Description

TECHNICAL FIELD

[0001] The utility model relates to the field of refrigeration household electrical appliances, in particular to a progressive slush preparation system of slush machine. BACKGROUND

[0002] The slush machine is also called snow melting machine, which is a cold drink equipment for freezing liquid drinks such as coke, wine, coffee, soda, juice, chocolate and milk into cool and refreshing snow melting beverages. The refrigeration assembly of the slush machine includes a compressor, a condenser and an evaporator, etc. The evaporator of the slush machine on the market is immersed in the beverage solution, and the beverage solution in the solution cylinder exchanges heat with the beverage solution in the solution cylinder through the outer wall of the evaporator to form ice crystals. However, the disadvantages of this refrigeration method are also very obvious:

[0003] Large loss of cold quantity transfer: during the refrigeration process, the beverage solution in the solution cylinder continuously absorbs heat from the external environment through the outer wall of the solution cylinder, which will greatly neutralize the cold quantity transferred by the evaporator, resulting in loss of cold quantity, thereby directly affecting the refrigeration efficiency of the slush machine;

[0004] Low refrigeration efficiency: the core of heat exchange in the evaporator is the tightly wound refrigerant pipe winding. The current refrigerant pipe winding process cannot solve the fundamental problem that the outer side of the refrigerant pipe winding cannot perfectly match the inner wall of the evaporator shell. The contact area is too small, which reduces the heat exchange area, thereby directly affecting the conduction effect of the cold quantity, and the refrigeration efficiency of the beverage solution is greatly reduced;

[0005] Time-consuming and power-consuming: the traditional working method of the slush machine is to freeze all the beverage solution in the solution cylinder together. The large amount of beverage solution frozen at one time results in a long time consumption. In addition, the 360-degree large-area heat absorption of the outer wall of the solution cylinder directly affects the refrigeration efficiency and the energy consumption. The traditional slush machine needs to be turned on for more than one hour to make slush cold drinks. Moreover, the beverage solution cannot be supplemented during the slush making process. Therefore, the existing slush machine is not only time-consuming and power-consuming, but also not flexible enough for use, which cannot meet the sudden cold drink demand and the user experience is poor.

[0006] With the improvement of living standards, more and more consumers hope to enjoy the fun of quickly making slush cold drinks at home. However, the traditional slush machine for making slush cold drinks is time-consuming and power-consuming. Therefore, how to design a slush machine refrigeration system with high-efficiency refrigeration, low energy consumption and the ability to supplement raw materials during use has become a technical problem to be solved. UTILITY MODEL CONTENTS

[0007] The utility model aims at overcoming the deficiencies of the prior art, and provides a progressive slush preparation system of slush machine, which has the characteristics of high-efficiency refrigeration, low energy consumption, reliable performance and the ability to supplement raw materials during use.

[0008] The purpose of this utility model is achieved as follows:

[0009] A progressive slush preparation system for a slush machine includes an evaporator for refrigeration, which is disposed within a storage cylinder. The evaporator includes a refrigerant pipe winding for introducing refrigerant. The progressive slush preparation system also includes a refrigeration chamber providing the necessary space for ice crystal production and a storage cylinder for freezing and storing ice crystals. A hopper for storing and supplying beverage solution is connected to the refrigeration chamber, which is also connected to the storage cylinder. The evaporator includes a refrigeration inner sleeve and a refrigeration outer sleeve, with the outer sleeve wrapping around the outer side of the inner sleeve and sandwiched between them. The refrigerant pipe winding is disposed within the sandwich and tightly wound around the inner sleeve. The refrigeration chamber is disposed within the inner cavity of the inner sleeve, and an inner screw is disposed within the refrigeration chamber for scraping ice crystals from the first refrigeration inner wall and propelling them forward. The storage cylinder is disposed outside the evaporator, and an outer screw is disposed within the storage cylinder for stirring and propelling the ice crystals forward. The inner and outer screws are respectively connected to a power assembly.

