Description

The present invention relates to a perm device, an abnormality display method thereof, an abnormality display system thereof, an abnormality display program thereof, a recording medium of the abnormality display program, and a server recording the abnormality display program.

At the hairdressing shop, a perm device is placed near the person to be treated sitting on a chair in the hairdressing shop, who receives the perm treatment from the practitioner, and the perm treatment is performed.
Specifically, in the perm device, an electric heating rod is connected to the main body portion via an electric cord, and the electric heating rod is provided with a heater that receives electricity from the main body portion through the cable and generates heat. .. Then, by wrapping the hair of the person to be treated around the electric heating rod to generate heat of the heater, it is possible to perform deformation processing such as wave formation on the hair (Patent Documents 1 to 3).

In particular, Patent Document 1 has a circuit breaking means, in which the temperature sensed by the inner sensor (8) is set in advance regardless of the temperature sensed by the outer sensor (5). A perm device that operates to limit the energization of the heat generating member (2) when the temperature exceeds the above is shown (claim 1). In Patent Document 1, as an effect of the invention, it is possible to provide a perm device capable of appropriately controlling the temperature of the electric heating rod 1, preventing abnormal overheating leading to burning of the heat generating member 2, and being able to be used safely. In addition, unlike the conventional control using a dummy electric heating rod, the sensor rod 1b actually measures the temperature of the tubular member 11 around which the hair is wound, so that highly accurate control can be performed. ing.

Further, in Patent Document 2, the control unit (63) receives the temperature signal emitted by the sensor (5) of the sensor rod (1b) and issues an on / off command to the switching element (64). (64) is a controlled rod group in which a plurality of dedicated heating rods (1a) are combined with one sensor rod (1b) by turning on / off the current of the electric heating rod (1) to the heat generating member (2). For each (X), the on / off control of the heat generating member (2) of each electric heating rod (1) is performed by the control unit (63), and the control unit (63) is at least one. When the temperature signal sent from the sensor (5) to the control unit (63) becomes unreceivable, the fault handling means (Xt) that operates to control the fault controlled rod group (Xt) to which the sensor (5) belongs ( A perm device comprising 63a) is shown (claim 1).

In Patent Document 2, as an effect of the invention, by providing the sensor 5 for measuring the temperature of the outer peripheral surface 11 on the sensor rod 1b of the electric heating rod 1, overheating of the electric heating rod 1 can be prevented and it is safe. Unlike the control by the conventional dummy electric heating rod, the sensor rod 1b actually measures the temperature of the outer peripheral surface 11 around which the hair is wound, so that highly accurate control can be performed, and a plurality of sensors can be used. The electric heating rod 1 is divided into controlled rod group X, and the temperature can be adjusted for each controlled rod group X, so that it is easy to use and unlike the conventional uniform control, the hair is finely deformed. In addition, when the temperature signal sent from the sensor 5 to the control unit 63 becomes unreceivable, the control unit 63 operates to control the failure controlled rod group Xt to which the sensor 5 belongs. Since the means 63a is provided, it is possible to reduce the possibility that a treatment error occurs due to abnormal overheating or a temperature drop, or the entire perm device becomes inoperable.

Further, in Patent Document 3, the electric heating rod (1) detects the temperature of the heater (H) heated by energization and the electric heating rod (1), and uses an electric signal corresponding to the detected temperature. A circuit provided with a temperature detection signal response unit (42) for responding to a certain temperature detection signal (S), and transmitting a temperature detection signal (S) between the heating rod (1) and the main body unit (2). Passes through the electric cord (3) from the switch portion (46) in the main body portion (2), passes through the temperature detection signal response unit (42) in the heating rod (1), and passes through the electric cord (3) to the main body portion. It is configured to return to the switch unit (46) in (2), and the switch unit (46) switches between the heater heating current (P) and the temperature detection signal (S) at predetermined time intervals to switch the main body unit. The temperature detection signal (S) received from the temperature detection signal response unit (42) is predetermined in the signal processing unit (44), which is supplied from (2) to the electric heating rod (1). If the temperature value corresponding to the received temperature detection signal (S) is smaller than the temperature value corresponding to the set value of the temperature detection signal (S), the heater heating current (P) to the heater (H) ) Is energized, and if the temperature value corresponding to the temperature detection signal (S) is larger than the above set value, is the energization of the heater heating current (P) to the heater (H) cut off? Alternatively, the electric cord (3) can transmit the temperature detection signal (S) and supply the heater heating current (P) to the electric heating rod (1) and the main body (2). The temperature control mechanism of the electric heating rod, which is connected in such a manner and serves as both the electric wire for transmitting the temperature detection signal (S) and the electric wire for supplying the heater heating current (P), is shown (. Claim 1).

