Description

Technical Field

[0002] With the diversification of life needs, users will choose to add ice cubes to drinks to improve the taste of the drinks, thus the demand for ice making is increasing.

[0003] In the prior art, ice is primarily made manually or automatically using ice molds. These molds typically consist of an upper mold assembly and a lower mold assembly that can be assembled together, forming a mold cavity for ice production. In actual use, it has been found that the existing upper mold assembly is simple in structure and poorly designed. Ice balls made using these upper molds contain bubbles and appear opaque. Consequently, when used to cool beverages (such as whiskey), the ice balls melt too quickly, affecting the taste of the beverage. Furthermore, the opacity of the ice balls also impacts the user experience. Utility Model Content

In the present application, the illustrative description of the above terms is not necessarily for the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0080] The following will be described in combination with Figures 1-26, the ice-making device and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0081] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the embodiment of the present invention provides an ice-making device, comprising: an ice-making mold, a water supply component 6 and a temperature control component 7;

[0082] The ice-making mold has a mold cavity 10 and a water inlet 1011 and a water outlet 1012 connected to the mold cavity 10. The water outlet 1012 is provided at the top of the mold cavity 10, and the water inlet 1011 is provided on one side of the water outlet 1012 and is inclined downward to supply water into the mold cavity 10.

[0083] 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 supply temperature of the water supply component 6 to the mold cavity 10.

[0084] It is understandable that the ice-making mold is configured to be connected to a cold source. Based on the cold amount provided by the cold source, the water in the mold cavity 10 condenses into ice cubes of a characteristic shape, and the appearance of the ice cubes is adapted to the shape of the mold cavity 10.

[0085] For example, the mold cavity 10 can be spherical, cylindrical, cubic, etc., without specific limitation. Since ice hockey pucks are widely used in actual consumption, the design scheme of the embodiment of the utility model will be specifically described below using an ice hockey puck made based on a spherical mold cavity 10 as an example.

[0086] By arranging 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, thereby ensuring the integrity and consistency of the shape of the ice ball.

[0087] 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 solution, this design can remove bubbles in the ice ball to a certain extent, making the ice ball appear transparent.

[0088] Furthermore, by arranging the water inlet 1011 on one side of the water outlet 1012 and supplying water obliquely downward toward the mold cavity 10, this design can utilize the disturbing effect of the incoming water flow to drive the water to flow in the mold cavity 10 during the ice making process, thereby promoting the precipitation of bubbles in the water and preventing the appearance of the formed ice balls from being affected by the inclusion of bubbles.

[0089] In this way, based on the design of the water inlet 1011 and the water outlet 1012 , a transparent ice ball that matches the shape of the mold cavity 10 can be prepared by the ice-making mold.

[0090] Considering that during the ice-making process, if the water temperature is too high, high-temperature water will enter the mold cavity 10, which will affect the freezing speed and even cause the ice to fail to form. If the water temperature is too low, the freezing speed will be too fast and the bubbles in the water will not be able to precipitate in time, resulting in the inability to prepare transparent ice. Therefore, the embodiment of the present invention adopts a temperature control component 7 to regulate the water temperature in the water system.

[0091] Since the temperature control component 7 is configured to adjust the temperature of the water supplied by the water supply component 6 to the mold cavity 10 , this design not only promotes the precipitation of bubbles in the water, but also ensures the freezing speed in the mold cavity 10 .

[0092] Illustratively, during the ice making process, the temperature control component 7 controls the water supply temperature of 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 refrigeration plate.

[0093] As can be seen from the above, by providing the ice-making device with an ice-making mold, a water supply component 6 and a temperature control component 7, during the ice-making process, the water supply component 6 and the mold cavity 10 form a circulating water system, which ensures that the mold cavity 10 is filled with water while ensuring that the mold cavity 10 is in a dynamic flow state. In addition, the water temperature in the mold cavity 10 is regulated based on the temperature control component 7, which not only promotes the precipitation of bubbles in the water, but also ensures the freezing speed in the mold cavity 10. This design can produce transparent ice based on the ice-making mold and ensure the ice-making efficiency.

[0094] Of course, in some application scenarios, compared with the static ice-making solution, as long as the transparency and integrity of the prepared ice balls are improved to a certain extent, the ice-making device can also be configured to include the above-mentioned ice-making mold and water supply component 6. The water supply component 6 is configured to supply water to the mold cavity 10 of the ice-making mold, and it is also not necessary to set the water supply component 6 and the mold cavity 10 as a circulating water system.

[0095] In some embodiments, 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 driving assembly 3;

[0096] The upper mold assembly 1 is provided with a first mold cavity 101 and a water inlet 1011 and a water outlet 1012 communicated with the first mold cavity 101; the lower mold assembly 2 is provided with a second mold cavity 102, and 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;

[0097] 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.

[0098] It can be understood that the first mold cavity 101 and the second mold cavity 102 are both open, the first mold cavity 101 is formed on the lower surface of the upper mold assembly 1, and the second mold cavity 102 is formed on the upper surface of the lower mold assembly 2; wherein, when the mold cavity 10 is a spherical cavity, the first mold cavity 101 and the second mold cavity 102 are both hemispherical.

[0099] In actual application, the upper mold assembly 1 and the drive assembly 3 are respectively arranged on the frame 4, and 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.

[0100] like Figure 1 As shown, when the lower mold assembly 2 is in the first state, the lower mold assembly 2 is located on the lower side of 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.

[0101] 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 driving of the driving assembly 3, so that the upper mold assembly 1 and the lower mold assembly 2 are separated.

[0102] For example, 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 arranged on the frame 4, and the transmission shaft 32 is rotatably arranged on the frame 4. The drive motor 31 is connected to the transmission shaft 32, and the transmission shaft 32 is connected to the first end of the transmission arm 33. The second end of the transmission arm 33 is connected to the lower mold assembly 2.

[0103] At the same time, the lower mold assembly 2 is rotatably provided on the frame 4 through a hinge shaft. When the drive motor 31 is started, the drive motor 31 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the transmission arm 33 to swing, and then the transmission arm 33 drives the lower mold assembly 2 to flip 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.

