- a device has been proposed that includes an energizing section that energizes the base material section and a control section that controls the energizing section (for example, see Patent Document 1).
- moisture in the air is adsorbed by reducing the temperature of the fine water emitting element by de-energizing the base material using the current-carrying part, and releasing fine water by making the base material part energized by the current-carrying part. Fine water is released from the fine water emitting element as the temperature of the element increases.
- the base material portion when adsorbing moisture, the base material portion is simply de-energized and the temperature is not controlled. For this reason, adsorption of moisture onto the fine water emitting element is promoted, the amount of water becomes excessive, and adjacent water particles absorbed by the fine water emitting element may bond with each other. It is thought that the combined water particles become less likely to be released as fine water even if the temperature of the fine water emitting element increases.

- the fine water emitting device of the present disclosure includes moisture absorption control that supplies first energy that brings the fine water emitting element into a moisture absorbing state, and second energy that makes the fine water emitting element higher in temperature than the moisture absorbing state and brings the fine water releasing element into a moisture releasing state.

Therefore, it is possible to suppress the binding of water particles and increase the adsorption ratio of water particles that become fine water to the total amount of water adsorbed, so that release of fine water during moisture release control can be promoted.

- the state changes to a state where moisture is released from the polymer membrane 36.
- the thickness of the conductive polymer film 36 can be determined as appropriate depending on the required adsorption amount (release amount) of fine water.

It is determined whether the temperature is below the temperature (S210).
- the first temperature is set to be higher than the environmental temperature, which is the temperature around the fine water discharge device 10.
- the first temperature is preset at, for example, 50° C., which is a temperature that normally does not fall below the environmental temperature.
- the control unit 50 determines that the temperature of the fine water emitting element 34 is equal to or lower than the first temperature, the control unit 50 sets the first energization state (weak energization state) in which a relatively small current (small current) is caused to flow to the base material 35.

Note that when the moisture absorption control is executed immediately after the start of the fine water release process, the control unit 50 normally determines that the temperature is below the first temperature in S210 and energizes in S220. Therefore, the temperature of the fine water emitting element 34 increases.

