There is a simple flushing type described in Japanese Patent Publication No. 270, both of which form a water discharge nozzle at the rear of the ball surface and an air inlet at the lower part of the stool drop below the ball surface. The odor is removed by suction from a lower intake port on the ball surface and exhausted.

[0003] As described above, in the case where the water discharge nozzle and the suction port are disposed vertically, the number of parts is increased because both are installed individually, the labor for assembly work is increased, and the production cost is increased. Is getting higher. And since the air intake port is located downstream of the toilet drop below the ball surface, when the defecation pipe below the toilet drop is clogged or the toilet pan cannot be opened, it sucks in dirt and waste water. As a result, the intake pipe may be clogged, or the exhaust fan may be damaged. Another problem is that the odor is lighter than air, and it is difficult to forcibly pull down the odor that tends to rise in the ball surface due to the difference in specific gravity, and it is difficult to remove the odor. Although it is possible if the fan has a high output, a considerable suction force is required, and even with such a suction force, even dirty water is sucked, and the wind at the time of suction is strong and unpleasant. .
