[0002] A Chinese patent with publication number CN 222335832U discloses a multi-functional tea bar machine, including a casing and a compressor and condenser disposed within the casing. The casing also contains an ice-making component, a cold chamber, and a refrigerator. The ice-making component includes a water tank, an ice basket disposed within the water tank, a water collection trough, and an ice-making evaporator disposed corresponding to the water collection trough. The water collection trough is connected to the water tank and is disposed above the ice basket. A first evaporator is disposed within the cold chamber. A second evaporator is disposed within the refrigerator. The compressor and condenser are respectively connected to the ice-making evaporator, the first evaporator, and the second evaporator, so that the ice-making component is used for making ice, the cold chamber is used for cooling water, and the refrigerator is used for refrigeration.

[0003] However, the aforementioned tea bar machine has the following drawbacks: the cold water in this tea bar machine is entirely produced by the cold tank alone, resulting in low cooling efficiency. The temperature of the cold water can usually be as low as 3-6°C. At this point, the temperature inside the cold tank is usually below zero, which makes it easy for ice to form on the surface of the cold tank, especially at the bottom, leading to blockage of the water supply pipeline. This needs to be improved. Utility Model Content

[0018] A further feature of this invention is that the bottom wall of the inner cavity of the water tank forms a concave arc-shaped surface, and the return water hole is located at the lowest point of the arc-shaped surface.

[0019] By adopting the above technical solution, the concave arc surface is conducive to the accumulation and drainage of water in the return water tank.

[0020] A further feature of this invention is that it includes a flipping mechanism, which includes a drive motor fixed to the side wall of the ice receiving frame, the drive motor being used to drive the ice making box to flip relative to the water return chamber.

[0021] By adopting the above technical solution, the purpose of emptying and resetting the ice container is achieved by using the forward and reverse rotation of the output shaft of the drive motor.

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] A cold-tank antifreeze structure for a tea-drinking machine, such as Figures 1-4 As shown, the device includes a main body 1 of a water purifier. The main body 1 contains a cold tank 2 and an ice-making module. The ice-making module includes a water return chamber 3 and an ice-making box 4, with the ice-making box 4 housed within the water return chamber 3. The cold tank 2 has a first evaporator 21, and the ice-making box 4 has a second evaporator 41, which is U-shaped. The main body 1 also includes a compression refrigeration module 5 for supplying refrigerant to the first evaporator 21 and the second evaporator 41. The tank 2 is equipped with a circulation pump 22. The inlet of the circulation pump 22 is connected to the cold tank 2, and the outlet of the circulation pump 22 is connected to the ice box 4 through a water supply pipe 221 to fill the ice box 4 with water. A return water structure is connected between the return water chamber 3 and the cold tank 2. The water in the return water chamber 3 flows back to the cold tank 2 through the return water structure. Several refrigeration columns 411 extend from the side wall of the first refrigeration evaporator 21 toward the ice box 4. The refrigeration columns 411 are partially or completely inserted into the inner cavity of the ice box 4.

[0034] like Figures 1-3 As shown, the water return chamber 3 has an ice pouring port 30. The water return chamber 3 includes a water tank 31 and a baffle 32 on the water tank 31. A clearance gap 321 is left between the ice maker 4 and the baffle 32. The projection area of ​​the ice maker 4 in the height direction of the main body 1 of the water purifier falls into the inner cavity of the water tank 31, so that when the water in the ice maker 4 overflows, the overflowing water can be completely caught by the water return chamber 3 to prevent leakage. The water return structure includes a water return pipe 33. The bottom of the water tank 31 has a water return hole 311. The water inlet end of the water return pipe 33 is connected to the water return hole 311, and the water outlet end of the water return pipe 33 is connected to the cold tank 2, so that the water in the water tank 31 can be quickly discharged into the cold tank 2 through the water return hole 311. The main body 1 of the water purifier has an ice receiving frame 6 for storing ice cubes. The ice receiving frame 6 includes a storage container. The ice chamber 61 and the ice-making chamber 62 located above the ice storage chamber 61 are provided in the ice-making chamber 62. The ice box 4 and the water return chamber 3 are located in the ice-making chamber 62. An installation space 63 is formed between the lower part of the ice-making chamber 62 and the side of the ice storage chamber 61. The water return pipe 33 is located in the installation space 63, which is conducive to the installation, disassembly and replacement of the water return pipe 33, making the internal space arrangement of this utility model more reasonable. The bottom wall of the inner cavity of the water tank 31 forms a concave arc surface. The water return hole 311 is opened at the lowest point of the arc surface. The concave arc surface is conducive to the accumulation and drainage of water in the water return chamber 3. In this embodiment, an air pressure balance pipe 25 is connected between the top of the cold tank 2 and the ice receiving frame 6 to balance the air pressure between the cold tank 2 and the ice receiving frame 6, so that the water in the water return chamber 3 can flow back to the cold tank 2 smoothly through the water return pipe 33.

