  The present invention relates to a hair processing apparatus for cutting body hair such as beard, hair, or unwanted hair. The hair processing apparatus according to the present invention includes a shearing section that cuts hair by a shearing action, and a thermal cutting part that cuts hair by a thermal cutting action.

  An electric razor is well known as a representative example of a hair processing apparatus having a shearing portion, in which the beard is cut by the shearing action of the outer blade and the inner blade. Further, a hair processing apparatus for cutting body hair by a thermal cutting action is known from Patent Document 1. There, a heater is disposed between a pair of comb teeth so that the hair captured by the comb teeth can be thermally cut by the heater.

JP-A-10-234462 (paragraph number 0011, FIG. 5 and FIG. 6) Japanese Patent Laid-Open No. 08-289814 (paragraph number 0037, FIG. 3) Japanese Patent Laid-Open No. 06-181811 (paragraph number 0010, FIG. 1)

  The hair processing apparatuses of Patent Documents 1 to 3 mainly cut single hair such as dead hair of legs and arms, or hair, and are therefore not suitable for use in cutting a large amount of beard. This is because it is not impossible to thermally cut a group of long whiskers captured by comb teeth with a heater, but the length of the cut whiskers cannot be reduced below a certain level. On the other hand, hair treatment devices represented by electric razors can cut a large amount of whiskers close to the skin, but long beards that exceed several centimeters, such as unwanted hair, can be cut between the outer and inner blades. It was difficult to introduce even a cross section, and there was a problem in that it was difficult to cut such a long beard.

  The object of the present invention includes a shearing section and a thermal cutting section, and can effectively cut body hair in any length and in any state. An object of the present invention is to provide a hair treatment apparatus that can perform its function.

The thermal cutting head 36 can float up and down with respect to the thermal cutting base 35 at each switching position between the first position and the second position.

  The hair processing head 2 is provided with a blower fan 16 for supplying pressurized air toward the skin surface.

  As shown in FIGS. 6 and 7, the cutting unit 37 includes a central shaft 54 that is rotatably supported, and a first heating element 56 that is configured by one heating wire that is supported around the central shaft 54. And a second heating element 57 composed of a plurality of heating lines. The cutting unit 37 is rotated around its central axis 54 so that one of the first heating element 56 and the second heating element 57 can be selectively switched to the use posture.

  A furrow body 50 is provided on the outer surface of the thermal cutting head 36. As shown in FIG. 15, a cutting unit 37 having a heating element 56 inside the thermal cutting head 36 and a motor 76 for rotating the cutting unit 37 are arranged. The hair is thermally cut while the cutting unit 37 is driven to rotate.

  As shown in FIG. 16, the cutting unit 37 includes a central shaft 54, a plurality of heat ray holders 55 projecting around the central shaft 54, and a heating element 56 supported by the plurality of heat ray holders 55. The heat ray holder 55 also serves as a tension body that holds the heating element 56 in a tensioned state.

  A raised body 80 for raising body hair is provided around the central axis 54 of the cutting unit 37 (see FIG. 16).

  The energization state to the heating element 56 is intermittently turned on / off to thermally cut the hair (see FIG. 19).

  The contact terminals 60 and 61 are fixed to the peripheral surface of the shaft end of the central shaft 54. A fixed terminal 62 that slides on the contact terminals 60 and 61 to supply a driving current to the heating element 56 is provided on the outer peripheral surface of the central shaft 54, and the cutting unit 37 rotates so that the heating element 56 is energized. Turn on and off mechanically. The central shaft 54 may be provided with at least one pair of left and right contact terminals 60.

  The body case 1 and / or the hair processing head 2 is provided with a human body detection sensor 68 that detects that the thermal cutting head 36 has come into contact with the human body. Only when the human body detection sensor 68 detects that it has contacted the human body, a drive current is supplied to the heating element 56 (see FIG. 10).

