Description

Technical Field

[0001] The present invention relates to the technical field of snow melting machines, in particular to a snow melting machine which is easy to use. 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] The snow melters of the prior art use the evaporator to achieve heat exchange in order to cool the food. In order to improve the refrigeration efficiency of the snow melters, it is necessary to increase the cooling area of the evaporator. In order to increase the cooling area, the existing evaporator needs to increase the volume of the evaporator. However, when the volume of the evaporator increases, it will occupy the space volume in the mixing drum, which will reduce the volume utilization of the snow melter. At the same time, since the evaporator needs to be in contact with the food to achieve cooling, if the snow melter directly reduces the volume of each module, the contact area of the evaporator will be reduced, the cooling efficiency will be reduced, and even due to the influence of the cooling heat exchange and the external ambient temperature, the snow melter will not be able to effectively complete the processing. Therefore, the existing snow melters cannot truly achieve a small size, convenient use and storage, and the existing snow melters cannot meet the needs of 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 easy-to-use snow melter to solve the technical problems of insufficient evaporator cooling area, low volume utilization rate of the mixing drum, excessive size of the snow melter, poor cooling efficiency, and inconvenience caused by simple functions of the snow melter.

[0005] In order to solve the above technical problems, the present invention provides an easy-to-use 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 includes a stirring drum, an evaporator and a stirring paddle arranged in the stirring drum, the evaporator includes a cylinder with a front end opening, a spiral condensation channel, a condensation inlet and a condensation outlet connected to the spiral condensation channel, the cylinder includes an inner cylinder and an outer cylinder arranged outside the inner cylinder, the outer cylinder and the inner cylinder are concentric rings, the inner cylinder and the outer cylinder are closed and connected at the front end to form an internal space to accommodate the spiral condensation channel, the spiral condensation channel is simultaneously fitted with the inner cylinder and the outer cylinder, the outside of the outer cylinder forms a condensation chamber located in the stirring drum, and the inside of the inner cylinder forms an inner condensation chamber connected to the condensation chamber.

[0006] According to the technical solution described in the present application, the snow melter includes an evaporator disposed within the mixing drum. Compared to prior art evaporators, which suffer from a conflict between cooling area and volume, i.e., they cannot achieve both a small volume and a large cooling area, the evaporator in the present application comprises an inner drum and an outer drum sleeved over the inner drum. The front ends of the outer and inner drums are sealed and connected to form an interior space. A spiral condensation channel is disposed within the interior space, and the spiral condensation channel is in contact with both the outer and inner drums. Furthermore, the front end of the inner drum is provided with an opening, and an inner condensation chamber is formed within the inner drum. This allows both the outer and inner walls of the outer drum to form a cooling area in contact with the food. Compared to prior art snow melters that only provide a cooling surface on the outer surface of the evaporator, the present solution not only retains the cooling area provided by the outer surface of the drum, but also increases the cooling area provided by the inner surface of the inner drum. Consequently, both the outer and inner surfaces of the evaporator's outer drum can cool the food, significantly improving the cooling efficiency of the snow melter. At the same time, since both sides of the spiral condensation pipe can simultaneously exchange heat with the food, heat loss on the other side during one-sided heat exchange is avoided, and the cooling efficiency of the snow melter is further increased. In addition, since an inner condensation chamber is formed inside the evaporator, the food in the mixing drum can enter the inner condensation chamber for cooling processing, and the volume of the space occupied by the evaporator itself is greatly reduced, usually only the thickness of the outer and inner drums themselves. Even if the area of the outer and inner drums is further increased, thereby increasing the cooling area of the snow melter, the volume occupied by the evaporator will not be increased too much, thereby greatly improving the space utilization of the snow melter. In addition, since the cooling area of the evaporator is increased without increasing the volume occupied by the evaporator, the snow melter can be set to be more compact and lightweight, convenient for users to store, and more suitable for use in a home environment.

[0007] As an optional solution, the stirring paddle includes an inner stirring paddle located in the inner condensing chamber and an outer stirring paddle sleeved on the outside of the outer cylinder.

