[0047] As Figure 1As shown, the ice maker comprises a water supply device 1, an ice making device 2, an inlet and outlet water pipe 3, a drain valve 4 and a water adding switch valve 5, the ice making device 2 is provided with an inlet and outlet water port 212, a first end of the inlet and outlet water pipe 3 is communicated with the inlet and outlet water port 212, the second end of the inlet and outlet water pipe 3 is communicated with the drain valve 4, the water outlet of the drain valve 4 is communicated with a cold water tank 17, the first interface and the second interface of the water adding switch valve 5 are both communicated with the water supply device 1, and the third interface of the water adding switch valve 5 is communicated with the second end of the inlet and outlet water pipe 3.

[0048] The ice maker provided by the present application realizes that only one inlet and outlet water pipe 3 can be used for water inlet and water outlet of the ice making device 2, simplifies the pipeline structure of the ice maker and reduces the production cost.

[0049] It can be understood that, as shown, Figure 1 The water supply device 1 comprises a pure water tank 6 and a water pump 7, the pure water tank 6 is suitable for storing pure water, a first inlet of the pure water tank 6 is communicated with the first interface of the water adding switch valve 5, the inlet of the water pump 7 is communicated with the outlet of the pure water tank 6, the outlet of the water pump 7 is communicated with the second interface of the water adding switch valve 5, and the water pump 7 is suitable for pumping the pure water in the pure water tank 6 to the water inlet cavity.

[0050] It can be understood that, as shown, Figure 1 The ice maker further comprises a first vane pump 16, the cold water tank 17, a water purification device 18 and a cold water return switch valve 19, the water purification device 18 comprises a raw water tank, a PCB filter element and an RO filter element and the like, since the water purification device 18 is an existing device, the specific structure is not explained in detail here. The pure water outlet of the water purification device 18 is communicated with the second inlet of the pure water tank 6, and the water purification device 18 is used for inputting pure water into the pure water tank 6. The raw water outlet of the water purification device 18 is communicated with the first interface of the cold water return switch valve 19, the second interface of the cold water return switch valve 19 is communicated with the water outlet port, and the third interface of the cold water return switch valve 19 is communicated with the cold water tank 17 through the first vane pump 16. When the first interface of the cold water return switch valve 19 is communicated with the second interface of the cold water return switch valve 19, the raw water output by the water purification device 18 is delivered to the water outlet port; when the first interface of the cold water return switch valve 19 is communicated with the third interface of the cold water return switch valve 19, the raw water output by the water purification device 18 is delivered to the cold water tank 17. When the second interface of the cold water return switch valve 19 is communicated with the third interface of the cold water return switch valve 19, the first vane pump 16 can deliver the cold water in the cold water tank 17 to the water outlet port.

[0051] Further, the top of the pure water tank 6 is provided with a connecting port, the connecting port is communicated with the cold water tank 17 through a connecting pipe, and the excess water in the pure water tank 6 can flow into the cold water tank 17 through the connecting pipe.

[0052] It can be understood that, as shown in Figure 1 The ice maker further comprises a second impeller pump 21 and a square ice making device 222. The inlet of the second impeller pump 21 is in communication with the cold water tank 17, and the outlet of the second impeller pump 21 is in communication with the square ice making device 222, i.e. the outlet of the second impeller pump 21 is in communication with the water inlet of the spraying member.

[0053] It can be understood that, as shown in Figure 1 The water supply device 1 further comprises an instant heater 8 and a hot water switching valve 9. The inlet of the instant heater 8 is in communication with the outlet of the water pump 7. The first interface of the hot water switching valve 9 is in communication with the outlet of the instant heater 8, the second interface of the hot water switching valve 9 is in communication with the water outlet port, and the third interface of the hot water switching valve 9 is in communication with the second interface of the water adding switching valve 5. When the first interface of the hot water switching valve 9 is in communication with the second interface of the hot water switching valve 9, the water pump 7 can pump the pure water in the pure water tank 6 to the water outlet port. When the first interface of the hot water switching valve 9 is in communication with the third interface of the hot water switching valve 9, the water pump 7 can pump the pure water in the pure water tank 6 to the ice making device 2.

[0054] It can be understood that, as shown in Figure 2 The ice maker further comprises an outer housing and a cover. The water supply device 1, the ice making device 2, the water inlet and outlet pipe 3, the drain valve 4 and the water adding switching valve 5 are all arranged inside the outer housing. The outer housing is provided with an ice taking opening, and the position of the ice taking opening corresponds to the position of the ice making device 2. The cover is arranged at the ice taking opening and is hingedly connected to the outer housing.

[0055] It can be understood that, as shown in Figures 4 to 8 The ice making device comprises a first evaporator assembly 10 and a water box assembly 20. The water box assembly 20 comprises a water box body 210, an inner housing 220 and a pressing mechanism 230. The inner housing 220 and the first evaporator assembly 10 enclose a first ice making cavity 221. The water box body 210 is arranged on the side of the inner housing 220 away from the first evaporator assembly 10, and the water box body 210 and the inner housing 220 enclose a water inlet cavity 211. The inner housing 220 is provided with a turbulence hole 222 in communication with the water inlet cavity 211 and the first ice making cavity 221. The material of the inner housing 220 is a flexible material, such as rubber or silicone. The pressing mechanism 230 is arranged on the water box body 210. When the ice is removed, the pressing mechanism 230 is adapted to extrude and deform the inner housing 220, so as to separate the ice block from the inner housing 220.

[0056] According to the ice making device provided by the application, the inner shell 220 is made of flexible material, so that the inner shell 220 can easily deform under external force and recover. During ice removal, the pressing mechanism 230 is pressed by hand, and the pressing mechanism 230 further extrudes the flexible inner shell 220 under the pressure to cause local or overall deformation of the inner shell 220. This ice block separation method through extrusion deformation simplifies the overall mechanical structure, reduces the production cost, and has higher reliability and longer service life due to the reduction of moving parts. During the entire ice removal operation, the pressing mechanism 230 always acts on the outer wall of the inner shell 220, avoiding direct contact between the pressing mechanism 230 and the ice blocks inside the inner shell 220, and ensuring the food-grade hygiene of the ice blocks.

[0057] It can be understood that the first ice making cavity 221 is spherical, and the inner shell 220 is hemispherical at this time, and the ice blocks produced are spherical ice. Of course, the first ice making cavity 221 can also be an ellipsoid, an animal shape or other shapes, and the shape of the inner shell 220 is adjusted according to the shape of the first ice making cavity 221.

[0058] It can be understood that, as shown in Figure 5 and Figure 7 The first evaporator assembly 10 includes a first evaporator, and the first evaporator is provided with a first accommodating cavity on the side (i.e. the upper side of the first evaporator) facing the water box assembly 20. The inner shell 220 is provided with a second accommodating cavity on the side facing the first evaporator assembly 10, and the first accommodating cavity and the second accommodating cavity are both hemispherical. When the inner shell 220 is attached to the top of the first evaporator, the first accommodating cavity and the second accommodating cavity are communicated to form a spherical first ice making cavity 221. In this embodiment, the first evaporator is provided with two first accommodating cavities, and the two first accommodating cavities are arranged at intervals along the length direction of the first evaporator.

[0059] The first evaporator includes a first shell 11 and a second shell 12, and the materials of the first shell 11 and the second shell 12 are both metal. The first accommodating cavity is arranged on the side of the first shell 11 away from the second shell 12 to form a convex part on the side of the first shell 11 facing the second shell 12. The second shell 12 is provided with a recessed part on the side facing the first shell 11, and the convex part is located in the recessed part. The edge of the first shell 11 is welded and connected with the edge of the second shell 12 in a sealed manner, and the convex part and the recessed part are spaced apart by a certain distance to form a medium flow channel. One end of the second shell 12 is provided with a medium inlet 14, and the other end is provided with a medium outlet 15. The medium inlet 14 and the medium outlet 15 are both communicated with the medium flow channel. During the operation of the ice maker, the cooling medium flows into the medium flow channel through the medium inlet 14 and fills the medium flow channel. The cooling medium exchanges heat with the water in the medium flow channel and the first ice making cavity 221, so that the water freezes into ice blocks. The medium after heat exchange flows out of the medium flow channel through the medium outlet 15.

[0060] Further, the first evaporator further comprises a solder composite plate 13 in a hollow structure, which is sleeved on the outer periphery of the convex part, and the edge of the first shell 11 is welded and connected with the edge of the second shell 12 through the solder composite plate 13.

[0061] It can be understood that, as shown in Figure 5 and Figure 7 The water box body 210 is provided with a mounting hole at the top of the water box body 210 to facilitate direct operation after opening the cover 41 of the ice maker. Of course, the position of the mounting hole is not limited to this, and it can also be arranged at other positions of the water box body 210.

