[0067] The present utility model provides an ice maker.

[0068] Please refer to Figure 3 、 Figure 4 In an embodiment of the present utility model, the ice maker includes:

[0069] A frame 100b;

[0070] A mold assembly 200b, including a first mold 210b and a second mold 220b. The first mold 210b is fixedly arranged on the frame 100b and has at least one first mold cavity 213b. The second mold 220b is movably installed on the frame 100b and has at least one second mold cavity 223b; and

[0071] A driving assembly 300b, installed on the frame 100b and drivingly connected to the second mold 220b, capable of driving the second mold 220b to move horizontally, so that the second mold 220b has a first position where it closes relative to the first mold 210b and a second position where it opens relative to the first mold 210b. Specifically, in this embodiment, the driving assembly 300b drives the second mold 220b to move horizontally, including horizontal movement and horizontal movement at a certain inclination angle, excluding vertical movement; when the driving assembly 300b drives the second mold 220b to the first position, the second mold 220b is combined with the first mold 210b, and the first mold cavity 213b and the second mold cavity 223b form an ice-making cavity 230b for making ice; wherein, one first mold cavity 213b and one second mold cavity 223b are correspondingly arranged; when the number of the first mold cavity 213b and the second mold cavity 223b is set to one, the number of the 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 the ice-making cavities 230b is also three; when the ice-making is completed, when the driving assembly 300b drives the second mold 220b to the second position, the ice can be separated from the mold assembly 200b. Further, 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 is a spherical structure is given. However, the design is not limited to the embodiment of the spherical structure. In other embodiments, the ice-making cavity 230b can also be an ellipsoid, a cylinder, a cube structure, etc., which are convenient for demolding.

[0072] The technical solution of the present utility model drives the second mold 220b to move linearly by adopting a driving assembly 300b, wherein the driving assembly 300b is configured as a linear driving assembly 300b; when ice making is required, the driving assembly 300b drives the second mold 220b to move horizontally until it reaches the first position. At this time, the second mold 220b is combined 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 assembly 200b, the temperature of the water in the ice-making cavity 230b is reduced, and the water is frozen into ice; after ice making is completed, the driving assembly 300b drives the second mold 220b to move until the second mold 220b reaches the second position. At this time, the mold assembly 200b is opened, and then the ice can be removed from the first mold cavity 213b or the second mold cavity 223b. In this application, by driving the second mold 220b to move through the driving assembly 300b, the combination and opening of the mold assembly 200b are realized, 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.

[0073] In one embodiment, referring to Figure 4 、 Figure 5 , the ice maker further includes a spraying assembly 400b. The spraying assembly 400b includes a mounting seat 410b provided with a first water inlet flow channel 420b and spraying holes 430b, and a guiding member 440b installed in the first water inlet flow channel 420b. The mounting seat 410b is installed on the second mold 220b. The first water inlet flow channel 420b is used for water input, and the guiding member 440b is used to make the water sprayed out through the spraying holes 430b in a dispersed state; in this embodiment, the second mold 220b is provided with a mounting hole 224b for mounting the mounting seat 410b, and the mounting seat 410b is fixed in the mounting hole 224b. When the spraying assembly 400b sprays water towards the ice-making cavity 230b, the water enters through the first water inlet flow channel 420b and then is sprayed towards the ice-making cavity 230b through the spraying holes 430b. Since the guiding member 440b is arranged in the first water inlet flow channel 420b, the water sprayed out through the spraying holes 430b 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 230b, so that an ice layer is relatively uniformly condensed on the ice-making cavity 230b. In this embodiment, during the ice-making process, the first mold cavity and the second mold cavity form an ice-making cavity, and water is injected into the ice-making cavity through the first water inlet flow channel.

[0074] In this embodiment, referring to Figure 8, the deflector 440b is configured as a spiral nozzle 441b or a spiralized deflector vane 442b; when the deflector 440b is configured as the spiral nozzle 441b, the water sprayed toward the ice-making chamber 230b through the spray holes 430b can be in a dispersed state.

