Disclosure of Invention
The conventional liquid micronizing device includes a drain pipe (drain port) connected to the water storage portion for draining water stored in the water storage portion. In the conventional liquid refining apparatus, a gap is formed between a drain pipe (drain port) and a water lifting pipe (water lifting port) by rotation of the water lifting pipe, and water in a water storage portion is suppressed from being discharged from the drain pipe (drain port). That is, the conventional liquid refining apparatus controls the water discharge according to whether the water lifting pipe rotates or not. Therefore, in the conventional liquid reduction apparatus, if the target humidity is repeatedly exceeded and the target humidity is reduced during the humidification operation, the rotation of the water lifting pipe is repeatedly performed and stopped, and as a result, the water in the water storage portion is repeatedly discharged and supplied. That is, in the conventional liquid refining apparatus, when feedback control of the humidification amount during the humidification operation is performed, there is a concern that the amount of water used (the amount of water discharged) increases.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a liquid micronizing device capable of reducing the amount of water (liquid) used when feedback control of the amount of humidification during humidification operation is performed.
The liquid atomizing device of the present invention is a liquid atomizing device which includes an atomized liquid in air sucked from a suction port and blows the atomized liquid out from a blowing port. The liquid micronizing device is characterized by comprising a liquid raising pipe, a collision wall, a storage part and a control part. The liquid-raising pipe is cylindrical, has a liquid-raising port in a lower part in the vertical direction, and discharges liquid drawn by the liquid-raising port in the centrifugal direction with rotation of the rotary shaft. The collision wall refines the liquid by colliding with the liquid discharged from the liquid raising pipe. The storage part is arranged below the vertical direction of the liquid pumping pipe and stores the liquid pumped by the liquid pumping port. The liquid drain port discharges liquid at the bottom surface of the storage portion. The control unit controls the liquid refining operation in the liquid refining apparatus. The suction port communicates with a blower having a humidity recovery unit. In the micronizing operation, the liquid suction pipe rotates at any one of the rotational speeds from the first rotational speed to the second rotational speed greater than the first rotational speed. Any one of the rotational speeds in the range from the first rotational speed to the second rotational speed is the following rotational speed: by rotating the liquid in the storage portion, a vortex is generated in the liquid raising pipe, and a gap communicating between the liquid raising port and the liquid outlet is formed in the center of the vortex, thereby ensuring that the liquid in the storage portion is prevented from flowing into the liquid outlet. When the control unit determines that the humidity of the air sucked from the suction port exceeds the target humidity, the control unit rotates the blower tube at the first rotational speed.
According to the present invention, it is possible to provide a liquid reduction device capable of reducing the amount of liquid used when feedback control of the amount of humidification during humidification operation is performed.

Detailed Description
The liquid atomizing device of the present invention is a liquid atomizing device which is configured to blow air sucked from a suction port while containing atomized water from a blow-out port. The liquid micronizing device comprises a liquid lifting pipe, a collision wall, a storage part and a control part. The liquid-raising pipe is cylindrical, has a liquid-raising port in a lower part in the vertical direction, and discharges liquid drawn by the liquid-raising port in the centrifugal direction with rotation of the rotary shaft. The collision wall refines the liquid discharged from the liquid raising pipe by colliding with the liquid. The storage part is arranged below the vertical direction of the liquid pumping pipe and stores the liquid pumped by the liquid pumping port. The liquid drain port discharges liquid at the bottom surface of the storage portion. The control unit controls the liquid refining operation in the liquid refining apparatus. The suction port communicates with a blower having a humidity recovery unit. In the micronizing operation, the liquid suction pipe rotates at any one of the rotational speeds from the first rotational speed to the second rotational speed greater than the first rotational speed. Any one of the rotational speeds in the range from the first rotational speed to the second rotational speed is the following rotational speed: by rotating the liquid in the storage portion, a vortex is generated in the liquid outlet, and a gap communicating the liquid outlet and the liquid outlet is formed in the center of the vortex, thereby ensuring that the liquid in the storage portion is prevented from flowing into the liquid outlet. When the control unit determines that the humidity of the air sucked from the suction port exceeds the target humidity, the control unit rotates the blower tube at the first rotational speed.
According to this configuration, the control unit rotates the liquid lifting pipe at the first rotational speed even when it is determined that the humidity of the air sucked from the suction port exceeds the target humidity during the humidification operation (the operation of miniaturizing the liquid, in particular, the operation of miniaturizing the water), and therefore, the discharge of the liquid in the reservoir can be suppressed. Therefore, the control unit can prevent the liquid in the reservoir from being discharged even when the humidity exceeds the target humidity and the humidity falls below the target humidity repeatedly, and can reduce the amount of liquid used. That is, when feedback control of the humidification amount during the humidification operation is performed, the liquid reduction device can be realized that can reduce the amount of liquid used.
In the liquid refinement apparatus according to the present invention, the control unit rotates the liquid suction pipe at a third rotation speed in a range from the first rotation speed to the second rotation speed when the humidity of the air sucked from the suction port is lower than the target humidity. In this way, in the feedback control of the humidification amount, the control unit can humidify the necessary humidification amount toward the target humidity when the humidity of the air sucked from the suction port is lower than the target humidity.
In the liquid refinement apparatus according to the present invention, the control unit determines whether or not the humidity of the air sucked from the suction port exceeds the target humidity for each first period. In this way, in the case of performing the feedback control of the humidification amount during the humidification operation, since the adjustment of the humidification amount is performed for each first period, even if the humidity of the air sucked from the suction port suddenly changes for some reason (for example, bathroom use), the adjustment of the humidification amount to the target humidity can be effectively performed.
In the liquid refining apparatus according to the present invention, it is preferable that the control unit stops rotation of the liquid suction pipe when it is determined that the humidity of the air sucked from the suction port exceeds the target humidity for a second period longer than the first period. Thus, when the condition that the air in the room reaches the target humidity continues for the second period, humidification of the air sucked from the suction port is stopped. That is, in the period from stopping humidification to restarting humidification, the amount of liquid used according to the amount of liquid (humidification amount) consumed by humidification due to rotation of the first rotation speed can be reduced.
In the liquid refinement apparatus according to the present invention, it is preferable that the control unit stops rotation of the liquid suction pipe when it is determined that the humidity of the air sucked from the suction port exceeds the target humidity and when the humidity of the air sucked from the suction port becomes the first humidity higher than the target humidity. In this way, the control unit can suppress excessive humidification of the air sucked from the suction port, and thus can control the humidity in the room more appropriately.
In the liquid refining apparatus according to the present invention, the blower is configured to cause the air, the humidity of which is recovered by the humidity recovery unit, to flow into the suction port. In this way, the air after the humidity recovery flows into the liquid micronizing device (suction port), so that the humidity in the room can be controlled more appropriately.
Hereinafter, modes for carrying out the present invention will be described with reference to the drawings. The following embodiments each represent a preferred embodiment of the present disclosure. Accordingly, numerical values, shapes, materials, components, arrangement positions of components, connection modes, and the like shown in the following embodiments are examples, and are not intended to limit the present disclosure. Therefore, among the constituent elements of the following embodiments, constituent elements not described in the independent claims showing the uppermost concept of the present invention will be described as arbitrary constituent elements. In the drawings, substantially the same structures are denoted by the same reference numerals, and repetitive description thereof will be omitted or simplified.
(embodiment 1)
First, a schematic configuration of a liquid refining apparatus 1 according to embodiment 1 of the present invention will be described with reference to fig. 1 and 2. Fig. 1 is a schematic perspective view of a liquid refining apparatus according to embodiment 1 of the present invention. Fig. 2 is a schematic cross-sectional view showing the internal structure of the liquid refinement apparatus according to embodiment 1 of the present invention.
As shown in fig. 1, the liquid reducing device 1 includes a suction port 2 through which air is sucked, and a blowout port 3 through which air sucked through the suction port 2 is blown out. The suction port 2 is provided on a side surface of the liquid refining apparatus 1. The outlet 3 is provided above the liquid refining apparatus 1.
As shown in fig. 2, air passages 4 to 6 are formed in the liquid reducing device 1 from the suction port 2 to the blow-out port 3. The liquid refining apparatus 1 further includes a liquid refining chamber 7 provided in the air passages 4 to 6, and the suction port 2, the liquid refining chamber 7, and the air outlet 3 communicate with each other.
