[0069] The present utility model provides an ice maker.

[0070] Please refer to Figure 1 、 Figure 3 、 Figure 5 , in an embodiment of the present utility model, the ice maker includes:

[0071] A frame 100a;

[0072] A mold assembly 200a, including a first mold 210a and a second mold 220a. The first mold 210a is fixedly arranged on the frame 100a and has at least one first mold cavity 213a. The second mold 220a is movably installed on the frame 100a and has at least one second mold cavity 223a; and

[0073] The driving component 300a is installed on the frame 100a and is drivingly connected to the second mold 220a, and can drive the second mold 220a to flip, so that the second mold 220a has a first position closed relative to the first mold 210a and a second position opened relative to the first mold 210a; when the driving component 300a drives the second mold 220a to flip and the second mold 220a is in the first position, the second mold 220a is combined with the first mold 210a, and the first mold cavity 213a and the second mold cavity 223a form an ice-making cavity 230a, and the ice-making cavity 230a is used for making ice, and one first mold cavity 213a and one second mold cavity 223a are correspondingly arranged; when the number of the first mold cavities 213a and the second mold cavities 223a is set to one, the number of the ice-making cavities 230a is one; when the number of the first mold cavities 213a and the second mold cavities 223a is set to three, the number of the ice-making cavities 230a is also three; when the ice-making is completed, when the driving component 300a drives the second mold 220a to the second position, the ice can be separated from the mold assembly 200a. In this embodiment, before ice-making, the driving component 300a drives the second mold 220a to flip first, so that the second mold 220a flips to the first position, and at this time the second mold 220a is combined with the first mold 210a (see Figure 3 ), the first mold cavity 213a and the second mold cavity 223a form 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 a 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 a preset cooling time, the water in the ice-making cavity 230a is frozen into ice. When the water in the ice-making cavity 230a is completely frozen into ice, the driving component 300a drives the second mold 220a to flip, so that the second mold 210a moves to the second position, and at this time the second mold 220a and the first mold 210a are in an open state (see Figure 8 ). After opening, the ice body can be separated from the mold assembly 200a.

[0074] The technical solution of the present utility model drives the second mold 220a to flip by using the driving assembly 300a; when ice making is required, the driving assembly 300a drives the second mold 220a to flip to the first position. At this time, the second mold 220a is combined 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; after the ice making is completed, the driving assembly 300a drives the second mold 220a to flip, so that the first mold 210a reaches the second position. At this time, the mold assembly 200a is opened, and then the ice can be removed from the first mold cavity 213a or the second mold cavity 223a. In this application, the driving assembly 300a drives the second mold 220a to flip to realize the combination and opening of the mold assembly 200a, which can effectively improve the automation degree of mold opening during the ice-making process of the ice maker, and thus solve the technical problems existing in the prior art.

[0075] In one embodiment, referring to Figure 2 , the second mold 220a and the first mold 210a are hinged through a rotating shaft 10a; wherein, a first through hole 215a for the rotating shaft 10a to pass through is provided in the first mold 210a, and a second through hole 226a for the rotating shaft 10a to pass through is provided in the second mold 220a; further, the second mold 220a includes a cover body 216a, and the first through hole 215a is opened in the cover body 216a, and the cover body 216a is fixedly arranged on the frame 100a.

[0076] In one embodiment, referring to Figure 2 , the driving assembly 300a includes a driving member, and the driving member is drivingly connected to the second mold. Further, the driving member is configured as a driving motor 330a, and the driving motor 330a is drivingly 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 drivingly 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 fixedly arranged, and the rotating shaft 10a is in clearance fit 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.