[0008] At the same time, an inner stirring paddle is set in the inner condensing chamber, and an outer stirring paddle is installed on the outside of the outer cylinder. The ingredients in the mixing cylinder can be stirred at the same time. The inner stirring paddle can also be used to roll and push to mix the ingredients in the inner condensing chamber with the ingredients in the entire condensing chamber, making the processing of the snow melter more uniform and avoiding local overcooling. The embedded inner stirring paddle and the directly installed outer stirring paddle can also fit closely with the inner and outer cylinders as much as possible to push away ingredients close to the outer or inner cylinders, so as to prevent the ingredients from being overcooled and frozen due to prolonged contact with the outer or inner cylinders, which would affect the normal processing of the snow melter.

[0009] 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.

[0010] A driving section is directly provided at the front end of the inner stirring paddle, and the driving section is connected to the outer stirring paddle by power. On the one hand, a single power source can be used to simultaneously drive the inner and outer stirring paddles, thus avoiding the increased cost and complicated structure caused by the need to separately provide driving units for the outer and inner stirring paddles. On the other hand, the outer stirring paddle is directly driven by the inner stirring paddle, and the outer and inner stirring paddles rotate synchronously, making it convenient to evenly mix and stir the ingredients in the condensation chamber and the inner condensation chamber. Furthermore, a mixing and stirring device can be provided at the power connection between the outer and inner stirring paddles to better mix and stir the ingredients in the condensation chamber and the inner condensation chamber.

[0011] As an optional solution, a front stirring blade is further provided at the front end of the external stirring paddle, and the front stirring blade is axially located at the front end of the evaporator.

[0012] Although an inner condensation chamber is formed inside the inner cylinder of the evaporator, which improves the space utilization of the snow melter, the ingredients placed in the mixing drum are mainly concentrated in the condensation chamber, and more of them need the outer stirring paddle to roll, mix and stir. A front stirring blade is further provided at the front end of the outer stirring paddle. On the one hand, the front stirring blade can occupy more stirring space in the mixing drum, avoiding the existence of dead corners of mixing and stirring in the mixing drum, making the stirring more uniform, and also avoiding the inability of ingredients in the dead corners to be mixed and condensed; on the other hand, the front stirring blade is located at the connection between the inner stirring paddle and the outer stirring paddle, which can more fully mix and stir the ingredients pushed by the inner stirring paddle and the outer stirring paddle, so that the ingredients in the inner condensation chamber and the condensation chamber are more fully mixed, thereby improving the processing effect of the snow melter.

[0013] As an optional solution, a transmission shaft connected to the power assembly is provided at the rear end of the inner stirring paddle, and a through hole for the transmission shaft to pass through is provided at the center of the rear end wall of the inner cylinder.

[0014] Because the outer cylinder is sleeved onto the outer portion of the inner cylinder, the evaporator is typically configured in an annular cylindrical shape, and the inner stirring paddle rotates within the inner condensing chamber of the cylinder. A through hole for the drive shaft of the inner stirring paddle is provided directly in the center of the rear end wall of the inner cylinder, thereby facilitating the driving of the inner stirring paddle. Furthermore, a sealing structure can be conveniently provided directly at the through hole to prevent the food in the mixing cylinder from leaking out through the through hole. Furthermore, the outer stirring paddle can be driven by the inner stirring paddle.

[0015] As an optional solution, the evaporator further includes a shaft seal arranged at the through hole, and the shaft seal sleeve is arranged outside the transmission shaft.

[0016] Adding a shaft seal can further improve the sealing performance between the transmission shaft and the mixing drum, prevent the food in the mixing drum from leaking out from the connection between the transmission shaft and the through hole, and ensure the safe and reliable operation of the snow melter.

[0017] As an optional solution, a spiral condensation tube is provided between the inner tube and the outer tube, and the spiral condensation tube is respectively attached to the outer tube and the inner tube, and the spiral condensation tube forms the spiral condensation channel.

[0018] A spiral condenser is directly arranged between the outer cylinder and the inner cylinder, and the spiral condenser is directly fitted with the outer cylinder and the inner cylinder. On the one hand, the refrigerant in the spiral condenser can exchange heat with the external food more directly, thereby improving the refrigeration efficiency; on the other hand, the directly fitted outer cylinder, spiral condenser and inner cylinder further reduce the volume occupied by the evaporator itself in the mixing cylinder, thereby better improving the space volume utilization rate of the snow melter.

[0019] As an optional solution, the length of the outer cylinder is greater than that of the inner cylinder, so that a built-in cavity is formed between the rear end walls of the outer cylinder and the inner cylinder, and the condensation inlet and the condensation outlet are arranged inside the built-in cavity.

