Abstract
Description
Technical Field
[0001] This application relates to the technical field of ice makers, and in particular to an ice-making module and an ice maker. Background Technology
[0002] In recent years, with the increasing integration of functions in household water purification equipment, multi-functional water purifiers with ice-making capabilities have become a new market trend. Currently, mainstream models generally adopt ice-making cartridge-type ice preparation systems, which use a refrigeration module to perform phase change cooling on the water storage chamber to form regular ice.
[0003] However, traditional ice-making processes have significant drawbacks: during the gradual freezing process, dissolved gases are trapped in the gaps between ice crystals due to the lack of an effective escape path, resulting in bullet ice with a milky white, misty structure. This type of ice melts faster than transparent ice due to lattice defects, which seriously affects the user experience.
[0004] In related technologies, a micro-circulation pump is integrated into the ice-making chamber to induce gas precipitation through forced water flow disturbance, thereby producing transparent ice. However, its unidirectional flow channel design causes water flow disturbance, resulting in disordered ice crystal growth and the formation of irregular interfaces on the ice surface. Furthermore, the added circulation pump assembly increases the overall manufacturing cost and introduces additional continuous power consumption. Utility Model Content
[0005] Therefore, it is necessary to provide an ice-making module and ice maker to address the problems of low ice flatness, inconsistent ice shape, and high production and operating costs of the ice produced.
[0006] Firstly, this application provides an ice-making module, which adopts the following technical solution:
[0007] An ice-making module includes an ice-making box, an ice-making tray, and a water inlet pipe. The ice-making box has an ice-making cavity, a water inlet, and a drain hole. The water inlet and the drain hole are both connected to the ice-making cavity. The water inlet is used to supply external water to the ice-making cavity, and the drain hole is used to discharge water from the ice-making cavity. The ice-making tray is located above the ice-making box and extends downwards into the ice-making cavity in at least part. The ice-making tray is used to freeze the water in the ice-making cavity into ice. The water inlet pipe is used to supply external water to the ice-making cavity. The water inlet pipe has a water supply port. Water discharged through the water supply port is inclinedly input into the ice-making cavity and forms a vortex within the ice-making cavity.
[0008] In one embodiment, the water inlet pipe has multiple water outlets, all of which are arranged at circumferential intervals along the water inlet. Each water outlet is configured to be inclined from the water inlet toward the ice-making cavity, and the inclination direction of the water outlet is consistent with the formation direction of the vortex.
[0009] In one embodiment, the ice-making box has multiple pairs of lower drain holes, each pair of lower drain holes being symmetrically arranged along the longitudinal direction of the ice-making box; the lower drain holes penetrate the bottom wall of the ice-making box so that water injected into the ice-making box can flow out of the ice-making cavity through the lower drain holes.
[0010] In one embodiment, the ice maker includes an overflow outlet that extends through the side wall of the ice maker and connects to the water inlet.
[0011] In one embodiment, the ice maker includes a plurality of overflow ports, all of which are spaced apart circumferentially along the ice maker; the overflow ports penetrate the side wall of the ice maker and are connected to the water inlet.
[0012] In one embodiment, the ice-making module further includes an ice water storage box, the ice-making box being located above the ice water storage box, and water in the ice-making cavity being able to flow into the ice water storage box through the lower drain hole.
[0013] In one embodiment, the ice-making module further includes a circulating water pump connected between the water inlet end of the water inlet pipe and the ice water storage box.
[0014] In one embodiment, the ice-making module further includes a first support member and a second support member, which are respectively connected to opposite ends of the ice-making box and installed in the ice water storage box.
[0015] In one embodiment, the ice-making tray has a plurality of ice-making columns arranged at intervals, the ice-making columns extending downward into the ice-making cavity and being able to contact the water in the ice-making cavity.
[0016] Secondly, this application provides an ice maker, which adopts the following technical solution:
[0017] An ice maker includes a condenser, a compressor, and the aforementioned ice-making module, wherein the condenser and the compressor are both connected to the ice-making tray.
[0018] The aforementioned ice-making module uses an inclined water inlet pipe to create a circular flow of water within the ice-making container. This water flow disturbance induces gas release, resulting in the production of transparent ice. During the process, the water flow disturbance relies entirely on the circulating flow of eddies, producing a smooth and rounded ice surface. Furthermore, no additional motor equipment is required, leading to low manufacturing and operating costs. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Currently, most mainstream ice-making machines use bullet ice preparation methods, with conventional ice-making structures employing either closed ice boxes or open ice trays to achieve phase change refrigeration. However, this traditional ice-making process has significant drawbacks: during the layer-by-layer freezing process, dissolved gases in the water cannot effectively escape and instead form microbubbles that aggregate, resulting in a milky white, opaque ice crystal. This type of ice crystal not only has poor thermodynamic stability and a rapid melting rate, but its cloudy appearance also fails to meet the quality requirements of high-end users.
