A first casing through hole 1C is provided on the top of one side of the container recessed portion 1A, and the first casing through hole 1C is integrally injection-molded with the front casing 1. The cold water storage tank 4 is connected with a water replenishing device. 4A, the water inlet of the water replenishment device 4A is room temperature water; the water replenishment device 4A includes a first water inlet pipe 4A1 and a water inlet electric switch valve 4A2; the water inlet electric switch valve 4A2 is, for example, an electromagnetic valve, one end of the first water inlet pipe 4A1 is connected to the cold water storage tank 4 and communicates with the water cavity in the tank, and the other end is connected to the water outlet end connector of the water inlet electric switch valve 4A2, the water inlet end connector of the water inlet electric switch valve 4A2 is the water inlet source connection end, the water inlet electric switch valve 4A2 is connected to the controller 2 through an electric wire, and the controller 2 controls whether the water inlet electric switch valve 4A2 is opened to control whether the water source enters or not. After the water inlet electric switch valve 4A2 is opened, water is input into the cold water storage tank 4 through the first water inlet pipe 4A1 for water replenishment; after the water inlet electric switch valve 4A2 is closed, water cannot enter. Preferably: the water inlet end joint of the water inlet electric switch valve 4A2 is connected to an electric water inlet suction pump through a water pipe, the electric water inlet suction pump is connected to the controller 2 through an electric wire, and the electric water inlet suction pump is connected to a pure water filter through a water pipe.

The above-mentioned water replenishment device 4A is not limited to the above-mentioned electric automatic water replenishment and water addition, and the water replenishment device 4A can also be a non-electric automatic manual water adding device.

[0031] The refrigerant output end of the refrigeration compressor 3 is welded to one end of the refrigerant output pipeline 5, and the end of the refrigerant output pipeline 5 is welded to the refrigerant input end of the condensing ice particle making device 7, the tube hole diameter of the refrigerant output pipeline 5 is 3 mm to 6 mm, the refrigerant output recovery end of the condensing ice particle making device 7 is welded to one end of the refrigerant recovery pipeline 9, and the other end of the refrigerant recovery pipeline 9 is welded to the refrigerant recovery input end of the refrigeration compressor 3; the tube hole diameter of the refrigerant recovery pipeline 9 is 1 mm to 6 mm; the refrigerant output pipeline 5, the condensing ice particle making device 7, and the refrigerant recovery pipeline 9 are connected in series;

[0032] The branch of the refrigerant recovery pipeline 9 near the end of the refrigeration compressor 3 is welded to one end of the heat medium output pipeline 10, the diameter of the pipe hole of the heat medium output pipeline 10 is 3 mm to 6 mm, and the other end of the heat medium output pipeline 10 is welded to the refrigerant output recovery end of the condensing ice particle making device 7, and the refrigerant recovery pipeline 9, the heat medium output pipeline 10, and the condensing ice particle making device 7 are connected; the heat medium output pipeline 10 is sealed with a cold and hot medium flow regulating electric switch valve 11 through a screw assembly and a rubber sealing ring, that is: a valve hole is opened on the heat medium output pipeline 10, and a cold and hot medium flow regulating electric switch valve 11 is installed on the valve hole, and is sealed and connected to the heat medium output pipeline 10 through a screw assembly and a rubber sealing ring. The cold and hot medium flow regulating electric switch valve 11 controls the on / off of the heat medium output pipeline 10; in the refrigeration state, the cold and hot medium flow regulating electric switch valve 11 closes the heat medium output pipeline 10 to prevent the refrigerant from directly returning from the heat medium output pipeline 10. The refrigerant recovery pipeline 9 is relatively long, and the heat medium output pipeline 10 is relatively short, with a difference of more than 1 times. The diameter of the pipe hole of the refrigerant recovery pipeline 9 is smaller than the diameter of the pipe hole of the heat medium output pipeline 10.

