[ In other words, the cross sectional area of the head case 20 is set to gradually decrease from the side of the outer opening in the main body wall 22 toward the side of the mount base 24 with respect to the main body case 1. [ The head case 20 is integrated with the main body case 1 by fitting the mounting base portion 24 at the inner end of the main body wall portion 22 into the mounting seat 13 of the main body case 1. [ The outer surface of the outer wall portion 23 is an attachment portion 25 for the heat transfer member 21 and a flange (cap attachment portion) 26 protrudes from the base end portion of the attachment portion 25.

The heat conductive member 21 is fixed such that its normal peripheral wall is externally mounted on the outer surface of the outer cylindrical wall portion 23 and is not separated by the retaining ring 30 fixed to the flange 26. [ The peripheral wall of the heat conductive member 21 and the outer cylindrical wall portion 23 are fixed by the O ring 31 fitted into the outer cylindrical wall portion 23 in order to prevent the cosmetic liquid from intruding into the head case 20. [ As shown in Fig.
The electrothermal member 21 serves also as a skin electrode (electrode portion) 32. The electrothermal member 21 cooperates with the aforementioned grip electrode 11 to apply a weak pulse current to the skin surface through the human body, Gives a current stimulus for the dragon. Therefore, the heat conductor 21 is connected to the current adjusting circuit via the spring electrode 65 pressed to the inner surface of the heat conductor 21, and the grip electrode 11 has the spring electrode 66, And is connected to the current adjusting circuit.

The heater frame 34 and the heater holder 35 are both made of plastic molded article.
The heater frame 34 is provided with a heat insulating surface wall 38 formed in a disk shape, a leg piece 39 provided at two places around the face wall 38 and a leg piece 39 provided at the projecting end of the leg piece 39 And a fastening seat 40 are integrally provided. At three places on the outer surface side of the face wall 38 supporting the heater holder 35, the screw seat 41 is bulged outward. As shown in Fig. 7, the leg piece 39 is recessed inward from the peripheral edge of the disk-shaped face wall 38, and its cross-section is formed in the shape of a partial circle. The concave portion of the leg piece 39 on the partial arc is obtained by engaging the screw boss 27 formed on the inner surface of the mount base portion 24 of the head case 20 with the leg piece 39, In order to temporarily position the case 20. By forming the end surface of the leg piece 39 in the shape of a partial arc, the bending strength of the leg piece 39 can be improved and the heater holder 35 and the heater unit 36 can be firmly fixed and supported.
The heater holder 35 includes an attachment wall 44 on the disk supporting the heater unit 36 and a mounting portion 45 provided on the surface of the attachment wall 44 opposed to the heater frame 34, And a nazar boss 46 formed around the mounting portion 45 in correspondence with the screw seat 41 as a single unit. On the outer surface of the attachment wall 44, a heater recess 47 for housing the heater unit 36 is formed concavely. The mounting portion 45 is provided to receive the vibrator 50 and includes a sound insulating wall 48 surrounding the vibrator 50 and a receiving rib 49 provided on the inner surface of the sound insulating wall 48 . As described above, the vibrator 50 is disposed between the heater holder 35 and the face wall 38 for heat insulation of the heater frame 34.
The vibrator 50 is composed of a motor 51 and an eccentric weight 52 fixed to the output shaft of the motor 51. The vibrator 50 is fixed to the heater holder 35 by mounting the motor holder 53 externally impressed to the motor 51 inside the preceding soundproof wall 48. [ The vibrator 50 in a state in which the heater frame 34 and the heater holder 35 are assembled to the main body case 1 is configured such that the center axis of the motor 51 is aligned with the heat transfer surface 21a of the heat transfer body 21 And is fixed to the mounting portion 45 in a parallel state. Therefore, the main direction of the vibration oscillated in the vibrator 50 is a direction orthogonal to the heat transfer surface 21a of the heat transfer body 21. [ That is to say, when the heat transfer surface 21a of the heat transfer body 21 is vibrated in the vibrating direction of the vibrator 50 in the direction orthogonal to the heat transfer surface 21a and the cosmetic treatment is performed in the heat transfer head 21, The skin surface can be made to vibrate at the heat transfer surface 21a of the heat transfer body 21 to vibrate.
