5 plays an important role in the process, specifically, the ice cubes are demolded by the water injection method, in the process, the ice cubes and water will mix and fall, because the temperature of the water is higher than that of the ice cubes, the ice cubes will spontaneously absorb the heat of the water, causing the ice cubes to melt, affecting the shape of the ice cubes, and if the ice cubes are not taken out immediately after falling into the ice storage basket, the subsequent falling water will continue to pour on the surface of the ice cubes, causing the ice cubes to melt quickly until they are completely melted, resulting in a decrease in the efficiency of making ice cubes, the ice-water separation mechanism 5 can quickly separate the ice cubes from the water, reducing the contact time of the ice cubes and the water, specifically, the ice-water separation mechanism 5 includes a separation disc 7, a water guide disc 8 and an ice storage basket, the separation disc 7 first contacts the ice cubes and water, the bottom plate of the separation disc 7 is inclined to facilitate the flow of ice cubes, and the bottom plate of the separation disc 7 is provided with a plurality of drain holes 15, the ice cubes cannot pass through the drain holes 15, therefore, the ice cubes slide down the inclined bottom plate and fall into the ice storage basket, and the water is separated

[0040] Example three:

[0041] As shown in Figures 1-13, the center of gravity distribution and the layout of the device are optimized. The refrigeration device mainly includes core components such as compressor, radiator and refrigerant bottle, etc. These components are relatively heavy, so they are installed at the bottom of the rack 1, which can effectively reduce the center of gravity of the whole device, help prevent the ice maker from tipping over during operation or handling, and improve its safety and reliability. Above the refrigeration device, a waterproof box is installed. The waterproof box is one of the key improvements of the invention, which aims to solve the problem of water overflow during ice making and ensure that the internal circuit and metal structure are not damaged by water. During the ice making process, water in the mold will overflow and splash everywhere. This not only wastes water resources, but also easily damages the internal circuit, causing the performance of the electrical appliance to decline, and even causing a short circuit. In addition, the long-term contact of the overflowing water with the metal structure is easy to cause corrosion, which shortens the service life of the device. Therefore, by installing the ice making components inside the waterproof box, the splashing water can be effectively limited to flow only in the waterproof box, thereby protecting the core components of the ice maker. The bottom of the waterproof box is provided with a water storage tank 4, which is mainly used to collect the overflowing water during ice making, and can further recycle these water resources. This design not only protects the environment, but also significantly saves water resources and improves the economic benefits of the device. In addition, the waterproof box is also fixedly installed with ice-water separation mechanism 5 and ice making device 6, which play a crucial role in the ice making and ice unloading process. Specifically, the ice making device 6 is responsible for converting water into ice cubes. The ice making device 6 is connected to the evaporative plate 11 of the refrigeration device through the copper pipe 14, thereby completing the overall ice making process. After the ice making is completed, the ice cubes need to be demolded from the mold. At this time, water is needed to complete the ice cube demolding process. The specific steps are to inject water into the ice making device 6 to melt the connection surface between the ice cubes and the mold, thereby easily demolding. However, the problem during this process is that the ice cubes and water will mix and fall down. Since the water temperature is higher than the ice cube temperature, the ice cubes will absorb the heat of the water and partially melt, affecting the shape and quality of the ice cubes. In addition, if the ice cubes are not taken out in time after falling into the ice storage basket, the subsequent falling water will continue to pour on the surface of the ice cubes, further accelerating the melting of the ice cubes and reducing the ice making efficiency. In order to solve this problem, the invention installs the ice-water separation mechanism 5 below the ice making device 6. The ice-water separation mechanism 5 includes a separation disc 7, a water guide disc 8 and an ice storage basket. When the ice cubes and water fall off from the ice making device 6, they first contact the separation disc 7. The bottom plate of the separation disc 7 is designed to be inclined, which is more conducive to the sliding of the ice cubes. The bottom plate is covered with a plurality of drainage holes 15, the size of which is smaller than that of the ice cubes. The ice cubes cannot pass through but the water can, so the ice cubes slide into