[0002] An ice hockey maker is a refrigeration device that cools water through a refrigeration system, causing the water to cool and form ice balls (or spherical ice). The ice hockey maker uses a refrigeration system with an ice-making mechanism to freeze water into ice balls within a product mold (specifically, a spherical cavity). The ice balls obtained using this ice hockey maker are then added to beverages, satisfying people's demand for chilled drinks. Currently, due to the high demand for ice balls in commercial and entertainment venues such as bars, existing ice hockey makers primarily supply these venues.

[0041] Firstly, the ice-making system of this novel ice hockey maker comprises a mold assembly, a drive mechanism, a water injection mechanism, a cooling mechanism, an ice removal mechanism, and a controller. The mold assembly has an upper mold cavity and a lower mold cavity that are driven by the drive mechanism to open and close in cooperation. The upper mold cavity and the corresponding lower mold cavity close together to form a spherical mold cavity. The water injection mechanism injects water into this spherical mold cavity. The cooling mechanism cools the water injected into the spherical mold cavity, causing it to freeze into ice. The ice removal mechanism then transfers heat to the cooled and bonded area between the frozen ice ball and the inner wall of the spherical mold cavity, melting the ice and thus producing the desired ice ball. Therefore, this ice hockey maker is not only simple in structure but also meets the ice-making needs of a home environment.

[0042] Secondly, in this utility model ice hockey maker, the ice removal mechanism prevents the ice hockey from breaking at both ends during demolding, thus improving the ice-making efficiency and yield rate, and enhancing the ice-making experience.

[0043] Finally, the ice-making system of this utility model ice hockey machine employs a controlled motor-driven compressor and solenoid valve, with a heating wire installed at the bottom of the lower mold cavity. The solenoid valve controls the switching between cooling and heating modes of the motor-driven compressor. This ensures that the cooling energy generated by the compressor in cooling mode is transferred from the upper mold cavity to the spherical mold cavity via the coil, lowering the temperature inside the spherical mold cavity to cool and condense the water already injected into it into ice. The heat generated by switching the compressor to heating mode is then transferred to the top of the upper mold cavity via the coil, while the heat generated by the heating wire is transferred to the bottom of the lower mold cavity. This not only achieves the cooling and condensation of the water already injected into the spherical mold cavity, but also ensures the melting of the adhesion between the prepared ice hockey and the inner wall of the spherical mold cavity due to water cooling through bidirectional heating of the top and bottom of the spherical mold cavity. This facilitates the demolding of the ice hockey from the mold cavity and improves the integrity and aesthetics of the ice hockey's appearance. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0056] To facilitate understanding of the embodiments of this utility model, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0057] This embodiment provides an ice hockey maker for manufacturing ice hockey pucks. See also: Figures 1-10 As shown, the ice hockey maker of this embodiment includes an ice-making system, which comprises a mold assembly, a drive mechanism, a water injection mechanism, a cooling mechanism, an ice removal mechanism, and a controller (not shown in the figure). The controller is connected to the drive mechanism, the water injection mechanism, the cooling mechanism, and the ice removal mechanism, respectively controlling the driving operation of the drive mechanism, the water injection action of the water injection mechanism, the cooling operation of the cooling mechanism, and the ice removal operation of the ice removal mechanism. The controller can be set at a suitable location in the ice hockey maker according to actual needs.

[0058] The mold assembly includes an upper mold 11 and a lower mold 12 that open and close together. The upper mold 11 has at least one upper mold cavity 110, and the lower mold 12 has at least one lower mold cavity 120. The upper mold 11 is located above the lower mold 12. The upper mold cavity 110 and the corresponding lower mold cavity 120 close together to form a spherical mold cavity. The shape of the spherical mold cavity (i.e., the inner wall of the spherical mold cavity) is generally spherical. The number of upper mold cavities 110 on the upper mold 11 and the number of lower mold cavities 120 on the lower mold 12 can also be adjusted according to actual needs. For example, the upper mold 11 has four upper mold cavities 110, and correspondingly, the lower mold 12 has four lower mold cavities 120; or, as needed, the upper mold 11 has 1 to 3 upper mold cavities 110, and the lower mold 12 has the same number of lower mold cavities 120 as the upper mold cavities.

