JP 2004-141439 A (paragraph number 0027, FIG. 1) JP 2004-141438 A (paragraph number 0031, FIG. 2)

  In this type of hair treatment apparatus, a positive temperature coefficient thermistor (hereinafter referred to as a PTC heater) that can self-control the heating temperature to a constant temperature is often used as a heating element of the heating block. As long as the condition of the hair to be treated is always constant, the surface temperature of the heating block may be maintained at a constant temperature (around 140 degrees). However, there are individual differences in the physical and biochemical characteristics of hair. Furthermore, the hair condition immediately after the hair dyeing treatment or straight perm treatment is severely damaged by the cuticle on the hair surface, and the hair treatment device is used several days after this kind of hair treatment. Even in such a case, the cuticle may be destroyed by performing the hair treatment with the heating block heated to a constant temperature.

  The present inventor has prototyped a hair treatment apparatus that can set the surface temperature of the heating block to be lower than a predetermined temperature in order to cope with individual differences in hair characteristics as described above or from the viewpoint of cuticle protection. Specifically, a temperature control circuit including a volume (variable resistor) for controlling the heat generation temperature of the PTC heater is added, and the user himself operates the adjustment knob to keep the surface temperature of the heating block below a certain temperature. It can be set to any temperature. When the prototype hair treatment device was tested for use, it was found that the temperature set with the adjustment knob was not stable and varied within a certain range. As a result of identifying the cause and investigating measures for eliminating the variation in temperature, the present invention has been proposed.

  The object of the present invention is to provide a temperature control circuit for controlling the heat generation temperature of the heating element, and by adjusting the adjustment knob of the temperature control circuit, the surface temperature of the heating block can be set to an arbitrary temperature lower than a certain temperature. Accordingly, it is an object of the present invention to provide a hair processing apparatus that can perform hair processing that suits individual differences in hair characteristics, or that can reliably protect cuticles.

  An object of the present invention is to provide a hair treatment apparatus having a variable resistor for controlling the heat generation temperature of a heating element, to maintain a heating block at a stable temperature state, and to carry out hair treatment without damaging the cuticle. An object of the present invention is to provide an effective hair treatment apparatus.

  As shown in FIG. 1, the hair treatment apparatus of the present invention includes first and second pinching arms 1 and 2 that are connected via a swing shaft 3 so as to be swingable and openable. In the case 8 of the first pinch arm 1, the heat generation temperature of the blower fan 41, the motor 40, the ion generator 48, the flat heating block 5 that heats the hair, and the heating element 36 of the heating block 5 is adjusted. The variable resistor 56 which comprises the temperature control circuit 11 is arrange | positioned in the ventilation path R between the air blower outlet 19 and the ventilation fan 41 which accommodated the temperature control circuit 11 and opened in case 8. To do.

The case 8 includes a grip part A1 and a processing part A2 adjacent to the grip part A1. A variable resistor 56 is disposed in the processing part A2 of the case 8 and is variable on the outer surface of the processing part A2 of the case 8. the resistance value of the resistor 56 to place the adjustment knob 25 for adjusting operation.

Wind fan 41 feeding into the processing unit A2 of the case 8 is arranged, a variable resistor 56 is disposed adjacent to the downstream side of the blower fan 41. A variable resistor 56 is arranged at a position overlapping the heating block 5 in the length direction of the first sandwiching arm 1.

  The power supply circuit 63 for the motor 40 includes a dropper resistor 64, and the dropper resistor 64 can be disposed in the ventilation path R between the air inlet 18 and the air outlet 19 of the blower fan 41. The dropper resistor 64 can be disposed in the ventilation path R between the blower fan 41 and the air inlet 18.

  In the present invention, the temperature control circuit 11 including the variable resistor 56 is added to the hair treatment apparatus having the pair of sandwiching arms 1 and 2, and the adjustment block 25 of the variable resistor 56 is adjusted to operate the heating block 5.・ Since the surface temperature of 6 can be set to an arbitrary temperature lower than a certain temperature, it is possible to perform hair processing corresponding to different hair characteristics by an individual, or to eliminate cuticle damage due to overheating of the hair.

