Abstract
Description
Technical Field
[0001] This application relates to the field of ice-making equipment technology, and more specifically to an ice-removing motor fixing device, an ice-making device, and a refrigerator. Background Technology
[0002] Existing ice-making devices use an ice tray to collect liquid. After the liquid solidifies in a low-temperature environment, a motor drives the ice tray to rotate or twist, causing the ice to detach. During the process of the motor driving the ice tray, the motor's torque output shaft will generate a reaction force on the motor due to the resistance of the ice tray. This can easily cause the motor to be pushed out of the ice tray support, resulting in the failure of the ice-making device.
[0003] Furthermore, existing ice-making devices typically require additional fixing devices for the motor housing within the ice tray support to ensure the stability of the motor's mounting structure. To ensure structural reliability, these fixing devices generally need to be rigid to guarantee structural strength. Moreover, further special settings are required for the installation direction of the motor fixing structure and the direction of the motor torque to utilize the rigid, immovable fixing structure for positioning and securing the motor.
[0004] Such a structure typically requires a special design for the motor mounting channel, utilizing internal bends to counteract the reaction force on the motor. This structure occupies considerable installation space within the ice tray support and necessitates pushing and repositioning the motor at specific angles to ensure stable installation within the ice-making device. This design struggles to meet the demands of more integrated assembly, reduces the ice tray's ice-making capacity, is prone to errors due to the complex assembly process, reduces assembly efficiency, and increases the risk of malfunctions during use. Utility Model Content
[0005] This application addresses the shortcomings of existing technologies by providing an ice-removing motor fixing device, an ice-making device, and a refrigerator. The ice tray support features torque-resisting ribs on its three inner walls to provide structural strength. These ribs, along with a non-rigid movable part extending inwards from the ice tray support, provide positioning for the ice-removing motor. The flexible space of the non-rigid movable part allows for a direct-insertion assembly channel, simplifying the assembly process of the ice-making device, simplifying the internal installation structure of the ice tray support, ensuring reliable motor fixing, and reducing the overall size of the ice-removing motor fixing device, thus improving the integration of the ice-making device. The specific technical solution adopted in this application is as follows.
[0006] First, to achieve the above objectives, a de-icing motor fixing device is proposed, which is installed in an ice tray support and includes: torque-resisting ribs, which are respectively installed on the inner walls of three adjacent sides of the ice tray support.

During installation, the housing of the de-icing motor is pressed down to the bottom of the ice tray support along the channel formed by the torque-resisting ribs. During the pressing process, the housing of the de-icing motor pushes the non-rigid movable part to expand outward to form an installation channel.

[0009] Optionally, in any of the above-described de-icing motor fixing devices, the non-rigid movable part includes: a hook that bends inward from the side wall of the ice tray support and extends to the bottom, the end of the hook bending in the direction of the de-icing motor torque output and extending close to the upper part of the stop claw; the stop claw extending from the bottom of the ice tray support towards the hook, a height difference being provided between the top of the stop claw and the bottom of the end of the hook, the height difference being close to the thickness of the connecting part extending towards the ice tray at the bottom of the de-icing motor housing.
[0010] Optionally, in any of the above-described de-icing motor fixing devices, the hook is further provided with a guide rib parallel to the installation path of the de-icing motor housing between its bottom-extending side wall and the bottom end bent to the stop claw; the guide rib gradually narrows in width from the bottom end of the hook upwards until it completely fits the side wall plane of the hook.
[0011] Meanwhile, to achieve the above objectives, this application also provides an ice-making device, which includes: an ice tray support, on one side of which an ice-removing motor housing is installed, and on the other side of which an ice tray is installed; an ice-removing motor fixing device as described above is provided between the ice tray and the ice tray support; wherein, the installation direction of the ice-removing motor housing is perpendicular to the direction of the reaction torque of the ice tray on the ice-removing motor.
[0012] Optionally, in any of the ice-making devices described above, a torque output shaft is provided on one side of the de-icing motor housing, and a connecting part extending toward the ice tray is also provided at the bottom of that side of the de-icing motor housing. In the installed state, the connecting part is locked within the stroke range of the non-rigid moving part.
[0013] Optionally, in any of the ice-making devices described above, during the pressing installation process, the connecting part moves down along the guide rib and pushes the hook outward toward the side wall of the ice tray support. When the bottom surface of the connecting part reaches the top of the stop claw, the hook springs back inward and abuts against the top surface of the connecting part.

