Description

Technical Field

[0001] This invention relates to the field of ice-making technology, and in particular to an ice-making mold, an ice-making device, and a refrigeration equipment. Background Technology

[0002] As lifestyle needs become more diverse, consumers are choosing to add ice to their drinks to improve the taste, leading to an increasing demand for ice making.

[0003] In existing technologies, ice is mainly made manually or automatically using ice-making molds. These molds typically consist of an upper mold assembly and a lower mold assembly that can be assembled together, forming a cavity for ice making. In practical applications, it has been found that a good waterproof seal cannot be achieved between the upper and lower mold assemblies. Water inside the cavity easily overflows through the gap between the upper and lower mold assemblies, negatively impacting the ice-making operation. Summary of the Invention

The upper mold assembly and the lower mold assembly are arranged opposite each other, and the boss structure is embedded in the groove structure so that the first mold cavity and the second mold cavity form a closed mold cavity. The opposing walls of the boss structure and the groove structure are sealed by a sealing structure to prevent water from flowing out of the mold cavity. In the event of failure of the sealing structure, water in the mold cavity can pass through the sealing structure to the guide section, and then flow through the guide section to the water supply assembly for supplying water to the mold cavity.

When the boss structure is embedded in the groove structure, the platform of the boss structure and the bottom surface of the groove structure are in contact, and the boss is embedded in the groove.

When the boss structure is embedded in the groove structure, the elastic sealing strip abuts against the groove wall surface of the groove structure on one side away from the boss structure.

[0013] According to one embodiment of the present invention, the ice-making mold further includes a driving component, the driving component being connected to the lower mold component to drive the lower mold component to switch between a first state and a second state relative to the upper mold component; When the lower mold assembly is in the first state, the upper mold assembly and the lower mold assembly are connected, and the first mold cavity and the second mold cavity form a closed mold cavity; When the lower mold assembly is in the second state, the upper mold assembly and the lower mold assembly are separated.

[0014] An ice-making apparatus according to a second aspect of the present invention includes: an ice-making mold and a water supply assembly; The ice-making mold is as described above, and the water supply component is configured to supply water to the cavity of the ice-making mold.

[0015] According to one embodiment of the present invention, the upper mold assembly is provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected to the first mold cavity; The water outlet is located at the top of the first mold cavity, and the water inlet is located on one side of the water outlet and is configured to tilt downwards towards the mold cavity to supply water.

[0018] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: The ice-making mold shown in this embodiment of the invention includes an upper mold assembly and a lower mold assembly that can be assembled together. Since the upper mold assembly and the lower mold assembly are assembled using a nested structure composed of a boss structure and a groove structure, the sealing structure between the opposing walls of the boss structure and the groove structure can be used to ensure good sealing performance between the upper mold assembly and the lower mold assembly. When the sealing structure fails, the nested structure limits the overflow in the mold cavity to an upward inclined path, and the overflowing water returns to the water supply assembly through the guide part, preventing water from flowing to other places besides the ice-making mold. Thus, this design not only ensures the reliable sealing performance of the ice-making mold, but also provides good overflow protection for water overflowing from the mold cavity when the seal fails.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0053] The following is combined Figures 1-26 The ice-making apparatus and refrigeration equipment provided in the embodiments of the invention will be described in detail through specific implementation methods and application scenarios.

[0054] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of the present invention provides an ice-making mold, including: an upper mold assembly 1 and a lower mold assembly 2; The lower surface of the upper mold assembly 1 is provided with a boss structure 1001, and the platform of the boss structure 1001 is provided with a first mold cavity 101; the upper surface of the lower mold assembly 2 is provided with a groove structure 2001, and the bottom surface of the groove structure 2001 is provided with a second mold cavity 102. The groove edge of the groove structure 2001 is provided with a guide portion extending towards the outside of the groove structure 2001; the upper mold assembly 1 and the lower mold assembly 2 are arranged opposite each other, and the boss structure 1001 is embedded in the groove structure 2001 so that the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10. The opposing walls of the boss structure 1001 and the groove structure 2001 are sealed by a sealing structure to prevent water from flowing out of the mold cavity 10; In the event of a seal failure, water within the mold cavity 10 can pass through the flow guide section of the seal and then flow through the flow guide section to the water supply assembly 6 used to supply water to the mold cavity 10. The flow guide section is located in... Figure 5 The letter D is used for identification. Figure 5 Arrows are used to illustrate the flow path of water overflowing from the mold cavity 10 of the ice-making mold when the sealing structure fails.

[0055] Understandably, for the upper mold assembly 1, the boss structure 1001 is constructed on the lower surface of the upper mold assembly 1 and protrudes vertically downward toward the outside of the upper mold assembly 1; for the lower mold assembly 2, the groove structure 2001 is constructed on the upper surface of the lower mold assembly 2 and is recessed vertically toward the inside of the lower mold assembly 2.

[0056] Meanwhile, the boss structure 1001 and the groove structure 2001 form a compatible nested structure. When the upper mold assembly 1 and the lower mold assembly 2 are assembled accordingly, the platform surface of the boss structure 1001 and the bottom surface of the groove structure 2001 are correspondingly fitted, and the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001 are correspondingly fitted, so that the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10. A sealing structure can be provided between the platform surface of the boss structure 1001 and the bottom surface of the groove structure 2001, and between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001. The sealing structure can be an elastic sealing ring.

[0057] As can be seen from the above, since the upper mold assembly 1 and the lower mold assembly 2 are assembled using a nested structure consisting of a boss structure 1001 and a groove structure 2001, the sealing structure between the relative walls of the boss structure 1001 and the groove structure 2001 can be used to ensure good sealing performance between the upper mold assembly 1 and the lower mold assembly 2. When the sealing structure fails, the nested structure limits the overflow in the mold cavity 10 to only flow along an upward inclined path, and the overflowing water will also return to the water supply assembly 6 through the guide part to prevent water from flowing to other places except the ice-making mold. Thus, this design not only ensures the reliable sealing performance of the ice-making mold, but also provides good overflow protection for the water overflowing from the mold cavity 10 when the seal fails.

[0058] In some embodiments, such as Figure 5 and Figure 6 As shown, the sealing structure includes a first sealing component 201, which is disposed between the platform of the boss structure 1001 and the bottom surface of the groove structure 2001, and extends circumferentially along the mold cavity 10.

[0059] Understandably, the first sealing component 201 can be configured in a ring shape, for example, the first sealing component 201 is an elastic sealing ring. As the first seal for preventing leakage of the mold cavity 10, the first sealing component 201 can effectively prevent water leakage from the mold cavity 10 by utilizing the sealing performance of the first sealing component 201.

[0060] In some embodiments, such as Figure 6 As shown, the first sealing assembly 201 includes: a protrusion and a groove; the protrusion and the groove extend circumferentially along the mold cavity 10 respectively; one of the protrusion and the groove is disposed on the platform of the boss structure 1001, and the other of the protrusion and the groove is disposed on the bottom surface of the groove structure 2001. When the boss structure 1001 is embedded in the groove structure 2001, the platform surface of the boss structure 1001 and the bottom surface of the groove structure 2001 are in contact, and the boss is embedded in the groove.

[0061] Understandably, based on the nested fit between the protrusion and the groove, while ensuring that the platform of the protrusion structure 1001 and the bottom surface of the groove structure 2001 fit together, a sealed connection is achieved between the platform of the protrusion structure 1001 and the bottom surface of the groove structure 2001. This facilitates the tight assembly of the first mold cavity 101 and the second mold cavity 102 into a complete mold cavity 10, thus ensuring the molding quality of the ice ball.

