Description

Technical Field

[0001] This utility model relates to the field of slush machine technology, and in particular to an evaporation device for a slush machine and a slush machine. Background Technology

[0002] In the current refrigerated beverage industry (such as milk tea shops and fast food chains), slush machines are widely used because they can quickly prepare slushies. Most existing slush machines perform cooling inside the discharge cylinder, with the evaporator typically located inside. This evaporator structure is mostly coil-type, where refrigerant pipes are coiled inside the discharge cylinder. The refrigerant absorbs heat through the flow of heat within the pipes, thus cooling the slush. However, this method of cooling inside the discharge cylinder has several drawbacks. Firstly, the evaporator occupies a significant amount of space within the discharge cylinder, severely compressing its effective storage space. To meet certain production demands, businesses must increase the overall size of the slush machine, resulting in excessive space usage. Secondly, because the evaporator is located inside the discharge cylinder, the heat transfer distance between the refrigerant and the slush is relatively long. During heat transfer, the refrigerant must first cool the coil metal body before conducting heat through the cylinder wall (heat transfer chain: refrigerant - coil - sleeve - discharge cylinder), resulting in a long heat transfer path and high thermal resistance. Therefore, the existing evaporation devices of snow slush machines have disadvantages such as large size, low space utilization, long heat transfer path, and low heat transfer efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an evaporation device for a slush machine, which can perform refrigeration and heat exchange outside the discharge cylinder, save space inside the discharge cylinder, improve space utilization, and has a short heat transfer path and high heat transfer efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides an evaporation device for a slush machine, which is sleeved outside the discharge cylinder of the slush machine and includes a sleeve and a pipe wall, wherein the pipe wall surrounds the wall surface of the sleeve.

[0005] The discharge cylinder is located inside the sleeve and abuts against the inner wall of the sleeve. The pipe wall is located outside the sleeve and abuts against the outer wall of the sleeve. The inner cavity of the pipe wall and the sleeve form a refrigeration channel, through which the refrigerant can flow.

[0006] The tube wall includes multiple spiral grooves, and the ratio of the maximum distance from the inner wall of the spiral groove to the sleeve to the distance between two adjacent spiral grooves is between 2:13 and 10:13.

[0007] As an improvement to the above solution, the pipe wall extends in a spiral shape, the inner wall of the spiral groove is a concave groove, and the opening of the spiral groove faces the sleeve.

[0008] As an improvement to the above solution, the inner wall of the spiral tube groove is a concave arc groove, and the arc groove of the spiral tube groove and the sleeve form the refrigeration channel.

[0009] As an improvement to the above solution, a connecting band is provided between adjacent spiral tube grooves. The connecting band protrudes in the direction of the sleeve. The connecting band includes an abutting part and connecting parts connected to both sides of the abutting part. The connecting parts are respectively connected to two adjacent spiral tube grooves, and the abutting part abuts against the sleeve.

[0010] As an improvement to the above solution, the ratio of the width of the connecting strip to the distance between two adjacent spiral tube grooves is in the range of 1:13 to 5:13.

[0011] As an improvement to the above solution, the evaporation device for the slush machine further includes a housing, which is located on the side of the pipe wall away from the sleeve. The housing can surround the pipe wall and the sleeve, and a foaming cavity is formed between the housing and the sleeve.

[0012] As an improvement to the above solution, the evaporation device for the slush machine further includes a first temperature sensing head and / or a second temperature sensing head. The first temperature sensing head is located at the bottom of the discharge cylinder near the discharge port, and the second temperature sensing head is located at the bottom of the discharge cylinder near the inlet. The bottom of the outer shell is provided with a foaming hole, and the first temperature sensing head and / or the second temperature sensing head passes through the foaming cavity and can extend into the discharge cylinder.