  Further, a variable resistor 56 constituting the temperature control circuit 11 is arranged in the ventilation path R between the air outlet 19 opened to the case 8 of the first sandwiching arm 1 and the blower fan 41, and the variable resistor 56. Is constantly exposed to the air flow supplied from the blower fan 41, the temperature of the surface and the inside of the variable resistor 56 can be maintained at a substantially constant temperature regardless of the temperature change in the case 8. . This is because the variable resistor 56 maintains a temperature state determined by its own resistance heat and the temperature of the air flow. Therefore, the resistance value does not change with the change of the temperature coefficient of the variable resistor 56, the heat generation temperature of the heating blocks 5 and 6 is stabilized, and the hair treatment can be effectively performed without damaging the cuticle.

  When the variable resistor 56 is arranged in the processing part A2 of the case 8 and the adjustment knob 25 for adjusting the resistance value of the variable resistor 56 is arranged on the outer surface of the case 8, the hair is held by gripping the grip part A1. For example, when the hair is swept away, the adjustment knob 25 is not accidentally touched, and the adjustment knob 25 does not come into contact with the head or the hair mass when the hair is sandwiched between the two sandwiching arms 1 and 2. Therefore, unless there is a clear intention of the user, the adjustment knob 25 can be prevented from being adjusted and the temperature of the heating blocks 5 and 6 can be maintained at the set temperature. Since the adjustment knob 25 can be rotated with the other hand while holding the grip portion A1 with one hand, there is an advantage that the adjustment operation of the adjustment knob 25 can be performed easily and reliably.

  When the variable resistor 56 is arranged adjacent to the leeward side of the blower fan 41, the variable resistor 56 can be wrapped with a strong air flow, so that the temperature state can be maintained in a more stable state. The heat generation temperature of the heating blocks 5 and 6 can be stabilized.

  When the dropper resistor 64 constituting the power supply circuit 63 is disposed in the ventilation path R between the air inlet 18 and the air outlet 19 of the blower fan 41, the blower fan 41 is caused by the resistance heat of the dropper resistor 64 itself. Since the air flow fed from the air can be heated, the air flow heated to a constant temperature can be fed to the heating blocks 5 and 6. In this way, when air heated by the dropper resistor 64 is fed to the heating block 5, 6, it is inevitable when normal temperature air that is not heated by the dropper resistor 64 is fed to the heating block 5, 6. It is possible to prevent the temperature rise of the surfaces of the heating blocks 5 and 6 from being hindered. Therefore, it is possible to prevent the surface temperature of the heating blocks 5 and 6 from varying depending on the ambient temperature conditions. In addition, since the dropper resistor 64 can be forcibly cooled, the temperature state can be maintained in a stable state and the resistance value can be prevented from fluctuating.

  When the dropper resistor 64 is disposed in the ventilation path R between the blower fan 41 and the air inlet 18, the air heated by the dropper resistor 64 and the air that has not touched the dropper resistor 64 cause the blower fan 41 to flow. Since it is agitated while passing, it is possible to make the temperature of the air flow blown out from the air outlet 19 uniform and to blow the air flow without temperature unevenness on the heating blocks 5 and 6.

This means that a larger amount of pressurized air can be supplied without increasing the driving speed of the blower fan 41, and further, fan noise can be reduced by the lower driving speed. The overhanging portion 24 catches the hair sandwiched between the sandwiching arms 1 and 2 from moving toward the air suction port 18 to prevent the hair from being sucked in from the air suction port 18 and pinches the hair. In this state, the first and second sandwiching arms 1 and 2 are also useful in restricting the lateral movement of the first and second sandwiching arms 1 and 2.

The adjustment knob 25 is formed in a round button shape, and an operation shaft 25a for operating the variable resistor 56 projects from the lower surface side thereof.

