[0056] When making ice, water needs to be injected into the ice-making mold, and then the mold is cooled so that the water in the mold freezes into ice. After the water freezes into ice, the ice-making mold is opened. Existing ice-making molds have the problem of low automation during the mold-opening process.

[0057] At the same time, existing ice-making molds also have a slow energy transfer during the ice-making process. When the energy transfer is slow, during the ice-making process, the time required to freeze water into ice is longer, and the time required to demold the ice after ice-making is also longer.

[0058] The present utility model proposes an ice maker.

[0059] Please refer to Figure 1 、 Figure 11 、 Figure 12 、 Figure 13 In an embodiment of the present utility model, the ice maker includes:

[0060] A frame 100;

[0061] A mold assembly 200, including a first mold 210 and a second mold 220. The first mold 210 is fixedly arranged on the frame 100 and has at least one first mold cavity 213. The second mold 220 is movably installed on the frame 100 and has at least one second mold cavity 223; and

[0062] A driving assembly 300, installed on the frame 100 and drivingly connected to the second mold 220, capable of driving the second mold 220 to move linearly so that the second mold 220 has a first position (see Figure 10 、 Figure 11 ) closed relative to the first mold 210 and a second position (see Figure 12 、 Figure 13 ) opened 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 combined with the first mold 210, and the first mold cavity 213 and the second mold cavity 223 form an ice-making cavity 230 for making ice, and one first mold cavity 213 and one second mold cavity 223 are correspondingly arranged; when the number of the first mold cavities 213 and the second mold cavities 223 is set to one, the number of the ice-making cavities 230 is one; when the number of the first mold cavities 213 and the second mold cavities 223 is set to three, the number of the ice-making cavities 230 is also three; after ice-making is completed, when the driving assembly 300 drives the second mold 220 to the second position, the ice can be separated from the mold assembly 200.

[0063] The first mold 210 is provided with a first flow channel 214 for the refrigerant to flow through. The first flow channel 214 includes multiple turns of flow channels 2141 that are sequentially connected in a direction away from the second mold 220. Specifically, the multiple turns of flow channels 2141 are arranged around the first mold cavity 213, that is, the first flow channel 214 is arranged around the first mold cavity 213. In this embodiment, the first mold 210 can have different effects according to the temperature of the refrigerant introduced into the first flow channel 214. When the temperature of the introduced refrigerant is relatively low, the refrigerant freezes the water in the ice-making cavity 230. When the temperature of the introduced refrigerant is relatively high, the refrigerant can thaw the ice body and the cavity wall of the first mold cavity 213.

[0064] In this embodiment, since the first flow channel 214 includes multiple turns of flow channels 2141 (see Figure 5 , Figure 11 , Figure 13 ) that are sequentially connected 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 turns of flow channels 2141. At this time, after the refrigerant is introduced into the first flow channel 214, due to the increase in the relative contact area between the first flow channel 214 and the first mold cavity 213, the energy of the refrigerant can be transferred to the ice-making cavity 230 faster, so that the ice-making cavity 230 can be cooled rapidly, and thus the water in the ice-making cavity 230 can be frozen rapidly.

[0065] In this embodiment, before ice making, the driving component 300 drives the second mold 220 to move linearly, so that the second mold 220 moves to the first position. At this time, the second mold 220 is combined with the first mold 210, and the first mold cavity 213 and the second mold cavity 223 form an ice-making cavity 230. After the ice-making cavity 230 is formed, water is injected into the ice-making cavity 230, and then the refrigerant is introduced into the first flow channel 214. Or after the ice-making cavity 230 is formed, the refrigerant is introduced into the first flow channel 214, and then water is injected into the ice-making cavity 230. Under the action of the refrigerant, the mold assembly 200 is cooled, and by cooling the mold assembly 200, the water in the ice-making cavity 230 is cooled, so that the water is frozen into ice. After a preset cooling time, the water in the ice-making cavity 230 is frozen into ice. When the water in the ice-making cavity 230 is completely frozen into ice, the driving component 300 drives the second mold 220 to move linearly, so that the second mold 220 moves to the second position. At this time, the second mold 220 is separated from the first mold 210, and the formed ice is in one of the first mold cavity 213 or the second mold cavity 223. When the ice is in the first mold cavity 213, the ice can be removed from the first mold cavity 213. When the ice is in the second mold cavity 223, the ice can be removed from the second mold cavity 223. In this embodiment, there is no limitation on the method of removing the ice from the first mold cavity 213 or the second mold cavity 223. The ice can be removed by directly ejecting the ice from the first mold cavity 213 or the second mold cavity 223. It can also be removed by melting and separating the ice from the cavity wall of the first mold cavity 213 or the cavity wall of the second mold cavity 223 by using a refrigerant with a higher temperature.

