Description

Ion mist generator and heated air blower

[0001] The present disclosure relates to an ion mist generator and a heated air blower.

[0002] Hair dryers equipped with ion generators have been proposed. For example, when applying an ion generator to a hair dryer, it is desirable to generate a charged fine particle liquid (ion mist) containing a large amount of acidic components such as nitrate ions. Patent Document 1 discloses a hair care device equipped with an ion generator. The ion generator disclosed in Patent Document 1 generates a large amount of acidic components and ion mist while suppressing ozone generation by causing partial or full dielectric breakdown around the discharge electrode and counter electrode.

[0003] Japanese Patent Application Laid-Open No. 2020-32356

[0004] In the ion generator disclosed in Patent Document 1, dielectric breakdown between the electrodes occurs over a wide area. Therefore, when the discharge is strengthened to increase the amount of ions generated, a high current flows, which easily transitions to arc discharge, which generates loud noise and causes electrode wear. Therefore, there is a limit to the voltage that can be applied. Furthermore, if the distance between the electrodes is increased to prevent transition to arc discharge, the applied voltage required to generate discharge increases, resulting in an increase in the size of the device. Therefore, there is a need for a device that can increase the amount of acidic components and ion mist produced while preventing an increase in noise and electrode friction due to arc discharge.

[0005] The present disclosure provides an ion mist generator and a heated air blower that can increase the amount of acidic components and ion mist produced while preventing an increase in noise due to arc discharge and an increase in electrode friction.

[0006] An ion mist generator according to a first aspect of the present disclosure includes a discharge electrode, a liquid supply unit that supplies liquid to the discharge electrode, and a control unit that applies a voltage to the discharge electrode and controls the generation of ion mist by atomizing the liquid supplied from the liquid supply unit to the discharge electrode. The control unit causes the applied voltage to reach a predetermined voltage before the tip of a Taylor cone formed by the liquid becomes sharp as the voltage is applied and electrostatic atomization begins, and after the applied voltage reaches the predetermined voltage, stops supplying energy to increase and maintain the voltage.

[0007] A heated air blower according to a second aspect of the present disclosure includes a blower section that draws in air through an air inlet and discharges the air to the outside through an air outlet, and a heating section that heats the air downstream of the blower section. The heated air blower also includes an ion mist generating section that includes the above-mentioned ion mist generator and a component outlet that discharges the ion mist to the outside.

[0008] According to the present disclosure, it is possible to provide an ion mist generator and a heated air blower that can increase the amount of acidic components and ion mist produced while preventing an increase in noise due to arc discharge and an increase in electrode friction.

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] 1 is a schematic diagram showing the appearance of a heated air blower 10 according to this embodiment. The heated air blower 10 is, for example, a hair dryer, and discharges heated air from an air outlet 40. The heated air blower 10 also includes an ion mist generator 100, and discharges components such as ion mist (charged microparticle liquid) generated by the ion mist generator 100 from a component outlet 30.

[0012] Fig. 2 is a diagram illustrating the internal structure of the heated air blower 10 according to this embodiment. As shown in Fig. 2, the heated air blower 10 includes an air blower section 300 that takes in air through an air intake port 20 and discharges the air to the outside through an air outlet 40. The heated air blower 10 also includes a heating section 400 that heats the air downstream of the air blower section 300. The heated air blower 10 also includes an ion mist generator 100 and a component outlet 30 that discharges the ion mist to the outside. The ion mist generating section corresponds to a configuration including the ion mist generator 100 and the component outlet 30.

[0013] 2, the component outlet 30 and the air outlet 40 are arranged substantially parallel to each other. This allows the heated air blower 10 according to this embodiment to deliver a large amount of ion mist discharged from the component outlet 30 to the target object quickly, riding on the flow of air discharged from the air outlet 40.

[0014] 3 to 8 are diagrams for explaining the ion mist generator 100 according to this embodiment. The ion mist generator 100 comprises a discharge electrode 110, a liquid supply unit 130 that supplies liquid to the discharge electrode 110, and a control device 200 that applies a voltage to the discharge electrode 110 and controls the atomization of the liquid supplied from the liquid supply unit 130 to the discharge electrode 110. The ion mist generator 100 also comprises a counter electrode 120.

[0015] Fig. 3 is a diagram for explaining the application of voltage to the ion mist generator 100 according to this embodiment. In the circuit configuration shown in Fig. 3, under the control of the control device 200, a high voltage generated in the high voltage generator 250 is sent to the ion mist generator 100 via a limiting resistor 260. That is, the control device 200 controls the output waveform of the high voltage generator 250. Note that in this specification, the output voltage of the high voltage generator 250 corresponds to the high voltage generator output voltage V1 shown in Fig. 3. Furthermore, the voltage between the discharge electrodes 110 corresponds to the discharge electrode voltage V2 shown in Fig. 3.

[0016] The high-voltage generating unit 250 includes a step-up transformer 251, a diode 252, a capacitor 253, and a protective resistor 254. In this embodiment, the output waveform of the high-voltage generating unit 250 is a pulse output. In order to make the rise of the voltage applied to the discharge electrode 110 faster than the cone shape change, the time constant of the capacitor 253 and the limiting resistor 260 is realized so that it is shorter than the time required for the cone shape change. As an example, for a cone shape change of approximately 100 μs, C=4 pF, R=20 MΩ, and the time constant C×R=80 μs.

[0017] Furthermore, the control device 200 controls the applied voltage to reach a predetermined voltage before the tip of the Taylor cone formed by the liquid becomes sharp and the electrostatic atomization phenomenon begins. After the applied voltage reaches the predetermined voltage, the control device 200 stops the supply of energy to increase and maintain the voltage.

[0018] Figures 4, 5A, and 5B are diagrams for explaining the ion mist generator 100 according to this embodiment. Figure 4 is a diagram schematically showing the relationship between the discharge electrode 110, the counter electrode 120, and the liquid supply unit 130. Figures 5A and 5B are diagrams for explaining the discharge electrode 110 and the counter electrode 120 according to this embodiment.

[0019] The discharge electrode 110 is a rod-shaped electrode. The discharge electrode 110 has a spherical tip 110a (see FIG. 6) at one end (upper end) in the longitudinal direction (vertical direction), and a first columnar portion 110d at the other end (lower end, the end opposite to the spherical tip 110a) in the longitudinal direction.