[0075] In this embodiment, referring to Figure 5 , Figure 7 , when the deflector 440b is configured as the spiralized deflector vane 442b, a fluid spiralization generation chamber 460b is formed between the spiralized deflector vane 442b and the spray holes 430b, a conical structure 450b is formed between the fluid spiralization generation chamber 460b and the spray holes 430b, the spiralized deflector vane 442b includes a dividing portion 4421b and two deflector portions 4422b, both of the two deflector portions 4422b are installed on the dividing portion 4421b, the deflector portions 4422b are spiral-shaped, the dividing portion 4421b is used to divide the water in the first water inlet flow channel 420b into two parts, the two parts of water respectively move spirally along the two deflector portions 4422b and enter the fluid spiralization generation chamber 460b to generate spiral flow, under the action of the conical structure 450b, the spirally moving water can flow better to the spray holes 430b, and at this time, the water sprayed from the spray holes 430b can be in a dispersed state, so that multi-angle water spraying can be realized, which is convenient for relatively uniform spraying in the ice-making chamber 230b, and makes the ice layer condense relatively uniformly on the ice-making chamber 230b.

[0076] In one embodiment, referring to Figure 3 , the ice maker further includes a water injection pipe 40b. After the first mold 210b and the second mold 220b are closed, a second water inlet flow channel 240b is formed above between the first mold 210b and the second mold 220b, and the water injection pipe 40b is used to inject water into the closed first mold 210b and second mold 220b through the second water inlet flow 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 a refrigerant to freeze it into an ice body.

[0077] In one embodiment, the second water inlet flow channel 240b includes a connected confluence section 241b and a plurality of diversion sections 242b (see Figure 15) The flow splitting section 242b is in communication with the mold cavity, that is, the flow splitting section 242b is in communication with the ice making cavity 230b. The confluence section 241b has a gradually expanding trend from the connection with the flow splitting section 242b towards the water inlet of the second water inlet channel 240b. In this way, the area of the water inlet of the second water inlet channel 240b can be made larger, which is convenient for water to enter the second water inlet channel 240b when the water injection pipe 40b injects water into the second water inlet channel 240b, and then enters the ice making cavity 230b through a plurality of flow splitting channels 2141b. At the same time, by arranging a plurality of flow splitting sections 242b, the water in the confluence section 241b can enter the ice making cavity 230b faster.

[0078] During the ice making process, the water injection pipe 40b can be used together with the spraying assembly 400b, so that the ice maker of the present application has two water injection structures during the ice making process. When the two water injection structures work simultaneously, the water injection time can be effectively shortened, the water injection efficiency can be improved, and further the ice making efficiency can be improved. Further, when the water injection pipe 40b and the spraying assembly 400b are used together, the water injection pipe 40b can inject water first and then the spraying assembly 400b injects water, or the spraying assembly 400b injects water first and then the water injection pipe 40b injects water, or the spraying assembly 400b and the water injection pipe 40b inject water simultaneously. Or, only the water injection pipe 40b injects water into the ice making cavity 430b. Or, only the spraying assembly 400b injects water into the ice making cavity 430b.

[0079] In one embodiment, referring to Figure 4 、 Figure 10 , the first mold 210b is provided with a first flow channel 214b for the refrigerant to flow through; in this embodiment, according to the temperature of the refrigerant flowing into the first flow channel 214b, the first mold 210b can have different effects. When the temperature of the refrigerant flowing in is relatively low, the refrigerant freezes the water in the ice making cavity 230b. When the temperature of the refrigerant flowing in is relatively high, the refrigerant can thaw the ice block and the cavity wall of the first mold cavity 213b.

[0080] In one embodiment, referring to Figure 4 、 Figure 10 , the first flow channel 214b includes multiple turns of flow channels 2141b that are sequentially connected in a direction away from the second mold 220b. Specifically, the multiple turns 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 multiple turns of flow channels 2141b, the relative contact area between the first flow channel 214b and the first mold cavity 213b can be increased. After the refrigerant is introduced into the first flow channel 214b at this time, 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 faster at this time, so that the ice making cavity 230b is quickly cooled, and further the purpose of quickly freezing the water in the ice making cavity 230b is achieved.

