Description

Technical Field

[0001] The utility model relates to the technical field of ice-making devices for beverages, in particular to a mobile container for ice-making. Background Art

[0002] Ice trays are commonly used ice-making tools in daily life, generally comprising a box body and an ice tray mold. The ice tray mold is used to be placed in a freezing device after being filled with water, so as to freeze the water in the ice tray mold into ice cubes.

[0003] Existing ice cube trays are mostly made of solid ice cubes when they are made and dispensed. When dispensing ice, multiple ice cube trays made of all-silicone are squeezed by twisting and kneading to make the ice cubes come out of the ice cube trays, and then poured out after the ice cubes are demolded. When ice cubes are used as cold drinks, multiple solid ice cubes tend to pile up in the cup. When drinking through a straw, the straw is often blocked by the piled ice cubes and is not easy to insert into the bottom of the cup. In addition, solid ice cubes in the cup will make noise when the cup is shaken; due to the accumulation of ice cubes, the entire cup is not evenly cooled from top to bottom.

[0004] Chinese patent CN219415336U discloses an ice box, including a box body, a box cover and at least one ice grid board, wherein a plurality of ice grids are arranged on the ice grid board. When removing ice, the ice grid board is turned 180 degrees and the opening of the ice grid is placed downward into the box body, and the two ends of the ice grid board are placed on the left and right protrusions respectively, and then the box cover is buckled on the ice grid board, and the protrusions are pressed on the ice grid board. The box cover is pressed, and the force is focused on the protrusions. The protrusions distributed diagonally act on the ice grid board. The left rear corner of the ice grid board is twisted and deformed downward along the upper surface of the left protrusion under the action of one of the protrusions, and the right front corner of the ice grid board is twisted and deformed downward along the upper surface of the right protrusion under the action of another protrusion. The ice grid board is twisted and deformed to make the ice cubes in each ice grid fall out. The advantages of this ice box are that a large number of ice cubes are produced at one time and it is easy to remove ice. The disadvantage is that the ice cubes produced are solid ice cubes.

[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] Example 1

[0060] See also Figure 1 The mold assembly 200 for making bushing-type ice cubes of the present invention includes a plurality of mold units 100 , and preferably the number of the mold units 100 is three.

[0061] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a mold unit 100 for making bushing-type ice cubes comprises an outer wall 1, an inner wall 2 and a bottom wall 3. The outer wall 1 is arranged in an annular shape to define the outer peripheral shape of the bushing-type ice cube; the inner wall 2 is arranged in an internal column shape to define the through-hole shape of the bushing-type ice cube; the bottom wall 3 is arranged between the outer wall 1 and the bottom of the inner wall 2 to define the bottom shape of the bushing-type ice cube; the outer wall 1, the inner wall 2 and the bottom wall 3 enclose an annular space 9 of the mold unit, and the upper part of the annular space 9 has an opening 4 for adding ice-making water.

[0062] When making ice, water, beverages or other ice-making water is injected into the annular space 9 of the mold unit 100 through the opening 4 for storage, and then the mold unit 100 is placed in a refrigeration device such as a refrigerator or freezer to make ice at low temperature. The ice-making water stored in the annular space 9 of the mold unit 100 condenses under the action of low temperature. When ice is required, the mold unit 100 is taken out of the refrigeration device, and the mold unit 100 is squeezed and twisted to deform the mold unit 100, so that a gap is generated between the ice cubes in the annular space 9 and the outer wall 1, the inner wall 2 and the bottom wall 3, so that the ice cubes are released from the opening 4 of the annular space 9 of the mold unit 100 to obtain bushing-type ice cubes, which have upper and lower through holes.

[0063] In order to make the formed bushing-shaped ice cubes easy to be released from the annular space 9 of the mold unit 100, a draft angle is provided on the outer wall 1 and the inner wall 2 forming the annular space 9. Specifically, the outer wall 1 and the inner wall 2 of the annular space 9 are both inclined so that the cross-sectional area of ​​the annular space 9 gradually decreases from the opening 4 of the annular space 9 to the bottom wall 3. Figure 5 In the figure, a is the distance between the outer wall 1 and the inner wall 2 at the upper part of the annular space 9, b is the distance between the outer wall 1 and the inner wall 2 at the lower part of the annular space 9, and a>b.

