Description

Technical Field

[0001] The utility model relates to the technical field of snow melting machines, in particular to an evaporator and a snow melting machine using the evaporator. Background Art

[0002] As people's living standards continue to improve, they need to pursue more refined and higher-quality food ingredients. A snow melt machine is a device that can make molten smoothies, and can provide users with a molten drink that is between a liquid drink and solid ice cubes. Existing snow melt machines are usually only suitable for commercial use due to the limitations of size and processing capacity. Existing snow melt machines are usually provided with a machine base, on which a storage chamber for storing liquid drinks is provided. The storage chamber is provided with an evaporator for cooling the drink and a stirring paddle for stirring the drink. The machine base is provided with a drive motor for driving the stirring paddle to rotate. The temperature of the drink stored in the storage chamber is gradually reduced to the freezing point by the evaporator, forming an ice-water mixture, and under the continuous stirring of the stirring paddle, a mixed snow melt is formed. However, people now expect to be able to make snow melt products conveniently by themselves in a home use environment.

[0003] To meet these requirements, existing snow melters simply reduce the size of each module. For example, the mixing drum, evaporator, and stirring paddle of the refrigeration component are proportionally compressed, thereby achieving a small-volume cooking process. However, proportionally reduced refrigeration components have the technical problem of poor cooling efficiency. In particular, if the evaporator is too small, the condensation channel located within the evaporator will not be able to be installed, or the distance between the condensation channels is too short, making it impossible to effectively achieve cooling. If sufficient condensation channels are installed, the volume of the evaporator will inevitably increase, which will also increase the overall volume of the refrigeration component. This makes it impossible to provide users with a truly compact evaporator and snow melter product that is easy to use and store, especially suitable for home use. Summary of the Invention

[0004] In view of the defects and shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an evaporator and snow melter using a high-efficiency method to solve the problems of large size and poor cooling efficiency of the existing evaporator, as well as the large size of the snow melter and poor cooling efficiency caused by the large size of the evaporator, and the waste of space and structure caused by the simple function of the snow melter.

[0005] In order to solve the above technical problems, the present application discloses an evaporator using a high-efficiency evaporator, which includes a cylinder and an evaporator bracket for fixing the cylinder, and the cylinder includes: an inner cylinder, including an inner cylinder wall that is annular and open at the front end, and an inner end wall that closes the rear end opening of the inner cylinder wall; an outer cylinder, including an outer cylinder wall that is annular and sleeved on the outside of the inner cylinder wall, and the outer cylinder wall and the front end of the inner cylinder wall are sealed and connected to form an internal space; a spiral condensation channel, located in the internal space; and a cylinder connecting the condensation inlet and condensation outlet of the spiral condensation channel; wherein, the spiral condensation channel is simultaneously in contact with the inner side wall of the outer cylinder wall and the outer side wall of the inner cylinder wall.

[0006] According to the present invention, the evaporator comprises an inner cylinder and an outer cylinder. The inner cylinder has an opening at the front end, and the inner end wall seals the rear end of the inner cylinder, forming an inner cylinder space within the inner cylinder. The outer cylinder is sleeved over the inner cylinder to form an inner space between the outer and inner cylinders. The spiral condensation channel of the evaporator for cooling is located within the inner space. Preferably, the spiral condensation channel is aligned with both the inner sidewall of the outward-facing wall and the outer sidewall of the inner cylinder. Thus, the outer surface of the outer cylinder and the inner surface of the inner cylinder simultaneously form cooling surfaces that can contact and cool food. Compared to prior art evaporators that only have the outer surface of the cylinder for cooling, the present invention not only retains the outer surface of the outer cylinder as a cooling surface, but also further adds the inner surface of the inner cylinder as a cooling surface. Thus, when the evaporator is located within the mixing drum of the snow melter, both the outer surface of the outer cylinder and the inner surface of the inner cylinder can cool the cooking food within the mixing drum, significantly improving the cooling efficiency of the snow melter. Moreover, since the outer cylinder is directly sleeved on the outside of the inner cylinder, the spiral condensation channel is clamped between the two, and the inner cylinder space that can accommodate and cool food ingredients is directly formed inside the inner cylinder, the evaporator does not occupy too much cooking space in the mixing cylinder, so that the mixing cylinder can achieve large-capacity processing in a sufficiently small space, thereby compressing the volume of the evaporator and the corresponding snow melting machine to achieve a small and efficient evaporator and corresponding snow melting machine product that can meet household needs.

[0007] As an optional solution, the inner cylinder wall and the outer cylinder wall are concentric rings, and a spiral condenser is provided between the inner cylinder wall and the outer cylinder wall. The spiral condenser is simultaneously attached to the inner cylinder wall and the outer cylinder wall, and the spiral condenser forms the spiral condensation channel.

