Description

Technical Field

[0001] This invention relates to the field of snow melting machine technology, and in particular to a dual-purpose vertical snow melting machine. Background Technology

[0002] In the current frozen beverage market, slush machines (also known as ice cream makers) have become indispensable tools for making smoothies and frozen drinks, and their applications are becoming increasingly widespread. As people's pursuit of quality of life continues to improve, slush machines are no longer limited to commercial use but are gradually being adopted by households. However, the scrapers that traditional slush machines come with are usually flat, strip-shaped structures. These scrapers have a relatively weak stirring effect on the ice crystal mixture, typically only functioning to push the mixture forward. This results in insufficient stirring of the ice crystal mixture, poor fluidity of the ice crystals on the scraper, and insufficient contact with air. Therefore, they can only produce larger, smoothie-like solids, unable to create smaller, softer "ice cream"-like solids, failing to meet diverse user needs. Furthermore, existing horizontal slush machine designs are mostly commercial, and commercial slush machines generally adopt a horizontal structure, where the motor is placed horizontally and connected horizontally to the evaporator, forming a horizontal parallel layout. This structure results in a larger horizontal footprint and a larger overall size. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a dual-purpose vertical snow melting machine that can make both ice cream and slushies, which can meet the different needs of users, and can save horizontal space and is compact in size.

[0004] To solve the above-mentioned technical problems, the present invention provides a dual-purpose vertical snow melting machine, including a shell, a refrigeration component, a discharge component, a drive component, and a stirring component.

[0005] The driving assembly includes a driving motor, and the stirring assembly includes a first scraper or a second scraper that is drivenly connected to the driving motor. The storage cylinder and the evaporator are vertically arranged, and the first scraper or the second scraper is located inside the storage cylinder and outside the evaporator.

[0006] The first scraper is provided with an ice cream scraper part, which extends spirally downward along the inner wall of the storage cylinder.

The two ice cream scraper parts extend downward from the first connecting part in an alternating spiral pattern.

[0009] As an improvement to the above solution, the inner and outer sides of the ice cream scraper are further provided with multiple protruding plates.

[0010] On the inner and outer sides of the same ice cream scraper, the notch and the convex plate are alternately arranged; at the same horizontal position of the same ice cream scraper, when the notch is located on the inner side of the ice cream scraper, the convex plate is located on the outer side of the ice cream scraper, and when the notch is located on the outer side of the ice cream scraper, the convex plate is located on the inner side of the ice cream scraper.

[0011] At the same horizontal position, the position of the notch and the convex plate of one ice cream scraper part corresponds to the position of the convex plate and the notch of the other ice cream scraper part.

[0012] As an improvement to the above solution, the second scraper also includes a second connecting part, which is connected to the drive motor. The number of ice slush scraper parts is multiple and they are evenly distributed on the edge of the second connecting part. The bottom of the ice slush scraper part is provided with a pushing part, which is curved in an arc shape. The bending direction of the pushing part is opposite to the rotation direction of the second scraper.

[0013] As an improvement to the above solution, the evaporator includes an outer cylinder and a heat exchange tube, the heat exchange tube being disposed on the inner wall of the outer cylinder, the drive assembly further includes a partition cylinder disposed inside the outer cylinder, the drive motor being disposed inside the partition cylinder, and a foaming layer being provided between the outer wall of the partition cylinder and the inner wall of the outer cylinder.

[0014] As an improvement to the above solution, the drive assembly further includes a transmission rod, with the movable end of the drive motor facing upwards, one end of the transmission rod connected to the movable end of the drive motor, and the other end of the transmission rod passing upwards through the top of the partition cylinder and connected to the first scraper or the second scraper.

[0015] As an improvement to the above solution, the refrigeration assembly further includes a compressor, a condenser, and a throttling device disposed within the bottom shell. The discharge end of the compressor is connected to the condenser, the condenser is connected to the throttling device, the throttling device is connected to one end of the heat exchange tube, and the other end of the heat exchange tube is connected to the return gas end of the compressor.

[0016] As an improvement to the above solution, a heat dissipation plate is provided on one side of the bottom shell, and heat dissipation holes are provided on the heat dissipation plate. Vertical plates are provided on both the left and right sides of the heat dissipation plate, and a heat dissipation channel is formed between the two vertical plates. The condenser is located on the side of the heat dissipation plate. The condenser includes a condensing copper tube and copper tube ends. The condensing copper tube is set vertically, and the copper tube ends are located at the upper and lower ends of the condensing copper tube.

