TECHNICAL FIELD
[0001] The utility model relates to snow melting machine technical field especially, relates to an evaporimeter and apply the snow melting machine of this evaporimeter. BACKGROUND
[0002] With the continuous improvement of people's living standards, more diversified life is pursued, so more refined, higher quality food materials are needed in life. The snow melting machine is a device that can provide a semi-solid slush-shaped beverage, which can provide users with a beverage between a liquid beverage and a solid ice block. In order to realize the production of the beverage, the existing snow melting machine mainly relies on the evaporimeter to realize refrigeration. The existing snow melting machine is usually provided with a base, the base is provided with a storage cavity for storing liquid beverage, and the evaporimeter for realizing refrigeration is arranged in the storage cavity to realize refrigeration processing of the beverage in the storage cavity. In order to ensure more uniform food production and avoid local overcooling, a stirring paddle for stirring the beverage is arranged in the storage cavity, and a driving motor for driving the stirring paddle is arranged in the base. Under the continuous stirring of the stirring paddle, the continuously cooled beverage forms a mixed snow melt. Since sufficient cooling temperature is required to form the snow melt, the existing snow melting machine is limited by the refrigeration efficiency and volume of the evaporimeter, and cannot improve the small size of the evaporimeter product, so that the existing snow melting machine is not convenient for use in general home environment.
[0003] In order to meet the needs of consumers, the existing technical solution usually reduces the volume of the evaporimeter to meet the product demand of small volume snow melting machine. However, the evaporimeter itself needs to cool the beverage, and the internal pipeline for circulating refrigerant needs to be arranged. If the volume is too small, the refrigerant circulation pipeline in the evaporimeter will not be arranged, especially the inlet pipe for providing refrigerant to the evaporimeter and the return pipe for returning refrigerant, which need to be arranged with a certain inner diameter. The evaporimeter with too small volume will not be able to arrange the inlet pipe and the return pipe. Moreover, due to the short length of the refrigerant circulation pipeline, the refrigeration cannot be effectively realized. If sufficient refrigerant circulation pipeline is arranged, the small volume evaporimeter product cannot be realized. That is to say, the existing evaporimeter has the contradiction between the refrigeration efficiency and the product volume, so it is impossible to provide the user with a truly small and convenient evaporimeter and snow melting machine, especially suitable for home use environment. SUMMARY
[0004] In view of the defects and deficiencies of the prior art, the purpose of the utility model is to provide an efficient evaporimeter and snow melting machine to solve the problems of large volume caused by low volume utilization rate of the existing evaporimeter, poor refrigeration efficiency of the one-way refrigerant circulation pipeline in the evaporimeter, and large volume and poor refrigeration efficiency of the snow melting machine caused by large volume and poor refrigeration efficiency of the evaporimeter, simple function and structural waste of the snow melting machine.
[0005] To solve the above technical problems, the application provides an evaporator, which comprises a cylindrical barrel body with a front port, an inlet pipe and a return pipe connected with the barrel body, the barrel body comprises an inner layer and an outer layer connected in a closed mode, a refrigerant flow cavity extending integrally is formed between the inner layer and the outer layer, the inlet pipe and the return pipe are communicated with the refrigerant flow cavity, and the inlet pipe extends into the refrigerant flow cavity from the rear end of the barrel body, refrigerant flows into the refrigerant flow cavity from the inlet pipe and flows out from the return pipe, so that the inner layer and the outer layer form refrigeration surfaces respectively.