  The main body case 1 is provided with a rotation speed adjuster 91 that changes the rotation speed of the cutting unit 37 (see FIG. 24). The rotational speed adjuster 91 is adjusted so that the rotational speed of the cutting unit 37 can be changed within a predetermined range.

  The main body case 1 is provided with a current adjuster 93 that adjusts the current value supplied to the heating element 56. As the rotational speed of the cutting unit 37 increases, the current adjuster 93 is adjusted so that the amount of current supplied to the heating element 56 can be increased.

  In the hair processing apparatus of the present invention, the hair processing head 2 is provided with the shearing portion 14 and the thermal cutting portion 15, so that the short hair, the long hair, and the dead hair are caused by the shearing action of the shearing portion 14 and the thermal cutting action of the thermal cutting portion 15. Hair, such as long hair, can be effectively cut according to the state of the hair. Therefore, it is possible to provide a hair processing apparatus that can exhibit a higher level of hair cutting function than conventional devices. Further, when a beard is shaved with the hair processing apparatus of the present invention, a long beard can be cut quickly by the shearing portion 14 after the long beard is effectively cut by the thermal cutting portion 15, so that the long beard is sheared. Compared to the case where the cutting is gradually performed at the portion 14, the whisker can be cut efficiently. By using the thermal cutting part 15 together, the cutting load of the shearing part 14 can be greatly reduced, so that the wear and wear of the parts constituting the shearing part 14 can be suppressed and the life can be improved.

  According to the hair processing apparatus that supports the thermal cutting part 15 at the first position and the second position so that the position can be changed, and moves the thermal cutting part 15 at the first position away from the head frame 10 from the position of the shearing part 14. The thermal cutting part 15 can be used in the first position without being disturbed by the shearing part 14. Accordingly, it is possible to accurately and efficiently cut a long beard or long hair by the thermal cutting unit 15.

  Furthermore, if the thermal cutting part 15 can be repositioned to the third position, and the thermal cutting part 15 in the third position is brought closer to the head frame 10 than the shearing part 14, the thermal cutting part 15 is not disturbed, and shearing is performed. By applying the part 14 to the skin surface, hair, particularly short hair, can be effectively cut.

  When the thermal cutting unit 15 is switched to the third position and the energization to the cutting unit 37 is cut off, the thermal cutting unit 15 prevents wasteful power consumption when the hair is cut by the shearing unit 14. it can. In addition, since the heat generating action of the thermal cutting part 15 positioned at the third position can be stopped reliably, even if the finger touches the thermal cutting part 15 when cutting the hair with the shearing part 14, the burns are not burned. The safety of the hair processing apparatus can be improved without worry.

  When the thermal cutting head 36 is float supported by the head frame 10 and the float spring 51, when the thermal cutting head 36 is strongly pressed against the skin surface, the thermal cutting head 36 is moved toward the head frame 10 and acts on the skin surface. Pressure can be relieved. Therefore, it is possible to prevent a part of the skin surface from entering the inside of the thermal cutting head 36 and come into contact with the heating element 56, thereby improving the safety of the hair processing apparatus.

  After the thermal cutting head 36 is displaced to the float limit position, the pressure acting on the skin surface cannot be relieved by the float structure, and a part of the skin surface enters the thermal cutting head 36 and the heating element 56. There is a risk of contact. However, if the cutting unit 37 is de-energized while being displaced to the float limit position, the heating action of the heating element 56 can be stopped and the temperature can be lowered, so that part of the skin surface enters the thermal cutting head 36. And avoiding burns and improving the safety of the hair treatment apparatus.

  When the thermal cutting head 36 is floated up and down with respect to the thermal cutting base 35 in a state where the thermal cutting base 35 is switched between the first position and the second position, the thermal cutting head 36 is used alone, or In the state of using together, the pressure which acts on the skin surface which contacts the thermal cutting head 36 can be relieved. Therefore, whenever the thermal cutting head 36 is in a usable state, the thermal cutting head 36 is moved to the thermal cutting base 35 side to prevent a large pressure from acting on the skin surface, and a part of the skin surface. Can be prevented from entering the inside of the thermal cutting head 36 and coming into contact with the heating element 56.

