[0034] Reference Figure 1-Figure 3In one embodiment of the present invention, a dishwasher basket 11 drive device includes: a housing 1, wherein the housing 1 has the basket 11 disposed therein; a sliding assembly 2, including a fixed portion 21 and a sliding portion 22, wherein the sliding portion 22 is embedded in the fixed portion 21 and fixedly connected to the basket 11; a first driving assembly including a fixing portion 41 and a swinging arm portion 42, wherein the fixing portion 41 is connected to the inner wall of the housing 1, and the swinging arm portion 42 is rotatably connected to the fixing portion 41 via a hinge point provided thereon; a first driving assembly including a fixing plate 31 and a first driving portion, wherein one side of the fixing plate 31 is fixedly connected to the basket 11 and the other side is connected to the first driving portion; and a second driving assembly, wherein an output shaft of the second driving assembly is hingedly connected to the swinging arm portion 42, wherein after the first driving assembly drives the basket 11 to move along the sliding assembly 2 in the first direction, the second driving assembly drives the swinging arm assembly to rotate about the hinge point of the swinging arm portion 42 to adjust the vertical height of the basket 11.

[0035] In this embodiment, the combination of the sliding assembly 2 and the swing arm assembly enables flexible movement of the basket 11 in different directions (horizontally and vertically). The sliding assembly 2 provides stable horizontal movement of the basket 11, while the swing arm assembly and the second drive assembly work together to enable vertical and / or diagonal movement of the basket 11, significantly increasing the flexibility and versatility of the dishwashing process. Specifically, the first drive assembly, connected to the basket 11 via the fixed plate 31, linearly drives the basket 11 on the sliding assembly 2. When the first drive unit is activated, it drives the fixed plate 31 and the connected basket 11 along the sliding portion 22 of the sliding assembly 2, thereby achieving horizontal (i.e., first) displacement of the basket 11. Simultaneously, the hinged connection between the output shaft of the second drive assembly and the swing arm 42 enables the swing arm assembly to rotate about the output shaft. When the second drive assembly is activated, it moves forward along the output shaft, pushing the swing arm 42 to rotate about its hinge point. This connection between the swing arm assembly and the basket 11 allows the vertical height of the basket 11 to be adjusted, either diagonally or vertically. This design not only simplifies the dishwasher's drive structure and improves operational stability, but also reduces user operation complexity and labor through automated control. Furthermore, since the basket 11 can move in different directions, the user can lift it, eliminating the need for users with limited mobility to bend over to retrieve dishes, thus enhancing the user experience.

[0036] It's worth noting that in this embodiment, the first and second drive assemblies are activated sequentially to achieve orderly bidirectional movement of the basket 11. First, the first drive assembly activates, driving the basket 11 horizontally to a preset position. Then, the second drive assembly activates, rotating the swing arm assembly, which in turn drives the basket 11 vertically and / or diagonally upward to adjust its vertical height. This sequential activation design ensures stability and safety during basket 11 movement, avoiding conflicting or unstable movements caused by simultaneous operation of the two drive assemblies. In addition to the basic functions described above, the dishwasher basket 11 drive mechanism of this embodiment offers several other advantages and features. The design of the sliding assembly 2 and the swing arm assembly ensures smoother movement of the basket 11, reducing the risk of damage to dishes caused by collision or friction. Furthermore, through automated control, the user can achieve bidirectional movement of the basket 11 with simple operations, significantly improving convenience. Finally, the drive mechanism's compact design occupies minimal space, contributing to a more aesthetically pleasing dishwasher.

[0037] In one embodiment, the swing arm portion 42 is further provided with a fixing post 421 and a guide post 422. The fixing plate 31 is provided with a fixing groove 311 corresponding to the fixing post 421 and a guide groove 312 corresponding to the guide post 422. The fixing groove 311 is used to allow the bowl basket 11 to move in the vertical direction and then cooperate with the fixing post 421 for fixation. The guide groove 312 is used to guide the movement of the guide post 422 when the bowl basket 11 moves in the vertical direction.