[0008] The inner cylinder wall and the outer cylinder wall are arranged to be concentric rings, which is convenient for the production and processing of the outer cylinder and the inner cylinder. At the same time, a spiral condenser is arranged in the outer cylinder and the inner cylinder. The spiral condenser can be directly clamped between the inner cylinder and the outer cylinder, and can fit with the inner cylinder and the outer cylinder, so as to more fully realize the heat exchange between the refrigerant of the spiral condenser and the external food, thereby improving the cooling efficiency of the evaporator; at the same time, the concentric outer cylinder and the inner cylinder, and the clamped spiral condenser can better compress the volume space occupied by the outer cylinder and the inner cylinder, so as to increase the effective cooling processing area of ​​the evaporator, so as to compress the overall volume of the evaporator and the corresponding snow melting machine.

[0009] As an optional scheme, the outer side wall of the inner cylinder wall is provided with an outer spiral groove, the inner cylinder wall is fitted with the inner side wall of the outer cylinder wall, and the outer spiral groove forms the spiral condensation channel; or, the inner side wall of the outer cylinder wall is provided with an inner spiral groove, the outer cylinder wall is fitted with the outer side wall of the inner cylinder wall, and the inner spiral groove forms the spiral condensation channel; or, the inner side wall of the outer cylinder wall is provided with an inner spiral groove, and the outer side wall of the inner cylinder wall is provided with an outer spiral groove, and the inner spiral groove and the outer spiral groove are arranged relative to each other and enclose each other to form the spiral condensation channel.

[0010] A spiral groove can also be directly provided on the outer wall of the outer cylinder, or on the inner wall of the inner cylinder. For example, an outer spiral groove can be provided on the outer wall of the inner cylinder. When the outer cylinder is sleeved on the outer wall of the inner cylinder, the outer wall of the outer cylinder fits on the top of the outer spiral groove, so that a spiral condensation channel that is interconnected is formed between the outer cylinder wall and the outer spiral groove. Since the outer spiral groove is directly processed from the outer surface of the inner cylinder wall and directly fits with the inner surface of the outer cylinder, both the outer cylinder and the inner cylinder can more directly achieve heat exchange between the refrigerant and the food in the spiral condensation channel. At the same time, the outer spiral groove is directly processed on the outer wall of the inner cylinder wall, and a separate spiral condensation tube is no longer required, which reduces accessories and reduces costs. It can also further compress the volume of the outer cylinder and the inner cylinder to provide a small-volume, high-efficiency evaporator. According to different structural requirements, or in order to improve the refrigeration efficiency of the evaporator, an inner spiral groove can be provided on the inner wall of the outer cylinder wall and sleeved on the outside of the inner cylinder, and the inner spiral groove is in contact with the outer wall of the inner cylinder so that the inner spiral groove forms a spiral condensation channel; or, an inner spiral groove is provided on the inner wall of the outer cylinder wall and an outer spiral groove is provided on the outer wall of the inner cylinder wall at the same time. When the outer cylinder is sleeved on the outside of the inner cylinder, the inner spiral groove and the outer spiral groove correspond to each other and are clamped to form the spiral condensation channel, thereby achieving efficient refrigeration while compressing the volume of the evaporator and the corresponding snow melter.

[0011] As an optional solution, the evaporator further includes a condensation inlet pipe located between the outer cylinder wall and the inner cylinder wall, and the condensation inlet is communicated with the spiral condensation channel through the condensation inlet pipe.

[0012] A clamping condensation inlet pipe is directly arranged between the outer cylinder wall and the inner cylinder wall, so that the output refrigerant can be directly transported by the condensation inlet pipe to the front end of the evaporator, enter the spiral condensation channel, pass through the spiral condensation channel between the outer cylinder and the inner cylinder, and then flow back to the refrigeration component from the rear end. In this way, the heat exchange between the refrigerant and the food can be better guaranteed; and the condensation inlet pipe located between the outer cylinder and the inner cylinder will be transferred to the food outside the evaporator even if there is leakage of cooling heat, without excessive flux loss, so as to ensure the cooling efficiency of the evaporator.

[0013] As an optional solution, the length of the outer cylinder wall is greater than that of the inner cylinder wall, so that a built-in cavity is formed between the outer cylinder wall and the rear end wall of the inner cylinder wall, and the condensation inlet and the condensation outlet are arranged inside the built-in cavity.

[0014] The evaporator typically requires additional structures to achieve more specific functions, such as the connection structure between the condensation inlet and outlet and the outside; the agitator paddle structure of the snow melter based on the evaporator; and the snow melter's detection structure. The outer cylinder is longer than the inner cylinder. Since the front ends of the outer and inner cylinders are sealed and connected, the internal space forms a storage and installation space between the interior of the outer cylinder and the rear end wall of the inner cylinder. The corresponding structural components of the evaporator can be installed within this storage and installation space, fully utilizing the spatial volume of the evaporator itself, improving the effective volume utilization of the evaporator, achieving efficient output from a small evaporator, and ultimately providing a compact and efficient snow melter.

