The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0030] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1-5 As shown, the ice-making machine provided by the embodiment of the present invention includes a body 1, a refrigeration assembly, a first ice-making assembly and a second ice-making assembly.

[0032] The machine body 1 is provided with a first door 2 and a second door 3 for opening or closing the machine body; a refrigeration assembly is provided in the machine body 1, and the refrigeration assembly includes a compressor 4, a condenser 5, a first evaporator 6, a second evaporator, a capillary tube and a valve which are connected to each other; a first ice-making assembly is provided in the machine body 1, and the first ice-making assembly includes an ice-making groove 7, a driving module 8, a first water pump, a water tank 9 and an ice storage bin 10, and the first door 2 is correspondingly provided outside the ice storage bin 10, and the driving module 8 is used to drive the ice-making groove 7 to rotate around the length direction of the ice-making groove 7. The ice storage bin 10 is located above the water tank 9, and the first water pump is used to transport water in the water tank 9 to the ice-making groove 7, and the ice-making groove 7 is used to prepare bullet-shaped ice and the first evaporator 6 is provided in the ice-making groove 7, and a baffle 11 is provided on the top of the ice-making groove 7, and the baffle 11 covers part of the ice-making groove 7 so that the two ends of the ice-making groove 7 form pouring ports 12 respectively, and the pouring ports 12 are located above the water tank 9 and exceed the two ends of the ice storage bin 10. The first evaporator 6 is disposed in the ice-making groove 7 to realize cooling of the ice-making groove 7, and is spaced apart from the inner wall of the ice-making groove 7 to prevent the ice-making groove 7 from colliding with the evaporator 6 during rotation.

[0033] The second ice-making component is arranged in the body 1, and the second ice-making component includes a transparent ice refrigerator 13, an auxiliary water tank 15, a second water pump and a heating component. The transparent ice refrigerator 13 is correspondingly arranged below the second door 3, the transparent ice refrigerator 13 and the auxiliary water tank 15 are connected, and an ice grid 17 is arranged in the transparent ice refrigerator 13. The second water pump is configured to circulate water in the transparent ice refrigerator 13 and the auxiliary water tank 15. The heating component surrounds and covers the side wall of the transparent ice refrigerator 13, and the second evaporator is arranged on the outside of the transparent ice refrigerator 13.

[0034] Among them, the first evaporator 6 is used to refrigerate the ice making tank 7 to prepare bullet ice, and the second evaporator is used to refrigerate the transparent ice making refrigerator 13 to prepare transparent ice. The compressor 4, condenser 5 and valve are respectively connected to the first evaporator and the second evaporator in a cycle, so that the first ice making component and the second ice making component can operate simultaneously.

[0035] When in use, the first water pump pumps water from the water tank 9 to the ice making trough 7 and the transparent ice making refrigerator 13, and the first evaporator 6 cools the ice making trough 7 so that the ice making trough 7 prepares opaque or translucent bullet ice, and the second evaporator cools the transparent ice making refrigerator 13 so that the transparent ice making refrigerator 13 can prepare transparent ice cubes.

[0036] In order to automatically remove the water in the ice making groove 7 and the bullet-shaped ice cubes in the ice making groove 7. The driving module 8 drives the ice making groove 7 to rotate, and pours the unfrozen water back to the water tank 9 through the pouring port 12. By introducing the high-temperature and high-pressure gas in the condenser 5 into the first evaporator 6, the first evaporator 6 heats and melts the ice cubes in the ice making groove 7, so that the ice cubes are no longer adhered to the first evaporator 6. After the ice making groove 7 is reversed, the ice cubes fall off under the action of gravity and enter the ice storage bin 10. It should be noted that since the pouring port 12 is located above the water tank 9 and exceeds the two ends of the ice making groove 7, it can ensure that the water is poured only from the pouring ports 12 on both sides as the ice making groove 7 rotates, avoiding the ice making groove 7, and flowing back to the water tank 9 from both sides, so as not to affect the quality of the ice cubes in the ice storage bin 10, and after the above steps of ice making are completed, it will automatically enter the next round of ice making.

[0037] Based on the above arrangement, the ice making efficiency is high, and bullet-shaped ice cubes and transparent ice cubes can be prepared.