The liquid refining chamber 7 is a main part of the liquid refining apparatus 1, and is a position where water is refined. In the liquid refinement apparatus 1, the air taken in from the intake port 2 is sent to the liquid refinement chamber 7 via the air duct 4. The liquid refining apparatus 1 is configured such that water refined in the liquid refining chamber 7 is contained in the air passing through the air duct 4, and the air containing the water is blown out from the air outlet 3 through the air duct 5 and the air duct 6 in this order. Here, the air duct 5 is configured to change the direction in which the air containing water flows downward in the vertical direction of the liquid refinement chamber 7 from the direction in which the air flows upward in the vertical direction around the air duct. The air duct 6 is configured to directly flow the air passing through the air duct 5 upward in the vertical direction and blow the air out of the air outlet 3.
The liquid refinement chamber 7 is provided with a cylindrical collision wall 8 that opens upward and downward. The collision wall 8 is fixed in the liquid micronization chamber 7. Further, the liquid refinement chamber 7 is provided with a cylindrical water pumping pipe 9 (pumping pipe) that pumps water (pumping water) while rotating inside the collision wall 8. The water pumping pipe 9 has an inverted conical hollow structure, and a circular water pumping port 9a (liquid pumping port) is provided below. The water pipe 9 has a rotation shaft 10 disposed in the vertical direction fixed to the center of the inverted conical top surface above the water pipe 9. The rotation shaft 10 is connected to a rotation motor 11 provided on the outer surface of the liquid refining chamber 7, and the rotation motion of the rotation motor 11 is transmitted to the water pipe 9 through the rotation shaft 10, so that the water pipe 9 rotates. The rotary motor 11 is configured to perform a rotary motion in response to a control signal from a humidification control portion 30 described later.
The water lifting pipe 9 has a plurality of rotating plates 12 formed on the top surface side of the inverted cone shape so as to protrude outward from the outer surface of the water lifting pipe 9. The plurality of rotary plates 12 are formed such that a predetermined interval is provided between vertically adjacent rotary plates 12 in the axial direction of the rotary shaft 10 and protrude outward from the outer surface of the water pipe 9. Since the rotary plate 12 rotates together with the water delivery pipe 9, it is preferable to have a horizontal disk shape coaxial with the rotary shaft 10. The number of the rotary plates 12 is appropriately set according to the target performance or the size of the water lifting pipe 9.
In addition, a plurality of openings 13 penetrating the wall surface of the water pipe 9 are provided on the wall surface of the water pipe 9. The plurality of openings 13 are each provided at a position where the inside of the water pipe 9 communicates with the upper surface of the rotary plate 12 formed so as to protrude outward from the outer surface of the water pipe 9.
A water storage portion 14 (storage portion) for storing water raised by the water raising port 9a of the water raising pipe 9 is provided below the liquid refining chamber 7 in the vertical direction of the water raising pipe 9. The depth of the water reservoir 14 is designed to be immersed in a portion of the lower part of the riser pipe 9, for example a depth of a length of one third to one hundredth of the conical height of the riser pipe 9. The depth can be designed according to the required amount of water to be pumped. The bottom surface of the water storage portion 14 is formed in a mortar shape (bowl shape) inclined downward toward the water lifting port 9a (see fig. 3).
The supply of water to the water storage portion 14 is performed by the water supply portion 15. The water supply portion 15 is connected to a water supply pipe 15a, and water is directly supplied from the water supply pipe 15a through a water pressure adjusting valve (water supply valve: not shown), for example. The water supply portion 15 is provided above the bottom surface of the water storage portion 14 in the vertical direction. The water supply portion 15 is preferably provided not only on the bottom surface of the water storage portion 14 but also above the upper surface of the water storage portion 14 (the surface of the maximum water level that can be stored in the water storage portion 14) in the vertical direction. The water supply unit 15 may be configured to draw a required amount of water from a tank disposed outside the liquid reduction chamber 7 by a siphon principle in advance and supply the water to the water storage unit 14.
The liquid level-reducing device 1 is provided with a water level detection unit 18 for detecting the water level in the water storage unit 14. The water level detection portion 18 has a float switch 18a. The float switch 18a is turned off when the water in the water storage unit 14 does not reach a certain water level (full water state), and is turned on when the water in the water storage unit 14 reaches a certain water level (full water state). That is, the water level detection unit 18 detects whether or not the water in the water storage unit 14 is at a constant water level (full water state) by the float switch 18a. The water level detection unit 18 outputs information on the on or off state of the float switch 18a to the humidification control unit 30. As described below, the humidification control portion 30 controls to supply water from the water supply portion 15 to the water reservoir portion 14 when the float switch 18a is turned off and the off state continues for a predetermined time (first time T1), and controls to stop the supply of water from the water supply portion 15 to the water reservoir portion 14 when the float switch 18a is turned on. Here, the first time T1 is set to a time period in which the water in the water storage unit 14 is not reduced to an amount of water that cannot be raised by the humidification process, and in the present embodiment, is set to a constant time period (for example, 30 minutes).
A drain pipe 16 is connected to the bottom surface of the water storage portion 14. A circular drain port 16a (drain port) provided at a position where the drain pipe 16 is connected is provided at a lowest position of the bottom surface of the water storage portion 14 formed as a mortar. The water blocking and draining of the drain pipe 16 is achieved by the rotation of the water lifting pipe 9. That is, the water blocking mechanism and the water lifting mechanism of the water storage unit 14 are constituted by the water discharge pipe 16 and the water lifting pipe 9. Details of the water blocking mechanism and the water discharging mechanism of the water storage unit 14 composed of the water discharging pipe 16 and the water lifting pipe 9 will be described later with reference to fig. 3.
A cylindrical separator 17 is provided below the collision wall 8 (space between the collision wall 8 and the water storage portion 14), and the separator 17 is disposed so as to be spaced apart from the inside and outside of the liquid micronizing chamber 7, and traps a part of the water droplets to be micronized. The separator 17 is formed of a porous body through which air can flow. The separator 17 is fixed so as to be enclosed in a separator holder 19 connected to the lower portion of the collision wall 8. Specifically, the separator holder 19 is configured to have: the top panel 19c, a first holding portion 19a extending downward in the vertical direction from the top panel 19c, and a second holding portion 19b extending downward in the vertical direction from the top panel 19c at a position further inward (toward the water pipe 9) than the first holding portion 19 a. The separator 17 is sandwiched and fixed by the first holding portion 19a and the second holding portion 19b of the separator holder 19. The second holding portion 19b of the separator holder 19 is connected to the support portion 22 of the water flow control plate 20.
The separator 17 is disposed in the air passage 5, and water droplets in water contained in the air passing through the liquid reduction chamber 7 are collected by flowing through the separator 17. Thus, the air flowing through the air passage 5 contains only the vaporized water.
The water flow control plate 20 is provided above the water storage 14 so as to cover the water storage 14. Specifically, the water flow control plate 20 is formed to have an outer diameter smaller than the diameter of the inner wall of the water storage portion 14, and is disposed so as to cover the upper portion of the water storage portion 14 below the space surrounded by the separator 17. The water flow control plate 20 has a substantially disk-like shape, and an opening (not shown) is formed in the center thereof, the opening being formed so that the water pump pipe 9 can pass through the diameter of the water flow control plate 20. 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), and is fixed to the second holding portion 19b of the separator holder 19 via the support portions 22. The water flow control plate 20 prevents the noise rise caused by the generation of bubbles in the water flow accompanying the rotation of the water pipe 9.
The liquid micronizing device 1 is provided with a humidification control portion 30. The humidification control portion 30 controls the operation of the liquid reduction device 1 to control the humidification operation (the water reduction operation) in the humidification process. The humidification control portion 30 controls a water discharge operation (first process) for discharging water from the water storage portion 14 when the number of times of supplying water to the water storage portion is a predetermined number of times during the humidification operation, and a water discharge operation (second process) for discharging water from the water storage portion when the humidification operation is continued for a predetermined time (second time T2). Here, the second time T2 is a certain time (for example, 24 hours). The humidification control portion 30 controls a drying operation in the drying process performed when the operation of the liquid reduction device 1 is stopped.
The liquid refining apparatus 1 may be configured to control the humidification operation (the water refining operation), the drainage operation (the first process and the second process), and the drying operation by controlling the control unit 60a (see fig. 5) of the heat exchange ventilator 60 without the humidification control unit 30.
Next, the operation principle of humidification (water miniaturization) in the liquid-micronizing device 1 will be described with reference to fig. 2.