  The second pinching arm 2 includes a battledore-like case 30 formed in the same outline shape as the first pinching arm 1, and a heating block 6 fixed to the upper surface of the case 30 corresponding to the heating block 5 of the pinching arm 1. It consists of The case 30 includes a shallow dish-shaped lower case 30b whose upper surface is open, and an upper case 30a that closes the upper surface of the lower case 30b. Each of the upper and lower cases 30a and 30b is a plastic molded product. A group of combing teeth 34 for hairdressing is provided in a straight line along the long side portion of the heating block 6 on both the left and right sides of the upper case 30 a facing the heating block 6.

  3 and 5, the left and right intervals of the comb teeth rows of the comb teeth 34 are set to be smaller than the left and right intervals of the comb teeth rows of the comb teeth 21 provided on the first sandwiching arm 1. The inner and outer comb teeth 21 and 34 have the same front-rear position at the same front-rear pitch as shown in FIG. 3 in a state where both the sandwiching arms 1 and 2 are joined, that is, in a state where the heating blocks 5 and 6 are joined together. It is arranged as follows. The meaning will be described later.

  The processing part A2 side of the upper case 30a and the lower case 30b bulges to the lower surface side along the lower surface shape of the lower case 8b of the first clip arm 1. An opening for exposing the heating block 6 to the outside of the case is formed on the upper surface of the upper case 30a, and a recess 31 for receiving the overhanging portion 24 is formed in a recess adjacent to the opening (see FIG. 2). ). Furthermore, a round shaft-shaped restricting pin 32 is provided adjacent to the recess 31.

  The restriction pin 32 can be engaged with a screw hole 33 formed in a recess in the lower case 8b of the first sandwiching arm 1, and both these 32 and 33 are engaged before the protruding portion 24 and the recessed portion 31, The space between the first sandwiching arm 1 and the second sandwiching arm 2 is divided into the heating block 5 and 6 side and the grip part A1 side, and the hair sandwiched between the heating blocks 5 and 6 is on the side of the air suction port 18. It is possible to prevent the hair from moving into the air suction port 18 by restricting the slippage. In addition, when the hair is pinched, the heating blocks 5 and 6 can always face each other by restricting the movement of the first and second pinching arms 1 and 2 in the left-right direction. Can be done effectively.

  In FIG. 1, the heating block 5 is fastened and fixed to the electrical equipment holder 45 and a square frame-like case portion 35 that is long before and after being partitioned on the lower surface of the electrical equipment holder 45, which will be described later. The outer case 37 made of a metal plate for sandwiching and fixing the heating element 36 in cooperation with the case portion 35, and the insulating sheet disposed between the heating element 36 and the outer case 37 are included. The heating block 6 on the second sandwiching arm 2 side is configured in the same manner, except that the case portion 35 that houses the heating element 36 is an independent part and is formed in a square box shape (see FIG. 5).

  The heating element 36 is composed of a flat block PTC heater, and is fixedly held by a holder provided in the case so as not to float. The outer case 37 sandwiches the hair between its flat surfaces, and heats the hair with heat conducted from the heating element 36. In addition, the upper and lower heating blocks 5 and 6 are used by being attached to the respective sandwiching arms 1 and 2 while being turned upside down.

  4 and 6, the fan unit 9 includes a motor 40 and an axial-flow type blower fan 41 fixed to the output shaft of the motor 40. The fan unit 9 can be positioned and mounted on the upper case 8a by inserting and loading the motor 40 into a rib provided on the inner surface of the upper case 8a.

  In the ion generator 10, all the constituent parts are collected as one unit part. Specifically, a discharge current adjusting circuit 46, a transformer 47 assembled to the electrical holder 45, a pair of left and right ion generators 48, and the like are incorporated into an electrical holder 45 made of a plastic molded product to form unit parts. Boss 49 for assembling the ion generating part 48 is integrally provided on both the left and right sides of the electrical equipment holder 45 (see FIG. 5).

