Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heated permanent device.

The mainstream of conventional permanents is a method called "cold perm" in which hair is reacted with a chemical solution at room temperature. However, in this type of permanent method, strong chemicals are used to react with the hair (for example, thioglycolic acid perm solution) at room temperature, and the chemicals may cause damage to the hairdresser's skin. There is a risk of damaging the customer's hair, and since the beautician judges the reaction time of the chemical solution based on the texture and sensation of the hair, it is easy to have too much or too little hair on the permanent, so it cannot be said to be very desirable. Ta.

Therefore, recently, in order to eliminate even some of the above-mentioned drawbacks, a few permanent devices have been developed that employ a method of heating the hair and reacting it with a chemical solution. However, this type of permanent device that is currently being developed and commercialized is either a method in which hair is wrapped around a curl rod that has stored heat in advance and heated, and a chemical solution is reacted with the hair, or a method is used in which hot air is applied to hair that has been coated with a chemical solution. This is a method of heating the hair and causing the chemical solution to react, and while both have the advantage of being able to weaken the chemical solution because they are heating methods,
The former has the drawback that the temperature of the curl rod drops quickly, making it impossible to maintain the chemical reaction at an appropriate temperature, and it is extremely difficult to adjust the reaction time. In addition, there is a concern that the chemical solution will be dried by the hot air, and there is a risk that the chemical solution will become completely useless.

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 a mist generated at room temperature, it is possible to use a weak chemical solution and to ensure that the desired degree of permanentness is obtained.
Furthermore, by preventing the chemical solution from drying out, smooth permanent waves can be created.

It is. Therefore, when inputting information to the controller 60, it is sufficient to press the button switch corresponding to the mark placed on the customer card 68.

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 represents one heating block circuit including one heating element 50, its temperature control means, and timer means, and the other heating elements 50, 50, . . . It constitutes a heating block circuit and is omitted from the drawing. 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,
A timer motor 71 is connected in parallel to this heating element circuit, and this parallel circuit is connected to an overtemperature preventer 7.
3. 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 a resistor 7 as shown in the figure.
7 and 78, 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) forms a series circuit with the spray switch 81 and is connected 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 an overtemperature rise preventer 73,
An AC power source 74 is connected in series with a power switch 61.
Connect to. On the other hand, a rectifier circuit including a diode 84 and a capacitor 85 is connected to the secondary side of the transformer 83 to form a DC power source. This DC power supply includes a heating element that senses the temperature of the hair, that is, a negative characteristic thermistor 66, a variable resistor 86 for setting the heating temperature, a PNP transistor 87, an NPN 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. In addition, the variable resistor 86 of each heating block circuit
are set to the same value by a single operation. Further, the thyristor 70, the gate drive circuit of the thyristor 70, and the temperature detection circuit constitute a temperature control means for controlling the temperature of the heating element 50.

Furthermore, the above DC power supply has a PNP type transistor 9.
3, NPN type transistor 94, resistor 95,9
6,97, relay 98, diode 99,100
The transistor 93 has its base connected to the diode 9.
9 to the base of transistor 87, so that when the thermistor 66 is disconnected, the potential at the base of transistor 87 is immediately transmitted to the base of transistor 93. 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. In addition, the thermistor disconnection detection circuit detects disconnection of the thermistor, opens the relay contact 101 of the relay 98, stops the power supply to the heating element 50, and performs a heating operation in which the heating operation by the heating element 50 is stopped. This constitutes a stopping means.

