[0026] See also Figure 1 The utility model provides an ice-making system capable of internal circulation, comprising an ice-making box 1 and a circulation pipeline. An ice maker 11 is arranged in the ice-making box 1. The water inlet end and the water outlet end of the circulation pipeline are both connected to the ice-making box 1. The circulation pipeline is used to extract the water in the ice-making box 1 from the water inlet end of the circulation pipeline, and return the water from the water outlet end of the circulation pipeline to the ice-making box 1. The water in the ice-making box 1 can be internally circulated through the circulation pipeline, and the bubbles and impurities in the ice-making process can be washed away by the internal circulation, so that the ice made is more transparent. The internal circulation of water can also make the water temperature in the ice-making box 1 uniform, so that the ice making is more uniform and the shape of the ice made is better.

[0027] Furthermore, the water inlet of the circulation pipeline is communicated with one side of the ice box 1, the water outlet of the circulation pipeline is communicated with the other side of the ice box 1, and the ice maker 11 is located between the water inlet of the circulation pipeline and the water outlet of the circulation pipeline. The connection points between the water inlet and the water outlet of the circulation pipeline and the ice box 1 are distributed on both sides of the ice box 1, which can improve the efficiency of the internal circulation.

[0028] Furthermore, the ice box 1 is provided with a first water inlet 12 and a second water inlet 13, which are distributed on the left and right sides of the ice maker 11, and the water inlet end of the circulation pipeline is connected to the first water inlet 12, and the water outlet end of the circulation pipeline is connected to the second water inlet 13. The circulation pipeline is connected to the ice box 1 by connecting the water inlet end of the circulation pipeline and the water outlet end of the circulation pipeline to the first water inlet 12 and the second water inlet 13 respectively.

[0029] Furthermore, the circulation pipeline includes a circulation pump 2 and a circulation pipe 3, one end of the circulation pipe 3 is connected to the first water port 12, the other end of the circulation pipe 3 is connected to the second water port 13, the circulation pump 2 is arranged on the circulation pipe 3, the water inlet end of the circulation pump 2 is connected to the first water port 12, and the water outlet end of the circulation pump 2 is connected to the second water port 13. In the ice making process of the ice making system of this scheme, the water in the ice making box 1 is circulated through the circulation pump 2 and the circulation pipe 3, and the bubbles and impurities in the ice making process are washed away by the water flow, so that the ice made is more transparent; and the water circulation can make the water temperature in the ice making box 1 uniform, the ice making is more uniform, and the ice shape is better.

[0030] Specifically, the first water inlet 12 and the second water inlet 13 are distributed on the left and right sides of the ice box 1. The circulating pump 2 can separate and discharge bubbles and impurities in the water flow. The circulating pump 2 can be a centrifugal pump. The impeller in the centrifugal pump can pump water after being soaked in water. The centrifugal pump has a longer life and lower noise.

[0031] Furthermore, the internal circulation ice making system comprises a cold water tank 4 and a water supply pipe 5, one end of the water supply pipe 5 is connected to the cold water tank 4, and the other end is connected to the ice making box 1. The water supply pipe 5 can supply water to the ice making box 1, so that there is sufficient water in the ice making box 1 for ice making.

[0032] Furthermore, a first branch port 31 is provided on the circulation pipeline 3 and is located after the circulation pump 2. One end of the water supply pipeline 5 is connected to the water outlet of the cold water tank 4, and the other end is connected to the first branch port 31. The circulation pipeline and the water supply pipeline 5 are designed in parallel, which simplifies the pipeline of the ice-making system, so that the ice-making system not only has multiple functions but also has a simple structure.

[0033] Specifically, the water replenishment pipeline 5 can guide the water in the cold water tank 4 to the ice box 1, so that the ice box 1 has enough water to make ice cubes. Specifically, the cold water tank 4 flows out from the water outlet of the cold water tank 4 and enters the water replenishment pipeline 5, and is divided at the first branch port 31, flows along the pipes on both sides of the first branch port 31 to the first water port 12 and the second water port 13, and then enters the ice box 1. When replenishing water, the ice box 1 can flush water to the circulation pump 2. It can be understood that when the circulation pump 2 is not working, it can still supply water to flow through.

[0034] Furthermore, the water replenishment pipeline 5 includes a water replenishment pipe 51 and a check valve 52. The check valve 52 is arranged on the water replenishment pipe 51. The check valve 52 is used to prevent the water in the circulation pipe 3 from flowing back to the cold water tank 4, so as to avoid that during the ice-making process, the water in the ice-making box 1 flows back to the cold water tank 4 due to internal circulation, resulting in too little water in the ice-making box 1, affecting ice-making of the ice-making system.

