Description

Technical Field

[0001] This invention relates to the field of ice-making equipment technology, and in particular to a high-quality ice-making mold. Background Technology

[0002] Ice makers, as a simple additive for cold drinks and alcoholic beverages, are easy to make, have a beautiful crystal appearance, enhance the taste, and improve the quality of life, making them increasingly popular in the market.

[0003] Currently, traditional ice makers on the market use simple metal chambers or ice molds made of flexible materials. Ice made with metal chambers is prone to cracking or uneven in shape, resulting in rough, unattractive ice. Meanwhile, conventional all-silicone flexible molds produce ice slowly. Summary of the Invention

[0004] In order to address the technical deficiencies mentioned in the background section, the purpose of this invention is to provide a high-quality ice-making mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-quality ice-making mold, comprising: The first mold has an opening on one side, and a first elastic pad is embedded on the inner wall of the first mold cavity. The second mold is provided in at least one set. The second mold has openings on both sides. One second mold cavity is sealed to the first mold cavity to form a closed ice-making cavity. A second elastic pad is provided in each of the two second mold cavities. The third mold has an open third mold cavity on the side facing the second mold, and the third mold cavity and another second mold cavity form a closed ice-making cavity; a third elastic pad is embedded on the inner wall of the third mold cavity; An evaporator tube is provided, and at least one set of the evaporator tube is provided. One end of the evaporator tube is fitted onto the outer periphery of one ice-making chamber, and the other end of the evaporator tube is fitted onto the outer periphery of another ice-making chamber. Each ice-making chamber is equipped with a set of water inlet and outlet devices to allow water to flow within the ice-making chamber.

[0006] By adopting the above technical solution, a first elastic pad is set in the first mold cavity, a second elastic pad is set in the second mold cavity, and a third elastic pad is set in the inner wall of the third mold cavity. The elastic deformation of the elastic pads releases the stress generated by the volume increase when water freezes, providing more space for ice block formation and resulting in higher quality ice blocks. The first, second, and third elastic pads do not completely fill the ice-making chamber, and the evaporator tube is wrapped around the outer periphery of the ice-making chamber, resulting in higher refrigerant cold transfer efficiency and a wider and more uniform coverage area, significantly improving ice-making efficiency. The water inlet and outlet device can drive the water flow in the ice-making chamber to remove gas from the water, thus making the ice blocks more transparent. Furthermore, the two ice-making chambers can produce two ice blocks simultaneously each time, requiring only three molds, making assembly convenient, resulting in high ice-making efficiency and lower cost.

[0007] Furthermore, the evaporator tube is configured with a spiral structure, with both ends of the evaporator tube located outside the second mold, and the portion between the two ends of the evaporator tube disposed inside the second mold, spirally wound around the outer periphery of the two second mold cavities. The evaporator tube is integrally formed with the second mold, improving the refrigeration efficiency and ice-making efficiency.

[0008] Furthermore, the second mold cavity is configured as a hemispherical structure, and the side of the evaporator tube located in the second mold cavity is configured as a frustum-shaped structure. The spiral winding area of ​​the evaporator tube on the outer periphery of the second elastic pad is minimized, so that the distance between the evaporator tube and the second mold cavity remains consistent, resulting in more uniform ice formation and cost savings.

[0009] Furthermore, the water inlet and outlet device includes multiple sets of water inlet pipes and multiple sets of water outlet pipes, with each second mold cavity corresponding to one set of water inlet pipes and one set of water outlet pipes. The water inlet pipe is located on one side of the second mold, with one end passing through the second mold and communicating with the corresponding second mold cavity. The water outlet pipe is located above the second mold, with the other end passing through the second mold and communicating with the corresponding second mold cavity. The water inlet and outlet pipes allow water to flow within the corresponding ice-making cavity, carrying out any gas in the water and resulting in more transparent ice.

[0010] Furthermore, the second mold is provided with a mounting groove connecting the two second mold cavities, and a second elastic pad is sealed and installed at both ends of the mounting groove. One end of the second elastic pad is provided with an enlarged end, which is located in the corresponding second mold cavity to seal the end of the mounting groove. The other end of the second elastic pad is interference-fitted with the inner wall of the mounting groove, which facilitates installation and removal. It can also utilize the elastic deformation factor of the second elastic pad to release the stress generated by the volume increase when water freezes, resulting in higher quality ice blocks.