[0015] Correspondingly, the present application also provides a high-efficiency snow melting machine, comprising a casing and a refrigeration component and a power component located in the casing, and a processing module arranged on the upper part of the casing, wherein the processing module comprises a mixing drum, an evaporator and a stirring paddle arranged in the mixing drum, the evaporator adopts the evaporator described in the aforementioned scheme, the outer cylinder wall forms a condensation chamber in the mixing drum, the inner cylinder wall and the inner end wall form an inner condensation chamber connected to the condensation chamber inside the evaporator, the stirring paddle comprises an outer stirring paddle and an inner stirring paddle, the outer stirring paddle is sleeved on the outside of the outer cylinder wall, and the inner stirring paddle is arranged in the inner condensation chamber.

[0016] First, the outer wall of the evaporator forms a condensation chamber within the mixing drum for cooling the food. Furthermore, an inner condensation chamber is formed within the inner drum, communicating with the condensation chamber. The outer and inner drums simultaneously perform the condensation function, increasing the cooling area of ​​the evaporator within the mixing drum and improving the evaporator's cooling efficiency. Consequently, a smaller evaporator and mixing drum can achieve food cooling requirements. Furthermore, the inner condensation chamber is formed within the inner drum, reducing the volume occupied by the evaporator within the mixing drum, thereby increasing the effective volume within the mixing drum and improving the effective utilization rate of the mixing drum. This meets the need for processing large amounts of food within a small mixing drum, ultimately providing users with a compact, easy-to-operate, and efficient snow melter product that better meets the needs of home use. Of course, evaporators and snow melters using this method are also suitable for large-volume and large-capacity products. Due to the improved cooling efficiency of the evaporator itself, the snow melter can shorten the time it takes to process a single serving of food, better meeting the needs of rapid processing in commercial applications. Furthermore, the low heat loss and high cooling efficiency also achieve energy conservation and consumption reduction. An inner stirring paddle is further provided inside the inner cylinder to realize efficient turning of the food in the inner condensation chamber and to promote mixing of the food in the inner condensation chamber and the food in the condensation chamber to avoid local excessive cooling.

[0017] As an optional solution, a driving section is provided at the front end of the inner stirring paddle, the outer stirring paddle is connected to the inner stirring paddle via the driving section, and the inner stirring paddle drives the outer stirring paddle to rotate.

[0018] A driving section is directly set at the front end of the inner stirring paddle, and the outer stirring paddle is directly connected to the inner stirring paddle through the driving section. In this way, the outer stirring paddle can be driven at the same time as the inner stirring paddle, avoiding the need for multiple drive modules when driving the inner and outer stirring paddles separately. Moreover, the outer stirring paddle and the inner stirring paddle are directly driven and connected, which makes it more convenient to set the synchronous rotation of the outer stirring paddle and the inner stirring paddle, so as to better enable the inner stirring paddle to stir and mix the food in the inner condensation chamber and the food in the mixing drum.

[0019] As an optional solution, the rear end of the inner stirring paddle is provided with a transmission shaft connected to the power assembly, and the center of the rear end wall of the inner cylinder wall is also provided with a through hole for the transmission shaft to pass through.

[0020] The inner and outer cylinders are configured as concentric rings, facilitating the rotation of the outer and inner stirring paddles outside and inside the outer cylinder, respectively. Furthermore, the outer stirring paddles and the outer wall of the outer cylinder, as well as the inner stirring paddles and the inner wall of the inner cylinder, provide a better fit. This allows the outer stirring paddles to completely remove cooking ingredients from the outer wall of the outer cylinder, and the inner stirring paddles to completely remove cooking ingredients from the inner wall of the inner cylinder, preventing the ingredients from accumulating on the outer surface of the evaporator and overcooling. A through-hole for a drive shaft to pass through is provided directly at the rotation center of the rear end wall of the folded inner cylinder wall. The drive shaft is provided at the rear end of the inner stirring paddle and passes through the through-hole. The drive shaft is used to drive the inner and outer stirring paddles, resulting in more efficient transmission.

[0021] As an optional solution, the outer stirring paddle includes a spirally arranged outer blade, and the outer blade is in contact with the outer wall of the outer cylinder wall; the inner stirring paddle includes a spirally arranged inner blade, and the inner blade is in contact with the inner wall of the inner cylinder wall.

[0022] The spiral outer blades formed by the outer stirring paddle are in contact with the outer side wall of the outer drum, and the spiral inner blades formed by the inner stirring paddle are in contact with the inner side wall of the inner drum. Firstly, the spiral outer and inner blades can better push the ingredients in the mixing drum and turn and mix the ingredients. Moreover, the mutual contact with the outer and inner walls ensures that the outer and inner blades can effectively scrape the ingredients off the surfaces of the outer and inner drums, preventing the ingredients from being overcooled due to continued adhesion to the surface of the evaporator, which would affect the final processing of the ingredients.