[0020] The counter electrode 120 is disposed so as to face the spherical tip 110a of the discharge electrode 110. The counter electrode 120 is configured as a dome-shaped electrode as shown in Figures 4 and 5A. The discharge electrode 110 and the counter electrode 120 are made of, for example, titanium.

[0021] The discharge electrode 110 and the counter electrode 120 are arranged so that the central axis of the discharge electrode 110 and the central axis of the dome-shaped electrode of the counter electrode 120 coincide with each other.

[0022] 5B is a diagram for explaining ions generated by discharge. The counter electrode 120 may be used as an adsorption unit that adsorbs ions and ion mist of a given particle size or smaller. This can be achieved, for example, by adjusting the distance to the counter electrode 120 and the dome diameter. The adsorption unit corresponds to an ion adsorption unit.

[0023] Generally, hydrated ions obtained by hydrating ions generated by discharge with water molecules in the air have a small number of water molecules and a particle diameter of approximately 1 nm. On the other hand, charged fine water particles (ion mist) obtained by electrostatic atomization and discharge are often large, such as 3 nm or larger. Small ions are light and tend to be attracted to and adsorbed by the counter electrode due to an electric field. Therefore, by setting the position and shape of the counter electrode 120 so that particles of any size can be adsorbed, it is possible to selectively release only ion mist with large particle diameters. The adsorption portion may be provided separately from the counter electrode 120, or, as in the counter electrode described in Patent Document 1, protrusions around the counter electrode 120 that cause dielectric breakdown may function as adsorption portions.

[0024] The liquid supply unit 130 is realized, for example, by using a cooling device (not shown) that cools the discharge electrode 110 and causes condensation water to form on the discharge electrode 110 .

[0025] Furthermore, the liquid supply unit 130 may be provided with an adjusting unit that adjusts the amount of liquid supplied, and a time detection unit that detects the time that has elapsed since the start of operation, and adjust the amount of liquid supplied in accordance with a predetermined elapsed time.

[0026] This makes it difficult for the Taylor cone shape at the tip of the ion mist generator 100 to change, which makes it possible for the ion mist generator 100 to stabilize the Taylor cone shape and stabilize the amount of ion mist atomized.

[0027] The liquid supply unit 130 may also include an adjusting unit for adjusting the amount of liquid supplied, a temperature detecting unit for detecting the external environmental temperature, and a switching unit for switching the amount of ion mist required. The liquid supply unit 130 may also adjust the amount of liquid supplied depending on the amount of ion mist required and the external environmental temperature or humidity.

[0028] This makes it possible for the ion mist generator 100 to reduce the risk of excessive or insufficient ion mist even when the supply rate fluctuates due to changes in temperature, humidity, etc. As a result, the ion mist generator 100 can stabilize the Taylor cone shape and stabilize the amount of ion mist atomized.

[0029] The liquid supply unit 130 may also include an adjusting unit for adjusting the amount of liquid supplied, a temperature detector near the electrode for detecting the temperature near the discharge electrode, and a switching unit for switching the amount of ion mist required. The liquid supply unit 130 may also adjust the amount of liquid supplied in accordance with the amount of ion mist required and the temperature or humidity near the electrode.

[0030] This allows the ion mist generator 100 to control the supply amount by sensing the temperature near the discharge electrode, which has a large effect on the actual liquid supply amount (amount of condensation).As a result, the ion mist generator 100 has a more stable Taylor cone shape than when the amount of condensation is controlled in accordance with the external environmental temperature, making it possible to stabilize the amount of ion mist atomized.

[0031] FIG. 6 is a diagram for explaining the shape of the discharge electrode 110 in the ion mist generator 100 according to this embodiment.

[0032] 6, the discharge electrode 110 includes a first columnar section 110d, a convex curved portion provided at the tip of the first columnar section 110d, and a second columnar section 110b at the boundary between the first columnar section 110d and the convex curved portion, the second columnar section 110b having a larger diameter than the first columnar section 110d. The boundary between the second columnar section 110b and the first columnar section 110d is an arc-chamfered chamfered portion 110c. The convex curved portion corresponds to the spherical tip section 110a.

[0033] The Taylor cone has a spherical tip 110a as its base, and its shape is greatly affected by the balance between the electrostatic force generated between the Taylor cone and the counter electrode 120 due to the applied voltage and the force of adhesion to the discharge electrode 110 due to the surface tension of the liquid. Therefore, it is desirable for the Taylor cone to maintain a balanced state between the electrostatic force and the surface tension. The chamfered portion 110c serves to prevent changes in the surface tension acting on the Taylor cone by isolating the liquid adhering to the surface of the first columnar portion 110d. Furthermore, by increasing the contact area between the Taylor cone and the surface area of ​​the discharge electrode 110 using the second columnar portion 110b, the force of adhesion to the discharge electrode 110 is increased, making it less likely for the Taylor cone shape to change. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the amount of ion mist generated.

[0034] FIG. 7 is a diagram illustrating liquid supply amount control in the ion mist generator 100 according to this embodiment. As described above, the liquid supply unit 130 supplies the liquid for electrostatic atomization to the discharge electrode 110. For example, the left diagram in FIG. 7 shows a state without a Taylor cone. In this state, increasing the amount of liquid supplied from the liquid supply unit 130 causes the Taylor cone to form more quickly (Transition A in FIG. 7 , the transition from the left diagram to the middle diagram). Furthermore, the state shown in the middle diagram in FIG. 7 can be maintained by reducing the amount of liquid supplied from the liquid supply unit 130 in Transition B compared to Transition A.

[0035] FIG. 8 is a diagram illustrating the relationship between the amount of ion mist generated and the amount of liquid supplied in the ion mist generator 100 according to this embodiment. As shown in FIG. 8 , when the amount of ion mist generated is large and the amount of liquid supplied is small, the smaller the Taylor cone volume, according to the principles of electrostatic atomization, the larger the amount of ion mist generated. This results in excessive ion mist generation, increasing the risk of Taylor cone depletion. Furthermore, when the amount of ion mist generated is small and the amount of liquid supplied is large, the Taylor cone becomes too large, resulting in insufficient ion mist generation and an increased risk of arc discharge. Therefore, in the ion mist generator 100 according to this embodiment, the amount of ion mist generated and the amount of liquid supplied are adjusted so that the cone shape indicated by the dashed line in FIG. 8 is stable.