First, air supply from the outside (suction of air from the suction port 2) is started. In a state where water is not present in the water storage portion 14, the rotation shaft 10 is rotated at a first rotation speed R1 (for example, 2000 rpm) by the rotation motor 11, and the water lifting pipe 9 is rotated accordingly. Water is supplied from the water supply unit 15 to the water storage unit 14. At this time, in the water storage portion 14, the water supplied to the water storage portion 14 is drawn by the water lifting pipe 9 by the centrifugal force generated by the rotation of the water lifting pipe 9, and the water supplied to the water storage portion 14 is not drained from the drain port 16a and is blocked. As a result, the water supplied from the water supply unit 15 is stored in the water storage unit 14. After the water storage unit 14 is filled with water, the supply of water from the water supply unit 15 to the water storage unit 14 is stopped. The water blocking mechanism and the water draining mechanism will be described later.
Then, when the rotation shaft 10 is rotated at the second rotation speed R2 by the rotation motor 11 and the water pump 9 is rotated accordingly, the water stored in the water storage portion 14 is sucked up by the water pump 9 by the centrifugal force generated by the rotation. Here, the second rotation speed R2 of the rotation motor 11 (the water lifting pipe 9) is set between 2000rpm and 4000rpm according to the amount of humidification of the air. The second rotation speed R2 may be set between 2000rpm and 5000 rpm. Since the water pumping pipe 9 has an inverted conical hollow structure, water pumped by rotation is pumped up along the inner wall of the water pumping pipe 9. The lifted water is discharged from the opening 13 of the water lifting pipe 9 along the rotation plate 12 in the centrifugal direction, and is scattered as water droplets.
The water droplets scattered from the rotating plate 12 are scattered in the space (liquid micronizing chamber 7) surrounded by the collision wall 8, collide with the collision wall 8, and are micronized. On the other hand, the air passing through the liquid-micronizing chamber 7 moves from above the collision wall 8 toward the inside of the collision wall 8, contains water droplets broken (micronized) by the collision wall 8, and moves from below toward the outside of the collision wall 8. And, the air containing the water droplets passes through the separator 17. Thereby, the liquid reducing apparatus 1 can humidify the air sucked from the suction port 2 and blow out the humidified air from the blow-out port 3.
The liquid to be miniaturized may be a liquid other than water, for example, a liquid such as hypochlorous acid water having bactericidal or deodorant properties. By including the hypochlorous acid water to be pulverized in the air sucked from the suction port 2 of the liquid micronizing device 1 and blowing out the air from the air outlet 3, the space where the liquid micronizing device 1 is placed can be sterilized or deodorized.
Next, a water blocking mechanism and a water discharging mechanism of the water storage unit 14 composed of the water discharge pipe 16 and the water lifting pipe 9 will be described in detail with reference to fig. 3. Fig. 3 is a diagram for explaining a water blocking mechanism of a water storage portion constituted by a drain pipe and a water delivery pipe in the liquid reducing apparatus according to embodiment 1 of the present invention.
As shown in fig. 3, in the liquid refining apparatus 1, when the humidifying operation is started and the rotation motor 11 (the water pump pipe 9) rotates at the first rotation speed R1 (for example, 2000 rpm), a vortex 24 is generated in the water storage portion 14 by the centrifugal force of the rotation. The water pump 9 forms a space 25 communicating between the water pump port 9a and the water discharge port 16a at the center of the vortex generated by the rotation. Thus, the void 25 is in a state of blocking the drain port 16a, and the water in the water reservoir 14 is prevented from flowing into the drain port 16a. That is, in the liquid refining apparatus 1, the water in the water reservoir 14 can be suppressed from being discharged from the water discharge port 16a during the humidification operation (during the rotation operation of the rotation motor 11 at the second rotation speed R2). As described above, the water lifting pipe 9 rotates at a rotation speed in a prescribed range (for example, 2000rpm at the minimum and 4000rpm at the maximum). Any rotation speed within the predetermined range is a rotation speed that ensures that the water storage portion 14 is prevented from flowing into the water discharge port 16a.
On the other hand, when the rotation of the rotation motor 11 (the water lifting pipe 9) is stopped, the vortex flow 24 disappears together with the gap 25, and the water in the water storage portion 14 flows into the water discharge port 16a. That is, in the liquid refinement apparatus 1, by stopping the humidification operation (the rotation operation of the rotation motor 11), the water in the water reservoir 14 can be discharged from the water discharge port 16a.
In this way, the liquid reducing device 1 can prevent (block) water in the water storage unit 14 from being discharged from the water discharge port 16a during the humidification operation, even if the water discharge valve is not used in the water discharge pipe 16, and can discharge water in the water storage unit 14 from the water discharge port 16a after the humidification operation is stopped.
Next, a heat exchange ventilator 60 including the liquid micronizing device 1 according to embodiment 1 will be described with reference to fig. 4. Fig. 4 is a schematic perspective view of a heat exchange ventilator including a liquid micronizing device 60 according to embodiment 1.
As shown in fig. 4, the heat exchange ventilator 60 is configured to include a liquid micronizing device 1, a humidity recovery unit 65, and a blower 67. The heat exchange ventilator 60 blows outside air (air whose humidity has been recovered by the humidity recovery unit 65) sucked from the outside air suction port 63 to the suction port 2 (see fig. 1) of the liquid micronizing device 1 through the connection duct 66. The liquid reducing device 1 humidifies air sucked from the suction port 2, blows the humidified air out from the blowout port 3 (see fig. 1), and supplies the humidified air into the room through the air supply port 64. Here, the heat exchange ventilator 60 corresponds to a "blower" according to the present invention.
The heat exchange ventilator 60 has a box-shaped main body case 50, and is used in a state of being placed on a floor, for example. An internal air inlet 61, an exhaust port 62, an external air inlet 63, and an air supply port 64 are provided on the top surface of the main body case 50 (the surface on which the liquid reduction device 1 is mounted). Further, a liquid micronizing device 1 is provided on the top surface of the main body case 50. A humidity recovery unit 65 and an air blower 67 are provided in the main body case 50.
The interior air intake port 61 is an intake port for taking in air (interior air) in the building into the heat exchange ventilator 60. Specifically, the internal gas inlet 61 is connected to the indoor exhaust port through a duct (not shown) extending to the ceiling surface or wall surface of each space in the building so as to communicate with the indoor exhaust port through which the internal gas is sucked.
The exhaust port 62 is an exhaust port for supplying the internal air from the heat exchange ventilator 60 to the outside. Specifically, the exhaust port 62 is connected to an outdoor exhaust port that blows out the internal gas through a duct (not shown) extending to the outer wall surface of the building.
The outside air intake port 63 is an intake port for taking in air (outside air) outside the building into the heat exchange ventilator 60. Specifically, the outdoor air intake port 63 is connected to an outdoor air supply port through a duct (not shown) extending to the outer wall surface of the building so as to communicate with the outdoor air supply port through which the outdoor air is taken in.
The air supply port 64 is a discharge port for supplying the outside air from the heat exchange ventilator 60 into the room via the liquid micronizer 1. Specifically, the air supply port 64 is connected to an indoor air supply port through a duct (not shown) extending to the ceiling surface or wall surface of each space in the building so as to blow out outside air.
The humidity recovery unit 65 is provided in the main body case 50 at a position upstream of the blower 67. The humidity recovery unit 65 has a function of recovering (exchanging) humidity of air sucked by the operation of the blower 67 and passing through the inside (particularly, the supply air passage) of the heat exchange ventilator 60. The humidity recovery unit 65 is, for example, a desiccant type or a heat pump type heat exchanger.
The air supply duct is not particularly shown, and is a duct for sucking fresh air (outside air) from the outside air suction port 63, and supplying the fresh air to the room from the air supply port 64 by passing through the humidity recovery unit 65, the blower 67, the connection duct 66, and the liquid refining apparatus 1 in this order.
The connection duct 66 is a duct that connects and communicates the blower 67 with the suction port 2. The connection duct 66 is provided with a temperature and humidity sensor 34 on the suction port 2 side of the connection duct 66. The temperature and humidity sensor 34 is a sensor that detects the temperature and humidity of air (air sucked into the suction port 2) flowing through the supply air duct.
The blower 67 is a device for blowing outside air from the outside air intake port 63 to the air supply port 64. The blower 67 circulates outside air inside the humidity recovery unit 65 by blowing. Examples of the blower 67 include a cross flow fan (cross flow fan) and a blower fan (blower fan). The blower 67 is configured to perform a blower operation based on a control signal from a control unit 60a (see fig. 5) that controls the heat exchange ventilator 60.