[0038] In this embodiment, the provision of fixing posts 421 and guide posts 422 on the swing arm 42, along with corresponding fixing slots 311 and guide slots 312 on the fixing plate 31, further enhances the stability and reliability of the basket 11 during vertical and / or diagonal upward movement. When the second drive assembly is activated, rotating the swing arm 42 about its hinge point, driving the basket 11 vertically, the fixing posts 421 gradually engage with the fixing slots 311, ensuring stable positioning of the basket 11 after movement. Simultaneously, the movement of the guide posts 422 within the guide slots 312 guides the movement of the swing arm 42 and basket 11, ensuring that the basket 11 reaches its target position smoothly and accurately. This design not only improves dishwasher safety but also enhances the user's dishwashing experience.

[0039] In one embodiment, the swing arm 42 is further provided with a stop block 423. When the first drive assembly drives the basket 11 to move in the first direction, the stop block 423 abuts against the guide post 422. A pressure detection element is provided at one end of the stop block 423 corresponding to the guide post 422 to detect changes in pressure between the stop block 423 and the guide post 422.

[0040] In this embodiment, a stop block 423 is provided on the swing arm 42, and a pressure sensing element is provided at the end of the stop block 423 corresponding to the guide post 422. During operation, the dishwasher provides real-time detection and feedback of the movement status of the basket 11, thereby ensuring a safe and smooth dishwashing process. Specifically, when the first drive assembly drives the basket 11 along the sliding assembly 2 in the first direction (horizontally), the stop block 423 abuts the guide post 422, causing a change in pressure between the stop block 423 and the guide post 422. This pressure change is quickly captured by the pressure sensing element and converted into an electrical signal. This signal is then processed by the dishwasher's control system, indicating that the basket 11 has reached a predetermined horizontal position. The second drive assembly is then activated to drive the basket 11 vertically and / or diagonally upward, completing the entire drive process.

[0041] refer to Figure 2 In one embodiment, the first driving portion includes a fixed block 321 and a first driving member 322, one end of the first driving member 322 is connected to the inner wall of the shell 1, and the other end abuts against the fixed block 321, and the fixed block 321 is connected to the fixed plate 31.

[0042] In this embodiment, the first driving member 322 abuts the inner wall of the housing 1, pushing the fixing block 321 and thereby moving the basket 11 in the first direction. Specifically, the first driving member 322 propels the fixing block 321 along a predetermined track or path. The fixing block 321 is tightly connected to the fixing plate 31. Therefore, when the fixing block 321 moves, the fixing plate 31 and its connected basket 11 also move synchronously, ensuring stable horizontal movement of the basket 11.

[0043] It is worth noting that the drive members (first drive member 322, second drive member 331, and third drive member 332) of the present application can adopt a variety of drive methods, such as motors, electric cylinders, hydraulic cylinders, etc., and the selection can be based on the specific needs and actual conditions of the dishwasher. Different drive methods can meet different driving needs and scenarios, thereby improving the flexibility and adaptability of the dishwasher.

[0044] In one embodiment, the second driving assembly includes a second driving member 331 and a third driving member 332. The side surface of the second driving member 331 is connected to the reference portion 41. The output shaft of the second driving member 331 is hinged to the swing arm portion 42. The output shaft of the third driving member 332 is connected to the side surface of the output shaft of the second driving member 331. The second driving member 331 and the third driving member 332 both move forward along their corresponding output shafts, driving the swing arm assembly to rotate around the hinge point between the output shaft of the second driving member 331 and the swing arm portion 42 to adjust the vertical height of the bowl basket 11.

[0045] In this embodiment, the second drive assembly utilizes a dual-driver design: a second driver 331 and a third driver 332. These two drivers work in tandem to achieve stable and precise rotational control of the swing arm assembly. Specifically, the side of the second driver 331 is connected to the reference portion 41, while its output shaft is hingedly connected to the swing arm portion 42, forming a pivot point for rotation. Simultaneously, the output shaft of the third driver 332 is connected to the side of the output shaft of the second driver 331. This design allows both drivers to jointly apply torque to the swing arm portion 42, ensuring stability and accuracy during rotation. When the second and third drivers 331 and 332 are activated simultaneously, they move forward along their respective output shafts, driving the swing arm assembly to rotate about its hinge point. Because both drivers act simultaneously, they provide a stable rotational torque to the swing arm assembly, avoiding rotational instability or deviation caused by insufficient power from a single driver. This design not only improves the dishwasher's operating efficiency but also ensures precision and stability during vertical and / or diagonal movement of the basket 11. In another embodiment, during actual operation, a single drive component may fail due to various reasons (such as aging or wear of the drive component). In this case, the remaining functioning drive component can still maintain the rotation of the swing arm assembly, thereby moving the basket 11 vertically and / or diagonally upward. This fault-tolerant design improves the reliability and stability of the dishwasher, providing users with a safer and more reliable dishwashing experience.

[0046] In one embodiment, a triggering portion 5 is further included. The triggering portion 5 is connected to the bowl basket 11 and is used to trigger the first driving member 322 to start.

[0047] In this embodiment, the trigger unit 5 is located at the front of the basket 11, where the user pulls the basket 11. When the user needs to pull the basket 11 out of the dishwasher or push it in, they simply pull or push it. The trigger unit 5 senses this action and immediately sends a signal to the dishwasher's control system. Upon receiving the signal, the control system quickly responds by activating the first drive member 322, which drives the fixing block 321 to move the fixing plate 31 and the basket 11 in the first direction (horizontally). This design not only enhances the dishwasher's intelligence but also greatly improves user convenience.

[0048] In another embodiment, this trigger mechanism also features an anti-accidental activation feature. When the dishwasher is operating normally, trigger unit 5 is locked, preventing user error that could cause the dishwasher to stop operating or basket 11 to be accidentally moved. Only when manual operation of basket 11 is required can the user unlock and activate the trigger mechanism through a specific action (such as long-pressing trigger unit 5), ensuring safe and stable operation of the dishwasher.

[0049] It's worth noting that the trigger unit 5 in this embodiment can function through a direct connection between the basket 11 and the first drive member 322, or through indirect induction. In the case of a direct connection, the trigger unit 5 can be a mechanical switch or button. When the user pushes or pulls the basket 11, this switch or button is directly contacted, thereby activating the first drive member 322. In the case of indirect induction, the trigger unit 5 can be an inductive sensor that detects changes in the position of the basket 11 or the user's intended movement and sends a signal to the control system, thereby triggering the activation of the first drive member 322. This can be achieved by electrically connecting the trigger unit 5 to the first drive assembly through the basket 11. Specifically, if the basket 11 is made of metal, when the basket 11 moves, its metal portion contacts the circuitry in the first drive assembly, triggering an electrical signal and activating the first drive member 322. This electrical connection not only ensures accurate and stable signal transmission, but also improves the reliability and durability of the trigger mechanism.

[0050] refer to Figure 3 In one embodiment, the housing 1 includes a bottom plate 6 having a groove 61 formed in the middle thereof. The groove 61 includes a main groove 611 and side grooves 612. The side grooves 612 extend along the edges of the main groove 611, and the main groove 611 is deeper than the side grooves 612. The housing 1 also includes a drain port and a water inlet. The drain port is disposed within the main groove 611, and the water inlet is located on the side wall of the housing 1.

[0051] In this embodiment, the recess 61 on the bottom plate 6 not only provides space for the basket 11 to move, but also enhances the dishwasher's drainage and water intake performance through its unique structure. The main groove 611 serves as the primary drainage channel. Its deep design allows for rapid drainage of accumulated water, preventing water accumulation within the dishwasher. Side grooves 612 extend along the edges of the main groove 611, providing guidance and positioning for the basket 11, ensuring stability and accuracy during movement. Furthermore, the shallow design of the side grooves 612 prevents water accumulation and enhances the robustness and stability of the outer shell 1. A drain port is located within the main groove 611, facilitating the direct discharge of accumulated water, reducing resistance during drainage and improving drainage efficiency. The water inlet is located on the side wall of the outer shell 1. This design not only facilitates connection to a water pipe but also avoids interference between the water inlet and drain port, ensuring smooth and stable water intake. Furthermore, the location of the water inlet takes into account the overall structure and aesthetics of the dishwasher, resulting in a high-quality dishwasher in both appearance and performance.

[0052] In one embodiment, a control module is further included, which is electrically connected to the first drive assembly and the second drive assembly and is used to control the start and stop of the first drive assembly and the second drive assembly.

[0053] In this embodiment, the control module serves as the dishwasher's core component, responsible for coordinating and managing all of its functions. Through electrical connections with the first and second drive assemblies, the control module precisely controls the start, stop, and operating states of these two drive assemblies, ensuring the dishwasher operates according to pre-set procedures and steps. Specifically, the control module flexibly adjusts the operating parameters of the first and second drive assemblies, such as speed and operating time, based on the dishwasher's various operating modes and user needs, enabling precise movement of the basket 11 in various directions.
