[0206] When making ice, water needs to be poured into the ice mold, and then the mold is cooled to freeze the water in the mold into ice. After the water freezes into ice, the ice mold is opened. The existing ice mold opening process has a low degree of automation.

[0207] At the same time, the existing ice-making mold has a problem of slow energy transfer during the ice-making process. When the energy transfer is slow, it takes a long time to freeze water into ice during the ice-making process. After the ice-making is completed, it also takes a long time to demould the ice.

[0208] 1 to 7 , an ice making machine includes a frame 1 , an upper ice mold 2 , a lower ice mold 3 , a refrigeration unit 4 , a water supply unit 5 , a drive unit 6 , an ice melting unit 8 and an ice dropping unit 9 .

[0209] The frame 1 is a gantry structure, and the upper ice mold 2, the lower ice mold 3 and the ice drop unit 9 are arranged in the gantry structure.

[0210] The driving unit 6 includes a motor device 61 and a lifting mechanism 62 . The motor device 61 drives the lifting mechanism 62 to drive the lower ice mold 3 to slide up and down, thereby achieving movable splicing or separation with the upper ice mold 2 .

[0211] The upper ice mold 2 has at least one upper mold cavity 21, and the lower ice mold 3 has at least one lower mold cavity 31. The upper ice mold 2 and the lower ice mold 3 are joined so that the upper mold cavity 21 and the lower mold cavity 31 are connected to form an ice-making mold cavity 7 for ice condensation. The upper mold cavity 21 and the lower mold cavity 31 can be provided with four ice-making mold cavities 7 arranged in a square and evenly distributed on the upper mold cavity 21 and the lower mold cavity 31, and the ice-making mold cavity 7 formed by each upper mold cavity 21 and the lower mold cavity 31 is identical in structure.

[0212] The refrigeration unit 4 includes an evaporator tube 41, which is wound around the upper ice mold 2 and can be used to cool the upper ice mold 2. The refrigeration unit 4 can also operate in reverse, heating the upper ice. This is prior art and will not be further elaborated upon here. In one embodiment, the evaporator tube 41 is designed in a circular shape, with the air inlet and return port of the evaporator tube 41 cleverly located on the same side. This design increases the contact area between the evaporator tube 41 and the upper ice mold 2, significantly improving the evaporator's cooling efficiency. Furthermore, it significantly improves the uniformity of the cooling effect, ensuring uniform cooling and heating temperatures within each ice mold cavity 7. This ensures that the weight of the ice balls produced by each ice mold cavity 7 is nearly uniform.

[0213] The water supply unit 5 and the ice melting unit 8 are arranged on the lower ice mold 3 .

[0214] The water supply unit 5 includes a nozzle 51, a water supply pipe 52, and a return water structure. The nozzle 51 is installed on the lower ice mold 3, and the nozzle 511 of the nozzle 51 is connected to the ice mold cavity 7. The water supply pipe 52 is connected to the water source in the water tank component (not shown in the figure) to supply water to the nozzle 51. The nozzle 511 can spray water into the ice mold cavity 7 for ice making. The return water mechanism 53 includes a return water box 54, a return water channel 55, and a water outlet channel 56. There are more than one return water channel 55. The return water box 54 is arranged at the bottom of the lower ice mold 3 and is connected to the ice mold cavity 7 through the return water channel 55. When making ice, some water in the ice mold cavity 7 that fails to freeze quickly flows back to the return water box 54 through the return water channel 55 and is collected. It then flows back to the water tank component (not shown in the figure) through the water outlet channel 56 for recycling, effectively saving water. Because water may leak through the joint gap between the upper and lower ice molds when spraying water into the ice mold cavity 7, a water receiving trough is provided on the periphery of the lower ice mold to collect water leaking from the joint gap. As shown in Figure 9, to further enhance the ice-making effect, the nozzle 511 has a spiral water outlet. Under the guidance of the spiral water outlet, water can be sprayed at multiple angles within the ice mold cavity 7, thereby spraying the ice mold cavity 7 more evenly, resulting in a more uniform ice layer on the ice mold cavity 7. Furthermore, the top of the upper mold cavity 21 is provided with one or more air vents 22. When water is sprayed onto the wall of the ice mold cavity 7 and condenses into ice, the air between the water and the wall of the ice mold 7 can be discharged through the air vents 22 during the condensation process. This facilitates the expulsion of air, resulting in a more compact and transparent ice cube with a smooth surface without bumps.

[0215] The ice-melting unit 8 includes a heating device 81 arranged on the lower ice mold 3, and the heating device 81 heats the wall surface of the lower mold cavity 31. In one embodiment, the heating device 81 is a PTC heating plate arranged in contact with the bottom of the lower ice mold 3. As shown in FIG8 , the bottom of the lower ice mold 3 is provided with a through hole penetrating the lower mold cavity 31, and the heating plate is provided with a water seat 82 which is sealed and inserted into the through hole, and the top surface of the water seat 82 is smoothly connected with the wall surface of the lower mold cavity 31. The water seat 82 is provided with a water inlet channel 57 and a water return channel 55. The nozzle 511 of the nozzle 51 is inserted into the water inlet channel 57 to communicate with the ice-making mold cavity 7. The arrangement and installation of the heating device 81 can simultaneously realize the communication arrangement of the water supply unit 5 and the ice-making mold cavity 7, integrate the ice-melting unit 8 and the water supply unit 5 located on the lower ice mold 3, and make the structure on the lower ice mold 3 more compact. The return water box 54 is fitted and covered under the water seat 82, and the water supply pipe 52 passes through the bottom wall of the return water box 54 and is connected to the nozzle 51. The heating device 81 can also be used to dry and disinfect the return water box 54 and the water supply pipe 52 at high temperature, making it difficult for bacteria and scale to grow.

[0216] The lifting mechanism 62 of the drive unit 6 is a vertically arranged screw device, including a screw 63, a guide column 64 arranged parallel to the screw 63, and a screw seat 65 connected to the screw 63. The end of the screw 63 is connected to a transmission wheel 66 which is transmission-connected to the motor device 61. The lower ice mold 3 is connected to the screw seat 65 and is mounted on the guide column 63. The transmission of the screw device is stable and precise, which is conducive to controlling the precise combination and rapid separation of the lower ice mold 3 and the upper ice mold 2. In order to make the lifting movement of the lower ice mold 3 more stable, the lifting mechanism 62 has two parts arranged on opposite sides of the frame 1, and the two sides of the lower ice mold 3 are connected to the lifting mechanism 62; the motor device 61 is installed on the side of the frame 1 and is connected to the driving wheel 67, and the transmission wheels 66 of the two lifting mechanisms 62 and the driving wheel 67 of the motor device 61 are arranged on the top of the frame 1. A transmission belt 68 is installed between the driving wheel 67 and the two transmission wheels 66, which are driven by the driving wheel 67 to realize the synchronous rotation of the two transmission wheels 66. In this embodiment, the driving wheel 67 and the two transmission wheels 66 are installed in the same transmission belt 68, and the belt is tensioned into an isosceles triangle.

[0217] The ice drop unit 9 includes an ice guide mechanism 91 and a driven mechanism 92. The driven mechanism 92 is drivably connected to the lower ice mold 3. The lower ice mold 3 slides downward and simultaneously drives the ice guide mechanism 91 to rotate and flip into the space between the upper ice mold 2 and the lower ice mold 3, located below the upper mold cavity 21, to catch ice cubes that fall out of the upper mold cavity 21. The ice guide mechanism 91 includes an upper ice guide plate 93 and a lower ice guide plate 94. The upper ice guide plate 93 has a rotating shaft 95 at its top end, which is rotatably connected to the upper portion of one side of the frame 1 and is connected to the gear 97. The lower ice guide plate 94 has a hinge shaft 98 at its bottom end, which is rotatably connected to the lower portion of the other side of the frame 1. The lower ice guide plate 94 has a gravity arm 99 extending toward the lower ice mold 3. The center of gravity of the gravity arm 99 is offset so that the inner side surface of the lower ice guide plate 94 continuously abuts against the lower ice mold 3. The driven mechanism 92 includes a rack 96 that moves up and down following the lower ice mold 3 and a gear 97 connected to the end of the rotating shaft 95 of the ice guide mechanism 91. The rack 96 drives the gear 97 to rotate to rotate the upper ice guide plate 93 into the frame 1 to between the upper ice mold 2 and the lower ice mold 3, and the center of gravity of the lower ice guide plate 94 leans against the lower ice mold 3. When the lower ice mold 3 descends, the lower ice guide plate 94 leans against the lower ice mold 3 and flips downward to rotate between the upper ice mold 2 and the lower ice mold 3 and engages with the end of the upper ice guide plate 93 to form a sloped ice guide plate, and an ice basket is placed at the end of the ice guide plate. The ice cubes that fall off the upper ice mold 2 fall onto the ice guide plate, slide along the slope, and fall into the ice basket. When the lower ice mold 3 rises again, the rack 96 drives the gear 97 to drive the upper ice guide plate 93 to flip out of the area between the upper ice mold 2 and the lower ice mold 3 and return to the upright state. At the same time, the lower ice mold 3 also lifts the lower ice guide plate 94 and rises out of between the upper ice mold 2 and the lower ice mold 3, so that the upper and lower ice molds can be engaged again.

[0218] In this embodiment, the upper mold cavity 21 and the lower mold cavity 31 are both hemispherical, and the spherical ice-making mold cavity 7 formed by connecting them is used to make ice balls. The following describes the ice-making method of the present application by making ice balls:

[0219] Step a: Start the driving unit 6, and drive the lifting mechanism 62 via the motor device 61 to slide the lower ice mold 3 upward to mate with the upper ice mold 2, and dock the lower mold cavity 31 with the upper mold cavity 21 to form a spherical ice mold cavity 7;

[0220] Step b: starting the refrigeration unit 4 to reduce the wall temperature of the ice-making mold cavity 7 to the freezing temperature;

[0221] Step c: Start the water supply unit 5 to spray water into the ice-making mold cavity 7 through the nozzle 51. The water contacts the cavity wall and forms a spherical ice layer.

[0222] Step d: continuously spraying water into the ice-making mold cavity 7 and adhering to the ice layer, so that the water flow condenses layer by layer on the ice layer until a complete ice ball is formed;

[0223] Step e: After the ice cube has completely solidified, the ice melting unit 8 is activated to heat the wall of the lower mold cavity 31, causing the surface of the ice ball in contact with the lower mold cavity 31 to initially melt, causing the ice cube to relatively separate from the lower mold cavity 31. The driving mechanism is then activated again to drive the lower ice mold 3 to slide downward and separate from the upper ice mold 2, and the ice ball adheres to the upper mold cavity 21.

[0224] Step f: The lower ice mold 3 slides downward and simultaneously links with the ice drop unit 9. The lower ice mold 3 drives the ice guide mechanism 91 to rotate through the driven mechanism 92 and flips into the space between the upper ice mold 2 and the lower ice mold 3 and is located below the upper mold cavity 21.

[0225] In step g, the refrigeration unit 4 operates in reverse to generate heat, causing the surface of the ice cube in contact with the upper mold cavity 21 to initially melt, causing the ice cube to separate from the upper mold cavity 21 and fall. At this time, the ice guide mechanism 91 receives the ice cube and guides it to slide out of the frame 1 and fall into the ice basket.

[0226] The lower mold of the present application is separated and spliced ​​with the upper mold through a simple sliding lifting mechanism 62, which can effectively simplify the internal structure of the existing ice maker and reduce the lifting movement without reserving too much movement space, solving the problem of the large size of the entire machine, allowing the ice maker to be smaller in size, reduce the space occupied, and thus be more suitable for use in the home.

[0227] In addition, the above-mentioned ice-making method is changed to rely on thermal energy for rapid ice defrosting. The ice cubes can be removed from their respective mold cavities by slightly heating the lower ice mold 3 and the upper ice mold 2 in turn, and the ice falling unit 9 catches the ice cubes that have escaped and guides them to a designated location for storage and use. The ice defrosting method is efficient and simple, can effectively prevent the ice cubes from being damaged, and can save water resources, without the need to consume a large amount of water like the previous immersion defrosting solution.

[0228] The present application provides an ice making machine.

[0229] Please refer to Figures 10, 12, and 14. In one embodiment of the present application, the ice maker includes:

[0230] Rack 100a;

[0231] The mold assembly 200a includes a first mold 210a and a second mold 220a. The first mold 210a is fixed to the frame 100a and has at least one first mold cavity 213a. The second mold 220a is movably mounted on the frame 100a and has at least one second mold cavity 223a.