[0081] In one embodiment, referring to Figure 4 、 Figure 10 , for any one of the middle circular flow channels 2141b, the connection points of it with the adjacent circular flow channels 2141b close to the second mold 220b and the connection points of it with the adjacent circular flow channels 2141b far from the second mold 220b are disposed on opposite sides of this circular flow channel 2141b. That is to say, after the refrigerant enters the first flow channel 214b, it first enters the upper-layer flow channel 2141b, then flows along the upper-layer flow channel 2141b to the connection point. At this time, it enters the middle-layer flow channel 2141b through the connection point, and then flows along the middle-layer flow channel 2141b to the connection point. At this time, it flows into the lower-layer flow channel 2141b through the connection point between 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. In this way, it can be avoided that the refrigerant directly enters the middle-layer and lower-layer flow channels 2141b from the upper-layer flow channel 2141b, the flow path of the refrigerant in the first flow channel 214b can be increased, and thus the relative contact area between the refrigerant and the first mold cavity 213b can be increased.

[0082] In one embodiment, referring to Figure 4 、 Figure 10 , the first mold 210b can adopt the following structure. The first mold 210b includes a first mold body 211b and a first mold cover 212b. The first mold cover 212b is disposed to cover the first mold body 211b. The first mold cavity 213b is formed on the side of the first mold body 211b facing away from the first mold cover 212b. The first flow channel 214b is formed between the first mold cover 212b and the first mold body 211b. Specifically, by forming the first flow channel 214b between the first mold cover 212b and the first mold body 211b, it is arranged to surround the first mold body 211b, so as to achieve the purpose of surrounding the first mold cavity 213b. The first flow channel 214b surrounds the first mold body 211b for one or more circles, and further realizes that the first flow channel 214b surrounds the first cavity for 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 can be formed outside the first mold body 211b. At this time, 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 thickness of the cavity wall of the first mold cavity 213b is the same, the energy in the first flow channel 214b surrounding the outside of the first mold body 211b can be evenly transmitted to the first mold cavity 213b through the first mold body 211b, so as to realize more uniform freezing of the ice-making cavity 230b, or more uniform thawing during the thawing process, and make the thawed ice body more complete.

[0083] However, the present design is not limited thereto. 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. At this time, the first runner 214b is formed on the outside of the first mold body 211b. Specifically, a pipeline (not shown) is fixedly provided outside the first mold body 211b, and the first runner 214b is arranged in the pipeline, and the pipeline can be arranged around the outside of the first mold body 211b for one or more turns.

[0084] In this application, Figure 4 、 Figure 9 The ice makers in all adopt the above-mentioned first mold 210b, wherein the first runner 214b includes multiple turns of runners 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 differences are only in the number of the first mold body 211b, the first mold cavity 213b, the first runner 214b, and the length of the first mold cover.

[0085] In one embodiment, referring to Figure 12 、 Figure 13 , the first mold 210b is embedded with a copper tube 217b for the refrigerant to flow through. The first mold cavity 213b is formed on the side of the first mold 210b facing away from the copper tube 217b. By introducing refrigerants at different temperatures into the copper tube 217b, the copper tube 217 transfers the energy of the refrigerant to the first mold 210b, and then to the first mold cavity 213b, so as to freeze the water in the ice making cavity 230b, or thaw the ice body and the cavity wall of the first mold cavity 213b.

[0086] In one embodiment, the first mold 210b includes a first mold cover 212b and two first mold bodies 211b (the embodiment with only two first mold bodies 211b is not shown). The two first mold bodies 211b are respectively arranged on opposite sides of the first mold cover 212b. The first mold cover 212b covers at least part of the two first mold bodies 211b. The first mold cavity 213b is formed on the side of the first mold body 211b facing away from the first mold cover 212b. The first mold cover 212b and the two first mold bodies 211b enclose to form the first runner 214b (see Figure 15 、 Figure 17); In this way, the first mold cavities 213b in the two first mold bodies 211b can share a first runner 214b. That is to say, when the refrigerant is injected into the first runner 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 runner 214b, the refrigerant in the first runner 214b can cool the first mold cavities 213b in the two first mold bodies 211b, and cool the two ice-making cavities 230b formed by the two first mold bodies 211b and the two first molds 210b, so that the water injected and / or sprayed into the ice-making cavity 230b condenses into ice. In this way, the ice-making machine of the present application can make multiple ice cubes at one time, and sharing a first runner 214b by the two ice-making cavities 230b can reduce the production cost of the ice-making machine.