[0104] Further, if Figure 2 and Figure 24As shown, a floating frame 24 is provided at the bottom of the lower mold assembly 2. The floating frame 24 includes an elastic member 241 and a frame body 242. The elastic member 241 is disposed 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. Thus, when the drive assembly 3 drives the lower mold assembly 2 to switch from the second state to the first state, the elastic force of the elastic member 241 ensures that the lower mold assembly 2 contacts the upper mold assembly 1, thereby forming a single assembly. This design not only prevents damage to the upper and lower mold assemblies 1, 2 from colliding with each other, but also ensures a seal between the upper and lower mold assemblies 1, 2 during the ice-making process.

[0105] In some embodiments, as Figure 4 、 Figure 5 and Figure 8 As shown, an embodiment of the present invention provides an ice-making device, comprising: a frame 4, a flow guide 5 and the above ice-making mold;

[0106] The flow guide 5 is configured to be disposed on one side of the ice-making mold and movably disposed on the water supply assembly 6, which is used to supply water to the ice-making mold;

[0107] 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 arranged on a frame 4. A sealing structure is provided between the opposing 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.

[0108] When the lower mold assembly 2 is in the first state, the upper mold assembly 1 is sealed with the lower mold assembly 2 through the sealing structure, and the lower mold assembly 2 and the flow guide 5 are in contact, so that the overflow port and the flow guide 5 are arranged opposite to each other in the upper and lower directions; 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 flow guide 5 are separated;

[0109] In the event of a failure of the sealing structure, the water in the ice making mold can pass through the sealing structure and flow to the overflow port, then flow from the overflow port to the guide member 5, and then flow to the water supply assembly 6 under the guidance of the guide member 5. Figure 5 The letter X is used to identify 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.

[0110] It is understandable that the sealing structure may be an elastic sealing ring or the like, and the sealing structure is configured to extend along the circumference of the mold cavity 10 of the ice-making mold to prevent water in the mold cavity 10 from leaking.

[0111] 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 clamped between the lower surface of the upper mold assembly 1 and the upper surface of the lower mold assembly 2 to achieve waterproof sealing of the mold cavity 10 along the circumferential direction.

[0112] At the same time, an overflow port is provided at one end of the ice-making mold close to the water supply assembly 6; only when the lower mold assembly 2 is in the first state, the upper mold assembly 1 and the lower mold assembly 2 are assembled as one, and an overflow port is formed between the upper mold assembly 1 and the lower mold assembly 2; in actual work, if the sealing structure has not failed, the mold cavity 10 will not leak under the sealing action 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 assembly 1 and the lower mold assembly 2, and pass through the sealing structure during the flow, and then flow to the overflow port, and then flow to the guide member 5 through the overflow port, and then flow to the water supply assembly 6 under the guidance of the guide member 5. This design realizes the recovery of water overflowing from the mold cavity 10, and prevents water from flowing to other places except the ice-making mold.

[0113] During the process of switching the lower mold assembly 2 from the second state to the first state, the lower mold assembly 2 flips toward the side close to the upper mold assembly 1. During the flipping process, the lower mold assembly 2 will contact the guide member 5 and drive the guide member 5 to move. When the upper mold assembly 1 and the lower mold assembly 2 are assembled, the guide member 5 is just on the lower side of the overflow port.

[0114] 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 toward the side away from the upper mold assembly 1, and the lower mold assembly 2 will separate from the guide member 5 during the flipping process. 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 overflow port between the upper mold assembly 1 and the lower mold assembly 2, and the guide member 5 will not play a role in drainage.

[0115] like Figure 1 and Figure 4 As shown, the water supply component 6 is arranged on the frame 4, and the water supply component 6 includes a water tank 61, a water pump 62 and a water supply pipe 63; the water pump 62 is connected to the water supply pipe 63, and the water supply pipe 63 is arranged between the water tank 61 and the mold cavity 10, and the water pump 62 is used to deliver the water in the water tank 61 to the mold cavity 10.

[0116] like Figure 5As shown, the flow guide 5 is configured to be movably arranged on the water tank 61; during the switching process of the lower mold assembly 2 from the second state to the first state, the flow guide 5 can be configured to be translated in the vertical plane relative to the water tank 61 under the driving of the lower mold assembly 2, or can be configured to be translated in the horizontal plane relative to the water tank 61 under the driving of the lower mold assembly 2, and no specific limitation is made, as long as the overflow port and the flow guide 5 are arranged in an upper-lower relative manner when the upper mold assembly 1 and the lower mold assembly 2 are assembled, and the water overflowing from the overflow port can be guided by the flow guide 5.

[0117] As can be seen from the above, the ice-making device shown in the embodiment of the utility model, through setting flow guide 5 on one side of ice-making mold, and movably setting flow guide 5 on water supply assembly 6, during the process that ice-making mold is closed to upper mold assembly 1 under the control of driving assembly 3 lower mold assembly 2, can drive flow guide 5 to move relative to water supply assembly 6 by lower mold assembly 2, until flow guide 5 reaches the lower side of overflow port, so that when the sealing structure fails, flow guide 5 can guide the water flow overflowing from overflow port to water supply assembly 6, realizing the recycling of water flow overflowing from overflow port, preventing water flow from going to other places except ice-making mold.

[0118] In some embodiments, as shown in Figure 4 and Figure 10 As shown, the flow guide 5 is movably arranged on the water tank 61 along the first direction, and the first direction is arranged obliquely relative to the horizontal plane; in the case that the lower mold assembly 2 is in the first state, the flow guide 5 is located at a position close to the lower mold assembly 2 and at the first height; in the case that the lower mold assembly 2 is in the second state, the flow guide 5 can fall to a position away from the lower mold assembly 2 and at the second height under the action of its own gravity; wherein the first height is greater than the second height.

[0119] It can be understood that the first direction is a direction obliquely relative to the horizontal plane, and the angle of the first direction relative to the horizontal plane can be 30º-60º. The flow guide 5 is movably arranged on the water tank 61 along the first direction.

[0120] During the process that the lower mold assembly 2 is flipped from the second state to the first state, the lower mold assembly 2 drives the flow guide 5 to move obliquely upward relative to the water tank 61, and gradually approaches the overflow port in the horizontal direction, and when the upper mold assembly 1 and the lower mold assembly 2 are assembled, the flow guide 5 stops at a position at the first height and is just located at the lower side of the overflow port.