[0033] To improve ice transparency, existing technologies often incorporate a miniature circulating water pump within the ice-making chamber to accelerate bubble formation through forced water flow disturbance. However, this approach reveals several technical contradictions in practical applications: First, the unidirectional flow channel design leads to uneven water flow disturbance, resulting in a non-uniform freezing layer due to the continuous drop in water level during ice growth, leading to poor surface smoothness and low geometric consistency in the finished ice. Second, the integration of the auxiliary pump significantly increases system complexity and manufacturing costs, while also incurring additional energy consumption and maintenance requirements. These technical shortcomings severely restrict the large-scale application of transparent ice preparation technology in household water purification equipment.
[0034] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.
[0035] See Figure 1 , Figure 1 This illustration shows a three-dimensional structural diagram of an ice maker according to an embodiment of this application. One embodiment of this application provides an ice-making module, including an ice-making box 1 with an ice-making cavity 11. The ice-making cavity 11 penetrates the top wall of the ice-making box 1 to form a water inlet 12, and a lower drain hole 14 penetrates the bottom of the ice-making box 1. An external water source can be input into the ice-making cavity 11 through the water inlet, and the lower drain hole 14 is used to output water from the ice-making cavity 11 to the outside, ensuring the fluidity of the water flow inside the ice-making cavity 11, thereby improving the transparency of the prepared ice. Furthermore, the ice-making module also includes an ice-making tray 2 disposed above the ice-making box 1. The ice-making tray 2 extends at least partially downward into the ice-making cavity 11 to condense the water in the ice-making cavity 11 into ice, thereby realizing the ice-making operation.
[0036] Combination Figure 2 and Figure 3 As shown, Figure 2 A top view of an ice maker according to an embodiment of this application is shown. Figure 3 The image shows a side view of an ice maker according to one embodiment of this application. In some embodiments, the ice-making module further includes a water inlet pipe 3 and a circulating water pump 5 for inputting external water into the ice-making chamber 11. The water inlet pipe 3 includes a main water inlet pipe 31 and a first water inlet branch pipe 32 and a second water inlet branch pipe 33 connected to the outlet of the main water inlet pipe 31. The circulating water pump 5 is installed on the main water inlet pipe 31, and the inlet end of the main water inlet pipe 31 is connected to an external water source to achieve continuous water supply during the ice-making process.
[0037] Among them, the circulating water pump 5 includes, but is not limited to, a common unidirectional centrifugal pump.
[0038] Specifically, the water outlets 34 of the first water inlet branch pipe 32 and the second water inlet branch pipe 33 have opposite water outlet directions and are spaced apart along the circumference of the ice-making box 1. In this embodiment, the water output from the first water inlet branch pipe 32 and the second water inlet branch pipe 33 is inclinedly injected into the ice-making chamber 11, forming an annular water flow, i.e., a vortex, within the ice-making chamber 11. This allows gas to be released from the water by disturbing the water flow, thereby achieving the purpose of preparing transparent ice.
[0039] See also Figure 2 As shown in the embodiment of this application, the first water injection branch pipe 32 injects water towards the left side of the ice box 1, and the second water injection branch pipe 33 injects water towards the right side of the ice box 1, so that the water injected into the ice-making cavity 11 through these two water injection branch pipes forms a counterclockwise circulation.
[0040] It is understood that in some other embodiments, by adjusting the water outlet 34 of the first water injection branch pipe 32 and the second water injection branch pipe 33, a clockwise circulation can also be formed in the ice-making cavity 11, as long as the formed circulation can continuously pass through the ice-making plate 2.
[0041] The ice-making module, with the structural design shown in this application, achieves its ice-making process entirely through two incoming flows from different directions, resulting in a smooth and rounded ice surface. Furthermore, the entire ice-making module requires no additional motor equipment, offering significant advantages in terms of low manufacturing and operating costs.
[0042] Continue reading Figure 1 As shown in the embodiment of this application, the ice-making tray 2 includes a main body 21 disposed above the ice-making box 1 and a plurality of ice-making columns 22 connected to the main body 21. All the ice-making columns 22 are connected to the bottom of the main body 21 and are spaced apart from each other. The ice-making columns 22 extend downward into the ice-making cavity 11 and are at least partially submerged in water so that ice blocks can be condensed on the periphery of the ice-making columns 22 during the ice-making process.