[0062] Furthermore, the portion of the upper mold assembly 1 corresponding to the boss structure 1001 and the portion of the lower mold assembly 2 corresponding to the groove structure 2001 can both be made of elastic material. When the upper mold assembly 1 and the lower mold assembly 2 are assembled together, the protrusion is embedded in the groove, and the peripheral wall of the protrusion abuts against the inner wall of the groove. This design further ensures the sealing effect of the first sealing assembly 201.

[0063] In some embodiments, such as Figure 6 As shown, in order to ensure the sealing effect of the mold cavity 10, the first sealing component 201 is provided in multiple sets. The multiple sets of first sealing components 201 are arranged from the inside to the outside relative to the mold cavity 10. Each set extends along the circumference of the mold cavity 10 and can be configured to be composed of protrusions and grooves that can be embedded together.

[0064] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, multiple mold cavities 10 are formed between the upper mold assembly 1 and the lower mold assembly 2, and multiple sets of first sealing assemblies 201 are provided. Each set of first sealing assemblies 201 is respectively arranged in correspondence with multiple mold cavities 10 to seal each mold cavity 10.

[0065] In some embodiments, such as Figure 5 and Figure 7 As shown, the sealing structure includes: a second sealing component 202; the second sealing component 202 is disposed between the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001, and extends circumferentially along the boss structure 1001.

[0066] Understandably, the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001 are both inclined surfaces that are inclined relative to the horizontal plane.

[0067] The second sealing assembly 202 can also be configured in an annular shape, for example, the second sealing assembly 202 is an elastic sealing ring. The second sealing assembly 202 is used to achieve a seal between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001.

[0068] The second sealing component 202 serves as a second seal to prevent leakage of the mold cavity 10. When multiple mold cavities 10 are provided between the platform of the boss structure 1001 and the bottom surface of the groove structure 2001, the second sealing component 202 can simultaneously serve as a second seal for multiple mold cavities 10. After the seal of the first sealing component 201 fails, the second sealing component 202 prevents the water overflowing from the mold cavity 10 from continuing to flow outward along the gap between the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001.

[0069] In some embodiments, such as Figure 5 and Figure 7 As shown, the second sealing assembly 202 includes: an elastic sealing strip; the elastic sealing strip is disposed on the peripheral wall of the boss structure 1001 and extends along the circumferential direction of the boss structure 1001; the elastic sealing strip is also disposed at an angle to the peripheral wall of the boss structure 1001 and extends upward at an angle toward the side away from the platform. When the boss structure 1001 is embedded in the groove structure 2001, the elastic sealing strip abuts against the groove wall surface of the groove structure 2001 on one side away from the boss structure 1001.

[0070] Understandably, since the part of the upper mold assembly 1 corresponding to the boss structure 1001 is usually made of elastic material, the elastic sealing strip and the boss structure 1001 can be set as an integral structure.

[0071] Because the gap between the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001 is smaller than the length of the elastic sealing strip along the direction perpendicular to the peripheral wall of the boss structure 1001, the elastic sealing strip will deform and abut against the groove wall of the groove structure 2001 when the upper mold assembly 1 and the lower mold assembly 2 are assembled. This effectively blocks the path of water flow outward along the gap between the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001. This design not only ensures the reliability of the seal between the peripheral wall of the boss structure 1001 and the groove wall of the groove structure 2001, but also eliminates the need for an additional second sealing component 202 during the assembly of the ice-making mold, making the operation simple and convenient.

[0072] In practical applications, in order to ensure the water-blocking sealing effect of the second seal, multiple elastic sealing strips can be set. The multiple elastic sealing strips are respectively set on the peripheral wall of the boss structure 1001 and arranged sequentially along the water overflow path from the mold cavity 10 to the outside of the ice-making mold.

[0073] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, this embodiment of the invention also provides an ice-making device, including: an ice-making mold, a water supply component 6, and a temperature control component 7; The ice-making mold has a mold cavity 10 and a water inlet 1011 and a water outlet 1012 communicating with the mold cavity 10. The water outlet 1012 is located at the top of the mold cavity 10, and the water inlet 1011 is located on one side of the water outlet 1012 and is inclined downward toward the mold cavity 10 to supply water. The water supply component 6 forms a circulating water system with the mold cavity 10 through the water inlet 1011 and the water outlet 1012; the temperature control component 7 is configured to be connected to the water supply component 6 to adjust the water temperature supplied by the water supply component 6 to the mold cavity 10.

[0074] Understandably, the ice-making mold is configured to connect to a cold source, and based on the cold energy provided by the cold source, the water in the mold cavity 10 condenses into ice blocks of a specific shape, the appearance of which is adapted to the shape of the mold cavity 10.

[0075] For example, the mold cavity 10 can be spherical, cylindrical, cubic, etc., and there is no specific limitation thereto. Since ice hockey is widely used in actual consumption, the design scheme of the embodiment of the present invention will be specifically described below using an ice hockey made based on a spherical mold cavity 10 as an example.

[0076] By placing the water outlet 1012 at the top of the mold cavity 10, it is possible to ensure that the mold cavity 10 is filled with water during the ice-making process, thus ensuring the integrity and consistency of the ice ball's shape.

[0077] Since the water supply component 6 and the mold cavity 10 form a circulating water system, this design ensures that the water in the mold cavity 10 is in a dynamic flow state. Compared with the static ice-making scheme, this design can remove air bubbles in the ice ball to a certain extent, making the ice ball transparent.

[0078] Furthermore, by placing the water inlet 1011 on one side of the water outlet 1012 and tilting it downwards towards the mold cavity 10 to supply water, this design can use the disturbance effect of the incoming water flow to drive the water to flow in the mold cavity 10 during the ice-making process, so as to promote the precipitation of air bubbles in the water and prevent the appearance of the formed ice ball from being affected by the inclusion of air bubbles.

[0079] Thus, based on the design of the inlet 1011 and the outlet 1012, a transparent ice ball that matches the shape of the mold cavity 10 can be prepared by using an ice-making mold.

[0080] Considering that during the ice-making process, if the water temperature is too high, the high-temperature water entering the mold cavity 10 will affect the freezing speed, or even prevent freezing altogether, and if the water temperature is too low, the freezing speed will be too fast and the air bubbles in the water will not be able to be released in time, resulting in the inability to produce transparent ice, this embodiment of the invention uses a temperature control component 7 to regulate the water temperature in the water system.

[0081] Since the temperature control component 7 is configured to regulate the temperature of the water flowing in the water system, this design can use the temperature control component 7 to control the water supply temperature of the water supply component 6 to the mold cavity 10, which not only promotes the precipitation of air bubbles in the water, but also ensures the freezing speed in the mold cavity 10.

[0082] For example, during the ice-making process, the temperature control component 7 controls the water temperature supplied from the water supply component 6 to the mold cavity 10 between 0°C and 2°C; the temperature control component 7 includes at least one of a heating wire and a semiconductor cooling chip. As can be seen from the above, by setting an ice-making mold, a water supply component 6, and a temperature control component 7 in the ice-making device, during the ice-making process, the water supply component 6 and the mold cavity 10 form a circulating water system. This ensures that the mold cavity 10 is filled with water while maintaining a dynamic flow state. Furthermore, based on the temperature control component 7's regulation of the water temperature within the mold cavity 10, it not only promotes the release of air bubbles in the water but also ensures the freezing speed within the mold cavity 10. This design allows for the preparation of transparent ice based on the ice-making mold and ensures ice-making efficiency.

[0083] Of course, in some application scenarios, compared with the static ice-making scheme, as long as the transparency and integrity of the prepared ice ball are improved to a certain extent, the ice-making device can also be configured to include the ice-making mold and water supply component 6 as described above. The water supply component 6 is configured to supply water to the mold cavity 10 of the ice-making mold, or it is not necessary to set the water supply component 6 and the mold cavity 10 as a circulating water system.