[0121] Correspondingly, during the process of flipping the lower mold assembly 2 from the first state to the second state, the lower mold assembly 2 separates from the guide member 5 during the flipping process, and the guide member 5 can move downwardly relative to the water tank 61 under the action of its own gravity, and gradually move away from the overflow port in the horizontal direction until the guide member 5 stops at a position at the second height. At this time, the position of the guide member 5 is away from the flipping path of the lower mold assembly 2, so that it will not affect the flipping movement of the lower mold assembly 2.

[0122] In some embodiments, 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 a portion of the guide member 5 is arranged to extend downwardly and obliquely toward the side away from the ice-making mold.

[0123] For example, when the lower mold assembly 2 is in the first state, the portion of the flow guide 5 that overlaps with the overflow port in the vertical direction can be arranged to extend obliquely downward toward the side away from the ice-making mold.

[0124] In some embodiments, as Figure 8 and Figure 9 As shown, the lower mold assembly 2 has a first inclined surface P1, and the flow guide member 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 to drive the flow guide member 5 to move along the first direction relative to the water supply assembly 6.

[0125] It is understandable that since the lower mold assembly 2 and the guide member 5 are slidably fitted through the first inclined surface P1 and the second inclined surface P2, the lower mold assembly 2 can apply a force with horizontal and vertical components to the guide member 5 through the first inclined surface. This force setting not only meets the requirement of the flipping movement of the lower mold assembly 2 relative to the upper mold assembly 1, but also ensures that the guide member 5 can be driven by the lower mold assembly 2 to move along the first direction relative to the water tank 61.

[0126] In some embodiments, as Figure 9 、 Figure 10 and Figure 11 As shown, the guide member 5 includes: a guide plate 51 and an ear seat 52; the guide plate 51 extends downwardly and obliquely toward the side away from the ice-making mold; the ear seat 52 is connected to the guide plate 51 and slides 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, and the support 2002 is provided with a first inclined surface P1, and the support 2002 and the ear seat 52 can slide with each other through the first inclined surface P1 and the second inclined surface P2.

[0127] Specifically, the ear seat 52 is provided with an inner cavity, which is open and downwardly disposed, and the second inclined surface is formed on the inner wall surface of the inner cavity on a side close to the ice-making mold.

[0128] In actual application, at least part of the support 2002 extends into the inner cavity, and the support 2002 uses its first inclined surface to slide with the second inclined surface in the ear seat 52. This design achieves a compact fit between the guide member 5 and the lower mold assembly 2, reducing space occupancy.

[0129] In some embodiments, 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 is extended along the first direction, and the sliding shaft 53 is movably inserted into the strip hole 610 .

[0130] Specifically, the strip 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 hole 610. This design can ensure that the sliding shaft 53 can only move relative to the strip hole 610 along the extension direction of the strip hole 610, and cannot rotate in the strip hole 610.

[0131] In some embodiments, as Figure 10 and Figure 11 As shown, in order to ensure the stability of the movement of the guide member 5 relative to the water tank 61, two ear seats 52 are provided, and the two ear seats 52 are spaced apart from each other and arranged side by side; the guide plate 51 is provided between the two ear seats 52; and two supports 2002 are provided, and the two supports 2002 are spaced apart from each other and are respectively arranged opposite to the two ear seats 52.

[0132] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the embodiment of the present invention further provides an ice-making mold, comprising: an upper mold assembly 1 and a lower mold assembly 2;

[0133] The lower surface of the upper mold assembly 1 is provided with a boss structure 1001, and the boss structure 1001 has a first mold cavity 101 on its surface. 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 has a second mold cavity 102. The groove of the groove structure 2001 is provided with a guide portion extending toward the outside of the groove structure 2001.

[0134] The upper mold assembly 1 and the lower mold assembly 2 are arranged in an upper and lower relative manner. 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 in the mold cavity 10 from flowing out.

[0135] In the event of a failure of the sealing structure, the water in the mold cavity 10 can pass through the sealing structure and flow to the guide portion, and then flow through the guide portion to the water supply assembly 6 for supplying water to the mold cavity 10. Figure 5 The letter D is used to identify 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.

[0136] It can be understood that, for the upper mold assembly 1, the boss structure 1001 is constructed on the lower surface of the upper mold assembly 1, and is convexly arranged 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 concavely arranged along the vertical direction toward the inside of the lower mold assembly 2.

[0137] At the same time, 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 in correspondence, the table surface of the boss structure 1001 and the groove bottom surface of the groove structure 2001 correspond to each other and fit together, and the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001 correspond to each other and fit together, so that the first mold cavity 101 and the second mold cavity 102 form a closed mold cavity 10. Among them, sealing structures can be provided between the table surface of the boss structure 1001 and the groove bottom surface of the groove structure 2001, as well as between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001. The sealing structures can be made of elastic sealing rings.

[0138] 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 composed 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 better 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 along an inclined upward path, and the overflowing water will also return to the water supply assembly 6 through the guide part to prevent the water from flowing to other places except the ice-making mold. Therefore, this design not only ensures the reliable sealing performance of the ice-making mold, but also can provide better overflow protection for water overflowing from the mold cavity 10 when the seal fails.

[0139] In some embodiments, as Figure 5 and Figure 6 As shown, the sealing structure includes: a first sealing component 201 , which is arranged between the table surface of the boss structure 1001 and the groove bottom surface of the groove structure 2001 , and extends along the circumference of the mold cavity 10 .

[0140] It can be understood that the first sealing assembly 201 can be configured in a ring shape, for example, the first sealing assembly 201 is an elastic sealing ring. As the first sealing of the mold cavity 10, the first sealing assembly 201 can effectively prevent the water in the mold cavity 10 from leaking by using the sealing performance of the first sealing assembly 201.

[0141] In some embodiments, as shown in Figure 6 , the first sealing assembly 201 includes a protrusion and a groove; the protrusion and the groove are respectively arranged along the circumference of the mold cavity 10; one of the protrusion and the groove is arranged on the mesa of the boss structure 1001, and the other of the protrusion and the groove is arranged on the groove bottom surface of the groove structure 2001.

[0142] In the case where the boss structure 1001 is embedded in the groove structure 2001, the mesa of the boss structure 1001 and the groove bottom surface of the groove structure 2001 are fitted, and the protrusion is embedded in the groove.