[0033] The middle section of the refrigerant output pipeline 5 is immersed in the water cavity inside the cold water storage tank 4; a condensing ice particle making device 7 is arranged on one side inside the ice box 6, and an ice particle output electric device 8 is arranged on the other side; an ice particle outlet joint 601 at the front of the ice box 6 is arranged at the first housing through hole 1C, and the ice particle outlet joint 601 is butt-connected with the first housing through hole 1C and just fits, and an ice particle outlet joint 601 is provided with an ice particle outlet 602 connected to the inside of the ice box 6, and the ice particle outlet 602 is connected to the container recessed portion 1A;

[0034] An ice-making water pumping pipeline 12 is connected between the ice box 6 and the cold water storage tank 4, and a first water pump 13 is connected to the ice-making water pumping pipeline 12 to pump water from the cold water storage tank 4 to the condensing ice particle making device 7 to make ice;

[0035] An ice making residual water recovery pipeline 14 is connected between the bottom of the ice box 6 and the cold and cold water storage tank 4, and the residual water from ice making naturally flows back from the ice making residual water recovery pipeline 14 to the cold and cold water storage tank 4 for recycling.

[0036] When in use, first add a proper amount of water through the water replenishment device 4A, generally the amount of water is greater than 50% of the volume of the cold water reserve tank 4, generally 70% to 90% of the water tank capacity, and the water soaks the middle section of the refrigerant output pipeline 5; the controller 2 is energized in the forward direction to control the refrigeration compressor 3 to refrigerate, the cold and hot medium flow regulating electric switch valve 11 is in a closed state, the refrigeration compressor 3 refrigerates and generates a circulation flow of the refrigerant, the higher the working power of the refrigeration compressor 3, the colder the temperature of the refrigerant, on the contrary, the lower the working power of the refrigeration compressor 3, the lower the temperature of the refrigerant; the refrigerant is output from the refrigerant output pipeline 5, and when it flows to the middle section, it first generates heat exchange with the water in the cold water reserve tank 4. Due to the low temperature of the refrigerant and the relatively high water temperature in the box, the normal temperature water in the cold water reserve tank 4 is converted into cold water for storage and use, and the normal temperature water is also pre-cooled, and then the refrigerant flows through the condensation ice particle making device 7, and then is recovered from the refrigerant recovery pipeline 9 to the refrigeration compressor 3, and circulates;

[0037] When ice making is not required, the temperature of the refrigerant can be higher, so that the normal temperature water in the cold water storage tank 4 can be turned into cold water; when ice making is required, the temperature of the refrigerant is lower than 0°C, so that water can condense on the condensing ice particle device 7 to form ice particles;

[0038] When making ice, the controller 2 controls the first pumping pump 13 to pump water. The pumping time is generally 15 to 30 seconds. The reserved cold water in the cold water storage tank 4 is pumped to the bottom of the condensing ice particle making device 7 of the ice box 6. The ice column head 72 of the condensing ice particle making device 7 is immersed in the water. When the low-temperature refrigerant passes through the condensing ice particle making device 7, the ice column head 72 and the cold water exchange a hot and cold temperature difference, so that the cold water can be quickly cooled down and finally condensed at the ice column head 72 to form solid ice particles. The ice particle formation process takes about 20 seconds to 40 seconds, and the ice making time is determined by the refrigerant temperature and the ice making thickness factor. During the refrigerant circulation process, the water in the cold water storage tank 4 is pre-cooled in the first stage, and after cooling, it is pumped to the condensing ice particle device 7 for secondary cooling and condensation into ice. In this way, the time for the normal temperature water to slowly condense and ice-make in the ice column head 72 of the condensing ice particle device 7 can be reduced, and the ice making efficiency can be improved. After the ice is made, it is solidified on the ice column head 72.