[0064] In this embodiment, the inner and outer contour lines 91 of the cross-section of the annular space 9 of the mold unit 100 are circular, specifically, the outer contour line 911 is circular; the inner contour line 912 corresponding to the outer contour line 911 is circular, and the diameter of the outer contour line 911 is larger than the diameter of the inner contour line 912, forming a bushing-type mold unit 100.

[0065] When the bushing-type mold unit 100 is defrosted, the annular space 9 of the mold unit 100 is inverted so that the opening 4 of the annular space 9 faces downward and the bottom wall 3 of the mold unit 100 faces upward. Since the outer wall 1 and the inner wall 2 of the annular space 9 have a draft angle, the outer wall 1 and the inner wall 2 will not block the side walls of the bushing-type ice cubes formed by condensation of ice-making water in the annular space 9. The bushing-type ice cubes can be smoothly removed from the annular space 9 of the mold unit 100, thus making defrosting convenient.

[0066] In this embodiment, a water tray 5 is arranged at the top of the outer wall 1 of the mold unit 100. The water tray 5 is substantially parallel to the bottom wall 3, and its function is to prevent the top of the outer wall 1 from being deformed. A top plate 6 is arranged at the top of the inner wall 2, so that the internal column forms a hollow structure with an opening downward, and its function is to prevent the top of the inner wall 2 from being deformed; inside the hollow structure, a plurality of reinforcing ribs 7 are also arranged. The reinforcing ribs 7 are integrally formed with the inner wall 2 and the top plate 6, and each of the reinforcing ribs 7 is composed of radial ribs 71 and busbar ribs 72. The radial ribs 71 are extended along the back of the top plate 6, and the busbar ribs 72 are connected to the radial ribs 71 and extend along the back of the inner wall 2. Specifically, the busbar ribs 72 are arranged along the busbar CC direction of the inner wall 2, and the provided reinforcing ribs 7 are used to resist the internal column deformation. A reinforcing ring 8 is also arranged at the junction of the back of the water tray 5 and the outer wall 1, and its advantage is that it can increase the anti-deformation ability at the outer edge of the opening 4 of the mold unit 100.

[0067] The outer wall 1, inner wall 2, bottom wall 3, water tray 5, top plate 6 and reinforcing rib 7 of the annular space 9 of the mold unit 100 of this embodiment are integrally formed and made of silica gel material. Since silica gel material is insoluble in water, non-toxic and tasteless, has stable chemical properties, and does not react chemically with any substance except strong alkali and hydrofluoric acid, has good thermal stability, stable chemical properties, and high mechanical strength, it can be used as a good material for the mold unit of the bushing type ice cube.

[0068] like Figure 7 , Figure 8 and Fig. 9 As shown, the three mold units 100 in the mold combination 200 of the present embodiment are respectively set as a small mold unit 20, a medium mold unit 30 and a large mold unit 40 according to their sizes, and are arranged in a straight line in sequence, and the axis XX of the small mold unit 20, the axis YY of the medium mold unit 30, and the axis ZZ of the large mold unit 40 are basically parallel, and the water trays 5 of the mold units 100 are connected as a whole in the same horizontal plane. Among them, the maximum dimension c of the bottom of the annular space 9 of the small mold unit 20 is greater than the minimum dimension d of the top of the annular space 9 of the medium mold unit 30; and the maximum dimension e of the bottom of the annular space 9 of the medium mold unit 30 is greater than the minimum dimension f of the top of the annular space 9 of the large mold unit 40, that is, c>d, e>f. Since the minimum dimensions of the annular spaces 9 of the three mold units 100 exist in the above situation, small, medium and large bushing-type ice cubes with different radial dimensions can be produced, such as Fig.10 As shown, bushing-type ice cubes of small size g1, medium size g2 and large size g3.

