The invention relates to a pedestal pan which comprises a
defecation basin and a seat ring. A
throat ring waterway is arranged in the seat ring, the defection basin is provided with a main waterway communicated with a
water source and a spraying waterway connected with the main waterway, the spraying waterway extends along a
sewage receiving face of the defection basin, a first through hole communicated with the main waterway is formed in the
defecation basin, a second through hole communicated with the
throat ring waterway is formed in the seat ring, the first through hole and the second through hole are mutually communicated and combined to form a water-air passage connected with the
throat ring waterway, and an inclined section is arranged at a position where the main waterway is connected with the spraying waterway and used for guiding part of flushing water flowing into the spraying waterway from the main waterway into the water-air passage. Compared with the prior art, the pedestal pan has the advantages that the whole pedestal pan is small in size, simple in production process and high in product qualified rate, the problems of both
water supply of the throat ring waterway and air exhaust of the main waterway and the spraying waterway are solved, and the pedestal pan can have powerful flushing effect while little water is consumed.