[0232] The driving assembly 300a is mounted on the frame 100a and is connected to the second mold 220a. The driving assembly 300a is capable of driving the second mold 220a to flip so that the second mold 220a has a first position of being closed relative to the first mold 210a and a second position of being open relative to the first mold 210a. When the driving assembly 300a drives the second mold 220a to flip so that the second mold 220a is in the first position, the second mold 220a is merged with the first mold 210a, and the first mold cavity 213a and the second mold cavity 220a are closed. 3a constitutes an ice-making cavity 230a, and the ice-making cavity 230a is used for making ice, and a first mold cavity 213a and a second mold cavity 223a are correspondingly arranged; when the number of the first mold cavity 213a and the second mold cavity 223a is set to one, the number of the ice-making cavity 230a is one; when the number of the first mold cavity 213a and the second mold cavity 223a is set to three, the number of the ice-making cavity 230a is also three; when ice making is completed, when the driving component 300a drives the second mold 220a to the second position, ice can be separated from the mold component 200a. In this embodiment, before making ice, the second mold 220a is first driven to flip by the driving assembly 300a, so that the second mold 220a flips to the first position. At this time, the second mold 220a is merged with the first mold 210a (see Figure 12), and the first mold cavity 213a and the second mold cavity 223a constitute an ice-making cavity 230a. After the ice-making cavity 230a is formed, water is injected into the ice-making cavity 230a, and then the mold assembly 200a is cooled by refrigerant or other means. By cooling the mold assembly 200a, the water in the ice-making cavity 230a is cooled, so that the water is frozen into ice. After the preset cooling time, the water in the ice-making cavity 230a is frozen into ice. When the water in the ice-making chamber 230a is completely frozen into ice, the driving assembly 300a drives the second mold 220a to flip, so that the second mold 210a moves to the second position. At this time, the second mold 220a and the first mold 210a are in an open state (see Figure 17). After opening, the ice body can be separated from the mold assembly 200a.

[0233] The technical solution of the present application uses a driving assembly 300a to drive the second mold 220a to flip; when ice making is required, the driving assembly 300a drives the second mold 220a to flip so that it is located at the first position. At this time, the second mold 220a is merged with the first mold 210a, and the first mold cavity 213a and the second mold cavity 223a form an ice-making cavity 230a. By injecting water into the ice-making cavity 230a and then cooling the mold assembly 200a, the temperature of the water in the ice-making cavity 230a is reduced, and the water is frozen into ice; when After ice making is completed, the driving component 300a drives the second mold 220a to flip, so that the first mold 210a moves to the second position. At this time, the mold opening of the mold component 200a is completed, and then the ice can be removed from the first mold cavity 213a or the second mold cavity 223a. In the present application, the driving component 300a drives the second mold 220a to flip to realize the merging and opening of the mold assembly 200a, which can effectively improve the degree of automation of the mold opening of the ice maker during the ice making process, thereby solving the technical problems existing in the prior art.

[0234] In one embodiment, referring to Figure 11, the second mold 220a and the first mold 210a are hinged by a rotating shaft 10a; wherein, a first through hole 215a is provided in the first mold 210a for the rotating shaft 10a to pass through, and a second through hole 226a is provided in the second mold 220a for the rotating shaft 10a to pass through; further, the second mold 220a includes a cover body 216a, the first through hole 215a is provided with the cover body 216a, and the cover body 216a is fixed to the frame 100a.

[0235] In one embodiment, referring to Figure 11, the driving assembly 300a includes a driving member, which is drivably connected to the second mold. Further, the driving member is configured as a driving motor 330a, and the driving motor 330a is drivably connected to the second mold 220a to enable the second mold 220a to flip around the rotating shaft 10a. In this embodiment, the rotating shaft 10a is drivably connected to the second mold 220a. Specifically, the rotating shaft 10a is key-connected to the second through hole 226a in the second mold 220a or, through a fixed arrangement, the rotating shaft 10a is clearance-fitted with the first through hole 215a in the first mold 210a. When the driving motor 330a drives the rotating shaft 10a to rotate, the rotating shaft 10a can drive the second mold 220a to flip.

[0236] In one embodiment, referring to Figure 11, the driving assembly 300a also includes a first spring 350a and a connecting arm 360a. The connecting arm 360a is fixedly arranged, specifically, the connecting arm 360a is fixed to the frame 100, one end of the first spring 350a is connected to the connecting arm 360a, and the other end is connected to the side of the second mold 220a away from the rotating shaft 10a. In this way, during the ice-removing process, the driving component 300a drives the second mold 220a to flip to the second position, and stretches the first spring 350a through the connecting arm 360a. At this time, the first spring 350a is deformed by the tension; when the ice-removing is completed, when the second mold 220a and the first mold 210a need to be merged, the second mold 220a can be rotated around the rotating axis 10a and merged with the first mold 210a through the restoring force of the first spring 350a. In this way, the driving component 300a does not need to drive the second mold 220a to merge with the first mold 210a, and the second mold 220a and the first mold 210a can be merged under the action of the first spring 350a.

[0237] However, the present design is not limited thereto. In other embodiments, the second mold 220a may also be hinged to the frame 100a via the rotating shaft 10a.

[0238] However, the present design is not limited to this. In other embodiments, the second mold 220a and the first mold 210a are connected by a connecting rod and a slider guide rail structure. Specifically, the guide rail in the connecting rod and the slider guide rail structure is fixedly arranged, which can be fixedly arranged on the first mold 210a or the frame 100a. The connecting rod in the connecting rod and the slider guide rail structure has one end hinged to the middle position of the second mold 220a and the other end hinged to the first mold 210a or the frame 110a. The slider in the connecting rod and the slider guide rail structure slides on the guide rail in its structure, and the slider is also hinged to the second mold. One end of 220a is hinged, and the driving member in the driving assembly is connected to the slider in the structure, driving the slider to move along the guide rail of the structure. As the slider approaches or moves away from the hinge between the connecting rod and the first mold 210a or the frame 110a, the second mold 220a can be flipped in two directions, so that when the second mold 220a is flipped in one direction, the second mold 220a can be merged with the first mold 110a; when flipped in the other direction, the second mold 220a can be separated from the first mold 110a, so that the mold assembly 200a completes the mold opening.

[0239] In one embodiment, referring to FIG. 14 , the first mold 210a is provided with a first flow channel 214a for circulating refrigerant. The first flow channel 214a includes multiple loops of flow channels 2141a that are sequentially connected in a direction away from the second mold 220a. Specifically, the multiple loops of flow channels 2141a are arranged around the first mold cavity 213a, that is, the first flow channel 214a is arranged around the first mold cavity 213a. In this embodiment, the first mold 210a can have different effects depending on the temperature of the refrigerant introduced into the first flow channel 214a. When the temperature of the refrigerant introduced is low, the refrigerant freezes the water in the ice-making cavity 230a. When the temperature of the refrigerant introduced is high, that is, high-temperature refrigerant, the high-temperature refrigerant can thaw the ice and the walls of the first mold cavity 213a.

[0240] In this embodiment, because the first flow channel 214a includes multiple loops of flow channels 2141a that connect sequentially in a direction away from the second mold 220a, the multiple loops of flow channels 2141a can increase the relative contact area between the first flow channel 214a and the first mold cavity 213a. When refrigerant is introduced into the first flow channel 214a, the increased relative contact area between the first flow channel 214a and the first mold cavity 213a allows the refrigerant's energy to be transferred more quickly to the ice-making cavity 230a, thereby rapidly cooling the ice-making cavity 230a and achieving rapid freezing of the water in the ice-making cavity 230a. Similarly, when ice needs to be thawed from the wall of the first mold cavity 213a, the first flow channel 214a can also achieve rapid thawing.

[0241] In one embodiment, for any circle flow channel 2141a in the middle, its connection point (not shown) with the adjacent circle flow channel 2141a close to the second mold 220a and its connection point with the adjacent circle flow channel 2141a away from the second mold 220a are respectively arranged on opposite sides of the circle flow channel 2141a. That is, after the refrigerant enters the first flow channel 214a, it first enters the flow channel 2141a of the upper layer, and then flows along the flow channel 2141a of the upper layer to the connection point. At this time, it enters the flow channel 2141a of the middle layer through the connection point, and then The refrigerant flows along the middle layer flow channel 2141a to the connecting point, and then flows into the lower layer flow channel 2141a through the connecting point between the middle layer flow channel 2141a and the lower layer flow channel 2141a. At this time, the flow direction of the refrigerant in the upper layer flow channel 2141a is opposite to the flow direction in the lower layer flow channel 2141a. This can prevent the refrigerant from directly entering the middle layer and the lower layer flow channels 2141a from the upper layer flow channel 2141a, and can increase the flow path of the refrigerant in the first flow channel 214a, thereby increasing the relative contact area between the refrigerant and the first mold cavity 213a.

[0242] In one embodiment, the first mold 210a can adopt the following structure, wherein the first mold 210a includes a first mold body 211a and a first mold cover 212a, the first mold body 211a and the first mold cover 212a are installed on the cover body 216a, the first mold cover 212a covers the first mold body 211a, the first mold cavity 213a is formed on the side of the first mold body 211a away from the first mold cover 212a, and the first flow channel 214a is formed between the first mold cover 212a and the first mold body 211a. Specifically, the first flow channel 214a is formed between the first mold cover 212a and the first mold body 211a so as to be arranged around the first mold body 211a, thereby achieving the purpose of surrounding the first mold cavity 213a, and the first flow channel 214a surrounds the first mold body 211a one or more circles, thereby achieving the first flow channel 214a surrounding the first cavity one or more circles. In this embodiment, the first mold cover 212a is configured as a special-shaped cover, and a groove structure (not shown) is formed in the first mold cover 212a. When the first mold cover 212a covers the first mold body 211a, the first flow channel 214a is formed outside the first mold body 211a. In this case, the first flow channel 214a is located between the first mold cover 212a and the first mold body 211a. At the same time, when the wall thickness of the first mold cavity 213a is uniform, the energy in the first flow channel 214a surrounding the outside of the first mold body 211a can be evenly transferred to the first mold cavity 213a through the first mold body 211a, thereby achieving more uniform freezing of the ice-making cavity 230a and more uniform thawing during the thawing process, resulting in a more complete ice body after thawing.

[0243] However, the present design is not limited to this. In other embodiments, the first mold 210a may also adopt other structures. For example, the first mold 210a may only include the first mold body 211a. In this case, the first flow channel 214a is formed on the outside of the first mold body 211a. Specifically, a pipeline (not shown) is fixed to the outside of the first mold body 211a, and the first flow channel 214a is set in the pipeline, wherein the pipeline can be set around the outside of the first mold body 211a in one or more circles.

[0244] In one embodiment, referring to Figures 26 to 28, the first mold 210a is embedded with a copper tube 217a, which is used for the circulation of refrigerant. The first mold cavity 213a is formed on the side of the first mold body 210a away from the copper tube 217a. By passing refrigerants of different temperatures into the copper tube 217a, the copper tube 217 transfers the energy of the refrigerant to the first mold 210a, and then transfers it to the first mold cavity 213a, thereby freezing the water in the ice-making cavity 230a, or thawing the ice body and the cavity wall of the first mold cavity 213a.

[0245] In one embodiment, referring to FIG16 , the second mold 220a is provided with a second flow channel 227a for the circulation of a thawing medium; when the temperature of the refrigerant introduced is high, the temperature of the refrigerant is high, i.e., high-temperature refrigerant, which can thaw the ice body and the cavity wall of the second mold cavity 223a.

[0246] Furthermore, when the second mold 220a is provided with a second flow channel 227a for circulating a thawing medium, the mold assembly 200a can adopt one of the following methods during the deicing process: during the deicing process, the thawing medium is introduced into the second flow channel 227a to thaw the produced ice body and the second mold 220a, and then the second mold 220a is driven to flip to the second position by the driving assembly 300a, and then a high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210a;

[0247] Alternatively, during the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214a to thaw the prepared ice body and the first mold 210a, and then the second mold 220a is flipped to the second position by the driving assembly 300a, and then a thawing medium is introduced into the second channel to thaw the ice body and the second mold 220a;

[0248] Alternatively, during the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214a, and a thawing medium is introduced into the second channel to thaw the prepared ice body and the first mold 210a and the second mold 220a, and then the second mold 220a is driven to flip to the second position by the driving component 300a.

[0249] In one embodiment, referring to FIG. 16 , the second flow channel 227a includes multiple flow channels connected sequentially in a direction away from the first mold 210a , and the multiple flow channels in the second flow channel 227a have similar or identical structures to the multiple flow channels in the first flow channel 214a .

[0250] In one embodiment, referring to FIG16 , the second mold 220a includes a second mold body 221a and a second mold cover 222a. The second mold cover 222a is disposed over the second mold body 221a. The second mold cavity 223a is formed on a side of the second mold body 221a facing away from the second mold cover 222a. The second flow channel 227a is disposed between the second mold body 221a and the second mold cover 222a. In this embodiment, the second mold cover 222a is configured as a special-shaped cover having a groove structure (not shown) formed therein. When the second mold cover 222a covers the second mold body 221a, the second flow channel 227a is formed outside the second mold body 221a. In this case, the second flow channel 227a is located between the second mold cover 222a and the second mold body 221a.

[0251] However, the present design is not limited to this. In other embodiments, the second mold 220a may also adopt other structures. For example, the second mold 220a may only include the second mold body 221a. In this case, the second flow channel 227a is formed on the outside of the second mold body 221a. Specifically, a pipeline (not shown) is fixed to the outside of the second mold body 221a, and the second flow channel 227a is set in the pipeline, wherein the pipeline can be arranged around the outside of the second mold body 221a in one or more circles.

