In such a conventional liquid miniaturization device, the water in the water storage portion is pumped by centrifugal force, and the pumped water is scattered from the pores vacated in the rotating body. In this principle, it is necessary to increase the diameter of the rotating body to secure centrifugal force in order to obtain the energy to pump the water in the water storage section and the energy to scatter the pumped water droplets from the pores, and as a result, the rotating body is large. There was a problem of becoming. Further, when such a liquid micronization device is applied to a liquid other than water, for example, sterilizing water containing hypochlorous acid, the viscosity of the liquid is higher than that of water, so that the liquid is less likely to be scattered from the pores, and further. There was a problem that a large rotating body was required. Further, as the size of the liquid miniaturization device increases, there is a problem that the size of the air purifier or the air conditioner using the device also increases.

Therefore, the present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a small liquid miniaturization device suitable for an air purifier or an air conditioner, which has improved pumping efficiency by centrifugal force.

In order to achieve this object, the liquid miniaturization device according to the present invention is a blower provided in a main body case having an intake port and an air outlet and an air passage connecting the intake port and the air outlet in the main body case. If, Ru with a liquid miniaturization chamber provided in the wind path between the blower and the air outlet.

As described above, the present invention provides a spiral groove or projecting piece inside the pumping pipe to generate a pumping force utilizing the frictional force between the inner wall surface of the pumping pipe and the water pumped by the pumping pipe. It is possible to increase the amount of pumped water in the pumping pipe. In addition, since the centrifugal force for pumping the required amount of water can be suppressed, the diameter of the pumping pipe can be reduced and the number of rotations of the pumping pipe can be reduced, and the size is smaller and suitable for an air purifier or an air conditioner. It provides an energy-saving liquid miniaturization apparatus.

The liquid miniaturization chamber is provided with a liquid miniaturization chamber provided in the air passage, and the liquid miniaturization chamber includes a collision wall having an upper opening and a lower opening, a rotating device provided in the collision wall, and water storage in the lower part of the collision wall.

It has a structure provided with a spiral groove or a projecting piece.

The water inside the pumping pipe is rotated by the rotation of the pumping pipe, and receives centrifugal force in the direction away from the rotation axis of the pumping pipe. The water that receives the centrifugal force and the reaction force from the surface of the pumping pipe is sucked up vertically above the rotation axis along the inner wall of the pumping pipe. Furthermore, since a spiral groove or projectile that is continuous from the lower part to the upper part of the inner surface of the pumping pipe is provided, water can be pumped from the water storage portion by rotating the spiral groove or projectile, and pumping water.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a schematic cross-sectional view of a liquid miniaturization device according to an embodiment of the present invention. The main body case 1 is provided so as to communicate with an intake port 2 for taking in air, a blower 4 for blowing air into the main body case, a liquid miniaturization chamber 5 connected to the air outlet of the blower 4, and a liquid miniaturization chamber 5. An air outlet 3 for discharging the generated air is provided. The air passing through the inside of the main body case 1 includes an intake port 2 for taking in air, a blower 4 for blowing air into the main body case, a liquid miniaturization chamber 5 connected to the air outlet of the blower 4, and a liquid miniaturization chamber 5. The air outlets 3 provided so as to communicate with each other move in this order.

The liquid miniaturization chamber 5 is provided with a collision wall 8 having an upper opening 6 and a lower opening 7. The collision wall 8 is provided by being fixed to the inner wall of the liquid miniaturization chamber 5. (Not shown)
Inside the liquid miniaturization chamber 5 surrounded by a collision wall 8, a tubular pumping pipe 9 for pumping water while rotating is provided. The pumping pipe 9 has an inverted conical hollow structure, and the rotating shaft 12 is fixed to the center of the inverted conical top surface. By connecting the rotary shaft 12 to the rotary motor 11 provided on the outer surface of the liquid micronization chamber 5, the rotational motion of the rotary motor 11 is conducted to the pumping pipe 9 through the rotary shaft 12 to rotate the pumping pipe 9.