[0013] As an improvement to the above solution, one end of the outer shell is provided with a first end plate, the first end plate is provided with a first limiting boss, the first limiting boss extends toward the inside of the outer shell, the first limiting boss can be inserted into the sleeve, and the outer side wall of the first limiting boss can abut against the inner side wall of the sleeve.

[0014] As an improvement to the above solution, a second end plate is provided at the end of the outer casing away from the first end plate. The second end plate is provided with a second limiting boss and an outer limiting plate. The second limiting boss extends toward the inner side of the outer casing, and the outer limiting plate extends toward the axial direction of the sleeve and is connected to the second limiting boss. The outer side of the second limiting boss can abut against the outer side wall of the sleeve, and the outer limiting plate can abut against the end of the sleeve.

[0015] This utility model also provides a slush machine, including the evaporation device for the slush machine as described above.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This invention relates to an evaporation device for a slush machine, comprising a sleeve and a tube wall. The tube wall surrounds the wall of the sleeve, and the discharge cylinder is located inside the sleeve. Raw materials can exchange heat within the discharge cylinder to form slush. Traditional slush machines place the evaporation tube inside the discharge cylinder, with the refrigerant flowing within it. The heat exchange path is "refrigerant-coil-sleeve-discharge cylinder". Unlike traditional slush machines, this invention places the discharge cylinder inside the sleeve and abuts against the inner wall of the sleeve. The tube wall is located outside the sleeve and abuts against the outer wall of the sleeve. Thus, the discharge cylinder is located inside the sleeve, and the refrigeration channel formed by the inner cavity of the tube wall and the sleeve is located outside the discharge cylinder. This utilizes the space inside the discharge cylinder to store raw materials and slush, improving space utilization. Furthermore, in terms of heat transfer, the heat exchange path of this invention is "refrigerant-sleeve-discharge cylinder", which is shorter than the traditional heat exchange path, resulting in higher heat exchange efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] See Figure 1 and Figure 2This utility model discloses an evaporation device for a slush machine, which is fitted around the discharge cylinder 8 of the slush machine. It includes a sleeve 1 and a pipe wall 2. The sleeve 1 is used to fix the pipe wall 2 and forms a flow space for the refrigerant, enabling heat transfer. The pipe wall 2 surrounds the wall of the sleeve 1 and is made of a spiral tube with an open side. The discharge cylinder 8 is located inside the sleeve 1 and abuts against the inner wall of the sleeve 1. Therefore, the discharge cylinder 8 is located inside the sleeve 1 and can hold raw materials. The raw materials are cooled and slush-formed within the discharge cylinder 8, making full use of the space inside the discharge cylinder 8. The discharge cylinder 8 abuts against the sleeve 1 to ensure heat transfer efficiency. The tube wall 2 is located outside the sleeve 1 and abuts against the outer wall of the sleeve 1, thus the tube wall 2 and the discharge cylinder 8 are separated by the sleeve 1. Since the tube wall 2 is made of a spiral tube with an unclosed side, it has an internal cavity. The inner cavity of the tube wall 2 and the sleeve 1 form a refrigeration channel 3, and the outer wall of the sleeve 1 forms a structure that encloses the tube wall 2. Therefore, the refrigeration channel 3 is enclosed, allowing the refrigerant to flow within it. During heat transfer, the refrigerant flows within the refrigeration channel 3. Since it does not need to pass through the tube wall 2, the cold energy first passes through the sleeve 1 and then enters the discharge cylinder 8, forming a heat exchange path of "refrigerant-sleeve-discharge cylinder". In contrast, the heat exchange path of a traditional slush machine is "refrigerant-coil-sleeve-discharge cylinder". Compared to the traditional slush machine heat exchange path, the heat exchange path of the evaporation device of this utility model for a slush machine is shorter and the heat exchange efficiency is higher.

