Technical Field
[0001] This utility model relates to the technical field of ice-making devices, and in particular to an ice-making device with uniform heating and equipment having an ice-making device. Background Technology
[0002] In 2024, our company developed an ice-making device for ice making. Details can be found in the Chinese Utility Model Patent Publication No. 2024227553479, entitled "An Ice-Making Mechanism." This patent discloses that existing ice-making devices typically use a single heating element on the outside of the ice mold, or directly heat the ice mold through the reverse flow of refrigerant within a refrigeration pipe, and then heat the ice blocks through heat conduction within the ice mold body, thus promoting ice removal. However, these heating and ice removal methods suffer from significant problems of uneven heating and low heating efficiency. In the single heating element method, the contact area between the heating element and the outer surface of the mold is limited, and the heat transfer path within the mold is fixed. Heat can only diffuse from one direction into the mold, causing the area near the heating element to heat up rapidly, while the area away from the heating element heats up slowly, creating a significant temperature gradient and resulting in uneven heating of the ice blocks. In the refrigerant reverse flow heating method, the flow state of the refrigerant within the pipe is unstable, easily leading to localized excessively fast or slow flow rates, resulting in uneven heat distribution to different parts of the mold, also causing uneven ice block heating.
[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content
[0004] This invention addresses the problems of uneven heating and low heating efficiency in existing ice-making devices, which typically involve setting a single heating element on the outside of the ice mold or directly heating the ice mold by reverse flow of refrigerant in the refrigeration pipe and then conducting heat through the ice mold body to heat the ice blocks and promote de-icing. The present invention proposes an ice-making device with uniform heating and an equipment having an ice-making device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: An ice-making device with uniform heating includes an ice-making mold, which has at least one ice-making cavity. A heating element is provided in the ice-making mold near the ice-making cavity. An electromagnetic induction coil is provided on the ice-making mold to generate electromagnetic induction with the heating element, thereby generating heat in the heating element. This allows the heating element to heat the ice-making cavity, thereby separating the ice block in the ice-making cavity from the cavity wall.
[0006] As described above, in a uniformly heated ice-making device, the heating element is disposed inside the ice-making mold, the ice-making cavity is located inside the heating element, and the heating element is made of a thermally conductive non-metallic material containing metal powder and / or metal blocks, so that the metal powder and / or metal blocks inside the heating element can interact with an electromagnetic induction coil to generate heat.
[0007] As described above, in a uniformly heated ice-making device, the ice-making mold includes an inner shell module and an outer shell module disposed outside the inner shell module. The electromagnetic induction coil is disposed outside the outer shell module, the ice-making cavity is disposed inside the inner shell module, and the heating element is located between the inner shell module and the outer shell module.

[0012] As described above, in a uniformly heated ice-making device, the ice-making mold has an external mounting groove for mounting the electromagnetic induction coil.
[0013] As described above, in a uniformly heated ice-making device, the outer shell module includes a first outer mold shell and a second outer mold shell, and the inner shell module includes a first inner mold shell and a second inner mold shell. The first inner mold shell is disposed inside the first outer mold shell and forms a first half-mold, and the second inner mold shell is disposed inside the second outer mold shell and forms a second half-mold. The first half-mold and the second half-mold have a mold-closing state and a mold-separating state corresponding to ice making and ice removal, respectively. The ice-making cavity is formed by the first inner mold shell and the second inner mold shell. The heating element is disposed on the first inner mold shell and / or the second inner mold shell, and the electromagnetic induction coil is disposed outside the first outer mold shell and / or the second outer mold shell.
[0014] This utility model also provides an apparatus with an ice-making device, including the ice-making device described above.
[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention provides an ice-making device with uniform heating. The heating element is placed inside the ice mold and close to the ice-making cavity. Electromagnetic induction is generated between the heating element and the electromagnetic induction coil, causing the heating element to generate heat. The heating element can directly heat the ice in the ice-making cavity, shortening the heat conduction path, reducing heat loss during the transfer process, improving heat conduction efficiency, and ensuring that the ice is heated uniformly, which is beneficial to improving the ice removal efficiency.

