  The present invention relates to a beauty apparatus that gives a predetermined beauty effect to a user's skin.

  Note that the term “skin” used in conjunction with “skin” as a target for providing a cosmetic effect in the present invention is treated as synonymous with “skin” on the body surface layer including not only the body surface but also subcutaneous tissue such as subcutaneous fat. Yes.

  In addition, the “stimulus imparting part” for imparting irritation to the skin in the present invention refers to those that give irritation in a general sense in the skin, such as contact, as well as external energization such as energization of a weak current to the skin. Those that cause an action on the skin that cannot be perceived by humans even if applied from the point of view are included in the “stimulus applying part” if they are accompanied by a mechanism that is intentionally applied to the skin.

  Beauty devices that perform various operations related to predetermined beauty / skin on the skin (skin) of the user's face, etc., are simple functions that are used at home, low-output ones, and multi-functions that are used for business purposes. Various types are used, including those with high output. Among these beauty devices, the simple ones used at home include those that cool or heat the skin, those that apply suction to the skin, those that apply steam or mist to the skin, and irradiate the skin with light. Doing things, transmitting ultrasonic vibrations to the skin, applying weak current to the skin to perform iontophoresis (iontophoresis), or applying weak current to the skin to remove fine dirt (cleansing) Things are generally used.

  Among these, those in which a weak current is passed through the skin, that is, energized, are known that can change the temperature of the electrode portion that contacts the skin in the energized state, thereby giving the skin a warm or cool feeling. As an example of such a conventional beauty device that gives a warm feeling to the skin, an apparatus disclosed in Japanese Patent Application Laid-Open No. 2011-41705 has been proposed by the present applicant. Moreover, there exists an apparatus shown by Unexamined-Japanese-Patent No. 2006-101410 as an example of what can selectively give one of warm feeling and cold feeling to skin.

JP 2011-41705 A Japanese Patent Laid-Open No. 2006-101410

  The conventional beauty apparatus has a configuration shown in each of the above-mentioned patent documents. In such an apparatus, the current-carrying electrode is heated or cooled together with the current-carrying for introducing ions into the skin. In use, the electrode protruding from the main body of the device is usually applied to the skin to be cosmetics such as the face, and then the skin is energized, the electrode is heated to warm the skin, or the electrode is cooled. Thus, the user performs an operation for cooling the skin.

  With such a conventional device, the electrode is brought into contact with the skin and energization for ion introduction is performed on the skin. At the same time, when the electrode is heated to warm the skin, penetration of other ionic components into the skin can be promoted. It is known that the energization of the skin and the application of heat are often adopted as one of the main operation modes of the apparatus.

  However, if the skin is energized and heated at a time when the temperature is high during summer, for example, when heat is difficult to dissipate from the skin, or when the skin is sufficiently warm, such as after a bath, the effect of ion introduction is Although it increases, there is a problem that the skin becomes hot and the skin becomes hot, which may lead to discomfort for the user.

  On the other hand, an apparatus having a function of warming the skin as well as a function of cooling the skin can apply the cooled electrode to the skin to cool the heat of the previously warmed skin and obtain a comfortable feeling. However, after the execution of the energization and heat application mode for ion introduction is stopped, it is necessary to select and execute the mode for cooling the skin by the user's operation again, or in the case of a device where the part for heating the skin and the part for cooling are different There is a problem that a troublesome operation is required, for example, the user needs to change the device and touch the skin to cool the skin.

  The present invention has been made in order to solve the above-mentioned problems, and a temperature change of hot and cold can be alternately generated in one heat transfer section, and the thermal stimulation to the skin is performed independently or simultaneously with the operation related to the application of other stimulation. The purpose is to provide a beauty device that can be applied continuously and can be applied comfortably, can be used comfortably in any situation, and can achieve the maximum effect related to beauty. .

  A cosmetic device disclosed by the present invention includes a main body held by a user, and a stimulus applying unit that is provided integrally with the main body and can apply a predetermined stimulus related to beauty to the user's skin. In the beauty device for applying the predetermined stimulus to the user's skin by bringing the stimulus applying part close to or in contact with the user's skin, the material is formed of a material having thermal conductivity, and the ambient temperature of the user Is changed to a different temperature and applies a stimulus based on the temperature to the user's skin. A heat source unit that heats and cools the unit, and a control unit that controls energization to the heat source unit and can adjust the heating and cooling state of the heat transfer unit by the heat source unit. The contacted heat transfer section is higher than the ambient temperature. A state where warm to first predetermined temperature, in which is the state where cool to a second predetermined temperature lower than the ambient temperature to occur alternately, executes a control of the heat source unit.

  As described above, according to the disclosure of the present invention, the heat transfer unit that changes the temperature and applies the stimulus based on the temperature is provided as the stimulus applying unit that gives the skin the stimulus related to the beauty, and the energization by the control unit A heat source unit for heating and cooling the heat transfer unit based on the control is provided, and with the heat transfer unit approaching or contacting the user's skin, the control unit controls the temperature of the heat source unit. The state where the heat transfer unit is warmed and the state where the heat transfer unit is cooled alternately occur, and the heat transfer unit continuously applies warm and cold stimuli to the skin. A cold stimulus will be applied subsequently to the stimulus, and the discomfort that may occur when the preceding warm stimulus is applied to the skin can be mitigated and suppressed by the subsequent application of the cold stimulus. Effects of stimuli associated with temperature changes and others given at the same time Synergy with stimulation from the stimulating unit, a reasonably appropriate can be given to the skin. In addition, when a heat stimulus and a cold stimulus are alternately applied to the skin in the heat transfer section, for example, a switching operation by a user in each operation mode for performing a warm stimulus and a cold stimulus, The device operation for exchanging each stimulus applying portion for applying the stimulus and making it contact with the skin becomes unnecessary, the stimulus applying state can be easily obtained, and the user does not have to feel troublesome operation.

  In addition, by repeating alternating application of warm and cold stimuli to the skin, the effect of promoting blood circulation and metabolism on the skin by warm stimuli and the effect of tightening the skin by cold stimuli on the skin for each stimulus. Not only the effect but also the effect of blood circulation promotion and fatigue recovery based on alternating heating and cooling are given to the muscles directly under the skin, and it can also obtain a tension relaxation effect similar to when massaging the muscles, especially in the face With the synergistic effect on muscles, you can expect the same lift-up action as face massage.

  Further, in the beauty device disclosed by the present invention, the control unit has the same length of the warm period that is higher than the ambient environment temperature in the heat transfer unit and the cool period that is lower than the ambient environment temperature as necessary. As described above, control of the heat source unit is executed.

  As described above, according to the disclosure of the present invention, the control unit controls the heating and cooling state of the heat transfer unit by the heat source unit, the heat transfer unit temperature is higher than the ambient environment temperature, and the heat transfer unit temperature is the ambient temperature. By making the cold period lower than the environmental temperature have the same length in time, the balance between the warm stimulus and the cold stimulus is balanced, and the effect on the skin by one of the more given stimuli is less. It is possible to prevent the effect on the skin due to the irritation of the skin from being obscured and becoming inconspicuous, and the user can feel the amount of warm and cold stimulation given to the skin from the heat transfer part evenly, An appropriate stimulus application state can be obtained without causing a sense of incongruity due to a difference in the amount of stimulation or a feeling of excessive or insufficient stimulation.

  Further, in the beauty device disclosed by the present invention, the degree of temperature increase per unit time of the heat transfer unit in a state where the control unit heats the heat transfer unit cools the heat transfer unit as necessary. The control of the heat source unit is executed so as to be larger than the degree of temperature decrease per unit time of the heat transfer unit.