[0252] In one embodiment, referring to FIG15 , the second mold 220 a is located below the first mold 210 a ;

[0253] The ice maker also includes a water storage tray 20a, which is installed on the second mold 220a. The water storage tray 20a is used to store the thawing medium so that the thawing medium can soak the second mold 220a. In this embodiment, the thawing medium can be a high-temperature refrigerant or high-temperature water. The thawing medium is passed into the water storage tray 20a. At this time, the thawing medium transfers heat energy through the second mold 220a to the second mold cavity 223a. Under the action of heat energy, the ice body and the inner wall of the second mold cavity 223a are melted to complete the thawing.

[0254] Furthermore, when the ice maker further includes a water storage tray 20a, the mold assembly 200a can adopt one of the following methods during the ice-de-icing process: during the ice-de-icing process, the thawing medium is introduced into the water storage tray 20a to thaw the produced ice body and the second mold 220a, and then the second mold 220a is driven to flip to the second position by the driving assembly 300a, and then a high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210a;

[0255] Alternatively, during the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214a, and a thawing medium is introduced into the water storage tray 20a, so that the prepared ice body and the first mold 210a and the second mold 220a are thawed, and then the second mold 220a is driven to flip to the second position by the driving component 300a.

[0256] In one embodiment, referring to Figures 13 and 14, the cavity wall of the second mold cavity 223a is set to be of equal or nearly equal thickness, and the ice maker also includes a heating element 500a covering the back side of the cavity wall of the second mold cavity 223a; in one embodiment, when the cavity wall of the second mold cavity 223a has the same thickness, the energy in the heating element 500a covering the back side of the cavity wall of the second mold cavity 223a can be evenly transferred to the second mold cavity 223a through the second mold body 221a, thereby achieving a more uniform freezing of the ice-making cavity 230a, or a more uniform thawing during the thawing process, so that the thawed ice body is more complete. In this embodiment, when the second mold 220a only includes the second mold body 221a, the back side of the cavity wall of the second mold cavity 223a is the outer surface of the second mold body 221a; further, when the ice body and the cavity wall of the second mold cavity 223a are thawed by the heating element 500a, the heating element 500a can be configured as a heating film, which generates heat through the heating element 500a and transfers the heat to the second mold cavity 223a through the second mold body 221a, so as to melt and thaw the ice body and the cavity wall of the second mold cavity 223a.

[0257] Furthermore, when the ice maker further includes a heating element 500a, the mold assembly 200a can adopt one of the following methods during the ice-de-icing process: during the ice-de-icing process, the heating element 500a generates heat to thaw the produced ice body and the second mold 220a, and then the driving assembly 300a drives the second mold 220a to flip to the second position, and then a high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210a;

[0258] Alternatively, during the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214a to thaw the prepared ice body and the first mold 210a. Then, the driving assembly 300a drives the second mold 220a to flip to the second position, and the heating element 500a generates heat to thaw the ice body and the second mold 220a.

[0259] Alternatively, during the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214a, and heat is generated by the heating element 500a to thaw the prepared ice body and the first mold 210a and the second mold 220a, and then the driving component 300a drives the second mold 220a to flip to the second position.

[0260] In one embodiment, referring to Figure 13, the heating element 500a includes a flexible body 510a covering the back side of the cavity wall of the second mold cavity 223a, and a heating element (not shown) embedded in the flexible body 510a. In this embodiment, by heating the heating element, the heat generated by the heating element is transferred to the cavity wall of the second mold cavity 223a through the flexible body 510a and the second mold body 221a, so as to melt and thaw the ice body and the cavity wall of the second mold cavity 223a. In this embodiment, the heating element can be a heating wire.

[0261] In one embodiment, the flexible body 510a is configured as a silicone body, which is a high-temperature resistant silicone body, at least resistant to high temperatures of about 150°C; however, the present design is not limited to this. In other embodiments, the flexible body 510a can also be configured as a foil-like or thin-sheet metal body, as long as it has a certain degree of bending flexibility and a certain degree of thermal conductivity.

[0262] In one embodiment, referring to Figure 13, the flexible body 510a includes a plurality of flexible petals 511a arranged in sequence in the circumferential direction of the second mold 220a, and the plurality of flexible petals 511a jointly cover the back side of the cavity wall of the second mold cavity 223a. The plurality of flexible petals 511a jointly cover the back side of the cavity wall of the second mold cavity 223a. When the second mold 220a only includes the second mold body 221a, the back side of the cavity wall of the second mold cavity 223a is the outer surface of the second mold body 221a.

[0263] In one embodiment, referring to Figures 17 and 18, the ice maker further includes an ejector 30a and a driving member 60a, wherein the ejector is movably mounted on the second mold 220a and can movably extend into the second mold cavity 223a, and the driving member is drivingly connected to the ejector. In this embodiment, the driving member is configured as a ejector rod or an electric telescopic rod (not shown); during the ice-removing process, the ejector can separate the ice body from the cavity wall of the second mold cavity 223a by ejecting.

[0264] Furthermore, when the ice maker also includes an ejector 30a and a driving member 60a, the mold assembly 200a can adopt the following method during the ice defrosting process; during the ice defrosting process, a high-temperature refrigerant is introduced into the first flow channel 214a to thaw the produced ice body and the first mold 210a, and then the driving assembly 300a drives the second mold 220a to flip to the second position, and then the driving member 60a drives the ejector to eject the ice body from the second mold 220a. Furthermore, in this embodiment, referring to Figures 17 and 23 to 25, when the driving member 60a is configured as a push rod 61a, the driving member 60a further includes a mounting plate 62a, and the mounting plate 62a is fixedly arranged. Specifically, the mounting plate 62a is fixed to the frame, and the push rod 61a is fixed to the mounting plate 62a, wherein the push rod 61a is located in the second position; further, the ice maker further includes a guide member 50a for mounting the ejector 30a, the guide member 50a is fixed to the second mold 220a, and the guide member 50a includes a guide tube 51a, a push plate 52a, a first limiting structure 53a, a second limiting structure 54a, and the ejector 30a and the push plate 52a They are all arranged in the guide tube 51a, and the ejector 30a and the push plate 52a are fixed to each other. A second spring 70a is arranged between the push plate 52a and the first limiting structure 53a. When de-icing, the second driving assembly 300a drives the second mold 220a to flip close to the second position. When close to the second position, the ejector rod 61a contacts the push plate 52a, thereby pushing the push plate 52a. The push plate 52a compresses the second spring 70a and extends the ejector 30a from the guide tube 51a, so that the ejector 30a extends into the second mold cavity 223a; when completely located in the second position, the stroke of the ejector 30a extending into the second mold cavity 223a is the maximum. When the second mold 220a leaves the second position, the push plate returns to its initial position under the action of the restoring force of the second spring 70a, thereby driving the ejector 30a to retract into the guide tube 51a, and the second limiting structure 54a is used to limit the ejector 30a in the guide tube 51a to prevent the ejector 30a from detaching from the guide tube 51a; specifically, in the present application, the guide tube 51a is arranged to cover at least part of the second mold 220a, and the first limiting structure 53a is configured as a partial structure of the second mold 220a located in the guide tube 51a. Under the action of the first limiting structure 53a, the push plate 52a and the ejector 30a can be prevented from being ejected from the guide tube 51a by the restoring force of the second spring 70a. When the driving member is configured as an electric telescopic rod (not shown), wherein the electric telescopic rod can be installed on the frame 100a or on the second mold 220a, when the second mold 220a moves to the second position, the electric telescopic rod ejects the ejector 30a, so that the ejector 30a separates the ice body from the second mold 220a; when the second mold 220a moves to the first position, the electric telescopic rod retracts the ejector 30a.During the ice-removing process, a high-temperature refrigerant is introduced into the first flow channel 214a to thaw the prepared ice body and the first mold 210a, and then the second mold 220a is driven to move to the second position by the driving component 300a. The driving component drives the ejector 30a to eject the ice body from the second mold 220a.

[0265] In one embodiment, referring to Figure 25, the ejector 30a can be configured as a mounting seat 410a in the spray assembly 400a, and the push plate 52a in the guide member 50a is provided with an avoidance hole for the second water inlet channel 420a to pass through. At the same time, the second mold 220a is provided with a mounting hole 224a for the mounting seat 410a to be installed, which has a limiting step 2241a, wherein the second limiting structure 54a is configured as a limiting step 2241a. During the ice removal process, the ejector rod 61a pushes the push plate 52a, and the push plate 52a compresses the spring 70a and ejects the mounting seat 410a from the mounting hole 224a, so that the mounting seat 410a extends into the second mold cavity 223a, and the ice body is ejected from the second mold cavity 223a. After de-icing is completed, the second mold 220a leaves the second position, and under the action of the restoring force of the spring 70a, the push plate 52a and the mounting seat 410a return to their original positions. At this time, the mounting seat 410a enters the mounting hole 224a, and under the action of the limiting step 2241a, the mounting seat 410a is restricted in the mounting hole 224a.

[0266] In one embodiment, the first mold 210a and the second mold 220a are made of a material with good thermal conductivity, preferably aluminum. The material with good thermal conductivity can facilitate the transfer of energy from the refrigerant, or high-temperature refrigerant, or heating element 500a, or thawing medium to the mold cavity.

[0267] In one embodiment, referring to Figures 14, 19, and 21, the ice maker further includes a spray assembly 400a, which includes a mounting base 410a having a water inlet channel 420a and a spray hole 430a, and a flow guide 440a mounted on the spray hole 430a. The mounting base 410a is mounted on the second mold 220a, the water inlet channel 420a is used for water input, and the flow guide 440a is used for dispersing the water sprayed through the spray hole 430a. In this embodiment, the flow guide 440a is configured as a spiral nozzle 441a or a spiral guide blade 442a. The second mold 220a is provided with a mounting hole 224a for mounting the mounting base 410a, and the mounting base 410a is fixed to the mounting hole 224a. When the spray assembly 400a sprays water toward the ice-making chamber 230a, water enters through the water inlet channel 420a and is then sprayed toward the ice-making chamber 230a through the spray hole 430a. Since a guide member 440a is provided in the water inlet channel 420a, the water sprayed through the spray hole 430a is dispersed. In this way, water spraying at multiple angles can be achieved, making it convenient to spray the ice-making chamber 230a more evenly, so that a more even layer of ice condenses on the ice-making chamber 230a.

[0268] In this embodiment, referring to FIG. 21 and FIG. 22 , when the guide member 440 a is configured as a spiral nozzle 441 a , the water sprayed toward the ice-making chamber 230 a through the spray hole 430 a can be dispersed.

[0269] In this embodiment, referring to Figures 19 and 20, when the spiral guide blade 442a is installed in the spray hole 430a, that is, when the guide member 440a is configured as a spiral guide blade 442a, a fluid spiral generating chamber 460a is formed between the spiral guide blade 442a and the spray hole 430a, and a conical structure 450a is formed between the fluid spiral generating chamber 460a and the spray hole 430a. The spiral guide blade 442a includes a dividing portion 4421a and two guide portions 4422a, and the two guide portions 4422a are both installed on the dividing portion 4421a. The guide portion 4422a is spiral-shaped, and the dividing portion 4421a is used to divide the water in the water inlet channel 420a into two parts. The two parts of water move spirally along the two guide portions 4422a respectively, and enter the fluid spiralization generating chamber 460a to generate spiral flow. Under the action of the conical structure 450a, the spirally moving water can better flow to the spray hole 430a. At this time, the water sprayed from the spray hole 430a can be dispersed, thereby realizing multi-angle water spraying, facilitating more uniform spraying in the ice-making chamber 230a, so that a more uniform ice layer is condensed on the ice-making chamber 230a.

[0270] In one embodiment, referring to Figure 12, the first mold 210a is further provided with an exhaust hole 260a. Furthermore, the second mold 220a is arranged below the first mold 210a; during the ice-making process, when the spray assembly 400a sprays water onto the cavity wall of the ice-making chamber 230a, the cavity wall can cool the water flow under the action of the refrigerant, so that the water flow can condense on the cavity wall of the ice-making chamber 230a. During the condensation process, the air between the water flow and the cavity wall of the ice-making chamber 230a can be discharged through the exhaust hole 260a, thereby facilitating the discharge of the air in the ice-making chamber 230a.

[0271] In one embodiment, the second mold 220a is further provided with a water return hole 225a. Furthermore, the second mold 220a is arranged below the first mold 210a, wherein the water return hole 225a can be opened in the second mold 220a. The water that has not condensed in the ice-making cavity 230a can be collected through the water return hole 225a, thereby preventing the water that has not condensed from accumulating in the second mold cavity 223a for a long time and causing it to condense, thereby blocking the spray hole 430a.

[0272] In one embodiment, referring to Figures 19 to 21, the return water hole 225a can be set in the mounting seat 410a installed on the second mold 220a. Specifically, the return water hole 225a is opened in the mounting seat 410a, and one end is connected to the second mold cavity 223a, and the other end is connected to the outside of the second mold 220a. In this embodiment, when the second mold 220a is set below the first mold 210a, the spray assembly 400a installed in the second mold 220a sprays water toward the ice-making cavity 230a. The sprayed water is upward. After being sprayed, some of the water that has not condensed in the ice-making cavity 230a will flow downward under the action of gravity and can flow into the return water hole 225a at this time. Furthermore, in order to facilitate the use of the return water hole 225a, the return water hole 225a is set at a lower position in the second mold cavity 223a. In this way, it is convenient for the return water hole 225a to collect uncondensed water. Furthermore, the return hole 225a is integrated into the mounting base 410a of the spray assembly 400a, which simplifies the installation process of the present application. After the spray assembly 400a is installed on the second mold 220a, its return hole 225a is also installed. In the present application, the return hole 225a is connected to the return water box, and water entering the return hole 225a flows into the return water box.