[0036] FIG. 9 is a block diagram showing the configuration of the control device 200 according to this embodiment. The control device 200 may be configured as a system including a general-purpose microcomputer including a control unit 210 (CPU (Central Processing Unit)), a storage unit 220 (memory), and an input / output IF 230 (Interface). In this case, a computer program for causing the heated air blower 10 to function may be installed in the microcomputer. By executing the computer program, the microcomputer functions as multiple information processing circuits included in the heated air blower 10. The control device 200 may also include a communication IF 240 that enables at least one of wired and wireless communication between the heated air blower 10 and the outside.

[0037] In this embodiment, an example is shown in which software is used to realize a plurality of information processing functions provided in the control device 200 of the hot air blower 10. The control device 200 executes a computer program to function as a plurality of information processing circuits provided in the hot air blower 10.

[0038] Alternatively, the control device 200 may be configured with dedicated hardware for executing each information processing function, such as a system LSI (Large Scale Integration). Alternatively, a system may be configured with multiple information processing functions each implemented by separate hardware. The control unit 210 and the storage unit 220 will be described in detail below.

[0039] The control unit 210 operates based on a program (not shown) stored in the storage unit 220, and executes each function of the control device 200. Note that the program is not limited to being stored in the storage unit 220, and may be stored, for example, in a ROM (not shown) within the heated air blower 10. The control unit 210 functions as a discharge electrode control unit 211, an air blowing control unit 212, a heating control unit 213, a component generation control unit 214, and a temperature detection unit 215, as shown in FIG.

[0040] As shown in FIG. 10, the storage unit 220 stores information stored in a setting information DB 221 (data base) and a detection information DB 222 as data in the storage unit 220 .

[0041] The setting information DB 221 stores, for example, setting information for controlling the heated air blower 10. This setting information may be information set in advance at the time of manufacture or by the user. The detection information DB 222 stores information such as air temperature, air volume, and room temperature detected by a temperature detection unit 215 (described later).

[0042] As described above, the storage unit 220 may also store programs for the various functions executed by the control unit 210. The information and programs stored in the storage unit 220 may be configured as physically or logically separated areas within a single storage device. Alternatively, the storage unit 220 for each piece of data may be configured in a plurality of physically separate storage devices.

[0043] The input / output IF 230 is an interface for transmitting and receiving information between the control device 200 and the high voltage generating unit 250, the blowing unit 300, the heating unit 400, the power switch, the level switch, etc., which are provided in the heated air blowing device 10.

[0044] For example, information regarding a power switch or a level switch pressed by the user is sent to at least one of the control unit 210 and the storage unit 220 via the input / output IF 230. In addition, control information for the high voltage generation unit 250, the air blower 300, and the heating unit 400 from the control unit 210 is sent to the high voltage generation unit 250, the air blower 300, and the heating unit 400 via the input / output IF 230.

[0045] The discharge electrode control unit 211 controls the voltage applied to the discharge electrode 110 from the output of the high voltage generation unit 250 via a limiting resistor 260. Fig. 11A is a diagram for explaining the high voltage generation unit output voltage V1 and discharge current of the ion mist generator 100 according to this embodiment. Fig. 11B is a diagram for explaining a comparative example of the discharge electrode voltage V2 and discharge current of the ion mist generator 100.

[0046] 11A , the discharge electrode control unit 211 controls the high voltage generation unit 250 to apply an applied voltage (pulse voltage). Furthermore, at time T2, the discharge electrode control unit 211 applies an applied voltage (pulse voltage). At time T3, the cone shape changes and a discharge occurs. That is, in this embodiment, the discharge electrode control unit 211 applies a pulse voltage as the applied voltage during the period from the start of the applied voltage (start of rising, time T1) to time T3, when the cone shape changes and a discharge starts.

[0047] 11A, the time from time T1 to time T3, which is the time from the start of application of the applied voltage until the cone shape changes and discharge occurs, is 100 μs. The pulses applied by the discharge electrode control unit 211 are applied at time T1 and time T2 during the period from time T1 to time T3.

[0048] In addition, in this embodiment, a negative high voltage output is obtained by boosting the voltage twice at times T1 and T2, but it is sufficient that the target voltage is reached by time T3, and the number of boosts is not limited to two, and the polarity of the output voltage may be either positive or negative.

[0049] That is, the ion mist generator 100 according to this embodiment causes the tip of the Taylor cone formed by the liquid to become sharp as a result of the application of the applied voltage, and causes the applied voltage to reach a predetermined voltage before the electrostatic atomization phenomenon begins. Furthermore, after the applied voltage reaches the predetermined voltage, the supply of energy to increase and maintain the voltage is stopped. This allows the ion mist generator 100 according to this embodiment to increase the amount of acidic components and ion mist produced while preventing an increase in noise and electrode wear due to arc discharge.

[0050] For example, as shown in FIG. 11B, the voltage V2 between the discharge electrodes reaches the target voltage by time T3, and when discharge starts at time T3 and a discharge current flows, the voltage drops significantly and the discharge stops, thereby achieving a stronger discharge and preventing arc discharge.

[0051] In the conventional configuration, when a DC voltage (direct current voltage) smoothed by a large-capacity output capacitor is applied, the voltage during discharge is lower than in the case of FIG. 11B , and the voltage is less likely to drop after discharge begins (after time T3 has elapsed). Therefore, as the discharge continues, dielectric breakdown progresses and arc discharge is likely to occur. Therefore, in order to prevent arc discharge, restrictions are placed on the voltage that can be applied. Furthermore, increasing the distance between the electrodes to prevent arc discharge increases the required voltage, which leads to issues such as an increase in the size of the device and increased noise.

[0052] On the other hand, the ion mist generator 100 according to this embodiment applies a high pulse voltage before the cone shape changes, rather than a DC voltage, thereby increasing the voltage at the start of discharge and preventing arc discharge while strengthening the discharge. This allows the ion mist generator 100 to increase the amount of acidic components and ion mist generated without increasing the size of the device.

[0053] The air blowing control unit 212 controls the air power of the air blowing unit 300 provided in the hot air blowing device 10. For example, the hot air blowing device 10 according to this embodiment may have wind power modes of weak air, medium air, and strong air.