The heat exchange ventilator 60 is provided with a water supply and drainage pipe 51. The water is supplied to and discharged from the liquid refining apparatus 1 through the water supply and discharge pipe 51. Specifically, one end of the water supply and drainage pipe 51 is connected to the water supply pipe 15a (see fig. 2) and the water drainage pipe 16 (see fig. 2) of the liquid micronizing device 1. The other end of the water supply/drainage pipe 51 is connected to a water supply facility and a drainage facility of a house or facility, respectively.
The heat exchange ventilator 60 further includes a control unit 60a (see fig. 5) that controls the air blowing operation of the blower 67. The control unit 60a is electrically connected to the humidification control unit 30 of the liquid reduction device 1, and receives a control signal from the humidification control unit 30 to control the blower 67 and the liquid reduction device 1 in a linked manner.
As described above, in the heat exchange ventilator 60, when the air is ventilated, the moisture discharged to the outside is recovered in the air supplied to the room, and when the moisture recovery unit 65 does not completely recover the moisture, the moisture can be filled or added to the air when the air is passed through the liquid micronizing device 1, and therefore the room can be maintained in the humidifying and comfortable humidity range.
Next, the humidification control portion 30 of the liquid reduction device 1 will be described with reference to fig. 5. Fig. 5 is a block diagram showing the configuration of a humidification control portion in the liquid refinement apparatus according to embodiment 1 of the present invention.
As shown in fig. 5, the humidification control portion 30 includes: an input unit 30a, a storage unit 30b, a timer unit 30c, a processing unit 30d, and an output unit 30e.
The input unit 30a receives first information related to an operation start instruction or an operation stop instruction 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 (air sucked into the suction port 2) before humidification from the temperature and humidity sensor 34, and fifth information related to the on or off 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.
Here, the operation panel 31 is a terminal for inputting user input information (for example, an air volume, a humidification amount, a blowout temperature, and the like) related to the liquid level reducing device 1 and the heat exchange ventilation device 60, and is communicably connected to the humidification control portion 30 by wireless or wired connection. It should be noted that the first information further includes user input information. The temperature and humidity sensor 32 is a sensor that senses the temperature and humidity of the indoor air immediately after the intake from the internal air intake port 61. The temperature sensor 33 is a sensor that senses the temperature of the outdoor air immediately after the intake of the outdoor air from the outdoor air intake port 63.
The storage unit 30b stores sixth information related to humidification setting during humidification operation, seventh information related to drainage setting during drainage operation (first process, second process), eighth information related to drying setting during drying operation, 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.
The timer unit 30c outputs tenth information related to the current time to the processing unit 30d.
The processing unit 30d receives the first to fifth information from the input unit 30a, the sixth to ninth information from the storage unit 30b, and the tenth information from the timer unit 30 c. The processing unit 30d uses the received first to tenth information to determine control information related to the humidification operation set by humidification, the drainage operation set by drainage (first and second processes), and the drying operation in the drying setting. The processing unit 30d outputs the determined control information to the output unit 30e.
The output unit 30e receives control information from the processing unit 30 d. The output unit 30e is electrically connected to the heat exchange ventilator 60 (the control unit 60a and the blower 67), the rotary motor 11, and the water supply valve 15 b. The output unit 30e outputs signals (control signals) for controlling the blowing operation of the blower 67, the humidification operation (rotation operation of the rotation motor 11) in the liquid refinement chamber 7, and the opening and closing operation of the water supply valve 15b, based on the received control information.
The heat exchange ventilator 60 (control unit 60a, blower 67) receives a signal from the output unit 30e, and the control unit 60a executes control of the blower 67 based on the received signal. The rotary motor 11 and the water supply valve 15b receive signals from the output unit 30e, respectively, and perform control based on the received signals.
As described above, the humidification control portion 30 performs control of the humidification operation in the humidification process, control of the drainage operation in the first process or the second process, and control of the drying operation in the drying process, respectively.
Next, with reference to fig. 6 to 10, a description will be given of a processing procedure in the humidifying operation of the liquid atomizing device 1. Fig. 6 and 7 are flowcharts showing a humidification processing procedure of the liquid reduction device according to embodiment 1 of the present invention. Fig. 8 is a flowchart showing a water supply processing step of the liquid refining apparatus according to embodiment 1 of the present invention. Fig. 9 is a flowchart showing a water micronization process procedure of the liquid micronization device according to embodiment 1 of the present invention. Fig. 10 is a flowchart showing a drainage treatment step of the liquid refining apparatus according to embodiment 1 of the present invention. Hereinafter, the case where the blower 67 performs the blower operation not based on the control signal from the control unit 60a but based on the control signal from the humidification control unit 30 will be described.
When a control signal related to the start of the humidification processing operation of the liquid level-reducing apparatus 1 is input to the humidification control portion 30, as shown in fig. 6, first, the humidification control portion 30 operates the blower 67 to start the blowing of air from the blower 67 (step S01). Thereby, air flows through the liquid refining apparatus 1 (liquid refining chamber 7). Then, the humidification control portion 30 resets the water level detection counter N to "0" (step S02). Here, the water level detection counter N is a value showing 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 fully filled with water). The humidification control portion 30 also performs water supply processing for supplying water to the water storage portion 14 (step S03).
In the water supply process, as shown in fig. 8, the humidification control portion 30 operates the rotary motor 11 at a first rotational speed R1 (for example, 2000 rpm) to bring the water blocking mechanism into a state of functioning (step S20). Next, the humidification control portion 30 opens the water supply valve 15b of the water supply portion 15 to start the supply of water to the water reservoir portion 14 (step S21). The humidification control portion 30 determines whether or not the water level in the water storage portion 14 is full of water based on the fifth information from the water level detection portion 18 (step S22). As a result, when the water in the water storage unit 14 is not in the full water state (no in step S22), the humidification control portion 30 continues to supply water to the water storage unit 14 (returns to step S22). On the other hand, when the water in the water storage unit 14 is full (yes in step S22), the humidification control portion 30 closes the water supply valve 15b to stop the supply of water to the water storage unit 14 (step S23). The humidification control portion 30 adds "1" to the water level detection counter N (step S24). Through the above steps, the water supply process for supplying water to the water storage portion 14 is completed. However, the water supply process is ended in a state where the rotary motor 11 is rotated at the first rotation speed R1. Returning to fig. 6.
When the water supply process (step S03) for supplying water to the water storage unit 14 is completed, the humidification control portion 30 executes the water micronization process (step S04) as a humidification operation in the humidification process.
In the water micronization process, as shown in fig. 9, the humidification control portion 30 determines whether humidification (water micronization) is necessary 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, when humidification is necessary (yes in step S30), the humidification control portion 30 rotates the rotation motor 11 at the second rotation speed R2, and starts a humidification operation (water micronization operation) based on humidification setting (step S31). Here, the second rotation speed R2 is a rotation speed determined by a humidification condition (for example, a humidification amount to a target humidity), and is set to at least the first rotation speed R1 or more. Then, it is determined whether or not a predetermined time (fifth time T5) has elapsed from the time of operation of the rotary motor 11 in step S31 as the start time (step S32). As a result, if the fifth time T5 has not elapsed (no in step S32), the humidification control portion 30 continues the water reduction operation (return to step S32). On the other hand, when the fifth time T5 has elapsed (yes in step S32), the humidification control portion 30 proceeds to the next step while continuing the water reduction operation (step S05). Here, the fifth time T5 is an interval time of feedback control for humidification, and is set to 5 minutes, for example.
On the other hand, when it is determined in step S30 that humidification is not necessary (no in step S30), the humidification control portion 30 causes the rotation motor 11 to operate at the fourth rotation speed R4 (for example, 2000 rpm) and at least the water blocking mechanism is in a state of functioning (step S33). When the rotation motor 11 has rotated at the fourth rotation speed R4, the fourth rotation speed R4 is maintained. Then, it is determined whether or not a predetermined time (sixth time T6) has elapsed from the time when the rotation motor 11 is operated or the operation maintaining time is counted as the start time in step S33 (step S34). As a result, if the sixth time T6 has not elapsed (no in step S34), the humidification control portion 30 continues the water blocking state (returns to step S34). On the other hand, when the sixth time T6 has elapsed (yes in step S34), the humidification control portion 30 proceeds to the next step (step S35). Here, the sixth time T6 is an interval time of feedback control for humidification, and is set to 5 minutes, for example. The fifth time T5 (more precisely, the time obtained by adding the time required for the water supply in step S06 to the fifth time T5) or the sixth time T6 corresponds to the "first period" of the present invention.
