Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating type permanentette device.

The mainstream of conventional permanets is a method called "cold perm" in which hair is reacted with a chemical solution at room temperature.

However, in this permanet method, strong chemicals are used to react with the hair (for example, thioglycolic acid perm solution) at room temperature, and the chemicals may harm the hairdresser's skin. There is a risk of damaging the customer's hair.
Since judgments are made based on sensation, etc., there is a tendency for the degree of permanet to be over or under, and it cannot be said to be very desirable. Therefore, recently, in order to eliminate even one part of the above-mentioned drawbacks,
Two to three permanet devices, which employ a method of heating hair and reacting it with a chemical solution, have been developed for a few days.
This type of permanet device, which is currently available, either wraps hair around a curl rod that has stored heat in advance and heats it, and then reacts a chemical solution to the hair. Both methods have the advantage of weakening the chemical solution because they are heated, but the former method lowers the temperature of the Karlrod quickly and cannot maintain the chemical reaction at an appropriate temperature. Moreover, the latter has the disadvantage that it is very difficult to adjust the reaction time, and the latter has the disadvantage that the chemical solution applied to the hair may be dried by the hot air before it reacts, so there is no chemical solution at all. There is a possibility that it will become meaningful.

However, the present invention has been made to eliminate the above-mentioned drawbacks, and its characteristics include allowing a chemical solution to react with hair in a heated state, and making it possible to arbitrarily adjust the reaction temperature and time. By applying moisture to the hair using mist generated at room temperature, it is possible to use a weak chemical solution, and the desired degree of permanet application is reliably obtained, and the drying of the chemical solution is prevented. The reason is that it is possible to create smooth permanent waves.

Embodiments of the present invention shown in the drawings will be described in detail below.

At the tip of this sensor cord 65, there is a heat-sensitive element, for example, a negative characteristic thermistor 66, 66, . . .
They are placed facing each other. The thermistors 66, 66... are attached to the hair using curl rods 67, 67 around which the hair is wrapped.

The heating time is set individually for each block a to e of the hair part, and the heating temperature is set commonly for all blocks a to e. In addition, the heating temperature and heating time of blocks a to e are selected according to the customer's hair type, hairstyle, etc., and predetermined through holes 69 are placed on the customer card 68.
, 69... are to be marked. Therefore,
When inputting information to the controller 60, the bush switch corresponding to the mark placed on the customer card 68 may be pressed. Next, the control circuit will be explained with reference to the electric circuit diagram shown in FIG.

In addition, in FIG. 6, the circuit within the one-dot chain line corresponds to one heating element 5.
0, its temperature control means, and timer means, and each of the other heating elements 50, 50.
. . . similarly constitute the heating block circuit, and their drawings are omitted. Of course, all heating block circuits are connected in parallel relationship. The heating element 50 connects a thyristor 70 and a timer contact 72 in series to form a heating element circuit, and a timer motor 71 is connected in parallel to this heating element circuit, and this parallel circuit is connected to an overtemperature preventer 73.
, are connected to an AC power source 74 via a power switch 61 in series.

The timer motor 71 and timer contacts 72 constitute timer means for setting and controlling the heating time by the heating element 50, and the timer means for each heating block can be set individually. The gate drive circuit of the thyristor 70 includes a capacitor 75, a diode 76, and resistors 77, 7 as shown in the figure.
8, and causes zero voltage ignition of the thyristor 70. A resistor 79 and a diode 80 are inserted and connected to protect the gate of the thyristor 70.
The ultrasonic spray device (including the blower 12) has a spray switch 8
1 to form a series circuit and connect it in parallel to the heating element circuit.

82 is a variable resistor that adjusts the amount of mist generated, that is, the amount of spray.

The primary side of the transformer 83 is connected to an AC power source 74 via a temperature overrise preventer 73 and a power switch 61 in series.