[0062] The pressing mechanism 230 comprises a pressing piece 231 and an elastic piece 232. The pressing piece 231 is vertically arranged, and the first end of the pressing piece 231 is movably arranged in the mounting hole. The pressing piece 231 is located above the inner shell 220, and the number of the pressing piece 231 is the same as that of the inner shell 220. The pressing piece 231 and the inner shell 220 are arranged one by one. The elastic piece 232 is connected with the pressing piece 231. The elastic piece 232 can store and release energy after the external force is removed, so that the pressing piece 231 automatically returns to the initial position after extruding the inner shell 220, realizes the automatic reset after pressing, and does not need to be manually reset by the user, thereby improving the convenience of operation and the efficiency of continuous use. The elastic piece 232 is suitable for switching between an initial state and a deformed state. In the initial state, the first end of the pressing piece 231 is separated from the inner shell 220. In the deformed state, by applying an external force to the pressing piece 231, the first end of the pressing piece 231 abuts against and extrudes the flexible inner shell 220 to deform it. The deformation of the flexible inner shell 220 is used to break the adhesion between the ice block and the surface of the shell, so as to separate the ice block from the inner shell 220, thereby achieving the effect of easily and conveniently removing the ice. This method not only has the advantages of simple operation and labor saving, but also can effectively avoid the problems of ice block fragmentation and mold damage caused by traditional knocking and twisting methods.

[0063] It can be understood that, as shown in Figure 5 and Figure 7As shown, the elastic member 232 includes a compression spring and is sleeved on the outer periphery of the pressing member 231. The compression spring is coaxial with the pressing member 231, which makes the overall structure compact and occupies less space, and can ensure that the pressing member 231 is uniformly stressed during movement, thereby realizing stable and smooth reciprocating motion. The first end of the compression spring abuts against the outside of the water box body 210, and the second end of the pressing member 231 is provided with a pressing portion 238. The cross-sectional area of the pressing portion 238 is greater than that of the compression spring, and the second end of the compression spring abuts against the pressing portion 238. The pressing portion 238 not only has a larger contact area, which improves the comfort and operational convenience of the user when pressing, but also serves as a limiting and stressed end of the spring, ensuring the smooth transmission of pressure and spring elasticity. Of course, the specific type of the elastic member 232 is not limited to this, and it can also be a tension spring or other types of springs.

[0064] As shown, Figure 5 and Figure 7 As shown, the outside of the water box body 210 is provided with a guide sleeve 233, which provides precise guidance for the reciprocating motion of the pressing member 231, ensuring that the pressing member 231 always moves stably along the predetermined path, thereby avoiding shaking or deviation during movement. The pressing member 231 is located inside the guide sleeve 233, and the guide sleeve 233 is coaxially arranged with the pressing member 231. The compression spring is located between the guide sleeve 233 and the pressing member 231, which contains the spring inside the guide structure, protecting the spring from external impurities and damage, and making the overall structure more neat and compact. The pressing portion 238 is in sliding fit with the guide sleeve 233, and the upper end of the pressing portion 238 is in sliding contact with the inner wall of the guide sleeve 233, which ensures smooth and smooth pressing stroke, improves the operation feel and reliability of the mechanism.

[0065] As shown, Figure 8 As shown, the ice making device further comprises a handle 234, and the number of guide sleeves 233 is at least two. The handle 234 is connected with two of the guide sleeves 233, and the handle 234 is arranged to facilitate the removal of the water box assembly 20 from the mounting cavity of the support 215. Preferably, the guide sleeve 233 is provided with two guide sleeves 233, which are arranged at the top of the water box body 210 along the length direction of the water box body 210. One end of the handle 234 is connected with one guide sleeve 233, and the other end of the handle 234 is connected with the other guide sleeve 233, thereby forming a complete handle 234 structure, which facilitates the user to easily and stably take out or put in the entire ice making device with one hand. The handle 234 is integrally formed with the guide sleeve 233, which reduces the number of components, simplifies the production process and reduces the manufacturing cost. At the same time, the integrated structure also ensures the strength and durability of the connection, avoiding the loosening problem that may occur after long-term use.

[0066] As shown,Figure 5 and Figure 7 As shown in FIGS. 1 1 and 12, the pressing mechanism 230 further comprises a sealing ring 235, which is sleeved on the first end of the pressing piece 231 and sealingly cooperates with the pressing piece 231. In the initial state, the sealing ring 235 abuts against and sealingly cooperates with the edge of the mounting hole near the water inlet cavity 211, so as to prevent the water in the water inlet cavity 211 from flowing out through the gap between the pressing piece 231 and the mounting hole. In the deformed state, the sealing ring 235 is separated from the edge of the mounting hole near the water inlet cavity 211.

[0067] The pressing mechanism 230 further comprises a sealing ring 235, which is sleeved on the first end of the pressing piece 231 and sealingly cooperates with the pressing piece 231. In the initial state, the elastic force of the elastic piece 232 causes the sealing ring 235 to abut against and sealingly cooperate with the edge of the mounting hole near the water inlet cavity 211, so as to form a waterproof barrier and prevent the water in the water inlet cavity 211 from flowing out through the gap between the pressing piece 231 and the mounting hole after water injection, thereby improving the sealing performance of the water box assembly 20. In the deformed state, when the pressing piece 231 is pressed down, the sealing ring 235 moves downward and is separated from the edge of the mounting hole. At this time, since the water in the water inlet cavity 211 has been discharged, no water will flow out although there is a gap between the pressing piece 231 and the mounting hole.

[0068] As shown in FIGS. 1 1 and 12, the outer circumferential surface of the first end of the pressing piece 231 is provided with a positioning groove 236, and the sealing ring 235 is embedded in the positioning groove 236. Through the positioning groove 236, the axial movement or falling off of the sealing ring 235 during frequent reciprocating movement of the pressing piece 231 is effectively prevented, and the stability and reliability of the sealing structure are greatly improved, thereby ensuring the long-term and effective sealing effect. Figure 5 Figure 7 As shown in FIGS. 1 1 and 12, the outer circumferential surface of the first end of the pressing piece 231 is provided with a positioning groove 236, and the sealing ring 235 is embedded in the positioning groove 236. Through the positioning groove 236, the axial movement or falling off of the sealing ring 235 during frequent reciprocating movement of the pressing piece 231 is effectively prevented, and the stability and reliability of the sealing structure are greatly improved, thereby ensuring the long-term and effective sealing effect.

[0069] As shown in FIGS. 1 1 and 12, the outer circumferential surface of the first end of the pressing piece 231 is provided with a positioning groove 236, and the sealing ring 235 is embedded in the positioning groove 236. Through the positioning groove 236, the axial movement or falling off of the sealing ring 235 during frequent reciprocating movement of the pressing piece 231 is effectively prevented, and the stability and reliability of the sealing structure are greatly improved, thereby ensuring the long-term and effective sealing effect.

[0070] As shown in FIGS. 1 1 and 12, the outer circumferential surface of the first end of the pressing piece 231 is provided with a positioning groove 236, and the sealing ring 235 is embedded in the positioning groove 236. Through the positioning groove 236, the axial movement or falling off of the sealing ring 235 during frequent reciprocating movement of the pressing piece 231 is effectively prevented, and the stability and reliability of the sealing structure are greatly improved, thereby ensuring the long-term and effective sealing effect. Figure 5 Figure 7 ​​As shown, the first end of the pressing piece 231 is provided with a contact portion 237, the cross-sectional area of which is larger than that of the stem of the pressing piece 231, which is designed to increase the contact area of the pressing piece 231 with the inner shell 220, so that when pressure is applied, the pressure acting on the flexible inner shell 220 can be effectively dispersed, avoiding the risk of the pressing piece 231 piercing or damaging the inner shell 220 due to excessive stress concentration, significantly improving the durability and reliability of the mechanism. At the same time, the larger contact area also allows the pressure to be transmitted more evenly to the inner shell 220, causing it to deform more gently and widely, thereby more efficiently breaking the adhesion between the ice cubes and the shell, making the ice removal operation easier and more complete.

[0071] It can be understood that the side of the inner shell 220 facing the pressing piece 231 is provided with a positioning sleeve, and when the pressing piece 231 moves downward, its first end is first inserted into the positioning sleeve, providing precise positioning for the pressing piece 231. Then the pressing piece 231 continues to move downward, deforming the inner shell 220 connected to the positioning sleeve by extrusion. Since the pressing position is precisely positioned, it ensures that each pressing can act on the most effective deformation area of the inner shell 220, thereby achieving efficient and reliable ice removal. The positioning sleeve can position the lower end of the pressing piece 231, fundamentally preventing the lower end of the pressing piece 231 from shifting due to uneven stress or gap tolerance, avoiding the situation where the inner shell 220 is partially damaged or ice removal fails due to misaligned pressing, greatly improving the durability of the product and the success rate of user operation.

