(Embodiment 1)
The mist generator according to Embodiment 1 of the present invention will be described below. FIG. 1 is a schematic cross-sectional view of a humidifier equipped with a mist generator according to Embodiment 1 of the present invention. As shown in the figure, a hollow cylinder is formed inside a main body 1 of the humidifier and a bottom surface is formed in an inverted conical shape. The mist transport duct 2 is disposed, and a drain port 3 is opened at the center of the inverted conical bottom surface of the mist transport duct 2. A hollow cylindrical mist generating cylinder 4 is disposed substantially concentrically with the mist transport duct 2 inside the mist transport duct 2. The lower end of the mist generating cylinder 4 is provided with a space so that air can communicate with the mist conveying duct 2, and the other end of the mist generating cylinder 4 communicates with a suction port 5 opened in the outer shell of the main body 1. Yes.

  Further, a fan 6 is disposed inside the main body 1 so that the suction side communicates with the upper opening end of the mist transport duct 2, and the blowout side of the fan 6 communicates with the air outlet 7 opened on the top surface of the main body 1. is doing. Therefore, when the fan 6 is operated, the target air is sucked from the suction port 5, flows through the mist generating cylinder 4, flows through the space between the mist transport duct 2 and the mist generating cylinder 4, and is discharged from the outlet 7 to the outside of the main body 1. The air blowing operation is performed.

  In addition, a disk-shaped rotating plate 8 is disposed inside the mist generating cylinder 4, and a drive motor 9 is disposed above the rotating plate 8. The drive shaft of the drive motor 9 is connected to the central portion of the rotary plate 8, and the rotary plate 8 is configured to rotate by driving the drive motor 9. Further, the rotating plate 8 and the drive motor 9 are set in a positional relationship in which the rotating surface when the rotating plate 8 is rotated is parallel to the radial direction of the mist generating cylinder 4. Further, a plurality of annular collision walls 13, which will be described in detail later, are disposed inside the mist generating cylinder 4 and in the radially outward direction of the rotating plate 8.

  Further, a water supply pipe 10 for supplying water to the rotating surface of the rotary plate 8 is provided in the main body 1, and this water supply pipe 10 has one end opened above the rotary plate 8 and the other end is provided with the other end. It is connected to the discharge side of the water supply pump 11. The suction side of the water supply pump 11 opens into a water supply tank 12 disposed at the bottom of the main body 1, and the drain port 3 of the mist transport duct 2 opens above the water supply tank 12. Therefore, when the water supply pump 11 is operated with water stored in the water supply tank 12, the water in the water supply tank 12 is pumped up by the water supply pump 11 and supplied to the rotating plate 8 through the water supply pipe 10. When the rotating plate 8 is rotated by the drive motor 9 in this state, the water supplied on the rotating surface is discharged radially outward by centrifugal force and collides with the plurality of annular collision walls 13. Then, the water droplets further released from the annular collision wall 13 in the radially outward direction adhere to the inner wall surface of the mist generating cylinder 4 and drop downward through the wall surface and are collected from the drain port 3 to the water supply tank 12. Become.

  Next, details of the annular collision wall 13 will be described. 2A is a schematic enlarged view of the annular collision wall 13, and FIGS. 2B, 2C, 2D, 2E, and 2F are illustrated in FIG. It is a schematic sectional drawing which shows the cross-sectional shape pattern of AA 'cross section of). As shown in FIG. 2 (a), the annular collision wall 13 is arranged in multiple layers concentrically with the rotation plate 8 on the radially outer peripheral side of the rotation plate 8. The cross-section viewed from the direction, that is, the AA ′ cross-sectional shape is an uneven shape as shown in FIG. 2 (b), a comb-like shape as shown in FIG. 2 (c), and a sawtooth as shown in FIG. 2 (d). The lightning shape as shown in FIG. 2 (e) and the wave shape as shown in FIG. 2 (f). By setting it as such a shape, the corner | angular part with respect to the radial direction of the rotating plate 8 will increase. In this corner portion, the contact portion with respect to the liquid radiated outward from the rotating plate 8 is small, and the liquid colliding with the corner is likely to scatter while maintaining the speed. Will be promoted by mist.