  Thus, according to the disclosure of the present invention, the control unit controls the heating and cooling states of the heat transfer unit by the heat source unit, and the temperature increase degree of the heat transfer unit in the state of heating the heat transfer unit As the temperature rise of the heat transfer section in the cooling state is larger than the degree of temperature decrease, the temperature rise of the heat transfer section is abrupt change, and the first predetermined temperature is reached in a short time, while the temperature drop of the heat transfer section is slow As a major change, by allowing the second predetermined temperature to be reached over a longer period of time, the heat transfer section can be adapted to accommodate more features in the human body that receive cold stimulation than receptors that receive warm stimulation. In a warmed state, the degree of temperature rise is increased, and the receptor is activated by promptly reaching a high temperature range, so that a warm stimulus that has few receptors and is not easily transmitted to the skin can be reliably applied to the skin. In the state where the heat transfer unit is cooled, the degree of temperature decrease is relatively reduced to cool the heat transfer unit within a range where the cold stimulus that is easier to detect by the receptor than the temperature stimulus can be received by the skin. Can reduce the burden on the heat source. In particular, when the heat source is a Peltier element, the degree of generation of exhaust heat caused by heat absorption related to cooling of the heat transfer section can be reduced by gradual temperature change even during cooling when the load is generally higher than during heating. It is possible to reduce the heat radiation load of the exhaust heat by reducing the temperature, and the heat absorption can be performed without difficulty, and the temperature can be reliably lowered by appropriately cooling the heat transfer section.

  In addition, the beauty device according to the present invention provides the heat source unit to the heat source unit for a predetermined time after the state where the control unit heats the heat transfer unit and before the heat transfer unit is cooled as necessary. Control for stopping energization is executed.

  As described above, according to the present invention, a period for stopping energization of the heat source unit is provided between the state in which the heat source unit warms the heat transfer unit and the state in which the heat transfer unit is cooled. Give the heat transfer section that has reached the predetermined temperature a state in which the heat source section does not perform heating or cooling, and during this energization stop period, the heat transfer section gradually lowers the temperature little by little by natural heat dissipation. Thus, the state where the heat transfer unit is higher than the ambient environment temperature and is felt to be warm is maintained for a certain period without heating by energizing the heat source unit, and the heat transfer unit is moved from the first predetermined temperature. A state in which the temperature is gradually decreased can be realized without cooling by energization of the heat source unit, and power consumption for energization stop can be suppressed. Moreover, the temperature change of the heat transfer part when the heat transfer part is shifted from the warmed state to the cooled state can be set to a gradual transition state by sandwiching the slow cooling period accompanying the stop of energization. Reduces skin irritation caused by changes. Furthermore, in the heat source part, by sandwiching the energization stop period between the heat transfer part heating state and the cooling state, a rapid temperature change can be avoided, and the thermal load at the start of cooling can be suppressed and the power consumption can be suppressed. The mechanical stress of the heat source part and the heat transfer part based on the temperature change can be alleviated, and the durability of the heat source part and the heat transfer part can be improved.

  Further, in the beauty device disclosed by the present invention, if necessary, the heat source part is a Peltier element having front and back surfaces serving as a heat generation surface and a heat absorption surface, and the front surface or the back surface facing the heat transfer unit and the heat transfer unit It is arranged in the main body so that it can conduct heat to the back or front surface that does not face the heat transfer part of the heat source part, and the heat transmitted from the heat source part is released into the surrounding atmosphere. And a fan disposed in the main body so as to generate an air flow of air taken from the outside of the main body and apply the air flow to the heat radiator so that the radiator can be forcibly cooled. And the control unit operates the fan in a state where the heat transfer unit is cooled, and after the state where the heat transfer unit is cooled and before the next state where the heat transfer unit is cooled, Operates the fan during all or part of the period when the parts are not cooled And it executes the control to.

  Thus, according to the disclosure of the present invention, the heat source part is a Peltier element, and a heat radiator is provided on the side of the heat source part that does not face the heat transfer part, and the side that faces the heat transfer part of the heat source part is energized by energization. When the heat transfer part is cooled as a surface, the heat generated on the opposite heat generation surface can be released to the outside using a radiator and a fan, preventing overheating on the heat generation side and simultaneously generating heat at the heat source part The heat absorption progresses without delay so that the cooling of the heat transfer section can be continued and the fan is operated during the period when the heat source section does not cool the heat transfer section. If the heatsink is forced to cool, the heatsink that has received heat generated on the heat generation surface of the heat source while the heatsink is cooled, and the temperature is raised, the heatsink is still a fan after the heatsink is cooled. The degree to which the temperature is lowered by forced cooling is increased, and the next heat transfer section is cooled. The temperature of the heatsink can be greatly reduced when shifting to the state, and the heat source part is sufficiently secured to receive heat from the heat source part of the heatsink while the next heat transfer part is cooled. The amount of heat transferred to the heat generating side due to the endotherm in the heat source can be increased, that is, the ability of the heat source part to take heat from the heat transfer part and cool it can be increased. In addition to being able to avoid the situation where the cooling capacity decline due to insufficient heat capacity of the radiator when the heat transfer part is cooled and the situation where cooling cannot be performed can be avoided, the alternate application of alternating thermal and cold stimulation to the skin can be performed reliably. The temperature of the heat transfer section in the state where the heat transfer section is cooled after the first time is appropriately lowered to obtain a state in which the skin is comfortably cooled by the heat transfer section, so that the user does not have to feel insufficient about cooling the skin. .

  In the cosmetic device 1 according to the present embodiment, the head unit 12, the roller units 16, 17 and the irradiation unit 18 each apply predetermined stimuli related to beauty in a state where the head unit 12 is in contact with or in contact with the user's skin. It is provided as a stimulus applying part that can be applied to the skin.

  The main body portion 11 has a head portion 12 disposed at one end, and a grip portion having a thickness suitable for a user to hold the entire apparatus by gripping it by hand during use. 11a is formed, and the longitudinal direction of the gripping portion 11a and the front direction of the head portion 12 are inclined by a predetermined angle, and the inside of the control portion 19 and the like as an electric circuit and a power source A battery (not shown) is arranged.

On the front side of the gripping part 11a closer to the front side of the head part 12 in the main body part 11, an operation part for switching ON / OFF of the operation related to cosmetics, the type of operation, strength, etc. in response to the user's input operation 11b is disposed. An auxiliary electrode portion 14 made of a conductive member and connected to the control portion 19 is disposed on the back side of the grip portion 11a. When the user grips the grip portion 11a with his / her hand, the auxiliary electrode portion 14 Will come into contact.
Furthermore, a ring-shaped holding portion 12 b that holds a porous covering 12 a such as a cotton puff is attachable to and detachable from the head portion 12 around the head portion 12 in the main body portion 11.

  The operation unit 11b includes a power source / mode changeover switch 11c that enables selection of each operation execution and power OFF state in three types of operation modes related to beauty, and a temperature change in the head unit 12 that is a heat transfer unit. The temperature change setting switch 11d that can switch the state of the current and the strength changeover switch 11e that switches the strength of the energization current in the energization state of the skin according to each operation mode are provided.

  The head portion 12 is made of a material having conductivity and good thermal conductivity, such as metal, and has a convex shape, specifically, three corner portions having a large curvature, such as a bulging triangle, and an intermediate curvature therebetween. It has a trapezoidal shape having a contoured top surface composed of a small curved portion, and is arranged so as to protrude from the front surface side of one end portion of the main body 11 with the top surface side as a tip.

A heat source 13 is in contact with the head portion 12 from the inside of the main body portion 11 via an insulating material. The heat source portion 13 heats the head portion 12 as necessary by the heat source portion 13 so that the ambient temperature and body temperature are higher than a predetermined value. In this configuration, the temperature is raised to a temperature, or the temperature is lowered to a predetermined temperature that is lower than the ambient environment temperature by being cooled. And the head part 12 will give the user's skin the warm stimulus and the cold stimulus based on the temperature changed by such heating and cooling in the state which touches the user's skin.
The head unit 12 is electrically connected to the control unit 19 in the main body unit 11, and can be energized through the user's body with the auxiliary electrode unit 14 in the grip unit 11a.