The heater unit 36 is constituted by a circular surface heater 56 and a pair of electrode plates 57 and 58 for holding the surface heater 56 between the inside and the outside. The planar heater 56 is constituted by a PTC heater. Three spring arms 59 are provided in the electrode plate 58 accommodated in the heater recess 47. The spring plates 59 are used to pressurize the surface heater 56 toward the electrode plate 57 by press- . The outer electrode plate 57 is locked by the peripheral edge of the attaching wall 44 of the heater holder 35 to keep the surface heater 56 in position, 60 in the thickness direction within the range of the claw length. The elastic sheet 37 is made of silicone rubber rich in thermal conductivity and disposed between the electrode plate 57 and the heat transfer member 21 so that the heat of the heater unit 36 is conducted to the heat transfer member 21. [ And vibrates the vibrator 50 to the heat transfer body 21.
The thermal head 2 is assembled to the front case 1a in the following manner. The heater unit 36 and the elastic sheet 37 and the vibrator 50 are assembled to the heater holder 35 and the heater frame 34 and the heater holder 35 are screwed into the screw boss 46 (Second fastening) 61 to obtain a heat generating structure in the form of a unit part. In this state, the motor holder 53 is tightly held and fixed by the heater holder 35 and the heater frame 34 (see Fig. 6). The mounting base portion 24 of the head case 20 is fitted and fixed in the mounting seat 13 from the outer surface of the front case 1a and the heat generating structure in the form of a unit component is mounted from the inner surface side of the front case 1a And is temporarily assembled in a state in which the fastening seat 40 of the heater frame 34 is joined to the inner surface of the seat seat 13a of the seat 13.
Next, the screw (third fastening) 63 inserted into the fastening seat 40 and the seat wall 13a is screwed into the screw boss 27 formed on the inner surface of the head case 20, The head case 20 and the seat wall 13a and the fastening seat 40 of the heater frame 34 are fastened together. The head case 20 fixed to the main body case 1 has a structure in which most of the main body wall portion 22 protrudes forward (outer surface) of the main body case 1, There is an incline. The O-ring 62 is held between the main body wall portion 22 of the head case 20 and the mounting seat 13 of the main body case 1 by being fitted to the outer surface of the main body wall portion 22.
The front wall 38 of the heater frame 34 is fitted to the mounting portion of the main body wall portion 22 of the head case 20 in a state in which the head case 20 and the heat generating structure are integrated with the main body case 1 Is located on the inner surface of the base 24 side, and the inside of the head case 20 is divided into inside and outside. As a result, it is possible to prevent the air heated by the heater unit 36 from flowing toward the main body case 1 as much as possible. In other words, the face wall 38 functions as a heat insulating partition wall for preventing the movement of the heated air, thereby preventing the heat movement inside the head case 20.
The heater unit 36 and the elastic sheet 37 are clamped and fixed by the heat transfer member 21 and the attachment wall 44 of the heater holder 35 in the above fastened state. The heater unit 36 in this state is accommodated in the end wall of the heat transfer member 21 via the elastic sheet 37 so that the spring arm 59 of the inner electrode plate 58 is slightly elastically deformed, And is pressed against the inner bottom of the heater recess 47. 6, the locking claws 60 of the outer electrode plate 57 are separated from the rear surface side of the peripheral edge of the attachment wall 44 of the heater holder 35, The electrode plate 57 can move toward the side of the heat transfer member 21 by a distance. The electrode plate 57 is movably supported so as to be movable outward when the heater unit 36 is heated by the heater unit 36 to thermally expand outwardly, 21 so as to carry out the heat conduction to the heat conductor 21 precisely.
