<p>A water pump supplies washing water to a human body washing nozzle at a pressure that fluctuates, and an air pump supplies air to the human body washing nozzle. When a pressure of the air supplied from the air pump exceeds a pressure of the washing water supplied from the water pump, the air is mixed in the washing water. The washing water is parted by the air in a linear flow path of the human body washing nozzle, and the parted washing water is intermittently sprayed from a hole as separate water masses.</p> |