  When the blower fan 16 is provided in the hair processing head 2 so that the air pressurized by the blower fan 16 can be fed toward the skin surface, the hair is cut by the thermal cutting head 36 while cooling the skin surface with the pressurized air. it can. Moreover, since the skin surface warmed by the heat generating body 56 provided in the thermal cutting head 36 can be cooled with pressurized air, the thermal hair can be comfortably cut by the thermal cutting head 36.

  When the cutting unit 37 is rotated around the central axis 54 so that the first heating element 56 and the second heating element 57 can be selectively switched to the use posture, the heat generation suitable for the body hair state is achieved. The body can be selected for thermal cutting. For example, when thermally cutting dense bristles, heat is cut by the second heating element 57 constituted by a plurality of heating wires, and when cutting thin and long hair, the first heating wire constituted by one heating wire is used. 1 cut by heat with the heating element 56. The difference in the characteristics of the first heating element 56 and the second heating element 57 may be a difference in heat capacity, a difference in cooling characteristics, or the like in addition to the heating temperature.

  According to the body hair treatment device that thermally cuts the hair while the cutting unit 37 is driven to rotate, the heating element 56 can approach the skin surface and cut the body hair each time the cutting unit 37 rotates once. 56 leaves | separates from a skin surface simultaneously with heat-cutting hair. Therefore, compared with the case where the hair is thermally cut while the heating element 56 is directly facing the skin surface, the time during which the skin surface is exposed to the heat of the heating element 56 can be shortened, and thus the skin surface can be heated. It can be surely prevented and the hair can be thermally cut more comfortably.

  In the cutting unit 37 including the central shaft 54, the plurality of heat ray holders 55, and the heating element 56, if the heating element 56 is held in tension using the elasticity of the heat ray holder 55, there is no need to provide a separate tension body. Thus, the structure of the cutting unit 37 can be simplified accordingly. Further, the cost required for manufacturing the cutting unit 37 can be reduced as much as the tension body can be omitted, and unnecessary power consumption by the tension body, which is inevitable when the tension body is provided, can be eliminated.

  When the raised body 80 is provided around the central axis 54 of the cutting unit 37, the hair or the combed hair that has fallen along the skin surface is forcibly raised by the raised body 80, and the hair is thermally cut more effectively. be able to. Further, it is possible to well prevent the hair that has been thermally cut from jumping off by the raised body 80 and the hair that has been thermally cut into the thermal cutting head 36.

  In the hair treatment apparatus that thermally cuts the hair while rotating the cutting unit 37, when the energization state to the heating element 56 is intermittently turned on / off, the driving current is continuously supplied to the heating element 56. Thus, the power consumption in the thermal cutting unit 15 can be reduced. In addition, by intermittently turning on / off the energized state, the hair can be thermally cut while being kept at an appropriate temperature while preventing the heating element 56 from overheating.

  When the contact terminals 60 and 61 are fixed to the peripheral surface of the shaft end of the center shaft 54 and the energization state to the heating element 56 is mechanically turned on / off using the rotation of the cutting unit 37, the energization state It is possible to simplify the power supply structure that changes the power supply intermittently and reduce the cost.

  If a human body detection sensor 68 is provided in the hair processing apparatus, and a driving current is supplied to the heating element 56 only in a state where the human body detection sensor 68 detects that it has contacted the human body, the thermal cutting head 36 is moved away from the skin surface. Heat generation of the heating element 56 can be stopped. Therefore, it is possible to reduce the amount of power consumed by the heating element 56 and eliminate the wasteful consumption of the battery 3. Further, when the hair is thermally cut, even if the finger touches the thermal cutting head 36 of the hair processing apparatus placed on the table, it is possible to prevent burns due to the heat of the heating element 56.