[0077] In one embodiment, referring to Figure 2, the driving assembly 300a further includes a first spring 350a and a connecting arm 360a. The connecting arm 360a is fixedly arranged, specifically, the connecting arm 360a is fixedly arranged on 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 removal process, the driving assembly 300a drives the second mold 220a to flip to the second position, and the first spring 350a is stretched through the connecting arm 360a. At this time, the first spring 350a is deformed by the tensile force. When the ice removal is completed and the second mold 220a and the first mold 210a need to be combined, the restoring force of the first spring 350a can be used to make the second mold 220a rotate around the rotating shaft 10a to be combined with the first mold 210a. In this way, the driving assembly 300a does not need to drive the second mold 220a to be combined with the first mold 210a, and the second mold 220a can be combined with the first mold 210a under the action of the first spring 350a.

[0078] However, this design is not limited to this. In other embodiments, the second mold 220a can also be hinged to the frame 100a through the rotating shaft 10a.

[0079] However, this design is still 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 slider guide rail structure is fixedly arranged, and it can be fixedly arranged on the first mold 210a or on the frame 100a. One end of the connecting rod in the connecting rod and slider guide rail structure is hinged to the middle position of the second mold 220a, and the other end is hinged to the first mold 210a or the frame 110a. The slider in the connecting rod and slider guide rail structure slides on the guide rail in its structure, and the slider is also hinged to one end of the second mold 220a. The driving part in the driving assembly is drivingly connected to the slider in this structure, and the slider is driven to move along the guide rail in this structure. As the slider approaches or moves away from the hinge point of 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 combined 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 can complete the mold opening.

[0080] In one embodiment, refer to Figure 5, the first mold 210a is provided with a first flow channel 214a for the refrigerant to flow through. The first flow channel 214a includes multiple turns of flow channels 2141a that are sequentially connected in a direction away from the second mold 220a. Specifically, the multiple turns 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 according to the temperature of the refrigerant introduced into the first flow channel 214a. When the temperature of the introduced refrigerant is relatively low, the refrigerant freezes the water in the ice-making cavity 230a. When the temperature of the introduced refrigerant is relatively high, that is, high-temperature refrigerant, the high-temperature refrigerant can thaw the ice body and the cavity wall of the first mold cavity 213a.

[0081] In this embodiment, since the first flow channel 214a includes multiple turns of flow channels 2141a that are sequentially connected in a direction away from the second mold 220a, the relative contact area between the first flow channel 214a and the first mold cavity 213a can be increased under the action of the multiple turns of flow channels 2141a. At this time, after the refrigerant is introduced into the first flow channel 214a, due to the increase in the relative contact area between the first flow channel 214a and the first mold cavity 213a, the energy of the refrigerant can be transferred to the ice-making cavity 230a faster at this time, so that the ice-making cavity 230a can be quickly cooled, and then the water in the ice-making cavity 230a can be quickly frozen. Similarly, when it is necessary to thaw the ice body and the cavity wall of the first mold cavity 213a, the purpose of rapid thawing can also be achieved under the action of the first flow channel 214a.

[0082] In one embodiment, when the first mold 210a is provided with the first flow channel 214a for the refrigerant to flow through, for any one turn of the flow channel 2141a in the middle, the connection points (not shown) between it and the adjacent turn of the flow channel 2141a close to the second mold 220a and the connection points between it and the adjacent turn of the flow channel 2141a away from the second mold 220a are located on opposite sides of this turn of the flow channel 2141a. That is to say, after the refrigerant is introduced into the first flow channel 214a, it first enters the upper-layer flow channel 2141a, then flows along the upper-layer flow channel 2141a to the connection point. At this time, it enters the middle-layer flow channel 2141a through the connection point, and then flows along the middle-layer flow channel 2141a to the connection point. At this time, it flows into the lower-layer flow channel 2141a through the connection 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. In this way, it can be avoided that the refrigerant directly enters the middle-layer and lower-layer flow channels 2141a from the upper-layer flow channel 2141a, the flow path of the refrigerant in the first flow channel 214a can be increased, and then the relative contact area between the refrigerant and the first mold cavity 213a can be increased.

