[0002] Transparent spherical ice cubes are known to be popular for use in bourbon, Scotch, whisky, craft cocktails, soft drinks, and other beverages. Transparent spherical ice cubes are essential for these drinks because they melt slowly, have a large surface area, and are visually appealing. While there is also an ice ball maker disclosed in Chinese utility model patent CN219494478U, which includes a water meter, a drive bracket, and within the drive bracket sequentially arranged an evaporator lower bracket, an evaporator, an evaporator lower cover, an evaporator front cover, and an evaporator support; the evaporator lower bracket and the evaporator lower cover are interconnected to form a closed cavity; the evaporator lower cover has a receiving groove containing a lower hemispherical mold with its open end protruding outwards from the evaporator lower cover; the lower hemispherical mold and the evaporator lower cover are sealed together; the evaporator is installed between the evaporator lower bracket and the evaporator lower cover and fitted onto the outer wall of the lower hemispherical mold; the drive bracket is equipped with... The ice hockey maker has a drive mechanism that allows the upper hemispherical mold on the evaporator support to engage or disengage with the corresponding lower hemispherical mold. However, existing ice hockey makers are quite complex, increasing manufacturing difficulty and costs. Furthermore, the ice-making process is time-consuming. While ice hockey makers primarily supply commercial entertainment venues such as homes and bars, requiring the production of larger quantities of ice hockeys, their complex and bulky structure, coupled with their high price, prevents them from meeting the demand for ice hockey makers in home settings. The long ice-making time significantly limits the expansion of their application scenarios, necessitating improvements. Utility Model Content

[0019] (III) The technical effects to be achieved Compared with the prior art, the beneficial effects of this utility model are: Firstly, this utility model includes an ice-making box, a spherical ice mold and a water injection device on the ice-making box. The water injection device is connected to the spherical ice mold, and the spherical ice mold is equipped with a cooling device and an ice-removing device. Its design is more reasonable, its structure is simple, and it is easy to manufacture, thereby reducing the cost of manufacturing. At the same time, it greatly reduces the ice-making time, saves time, and has high ice-making efficiency, meeting the needs of households and businesses for ice-making hockey.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0037] Example 1: See Figures 1 to 10 An ice hockey maker includes an ice-making box 1, a spherical ice mold 2 mounted on the ice-making box 1, and a water injection device 3. The water injection device 3 is connected to the spherical ice mold 2, facilitating water injection. The spherical ice mold 2 is equipped with a cooling device 4 and an ice removal device 5. The cooling device 4 facilitates cooling and ice making on the spherical ice mold 2, while the ice removal device 5 melts and removes ice from the spherical ice mold 2, making it easy to remove the ice hockey. Its design is more rational, its structure is simple, and it is easy to manufacture, thus reducing production costs and significantly shortening ice-making time, saving time and better meeting user needs. It also includes a controller, which can be set at a suitable location in the ice hockey maker according to actual needs. The controller is connected to the spherical ice mold 2, the water injection device 3, the cooling device 4, and the ice removal device 5, respectively controlling the driving operation of the spherical ice mold 2, the water injection action of the water injection device 3, the cooling operation of the cooling device 4, and the ice removal operation of the ice removal device 5.

