There is an advantage that a sore throat, hair drying and the like are not caused at the time of bathing, and a gentle bathing feeling can be obtained. Conventionally, a plurality of mist sauna devices have been proposed. JP-A-63-207927
The gazette proposes a bathroom heating device in which a steam generator that generates steam by boiling water is connected to a bathroom by piping, and steam is introduced into the bathroom. Japanese Utility Model Laid-Open Publication No. 1-138439 proposes a steam sauna apparatus in which warm water heated by a heater is atomized by an ultrasonic humidifier. JP-A-4-2418
No. 66 and Japanese Patent Application Laid-Open No. Hei 4-241867 propose a mist sauna apparatus in which hot water heated by a gas water heater is pressurized by a pump and sprayed through a nozzle.

[0003]

The above-mentioned conventional mist sauna apparatus requires a large amount of work when installed in an existing bathroom, has a complicated structure, is large, and is expensive. was there. The present invention has been made in view of the above-mentioned problems, and can be connected to a water tap provided in an existing bathroom without requiring large-scale construction, and has a simple structure, small size and low cost. It is an object of the present invention to provide a mist generator in which coarse particles are prevented from being mixed into the sprayed mist, and the amount of drop water that is discarded without being converted into a mist is small.

[0004]

In order to solve the above-mentioned problems, according to the present invention, there is provided a motor provided on one surface side of a disk-shaped base plate, and the other of the base plate and the base plate. A plurality of annular plates stacked in parallel with the base plate at a minute interval from each other on the surface side of the impeller, the impeller being rotationally driven by the motor, and an annular plate adjacent to the base plate. A set of a plurality of collision plates disposed in a ring shape at intervals in the radial direction outward of the gap and in the circumferential direction of the impeller; A mist generating device comprising: a set of a plurality of collision plates arranged in a ring shape at a distance from each other in a radially outward direction and in a circumferential direction of the impeller. In a preferred aspect of the present invention, the plurality of sets of collision plates are disposed so as to be shifted from each other in a circumferential direction. In a preferred aspect of the present invention, the collision plate is disposed in a swept wing shape with respect to the rotation direction of the impeller.

[0005]

In the mist generating device according to the present invention, when hot water or water is supplied to the central opening of the rotating impeller, the hot water or water is supplied to the gap between the base plate and the adjacent annular plate, or The fluid flows into the gap between the adjacent annular plates and is accelerated by tangential shearing force from the rotating base plate and the annular plate, forming a thin liquid film and moving radially outward. Flows to The liquid film of the hot water or water that has reached the outer edge of the gap, that is, the outer edge of the impeller, jumps out from the outer edge of the impeller in a substantially tangential direction while being crushed and atomized into fine mist. Hot water or water mist that has flowed out in a substantially tangential direction from the outer edge of the gap between the base plate and the adjacent annular plate is radially outward and circumferentially of the gap between the base plate and the adjacent annular plate. The impact plates, which are arranged in a ring shape at intervals in the direction, collide with the rear surface in the rotation direction of the impeller and are further miniaturized. The fine mist is sprayed into the bathroom. Warm water or water mist that has flowed out in a substantially tangential direction from the outer edge of the gap between the adjacent annular plates is radiated outward in the radial direction of the gap and around the impeller for each gap between the adjacent annular plates. Out of a set of a plurality of collision plates arranged in a ring at a distance from each other in the direction, the corresponding set of the plurality of collision plates collides with the rear surface in the rotation direction of the impeller, thereby further miniaturizing. Is done. The fine mist is sprayed into the bathroom.

In the mist generating device according to the present invention,
A thin liquid film is surely formed in the minute gap between the disc-shaped base plate and the annular plate provided in the rotating impeller or in the minute gap between the adjacent annular plates. The liquid film protrudes in a substantially tangential direction from the outer edge of the impeller and collides with the collision plate, whereby the liquid film is reliably crushed and atomized into fine mist. By stacking a plurality of annular plates on a disk-shaped base plate in parallel with a small interval therebetween, the amount of mist generation increases.

In the mist generator according to the present invention,
Since mist is generated by crushing a thin liquid film, not only hot water but also cold water can be atomized. That is, according to the mist generating device according to the present invention, not only mist of medium and high temperature but also mist of low temperature can be obtained. Also, when water is miniaturized by crushing, due to the Leonard effect,
Negative ions are generated efficiently. It is said that negative ions have a bactericidal effect, a sedative effect, and the like.

The mist generating device according to the present invention can be connected to a water tap provided in an existing bathroom without a large-scale construction by newly providing a pipe in the bathroom. Further, the mist generator according to the present invention has a simple structure, is small, and is inexpensive. By connecting the mist generating device according to the present invention to a water tap provided in an existing bathroom, a mist sauna device can be easily configured in the existing bathroom.

In the case where a set of a plurality of collision plates covering all the gaps formed by the base plate and the ring is disposed radially outward of the impeller, a certain one of the impellers is provided. While the mist that sticks out of the gap and adheres to the collision plate moves to the axial end of the collision plate, the mist jumps out of another gap of the impeller and coalesces with the mist that adheres to the collision plate to form coarse particles,
The coarse particles are sprayed into the bathroom from the axial end of the impingement plate. As a result, coarse particles are mixed in the sprayed mist. Some of the coarse particles formed on the collision plate are not sprayed into the bathroom and become waste water. As a result, the amount of discarded water that is discarded without becoming mist increases. In the mist generating device according to the present invention, hot water or water mist that has jumped out of the gap between the base plate and the adjacent annular plate, or the gap between the mutually adjacent annular plates, corresponds to each of the gaps. Since it collides with the collision plate dedicated to the gap, the mist adhering to the collision plate jumps out of other gaps of the impeller and merges with the mist attached to the collision plate while moving to the axial end of the collision plate. The possibility of forming coarse grains is low. Therefore, in the mist generating device according to the present invention, the mixing of coarse particles into the mist to be sprayed is suppressed, and the amount of discarded water that is discarded without being converted into a mist is small.

In the case where the plurality of sets of impact plates are arranged so as to be shifted from each other in the circumferential direction, the mist that has collided with each set of impact plates and made finer collides with the adjacent set of impact plates. It is sprayed into the bathroom without interfering with the fine mist. As a result, it is possible to prevent the mist from interfering with each other and uniting to form coarse particles.

When the impingement plate is disposed in a retreating wing shape with respect to the rotation direction of the impeller, the mist that has protruded substantially tangentially from the outer edge of the impeller impinges on the rear surface of the impingement plate in the rotation direction of the impeller. And collide at a substantially right angle when viewed in the direction of the rotation axis of the impeller. Thereby, miniaturization of the mist is promoted.