[0083] In one embodiment, the first mold 210a may adopt the following structure. 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 a cover body 216a. The first mold cover 212a is arranged to cover the first mold body 211a. The first mold cavity 213a is formed on the side of the first mold body 211a facing away from the first mold cover 212a. The first runner 214a is formed between the first mold cover 212a and the first mold body 211a. Specifically, by forming the first runner 214a between the first mold cover 212a and the first mold body 211a, it is arranged to surround the first mold body 211a, so as to achieve the purpose of surrounding the first mold cavity 213a. The first runner 214a surrounds the first mold body 211a for one or more circles, and further realizes that the first runner 214a surrounds the first cavity for 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 runner 214a can be formed on the outside of the first mold body 211a. At this time, the first runner 214a is located between the first mold cover 212a and the first mold body 211a. At the same time, when the thickness of the cavity wall of the first mold cavity 213a is the same, the energy in the first runner 214a surrounding the outside of the first mold body 211a can be evenly transmitted to the first mold cavity 213a through the first mold body 211a, so as to make the ice-making cavity 230a more uniform during freezing, or during the thawing process, the thawing is more uniform, and the ice body after thawing is more complete.

[0084] However, this design is not limited thereto. 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. At this time, the first runner 214a is formed on the outside of the first mold body 211a.

[0090] In one embodiment, refer to Figure 7 , the second flow channel 227a includes multiple turns of flow channels that are sequentially connected in the direction away from the first mold 210a, and the multiple turns of flow channels in the second flow channel 227a are similar or the same in structure as the multiple turns of flow channels in the first flow channel 214a.

[0091] In one embodiment, refer to Figure 7 , the second mold 220a includes a second mold body 221a and a second mold cover 222a. The second mold cover 222a is arranged to cover the second mold body 221a. The second mold cavity 223a is formed on the side of the second mold body 221a facing away from the second mold cover 222a. The second flow channel 227a is arranged 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, and a groove structure (not shown) is formed in the second mold cover 222a. When the second mold cover 222a covers the second mold body 221a, the second flow channel 227a can be formed outside the second mold body 221a. At this time, the second flow channel 227a is located between the second mold cover 222a and the second mold body 221a.

[0092] However, the present design is not limited thereto. 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. At this time, the second runner 227a is formed outside the second mold body 221a. Specifically, a pipeline (not shown) is fixedly installed outside the second mold body 221a, and the second runner 227a is arranged in the pipeline, and the pipeline may be arranged around the outside of the second mold body 221a for one or more turns.

[0093] In one embodiment, referring to Figure 6 , the second mold 220a is located below the first mold 210a;

[0094] The ice maker further includes a water storage tray 20a, and the water storage tray 20a is installed on the second mold 220a. The water storage tray 20a is used for storing a thawing medium so that the thawing medium soaks the second mold 220a. In this embodiment, the thawing medium may be a high-temperature refrigerant or high-temperature water. The thawing medium is introduced into the water storage tray 20a. At this time, the thawing medium transfers heat energy to the second mold cavity 223a through the second mold 220a. Under the action of the heat energy, the ice body and the inner wall of the second mold cavity 223a are melted to complete thawing.

[0095] Furthermore, when the ice maker further includes the water storage tray 20a, the mold assembly 200a can adopt one of the following multiple methods during the ice removal process; during the ice removal process, the thawing medium is introduced into the water storage tray 20a to thaw the ice body obtained and the second mold 220a, and then the second mold 220a is driven by the driving assembly 300a to flip to the second position, and then a high-temperature refrigerant is introduced into the first runner to thaw the ice body and the first mold 210a;

[0097] In one embodiment, referring to Figure 4 , Figure 5, the cavity wall of the second mold cavity 223a is provided with equal or nearly equal thickness, and the ice maker further includes a heating element 500a covering the back surface of the cavity wall of the second mold cavity 223a; in one embodiment, when the thickness of the cavity wall of the second mold cavity 223a is the same, the energy in the heating element 500a covering the back surface 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, so as to make the ice-making cavity 230a more uniform during freezing, or during the thawing process, the thawing is more uniform, so that the ice body after thawing is more complete. In this embodiment, when the second mold 220a only includes the second mold body 221a, the back surface of the cavity wall of the second mold cavity 223a is the outer surface of the second mold body 221a; further, when thawing the ice body and the cavity wall of the second mold cavity 223a through the heating element 500a, the heating element 500a can be configured as a heating film, and the heating element 500a generates heat and transfers the heat to the second mold cavity 223a through the second mold body 221a, so as to thaw and melt the ice body and the cavity wall of the second mold cavity 223a.