[0020] With respect to the evaporator, although the internal condensation chamber can be used to reduce the space occupied by the evaporator and improve the space utilization of the snow melter, the snow melter and evaporator still require external connection structures. For example, the spiral condensation channel requires the condensation inlet and condensation outlet to be connected to the refrigeration component. Therefore, the length of the outer cylinder is set to be greater than the length of the inner cylinder. Since the outer cylinder and the inner cylinder are closed and connected at the front end, the outer cylinder forms an internal space at the rear end of the inner cylinder. This internal space can be used to install the condensation inlet and condensation outlet, as well as the connection structure between the condensation inlet and condensation outlet and the refrigeration component. The transmission connection structure of the internal stirring paddle and the control module of the evaporator can also be provided. Without increasing the volume, the space utilization of the evaporator is maximized.

[0021] As an optional solution, the evaporator further includes a condensation inlet pipe clamped in the inner space of the outer cylinder and the inner cylinder, and the condensation inlet pipe extends into the front end of the inner space to communicate with the spiral condensation channel.

[0022] A condensation inlet pipe is further provided between the outer cylinder and the inner cylinder, and the condensation agent is directly delivered to the front end of the spiral condensation channel by the condensation inlet pipe, so that the condensation agent input by the refrigeration component is fully in contact with the food at the front end of the evaporator, and gradually flows to the rear end of the evaporator, and finally flows back into the refrigeration component from the condensation outlet at the end, so as to achieve more efficient refrigeration of the evaporator.

[0023] As an optional solution, the outer wall of the inner cylinder is provided with a spiral groove, the inner cylinder is fitted with the inner wall of the outer cylinder, and the spiral groove forms the spiral condensation channel; or, the inner wall of the outer cylinder is provided with a spiral groove, the outer wall of the inner cylinder is fitted with the outer cylinder, and the spiral groove forms the spiral condensation channel; or, the inner wall of the outer cylinder is provided with an inner spiral groove, the outer wall of the inner cylinder 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.

[0024] A spiral groove is directly provided on the outer cylinder or the inner cylinder, and the spiral groove is used to form a spiral condensation channel of the evaporator. Whether it is the outer cylinder or the inner cylinder, it is possible to more directly achieve sufficient heat of the refrigerant and food in the spiral condensation channel; at the same time, a spiral groove is directly provided on the outer cylinder or the inner cylinder to form the spiral condensation channel, and a separate spiral condensation tube is no longer required, which reduces the number of accessories, reduces the cost of the snow melter, and can further compress the space volume occupied by the evaporator to further improve the space utilization of the snow melter.

The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise.

[0035] like Figure 1-7 As shown, the present invention discloses a convenient snow melter, which includes a housing 1 and a refrigeration assembly (not shown) located within the housing, a power assembly 11, and a processing module. The processing module is disposed above the housing 1 and includes a mixing drum 2, an evaporator 3, and stirring paddles. The stirring paddles include an outer stirring paddle 4 and an inner stirring paddle 5. The evaporator 3, the outer stirring paddle 4, and the inner stirring paddle 5 are all disposed within the mixing drum 2, which defines a condensation chamber 22. The evaporator 3 includes a cylindrical body with a front opening, a spiral condensation channel, a condensation inlet 36 communicating with the spiral condensation channel, and a condensation outlet 37. The cylinder body includes an outer cylinder 31 and an inner cylinder 32, the outer cylinder 31 is sleeved on the outside of the inner cylinder 32, and the front ends of the outer cylinder 31 and the inner cylinder 32 are closed and connected to form an internal space 35 between the outer cylinder 31 and the inner cylinder 32, the spiral condensation channel is located in the internal space 35, and at the same time fits with the inner side wall of the outer cylinder 31 and the outer side wall of the inner cylinder 32, so that the outer surfaces of the outer cylinder 31 and the inner cylinder 32 are formed with cooling surfaces that contact the food, and an inner condensation chamber 6 is formed inside the inner cylinder 32 to communicate with the condensation chamber 22. Compared to the prior art, which forms a cooling surface only on the outer surface of the evaporator, the present invention utilizes both the outer and inner cylinders of the evaporator to form a cooling surface, thereby increasing the cooling area and improving the cooling efficiency of the snow melter without increasing the volume of the space. Furthermore, the cylinder forms an inner condensation chamber within the inner cylinder, through which the food in the mixing drum can flow, significantly reducing the volume occupied by the evaporator within the mixing drum and improving the space utilization of the mixing drum. Thus, a small mixing drum can be used to process food of the rated volume, thereby enabling the snow melter to be lightweight and compact, convenient for user operation and storage, and easy to use, making it particularly suitable for use in a home environment. Of course, even in existing commercial or semi-commercial use environments, the increased cooling area of the evaporator and the improved space utilization of the evaporator significantly improve the cooling efficiency of the snow melter, thereby enabling the production and processing of snow melt products more quickly.