[0087] In one embodiment, referring to Figure 14 , Figure 16 , Figure 18 , the first runner 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 runner 214b includes multiple sections of runners 2141b arranged between the two first mold bodies 211b. The multiple sections of runners 2141b are arranged in sequence along the second direction, and the second direction is perpendicular to the first direction. For any middle section of the runner 2141b, its two communication parts with the adjacent two sections of runners 2141b are respectively arranged at the opposite ends of this section of the runner 2141b along the first direction (see Figure 20 ); The second molds 220b are arranged in one-to-one correspondence with the first mold bodies 211b. The two second molds 220b are respectively arranged on the opposite sides of the first mold 210b. Specifically, when the refrigerant enters the first runner 214b, it first enters an outer runner 2141b, then flows along this runner 2141b to the communication part between the outer runner 2141b and the middle runner 2141b, and enters the middle runner 2141b through this communication part. At this time, it continues to flow along the middle runner 2141b to the communication part between the middle runner 2141b and the other outer runner 2141b, and enters the outer runner 2141b through this communication part. Since for any middle section of the runner 2141b, its two communication parts with the adjacent two sections of runners 2141b are respectively arranged at the opposite ends of this section of the runner 2141b along the first direction, in this way, in this embodiment, the refrigerant in the first runner 214b can flow in a meandering manner (see Figure 20 ). Under the action of this flow mode, the contact area between the first runner 214b and the two first mold bodies 211b can be increased, so as to increase the relative contact area between the first mold cavity 213b and the refrigerant, which is convenient for improving the energy transmission effect.

[0088] In one embodiment, when there are multiple first mold bodies 211b provided on the same side of the first mold cover 212b, there are also multiple second molds 220b provided on the same side of the first mold cover 212b (see Figures 14 to 19 ), that is to say, there are multiple ice-making cavities 230b provided on the same side of the first mold cover 212b; at the same time, when there are multiple ice-making cavities 230b provided on the first mold cover 212b, the above-mentioned water injection pipe 40b injects water into multiple second water inlet channels 240b. At this time, the water injection pipe 40b has a flow-dividing function. Multiple first channels 214b corresponding to the multiple first mold bodies 211b one by one are provided in the first mold cover 212b, and adjacent two of the first channels 214b are separated by a partition 270b (see Figure 20 ). In this way, it is convenient to install the first mold 210b, and at the same time, the cost of the first mold 210b can be reduced. However, this design is not limited to this. In other embodiments, only one first channel 214b may be formed by enclosing the first mold cover 212b and the two first mold bodies 211b.

[0089] In one embodiment, one of the first channels 214b is correspondingly arranged with the first mold bodies 211b that are symmetrically arranged on the opposite sides of the first mold cover 212b (see Figure 19 、 Figure 20 ), specifically, one first channel 214b is arranged corresponding to two first mold bodies 211b. However, this design is not limited to this. In other embodiments, one first channel 214b may be arranged corresponding to four or more first mold bodies 211b, that is, the first mold cover 212b and the multiple first mold bodies 211b enclose to form one first channel 214b.

[0090] 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, and the structures or sizes of the ice-making cavities provided on the two sides of the first mold cover are different. When the structures of the ice-making cavities provided on the two sides of the first mold cover are different, on one side of the ice-making cavities on the two sides of the first mold cover, one side may be an ice-making cavity with a quadrangular prism structure, and the ice body formed is a quadrangular prism structure, and the other side may be an ice-making cavity with a spherical structure, and the ice body formed is a spherical structure. When the sizes of the ice-making cavities provided on the two sides of the first mold cover are different, on one side, there may be a spherical ice-making cavity with a larger structure, and the spherical ice body formed has a larger structure, and on the other side, there may be a spherical structure ice-making cavity with a smaller structure, and the spherical ice body formed has a smaller structure.

[0091] In this application, Figures 14 to 20The ice makers therein all adopt the above-mentioned first mold 210b, wherein the first mold cover 212b and the two first mold bodies 211b enclose to form the first flow channel 214b. The structures of the first molds used are similar, and the differences are only in the number of the first mold bodies 211b, the first mold cavities 213b, the first flow channels 214b, and the length of the first mold cover. At the same time, in this application, when the second molds 220b are arranged on both sides of the first mold cover 212b, the corresponding driving components 300b can also be arranged in two groups (see Figure 15 , Figure 17 , Figure 19 ). When the driving components 300b are arranged in two groups, during mold opening, according to the structure and size of the ice bodies obtained, it can be selected that the ice-making cavities on both sides of the first mold cover are opened simultaneously, or it can be selected to open in sequence.

