Description

Technical Field

[0001] The invention relates to the field of refrigeration household appliances, in particular to a progressive smoothie preparation system of a smoothie machine. Background Art

[0002] A smoothie machine, also known as a snow melt machine, is a cold drink device that freezes liquid beverages such as cola, wine, coffee, soda, juice, chocolate, and milk into a cool, refreshing, snow-like drink. The refrigeration components of a smoothie machine include a compressor, condenser, and evaporator. Both commercial and home smoothie machines on the market immerse the evaporator in a beverage solution, forming ice crystals through heat exchange between the evaporator's outer wall and the beverage solution in the solution tank. However, this refrigeration method also has obvious drawbacks: Large loss of cooling capacity transfer: During the refrigeration process, the beverage solution in the solution tank continuously absorbs heat from the external environment through the outer wall of the solution tank, which will greatly neutralize the cooling capacity transferred by the evaporator, resulting in cooling capacity loss, which directly affects the cooling efficiency of the smoothie machine; Low refrigeration efficiency: The core of heat exchange in the evaporator is the tightly wound refrigerant tube winding. The current refrigerant tube winding process cannot solve the fundamental problem of the refrigerant tube winding's outer surface not perfectly fitting with the inner wall of the evaporator shell. The lack of contact surface results in a loss of heat exchange area, which directly affects the conduction of cooling energy and significantly reduces the cooling efficiency of the beverage solution. Time-consuming and energy-consuming: Traditional smoothie machines work by freezing all the beverage solutions exceeding 2 liters in the solution tank at once. The excessive amount of beverage solution frozen at one time results in a long time consumption. In addition, the 360-degree outer wall of the solution tank absorbs heat over a large area, which directly affects the refrigeration efficiency and consumes a lot of energy. Traditional smoothie machines often need to be turned on for more than an hour to make smoothie cold drinks, and the beverage solution cannot be added to the machine during the smoothie making process. It can be seen that existing smoothie machines are time-consuming and energy-consuming, and are not flexible enough to use. They cannot adapt to various sudden cold drink needs and the user experience is poor.

[0003] With the improvement of living standards, more and more consumers hope to enjoy the fun of quickly making smoothies and cold drinks at home. However, traditional smoothie machines for making smoothies are time-consuming and electricity-consuming. Therefore, how to design a smoothie machine refrigeration system with high efficiency, low energy consumption, and the ability to replenish raw materials at any time during use has become a technical problem that needs to be solved urgently.

[0008] As another specific solution, the inner screw includes an inner transmission rod and an inner spiral leaf. The inner transmission rod is coaxially matched with the axially extending refrigeration chamber. The rear end of the inner transmission rod is connected to the power component. The inner side of the inner spiral leaf is spirally connected to the inner transmission rod, and the outer side of the inner spiral leaf is infinitely close to the first refrigeration inner wall on the refrigeration inner sleeve.

[0009] As another specific scheme, the outer screw includes an outer transmission rod and an outer spiral leaf. The outer transmission rod is coaxially matched with the axially extending storage cylinder. The outer transmission rod is connected to the front of the inner transmission rod, and the front end of the outer spiral leaf is connected to the outer transmission rod. The inner side of the outer spiral leaf is at least partially infinitely close to the second refrigeration outer wall on the refrigeration jacket, and the outer side of the outer spiral leaf is infinitely close to the inner wall of the cylinder body in the storage cylinder.

[0014] As another specific solution, the cross section of the tube body in the refrigerant tube winding is flat, and the inner side of the refrigerant tube winding is in surface contact with the refrigeration inner sleeve.

[0015] The beneficial effects of the present invention are as follows: Without increasing the power consumption of refrigeration, the refrigeration efficiency is improved through technical transformation, and the waiting time is shortened, so as to achieve the purpose of saving electricity and energy, meet the fast and changing needs of consumers, and improve the product usage experience; it can be seen that the advantages of the patent of this invention over the existing technology are: high refrigeration efficiency, almost no cooling loss, can greatly shorten the waiting time, and can replenish raw materials (drink solution) at any time during use.