[0036] Example 1.

[0037] As a first embodiment of a snow melting machine that is easy to use according to the present invention, Figure 1-4 As shown. Specifically, the snow melter includes a housing 1 (in the drawings of this application, the housing 1 is only partially shown, and the shape of the housing is not limited to the shape shown in the drawings), a refrigeration component (not shown) located within the housing 1, and a power component 11. The main function of the housing 1 is to provide support for various functional modules or components, and different shapes are set according to the overall shape of the snow melter; the refrigeration component provides condensing agent for the snow melter to cool the food placed in the mixing drum; the power component 11 provides power for the snow melter. The drawings of this application only show a simple schematic diagram of the power component.

[0038] The snow melter also includes a processing module disposed on the upper portion of the housing 1, the processing module including a mixing drum 2, an evaporator 3, and a stirring paddle. The evaporator 3 and the stirring paddle are disposed within the mixing drum 2, forming a condensation chamber 22 within the mixing drum 2, wherein the evaporator 3 and the stirring paddle process the food in the condensation chamber 22. Preferably, the mixing drum 2 has an opening for placing food on the upper portion, and a drum cover 21 is disposed at the opening; the front end of the mixing drum 2 is also provided with a handle 23 and a discharge port 24, the discharge port 24 being connected to the condensation chamber 22. The handle 23 is operated to open the discharge port 24 to discharge the processed food in the mixing drum 2.

[0039] like Figure 2-4As shown, the evaporator 3 includes a cylinder, a spiral condensation channel, a condensation inlet 36 and a condensation outlet 37 connected to the spiral condensation channel, and a cylinder bracket 38. The cylinder includes an outer cylinder 31 and an inner cylinder 32, and the outer cylinder 31 and the inner cylinder 32 are arranged in a concentric ring shape, and the outer cylinder 31 and the inner cylinder 32 are closed and connected at the front end to form an internal space 35 inside the outer cylinder 31 and the inner cylinder 32. The evaporator 3 is provided with a spiral condensation pipe 33 located in the internal space 35, and the spiral condensation pipe 33 forms the spiral condensation channel. The spiral condensation pipe 33 is simultaneously fitted with the inner side wall of the outer cylinder 31 and the outer side wall of the inner cylinder 32, so that the surfaces of the outer cylinder 31 and the inner cylinder 32 located inside the mixing cylinder 2 simultaneously form cooling surfaces. Preferably, the outer cylinder 31 is longer in the axial direction than the inner cylinder 32. Since the outer cylinder 31 and the inner cylinder 32 are aligned at their front ends, the outer cylinder 31 forms a portion of the interior space 35 behind the rear end wall 34 of the inner cylinder 32. The condensation inlet 36 and the condensation outlet 37 are disposed within the interior space 35 formed at the rear of the outer cylinder 31. A cylinder bracket 38 is also provided at the rear end of the evaporator 3, through which the evaporator 3 is fixedly connected to the mixing drum 2. For example, the cylinder bracket 38 is provided with screw holes and is directly fixed to the side wall of the mixing drum 2 using screws.

[0040] The front end of the barrel is provided with an opening. An inner condensation chamber 6 is formed within the inner barrel 32 of the barrel, communicating with the condensation chamber 22. The opening forms a front communication port 61 connecting the inner condensation chamber 6 and the condensation chamber 22. Food placed within the mixing drum 2 can flow into the inner condensation chamber 6 through the front communication port 61, where it is cooled by the inner barrel 32. The food then flows back into the condensation chamber 22 through the front communication port 61, achieving cooling. By increasing the cooling area of the inner barrel 32 compared to the outer barrel 31, the snow melter achieves higher cooling efficiency and enables faster processing of the melted food. Furthermore, since food can flow into the barrel, the barrel no longer occupies excessive space within the mixing drum 2. Even if the barrel's length is increased to further increase the cooling area of the outer and inner barrels 31 and 32, the effective volume of the mixing drum 2 will not be affected. This makes the snow melter compact and lightweight, making it easy to operate and store.