[0017] As an improvement to the above solution, the bottom of the storage cylinder is provided with a connecting port, and a transition channel is provided between the discharge cylinder and the storage cylinder. The connecting port is connected to the transition channel. The discharge cylinder is vertically arranged and has a discharge channel. The middle part of the discharge channel is connected to the transition channel. A discharge port is provided between the transition channel and the discharge channel. The discharge assembly also includes a movable handle. The discharge valve includes a baffle and a piston rod connected to each other. The baffle is slidably connected to the inner wall of the storage cylinder and can block the connecting port. The top of the piston rod is movably connected to the movable handle. The piston rod is slidably connected to the discharge channel and can block the discharge port.

[0018] As an improvement to the above solution, the housing also includes a rotating handle, which is rotatably connected to the side of the bottom shell. The rotating handle has a snap-fit ​​groove on the side near the bottom shell, and a limiting protrusion is provided at the bottom of the upper shell. After the rotating handle is rotated, the limiting protrusion can be snapped into the snap-fit ​​groove or disengaged from the snap-fit ​​groove.

[0023] Implementing this invention has the following beneficial effects:

[0024] This invention relates to a dual-purpose vertical slush machine, comprising a housing, a cooling component, a discharging component, a driving component, and a stirring component. The liquid is cooled in a storage cylinder within the housing. The stirring component is driven by a motor in the driving component. The stirring component includes either a first scraper or a second scraper. The first scraper has an ice cream scraper section with multiple notches on both its inner and outer edges. When the first scraper is used to stir the ice crystal mixture, the mixture moves through these notches, achieving better flowability and improving the stirring effect. This results in smaller ice crystal particles, ultimately forming ice cream. When the second scraper is used to stir the ice crystal mixture, it forms a smoothie. Therefore, this dual-purpose vertical slush machine can produce both ice cream and smoothies, meeting different user needs. In addition, since the storage cylinder of the housing and the evaporator of the refrigeration component are vertically arranged, and the ice cream scraper and the slush scraper extend downward, it can save horizontal space and achieve the effect of reducing volume compared to the horizontal placement method, making it more convenient to use in home settings.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0033] See Figure 1 and Figure 4 This invention discloses a dual-purpose vertical snow melting machine, including a housing 1, a refrigeration component 2, a discharge component 5, a drive component 3, and a stirring component 4. The housing 1 includes a bottom shell 11, a storage cylinder 12 disposed on the bottom shell 11, and an upper shell 13 covering the storage cylinder 12. The refrigeration component 2 includes an evaporator 21, which is cylindrical and disposed inside the storage cylinder 12. The discharge component 5 includes a discharge cylinder 51 and a discharge valve 52. The discharge cylinder 51 is connected to the storage cylinder 12, and the discharge valve 52 is used to control the opening and closing of the discharge cylinder 51. In use, liquids such as juice and dairy products are poured into the storage cylinder 12, and the evaporator 21 is started. The cylindrical outer wall of the evaporator 21 exchanges heat with and cools the liquid. After cooling to a certain temperature, the liquid produces ice crystals to form an ice crystal mixture. In order to prevent the ice crystal mixture from directly freezing into ice cubes, the drive component 3 drives the stirring component 4 to stir and push the ice crystal mixture so that the ice crystal mixture forms small-particle slush or even smaller-particle ice cream.

[0034] See Figure 2 and Figure 3 The driving assembly 3 includes a drive motor 31, and the stirring assembly 4 includes a first scraper 41 or a second scraper 42 that is connected to the drive motor 31. The first scraper 41 can make ice cream, and the second scraper 42 can make slushies. The first scraper 41 and the second scraper 42 are interchangeable, so both slushies and ice cream can be made. To save lateral space, the storage cylinder 12 and the evaporator 21 are vertically arranged. Since the height of the storage cylinder 12 and the evaporator 21 is greater than their diameter, the vertical placement of the storage cylinder 12 and the evaporator 21 saves lateral space, making them compact and more suitable for home use. The first scraper 41 or the second scraper 42 is located inside the storage cylinder 12 and outside the evaporator 21. The scraper and the second scraper 42 can stir the ice crystal mixture between the inner wall of the storage cylinder 12 and the outer wall of the evaporator 21.