As described above, when the heater unit 36 is provided inside the thermal head 2, the heat of the surface heater 56 flows, and the thermal conductive material 21 and the head case 20 are passed through the body case 1, There is a possibility of moving to the side. However, if the main body wall portion 22 is formed as a bell mouth with a constricted portion, the cross sectional area of the head case 20 is set so as to extend from the outer opening side of the outer cylinder wall portion 23 to the side of the mount base portion 24 The amount of heat conducted to the main body case 1 side can be reduced. Therefore, the heat conductive member 21 can be efficiently heated by the surface heater 56. [
(Structure of cold part)
1 and 8, the cold heat unit 3 includes a square Peltier element (thermoelectric conversion element) 70, a cold head 71 disposed on the outer surface (one side) of the Peltier element 70 for outputting cold heat, And a heat sink 72 disposed on the inner surface (other surface) of the Peltier element 70 to emit heat. The Peltier element 70 is supported by the element holder 73, and the heat transfer sheet 74 is attached to each of the heat-radiating surface and the heat-radiating surface. The element holder 73 is made of a plastic molded article integrally provided with a disk-shaped holding wall 75 and a fastening arm 76 connected to and projected from two peripheral portions of the holding wall 75, A holding hole 77 having a rectangular shape for receiving the Peltier element 70 is formed at the center. A boss 78 for inserting the screw is formed on the surface of the holding wall 75 on the heat sink side. The heat transfer sheet 74 is made of silicone rubber in the same manner as the elastic sheet 37 described above.
The cooling / heating head 71 has a quadrangular-shaped heat-collecting portion 82 protruding from the heat storage portion 81 on the disk block and facing the Peltier element 70 of the heat-storage portion 81, A screw boss 83 protruding from two places around it, and a flange 84. The die-cast molding is made of aluminum. The cooling / heating head 71 is fixed to the rear case 1b by fitting the heat storage portion 81 to the mounting window 14 of the rear case 1b from the inner side of the case, The outer heat transfer surface 81a is exposed on the outer surface of the mounting window 14 (see FIG. 1). The heat sink 72 is formed in a long axis, and is arranged inside the body case 1 which is elongated vertically along the case axis.
The heat sink 72 includes a sink base 88 on the wall surface and a group of front fins 89 protruding from the front surface of the sink base 88 and a pair of front fins And a rear fin (heat dissipation protrusion) 90 protruding from the base plate 90 (heat dissipating protrusion). 8, the sink base 88 includes a normal upper base 91 provided above the base, and a lower base 92 connected to the lower side wall of the upper base 91 and vertically connected and projected And a quadrangular heat receiver 93 is formed on the rear face side of the vertical wall of the upper base 91 so as to protrude therefrom. A screw insertion hole 96 is formed on the left and right sides of the upper base 91 (see FIG. 1). The heat dissipating protrusions 89 and 90 need not necessarily be of a finned structure on the wall, but may be formed as a round film object or an angled film object.
11, an annular wall 94 on a square frame is provided on the rear surface of the lower base 92 to form a quadrangular heat dissipating partition 95. As shown in Fig. The front pin 89 protrudes forward from the lower surface of the upper side wall of the upper base 91 to the lower end of the lower base 92. The rear pin 90 is formed so as to protrude toward the lower end of the upper base 91 And is formed so as to protrude rearward from the lower surface of the lower side wall to the lower end side of the lower base 92. The protruding end edge of the rear fin 90 is curved along the curved shape of the rear case 1b and the protruding end of the annular wall 94 and the inner surface of the rear case 1b opposed to the copper wall 94 , And the seal grooves 113 and 114 on the square frame are concave (see Figs. 8 and 11), respectively.
As described above, the front pin 89 and the rear pin 90 are elongated vertically along the vertical case shaft of the body case 1, which is elongated vertically. Specifically, as shown in Fig. 12, the vertical length H2 of the heat sink 72 is set to be at least half the length of the vertical length H1 of the main body case 1, The generated heat can be reliably dissipated by the heat sink 72 having a large surface area. The volume of the sink base 88 is set to be sufficiently larger than the volume of the cooling head 71 so that the heat transfer amount (heat capacity) per unit time of the heat sink 72 is increased. Therefore, when the cold / hot part 3 is used, the heat generated by the Peltier element 70 can be effectively conducted to the side of the heat sink 72, and the heat can be properly dissipated.
