[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figures 1 to 4This application provides an ice maker 100, including a main body 10 and a door assembly 20. The main body 10 has a receiving cavity 111 and an opening 112, the opening 112 connecting the receiving cavity 111 to the outside. The receiving cavity 111 is used to receive finished solid ice cubes, and the opening 112 is used for a user to take out the ice cubes. The main body 10 has a first hinge portion 113, and the first hinge portion 113 has a first protrusion 1141. The door assembly 20 has a second hinge portion 211, the second hinge portion 211 being rotatably connected to the first hinge portion 113, and the door assembly 20 is configured to rotate to open or rotate to close the opening 112. The second hinge portion 211 has a second protrusion 241, the second protrusion 241 engaging with the first protrusion 1141, and the second protrusion 241 being configured to abut against and cross the first protrusion 1141, causing the door assembly 20 to produce a tactile feedback. In this embodiment of the application, the ice maker 100 has a first protrusion 1141 on the main body 10 and a second protrusion 241 on the door assembly 20, and the first protrusion 1141 and the second protrusion 241 are arranged opposite to each other. When the door assembly 20 is driven to rotate relative to the main body 10, and the second protrusion 241 crosses the first protrusion 1141, the door assembly 20 moves with a jerking motion relative to the main body 10, and the door assembly 20 produces a jerking feel. This jerking feel can provide feedback to the user to improve the feel when rotating the door assembly 20 and improve the user experience.

[0028] In some embodiments, the main body 10 includes a first housing 11, which has a first hinge portion 113. The first hinge portion 113 has a first channel 1131 extending along a first direction X. The first hinge portion 113 has a rotation axis when rotatably connected to a second hinge portion 211, and the first direction X is parallel to this rotation axis. A first protrusion 1141 is disposed on the side of the first hinge portion 113 in the first direction X. The door assembly 20 includes a first door panel 21 and a first pivot 22. The first door panel 21 has a second hinge portion 211, a second channel 212 extending along the first direction X, and a third channel 213 (e.g., ...). Figure 8 (As shown).

[0029] As an example, the first hinge portion 113 is a convex portion, and the second hinge portion 211 is a concave portion. Along the first direction X, the second channel 212 and the third channel 213 are located on both sides of the second hinge portion 211 and communicate with it. The second hinge portion 211 accommodates the first hinge portion 113, and the two can be nested and rotated relative to each other. The second channel 212, the first channel 1131, and the third channel 213 are sequentially connected in the first direction X. A first rotating shaft 22 passes through the first channel 1131, the second channel 212, and the third channel 213. The first rotating shaft 22 rotatably connects the first door panel 21 to the first housing 11.

[0030] Please see Figure 4The second protrusion 241 is disposed on the side of the second hinge portion 211 along the first direction X, and is disposed opposite to the first protrusion 1141. During the rotation of the first door panel 21 relative to the first housing 11, the first protrusion 1141 moves against the side wall of the second hinge portion 211, and the second protrusion 241 moves against the side wall of the first hinge portion 113. There is at least one position where the second protrusion 241 and the first protrusion 1141 abut against each other. When the second protrusion 241 continues to move relative to the first protrusion 1141, the second protrusion 241 will cross over the first protrusion 1141 along the surface of the first protrusion 1141. During this crossing process, the first door panel 21 produces a jerky movement relative to the first housing 11 to generate a jerky feeling. This jerky feeling can be fed back to the user, thereby allowing the user to perceive the rotation status and position of the first door panel 21. For example, users can use this tactile feedback to know whether the first door panel 21 is in a completely closed state, a completely open state, a half-open state, or other preset open state.

[0031] This explanation uses the example of a user knowing that the first door panel 21 is in a state where the opening 112 is completely closed. Please refer to [link / reference needed]. Figure 2 Along the circumferential direction of the first hinge portion 113, the first protrusion 1141 has a first travel 114a and a second travel 114b on both sides. When the second protrusion 241 switches between the first travel 114a and the second travel 114b, it must cross the first protrusion 1141. When the second protrusion 241 is in the first travel 114a, the first door panel 21 closes the opening 112; when the second protrusion 241 is in the second travel 114b, the first door panel 21 is in the open state of the opening 112. The area on the first hinge portion 113 is divided into the first travel 114a and the second travel 114b by the first protrusion 1141. By controlling the length (radius) of the first travel 114a, when the second protrusion 241 crosses the first protrusion 1141 from the second travel 114b to the first travel 114a, the first door panel 21 just completely closes the opening 112. In this way, when the user closes the first door panel 21 and feels a jolt when the first door panel 21 moves, they can confirm that the first door panel 21 has completely closed the opening 112. This avoids the need for the user to repeatedly push the first door panel 21 to confirm whether the opening 112 is completely closed, greatly improving the user experience.