[0035] Furthermore, the water replenishment pipeline 5 also includes a water replenishment pump 53, which can increase the pressure of the water in the water replenishment pipeline 51 to make it flow to the ice-making box 1. The water replenishment pump 53 is arranged on the water replenishment pipeline 51 and is located before the check valve 52. The check valve 52 is arranged close to the first branch port 31, which can reduce the amount of water refluxed to the water replenishment pipeline 51 and reduce the water loss of the ice-making box 1 caused by the internal circulation.

[0036] Specifically, the pumping direction and the water replenishing direction of the circulation pump 2 are opposite. When the ice-making system is making ice, the circulation pump 2 is started. At this time, the first water inlet 12 is the water inlet of the circulation pipe 3, and the second water inlet 13 is the water outlet of the circulation pipe 3. The check valve 52 can prevent the circulating water from returning to the cold water tank 4, thereby realizing the internal circulation of the water in the ice-making box 1; and when the water replenishing pump 53 is turned on to replenish the ice-making box 1 with water, the water in the water replenishing pipeline 5 is diverted through the first branch port 31 to form two branches, one of which flows along the part of the circulation pipe 3 located after the first branch port 31 to the second water inlet 13, and the other branch flows back along the part of the circulation pipe 3 located before the first branch port 31 to the first water inlet 12, and fills the circulation pump 2 with water.

[0037] Furthermore, the internal circulation ice-making system comprises an ice storage chamber 6, and the ice storage chamber 6 is used to store ice cubes.

[0038] Furthermore, the ice storage chamber 6 is located at the bottom of the ice box 1, and the ice box 1 is provided with a flip driving mechanism (not shown in the figure) capable of driving the ice box 1 to flip. After the water in the ice box 1 is made into ice cubes by the ice maker 11, the ice box 1 is driven to flip by the flip driving mechanism, so that the ice cubes fall into the ice storage chamber 6 below the ice box 1 to store the ice cubes.

[0039] Furthermore, the ice-making system capable of internal circulation includes a first drainage pipe 7, the ice-making box 1 is provided with a first drainage port 14, the cold water tank 4 is provided with a first water inlet 41, one end of the first drainage pipe 7 is connected to the first drainage port 14, and the other end is connected to the first water inlet 41. After the water in the ice-making box 1 is made into ice, it needs to be heated and de-iced. In this process, part of the ice cubes will dissolve into water, and the water can flow back to the cold water tank 4 through the first drainage pipe 7 to avoid continuous contact between water and ice cubes and accelerate the dissolution of ice cubes in the ice-making box 1.

[0040] Furthermore, the ice-making system capable of internal circulation includes a second drainage pipe 8, the ice storage chamber 6 is provided with a second drainage port 61, the cold water tank 4 is provided with a second water inlet 42, one end of the second drainage pipe 8 is connected to the second drainage port 61, and the other end is connected to the second water inlet 42. The ice storage chamber 6 has a heat preservation function, but ice cubes are stored in the ice storage chamber 6 for a long time, and some ice cubes will still melt. The second drainage pipe 8 can lead the melted water back to the cold water tank 4 to avoid continuous contact between water and ice cubes and accelerate the melting of ice cubes in the ice storage chamber 6.

[0041] Furthermore, the cold water tank 4 is arranged at the bottom of the ice storage room 6, and the ice storage room 6 and the ice box 1 are both located above the cold water tank 4, which is conducive to the water in the first drainage pipe 7 and the second drainage pipe 8 to flow back to the cold water tank 4.

[0042] Furthermore, the ice maker 11 is provided with a plurality of ice columns 111, which can increase the heat exchange area between the ice maker 11 and water, and increase the heat exchange efficiency of the ice maker 11. During the ice making process, the temperature near the ice columns 111 is relatively low, and the solution in the ice box 1 is cooled between the ice columns 111 to form block-shaped ice cubes.

[0043] The ice-making system of the utility model can not only replenish water into the ice-making box 1, but also realize the water circulation in the ice-making box 1. The system is simple and efficient, which speeds up the water circulation of the ice-making box 1 during the ice-making process, takes away the bubbles and impurities precipitated during ice-making, effectively improves the transparency and uniformity of the ice cubes, and makes the ice cubes have a better texture.

[0044] In some other embodiments, an opening and closing device (not shown in the figure) is provided on the bottom wall of the ice box 1. When the ice box 1 finishes making ice, the opening and closing device can open the bottom of the ice box 1, so that the ice cubes in the ice box 1 can fall from the bottom of the ice box 1 into the ice storage chamber 6 under the action of gravity.

[0045] The above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit the protection scope of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, rather than all embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Although the utility model has been described in detail with reference to the above embodiments, ordinary technicians in this field can still combine, add, delete or make other adjustments to the features in the various embodiments of the utility model according to the circumstances without conflict, without making creative work, so as to obtain different other technical solutions that do not deviate from the concept of the utility model in essence, and these technical solutions also belong to the scope of protection of the utility model.