[0016] Specifically, the progressive smoothie preparation system improves refrigeration efficiency by improving the structure of the evaporator: The traditional refrigeration method is changed from wrapping the evaporator with a beverage solution to wrapping the beverage solution in the evaporator. This can effectively increase the heat exchange area of ​​the evaporator and improve the refrigeration efficiency. Secondly, the beverage solution can completely absorb the cold energy in the refrigeration chamber. In addition, the beverage solution does not come into contact with the medium outside the evaporator (such as the storage tank), effectively avoiding heat exchange with the outside world and causing almost no cooling loss. The double-layer evaporator with a sleeve-like structure is a stainless steel tube structure with two layers of inner and outer layers. The refrigerant tube windings are tightly wrapped around the outer wall of the refrigeration inner jacket (stainless steel tube) in the evaporator. The liquid refrigerant passes through the refrigerant tube windings to exchange heat with the beverage solution in the refrigeration inner jacket and cools it. After absorbing the heat of the beverage solution, it changes phase into gas, which is discharged from the refrigerant outlet pipe at the rear end of the interlayer. In this evaporator, the refrigerant tube windings are 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. The beverage solution to be cooled fills the refrigeration chamber, and the feed port at the rear end of the refrigeration chamber is connected to the silo to continuously replenish the beverage solution to the refrigeration chamber. 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 around the limited amount of beverage solution in the refrigeration chamber to cool it. The inner screw scrapes off the ice crystals gradually formed on the inner wall of the refrigeration chamber (the first refrigeration inner wall) and pushes them forward. When the amount of smoothie accumulated at the front end of the refrigeration chamber reaches a certain amount, the smoothie will flow out of the ice outlet at the front end of the refrigeration chamber into the storage cylinder. The cold smoothie entering the storage cylinder wraps around the outer wall of the refrigeration jacket (i.e., the second refrigeration outer wall), and the cold energy of the refrigeration jacket outer wall is used to freeze and keep the smoothie warm. An ice outlet is provided at the upper edge of the front end of the refrigeration chamber, and a feed port is provided at the upper edge of the rear end. When the formed smoothie in the refrigeration chamber is pushed out by the inner screw and the level of the beverage solution in the refrigeration chamber gradually drops below the feed port, air enters the hopper through the feed port, and the solution in the hopper flows into the refrigeration chamber through the feed port due to pressure loss. When the level of the beverage solution in the refrigeration chamber exceeds the feed port, the beverage solution in the hopper stops flowing into the refrigeration chamber under the action of atmospheric pressure. It can be seen that during the process of making smoothies, the beverage solution in the hopper can be gradually added to the refrigeration chamber and gradually converted into frozen smoothies in the refrigeration chamber. This evaporator concentrates the cooling energy on the limited beverage solution in the refrigeration chamber. Since there is almost no loss of cooling energy and the cooling energy is applied to a smaller amount of beverage solution, the freezing speed of the beverage solution into ice crystals can be accelerated, reducing the waiting time to more than half of that of traditional machines. In addition, the V-shaped ice outlet and feed port at the front of the refrigeration chamber ensure that the frozen smoothie can be produced continuously. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] See also Figures 1-11The progressive smoothie preparation system involved in this embodiment includes an evaporator 6 for refrigeration, a refrigeration chamber 12 that provides the required space for ice crystal production, and a storage cylinder 14 for freezing and storing ice crystals; the evaporator 6 is fixedly arranged in the storage cylinder 14; the evaporator 6 includes a refrigerant tube winding 602 (such as a commonly used copper tube winding) for introducing liquid refrigerant, the refrigerant rapidly evaporates and vaporizes into a low-temperature and low-pressure gas in the refrigerant tube winding 602, and is then discharged through the refrigerant outlet pipe 6022 of the refrigerant tube winding 602. The heat exchange process of the refrigerant from liquid to gas in the refrigerant tube winding 602 causes the refrigerant tube winding 602 to release cold energy outward; the silo 9 for storing and supplying 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 cylinder 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, and the refrigeration outer sleeve 603 with a larger diameter is preferably stainless steel pipes with a larger diameter. 3 is wrapped around the outside of the refrigeration inner sleeve 601 with a smaller diameter and a sleeve-shaped interlayer 13 is provided between each other. The refrigerant tube winding 602 is arranged in the interlayer 13 and tightly wound around the outside of the refrigeration inner sleeve 601; the refrigeration chamber 12 is arranged in the inner cavity of the refrigeration inner sleeve 601, and the cold energy generated by the refrigerant tube 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 ice crystals on the first refrigeration inner wall 6011 and pushing them forward. The first refrigeration inner wall 6011 is the inner wall of the refrigeration chamber 12; the evaporator 6 is arranged in the storage cylinder 14, and the storage cylinder 14 wraps the refrigeration outer sleeve 603. The smoothie in the storage cylinder 14 is wrapped around the outside of the evaporator 6, thereby being frozen and kept warm, making more effective use of the cold energy and avoiding waste. The storage cylinder 14 is provided with an outer screw 3 for stirring and pushing the ice crystals 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.