  In FIG. 7, a discharge current adjusting circuit 46 includes a rectifier circuit 46a for half-wave rectification of a commercial power supply (100V), a pulse generation circuit 46b for converting the rectified current into a pulse current, and a transformer 47 for boosting the pulse current. The circuit components other than the transformer 47 are mounted on the board. This substrate is cast in a plastic block together with the booster coil of the transformer 47 (see FIG. 1). The pulse current output from the pulse generation circuit 46 b is boosted to, for example, 4 kV by the transformer 47 and then supplied to the ion generation unit 48. In FIG. 7, the ion generator 48 includes a needle-shaped center electrode 51 fixed to the center of the boss 49 of the electrical equipment holder 45, a cylindrical peripheral electrode 52 fixed to the outer peripheral surface of the boss 49, It consists of an insulating cylinder 53 fixed to the peripheral surface.

  Oxygen molecules and water molecules floating in the air around the electrodes 51 and 52 are negatively ionized by the discharge action between the center electrode 51 and the peripheral electrode 52 and are ionized together with the air flow supplied from the blower fan 41. It discharges from the blower outlet 20. Since the ion blower outlet 20 and the air blower outlet 19 adjacent to the ion blower outlet 20 communicate with each other inside the case, some of the negative ions are blown out also from the air blower outlet 19.

  Minus ions containing moisture neutralize positively charged hair and prevent hair from becoming crusty. In addition, moisture penetrates deep into the hair. Therefore, the moisture content of the hair before being heated by the heating blocks 5 and 6 can be increased, and the hair can be effectively stretched. When passing through the heating blocks 5 and 6, part of the moisture that has penetrated into the hair is evaporated, but the hair that has passed through the heating blocks 5 and 6 can be re-exposed to the negative ions containing moisture to regain moisture. .

  Although the surface temperature of the heating blocks 5 and 6 is set to 140 degrees, a temperature control circuit 11 is provided according to the condition of the hair or to protect the cuticle, and the temperature is set to an arbitrary temperature (70 degrees or less) (70 ˜140 ° C.).

  The temperature control circuit 11 is applied to a negative characteristic thermistor (NTC) 55 that is disposed in close contact with the heating element 36 and detects the heating temperature, a variable resistor 56, an IC chip 57 for temperature control, and the heating element 36. The heating temperature of the heating element 36 can be changed by adjusting and changing the resistance value of the variable resistor 56 with the adjusting knob 25. Among each circuit component, the variable resistor 56 and the two adjustment resistors 59 are mounted on the substrate 60 and fastened and fixed to the inner surface of the upper case 8a inside the adjustment knob 25. Other circuit components are different from each other. It is mounted on the substrate 61 and fastened and fixed to the inner surface of the front end of the upper case 8a.

  In FIG. 7, reference numeral 63 denotes a power supply circuit for the motor 40. The power supply circuit 63 includes three dropper resistors 64, a fuse 65, a rectifying diode bridge 66, and the like. Each circuit component is mounted on a substrate 67, and the inside of the grip portion A 1 of the case 8. It is fastened and fixed to.

  According to the strator configured as described above, when the switch knob 14 is turned on, the blower fan 41, the heating element 36, and the ion generator 10 are simultaneously driven, and it is displayed that these electric devices are in a driving state. The lamp 15 can be turned on and displayed. The air sucked from the air inlet 18 is pressurized by the blower fan 41 and blown out from the air outlet 19 and the ion outlet 20.

  At the same time, negatively ionized oxygen molecules and water molecules are blown out from the pair of ion outlets 20 provided on the left and right sides of the heating block 5 and the air outlets 19 adjacent to the front and rear sides thereof, so that they pass through the heating blocks 5 and 6. It is possible to increase the hair immediately before and the moisture content of the hair after passing. In other words, even when the hair treatment is performed without pre-treatment, the hair can be made supple and moisturized just before the shampooing, so that moisture is soaked into the dry hair immediately after the shampooing. It can be returned to a certain state. The heating blocks 5 and 6 are heated to a temperature that suits the user's preference, and the hair sandwiched between the blocks 5 and 6 is heated and stretched.

