You can take care of your skin. In addition, during the cooling preparation time, the sound generated by the rotation of the air blowing means 31 is reduced when the preparation time ends. As a result, the user can recognize the change in sound and determine whether or not it can be used, thereby improving usability.

  Further, in the present invention, the operation of the switches 3 and 4 provided in the main body case 1 starts the driving of the thermoelectric conversion element 44 and the blowing unit 31, and when a predetermined time has elapsed, the driving of the blowing unit 31 is limited. Control was performed so that driving of the thermoelectric conversion element 44 and the air blowing means 31 was stopped after a predetermined time. As a result, the cooling preparation time of the head 2 can be shortened and the power consumption of the entire instrument can be reduced by restricting the driving of the blowing means 31. Further, if the air blowing means 31 includes a motor 66 and a fan 67 attached to the rotating shaft thereof, the cooling preparation time of the head 2 can be shortened, and the air blowing means 31 becomes low noise during use time, and the user is comfortable. You can take care of your skin. In addition, during the cooling preparation time, if the sound generated by the driving of the air blowing means 31 is completed, the sound becomes low output driving when the preparation time ends. As a result, the user can recognize the change in sound and determine whether or not it can be used, thereby improving usability.

  When the above-described series of operations is continuously repeated a predetermined number of times, the thermoelectric conversion element 44 and the air blowing means 31 continue to be driven even after a predetermined time has elapsed, and when the predetermined time has elapsed, the thermoelectric conversion element 44 and the air blowing means 31 are continued. Control was performed to stop the driving of As a result, it is possible to cause the user to recognize that the usage is incorrect (continuous use) by generating a state different from the normal use state. Even when continuously used, it is possible to promote heat dissipation and cool the head 2 by continuously driving the air blowing means 31.

  When the above series of operations is continuously repeated a predetermined number of times, the thermoelectric conversion element 44 and the air blowing means 31 continue to be driven even after a predetermined time has elapsed, and when the predetermined time has elapsed, the driving of the thermoelectric conversion element 44 is stopped. In addition, the driving of the air blowing means 31 was controlled to stop when a predetermined time passed. As a result, even after the skin care is completed, the air blowing means 31 can still be driven. Therefore, when the next user cleans the skin, the head 2 tends to have a desired cooling temperature.

  After the driving of the thermoelectric conversion element 44 was stopped, the driving of the blowing unit 31 was started again, and after a predetermined time had elapsed, the driving of the blowing unit 31 was stopped. As a result, even after the skin care is completed, the air blowing means 31 can still be driven. Therefore, when the next user cleans the skin, the head 2 tends to have a desired cooling temperature.

  When the driving of the thermoelectric conversion element 44 and the air blowing means 31 is started, the light emitting display means 6d is driven to blink so that the user can recognize that it is a preparation time, and a predetermined time has passed. When the driving of the blower unit 31 is stopped, the light emitting display unit 6d is driven to turn on so that the user can recognize that the preparation time is over and the usable time is reached. Further, when the drive of the light emitting display means 6d is stopped when the drive of the thermoelectric conversion element 44 and the blower means 31 is stopped after a predetermined time has elapsed, the user is made aware that the use of the beauty tool has been stopped. be able to.

  By driving the sound generation display means (buzzer) 95 when the driving of the air blowing means 31 is stopped after a predetermined time has elapsed, the user can recognize that the preparation time is over and the usable time is reached. . Here, driving the sound generation display means (buzzer) 95 when the driving of the blowing means 31 is stopped means that the driving of the blowing means 31 is stopped just after the driving of the blowing means 31 or a little time from the stop of the blowing means 31. For example, this includes driving the sound generation display means (buzzer) 95 after one second.

  In the present invention, the inside of the main body case 1 is divided into the ventilation area 13 and the electrical component area 15, and the air blowing means 31 and the heat sink 30 for heat dissipation are arranged inside the ventilation area 13. In addition, a control circuit 87 for controlling the driving of the thermoelectric conversion element 44 of the cooling unit 12 is disposed inside the electrical component area 15 partitioned by the cover body 18. As described above, when the control circuit 87 is arranged in the electrical component area 15, the liquid adheres to the substrate of the control circuit 87 even if liquid such as skin lotion enters the inside of the main body case 1 when performing skin cooling. Can be prevented. In addition, it is possible to prevent the control circuit 87 from being heated by the warm air after heat exchange or the radiant heat emitted from the heat sink 30, thereby preventing the electronic component from being overheated. Therefore, there is no room for short circuit or malfunction due to adhesion of liquid such as skin lotion, and there is no room for failure or burn due to overheating of electronic parts, and it is possible to provide a beauty instrument with excellent safety and reliability.

  When the heat sink 30 is vertically disposed over the outer surface of the cover body 18 from the cooling unit 12 disposed at the upper part of the main body case 1, the contact between the cooling air and the heat sink 30 is increased and emitted from the thermoelectric conversion element 44. Heat can be effectively discharged out of the main body case 1. In addition, since a part of the outer surface of the cover body 18 is covered with the heat sink 30, the liquid such as lotion that has entered the ventilation area 13 together with the cooling air is blocked by the heat sink 30, and the liquid adheres to the outer surface of the cover body 18. Can be avoided as much as possible.

  When the heat sink 30 is configured by the plate-shaped sink base 54 and a large number of fins 55 protruding from the sink base 54, and the upper part of the outer surface of the cover body 18 is covered by the sink base 54, the inside of the ventilation area 13 is formed. The liquid such as lotion that has entered can be blocked more effectively by the plate-shaped sink base 54. Therefore, it is possible to more reliably prevent the liquid from adhering to the cover body 18 and prevent the circuit board 14 and the electronic components from being damaged.

  If the stepped portion 57 is provided in the middle of the sink base 54, liquid such as lotion that has entered between the fins 55 of the heat sink 30 may be received by the stepped portion 57 and temporarily stay in the stepped portion 57. it can. Therefore, it is possible to prevent the liquid that has entered between the fins 55 from passing through the heat sink 30 together with the cooling air and adhering to the blowing means 31 disposed on the downstream side of the ventilation area 13. Further, a part of the liquid staying in the stepped portion 57 can be heated and evaporated by the heat of the sink base 54 while flowing down along the sink base 54.

  When the heat exchange passage 60 provided between the sink base 54 and the peripheral wall of the main body case 1 is formed so that the cross-sectional area of the passage decreases from the upper part to the lower part of the heat sink 30, The flow rate can be increased. Therefore, the passage speed of the cooling air passing between the fins 55 can be increased, the contact opportunity between the fins 55 and the cooling air can be increased, and the heat exchange efficiency of the heat sink 30 can be increased. As a result, the heat released from the thermoelectric conversion element 44 can be discharged more effectively. For example, even when the beauty tool is used over an appropriate usage time, the beauty tool falls into an overheated state. Can be secured to secure and protect users' safety.

