In the mist sauna device of Patent Document 1, a compressor or the like is used as the air pressure adjusting means, which makes the device large and complicated. Since the number of revolutions is changed by the control unit, there is a problem that the size of the apparatus is increased and the cost is increased.

The applicant of the present application previously applied for a mist generator or the like according to Patent Document 3, which has a water ejector in which a rotating chamber is formed between an inner cylinder member for introducing water and an outer cylinder member. A rotating stream of water is generated in a room, ejected from an ejection port, and pulverized by a cylindrical pulverizing member to generate mist. A flange member is arranged above the pulverizing member, and when the generated mist rises, water droplets of the mist attached to the flange member and turned into water droplets are dripped inside the pulverizing member and stored. The mist adheres to the peripheral portion of the pulverizing member, which prevents water droplets from dripping.

Here, there is a problem of whether or not the size of the particle size of the mist generated from this mist generator can be adjusted. For example, when managing plants in a greenhouse, a mist with a relatively large particle size is desirable in the summer because the cooling effect is given priority, and a mist with a relatively small particle size is effective in the winter because the humidification effect is given priority. is. Therefore, there has been a demand for a mist generator that can easily change the particle size of the mist according to the season or the like.

In general, mist sprayers for agriculture are mainly used for cooling and for humidification. Cooling sprays are mainly used as countermeasures against high temperatures in summer, so a spray amount of about 3 to 5 times the required amount is required to maximize the cooling effect. On the other hand, since it is used under high temperature conditions of 30 degrees or more, some wetting is often allowed. Humidifiers are mainly used to prevent dryness from winter to spring, and since they are used at temperatures of 10-25°C, wetness is unacceptable.

However, in the conventional high-pressure method, in order to cover both conditions, it is necessary to spray fine-grained mist for humidification in the amount required for cooling applications. The period of use was only 3 to 4 months during the high temperature period, and the facility utilization rate was poor, resulting in high operating costs.

In addition, in the case of large greenhouses, it was difficult to keep the temperature and humidity inside the greenhouse uniform because the solar radiation, ventilation, and ventilation conditions differ greatly depending on the location. Unevenness in temperature and humidity in greenhouses affects plant growth and the risk of disease outbreaks, and is a factor that destabilizes the yield and quality of crops. In agricultural production, in order to reduce the effects of such uneven temperature and humidity, it is necessary to manually perform tasks such as partial irrigation, shading, and selection of leaves and fruits, which is a factor in reducing productivity.

The mist generating device 2 includes a water ejector 6 having a rotating chamber formed therein, a cylindrical pulverizing member 8 which collides with the water ejected from the water ejector 6 to generate mist 7, and an annular flange member 12. have. Here, the crushing member 8 is arranged below the flange member 12, and both are joined and integrated. Also, the water ejector 6 and the crushing member 8 are housed in a housing container 9 .

Furthermore, in this embodiment, an annular particle size adjusting member 10 is arranged above the flange member 12 to adjust the size of the particle size of the mist 7 emitted from the crushing member 8 . In this case, as the particle size adjusting member 10, a plurality (here, four types) of different inner diameters are exchanged according to the need for air conditioning (humidification, cooling, etc.), and the particle size of the emitted mist 7 is adjust the

The flange member 12 is a base member on which the particle diameter adjusting member 10 can be easily attached and detached. In addition, the flange member 12 also has a function to prevent the dripping of the mist 7, which may adhere to the storage container 9, etc., grow, and form water droplets, and to prevent the lower part from getting wet. .

The water ejector 6 is used by being connected to a water supply pipe 4 as a water supply path, as shown in FIG. The water ejector 6 has an inner cylinder member 16 for introducing water supplied from the inlet 14 of the water supply pipe 4, and an outer cylinder member 18 provided outside the inner cylinder member 16. A doughnut-shaped (annular cross section) rotation chamber 20 is formed in the space between the outer cylinder member 18 and the outer cylinder member 18 .

A water inlet 14 is provided in the upper portion of a cylindrical inner cylinder member 16, and the lower portion thereof is closed with a bottom member. The inner cylinder member 16 is provided with an injection hole 22 for injecting water into the rotation chamber 20 , and the outer cylinder member 18 is provided with an ejection hole 24 for ejecting the water in the rotation chamber 20 .
The injection holes 22 are provided at predetermined intervals around and above and below the cylindrical portion of the inner cylindrical member 16 , and water introduced into the inside from the inlet 14 is injected into the rotation chamber 20 through the injection holes 22 . be.

The injection hole 22 injects water into the rotation chamber 20 in a direction inclined from the normal direction to the direction in which the water is rotated, thereby generating a rotating water flow 28 in the rotation chamber. Therefore, the injection hole 22 is formed so that the injection angle of water is inclined from the radial direction to the tangential direction (rotational direction).
The injection angle (.theta.) of the injection hole 22 is suitably around 30 degrees, for example, and the hole shape of the injection hole 22 is circular with a diameter of 0.30 mm here. Here, the number of injection holes 22 is 3 in the cylinder (axial) direction and 2 in the periphery of the cylinder, ie, 6 in total.

