Here, the water flow guide surface connects the water outlet end and the water receiving end, and water at the water receiving end can be guided to the water outlet end by the inclined water flow guide surface.

According to the water diversion plate, the inclination angle of the water flow guide surface of the upstream water diversion plate is different from the inclination angle of the water flow guide surface of the downstream water diversion plate, so that when water flowing out of the water diversion holes passes through the water diversion plates of each group of water diversion plates, the flowing direction can be continuously changed, and the flowing direction is changed in sequence after passing through one water diversion plate, and the effect of delaying the water flow speed is effectively achieved.

In the embodiment of the disclosure, in each set of water diversion plates, the inclination angles of the water flow guiding surfaces of the two non-adjacent water diversion plates relative to the bottom wall of the water tank may be the same or different, and the disclosure is not limited thereto.

When one water diversion hole corresponds to one group of water diversion plates, after water flowing out of the water diversion holes flows to the water diversion plate at the most upstream of one row of water diversion plates, the water flow is transited by the water flow guiding surface of the water diversion plate at the most upstream, the water flow changes the flowing direction and flows to the water diversion plate at the downstream of the other row of water diversion plates, which is adjacent to the current water diversion plate in the upstream relation, at the moment, the water flow becomes the upstream water diversion plate, after the water flow transits and changes the direction through the water flow guiding surface of the water diversion plate, the water flow flows to the water diversion plate at the downstream of the water diversion plate, which is adjacent to the current water diversion plate in the downstream relation, and the water flow flows to the bottom wall of the water tank from the water diversion plate at the most downstream after the water flow repeatedly flows in sequence.

Here, the two water diversion plates located in the upstream-downstream relationship in the two rows of water diversion plates are different in distance from the bottom wall of the water tank, and the projection portions toward the bottom wall of the water tank are overlapped.

That is, the projected portion of one of the two rows of water diversion plates located in the upstream-downstream adjacent relationship toward the other water diversion plate falls on the other water diversion plate. Therefore, water flowing out of one water diversion plate can completely fall on the other water diversion plate and is drained again through the other water diversion plate, the condition that the water flow directly falls to the bottom of the water tank due to water flow loss is reduced, and water flow dropping noise is reduced.

In some examples, as shown in fig. 5, the distribution rules of the first row of water diversion plates in the four groups of water diversion plates are the same, and the distribution rules of the second row of water diversion plates in the four groups of water diversion plates are also the same. Specifically, the same distribution rule includes the same distribution interval, the same inclination angle, and the like.

the third inclination angle and the fourth inclination angle are acute angles, and the third inclination angle is larger than the fourth inclination angle; or, the third inclination angle and the fourth inclination angle are obtuse angles, and the third inclination angle is smaller than the fourth inclination angle.

Here, in connection with fig. 6, a set of water diversion plates is composed of a plurality of water diversion plates 121 connected to each other, and a set of water diversion plates corresponds to one water diversion hole 11 or a plurality of water diversion holes 11 for guiding water flow to the bottom wall B of the water tank.

That is, when the third inclination angle and the fourth inclination angle are both acute angles, the third inclination angle is larger than the fourth inclination angle; or when the third inclination angle and the fourth inclination angle are obtuse angles, the third inclination angle is smaller than the fourth inclination angle.

Here, the slope of the water deflector in the present disclosure that is upstream is steeper than the slope of the water deflector in the downstream for the water flow can flow from steep to slow to the bottom of the water tank along the water flow guide surface of the water deflector set, ensuring effective deceleration of the water flow, and reducing noise of the water flow.