[0092] In an embodiment, the second mold 220b is provided with a second flow channel (not shown) for the thawing medium to flow through. During the ice removal process, the thawing medium is introduced into the second flow channel to thaw the ice bodies obtained and the second mold 220b, and then the second mold 220b is driven by the driving component 300b to move to the second position. Then, high-temperature refrigerant is introduced into the first flow channel to thaw the ice bodies and the first mold 210b. It is also possible to introduce high-temperature refrigerant into the first flow channel 214b during the ice removal process to thaw the ice bodies obtained and the first mold 210b, and then drive the second mold 220b to move to the second position by the driving component 300b, and then introduce the thawing medium into the second channel to thaw the ice bodies and the second mold 220b. It is also possible to introduce high-temperature refrigerant into the first flow channel 214b and introduce the thawing medium into the second channel during the ice removal process to thaw the ice bodies obtained and the first mold 210b and the second mold 220b, and then drive the second mold 220b to move to the second position by the driving component 300b.

[0093] In this embodiment, the second flow channel includes multiple circles of flow channels (not shown) that are sequentially connected in the direction away from the first mold 210b. The multiple circles of flow channels in the second flow channel are similar or the same in structure as the multiple circles of flow channels 2141b in the first flow channel 214b.

[0094] 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 disposed to cover the second mold body 221b. The second mold cavity 223b is formed on a side of the second mold body 221b facing away from the second mold cover 222b. The second runner is disposed 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 a groove structure (not shown) is formed in the second mold cover 222b. When the second mold cover 222b covers the second mold body 221b, the second runner can be formed outside the second mold body 221b. At this time, the second runner is located between the second mold cover 222b and the second mold body 221b.

[0095] However, this design is not limited thereto. In other embodiments, the second mold 220b can also adopt other structures. For example, the second mold 220b can only include the second mold body 221b. At this time, the second runner is formed outside the second mold body 221b. Specifically, a pipeline (not shown) is fixedly provided outside the second mold body 221b, and the second runner is arranged in the pipeline, and the pipeline can be arranged around the outside of the second mold body 221b for one or more turns.

[0096] In one embodiment, refer to Figure 4 、 Figure 5 、 Figure 6, the cavity wall of the second mold cavity 223b is provided with equal or nearly equal thickness. The ice maker further includes a heating element 500b covering the back surface of the cavity wall of the second mold cavity 223b. When the thickness of the cavity wall of the second mold cavity 223b is the same, the energy in the heating element 500b covering the back surface 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, so as to make the ice-making cavity 230b more uniform during freezing, or during the thawing process, the thawing is more uniform, making the ice body after thawing more complete. In this embodiment, when the second mold 220b only includes the second mold body 221b, the back surface of the cavity wall of the second mold cavity 223b is the outer surface of the second mold body 221b; further, when thawing the ice body and the cavity wall of the second mold cavity 223b through the heating element 500b, the heating element 500b can be configured as a heating film. By heating the heating element 500b, the heat is transferred to the second mold cavity 223b through the second mold body 221b, so as to thaw the ice body and the cavity wall of the second mold cavity 223b. During the ice removal process, the heating element 500b generates heat to thaw the produced ice body and the second mold 220b, and then the driving assembly 300b drives the second mold 220b to move 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 210b. It is also possible to introduce high-temperature refrigerant into the first flow channel 214b during the ice removal process 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. It is also possible to introduce high-temperature refrigerant into the first flow channel 214b during the ice removal process and generate heat through the heating element 500b 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.

