Description

Technical Field

[0001] The invention belongs to the technical field of transparent ice manufacturing, and in particular relates to a transparent ice making mold. Background Art

[0002] With the acceleration of the pace of modern life and the improvement of the quality of life, ice cubes play an increasingly important role in many fields such as beverage cooling, food preservation, and medical cooling. Especially in beverage consumption, ice cubes can not only quickly lower the temperature of the beverage, but also maintain the original flavor of the beverage to a certain extent, and avoid diluting the beverage due to the ice cubes melting too quickly. Therefore, the quality and shape of ice cubes are of great significance to improving the drinking experience. A transparent, bubble-free ice cube melts slowly and does not affect the taste of the beverage, which greatly improves the ice-using experience. For this reason, people have proposed a partial solution for preparing transparent, bubble-free ice cubes.

[0003] For example, a Chinese invention patent with announcement number CN116907148B discloses a transparent ice making machine, including an air-cooled evaporator, an ice-making mold, a circulating pump and a warm air flow generator; the ice-making mold includes a silicone mold and a plurality of metal templates arranged at the lower end thereof, the metal templates and the silicone molds form a plurality of ice-making cavities, a riser is provided at the top of the ice-making cavity, the metal template is connected to the air-cooled evaporator, a container is provided at the 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 a plurality of ice-making cavities through a water supply pipeline, a warm air flow generator is provided above the container, the freezing starting position is close to one end of the metal template, the riser is the last freezing position of the ice-making cavity, and an escape path is provided for bubbles.

[0004] For another example, a Chinese invention patent with publication number CN117813472A discloses an ice-making assembly that may include a thermally conductive ice mold, a thermally insulated ice mold, and an external thermally insulated sleeve, wherein the thermally conductive ice mold may define a mold cavity having a vertical opening at the top of the thermally conductive mold. 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 that extends above the mold cavity and is in fluid communication with the mold cavity. The external thermally insulated sleeve may be selectively received on the thermally insulated ice mold and cover the internal water channel.

[0005] The above schemes all provide a "bottom-to-top" escape path for bubbles during the ice-making process to obtain transparent ice cubes; however, the above schemes have at least the following problems: the equipment structure is complex and the cost is high; it is inconvenient to take out the transparent ice after it is made; and the size of the mold is relatively high.

[0006] Therefore, there is an urgent need for a transparent ice-making mold that has a simple structure, lower cost, and can meet the needs of most user groups for preparing transparent ice. Summary of the invention

[0008] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: A transparent ice-making mold, comprising: an insulation shell, a mold shell and a mold body, wherein the insulation shell is provided with a first opening at the top, and a first receiving groove for installing the mold shell is provided inside the insulation shell, a second opening is provided at the top of the mold shell, and a second receiving groove for installing the mold body is provided inside the mold shell, an ice-making cavity is provided inside the mold body, the bottom of the ice-making cavity extends downward to form a water outlet channel, and the top of the ice-making cavity extends upward to form a water injection channel; When the mold shell is inserted into the first receiving groove and the mold body is inserted into the second receiving groove, a liquid storage area is formed in the gap between the mold body and the mold shell, and the water outlet channel is connected to the liquid storage area; the top of the ice-making cavity and the top of the heat-insulating shell are located at the same horizontal plane, or the top height of the ice-making cavity is lower than the top height of the heat-insulating shell; When liquid is injected from the water injection channel, the liquid passes through the water injection channel, the ice-making chamber, the water outlet channel and the liquid storage area in sequence until the ice-making chamber is filled; when making ice, freezing begins from the water injection channel, the ice-making chamber, the water outlet channel and the liquid storage area in sequence, so that bubbles in the liquid in the ice-making chamber escape to the bottom of the ice-making chamber and enter the liquid storage area, thereby making the ice cubes in the ice-making chamber transparent ice.

[0009] As an improvement, the mold body includes a first mold and a second mold of a split design, the first mold is provided with at least one first clamping piece and at least one first slot, the second mold is provided with a second slot matching the first clamping piece, and a second clamping piece matching the first slot.

