  It is known that, in a hair processing apparatus having a pair of pinching arms, a blower fan and a heat source are housed inside one pinching arm, and heated air is supplied to the hair pinched between the pair of pinching arms (patented). Reference 1). There is also a hair setter in which a steam generating mechanism and a discharge body are arranged inside a case (Patent Document 2).

Japanese Utility Model Publication No. 3-27401 JP-A 8-80215

  The hair treatment device according to Patent Literature 1 houses a blower fan and a heat source block inside the case on the grip side, so that the entire device is finished flat. However, since the ventilation fan is accommodated at the base end of the grip, the ventilation path is lengthened, and it is inevitable that the ventilation resistance increases accordingly. If the ventilation fan is arranged on the brush part side, the ventilation resistance can be reduced, but the thickness of the case at the brush part of one pinching arm increases.

  In the hair treatment device of Patent Literature 2, since the steam generating mechanism and the discharger are arranged inside the case of the brush portion, the brush portion is thicker than the grip side. Since the steam generating mechanism, the discharge body, and the water tank are arranged in the brush portion, there is also a disadvantage that the hair treatment device is weighted when used.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a hair treatment apparatus that can reduce the overall thickness and has no weight when used even though a blower fan for feeding negative ions and a motor for driving the fan are housed in the arms. To provide.

  An object of the present invention is to be able to accommodate a larger fan even though it is a thin hair treatment device, and thus to make the negative ions act evenly on the hair with a large amount of air, to straighten the hair and to curl the straight hair. An object of the present invention is to enable hair treatment such as treatment to be performed effectively, and to enable easy and accurate hair treatment even for dry hair.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a large-sized blower fan for supplying air, so that the blower fan can be rotated at a lower speed to supply a predetermined amount of air, thereby reducing operating noise during use. To provide a simple hair processing device.

Therefore, in the present invention, first and second pinching arms 1 and 2 provided with heating blocks 5 and 6 for pinching hair, an ion generator 10 for generating ions, and an ion outlet from which generated ions are released 17, wherein the first and second pinching arms 1 and 2 are connected to each other via a pivot shaft 3 so as to be swingable and openable. A fan unit 9 for feeding the generated ions is accommodated, and a heating block 5 is disposed on the distal end side of the first sandwiching arm 1 and a heating is performed on the second sandwiching arm 2 corresponding to the heating block 5. The block 6 is disposed, and the fan unit 9 is disposed at a portion that is a wide portion of the first pinching arm 1 and adjacent to the heating block 5 on the side of the swing shaft 3. On the surface of the arm 1 facing the second pinching arm 2, It is bulged toward the scissors arms 2 forming Rutotomoni are recesses 30 is recessed formation receiving a projecting portion 22 to the second scissors arm 2 side, the fan unit 9 is arranged in the interior of the protrusion 22 ing.

According to the present invention, in the hair processing apparatus having the pair of pinching arms 1 and 2, the fan unit 9 for feeding ions is a wide portion of the first pinching arm 1 and the heating block on the side of the swing shaft 3. 5 is arranged in a portion adjacent to, the surface facing the second scissors arm 2 in the first scissors arm 1, Ru is bulged formed projecting portion 22 toward the second scissors arm 2 At the same time, a concave portion 30 for receiving the overhang portion 22 is formed in the second nipping arm 2 side, and the fan unit 9 is arranged inside the overhang portion 22 so that the first nipping arm 1 Avoids increasing the vertical thickness.

  In other words, the heating block 5 and the fan unit 9 are prevented from overlapping one another, and the thickness of the first pinching arm 1 that accommodates these devices is reduced on the processing unit side. The overall thickness of the device can be reduced and the device can be made more compact. In addition, since the fan unit 9 is disposed on the side of the swing shaft adjacent to the heating block 5 so that the position of the center of gravity of the entire apparatus is closer to the grip side, the moment of inertia during use of the hair treatment apparatus can be further reduced, and No easy-to-use hair treatment device is obtained.

  If the overhanging portion 22 is formed on the surface of the first nipping arm 1 facing the second nipping arm 2, and the fan unit 9 is disposed inside the overhanging portion 22, the first nipping arm The large-sized blower fan 37 can be accommodated in the first pinching arm 1 while avoiding the thickness of the entire processing section side of the arm 1 from being increased, so that a large amount of hair can be stored in a thin hair processing apparatus. Pressurized air can be delivered to the hair with negative ions. When the air supply amount is constant, the blower fan 37 may be driven at a lower speed, so that the fan noise is reduced by that amount and the hair processing device can be quieter.

