The output unit 21e includes a blower 30 (control unit 30a), a chemical liquid supply unit 20 (leading valve 20a), a liquid miniaturization means 17, a water supply valve 18a of the water supply pipe 18, and a drainage valve 19a of the drainage pipe 19. It is electrically connected. Then, based on the received control information, the output unit 21e blows air from the blower device 30, miniaturizes the liquid miniaturization means 17 (first miniaturization operation to third miniaturization operation described later), and supplies water. A signal (control signal) for controlling the opening / closing operation of the valve 18a, the opening / closing operation of the drain valve 19a, and the derivation operation of the chemical liquid supply unit 20 is output.

Then, each device (the blower 30, the chemical supply unit 20, the liquid miniaturization means 17, the water supply valve 18a, the drain valve 19a, the lead-out valve 20a) receives the signal from the output unit 21e, and based on the received signal. Take control.

As described above, the humidification control unit 21 controls the humidification operation in the humidification mode and the chemical solution cleaning operation in the chemical solution cleaning mode.

Next, the humidification operation in the humidification mode of the liquid miniaturization apparatus 1 will be described with reference to FIG. When the control signal related to the humidification operation is input from the humidification control unit 21, the liquid miniaturization device 1 executes the following processing, and the blower device 30 blows air by the control signal from the humidification control unit 21. It is assumed that the operation is being performed.

In the liquid miniaturization device 1, first, water is supplied from the water supply facility (not shown) to the water storage unit 10 from the water supply port 12, and the water is stored in the water storage unit 10. The air sucked into the liquid miniaturization device 1 from the suction port 2 (air blown from the blower device 30) is the suction communication air passage 5, the inner cylinder air passage 6, the liquid miniaturization means 17, and the outer cylinder. It passes through the air passages 9 in this order, and is blown out from the air outlet 3 toward the outside (for example, indoors). At this time, the water droplets generated by the liquid miniaturization means 17 come into contact with the air passing through the inner cylinder air passage 6, and the water droplets are vaporized to humidify the air. Further, the water stored in the water storage unit 10 is discharged from the drain port 13 to the outside of the device through the drain pipe 19 after a predetermined time has elapsed.

This will be described in more detail.

As shown in FIG. 2, the air that has passed through the suction communication air passage 5 from the suction port 2 and is taken into the inner cylinder of the inner cylinder air passage 6 passes through the liquid miniaturization means 17. When the pumping pipe 14 and the perforated portion 15 are rotated by the operation of the motor 16, the water stored in the water storage portion 10 by the rotation rises along the inner wall surface of the pumping pipe 14. The rising water passes through the inside of the porous portion 15 and is made finer, and is discharged as fine water droplets from the outer peripheral surface of the porous portion 15 toward the rotating surface. Further, the released water droplets collide with the inner wall surface of the inner cylinder 4 and are crushed to become finer water droplets. The water droplets discharged from the porous portion 15 and the water droplets crushed by colliding with the inner wall surface of the inner cylinder 4 come into contact with the air passing through the inner cylinder 4, and the water droplets are vaporized to humidify the air. Although a part of the generated water droplets is not vaporized, since the liquid micronizing means 17 is arranged so as to be covered with the inner cylinder 4, the unvaporized water droplets adhere to the inner surface of the inner cylinder 4. It falls into the water storage unit 10.

Then, the air containing water droplets (humidified air) is blown out from the ventilation port 7 provided at the lower end of the inner cylinder 4 toward the water storage portion 10 provided below. Then, it flows toward the outer cylinder air passage 9 formed between the inner cylinder 4 and the outer cylinder 8. Here, since the air passing through the outer cylinder air passage 9 is blown upward in the vertical direction, the air flowing downward in the inner cylinder air passage 6 and the air blowing direction are changed to face each other.

At this time, the water droplets blown out from the ventilation port 7 together with the air cannot follow the flow of the air due to its inertia, and adhere to the water surface 40 of the water storage unit 10 or the inner wall surface of the outer cylinder 8. The heavier the weight of the water droplets, the greater the action, that is, the larger the diameter of the water droplets, which is less likely to vaporize, the greater the action.

