Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1-2 As shown, this embodiment provides an air cold source ice-making device, including a hollow ice-making bin 1, a plurality of ice-making cavities 2 are provided on the ice-making bin 1 and are vertically connected to each other from the top to the bottom, an internal ventilation mechanism and an internal heating mechanism are provided on the ice-making bin 1, and the internal ventilation mechanism and the internal heating mechanism surround the ice-making cavity 2 for ventilation and heating, the internal ventilation mechanism includes an air inlet 3 and an air outlet 4 located on the surface of the ice-making bin 1 and connected to the hollow inner cavity of the ice-making bin 1, a detachable sealing cover 16 is provided on the air inlet 3 and the air outlet 4, and a ventilation fan 5 is provided in the air inlet 3. The internal heating mechanism includes a water storage bin 6, a water inlet pipe 7 and a water outlet pipe 8 are respectively connected to the water storage bin 6, a valve 9 is provided on the water inlet pipe 7 and the water outlet pipe 8, the water outlet pipe 8 is also connected to a first water pump located inside the water storage bin 6, the other ends of the water inlet pipe 7 and the water outlet pipe 8 are both connected to the hollow inner cavity of the ice-making bin 1, a heating component is provided inside the water storage bin 6, and a water filling port 12 is provided on the water storage bin 6. The ice making bin 1 is suspended, and the suspension is realized by a plurality of support columns 15 at the bottom of the ice making bin 1. The support columns 15 are preferably 4 columns distributed at the four corners of the bottom of the ice making bin 1. The bottom of the ice making bin 1 is movably closed, and an ice receiving mechanism is provided below the ice making bin 1. The ice receiving mechanism includes a hydraulic platform 13 located below the ice making bin 1, and a plurality of telescopic rods are provided on the top of the hydraulic platform 13. The top of the telescopic rods is connected to an ice receiving platform 14, and the top surface of the ice receiving platform 14 is a movable sealing surface at the bottom of the ice making chamber 2.

[0024] When in use, the valves 9 on the water inlet pipe 7 and the water outlet pipe 8 are closed, and then the hydraulic platform 13 is started so that the bottom of the ice receiving platform 14 is close to the bottom of the ice making bin 1 and the bottom opening of the ice making chamber 2 is sealed. Then, each ice making chamber 2 is filled with water through an external water source, and then the ventilation fan 5 is turned on. The ventilation fan 5 allows cold air to flow into the hollow inner cavity of the ice making bin 1 through the air inlet 3 and flow around each ice making chamber 2, thereby quickly cooling the water in the ice making chamber 2 and solidifying it. The cold air then flows out of the hollow inner cavity of the ice making bin 1 from the air outlet 4. Then, the air inlet 3 and the air outlet 4 are sealed by the sealing cover 16, wherein the sealing connection between the sealing cover 16 and the air inlet 3 and the air outlet 4 can be bolted, snap-fit ​​or other methods, and the ventilation fan 5 is a waterproof structure. Fill the water storage tank 6 with water through the water inlet 12, and the heating component in the water storage tank 6 heats the water in the water storage tank 6, wherein the heating component can be electrically heated, and then open the valve 9, and the heated hot water flows into the hollow inner cavity of the ice making bin 1 through the water outlet pipe 8 driven by the water pump and flows back into the water storage tank 6 from the water inlet pipe 7, completing the heating of the surface of each ice making cavity 2. After heating, the part of the ice cube that is tightly attached to the surface of the ice making cavity 2 begins to melt and thus separates. At this time, start the hydraulic platform 13 again to make the ice cube receiving platform 14 descend to release the seal on the bottom opening of the ice making cavity 2, and the ice cube naturally slides from the ice making cavity 2 to the ice cube receiving platform 14, which is convenient for subsequent collection and transportation.

[0025] This embodiment cleverly utilizes the unique natural cold source in the north in winter, completely gets rid of the dependence on refrigerators, and through the unique ice-making bin design, is equipped with evenly arranged ice-making chambers connected at the top and bottom, and with the help of the natural circulation of natural cold air, efficient ice making is achieved. The entire process consumes very little electricity, and it operates at almost zero cost, solving the problem of power consumption and maintenance of the cold source. Moreover, as a natural ice-taking method, the present invention greatly reduces the requirements for water source restrictions compared to the ice-taking method on the frozen water surface, and pure water can be freely added to make edible ice. The ice-taking process saves labor and transportation costs, and the safety of the ice-taking process can also be effectively guaranteed.

[0026] Example 2

[0027] like Figure 1-2 As shown, the difference between this embodiment and embodiment 1 is that this embodiment further includes an automatic water injection mechanism, which includes a top surface of the ice making bin 1 with an outer concave surface, a plurality of water level sensors 10 are arranged on the top surface of the ice making bin 1, a water injection pipe 11 is arranged above the top surface of the ice making bin 1, and the other end of the water injection pipe 11 is connected to the second water pump inside the water storage bin 6; a water filling port 12 is arranged on the water storage bin 6. Other structures are the same as those in embodiment 1 and will not be repeated here.

[0028] When in use, after the bottom opening of the ice-making chamber 2 is sealed, water can be directly injected into the ice-making chamber 2 from the top of the ice-making chamber 1 through the water pump in the water storage tank 6 through the water injection pipe 11. Since the outer periphery of the top surface of the ice-making chamber 1 is concave, when the ice-making chamber 2 is filled with water, water will accumulate on the top of the ice-making chamber 1. When the water level rises to the position of the water level sensor 10, the control center stops the water supply by shutting off the second water pump in the water storage tank 6. Thereafter, the excess water on the top surface of the ice-making chamber 1 can be naturally melted and discharged during the heating and de-icing process.

[0029] In this embodiment, the bends of each pipeline are wrapped with thermal insulation material, which can protect the pipeline from freezing and cracking in extremely cold weather.

[0030] This embodiment can realize fully automatic unmanned operation. By installing a control center, the freezing time of ice can be controlled according to the ambient temperature to control the speed of the ventilation fan 5, the heating of the water storage tank 6 and the water pump switch, and the liquid level and time control when the ice is melted after freezing, the automatic drainage control when removing ice, the automatic descent of the sealing structure of the hydraulic platform 13 under the ice making bin 1, the automatic rise and seal control of the hydraulic platform 13 after removing ice, and the automatic water addition control of the ice making chamber 2 can be realized, and the ambient temperature, freezing time, water temperature changes during ice melting and the automatic calculation process can be realized. In addition, due to the high modularization, the maintenance of this embodiment is simple, and it can also be placed in a cold storage to make ice in summer, which is flexible and convenient.
