Below the collision wall 8, a cylindrical eliminator 17 is arranged so as to separate the inside and outside of the liquid atomization chamber 7, and collects some of the atomized water droplets. This eliminator 17 is fixed so as to be included in an eliminator holder 19 connected to the lower portion of the collision wall 8 . Specifically, the eliminator holder 19 includes a first holding portion 19a extending vertically downward from the top plate 19c and a second holding portion 19b extending vertically downward from the top plate 19c inside the first holding portion 19a. and The eliminator 17 is clamped and fixed between the first holding portion 19a and the second holding portion 19b of the eliminator holder 19 (see FIG. 4, which will be described later). A supporting portion 22 of a water flow control plate 20, which will be described later, is connected to the second holding portion 19b of the eliminator holder 19. As shown in FIG.

The eliminator 17 is arranged in the air passage 5 and collects droplets of the water contained in the air atomized in the liquid atomization chamber 7 . As a result, the air flowing through the air passage 5 contains only vaporized water.

A water flow control plate 20 is provided above the water storage section 14 so as to cover the water storage section 14 . Specifically, the water flow control plate 20 has an outer diameter smaller than the inner wall diameter of the water reservoir 14, and is provided below the space surrounded by the eliminator 17 so as to cover the upper part of the water reservoir 14. there is That is, the water flow control plate 20 is provided so that a predetermined gap 27 is formed between the inner wall surface 26 of the water reservoir 14 and the outer edge 24 of the water flow control plate 20 (see FIG. 5 described later).

The water flow control plate 20 will be described with reference to FIGS. 3 and 4. FIG. FIG. 3 is a schematic perspective view of the water flow control plate 20 of the liquid atomization device 1 as viewed obliquely from above. FIG. 4 is a schematic perspective view of the water flow control plate 20 of the liquid atomization device 1 as viewed obliquely from below. In addition, in FIG. 3, the eliminator holder 19 etc. which comprise the liquid atomization apparatus 1 are taken as the horizontal cross section.

As shown in FIG. 3, the water flow control plate 20 has a substantially disk shape, and a first opening 21 having a diameter that allows the pumping pipe 9 to pass through the water flow control plate 20 is formed in the center. . The water flow control plate 20 is formed with a gently sloping surface that descends from the outer peripheral portion toward the first opening 21 (see FIG. 5, which will be described later). The gently sloping surface is formed at an angle of about 5 degrees or less (3 degrees in the first embodiment) with respect to the horizontal plane. The water flow control plate 20 has a plurality of support portions 22 on the upper surface side of the outer peripheral portion (outer edge 24 ), and is fixed to the second holding portion 19 b of the eliminator holder 19 via the support portions 22 . Here, the water flow control plate 20 is immersed in the water stored in the water storage portion 14 by water supply, that is, when the water storage portion 14 is full, the water level at the first opening 21 of the water flow control plate 20 is It is arranged at a position reaching the upper surface side of the neighborhood.

As shown in FIG. 4 , the water flow control plate 20 is provided with a projecting portion 23 projecting downward in the vertical direction in a cylindrical shape so as to surround the first opening 21 on the lower surface side. The projecting portion 23 is formed by projecting two cylindrical shapes having different diameters.

As shown in FIGS. 3 and 4, the liquid atomization device 1 has a second opening 25 composed of the outer edge 24 of the water flow control plate 20, the eliminator 17, and the second holding portion 19b of the eliminator holder 19. is formed. Although the details will be described later, through this second opening 25, the water that has been lifted to the upper surface side of the water flow control plate 20 along the outer wall of the water flow control plate 20 due to the rotation of the water flow pipe 9 flows from the outer edge 24 of the water flow control plate 20. It is discharged to the outer peripheral side of the water flow control plate 20 (radial direction of the water flow control plate 20).

Next, the operating principle of water atomization in the liquid atomization device 1 will be described. When the rotary shaft 10 is rotated by the rotary motor 11 and the pumping pipe 9 is rotated accordingly, the water stored in the water reservoir 14 is pumped up by the pumping pipe 9 due to the centrifugal force generated by the rotation. The rotation speed of the pumping pipe 9 is set between 1000 and 5000 rpm. Since the pumping pipe 9 has an inverted conical hollow structure, the water pumped up by the rotation is pumped up along the inner wall of the pumping pipe 9 . Then, the pumped water is discharged in the centrifugal direction from the opening 13 of the pumping pipe 9 along the rotary plate 12 and scatters as water droplets.