[0054] The heating control unit 213 controls the heat generation amount of the heating unit 400 provided in the hot air blower 10. For example, the heating control unit 213 of the hot air blower 10 according to this embodiment controls the heating unit 400 so that the temperature of the air discharged from the air outlet 40 becomes a predetermined temperature.

[0055] The component generation control unit 214 controls the amount of ion mist generated by the ion mist generator 100. The component generation control unit 214 may also have a function of controlling the amount of components generated by the ion generation unit, acidic component generation unit, and transition metal microparticle generation unit, which will be described later.

[0056] The temperature detection unit 215 includes a room temperature detection unit 215a, an air temperature detection unit 215b, and a temperature detection unit near the electrodes 215c.

[0057] The room temperature detector 215a has a mechanism for detecting the room temperature. The air temperature detector 215b detects the temperature of the air discharged from the heated air blower 10. The electrode vicinity temperature detector 215c is provided near the ion mist generator 100 and detects the temperature near the discharge electrode 110.

[0058] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the embodiment. Furthermore, it is also possible to combine some or all of the various embodiments to create a new embodiment.

[0059] The heated air blower 10 according to the present embodiment described above is configured to include an ion mist generator 100. For example, the heated air blower 10 may be configured to include, in addition to the ion mist generator 100, a component generator having at least one of an ion generator, an acidic component generator, and a transition metal microparticle generator. The component generator may generate at least two or more components selected from the group consisting of ion mist, ions, acidic components, and transition metal microparticles.

[0060] This allows the heated air blower 10 to emit ion mist, ions, acidic components, or transition metal particles without inhibiting the release of each component. Therefore, the heated air blower 10 allows the ion mist, ions, acidic components, or transition metal particles to reach the hair without being deactivated in the air, further enhancing the hair care effect.

[0061] The component discharge ports 30 and the air discharge ports 40 of the component generating section may be arranged so that their discharge directions are substantially parallel to one another. This allows the components discharged by the heated air blower 10 to be carried by the flow of air discharged from the heated air blower 10 and delivered to the target object quickly and in large quantities.

[0062] Furthermore, the multiple component discharge ports 30 of the heated air blower 10 may be configured to be spaced apart in the approximate circumferential direction of the air discharge port 40. This allows the heated air blower 10 to stably supply the components to the target object regardless of the way the air is blown.

[0063] The heated air blower 10 may further include a generation amount control unit that controls two or more component generation units. The generation amount control unit may vary the component generation amount by controlling at least two or more independent units, thereby varying the component ratio generated by the component generation unit. The heated air blower 10 can achieve an appropriate finish depending on the usage mode for the object. The generation amount control unit corresponds to the component generation control unit 214.

[0064] In addition, the ion mist generating device 100 generates ions at a rate of at least 7,400 particles / cm ３ / s or more, more preferably 37,000 / cm ３ / s or more (at an air flow rate of 1.5 L / min). Generally, the amount of atomization based on the principle of electrostatic atomization results in fewer particles than the amount of ions generated by discharge. Therefore, even if the amount of mist generated is variable, it is difficult to significantly change the finish, or the finish may deteriorate due to the reduced amount of mist. By setting the mist generation amount as described above in this embodiment, the heated air blower 10 can enhance the sense of realism of the change in finish achieved by varying the amount of ion mist applied to the target object.

[0065] 12A to 12D are diagrams illustrating the modes provided in the heated air blower 10 according to this embodiment. For example, by changing the ratio of four components, namely, ion mist, acidic component, metal particles, and air ions, it is possible to achieve different finishes for the target hair. For example, as shown in FIGS. 12A to 12D, the different finishes correspond to a "moisturized and manageable mode," a "curl-straightening mode," a "soft and voluminous mode," and a "smooth and easy-to-run-through mode."

[0066] Fig. 12B shows an example in which tension is applied to the hair in addition to the component ratio control shown in Fig. 12A, thereby increasing the straightening and volume-up effects. The means for applying tension to the hair will be described later.

[0067] 12C is a diagram showing the effect of the mode when the temperature and air volume of the air discharged from the air outlet 40 are controlled in addition to the component ratio control shown in FIG. 12A. As shown in FIG. 12C, by increasing the temperature, it is possible to straighten the curls more. In addition, by straightening the curls with a high temperature and tightening them with a low temperature, the effect of increasing shine can be obtained. Furthermore, by repeatedly switching between hot and cold with a weak airflow, the effect of tidying the hair all the way to the ends can be obtained.

[0068] That is, the hot air blower 10 may further include an air temperature and air volume control unit that varies the temperature and volume of the air discharged from the air outlet 40, thereby further enhancing the effect obtained by the control of the generation volume control unit. The air temperature and air volume control unit corresponds to the air blowing control unit 212 and the heating control unit 213.

[0069] 12D shows the effect of the mode when the charge state is controlled in addition to the component ratio control shown in FIG. 12A. Controlling the charge state of the target by applying a voltage can increase or decrease the adhesion of charged particles, making it possible to more clearly distinguish the change in the finish. In other words, the heated air blower 10 may further include a voltage applying unit that applies a voltage to the target to which charged particles such as ion mist are applied.

[0070] 13 is a diagram for explaining the relationship between each mode provided in the hot air blower 10 according to this embodiment and the air temperature control and air volume control. As shown in FIG. 13, the characteristics of each mode can be emphasized by using attachments or air control.

[0071] The hot air blower 10 may further include a physical force application unit 500 that is detachable from the air outlet 40. The physical force application unit 500 applies a physical force to further enhance the effect obtained by changing the component ratio. The physical force application unit 500 corresponds to an attachment.

[0072] Fig. 14A is a diagram illustrating an attachment (physical force application unit 500) that can be attached to the heated air blower 10. Fig. 14B is an exploded view of the attachment in Fig. 14A. The attachment includes a first comb portion 501, an upper cover 502, a lower cover 503, an attachment portion 504, and a second comb portion 505. Each component of the attachment is attached using a screw portion 506. The second comb portion 505 corresponds to the bristles. The attachment includes a slit-shaped air outlet 507 in the first comb portion 501, and air drawn in through the attachment portion 504 is discharged from the air outlet 507.