[0021] Example 1: like Figure 1 , 2 As shown in Figures 6 and 7, this utility model provides a uniformly heated ice-making device. The ice-making device can be used in ice makers, refrigerators, and other devices with ice-making functions. The ice-making device includes an ice-making mold 1, which has at least one ice-making cavity 11. A heating element 3 is located near the ice-making cavity 11 in the ice-making mold 1. An electromagnetic induction coil 2 is provided on the ice-making mold 1, which can generate electromagnetic induction with the heating element 3, thereby causing the heating element 3 to generate heat. This allows the heating element 3 to heat the ice-making cavity 11, thus separating the ice blocks inside the ice-making cavity 11 from the cavity wall. In this embodiment, the ice-making mold 1 is used to receive liquid and freeze it into ice. The liquid includes at least edible pure water, fruit juice, etc. The interior of the ice-making mold 1... Multiple ice-making chambers 11 can be arranged at intervals. In practical applications, the ice-making mold 1 has a closed mold state and a open mold state corresponding to ice making and ice removal, respectively. During ice making, the ice-making mold 1 is in the closed mold state, water enters the ice-making chamber 11 and freezes, while the electromagnetic induction coil 2 remains in a non-working state to avoid heat interference with the freezing process. During ice removal, alternating current is passed through the electromagnetic induction coil 2, causing it to generate an alternating magnetic field. The heating element 3 induces eddy currents in the alternating magnetic field and generates heat, thereby generating heat on the cavity wall of the ice-making chamber 11 to appropriately heat the ice and separate it from the cavity wall. When the ice-making mold 1 switches to the open mold state, the ice can detach from the ice-making mold 1 under the action of gravity, thus achieving ice removal. It should be noted that the electromagnetic induction heating principle between the electromagnetic induction coil 2 and the heating element 3 in this embodiment is similar to the electromagnetic heating principle of an induction cooker.
[0022] In this invention, the heating element 3 is placed inside the ice-making mold 1, close to the ice-making cavity 11. Electromagnetic induction is generated between the electromagnetic induction coil 2 and the heating element 3, causing the heating element 3 to generate heat. The heating element 3 can directly heat the ice in the ice-making cavity 11, shortening the heat conduction path, reducing heat loss during the transfer process, improving heat conduction efficiency, and ensuring that the ice is heated evenly, which is beneficial to improving the de-icing efficiency. In addition, compared with the traditional electric heating method, electromagnetic induction heating has higher heating efficiency and is safer and more reliable.
[0023] Optionally, the ice-making cavity 11 can be configured as a spherical cavity, a square cavity, etc., which can be used to make ice blocks of different shapes and sizes, such as spherical ice blocks and cube ice blocks. This utility model does not make any specific limitations.
[0024] In one alternative embodiment of the heating element 3, such as Figure 2 As shown, the heating element 3 is disposed inside the ice-making mold 1, and the ice-making cavity 11 is located inside the heating element 3. The heating element 3 is made of a thermally conductive non-metallic material containing metal powder and / or metal blocks, so that the metal powder and / or metal blocks inside the heating element 3 can interact with the electromagnetic induction coil 2 to generate heat. Optionally, the metal powder and metal blocks can be made of metal materials such as iron and copper that can generate electromagnetic induction heating. The thermally conductive non-metallic material includes silicone, rubber, etc., and this utility model does not make specific limitations. In the production process, the metal powder and / or metal blocks and the thermally conductive non-metallic material are integrally molded to form the heating element 3. For example, iron powder and / or iron blocks can be integrally injection molded with silicone, or iron powder and / or iron blocks can be integrally injection molded with rubber. The heating element 3 is formed by molding, and it directly serves as the inner mold shell in the ice-making mold 1. The metal powder and / or metal blocks are evenly distributed in the heating element 3. During ice removal, the metal powder and / or metal blocks in the heating element 3 are heated by the electromagnetic induction coil 2, thereby heating the entire heating element 3. The heating element 3 directly heats the ice in the ice-making cavity 11, making the ice evenly heated and further improving the heating effect of the ice, thus improving the ice removal efficiency. In addition, the heating element 3 is made of a thermally conductive non-metallic material containing metal powder and / or metal blocks, and it directly forms the inner mold shell in the ice-making mold 1, which simplifies the assembly steps of the ice-making mold 1 and helps to improve the production and assembly efficiency of the ice-making device.