  When a ventilation gap 63 smaller than the gap between the front and rear of the heat exchange passage 60 is provided between the sink base 54 and the cover body 18, the heat layer that conducts heat from the sink base 54 to the cover body 18 flows through the ventilation gap 63. Can be shut off. Similarly, the radiation heat of the sink base 54 reaching the cover body 18 can be blocked by the air layer flowing through the ventilation gap 63, and the electronic components in the electric component area 15 can be protected from the heat of the heat sink 30. Moreover, since the clearance dimension of the ventilation gap 63 is made smaller than the front and rear clearances of the heat exchange passage 60, the amount of air passing through the ventilation gap 63 can be limited. Therefore, most of the cooling air sucked into the air blowing means 31 is made to flow along the heat exchange passage 60, and the heat exchange between the cooling air and the heat sink 30 is effectively performed, and then the heat sink 30 moves toward the cover body 18. Heat transfer can be prevented.

  When the vibrator 33 is fixed by the pressing wall 22 of the cover body 18 fastened and fixed to the main body case 1, the screws and fixing structure for fixing the vibrator 33 can be omitted, and the structure can be simplified correspondingly. Further, since the outer surface of the vibrator 33 is covered with the pressing wall 22 provided on the cover body 18, it is possible to prevent the liquid such as the skin lotion that has entered the ventilation area 13 from being blocked by the pressing wall 22 and attached to the vibrator 33.

  When the diverting body 32 is disposed below the blowing means 31 and the heat exchange air supplied from the blowing means 31 is diverted and guided toward the discharge port 62 by the diverting body 32, the heat exchange air is supplied to the body case 1. It can be effectively discharged outside. Thereby, since it is possible to eliminate high-temperature air after heat exchange in the ventilation area 13, the heat radiation effect in the heat sink 30 can be promoted, and the heat exchange efficiency can be further improved.

  When a power feeding socket 75 is disposed adjacent to the diverting body 32 and the peripheral surface on the ventilation area 13 side is covered with the diverting body 32, liquid such as lotion that has reached the vicinity of the socket 75 is transferred to the socket. It is possible to prevent the deflecting body 32 from adhering to the 75, the power feed lead 77 and the like. Therefore, it is possible to prevent troubles and accidents associated with the adhesion of liquid around the socket 75.

  When the gap between the power supply lead 77 led out from the socket 75 and the lead opening 78 opened in the cover body 18 is sealed with the packing 79 and a part of the turning body 32 is received by the packing 79, The movement can be damped by packing 79. Therefore, it can suppress that the direction change body 32 receives the vibration of the ventilation means 31 and the vibrator 33, and vibrates. In addition, since it is possible to eliminate the occurrence of contact noise due to the turning body 32 coming into contact with the cover body 18, it is possible to reduce driving noise when using a beauty tool and improve quietness.

  According to the beauty tool in which the contact electrode 39 of the head 2 is used as the first electrode 9 for ion introduction or ion extraction, and the second electrode 10 for ion introduction or ion extraction is arranged on the outer surface of the main body case 1, The skin can be effectively penetrated into the skin by the introduction action, or fine dirt on the skin can be effectively removed by the action of deriving ions.

In that case, most of the cooling unit 12 is accommodated in the main body case 1. The head case 36 has a name different from that of the main body case 1, but can also be seen as a part of the main body case 1. The head 2 includes a contact plate 39 in which a titanium plate is formed in a dish shape, and a holding ring 40 that fixes and holds the peripheral portion of the contact plate 39. As shown in FIG. 6, the holding ring 40 is fitted on the outer surface of the protruding end of the head case 36 and fixed with screws 41. Sealing between the head case 36 and the front case 1a and between the contact plate 39 and the head case 36 are performed by seal rings 26 and 27, respectively. The contact plate 39 is not limited to titanium, but may be other metal such as aluminum as long as current can be passed and heat conduction is good.

  The cooling unit 37 includes a Peltier element (thermoelectric conversion element) 44, a cooling block 45 and a heating block 46 that are in close contact with the low temperature side and the high temperature side with the element 44 interposed therebetween, and these three units 44, 45, The cooling unit holder 47 that supports the cooling unit 46 is used. The cooling block 45 and the heating block 46 are in close contact with the Peltier element 44 via a heat transfer sheet 48. The heat transfer sheet 48 is configured by coating silicon on both the front and back surfaces of an aluminum sheet. The Peltier element (thermoelectric conversion element) 44, the cooling block 45, and the heating block 46 are fastened together with the thermal insulator 50 disposed between the blocks 45 and 46 by screws 49 inserted into the cooling unit holder 47. It is unitized (see FIG. 5).

  As shown in FIG. 9, the cooling unit holder 47 is fixed to the front case 1a with four screws 51 so that the front end surface of the cooling block 45 is in close contact with the inner surface of the contact plate 39 so that the cooling unit 37 can be It is fixed to the case 1a and the head case 36. The rear end of the thermal block 46 in this state enters the rear case 1b side from the joint surface of the front and rear cases 1a and 1b (see FIG. 6).

  The cooling block 45 and the heating block 46 are each made of an aluminum die-cast molded product. In order to more effectively release the heat generated in the Peltier element (thermoelectric conversion element) 44, the volume (mass) of the heating block 46 is made sufficiently larger than the volume (mass) of the cooling block 45, and the unit The amount of heat conduction per hour (heat capacity) is increased. Thereby, the heat generated on the high temperature surface side of the Peltier element 44 can be effectively conducted to the heat sink 30 fixed to the rear end of the thermal block 46 to promote the heat radiation action. On the other hand, the surface area of the heat block 46 is made sufficiently larger than the surface area of the heat block 45 to increase the heat radiation amount per unit time in the heat block 46. In addition, the volume (mass) of the heat sink 30 is made larger than the volume (mass) of the thermal block 46 to increase the heat conduction amount (heat capacity) per unit time. Thereby, the heat generated on the high temperature surface side of the Peltier element (thermoelectric conversion element) 44 can be stored by the heat capacities of both the heat block 46 and the heat sink 30, so that the driving of the blowing means 31 is intentionally stopped. be able to. Alternatively, if the heat capacity is small, when the motor 66 for the air blowing means 31 is stopped carelessly, the low temperature surface side of the Peltier element (thermoelectric conversion element) 44 becomes hot, and the contact plate 39 becomes hot accordingly. There are times when it makes me feel uncomfortable, but it can be prevented. Furthermore, since the surface area of the heat sink 30 is larger than the surface area of the thermal block 46, the heat dissipation effect is further enhanced. The heat block 46 and the heat sink 30 may be an integral aluminum die cast product. In order to improve the heat dissipation efficiency, a plurality of fins can be provided around the thermal block 46.