[0010] As a specific design, the refrigeration chamber is an axially extending cylinder that is coaxially fitted with the internal screw. The rear end of the refrigeration chamber is provided with a liquid inlet that connects to the hopper, and the front end of the refrigeration chamber away from the liquid inlet is provided with an ice outlet.

When the hopper and evaporator are combined, the liquid delivery pipe is inserted into the groove, and the push rod extends into the liquid delivery chamber through the valve port and pushes open the valve body. At this time, the liquid delivery chamber is connected to the liquid inlet through the valve port. When the hopper and evaporator are separated, the push rod leaves the liquid delivery chamber, and the valve body closes the valve port by its own weight.

[0012] As another specific embodiment, the inner screw includes an inner drive rod and an inner spiral blade. The inner drive rod is coaxially engaged with the axially extending refrigeration cavity. The rear end of the inner drive rod is connected to the power assembly. The inner spiral blade is spirally connected to the inner drive rod on its inner side. The outer side of the inner spiral blade is infinitely close to the first refrigeration inner wall on the refrigeration inner sleeve.

[0013] As another specific embodiment, the outer screw includes an outer drive rod and an outer spiral blade. The outer drive rod is coaxially engaged with the axially extending storage cylinder. The outer drive rod is connected to the inner drive rod before the outer drive rod is connected to the outer drive rod. The front end of the outer spiral blade is connected to the outer drive rod, and the inner side of the outer spiral blade is at least partially infinitely close to the second cooling outer wall on the cooling jacket, while the outer side of the outer spiral blade is infinitely close to the inner wall of the cylinder inside the storage cylinder.

[0014] As another specific embodiment, the power assembly includes a drive motor fixedly mounted relative to the storage cylinder, the motor shaft of the drive motor being connected to a linkage component, a first drive bushing being provided at the rear end of the inner drive rod, the first drive bushing being inserted into the linkage component; the front end of the inner drive rod penetrating the cooling cavity and extending into the storage cylinder, a second drive bushing being provided at the rear end of the outer drive rod, the second drive bushing being inserted into the drive rod head at the front end of the inner drive rod; the power assembly synchronously drives the inner screw and the outer screw to rotate coaxially.

[0015] As another specific solution, the interlayer is a sleeve-shaped cavity with an opening on one side. The rear end of the interlayer is open and is sealed with a port plug. The refrigerant inlet pipe and refrigerant outlet pipe of the refrigerant pipe winding are led out to the outside through the rear end of the interlayer. The refrigerant pipe winding is close to the first refrigerant outer wall on the inner refrigerant sleeve, and there is a gap d between the refrigerant pipe winding and the second refrigerant inner wall on the outer refrigerant sleeve.

[0016] As another specific solution, the rear end of the refrigeration inner sleeve is closed, and the front end of the refrigeration inner sleeve is provided with a front cover, on which an ice outlet is provided. The refrigeration chamber is connected to the storage cylinder through the ice outlet. The front end of the refrigeration inner sleeve is connected to the front end of the refrigeration outer sleeve through a ring body, forming a closed end of the interlayer. The rear end of the refrigeration inner sleeve is sealed to the open end of the storage cylinder through a sealing cover assembly.

[0017] As another specific solution, the progressive slush preparation system also includes a tap assembly installed on the storage tank; the storage tank has an ice extraction port, which is opened or closed by the tap assembly.

[0018] As another specific solution, the cross-section of the refrigerant pipe winding is flat, and the inner side of the refrigerant pipe winding is in contact with the surface of the refrigeration inner sleeve.

[0019] The beneficial effects of this utility model are as follows:

[0020] Without increasing cooling power consumption, this invention improves cooling efficiency and shortens waiting time through technological modifications, achieving energy saving and meeting consumers' fast and varied needs, thus enhancing the product user experience. Therefore, the advantages of this utility model patent compared to existing technologies are: high cooling efficiency, almost no loss of cooling capacity, significantly reduced waiting time, and the ability to replenish raw materials (beverage solutions) at any time during use.