[0006] According to the application, the barrel body comprises an inner layer and an outer layer, and a refrigerant flow cavity extending integrally is formed directly between the inner layer and the outer layer. Compared with the prior art evaporator which needs to be provided with a spiral refrigerant flow pipe in the barrel body, the application directly forms a refrigerant flow cavity extending integrally. Here, the extending integrally means that the refrigerant flow cavity is clamped between the inner layer and the outer layer, and there is no clear pipe or boundary limitation, so that the refrigerant can flow in the refrigerant flow cavity in a diverging manner. External refrigerant flows into the refrigerant flow cavity through the inlet pipe, and then directly diffuses in the refrigerant flow cavity and exchanges heat with food materials outside the evaporator through the inner layer and the outer layer. The refrigerant after heat exchange flows back through the return pipe. On the one hand, after the external refrigerant flows into the refrigerant flow cavity, it diffuses and exchanges heat with the food materials, which reduces the efficiency reduction caused by the continuous circulation of the refrigerant in the refrigerant flow pipe in the prior art. On the other hand, the refrigerant flow cavity is directly formed between the outer layer and the inner layer, and there is no connection structure between the refrigerant flow pipes in the prior art. When the external food materials contact the outer layer and the inner layer, all the surfaces can exchange heat, the heat exchange area is larger, the heat exchange efficiency is higher, and the heat exchange is more uniform, so that the food material preparation is more uniform. Furthermore, the evaporator simultaneously forms refrigeration surfaces for food materials on the inner layer and the outer layer. The beverage placed in the snow melting machine product using the evaporator can be cooled by the outer layer of the evaporator and injected into the space enclosed by the inner layer, and then cooled by the surface of the inner layer. In this way, the refrigeration area of the evaporator is increased, and the volume of the evaporator itself is greatly reduced, so that the snow melting machine can realize large-capacity processing in a small space. Therefore, the volume of the evaporator and the corresponding snow melting machine can be compressed to realize a small and efficient evaporator and corresponding snow melting machine product for household use. In particular, even if the refrigeration area of the evaporator is increased, the volume of the evaporator will not be greatly increased. Therefore, the high-efficiency beverage preparation demand of the existing large-capacity evaporator product and snow melting machine product can be met.
[0007] As an optional solution, the inner layer and the outer layer are arranged as annular cylinders, the front end and the rear end of the inner layer and the outer layer are closed and connected, and the interlayer of the inner layer and the outer layer forms the refrigerant flow cavity, and the inlet pipe extends into the front end of the refrigerant flow cavity from the rear end of the annular cylinder.
[0008] The inner layer and the outer layer are arranged as annular cylinders, which facilitates the production and processing of the inner layer and the outer layer. The refrigerant flow cavity can be formed between the interlayer of the inner layer and the outer layer by directly closing and connecting the front end and the rear end of the inner layer and the outer layer. The cylinder is simple and efficient to produce. Since the cylinder does not need a spiral condensation channel, the risk of damage during the production process of the condensation channel is avoided, which can cause the evaporator to fail. The inner layer and the outer layer are connected and closed, which ensures that the thickness of the refrigerant flow cavity itself is uniform, so that the cooling of the evaporator is uniform and the cooling efficiency is high. For the cylindrical evaporator, the rear end is usually fixedly connected with the snow melting machine. The inlet pipe is arranged to extend into the refrigerant flow cavity from the rear end of the cylinder, which facilitates the production and processing of the evaporator itself and the assembly of the evaporator and the snow melting machine.
[0009] As an optional solution, the length of the inlet pipe extending into the refrigerant flow cavity is not less than 1 / 2 of the depth of the refrigerant flow cavity.
[0010] In this way, the inlet pipe can extend into the front end of the refrigerant flow cavity, and the refrigerant flowing into the inlet pipe can be injected into the front end of the evaporator to exchange heat with the food outside the outer layer faster, thereby improving the refrigeration efficiency.
[0011] As an optional solution, the return pipe is arranged at the rear end of the cylinder to communicate with the refrigerant flow cavity.
[0012] For the return pipe, it is used to collect the refrigerant after heat exchange. In order to recover as much refrigerant as possible in the refrigerant flow cavity, the return pipe is arranged at the rear end of the cylinder, so that more refrigerant in the refrigerant flow cavity can flow back through the return pipe. Especially when the condensation pipe extends into the front end of the refrigerant flow cavity, the refrigerant flows back from the front end to the rear end of the refrigerant flow cavity, which realizes heat exchange with the food outside the outer layer and ensures that the refrigerant flows back through the return pipe from the rear end.
[0013] As an optional solution, the inlet pipe is provided with a plurality of branch outlets at the front end of the refrigerant flow cavity, and the outlets of the plurality of branch outlets are oriented differently.
[0014] A plurality of branch outlets are arranged at the front end outlet of the inlet pipe, in particular, the plurality of branch outlets are oriented in different directions in the refrigerant flow passage, so that the refrigerant flowing into the inlet pipe can be quickly and uniformly distributed in the refrigerant flow passage, improving the refrigeration effect of the evaporator. Both the refrigerant injected by the inlet pipe is in a high-pressure shape, and a single outlet will concentrate local injection, causing local overcooling. The arrangement of a plurality of branch outlets can reduce the pressure at a single branch outlet, avoiding local overcooling; and because the plurality of branch outlets are oriented in different directions, the inlet pipe will also be subjected to multiple reaction forces in different directions, which cancel each other out, avoiding the reliability of the inlet pipe from deteriorating when it is subjected to excessive reaction force.