The cold / hot part 3 is assembled to the rear case 1b in the following manner. First, the Peltier element 70 is assembled to the holding hole 77 of the element holder 73, and the heat transfer sheet 74 is attached to the front and rear surfaces thereof. A heat sink 72 is attached to the front side of the element holder 73 in this state and a cooling head 71 is attached to the rear side of the element holder 73. Two pieces of the heat sink 72 are inserted into the screw insertion hole 96 and the boss 78 The screw (fourth fastening) 97 is twisted to the screw boss 83 (see Fig. 1) to obtain a cooling / heating structure in unit parts. Next, a rectangular shaped packing 102 is mounted on the portion of the rear case 1b facing the annular wall 94, and the heat storage portion 81 of the cooling head 71 is fitted into the mounting window 14, And the whole of the cooling / heating structure is positioned with respect to the rear case 1b.
The right and left fastening arms 76 of the element holder 73 and the screw (fifth fastening) 99 inserted into the screw insertion through hole 98 formed at the center of the bottom of the heat sink 72, The heat and cooling structure twisted in the screw boss 100 (see Figs. 4 and 11) formed in the case 1b is fixed to the rear case 1b. The gap between the heat accumulating portion 81 and the mounting window 14 is sealed by the O-ring 101. The front case 1a in which the rear case 1b in this state is assembled with the front case 1a in which the heating head 2 and the control board 17 are assembled is joined in a cover fit fit manner and the both cases 1a, A beauty device having the thermal head 2 and the cold / warm section 3 is obtained.
The left and right sides of the upper portion of the heat sink 72 and the lower portion of the upper portion of the heat sink 72 are fastened and fixed to the main body case 1 by the fifth fasteners 99. When the heat of the heat sink 72 is removed from the cooling head 71 It is possible to conduct heat to the main body case 1 at a remote position and dissipate heat. This is because the left and right sides of the upper portion of the heat sink 72 are fastened and fixed to the main body case 1 via the holder 73 so that the heat conduction to the main body case 1 is small, Because it is small. Since the lower side of the heat sink 72 is fastened to the main body case 1 with the fastening hole 99, heat can be conducted and dissipated at a position distant from the cooling / heating head 71, 71 can be effectively suppressed while suppressing the influence of heat.
As described above, in the state where the cooling / heating structure is assembled to the main body case 1, the rear fins 90 provided at the lower half of the heat sink 72 are spaced apart from the inner wall of the rear case 1b by a gap E (See Fig. 8). The protruding end of the annular wall 94 is in close contact with the packing 102 to form an annular heat dissipating partition 95 between the rear case 1b and the lower base 92. [ A plurality of heat dissipating openings 103 are formed in the case wall of the rear case 1b facing the heat dissipating partition 95 so as to promote heat exchange in the heat dissipating space 95, It can be effectively discharged to the outside of the case 1. Since the metal grip electrode 11 disposed below the heat dissipation port 103 functions as the heat dissipation plate 104, the heat of the heat sink 72 conducted to the rear case 1b is transmitted through the heat dissipation plate 104 Can be effectively released.
Specifically, since the heat sink 104 is provided on the outer surface of the rear case 1b facing the lower portion of the heat sink 72, the heat of the heat sink 72 can be effectively dissipated. Further, since the heat sink 104 is disposed up to the position where it protrudes downward from the lower end of the heat sink 72, the heat radiation area can be increased to further improve the heat radiation effect. In addition, since the heat sink 104 is disposed at the position facing the screw 99 for fastening the lower end of the heat sink 72 to the front, heat of the heat sink 72 can be more effectively dissipated.
