The connected RAM, 16 is also a ROM connected to the CPU 15, and 17 is an EEPROM connected to the CPU.
[0017]
Next, the operation will be described based on the above-described configuration.
First, various modes, which are standard operating conditions, are stored in the ROM 15 at the time of shipment from the factory. When the patient performs a procedure under general operating conditions, the operation switch 13 can be selected to perform the procedure. it can.
[0018]
Here, when it is determined that the treatment cannot be performed in the preset mode from the contents of various treatments and the properties of the hair of the person to be treated, the operation shown in the flowchart of FIG. Remember me registered.
[0019]
First, the power of the hair treatment promoting device is turned on (step S1), and the operation switch 13 is operated to select the mode of the driving condition that seems to be most suitable among the modes stored in advance (step S2). . Next, in the case of the temperature level desired to be set in the selected mode, the heating time, and the swing operation, the swing angle is changed by the operation switch 13 according to the treatment contents of the patient and the nature of the medicine and hair (step) S3).
[0020]
Then, the practitioner determines whether or not he / she wants to store in the memory under the set condition (step S4). When he / she determines to store in the EEPROM 17, the mode switch in the operation switch 13 is continuously pressed for a predetermined time or more. (Step S5) When the setting mode is stored in the RAM 15, the buzzer sounds to notify that it has been stored (Step S6), and the operating conditions desired by the operator are stored in memory.
[0021]
Therefore, the treatment can be performed under the optimum conditions by selecting the optimum operation condition from the many operation conditions stored in the EEPROM 17 according to the treatment contents and the medicine to be used at the time of the treatment of the person to be treated. In addition, it is not necessary to perform troublesome setting work for the practitioner.
[0022]
Next, a case where the robot tilts or falls for some reason will be described.
Now, for example, when the hair treatment promoting device is tilted more than the angle preset by the tilt sensor 11a, the tilt sensor 11a detects that the tilt sensor 11a is tilted and outputs a signal to the CPU 14. Therefore, the CPU 14 outputs the motor 3 and the heater 73. Shut off the power to the.
[0023]
As a result, even if the hair treatment promoting device falls down, the energization of the motor 3 and the heater 73 is interrupted, so that a fire occurs or the practitioner touches the device to stand the device. However, since the case 71 is stopped, there is no risk of injury.
[0024]
Next, the operation in the case of rotating the heating device 7 or stopping the rotation and reversing the rotation not only in one direction but also at a constant period will be described.
Conventionally, only the energization and shut-off of the motor 3 are controlled by a command from the CPU. In this embodiment, the motor 3 is activated at the time of starting the motor 3 and reversing the rotation direction (hereinafter referred to as swing). The shock at the start and stop is suppressed by repeating the energization method such as energizing a plurality of cycles in the waveform of the AC power supply applied to the power supply and then shutting off the energization in the subsequent half cycle or less than the plurality of cycles. The vibration of the arm attached to the ceiling and the heating device 7 attached to the column 1 can be prevented.
[0025]
That is, as shown in FIG. 4, by repeating the operation of energizing the motor 3 for 2 cycles of the power frequency at the time of initial power-on or reversal, and interrupting the energization of the motor 3 in the subsequent half cycle, The motor 3 rotates slowly during the control from the start of the start up to the ten times, so that the shock at the start is reduced.
[0026]
As another control method, the CPU 14 can control the start switch or the switch for connecting / disconnecting the resistor connected in series to the motor 3 by the swing start command signal. That is, by connecting the resistor and the motor 3 in series for 0.3 seconds after starting, the voltage applied to the motor 3 can be lowered to reduce the starting torque, thereby reducing the starting shock.
[0027]
In this embodiment, since the non-contact thermometer 8 and the visible light emitting device 9 are provided, first, the light 9a of the visible light emitting device 9 is turned on and the light converged by the lens 9b. Are set so that the center of the back of the subject's head, that is, the position at which the non-contact thermometer 8 measures the temperature of the hair.
[0028]
Then, by energizing the heater 73 and energizing the motor 3, the heater 73 heats the entire head of the person to be heated at a constant temperature, so that the hair treatment is promoted and the hair washing is dried and dyed. Promotes and promotes a permanent wave of hair.
[0029]
In this way, the temperature of the subject's hair is measured by the non-contact thermometer 8 to adjust the temperature. At this time, if the non-contact thermometer 8 fails, the heater 73 is continuously energized. Will become abnormally hot. Therefore, in the present embodiment, when the preset temperature is not reached even after a certain time has elapsed, that is, when the non-contact thermometer 8 is out of order, the set temperature is not detected. The output of the total 8 outputs a low value signal to the CPU 14.