Then, the air that has flowed from the inner cylinder air passage 6 into the outer cylinder air passage 9 through the ventilation port 7 flows upward through the outer cylinder air passage 9. Then, it is blown out from the outlet 3. At this time, a part of the water droplets falls to the water storage unit 10 due to gravity, or adheres to the outer wall of the inner cylinder 4 or the inner wall of the outer cylinder 8. Then, the water droplets adhering to the outer wall of the inner cylinder 4 and the inner wall of the outer cylinder 8 fall to the water storage unit 10 along the outer wall surface of the inner cylinder 4 and the inner wall surface of the outer cylinder 8.

As described above, the liquid miniaturization device 1 can humidify the sucked air by the liquid miniaturization means 17. Then, the liquid miniaturization device 1 continuously executes the humidification operation (water miniaturization operation) by the liquid miniaturization means 17 based on the control signal regarding the humidification operation from the humidification control unit 21.

On the other hand, the liquid miniaturization apparatus 1 according to the present embodiment executes a cleaning operation in the chemical solution cleaning mode in order to remove the scale component precipitated in the porous portion 15 of the liquid miniaturizing means 17. Specifically, the liquid miniaturization device 1 stops blowing air from the blower device 30 as a cleaning operation of the porous portion 15, supplies the chemical solution from the chemical solution supply unit 20 to the water storage unit 10, and then water containing the chemical solution. The miniaturization operation is executed for. As the ventilation from the blower device 30 is stopped, the backflow prevention damper is shut off from the open state (the state in which the suction port 2 and the air supply port 34 communicate) to the closed state (the suction port 2 and the air supply port 34 are cut off). Can be switched to.

The cleaning operation in the chemical solution cleaning mode of the liquid miniaturization apparatus 1 will be described in more detail with reference to FIG. FIG. 5 is a flowchart showing a processing procedure by the liquid miniaturization apparatus according to the first embodiment of the present invention.

Here, the chemical washing mode is executed when a predetermined condition is satisfied. Specifically, in the chemical solution cleaning mode, (a) when instruction information regarding the start of operation of the liquid miniaturization device 1 is input as the first information, or (b) the liquid miniaturization device 1 included in the fifth information. Executed when the conditions for switching to the chemical cleaning mode of The condition for switching to the chemical washing mode in (b) is, for example, a periodic timing (for example, once every 24 hours). Further, when the humidification control unit 21 is connected to the sensor that detects the presence of a person, the chemical solution cleaning mode is not executed for a predetermined period (for example, 24 hours or more) as the switching condition to the chemical solution cleaning mode. Moreover, the timing may be such that there are no people indoors.

As shown in FIG. 5, when the chemical cleaning mode is started, the humidification control unit 21 stops the ventilation from the blower device 30 to stop the water supply to the water storage unit 10 and the drainage from the water storage unit 10. (Step S21). Here, the blowing from the blower 30 is stopped by stopping the operation of the blower 36. Further, the water supply stop is performed by closing the water supply valve 18a, and the drainage stop is performed by closing the drain valve 19a. Next, the humidification control unit 21 opens the lead-out valve 20a of the chemical solution supply unit 20 to charge a predetermined amount of the chemical solution from the chemical solution supply unit 20 to the water storage unit 10 (step S12). As a result, the water in the water storage unit 10 is in a state in which the chemical solution is added.

Next, the humidification control unit 21 operates the liquid miniaturization means 17 to start the chemical solution cleaning (step S13). Then, when the predetermined time T1 has elapsed from the start of the chemical solution cleaning (Yes in step S14), the humidification control unit 21 stops the liquid miniaturization means 17 and ends the chemical solution cleaning (step S15). If T1 has not elapsed for a predetermined time since the start of the chemical washing (No in step S14), the chemical washing is continued (returning to step S14). Here, the series of operations from step S13 to step S15 is referred to as the first miniaturization operation by the liquid miniaturization means 17. In the first miniaturization operation, water containing a chemical solution flows through the apparatus to clean the inside of the apparatus (particularly the porous portion 15 of the liquid miniaturization means 17) (remove the precipitated scale component).

Next, when the chemical solution cleaning is completed, the humidification control unit 21 opens the drain valve 19a and drains the water (water containing the chemical solution) in the water storage unit 10 to the outside from the drain port 13 (step S16). Then, when the drainage is completed, the humidification control unit 21 closes the drain valve 19a, opens the water supply valve 18a, and supplies the water storage unit 10 with new water (step S17).