  In addition, at least some of the plurality of annular collision walls 13 from the inside are connected by connecting ribs 14 that are formed radially with the rotation axis of the rotating plate 8 as the center. As shown in FIG. 2A, the connecting ribs 14 that connect each of the plurality of adjacent annular collision walls 13 are not formed on the same straight line in the radial direction, and further go outward from the rotating plate 8 in the radial direction. Accordingly, the number of the connecting ribs 14 is increased to form a mesh shape. By adopting such a configuration, it is possible to suppress the water that has been diffused from the rotating plate 8 and has contacted the annular collision wall 13 from moving radially outward along the connecting ribs 14 and inhibiting mist formation.

  Next, details of the connecting rib 14 will be described. FIG. 3A, FIG. 3B, FIG. 3C, FIG. 3D, and FIG. 3E are schematic cross-sectional views showing a cross-sectional shape pattern of the axial cross section of the connecting rib. Similarly to the annular collision wall 13, the connecting rib 14 is preferably configured to have a shape with many corners for refining the collided liquid. 3 (a), comb teeth shown in FIG. 3 (b), sawtooth shapes shown in FIG. 3 (c), lightning shapes shown in FIG. 3 (d), and shown in FIG. 3 (e). By setting it as a wave shape, the corner | angular part with respect to the rotation direction of the rotating plate 8 will increase. In this corner portion, the contact portion with respect to the liquid diffused between the rotating plate 8 and the annular collision wall 13 and between the plurality of annular collision walls 13 is small, and the liquid colliding with the corner easily scatters while maintaining the speed. Then, the liquid is effectively miniaturized at the corners to promote mist formation.

  Next, the principle of mist generation will be described in detail. FIG. 4 is a schematic diagram showing an outline of the action in the mist generating cylinder 4. When the water supply pump 11 is operated as described with reference to FIG. 1, water is pumped from the water supply tank 12 by the water supply pump 11 and supplied to the water supply pipe 10. The outlet of the water supply pipe 10 is disposed above and near the center of the rotating plate 8 and is configured to supply water pumped up from the water supply tank 12 to the vicinity of the rotating shaft of the rotating plate 8. Here, when the drive motor 9 is driven to rotate the rotating plate 8, the supplied water is dissipated in a tangential direction from the outer peripheral edge of the rotating plate 8 by centrifugal force, and collides with the annular collision wall 13 in a stepwise manner. . That is, the water diffused from the point 15 shown in FIG. 4 scatters in the direction indicated by the arrow 16. The water droplets scattered in the direction of the arrow 16 collide with the innermost annular collision wall 13 that rotates together with the rotating plate 8. Due to this collision, the water droplets are crushed and fine mist is generated.

  Since the annular collision wall 13 is rotated together with the rotating plate 8 by the connecting rib 14, further centrifugal force is applied to the water droplet colliding with the innermost annular collision wall 13. The centrifugal force further increases the speed of the water droplet in the radially outward direction and is dissipated from the innermost annular collision wall 13 as indicated by an arrow 17, and then collides with the next outer diameter annular collision wall 13 to be fine. Turn into. That is, by rotating both the rotating plate 8 and the annular collision wall 13, centrifugal force is applied to water droplets radiating from the annular collision wall 13, and the collision energy at the time of collision with the next annular collision wall 13 is increased to refine the structure. Can be promoted.

  Further, residual water remaining on the annular collision wall 13 that is not diffused into the air as a fine mist by the collision is subjected to centrifugal force due to the rotation of the annular collision wall 13, and as shown by an arrow 18, It is diffused from the outer periphery again in the radially outward direction. In this way, new water droplets diffused again from the annular collision wall 13, a part of the water droplets diffused from the rotating plate 8 and not collided with the annular collision wall 13, and the innermost annular collision wall 13 A part of the water droplets crushed by collision collides with the next annular collision wall 13 on the outer peripheral side, and is crushed and refined to generate mist.

