Description

Technical Field

[0001] The present application relates to the technical field of ice-making devices, and in particular to an ice-removing motor fixing device, an ice-making device and a refrigerator. Background Art

[0002] Existing ice-making devices use an ice tray to hold liquid. After the liquid solidifies in a low-temperature environment, a motor is used to drive the ice tray to flip or twist it, causing the ice cubes to fall out of the tray. When the motor drives the ice tray, the resistance of the ice tray causes the motor's torque output shaft to generate a reaction force on the motor, which can easily push the motor out of the ice tray bracket, causing the ice-making device to fail.

[0003] Furthermore, existing ice-making devices typically require additional fixings for the motor housing within the ice tray bracket to ensure the stability of the motor's mounting structure. To ensure structural reliability, these fixings are typically rigid structures to ensure strength. Furthermore, the motor's mounting orientation and torque direction must be specifically configured to position and secure the motor using a rigid, immovable mounting structure.

[0004] Such a structure typically requires a special design for the motor's mounting channel, utilizing internal bends to counteract the motor's reaction force. This requires significant installation space within the ice tray bracket and requires the motor to be moved and adjusted at specific angles to ensure stable installation within the ice-making device. This structure struggles to adapt to the demands of more integrated assemblies, resulting in a loss of ice tray capacity. The complex assembly process can lead to errors, reduced assembly efficiency, and the risk of failure during use. Summary of the Invention

[0024] To make the purpose and technical solutions of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and, unless defined as such herein, will not be interpreted in an idealized or overly formal sense.

[0026] The meaning of "and / or" in this application means that both situations where each exists alone or both exist at the same time are included.

[0027] The meaning of "inside" and "outside" in this application refers to the direction pointing to the motor accommodation position inside the ice tray bracket relative to the ice tray bracket itself, and the opposite direction is outside; it is not a specific limitation on the device mechanism of this application.

[0028] The meaning of "left" and "right" in this application refers to that when the user is facing the ice tray holder, the user's left is the left and the user's right is the right, rather than a specific limitation on the device mechanism of this application.

[0029] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.

[0030] The meaning of "up" and "down" in this application refers to that when the user is facing the ice tray bracket, the direction in which the motor is installed along the ice tray bracket is down, and the direction in which the motor is removed from the ice tray bracket is up, rather than a specific limitation on the device mechanism of this application.

[0031] In the present application, when the ice tray receives liquid to make ice, the opening direction of the ice tray or the direction of taking out ice cubes can be set to be opposite to the installation direction of the motor or can be set to be the same as the installation direction of the motor according to the running direction of the motor.

[0032] Figure 1 An ice-making device according to the present application is provided in a refrigerator and includes:

[0033] The ice tray 4 is used to receive liquid for cooling and ice making;

[0034] The ice tray bracket 10 has an ice removal motor housing 3 mounted on one side and an ice tray 4 mounted on the other side;

[0035] The de-icing motor housing 3 houses a motor and a corresponding transmission system, which is used to output torque through the torque output shaft located in the middle thereof, driving the ice tray 4 to flip or deform, causing the ice cubes inside to fall out. The motor also drives the ice probe 5 connected to its side to probe into the frozen area of ​​the ice tray to determine the condensation status of the ice cubes.

[0036] The ice tray support 10 of the present application is provided with a movable ice-removing motor fixing device.

[0037] The de-icing motor fixing device includes Figure 1 Shown:

[0038] Torque resistant ribs 1 are respectively provided on three adjacent inner walls of the ice tray support 10. When installed, the torque resistant ribs 1 are fixedly connected to the deicing motor housing 3 to resist the torque acting on the deicing motor housing 3 during the ice tray flipping process;

[0039] Also includes Figure 2 Shown:

[0040] The non-rigid movable portion 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, the non-rigid movable portion 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 present application can directly install and fix the motor housing into the motor receiving cavity in the ice tray support 10 by a straight-up and straight-down plug-in method.