[0084] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the ice-making mold includes: an upper mold assembly 1, a lower mold assembly 2, and a drive assembly 3; The upper mold assembly 1 is provided with a first mold cavity 101 and an inlet 1011 and an outlet 1012 communicating with the first mold cavity 101; the lower mold assembly 2 is provided with a second mold cavity 102; the driving assembly 3 is connected to the lower mold assembly 2 to drive the lower mold assembly 2 to switch between a first state and a second state relative to the upper mold assembly 1. When the lower mold assembly 2 is in the first state, the upper mold assembly 1 and the lower mold assembly 2 are connected, and the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10; when the lower mold assembly 2 is in the second state, the upper mold assembly 1 and the lower mold assembly 2 are separated.

[0085] Understandably, both the first mold cavity 101 and the second mold cavity 102 are open, with the first mold cavity 101 formed on the lower surface of the upper mold assembly 1 and the second mold cavity 102 formed on the upper surface of the lower mold assembly 2; wherein, when the mold cavity 10 is a spherical cavity, both the first mold cavity 101 and the second mold cavity 102 are hemispherical.

[0086] In practical applications, the upper mold assembly 1 and the drive assembly 3 are respectively located on the frame 4. The drive assembly 3 is connected to the lower mold assembly 2 to drive the lower mold assembly 2 to rise or fall or flip relative to the upper mold assembly 1, so as to control the lower mold assembly 2 to switch between the first state and the second state relative to the upper mold assembly 1.

[0087] like Figure 1As shown, when the lower mold assembly 2 is in the first state, the lower mold assembly 2 is located below the upper mold assembly 1, and the lower surface of the upper mold assembly 1 and the upper surface of the lower mold assembly 2 are connected, so that the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10.

[0088] like Figure 3 As shown, when the lower mold assembly 2 is in the second state, the lower mold assembly 2 is flipped to one side of the upper mold assembly 1 under the drive of the drive assembly 3, so that the upper mold assembly 1 and the lower mold assembly 2 are separated.

[0089] For example, such as Figure 1 As shown, the drive assembly 3 includes a drive motor 31, a transmission shaft 32, and a transmission arm 33. The drive motor 31 is mounted on the frame 4, and the transmission shaft 32 is rotatably mounted on the frame 4. The drive motor 31 and the transmission shaft 32 are connected. The transmission shaft 32 is connected to the first end of the transmission arm 33, and the second end of the transmission arm 33 is connected to the lower mold assembly 2.

[0090] Meanwhile, the lower mold assembly 2 is rotatably mounted on the frame 4 via a hinge shaft. When the drive motor 31 is started, the drive motor 31 drives the transmission shaft 32 to rotate, the transmission shaft 32 drives the transmission arm 33 to swing, and then the transmission arm 33 drives the lower mold assembly 2 to rotate around the hinge shaft, thereby driving the lower mold assembly 2 to switch between the first state and the second state relative to the upper mold assembly 1.

[0091] Furthermore, such as Figure 2 and Figure 24 As shown, a floating frame 24 is provided at the bottom of the lower mold assembly 2. The floating frame 24 includes an elastic element 241 and a frame body 242. The elastic element 241 is located between the lower mold assembly 2 and the frame body 242. The second end of the transmission arm 33 is rotatably connected to the frame body 242. In this way, when the drive assembly 3 drives the lower mold assembly 2 to switch from the second state to the first state, it ensures that the lower mold assembly 2 contacts the upper mold assembly 1 under the elastic force of the elastic element 241, and then assembles them into one piece. This design can not only avoid damage to the upper mold assembly 1 and the lower mold assembly 2 due to mutual collision, but also ensure the sealing effect between the upper mold assembly 1 and the lower mold assembly 2 during the ice-making process.

[0092] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, an embodiment of the present invention provides an ice-making device, including: a frame 4, a flow guide 5, and the ice-making mold as described above; The guide 5 is configured to be located on one side of the ice-making mold and is movably located on the water supply assembly 6, which is used to supply water to the ice-making mold. The ice-making mold includes an upper mold assembly 1, a lower mold assembly 2, and a drive assembly 3, and has an overflow port formed between the upper mold assembly 1 and the lower mold assembly 2; the upper mold assembly 1 and the drive assembly 3 are respectively disposed on the frame 4, and a sealing structure is provided between the opposite walls of the upper mold assembly 1 and the lower mold assembly 2; the drive assembly 3 is connected to the lower mold assembly 2 to drive the lower mold assembly 2 to switch between a first state and a second state relative to the upper mold assembly 1. When the lower mold assembly 2 is in the first state, the upper mold assembly 1 is sealed to the lower mold assembly 2 through a sealing structure, and the lower mold assembly 2 and the guide 5 abut against each other so that the overflow port and the guide 5 are arranged opposite each other; when the lower mold assembly 2 is in the second state, the upper mold assembly 1 and the lower mold assembly 2 are separated, and the lower mold assembly 2 and the guide 5 are separated. In the event of a seal failure, water inside the ice-making mold can pass through the seal to the overflow port, then flow from the overflow port to the guide component 5, and finally, guided by the guide component 5, flow to the water supply assembly 6. The overflow port is located in... Figure 5 The letter X is used for identification. Figure 5 Arrows are used to illustrate the flow path of water overflowing from the mold cavity 10 of the ice-making mold when the sealing structure fails.

[0093] Understandably, the sealing structure can be an elastic sealing ring or the like, and the sealing structure is configured to extend circumferentially along the cavity 10 of the ice-making mold to prevent water leakage within the cavity 10.

[0094] Since the lower surface of the upper mold assembly 1 is provided with a first mold cavity 101 and the upper surface of the lower mold assembly 2 is provided with a second mold cavity 102, when the lower mold assembly 2 is in the first state, the upper mold assembly 1 and the lower mold assembly 2 are assembled, and the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10. The sealing structure is sandwiched between the lower surface of the upper mold assembly 1 and the upper surface of the lower mold assembly 2 to achieve a waterproof seal for the mold cavity 10 in the circumferential direction.

[0095] Meanwhile, the overflow port is located at the end of the ice-making mold closest to the water supply component 6. Only when the lower mold component 2 is in the first state, the upper mold component 1 and the lower mold component 2 are assembled as one unit, and an overflow port is formed between the upper mold component 1 and the lower mold component 2. In actual operation, if the sealing structure does not fail, the mold cavity 10 will not leak water under the sealing effect of the sealing structure. If the sealing structure fails, the water in the mold cavity 10 will flow along the gap between the relative walls of the upper mold component 1 and the lower mold component 2, and pass through the sealing structure during the flow, and then flow to the overflow port. Then, it flows through the overflow port to the guide component 5, and then flows to the water supply component 6 under the guidance of the guide component 5. This design realizes the recycling of water overflowing from the mold cavity 10 and prevents water from flowing to other places except the ice-making mold.

[0096] During the process of switching from the second state to the first state, the lower mold assembly 2 flips towards the side closer to the upper mold assembly 1. During the flipping process, the lower mold assembly 2 will come into contact with the guide component 5 and drive the guide component 5 to move. When the upper mold assembly 1 and the lower mold assembly 2 are assembled, the guide component 5 is exactly below the overflow port.

[0097] Correspondingly, during the process of switching the lower mold assembly 2 from the first state to the second state, the lower mold assembly 2 flips towards the side away from the upper mold assembly 1. During the flipping process, the lower mold assembly 2 will separate from the guide component 5. At this time, since the upper mold assembly 1 and the lower mold assembly 2 are separated and the ice ball is demolded, there is no longer an overflow port between the upper mold assembly 1 and the lower mold assembly 2, and the guide component 5 will not play a role in guiding the flow.