[0011] Furthermore, the first mold is provided with a through-hole groove at both ends, one end of which communicates with the first mold cavity. A protruding engaging portion is provided on the inner wall of the groove, and a corresponding groove is provided on the outer periphery of the first elastic pad. One end of the first elastic pad is sealed to the end of the groove located in the first mold cavity. The engaging portion is engaged within the groove, facilitating easy installation and removal and improving installation efficiency. Moreover, this improves the stability of the first elastic pad and limits its deformation.

[0012] Furthermore, a gap is provided between the other end of the first elastic element and the inner wall of the slot to provide space for deformation of the first elastic element, thereby improving the deformation effect and ensuring the ice-making quality.

[0013] Furthermore, the cross-sectional area of ​​the slots is set to be the same, and the cross-sectional area of ​​the other end of the first elastic pad gradually decreases along the direction away from the groove. The other end of the first elastic pad is hollow, which facilitates installation and makes the deformable end of the first elastic pad more flexible.

[0014] Furthermore, a mold-closing elastic ring is provided between the first mold and the second mold, and between the second mold and the third mold. The mold-closing elastic ring is interference-fitted to the side of the second mold, and the side of the mold-closing elastic ring is connected to the ice-making cavity. This can improve the waterproof effect and release the stress generated by the increase in volume when water freezes by utilizing the elastic deformation factor of the mold-closing elastic ring, resulting in higher quality ice blocks.

[0015] Furthermore, a fixing groove is provided on the opening side of both the first mold cavity and the third mold cavity, and the mold-closing elastic ring is engaged in the corresponding fixing groove. The area of ​​the side of the mold-closing elastic ring that contacts the fixing groove is larger than the area of ​​the side of the mold-closing elastic ring that contacts the second mold, which facilitates installation, allows for the application of extrusion force towards the second mold side, and improves the sealing effect.

[0016] In summary, the beneficial effects of the present invention are as follows: The high-quality ice-making mold of this invention features a first elastic pad in the first mold cavity, a second elastic pad in the second mold cavity, and a third elastic pad on the inner wall of the third mold cavity. The elastic deformation of these pads releases the stress caused by the volume increase during water freezing, providing more space for ice formation and resulting in higher quality ice. The first, second, and third elastic pads do not completely cover the ice-making chamber, and the evaporator tube is wound around the outer periphery of the ice-making chamber, resulting in higher refrigerant cold transfer efficiency and a wider, more uniform coverage area, significantly improving ice-making efficiency. The water inlet / outlet device can drive the water flow within the ice-making chamber to remove gas from the water, thus making the ice more transparent. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-5 The embodiments of the present invention will be described in further detail below.

[0027] A high-quality ice-making mold 1, such as Figure 1 , Figure 2 As shown, it includes a first mold 2, a second mold 3, a third mold 4, an evaporation tube 5, and a water inlet / outlet device. The second mold 3 is located between the first mold 2 and the third mold 4. The first mold 2 has an open first cavity 21 on one side, and a first elastic pad 22 is embedded in the inner wall of the first cavity 21. At least one set of second molds 3 is provided, with open second cavities 31 on both sides of the second mold 3. One second cavity 31 is sealed to the first cavity 21 to form a closed ice-making cavity. A second elastic pad 32 is provided in each of the two second cavities 31. Multiple sets of second molds 3 can be arranged adjacently. The third mold 4 has an open third cavity 41 on the side facing the second mold 3. The third cavity 41 and another second cavity 31 enclose a closed ice-making cavity. A third elastic pad 42 is embedded in the inner wall of the third cavity 41. At least one set of evaporation tubes 5 is provided, with one end of the evaporation tube 5 fitted onto the outer periphery of one ice-making cavity and the other end of the evaporation tube 5 fitted onto the outer periphery of another ice-making cavity. Each ice-making chamber is equipped with a set of water inlet and outlet devices to allow the water inside the ice-making chamber to flow.