  When the rotational speed adjuster 91 is adjusted so that the rotational speed of the cutting unit 37 can be changed within a predetermined range, the driving rotational speed of the cutting unit 37 can be adjusted to the rotational speed desired by the user. . Alternatively, by adjusting the drive rotation speed of the cutting unit 37 according to the thickness and hardness of the body hair, the density of the body hair, etc., the thermal cutting conditions by the heating element 56 can be variously changed to accurately perform the thermal cutting of the body hair. It can be carried out.

  When the current adjuster 93 is adjusted in accordance with the increase in the rotation speed of the cutting unit 37 to increase the amount of current supplied to the heating element 56, the driving unit 56 increases when the driving rotational speed of the cutting unit 37 increases. The heat generation temperature of the heating element 56 can be maintained at an appropriate temperature by correcting the gradual decrease in temperature. Therefore, even when the rotation speed of the cutting unit 37 is changed within a predetermined range, the heat generation temperature of the heat generating body 56 is maintained at an appropriate temperature, and the hair cutting by the heat generating body 56 can always be suitably performed.

Since the two heating lines of the second heating element 57 have the same resistance value as that of the heating line of the first heating element 56, the temperatures of the heating lines of the second heating element 57 are different from each other. It becomes the same as the temperature of 56 exothermic lines. Accordingly, although the power consumption is doubled, the bristles can be quickly thermally cut by the two heating wires.

  As described above, the thermal cutting base 35 can change the posture between the first position and the third position. The thermal cutting head 36 is float supported by the thermal cutting base 35 and the fourth float spring 51 and can move up and down within a certain range. In order to detect the vertical position of the thermal cutting base 35 and the thermal cutting head 36 as described above, the engagement claw 46 turns on each of the engagement recesses 47 on the front wall side of the guide frame 40 as shown in FIG. Three position detection switches (position sensors) 67 to be operated are provided. Also, a human body detection switch (human body detection sensor) 68 that is turned on by a thermal cutting head 36 and detects the vertical position of the head 36 above and below the front wall of the holding frame 38 constituting the thermal cutting base 35, and a float A limit switch (float limit sensor) 69 is provided. Three position indicator lamps 70 are provided on the top and bottom of the front wall of the head frame 10 to light up corresponding to the vertical position of the thermal cutting base 35.

  As shown in FIG. 3A, when the thermal cutting base 35 is in the first position, the uppermost position detection switch 67 is turned on by the engaging claw 46, and the upper position indicator lamp 70 is lit. . Similarly, in a state where the thermal cutting base 35 is in the second position, the position detection switch 67 at the upper and lower center is turned on by the engaging claw 46, and the position indicator lamp 70 at the upper and lower center is turned on. When the thermal cutting base 35 is in the third position, the lower position detection switch 67 is turned on by the engaging claw 46 and the lower position indicator lamp 70 is lit.

  The human body detection switch 68 is turned on by the thermal cutting head 36 in a state where the thermal cutting head 36 is pushed down against the urging force of the fourth float spring 51, so that the hair body 50 comes into contact with the skin surface of the human body. Is detected. The float limit switch 69 is turned on by the thermal cutting head 36 in a state where the thermal cutting head 36 is pushed down to the lower limit position against the urging force of the fourth float spring 51, and the bristle body 50 is moved to the human body. Detect that there is a risk of eating into the skin.

  FIG. 9 shows the relationship between the control circuit 71 mounted on the control board 4 and each of the switches 7, 67, 68, and 69, the control circuit 71 and the motors 5 and 6, the first heating element 56, the second heating element 57, etc. An outline of the relationship between the load device and the relationship between the control circuit 71 and each of the indicator lights 9 and 70 is shown. Hereinafter, details of the driving state of each load device and each display by the control circuit 71 will be described based on the timing charts of FIGS. 10 to 12.