[0039] The next step is to defrost: when ice is made, the controller 2 is reversely powered on to control the refrigeration compressor 3 to heat the heat medium. The heat medium heats up quickly, and the temperature of the heat medium is between 50°C and 80°C. The controller 2 controls the cold and hot medium flow regulating electric switch valve 11 to open, and the heat medium flows in the reverse direction, and is output from the reverse direction of the cold medium recovery pipeline 9, and then flows through the heat medium output pipeline 10, and then enters the condensation ice particle device 7. The heat medium flows in the reverse direction from the condensation ice particle device 7, and the heat medium and the ice condensed on the ice column head 72 instantly generate heat exchange, and the ice column head 72 heats up sharply, and the heat exchange temperature difference is at least 50°C. The inner layer of ice stuck to the column wall melts, and the ice particles fall off after a while, but not all of them melt. The whole de-icing process takes 5 to 15 seconds, and the falling time is determined by the heat exchange temperature, the thickness of the ice, and the sticky area. The diameter of the ice particles is 1.5 cm to 3 cm, and the height is 1.5 cm to 3 cm. The circulating heat medium time controls the time for the ice to just fall off, and the ice particles will not melt all of them immediately. The fallen ice is then output to the ice particle output electric device 8, and the controller 2 controls the ice particle output electric device 8 to work, and the ice particles are output to the ice particle outlet 602 and fall out, and the ice particles fall onto the container placement platform 1B. In the ice receiving container; the ice receiving container is for example: an ice receiving box, an ice receiving cup, an ice pot, etc.; the heat medium flows in the reverse direction from the condensing ice particle making device 7 and in the reverse direction from the refrigerant output pipeline 5. When it flows to the cold water storage tank 4, since the refrigerant output pipeline 5 is immersed in the cold water in the cold water storage tank 4, the heat medium and the cold water in the tank produce heat exchange. The temperature difference between the cold water and the heat medium is large, and the circulating heat medium also drops sharply, reducing the temperature of the heat medium in the circuit, which can be reduced by 30°C to 50°C, and then flows back to the refrigeration compressor 3, reducing the working pressure of the refrigeration compressor 3; the refrigeration compressor 3 is from preparing the heat medium, to circulation, The total time required to stop the preparation is less than 1 minute, generally 30 seconds to 50 seconds, which is short and will not affect the refrigeration compressor 3; after the refrigeration compressor 3 stops preparing the heat medium, the entire ice making process is completed; if it is necessary to make ice particles again, the above process is repeated; when defrosting, the cold water in the cold water reserve tank 4 is cleverly used to cool the circulating heat medium; when making ice particles, the role of the cold water reserve tank 4 is to pre-cool the water for use, and when defrosting, the pre-cooled cold water is used to cool the heat medium, killing two birds with one stone, reducing the complexity of the pre-cooling and heat medium cooling structure manufacturing.

[0040] Further preferred technical solution: a refrigeration device for making ice particles and cooling cold water also includes a refrigerant recovery and cooling device 15; the middle section of the refrigerant recovery pipeline 9 is connected to the refrigerant recovery and cooling device 15; because the refrigerant undergoes heat exchange with external water to make ice particles after the refrigerant is condensed in the ice particle making device 7, the external water absorbs cold energy to make ice, and the temperature of the refrigerant will become higher. After being cooled by the refrigerant recovery and cooling device 15, it flows back to the refrigeration compressor 3. The temperature of the recovered refrigerant flowing back to the refrigeration compressor 3 is lower, which can reduce the refrigeration working pressure of the refrigeration compressor 3, reduce the refrigeration power of the refrigeration compressor 3, and have higher refrigeration efficiency.

[0041] The refrigerant recovery and cooling device 15 is a water-cooled cooling evaporator 151, and the middle section of the refrigerant recovery pipeline 9 is immersed in the water cavity of the water-cooled cooling evaporator 151; the water-cooled cooling evaporator 151 is connected to a cold water inlet device 16 and a water outlet device 17;