Next, a determination is made as to whether or not the predetermined time (seventh time T7) has elapsed from the time of operation of the rotary motor 11 in step S33 as the start time (step S35). As a result, when the seventh time T7 has not elapsed (no in step S35), the humidification control portion 30 returns to step S30 in a state where the rotation motor 11 is rotated at the fourth rotation speed R4, and again makes a determination as to whether humidification is necessary. On the other hand, when the seventh time T7 has elapsed (yes in step S35), the humidification control portion 30 stops the rotation motor 11 (step S36). Then, the humidification control portion 30 returns to step S02, and resumes the operation of the humidification processing of the liquid micronization device 1. Here, the seventh time T7 is set to 2 hours, for example. The seventh time T7 corresponds to the "second period" of the present invention. Returning to fig. 6.
When the water micronization process (step S04) is completed, a determination is made as to whether or not a predetermined time (first time T1) has elapsed from the time of operation of the rotary motor 11 in step S31 as the start time, while continuing the water micronization operation (step S05). As a result, when the first time T1 has elapsed (yes in step S05), the humidification control portion 30 performs water supply processing for supplying water to the water reservoir portion 14 (see fig. 8), and sets the water reservoir portion 14 to a full state (step S06). On the other hand, when the first time T1 has not elapsed (no in step S05), the humidification control portion 30 continues the water micronization operation (return to step S05). Here, the first time T1 is set to a time set to, for example, 30 minutes, in which a decrease in the amount of water in the water storage portion 14 due to the humidification operation is expected to decrease.
Next, when a predetermined time (second time T2) from step S02 has elapsed (yes in step S07), humidification control portion 30 executes the processing of step S10 (see fig. 7) and steps S10 and subsequent steps. Here, the second time T2 is a time counted by taking the reset time of the water level detection counter N in step S02 as the start time, and is set to 24 hours, for example. The second time T2 may be a time after the start of the liquid reducing apparatus 1 or a time after the last drying operation. On the other hand, when the second time T2 has not elapsed (no in step S07), the humidification control portion 30 determines whether or not the number of times of water supply in the full water state exceeds M times (for example, 10 times) based on the water level detection counter N (step S08). As a result, if the water level detection counter N does not exceed M times (no in step S08), the flow returns to step S04, and the humidification control portion 30 repeatedly executes the humidification operation. On the other hand, when the water level detection counter N exceeds M times (yes in step S08), the humidification control portion 30 performs the water discharge process of the water in the water reservoir portion 14 (step S09). Here, the processing in step S08 and step S09 is a drainage operation corresponding to the first processing.
In the water discharge process, as shown in fig. 10, the humidification control portion 30 stops the rotation motor 11, and the water blocking mechanism is not activated (step S40). Thereby, the water in the water storage portion 14 starts to be discharged. Then, a judgment is made as to whether or not the predetermined time (eighth time T8) has elapsed from the stop time of the rotary motor 11 in step S40 as the start time (step S41). As a result, if the eighth time T8 has not elapsed (no in step S41), the humidification control portion 30 continues the water discharge state (returns to step S41). On the other hand, when the eighth time T8 has elapsed (yes in step S41), the humidification control portion 30 considers that the water in the water reservoir portion 14 is discharged, and terminates the water discharge process of the water in the water reservoir portion 14. Here, the eighth time T8 is a time when the water in the water storage unit 14 is reliably discharged (a time when the water is discharged even in a full state), and is set to 1 minute, for example. Returning to fig. 6.
When the water drainage process of the water storage unit 14 is completed (step S09), the humidification control portion 30 returns to step S02, and the steps are repeatedly executed.
Next, with reference to fig. 7, the processing performed in step S10 and steps S10 and subsequent steps performed when the second time T2 has elapsed will be described.
When the second time T2 has elapsed (yes in step S07), the humidification control portion 30 performs water discharge processing of the water in the water storage portion 14 (see fig. 10) as shown in fig. 7 (step S10). Here, the processing in step S07 and step S10 is a drainage operation corresponding to the second processing. When the water drainage process of the water storage unit 14 is completed (step S10), the humidification control portion 30 rotates the rotation motor 11 at the third rotation speed R3 (for example, 2000 rpm) to start the first drying operation (the operation of miniaturizing the water storage unit 14 in a state where water is not present) (step S11). When a predetermined time (third time T3) has elapsed since the start of the first drying operation (yes in step S12), humidification control portion 30 stops rotary motor 11 (step S13). On the other hand, if the third time T3 has not elapsed (no in step S12), the humidification control portion 30 continues the first drying operation (returns to step S12). That is, in the first drying operation, the water pump 9 is rotated in a state where there is no water in the water storage portion 14, and the water droplets remaining by adhering to the water pump 9 or the like are removed. The third time T3 is a time for removing water droplets based on the rotation of the water pipe 9, and is set to 30 seconds, for example.
When the first drying operation is completed, the second drying operation is performed in which air flows through the liquid refining apparatus 1 (liquid refining chamber 7) in a state where the refining operation is stopped. When the predetermined time (fourth time T4) has not elapsed since the start of the second drying operation (no in step S14), the humidification control portion 30 continues the second drying operation (returns to step S14). That is, in the second drying operation, the ventilation operation into the liquid refining apparatus 1 (liquid refining chamber 7) is performed, and drying (removal of moisture remaining in the apparatus) in the apparatus is completed. The fourth time T4 is a drying time based on ventilation in the apparatus, and is set to 1 hour, for example. On the other hand, when the fourth time T4 has elapsed (yes in step S14), the humidification control portion 30 determines whether or not a control signal relating to the operation stop of the humidification processing of the liquid level-reducing device 1 has been input (step S15). As a result, when the control signal related to the operation stop of the humidification processing is not input (no in step S15), the humidification control portion 30 returns to step S02, and the operation of the humidification processing of the liquid mill 1 is restarted. On the other hand, when a control signal related to the operation stop of the humidification processing is input (yes in step S15), the humidification control portion 30 stops the blower 67 (step S16). The humidification control portion 30 ends the operation of the humidification processing of the liquid reduction device 1. Thus, the liquid reducing apparatus 1 is in a state of waiting for an operation start instruction from the operation panel 31.
Here, the processing in the first drying operation (step S11 to step S13) and the second drying operation (step S13 to step S14) is a drying operation.
The first rotational speed R1, the second rotational speed R2 (the minimum 2000rpm in the rotational speed range), the third rotational speed R3, and the fourth rotational speed R4 correspond to the "first rotational speed" of the present invention. The second rotational speed R2 (4000 rpm maximum in the rotational speed range) corresponds to the "second rotational speed" of the solution. The second rotational speed R2 (rotational speed in the range of 2000rpm to 4000 rpm) corresponds to the "third rotational speed" of the solution.
As described above, each process in the humidification operation of the liquid level-reducing device 1 is performed in the heat exchange ventilator 60.
As described above, according to the liquid reducing apparatus 1 of embodiment 1, the following effects can be obtained.
(1) In the liquid refining apparatus 1, when it is determined that the humidity of the air sucked from the suction port 2 exceeds the target humidity (the amount of humidification to the target humidity), the humidification control portion 30 controls the water lifting pipe 9 to rotate at the fourth rotation speed R4 (2000 rpm). Thus, in the liquid reducing device 1, even when it is determined that the humidity of the air sucked from the suction port 2 exceeds the target humidity during the humidification operation (the water reducing operation), the water supply pipe 9 is rotated at the fourth rotation speed R4, and the water in the water storage portion 14 can be suppressed from being discharged. Therefore, the liquid reducing device 1 can reliably block water in the water storage portion 14 and reduce the discharge amount of water even when the humidity exceeds the target humidity and the humidity falls below the target humidity repeatedly. That is, when feedback control of the humidification amount during the humidification operation is performed, the liquid reduction apparatus 1 capable of reducing the amount of water used can be provided.
(2) In the liquid refining apparatus 1, the humidification control portion 30 controls the water lifting pipe 9 to rotate at the second rotation speed R2 (2000 rpm to 4000 rpm) when the humidity of the air sucked from the suction port 2 is less than the target humidity. In this way, in the feedback control of the humidification amount, the liquid reduction device 1 can humidify the target humidity by the necessary humidification amount when the humidity of the air sucked from the suction port 2 is lower than the target humidity.
