[0002] An ice hockey maker is a refrigeration device that cools water through a refrigeration system, creating ice balls (or spherical ice). The refrigeration system freezes water into ice balls within a mold (specifically, a spherical cavity) of the ice-making mechanism. These ice balls, made using an ice hockey maker, are then added to beverages to satisfy customers' desire for a chilled and flavorful drink. Currently, due to the high demand for ice balls in commercial and entertainment venues such as bars, existing ice hockey makers primarily supply these establishments.

[0003] Currently, existing hockey ice makers have shortcomings: hockey ice makers are commercial ice makers, and because they are mainly supplied to commercial entertainment venues such as bars, and require the production of more hockeys, the structure of hockey ice makers is complex and large, and the price is expensive. They cannot meet people's demand for hockey ice making in home environments, which also limits the expansion of the application scenarios of hockey ice makers. Utility Model Content

[0031] The solenoid valve, connected to the controller, is configured to open under control to cooperate with the motor to drive the compressor to switch between cooling and heating modes.

[0032] Compared with the prior art, the advantages of this utility model are:

[0033] Firstly, the ice-making system of the ice hockey maker in this utility model comprises a mold assembly, a drive mechanism, a water injection mechanism, a cooling source, a heating source, a heat transfer medium, a heating element, 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 with each other. The upper and lower mold cavities are closed to form a spherical mold cavity. The heat transfer medium is embedded in the upper mold cavity and located outside the upper mold cavity. The heating element is embedded in the lower mold cavity and located outside the lower mold cavity. The cooling energy generated by the cooling source is transported to the spherical mold cavity through the heat transfer medium, causing the water in the spherical mold cavity to cool and condense into an ice ball. The heat generated by the heating source is conducted to the spherical mold cavity through the heat transfer medium, and the heat generated by the heating element is also conducted to the spherical mold cavity to melt the ice that has formed at the cooling and bonding point between the ice ball and the inner wall of the spherical mold cavity. After the drive mechanism drives the mold assembly, the desired ice ball is obtained. Thus, this ice hockey ice maker not only has a simple structure, but can also meet the ice-making needs of a home environment;

[0034] Secondly, the ice hockey maker in this utility model embeds the heat transfer medium in the upper mold and is located outside the upper mold cavity, and embeds the heating element in the lower mold and is located outside the lower mold cavity. This can achieve uniform cooling of the water in the spherical mold cavity, and uniform melting of the ice formed at the cooling and bonding point between the ice hockey obtained in the spherical mold cavity and the inner wall of the spherical mold cavity. This not only makes it convenient to obtain ice hockey, but also avoids cracking of the outer wall of the ice hockey.

[0035] Finally, the ice-making system of this utility model ice hockey machine employs a controlled motor-driven compressor and a solenoid valve. By controlling the solenoid valve, the motor-driven compressor can switch between cooling and heating modes. This ensures that the cooling capacity generated by the motor-driven compressor in cooling mode and the heat generated in heating mode are evenly conducted to the spherical mold cavity through the embedded heat transfer medium. This process completes the cooling and ice formation of water in the spherical mold cavity and the melting of ice that forms at the cooling and bonding points between the resulting ice hockey ball and the inner wall of the spherical mold cavity. This improves the ice-making efficiency and quality of the ice hockey ball, and enhances its appearance, making it more complete and aesthetically pleasing. Attached Figure Description

[0049] 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.

[0050] 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.

[0051] This embodiment provides an ice hockey maker for manufacturing ice hockey pucks. See also: Figures 1-12As shown, the ice hockey ice maker of this embodiment includes an ice-making system and a housing assembly. The ice-making system is located inside the housing assembly, which includes an upper cover plate C1, a left cover plate C2, and a right cover plate C3. The ice-making system includes a mold assembly, a drive mechanism, a water injection mechanism, a cooling source, a heating source, a heat transfer medium, a heating element, and a controller (not shown in the figure). The controller is connected to the drive mechanism, the water injection mechanism, the cooling source, the heating source, and the heating element.

[0052] The mold assembly includes an upper mold 11 and a lower mold 12 that open and close to each other. The upper mold 11 has an upper mold cavity 110, and the lower mold 12 has a lower mold cavity 120. The upper mold cavity 110 and the corresponding lower mold cavity 120 close to each other to form a spherical mold cavity. For example, the upper mold cavity 110 is a hemispherical cavity, while the lower mold cavity 120 has a hemispherical cavity main structure.

