Description

Technical Field

[0001] The utility model relates to the field of ice making devices, in particular to an ice tray for making ice cones. Background Art

[0002] An ice box is an ice-making module that is placed in a freezing chamber of a refrigerator after being filled with water so as to freeze the water in the ice-making chamber into ice. The ice box is widely used in daily life.

[0003] The existing ice making boxes on the market usually consist of a box body, an ice mold placed in the box body, and a cover body. When taking ice from an ice making box of this structure, the ice mold placed in the box body needs to be taken out first, then the ice mold is turned over and placed upside down in the box body, and finally the cover body is closed on the box body and the ice is taken out by pressing the cover body downward. The multiple steps of taking ice make it time-consuming and inconvenient for users to use. For example, an ice cube box with authorization number CN 215490477 U is convenient for making and taking ice. The patent structure includes a box body 1, a cover body 2, and an ice cube box 3 arranged inside the box body 1. A vertically upward rib assembly is arranged on the inner wall of the box body 1, and a notch assembly used in conjunction with the rib assembly is arranged on the outer edge of the ice cube body 3. An ice taking plate 4 for convenient ice taking is clamped on the inner side surface of the cover body 2, and an icicle knocking column 5 is integrally arranged on the ice taking plate 4. When making ice, water is put into the ice-making chamber, and the ice tray body filled with water is placed into the box body through the notch, and the lid is closed. After the ice cubes are made, the lid is opened, the ice tray body is turned upside down, and the ice tray body is fixed by the convex strips and the slots, and then the lid is closed, and the lid is pressed left and right, so that the knocking icicles exert a certain vibration force on the ice-making chamber, so that the ice cubes fall into the box body, and the ice is taken out. Although the patent is much more convenient to take out than ordinary ice cubes and ice trays. But it is still an ice mold for making ice cubes. When taking ice, the patent still needs to invert the ice tray and take out the ice cubes one by one. The efficiency of taking ice is very low. Moreover, the ice cubes made by the ice mold are scattered in the cup when in use, and then soaked with coffee, cola, beer and other drinks. Due to the small size of the ice cubes, they are easy to melt quickly, and the melted and smaller ice cubes are easy to be eaten by children by mistake.

[0004] The patent with the authorization number CN 219889825 U discloses a manual ice-making module, including a housing 1, an ice-making assembly 2 and a water supply assembly 3. An ice-making space is formed inside the housing 1. The ice-making assembly 2 includes an ice tray 21, and the ice-making assembly 2 is arranged on the upper part of the ice-making space. The water supply assembly 3 is arranged above the ice-making assembly 2, and the water supply assembly 3 includes a detachable water box 31, a cover plug 32 and a water injection member 33. Water is injected into the ice tray 21 in the water box 31 through a water injection port 311 on the bottom plate of the water box 31. Although the ice tray is convenient for water injection during ice making, it is still an ice mold for making ice cubes. When taking ice in the patent, it is still necessary to invert the ice tray and take out the ice cubes one by one. The efficiency of taking ice is very low. Moreover, the ice cubes made by the ice mold are scattered in the cup when in use, and then soaked with coffee, cola, beer and other beverages. Due to the small size of the ice cubes, it is easy to melt quickly, and the melted and smaller ice cubes are easy to be eaten by children by mistake. Therefore, it is necessary to develop an ice tray that can be quickly demolded and prevent children from accidentally eating ice, so as to promote the innovative development of ice tray products.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings 1-11 and the specific implementation method: The utility model relates to an ice tray for preparing one-piece ice cubes that can be quickly demoulded, and is mainly used to prepare one-piece ice cubes. The ice cube can be placed in an ice cup or an ordinary cup when in use, and then a drink is poured into the cup. The ice cube can increase the contact area with the drink fluid, thereby achieving the effect of uniformly cooling the drink fluid and improving the cooling effect.

