[0031] See Figures 1-15 This is an embodiment of an adjustable foot for a dishwasher proposed in this invention. The adjustable foot is mounted on a base 200 and includes: a foot 10, an adjusting rod 20, an engaging structure 30, and a fixing block 40. The foot 10 is fixed to the base 200 of the dishwasher via a threaded connection. The adjusting rod 20 is arranged in a front-to-back direction and is used to adjust the height of the foot 10. The engaging structure 30 is located between the adjusting rod 20 and the foot 10, and is used to transmit the rotational movement of the adjusting rod 20 to the foot 10 to achieve vertical adjustment. A receiving groove 201 is provided on the base 200 to receive the engaging structure 30; a fixing block 40 is provided at the rear open end of the receiving groove 201, and the fixing block 40 is positioned behind the engaging structure 30.

[0032] In this embodiment, the foot 10 is adjusted using the adjusting rod 20. This allows for adjustment of the rear foot 10 from the front without changing the dishwasher's position, even after the dishwasher is connected to water and electricity and pushed into the cabinet. This effectively solves the installation difficulty problem, reduces installation complexity, and improves installation efficiency. The engagement structure 30 stably transmits the rotational movement of the adjusting rod 20 to the foot 10, enabling vertical adjustment of the foot 10 and accurately adjusting its height. The fixing block 40 at the rear open end of the receiving groove 201 prevents the engagement structure 30 from moving backward, providing a limiting and fixing function, further enhancing the stability and reliability of the engagement structure 30. Installing the engagement structure 30 within the receiving groove 201 of the base 200 makes the entire adjustable foot structure more compact, occupying less external space and improving space utilization. For different models and specifications of dishwashers, it can be easily applied by appropriately adjusting the dimensions of components such as the adjusting rod 201 and the foot 10, demonstrating good versatility.

[0033] In some embodiments of this application, the meshing structure 30 includes a turbine 31 fixedly mounted to the adjusting rod 20 and a gear sleeve 32 sleeved on the outside of the base 10. The outer side of the gear sleeve 32 has external teeth that mesh with the turbine 31, and the inner side of the gear sleeve 32 has internal threads that match the base 10. When the adjusting rod 20 is rotated, the turbine 31 rotates accordingly. The turbine 31 meshes with the external teeth on the outer side of the gear sleeve 32, which can stably transmit the rotational motion of the adjusting rod 20 to the gear sleeve 32, thereby driving the base 10 to rotate relative to the gear sleeve 32, realizing the up and down movement of the base 10, and realizing the adjustment of the dishwasher height. The meshing of the turbine 31 and the gear sleeve 32 has a self-locking characteristic. When the dishwasher is adjusted to a suitable height, the base 10 will not easily rotate due to the weight of the dishwasher itself or other external forces when no external force is applied to the adjusting rod 20, thus keeping the dishwasher at the set height. The gear sleeve 32 is fitted onto the outside of the base 10, and the turbine 31 meshes with the gear sleeve 32. The meshing structure 30 has a compact layout, making efficient use of the space around the base 10. It does not require excessive additional space to achieve the adjustment function, making the overall structure of the dishwasher more compact. A precise correspondence is formed between the rotation angle of the adjusting rod 20 and the lifting height of the base 10, improving the accuracy of the dishwasher's height adjustment. The inner side of the gear sleeve 32 has an internal thread that matches the base 10. This threaded connection method makes the installation and removal of the gear sleeve 32 and the base 10 relatively convenient.

[0034] In some embodiments of this application, the gear sleeve 32 is rotatably located within the receiving groove 201; the turbine 31 is coaxially arranged with the adjusting rod 20, and the gear sleeve 32 is coaxially arranged with the base 10. The coaxial arrangement of the turbine 31 and the adjusting rod 20 ensures that the rotational movement of the adjusting rod 20 is transmitted to the turbine 31 without deviation, guaranteeing that the turbine 31 rotates synchronously with the adjusting rod 20. The coaxial arrangement of the gear sleeve 32 and the base 10 allows the gear sleeve 32 to precisely apply the power transmitted from the turbine 31 to the base 10, causing the base 10 to rotate up and down as expected, thereby achieving precise adjustment of the dishwasher height. The coaxial arrangement reduces additional friction and wear between components due to misalignment, making the entire adjustment system more stable during operation and reducing vibration and noise caused by misalignment. The rotatable location of the gear sleeve 32 within the receiving groove 201 utilizes the space inside the base 200, accommodating the gear sleeve 32 within a specific area, resulting in a more compact internal structure for the dishwasher.