[0066] The technical solution of the present utility model drives the second mold 220 to move linearly by using the driving component 300, and the driving component 300 can be configured as a linear driving structure 630; when ice making is required, the driving component 300 drives the second mold 220 to move linearly, so that it moves to the first position. At this time, the second mold 220 is combined 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, so that the water is frozen into ice; after 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 assembly 200 is opened, and then the ice can be removed from the first mold cavity 213 or the second mold cavity 223. In this application, by driving the second mold 220 to move by the driving component 300, the combination and opening of the mold assembly 200 are realized, which can effectively improve the automation degree of the mold opening during the ice-making process of the ice maker, and further solve the technical problems existing in the prior art.

[0067] In one embodiment, for any annular flow channel 2141 in the middle, the connection points (not shown) between it and the adjacent annular flow channels 2141 close to the second mold 220, and the connection points between it and the adjacent annular flow channels 2141 far from the second mold 220 are located on opposite sides of this annular flow channel 2141. That is to say, after the refrigerant enters the first flow channel 214, it first enters the upper-layer flow channels 2141, then flows along the upper-layer flow channels 2141 to the connection points. At this time, it enters the middle-layer flow channels 2141 through the connection points, and then flows along the middle-layer flow channels 2141 to the connection points. At this time, it flows into the lower-layer flow channels 2141 through the connection points between the middle-layer flow channels 2141 and the lower-layer flow channels 2141. At this time, the flow direction of the refrigerant in the upper-layer flow channels 2141 is opposite to that in the lower-layer flow channels 2141. In this way, it can prevent the refrigerant from directly entering the middle-layer and lower-layer flow channels 2141 from the upper-layer flow channels 2141, improve the flow path of the refrigerant in the first flow channel 214, and further increase the relative contact area between the refrigerant and the first mold cavity 213.

[0068] In one embodiment, the first mold 210 may adopt the following structure. Refer to Figure 3 , Figure 4 , Figure 5 , the first mold 210 includes a first mold body 211 and a first mold cover 212. The first mold cover 212 is disposed to cover the first mold body 211. 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, by forming the first flow channel 214 between the first mold cover 212 and the first mold body 211, it is arranged to surround the first mold body 211, so as to achieve the purpose of surrounding the first mold cavity 213. The first flow channel 214 surrounds the first mold body 211 for one or more turns, and further realizes that the first flow channel 214 surrounds the first cavity for one or more turns. 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 can be formed outside the first mold body 211. At this time, 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 thickness of the cavity wall of the first mold cavity 213 is the same, the energy in the first flow channel 214 surrounding the outside of the first mold body 211 can be evenly transmitted to the first mold cavity 213 through the first mold body 211, so as to make the ice-making cavity 230 more uniform during freezing, or during the thawing process, the thawing is more uniform, and the ice body after thawing is more complete.

[0069] However, the present design is not limited thereto. 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. At this time, the first runner 214 is formed on the outside of the first mold body 211. Specifically, a pipeline (not shown) is fixedly provided outside the first mold body 211, and the first runner 214 is arranged in the pipeline, and the pipeline may be arranged around the outside of the first mold body 211 for one or more turns.