  When energizing the skin 70 using the head unit 12, the user holds the gripping part 11 a to bring the user's palm or hand fingers into contact with the auxiliary electrode unit 14, and the control unit 19 controls the head. A porous material in which a voltage is applied between the portion 12 and the auxiliary electrode portion 14 so that energization can occur and the user impregnates the head portion 12 directly or with a liquid agent such as lotion containing an electrolyte component. It is made to contact skin 70, such as a face, via the covering 12a. Thereby, the head part 12 and the auxiliary electrode part 14 can be made into an electrical connection state via a user's body, and electricity supply to the skin 70 which the head part 12 contacts occurs.

  With the energization of the skin 70 in contact with the head 12, an ionic active ingredient contained in a liquid such as lotion that has been applied to the skin surface in advance or has been soaked in the porous coating 12 a, Ion introduction (iontophoresis) introduced into the skin by ion movement based on current from the control unit 19 can be executed. Further, as cleansing (ion derivation) of the skin 70, a state in which dirt components such as charged wastes are transferred from the skin side to the head portion 12 side by energization and taken into the porous covering 12a held on the head surface. It can also be obtained. Such ion introduction and cleansing techniques are known per se and will not be described in detail.

The heat source unit 13 is disposed in the vicinity of the head unit 12 inside the main body unit 11 and heats and cools the head unit 12 by changing the temperature by energization.
Specifically, the heat source unit 13 is a known Peltier element having a thin plate shape, and is disposed in a rear portion of the head unit 12 inside the main body unit 11, and a thin insulating material is provided between the head unit 12. By interposing it, the heat source unit 13 and the head unit 12 can be insulated from each other while maintaining good insulation between the heat source unit 13 and the head unit 12.

  This heat source unit 13 is electrically connected to the control unit 19 inside the main body unit 11 through a conducting wire, energized based on the control by the control unit 19, and heated to a preset temperature with the head unit side as a heat generating surface. And a state in which the temperature is lowered to a preset temperature with the head portion side as the endothermic surface. The mechanism of the temperature change of the heat source unit 13 is based on the well-known Peltier effect and will not be described in detail.

  The heat source unit 13 is energized as necessary under the control of the control unit 19 to change the head unit side to a temperature set in advance by the control unit 19, thereby generating heat conduction with the head unit 12. Thus, the head unit 12 is heated or cooled. And the liquid agent which was made to infiltrate the skin 70 and the porous coating body which the head part 12 contacts by the heat conduction through the head part 12 can be warmed or cooled.

  By controlling the energization state of the heat source unit 13 with the control unit 19, not only heating or cooling of the head unit 12 is performed within a time specified as one operation mode, but heating and cooling are sequentially switched. It is feasible.

  When the Peltier element forming the heat source unit 13 is energized so that the side facing the head unit 12 becomes an endothermic surface and cools the head unit 12, it does not properly dissipate heat on the heat generating surface where the temperature rises on the opposite side. Since the heat absorption at the same time is delayed, a mechanism for heat dissipation is also provided.

  Specifically, the heat source 13 is disposed in the main body 11 so as to be able to conduct heat with respect to the surface of the heat source 13 that does not face the head 12, so that heat transmitted from the heat source 13 can be released into the ambient atmosphere. A fan 13b disposed in the main body 11 so as to generate an air flow of the air taken from outside the main body 11 and the heat sink 13a and apply the air flow to the heat radiator 13a so that the heat radiator 13a can be forcibly cooled. It is the structure provided with. The fan 13 b is electrically connected to the control unit 19 and operates based on control by the control unit 19.

  The tilting arm portion 15 is a substantially arm-like member that is attached to one end portion of the main body portion 11 with the head portion 12 so as to be tiltable, and the roller portions 16 and 17 and the irradiation portion 18 are disposed at end portions away from the center of tilting. It is the structure which can be attached.

  The roller parts 16 and 17 are cylindrical bodies made of two conductors, and are arranged at predetermined intervals on the tip side away from the tilting center part of the tilting arm part 15 so as to be rotatable around axes parallel to each other. It is a configuration to be provided. Each roller part 16 and 17 is electrically connected to the control part 19 inside the main body part 11 through a conducting wire provided in the tilting arm part 15 and forms a pair of electrodes having different polarities.

  These roller parts 16 and 17 are exposed so as to be able to come into contact with the skin 70, and in a state where they are in contact with the skin 70, the controller 19 puts the roller parts 16 and 17 into an energized state via the skin 70. . Each of the roller portions 16 and 17 may be formed of a conductor such as metal, or may have a structure in which a conductor such as metal is attached to a surface of an elastic body such as rubber or a thin film of conductor is disposed.

  The irradiation unit 18 is fixed in the region between the two roller units 16 and 17 on the distal end side of the tilting arm unit 15 so as to be deeper than the roller units 16 and 17, and the two roller units 16 and 17 are fixed to the skin 70. In this configuration, the irradiation unit 18 faces the skin 70 and can irradiate the skin with light.

  The irradiation unit 18 irradiates visible light in a red region (wavelength of about 620 to 750 nm) and a yellow region (wavelength of about 570 to 590 nm) and near infrared region (wavelength of about 800) under irradiation control by the control unit 19. ˜1000 nm).

  The irradiation unit 18 employs a known structure in which a known light-emitting diode (LED) serving as a light source is covered with a light-transmitting cover, and detailed description thereof is omitted. The irradiation unit 18 is fixed to the tilting arm unit 15, and is electrically connected to the control unit 19 inside the main body unit 11 through a conducting wire provided in the tilting arm unit 15.

  The light from the irradiating unit 18 appears to be continuous light with a predetermined irradiation intensity at a predetermined irradiation intensity, that is, without flickering or the like, or intermittently, that is, Irradiation is performed such that the irradiation period and the non-irradiation period are alternately repeated.

  When energizing the roller parts 16 and 17 and irradiating light from the irradiation part 18, the tilting arm part 15 is tilted so that the irradiation part 18 and the roller parts 16 and 17 are positioned in front of the head part 12. 17 is brought into contact with the skin 70 (see FIGS. 4, 5, and 6). On the other hand, when energization and light irradiation by the roller portions 16 and 17 are not performed, such as ion introduction, the tilting arm portion 15 is tilted so that the roller portions 16 and 17 and the irradiation portion 18 are shifted from the front of the head portion 12, and the head portion. When 12 is in an open state, the head portion 12 can be covered with a porous covering or brought into contact with the skin 70 (see FIGS. 1, 2, and 3).

  The control unit 19 is built in the main body unit 11, receives an input operation to the operation unit 11 b of the user, controls energization to the heat source unit 13, and adjusts the heating / cooling state of the head unit 12 by the heat source unit 13. In addition to enabling, the energization between the head unit 12 and the auxiliary electrode unit 14, the energization between the paired roller units 16 and 17, and the light irradiation in the irradiation unit 18 are controlled.

  The control unit 19 sets the operation mode of each unit for each cosmetic application. In the present embodiment, the cleansing mode for removing harmful components and waste accumulated in the skin, and lotions such as lotion in the deep part of the skin. There are three modes: an ion introduction mode in which an ionic active ingredient is infiltrated to enhance moist feeling, and a roller energization and light irradiation mode that activates the skin to fix and penetrate the emulsion or cream.

  Among the operation modes, in the cleansing mode and the iontophoresis mode, the control unit 19 energizes between the head unit 12 and the auxiliary electrode unit 14. In the roller energization and light irradiation mode, the pair of roller parts 16 and 17 are energized, and the irradiation unit 18 is operated to emit light.

  Further, the control unit 19 sets three types of temperature change states in the head unit for applying thermal stimulation to the skin from the head unit 12 simultaneously or independently with the iontophoresis mode. Specifically, a heating / cooling alternate application mode in which a state in which the head unit 12 is warmed and a state in which the head unit 12 is cooled are alternately generated so that a thermal stimulus and a cold stimulus are alternately applied from the head unit 12 to the skin. And a warm stimulus application mode in which only the thermal stimulus is continuously applied to the skin while maintaining the head unit 12 in a warmed state, and only the cold stimulus is continuously applied to the skin while maintaining the head unit 12 in a cooled state. Each of the cold stimulus application modes to be set to be in a selectable state is set to be selectable.

