Summary of the Invention

Problems to be Solved by the Invention

[0004] In the ion generator disclosed in Patent Document 1, since the dielectric breakdown between the electrodes extends over a wide range, when the discharge is strengthened to increase the ion generation amount, a high current flows, leading to the occurrence of large noise and the transition to arc discharge that causes electrode wear. Therefore, there was a limit to the voltage that could be applied. Also, to prevent the transition to arc discharge, increasing the distance between the electrodes increases the applied voltage required for discharge generation, and the device becomes larger. Therefore, there is a need for a device that can increase the generation amounts of acidic components and ion mist while preventing an increase in noise due to arc discharge and an increase in electrode friction.

[0005] The present disclosure has been made in view of the problems of such prior art. The object of the present disclosure is to provide an ion mist generator and a heating and blowing device capable of increasing the generation amount of acidic components and ion mist while preventing an increase in noise due to arc discharge and an increase in electrode friction.

The control unit causes the tip of the Taylor cone formed by the liquid to become sharp as the applied voltage is applied, reaches a predetermined voltage earlier than the start of the electrostatic atomization phenomenon, and after the applied voltage reaches the predetermined voltage, stops supplying energy for raising and maintaining the voltage.

[0007] The heating and blowing device according to the second aspect of the present disclosure includes a blowing unit that sucks air inhaled from an air inlet and discharges it to the outside from an air outlet, a heating unit that heats the air downstream of the blowing unit, the above-described ion mist generator, and an ion mist generation unit having a component outlet that discharges the ion mist to the outside.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description than necessary may be omitted. For example, a detailed description of already well-known matters or a redundant description of substantially the same configuration may be omitted. Note that the accompanying drawings and the following description are provided for 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] (Outline of the heating and blowing device 10) FIG. 1 is a schematic diagram showing the appearance of the heating and blowing device 10 according to the present embodiment. The heating and blowing device 10 is, for example, a hair dryer, and discharges heated air from the air discharge port 40. Further, the heating and blowing device 10 includes an ion mist generator 100, and discharges components such as ion mist (charged fine particle liquid) generated by the ion mist generator 100 from the component discharge port 30.

[0012] FIG. 2 is a diagram for explaining the internal structure of the heating and blowing device 10 according to the present embodiment. As shown in FIG. 2, the heating and blowing device 10 includes a blowing unit 300 that takes in air from an air intake 20 and discharges the inhaled air to the outside from an air outlet 40. Further, the heating and blowing device 10 includes a heating unit 400 that heats the air on the downstream side of the blowing unit 300. Further, the heating and blowing device 10 includes an ion mist generator 100 and a component outlet 30 that discharges the ion mist to the outside. Note that the ion mist generation unit corresponds to a configuration including the ion mist generator 100 and the component outlet 30.

[0013] As shown in FIG. 2, the component outlet 30 and the air outlet 40 are provided substantially in parallel. Thereby, the heating and blowing device 10 according to the present embodiment can quickly and in large quantities deliver the ion mist discharged from the component outlet 30 to the object along the flow of the air discharged from the air outlet 40.

[0014] (Ion Mist Generator 100) FIGS. 3 to 8 are diagrams for explaining the ion mist generator 100 according to the present embodiment. The ion mist generator 100 includes 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. Further, the ion mist generator 100 includes a counter electrode 120.

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

[0016] The high-voltage generation unit 250 includes a step-up transformer 251, a diode 252, a capacitor 253, and a protection resistor 254. In this embodiment, the output waveform of the high-voltage generation unit 250 is a pulse output. The output waveform realizes a time constant formed by the capacitor 253 and the limiting resistor 260 to be shorter than the time required for the cone-shaped change so as to make the rise of the voltage applied to the discharge electrode 110 faster than the cone-shaped change. As an example, for a cone-shaped change of about 100 μs, C = 4 pF and R = 20 MΩ are set, and the time constant C×R = 80 μs is set.

[0017] Further, the control device 200 causes the applied voltage to reach a predetermined voltage earlier than the tip of the Taylor cone formed by the liquid becomes sharp and the electrostatic atomization phenomenon starts as the applied voltage is applied. Further, after the applied voltage reaches the predetermined voltage, the control device 200 stops supplying energy for raising and maintaining the voltage.

[0018] FIG. 4, FIG. 5A, and FIG. 5B are diagrams for explaining the ion mist generator 100 according to this embodiment. FIG. 4 is a diagram schematically showing the relationship between the discharge electrode 110, the counter electrode 120, and the liquid supply unit 130. FIGS. 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 portion 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 in the longitudinal direction (the end opposite to the spherical tip portion 110a, lower end).

[0020] The counter electrode 120 is arranged to face the spherical tip portion 110a of the discharge electrode 110. Further, the counter electrode 120 is configured as a dome-shaped electrode as shown in FIGS. 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 such that the central axis of the discharge electrode 110 coincides with the central axis of the dome-shaped electrode of the counter electrode 120.

[0022] FIG. 5B is a diagram for explaining ions generated by discharge. The counter electrode 120 may be used as an adsorption part that adsorbs ions and ion mist having a particle size equal to or less than an arbitrary particle size. This can be realized, for example, by adjusting the distance to the counter electrode 120 and the dome diameter. Note that the adsorption part corresponds to an ion adsorption part.