[0021] Specifically, this progressive slush preparation system improves refrigeration efficiency by modifying the structure of the evaporator:

[0022] The traditional refrigeration method changes the process from wrapping the beverage solution in the evaporator to wrapping the beverage solution in the evaporator. This effectively increases the heat exchange area of ​​the evaporator and improves the refrigeration efficiency. Secondly, it allows the beverage solution to completely absorb the cold energy inside the refrigeration chamber. Moreover, the beverage solution does not come into contact with any medium outside the evaporator (such as the storage tank), effectively avoiding heat exchange with the outside environment and thus almost eliminating the loss of cold energy.

[0023] The double-layered evaporator has two layers of stainless steel tubing, one inner and one outer. The refrigerant tubing is tightly wound around the outer wall of the inner refrigeration jacket (stainless steel tubing) inside the evaporator. Liquid refrigerant exchanges heat with the beverage solution inside the inner refrigeration jacket through the refrigerant tubing winding. After absorbing the heat from the beverage solution, the refrigerant changes phase into gas, which is discharged from the refrigerant outlet pipe at the rear end of the jacket. In this evaporator, the refrigerant tubing winding is wrapped around the outside of the beverage solution, allowing the cold energy to fully exchange heat with the beverage solution to form ice crystals, effectively avoiding cold energy loss.

[0024] The beverage solution to be cooled fills the refrigeration chamber. The feed inlet at the rear of the refrigeration chamber is connected to the feed hopper to continuously replenish the refrigeration chamber with beverage solution. The drive motor simultaneously drives the inner screw in the refrigeration chamber and the outer screw in the storage cylinder to rotate. The evaporator wraps the limited amount of beverage solution in the refrigeration chamber for cooling. The inner screw scrapes off the ice crystals that gradually form on the inner wall of the refrigeration chamber (the first refrigeration inner wall) and pushes them forward. When the ice slush accumulated at the front of the refrigeration chamber reaches a certain amount, the ice slush will flow out from the ice outlet at the front of the refrigeration chamber and enter the storage cylinder. The ice slush that enters the storage cylinder wraps the outer wall of the refrigeration jacket (i.e., the second refrigeration outer wall), and the coldness of the outer wall of the refrigeration jacket is used to freeze and keep the ice slush warm.

[0025] An ice outlet is located at the upper edge of the front end of the refrigeration chamber, and a feed inlet is located at the upper edge of the rear end. When the already formed slush inside the refrigeration chamber is pushed out by the internal screw and the liquid level of the beverage solution inside the refrigeration chamber gradually drops below the feed inlet, air enters the hopper through the feed inlet. The solution in the hopper flows into the refrigeration chamber through the feed inlet due to pressure loss. When the liquid level of the beverage solution in the refrigeration chamber exceeds the feed inlet, the beverage solution in the hopper stops flowing into the refrigeration chamber under atmospheric pressure. It can be seen that during the slush making process, the beverage solution in the hopper can be gradually replenished into the refrigeration chamber and gradually transformed into frozen slush inside the refrigeration chamber.