[0035] Specifically, the first scraper 41 is provided with an ice cream scraper part 411, which extends spirally downward along the inner wall of the storage cylinder 12. Therefore, the ice cream scraper part 411 is also arranged longitudinally, which can save lateral space.

[0036] In a traditional horizontal snow melting machine, the drive motor 31 is placed horizontally and connected to the scraper. The storage cylinder 12 is placed horizontally. When the drive motor 31 drives the scraper to rotate, it can push the ice crystal mixture horizontally. The ice crystal mixture tends to accumulate at one end of the storage cylinder 12. Traditional snow melting machines use a backflow surface at this end of the storage cylinder 12 to allow the ice crystal mixture to flow back to the upper or lower side of the storage cylinder 12, preventing the ice crystal mixture from accumulating and forming large ice blocks under pressure. Traditional scrapers are all flat strip structures, which can only play a pushing role and a little stirring role. They cannot achieve sufficient stirring of the ice crystal mixture, nor can they increase the contact with air. Therefore, the final product is a large-particle solid, i.e., slush. In this embodiment of the invention, when the first scraper 41 rotates, it can push the ice crystal mixture downwards. Under the influence of gravity, the ice crystal mixture is more likely to aggregate and accumulate at the bottom of the storage cylinder 12. Even with the opening of the backflow surface, it is not easy for the ice crystal mixture to overcome gravity and flow back. Therefore, compared with the horizontal snow melting machine, the first scraper 41 has two problems when making ice cream. One is that the existing scraper structure cannot fully stir the ice crystal mixture, and the other is that the existing storage cylinder 12 structure cannot make the ice crystal mixture flow back smoothly, and cannot avoid the aggregation and formation of ice blocks.

[0037] To address the aforementioned issues, the outer side of the ice cream scraper 411 is located near the inner wall of the storage cylinder 12, while the inner side is located near the outer wall of the evaporator 21. Multiple notches 412 are provided on both the inner and outer edges of the ice cream scraper 411. By providing these multiple notches 412, the flow of the ice crystal mixture within the storage cylinder 12 is greatly facilitated. Under the downward squeezing force of the ice cream scraper 411, the ice crystal mixture can flow back, mix, and disperse within each notch 412. Therefore, the ice crystal mixture can smoothly flow back from the bottom to the middle or top of the storage cylinder 12, improving its fluidity and preventing it from accumulating at the bottom and forming ice cubes. Furthermore, the flow, mixing, and dispersion of the ice crystal mixture within the storage cylinder 12 further enhances the stirring effect, allowing the ice crystal mixture to fully mix with air, thus creating a soft, fluffy, and delicate ice cream.

[0038] The second scraper 42 is provided with an ice-slush scraper 421, which extends downward along the inner wall of the storage cylinder 12, thus saving lateral space. The surface of the ice-slush scraper 421 is provided with scraping ribs 424, which are located on the side of the ice-slush scraper 421 near the evaporator 21. The scraping ribs 424 can improve the stirring of the ice crystal mixture and prevent the ice crystal mixture from accumulating excessively to form ice blocks.

[0039] The beneficial effects of the embodiments of the present invention are as follows:

[0040] This invention relates to a dual-purpose vertical slush machine comprising a housing 1, a cooling assembly 2, a discharging assembly 5, a driving assembly 3, and a stirring assembly 4. The liquid is cooled in the storage cylinder 12 of the housing 1. The stirring assembly 4 is driven by a drive motor 31 of the driving assembly 3. The stirring assembly 4 includes a first scraper 41 or a second scraper 42. The first scraper 41 has an ice cream scraper section 411 with multiple notches 412 on both its inner and outer edges. When the first scraper 41 is used to stir the ice crystal mixture, the mixture moves through the notches 412, achieving better fluidity and improving the stirring effect. This results in smaller ice crystal particles, ultimately forming ice cream. When the second scraper 42 is used to stir the ice crystal mixture, it forms a smoothie. Therefore, this dual-purpose vertical slush machine can produce both ice cream and smoothies, meeting different user needs. In addition, since the storage cylinder 12 of the housing 1 and the evaporator 21 of the refrigeration component 2 are vertically arranged, and the ice cream scraper 411 and the slush scraper 421 extend downward, it can save horizontal space and achieve the effect of reducing volume compared to the horizontal placement method, making it more convenient to use in home settings.