[0072] It can be understood that the spoiler hole 222 has multiple, by setting multiple spoiler holes 222 as communication channels, ensuring the redundancy and efficiency of water flow, even if individual spoiler holes 222 are slightly blocked due to icing, the remaining spoiler holes 222 can still maintain normal water exchange, ensuring the stability of the ice making process; multiple spoiler holes 222 are evenly distributed in the inner shell 220, ensuring that water flows at every point in the first ice making cavity 221, thereby establishing a uniform temperature field and flow field in the first ice making cavity 221, allowing water in the water inlet cavity 211 to flow and circulate with water in the first ice making cavity 221. In the slow process of water freezing into ice, gases and impurities in the water will be carried away by the continuously flowing liquid water and will not be trapped in ice crystals, ultimately ensuring that the ice cubes produced are bubble-free and crystal clear, significantly improving the quality of the ice cubes.

[0073] It can be understood that, as Figures 14 to 17As shown, the ice making device further comprises a disturbance component 30, the water box assembly 20 is a cuboid, and the water box assembly 20 has a water inlet cavity 211 inside; the first evaporator assembly 10 and the water box assembly 20 enclose a first ice making cavity 221, and the first ice making cavity 221 is in communication with the water inlet cavity 211 through a disturbance hole 222; the disturbance component 30 comprises a driving mechanism 310, a disturbance mechanism 320, a first magnetic attraction mechanism 330 and a second magnetic attraction mechanism 340, the driving mechanism 310 and the first magnetic attraction mechanism 330 are both arranged outside the water box assembly 20, the driving mechanism 310 is connected with the first magnetic attraction mechanism 330, the disturbance mechanism 320 and the second magnetic attraction mechanism 340 are both arranged inside the water inlet cavity 211, the disturbance mechanism 320 is connected with the second magnetic attraction mechanism 340, the first magnetic attraction mechanism 330 is magnetically attracted to the second magnetic attraction mechanism 340, the driving mechanism 310 is adapted to drive the disturbance mechanism 320 to rotate, and the disturbance mechanism 320 is adapted to drive the water in the water inlet cavity 211 to flow.

[0074] The ice making device provided by the application has the advantages that Figure 14 As shown, the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340 are magnetically attracted to each other, thereby achieving the connection between the driving mechanism 310 and the disturbance mechanism 320, so that the driving mechanism 310 can drive the disturbance mechanism 320 to rotate through the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340, without the need to open a hole in the water box assembly 20 to connect the driving mechanism 310 and the disturbance mechanism 320, thereby avoiding the problem of water leakage and simplifying the structure of the ice maker.

[0075] The first magnetic attraction mechanism 330 is arranged outside the water box assembly 20 and connected with the driving mechanism 310, while the second magnetic attraction mechanism 340 is arranged inside the water box assembly 20 and connected with the disturbance mechanism 320, power transmission is achieved by the magnetic attraction between the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340, and finally a non-contact connection is achieved between the driving mechanism 310 and the disturbance mechanism 320, so that when the driving mechanism 310 located outside rotates, the rotating magnetic field generated thereby can penetrate the side wall of the water box assembly 20, thereby stably driving the disturbance mechanism 320 located inside the water box to rotate synchronously through magnetic force. In this way, the whole process of power transmission does not need to open any through hole for installing a transmission shaft on the water box assembly 20, thereby avoiding the need to set a sealing element due to the transmission shaft penetrating through the water box assembly 20 in the mechanical transmission mode, and thus avoiding the problem of water leakage that may occur due to aging, wear or improper installation of the sealing element, greatly improving the safety and durability of the product. Furthermore, since the complex sealing structure is omitted, the overall structure of the ice maker is simplified, the number of parts is reduced, and the production cost is lowered, so that the assembly process is more convenient and efficient.

[0076] It can be understood that Figure 5 and Figure 7As shown, the water box assembly 20 comprises a water box body 210 and an inner housing 220, the first evaporator assembly 10 and the inner housing 220 enclose a first ice making cavity 221, the water box body 210 is arranged on the side of the inner housing 220 away from the first evaporator assembly 10, the water box body 210 and the inner housing 220 enclose a water inlet cavity 211, and a turbulence hole 222 is arranged on the inner housing 220. The turbulence hole 222 serves as a passage connecting the water inlet cavity 211 and the first ice making cavity 221, not only achieving continuous supply of water required for ice making, but more importantly, being able to guide water flow to circulate between the two cavities in a preset manner, cooperating with the work of the disturbance mechanism 320, thereby effectively discharging air dissolved in water, generating crystal clear, bubble-free high-quality ice cubes.

[0077] It can be understood that, Figure 15 As shown, the disturbance mechanism 320 comprises a connecting rod 321 and a turbulence sheet 322, the connecting rod 321 is arranged in the water inlet cavity 211, the connecting rod 321 is horizontally arranged along the width direction of the water box assembly 20, the connecting rod 321 is connected with the water box body 210, the connecting rod 321 is adapted to provide a mounting base for the second magnetic attraction mechanism 340, and the second magnetic attraction mechanism 340 is rotatably sleeved on the first end of the connecting rod 321; the turbulence sheet 322 is adapted to drive water in the water inlet cavity 211 to flow, the turbulence sheet 322 is fixedly connected with the second magnetic attraction mechanism 340, so that the rotation torque transmitted by the external driving force can be directly and losslessly transmitted to the turbulence sheet 322, thereby making it efficiently agitate the water body in the water inlet cavity 211, form a continuous flow, accelerate the discharge of air dissolved in water, and make the water temperature in the water inlet cavity 211 uniform, which helps to produce high-quality ice cubes with fewer bubbles and more pure transparency.

[0078] It can be understood that, as Figure 17 As shown, the connecting rod 321 comprises a connecting rod body 323 and a plug-in rod 324, the side wall of the water inlet cavity 211 away from the first magnetic attraction mechanism 330 is provided with a socket, and the upper part of the socket is provided with a socket. By arranging the socket on the side wall of the water inlet cavity 211 away from the first magnetic attraction mechanism 330, and arranging the socket on the upper part thereof, the first end of the connecting rod body 323 can be directly clamped in the socket, realizing quick installation and positioning without tools, greatly simplifying the assembly steps, improving the production efficiency, and also providing great convenience for subsequent possible maintenance or cleaning. The second end of the connecting rod body 323 is provided with a plug-in hole, the first end of the plug-in rod 324 is plugged into the plug-in hole, and the cross section of the plug-in rod 324 is a non-circular cross section, ensuring that the plug-in rod 324 and the connecting rod body 323 are coaxially arranged and cannot relatively rotate with each other. By adopting such a setting mode, not only is the injection molding difficulty of a single slender part reduced, but more importantly, it makes it possible to complete the installation of the transverse support rod in the closed cavity, ensuring that the combined rod body has good overall rigidity and torque transmission capacity.

[0079] On the other side of the water inlet chamber 211, near the side wall of the first magnetic attraction mechanism 330, a blind hole is correspondingly provided. The second end of the plug rod 324 is inserted into this blind hole, thereby fixing both ends of the connecting rod 321. The blind hole provides a stable support point for the connecting rod 321 while maintaining the closed integrity of the water box wall. Preferably, the inner diameter of the blind hole gradually increases in the direction away from the first magnetic attraction mechanism 330, thus forming a tapered guide opening. This plays a guiding role in the assembly process, allowing the end of the plug rod 324 to be easily and accurately aligned and inserted into the blind hole, significantly reducing the assembly difficulty, avoiding component damage caused by misalignment or jamming, and further improving the convenience and reliability of installation.

[0080] It is understandable that, such as Figure 17 As shown, the connecting rod 321 also includes a rotating sleeve 325, which is rotatably fitted onto the insertion rod 324. The second magnetic attraction mechanism 340 is fitted onto the outer circumferential surface of the rotating sleeve 325. The rotating sleeve 325 is rotatably fitted onto the insertion rod 324, which serves as a fixed shaft, thus forming a dedicated sliding bearing structure between the fixed insertion rod 324 and the rotating component. By concentrating the rotational friction entirely between the inner surface of the rotating sleeve 325 and the outer surface of the insertion rod 324, a self-lubricating material with a lower coefficient of friction can be used to manufacture the rotating sleeve 325, significantly reducing rotational resistance. This makes the start-up and operation of the entire disturbance mechanism 320 smoother and more stable, and greatly improves the durability and service life of the rotating component. The second magnetic attraction mechanism 340 is fitted onto and fixedly connected to the outer circumferential surface of the rotating sleeve 325, so that the second magnetic attraction mechanism 340 itself no longer needs to directly rotate relative to the fixed insertion rod 324, extending the service life of the second magnetic attraction mechanism 340.