[0143] It can be understood that based on the nested fit between the protrusion and the groove, the sealing connection between the mesa of the boss structure 1001 and the groove bottom surface of the groove structure 2001 is realized while ensuring that the mesa of the boss structure 1001 and the groove bottom surface of the groove structure 2001 are fitted, which is beneficial to tightly combining the first mold cavity 101 and the second mold cavity 102 into one to form a complete mold cavity 10, thereby ensuring the forming quality of the ball ice.

[0144] Further, the part of the upper mold assembly 1 corresponding to the boss structure 1001 and the part of the lower mold assembly 2 corresponding to the groove structure 2001 can 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 and the inner wall of the groove abut, which further ensures the sealing effect of the first sealing assembly 201.

[0145] In some embodiments, as shown in Figure 6 , in order to ensure the sealing effect of the mold cavity 10, the first sealing assembly 201 is provided with multiple sets, and the multiple sets of first sealing assemblies 201 are arranged from inside to outside with respect to the mold cavity 10. Each set is arranged along the circumference of the mold cavity 10 and is composed of a protrusion and a groove that can be embedded together.

[0146] In some embodiments, as shown in Figure 4 , Figure 5 , and Figure 6 , a plurality of mold cavities 10 are formed between the upper mold assembly 1 and the lower mold assembly 2 and are spaced apart from each other. The first sealing assembly 201 is provided with multiple sets, and the multiple sets of first sealing assemblies 201 are respectively arranged one-to-one corresponding to the plurality of mold cavities 10 to seal each mold cavity 10.

[0147] In some embodiments, as shown in Figure 5 , andFigure 7 As shown, the sealing structure includes: a second sealing component 202; the second sealing component 202 is arranged between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001, and extends along the circumference of the boss structure 1001.

[0148] It is understandable that the second sealing component 202 can also be configured in an annular shape, for example, the second sealing component 202 is an elastic sealing ring. The second sealing component 202 is used to achieve sealing between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001.

[0149] The second sealing component 202 serves as a second seal to protect the mold cavity 10 from leakage. When multiple mold cavities 10 are provided between the table surface of the boss structure 1001 and the bottom surface of the groove 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 above-mentioned first sealing component 201 fails, the second sealing component 202 prevents water overflowing from the mold cavity 10 from continuing to flow along the gap between the peripheral wall of the boss structure 1001 and the groove wall surface of the groove structure 2001 toward the outside of the ice-making mold.

[0150] In some embodiments, as Figure 5 and Figure 7 As shown, the second sealing assembly 202 includes: an elastic sealing strip; the elastic sealing strip is provided on the peripheral wall of the boss structure 1001 and extends along the circumference of the boss structure 1001; the elastic sealing strip is also provided at an angle to the peripheral wall of the boss structure 1001 and extends upwardly and obliquely toward the side away from the table surface;

[0151] When the boss structure 1001 is embedded in the groove structure 2001 , a side surface of the elastic sealing strip facing away from the boss structure 1001 abuts against a groove wall surface of the groove structure 2001 .

[0152] It is understandable that, since the portion 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 integrated structure.

[0153] Since 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 in the direction perpendicular to the peripheral wall of the boss structure 1001, when the upper mold assembly 1 and the lower mold assembly 2 are assembled up and down, the elastic sealing strip will deform and abut against the groove wall of the groove structure 2001, thereby better blocking the path of water flowing 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 to additionally set up the second sealing assembly 202 during the assembly of the ice-making mold, and its operation is simple and convenient.

[0154] In actual application, in order to ensure the water-blocking sealing effect of the second seal, multiple elastic sealing strips can be set, and the multiple elastic sealing strips are respectively set on the peripheral wall of the boss structure 1001, and are arranged in sequence along the water overflow path from the mold cavity 10 to the outside of the ice-making mold.

[0155] In some embodiments, as Figure 12 、 Figure 13 、 Figure 15 and Figure 21 As shown, an embodiment of the present invention provides an upper mold assembly 1, comprising: a water collecting trough 12, an upper mold shell 11 and an adapter 13;

[0156] A water outlet hole 122 is provided at the bottom of the water collecting trough 12; the upper mold shell 11 is provided on the lower side of the water collecting trough 12, and a first mold cavity 101 is provided on the side of the upper mold shell 11 facing away from the water collecting trough 12, and a water outlet 1012 and a sealing portion 1120 extending circumferentially along the water outlet 1012 are provided on the side of the upper mold shell 11 facing the water collecting trough 12. The first mold cavity 101 is connected to the water outlet hole 122 through the water outlet 1012, and the sealing portion 1120 is sealed and connected to the bottom of the water collecting trough 12; the adapter 13 is connected to the water collecting trough 12, and the sealing portion 1120 is clamped between the bottom of the water collecting trough 12 and the adapter 13.

[0157] It is understandable that the sealing portion 1120 can be configured as a circle, the water outlet 1012 is located at the center of the sealing portion 1120, and is configured to be coaxially connected to the water outlet 122 on the water collecting tank 12 to achieve communication between the first mold cavity 101 and the water outlet 122 through the water outlet 1012.

[0158] A sealant or other sealing structure may be provided between the upper surface of the sealing portion 1120 and the bottom surface of the bottom of the water collecting trough 12 to achieve a sealed connection between the sealing portion 1120 and the bottom of the water collecting trough 12. Furthermore, the first mold cavity 101 may be provided with a water inlet 1011 communicating with the first mold cavity 101, and a water outlet 1012 is provided at the top of the first mold cavity 101 and communicates with the water outlet hole 122 at the bottom of the water collecting trough 12.

[0159] In addition, the adapter 13 can be made of a material with a harder hardness than the sealing portion 1120 , and the adapter 13 is connected to the bottom of the water collecting tank 12 through locking members such as screws and bolts.

[0160] As can be seen from the above, the upper mold assembly 1 shown in the embodiment of the present invention, by providing a sealing portion 1120 extending along the circumference of the water outlet 1012 of the upper mold shell 11, can achieve a waterproof seal of the water outlet 1012 based on the sealed connection between the sealing portion 1120 and the bottom of the water collecting tank 12 when the water outlet 1012 is connected to the water outlet hole 122 of the water collecting tank 12, and achieve the connection between the water collecting tank 12 and the upper mold shell 11 by connecting the adapter 13 to the water collecting tank 12 and clamping the sealing portion 1120 between the bottom of the water collecting tank 12 and the adapter 13. This design not only completes the assembly of the water collecting tank 12 and the upper mold shell 11, but also ensures a waterproof seal between the water collecting tank 12 and the upper mold shell 11, and ensures that the water in the first mold cavity 101 can overflow into the water collecting tank 12, and will not flow into the gap between the water collecting tank 12 and the upper mold shell 11.

