Liquid miniaturization device

Abstract

A liquid atomizing device (1) that contains atomized water in the air drawn in from the inlet (2) and blows it out from the outlet (3) comprises: a cylindrical water-lifting pipe (9) that discharges water lifted from the water-lifting outlet (9a) in a centrifugal direction; a water storage section (14) that stores the lifted water; a drain outlet (16a) that discharges water from the bottom surface of the water storage section (14); and a humidification control section (30) that controls the atomization operation of the water. During the atomization operation, the water-lifting pipe (9) rotates at a second rotational speed, causing the water in the water storage section (14) inside the water-lifting pipe (9) to generate a vortex. A gap connecting the water-lifting outlet (9a) and the drain outlet (16a) is formed at the center of the vortex, blocking the water in the water storage section (14). When the humidification control section (30) determines that the humidity of the air drawn in from the inlet (2) exceeds the target humidity, it rotates the water-lifting pipe (9) at a fourth rotational speed.

Description

[0001] This application is a divisional application of the invention patent application with application number 202080024159.0, application date March 30, 2020, and invention title "Liquid Micronization Device". Technical Field

[0002] The present invention relates to a liquid micronization device that micronizes a liquid, contains the micronized liquid in inhaled air, and blows it out. Background Technology

[0003] Conventional liquid micronization devices exist that atomize water, infuse the inhaled air with the atomized water, and then blow it out (e.g., Patent Document 1). Such conventional liquid micronization devices include an air intake, an air outlet, and a liquid micronization chamber for atomizing water, located within an air passage between the intake and outlet. The liquid micronization chamber includes a water storage section and a water delivery pipe fixed to the rotating shaft of a rotary motor. The water delivery pipe, rotated by the rotary motor, atomizes the water stored in the water storage section, projecting the atomized water centrifugally. The projected water collides with a collision wall, thereby atomizing the water.

[0004] In addition, existing liquid micronization devices perform humidification operation while providing feedback control based on indoor humidity (the humidity of the intake air). Such liquid micronization devices perform humidification operation when the indoor humidity is lower than the target humidity, and stop humidification operation when the indoor humidity exceeds the target humidity.

[0008] Patent Document 2: Japanese Patent Application Publication No. 2009-279514 Summary of the Invention

[0009] Existing liquid humidification devices include a drain pipe (drain outlet) connected to a water storage unit for draining water stored in the storage unit. These devices create a gap between the drain pipe (drain outlet) and the water supply pipe (water supply outlet) by rotating the water supply pipe, thus preventing water from the storage unit from draining out. In other words, existing liquid humidification devices control drainage based on whether the water supply pipe rotates. Therefore, during humidification operation, if the humidity level repeatedly exceeds or falls below the target humidity level, the rotation of the water supply pipe is repeatedly executed and stopped, resulting in repeated water discharge and supply to the storage unit. In other words, in existing liquid humidification devices, there is concern about increased water consumption (drainage volume) when feedback control of humidification volume is implemented during humidification operation.

[0010] The present invention was made to solve the above-mentioned technical problems and provides a liquid micronization device that can reduce the amount of water (liquid) used when the humidification amount is controlled by feedback during humidification operation.

[0011] The liquid atomizing device of the present invention is a device that contains atomized liquid in air drawn in through an inlet and blown out through an outlet. The liquid atomizing device is characterized by comprising a liquid-lifting pipe, a collision wall, a storage section, and a control section. The liquid-lifting pipe is cylindrical and has a liquid-lifting port at its vertical lower position. As the rotating shaft rotates, the liquid drawn in through the liquid-lifting port is discharged centrifugally. The collision wall atomizes the liquid by colliding with the liquid discharged from the liquid-lifting pipe. The storage section is located at the vertical lower position of the liquid-lifting pipe and stores the liquid drawn in through the liquid-lifting port. The liquid is discharged from the bottom surface of the storage section through a discharge port. The control section controls the atomization operation of the liquid in the liquid atomizing device. The inlet is connected to an air supply device having a humidity recovery section. During the atomization operation, the liquid-lifting pipe rotates at any speed from a first rotational speed to a second rotational speed that is greater than the first rotational speed. Any rotational speed within the range from the first to the second rotational speed is such that, by rotating, the liquid in the storage compartment generates a vortex inside the dispensing pipe, forming a gap at the center of this vortex that connects the dispensing port and the drain port, thus preventing the liquid in the storage compartment from flowing into the drain port. Furthermore, if the control unit determines that the humidity of the air drawn in from the intake port exceeds the target humidity, it rotates the dispensing pipe at the first rotational speed.

[0012] According to the present invention, a liquid micronization device is provided that can reduce the amount of liquid used when the humidification amount is controlled in humidification operation. Attached Figure Description

[0080] The liquid atomizing device of the present invention is a device that contains atomized water in air drawn in through an inlet and blows it out through an outlet. The liquid atomizing device includes a liquid-lifting pipe, a collision wall, a storage section, and a control section. The liquid-lifting pipe is cylindrical and has a liquid-lifting port at its vertical lower position. As the rotating shaft rotates, the liquid drawn in through the liquid-lifting port is discharged centrifugally. The collision wall atomizes the liquid by colliding with the liquid discharged from the liquid-lifting pipe. The storage section is located at the vertical lower position of the liquid-lifting pipe and stores the liquid drawn in through the liquid-lifting port. The liquid is discharged from the bottom surface of the storage section through a discharge port. The control section controls the atomization operation of the liquid in the liquid atomizing device. The inlet is connected to an air supply device having a humidity recovery section. During the atomization operation, the liquid-lifting pipe rotates at any speed from a first rotational speed to a second rotational speed that is greater than the first rotational speed. Any rotational speed within the range from the first to the second rotational speed is such that, by rotating, a vortex is generated inside the dispensing port of the liquid in the storage section, and a gap connecting the dispensing port and the drain port is formed at the center of this vortex, ensuring that the liquid in the storage section does not flow into the drain port. Furthermore, if the control unit determines that the humidity of the air drawn in from the suction port exceeds the target humidity, it rotates the dispensing pipe at the first rotational speed.

[0081] Based on this structure, during humidification operation (liquid micronization, especially water micronization), the control unit rotates the liquid dispensing pipe at a first rotational speed even when it determines that the humidity of the air drawn in from the intake exceeds the target humidity, thus suppressing the discharge of liquid from the storage compartment. Therefore, even when the humidity repeatedly exceeds or falls below the target humidity, the control unit can prevent the discharge of liquid from the storage compartment, reducing the amount of liquid used. In other words, in the case of feedback control of the humidification amount during humidification operation, it can become a liquid micronization device that can reduce the amount of liquid used.

[0082] Furthermore, in the liquid micronization device of the present invention, when the humidity of the air drawn in from the inlet is insufficient to the target humidity, the control unit rotates the liquid dispensing pipe at a third rotational speed within the range of a first rotational speed to a second rotational speed. In this way, in the feedback control of the humidification amount, the control unit can humidify to the necessary amount towards the target humidity when the humidity of the air drawn in from the inlet is insufficient to the target humidity.

[0083] Furthermore, in the liquid micronization device of the present invention, the control unit determines whether the humidity of the air drawn in from the inlet exceeds the target humidity in each first period. In this way, when feedback control of the humidification amount is performed during humidification operation, the adjustment of the humidification amount is performed in each first period. Therefore, even if the humidity of the air drawn in from the inlet changes drastically due to some reason (e.g., bathroom use), the humidification amount can be effectively adjusted towards the target humidity.

[0084] Furthermore, in the liquid micronization device of the present invention, it is preferable that the control unit stops rotating the liquid dispensing pipe when it determines that the humidity of the air drawn in from the inlet exceeds the target humidity for a second period longer than the first period. In this way, humidification of the air drawn in from the inlet is stopped when the indoor air reaches the target humidity for a second period. That is, during the period from stopping humidification to resuming humidification, the amount of liquid consumed by humidification caused by the rotation at the first speed, corresponding to the liquid volume (humidification amount), can be reduced.

[0085] Furthermore, in the liquid micronization device of the present invention, it is preferable that the control unit stops rotating the liquid dispensing pipe when it determines that the humidity of the air drawn in from the intake port exceeds the target humidity, and when the humidity of the air drawn in from the intake port becomes a first humidity higher than the target humidity. In this way, the control unit can suppress excessive humidification of the air drawn in from the intake port, and thus can more appropriately control the humidity in the room.

[0086] Furthermore, in the liquid micronization device of the present invention, the air supply device is configured to allow air whose humidity has been recovered by the humidity recovery unit to flow into the intake port. In this way, since the air with recovered humidity flows into the liquid micronization device (intake port), the humidity in the room can be controlled more appropriately.

