Description

Technical Field

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

[0002] The evaporator heat transfer in commercially available slush machines relies on contact between the outer surface of the evaporator tubes and the inner surface of the refrigeration drum. Due to the small contact area, and even gaps that cannot be overcome, poor contact occurs, resulting in low heat transfer efficiency. Furthermore, the temperature difference between the refrigerant inlet and outlet of the evaporator tubes causes uneven surface temperature on the refrigeration drum, leading to significant differences in the temperature of the surface frost layer, which severely affects the slush-scraping performance. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, this utility model provides a slush machine and slush device that produces uniformly mixed slush.

[0004] An ice-making device for an ice-making machine, assembled in the ice-making chamber of the ice-making machine, is characterized by comprising a refrigeration tank, evaporator pipes, a cooling agent, a scraper, and a drive shaft. The refrigeration tank is a closed annular barrel-shaped structure formed by inner and outer double-layered walls. The evaporator pipes are partially sealed within the closed annular space of the refrigeration tank, and the gap between the closed annular space of the refrigeration tank and the evaporator pipes is filled with a cooling agent, which has the characteristics of antifreeze and rapid cooling. The drive shaft drives the scraper to rotate and scrape off the frost on the refrigeration tank.

[0005] Furthermore, the evaporator piping is spirally wound around the refrigeration barrel axially between the inner and outer double-layer barrel walls.

[0006] Furthermore, the scraper includes an outer scraper and / or an inner scraper, one end of the drive shaft is connected to a drive motor, and the other end passes through the refrigeration barrel along the axis of the refrigeration barrel and is driven to connect with the outer scraper and / or the inner scraper.

[0007] Furthermore, the outer surface of the outer barrel wall of the refrigeration barrel is defined as the outer cold-conducting surface, and the inner surface of the inner barrel wall is defined as the inner cold-conducting surface. The inner and outer scrapers are spiral scrapers, with their spiral parts respectively sleeved on the inner and outer cold-conducting surfaces of the refrigeration barrel and extending spirally along the inner and outer cold-conducting surfaces.

[0008] Furthermore, when designed with only an external scraper, the refrigeration barrel is filled with heat-insulating material between the inner wall of the inner barrel and the drive shaft, and the external scraper is installed on the drive shaft at a position corresponding to one end of the refrigeration barrel away from the drive motor.

[0009] Furthermore, when designed for simultaneous internal and external scraping, the refrigeration barrel has a through hole extending axially along its inner cooling surface. The inner scraper is housed within the through hole, and its spiral portion extends spirally along the inner cooling surface of the refrigeration barrel. The outer scraper is mounted on the drive shaft at a position corresponding to one end of the refrigeration barrel, away from the drive motor. The inner scraper is mounted on the drive shaft at a position corresponding to the other end of the refrigeration barrel, near the drive motor.

[0010] Furthermore, a connecting part is provided at one end of the refrigeration barrel, and the refrigeration barrel is assembled into the ice-making chamber of the ice-making machine through the connecting part. The through hole of the refrigeration barrel is connected to the ice-making chamber of the ice-making machine at the assembly point of the refrigeration barrel and the ice-making chamber of the ice-making machine through the connecting part.

[0011] Furthermore, the outer scraper and the inner scraper have opposite spiral directions.

[0012] Furthermore, the inner scraper is spiraled towards the refrigeration tank connection, while the outer scraper is spiraled away from the refrigeration tank connection.

[0013] A smoothie maker is also provided, wherein the smoothie maker chamber is equipped with any of the smoothie maker devices described above.

[0014] The beneficial effects of this utility model are as follows:

[0015] The cooling energy within the evaporator pipes is evenly transferred to the refrigeration tank via a refrigerant, resulting in a uniformly low temperature on the tank's cooling surface. Beverages in contact with the tank condense evenly on both the inner and outer cooling surfaces. Then, the condensation is further agitated and scraped by spiral inner and outer scrapers, creating slush. This continuous operation ensures a constant supply of slush. Simultaneously, the uniform temperature of the cooling surface and the consistent temperature and thickness of the frost minimize damage to the scrapers.

