Air containing water atomized by the liquid atomization chamber 5 is blown from the liquid atomization chamber 5 to the space 24 by the air passage 16, and sent to the outlet 3 by the air passage 17 through the space 24. .

Inside the liquid atomization chamber 5 surrounded by the collision wall 12 , a cylindrical water pumping pipe 11 that pumps up water while rotating is provided.

The number of rotating plates 14 is appropriately set according to the target performance and the dimensions of the pumping pipe 11 .

In addition, the wall surface of the pumping pipe 11 is provided with an opening 13 penetrating through the wall surface of the pumping pipe 11 .

A diameter, more preferably a diameter corresponding to 5% to 20% of the pumping pipe 11 can be mentioned. In addition, the dimensions of each opening 13 may be the same within the above range.

A water storage part 4 for storing water pumped by the water pumping pipe 11 is provided below the liquid atomization chamber 5 in the vertical direction below the water pumping pipe 11 . The reservoir 4 has a depth such that a portion of the lower portion of the pumping pipe 11, for example, a length of about one-third to one-hundredth of the height of the cone of the pumping pipe 11 is submerged. This depth can be designed according to the required pumping capacity.

A water supply unit 7 supplies water to the water storage unit 4 . A water supply pipe (not shown) is connected to the water supply unit 7, and water is supplied directly from the water supply pipe through a water pressure regulating valve, for example. The water supply unit 7 may be configured to draw up only the necessary amount of water from a water tank provided outside the liquid atomization chamber 5 in advance by the siphon principle and supply water to the water storage unit 4 . The water supply portion 7 is provided vertically above the bottom surface of the water storage portion 4 . The water supply unit 7 is preferably provided vertically above not only the bottom surface of the water storage unit 4 but also the top surface of the water storage unit 4 (the maximum water level that can be stored in the water storage unit 4).

The liquid atomization chamber 5 is provided with a water level detection section 8 for detecting the water level of the water storage section 4 . The water level detector 8 has a float switch 20 . The float switch 20 is turned off when the water level of the reservoir 4 has not reached a certain level, and turned on when the water level of the water reservoir 4 has reached a certain level. This constant water level is set so that the lower part of the pumping pipe 11 is submerged in the water stored in the water storage part 4 . When the float switch 20 is off, water is supplied from the water supply unit 7 to the water storage unit 4, and when the float switch 20 is on, the supply of water from the water supply unit 7 to the water storage unit 4 is stopped. The water in the water reservoir 4 can be kept at a constant water level. The water level detection unit 8 is provided above the bottom surface of the water storage unit 4 in the vertical direction.

A drain pipe 18 is connected to the bottom surface of the water reservoir 4 . The drain port of the water reservoir 4 provided at the position where the drain pipe 18 is connected is provided at the lowest position of the water reservoir 4 . When the water atomization operation is stopped, the water stored in the water reservoir 4 is drained from the drain pipe 18 by opening a valve (not shown) provided in the drain pipe 18 .

The liquid atomization chamber 5 has an eliminator 19 below the impingement wall 12 . Specifically, an opening (not shown) provided in the middle of the air passage 16 and below the collision wall 12 leading from the liquid atomization chamber 5 to the space 24 formed on the outer circumference of the inner cylinder 6. An eliminator 19 is provided to cover the . The eliminator 19 passes the water-containing air atomized in the liquid atomizing chamber 5 and collects water droplets from the water contained in the air.

Above the eliminator 19 , a protruding portion 21 that protrudes from the collision wall 12 toward the inside of the liquid atomization chamber 5 and covers the upper side of the eliminator 19 is provided. The projecting portion 21 is inclined downward toward the inside of the liquid atomization chamber 5 .

Further, in the body case 1, on the downstream side of the eliminator 19, a wall surface 16a (hereinafter referred to as "body case side wall surface 16a") of the air passage 16 provided on the inner wall of the body case 1 is partially curved. A guide portion 22 is provided. Here, as shown in FIG. 3A, the upper end 22a of the guide portion 22 is provided at a position higher than the upper end 19a of the eliminator 19. As shown in FIG.

Further, as shown in FIG. 1 , a bottom portion 23 is provided that is in contact with the lower end of the guide portion 22 and that is inclined downward toward the water storage portion 4 . The projecting portion 21 and the bottom portion 23 are provided so as to be substantially parallel. By providing the projecting portion 21 and the bottom portion 23 so as to be substantially parallel, the air flow in the eliminator 19 can be made substantially uniform. The projecting portion 21 and the bottom portion 23 do not have to be completely parallel.