(3) In the liquid refining apparatus 1, the humidification control portion 30 performs control so as to determine whether or not the humidity of the air sucked from the suction port 2 exceeds the target humidity for each predetermined period (the fifth time T5 or the sixth time T6). In this way, when the feedback control of the humidification amount during the humidification operation is performed, the adjustment of the humidification amount is performed for each predetermined period, and therefore, even if the humidity of the air sucked from the suction port 2 changes sharply for some reason (for example, bathroom use), the adjustment of the humidification amount to the target humidity can be performed effectively.
(4) In the liquid refining apparatus 1, the humidification control portion 30 controls the rotation of the water lifting pipe 9 (the rotation motor 11) to stop when it is determined that the humidity of the air sucked from the suction port 2 exceeds the target humidity for the seventh time T7. Thus, when the condition in which the indoor air reaches the target humidity continues for the seventh time T7, humidification of the air sucked from the suction port 2 is stopped. That is, the amount of water used in accordance with the amount of water (humidification amount) consumed by humidification due to rotation of the fourth rotation speed R4 (2000 rpm) can be reduced from the stop of humidification to the restart of humidification.
(5) In the heat exchange ventilator 60, the humidity recovery unit 65 is disposed upstream of the liquid micronizing device 1 in the flow of air passing through the liquid micronizing device 1 and the humidity recovery unit 65. That is, in the liquid micronizing device 1, the humidity recovery unit 65 is arranged such that the air in which the humidity is recovered by the humidity recovery unit 65 flows into the suction port 2. Accordingly, the air after humidity recovery by the humidity recovery unit 65 flows into the liquid micronizing device 1 (suction port 2), and thus the humidity in the room can be controlled more appropriately. Further, by performing humidity control at both the humidity recovery unit 65 and the liquid reduction device 1, a sufficient amount of humidification can be ensured even when a heater or the like is not provided in the humidity recovery unit 65 or the liquid reduction device 1. In addition, by eliminating the need for a heater for ensuring the humidification amount, energy saving can be achieved.
(6) The liquid refining apparatus 1 is configured to execute a first process of discharging water in the water storage portion 14 when the number of times of supplying water to the water storage portion 14 reaches a predetermined number (more than M times) in a humidification operation (a refining operation). In the first treatment, since the water in the water storage portion 14 is discharged every predetermined number of times by the number of times of supplying the water to the water storage portion 14, the amount of water used can be reduced as compared with the case of discharging water each time. The prescribed number of times is a number of times of two or more.
(7) In the liquid refining apparatus 1, in the humidification operation (the refining operation), when the number of times of supplying water to the water storage portion 14 reaches a predetermined number of times (more than M times), the first process of discharging the water in the water storage portion 14 is performed. Thus, when the number of times of supplying water to the water storage 14 during the humidification operation reaches a predetermined number of times (more than M times), the water in the water storage 14 (water in which scale components such as calcium components and magnesium components are concentrated) is discharged and removed by the execution of the first treatment. Therefore, the increase in the concentration of scale components in the water storage unit 14 can be suppressed.
(8) In the liquid refining apparatus 1, when the humidification operation (the refining operation) is continued for a predetermined time (the second time T2), the second process of discharging the water in the water storage portion 14 is performed. Thus, even when the humidification operation is continued for a predetermined time (second time T2), the water in the water storage portion 14 (water in which the scale components are concentrated) is discharged and removed by performing the second treatment. That is, in the liquid refining apparatus 1, the increase in the concentration of scale components in the water storage portion 14 can be reliably suppressed by the first treatment or the second treatment.
(9) In the liquid refining apparatus 1, after the second process is completed, the humidification operation (the refining operation) is performed in a state where there is no water in the water storage portion 14, and the drying process of blowing air from the blower 67 is performed. Thus, since the inside of the apparatus can be dried, the propagation of mold, bacteria, and the like in the apparatus can be suppressed while maintaining the stopped state of the liquid refinement apparatus 1 for a long period of time.
(embodiment 2)
Conventionally, there is a liquid micronizing device that refines water and blows out air that is sucked into the device while containing the water (for example, patent literature 2). In such a conventional liquid refinement apparatus, a liquid refinement chamber for refining water is provided in an air passage between a suction air inlet and a blowout outlet for blowing out sucked air. The liquid micronizing chamber includes a water lifting pipe fixed to a rotation shaft of the rotation motor. The water stored in the water storage part is supplied to the water pumping pipe to pump water by rotating the water pumping pipe through the rotating motor, and the pumped water is radiated to the centrifugal direction. The water emitted from the porous portion is made to pass through the porous portion, thereby making the water finer. In addition, in the conventional liquid refinement apparatus, the water level in the water storage portion is detected during operation, and the automatic water supply valve is controlled to maintain the water level in the water storage portion at a predetermined level.
However, in the conventional liquid refinement apparatus described in patent document 2, if the humidifying operation is continuously performed while the water is automatically supplied, only water in the water storage portion is gasified, and scale components such as calcium components and magnesium components contained in the water supplied in proportion to the use time and the amount of water used are concentrated. As a result, scale components contained in the lifted water are precipitated in the porous portion, and the porous portion may be clogged. Further, such clogging may occur in a liquid refining apparatus including a separator for capturing water droplets in water contained in air passing through the liquid refining chamber.
The present embodiment has been made to solve the above-described problems, and provides a liquid micronizing device capable of suppressing occurrence of clogging in the device when the device is used continuously for a long period of time.
The liquid atomizing device according to the present embodiment is a liquid atomizing device that includes an atomized liquid in air taken in from a suction port and blows the atomized liquid out from a blowing port. The liquid micronizing device comprises: a tubular liquid-raising pipe having a liquid-raising port in a lower part in a vertical direction, the liquid being sucked from the liquid-raising port and discharged in a centrifugal direction in response to rotation of the rotary shaft; a collision wall that refines the liquid discharged from the liquid raising pipe by colliding with the liquid; a storage unit which is provided below the liquid suction pipe in the vertical direction and stores liquid drawn by the liquid suction pipe; a separator provided between the collision wall and the reservoir portion, for capturing a part of the droplets to be miniaturized; and a control unit that controls the operation of miniaturizing the liquid in the liquid miniaturizing device. The suction port communicates with an air blower having a humidity recovery unit. The control unit executes a first process of discharging the liquid from the reservoir unit when the number of times of supply of the liquid to the reservoir unit reaches a predetermined number of times during the micronization operation.
According to this configuration, when the number of times of supplying the liquid to the reservoir portion reaches a predetermined number of times during the micronization operation, the liquid (for example, water in a state where the scale component is concentrated) in the reservoir portion is discharged and removed by the execution of the first process. Therefore, the increase in the concentration of scale components in the liquid in the reservoir can be suppressed. As a result, the scale component contained in the liquid in the reservoir can be reduced from entering the separator during the subsequent micronization operation. That is, when the device is used continuously for a long period of time, the device can be made into a liquid refinement device capable of suppressing occurrence of clogging in the device.
In the liquid refinement apparatus according to the present embodiment, it is preferable that the control unit executes the second process of discharging the liquid in the reservoir unit when the refinement operation is continued for a predetermined period (second time). In this way, even when the micronization operation is continued for the second time, the liquid (for example, water in which the scale component is concentrated) in the reservoir can be discharged and removed by performing the second process. That is, the first treatment or the second treatment can reliably suppress the increase in the concentration of the scale component in the liquid in the reservoir.
In the liquid refining apparatus according to the present invention, it is preferable that the control unit performs the third process of performing the air blowing from the air blowing device while performing the refining operation in a state where the liquid is not present in the storage unit after the second process is completed. In this way, since the inside of the apparatus can be dried after the completion of the third process, the propagation of mold, foreign bacteria, and the like in the apparatus can be suppressed while maintaining the stopped state of the liquid reduction apparatus for a long period of time.
In the liquid refinement apparatus according to the present invention, the liquid outlet is provided to discharge the liquid at the bottom surface of the storage portion, and the liquid in the storage portion is swirled by the rotation in the liquid suction pipe during the refinement operation, a space communicating between the liquid suction port and the liquid outlet is formed at the center of the swirl, and the liquid in the storage portion is prevented from flowing to the liquid outlet. In this way, the liquid can be stored and discharged in the liquid reduction device without using a drain valve. Therefore, since the opening area of the drain port can be increased or the inner diameter of the drain pipe can be made thicker, the liquid reduction device can be made less likely to cause clogging by the drain mechanism.