[0273] In one embodiment, referring to FIG18 , the ejector tube can be shared with the mounting seat 410a, that is, the ejector tube is movably mounted in the mounting hole 224a. At this time, the driving member is driven and connected to the mounting seat 410a. The driving member drives the mounting seat 410a so that the mounting seat 410a ejects the ice body from the second mold cavity 223a.

[0274] In one embodiment, the ice maker further includes an ice guide structure 600a. The ice guide structure 600a includes an ice guide plate. The ice guide plate is disposed below the mold assembly 200a. The ice guide plate is used to guide ice out of the ice maker.

[0275] In this embodiment, the ice guide plate can be a whole plate or composed of two parts. When the ice guide plate is composed of two parts, referring to Figures 10 and 11, the ice guide plate includes a first ice guide plate 610a and a second ice guide plate 620a. In this case, the ice guide structure 600a also includes a driving structure 630a, wherein the driving structure 630a includes a first swing arm 631a and a second swing arm 632a. The first swing arm 631a and the second swing arm 632a are both rotatably connected to the frame 100a. The first ice guide plate 610a is fixed to the first swing arm 631a, and the second ice guide plate 620a is fixed to the second swing arm 632a. A torsion spring 633a is provided between the first ice guide plate 610a and the second ice guide plate 620a and the frame 100a. Under the action of the torsion spring 633a, the first ice guide plate 610a can be rotated. The ice plate 610a and the second ice guide plate 620a are both located outside the mold assembly 200a; further, the driving structure 630a also includes a driving plate 634a, a transmission member 635a and a linear driving structure 636a, wherein the linear driving structure 636a drives the driving plate 634a to move linearly. Furthermore, the first swing arm 631a is arranged below the second swing arm 632a. When the linear driving structure 636a drives the driving plate 634a to move downward, the driving plate 634a can press down the first swing arm 631a, causing the first swing arm 631a to swing, thereby driving the first ice guide plate 610a to flip, so that the first ice guide plate 610a is located below the mold assembly 200a (see Figure 11). Furthermore, the transmission member 635a includes a transmission gear 6351a, a driving tooth 6352a provided on the driving plate 634a, and a third swing arm 6353a, wherein the transmission gear 6351a and the third swing arm 6353a are both mounted on the frame 100a, and the third swing arm 6353a and the transmission gear 6351a are meshed. That is, the third swing arm 6353a is provided with a driven gear 6354a that cooperates with the transmission gear 6351a. Specifically, When the transmission gear 6351a rotates, the third swing arm 6353a can swing under the action of the driven gear 6354a, and the third swing arm 6353a is driven and connected to the second swing arm 632a. When the third swing arm 6353a swings, the third swing arm 6353a can drive the second swing arm 632a to swing. The swing of the second swing arm 632a realizes the flipping of the second ice guide plate 620a, so that the second ice guide plate 620a is located below the mold assembly 200a.In this embodiment, when the linear drive structure 636a drives the drive plate 634a to move downward (see Figure 11), the drive teeth 6352a on the drive plate 634a can engage with the transmission gear 6351a. As the drive plate 634a continues to move toward the second position, the transmission gear 6351a rotates. When the transmission gear 6351a rotates, it drives the third swing arm 6353a to swing, so that the third swing arm 6353a drives the second swing arm 632a to swing, thereby realizing the flipping of the second ice deflector 620a, so that the second ice deflector 620a is located between the first mold 210a and the second mold 220a. When the linear drive structure 636a drives the drive plate 634a to move upward (see Figure 10), the drive tooth 6352a drives the transmission gear 6351a to rotate, thereby causing the third swing arm 6353a to return to its initial position. At this time, the second ice guide plate 620a returns to its initial state under the action of the torsion spring 633a, thereby being located outside the mold assembly 200a. At the same time, the drive plate 634a does not press down the first swing arm 631a, and the first ice guide plate 610a also returns to its initial state under the action of the torsion spring 633a, thereby being located outside the mold assembly 200a.

[0276] In one embodiment, referring to FIG13 , the first mold 210a, the second mold 220a, the spray assembly 400a, the first flow channel 214a, the second flow channel 227a, or the heating element 500a, or the ejector 30a are all configured as multiple groups and are arranged in a one-to-one correspondence; the ice maker further includes a first medium pipe group 700a and a water pipe group 800a, wherein the first medium pipe group 700a is used to pass refrigerant into the multiple first flow channels 214a; and the water pipe group 800a is used to pass water into the multiple spray assemblies 400a. In this embodiment, the provision of multiple groups of first molds 210a and second molds 220a enables the ice maker of the present application to have multiple ice making cavities 230a during a single ice making process, that is, to produce multiple ice bodies at a time, thereby effectively improving the ice making efficiency of the ice maker. Furthermore, by introducing refrigerant into the multiple first flow channels through the first medium pipe assembly 700a, the efficiency of the refrigerant entering the multiple first flow channels 214a can be improved. Similarly, the water pipe assembly 800a introduces water into the multiple water inlet channels 420a of the multiple spray assembly groups 400a, thereby improving the efficiency of water entering the multiple water inlet channels 420a. Furthermore, the multiple return holes 225a in the multiple spray assembly groups 400a can be connected to a single pipe and return to the return box.

[0277] In this embodiment, when the second mold 220a is provided with a second flow channel 227a, the present application may further provide a second medium pipe group (not shown) to pass the heat medium through the plurality of second flow channels 227a.

[0278] In one embodiment, referring to Figure 13, when the first mold 210a and the second mold 220a are configured in multiple, specifically, when the first mold 210a includes a first mold body 211a and a first mold cover 212a, multiple groups of first mold covers 212a in the first mold 210a are integrally formed, and multiple groups of first mold bodies 211a in the first mold 210a are integrally formed; when the second mold 220a includes a second mold body 221a and a second mold cover 222a, multiple groups of second mold covers 222a in the second mold 220a are integrally formed, and multiple groups of second mold bodies 221a in the second mold 220a are integrally formed; in this way, the production of the first mold 210a and the second mold 220a can be facilitated, and at the same time, the driving component 300a can conveniently drive the multiple second molds 220a to move synchronously.

[0279] When the thawing medium is configured as a heating element 500 a , a plurality of the heating elements 500 a are connected.

[0280] The present application also provides an ice making machine.

[0281] Please refer to Figures 31 and 32. In one embodiment of the present application, the ice maker includes:

[0282] Rack 100b;

[0283] The mold assembly 200b includes a first mold 210b and a second mold 220b. The first mold 210b is fixed to the frame 100b and has at least one first mold cavity 213b. The second mold 220b is movably mounted on the frame 100b and has at least one second mold cavity 223b.

[0284] The driving assembly 300b is mounted on the frame 100b and is drivingly connected to the second mold 220b, and is capable of driving the second mold 220b to move laterally so that the second mold 220b has a first position closed relative to the first mold 210b and a second position open relative to the first mold 210b. Specifically, in this embodiment, the driving assembly 300b drives the second mold 220b to move laterally, including horizontal and inclined lateral movements at a certain angle, but not vertical movement; when the driving assembly 300b drives the second mold 220b to the first position, the second mold 220b and the first mold 210b are aligned. 0b are combined, the first mold cavity 213b and the second mold cavity 223b form an ice-making cavity 230b, and the ice-making cavity 230b is used to make ice; wherein, one first mold cavity 213b and one second mold cavity 223b are correspondingly provided; when the number of the first mold cavity 213b and the second mold cavity 223b is set to one, the number of ice-making cavities 230b is one; when the number of the first mold cavity 213b and the second mold cavity 223b is set to three, the number of ice-making cavities 230b is also three; when ice making is completed, the driving assembly 300b drives the second mold 220b to the second position, and the ice can be separated from the mold assembly 200b. Furthermore, the structure of the ice made by the ice-making cavity 230b is determined by the structure of the ice-making cavity 230b. In this application, an embodiment in which the ice-making cavity 230b has a spherical structure is provided. However, the present design is not limited to the spherical structure. In other embodiments, the ice-making chamber 230b may also be an ellipsoid, a cylinder, a cube, or other structures that are convenient for demolding.

[0285] The technical solution of the present application uses a driving component 300b to drive the second mold 220b to move in a straight line, wherein the driving component 300b is configured as a linear driving component 300b; when ice making is required, the driving component 300b drives the second mold 220b to move laterally to move it to the first position, at which time the second mold 220b is merged with the first mold 210b, and the first mold cavity 213b and the second mold cavity 223b form an ice-making cavity 230b. By injecting water into the ice-making cavity 230b and then cooling the mold component 200b, the water in the ice-making cavity 230b is cooled. The temperature drops, causing the water to freeze into ice; when ice making is completed, the driving component 300b drives the second mold 220b to move, so that the second mold 220b moves to the second position. At this time, the mold opening of the mold component 200b is completed, and then the ice can be removed from the first mold cavity 213b or the second mold cavity 223b. In the present application, the second mold 220b is driven to move by the driving component 300b to realize the merging and opening of the mold component 200b, which can effectively improve the degree of automation of the mold opening of the ice maker during the ice making process, thereby solving the technical problems existing in the prior art.

[0286] In one embodiment, referring to Figures 32 and 33, the ice maker further includes a spray assembly 400b, which includes a mounting base 410b having a first water inlet channel 420b and a spray hole 430b, and a guide member 440b installed at the spray hole 430b. The mounting base 410b is installed at the second mold 220b, the first water inlet channel 420b is used for water input, and the guide member 440b is used for dispersing the water sprayed through the spray hole 430b. In this embodiment, the second mold 220b is provided with a mounting hole 224b for mounting the mounting base 410b, and the mounting base 410b is fixed to the mounting hole 224b. When the spray assembly 400b sprays water toward the ice-making chamber 230b, water enters through the first water inlet channel 420b and is then sprayed out of the ice-making chamber 230b through the spray holes 430b. Because the first water inlet channel 420b is provided with a flow guide 440b, the water sprayed out of the spray holes 430b is dispersed, thereby achieving multi-angle water spraying, facilitating a relatively uniform spraying of the ice-making chamber 230b, and ensuring a relatively uniform ice layer condenses in the ice-making chamber 230b. In this embodiment, during the ice-making process, the first mold cavity and the second mold cavity constitute an ice-making chamber, into which water is injected through the first water inlet channel.

[0287] In this embodiment, referring to FIG. 36 , the guide member 440b is configured as a spiral nozzle 441b or a spiral guide blade 442b. When the guide member 440b is configured as a spiral nozzle 441b, the water sprayed toward the ice-making chamber 230b through the spray hole 430b can be dispersed.

[0288] In this embodiment, referring to Figures 33 and 35, when the guide member 440b is configured as a spiral guide blade 442b, a fluid spiral generating chamber 460b is formed between the spiral guide blade 442b and the spray hole 430b, and a conical structure 450b is formed between the fluid spiral generating chamber 460b and the spray hole 430b. The spiral guide blade 442b includes a dividing portion 4421b and two guide portions 4422b. Both of the guide portions 4422b are installed on the dividing portion 4421b. The guide portion 4422b is spiral. The dividing portion 4421b is used to divide the water in the first water inlet channel 420b into two parts. The two parts of water move spirally along the two guide portions 4422b respectively and enter the fluid spiral generating chamber 460b to generate spiral flow. Under the action of the conical structure 450b, the spirally moving water can better flow to the spray hole 430b. At this time, the water sprayed from the spray hole 430b can be dispersed, thereby realizing multi-angle water spraying, facilitating more uniform spraying in the ice-making chamber 230b, so that a more uniform ice layer is condensed on the ice-making chamber 230b.

[0289] In one embodiment, referring to Figure 31, the ice maker further includes a water injection pipe 40b. When the first mold 210b and the second mold 220b are closed, a second water inlet channel 240b is formed between the first mold 210b and the second mold 220b on the upper side. The water injection pipe 40b is used to inject water into the closed first mold 210b and the second mold 220b through the second water inlet channel 240b. In this embodiment, water can be injected into the ice making chamber 230b through the water injection pipe 40b, and then the water in the ice making chamber 230b is cooled by the refrigerant to freeze it into an ice body.

[0290] In one embodiment, the second water inlet channel 240b includes a converging section 241b and a plurality of diverting sections 242b (see FIG. 43 ). The diverting section 242b communicates with the mold cavity, that is, communicates with the ice-making chamber 230b. The converging section 241b gradually expands from its connection with the diverting section 242b toward the water inlet of the second water inlet channel 240b. This increases the area of ​​the water inlet of the second water inlet channel 240b. When the water injection pipe 40b injects water into the second water inlet channel 240b, the water easily enters the second water inlet channel 240b and then enters the ice-making chamber 230b through the plurality of diverting sections 241b. Furthermore, the provision of multiple diverting sections 242b allows water in the converging section 241b to enter the ice-making chamber 230b more quickly.