[0028] A first elastic pad 22 is placed in the first mold cavity 21, a second elastic pad 32 is placed in the second mold cavity 31, and a third elastic pad 42 is placed in the inner wall of the third mold cavity 41. The elastic deformation of these pads releases the stress caused by the volume increase during water freezing, providing more space for ice block formation and resulting in higher quality ice blocks. The first elastic pad 22, second elastic pad 32, and third elastic pad 42 do not completely cover the ice-making chamber, and the evaporator pipe 5 is wrapped around the outer periphery of the ice-making chamber, resulting in higher refrigerant cold transfer efficiency and a wider and more uniform coverage area, significantly improving ice-making efficiency. The water inlet / outlet device can drive the water flow within the ice-making chamber to remove gas from the water, making the ice blocks more transparent. Furthermore, the two ice-making chambers can produce two ice blocks simultaneously each time, requiring only three molds, making assembly convenient, resulting in high ice-making efficiency and lower cost.

[0029] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 The first mold 2, the second mold 3, and the third mold 4 are all designed with a square structure. Of course, other circular structures are also possible, depending on the requirements, and are not limited here. The first mold 2 has a through-hole groove 24, one end of which is connected to the first mold cavity 21. A protruding engaging part 23 is provided on the inner wall of the groove 24, and a corresponding groove 26 is provided on the outer periphery of the first elastic pad 22. One end of the first elastic pad 22 is sealed to the end of the groove 24 located in the first mold cavity 21, and the engaging part 23 is engaged within the groove 26, facilitating easy installation and removal and improving installation efficiency. Furthermore, it can improve the stability of the first elastic pad 22 and limit its deformation.

[0030] A gap is provided between the other end of the first elastic element and the inner wall of the slot 24 to provide space for deformation of the first elastic element, thereby improving the deformation effect and ensuring the ice-making quality.

[0031] The cross-sectional area of ​​the slots 24 is set to be the same. The cross-sectional area of ​​the other end of the first elastic pad 22 gradually decreases along the direction away from the groove 26. The other end of the first elastic pad 22 is hollow, which makes it easy to install and makes the deformable end of the first elastic pad 22 more flexible.

[0032] The slot 24 is cylindrical, and the engaging part 23 can be a protruding annular structure or multiple spaced block structures. The end face of the first elastic ring located at one end of the first mold cavity 21 is circular and convex. One end of the hollow portion inside the first elastic ring is connected to the outside, and the other end is located between the groove 26 and the end face of the first elastic ring, facilitating the installation of the first elastic ring.

[0033] In this embodiment, please refer to Figure 3 , Figure 4 , Figure 5 A mold-closing elastic ring 7 is provided between the first mold 2 and the second mold 3, and between the second mold 3 and the third mold 4. The mold-closing elastic ring 7 is interference-fitted with the side of the second mold 3, and the side of the mold-closing elastic ring 7 is connected to the ice-making cavity. This can improve the waterproof effect and release the stress generated by the increase in volume when water freezes by utilizing the elastic deformation factor of the mold-closing elastic ring 7, resulting in higher quality ice blocks.

[0034] Both the first mold cavity 21 and the third mold cavity 41 have a fixing groove 25 on their opening sides, and the mold closing elastic ring 7 is engaged in the corresponding fixing groove 25. The area of ​​the side of the mold closing elastic ring 7 that contacts the fixing groove 25 is larger than the area of ​​the side of the mold closing elastic ring 7 that contacts the second mold 3, which facilitates installation and allows for the application of extrusion pressure towards the second mold 3 side, thereby improving the sealing effect.

[0035] Specifically, the fixing groove 25 is open on both sides facing the first mold cavity 21 and the second mold 3, and the depth of the fixing groove 25 gradually decreases along the direction away from the first mold cavity 21. The outer periphery of the mold closing elastic ring 7 is set as an annular stepped structure, and the side of the mold closing elastic ring 7 that contacts the second mold 3 is set vertically and horizontally to improve flatness and sealing effect.

[0036] The first elastic pad 22, the second elastic pad 32, the third elastic pad 42 inside the ice-making cavity and the mold-closing elastic ring 7 can be designed with a reasonable structural size based on the volume change data of water and ice. The local structural design of the elastic body does not affect the ice-making efficiency. Due to the elastic deformation factor, the stress generated by the volume increase when water freezes into ice can be eliminated, and the ice blocks produced do not crack and have a smooth and round surface.