[0043] This application utilizes torque-resistance ribs 1, located on the sidewalls of the ice tray support's ice-removing motor housing, to abut the motor housing from three sides. These ribs limit the tilting torque exerted on the motor housing by the ice tray's reaction force, directly bearing the majority of the stress and preventing the motor from tilting within the ice tray support's cavity due to the ice tray's reaction force. As a result, the non-rigid movable portion 2 only needs to bear minimal stress, limiting the motor's installation height while maintaining a secure motor structure.

[0044] Generally speaking, the ice maker can flexibly set the water receiving direction of the ice box structure, for example, Figure 1 The illustrated configuration allows the ice box to receive liquid from the bottom of the ice tray holder, which the motor abuts after assembly. In this state, after the motor is installed on the base plate, the entire ice-making unit needs to be flipped and secured in the refrigerator. The motor's torque output shaft drives the motor's rotation, while the motor's bottom is secured by the non-rigid movable portion 2, providing support against gravity and preventing the motor from falling. After ice making is complete, the motor's output drives the ice box to flip, which reacts to the motor, using the locking action of the non-rigid movable portion 2 to bring the motor closer to the bottom of its mounting cavity.

[0045] In other implementations, the opening direction of the ice box of the ice maker can also be aligned with the opening direction of the motor housing. In this case, the motor's tilting caused by the reaction of the ice box is also supported by the torque-resisting rib 1. In this embodiment, the non-rigid movable portion 2 also only needs to bear a small amount of stress, and the installation height of the motor can be limited to prevent it from rising out of the motor housing.

[0046] Regardless of the orientation of the ice tray, in this application, the deicing motor housing 3 can be installed in a direction perpendicular to the direction of the reaction torque of the ice tray 4 on the deicing motor. That is, the reaction force of the ice tray 4 on the deicing motor rotates along the vertical plane of the front end of the motor, and the motor installation direction is perpendicular to the normal direction of this rotating plane.

[0047] For a more specific implementation, refer to Figure 3As shown, the present application can connect one side of each of the torque-countering ribs 1 to the inner wall surface of the ice tray bracket 10, set the extension length of the torque-countering rib 1 into the motor mounting cavity, and limit the other side of each of the torque-countering ribs 1 to be fixed against the outer surface of the de-icing motor housing 3.

[0048] To ensure the motor housing is effectively restrained, the present application preferably provides two parallel torque-resistance ribs 1 extending upward from the bottom of the ice tray holder on each side of the inner wall of the cavity of the ice tray holder 10. For inner walls with limited installation space, the present application may also add a transverse reinforcement rib extending upward from the bottom of the ice tray holder and parallel to the de-icing motor housing on the side of the torque-resistance rib 1 closest to the motor to enhance the structural strength of the torque-resistance rib 1 and prevent it from twisting due to the reaction force of the motor.

[0049] Generally speaking, in order to keep the force on the motor symmetrical, the present application generally arranges the non-rigid movable part 2 on both sides of the de-icing motor torque output direction. Figure 2 The method shown is set on the left and right sides of the torque output shaft in the connection area between the motor and the ice box, or on the left and right sides of the side wall of the motor back close to the installation cavity and away from the ice box, or can be set respectively Figure 1 The middle inspection ice rod 31 and the lower position on its opposite side.

[0050] The non-rigid movable part 2 can be implemented using a cantilever structure. The cantilever can be directly integrated with the ice tray bracket, and the toughness of the ice tray bracket structure itself is used to realize an elastic cantilever. The elastic cantilever extends from the side wall of the ice tray bracket to the bottom of the bracket, bends inward at the free end of the cantilever and extends to the installation path of the de-icing motor housing 3. The bottom here is only for the installation direction of the motor: in the motor installation cavity, on the side of the end point of the motor plug-in direction, it is defined here as the bottom of the motor installation cavity. The bottom of the motor installation cavity here can be set to be in the same direction or opposite to the bottom of the ice tray that receives the liquid, or it can point to the side wall of the ice tray in a sideways-mounted motor structure.

[0051] refer to Figure 3 As shown, the non-rigid movable portion 2 may be specifically configured to include:

[0052] A hook 21 is bent inward from the side wall of the ice tray support and extends toward the bottom. The distal end of the hook is bent toward the output direction of the de-icing motor torque and extends close to the upper portion of the stop claw 22.