Here, the operating principle of water atomization in the liquid atomization device 50 will be described. When the rotating shaft 10 is rotated by the rotary motor 9 and the pumping pipe 11 is rotated accordingly, the water stored in the water storage unit 4 is pumped up from the pumping port of the pumping pipe 11 by the centrifugal force generated by the rotation. The rotation speed of the pumping pipe 11 is set between 1000 and 5000 rpm. Since the pumping pipe 11 has an inverted conical hollow structure, the water pumped up by the rotation is pumped up along the inner wall of the pumping pipe 11 . Then, the pumped water is discharged in the centrifugal direction through the opening 13 of the pumping pipe 11 along the rotating plate 14 and scatters as water droplets.

The water droplets scattered from the rotating plate 14 fly in the space surrounded by the collision walls 12, collide with the collision walls 12, and become finer. On the other hand, the air passing through the liquid atomization chamber 5 moves into the inner cylinder 6 from the upper opening of the inner cylinder 6 . The air, including water crushed (miniaturized) by the collision wall 12 , passes through the eliminator 19 through the air path 16 to an opening (not shown) provided below the collision wall 12 . to the space 24 outside the inner cylinder 6 . The air that has moved to the space 24 is blown out from the outlet 3 through the air passage 17 . As a result, the air sucked from the suction port 2 of the liquid atomization device 50 can be humidified, and the humidified air can be blown out from the blowout port 3 .

In addition, by changing the amount of water pumped up by the pumping pipe 11 according to the amount of rotation of the pumping pipe 11, and by changing the amount of water droplets scattered from the rotating plate 14 of the pumping pipe 11, the droplets are made finer by the collision wall 12. You can vary the amount of water. Therefore, the amount of water contained in the air sucked from the suction port 2 of the liquid atomization device 50 can be changed by the amount of rotation of the pumping pipe 11 . That is, the liquid atomization device 50 can control the amount of humidification by the amount of rotation of the pumping tube 11 .

In addition, the eliminator 19 collects droplets of the water that has been atomized in the liquid atomizing chamber 5 and included in the air. Can contain only fresh water. As a result, the liquid atomization device 50 can prevent water droplets from adhering to the outlet 3 .

Since the kinetic energy of the water scattered from the rotor plate 14 is attenuated by friction with the air inside the collision wall 12, it is preferable to bring the rotor plate 14 as close to the collision wall 12 as possible. On the other hand, the closer the impingement wall 12 and the rotor plate 14 are, the less the amount of air passing through the interior of the impingement wall 12 is.

Moreover, the liquid to be atomized may be other than water, and may be, for example, a liquid such as hypochlorous acid water having sterilization/deodorant properties. The air sucked from the suction port 2 of the liquid atomization device 50 contains the atomized hypochlorous acid water, and the air is blown out from the blowout port 3, so that the space in which the liquid atomization device 50 is placed. Sterilization/deodorization can be performed.

Next, with reference to FIG. 3, the effect of providing the projecting portion 21 above the eliminator 19 and providing the guide portion 22 downstream of the eliminator 19 will be described.

FIG. 3A is a schematic diagram schematically showing the flow of air through the air passage 16 and the flow of water droplets 30 scattered from the downstream side surface of the eliminator 19 when the projecting portion 21 and the guide portion 22 are provided. is. FIG. 3B schematically shows the flow of air through the air passage 16 and the flow of water droplets 30 scattered from the downstream side surface of the eliminator 19 when neither the projecting portion 21 nor the guide portion 22 is provided. It is a schematic diagram. FIG. 3C schematically shows the flow of air through the air passage 16 and the flow of water droplets 30 scattered from the downstream side surface of the eliminator 19 when the guide portion 22 is provided and the projecting portion 21 is not provided. It is a schematic diagram shown.

Most of the water droplets collected by the eliminator 19 fall inside the eliminator 19 due to their weight and are guided to the water reservoir 4 through the bottom portion 23 . However, as shown in FIGS. 3A to 3C, some of the water droplets 30 collected by the eliminator 19 are scattered from the downstream side surface (peripheral surface) of the eliminator 19 by the wind pressure of the air passing through the eliminator 19. do. The water droplets 30 scattered from the eliminator 19 are dispersed in the main body case provided downstream of the eliminator 19 and on the outer peripheral side of the eliminator 19 (in the blowing direction of the air passage 16 blown from the eliminator 19 when viewed from the eliminator 19). It adheres to the main body case side wall surface 16a of the air passage 16 formed in the inner wall of 1. As shown in FIG.

The liquid atomization device 50 is not provided with the guide portion 22, and as shown in FIG. When a corner is formed with the bottom portion 23 , water droplets 30 adhering to the body case side wall surface 16 a of the air passage 16 tend to collect at the corner formed by the body case side wall surface 16 a and the bottom portion 23 .

Also, the air flow is formed along the shortest path. As a result, when the liquid atomization device 50 is not provided with the projecting portion 21, as shown in FIG. The main stream of the air passage 16 is formed so as to flow into the space 24 through the vicinity of the lower end.