  When the temperature change of the head unit 12 is caused in these three modes, the control unit 19 controls the energization state of the heat source unit 13 according to each mode to execute heating and cooling of the head unit 12. It becomes.

  For example, in the heating / cooling alternate application mode in which the state of heating the head unit 12 and the state of cooling the head unit 12 occur alternately, the control unit 19 appropriately heats and cools the head unit 12 by the heat source unit 13 at a predetermined timing. So that the warm period of the head section 12 (period in which the head section 12 is higher than the ambient environment temperature) and the cold period (period in which the head section 12 is lower than the ambient environment temperature) have the same length. In addition, the energization to the heat source unit 13 is controlled, and the heating and cooling of the head unit 12 by the heat source unit 13 are executed alternately. Thereby, the user can feel equally the amount of warm stimulation given to the skin from the head part 12 and the amount of cold stimulation.

  In addition, the control unit 19 operates the fan 13b in a state in which the head unit 12 is cooled by the heat source unit 13 so that the cooling of the head unit 12 by the heat source unit 13 can be performed without delay. In addition, after the state in which the head unit 12 is cooled and before the next state in which the head unit 12 is cooled, during a period in which the heat source unit 13 is not cooling the head unit 12, such as in the state in which the head unit 12 is warmed. In addition, the control unit 19 operates the fan 13b to cool the heat radiating unit 13a.

  As a specific example of the control related to the temperature change of the head unit 12, the control unit 19 is configured such that when the alternating heating / cooling mode is selected as the temperature change state of the head unit 12 when ion introduction is not performed, the heat source unit The head portion 12 is heated so that the surface of the head portion 13 is on the heat generation side, and the head portion 12 is heated. The temperature of the head portion 12 is set in the first period, for example, about 30 seconds from the start of the heating. The energization of the heat source unit 13 is controlled so as to shift to the first predetermined temperature, for example, 40 ° C. After the first period, the control unit 19 stops energization of the heat source unit 13 for a second period, for example, about 15 seconds, and the heat source unit 13 and the head unit 12 are brought into a natural heat dissipation state. The temperature is gradually decreased near the first predetermined temperature for a while.

  Subsequently, the control unit 19 energizes the head unit side surface of the heat source unit 13 to be on the heat absorption side to cool the head unit 12, and for a third period from the start of this cooling, for example, about The energization of the heat source unit 13 is controlled so that the temperature of the head unit 12 is lowered to a second predetermined temperature, for example, about 10 ° C. lower than the ambient environment temperature in 75 seconds. At the same time, the control unit 19 operates the fan 13b to appropriately release the heat generated on the heat generation side of the heat source unit 13 to the outside through the radiator 13a, and the cooling of the head unit 12 accompanying the heat absorption by the heat source unit 13 is continued. Make it executable.

  Thereafter, the control unit 19 switches the energization state to the heat source unit 13 to stop the cooling of the head unit 12 by the heat source unit 13 and again causes the surface of the heat source unit 13 on the head unit side to become the heat generation side. The series of control states are repeatedly executed by energizing and heating the head unit 12. However, when the head unit 12 is heated for the second and subsequent times by the heat source unit 13, the control unit 19 causes the operation of the fan 13b to reduce the temperature of the heat radiating unit 13a as much as possible and cool the next head unit 12. It will prepare for the state.

  The degree of temperature rise and temperature drop and the temperature change period of the head part 12 are made different from each other, and a period during which the head part 12 is not actively heated and cooled by stopping energization of the heat source part 13 is provided. By the energization control to be performed, the head unit 12 obtains a temperature change state in which the temperature period higher than the ambient environment temperature and the cool period lower than the ambient environment temperature are similarly about 1 minute in length (see FIG. 12). ) The user can feel equally the amount of warm and cold stimuli given to the skin.

  Further, in obtaining a temperature change state in which the warm period and the cold period in the head part 12 have the same length, by providing a period during which the control part 19 stops energization of the heat source part 13, Even if the time required for the head to reach each predetermined temperature is likely to vary due to minute differences in heating and cooling capabilities associated with individual differences, the deviation can be absorbed by adjusting the energization stop period. The period and cold period can be set to the same length without difficulty. In addition, since the period for stopping energization of the heat source unit 13 is provided, the period for cooling the head unit 12 by energizing the heat source unit 13 to reduce the temperature can be shortened. Power consumption can be suppressed by suppressing the operation related to cooling, especially when the power supply unit is a battery, suppressing the power input for the cooling operation of the heat source unit, and maintaining the power supply capacity of the battery to the maximum, The apparatus operating time when using the apparatus can be made longer.

  Further, the control unit 19 operates the fan 13b to forcibly cool the radiator 13a during a period when the heat source unit 13 does not cool the head unit 12, thereby cooling the head unit 12 to the heat generating surface of the heat source unit 13. The radiator 13a, which has received the generated heat and raised its temperature, is forcibly cooled by the fan 13b even after the head portion 12 is cooled, and the degree of lowering the temperature is increased to cool the next head portion 12. When shifting to the state, a state in which the temperature of the radiator 13a is greatly reduced is obtained. This ensures a sufficient heat capacity that can receive heat from the heat source 13 of the radiator 13a while the next head 12 is cooled, and increases the amount of heat that can be moved to the heat generation side by heat absorption in the heat source 13. That is, the ability of the heat source unit 13 to take heat from the head unit 12 and cool it can be increased. In this way, it is possible to avoid a situation where the cooling capacity is lowered due to insufficient heat capacity of the radiator 13a after the head portion 12 is cooled and the cooling cannot be performed after the head portion 12 is cooled. The alternate application of the stimulus and the cold stimulus can be surely continued.

  Switching of the operation mode in the control unit 19 is performed based on a user input operation to the power source / mode switch 11c of the operation unit 11b. Further, switching of the three modes of the temperature change state in the head unit 12 is performed based on a user input operation to the temperature change setting switch 11d of the operation unit 11b.

  When the beauty device 10 is used, when the user first operates the power supply / mode changeover switch 11c from the OFF state where the beauty device 10 is not operated, the control unit 19 performs the cleansing mode, the ion introduction mode, the roller energization, and the light irradiation. Each of the modes can be executed, and each time the switch is pressed, the operation of each mode and the four states of power OFF are sequentially switched.

  In addition, when the temperature change setting switch 11d is first operated from the OFF state in which the beauty device 10 is not operated, the control unit 19 executes any one of the alternate heating / cooling mode, the warm stimulus applying mode, and the cool stimulus applying mode. It becomes possible. Also in this case, every time the temperature change setting switch 11d is pressed, the control unit 19 sequentially switches between the four states of operation of each mode and power OFF.

  In addition, when the temperature change setting switch 11d is operated in a state where the power supply / mode changeover switch 11c is operated and the ion introduction mode is selected as the operation mode, the control unit 19 energizes the ion introduction selected as the operation mode. In parallel with the execution, the energization control of the heat source unit 13 according to the mode selected by operating the temperature change setting switch 11d is executed, and a predetermined temperature change state is given to the head unit 12 in the selected mode. It becomes. In this case, the control unit 19 operates each mode related to the temperature change state of the head unit 12 and energizes the heat source unit 13 every time the temperature change setting switch 11d is operated in parallel with the control related to ion introduction. The four states of OFF (only ion introduction) are sequentially switched.

  On the other hand, when the cleansing mode, the roller energization and the light irradiation mode are selected as the operation mode, the subsequent operation of the temperature change setting switch 11d is invalidated, and the operation of each mode and the energization to the heat source unit 13 are performed simultaneously. There is no execution.

  In addition, when the control unit 19 energizes between the head unit 12 and the auxiliary electrode unit 14 or between the roller units 16 and 17 corresponding to each operation mode, the current flowing through the user's skin due to this energization is determined. Strength adjustment control will be performed. This adjustment is performed based on a user's input operation to the strength changeover switch 11e provided in the operation portion 11b. Each time the strength changeover switch 11e is pressed, the control portion 19 sets the strength of the four levels of energization. Switch sequentially.