  FIG. 10 is a timing chart when the thermal cutting base 35 is switched to the uppermost first position. At the same time when the push button 8 is pushed and the main switch 7 is turned on, the motor 5 for the blower fan 16 is turned on. Is activated. The motor 5 for the shearing portion 14 is maintained in a stopped state. At the same time, the energization indicator lamp 9 and the upper position indicator lamp 70 are turned on. In this state, when the user puts the furrow body 50 on the skin surface, the thermal cutting head 36 is pushed against the fourth float spring 51, so that the human body detection switch 68 is switched on and the first heat generation is performed. Energization of the body 56 (or the second heating element 57) is started. The user can perform thermal cutting mainly by bringing the long hairs or unwanted hairs into contact with the first heating element 56 by sliding the bristle body 50 along the skin surface. At this time, since a normal temperature airflow is blown from the blower fan 16 through the air guide path 17 to the skin surface, it is possible to prevent the skin surface from being heated by the heat of the first heating element 56.

  If the bristle body 50 during thermal cutting is strongly pressed against the skin surface, the skin surface may enter the inside of the thermal cutting head 36 through the introduction opening 49 and come into contact with the first heating element 56. In order to avoid such a problem, when the thermal cutting head 36 is pushed to the limit position against the biasing force of the fourth float spring 51, the float limit switch 69 is switched to the on state and receives an on signal. The control circuit 71 stops energization of the first heating element 56. Even in the state where the energization is stopped, the supply of the airflow by the blower fan 16 is continuously performed, so that the temperature of the first heating element 56 rapidly decreases. Therefore, it can be eliminated that the skin surface comes into contact with the first heating element 56 and is burned. When the pressing force against the skin surface of the furrow body 50 is decreased, the float limit switch 69 is switched to the off state, and energization to the first heating element 56 is resumed. Further, when the hair body 50 is separated from the skin surface, the human body detection switch 68 is switched to the off state, and thus energization to the first heating element 56 is stopped. Thereafter, by repeating the above, long hair or unwanted hair is thermally cut. Finally, when the push button 8 is pushed in and the main switch 7 is switched to the OFF state, the supply of current to all members is stopped.

  FIG. 11 is a timing chart when the thermal cutting base 35 is switched to the second position at the center in the vertical direction. There, the point that the motor 5 for the blower fan 16 and the motor 6 for the main blade 20 and the sub blade 21 are simultaneously activated at the same time when the push button 8 is pushed and the main switch 7 is turned on. Different from the timing chart. At the same time as the main switch 7 is turned on, the energization indicator lamp 9 and the vertical center position indicator lamp 70 are turned on. As described above, in the second position, the main blade 20, the sub blade 21, and the cutting unit 37 cooperate to perform beard cutting. The control of the energization state for the first heating element 56 that accompanies the turning on / off of the human body detection switch 68 and the float limit switch 69 is the same as the control content described in the timing chart of FIG. Is omitted.

  FIG. 12 is a timing chart when the thermal cutting base 35 is switched to the lowermost third position. In the state where the thermal cutting base 35 is switched to the third position, the position detection switch 67 positioned at the lowermost position is switched to the on state. Therefore, when the main switch 7 is switched to the on state, the motor 5 for the blower fan 16 and the motor 6 for the main blade 20 and the sub blade 21 are activated at the same time, and the first heating element 56 is energized. Stops unconditionally. That is, in the state where the thermal cutting unit 15 is switched to the third position, the energization to the cutting unit 37 is cut off regardless of the switch state of the human body detection switch 68 and the thermal cutting unit 15 is kept in the standby state. Is done. Since the bottom surface of the thermal cutting head 36 at this time is received by the upper end of the guide pin 41 as shown in FIG. 4, it does not move further downward. At the same time as the main switch 7 is turned on, the energization indicator lamp 9 and the lowermost position indicator lamp 70 are turned on. In the third position, when the main blade 20 and the sub blade 21 cooperate to cut the whiskers and the main switch 7 is switched to the OFF state, the supply of current to all members is stopped.

  According to the hair processing apparatus configured as described above, since the shearing portion 14 and the thermal cutting portion 15 are provided in the hair processing head 2, the shearing portion 14 and the thermal cutting portion 15 are used in combination according to the state of the beard and body hair. The beard and body hair can be cut, or either the beard or body hair can be cut. Therefore, according to the above-described body hair treatment device, it is possible to effectively cut beards and body hairs of any length, and it is possible to exhibit an advanced body hair cutting function as compared with conventional electric razors or body hair treatment devices.