[0087] Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. It should be noted that the embodiments described below represent preferred examples of the present disclosure. Therefore, the numerical values, shapes, materials, constituent elements, arrangement positions of constituent elements, and connection methods shown in the following embodiments are examples and are not intended to limit the present disclosure. Therefore, in the constituent elements of the following embodiments, constituent elements not described in the independent technical solutions representing the highest-level concept of the present invention will be described as arbitrary constituent elements. Furthermore, in the accompanying drawings, substantially identical structures are labeled with the same reference numerals, and repeated descriptions are omitted or simplified.

[0088] (Implementation Method 1)

[0089] First, refer to Figure 1 , Figure 2 The general structure of the liquid micronization device 1 according to Embodiment 1 of the present invention will be described. Figure 1 This is a schematic perspective view of the liquid micronization device according to Embodiment 1 of the present invention. Figure 2 This is a schematic cross-sectional view showing the internal structure of the liquid micronization device according to Embodiment 1 of the present invention.

[0090] like Figure 1As shown, the liquid micronization device 1 includes an air intake 2 for drawing in air and an air outlet 3 for blowing out air drawn in from the air intake 2. The air intake 2 is located on the side of the liquid micronization device 1. The air outlet 3 is located on the top of the liquid micronization device 1.

[0091] like Figure 2 As shown, air passages 4 to 6 are formed within the liquid micronization device 1, extending from the inlet 2 to the outlet 3. Furthermore, the liquid micronization device 1 includes a liquid micronization chamber 7 disposed within the air passages 4 to 6, and the inlet 2, the liquid micronization chamber 7, and the outlet 3 are connected.

[0092] The liquid micronization chamber 7 is the main part of the liquid micronization device 1, where water micronization is performed. In the liquid micronization device 1, air drawn in from the intake port 2 is transported to the liquid micronization chamber 7 via the air passage 4. Furthermore, the liquid micronization device 1 is configured such that the air passing through the air passage 4 contains water micronized in the liquid micronization chamber 7, and the water-containing air is sequentially blown out through the air passage 5 and air passage 6, and then out through the outlet 3. Here, the air passage 5 is configured to change the direction of the water-containing air from flowing downwards in the vertical direction towards the liquid micronization chamber 7 to flowing upwards in the vertical direction around its periphery. The air passage 6 is configured to allow the air passing through the air passage 5 to flow directly upwards in the vertical direction and be blown out through the outlet 3.

[0093] A cylindrical impact wall 8 with openings at the top and bottom is provided in the liquid atomization chamber 7. The impact wall 8 is fixed inside the liquid atomization chamber 7. In addition, a cylindrical water delivery pipe 9 (liquid delivery pipe) is provided inside the liquid atomization chamber 7, which rotates and draws water (liquid delivery pipe) on the inner side surrounded by the impact wall 8. The water delivery pipe 9 has an inverted conical hollow structure and a circular water delivery port 9a (liquid delivery port) at the bottom. In addition, a rotating shaft 10 is fixed at the center of the inverted conical top surface of the water delivery pipe 9, which is arranged in the vertical direction. The rotating shaft 10 is connected to a rotary motor 11 provided on the outer surface of the liquid atomization chamber 7, and the rotational motion of the rotary motor 11 is transmitted to the water delivery pipe 9 through the rotating shaft 10, so that the water delivery pipe 9 rotates. It should be noted that the rotary motor 11 is configured to perform rotational motion according to the control signal from the humidification control unit 30 described later.

[0094] The water delivery pipe 9 has a plurality of rotating plates 12 on its inverted conical top surface, which protrude outward from the outer surface of the water delivery pipe 9. The plurality of rotating plates 12 are formed such that a predetermined interval is provided between adjacent rotating plates 12 along the axial direction of the rotation axis 10, and they protrude outward from the outer surface of the water delivery pipe 9. Since the rotating plates 12 rotate together with the water delivery pipe 9, a horizontal disc shape coaxial with the rotation axis 10 is preferred. It should be noted that the number of rotating plates 12 is appropriately set according to the target performance or the size of the water delivery pipe 9.

[0095] In addition, a plurality of openings 13 are provided in the wall of the water delivery pipe 9. Each of the plurality of openings 13 is provided at a position that connects the interior of the water delivery pipe 9 with the upper surface of the rotating plate 12, which is formed in such a way that it protrudes outward from the outer surface of the water delivery pipe 9.

[0096] In the lower part of the liquid micronization chamber 7, a water storage section 14 is provided below the vertical direction of the water delivery pipe 9 to store the water pumped from the delivery port 9a by the water delivery pipe 9. The depth of the water storage section 14 is designed to immerse a portion of the lower part of the water delivery pipe 9, for example, one-third to one-hundredth of the cone height of the water delivery pipe 9. This depth can be designed according to the required water delivery volume. In addition, the bottom surface of the water storage section 14 is formed into a mortar shape (bowl shape) that slopes downward toward the delivery port 9a (see reference). Figure 3 ).

[0097] Water is supplied to the water storage section 14 via the water supply section 15. A water supply pipe 15a is connected to the water supply section 15, for example, supplying water directly from a tap water pipe via a water pressure regulating valve (water supply valve: not shown). The water supply section 15 is located vertically above the bottom surface of the water storage section 14. Furthermore, the water supply section 15 is preferably located not only on the bottom surface of the water storage section 14, but also vertically above the upper surface of the water storage section 14 (the surface capable of storing water at its maximum level). It should be noted that the water supply section 15 may also be configured to pre-draw the required amount of water from a water tank located outside the liquid atomization chamber 7 using only the siphon principle and supply water to the water storage section 14.

[0098] Furthermore, a water level detection unit 18 is provided in the liquid micronization device 1 to detect the water level in the water storage section 14. The water level detection unit 18 has a float switch 18a. The float switch 18a is disconnected when the water in the water storage section 14 has not reached a certain water level (full water state), and connected when the water in the water storage section 14 reaches a certain water level (full water state). That is, the water level detection unit 18 detects whether the water in the water storage section 14 is at a certain water level (full water state) through the float switch 18a. Moreover, the water level detection unit 18 outputs information related to the connection or disconnection of the float switch 18a to the humidification control unit 30. In detail, the humidification control unit 30 controls the supply of water from the water supply section 15 to the water storage section 14 when the float switch 18a is disconnected and the disconnected state lasts for a predetermined time (first time T1), and controls the supply of water from the water supply section 15 to the water storage section 14 to stop when the float switch 18a is connected. Here, the first time T1 is set to the time during which the water in the water storage section 14 will not decrease to a level that cannot be stirred up due to humidification. In this embodiment, it is set to a certain time (e.g., 30 minutes).

[0099] A drain pipe 16 is connected to the bottom surface of the water storage section 14. A circular drain outlet 16a (liquid outlet) located at the connection point of the drain pipe 16 is positioned at the lowest point of the bottom surface of the mortar-shaped water storage section 14. Water blocking and drainage of the drain pipe 16 are achieved by rotating the water lifting pipe 9. That is, the drain pipe 16 and the water lifting pipe 9 constitute the water blocking mechanism and the water lifting mechanism of the water storage section 14. It should be noted that for detailed information on the water blocking mechanism and the drainage mechanism of the water storage section 14 constituted by the drain pipe 16 and the water lifting pipe 9, please refer to... Figure 3 To be described later.

[0100] Additionally, a cylindrical separator 17 is provided below the collision wall 8 (in the space between the collision wall 8 and the water storage section 14). This separator 17 is arranged to be separated from the inside and outside of the liquid atomization chamber 7 and captures a portion of the atomized water droplets. Furthermore, the separator 17 is constructed of a porous body that allows air to pass through. The separator 17 is fixed by being enclosed within a separator holder 19 connected to the lower part of the collision wall 8. Specifically, the separator holder 19 is configured to have: a top panel 19c, a first holding portion 19a extending vertically downward from the top panel 19c, and a second holding portion 19b extending vertically downward from the top panel 19c at a position closer to the first holding portion 19a (on the side of the water delivery pipe 9). The separator 17 is held and fixed by the first holding portion 19a and the second holding portion 19b of the separator holder 19. It should be noted that a support portion 22 of the water flow control plate 20 is connected to the second holding portion 19b of the separator holder 19.

[0101] Separator 17 is disposed within air passage 5. By circulating within separator 17, water droplets contained in water in the air passing through liquid micronization chamber 7 are captured. Thus, the air flowing in air passage 5 contains only vaporized water.

[0102] The water flow control plate 20 is disposed above the water storage section 14, covering it. Specifically, the water flow control plate 20 is formed with an outer diameter smaller than the inner wall diameter of the water storage section 14, and is disposed below the space surrounded by the separator 17, covering the top of the water storage section 14. The water flow control plate 20 is generally circular in shape, with an opening (not shown) in the center that allows the water delivery pipe 9 to pass through it. In addition, the water flow control plate 20 has multiple support portions 22 on the upper surface of its outer periphery (outer edge), and is fixed to the second holding portion 19b of the separator holder 19 via the support portions 22. It should be noted that the water flow control plate 20 prevents the generation of air bubbles in the water flow accompanying the rotation of the water delivery pipe 9, thus preventing noise increase.