[0015] As an optional solution, the inlet pipe is located on the lower side of the cylinder body; or the return pipe is located on the upper side of the cylinder body.
[0016] Generally, when the refrigerant exchanges heat with the food material, the form of the refrigerant will change, for example, from liquid to gas. By arranging the inlet pipe on the lower side of the cylinder body, the injected refrigerant exchanges heat with the food material on the lower side, ensuring that the food material located on the bottom side of the evaporator can also be efficiently cooled and processed; as the form of the refrigerant continuously changes and moves upward, it can further exchange heat with the food material located on the outer periphery of the evaporator, achieving the processing of cooking the food material. Such an arrangement makes the refrigeration efficiency of the evaporator higher and more uniform, especially ensuring that the food material located on the bottom of the evaporator can also be fully cooled and processed. When the refrigerant completes heat exchange in the refrigerant flow passage, it usually changes from liquid to gas due to the decrease in density, and the refrigerant concentrates on the upper part. By arranging the return pipe on the upper side of the cylinder body, more refrigerant can be ensured to return through the return pipe. In particular, by arranging the inlet pipe on the lower side of the cylinder body and the return pipe on the upper side of the cylinder body, the refrigerant that has not yet completed heat exchange usually cannot directly return through the return pipe, making the heat exchange of the refrigerant more sufficient, thereby improving the refrigeration efficiency of the evaporator. In addition, the arrangement of the inlet pipe and the return pipe on the lower side and the upper side, respectively, also ensures the balance of the structure of the cylindrical evaporator, avoiding local stress concentration.
[0017] Correspondingly, the application also provides a high-efficiency snow melting machine, comprising a shell, a refrigeration assembly and a power assembly arranged in the shell, and a processing module arranged on the shell, wherein the processing module comprises a stirring bin, an evaporator and a stirring paddle arranged in the stirring bin, the evaporator adopts the evaporator in the foregoing technical solution, the rear end of the evaporator is fixedly connected with the stirring bin, the refrigerant flow-through cavity is communicated with the refrigeration assembly through the inlet pipe and the return pipe, the outer layer forms a refrigeration cavity in the stirring bin, the inner layer forms an inner refrigeration cavity in the evaporator and communicated with the refrigeration cavity, and the stirring paddle comprises an outer stirring paddle and an inner stirring paddle, the outer stirring paddle is arranged on the outer side of the cylinder body, and the inner stirring paddle is arranged in the inner refrigeration cavity.
[0018] Since the evaporator forms an integrated refrigerant flow-through cavity through the outer layer and the inner layer, the refrigeration area of the outer layer of the evaporator is larger and the refrigeration efficiency is higher, so that the small evaporator and stirring bin can meet the cooling processing requirements of food materials. Since the effective refrigeration area of the outer layer is increased, the effective utilization rate of the evaporator is improved, so that the requirements of food material processing can be met under the premise of small volume stirring bin and evaporator, and ultimately a snow melting machine product with small size, convenient operation and high processing efficiency is provided for users to better meet the requirements of home use environment. Of course, for a general snow melting machine product using this scheme, since the refrigeration efficiency of the evaporator itself is improved, the time of single cooking processing of the snow melting machine can be compressed, the requirements of commercial rapid processing can be better met, the heat loss is small, the refrigeration efficiency is high, and the purpose of energy saving and consumption reduction can be achieved. Furthermore, the outer layer of the evaporator forms a refrigeration cavity in the stirring bin for cooling processing of food materials, and further, the inner layer forms an inner refrigeration cavity in the evaporator and communicated with the refrigeration cavity. The inner layer and the outer layer can simultaneously cool the food materials, increase the cooling area of the evaporator, and improve the cooling efficiency of the evaporator, so that the small evaporator and stirring bin can meet the cooling processing requirements of food materials. Since the inner refrigeration cavity is formed in the evaporator to accommodate food materials, the space volume occupied by the evaporator in the stirring bin is reduced, thereby greatly improving the space volume utilization rate of the stirring bin of the snow melting machine itself, improving the actual use capacity of the stirring bin without increasing the volume of the stirring bin, realizing the requirements of large-capacity food material processing, and ultimately providing a snow melting machine product with small size, convenient operation and high processing efficiency for users, which can better meet the requirements of home use environment. Of course, the snow melting machine product using this way is also suitable for large volume and large capacity product requirements, and since the refrigeration efficiency of the snow melting machine itself is improved, the capacity of single processing of the snow melting machine can be improved, the time of single food material processing of the snow melting machine can be compressed, and the requirements of commercial rapid processing can be better met.