9, a rear fin (radiating fin) 90 and a concave portion 105 are alternately formed on a lower base 92 that faces the heat dissipating partition 95. As shown in Fig. The gap E between the rear fin 90 and the rear case 1b is set to be smaller than the case thickness of the rear case 1b. In this way, the clearance E is formed and the clearance E is set to be smaller than the case thickness of the rear case 1b in the case where the rear fin 90 is in close contact with the rear case 1b, The temperature of the contact portion with the rear fin 90 tends to be higher than other portions. When the value of the gap E is larger than necessary, the heat radiated from the rear fins 90 tends to fill the inside of the case without being discharged to the outside of the case through the rear case 1b It is because. In other words, the clearance E is set to be greater than the case thickness of the rear case 1b in order to efficiently transfer the heat of the heat sink 72 to the main body case 1 while avoiding the locally high temperature of the main body case 1. [ . Further, the thickness of the rear case 1b in this embodiment is 2.0 mm, and the value of the gap E is 1.0 to 1.8 mm.
12, the control circuit includes a heater unit 36, a vibrator 50, a device control circuit 106 for controlling the operating state of the Peltier device 70, And a skin current control circuit 107 that adjusts one pulse current and outputs a pulse current to the grip electrode 11 and the skin electrode 32. [ Hereinafter, the operation mode of the beauty device and the control of each device in each operation mode will be described in detail. The lighting state of the mode indicator 8 or the intensity indicator 9 is controlled by the device control circuit 106. [
After the power button unit 5 is turned on, the beauty device is switched to the first to fourth operation modes each time the mode button unit 6 is depressed. And is controlled by the control circuit 106 (see Fig. 12). If necessary, a weak pulse current adjusted by the skin current control circuit 107 is outputted to the grip electrode 11 and the skin electrode 32, or the polarity thereof is switched. When the cosmetic device is used, a face mat (sheet-like liquid) 110 impregnated with a lotion is placed on the outer surface of the skin electrode 32, Is used in a state in which it is fixed by a cap (111) which is pressed and inserted into the cap (26). As shown in Fig. 3, the cap 111 is formed of a ring-shaped plastic molded article having front and rear faces open. Four positions of the inner surface of the ring wall on the base end side are engaged with the flange 26 to form a resiliently deformable engaging claw 112 Are integrally formed.
(First operation mode)
In the first operation mode, the face mat 110 impregnated with the lotion is mounted on the skin electrode 32 to perform ion extraction processing for dropping fine contamination that has entered the wrinkles and pores of the face skin. More specifically, as shown in Fig. 13, when the power button unit 5 is turned on, the uppermost color mode indicator 8 is lit, and the intensity indicator lamp 9 at the left end is turned on at the same time The sounding body, which is not shown in the figure, sounds "beep". In addition, a weak pulse current for skin detection with a long off-time is supplied to the grip electrode 11 and the skin electrode 32 by waiting for a predetermined time t1 to elapse after the power button unit 5 is turned on do. In a state in which the main body case 1 and the grip electrode 11 are held by one hand and the skin electrode 32 is brought into contact with the face skin, the aforementioned pulse current passes through the human body. This state is the skin detection state. The heater unit 36 waits until the predetermined time t2 (5 seconds) elapses after the power button unit 5 is turned on and the operation mode is switched in parallel with the supply of the pulse current for skin detection, ) Is started. The time t1 until the power button section 5 is turned on and the operation mode is switched is an arbitrary time because there is an individual difference according to the user of the beauty apparatus.
In a state where the skin electrode 32 contacts the face skin and the skin electrode 32 and the grip electrode 11 are electrically connected after the power button unit 5 is turned on, The positive polarity pulse current is supplied and the vibrator 50 is activated. The predetermined time t3 is an arbitrary time until the skin detection state is recognized, and is the time until the user touches the skin electrode 32 with the face skin. The user can press the face mat 110 attached to the skin electrode 32 (heat conductor 21) against the face skin or slide the face mat 110 along the skin face in a pressed state, Can be captured. In the meantime, when the current stimulus to the skin surface is small, the switch button section 7 for switching the intensity of the current stimulus can be operated to adjust the stimulus intensity to the preference. Supply of the driving current to the heater unit 36 and the vibrator 50 is stopped at the same time and the supply of the driving current to the heater unit 36 and the vibrator 50 is stopped at the same time, The indicator light 8 and the intensity indicator lamp 9 are turned off. At this time, the sound emitting object sounds "beep", and the first operation mode is ended. Incidentally, when no signal for skin detection is obtained even after 3 minutes have elapsed since the power button section 5 was turned on, the power is turned off and returned to the standby state.