[0038] Example 2: This can be explained based on Example 1, such as... Figures 1 to 10As shown, the spherical ice mold 2 includes a lower fixing frame 21 mounted on the ice-making box 1. A lower hemispherical mold 22 is mounted in the lower fixing frame 21. An ice-removing device 5 is mounted on the lower hemispherical mold 22 in the lower fixing frame 21. The lower hemispherical mold 22 is connected to the water injection device 3. Rotating connecting pieces 23 are mounted on both ends of the lower fixing frame 21. A rotating shaft 24 is mounted between the two rotating connecting pieces 23. Two fixing brackets 25 are mounted on the rotating shaft 24. The two fixing brackets 25 are connected to each other through an upper fixing frame 26. An upper hemispherical mold 27 is mounted in the upper fixing frame 26. The upper fixing frame 26 rests on the lower fixing frame 21. When the upper hemisphere mold 27 and the lower hemisphere mold 22 are connected to the frame 21, they form an ice-making mold. This facilitates the entry of water into the lower hemisphere mold 22. A cooling device 4 is provided on the upper hemisphere mold 27. When the upper hemisphere mold 27 and the lower hemisphere mold 22 form an ice-making mold, after water is injected into the ice-making mold by the water injection device 3, the water injected into the ice-making mold can be cooled and iced by the cooling device 4. After an ice ball is formed in the ice-making mold, the ice-removing device 5 is used for operation. The rotating shaft 24 is connected to the drive source 6. In use, the drive source 6 drives the rotation of the rotating shaft 24, which in turn drives the two fixed frames 25 to rotate. When the two fixed frames 25 rotate to the side of the lower fixed frame 21, the upper fixed frame 26 between the two fixed frames 25 falls onto the lower fixed frame 21. At this time, the upper hemispherical mold 27 and the lower hemispherical mold 22 form an ice-making mold. The drive source 6 then stops rotating the rotating shaft 24. Water is then injected into the ice-making mold through the water injection device 3. Next, the cooling device 4 cools the water injected into the ice-making mold to make ice. After an ice ball is formed in the ice-making mold, the ice-removing device 5 melts and removes the ice from the ice-making mold. Finally, the drive source 6 rotates in the opposite direction again, which causes the rotating shaft 24 to drive the two fixed frames 25 to rotate in the opposite direction, which in turn causes the upper fixed frame 26 to rotate in the opposite direction. The upper fixed frame 26 separates from the lower fixed frame 21, and the user can then remove the ice ball. In this embodiment, the rotating connecting piece 23 uses a hexagonal shaft, which is more conducive to implementation.In this embodiment, the lower hemispherical mold 22 moves relative to the upper hemispherical mold 27, realizing the opening and closing of the lower hemispherical mold 22 and the upper hemispherical mold 27; here, the movement of the lower hemispherical mold 22 relative to the upper hemispherical mold 27 is rotation; that is, the rotation shaft 24 is driven by the drive source 6, and then the rotation shaft 24 drives the two fixed frames 25 to rotate, so that the lower hemispherical mold 22 rotates toward the upper hemispherical mold 27 until the lower hemispherical mold 22 and the upper hemispherical mold 27 are closed, and the mold cavity of the lower hemispherical mold 22 and the corresponding mold cavity of the upper hemispherical mold 27 are closed to form a spherical mold cavity; the rotation shaft is driven by the drive source 6. The rotation of shaft 24 causes the two fixed frames 25 to rotate. After the reverse drive is performed, the lower hemispherical mold 22 rotates away from the upper hemispherical mold 27, and the lower hemispherical mold 22 separates from the upper hemispherical mold 27. The mold cavity of the upper hemispherical mold 27 separates from the corresponding mold cavity of the lower hemispherical mold 22. At this time, the spherical mold cavity is opened until the angle between the lower hemispherical mold 22 and the upper hemispherical mold 27 reaches a predetermined angle (for example, the range of the predetermined angle is set to 130° to 180°) as the lower hemispherical mold 22 rotates, so that the ice puck located in the cavity of the lower hemispherical mold 22 can fall out of the cavity of the lower hemispherical mold 22.