[0043] During the ice-making process, the shape of the ice cubes changes depending on the shape of the ice column 22 on the ice-making tray 2. For example, when the ice column 22 of the ice-making tray 2 is designed as a cylinder, the resulting ice cubes are classic cylindrical ice; if the ice column 22 is a cube, square ice cubes will be produced; when the ice column 22 is a slender prism, the resulting ice cubes will be elongated; some ice-making trays 2 also design the ice column 22 into fun shapes such as stars and flowers. These irregularly shaped ice cubes often appear in creative drinks or festive specials, adding visual appeal and fun to the drinks and meeting consumers' needs for personalization and diversity.
[0044] Combination Figures 4 to 5 As shown, Figure 4 This paper shows a three-dimensional structural diagram of the ice-making box 1 according to an embodiment of the present application. Figure 5 A top view of an ice-making container 1 according to an embodiment of this application is shown.
[0045] In some embodiments, the ice container 1 has an overflow port 13 on its side wall, which extends through the side wall and connects to the water inlet 12 of the ice container 1. During the ice-making process, when the water level in the ice container 1 reaches or slightly exceeds the height of the overflow port 13, excess water in the ice container 1 will flow out through the overflow port 13, ensuring that the highest water level in the ice container 1 never exceeds the upper end of the overflow port 13, thus maintaining a constant water level in the ice container 1 and improving the smoothness of the surface of the produced transparent ice.
[0046] In some other embodiments, multiple overflow ports 13 may be provided, with all overflow ports 13 arranged at intervals along the circumference of the inlet 12. See also... Figure 4 As shown in the embodiment of this application, each ice container 1 is provided with two overflow ports 13. The two overflow ports 13 are arranged diagonally on the ice container 1, and the overflow height is the same. Specifically, the overflow height refers to the water level in the ice container 1 when water is discharged from the overflow port 13.
[0047] See Figure 5 As shown, in some other embodiments, the lower drain hole 14 can also be provided in multiple pairs, each pair of lower drain holes 14 being along the longitudinal direction of the ice container 1. Figure 5 The ice blocks are arranged symmetrically in the left and right directions to ensure the uniformity of water flow at the bottom of the ice-making cavity 11 during the ice-making process, thereby improving the regularity of the prepared ice blocks.
[0048] During actual ice making, after the circulating water pump 5 is powered on, external water is injected into the ice-making container 1 through the inlet pipe 3. During the injection process, the two water streams injected through the first water injection branch pipe 32 and the second water injection branch pipe 33 gradually form a circular water flow. At this time, the drain hole 14 starts to work, gradually discharging the injected water outward through the drain hole 14. At this time, the water supply rate is greater than the draining rate. After a period of water injection, the water in the ice-making container 1 gradually fills to the overflow port 13. At this time, the overflow port 13 starts to work, and gradually, the water injection volume = draining volume + overflow volume, so that the water level in the ice-making container 1 remains constant. At this time, ice blocks gradually form around the ice-making column 22 of the ice-making tray 2.
[0049] In this embodiment, the water flow is formed at an angle through the lower drain hole 14 and the water inlet 34, making it easier for air bubbles to dissipate, thereby improving the overall transparency and smoothness of the ice cubes. Furthermore, the overflow outlet 13 ensures that the water level remains stable during ice making. Therefore, the ice cubes prepared in this way can guarantee consistent shape and length, and their transparency can also be guaranteed.
[0050] See Figure 1 and Figure 2As shown, in some embodiments, the ice-making module further includes an ice water storage box 4 for storing external water sources, so as to... Figure 1 As shown in the example, the ice water storage box 4 is constructed as a rectangular box-shaped structure with an opening at the top. The ice-making box 1 and the ice-making tray 2 are both located above the ice water storage box 4 and are movably installed on the ice water storage box 4.
[0051] In the actual ice-making process, the inlet end of the water injection main pipe 31 extends into the ice water storage box 4, and the outlet end is used to connect the inlet ends of the first water injection branch pipe 32 and the second water injection branch pipe 33. Driven by the circulating water pump 5, the ice water in the ice water storage box 4 is injected into the ice-making chamber 11 through the water supply ports 34 of the first water injection branch pipe 32 and the second water injection branch pipe 33, and at the same time, a ring-shaped water flow is formed in the ice-making chamber 11, causing the water level in the ice-making chamber 11 to gradually rise.
[0052] Meanwhile, some water in the ice-making chamber 11 flows out through the lower drain hole 14 and is re-injected into the ice water storage box 4. During this process, the water supply of the inlet pipe 3 is greater than the leakage of the lower drain hole 14 to ensure a continuous rise in the water level in the ice-making chamber 11. As the water level rises to the height of the overflow port 13, some water in the ice-making chamber 11 overflows through the overflow port 13 and flows back into the ice water storage box 4, achieving water recycling. During this process, the water supply of the inlet pipe 3 is equal to the leakage plus the overflow, so that the water level in the ice-making box 1 remains stable during the ice-making process, keeping the water surface stable on a flat plane and preventing depressions as ice is made.
