The drive motor is fixed on the sealing base and is used to drive the water distribution mechanism to rotate. The advantage of this structure is that the water outlets are reasonably distributed. The five water outlets can be provided for the dishwasher to connect to five spray arms respectively. The dishwasher manufacturer can set the spray mode of the dishwasher according to these five water outlets, thereby increasing the spray mode selection of the dishwasher and making the dishwasher more practical.

[0016] The sealing base 10 is provided with a transmission shaft 11. The bottom of the transmission shaft is connected to the rotation of the drive motor, and the top of the transmission shaft extends into the water distribution chamber and is connected to the water distribution mechanism. The sealing base has a hole for the transmission shaft to pass through. In order to improve the sealing performance, a sealing ring is set between the transmission shaft and the hole to improve the sealing performance and prevent water leakage.