[0023] As an optional solution, the evaporator is further provided at the rear end of the inner cylinder with a through hole penetrating the inner cylinder and the outer cylinder, and the through hole connects the inner condensation chamber and the condensation chamber.

[0024] A through hole is set at the rear end of the inner cylinder and penetrates the inner cylinder and the outer cylinder, so that the food in the inner condensation chamber can better flow back to the condensation chamber of the mixing cylinder through the through hole, better ensuring the flipping, stirring and mixing of the food in the chamber, thereby improving the processing efficiency of the snow melting machine.

[0035] like Figure 1-8As shown, the utility model discloses a snow melter using a high-efficiency evaporator and the evaporator. The evaporator includes a cylinder and an evaporator bracket 3 for fixing the cylinder. The cylinder includes an outer cylinder and an inner cylinder. The outer cylinder is an annular cylinder and includes an outer cylinder wall 1. The inner cylinder is an annular cylinder similar to the outer cylinder. The inner cylinder is provided with an inner cylinder wall 2. The front end of the inner cylinder wall 2 is sealed and connected to the front end of the outer cylinder wall 1 to form an internal space 5 between the outer cylinder and the inner cylinder. The evaporator also includes a spiral condensation channel provided in the internal space 5. Preferably, a spiral condensation tube 4 is actually provided on the outer cylinder wall 1 and the inner cylinder wall 2. The internal pipe of the spiral condensation tube 4 constitutes the spiral condensation channel. The spiral condenser tube 4 is simultaneously in contact with the inner wall of the outer cylinder wall 1 and the outer wall of the inner cylinder wall 2, thereby forming a condensation surface on the outer wall of the outer cylinder wall 1 and the inner wall of the inner cylinder wall 2. When the food comes into contact with the outer wall of the outer cylinder wall 1 and the inner wall of the inner cylinder wall 2, respectively, the food can be cooled. Compared with the evaporator having only a single outer surface in the prior art, the cooling area of ​​the evaporator is increased. At the same time, an inner condensation chamber 6 is formed inside the inner cylinder wall 2. The inner condensation chamber 6 also increases the cooling capacity of the evaporator and reduces the volume occupied by the evaporator itself. The evaporator placed in the snow melter occupies less space, which can improve the space utilization of the snow melter and make the evaporator work more efficiently.

[0036] Correspondingly, the utility model also discloses a highly efficient snow melting machine, which includes a casing and a refrigeration component and a power component located in the casing, and a processing module arranged on the upper part of the casing, wherein the processing module includes a mixing drum 10, an evaporator and a stirring paddle, and the evaporator and the stirring paddle are arranged in the mixing drum 10. As mentioned above, the evaporator includes an outer cylinder and an inner cylinder, the outer cylinder has an outer cylinder wall 1, and the inner cylinder has an inner cylinder wall 2. The outer cylinder wall 1 and the inner cylinder wall 2 are both annular cylinders, and the outer cylinder wall 1 is sleeved on the outside of the inner cylinder wall 2. The front ends of the outer cylinder wall 1 and the inner cylinder wall 2 are closed and connected to form an internal space 5 between the outer cylinder wall 1 and the inner cylinder wall 2. A spiral condenser 4 is arranged in the internal space 5, and the spiral condenser 4 is simultaneously in contact with the inner side wall of the outer cylinder wall 1 and the outer side wall of the inner cylinder wall 2, so that the outer side wall of the outer cylinder wall 1 and the inner side wall of the inner cylinder wall 2 both form a cooling surface. A condensation chamber 11 is formed inside the mixing drum 10, and an inner condensation chamber 6 is formed on the inner drum wall 2 and is connected to the condensation chamber 11. The stirring paddle includes an outer stirring paddle mounted on the outside of the outer drum and an inner stirring paddle located inside the inner drum. The outer stirring paddle and the inner stirring paddle are used to connect the inner condensation chamber and the condensation chamber, and the food placed in the mixing drum can flow freely between the condensation chamber and the inner condensation chamber, thereby achieving simultaneous cooling of the condensation chamber and the inner condensation chamber. In this way, the working efficiency of the evaporator and the snow melter is improved; moreover, the evaporator only occupies the space between the outer drum and the inner drum, while the interior of the inner drum can also be cooled, thereby improving the space and volume utilization of the mixing drum and making the refrigeration work of the snow melter more efficient.

[0037] Example 1.

[0038] As a first embodiment of the utility model using a high-efficiency evaporator, Figure 1 、 2 Specifically, the evaporator includes a barrel and an evaporator bracket 3 for fixing the barrel. The barrel includes an inner barrel and an outer barrel, and the inner barrel and the outer barrel are concentric rings. The outer barrel includes an annular outer barrel wall 1, and the inner barrel includes an annular inner barrel wall 2 and an inner end wall 9. The inner end wall 9 closes the rear end opening of the inner barrel wall 2. The outer barrel wall 1 is sleeved on the outside of the inner barrel, and the front ends of the outer barrel wall 1 and the inner barrel wall 2 are sealed and connected, so that the barrel forms an opening at the front end that communicates with the interior of the inner barrel wall 2.