[0041] In order to better realize the tumbling mixing of the ingredients in the mixing drum 2, the stirring paddle includes an outer stirring paddle 4 and an inner stirring paddle 5, the outer stirring paddle 4 is sleeved on the outside of the outer cylinder 31, the inner stirring paddle 5 is inserted into the inner cylinder 32, and is located in the inner condensation chamber 6. The front end of the inner stirring paddle 5 is provided with a driving section 53, the front end of the outer stirring paddle 4 is provided with a front stirring blade 41 and a transmission section 42, the outer stirring paddle 4 is connected to the driving section 53 by the transmission section 42, so that the outer stirring paddle 4 and the inner stirring paddle 5 rotate synchronously. Preferably, the inner stirring paddle 5 includes an inner stirring shaft 51, an inner stirring blade 52, and a transmission shaft 54, the inner stirring blade 52 is spiral and is located outside the inner stirring shaft 51, the transmission shaft 54 is extended backward by the rear end of the inner stirring shaft 51, and is connected to the power assembly 11 power, so that under the drive of the power assembly 11, the rotation of the inner stirring paddle 5 and the outer stirring paddle 4 is realized. The rear end wall 34 of the inner cylinder 32 has a through-hole 341 at its center for the transmission shaft 54 to pass through. A shaft seal 342 is located in the through-hole 341 and fits over the transmission shaft 54. Directly opening the through-hole at the rear end of the inner cylinder to accommodate the power assembly results in a simple structure and stable and reliable drive. Furthermore, the shaft seal prevents food from leaking out of the through-hole, ensuring safer and more reliable operation of the snow melter.

[0042] like Figure 2 、 3 As shown, the external stirring paddle 4 includes a front stirring blade 41, a transmission section 42, an external stirring blade 43, a bracket plate 44 and an end plate 45, wherein the front stirring blade 41 is arranged at the front end of the external stirring paddle 4, and when the external stirring paddle 4 is sleeved on the outside of the cylinder, it is located at the front of the cylinder, so that the ingredients located at the front of the cylinder can be mixed and stirred, making the mixing more uniform. The end plate 45 is located at the rear end of the external stirring paddle 4, and when the external stirring paddle 4 is sleeved on the outside of the cylinder, it is close to the rear end of the cylinder, and can mix and stir the ingredients located at the rear end of the cylinder. The outer stirring blade 43 is spiral and is connected to the end plate 45 and the front stirring blade 41 respectively. The support plate 44 is arranged to be an axially extending strip and extends from the rear end to the front end of the outer stirring paddle 4. The support plate 44 is also connected to the end plate 45 and the front stirring blade 41, and the support plate 44 is connected to the spirally arranged outer stirring blade 43 in the middle part. The support plate 44 can provide structural support for the outer stirring blade 43 to ensure the structural stability of the outer stirring blade 43.

[0043] Preferably, the outer stirring blade 43 is close to the outer wall of the outer cylinder 31, and the inner stirring blade 52 is close to the inner wall of the inner cylinder 32. In this way, when the inner stirring paddle 5 and the outer stirring paddle 4 are working, the food on the surface of the cylinder can be more thoroughly peeled off to avoid excessive cooling of the food when it remains on the surface of the cylinder for a long time.

[0044] When the snow melter of the present invention is in operation, a user places food into the mixing drum 2 through the upper opening of the mixing drum 2. The food then flows into the condensing chamber 22 and the inner condensing chamber 6. Upon activation, the outer and inner barrels of the mixing drum simultaneously form cooling surfaces, cooling the food within the condensing chamber 22 and the inner condensing chamber 6 simultaneously. This improves the cooling speed and efficiency of the snow melter. The outer and inner stirring paddles then tumble and mix the food, achieving uniform cooling. Because both the inner and outer surfaces of the evaporator can be cooled simultaneously, the evaporator's cooling efficiency is greatly improved, allowing the snow melter to completely cool food in a shorter time. Alternatively, the snow melter can be reduced in size without increasing cooling time. Specifically, because the evaporator is internally provided with an inner condensing chamber, food can enter and cool within the evaporator. Compared to existing technologies, the volume occupied by the evaporator itself is significantly reduced, significantly increasing the capacity of food that can be prepared in a single batch.