[0026] This evaporator concentrates the cooling energy on a limited amount of beverage solution within the refrigeration chamber. Since the cooling energy is almost not lost and is applied to a small amount of beverage solution, it can accelerate the freezing of the beverage solution into ice crystals, reducing the waiting time to more than half that of traditional machines. Furthermore, the V-shaped ice outlet and feed inlet at the front end of the refrigeration chamber ensure that frozen slush can be continuously produced. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] See Figures 1-11The progressive slush preparation system involved in this embodiment includes an evaporator 6 for refrigeration, a refrigeration chamber 12 for providing the necessary space for ice crystal production, and a storage tank 14 for freezing and storing ice crystals. The evaporator 6 is fixedly installed inside the storage tank 14. The evaporator 6 includes a refrigerant pipe winding 602 (such as a commonly used copper pipe winding) for introducing liquid refrigerant. The refrigerant rapidly evaporates and vaporizes into a low-temperature, low-pressure gaseous state within the refrigerant pipe winding 602, and is then discharged through the refrigerant outlet pipe 6022 of the refrigerant pipe winding 602. The heat exchange process of the refrigerant changing from a liquid to a gaseous state within the refrigerant pipe winding 602 causes the refrigerant pipe winding 602 to release cold energy outward. A hopper 9 for storing and supplying the beverage solution is connected to the rear end of the refrigeration chamber 12, and the front end of the refrigeration chamber 12 is connected to the storage tank 14. The evaporator 6 includes a refrigeration inner sleeve 601 and a refrigeration outer sleeve 603. In this embodiment, the refrigeration inner sleeve 601 and the refrigeration outer sleeve 603 are preferably stainless steel pipes with different diameters. The refrigeration outer sleeve 603 with a larger diameter is preferred. 3. A sleeve-shaped interlayer 13 is formed between the outer side of the smaller diameter refrigeration inner sleeve 601. The refrigerant pipe winding 602 is set in the interlayer 13 and tightly wound around the outer side of the refrigeration inner sleeve 601. The refrigeration chamber 12 is set in the inner cavity of the refrigeration inner sleeve 601. The cold energy generated by the refrigerant pipe winding 602 is released to the refrigeration chamber 12 through the refrigeration inner sleeve 601. The refrigeration chamber 12 is provided with an inner screw 5 for scraping off the ice crystals on the first refrigeration inner wall 6011 and pushing it forward. The first refrigeration inner wall 6011 is the inner wall of the refrigeration chamber 12. The evaporator 6 is set in the storage cylinder 14. The storage cylinder 14 is wrapped with the refrigeration outer sleeve 603. The ice in the storage cylinder 14 is wrapped outside the evaporator 6, thereby achieving freezing and heat preservation, making full use of the cold energy and avoiding waste. The storage cylinder 14 is provided with an outer screw 3 for stirring the ice crystals and pushing them forward. The inner screw 5 and the outer screw 3 are connected to the same set of power components through the transmission rod 501, so that the inner screw 5 and the outer screw 3 rotate simultaneously.

[0041] Furthermore, the refrigeration chamber 12 is an axially extending cylinder. The refrigeration chamber 12 is coaxially fitted with the inner screw 5. The rear end of the refrigeration chamber 12 is provided with a liquid inlet 607 that connects to the material hopper 9. The front end of the refrigeration chamber 12 away from the liquid inlet 607 is provided with an ice outlet 401. The refrigeration chamber 12 is connected to the storage tank 14 through the ice outlet 401. The liquid inlet 607 and the ice outlet 401 are respectively located at high positions, that is, the liquid inlet 607 and the ice outlet 401 are respectively located at the upper edge of their respective ends. This ensures that all the beverage solution entering the refrigeration chamber 12 is cooled to form slush and avoids leakage of beverage solution that has not formed slush.

[0042] Further, see Figure 4The bottom of the rear end of the hopper 9 is integrally formed with a downward-extending infusion pipe 902. A valve port 903 is provided at the lower end of the infusion pipe 902. An infusion chamber 16 is formed inside the infusion pipe 902, with its top connecting to the hopper 9 and its bottom connecting to the valve port 903. A valve body 17 is movably disposed within the infusion chamber 16. In this embodiment, the valve body 17 is a sphere that can sink in the beverage solution. The top of the rear end of the evaporator 6 (specifically, the refrigeration jacket 603) is integrally formed with a groove 605. Inside the groove 605 is an upward-extending push rod 606 and an inlet 607 connecting to the rear end of the refrigeration chamber 12. When the hopper 9 and the evaporator 6 are combined, the bottom of the infusion pipe 902 is sealed and inserted into the groove 605, and the push rod 606 extends into the infusion chamber 16 through the valve port 903. 6. The valve body 17 is opened, and the inlet 607 is connected to the liquid inlet 903 through the valve port 903, allowing the beverage solution in the hopper 9 to smoothly enter the refrigeration chamber 12. When the hopper 9 separates from the evaporator 6, the push rod 606 leaves the inlet 16, and the valve body 17 seals the valve port 903 by its own weight, preventing the beverage solution in the hopper 9 from leaking out. The detachable hopper 9 and storage tank 14 make it convenient for users to clean them. In addition to being able to disassemble the hopper 9 and storage tank 14 for individual cleaning, since the hopper 9, refrigeration chamber 12 and storage tank 14 are connected in sequence, this smoothie machine can also have a cleaning function. That is, by adding cleaning agent to the hopper 9 and activating the cleaning button on the control panel, each chamber can be cleaned in sequence, making it easy to operate.