the ice storage basket along the bottom plate, while the water is separated from the ice cubes by the drainage holes 15 and drips onto the water guide disc 8, thereby avoiding the water from contacting the ice cubes in the ice storage basket again and preventing the ice cubes from melting. The composition of the ice making device 6 includes ice making lower mold 10, evaporative plate 11 and water spraying pipe 12.The first mold 19 is installed in the ice making lower mold 10, and cooperates with the second mold 23 on the evaporating plate 11 to form a complete ice making mold. In structure, the water storage tank 4 is connected to the water spraying pipe 12 through the water guide pipe 13, and water is extracted from the water storage tank 4 by the electric pump and delivered to the water spraying pipe 12, and the water spraying pipe 12 provides water required in the ice making and demolding processes. The water circulation system improves the utilization rate of water resources. The important components of the ice making lower mold 10 include the first mold 19, the water injection chamber 20, and the cold water tank 21. The first mold 19 is installed in the water injection chamber 20, and when demolding, the first mold 19 is soaked in water by adding water to the water injection chamber 20, so that the ice ball is loosened from the first mold 19. Then, the demolding motor is started to drive the ice making lower mold 10 to overturn downward, so that the ice making device 6 is opened, and at this time, the ice ball is still fixed on the second mold 23 of the evaporating plate 11. At this time, the directional valve 36 in the refrigeration equipment switches the direction, so that the evaporating plate 11 is switched from the refrigeration function to the heating function. Specifically, the directional valve 36 switches the relevant path of the refrigeration equipment from the radiator corresponding to the refrigeration function to the evaporating plate 11, so that the evaporating plate 11 is rapidly heated, so that the ice ball is quickly separated from the second mold 23, and the whole demolding process is completed.

[0042] The separation disc 7 of the present application is provided with a drain hole 15 and an ice outlet 16, the water guide disc 8 is provided with a drain outlet 17, and the ice storage basket is provided with a water passing hole 18. The bottom plate of the separation disc 7 is provided with a drain hole 15 and an ice outlet 16. The function of the drain hole 15 is to quickly drain the water mixed with the ice, so that the ice can quickly separate from the erosion of water. The size of the drain hole 15 is smaller than the size of the ice, which ensures that the water can be quickly drained, and ensures that the ice will not fall through the drain hole 15. The ice can smoothly slide down the inclined bottom plate of the separation disc 7, fall into the ice storage basket through the ice outlet 16, and thus complete the separation of ice and water. The inclined design of the bottom plate of the separation disc 7 is to accelerate the sliding of the ice forward by gravity, so that the ice separation process is more smooth and fast. Secondly, the water guide disc 8 is located at the bottom of the separation disc 7 and covers all the drain holes 15 below, and its main function is to collect the water dripping from the drain holes 15. The water guide disc 8 is provided with a drain outlet 17, through which the collected water can be smoothly drained from the water guide disc 8 and can be drained into the water storage tank 4 again, realizing water recycling. This design not only prevents water from flowing back to the ice storage basket and avoiding the contact with the ice again, but also effectively manages and utilizes water resources, and improves the environmental performance of the ice maker. The ice storage basket is provided with a water passing hole 18, which is designed in cooperation with the drain outlet 17 of the water guide disc 8. Since the water guide disc 8 is located above the ice storage basket, the water passing hole 18 is needed to make the water drained from the drain outlet 17 of the water guide disc 8 fall into the water storage tank 4 through the water passing hole 18. After demolding, the ice first falls onto the separation disc 7, and the inclined bottom plate of the separation disc 7 and the ice outlet 16 design make the ice quickly slide into the ice storage basket, and at the same time, the water mixed together is quickly drained through the multiple drain holes 15. The water falls into the water guide disc 8 through the drain holes 15, and then is drained or recycled through the drain outlet 17, ensuring that the water will not contact the ice again. Finally, the water passing hole 18 provided with the ice storage basket ensures that the inside of the ice storage basket remains dry and clean, preventing the ice from melting during storage. This series of designs not only improves the ice making efficiency and ice quality of the automatic ice maker, but also effectively solves many problems faced by traditional ice makers in the ice-water separation process.