[0103] Furthermore, a humidification control unit 30 is provided in the liquid micronization device 1. The humidification control unit 30 controls the humidification action (water micronization action) in the humidification process by controlling the operation of the liquid micronization device 1. In addition, the humidification control unit 30 controls the drainage action (first process) and the drainage action (second process). The drainage action (first process) drains the water in the water storage unit 14 when the number of water supplies to the water storage unit 14 during the humidification action reaches a predetermined number of times. The drainage action (second process) drains the water in the water storage unit when the humidification action has continued for a predetermined time (second time T2). Here, the second time T2 is a fixed time (e.g., 24 hours). Furthermore, the humidification control unit 30 controls the drying action in the drying process that occurs when the operation of the liquid micronization device 1 is stopped.

[0104] It should be noted that the liquid micronization device 1 may also be a control unit 60a that controls the heat exchange ventilation device 60 but does not have a humidification control unit 30 (see reference). Figure 5 The structure controls the humidification (water micronization), drainage (first and second treatments), and drying actions.

[0105] Next, refer to Figure 2 The operating principle of humidification (water miniaturization) in the liquid miniaturization device 1 is explained.

[0106] First, air supply from the outside is initiated (air is drawn in from the intake port 2). Then, with no water in the water storage section 14, the rotating shaft 10 is rotated at a first speed R1 (e.g., 2000 rpm) by the rotating motor 11, correspondingly rotating the water delivery pipe 9. Water is then supplied from the water supply section 15 to the water storage section 14. At this time, in the water storage section 14, the water supplied is drawn into the water storage section 14 by the centrifugal force generated by the rotation of the water delivery pipe 9, and the water supplied to the water storage section 14 is blocked from draining from the drain port 16a. As a result, the water supplied from the water supply section 15 is stored in the water storage section 14. After the water storage section 14 is full, the supply of water from the water supply section 15 to the water storage section 14 is stopped. It should be noted that the water blocking mechanism and the drainage mechanism will be described later.

[0107] Next, the rotating shaft 10 is rotated at a second speed R2 by the rotating motor 11. Correspondingly, the water delivery pipe 9 is rotated, and the centrifugal force generated by this rotation draws water stored in the water storage section 14 into the water delivery pipe 9. Here, the second speed R2 of the rotating motor 11 (water delivery pipe 9) is set between 2000 rpm and 4000 rpm depending on the amount of air humidification. It should be noted that the second speed R2 can also be set between 2000 rpm and 5000 rpm. Since the water delivery pipe 9 has an inverted conical hollow structure, the water drawn in by the rotation is lifted upwards along the inner wall of the water delivery pipe 9. Furthermore, the lifted water is discharged centrifugally from the opening 13 of the water delivery pipe 9 along the rotating plate 12, scattering as water droplets.

[0108] Water droplets scattered from the rotating plate 12 are dispersed in the space (liquid micronization chamber 7) surrounded by the collision wall 8, colliding with the collision wall 8 and being micronized. On the other hand, air passing through the liquid micronization chamber 7 moves from above the collision wall 8 towards the interior of the collision wall 8, while air containing water droplets broken (micronized) by the collision wall 8 moves from below towards the exterior of the collision wall 8. Furthermore, the air containing water droplets passes through the separator 17. Thus, the liquid micronization device 1 can humidify the air drawn in from the suction port 2 and blow out the humidified air from the exhaust port 3.

[0109] It should be noted that the liquid being micronized can be any liquid other than water, such as hypochlorous acid water with bactericidal or deodorizing properties. By including the micronized hypochlorous acid water in the air drawn in from the suction port 2 of the liquid micronization device 1 and blowing the air out from the outlet 3, the space in which the liquid micronization device 1 is placed can be sterilized or deodorized.

[0110] Next, refer to Figure 3 The details of the water blocking mechanism and drainage mechanism of the water storage section 14, which consists of the drain pipe 16 and the water supply pipe 9, are explained. Figure 3 This is a diagram illustrating the water-blocking mechanism of the water storage section, which consists of a drain pipe and a water delivery pipe, in the liquid micronization device according to Embodiment 1 of the present invention.

[0111] like Figure 3As shown, in the liquid micronization device 1, when the humidification operation begins and the rotary motor 11 (water delivery pipe 9) rotates at a first speed R1 (e.g., 2000 rpm), the centrifugal force of this rotation generates a vortex 24 in the water in the water storage section 14 inside the water delivery pipe 9. Furthermore, at the center of the vortex generated by this rotation, a gap 25 is formed between the water outlet 9a and the drain outlet 16a. Thus, the gap 25 blocks the drain outlet 16a, preventing water from the water storage section 14 from flowing into the drain outlet 16a. In other words, in the liquid micronization device 1, during the humidification operation (when the rotary motor 11 rotates at a second speed R2), it is possible to prevent water from the water storage section 14 from draining from the drain outlet 16a. As described above, the water delivery pipe 9 rotates at a speed within a specified range (e.g., a minimum of 2000 rpm and a maximum of 4000 rpm). Any speed within this specified range is a speed that ensures that water from the water storage section 14 does not flow into the drain outlet 16a.

[0112] On the other hand, if the rotation of the rotary motor 11 (water pipe 9) stops, the vortex 24 and the gap 25 disappear together, and the water in the water storage section 14 flows into the drain outlet 16a. In other words, in the liquid micronization device 1, by stopping the humidification operation (the rotation operation of the rotary motor 11), the water in the water storage section 14 can be discharged from the drain outlet 16a.

[0113] In this way, even if the drain valve is not used in the drain pipe 16, the liquid micronization device 1 can suppress (block) the water in the water storage section 14 from the drain port 16a during the humidification operation, and can discharge the water in the water storage section 14 from the drain port 16a after the humidification operation stops.

[0114] Next, refer to Figure 4 The heat exchange and ventilation device 60 equipped with the liquid micronization device 1 of this embodiment 1 will be described. Figure 4 This is a schematic perspective view of a heat exchange and ventilation device equipped with the liquid micronization device 60 of Embodiment 1.

[0115] like Figure 4 As shown, the heat exchange ventilation device 60 is configured to include a liquid atomizing device 1, a humidity recovery unit 65, and a blower 67. The heat exchange ventilation device 60 draws in external air (air whose humidity has been recovered by the humidity recovery unit 65) from the external air intake 63 and directs it through a connecting pipe 66 to the intake 2 of the liquid atomizing device 1 (see reference 67). Figure 1 Air supply. The liquid micronization device 1 humidifies the air drawn in from the intake port 2, and then blows the humidified air out from the outlet 3 (refer to...). Figure 1 The air is blown out and supplied to the room through the air supply port 64. Here, the heat exchange ventilation device 60 is equivalent to the "air supply device" of the technical solution.

[0116] The heat exchange ventilation device 60 has a box-shaped main body housing 50, for example, when placed on the floor. An internal gas intake 61, an exhaust 62, an external gas intake 63, and an air supply 64 are provided on the top surface of the main body housing 50 (the surface where the liquid atomizing device 1 is mounted). The liquid atomizing device 1 is also provided on the top surface of the main body housing 50. Furthermore, a humidity recovery unit 65 and a blower 67 are provided inside the main body housing 50.

[0117] The internal gas intake 61 is an intake port that draws air (internal gas) from inside the building into the interior of the heat exchange ventilation device 60. Specifically, the internal gas intake 61 is connected in communication with the indoor exhaust port that draws in internal gas via a pipe (not shown) extending to the ceiling or wall of each space in the building.

[0118] Exhaust port 62 is an outlet for supplying internal gas from the heat exchange ventilation device 60 to the outside. Specifically, exhaust port 62 is connected in communication with an outdoor exhaust port that blows out internal gas via a duct (not shown) extending to the exterior wall of the building.

[0119] The external gas intake 63 is an intake port that draws air (external gas) from outside the building into the interior of the heat exchange ventilation device 60. Specifically, the external gas intake 63 is connected in communication with an outdoor air supply port that draws in external gas via a pipe (not shown) extending to the exterior wall of the building.

[0120] The air supply port 64 is an outlet that delivers external air from the heat exchange ventilation device 60 to the indoor air via the liquid micronization device 1. Specifically, the air supply port 64 is connected in communication with the indoor air supply port that blows out external air via pipes (not shown) extending to the ceiling or wall surfaces of various spaces within the building.

[0121] A humidity recovery unit 65 is located upstream of the blower 67 within the main housing 50. The humidity recovery unit 65 performs humidity recovery (humidity exchange) by recovering (exchanging) the humidity of the air drawn in by the blower 67 and passing through the interior (particularly the air supply path) of the heat exchange ventilation device 60. The humidity recovery unit 65 may be, for example, a desiccant-type or heat pump-type heat exchanger.