[0025] Alternatively, the thickness of the heating element 3 can be set to 0.5mm to 3mm.
[0026] In some alternative embodiments, such as Figure 1As shown, the electromagnetic induction coil 2 is equipped with a connector 22 that connects to the control board, through which the control board supplies power to the electromagnetic induction coil 2. In practical applications, since the ice-making device is generally installed in equipment with ice-making functions such as ice makers and refrigerators, the connector 22 can be electrically connected to the control board in the equipment to simplify the circuit connection of the electromagnetic induction coil 2. Further optionally, the electromagnetic induction coil 2 can be configured as an induction coil or a circuit board with an induction coil, with the connector 22 located at one end of the electromagnetic induction coil 2.
[0027] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the ice-making mold 1 is provided with an installation groove 121 for installing the electromagnetic induction coil 2. The installation groove 121 faces the outside of the ice-making mold 1. The electromagnetic induction coil 2 can be installed through the installation groove 121, which can reduce the overall volume of the ice-making device and save installation space. Optionally, the electromagnetic induction coil 2 can be fixedly installed on the outside of the ice-making mold 1 by means of snap-fit, screw assembly or other methods, which is easy to disassemble and install and maintain later.
[0028] Example 2: This second embodiment provides another optional embodiment of the heating element 3. The difference between this second embodiment and the first embodiment described above is that, as... Figures 3 to 5 As shown, the ice-making mold 1 includes an inner shell module 13 and an outer shell module 12 disposed outside the inner shell module 13. The electromagnetic induction coil 2 is disposed outside the outer shell module 12. The ice-making cavity 11 is disposed inside the inner shell module 13. The heating element 3 is located between the inner shell module 13 and the outer shell module 12. In this embodiment, the heating element 3 and the inner shell module 13 are set separately. The heating element 3 can compensate for the assembly gap between the outer shell module 12 and the inner shell module 13, thereby ensuring that heat can be evenly and efficiently transferred to the entire inner shell module 13 to evenly heat the ice block in the ice-making cavity 11.
[0029] Furthermore, the heating element 3 is a metal sheet that can interact with the electromagnetic induction coil 2 to generate heat; optionally, the metal sheet can be an iron sheet, a copper sheet, etc., and this utility model does not make a specific limitation; Figure 4 As shown, the heating element 3 can be configured as a metal mold shell, the inner side of which is adapted to the outer contour of the inner shell module 13, so that the metal mold shell can cover each of the ice-making cavities 11, which is beneficial to increase the heating area of the heating element 3 on the ice-making cavity 11. The inner side of the outer shell module 12 is adapted to the outer contour of the metal mold shell. When energized, the electromagnetic induction coil 2 generates electromagnetic induction with the metal mold shell, causing the metal mold shell to heat up, and the metal mold shell heats the inner shell module 13, so that the ice in the ice-making cavity 11 is heated evenly, improving the heating efficiency of the ice.
[0030] In some alternative embodiments, the heating element 3 may be embedded inside the outer shell module 12 to keep the mounting surface of the outer shell module 12 compatible with the outer contour of the inner shell module 13, so as to reduce the volume of the ice-making mold 1 and save the installation space of the ice-making mold 1 in the equipment.