[0042] During the ice-making process of the condensing ice particle making device 7, the low-temperature liquid refrigerant undergoes heat exchange with external water to make ice, and then absorbs the temperature of the external temperature difference water, so that the liquid refrigerant becomes a vapor refrigerant. When the water-cooled cooling evaporator 151 is working, cold water enters the water cavity of the water-cooled cooling evaporator 151 from the cold water inlet device 16, and heat is exchanged between the cold water and the middle section of the refrigerant recovery pipeline 9. The temperature of the cold water is low, and the temperature of the recovered vapor refrigerant is high. The heat dissipation removes the excess heat of the vapor refrigerant, cools the vapor refrigerant into a liquid refrigerant at normal temperature and pressure, and then flows back to the refrigeration compressor 3, so that the refrigeration working pressure of the refrigeration compressor 3 can be reduced, the refrigeration power of the refrigeration compressor 3 can be reduced, and the refrigeration efficiency is higher. The water temperature after exchanging with the vapor refrigerant becomes higher, and the water after the heat transfer is discharged from the water outlet device 17. This product uses water cooling to cool the vapor refrigerant into a liquid refrigerant.

[0043] The cold water inlet device 16 includes a cold water inlet pipe 161 and a cold water electric switch valve 162. One end of the cold water inlet pipe 161 is connected to the bottom of the water-cooled evaporator 151, and the other end of the cold water electric switch valve 162 is connected to the cold water electric switch valve 162. The cold water electric switch valve 162 is connected to the controller 2 through an electric wire. The controller 2 controls the on / off of the cold water electric switch valve 162. The cold water electric switch valve 162 can only enter cold water when it is opened, and cannot be closed. The water outlet device 17 is a residual water drainage pipe 171. The residual water drainage pipe One end of component 171 is connected to the top side wall of the water-cooled evaporator 151 and is connected to the inside of the water-cooled evaporator 151, and the other end is a free end; when the cold water electric switch valve 162 is opened, cold water enters the bottom of the water-cooled evaporator 151 from the cold water inlet pipe 161, and then flows upward to exchange heat with the gaseous refrigerant in the recycling circulation. The water temperature after the heat exchange becomes higher and cannot be reused. When the waste water is discharged, it finally flows out from the residual water drainage pipe 171; the residual water drainage pipe 171 is connected to the waste water drainage pipe to drain to the designated waste water discharge location for discharge.

[0044] Further preferred technical solution: the refrigerant recovery pipeline 9 includes a refrigerant recovery copper tube front section 91, a refrigerant recovery copper tube circuitous bending middle section 92, and a refrigerant recovery copper tube rear section 93. The copper tube has a good heat exchange effect, and the tube hole diameter of the refrigerant recovery copper tube front section 91 is more than half smaller than the tube hole diameter of the refrigerant recovery copper tube rear section 93; preferably: the tube hole diameter of the refrigerant recovery copper tube front section 91 is 15% to 30% of the tube hole diameter of the refrigerant recovery copper tube rear section 93; the tube hole diameter of the refrigerant recovery copper tube front section 91 is 1 mm to 2 mm; because the refrigerant is in the ice-making process of the condensing ice particle making device 7, after heat exchange, the liquid refrigerant becomes a vapor refrigerant, and the vapor refrigerant has a higher pressure and a faster circulation speed than the liquid refrigerant, so it is necessary to set a smaller tube hole diameter of the recovery pipe section. In the process of making ice particles, a large amount of cooling is required, and the refrigerant cannot circulate too fast and pass through smaller tube holes. The front section 91 of the refrigerant recovery copper tube with a small diameter is used to create congestion in the flow of the refrigerant, slow down the flow speed, and limit the flow. After the flow is limited, the flow rate becomes smaller, and the heat dissipation effect and the cooling effect of the heat exchange between the vapor refrigerant and the water-cooled evaporator 151 are good; at the same time, during the ice-making process of the condensing ice-making device 7, the refrigerant is recovered and limited by the front section 91 of the refrigerant recovery copper tube with a small diameter tube hole, and then the refrigerant enters the condensing ice-making device 7 and flows slowly, so that the condensing ice-making device 7 receives more cold water, the efficiency of ice-making is higher, the ice-making time is faster, and the ice-making effect is better: the front section 91 of the refrigerant recovery copper tube, the circuitous middle section 92 of the refrigerant recovery copper tube, and the rear section 93 of the refrigerant recovery copper tube are connected in sequence; the rear section 93 of the refrigerant recovery copper tube is welded and connected to the refrigerant recovery end of the refrigeration compressor 3; the rear section 93 of the refrigerant recovery copper tube is branched and connected to one end of the heat medium output pipeline 10;