  As shown in FIGS. 5 and 6, the heat sink 30 is an aluminum die-cast molded product integrally including a plate-shaped sink base 54 and a large number of fins 55 protruding from the rear surface of the sink base 54. Consists of. The heat sink 30 is fastened so as not to be separated by screws 56 screwed into the heat block 46 in a contact state where the upper part of the sink base 54 is engaged with the heat block 46 so as not to be relatively movable. A stepped portion 57 that is inclined obliquely downward is formed in the upper and lower middle portion of the sink base 54. Therefore, the plate-like portion 54b below the stepped portion 57 is higher than the plate-like portion 54a above the stepped portion 57. It is approaching the rear case 1b. The connection between the cooling unit 12 and the heat sink 30 is not limited to the above-described structure in which the sink base 54 is directly fixed to the thermal block 46, and the heat sink 30 is kept in a state where the facing surfaces of the thermal block 46 and the sink base 54 are in contact with each other. Can be fixed to the front case 1a.

  In order to increase the chance of contact between the fins 55 and the cooling air and increase the heat exchange efficiency, the heat sink 30 is formed vertically along the ventilation area 13. Further, the passage cross-sectional area of the heat exchange passage 60 sandwiched between the sink base 54 and the peripheral wall of the rear case 1b facing the base 54 is made smaller from the heat sink 30 side toward the air blowing means 31 side. Yes. More specifically, the peripheral wall of the rear case 1 b facing the sink base 54 is recessed so as to approach the sink base 54, and the passage cross-sectional area of the heat exchange passage 60 is changed from the upper end side to the lower end side of the sink base 54. It is formed in a constricted shape downward. Incidentally, the distance between the lower end side of the sink base 54 and the peripheral wall of the rear case 1b is made smaller than the distance between the upper end side of the sink base 54 and the peripheral wall of the rear case 1b, so that the passage sectional area of the heat exchange passage 60 is increased. It can be formed in a constricted shape toward the blowing means 31 side.

  As described above, the amount of heat released by the fins 55 can be increased by increasing the vertical length of the heat sink 30. Furthermore, by forming the heat exchange passage 60 in a constricted shape, the passage speed of the cooling air passing between the fins 55 can be increased, and the chance of contact between the fins 55 and the cooling air can be increased. The heat exchange efficiency of 30 can be increased. Since the heat sink 30 is arranged vertically from the cooling unit 12 to the outer surface of the cover body 18, the majority lower part of the lower plate-like part 54b covers the outside of the upper rear surface of the cover body 18 (FIGS. 1 and 6). reference). Therefore, the lotion that has entered through the suction port 61 is shielded by the sink base 54, and the lotion can be well prevented from adhering to the cover body 18. Further, by providing the stepped portion 57 in the middle part of the sink base 54, the lotion flowing down along the upper plate-like portion 54a can be received by the stepped portion 57 and retained therein.

  A group of cooling air suction ports 61 are opened in the peripheral wall of the rear case 1 b facing the upper plate-like portion 54 a of the sink base 54. Further, a group of discharge ports 62 for discharging the warm air after heat exchange is opened in the peripheral wall on the lower side of the rear case 1b. Thus, if the structure which discharges warm air from the lower part side of main body case 1 is employ | adopted, since warm air can be discharged in the position away from the skin of cooling object, it does not give a user discomfort. In the present embodiment, the suction port 61 and the discharge port 62 are opened toward the side (rear), but the suction port 61 is opened upward and the discharge port 62 is opened downward. It may be a thing.

  Between the lower plate-like portion 54b described above and the cover body 18, a ventilation gap 63 smaller than the front and rear gaps of the heat exchange passage 60 is secured, and therefore a part of the cooling air in the ventilation area 13 is secured. Is sucked into the blowing means 31 through the ventilation gap 63. Thus, by ensuring the ventilation gap 63, it is possible to prevent the heat of the sink base 54 from being conducted to the cover body 18. In addition, since the gap size of the ventilation gap 63 is small, most of the cooling air sucked into the blower unit 31 can flow along the heat exchange passage 60 to effectively perform heat exchange.

  The air blowing means 31 includes a fan case 65 that also serves as a motor holder, a motor 66 that is fixed to the upper half of the fan case 65, and an axial-flow fan 67 that is fixed to the output shaft thereof. The fan 67 is rotated and stopped by controlling the drive current from the control circuit 87 to the motor 66 and switching the output of the motor 66. The air blowing means 31 is not limited to the axial flow type fan, but may be a centrifugal type fan. Moreover, the ventilation means 31 may provide a discharge electrode and a counter electrode, and may generate an ion wind by applying a high voltage to both. In this case, the blowing power is small, but almost no sound is generated. The air in the ventilation area 13 is sent downward toward the deflector 32. The fan case 65 is fixed to the screw boss 24 described above with screws 71 (see FIG. 9). The periphery of the fan case 65 is vertically divided by a partition wall 72 projecting from the cover body 18 and the rear case 1b so as to face each other (see FIG. 7). Therefore, after the heat exchange sent from the blowing means 31 is completed. Does not flow back to the heat exchange passage 60 side.

  As shown in FIG. 5, the deflecting body 32 is formed of a cover-like structure whose front and bottom surfaces are open, and the outer shape viewed from the rear side is formed in an inverted convex shape (see FIG. 9). As shown in FIG. 7, a turning wall 68 is formed in a downwardly inclined manner in the wide portion on the upper half side of the turning body 32 facing the discharge port 62. A contact rib 69 is provided on the inner surface of the inclined portion at the upper end of the turning wall 68. A partially spherical turning surface 70 is formed at the lower end of the recess 23 described above, and heat exchange air supplied from the blowing means 31 by this turning surface 70 is shared with the turning wall 68. Then, it is possible to guide the direction of change toward the discharge port 62. In the above embodiment, the suction port 61 is formed in the upper portion of the main body case 1 and the discharge port 62 is formed in the lower portion of the main body case 1 so that the heat exchange (cooling) air in the ventilation area 13 is sent downward. A discharge port 62 may be formed in the upper part of the case 1 and a suction port 61 may be formed in the lower part of the main body case 1 so that heat exchange (cooling) air in the ventilation area 13 may be supplied upward. Of course, the blowing direction of the blowing means 31 in that case is set in reverse.

  A power feeding socket 75 is arranged on the inner surfaces of the lower ends of the front and rear cases 1a and 1b, and the circumferential surface on the side of the ventilation area 13 is covered with a deflecting body 32. The diverter 32 and the socket 75 are fixed to each other by using the lower two screws 8 that fasten the front and rear cases 1a and 1b, and are integrated with the main body case 1. As shown in FIG. 7, two connection pins 76 for connecting a power supply plug 74 led out from the power adapter are provided in the power supply socket 75, and the power supply leads connected to the connection pins 76 are provided. 77 is derived from the upper end of the socket 75. The power supply lead 77 is introduced into the electrical component area 15 through a lead opening 78 opened in the cover body 18 and connected to the circuit board 14. A gap between the power supply lead 77 and the lead opening 78 is sealed with a rubber packing 79 attached to the lead opening 78.