[0030]
Therefore, the CPU 14 monitors the signal from the non-contact thermometer 8 for the set time, and when the signal from the non-contact thermometer 8 is small, the heater 73 is turned on / off to prevent abnormal heat generation. It controls so that it may perform, or it cuts off electricity supply to heater 73, and operates so that the safety to the hair of the person to be treated by abnormal heating may be secured.
[0031]
Further, when such an abnormality occurs, the approximate temperature that is known in advance in front of the non-contact thermometer 8 is known, for example, a person's palm is brought close, and the non-contact thermometer at this time It is possible to determine whether or not the non-contact thermometer 8 is abnormal by displaying the number of times detected by the CPU 8 via the CPU 14. Therefore, in such a case, only the non-contact thermometer 8 is detected. It can be repaired by exchanging, and waste such as exchanging the conventional control board 11 can be prevented.
[0032]
In the present embodiment, the slits _12a 1 ~12a ₆ disc 12 is formed as shown in FIG. 5 is rotated in synchronism with the rotation of the motor 3, the slit 12a1 ~12a ₆ in photocoupler 12b By detecting, the heating device 7 can always be stopped at a constant home position, and the heating device 7 can be reciprocated (swinged) at a constant rotation angle. The temperature can be taken in a position that is not obstructed by the heating device 7.
[0033]
First, the operation of stopping the rotating heating device 7 at the home position will be described.
When the practitioner performs a stop operation with the operation switch 13 or when a stop command is sent from the CPU 14 when the time in the preset operating condition mode is reached, the photocoupler 12b first has a narrow stop slit for the disc 12. 12a ₂ (for clockwise rotation) or narrow stop slit 12a ₃ (for counterclockwise rotation) is detected. Upon receiving this detection signal, for example, when the CPU 14 reaches the slit 12a ₁ within 0.5 seconds, the CPU 14 determines that the position is at the home position and cuts off the power supply to the motor 3, whereby the heating device 7 is at the home position. Will stop.
[0034]
In the product according to the present embodiment, when the slit 12a ₂ or the slit 12a ₃ is detected and then rotated 10 degrees (0.5 seconds), it reaches the slit 12a ₁ and stops at the home position.
[0035]
Next, the operation of swinging the heating device 7 will be described. Since the heating device 7 always detects the home position as described above, the swing angle, i.e., how many times it is rotated, is reversed. The elapsed time after passing through the home position is monitored by the CPU 14, and the swing operation can be performed by reversing the direction of energization to the motor 3 after this time has elapsed. The inversion angle of this swing is up to 90 degrees and the minimum is 20 degrees.
[0036]
The non-contact thermometer 8 always measures the hair temperature at a predetermined position of the person to be treated. However, the temperature measurement by the contact thermometer 8 is the temperature of the cover 71 because the heating device 7 is rotating. Measurement is performed twice in one rotation of the heating device 7. The temperature of the cover 71 is higher than the temperature of the hair because the temperature of the heater 73 is heated via the reflector 72. Therefore, if the temperature from the contact thermometer 8 is always taken in, the average value is higher than the hair temperature.
[0037]
Therefore, in the present embodiment, when the CPU 14 receives a signal detected by the photocoupler 12b of the sensing slits 12a ₄ , 12a ₅ , 12a ₆ at a position where the measurement by the contacted thermometer 8 does not pass through the cover 71. The data from the contact thermometer 8 was taken in and used as data for temperature control of the heater 73. Thereby, the temperature control of the heater 73 can be accurately followed with respect to a preset value.
[0038]
Although the case where the nonvolatile EEPROM 17 is used as the memory in the above-described embodiment has been described, a volatile memory is used as the other memory, and data retention during a power failure is performed by a backup battery. Also good.
[0039]
【The invention's effect】
As described above, the present invention includes a home position slit on a disk rotating in conjunction with a motor for rotating a heating device including a heater and a reflector, and a stop slit located on both sides of the slit. The heating device is stopped at the home position by shutting off the energization to the motor when the home position slit is detected within a predetermined time after detecting the stop slit in the rotation direction of the heating device. Therefore, even if the heating device is reciprocally rotated, it can be stopped accurately at the home position, and the sliding of the rotating parts such as the motor gear and the rotating power feeding device can be prevented.
[0040]
In addition, the user's hair can be partially heated and the reciprocating rotation angle can be reciprocated between a desired angle and a desired revolving angle. It has the effect of corresponding.