[0039] The outer cylinder and the inner cylinder form an internal space 5 inside, and the evaporator also includes a spiral condensation channel arranged in the internal space 5. Preferably, a spiral condensation tube 4 is clamped between the outer cylinder wall 1 and the inner cylinder wall 2, and the spiral condensation tube 4 forms the spiral condensation channel. The spiral condensation tube 4 is simultaneously fitted with the inner side of the outer cylinder wall 1 and the outer side of the inner cylinder wall 2. On the one hand, the outer cylinder wall 1 and the inner wall 2 are directly fitted, which reduces the space occupied by the outer cylinder wall 1 and the inner cylinder wall 2, and can improve the space utilization of the evaporator itself; on the other hand, the outer cylinder wall and the inner cylinder wall are directly fitted with the spiral condensation tube, and the refrigerant of the spiral condensation tube can directly exchange heat with the external food, reduce the intermediate transfer path, improve the heat exchange efficiency of the evaporator, and achieve more efficient and faster refrigeration of the evaporator.

[0040] An inner condensation chamber 6 is formed between the inner cylinder wall 2 and the inner end wall 9. When the evaporator is installed in a snow melter, the outer cylinder wall 1 and the inner cylinder wall simultaneously form a cooling surface for cooling food, increasing the cooling area of ​​the evaporator and thereby improving the evaporator's cooling efficiency. The inner condensation chamber further increases the effective utilization rate of the evaporator's space. When used in a snow melter, it can also increase the utilization rate of the snow melter, making a small-sized snow melter meet user needs, making it particularly suitable for use in a home environment.

[0041] The evaporator is also provided with a condensation inlet 7 and a condensation outlet 8 connected to the spiral condenser tube. The external condensing agent flows into the evaporator through the condensation inlet 7, passes through the spiral condenser tube 4, and is discharged from the condensation outlet 8 and refluxes to the refrigeration module. The spiral structure of the spiral condenser tube 4 increases the distance of the spiral condensation channel in the evaporator, so that the condensing agent can fully exchange heat with the food in the evaporator to improve the working efficiency of the evaporator. Preferably, the axial length of the outer tube wall 1 is greater than the axial length of the inner tube wall 2. Since the front ends of the outer tube wall 1 and the inner tube wall 2 are closed and connected to form a common front end, the outer tube wall 1 has an internal space 5 at the rear end of the inner end wall 9. Preferably, the condensation inlet 7 and the condensation outlet 8 are located in the internal space 5 at the rear end of the inner end wall 9.

[0042] Based on the existing evaporator, an inner cylinder is further provided, and an outer cylinder is sleeved on the outer portion of the inner cylinder. The outer and inner cylinders sandwich the spiral condensation channel, and the inner cylinder forms an inner condensation chamber. This increases the cooling area of ​​the evaporator and the volume utilization of the cooling space of the evaporator. Ultimately, an evaporator with high cooling efficiency, high space utilization, and high efficiency can be provided.

[0043] It can be understood that the inner side wall of the outer cylinder wall is directly processed to form an inner spiral groove. When the outer cylinder wall is sleeved on the inner cylinder wall, the inner spiral groove fits with the outer side wall of the inner cylinder wall to close the inner spiral groove, and the spiral condensation channel is directly formed by the inner spiral groove. Alternatively, the outer side wall of the inner cylinder wall is directly processed to form an outer spiral groove. When the outer cylinder wall is sleeved outside the inner cylinder wall, the outer spiral groove fits with the inner side wall of the outer cylinder wall to close the outer spiral groove, and the spiral condensation channel is directly formed by the outer spiral groove. Alternatively, the inner side wall of the outer cylinder wall is directly processed to form an inner spiral groove. The outer side wall of the inner cylinder wall is formed with an outer spiral groove. When the outer cylinder wall is sleeved outside the inner cylinder wall, the outer spiral groove and the inner spiral groove are arranged relative to each other and fit together, and the inner spiral groove and the outer spiral groove together form the spiral condensation channel. The spiral condensation channel is formed directly from the outer cylinder or the inner cylinder, and a separate spiral condensation tube is no longer required, thereby reducing the number of accessories of the evaporator and ensuring that the refrigerant directly exchanges heat with the outer cylinder and the inner cylinder, thereby further improving the refrigeration efficiency of the evaporator.

[0044] It can be understood that the rear end of the evaporator can also be provided with a feed hole connecting the inner condensation chamber and the condensation chamber. The food can flow into the inner condensation chamber from the front end opening of the inner condensation chamber, and after passing through the inner condensation chamber, it is discharged at the rear end through the feed hole.

