 3 and the extension part 332 is arranged at the side of the mounting part 11 towards the inner barrel 2, the sealing between the evaporator 3 and the mounting part 11 is ensured by the abutting between the extension part 332 and the mounting part 11. Further, the second sealing ring 35 is arranged between the periphery of the extension part 332 and the periphery of the mounting part 11, so as to further improve the sealing effect between the extension part 332 and the mounting part 11.

[0058] In the present embodiment, the annular sealing part 331 and the extension part 332 are integrally formed, so as to reduce the possibility of leakage of the liquid food in the inner barrel 2 through the joint gap between the two. Since the first end cover 33 is part of the evaporator 3 and the extension part 332 is arranged at the side of the mounting part 11 towards the inner barrel 2, the sealing between the evaporator 3 and the mounting part 11 is ensured by the abutting between the extension part 332 and the mounting part 11. Further, the second sealing ring 35 is arranged between the periphery of the extension part 332 and the periphery of the mounting part 11, so as to further improve the sealing effect between the extension part 332 and the mounting part 11. Figure 4 and Figure 6The first end cover 33 is further provided with a first annular positioning groove 333, and one end of the outer cylinder 32 is inserted into the first annular positioning groove 333, so as to position the welding of the outer cylinder 32 and the first end cover 33, to ensure the welding stability of the outer cylinder 32 and the first end cover 33, and further reduce the possibility of the liquid food in the barrel 2 penetrating between the outer cylinder 32 and the first end cover 33. The inner cylinder 31 can also be welded to the first end cover 33. For example, the inner periphery of the first end cover 33 is provided with a first annular welding groove 334 on the side facing the inner cylinder 31, so as to increase the contact area of the first end cover 33 and the inner cylinder 31, and facilitate the welding of the first end cover 33 and the inner cylinder 31. In other embodiments, the first end cover 33 can also be integrally formed with the inner cylinder 31, that is, the first end cover 33 is formed by the outer punching of the one end of the inner cylinder 31.

[0059] In this embodiment, referring to Figure 1 、 Figure 4 、 Figure 5 and Figure 13 , the fastener is fastened to the extension 332 through the mounting portion 11. Optionally, the fastener does not penetrate the extension 332, so as to reduce the possibility of the liquid food in the barrel 2 leaking from the mounting portion of the fastener, and facilitate cleaning. Of course, the fastener can also penetrate the extension 332. Since the fastener is screwed to the extension 332, the fastener is not easy to leak. The fastener has a plurality of fasteners, and the plurality of fasteners are arranged at intervals along the circumference of the first end cover 33, so as to ensure the stable fixation of the first end cover 33 and the mounting portion 11. In other embodiments, the extension 332 can be clamped or bonded to the mounting portion 11.

[0060] In order to further facilitate the installation of the extension 332 and the barrel 2, in an embodiment, referring to Figure 1 、 Figure 4 、 Figure 5 and Figure 13 , the extension 332 has a positioning column 335, and the mounting portion 11 is correspondingly provided with a positioning groove 111. The positioning column 335 is inserted into the positioning groove 111, and the fastener is screwed to the positioning column 335 through the positioning groove 111. Specifically, through the insertion of the positioning column 335 and the positioning groove 111, the installation of the evaporator 3 can be further positioned, and the evaporator 3 can be preliminarily fixed, so as to facilitate the installation of the fastener. The presence of the positioning column 335 can also locally thicken the thickness of the extension 332, so as to increase the threaded connection area of the extension 332 and the fastener, and reduce the possibility of the fastener penetrating the extension 332. The positioning column 335 can be integrally formed on the extension 332, or can be welded or screwed to the extension 332.

[0061] Please refer to Figure 4 and Figure 10In the embodiment of the present application, the inner cylinder 31, the outer cylinder 32 and the annular sealing part 331 jointly enclose a heat exchange cavity 321 for refrigerant flow, and the evaporator 3 further comprises an inlet pipe 36 and an outlet pipe 37 which are in communication with the heat exchange cavity 321, the outlet pipe 37 is arranged close to the top of the heat exchange cavity 321 at the communication position with the heat exchange cavity 321, and the inlet pipe 36 is arranged close to the bottom of the heat exchange cavity 321 at the communication position with the heat exchange cavity 321. Specifically, the inner cylinder 31 is embedded in the inner side of the outer cylinder 32, and is arranged in a spaced manner to form the heat exchange cavity 321 between the inner cylinder 31 and the outer cylinder 32, the heat exchange cavity 321 is used to contain the refrigerant, and the refrigerant flows in the heat exchange cavity 321 and conducts the cold to the outside through the outer cylinder 32. Therefore, in the working process of the evaporator 3 in the present solution, the cold only needs to be transmitted to the liquid food through the outer cylinder 32, that is, the heat conduction can be realized through a single-layer structure, compared with the disc tube type evaporator in the prior art which needs to pass through a double-layer structure to realize the heat conduction (the cold generated by the structure of the disc tube type evaporator needs to pass through the evaporation pipe and then pass through the heat exchange cylinder to be conducted to the raw materials, which causes the heat resistance of the evaporator 3 to be large, which is not conducive to the cold conduction of the evaporator 3), therefore, the evaporator 3 in the present solution can reduce one heat conduction layer when transmitting the heat, thereby improving the heat exchange efficiency of the evaporator 3, and the refrigerant in the present solution fills the entire heat exchange cavity 321, therefore, there is no gap in the heat exchange cavity 321, compared with the evaporator 3 in the prior art (the contact area between the evaporation pipe and the heat exchange cylinder of the disc tube type evaporator is limited, and there is inevitably an air gap between them, which undoubtedly further increases the heat resistance of the evaporator 3), which can further reduce the heat resistance of the evaporator 3, thereby improving the heat exchange efficiency of the evaporator 3, and further improving the production efficiency of the ice slush machine 100. Preferably, the inner cylinder 31 and the outer cylinder 32 are coaxially arranged, thereby ensuring the uniformity of the thickness of the heat exchange cavity 321 and improving the heat exchange uniformity.