  As described above, the deflector 32 is fixed to the main body case 1. Therefore, it vibrates in response to the vibration of the blowing means 31 and the vibration of the vibrator 33, and the upper opening edge may contact the cover body 18 to generate contact noise. In order to prevent the generation of such noise, the projecting end of the contact rib 69 of the deflector 32 is received by the rear end surface of the packing 79 to prevent the deflector 32 from coming into contact with the cover body 18. Can be absorbed by the packing 79 (see the enlarged view of FIG. 7).

  The vibrator 33 arranged inside the front case 1a is composed of a motor 82 and an eccentric weight 83 fixed to the output shaft thereof, and generates vibration by the rotational drive of the motor 82. The vibrator 33 also serves as vibration display means that can display the state of the appliance by vibration as will be described later. A rubber mounting seat 84 is fixed inside the front case 1a, and the motor 82 fitted in the mounting seat 84 is fixed and held by the pressing wall 22 provided on the cover body 18 so as not to be separated (see FIG. 6).

  As described above, the following components are accommodated in the electrical component area 15. The energization (drive) state of the Peltier element (thermoelectric conversion element) 44, the energization (drive) state of the vibrator (vibration display means) 33 to the motor 82, and the energization of the motor 66 (blower means 31) for the fan 67 (Driving) state, energizing (driving) state to the buzzer 95 as a sound generation display means, energizing (driving) states to the mode indicator lamps (light emitting display means) 6a, 6b, 6c, 6d, and the strength indicator lamp ( Various switches for sending command signals to the control circuit 87 and the control circuit 87 for controlling the energization (drive) state of the light emitting display means) 7a and 7b and the energization (drive) state of the first electrode 9 and the second electrode 10 3b, 4b, 5b, a circuit board 14 on which they are mounted, and the like are accommodated. One output lead 89 connected to the control circuit 87 is connected to a connection terminal 91 integrally provided with an elastically deformable contact portion 93 provided inside the head case 36 as shown in FIG. The output leads 90 are connected to connection terminals 92 fixed to the left and right sides of the fan case 65 as shown in FIG. The former connection terminal 91 is made of a metal plate, and its free end side, that is, the contact portion 93 side is fixed to be elastically deformable by using a screw 35 for fastening the head case 36 to the front case 1a.

  In a state in which the head 2 is assembled to the head case 36, the contact portion 93 provided on the distal end side of the arm portion of the connection terminal 91 is in close contact with the inner surface of the contact plate 39 that also serves as the first electrode 9. . As described above, when the connection terminal 91 and the first electrode 9 are conducted through the elastically deformable contact portion 93, even if a dimensional error occurs between the fixed portion of the connection terminal 91 and the first electrode 9, A dimension error is absorbed by the arm part of the connection terminal 91, and an electrical connection state can be maintained favorable. In particular, when using a beauty tool, the head 2 is cooled or returned to room temperature, so the distance between the components is likely to change due to the temperature change. Even in such a case, the electrical connection state is good. Can be maintained.

  The connection terminal 92 for the second electrode 10 is fixed using a screw 71 for fixing the fan case 65, and the second electrode 10 and the connection terminal 92 press and urge the second electrode 10. The spring 94 is used for conduction. When the connection terminal 92 and the second electrode 10 are conducted through a coiled spring (elastic body) 94, even if a dimensional error occurs between the connection terminal 92 and the second electrode 10, the dimensional error is reduced by the spring 94. Therefore, it is possible to maintain a good electrical connection state.

  The connection terminal 91 can be formed as a fixed portion by bending the base end portion of the metal wire into an L shape, and the other end can be formed as a coil-shaped contact portion 93 having spring properties. In that case, the fixing part is fixed with the screw 35, the contact part 93 on the free end side is assembled to the first electrode 9 in a pressed state, and the connection terminal 91 and the first electrode 9 are made conductive. Even in the case of this structure, even if a dimensional error occurs between the fixed portion of the connection terminal 91 and the first electrode 9, a good electrical connection state can be maintained by elastic contact.

  In FIG. 9, reference numeral 101 denotes a power supply lead for the Peltier element (thermoelectric conversion element) 44, reference numeral 102 denotes a power supply lead for the blowing means 31, and reference numeral 103 denotes a power supply lead for the vibrator 33. The lead openings of each of the power supply leads 101, 102, and 103 and the lead openings of the output leads 89 and 90 described above are sealed with packing in the same manner as the power supply lead 77.

  In the beauty device configured as described above, when the power button 3 is turned on, a driving current is supplied from the control circuit 87, the motor 82 of the vibrator 33 is activated, and after a predetermined time (for example, 1 second), The first mode is entered, and the instrument enters a standby state. Since the vibrator 33 is driven when the power button 3 is turned on, it can be confirmed that the instrument is activated by the touch of the hand, which leads to a sense of security for the user.

  The mode button 4 can be switched from the first mode to the fourth mode every time it is turned on. In addition, every time the mode button 4 is turned on, “beep”, “beep” and buzzer 95 sounds are controlled. In the first mode (cleansing mode), a voltage with the first electrode 9 having a positive polarity and the second electrode 10 having a negative polarity is applied. In this state, the cosmetic cotton mat 97 (see FIG. 3) impregnated with lotion is applied to the outer surface of the contact plate 39 and the periphery thereof is fixed by the cap 98 that is press-fitted to the head 2. When the body case 1 including 10 is held by hand and the cotton mat 97 (first electrode 9) is applied to the skin such as the face, ions can be derived and fine skin dirt can be removed. The control circuit 87 also energizes the mode indicator lamp (light emission display means) 6a, and controls the mode indicator lamp 6a to blink, turn on or off.

  When the power button 3 is turned on and the mode button 4 is turned on to switch to the first mode, a weak current (pulse signal) for detecting a human body having a long off time is sent to the first electrode 9. This state is a standby state of the instrument (at this time, the mode indicator lamp 6a is blinking). If the body case 1 including the second electrode 10 is held by hand and the cotton mat 97 (first electrode 9) is applied to the skin, the weak current (pulse signal) output from the first electrode 9 The human body detection signal determination circuit of the control circuit 87 is turned on, and the signal is sent to the microcomputer to confirm the human body detection. As a result, the control circuit 87 enters a use state (at this time, the mode indicator lamp 6a is turned on) by sending a pulse signal for skin energization with a short off time to the first electrode 9. That is, the first electrode 9 and the second electrode 10 are both human body detection sensors and electrode heads for energizing the skin. In the first mode, the control circuit 87 starts measuring time after the human body is detected (the above-mentioned main body case 1 is gripped by hand and the cotton mat 97 (first electrode 9) is applied to the skin). When intermittent contact is repeated and the cumulative time of human body detection reaches a predetermined time (for example, 5 minutes), power supply to the first electrode 9 and the second electrode 10 is automatically stopped. In synchronization with this, the mode indicator lamp 6a is turned off. The control circuit 87 also controls the energization state of the buzzer 95. When the power button 3 is turned on, the buzzer 95 sounds once and can confirm the operation with a sound. When the accumulated time of human body detection is 5 minutes, that is, when the first mode is ended, the buzzer 95 is extended twice for a long time to notify the end of maintenance with a “peep” and an end sound. At this time, the standby state of the instrument is also stopped and the power is turned off.