  At the time of hair treatment, negative ions act on the hair together with a large amount of air to neutralize the positively charged hair and prevent the hair from sticking, and also allow the negative ions to penetrate the hair and make the hair supple, Hair treatments such as straightening and straightening of hair can be effectively performed, and even dry hair can be easily and accurately treated. Since the overhanging portion 22 is provided on the joint surface side with the second sandwiching arm 2, the facing gap between the first sandwiching arm 1 and the second sandwiching arm 2 is formed by the overhanging portion 22 on the heating block 5.6 side. And the grip side, the hair sandwiched between the heating blocks 5 and 6 can be prevented from being unnecessarily spread, and the hair can be effectively treated. (Claim 1)

  1 to 7 show an embodiment in which the present invention is applied to a strator (hair treatment device). A strator is used to straighten curly or hazy hair.

  1 and 2, the strator is configured by connecting base ends of first and second sandwiching arms 1 and 2 which are vertically opposed to each other with a swing shaft 3. The two pinching arms 1 and 2 can swing open and close around a swing axis 3, and can be freely opened and urged by a compression coil type spring 4 provided between the base ends of the arms 1 and 2 to be in a free state. Is held in the open position shown by the solid line in FIG. By gripping the grip portions of the two holding arms 1 and 2 in the open posture with one hand, the hair can be held between the upper and lower heating blocks 5 and 6 provided on the opposing surfaces of the two holding arms 1 and 2 respectively. it can.

  In FIG. 3, the first pinching arm 1 is composed of a case 8 in the shape of a blade, a fan unit 9, an ion generator 10 and a heating block 5 disposed inside the case 8. On one side of the center of the grip portion of the first pinching arm 1, a switch knob 11 that slides left and right to switch the power switch on or off and an indicator light 12 are arranged (see FIG. 1). When the switch knob 11 is turned on, the fan unit 9, a heating element 34, which will be described later, and the ion generator 10 are driven at the same time, and the display lamp 12 can light and display that these electric devices are in a driving state.

  The case 8 is formed in a hollow case shape by connecting an upper case 8a and a lower case 8b, which are divided into two parts, into a lid shape. The upper case 8a is made of a boat-shaped container-shaped plastic molded product having an open lower surface, and the grip side thereof is formed thin as shown in FIG. 2, whereas the heating block 5, the fan unit 9, and the ion generator 10 are provided. The side of the processing section to be accommodated is formed wide.

  The lower case 8b is formed of a shallow dish-shaped plastic molded product having the same outline as the upper case 8a, and is inclined obliquely downward so that the processing unit side is located below the grip side when viewed from the side. Accordingly, the vertical dimension of the case 8 on the processing unit side is slightly larger than the vertical dimension of the grip side.

As shown in FIG. 2, a suction port 15 for increasing the air-blowing efficiency of the fan unit 9 is opened near the swing axis 3 on the bottom wall on the grip side of the lower case 8b, and the bottom wall on the processing unit side is heated. An opening for exposing the block 5 to the outside of the case is provided. As described above, when the air suction port 15 is opened on the lower surface of the lower case 8b facing the second pinching arm 2, the outer surface of the air suction port 15 is closed by the user's hand in a state where the grip portion is gripped by hand. Peeling can be reliably prevented.

  In FIG. 2, a group of air outlets 16 for pressurized air supplied by the fan unit 9 and an ion air outlet 17 are opened on both left and right sides of the opening for the heating block 5. The pressurized air outlet 16 is opened intermittently along the long side of the heating block 5, and the ion outlet 17 is formed at the front and rear center of the outlet 16.

  A group of hair styling comb teeth 18 and hair styling ribs 19 are provided on both left and right sides of the lower case 8b facing the heating block 5 so as to protrude in a straight line so as to face gaps between them. The comb teeth 18 and the hair styling ribs 19 are provided for combing the hair before and after passing through the heating blocks 5 and 6 so that the entangled hair is neatly combed through. When the comb teeth 18 and the hair trimming ribs 19 are projected in a straight line in a staggered state, excessive tension tends to be applied to the hair. However, as shown in FIG. 6, all of the hair trimming ribs 19 (or every other one). If the hair shaping rib 19 may be shorter than the comb teeth 18, it is possible to prevent excessive tension from being applied to the hair.