[0122] The air supply path is not specifically illustrated. It draws in fresh outdoor air (external air) from the external air intake 63, which then passes through the humidity recovery unit 65, the blower 67, the connecting pipe 66, and the liquid micronization device 1 in sequence, and is supplied to the room from the air supply port 64.

[0123] The connecting pipe 66 connects the blower 67 to the intake port 2. Additionally, a temperature and humidity sensor 34 is installed on the connecting pipe 66, on the intake port 2 side. It should be noted that the temperature and humidity sensor 34 detects the temperature and humidity of the air flowing in the air supply path (the air drawn into the intake port 2).

[0124] The blower 67 is a device for supplying external air from the external air intake 63 to the air supply port 64. The blower 67 circulates the external air within the humidity recovery unit 65 by supplying air. Examples of blowers 67 include, for instance, crossflow fans or blower fans. It should be noted that the blower 67 is configured according to the control unit 60a (see reference 60a) of the control heat exchange ventilation device 60. Figure 5 The control signal is used to execute the air supply action.

[0125] Additionally, a water supply and drainage pipe 51 is provided on the heat exchange ventilation device 60. Water is supplied to and drained from the liquid micronization device 1 via the water supply and drainage pipe 51. Specifically, one end of the water supply and drainage pipe 51 is connected to the water supply pipe 15a of the liquid micronization device 1 (see reference 15a). Figure 2 ) and drain pipe 16 (refer to) Figure 2 The other end of the water supply and drainage pipe 51 is connected to the water supply and drainage equipment of the residence or facility, respectively.

[0126] Furthermore, the heat exchange ventilation device 60 has a control unit 60a for controlling the air supply operation of the blower 67 (see reference). Figure 5 In addition, the control unit 60a is electrically connected to the humidification control unit 30 of the liquid micronization device 1, and receives control signals from the humidification control unit 30 to control the blower 67 and the liquid micronization device 1 in a coordinated manner.

[0127] As described above, in the heat exchange ventilation device 60, during ventilation, the moisture discharged to the outside is recovered into the air supplied to the room, and if the humidity recovery unit 65 does not completely recover the moisture, when it passes through the liquid micronization device 1, the moisture can be replenished or added to it, so that the room can be maintained in a humidified and comfortable humidity range.

[0128] Next, refer to Figure 5 The humidification control unit 30 of the liquid micronization device 1 will be described. Figure 5 This is a block diagram showing the structure of the humidification control unit in the liquid micronization device according to Embodiment 1 of the present invention.

[0129] like Figure 5As shown, the humidification control unit 30 includes an input unit 30a, a storage unit 30b, a timing unit 30c, a processing unit 30d, and an output unit 30e.

[0130] The input unit 30a receives first information related to the start or stop indication from the operation panel 31, second information related to the temperature and humidity of the indoor air from the temperature and humidity sensor 32, third information related to the temperature of the outdoor air from the temperature sensor 33, fourth information related to the temperature and humidity of the air before humidification (air drawn into the intake port 2) from the temperature and humidity sensor 34, and fifth information related to the on / off state of the float switch 18a from the water level detection unit 18. The input unit 30a outputs the received first to fifth information to the processing unit 30d.

[0131] Here, the operation panel 31 is a terminal for users to input user input information (such as airflow, humidification rate, and outlet temperature) related to the liquid micronization device 1 and the heat exchange ventilation device 60, and it can be communicatively connected to the humidification control unit 30 via wireless or wired connection. It should be noted that the first information also includes user input information. Furthermore, the temperature and humidity sensor 32 is a sensor that senses the temperature and humidity of the indoor air immediately after it is drawn in from the internal air intake 61. Additionally, the temperature sensor 33 is a sensor that senses the temperature of the outdoor air immediately after it is drawn in from the external air intake 63.

[0132] The storage unit 30b stores sixth information related to humidification settings during humidification operations, seventh information related to drainage settings during drainage operations (first processing, second processing), eighth information related to drying settings during drying operations, and ninth information related to setting information corresponding to user input information. The storage unit 30b outputs the stored sixth to ninth information to the processing unit 30d.

[0133] The timing unit 30c outputs the tenth information related to the current time to the processing unit 30d.

[0134] The processing unit 30d receives first to fifth information from the input unit 30a, sixth to ninth information from the storage unit 30b, and tenth information from the timing unit 30c. Using the received first to tenth information, the processing unit 30d determines control information related to humidification operations based on humidification settings, drainage operations based on drainage settings (first processing, second processing), and drying operations in drying settings. The processing unit 30d outputs the determined control information to the output unit 30e.

[0135] Output unit 30e receives control information from processing unit 30d. Output unit 30e is electrically connected to heat exchange ventilation device 60 (control unit 60a, blower 67), rotary motor 11, and water supply valve 15b. Furthermore, based on the received control information, output unit 30e outputs signals (control signals) to control the air supply operation of blower 67, the humidification operation in liquid micronization chamber 7 (rotation operation of rotary motor 11), and the opening and closing operation of water supply valve 15b.

[0136] Furthermore, the heat exchange ventilation device 60 (control unit 60a, blower 67) receives signals from the output unit 30e, and the control unit 60a executes control of the blower 67 according to the received signals. In addition, the rotary motor 11 and the water supply valve 15b respectively receive signals from the output unit 30e and execute their respective controls according to the received signals.

[0137] As described above, the humidification control unit 30 controls the humidification action in the humidification process, the drainage action in the first or second process, and the drying action in the drying process.

[0138] Next, refer to Figures 6-10 The processing steps in the humidification operation of the liquid micronization device 1 are explained. Figure 6 , Figure 7 This is a flowchart illustrating the humidification process of the liquid micronization device based on Embodiment 1 of the present invention. Figure 8 This is a flowchart illustrating the water supply treatment steps of the liquid micronization device based on Embodiment 1 of the present invention. Figure 9 This is a flowchart illustrating the water micronization process of the liquid micronization device based on Embodiment 1 of the present invention. Figure 10 This is a flowchart illustrating the drainage treatment steps of the liquid micronization device based on Embodiment 1 of the present invention. It should be noted that, below, the case where the blower 67 performs the air supply operation based on a control signal from the humidification control unit 30, rather than a control signal from the control unit 60a, will be described.

[0139] If a control signal related to the start of humidification operation of the liquid micronization device 1 is input to the humidification control unit 30, then as follows Figure 6As shown, firstly, the humidification control unit 30 activates the blower 67, initiating airflow from the blower 67 (step S01). This allows air to circulate within the liquid atomizing device 1 (liquid atomizing chamber 7). Then, the humidification control unit 30 resets the water level detection counter N, setting it to "0" (step S02). Here, the water level detection counter N represents the number of times water has been supplied to the water storage unit 14 (the number of times water supply has been performed until the water storage unit 14 is full). Furthermore, the humidification control unit 30 performs the water supply process to supply water to the water storage unit 14 (step S03).

[0140] In water supply treatment, such as Figure 8 As shown, the humidification control unit 30 operates the rotary motor 11 at a first speed R1 (e.g., 2000 rpm), activating the water-blocking mechanism (step S20). Next, the humidification control unit 30 opens the water supply valve 15b of the water supply unit 15, starting to supply water to the water storage unit 14 (step S21). Furthermore, the humidification control unit 30 determines whether the water level in the water storage unit 14 is full based on the fifth information from the water level detection unit 18 (step S22). As a result, if the water level in the water storage unit 14 is not full (step S22 "No"), the humidification control unit 30 continues to supply water to the water storage unit 14 (returning to step S22). On the other hand, if the water level in the water storage unit 14 is full (step S22 "Yes"), the humidification control unit 30 closes the water supply valve 15b, stopping the supply of water to the water storage unit 14 (step S23). Furthermore, the humidification control unit 30 increments the water level detection counter N by "1" (step S24). Through the above steps, the water supply process for supplying water to the water storage unit 14 is completed. However, the water supply process ends while the rotary motor 11 is rotating at a first speed R1. Return Figure 6 .

[0141] If the water supply process (step S03) for supplying water to the water storage unit 14 is completed, the humidification control unit 30 performs water micro-processing (step S04) as a humidification operation in the humidification process.

