That is to say, when the water system 100 is working, the turbidity of the water in the accommodating chamber can be detected by the turbidity sensor 11 to control the water tank 30 to automatically collect the water that meets the recycling conditions, so as to achieve the purpose of saving water. Here, the water collected by the water tank 30 is clean water that can be used for other purposes.

[0040] like Figure 1 As shown, in one embodiment, the water system 100 further includes a drain valve 12, which is installed on the water cup 10 and is used to discharge the water in the accommodating cavity to the connecting cavity 21. That is to say, when the water system 100 is working, the drain valve 12 is used to control the drainage of the water in the accommodating cavity of the water cup 10, so that the drainage of the water from the water cup 10 to the connecting cavity 21 can be controlled. It should be noted that the specific structure of the drain valve 12 and the working principle of how to control the drainage of the water from the water cup 10 to the connecting cavity 21 during operation can all adopt existing conventional methods, which will not be elaborated here.

[0041] like Figure 2 , Figure 3As shown, in one embodiment, the connecting cavity 21 is configured as a three-way structure 211, the three-way structure 211 has an inlet 2111, a first outlet 2112 and a second outlet 2113, the inlet 2111 is connected to the first outlet 2112 and forms a first channel 201, the inlet 2111 is connected to the second outlet 2113 and forms a second channel 202; wherein the inlet 2111 is connected to the accommodating cavity, and the first outlet 2112 is connected to the water tank 30.

[0042] It can be understood that the connection cavity 21 is configured as a three-way structure 211. In this way, on the basis of satisfying that the connection cavity 21 has two flow paths, the structure of the connection cavity 21 is simplified.

[0043] like Figure 3 As shown, in one embodiment, the control assembly 22 includes a valve block 221, a transmission rod 222 and a driving member 223.

[0050] like Figure 1 , Figure 4 As shown, in one embodiment, the water system 100 further includes a drainage pump 50, which is disposed on the bottom wall 32 of the water tank 30 and is connected and communicated with the water tank 30, and the drainage pump 50 can pump out the water in the water tank 30. When the water system 100 is working, the drainage pump 50 is used to drain the water from the water tank 30, so that the water in the water tank 30 can be drained regularly to prevent the water in the water tank 30 from becoming smelly due to long-term non-use.

[0051] In addition, the present application also provides a dishwasher, including an inner tank 200 and the water system 100 described above; wherein the water cup 10 is connected and communicated with the inner tank 200, so that during the washing process of the dishwasher, the inner tank can be discharged into the water cup 10, and then the turbidity sensor 11 detects whether the turbidity of the water in the cavity of the water cup 10 meets the recycling requirements, and controls the water tank 30 to automatically collect the water that meets the recycling requirements. It should be noted that the water control mechanism 20 and the water tank 30 in the water system 100 can be arranged outside the dishwasher according to the use requirements.

[0052] In summary, the water system 100 of the present application uses a turbidity sensor 11 to determine the turbidity of water in the water storage chamber, and then uses a control component 22 to control the flow path of water discharged from the water cup 10, so that when the water system 100 is working, the water tank 30 can automatically collect water that meets the recycling conditions, thereby achieving the purpose of saving water.