In Patent Document 3, as an effect of the invention, the signal processing unit controls the energization of the heater in response to the temperature detection signal corresponding to the detected temperature of the electric heating rod, which is responded from the temperature detection signal response unit. The temperature of the rod around which the hair is wrapped can be controlled appropriately, and multiple electric heating rods can be individually controlled. Furthermore, the temperature detection signal exchanged between the heater and the main body, or the state of the signal processing unit. It is possible to detect conduction failure due to disconnection of the heater or electric cord by using the management signal for managing the temperature, and the electric cord supplies the electric wire for transmitting the temperature detection signal and the current for heating the heater. Since it is also used as an electric wire for the electric cord, the weight of the electric cord does not increase as compared with the conventional one, and the burden on the person to be treated is not increased more than before.

(Basic configuration of perm device 100)
This perm device 100 is arranged and used in the vicinity of the person to be treated j who sits on the hairdressing chair i and receives a perm treatment on the hair from the practitioner (not shown) in the hairdressing shop (FIG. 1 (FIG. 1). A)), FIG. 2 (A).
The perm device 100 includes a plurality of electric heating rods 2, a main body portion 1, and a plurality of electric cords 3 (FIGS. 1 (A), 2 (A), and 4).

The electric heating rod 2 is connected to the main body 1 via the electric cord 3, and each of the electric heating rods 2 receives electricity from the heater 21 that generates electricity by receiving electricity from the main body 1 through the electric cord 3. In particular, it is provided with a temperature sensor 22 that detects the temperature of the electric heating rod 2. By wrapping the hair of the person to be treated around the electric heating rod 2 to generate heat of the heater 21, it is possible to perform deformation processing such as wave formation on the hair of the person to be treated. The electric heating rod 2 is provided at the tip of the electric cord 3, and a connection plug 31 is provided at the base end of the electric cord 3.

The main body 1 is an output control that operates the power supply unit 10 under the control of the power supply unit 10 that supplies electricity to the electric heating rod 2, the control unit 11 that controls the supply of electricity by the power supply unit 10, and the control unit 11. The unit 11a, the current detection unit 12 that detects the current supplied to the electric heating rod 2, the current measurement unit 12a that measures the current detected by the current detection unit 12 and sends the measured current value to the control unit, and the temperature sensor. The temperature measuring unit 13 that measures the temperature of the electric heating rod 2 detected by 22 and transmits it to the control unit 11, the display unit 14 that can display the abnormality of the energization state to the practitioner, and the operation from the practitioner. The operation unit 15 for receiving and a plurality of sockets 16 are provided.

The main body 1 also includes a detection unit for detecting the presence or absence of an abnormality in energization of the perm device 100 that deforms the hair of the person to be treated, at least when the perm device 100 is not in operation (during operation standby).
The detection unit includes a first detection unit that detects the presence or absence of an abnormality in energization of the electric heating rod 2, and a second detection unit that detects the presence or absence of an abnormality in energization of the temperature sensor 22 among the energization states of the electric heating rod 2. To prepare for.
In this example, the first detection unit is composed of the current detection unit 12 and the current measurement unit 12a, and the second detection unit is composed of the temperature sensor 22 and the temperature measurement unit 13. That is, in this example, the detecting means for detecting the current value and the temperature of the electric heating rod 2 including the energized state during operation also serves as the detection unit for detecting the presence or absence of an abnormality in energization during non-operation.