[0081] It is understandable that, such as Figure 17 As shown, a limiting ring 326 is integrally formed or fixedly provided on the outer circumferential surface of the plug rod 324, providing a rigid limiting mechanism for the axial movement of the rotating sleeve 325, so that the first side of the rotating sleeve 325 forms a limiting engagement with the end face of the limiting ring 326. Based on this, by simultaneously forming a limiting engagement with the end face of the second end of the connecting rod body 323 on the other side of the rotating sleeve 325, the rotating sleeve 325 is precisely "clamped" and constrained within a predetermined working area between the two. This bidirectional limiting structure effectively prevents any unnecessary axial movement or drift of the rotating sleeve 325 during rotation, ensuring that the second magnetic attraction mechanism 340 fixed thereon always maintains the optimal magnetic coupling distance and alignment position with the external first magnetic attraction mechanism 330, thereby ensuring the high efficiency and stability of power transmission. It also avoids collisions and friction between the rotating component and the inner wall of the water cavity or other components due to axial movement, ensuring the smooth operation of the equipment.

[0082] It can be understood that, as shown in Figure 17 The second magnetic attraction mechanism 340 includes a mounting seat 341 and a first magnet 342. The mounting seat 341 is provided with a center hole, so that the entire mounting seat 341 can be directly sleeved on the outer circumferential surface of the rotating sleeve 325 through the center hole and fixedly connected thereto. The spoiler 322 is arranged on the side of the mounting seat 341 away from the first magnetic attraction mechanism 330. Such a layout mode effectively separates the magnetic coupling area responsible for power transmission from the fluid action area responsible for stirring water flow, so that the side wall of the water box body 210 plays a role of physical isolation, thereby ensuring that the first magnet 342 and the second magnet 331 are as close to each other as possible to obtain the maximum magnetic torque, while avoiding the interference of the spoiler 322 with the magnetic field during rotation, and realizing the optimization of the two functions of power transmission and fluid disturbance. The first magnet 342 is arranged on the mounting seat 341, and the mounting seat 341 provides a mounting basis for the first magnet 342, ensuring that all the first magnets 342 are uniformly and firmly distributed in the circumferential direction.

[0083] It can be understood that, by arranging four first grooves equidistantly spaced in the circumferential direction on the side of the mounting seat 341 away from the first magnetic attraction mechanism 330, a mounting basis is provided for the four first magnets 342, ensuring that all the first magnets 342 are uniformly distributed in the circumferential direction, thereby realizing good dynamic balance performance and significantly reducing vibration and noise during rotation, so that the disturbance mechanism 320 operates more stably; at the same time, the four first magnets 342 are embedded one by one in the four grooves, ensuring that the first magnets 342 will not be displaced under the action of high-speed rotation and magnetic force, and ensuring the stability and reliability of torque transmission.

[0084] A limiting step is arranged on the edge of the center hole away from the first magnetic attraction mechanism 330, and the spoiler 322 is sleeved on the limiting step. By arranging a limiting step on the edge of the center hole of the mounting seat 341 away from the first magnetic attraction mechanism 330, a fixing basis is provided for the installation of the spoiler 322, realizing the quick installation of the spoiler 322. After installation, the spoiler 322 also covers the opening of the first groove. On the one hand, the spoiler 322 itself is used as a cover plate to completely encapsulate the first magnet 342 in a dry groove cavity, and through such encapsulation, direct contact between the magnet and water is effectively avoided, ensuring the cleanliness and safety of the ice-making water; on the other hand, it also uses the limiting step of the mounting seat 341 to realize its own fixation, greatly reducing the number of parts and simplifying the assembly process.

[0085] It can be understood that the first magnetic attraction mechanism 330 includes a rotating seat and a second magnet 331, and the rotating seat is connected with the connecting shaft of the driving mechanism 310; the second magnet 331 is arranged on the rotating seat and is in magnetic attraction cooperation with the first magnet 342.

[0086] It can be understood that, as shown in Figure 14 The rotating seat includes a rotating seat body 332 and a connecting piece 333. The rotating seat body 332 is disc-shaped, so that the mass distribution is uniform when rotating, which is beneficial to realize dynamic balance, thereby ensuring the stability of the rotating process and effectively reducing the vibration and noise during operation. Four second grooves are arranged on the side of the rotating seat body 332 away from the second magnetic attraction mechanism 340, and the four second grooves are equidistantly arranged circumferentially. The equidistant arrangement enables the weight and magnetic force of the subsequently installed second magnets 331 to be uniformly distributed, avoiding unstable rotation or uneven magnetic force due to eccentricity. There are four second magnets 331, and the four second magnets 331 are correspondingly embedded in the four second grooves. Of course, the number of second grooves is not limited to this, and is determined according to the number of second magnets 331. The connecting piece 333 is disc-shaped, and is sleeved on the connecting shaft of the driving mechanism 310, thereby realizing reliable connection between the rotating seat and the external driving source. The connecting piece 333 is located on the side of the rotating seat body 332 away from the second magnetic attraction mechanism 340 and covers the opening of the second groove.

[0087] It can be understood that the number of first magnets 342 is the same as the number of second magnets 331, and the positions of the first magnets 342 correspond one-to-one to the positions of the second magnets 331. Such an arrangement ensures that a stable and balanced magnetic field coupling can be formed between the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340, thereby maximizing the efficiency of magnetic force transmission and ensuring that power can be transmitted from the driving mechanism to the spoiler 322 without loss and with high efficiency. The four first magnets 342 are arranged symmetrically in pairs. Such symmetrical arrangement enables the first magnetic attraction mechanism 330 to have excellent dynamic balance performance when rotating, effectively avoiding vibration and noise caused by uneven mass distribution and ensuring the stability and quietness of the device operation. The magnetic poles of the adjacent two first magnets 342 are oppositely arranged, and the N and S poles are alternately arranged to form a sharp magnetic field gradient between the adjacent magnets. Such an arrangement can generate stronger magnetic forces, whether attractive or repulsive, when rotating, thereby providing strong driving torque for rotation and ensuring reliable synchronous rotation. The magnetic pole of the end of the first magnet 342 close to the second magnet 331 is the same as the magnetic pole of the end of the second magnet 331 close to the first magnet 342. When the first magnet 342 on the driving side rotates, the repulsive force generated thereby will "push" the second magnet 331 on the driven side to rotate synchronously, thereby realizing non-contact torque transmission. Such repulsive force coupling transmits power.

[0088] It can be understood that one of the connecting piece 333 and the rotating seat body 332 is provided with a plurality of clamping tongues which are arranged in a circumferential direction, and the other of the connecting piece 333 and the rotating seat body 332 is provided with a plurality of clamping through holes which are arranged in a circumferential direction, and the plurality of clamping tongues are correspondingly clamped in the edges of the clamping through holes after passing through the clamping through holes. This connection mode through the elastic clamping tongues and the clamping through holes can be completed by only aligning and pressing, and the operation is extremely simple. Thus, the quick connection between the connecting piece 333 and the rotating seat body 332 is realized, and the assembly mode of the connecting piece 333 and the rotating seat body 332 is simplified. This assembly mode without tools and additional fasteners (such as screws) shortens the assembly time on the production line, reduces the skill requirement for the operator, improves the production efficiency, and finally directly translates into the reduction of manufacturing cost and the improvement of product capacity. Of course, the connection mode of the connecting piece 333 and the rotating seat body 332 is not limited to this, and other detachable connection modes can also be used.

[0089] It can be understood that, as shown in Figures 8 to 13 At least two water inlet and outlet ports 212 which communicate with the water inlet cavity 211 are arranged on the side wall of the water box body, and the at least two water inlet and outlet ports 212 are arranged in a vertical direction. By arranging at least two water inlet and outlet ports 212 which communicate with the water inlet cavity 211 on the side wall of the water box body 210, a plurality of water flow channels are provided, which improves the redundancy and reliability of the pipeline compared with the design of a single water inlet and outlet port 212, and avoids the risk of failure of the entire ice melting process due to blockage of a single pipeline. By arranging the at least two water inlet and outlet ports 212 in a vertical direction, even if the lower water inlet and outlet port 212 is blocked by ice, the upper water inlet and outlet port 212 remains unblocked and can be used as a backup channel to ensure that the remaining cold water in the water inlet cavity 211 can be smoothly discharged to provide conditions for subsequent injection of ice melting water. Subsequently, the ice melting water with a higher temperature can be efficiently injected into the water inlet cavity 211 through the unblocked upper water inlet and outlet port 212 (or through both water inlet and outlet ports after the lower water inlet and outlet port is unblocked), and the ice in the cavity is quickly and uniformly heated and melted, thereby effectively solving the problem of interruption of the traditional single water outlet design during ice melting, ensuring the success rate of ice melting operation and the continuity and stability of the entire ice making device operation, and ensuring the normal operation of ice melting.