[0043] The water guide disc 8 of the present application is located below the drain hole 15, the ice storage basket is located below the ice outlet 16, and the water overflow port 18 is located below the drain port 17. The structural design further optimizes the path of water flow and ice flow, making the entire ice making and ice removal process more smooth and efficient. Considering the position of the water guide disc 8, the water guide disc 8 is accurately located below the drain hole 15 on the separation disc 7. Such design ensures that when the ice block is demolded and slides to the separation disc 7, the excess water can be immediately drained through the drain hole 15 and caught by the water guide disc 8. The water guide disc 8 not only can effectively collect the water drained through the drain hole 15, but also can prevent the water from pouring on the ice storage basket and prevent the ice block from being melted. The water guide disc 8 is provided with a drain port 17, which not only facilitates the rapid drainage of water, but also realizes the recycling and recycling of water. The drained water can flow back to the water storage tank 4 through a reasonably designed pipeline system for the next ice making cycle, greatly improving the use efficiency of water resources and following the concept of environmental protection and sustainable development. The bottom of the ice storage basket is provided with a water overflow port 18, which is located just below the drain port 17 of the water guide disc 8. Even if there is residual moisture through the ice storage basket, the water can also flow out smoothly through the water overflow port 18. This design detail ensures a dry environment inside the ice storage basket, thereby prolonging the shelf life of the ice block and preventing it from melting or sticking due to moisture interference during storage. The position cooperation of the water overflow port 18 and the drain port 17 makes any excess moisture generated during ice making flow into the water storage tank 4 quickly, without pouring into the ice storage basket, which affects the shape and quality of the ice block. Overall, the present application optimizes the positional relationship of each component, with the water guide disc 8 located below the drain hole 15, the ice storage basket located below the ice outlet 16, and the water overflow port 18 located below the drain port 17, making the water flow and ice block flow path more reasonable and efficient. This design not only improves the overall ice making efficiency, but also guarantees the quality and storage conditions of the finished ice block, reducing water resource waste.

[0044] The ice-making lower mold 10 of the present application includes a first mold 19, a water injection chamber 20, and a cold water tank 21, wherein the first mold 19 is fixedly installed inside the water injection chamber 20, and the cold water tank 21 is fixedly installed at the bottom of the water injection chamber 20. This design significantly improves the efficiency of the ice-making process and the quality of the ice cubes. The first mold 19 cooperates with the second mold 23 on the evaporative plate 11 of the ice-making device 6 to form a complete ice-making mold. The water injection chamber 20 plays a key role in the ice-making process, not only as a structure to fix the first mold 19, but also by adding water to soak the first mold 19 during demolding, so that the ice cubes quickly separate from the first mold 19, greatly improving the demolding efficiency and ensuring the shape and quality of the ice cubes. In addition, the cold water tank 21 is set at the bottom of the water injection chamber 20 as a crucial buffer zone in the water circulation system. Water is pumped from the cold water tank 21 to the sprinkler pipe 12, but during ice-making, the water in the sprinkler pipe 12 cannot quickly fill the entire ice-making mold, so an additional electric pump is needed to inject water into the ice-making mold. By installing a mold water injection pump 22 at the bottom of the cold water tank 21, cooling water can be efficiently and accurately injected into the first mold 19, thereby improving the quality of the ice cubes and the efficiency of ice-making. The cold water tank 21 is fixedly installed with the mold water injection pump 22, and the output end of the mold water injection pump 22 is connected to the first mold 19. The mold water injection pump 22 is a key component in the entire water circulation system, and its main function is to quickly pump water from the cold water tank 21 and inject it into the ice-making mold. Specifically, the output end of the mold water injection pump 22 is directly connected to the first mold 19, ensuring that the cooling water can quickly and efficiently enter the mold. Through a pre-set control program and sensors, the mold water injection pump 22 can automatically start and stop as needed, adjusting the water quantity and injection speed. This intelligent water injection process not only simplifies user operation, but also significantly improves the stability of the equipment operation and the efficiency of ice-making. The entire water injection process is carried out in a precisely controlled system, ensuring the stability of the quality of the ice cubes.

