Description

A transparent ice-making mold Priority application

[0001] This application claims priority to Chinese Invention Patent Application No. 2024118741257, filed on December 18, 2024, entitled "A Transparent Ice Making Mold", which is incorporated herein by reference in its entirety. Technical Field

[0002] This invention belongs to the field of transparent ice manufacturing technology, and specifically relates to a transparent ice-making mold. Background Technology

[0003] With the fast pace of modern life and the improvement of living standards, ice is playing an increasingly important role in various fields such as beverage cooling, food preservation, and medical cooling. Especially in beverage consumption, ice not only quickly lowers the temperature of drinks but also, to some extent, preserves their original flavor and prevents dilution due to rapid melting. Therefore, the quality and shape of ice are crucial for enhancing the drinking experience. A transparent, bubble-free ice cube melts slowly, does not affect the taste of the beverage, and significantly improves the ice-drinking experience. For this reason, some methods for preparing transparent, bubble-free ice cubes have been proposed.

[0004] For example, Chinese invention patent CN116907148B discloses a transparent ice maker, including an air-cooled evaporator, an ice-making mold, a circulating pump, and a warm airflow generator. The ice-making mold includes a silicone mold and several metal templates at its lower end. The metal templates and the silicone mold form several ice-making cavities. A riser is provided at the top of the ice-making cavity. The metal templates are connected to the air-cooled evaporator. A container is provided around the outer periphery of the ice-making mold. The riser is connected to a water storage tank. A circulating pump is provided in the water storage tank. The circulating pump is connected to several ice-making cavities through a water supply pipeline. A warm airflow generator is provided above the container. The starting point for freezing is the end near the metal template. The riser is the last freezing point in the ice-making cavity, providing an escape path for air bubbles.

[0005] For example, Chinese invention patent CN117813472A discloses an ice-making assembly that may include a thermally conductive ice mold, a thermally insulated ice mold, and an external thermal insulation sleeve. The thermally conductive ice mold may define a cavity having a vertical opening at its top. The thermally insulated ice mold may be selectively received on the thermally conductive ice mold and cover the vertical opening. The thermally insulated ice mold may define an internal water channel extending above the cavity and in fluid communication with it. The external thermal insulation sleeve may be selectively received on the thermally insulated ice mold and cover the internal water channel.

[0006] All of the above solutions obtain transparent ice by providing an "escape path from bottom to top" for air bubbles during the ice-making process; however, the above solutions have at least the following problems: the equipment structure is complex and the cost is high; it is inconvenient to remove the transparent ice after it is made; and the size requirements for the mold are high.

[0007] Therefore, there is an urgent need for a transparent ice-making mold that is simple in structure, lower in cost, and can meet the needs of most users for making transparent ice. Summary of the Invention

[0008] The purpose of this invention is to provide a low-cost, convenient transparent ice-making mold that partially solves or alleviates the above-mentioned shortcomings in the prior art, thereby improving the universality of ice-making molds and meeting the needs of most users for transparent ice preparation.

[0009] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0010] A transparent ice-making mold includes: an insulating shell, a mold outer shell, and a mold body. The insulating shell has a first opening at its top and a first receiving groove inside for mounting the mold outer shell. The mold outer shell has a second opening at its top and a second receiving groove inside for mounting the mold body. The mold body has an ice-making cavity inside, with a water outlet channel extending downwards at the bottom and a water injection channel extending upwards at the top. When the mold outer shell is embedded in the first receiving groove and the mold body is embedded in the second receiving groove, the distance between the mold body and the mold outer shell is... The gap forms a liquid storage area, and the water outlet channel is connected to the liquid storage area; the top of the ice-making cavity and the top of the insulation shell are located at the same horizontal plane, or the top of the ice-making cavity is lower than the top of the insulation shell; when liquid is injected from the water injection channel, the liquid passes through the water injection channel, the ice-making cavity, the water outlet channel and the liquid storage area in sequence until the ice-making cavity is full; during ice making, freezing begins in sequence from the water injection channel, the ice-making cavity, the water outlet channel and the liquid storage area, causing air bubbles in the liquid in the ice-making cavity to escape to the bottom of the ice-making cavity and enter the liquid storage area, thereby making the ice in the ice-making cavity transparent ice.