[0035] In some embodiments of this application, the fixing block 40 is located on the rear side of the turbine 31. An interlocking extension edge structure is provided between the turbine 31 and the fixing block 40. The extension edge structure consists of a first extension edge 311 extending rearward on the turbine 31 and a second extension edge 41 fitted outside the first extension edge 311 on the fixing block 40. The interlocking of the first extension edge 311 and the second extension edge 41 provides additional support and positioning for the turbine 31. When the adjusting rod rotates and drives the turbine 31 to rotate, the turbine 31 will be subjected to certain axial and radial forces. The extension edge structure can effectively withstand these forces, preventing the turbine 31 from axially or radially shifting or wobbling, ensuring that the turbine 31 maintains a stable position during operation, making its rotation smoother, and improving the stability of the entire adjusting system.

[0036] In some other configurations of this application, the extension edge structure may also be provided with a first extension edge on the fixed block 40 and a second extension edge on the turbine 31.

[0037] In some embodiments of this application, the second extension edge 41 is connected to a radially inwardly extending inner edge 42. The inner edge 42 and the second extension edge 41 enclose a defining slot 43 for defining the first extension edge 311. The first extension edge 311 is relatively movable within the defining slot 43. The defining slot 43 precisely limits the first extension edge 311 of the turbine 31 and provides additional stability, ensuring that the axial and radial displacement of the turbine 31 is limited to a small range during rotation, thus ensuring that the movement trajectory of the turbine 31 is always in the ideal state of the design.

[0038] In some embodiments of this application, a threaded hole 202 matching the foot 10 is provided on the base 200, ensuring that the foot 10 can be securely installed on the base via a threaded connection. The middle part of the threaded hole 202 communicates with the receiving groove 201, so that the meshing structure in the foot 10 and the receiving groove 201 are spatially related, facilitating the tight connection of the foot's adjustment mechanism with the foot itself. An insertion hole 204 for the adjustment rod 20 to extend into is provided on the front groove wall of the receiving groove 201.

[0039] In some embodiments of this application, the rear end of the adjusting rod 20 is provided with an assembly head 25, and the turbine 31 is fixedly sleeved on the outside of the assembly head 25. The assembly head 25 has an assembly rod 251, and a turbine hole 312 matching the assembly rod 251 is opened on the turbine 31. The assembly head 25 also has a plurality of radially approachable assembly claws 252 located at the rear end of the assembly rod 251. The plurality of assembly claws 252 are in a radially approachable state when installed through the turbine hole. A turbine groove 313 is opened on the turbine 31 to connect with the turbine hole 312 and to match the assembly claws 252. The design of the assembly head 25 makes the installation of the turbine 31 more convenient. The assembly claws 252 are in a radially approachable state when passing through the turbine hole 312, so they can easily pass through the turbine hole 312 without additional complicated operations or tools. After the assembly claws 252 pass through the turbine hole 312 and enter the turbine groove 313, they can approach each other radially, allowing for better engagement with the turbine groove 313 and ensuring a secure fixation of the turbine 31 on the assembly head 25. The radial approach capability of the assembly claws 252 can accommodate dimensional tolerances and installation errors that may occur during manufacturing. Furthermore, the assembly claws 252 can adjust their position through elastic deformation, ensuring smooth installation and a stable connection, thus improving component compatibility and product yield.

[0040] In some embodiments of this application, the radial dimension of the rear end of the turbine groove 313 is larger than the radial dimension of the front end of the turbine groove 313. A limiting structure for circumferential positioning is provided between the arc-shaped groove wall of the turbine groove 313 and the assembly claw 252 in the front-rear direction. The limiting structure has a matching limiting groove 3131 and a limiting protrusion 2521. The matching limiting groove 3131 and the limiting protrusion 2521 can circumferentially limit the assembly claw 252 within the turbine groove 313; ensuring that no relative circumferential sliding occurs between the assembly claw 252 and the turbine 31 when the turbine 31 rotates with the adjusting rod 20, and ensuring that the rotational movement of the adjusting rod 20 can be accurately transmitted to the turbine 31. The limiting structure can ensure that the relative positional relationship between the turbine 31 and the assembly head 25 remains stable, avoiding the impact of the turbine 31's shaking or displacement on its meshing with the gear sleeve 32, and ensuring the stability of the meshing structure.

