Description

  The present invention relates to a western style flush toilet that discharges wash water along an inner wall surface of an upper edge of a ball surface to wash the ball portion.

  Conventionally, Patent Document 1 discloses a technique for forming a water discharge port for discharging cleaning water along the inner wall surface of the upper edge of the ball surface.

In Patent Document 1, a rim portion molded body and a trunk portion molded body are formed by separately forming a communication path and a through passage for supplying cleaning water from a cleaning water supply device such as a water discharge port and a water storage tank to the water discharge port. It is formed by joining. In other words, the space formed by the concave shape provided in the rim part molded body and the concave shape provided in the body molded body is a communication path and a through path, and the opening end on the bowl side of the space part is the water outlet. It is said.
Therefore, it is necessary to configure the water conduit while combining the concave shape of the rim part molded body and the concave shape of the body molded body up to the position where the water outlet is disposed, and it is structurally possible to configure the water outlet at an arbitrary position. It can be difficult.