[0011] As an improvement, the mold body includes a first mold and a second mold with a split design. The first mold is provided with at least one first clamping member and at least one first slot. The second mold is provided with a second slot that cooperates with the first clamping member and a second clamping member that cooperates with the first slot.

[0012] As an improvement, the side wall of the mold shell is provided with a first limiting slope, and the outer side of the mold body is provided with a second limiting slope that cooperates with the first limiting slope; when the mold body is embedded in the second receiving groove, the second limiting slope abuts against the first limiting slope, so that the highest liquid level of the liquid storage area is lower than the height of the first limiting slope.

[0013] As an improvement, a sealing element is provided on the outer circumferential side of the mold body. The sealing element is located above the second limiting inclined surface. When the mold body is embedded in the second receiving groove, the sealing element abuts against the inner wall of the mold shell.

[0014] As an improvement, the seal is provided with a first buffer groove on the side near the bottom of the mold body and a second buffer groove on the side away from the mold body, and the height of the second buffer groove is the same as the height of the ice-making cavity.

[0015] As an improvement, the inner diameter of the mold shell gradually increases from its bottom to its top to form an installation slope, the outer diameter of the mold body gradually increases from its bottom to its top, and the inclination of the outer wall of the mold body is greater than the inclination of the inner wall of the mold shell, so that the cross-sectional area of ​​the liquid storage area in the radial direction gradually decreases from the bottom to the top of the mold shell.

[0016] As an improvement, the outer diameter of the mold shell gradually increases from its bottom to its top, the interior of the insulation shell is provided with a limiting protrusion that cooperates with the first limiting inclined surface, and the top of the mold shell extends in its width direction to form a limiting step;

[0017] When the mold shell is embedded in the first receiving groove, the first limiting inclined surface abuts against the limiting protrusion, the limiting step abuts against the top of the insulation shell, and a gap is left between the mold shell and the insulation shell.

[0018] As an improvement, a transition groove is provided at the bottom of the mold body. The transition groove is located between the water outlet channel and the liquid storage area, and the width of the transition groove is greater than the diameter of the water outlet channel.

[0019] As an improvement, the top of the mold is provided with a handle, the height of which is higher than the height of the insulation shell.

[0020] As an improvement, the insulation shell is provided with an insulation cavity inside.

[0021] The advantages of this invention are as follows: This invention provides a split, quick-release ice-making mold, meeting the needs of most users for making transparent ice (especially for home use). Specifically, this invention uses an insulated outer shell to cover the side walls and bottom of the ice-making cavity, thus isolating the ice-making cavity from external cold sources. This ensures that the heat exchange direction is always from top to bottom, and the crystallization direction is also from top to bottom, allowing air bubbles in the liquid within the ice-making cavity to escape downwards into the storage area, ultimately producing transparent ice. Furthermore, by separating the mold body and the insulated shell with a mold outer shell, it is ensured that after ice making, both the mold body and the mold outer shell can be easily removed from the insulated shell. Simultaneously, the mold's split design allows for easy removal of the transparent ice by simply separating the first and second molds. Moreover, the connecting parts of the mold body, the insulated shell, and the mold outer shell all feature a beveled design with varying inclination angles, ensuring a stable connection while reducing the contact area, facilitating ice removal or mold disassembly for the user.

[0040] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0041] Example 1: The present invention provides a transparent ice mold, as shown in Figures 1-3 and 5, including an insulation shell 1, a mold outer shell 2, and a mold body 3.