The liquid refinement apparatus 1 of the present embodiment is identical in structure to the liquid refinement apparatus 1 of embodiment 1. However, the liquid crystal device 1 of the present embodiment may not include the temperature and humidity sensor 34.
The processing steps in the humidifying operation of the liquid crystal device 1 will be described with reference to fig. 11 to 14. Fig. 11 and 12 are flowcharts showing a humidification processing procedure of the liquid reduction device according to embodiment 2 of the present invention. Fig. 13 is a flowchart showing a water supply processing step of the liquid refining apparatus according to embodiment 2 of the present invention. Fig. 14 is a flowchart showing a drainage treatment procedure of the liquid refining apparatus according to embodiment 2 of the present invention. Hereinafter, the case where the blower 67 performs the blower operation not based on the control signal from the control unit 60a but based on the control signal from the humidification control unit 30 will be described.
As shown in fig. 11, when a control signal related to the start of the humidification processing of the liquid level-reducing apparatus 1 is input to the humidification control portion 30, the humidification control portion 30 first operates the blower 67 to start the air blowing from the blower 67 (step S51). Thereby, air flows through the liquid refining apparatus 1 (liquid refining chamber 7). The humidification control portion 30 resets the water level detection counter N to "0" (step S52). Here, the water level detection counter N is a value indicating 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 fully filled with water). The humidification control portion 30 also performs water supply processing for supplying water to the water storage portion 14 (step S53).
In the water supply process, as shown in fig. 13, the humidification control portion 30 operates the rotary motor 11 at a first rotational speed R1 (for example, 2000 rpm) to bring the water blocking mechanism into a state of functioning (step S70). Next, the humidification control portion 30 opens the water supply valve 15b of the water supply portion 15 to start the supply of water to the water reservoir portion 14 (step S71). The humidification control portion 30 determines whether or not the water level in the water storage portion 14 is full based on fifth information on the on or off state of the float switch 18a from the water level detection portion 18 (step S72). As a result, when the water in the water storage unit 14 is not in the full water state (no in step S72), the humidification control portion 30 continues to supply water to the water storage unit 14 (return to step S72). On the other hand, when the water in the water storage unit 14 is full (yes in step S72), the humidification control portion 30 closes the water supply valve 15b to stop the supply of water to the water storage unit 14 (step S73). The humidification control portion 30 adds "1" to the water level detection counter N (step S74). Through the above steps, the water supply process for supplying water to the water storage portion 14 is completed. However, the water supply process is ended in a state where the rotary motor 11 is rotated at the first rotation speed R1. Returning to fig. 11.
When the water supply process (step S53) for supplying water to the water storage unit 14 is completed, the humidification control portion 30 rotates the rotation motor 11 at the second rotation speed R2, and starts the humidification operation (humidification operation) based on the humidification setting (step S54). Here, the second rotation speed R2 is a rotation speed determined by a humidification condition (for example, a humidification amount), and is set to be at least the first rotation speed R1 or more. When a predetermined time (first time T1) from step S54 is elapsed during the humidification operation (yes in step S55), the humidification control portion 30 performs a water supply process (see fig. 13) for supplying water to the water reservoir portion 14, and sets the water reservoir portion 14 to a full state (step S56). On the other hand, when the first time T1 has not elapsed (no in step S55), the humidification control portion 30 continues the humidification operation (returns to step S55). Here, the first time T1 is a time counted by taking the operation time of the rotary motor 11 in step S54 as a start time, and is set to 30 minutes, for example.
Next, when a predetermined time (second time T2) from step S52 has elapsed (yes in step S57), humidification control portion 30 executes the processing of step S60 (see fig. 12) and steps S60 and subsequent steps. Here, the second time T2 is a time counted by taking the reset time of the water level detection counter N in step S52 as the start time, and is set to 24 hours, for example. The second time T2 may be a time after the start of the liquid reducing apparatus 1 or a time after the last drying operation. On the other hand, when the second time T2 has not elapsed (no in step S57), the humidification control portion 30 determines whether or not the number of times of water supply in the full water state exceeds M times (for example, 10 times) based on the water level detection counter N (step S58). As a result, if the water level detection counter N does not exceed M times (no in step S58), the flow returns to step S54, and the humidification control portion 30 repeatedly executes the humidification operation. On the other hand, when the water level detection counter N exceeds M times (yes in step S58), the humidification control portion 30 performs the water discharge process of the water in the water reservoir portion 14 (step S59). Here, the processing in step S58 and step S59 is a drainage operation corresponding to the first processing.
In the water discharge process, as shown in fig. 14, the humidification control portion 30 stops the rotation motor 11, and the water blocking mechanism is not activated (step S80). Thereby, the water in the water storage portion 14 starts to be discharged. When the predetermined time (eighth time T8) from step S80 does not elapse during the water discharge (no in step S81), humidification control portion 30 continues the water discharge state (returns to step S81). On the other hand, when the eighth time T8 has elapsed (yes in step S81), the humidification control portion 30 considers that the water in the water reservoir portion 14 is discharged, and terminates the water discharge process of the water in the water reservoir portion 14. Here, the eighth time T8 is a time counted by taking the stop time of the rotary motor 11 in step S80 as the start time, and is set to 1 minute, for example. Returning to fig. 11.
When the water drainage process of the water storage unit 14 is completed (step S59), the humidification control portion 30 returns to step S52, and the steps are repeatedly executed.
Next, with reference to fig. 12, the processing performed in step S60 and steps S60 and subsequent steps performed when the second time T2 has elapsed will be described.
When the second time T2 has elapsed (yes in step S57), the humidification control portion 30 performs water discharge processing of the water in the water storage portion 14 (see fig. 14) as shown in fig. 12 (step S60). Here, the processing in step S57 and step S60 is a drainage operation corresponding to the second processing. When the water drainage process of the water storage unit 14 is completed (step S60), the humidification control portion 30 rotates the rotary motor 11 at the third rotation speed R3 (for example, 2000 rpm) to start the first drying operation (the operation of miniaturizing the water storage unit 14 in a state where no water is present) (step S61). When a predetermined time (third time T3) has elapsed after the first drying operation is started (yes in step S62), humidification control portion 30 stops rotary motor 11 (step S63). On the other hand, if the third time T3 has not elapsed (no in step S62), the humidification control portion 30 continues the first drying operation (returns to step S62). That is, in the first drying operation, the water pump 9 is rotated in a state where there is no water in the water storage portion 14, and the water droplets remaining on the water pump 9 or the like are removed. The third time T3 is set to, for example, 30 seconds.
When the first drying operation is completed, the second drying operation is performed in which air flows through the liquid refining apparatus 1 (liquid refining chamber 7) in a state where the refining operation is stopped. When the predetermined time (fourth time T4) has not elapsed since the start of the second drying operation (no in step S64), the humidification control portion 30 continues the second drying operation (returns to step S64). That is, in the second drying operation, the ventilation operation into the liquid refining apparatus 1 (liquid refining chamber 7) is performed, and the drying (removal of the moisture remaining in the apparatus) is performed in the apparatus. The fourth time T4 is set to, for example, 1 hour. On the other hand, when the fourth time T4 has elapsed (yes in step S64), the humidification control portion 30 determines whether or not a control signal relating to the operation stop of the humidification processing of the liquid level-reducing device 1 has been input (step S65). As a result, when the control signal related to the operation stop of the humidification processing is not input (no in step S65), the humidification control portion 30 returns to step S52, and the operation of the humidification processing of the liquid mill 1 is restarted. On the other hand, when the operation stop related control signal of the humidification processing is input (yes in step S65), the humidification control portion 30 stops the blower 67 (step S66). The humidification control portion 30 ends the operation of the humidification processing of the liquid reduction device 1. Thereby, the liquid reducing apparatus 1 is in a state of waiting for an operation start instruction of the operation panel 31.
Here, the processing in the first drying operation (step S61 to step S63) and the second drying operation (step S63 to step S64) is a drying operation corresponding to the third processing.
As described above, each process in the humidification operation of the liquid level-reducing device 1 is performed in the heat exchange ventilator 60.
As described above, according to the liquid reducing device 1 of embodiment 2, the following effects can be obtained.