[0070] In one embodiment, the second mold 220 is provided with a second runner (not shown) for the thawing medium to flow through. When the temperature of the refrigerant introduced is relatively high, the refrigerant can thaw the ice body and the cavity wall of the second cavity 223.

[0071] In one embodiment, the second runner includes multiple turns of runners (not shown) that are sequentially connected in the direction away from the first mold 210. The multiple turns of runners in the second runner are similar or identical in structure to the multiple turns of runners 2141 in the first runner 214.

[0072] In the first embodiment, refer to Figure 3 、 Figure 4 , the second mold 220 includes a second mold body 221 and a second mold cover 222. The second mold cover 222 is arranged to cover the second mold body 221. The second cavity 223 is formed on the side of the second mold body 221 facing away from the second mold cover 222. The second runner is arranged 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 a groove structure (not shown) is formed in the second mold cover 222. When the second mold cover 222 covers the second mold body 221, the second runner can be formed on the outside of the second mold body 221. At this time, the second runner is located between the second mold cover 222 and the second mold body 221.

[0073] However, the present design is not limited thereto. 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. At this time, the second runner is formed on the outside of the second mold body 221. Specifically, a pipeline (not shown) is fixedly provided outside the second mold body 221, and the second runner is arranged in the pipeline, and the pipeline may be arranged around the outside of the second mold body 221 for one or more turns.

[0074] In one embodiment, the cavity wall of the second cavity 223 is set to be of equal thickness or nearly equal thickness. Refer to Figure 11, meanwhile, when the thickness of the cavity wall of the second mold cavity 223 is the same, the energy in the second flow channel surrounding the outside of the second mold body 221 can be evenly transferred to the second mold cavity 223 through the second mold body 221, so as to make the ice-making cavity 230 more uniform during freezing, or during the thawing process, the thawing is more uniform, making the ice body after thawing more complete. The ice maker further includes a heating element 500 covering the back surface of the cavity wall of the second mold cavity 223. In this embodiment, when the second mold 220 only includes the second mold body 221, the back surface of the cavity wall of the second mold cavity 223 is the outer surface of the second mold body 221; further, when thawing the ice body and the cavity wall of the second mold cavity 223 through the heating element 500, the heating element 500 can be configured as a heating film, and by heating the heating element 500, the heat is transferred to the second mold cavity 223 through the second mold body 221, so as to thaw and melt the ice body and the cavity wall of the second mold cavity 223.

[0075] In one embodiment, referring to Figure 4 , the heating element 500 can adopt the following structure. The heating element 500 includes a flexible body 510 covering the back surface of the cavity wall of the second mold cavity 223 and a heating body (not shown) embedded in the flexible body 510. In this embodiment, by heating the heating body, the heat generated by the heating body 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 thaw and melt the ice body and the cavity wall of the second mold cavity 223. In this embodiment, the heating body can be selected as a heating wire.

[0076] In one embodiment, the flexible body 510 is configured as a silica gel body, and the silica gel body to be used is a silica gel body that can withstand high temperatures, and can at least withstand high temperatures of about 150 °C; however, this design is not limited thereto. In other embodiments, the flexible body 510 can also be configured as a foil-shaped or sheet-shaped metal body, as long as it has a certain bending flexibility and a certain heat conduction ability.

[0077] In one embodiment, referring to Figure 4 , the flexible body 510 includes a plurality of flexible flaps 511 arranged in sequence in the circumferential direction of the second mold 220. The plurality of flexible flaps 511 jointly cover the back surface of the cavity wall of the second mold cavity 223. When the second mold 220 only includes the second mold body 221, the back surface of the cavity wall of the second mold cavity 223 is the outer surface of the second mold body 221.