[0098] like Figure 1 and Figure 4 As shown, the water supply assembly 6 is mounted on the frame 4. The water supply assembly 6 includes a water tank 61, a water pump 62, and a water supply pipeline 63. The water pump 62 and the water supply pipeline 63 are connected. The water supply pipeline 63 is located between the water tank 61 and the mold cavity 10. The water pump 62 is used to deliver the water in the water tank 61 to the mold cavity 10.

[0099] like Figure 5 As shown, the guide member 5 is configured to be movably mounted on the water tank 61. During the process of the lower mold assembly 2 switching from the second state to the first state, the guide member 5 can be configured to translate relative to the water tank 61 in a vertical plane under the drive of the lower mold assembly 2, or it can be configured to translate relative to the water tank 61 in a horizontal plane under the drive of the lower mold assembly 2. There is no specific limitation on this, as long as the overflow port and the guide member 5 are arranged vertically opposite each other when the upper mold assembly 1 and the lower mold assembly 2 are assembled, and the guide member 5 can be used to guide the water overflowing from the overflow port.

[0100] As can be seen from the above, the ice-making device shown in the embodiment of the present invention, by setting a guide 5 on one side of the ice-making mold and movably setting the guide 5 on the water supply component 6, allows the ice-making mold to close towards the upper mold component 1 under the control of the lower mold component 2 by the drive component 3. The guide 5 can be driven by the lower mold component 2 to move relative to the water supply component 6 until the guide 5 reaches the lower side of the overflow port. Thus, when the sealing structure fails, the guide 5 can guide the water overflowing from the overflow port to the water supply component 6, realizing the recovery of the overflow water and preventing water from flowing to other places besides the ice-making mold.

[0101] In some embodiments, such as Figure 4 and Figure 10As shown, the guide member 5 is movably disposed on the water supply component 6 along a first direction, which is inclined relative to the horizontal plane; when the lower mold component 2 is in the first state, the guide member 5 is close to the lower mold component 2 and located at a first height; when the lower mold component 2 is in the second state, the guide member 5 can fall to a position away from the lower mold component 2 and located at a second height under its own gravity; wherein, the first height is greater than the second height.

[0102] Understandably, the first direction is an inclined direction relative to the horizontal plane, and the angle of inclination of the first direction relative to the horizontal plane can be 30º to 60º. The guide member 5 is movably disposed on the water tank 61 along the first direction.

[0103] During the process of the lower mold assembly 2 flipping from the second state to the first state, the lower mold assembly 2 drives the guide 5 to move upward relative to the water tank 61 and gradually approach the overflow port in the horizontal direction. When the upper mold assembly 1 and the lower mold assembly 2 are assembled, the guide 5 stops at the position of the first height and is exactly below the overflow port.

[0104] Correspondingly, during the process of the lower mold assembly 2 flipping from the first state to the second state, the lower mold assembly 2 separates from the guide member 5 during the flipping process. The guide member 5 can move downward relative to the water tank 61 under its own gravity and gradually move away from the overflow port in the horizontal direction until the guide member 5 stops at the second height position. At this time, the position of the guide member 5 is far away from the flipping path of the lower mold assembly 2, so it will not affect the flipping movement of the lower mold assembly 2.

[0105] In some embodiments, such as Figure 4 and Figure 5 As shown, in order to better guide the water overflowing from the overflow port into the water tank 61, at least part of the guide member 5 is inclined downward toward the side away from the ice-making mold.

[0106] For example, when the lower mold assembly 2 is in the first state, the portion of the guide member 5 that overlaps with the overflow port in the vertical direction can be configured to extend downward at an angle toward the side away from the ice-making mold.

[0107] In some embodiments, such as Figure 8 and Figure 9 As shown, the lower mold assembly 2 has a first inclined surface P1, and the flow guide 5 has a second inclined surface P2; wherein, the first inclined surface P1 can contact the second inclined surface P2 and abut against the lower side of the second inclined surface P2, so as to drive the flow guide 5 to move relative to the water supply assembly 6 in the first direction.

[0108] Understandably, since the lower mold assembly 2 and the flow guide 5 are slidably engaged with the second inclined plane P2 through the first inclined plane P1, the lower mold assembly 2 can apply horizontal and vertical force to the flow guide 5 through the first inclined plane. This force setting not only satisfies the requirement of the lower mold assembly 2 to rotate relative to the upper mold assembly 1, but also ensures that the flow guide 5 can be moved relative to the water tank 61 along the first direction through the lower mold assembly 2.

[0109] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the flow guide 5 includes: a flow guide plate 51 and an ear seat 52; the flow guide plate 51 extends downward at an incline toward the side away from the ice-making mold; the ear seat 52 is connected to the flow guide plate 51 and slides in cooperation with the water supply assembly 6 along the first direction, and the ear seat 52 is provided with a second inclined surface P2; wherein, the lower mold assembly 2 is provided with a support 2002, the support 2002 is provided with a first inclined surface P1, and the support 2002 and the ear seat 52 can slide in cooperation through the first inclined surface P1 and the second inclined surface P2.

[0110] Specifically, the ear base 52 is provided with an inner cavity, which is set with its opening facing downwards, and a second inclined surface is formed on the inner wall surface of the inner cavity on the side near the ice-making mold.

[0111] In practical applications, at least part of the support 2002 extends into the inner cavity. The support 2002 uses its first inclined surface to slide and engage with the second inclined surface inside the ear seat 52. This design achieves a compact fit between the guide 5 and the lower mold assembly 2, reducing the space occupied.

[0112] In some embodiments, such as Figure 10 and Figure 11 As shown, the ear seat 52 is provided with a sliding shaft 53, and the water supply component 6 is provided with a strip hole 610. The strip hole 610 extends along the first direction, and the sliding shaft 53 is movably inserted into the strip hole 610.

[0113] Specifically, the strip-shaped hole 610 is provided on the water tank 61, and the sliding shaft 53 is provided at the end of the ear seat 52 away from the guide plate 51. The sliding shaft 53 can be a flat shaft, and the thickness of the flat shaft is adapted to the width of the strip-shaped hole 610. This design can ensure that the sliding shaft 53 can only move relative to the strip-shaped hole 610 along the extension direction of the strip-shaped hole 610, and cannot rotate within the strip-shaped hole 610.

[0114] In some embodiments, such as Figure 10 and Figure 11As shown, in order to ensure the stability of the flow guide 5 relative to the water tank 61, there are two ear seats 52, which are spaced apart from each other and arranged side by side; the flow guide plate 51 is located between the two ear seats 52; there are two supports 2002, which are spaced apart from each other and are respectively arranged opposite to the two ear seats 52.

[0115] In some embodiments, such as Figure 12 , Figure 13 , Figure 15 and Figure 21 As shown, an embodiment of the present invention provides an upper mold assembly 1, including: a water collection tank 12, an upper mold shell 11, and an adapter 13; The bottom of the water collection tank 12 is provided with a water outlet 122; the upper mold shell 11 is located on the lower side of the water collection tank 12, and the side of the upper mold shell 11 away from the water collection tank 12 is provided with a first mold cavity 101, and the side of the upper mold shell 11 facing the water collection tank 12 is provided with a water outlet 1012 and a sealing part 1120 extending circumferentially along the water outlet 1012. The first mold cavity 101 is connected to the water outlet 1012 and the water outlet 122, and the sealing part 1120 is sealed to the bottom of the water collection tank 12; the adapter 13 is connected to the water collection tank 12, and the sealing part 1120 is clamped between the bottom of the water collection tank 12 and the adapter 13.