[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 size of around 1 nm. On the other hand, charged fine particle water (ion mist) obtained by electrostatic atomization and discharge often has a large size of 3 nm or more. Since small ions are light and have a property of being easily attracted to and adsorbed by the counter electrode by an electric field, by setting the position and shape of the counter electrode 120 so that particles of any size can be adsorbed, only ion mist with a large particle size can be selectively discharged. Further, the adsorption part may be provided separately from the counter electrode, or may have a function as an adsorption part in a protrusion for causing dielectric breakdown around the counter electrode, like the counter electrode described in Patent Document 1.

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

[0025] Further, the liquid supply unit 130 may include an adjustment means for adjusting the liquid supply amount and a time detection unit for detecting the elapsed time from the start of operation, and may adjust the liquid supply amount according to a predetermined elapsed time.

[0026] As a result, the ion mist generator 100 is less likely to change the shape of the tip Taylor cone. Therefore, the ion mist generator 100 can stabilize the Taylor cone shape and the atomization amount of the ion mist.

[0027] Further, the liquid supply unit 130 may include an adjustment means for adjusting the liquid supply amount, a temperature detection unit for detecting the external environmental temperature, and a switching unit for switching the required amount of ion mist. Further, the liquid supply unit 130 may adjust the liquid supply amount according to the required amount of ion mist and the external environmental temperature or humidity.

[0028] Thereby, even when the supply amount fluctuates due to temperature and humidity changes or the like, the ion mist generator 100 can reduce the risk of the ion mist becoming excessive or insufficient. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the atomization amount of the ion mist.

[0029] Further, the liquid supply unit 130 may include an adjustment means for adjusting the liquid supply amount, an electrode-near temperature detection unit for detecting the temperature near the discharge electrode, and a switching unit for switching the required amount of ion mist. Further, the liquid supply unit 130 may adjust the liquid supply amount according to the required amount of ion mist and the temperature or humidity near the electrode.

[0030] Thereby, the ion mist generator 100 can sense the temperature near the discharge electrode, which has a great influence on the actual liquid supply amount (dew condensation amount), and control the supply amount. Therefore, the ion mist generator 100 has a more stable Taylor cone shape than when controlling the dew condensation amount according to the external environmental temperature, and can stabilize the atomization amount of the ion mist.

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

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

[0033] The Taylor cone is based on the spherical tip portion 110a, and the balance between the pulling force generated by the electrostatic force generated between the counter electrode due to the applied voltage and the force that adheres to the electrode due to the surface tension of the liquid greatly affects the shape. Therefore, it is desirable that the Taylor cone maintains a state in which the electrostatic force and the surface tension are balanced. The chamfered portion 110c has the effect of suppressing the change in the surface tension applied to the Taylor cone by cutting off the liquid adhering to the surface of the first columnar portion 110d. Further, by increasing the contact area between the Taylor cone and the surface area of the discharge electrode 110 with the second columnar portion 110b, the force in the direction of adhering to the discharge electrode 110 is increased, and the Taylor cone shape is less likely to change. Therefore, the ion mist generator 100 can stably maintain the Taylor cone shape and stabilize the atomization amount of the ion mist.

[0034] FIG. 7 is a diagram for explaining the liquid supply amount control in the ion mist generator 100 according to the present embodiment. As described above, the liquid supply unit 130 supplies the liquid for electrostatic atomization to the discharge electrode 110. For example, in the left diagram of FIG. 7, there is no Taylor cone. In this state, by increasing the amount of liquid supplied from the liquid supply unit 130, the Taylor cone is formed earlier (transition A in FIG. 7, transition from the left diagram to the middle diagram). Further, in order to maintain the state of the middle diagram of FIG. 7, it is possible by reducing the amount of liquid supplied from the liquid supply unit 130 in transition B of FIG. 7 compared to transition A.

[0035] FIG. 8 is a diagram for explaining the relationship between the amount of ion mist generated and the liquid supply amount in the ion mist generator according to the present embodiment. As shown in FIG. 8, when the amount of ion mist generated is large and the liquid supply amount is small, generally, from the principle of electrostatic atomization, the smaller the Taylor cone volume, the greater the amount of ion mist generated. Therefore, the amount of ion mist generated becomes excessive, and the risk of depletion of the Taylor cone increases. Further, when the amount of ion mist generated is small and the liquid supply amount is large, the Taylor cone becomes too large, resulting in an excessive reduction in the amount of ion mist generated and an increase in the risk of arc discharge. Therefore, in the ion mist generator 100 according to the present embodiment, the amount of ion mist generated and the liquid supply amount are adjusted so that the cone shape shown by the broken line portion in FIG. 8 becomes stable.

[0036] FIG. 9 is a block diagram showing the configuration of the control device 200 according to the present embodiment. The control device 200 may be configured as a system including a control unit 210 (CPU), a storage unit 220 (memory), and an input / output IF 230 (Interface), which is a general-purpose microcomputer. In this case, a computer program for operating the heating and blowing device 10 may be installed in the microcomputer. By executing the computer program, the microcomputer functions as a plurality of information processing circuits provided in the heating and blowing device 10. Further, the control device 200 may include a communication IF 240 that enables wired and / or wireless communication between the heating and blowing device 10 and the outside.

