Electronic components include storage components such as EEPROM and RAM, microcomputers, and the like. The storage component stores a computer program for performing various drying courses for hair drying, and stores various parameters and the like used for executing the computer program. The parameters include, for example, the ventilation conditions of the tables T1 and T2 in FIG. The microcomputer controls the blower unit 2 and the heating unit 3 in response to various drying courses by executing a computer program stored in the storage component.

The control unit 7 controls the blower unit 2 and the heating unit 3 according to the operation of the cool button 16 and the main switch 53 of the user.
When the cool button 16 is turned on by the user, the control unit 7 gives priority to the execution of the cool course described later even while the drying course selected by the main switch 53 is being executed. It should be noted that executing the cool course is also referred to as cool operation, and executing the drying course selected by the main switch 53 is also referred to as main operation.
When the main switch 53 is operated by the user, the control unit 7 performs the selected main operation. An example of the main operation here is three types of operation, which will be described later: cool operation, set operation, and turbo operation.
The control unit 7 executes the heat eye course when the heat eye switch 55 is turned on, that is, enabled by the user. When the heat eye switch 55 is turned on during the main operation, the control unit 7 preferentially executes the heat eye course. When the cool button 16 is turned on during the heat eye course, the control unit 7 preferentially executes the cool course. The execution of the heat eye course is also referred to as heat eye operation.

The heat eye course is one of the drying courses according to the hair temperature of the hair drying target measured by the temperature measuring unit 4, and the control unit 7 sets the blowing conditions according to the hair temperature measured by the temperature measuring unit 4. Control. Specifically, the heat eye operation is a high-temperature strong wind operation in which a high-temperature wind is blown by a strong wind until the hair temperature reaches a predetermined first temperature (T1), and a medium-temperature wind is blown when the hair temperature reaches a predetermined first temperature (T1). It includes at least a medium-temperature medium-air operation in which a medium-temperature air is blown, and a low-temperature strong wind operation in which a low-temperature wind is blown by a strong wind at a predetermined second temperature (T2) lower than the predetermined first temperature (T1).
In other words, the heat eye operation initially operates at a high temperature and strong wind, and when the hair temperature reaches a predetermined first temperature (T1), it switches to a medium temperature medium wind operation, and the hair temperature drops to a predetermined second temperature (T2). It is a control to switch to low temperature and strong wind operation. As a result, damage to the hair to be dried can be suppressed. It should be noted that the damage suppressing effect is enhanced by performing the above-mentioned three operations of high temperature strong wind operation, medium temperature medium wind operation, and low temperature strong wind operation. Further, it is also possible to automatically dry the hair according to the hair temperature by continuously performing the high temperature strong wind operation, the medium temperature medium wind operation, and the low temperature strong wind operation.
The ventilation conditions are the ventilation temperature and the ventilation volume. Here, the control of the air volume of the blower unit 2 and the temperature of the heating unit 3 outputs the parameters of the air volume and temperature corresponding to the drying course to the power supply unit 8, and the power supply unit 8 outputs the parameters of the air volume and temperature corresponding to the drying course to the power supply unit 8 based on the parameters, for example, by PWM control or the like. The electric power of the air volume and temperature corresponding to the above is supplied to the blower unit 2 and the heating unit 3.
In the case of the heat eye course, the control unit 7 causes the LED 181 to emit light with a light color corresponding to the measured hair temperature. Here, the control unit 7 generates a current corresponding to the drying course by, for example, PWM control, and supplies it to each LED 181.

(2) Control of each course (2-1) Main operation (S6)
As shown in the table T1 shown in FIG. 10A, for example, there are three types of main operation: cool operation, set operation, and turbo operation. The cool operation by turning on the cool button 16 has the same conditions as the cool operation in the main operation, and the description thereof will be omitted.
In the cool operation, the heater 31 is at low temperature (on) and the drive motor 21 is at medium wind (low temperature medium wind operation). In the set operation, the heater 31 is at medium temperature (ON) and the drive motor 21 is at low wind (medium temperature and weak wind operation). In turbo operation, the heater 31 is at medium temperature (on) and the drive motor 21 is at strong wind (medium temperature strong wind operation).
The air volume is controlled by the electric power supplied to the drive motor 21 as the drive motor 21 becomes stronger in the order of weak wind, medium wind, and strong wind. The temperature increases in the order of low temperature, medium temperature, and high temperature, and is controlled by the electric power supplied to the heater 31.

The main operation will be described with reference to FIG.
When the selection of cool operation, set operation or turbo operation is input from the main switch 53, the control unit 7 reads out the conditions of the corresponding operation heater 31 and drive motor 21 from the table T1 shown in FIG. 10 and performs operation. Carry out (S61). Specifically, the power supply unit 8 is instructed to operate under the read conditions, and the power supply unit 8 supplies the electric power under the instructed conditions to the blower unit 2 and the heating unit 3.

In step S62, when the cool button 16 is turned on, the conditions of the heater 31 and the drive motor 21 for the cool operation are read from the table T1 shown in FIG. 10, and the cool operation is performed until the cool button 16 is turned off (in S62).