  As described above, the operation mode related to energization can be selected and switched by the power source / mode switch 11c of the operation unit 11b, and the mode related to the temperature change state in the head unit 12 can be selected and switched by the temperature change setting switch 11d. Therefore, the temperature change mode can be selected independently of the operation mode, the operation related to energization and the operation related to the head temperature are separated, and the user can perform the operation intuitively. Excellent. In addition, the setting of the temperature change state in the head portion 12 at the time of ion introduction can also be performed by operating the temperature change setting switch 11d after selection of ion introduction, and can be set flexibly according to the situation at that time, the state of the skin, For example, the temperature can be selected in accordance with the skin condition after the start of ion introduction, and the device operating state more suitable for the user can be obtained, and the comfort and satisfaction after applying the stimulus can be improved. In addition, in the case where only the thermal and thermal stimulation is applied from the head unit 12 to the skin, only the temperature change setting switch 11d needs to be operated, and the operation can be extremely facilitated.

  Next, the operating state of the beauty device according to the present embodiment will be described. As a premise, it is assumed that the user holds the grip portion 11a of the beauty apparatus 1 and directs the head portion 12 or the roller portions 16 and 17 toward the skin site to be used. The power supply unit (battery) of the beauty device 1 has a sufficient capacity, and if the mode is selected and input with each switch of the operation unit 11b, the operation of each mode is performed without difficulty until the end of a preset period. It is assumed that it can continue.

  When performing cleansing or ion introduction using the head unit 12, the user tilts the tilting arm unit 15 in advance to shift the roller units 16, 17 and the irradiation unit 18 from the front of the head unit 12, and the head unit 12 is moved to the skin 70. (See FIGS. 1, 2, and 3). In the case of cleansing, a skin lotion for wiping containing an electrolyte component, or in the case of ion introduction, a protective lotion containing an electrolyte component is directly applied to the skin, or a porous covering 12a such as a cotton puff. So that the porous coating is held on the head portion 12.

  When the user selects the cleansing mode (1C) or the iontophoresis mode (2C) by operating the power supply / mode changeover switch 11c of the operation unit 11b, specifically, an operation of pressing once from the power OFF state is performed. When the cleansing mode is selected or the ion introduction mode is selected by pressing twice from the power OFF state, the control unit 19 makes a weak pulse-like weak cycle between the head unit 12 and the auxiliary electrode unit 14. It enables the start of an energized state in which current flows. However, in a state in which the head portion 12 is separated from the skin 70, since the circuit between the head portion 12 and the auxiliary electrode portion 14 is not closed via the body, there is no energization.

  When the user moves the beauty device 10 to be held, and the head unit 12 is brought into contact with the skin 70 directly or through the porous coating 12a, the head unit 12 and the auxiliary electrode unit 14 are separated from the user's body. Then, it is energized through a lotion that has been applied to the skin surface in advance or has been impregnated into the porous coating. In the case of cleansing, the dirt on the skin can be removed by transferring the charged fine dirt components on the skin surface and inside from the skin side to the porous coating body side (see FIG. 8). In addition, in the case of ion introduction, the ionic active ingredient in the skin lotion can be transferred to the skin side to penetrate the active ingredient into the skin (see FIG. 9).

  When the user moves the head portion 12 on the skin little by little while keeping the head portion 12 in contact with the skin 70, the target position for cleansing and ion introduction can be changed while the energized state is maintained. However, when the head portion 12 is separated from the skin 70, energization is immediately interrupted. When cleansing or ion introduction is completed, the user may switch to another operation mode or the power OFF state by operating the power / mode switch 11c of the operation unit 11b. In addition, the controller 19 may stop energization after a preset time for cleansing or ion introduction. After the end of these modes, the user preferably removes the porous coating from the head unit 12 when it is used, and then cleans the surface of the head unit 12 to prepare for the next use. .

  On the other hand, when the ion introduction is performed while causing a predetermined temperature change in the head unit 12, in addition to the ion introduction being selected by the user's operation of the power source / mode change-over switch 11c as described above, A temperature change mode is selected by the user's operation of the temperature change setting switch 11d.

  In response to the user's operation, the control unit 19 makes it possible to start energization to pass a weak pulsed current between the head unit 12 and the auxiliary electrode unit 14 in a short cycle. Further, the control unit 19 energizes the heat source unit 13 to start the temperature change of the head unit 12.

  When the user operates the temperature change setting switch 11d, specifically by pressing once from the power-off state and selects the alternate heating / cooling mode, the control unit 19 first sets the heat source unit 13 to the head unit. The head 12 is controlled to be heated to a first predetermined temperature (for example, about 44 ° C.) higher than the ambient temperature. Further, even when the user operates the temperature change setting switch 11d, specifically, by pressing twice from the power-off state and selects the warm stimulus application mode, the control unit 19 uses the heat source unit 13 as the head. The head portion 12 is moved to a first predetermined temperature (for example, about 44 ° C.) higher than the ambient environment temperature by heating the portion 12. On the other hand, when the user selects the cold stimulus application mode by operating the temperature change setting switch 11d, specifically by pressing three times from the power OFF state, the control unit 19 first uses the heat source unit 13 to The head unit 12 is controlled to cool down, and the head unit 12 is shifted to a second predetermined temperature lower than the ambient environment temperature (for example, a temperature about 10 ° C. lower than the ambient environment temperature).

  As described above, the head unit 12 is not energized while being separated from the skin 70. However, when the user moves the beauty device 10 and brings the head unit 12 into contact with the skin 70 directly or via the porous coating. The head portion 12 and the auxiliary electrode portion 14 are energized through the user's body and the skin lotion that has been applied to the skin surface in advance or soaked into the porous coating. Thereby, the ionic active ingredient in the lotion can be transferred to the skin side, and the active ingredient can be penetrated into the skin.

  In addition, the head portion 12 that comes into contact with the skin 70 directly or through the porous covering body is in a state in which the temperature is changed to a temperature different from the ambient environment temperature by heating or cooling of the heat source portion 13. Yes. Thereby, when the head part 12 is heated, the porous covering 12a and the skin 70 are warmed by the head part 12 which is set to an appropriate temperature (first predetermined temperature) higher than the ambient environment temperature. As a result, the activity of the skin lotion in the porous covering 12a is increased, and the skin 70 is also changed to a state where the active ingredient can easily penetrate, and the transfer of the ionic active ingredient into the skin is further promoted. In addition, non-electrolyte water-soluble active ingredients and oil-soluble active ingredients in the lotion easily penetrate into the skin 70, and these various active ingredients penetrate deep into the skin 70 to surely give a cosmetic effect. .

  On the other hand, when the head portion 12 is cooled to lower the temperature, the skin 70 is deprived of heat by the head portion 12 having an appropriate temperature (second predetermined temperature) lower than the ambient environment temperature. As a result, the temperature is lowered and the temperature is lowered, and the coldness is felt. If ion introduction is performed in the summer when the ambient temperature is high or when the temperature of the skin is high, the ion introduction is performed in a comfortable state by lowering the temperature of the head 12 in this way. It is possible to give a relaxed feeling with a beauty effect. In addition, some people may experience discomfort such as pain and itchiness and inflammation of the skin surface due to the energization of the skin due to the introduction of ions, but the sedative effect of cooling the skin may cause such discomfort and inflammation. Can be relaxed.

  In addition, when the user has selected the alternate heating / cooling mode by operating the temperature change setting switch 11d, the heat source unit 13 is obtained when a predetermined time, for example, 2 minutes elapses after the head unit 12 starts to be heated by the heat source unit. Is switched from a state in which the head unit 12 is heated to a state in which the head unit 12 is cooled, the head unit 12 is cooled and the temperature is lowered, and the head unit 12 is cooled to a second predetermined temperature (for example, the ambient environment). The temperature is about 10 ° C. lower than the temperature). In the first half of the ion introduction in which the head unit 12 is warmed by the head unit 12 in which the heated state and the cooled state are alternately generated by being heated by the heat source unit 13 and then cooled, In the latter half of the ion introduction, the ion introduction is continued while cooling the skin 70 with the head portion 12 whose temperature has been lowered, and in the summer or after taking a bath. In this situation, ion introduction can be carried out comfortably, and both penetration of active ingredients and comfort can be improved without difficulty. Furthermore, the skin 70 in contact with the head portion 12 is cooled and the temperature is lowered, whereby the skin 70 is tightened, and the active ingredients once permeated into the skin are fixed without escaping to the outside, and their effects can be enhanced.