[0037] In the present embodiment, an example is shown in which a plurality of information processing functions provided in the control device 200 of the heating and blowing device 10 are realized by software. The control device 200 functions as a plurality of information processing circuits provided in the heating and blowing device 10 by executing a computer program.

[0038] As another configuration, the control device 200 can also configure the information processing function by a dedicated hardware for executing each information processing function, such as a system LSI (Large Scale Integration). Further, a system may be configured by individual hardware for a plurality of information processing functions. Details of the control unit 210 and the storage unit 220 will be described later.

[0039] The control unit 210 operates based on a program (not shown) stored in the storage unit 220 and executes each function provided in the control device 200. Note that the program is not limited to the form stored in the storage unit 220, and for example, it may be configured as being stored in a ROM or the like (not shown) in the heating and blowing device 10. The control unit 210 includes, as functions, a discharge electrode control unit 211, a 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. 10.

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

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

[0042] Further, as described above, the storage unit 220 may store programs for each function executed in the control unit 210. Note that the information and programs stored in the storage unit 220 may be configured as areas physically or logically divided in one storage device. Alternatively, a configuration may be adopted in which the storage unit 220 for each data is provided in a plurality of physically different storage devices.

[0043] The input / output IF230 is an interface for transmitting and receiving information to be exchanged between the control device 200 and components such as the high-voltage generation unit 250, the blower unit 300, the heating unit 400, the power switch, and the level switch provided in the heating and blower device 10.

[0044] For example, information regarding the power switch or the level switch pressed by the user is sent to the control unit 210 and / or the storage unit 220 via the input / output IF230. Also, control information from the control unit 210 to the high-voltage generation unit 250, the blower unit 300, and the heating unit 400 is sent to the high-voltage generation unit 250, the blower unit 300, and the heating unit 400 via the input / output IF230.

[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 the limiting resistor 260. FIG. 11A is a diagram for explaining the output voltage V1 of the high-voltage generation unit and the discharge current of the ion mist generator according to the present embodiment. Also, FIG. 11B is a diagram for explaining a comparative example of the voltage V2 between the discharge electrodes and the discharge current of the ion mist generator.

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

[0047] For example, in the example shown in FIG. 11A, the time from time T1 to time T3, which is the time from the start of the application of the applied voltage until the cone shape changes and discharge occurs, is 100 μs. Also, the pulses applied by the discharge electrode control unit 211 are applied at times T1 and T2 between time T1 and time T3.

[0048] Also, in this embodiment, a negative high voltage output is obtained by boosting the voltage twice at times T1 and T2. However, it is sufficient if the target voltage is reached by time T3. The number of boostings is not limited to two, and the polarity of the output voltage can be either positive or negative.

[0049] That is, in the ion mist generator 100 according to this embodiment, the tip of the Taylor cone formed by the liquid becomes sharp as the applied voltage is applied, and the applied voltage reaches a predetermined voltage earlier than the start of the electrostatic atomization phenomenon. Further, after the applied voltage reaches the predetermined voltage, the voltage is increased and the energy supply for maintaining it is stopped. Thereby, the ion mist generator 100 according to this embodiment can increase the generation amounts of acidic components and ion mist while preventing an increase in noise due to arc discharge and an increase in electrode wear.

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

[0051] As a conventional configuration, when a DC voltage (direct current voltage) smoothed by a large-capacity output capacitor is applied, compared with the case of FIG. 11B, the voltage during discharge is low and the voltage does not easily drop even after the start of discharge (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, there are restrictions on the voltage that can be applied. Further, if the distance between the electrodes is increased to prevent arc discharge, the required voltage also increases, resulting in problems such as an increase in the size of the device and an increase in noise.

[0052] On the other hand, the ion mist generator 100 according to this embodiment applies a high-voltage pulse voltage before the cone shape changes, instead of a DC voltage, so that the voltage at the start of discharge is increased, and while strengthening the discharge, arc discharge can be prevented. Thereby, the ion mist generator 100 can increase the generation amounts of acidic components and ion mist without causing an increase in the size of the device.

[0053] The air supply control unit 212 controls the air volume of the air supply unit 300 provided in the heating and air supply device 10. For example, the heating and air supply device 10 according to the present embodiment may be provided with air volume modes of weak wind, medium wind, and strong wind.

[0054] The heating control unit 213 controls the calorific value of the heating unit 400 provided in the heating and air supply device 10. For example, the heating control unit 213 of the heating and air supply device 10 according to the present embodiment controls the heating unit 400 so that the temperature of the air discharged from the air discharge port 40 becomes a predetermined temperature.

[0055] The component generation control unit 214 controls the generation amount of the ion mist generated by the ion mist generator 100. Further, the component generation control unit 214 may have a function of controlling the generation amounts of the components generated by the ion generation unit, the acidic component generation unit, and the transition metal fine particle 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 an electrode vicinity temperature detection unit 215c.