The temperature of the cold water is generally selected to be 8°C to 15°C, generally around 10°C, which is more in line with the drinking temperature of the cool feeling. When not making ice, In the state of ice particles, the controller 2 controls the refrigeration compressor 3 to work, so that the refrigerant is output, and the refrigerant is heat-exchanged with the water in the cold water storage tank 4 through the refrigerant output pipeline 5 to produce cold water, or the cold water after making ice particles is used to process and make cold drinks such as iced milk tea and iced juice; or it can be directly drawn out for drinking; in this way, the cold water stored in the cold water storage tank 4 can not only be pre-cooled to make ice particles, but also can be drawn out to make cold drinks such as iced milk tea and iced juice by setting the ice water pumping pipeline 19, the second pumping pump 20, and the water outlet joint 18;

[0053] A condensing ice particle making device 7 is arranged above the ice making water tank 6C1. The condensing ice particle making device 7 is located in the first concave cavity 6A. The condensing ice particle making device 7 includes a U-shaped refrigerant circulation elbow 71 and a plurality of ice column heads 72. The diameter of the tube hole of the refrigerant circulation elbow 71 is 50% to 200% larger than the diameter of the tube hole of the refrigerant output pipeline 5. In this way, more refrigerant can be buffered and retained in the refrigerant circulation elbow 71, and more cold capacity can be obtained in the ice column heads 72 to improve the efficiency and effect of ice particle making. Generally, there are eight to sixteen ice column heads 72. The bottom of the refrigerant circulation elbow 71 extends downward to connect to a plurality of ice column heads 72. The interior of the ice column heads 72 is hollow and used for entering. The refrigerant is introduced into the ice making water tank 6C1, and a plurality of ice column heads 72 are inserted into the ice making water tank 6C1. The refrigerant circulation elbow 71 is located above the notch of the ice making water tank 6C1; the end of the refrigerant output pipeline 5 is welded to the refrigerant input end of the refrigerant circulation elbow 71, and the refrigerant output recovery end of the refrigerant circulation elbow 71 is welded to the refrigerant recovery pipeline 9; one end of the heat medium output pipeline 10 is welded to the rear section of the refrigerant recovery pipeline 9, and the other end of the heat medium output pipeline 10 is welded to the refrigerant output recovery end of the refrigerant circulation elbow 71; the end of the refrigerant output pipeline 5, the input end of the refrigerant recovery pipeline 9, and the end of the heat medium output pipeline 10 penetrate into the first concave cavity 6A from the rear wall of the box seat 61;

[0054] The ice particle output electric device 8 comprises a spiral ice particle output device 81 and a second motor 82. The second motor 82 is a small DC motor with a voltage of 5V to 10V. The second motor 82 is connected to the controller 2 through a wire. The front outer wall of the second concave cavity 6B of the box seat 61 is fixedly connected with the second motor 82 by screws. The second concave cavity 6B is provided with a spiral ice particle output device 81, and the front end of the spiral ice particle output device 81 is fixedly connected to the motor shaft of the second motor 82. The lower part of the front wall of the second concave cavity 6B of the box seat 61 extends to connect the ice particle output connector 601, and the ice particle output connector 601 is provided with an ice particle outlet 602 connected to the second concave cavity 6B. This is to further refine the specific structure of the ice particle output electric device 8, and the structure outputs ice particles smoothly without ice jam.