As shown in FIG. 1, a water storage unit 10 for storing water is provided in the lower part of the liquid miniaturization chamber 5. The water surface area of the water storage unit 10 is larger than the opening area of the lower opening 7, and is about one-third to one-hundredth of the height of the cone of the pumping pipe 9, for example, a part of the lower part of the pumping pipe 9. The depth is taken so that the length of the tube is immersed. This depth can be designed according to the required pumping volume.

As a method of supplying water to the water storage unit 10, a known method can be used, for example, a method of directly supplying water from a water supply through a water pressure adjusting valve through a water supply pipe, or a method of supplying water from a water tank provided outside the liquid miniaturization chamber 5 in advance to a siphon. In principle, there is a method of pumping only the required amount of water. (Not shown)
As shown in FIG. 1, the pumping pipe 9 includes a plurality of rotating plates 13 formed so as to project outward from the outer surface of the pumping pipe 9. The plurality of rotating plates 13 are formed so as to project outward from the outer surface of the pumping pipe 9 at predetermined intervals in the axial direction of the rotating shaft 12. Since the rotating plate 13 rotates together with the pumping pipe 9, a horizontal disk shape coaxial with the rotating shaft 12 is preferable. The water droplets scattered from the rotating plate 13 fly in the space surrounded by the collision wall 8 and collide with the collision wall 8. At the same time, the gas passing through the liquid miniaturization chamber 5 also moves from the upper opening 6 to the inside of the collision wall 8 and moves from the lower opening 7 to the outside of the collision wall 8 while including water droplets crushed by the collision wall 8.

Since the kinetic energy of the water scattered from the rotating plate 13 is attenuated by friction with the air inside the collision wall 8, it is preferable that the rotating plate 13 is as close to the collision wall 8 as possible. On the other hand, as the collision wall 8 and the rotating plate 13 are brought closer to each other, the amount of air passing through the inside of the collision wall 8 decreases. Therefore, the lower limit of the distance is arbitrarily determined by the pressure loss and the amount of air passing through the inside of the collision wall 8.

Further, as shown in FIG. 1, the wall surface of the pumping pipe 9 is provided with an opening 14 penetrating the wall surface of the pumping pipe 9. The opening 14 of the pumping pipe 9 is provided at a position communicating with a rotating plate 13 formed so as to project outward from the outer surface of the pumping pipe 9. The radial size of the opening 14 needs to be designed according to the outer diameter of the portion of the pumping pipe 9 provided with the opening 14, and corresponds to, for example, 5% to 50% of the outer diameter of the pumping pipe 9. The diameter, more preferably, the diameter corresponding to 5% to 20% of the pumping pipe 9. Within the above range, the dimensions of each opening 14 may be the same.

As shown by the broken line in FIG. 1, the tubular pumping pipe 9 is provided with a spiral groove 15 on the inner surface of the pumping pipe 9. As the spiral shape, a known technique can be used, and for example, a spiral shape used for a screw pump called Archimedes' screw can be used.

FIG. 2 shows a state in which the opening 14 of the pumping pipe 9 and the spiral groove 15 are provided so as to be connected to each other. By connecting the opening 14 and the spiral groove 15, the water pumped by the spiral groove 15 can be efficiently discharged from the opening 14. Therefore, it is preferable that at least one of the openings 14 in contact with the rotating plate 13 is provided so as to be connected to the spiral groove 15 as shown in FIG. However, regardless of the spiral groove 15, the amount of water pumped on the inner wall surface of the pumping pipe 9 is also large. Therefore, it is not necessary to connect all the openings 14 to the spiral groove 15, and it is appropriate according to the required pumping amount. Can be designed.

