[0026] Preferred embodiments of the present application will be described in greater detail below, with reference to the drawings. While the preferred embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0027] To solve the above problems, the present embodiment provides an ice making mold which can produce ice blocks with transparent top and periphery and opaque bottom center.

[0028] As shown in Figs. 1-3 An ice making mold comprises:

[0029] A forming unit having an upper mold 1, a lower mold 2 and a forming cavity 3, the upper mold 1 and the lower mold 2 are assembled to form the forming cavity 3;

[0030] An outer sleeve 4 with an open top end for accommodating the support forming unit;

[0031] The outer sleeve 4 and the forming unit are assembled, and the inner wall of the outer sleeve 4 and the outer wall of the forming unit form a temperature insulation part 6;

[0032] The thickness of the temperature insulation part 6 increases from the top of the inner wall of the outer sleeve 4 to the bottom of the forming unit.

[0033] In the present embodiment, the temperature insulation part 6 is an air sandwich.

[0034] In the present embodiment, the temperature insulation part 6 comprises an upper temperature insulation part and a lower temperature insulation part connected in series, the upper temperature insulation part is located on the outer periphery side of the forming unit, and the lower temperature insulation part is located on the bottom of the forming unit, and the thickness of the upper temperature insulation part increases from top to bottom.

[0035] In the prior art, when making transparent ice blocks, transparent ice areas and opaque "white turbidity" areas are formed inside the ice blocks.

[0036] During the water freezing process, gas is precipitated to form bubbles, and the frozen part will drive the bubbles to the unfrozen part, and finally the bubbles gather in the area where the water is last frozen in the mold, which is an opaque white turbidity area, and outside the white turbidity area, a transparent ice area is formed.

[0037] In order to obtain as much transparent ice as possible, the interface between the white turbidity area and the transparent ice area needs to be as flat as possible to facilitate segmentation. The existing method is to wrap the bottom and sides of the mold with thick thermal insulation material to ensure that no cold enters from the sides and bottom during freezing, leaving only the top plane of the mold as the exposed cold surface. This allows the liquid near the side wall of the forming cavity 3 to not receive additional cold from the side wall during freezing, so it does not freeze faster than the liquid near the center at the same level. Therefore, the liquid at the same level freezes simultaneously, so the ice freezing process is formed layer by layer from top to bottom, and the interface between the white turbidity area and the transparent ice area is a flat plane.

[0038] This ice making method makes the interface between the white turbidity area and the transparent ice area approximately a flat plane, making the white turbidity area more rigid and having low aesthetic value.

[0039] Referring to Figs. 1-2 When used, the outer sleeve body 4 and the lower mold 2 are connected to form a thermal insulation part 6, then the liquid to be frozen is poured into the lower mold 2, then the upper mold 1 is installed on the lower mold 2 to form a forming cavity 3, and the liquid to be frozen fills the forming cavity 3, and finally the mold is placed in the freezer to freeze the ice.

[0040] The thickness of the thermal insulation part of the ice making mold increases from the top of the inner wall of the outer sleeve body 4 to the bottom of the forming unit, and the thermal insulation part 6 can control the contact sequence of different positions of the forming cavity 3 with cold air, thereby preparing ice blocks with transparent top and periphery and opaque center. At the beginning of freezing, the liquid in the forming cavity 3, its top first contacts the cold air and freezes first, then the liquid in the forming cavity 3 freezes from top to bottom, the top freezes first, the periphery freezes second, the center freezes third, and the bottom freezes last. In this way, the bubbles in the liquid are forced to gather in the middle and bottom of the forming cavity 3, and finally form an opaque ice block area like a mountain peak, while the top and periphery areas form transparent ice block areas because they do not contain bubbles.

[0041] Specifically, at the beginning of freezing, the liquid in the forming cavity 3 mainly receives cold from the area not covered by the thermal insulation part 6. Since the area not covered by the thermal insulation part 6 accounts for a relatively small proportion of the total surface area of the forming cavity 3, less cold is transferred from this area, and the freezing speed is slower. The gas bubbles generated during freezing are discharged to the surrounding unfrozen area, and at this time, the area forms a transparent ice block. In the subsequent freezing process, the area covered by the thermal insulation part 6 also continuously transfers cold from the top to the bottom of the forming cavity 3 through the already frozen ice block. Therefore, overall, the liquid in the forming cavity 3 freezes from top to bottom, and the bubbles in the first frozen area can move to the frozen area. The first frozen area forms a transparent ice block, while the later frozen area receives the discharged bubbles, and the gas density is high. At the same time, when the area freezes, the remaining part of the forming cavity 3 has already frozen into ice, and it is difficult for the bubbles to move further. Therefore, the bubbles are finally contained in the later frozen area, which forms an opaque area. Finally, after the liquid in the forming cavity 3 completely freezes, an ice block with a transparent top and an opaque bottom is formed.

