DETAILED DESCRIPTION OF EMBODIMENTS

The present disclosure will be described in detail below with reference to the accompanying drawings and embodiments. Each example is provided by way of an explanation of the present disclosure rather than limiting of the present disclosure. In fact, those skilled in the art will recognize that modifications and variations can be made in the present disclosure without departing from the scope or spirit of the invention. For example, features shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is intended that the present disclosure includes such modifications and variations as come within the scope of the appended claims and their equivalents.

As shown in FIG. 1 to FIG. 17, an ice ball making box is provided with a first ice-making layer 5, a second ice-making layer 6, a third ice-making layer 7, an ice storage layer 8 and an ice ball mold. The ice ball mold includes first ice mold bodies 1, second ice mold bodies 2, third ice mold bodies 3 and press-demolding parts 4.

Application principle: see FIG. 9 for the ice block molding process, water is filled into ice ball mold cavities 100 of the ice ball mold from the first ice-making layer 5; after water is frozen completely in the ice ball mold cavities 100, take down the third ice-making layer 7, place the first ice-making layer 5 and the second ice-making layer 6 together on the ice storage layer 8; see FIG. 16 and FIG. 17, while taking down the third ice mold bodies 3 on the third ice-making layer 7, the ice ball mold cavities 100 are directly communicated with storage spaces of the ice storage layer 8, at the time, the first ice-making layer 5 is pressed so that the press-demolding parts 4 press the first ice mold bodies 1 to enable ice balls to fall into the ice storage layer 8 from the ice ball mold cavities 100.

Specifically, the first ice mold body 1 of the mold includes a water inlet passage 10 and a press wall 18 wrapping the top of an ice ball; the water inlet passage 10 and the press wall 18 are made of a flexible material that can return to its original state after being pressed to deform, and the press wall 18 is provided with an overflow hole 11. In the technical solution, the shape and structure of the first ice mold body 1 can refer to FIG. 1 to FIG. 6, the first ice mold body 1 acts on an upper half portion of an ice ball body, especially the top, the water inlet passage 10 allows water to be filled to the ice ball mold cavity 100, and the press wall 18 can be externally pressed to force an ice ball in the ice ball mold cavity 100 to get away from the ice ball mold; the edge of the lower surface of the press wall 18 is provided with a circle of assembly step 19 to be assembled with the second ice mold body 2; the water inlet passage 10 and the press wall 18 can be made of a flexible material such as silica gel or rubber and can deform and return to its original state; the overflow hole 11 allows the excess water that is filled to spill out of the ice ball mold cavity 100, the overflow hole 11, formed in the press wall 18, maintains a certain height difference with the bottommost end of the water inlet passage 10 to prevent excess ice blocks from going into the water inlet passage 10 due to volume expansion in the water freezing process; the overflow hole 11 is an elliptic hole with a short axis pointing to the water inlet passage 10; and compared with a perfect circular overflow hole, the overflow efficiency of the elliptic overflow hole 11 is higher under the same hole area.

Specifically, an ice ball freezing and hanging portion 12 is formed on the sidewall of an inner circumference of the water inlet passage 10 to block part of the water inlet passage 10. The ice ball freezing and hanging portion 12 is shaped like a baffle or a step, located at the bottommost end of the water inlet passage 10. The ice ball freezing and hanging portion 12 at least blocks more than half of the water inlet passage 10. The ice ball freezing and hanging portion 12 is provided with a freezing and hanging eave 120 which is straight, arc-shaped or serrated. In the technical solution, the ice ball freezing and hanging portion 12 is formed as some water flows into the water inlet passage 10 to form an ice pillar in the water freezing and expansion process, and the ice pillar can be hung to the first ice mold body 1 through the ice ball freezing and hanging portion 12, so the whole ice ball can not fall off after taking down the third ice mold body 3 on the third ice-making layer 7 and can be completely and smoothly placed on the ice storage layer 8 along with the first ice-making layer 5 and the second ice-making layer 6, thereby releasing the ice ball more stably and preventing the ice ball from dropping and being contaminated as it is moved; the shape and the arrangement mode of the ice ball freezing and hanging portion 12 can refer to FIG. 1 and FIG. 2, the ice ball freezing and hanging portion 12, shaped like a baffle or a step, blocks the water inlet passage 10, water flows over the baffle-like or step-like ice ball freezing and hanging portion 12 and then can be frozen and hung securely, and in the demolding process, the straight, arc-shaped or serrated freezing and hanging eave 120 can more easily break off an unnecessary ice pillar body formed as the ice ball gets frozen; and various embodiments of the freezing and hanging eave 120 can refer to FIG. 4, FIG. 5 and FIG. 6 in the drawings.

Specifically, the sidewall of the water inlet passage 10 is an upper thin and lower thick structure. In the technical solution, the upper thin and lower thick water inlet passage 10 can refer to FIG. 1. The sidewall of an upper portion of a passage opening is thin, and the sidewall of a lower portion of the passage opening is thick. When the unnecessary ice pillar needs to be broken off by bending, the water inlet passage 10 can return to its original state more easily. Thus, it is a structure that is more in line with the application principle of the ice ball mold.