[0035] like Figure 3As shown, it also includes a flipping mechanism, which includes a drive motor 64 fixed to the side wall of the ice receiving frame 6. The drive motor 64 is used to drive the ice making box 4 to flip relative to the return water tank 3. The forward and reverse rotation of the output shaft of the drive motor 64 is used to realize the purpose of emptying and resetting the ice in the ice making box 4. An ice-flipping plate 42 is provided on the side of the ice making box 4 near the ice emptying port 30. A water passage gap 421 is left between the ice-flipping plate 42 and the inner wall of the return water tank 3. Several water passage holes 422 are opened on the ice-flipping plate 42. The rotation of the ice making box 4 drives the ice-flipping plate 42 to rotate synchronously, thereby realizing the ice-scraping action of the ice in the return water tank 3. The water passage gap 421 and the water passage holes 422 allow water to flow through and be collected by the return water tank 3.

[0036] like Figure 2 and Figure 4 As shown, a water outlet sleeve 23 is provided on the side wall near the bottom of the cold tank 2. The inlet end of the circulation pump 22 is sealed to the water outlet sleeve 23. Since the cold water with a lower temperature in the cold tank 2 has a higher density, it will sink to the bottom of the cold tank 2. By connecting the water outlet sleeve 23 to the bottom of the cold tank 2, the circulation pump 22 can preferentially draw the cold water with a lower temperature in the cold tank 2. The first refrigeration evaporator 21 is spirally coiled in the inner cavity of the cold tank 2. The top of the cold tank 2 is provided with a water inlet connector 24. The outlet end of the return water pipe 33 is connected to the water inlet connector 24. The water inlet connector 24 is partially or entirely located in the vertical projection area of ​​the first refrigeration evaporator 21 in the main body 1 of the water purifier. This allows the cold water that flows back to the cold tank 2 through the return water structure and the water inlet connector 24 to drip directly onto the vicinity of the first refrigeration evaporator 21, thereby improving the cooling rate of the water source flowing back to the cold tank 2 through the return water structure.

[0037] The basic working principle of this utility model is as follows: A cold tank 2 and an ice-making module are provided inside the main body 1 of the water purifier.

The main body 1 of the water purifier also has a compression refrigeration module 5 for providing refrigerant to the first refrigeration evaporator 21 and the second refrigeration evaporator 41. The cold tank 2 is equipped with a circulation pump 22. The inlet end of the circulation pump 22 is connected to the cold tank 2, and the outlet end of the circulation pump 22 is connected to the ice-making box 4. A water return structure connects the water return chamber 3 and the cold tank 2, allowing water in the water return chamber 3 to flow back into the cold tank 2 through the water return structure. The refrigerant generated by the compression refrigeration module 5 is simultaneously supplied to the first refrigeration evaporator 21 and the second refrigeration evaporator 4. 1. The first refrigeration evaporator 21 is used to cool the water in the cold tank 2. The cold water prepared in the cold tank 2 is transported to the ice box 4 by the circulation pump 22. At this time, the second refrigeration evaporator 41 in the ice box 4 cools the cold water in the ice box 4 again. The cold water that has been cooled twice in the ice box 4 gradually fills the ice box 4 and falls into the return water tank 3. The cold water in the return water tank 3 flows back to the cold tank 2 through the return water structure. This cycle forms a dynamic water circulation between the cold tank 2, the ice box 4 and the return water tank 3, which can prevent the water outlet of the cold tank 2 from freezing. In addition, this utility model uses the first refrigeration evaporator 21 and the second refrigeration evaporator 41 to prepare cold water at the same time, which can effectively improve the preparation efficiency of cold water and has the effects of high cold water preparation efficiency and effective prevention of ice formation in the cold tank.