[0041] See Figure 2 The first scraper component 41 further includes a first connecting part 413, which is connected to the drive motor 31. The first connecting part 413 can drive the ice cream scraper part 411 to rotate. There are two ice cream scraper parts 411, which are respectively located on opposite sides of the first connecting part 413. The two ice cream scraper parts 411 extend downward from the first connecting part 413 in an alternating spiral pattern.

[0042] Furthermore, to improve the stirring effect on the ice crystal mixture, the inner and outer sides of the ice cream scraper 411 are provided with multiple protruding plates 414, which can stir the ice crystal mixture. Furthermore, on both the inner and outer sides of the same ice cream scraper 411, the notches 412 and the protruding plates 414 are alternately arranged. That is, on the inner side of the same ice cream scraper 411, the notches 412 and the protruding plates 414 are alternately arranged, presenting a distribution structure of notch 412-protruding plate 414-notch 412-protruding plate 414… On the outer side of the same ice cream scraper 411, the notches 412 and the protruding plates 414 are also alternately arranged, presenting a distribution structure of notch 412-protruding plate 414-notch 412-protruding plate 414… By alternating these configurations, the ice crystal mixture can achieve relatively uniform stirring and flow in the vertical direction on both the inner and outer sides. Specifically, on the inner side, the ice crystal mixture moves under the pressure of the convex plate 414. Since both ends of the convex plate 414 are provided with notches 412, which are respectively located at the upper and lower ends of the convex plate 414, the ice crystal mixture will produce a flow-stirring-flow-stirring effect in the vertical direction, promoting vertical fluidity and improving the stirring effect in the vertical direction.

[0043] Furthermore, at the same horizontal position of the same ice cream scraper portion 411, when the notch 412 is located on the inner side of the ice cream scraper, the convex plate 414 is located on the outer side of the ice cream scraper; conversely, when the notch 412 is located on the outer side of the ice cream scraper, the convex plate 414 is located on the inner side of the ice cream scraper. This ensures that at the same horizontal height, the ice crystal mixture is not always flowing or always being compressed, but rather forms a state of inner flow and outer compression, or outer flow and inner compression. This allows the ice crystal mixture to be stirred more evenly and to flow more uniformly.

[0044] Furthermore, at the same horizontal position, the positions of the notch 412 and the convex plate 414 of one ice cream scraper portion 411 correspond to the positions of the convex plate 414 and the notch 412 of the other ice cream scraper portion 411. That is, at the same horizontal position, the position of the notch 412 of one ice cream scraper portion 411 corresponds to the position of the convex plate 414 of the other ice cream scraper portion 411, and the position of the convex plate 414 of one ice cream scraper portion 411 corresponds to the position of the notch 412 of the other ice cream scraper portion 411. During rotation, the ice cream scraper 411 pushes the ice crystal mixture to move, creating a horizontal component within the storage cylinder 12. This horizontal component allows the ice crystal mixture to flow through the notch 412. At the same height, the position of the protrusion 414 on one ice cream scraper 411 corresponds to the position of the notch 412 on the other ice cream scraper 411. Therefore, after passing through the notch 412, the ice crystal mixture encounters the protrusion 414, which pushes and stirs the mixture. Thus, in the horizontal direction, the ice crystal mixture experiences a repeated stirring and flowing effect, promoting both horizontal fluidity and stirring efficiency.

[0045] The above settings enable simultaneous vertical and horizontal stirring and flow, comprehensively improving fluidity and stirring effect in three dimensions.

[0046] See Figure 3 The second scraper component 42 also includes a second connecting part 422, which is connected to the drive motor 31. There are multiple slush scraper parts 421, which are evenly distributed on the edge of the second connecting part 422. Since not much additional stirring is required when making slush, the slush scraper part 421 is a long, straight plate. The slush scraper part 421 is vertically arranged, which reduces the downward squeezing effect on the ice crystal mixture compared to the traditional spiral scraper. Moreover, the scraper ribs 424 generate a horizontal pushing effect on the ice crystal mixture, which slows down the accumulation of the ice crystal mixture at the bottom of the storage cylinder 12. The bottom of the slush scraper part 421 is provided with a pushing part 423, which is curved in an arc shape. The bending direction of the pushing part 423 is opposite to the rotation direction of the second scraper component 42. By setting the arc-shaped extrusion part 423, a combined vertical downward and horizontal force can be generated on the ice crystal mixture located at the bottom of the storage cylinder 12, which is beneficial to make the generated ice sand discharged from the side of the storage cylinder 12.