When the perm device 100 that deforms the hair of the person to be treated is in operation, the current value of the electricity supplied to the electric heating rod 2 for the deformation processing, that is, the operating electricity (alternating current), and the temperature sensor 22 detect it. By measuring the temperature of the electric heating rod 2 in operation by the current measuring unit 12a and the temperature measuring unit 13, the control unit 100 supplies the electric heating rod 2 from the power supply unit 10 during the operating time set by the practitioner. Control to maintain proper electricity. If the electric heating rod 2 and the temperature sensor 22 are not normally energized during the operation, the current value and the temperature under control cannot be controlled within an appropriate range, and the control unit 11 abnormally displays the display unit 14. Is displayed. Therefore, in the above operation, it can be said that the control unit 11 automatically tests whether the energization is normally performed or whether an abnormality has occurred in the energization.

In this example, the perm device 100 is activated by receiving an operation of turning on the power of the main body 1 from the practitioner, but the perm device 100 is capable of immediately deforming the hair by the activation. It does not enter the operating state, but temporarily enters the standby state for the above operation when it is started.
In the standby state of operation, the screen of the display unit 14 rises and can be displayed, and the practitioner waits for each operation reception after activation. The perm device 100 is a standby electricity supply mechanism that supplies electricity necessary for the operation of the control unit 11 during the standby and the operation such as the display of the display unit 14, and is necessary for performing a test during the standby of the operation. It is equipped with a test electricity supply mechanism that supplies electricity.

As the test electricity supply mechanism, the perm device 100 is for the operation of the first test electricity supply mechanism that supplies the test current via the output switch 10c under the control of the output control unit 11a, and the operation of the control unit 11 itself. A second test electricity supply mechanism that supplies a part of the electricity directly or indirectly received by the control unit 11 from the power supply unit 10 (power input unit 10a or transformer 10b), and the main body unit 1 and the power supply rod 2. A third test in which at least one of the electricity storage circuits is provided and a part of the electricity supplied from the power supply unit 10 via the output switch 10c during the deformation processing of the hair and the electricity stored in the electricity storage circuit is supplied. At least one of the electricity supply mechanism and the fourth test electricity supply mechanism in which the main body 1 or the electric heating rod 2 is provided with a battery and supplies the electricity stored in the battery can be adopted.

The standby electricity supply mechanism supplies electricity necessary for the standby to the control unit 11, the display unit 14, the operation unit 15, and other components that are activated and are in the standby state. , The detection unit, and other components necessary for determining the presence or absence of abnormalities in energization and displaying the determination result, are supplied with electricity. In this example, the test electricity supply mechanism adopts the first test electricity supply mechanism.

The energization test during standby may be executed by accepting an operation from the operation unit 15 during standby, or automatically by entering the standby state, that is, automatically by starting. It can be anything that runs the test. When the test is automatically performed by the above activation, the test result can be displayed by accepting the operation from the practitioner.
In the above test during standby, that is, during non-operation, it is not necessary to supply the necessary electricity during operation. Therefore, the test electricity supply mechanism supplies weak electricity that can detect the energized state, and does not heat the electric heating rod 2 to a high temperature as in operation.
In the above example, by starting the perm device 100, the operation is first in the standby state, the operation from the standby operation unit 15 is accepted, and the test is performed during the operation, or the operation shifts to the operation state. However, in addition to this, the perm device 100 selects either the above-mentioned operating state or the above-mentioned operation standby state by the operation of the operation unit 15 in the completely stopped state before the above-mentioned operation standby state. However, both the selected operating state and the standby state of the operation may be able to immediately shift from the completely stopped state.

The standby electricity supply mechanism supplies electricity necessary for the standby to the control unit 11, the display unit 14, the operation unit 15, and other components that are activated and are in the standby state. In this example, the standby electricity supply mechanism is used. In the electricity supply mechanism, both during the operation and during the operation standby, electricity other than the electricity supplied to the electric heating rod 2, in other words, the electricity required for the operation of the main body 1 itself, is supplied to the electric heating rod 2. It is supplied from the power supply unit 10 by a different route from that of the power supply unit 10. That is, the standby electricity supply mechanism is configured as an electricity supply circuit for the main body portion that supplies electricity to the configuration on the main body portion 1 side regardless of whether the perm device 100 is in operation or in operation standby.
The details of each configuration of the perm device 100 will be described below.