[0291] During the ice-making process, the water injection pipe 40b can be used together with the spray assembly 400b, so that the ice-making machine of the present application has two water injection structures during the ice-making process. When the two water injection structures operate simultaneously, the water injection time can be effectively shortened, the water injection efficiency can be improved, and the ice-making efficiency can be improved. Furthermore, when the water injection pipe 40b and the spray assembly 400b are used together, the water injection pipe 40b can be filled with water first and then the spray assembly 400b, or the spray assembly 400b can be filled with water first and then the water injection pipe 40b, or the spray assembly 400b and the water injection pipe 40b can be filled with water simultaneously. Alternatively, only the water injection pipe 40b can be used to inject water into the ice-making chamber 430b. Alternatively, only the spray assembly 400b can be used to inject water into the ice-making chamber 430b.

[0292] In one embodiment, referring to Figures 32 and 38 , the first mold 210b is provided with a first flow channel 214b for circulating a refrigerant. In this embodiment, the first mold 210b can have different effects depending on the temperature of the refrigerant entering the first flow channel 214b. When the temperature of the refrigerant is relatively low, the refrigerant freezes the water in the ice-making cavity 230b. When the temperature of the refrigerant is relatively high, the refrigerant thaws the ice cubes and the walls of the first mold cavity 213b.

[0293] In one embodiment, referring to Figures 32 and 38, the first flow channel 214b includes a plurality of circles of flow channels 2141b that are connected in sequence in a direction away from the second mold 220b. Specifically, the plurality of circles of flow channels 2141b are arranged around the first mold cavity 213b, that is, the first flow channel 214b is arranged around the first mold cavity 213b. Under the action of the plurality of circles of flow channels 2141b, the relative contact area between the first flow channel 214b and the first mold cavity 213b can be increased. At this time, after the refrigerant is passed into the first flow channel 214b, due to the increase in the relative contact area between the first flow channel 214b and the first mold cavity 213b, the energy of the refrigerant can be transferred to the ice-making cavity 230b more quickly, thereby causing the ice-making cavity 230b to cool down quickly, thereby achieving the purpose of quickly freezing the water in the ice-making cavity 230b.

[0294] In one embodiment, referring to Figures 32 and 38, for any circle flow channel 2141b in the middle, its connection with the adjacent circle flow channel 2141b close to the second mold 220b and its connection with the adjacent circle flow channel 2141b away from the second mold 220b are respectively arranged on opposite sides of the circle flow channel 2141b, that is, when the refrigerant enters the first flow channel 214b, it first enters the flow channel 2141b of the upper layer, and then flows along the flow channel 2141b of the upper layer to the connection, and then enters the flow channel 2141b of the middle layer through the connection. , and then flows along the middle layer flow channel 2141b to the connecting point, at this time it flows into the lower layer flow channel 2141b through the connecting point of the middle layer flow channel 2141b and the lower layer flow channel 2141b. At this time, the flow direction of the refrigerant in the upper layer flow channel 2141b is opposite to the flow direction in the lower layer flow channel 2141b, so as to avoid the refrigerant directly entering the middle layer and the lower layer flow channels 2141b from the upper layer flow channel 2141b, and can increase the flow path of the refrigerant in the first flow channel 214b, thereby increasing the relative contact area between the refrigerant and the first mold cavity 213b.

[0295] In one embodiment, referring to Figures 32 and 38, the first mold 210b can adopt the following structure, wherein the first mold 210b includes a first mold body 211b and a first mold cover 212b, the first mold cover 212b is arranged to cover the first mold body 211b, the first mold cavity 213b is formed on the side of the first mold body 211b away from the first mold cover 212b, and the first runner 214b is formed between the first mold cover 212b and the first mold body 211b. Specifically, the first runner 214b is formed between the first mold cover 212b and the first mold body 211b so as to be arranged around the first mold body 211b, thereby achieving the purpose of surrounding the first mold cavity 213b, and the first runner 214b surrounds the first mold body 211b one or more circles, thereby achieving the first runner 214b surrounding the first cavity one or more circles. In this embodiment, the first mold cover 212b is configured as a special-shaped cover, and a groove structure (not shown) is formed in the first mold cover 212b. When the first mold cover 212b covers the first mold body 211b, the first flow channel 214b is formed outside the first mold body 211b. In this case, the first flow channel 214b is located between the first mold cover 212b and the first mold body 211b. At the same time, when the wall thickness of the first mold cavity 213b is uniform, the energy in the first flow channel 214b surrounding the outside of the first mold body 211b can be evenly transferred to the first mold cavity 213b through the first mold body 211b, thereby achieving more uniform freezing of the ice-making cavity 230b and more uniform thawing during the thawing process, resulting in a more complete ice body after thawing.

[0296] However, the present design is not limited to this. In other embodiments, the first mold 210b may also adopt other structures. For example, the first mold 210b may only include the first mold body 211b. In this case, the first flow channel 214b is formed on the outside of the first mold body 211b. Specifically, a pipeline (not shown) is fixed to the outside of the first mold body 211b, and the first flow channel 214b is set in the pipeline, wherein the pipeline can be arranged around the outside of the first mold body 211b in one or more circles.

[0297] In the present application, the ice making machines in Figures 32 and 37 all use the above-mentioned first mold 210b, wherein the first flow channel 214b includes multiple circles of flow channels 2141b that are sequentially connected in the direction away from the second mold 220b. The structures of the first molds used are similar, and the only differences are the first mold body 211b, the first mold cavity 213b, the number of first flow channels 214b and the length of the first mold cover.

[0298] In one embodiment, referring to Figures 40 and 41, the first mold 210b is embedded with a copper tube 217b, which is used for the circulation of refrigerant. The first mold cavity 213b is formed on the side of the first mold body 210b away from the copper tube 217b. By passing refrigerants of different temperatures into the copper tube 217b, the copper tube 217 transfers the energy of the refrigerant to the first mold 210b, and then transfers it to the first mold cavity 213b, thereby freezing the water in the ice-making cavity 230b, or thawing the ice body and the cavity wall of the first mold cavity 213b.

[0299] In one embodiment, the first mold 210b includes a first mold cover 212b and two first mold bodies 211b (an embodiment with only two first mold bodies 211b is not shown in the figure), and the two first mold bodies 211b are respectively arranged on opposite sides of the first mold cover 212b, and the first mold cover 212b covers at least part of the two first mold bodies 211b, and the first mold cavity 213b is formed on the side of the first mold body 211b away from the first mold cover 212b, and the first mold cover 212b and the two first mold bodies 211b together form the first flow channel 214b (see Figures 43 and 45); in this way, the first mold cavities 213b in the two first mold bodies 211b can share one first flow channel 214b, that is, when the refrigerant is injected into the first flow channel 214b, the energy in the refrigerant can be transferred to the two first mold cavities 213b through the two first mold bodies 211b. Specifically, during the ice-making process, after the refrigerant enters the first flow channel 214b, the refrigerant in the first flow channel 214b can cool the first mold cavity 213b in the two first mold bodies 211b, and the two ice-making cavities 230b formed by the two first mold bodies 211b and the two first molds 210b are cooled, thereby causing the water injected and or sprayed into the ice-making cavity 230b to condense into ice. In this way, the ice-making machine of the present application can make multiple ices at a time, and by having two ice-making cavities 230b share one first flow channel 214b, the production cost of the ice-making machine can be reduced.

[0300] In one embodiment, referring to Figures 42, 44, and 46, the first flow channel 214b can adopt the following structure: the two first mold bodies 211b are arranged at intervals along the first direction, further, the first direction is parallel to the moving direction of the second mold 220b, the first flow channel 214b includes a plurality of flow channels 2141b arranged between the two first mold bodies 211b, the plurality of flow channels 2141b are arranged in sequence along the second direction, the second direction is perpendicular to the first direction, for any one section of the flow channel 2141b in the middle, the two connecting points with the two adjacent sections of the flow channel 2141b are respectively provided at the opposite ends of the section of the flow channel 2141b along the first direction (see Figure 48); the second mold 220b is provided in a one-to-one correspondence with the first mold body 211b, and the two second molds 220b are respectively provided on the opposite sides of the first mold 210b. Specifically, when the refrigerant enters the first flow channel 214b, the first It enters an outer flow channel 2141b, then flows along the flow channel 2141b to the connection between the outer flow channel 2141b and the middle flow channel 2141b, enters the middle flow channel 2141b through this connection, and then continues to flow along the middle flow channel 2141b to the connection between the middle flow channel 2141b and another outer flow channel 2141b, and enters the outer flow channel 2141b through this connection. Since any section of the middle flow channel 2141b has two connection points with the two adjacent sections of the flow channel 2141b respectively arranged at the opposite ends of the section of the flow channel 2141b along the first direction, in this way, the refrigerant in the first flow channel 214b in this embodiment can flow in a winding manner (see Figure 48). Under the action of this flow mode, the contact area between the first flow channel 214b and the two first mold bodies 211b can be increased, thereby increasing the relative contact area between the first mold cavity 213b and the refrigerant, thereby improving the energy transmission effect.

[0301] In one embodiment, when multiple first mold bodies 211b are located on the same side of the first mold cover 212b, multiple second molds 220b are also located on the same side of the first mold cover 212b (see Figures 42 to 47). This means that multiple ice-making cavities 230b are located on the same side of the first mold cover 212b. Furthermore, when multiple ice-making cavities 230b are located on the first mold cover 212b, the water injection pipe 40b injects water into the multiple second water inlet channels 240b. In this case, the water injection pipe 40b acts as a diverter. The first mold cover 212b is provided with multiple first flow channels 214b corresponding one-to-one to the multiple first mold bodies 211b. Adjacent first flow channels 214b are separated by a partition 270b (see Figure 48). This facilitates installation of the first mold 210b and reduces the cost of the first mold 210b. However, the present design is not limited thereto. In other embodiments, the first mold cover 212b and the two first mold bodies 211b may only enclose one first flow channel 214b.

[0302] In one embodiment, a first flow channel 214b is provided corresponding to the first mold bodies 211b symmetrically disposed on opposite sides of the first mold cover 212b (see Figures 47 and 48). Specifically, one first flow channel 214b is provided corresponding to two first mold bodies 211b. However, the present design is not limited thereto. In other embodiments, one first flow channel 214b may be provided corresponding to four or more first mold bodies 211b. In other words, the first mold cover 212b and multiple first mold bodies 211b together form one first flow channel 214b.

[0303] In one embodiment, when the first mold cavity and the second mold cavity are combined, the first mold cavity 213b and the second mold cavity 223b form an ice-making cavity 230b. The ice-making cavities located on both sides of the first mold cover have different structures or sizes. When the ice-making cavities located on both sides of the first mold cover have different structures, one of the ice-making cavities located on both sides of the first mold cover may have a quadrangular prism structure, and the ice bodies produced therefrom may have a quadrangular prism structure, while the other may have a spherical structure, and the ice bodies produced therefrom may have a spherical structure. When the ice-making cavities located on both sides of the first mold cover have different sizes, one may have a larger spherical structure, and the ice bodies produced therefrom may have a larger spherical structure, while the other may have a smaller spherical structure, and the ice bodies produced therefrom may have a smaller spherical structure.

[0304] In the present application, the ice-making machines in Figures 42 to 48 all use the above-mentioned first mold 210b, wherein the first mold cover 212b and the two first mold bodies 211b together form the first flow channel 214b. The structures of the first molds used are similar, and the only differences are the number of first mold bodies 211b, first mold cavities 213b, first flow channels 214b, and the length of the first mold cover. At the same time, in the present application, when second molds 220b are provided on both sides of the first mold cover 212b, the corresponding drive assemblies 300b can also be provided in two groups (see Figures 43, 45, and 47). When the drive assemblies 300b are provided in two groups, depending on the structure and size of the ice body to be produced, the ice-making cavities on both sides of the first mold cover can be opened simultaneously or sequentially when the mold is opened.

[0305] In one embodiment, the second mold 220b is provided with a second flow channel (not shown) for circulating a thawing medium. During the de-icing process, the thawing medium is introduced into the second flow channel to thaw the produced ice body and the second mold 220b, and then the second mold 220b is driven to move to the second position by the driving component 300b, and then a high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210b. During the de-icing process, a high-temperature refrigerant can also be introduced into the first flow channel 214b to thaw the produced ice body and the first mold 210b, and then the second mold 220b is driven to move to the second position by the driving component 300b, and then a thawing medium is introduced into the second channel to thaw the ice body and the second mold 220b. During the de-icing process, a high-temperature refrigerant can be introduced into the first flow channel 214b and a thawing medium can be introduced into the second channel to thaw the prepared ice body and the first mold 210b and the second mold 220b, and then the second mold 220b is driven to move to the second position by the driving component 300b.

[0306] In this embodiment, the second flow channel includes multiple circles of flow channels (not shown) connected in sequence in a direction away from the first mold 210b, and the multiple circles of flow channels in the second flow channel are similar or identical in structure to the multiple circles of flow channels 2141b in the first flow channel 214b.

[0307] In this embodiment, the second mold 220b includes a second mold body 221b and a second mold cover 222b. The second mold cover 222b is arranged to cover the second mold body 221b. The second mold cavity 223b is formed on the side of the second mold body 221b facing away from the second mold cover 222b. The second flow channel is provided between the second mold body 221b and the second mold cover 222b. In this embodiment, the second mold cover 222b is configured as a special-shaped cover and has a groove structure (not shown) formed therein. When the second mold cover 222b covers the second mold body 221b, the second flow channel is formed outside the second mold body 221b. In this case, the second flow channel is located between the second mold cover 222b and the second mold body 221b.