[0098] Further, when the ice maker further includes a heating element 500a, the mold assembly 200a can adopt one of the following multiple methods during the ice removal process; during the ice removal process, the heating element 500a generates heat to thaw the ice body made and the second mold 220a, and then the driving assembly 300a drives the second mold 220a to flip to the second position, and then high-temperature refrigerant is introduced into the first flow channel to thaw the ice body and the first mold 210a;

[0099] Or during the ice removal process, high-temperature refrigerant is introduced into the first flow channel 214a to thaw the ice body made 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 heating element 500a generates heat to thaw the ice body and the second mold 220a;

[0100] Or during the ice removal process, high-temperature refrigerant is introduced into the first flow channel 214a, and the heating element 500a generates heat to thaw the ice body made and the first mold 210a and the second mold 220a, and then the driving assembly 300a drives the second mold 220a to flip to the second position.

[0101] In one embodiment, refer to Figure 4, the heating element 500a includes a flexible body 510a covering the back of the cavity wall of the second 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 cavity 223a through the flexible body 510a and the second mold body 221a, so as to thaw and melt the ice body and the cavity wall of the second cavity 223a. In this embodiment, the heating element can be a heating wire.

[0102] In one embodiment, the flexible body 510a is configured as a silica gel body, and the silica gel body to be used is one that can withstand high temperatures, at least about 150 °C; however, this design is not limited to this. In other embodiments, the flexible body 510a 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.

[0103] In one embodiment, referring to Figure 4 , the flexible body 510a includes a plurality of flexible flaps 511a arranged in sequence in the circumferential direction of the second mold 220a. The plurality of flexible flaps 511a jointly cover the back of the cavity wall of the second cavity 223a. When the second mold 220a only includes the second mold body 221a, the back of the cavity wall of the second cavity 223a is the outer surface of the second mold body 221a.

[0104] In one embodiment, referring to Figure 8 , Figure 9 , the ice maker further includes an ejector 30a and a driver 60a. The ejector is movably installed on the second mold 220a, and the ejector can movably extend into the second cavity 223a. The driver is drivingly connected to the ejector. In this embodiment, the driver is configured as a ejector rod or an electric telescopic rod (not shown); during the ice removal process, the ejector can eject the ice body from the cavity wall of the second cavity 223a.