[0024] The beneficial effects of this utility model embodiment are as follows:

[0025] The evaporation device for the slush machine in this embodiment of the utility model is provided with a sleeve 1 and a pipe wall 2. The pipe wall 2 surrounds the wall surface of the sleeve 1, and the discharge cylinder 8 is provided inside the sleeve 1. The raw material can exchange heat in the discharge cylinder 8 to form slush. Traditional slush machines place the evaporator tube inside the discharge cylinder 8, with the refrigerant flowing within the evaporator tube. The heat exchange path is "refrigerant-sleeve-discharge cylinder". Unlike traditional slush machines, this invention places the discharge cylinder 8 inside the sleeve 1 and abuts against the inner wall of the sleeve 1. The pipe wall 2 is located outside the sleeve 1 and abuts against the outer wall of the sleeve 1. Thus, the discharge cylinder 8 is located inside the sleeve 1, and the refrigeration channel 3 formed by the inner cavity of the pipe wall 2 and the sleeve 1 is located outside the discharge cylinder 8. This makes full use of the space inside the discharge cylinder 8, which can be used to store raw materials and slush, improving space utilization. In terms of heat transfer, the heat exchange path of this invention is "refrigerant-coil-sleeve-discharge cylinder", which is shorter than the traditional heat exchange path, resulting in higher heat exchange efficiency.

[0026] Specifically, the pipe wall 2 extends in a spiral shape, and the pipe wall 2 is coiled into a spiral shape. The inner side of the spiral structure is an unclosed part, which forms a spiral groove 21. The pipe wall 2 includes multiple spiral grooves 21. The inner wall of the spiral groove 21 is a concave groove. The groove opening of the spiral groove 21 faces the sleeve 1, so that it can form a closed refrigeration channel 3 with the sleeve 1.

[0027] See Figure 3 In this embodiment of the invention, the inner wall of the spiral tube groove 21 is a concave arc groove, which optimizes the refrigerant flow and reduces flow resistance. The arc groove of the spiral tube groove 21 and the sleeve 1 form the refrigeration channel 3. A connecting band 4 is provided between adjacent spiral tube grooves 21 to connect them. The connecting band 4 protrudes towards the sleeve 1 and includes an abutment portion 41 and connecting portions 42 connected to both sides of the abutment portion 41. The connecting portions 42 are respectively connected to two adjacent spiral tube grooves 21. The abutment portion 41 abuts against the sleeve 1, which can fix the spiral tube groove 21 to the outer wall of the sleeve 1.

[0028] To achieve better refrigeration and structural performance, the ratio of the maximum distance from the inner wall of the spiral tube groove 21 to the sleeve 1 to the distance between two adjacent spiral tube grooves 21 is between 2:13 and 10:13. When the ratio is less than 2:13, the spiral tube is relatively flat and can accommodate less refrigerant, easily creating a throttling effect, which is not conducive to refrigeration and heat exchange. Conversely, when the ratio is greater than 10:13, the cross-section of the spiral tube groove 21 is too large, which is not conducive to refrigerant flow and wastes space. The ratio of the width of the connecting strip 4 to the distance between two adjacent spiral grooves 21 is between 1:13 and 5:13. When the ratio is less than 1:13, the width of the abutment portion 41 is too small, making it difficult to provide a fixed connection. Conversely, when the ratio is greater than 5:13, the spacing between adjacent spiral grooves 21 is too large, reducing the number of spiral grooves 21 and the effective heat exchange area, thus lowering the heat exchange efficiency. In actual production, a reasonable selection within the above ratio range can be made based on the specific specifications of the slush machine and its refrigeration requirements.

[0029] The evaporation device for the slush machine also includes a housing 5, which is located on the side of the pipe wall 2 away from the sleeve 1. The housing 5 can surround the pipe wall 2 and the sleeve 1 and seal the pipe wall 2 and the sleeve 1. A foaming cavity 51 is formed between the housing 5 and the sleeve 1, and a foaming insulation layer is provided in the foaming cavity 51.