[0308] However, the present design is not limited to this. In other embodiments, the second mold 220b may also adopt other structures. For example, the second mold 220b may only include the second mold body 221b. In this case, the second flow channel is formed on the outside of the second mold body 221b. Specifically, a pipeline (not shown) is fixed to the outside of the second mold body 221b, and the second flow channel is arranged in the pipeline, wherein the pipeline can be arranged around the outside of the second mold body 221b in one or more circles.

[0309] In one embodiment, referring to Figures 32, 33, and 34, the cavity wall of the second mold cavity 223b is set to be of equal or nearly equal thickness, and the ice maker also includes a heating element 500b covering the back side of the cavity wall of the second mold cavity 223b. When the cavity wall of the second mold cavity 223b has the same thickness, the energy in the heating element 500b covering the back side of the cavity wall of the second mold cavity 223b can be evenly transferred to the second mold cavity 223b through the second mold body 221b, thereby achieving a more uniform freezing of the ice-making cavity 230b, or a more uniform thawing during the thawing process, so that the thawed ice body is more complete. In this embodiment, when the second mold 220b only includes the second mold body 221b, the back of the wall of the second mold cavity 223b is the outer surface of the second mold body 221b; further, when the ice body and the wall of the second mold cavity 223b are thawed by the heating element 500b, the heating element 500b can be configured as a heating film, which generates heat through the heating element 500b and transfers the heat through the second mold body 221b to the second mold cavity 223b, thereby melting and thawing the ice body and the wall of the second mold cavity 223b. During the de-icing process, the heating element 500b generates heat to thaw the prepared ice body and the second mold 220b, and then the second mold 220b is driven to move to the second position by the driving component 300b, and then a high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210b. During the de-icing process, a high-temperature refrigerant may be introduced into the first flow channel 214b to thaw the produced ice body and the first mold 210b, and then the driving assembly 300b drives the second mold 220b to move to the second position, and then the heating element 500b generates heat to thaw the ice body and the second mold 220b. During the de-icing process, a high-temperature refrigerant may be introduced into the first flow channel 214b, and then the heating element 500b generates heat to thaw the produced ice body and the first mold 210b and the second mold 220b, and then the driving assembly 300b drives the second mold 220b to move to the second position.

[0310] In one embodiment, referring to Figures 38 and 39, the ice maker further includes an ejector 30b and a driving member 60b, wherein the ejector 30b is movably mounted on the second mold 220b, and the ejector 30b can be movably extended into the second mold cavity 223b, and the driving member cooperates with the ejector 30b to movably extend the ejector 30b into the second mold cavity 223b. In this embodiment, the driving member is configured as a push rod 61b or an electric telescopic rod (not shown); when the driving member is configured as the push rod 61b, the push rod 61b is fixed to the frame 100b and is located at the second position of the second mold 220b. The ice maker also includes a guide member 50b for mounting the ejector 30b. The guide member 50b is fixed to the second mold 220b. The guide member 50b includes a guide tube 51b, a push plate 52b, a first limiting structure 53b, and a second limiting structure 54b. The ejector 30b and the push plate 52b are both arranged in the guide tube 51b, and the ejector 30b and the push plate 52b are fixedly arranged, and a second spring 70b is provided between the push plate 52b and the first limiting structure 53b. When de-icing, the second driving assembly 300b drives the second mold 220b to move close to the second position. When close to the second position, the ejector rod 61b contacts the push plate 52b, thereby pushing the push plate 52b. The push plate 52b compresses the second spring 70b and extends the ejector 30b from the guide tube 51b, so that the ejector 30b extends into the second mold cavity 223b; when completely located at the second position, the stroke of the ejector 30b extending into the second mold cavity 223b is the maximum. When the second mold 220b leaves the second position, the push plate returns to its initial position under the action of the restoring force of the second spring 70b, thereby driving the ejector 30b to retract into the guide tube 51b, and the second limiting structure 54b is used to limit the ejector 30b in the guide tube 51b to prevent the ejector 30b from detaching from the guide tube 51b; specifically, in the present application, the guide tube 51b is arranged to cover at least part of the second mold 220b, and the first limiting structure 53b is configured as a partial structure of the second mold 220b located in the guide tube 51b. Under the action of the first limiting structure 53b, the push plate 52b and the ejector 30b can be prevented from being ejected from the guide tube 51b by the restoring force of the second spring 70b. When the driving member is configured as an electric telescopic rod (not shown), wherein the electric telescopic rod can be installed on the frame 100b or on the second mold 220b, when the second mold 220b moves to the second position, the electric telescopic rod ejects the ejector 30b, so that the ejector 30b separates the ice body from the second mold 220b; when the second mold 220b moves to the first position, the electric telescopic rod retracts the ejector 30b.During the de-icing process, a high-temperature refrigerant is introduced into the first flow channel 214b to thaw the prepared ice body and the first mold 210b, and then the second mold 220b is driven to move to the second position by the driving component 300b. The driving component drives the ejector 30b to eject the ice body from the second mold 220b.

[0311] In one embodiment, referring to Figures 38 and 39, the ejector 30b can be configured as a mounting seat 410b in the spray assembly 400b, and the push plate 52b in the guide member 50b is provided with an avoidance hole for the first water inlet channel 420b to pass through. At the same time, the second mold 220b is provided with a mounting hole 224b for the mounting seat 410b to be installed, and has a limiting step 2241b, wherein the second limiting structure 54b is configured as a limiting step 2241b. During the ice removal process, the ejector rod 61b pushes the push plate 52b, and the push plate 52b compresses the second spring 70b and ejects the mounting seat 410b from the mounting hole 224b, so that the mounting seat 410b extends into the second mold cavity 223b, and the ice body is ejected from the second mold cavity 223b. After de-icing is completed, the second mold 220b leaves the second position, and under the action of the restoring force of the second spring 70b, the push plate 52b and the mounting seat 410b return to their original positions. At this time, the mounting seat 410b enters the mounting hole 224b, and under the action of the limiting step 2241b, the mounting seat 410b is restricted in the mounting hole 224b.

[0312] In one embodiment, when the first mold 210b and the second mold 220b are closed, a water return hole 250b is formed on the lower side between the first mold 210b and the second mold 220b. Under the action of the water return hole 250b, during the ice making process, some water that has not condensed in the ice making chamber 230b will flow downward under the action of gravity and can flow into the water return hole 250b. Furthermore, to facilitate the use of the water return hole 250b, the water return hole 250b is set at a lower position in the mold assembly 200b. In the present application, in order to collect the water in the water return hole 250b, a collection box (not shown) can be set below the water return hole 250b.

[0313] In one embodiment, the mold assembly 200b further comprises an exhaust hole 260b (see Figures 33, 35, and 41). In this embodiment, the exhaust hole 260b can be provided on the first mold 210b or the second mold 220b. During the ice-making process, when the spray assembly 400b sprays water onto the walls of the ice-making chamber 230b and / or the water injection pipe 40b injects water into the ice-making chamber 230b, the refrigerant cools the water flow on the walls of the ice-making chamber 230b, causing the water flow to condense on the walls of the ice-making chamber 230b. During the condensation process, air between the water flow and the walls of the ice-making chamber 230b can be discharged through the exhaust hole 260b, thereby facilitating the exhaust of air from the ice-making chamber 230b and improving the quality of the ice. Furthermore, in this embodiment, the exhaust hole 260b can also be provided on the mounting seat 410b of the spray assembly 400b.

[0314] In one embodiment, referring to FIG32, the driving assembly 300b includes a worm 310b, a worm 310b sleeve, a driving motor 330b and a guide rod 340b. The worm 310b is mounted on the frame 100b. The worm 310b sleeve is movably mounted on the worm 310b and fixed to the second mold 220b. The driving motor 330b is connected to the worm 310b in a driving manner. The second mold 220b is slidably matched with the guide rod 340b. The rod 340b is fixed to the frame 100b; specifically, the worm 310b is driven to rotate by the driving motor 330b. At this time, the worm 310b sleeve movably installed on the worm 310b can move up and down along the worm 310b. When the worm 310b moves up and down, it can drive the second mold 220b to move in a straight line. When the second mold 220b moves in a straight line, it can slide along the guide rod 340b, thereby achieving the purpose of the driving structure 630b driving the second mold 220b to move in a straight line. The drive assembly 300b also includes a synchronous belt 370b and multiple synchronous pulleys 380b (see FIG45 ). The multiple synchronous pulleys 380b are mounted on the worm 310b and the output end of the drive motor 330b. Furthermore, the output end of the drive motor 330b is connected to the synchronous pulley 380b via a differential. The synchronous belt 370b connects the multiple synchronous pulleys 380b. When the drive motor 330b rotates, the synchronous pulleys 380b and the synchronous belt 370b can drive the worm 310b to rotate. Furthermore, in this embodiment (see FIG45 ), the worm 310b and the worm 310b sleeve are each configured in two sets. The two sets of worm 310b are respectively disposed on either side of the second mold 220b, and both sets of worm 310b sleeves are fixed to the second mold 220b. The driving motor 330b is connected to the two groups of worm gears 310b through a synchronous belt 370b and a synchronous wheel 380b. Specifically, synchronous wheels 380b are provided on the output ends of the two groups of worm gears 310b and the driving motor 330b, and the synchronous belt 370b is connected to the three synchronous wheels 380b. At this time, the output end of the driving motor 330b rotates, and the synchronous wheel 380b and the synchronous belt 370b can drive the two groups of worm gears 310b to rotate simultaneously, thereby realizing the straight line movement of the second mold 220b.

[0315] In one embodiment, when the ice maker includes two sets of drive assemblies 300b, the two sets of drive assemblies are symmetrically arranged (see Figures 41, 43, and 45).

[0316] In one embodiment, the ice maker further includes an ice guide structure 600b. Referring to Figures 29 and 30, the ice guide structure 600b includes an ice guide plate. The ice guide plate is disposed below the mold assembly 200b and is used to guide ice out of the ice maker.

[0317] In this embodiment, the ice deflector plate can be a whole plate or composed of two parts.

[0318] 29 and 30, when the ice guide plate is composed of two parts, the ice guide plate includes a first ice guide plate 610b and a second ice guide plate 620b. At this time, the ice guide structure 600b also includes a driving structure 630b, wherein the driving structure 630b includes a first swing arm 631b and a second swing arm 632b. The first swing arm 631b and the second swing arm 632b are both rotatably connected to the frame 100b. The first ice guide plate 610b is fixed to the first swing arm 631b, and the second ice guide plate 620b is fixed to the second swing arm 632b. A torsion spring 633b is provided between the first ice guide plate 610b and the second ice guide plate 620b and the frame 100b. Under the action of the torsion spring 633b, the ice guide plate 610b and the second ice guide plate 620b can be rotated. The first ice guide plate 610b and the second ice guide plate 620b are both located outside the mold assembly 200b; further, the driving structure 630b also includes a driving plate 634b, a transmission member 635b and a linear driving structure 630b, wherein the linear driving structure 630b drives the driving plate 634b to move linearly. Furthermore, the first swing arm 631b is arranged below the second swing arm 632b. When the linear driving structure 630b drives the driving plate 634b to move downward, the driving plate 634b can press down the first swing arm 631b, causing the first swing arm 631b to swing, thereby driving the first ice guide plate 610b to flip, so that the first ice guide plate 610b is located below the mold assembly 200b. Furthermore, the transmission member 635b includes a transmission gear 6351b, a driving tooth 6352b provided on the driving plate 634b, and a third swing arm 6353b, wherein the transmission gear 6351b and the third swing arm 6353b are both mounted on the frame 100b, and the third swing arm 6353b and the transmission gear 6351b are meshed with each other, that is, the third swing arm 6353b is provided with a driven gear 6354b that cooperates with the transmission gear 6351b. Specifically, when the transmission gear 6351b is engaged with the third swing arm 6353b, When the driven gear 6351b rotates, the third swing arm 6353b can swing under the action of the driven gear 6354b, and the third swing arm 6353b is driven and connected to the second swing arm 632b. When the third swing arm 6353b swings, the third swing arm 6353b can drive the second swing arm 632b to swing, and the swing of the second swing arm 632b realizes the flipping of the second ice guide plate 620b, so that the second ice guide plate 620b is located below the mold assembly 200b (see Figure 30). In this embodiment, when the linear drive structure 630b drives the drive plate 634b to move downward (see Figure 30), the drive teeth 6352b on the drive plate 634b can engage with the transmission gear 6351b. As the drive plate 634b continues to move toward the second position, the transmission gear 6351b rotates. When the transmission gear 6351b rotates, it drives the third swing arm 6353b to swing, so that the third swing arm 6353b drives the second swing arm 632b to swing, thereby realizing the flipping of the second ice guide plate 620b, so that the second ice guide plate 620b is located between the first mold 210b and the second mold 220b.When the linear drive structure 630b drives the drive plate 634b upward (see FIG. 29 ), the drive gear 6352b drives the transmission gear 6351b to rotate, thereby causing the third swing arm 6353b to return to its initial position. The second ice deflector 620b, under the action of the torsion spring 633b, then returns to its initial position, positioned outside the mold assembly 200b. Simultaneously, the drive plate 634b no longer presses down on the first swing arm 631b, and the first ice deflector 610b, also under the action of the torsion spring 633b, returns to its initial position, positioned outside the mold assembly 200b. Furthermore, if the ice maker includes a collection box, when the linear drive structure 630b drives the drive plate 634b downward, the first ice deflector 610b and the second ice deflector 620b are positioned between the collection box and the mold assembly 200b.