[0161] In some embodiments, as Figure 15 As shown, the adapter 13 includes: a base 131 and an adapter column 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 portion 1120 is clamped between the bottom of the water collecting tank 12 and the base 131; the adapter column 132 is connected to the base 131, and is provided on the side of the base 131 facing the water collecting tank 12, and the adapter column 132 is connected to the bottom of the water collecting tank 12.

[0162] In order to facilitate the clamping of the sealing part 1120, a positioning groove is provided on the side of the base 131 facing the water collecting tank 12, and at least part of the sealing part 1120 is embedded in the positioning groove, and the sealing part 1120 is clamped between the bottom of the water collecting tank 12 and the bottom of the positioning groove.

[0163] In some embodiments, as Figure 13 and Figure 21 As shown, the water collection tank 12 includes: a fixed column 121; the fixed column 121 is arranged in the water collection tank 12, the fixed column 121 has a plug-in cavity and a through-hole connected to the plug-in cavity, the plug-in cavity is open on the side facing the bottom of the tank, and the through-hole is provided at the top of the fixed column 121; the adapter column 132 is inserted in the plug-in cavity; the fixed column 121 is connected to the adapter column 132 through a locking piece passed through the through-hole.

[0164] In actual application, the base 131 of the adapter 13 is first sleeved on the peripheral wall of the water outlet 1012, and then the water collection tank 12 is placed on the upper side of the upper mold shell 11, and the adapter column 132 of the adapter 13 is inserted into the plug-in cavity of the fixed column 121, and then the locking piece is passed through the through hole of the fixed column 121, and the locking piece is connected to the adapter column 132 to realize the assembly of the water collection tank 12, the upper mold shell 11 and the adapter 13 into one, and the operation is simple and convenient.

[0165] The locking member may be a locking screw, and the adapter 13 is provided with a locking screw hole. The screw rod of the locking screw is threadedly matched with the locking screw hole, so that the fixing column 121 and the adapter column 132 are connected as one by the locking screw.

[0166] In some embodiments, as Figure 12 and Figure 15 As shown, in order to ensure the reliability of fixing the sealing part 1120, a plurality of adapter columns 132 are provided on the base 131, and the plurality of adapter columns 132 are arranged around the through hole; the water collecting tank 12 is provided with a plurality of fixing columns 121 arranged around the water outlet 122, and the plurality of adapter columns 132 are connected one-to-one with the plurality of fixing columns 121.

[0167] In some embodiments, as Figure 13 As shown, the height of the fixing column 121 is greater than the height of the rim of the water collecting tank 12 . This design can prevent the water in the water collecting tank 12 from overflowing into the fixing column 121 .

[0168] In some embodiments, as Figure 13 As shown, in order to ensure the sealing effect between the sealing portion 1120 and the bottom of the water collecting tank 12, the side of the sealing portion 1120 facing the water collecting tank 12 is in contact with the bottom surface of the water collecting tank 12, and a sealing structure 1101 is provided between the sealing portion 1120 and the opposite wall surface of the water collecting tank 12;

[0169] The sealing structure 1101 includes a sealing groove and a sealing rib, which is embedded in the sealing groove. Both the sealing groove and the sealing rib are extended along the circumference of the water outlet 1012; wherein, one of the sealing groove and the sealing rib is arranged at the bottom of the groove, and the other of the sealing groove and the sealing rib is arranged at the sealing part 1120.

[0170] In some embodiments, 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 provided on the upper mold shell 11 and is arranged around the first mold cavity 101.

[0171] It can be understood that the first heating member 14 is arranged outside the first mold cavity 101 and surrounds the first mold cavity 101. When the ice ball is demolded, the first heating member 14 can be used to heat the upper mold shell 11, so as to ensure that the peripheral wall of the ice ball is separated from the inner wall surface of the first mold cavity 101, and the ice ball and the upper mold shell 11 are separated.

[0172] Optionally, the first heating member 14 can be an electric heating wire.

[0173] Optionally, two sets of first heating members 14 can be provided, and the two sets of first heating members 14 are arranged in an upper and lower distribution. The first heating member 14 arranged on the upper side surrounds the water outlet 1012, and the first heating member 14 arranged on the upper side surrounds the peripheral wall of the first mold cavity 101.

[0174] In some embodiments, as shown in Figure 13 and Figure 14 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 arranged on the first fixed frame 111. The first mold cavity 101, the water inlet 1011 and the water outlet 1012 are respectively arranged on the first elastic mold shell 112.

[0175] The first mold cavity 101 can form a closed mold cavity 10 with the second mold cavity 102 in the lower mold assembly 2. At least part of the bottom wall of the second mold cavity 102 is configured to be connected with a cold source.

[0176] It can be understood that by configuring the first elastic mold shell 112 on the upper mold shell 11, the first elastic mold shell 112 can be in contact with the lower mold assembly 2, so as to ensure the sealing effect between the upper mold assembly 1 and the lower mold assembly 2.

[0177] At the same time, since the first elastic mold shell 112 is usually made of plastic materials such as silica gel, the heat conduction performance of the first elastic mold shell 112 is relatively poor. By configuring at least part of the bottom wall of the second mold cavity 102 to be connected with a cold source, the ice formation process in the mold cavity 10 can be ensured to be from bottom to top in the process of ice making. This design can ensure that the bubble precipitation speed of water in the mold cavity 10 is greater than the ice formation speed of water, so as to ensure the transparency of the prepared ice ball.

[0178] In some embodiments, the sealing part 1120 and the first elastic mold shell 112 are one-piece elastic members.

[0179] It can be understood that the sealing part 1120 and the first elastic mold shell 112 can be one-piece silica gel members.