As described above, when neither the guide portion 22 nor the projecting portion 21 is provided in the liquid atomization device 50, the water droplets adhering to the main body case side wall surface 16a of the air passage 16, which is away from the vicinity of the lower end of the collision wall 12, The water droplets 30 and the water droplets 30 collected at the corner formed by the side wall surface 16 a of the main body case and the bottom portion 23 are unlikely to come into contact with the main flow of the air passage 16 .

Further, in this case, in the air passage 16, the direction of the air flowing vertically downward inside the collision wall 12 is reversed near the lower end of the collision wall 12, and a space formed outside the collision wall 12 is formed. 24 flows vertically upward. That is, in the air passage 16, the direction of airflow is reversed in a narrow region near the lower end of the collision wall 12, and the direction of airflow is not reversed in a sufficiently wide region, resulting in large pressure loss. Along with the pressure loss, the air deviated from the main stream of the air passage 16 stays on the side wall surface 16 a of the main body case of the air passage 16 and near the corner formed by the side wall surface 16 a of the main body case and the bottom portion 23 .

Therefore, even after the operation of the liquid atomization device 50 is finished, there is a high possibility that these water droplets 30 remain inside the liquid atomization device 50 without being dried, and bacteria and mold are likely to occur.

On the other hand, when the liquid atomization device 50 is provided with the guide portion 22, as shown in FIGS. , the main body case side wall surface 16a formed in the guide portion 22 is curved to flow to the bottom portion 23, and the inclination of the bottom portion 23 makes it easier to be guided to the water storage portion 4 as it is. That is, the existence of the guide portion 22 makes it difficult for the water droplets 30 to stay on the side wall surface 16a of the main body case. However, part of the water droplets 30 adhering to the main case side wall surface 16a remains on the main case side wall surface 16a due to the surface tension of the main case side wall surface 16a, and the main case side wall surface 16a remains wet.

Here, when the liquid atomization device 50 is provided with the guide portion 22 and the liquid atomization device 50 is not provided with the projection portion 21, as shown in FIG. Similarly, the main stream of the air passage 16 is formed so that the air containing the liquid atomized by the liquid atomization chamber 5 flows through the vicinity of the lower end of the collision wall 12 and into the space 24 . That is, in this case, of the main body case side wall 16a of the air duct 16 that is curved in the guide portion 22, the main body case side wall 16a that is away from the vicinity of the lower end of the collision wall 12 is provided with the air duct 16. Hard to reach the mainstream. Therefore, in this case also, after the operation of the liquid atomization device 50 is finished, the water droplets 30 remaining attached to the side wall surface 16a of the main body case are difficult to dry, and bacteria and mold are likely to occur.

On the other hand, if the protrusion 21 is provided in the liquid atomization device 50, as shown in FIG. The main stream of the air passage 16 is formed so as to bend inwardly of the heating chamber 5 . Then, at the inward tip of the liquid atomization chamber 5 of the protrusion 21 (the tip of the protrusion 21 ), the air flow bent inward of the liquid atomization chamber 5 is bent again, and flows downstream of the eliminator 19 . The main stream of the air passage 16 is formed so as to flow toward it. After passing through the eliminator 19 , the air flows upward through the space 24 formed outside the collision wall 12 , forming the main stream of the air passage 16 .

As described above, when the protruding portion 21 and the guide portion 22 are provided in the liquid atomizing device 50 , the presence of the guide portion 22 causes water droplets 30 scattered from the eliminator 19 to adhere to the side wall surface 16 a of the main body case of the air passage 16 . can be made difficult to remain on the side wall surface 16a of the main body case.

On the other hand, as described above, the air passing downward inside the collision wall 12 is bent by the protrusion 21 toward the inside of the liquid atomization chamber 5, and then flows downstream of the eliminator 19 at the tip of the protrusion 21. After passing through the eliminator 19 , it flows upward through the space 24 formed outside the impingement wall 12 .

In this way, the air passing vertically downward inside the collision wall 12 is reversed in direction by the air passage 16 formed in a large circle, and flows vertically upward through the space 24 formed outside the collision wall 12. flow toward As a result, the pressure loss of the air flowing through the air passage 16 can be reduced, so that the air passing through the eliminator 19 can be flowed over the entire eliminator 19 at a uniform wind speed. Therefore, the air that has passed through the eliminator 19 can flow along the main body case side wall surface 16a of the air passage 16 of the guide portion 22 that is curved. The side wall surface 16a can be easily dried. Therefore, the liquid atomization device 50 according to the present embodiment can shorten the internal drying time after the end of operation, and can suppress the generation of bacteria and mold.

