[0044] Reference Figure 2 The first connecting plate 232 is provided with a first sealing ring 233 around the circumference of the upper hemispherical shell mold 231; the second connecting plate 242 is provided with a second sealing ring 243 around the circumference of the lower hemispherical shell mold 241, and when the upper hemispherical shell mold 231 and the lower hemispherical shell mold 241 are fitted, the first sealing ring 233 can be embedded in the second sealing ring 243, and in order to ensure that the first sealing ring 233 can be embedded in the second sealing ring 243, the outer diameter of the first sealing ring 233 should be smaller than the inner diameter of the second sealing ring 243. Please refer to Figure 5 , Figure 5 is another sealing design profile view of the upper and lower hemispherical shell molds of the utility model. The edge of the upper hemispherical shell mold 1 protrudes from the first connecting plate 232, and the edge of the upper hemispherical shell mold 1 is provided with a groove 234, and the groove 234 is provided with a third sealing ring 235, and the edge of the lower hemispherical shell mold 1 is recessed in the second connecting plate 242, and when the upper hemispherical shell mold 1 and the lower hemispherical shell mold 1 are fitted, the third sealing ring 235 is arranged between the edge of the upper hemispherical shell mold 1 and the edge of the lower hemispherical shell mold 1. By increasing the sealing ring, the sealing property between the upper hemispherical shell mold 231 and the lower hemispherical shell mold 1 is improved, heat transfer is reduced, and ice ball rapid molding is also promoted.

[0045] The upper half-spherical shell mold 231 and the lower half-spherical shell mold 241 can be made of copper or stainless steel, or can be made of aluminum or copper alloy or aluminum alloy. The selection of the above materials can make the mold have good corrosion resistance and heat conductivity. The inner walls of the upper half-spherical shell mold 231 and the lower half-spherical shell mold 241 are sequentially provided with a nano-aluminum oxide coating and a graphene coating. Spraying the above coatings on the inner walls of the molds can further improve the heat exchange efficiency and speed up the ice ball forming time. The lower half-spherical shell mold 241 includes a lower half-spherical inner shell mold 2411, a lower half-spherical intermediate shell mold 2412, and a lower half-spherical outer shell mold 2413.

The second closed interlayer space is formed between the lower half-spherical outer shell mold 2413 and the lower half-spherical intermediate shell mold 2412, and the second closed interlayer space is filled with a heat preservation material such as heat preservation cotton. Filling the heat preservation material can reduce the entry of external heat into the mold and prevent the loss of cold energy inside the mold, thereby improving the refrigeration efficiency and speeding up the freezing speed.

[0046] Referring back to Figure 1 and Figure 2 The ice supporting device 3 is arranged below the ice forming device 2 and includes a buffer plate 31, an ice supporting plate 32, and an ice storage basket 33. The buffer plate 31 is arranged perpendicularly to the second fixed plate 24 and is connected to one side of the second fixed plate 24 through a spring hinge 311. The ice supporting plate 32 is arranged below the buffer plate 31 and the lower half-spherical shell mold 241 and is detachably connected to the inner walls of the shell 1 on both sides. The ice storage basket 33 is arranged obliquely below the ice supporting plate 32, and the bottom of the ice storage basket 33 is provided with a water leakage mesh. When the ice ball with regular shape is formed by the ice forming device 2, the ice ball falls from the upper half-spherical shell mold 231 and rolls along the buffer plate 31 to the ice supporting plate 32, and finally rolls into the ice storage basket 33 for temporary storage. The arrangement of the buffer plate 31 can significantly reduce the impact force generated when the ice ball rolls down, avoid damage to the appearance of the ice ball due to excessive impact force, and also reduce the direct impact of the ice ball on the ice supporting plate 32 or the ice storage basket 33, thereby prolonging the service life of the equipment. The buffer plate 31, the ice supporting plate 32, and the ice storage basket 33 are all provided with a buffer pad made of rubber. When the ice ball falls from the lower half-spherical shell mold 241 to the buffer plate 31 and the ice supporting plate 32, the buffer pad can effectively absorb the impact force, reduce the vibration transmission to other parts of the equipment, enhance the stability of the equipment operation, and also reduce the risk of ice ball breakage when falling.