(Example 2) The hair processing apparatus which concerns on Example 2 is shown in FIG. 13 thru | or FIG. The hair processing apparatus of the second embodiment is different from the first embodiment in the structure of the main blade 20, the structure of the cutting unit 37, the structure of the human body detection sensor 68, and the like. The blower fan 16, the motor 5, and the sub blade 21 in the first embodiment are omitted. As shown in FIG. 14, the main blade 20 is composed of a blade support base 22, an inner blade 23 composed of a slit blade, and an outer blade 24 composed of a mesh blade, and the output shaft of the motor 6. The eccentric cam 73 and the vibrator 74 fixed to each other convert the motor power into reciprocating power to drive the inner blade 23 back and forth (see FIG. 13). The blade support base 22 is supported by a second float spring 26 composed of the head frame 10 and a compression coil spring so as to freely float up and down.

  As shown in FIGS. 14 to 16, the cutting unit 37 includes a center shaft 54, a pair of left and right heat wire holders 55 fixed to both ends of the center shaft 54, and two first heat generations supported by both holders 55. A body (heat generating body) 56 and a restricting arm 75 that is fixed to the center of the left and right sides of the central shaft 54 and restricts the deflection of the heat generating line are formed. The entire cutting unit 37 can be driven to rotate by the rotational power of a motor 76 housed inside the thermal cutting head 36. For this purpose, both ends of the central shaft 54 are rotatably supported by the left and right walls of the thermal cutting head 36, and a gear train 77 is provided between the motor 76 and the central shaft 54.

  The heat ray holder 55 is formed by extending support arms 78 and 79 in a cross shape from a ring portion fixed to the central shaft 54, and the first heating element 56 is formed by one of the support arms 78 sandwiching the ring portion therebetween. The raised body 80 which raises the body hair is supported by each of the other support arms 79. The support arms 78 that support the first heating element 56 are attached in directions away from each other, and themselves serve as a tension body for tensioning the first heating element 56. Therefore, the tension springs 63 and 64 in the first embodiment can be omitted.

  One first heating element 56 is connected to a pair of left and right contact terminals 60, and the other first heating element 56 is connected to a pair of left and right contact terminals 61. Therefore, when the cutting unit 37 is rotationally driven by motor power, the energization state of the first heating element 56 is mechanically turned on / off, and a driving current is alternately supplied to each first heating element 56. be able to.

  The raised body 80 is made of a strip material having a three-finger cross section formed of rubber or soft plastic having a large frictional force. As shown in FIG. 16, the restricting arm 75 is disposed on the upper side in the rotation direction of the first heating element 56 and restricts the first heating element 56 from being bent toward the upper side in the rotation direction. The restricting arm 75 is basically formed in a belt shape, but the entire arm is hardly elastically deformed by twisting the midway portion around the radial axis.

  The thermal cutting head 36 includes a lower case 81 that houses a motor 76 and an upper case 82 that is fixed to the lower case 81. The upper case 82 is integrally formed with the bristle body 50, and the front and rear ends thereof protrude in the front-rear direction from the front and rear walls of the lower case 81. The entire thermal cutting head 36 is guided and supported by the head frame 10 so as to be slidable up and down (reciprocating), and is float-supported by a float spring 51 disposed between the two 10 and 36. The human body detection sensor 68 includes a pair of left and right grip electrodes 84 provided on the grip portion of the main body case 1 and a pair of left and right skin electrodes 85 disposed on the upper end of the thermal cutting head 36. In the state where the hand is in contact with the grip electrode 84 and the skin electrode 85 is in contact with the skin surface, a driving current is supplied to the first heating element 56 to perform thermal cutting.