Next, when the water supply to the water storage unit 10 is completed, the humidification control unit 21 operates the liquid miniaturization means 17 to start water cleaning (step S18). Then, when the predetermined time T2 has elapsed from the start of the water cleaning (Yes in step S19), the humidification control unit 21 stops the liquid miniaturization means 17 and ends the water cleaning (step S20). If T2 has not elapsed for a predetermined time since the start of water washing (No in step S19), water washing is continued (returning to step S19). Here, the series of operations from step S18 to step S20 is referred to as a second miniaturization operation by the liquid miniaturization means 17. In the second miniaturization operation, new water flows through the device to clean the inside of the device including the liquid miniaturization means 17 (removal of residual components caused by the chemical solution).

Next, when the water washing is completed, the humidification control unit 21 opens the drain valve 19a and drains the water (water after washing with water) in the water storage unit 10 to the outside from the drain port 13 (step S21). Then, when the drainage is completed, the humidification control unit 21 closes the drain valve 19a, opens the water supply valve 18a, and supplies the water storage unit 10 with new water (step S22).

Through the above processing procedure, the chemical cleaning mode is terminated, and the humidification control unit 21 returns to the humidification operation in the humidification mode.

As described above, according to the liquid miniaturization apparatus 1 according to the first embodiment, the following effects can be enjoyed.

(1) The humidification control unit 21 stops blowing air from the blower device 30 as a cleaning operation of the porous portion 15, supplies the chemical solution from the chemical solution supply unit 20 to the water storage unit 10, and then supplies the chemical solution to the liquid miniaturization means 17. The first miniaturization operation (a series of operations from step S13 to step S15 by the liquid miniaturization means 17) using water containing a chemical solution is executed. By doing so, in the first miniaturization operation performed as the cleaning operation of the porous portion 15, the porous portion 15 is cleaned with water containing a chemical solution, and the scale component (scale) deposited on the porous portion 15 can be removed. it can. Therefore, even when the device is used continuously for a long period of time, the liquid miniaturization device 1 capable of suppressing the occurrence of clogging in the porous portion can be obtained.

(2) The humidification control unit 21 drains the water containing the chemical solution in the water storage unit 10 and supplies new water to the water storage unit 10 after the completion of the first miniaturization operation using the water containing the chemical solution. Later, the liquid miniaturization means 17 is made to execute a second miniaturization operation (a series of operations from step S18 to step S20 by the liquid miniaturization means 17) using the new water supplied. By doing so, the residual component caused by the chemical solution can be reliably removed in the apparatus including the porous portion 15.

(3) The blower device 30 is provided on the upstream side of the liquid miniaturization device 1 in the flow of air passing through the liquid miniaturization device 1 and the blower device 30. In other words, the liquid miniaturization device 1 is provided on the downstream side of the blower device 30. At this time, since the air after the humidity is recovered by the humidity recovery unit 32 flows into the liquid miniaturization device 1, the humidity can be controlled more appropriately. Further, by controlling the humidity at two locations, the humidity recovery unit 32 and the liquid miniaturization device 1, a sufficient amount of humidification is secured even when a heater or the like is not installed in the humidity recovery unit 32 or the liquid miniaturization device 1. can do. In addition, energy saving can be realized by eliminating the need for a heater for securing the amount of humidification.

(Modification example)
The treatment procedure in the chemical solution washing mode in the modified example of the first embodiment is that the drying mode (treatment related to the drying operation) is executed after the drainage of the water storage unit 10 in step S21, and the chemical solution in the first embodiment is executed. It is different from the processing procedure in the cleaning mode. In the chemical washing mode, the treatment procedure up to step 21 is the same as the treatment procedure in the first embodiment. Hereinafter, the contents already explained in the first embodiment will be omitted again as appropriate, and the differences from the first embodiment will be mainly described.

An additional processing procedure in the chemical washing mode in the modified example of the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing another processing procedure by the liquid miniaturization apparatus according to the modified example of the first embodiment of the present invention.

Here, the chemical cleaning mode in the modified example is executed when (c) instruction information regarding the stop operation of the liquid miniaturization device 1 is input to the humidification control unit 21 as the first information.