[0105] Further, when the ice maker further includes an ejector 30a and a driver 60a, the mold assembly 200a can adopt the following method during the ice removal process; during the ice removal process, high-temperature refrigerant is introduced into the first flow channel 214a to thaw the ice body made and the first mold 210a, and then the second mold 220a is driven to flip to the second position by the driving assembly 300a, and then the ejector is driven by the driver 60a to eject the ice body from the second mold 220a. Further, in this embodiment, referring to Figure 8 , Figures 14 to 16, when the driving member 60a is configured as the ejector rod 61a, the driving member 60a further includes a mounting plate 62a. The mounting plate 62a is fixedly arranged, specifically, the mounting plate 62a is fixedly arranged on the frame, and the ejector rod 61a is fixedly arranged on the mounting plate 62a, wherein the ejector rod 61a is located at the second position; further, the ice maker further includes a guiding member 50a for mounting the ejecting member 30a. The guiding member 50a is fixedly arranged on the second mold 220a. The guiding member 50a includes a guiding tube 51a, a push plate 52a, a first limiting structure 53a, and a second limiting structure 54a. The ejecting member 30a and the push plate 52a are both arranged in the guiding tube 51a, and the ejecting member 30a and the push plate 52a are fixedly connected. A second spring 70a is arranged between the push plate 52a and the first limiting structure 53a. When defrosting, the second driving assembly 300a drives the second mold 220a to flip and approach the second position. When approaching the second position, at this time, 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 ejecting member 30a out of the guiding tube 51a, so that the ejecting member 30a extends into the second mold cavity 223a; when completely located at the second position, the stroke of the ejecting member 30a extending into the second mold cavity 223a is the largest. When the second mold 220a leaves the second position, under the restoring force of the second spring 70a, the push plate is restored to the initial position, thereby driving the ejecting member 30a to contract into the guiding tube 51a. The second limiting structure 54a is used to limit the ejecting member 30a in the guiding tube 51a to prevent the ejecting member 30a from detaching from the guiding tube 51a; specifically, in the present application, the guiding tube 51a is arranged to cover at least a part of the second mold 220a, and the first limiting structure 53a is configured as a part of the structure of the second mold 220a located inside the guiding tube 51a. Under the action of the first limiting structure 53a, the push plate 52a and the ejecting member 30a can be prevented from being ejected out of the guiding tube 51a by the restoring force of the second spring 70a. When the driving member is configured as an electric telescopic rod (not shown), 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 ejecting member 30a, so that the ejecting member 30a detaches the ice body from the second mold 220a; when the second mold 220a moves to the first position, the electric telescopic rod retracts the ejecting member 30a. During the defrosting process, high-temperature refrigerant is introduced into the first flow channel 214a to thaw the ice body made and the first mold 210a, and then the second mold 220a is driven to move to the second position by the driving assembly 300a, and the driving member drives the ejecting member 30a, so that the ejecting member 30a ejects and detaches the ice body from the second mold 220a.

[0106] In one embodiment, referring to Figure 16, the ejecting member 30a can be configured as the mounting base 410a in the spraying assembly 400a. An avoidance hole for the second water inlet flow channel 420a to pass through is formed in the push plate 52a of the guiding member 50a. Meanwhile, a mounting hole 224a for mounting the mounting base 410a is provided in the second mold 220a, and a limiting step 2241a is formed in the mounting hole 224a. The second limiting structure 54a is configured as the limiting step 2241a. During the ice removal process, the ejector rod 61a pushes against the push plate 52a, the push plate 52a compresses the spring 70a, and the mounting base 410a is ejected from the mounting hole 224a, so that the mounting base 410a extends into the second mold cavity 223a to eject the ice body from the second mold cavity 223a. After the ice removal 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 base 410a return to their original positions. At this time, the mounting base 410a enters the mounting hole 224a, and under the action of the limiting step 2241a, the mounting base 410a is restricted in the mounting hole 224a.

[0107] In one embodiment, the first mold 210a and the second mold 220a are made of a material with good thermal conductivity, and aluminum material can be preferably used. Under the action of the material with good thermal conductivity, it is convenient for the energy of the refrigerant, or the high-temperature refrigerant, or the heating element 500a, or the thawing medium to be conducted to the mold cavity.

[0108] In one embodiment, referring to Figure 5 , Figure 10 , Figure 12 , the ice maker further includes a spraying assembly 400a. The spraying assembly 400a includes a mounting base 410a provided with a water inlet flow channel 420a and spraying holes 430a, and a guiding member 440a installed in the spraying holes 430a. The mounting base 410a is installed on the second mold 220a. The water inlet flow channel 420a is used for water input, and the guiding member 440a is used to make the water sprayed out through the spraying holes 430a in a dispersed state. In this embodiment, the guiding member 440a is configured as a spiral nozzle 441a or a spiral guiding vane 442a. The second mold 220a is provided with a mounting hole 224a for mounting the mounting base 410a, and the mounting base 410a is fixedly arranged in the mounting hole 224a. When the spraying assembly 400a sprays water towards the ice making cavity 230a, the water enters through the water inlet flow channel 420a and then is sprayed towards the ice making cavity 230a through the spraying holes 430a. Since the guiding member 440a is arranged in the water inlet flow channel 420a, the water sprayed out through the spraying holes 430a is in a dispersed state. In this way, multi-angle water spraying can be realized, which is convenient for relatively uniform spraying inside the ice making cavity 230a, so that ice layers are relatively uniformly formed on the ice making cavity 230a.