[0142] In water micro-treatment, such as Figure 9As shown, the humidification control unit 30 determines whether humidification (water refinement) is needed based on the first information from the operation panel 31 and the fourth information from the temperature and humidity sensor 34 (step S30). As a result, if humidification is needed ("Yes" in step S30), the humidification control unit 30 rotates the rotary motor 11 at a second speed R2, initiating a humidification operation (water refinement operation) based on the humidification setting (step S31). Here, the second speed R2 is a speed determined by the humidification conditions (e.g., the amount of humidification towards the target humidity), and is set to at least a speed of the first speed R1 or higher. Furthermore, it determines whether a predetermined time (fifth time T5) has elapsed since the start time of the rotary motor 11's operation in step S31 (step S32). As a result, if the fifth time T5 has not elapsed ("No" in step S32), the humidification control unit 30 continues the water refinement operation (returning to step S32). On the other hand, after the fifth time T5 has elapsed ("Yes" in step S32), the humidification control unit 30 continues to perform water micro-refinement operations and proceeds to the next step (step S05). Here, the fifth time T5 is the interval time for feedback control of humidification, for example, set to 5 minutes.

[0143] On the other hand, if the determination in step S30 indicates that humidification is not required (No in step S30), the humidification control unit 30 operates the rotary motor 11 at a fourth rotational speed R4 (e.g., 2000 rpm), at least ensuring the water-blocking mechanism is functioning (step S33). It should be noted that the fourth rotational speed R4 is maintained even when the rotary motor 11 is already rotating. Furthermore, it is determined whether a predetermined time (sixth time T6) has elapsed since the start time of the rotary motor 11's operation or operation maintenance in step S33 was used as the starting time (step S34). As a result, if the sixth time T6 has not elapsed (No in step S34), the humidification control unit 30 continues in the water-blocking state (returning to step S34). On the other hand, if the sixth time T6 has elapsed (Yes in step S34), the humidification control unit 30 proceeds to the next step (step S35). Here, the sixth time T6 is the interval time for feedback control of humidification, for example, set to 5 minutes. It should be noted that the fifth time T5 (more precisely, the time after adding the time required for water supply in step S06 to the fifth time T5) or the sixth time T6 is equivalent to the "first period" of the technical solution.

[0144] Next, a determination is made (step S35) as to whether the time taken from the start time of the rotary motor 11 in step S33 has elapsed for a predetermined time (seventh time T7). As a result, if the seventh time T7 has not elapsed (step S35: "No"), the humidification control unit 30 returns to step S30 while rotating the rotary motor 11 at the fourth speed R4, and again determines whether humidification is needed. On the other hand, if the seventh time T7 has elapsed (step S35: "Yes"), the humidification control unit 30 stops the rotary motor 11 (step S36). Furthermore, the humidification control unit 30 returns to step S02 and restarts the humidification process of the liquid micronization device 1. Here, the seventh time T7 is set to, for example, 2 hours. Additionally, the seventh time T7 corresponds to the "second period" of the technical solution. Figure 6 .

[0145] If the water atomization process (step S04) ends, while the water atomization operation continues, a determination is made as to whether a predetermined time (first time T1) has elapsed since the start time of the rotation motor 11 in step S31 (step S05). If the first time T1 has elapsed ("Yes" in step S05), the humidification control unit 30 performs water supply processing to supply water to the water storage unit 14 (see [reference]). Figure 8 The humidification control unit 30 fills the water storage section 14 with water (step S06). On the other hand, if the first time T1 has not elapsed (No in step S05), the humidification control unit 30 continues to perform water miniaturization operations (return to step S05). Here, the first time T1 is a time set to estimate the amount of water reduction in the water storage section 14 due to the humidification operation, for example, it is set to 30 minutes.

[0146] Next, after a predetermined time (second time T2) starting from step S02 has elapsed ("Yes" in step S07), the humidification control unit 30 executes step S10 (refer to...). Figure 7The process continues after step S10. Here, the second time T2 is the time when the reset time of the water level detection counter N in step S02 is used as the start time, for example, it is set to 24 hours. It should be noted that the second time T2 can also be the time after the liquid micronization device 1 is started or the time after the last drying operation. On the other hand, if the second time T2 has not passed (No in step S07), the humidification control unit 30 determines, based on the water level detection counter N, whether the number of times the water supply to the full water state has exceeded M times (for example, 10 times) (step S08). As a result, if the water level detection counter N has not exceeded M times (No in step S08), the process returns to step S04, and the humidification control unit 30 repeatedly performs the humidification operation. On the other hand, if the water level detection counter N has exceeded M times (Yes in step S08), the humidification control unit 30 performs the drainage process of the water in the water storage unit 14 (step S09). Here, the processes in steps S08 and S09 become the drainage actions corresponding to the first process.

[0147] In drainage treatment, such as Figure 10 As shown, the humidification control unit 30 stops the rotary motor 11, rendering the water-blocking mechanism inactive (step S40). This initiates the drainage of water from the water storage unit 14. Furthermore, it determines whether a predetermined time (eighth time T8) has elapsed since the start time of the rotary motor 11's stop in step S40 (step S41). If the eighth time T8 has not elapsed (step S41: "No"), the humidification control unit 30 continues the drainage process (returning to step S41). Conversely, if the eighth time T8 has elapsed (step S41: "Yes"), the humidification control unit 30 considers the water in the water storage unit 14 to have been drained, ending the drainage process. Here, the eighth time T8 is the time it takes for the water in the water storage unit 14 to be reliably drained (even from a full state), for example, set to 1 minute. Figure 6 .

[0148] If the drainage process of the water in the water storage unit 14 (step S09) is completed, the humidification control unit 30 returns to step S02 and repeats the subsequent steps.

[0149] Then, refer to Figure 7 The following describes step S10 performed after the second time T2 has elapsed, as well as the processing after step S10.

[0150] If the second time interval T2 has elapsed (step S07 "Yes"), then... Figure 7 As shown, the humidification control unit 30 performs drainage treatment of the water in the water storage unit 14 (see reference). Figure 10(Step S10). Here, the processes in steps S07 and S10 become the drainage operation corresponding to the second process. Furthermore, if the drainage process of the water in the water storage unit 14 (step S10) is completed, the humidification control unit 30 rotates the rotary motor 11 at a third speed R3 (e.g., 2000 rpm) to start the first drying operation (a finer operation in the state where there is no water in the water storage unit 14) (step S11). Furthermore, if a predetermined time (third time T3) has elapsed since the start of the first drying operation ("Yes" in step S12), the humidification control unit 30 stops the rotary motor 11 (step S13). On the other hand, if the third time T3 has not elapsed ("No" in step S12), the humidification control unit 30 continues the first drying operation (return to step S12). That is, in the first drying operation, the rotation of the water delivery pipe 9 is performed in the state where there is no water in the water storage unit 14 to remove water droplets that remain attached to the water delivery pipe 9, etc. It should be noted that the third time T3 is the water droplet removal time based on the rotation of the water pipe 9, for example, it is set to 30 seconds.

[0151] If the first drying operation ends, a second drying operation begins, in which air circulates within the liquid micronization device 1 (liquid micronization chamber 7) while the micronization operation is stopped. Furthermore, if a predetermined time (fourth time T4) has not elapsed since the start of the second drying operation (step S14 "No"), the humidification control unit 30 continues the second drying operation (returning to step S14). In other words, during the second drying operation, ventilation is performed into the liquid micronization device 1 (liquid micronization chamber 7) to complete the drying within the device (removal of moisture remaining within the device). It should be noted that the fourth time T4 is the drying time based on ventilation within the device, for example, set to 1 hour. On the other hand, if the fourth time T4 has elapsed (step S14 "Yes"), the humidification control unit 30 determines whether a control signal related to the cessation of the humidification process of the liquid micronization device 1 has been input (step S15). As a result, if no control signal related to stopping the humidification process is input (No in step S15), the humidification control unit 30 returns to step S02 and restarts the humidification process of the liquid micronization device 1. On the other hand, if a control signal related to stopping the humidification process is input (Yes in step S15), the humidification control unit 30 stops the blower 67 (step S16). Furthermore, the humidification control unit 30 terminates the humidification process of the liquid micronization device 1. Thus, the liquid micronization device 1 enters a state awaiting an operation start instruction from the operation panel 31.

[0152] Here, the processes in the first drying operation (steps S11 to S13) and the second drying operation (steps S13 to S14) are called drying operations.

[0153] Furthermore, the first speed R1, the second speed R2 (the minimum speed range of 2000 rpm), the third speed R3, and the fourth speed R4 are equivalent to the "first speed" in the technical solution. The second speed R2 (the maximum speed range of 4000 rpm) is equivalent to the "second speed" in the technical solution. The second speed R2 (the speed range of 2000 rpm-4000 rpm) is equivalent to the "third speed" in the technical solution.

[0154] As described above, the heat exchange ventilation device 60 performs each process in the humidification operation of the liquid micronization device 1.

[0155] The liquid micronization device 1 according to Embodiment 1 can achieve the following effects.