(Second operation mode)
In the second operation mode, the cotton mat 110 impregnated with the lotion is basically mounted on the outer surface of the skin electrode 32 (the heat transfer member 21) in the same manner as in the first operation mode, Increase the moisturizing effect by penetrating the skin lotion with lotion. Also in the second operation mode, the pulse current of the positive polarity is supplied to the skin electrode 32 at the time when the skin detection state is attained as in the first operation mode, and at the same time, the vibrator 50 is activated. However, in the second operation mode, the pulse electric current of negative polarity is supplied to the skin electrode 32 to accelerate the infiltration of the lotion. In the first operation mode, the pulse electric current of the positive polarity is supplied to the skin electrode 32, Is different from the first operation mode. In the second operation mode, the mode light 8 of the second color from the top turns on. Supply of the driving current to the heater unit 36 and the vibrator 50 is stopped at the same time when the pulse current is supplied to the skin electrode 32 for three minutes after the pulse current of minus polarity is supplied. At the same time, the mode indicator 8 and the intensity indicator 9 are turned off, and the sounding object notifies that the second operation mode has ended.
In the second operation mode, cosmetic liquid such as gel-like lotion with high viscosity, or cosmetic solution such as milky liquid is applied to the warm head 2 without using the facial mat 110 impregnated with the lotion, And can be used in a straightened state. In this case, since the cosmetic solution can be held by the liquid holding part 29 formed concavely in the heat transfer surface 21a, the cosmetic treatment can be carried out without problems even though the surface mat 110 is not used . The user can infiltrate the cosmetic solution into a wide range of facial skin by pressing the skin electrode 32 against the facial skin or sliding it along the skin surface in a compressed state. Since the liquid retaining portion 29 is formed in a circular shape, when the skin surface is treated using the skin electrode 32, the liquid retaining effect of the liquid retaining portion 29 prevents the skin surface The applied cosmetic solution can be spread widely by moving it in all directions. Since the liquid holding portion 29 is formed in a circular shape so as to surround the periphery of the heater unit 36, the concave portion of the liquid holding portion 29 and the heater unit 36 are prevented from interfering with each other, The front and rear dimensions of the thermal head 2 can be reduced.
(Third operation mode)
In the third operation mode, the third color mode light 8 is lit from the top, and a pulse current is supplied to the facial skin to operate the heater unit 36. As in the first operation mode, When the detection state is reached, a pulse current of a positive polarity is supplied to the skin electrode 32, and the skin surface is trimmed by cosmetic treatment in a state in which the vibrator 50 is activated. However, in the third operation mode, the skin electrode 32 (heat conductor 21) is subjected to a cosmetic treatment in a state in which a pulse current of a positive polarity and a pulse current of a negative polarity are alternately applied. In the third operation mode, the facial skin is covered with a sheet mask, or the facial skin is applied to the facial skin without using the face mat 110 impregnated with the lotion. The supply of the driving current to the heater unit 36 and the vibrator 50 is stopped at the same time when the supply of the pulse current is stopped and the supply of the driving current to the heater unit 36 and the vibrator 50 is stopped at the same time when three minutes have elapsed after the pulse current is supplied to the skin electrode 32 in the third operation mode. do. At the same time, the mode indicator 8 and the intensity indicator 9 are turned off, and the third operation mode is terminated in the sound emitting object.