[0078] In one embodiment, the ice maker further includes an ejector (not shown) and a driving member (not shown). The ejector is movably installed in the second mold 220, and the ejector can movably extend into the second mold cavity 223. The driving member is drivingly connected to the ejector. After ice making is completed, the ejector can thaw the ice body and the cavity wall of the second mold cavity 223 in an ejecting manner. In this embodiment, the driving member can be configured as an electric telescopic rod, and the ejector is configured as an ejecting tube. An installation groove is provided in the second mold body 221, the ejecting tube is arranged in the installation groove, and a sealing member is provided between the ejecting tube and the installation groove of the second mold body 221. During the ice making process, the ejecting tube is located in the installation groove. After ice making is completed, the electric telescopic rod ejects the ejecting tube from the installation groove, and the ice body in the second mold cavity 223 is ejected through the ejecting tube, thereby realizing the thawing of the ice body in the second mold cavity 223 and the cavity wall. In this embodiment, the structure of the driving member can also be configured as a cylinder assembly.

[0079] In one embodiment, referring to Figures 5 to 9 , the ice maker further includes a spraying assembly 400. The spraying assembly 400 includes a mounting seat 410 provided with a water inlet flow channel 420 and spraying holes 430, and a flow guiding member 440 installed in the spraying holes 430. The mounting seat 410 is installed on the second mold 220. The water inlet flow channel 420 is used for water input, and the flow guiding member 440 is used to make the water sprayed out through the spraying holes 430 be in a dispersed state. In this embodiment, the second mold 220 is provided with a mounting hole 224 for installing the mounting seat 410, and the mounting seat 410 is fixedly arranged in the mounting hole 224. When the spraying assembly 400 sprays water towards the ice making cavity 230, the water enters through the water inlet flow channel 420 and then is sprayed towards the ice making cavity 230 through the spraying holes 430. Since the flow guiding member 440 is arranged in the water inlet flow channel 420, the water sprayed out through the spraying holes 430 is in a dispersed state. In this way, multi-angle spraying can be realized, which is convenient for relatively uniform spraying inside the ice making cavity 230, so that an ice layer is relatively uniformly condensed on the ice making cavity 230.

[0080] In one embodiment, referring to Figure 6 , Figure 7 , Figure 8, the water return hole 225 can be arranged in the mounting seat 410 mounted on the second mold 220. Specifically, the water return hole 225 is opened in the mounting seat 410, one end of which communicates with the second mold cavity 223, and the other end communicates with the outside of the second mold 220. In this embodiment, when the second mold 220 is arranged below the first mold 210, at this time, when the spraying assembly 400 mounted in the second mold 220 sprays water into the ice making cavity 230, the sprayed water is upward. After spraying, part of the water that has not condensed in the ice making cavity 230 will flow downward under the action of gravity, and at this time, it can flow into the water return hole 225. Further, in order to facilitate the use of the water return hole 225, the water return hole 225 is arranged at a lower position in the second mold cavity 223. In this way, it is convenient for the water return hole 225 to collect the uncondensed water. Further, the water return hole 225 is integrated on the mounting seat 410 of the spraying assembly 400, which can simplify the installation process of the present application. After the spraying assembly 400 is mounted on the second mold 220, its water return hole 225 is also mounted. In the present application, the water return hole 225 communicates with the water return box, and the water entering the water return hole 225 flows into the water return box.

[0081] In one embodiment, the deflector 440 is configured as a spiral nozzle 441 (see Figure 8 , Figure 9 ) or a spiralized deflector vane 442 ( Figure 6 , Figure 7 ). In this embodiment, when the deflector 440 is configured as the spiral nozzle 441, the water sprayed toward the ice making cavity 230 through the spray holes 430 can be in a dispersed state.