[0156] (1) In the liquid atomizing device 1, the humidification control unit 30, upon determining that the humidity of the air drawn in from the intake port 2 exceeds the target humidity (the amount of humidification towards the target humidity), controls the water delivery pipe 9 to rotate at a fourth rotational speed R4 (2000 rpm). Therefore, during the humidification operation (water atomization operation), even when the humidity of the air drawn in from the intake port 2 is determined to exceed the target humidity, the liquid atomizing device 1 rotates the water delivery pipe 9 at a fourth rotational speed R4, thus suppressing the discharge of water from the water storage unit 14. Therefore, even in situations where the humidity repeatedly exceeds or falls below the target humidity, the liquid atomizing device 1 can reliably prevent water from flowing out of the water storage unit 14, reducing the amount of water discharged. In other words, by performing feedback control of the humidification amount during the humidification operation, the liquid atomizing device 1 can reduce the amount of water used.

[0157] (2) In the liquid micronization device 1, the humidification control unit 30 controls the water pipe 9 to rotate at a second rotation speed R2 (2000rpm-4000rpm) when the humidity of the air drawn in from the suction port 2 is insufficient to the target humidity. Thus, in the feedback control of the humidification amount, the liquid micronization device 1 can humidify to the target humidity as necessary when the humidity of the air drawn in from the suction port 2 is insufficient to the target humidity.

[0158] (3) In the liquid micronization device 1, the humidification control unit 30 controls the humidification by determining whether the humidity of the air drawn in from the inlet 2 exceeds the target humidity at each predetermined time (the fifth time T5 or the sixth time T6). Thus, in the case of feedback control of the humidification amount during the humidification operation, the adjustment of the humidification amount is performed at each predetermined time. Therefore, even if the humidity of the air drawn in from the inlet 2 changes drastically due to some reason (e.g., bathroom use), the humidification amount can be effectively adjusted towards the target humidity.

[0159] (4) In the liquid micronization device 1, the humidification control unit 30 controls the rotation of the water delivery pipe 9 (rotary motor 11) to stop if the humidity of the air drawn in from the suction port 2 exceeds the target humidity for a seventh time T7. Thus, humidification of the air drawn in from the suction port 2 is stopped when the indoor air reaches the target humidity for a seventh time T7. In other words, during the period from stopping humidification to resuming humidification, the amount of water consumed corresponding to the water volume (humidification amount) due to humidification caused by the rotation of the fourth speed R4 (2000 rpm) is reduced.

[0160] (5) In the heat exchange ventilation device 60, the humidity recovery unit 65 is positioned upstream of the liquid micronizer 1 during the airflow through the liquid micronizer 1 and the humidity recovery unit 65. That is, in the liquid micronizer 1, the humidity recovery unit 65 is configured to allow air whose humidity has been recovered by the humidity recovery unit 65 to flow into the intake port 2. Therefore, the air whose humidity has been recovered by the humidity recovery unit 65 flows into the liquid micronizer 1 (intake port 2), thus enabling more appropriate control of indoor humidity. Furthermore, by controlling humidity at both the humidity recovery unit 65 and the liquid micronizer 1, sufficient humidification can be ensured even when no heater is installed in the humidity recovery unit 65 or the liquid micronizer 1. Additionally, energy savings can be achieved by eliminating the need for a heater to ensure sufficient humidification.

[0161] (6) The liquid micronization device 1 is configured such that, during the humidification operation (micronization operation), when the number of times water is supplied to the water storage unit 14 reaches a predetermined number (more than M times), a first process of draining the water from the water storage unit 14 is performed. In the first process, since the water in the water storage unit 14 is drained every predetermined number of water supplies, the amount of water used can be reduced compared to draining water every time. The predetermined number of times is two or more times.

[0162] (7) In the liquid micronization device 1, during the humidification operation (micronization operation), if the number of times water is supplied to the water storage unit 14 reaches a predetermined number (more than M times), a first process of draining the water from the water storage unit 14 is performed. Thus, if the number of times water is supplied to the water storage unit 14 during the humidification operation reaches a predetermined number (more than M times), the execution of the first process drains and removes the water (water in a state where scale components such as calcium and magnesium are concentrated) from the water storage unit 14. Therefore, the increase in the concentration of scale components in the water within the water storage unit 14 can be suppressed.

[0163] (8) In the liquid micronization device 1, a second process is performed to drain the water from the water storage unit 14 when the humidification operation (micronization operation) has been continued for a predetermined time (second time T2). Therefore, even when the humidification operation has been continued for the predetermined time (second time T2), the water in the water storage unit 14 (water in a state where scale components are concentrated) is drained and removed by performing the second process. In other words, in the liquid micronization device 1, the increase in the concentration of scale components in the water within the water storage unit 14 can be reliably suppressed by either the first or second process.

[0164] (9) In the liquid micronization device 1, after the second process is completed, a humidification operation (micronization operation) is performed in the water storage section 14 when there is no water, and a drying process is performed by air supplied from the blower 67. As a result, since the inside of the device can be dried, the growth of mold or bacteria in the device can be suppressed even when the liquid micronization device 1 is kept in a stopped state for a long time.

[0165] (Implementation Method 2)

[0166] Conventional liquid micronization devices exist that atomize water, infuse the intake air with the atomized water, and then blow it out (e.g., Patent Document 2). In such conventional liquid micronization devices, a liquid micronization chamber for atomizing water is provided in the air passage between the intake air inlet and the outlet for blowing out the intake air. The liquid micronization chamber has a water delivery pipe fixed to the rotating shaft of a rotary motor. The rotary motor rotates the water delivery pipe, and water stored in the water storage section is supplied to the water delivery pipe for atomization. The atomized water is then emitted centrifugally. The emitted water passes through a porous section, thus atomizing the water. Furthermore, in conventional liquid micronization devices, the water level in the water storage section is detected during operation, and an automatic water supply valve is controlled to maintain the water level in the water storage section at a predetermined level.

[0167] However, in the existing liquid micronization device described in Patent Document 2, if humidification is continuously performed while automatically supplying water, only water in the water storage section is vaporized, and scale components such as calcium and magnesium contained in the water supplied in proportion to the usage time and water volume are concentrated. As a result, scale components contained in the agitated water precipitate in the porous section, which may cause blockage of the porous section. In addition, such concerns about blockage may also occur in liquid micronization devices equipped with a separator for capturing water droplets contained in the air passing through the liquid micronization chamber.

[0168] This embodiment was made to solve the above-mentioned problems, and provides a liquid micronization device that can suppress the generation of blockages in the device during long-term continuous use.

[0169] The liquid atomizing device of this embodiment is a device that contains atomized liquid in air drawn in through an inlet and blown out through an outlet. The liquid atomizing device includes: a cylindrical liquid-lifting pipe with a liquid-lifting port in the vertical direction below, from which liquid drawn in from the liquid-lifting port is discharged centrifugally as the rotating shaft rotates; a collision wall that atomizes the liquid by colliding with the liquid discharged from the liquid-lifting pipe; a storage unit disposed in the vertical direction below the liquid-lifting pipe and storing the liquid drawn in by the liquid-lifting pipe; a separator disposed between the collision wall and the storage unit that captures a portion of the atomized liquid droplets; and a control unit that controls the atomization operation of the liquid in the liquid atomizing device. Furthermore, the inlet is connected to an air supply device having a humidity recovery unit. When the number of times the liquid is supplied to the storage unit during the atomization operation reaches a predetermined number, the control unit performs a first process of discharging the liquid from the storage unit.

[0170] With this structure, when the liquid is supplied to the storage section a predetermined number of times during the micro-fine-refinement operation, the liquid in the storage section (e.g., water in a state where scale components are concentrated) is discharged and removed through the execution of the first process. Therefore, the increase in the concentration of scale components in the liquid within the storage section can be suppressed. As a result, during subsequent micro-fine-refinement operations, the amount of scale components contained in the liquid in the storage section entering the separator can be reduced. In other words, even with prolonged continuous use of the device, it can become a liquid micro-fine-refinement device that can suppress the generation of blockages within the device.

[0171] Furthermore, in the liquid micronization apparatus of this embodiment, it is preferable that the control unit performs a second process to discharge the liquid from the storage unit while the micronization operation continues for a predetermined period (second time). In this way, even if the micronization operation continues for a second time, the liquid in the storage unit (e.g., water in a state where scale components are concentrated) can be discharged and removed by performing the second process. In other words, by performing either the first or second process, the increase in the concentration of scale components in the liquid within the storage unit can be reliably suppressed.

[0172] Furthermore, in the liquid micronization apparatus of the present invention, it is preferable that the control unit performs the micronization operation after the second processing is completed, with no liquid in the storage unit, and performs a third processing of air supply from the air supply device. In this way, after the third processing is completed, the apparatus can be dried, thus suppressing the growth of mold or other microorganisms within the apparatus even when the liquid micronization apparatus is kept in a stopped state for an extended period.