[0057] The room temperature detection unit 215a includes a mechanism for detecting the room temperature. The air temperature detection unit 215b detects the temperature of the air discharged from the heating and air supply device 10. Further, the electrode vicinity temperature detection unit 215c is provided near the ion mist generator 100 and detects the temperature near the electrode.

[0058] (Other embodiments) As described above, the present embodiment has been described, but the embodiment is not limited to these, and various modifications are possible within the scope of the gist of the embodiment. Also, it is possible to combine some or all of various embodiments to form a new embodiment.

[0059] In the heating and blowing device 10 according to the above-described embodiment, a configuration including the ion mist generator 100 is shown. For example, the heating and blowing device 10 may be configured to include, in addition to the ion mist generator 100, a component generator having at least one of an ion generation unit, an acidic component generation unit, or a transition metal fine particle generation unit. Further, this component generator may generate at least two or more components of ion mist, ions, acidic components, or transition metal fine particles.

[0060] As a result, the heating and blowing device 10 can discharge ion mist, ions, acidic components, or transition metal fine particles without inhibiting the discharge of each component. Therefore, the heating and blowing device 10 can reach the hair without the ion mist, ions, acidic components, or transition metal fine particles being deactivated in the air, and can further enhance the hair care effect.

[0061] Further, the discharge directions of the plurality of component discharge ports of the component generator and the air discharge port 40 may be provided substantially parallel to each other. As a result, the components discharged from the heating and blowing device 10 can quickly and in large quantities reach the object by riding on the flow of the air discharged from the heating and blowing device 10.

[0062] Further, the plurality of component discharge ports of the heating and blowing device 10 may be configured to be spaced apart in a substantially circumferential direction of the air discharge port 40. As a result, the heating and blowing device 10 can stably supply the components to the object regardless of the way the air is applied.

[0063] Further, it may further include a generation amount control unit that controls two or more component generators. Further, the generation amount control unit may vary the component ratio generated by the component generator by making the component generation amount variable by at least two or more independent controls. The heating and blowing device 10 can realize an appropriate finish according to the usage mode for the object. Note that the generation amount control unit corresponds to the component generation control unit 214.

[0064] Further, in the ion mist generator 100, the ion mist generation amount is at least 7400 pieces / cm 3 / s or more, more preferably 37,000 pieces / cm 3 / s or more (at an air flow rate of 1.5 L / min) is preferable. Generally, since the amount of atomization based on the principle of electrostatic atomization has a smaller number of particles compared to the amount of ion generation by discharge, even if the amount of mist generation is variable with a small amount of mist, it is difficult to significantly change the finish, or there is a problem of deteriorating the finish due to a decrease in mist. By setting the amount of mist generation as described above in the present embodiment, the heating and blowing device 10 can enhance the feeling of change in the finish by making the amount of ion mist applied to the object variable.

[0065] Figures 12A to 12D are diagrams for explaining each mode provided in the heating and blowing device 10 according to the present 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 hair as the object. For example, as shown in Figures 12A to 12D, different finishes correspond to a "moist and neat mode", a "mode for straightening curls", a "fluffy volume-up mode", and a "smooth and easy-to-run-through mode".

[0066] Figure 12B shows an example where, in addition to the component ratio control shown in Figure 12A, by applying tension to the hair, the effect of increasing curl elongation and volume-up is increased. The means for applying tension to the hair will be described later.

[0067] Figure 12C is a diagram showing the effect of the mode when, in addition to the component ratio control shown in Figure 12A, the temperature and air volume of the air discharged from the air outlet 40 are controlled. As shown in Figure 12C, by making the temperature higher, it becomes possible to stretch the curls more. Also, by stretching the curls at a high temperature and tightening them at a low temperature, an effect of increasing gloss can be obtained. Furthermore, by repeatedly performing warm and cold with a weak wind, an effect of gathering the hair tips can be obtained.

[0068] That is, the heating and blowing device 10 may further include a wind temperature and air volume control unit that makes the wind temperature and air volume of the air discharged from the air outlet variable and further enhances the effects obtained by the control of the generation amount control unit. Note that the wind temperature and air volume control unit corresponds to the blowing control unit 212 and the heating control unit 213.

[0069] FIG. 12D is a diagram showing the effects of the mode when the charging state is controlled in addition to the component ratio control shown in FIG. 12A. By controlling the charging state of the object by applying a voltage, it is possible to make the change in the finish more prominent by increasing or decreasing the adhesion of charged particles. That is, the heating and blowing device 10 may further include a voltage application unit that applies a voltage to an object to which charged particles such as ion mist are applied.

[0070] FIG. 13 is a diagram for explaining the relationship between each mode provided in the heating and blowing device 10 according to the present embodiment and the wind temperature control and the air volume control. As shown in FIG. 13, it is possible to make the characteristics of each mode prominent by attachment or wind control.

[0071] The heating and blowing device 10 may further include a physical force application unit 500 that is detachable from the air outlet 40. The physical force application unit 500 further enhances the effects obtained by changing the component ratio by applying a physical force. Note that the physical force application unit 500 corresponds to an attachment.