  18 shows the relationship between the control circuit 71, the switch 7 and the human body detection sensor 68, the relationship between the control circuit 71 and the load devices such as the motors 6 and 76, the first heating element 56, and the control circuit 71 and the energization indicator lamp. 9 shows an outline of the relationship with N.9. Hereinafter, details of the driving state of each load device and each display by the control circuit 71 will be described based on the timing chart of FIG.

  At the same time when the push button 8 is pushed and the main switch 7 is turned on, the motor 6 for the main blade 20 is started and at the same time the energization indicator lamp 9 is turned on. In this state, when the user applies the furrow body 50 to the skin surface, the grip electrode 84 and the skin electrode 85 are conducted through the human body, so the control circuit 71 activates the motor 76 for the cutting unit 37, A drive current is supplied to the first heating element 56 after the predetermined time T1 has elapsed. At this time, since the driving current is intermittently supplied to the first heating element 56, the power consumption in the thermal cutting unit 15 compared to the case where the driving current is continuously supplied to the pair of first heating elements 56. The amount can be reduced. In addition, after the motor 76 for the cutting unit 37 is activated and a predetermined time T1 has elapsed, a driving current is supplied to the first heating element 56, so that the first heating element 56 receiving wind while rotating. Can be generated, and the temperature of the first heating element 56 can be prevented from rapidly rising.

  As described above, in the case of the cutting unit 37 that performs thermal cutting while being rotationally driven, the temperature of the first heating element 56 during use is set to the same temperature as the first heating element of the cutting unit that is not rotationally driven. Therefore, the heating temperature of the first heating element 56 is set high. Therefore, when the driving current is supplied to the first heating element 56 at the same time as starting the motor 76 for the cutting unit 37 or prior to starting the motor 76, the first heating element 56 is heated more than necessary, The intensity of heat rays is extremely reduced. In order to eliminate such problems and prevent the thermal cutting from being performed in a state where the intensity of the heat ray is reduced, the first heating element 56 is caused to generate heat after the motor 76 is started and a predetermined time T1 has elapsed.

  Even if either one of the grip electrode 84 and the skin electrode 85 is separated from the hand or the skin surface, the motor 76 is continuously driven to keep the first heating element 56 in a heat generation state until a predetermined time T2 elapses. . However, the driving current value supplied to the first heating element 56 is reduced to generate heat while suppressing power consumption. This prevents the motor 76 and the first heating element 56 from being stopped every time the skin electrode 85 moves away from the skin surface, and the load when the motor 76 and the first heating element 56 are restarted. This is to alleviate the problem. After the predetermined time T2 has elapsed, the energization of the motor 76 and the first heating element 56 is stopped. When the grip electrode 84 and the skin electrode 85 are conducted through the human body again, the energization of the first heating element 56 and the motor 76 is resumed. Finally, when the push button 8 is pushed in and the main switch 7 is switched to the OFF state, the supply of current to all members is stopped. Since it is the same as that of the hair treatment apparatus of Example 1 except the above, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

  As described above, according to the hair processing apparatus that performs thermal cutting while rotationally driving the cutting unit 37, each first heating element 56 is separated from the skin surface at the same time as cutting the beard and hair, so the first heating element It is possible to more reliably prevent the skin surface from feeling hot with the heat of 56. Further, since thermal cutting is performed while intermittently supplying a drive current to the pair of first heating elements 56, hair can be thermally cut while preventing the heating temperature of the first heating element 56 from becoming unnecessarily high. The thermal cutting of the beard and body hair by the body hair treatment device can be performed comfortably.

The hair processing apparatus according to the second embodiment can be implemented in the following form.
1) A furrow body 50 is provided on the outer surface of the thermal cutting head 36 to scrub the hair, and a cutting unit 37 provided with a heating element 56 inside the thermal cutting head 36 and a motor 76 for rotating the cutting unit 37 are arranged.