[0173] Furthermore, the liquid micronization apparatus of the present invention also includes a drain port for discharging liquid from the bottom surface of the storage section. During the micronization operation, the liquid in the storage section is vortexed by rotation inside the drain pipe. A gap is formed at the center of this vortex, connecting the drain port and the discharge port, preventing the liquid in the storage section from flowing to the discharge port. The control unit stops rotating to discharge the liquid in the first or second process. In this way, even without using a drain valve, the storage and discharge of liquid in the liquid micronization apparatus can be performed. Therefore, since the opening area of ​​the drain port can be increased, or the inner diameter of the drain pipe can be thickened, a liquid micronization apparatus that is less prone to clogging caused by the drain mechanism can be achieved.

[0174] The liquid micronization device 1 of this embodiment is structurally the same as the liquid micronization device 1 of Embodiment 1. However, the liquid micronization device 1 of this embodiment may not include the temperature and humidity sensor 34.

[0175] Reference Figures 11-14 The processing steps in the humidification operation of the liquid micronization device 1 are explained. Figure 11 and Figure 12 This is a flowchart illustrating the humidification process of the liquid micronization device based on Embodiment 2 of the present invention. Figure 13 This is a flowchart illustrating the water supply treatment steps of the liquid micronization device based on Embodiment 2 of the present invention. Figure 14 This is a flowchart illustrating the drainage treatment steps of the liquid micronization device based on Embodiment 2 of the present invention. It should be noted that, below, the case where the blower 67 performs the air supply operation based on a control signal from the humidification control unit 30, rather than a control signal from the control unit 60a, will be described.

[0176] like Figure 11 As shown, if a control signal related to the start of humidification operation of the liquid atomizing device 1 is input to the humidification control unit 30, the humidification control unit 30 first activates the blower 67, starting airflow from the blower 67 (step S51). As a result, air circulates within the liquid atomizing device 1 (liquid atomizing chamber 7). Furthermore, the humidification control unit 30 resets the water level detection counter N, setting it to "0" (step S52). Here, the water level detection counter N represents the number of times water is supplied to the water storage unit 14 (the number of times water is supplied until the water storage unit 14 is full). Then, the humidification control unit 30 performs the water supply process to supply water to the water storage unit 14 (step S53).

[0177] In water supply treatment, such as Figure 13As shown, the humidification control unit 30 operates the rotary motor 11 at a first speed R1 (e.g., 2000 rpm), activating the water-blocking mechanism (step S70). Next, the humidification control unit 30 opens the water supply valve 15b of the water supply unit 15, starting to supply water to the water storage unit 14 (step S71). Furthermore, the humidification control unit 30 determines whether the water level in the water storage unit 14 is full based on fifth information related to the on / off state of the float switch 18a from the water level detection unit 18 (step S72). As a result, if the water level in the water storage unit 14 is not full (step S72 "No"), the humidification control unit 30 continues to supply water to the water storage unit 14 (return to step S72). On the other hand, if the water level in the water storage unit 14 is full (step S72 "Yes"), the humidification control unit 30 closes the water supply valve 15b, stopping the supply of water to the water storage unit 14 (step S73). Furthermore, the humidification control unit 30 increments the water level detection counter N by "1" (step S74). Through the above steps, the water supply process for supplying water to the water storage unit 14 is completed. However, the water supply process ends while the rotary motor 11 is rotating at a first speed R1. Return Figure 11 .

[0178] If the water supply process (step S53) of supplying water to the water storage unit 14 ends, the humidification control unit 30 causes the rotary motor 11 to rotate at a second speed R2, starting the humidification operation (humidification run) based on the humidification setting (step S54). Here, the second speed R2 is a speed determined by the humidification conditions (e.g., humidification amount), and is set to a speed at least equal to or greater than the first speed R1. Furthermore, during the humidification operation, if a predetermined time (first time T1) starting from step S54 has elapsed ("Yes" in step S55), the humidification control unit 30 performs the water supply process of supplying water to the water storage unit 14 (see [reference]). Figure 13 The water storage unit 14 is filled with water (step S56). On the other hand, if the first time T1 has not elapsed (No in step S55), the humidification control unit 30 continues to humidify (return to step S55). Here, the first time T1 is the time that is counted starting from the moment the rotary motor 11 operates in step S54, for example, it is set to 30 minutes.

[0179] Next, after a predetermined time (second time T2) starting from step S52 has elapsed ("Yes" in step S57), the humidification control unit 30 executes step S60 (refer to...). Figure 12The process continues after step S60. Here, the second time T2 is the time counted starting from the reset time of the water level detection counter N in step S52, for example, set to 24 hours. It should be noted that the second time T2 can also be the time after the liquid micronization device 1 starts or the time after the last drying operation. On the other hand, if the second time T2 has not elapsed (step S57 "No"), the humidification control unit 30 determines, based on the water level detection counter N, whether the number of times water is supplied to a full water state exceeds M times (e.g., 10 times) (step S58). As a result, if the water level detection counter N has not exceeded M times (step S58 "No"), the process returns to step S54, and the humidification control unit 30 repeatedly performs the humidification operation. On the other hand, if the water level detection counter N exceeds M times (step S58 "Yes"), the humidification control unit 30 performs the drainage process of the water in the water storage unit 14 (step S59). Here, the processes in steps S58 and S59 become the drainage actions corresponding to the first process.

[0180] In drainage treatment, such as Figure 14 As shown, the humidification control unit 30 stops the rotary motor 11, rendering the water-blocking mechanism inactive (step S80). This initiates the drainage of water from the water storage unit 14. During water drainage, if a predetermined time (eighth time T8) starting from step S80 has not elapsed (step S81 "No"), the humidification control unit 30 continues draining water (returning to step S81). On the other hand, if the eighth time T8 has elapsed (step S81 "Yes"), the humidification control unit 30 considers the water in the water storage unit 14 to be drained, ending the drainage process of the water storage unit 14. Here, the eighth time T8 is the time counted starting from the moment the rotary motor 11 stops in step S80, for example, set to 1 minute. Figure 11 .

[0181] If the drainage process of the water in the water storage unit 14 (step S59) is completed, the humidification control unit 30 returns to step S52 and repeats the subsequent steps.

[0182] Then, refer to Figure 12 The following describes step S60 performed after the second time T2 has elapsed, as well as the processing after step S60.

[0183] If the second time interval T2 has elapsed (as indicated by "Yes" in step S57), then... Figure 12 As shown, the humidification control unit 30 performs drainage treatment of the water in the water storage unit 14 (see reference). Figure 14(Step S60). Here, the processing in steps S57 and S60 becomes a drainage operation corresponding to the second processing. Furthermore, if the drainage process of the water in the water storage unit 14 (step S60) is completed, the humidification control unit 30 rotates the rotary motor 11 at a third speed R3 (e.g., 2000 rpm) to start the first drying operation (a finer operation when the water storage unit 14 is empty) (step S61). If a predetermined time (third time T3) has elapsed since the start of the first drying operation ("Yes" in step S62), the humidification control unit 30 stops the rotary motor 11 (step S63). On the other hand, if the third time T3 has not elapsed ("No" in step S62), the humidification control unit 30 continues the first drying operation (returning to step S62). In other words, during the first drying operation, the rotation of the water delivery pipe 9 is performed when there is no water in the water storage unit 14 to remove water droplets remaining on the water delivery pipe 9, etc. It should be noted that the third time T3 is set to, for example, 30 seconds.

[0184] If the first drying operation ends, and the micronization operation stops, a second drying operation begins, in which air circulates within the liquid micronization device 1 (liquid micronization chamber 7). Furthermore, if no predetermined time (fourth time T4) has elapsed since the start of the second drying operation (step S64 "No"), the humidification control unit 30 continues the second drying operation (returning to step S64). In other words, during the second drying operation, ventilation is performed into the liquid micronization device 1 (liquid micronization chamber 7) to dry the device (remove residual moisture). It should be noted that the fourth time T4 is, for example, set to 1 hour. On the other hand, if the fourth time T4 has elapsed (step S64 "Yes"), the humidification control unit 30 determines whether a control signal related to the cessation of the humidification process of the liquid micronization device 1 has been input (step S65). As a result, if no control signal related to stopping the humidification process is input (No in step S65), the humidification control unit 30 returns to step S52 and restarts the humidification process of the liquid micronization device 1. On the other hand, if a control signal related to stopping the humidification process is input (Yes in step S65), the humidification control unit 30 stops the blower 67 (step S66). Furthermore, the humidification control unit 30 terminates the humidification process of the liquid micronization device 1. Thus, the liquid micronization device 1 enters a state awaiting the start-up instruction from the operation panel 31.

[0185] Here, the processes in the first drying operation (steps S61 to S63) and the second drying operation (steps S63 to S64) become the drying actions corresponding to the third process.

[0186] As described above, the heat exchange ventilation device 60 performs each process in the humidification operation of the liquid micronization device 1.