[0053] Continue reading Figure 1 and Figure 2 As shown, in some embodiments, the ice-making module further includes a first support member 6 and a second support member 7, which are respectively connected to opposite ends of the ice-making box 1 and installed on the side wall of the ice water storage box 4, so that the ice-making box 1 is mounted on top of the ice water storage box 4.
[0054] Specifically, the ice water storage box 4 has a first mounting notch (not shown) and a second mounting notch (not shown) on its side wall. The first support member 6 is installed in the first mounting notch, and the second support member 7 is installed in the second mounting notch. The first support member 6 and the second support member 7 are both constructed as cylindrical structures and are coaxially arranged along the central axis of the ice box 1.
[0055] In some embodiments, the ice-making module further includes a drive member 10 disposed on one side of the ice-making container 1. The drive member 10 is tractively connected to a first support member 6. Under the drive of the drive member 10, the first support member 6 can rotate along the axis and cause the ice-making container 1 to flip, thereby pouring out the ice cubes in the ice-making container 1. In other embodiments, the drive member 10 is tractively connected to a second support member 7. Under the drive of the drive member 10, the second support member 7 can rotate along the axis and cause the ice-making container 1 to flip, which can also pour out the ice cubes in the ice-making container 1.
[0056] In this embodiment, the driving component 10 includes, but is not limited to, a common drive motor.
[0057] In some embodiments, the ice-making module further includes an ice storage mechanism (not shown) disposed between the ice-making box 1 and the ice-water storage box 4. Specifically, the ice-making box 1 may be an open box with a radial cross-section of semi-circular, so that the ice blocks made can be poured into the ice storage mechanism by means of the flipping of the ice-making box 1 after ice making is completed.
[0058] In this embodiment, the ice storage mechanism is located directly below the ice-making box 1, along the longitudinal direction of the ice-making box 1. Figure 5 In the left-right direction (as shown), the size of the ice storage mechanism is smaller than the size of the ice container 1, that is, from Figure 5 As shown in the view, the longitudinal dimension of the ice storage mechanism is smaller than that of the ice-making box 1. In order to prevent water flowing out through the lower drain hole 14 during the ice-making process from falling into the ice storage mechanism, in this embodiment, all the lower drain holes 14 are located at opposite ends in the longitudinal direction of the ice-making box 1, avoiding the ice storage mechanism located directly below the ice-making box 1, so that the water flowing out from the lower drain hole 14 falls directly into the ice water storage box 4.
[0059] Combination Figures 1 to 5 As shown, in some embodiments, this application also provides an ice maker, which includes a condenser 8, a compressor 9, and an ice-making module as shown in any of the above embodiments. Both the condenser 8 and the compressor 9 are connected to the ice-making tray 2 of the ice-making module. During ice making, the compressor 9 operates, and heat exchange occurs between the condenser 8 and the ice-making tray 2 to achieve the ice-making operation.
[0060] In the actual ice-making process, after the circulating water pump 5 is powered on, the ice water in the ice water storage box 4 is injected into the ice-making box 1 through the circulating water pump 5 and the water inlet pipe 3. At this time, the compressor 9 starts to work. As the ice water is gradually injected into the ice-making box 1 through the first water injection branch pipe 32 and the second water injection branch pipe 33, a ring-shaped water flow is gradually formed in the ice-making box 1, and the gas entrained in the ice water is released, thereby improving the transparency of the prepared ice. At the same time, the lower drain hole 14 starts to work, and the ice water in the ice-making chamber 11 is reinjected into the ice water storage box 4 through the lower drain hole 14, and the water supply speed is greater than the lower drain speed.
[0061] After a period of time, the water in the ice-making chamber 11 gradually fills to the overflow port 13 and overflows outward through the overflow port 13, flowing back into the ice-water storage box 4. At this time, ice gradually forms around the ice-making column 22. Gradually, the water supply will equal the sum of the leakage and overflow, realizing water circulation.
[0062] In the ice-making process of the ice-making machine as shown in this application, the counterclockwise circulating water flow formed by the lower drain hole 14 and the water supply port 34 at an angle makes it easy for air bubbles to dissipate, thereby improving the transparency of the prepared ice. The design of the overflow port 13 ensures that the horizontal plane inside the ice-making chamber 11 remains stable during ice making, thereby ensuring the consistency of the shape and length of the prepared ice blocks and improving the quality of the ice blocks.
[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