[0180] Since the sealing portion 1120 is elastic, the sealing portion 1120 can be configured to be clamped between the bottom of the water collecting trough 12 and the adapter 13 in an interference fit manner. This design is conducive to ensuring the sealing effect of the sealing portion 1120 on the water outlet 1012.

[0181] In some embodiments, as Figure 12 、 Figure 13 and Figure 14 As shown, the embodiment of the present invention further provides an upper mold assembly 1, comprising: a water collecting trough 12 and the upper mold shell 11 as described above;

[0182] The water collecting tank 12 is configured to be able to transmit the water collected therein to the water supply assembly 6;

[0183] The upper mold shell 11 is disposed 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 connected to the first mold cavity 101; the first mold cavity 101 is open toward the lower side of the upper mold shell 11; the water inlet 1011 is configured to communicate with the water supply assembly 6; the water outlet 1012 is disposed at the top of the first mold cavity 101 and is connected to the water collection tank 12;

[0184] The water inlet 1011 is provided on one side of the water outlet 1012 , and the water inlet direction of the water inlet 1011 is inclined and extends downward relative to the horizontal plane.

[0185] It is understandable that the upper mold assembly 1 and the lower mold assembly 2 are used in conjunction with each other. 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.

[0186] like Figure 13 As shown, by arranging 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, thereby ensuring the integrity and consistency of the shape of the ice ball.

[0187] like Figure 13 As shown, the water inlet 1011 is positioned on one side of the water outlet 1012 and is tilted downwardly to feed water into the mold cavity 10. For example, the angle α of the water inlet direction of the water inlet 1011 relative to the vertical plane is α, and the range of α is 30° to 75°. The angle of inlet direction of the water inlet 1011 relative to the horizontal plane is 90°-α. This design ensures that the incoming water flows toward the bottom wall of the mold cavity 10 during the ice-making process. The disturbance of the incoming water flow drives the water to flow up and down in the mold cavity 10, thereby promoting the precipitation of bubbles in the water and preventing the appearance of the formed ice balls from being affected by the inclusion of bubbles.

[0188] In this way, based on the design of the water inlet 1011 and the water outlet 1012 , a transparent ice ball that matches the shape of the mold cavity 10 can be prepared by the ice-making mold.

[0189] Since the water supply component 6 is connected to the water inlet 1011 of the first mold cavity 101, the water outlet 1012 of the first mold cavity 101 is connected to the water collecting tank 12, and the water collecting 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 collecting 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 solution, the embodiment of the present utility model can remove bubbles in the ice ball to a certain extent, making the ice ball appear transparent.

[0190] As can be seen from the above, the upper mold assembly 1 shown in the embodiment of the present invention optimizes the configuration of the water inlet direction of the water inlet 1011 corresponding to the first mold cavity 101 and the position of the water outlet 1012 by setting a water collecting tank 12 on the upper side of the upper mold shell 11. During the ice-making process, a circulating water path can be formed based on the water supply assembly 6, the first mold cavity 101 and the water collecting tank 12 to ensure the circulation of water in the mold cavity 10 formed by the upper mold assembly and the lower mold assembly, and the disturbance of the incoming water flow can be utilized to ensure that the mold cavity 10 is filled with dynamically flowing water. Therefore, during the ice-making process, this design can make the bubbles in the water in the mold cavity 10 continuously precipitate, ensuring the integrity and consistency of the shape of the ice formed in the mold cavity, and can prepare transparent ice that matches the shape of the mold cavity 10.

[0191] In some embodiments, on a horizontal projection plane, the water inlet direction of the water inlet 1011 is arranged at an angle relative to the direction of a line connecting the water inlet 1011 and the water outlet 1012 .

[0192] It is understandable that while the water inlet direction of the water inlet 1011 is set to extend downwardly with respect to the horizontal plane, the water inlet direction of the water inlet 1011 is also set to be inclined with respect to the direction of the line between the water inlet 1011 and the water outlet 1012. This design can utilize the disturbing effect of the incoming water flow to drive the water to rotate in the mold cavity 10 to accelerate the precipitation of bubbles in the water.

[0193] In some embodiments, in order to improve the water inlet efficiency and accelerate the precipitation of bubbles in the water 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, the water inlet directions of at least some of the multiple water inlets 1011 have different angles relative to the direction of the line between the water inlet 1011 and the water outlet 1012.

[0194] Specifically, the angles of the water inlet directions of each water inlet 1011 relative to the line direction between the water inlet 1011 and the water outlet 1012 can be configured to be different, but each water inlet 1011 is used to drive water to rotate along the same rotation direction in the mold cavity 10.

[0195] Since multiple water inlets 1011 simultaneously supply water to the mold cavity 10, by setting the water inlet direction of each water inlet 1011, the water flows formed by different water 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 precipitation efficiency of bubbles in the water in the mold cavity 10.

[0196] In some embodiments, in order to ensure that water rotates stably in the mold cavity 10 , the water outlet 1012 is extended in the vertical direction, and the multiple water inlets 1011 are centrally symmetrically distributed relative to the axis where the water outlet 1012 is located.

[0197] For example, Figure 14 As shown, there are two water inlets 1011, which are located on both sides of the water outlet 1012, and the two water inlets 1011 are centrally symmetrically distributed with respect to the axis where the water outlet 1012 is located. The water inlet direction of each water inlet 1011 extends downwardly at an angle relative to the horizontal plane, and is also set at an angle relative to the direction of the line connecting the water inlet 1011 and the water outlet 1012 on the horizontal projection plane.

[0198] In some embodiments, as Figure 14 and Figure 21 As shown, the water collection tank 12 has a diversion port 120 , which is used to divert water in the water collection tank 12 to the water supply assembly 6 .

[0199] Specifically, the diversion port 120 is constructed on the groove wall of the water collection groove 12 at one end facing the water supply component 6. Under the drainage effect of the diversion port 120, the water in the water collection groove 12 will be transported to the water supply component 6 instead of flowing to other places.

[0200] The water supply component 6 supplies water to the mold cavity 10 through the water inlet 1011. After the water in the mold cavity 10 overflows from the water outlet 1012 into the water collecting tank 12, the water in the water collecting tank 12 returns to the water supply component 6 through the diversion port 120, realizing the circulation of water.

[0201] In some embodiments, as Figure 14 and Figure 21 As shown, in order to facilitate the drainage of water in the water collection tank 12 to the water supply assembly 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 downwardly toward the water supply assembly 6.

