  2A and 2B are overall three-dimensional schematic views of the first embodiment of the present invention viewed from different angles. As shown in the figure, the crushing device 60 of the present invention is attached to the mist sauna device 10. The mist sauna device 10 includes a circulating air blower 11 that circulates indoor air, a heating device 12 that heats the air, and a humidifying device 20 that is provided downstream of the heating device 12 and humidifies the air, The circulation blower 11 is a centrifugal blower, and the heating device 12 is a PCT heater. The humidifier 20 is provided with a water storage part 21 for storing water at the lower part and a humidifying part 22 for sucking up and spraying water stored in the water storage part at the upper part. A substantially conical crushing device 60 having a plurality of ribs 61 is provided around the humidifying unit 22, and an air flow passage opening 62 is formed between the plurality of ribs 61. 21 is fixed.

  FIG. 3 is a three-dimensional schematic diagram of the crushing device 60 of the first embodiment according to the present invention. As shown in the figure, the crushing device 60 has a substantially conical shape that extends outward toward the top, has an opening 62 that forms a circulation port for the swirling air, and is generated by a collision with the rib 61. It has a plurality of draining portions 611 that capture large water droplets contained in the air. Each drainer 611 has a “<” shape when viewed from the bottom of the conical shape. Each draining portion 611 has a shape that narrows toward the bottom.

  The “<”-shaped draining portion 611 provided in the crushing device 60 is installed at a predetermined angle toward the center 64 with respect to the draining portion 611 on the center side. The outer side of the “<”-shaped draining portion of the crushing device 60 is formed by an inclined surface 66 having an angle that spreads outward with respect to the circumference 65 of the crushing device 60, that is, an acute angle with respect to the tangent.

  Further, as shown in FIGS. 2A and 2B, the humidifying unit 22 is a substantially conical rotating body having an opening 63 having an inclination extending toward the upper part, and water is supplied from the water storage unit 21 provided at the lower part. On the other hand, the air flow blown by the circulating air blower 11 enters and rises into the crushing device 60 from the opening 62 of the crushing device 60 provided around the humidifying unit 22, and on the other hand, Of the water droplets sprayed from the humidifying unit 22, large particles are collected by the draining unit 611 of the crushing device 60 that shrinks downward when gravity falls to the lower part, and flow into the water storage unit 21 again. Each draining part 611 of the “<” shape of the crushing device 60 was made to become thinner as it goes downward. The specific process is as follows.

  The outer side of the “<”-shaped draining portion of the crushing device 60 is formed as a slope having a forming angle that spreads outward with respect to the circumference of the crushing device 60. The air flow blown by the circulating air blower 11 is taken in while being swirled into the crushing device 60 along the slope of the draining portion 611 of the “<” shape that protrudes to the outside of the crushing device 60, and is humidified. The fine water droplets ejected from the part 22 come into contact with the inside of the crushing device 60.

  When the air flow enters the crushing device 60, it is guided along the surface of the “<”-shaped draining portion 611, so that there is no turbulence and the air resistance of the air flow entering the crushing device 60 is reduced. . Therefore, pressure loss of air can be reduced, and vibration and noise can be reduced.

  The air flow is smoothly guided to the inside of the humidifying unit 22, and the wind direction is changed to the center of the humidifying unit 22 by a “-” shaped plate to become a swirling flow. On the other hand, the water sprayed from the humidifying unit 22 collides with the edge of the draining unit 611 at right angles to form fine water droplets, and comes into contact with the swirling flow inside the crushing device 60 having the highest density for a long time. Since the air flow makes contact while swirling inside the crushing device 60 having a high density, the humidifying ability is high.

  In the above process, the water droplets ejected from the humidifying unit 22 collide with the ribs 61 to form fine water droplets, and each of the “<”-shaped draining portions 611 of the crushing device 60 is thinned toward the lower part. Therefore, the large water droplets fall along the draining part 611 of the crushing device 60. Therefore, the path of the fine water droplet and the large water droplet is divided, and the fine water droplet is not absorbed by the large water droplet. Therefore, the highly efficient mist sauna apparatus 10 can be provided. The water recovered by the draining unit 611 of the crushing device 60 falls along the slope of the draining unit 611, but becomes thinner toward the lower part, and the water droplets that have flowed down separately coalesce and become larger. The water is collected in the water storage unit 21 without being scattered again by the swirling flow in the unit 22. The recovered large water droplets are not re-scattered, and the large water droplets also have an action of absorbing and combining surrounding fine water droplets. As described above, the water droplets are not blown out from the product, and the re-scattering of the large water droplets into the air flow is suppressed, so that the humidifying ability of the mist sauna device 10 can be increased.