[0030] See Figure 2 The evaporation device for the slush machine further includes a first temperature sensor 6 and / or a second temperature sensor 7. In some embodiments, the sensing component includes only the first temperature sensor 6; in other embodiments, the sensing component may include both the first temperature sensor 6 and the second temperature sensor 7. The first temperature sensor 6 is located at the bottom of the discharge cylinder 8 near the discharge port and can detect the temperature of the slush near the discharge port. Using this temperature as the control temperature for freezing allows for a closer approximation of the temperature at discharge, thus providing more precise control. The second temperature sensor 7 is located at the bottom of the discharge cylinder 8 near the inlet. Working in conjunction with the first temperature sensor 6, the temperature difference between the first and second temperature sensors 7 allows for the acquisition of the average temperature within the discharge cylinder 8. Using this average temperature for control ensures that most of the liquid or the desired freezing effect is achieved.

[0031] See Figure 2 The bottom of the outer shell 5 is provided with foaming openings 52. During production, foaming material is poured into the foaming openings 52, and after foaming, the foamed insulation layer is formed, which can insulate the sleeve 1 and the discharge cylinder 8. The first temperature sensor 6 and / or the second temperature sensor 7 pass through the foaming cavity 51 and can extend into the discharge cylinder 8. In traditional slush machines, the foaming layer is usually located inside the sleeve 1 rather than on the outside. The foaming layer cannot insulate the discharge cylinder 8 outside the sleeve 1, so the insulation performance is poor. However, in this embodiment of the invention, the foamed insulation layer can simultaneously insulate the sleeve 1 and the discharge cylinder 8, which not only ensures the heat exchange effect, but also ensures that the slush receives sufficient insulation during the freezing process, thereby improving energy efficiency and reducing power consumption.

[0032] See Figure 3 To fix the sleeve 1, one end of the outer shell 5 is provided with a first end plate 53. The first end plate 53 is provided with a first limiting boss 531. The first limiting boss 531 extends toward the inner side of the outer shell 5. When installing the sleeve 1, the sleeve 1 is directly inserted into the outer shell 5. The end of the sleeve 1 abuts against the inner side of the outer shell 5 to form an axial limit, while the first limiting boss 531 can be inserted into the sleeve 1. The outer side wall of the first limiting boss 531 can abut against the inner side wall of the sleeve 1 to form a radial limit.

[0033] See Figure 4 At the other end, a second end plate 54 is provided at the end of the outer casing 5 away from the first end plate 53. The second end plate 54 is provided with a second limiting boss 541 and an outer limiting plate 542. The second limiting boss 541 extends toward the inner side of the outer casing 5, and the outer limiting plate 542 extends toward the axial direction of the sleeve 1 and is connected to the second limiting boss 541. After the sleeve 1 is inserted, the outer side of the second limiting boss 541 can abut against the outer side wall of the sleeve 1 to form a radial limit, and the outer limiting plate 542 can abut against the end of the sleeve 1 to form an axial limit.

[0034] This utility model also discloses a slush machine (not shown in the attached drawings), including the evaporation device for the slush machine as described above. The pipe wall 2 of the evaporation device for the slush machine surrounds the wall of the sleeve 1. Unlike traditional slush machines, this utility model's slush machine places the discharge cylinder 8 inside the sleeve 1 and abuts against the inner wall of the sleeve 1, while the pipe wall 2 is located outside the sleeve 1 and abuts against the outer wall of the sleeve 1. Thus, the discharge cylinder 8 is located inside the sleeve 1, and the refrigeration channel 3 formed by the inner cavity of the pipe wall 2 and the sleeve 1 is located outside the discharge cylinder 8. Therefore, the space inside the discharge cylinder 8 is utilized for storing raw materials and slush, improving space utilization. In terms of heat transfer, the heat exchange path of this utility model is "refrigerant-coil-sleeve-discharge cylinder," which is shorter than the traditional heat exchange path, resulting in higher heat exchange efficiency.

[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