[0042] In the present application, the thermal insulation part 6 is designed to be thinner at the top than at the bottom. Therefore, as the freezing process progresses, a small amount of cold is also transferred to the mold side wall near the top of the thermal insulation part 6. The liquid near this side wall in the forming cavity 3 not only receives the cold transferred from top to bottom as described above, but also receives additional cold from the top of the mold side wall. Therefore, the liquid near this side wall freezes earlier than the liquid near the center at the same horizontal plane, and the liquid in the center of the forming cavity 3 freezes later. The area at the bottom of the forming cavity 3 freezes last because the surrounding thermal insulation part 6 is thicker. Furthermore, when the ice block is frozen using the present application, the liquid in the forming cavity 3 not only freezes from top to bottom, but also simultaneously undergoes an inward freezing process in the areas other than the bottom. The bubbles discharged from the first frozen area are concentrated in the center and bottom areas of the forming cavity 3, which freeze last. As a result, when the freezing is completed, the top and surrounding areas form transparent ice block areas, while the bottom and center areas form opaque areas. The center area is higher than the bottom area, so the opaque areas appear to be higher in the center and lower around the periphery, forming a mountain shape and bringing a unique aesthetic appeal.

[0043] In the present embodiment, a pressure-activated automatic drainage channel 22 is also included. The lower mold 2 is provided with the drainage channel 22, and the thermal insulation part 6 is connected to the forming cavity 3 through the drainage channel 22.

[0044] In one embodiment of the present embodiment, the lower mold is made of a soft material, and the drainage channel 22 is a slit hole. It should be noted that the lower mold is a silicone piece, and the drainage channel 22 is a slit hole opened at the bottom of the lower mold. The slit hole is opened to release pressure when the internal pressure of the forming cavity increases. The volume of water frozen into ice will increase, and if pressure is not released, the forming unit and the ice block will be pressed against each other during the freezing process, causing the ice block to be subjected to a large pressure and possibly causing cracks or even breaking of the ice block.

[0045] When the liquid in the forming cavity 3 is not frozen, the pressure in the forming cavity 3 has not increased, the liquid discharge channel 22 is not opened, and the liquid cannot enter the air layer through the liquid discharge channel 22. As the temperature of the liquid (water) in the forming cavity 3 gradually decreases, the gas in the liquid is precipitated, and as the water freezes, the gas cannot be contained in the ice crystals, and thus gradually precipitates and forms bubbles. The pressure in the forming cavity 3 gradually increases, the liquid discharge channel 22 is squeezed open, and part of the liquid and bubbles enter the air layer from the liquid discharge channel 22.

[0046] Therefore, during the freezing process, the pressure in the forming cavity 3 can be kept in a low range, reducing the squeezing of the ice block during the ice block forming process and reducing the risk of cracks in the ice block.

[0047] In another embodiment in the present embodiment, the lower mold 2 is made of a hard material. When the lower mold 2 is made of a hard material, an embedded part 5 with a one-way valve function needs to be provided at the bottom of the lower mold 2, and the liquid discharge channel 22 is provided on the embedded part 5. The embedded part 5 can be a one-way valve or a silica gel part. When the embedded part is a silica gel part, the liquid discharge channel 22 is a slit hole.

[0048] When the ice block is demolded, the user usually likes to use a twisting method to make the mold and the ice block slide relative to each other, thereby facilitating demolding. When the lower mold 2 is made of a hard material such as hard plastic or metal alloy, the user can more easily apply a twisting force to the lower mold 2 relative to the lower mold 2 made of a soft material, and thus the user can obtain a better use experience.

[0049] In the present embodiment, the forming cavity is spherical, and the inner wall of the upper mold 1 and the inner wall of the lower mold 2 form a complete spherical surface after the upper mold 1 and the lower mold 2 are spliced.

[0050] In the present embodiment, the upper mold 1 is provided with an upper side hole 11.

[0051] Before ice making, the liquid to be frozen needs to be poured into the lower mold 2. Sometimes, the amount of the liquid to be cooled in the lower mold 2 exceeds the required amount. When the upper mold 1 is covered on the lower mold 2, a large amount of liquid will flow out from the joint between the upper mold 1 and the lower mold 2, and the liquid remaining at the joint will freeze into ice during the freezing process. The ice adhering to the upper mold 1 and the lower mold 2 will make it difficult to separate the upper mold 1 and the lower mold 2.

[0052] In the present ice making mold, the upper mold 1 is provided with an upper side hole 11. When the amount of the liquid to be cooled exceeds the required amount, the excess liquid to be frozen will flow out from the upper side hole 11, avoiding a large amount of liquid remaining at the joint and increasing the difficulty of separating the upper mold 1 and the lower mold 2 after the ice is frozen.

[0053] In the present embodiment, the opening of the bottom end of the upper mold 1 is smaller than the large circle of the spherical surface on which the upper mold 1 is located. The widest part of the opening of the bottom end of the upper mold 1 is smaller than the diameter of the large circle of the spherical surface on which the upper mold 1 is located. After the ice ball is made by the spherical forming cavity 3, it is inconvenient to take out the ice ball because the ice ball is smooth. The opening of the upper mold 1 is arranged as a downward opening, and the widest part of the opening is smaller than the large circle of the spherical surface on which the upper mold 1 is located (here, the large circle refers to the intersection line of the plane passing through the center of the ball and the spherical surface), so that after the freezing is completed, the upper mold 1 can clamp the ice ball from top to bottom, facilitating the taking out of the ice ball.