[0097] In one embodiment, refer to Figure 10 、 Figure 11, the ice maker further includes an ejector 30b and a driver 60b. The ejector 30b is movably installed in the second mold 220b, and the ejector 30b can movably extend into the second cavity 223b. The driver cooperates with the ejector 30b to movably extend the ejector 30b into the second cavity 223b. In this embodiment, the driver is configured as a push rod 61b or an electric telescopic rod (not shown); when the driver is configured as a 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 further includes a guide member 50b for installing 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. A second spring 70b is arranged between the push plate 52b and the first limiting structure 53b. When defrosting, the second driving assembly 300b drives the second mold 220b to move close to the second position. When approaching the second position, at this time, the push 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 out of the guide tube 51b, so that the ejector 30b extends into the second cavity 223b; when completely located at the second position, the stroke of the ejector 30b extending into the second cavity 223b is the largest. When the second mold 220b leaves the second position, under the restoring force of the second spring 70b, the push plate is restored to the initial position, thereby driving the ejector 30b to contract into the guide tube 51b. 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 a part of the second mold 220b. The first limiting structure 53b is configured as a part of the 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 out of the guide tube 51b by the restoring force of the second spring 70b. When the driver is configured as an electric telescopic rod (not shown), 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 detaches 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 defrosting process, high-temperature refrigerant is introduced into the first flow channel 214b to thaw the ice body made and the first mold 210b. Then, the second mold 220b is driven to move to the second position by the driving assembly 300b, and the driver drives the ejector 30b so that the ejector 30b ejects the ice body from the second mold 220b and detaches it.

[0098] In one embodiment, referring to Figure 10 and Figure 11 , the ejector member 30b can be configured as the mounting seat 410b in the spraying assembly 400b. An avoidance hole for the first water inlet channel 420b to pass through is formed in the push plate 52b of the guiding member 50b. Meanwhile, a mounting hole 224b for mounting the mounting seat 410b is provided in the second mold 220b, and a limiting step 2241b is provided in the mounting hole 224b. The second limiting structure 54b is configured as the limiting step 2241b. During the ice removal process, the ejector rod 61b pushes against the push plate 52b. 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 to eject the ice body from the second mold cavity 223b. After the ice removal is completed, the second mold 220b leaves the second position. Under 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.

[0099] In one embodiment, after the first mold 210b and the second mold 220b are closed, a return water hole 250b is formed between the first mold 210b and the second mold 220b at the lower side. Under the action of the return water hole 250b, during the ice making process, part of the water that has not condensed in the ice making cavity 230b will flow downward under the action of gravity and can flow into the return water hole 250b at this time. Further, in order to facilitate the use of the return water hole 250b, the return water hole 250b is arranged at a relatively low position in the mold assembly 200b. In the present application, in order to collect the water in the return water hole 250b, a collection box (not shown) can be arranged below the return water hole 250b.

[0100] In one embodiment, the mold assembly 200b is further provided with an exhaust hole 260b (see Figure 5 and Figure 7 and Figure 13 ). In this embodiment, the exhaust hole 260b can be arranged on the first mold 210b or the second mold 220b. During the ice making process, when the spraying assembly 400b sprays water onto the cavity wall of the ice making cavity 230b and / or when the water injection pipe 40b injects water into the ice making cavity 230b, 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 230b. During the condensation process, the air between the water flow and the cavity wall of the ice making cavity 230b can be discharged through the exhaust hole 260b. Thus, it is convenient to discharge the air in the ice making cavity 230b, thereby improving the quality of the ice body after being made. Further, in this embodiment, the exhaust hole 260b can also be arranged on the mounting seat 410b in the spraying assembly 400b.

[0101] In one embodiment, with reference to Figure 4 , the driving assembly 300b includes a worm 310b, a worm sleeve 310b, a driving motor 330b, and a guide rod 340b. The worm 310b is installed on the frame 100b. The worm sleeve 310b is movably installed on the worm 310b and is fixedly provided with the second mold 220b. The driving motor 330b is drivingly connected to the worm 310b. The second mold 220b is slidably engaged with the guide rod 340b, and the guide rod 340b is fixedly provided on the frame 100b. Specifically, by driving the worm 310b to rotate through the driving motor 330b, at this time, the worm sleeve 310b 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 linearly. When the second mold 220b moves linearly, it can slide along the guide rod 340b, thereby achieving the purpose of driving the second mold 220b to move linearly by the driving structure 630b. The driving assembly 300b further includes a synchronous belt 370b and a plurality of synchronous pulleys 380b (see Figure 17 ). The plurality of synchronous pulleys 380b are installed at the output ends of the worm 310b and the driving motor 330b. Further, the output end of the driving motor 330b is connected to the synchronous pulley 38b0 through a differential. The synchronous belt 370b connects the plurality of synchronous pulleys 380b. When the driving motor 330b rotates, the worm 310b can be driven to rotate through the synchronous pulleys 380b and the synchronous belt 370b. Further, in this embodiment (see Figure 17 ), the worm 310b and the worm sleeve 310b are both configured in two groups. The two groups of worms 310b are respectively arranged on both sides of the second mold 220b, and both groups of worm sleeves 310b are fixedly provided with the second mold 220b. The driving motor 330b is drivingly connected to the two groups of worms 310b through the synchronous belt 370b and the synchronous pulleys 380b. Specifically, synchronous pulleys 380b are provided on the output ends of the two groups of worms 310b and the driving motor 330b. The synchronous belt 370b connects the three synchronous pulleys 380b. At this time, when the output end of the driving motor 330b rotates, the two groups of worms 310b can be driven to rotate simultaneously through the synchronous pulleys 380b and the synchronous belt 370b, thereby realizing the linear movement of the second mold 220b.