[0043] Further, see Figure 11 The inner screw 5 includes an inner drive rod 501 and an inner spiral blade 502. The inner drive rod 501 is coaxially engaged with the axially extending refrigeration chamber 12. The rear end of the inner drive rod 501 is connected to the power assembly. The inner spiral blade 502 is spirally connected to the inner drive rod 501 on its inner side. The outer side of the inner spiral blade 502 is infinitely close to the first refrigeration inner wall 6011 on the refrigeration inner sleeve 601. The first refrigeration inner wall 6011 is the location for the conduction of cold energy in the refrigeration chamber 12. Therefore, when the beverage solution is cooled, it freezes into ice crystals and adheres to the first refrigeration inner wall 6011. When the inner screw 5 rotates, the outer side of the inner spiral blade 502 can effectively scrape off the ice shavings on the first refrigeration inner wall 6011 and push them forward. The ice shavings eventually leave the refrigeration chamber 12 through the ice outlet 401 and enter the storage tank 14 for storage. The refrigeration chamber 12 has a limited capacity for beverage solution, and the beverage solution is gradually pushed forward, allowing it to be refrigerated while being pushed forward, which greatly improves the efficiency of ice shavings production.

[0044] Further, see Figure 10The outer screw 3 includes an outer drive rod 301 and an outer spiral blade 302. The outer drive rod 301 is coaxially engaged with the axially extending storage cylinder 14. The outer drive rod 301 is connected to the front end of the inner drive rod 501. The front end of the outer spiral blade 302 is connected to the front end of the outer drive rod 301. The inner side of the outer spiral blade 302 is infinitely close to the second refrigeration outer wall 6032 on the refrigeration jacket 603, and the outer side of the outer spiral blade 302 is infinitely close to the inner wall 1401 of the cylinder below the cross-section of the storage cylinder 14, so as to more comprehensively propel the ice slush in the storage cylinder 14. In order to ensure the axial strength and rear end strength of the outer spiral blade 302, a side fixing bracket 303 is provided on the side of the outer spiral blade 302 and a rear fixing bracket 304 is provided at the rear end. The ice slush in the storage cylinder 14 wraps the evaporator 6. The cold energy on the surface of the evaporator 6 can be used for freezing and heat preservation of the ice slush, so that the cold energy is fully utilized and the effect of zero loss is achieved.

[0045] Furthermore, the power assembly includes a drive motor 8 fixedly mounted relative to the storage cylinder 14. The drive motor 8 is electrically connected to the control module on the smoothie machine. The motor shaft of the drive motor 8 is driven and inserted into the rear end of the linkage component 10. A first drive shaft sleeve 503 is provided at the rear end of the inner drive rod 501. The front end of the linkage component 10 passes through the rear end of the refrigeration inner sleeve 601 and inserts into the refrigeration chamber 12. The first drive shaft sleeve 503 is driven and inserted into the front end of the linkage component 10. The front end of the inner drive rod 501 passes through the refrigeration chamber 12 and extends into the storage cylinder 14, i.e., the inner... The front end of the transmission rod 501 passes through the front end of the refrigeration inner sleeve 601, and the rear end of the outer transmission rod 301 is provided with a second drive shaft sleeve 3011. The second drive shaft sleeve 3011 is connected to the transmission rod head 504 at the front end of the inner transmission rod 501. The power component synchronously drives the inner screw 5 and the outer screw 3 to rotate coaxially, so that the refrigeration chamber 12 continuously produces frozen slush into the storage tank 14. An equal amount of beverage solution is then added into the refrigeration chamber 12, so that the beverage solution can be added at any time during the refrigeration process, realizing uninterrupted slush production.