[0072] FIG. 14A is a diagram for explaining an attachment (physical force application unit 500) that can be attached to the heating and blowing device 10. FIG. 14B is an exploded view of the attachment in FIG. 14A. The attachment includes a first comb part 501, an upper cover 502, a lower cover 503, a mounting part 504, and a second comb part 505. Further, each component of the attachment is attached by a screw part 506. Note that the second comb part 505 corresponds to bristles. The attachment includes a slit-shaped air outlet 507 in the first comb part 501 and discharges the air inhaled from the mounting part 504 from the air outlet 507.

[0073] For example, by changing the orientation during use, the attachment can be used for both kink stretching and volume increase. For example, in the case of blowing air upward to raise the roots of the hair, a volume increase effect can be obtained. Also, by turning it downward and applying tension with the bristles, an effect of stretching the target kink can be obtained.

[0074] FIG. 15 is a diagram for explaining the internal structure of the heating and blowing device 10 according to another embodiment. In the example shown in FIG. 15, the heating and blowing device 10 includes a first suction port 20a and a second suction port 20b as a plurality of suction ports.

[0075] Also, in the example shown in FIG. 15, the heating and blowing device 10 includes a blowing unit 300 that discharges the air inhaled from the first suction port 20a from the air discharge port 40. Further, the heating and blowing device 10 includes a heating unit 400 that heats the air on the downstream side of the blowing unit 300. The blowing unit 300 and the heating unit 400 are provided in the first air passage.

[0076] Moreover, the heating and blowing device 10 includes a second air passage that flows the air inhaled from the second suction port 20b near the heat-generating components in the main body case to cool the components and then merges into the first air passage. Further, the heating and blowing device 10 includes a third air passage that separates a part of the air from upstream of the heating unit 400 provided in the first air passage to cool the component generation unit and convey the generated components. Also, the heating and blowing device 10 includes a blocking unit 50 that blocks the air flow between the second air passage and the third air passage.

[0077] Thereby, in the heating and blowing device 10, the heat due to circuit cooling is dispersed by all of the air generated by the blowing unit 300. Therefore, the heating and blowing device 10 can use a part of the dispersed air for cooling and conveying the ion mist generator 100, so that the temperature of the ion mist generator 100 hardly changes and a stable generation amount can be obtained.

[0078] In addition, the heating and blowing device 10 shown in FIG. 15 is provided with a leakage prevention part 60 that blocks the space between the air discharge port 40 and the component discharge port 30 to prevent the backflow of warm air. As a result, the heating and blowing device 10 can prevent changes in the temperature of the ion mist generation part and the air flow due to the inflow of warm air, and thus an effect that the amount of mist generation and discharge becomes more stable can be obtained.

[0079] FIG. 16 is a diagram for explaining the temperature control of the heating and blowing device 10 according to another embodiment. In the temperature control of the heating and blowing device 10, when the target temperature is not reached, the heater output of the heating part 400 is maximized to approach the target temperature. Further, when the target temperature is exceeded, the heater output of the heating part 400 is decreased. Also, in the curly hair stretching mode and the moist mode, the target temperatures are different.

[0080] That is, the heating and blowing device 10 according to another embodiment includes an air temperature setting part that switches the air temperature of the air discharged from the air discharge port 40, an air volume setting part that switches the air volume, and a room temperature detection part 215a that detects the room temperature. Further, the blowing part 300 of the heating and blowing device 10 is controlled to have the air volume set by the air volume setting part. Also, the heating control part 213 controls the heating part 400 based on the air temperature set by the air temperature setting part, the air volume set by the air volume setting part, and the room temperature detected by the room temperature detection part 215a so that the air temperature discharged from the air discharge port 40 remains constant even when the room temperature changes.

[0081] For example, the heating and blowing device 10 is controlled so that the air temperature does not exceed the boiling point of water, such as 95 degrees at maximum, at any room temperature. As a result, the heating and blowing device 10 can prevent an over-dried state in which the moisture of the hair is excessively evaporated, and further reduce the evaporation of the ion mist, so that the finish can be stabilized. Also, in the curly hair stretching mode, the heating and blowing device 10 can set the temperature high so that the curls are likely to stretch, and while preventing over-drying and the like, the curly hair stretching effect can also be stabilized.

[0082] Further, the heating and blowing device 10 includes a wind temperature detection unit 215b that detects the wind temperature in the vicinity of the air discharge port 40. When the wind temperature exceeds a predetermined temperature, the heating unit 400 is controlled based on the temperature detected by the wind temperature detection unit 215b so as to be equal to or lower than the predetermined temperature.

[0083] For example, when the attachment is attached or the air passage is blocked by some obstacle in the heating and blowing device 10, the wind temperature rises when the discharge air volume decreases. Therefore, by providing the wind temperature detection unit 215b near the air discharge port 40, it is possible to detect a temperature rise due to the blockage of the air passage, and when the target wind temperature is exceeded, the heater output can be reduced and controlled to reach the target wind temperature. As a result, the heating and blowing device 10 can be controlled so that the wind temperature does not exceed the target temperature even in different modes, air volumes, room temperatures, etc. only by temperature detection, and the effect and the amount of mist generation are stabilized.