[0042] Referring to Figures 5 and 7, the top of the heat insulation shell 1 is provided with a first opening, and the interior of the heat insulation shell 1 is provided with a first receiving groove 101 for installing the mold shell 2. The top of the mold shell 2 is provided with a second opening, and the interior of the mold shell 2 is provided with a second receiving groove 201 for installing the mold body 3. The interior of the mold body 3 is provided with an ice-making cavity 301. The bottom of the ice-making cavity 301 extends downward to form a water outlet channel 302, and the top of the ice-making cavity 301 extends upward to form a water injection channel 303.

[0043] Referring to Figure 4, when the mold shell 2 is embedded in the first receiving groove 101, the top of the mold shell 2 and the top of the insulation shell 1 are on the same horizontal plane; when the mold body 3 is embedded in the second receiving groove 201, the gap between the mold body 3 and the mold shell 2 forms a liquid storage area 4, the water outlet channel 302 is connected to the liquid storage area 4, the top of the ice making cavity 301 and the top of the mold shell 2 are on the same horizontal plane, or the top height of the ice making cavity 301 is lower than the top height of the mold shell 2;

[0044] When liquid is injected through the water injection channel 303, it passes sequentially through the water injection channel 303, the ice-making cavity 301, the water outlet channel 302, and the liquid storage area 4 until the ice-making cavity 301 is full. During ice making, ice forms sequentially from the water injection channel 303, the ice-making cavity 301, the water outlet channel 302, and the liquid storage area 4. This causes air bubbles in the liquid within the ice-making cavity 301 to escape to the bottom of the ice-making cavity 301 and enter the liquid storage area 4, resulting in transparent ice in the ice-making cavity 304. Since the mold shell 2 and the mold body 3 are installed inside the insulation shell 1 and placed in the refrigeration environment, only the top injection channel 303 of the ice-making cavity 301 is connected to the external refrigeration environment. This allows ice to form gradually from the top of the ice-making cavity 301 downwards. Furthermore, during the ice-forming process, air bubbles in the ice-making liquid gradually enter the liquid storage area 4 from the water outlet channel 302, thus forming transparent ice in the ice-making cavity 301.

[0045] In some specific embodiments, the heat insulation shell 1 is cylindrical, and the mold shell 2 and the mold body 3 are generally shaped like a frustum. Specifically, the first receiving groove 101 inside the heat insulation shell 1 is cylindrical. When the frustum-shaped mold shell 2 is inserted into the first receiving groove 101, there is a certain gap between the heat insulation shell 1 and the mold shell 2. The gap gradually decreases and contacts from the bottom to the top of the first receiving groove 101, so that the mold shell 2 only partially contacts the heat insulation shell 1, thereby facilitating the removal of the mold body 3 from the heat insulation shell 1.

[0046] In some embodiments, the heat insulation shell 1 is provided with a heat insulation cavity 103 inside.

[0047] In some embodiments, the inner diameter of the mold shell 2 gradually increases from its bottom to its top to form an installation slope, the outer diameter of the mold body 2 gradually increases from its bottom to its top, and the inclination of the outer wall of the mold body 3 is greater than the inclination of the inner wall of the mold shell 2, so that the cross-sectional area of ​​the liquid storage area 4 in the radial direction (that is, the cross-sectional area in the mold width direction) gradually decreases from the bottom to the top of the mold shell 2, and at the same time reduces the contact area between the mold body 3 and the mold shell 2, making it easier to remove the mold body 3 from the mold shell 2.

[0048] In some embodiments, referring to FIG6, the mold body 3 is composed of two parts. Specifically, the mold body 3 includes a first mold 304 and a second mold 305 with a split design. The first mold 304 is provided with at least one first clamping member and at least one first slot. The second mold 305 is provided with a second slot that cooperates with the first clamping member and a second clamping member that cooperates with the first slot.

[0049] In some specific embodiments, the first mold 304 and the second mold 305 are symmetrically arranged and have the same structure. The first slot and the second slot have the same structure, and the first clamping member and the second clamping member also have the same structure.