[0073] For example, the attachment can be shaped to be used for both straightening and volume by changing the orientation during use. For example, when used in an upward direction to blow air to make the roots of hair stand, a volume-up effect can be achieved. On the other hand, when used in a downward direction to apply tension with the bristles, a straightening effect can be achieved.

[0074] 15 is a diagram illustrating the internal structure of a hot air blower 10 according to another embodiment. In the example shown in FIG. 15, the hot air blower 10 includes a first air intake 20a and a second air intake 20b as the plurality of air intakes 20.

[0075] 15, the hot air blower 10 includes a blower section 300 that draws in air from the first inlet 20a and discharges it from the air outlet 40. The hot air blower 10 also includes a heating section 400 that heats the air downstream of the blower section 300. The blower section 300 and the heating section 400 are provided in the first air path.

[0076] The hot air blower 10 also has a second air passage that flows the air drawn in from the second inlet 20b near the heat-generating components in the main body case to cool the components and then merges with the first air passage. The hot air blower 10 also has a third air passage that separates a portion of the air upstream of the heating unit 400 provided in the first air passage and cools the component generating unit and transports the generated components. The hot air blower 10 also has a blocking unit 50 that blocks the flow of air between the second air passage and the third air passage.

[0077] As a result, the heated air blower 10 disperses the heat caused by circuit cooling using all of the air generated by the air blower section 300. Therefore, the heated air blower 10 uses part of the dispersed air to cool and transport the ion mist generator 100, which has the effect of preventing the temperature of the ion mist generator 100 from changing and stabilizing the amount of mist generated.

[0078] 15 is provided with a leakage prevention section 60 that blocks communication between the air outlet 40 and the component outlet 30 to prevent backflow of hot air. This prevents changes in the temperature and air flow in the ion mist generating section due to the inflow of hot air, thereby achieving the effect of more stabilizing the amount of mist generated and the amount of discharge.

[0079] 16 is a diagram for explaining temperature control of the heated air blower 10 according to another embodiment. Temperature control in the heated air blower 10 maximizes the heater output of the heating unit 400 to approach the target temperature when the target temperature has not been reached. Furthermore, when the target temperature is exceeded, the heater output of the heating unit 400 is reduced. Furthermore, the target temperatures differ between the curl-straightening mode and the moisturizing mode.

[0080] That is, the hot air blower 10 according to another embodiment includes an air temperature setting unit that switches the temperature of the air discharged from the air outlet 40, an air volume setting unit that switches the air volume, and a room temperature detection unit 215a that detects the room temperature. The air blower 300 of the hot air blower 10 is controlled to have the air volume set by the air volume setting unit. The heating control unit 213 controls the heating unit 400 based on the air temperature set by the air temperature setting unit, the air volume set by the air volume setting unit, and the room temperature detected by the room temperature detection unit 215a so that the temperature of the air discharged from the air outlet 40 remains constant even if the room temperature changes.

[0081] For example, the heated air blower 10 controls the air temperature so that it does not exceed the boiling point of water, such as a maximum of 95°C, regardless of the room temperature. This prevents excessive evaporation of moisture from the hair, resulting in over-drying, and also reduces evaporation of the ion mist, making it possible to achieve a stable finish. Furthermore, in the straightening mode, the heated air blower 10 sets the temperature high to make it easier to straighten the hair, thereby preventing over-drying and achieving a stable straightening effect.

[0082] In addition, the heated air blowing device 10 is provided with an air temperature detection unit 215b that detects the air temperature near the air outlet 40, and when the air temperature exceeds a predetermined temperature, the heating unit 400 is controlled based on the temperature detected by the air temperature detection unit 215b so that the temperature remains below the predetermined temperature.

[0083] For example, when the air passage of the heated air blower 10 is blocked due to the attachment or some other obstacle, the air temperature rises and the discharged air volume decreases. Therefore, by providing the air temperature detection unit 215b near the air outlet 40, it is possible to detect the temperature rise caused by the air passage being blocked, and if the target air temperature is exceeded, the heater output is reduced and control is made to maintain the target air temperature. This allows the heated air blower 10 to control the air temperature so that it does not exceed the target temperature even with different modes, air volumes, room temperatures, etc., simply by detecting the temperature, thereby stabilizing the effect and amount of mist generated.

[0084] (Outline of processing flow of hot air blower 10) Next, the processing (hot air blowing method) in the hot air blower 10 regarding the control of the air volume and air temperature described above will be described based on the flowchart in FIG. 17. FIG. 17 is a flowchart showing an example of the processing of the hot air blower 10 according to another embodiment. The series of operations of the hot air blower 10 shown in the flowchart in FIG. 17 starts when the control device 200 is started by turning on the power, and ends when the power is turned off. In addition to turning off the power, the processing in the flowchart shown in FIG. 17 also ends when an interrupt to end the processing occurs. In addition, in the description of the flowchart below, content that is the same as that described in the description of the hot air blower 10 above will be omitted or simplified.

[0085] In step S1701, the air temperature setting unit sets a predetermined air temperature. The predetermined air temperature is, for example, a temperature set by a user operation. Then, the process proceeds to step S1702.

[0086] In step S1702, the air volume setting unit sets a predetermined air volume. The predetermined air volume is, for example, an air volume set by a user operation. Then, the process proceeds to step S1703.

[0087] In step S1703, the heating control unit 213 controls the heating unit 400 to heat based on the set air temperature. The air blow control unit 212 controls the air blowing unit 300 to blow air based on the set air volume. Then, the process proceeds to step S1704.

[0088] In step S1704, the air temperature detection unit 215b detects the temperature of the air discharged from the air outlet 40. After that, the process proceeds to step S1705.

[0089] In step S1705, the control unit 210 determines whether the detected air temperature is higher than a predetermined threshold value. Here, the predetermined threshold value is a target air temperature, for example, the temperature set by the air temperature setting unit described above.

[0090] In step S1705, if the control unit 210 determines that the detected air temperature is lower than the predetermined threshold (step S1705: YES), the process proceeds to step S1706. On the other hand, in step S1705, if the control unit 210 determines that the detected air temperature is equal to or higher than the predetermined threshold (step S1705: NO), the process proceeds to step S1708.

[0091] In step S1706, the room temperature detector 215a detects the room temperature, and then the process proceeds to step S1707.