[0069] On the front of the integrated water tray 5, a bridge water trough 51 is provided between adjacent mold units 100 to connect the annular spaces 9, which is conducive to the mutual supplementation of ice-making water in adjacent annular spaces 9. When ice-making water is added to the annular space 9 of the mold assembly 200, the ice-making water in the annular spaces 9 of the three mold units 100 is kept at the same height. Therefore, when making ice cubes, the height dimensions of the bushing-type ice cubes made by the annular spaces 9 of the three mold units 100 are basically consistent. Around the front of the water tray 5, an annular convex edge 52 extending upward and downward is provided to increase the anti-deformation ability of the outer edge of the water tray 5 of the mold assembly.

[0070] In the mold assembly 200 of this embodiment, the upper surface of the top plate 6 of the mold unit 100 is provided with an identification block 60 for identifying small, medium and large sizes. On the small mold unit 20, the medium mold unit 30 and the large mold unit 40 of the mold assembly 200, the identification block 60 is used to distinguish the types of bushing-type ice cubes, which is very convenient and not easy to confuse. The identification block 60 can be a number, a letter or a pattern, etc., as long as it is convenient to distinguish the small, medium and large sizes of the prepared bushing-type ice cubes.

[0071] To prepare bushing-type ice cubes, ice-making water such as water or beverages is added into the annular space 9 of the small mold unit 20, the medium mold unit 30 and the large mold unit 40, and then the mold assembly 200 is placed in a refrigeration device such as a refrigerator or a freezer to make ice at low temperature. The ice-making water in the annular space 9 of the mold assembly 200 condenses under the action of low temperature. When ice is required, the mold assembly 200 is taken out of the refrigeration device, and the opening 4 of the mold unit 100 is downward, and the mold unit 100 is squeezed and twisted, so that the annular space 9 of the mold unit 100 is deformed, and a gap is generated between the ice cube in the annular space 9 and the outer wall 1, the inner wall 2 and the bottom wall 3, so that the ice cube escapes from the annular space 9 of the mold assembly 200, and small, medium and large bushing-type ice cubes are obtained respectively, and the bushing-type ice cube is an ice cube with a through-hole shape.

[0072] The advantages of this embodiment are that the bushing-shaped ice cubes of small size g1, medium size g2 and large size g3 prepared by the mold assembly 200 are stacked and placed in the Stanley cup from the bottom to the mouth of the cup (see Fig.10 ), the Stanley Cup is a deep-mouthed beverage cup with a handle. The cross-sectional area of ​​the container gradually increases from the bottom to the mouth of the cup. Ice cubes are usually added to the cup container and the drink is sucked through a straw. In the Stanley Cup, the outer periphery of the sleeve-type ice cubes matches the inner wall of the cup, which is beneficial to reduce collision noise. The through-hole structure of the sleeve-type ice cubes facilitates the straw to be directly inserted into the bottom of the cup. The sleeve-type ice cubes are stacked in the cup, so that the cup body is evenly covered with ice, the melting speed of the ice cubes is reduced, and the cold drink can be kept for a long time.

[0073] Example 2

[0074] See also Fig.11 The main difference between the second embodiment and the first embodiment is that the arrangement of the three mold units 100 of the mold assembly 200 for making bushing-type ice cubes is different. In this embodiment, the small mold unit 20, the medium mold unit 30 and the large mold unit 40 are arranged around the central axis AA of the mold assembly 200, and the periphery of the water tray 5 of the mold unit 100 is an arc-shaped edge structure.

[0075] Example 3

[0076] See also Fig.12 The main difference between the third embodiment and the second embodiment is that the mold assembly 200 for making sleeve-type ice cubes also includes an upper cover 70, which is sealed on the top of the water tray 5 of the mold unit 100. The top of the mold unit 100 is covered by the upper cover 70 to prevent foreign matter from falling into the annular space 9 of the mold assembly 200.

[0077] Example 4

[0078] See also Fig.13 and Fig.14 The main difference between this embodiment and the first embodiment is that the inner and outer contour lines 91 of the cross section of the annular space 9 of the mold unit 100 are polygonal. Specifically, the outer contour 911 and the inner contour 912 of the cross section of the annular space 9 of the mold unit 100 are both polygonal structures, preferably dodecagonal.