Further, a plurality of temperature sensors 22 may be provided on one electric heating rod 2 to detect the temperature at each position inside and outside the electric heating rod 2.
As the temperature sensor 22, when the voltage value of the energized electricity is constant, the electric resistance value changes due to the change in the ambient temperature, and the current value that changes due to the change in the electric resistance value is detected. do. Specifically, a thermistor can be adopted for the temperature sensor 22. However, the temperature sensor 22 of another type other than the thermistor may be adopted and carried out.
For example, general temperature sensors include resistance temperature detectors, semiconductor sensors, and thermocouples in addition to thermistors. Among them, resistance temperature detectors and semiconductor sensors that do not require cold contact compensation like thermistors are the temperature sensors mentioned above. It may be adopted in 22 and carried out. However, it is also possible to provide a cold contact on the main body 1 side and adopt the thermocouple for the temperature sensor 22.

Each electric heating rod 2 may be detachably connected to the electric cord 3 or may be integrally formed with the electric cord 3 and may not be detachable from the electric cord 3.
In this example, the heater 21 can be heated by a current supplied from a power source via a connection plug provided on the end face of the electric heating rod 2, and this heat is transferred to the cylindrical member to be transferred to the cylindrical member. Heats the outer peripheral surface of the cylinder.
In the example shown in FIG. 2A, the electric heating rod 2 is detachably connected to the electric cord 3. The connection will be described in the following description of the electric cord 3.

A conductor wire 32 and a temperature detection wire 33 that electrically connects the temperature sensor 22 and the control unit 11 are passed through (FIG. 4).
In particular, in this example, on the main body 1 side, the sensor lead wire 31 branches from the heater lead wire 31 and is connected to the temperature sensor 22 on the heating rod 2 side. More specifically, in the heater lead wire 31, the sensor lead wire 32 branches from between the current detection unit 12 and the heater 21 to the temperature sensor 22 side. However, the sensor lead wire 32 is not between the current detection unit 12 and the heater 21, but is electrically connected to the temperature sensor 22 side independently of the heater lead wire 31 from the power supply unit 10 (output switch 10c described later). It may be (not shown).

Although not shown, this perm is similar to that described in FIG. 2 of Patent No. 4162634 (Patent Document 1), Patent No. 4162635 (Patent Document 2), and Patent No. 4203368 (Patent Document 3). The device 100 may have the same number of electric cords 3 as the number of electric heating rods 2, and each electric heating rod 2 may be individually connected to the main body 1 by one electric cord 3. That is, the main body side connection plug 34 may be provided for each electric cord 3 connected to the electric heating rod 2.

It is connected by being connected (Fig. 2 (B)). Therefore, the main body side connection plug 34 includes individual terminals corresponding to each of the four electric heating rods 2. However, if electricity can be supplied to each of the four electric heating rods 2 independently, a part of the terminals may be shared between the electric heating rods 2.

In this example, as shown in FIG. 2B, the terminal connection ports 36 are grouped into two in one main body side connection plug 34. One connection port 36 constitutes a terminal for two electric heating rods 2.
Therefore, in this example, there is only one plug locking portion on the main body 1 side for fixing one main body side connecting plug 34, but the one plug locking portion corresponds to the above two connection ports 36. There are two socket openings (not shown). Four sockets 16 electrically corresponding to the four electric heating rods 2 are integrated in the one plug locking portion.
As described above, the main body 1 is formed by gathering a plurality of electric heating rods 2 with one main body side connection plug 34 and consolidating a plurality of sockets 16 into one plug locking portion also on the main body 1 side. It is convenient because a plurality of electric heating rods 2 can be connected at once.

It should be noted that the connection of the four electric heating rods 2 to the main body 1 with one electric cord 3 as a set is merely an example, and as described above, each of the individual electric heating rods 2 is connected to one electric cord 3. It may be individually connected to the main body 1, or may be connected to the main body 1 with one electric cord 3 as a set of, for example, two or three electric heating rods 2. A set of two or more electric heating rods 2 may be connected to the main body 1 by one electric cord.