[0015] In addition, to achieve the above objectives, this application also provides a refrigerator in which an ice-making device as described in any of the above descriptions is provided.
[0016] Beneficial effects
[0017] The ice-removing motor fixing device, ice-making device, and refrigerator provided in this application overcome the technical bias of traditional ice-making device motor fixing devices. The conventional design replaces the rigid, non-deformable locking structure that fixes the motor housing with a non-rigid, elastically movable free end. This application optimizes the stress and ice tray support structure, using torque-resistant ribs to limit the rotation of the motor structure caused by the reaction force of the ice tray. This, combined with the non-rigid movable part forming a free end with an elastically movable range, provides positioning for the motor structure. This application directly fixes the ice-removing motor using movable parts. On the one hand, it allows for direct insertion of the motor, simplifying the assembly process of the ice-making device; on the other hand, it reduces the installation space required by the motor fixing mechanism, further reducing the overall size of the ice-making device and improving its integration. The device structure of this application is streamlined, adaptable to refrigerators with higher integration requirements, and simplifies assembly operations while ensuring structural strength, thus improving system reliability.

Detailed Implementation
[0024] To make the objectives and technical solutions of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.
[0025] Those skilled in the art will understand that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless defined as herein.
[0026] The meaning of "and / or" as used in this application includes situations where each exists alone or both exist simultaneously.
[0027] In this application, "inner" and "outer" refer to directions relative to the ice tray support itself, with the direction pointing towards the motor housing inside the ice tray support being "inner" and the opposite being "outer"; rather than being a specific limitation on the device mechanism of this application.
[0028] The terms "left" and "right" as used in this application refer to the user's left side as the left and the user's right side as the right when the user is facing the ice tray support, and do not constitute a specific limitation on the device mechanism of this application.
[0029] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.
[0030] The terms "up" and "down" as used in this application refer to the direction in which the motor is installed along the ice tray support when the user is facing the ice tray support, and the direction in which the motor is removed from the ice tray support, and are not specific limitations on the device mechanism of this application.
[0031] In this application, when the ice tray receives liquid to make ice, the opening direction of the ice tray or the direction in which the ice is taken out can be set to be opposite to the installation direction of the motor, or it can be set to be the same as the installation direction of the motor according to the rotation direction of the motor.
[0032] Figure 1 An ice-making apparatus according to this application, disposed in a refrigerator, includes:
[0033] Ice tray 4 is used to receive liquid for cooling and ice making;
[0034] An ice tray support 10 has an ice-removing motor housing 3 installed on one side and an ice tray 4 installed on the other side.
[0035] The de-icing motor housing 3 houses the motor and the corresponding transmission system, which outputs torque through the torque output shaft located in the middle to drive the ice disk 4 to flip or deform, causing the ice inside to fall out. The motor also drives the ice probe 5 connected to its side to probe into the icing area of the ice disk to determine the freezing status of the ice.
[0036] The ice tray support 10 of this application is equipped with a movable ice-removing motor fixing device.
[0037] The de-icing motor fixing device includes Figure 1 Shown:
[0038] Torque counteracting ribs 1 are respectively installed on the inner walls of three adjacent sides of the ice tray support 10. In the installed state, the torque counteracting ribs 1 are fixedly connected to the ice removal motor housing 3 to counteract the torque acting on the ice removal motor housing 3 during the ice tray flipping process.
[0039] Also includes Figure 2 Shown:
[0040] The non-rigid moving part 2 extends inward from the inner wall of the ice tray support 10.
[0041] refer to Figure 1During installation, the de-icing motor housing 3 is pressed down to the bottom of the ice tray bracket 10 along the channel formed by the torque-resisting ribs 1. During the pressing process, the de-icing motor housing 3 pushes the non-rigid movable part 2 to expand outward to form an installation channel.
[0042] When the motor is installed in place, the non-rigid movable part 2 automatically returns to its original position before expansion when the de-icing motor housing 3 reaches the bottom of the ice tray support, and is locked in the installation path of the de-icing motor housing 3. Based on this structure, the motor housing can be directly installed and fixed into the motor receiving cavity inside the ice tray support 10 by a straight up-down plug-in method.