[0039] like Figures 1 to 10As further illustrated, to ensure the motor stops operating on the rotating shaft 24 when the upper hemispherical mold 27 and the lower hemispherical mold 22 form the ice-making mold, at least one of the fixing brackets 25 and the upper fixing frame 26 is equipped with a limit switch 28. When the limit switch 28 on the fixing bracket 25 touches the rotating shaft 24, and the limit switch 28 on the upper fixing frame 26 touches the lower fixing frame 21, a stop signal is given to the motor, making it more convenient to use. The outer wall of the lower fixing frame 21 is provided with a protrusion for contacting the limit switch 28 on the upper fixing frame 26, which facilitates the activation of the limit switch 28 on the upper fixing frame 26. The drive source 6, which drives the rotating shaft 24, is connected to a controller. The drive source 6 is configured to apply either a positive or negative driving force; for example, the drive source 6 here is a drive motor. The rotating shaft 24 is in transmission cooperation with both the lower hemispherical mold 22 and the drive source 6. The rotating shaft 24 is configured to receive the driving force applied by the drive source 6 and, under the drive of the drive source 6, to drive the lower hemispherical mold 22 to perform an opening and closing action relative to the upper hemispherical mold 27. A limit switch 28 is connected to the controller, and the limit switch 23 is configured to detect the rotational travel of the lower hemispherical mold 22 during the opening and closing process relative to the upper hemispherical mold 27. For example, when the drive source applies a positive driving force, the rotating shaft 24 rotates accordingly to drive the lower fixed frame 21 and the lower mold on the lower fixed frame 21 to rotate towards the upper hemispherical mold 27; conversely, when the drive source 6 applies a negative driving force, the rotating shaft 24 rotates accordingly to drive the lower mold 12 to rotate away from the upper hemispherical mold 27.

[0040] like Figures 1 to 10 As shown, the lower hemispherical mold 22 includes a fixing seat 221 disposed in the lower fixing frame 21. The fixing seat 221 is provided with a plurality of lower hemispherical seats 222. Each lower hemispherical seat 222 is provided with a water inlet hole 223 for communication with the water injection device 3. The upper hemispherical mold 27 includes a mounting seat 271. The mounting seat 271 is provided with a plurality of upper hemispherical seats 272. The upper hemispherical seats 272 and the lower hemispherical seats 222 are in a one-to-one correspondence. When the upper hemispherical seats 272 and the lower hemispherical seats 222 are aligned, a spherical body is formed. This is beneficial for making multiple ice balls at one time. In this embodiment, there are four upper hemispherical seats 272 and four lower hemispherical seats 222, so four ice balls can be made at one time. The number of upper hemispherical seats 272 and lower hemispherical seats 222 can be determined according to the actual situation. To further explain, the lower fixed frame 21 is provided with a fixing groove 211 for installing the lower hemispherical seat 222. This is more conducive to the convenient installation of the lower hemispherical mold 22. It should also be noted that each fixing groove 211 is provided with a through hole 212. This design is reasonable and easy to implement.

[0041] likeFigures 1 to 10 As shown, to further illustrate, an inlet water bend pipe 261 is provided on the upper fixed frame 26, and an inlet water straight pipe 262 is connected to the inlet water bend pipe 261. Both the other end of the inlet water bend pipe 261 and the inlet water straight pipe 262 are connected to an external water tank. This is beneficial for cooling the surrounding area through water circulation.

[0042] Example 3: This can be explained based on Example 2, such as... Figures 1 to 10 As shown, the water injection device 3 includes a water pump 31 mounted on the ice-making box 1 and a water trough mounted on the lower fixed frame 21. A cover plate 32 is provided on the lower end face of the water trough, and a water injection pipe 33 is provided on the end face of the lower fixed frame 21. The water injection pipe 33 is connected to the water trough, and the water pump 31 is connected to the water injection pipe 33 through a connecting pipe 34. A water injection hole 35 is provided on the lower fixed frame 21 at the position of the water trough, and the water injection hole 35 corresponds to the lower hemispherical mold 22. In this way, the water pump 31 can inject water from the ice-making box 1 into the lower hemispherical mold 22 through the water pump 31 and the connecting pipe 34, which is beneficial for making ice balls. In this embodiment, the water injection device 3 is configured to perform water injection work under control to inject water into the spherical mold cavity formed by the spherical ice mold 2. The water injection device 3 performs the aforementioned water injection work under the control of the controller. The water pump 31 is connected to the controller and is configured to pump the water required for ice making.