The outer cylindrical member 18 of the water ejector 6 is covered with a tubular covering member 26 on the outside, leaving the periphery (window portion) of the ejection hole 24 . The ejection holes 24 provided around the outer cylinder member 18 are slightly tilted from the tangential direction to the normal direction, and eject water in the direction of the ejection holes 24 . The ejection holes 24 eject water rotating in the rotation chamber 20 and cause the ejection water 25 to collide with the crushing member 8 .

The ejection hole 24 is formed in a direction in which the angle at which water is ejected from the ejection hole 24 is slightly deviated from the tangential direction, and the water in the rotation chamber 20 is ejected in this direction. The hole of the ejection hole 24 is circular and has a diameter of 0.15 mm, for example. The ejection holes 24 are provided in a plurality of stages above and below the outer cylinder member 18, and several locations are provided per stage so that the ejection water 25 does not interfere with each other. One or a plurality of water ejectors 6 are arranged near the central portion of the crushing member 8 . Note that the water ejector 6 is fixed to the bottom surface portion 30 of the storage container 9 .

The pulverizing member 8 is arranged around the water ejector 6 , and causes the jetted water 25 from the ejection hole 24 to collide with the pulverizing surface portion 32 to pulverize the water to generate the mist 7 . As the material of the pulverizing member 8, a metal material such as stainless steel, a light metal material such as aluminum, a synthetic resin material, or the like is used.
The crushing member 8 is cylindrical (here, cylindrical), and a crushing surface portion 32 is formed inside. The upper portion of the crushing member 8 is opened to form an opening 33 through which the mist 7 generated on the crushing surface 32 is emitted.

The storage container 9 is composed of a cylindrical side portion 29 and a flat bottom portion 30, and an edge portion 34 having an outwardly enlarged diameter is formed on the upper portion of the side portion 29. As shown in FIG.
A water ejector 6 is arranged in the vicinity of the central portion inside the storage container 9 and fixed to the bottom portion 30 . Also, a water supply pipe 4 from a water supply or the like is attached to the bottom portion 30 of the storage container 9 and connected to the inlet 14 of the water ejector 6 . In this case, since the water ejector 6 does not have a functional distinction between upper and lower sides, the inlet 14 is placed facing downward.
The storage container 9 stores water droplets and the like generated inside and discharges them from a drainage port provided in the bottom surface portion 30 . A disk-shaped plate member 31 is arranged on the upper part of the water ejector 6 to cover and protect the water ejector 6 .

As shown in FIG. 3, the particle size adjusting member 10 is annular (hollow disc-shaped) and is made of metal such as stainless steel, light metal such as aluminum, synthetic resin, or the like.
The annular portion of the grain size adjusting member 10 includes an adjusting surface portion 50 having a flat cross section and decreasing in diameter inward, a side surface portion 52 formed obliquely upward from the outer end portion, and a horizontally outward portion extending from the upper portion of the side portion 52. It has an annular face portion 54 formed in the . An outlet portion 56 for the mist 7 is formed inside the adjustment surface portion 50 .

As shown in FIG. 4, the particle size adjusting member 10 is arranged on the upper side of the crushing member 8 and above the flange member 12, and both are arranged with the same central portion.
In this case, the control surface portion 50 of the particle size adjusting member 10 protrudes inward from the crushing member 8 , so that the crushing surface portion 32 of the crushing member 8 and the inner peripheral portion of the control surface portion 50 of the particle size adjusting member 10 are aligned. A trapping portion (W) by the control surface portion 50 is formed in the range between them. This trapping site (W) has a ring shape with a constant width.

The particle diameter adjusting member 10 captures a large amount of the relatively large-diameter mist 7 by the capturing portion (W) of the adjusting surface portion 50 near the crushing surface portion 32, and the relatively small-diameter mist 7 that is not captured here is It is discharged to the outside from the outlet portion 56 of the control surface portion 50 .
As the particle size adjusting member 10, a plurality of types having different widths of the adjusting surface portions 50 are prepared, and the particle size (central particle size) of the mist 7 is adjusted by changing the width (radial direction) of each adjusting surface portion 50. . Changing the width of the adjusting surface portion 50 changes the width of the trapping portion (W), and the particle size of the emitted mist 7 is adjusted by changing the width of the trapping portion (W).

In this case, if the capture portion (W) of the particle size adjusting member 10 has a narrow width, the large-diameter mist 7 that mainly moves near the crushing surface portion 32 of the crushing member 8 adheres to the capture portion (W). The captured mist 7 (middle-sized, small-sized, fine-sized mist, etc.) is discharged into the air from the discharge port 56 of the particle size adjusting member 10 . In addition, if the width of the capturing portion (W) is widened, the mist 7 of medium diameter or the like that moves a little away from the crushing surface portion 32 can also be captured. is emitted.