  In the first mode, when the power button 3 is pressed again and the power is turned off in the standby state or human body detection state with a wide pulse interval, or the power plug 74 is pulled out from the instrument and the power is turned off. In this case, the first mode is stored, and even if the power button 3 is pressed again and turned on, the first mode is started. When the energization of the first electrode 9 and the second electrode 10 is automatically stopped when the cumulative time of human body detection is 5 minutes of the specified time, the control circuit 87 stores the second mode, When the button 3 is turned on, the second mode is started without turning on the mode button 4.

  In the second mode (vibration mode), a voltage whose polarity is alternately switched is applied to the first electrode 9 and the second electrode 10, and the vibrator 33 is driven intermittently. Thereby, if the head 2 is applied to the skin, the skin can be loosened. The control circuit 87 also energizes the mode indicator lamp (light emission display means) 6b, and controls the mode indicator lamp 6b to blink, turn on or off.

  When the power button 3 is turned on and then the mode button 4 is turned on to switch to the second mode, a standby state with a wide pulse interval as in the first mode (the mode indicator lamp 6b is blinking at this time) However, if the body case 1 including the second electrode 10 is grasped by hand and the first electrode 9 is applied to the skin, the human body is detected in the same manner as in the first mode, and the use state with a narrow pulse interval is the same as in the first mode. (At this time, the mode indicator lamp 6b is turned on). In the first mode, when the cumulative time of human body detection is 5 minutes and the energization to the first electrode 9 and the second electrode 10 is automatically stopped, the control circuit 87 stores the second mode. Therefore, the second mode starts without turning on the mode button 4.

  In the second mode, the control circuit 87 starts timing after the human body is detected, repeats intermittent contact with the skin, and automatically reaches the predetermined time (for example, 5 minutes) when the cumulative time of human body detection reaches a predetermined time (for example, 5 minutes). The energization to the first electrode 9 and the second electrode 10 and the energization to the vibrator 33 are stopped. In synchronization with this, the mode indicator lamp 6b is turned off. The control circuit 87 also controls the energization state of the buzzer 95. When the power button 3 is turned on, the buzzer 95 sounds once and can confirm the operation with a sound. When the accumulated time of human body detection is 5 minutes, that is, when the second mode is finished, the buzzer 95 is extended twice and “Peep” and the end sound are used to notify the end of the maintenance. At this time, the standby state of the instrument is also stopped and the power is turned off.

  In the second mode, when the power button 3 is pressed again and the power is turned off in the standby state or human body detection state with a wide pulse interval, or the power plug 74 is pulled out from the instrument and the power is turned off. In this case, the first mode is stored, and if the power button 3 is pressed again and turned on, the first mode is started. When the cumulative time of human body detection is 5 minutes of the specified time and the energization to the first electrode 9 and the second electrode 10 and the energization to the vibrator 33 are automatically stopped, the control circuit 87 stores the third mode. Therefore, when the power button 3 is turned on, the third mode is started without turning on the mode button 4.

  In the third mode (moisture penetration mode), a voltage with the first electrode 9 having a negative polarity and the second electrode 10 having a positive polarity is applied. In this manner, if the cotton mat 97 for cosmetics impregnated with lotion is fixed to the head 2 and the cotton mat 97 (first electrode 9) is applied to the skin, ions can be introduced, and moisturizing ingredients can be applied to the skin. The beauty effect can be enhanced. The control circuit 87 energizes the mode indicator lamp (light emission display means) 6c, and controls the mode indicator lamp 6c to blink, turn on or off.

  When the power button 3 is turned on and then the mode button 4 is turned on to switch to the third mode, a standby state with a wide pulse interval similar to the first mode (the mode indicator lamp 6c is blinking at this time) is set. However, if the body case 1 including the second electrode 10 is grasped by hand and the cotton mat 97 (first electrode 9) is applied to the skin, the human body is detected in the same manner as in the first mode, and the same pulse as in the first mode is detected. The use state is narrow (the mode indicator lamp 6c is lit at this time). In the second mode, when the cumulative time of human body detection is 5 minutes and the energization to the first electrode 9 and the second electrode 10 is automatically stopped, the control circuit 87 stores the third mode. Therefore, the third mode starts without turning on the mode button 4.

  In the third mode, the control circuit 87 starts timing after the human body is detected, repeats intermittent contact with the skin, and automatically starts when the cumulative time of human body detection reaches a predetermined time (for example, 5 minutes). Current supply to the first electrode 9 and the second electrode 10 is stopped. In synchronization with this, the mode indicator lamp 6c is turned off. The control circuit 87 also controls the energization state of the buzzer 95. When the power button 3 is turned on, the buzzer 95 sounds once and a short beep makes it possible to confirm the operation. . When the cumulative time of human body detection reaches 5 minutes, that is, when the third mode is ended, the buzzer 95 is extended twice and “Peep” and the end sound are used to notify the end of the maintenance. At this time, the standby state of the instrument is also stopped and the power is turned off.

  In the third mode, when the power button 3 is pressed again and the power is turned off in the standby state or human body detection state where the pulse interval is wide, or the power plug 74 is pulled out from the instrument and the power is turned off. In this case, the first mode is stored, and even if the power button 3 is pressed again and turned on, the first mode is started. When the cumulative time of human body detection is 5 minutes of the specified time and the energization to the first electrode 9 and the second electrode 10 is automatically stopped, the control circuit 87 stores the fourth mode, so the power supply When the button 3 is turned on, the fourth mode is started without turning on the mode button 4.

  In the first to third modes, the potential applied to the first and second electrodes 9 and 10 can be switched between strong and weak by turning on the strength button 5. In the first embodiment, in the first to third modes, in order to energize the skin surface, the main body case 1 is grasped with one hand, the hand is brought into contact with the second electrode 10, and then the head 2. Needs to be in contact with the skin surface such as the face skin, but the head 2 is divided into two half-moons, one of which is the first electrode 9 and the other is the second electrode 10. It is possible to energize the first and second electrodes 9 and 10 simply by placing the head 2 on the skin surface without paying attention to the above. When the power button 3 is turned on again or when a predetermined time (for example, 30 seconds) has elapsed since the power button 3 was turned on, the power is turned off. The vibrator 33 may be provided with a dedicated drive switch so that it can be driven arbitrarily. Thereby, the user can arbitrarily perform vibration massage on the skin surface.

  In the fourth mode (cool mode = cooling operation), the Peltier element (thermoelectric conversion element) 44 is driven. Thereby, if the head 2 is applied to skin, a skin surface can be cooled. The control circuit 87 energizes the mode indicator lamp (light emission display means) 6d, and controls the mode indicator lamp 6d to blink, turn on or off. The control circuit 87 also controls driving of the buzzer 95.

