[0008] As a preferred embodiment, the bottom of the sludge collecting groove is provided with a first inclined surface and a first flat surface, a first side of the first inclined surface is connected with the side wall of the sludge collecting groove, a second side of the first inclined surface is connected with the first flat surface, the height of the first side of the first inclined surface is higher than that of the first flat surface, the connection between the first inclined surface and the first flat surface is smoothly transitioned through an arc surface, the first water outlet and the mounting hole are arranged on one side of the first inclined surface, and the first drain hole is arranged on one side of the first flat surface.

[0009] The first inclined surface plays a guiding role, so that the impurities in the sump fall along the first inclined surface to the first plane under the action of gravity and are concentrated on the first plane. The first drain is arranged on one side of the first plane to facilitate the discharge of impurities. When the water flows along the first inclined surface, local turbulent flow is generated, which enhances the carrying capacity of suspended particles and prevents impurities from depositing on the first inclined surface. The connection between the first inclined surface and the first plane is smoothly transitioned through the arc surface, which can eliminate the right-angle dead angle and avoid impurities being stuck in the dead angle, so that the impurities can smoothly slide from the first inclined surface to the first plane and then be discharged from the first drain. The first water outlet is arranged on one side of the first inclined surface, so that the circulating water and the impurities are effectively separated in space to prevent the impurities from entering the water distribution chamber. The mounting hole is arranged on one side of the first inclined surface, so that the turbidity sensor avoids the area where the impurities are located, thereby ensuring the accuracy of detection.

Such arrangement can reduce the local water flow speed and pressure when the circulating water enters the water distribution cavity, so that the water flow is more stable, and the noise and vibration caused by water flow impact when the circulating water enters the water distribution cavity can be reduced.

[0016] As a preferred embodiment, the bottom of the water distribution cavity is provided with a second water outlet, and the inner side of the second water outlet is provided with a sealing ring. The second water outlet is used to connect the inner water pipe and / or the spray arm.

[0017] As a preferred embodiment, the first drain port is connected with a drainage assembly, and the drainage assembly includes a drainage pipeline and a drainage pump. The drainage pipeline and the first drain port are respectively connected with the drainage pump.

[0018] Compared with the prior art, the first drain port is arranged in the dirt collecting tank, and impurities are deposited at the bottom of the dirt collecting tank under the action of gravity, so that the impurities can be conveniently collected and discharged from the first drain port when the impurities are deposited to a certain amount. The installation port is located above the dirt collecting tank, so that the turbidity sensor is prevented from being interfered by the impurities in the dirt collecting tank, the turbidity of the water in the water collecting cavity can be more accurately detected, and meanwhile, the turbidity sensor can be prevented from being damaged due to being wrapped by impurities such as food residues and oil stains, so that the service life is prolonged.