[0019] As an optional solution, the front end of the inner stirring paddle is provided with a driving section, the outer stirring paddle is connected with the inner stirring paddle through the driving section, and the inner stirring paddle drives the outer stirring paddle to rotate.
[0020] The driving section is directly arranged at the front end of the inner stirring paddle, and the outer stirring paddle is directly connected with the inner stirring paddle through the driving section, so that the outer stirring paddle can be driven at the same time when the inner stirring paddle is driven, and a plurality of driving modules are avoided when the inner stirring paddle and the outer stirring paddle are driven respectively. The outer stirring paddle and the inner stirring paddle are directly connected, and the synchronous rotation of the outer stirring paddle and the inner stirring paddle is more convenient to set, so that the inner stirring paddle can better mix the food materials in the inner refrigeration cavity and the stirring barrel.
[0021] As an optional solution, the rear end of the barrel body is further provided with a rear end port communicating with the inner refrigeration cavity and the refrigeration cavity.
[0022] The barrel body is arranged in a ring shape, the inner stirring paddle and the outer stirring paddle can be conveniently arranged as rotating members concentric with the ring-shaped barrel body, and the gap between the inner stirring paddle and the outer stirring paddle and the barrel body is also conveniently reduced, so that the inner stirring paddle and the outer stirring paddle can scrape the food materials on the surface of the barrel body more thoroughly, and the food materials on the surface of the barrel body are prevented from being excessively cooled. The barrel body is directly provided with openings at the front and rear ends, the food materials can flow from one end of the barrel body to the other end, flow in the barrel body, realize the food material, and also promote the flow circulation of the food materials in the stirring bin, and further improve the uniformity of the food materials being cooled and processed.
[0023] As an optional solution, the processing module further comprises an NTC module arranged at the rear end of the stirring bin; or the stirring bin comprises a bin body with an upper opening and a bin cover, the bin cover covers the opening, and the bin cover is provided with an NTC module extending into the interior of the bin body.
[0024] Due to the further formation of the inner refrigeration cavity inside the barrel, the space occupied by the evaporator is reduced, but due to the reduction in the volume of the evaporator, it will be inconvenient to install the components directly installed on the evaporator in the original scheme. In order to improve the reliability of the snow melting machine processing, the NTC module is arranged at the rear end of the stirring bin, compared with the prior art, although the NTC is directly arranged at the rear end of the stirring bin, but due to the inner refrigeration cavity, the food materials can flow more uniformly in the stirring bin, thereby also enabling the temperature of the food materials in the stirring bin to be accurately detected at the rear end. According to the structure of the stirring bin, the NTC can also be arranged on the bin cover, when the bin cover is closed on the bin body, the NTC module extends into the interior of the stirring bin. The basis of such arrangement is that the evaporator has higher refrigeration efficiency and faster refrigeration, and the hollow evaporator also brings more uniform food material flow, so that according to the structural characteristics of the stirring bin, the corresponding NTC module can be arranged at different positions.

[0034] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to explain the relevant application, but not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0036] As Figures 1-7As shown, the utility model discloses an evaporator and use high -efficient snow -melt machine product, the evaporator includes cylinder, import pipe 31 and backflow pipe 32, the cylinder includes outer layer 11 and inner layer 12, the outer layer 11 and inner layer 12 closed connection, so that the outer layer 11 and inner layer 12 between form the refrigerant flow cavity 13 of integral extension, import pipe 31 and backflow pipe 32 respectively with refrigerant flow cavity 13 communicate, wherein, the refrigerant of outside is injected into refrigerant flow cavity 13 through import pipe 31, and flows out through backflow pipe 32. Since the refrigerant is injected between the sandwich of outer layer 11 and inner layer 12, so that the outer layer 11 and inner layer 12 are directly contacted with the refrigerant, and then the outer surface of the outer layer 11 and inner layer 12 contacted with the outside simultaneously forms the refrigeration surface of food cooling. In the prior art, the evaporator is provided with a spiral condensing channel in the form of a spiral pipe on the inner surface of the cylinder. The refrigerant flows into the spiral condensing channel from the beginning, flows through sequentially inside, and flows out from the end. The refrigerant can only flow through sequentially in the spiral condensing channel, so that the surface at the front end of