(1) In the liquid refining apparatus 1, when the number of times of supplying water to the water storage portion 14 reaches a predetermined number (more than M times) in the humidification operation (the refining operation), the first process of discharging the water in the water storage portion 14 is performed. Thus, when the number of times of supplying water to the water storage 14 reaches a predetermined number (more than M times) during the humidification operation, the water in the water storage 14 (water in which scale components are concentrated) is discharged and removed by performing the first treatment. Therefore, the increase in the concentration of scale components in the water storage unit 14 can be suppressed. As a result, the scale component contained in the water storage portion 14 can be reduced from entering the separator 17 during the subsequent humidification operation. That is, when the apparatus is used continuously for a long period of time, the liquid micronizing apparatus 1 can be made capable of suppressing occurrence of clogging in the apparatus.
(2) The liquid refining apparatus 1 is configured to execute a first process of discharging water in the water storage portion 14 when the number of times of supplying water to the water storage portion 14 reaches a predetermined number (more than M times) in a humidification operation (a refining operation). In the first treatment, since the water in the water storage portion 14 is discharged every predetermined number of times by the number of times of supplying the water to the water storage portion 14, the amount of water used can be reduced as compared with the case of discharging water each time. Therefore, the running cost of the liquid refining apparatus 1 can be reduced. The prescribed number of times is a number of times of two or more.
(3) In the liquid refining apparatus 1, when the humidification operation (the refining operation) is continued for a predetermined time (the second time T2), the second process of discharging the water in the water reservoir 14 is performed. Thus, when the humidification operation is continued for a predetermined time (second time T2), the water in the water storage portion 14 (water in which the scale components are concentrated) is discharged and removed by performing the second treatment. That is, in the liquid refining apparatus 1, the increase in the concentration of scale components in the water storage portion 14 can be reliably suppressed by the first treatment or the second treatment.
(4) In the liquid refining apparatus 1, after the second process is completed, the third process of performing the air blowing from the blower 67 is performed while the humidification operation (the refining operation) is performed in a state where the water storage portion 14 is free of water. Thus, the inside of the apparatus can be dried after the completion of the third process, and thus, when the liquid refining apparatus 1 is kept in a stopped state for a long period of time, propagation of mold, bacteria, and the like in the apparatus can be suppressed.
(5) In the liquid micronizing device 1, in the humidifying operation (micronizing operation), the water in the water storage portion 14 is swirled by the rotation in the water pipe 9 to generate a vortex 24, and a space 25 communicating between the water pipe 9a and the water outlet 16a is formed in the center of the vortex to block the water in the water storage portion. Further, by stopping the rotation of the rotation motor 11, the water in the first process or the second process is discharged. With this configuration, the liquid level-reducing device 1 can perform water blocking and water drainage in the liquid level-reducing device 1 without using a drain valve. Therefore, the opening area of the drain port 16a can be increased or the inner diameter of the drain pipe 16 can be increased, so that the liquid reducing device 1 is capable of reducing clogging due to the drain mechanism.
(6) In the liquid refining apparatus 1, the bottom surface of the water storage portion 14 is formed in a mortar shape inclined downward toward the water lifting port 9 a. Thus, when the water lifting pipe 9 rotates, a centrifugal force is easily applied to the water stored in the water storage portion 14. Therefore, the vortex flow 24 can be easily generated in the water storage portion 14 inside the water lifting pipe 9, and the generated vortex flow 24 can be stably continued. In addition, when the rotation of the water lifting pipe 9 is stopped, the water stored in the water storage portion 14 can be reliably discharged from the water discharge port 16 a.
(7) In the heat exchange ventilator 60, the humidity recovery unit 65 is disposed upstream of the liquid micronizing device 1 in the flow of air passing through the liquid micronizing device 1 and the humidity recovery unit 65. In other words, in the heat exchange ventilator 60, the liquid micronizing device 1 is disposed 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 micronizing device 1, so that humidity control can be performed more appropriately. Further, by performing humidity control at two places of the humidity recovery unit 65 and the liquid refining apparatus 1, a sufficient amount of humidification can be ensured even when the humidity recovery unit 65 or the liquid refining apparatus 1 is not provided with a heater or the like. In addition, a heater for ensuring the humidification amount is not required, so that energy saving can be achieved.
While the present invention has been described above with reference to the embodiments, it is to be understood that the present invention is not limited to the above embodiments, and various modifications and changes can be made without departing from the spirit of the present invention. For example, the numerical values recited in the above embodiments are examples, and other numerical values may be used.
In the heat exchange ventilator 60, the humidity recovery unit 65 may have a function of recovering (exchanging) not only the humidity but also the temperature. Specifically, the humidity recovery unit 65 serves as a total heat exchange element, and an exhaust blower is provided in the main body case 50 to constitute an exhaust air passage. The exhaust air passage is an air passage through which the exhaust blower sucks in indoor air from the internal air intake port 61 and through which the humidity recovery unit 65 exhausts the indoor air from the exhaust port 62 to the outside. At this time, the humidity recovery unit 65 is disposed at a position where the exhaust air passage and the supply air passage intersect. The humidity recovery unit 65 exchanges heat between the air passing through the exhaust duct and the air passing through the supply duct, and performs humidity exchange. Thereby, more comfortable air can be supplied into the room.
In the heat exchange ventilator 60, the air after humidity is recovered by the humidity recovery unit 65 may be supplied to the room by bypassing the liquid micronizer 1 so as not to flow through the liquid micronizer 1. Accordingly, when the liquid refining apparatus 1 is not operated but is operated only by heat exchange ventilation, the air after the humidity recovery can be efficiently supplied into the room. Further, since the increase in pressure loss caused by the liquid refining apparatus 1 can be suppressed, the energy-saving operation throughout the year can be realized.
In the heat exchange ventilator 60, the operation of the blower 67 is stopped by stopping the blowing from the blower 67, but the present invention is not limited thereto. For example, the bypass may be switched to avoid blowing air into the liquid reducing apparatus 1. Thus, the drying operation in the drying process can be performed in an independent state while the air supply to the room is performed.
In the liquid refining apparatus 1, the humidification control portion 30 controls the supply of water to the water storage portion 14 when the water level detection portion 18 is in an off state for a predetermined time (first time T1) with respect to the supply of water from the water supply portion 15 to the water storage portion 14, and is not limited thereto. For example, the humidification control portion 30 may control the supply of water to the water storage portion 14 when the amount of decrease in water in the water storage portion 14 due to the humidification operation reaches a predetermined water amount V. In this case, whether or not the predetermined water amount V is reached is determined by calculating an estimated water amount that decreases in accordance with the humidification conditions (humidification amount, air supply amount) during the humidification operation at regular intervals (for example, 1 minute or 5 minutes), and accumulating them. Thus, since the accuracy of controlling the amount of water (or the remaining amount) in the water storage portion 14 can be improved, unnecessary water supply (water supply in a state where the water in the water storage portion 14 is not reduced) can be suppressed.
In the liquid refining apparatus 1, the humidification control portion 30 may control to stop the rotation of the water lifting pipe 9 (the rotation motor 11) when it is determined that the humidity of the air sucked from the suction port 2 exceeds the target humidity and when the humidity of the air sucked from the suction port 2 becomes the first humidity higher than the target humidity. Here, the first humidity is set to 120% of the target humidity, for example. In this way, the humidification control portion 30 can suppress excessive humidification of the air sucked from the suction port 2, and thus can more appropriately control the humidity in the room.
In the liquid refinement apparatus 1, the humidification control portion 30 determines whether humidification (water refinement) is necessary 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.
First, the humidification control portion 30 calculates the amount of humidification required to achieve the target humidity based on the first information (target humidity, ventilation air volume) from the operation panel 31 and the fourth information (temperature and humidity of the air sucked into the suction port 2) from the temperature and humidity sensor 34. The humidification control portion 30 calculates the rotation speed of the rotary motor 11 when the calculated humidification amount is achieved. As a result, if the calculated rotation speed of the rotary motor 11 is less than 2000rpm, the humidification control portion 30 determines that humidification is not necessary, and if it is 2000rpm or more, determines that humidification is necessary. If the calculated rotation speed is in the range of 2000rpm to 4000rpm, the humidification control portion 30 sets the calculated rotation speed to the second rotation speed R2. On the other hand, in the case where the calculated rotation speed exceeds 4000rpm, 4000rpm is set as the second rotation speed R2. When the calculated rotation speed is less than 2000rpm after the start of the water miniaturization operation, the fourth rotation speed R4 (the rotation speed at which the water blocking mechanism functions) is set in its entirety.