Specifically, ice balls in the ice ball mold are released through the press-demolding parts 4. As the press-demolding parts 4 moves toward the ice ball mold cavities 100, the press-demolding portions 40 at the bottom ends of the press-demolding parts abuts against the upper surfaces of the press walls 18 of the first ice mold bodies 1 and can squeeze the first ice mold bodies 1 to deform to release the ice balls. In the technical solution, the press-demolding portion 40 is a portion abutting against the press wall 18, including an abutting surface and an abutting point. This can refer to a circular surface in FIG. 11. See FIG. 11, the press-demolding part 4 is cylindrical and can be sleeved on an outer peripheral side of the water inlet passage 10.

Specifically, a press-bending portion 41 is formed on the press-demolding part 4. When the press-demolding part 4 is pressed to move downwards, the press-bending portion 41 at least partially touches the water inlet passage 10 to bend the water inlet passage 10, and the press-bending portion 41 is in an upper wide and lower narrow structure; in the technical solution, the press-bending portion 41 squeezes the water inlet passage 10 to enable an ice pillar body therein to get broken off at the ice ball freezing and hanging portion 12 as the press-demolding part 4 is pressed to move downwards to perform demolding, thereby enabling the demolding process to be easier and more effort-saving and the steps to be more simplified; the shape of the press-bending portion 41 can refer to FIG. 11, a wide portion of the press-bending portion 41 has a higher pressure to the water inlet passage 10, and the upper wide and lower narrow structure can be in conjunction with the upper thin and lower thick structure of the sidewall of the water inlet passage 10 to enable the press-demolding part to be pressed more easily with less effort.

Specifically, the first ice-making layer 5 is provided with a water filling trough 50, a water filling hole 51 is formed at the position corresponding to the water inlet passage 10 of each first ice mold body in the water filling trough 50, and a guide slope 52 is formed around the periphery of the water filling hole 51, inclined toward the water filling hole 51; the water filling trough 50 is divided into a plurality of water filling lattices 54 by ribs 53, and the surfaces of the water filling lattices 54 are inclined toward the water filling holes 51. In the technical solution, the water filling trough 50, the water filling holes 51, the guide slopes 52 and the water filling lattices 54 have the effect of allowing water to be accurately and rapidly filled into the ice ball mold cavities 100. It's worth noting that when the inclined angle of the guide slopes 52 is the same as that of the water filling lattices 54, and both may be visually in the same plane. However, it should be still noted that the existence of the guide slopes 52 and the water filling lattices 54 inclined toward the water filling holes 51 falls within the scope of protection of the technical solution.

Specifically, a lid 56 corresponding to the water filling trough 50 is arranged on the first ice-making layer 5, and the lid 56 is fixedly mounted on the first ice-making layer 5 in a limiting buckled or articulated mode. In the technical solution, the lid 56 is used for covering the water filling trough 50 to keep the water filled into the ice ball mold cavities 100 clean.

Specifically, an inspection window 55 is formed in the first ice-making layer 5, an overflow hole 11 is formed in the first ice mold body 1, and the overflow holes 11 are all formed on one side close to the inspection window 55. In the technical solution, the inspection window 55 is used to inspect whether the ice ball mold cavities 100 are filled with water and water spills out of the overflow holes 11. The inspection window 55 may be structurally a hollowed-out window hole which can be a transparent glass plate; correspondingly, to see the positions of the overflow holes 11 visually and easily through the inspection window 55, the overflow holes 11 are formed on one side, close to the inspection window 55, of the first ice mold bodies 1.

In the technical solution, see FIG. 8, the excess water that is filled into the ice ball mold cavities 100 can be drained through the first drain holes 60 and the second drain holes 70. The first drain hole 60 extends into the second drain hole 70 or the second drain hole 70 extends into the first drain hole 60. To achieve a smoother draining effect, the overflow holes 11 are formed on one side, close to the first drain holes 60 and the second drain holes 70, of the first ice mold bodies 1, thereby allowing the spilled water to more easily flow to the first drain holes 60 and the second drain holes 70.

Specifically, a return rebound structure is arranged between the first ice-making layer 5 and the second ice-making layer 6, including guide posts 57 on the first ice-making layer 5 and positioning tubes 61 on the second ice-making layer 6, and return springs 62 are placed in the positioning tubes 61. In the technical solution, see FIG. 16 and FIG. 17, when the first ice-making layer 5 is pressed to release ice balls, the guide posts 57 of the first ice-making layer 5 rebound and return to its original state through the return springs 62, and therefore, a user can use the ice ball making box more conveniently with less effort.

Specifically, the first ice-making layer 5 and the second ice-making layer 6 are connected and fixed through a buckle connecting structure, including buckles 58 on the sidewall of the first ice-making layer 5 and clamping grooves 63 in the sidewall of the second ice-making layer 6. In the technical solution, the first ice-making layer 5 and the second ice-making layer 6 can be moved simultaneously through the buckle connecting structure.