  During such ion introduction, if the user moves the head portion 12 on the skin little by little while keeping the head portion 12 in contact with the skin 70, the target position of the ion introduction can be changed while being energized, and warmed by the head portion 12 together. The position of the skin that is to be cooled or cooled will also change. However, when the head portion 12 is separated from the skin 70, the energization for ion introduction is immediately interrupted.

  When the ion introduction with such a temperature change of the head unit 12 is completed, the user can switch to another operation mode or the power OFF state by operating the power / mode switch 11c of the operation unit 11b. That's fine. In addition, after a preset time for ion introduction, the control unit 19 stops energization between the head unit 12 and the auxiliary electrode unit 14, and also stops energization to the heat source unit 13, thereby introducing the ion introduction and head unit. The temperature change of 12 is finished. After the completion, it is desirable that the user removes the porous covering from the head part 12 and cleans the surface of the head part 12 to prepare for the next use.

  When the roller energization and light irradiation are performed, the user tilts the tilting arm portion 15 so that the roller portions 16 and 17 and the irradiation portion 18 are located on the front side of the head portion 12, and the roller portions 16 and 17 are the skin 70. (See FIGS. 4, 5, and 6). At the same time, apply a milky lotion or cream to the skin and let it become familiar.

  When the user operates the power / mode changeover switch 11c of the operation unit 11b, specifically, presses the power supply OFF state three times to select the roller energization and light irradiation mode (3C), the control unit 19 Enables the start of an energized state in which a pulse-like weak current is passed between the paired roller portions 16 and 17 in a short cycle, and light irradiation in the irradiation portion 18 is also started. However, in a state where the roller parts 16 and 17 are separated from the skin 70, since the circuit between the roller parts 16 and 17 is not closed via the skin (skin), there is no energization. In this roller energization and light irradiation mode, the operation of the temperature change setting switch 11d is invalid, and even if the operation is performed, the head portion 12 is not heated or cooled by the heat source unit 13.

  When the roller parts 16 and 17 are brought into close contact with the skin 70 (see FIG. 10), the energized state is passed through the skin between the paired roller parts 16 and 17, the skin is stimulated by energization, the skin is activated, and the emulsion And will promote the penetration of cream. Further, the skin receives light with an appropriate irradiation intensity from the irradiation unit 18, and a cosmetic effect by the light is also produced.

  When the roller parts 16 and 17 are rolled while being kept in contact with the skin 70 and moved gradually on the skin, the energization and light irradiation target positions can be changed, but the energization is interrupted or the energization and irradiation positions are changed. Therefore, when the roller parts 16 and 17 are separated from the skin 70, the energization between the roller parts is immediately interrupted. When the energization and irradiation are completely finished, the user can switch between another operation mode or the power-off state with the power / mode changeover switch 11c of the operation unit 11b. Irradiation of light is stopped.

  In addition, in the case where only the thermal stimulation is applied to the skin from the head unit 12 whose temperature has been changed, the user tilts the tilting arm unit 15 in advance, and the roller units 16 and 17 and the irradiation unit 18. Is shifted from the front of the head unit 12 so that the head unit 12 is in an open state in which the head unit 12 can come into contact with the skin 70 (see FIGS. 1, 2, and 3). If necessary, the skin 70 is kept in a state of being applied with an emulsion or cream.

  When the state of temperature change in the head unit 12 is selected from three modes by operating the temperature change setting switch 11d from the power-off state of the user, the control unit 19 energizes the heat source unit 13 to perform the head unit 12 Heating or cooling is started, and the temperature of the head portion is changed. In this case, energization between the head unit 12 and the auxiliary electrode unit 14 is not performed.

  When the user moves the held beauty device 10 to bring the head portion 12 into contact with the skin 70, heat conduction occurs between the head portion 12 and the skin (see FIG. 11). As a result, thermal stimulation according to the selected temperature change state is given to the skin.

  When the user operates the temperature change setting switch 11d, specifically, presses once from the power-off state and selects the alternate heating / cooling mode, the control unit 19 has the heat source unit 13 The head unit 12 is controlled to be heated so that the head unit 12 is shifted to a first predetermined temperature (for example, about 40 ° C.) higher than the ambient temperature, and the heat source unit 13 is controlled to cool the head unit 12. Then, the state in which the head unit 12 is shifted to a second predetermined temperature lower than the ambient environment temperature (for example, a temperature about 10 ° C. lower than the ambient environment temperature) is alternately repeated (see FIG. 12).

  Specifically, the control unit 19 first heats the head unit 12 by energizing the heat source unit 13 so that the surface on the head unit side becomes the heat generation side. The control unit 19 causes the temperature of the head unit 12 to reach a first predetermined temperature, for example, 40 ° C., within a first preset period, for example, about 30 seconds, from the start of the heating, This temperature is maintained after the first predetermined temperature is reached. And after progress of said 1st period, the control part 19 stops energization to the heat-source part 13 over a 2nd period, for example, 15 seconds, and heats (and cools) the head part 12 by the heat-source part 13 is performed. First, the heat source unit 13 and the head unit 12 are in a natural heat dissipation state. In the second period in which the energization is stopped, the temperature of the head unit 12 begins to gradually decrease from the first predetermined temperature.

  Subsequently, while the fan 13b is operated, the control unit 19 energizes the head unit side surface of the heat source unit 13 to the heat absorption side, thereby cooling the head unit 12. The control unit 19 cools the head unit 12 to the second predetermined temperature, specifically, the ambient environment by cooling by the heat source unit 13 within a preset third period, for example, 75 seconds, from the start of the cooling. The temperature is lowered to a temperature lower than the temperature by a predetermined temperature (for example, 10 ° C.), for example, 15 ° C. when the temperature of the room air as the ambient environment temperature is 25 ° C.

  After the elapse of the third period for cooling the head unit 12, the control unit 19 switches the energization state to the heat source unit 13 again to stop the cooling of the head unit 12 by the heat source unit 13, and again the heat source unit 13 The series of temperature control states are repeatedly performed again by energizing the head portion side surface to the heat generation side and heating the head portion 12 in the same manner as described above.

  However, for the second heating of the head unit 12 by the heat source unit 13, the temperature of the head unit 12 at the start of heating is the second predetermined temperature reached by the previous cooling, and the first head unit 12 is heated. Therefore, the control unit 19 changes the control parameter related to the temperature rise of the head unit 12 with respect to the heat source unit 13 and adjusts the degree of temperature rise of the head unit 12 to control the heating. The temperature of the head unit 12 is made to reach the first predetermined temperature during the first period, which is the same as the case of heating the head unit 12 for the first time from the start, and the temperature is higher than the ambient temperature of the head unit 12. The high temperature period is constant regardless of the number of heating times of the head unit 12, so that the user can feel the amount of warm stimulation given to the skin evenly. In addition, when the head unit 12 is heated by the heat source unit 13 for the second time, the control unit 19 operates the fan 13b, and the radiator 13a that has greatly increased the temperature while the previous head unit 12 is cooled. The temperature is greatly reduced by forced cooling by the fan 13b, and then the second head portion 12 is cooled. For this reason, even when the head part 12 is cooled for the second time, a sufficient heat capacity is received to receive heat from the heat source part 13 of the radiator 13a, and the amount of heat transferred from the head part 12 to the radiator 13a through the heat source part 13 Can be avoided, and it is possible to avoid a situation in which the cooling capacity is lowered or the cooling cannot be performed, such as when the heat radiator temperature is high and the heat capacity cannot be secured in the state where the head portion 12 is cooled. The application of warm and cold stimulation based on the mode can proceed without any problems.