[0059] Of course, if the upper mold cavity, lower mold cavity, and other structures (such as the base) need to cooperate to form a complete spherical mold cavity, then when the upper mold cavity adopts a hemispherical mold cavity, the lower mold cavity here cooperates with the other structures (such as the base) to form a hemispherical mold cavity.

[0060] In this embodiment, the drive mechanism is configured to perform a drive operation after being controlled, so as to drive the lower mold 12 of the mold assembly to move relative to the upper mold 11, thereby realizing the opening and closing of the lower mold 12 and the upper mold 11; here, the movement of the lower mold 12 relative to the upper mold 11 is rotation; that is, after the drive mechanism performs the drive operation, it can make the lower mold rotate toward the upper mold until the lower mold and the upper mold are closed, and the lower mold cavity and the corresponding upper mold cavity are closed to form a spherical mold cavity; after the drive mechanism performs the reverse drive operation, the lower mold rotates away from the upper mold, the lower mold and the upper mold separate, the upper mold cavity and the corresponding lower mold cavity separate, and the spherical mold cavity is opened until, with the rotation of the lower mold, the included angle between the lower mold and the upper mold reaches a predetermined angle (for example, the range of the predetermined angle is set to 130° to 180°), so that the ice ball located in the lower mold cavity can be released from the lower mold cavity.

[0061] In this embodiment, the water injection mechanism is configured to perform water injection under control to inject water into the spherical mold cavity formed by the mold assembly; wherein the water injection mechanism performs the aforementioned water injection under the control of the controller.

[0062] In this embodiment, the cooling mechanism is configured to perform a cooling operation under control to cool the water injected into the spherical cavity of the mold assembly, causing it to condense into ice after cooling; wherein the cooling mechanism performs the aforementioned cooling operation under the control of the controller.

[0063] In this embodiment, the de-icing mechanism 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 inside the spherical mold cavity and the inner wall of the spherical mold cavity, thereby melting the ice at the cooled and bonded area. Specifically, the de-icing mechanism performs the aforementioned de-icing operation under the control of a controller.

[0064] In this embodiment, the drive mechanism includes a drive source 21, a rotating shaft 22, and a limit switch 23. The drive source 21 is connected to a controller and is configured to apply a positive or negative driving force. For example, the drive source 21 here is a drive motor. The rotating shaft 22 is in transmission cooperation with both the lower mold 12 and the drive source 21. The rotating shaft 22 is configured to receive the driving force applied by the drive source 21 and, under the drive of the drive source 21, drive the lower mold 12 to perform an opening and closing action relative to the upper mold 11. The limit switch 23 is connected to the controller and is configured to detect the rotational stroke of the lower mold 12 during the opening and closing process relative to the upper mold 11. For example, when the drive source applies a positive driving force, the rotating shaft rotates accordingly to drive the lower mold to rotate towards the upper mold; conversely, when the drive source applies a negative driving force, the rotating shaft rotates accordingly to drive the lower mold 12 to rotate away from the upper mold 11.

[0065] As a structural form of the mold assembly, see [reference needed]. Figure 3 , Figure 4 as well as Figure 5 As shown, the mold assembly includes an upper fixed frame 13 and a lower fixed frame 14. The upper fixed frame 13 is provided with the aforementioned upper mold 11, and the lower fixed frame 14 is provided with the aforementioned lower mold 12. The lower fixed frame 14 and the upper fixed frame 13 are mutually openable and closeable. At least one fixed plate 15 is fixed on the lower fixed frame 14. The fixed plate 15 has a fixed hole 150 through which a rotating shaft 22 passes. The rotating shaft 22 passes through the fixed hole 150 to be fixed on the fixed plate 15. The upper fixed frame 13 is also provided with at least one connector 16. The first end of the connector 16 is fixed on the upper fixed frame 13, and the second end of the connector 16 has a rotating hole 160 through which the rotating shaft 22 passes to achieve rotation, so that the rotating shaft 22 drives the lower fixed frame 14 to open and close relative to the upper fixed frame 13.