- the fan 40 is rotated at a low speed (S240), and the moisture absorption control is ended.
- the control section 50 stops energizing the fine water generation cartridge 30 and rotates the fan 40 at a low speed. Therefore, even if energization is started to the fine water generation cartridge 30 in S220, it is possible to suppress the temperature of the fine water emitting element 34 from rising above the second temperature.
- the moisture release control in S120 is executed based on the flowchart in FIG.
- the control unit 50 first rotates the fan 40 at a low speed so as to blow air at a relatively slow wind speed (predetermined wind speed) (S300).
- predetermined wind speed predetermined wind speed
- the control unit 50 only needs to rotate the fan 40 at a lower speed than in S200, and in this embodiment, the control unit 50 rotates the fan 40 at the same speed as in S240.
- the control unit 50 determines whether the temperature of the fine water emitting element 34 detected by the internal temperature sensor 57 is equal to or lower than the third temperature (S310).
- the third temperature is predetermined as a temperature higher than the above-mentioned second temperature, such as 65° C., for example.
- the control unit 50 determines that the temperature of the fine water emitting element 34 is equal to or lower than the third temperature
- the control unit 50 sets the second energization state (strong energization state) to flow a relatively large current (large current) to the base material 35.
- a control signal is output to the energization circuit 38 to energize the fine water generation cartridge 30 with a large current (S320). That is, in the moisture release control, the control unit 50 causes the fine water generation cartridge 30 to pass a current larger than that in the moisture absorption control, thereby raising the temperature of the fine water release element 34 higher than in the moisture absorption state. Further, if the control unit 50 determines that the temperature of the fine water emitting element 34 is not lower than the third temperature, it skips S320.
- the control unit 50 determines in S310 that the third temperature is lower than the third temperature, and in S320, a large current is applied to the fine water generation cartridge 30. energize.
- the control unit 50 determines whether the temperature of the fine water emitting element 34 detected by the internal temperature sensor 57 has reached the fourth temperature (S330).
- the fourth temperature is predetermined as a temperature higher than the third temperature by several degrees Celsius to ten degrees Celsius, for example, 75 degrees Celsius.
- the control unit 50 determines that the temperature of the fine water emitting element 34 has not reached the fourth temperature, it ends the moisture release control.
- the control unit 50 determines that the temperature of the fine water emitting element 34 has reached the fourth temperature, it stops energizing the fine water generating cartridge 30 (S340) and ends the moisture release control.
- the control unit 50 stops energizing the fine water generating cartridge 30. Thereby, it is possible to suppress the temperature of the fine water emitting element 34 from rising above the fourth temperature.
- the control unit 50 determines that the second time has elapsed in S130, and determines that it is not the stop timing in the subsequent S140, it switches to moisture absorption control in S100 (FIG. 5).
- the moisture absorption control since the control unit 50 rotates the fan 40 at high speed in S200, it is possible to quickly cool the fine water emitting element 34 whose temperature has risen to between the third temperature and the fourth temperature. Further, the control unit 50 rotates the fan 40 at high speed until the temperature of the fine water discharge element 34 decreases and reaches the second temperature, and when it is determined in S230 that the temperature of the fine water discharge element 34 has reached the second temperature. , the fan 40 is rotated at low speed in S240.
- the control unit 50 performs moisture absorption control between the first temperature and the second temperature (for example, 50°C to 55°C) and between the third temperature and the fourth temperature (for example, 65°C to 75°C). Execute while switching between moisture release control and moisture release control. Therefore, a temperature difference of approximately 10 to 20° C. occurs between the time of moisture absorption and the time of moisture release. If the temperature at the time of moisture absorption decreases by about 10 to 20 degrees Celsius from the temperature at the time of moisture release, the fine water release element 34 will appropriately change to the moisture absorption state and release fine water even if the temperature is higher than normal temperature, for example about 25 degrees Celsius. It becomes possible to absorb moisture.
- FIG. 8 is a schematic diagram of the conductive polymer film 36 in a hygroscopic state in a comparative example.
- FIG. 9 is a schematic diagram of the conductive polymer film 36 in a hygroscopic state in this embodiment.
- FIG. 10 is an explanatory diagram showing an example of the relationship between the temperature during hygroscopicity and the ion current.
- no current is passed through the fine water generating cartridge 30 (substrate 35) in the hygroscopic control, and the hygroscopic control is performed when the fine water emitting element 34 (substrate 35) is at room temperature, for example, about 25°C.
- the hygroscopic control is performed when the fine water emitting element 34 is at a relatively high temperature, such as 50 to 55°C.
- the left bar graph in FIG. 10 shows the comparative example, and shows the ion current detected when, for example, the hygroscopic control is performed at room temperature of about 25°C and the hygroscopic control is performed at about 45°C.
- the right bar graph in FIG. 10 shows the present embodiment, and shows the ion current detected when, for example, the hygroscopic control is performed at a high temperature of about 55°C and the hygroscopic control is performed at about 67°C.
- the amount of fine water discharged was determined by passing the fine water discharged from the fine water discharge element 34 through a neutralizer to charge it, measuring the electrical mobility of the charged fine water with a differential mobility analyzer, classifying it, and measuring the current (charge) of fine water of 50 nanometers or less. A larger ion current indicates a larger amount of fine water discharged under moisture release control.
- the water particles W of adjacent sulfonic acid groups combine to form bulk water, and the nanochannel 36c is filled with water. It is thought that the bound water particles W are less likely to exist in a cluster state with a particle size of about 2 nanometers or less, and are less likely to be released as fine water in a moisture-releasing state. As a result, the amount of released fine water of 50 nanometers or less is reduced (see FIG. 10).
- the fine water release element 34 is brought to a high temperature state by moisture absorption control, so the shell (PSS 36b) contracts and at the same time, the nanochannel 36c becomes smaller.