[0045] The bottom of the evaporation plate 11 is provided with a second mold 23, and the top of the evaporation plate 11 is fixedly installed with an evaporation pipe 24. This design improves the efficiency and stability of the ice making process, making the entire ice making process more reliable and intelligent. The evaporation plate 11 plays a core cooling role in the ice maker, and is one of the key components of the entire ice making process. The bottom of the evaporation plate 11 is provided with a second mold 23, which can make the evaporation plate 11 directly contact with the mold, more effectively transfer heat, and improve the ice making efficiency. The second mold 23 is used in cooperation with the first mold 19 to form a complete ice making mold system, which improves the ice making efficiency and the ice block demolding efficiency. Specifically, the ice making lower mold 10 includes the first mold 19, the water injection bin 20, and the cold water tank 21. The first mold 19 is installed in the water injection bin 20. When demolding, water is added to the water injection bin 20 to soak the first mold 19, so that the ice ball is separated from the first mold 19. The demolding motor drives the ice making lower mold 10 to flip down, so that the ice making device 6 is opened. At this time, the ice ball is still fixed on the second mold 23 of the evaporation plate 11. At this time, the directional valve 36 of the refrigeration equipment switches the direction, and the evaporation plate 11 generates heat. Specifically, the directional valve 36 switches the function of the evaporation plate 11 and the radiator of the refrigeration equipment, so that the ice ball is quickly separated from the second mold 23, and the entire demolding process is completed. The top of the evaporation plate 11 is fixedly installed with the evaporation pipe 24. The evaporation pipe 24 is designed to optimize the cooling effect. The evaporation pipe 24 is connected with the refrigerant. In the ice making process, the evaporation pipe 24 absorbs the heat in the system through the evaporation of the refrigerant, so as to realize the cooling of water in the ice making process. The high-efficiency cooling characteristics of the evaporation pipe 24 can make the ice making process more rapid and effective, reduce the time of each ice making cycle, and improve the overall ice making efficiency of the equipment.

[0046] The ice making device 6 is fixedly installed on the waterproof box through the fixing frame 26, the fixing frame 26 is fixedly installed with the mold closing motor 27, and one side of the ice making lower mold 10 is rotationally connected with the fixing frame 26. The design not only improves the overall stability and operation efficiency of the ice maker, but also provides an efficient and intelligent ice making and demolding system. The design purpose of the waterproof box is not only to prevent water splashing and protect the internal circuit and metal structure, but also to serve as the basis for fixedly installing the ice making device 6. The fixing frame 26 is firmly installed on the waterproof box, providing a stable installation platform. The ice making device 6 is installed through the fixing frame 26, making the entire structure more solid and reliable, avoiding displacement or loosening due to vibration during operation. This design ensures that the ice maker can maintain good performance and stability during long-term use. The fixing frame 26 not only has a supporting function, but also fixedly installs the mold closing motor 27, which makes the ice making process more intelligent and automated. The main function of the mold closing motor 27 is to control the closing and opening of the ice making mold. During the ice making process, the mold closing motor 27 drives the ice making lower mold 10 to accurately dock with the second mold 23 of the evaporative plate 11, ensuring the stability of the mold closure in each ice making cycle. Through such control, the entire ice making process becomes smoother and more efficient, avoiding errors caused by manual operation and improving ice making efficiency and ice quality. One side of the ice making lower mold 10 is rotationally connected with the fixing frame 26, which allows the ice making lower mold 10 to have a certain degree of freedom and can be appropriately flipped during demolding. After ice making is completed, the mold closing motor 27 starts to separate the ice making mold, and the ice making lower mold 10 is flipped by rotation to open the ice making device 6. This design not only simplifies the operation process, but also improves the demolding efficiency, ensuring that each ice block can be smoothly demolded and intact. In addition, the setting of the fixing frame 26 and the mold closing motor 27 also makes the ice making device 6 more modular and intelligent. Users can accurately control the mold closing motor 27 through the pre-set control system to realize automatic mold closing and demolding operation. This not only reduces manual intervention, but also improves the operation efficiency and ice making speed of the equipment. The intelligent control system can monitor each link of the ice making process in real time and adjust the operation parameters in time to ensure the stability and efficiency of each ice making cycle. In practical application, the design has excellent performance and operation convenience. Users can easily set ice making parameters through the control panel, and the cooperation of the mold closing motor 27 and the fixing frame 26 makes the ice making process fully automated, and users only need to wait for the finished ice blocks to fall into the ice storage basket. In the catering industry or other commercial use scenarios, this automation and efficiency can greatly improve the ice making efficiency and meet the large demand. During peak hours, this automatic ice maker can continuously and stably provide high-quality ice blocks to ensure service quality.