[0041] In some embodiments of this application, a groove 2511 is provided on the assembly rod 251, and a plurality of circumferentially spaced assembly claws 252 are provided at the rear open end of the groove 2511. This allows the assembly claws 252 to be integrated into the assembly rod 251 in an orderly and compact manner, providing reasonable arrangement space and installation position for the assembly claws 252, thereby improving the integration of components and space utilization. The circumferentially spaced assembly claws 252 can be evenly distributed around the assembly rod 251, and when they cooperate with the turbine groove 313 and the turbine hole 312, they can simultaneously bear the force at multiple positions, making the connection between the turbine 31 and the assembly head 25 more robust and stable.

[0042] In some embodiments of this application, the assembly head 25 has a limiting edge 253 located at the front end of the assembly rod 251 and extending radially outward. Multiple limiting blocks 2531, spaced circumferentially apart, are provided on the limiting edge 253, and the limiting blocks 2531 extend rearward. A limiting slot 314 extending radially outward along the turbine hole 312 is provided at the front end of the turbine 31, and the limiting edge 253 is located within the limiting slot 314. A limiting receiving groove 3141 matching the limiting blocks 2531 is provided on the rear wall of the limiting slot 314. The limiting blocks 2531 and the limiting receiving groove 3141 circumferentially limit the movement between the turbine 31 and the assembly head 25. When the adjusting rod 20 rotates, the turbine 31 will not slide circumferentially relative to the assembly head 25, ensuring that the rotational movement of the adjusting rod 20 can be accurately transmitted to the turbine 31.

[0043] In some embodiments of this application, the fixing block 40 is snapped into place at the rear end of the receiving groove 201. The fixing block 40 has a fixing body 45 and a snap-fit ​​foot 46 extending radially outward along the fixing body 45. A second extension edge 41 is connected to the fixing body 45, and an inner edge 42 is the inner side of the fixing body 45. A snap-fit ​​groove 203 communicating with the receiving groove 201 is provided on the base 200, and the snap-fit ​​groove 203 is matched and snapped into place with the snap-fit ​​foot 46. During installation, the matching structure of the snap-fit ​​foot 46 and the snap-fit ​​groove 203 facilitates the installation operation of the fixing block 40. The installer can insert the snap-fit ​​foot 46 according to the position of the snap-fit ​​groove 203 to quickly complete the installation of the fixing block 40.

[0044] In some embodiments of this application, the engaging foot 46 has an engaging body 461 connected to the fixing body 45, an engaging claw 462 engaging in the engaging groove 203, and an arc-shaped connecting portion 463 connecting the engaging claw 462 and the engaging body 461. A deformation space 464 is provided between the engaging claw 462 and the engaging body 461 for the engaging claw 462 to deform towards the engaging body 461. The deformation space 464 between the engaging claw 462 and the engaging body 461 allows the engaging claw 462 to deform towards the engaging body 461. When installing the fixing block 40, the engaging claw 462 can elastically deform through the deformation space 464, making it easier to enter the engaging groove 203 and improving installation convenience. The existence of the deformation space 464 gives the engaging structure a certain degree of adaptability, enabling it to accommodate manufacturing tolerances and assembly errors. The 462 locking claw has a certain elastic deformation capability, which can buffer some of the external force when subjected to impact or vibration during the operation of the dishwasher.

[0045] In some embodiments of this application, a protruding claw portion 4621 is provided on the side of the engaging claw 462 away from the engaging body 461. An engaging opening 2031 is formed on the groove wall of the engaging groove 203, and the front part of the engaging foot 46 extends into the engaging opening 2031, with the claw portion 4621 engaging with the front edge of the engaging opening 2031. When the engaging claw 462 engages into the engaging opening 2031, the claw portion 4621 and the edge of the engaging opening 2031 block each other, preventing the engaging claw 462 from dislodging from the engaging opening 2031 when subjected to external tension or vibration, thus ensuring the connection stability between the fixing block 40 and the base 200, and allowing the fixing block 40 to be more securely fixed to the rear end of the receiving groove 200.

[0046] In some embodiments of this application, the engaging claw 462 is provided with a rearwardly extending handle 4622. The handle 4622 extends rearward beyond the engaging groove 203 and can be used to release the engagement between the engaging claw 462 and the engaging groove 203. The handle 4622 facilitates the release of the engagement between the engaging claw 462 and the engaging groove 203. When it is necessary to disassemble the fixing block 40, maintenance personnel can operate the handle 4622 to apply appropriate external force to deform the engaging claw 462 towards the engaging body 461, thereby releasing the engagement without the need for additional tools or complex operations, reducing the difficulty and time cost of maintenance and disassembly.