[0053] The drive mechanism is configured to perform drive work after being controlled, so as to drive the lower mold 12 of the mold assembly to move relative to the upper mold 11, so as to realize the opening and closing cooperation between the lower mold and the upper mold;

[0054] The water injection mechanism is configured to perform water injection work 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 work under the control of the controller.

[0055] The cooling source is configured to perform cooling operations under control to generate cooling capacity; the heating source is configured to perform heating operations under control to generate heat.

[0056] The heat transfer medium 13 is embedded in the upper mold 11 and located outside the upper mold cavity 110. The heat transfer medium 13 is configured to transfer the cold energy received from the cooling source to the upper mold cavity 110 to cool the water in the spherical mold cavity and cause it to condense into ice after cooling; and to transfer the heat received from the heating source to the upper mold cavity 110 to transfer heat to the cooling and bonding area between the ice ball obtained after cooling and condensation in the spherical mold cavity and the inner wall of the spherical mold cavity, melting the ice at the cooling and bonding area; for example, the heat transfer medium 13 here is a tubular structure; as needed, the connection between the cooling source / heating source and the heat transfer medium 13 can be realized through an intermediate component to achieve the corresponding cold / heat transfer effect of the heat transfer medium;

[0057] The heating element 14 is embedded in the lower mold 12 and located on the outside of the lower mold cavity 120. The heating element 14 is configured to perform heating operations under control to transfer heat into the lower mold cavity. For example, the heating element 14 is a heating wire controlled by a controller.

[0058] The controller controls the driving operation of the drive mechanism, the water injection action of the water injector, the cooling operation of the refrigeration source, the heating operation of the heating source, and the heating operation of the heating element. The controller can be set at a suitable location on the ice hockey maker according to actual needs.

[0059] To improve the efficiency of both cold and heat conduction within the upper mold cavity, in this preferred embodiment, the heat conduction medium 13 is embedded in the upper mold 11 in a manner that surrounds the upper mold cavity 110. That is, the heat conduction medium 13 is distributed around the upper mold cavity, so that during cooling, the cold energy received by the heat conduction medium from the cooling source can be conducted towards the inside of the upper mold cavity from multiple directions, greatly improving the corresponding cooling effect within the upper mold cavity; during heating, the heat received by the heat conduction medium from the heating source can also be conducted towards the inside of the upper mold cavity from multiple directions, greatly improving the corresponding heating effect within the upper mold cavity.

[0060] Of course, the heating element 14 can also be embedded in the lower mold 12 in a ring around the lower mold cavity 120, so as to improve the heat generated by the heating element when performing the heating work, so that the heat can be transferred to the lower mold 12 from multiple directions, thereby improving the ice melting effect of the ice ball obtained in the core mold cavity and the cooling bonding point of the spherical mold cavity.

[0061] Preferably, the heat transfer medium 13 is embedded in the upper mold 11 in a manner that surrounds the upper mold cavity 110, and the heating element 14 is embedded in the lower mold 12 in a manner that surrounds the lower mold cavity 120.

[0062] It should be noted that, in this embodiment, 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 accordingly according to actual needs.

[0063] Regarding the driving action of the drive mechanism on the lower mold, in this embodiment, the lower mold 12 rotates relative to the upper mold 11. That is, after performing the driving operation, the drive mechanism can cause the lower mold to 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 performing the reverse driving operation, the lower mold rotates away from the upper mold, the lower mold and the upper mold separate, the lower mold cavity and the corresponding upper 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, so that the ice ball located in the lower mold cavity can be released from the lower mold cavity.

[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, driven by the drive source 21, to drive the lower mold 12 to open and close 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 during the opening and closing process relative to the upper mold. 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 to rotate away from the upper mold.

[0065] As a structural form of the mold assembly, see [reference needed]. Figures 3-6 As shown, the mold assembly includes an upper fixed frame 15 and a lower fixed frame 16. The upper fixed frame 15 is fixed with the aforementioned upper mold 11, and the lower fixed frame 16 is provided with the aforementioned lower mold 12. The lower fixed frame 16 and the upper fixed frame 15 are mutually openable and closeable. At least one fixed plate 17 is fixed on the lower fixed frame 16. The fixed plate 17 has a fixed hole 170 through which a rotating shaft 22 passes. The rotating shaft 22 passes through the fixed hole 170 to be fixed on the fixed plate 17. The upper fixed frame 15 is also provided with at least one connector 18. The first end of the connector 18 is fixed to the upper fixed frame 15, and the second end of the connector 18 is provided with a rotating hole 180 through which the rotating shaft 22 passes to achieve rotation, so that the rotating shaft 22 drives the lower fixed frame 16 to open and close relative to the upper fixed frame 15.