[0043] This application utilizes torque-resisting ribs 1, which abut against the motor housing from three sides, on the sidewalls of the ice tray support's ice-removing motor housing. These ribs limit the overturning torque generated by the ice box's reaction force on the motor housing, directly bearing most of the stress and preventing the motor from overturning within the ice tray support's cavity due to the ice tray's reaction force. Therefore, the non-rigid moving part 2 only needs to bear a smaller stress, and limiting the motor's installation height is sufficient to fix the motor structure.
[0044] Generally speaking, ice makers allow for flexible settings of the water inlet direction in the ice container structure; for example, refer to... Figure 1 As shown, the ice box receives liquid from the bottom of the ice tray support after the motor is assembled. In this state, after the motor is installed on the base plate, the entire ice-making device needs to be flipped and fixed in the refrigerator. The motor's torque output shaft drives the motor to flip, and the bottom of the motor is locked by the non-rigid movable part 2, providing support against gravity and preventing the motor from falling. After ice making is complete, the motor output drives the ice box to flip, and the ice box reacts to the motor, using the locking action of the non-rigid movable part 2 to bring the motor closer to the bottom of its mounting cavity.
[0045] In other implementations, the opening direction of the ice box in the ice maker can also be consistent with the opening direction of the motor's receiving cavity. In this case, the rotation of the motor caused by the reaction force of the ice box is also borne by the torque counterweight 1. In this method, the non-rigid moving part 2 only needs to bear a small stress, which is enough to limit the installation height of the motor so that it does not detach from the motor receiving cavity.
[0046] Regardless of the assembly orientation of the ice tray, in this application, the mounting direction of the de-icing motor housing 3 can be set perpendicular to the direction of the reaction torque of the ice tray 4 on the de-icing motor. That is, the reaction force of the ice tray 4 on the de-icing motor rotates along the vertical plane of the front end face of the motor, and the mounting direction of the motor is perpendicular to the normal direction of this rotation plane.
[0047] For a more specific implementation, refer to Figure 3As shown, this application can connect one side of each of the torque counteracting ribs 1 to the inner wall surface of the ice tray support 10, set the extension length of the torque counteracting ribs 1 into the motor mounting cavity, and limit the other side of each of the torque counteracting ribs 1 to abut and fix to the outer surface of the de-icing motor housing 3.
[0048] To ensure effective restraint of the motor housing, this application preferably provides two parallel torque-resisting ribs 1 extending upwards from the bottom of the ice tray support on each side of the inner wall of the cavity of the ice tray support 10. For inner walls with limited installation space, this application may also add a transverse reinforcing rib extending upwards from the bottom of the ice tray support and parallel to the ice-removing motor housing on the side of the torque-resisting rib 1 closest to the motor, in order to improve the structural strength of the torque-resisting rib 1 and prevent it from twisting under the reaction force of the motor.
[0049] Generally, to maintain symmetrical force distribution on the motor, this application typically arranges the non-rigid moving parts 2 on both sides of the torque output direction of the de-icing motor. For example, using... Figure 2 The torque output shaft is positioned as shown in the diagram on the left and right sides of the connection area between the motor and the ice box, or on the left and right sides of the motor's back side, close to the mounting cavity and away from the ice box's side wall. Alternatively, it can be positioned separately on each side. Figure 1 The ice rod 31 and its lower side.
[0050] The non-rigid movable part 2 can be implemented using a cantilever structure. This cantilever can be directly integrally formed with the ice tray support, utilizing the inherent toughness of the ice tray support structure to achieve an elastic cantilever. The elastic cantilever extends from the side wall of the ice tray support towards the bottom of the support, bending inward at its free end and extending into the installation path of the de-icing motor housing 3. Here, "bottom" refers only to the motor's installation direction: within the motor's mounting cavity, the side located at the endpoint of the motor's insertion direction is defined here as the bottom of the motor mounting cavity. The bottom of the motor mounting cavity can be set to face the same direction or opposite direction as the bottom of the ice tray that receives the liquid, or in a side-mounted motor structure, it can point towards the side wall of the ice tray.
[0051] refer to Figure 3 As shown, the aforementioned non-rigid moving part 2 can specifically be configured to include:
[0052] Hook 21, which bends inward from the side wall of the ice tray support and extends to the bottom, with the end of the hook bending in the direction of the output torque of the de-icing motor and extending close to the upper part of the stop pawl 22.