  After the second cooling of the head unit 12 (4 minutes after the start of the first heating), the control unit 19 stops energization of the heat source unit 13 and stops the cooling of the head unit 12 by the heat source unit 13. Thereafter, when the heat source unit 13 and the head unit 12 naturally increase the temperature to the ambient environment temperature due to the influence of the surroundings, the temperature change of the head unit 12 according to the alternate heating / cooling mode ends.

  When the control unit 19 performs the control to alternately generate the state in which the head unit 12 is warmed to give the skin a warm stimulus and the state in which the head unit 12 is cooled to give the skin a cold stimulus, Since the state of the heat source unit 13 and other states differ between when the head unit 12 is heated and cooled and when the head unit 12 is heated and cooled for the second time, the control unit 19 performs the first head unit 12. The control content is changed between the control during heating and cooling of the head and the control during heating and cooling of the head portion 12 for the second time so that the repeated warm and cool periods have the same length regardless of the number of times. ing.

  Specifically, due to the characteristics of the heat source section 13 that is a Peltier element, the heat generation amount when the head section 12 is cooled is large, and the heat source section 13 is cooled by the heat source section 13 after the first cooling of the head section 12. Even if the fan 13b is forcibly cooled, the temperature of the radiator 13a at the time when the cooling of the second head portion 12 is started cannot be lowered to the temperature when the cooling of the first head portion 12 is started. For this reason, the heat transfer from the heat source 13 to the radiator 13a hardly occurs in the second cooling of the head unit 12 by the heat source unit 13 because the radiator temperature at the start of cooling is high, and the heat source unit 13 accompanies heat absorption. Since the heat generated in step S3 cannot be radiated smoothly, the degree of temperature drop of the head unit 12 becomes smaller than that in the first cooling of the head unit 12.

  Based on this, the control unit 19 performs the second heating and cooling of the head unit 12, the timing at which the heated head unit 12 reaches the peak of temperature change (maximum value), that is, the maximum temperature, and the cooled head unit. Control is performed so that the timing at which 12 reaches the peak (minimum value) of the temperature change, that is, the minimum temperature is advanced. On the other hand, in the heating and cooling of the head unit 12 for the first time, the control unit 19 determines when the heated head unit 12 reaches the peak (maximum value) of the temperature change, that is, the maximum temperature, Control is performed so that the peak (minimum value) of the temperature change, that is, the timing of reaching the minimum temperature is made slower than in the case of the second heating and cooling, respectively. Thus, the control unit 19 delays the first cold period of the head unit 12 based on the cooling of the head unit 12 by the first heating and cooling of the head unit 12 by the heat source unit 13, and makes the cooling period moderate. At the same time as the length, the length of the preceding warm period can be adjusted to make the warm period and the cold period the same length. In addition, in the second heating and cooling of the head unit 12 by the heat source unit 13, the control unit 19 performs cooling in a state in which the degree of temperature drop of the head unit 12 is smaller than the first time because the peak timing is advanced. However, it is possible to secure a sufficiently long cooling period of the second head section 12 that occurs from the latter half of the second cooling period to the natural temperature increase period after the cooling stop, and the second head section 12 before that. The temperature period can be suppressed to an appropriate length, and as a result, the first and second temperature periods and the cold period can be reliably adjusted to the same length (see FIG. 13).

  In this alternate heating / cooling mode, there are two types of heat conduction between the head portion 12 and the skin that are in contact with each other, one from the head portion 12 toward the skin 70 and the other from the skin toward the head portion 12. A warm stimulus due to heat transfer from the head portion 12 having a high temperature to the skin and a cold stimulus due to the heat of the skin being deprived by the head portion 12 having a low temperature are alternately generated, and each stimulus of this warm and cool is alternately applied. The state, that is, the state that causes a large temperature change that cannot occur in the normal situation in the skin is repeated, such as the effect of promoting blood circulation and metabolism in the skin by warm stimulation, the effect of tightening the skin by cold stimulation, Not only the effect on the skin for each stimulus, but also the effect of blood circulation promotion and fatigue recovery based on the alternate application of warm and cold to the muscles directly under the skin. Also, it can achieve a tension relief effect similar to that when performing massage on muscles, and can eliminate skin sagging, especially in the face, with a synergistic effect on skin and muscles. it can. In addition, such an effect can be obtained efficiently simply by applying the head portion 12 that changes in temperature to the skin, and it is excellent in terms of user convenience.

  In addition, the energization to the heat source unit 13 is controlled so that the temperature increase degree of the head unit 12 in the state in which the head unit 12 is warmed is larger than the temperature decrease degree in the head unit 12 in the state in which the head unit 12 is cooled. As for the temperature rise, the first predetermined temperature is reached in a short time as an abrupt change, while the temperature drop of the head part 12 is allowed to reach the second predetermined temperature over a longer time as a slow change. Accordingly, in response to the feature that the number of receptors that receive cold stimulation in the human body is larger than that of receptors that receive warm stimulation, in the state where the head portion 12 is warmed, the degree of temperature increase is increased and the temperature is rapidly reached. The receptor can be activated, and a warm stimulus that has few receptors and is not easily transmitted to the skin can be applied to the skin for as long as possible. In the state in which the head portion 12 is cooled, the degree of temperature decrease is relatively reduced within a range in which the cold stimulus that is easily detected by the receptor compared to the warm stimulus is sufficiently received by the skin, that is, when the head portion is heated. By reducing the temperature change during cooling of the head part, which increases the load, in the heat source part 13 which is a Peltier element, the degree of exhaust heat generated due to heat absorption related to the cooling of the head part 12 is reduced, thereby The heat radiation load can be reduced and the heat absorption can be performed without difficulty, and the head portion 12 can be appropriately cooled to reliably reduce its temperature.

  In addition, a period for stopping energization of the heat source unit 13 is provided between the state in which the heat source unit 13 warms the head unit 12 and the state in which the head unit 12 is cooled (see FIG. 12). By causing the head portion 12 to gradually decrease the temperature gradually due to natural heat dissipation, the state in which the head portion 12 is at a temperature that is higher than the ambient temperature and feels warm is accompanied by heating by energizing the heat source portion 13. Without being cooled by energization of the heat source unit 13 and maintaining the head unit 12 gradually decreasing the temperature from the first predetermined temperature without reducing the power consumption for energization stop. It can be suppressed. Further, the temperature change of the head unit 12 when the head unit 12 is shifted from the warmed state to the cooled state can be brought into a gradual transition state by sandwiching the slow cooling period accompanying the energization stop. Reduces skin irritation caused by changes. Furthermore, in the heat source unit 13 as well, it is possible to avoid a sudden temperature change by sandwiching the energization stop period between the heating state and the cooling state of the head portion 12, and to suppress power consumption by suppressing the thermal load at the start of cooling. In addition, the mechanical stress of the heat source unit 13 and the head unit 12 based on the temperature change can be alleviated, and the durability of the heat source unit 13 and the head unit 12 can be enhanced.

  In addition, when the user operates the temperature change setting switch 11d, specifically performs an operation of pressing twice from the power-off state and selects the warm stimulus application mode, the control unit 19 The heat source unit 13 is controlled to heat the head unit 12, and the head unit 12 is shifted to a predetermined temperature higher than the ambient environment temperature. Specifically, the control unit 19 energizes the head unit side surface of the heat source unit 13 to be the heat generation side, heats the head unit 12, and sets the temperature of the head unit 12 to a first predetermined value. The temperature is reached, for example, 40 ° C., and this temperature is maintained after the first predetermined temperature is reached.

  When the head part 12 whose temperature has been increased by the heat source part 13 is brought into close contact with the skin 70, the skin and cream are heated, and the user moves the main body part 11 while pressing the head part 12 against the skin 70. Warm up. At this time, if the skin 70 is massaged with the head 12 and the skin is warmed while massaging, the massage effect is enhanced. By warming the skin, it promotes blood circulation and metabolism of the skin, and the thermal stimulus applied to the skin changes the state so that the skin is easily absorbed. The active ingredient in it penetrates smoothly and the beauty effect is further enhanced.