[0010] 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 matching 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 in the liquid storage area is lower than the height of the first limiting slope.

[0011] As an improvement, a sealing member is provided on the circumference of the outer side of the mold body, and the sealing member is located above the second limiting inclined surface. When the mold body is embedded in the second receiving groove, the sealing member abuts against the inner wall of the mold shell.

[0012] As an improvement, the sealing member is provided with a first buffer groove on a side close to the bottom of the mold body, and a second buffer groove on a side away from the mold body, and the height of the second buffer groove is consistent with the height of the ice-making cavity.

[0013] As an improvement, the inner diameter of the mold shell gradually increases from the bottom to the top to form a mounting slope, the outer diameter of the mold body gradually increases from the bottom to the 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 radial cross-sectional area of ​​the liquid storage area gradually decreases from the bottom to the top of the mold shell.

[0014] As an improvement, the outer diameter of the mold shell gradually increases from the bottom to the top, a limiting protrusion matching the first limiting inclined surface is arranged inside the heat-insulating shell, and the top of the mold shell extends in the width direction thereof to form a limiting step; When the mold shell is embedded in the first accommodating groove, the first limiting slope 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.

[0015] 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.

[0016] As an improvement, a handle is provided on the top of the mold, and the height of the handle is higher than the height of the heat-insulating shell.

[0017] As an improvement, a heat-insulating cavity is provided inside the heat-insulating shell.

[0018] The principle and beneficial technical effect of the present invention are: the present invention provides a split quick-detachable ice-making mold, which meets the needs of most user groups for preparing transparent ice (especially preparing transparent ice at home).

[0019] Specifically, the present invention uses an outer shell with an insulation function to cover the side walls and the bottom of the ice-making chamber, thereby isolating the surroundings and the bottom of the ice-making chamber from the external cold source, to ensure that the heat exchange direction is always from top to bottom, and the crystallization direction is also from top to bottom, so that the bubbles in the liquid in the ice-making chamber escape downward into the liquid storage area, and finally transparent ice is produced.

[0020] Furthermore, by setting a mold shell between the mold body and the insulation shell to separate the two, it can be ensured that after the ice making is completed, the mold body and the mold shell can be easily removed from the insulation shell. At the same time, the mold adopts a split design. When taking ice, you only need to separate the first mold and the second mold to easily take out the transparent ice cubes inside the mold.

[0021] Furthermore, the connection parts of the mold body, the insulation shell and the mold outer shell all adopt a bevel design, and with different inclinations, the three are stably connected but their contact area is reduced, making it convenient for users to take ice or disassemble the mold.

[0028] Embodiment 1 The present invention provides a transparent ice mold, see Figure 1-3 and Figure 5 , including a heat-insulating shell 1, a mold shell 2 and a mold body 3.

[0029] See also Figure 5 and Figure 7 The insulation shell 1 is provided with a first opening at the top, and a first receiving groove 101 for mounting the mold shell is provided inside the insulation shell 1, a second opening is provided at the top of the mold shell 2, and a second receiving groove 201 for mounting the mold body is provided inside the mold shell, and an ice-making cavity 301 is provided inside the mold body 3, the bottom of the ice-making cavity 301 extends downward to form a water outlet channel, and the top of the ice-making cavity 301 extends upward to form a water injection channel 303; See also Figure 4 When the mold shell 2 is embedded in the first receiving groove, the top of the mold shell 2 and the top of the insulation shell 1 are located at the same horizontal plane; when the mold body 3 is embedded in the second receiving groove, the gap between the mold body 3 and the mold shell 2 forms a liquid storage area 4, the water outlet channel is connected to the liquid storage area 4, the top of the ice-making cavity and the top of the mold shell 2 are located at the same horizontal plane, or the top height of the ice-making cavity is lower than the top height of the mold shell; When liquid is injected from the water injection channel, the liquid passes through the water injection channel, the ice-making chamber, the water outlet channel and the liquid storage area in sequence until the ice-making chamber is filled; when making ice, freezing begins from the water injection channel, the ice-making chamber, the water outlet channel and the liquid storage area in sequence, so that bubbles in the liquid in the ice-making chamber escape to the bottom of the ice-making chamber and enter the liquid storage area, thereby making the ice cubes in the ice-making chamber transparent ice.