[0090] It can be understood that, as shown in Figure 8As shown, the side wall of the water box body 210 is further provided with an overflow port 213. When water is injected into the water inlet cavity 211, the overflow port 213 provides a smooth discharge channel for the air in the water inlet cavity 211, effectively avoiding the problem of poor water injection or insufficient water injection caused by the back pressure generated by the formation of a closed air chamber in the water inlet cavity 211. The overflow port 213 is located on one side of the upper water inlet and outlet port 212, and is adapted to discharge the air and / or excess water in the water inlet cavity 211. By limiting the highest liquid level in the water inlet cavity 211 through the specific height position, the overflow port 213 can automatically discharge water exceeding the standard water amount, thereby achieving precise control of the water amount for each ice making.

[0091] As can be understood, as shown, Figure 12 The water box assembly 20 further includes a baffle 214 vertically arranged on the inner side of the side wall of the water box body 210. The baffle 214 covers the overflow port 213, and a flow channel is formed between the baffle 214 and the side wall of the water box body 210, which is in communication with the overflow port 213. The flow channel provides a dedicated and relatively isolated stable channel for air and excess water, ensuring smooth air and water discharge functions. The upper end and the lower end of the baffle 214 are both provided with a connection port in communication with the flow channel. Specifically, the height of the port at the upper end of the baffle 214 is greater than the height of the overflow port 213, ensuring that the upper port mainly serves as a high-level air discharge channel, which can efficiently discharge the air squeezed in the cavity during water injection, avoiding air resistance affecting the water injection speed and water amount accuracy. At the same time, the height of the port at the lower end of the baffle 214 is less than the height of the overflow port 213. When ice is removed, even if the port at the lower end of the baffle 214 is temporarily blocked by ice or ice-water mixture due to its proximity to the bottom of the water body, the upper end port, which is much higher than the ice sealing area, remains unblocked and can serve as a reliable pressure relief and air discharge channel, providing an outlet for the air or water vapor generated during the subsequent injection of ice melting water, thereby completely solving the potential failure point of poor air discharge and the inability of ice melting water to be smoothly injected due to the blockage of a single channel. The upper end port can also be used for air discharge, greatly improving the ice removal success rate and operation reliability of the equipment under complex working conditions.

[0092] As can be understood, the number of water inlet and outlet ports 212 is two, and the two water inlet and outlet ports 212 are on the same vertical line. The height of the overflow port 213 is less than or equal to the height of the upper water inlet and outlet port 212.

[0093] It can be understood that the baffle 214 is provided with a plurality of overflow holes in direct communication with the flow channel, thereby increasing the total flow area of air exhaust and effectively improving the efficiency and speed of air exhaust; and the plurality of overflow holes are arranged in the up-down direction at intervals, so that at least one overflow hole is above the water surface regardless of the water level in the flow channel, and the accumulated air in the upper layer can be smoothly exhausted, thereby avoiding the problem that part of the air is trapped in the flow channel and cannot be exhausted due to changes in water level, and ensuring the stability of the exhaust effect.

[0094] It can be understood that, as shown in Figure 9 , the ice making device further comprises a bracket 215, the inside of the bracket 215 is provided with a mounting cavity, which provides an integrated mounting space for the first evaporator assembly 10 and the water box assembly 20, so that the structure of the entire device is more compact, and effectively supports and protects the internal components; the top of the bracket 215 is provided with an opening in communication with the mounting cavity, so as to facilitate the installation personnel to put or take out the core components such as the first evaporator assembly 10 and the water box assembly 20 from above, simplify the assembly and subsequent maintenance process, and improve the production and maintenance efficiency; the first evaporator assembly 10 and the water box assembly 20 are stacked in the mounting cavity in the direction from bottom to top.

[0095] It can be understood that, as shown in Figure 9 and Figure 13 , the ice making device further comprises a water and gas connecting seat 240, the side wall of the bracket 215 is provided with a positioning groove, and the water and gas connecting seat 240 is embedded in the positioning groove, which provides an accurate mounting position for the water and gas connecting seat 240, ensuring that it can be quickly and accurately installed to the predetermined position, and the embedded mode ensures the stability and reliability of the connection between the two, avoiding loosening or misalignment due to equipment vibration and other factors; the water and gas connecting seat 240 is centrally provided with an overflow connecting port 241 and at least two water inlet and outlet connecting ports 242, by integrating a plurality of fluid interfaces on this one independent modular component, the structure of the bracket 215 body is simplified, so that it does not need to open a plurality of waterway holes, thereby significantly reducing the processing complexity and manufacturing cost of the bracket 215; the water and gas connecting seat 240 is attached to the side wall of the water box body 210, so that the water inlet and outlet connecting ports 242 and the water inlet and outlet ports 212 can be in one-to-one correspondence and communication, and the overflow connecting port 241 and the overflow port 213 are in communication.

[0096] It can be understood that the inner diameter of the water inlet and outlet connecting port 242 is larger than the inner diameter of the water inlet and outlet port 212. By making the inner diameter of the water inlet and outlet connecting port 242 larger than the inner diameter of the water inlet and outlet port 212, even if there is a certain deviation in the vertical or horizontal direction during the installation of the water box assembly 20, as long as the profile range of the water inlet and outlet port 212 falls within the profile range of the water inlet and outlet connecting port 242, an effective flow cross section can still be formed between the two, thereby ensuring the connection of the water path, which greatly reduces the installation precision requirement of the water and gas connecting seat 240.

[0097] It can be understood that the edge of the water inlet and outlet connecting port 242 is provided with a first annular sealing gasket 243, which fills the small gap between the connecting surfaces by utilizing its own elasticity, and the first annular sealing gasket 243 is in sealing cooperation with the edge of the water inlet and outlet port 212, which ensures that during the water inlet or water outlet process, the water flow will not leak from the interface; Similarly, the edge of the overflow connecting port 241 is also provided with a second annular sealing gasket 244, which is in sealing cooperation with the edge of the overflow port 213, effectively preventing the leaked water or discharged air from leaking into the device from the interface, avoiding the risk of possible electrical short circuit or component rust. Preferably, the side wall of the bracket 215 or the side wall of the water box body 210 is inclined, when the water box body 210 is installed downward, the water box body 210 will be subjected to the horizontal component force of the inclined side wall of the bracket 215, thereby pressing the first annular sealing gasket 243 and the second annular sealing gasket 244 more tightly. This self-locking design utilizes the weight and installation action of the assembly to continuously apply and enhance the sealing pressure, greatly improving the long-term reliability and sealing performance of the connection, even if the sealing gasket is worn out after long-term use, this structure can compensate to a certain extent.

[0098] It can be understood that the water inlet and outlet pipe is in communication with each water inlet and outlet connecting port 242, and the dispersed interfaces are integrated into an integrated water distribution pipeline through a main pipeline, thereby simplifying the water system layout of the entire device; ultimately realizing that all water inlet and outlet connecting ports 242 share one water inlet and outlet pipe, so that the entire ice making device only needs one external interface to complete all water inlet and outlet operations, which not only simplifies the installation work of the external pipeline, reduces the number of joints and potential water leakage risk, but also reduces the material cost and installation space requirement.

[0099] It can be understood that, as shown in Figures 2 to 3 The ice outlet is arranged at the top of the outer shell 40, and the position of the ice outlet corresponds to the position of the opening of the bracket 215, so as to facilitate the taking out of the water box assembly 20.

[0100] It can be understood that, as shown in Figures 18 to 22As shown, the ice maker further comprises a cuboid ice making device, which comprises a support seat 410, a spray evaporator 420, a spraying member 430 and a partition plate 440. The spray evaporator 420 is arranged at the upper portion of the support seat 410, the inside of the spray evaporator 420 is provided with a plurality of ice making cavities 421, and the bottom of the spray evaporator 420 is provided with a plurality of ice outlet ports 422 corresponding to the ice making cavities 421. The spraying member 430 is arranged in the inside of the support seat 410, and is adapted to spray water into the inside of the ice making cavities 421 through the ice outlet ports 422. The spray evaporator 420 is adapted to freeze the water in the ice making cavities 421 into ice. The partition plate 440 is arranged at at least one ice outlet port 422, and the thermal conductivity of the partition plate 440 is less than that of the spray evaporator 420.