[0055] When ice particles are to be made, the controller 2 is energized in the forward direction to control the refrigeration compressor 3 to refrigerate, and the refrigerant flows into the refrigerant circulation elbow 71 through the refrigerant output pipeline 5, and then dispersed into each ice-making column head 72; the controller 2 controls the first pumping pump 13 to work and pump water from the cold water reserve tank 4, and the cold water enters the ice-making water tank 6C1 through the ice-making water pumping pipeline 12 and the ice-making water pumping water inlet 6D, and fills the ice-making water tank 6C1. The water in the ice-making water tank 6C1 will submerge the ice-making column head 72. If there is excess, it will overflow into the first concave cavity 6A, and return to the cold water reserve tank 4 for recycling through the first ice-making residual water recovery pipe 141; since the temperature of the refrigerant for ice making is low, generally -8°C to -15°C, the temperature difference between the inside and the outside is large, and the temperature difference occurs to generate heat exchange, and the water in contact with the ice-making column head 72 will quickly condense. The ice is frozen and fixed tightly, and the ice particle formation process takes about 20 seconds to 30 seconds; the time of the ice making process is controlled by the controller 2, and there is a certain distance between the ice column heads 72, and the ice particles will not stick together. The water in the ice making water tank 6C1 will not be completely frozen, but the water close to the ice column heads 72 will be condensed and frozen by the low temperature. After condensation and freezing, the controller 2 controls the motor shaft of the first motor 21 to rotate 80 degrees to 100 degrees in the positive direction, preferably about 90 degrees, to drive the water tank shell 6C to flip, and the ice plate 6C2 moves downward synchronously, and the notch flips over to pour out the unfrozen water in the water tank shell 6C. There is a gap between the water tank shell 6C and the first concave cavity 6A for water to flow, and the remaining water falls into the first concave cavity 6A, and then flows back to the cold water storage tank 4 through the first pipe 141 for recovering the remaining water from ice making;

[0056] When the ice particles are made, it is time to defrost. The controller 2 is synchronously reversely powered on to control the refrigeration compressor 3 to heat the heat medium. The heat medium heats up quickly and the temperature of the heat medium is between 50°C and 80°C. The controller 2 controls the cold and hot medium flow regulating electric switch valve 11 to open, and the heat medium flows in the reverse direction, flows from the reverse output of the cold medium recovery pipeline 9, and then flows through the heat medium output pipeline 10, and then reversely enters the cold medium flow elbow 71. The heat medium flows in the reverse direction from the cold medium flow elbow 71, and the heat medium and the ice condensed on the ice column head 72 instantly generate high-temperature heat exchange. The ice column head 72 heats up rapidly, and the heat exchange temperature differs by at least 50°C. The inner layer of ice stuck to the column wall melts, and the ice particles fall off in a short time. The whole defrosting process takes 5 to 15 seconds. The shedding time is determined by the exchange temperature, ice thickness, and sticky area. The diameter of the ice particles is between 1.5 cm and 3 cm, and the height is between 1. 5 cm to 3 cm, the heat medium is circulated for a time to control the time when the ice just falls off. The ice has a certain thickness and will not melt all at once. After the ice particles fall off, the controller 2 controls the motor shaft of the first motor 21 to reversely reset and rotate, driving the water tank shell 6C to reset and flip, and the ice-pushing plate 6C2 moves upward and resets synchronously, and the ice particles are picked up. When they are picked up to the low-position gap 6F, the ice particles automatically fall into the second concave cavity 6B through the low-position gap 6F. After the notch of the water tank shell 6C is horizontal upward, it is reset in place, the first motor 21 stops working, and the ice-pushing plate 6C2 is just placed on the edge of the low-position gap 6F; the controller 2 controls the second motor 82 to work and rotate, and the second motor 82 drives the spiral ice particle device 81 to rotate spirally, driving the ice particles to be output to the ice particle outlet 602 to fall out, and the ice particles fall into the ice receiving container placed on the container placement platform 1B, completing the ice particle making and ice particle taking;

[0057] During the de-icing process, the heat medium flows in the reverse direction from the refrigerant circulation elbow 71 and in the reverse direction from the refrigerant output pipeline 5. When the heat medium flows to the cold water storage tank 4, since the middle section of the refrigerant output pipeline 5 is immersed in the cold water in the cold water storage tank 4, the heat medium and the cold water in the tank generate heat exchange. The temperature difference between the cold water and the heat medium is large, and the circulating heat medium also cools down sharply, reducing the temperature of the heat medium in the circuit by 30°C to 50°C, and then flows back to the refrigeration compressor 3, reducing the working pressure / workload of the refrigeration compressor 3; the total time required for the refrigeration compressor 3 to prepare the heat medium, to circulate, to stop the preparation is less than 40 seconds, which is short and will not affect the refrigeration compressor 3.