[0084] (Schematic of the processing flow of the heating and blowing device 10) Next, regarding the control of the above-described air volume and wind temperature, the processing (heating and blowing method) in the heating and blowing device 10 will be described based on the flowchart of FIG. 17. A series of operations of the heating and blowing device 10 shown in the flowchart of FIG. 17 are started when the control device 200 is activated by turning on the power, and the processing ends when the power is turned off. Also, the flowchart shown in FIG. 17 ends the processing not only when the power is turned off but also by an interrupt for ending the processing. In the following description of the flowchart, the same content as that described in the above description of the heating and blowing device 10 will be omitted or simplified.

[0085] In step S1701, the wind temperature setting unit sets a predetermined wind temperature. The predetermined wind temperature is, for example, the temperature set by the user's operation. Thereafter, the processing 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, the air volume set by the user's operation. Thereafter, the processing proceeds to step S1703.

[0087] In step S1703, the heating control unit 213 heats the heating unit 400 based on the set air temperature. Also, the air blowing control unit 212 causes air to be blown from the air blowing unit 300 based on the set air volume. Thereafter, the process proceeds to step S1704.

[0088] In step S1704, the air temperature detection unit 215b detects the air temperature of the air discharged from the air outlet 40. Thereafter, 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 the target air temperature, for example, the temperature set by the above-described air temperature setting unit.

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

[0091] In step S1706, the room temperature detection unit 215a detects the room temperature. Thereafter, 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 as to achieve the target air temperature. Thereafter, 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 as to achieve the target air temperature. Thereafter, the process proceeds to step S1709.

[0094] In step S1709, the control unit 210 determines whether the processing of the heating and blowing device 10 has ended. Here, the end of the processing of the heating and blowing device 10 is set, for example, by turning off the power switch. In step S1709, when the control unit 210 determines that the processing of the heating and blowing device 10 has ended (step S1709: YES), the processing ends. On the other hand, in step S1709, when the control unit 210 determines that the processing of the heating and blowing device 10 has not ended (step S1709: NO), the processing returns to step S1703, and the processing from step S1703 is repeatedly executed.

[0095] In this way, the heating and blowing device 10 can perform appropriate processing only by temperature detection without detecting the type of attachment, attachment and detachment, or a decrease in the air volume due to an obstacle by controlling the heating unit 400 and the blowing unit 300 based on the room temperature and the air temperature. That is, the heating and blowing device 10 can be controlled so that the air temperature does not exceed the target temperature even in different modes, air volumes, and room temperatures only by temperature detection, and the effect and the amount of mist generation of the heating and blowing device 10 can be stabilized.

[0096] Further, the air discharge port 40 of the heating and blowing device 10 may have a configuration as shown in FIG. 18. Specifically, the air discharge port 40 of the heating and blowing device 10 may be disposed downstream of the heating unit 400 and include a first diffusion unit 41 that diffuses the air at the center of the substantially circular heating air flowing from the heating unit 400 toward the outer peripheral portion. Further, the air discharge port 40 of the heating and blowing device 10 may be disposed at the air discharge port 40 and include a second diffusion unit 42 that further diffuses the discharged air toward the outer peripheral portion.

[0097] As a result, the heating and blowing device 10 can equalize the air temperature by taking in the air W3 near the center with a low air temperature to the outside by the first diffusion part 41. Further, the heating and blowing device 10 can spread the air W2 over a wide range and reduce (equalize) the maximum wind speed by the second diffusion part 42. That is, by making the air temperature and the wind speed distribution closer to being more uniform with respect to the high-temperature air W1 and the low-temperature air W3, it is possible to reduce over-drying due to excessive temperature, evaporation of ion mist, and scattering of hair due to excessive wind speed, and to stabilize the finish.

[0098] Further, the heating and blowing device 10 may include the above-described air temperature control and the first diffusion part 41 and / or the second diffusion part 42, and may perform temperature control so that the maximum temperature of the discharged air does not exceed the evaporation temperature of water. As a result, by making the temperature distribution closer to being more uniform, it is possible to further reduce over-drying due to excessive temperature and evaporation of ion mist, and to make the finish more stable.

[0099] Further, the ion mist generator 100 may use a configuration that controls the applied voltage according to the state of the Taylor cone. FIGS. 19A to 19C are diagrams for explaining an ion mist generator according to another embodiment.

[0100] For example, as shown in FIG. 19A, the ion mist generator 100 may include a detection part 600 that detects the shape of the Taylor cone. Further, the control part of the ion mist generator 100 may adjust the magnitude of the applied voltage or the stop timing of the applied voltage based on the shape of the Taylor cone detected by the detection part 600. For example, the detection part 600 may detect the position, range, and / or size of the Taylor cone.

[0101] FIGS. 20A and 20B are graphs showing the relationship between time, the control voltage waveform, and the discharge current. Note that FIG. 20A shows the case without voltage control, and FIG. 20B shows the waveform in the case 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 other embodiments suppresses changes in the amount of ion mist generated by detecting changes in the cone size and controlling the voltage at the start of discharge. Specifically, when the cone size changes, since the time T3 until the start of discharge and the discharge start voltage change in the ion mist generator 100, the control is performed so that the applied voltage is equal to or higher than the discharge start voltage before the cone size change, including this change amount.

