The user turns on the operation switch while wearing clothes, leaves the bathroom, and undresses. The mist spray is started while the user is undressing outside the bathroom. When the undressed user enters the bathroom, the temperature and humidity inside the bathroom have already reached appropriate values, and the user can immediately take a mist and obtain a comfortable bathing feeling. Even if the user turns on the operation switch while wearing clothes, there is no danger that the clothes will get wet and a comfortable environment is already formed when the user enters the bathroom after undressing. Therefore, the mist generating device is convenient for the user.

In the mist generator according to the present invention,
When the operation switch is turned on, the operation of the controller causes
After a lapse of a predetermined time after the operation switch is turned on, the opening / closing valve is opened, hot water is supplied to the atomizing device, and the atomizing device is started. The mist of warm water atomized by the atomizer is sprayed into the bathroom.

Further, the mist generator according to the present invention has a simple structure, is small in size, and is inexpensive. By connecting the mist generating device according to the present invention to the existing hot water supply / water supply pipe in the bathroom, the mist sauna device can be easily configured in the bathroom.

In the mist generator according to the present invention,
When the operation switch is turned on, the operation of the controller causes
After a lapse of a predetermined time after the operation switch is turned on, the open / close valve is opened, hot water is supplied to the central portion of the base plate, and the motor is started. The hot water supplied to the central portion of the base plate is subjected to a shearing force in a tangential direction from the rotating base plate to be accelerated and forms a thin liquid film, while flowing on the base plate radially outward. The outer edge of the base plate, that is, the hot water or the liquid film of water reaching the outer edge of the impeller, from the outer edge of the impeller,
While crushing and atomizing into fine mist, it jumps out in a substantially tangential direction. Warm water or water mist that jumps out in a substantially tangential direction
The impingement plates, which are arranged radially outward of the impeller and are spaced apart from each other in the circumferential direction, collide with the rear surface of the impeller in the rotational direction of the impeller and are further miniaturized. The mist that has been made fine by the collision with the collision plate is reflected and sprayed from the mist generator into the bathroom.

In the mist generator according to the present invention,
When hot water is supplied to the central opening of the impeller, the hot water flows into a flow path of a minute height formed between the base plate and the annular plate or between the adjacent annular plates, and the rotating base plate, the circle. Shearing force is applied in a tangential direction from the ring plate and accelerated, and a thin liquid film is formed while flowing radially outward in the flow path. The outer edge of the flow path, that is, the liquid film of warm water that has reached the outer edge of the impeller,
While crushing and atomizing into fine mist from the outer edge of the impeller,
It jumps out almost tangentially. The mist of warm water that has sprung out in a substantially tangential direction collides with the rear surface of the impeller, which is arranged radially outward of the impeller and is spaced apart from each other in the circumferential direction, in the direction of rotation of the impeller, and is further miniaturized. To be done. The mist that has been made fine by the collision with the collision plate is reflected and sprayed from the mist generator into the bathroom.

In the mist generator according to the present invention,
A thin liquid film is reliably formed in a flow path of a minute height formed between a disk-shaped base plate and a circular ring plate provided in a rotating impeller or between adjacent circular plates, and the thin liquid film is formed. The liquid film of spills out in a substantially tangential direction from the outer edge of the impeller and collides with the collision plate, so that the liquid film is reliably crushed and atomized into fine mist. The amount of mist generated is increased by stacking a plurality of annular plates in parallel on a disk-shaped base plate with a small gap therebetween.

When the mist generating device is provided with a display means for displaying the operating state of the mist generating device, the user can use the mist generating device while clearly recognizing the operating state of the mist generating device. The usability of the generator is further improved.
