Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice-making technology, and in particular to a cold drink device. Background Technology
[0002] A shaved ice machine is a type of cold drink machine that uses an internal refrigeration system and a snow-making system to prepare snowflake-like shaved ice. The evaporator in the snow-making system is connected to the refrigerant pipeline in the refrigeration system via a return gas pipe, so that the refrigerant is delivered into the evaporator and the refrigerant after heat exchange is sent out of the evaporator, completing the refrigerant cycle in the evaporator.
[0003] The evaporator exchanges heat with the liquid feed by rotating, thus preparing the slush. However, when the evaporator is rotating to make ice, the return gas pipe inside the evaporator is easily affected by the rotation, causing the return gas pipe to rotate as well, which affects the ice-making performance of the system. Utility Model Content

[0010] As an improvement to the above solution, a fixed protrusion is formed on the side of the body facing the receiving cavity, and the fixed protrusion forms a slot. The slot is inclined along a preset direction, which is towards the rotation center of the evaporator assembly; the first end of the return gas pipe is installed in the slot.

[0024] 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.
[0025] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cold drink equipment includes a body 1. The body 1 has an ice-making chamber 11 and a receiving chamber 12 that are separated from each other. The ice-making chamber 11 is equipped with an evaporator assembly 2, and the receiving chamber 12 is equipped with a drive assembly 3 that is drivenly connected to the evaporator assembly 2. The evaporator assembly 2 is equipped with a return air pipe 4. The first end of the return air pipe 4 faces the receiving chamber 12, and the first end of the return air pipe 4 is connected to the body 1. The return air pipe 4 and the body 1 are kept relatively fixed.
[0026] In this embodiment of the cold drink equipment, the drive assembly 3 can drive the evaporator assembly 2 to rotate, so that the evaporator assembly 2 can exchange heat with the liquid in the ice-making chamber 11 to complete the preparation of shaved ice. Since the first end of the return gas pipe 4 is connected to the body 1 after facing the receiving chamber 12, and the return gas pipe 4 and the body 1 are kept relatively fixed, it is ensured that when the evaporator assembly 2 rotates relative to the body 1, the return gas pipe 4 will not rotate due to the rotation of the evaporator assembly 2, effectively ensuring the overall performance of the internal system of the cold drink equipment.
[0027] Specifically, the return gas pipe 4 is connected to at least one of the body 1 through a connecting part. The return gas pipe 4 and the body 1 are connected through the connecting part, and the extending direction of the connecting part is toward the rotation center of the evaporator assembly 2. The connection part and the body 1 are used to limit and fix the return gas pipe 4, counteract the torque and other forces on the return gas pipe 4 when the evaporator assembly 2 rotates, ensure the connection stability between the return gas pipe 4 and the body 1, and further ensure that the return gas pipe 4 will not rotate due to the rotation of the evaporator assembly 2.
[0028] As a first optional embodiment, such as Figures 2 to 4As shown, the first end of the return gas pipe 4 is connected to a connecting pipe 41. The connecting pipe 41 can be used to connect the return gas pipe 4 and the refrigerant pipeline of the refrigeration system to provide refrigerant to the evaporator assembly 2 and to transport the refrigerant gas in the evaporator assembly 2 back to the refrigeration system. The connecting pipe 41 is connected to the body 1, and the connecting pipe 41 is arranged at an angle relative to the return gas pipe 4. That is, in this embodiment, the connecting part is the connecting pipe 41 at the first end of the return gas pipe 4. The connecting pipe 41, which is arranged at an angle relative to the return gas pipe 4, is connected and fixed to the body 1 so that the reverse torque of the connecting pipe 41 on the return gas pipe 4 can be used to constrain the radial rotation of the return gas pipe 4, thereby ensuring that the return gas pipe 4 is fixedly installed in the body 1 and will not have a rotation tendency.
[0029] It should be noted that, in order to fix the connecting pipe 41 to the body 1 and ensure the constraint effect of the connecting pipe 41 on the return air pipe 4, the connecting pipe 41 can be connected to the side of the body 1 by means of clamp connection, flange connection, or welding, so as to ensure the connection stability between the connecting pipe 41 and the body 1.
[0030] As a second optional embodiment, such as Figures 2 to 4 As shown, a fixed protrusion 13 is formed on the side of the body 1 facing the receiving cavity 12. The fixed protrusion 13 forms a slot 131. The slot 131 is inclined along a preset direction, which is towards the rotation center of the evaporator assembly 2. The first end of the return pipe 4 is installed in the slot 131. That is, in this embodiment, the connecting part is the slot 131 inclined on the side of the body 1. The return pipe 4 is connected through the inclined slot 131. The slot 131 can be used to apply a constraint force to the return pipe 4 in the opposite direction to the rotation of the evaporator assembly 2, thereby restricting the radial rotation of the return pipe 4 and preventing the return pipe 4 from rotating due to the linkage of the evaporator assembly 2.
[0031] It should be noted that the fixed protrusion 13 is integrally formed with the body 1.
[0032] As a third optional embodiment, such as Figures 2 to 4 As shown, the receiving cavity 12 is provided with a limiting member 14, which is connected to the body 1 and covers the first end of the return gas pipe 4. That is, in this embodiment, the connecting part is the limiting member 14 of the receiving cavity 12. The limiting member 14 covers and wraps the first end of the return gas pipe 4, and the radial rotation of the return gas pipe 4 is restricted by the side wall of the limiting member 14 in contact with the return gas pipe 4, thereby preventing the return gas pipe 4 from rotating along with the evaporator assembly 2.