[0031] In some optional embodiments, the inner shell module 13 is made of a thermally conductive non-metallic material. Optionally, the thermally conductive non-metallic material includes silicone, rubber, etc. The inner shell module 13, which has an ice-making cavity 11 inside, is integrally formed by the thermally conductive non-metallic material. The inner shell module 13 can be tightly fitted and installed inside the heating element 3. Thermally conductive non-metallic materials such as silicone and rubber have high thermal conductivity and can quickly conduct the heat of the heating element 3 to the ice-making cavity 11 to achieve uniform heating of the ice cubes in the ice-making cavity 11. At the same time, thermally conductive non-metallic materials such as silicone and rubber have smooth surfaces and are non-stick, making it difficult for ice cubes to adhere, reducing the difficulty of removing ice cubes, reducing the damage of ice cubes during the removal process, and ensuring the integrity of ice cubes. In addition, thermally conductive non-metallic materials such as silicone and rubber also have good high and low temperature resistance, can adapt to the low temperature environment during ice making and the heating process during ice removal, and have strong chemical stability, are not easy to react with water or other substances, are safe and non-toxic, and meet the requirements of food contact materials.
[0032] In some alternative embodiments, such as Figure 5As shown, the outer shell module 12 has a water inlet channel 122 communicating with the ice-making cavity 11. The outer shell module 12 has a first connecting portion 123 and a second connecting portion 124 on both sides. The water inlet channel 122 extends to the first connecting portion 123 and the second connecting portion 124. The electromagnetic induction coil 2 has a first opening 21 through which the first connecting portion 123 can pass. The inner shell module 13 has a second opening 131 corresponding to the second connecting portion 124, and the second connecting portion 124 is adaptedly disposed within the second opening 131. In this embodiment, the first connecting portion 123 can be configured as a cylindrical connecting portion to facilitate connection to an external pipeline and to an external water source. This external pipeline communicates with the water inlet channel 122 to inject water into the ice-making cavity 11. The external water source can be an ice maker, refrigerator, or other similar equipment. The water tank 5 in this utility model is not specifically limited; the heating element 3 is provided with a relief opening 31 corresponding to the second connecting part 124. The relief opening 31 allows the second connecting part 124 to pass through, so that the second connecting part 124 can be connected to the second opening 131 of the inner shell module 13, thereby improving the structural tightness of the ice-making mold 1, reducing the assembly gap between the outer shell module 12, the heating element 3 and the inner shell module 13, further shortening the heat conduction path and improving the heating efficiency of the ice cube; in addition, since the inner shell module 13 is made of silicone, the inner shell module 13 can be tightly connected to the heating element 3. At the same time, the second connecting part 124 is installed in the second opening 131 of the inner shell module 13, and the silicone inner shell module 13 can directly act as a sealing ring to prevent water leakage between the inner shell module 13 and the outer shell module 12, ensuring that the heating element 3 heats up normally.
[0033] Furthermore, the inner diameter of the first opening 21 is greater than or equal to the outer diameter of the first connecting part 123, ensuring that the first connecting part 123 can pass through the first opening 21. The electromagnetic induction coil 2 can be sleeved on the first connecting part 123 through the first opening 21, which helps to improve the connection stability of the electromagnetic induction coil 2.
[0034] Example 3: Based on the above-described Embodiment 1 or Embodiment 2, this Embodiment 3 provides another optional embodiment of the ice-making mold 1, such as... Figure 6 and Figure 7As shown, the ice-making mold 1 includes an inner shell module 13 and an outer shell module 12 disposed outside the inner shell module 13. The electromagnetic induction coil 2 is disposed outside the outer shell module 12. The ice-making cavity 11 is disposed inside the inner shell module 13. The outer shell module 12 includes a first outer shell 12a and a second outer shell 12b. The inner shell module 13 includes a first inner shell 13a and a second inner shell 13b. The first inner shell 13a is disposed inside the first outer shell 12a and forms a first half-mold 101. The second inner mold shell 13b is disposed inside the second outer mold shell 12b and forms the second half mold 102. The first half mold 101 and the second half mold 102 have a mold-closed state and a mold-separated state corresponding to ice making and ice removal, respectively. The ice-making cavity 11 is formed by the first inner mold shell 13a and the second inner mold shell 13b. The heating element 3 is disposed on the first inner mold shell 13a and / or the second inner mold shell 13b. The electromagnetic induction coil 2 is disposed on the outside of the first outer mold shell 12a and / or the second outer mold shell 12b.
