As shown, a crushing device 60 of the present invention is mounted on a micro-mist sauna device 10. The micro-mist sauna apparatus 10 includes a circulating air blowing device 11 that circulates indoor air, a heating device 12 that heats air, and a humidifying device 20 that is provided with humidified air on the downstream side of the heating device 12, and the circulating air blowing device 11 is centrifugal. The blower, the heating device 12 described above is a PCT heater. The humidifier 20 is provided with a water storage unit 21 for storing water in the lower portion, and a humidifying unit 22 for sucking up the water stored in the water storage unit 21 and spraying the upper portion, and the humidifying unit 22 is provided with a plurality of humidifying portions 22 The slightly conical crushing device 60 of the rib 61 has an opening 62 for an air flow passage formed between the plurality of ribs 61, and the crushing device 60 is fixed to the water storage portion 21.

Fig. 3 is a perspective view showing the crushing device 60 of the first embodiment of the present invention. As shown in the figure, the crushing device 60 has a shape that is upwardly and outwardly enlarged, and is formed in a slightly conical shape, and has an opening 62 that forms a flow port of the spiraled air, and has a catching passage to collide with the rib 61. A plurality of dripping portions 611 of the large water droplets contained in the air are generated. Each of the drip portions 611 has a "<" shape when viewed from the perspective of the bottom surface of the conical shape. Each of the drip portions 611 has a shape that becomes thinner as it goes to the lower portion.

The center side of the "<"-shaped dripping portion 611 provided in the crushing device 60 is provided at a constant angle to the center 64 with respect to the outer drip portion 611. The outer side of the dripping portion of the "<" shape of the crushing device 60 is formed with a slope 66 which forms an angle which is enlarged toward the outside with respect to the circumference 65 of the crushing device 60, that is, an oblique angle 66 which forms an acute angle with the tangent.

Further, as shown in FIG. 2A and FIG. 2B, the humidifying portion 22 is a substantially conical rotor having an inclined opening 63 that is enlarged upward, and is sucked and sprayed from the water storage portion 21 provided at the lower portion, and is circulated on the one hand. The air flow blown by the air blowing device 11 enters the inside of the crushing device 60 from the opening 62 of the crushing device 60 provided around the humidifying portion 22, and rises, and on the other hand, the large particle water droplets in the water droplets sprayed from the humidifying portion 22 When it falls to the lower part by gravity, it collects by the dripping part 611 of the crushing device 60 which shrinks to the lower part, and re-flows into the water-storing part 21. Each of the dripping portions 611 of the "<" shape of the crushing device 60 has a shape that becomes thinner as it goes to the lower portion.

The specific process is as follows:

The outer side of the drip portion of the "<" shape of the crushing device 60 is formed with an inclined surface which is formed to be expanded outward with respect to the circumference of the crushing device 60. By circulating air The air flow blown out by the apparatus 11 enters the inside of the crushing device 60 while being spirally slanted along the inclined surface of the drip portion 611 of the outer shape of the "<" shape protruding toward the outside of the crushing device 60, and is ejected from the humidifying portion 22. The fine water droplets are in contact with each other inside the crushing device 60.

When the air flow enters the inside of the crushing device 60, since the surface of the drip portion 611 along the "<" shape is guided, turbulence does not occur, and the air resistance of the air flow entering the crushing device 60 becomes small. This makes it possible to reduce vibration and noise while reducing the pressure loss of the air.

The air flow is smoothly guided to the inside of the humidifying portion 22, and the wind direction is changed toward the center of the humidifying portion 22 by the "<"-shaped plate to form a spiral flow, and on the other hand, the water and drip portion 611 sprayed from the humidifying portion 22 The edges collide at right angles to produce fine water droplets, which are in contact with the above-described spiral flow in the interior of the highest density crushing device 60 for a long time. Since the air flow is spirally contacted while being inside the high-density crushing device 60, it is possible to have a high humidifying ability.

In the above process, the water droplets ejected from the humidifying unit 22 collide with the ribs 61 to form fine water droplets, and the respective dripping portions 611 of the "<" shape of the crushing device 60 become thinner toward the lower portion. The shape, therefore, the large particle water droplets fall along the drip portion 611 of the crushing device 60, and the fine water droplets are distinguished from the path of the large particle water droplets, so that the fine water droplets are not absorbed by the large particle water droplets, thereby providing efficient micro Fog sauna device 10. The water recovered by the dripping portion 611 of the crushing device 60 is dropped downward along the inclined surface of the drip portion 611. However, since the lower portion becomes thinner and the water droplets flowing down are integrated into one body, they are not enlarged. The spiral flow in the humidifying portion 22 is again splashed, but is recovered in the water storage portion 21, and the large water droplets to be recovered are not splashed again, and the large water droplets also have the function of absorbing and absorbing the surrounding fine water droplets. Thereby, water droplets are not blown out from the product, and the humidification ability of the micro-mist sauna apparatus 10 can be increased by suppressing the splash of large water droplets into the air flow again.