[0046] Further, see Figure 6 The interlayer 13 is a sleeve-shaped cavity with an opening on one side, meaning the front of the interlayer 13 is closed and the rear is open. The interlayer 13 is filled with a heat-insulating material, preferably a solid foaming agent. The rear end of the interlayer 13 is open and can be sealed with a port plug as needed. The refrigerant inlet pipe 6021 and refrigerant outlet pipe 6022 of the refrigerant pipe winding 602 are led out to the outside through the rear end of the interlayer 13. The structure is simple and reasonable. (See also...) Figure 7 The inner side of the refrigerant pipe winding 602 is closely attached to the first refrigeration outer wall 6012 on the refrigeration inner sleeve 601. There is a gap d between the refrigerant pipe winding 602 and the second refrigeration inner wall 6031 on the refrigeration outer sleeve 603. This gap d can be filled with solid filler to form a heat insulation layer, which can effectively prevent the cold energy from being directly conducted to the refrigeration outer sleeve 603 and causing excessive loss.

[0047] Furthermore, the rear end of the refrigeration inner sleeve 601 is closed, and a corresponding central hole is provided on the closed end for assembling the aforementioned linkage component 10. A sealing element and a bearing component are provided between the refrigeration inner sleeve 601 and the linkage component 10. The front end of the refrigeration inner sleeve 601 is open and sealed with a front end cover 4, so that the refrigeration chamber 12 is closed from front to back. The top of the front end cover 4 is provided with an upward-facing V-shaped ice outlet 401. The refrigeration chamber 12 is connected to the storage cylinder 14 through the ice outlet 401, and the ice in the refrigeration chamber 12 enters the storage cylinder 14 through the ice outlet 401. The front end of the refrigeration inner sleeve 601 is connected to the front end of the refrigeration outer sleeve 603 through a ring 604, forming the closed end of the interlayer 13. In this embodiment, the refrigeration inner sleeve 601, the ring 604 and the refrigeration outer sleeve 603 are formed by stamping and welding of stainless steel pipes or plates. The rear end of the refrigeration inner sleeve 601 is sealed to the open end of the rear side of the storage cylinder 14 through a sealing cover assembly 7. The front end of the storage cylinder 14 is closed to ensure the airtightness of the storage cylinder 14.

[0048] Furthermore, this progressive slush preparation system also includes a tap assembly 1 located at the front end of the storage cylinder 14; an ice extraction port 1402 is provided at the lower edge of the front end of the storage cylinder 14, and the ice extraction port 1402 is opened or closed by the tap assembly 1; the inner screw 5 and the outer screw 3 work continuously under the action of the power assembly, and the handle of the tap assembly 1 can be turned at any time when there is slush in the storage cylinder 14 to release the already formed frozen slush through the ice extraction port 1402.

[0049] Furthermore, the inner side of the cross-section of the refrigerant pipe winding 602 is flat, ensuring perfect contact between the inner side of the refrigerant pipe winding 602 and the surface of the refrigeration inner sleeve 601. This effectively increases the contact area between the refrigerant pipe winding 602 and the refrigeration inner sleeve 601, thereby greatly improving the cold energy conduction effect, increasing the efficiency of ice slush production, and further reducing cold energy loss.

[0050] The table below compares the parameters of a traditional smoothie maker with those of the smoothie maker in this embodiment:
