[0025] like Figure 4 As shown, the dish rack assembly 100 for which protection is claimed in this utility model is used in a dishwasher 1000 for placing tableware inside the dishwasher.

[0026] like Figures 1 to 3 As shown, the bowl basket assembly 100 provided by this utility model includes a fixed bowl basket 10, a movable bowl basket 20, a threaded shaft 30, a clutch 40, and a rotary drive component 50. The fixed bowl basket 10 includes a fixed bowl support 11. The movable bowl basket 20 is movably mounted on the fixed bowl basket 10 and includes a movable bowl support 21. The threaded shaft 30 is screwed to the movable bowl basket 20. The clutch 40 includes a driving component 41 and a driven component 42. The driven component 42 is driven by the threaded shaft 30 and can engage / disengage with the driving component 41 under the drive of the threaded shaft 30.

[0027] As can be seen from the above, the bowl basket assembly 100 of this utility model utilizes the threaded engagement between the threaded shaft 30 and the movable bowl basket 20, enabling the bowl basket assembly 100 to continuously and infinitely adjust the installation position of the movable bowl basket 20 on the fixed bowl basket 10 by controlling the rotation drive component 50. This allows the bowl basket assembly 100 to intelligently and accurately adapt to tableware of different sizes, depths, and shapes. In this way, it not only improves the convenience and flexibility of users in placing tableware and avoids obstruction and overlap caused by improper placement, but also ensures that the washing water flow and spray coverage are thorough by optimizing the gaps between tableware, which is conducive to improving the final cleanliness of the tableware.

[0028] It should be noted that the bowl basket assembly 100 of this utility model can be adapted to accommodate tableware of different sizes, depths and shapes by adjusting the misalignment distance between the movable bowl support 21 on the movable bowl basket 20 and the fixed bowl support 11 on the fixed bowl basket 10.

[0029] like Figure 1 , Figure 2 As shown, in one embodiment, the number of fixed bowl supports 11 on the fixed bowl basket 10 and the number of movable bowl supports 21 on the movable bowl basket 20 are both set to multiple rows. The multiple rows of fixed bowl supports 11 correspond one-to-one with the multiple rows of movable bowl supports 21, and the fixed bowl supports 11 are disposed on one side of the corresponding movable bowl supports 21 in the width direction X of the dishwasher 1000, so that the bowl basket assembly 100 can carry tableware through the mutual cooperation between the fixed bowl supports 11 and the movable bowl supports 21.

[0030] Here, multiple rows of movable bowl supports 21 are arranged sequentially at intervals along the width direction X of the dishwasher 1000. The spacing between adjacent rows of movable bowl supports 21 can be specifically set according to actual needs, which will not be elaborated here.

[0031] like Figure 2 , Figure 3 As shown, in one embodiment, the movable bowl basket 20 further includes a connecting rod 22, which is slidably connected to the fixed bowl basket 10. One end of the movable bowl support 21 is connected to the connecting rod 22. Furthermore, the threaded shaft 30 is screwed to the connecting rod 22, so that the threaded shaft 30 can drive the movable bowl support 21 to slide on the fixed bowl basket 10 through the connecting rod 22, and achieve consistency in direction when the movable bowl basket 20 moves on the fixed bowl basket 10.

[0032] Here, as Figure 3As shown, one end of the movable bowl support 21 is bent to form a bent portion 211, and the bent portion 211 is embedded in the connecting rod 22, thereby realizing the assembly connection between the movable bowl support 21 and the connecting rod 22. It can be understood that in other embodiments, the movable bowl support 21 can also be connected to the connecting rod 22 by welding, which will not be elaborated here.

[0033] like Figure 3 As shown, in this embodiment, the connecting rod 22 is provided with a slot 222, which is snapped onto the main rod 12 of the fixed basket 10. The connecting rod 22 can slide on the main rod 12 through the slot 222, thereby realizing a sliding connection between the connecting rod 22 and the fixed basket 10.

[0034] As shown in the figure, in this embodiment, the movable bowl basket 20 also includes a cooperating link 23. The cooperating link 23 is disposed at the other end of the movable bowl support 21 and is connected to multiple rows of movable bowl supports 21 respectively, so that the multiple rows of movable bowl supports 21 of the movable bowl basket 20 are fixed by the link 22 and the cooperating link 23 respectively, thereby improving the overall structural strength of the movable bowl basket 20.