(Power supply unit 10)
The power supply unit 10 includes a power supply input unit 10a, a transformer 10b, and a plurality of output switches 10c (FIG. 4).
The power input unit 10a receives electricity from the outside and supplies a current to the electric heating rod 2.
Specifically, a plug or a power cord for taking in current from a commercial power source corresponds to a power input unit 10a.
The transformer 10b is electrically connected to the power supply unit 10 and receives a current flowing through the electric heating rod 2 from the power supply unit 10. The transformer 10b is a transformer that supplies the current received from the power supply unit 10 to the electric heating rod 2 and transforms the voltage of the current received from the power supply input unit 10a to an appropriate voltage due to the heat generation of the heater 21.
Each output switch 10c is electrically connected to the transformer 10b.
Each of the output switches 10c is a switch that controls on / off of the current to the heater 21 of the corresponding electric heating rod 2 under the control of the control unit 11. By the on / off control, electricity required for heat generation is supplied from the power supply unit 10 to the heater 21 of the electric heating rod 2.

Electricity for operation is supplied to the control unit 11, the display unit 14, and the operation unit 15 separately from the supply of the above.
The supply line that supplies electricity from the power input unit 10a to the control unit 11 may be provided with a transformer other than the transformer 10a or an AC-DC converter that converts an alternating current into a direct current. However, instead of using a transformer separate from the transformer 10c, the supply line for supplying electricity to the control unit 11 can also be implemented as supplying electricity to the control unit 11 via the transformer 10c. Generally, the transformer 10c generates a required voltage on the secondary side according to the number of turns of the coil on the secondary side (relative to the number of turns of the coil on the primary side). Therefore, in the coil on the secondary side of the transformer 10c, the lead wire that sends the current to the electric heater 2 side at the position of the number of turns that generates the voltage suitable for sending to the electric heater 2 side (transformer 10b and output switch in FIG. 4). The line connecting the 10c) may be connected, and the supply line for sending the current to the control unit 11 side may be connected to the position of the number of turns for generating a voltage suitable for sending to the control unit 11.

Further, a transformer different from the transformer 10a is provided on the supply line for supplying electricity from the power input unit 10a to the display unit 14 and the supply line for supplying electricity to the operation unit 15, which are appropriate for each. It suffices to supply a current of a different voltage. Further, also in supplying electricity to the display unit 14 and the operation unit 15, instead of using a transformer separate from the transformer 10c, electricity is supplied to the control unit 11 via the transformer 10c as described above. It can also be carried out.
Each of the above-mentioned supply lines of electricity to the control unit 11, the display unit 14, and the operation unit 15 constitutes the above-mentioned dedicated supply circuit for the main body unit.
In the supply circuit dedicated to the main body, the supply lines of the control unit 11, the display unit 14, and the operation unit 15 may be separately provided in parallel from the power supply unit 10, but the display unit 14 may be provided separately. Or, a part of the electricity supplied to the operation unit 15 may be provided to be supplied to the control unit 11.

The output control unit 11a operates the output switch 10c (on / off) as described above based on the control signal from the signal generation circuit 5, and supplies a predetermined current to the heater 21 of the electric heating rod 2. The output control unit 11a can adopt the above-mentioned relay (relay) that receives a control signal from the signal generation circuit 5 and operates the output switch 10c.
In this example, the output control unit 11a operates the output switch 10c under the control of the control unit 11 so as to supply the necessary electricity to the electric heating rod 2 when the perm device 100 is operating as described above.
The first test electricity supply mechanism is composed of a control unit 11 and an output control unit 11a. The output control unit 11a operates the output switch 10c so as to receive a test command from the control unit 11 during the operation standby and supply the electricity required for the test of the electric heating rod 2.
The control unit 11 controls the output control unit 11a so that the total time during which the output switch 10c is turned on within a predetermined time is shorter during the test during operation standby than during operation. The electricity supplied at the time shall be weaker than the electricity at the time of operation.