the spiral condensing channel is always at the front end of the input refrigerant, and is at a lower temperature range. The surface at the rear end of the spiral condensing channel is at a higher temperature range because the refrigerant has undergone heat exchange. Furthermore, there is a structural gap between the adjacent pipes of the spiral condensing channel. The structural gap cannot be directly contacted with the refrigerant, and the refrigeration efficiency is poor or cannot be realized. Finally, the refrigeration efficiency of the evaporator is poor, and the refrigeration is uneven. The evaporator of the present application directly forms an integral refrigerant flow cavity by the outer layer and the inner layer. The refrigerant flow cavity does not have a pipe structure inside to block the refrigerant flow. When the external refrigerant is injected into the refrigerant flow cavity, it can quickly disperse to each area in the refrigerant flow cavity and exchange heat with the food material outside the evaporator through the inner layer and the outer layer. On the one hand, the external refrigerant quickly spreads after being injected into the refrigerant flow cavity, reducing the efficiency reduction caused by the circulation of the refrigerant in the pipe. On the other hand, the refrigerant flow cavity is directly formed between the outer layer and the inner layer, and the surfaces of the outer layer and the inner layer form a complete refrigeration surface without non-refrigeration structural gaps. The refrigeration area is larger, the refrigeration is more uniform, and the refrigeration efficiency is higher. Furthermore, the outer layer and the inner layer of the evaporator of the present application simultaneously form a refrigeration surface for cooling food material. Therefore, when the food material is cooled and processed, the food material can be cooled by the outer surface, and can also flow into the interior of the evaporator to exchange heat with the inner layer. Compared with the evaporator of the prior art, the evaporator of the present application further increases the refrigeration area of the inner layer, the refrigeration area is larger, and the refrigeration efficiency is higher. In particular, since the interior of the evaporator can also be used to accommodate food material, the structural space occupied by the evaporator itself is reduced. Therefore, the space utilization rate of the snow-melt machine product using the evaporator of the present application is greatly improved.Therefore, the application also provides a high-efficiency snow melting machine, which comprises a shell 4 and a refrigeration assembly, a power assembly and a processing module. Generally, the refrigeration assembly and the power assembly are arranged in the shell 4, and the processing module is arranged in the shell 4. The processing module comprises a stirring bin 42, an evaporator and a stirring paddle. The evaporator and the stirring paddle are arranged in the stirring bin 42. The rear end of the evaporator is fixedly connected with the stirring bin 42. The condensation flow-through cavity 13 is communicated with the refrigeration assembly through the inlet pipe 31 and the return pipe 32. The outer layer 11 forms a refrigeration cavity 43 in the stirring bin 42. The inner layer 12 forms an inner refrigeration cavity 2 in the stirring bin 42. The inner refrigeration cavity 2 is communicated with the refrigeration cavity 43. The food placed in the stirring bin 42 flows between the refrigeration cavity 43 and the inner refrigeration cavity 2. The stirring paddle comprises an outer stirring paddle 6 located outside the cylinder body 1 of the evaporator and an inner stirring paddle 5 located inside the cylinder body 1. On the basis of the evaporator forming the refrigerant flow-through cavity, the outer layer and the inner layer simultaneously form refrigeration surfaces. The inner layer forms an inner refrigeration cavity communicated with the refrigeration cavity of the stirring bin. When the food is placed in the stirring bin, the food can contact the refrigeration surface of the outer layer and the refrigeration surface of the inner layer. The food can also flow between the inner refrigeration cavity and the refrigeration cavity. Therefore, the refrigeration area of the evaporator is greatly improved, the refrigeration efficiency is correspondingly improved, and the processing time of the snow melting machine is greatly reduced. Alternatively, due to the improvement of the refrigeration efficiency of the evaporator, the volume of the snow melting machine product can be reduced by reducing the volume of the evaporator, so as to realize the purpose of a light and small product. Further, since the inner refrigeration cavity is formed in the evaporator to accommodate food, the space occupied by the evaporator in the stirring bin is reduced, generally only having the thickness of the evaporator itself. Compared with the existing evaporator having an assembly space inside, the space utilization of the snow melting machine of the application is improved. Under the same stirring bin volume, the snow melting machine of the application has a larger actual processing capacity. Alternatively, under the same nominal capacity, the snow melting machine of the application has a smaller volume.
[0037] Embodiment one.