(Fourth operation mode)
In the fourth operation mode, the lowermost blue mode display lamp 8 is turned on, and the cooling head 71 is cooled by the Peltier element 70 to perform a cosmetic treatment. When the operation mode is switched to the fourth operation mode by operating the mode button unit 6 after the power button unit 5 is turned on, a driving current is supplied to the Peltier element 70, Cooling is started. The cooling head 71 is rapidly cooled by continuously supplying a current of 2.7 V to the Peltier element 70 until the primary cooling time T1 (40 seconds) elapses from the start of cooling of the cooling / heating head 71.
However, if the Peltier element 70 is driven continuously with the above voltage, the cooling head 71 is excessively cooled and the heat on the side of the heat sink 72 is fed back to the cooling head 71, Can not be cooled to a predetermined temperature state. In order to solve this problem, the voltage V1 from the start of cooling of the cooling head 71 to the elapse of the primary cooling time T1 (40 seconds) is set to 2.7 V, and the primary cooling time (40 seconds) At this time point, the drive current supplied to the Peltier element 70 is pulsed, and the pulse current is supplied to the Peltier element 70. The applied voltage V2 at this time is limited from 2.7 V to 2 V during the primary cooling. Thereafter, the Peltier element 70 is driven with a pulse current of 2.0 V until the secondary cooling time (80 seconds) elapses.
The user can start using the hairdressing device at the time when the first cooling time T1 has elapsed from the start of cooling of the cooling head 71 and can use the hairdressing device until the second cooling time T2 elapses. In the fourth operation mode, the heat transfer surface 81a of the cooling head 71 is placed on or away from the face skin in the same manner as in the case of padding the face skin using the cosmetic puff, To the outer periphery. In the fourth operation mode, supply of the driving current is stopped when two minutes have elapsed from the supply of the current to the Peltier element 70. [ At the same time, the mode indicator 8 and the intensity indicator 9 are turned off, and it is noticed that the fourth operation mode is ended in the sound emitting object.
While the control circuit has been described as an example of control for each operation mode by the control circuit, the control circuit stores the operation mode used last time each operation mode is ended. When the power button section 5 is turned on next time , The next operation mode of the previously used operation mode is set to the start operation mode and the control is executed. In the case where the fourth operation mode is repeatedly selected, the primary cooling time T1 for cooling the cooling head 71 is gradually changed to eliminate the feedback effect of the heat on the side of the heat sink 72, So that it can be reliably cooled to a predetermined cold temperature.
Specifically, for example, when the room temperature is 25 占 폚, the drive current of 2.7 V is applied to the Peltier element 70 in the first operation mode, and the primary cooling time T1 (40 seconds) And the cooling head 71 at 25 占 폚 is lowered to 15 占 폚. Subsequently, the Peltier element 70 is driven with a pulse current of 2 V until the secondary cooling time T2 elapses. Therefore, the heat sink 72 at the time of the completion of the first fourth operation mode is in a state of being heated up to about 35 占 폚, and after the end of the first fourth operation mode, When the operation mode is selected, the heat of the heat sink 72 is fed back to the Peltier element 70. Therefore, even if the Peltier element 70 is driven under the same conditions as the first operation mode for the first time (primary cooling time T1 = 40 seconds) for the second time, the temperature of the cooling head 71 can not be lowered to 15 DEG C do.
In order to cope with the feedback action of the heat by the heat sink 72, as shown in Fig. 14, the first cooling time T1 is set to 60 seconds as the first time, 40 seconds as the first time, and 120 seconds as the third time It is gradually increasing. Even in such a case, the sum of the primary cooling time T1 and the secondary cooling time T2 is always constant (120 seconds), and the secondary cooling time T2 decreases as the primary cooling time T1 increases.
As described above, the fourth operation mode can be repeatedly used up to three times, but the fourth operation mode can not be used. This is because even if the amount of heat stored in the heat sink 72 exceeds the limit and the Peltier element 70 is driven for example by repeatedly using the cooling head 71 three times, And the cooling head 71 can not be cooled down to a predetermined temperature. When the fourth operation mode is selected for the fourth time, all the indicator lights (8 · 9) flicker, and the sounding object is "beep, beep" to warn the sound.