[0047] See Figure 4In the evaporator 21, the evaporator 21 includes an outer cylinder 211 and a heat exchange tube 212. The heat exchange tube 212 is disposed on the inner wall of the outer cylinder 211, and a refrigerant is introduced into the heat exchange tube 212 to achieve the heat exchange effect of heat absorption and evaporation, thereby cooling the liquid outside the outer cylinder 211 and inside the storage cylinder 12 to make ice. In this embodiment of the invention, the drive motor 31 is disposed inside the outer cylinder 211. In traditional snow melting machines, the motor and evaporator 21 are separately disposed, with the motor's drive shaft passing through the evaporator 21 and connected to the scraper. This results in the motor, evaporator 21, and scraper forming a single unit that occupies a large amount of lateral space. By vertically arranging the storage cylinder 12, the evaporator 21, and the drive motor 31, and placing the drive motor 31 inside the evaporator 21, lateral space is saved, and longitudinal space is further saved by not having to place the motor above or below the evaporator 21. This saves both lateral and longitudinal space, achieving the effect of reducing the volume.

[0048] After the drive motor 31 is installed inside the evaporator 21, the heat exchange tube 212 will cool the drive motor 31 when it absorbs heat. However, after the machine stops, condensation will form on the surface of the drive motor 31, which may pose a safety hazard. To avoid the drive motor 31 from producing an undesirable cooling and condensation effect, the drive motor 31 is further isolated from the heat exchange tube 212. The drive assembly 3 also includes a partition cylinder 32, which is located inside the outer cylinder 211, and the drive motor 31 is located inside the partition cylinder 32. The partition 32 is used to isolate the drive motor 31, preventing the drive motor 31 from being directly affected by the cooling energy of the evaporator 21. A foam layer is provided between the outer wall of the partition 32 and the inner wall of the outer cylinder 211. The foam layer is usually made of polyurethane foam material. By reasonably setting the thickness of the foam layer, the cooling energy from the heat exchange tube 212 can be reasonably isolated, thereby avoiding the generation of condensate due to cooling. On the other hand, the foam layer can prevent the cooling energy of the heat exchange tube 212 from being transferred inward, ensuring the high efficiency of outward transfer.

[0049] The drive assembly 3 also includes a transmission rod 33. The movable end of the drive motor 31 is arranged upward. One end of the transmission rod 33 is connected to the movable end of the drive motor 31. The other end of the transmission rod 33 passes upward through the top of the partition cylinder 32 and is connected to the first scraper 41 or the second scraper 42. The drive motor 31 drives the first scraper 41 or the second scraper 42 from the top.

[0050] See Figure 5The refrigeration assembly 2 further includes a compressor 22, a condenser 23, and a throttling device 24 disposed within the bottom shell 11. The discharge end of the compressor 22 is connected to the condenser 23, the condenser 23 is connected to the throttling device 24, the throttling device 24 is connected to one end of the heat exchange tube 212, and the other end of the heat exchange tube 212 is connected to the return end of the compressor 22. The refrigeration system composed of the compressor 22, the condenser 23, the throttling device 24, and the evaporator 21 is a mature technology in the field, and the principles involved will not be elaborated here.

[0051] It should be noted that a heat dissipation plate 111 is provided on one side of the bottom shell 11, and heat dissipation holes 112 are provided on the heat dissipation plate 111. Vertical plates 113 are provided on both the left and right sides of the heat dissipation plate 111, forming a heat dissipation channel between the two vertical plates 113. The condenser 23 is located on the side of the heat dissipation plate 111. The condenser 23 includes a condensing copper tube 231 and copper tube ends 232. The condensing copper tube 231 is vertically arranged, and the copper tube ends 232 are located at the upper and lower ends of the condensing copper tube 231, thus the condenser 23 is horizontally placed. In traditional snow melting machines, the condensing copper tube 231 of the condenser 23 is horizontally placed, with the copper tube ends 232 located at the left and right ends of the condensing copper tube 231. The horizontal space of the condenser 23 needs to accommodate the condensing copper tubes 231 at both ends, thus requiring a relatively wide horizontal space. Moreover, the air blown into the condensing copper tube 231 cannot enter the fin gaps, resulting in poor heat dissipation. In the embodiment of the invention, by placing the condenser 23 horizontally and the copper tube end 232 located at the upper and lower ends of the condensing copper tube 231, the left and right ends of the condenser 23 can be directly connected to the vertical plate 113, and a heat dissipation channel can be formed between the two vertical plates 113. This not only saves lateral space on the left and right sides to make the volume compact, but also enables centralized air supply to dissipate heat from the condenser 23, thereby improving heat dissipation efficiency.

