[0040] This embodiment provides a water distribution valve, as Figure 1 - Figure 2As shown in the figure, the water distribution valve includes a housing 100 and a water distribution plate 200. A water distribution cavity 110 is provided inside the housing 100. An inlet 111 and at least two outlets 112 are provided on the side wall of the water distribution cavity 110. The water distribution plate 200 is rotatably arranged in the water distribution cavity 110. The water distribution plate 200 and the housing 100 can jointly enclose a water passage 113. The water passage 113 can connect the inlet 111 with at least one outlet 112, enabling the water flow to smoothly flow from the inlet 111 to at least one outlet 112, reducing the resistance when the water flow passes through the water distribution valve and reducing the loss of water pressure. Moreover, compared with the method of blocking the outlet 112 to achieve water path switching, when the water distribution valve switches the water path, the path that the water distribution plate 200 needs to rotate is short, thereby reducing the water path switching time and improving the working efficiency of the water distribution valve.

[0041] Optionally, as Figure 2 shown, the water distribution plate 200 includes a rotating shaft 220, a first plate body 210 and a second plate body 230. The rotating shaft 220 is rotatably arranged on the bottom wall of the water distribution cavity 110. The first plate body 210 and the second plate body 230 are arranged at an angle α on the rotating shaft 220. One end of the first plate body 210 away from the rotating shaft 220 is slidably connected to the side wall of the water distribution cavity 110, and one end of the second plate body 230 away from the rotating shaft 220 is slidably connected to the side wall of the water distribution cavity 110, thereby ensuring that the water distribution plate 200 can accurately control the direction of the water flow and ensuring that the water flow can be smoothly and efficiently distributed to each spray arm. In this embodiment, the water distribution plate 200 is integrally formed, simplifying the manufacturing process of the water distribution plate 200 and improving the manufacturing efficiency of the water distribution plate 200.

[0042] Optionally, the angle α is greater than or equal to 150° and less than 180°. Specifically, the angle α can be 150°, 155°, 160°, 165°, 170°, 175°. In this embodiment, it is preferably that the angle α between the first plate body 210 and the second plate body 230 is 150°, so that the water distribution plate 200 can more smoothly control the water flow direction during rotation, while reducing the impact force of the water flow, further reducing the water flow resistance and water pressure loss.

[0043] Optionally, reinforcing ribs are respectively provided at the joints of the first plate body 210 and the second plate body 230 with the rotating shaft 220. The reinforcing ribs can effectively improve the structural strength of the joints, prevent the water distribution plate 200 from deforming or breaking under the action of high-pressure water flow, and improve the durability and stability of the water distribution valve.

[0044] Specifically, as Figure 3 - Figure 5 shown, in this embodiment, three outlets 112 are provided on the side wall of the water distribution cavity 110. The three outlets 112 are defined as a first outlet 1121, a second outlet 1122 and a third outlet 1123 respectively. The water distribution valve includes three working modes:

[0045] In the first working mode, the water dividing piece 200 rotates to the position as shown in Figure 3 the figure. The water passing channel 113 can connect the water inlet 111 with the first water outlet 1121 to supply water to the spray arm connected to the first water outlet 1121. In this mode, the water flow can focus on cleaning a specific area to ensure better cleaning effect.

[0046] In the second working mode, the water dividing piece 200 rotates to the position as shown in Figure 4 the figure. The water passing channel 113 can connect the water inlet 111 with the second water outlet 1122 to supply water to the spray arm connected to the second water outlet 1122. In this mode, the water flow can cover another specific area to provide a flexible cleaning solution.

[0047] In the third working mode, the water dividing piece 200 rotates to the position as shown in Figure 5 the figure. The water passing channel 113 can connect the water inlet 111 with the second water outlet 1122 and the third water outlet 1123 simultaneously to supply water to the two spray arms connected to the second water outlet 1122 and the third water outlet 1123 at the same time. In this mode, the water flow can cover a larger area at the same time, improving the cleaning efficiency and coverage area.

[0048] Optionally, a water inlet connection part is provided at the water inlet 111, and a first water outlet connection part, a second water outlet connection part and a third water outlet connection part are respectively provided at the first water outlet 1121, the second water outlet 1122 and the third water outlet 1123. Such a design facilitates the connection of the water dividing valve with the water inlet waterway and the water outlet waterway, making the installation and disassembly of the water dividing valve more convenient, reducing the installation time and complexity, and improving the assembly efficiency of the water dividing valve.

[0049] Optionally, the water dividing valve further includes a driving part 300. The driving part 300 is in transmission connection with the water dividing piece 200, and the driving part 300 can drive the water dividing piece 200 to rotate so as to switch the waterway.

[0050] Optionally, the driving part 300 includes a driving motor. The driving motor is in transmission connection with the water dividing piece 200, and the driving motor can accurately control the rotation angle of the water dividing piece 200 to ensure the accuracy of the waterway switching, reduce the errors and instability caused by manual operation, and improve the working efficiency and performance of the water dividing valve.

[0051] Optionally, the drive motor is communicatively connected to the controller. The controller can intelligently adjust the rotation angle of the water diverter 200 according to the working state and cleaning requirements of the dishwasher, so as to achieve the best water flow distribution and cleaning effect. Among them, the controller can be a centralized or distributed controller. For example, the controller can be a single microcontroller, or can be composed of multiple distributed microcontrollers. A control program can run in the microcontroller, and then drive the drive motor to drive the water diverter 200 to rotate. The connection circuit between the controller and the drive motor, and the control program running in the controller are technical means well-known to those skilled in the art, and will not be elaborated here.

[0052] Optionally, the water diversion valve further includes a transmission assembly. The input end of the transmission assembly is drivingly connected to the output end of the driving member 300, and the output end of the transmission assembly is drivingly connected to the water diverter 200. Specifically, the transmission assembly includes a first gear and a second gear. The first gear is coaxially fixed to the output shaft of the drive motor, and the second gear is coaxially fixed to the rotating shaft 220 of the water diverter 200. The first gear and the second gear are meshed, so as to transmit the power of the drive motor to the water diverter 200. By providing the transmission assembly, the drive motor can be arranged at a reasonable position, making the internal structure of the dishwasher more compact and improving the utilization rate of the internal space of the dishwasher.