  In FIG. 10, when the power button 3 is turned on and then the mode button 4 is turned on to switch to the fourth mode, the control circuit 87 first turns the air blowing means 31 together with the Peltier element (thermoelectric conversion element) 44. Drive (timing a). The Peltier element 44 and the air blowing means 31 are driven for a predetermined time A (for example, 90 seconds). During a predetermined time A, the mode indicator lamp (light emitting display means) 6d made of LED is in a blinking state. After the elapse of the predetermined time A (timing b), the Peltier element 44 continues to be driven as it is, and the blowing means 31 stops driving. When a predetermined time (for example, 1 second) elapses from the timing b, the buzzer (sound generation display means) 95 that notifies the completion of preparation is sounded twice with a short sound. At this time, the vibrator (vibration display means) 33 is controlled to be simultaneously driven for a predetermined time. This allows the user to recognize the completion of preparation by sound and vibration. Either one or both of the buzzer (sound display means) 95 and the vibrator (vibration display means) 33 can be driven to make the user aware of the completion of preparation.

  The driving of the Peltier element 44 alone without the driving of the air blowing means 31 is performed for a predetermined time B (for example, 90 seconds). The predetermined time A is a cooling preparation time, and the cooling time of the head 2 can be shortened by driving the air blowing means 31. Further, when the predetermined time B elapses, the driving of the Peltier element 44 is stopped and the blowing means 31 is driven again (timing c). The predetermined time B is a usage time for actually performing the cleaning with the cooled head 2, and since the driving of the air blowing means 31 is stopped, the user can comfortably clean the skin. In addition, during the cooling preparation time, the sound generated by the rotation of the air blowing means 31 is stopped when the preparation time ends, so that the user can recognize the change in the sound and determine whether it can be used. Usability is improved. Timing c is when the maintenance is completed, and the buzzer 95 that notifies the completion of the maintenance is driven twice with a long sound of “Peepy”. Thus, by performing the pronunciation that tells the end of the cooling use time, the user can finish the use of the beauty device with peace of mind. The vibrator (vibration display means) 33 can be driven for a predetermined time (for example, 1 second) at the timing c when the maintenance is completed, and a completion display by vibration can be displayed to the user. As a result, it is possible to easily recognize the completion of care for a user who is deaf. In addition, at the predetermined time B, the buzzer 95 is driven to generate a sound “beep” once before the end of the predetermined time B (drive of the Peltier element 44) (for example, 5 seconds before). As a result, the user can recognize the end of the maintenance in advance by sound. Further, at a predetermined time B, the vibrator (vibration display means) 33 is controlled to be driven for a predetermined time (for example, 0.5 seconds) before the end of the predetermined time B (the driving of the Peltier element 44) (for example, 5 seconds before). ing. Thereby, the user can recognize the end of the maintenance by vibration in advance. In this embodiment, the sound and vibration are displayed before the end of the predetermined time B, but only one of them may be displayed.

  When a predetermined time C (for example, 30 seconds) elapses after the blowing unit 31 is driven again, the driving of the blowing unit 31 is stopped (timing d). Even if the skin care is finished by the predetermined time C, the air blowing means 31 can still be driven, so that the head 2 has a desired cooling temperature when the next user performs skin care. Cheap. The blowing means 31 at this time may have the same driving state as the driving state for the predetermined time A, or a driving state larger than that, that is, the rotational speed of the blowing means 31 is higher than the rotational speed for the predetermined time. You may set large. Although the mode indicator lamp 6d is blinking at the predetermined time A, the mode indicator lamp 6d is turned on at the predetermined time B after the timing b. Further, after the timing c, the mode indicator lamp 6d is turned off. As described above, in this embodiment, a total of 210 seconds is required from the switch-on to the end of the operation, but a series of cooling operations are automatically performed by the control circuit 87 according to the program. In addition, the operation | movement for the predetermined time C which drives only the ventilation means 31 can also be skipped.

  In any mode of the first mode, the second mode, the third mode, and the fourth mode, when the power button 3 is pressed again during the series of operation time and the power is turned off, or the power supply plug 74 is operated. Is pulled out from the instrument and the power is turned off, the operation starts in the first mode if the power button 3 is pushed and turned on. In addition, the control circuit 87 controls to automatically turn off the power if the human body detection is not performed for a predetermined time (for example, 30 seconds) in the first mode, the second mode, and the third mode (auto-off control). is doing. In the case of auto-off in the first mode, if the next power switch (switch) 3 is turned on, the operation starts from the second mode. In the case of auto-off in the second mode, the next power switch (switch) is started. If 3 is turned on, control starts from the third mode. If auto power off is performed in the third mode, control is performed to start from the fourth mode if the next power switch 3 is turned on. .

  When a series of cooling operations from timings a to d is completed, the standby state of the instrument is also stopped and the power is turned off. At this time, the first mode is stored in the control circuit 87. If the power button (switch) 3 is subsequently turned on, the control circuit 87 starts from the first mode. When a series of cooling operations from timings a to d is completed, the control circuit 87 counts and stores the first cooling operation. If the power button (switch) 3 is turned on, the mode button (switch) 4 is turned on three times to select the fourth mode (cool mode = cooling operation), the operation starts again from timing a, and timing b , Timing c, timing d, etc., a series of operations similar to the first time are automatically performed. When the second series of cooling operations from timing a to d is completed, the standby state of the instrument is also stopped and the power is turned off. At this time, the first mode is stored in the control circuit 87. If the power button (switch) 3 is subsequently turned on, the control circuit 87 starts from the first mode. When a series of cooling operations from timings a to d is completed, the control circuit 87 counts and stores the second cooling operation. If the power button (switch) 3 is turned on and the mode button (switch) 4 is turned on three times to select the third mode (cool mode = cooling operation), the same operation starts again from timing a. When the above-described series of cooling operations are continuously repeated a predetermined number of times, in the present embodiment, the following operations are performed during the third cooling operation.

  That is, as shown in FIG. 11, when the power button (switch) 3 is turned on and then the mode button (switch) 4 is turned on three times to switch to the fourth mode (cool mode = cooling operation), First, the control circuit 87 drives the blower unit 31 together with the Peltier element (thermoelectric conversion element) 44 (timing a). The Peltier element 44 and the air blowing means 31 are driven for a predetermined time A (for example, 90 seconds). During the predetermined time A, the mode indicator lamp 6d is in a blinking state. After the elapse of the predetermined time A (timing b), both the Peltier element 44 and the air blowing means 31 are continuously driven. When a predetermined time (for example, 1 second) elapses from the timing b, the buzzer 95 notifying the completion of preparation is driven to generate sound twice with a short “beep” sound. Both the Peltier element 44 and the blowing means 31 are driven for a predetermined time B (for example, 90 seconds). The predetermined time A is a cooling preparation time, and the cooling time of the head 2 can be shortened by driving the air blowing means 31. Further, when the predetermined time B elapses, the driving of both the Peltier element 44 and the blowing unit 31 is stopped and the blowing unit 31 is driven again (timing c).