Next, its operation will be explained. When applying permanent hair, curl the customer's hair with curl rods 67,6.
7... and apply the weakened permanent solution all over the hair, then attach the thermistors 66, 66... with pins to the curl rods 67, 67... located approximately in the center of each block (a to e), respectively. Install. Then, the customer card 68 is set on the controller 60, and the heating temperature and heating time are set for each of the blocks a to e by operating the button switch at the part marked in advance. Next, after checking the amount of water in the supply tank 28, close the spray switch 81 and turn on the power switch 61.
When the timer contact 72 is closed due to the time setting and the relay contact 101 is closed, heating operations by the heating elements 50, 50, etc. and spraying operations 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 the variable resistor 86, including the thermistor 66,
Due to the action of the DC bridge circuit constituted by resistors 89 and 90, transistor 87 is turned off, and transistor 88 at the next stage is also turned off. Therefore, no input current flows through the photocoupler 92, and the internal phototransistor is in an off state.
When the power switch 61 is closed, the discharge current of the capacitor 75 that is being charged flows into the gate of the thyristor 70, and the thyristor 70 becomes 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 its temperature reaches the set temperature, the resistance value of the thermistor 66 that senses the hair temperature decreases, and the transistor 87 is turned on by the action of the above-mentioned DC bridge circuit. state, and the transistor 88 at the next stage is also turned on. Then, an input current flows to the photocoupler 92, 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 continues until the set time has elapsed, and when the set time has elapsed, the timer contact 72 opens and the power supply to the heating element 50 is stopped, and the heating operation by the heating element 50 ends. 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 blower 12
The air sucked in from the intake ports 11, 11, .
5 into the water tank 16. and aquarium 1
The air that has flowed into the tube 6 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 then flows from the discharge port 44 to the baffle plate 43.
Due to this action, the fog is widely diffused inside the bonnet 35. 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. It turns out. Then, the spent fog is discharged to the outside from the exhaust holes 53, 53, . . . through the ventilation holes 54, 54, . . . or,
The fog is removed from the inner cover 37 inside the bonnet 35.
The water drips onto the inner surface and the protective net 52, etc., and drips onto the outer ring plate 38 and inner ring plate 45, but the dripping water is guided by the upright wall 49 to the drain outlet 39 located at the lowest rear part, and flows to the edge of the opening 48. There is no chance of dripping on the floor or 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, permanent treatment is carried out by heating the hair while spraying it inside the bonnet 35, and since the heating time and temperature can be adjusted arbitrarily in consideration of the chemical solution, hair quality, etc., the chemical solution does not dry. It is possible to make the hair react sufficiently without causing any damage, and it is possible to reliably obtain the desired permanent wave.
If you want to obtain the same permanent wave in the future, you can use the same customer card 68 and perform the input operation on the controller 60, and the same permanent wave will be obtained without any excess or deficiency in the degree of application. Also, if you want to have a partial change in the amount of hair depending on the hairstyle, each block a
The heating time may be changed for each time from e to e to change the heating state. Although not specifically mentioned in this embodiment, it would be preferable to provide a notification means to notify the completion of the heating operation in all the heating blocks when the heating operation is completed.

During the hair heating operation, the thermistor 66,
If even one of the thermistors 66 is disconnected, the thermistor disconnection detection circuit detects the disconnection, cuts off the power to all the heating elements 50, 50, and the spray device, and performs subsequent heating and spraying operations. stop. That is, when any thermistor 66 is disconnected, the voltage between the lead wires becomes high, and the base potential of the transistor 87 is transmitted to the base of the transistor 93 via the diode 99, turning the transistor 93 off, and the next stage transistor is turned off. 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, after using water as the spray liquid by the spray device and setting the heating temperature by the heating elements 50, 50 to the maximum, the spray switch 81 is turned on.
When the power switch 82 is closed, the mist ejected into the bonnet 35 is heated by the heating elements 50, 50.
It is heated by ... and immediately turns into steam, functioning as a steamer. In this case, the thermistors 66, 66... are connected to the heating elements 50, 50.
Keep it outside the heating range of the heating element 5.
0, 50... is a continuous heating state.

In addition, if the blower 12 is separated from the spray device and the circuit is configured such that the blower 12 can be controlled independently, hot air can be obtained by the action of both the blower 12 and the heating elements 50, 50, and it can be used as a normal hair dryer. Available for use. 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, as in this embodiment, the bonnet 35 and the main body 5
If the height and direction of the controller 60 can be adjusted in a timely manner, the controller 60 can be placed in the most preferable condition, which is good in terms of operation. However, as shown in FIG. It is also possible to integrate the controller 60. 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 further enhance the effect of partial heating. That is, the structure is such that the heating element 50 is surrounded by a reflective plate 102, one end of the frame formed by the reflective plate 102 faces inside the bonnet 35, and the other end is closed with a transparent heat-resistant glass 103. It has a structure that looks out from the bonnet 35,
It heats the hair with radiant heat by discharging convective heat to the outside.

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, in the permanent device of the present invention, if even one of the temperature detection elements of the temperature control means fails, all subsequent heating operations by the plurality of heating elements of the heating means are stopped. It is possible to reliably prevent overheating due to a malfunction of the detection element, thereby eliminating the risk of burns caused by overheating and increasing safety.Furthermore, by stopping all heating operations, the user can be assured of the temperature. It is possible to reliably recognize failure of the detection element and reliably prevent failure of partial permanent treatment on the hair part.
