いる。 To explain this, the drainage channel 4' rises from the bottom surface of the ball part 2' along the back side wall of the ball part 2', makes a U-turn from a position where a constant water level can be maintained in the ball part 2', and breaks halfway. While bending, it communicates with the drain port 11' at the bottom of the toilet body A', and part of the flushing water flows from the tip of the rim passageway 6', through the headrace channel 9', and from the fountain hole 10' in the form of a jet, and flows into the drain channel 4. Water is sprayed toward the inlet 4a' of the tank.
従つて、噴水孔10′より射水された洗浄水は
排水路4′をUターン部分13′に向けてかけ昇り