[0066] To ensure stability when the rotating shaft drives the lower fixed frame to open and close relative to the upper fixed frame, in this embodiment, see [reference needed]. Figure 3 , Figure 4 and Figure 5 As shown, fixing plates 15 are respectively provided on the left and right sides of the lower fixing frame 14. Correspondingly, connecting pieces 16 are also respectively provided on the left and right sides of the upper fixing frame 13. The fixing plates 15 and connecting pieces 16 on the same side are respectively matched with the rotating shaft on the same side.

[0067] Preferably, see Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the aforementioned limit switch 23 is disposed on the outer side wall of the upper fixed frame 13, and correspondingly, a protrusion 14A for touching the limit switch 23 is disposed on the outer side wall of the lower fixed frame 14.

[0068] As an implementation of the water injection mechanism, see [reference needed]. Figures 3-5 As shown, the water injection mechanism includes a water pump 31 and a connecting pipe 32. The water pump 31 is connected to a controller and is configured to pump the water required for ice making. The first end of the connecting pipe 32 is connected to the water outlet of the water pump 31, and the second end of the connecting pipe 32 is connected to the lower mold cavity 120 of the lower mold 12. For example, in this embodiment, at least one water injection hole 14a is provided at the bottom of the lower fixing frame 14. The water injection hole 14a is connected to the bottom of the corresponding lower mold cavity 120, and the water injection hole 14a is connected to the second end of the connecting pipe 32 directly or indirectly.

[0069] To ensure that the water injected by the water injection mechanism and entering through the lower mold cavity can be cooled and solidified into ice within the spherical mold cavity, as an optimization measure, see [reference needed] in this embodiment. Figure 8 and Figure 9 As shown, the bottom of the lower fixed frame 14 is provided with a water channel 140 and at least one base 141. The base 141 corresponds to and cooperates with the lower mold cavity 120. The base 141 is provided with the water injection hole 14a. The corresponding base 141, lower mold cavity 120 and upper mold cavity 110 cooperate and close to form the aforementioned spherical mold cavity. The water channel 140 is located below the base 141 and connects to the water injection holes 14a of each base 141. The water channel 140 is connected to the second end of the connecting pipe 32.

[0070] In order to form a spherical mold cavity by the cooperation and closure of the base 141, the lower mold cavity 120 and the upper mold cavity 110, in this embodiment, the upper mold cavity 110 is a hemispherical cavity, and the base 141 and the lower mold cavity 120 cooperate to form another hemispherical cavity.

[0071] As a supporting structure for the water injection mechanism, see Figures 3-5 as well as Figure 10 As shown, the ice-making system of this embodiment also includes an ice-making box 17, a temperature sensor 18, and a water level detection device 19. The ice-making box 17 forms a water storage chamber 170 for storing water required for ice making. The water storage chamber 170 is connected to the water inlet of the water pump 31. The temperature sensor 18 and the water level detection device 19 are respectively connected to the controller and are both located in the water storage chamber 170. The temperature sensor 18 is configured to detect the temperature of the water stored in the water storage chamber 170. The water level detection device 19 is configured to detect the water level of the water stored in the water storage chamber 170.

[0072] As an implementation of the cooling mechanism, see [reference needed]. Figure 3 , Figure 4 and Figure 5 As shown, the cooling mechanism includes a cooling source and a coil 3. The cooling source is connected to a controller and is configured to execute a cooling operation mode under the control of the controller to generate outward output cooling capacity. The coil 3 is disposed on the upper mold 11 and is die-cast integrally with the upper mold cavity 110. The coil 3 is configured to receive the cooling capacity supplied from the cooling source and transfer the cooling capacity to each upper mold cavity 110 of the upper mold 11. For example, the coil 3 is disposed on the upper mold 11 in a coiled manner. Preferably, the coil 3 covers the top wall of all upper mold cavities, which can accelerate the transfer efficiency of cooling capacity in the coil to the upper mold cavity and accelerate the cooling efficiency of water in the spherical mold cavity.