[0101] The cuboid ice making device provided by the application sets the partition plate 440 made of thermal insulation material between adjacent ice outlet ports 422. Since the thermal conductivity of the partition plate 440 is less than that of the spray evaporator 420, the water in contact with the partition plate 440 is difficult to reach the freezing point due to the blocked heat transfer, thereby remaining in a liquid state and flowing downward due to gravity, and finally flowing into the water circulation system for repeated use. The partition plate 440 establishes a static heat barrier between adjacent ice making areas, effectively avoiding the "ice bridge" adhesion phenomenon during ice formation and growth, ensuring that each ice block can be independently and completely formed without any subsequent mechanical separation treatment, greatly improving the convenience of ice outlet and the completeness of ice block appearance. At the same time, since the present application adopts a top-down spraying method for ice making, the water flow is uniformly sprayed on the inner surface of the low-temperature ice making cavity 421 by the spraying member 430. In this process, the water body is always in a continuous flowing state. This dynamic freezing process makes it difficult for air and small impurities in the water to be "locked" in the ice crystal structure due to water agitation, but will be carried away with the un-frozen water flow, ensuring that the final ice block has a dense internal structure without air bubble inclusion, thereby obtaining high-quality ice blocks with crystal clear and transparent appearance.

[0102] It can be understood that the ice making cavity 421 is a cuboid, the ice outlet 422 is a rectangle, and therefore the ice cubes made are square ice with uniform shape and sharp corners. The spray evaporator 420 is designed as a compact cuboid, and six independent ice making cavities 421 are integrated inside the spray evaporator 420. At the same time, six ice outlets 422 are provided at the bottom of the spray evaporator 420. The six ice outlets 422 are arranged in an array of two rows and three columns. This highly integrated matrix layout enables the device to simultaneously produce multiple ice cubes in a very limited physical space, greatly improving the number of ice cubes produced per unit time and the overall work efficiency. To further ensure the uniformity of product quality, the size of each ice outlet 422 is designed to be exactly the same, which ensures that each square ice made from different cavities has the same specifications, meeting the requirements of ice cube standardization and quantification in commercial applications. By independently providing a rectangular frame-shaped partition 440 at each ice outlet 422, the frame structure not only physically isolates each ice outlet 422, but more importantly, forms an effective heat barrier between adjacent ice blocks being formed, fundamentally eliminating the phenomenon of "ice bridge" adhesion between ice blocks due to cold spread, ensuring that all ice blocks can be smoothly detached in the form of independent and complete individuals.

[0103] It can be understood that the multiple independent partitions 440 are integrated into a complete partition frame 441 through an integrated molding process, ensuring that the relative positions of the partitions 440 are fixed, so that precise alignment with the ice outlet 422 array at the bottom of the spray evaporator 420 can be achieved during installation, without the need for tedious adjustment of individual partitions 440, improving assembly efficiency. At the same time, the partition frame 441 is designed to be detachably connected with the spray evaporator 420, simplifying the cleaning and maintenance of the equipment in the later stage. Users or maintenance personnel can easily remove the entire partition frame 441, thereby obtaining access to the partition frame 441 itself and the areas such as the surface of the spray evaporator 420, the inner wall of the ice outlet 422, which are shielded by the partition frame 441, for thorough cleaning without dead angles, effectively removing scale or biofilm that may accumulate during long-term use, and ensuring the hygiene and safety of ice making.

[0104] It can be understood that one side of the support seat 410 is provided with an ice outlet, which provides a unified discharge channel for all the ice blocks made, facilitating efficient docking with the ice storage box or conveying device below. The plurality of shielding pieces 442 are arranged below the side of the baffle frame 441 close to the ice outlet, and are arranged along the length direction of the spray evaporator 420. These shielding pieces 442 form a barrier that effectively intercepts and guides the water flow that may directly fly towards the ice outlet when the bottom spray piece 430 sprays water upward, so that the water falls back to the upper surface of the spray piece 430, avoiding waste of water resources and ensuring dryness and cleanliness of the outside of the ice maker and the ice outlet channel. At the same time, the shielding pieces 442 can also prevent water from splashing to the ice outlet and forming ice on the edge of the ice outlet, ensuring that the ice outlet channel always remains unobstructed, and ensuring that the ice blocks can smoothly slide out when they fall off without being blocked.

[0105] It can be understood that the inside of the spray piece 430 has a flow collection channel 431, the spray piece 430 is provided with a water inlet and a plurality of nozzle mechanisms, the water inlet is suitable for supplying water to the flow collection channel 431, and the nozzle mechanisms are suitable for spraying water into the inside of the ice making cavity 421. The water inlet and the plurality of nozzle mechanisms are in communication with the flow collection channel 431. In this way, the water flow from the water inlet is collected and stabilized in a centralized cavity, ensuring that the water flow has reached a stable pressure state before being distributed to each nozzle mechanism, and ensuring that each nozzle mechanism can obtain nearly the same amount of water supply. The bottom of the spray piece 430 is provided with a support piece to space the bottom of the spray piece 430 from the bottom of the support seat 410, thereby forming a drainage channel 433 between the bottom of the spray piece 430 and the bottom of the support seat 410. Without the need for additional complex drainage pipes, the internal space layout is effectively optimized and the manufacturing cost is reduced. The bottom of the support seat 410 is provided with a drainage opening 434 in communication with the drainage channel 433, and the drainage opening 434 is a rectangular opening.

[0106] In operation, water first enters the flow collection channel 431 through the water inlet, and is then distributed to each nozzle mechanism through the flow collection channel 431, and is then sprayed upward into the ice making cavity 421 above through each nozzle mechanism. The water that has not frozen into ice flows back to the surface of the spray piece 430 under the action of gravity, and then collects and flows into the drainage channel 433. Finally, the water flows out through the drainage opening 434 in the bottom of the support seat 410 that is in communication with the drainage channel 433. After the water flows out from the drainage opening 434, it flows back to the cold water tank through the pipeline under the action of gravity for recycling.

[0107] It can be understood that the upper surface of the spraying member 430 is arranged towards the ice outlet and is inclined downward. Arranging the upper surface of the spraying member 430 towards the ice outlet and inclined downward has the following two advantages: first, during the ice making process, water droplets flowing from the ice making cavity 421 but not frozen will naturally collect and be guided into the drainage channel 433 along the inclined surface, not only effectively preventing water from accumulating on the surface of the spraying member 430, but also improving the efficiency of the entire water circulation system; second, when the ice making process is completed and enters the ice removal stage, the ice blocks falling from the spraying evaporator 420 can smoothly slide down along the inclined surface and be accurately guided to the only ice outlet, and finally reliably slide into the ice storage bin below, avoiding the accumulation and blockage of ice blocks inside the machine body, and ensuring the smooth progress of the continuous ice making process.

[0108] It can be understood that the nozzle mechanism in the embodiment is provided with three groups, of course, the number of nozzle mechanisms is not limited thereto, and is determined according to the number of ice making cavities 421 and the arrangement mode of the ice making cavities 421. The three groups of nozzle mechanisms are arranged on the upper surface of the spraying member 430 along the length direction of the spraying evaporator 420, each group of nozzle mechanisms includes two nozzles 435, the nozzles 435 in the same group are arranged along the width direction of the spraying evaporator 420, and the nozzles 435 are arranged one-to-one with the ice making cavities 421. This point-to-point spraying mode ensures that each ice making cavity 421 can obtain an independent water supply source, fundamentally ensuring that the amount of water received by all ice blocks during the molding process is equal and stable, which not only greatly improves the utilization efficiency of water resources, but also ensures that the size, weight and shape of the produced ice blocks are consistent.

[0109] It can be understood that a plurality of guide grooves 436 are arranged between adjacent two groups of nozzle mechanisms, the plurality of guide grooves 436 are arranged at intervals along the length direction of the spraying evaporator 420, and a guide area is formed on the upper surface of the spraying piece 430, which can effectively guide the backflow water in the length range of the spraying evaporator 420 and prevent local water accumulation; the adjacent two guide grooves 436 are parallel to each other, and the guide grooves 436 extend along the width direction of the spraying evaporator 420, that is, extend along the inclined direction of the upper surface of the spraying piece 430, so that the backflow water can flow smoothly and quickly into the guide grooves 436 along the inclined surface and be drained away, greatly improving the drainage efficiency and reducing the residence time of water on the surface of the spraying piece 430. The upper end and the lower end of the guide groove 436 with a relatively long length are both in communication with the drainage channel 433, and the upper end and the lower end of the guide groove 436 with a relatively short length are both in communication with the drainage channel 433. When the water backflowing in the ice making cavity 421 flows to the upper surface of the spraying piece 430, the water can be guided by the guide grooves 436 to flow into the drainage channel 433, effectively avoiding the intersection or collision of the backflow water and the water flow normally sprayed from the nozzle 435, ensuring that the water flow sprayed into the ice making cavity 421 is not disturbed and the flow is stable, thereby ensuring the uniformity and integrity of ice block formation, and finally improving the ice making efficiency and ice block quality.