[0062] One end of the inlet pipe 36 is used to communicate with the expansion valve 15, and the other end is used to communicate with the heat exchange cavity 321, and the communication position of the inlet pipe 36 with the heat exchange cavity 321 is arranged close to the bottom of the heat exchange cavity 321; one end of the outlet pipe 37 is used to communicate with the compressor 12, and the other end is used to communicate with the heat exchange cavity 321, and the communication position of the outlet pipe 37 with the heat exchange cavity 321 is arranged close to the top of the heat exchange cavity 321, therefore, the height of the communication position of the inlet pipe 36 with the heat exchange cavity 321 is lower than the height of the communication position of the outlet pipe 37 with the heat exchange cavity 321, that is, the evaporator 3 in the present solution adopts the way of entering from the bottom and discharging from the top to introduce the refrigerant into the heat exchange cavity 321, thereby making the refrigerant flow upward under the influence of gravity during the introduction process, and then filling the entire cavity from the bottom to the top and then flowing out from the outlet pipe 37, thereby ensuring that the refrigerant flows more uniformly from the bottom of the evaporator 3 to the outlet pipe 37, thereby reducing the possibility of local uneven heat exchange of the evaporator 3 and improving the working performance of the ice slush machine 100.

[0063] It should be noted that in the embodiment, the evaporator 3 is horizontally installed on the slush machine 100, that is, the axial direction of the evaporator 3 is substantially parallel to the horizontal direction. The evaporator 3 has a horizontal cross section passing through the axial line of the evaporator 3. The communication part of the inlet pipe 36 and the heat exchange cavity 321 is arranged below the horizontal cross section, and the communication part of the outlet pipe 37 and the heat exchange cavity 321 is arranged above the horizontal cross section. Alternatively, the communication part of the outlet pipe 37 and the heat exchange cavity 321 is arranged at the top of the inner cylinder 31, that is, the connecting line of the communication part of the outlet pipe 37 and the heat exchange cavity 321 to the axial line of the evaporator 3 is arranged vertically to the horizontal cross section. The communication part of the inlet pipe 36 and the heat exchange cavity 321 is arranged at the bottom of the inner cylinder 31, that is, the connecting line of the communication part of the inlet pipe 36 and the heat exchange cavity 321 to the axial line of the evaporator 3 is arranged vertically to the horizontal cross section. Thus, the height difference between the communication part of the inlet pipe 36 and the heat exchange cavity 321 and the communication part of the outlet pipe 37 and the heat exchange cavity 321 can be ensured, and the refrigerant can be fully filled in the heat exchange cavity 321 before flowing out of the outlet pipe 37.

[0064] In other embodiments, the evaporator 3 can also be vertically installed on the slush machine 100, that is, the axial direction of the evaporator 3 is substantially parallel to the vertical direction. At this time, the communication part of the inlet pipe 36 and the heat exchange cavity 321 is arranged close to the bottom of the evaporator 3, that is, the communication part of the inlet pipe 36 and the heat exchange cavity 321 is arranged on the end surface of the lower end or on the axial side of the lower end of the evaporator 3. The communication part of the outlet pipe 37 and the heat exchange cavity 321 is arranged close to the top of the evaporator 3, that is, the communication part of the outlet pipe 37 and the heat exchange cavity 321 is arranged on the end surface of the upper end or on the axial side of the upper end of the evaporator 3.