[0045] Because the evaporator can increase the cooling area without increasing its volume too much, even if the volume of the snow melter is reduced, the evaporator can still provide sufficient cooling area, ensuring that the food can fully exchange heat and that the snow melter can complete the cooling process without being affected by the external environment. Therefore, the present application is particularly suitable for lightweight and small-sized snow melters, thereby providing users with a snow melter product suitable for home use, which is convenient for users to operate and use, and also convenient for storage operations in a home environment. Of course, the present invention is also applicable to the existing commercial or semi-commercial use environment, and due to the improvement in refrigeration efficiency, it can also reduce the user's energy consumption.

[0046] As an optional solution, the evaporator cylinder body can form the spiral condensation channel by its own structure. For example, the outer wall of the inner cylinder is provided with a spiral groove, and the inner cylinder is fitted with the outer wall of the outer cylinder, thereby forming a spiral condensation channel between the spiral groove and the inner wall of the outer cylinder; or, the inner wall of the outer cylinder is provided with a spiral groove, and the spiral groove is fitted with the outer wall of the inner cylinder to close the upper opening of the spiral groove, thereby forming the spiral condensation channel between the spiral groove and the outer wall of the inner cylinder; or, the inner wall of the outer cylinder forms an inner spiral groove, and the outer wall of the inner cylinder forms an outer spiral groove. When the outer cylinder is sleeved on the outside of the inner cylinder, the inner and outer spiral grooves are arranged relative to each other and form a closed channel, and the spiral condensation channel is formed by the outer and inner spiral grooves.

[0047] As an optional solution, the stirring paddle can be set as an integrated structure. For example, the outer stirring paddle and the inner stirring paddle described in Example 1 are set as a fixed integrated part and plugged into the cylinder, while the outer stirring paddle is sleeved outside the outer cylinder and the inner stirring paddle is extended into the inner cylinder.

[0048] As an alternative, the outer paddle is mounted on the exterior of the drum, and the snow melter includes a power transmission structure that directly drives the outer paddle. The outer paddle rotates and simultaneously drives the inner paddle. This eliminates the need for a through hole at the rear end of the drum for transmission. For example, the inner sidewall of the mixing drum is provided with a drive gear connected to the power assembly, and the outer periphery of the rear end of the outer paddle is provided with transmission teeth. The drive gear meshes with the transmission teeth and drives the outer paddle. Reduced speed transmission can also be achieved by adjusting the number of teeth on the drive gear and transmission teeth.

[0049] As an optional solution, the outer and inner stirring paddles are each provided with a drive module, thereby enabling them to rotate synchronously, or to have different speeds, or to have different directions of rotation. Different transmission methods can be selected depending on how the stirring blades of the outer and inner stirring paddles are arranged.

[0050] As an optional solution, the spiral condensation channel can be configured as two layers. For example, the spiral condensation tube includes a double-layer tube arranged inside and outside, wherein the outer spiral condensation tube is in contact with the inner wall of the outer tube, and the inner spiral condensation tube is in contact with the outer wall of the inner tube, thereby further improving the cooling effect of the outer and inner tubes and further improving the operating efficiency of the snow melter.

[0051] As an optional solution, the evaporator may be located at the through hole without a shaft seal. For example, the evaporator may be directly provided with a bearing and a transmission structure at the through hole, the transmission structure and the cylinder being rotatably fixedly connected, the transmission structure being directly connected to the power assembly at one end of the internal space, and the transmission structure being detachably connected to the inner stirring paddle at one end of the internal condensing chamber.

[0052] Example 2.

[0053] As a convenient snow melting machine of the present invention, Figure 5 、 6 Specifically, the processing module is further disposed on a fixed bracket within the mixing drum, and the evaporator is mounted on the mixing drum via the fixed bracket. It should be noted that the separate descriptions of the first and second embodiments of the snow melter do not imply that the individual cases between the embodiments are completely independent of each other, but are merely intended to specifically illustrate several preferred technical solutions for the snow melter. Furthermore, the technical features and technical solutions of the various embodiments are universal and can be mutually referenced.