(Current detection unit 12)
The current detection unit 12 detects the current flowing from the output switch 10c to the heater lead wire 31 via the output switch 10c and the heater lead wire 31 in the main body 1. A well-known ammeter can be adopted for the current detection unit 12.
For example, the current detection unit 12 may be composed of a shunt resistance and a voltmeter, and the current value may be calculated from the voltage measured by the voltmeter (voltage drop across the shunt resistance), or the current detection may be performed. A voltmeter may be used for the unit 12, and a configuration in which a current passage is divided into two by using two resistors, that is, a shunt may be adopted.
The current detection unit 12 is connected to the control unit 11 by the first signal line 37.

(Current measuring unit 12a)
The current measuring unit 12a is provided on the first signal line 37 and is interposed between the current detecting unit 12 and the control unit 11. The current measuring unit 12a measures the current value of the current detecting unit 12 and transmits the data signal of the measured current value to the control unit 11.
The current measuring unit 12a measures the current value in the current detecting unit 12 in order to maintain the electric heating rod 2 at the set temperature during the operation of the perm device 100 and transmits the current value to the control unit 11, and also operates during the operation standby. According to the instruction of the control unit 11 according to the test command received by the unit 15, the electricity for the test in the current detection unit 12 is measured and transmitted to the control unit 11.
An OP amplifier (operational amplifier) can be adopted for the current measuring unit 12a. For example, when the above-mentioned shunt resistor is used for the current detection unit 12, the resistance value cannot be increased because the shunt resistor affects the circuit, and the generated voltage becomes too small to measure a minute current, which makes measurement difficult. Become. However, by adopting the above OP amplifier, the resistance value can be increased, so that even an extremely small current can be measured.

(Temperature measuring unit 13)
The temperature measuring unit 13 is provided on the second signal line 38 connecting the temperature detecting line 33 and the control unit 11, and is interposed between the temperature sensor 22 and the control unit 11.

(Display unit 14)
The display unit 14 can switch the display mode and display by operating the operation unit 15.
Here, the test display screen shown in FIG. 3B will be described.
The test display screen shown in FIG. 3B can be called by operating the mode selection button 15a of the operation unit 15, which will be described in the following description of the operation unit 15.
In this example, a maximum of 32 electric heating rods 2 can be connected to the main body 1. The circles displayed arranged in 4 vertical × 8 horizontal on the screen correspond to each of the sockets 16.
In this example, since the four electric heating rods 2 are integrated in one main body side connection plug 34 (FIG. 2B), four sockets 16 corresponding to one main body side connection plug 35 are shown. It is displayed as a set of four circles surrounded by one rectangular frame line 14d (FIGS. 3A and 3B). Therefore, one rectangular frame line 14d corresponds to the one plug locking portion.

In the test screen, the circle 14a whose outline is white and the inside appears black indicates that the electric heating rod 2 (electric cord 3) is not inserted in the socket 16.
Therefore, for the plug locking portion to which the main body side connection plug 35 is not attached, all four circles in the frame line 14 are outlined in white and the inside appears in black.
On the other hand, regarding the electric heating rod 2 connected to the main body 1, in this example, the circle mark 14b which appears to be painted in gray including the above edging indicates that it is normal as a result of the test, and is painted in white including the above edging. The visible circle 14c indicates that the test results indicate that the electric heating rod 2 is overloaded (FIG. 3 (B)).

Actually, in this example, the circle mark 14b that appears to be filled with gray is blue, and the circle mark 14c that appears to be filled with white is orange. Further, although not displayed on the screen shown in FIG. 3B, the circle corresponding to the electric heating rod 2 having the temperature sensor 22 abnormality exhibits another color (for example, yellow). The circles on the main body 11 side also exhibit another color (for example, purple).
Further, in this example, the circle mark is orange even when the heater 21 is disconnected. Since the display unit 14 is provided with an error type display portion 14e indicating the type of abnormality, does the orange circle indicate the overload of the electric heating rod 2 when looking at the error type display portion 14e? It is possible to determine whether or not the wire is broken.
However, in order to make it easier to distinguish from the overload of the electric heating rod 2, the disconnection of the heater 21 may exhibit a color different from orange.