[0065] Further, the inner side of the inner cylinder 31 is provided with a refrigerant inlet 311 and a refrigerant outlet 312 communicating with the heat exchange cavity 321. The refrigerant outlet 312 is arranged close to the top of the inner cylinder 31. The outlet pipe 37 is sequentially arranged in the mounting part 11, the first end cover 33 and the inner cylinder 31, and communicates with the refrigerant outlet 312. The refrigerant inlet 311 is arranged close to the bottom of the inner cylinder 31. The inlet pipe 36 is sequentially arranged in the mounting part 11, the first end cover 33 and the inner cylinder 31, and communicates with the refrigerant inlet 311. Specifically, the inlet pipe 36 and the outlet pipe 37 both extend into the evaporator 3 from the inner side of the inner cylinder 31 to connect the refrigerant inlet 311 and the refrigerant outlet 312 respectively. Thus, the idle space in the evaporator 3 can be used to place the inlet pipe 36 and the outlet pipe 37, and the connection of the inlet pipe 36 and the outlet pipe 37 with the heat exchange cavity 321 is facilitated. Further, the inlet pipe 36 includes a capillary tube section arranged on the inner side of the inner cylinder 31. That is, the inlet pipe 36 can also act as the expansion valve 15 in the refrigerant circuit of the slush machine 100. The capillary tube section is arranged on the inner side of the inner cylinder 31. On the one hand, the idle space on the inner side of the inner cylinder 31 is further utilized. On the other hand, the distance between the capillary tube section and the refrigerant inlet 311 is reduced, and the heat exchange efficiency is improved.

[0066] Further, the refrigerant outlet 312 and the refrigerant inlet 311 are arranged in axial staggered manner along the evaporator 3, so as to further increase the distance between the refrigerant inlet 311 and the refrigerant outlet 312, and reduce the possibility that the refrigerant entering the heat exchange cavity 321 through the refrigerant inlet 311 is directly discharged through the refrigerant outlet 312.

Therefore, the stirring structure 5 and the transmission shaft 62 are in transmission connection with the end of the evaporator 3 which is away from the mounting portion 11. Alternatively, referring to Figure 4 and Figure 7 , the stirring structure 5 is provided with a transmission block 51 at the end of the evaporator 3, the transmission block 51 is in transmission connection with the end of the transmission shaft 62 which is away from the driving motor 61, so that the driving motor 61 can stably drive the stirring structure 5 to rotate.

And the second end cover 38 is provided with a fixing protrusion 381 on the side facing the inner cylinder 31, and the fixing protrusion 381 has a mounting hole 382 penetrating the fixing protrusion 381 and the second end cover 38, the transmission shaft 62 is sequentially arranged in the guide sleeve 39 and the mounting hole 382, and is drivingly connected with the transmission block 51, thereby providing limiting support for the transmission shaft 62, reducing the possibility of eccentric rotation of the transmission shaft 62, and also ensuring coaxial rotation of the stirring structure 5 and the transmission shaft 62, thereby ensuring transmission stability.

[0073] In order to facilitate the installation of the guide sleeve 39, the fixing protrusion 381 comprises a large section 3811 and a small section 3812 connected together, the large section 3811 is connected to the second end cover 38, and the small section 3812 is arranged at one end of the large section 3811 away from the second end cover 38, and the large section 3811 and the small section 3812 form a stepped surface, the guide sleeve 39 is sleeved on the small section 3812 and abuts against the stepped surface, thereby positioning the installation of the guide sleeve 39.

In order to ensure the stable installation of the guide sleeve 39, the sleeving depth of the guide sleeve 39 and the small section 3812 is greater than or equal to 10mm, and the two are in interference or transition fit to ensure sealing, so that when the inner side of the inner cylinder 31 is filled with foaming liquid, the foaming liquid cannot overflow from the gap between the guide sleeve 39 and the small section 3812 during the expansion process due to its own fluidity, achieving the purpose of preventing bubble leakage.

[0074] In order to ensure the sealing of the mounting hole 382, in an embodiment, a sealing structure 383 is arranged on the inner periphery of one end of the fixing protrusion 381 facing the second end cover 38, the sealing structure 383 is sleeved on the transmission shaft 62, that is, the sealing structure 383 is arranged in the mounting hole 382 and on the side of the second end cover 38 facing the inside of the evaporator 3, and the transmission shaft 62 is rotatably arranged in the sealing structure 383, thereby ensuring the sealing of the mounting hole 382.

The mounting columns 52 abut against the outer periphery of the outer cylinder 32, so that when the stirring structure 5 is stirring, the mounting columns 52 can constantly rub against the outer periphery of the outer cylinder 32, thereby reducing the possibility of the liquid food being attached to the outer periphery of the outer cylinder 32, and facilitating the cleaning of the barrel 2. The stirring blades 53 are arranged around the plurality of mounting columns 52 and are arranged in a spiral shape, so as to improve the stirring efficiency and constantly send the liquid food to the discharge port at the end of the barrel 2 away from the mounting portion 11.

[0081] Further, referring to Figure 4, the axial direction of the evaporator 3 and the axial direction of the stirring structure 5 are both inclined downward away from the driving structure 6.