[0031] Furthermore, the refrigeration chamber 12 is an axially extended cylinder, and the refrigeration chamber 12 is coaxially matched with the inner screw 5. A liquid inlet 607 connected to the hopper 9 is provided at the rear end of the refrigeration chamber 12, and an ice outlet 401 is provided at the front end of the refrigeration chamber 12 away from the liquid inlet 607. The refrigeration chamber 12 is connected to the storage cylinder 14 through the ice outlet 401. The liquid inlet 607 and the ice outlet 401 are respectively arranged at high positions, that is, the liquid inlet 607 and the ice outlet 401 are respectively arranged at the upper edge of their ends. This can ensure that all the beverage solution entering the refrigeration chamber 12 can be refrigerated to form smoothies, and prevent the beverage solution that has not formed smoothies from leaking.

[0032] Further, see Figure 4, the bottom of the rear end of the hopper 9 is integrally formed with an infusion tube 902 extending downward, and a valve port 903 is opened at the lower end of the infusion tube 902. An infusion cavity 16 is formed on the inside of the infusion tube 902, which is connected to the hopper 9 at the top and the valve port 903 at the bottom. A valve body 17 is movably provided in the infusion cavity 16. The valve body 17 in this embodiment is a sphere that can be sunk in the beverage solution; a groove 605 is integrally formed on the top of the rear end of the evaporator 6 (specifically, the refrigeration jacket 603), and an upwardly extending ejector rod 606 and a liquid inlet 607 connected to the rear end of the refrigeration cavity 12 are provided inside the groove 605; when the hopper 9 and the evaporator 6 are combined, the bottom of the infusion tube 902 is sealed and plugged into the groove 605, and the ejector rod 606 extends into the infusion cavity 1 through the valve port 903. 6 and push open the valve body 17. At this time, the infusion chamber 16 is connected to the liquid inlet 607 through the valve port 903, and the beverage solution in the hopper 9 can smoothly enter the refrigeration chamber 12; when the hopper 9 is separated from the evaporator 6, the push rod 606 leaves the infusion chamber 16, and the valve body 17 uses its own weight to close the valve port 903 to prevent the beverage solution in the hopper 9 from leaking out; the detachable hopper 9 and storage cylinder 14 are convenient for users to clean them; in addition to being able to disassemble the hopper 9 and the storage cylinder 14 for separate cleaning, since the hopper 9, the refrigeration chamber 12 and the storage cylinder 14 are connected in sequence, the present smoothie machine can add a cleaning function, that is, by adding cleaning agent to the hopper 9 and starting the cleaning button on the control panel, each chamber can be cleaned in sequence and in an orderly manner, which is easy to operate.

[0033] Further, see Figure 11 The inner screw 5 includes an inner transmission rod 501 and an inner spiral blade 502.

The inner side of the inner spiral blade 502 is spirally connected to the inner transmission rod 501. 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 cold conduction in the refrigeration chamber 12. Therefore, the beverage solution is cooled and forms 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 smoothie on the first refrigeration inner wall 6011 and push it forward. The smoothie eventually leaves the refrigeration chamber 12 through the ice outlet 401 and enters the storage cylinder 14 for storage. The capacity of the beverage solution that can be accommodated in the refrigeration chamber 12 is limited, and the beverage solution is gradually pushed forward, so that it can be cooled while being pushed, which greatly improves the efficiency of smoothie production.

[0034] Further, see Figure 10The outer screw 3 includes an outer transmission rod 301 and an outer spiral leaf 302. The outer transmission rod 301 is coaxially matched with the axially extended storage cylinder 14. The outer transmission rod 301 is transmission-connected to the front end of the inner transmission rod 501, and the front end of the outer spiral leaf 302 is connected to the front end of the outer transmission rod 301. The inner side of the outer spiral leaf 302 and the corresponding part of the evaporator 6 are infinitely close to the second refrigeration outer wall 6032 on the refrigeration jacket 603, and the outer side of the outer spiral leaf 302 is infinitely close to the cylinder inner wall 1401 below the cross section of the storage cylinder 14, so as to more comprehensively promote the smoothie in the storage cylinder 14; in order to ensure the axial strength and rear end strength of the outer spiral leaf 302, a side fixing bracket 303 is provided on the side of the outer spiral leaf 302 and a rear fixing bracket 304 is provided at the rear end; the smoothie in the storage cylinder 14 wraps the evaporator 6, and the cold energy on the surface of the evaporator 6 can be used for freezing and keeping warm the smoothie, so that the cold energy is fully utilized to achieve a zero loss effect.

The interlayer 13 is filled with a filler with heat-insulating properties, which is preferably a solid foaming agent. The rear end of the interlayer 13 is open and can be sealed with a port plug according to actual needs. The refrigerant inlet pipe 6021 and the 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 Figure 7 The inner side of the refrigerant tube winding 602 is close to the first refrigeration outer wall 6012 on the refrigeration inner sleeve 601, and there is a distance d between the refrigerant tube winding 602 and the second refrigeration inner wall 6031 on the refrigeration outer sleeve 603.
