  When bath mist is bathed using such a mist spraying device, the direction of the bath mist spraying is adjusted so that the bath mist strikes almost the entire body. In the conventional mist spraying device, the pole is rotated. By adjusting, the ejection direction of the bath mist is adjusted so that the bath mist hits substantially the entire body.

By the way, some people have a request to make the contact state of the bath mist with a part of the body different from the contact state of the bath mist with another part of the body. For example, there are people who feel uncomfortable when bathing mist hits the entire face, and such people want to avoid bathing mist as much as possible while applying bathing mist enough to other parts of the face I have a request.
However, in the conventional mist ejection device, if the rotation of the pole is adjusted, the orientation of the plurality of nozzles is integrally changed and adjusted, so that the above-mentioned human demand cannot be satisfied and the usability is poor. there were.

In some cases, the interior of the bathroom is preheated by the ejection of a bath mist before bathing. When preheating the interior of the bathroom, it is preferable to warm the floor of the washing area over the entire surface.
That is, since the bather usually takes bath mist at the washing place, the bath mist can be comfortably bathed by heating the floor surface of the washing place over substantially the entire surface.
However, in the conventional mist spraying device, since the spraying range of the bath mist in the direction along the circumferential direction of the pole is narrow, when preheating the bathroom, it is difficult to warm the floor surface of the bathroom washing area over the entire surface. Was bad.
Incidentally, since there is a limit in increasing the spray range of the bath mist of each nozzle, the conventional mist spray device narrows the spray range of the bath mist in the direction along the circumferential direction of the pole.

  This invention is made | formed in view of this situation, The objective is to provide the mist ejection apparatus which can improve usability, while being excellent in installation property and operativity.

The mist ejection device of the present invention ejects a bath mist into a room,
In the first characteristic configuration, a plurality of mist ejection nozzles are provided in each of a plurality of cylindrical movable frames that are arranged along the longitudinal direction of the same axis and that can be individually rotated and adjusted around the axis. ,