The flange member 12 is annular (hollow disc-shaped) and made of the same material as the crushing member 8 . The flange member 12 has a flat, hollow disk-shaped receiving portion 38 formed inside the annular portion, and an inclined portion 40 extending obliquely upward from the outer peripheral portion of the receiving portion 38 and inclined from the outer peripheral portion. A flange surface portion 42 with a gentle angle is formed.
The main use of the flange member 12 is to use it as a pedestal for mounting the control surface portion 50 of the particle size control member 10 on the top. With the flange member 12, the particle diameter adjusting member 10 can be easily attached and detached, and the particle diameter adjusting member 10 can be accurately arranged.

FIG. 5 shows cross sections of the flange member 12 and the crushing member 8, etc. As shown in FIG. The crushing member 8 and the flange member 12 are molded separately, but here, both members are joined together and used as an integral unit. In this case, the peripheral portion 11 of the upper edge of the crushing member 8 and the inner peripheral portion 13 of the receiving portion 38 of the flange member 12 are joined with an adhesive or by welding, and the flange member 12 is placed above the crushing member 8. integrally formed. This is the form in which the crushing member 8 is formed like a skirt below the flange member 12 .

By integrating the crushing member 8 and the flange member 12, the positions of the particle size adjusting member 10 arranged on the upper part of the flange member 12 and the adjusting surface portion 50 thereof are accurately determined, and the center position of the crushing member 8 and the upper part thereof are accurately determined. , and the center position of the adjustment surface portion 50 coincides with each other, and the two are precisely overlapped.
Further, by integrating the crushing member 8 and the flange member 12 and providing the storage container 9 separately, the fixing and arrangement of the water ejector 6 and the crushing member 8 can be performed accurately, and the shape of the storage container 9 is relatively free. , and consideration can be given to the installation form of the mist generator 2 and the like.

The crushing member 8 is housed in the storage container 9 together with the flange member 12 , and the flange member 12 is arranged above the rim 34 of the storage container 9 . The flange member 12 is fixed to the edge portion 34 of the storage container 9 with screws or the like, and normally the flange member 12 is not removed from the storage container 9 .

Incidentally, the flange member 12 can also be used alone. For example, the crushing member 8 is arranged in the storage container 9 , the flange member 12 is attached to the upper edge portion 34 of the storage container 9 , and the particle size adjusting member 10 is arranged above the flange member 12 . Then, the crushing member 8 is arranged below the inner end of the receiving portion 38 of the flange member 12 . In this case, the inner end portion of the receiving portion 38 of the flange member 12 may be slightly bent downward, and the bent portion may be arranged to cover the upper edge of the crushing member 8 so that the two are engaged. .

Also, if the attachment and detachment of the particle diameter adjusting member 10 is not a problem, it is also possible to employ a configuration that does not use the flange member 12 . In this case, the particle size adjusting member 10 is arranged directly above the pulverizing member 8 . In this case, a bottom plate may be provided at the lower portion of the crushing member 8 to form a container shape, and the storage container 9 may not be used.

Next, the relationship between the water ejector 6 and the crushing members 8 arranged around it will be described. The cylindrical pulverizing member 8 has a water ejector 6 arranged in its central part, and jetted water 25 ejected from an ejection hole 24 of the pulverizing member 8 hits the pulverizing surface portion 32 of the pulverizing member 8 to pulverize to generate mist 7. . The mist 7 generates an air current by means of the jet of the jet water 25 and the momentum of the pulverization. Further, during pulverization on the pulverizing surface portion 32 , part of it becomes water droplets (surplus water) and falls on the pulverizing surface portion 32 . By applying a water-repellent finish to the pulverized surface portion 32, the generation efficiency of the mist 7 is enhanced (surplus water is reduced).

When the crushing member 8 is cylindrical, a crushing surface portion 32 is formed around it, so a plurality of water ejectors 6 can be arranged inside, and the amount of mist 7 generated can be increased. Further, when the crushing member 8 has a cylindrical shape with a circular cross section, the diameter of the crushing member 8 is preferably in the range of 10 cm to 40 cm, or 20 cm to 30 cm, in order to prevent generation of turbulence. be.

The water ejector 6 is arranged at a position near the center of the opening 33 of the crushing member 8, and is fixed to a base or the like provided on the bottom surface 30 of the storage container 9. As shown in FIG. When it is desired to increase the amount of mist 7, a plurality of water ejectors 6 are arranged. It is preferable that the number of water ejectors 6 is about two or three in consideration of interference between jets. The angle at which the jet water 25 strikes the pulverizing surface portion 32 is preferably in the range of 50 to 90 degrees with respect to the surface of the pulverizing surface portion 32 .
According to the test, after the ejected water 25 is ejected from the ejection hole 24, separation into water droplets starts from the ejection position of about 15 mm, the distance between the droplets increases to about 30 mm, and when it exceeds 30 mm, the distance between the droplets becomes constant. Become. Therefore, the distance from the ejection hole 24 to the pulverizing surface portion 32 of the pulverizing member 8 (flight distance of the ejected water 25) is practically in the range of 20 mm or more and 500 mm or less, or 30 mm or more and 200 mm or less.