[0116] Understandably, the sealing part 1120 can be configured as circular, with the water outlet 1012 located at the center of the sealing part 1120 and configured to be coaxially connected with the water outlet 122 on the water collection tank 12, so that the first mold cavity 101 can be connected through the water outlet 1012 and the water outlet 122.

[0117] A sealant and other sealing structures can be provided between the upper surface of the sealing part 1120 and the bottom surface of the water collection tank 12 to achieve a sealed connection between the sealing part 1120 and the bottom of the water collection tank 12. Meanwhile, the first mold cavity 101 can be provided with an inlet 1011 communicating with the first mold cavity 101, and an outlet 1012 located at the top of the first mold cavity 101 and communicating with the outlet hole 122 at the bottom of the water collection tank 12.

[0118] In addition, the adapter 13 can be made of a material with a hardness greater than that of the sealing part 1120. The adapter 13 is connected to the bottom of the water collection tank 12 by locking parts such as screws and bolts.

[0119] As can be seen from the above, the upper mold assembly 1 shown in this embodiment of the invention, by providing a sealing part 1120 extending circumferentially along the outlet 1012 of the upper mold shell 11, can achieve a waterproof seal for the outlet 1012 based on the sealing connection between the sealing part 1120 and the bottom of the water collection tank 12 when the outlet 1012 is connected to the outlet hole 122 of the water collection tank 12. Furthermore, by connecting the adapter 13 to the water collection tank 12 and clamping the sealing part 1120 between the bottom of the water collection tank 12 and the adapter 13, the connection between the water collection tank 12 and the upper mold shell 11 is achieved. This design not only completes the assembly of the water collection tank 12 and the upper mold shell 11, but also ensures a waterproof seal between the water collection tank 12 and the upper mold shell 11, ensuring that the water in the first mold cavity 101 can overflow into the water collection tank 12 and will not flow into the gap between the water collection tank 12 and the upper mold shell 11.

[0120] In some embodiments, such as Figure 15 As shown, the adapter 13 includes: a base 131 and an adapter post 132; the base 131 is provided with a through hole and is sleeved on the peripheral wall of the water outlet 1012 through the through hole; the sealing part 1120 is clamped between the bottom of the water collection tank 12 and the base 131; the adapter post 132 is connected to the base 131 and is provided on the side of the base 131 facing the water collection tank 12, and the adapter post 132 is connected to the bottom of the water collection tank 12.

[0121] In order to facilitate the clamping of the sealing part 1120, the base 131 is provided with a positioning groove on the side facing the water collection tank 12, and at least part of the sealing part 1120 is embedded in the positioning groove. The sealing part 1120 is clamped between the bottom of the water collection tank 12 and the bottom of the positioning groove.

[0122] In some embodiments, such as Figure 13 and Figure 21 As shown, the water collection tank 12 includes: a fixed column 121; the fixed column 121 is disposed in the water collection tank 12, the fixed column 121 has a plug-in cavity and a through hole communicating with the plug-in cavity, the plug-in cavity is open on the side facing the bottom of the tank, and the through hole is located at the top of the fixed column 121; a connecting column 132 is inserted into the plug-in cavity; the fixed column 121 is connected to the connecting column 132 through a locking member passing through the through hole.

[0123] In practical applications, the base 131 of the adapter 13 is first fitted onto the periphery of the outlet 1012, the water collection tank 12 is placed on the upper side of the upper mold shell 11, and the adapter post 132 of the adapter 13 is inserted into the insertion cavity of the fixed post 121. Then, a locking member is inserted through the through hole of the fixed post 121 and connected to the adapter post 132 to assemble the water collection tank 12, the upper mold shell 11 and the adapter 13 into one unit. The operation is simple and convenient.

[0124] The locking component can be a locking screw. The adapter 13 is provided with a locking screw hole. The screw of the locking screw is threaded into the locking screw hole, so that the fixing post 121 and the adapter post 132 can be connected into one unit by using the locking screw.

[0125] In some embodiments, such as Figure 12 and Figure 15 As shown, in order to ensure the reliability of fixing the sealing part 1120, the base 131 is provided with a plurality of adapter posts 132, which are arranged around the through hole; the water collection tank 12 is provided with a plurality of fixing posts 121 arranged around the water outlet 122, and the plurality of adapter posts 132 are connected to the plurality of fixing posts 121 one by one.

[0126] In some embodiments, such as Figure 13 As shown, the height of the fixed column 121 is greater than the height of the rim of the water collection tank 12. This design can prevent water in the water collection tank 12 from overflowing into the fixed column 121.

[0127] In some embodiments, such as Figure 13 As shown, in order to ensure the sealing effect between the sealing part 1120 and the bottom of the water collection tank 12, the side of the sealing part 1120 facing the water collection tank 12 is in contact with the bottom surface of the water collection tank 12, and a sealing structure 1101 is provided between the sealing part 1120 and the opposite wall surface of the water collection tank 12. The sealing structure 1101 includes a sealing groove and a sealing rib. The sealing rib is embedded in the sealing groove. Both the sealing groove and the sealing rib extend circumferentially along the outlet 1012. One of the sealing groove and the sealing rib is located at the bottom of the groove, and the other of the sealing groove and the sealing rib is located at the sealing part 1120.

[0128] In some embodiments, such as Figure 12 and Figure 13 As shown, the upper mold assembly 1 includes an upper mold shell 11 and a first heating element 14; the upper mold shell 11 is provided with a first mold cavity 101, a water inlet 1011 and a water outlet 1012; the first heating element 14 is disposed on the upper mold shell 11 and arranged around the first mold cavity 101.

[0129] Understandably, the first heating element 14 is arranged on the outside of the first mold cavity 101 and is arranged around the first mold cavity 101. When demolding the ice ball, the first heating element 14 can be used to heat the upper mold shell 11 to ensure that the peripheral wall of the ice ball is separated from the inner wall of the first mold cavity 101, thereby realizing the separation of the ice ball from the upper mold shell 11.

[0130] Optionally, the first heating element 14 can be an electric heating wire.

[0131] Optionally, two sets of first heating elements 14 can be provided, with the two sets of first heating elements 14 distributed vertically. The set of first heating elements 14 located on the upper side is arranged around the outlet 1012, and the set of first heating elements 14 located on the upper side is arranged around the peripheral wall of the first mold cavity 101.

[0132] In some embodiments, such as Figure 13 and Figure 14 As shown, the upper mold shell 11 includes: a first fixed frame 111 and a first elastic mold shell 112; the first elastic mold shell 112 is detachably disposed on the first fixed frame 111, and the first mold cavity 101, the water inlet 1011 and the water outlet 1012 are respectively constructed on the first elastic mold shell 112. The first mold cavity 101 can form a closed mold cavity 10 with the second mold cavity 102 in the lower mold assembly 2, and at least a portion of the bottom wall of the second mold cavity 102 is configured to be connected to a cold source.

[0133] Understandably, by configuring the upper mold shell 11 with the first elastic mold shell 112, the first elastic mold shell 112 can contact the lower mold assembly 2, ensuring the sealing effect between the upper mold assembly 1 and the lower mold assembly 2.

[0134] Meanwhile, since the first elastic mold shell 112 is usually made of plastic materials such as silicone, the thermal conductivity of the first elastic mold shell 112 is relatively poor. Since at least part of the bottom wall of the second mold cavity 102 is configured to be connected to the cold source, the freezing process in the mold cavity 10 can be ensured to be from bottom to top during the ice-making process. This design can ensure that the rate of bubble release in the water in the mold cavity 10 is greater than the freezing rate of the water, thereby ensuring the transparency of the prepared ice ball.