[0038] As the first embodiment of the evaporator described in the application, as Figure 1 , Figure 2As shown, in particular, the evaporator includes a cylinder body 1, an inlet pipe 31 and a return pipe 32 connected to the cylinder body 1, the cylinder body 1 includes an outer layer 11 and an inner layer 12, the outer layer 11 and the inner layer 12 are both provided in an annular cylindrical shape, and the front end and the rear end of the outer layer 11 and the inner layer 12 are respectively closed and connected to form a refrigerant flow cavity 13 by the interlayer of the outer layer 11 and the inner layer 12, the outer layer 11 and the inner layer 12 are preferably made of plate-shaped stainless steel, so that the surfaces of the outer layer 11 and the inner layer 12 located in the refrigerant flow cavity 13 are not provided with barrier structures, therefore, the refrigerant flow cavity 13 extends integrally in the cylinder body 1, thereby, when the external refrigerant is injected into the refrigerant flow cavity 13 by the inlet pipe 31, it can be uniformly distributed and dispersed in the refrigerant flow cavity 13 without obstruction, and will not flow only in one direction. The rear end of the cylinder body 1 is also provided with a mounting bracket 100 fixedly connected to the outside, which is fixedly connected to the corresponding product by the mounting bracket 100.
[0039] The inside of the outer layer 11 and the inner layer 12 is in contact with the refrigerant flow cavity 13, so that the outer surface of the outer layer 11 and the inner layer 12 can form a refrigeration surface in contact with the food at the same time, thereby, compared with the prior art, the evaporator of the present application forms an internal refrigeration cavity 2 in the inside of the cylinder body 1, which fills the food outside the evaporator, that is, can surround the outside of the outer layer 11, and can also be injected into the internal refrigeration cavity 2 to contact the inner layer 12, thereby making the space volume occupied by the evaporator itself only the thickness between the outer layer 11 and the inner layer 12, and the space utilization rate is greatly improved.
[0040] The inlet pipe 31 is located at the lower side of the cylinder body 1 and extends into the refrigerant flow cavity 13 from the rear end of the cylinder body 1, and the inlet pipe 31 extends to the front end of the refrigerant flow cavity 13. Among them, the length of the inlet pipe 31 extending into the refrigerant flow cavity 13 is L1, and the length of the refrigerant flow cavity 13 in the axial direction is L, wherein L1 / L≥1 / 2. Thus, the inlet pipe 31 extends from the rear end to the front end of the refrigerant flow cavity 13. When the external refrigerant is injected into the refrigerant flow cavity 13 by the inlet pipe 31, the refrigerant can more directly and quickly reach the front end of the evaporator to cool the food located at the front end of the evaporator.
[0041] The return pipe 32 is located at the upper side of the cylinder body, and preferably, the return pipe 32 is connected with the rear end of the refrigerant flow cavity 13 and does not extend into the refrigerant flow cavity 13. Of course, in order to ensure the stable and reliable connection of the return pipe 32 with the cylinder body 1, a small part of the return pipe 32 will extend into the refrigerant flow cavity 13 in the actual production process, which is also within the protection direction of the present application. In this way, the inlet pipe 31 extends to the front end of the refrigerant flow cavity 13 to inject refrigerant into the front end of the refrigerant flow cavity 13, and the refrigerant is quickly and uniformly dispersed in the refrigerant flow cavity 13, exchanges heat with the food materials outside the cylinder body 1, and gradually returns to the rear end, and then finally returns to the external refrigeration assembly through the return pipe 32 at the rear end. The return pipe 32 at the rear end enables the refrigerant to be more uniformly dispersed in the refrigerant flow cavity, and also enables the refrigerant after heat exchange to be more thoroughly returned and recovered by the return pipe, avoiding the refrigerant remaining in the refrigerant flow cavity and affecting the refrigeration efficiency.
[0042] Preferably, the inlet pipe 31 extending into the front end of the refrigerant flow cavity 13 has a plurality of branch outlets, and the outlets of the plurality of branch outlets in the refrigerant flow cavity 13 are oriented differently. That is, the plurality of branch outlets are dispersed in various directions in the refrigerant flow cavity 13, for example, the front end of the inlet pipe 31 is provided with a 4-way pipe, one interface of which communicates with the inlet of the inlet pipe 31, and the other three interfaces are vertically arranged to face the front end, left side and right side of the refrigerant flow cavity 13. Of course, it should be noted that since the refrigerant flow cavity 13 is annular, the outlets on the left side and the right side are also annular and are arranged circumferentially to the left and right, respectively. Preferably, the outlet diameter of the plurality of branch outlets is smaller than the inner diameter of the inlet pipe 31, so that the refrigerant with pressure outside can flow out through different branches. In this way, on the one hand, it ensures that the refrigerant can be more quickly and uniformly dispersed in the refrigerant flow cavity 13, so that the evaporator can more quickly, uniformly and efficiently cool the food materials outside the outer layer 11; on the other hand, the refrigerant injected by the inlet pipe 31 is usually in a high-pressure state, and if it is discharged through a single outlet, it will be ejected through a single outlet, which will exert a large reaction force on the inlet pipe 31, affecting the structural stability of the inlet pipe 31. By arranging a plurality of branch outlets, the outlet pressure of each branch outlet is reduced, and by arranging the branch outlets in opposite directions, the reaction forces of the opposite branch outlets are offset, further reducing the influence of the refrigerant pressure on the inlet pipe 31.
