Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

FIG. 1 is a schematic diagram of the ice-making mold of the present invention before being fastened, and FIG. 2 is a schematic cross-sectional view of the ice-making mold in FIG. 1.

The present invention provides an ice-making mold 100, which is suitable for preparing transparent ice. The following will take the ice making mold 100 to prepare spherical transparent ice as an example to illustrate the structure and the method of making spherical transparent ice, but it is not limited thereto.

It should be understood that, in other embodiments of the present invention, various shapes of transparent ice can be formed by changing the shape of the base of the ice-making mold and the water storage tank in the upper cover.

As shown in Figures 1 and 2, the ice-making mold 100 includes a base 10 and an upper cover 20, wherein the thermal conductivity of the base 10 is greater than that of the upper cover 20, so that the ice-making mold 100 is heated during the ice making process. It gradually freezes from the first water storage tank 12 of the base 10 toward the second water storage tank 22 of the upper cover 20 to form transparent ice.

Preferably, the base 10 is, for example, a metal base, a plastic base, etc., the metal base is made of aluminum or aluminum alloy material, for example; the plastic base is made of polyethylene (PP) material, for example; The upper cover is made of materials with poor performance and good heat insulation performance.

Continuing to refer to Figures 1 and 2, the base 10 includes a first body 11 formed with a first water storage tank 12 on the first body 11. The first water storage tank 12 includes a first hemispherical groove 121 located at the bottom and a column located at the top The first hemispherical groove 121 and the cylindrical groove 122 communicate with each other, wherein the groove wall part of the cylindrical groove 122 is arranged around the outer wall of the first hemispherical groove 121, so that the first hemispherical groove 121 The first edge 1211 protrudes from the inner side of the groove wall of the cylindrical groove 122.

The cylindrical groove 122 protrudes from the first side of the first body 11, and the top of the groove wall of the cylindrical groove 122 is higher than the first edge 121. In addition, the top of the wall of the cylindrical tank 122 has an overflow port 123, and the overflow port 123 is used to make the volume of the first water storage tank 12 equal to 90% of the volume of the transparent spherical ice to be prepared. This is because the density of ice is about 0.9 of that of water, and the volume of water increases after it freezes. Taking into account the volume change caused by the above-mentioned phase change, the overflow 123 maintains the volume of the first water storage tank 12 at the transparent level to be prepared. 90% of the volume of the spherical ice, water exceeding this part of the volume flows out from the overflow port 123.

The base 10 is provided with a drain hole 14, and the drain hole 14 may be formed on the first body 11 to drain the water flowing out from the overflow port 123. In this embodiment, the drain hole 14 is formed at the corner of the first body 11, but it is not limited to this.

A first extension portion 13 is provided on one side of the first body 11, and the first extension portion 13 extends toward the upper cover 20. The first extension portion 13 is provided around the edge of the first body 11.

After the upper cover 20 and the base 10 are buckled with each other, the lower area of the upper cover 20 is combined in the accommodating space.

In other embodiments of the present invention, the drainage hole can also be provided on the first extension part, or the drainage hole can also be provided at the junction of the first extension part and the first body. That is, the drainage hole can be substantially provided on the first body and/or the first extension portion.

A second extension 15 is provided on the opposite side of the first body 11, and the second extension 15 extends toward and away from the upper cover 20. The second extension portion 15 is arranged around the edge of the first body 11, where the first body 11 is, for example, a quadrilateral shape, and the second extension portion 15 corresponds to the quadrilateral shape and includes a plurality of extension walls, each of which is provided with at least one channel Hole 16. Among them, at least one through hole 16 allows cold air to circulate at the second extension 15 of the base 10, which improves the heat exchange efficiency of the base 10 and facilitates the preferential cooling of the water contained in the first water storage tank 12. The lowest position of the first hemispherical groove 121 protrudes from the second side of the first body 11, so that the cold air passing through the at least one through hole 16 first begins to cool the lowest position of the first hemispherical groove 121 to control the first hemispherical groove 121 The water in the groove 121 cools and freezes from bottom to top, and finally forms transparent ice.

It should be noted that the focus of the present invention is to control the water contained in the ice making mold 100 to freeze in a single direction. In this embodiment, the direction of water freezing is from bottom to top, but it is not limited to this. In other embodiments of the present invention, depending on the placement position of the ice-making mold, the direction in which the water freezes may be other directions, as long as the water freezes and freezes in one direction.

In addition, in other embodiments of the present invention, after the ice making module 100 completes ice making, the at least one through hole 16 can also be held by the user to separate the base 10 and the upper cover 20 from each other.

The base 10 can be formed by integral molding, such as injection molding, 3D printing, or casting.

As shown in FIGS. 1 and 2, the upper cover 20 includes a second body 21, and a second hemispherical groove 22 recessed from the bottom surface 212 of the second body 21 toward the top surface 211, wherein the second hemispherical groove 22 Used to form the upper half of the spherical groove S (shown in Figure 4). When the second edge 221 of the second hemispherical groove 22 and the first edge 1211 of the first hemispherical groove 121 abut against each other, the first hemispherical groove 12 and the second hemispherical groove 22 form a spherical groove S( As shown in Figure 4). Among them, the top surface 211 is opposite to the bottom surface 212.

The second edge 221 is higher than the bottom surface 212 of the second body 21, and the bottom surface 212 faces the base 10.

An exhaust hole 23 is provided at the highest position of the second hemispherical groove 22, and the exhaust hole 23 connects the second hemispherical groove 22 with the atmosphere outside the top surface 211 of the second body 21. In other words, the exhaust hole 23 is used to connect the spherical groove S with the outside atmosphere, and the excess gas in the spherical groove S is discharged from the outside atmosphere through the exhaust hole 23. The hole diameter of the vent hole 23 is relatively small, about 5 mm.