[0052] See Figure 6 and Figure 7In order to facilitate the smooth discharge of ice cream or shaved ice and prevent ice cream or shaved ice from accumulating on the side of the storage cylinder 12 and blocking the discharge port 512, the bottom of the storage cylinder 12 is provided with a connecting port 121. A transition channel 53 is provided between the discharge cylinder 51 and the storage cylinder 12. The connecting port 121 is connected to the transition channel 53. The discharge cylinder is vertically arranged and is provided with a discharge channel 511. The middle part of the discharge channel 511 is connected to the transition channel 53. A discharge port 512 is provided between the transition channel 53 and the discharge channel 511. When ice cream or smoothie is dispensed, it first enters the connecting port 121 and then the transition channel 53. In the transition channel 53, the ice cream or smoothie can be stored to a certain extent, achieving a transition effect. The dispensing assembly 5 also includes a movable handle 54. The dispensing valve 52 includes a baffle 521 and a piston 522 connected to each other. The baffle 521 is slidably connected to the inner wall of the storage cylinder 12 and can block the connecting port 121. The top of the piston 522 is movably connected to the movable handle 54. The piston 522 is slidably connected to the dispensing channel 511 and can block the dispensing port 512.

[0053] When ice making is in normal operation and no discharge is required, the baffle 521 can block the connecting port 121, and the piston column 522 can block the discharge port 512, so ice cream or shaved ice can be formed normally. When discharge is required, the movable handle 54 swings to move the baffle 521 and the piston column 522 to open the connecting port 121 and the discharge port 512. At this time, the ice cream or shaved ice first enters the connecting port 121, and then gradually moves from the connecting port 121 to the transition channel 53. After gradually moving to the discharge channel 511, the ice cream or shaved ice will be discharged from the discharge channel 511. Due to the addition of the transition channel 53, the transition channel 53 provides a lateral buffer for the discharge of ice cream or shaved ice. The ice cream or shaved ice can be spread in the transition channel 53 without gradually blocking the discharge port 512, thereby preventing the ice cream or shaved ice from blocking the discharge port 512. By reasonably setting the length and height of the transition channel 53, the volume of the transition channel 53 can be made larger than the volume between the discharge port 512 and the side wall of the discharge channel 511. Therefore, compared with the traditional horizontal snow melting machine, ice cream or shaved ice will not be blocked in the connecting port 121 in this embodiment of the invention as it is blocked in the discharge port 512 of the traditional snow melting machine, thus achieving a smooth ice removal effect.

[0054] See Figure 1 and Figure 5The upper shell 13 covers the storage cylinder 12 to protect it. The shell 1 also includes a rotating handle 14, which is rotatably connected to the side of the bottom shell 11. The rotating handle 14 has a locking groove 141 on the side near the bottom shell 11, and a limiting protrusion 131 is provided at the bottom of the upper shell 13. When the rotating handle 14 is rotated, the limiting protrusion 131 can either engage with the locking groove 141 or disengage from it. In use, rotating the rotating handle 14 causes the locking groove 141 to rotate, and the limiting protrusion 131 engages with the locking groove 141 to form a limiting and fixing position, ensuring the stability of the upper shell 13. When the storage cylinder 12 needs to be cleaned or inspected, the rotating handle 14 is rotated to make the screw groove 141 rotate in the opposite direction, and the limiting protrusion 131 disengages from the screw groove 141 to loosen the upper shell 13.

[0055] In this embodiment of the invention, the evaporator 21 is cylindrical, and the ratio of its diameter to its height is S, where 0.5 ≤ S ≤ 1, to ensure a small horizontal width of the evaporator 21. Preferably, the diameter of the evaporator 21 is P, where 80 ≤ P ≤ 100 mm. Furthermore, the ratio of the length to the height of the dual-purpose vertical snow melter is T, where 0.5 ≤ T ≤ 1, to ensure a small horizontal width of the dual-purpose vertical snow melter. The height of the dual-purpose vertical snow melter is R, where 320 ≤ R ≤ 400 mm.

[0056] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