Here, each arrangement form of the crushing member 8, the flange member 12, and the particle size adjusting member 10 will be described. The flange member 12 and the crushing member 8 are integrated with each other.
Even if the crushing member 8 and the flange member 12 are not integrated, there is no particular difference in function.

As also shown in FIG. 4 , the flange member 12 is arranged above the rim 34 of the storage container 9 and attached so as to cover the upper part of the rim 34 . The flange member 12 is fixed to the edge portion 34 of the storage container 9 using screws or the like. Then, the particle size adjusting member 10 is arranged above the flange member 12 .
The outer peripheral portion (diameter) of the flange surface portion 42 of the flange member 12 is formed to be larger in diameter than the outer peripheral portion (diameter) of the edge portion 34 of the storage container 9 so that the flange member 12 is placed on the upper portion of the storage container 9. .

The particle size adjusting member 10 uses the flange member 12 as a pedestal, and is arranged so that the adjusting surface portion 50 of the particle size adjusting member 10 rests on the upper portion of the receiving portion 38 of the flange member 12 . With this arrangement, the particle diameter adjusting member 10 can be easily replaced (attached and detached).
Further, the flange surface portion 42 of the outer peripheral portion of the flange member 12 is formed larger than the outer peripheral portion of the annular surface portion 54 of the particle size adjusting member 10 so that the particle size adjusting member 10 can be arranged with a margin. The reason why the flange member 12 covers the outer peripheral portion of the particle size adjusting member 10 in this way is to prevent the particle size adjusting member 10 from being moved, such as being lifted, and detached due to the wind pressure of the blower 64 or the like. .

The particle diameter adjusting member 10 is used for humidification, cooling, etc., and is replaced with another particle diameter adjusting member 10 every season. For this reason, the particle size adjusting member 10 is placed and mounted on the upper portion of the flange member 12, and is detachably attached so that it can be easily and freely detached for replacement or the like.
The particle size adjusting member 10 is placed on the upper portion of the flange member 12 and is arranged in a state of covering a part of the inside of the periphery of the opening 33 of the crushing member 8 . The particle diameter adjusting member 10 is mounted on the upper portion of the flange member 12 .
As for the detachable form of the particle diameter adjusting member 10, for example, the self-weight of the particle diameter adjusting member 10 may be used, and the particle diameter adjusting member 10 may be placed as it is on the upper portion of the flange member 12 without being fixed. Alternatively, the particle size adjusting member 10 may be lightly attached or hooked to the flange member 12 so that attachment and detachment thereof can be easily performed.

For example, a portion of the adjusting surface portion 50 of the particle size adjusting member 10 is placed on the upper portion of the receiving portion 38 of the flange member 12, and the particle size adjusting member 10 is fixed to the flange member 12 using screws.
In this case, for example, elongated holes 51 are formed at a plurality of locations (for example, three locations) on the adjusting surface portion 50 of the particle diameter adjusting member 10, and screws are lightly inserted into the screw holes 39 provided in the receiving portion 38 of the corresponding flange member 12. screw on. Then, an enlarged diameter portion is formed at one end of the elongated hole 51, the head of the screw is fitted into the enlarged diameter portion of the elongated hole 51, the particle diameter adjusting member 10 is rotated slightly, and the screw head is The long hole 51 is locked. In this case, the particle size adjusting member 10 is more strongly fixed to the flange member 12 by tightening the screws. Thus, the particle size adjusting member 10 is lightly fixed to the upper portion of the flange member 12 and is detachably attached.

Here, the operation of generating the mist 7 in the mist generator 2 will be described.
As shown in FIG. 2, due to the rotation of the water in the rotating chamber 20 of the water ejector 6, a velocity component dependent on the angular velocity of the swirl flow is added to the velocity component dependent on the water pressure in the rotating chamber 20, resulting in a rotating water flow 28. and increase the initial velocity of the jet water 25 jetted from the jet hole 24. - 特許庁
The jet water 25 jetted from the jet hole 24 is jetted at high speed with the momentum of the rotating water flow 28. Immediately after jetting, the jet water 25 flies in the air in a linearly continuous shape. As a result, the water droplets gradually become intermittent and eventually become almost spherical water droplets.

When the water droplets of the ejected water 25 collide with the crushing surface portion 32 of the crushing member 8, the water droplets are exploded and crushed on the surface of the crushing surface portion 32 to be misted and dispersed in the air as mist 7 (fog). Moreover, the surplus water that is not turned into mist flows downward from the pulverization surface portion 32 and is stored in the bottom surface portion 30 of the storage container 9 .
The particle size of the mist 7 depends on the collision speed of the water droplets, etc. The higher the speed, the smaller the particle size (average). Also, in order to generate the mist 7 with a particle size of 10 to 30 microns (μm) called dry mist, it is effective to hit the pulverizing member 8 with jet water 25 in the form of droplets. The water droplets that have collided with the crushing member 8 (crushing surface portion 32) are crushed and diffused as mist 7 (fog) and dispersed in the air.