[0110] It can be understood that the spraying piece 430 is detachably connected with the support seat 410, so as to facilitate the installation and disassembly of the spraying piece 430, and thereby facilitate the cleaning and maintenance of the spraying piece 430.

[0111] It can be understood that the cooling medium flow channel 423 is arranged inside the spraying evaporator 420, and the cooling medium flow channel 423 and the ice making cavity 421 are both arranged inside the spraying evaporator 420, which shortens the cold quantity transmission path and improves the overall heat exchange efficiency. The cooling medium flow channel 423 is located above the ice making cavity 421, so that the cold quantity can uniformly cover the entire ice making cavity 421 from top to bottom, forming an ideal counterflow heat exchange with the water flow sprayed from below, and ensuring that the refrigeration energy is most effectively utilized in the ice making process. The side wall of the spraying evaporator 420 is provided with a cooling medium inlet 424 and a cooling medium outlet 425 in communication with the cooling medium flow channel 423. During ice making, the cooling medium enters the cooling medium flow channel 423 through the cooling medium inlet 424, and performs efficient heat exchange with the water in the ice making cavity 421 in the cooling medium flow channel 423 through the inner wall of the spraying evaporator 420, which can rapidly reduce the temperature of the inner surface of the ice making cavity 421 to below the freezing point, so that the water sprayed thereon is quickly frozen into ice blocks in the ice making cavity 421, thereby significantly shortening the time required for single ice making and effectively improving the ice production per unit time. After heat exchange, the cooling medium that has absorbed heat and been gasified rises in temperature and flows out through the cooling medium outlet 425 to enter the condenser for heat dissipation and liquefaction, thereby forming a complete and sustainable refrigeration cycle.

[0112] It can be understood that the cooling medium flow channel 423 includes two groups of heat exchange flow channels. By dividing the complete flow channel into two groups, the flow path of the cooling medium can be more flexibly planned, and overall coverage of the surface of the spray evaporator 420 can be facilitated. The two groups of heat exchange flow channels are arranged in the width direction of the spray evaporator 420, and each group of heat exchange flow channels includes a plurality of flow channel units 426. The plurality of flow channel units 426 in the same group are sequentially connected in the length direction of the spray evaporator 420. The flow channel unit 426 is in a U shape. In one group of heat exchange flow channels, the first flow channel unit 426 is connected with the cooling medium inlet 424, and the last flow channel unit 426 is connected with the first flow channel unit 426 in the other group of heat exchange flow channels. In the other group of heat exchange flow channels, the last flow channel unit 426 is connected with the cooling medium outlet 425. This series connection mode constructs a complete, super-long "S" shape or serpentine flow channel that penetrates through the core area of the spray evaporator 420, ensuring that the low-temperature cooling medium entering the spray evaporator 420 can flow and absorb heat sufficiently, and maximizing the use of the cold carried by the cooling medium. By using a plurality of U-shaped flow channel units 426 connected in series, the effective flow path and heat exchange area of the cooling medium in the cooling medium flow channel 423 are increased, ensuring that the cooling medium and the spray evaporator 420 can exchange heat sufficiently and efficiently, thereby significantly improving the heat exchange efficiency and the overall refrigeration effect of the spray evaporator 420, ultimately resulting in faster ice-making speed and lower energy consumption.

[0113] It can be understood that the ice maker further includes a compressor, a refrigerant solenoid valve, a condenser, a drying filter, and a capillary tube. The outlet of the compressor is connected with the inlet of the condenser and the first interface of the refrigerant solenoid valve. The outlet of the condenser is connected with the inlet of the drying filter. The spray evaporator 420 and the first evaporator can be connected in series or in parallel.

[0114] When the spray evaporator 420 and the first evaporator are connected in series, the inlet of the capillary tube is connected with the outlet of the drying filter. The outlet of the capillary tube and the second interface of the refrigerant solenoid valve are both connected with the cooling medium inlet 424 of the spray evaporator 420. The cooling medium outlet 425 of the spray evaporator 420 is connected with the medium inlet 14 of the first evaporator. The medium outlet 15 of the first evaporator is connected with the inlet of the compressor.

[0115] When the spray evaporator 420 is connected in parallel with the first evaporator, the ice maker further comprises a three-way reversing valve, and the capillary tube has two, an inlet of the three-way reversing valve is communicated with an outlet of the dry filter, one outlet of the three-way reversing valve is communicated with the cooling medium inlet 424 of the spray evaporator 420 through one capillary tube, the other outlet of the three-way reversing valve is communicated with the medium inlet 14 of the first evaporator through the other capillary tube, the second interface of the refrigerant solenoid valve is communicated with the cooling medium inlet 424 of the spray evaporator 420 and the medium inlet 14 of the first evaporator, and the cooling medium outlet 425 of the spray evaporator 420 and the medium outlet 15 of the first evaporator are both communicated with the inlet of the compressor.

[0116] The spray evaporator 420 and the first evaporator not only play a freezing role in the ice making process, but also can play a role of heating and deicing. In the ice making process, the refrigerant solenoid valve is in a closed state, and the spray evaporator 420 and the first evaporator are both used for refrigeration to freeze the water in the corresponding ice making cavity into ice blocks; in the deicing process, the refrigerant solenoid valve is in an open state, the high-temperature and high-pressure medium output by the compressor directly enters the inside of the spray evaporator 420 and the first evaporator, and the temperature of the spray evaporator 420 and the first evaporator is increased to melt the surface of the ice block, so that the ice block is separated from the spray evaporator 420 or the first evaporator, and deicing is realized.

[0117] According to the second aspect of the present application, an ice making method is provided, which is based on the ice maker of any one of the above-mentioned embodiments. The ice making method comprises: In step S100, the water pump is controlled to pump the ice making water into the water inlet cavity 211; In step S200, the disturbance component 30 is controlled to drive the ice making water in the water inlet cavity 211 to flow, so that the ice making water in the water inlet cavity 211 and the ice making water in the first ice making cavity 221 flow with each other; In step S300, the first evaporator assembly 10 is controlled to freeze the ice making water in the first ice making cavity 221 into ice blocks.

[0118] According to the ice making method of the embodiment of the present application, the disturbance component 30 is used to drive the ice making water in the water inlet cavity 211 to flow, so that the ice making water in the water inlet cavity 211 and the ice making water in the first ice making cavity 221 flow with each other. In the process of water freezing into ice, the gas and impurities in the water are taken away by the continuously flowing liquid water, and will not be sealed in the ice crystals, finally ensuring that the ice blocks produced are bubble-free and crystal clear, and significantly improving the quality of the ice blocks.

[0119] It can be understood that the ice maker further comprises a drain valve communicated with the water inlet and outlet 212; and after the step of controlling the first evaporator assembly 10 to freeze the ice making water in the first ice making cavity 221 into ice blocks, the ice making method further comprises: Step S400, control the drain valve to open to drain the remaining ice-making water in the water inlet cavity 211 through the upper water inlet / outlet port 212.

[0120] Since the temperature of the remaining ice-making water in the water inlet cavity 211 is low, before pumping the ice-melting water, the low-temperature remaining ice-making water is drained in advance by controlling the drain valve to open, which can effectively avoid the mixing of the low-temperature ice-making water and the subsequent high-temperature ice-melting water. Thus, the ice-melting water entering the water inlet cavity 211 can be maintained at a high temperature level, and the ice in the water inlet cavity 211 can be melted more quickly and efficiently by using the high heat, which provides favorable conditions for the subsequent ice removal step and significantly improves the ice-melting efficiency of the entire ice-making cycle.

[0121] It can be understood that after the step of controlling the drain valve to open to drain the remaining ice-making water in the first ice-making cavity 221 through the upper water inlet / outlet port 212, the method further comprises: Step S400, control the water pump to pump ice-melting water into the water inlet cavity 211 to melt the ice in the water inlet cavity 211.