[0047] The mold closing motor 27 of the present application drives the first end of the connecting pull rod 28, the first end of the pull rod 28 is extended with a secondary rod 280, the second end of the pull rod 28 is connected to the other side of the ice making lower mold 10 through the tension spring 29, at the same time, the fixed frame 26 is fixedly installed with the contact switch group 30. The design further optimizes the mold closing and demolding process of the ice maker, making the whole operation more accurate and highly automated, and can automatically run without manual intervention. The main function of the mold closing motor 27 is to drive the pull rod 28 to realize the mold closing and demolding operation. By connecting the mold closing motor 27 with the first end of the pull rod 28, the movement of the pull rod 28 can be accurately controlled, ensuring that the ice making mold can be tightly joined when closing, improving the sealing and efficiency of ice making. The first end of the pull rod 28 is also extended with a secondary rod 280, which enhances the stability of the structure and the effectiveness of force transmission, making the pull rod 28 more uniform under stress, thereby improving the efficiency and accuracy of mold closing and demolding. The second end of the pull rod 28 is connected to the other side of the ice making lower mold 10 through the tension spring 29. The design of the tension spring 29 has elasticity and buffering effect, so that the mold can be closed and opened slowly and stably during the mold closing and demolding process. This not only prevents damage to the components caused by rapid mold closing or demolding, but also improves the stability and safety of the whole operation. This elastic connection method makes the ice making lower mold 10 not only tightly closed for ice making operation, but also smoothly and easily opened during demolding, ensuring the integrity of the ice cubes and the smoothness of the demolding. The contact switch group 30 installed on the fixed frame 26 further improves the automation and safety of the operation. The function of the contact switch group 30 is to monitor the state of the mold in real time during the ice making process, and through accurate contact feedback signals, the control system can make timely adjustments. During the mold closing process, when the ice making lower mold 10 and the second mold 23 are completely closed, the contact switch will send a signal to the control system to stop the mold closing motor 27, ensuring the accuracy and reliability of the mold closing state. Similarly, during the demolding process, when the mold is completely opened, the contact switch will also send a signal to indicate the control system to stop the demolding operation. This design not only realizes automatic control, but also greatly improves the safety of the operation, preventing misoperation. Through this design, the mold closing process of the ice maker becomes more accurate and efficient. The mold closing motor 27 drives the pull rod 28, the secondary rod 280 of the pull rod 28 enhances the stress effect, and the tension spring 29 ensures the stability of the process to ensure that the mold can perfectly cooperate with the mold closing and demolding operation. The contact switch group 30 monitors the mold state in real time to ensure that each step can be completed in the best state, improving the automation and reliability of the whole ice making process.