[0054] like Figure 5 、 6 As shown, the processing module includes a mixing drum 2, an evaporator 3, a stirring paddle and a fixing bracket 7, wherein the stirring paddle includes an outer stirring paddle 4 and an inner stirring paddle 5. The evaporator 3, the outer stirring paddle 4, the inner stirring paddle 5 and the fixing bracket 7 are all arranged in the mixing drum 2, and a condensation chamber 22 is formed inside the mixing drum 2.

[0055] The evaporator 3 includes a cylindrical body, a spiral condensation channel, a condensation inlet 36, and a condensation outlet 37 connected to the spiral condensation channel. The cylindrical body includes an outer cylinder 31 and an inner cylinder 32. The outer cylinder 31 and the inner cylinder 32 are arranged in a concentric, cylindrical ring shape. The outer cylinder 31 is sleeved outside the inner cylinder 32, and the front and rear ends of the outer cylinder 31 and the inner cylinder 32 are sealed and connected, forming an internal space within the outer cylinder 31 and the inner cylinder 32. The evaporator 3 is provided with a spiral condensation tube 33 within the internal space. The spiral condensation tube 33 forms the spiral condensation channel. The spiral condensation tube 33 is sandwiched between the outer cylinder 31 and the inner cylinder 32 and is in contact with the outer cylinder 31 and the inner cylinder 32, so that the outer surfaces of the outer cylinder 31 and the inner cylinder 32 form cooling surfaces. When food comes into contact with the surface of the outer cylinder 31 or the inner cylinder 32 located on the mixing drum, it can exchange heat with the condensing agent in the spiral condensation tube 33, thereby achieving a cooling process. Thus, an inner condensation chamber 6 communicating with the condensation chamber 22 is formed inside the inner cylinder 32 , and the food in the inner condensation chamber 6 and the food in the condensation chamber 22 are circulated, mixed and stirred with each other.

[0056] The front and rear ends of the outer cylinder 31 and the inner cylinder 32 are both sealed and connected, so that the cylinder body is formed with a communication port at the front and rear ends that connects the inner condensation chamber 6 and the condensation chamber 22. The front end of the cylinder body is formed with a front communication port 61, and the rear end of the cylinder body is formed with a rear communication port 62. The condensation inlet 36 and the condensation outlet 37 pass through the cylinder body to communicate with the spiral condensation tube 33. Preferably, the condensation inlet 36 and the condensation outlet 37 are located at the connection of the rear ends of the outer cylinder 31 and the inner cylinder 32, and pass through the connecting wall of the outer cylinder 31 and the inner cylinder 32.

[0057] The evaporator 3 is fixed to the side wall of the mixing drum 2 via the fixing bracket 7. The fixing bracket 7 includes a fixing seat 71, a bracket connecting rod 72, and a fixing ring 73. The fixing seat 71 is fixedly connected to the side wall of the mixing drum 2. Preferably, the fixing seat 71 is directly fixed to the side wall of the mixing drum 2 via screws. The bracket connecting rod 72 connects the fixing seat 71 and the fixing ring 73. Preferably, the bracket connecting rod 72 is a plurality of cylindrical rods extending along the axial direction. The plurality of bracket connecting rods 72 are arranged circumferentially, and a stirring channel 75 is formed between adjacent bracket connecting rods 72. The front end surface of the fixing ring 73 is provided with a fixing groove 74, and the evaporator 3 is installed in the fixing groove 74. Preferably, the fixing groove 74 is also provided with a seal 76 for elastically limiting the evaporator 3. The seal 76 ensures the reliable installation of the evaporator 3 and prevents the evaporator 3 and the fixing ring 73 from hard contact and collision, thereby generating friction and noise. A channel communicating with the rear communication port 62 is provided at the center of the fixing ring 73 , so that the food discharged from the inner condensation chamber 6 flows through the fixing ring 73 and then flows back into the condensation chamber 22 through the stirring channel 75 between the support connecting rods 72 .

[0058] The outer cylinder 21 is provided with an outer stirring paddle 4, and the inner cylinder 22 is provided with an inner stirring paddle 5. The inner stirring paddle 5 and the outer stirring paddle 4 are connected to each other by power, so that the outer stirring paddle 4 and the inner stirring paddle 5 can rotate synchronously.