  In addition, the rotating connecting rib 14 collides with water droplets that collide with the annular collision wall 13 and scatter, and the water droplets scattered between the plurality of annular collision walls 13 are also refined.

  Such an action is repeated in each of the plurality of annular collision walls 13 in the radially outward direction, and is repeated up to the outermost annular collision wall 13 among the rotating annular collision walls 13. . The water droplets diffused from the outermost annular collision wall 13 collide with the inner wall of the mist generating cylinder 4 as shown by an arrow 19 and become mist, and the residual water that has not been mist still forms along the inner wall of the mist generating cylinder 4. It is dripped and collected in the water supply tank 12 from the drain port 3.

  By the operations and actions described above, the water droplets diffused from the rotating plate 8 repeatedly collide and mist, and are accelerated by receiving the centrifugal force due to the rotation of the annular collision wall 13 every time the collision occurs. The mist can be generated by causing the water droplets scattered from the rotating plate 8 to collide with the annular collision wall 13 in a stepwise manner.

  When the fan 6 is operated in a state where mist is generated by the collision at the plurality of annular collision walls 13 as described above, the air outside the main body 1 is sucked from the suction port 5 as shown by the solid line in FIG. 4 is introduced. The air that has flowed into the mist generating cylinder 4 passes through the gaps between the plurality of annular collision walls 13 downward in the vertical direction and mixes in contact with the mist. The mixed air moves downward on the annular collision wall 13 on the leeward side, and further contact between the mist and air is achieved in this process. In this way, the mist and air contact each other at the gaps between the plurality of annular collision walls in the mist generating cylinder 4 and the leeward side thereof, and the mist is vaporized and the target air is humidified in this gas-liquid contact process. In addition, since the annular collision wall 13 rotates together with the rotating plate 8, the target air passing through the gaps between the plurality of annular collision walls 13 is subjected to a swirling action. This swirling action increases the contact time between the mist and the target air and increases the gas-liquid contact efficiency, so that the humidification efficiency is improved.

  The air that has passed through the mist generating cylinder 4 changes its flow direction rapidly from below to above as shown by the arrows in FIG. The air passes through the space and is sucked into the fan 6 and discharged from the air outlet 7 to the outside of the main body 1. As described above, the humidifying device performs the humidifying operation by generating mist in the mist generating cylinder 4, vaporizing the mist into the air introduced from the suction port 5, and discharging the mist from the outlet 7.

  FIG. 5 is a schematic cross-sectional view in the case where a plurality of, for example, three stages, the rotating plate 8 and the annular collision wall 13 are provided in the axial direction. As shown in the figure, through holes 20 for allowing the supply water to flow downward are opened in the uppermost and middle rotary plates 8. When water is supplied to the uppermost rotating plate 8 through the water supply pipe 10, a part of the water supply is diffused radially outward by the rotation of the rotating plate 8, and the remaining is passed through the through hole 20 and the middle rotating plate located below. Drip into 8. Similarly, a part of the dropped water is dissipated in the radially outward direction by the rotation of the rotating plate 8, and the rest passes through the through hole 20 and drops onto the lowermost rotating plate 8. All of the water dripped onto the lowermost rotating plate 8 is diffused outwardly by rotation. Water droplets diffused from each of the upper, middle, and lower rotating plates 8 collide with the annular collision wall 13 connected to each rotating plate 8 to be misted by the above-described action. As described above, a plurality of the rotating plates 8 and the annular collision wall 13 are provided in the axial direction, and the mist generation amount is increased because each of them performs mist formation of the water supply.

  Furthermore, since the air supplied into the mist generating cylinder 4 passes through the gap portion of the annular collision wall 13 formed in multiple stages in the axial direction in a stepwise manner in the axial direction, the gas-liquid contact portion and the gas-liquid contact time As a result, the humidification performance is improved.