[0047] Referring back to Figure 1 and Figure 2The water supply device 4 comprises a water tank 41, a water pump 42 and a water pipe 43. The water tank 41 is arranged below the ice storage basket 33 so that the water in the ice storage basket 33 can be discharged into the water tank 41 in time. One side of the water tank 41 is connected with the water inlet end of the water pump 42. The water outlet end of the water pump 42 is connected with the water pipe 43. The water outlet end of the water pipe 43 is arranged opposite to the water injection port 2311 of the upper hemispherical shell mold 231. Of course, the water pipe 43 is preferably a hose. In this way, the hose can be closer to the water injection port 2311 of the upper hemispherical shell mold 231 during water injection, so as to ensure that the water flow can be quickly and accurately injected into the mold, thereby reducing the water injection time and improving the ice making efficiency. In addition, the hose can also be used to flexibly adjust the water injection angle, so as to ensure that the water can be quickly and uniformly injected under different ice making conditions, thereby preparing ice balls with regular shapes. The water inlet end of the water pump 42 is provided with a filter. The filter comprises a non-woven cotton filter layer, an activated carbon filter layer and an ultrafiltration membrane filter layer arranged in sequence. The ice balls made of the water purified by the filter can effectively improve the transparency and purity of the ice balls, thereby improving the quality of the ice balls. The water pipe 43 is provided with a flow sensor and an electromagnetic valve. The flow sensor and the electromagnetic valve are electrically connected with the control device 6. The control device 6 can automatically control the flow and time of water supply according to the forming requirements of the ice balls and the temperature of the mold. For example, the water supply flow can be appropriately increased in the early stage of ice ball forming, so as to accelerate the freezing speed of the ice balls. In the later stage of ice ball forming, the water supply flow can be reduced, so as to avoid the formation of thick ice layer on the surface of the ice balls. At the same time, the water supply temperature can be adjusted in real time according to the temperature change of the mold, so as to ensure the forming quality of the ice balls.

[0048] The water supply device 4 is provided with a pre-cooling coil pipe. The pre-cooling coil pipe is connected with the pipeline 53 of the refrigeration device 5. The pre-cooling coil pipe can utilize the cold energy generated by the refrigeration device to pre-cool the water to be made into ice in the water supply device 4, so that the temperature of the water can be reduced to close to the freezing point before the water enters the ice making device 2. In this way, the time required for the water to freeze in the ice making device 2 can be reduced, so as to accelerate the ice making speed and shorten the ice ball forming time.

[0049] Referring back to Figure 2The refrigeration device 5 comprises a compressor 51, a condenser 52, a pipeline 53, a defrosting valve 54 and a fan 55. The pipeline 53 is communicated with the pre-cooling coil, and the refrigerant flows in the pipeline 53. The defrosting valve 54 is arranged on the pipeline 53. In the embodiment, the defrosting valve 54 is specifically selected as an electromagnetic valve. The fan 55 is arranged on one side of the condenser 52. The refrigerant outlet of the compressor 51 is communicated with the refrigerant inlet of the condenser 52 through the pipeline 53. The refrigerant outlet of the condenser 52 is communicated with the first closed interlayer space through the pipeline 53. The first closed interlayer space is communicated with the refrigerant inlet of the compressor 51 through the pipeline 53. The compressor 51 compresses the refrigerant gas into a high-temperature and high-pressure state. The compressed refrigerant gas enters the condenser 52 through the pipeline 53. The condenser 52 cools and liquefies the high-temperature and high-pressure refrigerant gas discharged by the compressor 51, and releases the heat absorbed by the refrigerant in the compression process to the surrounding environment. The fan 55 accelerates the flow of air around the condenser 52 by forced convection, thereby improving the heat dissipation efficiency of the condenser 52. The defrosting valve is in a closed state in the normal refrigeration process. When defrosting is needed, the defrosting valve is opened, and the refrigerant directly enters the first closed interlayer space through the defrosting valve, thereby melting the frost layer by using the heat of the high-temperature and high-pressure liquid refrigerant, and effectively solving the problem of frost formation on the surface of the lower half-spherical shell mold 241. The first closed interlayer space is a place where the refrigerant exchanges heat with the lower half-spherical shell mold 241. The heat in the upper half-spherical shell mold 231 and the lower half-spherical shell mold 241 is taken away by the evaporation of the refrigerant in the first closed interlayer space, thereby realizing the freezing of the ice ball.