[0319] The present application provides an ice making machine.

[0320] Please refer to Figures 49, 59, 60, and 61. In one embodiment of the present application, the ice maker includes:

[0321] Rack 100;

[0322] The mold assembly 200 includes a first mold 210 and a second mold 220. The first mold 210 is fixed to the frame 100 and has at least one first mold cavity 213. The second mold 220 is movably mounted on the frame 100 and has at least one second mold cavity 223.

[0323] The driving assembly 300 is mounted on the frame 100 and is connected to the second mold 220, and can drive the second mold 220 to move in a straight line so that the second mold 220 has a first position (see Figures 58 and 59) closed relative to the first mold 210 and a second position (see Figures 60 and 61) open relative to the first mold 210; when the driving assembly 300 drives the second mold 220 to the first position, the second mold 220 is merged with the first mold 210, and the first mold cavity 213 and the first mold cavity 213 are connected. The second mold cavity 223 constitutes an ice-making cavity 230, which is used to make ice. A first mold cavity 213 and a second mold cavity 223 are correspondingly arranged; when the number of the first mold cavity 213 and the second mold cavity 223 is set to one, the number of the ice-making cavity 230 is one; when the number of the first mold cavity 213 and the second mold cavity 223 is set to three, the number of the ice-making cavity 230 is also three; when ice making is completed, when the driving assembly 300 drives the second mold 220 to the second position, ice can be separated from the mold assembly 200.

[0324] The first mold 210 is provided with a first flow channel 214 for circulating refrigerant. The first flow channel 214 includes multiple loops of flow channels 2141 that connect sequentially in a direction away from the second mold 220. Specifically, the multiple loops of flow channels 2141 surround the first mold cavity 213. In other words, the first flow channel 214 surrounds the first mold cavity 213. In this embodiment, the first mold 210 can achieve different effects depending on the temperature of the refrigerant entering the first flow channel 214. When the temperature of the refrigerant is low, the refrigerant freezes the water in the ice-making cavity 230. When the temperature of the refrigerant is high, the refrigerant thaws the ice and the walls of the first mold cavity 213.

[0325] In this embodiment, since the first flow channel 214 includes multiple circles of flow channels 2141 (see Figures 53, 59, and 61) that are connected in sequence in a direction away from the second mold 220, the relative contact area between the first flow channel 214 and the first mold cavity 213 can be increased under the action of the multiple circles of flow channels 2141. At this time, after the refrigerant is passed into the first flow channel 214, the relative contact area between the first flow channel 214 and the first mold cavity 213 is increased. At this time, the energy of the refrigerant can be transferred to the ice-making cavity 230 more quickly, thereby causing the ice-making cavity 230 to cool down quickly, thereby achieving the purpose of quickly freezing the water in the ice-making cavity 230.

[0326] In this embodiment, before ice making, the drive assembly 300 first drives the second mold 220 to move linearly to a first position. At this point, the second mold 220 merges with the first mold 210, and the first and second mold cavities 213 and 223 form an ice-making chamber 230. Once the ice-making chamber 230 is formed, water is injected into the chamber 230, and then a refrigerant is introduced into the first flow channel 214. Alternatively, after the ice-making chamber 230 is formed, a refrigerant is introduced into the first flow channel 214, and then water is injected into the chamber 230. The refrigerant cools the mold assembly 200, thereby cooling the water within the ice-making chamber 230 and causing it to freeze into ice. After a predetermined cooling period, the water within the ice-making chamber 230 is frozen into ice. After the water in the ice-making cavity 230 is completely frozen into ice, the drive assembly 300 drives the second mold 220 to move linearly to a second position. At this point, the second mold 220 is separated from the first mold 210, and the ice is now in either the first mold cavity 213 or the second mold cavity 223. When the ice is in the first mold cavity 213, it can be removed from the first mold cavity 213. When the ice is in the second mold cavity 223, it can be removed from the second mold cavity 223. In this embodiment, there are no restrictions on the method for removing the ice from the first mold cavity 213 or the second mold cavity 223. The ice can be removed by directly ejecting it from the first mold cavity 213 or the second mold cavity 223. Alternatively, the ice can be removed by using a higher-temperature refrigerant to melt and separate it from the walls of the first mold cavity 213 or the second mold cavity 223.

[0327] The technical solution of the present application uses a driving assembly 300 to drive the second mold 220 to move along a straight line, wherein the driving assembly 300 can be configured as a linear driving structure 630; when ice making is required, the driving assembly 300 drives the second mold 220 to move along a straight line to move it to the first position, at which time the second mold 220 is merged with the first mold 210, and the first mold cavity 213 and the second mold cavity 223 form an ice-making cavity 230. By injecting water into the ice-making cavity 230 and then cooling the mold assembly 200, the temperature of the water in the ice-making cavity 230 is reduced. The temperature is lowered, causing the water to freeze into ice; when ice making is completed, the driving component 300 drives the second mold 220 to move, so that the second mold 220 moves to the second position. At this time, the mold opening of the mold component 200 is completed, and then the ice can be removed from the first mold cavity 213 or the second mold cavity 223. In the present application, the second mold 220 is driven to move by the driving component 300 to realize the merging and mold opening of the mold assembly 200, which can effectively improve the degree of automation of the mold opening of the ice maker during the ice making process, thereby solving the technical problems existing in the prior art.

[0328] In one embodiment, for any circle flow channel 2141 in the middle, its connection point (not shown) with the adjacent circle flow channel 2141 close to the second mold 220 and its connection point with the adjacent circle flow channel 2141 away from the second mold 220 are respectively arranged on opposite sides of the circle flow channel 2141, that is, when the refrigerant enters the first flow channel 214, it first enters the flow channel 2141 of the upper layer, and then flows along the flow channel 2141 of the upper layer to the connection point, at this time, it enters the flow channel 2141 of the middle layer through the connection point, and then It flows along the middle layer flow channel 2141 to the connecting point, and at this time flows into the lower layer flow channel 2141 through the connecting point between the middle layer flow channel 2141 and the lower layer flow channel 2141. At this time, the flow direction of the refrigerant in the upper layer flow channel 2141 is opposite to the flow direction in the lower layer flow channel 2141. This can prevent the refrigerant from directly entering the middle layer and the lower layer flow channels 2141 from the upper layer flow channel 2141, and can increase the flow path of the refrigerant in the first flow channel 214, thereby increasing the relative contact area between the refrigerant and the first mold cavity 213.

[0329] In one embodiment, the first mold 210 may adopt the following structure. Referring to Figures 51, 52, and 53, the first mold 210 includes a first mold body 211 and a first mold cover 212. The first mold cover 212 is arranged to cover the first mold body 211, and the first mold cavity 213 is formed on the side of the first mold body 211 facing away from the first mold cover 212. The first flow channel 214 is formed between the first mold cover 212 and the first mold body 211. Specifically, the first flow channel 214 is formed between the first mold cover 212 and the first mold body 211 so as to surround the first mold body 211, thereby achieving the purpose of surrounding the first mold cavity 213. The first flow channel 214 surrounds the first mold body 211 one or more times, thereby achieving the purpose of surrounding the first cavity one or more times. In this embodiment, the first mold cover 212 is configured as a special-shaped cover, and a groove structure (not shown) is formed in the first mold cover 212. When the first mold cover 212 covers the first mold body 211, the first flow channel 214 is formed outside the first mold body 211. In this case, the first flow channel 214 is located between the first mold cover 212 and the first mold body 211. At the same time, when the wall thickness of the first mold cavity 213 is uniform, the energy in the first flow channel 214 surrounding the outside of the first mold body 211 can be evenly transferred to the first mold cavity 213 through the first mold body 211, thereby achieving more uniform freezing of the ice-making cavity 230 and more uniform thawing during the thawing process, resulting in more complete ice after thawing.

[0330] However, the present design is not limited to this. In other embodiments, the first mold 210 may also adopt other structures. For example, the first mold 210 may only include the first mold body 211. In this case, the first flow channel 214 is formed on the outside of the first mold body 211. Specifically, a pipeline (not shown) is fixed to the outside of the first mold body 211, and the first flow channel 214 is set in the pipeline, wherein the pipeline can be set around the outside of the first mold body 211 in one or more circles.

[0331] In one embodiment, the second mold 220 is provided with a second flow channel (not shown) for the circulation of a thawing medium. When the temperature of the introduced refrigerant is high, the refrigerant can thaw the ice and the wall of the second mold cavity 223 .

[0332] In one embodiment, the second flow channel includes multiple circles of flow channels (not shown) connected in sequence in a direction away from the first mold 210 , and the multiple circles of flow channels in the second flow channel are similar or identical in structure to the multiple circles of flow channels 2141 in the first flow channel 214 .

[0333] In the first embodiment, referring to Figures 51 and 52, the second mold 220 includes a second mold body 221 and a second mold cover 222. The second mold cover 222 is disposed to cover the second mold body 221. The second mold cavity 223 is formed on a side of the second mold body 221 facing away from the second mold cover 222. The second flow channel is disposed between the second mold body 221 and the second mold cover 222. In this embodiment, the second mold cover 222 is configured as a special-shaped cover and has a groove structure (not shown) formed therein. When the second mold cover 222 covers the second mold body 221, the second flow channel is formed outside the second mold body 221. In this case, the second flow channel is located between the second mold cover 222 and the second mold body 221.

[0334] However, the present design is not limited to this. In other embodiments, the second mold 220 may also adopt other structures. For example, the second mold 220 may only include the second mold body 221. In this case, the second flow channel is formed on the outside of the second mold body 221. Specifically, a pipeline (not shown) is fixed to the outside of the second mold body 221, and the second flow channel is arranged in the pipeline, wherein the pipeline can be arranged around the outside of the second mold body 221 in one or more circles.

[0335] In one embodiment, the walls of the second mold cavity 223 are of uniform or nearly uniform thickness. Referring to FIG. 59 , when the walls of the second mold cavity 223 are of uniform thickness, energy in the second flow channel surrounding the exterior of the second mold body 221 can be uniformly transferred through the second mold body 221 to the second mold cavity 223, thereby achieving more uniform freezing of the ice-making cavity 230 or more uniform thawing during thawing, resulting in a more complete ice body after thawing. The ice-making machine further includes a heating element 500 covering the back surface of the wall of the second mold cavity 223. In this embodiment, when the second mold 220 only includes the second mold body 221, the back side of the cavity wall of the second mold cavity 223 is the outer surface of the second mold body 221; further, when the ice body and the cavity wall of the second mold cavity 223 are thawed by the heating element 500, the heating element 500 can be configured as a heating film, which generates heat through the heating element 500 and transfers the heat to the second mold cavity 223 through the second mold body 221, so as to melt and thaw the ice body and the cavity wall of the second mold cavity 223.

[0336] In one embodiment, referring to Figure 52, the heating element 500 can adopt the following structure, wherein the heating element 500 includes a flexible body 510 covering the back side of the cavity wall of the second mold cavity 223, and a heating element (not shown) embedded in the flexible body 510. In this embodiment, by heating the heating element, the heat generated by the heating element is transferred to the cavity wall of the second mold cavity 223 through the flexible body 510 and the second mold body 221, so as to melt and thaw the ice body and the cavity wall of the second mold cavity 223. In this embodiment, the heating element can be a heating wire.

[0337] In one embodiment, the flexible body 510 is configured as a silicone body, and the silicone body to be used is a silicone body that can withstand high temperatures, at least about 150°C; however, the present design is not limited to this. In other embodiments, the flexible body 510 can also be configured as a foil-like or thin sheet-like metal body, as long as it has a certain degree of bending flexibility and a certain degree of thermal conductivity.

[0338] In one embodiment, referring to Figure 52, the flexible body 510 includes a plurality of flexible petals 511 arranged in sequence in the circumferential direction of the second mold 220, and the plurality of flexible petals 511 jointly cover the back side of the cavity wall of the second mold cavity 223. When the second mold 220 only includes the second mold body 221, the back side of the cavity wall of the second mold cavity 223 is the outer surface of the second mold body 221.

[0339] In one embodiment, the ice maker further includes an ejector (not shown) and a drive member (not shown). The ejector is movably mounted on the second mold 220 and can be movably extended into the second mold cavity 223. The drive member is drivably connected to the ejector. When ice making is complete, the ejector can eject the ice from the wall of the second mold cavity 223 to thaw the ice. In this embodiment, the drive member can be configured as an electric telescopic rod, and the ejector can be configured as an ejector tube. The second mold body 221 is provided with a mounting slot, and the ejector tube is disposed in the mounting slot. A seal is provided between the ejector tube and the mounting slot of the second mold body 221. During the ice making process, the ejector tube is located in the mounting slot. When ice making is complete, the electric telescopic rod ejects the ejector tube from the mounting slot, ejecting the ice in the second mold cavity 223 through the ejector tube, thereby thawing the ice in the second mold cavity 223 and the wall. In this embodiment, the drive member can also be configured as a cylinder assembly.