[0092] In step S1707, the air blowing control unit 212 and the heating control unit 213 control the air blowing unit 300 and the heating unit 400 based on the detected room temperature so that the air temperature becomes the target temperature. Then, the process proceeds to step S1709.

[0093] In step S1708, the air blowing control unit 212 and the heating control unit 213 control the air blowing unit 300 and the heating unit 400 based on the detected air temperature so that the air temperature becomes the target temperature. Then, the process proceeds to step S1709.

[0094] In step S1709, the control unit 210 determines whether or not the processing of the hot air blower 10 has ended. Here, the end of the processing of the hot air blower 10 is set, for example, by turning off the power switch. In step S1709, if the control unit 210 determines that the processing of the hot air blower 10 has ended (step S1709: YES), the processing ends. On the other hand, in step S1709, if the control unit 210 determines that the processing of the hot air blower 10 has not ended (step S1709: NO), the processing returns to step S1703, and the processing from step S1703 is repeated.

[0095] In this way, the heated air blower 10 controls the heating unit 400 and the blower unit 300 based on the room temperature and air temperature, allowing appropriate processing to be performed solely by detecting temperature, without needing to detect the type of attachment, whether it is attached or detached, or whether the air volume has decreased due to an obstacle. In other words, the heated air blower 10 can control the air temperature so that it does not exceed a target temperature even with different modes, air volumes, and room temperatures, thereby stabilizing the effectiveness of the heated air blower 10 and the amount of mist generated.

[0096] The air discharge port 40 of the hot air blower 10 may also be configured as shown in Fig. 18. Fig. 18 is a diagram for explaining air discharge from the hot air blower 10 according to another embodiment. Specifically, the air discharge port 40 of the hot air blower 10 may be provided with a first diffusion section 41 that is arranged downstream of the heating section 400 and that diffuses the central part of the approximately circular heated air flowing from the heating section 400 toward the outer periphery. The air discharge port 40 of the hot air blower 10 may also be provided with a second diffusion section 42 that is arranged at the air discharge port 40 and that further diffuses the discharged air toward the outer periphery.

[0097] As a result, the heated air blower 10 can make the air temperature uniform by taking in the central air W3, which has a lower air temperature, to the outside using the first diffusion section 41. Furthermore, the heated air blower 10 can spread the air W2 over a wide area using the second diffusion section 42, thereby reducing (uniformizing) the maximum air speed. That is, by making the air temperature and air speed distributions of the high-temperature air W1 and the low-temperature air W3 more uniform, it is possible to reduce over-drying and evaporation of the ion mist due to excessive temperature, and scattering of hair due to excessive air speed, thereby making it possible to stabilize the finish.

[0098] The heated air blower 10 may also be equipped with the above-described air temperature control and at least one of the first diffusion section 41 and the second diffusion section 42, and may control the temperature so that the maximum temperature of the discharged air does not exceed the evaporation temperature of water. This makes the temperature distribution even more uniform, thereby further reducing over-drying due to excessive temperature and evaporation of ion mist, and making it possible to achieve a more stable finish.

[0099] The ion mist generator 100 may also be configured to control the applied voltage depending on the state of the Taylor cone. Figures 19A to 19C are diagrams for explaining an ion mist generator 100 according to another embodiment.

[0100] For example, the ion mist generator 100 may include a detection unit 600 that detects the shape of the Taylor cone, as shown in Fig. 19A. Furthermore, the control unit 210 of the ion mist generator 100 may adjust the magnitude of the applied voltage or the timing of stopping the applied voltage based on the shape of the Taylor cone detected by the detection unit 600. For example, the detection unit 600 may detect at least one of the position, range, and size of the Taylor cone.

[0101] 20A and 20B are graphs showing the relationship between time and the control voltage waveform and discharge current, where Fig. 20A shows the waveform without voltage control and Fig. 20B shows the waveform with voltage control.

[0102] The amount of ion mist generated increases or decreases in proportion to the cone size and the voltage at the start of discharge. Therefore, the ion mist generator 100 according to another embodiment detects changes in cone size and controls the voltage at the start of discharge to suppress changes in the amount of ion mist generated. Specifically, when the cone size changes, the time T3 until discharge starts and the discharge start voltage change, so the ion mist generator 100 controls the applied voltage to take this change into account so that it is equal to or higher than the discharge start voltage before the cone size change.

[0103] FIG. 21 is a diagram for explaining the discharge start time T3, discharge start voltage Vs, amount of ion mist generated, and voltage control method in relation to an increase or decrease in cone size.

[0104] For example, if the cone size increases due to a change in environmental temperature and humidity, the increase in cone size is captured as an image, and the detection unit 600 detects it by calculating the cone size. FIG. 22 is a diagram for explaining cone size calculation. The two diagrams at the top of FIG. 22 show examples of different cone sizes. The two diagrams at the bottom of FIG. 22 show diagrams for calculating the cone size using image processing such as edge detection. For example, compared to the diagram at the bottom left of FIG. 22, the diagram at the bottom right of FIG. 22 shows an increase in cone size. This allows the detection unit 600 to calculate the cone size, such as the amount of increase or decrease in cone size.

[0105] Furthermore, the control unit 210 calculates the discharge start time T3 and the discharge start voltage Vs from the cone size increase detected by the detection unit 600. Furthermore, the control unit 210 controls the voltage waveform so that the discharge start voltage Vs2 is equal to or greater than Vs. Specifically, the control unit 210 controls the discharge start voltage Vs2 by increasing the applied voltage or delaying the voltage increase stop time T2.

[0106] As a result, the ion mist generator 100 according to the other embodiment increases the amount of ion mist generated by strengthening the discharge to compensate for the decrease in the amount of ion mist generated as the cone size increases, thereby suppressing the change in the amount generated. Note that when the cone size is reduced, the ion mist generator 100 performs control in the opposite manner to that described above.

[0107] This allows the ion mist generator 100 to detect the state of the Taylor cone and adjust the voltage increase or decrease at the optimal timing, thereby enabling optimal control regardless of the cone size.

[0108] 19B , the ion mist generator 100 may be configured to include a current detection resistor 265, and to detect the cone shape from the discharge current detected by the current detection resistor 265. That is, the control unit 210 of the ion mist generator 100 may detect the shape of the Taylor cone based on the discharge current detected by the current detection resistor 265, and adjust the magnitude of the applied voltage or the timing to stop the applied voltage based on the shape of the Taylor cone. The value of the discharge current corresponds to a substitute characteristic value that is correlated with the cone shape.