[0059] When the snow melter of this embodiment is in operation, the user pours the food into the mixing drum 2 through the opening above the mixing drum 2. At this time, the food flows into the condensation chamber 22 and the inner condensation chamber 6. After starting the snow melter, the outer and inner cylinders of the cylinder simultaneously form cooling surfaces. The food in the condensation chamber 22 and the inner condensation chamber 6 are cooled and processed at the same time. The outer and inner stirring paddles are then used to roll and mix the food, thereby achieving uniform cooling of the food. The front and rear ends of the cylinder both have openings. The spiral inner stirring blades of the inner stirring paddle can push the food into the inner condensation chamber from the front connecting port. After being cooled and processed in the inner condensation chamber, the food flows out of the inner condensation chamber from the rear connecting port, passes through the stirring channel, and then flows back into the condensation chamber. The food is more fully mixed and stirred with the food in the condensation chamber, thereby making the cooling process of the snow melter more uniform.

[0060] As an optional solution, the rear end of the evaporator has a bracket, and the bracket is connected to the inner circumference of the cylinder so that the bracket supports the cylinder to prevent the cylinder from being squeezed and deformed.

[0061] As an optional solution, the rear end of the evaporator is provided with a rear end wall, and the rear end wall is provided with a through hole for food to pass through. At the same time, the transmission shaft of the inner stirring paddle passes through the through hole of the rear end wall and is connected to the power component.

[0062] As an optional solution, since the front and rear ends of the cylinder are both provided with openings, an internal stirring paddle may not be provided, and only an external stirring paddle may be provided. The external stirring paddle pushes the food to flow in from the front connecting port, and after passing through the internal condensation chamber, it is discharged from the rear connecting port.

[0063] Example 3.

[0064] As a third embodiment of the easy-to-use snow melting machine of the present invention, Figure 7 As shown, compared to Example 2, the evaporator in this embodiment further includes a condensation inlet pipe, which extends into the interior space of the cylinder and communicates with the spiral condensation channel at the front end of the cylinder. It should be noted that the separate descriptions of Example 1, Example 2, and Example 3 of the snow melter do not imply that the individual cases among the several embodiments are completely independent of each other, but are merely intended to specifically illustrate several preferred technical solutions of the snow melter. The technical features and technical solutions of the several embodiments are universal and can be mutually referenced.

[0065] like Figure 7As shown, the evaporator 3 includes a cylindrical body, a spiral condensation channel, a condensation inlet 36 and a condensation outlet 37 connected to the spiral condensation channel. The cylindrical body includes an outer cylinder 31 and an inner cylinder 32. The outer cylinder 31 and the inner cylinder 32 are arranged in a concentric and cylindrical ring shape. The outer cylinder 31 is sleeved on the outside of the inner cylinder 32, and the front ends of the outer cylinder 31 and the inner cylinder 32 are sealed and connected, forming an internal space 35 inside the outer cylinder 31 and the inner cylinder 32. The evaporator 3 is provided with a spiral condensation pipe 33 located in the internal space 35, and the spiral condensation pipe 33 forms the spiral condensation channel. The spiral condensation pipe 33 is in contact with both the outer cylinder 31 and the inner cylinder 32.

[0066] Preferably, the evaporator 3 further includes a condensation inlet pipe 39, which extends into the internal space 35 and is clamped between the outer cylinder 31 and the inner cylinder 32 to extend to the closed front end of the outer cylinder 31 and the inner cylinder 32. The condensation inlet 36 is connected to the spiral condensation tube 33 through the condensation inlet pipe 39. As a result, the refrigerant of the refrigeration component of the snow melter can be directly transferred to the front end of the spiral condensation tube 33 through the condensation inlet pipe 39. In this way, the refrigerant can flow directly to the front end of the cylinder, exchange heat with the food at the front end, and gradually flow to the rear end, and continue to exchange heat with the food during the flow process. In this way, the cooling efficiency of the evaporator is further improved.

[0067] Preferably, the spiral condenser tube 4 can be flattened or grooved at the intersection between the outer and inner cylinders 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 and the inner wall of the inner cylinder, which come into contact with the food to condense, maintain smooth rotating surfaces, thus ensuring stable operation of the outer and inner stirring paddles and preventing food residue from remaining in blind spots.

[0068] It can be understood that the side wall of the outer cylinder or the inner cylinder is provided with a groove, and the condensation inlet pipe is arranged in the groove of the outer cylinder or the inner cylinder and extends from the rear end to the front end of the cylinder.

[0069] In the description of this application, it should be understood that the directions or positional relationships 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 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.

[0070] 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.

[0071] 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.