[0050] Referring back to Figure 1 The shell 1 is provided with a plurality of height-adjustable supporting legs 11. The supporting legs 11 are made of stainless steel, and the bottom of each supporting leg 11 is provided with an anti-skid rubber pad. By adjusting the height of the supporting legs, the ice maker can be kept stable and horizontal on different placement surfaces, thereby avoiding shaking of the equipment during operation due to unstable placement, and affecting the ice making effect and the service life of the equipment.

[0051] In use, first check whether the defrosting valve 54 is in the closed state, if yes, the normal start water supply device 4, water pump 42 from the water tank 41, water first through the water pump 42 inlet filter, in turn through the non-woven cotton filter layer, activated carbon filter layer and ultrafiltration membrane filter layer purification, into the pre-cooling coil of water supply device 4, at this time the refrigeration device 5 of cold through the pipeline 53 to the pre-cooling coil, the temperature of the water to near freezing point, for subsequent ice making ready. Then the control device 6 control driving element 211 start, through the synchronous belt 214 transmission, so that the moving plate 23 along the support column 22 down, until the upper half spherical shell mold 231 and the lower half spherical shell mold 241 closely, at this time the first sealing ring 233 embedded in the second sealing ring 243, form a good seal. Control device 6 according to the set parameters, open the solenoid valve on the water pipe 43, at the same time control the speed of the water pump 42, so that the purified and pre-cooled water through the water pipe 43 from the water inlet 2311 of the upper half spherical shell mold 1 mold into the mold, the injection process flow sensor real-time monitoring of water injection, when the set injection amount, solenoid valve is closed, stop injection.

[0052] After the completion of the injection, the refrigeration device 5 starts to work. Compressor 51 will be compressed into a high temperature and high pressure state of refrigerant gas, compressed refrigerant gas through the pipeline 53 into the condenser 52, condenser 52 will be cooled and liquefied high temperature and high pressure refrigerant gas, while releasing heat, fan 55 by forced convection to accelerate the flow of air around the condenser 52, improve the heat dissipation efficiency. Liquid refrigerant through the pipeline 53 into the first closed space, here the refrigerant evaporates heat, the upper half spherical shell mold 231 and the lower half spherical shell mold 241 inside the heat away, so that the water in the mold is rapidly cooled and gradually frozen into ice ball. In the whole process of refrigeration, control device 6 according to the temperature change of the mold real-time adjustment of water temperature and refrigeration device 5 operation parameters, ensure the uniform freezing and forming quality of ice ball.

[0053] When the ice ball is shaped, the control device 6 first opens the defrosting valve 54, and then controls the driving member 211 to start working, and the moving plate 23 is moved upward along the support column 22 under the action of the driving member 211, the upper hemispherical shell mold 231 is separated from the lower hemispherical shell mold 241, and the ice ball is separated from the upper hemispherical shell mold 231 under the action of gravity. The ice ball first falls on the buffer plate 31, and the rubber buffer pad on the buffer plate 31 effectively absorbs the impact force generated when the ice ball rolls down, so as to avoid damage to the appearance of the ice ball. The ice ball rolls down to the ice holding plate 32 along the buffer plate 31, and the rubber buffer pad on the ice holding plate 32 continues to play a buffering role, reducing the impact of the ice ball on the ice holding plate 32. Finally, the ice ball rolls into the ice storage basket 33 for temporary storage, and the water leakage mesh at the bottom of the ice storage basket 33 can drain the water after the ice ball melts to the water tank 41, realizing the recycling of water resources. After completing the ice making process, the control device 6 controls the action of each part according to the set program, and repeats the above steps to carry out the next ice making. When the mold is damaged or needs to be cleaned and maintained, the first connecting plate 232 and the first fixed plate 21 and the second connecting plate 242 and the second fixed plate 24 can be conveniently disassembled, and the upper hemispherical shell mold 231 and the lower hemispherical shell mold 241 are taken out for processing, so as to reduce the downtime and improve the ice making efficiency.

[0054] The above is only an embodiment of the present application and is not used to limit the present application. The present application can be variously changed and modified for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made in the spirit and principle of the present application shall be included in the scope of the claims of the present application.