Further, according to the mist generator 2, under the condition of the water pressure of normal tap water, the water droplets from the jet water 25 collide with the crushing member 8 at high speed, and are called dry mist with a diameter of about 10 to 30 microns. , it has been confirmed to produce mist 7 with a wide range of particle sizes up to about 100 microns wet, which can be generated with low-cost water pressure nozzles.
In this case, an air current is generated due to the flight of the jet water 25 jetted from the jet hole 24 and the diffusion of the mist 7 due to pulverization on the pulverization surface portion 32 . This air current becomes an upward air current from near the periphery of the crushing member 8, and the generated mist 7 rides on this air current and rises.

Next, the effect of adjusting the particle size of the mist in the mist generator 2 will be described.
As shown in FIG. 6, jet water 25 is discharged from the water jet device 6, and when this collides with the crushing surface portion 32 of the crushing member 8, mist 7 of various sizes is generated. At the same time, the jet stream of the jet water 25 generates an air flow in the peripheral direction inside the cylindrical crushing member 8, which is affected by the inner surface of the crushing member 8, and the air current due to the force of crushing on the crushing surface portion 32, etc. rises or has an inner velocity vector, and then flows out from the opening 33 and the discharge port 56 .

The generated mist 7 has a velocity vector in the direction along the cylindrical wall surface of the pulverizing member 8. In this case, the mist 7 with a smaller diameter is more likely to be affected by the generated airflow in the direction of the opening 33. Therefore, the small-diameter mist 7 flows toward the center of the pulverizing member 8, rises, and is discharged from the opening 33 and the discharge port 56 to the outside.
On the other hand, the relatively large mist 7 rising near the inner wall surface of the pulverizing member 8 is adsorbed (adhered) and captured by the capturing portion (W) of the upper particle size adjusting member 10 .

By appropriately setting the width of the trapping portion (W) of the control surface portion 50 according to the properties of the flow of the mist 7, the particle size of the mist 7 that can be trapped by the trapping portion (W) is determined. Therefore, it is possible to adjust the particle size of the mist 7 discharged from the discharge port 56 to the outside without being captured to a desired size.
That is, when the width of the trapping portion (W) of the particle size adjusting member 10 is narrow (large inner diameter), the particle size of the mist 7 emitted to the outside is large, and when the same width is wide (small inner diameter), The particle size of the ejected mist 7 becomes smaller, which makes it possible to change the particle size distribution (central particle size band) of the ejected mist 7 .

As for the properties of the mist 7, the vaporization speed or humidifying ability of the mist 7 is mainly determined by the number of particles with the maximum particle size of the mist 7. Therefore, the mist 7 can be used for different purposes such as humidification and cooling depending on the particle size. Therefore, as shown in FIG. 7, a plurality of types of particle diameter adjusting members 10 (A, B, C, and D) with different inner diameters of the particle diameter adjusting member 10 are prepared, and these are exchanged for use. Therefore, it is possible to adjust the particle diameter (central particle diameter) of the emitted mist 7, and the mist 7 can be easily generated according to each application such as cooling or humidification.

Here, the effect of adjusting the particle size of the mist 7 in the particle size adjusting member 10 will be specifically described.
The particle diameter adjusting member 10 is arranged above the crushing member 8. At this time, the inner circumference of the upper portion of the crushing member 8 is covered with the adjusting surface portion 50, and this portion is a capturing portion (W) that captures the mist 7. becomes. The trapping portion (W) of the control surface portion 50 is the lower surface portion 49 of the control surface portion 50 of the particle diameter control member 10 and is a portion that protrudes inward from the crushing surface portion 32 that is the inner peripheral surface of the crushing member 8 .

The control surface portion 50 of the particle diameter control member 10 has a ring shape with a constant width, and the inner diameter of the control surface portion 50 is also constant. is formed. Of the mist 7 moving upward, the mist 7 having a relatively large particle size is attached to the capturing portion (W) and captured, and turned into water droplets. Conversely, the mist 7 (relatively small in particle size) not captured at the capture site (W) is discharged from the discharge port 56 to the outside, and the particle size of the mist 7 is adjusted.

As shown in FIG. 4 and the like, the width of the trapping portion (W) of the particle size adjusting member 10 is specifically determined by the inner diameter (P) of the cylindrical crushing member 8 and the adjusting surface portion 50 of the particle size adjusting member 10. 1/2 of the difference from the inner diameter (Q) of the trapping site (W) (=(PQ)/2). For this reason, a trapping portion (W) having a predetermined width is formed between the inner diameter of the adjusting surface portion 50 of the particle size adjusting member 10 and the inner diameter of the cylindrical crushing member 8, and the central opening of the crushing member 8 is formed. An outlet 56 for mist 7 is formed at 33 .