[0035] Optionally, both the first inner mold shell 13a and the second inner mold shell 13b are made of heating element 3. At least one of the first outer mold shells 12a and 12b is provided with the electromagnetic induction coil 2 on its exterior. The heating element 3 is made of a thermally conductive non-metallic material containing metal powder and / or metal blocks, so that the first inner mold shell 13a and the second inner mold shell 13b can directly interact with the electromagnetic induction coil 2 and generate heat, thereby heating the ice in the ice-making cavity 11. When the first half mold 101 and the second half mold 102 are in the closed state, the inner mold shells on both sides are tightly fitted to achieve a sealed closure between the first half mold 101 and the second half mold 102, thereby improving the ice-making quality.
[0036] Alternatively, one of the inner mold shells 13a and 13b may be made of a heating element 3, which is made of a thermally conductive non-metallic material containing metal powder and / or metal blocks. The other inner mold shell may be made of a thermally conductive non-metallic material such as silicone or rubber. At least one of the outer mold shells 12a and 12b may have the electromagnetic induction coil 2 disposed on its exterior. The electromagnetic induction coil 2 generates electromagnetic induction with the heating element 3, and further heat is transferred between the inner mold shells on both sides to heat the ice in the ice-making cavity 11.
[0037] Alternatively, both the first inner mold shell 13a and the second inner mold shell 13b are made of thermally conductive non-metallic materials such as silicone or rubber. A heating element 3 is provided on the outside of the first inner mold shell 13a and / or the second inner mold shell 13b. The heating element 3 is a metal sheet. The electromagnetic induction coil 2 is provided on the outside of at least one of the first outer mold shell 12a and the second outer mold shell 12b. The electromagnetic induction coil 2 generates electromagnetic induction with the heating element 3, and the heating element 3 conducts heat to the first inner mold shell 13a or the second inner mold shell 13b. At the same time, further heat transfer occurs between the two inner mold shells to heat the ice in the ice-making cavity 11. When the first half mold 101 and the second half mold 102 are in the closed state, the inner mold shells on both sides are tightly fitted to achieve a sealed closure between the first half mold 101 and the second half mold 102, thereby improving the ice-making quality.
[0038] Furthermore, the ice-making device also includes an opening and closing drive device 4 connected to the first half-mold 101 and / or the second half-mold 102. The opening and closing drive device 4 can be configured as a rotary drive device or a linear translation drive device to realize the relatively closed ice-making mold state between the first half-mold 101 and the second half-mold 102, and the relatively separated ice-removing mold state. For example, the first half-mold 101 and the second half-mold 102 can be rotated relatively closer or further apart by the rotary drive device to switch between the mold-closing state and the mold-separating state. Another example is that the first half-mold 101 and the second half-mold 102... The half-mold 102 can move relatively closer to or further away from each other via a linear translation drive device to switch between the mold-closing state and the mold-separating state. Both the rotary drive device and the linear translation drive device can be set with reference to the mold-opening and closing drive module in the existing ice-making device. The mold-opening and closing drive module can be equipped with a mold-closing locking structure to facilitate maintaining the closed and fixed relationship between the two half-molds during the ice-making process, thereby ensuring the smooth progress of ice-making. In addition, the mold-opening and closing drive module can be equipped with a motor, which can control the opening and closing stroke range between the first half-mold 101 and the second half-mold 102.
[0039] In practical applications, the first half-mold 101 and the second half-mold 102 can be set as a fixed mold and a moving mold, respectively, to reduce the opening and closing stroke of the ice-making mold 1, thereby reducing the space occupied by the ice-making device.

The device with an ice-making device includes at least ice makers, refrigerators, beverage machines, and other devices with ice-making functions. The device with an ice-making device includes a device body and an ice-making device as described in any of the above embodiments. The ice-making device is installed in the device body, and the device body has an ice storage cavity. The ice-making device is located above the ice storage cavity so that the ice blocks can fall directly into the ice storage cavity when the ice mold 1 is in the mold-opening state.