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

[0104] For example, when the cone size increases due to changes in environmental temperature and humidity, an image of the increase in the cone size is taken, and the detection unit 600 detects it by calculating the cone size. FIG. 22 is a diagram for explaining the calculation of the cone size. The upper two diagrams in FIG. 22 show examples of different cone sizes. Also, the lower two diagrams in FIG. 22 show diagrams for calculating the cone size using image processing such as edge detection. For example, with respect to the lower left diagram in FIG. 22, it can be recognized from the lower right diagram in FIG. 22 that the cone size is increasing. Thereby, the detection unit 600 performs calculations of the cone size such as the amount of increase or decrease in the cone size.

[0105] Also, the control unit 210 calculates the discharge start time T3 and the discharge start voltage Vs from the amount of increase in the cone size detected by the detection unit 600. Further, the control unit 210 controls the voltage waveform so that the discharge start voltage Vs2 ≥ Vs. Specifically, the control unit 210 controls the discharge start voltage Vs2 by increasing the applied voltage or delaying the voltage rise stop time T2.

[0106] As a result, in the ion mist generator 100 according to other embodiments, as the cone size increases and the amount of ion mist generation decreases, the discharge can be strengthened to increase the amount of ion mist generation and suppress the change in the generation amount. In the case of a decrease in the cone size, the ion mist generator 100 performs control opposite to the above.

[0107] As a result, the ion mist generator 100 can perform optimal control regardless of the cone size by detecting the state of the Taylor cone and adjusting the increase and decrease of the voltage at the optimal timing.

[0108] Further, as shown in FIG. 19B, the ion mist generator 100 may include a current detection resistor 265 and may be configured to detect the cone shape from the discharge current detected by the current detection resistor 265. Note that the value of the discharge current corresponds to a substitute characteristic value correlated with the cone shape.

[0109] Further, as shown in FIG. 19C, the ion mist generator 100 may include a supply amount adjustment unit 700. For example, as shown in FIG. 19C, 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 based on this cone shape, adjust the magnitude of the applied voltage, the stop timing of the applied voltage, or the liquid supply amount.

[0110] In this way, the ion mist generator 100 has a simple configuration, can detect a signal that easily detects the shape of the Taylor cone, and can adjust the magnitude of the applied voltage and the stop timing.

[0111] FIG. 23 is a graph showing the relationship between the cone size and the 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 the cone size as the amount of change in the discharge current. Further, in phase C of FIG. 23, the ion mist generator 100 compares with the reference current and controls the supply amount adjuster 700 so that the difference from the reference current becomes zero, and performs 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] As described above, the ion mist generator 100 according to another embodiment can stabilize the ion mist generation amount by detecting the cone size so that the cone size becomes constant and controlling the dew condensation amount and the discharge intensity.

[0113] Further, the heating and blowing device 10 may further include a learning unit that learns the adjustment amount. The control unit 210 may adjust the component amount, the component ratio, the air volume, and the air temperature based on the learned data learned by the learning unit. Thereby, the heating and blowing device 10 can more appropriately adjust the component amount, the component ratio, the air volume, and the air temperature by performing output control based on the user's hair quality, usage method, and the like.

[0114] Further, the heating and blowing device 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 amount, the component ratio, the air volume, and the air temperature based on the data transmitted and received by the communication unit. Thereby, the heating and blowing device 10 can more appropriately adjust the component amount, the component ratio, the air volume, and the air temperature by performing output control based on the user's hair quality, usage method, and the like.

[0115] FIG. 24 is a flowchart showing the control of the heating and blowing device 10 having a learning function.

[0116] In step S2401, the control unit 210 acquires the user mode. The user mode is, for example, a mode indicating ON or OFF of the learning mode. After that, the process proceeds to step S2402.

[0117] In step S2402, the control unit 210 determines whether the learning mode is ON. In step S2402, when the control unit 210 determines that the learning mode is ON (step S2402: YES), the process proceeds to step S2403. On the other hand, in step S2402, when the control unit 210 determines that the 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 the wind that reflect the learning data. The learning data is based on the wind temperature and the satisfaction degree of the moist feeling of the user learned in a learning unit (not shown). After that, the process proceeds to step S2404.

[0119] In step S2404, the control unit 210 acquires the satisfaction information from the user. FIG. 25 is a diagram showing examples of the wind temperature satisfaction and the moist feeling satisfaction obtained from the user. For example, the control unit 210 acquires the satisfaction from the user via the communication IF240 and the input / output IF230. After that, the process proceeds to step S2405.

[0120] In step S2405, the control unit 210 updates the learning data based on the satisfaction information. The update of the learning data is performed based on an example of the user's answer as shown in the example of reflecting the learning data in FIG. 25.

[0121] Figures 26 and 27A to 27B are diagrams for explaining the learning function. For example, in the example shown in FIG. 26, when, as a response during the use of the curl elongation mode, there is a response of "wanting to be even more moist" for the moist feeling, "moisture" and "repair" are increased by two steps. Also, in the example shown in FIG. 26, when, as a response during the use of the curl elongation mode, there is a response of "just right" for the curl elongation, there is no change. Further, in the example shown in FIG. 26, when there is a response of "increase the volume a little more" for the volume, control is performed so that "moisture" and "repair" are decreased by one step and "conditioning" is decreased by one step.