[0032] In other embodiments, the length (radian) of the first stroke 114a can be appropriately increased, so that the position of the first protrusion 1141 moves downward. When the first door panel 21 is driven to move from the first stroke 114a to the second stroke 114b, the second protrusion 241 abuts against the first protrusion 1141. If the user removes the force at this time, the first door panel 21 can be suspended at the current position. When the user continues to apply force to drive the first door panel 21 to rotate, the second protrusion 241 crosses the first protrusion 1141, and the first door panel 21 produces a jerking sensation to indicate to the user the movement position of the first door panel 21, such as the first door panel 21 has passed half of the opening and closing distance.

[0033] In some embodiments, Figure 7 and Figure 8 The first rotating shaft 22 includes a head 221, a middle portion 222, and a tail portion 223. The head 221 and tail portion 223 are respectively connected to the two ends of the middle portion 222 along the first direction X. The tail portion 223 is provided with external threads. A portion of the middle portion 222 passes through the second channel 212, the first channel 1131, and the third channel 213. The head 221 and tail portion 223 are respectively located at the two ends of the first hinge portion 113 along the first direction X. The door assembly 20 also includes a first fixing member 23, which is fixed to the first door panel 21 and screwed to the tail portion 223, so that the first rotating shaft 22 is fixed relative to the first hinge portion 113 and the second hinge portion 211 in the first direction X, ensuring the connection stability between the first door panel 21 and the first housing 11.

[0034] As an example, the first rotating shaft 22 can be a screw, with no threads in the middle section, and the first fixing member 23 is a nut. The nut is integrally injection molded with the first door panel 21, or the first door panel 21 has a countersunk groove, and the nut is fixed with the countersunk groove by an interference fit. After connecting the first hinge part 113 and the second hinge part 211, the screw is passed through the second channel 212, the first channel 1131, and the third channel 213 and then screwed to the nut for fixation. It is understood that in other embodiments, the first rotating shaft 22 can also be a straight cylindrical pin, which directly passes through the second channel 212, the first channel 1131, and the third channel 213, wherein the cylindrical pin has an interference fit with the first channel 1131 and a clearance fit with the second channel 212 and the third channel 213, or the cylindrical pin has a clearance fit with the first channel 1131 and an interference fit with the second channel 212 and the third channel 213.

[0035] In actual production, the first housing 11 and the first door panel 21 are usually made of plastic. This reduces heat exchange between the receiving cavity 111 and the outside environment, preventing the ice from melting too quickly, reducing energy consumption for refrigeration, and also reducing production costs. Therefore, directly setting the first protrusion 1141 on the first housing 11 and the second protrusion 241 on the first door panel 21 can lead to wear after repeated contact and crossing. To further extend the service life of the first protrusion 1141 and the second protrusion 241, and to enhance the rotational damping between the first door panel 21 and the first housing 11, metal parts can be added, and the first protrusion 1141 and the second protrusion 241 can be mounted on metal parts, extending their service life and improving the rotational feel.

[0036] In some embodiments, please refer to Figures 5 to 7 The main body 10 includes a first damping element 114, which is fixed to a first channel 1131. A first rotating shaft 22 passes through the interior of the first damping element 114 and is rotatable relative to the first damping element 114. The first damping element 114 has a first protrusion 1141 at its end in the first direction X. The door assembly 20 includes a second damping element 24, which is fixed to a first door panel 21 and rotates synchronously with it. The first rotating shaft 22 passes through the second damping element 24 and is rotatable relative to it. The second damping element 24 has a second protrusion 241 on its side in the first direction X, and the first protrusion 1141 and the second protrusion 241 are opposite to each other. As an example, the first damping element 114 and the second damping element 24 can be made of metal or alloy.

[0037] It is understandable that when the first protrusion 1141 is disposed on the first damping member 114, the first protrusion 1141 divides the first damping member 114 into the first stroke 114a and the second stroke 114b in the first direction X.

[0038] In some embodiments, please refer to Figure 5The first damping member 114 is provided with a first limiting part 1142, and the first hinge part 113 is provided with a second limiting part 1132. The first limiting part 1142 and the second limiting part 1132 are connected to each other, so that the first damping member 114 is fixed to the first hinge part 113 in the circumferential direction. The first rotating shaft 22 passes through the inside of the first damping member 114, which allows the first rotating shaft 22 to rotate relative to the first damping member 114. This converts the friction between the first rotating shaft 22 and the inner wall surface of the first channel 1131 into friction between the first rotating shaft 22 and the inner wall surface of the first damping member 114, reducing the wear of the first hinge part 113 and extending its service life. At the same time, the first damping member 114, which is made of metal or alloy, is easier to process. The cooperation between the first rotating shaft 22 and the first damping member 114 can improve their coaxiality, which helps to improve the smoothness of the rotation of the first door panel 21.