[0109] In this embodiment, referring to Figure 12 , Figure 13, when the flow guide member 440a is configured as the spiral nozzle 441a, the water ejected toward the ice-making chamber 230a through the spray holes 430a can be in a dispersed state.

[0110] In this embodiment, referring to Figure 10 , Figure 11 , when the spiralized flow guide vane 442a is installed in the spray hole 430a, that is to say, when the flow guide member 440a is configured as the spiralized flow guide vane 442a, a fluid spiralization generation chamber 460a is formed between the spiralized flow guide vane 442a and the spray hole 430a. A conical structure 450a is formed between the fluid spiralization generation chamber 460a and the spray hole 430a. The spiralized flow guide vane 442a includes a dividing portion 4421a and two flow guide portions 4422a. Both of the two flow guide portions 4422a are installed on the dividing portion 4421a. The flow guide portions 4422a are spiral-shaped. The dividing portion 4421a is used to divide the water in the water inlet channel 420a into two parts. The two parts of water respectively move spirally along the two flow guide portions 4422a and enter the fluid spiralization generation chamber 460a to generate spiral flow. Under the action of the conical structure 450a, the spirally moving water can flow better to the spray hole 430a. At this time, the water ejected from the spray hole 430a can be in a dispersed state, and thus multi-angle water spraying can be realized, which is convenient for uniformly spraying the ice-making chamber 230a, so that an ice layer can be uniformly formed on the ice-making chamber 230a.

[0111] In one embodiment, referring to Figure 3 , the first mold 210a is further provided with an exhaust hole 260a. Further, the second mold 220a is arranged below the first mold 210a. During the ice-making process, when the spraying assembly 400a sprays water onto the cavity wall of the ice-making chamber 230a, 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 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.

[0112] In one embodiment, the second mold 220a is further provided with a water return hole 225a. Further, the second mold 220a is arranged below the first mold 210a, and the water return hole 225a can be opened in the second mold 220a. The unaggregated water in the ice-making chamber 230a can be collected through the water return hole 225a, avoiding the situation that the unaggregated water accumulates in the second mold cavity 223a for a long time and causes it to condense, resulting in blockage of the spray hole 430a.

[0113] In one embodiment, referring to Figures 10 to 12, the water return hole 225a can be arranged in the mounting seat 410a mounted on the second mold 220a. Specifically, the water return hole 225a is opened in the mounting seat 410a, one end of which communicates with the second mold cavity 223a, and the other end communicates with the outside of the second mold 220a. In this embodiment, when the second mold 220a is arranged below the first mold 210a, at this time, when the spraying assembly 400a mounted in the second mold 220a sprays water into the ice-making cavity 230a, the sprayed water is upward. After spraying, part of the water that has not condensed in the ice-making cavity 230a will flow downward under the action of gravity, and at this time, it can flow into the water return hole 225a. Further, for the convenience of using the water return hole 225a, the water return hole 225a is arranged at a lower position in the second mold cavity 223a. In this way, it is convenient for the water return hole 225a to collect the uncondensed water. Further, the water return hole 225a is integrated on the mounting seat 410a of the spraying assembly 400a, which can simplify the installation process of this application. After the spraying assembly 400a is mounted on the second mold 220a, its water return hole 225a is also mounted. In this application, the water return hole 225a communicates with the water return box, and the water flowing into the water return hole 225a flows into the water return box.

[0114] In one embodiment, referring to Figure 9 , the above-mentioned 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 drivingly connected to the mounting seat 410a, and the driving member drives the mounting seat 410a to eject the ice body from the second mold cavity 223a.