[0102] In one embodiment, when the ice maker includes two groups of driving assemblies 300b, the two groups of driving assemblies are symmetrically arranged (see Figure 13 , Figure 15 , Figure 17 ).

[0103] In one embodiment, the ice maker further includes an ice guiding structure 600b, with reference to Figure 1 , Figure 2, the ice guiding structure 600b includes an ice guiding plate disposed below the mold assembly 200b for guiding ice out of the ice maker.

[0104] In this embodiment, the ice guiding plate can be a single piece or composed of two parts.

[0105] Reference Figure 1 , Figure 2 , when the ice guiding plate is composed of two parts, the ice guiding plate includes a first ice guiding plate 610b and a second ice guiding plate 620b. At this time, the ice guiding structure 600b further includes a driving structure 630b. The driving structure 630b includes a first swing arm 631b and a second swing arm 632b. Both the first swing arm 631b and the second swing arm 632b are rotatably connected to the frame 100b. The first ice guiding plate 610b is fixed to the first swing arm 631b, and the second ice guiding plate 620b is fixed to the second swing arm 632b. A torsion spring 633b is provided between both the first ice guiding plate 610b and the second ice guiding plate 620b and the frame 100b. Under the action of the torsion spring 633b, the first ice guiding plate 610b and the second ice guiding plate 620b can be located outside the mold assembly 200b. Further, the driving structure 630b further includes a driving plate 634b, a transmission member 635b, and a linear driving structure 630b. The linear driving structure 630b drives the driving plate 634b to move linearly. Further, the first swing arm 631b is disposed 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 at this time, causing the first swing arm 631b to swing, thereby driving the first ice guiding plate 610b to flip so that the first ice guiding plate 610b is located below the mold assembly 200b. Further, 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. The transmission gear 6351b and the third swing arm 6353b are both installed on the frame 100b. The third swing arm 6353b and the transmission gear 6351b are meshed, that is to say, a driven gear 6354b is provided on the third swing arm 6353b to cooperate with the transmission gear 6351b. Specifically, when the transmission gear 6351b rotates, the third swing arm 6353b can swing under the action of the driven gear 6354b. The third swing arm 6353b is drivingly 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 second swing arm 632b swings to further realize the flipping of the second ice guiding plate 620b so that the second ice guiding plate 620b is located below the mold assembly 200b (see Figure 2 ). In this embodiment, when the linear driving structure 630b drives the driving plate 634b to move downward (see Figure 2), the driving teeth 6352b on the driving plate 634b can mesh with the transmission gear 6351b. As the driving plate 634b continues to move towards the second position, the transmission gear 6351b is rotated. During the rotation of the transmission gear 6351b, the third swing arm 6353b is driven to swing, so that the third swing arm 6353b drives the second swing arm 632b to swing, so as to realize 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 driving structure 630b drives the driving plate 634b to move upward (see Figure 1 ), at this time, the driving teeth 6352b drive the transmission gear 6351b to rotate, so that the third swing arm 6353b returns to the initial position. At this time, the second ice guide plate 620b returns to the initial state under the action of the torsion spring 633b, and thus is located outside the mold assembly 200b. At the same time, the driving plate 634b does not press down the first swing arm 631b, and the first ice guide plate 610b also returns to the initial state under the action of the torsion spring 633b, and thus is located outside the mold assembly 200b. Further, when the ice maker includes a collection box, when the linear driving structure 630b drives the driving plate 634b to move downward, the first ice guide plate 610b and the second ice guide plate 620b are located between the collection box and the mold assembly 200b.