[0122] The temperature of the ice-melting water when injected into the first ice-making cavity 221 is higher than the temperature of the ice-making water when injected into the first ice-making cavity 221. By using ice-melting water with a higher temperature than ice-making water, the heat transfer effect is enhanced by the large temperature difference between the two, which can quickly transfer heat to the ice and effectively speed up the ice-melting speed, shortening the ice removal time of the ice-making cycle. The ice-melting water can be normal temperature water, or in order to pursue higher efficiency, a heater is added between the water pump and the water inlet cavity 211 to actively heat the ice-melting water. This design ensures that the ice-melting water has a high temperature when entering the water inlet cavity 211, thereby breaking the dependence on the ambient temperature and making the ice-melting process more stable, efficient and controllable. When the high-temperature ice-melting water is pumped into the water inlet cavity 211, it first melts the ice remaining in the water inlet cavity 211 and the ice in the turbulence hole 222 connecting the first ice-making cavity 221 and the water inlet cavity 211, which can accurately melt the key part connecting the finished ice block and the water box assembly 20 (inner shell 220), greatly improving the success rate and reliability of ice removal.

[0123] It can be understood that after the step of controlling the water pump to pump ice-melting water into the water inlet cavity 211 to melt the ice in the water inlet cavity 211, the method further comprises: Step S500, control the first evaporator assembly 10 to heat the side of the ice block close to the first evaporator assembly 10 to separate the ice block from the first evaporator assembly 10.

[0124] Although the ice block close to the inner shell 220 has been melted by the ice-melting water in the above steps, the problem of adhesion between the ice block and the inner shell 220 has been solved, but the ice block is still connected with the first evaporator assembly 10, which causes the ice block to be unable to be completely removed. Therefore, the ice block close to the first evaporator assembly 10 also needs to be deiced. Specifically, by controlling the refrigerant electromagnetic valve in the refrigeration system to be opened, the high-temperature and high-pressure gaseous refrigerant discharged by the compressor is directly introduced into the internal flow channel of the first evaporator assembly 10, which can quickly and directly use the high-temperature medium generated by the system itself as a heat source, without the need to add additional heating components and energy consumption, thereby realizing efficient and energy-saving heat transfer. When the high-temperature refrigerant flows through the first evaporator, the surface of the ice block in contact with the high-temperature refrigerant will rapidly increase in temperature, and only a very thin layer of ice on the contact surface will be melted into a layer of water film, thereby ensuring the integrity and low-temperature state of the main body of the ice block to the greatest extent and avoiding the quality of the ice block from being reduced due to excessive melting.

[0125] It can be understood that after the step of controlling the water pump to pump the ice-melting water into the water inlet cavity 211 to melt the ice block in the water inlet cavity 211, the following steps are further included: Step S410, control the drain valve to be opened to discharge the ice-melting water in the water inlet cavity 211 through the upper water inlet and outlet port 212 and the lower water inlet and outlet port 212.

[0126] After the ice block in the water inlet cavity 211 is melted, the residual ice in the lower water inlet and outlet port 212 is also melted, thereby ensuring that the lower water inlet and outlet port 212 returns to the open state. When the drain valve is controlled to be opened, the ice-melting water in the water inlet cavity 211 that has completed the ice-melting task can be simultaneously discharged through the upper water inlet and outlet port 212 and the lower water inlet and outlet port 212. The residual water in the cavity can be completely drained by means of gravity by using the lower water inlet and outlet port 212 located at the lowest point, thereby effectively avoiding the possible health problems caused by water accumulation.

[0127] It should be noted that the step S410 is executed after the step S400 and before the step S500.

[0128] It can be understood that the disturbance component 30 includes a driving mechanism 310 and a disturbance mechanism 320, the driving mechanism 310 is arranged outside the water inlet cavity 211, the disturbance mechanism 320 is arranged in the water inlet cavity 211, and the driving mechanism 310 is connected with the disturbance mechanism 320.

[0129] Specifically, the driving mechanism 310 and the disturbing mechanism 320 can be directly connected or connected by magnetic attraction. When the driving mechanism 310 and the disturbing mechanism 320 are directly connected, the water box body 210 is provided with a connecting hole, a connecting shaft of the driving mechanism 310 penetrates through the connecting hole and is connected with the disturbing mechanism 320, the driving mechanism 310 is adapted to drive the disturbing mechanism 320 to move, and the disturbing mechanism 320 is adapted to drive the water in the water inlet cavity 211 to flow. When the driving mechanism 310 and the disturbing mechanism 320 are connected by magnetic attraction, the disturbing part 30 further comprises a first magnetic attraction mechanism 330 and a second magnetic attraction mechanism 340, the driving mechanism 310 and the first magnetic attraction mechanism 330 are both arranged outside the water box assembly 20, the driving mechanism 310 is connected with the first magnetic attraction mechanism 330, the disturbing mechanism 320 and the second magnetic attraction mechanism 340 are both arranged in the water inlet cavity 211, and the disturbing mechanism 320 is connected with the second magnetic attraction mechanism 340, the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340 are magnetically attracted and matched.

[0130] It can be understood that the step of controlling the disturbing part 30 to drive the ice-making water in the water inlet cavity 211 to flow comprises: The driving mechanism 310 drives the disturbing mechanism 320 to rotate forward or reverse, until the ice-making water in the first ice-making cavity 221 is frozen into ice blocks.

[0131] It can be understood that the step of controlling the disturbing part 30 to drive the ice-making water in the water inlet cavity 211 to flow comprises: Step S210, controlling the driving mechanism 310 to drive the disturbing mechanism 320 to rotate forward for a first predetermined time; Step S220, controlling the driving mechanism 310 to stop for a second predetermined time; Step S230, controlling the driving mechanism 310 to drive the disturbing mechanism 320 to rotate reverse for a first predetermined time; Step S240, sequentially repeating the above steps.

[0132] By making the driving mechanism 310 drive the disturbing mechanism 320 to rotate forward for a first predetermined time and stop for a second predetermined time, and then making the driving mechanism 310 drive the disturbing mechanism 320 to rotate reverse for a first predetermined time, a periodic disturbance is formed to change the water flow direction constantly, simulating the "oscillating cleaning" effect, so that the bubbles in the first ice-making cavity 221 and the water inlet cavity 211 are difficult to stay.

[0133] By driving the driving mechanism 310 to drive the disturbance mechanism 320 to rotate forward for a first predetermined time, a strong one-way water flow can be generated, thereby effectively flushing the inner walls of the first ice-making cavity 221 and the water inlet cavity 211 and the surface of the ice layer being formed, and forcibly stripping the bubbles that have already attached or are about to attach; then stopping for a second predetermined time, this short period of stillness is not completely still, but uses the inertia of the water flow to produce reverberation and turbulence, which not only disrupts the regular attachment trend of the bubbles, but also provides a time window for the tiny bubbles suspended in the water body to float or gather; then driving the driving mechanism 310 to drive the disturbance mechanism 320 to rotate reversely for a first predetermined time, a strong water flow in the opposite direction is generated, which performs secondary reverse flushing on the bubbles that have not been effectively removed or have reassembled during the still period. Such a positive and negative rotation plus the pause in between forms a highly efficient periodic disturbance, which makes the water flow direction in the cavity change constantly, simulates a high-efficiency "oscillating cleaning" effect, and makes it extremely difficult for the bubbles to stay in the solid-liquid interface or remain stationary in the water body, thereby being effectively removed from the ice-making area, and finally obtaining ice blocks with high transparency and no bubbles.

[0134] It can be understood that after the step of sequentially repeating the above steps, the method further comprises: Step S250, controlling the driving mechanism 310 to drive the disturbance mechanism 320 to rotate forward for a second predetermined time, wherein the second predetermined time is less than the first predetermined time; Step S260, controlling the driving mechanism 310 to drive the disturbance mechanism 320 to rotate reversely for a second predetermined time; Step S270, sequentially repeating the above steps until the ice-making water in the first ice-making cavity 221 is frozen into ice blocks.

[0135] By driving the driving mechanism 310 to drive the disturbance mechanism 320 to rotate forward for a short second predetermined time, this rapid and short agitation can generate a transient water flow impact, which can disturb the solidifying ice-water interface, thereby breaking the critical stable state of the bubbles staying there; and then driving the disturbance mechanism 320 to rotate reversely for the same second predetermined time, this rapid reverse action generates a reverse transient impact, which can again strip the bubbles that have not been timely driven away or pushed to other corners by the previous action. Since the second predetermined time is significantly smaller than the first predetermined time for realizing water flow circulation, this forward and reverse rapid switching forms a high-frequency commutation rotating mode. This mode excites continuous micro oscillation and turbulence in the water body near the ice block surface, and its effect is like high-frequency "scraping" on the surface of the ice layer that is about to freeze, so that the micro bubbles in the water are pushed away by the continuous dynamic water flow before being "captured" by ice crystals, greatly reducing the probability of bubbles being solidified at the solid-liquid interface, thereby significantly improving the transparency and purity of the final product of ice block.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