[0050] In some specific embodiments, referring to Figure 7, the first mold 304 and the second mold 305 are respectively provided with two slots 307 and two clamping members 306. The two slots 307 and the two clamping members 306 are located at the four corners of the mold body 3. When the two molds are clamped together by the clamping members and slots, the sidewalls of the two molds fit tightly together, and an ice-making cavity 301 is formed inside. Preferably, referring to Figures 6 and 7, the first mold 304 has a first clamping member at one end of one diagonal of its isosceles trapezoidal cross-section, and a first slot at one end of the other diagonal. Correspondingly, the second mold 305 has a second slot at one end of one diagonal of its isosceles trapezoidal cross-section that engages with the first clamping member, and a second clamping member at one end of the other diagonal that engages with the first slot. By using clamping members and corresponding slots on the two diagonals, the two molds can be tightly fastened together, ensuring that the liquid inside the ice-making cavity 301 flows out only through the water outlet channel 302. In some embodiments, the size (e.g., diameter) of the first and second clamping members gradually decreases in the direction away from the mold body, thereby forming a shape similar to a frustum of a cone. Accordingly, the slot also adopts a frustum of a cone structure to further ensure the sealing between the two molds.

[0051] In some embodiments, the ice-making cavity 301 is spherical; in other embodiments, the ice-making cavity 301 may also be a cube, cuboid, or other arbitrary shape.

[0052] In some embodiments, referring to FIG5, the side wall of the mold shell 2 is provided with a first limiting slope 202, and the outer side of the mold body 3 is provided with a second limiting slope 310 that cooperates with the first limiting slope 202. When the mold body 3 is embedded in the second receiving groove 201, the second limiting slope 310 abuts against the first limiting slope 202, so that the liquid storage area 4 extends from the bottom to the top of the mold shell 2 and wraps around the outside of the mold body 3. The highest liquid level of the liquid storage area 4 is lower than the height of the first limiting slope 202, that is, lower than the highest liquid level of the ice-making cavity 301, thereby forming a liquid level difference between the ice-making cavity 301 and the liquid storage area 4. On the one hand, this ensures the sealing of the liquid storage area 4, and on the other hand, it avoids affecting the freezing rate of the ice-making cavity 301.

[0053] In some embodiments, the outer diameter of the mold shell 2 gradually increases from its bottom to its top, and the insulation shell 1 is provided with a limiting protrusion 102 that cooperates with the first limiting inclined surface 202. The top of the mold shell 2 extends in its width direction to form a limiting step 203. When the mold shell 2 is embedded in the first receiving groove 101, the first limiting inclined surface 202 abuts against the limiting protrusion 102, and the limiting step 203 abuts against the top of the insulation shell 1, so that a gap is left between the mold shell 2 and the insulation shell 1.

[0054] In some embodiments, referring to FIG7, a sealing element 5 (preferably a rubber ring) is provided on the outer circumferential side of the mold body 3. The sealing element 5 is located above the second limiting inclined surface 310. When the mold body 3 is embedded in the second receiving groove 201, the sealing element 5 abuts against the inner wall of the mold shell 2, thereby clamping the mold body 3 and the mold shell 2 to prevent the mold body 3 from falling out of the mold shell 2. At the same time, the sealing element 5 isolates the top of the liquid storage area 4, that is, the side away from the bottom of the mold shell 2, from the outside, preventing the liquid in the liquid storage area 4 from flowing out from the top.

[0055] In some embodiments, the sealing member 5 has a first buffer groove 501 on the side near the bottom of the mold body 3 and a second buffer groove 502 on the side away from the mold body 3. The height of the second buffer groove 502 is the same as the height of the ice-making cavity 301. This provides double protection for the sealing performance of the liquid storage area 4. Even if liquid accidentally flows into the first buffer groove 501, the second buffer groove 502 can still keep it out.