As shown in FIG. 1, in the present embodiment, a configuration having a spiral shape from the lower part to the upper part of the pumping pipe 9 along the same direction as the rotation direction 16 of the pumping pipe 9 is illustrated. With such a configuration, the spiral groove 15 is rotated in the rotation direction 16 of the pumping pipe 9 by the rotation of the pumping pipe 9, and the water in the spiral groove 15 can be efficiently transported upward. Due to this effect, a larger amount of water than the conventional pumping pipe 9 can be pumped to the upper part of the pumping pipe 9. Therefore, the centrifugal force for pumping the required amount of water can be suppressed, the diameter of the pumping pipe 9 can be reduced, and the rotation speed of the pumping pipe 9 can be reduced.

FIG. 2 is an enlarged perspective view of the periphery of the opening 14. A part of the water pumped up along the inner surface of the pumping pipe 9 and the spiral groove 15 by the rotation is discharged to the outside of the pumping pipe 9 through the opening 14 and diffuses on the surface of the rotating plate 13. The water that has passed through the opening 14 is discharged to the rotating plate 13 in a linear or water droplet state. Further, the water discharged to the rotating plate 13 becomes finer water droplets because the moment of the force applied to the water generated by the rotation of the rotating plate 13 is larger than the frictional force with the rotating plate 13. Is discharged from the rotating plate 13 in the centrifugal direction. The released water droplets collide with the collision wall 8 (not shown in FIG. 2), so that the water droplets are further destroyed and finely divided water droplets can be obtained.

Further, as illustrated in FIG. 2, by making the width B of the opening 14 larger than the width A of the spiral groove 15, the water induced by the spiral groove 15 is in the vicinity of the opening 14. It is possible to suppress the accumulation of water in the pump, reduce the passage resistance of water passing through the opening 14, and efficiently discharge water droplets from the opening 14 of the pumping pipe 9.

Instead of the spiral groove 15, a spiral-shaped projecting piece 17 as shown in FIG. 3 may be provided. Even in this case, the effect of pumping water by the spiral structure can be obtained, and the effect of inducing water to the opening 14 can also be obtained. In this case, by making the width of the opening 14 larger than the width of the spiral-shaped projecting piece 17, water droplets can be efficiently discharged from the opening 14 of the pumping pipe 9. That is, when the spiral-shaped projecting piece 17 is used, the width C of the spiral-shaped projecting piece 17 can be appropriately designed to have a required width regardless of the width B of the opening 14.

Although the number of rotating plates 13 is shown as two in FIG. 1, the number of rotating plates 13 can be changed according to the target performance, and the number of rotating plates 13 may be increased or decreased as appropriate according to the dimensions of the pumping pipe 9.

The spiral grooves 15 or the spiral protrusions 17 do not have to be at equal intervals. For example, in the vertical direction of the pumping pipe 9, the lower part close to the water storage portion 10 is set to a finer interval, and the closer to the upper part. The spacing between the spirals may be widened. In that case, the length of the pumping pipe 9 immersed in the water storage unit 10 can be shortened, which is more preferable.

The liquid to be crushed may be other than water, and can be applied to, for example, a liquid such as hypochlorous acid water having bactericidal properties. Further, in the case of a liquid having a viscosity higher than that of water such as hypochlorous acid water, it was more difficult to pump water than water in the conventional configuration, but by using the configuration of the present invention, the liquid having a high viscosity is opened 14 It can be made possible to easily release from.

The liquid micronization device of the present invention is a method of sucking water from the water storage part by rotating a pumping pipe whose lower part is immersed in the water storage part, and by providing a spiral groove inside the water storage part, The pumping efficiency of the pumping pipe can be improved. As a result, the centrifugal force required to suck up water can be reduced, so that the diameter of the pumping pipe can be reduced, and a compact liquid miniaturization device can be provided. Is.

Therefore, for example, in addition to air purifiers and air conditioners, it is expected to be used in humidifying devices and sauna devices. In addition, since the required centrifugal force can be suppressed, it can also be used for micronizing equipment for highly viscous liquids that require a greater centrifugal force than water, for example, other liquids such as hypochlorous acid water and oil emulsions. It is possible to do.