[0135] In some embodiments, the sealing portion 1120 and the first elastic mold shell 112 are integral elastic components.

[0136] Understandably, the sealing part 1120 and the first elastic mold shell 112 can be an integral silicone component.

[0137] Since the sealing part 1120 is elastic, it can be configured to be clamped between the bottom of the water collection tank 12 and the adapter 13 in an interference fit. This design helps to ensure the sealing effect of the sealing part 1120 on the water outlet 1012.

[0138] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, this embodiment of the invention also provides an upper mold assembly 1, including: a water collection tank 12 and an upper mold shell 11 as described above; The water collection tank 12 is configured to transport water in the water collection tank 12 to the water supply component 6; The upper mold shell 11 is located on the lower side of the water collection tank 12; the upper mold shell 11 has a first mold cavity 101 and a water inlet 1011 and a water outlet 1012 communicating with the first mold cavity 101; the first mold cavity 101 is open to the lower side of the upper mold shell 11; the water inlet 1011 is configured to communicate with the water supply component 6; the water outlet 1012 is located at the top of the first mold cavity 101 and communicates with the water collection tank 12; The inlet 1011 is located on one side of the outlet 1012, and the inlet 1011 extends downward at an angle relative to the horizontal plane.

[0139] Understandably, the upper mold assembly 1 and the lower mold assembly 2 are used together. When the upper mold assembly 1 and the lower mold assembly 2 are assembled, the first mold cavity 101 of the upper mold assembly 1 and the second mold cavity 102 of the lower mold assembly 2 form a closed mold cavity 10.

[0140] like Figure 13 As shown, by placing the water outlet 1012 at the top of the mold cavity 10, it is possible to ensure that the mold cavity 10 is filled with water during the ice-making process, thus ensuring the integrity and consistency of the ice ball's shape.

[0141] like Figure 13 As shown, by placing the water inlet 1011 on one side of the water outlet 1012 and tilting it downwards towards the mold cavity 10 to supply water, for example, the angle between the water inlet 1011 and the vertical plane is α, where α ranges from 30º to 75º. Specifically, the tilt angle of the water inlet 1011 relative to the horizontal plane is 90º-α. This design ensures that the water flow during ice making scours the bottom wall of the mold cavity 10, using the disturbance effect of the water flow to drive the water up and down within the mold cavity 10, thereby promoting the precipitation of air bubbles in the water and preventing the formed ice balls from being affected by air bubbles.

[0142] Thus, based on the design of the inlet 1011 and the outlet 1012, a transparent ice ball that matches the shape of the mold cavity 10 can be prepared by using an ice-making mold.

[0143] Since the water supply component 6 is connected to the water inlet 1011 of the first mold cavity 101, and the water outlet 1012 of the first mold cavity 101 is connected to the water collection tank 12, and the water collection tank 12 is configured to transport water to the water supply component 6, the water supply component 6, the first mold cavity 101 and the water collection tank 12 can form a circulating water path. This design can ensure that the water in the mold cavity 10 is in a dynamic flow state. Compared with the static ice-making scheme, the embodiment of the present invention can remove air bubbles in the ice ball to a certain extent, so that the ice ball appears transparent.

[0144] As can be seen from the above, the upper mold assembly 1 of the present invention, by setting a water collection tank 12 on the upper side of the upper mold shell 11, optimizes the water inlet direction of the water inlet 1011 corresponding to the first mold cavity 101 and the position of the water outlet 1012. During the ice-making process, it can ensure the water circulation in the mold cavity 10 by forming a circulating water path based on the water supply assembly 6, the first mold cavity 101 and the water collection tank 12, and also ensure that the mold cavity 10 is filled with dynamically flowing water by utilizing the disturbance of the water inlet flow. This design allows air bubbles in the water in the mold cavity 10 to be continuously released during the ice-making process, ensuring the integrity and consistency of the ice forming shape, and can produce transparent ice balls that are adapted to the shape of the mold cavity 10.

[0145] In some embodiments, on the horizontal projection plane, the water inlet direction of the inlet 1011 is set at an angle relative to the direction of the line connecting the inlet 1011 and the outlet 1012.

[0146] Understandably, while the water inlet 1011 is set to extend downwards at an angle relative to the horizontal plane, the water inlet 1011 is also set to be angled relative to the line connecting the water inlet 1011 and the water outlet 1012. This design can utilize the disturbance effect of the incoming water flow to drive the water to rotate within the mold cavity 10, thereby accelerating the precipitation of air bubbles in the water.

[0147] In some embodiments, in order to improve water intake efficiency and accelerate the precipitation of water bubbles in the mold cavity 10, multiple water inlets 1011 are provided, and the multiple water inlets 1011 are arranged around the water outlet 1012; on the horizontal projection plane, at least some of the water intake directions of the multiple water inlets 1011 have different angles relative to the direction of the line connecting the water inlet 1011 and the water outlet 1012.

[0148] Specifically, the angle between the water inlet direction of each inlet 1011 and the direction of the line connecting the inlet 1011 and the outlet 1012 can be configured to be different. However, each inlet 1011 is used to drive the water to rotate in the same direction within the mold cavity 10.

[0149] Since multiple inlets 1011 simultaneously supply water into the mold cavity 10, by setting the water inlet direction of each inlet 1011, the water flow formed by different inlets 1011 can cooperate with each other to jointly drive the water to rotate in the mold cavity 10, ensuring that the mold cavity 10 is filled with dynamically flowing water and improving the efficiency of bubble release in the water in the mold cavity 10.

[0150] In some embodiments, in order to facilitate stable rotation of water within the mold cavity 10, the outlet 1012 extends vertically, and a plurality of inlets 1011 are centrally symmetrically distributed with respect to the axis of the outlet 1012.

[0151] For example, such as Figure 14 As shown, there are two inlets 1011, which are located on both sides of the outlet 1012. The two inlets 1011 are centrally symmetrical about the axis of the outlet 1012. The water inlet direction of each inlet 1011 is inclined downward relative to the horizontal plane, and is also set at an angle to the direction of the line connecting the inlet 1011 and the outlet 1012 on the horizontal projection plane.

[0152] In some embodiments, such as Figure 14 and Figure 21 As shown, the water collection tank 12 has a flow guide 120, which is used to guide the water in the water collection tank 12 to the water supply component 6.

[0153] Specifically, the guide port 120 is constructed on the wall of the end of the water collection tank 12 facing the water supply component 6. Under the guiding effect of the guide port 120, the water in the water collection tank 12 will be transported to the water supply component 6 instead of flowing to other places.

[0154] The water supply component 6 supplies water to the mold cavity 10 through the water inlet 1011. The water in the mold cavity 10 overflows from the water outlet 1012 into the water collection tank 12. The water in the water collection tank 12 then returns to the water supply component 6 through the guide port 120, realizing the circulation of water.

[0155] In some embodiments, such as Figure 14 and Figure 21 As shown, in order to facilitate the diversion of water in the water collection tank 12 to the water supply component 6, a guide edge is provided at the guide port 120. The guide edge is located on one side of the upper mold shell 11 and extends downward towards the water supply component 6.

[0156] In some embodiments, the upper mold assembly 1 further includes: a first temperature sensor 1102; the first temperature sensor 1102 is disposed on the upper mold shell 11 and located on one side of the first mold cavity 101; the first temperature sensor 1102 is used to collect temperature information inside the first mold cavity 101. The temperature information fed back by the first temperature sensor 1102 facilitates real-time monitoring of the icing situation inside the mold cavity 101.