[0043] The refrigerant flow passage is formed integrally by the inner layer and the outer layer of the cylinder body, so that the external refrigerant can be quickly dispersed in the refrigerant flow passage after being injected into the refrigerant flow passage, the circulation time of the refrigerant in the spiral inlet pipe is reduced, and the cooling speed is faster; since the refrigerant can quickly fill the entire refrigerant flow passage, the entire surface of the outer surface of the cylinder body in contact with the food material can be quickly cooled, the contact area is increased, the cooling efficiency is higher, and the non-cooling surface formed between the walls of the spiral inlet pipe in the prior art is reduced, the effective cooling area is increased, and the cooling efficiency of the evaporator is ensured. The inner cooling cavity for accommodating the food material is formed by the inner layer, which further increases the cooling area of the evaporator and reduces the space volume occupied by the evaporator, so that the cooling efficiency of the evaporator is improved, and the space utilization is greatly improved. In this way, high-speed and efficient cooling is realized, and the space utilization of a product such as a snow melting machine using the evaporator is improved, so that the food material can be cooled faster and more under the premise of the same processing capacity.
[0044] It can be understood that the inner layer and the outer layer can also be provided in different shapes according to different structural characteristics, for example, the inner layer can also be adjusted to be elliptical or the like; or the inner layer is also provided with a local groove structure for fixing the inlet pipe and the like.

[0051] Embodiment two.
[0052] As the first embodiment of the snow melting machine using the efficient evaporator described in the present application, as shown in Figures 3-5 the embodiment, compared with embodiment one, the embodiment specifically provides a snow melting machine product using the foregoing technical solution evaporator. It should be noted that the specifically described embodiment one embodiment two are not completely independent of each other, but only for specifically illustrating two preferred technical solutions, and the technical features and technical solutions of the two embodiments are common and can be used for each other.
[0053] Specifically, as shown in Figures 3-5 the snow melting machine includes a shell 4, a refrigeration assembly, a power assembly and a processing module. Preferably, the refrigeration assembly and the power assembly are arranged in the shell 4, and the processing module is arranged on the shell 4. The processing module includes a stirring bin 42, an evaporator and a stirring paddle, the evaporator and the stirring paddle are arranged in the stirring bin 42, and the evaporator adopts the evaporator structure described in the foregoing technical solution.
[0054] The rear end of the evaporator is fixedly connected with the stirring bin 42 by a mounting bracket 100, the evaporator includes an outer layer 11 and an inner layer 12, the outer layer 11 and the inner layer 12 are sealingly connected and form a closed refrigerant flow passage 13 inside, the refrigerant flow passage 13 is clamped by the outer layer 11 and the inner layer 12, the refrigerant flow passage 13 extends integrally from the rear end to the front end, and no blocking structure is arranged to block the refrigerant. The refrigerant flow passage 13 is in communication with the refrigeration assembly through an inlet pipe 31 and a return pipe 32, refrigerant is injected into the refrigerant flow passage 13 through the inlet pipe 31, and after heat exchange with external food materials in the refrigerant flow passage 13, the refrigerant is returned to the refrigeration assembly through the return pipe 32. Preferably, the inlet pipe 31 is located at the bottom of the cylinder body 1 and extends into the refrigerant flow passage 13; the return pipe is fixedly located at the top of the cylinder body and is directly connected to the rear end of the cylinder body 1.
[0055] The evaporator is arranged in the stirring bin 42, and the food materials are put into the stirring bin 42 through the upper end opening of the stirring bin 42. The upper end opening of the stirring bin 42 is also provided with a bin cover 44, which blocks and closes the opening of the stirring bin 42. Thus, the outer layer of the evaporator forms a refrigeration cavity 43 with the stirring bin 42, and the inner layer of the evaporator forms an inner refrigeration cavity 2 which communicates with the refrigeration cavity 43. When the food materials are put into the stirring bin 42, the food materials flow between the refrigeration cavity 43 and the inner refrigeration cavity 2. The front end of the stirring bin 42 is also provided with a discharge opening 45 and a faucet 46. By operating the faucet 46, the discharge opening 45 is opened, and the food materials in the refrigeration cavity 43 are discharged through the discharge opening 45.