  The present invention is the strator having the above-described configuration, in the ventilation path R from the air suction port 18 opened in the case 8 to the air outlet 19 via the blower fan 41 and between the air blower 19 and the blower fan 41. It is characterized in that the variable resistor 56 constituting the temperature control circuit 11 is arranged in the ventilation path R. More specifically, the substrate 60 on which the variable resistor 56 is mounted is disposed adjacent to the leeward side of the blower fan 41, and the adjustment knob 25 for adjusting the variable resistor 56 is disposed on the outer surface of the processing unit A2 of the case 8. To do.

  The internal temperature of the case 8 in the use state changes within a range from room temperature to less than 140 degrees. Therefore, the temperature coefficient changes due to thermal expansion of a resistance element or a metal part provided inside the variable resistor 56, and the resistance value of the variable resistor 56 changes. That is, when the temperature in the case 8 changes, the resistance value of the variable resistor 56 changes. As a result, the heat generation temperature of the heating element 36 is not constant and varies within a certain range with respect to the set temperature.

  However, if the variable resistor 56 is disposed adjacent to the leeward side of the blower fan 41 as described above, the variable resistor 56 is always exposed to the air flow supplied from the blower fan 41, so that the surface of the variable resistor 56 and The internal temperature only depends on its own resistance heat and the temperature of the air flow, and can maintain a substantially constant temperature state. Therefore, there is no change in the resistance value of the variable resistor 56 due to the change in the temperature coefficient, and the heat generation temperature of the heating element 36 can be stabilized. In particular, when the variable resistor 56 is disposed adjacent to the lee of the blower fan 41, the variable resistor 56 is encased in a strong air flow, so that the temperature state can be maintained in a more stable state.

  The adjustment knob 25 for operating the variable resistor 56 is disposed on the upper surface of the processing unit A2 of the case 8. Therefore, when the hair is swept away by gripping the grip portion A1, the adjustment knob 25 is not accidentally touched, and when the hair is sandwiched between the two sandwiching arms 1 and 2, the adjustment knob 25 is not attached to the head or the hair mass. Since it does not contact, the temperature change of the heating blocks 5 and 6 which a user does not intend can be prevented reliably. Since the adjustment knob 25 can be rotated with the other hand while holding the grip portion A1 with one hand, there is an advantage that the adjustment operation of the adjustment knob 25 can be performed easily and reliably.

  The dropper resistor 64 provided in the power supply circuit 13 of the motor 40 generates heat due to its own resistance heat. By using this heat to heat the air flow fed by the blower fan 41, the surface temperature of the heating blocks 5 and 6 can be prevented from varying depending on the ambient temperature conditions. Basically, if the ventilation path R is between the air inlet 18 and the air outlet 19 of the blower fan 41, the air flow fed by the blower fan 41 is no matter where the dropper resistor 64 is placed. Can be heated.

  More preferably, a dropper resistor 64 is disposed in the ventilation path R between the blower fan 41 and the air inlet 18 as shown in FIG. As described above, when the dropper resistor 64 is arranged on the windward side of the blower fan 41, the air heated by the dropper resistor 64 and the air that has not touched the dropper resistor 64 pass through the blower fan 41. This is because, since the agitation is performed, the temperature of the air flow blown out from the air outlet 19 can be made uniform, and an air flow without temperature unevenness can be blown onto the heating blocks 5 and 6. The variable resistor 56 is exposed to the air flow heated by the dropper resistor 64. However, since the temperature of the air flow is constant, the temperature state is kept stable and the resistance value fluctuates. Can be prevented.

  When the hair sandwiched between the pair of sandwiching arms 1 and 2 is washed away, the flat hair clumps sandwiched between the sandwiching arms 1 and 2 are comb teeth 21 and 34 provided on the left and right sides of the heating blocks 5 and 6, respectively. It is divided into front and back. At this time, the inner and outer comb teeth 21 and 34 are arranged at the same front-rear pitch as shown in FIG. Of course, the front and rear pitches and front and rear positions of the left and right comb teeth 21 and 34 are also aligned. Therefore, even when the tips of the comb teeth 21 and 34 are not in contact with the opposing surfaces of the cases 30 and 8, the hairs can be reliably separated.