(Operation unit 15)
The operation unit 15 is provided with a button, a slider, or a switch operated by the practitioner. In this example, the operation unit 15 includes a plurality of operation buttons 15a to 15h (FIG. 3A).

The mode selection button 15a is a button for switching the display mode (operation mode) of the display unit 14. For example, by operating the mode selection button 15a, various input modes (input screens) and abnormality display modes (error display screens) for inputting and displaying the operating temperature and time can be called. While the input screen called by the mode selection button 15a is being displayed, the set temperature of the heater 21 can be raised by operating the temperature addition button 15b, and the set temperature of the heater 21 can be lowered by operating the temperature subtraction button 15c. Further, while the input screen is being displayed, the time for maintaining the set temperature can be lengthened by operating the time addition setting button 15d, and the time can be shortened by operating the time subtraction button 15e.
The set temperature data input by operating the temperature addition button 15b and the temperature subtraction button 15c is stored in the set temperature storage unit of the perm device control system described later, and is stored by operating the time addition setting button 15d and the time subtraction button 15e. The input set time data is stored in the set time storage unit described later (not shown).

In this example, the main body 1 is provided with a power switch (not shown) for turning on the main power separately from the start button.
When the practitioner operates the power switch to turn on the main power before the perm device 100 is in a completely stopped state (a state in which the main power is turned off) before the operation standby, that is, before the start, the perm device 100 starts and waits for the operation. It becomes a state. The above input screen can be called during the operation standby to set the heat generation temperature and heat generation time of the heater 21. By pressing the start button 15f during the start standby, the perm device 100 is put into operation, electricity necessary for hair deformation processing is supplied to the electric heating rod 2, and the heater 21 generates heat toward the set temperature. The abnormality display mode (error display screen) can be called by operating the operating mode selection button 15a.
By pressing the stop button 15g during operation, the perm device 100 returns to the operation standby state again. The test mode (test display screen during operation standby) can be called by operating the operation standby mode selection button 15a.
By pressing the menu button 15h during operation standby, it is possible to call up the menu screen for changing the color scheme of the screen and adjusting the brightness of the screen. In this example, the temperature addition button 15b, the temperature subtraction button 15c, the time addition setting button 15d, and the time subtraction button 15e also serve as operation buttons for changing or adjusting settings on the menu screen.
By operating the power switch during operation standby to turn off the main power, the system returns to the completely stopped state before the startup.
As described above, in this example, the perm device 100 is put into the operation standby state by operating the power switch provided separately from the start button 15f, and the perm device 100 is operated by operating the operation standby start button 15f. It was supposed to work. In addition, the start button 15f can be used as a substitute for the power switch. Specifically, in the state where the perm device 100 is completely stopped before the start, the perm device 100 is put into the start standby state by pressing the start button 15f once, and further (as the second time) the start button 15f. By pressing, the perm device 100 may be put into an operating state. By turning on the main power supply with the start button 15f in this way, it can be carried out without providing the power supply switch.
A touch panel may be adopted for the display unit 14, and the display unit 14 may also serve as at least a part of the operation unit 15.

For each electric heating rod 2, the data accommodating unit m100 has a current value accommodating unit m15 accommodating the current value measured by the current measuring unit 12a and a resistance value accommodating unit m16 accommodating the resistance value measured by the temperature measuring unit 13. The electric heating rod determination accommodating unit m17, the temperature sensor determination accommodating unit m18, and the main body side determination accommodating unit m19 are provided. The data accommodating portion m100 is provided for the number of sockets 16 (FIGS. 4 and 5).
Further, the abnormality display system m includes a display order storage unit m6 for storing the priority of the abnormality to be displayed when a plurality of types of abnormalities in the energized state overlap.

The command unit m1, the operation determination unit m2, the standby determination unit m3, the electric heating rod abnormality determination unit m4, the temperature sensor abnormality determination unit m5, and the display order storage unit m6 are mainly the arithmetic unit and the control of the microcomputer 4. It is composed of the device, the storage device, and the installed abnormality display program.
The main current upper limit storage unit m7, the main current lower limit storage unit m8, the sub-current upper limit storage unit m9, the sub-current lower limit storage unit m10, the main first reference resistance storage unit m11, the main second reference resistance storage unit m12, and the sub-resistance. Each of the upper limit storage unit m13, the sub-resistance lower limit storage unit m14, and the data storage unit m100 is mainly composed of the storage device and the installed abnormality display program of the microcomputer 4.