[0053] The stop claw 22 extends from the bottom of the ice tray bracket toward the hook 21. A height difference is set between the top of the stop claw 22 and the bottom of the end of the hook 21. The height difference is close to the thickness of the connecting portion 32 extending toward the ice tray at the bottom of the ice removal motor housing 3.

[0054] As a result, the bottom of the hook 21 and the top of the stop pawl 22 can respectively abut the upper and lower sides of the connecting portion 32 provided on the bottom of the de-icing motor housing 3, which extends toward the ice tray. This limits the motor's installation height within the bracket's mounting cavity. This keeps the motor in place, and during motor rotation, the torque antagonist rib 1 transmits the motor's reaction torque, maintaining the motor at its installed height with minimal stress, preventing the motor from separating from the ice tray bracket's opening in the direction of its mounting cavity.

[0055] To facilitate motor assembly, the present application further preferably includes guide ribs extending from the side of the hook 21 toward its bottom. The guide ribs smoothly transition from the sidewall of the hook 21 to the innermost bottom edge of the stop pawl 22. The guide ribs can be parallel to the installation path of the de-icing motor housing 3. The guide ribs can gradually narrow upward from the innermost bottom edge of the hook 21 until they completely conform to the sidewall of the hook 21.

[0056] As a result, during the downward installation of the motor, the connecting portion 32 on the bottom side of the motor moves downward along the guide ribs, pushing the hook 21 outward toward the side wall of the ice tray holder 10. When the bottom surface of the connecting portion 32 reaches the top of the stop pawl 22, the hook 21 breaks free from the contact with the side surface of the connecting portion 32 and, due to its elastic potential energy, rebounds inward to its original position before expansion. In this position, the bottom of the hook 21 abuts the top surface of the connecting portion 32, preventing the motor from moving away in the direction of its installation.

[0057] Generally speaking, the connecting portion 32 on the de-icing motor housing is typically located in the mounting plane of the torque output shaft, at the bottom of the motor housing in the direction of assembly. To maintain balanced force, the connecting portion 32 is typically positioned symmetrically with the torque output shaft, extending toward the ice tray. When installed, the connecting portion 32 is locked within the travel range of the non-rigid movable portion 2, exerting only minimal stress on the hook 21 or the pawl 22, primarily maintaining the motor at a height close to the bottom of its mounting slot.

[0058] In order to further prevent the motor from flipping under force, the present application can 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 tray and works together with the torque counteracting rib 1 to limit the motor from flipping.

[0059] A side wall can be provided on one side of the stopper 22. The side wall has a top portion extending upward from the stopper, connected to the outside of the positioning plate, and extending toward the ice tray to the end of the stopper. The connecting portion 32 at the bottom of the deicing motor housing 3 is supported by the stopper 22 below the hook 21. The side wall, which connects the stopper 22 to the motor positioning plate, provides guidance for the inner sidewall of the connecting portion 32 in the installation direction and prevents the connecting portion 32 from tilting relative to the ice tray bracket 10 and disengaging from the bottom of the motor mounting cavity after assembly.

[0060] In the present application, the stop claw 22 and the hook 21 are both configured to be integrally formed with the ice tray bracket 10, and the toughness of the ice tray bracket material itself can be used to provide corresponding elasticity to stabilize the motor and prevent it from being subjected to force and moving out of the installation position from the opening.

[0061] In summary, the present invention utilizes the locking claw 22 and hook 21 to clamp the connection portion of the motor housing, and in conjunction with the torque-resisting rib 1, it absorbs the majority of the reaction force from the motor's tilting force. This allows for direct insertion and simultaneous positioning of the motor using a simple, lightweight, and movable structure. This streamlined structure facilitates assembly and is easy to implement. It not only effectively reduces the space occupied by the motor's mounting structure and the overall size of the ice-making device, but also further enhances the stability of the motor assembly, ensuring stable operation of the ice-making device.

[0062] The above is only an embodiment of the present application, and its description is relatively specific and detailed, but it should not be understood as limiting the scope of the patent application. It should be pointed out that for those skilled in the art, various modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