3) The energized state of the heating element 56 is intermittently turned on and off to thermally cut the hair.
4) Fix the contact terminals 60 and 61 to the peripheral surface of the shaft end of the central shaft 54. A fixed terminal 62 is provided on the outer peripheral surface of the central shaft 54 to supply a driving current to the heating element 56 in sliding contact with the contact terminals 60 and 61. As the cutting unit 37 rotates, the energization state of the heating element 56 is mechanically turned on / off.
5) The main body case 1 and / or the hair processing head 2 is provided with a human body detection sensor 68 that detects that the thermal cutting head 36 has come into contact with the human body. In a state where the human body detection sensor 68 detects that the human body is in contact with the human body, the driving current is supplied to the heating element 56.

  FIG. 20 is a timing chart showing details of driving states of each load device and each display device by the control circuit 71 when the human body detection sensor 68 in the second embodiment is omitted. In that case, at the same time as the main switch 7 is turned on, the motor 6 for the main blade 20 and the motor 76 for the cutting unit 37 are activated, and at the same time, the energization indicator lamp 9 is turned on. Then, after the predetermined time T1 has elapsed, a drive current is supplied to the first heating element 56 to cause the first heating element 56 receiving the wind while rotating to generate heat, similarly to the second embodiment. The temperature of the first heating element 56 is prevented from rising rapidly.

  Further, until the predetermined time T2 has elapsed after the main switch 7 is switched to the OFF state, the motor 76 is continuously driven to keep the first heating element 56 in the heat generation state. However, the driving current value supplied to the first heating element 56 is reduced to generate heat while suppressing power consumption. This prevents the motor 76 and the first heating element 56 from being stopped every time the main switch 7 is turned on and off, and the load when the motor 76 and the first heating element 56 are restarted is prevented. This is to alleviate.

The hair processing apparatus described in Example 2 and FIG. 20 can be implemented in the following form.
1) After the motor 76 for the cutting unit 37 is activated, a drive current is supplied to the heating element 56 after a predetermined time T1 has elapsed.
2) After the main switch 7 and the human body detection sensor 68 are switched to the OFF state, the energized state of the motor 76 for the cutting unit 37 and the first heating element 56 is continuously maintained until a predetermined time T2 elapses. .
3) The driving current supplied to the first heating element 56 during the predetermined time T2 is set to be smaller than the driving current supplied to the first heating element 56 in the use state, and the consumption of the first heating element 56 Heat is generated with the power suppressed.

  According to the first embodiment, the driving current is supplied to the first heating element 56 after the motor 76 for the cutting unit 37 is activated and the predetermined time T1 has elapsed. Therefore, the first heating element 56 receiving the heat can be caused to generate heat, and thus the temperature of the first heating element 56 is prevented from rapidly rising. Moreover, it can eliminate that the 1st heat generating body 56 is heated more than needed, the intensity | strength of a heat ray falls extremely, and it can prevent that a thermal cutting is performed in the state where the intensity | strength of a heat ray fell.

  According to the second embodiment, when the human body detection sensor 68 is switched to the off state, the energization of the motor 76 for the cutting unit 37 and the first heating element 56 is continued until the predetermined time T2 elapses. Continue to maintain state. Therefore, every time the human body detection sensor 68 is switched to the OFF state, the driving of the motor 76 and the first heating element 56 is prevented from being stopped, and the motor 76 and the first heating element 56 are restarted. The load can be reduced.

  According to the above embodiment 3), after the human body detection sensor 68 is switched to the OFF state, the heat generation state is performed while the predetermined time T2 elapses, that is, while the power consumption of the first heating element 56 in the standby state is suppressed. Can be maintained. Moreover, since the load when the motor 76 and the 1st heat generating body 56 are restarted can be reduced, the exhaustion degree of the battery 3 can be reduced as a whole.

A raised body 80 is arranged on the opposing peripheral surface of the holder 55. The human body detection sensor 68 is configured by a non-contact ultrasonic proximity sensor, and the cutting unit 37 comes into contact with the skin surface from the time until the emitted ultrasonic wave is reflected by the skin surface and returned. It is determined whether or not. Since others are the same as the hair processing apparatus of Example 1 and Example 2, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.