The water droplets scattered from the rotating plate 12 fly in the space surrounded by the collision wall 8, collide with the collision wall 8, and become finer. On the other hand, the air passing through the liquid atomization chamber 7 moves from above the collision wall 8 into the interior of the collision wall 8, and moves from below to the outside of the collision wall 8 while containing water droplets crushed (miniaturized) by the collision wall 8. do. As a result, the air sucked from the suction port 2 of the liquid atomization device 1 can be humidified, and the humidified air can be blown out from the blowout port 3 .

The liquid to be atomized may be other than water, and may be, for example, hypochlorous acid water having sterilizing/deodorizing properties. The air sucked from the suction port 2 of the liquid atomization device 1 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 1 is placed. Sterilization/deodorization can be performed.

Here, when the pumping pipe 9 rotates, the water in the water storage part 14 is also in contact with the outer wall surface of the pumping pipe 9 , and is pumped upward along the outer wall surface of the pumping pipe 9 .

In the conventional liquid atomization device 101 shown in FIGS. 7 and 8, the water that is lifted up to the upper surface of the water flow blocking means 111 along the outer peripheral side of the pumping pipe 109 while creating a rotating water flow as the pumping pipe 109 rotates is Part of it collides with the support piece 113 to create a return water flow 115 that flows toward the center of the water flow blocking means 111 . This return water flow 115 collides with the water lifted to the upper surface of the water flow blockage means 111 by the above-mentioned pumping pipe 109, creates a complicated turbulent water flow, entrains air into the water, and generates bubbles, which burst. It was to generate a loud buzzing noise at times.

However, in the liquid atomization device 1 according to Embodiment 1, the disk-shaped water flow control plate 20 covering the upper part of the water storage part 14 is provided on the upper surface thereof from the outer edge 24 of the water flow control plate 20 to the first opening 21 . A water flow control plate 20 having an inclination of a predetermined angle is provided. It is configured so that it can be released to the side. This prevents an increase in noise due to the generation of air bubbles accompanying the rotation of the pumping pipe 9 . The details will be described below.

FIG. 5 is a schematic cross-sectional view showing the action of the water flow control plate 20 of the liquid atomization device 1. As shown in FIG. A solid line 41 in FIG. 5 indicates the water level in this state, and an arrow 42 indicates the direction of water flow in the water reservoir 14 .

As shown in FIG. 5 , the rotation of the pumping pipe 9 causes the water in the reservoir 14 to pass through the first opening 21 in the water flow control plate 20 and be lifted to the upper surface of the water flow control plate 20 . The water lifted to the upper surface side of the water flow control plate 20 moves in the outer peripheral direction due to centrifugal force and reaches the outer edge 24 of the water flow control plate 20 . The water reaching the outer edge 24 passes through the second opening 25 and is discharged from the water flow control plate 20 (the outer edge 24 of the water flow control plate 20). The water flow control plate 20 has a gently inclined surface that descends from the outer peripheral portion of the outer edge 24 toward the first opening 21, but since the inclination angle is 5 degrees or less, it is lifted to the upper surface side. The water moves in the outer peripheral direction as it is with the force of the pumping. The inclined surface of the water flow control plate 20 may be configured so as to gently descend from the first opening 21 toward the outer edge 24 .

Since a gap 27 is provided in the radial direction of the water flow control plate 20 between the outer edge 24 of the water flow control plate 20 and the inner wall surface 26 of the water reservoir 14, the discharged water passes through this gap 27. It moves to the water storage part 14 and moves to the bottom side of the water storage part 14 as it is. The water then passes under the water flow control plate 20 and returns to the pumping pipe 9 . In this way, the water adhered to the outer wall surface of the pumping pipe 9 and lifted up is the first opening 21, the upper surface of the water flow control plate 20, the second opening 25, the gap 27, the bottom of the water flow control plate 20, the water lifting pipe 9, to form a unidirectional flow. Since a route that circulates in this order is created, a stable water flow can be created without generating turbulent water flow. As a result, the effect of preventing noise generation can be enhanced.