[0043] like Figures 1 to 10 As shown, to further illustrate, the ice container 1 is equipped with a water temperature probe 11 and a float 12. This is beneficial for detecting the temperature and water content of the water in the ice container 1. The water temperature probe 11 can be connected to a controller, which can be set at a suitable position in the ice ball ice maker according to actual needs.

[0044] Example 4: This can be described based on Example 2 or Example 3, such as... Figures 1 to 10As shown, the de-icing device 5 includes a heating wire 51 disposed on the lower fixed frame 21 for heating the lower hemispherical mold 22. The heating wire 51 extends through the lower fixed frame 21 and is connected to a heat source. The heat source is connected to a controller and is configured to execute a heating mode under the control of the controller to generate heat to be supplied to the aforementioned coil. This heat is transferred to each upper mold cavity of the upper mold via the coil. The heating wire 51 is located inside the lower fixed frame 21 and below the bottom of the lower hemispherical mold 22. The heating wire 51 is configured to perform a heating operation to transfer heat to the bottom of each lower hemispherical mold 22. In this embodiment, a 12V heating wire is used for the heating wire 51, which is more conducive to heating and aiding in de-icing. In this embodiment, the de-icing device 5 is configured to perform de-icing under control to transfer heat to the cooled and bonded area between the ice ball that has solidified after cooling and the inner wall of the spherical ice mold 2, melting the ice at the cooled and bonded area. Specifically, the de-icing device 5 performs the aforementioned de-icing operation after being controlled by the controller.

[0045] Example 5: This can be described based on Example 2, Example 3, or Example 4, such as... Figure 11 As shown, in this embodiment, the cooling device 4 is configured to perform a cooling operation under control to cool the water injected into the spherical cavity of the spherical ice mold 2, causing it to freeze into ice after cooling. The cooling device 4 performs the aforementioned cooling operation under the control of a controller. The cooling device 4 includes an ice-making coil disposed on the upper hemispherical mold 27, connected to a controller (which can be externally configured), and a cooling source connected to the controller. This cooling source is configured to execute a cooling operation mode under the control of the controller to generate outwardly output cold energy. The ice-making coil is disposed on and die-cast integrally with the upper hemispherical mold 27. The ice-making coil is configured to receive the cold energy from the cooling source and transfer it to the upper hemispherical seat 272 within the upper hemispherical mold 27. For example, the ice-making coil is disposed on the upper hemispherical mold 27 in a coiled manner. The ice-making coil here preferably covers the top wall of the upper mold cavity of all the upper hemispherical seats 272. This can accelerate the transfer efficiency of cold energy in the ice-making coil to the upper mold cavity and accelerate the cooling efficiency of the water in the spherical mold cavity.

[0046] As a means of implementing the aforementioned cooling and heating sources, in this embodiment, the ice-making mechanism for the ice puck is used in an ice maker, such as... ​As shown, the ice maker also includes a motor-driven compressor 7 and a solenoid valve. The motor-driven compressor 7 is connected to a controller and is configured to, under the control of the controller, execute either a cooling mode to generate the aforementioned cold energy or a heating mode to generate the aforementioned heat energy. When the motor-driven compressor 7 switches to cooling mode, it becomes the cooling source; when it switches to heating mode, it becomes the heating source. The solenoid valve is connected to the controller and is configured to open under control to cooperate with the motor-driven compressor 7 in switching between cooling and heating modes.