[0157] In some embodiments, such as Figure 4 , Figure 18 and Figure 19 As shown, this embodiment of the invention also provides a water system, including: a water tank 61, a water collection tank 12, a water pump 62, and a water supply pipeline 63; The water collection tank 12 is configured to be located on the upper side of the ice-making mold and to communicate with the mold cavity 10 inside the ice-making mold; the water collected in the water collection tank 12 is configured to flow into the water tank 61; The water pump 62 is connected to the water supply pipeline 63, which is located between the water tank 61 and the mold cavity 10. The water pump 62 is used to send the water in the water tank 61 to the mold cavity 10.

[0158] It is understood that the water system consists of the water supply component 6 and the water collection tank 12 shown in the above embodiment. The water supply component 6 includes a water tank 61, a water pump 62 and a water supply pipeline 63. The water collection tank 12 is installed at a height higher than the water tank 61, and the water pump 62 is located at the bottom of the water tank 61.

[0159] Optionally, the inlet of the water pump 62 is connected to the water tank 61, the outlet of the water pump 62 is connected to the first end of the water supply pipe 63, the second end of the water supply pipe 63 is connected to the inlet 1011 of the mold cavity 10, and the outlet 1012 of the mold cavity 10 is connected to the water collection tank 12.

[0160] Water tank 61 can be configured to be connected to the frame 4 of the ice-making device. Water tank 61 is configured to be covered inside the heat insulation cover 71 to ensure that the temperature inside water tank 61 is maintained between 0℃ and 2℃. This design ensures the release of air bubbles in the water without affecting the freezing speed of water in the mold cavity 10.

[0161] The water system shown in this embodiment of the invention configures the ice-making mold with a water tank 61, a water collection tank 12, a water pump 62, and a water supply pipeline 63. Under the pumping of the water pump 62, the water in the water tank 61 reaches the water inlet 1011 along the water supply pipeline 63, and then enters the mold cavity 10 through the water inlet 1011. The water in the mold cavity 10 overflows from the water outlet 1012 into the water collection tank 12, and then the water in the water collection tank 12 returns to the water tank 61, thereby realizing the circulation of water. Compared with the static ice-making design, this design ensures that the mold cavity 10 is filled with dynamically flowing water during the ice-making process, which is conducive to ensuring the precipitation of air bubbles in the water in the mold cavity 10, and realizing the preparation of transparent ice that is adapted to the shape of the mold cavity 10 based on the ice-making mold.

[0162] In some embodiments, such as Figure 19 As shown, the water supply pipeline 63 includes a main pipeline 631, a first branch pipeline 632, and a second branch pipeline 633; ​​the first end of the main pipeline 631 is connected to the water tank 61, and the second end of the main pipeline 631 is connected to the first branch pipeline 632 and the second branch pipeline 633 respectively; the water pump 62 is installed on the main pipeline 631, the first branch pipeline 632 is connected to the water tank 61, and the second branch pipeline 633 is connected to the mold cavity 10.

[0163] Understandably, during the ice-making process, as the water in the mold cavity 10 continues to freeze, the end of the second branch pipe 633 near the mold cavity 10 will also freeze. In order to prevent the water pump 62 from freezing during operation, the main pipe 631 is connected to the water tank 61 through the first branch pipe 632.

[0164] At the same time, a first control valve can be installed on the first branch pipe 632 and a second control valve can be installed on the second branch pipe 633. The conduction status of the water supply pipe 63 can be controlled by the first control valve and the second control valve.

[0165] During the initial ice-making stage, water from tank 61 is pumped by pump 62, flowing sequentially along main pipe 631 and second branch pipe 633 into mold cavity 10, and then returning to tank 61 via collection tank 12. Of course, during the initial ice-making stage, water from tank 61 can also return to tank 61 sequentially along main pipe 631 and first branch pipe 632.

[0166] At the end of the ice-making process, as the water in the mold cavity 10 condenses into ice, the end of the second branch pipe 633 near the mold cavity 10 will also freeze. At this time, under the pumping of the water pump 62, the water in the water tank 61 can only flow along the main pipe 631 and the second branch pipe 633 in sequence, and return to the water tank 61 through the second branch pipe 633.

[0167] In some embodiments, the second branch pipe 633 includes a heat-conducting pipe and a heating element connected to the heat-conducting pipe; one end of the second branch pipe 633 near the ice-making mold is connected to the mold cavity 10 through the heat-conducting pipe.

[0168] Understandably, in the initial stage of ice making, a portion of the pipe connecting the second branch pipe 633 and the mold cavity 10 may freeze. Therefore, the portion of the pipe connecting the second branch pipe 633 and the mold cavity 10 is designed as a heat-conducting pipe. The heat-conducting pipe can be an aluminum pipe or a stainless steel pipe, and the heating element can be an electric heating wire.

[0169] Thus, when ice making ends, the heating element can be turned on, and the heat from the heating element is conducted to the heat pipe. The heat pipe heats up and causes the ice inside the heat pipe to melt, so that the prepared ice ball can be separated from the inner wall of the mold cavity 10.

[0170] In some embodiments, the inner diameter of the outlet end of the second branch pipe 633 is 3-5 mm, for example, the inner diameter of the outlet end of the second branch pipe 633 can be 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.

[0171] Understandably, the outlet end of the second branch pipe 633 is connected to the inlet 1011 of the mold cavity 10. By configuring the inner diameter of the outlet end of the second branch pipe 633, the melting of ice in a part of the pipe connected to the mold cavity 10 can be controlled by heating when the ice making ends. This design not only ensures the shape of the prepared ice ball, but also improves the efficiency of ice ball demolding.

[0172] In some embodiments, such as Figure 20As shown, in order to improve the efficiency of water supply to the mold cavity 10, multiple sets of second branch pipes 633 are provided, and the outlet ends of the multiple sets of second branch pipes 633 are respectively connected to the same mold cavity 10.

[0173] Two sets of the second branch pipe 633 are provided. The outlet ends of the two sets of the second branch pipe 633 are connected to the two inlets 1011 on the same mold cavity 10. The two inlets 1011 are centrally symmetrical about the axis of the outlet 1012 of the mold cavity 10. The water inlet direction of each inlet 1011 is inclined downward relative to the horizontal plane, and is set at an angle relative to the line connecting the inlet 1011 and the outlet 1012 on the horizontal projection plane.

[0174] In some embodiments, the second branch pipe 633 includes a plurality of water supply branch pipes 6331, the first ends of which are respectively connected to the main pipe 631, and the second ends of which are configured to be connected to a plurality of mold cavities 10 in a one-to-one correspondence. Each water supply branch pipe 6331 has the same length and inner diameter to ensure that the water flow rate supplied by each water supply branch pipe 6331 to the corresponding mold cavity 10 is approximately the same.

[0175] In some embodiments, such as Figure 4 and Figure 14 As shown, in order to facilitate the collection of water returning from the water collection tank 12, the water tank 61 is set with its opening facing upwards. The water collection tank 12 has a guide port 120, which is located on the upper side of the water tank 61 to guide the water in the water collection tank 12 to flow into the water tank 61.

[0176] In some embodiments, such as Figure 4 , Figure 16 and Figure 17 As shown, the temperature control component 7 includes: a heat insulation cover 71, a heating plate 72, and a fan 73; the heat insulation cover 71 is installed on the upper side of the water collection tank 12; the heating plate 72 is located between the heat insulation cover 71 and the water collection tank 12, thus creating a circulating air duct 701 between them; the fan 73 is located in the circulating air duct 701, and is used to drive the airflow along the circulating air duct 701 to achieve convective heat exchange between the airflow and the water in the water collection tank 12. Figure 4 Arrows are used to indicate the direction of airflow along the circulation duct 701.