[0030] In some specific embodiments, the insulation shell is cylindrical, and the mold shell and the mold body are overall truncated cone-shaped. Specifically, the first receiving groove inside the insulation shell is cylindrical. When the truncated cone-shaped mold shell is embedded in the first receiving groove, there is a certain gap between the insulation shell and the mold shell, and the gap gradually decreases and contacts from the bottom of the first receiving groove to the top of the first receiving groove, so that the mold shell is only partially in contact with the insulation layer, thereby facilitating the removal of the mold body from the insulation shell.

[0031] In some embodiments, a heat preservation chamber 103 is provided inside the heat preservation shell.

[0032] In some embodiments, the inner diameter of the mold shell gradually increases from the bottom to the top to form a mounting slope, the outer diameter of the mold body gradually increases from the bottom to the 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 radial cross-sectional area of ​​the liquid storage area (that is, the cross-sectional area in the width direction of the mold) gradually decreases from the bottom to the top of the mold shell, and at the same time, the contact area between the mold body and the mold shell is also reduced, which facilitates the removal of the mold body from the mold shell.

[0033] In some embodiments, see Figure 6 The mold body is composed of two parts. Specifically, the mold body includes a first mold 304 and a second mold 305 of split design. The first mold 304 is provided with at least one first clamping piece and at least one first clamping groove. The second mold 305 is provided with a second clamping groove matched with the first clamping piece, and a second clamping piece matched with the first clamping groove. In some specific embodiments, the first mold 304 and the second mold 305 are symmetrically arranged and have the same structure, wherein the first clamping groove and the second clamping groove have the same structure, and the first clamping piece and the second clamping piece have the same structure.

[0034] In some specific embodiments, see Figure 7 The first mold and the second mold are respectively provided with two clamping grooves 307 and two clamping members 306, and the two clamping grooves 307 and the two clamping members 306 are respectively located at the four corners of the mold body. When the two molds are clamped by the clamping members and the clamping grooves, the side walls of the two molds are tightly fitted, and the ice-making cavity 301 is formed inside.

[0035] In some embodiments, the ice-making cavity is spherical, and in other embodiments, the ice-making cavity may also be a cube, a cuboid, or any other shape.

[0036] In some embodiments, see Figure 5 The side wall of the mold shell is provided with a first limiting slope 202, and the outer side of the mold body is provided with a second limiting slope 310 that cooperates with the first limiting slope 202. When the mold body is embedded in the second receiving groove, the second limiting slope 310 abuts against the first limiting slope 202, so that the liquid storage area extends from the bottom to the top of the mold shell and wraps around the outside of the mold body, and the highest liquid level of the liquid storage area is lower than the height of the first limiting slope 202, that is, lower than the highest liquid level height of the ice-making chamber, forming a liquid level difference between the ice-making chamber and the liquid storage area. On the one hand, the sealing of the liquid storage area is ensured, and on the other hand, the influence on the freezing rate of the ice-making chamber is avoided.

[0037] In some embodiments, the outer diameter of the mold shell gradually increases from the bottom to the top, a limiting protrusion 102 cooperating with the first limiting inclined surface is arranged inside the heat-insulating shell, and the top of the mold shell extends in the width direction thereof to form a limiting step 203; When the mold shell is embedded in the first accommodating groove, the first limiting slope 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.

[0038] In some embodiments, see Figure 7 A seal 5 (preferably a rubber ring) is provided on the outer circumference of the mold body, and the seal is located above the second limiting inclined surface. When the mold body is embedded in the second receiving groove, the seal abuts against the inner wall of the mold shell, thereby clamping the mold body and the mold shell to prevent the mold body from falling off the mold shell. At the same time, the seal isolates the top of the liquid storage area, that is, the side away from the bottom of the mold shell, from the outside world to prevent the liquid in the liquid storage area from flowing out from the top.