In addition, compared to the case where the air flows concentratedly in a partial area of the eliminator 19 due to the absence of the projecting portion 21, the wind speed of the air flowing through the eliminator 19 can be suppressed, so that the air scatters from the downstream side surface of the eliminator 19. It is possible to reduce the amount of water droplets 30 per se. Therefore, the liquid atomization device 50 according to the present embodiment can shorten the internal drying time after the end of the operation also from this aspect. Moreover, since the water droplets can be collected by the entire eliminator 19, there is an effect that the water droplet collection effect can be enhanced.

Further, since the projecting portion 21 provided above the eliminator 19 and the bottom portion 23 provided below the eliminator 19 are provided substantially parallel, the air flow in the eliminator 19 can be made substantially uniform. can. As a result, the air blown out from the eliminator 19 can be reliably brought into contact with the body case side wall surface 16a of the air passage 16 of the guide portion 22, and the body case side wall surface 16a can be reliably dried. Further, by making the air flow in the eliminator 19 substantially uniform, it is possible to suppress the increase in air velocity at a specific position inside the eliminator 19 . As a result, the speed of the air increases at a specific position inside the eliminator 19, and scattering of water droplets 30 therefrom can be suppressed.

In addition, since the projecting portion 21 provided above the eliminator 19 is inclined downward toward the inside of the liquid atomization chamber 5 , the projection 21 is inclined downward from the upper side of the inner cylinder 6 of the liquid atomization chamber 5 . The flowing air can be bent inward in the liquid atomization chamber 5 while suppressing pressure loss.

When the impingement wall 12 crushes the water flying from the rotating plate 14 of the pumping pipe 11, part of the water adheres to the impingement wall 12 and falls below the impingement wall 12 due to its weight. The dropped water droplets 30 are received by the projecting portion 21 and guided to the water storage portion 4 by the inclination of the projecting portion 21 . Since the protruding portion 21 is provided above the eliminator 19 , it is possible to suppress the water droplets adhering to the collision wall 12 and falling onto the eliminator 19 . Therefore, the existence of the projecting portion 21 prevents the eliminator 19 from being excessively wet with water droplets falling from the collision wall 12 , and as a result, it is possible to prevent many water droplets 30 from scattering from the eliminator 19 . Therefore, from this aspect as well, the internal drying time after the end of the operation can be shortened.

Further, in the liquid atomization device 50 according to the present embodiment, the upper end 22a of the guide portion 22 is provided at a position higher than the upper end 19a of the eliminator 19, as shown in FIG. 3(a). Here, some of the water droplets 30 that scatter from the downstream side surface of the eliminator 19 scatter upward along the flow of air that flows inside the eliminator 19 . In particular, in the liquid atomization device 50 according to the present embodiment, the air passing through the eliminator 19 circulates widely due to the protrusion 21 and flows along the guide portion 22, so that the water droplets 30 scattered from the downstream side surface of the eliminator 19 are scattered upward. more likely to scatter toward

On the other hand, in the liquid atomization device 50 according to the present embodiment, the upper end 22a of the guide portion 22 is provided at a position higher than the upper end 19a of the eliminator 19. Including the scattered water droplets 30, it is possible to make it easier to adhere to the side wall surface 16a of the main body case formed curvedly on the guide portion 22. As shown in FIG. Therefore, water droplets 30, including water droplets 30 scattered upward from the upper portion of the downstream side surface of the eliminator 19, adhering to the main body case side wall surface 16a formed in the guide portion 22 are removed by the curvature of the main body case side wall surface 16a. It can flow to the bottom 23 and be guided via the bottom 23 to the water reservoir 4 . Therefore, the internal drying time after the end of the operation can be further shortened.

In addition, the upper end 22a of the guide portion 22 may be provided so as to have substantially the same height as the upper end 19a of the eliminator 19 . Here, "substantially the same height" means that the upper end 22a of the guide portion 22 and the upper end 19a of the eliminator 19 are substantially at the same height. For example, with the upper end of the water storage portion 4 as a reference, the height from the upper end of the water storage portion 4 to the upper end 22a of the guide portion 22 is within ±5% of the height from the upper end of the water storage portion 4 to the upper end 19a of the eliminator 19. In this case, it can be considered that the upper end 22a of the guide portion 22 and the upper end 19a of the eliminator 19 are approximately the same height.

When the upper end 22a of the guide portion 22 is provided to be approximately the same height as the upper end 19a of the eliminator 19, part of the water droplets 30 scattered upward from the upper portion of the downstream side surface of the eliminator 19 adheres to the guide portion 22. Although there is a possibility that it may not be possible, since there is no curvature of the main body case side wall surface 16a in the guide portion 22 at a position higher than the upper end 19a of the eliminator 19, the cross-sectional width of the space 24 can be kept constant. Therefore, pressure loss in the space 24 can be suppressed.