[0016] The system features an inner and an outer scraper, with the two scrapers spiraling in opposite directions. This allows the smoothie and beverage to circulate between the cooling tank's through-hole and the smoothie machine's ice chamber, driven by both scrapers. This increases the amount of smoothie produced and makes the smoothie more uniform. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0028] In the description of this utility model, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating the description of the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Example 1

[0029] like Figure 1-4 As shown, an ice-making device for an ice slush machine is assembled inside the ice-making chamber 10 of the ice slush machine. It includes a refrigeration tank 3, evaporator pipes 5, a refrigerant 7, an outer scraper 2-1, and a drive mechanism. The refrigeration tank 3 is a closed annular barrel-shaped structure formed by inner and outer double-layered walls. The evaporator pipes 5 are partially sealed within the closed annular space of the refrigeration tank, spirally wound around the inner and outer double-layered walls within the closed annular space of the refrigeration tank 3. The inlet pipe 5-1 and outlet pipe 5-2 of the evaporator pipes are connected to a compressor and a condenser to form a refrigeration circuit. A liquid inlet pipe 3-1 is provided above one end of the refrigeration tank 3, corresponding to the closed annular space. The end of the liquid inlet pipe 3-1 is equipped with a pipe cap 3-2. The refrigerant 7 is filled into the closed annular space of the refrigeration tank 3 from the liquid inlet pipe 3-1. The refrigerant 7 has the characteristics of antifreeze and good cold transfer effect.

[0030] The driving mechanism includes a drive motor 6 and a drive shaft 1. One end of the drive shaft 1 is connected to the drive motor 6, and the other end passes through the refrigeration tank 3 along its axis and is driven to connect with the outer scraper 2-1. The outer scraper 2-1 is mounted on the drive shaft 1 at a position corresponding to one end of the refrigeration tank 3, away from the drive motor 6. The outer surface of the outer wall of the refrigeration tank 3 is defined as the outer cold-conducting surface 3-4, and the inner surface of the inner wall is defined as the inner cold-conducting surface 3-5. The outer scraper 2-1 is a spiral scraper, with its spiral part sleeved on the outer cold-conducting surface 3-4 of the refrigeration tank and extending spirally along the outer cold-conducting surface. When the drive shaft 1 drives the outer scraper 2-1 to rotate based on the drive motor 6, it scrapes off the ice and slush on the outer cold-conducting surface 3-4 of the refrigeration tank 3.

[0031] The refrigeration tank 3 is filled with heat insulation material 4 between the inner side of the inner cold-conducting surface 3-5 and the drive shaft 1. This prevents the cold energy from being transferred to the air through the inner cold-conducting surface 3-5 of the refrigeration tank. Instead, it can only be transferred unidirectionally through the outer cold-conducting surface 3-4 of the refrigeration tank to the beverage products that need condensation.

[0032] The refrigeration barrel 3 is provided with a connecting part 3-6 on one end. After the refrigeration barrel 3 is connected to the drive motor mounting base through the connecting part 3-6, it is assembled into the ice chamber 10 of the ice slush machine.

[0033] Working process: The cold energy in the evaporator pipes is evenly transferred to the refrigeration tank through the refrigerant, causing the outer cooling surface of the refrigeration tank to have a low and uniform temperature. The beverage in contact with the refrigeration tank condenses evenly on the outer cooling surface of the refrigeration tank, and then is scraped and stirred by the spiral outer scraper to form slush. By working continuously, slush can be produced continuously and evenly. Example 2