[0047] The ice-making process of the ice hockey ice maker in this embodiment is described below: When ice balls need to be made, the drive source 6 drives the rotating shaft 24 to rotate under the control of the controller. The lower fixed frame 21 rotates towards the upper fixed frame 26 as the rotating shaft 24 rotates, until the upper hemispherical seat 272 on the upper hemispherical mold 27 and the lower hemispherical seat 222 on the lower hemispherical mold 22 are closed in correspondence, and the upper hemispherical mold 27 and the lower hemispherical mold 22 cooperate to close to form a spherical mold cavity. The water pump 31 pumps water from the water storage chamber of the ice box 1 to make ice and delivers the pumped water through the connecting pipe 34 to the water channel at the bottom of the lower fixed frame 21. Then, the water in the water channel is injected into the lower hemispherical seat 222 of the corresponding lower hemispherical mold 22 through the water injection holes 35 on the base. The solenoid valve is opened under the control of the controller, and the motor drives the compressor 7 to work in the refrigeration mode. The cold energy generated in the refrigeration mode is transferred to the upper hemispherical seats 272 on the upper hemispherical mold 27 through the ice-making coil. As water is continuously injected from the bottom of the lower hemispherical mold 22 into the lower hemispherical seat 222 and cold energy is continuously injected into the spherical mold cavity through the upper hemispherical mold 27, the water injected into the spherical mold cavity is continuously cooled and condensed, eventually forming an ice ball that matches the inner side of the spherical mold cavity. After an ice ball is formed inside the spherical mold cavity, the solenoid valve opens in reverse under the control of the controller, and the motor drives the compressor 7 to switch to the heating mode. The heat generated in the heating mode is transferred to each of the upper hemispherical seats 272 on the upper hemispherical mold 27 through the ice-making coil. At the same time, the heating wire 51 located at the bottom of the lower hemispherical mold 22 also performs heating work. The heat generated by the heating wire 51 is also transferred to the bottom of the lower hemispherical mold 22. In this way, the top of the ice ball will be heated by the heat transferred by the motor-driven compressor 7 in the heating mode, and the bottom of the ice ball will be heated by the heat generated by the heating wire. As a result, the part of the ice ball top that is bonded to the inner wall of each of the upper hemispherical seats 272 of the upper hemispherical mold 27 will be fused by heat, and the part of the ice ball bottom that is bonded to the inner wall of the lower hemispherical seat 222 of the lower hemispherical mold 22 will also be fused by heat. Thus, the ice ball will no longer have any parts bonded to the upper hemispherical seat 272 or the lower hemispherical seat 222 due to water cooling. Then, under the control of the controller, the drive source 6 drives the rotating shaft 24 to rotate in the opposite direction. The lower fixed frame 21 gradually moves away from the upper fixed frame 26. The ice puck is located in the lower hemispherical seat 222 and the lower hemispherical seat 222 rotates away from the upper hemispherical seat 272. When the lower hemispherical seat 222 rotates to the preset rotation stroke (reaching the aforementioned predetermined angle), a large space is formed between the lower hemispherical seat 222 and the upper hemispherical seat 272. The ice puck falls out of the lower hemispherical seat 222 due to the tilt of the lower hemispherical seat 222 during rotation and falls into the ice puck collection chamber of the ice puck maker, thus obtaining the required ice puck.

[0048] In this invention, the rotating shaft 24 of the ice hockey maker is connected to a drive source 6. A controlled motor drives the compressor 7 and a solenoid valve. A heating wire 51 is installed at the bottom of the lower hemispherical seat 222 in the lower hemispherical mold 22. The solenoid valve controls the switching between cooling and heating modes of the motor-driven compressor 7. This ensures that the cooling energy generated by the motor-driven compressor 7 in cooling mode can be transmitted from the mold cavity of the upper hemispherical mold 27 to the mold cavity of the ice-making mold via the ice-making coil, reducing the temperature inside the ice-making mold cavity to cool and condense the water already injected into the mold cavity into ice. The heat generated by the motor-driven compressor 7 switching to heating mode is then transferred to the top of each upper hemispherical seat 272 on the upper hemispherical mold 27 via the ice-making coil, while the heat generated by the heating wire 51 is transferred to the bottom of the lower hemispherical seat 222 in the lower hemispherical mold 22. In this way, not only is the water injected into the mold cavity of the ice-making mold cooled into ice, but also the bidirectional heating of the top and bottom of the mold cavity of the ice-making mold ensures that the bond between the prepared ice ball and the inner wall of the mold cavity of the ice-making mold caused by water cooling melts, which facilitates the demolding of the ice ball from the mold cavity of the ice-making mold and improves the integrity and aesthetics of the ice ball.
