摘要 |
The present invention provides a novel water spray technique that extends a cleansing area in a two-dimensional manner without moving a nozzle.A nozzle head 170 has a water swirling chamber 171, which is located immediately below a nozzle opening 31 and connects with the nozzle opening 31 via a small-diametral connection pipe 163. The water swirling chamber 171 is formed as a hollow room having a tapered inner wall. A head flow path 34 is eccentrically connected to the water swirling chamber 171. Cleansing water flowed through the head flow path 34 into the water swirling chamber 171 swirls along the tapered inner wall of the water swirling chamber 171 as shown by the arrow SY and is sprayed from the nozzle opening 31 in a spiral (cone-shaped) form. |