  When the application of the temperature stimulus to the skin based on the temperature change of the head unit 12 is finished, the user moves the head unit 12 away from the skin 70 and operates the temperature change setting switch 11d of the operation unit 11b. What is necessary is just to switch to a power-OFF state. In addition, when a predetermined period, for example, about 3 minutes, elapses from the start of heating of the head unit 12 by the heat source unit 13, the control unit 19 stops energization of the heat source unit 13, and the head by the heat source unit 13 The heating of the part 12 is stopped, and the temperature change of the head part 12 according to the warm stimulus applying mode is completed. After completion, it is desirable for the user to clean the surface of the head unit 12 so that it is ready for the next use.

  After the energization of the heat source unit 13 is stopped, when the temperature of the head unit 12 is not changed based on another mode, the heat source unit 13 and the head unit 12 naturally reduce the temperature to the ambient environment temperature due to the influence of the surroundings. It becomes.

  Furthermore, when the user operates the temperature change setting switch 11d, specifically, performs an operation of pressing three times from the power-off state and selects the cold stimulus application mode, the control unit 19 The heat source unit 13 is controlled to cool the head unit 12, and the head unit 12 is shifted to a predetermined temperature lower than the ambient temperature. Specifically, the control unit 19 energizes the head unit side surface of the heat source unit 13 to be the heat absorption side, cools the head unit 12, and sets the temperature of the head unit 12 to a second predetermined temperature. The temperature is reduced to a predetermined temperature (for example, 10 ° C.) lower than the ambient temperature, for example, to 15 ° C. when the ambient air temperature is 25 ° C. Once this is reached, this temperature should be maintained.

  When the head part 12 whose temperature has been lowered by the heat source part 13 is brought into close contact with the skin 70, the skin is cooled, and the user moves the main body part 11 while pressing the head part 12 against the skin 70 to move the skin. cool. Even in a region near the portion of the skin 70 that contacts the head portion 12, for example, other than the portion where the head portion 12 directly contacts, the head portion 12 is indirectly affected by blood circulation or the like, and the temperature is lowered. In this way, the portion in contact with the head portion 12 having a low temperature and the surrounding skin 70 are cooled, whereby the skin 70 is tightened, and the active ingredient once permeated into the skin by ion introduction performed before this is released to the outside. The effect based on these components can be enhanced.

  In addition, in the summer when the ambient temperature is high, or in the situation where the temperature of the skin is high, when the head portion 12 with the lowered temperature is applied to the skin, the excessive heat of the skin is cooled and comfortable and calm. It is possible to obtain a relaxed state, and it is possible to give a sense of relaxation, and to appropriately perform other work related to beauty on the skin thereafter.

  When the application of the cold stimulus to the skin based on the temperature change of the head unit 12 is finished, the user moves the head unit 12 away from the skin 70 and operates the temperature change setting switch 11d of the operation unit 11b to switch to another mode or power off. What is necessary is just to switch to a state. In addition, when a predetermined period, for example, about 3 minutes, elapses from the start of cooling of the head unit 12 by the heat source unit 13, the control unit 19 stops energizing the heat source unit 13, and the head by the heat source unit 13 The cooling of the part 12 is stopped, and the temperature change of the head part 12 according to the cold stimulus applying mode is completed. After completion, it is desirable for the user to clean the surface of the head unit 12 so that it is ready for the next use.

  After the power supply to the heat source unit 13 is stopped, when the temperature of the head unit 12 is not changed based on another mode, the heat source unit 13 and the head unit 12 naturally increase the temperature to the ambient environment temperature due to the influence of the surroundings. It becomes.

  As described above, the beauty device according to the present embodiment is provided with the head unit 12 as a heat transfer unit that changes the temperature and applies a stimulus based on the temperature to the skin, and is based on energization control by the control unit 19. The heat source unit 13 for heating and cooling the head unit 12 is provided, and the control unit 19 controls the temperature of the heat source unit 13 with the head unit 12 approaching or contacting the user's skin. Since the head portion 12 is heated alternately and the head portion 12 is cooled alternately, the head portion 12 continuously applies warm and cold stimuli to the skin. The head portion 12 can be provided with a cold stimulus subsequent to the warm stimulus, and the discomfort that may occur when the preceding warm stimulus is applied to the skin can be alleviated and suppressed by the subsequent cold stimulus. Effects and irritation due to temperature changes, a synergistic effect being performed iontophoresis same time, the reasonably appropriate can be given to the skin. In addition, when alternately applying a warm stimulus and a cool stimulus to the skin by the head unit 12, for example, a switching operation by a user in each operation mode for executing a warm stimulus and a cool stimulus, The device operation for exchanging each stimulus applying portion for applying the stimulus and making it contact with the skin becomes unnecessary, the stimulus applying state can be easily obtained, and the user does not have to feel troublesome operation.

  Further, the control unit 19 controls the heating and cooling states of the head unit 12 by the heat source unit 13, and a time period in which the head unit temperature is higher than the ambient environment temperature and a cool period in which the head unit temperature is lower than the ambient environment temperature are time. Therefore, the balance between warm and cold stimuli balances the effect of one of the stimuli applied to the skin and the effect of the lesser stimuli on the skin. The user can feel the amount of warm and cold stimulation given to the skin from the head 12 evenly, and the user can feel the amount of warm and cold stimulation equally. Therefore, an appropriate stimulus application state can be obtained without causing an excessive or insufficient feeling. In particular, by giving the same level of warm and cold stimuli to the skin from the head unit 12, a large temperature change that cannot occur in normal conditions is caused to the skin, and a change in blood flow is promoted. The tension state of the muscles under the skin is also changed, so that the sagging of the skin, so-called lift-up, can be achieved.

  In the beauty device according to the embodiment, the outer shape of the roller portions 16 and 17 is formed as a simple cylindrical surface. However, the present invention is not limited to this, and a contact area between the roller portion and the skin is ensured. The roller part can be formed in a shape having irregularities on the surface within a range that can ensure the energization performance to the skin. When the roller part and the skin are brought into contact with each other, direct contact with the skin by the contact is possible. It is possible to give a kind of massage effect by encouraging further generation of various stimuli. For example, if the roller part is a rotationally symmetric body having an outer shape having a plurality of irregularities and rolled while applying the roller part to the skin, the skin is intermittently pressed, and the skin is repeatedly tapped with a finger. It can also be set as the structure which can provide irritation | stimulation like what is called a tapping massage.

  Further, in the beauty device according to the embodiment, the second predetermined temperature as the target temperature of the head unit 12 in a state where the head unit 12 is cooled by the heat source unit 13 is set to a predetermined temperature (for example, from the ambient environment temperature by the control unit 19). 10 ° C) is a configuration that is set to a low temperature, and this second predetermined temperature is handled as a fixed value that is set in advance as the temperature difference from the ambient environment temperature, regardless of the ambient temperature conditions. Although the control can be simplified and preferable in terms of cost, the present invention is not limited to this, and the temperature difference between the second predetermined temperature and the ambient environment temperature can be controlled to vary depending on the ambient environment temperature. For example, when the ambient temperature is low, such as in winter, if the head is cooled by simply setting the temperature difference from the ambient temperature of the second predetermined temperature to the initial setting, the head will cool excessively. In such a situation, the degree of temperature drop of the head part is suppressed, that is, the temperature difference between the second predetermined temperature and the ambient environment temperature is brought into contact with the skin. In such a case, adjustment control may be performed so as to reduce the size while maintaining a state in which the user feels cold. Thereby, the excessive temperature difference of a head part and skin is relieve | moderated, and the discomfort and discomfort at the time of skin touching a head part can be suppressed. Moreover, as a result of controlling to suppress the cooling of the head part by the heat source part, the power consumption of the power supply part related to the cooling can be suppressed by not performing the cooling more than necessary, and the apparatus usage time can be prolonged.