[0045] Example 2.

[0046] As a first embodiment of the utility model, a highly efficient snow melting machine is used. Figure 3-5 As shown. Specifically, the snow melt machine includes a housing and a refrigeration component and a power component located in the housing. The housing can be set to a corresponding shape according to the different shapes and layout requirements of the snow melt machine. The refrigeration component and the power component are placed in corresponding functional areas according to the shape and spatial structure of the housing. They will not be described in detail here. It should be noted that the embodiment 1 of the evaporator and the embodiment 1 of the snow melt machine described separately do not mean that the individual cases between the several embodiments are completely independent of each other, but are only for the purpose of specifically illustrating several preferred technical solutions of the evaporator and the snow melt machine, and the technical features and technical solutions of the several embodiments are universal and can be used for reference.

[0047] The snow melter also includes a processing module disposed within the housing. Preferably, the processing module is disposed above the housing. The processing module further includes a mixing drum 10, an evaporator, and a stirring paddle. Both the evaporator and the stirring paddle are disposed within the mixing drum 10. As previously described, the evaporator includes a barrel and an evaporator bracket 3 for securing the barrel. The evaporator is fixedly connected to the mixing drum 10 via the evaporator 3.

[0048] The evaporator further includes an outer cylinder and an inner cylinder, the inner cylinder and the outer cylinder being concentrically annular. The outer cylinder includes an annular outer cylinder wall 1, and the inner cylinder includes an annular inner cylinder wall 2 and an inner end wall 9. The inner end wall 9 closes the rear end opening of the inner cylinder wall 2. The outer cylinder wall 1 is sleeved on the outside of the inner cylinder, and the front ends of the outer cylinder wall 1 and the inner cylinder wall 2 are sealed and connected, so that the front end of the cylinder body forms an opening that communicates with the interior of the inner cylinder wall 2.

[0049] A spiral condenser tube 4 is sandwiched between the outer cylinder wall 1 and the inner cylinder wall 2, and the spiral condenser tube 4 is in contact with both the inner side of the outer cylinder wall 1 and the outer side of the inner cylinder wall 2. A condensation chamber 11 is formed inside the mixing cylinder 10 where the evaporator is installed, and an inner condensation chamber 6 is formed between the inner cylinder wall 2 and the inner end wall 9. The inner condensation chamber 6 and the condensation chamber 11 are connected by the front end opening of the inner cylinder, so that the food placed in the mixing cylinder can flow between the condensation chamber 11 and the inner condensation chamber 6. In this way, the cooling area of ​​the evaporator is increased by utilizing the outer cylinder wall and the inner cylinder wall, and the space utilization rate of the mixing cylinder is improved by utilizing the inner condensation chamber, so that the refrigeration efficiency of the snow melt machine is more efficient.

[0050] The stirring paddle includes an outer stirring paddle 12 and an inner stirring paddle 13. The outer stirring paddle 12 is sleeved on the outside of the outer cylinder wall 1, and the inner stirring paddle 13 is inserted into the inner condensing chamber 6. The front end of the inner stirring paddle 13 is provided with a driving section 14, and the front end of the outer stirring paddle 12 is also provided with a front stirring blade 15. The driving section 14 and the front stirring blade 15 are plugged into each other, and the driving section 14 is used to drive the outer stirring paddle 12. Preferably, the inner stirring paddle 13 is connected to the power component of the snow melter and is driven by the power component, and the inner stirring paddle 13 then drives the outer stirring paddle 12 to rotate together.

[0051] Preferably, the outer stirring paddle 12 includes a stirring end plate 18, an outer blade 19, a transmission section 20 and a stirring bracket 21. The stirring end plate 18 is located at the rear end of the outer stirring paddle 12, and the stirring bracket 21 and the outer blade 19 are connected to the stirring end plate 18. Preferably, the stirring bracket 21 is configured to be cylindrical extending in the axial direction, and the outer blade 19 is spirally extended in the axial direction. The outer blade 19 and the stirring bracket 21 can be provided in plurality. In this embodiment, the outer blade 19 and the stirring bracket 21 are both configured to be two, and intersect in the axial direction to increase the structural strength of the outer blade 19 and the stirring bracket 21. The front stirring blade 15 is connected to the outer blade 19 and the stirring bracket 21 at the front end, and the transmission section 20 is provided at the center position of the front stirring blade 15. Preferably, the cross section of the transmission section 14 is triangular, and accordingly, a triangular countersunk hole with the same cross section as the transmission section 14 is provided in the transmission section 20, and the transmission section 14 can extend into the countersunk hole of the transmission section 20, so that the inner stirring paddle drives the outer stirring paddle. Accordingly, the outer side of the inner stirring paddle 13 is provided with an inner blade 22, and the rear end of the inner stirring paddle 13 is also provided with a transmission shaft 23 connected to the power assembly, and the center of the inner end wall 3 is also provided with a through hole 30, and the transmission shaft 23 passes through the through hole 30 and is connected to the power assembly 24. Preferably, the evaporator is also provided with a sealing member sleeved on the outside of the transmission shaft 23 at the through hole to prevent the food in the mixing drum 10 from leaking out of the through hole.