  Due to the configuration, operation and action as described above, the mist generator in the present embodiment dissipates the liquid from the rotating plate 8 in the radially outward direction by centrifugal force, and is disposed concentrically on the outer peripheral side of the rotating plate 8. By causing the plurality of annular collision walls 13 to collide in stages, the liquid can be efficiently misted.

  The above description is merely an example for carrying out the present invention, and the present invention is not limited to the above embodiment.

  For example, although the shape of the annular collision wall 13 is concave and convex when viewed from the radial direction, water droplets diffused by rotation collide stepwise, and the corner portion having a large contribution to crushing at the time of collision increases. Any other shape may be used as long as it has a shape.

  Similarly, the shape of the connecting rib 14 may be any other shape as long as it has a function of causing water droplets diffused by rotation to collide stepwise and increasing a corner portion having a large contribution to crushing at the time of the collision.

  In addition, the above-described concave-convex, comb-tooth, saw-tooth, lightning, and wave-shaped formation intervals of the annular collision wall 13 and the connecting rib 14 are formed narrower toward the outer radial direction, that is, the innermost It is desirable to form the widest interval on the circumferential side and the narrowest interval on the outermost side. With such a shape, there is an effect that a decrease in the probability of collision of water droplets on the annular collision wall 13 and the connecting rib 14 in the radially outward direction with a large liquid diffusing area is suppressed, mist efficiency is improved, and humidification is performed. The effect of improving ability is obtained.

  Moreover, although the case where all the some annular collision walls 13 rotated was shown in the said embodiment, it is not necessary to rotate the annular collision wall 13 necessarily. For example, among the plurality of annular collision walls 13, at least one or more annular collision walls 13 are integrated and fixed with the inner wall of the mist generating cylinder 4 from the outside, and the remainder on the inner peripheral side is rotated integrally with the rotating plate 8. Alternatively, the entire annular collision wall 13 may be isolated from the rotating plate 8 and fixed.

  In the above configuration, the position where the rotary plate 8 and the annular collision wall 13 are arranged in the mist generating cylinder 4 is not mentioned, but as long as it is allowed for the restrictions such as the size of the main body 1, It is preferable to dispose the mist generating cylinder 4 on the leeward side of the annular collision wall 13, that is, to provide a larger space on the leeward side than the rotating plate 8 for vaporizing the mist and air in vapor-liquid contact with each other. Is desirable.

  Further, the outermost peripheral portion of the annular collision wall 13 and the inner wall of the mist generating cylinder 4 are sufficiently narrow so that the air passing through the mist generating cylinder 4 passes through the gap portions of the plurality of annular collision walls 13 almost without leakage. It is desirable that For example, when all of the plurality of annular collision walls 13 rotate, the distance between the outer peripheral edge of the outermost annular collision wall 13 and the inner wall of the mist generating cylinder 4 is such that the annular collision wall 13 does not contact the inner wall during rotation. For example, it is desirable to set a gap of about 5 mm. Further, among the plurality of annular collision walls 13, when at least one annular collision wall 13 is fixed from the outside, or from the outside, one or more annular collision walls 13 are integrated with the inner wall of the mist generating cylinder 4. In the case of rotating, the gap between the outermost annular collision wall 13 among the rotating annular collision walls 13 and the innermost annular collision wall 13 among the non-rotating annular collision walls 13 is rotated during the rotation. It is desirable to set an interval of, for example, about 5 mm so that the 13 do not contact each other.

  As described above, the mist generator according to the present invention can efficiently mist a liquid, and not only the portable humidifier shown in the embodiment, but also a humidified air cleaner, a bathroom sauna device, and relaxation by negative ions. The present invention can also be applied to devices, mist cooling devices, facial instruments, sprayers, and cleaning devices. In addition to hot water, the liquid to be mist can be applied to various liquids such as oil, solvent, and detergent.