- the shell (PSS 36b) contracts and at the same time, the nanochannel 36c becomes smaller.
- the number of sites that can adsorb water within the nanochannel 36c decreases, and the total amount of water that can be adsorbed decreases.
- the number of water particles W existing in a cluster state with a particle size of about 2 nanometers or less increases.
- the amount of fine water of 50 nanometers or less released is greater than that of the comparative example (see FIG.
- the PSS 36b of the shell further contracts.
- the release of fine water from within the nanochannels 36c is promoted by the temperature rise, contraction of the shell (PSS 36b), and the above-mentioned difference in water concentration between the surface and the inside of the element.
- the fine water discharge device 10 discharges fine water toward the skin, hair, etc. of the human body.
- the stratum corneum on the surface of the skin has minute gaps of about 20 to 50 nanometers or less. Therefore, if the particle size of the fine water is 50 nanometers or less, it is easy for the fine water to penetrate from the stratum corneum into the inside of the skin.
- the particle size of the fine water is 50 nanometers or less, it is easy for the fine water to penetrate into the inside of the hair.
- the fine water discharge device 10 of this embodiment makes it easier for water particles W to exist in a state of 50 nanometers or less when absorbing moisture, thereby promoting the discharge of fine water of 50 nanometers or less when releasing moisture, and improving the effect of penetrating the fine water into the skin and hair. This allows the fine water to fully penetrate the skin and hair, resulting in an improved moisturizing effect.
- the fine water discharge device 10 of the present embodiment described above performs moisture absorption control in which a small current is applied so that the fine water discharge element 34 enters the moisture absorption state, and the temperature of the fine water discharge element 34 is made higher than the temperature in the moisture absorption state.
- the moisture release control is performed by applying a large current to bring the moisture into the moisture release state.
- the amount of water adsorbed to the conductive polymer film 36 is controlled, the binding of water particles W is suppressed, and the total amount of water is It is possible to increase the adsorption ratio of water particles W that become fine water. Therefore, appropriate release of fine water can be promoted.
- control unit 50 starts applying a small current when the temperature of the fine water releasing element 34 is below the first temperature, and stops applying the current when the temperature is above the second temperature, so that the fine water is released. It is possible to prevent the temperature of the element 34 from becoming too high and being unable to absorb moisture.
- control unit 50 starts applying a large current when the temperature of the fine water emitting element 34 is below the third temperature, and stops applying the large current when the temperature is above the fourth temperature. It is possible to suppress excessive temperature rise while ensuring a temperature difference between the two and performing appropriate moisture absorption and desorption.
- control unit 50 rotates the fan 40 at low speed during moisture release control and rotates the fan 40 at high speed when starting moisture absorption control, the fine water release element 34 is cooled during moisture absorption control after moisture release control. can be quickly brought into a moisture-absorbing state.
- the PSS 36b of the shell contracts and suppresses the amount of water adsorbed in the nanochannels 36c, so that the total amount of water adsorbed is lower than that when adsorbed at room temperature. Although this decreases, the proportion of water particles W that becomes fine water increases.
- the PSS 36b of the shell further contracts, and fine water is released from within the nanochannel 36c due to the difference in water concentration between the element surface and the inside.
- the fine water discharge device 10 can absorb and release moisture by making the fine water discharge element 34 having the conductive polymer film 36 having a core-shell structure function more appropriately.
- the fan 40 is rotated at high speed in step S200 of the moisture absorption control, but it is usually not necessary to operate the fan 40 at high speed for cooling in the moisture absorption control immediately after the start of the fine water release process (first time). S200 may be omitted.
- the method is not limited to rotating the fan 40 at high speed under moisture absorption control, and the following method may be used.
- FIG. 11 is a flowchart showing a modified example of fine water release processing.
- FIG. 12 is a flowchart showing moisture absorption control in a modified example. In the following modified examples, the same step numbers are given to the same processes as in the embodiment, and the description thereof will be omitted.
- the control unit 50 determines that it is not the stop timing in S140, it performs cooling control to rotate the fan 40 at high speed for a predetermined period of time (S145), and then performs cooling control in S100. Shift to moisture absorption control. That is, the fine water release process of the embodiment ( Figure 5) is different.
- the predetermined time in the cooling control in S145 is predetermined as the time required to bring the fine water discharge element 34, which has become relatively high temperature due to the moisture absorption control, to the temperature of the moisture absorption state.
- control unit 50 operates the fan 40 at high speed until it detects that the temperature of the fine water discharge element 34 has reached a temperature at which moisture is absorbed (for example, a second temperature or lower). After the rotation, the process may proceed to moisture absorption control in S100.
- the control unit 50 first rotates the fan 40 at a low speed so as to blow air at a relatively slow wind speed (predetermined wind speed) (S200B). Further, if the control unit 50 determines in S230 that the temperature of the fine water emitting element 34 has reached the second temperature, it stops the power supply to the fine water generating cartridge 30 (S240B), and ends the moisture absorption control. In this way, in the moisture absorption control of the modified example, the fan 40 is rotated at low speed when moisture absorption control is started, and the fan 40 is kept rotating at low speed without being stopped when moisture absorption control is ended.
- predetermined wind speed predetermined wind speed
- the fine water releasing element 34 can adsorb moisture in a period of about several seconds to several tens of seconds. Therefore, if the temperature of the fine water release element 34 reaches the second temperature during the first time (S110) during which the moisture absorption control is performed and moisture is adsorbed by the fine water release element 34, the moisture absorption control is performed. There is no need to provide cooling control (S145) between this and moisture release control.

