A connected RAM, 16 is a ROM similarly connected to the CPU 15, and 17 is an EEPROM connected to the CPU.
[0018]
Next, the operation will be described based on the above configuration.
First, various modes, which are standard operating conditions, are stored in the ROM 15 at the time of shipment from the factory. When a subject performs a treatment under general operating conditions, the operator can select and operate the operation switch 13 to perform the treatment. it can.
[0019]
Here, if it is determined from the contents of various treatments and the nature of the hair of the subject that the treatment cannot be performed in the preset mode, the operation shown in the flowchart of FIG. Register and store.
[0020]
First, the power of the hair treatment accelerating device is turned on (step S1), and the operation switch 13 is operated to select a mode of the operating condition that is considered to be the most suitable from the modes stored in advance (step S2). . Next, in the selected mode, the temperature level to be set, the heating time, and in the case of a swing operation, the swing angle are changed by the operation switch 13 in accordance with the treatment contents of the subject and the properties of the medicine and the hair (step). S3).
[0021]
Then, the practitioner determines whether or not to store the data in the memory under the set conditions (step S4). If the practitioner determines to store the data in the EEPROM 17, the mode switch of the operation switch 13 is continuously pressed for a predetermined time or longer. (Step S5) When the setting mode is stored in the RAM 15, the buzzer sounds and informs that the setting has been stored (Step S6), and the operating conditions desired by the practitioner are stored.
[0022]
Therefore, it is possible to perform the treatment under the optimal condition by selecting the optimal operation condition from the many operation conditions stored in the EEPROM 17 according to the treatment content at the time of the treatment of the subject and the medicine to be used and performing the treatment. This makes it possible for the operator to perform no complicated setting work.
[0023]
Next, a case where the camera is tilted or falls over for some reason will be described.
Now, for example, when the hair processing accelerating device is tilted by the tilt sensor 11a beyond a preset angle, the tilt sensor 11a detects the tilt and outputs a signal to the CPU 14, so that the CPU 14 Cut off the power supply to.
[0024]
Thus, even if the hair treatment accelerating device falls, even if the power supply to the motor 3 and the heater 73 is cut off, a fire may occur, or the operator may touch the device to raise the device. Also, no injury is caused because the case 71 is stopped.
[0025]
Next, an operation in a case where the heating device 7 is rotated or stopped, and not only rotation in one direction but also rotation inversion at a constant cycle will be described.
Conventionally, only the energization and cutoff of the motor 3 is controlled by a command from the CPU. However, in this embodiment, when the motor 3 is started and the rotation direction is reversed (hereinafter referred to as swing), the motor 3 is started. A plurality of cycles in the waveform of the AC power supply to be applied to, and a subsequent half cycle or a cycle shorter than the plurality of cycles is repeated a plurality of times of the energizing method of shutting off energization, thereby suppressing the shock at the time of starting and stopping, thereby suppressing The vibration of the arm 7 attached to the ceiling and the heating device 7 attached to the column 1 can be prevented.
[0026]
That is, as shown in FIG. 4, the operation of energizing the motor 3 for two cycles of the power frequency at the time of initial power-on or reversal, and interrupting the energization of the motor 3 for the subsequent half cycle is repeated 10 times. 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.
[0027]
Note that, as another control method, the CPU 14 can control a switch for connecting / disconnecting a resistor connected in series to the motor 3 by a start start switch or a swing start command signal. That is, by connecting the resistor and the motor 3 in series for 0.3 seconds at the time of starting, the voltage applied to the motor 3 is reduced, the starting torque is reduced, and the starting shock can be reduced.
[0028]
Since this embodiment includes the non-contact thermometer 8 and the visible light emitting device 9, first, the light source 9a of the visible light emitting device 9 is turned on and the light converged by the lens 9b. Is set at the center of the occipital region of the subject, that is, the position where the non-contact thermometer 8 measures the temperature of the hair.
[0029]
Then, by energizing the heater 73 and energizing the motor 3, the heater 73 heats at a constant temperature while rotating the entire head of the subject, so that hair treatment is promoted, and hair washing is dried and dyed. It can promote and promote permanent hair satisfactorily.
[0030]
In this way, the temperature of the hair of the subject is measured by the non-contact thermometer 8 and the temperature is adjusted. At this time, if the non-contact thermometer 8 fails, the heater 73 is continuously energized. The temperature will be abnormally high. Therefore, in the present embodiment, if the temperature does not reach the preset temperature even after the elapse of a certain time, that is, if the non-contact thermometer 8 is out of order, the set temperature is not detected. The output of the total 8 outputs a signal of a low value to the CPU 14.
[0031]
Therefore, the CPU 14 monitors the signal from the non-contact thermometer 8 with respect to the set time, and when the signal from the non-contact thermometer 8 is small, turns on / off the energization of the heater 73 to prevent abnormal heat generation. The operation is performed so as to secure the safety of the hair of the subject due to abnormal heating by interrupting the power supply to the heater 73.
[0032]
When such an abnormality occurs, the approximate temperature of the person near the non-contact thermometer 8 whose approximate temperature is known in advance, for example, the palm of a person is approached, and the non-contact thermometer at this time By displaying several times the temperature detected by the CPU 8 via the CPU 14, it can be determined whether or not the non-contact thermometer 8 is abnormal. Therefore, in such a case, only the non-contact thermometer 8 is used. By performing the replacement, repair can be performed, and waste such as replacing the control board 11 as in the related art can be prevented.
[0033]
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 fixed home position, the heating device 7 can be reciprocatedly rotated (swinged) at a fixed rotation angle, and the non-contact thermometer 8 The temperature can be taken in a position not obstructed by the heating device 7.
[0034]
First, the operation of stopping the rotating heating device 7 at the home position will be described.
When the operator performs a stop operation by the operation switch 13 or when a stop command is transmitted from the CPU 14 after reaching a time according to a preset operation condition mode, the photocoupler 12 b firstly stops the narrow slit 12 of the disk 12. 12a ₂ (for clockwise rotation) or a narrow stop slit 12a ₃ (for counterclockwise rotation). CPU14 that has received the detection signal, for example, by turning off the power to the motor 3 is judged to be the home position is reached slits 12a ₁ within 0.5 seconds, the heating device 7 at the home position It will stop.
[0035]
Incidentally, in the product of this embodiment, 10-degree rotation (0.5 seconds) from the detection of the slit 12a ₂ or slit 12a ₃ Then reached slit 12a _1, and stops at the home position.
[0036]
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, that is, the number of rotations and the number of rotations, The elapsed time after passing the home position is monitored by the CPU 14, and after this time has elapsed, the swing operation can be performed by reversing the direction of energization to the motor 3. The reversal angle of this swing is up to 90 degrees and the minimum is 20 degrees.
[0037]
The non-contact thermometer 8 always measures the hair temperature at a predetermined position of the subject, but the temperature measurement by the contact thermometer 8 measures the temperature of the cover 71 because the heating device 7 is rotating. The 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 reflection plate 72. Therefore, if the temperature from the contacted thermometer 8 is always taken in, it will be higher than the hair temperature as an average value.
[0038]
Therefore, in the present embodiment, when the measurement by the contact thermometer 8 for sensing the slits _{12a 4, 12a 5, 12a 6} signal CPU14 that photocoupler 12b detects the passage position without the cover 71 has received The data from the contacted thermometer 8 is taken and adopted as data for controlling the temperature of the heater 73. Thereby, the temperature control of the heater 73 can accurately follow the preset value.
[0039]
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 the data is held by the backup battery when the power is turned off. You may.
[0040]