[0073] As an implementation of the de-icing mechanism, see [reference needed]. Figure 5As shown, the de-icing mechanism includes a heat source and a heating wire 4. 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 delivered to the aforementioned coil. The heat is transferred to each upper mold cavity of the upper mold via the coil. The heating wire 4 is located inside the lower mold 12 and below the bottom of the lower mold cavity 120. The heating wire 4 is configured to perform a heating operation to transfer heat to the bottom of each lower mold cavity 120.

[0074] As a means of implementing the aforementioned cooling and heating sources, in this embodiment, the ice-making system further includes a motor-driven compressor 5 and a solenoid valve 6. The motor-driven compressor 5 is connected to a controller and is configured to, under the control of the controller, execute a cooling mode to generate the aforementioned cold energy or a heating mode to generate the aforementioned heat. When the motor-driven compressor 5 switches to the cooling mode, it becomes the cooling source; when it switches to the heating mode, it becomes the heating source. The solenoid valve 6 is connected to the controller and is configured to open under control to cooperate with the motor-driven compressor 5 in switching between the cooling and heating modes.

[0075] The ice-making process of the ice hockey ice maker in this embodiment is described below:

[0076] When ice balls are needed, the drive source drives the rotating shaft to rotate under the control of the controller. The lower fixed frame rotates towards the upper fixed frame as the rotating shaft rotates, until the upper mold cavity on the upper mold and the lower mold cavity on the lower mold are closed. The upper mold cavity, the lower mold cavity and the corresponding base cooperate to close to form a spherical mold cavity.

[0077] The water pump draws water from the water storage chamber of the ice maker and delivers the pumped water through the connecting pipe to the water channel at the bottom of the lower fixed frame. The water in the water channel is then injected into the corresponding lower mold cavity through the water injection holes on the base. The solenoid valve opens under the control of the controller, and the motor drives the compressor to work in the refrigeration mode. The cold energy generated in the refrigeration mode is transferred to each upper mold cavity on the upper mold through the coil. As water is continuously injected from the bottom of the lower mold cavity into the spherical mold cavity and cold energy is continuously injected into the spherical mold cavity through the upper mold cavity, the water injected into the spherical mold cavity is continuously cooled and condenses, eventually forming an ice ball that matches the inner side of the spherical mold cavity.

[0078] After the ice ball is formed inside the spherical mold cavity, the solenoid valve opens in reverse under the control of the controller. The motor drives the compressor to switch to heating mode and transfers the heat generated in heating mode to each upper mold cavity through the coil. At the same time, the heating wire at the bottom of the lower mold cavity also performs heating work, and the heat generated by the heating wire is also transferred to the bottom of the lower mold cavity. In this way, the top of the ice ball will be heated by the heat transferred from the heating mode of the motor-driven compressor, 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 that is stuck to the inner wall of the upper mold cavity will melt, and the part of the ice ball that is stuck to the inner wall of the lower mold cavity will also melt. In this way, the ice ball will no longer have any parts stuck to the upper and lower mold cavities due to water cooling.

[0079] Then, under the control of the controller, the drive source drives the rotating shaft to rotate in the opposite direction. The lower fixed frame gradually moves away from the upper fixed frame. The ice ball is located in the lower mold cavity, and the lower mold cavity rotates away from the upper mold cavity until the lower mold cavity rotates to the preset rotation stroke (reaching the aforementioned predetermined angle). At this time, a large space is formed between the lower mold cavity and the upper mold cavity. The ice ball falls out of the lower mold cavity due to the tilting of the lower mold cavity during rotation and falls into the ice ball collection chamber of the ice ball making machine, thus obtaining the required ice ball.

[0080] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