The abnormality display system m constitutes a part of the perm device control system. Specifically, by introducing the perm device control program into the microcomputer 4, the abnormality display program is also introduced into the microcomputer 4 as a part of the perm device control program, and the perm device control system including the abnormality display system m is introduced. Will be built. At the time of manufacturing the perm device 100, the microcomputer 4 into which the perm device control program is introduced is mounted on the perm device 100. However, after the user of the perm device 100 (the staff of the beauty salon) purchases the perm device 100, the perm device 100 or another computer connected to the perm device 100i is connected to the server on the network via the network and the server is concerned. It is also possible to download the above-mentioned perm device control program recorded in the above and introduce it into the perm device 100. Further, the perm device control program written on an optical medium such as a CD or a DVD may be introduced into the perm device 100 by a user of the perm device 100 through a separate computer connected to the perm device 100. Further, the abnormality display program may be configured separately from the perm device control program, and may be additionally installed in the perm device 100 into which the perm device control program is introduced. In the above, the perm device 100 may be provided with an interface such as a USB or LAN cable jack that can be connected to the separate computer.

With the perm device control system, the temperature of the electric heating rod 2 during operation can be set by the practitioner from the operation unit 15. Further, the control unit 11 includes a timer, and the perm device control system can also set the heat generation time of the heater 21 at the set temperature.
Further, in this example, the perm device control system can set the temperature of the electric heating rod 2 during operation in multiple stages, and the control unit 11 refers to the timer to detect the passage of the set operating time. Therefore, the heat generation temperature can be changed.

For example, in the perma device control system, the electric heating rod 2 is heated for 7 minutes at a treatment temperature of 50 degrees Celsius, the electric heating rod 2 is heated for 13 minutes at 70 degrees Celsius after 7 minutes, and 60 degrees Celsius after 13 minutes. It is possible to set the electric heating rod 2 to generate heat for 5 minutes.
The control unit 11 causes the output control unit 11a to open and close the output switch 10c so that the temperature becomes the temperature set above. When the temperature of the temperature sensor 22 measured by the temperature measuring unit 13 does not reach the set temperature, the control unit 11 causes the output control unit 11a to control the output switch 10c so as to lengthen the total time of turning on the output switch 10c. On the contrary, when the temperature of the temperature sensor 22 measured by the temperature measuring unit 13 is about to exceed the set temperature, the output control unit 11a is controlled to lengthen the total time of turning off the output switch 10c.

The perm device control system includes a set temperature storage unit that holds the set temperature during operation and a set time storage unit that holds the set time (not shown), and the control unit 11 measures the temperature during operation. The measured temperature data of the unit 13 is compared with the set temperature data held by the set temperature storage unit, and the output control unit 11a is made to control the on / off of the output switch 10c.
On the other hand, in the abnormality display system, regardless of the temperature data (temperature data) stored in the set temperature storage unit, the upper and lower limits of the electrical resistance, which is the temperature for normal operation, are the main resistance upper limit storage unit. It is stored in m11 and the main resistance lower limit storage unit m12. However, unlike this example, the upper limit current value and the lower limit current value are calculated each time based on the set temperature data stored in the set temperature storage unit and the set time data stored in the set time storage unit. The control unit 11 can also be implemented as storing the data of the upper limit current value in the main current upper limit storage unit m7 and storing the data of the lower limit current value in the main current lower limit storage unit m8. In addition, regardless of the calculation of the upper limit current value and the lower limit current value, a table that defines the range of the upper limit current value and the lower limit current value for each set temperature shall be provided, and normal operation shall be performed with reference to the table. It can also be implemented that the upper limit value and the lower limit value of the electric resistance, which is the temperature, are stored in the main resistance upper limit storage unit m11 and the main resistance lower limit storage unit m12.