When the mist 7 generated by the crushing member 8 rises, the mist 7 with a relatively large particle size moves near the crushing surface 32, and the mist 7 with a relatively small particle size moves away from the crushing surface 32. . These phenomena are considered to be due to the influence of the weight of the mist 7 due to the particle size, the air resistance, etc. Similar movements of the mist 7 have been confirmed in in-house tests.
In addition, the large particle size mist 7 or the like generated by the pulverization of water on the pulverization surface portion 32 descends without riding on the air current, or adheres to the pulverization surface portion 32, and flows directly to the bottom portion 30 of the storage container 9 for collection. be done.

Therefore, here, as the particle size adjusting member 10, a hollow disk-shaped (annular) molded member having a predetermined capturing portion (W) around the entire circumference is used, and this is placed above the crushing member 8 to capture According to the width of the portion (W), the particle size of the mist 7 that can be captured and removed was adjusted, and the particle size (central particle size) of the mist 7 emitted to the outside was adjusted.
The mist 7 generated by pulverizing the pulverizing member 8 of the mist generator 2 is finer than the fine mist, and the particle size of the central zone is 30 μm to 50 μm, and part of the mist is 10 μm to 30 μm. Dry mist or mist 7 with a particle size of 50 μm or more is also generated. Therefore, when the particle diameter of the mist 7 is not adjusted, the mist 7 with various particle diameters is emitted to the outside.

Now, when the upper portion of the crushing member 8 is covered with the adjusting surface portion 50 of the particle size adjusting member 10, the mist 7 having a large particle size among the mist 7 generated and rising on the crushing surface portion 32 is near the inner peripheral portion of the crushing member 8. At that time, the relatively small diameter mist 7 that is prevented from rising by the adjusting surface portion 50 and adheres to its lower surface portion is captured, turned into water droplets and stored inside, and the relatively small diameter mist 7 that is not captured passes through the discharge port portion 56. It passes through and is released to the outside.
For this reason, the particle size adjusting member 10 having a different inner diameter of the adjusting surface portion 50, that is, having a different width of the inward projection (capturing portion (W)) is prepared. By switching (replacement) the inner diameter standard of the control surface portion 50 in the particle size control member 10, the particle size of the mist 7 captured by the control surface portion 50 and the particle size of the mist 7 emitted from the discharge port portion 56 are changed. adjust the

Therefore, for example, if two types of particle size adjusting member 10 are prepared, one having a narrow capturing portion (W) and the other having a wide capturing portion (W), two types of mist 7 having different particle sizes can be obtained by exchanging these. It can be generated and released. It should be noted that the particle size of the mist 7 adjusted here is the maximum particle size of the emitted mist 7 and the average particle size of the mist 7 .
In addition, by preparing a plurality of particle size adjusting members 10 having adjusting surface portions 50 with different inner diameters, it is possible to generate mist 7 having a plurality of types of particle sizes. Of course, if the particle size adjusting member 10 is of one type, the mist 7 having the particle size adjusted to one type is generated.

Here, the result of the measurement evaluation of the practical mist generator 2 will be described. As the mist generator 2, one having the following specifications was used.
The crushing member 8 has a cylindrical shape and an inner diameter (P) of 220 mm. Here, four types of particle size adjusting members 10 are used, all of which have the same basic shape, but differ in the inner diameter (Q) of the adjusting surface portion 50 . Based on the inner diameter (Q) of these particle size adjusting members 10, the particle size of the emitted mist 7 was adjusted and observed.
Incidentally, the height (H) of the crushing member 8 is about 52 mm.

Specifically, as shown in FIG. 7, the inner diameter (Q1) of the adjusting surface portion 50 of the particle diameter adjusting member 10(A) is 183 mm, the inner diameter (Q2) of the particle diameter adjusting member 10(B) is 193 mm, and The inner diameter (Q3) of the diameter adjusting member 10(C) is 197 mm, and the inner diameter (Q4) of the particle diameter adjusting member (D) is 214 mm.
Further, the height position at which the jet water 25 from the water ejector 6 collides with the crushing surface portion 32 of the crushing member 8 is 20 to 30 mm (average 25 mm) downward from the upper edge of the crushing member 8 .