[0034] like Figure 1 and Figure 5-9 As shown, an ice-making device for an ice slush machine is assembled inside the ice-making chamber 10 of the ice slush machine. It includes a refrigeration tank 3, evaporator pipes 5, a refrigerant 7, a drive mechanism, an outer scraper 2-1, and an inner scraper 2-2. The refrigeration tank 3 is a closed annular barrel-shaped structure formed by inner and outer double-layered walls. The evaporator pipes 5 are partially sealed within the closed annular space of the refrigeration tank 3 and spirally wound around the inner and outer double-layered walls axially within the refrigeration tank 3. The inlet pipe 5-1 and outlet pipe 5-2 of the evaporator pipes are connected to a compressor and a condenser to form a refrigeration pipeline. A liquid inlet pipe 3-1 is provided above one end of the refrigeration tank 3, corresponding to the closed annular space. The end of the liquid inlet pipe 3-1 is equipped with a pipe cap 3-2. The refrigerant 7 is filled into the closed annular space of the refrigeration tank 3 from the liquid inlet pipe 3-1. The refrigerant 7 has the characteristics of antifreeze and good cold transfer effect.

[0035] The outer surface of the outer barrel wall of the refrigeration barrel 3 is defined as the outer cooling surface 3-4, and the inner surface of the inner barrel wall is defined as the inner cooling surface 3-5. The refrigeration barrel 3 has a through hole 3-3 extending along its axial direction based on the inner cooling surface 3-5.

[0036] The outer scraper 2-1 is a spiral scraper, with its spiral part sleeved on the outer cooling surface 3-4 of the refrigeration tank and extending spirally along the outer cooling surface. The inner scraper 2-2 is housed in the through hole, with its spiral part extending spirally along the inner cooling surface 3-5 of the refrigeration tank.

[0037] The driving mechanism includes a drive motor 6 and a drive shaft 1. One end of the drive shaft 1 is connected to the drive motor 6, and the other end passes through a through hole along the axis of the refrigeration tank 3, connecting to the inner scraper 2-2 and the outer scraper 2-1 respectively. The outer scraper 2-1 is mounted on the drive shaft 1 at a position corresponding to one end of the refrigeration tank 3, away from the drive motor 6. The inner scraper 2-2 is mounted on the drive shaft 1 at a position corresponding to the other end of the refrigeration tank 3, near the drive motor 6. When the drive shaft 1 drives the inner and outer scrapers to rotate based on the drive motor 6, it scrapes off the ice and slush on the inner cooling surface 3-5 and the outer cooling surface 3-4 of the refrigeration tank.

[0038] A connecting part 3-7 is provided on one end of the refrigeration barrel 3. After the refrigeration barrel 3 is connected to the drive motor mounting base through the connecting part 3-7, it is assembled into the ice-making chamber 10 of the slush machine. A plurality of supporting ribs 3-8 are evenly arranged around the connecting part 3-7. The adjacent supporting ribs 3-8 are spaced apart. The through hole 3-3 of the refrigeration barrel is connected to the ice-making chamber 10 of the slush machine through the spaced-out holes.

[0039] The inner scraper 2-2 is spiraled toward the refrigeration barrel connection part 3-7, and the outer scraper 2-1 is spiraled away from the refrigeration barrel connection part 3-7.

[0040] Working process: The cold energy generated by the evaporator is evenly transferred to the refrigeration tank through the refrigerant, resulting in a low and uniform temperature on both the inner and outer cooling surfaces of the tank. Beverages in contact with the tank condense evenly on these surfaces, forming frost. This frost is then scraped and stirred by the outer and inner scrapers to create slush. The inner and outer scrapers are arranged in opposite spiral directions, allowing the slush and beverage to circulate between the refrigeration tank's through-hole and the slush machine's ice chamber under the dual drive of the scrapers. This increases the amount of slush produced and makes it more uniform. Simultaneously, the uniform temperature of the inner and outer cooling surfaces of the tank, along with the uniform temperature and thickness of the frost, reduces the risk of damage to the ice blades.

[0041] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