[0187] The liquid micronization device 1 according to Embodiment 2 can achieve the following effects.

[0188] (1) In the liquid micronization device 1, it is configured such that, during the humidification operation (micronization operation), if the number of times water is supplied to the water storage unit 14 reaches a predetermined number (more than M times), a first process of draining the water from the water storage unit 14 is performed. Thus, during the humidification operation, if the number of times water is supplied to the water storage unit 14 reaches a predetermined number (more than M times), by performing the first process, the water in the water storage unit 14 (water in a state where scale components are concentrated) is drained and removed. Therefore, the increase in the concentration of scale components in the water within the water storage unit 14 can be suppressed. As a result, during subsequent humidification operations, the amount of scale components contained in the water in the water storage unit 14 entering the separator 17 can be reduced. In other words, even with prolonged continuous use of the device, the liquid micronization device 1 can suppress the generation of blockages within the device.

[0189] (2) The liquid micronization device 1 is configured such that, during the humidification operation (micronization operation), when the number of times water is supplied to the water storage unit 14 reaches a predetermined number (more than M times), a first process of draining the water from the water storage unit 14 is performed. In this first process, since the water in the water storage unit 14 is drained every predetermined number of water supplies, the amount of water used can be reduced compared to draining water every time. Therefore, the operating cost of the liquid micronization device 1 can be reduced. The predetermined number of times is two or more times.

[0190] (3) In the liquid micronization device 1, a second process is performed to drain the water from the water storage unit 14 after the humidification operation (micronization operation) has been continued for a predetermined time (second time T2). Thus, by performing the second process after the humidification operation has been continued for the predetermined time (second time T2), the water (water in a state where scale components are concentrated) in the water storage unit 14 is drained and removed. In other words, in the liquid micronization device 1, the increase in the concentration of scale components in the water within the water storage unit 14 can be reliably suppressed through either the first or second process.

[0191] (4) In the liquid micronization device 1, after the second treatment is completed, a humidification operation (micronization operation) is performed in the water storage section 14 when there is no water, and a third treatment of air supply from the blower 67 is performed. As a result, after the third treatment is completed, the device can be dried, and thus the growth of mold or bacteria in the device can be suppressed when the liquid micronization device 1 is kept in a stopped state for a long time.

[0192] (5) In the liquid micronization device 1, during the humidification operation (micronization operation), the water in the water storage section 14 is generated by rotation inside the water delivery pipe 9, creating a vortex 24. A gap 25 is formed at the center of this vortex, connecting the water delivery port 9a and the drain port 16a, thus blocking the water in the water storage section. Furthermore, by stopping the rotation of the rotary motor 11, the water in the first or second processing is discharged. With this configuration, the liquid micronization device 1 can perform water blocking and drainage even without using a drain valve. Therefore, since the opening area of ​​the drain port 16a can be increased, or the inner diameter of the drain pipe 16 can be thickened, the liquid micronization device 1 can be made less prone to blockage caused by the drainage mechanism.

[0193] (6) In the liquid micronization device 1, the bottom surface of the water storage section 14 is formed in the shape of a mortar, inclined downward toward the water outlet 9a. Therefore, when the water outlet pipe 9 rotates, centrifugal force can be easily applied to the water stored in the water storage section 14. Thus, a vortex 24 can be easily generated in the water in the water storage section 14 inside the water outlet pipe 9, and the generated vortex 24 can be stably maintained. Furthermore, when the rotation of the water outlet pipe 9 is stopped, the water stored in the water storage section 14 can be reliably discharged from the drain outlet 16a.

[0194] (7) In the heat exchange ventilation device 60, the humidity recovery unit 65 is positioned upstream of the liquid micronizer 1 in the airflow passing through the liquid micronizer 1 and the humidity recovery unit 65. In other words, in the heat exchange ventilation device 60, the liquid micronizer 1 is positioned downstream of the humidity recovery unit 65. At this time, the air after humidity recovery by the humidity recovery unit 65 flows into the liquid micronizer 1, thus enabling more appropriate humidity control. Furthermore, by performing humidity control at both the humidity recovery unit 65 and the liquid micronizer 1, sufficient humidification can be ensured even when neither the humidity recovery unit 65 nor the liquid micronizer 1 is equipped with a heater. In addition, a heater is not required to ensure humidification, thereby achieving energy savings.

[0195] The present invention has been described above based on the embodiments. However, it is easy to infer that the present invention is not limited to the above embodiments, and various modifications and variations can be made without departing from the spirit of the invention. For example, the values ​​listed in the above embodiments are just examples, and other values ​​can certainly be used.

[0196] In the heat exchange ventilation device 60, the humidity recovery unit 65 is configured to not only recover (exchange) humidity but also recover (exchange) temperature. Specifically, the humidity recovery unit 65 is used as a total heat exchange element, and an exhaust fan is installed inside the main housing 50 to form an exhaust air path. The exhaust air path is a path that draws in indoor air from the internal gas intake 61 through the exhaust fan and exhausts it to the outside through the exhaust port 62 via the humidity recovery unit 65. At this time, the humidity recovery unit 65 is positioned at the intersection of the exhaust air path and the supply air path. Furthermore, the humidity recovery unit 65 performs heat exchange and humidity exchange between the air passing through the exhaust air path and the air passing through the supply air path. As a result, more comfortable air can be supplied to the room.

[0197] Furthermore, in the heat exchange ventilation device 60, to prevent the air whose humidity has been recovered by the humidity recovery unit 65 from flowing through the liquid atomizing device 1, it can be configured to bypass the liquid atomizing device 1 and be supplied to the room. Thus, when the liquid atomizing device 1 is not operating and only heat exchange ventilation is running, the air with recovered humidity can be supplied to the room efficiently. In addition, since the increase in pressure loss caused by the liquid atomizing device 1 can be suppressed, energy-saving operation can be achieved throughout the year.

[0198] Furthermore, in the heat exchange ventilation device 60, the operation of the blower 67 is stopped by stopping the air supply from the blower 67, but this is not the only method. For example, by switching to the bypass described above, the air supply to the liquid micronization device 1 can be stopped. As a result, the drying operation in the drying process can be performed independently while supplying air to the room.

[0199] Furthermore, in the liquid micronization device 1, the humidification control unit 30 controls the supply of water to the water storage unit 14 when the water level detection unit 18 remains disconnected for a predetermined time (first time T1), and this is not limited to this. For example, the humidification control unit 30 may also control the supply of water to the water storage unit 14 when the amount of water reduction in the water storage unit 14 due to the humidification operation reaches a predetermined water volume V. In this case, to determine whether the predetermined water volume V has been reached, the estimated amount of water reduced corresponding to the humidification conditions (humidification amount, air volume) during the humidification operation is calculated at regular intervals (e.g., 1 minute or 5 minutes), and these are accumulated for judgment. As a result, since the management accuracy of the water volume (or remaining amount) in the water storage unit 14 can be improved, unnecessary water supply (water supply when the water in the water storage unit 14 has not decreased) can be suppressed.

[0200] Furthermore, in the liquid micronization device 1, the humidification control unit 30 can control the rotation of the water delivery pipe 9 (rotary motor 11) by stopping it when it determines that the humidity of the air drawn in from the intake port 2 exceeds the target humidity, and when the humidity of the air drawn in from the intake port 2 becomes a first humidity higher than the target humidity. Here, the first humidity is set, for example, to 120% of the target humidity. In this way, the humidification control unit 30 can suppress excessive humidification of the air drawn in from the intake port 2, and thus can more appropriately control the humidity in the room.

[0201] In addition, in the liquid micronization device 1, the humidification control unit 30 determines whether humidification (water micronization) is needed based on the first information from the operation panel 31 and the fourth information from the temperature and humidity sensor 34, specifically as described below.

[0202] First, the humidification control unit 30 calculates the amount of humidification required to achieve the target humidity based on the first information (target humidity, air exchange rate) from the operation panel 31 and the fourth information (temperature and humidity of the air drawn into the intake port 2) from the temperature and humidity sensor 34. Furthermore, the humidification control unit 30 calculates the rotational speed of the rotary motor 11 to achieve the calculated humidification amount. As a result, if the calculated rotational speed of the rotary motor 11 is less than 2000 rpm, the humidification control unit 30 determines that humidification is not needed; if it is 2000 rpm or more, it determines that humidification is needed. Furthermore, if the calculated rotational speed is within the range of 2000 rpm to 4000 rpm, the humidification control unit 30 sets the calculated rotational speed to a second speed R2. On the other hand, if the calculated rotational speed exceeds 4000 rpm, 4000 rpm is set to the second speed R2. It should be noted that after the water atomization operation begins, if the calculated rotational speed is less than 2000 rpm, it is always set to the fourth speed R4 (the speed at which the water-blocking mechanism operates).