  Here, while the predetermined time B was used for the first time and the second time, the air blowing means 31 was stopped, but during the third predetermined time B, the air blowing means 31 was continuously driven. ing. This is because of the following problems. That is, if a series of cooling operations from timings a to d are continuously repeated a plurality of predetermined times (three times in this embodiment), the heat capacity of both the thermal block 46 and the heat sink 30 can be ensured to be large. The capacity becomes insufficient, the heat storage and the heat radiation by both of them are not in time, the cooling block 45 on the low temperature surface side of the Peltier element 44 is difficult to cool, that is, the contact plate 39 is difficult to cool, and the head 2 cannot be lowered to the desired cooling temperature. There was a fear. Therefore, during the third operation, both the Peltier element 44 and the air blowing means 31 are driven even during the predetermined time B, which is the actual use time of the care, in order to enhance the heat dissipation effect. The blowing means 31 at this time may have the same driving state as the driving state for the predetermined time A, or a driving state larger than that, that is, the rotational speed of the blowing means 31 is higher than the rotational speed for the predetermined time. You may set large.

  As a result, it is possible to cause the user to recognize that the usage is incorrect (continuous use) by generating a state different from the normal use state. Even when continuously used, it is possible to promote heat dissipation and cool the head 2 by continuously driving the air blowing means 31. Timing c is when the maintenance is completed, and the buzzer 95 for notifying the completion of the maintenance is driven twice with a long sound of “Peepy”. When a predetermined time C (for example, 30 seconds) elapses after the blowing unit 31 is driven again, the driving of the blowing unit 31 is stopped (timing d). Even if the skin care is finished by the predetermined time C, the air blowing means 31 can still be driven, so that the head 2 has a desired cooling temperature when the next user performs skin care. Cheap. In the third cooling operation, the mode indicator lamp (light emission display means) 6d is in a blinking state for both predetermined times A and B to warn of continuous use. Further, after the timing c, the mode indicator lamp 6d is turned off. In this case as well, a total of 210 seconds is required from the switch-on to the end of the operation, but a series of cooling operations are automatically performed by the control circuit 87 according to the program. In addition, the operation | movement for the predetermined time C which drives only the ventilation means 31 can also be skipped. Thereafter, if the count is not reset, the fourth cooling operation is the same as the third cooling operation, and the subsequent cooling operation is the same as the third cooling operation.

  In the fourth mode (cool mode = cooling operation), when the power button 3 is pressed again and the power is turned off at the predetermined time A which is the cooling preparation time, the control circuit 87 Although the number of operations is not counted, the control circuit 87 counts the number of cooling operations when the power button 3 is pressed again and the power is turned off at predetermined times B and C after the timing b. .

  The count of the number of cooling operations in the control circuit 87 is reset when the following operation is performed. That is, the number of cooling operations in the control circuit 87 each time a series of programmed cooling operations are completed or each time the power button 3 is pressed again at a predetermined time B and C after the timing b and the power is turned off. As described above, the memory circuit is counted one by one. Thereafter, when the power button 3 or the mode button 4 is turned on, the first electrode 9 is turned on in the first mode, the second mode, or the third mode. -When the human body is detected by touching the second electrode 10 at the same time, that is, when the skin of the human body (skin) is energized, or when the power plug 74 is pulled out of the instrument and the power is turned on. When the power is turned off, that is, when the supply of power to the instrument is completely stopped, the counted number is controlled to be reset. The predetermined number of times is three in the present embodiment, but may be two, four, five, or more.

  When the mode button 4 is turned on, the first mode (cleansing mode), the second mode (vibration mode), the third mode (moisture penetration mode), and the fourth mode (cool mode = cooling operation) are automatically performed. It is possible to provide a fifth mode (full care mode) in which the transition operation is continuously performed. In this case, a considerable amount of time is required from the time when the mode button 4 which is the drive switch for the cooling operation is turned on to the fourth mode where the cooling operation is started. In this way, just the timing when the switch is turned on is performed. The cooling operation is not limited to the above, and may be started after a predetermined time (for example, 1 second or several minutes) after the switch is turned on.

  In addition to the above mode, another mode is a sixth mode (simultaneous care) in which driving of the Peltier element (thermoelectric conversion element) 44, driving of the vibrator 33, and voltage application to the first electrode 9 and the second electrode 10 are performed simultaneously. Mode) may be provided.

  The sound generation display means is not limited to a buzzer, but stores predetermined sound data in the control circuit 87, and a signal output from the sound output circuit of the control circuit 87 is sent from a separately provided speaker according to the timing of the cooling operation. It may generate sound. At the timing of the cooling operation in the above embodiment, for example, when the cooling preparation is completed, “Preparation of cooling is completed” is displayed as a preparation completion display, and “Preliminary cooling is finished immediately” is displayed as a pre-bell display before driving of the Peltier element 44 is completed. “When the driving of the Peltier element 44 is finished, the sound is driven to sound as“ Cooling is finished. ”As an end display indicating the end of the cooling use time. It should be noted that this sound-producing display means may be used alone or in combination with a buzzer.

The cooling unit 12 includes a thermoelectric conversion element 44, and a cooling block 45 and a heating block 46 that are in close contact with the low temperature side and the high temperature side with the element 44 interposed therebetween,
The heat block 30 is connected to the heat block 46.
The volume of the hot block 46 is set larger than the volume of the cold block 45,
The volume of the heat sink 30 is set larger than the volume of the thermal block 46,
A control circuit 87 for controlling the driving of the thermoelectric conversion element 44 and the air blowing means 31 is disposed inside the main body case 1.
In response to the operation of the switches 3 and 4 provided in the main body case 1, the control circuit 87 starts driving the thermoelectric conversion element 44 and the air blowing means 31, and the driving of the thermoelectric conversion element 44 is continued as it is for a predetermined time. On the other hand, the driving of the blower unit 31 is stopped, and after a predetermined time has passed, the driving of the thermoelectric conversion element 44 is controlled to stop.
As a result, the cooling preparation time of the head 2 can be shortened, and the power consumption of the entire instrument can be reduced by stopping the driving of the blowing means 31. Further, if the air blowing means 31 includes the motor 66 and the fan 67 attached to the rotating shaft, the cooling preparation time of the head 2 can be shortened and the driving is stopped during the usage time, so that the user is comfortable. You can take care of your skin. In addition, during the cooling preparation time, the sound generated by the rotation of the air blowing means 31 stops when the preparation time ends. As a result, the user can recognize the change in sound and determine whether or not it can be used, thereby improving usability.
Further, since the heat generated on the high temperature surface side of the thermoelectric conversion element 44 can be stored by the heat capacities of both the heat block 46 and the heat sink 30, the driving of the blowing means 31 can be intentionally stopped. Alternatively, if the heat capacity is small, when the motor 66 for the air blowing means 31 stops carelessly, the low temperature surface side of the thermoelectric conversion element 44 becomes hot, and accordingly the head 2 (contact plate 39) becomes hot and gives the user. There are times when it makes me feel uncomfortable, but it can be prevented.