This fine water discharge device 10B is equipped with an environmental temperature sensor 58 that detects the environmental temperature, which is the temperature around the fine water discharge device 10. The control unit 50 may set the first to fourth temperatures based on the environmental temperature detected by the environmental temperature sensor 58.
- control unit 50 may set the first temperature by adding a temperature of several tens of degrees Celsius, such as 20°C to 30°C (first predetermined temperature) to the environmental temperature detected by the environmental temperature sensor 58, and set the second temperature by adding a temperature of several degrees Celsius to tens of degrees Celsius (second predetermined temperature) to the first temperature.
- the control unit 50 may also set the third temperature by adding a temperature of several tens of degrees Celsius to tens of degrees Celsius (third predetermined temperature) to the second temperature, and set the fourth temperature by adding a temperature of several degrees Celsius to tens of degrees Celsius (fourth predetermined temperature) to the third temperature.
- control unit 50 may selectively set the first to fourth temperatures based on the environmental temperature detected by the environmental temperature sensor 58. For example, the control unit 50 sets temperatures 1A, 2A, 3A, and 4A as the first temperature, second temperature, third temperature, and fourth temperature, respectively when the environmental temperature is low, and when the environmental temperature is high. In this case, temperature 1B, temperature 2B, temperature 3B, and temperature 4B are set respectively. Each temperature is defined as temperature 1A, temperature 1B, temperature 2A, temperature 2B, temperature 3A, temperature 3B, temperature 4A, temperature 4B from the lowest one, and is determined in advance and stored in a storage unit such as a ROM of the control unit 50. Bye. Further, the control unit 50 may change the settings of the first to fourth temperatures in accordance with changes in the environmental temperature during execution of the fine water release process.
- the fan 40 changes the wind speed in two stages, but the fan 40 is not limited to this, and the wind speed may be changed in three or more stages.
- control unit 50 terminates the passage of current when the second temperature is reached in moisture absorption control (when the temperature is equal to or higher than the second temperature), but this is not limited to the above and the amount of current flow may be reduced to suppress temperature rise. Also, the control unit 50 terminates the passage of current when the fourth temperature is reached in moisture release control (when the temperature is equal to or higher than the fourth temperature), but this is not limited to the above and the amount of current flow may be reduced to suppress temperature rise.