  As shown in FIG. 1 and FIG. At a position adjacent to the heating block 5 on a surface facing the second sandwiching arm 2, a knob-shaped projection 22 is formed so as to bulge toward the second sandwiching arm 2.

  The overhang portion 22 includes a main wall 23 formed of a partially arcuate surface, and an inclined end wall 24 formed of a three-dimensional plane that connects the front and rear ends of the main wall 23 and the lower surface wall of the lower case 8b smoothly. I do. As shown in FIG. 4, the main wall 23 is formed so as to protrude downward from a peripheral wall of the heating block 6 on the second pinching arm 2 side. The boundary between the lower surface wall of the lower case 8b and the inclined end wall 24 is formed in an arc shape toward the heating block 5 as shown in FIG.

  When the overhang portion 22 is provided on the lower surface side of the case 8 as described above, the vertical distance between the overhang portions 22 in the case 8 can be increased, so that the fan diameter of the blower fan 37 housed therein is reduced. Can be larger. This means that a larger amount of pressurized air can be supplied without increasing the driving speed of the blower fan 37. Further, the fan noise can be reduced by the lower drive speed.

  From the viewpoint of the case structure, the housing of the fan unit 9 can be prevented from protruding toward the upper surface of the upper case 8a. Can be simplified. The overhanging portion 22 receives the hair sandwiched between the two holding arms 1 and 2 and moves to the side of the air intake 15 to prevent the hair from being sucked from the air intake 15. In a state where the hair is sandwiched, it is also useful to restrict the first and second sandwiching arms 1 and 2 from shifting in the left-right direction. Incidentally, even if the air inlet 15 is located on the upper case 8a side, it is still possible to prevent the hair sandwiched between the pair of heating blocks 5 and 6 from being unnecessarily spread by the overhang portion 22, and such Even if it is a structure, the overhang part 22 functions effectively at the time of hairdressing. That is, the lower case facing the second pinching arm 2 is that the air inlet 15 can reliably prevent the outer surface of the air inlet 15 from being closed by the user's hand when the grip portion is gripped by hand. It is preferable that the air intake port 15 be opened on the lower surface of the fan 8b. However, the air inlet 15 is not limited to this.

  The second pinching arm 2 has a blade-shaped case 29 formed in the same outline shape as the first pinching arm 1, and a heating block fixed to the upper surface of the first case 29 corresponding to the heating block 5 of the pinching arm 1. 6. The first case 29 includes a shallow dish-shaped lower case 29b having an open upper surface, and an upper case 29a for closing the upper open surface of the lower case 29b. Each of the upper and lower cases 29a and 29b is a plastic molded product.

  The processing portion side of the upper case 29a and the lower case 29b bulges to the lower surface side along the lower surface shape of the lower case 8b of the first pinching arm 1. An opening for exposing the heater unit 6 to the outside of the case is formed on the upper surface of the upper case 29a, and a concave portion 30 for receiving the overhang portion 22 is formed adjacent to the opening (see FIG. 7). ). When the concave portion 30 for receiving the overhang portion 22 is formed in the second sandwiching arm 2 side, the facing gap between the first sandwiching arm 1 and the second sandwiching arm 2 is formed into the overhang portion fitted into the recess portion 30. At 22, the overhanging section 22 separates the heating block 5.6 into the grip side and separates the hair between the heating blocks 5.6 from moving toward the air inlet 15. it can. Therefore, it is possible to reliably prevent the hair from being sucked into the air inlet 15, and to prevent the hair sandwiched between the pair of heating blocks 5 and 6 from unnecessarily spreading, thereby effectively performing the hair treatment. In addition, since the first and second pinching arms 1.2 can be prevented from moving in the left and right directions while the hair is sandwiched, the heating blocks 5 and 6 are always directly opposed to each other to effectively treat the hair. I can do it.

  In FIG. 3, the heating blocks 5 and 6 include a rectangular box-shaped inner case 33 that is long in the front and rear directions, a heating element 34 loaded in the inner case 33, and a heating element 34 fastened and fixed to the inner case 33. It includes an outer case 35 made of a metal plate which is cooperatively pinched and fixed, and an insulating sheet disposed between the heating element 34 and the outer case 35, and is configured as one unit component.