[0177] Understandably, the heating plate 72 includes a heat-conducting plate and multiple electric heating wires disposed on the heat-conducting plate. The heat-conducting plate is horizontally arranged, and the electric heating wires are disposed on the upper surface of the heat-conducting plate. The upper surface of the heat-conducting plate faces the top of the insulation cover 71, and the lower surface of the heat-conducting plate faces the water collection tank 12. Gaps are left between the left end of the heat-conducting plate and the left side wall of the insulation cover 71, and between the right end of the heat-conducting plate and the right side wall of the insulation cover 71. In this way, the heating plate 72 can create a circulating air duct 701 between the insulation cover 71 and the water collection tank 12.

[0178] In practical applications, at least one fan 73 is provided, which is positioned between the left end of the heat-conducting plate and the left side wall of the insulation cover 71. When the fan 73 is started, the airflow flows along the gap between the upper surface of the heat-conducting plate and the top of the insulation cover 71, then flows through the gap between the right end of the heat-conducting plate and the right side wall of the insulation cover 71, and then flows through the gap between the lower surface of the heat-conducting plate and the water collection tank 12. During this process, the airflow flows over the surface of the water in the water collection tank 12 and exchanges heat with the water through convection. Then, the airflow after heat exchange flows through the gap between the left end of the heat-conducting plate and the left side wall of the insulation cover 71, thereby achieving circulation.

[0179] In some embodiments, such as Figure 4 and Figure 17 As shown, in order to facilitate precise control of the water temperature in the water collection tank 12, the temperature control component 7 also includes: a control module and a second temperature sensor 702; the second temperature sensor 702 is electrically connected to the control module, and the control module is electrically connected to the fan 73 and the heating plate 72 respectively; the second temperature sensor 702 is used to collect water temperature information flowing from the water collection tank 12 to the water supply component 6, and the control module is used to control the working status of the fan 73 and the heating plate 72 according to the water temperature information fed back by the second temperature sensor 702.

[0180] In practical applications, based on the water temperature information fed back by the second temperature sensor 702, the control module can control the wind speed and on / off state of the fan 73, as well as the heating power and on / off state of the heating plate 72, to ensure that the water temperature in the water collection tank 12 is maintained between 0℃ and 2℃. This ensures both the release of air bubbles in the water and the freezing speed of the water in the mold cavity 10, while also ensuring the return water temperature of the mold cavity 10, preventing the water inlet 1011 of the mold cavity 10 from freezing due to excessively low water temperature, thereby reliably producing transparent ice.

[0181] The control module can be a microcontroller or a PLC controller. When controlling the water temperature in the water collection tank 12, the temperature control range set by the control module is -2℃ to 2℃.

[0182] In some embodiments, such as Figure 22 , Figure 23 and Figure 24As shown, the lower mold assembly 2 includes: a lower mold shell 21, an evaporator 22, and a second heating element 23; the lower mold shell 21 is provided with a second mold cavity 102; the evaporator 22 is connected to the lower mold shell 21 to provide cooling for the freezing of water in the mold cavity 10; the second heating element 23 is disposed on the lower mold shell 21 and arranged around the second mold cavity 102.

[0183] Understandably, the lower mold shell 21 is configured to combine with the upper mold shell 11 to form a closed mold cavity 10 with the first mold cavity 101 of the upper mold shell 11 and the second mold cavity 102 of the lower mold shell 21.

[0184] Since the evaporator 22 is connected to the lower mold shell 21, and the water inlet 1011 and the water outlet 1012 are respectively located on the upper mold shell 11 and connected to the first mold cavity 101, during the ice-making process, based on the cooling capacity provided by the evaporator 22, the ice-making process in the mold cavity 10 is ensured to gradually freeze from bottom to top, thus ensuring the forming quality of the ice balls in the mold cavity 10.

[0185] In some embodiments, such as Figure 24 As shown, the lower mold shell 21 includes: a second fixing frame 211, a second elastic mold shell 212, and a heat-conducting component 213; the second elastic mold shell 212 is detachably disposed on the second fixing frame 211, and the second mold cavity 102 is constructed on the second elastic mold shell 212; the heat-conducting component 213 is disposed inside the second elastic mold shell 212, and at least part of the second elastic mold shell 212 and part of the heat-conducting component 213 enclose to form the second mold cavity 102; wherein, the heat-conducting component 213 is located at the bottom of the second mold cavity 102 and is connected to the evaporator 22.

[0186] Understandably, the heat-conducting component 213 is made of a metal material with a high thermal conductivity, such as a copper or aluminum component. The first elastic mold shell 112 of the upper mold shell 11 and the second elastic mold shell 212 of the lower mold shell 21 are both made of silicone.

[0187] Since the first elastic mold shell 112 and the second elastic mold shell 212 are assembled together, forming a closed mold cavity 10 between the first elastic mold shell 112 and the second elastic mold shell 212, considering that the thermal conductivity of the first elastic mold shell 112 and the second elastic mold shell 212 is lower than that of the thermal conductivity of the thermal conductive element 213, and the thermal conductive element 213 is located at the bottom of the mold cavity 10, the water in the mold cavity 10 freezes in an upward order. During the freezing process, the rate of bubble precipitation in the water in the mold cavity 10 is greater than the freezing rate of the water, thereby ensuring the transparency of the prepared ice ball.

[0188] In some embodiments, such as Figure 26 As shown, this embodiment of the invention also provides a refrigeration device, including: a device body 8 and an ice-making device as described above; the ice-making device is disposed on the device body 8. The refrigeration device can be a freezer or cold storage known in the art.

[0189] Since the refrigeration equipment includes an ice-making device, and the specific structure of the ice-making device is as described in the above embodiments, the refrigeration equipment in this embodiment includes all the technical solutions described above. Therefore, it has at least all the beneficial effects achieved by all the technical solutions described above, which will not be elaborated here.

[0190] In some embodiments, such as Figure 24 , Figure 25 and Figure 26 As shown, the main body of the equipment 8 has a refrigeration compartment 81 and a freezing compartment 82. The ice-making device is located in the refrigeration compartment 81. The refrigeration equipment also includes a guide air component 9. The freezing compartment 82 is connected to the ice-making device through the guide air component 9. The guide air component 9 is used to guide the cold air flow in the freezing compartment 82 to the ice-making mold so as to cause the water in the mold cavity 10 to freeze.

[0191] Specifically, for refrigeration equipment, the temperature inside the freezer compartment 82 is usually lower than the temperature inside the refrigerator compartment 81. For example, the temperature inside the refrigerator compartment 81 is 2℃~4℃, while the temperature inside the freezer compartment 82 is -18℃~-22℃.

[0192] The frame 4 of the ice-making device is installed in the cold storage room 81 and connected to the main body 8 of the device; the air guide 9 can be an insulating foam component, and the air guide 9 has a first air duct 91 and a second air duct 92. The first air duct 91 and the second air duct 92 are isolated from each other and extend along the extension direction of the air guide 9.

[0193] The lower mold shell 21 is provided with an air cavity and an air inlet and an air outlet connected to the air cavity. The evaporator 22 is located in the air cavity. The first end of the first air duct 91 and the first end of the second air duct 92 are both connected to the freezer compartment 82. The second end of the first air duct 91 and the second end of the second air duct 92 are respectively connected to the air inlet and the air outlet.

[0194] Thus, in practical applications, the cold airflow in the freezer compartment 82 enters the air cavity along the first air duct 91, and after exchanging heat with the evaporator 22, returns to the freezer compartment 82 along the second air duct 92. During this process, the evaporator 22 obtains cooling capacity based on the heat exchange with the cold airflow, and conducts the cooling capacity to the heat-conducting element 213 in the lower mold shell 21, so as to control the freezing of water in the mold cavity 10 by using the heat-conducting element 213.

[0195] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