From this, the size (width) of the capture portion (W) formed by the control surface portion 50 of each particle size control member 10 (A to D) is as follows. where the capture site (W) = (P-Qn)/2.
(1) Particle size adjusting member (A) Q1 = 183 mm Capture portion (W) = 18.5 mm
(2) Particle size adjusting member (B) Q2 = 193 mm Capture site (W) = 13.5 mm
(3) Particle size adjusting member (C) Q3 = 197 mm Capture portion (W) = 11.5 mm
(4) Particle size adjusting member (D) Q4 = 214mm Captured portion (W) = 3.0mm

According to the above measurement and evaluation, the relationship between the trapping portion (W) of the particle size adjusting member 10 and the median particle size band (μm) of the mist 7 discharged from the discharge port 56 is as follows.
(W) (Center particle size range) (Application)
(1) Particle size adjusting member (A) 18.5mm 20-40μm for humidification (weak)
(2) Particle size adjusting member (B) 13.5mm 30-50μm for humidification (medium)
(3) Particle size adjusting member (C) 11.5mm 40-60μm Humidification (strong)
(4) Particle size adjusting member (D) 3.0mm 50-80μm For cooling (5) No particle size adjusting member - 100μm or more Simple watering

Regarding each particle size adjusting member 10, when using a wide trapping portion (W) (narrow discharge port 56), the mist 7 having a minimum particle size of relatively small diameter (for example, 40 μm) or more is large. Most of the mist 7 that is captured and removed and discharged from the discharge port 56 has a particle size of 40 μm or less.
In addition, when the trapping portion (W) is narrow (the discharge port 56 is wide), a large amount of the mist 7 having a minimum particle size of relatively large diameter (for example, 50 μm) or more is captured and removed, and the discharge port Most of the mist 7 emitted from 56 has a particle size of 50 μm or less.

As described above, the particle diameter of the mist 7 to be discharged actually has a range of particle diameters, and the particle diameter of the mist 7 to be discharged is precisely the central particle diameter band or the central particle diameter. Here, the median particle size band (μm) is the median particle size, and the mist 7 having a particle size smaller than that or the mist 7 having a particle size larger than that is also slightly included.
From this, as a result of the test, the particle size of the mist 7 to be emitted was determined to be in the median particle size range (example 20-40 μm).

In addition, as the above (application), humidification (weak) is likely to get wet if the room temperature is relatively low and the mist particle size is large, such as a greenhouse in winter. is used in a greenhouse in early autumn or early summer, when the temperature is slightly lower than the peak temperature, but a certain amount of humidification is required.
From the above test results, it is preferable that the width of the capture portion (W) is in the range of 10 mm to 20 mm when used for humidification, and 3 mm to 6 mm, or 3 mm to 10 mm when used for cooling. .
Elements such as the height position at which the jetted water 25 collides with the crushing surface portion 32 of the crushing member 8 are also related to particle size adjustment, but this height position is substantially fixed due to the structure of the water ejector 6 and the like. Therefore, the width of the trapping portion (W) is a practically appropriate value.

The capture site (W) is determined by the difference (=(PQ)/2) between the inner diameter (P) of the crushing member 8 and the inner diameter (Q) of the particle size adjusting member 10, and the capture site (W) is It does not depend on the size of the inner diameter (P) of the crushing member 8 itself.
Further, it has been confirmed that the air flow inside the pulverizing member 8 is formed by jet flow or the like generated from the water 25 jetted from the water jet device 6 . It is believed that the particle size of the mist 7 captured at the capturing portion (W) is determined by the relationship between the height position at which the jet water 25 collides with the crushing surface portion 32 and the inner diameter (Q) of the particle size adjusting member 10. Similar results have been obtained in tests.
However, the capture site (W) is determined by the practical range of the inner diameter (P) of the crushing member 8, the appropriate range of the movement distance until the jet water 25 from the water ejector 6 reaches the crushing member 8, etc. It is appropriate and practical to keep it within a certain range from .

The mist 7 generated from the mist generator 2 can be used for cooling and humidification in agriculture (greenhouses, etc.), for example. Since cooling applications are required in summer, the particle size adjusting member 10 mainly has a narrow trapping region (W) (particle size adjusting member (≡), etc.), and in winter it is used for humidification. Since the application is required, one with a wide trapping site (W) (particle size adjusting member (A to C), etc.) is used.
For this reason, if a plurality of types, for example, two to four types, having different inner diameters (widths of the trapping portions (W)) of the controlling surface portion 50 are prepared as the particle size controlling member 10, they can be easily adjusted according to the application depending on the weather and the like. can be used properly.

Four types of particle size adjusting members 10 are used here, but one or more types can be used. For example, two types of particle size adjusting members 10 are used for humidification and cooling, and three Examples include a mode in which different types of particle size adjusting members 10 are used for humidification (strong), humidification (weak), and cooling.
By exchanging and using these particle size adjusting members 10 properly, the particle size adjusting member 10 that emits a large amount of mist 7 having a relatively large particle size with a high cooling effect is used in the summer, and the particle size adjusting member 10 that emits a large amount of mist 7 with a relatively large particle size with a high humidifying effect is used in the winter. The particle size of the mist 7 can be appropriately adjusted, for example, by using a particle size adjusting member 10 that releases a large amount of the mist 7 having a small particle diameter.