  As a second embodiment of the present invention, the basic structure and basic operation are the same as those of the first embodiment, but the drive of the blowing means 31 is not stopped at a predetermined time B, which is the actual use time of the care. It is also possible to perform control to limit driving (see FIG. 12). That is, the number of rotations of the blowing unit 31 at the predetermined time B is made smaller than the number of rotations at the predetermined time A to reduce noise. This is done by suppressing the current from the control circuit 87 and reducing the output of the motor 66. In a case where a series of cooling operations are continuously repeated a predetermined number of times, in this embodiment, when the third cooling operation is performed, as shown in FIG. However, it is possible to enhance the cooling effect by driving in the same state as at the predetermined time A. Alternatively, when a series of cooling operations are continuously repeated a predetermined number of times, as indicated by the dotted line, the driving state of the blower means 31 in the first time (during normal use) at all times from the predetermined time A to C. Further, it is also possible to control to increase the cooling effect by driving the blower means 31 at a high rotation speed. This point can also be applied to the first embodiment.

The beauty instrument of the second example can be implemented in the following embodiment.
The main body case 1, the head 2 for cooling the skin surface, the cooling unit 12 including the thermoelectric conversion element 44 for cooling the head 2, the heat sink 30 for heat dissipation connected to the cooling unit 12, Air supply means 31 for supplying exchange air,
A control circuit 87 for controlling the driving of the thermoelectric conversion element 44 and the air blowing means 31 is disposed inside the main body case 1.
In response to the operation of the switches 3 and 4 provided in the main body case 1, the control circuit 87 starts driving the thermoelectric conversion element 44 and the air blowing means 31 and restricts the driving of the air blowing means 31 when a predetermined time elapses. When the predetermined time has elapsed, the driving of the thermoelectric conversion element 44 and the blowing means 31 is controlled to stop.
As a result, the cooling preparation time of the head 2 can be shortened and the power consumption of the entire instrument can be reduced by restricting the driving of the blowing means 31. Further, if the air blowing means 31 includes a motor 66 and a fan 67 attached to the rotating shaft thereof, the cooling preparation time of the head 2 can be shortened, and the air blowing means 31 becomes low noise during use time, and the user is comfortable. You can take care of your skin. In addition, during the cooling preparation time, if the sound generated by the driving of the air blowing means 31 is completed, the sound becomes low output driving when the preparation time ends. As a result, the user can recognize the change in sound and determine whether or not it can be used, thereby improving usability.

  FIG. 14 is a timing chart of the cool operation showing the third embodiment of the beauty tool of the present invention. Since the basic structure and the basic operation are the same as those in the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  In the third embodiment, the predetermined time B does not cause the head 2 to contact the skin, but the microcomputer timer circuit shifts to the next operation in 90 seconds of the predetermined time. The time B of 90 seconds can be the accumulated time when the human body is detected. That is, while holding the body case 1 including the second electrode 10 by hand, the cooling head 2 (first electrode 9) that also serves as a human body detection sensor is brought into contact with or separated from the skin, This is the total contact time of the head 2 with the skin when performing care. Therefore, since the time away from the skin is not actually counted, the usage time from timing b to timing c is 110 seconds exceeding 90 seconds.

  At a predetermined time A, the mode indicator 6d is in a blinking state, but after the timing b, the head 2 (first electrode 9) is held while holding the body case 1 including the second electrode 10 by hand. When touching the skin, that is, when the human body detection sensor is turned on (actuated), the mode indicator lamp 6d is turned on, and when released, the human body detection sensor is turned off and blinks.

  When the accumulated time of counting the contact time with the skin reaches a predetermined time of 90 seconds (timing c), the control circuit 87 stops driving the thermoelectric conversion element 44 and the light emitting display means 6d while driving the air blowing means 31. To do. At this timing c, the sound generation display means 95 is driven for a predetermined time to notify the user that the skin care has been completed. When the predetermined time (for example, 30 seconds) elapses, the blowing unit 31 stops driving (timing d). As described above, the first electrode 9 and the second electrode 10 are human body detection sensors for the cool mode (cooling operation), and can accurately count the contact time of the head 2 with the skin. Therefore, it is possible to prevent the head 2 from being finished with little skin care.

  When the switch is turned on and the cooling operation starts (timing a), the human body detection sensor sends a weak current (pulse signal) for human body detection with a long off time to the first electrode 9, When holding the main body case 1 with the hand and applying the first electrode 9 to the skin, the weak current (pulse signal) output from the first electrode 9 passes through the human body and the second electrode is the other electrode. 10, the human body detection signal determination circuit of the control circuit 87 is turned on, the signal is sent to the microcomputer, and the human body detection is confirmed. When the total of the fixed times reaches 90 seconds, which is a predetermined time, the control circuit 87 performs the control as described above.

  Further, when the head 2 is brought into contact with the skin while continuously moving, there is a possibility that the cooling of the head 2 is hindered by the heat from the skin and the skin does not feel cold. In addition, when the head 2 is brought into contact with the skin continuously stopped, there is a possibility that the skin may be excessively cooled. Therefore, in this embodiment, if the human body detection by the first electrode 9 and the second electrode 10 is continuously performed for a predetermined time (for example, 10 seconds) (timing b1), the sound generation display means (buzzer) 95 is Drive continuously with “pipip ...”. At this time, the vibration display means (vibrator) 33 is also driven simultaneously. As a result, the continuous contact of the head 2 with the skin can be displayed with a warning by sound and vibration. The sound generation display means (buzzer) 95 and the vibration display means (vibrator) 33 are driven while the human body is being detected. If human body detection is not performed, that is, if one electrode or both electrodes are separated from the skin, driving of the sound generation display means (buzzer) 95 and the vibration display means (vibrator) 33 is stopped (timing b2). The sound generation display means (buzzer) 95 and the vibration display means (vibrator) 33 may drive both as in the present embodiment, but can also be controlled to drive either one. In the third embodiment, the air blowing means 31 for supplying heat exchange air to the heat sink 30 is not always necessary and can be omitted.

  The human body detection sensor may have the following structure other than the above. For example, the head 2 is configured to be floatable with respect to the main body case 1. At this time, the head 2 is pushed up and biased by a spring disposed in the main body case 1. A small switch such as a micro switch or a tact switch that contacts the lower end of the head 2 when the head 2 sinks is disposed inside the main body case 1. When the head 2 is pressed against the skin surface, the head 2 sinks against the urging force of the spring, and the small switch is pressed against the lower end of the head 2 to turn on the switch. An output signal from the small switch is transmitted to the control circuit 87. As a result, the control circuit 87 determines that the contact with the skin has been confirmed. That is, using this as a human body detection sensor, the same control as the control related to the human body detection of the third embodiment can be performed.