[0340] In one embodiment, referring to Figures 53 to 57 , the ice maker further includes a spray assembly 400. The spray assembly 400 includes a mounting base 410 having a water inlet channel 420 and a spray hole 430, and a flow guide 440 mounted to the spray hole 430. The mounting base 410 is mounted to the second mold 220. The water inlet channel 420 is used to supply water, and the flow guide 440 is used to disperse the water sprayed through the spray hole 430. In this embodiment, the second mold 220 is provided with a mounting hole 224 for mounting the mounting base 410, and the mounting base 410 is fixed to the mounting hole 224. When the spray assembly 400 sprays water toward the ice-making chamber 230, water enters through the water inlet channel 420 and is then sprayed toward the ice-making chamber 230 through the spray hole 430. Since a guide member 440 is provided in the water inlet channel 420, the water sprayed through the spray hole 430 is dispersed. In this way, water spraying at multiple angles can be achieved, making it convenient to spray the ice-making chamber 230 more evenly, so that the ice-making chamber 230 is condensed into a more even layer of ice.

[0341] In one embodiment, referring to Figures 54, 55, and 56, the return water hole 225 can be set in the mounting seat 410 installed on the second mold 220. Specifically, the return water hole 225 is opened in the mounting seat 410, and one end is connected to the second mold cavity 223, and the other end is connected to the outside of the second mold 220. In this embodiment, when the second mold 220 is set below the first mold 210, the spray assembly 400 installed in the second mold 220 sprays water toward the ice-making cavity 230. The sprayed water is upward. After being sprayed, some of the water that has not condensed in the ice-making cavity 230 will flow downward under the action of gravity and can flow into the return water hole 225. Furthermore, in order to facilitate the use of the return water hole 225, the return water hole 225 is set at a lower position in the second mold cavity 223. In this way, it is convenient for the return water hole 225 to collect uncondensed water. Furthermore, the return hole 225 is integrated into the mounting base 410 of the spray assembly 400, which simplifies the installation process of the present application. After the spray assembly 400 is installed on the second mold 220, its return hole 225 is also installed. In the present application, the return hole 225 is connected to the return water box, and water entering the return hole 225 flows into the return water box.

[0342] In one embodiment, the guide member 440 is configured as a spiral nozzle 441 (see Figures 56 and 57) or a spiral guide blade 442 (see Figures 54 and 55). In this embodiment, when the guide member 440 is configured as a spiral nozzle 441, the water sprayed toward the ice making chamber 230 through the spray hole 430 can be dispersed.

[0343] In this embodiment, when the guide member 440 is configured as a spiral guide blade 442 (see Figure 55), a fluid spiral generating chamber 460 is formed between the spiral guide blade 442 and the spray hole 430, and a conical structure 450 is formed between the fluid spiral generating chamber 460 and the spray hole 430. The spiral guide blade 442 includes a dividing portion 4421 and two guide portions 4422. The two guide portions 4422 are both installed on the dividing portion 4421. The guide portion 4422 is spiral. The cutting portion 4421 is used to divide the water in the water inlet channel 420 into two parts. The two parts of water move spirally along the two guide portions 4422 respectively, enter the fluid spiralization generating chamber 460 to generate spiral flow, and under the action of the conical structure 450, the spirally moving water can better flow to the spray hole 430. At this time, the water sprayed from the spray hole 430 can be dispersed, thereby realizing multi-angle water spraying, facilitating more uniform spraying in the ice-making chamber 230, so that a more uniform condensation of ice layer is formed on the ice-making chamber 230.

[0344] In one embodiment, referring to Figures 52 and 53, the first mold 210 is further provided with an exhaust hole 260, and the first mold 210 is arranged above the second mold 220; during the ice-making process, when the spray assembly 400 sprays water onto the cavity wall of the ice-making chamber 230, the cavity wall can cool the water flow under the action of the refrigerant, so that the water flow can condense on the cavity wall of the ice-making chamber 230. During the condensation process, the air between the water flow and the cavity wall of the ice-making chamber 230 can be discharged through the exhaust hole 260, thereby conveniently discharging the air in the ice-making chamber 230.

[0345] In one embodiment, in order to collect uncondensed water or discharge gas in the ice-making chamber 230, the second mold 220 is further provided with a water return hole (not shown). When the second mold 220 includes a second mold body 221, the water return hole can be provided on the second mold body 221.

[0346] In one embodiment, referring to Figures 50, 51, and 52, the drive assembly 300 includes a worm 310, a worm housing 320, a drive motor 330, and a guide rod 340. The worm 310 is mounted on the frame 100. The worm housing 320 is movably mounted on the worm 310 and fixed to the second mold 220. The drive motor 330 is drivingly connected to the worm 310. The second mold 220 is slidably engaged with the guide rod 340, and the guide rod 340 is fixed to the frame 100. Specifically, the drive motor 330 drives the worm 310 to rotate. At this time, the worm housing 320, which is movably mounted on the worm 310, can move up and down along the worm 310. When the worm 310 moves up and down, it can drive the second mold 220 to move in a straight line. When the second mold 220 moves in a straight line, it can slide along the guide rod 340, thereby achieving the purpose of the drive structure 630 driving the second mold 220 to move in a straight line. The drive assembly 300 further includes a synchronous belt 370 and a plurality of synchronous pulleys 380 (see FIG50 ). The plurality of synchronous pulleys 380 are mounted on the worm 310 and the output end of the drive motor 330. Furthermore, the output end of the drive motor 330 is connected to the synchronous pulleys 380 via a differential. The synchronous belt 370 connects the plurality of synchronous pulleys 380. When the drive motor 330 rotates, the synchronous pulleys 380 and the synchronous belt 370 drive the worm 310 to rotate. Furthermore, in this embodiment, the worm 310 and the worm housing 320 are each configured in two sets. The two sets of worms 310 are respectively disposed on either side of the second mold 220, and the two sets of worm housings 320 are both fixed to the second mold 220. The driving motor 330 is connected to the two sets of worm gears 310 through a synchronous belt 370 and a synchronous wheel 380. Specifically, synchronous wheels 380 are provided on the output ends of the two sets of worm gears 310 and the driving motor 330. The synchronous belt 370 connects the three synchronous wheels 380. At this time, the output end of the driving motor 330 rotates, and the synchronous wheel 380 and the synchronous belt 370 can drive the two sets of worm gears 310 to rotate simultaneously, thereby realizing the straight line movement of the second mold 220.

[0347] However, the present design is not limited thereto. In other embodiments, the driving assembly 300 may also be configured as a cylinder assembly, an electric telescopic component, etc.

[0348] Furthermore, the drawings of this application illustrate an embodiment in which the second mold 220 is positioned below the first mold 210. However, the present design is not limited thereto; in other embodiments, the second mold 220 may be positioned above the first mold 210. When the first mold 210 and the second mold 220 are positioned vertically, the second mold 220 moves in a vertically aligned direction.

[0349] However, the present design is not limited thereto. In other embodiments, the first mold 210 and the second mold 220 may be arranged horizontally. In this case, the second mold 220 moves along a horizontal straight line.

[0350] In one embodiment, when the first mold 210 and the second mold 220 are distributed up and down, referring to Figures 58 to 61, the ice making machine in this application also includes an ice guide structure 600, which includes an ice guide plate, and the ice guide plate is used to guide the ice body out of the ice making machine. Specifically, when the second mold 220 is located below the first mold 210, at this time, it is necessary to first thaw the ice body and the cavity wall of the second mold cavity 223 through a thawing medium. After the ice body and the cavity wall of the second mold cavity 223 are thawed, the driving component 300 drives the second mold 220 to move to the second position. After the second mold 220 moves to the second position, the ice guide structure 600 enters between the first mold 210 and the second mold 220. After the ice guide structure 600 is located between the first mold 210 and the second mold 220, the heat medium is passed into the first flow channel 214. At this time, the ice body and the inner wall of the first mold cavity 213 are thawed. The thawed ice body can fall into the ice guide structure 600 located below the first mold 210, and the ice guide structure 600 now guides the ice body out. Similarly, when the second mold 220 is located above the first mold 210, it is necessary to first introduce heat medium to thaw the ice body and the inner wall of the first curtain wall. At this time, the driving component 300 drives the second mold cavity 223 and the ice body to move to the second position. After the second mold 220 moves to the second position, the ice guide plate enters between the first mold 210 and the second mold 220, and then the thawing medium thaws the ice body and the cavity wall of the second mold cavity 223. At this time, the ice body can fall into the ice guide plate located below the second mold 220, and the ice guide plate guides the ice body out. In this embodiment, the ice guide plate is configured as a whole plate.

[0351] In one embodiment, referring to Figures 58 to 61 , the ice guide plate can have the following structure. Specifically, the ice guide plate includes a first ice guide plate 610 and a second ice guide plate 620. The ice guide structure 600 has a first state and a second state. When the ice-making chamber 230 is making ice, the ice guide structure 600 is in the first state. In the first state, the first ice guide plate 610 and the second ice guide plate 620 are respectively located on either side of the mold assembly 200. When the second mold 220 is in the second position, the ice guide structure 600 is in the second state. In the second state, the first ice guide plate 610 and the second ice guide plate 620 are located between the first mold 210 and the second mold 220. In this state, the first ice guide plate 610 and the second ice guide plate 620 can form an inclined ice guide structure 600. Furthermore, the second ice guide plate 620 is located above the first ice guide plate 610. At the same time, when the second mold 220 moves from the first position to the second position, the ice guide structure 600 gradually switches from the first state to the second state. At this time, the first ice guide plate 610 and the second ice guide plate 620 are gradually tilted from being set on both sides of the mold assembly 200 to between the first mold 210 and the second mold 220. In this embodiment, the ice guide structure 600 also includes a driving structure 630, wherein the driving structure 630 includes a first swing arm 631 and a second swing arm 632, the first swing arm 631 and the second swing arm 632 are both rotatably connected to the frame 100, the first ice guide plate 610 is fixed to the first swing arm 631, the second ice guide plate 620 is fixed to the second swing arm 632, and a torsion spring 633 is provided between the first ice guide plate 610 and the second ice guide plate 620 and the frame 100. Under the action of the torsion spring 633, the first ice guide plate 610 and the second ice guide plate 620 can be located outside the mold assembly 200, that is, the ice guide structure 600 is in the first state; further, the driving structure 630 also includes a driving plate 634 and a transmission member 635, specifically, the driving plate 634 is fixed to the second mold 220, wherein, The driving plate 634 is arranged on the outside of the frame 100, and a guide slot 110 is opened on the frame 100. Part of the structure of the driving plate 634 passes through the guide slot 110 and is fixed to the second mold 220, wherein the driving plate 634 is fixed to the second mold body 221 in the second mold 220. When the driving component 300 drives the second mold 220 to move in a straight line, the driving plate 634 can follow the second mold 220 to move in a straight line. Furthermore, the first swing arm 631 is set near the second position of the second mold 220. When the driving component 300 drives the second mold 220 to be in the second position, the driving plate 634 can press down the first swing arm 631, causing the first swing arm 631 to swing, thereby driving the first ice guide plate 610 to flip, so that the first ice guide plate 610 is located between the first mold 210 and the second mold 220.Furthermore, the transmission member 635 includes a transmission gear 6351, a driving tooth 6352 provided on the driving plate 634, and a third swing arm 6353, wherein the transmission gear 6351 and the third swing arm 6353 are both installed on the frame 100, and the third swing arm 6353 and the transmission gear 6351 are meshed. That is, the third swing arm 6353 is provided with a driven gear 6354 that cooperates with the transmission gear 6351. Specifically, when the transmission gear 6351 rotates, the third swing arm 6353 can swing under the action of the driven gear 6354, and the third swing arm 6353 is drivingly connected to the second swing arm 632. When the third swing arm 6353 swings, the third swing arm 6353 can drive the second swing arm 632 to swing, and the second swing arm 632 swings to realize the flipping of the second ice guide plate 620, so that the second ice guide plate 620 is located between the first mold 210 and the second mold 220. In this embodiment, when the driving plate 634 moves along with the second mold 220 from the first position to a position close to the second position, the driving teeth 6352 on the driving plate 634 can engage with the transmission gear 6351. As the driving plate 634 continues to move toward the second position, the transmission gear 6351 rotates. When the transmission gear 6351 rotates, it drives the third swing arm 6353 to swing, so that the third swing arm 6353 drives the second swing arm 632 to swing, thereby realizing the flipping of the second ice deflector 620, so that the second ice deflector 620 is located between the first mold 210 and the second mold 220. When the driving plate 634 follows the second mold 220 to move from the second position to the first position, the driving tooth 6352 drives the transmission gear 6351 to rotate, thereby causing the third swing arm 6353 to return to its initial position. At this time, the second ice guide plate 620 returns to its initial state under the action of the torsion spring 633, thereby being located outside the mold assembly 200. At the same time, the driving plate 634 does not press down the first swing arm 631, and the first ice guide plate 610 also returns to its initial state under the action of the torsion spring 633, thereby being located outside the mold assembly 200.