The upper cover 20 further includes a buckling groove 24, and the buckling groove 24 is arranged around the outer wall 222 of the second hemispherical groove 22, and the outer wall 222 can be regarded as the groove wall of the buckling groove 24. Wherein, the buckling groove 24 is matched with the groove wall of the cylindrical groove 122. When the upper cover 20 and the base 10 are mutually, the groove wall of the cylindrical groove 122 extends into the buckling groove 24. Since the upper cover 20 is made of silicone material, the silicone material has certain elasticity. Therefore, when the wall of the cylindrical groove 122 is buckled with the fastening groove 24, the fastening groove 24 and the wall of the cylindrical groove 122 are closely attached to each other. , The excess air between the upper cover 20 and the base 10 can be squeezed and discharged from the exhaust hole 23.

In addition, the second hemispherical groove 22 is located inside the groove wall of the cylindrical groove 122, and the second hemispherical groove 22 is in close contact with the groove wall of the cylindrical groove 122, so that the second hemispherical groove 22 It is in a relatively sealed space with the first hemispherical groove 121. When the water contained in the first hemispherical groove 121 and the second hemispherical groove 22 is cooled, the air dissolved in the water gradually escapes from the first hemispherical groove 121 toward the second hemispherical groove 22, It is discharged from the exhaust hole 23 at the bottom of the second hemispherical groove 22 of the upper cover 20.

In addition, corresponding to the buckling groove 24, the top of the groove wall of the cylindrical groove 122 is also provided with a guiding inclined surface 1221, and the guiding shoe upper 1221 makes the buckling of the groove wall of the cylindrical groove 122 and the buckling groove 24 smoother.

As shown in FIG. 2, the thickness of the lowest position of the first hemispherical groove 121 is smaller than the thickness of the highest position of the second hemispherical groove 22. Moreover, since the thermal conductivity of the base 10 in the ice-making mold 100 is greater than that of the upper cover 20, it may be better when the thickness of the lowest position of the first hemispherical groove 121 is smaller than the thickness of the highest position of the second hemispherical groove 22 Controls the direction in which water freezes during ice making.

3 is a schematic diagram of the ice-making mold of the present invention after being fastened; FIG. 4 is a schematic cross-sectional view of the ice-making mold in FIG. 3.

The buckling of the ice making mold 100 of the present invention will be described in detail below with reference to FIGS. 3 and 4.

As shown in FIGS. 3 and 4, the ice making mold 100 is buckled to buckle the upper cover 20 on the base 10, wherein the wall of the cylindrical groove 122 of the first water storage tank 12 of the base 10 is inserted into the upper cover 20 In the buckling groove 24, at this time, the groove wall of the cylindrical groove 122 is in close contact with the buckling groove 24, and the outer wall 222 of the second hemispherical groove 22 is in close contact with the inner side of the groove wall of the cylindrical groove 122 , So that the spherical groove S formed by the first hemispherical groove 121 and the second hemispherical groove 22 is located in a relatively sealed space. The inside of the spherical groove S communicates with the outside through the exhaust hole 23 in the upper cover 20. In addition, the lower part of the second body 21 of the upper cover 20 is locked into the accommodating space between the outer side of the groove wall of the cylindrical groove 122 and the inner side of the first extension portion 13, and the upper cover 20 is stably buckled on the base 10.

When the ice-making mold 100 prepares spherical transparent ice, it is placed in a freezing environment, and the cold is passed through at least one through hole 16 in the second extension portion 15 of the first body 11 of the base 10 and the first hemispherical groove 121 The bottom (lowest position) performs heat exchange. Since the bottom (lowest position) of the first hemispherical groove 121 has a small thickness and high thermal conductivity, it is preferentially cooled by cooling. However, the thermal conductivity of the upper cover 20 is low, and the bottom thickness of the second hemispherical groove 22 in the second body 21 of the upper cover 20 is large. Therefore, it is not easy to exchange heat with the cold in the freezing environment. When the water in the lower part of the first hemispherical groove 121 is cooled and frozen, the cold will gradually transfer from the first hemispherical groove 121 to the second hemispherical groove 22, so that the ice gradually forms from the bottom to the top. The air dissolved in the water is squeezed toward the upper part of the water and discharged from the vent hole 23 to make spherical transparent ice with a high degree of permeability.

Step S4, freezing the ice making mold, and the water in the spherical groove gradually freezes from the first hemispherical groove toward the second hemispherical groove to form a transparent ice ball;

Wherein, the volume of water entering the spherical groove accounts for 90% of the volume of the spherical groove, and the ice-making mold 100 is as described above.

In addition, the ice making method further includes step S5, opening the base 10 and the upper cover 20, and taking out the transparent ice ball. Wherein, the user holds at least one through hole 16 on the second extension 15 on the base 10 with one hand, and the user grasps the non-slip pattern 25 on the outer surface of the upper cover 20 with the other hand, rotates in the opposite direction and/or The base 10 and the upper cover 20 are stretched to separate them from each other, and the transparent ice ball is taken out.

In addition, in step S3, the upper cover of the ice-making mold is fastened to the base. Since the first water storage tank 12 has been filled with water in advance, when the outer wall 222 of the second hemispherical groove 22 is attached to the cylindrical groove 122 The inner side of the groove wall slides until the second edge 221 and the first edge 1211 abut against each other. At this time, there may be a small amount of water in the first water storage tank 12 overflowing from the overflow opening 123 at the top of the cylindrical groove 122. It flows along the outer surface of the groove wall of the cylindrical groove to the first side of the first body 11 and is discharged through the drain hole 14.