[0053] The stop claw 22 extends from the bottom of the ice tray support towards the hook 21. There is a height difference between the top of the stop claw 22 and the bottom of the hook 21. The height difference is close to the thickness of the connecting part 32 extending towards the ice tray at the bottom of the de-icing motor housing 3.
[0054] Therefore, the bottom of the hook 21 and the top of the stop 22 can respectively abut against the upper and lower sides of the connecting part 32 extending towards the ice tray at the bottom of the de-icing motor housing 3, limiting the installation height of the motor within the bracket mounting cavity. This keeps the motor in a suitable position, and during motor rotation, the torque counter-torque rib 1 transmits the reaction torque to the motor, maintaining the motor at its installation height position with minimal stress, preventing the motor from detaching from the ice tray bracket from the opening of its mounting cavity.
[0055] To facilitate the insertion and assembly of the motor, this application further preferably provides a guide rib extending towards the bottom of the hook 21 on its side. The guide rib smoothly transitions from the side wall of the hook 21 to the innermost bottom end of the stop 22. The guide rib can be parallel to the installation path direction of the de-icing motor housing 3. The guide rib can gradually narrow its width from the innermost bottom end of the hook 21 upwards until it completely fits the side wall plane of the hook 21.
[0056] Therefore, during the downward installation of the motor, the connecting part 32 on the bottom side of the motor moves down along the guide rib and pushes the hook 21 outward toward the side wall of the ice tray support 10. When the bottom surface of the connecting part 32 reaches the top of the stop pawl 22, the hook 21 disengages from the side contact of the connecting part 32 and rebounds inward to its original position before outward expansion due to the influence of elastic potential energy. In this position, the bottom contact limit of the hook 21 is located on the top surface of the connecting part 32, restricting the motor from being withdrawn along its installation direction.
[0057] Generally, the connecting portion 32 on the de-icing motor housing is usually located in the mounting plane of the torque output shaft, at the bottom of the motor housing assembly direction. To maintain balanced force distribution, the connecting portions 32 are typically configured to extend symmetrically towards the ice tray direction relative to the torque output shaft. In the installed state, the connecting portion 32 is engaged within the stroke range of the non-rigid moving part 2, generating only minor stress on the hook 21 or the stop pawl 22, primarily used to maintain the motor at a height close to the bottom of its mounting slot.
[0058] To further prevent the motor from overturning under force, this application may further provide a positioning plate extending from the bottom of the motor mounting cavity toward the torque output shaft at the bottom of the ice tray bracket 10 between the de-icing motor housing 3 and the ice tray, according to the assembly position of the motor. The positioning plate is locked between the motor and the ice box and together with the torque counter-rib 1, it restricts the motor from overturning.
[0059] A sidewall may be provided on one side of the stop claw 22, with the top of the stop claw extending upwards and connecting to the outside of the positioning plate, extending towards the ice tray to the end of the stop claw. The connecting part 32 at the bottom of the de-icing motor housing 3 is supported by the stop claw 22 at the lower part of the hook 21, and the sidewall connecting the stop claw 22 to the motor positioning plate provides a guide for the installation direction of the inner sidewall of the connecting part 32, and after assembly, prevents the connecting part 32 from flipping relative to the ice tray bracket 10 and disengaging from the bottom of the motor mounting cavity.
[0060] In this application, both the stop claw 22 and the hook 21 are integrally formed with the ice tray bracket 10. The toughness of the ice tray bracket material itself can provide corresponding elasticity to stabilize the motor and prevent it from being dislodged from the installation position due to force.
[0061] In summary, this application uses the stop pawl 22 and the hook 21 to clamp the connection part of the motor housing, and with the torque counter-rib 1 bearing most of the reaction force when the motor is subjected to force and flips, it can achieve the assembly of the motor in a simple and lightweight movable structure through a direct insertion method, while ensuring the motor is limited and fixed. This application has a simplified structure, is easy to assemble, and is easy to implement. It can not only effectively reduce the space occupied by the motor mounting structure and the overall size of the ice-making device, but also further improve the stability of the motor assembly and ensure the stable operation of the ice-making device.
[0062] The above are merely embodiments of this application, and their descriptions are quite specific and detailed, but they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