Further, as shown in FIG. 2B and FIG. 3, a second drip portion 612 extending in the same direction as the "<"-shaped dripping portion 611 of the crushing device 60 is provided on the upper portion of some or all of the ribs 61. The indoor air sucked by the circulating air blower 11 is heated by the heating device 12, and enters from the opening 62 between the ribs 61 of the crushing device 60 provided around the humidifying portion 22, and the center of the cylinder is generated by the fine water droplets. The water droplets ejected from the humidifying portion 22 that the shaft rotates are in contact with each other, and the humidified air is swirled upward, and is guided to an air passage that is provided in a part of the circumference of the crushing device 60 and that communicates with the first air outlet 100 of the humidifying device 20. a second portion of the upper portion of the rib 61 After the drip portion 612, the humidified air is guided to the first air outlet 100 of the humidifying device 20 while colliding with the second drip portion 612. Thus, the humidified air containing the fine water droplets collides with the second drip portion 612 and the cyclone effect due to the swirling flow, so that the large particle water droplets and the fine water droplets are separated into one, and only the fine water droplets are discharged to the humidifying device 20 for the second time. The tuyere 200 is blown out, so that the air outlet (not shown) of the micro-mist sauna device 10 does not drip water droplets.

Figure 4 is a perspective view of a second embodiment of the present invention. Figure 5A and Figure 5B are schematic views of the crushing device of the second embodiment of the present invention with the cover removed. As shown in the figure, the crushing device 60 is provided with an annular cover 104 from the upper open end toward the center side. The water droplets sprayed from the humidifying portion 22 pass through the spiral flow introduced between the plurality of ribs 61 of the crushing device 60, and the large particle water droplets rise along the outer circumference of the inner surface of the crushing device 60 with the centrifugal force of the spiral flow, and collide with the ring shape. The cover 104 is further stored downstream of the drip portion 611 and stored therein, and fine water droplets concentrated in the center of the spiral flow due to the centrifugal force are ejected from the hole 105 provided at the center of the cover 104 to the outside of the humidifying portion 22, and large particles of water droplets and The fine water droplets are completely separated and rise along the outer circumference due to the centrifugal force, and it is possible to suppress the adhesion of large particle water droplets in the air passage after passing through the crushing device 60, or the large particle water droplets to be condensed and then peeled off and scattered, and dripped from the first air outlet 100.

Since the air blown from the circulating air blowing device 11 that circulates the indoor air is turned into the first air outlet 100 from the direction of the heating device 12 (that is, a direction at right angles to the first air outlet 100), the wind is concentrated close to the air. At the ribs 61A, 61B of the first air outlet 100 of the humidifying device 20, the wind speed of the opening between the ribs 61A, 61B is increased. That is, as shown in FIG. 5A, in the present embodiment, the wind speed between the openings 62 between the three ribs 61A (one sixth of the total number) on the outer side of the first air outlet 100 is the fastest; away from the first air outlet 100. The wind speed between the openings 62 between the eight ribs 61C (about one-half of the total number) located at the back of the first air outlet 100 is the slowest; and the remaining closest to the first air outlet 100, facing the front The wind speed between the openings 62 between the seven ribs 61B of the first air outlet 100 (about one-third of the total number) is centered. The one-half, one-third, one-sixth, etc. described in the present invention is not a fixed definition, and may be adjusted according to the actual working condition of the humidifying portion 22 and the size of the first air outlet 100. , that is, it can be more or less, such as two-thirds, one-eighth, etc.

The utility model completely blocks the opening 62 between the ribs 61A passing through the crushing device 60 and having a relatively high wind speed near the first air outlet 100, and partially blocking the closest to the humidifying device The opening 62 between the ribs 61B of the first air outlet of 20, but the opening 62 between the other ribs 61C is not blocked.

The wind speed around the crushing device 60 is relatively fast and is close to the rib 61 A of the first air outlet 100. The sealing plate 70 is disposed through the sealing plate 70 disposed between the ribs 61A, so that the water droplets are not transported. The sealing plate 70 that is struck between the ribs 61A is bounced back.

The rib 61B of the first air outlet near the humidifying device, that is, as shown in FIG. 5A, the crushing device 60 is close to the other rib 61B of the left half of the first air outlet 100, and the rib 61B is removed. It is prevented that the air volume is too small because the opening 62 of the crushing device 60 is blocked, and the rib 61B can be configured such that the upper half is closed and the lower half is open so that air can flow through the opening 62 between the lower half of the rib 61B. An air outlet 100.

Further, due to gravity, large particle water droplets are difficult to be carried by the air flow from the opening 62 in the lower half between the ribs 61B to the upper first air outlet 100, and only the fine water droplets are carried. And because the wind speed is slowed down at the rib 61C, the water droplets ejected from the humidifying portion 22 are moved by the wind, but since there is a distance to the first air outlet 100, the water droplets may fall or attach to the wall during the movement. Therefore, only the fine water droplets remain when reaching the first air outlet 100.

When the wind flows from the heating device 12 to the first air outlet 100 along the circular arc, the wind speed on the inner side of the crushing device 60 is lower than the wind speed on the outer side. Therefore, the wind speed through the rib 61B and its surroundings is low.

As described above, by clogging the opening 62 between the ribs 61A passing the faster wind speed around the crushing device 60 and the ribs 61B near the first air outlet of the humidifying device, it is possible to suppress the ejection to the crushing. The large particle water droplets on the outside of the device 60 are carried by the air flow, thereby suppressing the dripping of the large particle water droplets from the first air outlet 100.