  Specifically, even when hair is sandwiched between the cases 30 and 8 facing the comb teeth 21 and 34 and the tips of the comb teeth 21 and 34, the comb teeth 21 projecting downward and the upwards Since the protruding comb teeth 34 can reliably separate the hair from the upper and lower surfaces at the same front and back position, the hair can be guided linearly, and even with strong comb hair, the comb can be effectively stretched and straightened. There is also an advantage that the cuticle can be prevented from being damaged by reducing the number of times the hair is washed by the amount that can effectively make the hair straight.

  By the way, when the inner and outer comb teeth are arranged in a staggered pattern, the hair sandwiched between the tips of the comb teeth and the case facing each comb tooth remains unguided by the comb teeth. Since it passes through the heating block, it is difficult to extend the habit and perform the treatment effectively. When the hair is guided in a square shape by the internal and external comb teeth at different front and rear positions, a strong external force may act to damage the cuticle.

  8 and 9, the adjustment knob 25, the display panel 26, the decorative panel 27, and the decorative sheet 28 are assembled to the case 8 by the following procedure. First, the adjustment knob 25 is assembled to the case 8, and the operation shaft 25 a is inserted and connected to the central connection hole of the variable resistor 56.

  Next, the transparent decorative panel 27 is fitted into the mounting seat 70 formed in the upper surface of the case 8 so as to be recessed, and the engaging claws 71 provided at the three peripheral edges thereof are formed in the engaging holes opened in the front half periphery of the mounting seat 70. Press fit. In this state, the decorative sheet 28 is inserted and loaded between the decorative panel 27 and the mounting seat 70 from the operation knob 25 side.

  Finally, the display panel 26 is put on the outer surface of the operation knob 25, and the engaging claws 72 provided at the three peripheral edges thereof are press-fitted and engaged with the engaging holes opened in the second half peripheral edge of the mounting seat 70, thereby 27 and the movement of the decorative sheet 28 to the rear is restricted.

  As described above, when the decorative panel 27 is assembled to the mounting seat 70 and then the decorative sheet 28 is inserted between them, the decorative panel 27 is assembled with the decorative sheet 28 placed on the mounting seat 70 first. In comparison, the decorative sheet 28 can be reliably prevented from shifting or wrinkling or sagging, and the decorative sheet 28 can always be assembled on the inner surface of the decorative panel 27 in an appropriate state.

  The decorative sheet 28 is made of a sheet material having a metallic appearance on which one side of a transparent plastic sheet such as polycarbonate or polypropylene is formed, and emits an iris color when reflecting light. By covering the outer surface of the decorative sheet 28 with the transparent decorative panel 27, the colored state of the decorative sheet 28 can be seen through the decorative panel 27, so that a deeper colored state can be obtained and a high-class feeling can be obtained. Can demonstrate. If necessary, the decorative sheet 28 can be formed of a metal sheet.

  In the above embodiment, the strator that stretches the hair is described. However, the hair processing apparatus of the present invention may be configured as a waffle for curling straight hair and deforming it. In that case, a corrugated cross-section is formed on each of the opposing surfaces of the heating blocks 5 and 6. In addition to the axial flow fan, a centrifugal fan can be applied as the blower fan 41. In this case, the blower fan 41 is adjacent to the inner surface of the upper case 8a, and the lower end side of the motor 41 is accommodated in the overhang portion 24. . The variable resistor 56 in the present invention includes a semi-fixed resistor. As the heating element 36, a coil heater can be applied in addition to the PTC heater. The adjustment knob 25 can take a form that reciprocates.

  The heating blocks 5 and 6 are preferably provided on both the first and second sandwiching arms 1 and 2, but may be provided at least on the first sandwiching arm 1 side including the ion generator 10. The ion outlet 18 may be formed by one slot that is long to the left and right, a short slot that is intermittent, or a row of holes. One or three or more ion generators 48 can be provided.