[0056] In some embodiments, referring to Figure 7, a transition groove 308 is provided at the bottom of the mold body 3. The transition groove 308 is located between the water outlet channel 302 and the liquid storage area 4, and the width of the transition groove 308 is greater than the diameter of the water outlet channel 302. Referring to Figure 4, since the transition groove 308 is connected to the liquid storage area 4, it can increase the liquid storage capacity of the liquid storage area 4. On the other hand, after the air bubbles are discharged from the water outlet channel 302, they can be dispersed in the transition groove 308, preventing the air bubbles from accumulating at the outlet of the water outlet channel 302.

[0057] In some embodiments, a handle 309 is provided on the top of the mold body 3, and the height of the handle 309 is higher than the height of the heat insulation shell 1. In some specific embodiments, the handle 309 is provided on the top of the mold body 3 and is integrally formed with the mold body 3.

[0058] In some embodiments, the heat insulation shell 1 is made of stainless steel, the mold body 3 is made of food-grade silicone, and a PET mold shell 2 is set between the heat insulation shell 1 and the mold body 3, which makes it easier to separate the mold body 3 and the heat insulation shell 1.

[0059] In practical use, the transparent ice-making mold with the above structure is first placed into the mold shell 2 to form a mold assembly. Then, the mold assembly is placed into the insulation shell 1 to form an ice-making mold. Liquid is then injected into the ice-making mold through the water injection channel 303 at the top of the ice-making mold. The liquid sequentially fills the liquid storage area 4, the transition tank 308, the water outlet channel 302, and the ice-making cavity 301 (and the water injection channel 302). The ice-making mold is then placed into an ice-making device, such as a household ice-making device (refrigerator), for cooling and timing. During the cooling process, due to the insulation effect of the external insulation shell 1, the cold source can only seep into the ice-making cavity 301 from the top of the ice-making mold. In this way, the freezing direction is from top to bottom. During the process of the liquid freezing from the top of the ice-making cavity 301, the air bubbles in the liquid below the ice block can only escape from the bottom and eventually enter the liquid storage area 4. When the timing is completed, the ice-making mold is removed from the ice-making device, and the mold body 3 can be easily removed and disassembled to obtain transparent ice blocks.

[0060] It should be noted that the above is just an example of one assembly method. In actual operation, ice molds can also be assembled according to other assembly sequences.

[0061] Furthermore, even if the mold is not removed from the ice-making equipment in time after ice making is completed, the transition zone at the bottom of the mold body can delay the freezing time of the liquid in the storage area, thus ensuring that the mold body can always be easily detached from the mold shell. To put it another way, the storage area does not hold a large amount of liquid, so even if it freezes, it will not have much impact on the detachment of the mold body.

[0062] Referring to Figures 8-10, the following experiments were conducted to verify the heat conduction effect of the ice-making mold in this scheme. Specifically, Figure 8 is the temperature distribution diagram in the initial stage of ice making, Figure 9 is the temperature distribution diagram in the middle stage of ice making, and Figure 10 is the temperature distribution diagram after ice making is completed. It can be seen that as time increases, the liquid temperature in the ice-making mold always keeps the top temperature lower than the bottom temperature, which confirms the unidirectional crystallization effect of the mold from top to bottom in this application.

[0063] Furthermore, this scheme also conducted simulation experiments on the cooling rate, obtaining a cooling rate curve (see Figure 11). In the figure, the horizontal axis represents the reference value of the freezing time progress, and the vertical axis represents the reference value of the temperature reduction rate. The curve in the figure shows the change curve of the temperature reduction rate. As can be seen from the figure, as time increases, the cooling rate of the system gradually decreases and eventually tends to stabilize. This is because the system initially exchanges heat between the top water and the cold air, resulting in a faster cooling rate. Later, the heat exchange occurs between the water inside the mold and the crystallized ice, which is slower. As the crystallization process progresses, the cooling rate gradually stabilizes, further confirming the unidirectional crystallization effect of the ice-making mold.

[0064] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