[0109] 19C, the ion mist generator 100 may also include a supply amount adjustment unit 700 that adjusts the amount of liquid supplied, in addition to the current detection resistor 265. For example, as shown in Fig. 19C, the control unit 210 of the ion mist generator 100 may detect the cone shape from the value of the discharge current detected by the current detection resistor 265, and adjust the magnitude of the applied voltage, the timing at which the applied voltage is stopped, or the amount of liquid supplied based on this cone shape.

[0110] In this way, the ion mist generator 100 has a simple configuration and is able to detect a signal that allows easy detection of the shape of the Taylor cone, and adjust the magnitude of the applied voltage and the timing of stopping it.

[0111] Fig. 23 is a graph showing the relationship between cone size and discharge current. In phase A of Fig. 23, the cone size changes. Next, in phase B of Fig. 23, the ion mist generator 100 detects the amount of change in cone size as the amount of change in discharge current. Furthermore, in phase C of Fig. 23, the ion mist generator 100 compares the current with a reference current and controls the supply amount adjustment unit 700 so that the difference from the reference current becomes zero, thereby performing feedback control of the liquid supply amount. Note that the difference from the reference current becoming zero corresponds to the cone size becoming the reference size.

[0112] In this way, the ion mist generator 100 according to another embodiment detects the cone size and controls the amount of condensation and the strength of the discharge so that the cone size remains constant, thereby making it possible to stabilize the amount of ion mist generated.

[0113] The heated air blower 10 may further include a learning unit that learns the adjustment amounts. The control unit 210 may adjust the component amounts, component ratios, air volume, and air temperature based on learned data learned by the learning unit. This allows the heated air blower 10 to more appropriately adjust the component amounts, component ratios, air volume, and air temperature by controlling the output based on the user's hair type, usage, etc.

[0114] The heated air blower 10 may further include a communication unit for transmitting and receiving data to and from the outside. For example, the communication unit corresponds to the communication IF 240. The control unit 210 may adjust the component amounts, component ratios, air volume, and air temperature based on the data transmitted and received by the communication unit. This allows the heated air blower 10 to more appropriately adjust the component amounts, component ratios, air volume, and air temperature by controlling the output based on the user's hair type, usage, etc.

[0115] FIG. 24 is a flowchart showing the control of the hot air blower 10 having a learning function.

[0116] In step S2401, the control unit 210 acquires a user mode, which may be, for example, a mode indicating whether the learning mode is ON or OFF. Then, the process proceeds to step S2402.

[0117] In step S2402, control unit 210 determines whether learning mode is ON. If control unit 210 determines in step S2402 that learning mode is ON (step S2402: YES), the process proceeds to step S2403. On the other hand, if control unit 210 determines in step S2402 that learning mode is not ON (step S2402: NO), the process proceeds to step S2406.

[0118] In step S2403, the control unit 210 outputs the components and wind that reflect the learning data. The learning data is based on the user's satisfaction with the wind temperature and moist feeling learned by a learning unit (not shown). Then, the process proceeds to step S2404.

[0119] In step S2404, the control unit 210 acquires satisfaction level information from the user. Fig. 25 is a diagram showing examples of air temperature satisfaction level and moisturizing satisfaction level obtained from the user. For example, the control unit 210 acquires the satisfaction level from the user via the communication IF 240 or the input / output IF 230. Thereafter, the process proceeds to step S2405.

[0120] In step S2405, the control unit 210 updates the learning data based on the satisfaction level information. The learning data is updated based on example responses from the user, as shown in the example of learning data reflection in FIG.

[0121] 26 and 27A to 27B are diagrams for explaining the learning function. For example, in the example shown in FIG. 26, if a user answers that they would like the moisturizing effect to be "even more moisturizing" when using the straightening mode, the "moisturizing" and "repair" settings are increased by two levels. Also, in the example shown in FIG. 26, if a user answers that the smoothing effect is "just right" when using the straightening mode, no changes are made. Furthermore, in the example shown in FIG. 26, if a user answers that they would like the volume to be "a little more volume," the "moisturizing" and "repair" settings are decreased by one level, and the "conditioning" setting is decreased by one level.

[0122] That is, in step S2405, the control unit 210 controls the "moisturizing" and "repairing" settings to increase by one level and the "conditioning" setting to decrease by one level in the state before learning shown in Fig. 27A and the state after learning shown in Fig. 27B. Then, the process ends.

[0123] In step S2406, the control unit 210 controls the output of the normal component and wind, and then the process ends.

[0124] In another embodiment, a data server (not shown) may store data such as user preferences and hair type, as well as data relating to the relationship between user data and optimal amounts of ingredients, based on the results of multiple users using the learning mode and user surveys.

[0125] As a result, the hot air blower 10 according to the other embodiment can reflect the optimal amount of ingredients and the like from the data server by inputting the user's age, hair type, desired finish, etc. for each mode. In other words, by using the data server, the hot air blower 10 according to the other embodiment can set conditions that suit the user's preferences and hair type without repeated learning.

[0126] (Additional Notes) The above description of the embodiments discloses the following techniques.

[0127] (Technology 1) The ion mist generator of Technology 1 includes a discharge electrode, a liquid supply unit that supplies liquid to the discharge electrode, and a control unit that applies an applied voltage to the discharge electrode and controls the generation of ion mist by atomizing the liquid supplied from the liquid supply unit to the discharge electrode. The control unit causes the applied voltage to reach a predetermined voltage before the tip of a Taylor cone formed by the liquid becomes sharp as the voltage is applied and the electrostatic atomization phenomenon begins, and after the applied voltage reaches the predetermined voltage, stops the supply of energy to increase and maintain the voltage.

[0128] With this configuration, the ion mist generator of Technology 1 can increase the amount of acidic components and ion mist produced while preventing an increase in noise due to arc discharge and an increase in electrode friction.

[0129] (Technology 2) In the ion mist generator of Technology 2, in the ion mist generator described in Technology 1, the discharge electrode comprises a first columnar section, a convex curved section provided at the tip of the first columnar section, and a second columnar section at the boundary between the first columnar section and the convex curved section, the second columnar section having a larger diameter than the first columnar section. The boundary between the second columnar section and the first columnar section is a chamfered section that is chamfered in an arc shape.