[0122] That is, in step S2405, the control unit 210 controls so that in the state before learning in FIG. 27A and after learning in FIG. 27B, "moisture" and "repair" increase by one step and "conditioning" decreases by one step. Then, the process ends.

[0123] In step S2406, the control unit 210 controls to output normal components and air. Then, the process ends.

[0124] Also, in another embodiment, a data server (not shown) may store data such as the user's preferences and hair quality, and relationship data between the user data and the optimal component amount based on the learning mode usage results and user questionnaires of a large number of people.

[0125] Thereby, the heating and blowing device 10 according to another embodiment can reflect the optimal component amount and the like from the data server by inputting the user's age, hair quality, desired finish, etc. for each mode. That is, by using the data server, the heating and blowing device 10 according to another embodiment can be set to conditions suitable for the user's preferences and hair quality without repeated learning.

[0126] (Supplementary Note) From the description of the above embodiments, the following technology is disclosed.

[0127] (Technology 1) A discharge electrode, a liquid supply unit that supplies liquid to the discharge electrode, a control unit that applies an applied voltage to the discharge electrode and controls the generation of an ion mist by atomization of the liquid supplied from the liquid supply unit to the discharge electrode, and comprises: The control unit causes the tip of the Taylor cone formed by the liquid to become sharp as the applied voltage is applied, reaches a predetermined voltage earlier than the start of the electrostatic atomization phenomenon, raises the voltage after the applied voltage reaches the predetermined voltage, and stops the energy supply for maintaining the voltage, an ion mist generator.

[0128] With this configuration, the ion mist generator 100 can increase the amount of acidic components and ion mist while preventing an increase in noise due to arc discharge and an increase in electrode friction.

[0130] With this configuration, the ion mist generator 100 is less likely to change the shape of the Taylor cone at the tip. Also, by increasing the contact area between the Taylor cone and the surface area of the discharge electrode 110 at the second columnar portion, the force in the direction of sticking to the discharge electrode 110 is increased, and the Taylor cone shape is less likely to change. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the atomization amount in the ion mist.

[0131] (Technology 3) The liquid supply unit includes adjustment means for adjusting the liquid supply amount and a time detection unit for detecting the elapsed time from the start of operation, and adjusts the liquid supply amount according to a predetermined elapsed time, the ion mist generator according to Technology 1 or 2.

[0132] With this configuration, the ion mist generator 100 is less likely to have a changing Taylor cone shape at the tip. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the atomization amount in the ion mist.

[0134] With this configuration, the ion mist generator 100 can reduce the risk of the ion mist being excessive or insufficient even when the supply amount fluctuates due to temperature and humidity changes or the like. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the atomization amount in the ion mist.

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

[0136] With this configuration, the ion mist generator 100 can sense the temperature near the discharge electrode that affects the actual liquid supply amount (dew condensation amount) and control the supply amount. Therefore, the ion mist generator 100 has a stable Taylor cone shape and can stabilize the atomization amount in the ion mist.

[0137] (Technology 6) The ion mist generator according to Technology 1, wherein the total amount of the generated ion mist is more than 7400 pieces / cm3 / s at a wind flow rate of 1.5 L / min.

[0138] With this configuration, the ion mist generator 100 can enhance the perception of finish changes by making the amount of ion mist applied to the object variable by setting the mist generation amount as described above, so that the heating and blowing device 10 can vary the amount of ion mist applied to the object.

[0139] (Technology 7) The ion mist generator according to Technology 1, further comprising an ion adsorption part for reducing the discharge amount of air ions generated during the discharge when generating the ion mist.

[0140] With this configuration, the ion mist generator 100 is provided with an ion adsorption part, and by setting the position and shape of the counter electrode 120 so that particles of any size are adsorbed, only the ion mist with a large particle diameter can be selectively discharged.

The ion mist generator according to any one of Technologies 1 to 7.

[0142] With this configuration, as the cone size increases and the ion mist generation amount decreases, the ion mist generator 100 can increase the ion mist generation amount by strengthening the discharge and suppress the change in the generation amount. Therefore, the ion mist generator 100 can perform optimal control regardless of the cone size by detecting the state of the Taylor cone and adjusting the increase and decrease of the voltage at the optimal timing.

[0143] (Technology 9) Further comprising a current detection resistor for detecting the value of the discharge current supplied to the discharge electrode, The control part 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 stop timing of the applied voltage based on the shape of the Taylor cone. The ion mist generator according to any one of Technologies 1 to 8.

[0144] With this configuration, the ion mist generator 100 can detect a signal that is easy to detect the shape of the Taylor cone with a simple configuration, and can adjust the magnitude of the applied voltage and the stop timing.

[0145] (Technology 10) Further comprising a supply amount adjustment unit for adjusting the supply amount of the liquid, 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 stop timing of the applied voltage, or the supply amount of the liquid based on the shape of the Taylor cone. The ion mist generator according to Technology 9.

[0146] With this configuration, the ion mist generator 100 can detect the cone size so that the cone size becomes constant, and can stabilize the ion mist generation amount by controlling the dew condensation amount and the discharge strength.