[0115] In one embodiment, the ice maker further includes an ice guiding structure 600a. The ice guiding structure 600a includes an ice guiding plate. The ice guiding plate is arranged below the mold assembly 200a, and the ice guiding plate is used to guide the ice body out of the ice maker.

[0116] In this embodiment, the ice guiding plate can be a whole plate or composed of two parts. When the ice guiding plate is composed of two parts, referring to Figure 1 、 Figure 2, the ice guide plate includes a first ice guide plate 610a and a second ice guide plate 620a. At this time, the ice guiding structure 600a further includes a driving structure 630a, where the driving structure 630a includes a first swing arm 631a and a second swing arm 632a. Both the first swing arm 631a and the second swing arm 632a are 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. Moreover, torsion springs 633a are 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 springs 633a, the first ice guide plate 610a and the second ice guide plate 620a can be located outside the mold assembly 200a; further, the driving structure 630a further includes a driving plate 634a, a transmission member 635a, and a linear driving structure 636a. The linear driving structure 636a drives the driving plate 634a to move linearly. Further, the first swing arm 631a is disposed below the second swing arm 632a. When the linear driving structure 636a drives the driving plate 634a to move downward, at this time, the driving plate 634a can press down the first swing arm 631a to make the first swing arm 631a 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 2 ). Further, 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. The transmission gear 6351a and the third swing arm 6353a are both installed on the frame 100a. The third swing arm 6353a and the transmission gear 6351a are engaged, that is to say, a driven gear 6354a is provided on the third swing arm 6353a to cooperate with the transmission gear 6351a. Specifically, when the transmission gear 6351a rotates, under the action of the driven gear 6354a, the third swing arm 6353a can swing. The third swing arm 6353a is drivingly 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, and the swing of the second swing arm 632a further 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 driving structure 636a drives the driving plate 634a to move downward (see Figure 2), the driving teeth 6352a on the driving plate 634a can be engaged with the transmission gear 6351a. As the driving plate 634a continues to move towards the second position, the transmission gear 6351a is rotated accordingly. When the transmission gear 6351a rotates, the third swing arm 6353a is driven 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 guide plate 620a, so that the second ice guide plate 620a is located between the first mold 210a and the second mold 220a. When the linear driving structure 636a drives the driving plate 634a to move upward (see Figure 1 ), at this time, the driving teeth 6352a drive the transmission gear 6351a to rotate, so that the third swing arm 6353a returns 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, and thus is located outside the mold assembly 200a. At the same time, the driving 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, and thus is located outside the mold assembly 200a.

[0117] In one embodiment, referring to Figure 4 , the first mold 210a, the second mold 220a, the spraying assembly 400a, the first flow channel 214a and the second flow channel 227a, or the heating element 500a, or the ejector 30a are all configured in multiple groups and are arranged in one-to-one correspondence; the ice maker further includes a first medium pipe group 700a and a water pipe group 800a. The first medium pipe group 700a is used to introduce refrigerant into the multiple first flow channels 214a; the water pipe group 800a is used to introduce water into the multiple spraying assemblies 400a. In this embodiment, by providing multiple groups of the first mold 210a and the second mold 220a, the ice maker of the present application can have multiple ice-making cavities 230a 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 introducing refrigerant into the multiple first flow channels 214a through the first medium pipe group 700a, the efficiency of the refrigerant entering the multiple first flow channels 214a can be improved. Similarly, the water pipe group 800a introduces water into the multiple water inlet flow channels 420a of the multiple spraying assemblies 400a. In this way, the efficiency of water entering the multiple water inlet flow channels 420a can be improved. Further, the multiple water return holes 225a in the multiple spraying assemblies 400a can be connected to a single pipeline and return to the water return box.

[0118] In this embodiment, when the second mold 220a is provided with a second flow channel 227a, the present application can also be provided with a second medium pipe group (not shown), and the second medium pipe group passes the heat medium through the multiple second flow channels 227a.
