Description

  The present invention relates to a mist sauna apparatus, and more particularly to a bathroom mist sauna apparatus for performing a sauna bath using an existing bathroom without providing a dedicated sauna room.

  Mist saunas that perform sauna bathing by placing themselves in a hot mist atmosphere generated indoors have been known for a long time. In this case, an attempt has been made to use a bathroom with a bathtub and a washing place as a mist sauna room instead of a dedicated sauna room.

  When the bathroom is used as a mist sauna room, it is common to install a mist generator outside the bathroom (for example, Patent Document 1), but in that case, there is a problem that requires extensive construction. In addition, when the mist generator is installed in the bathroom, there is a problem that the generator becomes an obstacle during normal bathing.

  With regard to the above, although the purpose is heating in the bathroom, Patent Document 2 discloses an invention in which hot water is sucked from below a floating body floated on hot water in a bathtub and sprayed as mist from above. Therefore, it is easily conceivable for those skilled in the art to divert this to a sauna in the bathroom.

  On the other hand, a mist sauna with a particle size as small as possible (about 10 nanos) instead of a conventional mist sauna with a coarse particle size has no water wetting and the concentration of gaseous negative ions increases. It has been demonstrated that the feeling of bathing and health benefits are significantly improved (Non-patent Document 1). In this regard, it is a technical problem how to efficiently realize that a large amount of water is scattered with a limited device size and that the particle size of the scattered mist is made as small as possible. As an invention to solve this, in a processing chamber capable of introducing outside air, by immersing and rotating a cylindrical body with a screw in the lower part in water, pumping water upward from the lower part in the cylinder, The water and air provided above the cylinder collide with a cylindrical water sprinkling part through which air can pass and are allowed to pass through the water to make it mist. The present applicant has already proposed an invention in which a mist atmosphere containing negative ions is formed by being finely crushed by colliding with a cylindrical screen through which water and air arranged in the gas can collide with each other. (Patent Document 3).

  Then, if the thing of the said patent document 3 is employ | adopted as said mist generating apparatus of the said floating body, a more effective mist sauna will be implement | achieved.

  In this case, when the mist generating device is floated in hot water and the mist generating device is used as a mist sauna device, the mist sauna device floats in the bathtub and moves freely, so that an effect that does not disturb the bather can be obtained. Unlike the structure in which hot water is forcibly sucked up by the negative pressure from the pump as in the invention described in Patent Document 2, the structure in which hot water existing in the lower part of the cylinder is pumped with a screw. There was a risk that pumping would be interrupted due to the hot water inside. Furthermore, the cylinder immersed in the hot water becomes resistance when moving in the water, and the mist generator tilts carelessly, so that the hot water in the cylinder is interrupted and the pumping may be interrupted. In addition, the same phenomenon may occur due to a sudden rise and fall of the water level when the bather enters and exits the bathtub.

  The present invention was created for the purpose of providing a bathroom mist sauna apparatus that solves the above-mentioned problems, and rotates by immersing a hollow rotating body having a screw in the lower part thereof in hot water. This pumps up hot water from the bottom to the top of the rotating body, and scatters the hot water in the form of a mist from the cylindrical sprinkler that allows hot water and air to pass above the rotating body. A mist generating device for forming a mist atmosphere in a processing chamber and a floating body for floating the mist generating device in hot water stored in a bathtub with the lower end of the rotating body immersed in hot water. The lower part of the rotating body is formed in a dome shape with an opening for water intake at the lower end.

  In addition, here, as the second invention, mist that is scattered in a mist form from a cylindrical water sprinkler provided above the rotating body of the mist generator and through which air can pass is further disposed around the sprinkler. Also disclosed is a mist sauna device for a bathroom that is crushed more finely by allowing the hot water and air to pass through a cylindrical screen that can pass through.

In the present invention, hot water that is pumped upward from the bottom of the cylindrical body and splashes to the surroundings by the centrifugal force of the rotating cylindrical body collides with a water sprinkling portion that is composed of a cylindrical body through which hot water and air can pass. By passing through it, it is crushed into a mist and scattered. Examples of the structure of the watering part for this purpose are as follows.
(A) A cylinder with a large number of slits on the outer peripheral wall.
(B) A cylinder with a large number of pores on the outer peripheral wall.
(C) The outer peripheral wall of the cylinder is constituted by a mesh body.

Moreover, in the second invention, the mist is scattered by causing the mist scattered by the water sprinkling part to pass through the cylindrical screen that allows hot water and air arranged around the water sprinkling part to pass therethrough. Crush it more finely to form a mist atmosphere containing negative ions. Examples of the screen structure for this purpose are shown below.
(A) A cylinder with a large number of slits on the outer peripheral wall.
(B) A cylinder with a large number of pores on the outer peripheral wall.
(C) The outer peripheral wall of the cylinder is constituted by a mesh body.

  As described above, in the present invention, there are several possible structures for the water sprinkling unit that crushes hot water and scatters it into a mist, and the screen that crushes and scatters the mist from the sprinkling unit more finely. According to their experiments, it has been confirmed that the structure having a large number of slits in the outer peripheral wall of (A) for both the water sprinkling part and the screen has obtained good results in the negative ion generation effect. .

  Since the mist sauna device of the present invention is operated by floating in hot water stored in the bathtub by a floating body, the hot water in the bathtub is sucked up from the lower end of the rotating body immersed in hot water and used as a resource for generating mist. It is not necessary to provide a separate tank and a heating device is not required, so that a mist sauna device that is extremely compact and low in manufacturing cost can be realized.

  For the same reason as described above, when the mist sauna device of the present invention is not used as a sauna, it is not obstructed by ordinary bathing by removing it from the bathtub. Also, since it is floating in hot water, you can move freely in the bathtub, so even if the bather is immersed in the bathtub, you can enjoy the sauna bath in the bathtub by moving it to a place that does not get in the way It becomes possible.

  On the other hand, the mist sauna device of the present invention is configured in a dome shape in which a lower portion of the rotating body immersed in hot water is provided with an opening for water intake at the lower end, and as a result, the opening periphery of the rotating body is Because it lies almost horizontally (see Fig. 4), even if the rotating body suddenly moves laterally in the bathtub, the hot water flows into the rotating body from the tangential direction of the periphery of the opening, and the hot water is interrupted and pumped up. An effect of preventing interruption can be obtained.

  For the same reason as described above, the rotating body has less resistance in the hot water due to the dome surface, and even if it moves suddenly, the mist generator is prevented from inadvertently tilting, and hot water in the cylinder is interrupted and pumping is interrupted. Effects can be obtained.

  Further, in the second invention, by providing a cylindrical screen that rotates around the watering portion, the hot water is first crushed into a coarse mist by the watering portion and then crushed into a finer mist by the screen. Scatter. As a result, it is not necessary to attempt to make the mist particle size finer at the stage of the sprinkling part, so it is possible to set the size of the slits and pores so that hot water can pass through the outer peripheral wall of the sprinkling part well. It becomes possible, and a large amount of hot water can be used to generate mist.