[0052] When the outer stirring paddle is mounted on the outside of the outer cylinder, the outer blades 19 fit against the outer wall of the outer cylinder wall 1, reducing the gap between the outer stirring paddle 12 and the outer cylinder. Simultaneously, the inner blades 22 located within the inner condensing chamber 6 fit against the inner wall of the inner cylinder wall 2, reducing the gap between the outer stirring paddle 13 and the inner cylinder. This allows the outer stirring paddle 12 and the inner stirring paddle 13 to rotate and peel off the food on the outer and inner cylinder surfaces, preventing the food from being overcooled by continued contact with the evaporator.

[0053] The processing module further includes a discharge port 16 and a handle 17 provided on the front side of the mixing drum 10 . The handle 17 is operated to open the discharge port 16 to discharge the food processed by the mixing drum.

[0054] Compared to conventional snow melters, this application changes the structure of the evaporator, utilizing the inner cylinder to increase the cooling area of ​​the evaporator and improve its cooling efficiency. Furthermore, the inner and outer cylinders directly adhere to the spiral condensation channel, further increasing the heat exchange efficiency of the evaporator's outer surface. An internal condensation chamber is further formed within the inner cylinder, improving the space utilization within the mixing drum. Compared to existing mixing drum structures, more food can be processed within a smaller mixing drum volume. As a result, the snow melter achieves a smaller size, easier operation, and more efficient processing, making it better suited to home use.

[0055] Example 3.

[0056] As a second embodiment of the efficient snow melting machine described in the utility model, Figure 6 、 7 As shown, compared to Example 2, the evaporator in this embodiment further includes a feed hole at the rear end, through which the inner condensation chamber is connected to the condensation chamber at both the front and rear ends. It should be noted that the specific examples 1 and 2 described separately do not mean that the individual examples are completely independent of each other, but are merely for the purpose of specifically illustrating several preferred technical solutions. The technical features and technical solutions of the several examples are universal and can be used for reference.

[0057] like Figure 6 、 7 As shown, the snow melter includes a processing module disposed above the housing. The processing module includes a mixing drum 10, an evaporator disposed within the mixing drum 10, and a stirring paddle. As previously described, the evaporator includes a barrel and an evaporator bracket 3 for securing the barrel. The processing module also includes a fixing bracket 25 disposed within the mixing drum 10. The rear end of the fixing bracket 25 is fixedly connected to the side wall of the mixing drum 10, and the evaporator is fixed to the front end of the fixing bracket 25, thereby securing the evaporator within the mixing drum 10.

[0058] Preferably, a fixing platform 26 fixedly connected to the evaporator is provided at the front end of the fixing bracket 25. The fixing platform 26 is arranged in a ring shape to cooperate with the evaporator. The fixing platform 26 and the rear end are connected by a fixed connecting column, so that a stirring channel 27 is formed between the fixing platform 26 and the fixed connecting column.

[0059] The cylinder body includes an outer cylinder and an inner cylinder, the outer cylinder includes an annular outer cylinder wall 1, the inner cylinder includes an annular inner cylinder wall 2, the outer cylinder wall 1 is sleeved on the outside of the inner cylinder wall 2, the outer cylinder wall 1 and the inner cylinder wall 2 are concentric rings, the front and rear ends of the outer cylinder wall 1 and the inner cylinder wall 2 are closed and connected, and an internal space 5 is formed inside. The evaporator also includes a spiral condenser 4 arranged in the internal space 5, and the spiral condenser 4 is simultaneously fitted with the inner wall of the outer cylinder wall 1 and the outer wall of the inner cylinder wall 2. An internal condensation chamber 6 is formed inside the inner cylinder wall 2. Preferably, the cooling inlet and cooling outlet of the evaporator are arranged at the rear end connection of the outer cylinder wall 1 and the inner cylinder wall 2, and pass through the outer cylinder wall 1 and the inner cylinder wall 2.