[0082] In this embodiment, when the deflector 440 is configured as the spiralized deflector vane 442 (see Figure 7 ), a fluid spiralization generation cavity 460 is formed between the spiralized deflector vane 442 and the spray holes 430, and a conical structure 450 is formed between the fluid spiralization generation cavity 460 and the spray holes 430. The spiralized deflector vane 442 includes a dividing part 4421 and two deflector parts 4422. Both of the deflector parts 4422 are mounted on the dividing part 4421. The deflector parts 4422 are in a spiral shape. The dividing part 4421 is used to divide the water in the water inlet channel 420 into two parts, and the two parts of water respectively move spirally along the two deflector parts 4422 and enter the fluid spiralization generation cavity 460 to generate spiral flow. Under the action of the conical structure 450, the spirally moving water can flow better to the spray holes 430, and at this time, the water sprayed from the spray holes 430 can be in a dispersed state, so as to realize multi-angle water spraying, which is convenient for relatively uniform spraying inside the ice making cavity 230, so that an ice layer is relatively uniformly condensed on the ice making cavity 230.

[0083] In one embodiment, refer to Figure 4, Figure 5 The first mold 210 is further provided with an exhaust hole 260, and the first mold 210 is disposed above the second mold 220. During the ice-making process, when the spraying assembly 400 sprays water onto the cavity wall of the ice-making cavity 230, the cavity wall can cool and 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 cavity 230. During the condensation process, the air between the water flow and the cavity wall of the ice-making cavity 230 can be discharged through the exhaust hole 260, thereby facilitating the discharge of the air in the ice-making cavity 230.

[0084] In an embodiment, in order to collect the uncondensed water or discharge the gas in the ice-making cavity 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, its water return hole can be provided on the second mold body 221.

[0085] In an embodiment, referring to Figure 2 , Figure 3 , Figure 4 , the driving assembly 300 includes a worm 310, a worm sleeve 320, a driving motor 330, and a guide rod 340. The worm 310 is installed on the frame 100. The worm sleeve 320 is movably installed on the worm 310 and is fixedly provided with the second mold 220. The driving 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 fixedly provided on the frame 100. Specifically, by driving the worm 310 to rotate by the driving motor 330, the worm sleeve 320 movably installed 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 linearly. When the second mold 220 moves linearly, it can slide along the guide rod 340, thereby achieving the purpose of driving the second mold 220 to move linearly by the driving structure 630. The driving assembly 300 further includes a synchronous belt 370 and a plurality of synchronous wheels 380 (see Figure 2) Multiple of the synchronous pulleys 380 are installed at the output ends of the worm 310 and the drive motor 330. Further, the output end of the drive motor 330 is connected to the synchronous pulley 380 through a differential. The synchronous belt 370 connects multiple of the synchronous pulleys 380. When the drive motor 330 rotates, the worm 310 can be driven to rotate through the synchronous pulley 380 and the synchronous belt 370. Further, in this embodiment, both the worm 310 and the worm sleeve 320 are configured in two groups. The two groups of worms 310 are respectively arranged on both sides of the second mold 220, and both groups of worm sleeves 320 are fixedly arranged with the second mold 220. The drive motor 330 is drivingly connected to the two groups of worms 310 through the synchronous belt 370 and the synchronous pulley 380. Specifically, synchronous pulleys 380 are arranged on both the two groups of worms 310 and the output end of the drive motor 330, and the synchronous belt 370 connects three synchronous pulleys 380. At this time, when the output end of the drive motor 330 rotates, the two groups of worms 310 can be driven to rotate simultaneously through the synchronous pulley 380 and the synchronous belt 370, thereby realizing the linear movement of the second mold 220.

[0086] However, this design is not limited thereto. In other embodiments, the drive assembly 300 can also be configured as a cylinder assembly, an electric telescopic member, etc.

[0087] Further, in the drawings of the present application, an embodiment is given in which the second mold 220 is arranged below the first mold 210. However, this design is not limited thereto. In other embodiments, the second mold 220 can be arranged above the first mold 210. When the first mold 210 and the second mold 220 are vertically distributed, the second mold 220 moves along a vertical straight line direction.

[0088] However, this design is still not limited thereto. In other embodiments, the first mold 210 and the second mold 220 can be horizontally arranged. At this time, the second mold 220 moves along a horizontal straight line direction.