[0130] This configuration makes it difficult for the Taylor cone shape at the tip of the ion mist generator of Technology 2 to change. Furthermore, by increasing the contact area between the Taylor cone and the surface area of ​​the discharge electrode at the second columnar section, the force that adheres to the discharge electrode is increased, making the Taylor cone shape less likely to change. Therefore, the ion mist generator of Technology 2 stabilizes the Taylor cone shape and enables a stable atomization amount of ion mist.

[0131] (Technology 3) In the ion mist generator of Technology 3, in the ion mist generator described in Technology 1 or 2, the liquid supply unit includes an adjusting unit that adjusts the amount of liquid supplied and a time detecting unit that detects the elapsed time from the start of operation. The liquid supply unit adjusts the amount of liquid supplied in accordance with the predetermined elapsed time.

[0132] This configuration makes it difficult for the Taylor cone shape at the tip to change in the ion mist generator of Technology 3. As a result, the ion mist generator of Technology 3 stabilizes the Taylor cone shape and makes it possible to stabilize the amount of ion mist atomized.

[0133] (Technology 4) In the ion mist generator of Technology 4, in the ion mist generator described in any one of Technologies 1 to 3, the liquid supply unit includes an adjusting means for adjusting the amount of liquid supplied, a temperature detecting unit for detecting the external environmental temperature, and a switching unit for switching the amount of ion mist required. The liquid supply unit adjusts the amount of liquid supplied in accordance with the amount of ion mist required and the external environmental temperature or humidity.

[0134] With this configuration, the ion mist generator of Technology 4 can reduce the risk of excessive or insufficient ion mist even when the supply amount fluctuates due to changes in temperature, humidity, etc. Therefore, the ion mist generator of Technology 4 can stabilize the Taylor cone shape and stabilize the amount of ion mist atomized.

[0135] (Technology 5) In the ion mist generator of Technology 5, in the ion mist generator described in any one of Technologies 1 to 4, the liquid supply unit includes an adjusting means for adjusting the amount of liquid supplied, a temperature detection unit near the electrode for detecting the temperature near the discharge electrode, and a switching unit for switching the amount of ion mist required. The liquid supply unit adjusts the amount of liquid supplied in accordance with the required amount of ion mist and the temperature or humidity near the electrode.

[0136] This configuration allows the ion mist generator of Technology 5 to control the supply amount by sensing the temperature near the discharge electrode, which affects the actual amount of liquid supplied (amount of condensation).As a result, the ion mist generator of Technology 5 stabilizes the Taylor cone shape and makes it possible to stabilize the amount of ion mist atomized.

[0137] (Technology 6) In the ion mist generator of Technology 6, in the ion mist generator described in Technology 1, the total amount of ion mist generated is 7,400 particles / cm at an air flow rate of 1.5 L / min. ３ More than / s.

[0138] With this configuration, the ion mist generator of Technology 6 generates the mist at the above-mentioned amount, and the heated air blower equipped with the ion mist generator of Technology 6 can vary the amount of ion mist applied to the target object, thereby increasing the sense of realism of the change in the finish.

[0139] (Technology 7) The ion mist generator of Technology 7 is the ion mist generator described in Technology 1, and further includes an ion adsorption section for reducing the amount of air ions emitted due to discharge when generating ion mist.

[0140] With this configuration, the ion mist generator of Technology 7 is provided with an ion adsorption section, and the position and shape of the opposing electrode are set so that particles of any size can be adsorbed, making it possible to selectively release only ion mist with large particle diameters.

[0141] (Technology 8) The ion mist generator of Technology 8 is the ion mist generator according to any one of Technologies 1 to 7, further comprising a detection unit that detects the shape of the Taylor cone. The control unit adjusts the magnitude of the applied voltage or the timing of stopping the applied voltage based on the shape of the Taylor cone detected by the detection unit.

[0142] With this configuration, the ion mist generator of Technology 8 can increase the amount of ion mist generated by strengthening the discharge to compensate for the decrease in the amount of ion mist generated as the cone size increases, thereby suppressing changes in the amount generated. Therefore, the ion mist generator of Technology 8 can achieve optimal control regardless of the cone size by detecting the state of the Taylor cone and adjusting the increase or decrease of voltage at the optimal timing.

[0143] (Technology 9) The ion mist generator of Technology 9 is the ion mist generator according to any one of Technologies 1 to 8, further comprising a current detection resistor that detects the value of the discharge current supplied to the discharge electrode. The control unit detects the shape of the Taylor cone based on the value of the discharge current detected by the current detection resistor, and adjusts the magnitude of the applied voltage or the timing to stop the applied voltage based on the shape of the Taylor cone.

[0144] With this configuration, the ion mist generator of Technology 9 can detect a signal that allows easy detection of the shape of the Taylor cone with a simple configuration, and can adjust the magnitude of the applied voltage and the timing of stopping it.

[0145] (Technology 10) The ion mist generator of Technology 10 is the ion mist generator according to Technology 9, further comprising a supply amount adjustment unit that adjusts the amount of liquid supplied. The control unit detects the shape of the Taylor cone based on the value of the discharge current detected by the current detection resistor, and adjusts the magnitude of the applied voltage, the timing at which the applied voltage is stopped, or the amount of liquid supplied based on the shape of the Taylor cone.

[0146] With this configuration, the ion mist generator of Technology 10 can detect the cone size and control the amount of condensation and the strength of discharge so that the cone size remains constant, thereby stabilizing the amount of ion mist generated.

[0147] (Technology 11) A heated air blower of Technology 11 includes an air blowing unit that draws in air through an air intake port and discharges the air to the outside through an air outlet, and a heating unit that heats the air downstream of the air blowing unit. The heated air blower of Technology 11 includes an ion mist generating unit that has the ion mist generator described in Technology 1 and a component outlet that discharges the ion mist to the outside.

[0148] With this configuration, the heated air blower of Technology 11 prevents an increase in noise due to arc discharge and an increase in electrode friction, while the ion mist generator of Technology 1 increases the amount of acidic components and ion mist produced, thereby achieving a greater effect of the components on the target object.