  The heating element 34 is composed of a pair of front and rear PTC heaters in the form of a flat block, and is fixed and held non-movably by a holder provided in the case. The outer case 35 sandwiches the hair between its flat surfaces and heats the hair by the heat conducted from the heating element 34. Note that the upper and lower heating blocks 5 and 6 have the same structure, and are used by being attached to the respective sandwiching arms 1 and 2 in a state of being turned upside down.

  4 and 5, the fan unit 9 includes an axial-flow-type blower fan 37, a motor 38 for driving the blower fan 37 to rotate, and a holder 39 for supporting these. The holder 39 is integrally provided with a wind tunnel 40 for accommodating the blower fan 37 and a holder base 41 into which the motor 38 is fitted and loaded. As shown in FIG. 4, the rear end of the holder base 41 is connected to the upper case 8a. The upper case 8 is integrated with the upper case 8 by receiving with a claw 42 provided on the inner surface of the upper case 8 and screwing a screw seat 43 (see FIG. 5) provided on both sides of the outer surface of the wind tunnel portion 40 to a boss of the upper case 8a. When the blower fan 37 is driven in the wind tunnel 40, the air flow can be adjusted in the wind tunnel 40 and the directivity can be given, so that the fan efficiency is improved. In addition, by having the wind tunnel 40, the gap between the wind tunnel 40 and the fan 37 can be kept constant over the entire circumference as shown in FIG. 7, so that the fan efficiency is further improved. A state in which the fan unit 9 includes an axial-flow-type blower fan 37 and a motor 38 that rotationally drives the blower fan 37, and a part of a rotation region of the blower fan 37 is located in a space surrounded by the overhang portion 22. Since the fan unit 9 is disposed in the first pinching arm 1, the entire amount of pressurized air generated by the blower fan 37 can be sent to the heating block 5 without waste. As compared with a case where pressurized air is generated by using the blower fan, air for ion transport can be supplied more efficiently, and there is no interference between airflows in the first pinching arm 1. Further, a part of the air blown from the blower fan 37 can forcibly cool the overhang portion 22 adjacent to the heating block 5, so that the overhang portion 22 is sandwiched between the overhang portion 22 and the second sandwiching arm 2. It is possible to reliably prevent the hair from being curled by the overhang portion 22.

  In the ion generator 10, as in the case of the heating block 5, all of the components are combined as one unit component. 4, the ion generator 10 includes an electric holder 45 made of a plastic molded product, a circuit board 46, a transformer 47, and a pair of left and right discharge bodies 48 mounted on the electric holder 45, respectively. Bosses 49 for assembling the discharge body 48 are integrally provided on both left and right sides of the electrical holder 45 (see FIG. 6).

  In FIG. 8, electronic components constituting a rectifier circuit for half-wave rectification of a commercial power supply (100 V) and a pulse generation circuit for converting half-wave rectification into pulse voltage / current are mounted on a circuit board 46. The pulse voltage / current output from the pulse generation circuit is boosted to, for example, 4 kV by the transformer 47 and then supplied to the discharge body 48. In FIG. 6, the discharge body 48 includes a needle-shaped center electrode 51 fixed to the center of the boss 49 of the electrical holder 45, a cylindrical peripheral electrode 52 fixed to the outer peripheral surface of the boss 49, and an inner periphery of the boss 49. And an insulating cylinder 53 fixed to the surface.

  Oxygen molecules and water molecules floating in the air around both electrodes 51 and 52 are negatively ionized by the discharge action between the center electrode 51 and the peripheral electrode 52, and are discharged from the ion outlet 17 together with the air flow. Since the ion outlet 17 and the outlet 16 adjacent to the ion outlet 17 communicate with each other inside the case, some of the negative ions are also blown out from the outlet 16. The negative ions containing water neutralize the positively charged hair and prevent the hair from becoming loose. Furthermore, it penetrates deep inside the hair and rehydrates it. 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 5.6, some of the moisture that has penetrated into the hair evaporates, but the hair that has passed through the heating blocks 5.6 can be re-exposed to negative ions containing moisture to regain moisture. .

  In FIG. 5, the transformer 47 and the left and right discharge bodies 48 are connected via a high-voltage lead wire 56 derived from the transformer 47 and left and right branch lead wires 57 each having one end connected to the center electrode 51.