[0089] In one embodiment, when the first mold 210 and the second mold 220 are vertically distributed, refer to Figures 10 to 13, the ice maker in the present application further includes an ice guiding structure 600, and the ice guiding structure includes an ice guiding plate for guiding the ice body out of the ice maker. 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 assembly 300 drives the second mold 220 to move to the second position. After the second mold 220 moves to the second position, the ice guiding structure 600 enters between the first mold 210 and the second mold 220. After the ice guiding structure 600 is located between the first mold 210 and the second mold 220, the heat medium is introduced into the first flow channel 214. At this time, the ice body and the inner wall of the first mold cavity 213 are completely thawed, and the thawed ice body can fall into the ice guiding structure 600 located below the first mold 210. At this time, the ice guiding structure 600 guides the ice body out. Similarly, when the second mold 220 is located above the first mold 210, it is necessary to first introduce the heat medium to completely thaw the ice body and the inner wall of the first curtain wall. At this time, the driving assembly 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 guiding plate enters between the first mold 210 and the second mold 220. 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 guiding plate located below the second mold 220, and the ice guiding plate guides the ice body out. In this embodiment, the ice guiding plate is configured as a whole plate.

[0090] In one embodiment, refer to Figures 10 to 13, the ice guide plate can adopt the following structure. Specifically, the ice guide plate includes a first ice guide plate 610 and a second ice guide plate 620. The ice guiding structure 600 has a first state and a second state. When the ice making chamber 230 is making ice, the ice guiding 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 both sides of the mold assembly 200. When the second mold 220 is in the second position, the ice guiding 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 between the first mold 210 and the second mold 220. At this time, the first ice guide plate 610 and the second ice guide plate 620 can form an inclined ice guiding structure 600. Further, 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 guiding 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 gradually incline from being arranged on both sides of the mold assembly 200 to between the first mold 210 and the second mold 220. In this embodiment, the ice guiding structure 600 further includes a driving structure 630. The driving structure 630 includes a first swing arm 631 and a second swing arm 632. Both the first swing arm 631 and the second swing arm 632 are rotatably connected to the frame 100. The first ice guide plate 610 is fixed to the first swing arm 631, and the second ice guide plate 620 is fixed to the second swing arm 632. A torsion spring 633 is provided between both 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 both located outside the mold assembly 200, that is, the ice guiding structure 600 is in the first state. Further, the driving structure 630 further includes a driving plate 634 and a transmission member 635. Specifically, the driving plate 634 is fixed to the second mold 220. Among them, the driving plate 634 is arranged outside the frame 100. A guiding chute 110 is formed on the frame 100. A part of the driving plate 634 passes through the guiding chute 110 and is fixed to the second mold 220. The driving plate 634 is fixed to the second mold body 221 in the second mold 220. When the driving assembly 300 drives the second mold 220 to move linearly, the driving plate 634 can move linearly following the second mold 220. Further, the first swing arm 631 is arranged near the second position of the second mold 220. When the driving assembly 300 drives the second mold 220 to be in the second position, at this time the driving plate 634 can press down the first swing arm 631 to make the first swing arm 631 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.Further, 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. The transmission gear 6351 and the third swing arm 6353 are both installed on the frame 100. The third swing arm 6353 meshes with the transmission gear 6351. That is to say, a driven gear 6354 is provided on the third swing arm 6353 to cooperate 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. 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. The second swing arm 632 swings to further realize the flipping of the second ice guiding plate 620, so that the second ice guiding plate 620 is located between the first mold 210 and the second mold 220. In this embodiment, when the driving plate 634 follows the second mold 220 and moves from the first position to near the second position, the driving tooth 6352 on the driving plate 634 can mesh with the transmission gear 6351. As the driving plate 634 continues to move toward the second position, the transmission gear 6351 is driven to rotate. When the transmission gear 6351 rotates, the third swing arm 6353 is driven to swing, so that the third swing arm 6353 drives the second swing arm 632 to swing, so as to realize the flipping of the second ice guiding plate 620, so that the second ice guiding plate 620 is located between the first mold 210 and the second mold 220. When the driving plate 634 follows the second mold 220 and moves from the second position to the first position, at this time, the driving tooth 6352 drives the transmission gear 6351 to rotate, so that the third swing arm 6353 returns to the initial position. At this time, the second ice guiding plate 620 returns to the initial state under the action of the torsion spring 633, so as to be 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 guiding plate 610 also returns to the initial state under the action of the torsion spring 633, so as to be located outside the mold assembly 200.