In step S65, when the heat eye is valid (“Yes”), after the heat eye operation is executed (S66), if the main switch 53 is not turned off (“No” in S67), the process returns to step S61. The operation of the selected drying course is performed, and when the main switch 53 is turned off (“Yes” in S67), the process returns to the main routine.

(2-2) Heat eye operation (S7, S66)
The heat eye operation in step S7 (see FIG. 9) of the main routine and the heat eye operation in step S66 (see FIG. 11) in the main operation (S6) are basically the same flowchart, and here, the heat eye operation in step S7. Will be explained.
For example, as shown in the table T2 of FIG. 10B, the heat eye operation automatically performs three operations of high temperature strong wind operation, medium temperature medium wind operation, and low temperature strong wind operation.
The high-temperature strong wind operation is for drying the hair at an early stage. The heater 31 is on (high temperature), the drive motor 21 is strong wind, and the emission color of the notification unit 18 is red.
In the medium-temperature and medium-air operation, the hair is dried while suppressing damage to the hair. The heater 31 is on (medium temperature), the drive motor 21 is medium-air, and the emission color of the notification unit 18 is orange.
The low temperature strong wind operation is for drying the hair only with air, the heater 31 is off (low temperature), the drive motor 21 is strong wind, and the emission color of the notification unit 18 is blue.

The control unit 7 during the heat eye operation will be described with reference to FIG.
When the heat eye operation (S7) starts, the control unit 7 reads out the conditions of the corresponding heater 31 and the drive motor 21 and the emission color of the LED 181 from the table T2 shown in FIG. 10 (b), and executes the high temperature strong wind operation ( S70). More specifically, the power supply unit 8 is instructed to operate under the read conditions, and the power supply unit 8 supplies the electric power under the instructed conditions to the blower unit 2 and the heating unit 3. The control unit 7 supplies the LED 181.

In step S71, it is determined whether the hair temperature T measured by the temperature measuring unit 4 is equal to or higher than the first temperature T1, and if the hair temperature T is less than the first temperature T1 (“No”), the user determines. It is determined whether or not the heat eye is invalidated (S72).
If it is disabled (“Yes”), it returns to S1 of the main routine to stop the heat eye operation, and if it is not disabled (“No”), step S71 while continuing the high temperature strong wind operation. Proceed to.
In step S71, if the hair temperature T is equal to or higher than the first temperature T1 (“Yes”), the conditions of the corresponding heater 31 and the drive motor 21 and the emission color of the LED 181 are read from the table T2, and the medium temperature medium wind operation is performed. Then (S73), the process proceeds to step S74.

In step S74, it is determined whether the hair temperature T measured by the temperature measuring unit 4 is equal to or higher than the second temperature T2, and if the hair temperature T is less than the second temperature T2 (“No”), the user determines. It is determined whether or not the heat eye is invalidated (S75).
If it is disabled (“Yes”), it returns to S1 of the main routine to stop the heat eye operation, and if it is not disabled (“No”), step S74 while continuing the medium temperature and medium wind operation. Proceed to.
In step S74, if the hair temperature T is the second temperature T2 or higher (“Yes”), the conditions of the corresponding heater 31 and the drive motor 21 and the emission color of the LED 181 are read from the table T2, and the low temperature strong wind operation is performed. Then (S76), the process proceeds to step S77.

In step S77, it is determined whether the hair temperature T measured by the temperature measuring unit 4 is the third temperature T3 or less, and when the hair temperature T is higher than the third temperature T3 (“No”), the heat eye is determined by the user. Is determined whether or not has been invalidated (S78).
If it is disabled (“Yes”), it returns to S1 of the main routine to stop the heat eye operation, and if it is not disabled (“No”), step S77 while continuing the low temperature and strong wind operation. Proceed to.
In step S77, if the hair temperature T is equal to or lower than the third temperature T3 (“Yes”), all the steps of the heat eye operation are completed, and the process proceeds to step S1 of the main routine.
In the case of the heat eye operation in step S66, when the heat eye is disabled in steps S72, S75, and S78 in FIG. 12, the process proceeds to step S67 instead of step S1.
As an example, the first temperature T1 is 36 degrees, the second temperature T2 is 40 degrees, and the third temperature T3 is 31 degrees, but they are appropriately changed according to the performance of the blower unit 2 and the heating unit 3. You may.

5. Position of the temperature measuring unit The position of the temperature measuring unit 4 will be described with reference to FIG. In the figure, (a) is a state in which an attachment is not attached, and (b) is a state in which an attachment is attached.

In particular, when the dryer is in use (the handle is stretched in the vertical direction and is also called an open state) and the dryer is in a bent state (the handle is stretched in the front-rear direction and is also called a closed state), the handle is the dryer body. A dryer having a structure for restricting rotation with respect to a ring (for example, Japanese Patent Application Laid-Open No. 60-19857) has been proposed, but the structure has the following problems.
That is, since the rotation is regulated by the load applied by the ring to the peripheral edge portion when the handle is rotated, there is a problem that cracks occur in the peripheral edge portion when the load is large and the rotation cannot be regulated when the load is small. In order to solve this problem, for example, thickening the peripheral portion causes another problem such as sink marks on the handle. If the peripheral edge is thinned so that sink marks do not appear, cracks will occur.