On the other hand, a rectifier circuit consisting of a diode and an 8-hole capacitor 85 is connected to the secondary side of the transformer 83 to form a DC power source. This DC power supply includes a heat-sensitive element that senses the temperature of the hair, that is, a negative characteristic Sanormistor 66, a variable resistor 86 for setting the heating temperature, a PNP type transistor 87, an NPN type transistor 88, and resistors 89, 90, and 91. A detection circuit is connected, and this temperature detection circuit is connected to the gate drive circuit of the thyristor 70 via a photocoupler 92. Photocoupler 92 insulates AC power supply 74 and thermistor 66 to prevent electric shock. Note that the variable resistors 86 of each heating block circuit are set to the same value by a single operation. Furthermore, the above DC power supply has a PNP type transistor 9.
3. NPN transistor 94, resistors 95, 96, 97
, a relay 98, and diodes 99, 100 are connected to the thermistor disconnection detection circuit, and the transistor 93 has its base connected to the transistor 87 through the diode 99.
The base of the transistor 87 is connected to the base of the transistor 93 so that the potential of the base of the transistor 87 is immediately transmitted to the base of the transistor 93 when the thermistor 66 is disconnected.

Therefore, the threshold voltage of the thermistor disconnection detection circuit is set higher than that of the temperature detection circuit described above. A relay contact 101 of the relay 98 is inserted and connected to the next stage of the overtemperature rise preventer 73, and the relay 98 closes the relay contact 101 when energized and opens when it is de-energized. Incidentally, the overtemperature rise preventer 73 is arranged to sense the temperature inside the bonnet 35. Next, its operation will be explained.

When applying a permanent product, wrap the customer's hair around the curl rods 67, 67, etc., apply the weakened permanent solution all over the hair, and then apply the weakened permanent solution to the hair at approximately the center of each block (a to e). The thermistors 66, 66, . . . are attached to the curl rods 67, 67, . . . with pins, respectively. Then, by setting the customer card 68 on the controller 60 and operating the bush switch at the part marked in advance, the heating temperature and each block a to e can be adjusted.
Set the heating time for each time. Next, after checking the amount of water in the supply tank 28, close the spray switch 61 and close the power switch 61. Since the timer contact 72 is closed by the time setting and the relay contact 101 is closed, the heating element 50, The heating operation by 50... and the spraying operation by the spray device are started. That is, in the initial stage of heating, the temperature of the hair is low and the resistance value of the thermistor 66 is large, so a DC bridge is constructed of the thermistor 66, variable resistor 86, and resistors 89 and 90! Due to the action of the circuit, transistor 87 is turned off, and transistor 88 at the next stage is also turned off.

Therefore, no input current flows into the photocoupler 92, and the internal phototransistor is in an off state, and the discharge current of the capacitor 75, which is being charged when the power switch 61 is closed, flows into the gate of the thyristor 70. Thyristor 7
0 will be conductive. As a result, the heating element 50 is energized and starts and continues to heat the hair. When the hair is heated by the heating element 50 and the temperature of the heating element 4 reaches the set temperature, the resistance value of the thermistor 66 that senses the hair temperature decreases, and the transistor 87 is turned on, and the next stage transistor 88 is also turned on. Then, photocoupler 9
Input current flows through 2 and the internal light emitting diode emits light,
The phototransistor receives light and turns on, and the discharge current of the capacitor 75 flows through the phototransistor and no longer flows to the gate of the thyristor 70. As a result, the thyristor 70 becomes non-conductive, and the heating element 50 is not energized and stops heating the hair. Then, when the temperature of the hair decreases again, the resistance value of the thermistor 66 increases, and the thyristor 70 becomes conductive as described above, and the heating element 50 is energized again to heat the hair.

In this way, the heating element 50 is repeatedly energized, and the temperature of the hair is maintained at the set temperature. , Such a heating operation is continued until the set time has elapsed, and when the set time has elapsed, the timer contact 72 is opened and the power supply to the heating element 50 is stopped, and the heating operation by the heating element 50 is completed. Of course, the other heating elements 50, 50, . . . are each controlled in the same manner as described above, and perform heating operations to maintain the temperature of the hair at the set temperature until the respective set times have elapsed. On the other hand, inside the bonnet 35 where such a heating operation is being performed, a mist generated at room temperature is sprayed by a spraying device.