[0034] The ice tray comprises a base 1, an upper cover 2 and an ice mold core rod 3. The base 1 and the upper cover 2 are preferably made of silicone material in a rectangular shape. The base 1 and the upper cover 2 are snap-fitted together to form a complete shell. The base 1 and the upper cover 2 completely accommodate the ice mold core rod 3 therein, thereby ensuring the hygiene of the ice tube when making it.

[0035] The base 1 is provided with a lower arc-shaped cavity 11 extending along its length direction for accommodating the ice mold core rod 3, and the front and rear side walls of the lower arc-shaped cavity 11 are respectively provided with a first lower arc-shaped step 12 and a second lower arc-shaped step 13, and the two ends of the ice mold core rod 3 are respectively placed on the two steps. A lower annular connecting surface 14 is formed on the end surface of the cavity wall of the lower arc-shaped cavity 11.

[0036] An upper arc-shaped cavity 21 extending along its length direction for accommodating the ice mold core rod 3 is provided on the upper cover 2, and a first upper arc-shaped step 22 and a second upper arc-shaped step 23 are respectively provided on the front and rear side walls of the upper arc-shaped cavity 21, and these two steps are pressed on the two ends of the ice mold core rod 3. An upper annular connecting surface 24 is formed on the end surface of the cavity wall of the lower arc cavity 21; the lower arc cavity is communicated with the upper arc cavity and spliced ​​into a circular accommodating cavity, the first lower arc step 12 is connected with the first upper arc step 22 to form a first annular step, a first circular accommodating space is formed in the first annular step, the second lower arc step 13 is connected with the second upper arc step 23 to form a second annular step, and a second circular accommodating space is formed in the second annular step; an ice mold core rod 3 completely accommodated in the base and the upper cover is placed in the circular accommodating cavity, the two ends of the ice mold core rod 3 are respectively provided with a first core rod fixed end 31 and a second core rod fixed end 32, the first core rod fixed end 31 and the second core rod fixed end 32 are respectively correspondingly clamped on the first annular step and the second annular step, a cylindrical ice forming cavity 4 is formed between the ice mold core rod 3 and the circular accommodating cavity wall, a water inlet 5 connected with the cylindrical ice forming cavity 4 is provided on the upper cover 2, and the lower annular connecting surface 14 and the upper annular connecting surface 24 are connected and fixed when the base 1 and the upper cover 2 are buckled.

[0037] When assembling this product, first align the first core rod fixed end 31 and the second core rod fixed end 32 at both ends of the ice mold core rod 3 with the first lower arc step 12 and the second lower arc step 13 of the base 1, and then put the ice mold core rod 3 into the lower arc cavity 11. At this time, the ice mold core rod 3 and the lower arc cavity 11 form a semi-cylindrical gap. Then align the first upper arc step 22 and the second upper arc step 23 of the upper cover with the first core rod fixed end 31 and the second core rod fixed end 32 of the ice mold core rod 3, and snap the upper cover 2 onto the base 1. At this time, a tube ice forming cavity 4 is formed between the ice mold core rod 3 and the circular accommodating cavity wall. The product is assembled and ready for making tube ice.

[0038] When it is necessary to make ice cubes, clean water is added from the water inlet 5 to fill the entire ice cube forming cavity 4, and then the entire ice cube tray is placed in a refrigerator for freezing. After a certain period of freezing, the water in the ice cube forming cavity 4 freezes into a hollow cylindrical shape with two ends open.

[0039] A demoulding structure is provided on the base 1 and the upper cover 2 to facilitate separation of the two. The demoulding structure includes a lower demoulding handle 15 and an upper demoulding handle 25.