[0038] In one embodiment, two infrared sensors 14 are provided in the body 1, and the two infrared sensors 14 are respectively used to detect the amount of ice cubes in the ice storage bin 10 and the installation position of the ice storage bin 10. When the amount of ice storage reaches the warning value, ice making is suspended until the ice cubes are taken out; when the ice storage bin 10 is not installed in place, the user is prompted to reinstall it in place; when the ice storage bin 10 is taken away, ice making is suspended.

[0039] In one embodiment, the ice maker further includes a control panel 20, which is mounted on the body 1 and is connected to the infrared sensor 14, the compressor 4, the valve, the drive module 8, the first water pump, the second water pump and the heating assembly. The control panel 20 is integrated with a processor capable of processing and analyzing information and generating control signals.

[0040] In one embodiment, one end of the water tank 9 extends out of the machine body 1, and the portion of the water tank 9 extending out of the machine body 1 is located below the first machine door 2. And the surface of the water tank 9 is flush with the surface of the first machine door 2 to maintain a regular shape.

[0041] In one embodiment, a water inlet 16 is provided at the bottom of the auxiliary water tank 15, a water outlet 18 is provided at the inner side of the second door 3, an input end of the second water pump is connected to the water inlet 16, an output end of the second water pump is connected to the water inlet 16, and the water inlet 16 is correspondingly arranged above the transparent ice refrigerator 13. When in use, the second water pump draws water from the auxiliary water tank 15 through the water inlet 16, and discharges it from the water outlet 18 of the second door 3, and the water at the water outlet 18 is discharged into the transparent ice refrigerator 13. Since the auxiliary water tank 15 is connected to the transparent ice refrigerator 13, the water circulation between the auxiliary water tank 15 and the transparent ice refrigerator 13 can be realized, so as to avoid the opacity of ice cubes due to the condensation of water too quickly. In addition, an overflow hole 19 is also provided on the inner wall of the transparent ice refrigerator 13, and the overflow hole 19 is used to limit the water level of the transparent ice refrigerator 13.

[0042] In one embodiment, when the second evaporator refrigerates the transparent ice refrigerator 13, the water inside the ice tray 17 condenses into ice cubes in a single direction, and the single direction can be one of the directions from bottom to top, from top to bottom, from left to right, and from right to left. And by driving the water body to keep moving in the transparent ice refrigerator 13 in the above manner, it can help the water body to discharge the gas dissolved in the water during the freezing process, making the ice body transparent. By controlling the refrigeration time of the second evaporator, the water in the auxiliary water tank 15 will not freeze, avoiding the ice from condensing and blocking the water inlet 16. It should be noted that the water flow rate of the water outlet 18 should be in an appropriate range, neither too slow, resulting in the water body not being truly circulated, affecting the transparency of ice making; nor too fast, resulting in bubbles during the injection process and condensing inside the ice cubes.

[0043] When the second ice-making component is working, the second water pump is in a continuous working state in the early stage of ice-making to form a water circulation; the water injection process of the water outlet 18 will bring in air, forming a low-pressure area at the water injection point, and the large bubbles generated by the air brought in by the water injection will quickly float to the water surface and be discharged, while the bubbles generated by the residual gas in the water are small, and some of them may be attached to the ice grid 17 and cannot be discharged. Therefore, in the later stage of ice-making, the flow rate of the water outlet 18 is adjusted accordingly to reduce the number of bubbles attached to the ice grid, so as to avoid the formation of pits on the outer surface of the transparent ice due to the presence of bubbles.

[0044] In one embodiment, the heating assembly can be a heating tube or a heating wire, and the transparent ice making refrigerator 13 is heated by the heating assembly, so that the ice cubes are easy to demould after being made, and the ice cubes are convenient to be taken out of the ice tray 17. In addition, it also includes a heat preservation layer, which is coated on the outer periphery of the heating assembly and is sealed and connected to the side wall of the transparent ice making refrigerator. The heat preservation layer can reduce the heat exchange, so that the cooling effect is good.

[0045] In one embodiment, the machine body 1 further comprises an observation window, which is installed on the first machine door 2 and is capable of observing the process of the first ice-making assembly preparing bullet-shaped ice cubes and the amount of ice produced.

[0046] The driving module 8 adopts a motor, the power output end of the motor is connected to one side of the ice-making groove 7, and the other side of the ice-making groove 7 is connected to a rotating shaft. The ice-making groove 7 is rotatably connected to the inner wall of the body 1 through the rotating shaft. Correspondingly, the corresponding position of the body 1 has a groove for installing the rotating shaft, so that the rotation process of the ice-making groove 7 is smooth.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
