The installation and working principle is as follows (two water outlets are taken as an example for explanation):

referring to fig. 1, 3 and 5, the water diversion valve assembly is fixedly connected with a water cup 11 through a snap structure and sealed through a sealing ring 10 (as shown in fig. 2). The structure is arranged on a mounting seat 7 through a driving motor 8 and is fixed on an end cover 2 through a fastener 9, and a driving shaft 8.1 of the driving motor penetrates through a D-shaped groove 5.2 on a driving gear 5. The driving gear 5 is meshed with the transmission gear 4, and the positioning teeth 4.3 arranged on the transmission gear 4 are matched with the positioning grooves 5.1 of the driving gear 5 to realize the matching and positioning of the gears.

The edge of the driving gear 5 is provided with a plurality of contacts, including a long contact 5.3 and a short contact 5.4, the contacts can trigger the on-off of the micro switch in the rotating process so as to obtain a potential signal, so that the rotating position is judged, and the duration of the potential signal obtained by triggering the long contact 5.3 and the short contact 5.4 is different, so that the initial position can be judged.

The mode that this structure realized dividing water is: the end cover 2 is connected with the water cup 11 to form a sealed water distribution cavity 2.1, the shifting sheet 1 is of a plane structure, and the water distribution cavity 2.1 can be flattened, so that the volume of the water distribution cavity 2.1 is reduced, and the water consumption is reduced. One end of the water distribution cavity 2.1 is connected with the water inlet 12, the other end is provided with at least two water outlets (a first water outlet 13 and a second water outlet 14) arranged on the water cup, and each water outlet is provided with one or more cylindrical holes in a vertical upward direction. After water enters the water distribution cavity 2.1 from the water inlet 12, the water outlet can be closed through the rotation of the seeding piece 1. When the motor rotates, the extended driving shaft 8.1 penetrates through the D-shaped groove 5.2 of the driving gear 5 to drive the driving gear 5 to rotate, the transmission gear 4 meshed with the driving gear rotates together, and the shifting piece 1 inserted on the transmission gear 4 synchronously rotates. The contact (5.3/5.4) at the edge of the driving gear 5 triggers the microswitch 6 during rotation.

When the dish-washing machine is started, the driving motor 8 is controlled to rotate, when the long contact 5.3 triggers the microswitch 6, the system judges that the dish-washing machine is in an initial state (as shown in a state a in figure 4), at the moment, the plectrum 1 does not block any water outlet, and water can be discharged from both water outlets; when the system controls the driving motor 8 to rotate to the short contact 5.4 to trigger the microswitch 6, the shifting sheet 1 rotates to the position 1 (as shown in a state b in fig. 4), at the moment, two cylindrical holes of the water outlet II 14 are blocked, water cannot flow out, and only the water outlet I13 can flow out; when the system control motor continues to rotate and the microswitch 6 is triggered by the next short contact 5.4, the shifting piece 1 rotates to the position 2 (as shown in a state c in fig. 4), at the moment, the first water outlet 13 and the second water outlet 14 are both blocked by the shifting piece 1, and water can not flow out from the two water outlets; when the driving motor 8 continues to rotate and the microswitch 6 is triggered by the next short contact 5.4, the shifting piece 1 rotates to the position 3 (as shown in a state d in fig. 4), at the moment, the first water outlet 13 is blocked, water cannot be discharged, and only the second water outlet 14 can discharge water. When the driving motor rotates again, the long contact 5.3 starts the micro switch 6, and the shifting piece 1 returns to the initial position. Because the edge contact of the driving gear 5 and the shifting piece 1 are in 180-degree axial symmetry, the water distribution work of two circulations of the water distribution valve can be completed by rotating for a circle (360 degrees), and the time of the water distribution process is saved.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
