Further, although the straight water discharge pipe 40 is said to have a first straight water discharge pipe 41, a second straight water discharge pipe 42, and a third straight water discharge pipe 43, the straight water discharge pipe 40 may not have a third straight water discharge pipe 43. .. For example, a flow path leading to the straight water discharge port 14 may be formed inside the air supply pipe 50 in the water discharge unit 20 instead of the third straight water discharge pipe 43.

Further, the membrane-like water discharged from the membrane spout 12 is said to be formed in an annular shape (for example, an annular shape) in a plan view, but the present invention is not limited to this. For example, the film-like water may be formed in a linear shape (for example, a curved line or a straight line) instead of an annular shape in a plan view.

Although the present invention has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various modifications and modifications are obvious to those skilled in the art. It should be understood that such modifications and modifications are included within the scope of the invention as long as it does not deviate from the scope of the invention according to the appended claims.