The lower demoulding handle 15 and the upper demoulding handle 25 are arranged opposite to each other. When it is necessary to demould and take out the ice, the lower demoulding handle 15 and the upper demoulding handle 25 are pulled apart by both hands. At this time, the lower demoulding handle 15 and the upper demoulding handle 25 drive the upper cover to separate from the base, so that the upper cover is separated from the base, and then the ice mold core rod 3 with the prepared ice cube tube is removed from the base, and then the ice cube tube is removed from the ice mold core rod 3. In this way, the ice cube tube can be made quickly by using the ice tray of this structure. The ice tray of the present invention avoids the need to invert the ice tray and take out the ice cubes piece by piece as in the prior art. Instead, the upper cover can be directly removed without inverting the ice tray, and the whole block of ice can be conveniently taken out from the ice mold core rod 3. Not only is the ice taking efficiency very high, but the ice making is clean and hygienic. When the whole block of ice is put into the ice cup or ordinary cup, due to its slow melting and large volume, it can not only achieve a long-term iced drink, but also prevent children from accidentally eating it, and has a high safety performance.

[0041] The inner diameter of the circular accommodating cavity gradually increases from the second annular step toward the first annular step, and the outer diameter of the ice mold core rod 3 gradually increases from the second annular step toward the first annular step. The outer wall of the ice mold core rod 3 is tapered, so that the ice tube forming cavity 4 is tapered. The tapered ice tube forming cavity 4 can improve the circumferential bearing capacity of the produced ice tube and improve the firmness of the ice tube.

[0042] In order to further improve the direct sealing effect between the base and the upper cover, avoid water leakage in the cavity and improve hygiene problems, a multi-layer sealing structure is provided between the base and the upper cover, and the multi-layer sealing structure includes a first vertical annular clamping platform 17 and a second vertical annular clamping platform 18 arranged on the lower annular connecting surface 14 of the base, the outer diameter of the first vertical annular clamping platform 17 is larger than the outer diameter of the second vertical annular clamping platform 18, and an annular slot 19 is formed between the first vertical annular clamping platform 17 and the second vertical annular clamping platform 18.

The multi-layer sealing structure can prevent bacteria from entering the molding cavity and prevent water added into the molding cavity from leaking out.

[0043] An annular groove 101 having a diameter larger than that of the first annular step is provided on the first annular step, and an annular positioning boss 301 having an outer diameter larger than that of the first core rod fixed end 31 and capable of being inserted into the annular groove 101 is provided on the first core rod fixed end 31 of the ice mold core rod 3. The above structure can prevent the ice mold core rod 3 from moving back and forth in the base, so as to achieve a stable ice making effect.

[0044] In order to improve the pulling effect of the handle and achieve better demoulding efficiency, the upper surface of the lower demoulding handle 15 is flush with the upper surface of the outer shape fitting surface 10 on the base, and the upper surface of the upper demoulding handle 25 is flush with the upper surface of the outer annular fitting surface 10 on the upper cover. The lower demoulding handle 15 and the upper demoulding handle 25 are tightly attached together when the base and the upper cover are buckled. An array of integrally formed reinforcing ribs 201 are arranged on the other side of the lower demoulding handle 15 and the upper demoulding handle 25. The arrangement of the reinforcing ribs 201 can minimize the size of the handle without reducing the pulling effect of the handle.

The height of the bowl-shaped water adding funnel 401 is higher than the upper cover, and the bottom of the bowl-shaped water adding funnel 401 is connected to the water adding port 5. The end of the bowl-shaped water adding funnel 401 forms an expansion port 402 that is larger than the water adding port 5.

[0046] The ice mold core rod 3 can be solid or hollow. When the ice mold core rod 3 is hollow, it is a cylindrical core rod 34 with an opening at one end and a bottom at the other end. A circular cover 35 is provided at the opening of the cylindrical core rod, and the fixed shaft 33 is provided on the circular cover 35.

[0047] In order to save materials, save energy consumption, and improve the production efficiency of the product, a rectangular annular frame 100 is provided at the bottom of the base 1, a conical convex wall 102 is provided inside the annular frame 100, the other side wall of the conical convex wall 102 forms the lower arc cavity, and reinforcing plates 103 connecting the annular frame 100 and the conical convex wall 102 are arranged vertically and horizontally alternately between the annular frame 100 and the conical convex wall 102.