[0202] 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 configured to collect temperature information within the first mold cavity 101 . The temperature information fed back by the first temperature sensor 1102 facilitates real-time monitoring of the icing conditions within the mold cavity 101 .

[0203] In some embodiments, as Figure 4 、 Figure 18 and Figure 19 As shown, the embodiment of the present invention further provides a water system, including: a water tank 61, a water collection tank 12, a water pump 62 and a water supply pipeline 63;

[0204] The water collecting tank 12 is configured to be disposed on the upper side of the ice-making mold and communicate with the mold cavity 10 in the ice-making mold; the water collected in the water collecting tank 12 is configured to flow into the water tank 61;

[0205] The water pump 62 is connected to a water supply pipeline 63 . The water supply pipeline 63 is provided 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 .

[0206] It can be understood that the water system is composed 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 set at a height higher than the water tank 61, and the water pump 62 is located at the bottom of the water tank 61.

[0207] Optionally, the water inlet end of the water pump 62 is connected to the water tank 61, the water outlet end 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 water inlet 1011 of the mold cavity 10, and the water outlet 1012 of the mold cavity 10 is connected to the water collecting tank 12.

[0208] The water tank 61 can be configured to be connected to the frame 4 of the ice-making device, and the water tank 61 is configured to be covered in the heat-insulating cover 71 to ensure that the temperature in the water tank 61 is maintained between 0°C and 2°C. This design ensures the precipitation of bubbles in the water without affecting the freezing speed of the water in the mold cavity 10.

[0209] The water system shown in the embodiment of the present invention configures the ice-making mold with a water tank 61, a water collecting tank 12, a water pump 62 and a water supply pipe 63. Under the pumping of the water pump 62, the water in the water tank 61 will reach the water inlet 1011 along the water supply pipe 63, and then enter the mold cavity 10 through the water inlet 1011. After the water in the mold cavity 10 overflows from the water outlet 1012 to the water collecting tank 12, the water in the water collecting 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 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.

[0210] In some embodiments, 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 arranged 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.

[0211] It is understandable that during the ice-making process, as the water in the mold cavity 10 continues to freeze, the second branch pipe 633 near the end of the mold cavity 10 will also freeze. In order to avoid freezing during the operation of the water pump 62, the main pipe 631 is connected to the water tank 61 through the first branch pipe 632.

[0212] At the same time, a first control valve can be set on the first branch pipeline 632, and a second control valve can be set on the second branch pipeline 633. The first control valve and the second control valve can be used to control the conduction state of the water supply pipeline 63.

[0213] During the initial ice-making phase, water in the water tank 61 is pumped by the water pump 62 into the mold cavity 10 along the main pipe 631 and the second branch pipe 633, and then returns to the water tank 61 through the water collection tank 12. Of course, during the initial ice-making phase, the water in the water tank 61 can also return to the water tank 61 along the main pipe 631 and the first branch pipe 632.

[0214] At the end of ice making, as the water in the mold cavity 10 condenses into ice, the second branch pipe 633 near the end of 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.

[0215] In some embodiments, the second branch pipe 633 includes a heat conducting pipe and a heating element connected to the heat conducting pipe; an end of the second branch pipe 633 close to the ice-making mold is connected to the mold cavity 10 through the heat conducting pipe.

[0216] It is understandable that in the initial stage of ice making, since a part of the pipe connecting the second branch pipe 633 and the mold cavity 10 will freeze, a part of the pipe connecting the second branch pipe 633 and the mold cavity 10 is designed as a heat pipe. The heat pipe can be an aluminum pipe or a stainless steel pipe, and the heating element can be an electric heating wire.

[0217] Thus, when ice making is finished, the heating element can be turned on, and the heat of the heating element is transferred to the heat pipe, which generates heat and causes the ice inside the heat pipe to melt, so as to separate the prepared ice ball from the inner wall of the mold cavity 10.

[0218] 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 may be 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm.

[0219] It is understandable that the outlet end of the second branch pipe 633 is connected to the water 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 by the second branch pipe 633 can be controlled by heating at the end of ice making. This design not only ensures the shape of the prepared ice ball, but also improves the efficiency of ice ball demolding.

[0220] In some embodiments, as Figure 20 As shown, in order to improve the efficiency of supplying water 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 .

[0221] Among them, there are two sets of second branch pipes 633, and the outlet ends of the two sets of second branch pipes 633 are connected one-to-one with the two water inlets 1011 on the same mold cavity 10. The two water inlets 1011 are centrally symmetrically distributed with respect to the axis where the water outlet 1012 of the mold cavity 10 is located. The water inlet direction of each water inlet 1011 extends downwardly at an angle relative to the horizontal plane, and is set at an angle relative to the direction of the connection line between the water inlet 1011 and the water outlet 1012 on the horizontal projection plane.

[0222] In some embodiments, the second branch line 633 includes multiple water supply branches 6331. The first ends of the multiple water supply branches 6331 are respectively connected to the main line 631, and the second ends of the multiple water supply branches 6331 are configured to communicate with multiple mold cavities 10 in a one-to-one correspondence. The length and inner diameter of each water supply branch 6331 are the same, ensuring that each water supply branch 6331 supplies approximately the same water flow rate to the corresponding mold cavity 10.

[0223] In some embodiments, as Figure 4 and Figure 14 As shown, in order to facilitate the water tank 61 to collect water returned from the water collection tank 12, the water tank 61 is set to be open and upward, and the water collection tank 12 has a diversion port 120, which is arranged 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.

[0224] In some embodiments, as Figure 4 、 Figure 16 and Figure 17 As shown, the temperature control assembly 7 includes: a heat preservation cover 71, a heating plate 72 and a fan 73; the heat preservation cover 71 is arranged on the upper side of the water collection tank 12; the heating plate 72 is arranged between the heat preservation cover 71 and the water collection tank 12 to separate a circulation air duct 701 between the heat preservation cover 71 and the water collection tank 12; the fan 73 is arranged in the circulation air duct 701, and the fan 73 is used to drive the air flow along the circulation air duct 701 to achieve convection heat exchange between the air flow and the water in the water collection tank 12. Figure 4 Arrows are used to indicate the direction of air flow along the circulating air duct 701.