Next, here, regarding the flange member 12 of the mist generating device 2, the mist 7 adheres to the storage container 9 or the like and becomes water droplets, which fall down. explain.
Normally, when the flange member 12 is not provided, a portion of the mist 7 adheres to the outer peripheral portion (the edge portion and the vicinity of the edge portion) of the storage container 9 due to the flow of the mist, and forms water droplets. The water droplets travel along the outer circumference of the storage container 9, collect on the rear surface side of the bottom surface portion 30, and drop downward.
As a countermeasure against this, the outer peripheral portion (diameter) of the flange member 12 is formed to be larger in diameter than the outer peripheral portion (diameter) of the edge portion 34 of the storage container 9 . Then, the flange member 12 forces the mist 7 to adhere to the outer periphery of the flange member 12 (flange surface portion 42, inclined portion 40, etc.) to form water droplets, which are stored in the receiving container 9.

FIG. 8 explains how the flange member 12 prevents dripping of water droplets. The flange member 12 is arranged so as to cover the upper portion of the edge portion 34 of the storage container 9 . In practice, a small gap is provided between the flange member 12 and the edge 34 .
The flange surface portion 42 on the outer periphery of the flange member 12 is formed to have a larger diameter than the edge portion 34 forming the outer periphery of the storage container 9, so that the outer peripheral portion of the storage container 9 is covered by the flange member 12 when viewed in plan. It is a hidden form. Further, the receiving portion 38 forming the inner periphery of the flange member 12 is connected at its inner end portion to the crushing member 8 arranged in the storage container 9 .

Here, when the jet water 25 from the water jet device 6 is applied to the grinding surface portion 32 of the grinding member 8 and pulverized to generate the mist 7, the mist 7 rises by the jet water 25 and the momentum of the pulverization, and further upwards. is diffused in After that, the temperature of the mist 7 is lower than the temperature of the surroundings, so it starts to fall, and it evaporates on the way and cools the surroundings. Arrows in the drawing indicate the movement (flow path) of part of the mist 7 .
When the mist 7 rises, diffuses, and descends, part of the mist 7 adheres to the outer peripheral portion (flange surface portion 42, inclined portion 40) of the flange member 12, etc., and the mist 7 adhered and captured grows. water droplets (condensation).

Water droplets 60 from the mist 7 descend from the back and front surfaces of the flange member 12 along slopes such as the inclined portion 40 , and eventually enter the gap between the edges 34 of the storage container 9 . The particles are drawn inward (capillary action), pass through the inner surface of the storage container 9 or the outer surface of the crushing member 8 and are stored in the bottom surface 30 of the storage container 9 . Also, some of the water droplets pass through the gap between the flange member 12 and the particle diameter adjusting member 10 and are similarly accommodated.
As a result, the mist 7 is prevented from adhering to the outer peripheral portion of the storage container 9 itself and forming water droplets, and the droplets do not drop (drip), thereby preventing the lower part from getting wet.

The mist generator 2 is particularly suitable for use indoors, for example, in a greenhouse for growing plants (fruits, vegetables, etc.). When the mist generator 2 is used in a greenhouse, the blower 64 is used to diffuse the mist 7 and average the temperature and humidity distributions in the room to prevent unevenness.

FIG. 9 shows a form in which a blower 64 is installed near the mist generator 2 and the generated mist 7 is moved and diffused within a predetermined range together with the airflow of the blower 64 .
As for the positional relationship between the blower 64 and the mist generator 2, the mist generator 2 is arranged in front of the blower 64 (the side where the air is pushed out). Theoretically, the mist generator 2 may be placed behind the blower 64, but in this case, the mist 7 is sprayed as designed behind the blower 64 because the airflow in the vicinity is uncertain. In addition, there is a concern that the mist 7 passing through the blower 64 may deteriorate the blower 64 such as rust.

The blower 64 mixes the mist 7 on the forward air current and conveys it, and emits and diffuses the mist 7 to the surroundings.
Normally, a room such as a greenhouse is elongated in one direction. Therefore, for example, the mist generator 2 is arranged at one end of the greenhouse together with the blower 64, and if the room is large, it is further arranged at the center or the like. and move and diffuse the mist 7.
Since the mist generating device 2 does not use power or the like, it has a simple structure, is inexpensive (initial investment, operating cost, etc.), can be used easily, and has good durability. For this reason, especially when cultivating plants such as fruits (strawberries, etc.), vegetables (tomatoes, mushrooms, etc.), flowers, etc. in greenhouses, etc., it is useful for managing their growing environment, etc., and can be expected to have utility value.

Therefore, according to this embodiment, the size of the mist particle size can be adjusted with a simple configuration, and handling is easy, operability and convenience are excellent. This has the effect of preventing dripping of water droplets from the device.
In addition, the external environment of the greenhouse changes greatly depending on the season, but by adjusting the particle size of the mist from the mist generator according to this, the temperature and humidity inside the greenhouse can be controlled to suitable conditions. It is possible to provide a suitable growth environment for each plant such as cultivated agricultural plants and flowers.