  More specifically, the conductors of the output end of the high-voltage lead wire 56 and the input ends of the left and right branch lead wires 57 are simultaneously twisted and then soldered. Then, as shown in FIG. 6, the soldered connection portion C is inserted into the concave portion 58 provided in the electrical equipment holder 45, and the surrounding space is filled with an insulator 59 such as a silicon adhesive to insulate the connection portion C. .

  In this way, if the connection portion C is insulated and shielded from the others in the concave portion 58, the connection portion C can be prevented from floating by preventing the floating movement of the connection portion C, and the conductive wire can be prevented from being exposed. Unnecessary discharge can be reliably prevented from occurring between the connection portion C and the surrounding electrode 52, and the negative ions generated by the discharge body 48 can be effectively generated by that much.

  According to the strator having the above structure, oxygen ions and water molecules that are ionized negatively are blown out from the pair of ion outlets 17 provided on the left and right sides of the heating block 5, so that the hair just before passing through the heating blocks 5 and 6 is removed. The moisture content of the hair after passing through can be increased. In other words, even when performing hair treatment without pre-treatment, it is possible to effectively make the hair supple and hydrated immediately before the hair straightening, and to dry the hair immediately after the hair straightening. Moisture can be soaked in hair to restore it to a moist state.

  Negative ions can act on the hair portion above and below the hair portion sandwiched between the heating blocks 5 and 6 at the same time. Therefore, when using the strator with the right hand and when using it with the left hand In any case, negative ions can be equally applied to the hair, and there is no restriction on the direction in which the hair treatment device is used.

  As shown in FIG. 4, the ion generator 10 as a unit component is housed in a space between the heating block 5 and the upper case 8 a and is attached to the upper case 8 a with a small gap from the heating block 5. Fastened and fixed. A fan unit 9 is arranged adjacent to the end of the device 5 or 10 on the side of the swing shaft. Therefore, a part of the air flow sent from the fan unit 9 moves to pass through the gap, and is then blown out of the case from the left and right blowout ports 16. In other words, the convection heat released from the heating block 5 can be prevented from staying in the gap, and the circuit board 46 can be forcibly cooled to prevent the electronic components mounted on the circuit board 46 from overheating. The temperature of the air flow blown from the outlet 16 or the ion outlet 17 is lower than the temperature of the hair heated by the heating blocks 5 and 6. Therefore, the hairs that have been hampered by the heating blocks 5 and 6 are rapidly cooled by the airflow blown out from the outlet 16 and the ion outlet 17, and the hampering effect can be improved accordingly.

  In the above-described embodiment, the description has been given of the strator for extending the hair. However, the hair processing apparatus of the present invention may be configured as a waffle for performing a straightening process on a straight hair. In that case, corrugations are formed on the facing surfaces of the heating blocks 5 and 6 respectively.

  As the blower fan 37, a centrifugal fan can be used in addition to the axial flow fan. In this case, the blower fan 37 is adjacent to the inner surface of the upper case 8a, and the lower end of the motor 38 is housed in the overhang portion 22. . The heating element 34 is not limited to an electric type such as a PTC heater and a coil heater, and may be a gas type or a heat generating type using an oxidation reaction of iron. The heating blocks 5 and 6 are preferably provided on both the first and second holding arms 1 and 2, but may be provided on at least the first holding arm 1 provided with the ion generator 10. The ion outlet 18 may be formed of one long slot on the left and right, a short slot that is intermittent, or a row of holes. In the above-described embodiment, the first pinching arm 2 and the second pinching arm 3 are urged to swing freely by the spring 7, but it is not necessary. The recess 30 can be formed as a trough-shaped recess crossing the case 29 left and right, and need not be the mortar-shaped recess described in the embodiment.

  Further, in addition to forcibly cooling the inside of the case 8, the inside of the second pinching arm 3 can be forcibly cooled. In this case, the two cases 8 and 29 are communicated with each other at a connection portion between the two so as to be able to ventilate. The air is passed through the case 29 from the air suction port 15 at the tip, and flows into the case 8 via the connecting portion between the two cases 8 and 29. Thereafter, the intake air is blown out by the blower fan 9 from the outlet 16 and the ion outlet 17 together with the ions. By forming such a circulation path, the heat staying in both cases 8.29 can be forcibly discharged. One or three or more discharge bodies 48 can be provided. The ion generator 10 is preferably formed as a unit component as described in the embodiment, but is not necessarily required, and can be directly assembled inside the case according to the structure of the case 8.