  Further, as shown in FIGS. 2B and 3, a second drainer having an angle that extends in the same direction as the “<”-shaped drainer 611 of the crushing device 60 on a part or all of the ribs 61. A portion 612 is provided. The center of the cylinder which the indoor air suck | inhaled by the circulation air blower 11 is heated by the heating apparatus 12, penetrate | invades from the opening 62 between the ribs 61 of the crushing apparatus 60 provided around the humidification part 22, and generates a fine water droplet. The first air outlet of the humidifying device 20 provided in part of the circumference of the crushing device 60 is brought into contact with the water droplets sprayed from the humidifying unit 22 rotating about the axis, turns up as humidified air and turns. It will be guided to the air path communicating with 100. After the second draining portion 612 is provided on the upper part of the ribs 61, the humidified air is guided to the first outlet 100 of the humidifying device 20 while colliding with the second draining portion 612. In this way, the humidified air containing fine water droplets is further separated into large water droplets and fine water droplets by colliding with the second draining portion 612 and the cyclonic effect due to the swirling flow, and only the fine water droplets are separated from the second of the humidifying device 20. Therefore, water droplets do not fall from the air outlet (not shown) of the mist sauna device 10.

  FIG. 4 is an overall three-dimensional schematic diagram of the second embodiment according to the present invention. 5A and 5B are schematic views in which the cover of the crushing device of the second embodiment according to the present invention is removed. As shown in the figure, a ring-shaped cover 104 was provided from the upper open end of the crushing device 60 toward the center side. Water droplets sprayed from the humidifying unit 22 merge with the swirl flow introduced from between the plurality of ribs 61 of the crushing device 60. The large water droplets rise along the outer periphery of the inner surface of the crushing device 60 due to the centrifugal force of the swirling flow, collide with the ring-shaped cover 104, flow downward along the draining portion 611, and are stored. Further, the fine water droplets collected at the center of the swirling flow due to the centrifugal force are ejected out of the humidifying unit 22 through the hole 105 provided at the center of the cover 104. Therefore, the large water droplets and the fine water droplets are completely separated and rise along the outer periphery by centrifugal force, so that the large water droplets adhere to the air passage after passing through the crushing device 60 and the large water droplets are condensed. Then, it is possible to suppress peeling and scattering and dropping from the first air outlet 100.

  The air blown out from the circulating blower 11 that circulates the indoor air changes its direction from the direction of the heating device 12 (that is, the direction perpendicular to the first blower outlet 100) to the first blower outlet 100. Since the air flows, the wind concentrates on the ribs 61A and 61B close to the first air outlet 100 of the humidifier 20, and the wind speed at the opening between the ribs 61A and 61B increases. That is, as shown in FIG. 5A, in this embodiment, the wind speed between the openings 62 between the three ribs 61 </ b> A (occupying about one sixth of the total number) located on the outer surface of the first outlet 100. Is the fastest, and the wind speed between the openings 62 between the eight ribs 61C (occupying about one-half of the total number) located on the back surface of the first air outlet 100 away from the first air outlet 100 is Between the openings 62 between the seven ribs 61B (occupying about one third of the total number) facing the first air outlet 100 which is the slowest and the closest to the remaining first air outlet 100. Wind speed is medium.

  The one half, one third, one sixth, and the like in the present embodiment are not limited to be fixed, and can be adjusted by the actual operating condition of the humidifying unit 22 and the size of the first outlet 100. . In other words, you can install more or less, for example, two-thirds, one-eighth, etc.

  In the present embodiment, the opening 62 between the ribs 61 </ b> A having a high wind speed passing through the periphery of the crushing device 60 and close to the first air outlet 100 is completely blocked, and the first air outlet of the humidifying device 20 is used. A part of the opening 62 between the nearest ribs 61B is blocked, but the opening 62 between the other ribs 61C is not blocked. By the cover plate 70 provided in the opening 62 between 61A, a water droplet is not conveyed but the opening 62 is closed so that it may hit and hit the cover plate 70 between the ribs 61A.

  The rib 61B close to the first air outlet 100 of the humidifier 60 is the other rib 61B excluding the rib 61A on the left half side close to the first air outlet 100 of the crusher 60 as shown in FIG. 5A. That's it. In order to prevent the air volume from becoming too small by closing the opening 62 of the crushing device 60, the upper half of the rib 61B may be closed and the lower half opened. Thus, air can flow to the first air outlet 100 through the opening 62 in the lower half part between the ribs 61B.

  Moreover, it is difficult for large water droplets to be transported from the lower half opening 62 between the ribs 61 </ b> B to the first outlet 100 higher than the upper part due to gravity, and only fine water droplets are transported. . Further, since the wind speed is slow on the rib 61C side, the water droplets ejected from the humidifying unit 22 are moved by the wind, but since there is a distance to the first air outlet 100, the water droplets fall during the movement or adhere to the wall. By doing so, when arriving at the first outlet 100, only fine water droplets remain.

  Moreover, when a wind flows into the 1st blower outlet 100 along a circular arc from the heating apparatus 12, the wind speed inside the crushing apparatus 60 becomes low compared with the outer side. For this reason, the wind which passed through the rib 61B and its periphery becomes a slow speed.

  In this way, by closing the openings 62 between the ribs 61 </ b> A having a high wind speed that passes around the crushing device 60 and between the ribs 61 </ b> B close to the first air outlet of the humidifying device 20, It can suppress that the large-sized water droplet ejected is conveyed by an air flow, and can suppress that a large-sized water droplet drip from the 1st blower outlet 100.