[0033] Specifically, such as Figure 3As shown, the limiting member 14 has a limiting hole 141 formed on the side facing the evaporator assembly 2. The limiting member 14 is connected to the first end of the return pipe 4 through the limiting hole 141, and the inner wall surface of the limiting hole 141 is interference-fitted with the outer wall surface of the return pipe 4. Thus, the radial pressure applied by the limiting member 14 to the return pipe 4 enhances the friction between the limiting hole 141 and the return pipe 4, ensuring that the return pipe 4 can remain relatively fixed with the limiting member 14. Furthermore, the cooperation between the body 1 and the limiting member 14 further enhances the anti-rotation effect of the limiting member 14 on the return pipe 4.
[0034] It should be noted that the limiting component 14 can be connected to the side of the machine body 1 by means of threaded connection, flange connection, clamp connection, etc., as long as the connection stability between the limiting component 14 and the machine body 1 can be guaranteed, which will not be elaborated here.
[0035] As the most preferred embodiment of this utility model, a connection structure combining the above three embodiments can be used to restrict the rotation of the return air pipe 4. Specifically, the first end of the return air pipe 4 extends out of the receiving cavity 12, and the end of the first end of the return air pipe 4 is connected to a limiting member 14, which covers the first end of the return air pipe 4 through a limiting hole 141. An inclined connecting hole is also formed inside the limiting member 14, and one end of the connecting pipe 41 passes through the connecting hole to the first end of the return air pipe 4; a fixing protrusion 13 is formed on the side of the body 1, and the other end of the connecting pipe 41 is embedded in the slot 131 of the fixing protrusion 13. At the same time, the bottom of the limiting member 14 is inclined to abut against the fixing protrusion 13, thereby using the cooperation of the connecting pipe 41, the fixing protrusion 13 and the limiting member 14 to ensure that the return air pipe 4 will not rotate with the evaporator assembly 2.
[0036] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the drive assembly 3 includes a drive component 31 and a transmission component 32. The transmission component 32 is connected to the drive component 31. The drive component 31 is installed on the body 1. The transmission component 32 is rotatably connected to the evaporator assembly 2. The drive component 31 drives the transmission component 32 to rotate, which in turn drives the evaporator assembly 2 to rotate. After the outer wall of the evaporator assembly 2 exchanges heat with the liquid, a uniformly distributed ice layer can be formed on the outer wall of the evaporator assembly 2, which facilitates the subsequent preparation of ice slush.
[0037] Preferably, the driving component 31 is a stepper motor, and the housing of the stepper motor is detachably connected to the side of the machine body 1 facing the receiving cavity 12 by fasteners such as bolts or studs.
[0038] Specifically, the transmission component 32 includes a driving wheel and a driven wheel that are connected by transmission. The driving wheel is rotatably connected to the output shaft of the drive component 31, and the driven wheel is rotatably connected to the rotating shaft of the evaporator assembly 2, so that the drive component 31 drives the driving wheel and the driven wheel to rotate synchronously, thereby driving the evaporator assembly 2 to rotate, and ensuring the uniformity of the thickness of the ice layer formed on the outer wall of the evaporator assembly 2.
[0039] As an optional embodiment, both the driving wheel and the driven wheel are pulleys, and they are connected by a conveyor belt. Of course, in other embodiments, both the driving wheel and the driven wheel can be gears, meshed together, or other transmission groups, which can be selected according to the actual situation.
[0040] It should also be noted that, such as Figure 1 and Figure 2 As shown, a reducer 33 is provided between the drive component 31 and the drive wheel. The reducer 33 can adjust the torque output by the drive component 31, thereby controlling the rotation speed of the evaporator assembly 2. This allows for adjustment of the contact time between the evaporator assembly 2 and the liquid, further controlling the thickness and texture of the ice layer on the outer wall of the evaporator assembly 2, increasing the quality of the finished slush produced by the cold drink equipment, and meeting the needs of different users.
[0041] The reducer 33 can be a worm gear reducer 33 or a multi-stage gear reducer 33, so as to adjust the reduction ratio of the reducer 33 and thus control the ice thickness.
[0042] Among them, such as Figure 5 As shown, a first bearing 21 is installed between the rotating shaft of the evaporator assembly 2 and the return gas pipe 4, and a second bearing 22 is installed between the rotating shaft of the evaporator assembly 2 and the body 1. The cooperation of the first bearing 21 and the second bearing 22 allows the evaporator assembly 2 to rotate relative to the body 1 and the return gas pipe 4, ensuring the rotational stability of the evaporator assembly 2. Simultaneously, the inner ring, outer ring, and intermediate rolling element of the first bearing 21 separate the rotating shaft of the evaporator assembly 2 from the return gas pipe 4, further reducing the impact of the rotation of the evaporator assembly 2 on the return gas pipe 4, thereby further preventing the return gas pipe 4 from exhibiting a rotational tendency.
[0043] Among them, such as Figure 5 As shown, a seal 23 is provided between the return pipe 4 and the rotating shaft of the evaporator assembly 2 to seal the connection gap between the return pipe 4 and the rotating shaft of the evaporator assembly 2, so as to prevent the refrigerant inside the evaporator assembly 2 from leaking and to ensure the safety performance of the refrigeration equipment.
[0044] The above description is the preferred embodiment 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 invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