[0037] In this embodiment, the first mold 2 and the third mold 4 have the same structure, the first elastic pad 22 and the third elastic pad 42 have the same structure, and the specific structure of the third mold 4 can be referred to the above-mentioned related content.

[0038] In this embodiment, please refer to Figure 3 , Figure 4 The second mold 3 is provided with a mounting groove 33 connecting the two second mold cavities 31. A second elastic pad 32 is sealed and installed at both ends of the mounting groove 33. One end of the second elastic pad 32 is provided with an enlarged end, which is located in the corresponding second mold cavity 31 to seal the end of the mounting groove 33. The other end of the second elastic pad 32 is interference-fitted with the inner wall of the mounting groove 33, which is convenient for installation and removal. It can also use the elastic deformation factor of the second elastic pad 32 to release the stress generated by the volume increase when water freezes, resulting in higher quality ice blocks.

[0039] The first mold cavity 21, the second mold cavity 31, and the third mold cavity 41 all have the same structure and can be set to various structures such as spherical or square, depending on the actual shape of the ice block to be made. No limitation is made here.

[0040] The first mold cavity 21, the second mold cavity 31, and the third mold cavity 41 are all set as hemispherical structures. The side of the evaporation tube 5 located on the second mold cavity 31 is set as a frustum structure. The spiral winding area of ​​the evaporation tube 5 on the outer periphery of the second elastic pad 32 is minimized, so that the distance between the evaporation tube 5 and the second mold cavity 31 is kept consistent, making the ice forming more uniform and saving costs.

[0041] In this embodiment, please refer to Figure 3 , Figure 4 The evaporator tube 5 is configured with a spiral structure. Both ends of the evaporator tube 5 are located outside the second mold 3, while the portion between the two ends of the evaporator tube 5 is located inside the second mold 3 and spirally wound around the outer periphery of the two second mold cavities 31. The evaporator tube 5 and the second mold 3 are integrally formed, which improves the efficiency of refrigeration and ice making.

[0042] In this embodiment, please refer to Figure 3 , Figure 4 The water inlet and outlet device includes multiple sets of water inlet pipes 61 and multiple sets of water outlet pipes 62. Each second mold cavity 31 is equipped with a set of water inlet pipes 61 and a set of water outlet pipes 62. The water inlet pipes 61 are located on one side of the second mold 3, with one end passing through the second mold 3 and communicating with the corresponding second mold cavity 31. The water outlet pipes 62 are located above the second mold 3, with the other end passing through the second mold 3 and communicating with the corresponding second mold cavity 31. The water inlet pipes 61 and water outlet pipes 62 allow the water in the corresponding ice-making cavity to flow, thereby removing gas from the water and making the ice blocks more transparent.

[0043] The water inlet pipe 61 can be placed below the second mold 3 to further promote the flow of water and improve the quality of ice making.

[0044] Specifically, the inlet pipe 61 and outlet pipe 62 are integrated with the heating structure, which is not shown in the drawing. After ice making is completed, both inlet pipe 61 and outlet pipe 62 are heated to melt the ice blockage inside. Once the ice inside inlet pipe 61 and outlet pipe 62 has melted, the next ice-making cycle can begin. During de-icing, inlet pipe 61 and outlet pipe 62 can be heated to improve de-icing efficiency, serving multiple functions, saving costs and equipment space, and resulting in a more compact structure.

[0045] During ice making, water enters the ice-making chamber through the inlet pipe 61 at the bottom or any position, and overflows through the outlet pipe 62 at the top, creating a continuous water flow that removes gas from the water, resulting in highly transparent ice. The evaporation pipe 5 is placed directly inside the second mold 3, forming a single unit. When working, the evaporation pipe 5 effectively transfers cold energy to the ice-making chamber, significantly improving ice-making efficiency. The first elastic pad 22 or third elastic pad 42, the second elastic pad 32, and the mold-closing elastic ring 7 on both sides of the ice-making chamber release the stress caused by the expansion of water volume during ice formation, preventing the ice from cracking. After ice making, both the inlet pipe 61 and the outlet pipe 62 can heat and melt any ice blockages in the water pipes, improving de-icing efficiency. After de-icing, the next ice-making cycle begins. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