[0066] To accommodate the need for fixing the upper mold in the upper fixed frame, as an improvement, the upper fixed frame 15 is provided with a placement hole 150 for the upper mold to be inserted.

[0067] 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 6 As shown, a fixing plate 17 is provided on the left and right sides of the lower fixing frame 16, and correspondingly, a connector 18 is provided on the left and right sides of the upper fixing frame 15. The fixing plate 17 and the connector 18 on the same side are respectively matched with the rotating shaft on the same side.

[0068] Preferably, see Figures 1-3 , Figure 6 As shown, the aforementioned limit switch 23 is disposed on the outer side wall of the upper fixed frame 15, and correspondingly, a protrusion 16A for touching the limit switch 23 is disposed on the outer side wall of the lower fixed frame 16.

[0069] As an implementation of the water injection mechanism, see [reference needed]. Figures 3-6 As shown, the water injection mechanism includes a water pump 3, which is connected to a controller and is configured to pump the water required for ice making. The water outlet of the water pump 3 is connected to the lower mold cavity 120 of the lower mold 12 directly or indirectly to deliver the pumped water into the lower mold cavity 120.

[0070] 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, in this embodiment, see [reference needed]. Figure 4 , Figure 5 , Figure 6 and Figure 11 As shown, a water injection hole 160 is provided at the bottom of the lower fixed frame 16. The water injection hole 160 is connected to the bottom of the lower mold cavity 120. The water injection hole 160 is connected to the water outlet of the water pump 3 directly or indirectly.

[0071] Of course, the bottom of the lower fixing frame 16 can be further provided with a base 161, which corresponds to and cooperates with the lower mold cavity 120. The base 161 is provided with the aforementioned water injection hole 160. The corresponding base 161, lower mold cavity 120, and upper mold cavity 110 cooperate and close to form the spherical mold cavity, with the base 161 tightly fitted to the bottom of the lower mold cavity 120. After the base 161 and the bottom of the lower mold cavity 120 are tightly fitted, the overall shape is a hemispherical cavity. For example, in this embodiment, the base 161 is a concave circular shape, so that it forms a hemispherical cavity after tightly fitting with the bottom of the lower mold cavity 120.

[0072] As a cooperating structure with the water injection mechanism, the ice-making system of this embodiment also includes an ice-making box 41 and a temperature sensor 42. The ice-making box 41 forms a water storage chamber 410 for storing water required for ice making. The water storage chamber 410 is connected to the water inlet of the water pump 3. The temperature sensor 42 is connected to the controller and is disposed in the water storage chamber 410. The temperature sensor 42 is configured to detect the temperature of the water stored in the water storage chamber 410.

[0073] 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.

[0074] The ice-making process of the ice hockey ice maker in this embodiment is described below:

[0075] 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 of the upper mold and the lower mold cavity of 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.

[0076] The water pump draws water from the water storage chamber of the ice maker and injects the pumped water into the lower mold cavity through the water injection hole of the base; the solenoid valve opens under the control of the controller, the motor drives the compressor to work in the refrigeration mode, and the cold energy generated in the refrigeration mode is conducted to the upper mold cavity through the heat conduction medium. As water is continuously injected into the spherical mold cavity from the bottom of the lower mold cavity and cold energy is continuously injected into the spherical mold cavity from multiple directions around 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;

[0077] After an 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 the heat generated in the heating mode is conducted from multiple directions around the upper mold cavity to the upper mold cavity through the heat conduction medium. At the same time, the heating wire embedded in the lower mold cavity also performs heating work under the control of the controller. The heat generated by the heating wire is continuously conducted from multiple directions around the lower mold cavity to the lower mold cavity. In this way, the ice formed by the ice ball cooling and bonding with the cavity wall of the spherical mold cavity will melt due to heat, so that there is no part of the ice ball bonded to the upper mold cavity and the lower mold cavity due to water cooling and freezing.

[0078] 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 storage box of the ice ball maker, thus obtaining the required ice ball.

[0079] 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.