[0058] Preferably: the ice particle outlet 602 is connected to an elastic reset sealing plate. When the ice particles are output, the ice particles use thrust or gravity to push open the elastic reset sealing plate. After the ice particles fall out, the elastic reset sealing plate automatically resets and closes the ice particle outlet 602 to prevent dust and crawlers from entering. The elastic reset sealing plate includes an elastic torsion spring and a reset sealing plate. The reset sealing plate is movably connected to the edge wall of the ice particle outlet 602 through a bracket. The edge wall of the ice particle outlet 602 and the reset sealing plate are connected by an elastic torsion spring. Under normal circumstances, the elastic torsion spring uses the reset elastic force to close the reset sealing plate and connect to the ice particle outlet 602.

[0059] Preferably: the ice particle outlet 602 is connected with a movable shaft, and the movable shaft is movably connected with a magnetic attraction reset sealing plate 22. A magnet 23 is fixed at the ice particle outlet 602. The magnetic attraction reset sealing plate 22 cooperates with the magnet 23 for magnetic attraction. When the ice particles are output, the ice particles use thrust or gravity to push open the magnetic attraction reset sealing plate 22. After the ice particles fall out, the magnetic attraction reset sealing plate 22 automatically resets and closes the ice particle outlet 602 through the magnetic attraction of the magnet 23 to prevent dust and reptiles from entering. Under normal circumstances, the magnetic attraction reset sealing plate 22 uses magnetic attraction to close the ice particle outlet 602.

[0062] When the ice particles are condensed, the controller 2 controls the motor shaft of the first motor 21 to rotate forward and drive the water tank shell 6C to flip, the travel switch contact 6C4 flips synchronously, the travel switch contact 6C4 leaves the starting travel switch 24, and the ice paddle 6C2 flips downward synchronously to flip the water tank shell 6C, and the notch of the ice making water tank 6C1 also flips downward synchronously to pour out the unfrozen water in the ice making water tank 6C1, and there is a gap between the water tank shell 6C and the first concave cavity 6A for water to flow, and the remaining water falls into the first concave cavity 6A, and then flows back to the cold water storage tank 4 through the first ice making residual water recovery pipe 141;

[0063] When the controller 2 controls the first motor 21 to work, the controller 2 also synchronously reverses the power supply to control the refrigeration compressor 3 to heat the heating medium and perform ice removal. The ice removal process is as described above.

[0064] The detached ice particles will fall to the position of the ice-pushing plate 6C2 in the first concave cavity 6A. When the travel switch contact 6C4 touches the reset return travel switch 25, the controller 2 controls the motor shaft of the first motor 21 to rotate in the opposite direction and drives the water tank shell 6C to reset and flip in the opposite direction. The travel switch contact 6C4 flips in the opposite direction synchronously, and the ice-pushing plate 6C2 moves upward in the opposite direction to pull up the ice particles. When the ice particles are pulled up to the low-position notch 6F, the ice particles automatically pass through the low-position notch 6F and fall into the second concave cavity 6B; after the notch of the water tank shell 6C is horizontally facing upward, the travel switch contact 6C4 touches the starting travel switch 24 again, and the controller 2 controls the first motor 21 and the refrigeration compressor 3 to stop working to reset in place. The ice-pushing plate 6C2 is just placed at the edge of the low-position notch 6F, which is an ice-making process.

[0065] Further preferred technical solution: the first concave cavity 6A is tilted toward one end, and a first water return hole 6A1 is opened at the lower end. The first water return hole 6A1 at the bottom of the first concave cavity 6A and the cold water storage tank 4 are tightly connected with a first pipe 141 for recovering residual water from ice making. The first concave cavity 6A, the first water return hole 6A1, the first pipe 141 for recovering residual water from ice making, and the cold water storage tank 4 are connected.