As described above, according to the liquid atomization device 1 according to Embodiment 1 of the present invention, the water flow created by the water lifted up along the outer peripheral side of the pumping pipe 9 due to the rotation of the pumping pipe 9 is formed into a disc shape. can be made only in one direction toward the outer peripheral side of the water flow control plate 20, and it is possible to suppress the generation of air bubbles without generating a complicated turbulent water flow due to the collision of water, so that the outer peripheral side of the pumping pipe 9 It is possible to prevent the generation of noise caused by the water flow generated in the

In addition, since the water flow control plate 20 is arranged at a position where the first opening 21 is submerged in the water stored in the water storage portion 14 when the water storage portion 14 is full of water, the water flow control plate 20 can be Since there is no air pool on the lower surface side of the water flow control plate 20 around the 1 opening 21, collision of water with the lower surface side of the water flow control plate 20 caused by the rotation of the pumping pipe 9 is suppressed. Thereby, generation of noise can be further reduced.

In addition, as shown in FIG. 5, the top surface of the water flow control plate 20 is configured to have an inclined surface that descends at a predetermined angle from the outer peripheral side (outer edge 24) toward the first opening 21. When the rotation of the pipe is stopped, the water remaining on the upper surface of the water flow control plate 20 can be quickly returned to the water reservoir 14.例文帳に追加Therefore, it is possible to prevent the upper surface of the water flow control plate 20 from becoming dirty due to the drying of the remaining water, prevent the water flow from being disturbed by the dirt, and prevent the noise from being caused by the disturbed water flow.

In addition, as shown in FIG. 5, a cylindrical protrusion 23 surrounding the first opening 21 is provided on the lower surface of the water flow control plate 20, thereby reducing the friction between the water flowing in the reservoir 14 and the water flow control plate 20. increases, making it difficult for the water in the water reservoir 14 to flow, thereby increasing the resistance to the rotational flow that occurs on the outer circumference of the pumping pipe 9 as the pumping pipe 9 rotates. For this reason, it is possible to suppress a decrease in the amount of pumped water that accompanies an increase in the rotation speed of the pumping pipe 9 .

Next, a heat exchange device equipped with the liquid atomization device according to Embodiment 1 will be described with reference to FIG. FIG. 6 is a schematic perspective view of a heat exchange gas apparatus 60 equipped with a liquid atomization apparatus according to the first embodiment.

The liquid atomization device 50 corresponds to the liquid atomization device 1 according to the first embodiment.

The indoor air intake port 61 sucks indoor air, and the sucked air is discharged to the outside through an exhaust port 62. - 特許庁Also, the outdoor air intake port 63 sucks in outdoor air, and the sucked outdoor air is supplied from the air supply port 64 into the room. At this time, heat exchange is performed by the heat exchange element 65 between the air sent from the indoor air intake port 61 to the air outlet 62 and the outside air sent from the outside air intake port 63 to the air supply port 64 .

As one of the functions of the heat exchange air device, there is a device incorporating a liquid vaporization device such as a moisture vaporization device for humidification and a hypochlorous acid vaporization device for sterilization/deodorization. The heat exchange gas device 60 incorporates the liquid atomization device 50 as a device for vaporizing the liquid. Specifically, the liquid atomization device 50 is provided via a connection duct 66 on the air supply port 64 side of the heat exchange device 60 . Water is supplied to and drained from the liquid atomization device 50 by a water supply/drainage pipe 51 .

The heat exchange air device 60 equipped with the liquid atomization device 50 applies water or hypochlorous acid atomized by the liquid atomization device 50 to the outside air heat-exchanged by the heat exchange element 65, The air is supplied into the room from the air supply port 64 . By using the liquid atomization device 50 as a mechanism for vaporizing these liquids, it is possible to obtain a heat exchange gas device 60 that is smaller and more energy efficient.

In addition, while recovering the moisture discharged to the outside during ventilation into the air supplied to the room, if the moisture cannot be completely recovered by the heat exchange element 65 (corresponding to the humidity recovery unit), the liquid is atomized. The room can be humidified and maintained within a comfortable humidity range as it can be supplemented or overfilled as it passes through the device 50 .

Here, instead of the heat exchange device 60, the liquid atomization device 50 may be provided in an air cleaner or an air conditioner. As one of the functions of air purifiers or air conditioners, there is a device incorporating a device for vaporizing liquid such as a moisture vaporization device for humidification or a hypochlorous acid vaporization device for sterilization/deodorization.