[0035] like Figure 3 As shown, in one embodiment, the connecting rod 22 has a threaded hole 221; correspondingly, the threaded shaft 30 has a threaded portion 31, which passes through the threaded hole 221 and is screwed into it; furthermore, the thread length of the threaded portion 31 is greater than the thread length of the threaded hole 221. This allows the connecting rod 22 to move back and forth on the threaded portion 31 during rotation, utilizing the threaded engagement between the threaded portion 31 and the threaded hole 221, thereby adjusting the installation position of the movable basket 20 on the fixed basket 10.

[0036] like Figure 3 As shown, in one embodiment, the driven component 42 can be plugged into the driving component 41. When the driven component 42 is plugged into the driving component 41, the driven component 42 and the driving component 41 mesh with each other, so that the driven component 42 and the driving component 41 are connected. This can establish a clear and reliable power transmission point between the driving component 41 and the driven component 42, thereby significantly enhancing the stability and reliability of the power transmission process between the driving component 41 and the driven component 42.

[0037] like Figure 3 As shown, in one embodiment, the driven member 42 and the threaded shaft 30 are connected by a connecting joint 401; wherein, the threaded shaft 30 is partially inserted into the connecting joint 401 and connected to the connecting joint 401, specifically by a screw thread that passes through the driven member 42 and is connected to the threaded shaft 30, thereby locking the threaded shaft 30 into the connecting joint 401.

[0038] In one embodiment, the rotary drive 50 is configured as a servo motor, stepper motor, etc.

[0039] In addition, this utility model also provides a dishwasher 1000, which includes the dish rack assembly 100 described above.

[0040] like Figure 4 As shown, in one embodiment, the dishwasher 1000 further includes a dishwasher inner tub 200, with both the fixed dish rack 10 and the movable dish rack 20 housed within it. The driving component 41 of the clutch 40 penetrates the dishwasher inner tub 200 and is sealed to it. A rotary drive component 50 is disposed on the outside of the dishwasher inner tub 200. This design ensures that when the dish rack assembly 100 is installed in the dishwasher 1000, water from the dishwasher inner tub 200 during dishwashing will not affect the rotary drive component 50. Therefore, the configuration of the rotary drive component 50 does not require consideration of waterproofing, thereby reducing the production cost of the rotary drive component 50.

[0041] In one embodiment, the dishwasher 1000 also includes a control switch (not shown), which is electrically connected to the rotary drive 50 and is used to control the opening / closing of the rotary drive 50. Thus, when the user needs to adjust the installation position of the movable dish rack 20 on the fixed dish rack 10, they only need to operate the control switch and send a command to the rotary drive 50, which drives the threaded shaft 30 to rotate via the clutch 40. This allows for stepless adjustment of the gap between the movable bowl support 21 on the movable dish rack 20 and the fixed bowl support 11 on the fixed dish rack 10, accommodating the placement of different tableware.

[0042] Here, the user can adjust the distance between the movable bowl support 21 and the fixed bowl support 11 according to the duration of the control switch trigger, thus achieving stepless adjustment of the distance between the fixed bowl support 11 and the movable bowl support 21. Of course, the control program for the control switch to operate the rotating drive component 50 can also have a memory module, allowing the user to input a memory program based on their family's tableware usage habits for one-click automatic adjustment. Alternatively, in other embodiments, the control switch can also have an intelligent voice control module, including a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, which are then parsed by the voice parsing module. Based on the parsed commands, the controller controls the rotating drive component 50 to perform corresponding operations, thereby achieving intelligent control of the rotating drive component 50 and improving the user experience of using this smart appliance. Further details will not be elaborated here.

[0043] It should be noted that the dishwasher 1000 of this utility model utilizes the clutch design of the clutch 40, which can meet the user's need to pull the fixed dish rack 10 and the movable dish rack 20 out with the drawer. In this way, when it is necessary to adjust the distance between the movable dish support 21 and the fixed dish support 11, it is only necessary to push the fixed dish rack 10 and the movable dish rack 20 into the dishwasher inner tub 200 with the drawer and then trigger the control switch. There is no need to bend over and operate manually, making the operation simple and convenient.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