When the chemical cleaning mode is started, as shown in FIG. 5, the humidification control unit 21 executes the treatment up to step S21 (wastewater treatment of the water storage unit 10). After that, the humidification control unit 21 executes a drying mode (process related to the drying operation).

Specifically, after the drainage of the water storage unit 10 is completed, the blower 36 is operated to start blowing air from the blower device 30 (step S23). As a result, air flows into the liquid miniaturization device 1 (liquid miniaturization means 17).

Next, the humidification control unit 21 operates the liquid miniaturization means 17 to start the drying operation (miniaturization operation when there is no water in the water storage unit 10) (step S24). Then, when the predetermined time T3 has elapsed from the start of the drying operation (Yes in step S25), the humidification control unit 21 stops the liquid miniaturization means 17 and ends the drying operation (step S26). If the predetermined time T3 has not elapsed since the start of the drying operation (No in step S25), the drying operation is continued (returning to step S25). Here, the series of operations from step S24 to step S26 is referred to as a third miniaturization operation by the liquid miniaturization means 17. In the third miniaturization operation, the inside of the device including the liquid miniaturization means 17 is dried (removal of moisture).

After the above processing procedure, the chemical cleaning mode is terminated, and the humidification control unit 21 stops the operation of the liquid miniaturization device 1. As a result, the liquid miniaturization device 1 is in a state of waiting for an operation start instruction from the operation panel 22.

As described above, according to the liquid miniaturization apparatus 1 according to the modified example of the first embodiment, the following effects can be enjoyed.

(4) The humidification control unit 21 drains water in the water storage unit 10 after the completion of the second miniaturization operation, and then performs a third miniaturization operation (liquid miniaturization means) in a state where there is no water in the water storage unit 10. A series of operations from step S24 to step S26 according to 17) is executed, and the air blown from the blower device 30 is started. By doing so, when the liquid miniaturization device 1 is stopped for a long period of time, it is possible to suppress the growth of mold, germs, etc. in the device.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It is easy to infer. For example, the numerical values given in the above embodiment are examples, and it is naturally possible to adopt other numerical values.

In the blower device 30 connected to the liquid miniaturization device 1 according to the present embodiment, the humidity recovery unit 32 may be configured to have a function of recovering (replacement) not only humidity but also temperature. Specifically, the humidity recovery unit 32 is used as a total heat exchange element, and an exhaust blower is provided inside the main body case 31 to form an exhaust air passage. The exhaust air passage is an air passage in which indoor air is sucked from the indoor air suction port 35 by an exhaust blower and exhausted to the outside from the exhaust port through the humidity recovery unit 32. At this time, the humidity recovery unit 32 is arranged at a position where the exhaust air passage and the air supply air passage 37 intersect. Then, the humidity recovery unit 32 exchanges heat and humidity between the air passing through the exhaust air passage and the air passing through the air supply air passage 37. This makes it possible to supply more comfortable air to the room.

Further, in the blower device 30 connected to the liquid miniaturization device 1 according to the present embodiment, the liquid miniaturization device 1 is used so that the air after the humidity is recovered by the humidity recovery unit 32 does not flow through the liquid miniaturization device 1. May be configured to be supplied indoors by bypassing. As a result, when the liquid miniaturization device 1 is not operated and only the blower device 30 is operated, the air after the humidity is recovered can be efficiently supplied to the room. Further, since the increase in pressure loss caused by the liquid miniaturization device 1 is suppressed, it is possible to realize energy-saving operation throughout the year.

Further, in the first embodiment, the blowing from the blower 30 is stopped by stopping the operation of the blower 36, but the present invention is not limited to this. For example, the switching to the bypass described above may prevent the air from being blown to the liquid miniaturization device 1. As a result, it is possible to perform the chemical cleaning operation in the chemical cleaning mode in an independent state while supplying air to the room.

Further, in the modified example of the first embodiment, a heater for heating the air blown from the blower device 30 is provided in the air supply air passage 37, and the heated air is blown in the drying mode (process related to the drying operation). You may try to do it. As a result, it is possible to surely eliminate the moisture in the device and dry it. Therefore, the effect of (4) above can be remarkably enjoyed.