Specifically, the ice guiding structure 600 is arranged below the first mold 210 and the second mold 220. After the ice making is completed, after the ice body thaws from the cavity walls of the first mold cavity 213 and the second mold cavity 223, the ice body falls onto the ice guiding structure 600 arranged below the first mold 210 and the second mold 220, and then is exported by the ice guiding structure 600. At the same time, in this embodiment, since the ice guiding structure 600 is arranged below the first mold 210 and the second mold 220, at this time, after the ice making is completed, before the driving assembly 300 drives the second mold 220 to move, the ice body can thaw from the cavity wall of the first mold cavity 213 first, or thaw from the cavity wall of the second mold cavity 223 first, which is not limited here.

[0092] In one embodiment, when the first mold 210 and the second mold 220 are horizontally distributed, the ice maker in the present application may not be provided with an ice guiding structure 600, but an ice storage box (not shown) may be provided. Specifically, the ice storage box is arranged below the first mold 210 and the second mold 220. After ice making is completed, after the ice body thaws from the cavity walls of the first mold cavity 213 and the second mold cavity 223, the ice body falls into the ice storage box arranged below the first mold 210 and the second mold 220. At the same time, in this embodiment, since the ice storage box is arranged below the first mold 210 and the second mold 220, at this time, after ice making is completed, before the driving assembly 300 drives the second mold 220 to move, the ice body can thaw from the cavity wall of the first mold cavity 213 first, or thaw from the cavity wall of the second mold cavity 223 first, and there is no limitation here.

The first medium-passing pipe group 700 is used to pass refrigerant into the multiple first flow channels 214; the water-passing pipe group 800 is used to pass water into the multiple spraying assemblies 400. In this embodiment, by arranging multiple groups of the first mold 210 and the second mold 220, the ice maker in the present application can have multiple ice-making cavities 230 during one ice-making process, that is, multiple ice bodies can be made at one time, which can effectively improve the ice-making efficiency of the ice maker. Further, by passing refrigerant into the multiple first flow channels 214 through the first medium-passing pipe group 700, the efficiency of the refrigerant entering the multiple first flow channels 214 can be improved. Similarly, the second medium-passing pipe can pass water into the multiple water inlet flow channels 420 in the multiple groups of spraying assemblies 400. In this way, the efficiency of water entering the multiple water inlet flow channels 420 can be improved. Further, the multiple water return holes 225 in the multiple groups of spraying assemblies 400 can be connected to a single pipeline and returned to the water return box.

[0094] In this embodiment, when the second mold 220 is provided with a second flow channel (not shown), the present application may further be provided with a second medium-passing pipe group (not shown), and the second medium-passing pipe group passes heat medium through the multiple second flow channels.

[0095] In one embodiment, referring to Figure 3 、 Figure 4, when the first mold 210 and the second mold 220 are configured in multiple numbers, specifically, when the first mold 210 includes a first mold body 211 and a first mold cover 212, the first mold covers 212 in multiple groups of the first molds 210 are integrally formed, and the first mold bodies 211 in multiple groups of the first molds 210 are integrally formed; when the second mold 220 includes a second mold body 221 and a second mold cover 222, the second mold covers 222 in multiple groups of the second molds 220 are integrally formed, and the second mold bodies 221 in multiple groups of the second molds 220 are integrally formed; when the second mold 220 includes a third mold body, the third mold bodies in multiple groups of the second molds 220 are integrally formed; at this time, it is convenient to produce and manufacture the first mold 210 and the second mold 220. At the same time, the driving assembly 300 can conveniently drive multiple second molds 220 to move synchronously.