[0039] In some embodiments, the seal is provided with a first buffer groove 501 on one side close to the bottom of the mold body, and a second buffer groove 502 on the side away from the mold body, and the height of the second buffer groove 502 is consistent with the height of the ice-making cavity 301. This can provide double insurance for the sealing performance of the liquid storage area, and even if liquid accidentally flows into the first buffer groove, the second buffer groove can also separate it.

[0040] In some embodiments, see Figure 7 A transition groove 308 is provided at the bottom of the mold body. The transition groove 308 is located between the water outlet channel 302 and the liquid storage area. The width of the transition groove 308 is greater than the diameter of the water outlet channel 302.

[0041] In some embodiments, a handle 309 is provided on the top of the mold, and the height of the handle 309 is higher than the height of the heat-insulating shell. In some specific embodiments, the handle is provided on the top of the mold body and is integrally formed with the mold body.

[0042] In some embodiments, the insulation shell is made of stainless steel, the mold body is made of food-grade silicone, and a mold shell made of PET is arranged between the insulation shell and the mold body, so that the mold and the insulation shell can be separated more easily.

[0043] The transparent ice-making mold with the above structure is used as follows: first, the mold body is placed in the mold shell to form a mold assembly, and then the mold assembly is placed in the insulation shell to form an ice-making mold. Then, liquid is injected into the ice-making mold through the water injection channel at the top of the ice-making mold. The liquid fills the liquid storage area, the transition groove, the water outlet channel, the ice-making cavity (and the water injection channel) in sequence. Then, the ice-making mold is placed in an ice-making device, such as a household ice-making device (refrigerator), for refrigeration and timing. During the refrigeration process, due to the insulation effect of the external insulation shell, the cold source can only penetrate into the ice-making cavity from the top of the ice-making mold, so that the freezing direction is from top to bottom. In the process of freezing the liquid from the top of the ice-making cavity, the bubbles in the liquid below the ice cube can only escape from the bottom and finally enter the liquid storage area. When the timing is completed, the ice-making mold is taken out of the ice-making device, and the mold body can be easily taken out and split to obtain transparent ice cubes.

[0044] It should be noted that the above is only an example of one assembly method. In actual operation, the ice-making mold can also be assembled according to other assembly sequences.

[0045] Furthermore, even if the mold is not taken out of the ice-making equipment in time after ice making is completed, the freezing time of the liquid in the liquid storage area can be delayed due to the effect of the transition zone at the bottom of the mold body, thereby ensuring that the mold body can always be easily detached from the mold shell. A step back, the liquid storage area does not hold much liquid, and even if it freezes, it will have little effect on the detachment of the mold body.

[0046] See also Figure 8-Figure 10 In order to verify the heat conduction effect of the ice-making mold in this scheme, the following experiments were carried out. Specifically, Figure 8 This is the temperature distribution diagram at the initial stage of ice making. Fig. 9 This is the temperature distribution diagram in the middle stage of ice making process. Fig.10 This is a temperature distribution diagram after ice making is completed. It can be seen that as time goes by, the temperature of the liquid in the ice-making mold always keeps the top temperature lower than the bottom temperature, which confirms the effect of unidirectional crystallization from top to bottom of the mold in this application.

[0047] Furthermore, this scheme also conducts simulation tests on the cooling speed and obtains the cooling rate curve (see Fig.11 ), the horizontal axis in the figure represents the reference value of the time progress of ice formation, the vertical axis represents the reference value of the rate of temperature reduction, and the curve in the figure represents the change curve of the temperature reduction rate. It can be seen from the figure that with the increase of time, the cooling rate of the system gradually decreases and eventually stabilizes. This is because the system initially exchanges heat between the top water and the cold air, and the cooling rate is fast. Later, the water inside the mold exchanges heat with the crystallized ice, and the heat exchange rate is slow. With the progress of crystallization, it gradually stabilizes, which further confirms the unidirectional crystallization effect of the ice-making mold.

[0048] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0049] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