[0079] In addition, the main difference between this embodiment and the second embodiment is that an overflow hole 53 is provided on the water tray 5 of the mold unit 100. The overflow hole 53 is used to discharge the accumulated liquid on the water tray 5 of the mold unit 100.

[0080] It should be noted that the inner and outer contour lines 91 of the cross section of the annular space 9 are of a dodecagonal structure, or other polygonal structures. The cross sections of the outer and inner walls of the bushing-shaped ice cube produced thereby are of a polygonal structure.

[0081] Example 5

[0082] See also Fig.15 The main difference between this embodiment and the fourth embodiment is that the mold assembly 200 for making bushing-type ice cubes further includes an upper cover 70, which completely covers the top of the mold unit 100 to prevent foreign matter from falling into the annular space 9 of the mold assembly 200. In addition, a flexible connecting belt 701 is provided between the edge of the upper cover 70 and the edge of the water tray 5 to facilitate the opening and closing of the upper cover 70 relative to the water tray 5.

[0083] It should be noted that in the mold assembly 200 for making sleeve-type ice cubes of the present application, the inner and outer contour lines 91 of the cross-section of the annular space 9 of the mold unit 100, in addition to being set to a circle or a polygon, can also be selected into other shapes, such as an arc shape, an elliptical shape, etc., and can also be designed into a cartoon shape, so that the cross-section of the finished ice cube forms a shaped ice cube with through holes of different shapes, so as to improve the aesthetics of the produced sleeve-type ice cube.

[0084] Example 6

[0085] See also Fig.16 , Fig.17 , Fig.18 and Fig.19 A mold box for making bushing-type ice cubes includes a box body 301 and a box cover 302. The box body 301 is used to store the above-mentioned mold assembly 200, and the box cover 302 is used to seal the mold assembly 200 inside the box body 301 to prevent foreign matter from falling into the mold box.

[0086] Among them, the box body 301 is mainly composed of a horizontal box bottom 301a and an annular side wall 301b, which are connected to form a watertight container. The mold assembly 200 is arranged in the container. The horizontal box bottom 301a of the box body 301 is used to place the bottom wall 3 of the mold unit 100 of the mold assembly 200, that is, the bottom wall 3 of the mold unit 100 of the mold assembly 200 is abutted against the horizontal box bottom 301a, and the shape of the mouth of the box body 301 is consistent with the shape of the water tray 5 connected thereto. Therefore, the mold assembly 200 is adapted to the container of the box body 301 as a whole.

[0087] The plane where the mouth of the box body 301 is located is substantially parallel to the plane where the integral water tray 5 is located, so as to prevent the mold assembly 200 from tilting in the box body 301 and causing the ice-making liquid in the annular space 9 of the mold unit 100 to flow out.

[0088] like Fig.19 , Fig. 20 and Fig.21 As shown, at the top end of the annular side wall 301b of the box body 301, an annular step edge 301c is provided inwardly, and the annular edge of the box cover 302 extends downward in two layers to form an annular snap-in groove 302a. The annular snap-in groove 302a of the box cover 302 can be snapped on both sides of the annular step edge 301c of the box body 301 to achieve a joint snap connection between the box cover 302 and the box body 301.

[0089] On the outer side of the annular step edge 301c of the box body 301, there are outer clamping strips 301d protruding outwardly distributed intermittently in the circumference, and on the inner side of the outer wall of the annular clamping groove 302a of the box cover 302, there are inner clamping strips 302b protruding inwardly distributed intermittently in the circumference. The circumferentially distributed positions of the outer clamping strips 301d and the inner clamping strips 302b are consistent. When the joint between the box cover 302 and the box body 301 is clamped, the box cover 302 and the box body 301 are more tightly combined.

[0090] like Fig. 20 As shown, at the lower end of the outer wall of the downward extending annular snap-fit ​​groove 302a on one short side of the box cover 302, a lift plate 302c similar to a hat brim shape is extended outward. When the box cover 302 is opened from the box body 301, it is only necessary to apply force upward to the lift plate 302c. Therefore, the lift plate 302c provided on the box cover 302 makes it easy to open the box cover 302.