[0048] The contact switch group 30 of the present application includes a mold closing locking contact switch 31, a deicing contact switch 32, a mold closing landing contact switch 33 and a mold opening landing contact switch 34. The second end of the pull rod 28 touches and connects the mold closing locking contact switch 31 or the deicing contact switch 32, the ice-making lower mold 10 touches and connects the mold closing landing contact switch 33 through the top block 35, and the auxiliary rod 280 touches and connects the mold opening landing contact switch 34. The precise contact switch system design improves the automation control level and operation safety of the ice maker and ensures that the entire ice-making process can be accurately executed at each step. During ice making, the mold closing motor 27 drives the pull rod 28 to make the ice-making lower mold 10 combine with the evaporating plate 11, at this time, the second end of the pull rod 28 touches and connects the mold closing locking contact switch 31, and the control system determines that the ice-making lower mold 10 and the evaporating plate 11 are combined, after ice making is completed, the mold closing motor 27 drives the pull rod 28 to separate the ice-making lower mold 10 and the evaporating plate 11, at this time, due to the ice in the mold, the ice-making lower mold 10 and the evaporating plate 11 cannot be separated, the second end of the pull rod 28 touches and connects the deicing contact switch 32, at this time, the control system controls the electric pump to add water to the water injection bin 20, so that the first mold 19 and the ice block are separated, after the first mold 19 and the ice block are separated, the ice-making lower mold 10 continues to be flipped down, at this time, the top block 35 is separated from the mold closing landing contact switch 33, the control system determines that the first mold 19 is successfully demolded, stops adding water to the water injection bin 20, and switches the direction valve 36, so that the evaporator starts heating, the ice block is separated from the second mold 23, the demolding process is completed, the pull rod 28 continues to rotate, drives the ice-making lower mold 10 to continue to flip down, until the auxiliary rod 280 touches the mold opening landing contact switch 34, the system determines that the ice-making lower mold 10 is flipped down to the specified position, and the mold closing motor 27 stops working.

[0049] The refrigeration device of the present application is installed with a directional valve 36, which is connected with the copper pipe 14 and located between the refrigeration device and the evaporating plate 11, that is, the refrigeration device first connects the directional valve 36 through the copper pipe 14, and then connects the evaporating plate 11 through the copper pipe 14 from the directional valve 36. The design further optimizes the operation mechanism of the refrigeration system, making the ice-making process more efficient and controllable. The refrigeration device is the core component of the automatic ice maker, which is used for the task of refrigerant compression refrigeration and circulation. The directional valve 36 enhances the flexibility and efficiency of the refrigeration system. The function of the directional valve 36 is to control the direction of refrigerant flow, thereby switching the refrigeration device between different working modes. The directional valve 36 is located between the refrigeration device and the evaporating plate 11, which enables it to effectively control the supply path of the refrigerant from the compressor to the evaporating plate 11. Specifically, in the ice-making mode, the directional valve 36 switches to the corresponding path, making the refrigerant delivered to the evaporating plate 11 through the copper pipe 14, and the evaporating plate 11 absorbs heat and cools the water in the mold, making it quickly freeze into ice cubes. This process is very efficient because the refrigerant directly exchanges heat with the evaporating plate 11, which can quickly reduce the temperature in the mold and improve the ice-making speed. In the demolding mode, the directional valve 36 switches to another path, making the refrigerant flow to another part of the refrigeration device, such as an air cooler or a heating element, so that the evaporating plate 11 stops cooling and starts warming up. This operation is achieved by converting the evaporating plate 11 into a heater, which slightly warms up the evaporating plate 11, making the ice cubes easy to demold from the mold. Efficient heat conversion and flow control ensure the smooth progress of the ice cube demolding process, reducing the risk of ice cube breakage. The directional valve 36 automatically switches modes through a pre-set control program, which makes the entire ice-making and demolding process highly automated. Users only need to simply set the ice-making parameters, and the system can automatically control the state of the directional valve 36 according to the needs, switching the refrigeration and heating modes to achieve the optimal ice-making and demolding effect. This intelligent control not only improves the efficiency of the device operation, but also reduces human intervention and operation errors.