[0225] It is understood that the heating plate 72 includes a heat conducting plate and multiple electric heating wires arranged on the heat conducting plate. The heat conducting plate is arranged horizontally, and the electric heating wires are arranged on the upper surface of the heat conducting plate. The upper surface of the heat conducting plate faces the top of the heat insulation cover 71, and the lower surface of the heat conducting plate faces the water collection tank 12. There is a gap between the left end of the heat conducting plate and the left side wall of the heat insulation cover 71, and between the right end of the heat conducting plate and the right side wall of the heat insulation cover 71. In this way, the heating plate 72 can separate the circulation air duct 701 between the heat insulation cover 71 and the water collection tank 12.

[0226] In actual application, at least one fan 73 is provided, and the fan 73 is arranged between the left end of the heat conduction plate and the left side wall of the thermal insulation cover 71; when the fan 73 starts to run, the airflow flows along the gap between the upper surface of the heat conduction plate and the top of the thermal insulation cover 71, and then flows through the gap between the right end of the heat conduction plate and the right side wall of the thermal insulation cover 71, and then flows through the gap between the lower surface of the heat conduction plate and the water collection tank 12. In this process, the airflow flows through the surface of the water in the water collection tank 12 and conducts convective heat exchange with the water. Then, the airflow after heat exchange flows through the gap between the left end of the heat conduction plate and the left side wall of the thermal insulation cover 71, thereby realizing circulation.

[0227] In some embodiments, as Figure 4 and Figure 17As shown, in order to facilitate the 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.

[0228] In actual application, according to the water temperature information fed back by the second temperature sensor 702, the control module can control the wind speed and on / off status of the fan 73, as well as the heating power and on / off status of the heating plate 72, to ensure that the water temperature in the water collection tank 12 is maintained between 0°C and 2°C, so as to ensure the precipitation effect of bubbles in the water without affecting the freezing speed of the water in the mold cavity 10, and also ensure the return water temperature of the mold cavity 10, preventing the water inlet 1011 of the mold cavity 10 from freezing due to too low water temperature, thereby reliably preparing transparent ice.

[0229] The control module may be a single chip microcomputer or a PLC controller. When controlling the water temperature in the water collecting tank 12, the temperature control range set by the control module is -2°C to 2°C.

[0230] In some embodiments, as Figure 22 、 Figure 23 and Figure 24 As 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 provided in the lower mold shell 21 and is arranged around the second mold cavity 102.

[0231] It is understandable that the lower mold shell 21 is configured to be combined with the upper mold shell 11 so that the first mold cavity 101 of the upper mold shell 11 and the second mold cavity 102 of the lower mold shell 21 form a closed mold cavity 10 .

[0232] Since the evaporator 22 is connected to the lower mold shell 21, and the water inlet 1011 and the water outlet 1012 are respectively arranged 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 be gradually frozen from bottom to top, thereby ensuring the molding quality of the ice ball in the mold cavity 10.

[0233] In some embodiments, as Figure 24As shown, the lower mold shell 21 includes: a second fixing frame 211, a second elastic mold shell 212 and a heat conductor 213; the second elastic mold shell 212 is detachably arranged on the second fixing frame 211, and the second mold cavity 102 is constructed on the second elastic mold shell 212; the heat conductor 213 is arranged in the second elastic mold shell 212, and at least part of the second elastic mold shell 212 and part of the heat conductor 213 are enclosed to form the second mold cavity 102; wherein, the heat conductor 213 is located at the bottom of the second mold cavity 102 and is connected to the evaporator 22.

[0234] It is understandable that the heat conducting member 213 is made of a metal material with a high thermal conductivity, for example, the heat conducting member 213 is a copper member or an aluminum member. 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 material.

[0235] Since the first elastic mold shell 112 and the second elastic mold shell 212 are assembled together and a closed mold cavity 10 is formed 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 are both lower than the thermal conductivity coefficient of the heat conductor 213, and the heat conductor 213 is located at the bottom of the mold cavity 10, the water in the mold cavity 10 freezes in an upward order, and during the freezing process, the precipitation rate of bubbles in the water in the mold cavity 10 is greater than the freezing rate of water, thereby ensuring the transparency of the prepared ice ball.

[0236] In some embodiments, as Figure 26 As shown, the embodiment of the present invention further provides a refrigeration device, comprising: a device body 8 and the ice-making device as described above, wherein the ice-making device is provided in the device body 8. The refrigeration device can be a freezer or cold storage known in the art.

[0237] Since the refrigeration equipment includes an ice-making device, the specific structure of the ice-making device refers to the above embodiment, and the refrigeration equipment of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here.

[0238] In some embodiments, as Figure 24 、 Figure 25 and Figure 26 As shown, the device body 8 has a refrigeration compartment 81 and a freezer compartment 82, and the ice-making device is arranged in the refrigeration compartment 81; the refrigeration device also includes an air guide 9, and the freezer compartment 82 is connected to the ice-making device through the air guide 9; the air guide 9 is used to guide the cold air flow in the freezer compartment 82 to the ice-making mold to promote the freezing of water in the mold cavity 10.

[0239] Specifically, for refrigeration equipment, the temperature in the freezer compartment 82 is usually lower than the temperature in the refrigeration compartment 81 . For example, the temperature in the refrigeration compartment 81 is 2° C. to 4° C., and the temperature in the freezer compartment 82 is -18° C. to -22° C.

[0240] The frame 4 of the ice-making device is arranged in the refrigeration compartment 81 and is connected to the equipment body 8; the air guide member 9 can be an insulating foam member, and a first air duct 91 and a second air duct 92 are constructed in the air guide member 9. The first air duct 91 and the second air duct 92 are isolated from each other and extended along the extension direction of the air guide member 9.

[0241] 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 arranged 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, and 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 one by one.

[0242] Thus, in actual use, the cold air in the freezing compartment 82 enters the air cavity along the first air duct 91, exchanges heat with the evaporator 22, and then returns to the freezing compartment 82 along the second air duct 92. During this process, the evaporator 22 obtains cold energy through heat exchange with the cold air flow and transfers the cold energy to the heat conducting member 213 in the lower mold shell 21, thereby controlling the freezing of water in the mold cavity 10 by using the heat conducting member 213.

[0243] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate 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 are intended to be encompassed by the claims of the present invention.