[0060] The cylinder body is formed into a cylindrical shape with front and back openings by the outer cylinder and the inner cylinder, so as to form a feed hole 28 passing through the inner cylinder and the outer cylinder at the rear end of the cylinder body, and the feed hole 28 connects the inner condensation chamber 6 and the condensation chamber 11. The outer side of the outer cylinder wall 1 is provided with an outer stirring paddle 12, and the inner condensation chamber 6 located in the inner cylinder wall 2 is provided with an inner stirring paddle 13. The inner stirring paddle 13 and the outer stirring paddle 12 are detachably connected at the front end so that the inner stirring paddle 13 drives the outer stirring paddle 13. Since the front and rear ends of the inner condensation chamber 6 are both connected to the condensation chamber 11 in the mixing drum 10, when the inner stirring paddle 13 is working, the food can be sucked into the inner condensation chamber 6 from the front opening of the cylinder. Under the pushing action of the inner stirring paddle, it is in full contact with the inner wall of the inner cylinder wall 2 to exchange heat with the condensing agent in the spiral condenser tube to achieve cooling of the food. The cooled food is discharged from the rear opening of the cylinder and refluxed into the condensation chamber 11 through the stirring channel 27 of the fixed bracket 25, finally achieving full mixing and stirring of the food in the condensation chamber 11 and the inner condensation chamber 6, improving the uniformity of the cooled food, and improving the efficiency of the snow melter by increasing the cooling area and increasing the cooling space. The processing module of the snow melter also includes a temperature sensor, which extends into the condensation chamber to detect the temperature of the food. Preferably, the temperature sensor is arranged on the evaporator, for example, at the front end of the cylinder.

[0061] The inner cylinder of the evaporator is used to form an inner cylinder wall that increases the cooling area, thereby improving the cooling speed; at the same time, the inner cylinder wall is used to form an inner condensation chamber, thereby improving the space utilization of the snow melter, and realizing the cooling processing of more food materials in a smaller space volume, thereby ultimately providing users with a light, compact, and efficient snow melter.

[0062] It can be understood that the internal stirring paddle can also drive the food to flow through the stirring channel 27 to the rear end of the cylinder, and flow from the rear end into the internal condensation chamber 6 in the cylinder. After heat exchange in the internal condensation chamber 6, it is discharged from the front end of the cylinder and mixed and stirred with the food in the condensation chamber.

[0063] Example 4.

[0064] As a second embodiment of the present invention using a high-efficiency evaporator, Figure 8 As shown, compared to the first embodiment of the evaporator, this embodiment further includes a condensation inlet pipe. It should be noted that the first and second embodiments of the evaporator and the first and second embodiments of the snow melter are not intended to be completely independent of each other. They are merely intended to specifically illustrate several preferred technical solutions. The technical features and technical solutions of the several embodiments are universal and can be used for reference.

[0065] like Figure 8 As shown, the evaporator includes a cylinder and an evaporator bracket that fixes the cylinder. The cylinder includes an inner cylinder and an outer cylinder, and the inner cylinder and the outer cylinder are concentric rings. The outer cylinder includes an annular outer cylinder wall 1, and the inner cylinder includes an annular inner cylinder wall 2. The outer cylinder wall 1 is sleeved on the outside of the inner cylinder wall 2, and the front ends of the outer cylinder wall 1 and the inner cylinder wall 2 are sealed and connected, so that the cylinder forms an opening at the front end that communicates with the interior of the inner cylinder wall 2. A spiral condenser tube 4 is sandwiched between the outer cylinder wall 1 and the inner cylinder wall 2, and the spiral condenser tube 4 is simultaneously in contact with the inner side of the outer cylinder wall 1 and the outer side of the inner cylinder wall 2.

[0066] The evaporator is further provided with a condensation inlet and a condensation outlet 8 connected to the spiral condensation tube 4. Preferably, the evaporator further includes a condensation inlet pipe 29, which is located between the outer cylinder wall 1 and the inner cylinder wall 2 and extends into the front end of the cylinder to be connected to the spiral condensation tube 4 at the front end.

[0067] When the evaporator is installed on the snow melter, the refrigeration component of the snow melter is connected to the spiral condenser tube 4 through the condensation inlet pipe 29, so that the refrigerant is directly injected from the condensation inlet pipe into the front end of the spiral condenser tube 4, and after passing through the spiral condenser tube 4, it is discharged from the condensation outlet 8 located at the rear end of the evaporator and refluxes into the refrigeration component.

[0068] Preferably, the spiral condenser tube 4 can be flattened or provided with a groove at the intersection between the outer and inner cylinder walls and the condensation inlet tube 29, so that the condensation inlet tube extends from the rear end to the front end. This ensures that the outer wall of the outer cylinder wall and the inner wall of the inner cylinder wall, which come into contact with the food and condense it, maintain smooth rotating surfaces, thus ensuring stable operation of the outer and inner stirring paddles and preventing food residue from remaining in blind spots.

[0069] It can be understood that the side wall of the outer cylinder wall or the inner cylinder wall is provided with a groove, and the condensation inlet pipe is arranged in the groove of the outer cylinder wall or the inner cylinder wall and extends from the rear end of the cylinder into the front end.

[0070] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0071] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned "below other devices or structures" or "below other devices or structures", but it does not mean that the actual device is inverted. Therefore, the exemplary term "above" can include both "above" and "below". The device can also be rotated 90 degrees or in other orientations in other same orientations, and the spatially relative descriptions used here are interpreted accordingly.

[0072] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise specified, the above terms have no special definition and therefore cannot be understood as limiting the scope of protection of this application.