That is, the air sucked from the intake ports 11, 11, . You will be guided inside. The air that has flowed into the water tank 16 flows into the guide tube 26 together with the mist generated at room temperature, passes through the connection hose 27 and the spray nozzle pipe 42, and is sprayed into the bonnet 35 from the discharge port 44 by the action of the baffle plate 43. It will spread widely. Therefore,
This mist provides appropriate moisture to the hair, prevents the permanent solution, that is, the chemical solution applied to the hair, from drying out due to heating by the heating elements 50, 50, etc., and allows the chemical solution to sufficiently react with the hair. become. Then, the spent fog is discharged to the outside from the exhaust holes 53, 53, . . . through the ventilation holes 54, 54, . . . Further, the mist is generated inside the bonnet 35 on the inner surface of the inner cover 37, the protective net 52, etc., and drips onto the outer ring plate 38 and the inner ring plate 45, but the dripping water is kept at the rear lowest position by the upright wall 49. It is guided to the drain outlet 39 and does not drip from the edge of the opening 48 on the floor, especially on clothes. Therefore, it is sufficient to connect a hose to the drain outlet 39 and guide it to an arbitrary location for discharge. As mentioned above, the permanent is Bonnet 3
It is carried out by heating the hair while spraying on the hair.
In addition, the heating time and temperature can be adjusted as desired by taking into consideration the chemical solution, hair type, etc., so the chemical solution can be reacted sufficiently with the hair without drying, and the desired permanent wave can be reliably obtained. .

If you want to obtain the same permanent wave in the future, use the same customer card 68 as this time and press the controller 60.
If you perform these input operations, the same permanent wave will be obtained, and there will be no excess or deficiency in the degree of application. Further, if you want to partially change the degree of curl depending on the hair style, you can vary the heating state by changing the heating time for each block a to e. Although not specifically mentioned in this embodiment, it would be preferable to provide a notification means for notifying the completion of the heating operation in all the heating blocks when the heating operation is completed. During the hair heating operation, if even one of the thermistors 66, 66... is disconnected, the thermistor disconnection detection circuit detects the disconnection, and all heating elements 50, 50... and the spray device are disconnected. Cut off the power supply and stop further heating and spraying operations. That is, if any thermistor 66 is disconnected, the voltage between the lead wires increases and the transistor 9
Transistor 87 via diode 99 to the base of 3
The base potential of is transmitted, the transistor 93 is turned off, and the next stage transistor 94 is also turned off. As a result, current no longer flows through the relay 98, and the relay contact 101 returns to open to stop the heating operation and spraying operation. The permanent device of this embodiment can also be used as a steamer.

That is, water is used as the spray liquid by the spray device, and the heating element 5
After setting the heating temperature by 0, 50, .
It is heated by 0... and immediately turns into steam, thus functioning as a steamer. In this case, the thermistors 66, 66... are placed outside the heating range of the heating elements 50, 50...
... is a continuous heating state. In addition, blower 1 is used from the spray device.
If the circuit configuration is such that the air blower 12 can be independently controlled by separating the air blower 12 and the heating elements 50, 50...
Hot air is obtained by both functions, and it can be used as a regular hair dryer.

Of course, the temperature of the hot air can be arbitrarily set and controlled by the controller 60 and thermistors 66, 66, . . . . Furthermore, if a plurality of replenishment tanks filled with different spray liquids are prepared in advance, the apparatus can be used for various purposes simply by replacing the replenishment tanks.

Incidentally, if the height and direction of the controller 60 can be adjusted independently of the bonnet 35 and the main body 5 as in this embodiment, the controller 60 can be placed in the most preferable condition, resulting in better operation. However, it is also possible to integrate the controller 60 into the main body 5 as shown in FIG.

Further, the thermistors 66, 66, . . . may be placed at predetermined positions using a net that is placed over the hair. In FIG. 8, an infrared lamp is used as the heating element 50, and the hair is heated by the radiant heat of the heating element 50 to enhance the effect of partial heating on the hair. That is, the configuration is such that a heating element 50 is surrounded by a reflective plate 102, and a reflective plate 1
One end of the frame formed by 02 faces the inside of the bonnet 35 and is closed with a transparent heat-resistant glass 1043, and the other end faces the outside of the bonnet 35, and convection heat is discharged to the outside and the hair is heated by radiant heat. It heats up. In this embodiment, the heating time by each heating element can be individually controlled, but it is also possible to set and control the heating time by each heating element individually while keeping the heating time constant. Heating time. Both temperatures may be individually set and controlled.

In short, any device may be used as long as it is possible to individually set and control at least one of the heating time and heating temperature of each heating element to individually set the heating state of hair by each heating element. As described above, the heating type permanent device of the present invention is equipped with a replenishment tank that replenishes the spraying liquid to the spraying device and guides air from the blower to the spraying device.
There is no need to separately provide a guide plate for guiding the air from the air blower of the spraying device, so the configuration can be simplified and assembly can be performed easily.