The change of the first cooling time T1 in the second and third times of the fourth operation mode and the use limitation of the fourth time of the fourth operation mode are the same as those of the fourth time 60 minutes or less. This is because when the elapsed time exceeds 60 minutes, the heat of the heat sink 72 is dissipated to the room temperature.
The control of the Peltier element 70 described above can be carried out in the following manner.
A cooling and cosmetic device comprising a cooling / heating head (71), a thermoelectric conversion element (70), a heat sink (72), and a control circuit for controlling a driving current supplied to the thermoelectric conversion element
The control circuit controls the drive current to be supplied to the thermoelectric conversion element 70 to be different between the elapse of the primary cooling time T1 from the start of driving and the elapse of the secondary cooling time T2,
During the elapse of the first cooling time T1 from the start of the driving of the thermoelectric conversion element 70, the control circuit continuously supplies the driving current of the predetermined voltage V1 to the thermoelectric conversion element 70,
Wherein the control circuit in the secondary cooling time T2 supplies the driving current in a state of making a pulse current and in a state in which the voltage of the driving current is set to a voltage V2 lower than the predetermined voltage V1.
When the drive current is supplied again to the thermoelectric conversion element 70 to cool the cool head 71 after the first thermoelectric conversion element 70 has been driven,
The primary cooling time T1 for driving the thermoelectric conversion element 70 in the subsequent cycle is set to be longer than the primary cooling time T1 for the previous time when the thermoelectric conversion element 70 is driven.
When the drive current is supplied again to the thermoelectric conversion element 70 to cool the cool head 71 after the first thermoelectric conversion element 70 has been driven,
The secondary cooling time T2 when the thermoelectric conversion element 70 is driven next time is set shorter than the secondary cooling time T2 when the thermoelectric conversion element 70 is driven last time.
As described above, until the primary cooling time T1 elapses from the start of cooling of the cooling head 71, a current of 2.7 V is supplied to the Peltier element 70 to cool the cooling head 71 rapidly. In order to prevent the feedback of the heat of the heat sink 72 due to the excessive cooling of the cooling head 71 during the second cooling time T2, the driving current supplied to the Peltier element 70 is pulsed , And the applied voltage V2 is further limited to 2.0 V, but the rationale thereof is as follows.
In order to prevent the cooling head 71 from being excessively cooled, as shown in Fig. 15A, the voltage V1 (2.7 V) of the driving current supplied to the Peltier element 70 at the secondary cooling time T2 is maintained at , The driving current may be changed into a pulse current. 15 (b), even when the voltage V2 (2.0 V) of the drive current supplied to the Peltier element 70 is lowered in the second cooling time T2, the cooling head 71 is excessively cooled To some extent. In either case, there is an advantage that power consumption by the Peltier element 70 can be reduced.
However, when the driving current is simply made into a pulse current, the heat of the heat sink 72 is conducted to the cooling head 71 while the pulse current is turned off, so that the cooling head 71 is hardly cooled . If the pulse width of the pulse current is made smaller, the off time is shortened, so that it is possible to solve the problem that the cooling head 71 is not easily cooled. However, in that case, since the specification of the control computer chip installed in the device control circuit 106 is over, it is necessary to use a more expensive control computer chip.
In the case of simply lowering the voltage V2 of the driving current, it is possible to prevent the cooling head 71 from being excessively cooled to some extent but not enough. For example, when the Peltier element 70 is repeatedly driven , The cooling / heating head 71 is excessively cooled more than necessary. If the voltage V2 of the driving current is further lowered, the cooling head 71 can be prevented from being excessively cooled. In this case, however, it is inevitable that the circuit component such as the diode generates heat due to the heat generating action of the resistor for lowering the voltage. For this reason, in the present embodiment, the voltage V2 of the driving current supplied to the Peltier element 70 at the secondary cooling time T2 is lower than the voltage V1 of the driving current at the primary cooling time T1, So that the Peltier element 70 is driven.