[0056] In order to better realize the flow of food materials in the refrigeration cavity 43 and the inner refrigeration cavity 2, the stirring paddle includes an outer stirring paddle 6 located in the refrigeration cavity 43 and an inner stirring paddle 5 located in the inner refrigeration cavity 2. The power assembly is provided with a transmission shaft 41 which passes through the stirring bin 42 and the rear end of the evaporator.

The outer stirring paddle 6 includes a transmission section 61, front blades 62, outer blades 63, and an outer connecting frame 64. Preferably, the outer stirring paddle 6 is power-connected with the driving section 53 of the inner stirring paddle 5 through the transmission section 61, so that the inner stirring paddle 5 drives the outer stirring paddle 6 to rotate synchronously. The front blades 62 are arranged at the front end of the cylinder body 1, and the outer blades 63 are arranged on the outer side of the cylinder body 1.
[0057] In order to ensure the stable and reliable refrigeration of the snow melting machine, the temperature of the food materials in the stirring bin needs to be monitored to ensure that the food materials reach the processing effect and stop cooling, so as to avoid that the food materials are excessively cooled and affect the processing effect of the food materials. Preferably, the cylinder body 1 is also provided with an NTC module 23 which is located at the rear end of the inner refrigeration cavity 21, is fixed on the rear end wall of the cylinder body 1, and is signal-connected with the control module of the snow melting machine to feed back the detected temperature of the food materials in the stirring bin to the snow melting machine.
[0058] Compared with the prior art, the evaporator described in the application forms an integrally extended refrigerant flow passage inside, so that the refrigerant injected into the refrigerant flow passage can be quickly and uniformly dispersed in the refrigerant flow passage, thereby quickly and efficiently cooling the food. Further, the evaporator is formed by an outer layer to form a refrigeration cavity, and an inner layer to form an inner refrigeration cavity, the refrigeration cavity and the inner refrigeration cavity are in communication with each other, so that the food in the stirring bin can enter the inside of the evaporator, so that the space occupied by the evaporator in the stirring bin can be greatly reduced, and the space volume utilization rate of the stirring bin can be greatly improved. And even if the refrigeration area of the evaporator is further increased, the volume of the evaporator will not be increased too much, so that the refrigeration speed of the snow melting machine is faster, the refrigeration efficiency is higher, and the processing demand of larger volume snow melting machine can also be met. In particular, due to the improvement of the space utilization rate and the refrigeration efficiency of the evaporator, even if a small volume stirring bin structure is set, the evaporator can also place enough refrigeration area to realize refrigeration processing, so as to ensure that the small volume snow melting machine can also meet the demand of refrigeration processing, thereby realizing the light, small and efficient snow melting machine product.
[0059] It can be understood that the outer stirring paddle and the inner stirring paddle can be provided as an integrated structure, including integrally connected outer stirring blades and inner stirring blades, the outer stirring blades and the inner stirring blades clamping the barrel body, so that the outer stirring blades are attached to the outer layer, and the inner stirring blades are located in the inner refrigeration cavity.
[0060] It can be understood that the outer stirring paddle and the inner stirring paddle are respectively and powerfully connected. For example, the inner stirring paddle is driven and connected by a central transmission shaft, and the rear end of the stirring bin is also provided with a power structure for driving the outer stirring paddle. The outer stirring paddle and the inner stirring paddle are respectively driven by the power assembly, so that the outer stirring paddle and the inner stirring paddle can realize different rotation requirements according to different states. For example, during mixing and stirring, one of the outer stirring paddle and the inner stirring paddle forwards the material, and the other one forwards the material, so that the material circulates between the outer layer, the inner layer and the two sides, improving the refrigeration efficiency of the snow melting machine. When the snow melting machine discharges the material after processing, the outer stirring paddle and the inner stirring paddle can simultaneously push the material from the rear end to the front end to improve the discharging efficiency of the material.
[0061] It can be understood that the NTC module can also be directly arranged at the rear end of the stirring bin, or arranged on the cover of the stirring bin. When the cover closes the opening of the stirring bin, the NTC module extends into the refrigeration cavity.