[0039] As an example, the first limiting portion 1142 is a groove, and the second limiting portion 1132 is a protrusion. When the first damping member 114 is assembled into the first channel 1131, the protrusion and the groove are connected to each other to fix the first damping member 114 in the circumferential direction. Of course, in other examples, the first limiting portion 1142 may be a protrusion and the second limiting portion 1132 may be a groove.

[0040] In some embodiments, please refer to Figures 6 to 8 The second damping member 24 is provided with a third limiting part 242, and the first door panel 21 is provided with a fourth limiting part 2111. The third limiting part 242 and the fourth limiting part 2111 are connected in a cooperating manner. The second damping member 24 is fixed to the first door panel 21 in the circumferential direction so that the second damping member 24 and the first door panel 21 rotate synchronously. When the first door panel 21 rotates relative to the first housing 11, the first damping member 114 and the second damping member 24 also rotate relative to each other, making their movement more stable. As an example, the third limiting part 242 is an extension that extends in a direction away from the second protrusion 241. The fourth limiting part 2111 is a insertion groove. When the second damping member 24 is connected to the first door panel 21, the extension is inserted into the insertion groove to fix the second damping member 24 relative to the first door panel 21 in the circumferential direction.

[0041] It is worth noting that, in addition to the above-mentioned method of setting a limiting part, the fixed connection between the first damping member 114 and the first hinge part 113, and the fixed connection between the second damping member 24 and the first door panel 21 in this embodiment of the application can also be achieved through fastening connection, glue bonding, interference fit connection, and other connection methods.

[0042] In some embodiments, please refer to Figure 7 and Figure 8The door assembly 20 includes an elastic member 25. Along a first direction X, the elastic member 25 abuts against the sidewall of the second damping member 24 and the second hinge portion 211. The elastic member 25 is configured to provide a force to the second damping member 24 in the first direction X, so that the second damping member 24 remains in contact with the first damping member 114. For details, please refer to [further details omitted]. Figure 6 During the relative rotation of the second protrusion 241 of the second damping member 24 in the first stroke 114a and the second stroke 114b of the first damping member 114, the distance between the first damping member 114 and the second damping member 24 in the first direction X remains basically unchanged. However, during the process of the second protrusion 241 of the second damping member 24 abutting against and passing over the first protrusion 1141 of the first damping member 114, the distance between the first damping member 114 and the second damping member 24 in the first direction X increases. Since the first damping member 114 is fixed to the first hinge portion 113 with a sleeve structure, the second... Since the damping element 114 hardly produces any displacement, by placing the elastic element 25 on the side of the second damping element 24 away from the first damping element 114, the elastic element 25 can absorb and buffer the displacement of the second damping element 24 in the first direction X, and support the second damping element 24. After the second protrusion 241 crosses the first protrusion 1141, it provides a force to the second damping element 24, causing the second damping element 24 to move closer to the first damping element 114, so that the first door panel 21 has a jerky movement, thereby allowing the user to have a clear jerky tactile sensation.

[0043] In some embodiments, please refer to Figure 1 The main body 10 includes a first magnetic chuck 12, which is disposed on the first housing 11. The first magnetic chuck 12 and the first hinge portion 113 are located on adjacent sides of the opening 112. The door assembly 20 includes a second magnetic chuck 26, which is disposed on the first door panel 21. The position of the second magnetic chuck 26 corresponds to the position of the first magnetic chuck 12, and the second magnetic chuck 26 and the first magnetic chuck 12 can attract each other, so that the first door panel 21 is fixed relative to the first housing 11 when the opening 112 is closed. As an example, one of the first magnetic chuck 12 and the second magnetic chuck 26 may be a magnet, and the other may be a magnetic material, such as an iron sheet, or both may be magnets. In other embodiments, the first magnetic chuck 12 and the first hinge portion 113 may be located on opposite sides of the opening 112.

[0044] In some embodiments, please refer to Figure 1The door assembly 20 includes a second door panel 27, which is spaced apart from the first door panel 21 on the side away from the receiving cavity 111. The second door panel 27 covers the second hinge portion 211. By providing the second door panel 27 on the outside of the first door panel 21, the second hinge portion 211 and the second magnetic member 26 on the first door panel 21 can be concealed, improving the aesthetics of the door assembly 20. In addition, the first door panel 21 and the second door panel 27 are spaced apart, and the space between them is filled with a heat insulation layer 28, which can further reduce the heat exchange between the receiving cavity 111 and the outside, ensuring the refrigeration effect inside the receiving cavity 111.

The main body 10 has a receiving cavity 111 and an opening 112, the opening 112 connecting the receiving cavity 111 to the outside. The main body 10 has a first hinge portion 113, and the first hinge portion 113 has a first protrusion 1141. The door assembly 20 has a second hinge portion 211, which is rotatably connected to the first hinge portion 113. The door assembly 20 is configured to open or close the opening 112. The second hinge portion 211 has a second protrusion 241, which is configured to abut against and cross the first protrusion 1141, causing the door assembly 20 to produce a tactile feedback.
