[Detailed Description of the Invention] This invention relates to a hair curler, and an object of the present invention is to prevent water droplets from being discharged in a steam type hair curler to ensure the generation of steam, thereby enabling safe and effective curling. There is.

A first embodiment of the invention is shown in FIGS. 1 to 7.

That is, this hair curler has a cylindrical housing 1 with a discharge port 2 and an ordinary curling brush 3. Blow brush 4
Attachments such as those shown in FIG. 7 are removably attached, and a rotary connector 6 is provided at the center of the suction port 5 side, and a power cord 7 is pulled out. The attachments (3, 4) and the discharge port 2 are connected by an attachment/detachment button 10 supported by a return spring 8 and provided with a claw 9.

The inside of the housing 1 is hollow, and the steam generator 1 is installed sequentially from the discharge port 2 side to the upwind suction port 5 side.
1. Hot air heater 12. Water tank 13. A motor 14 and a fan 15 are provided.

These are arranged in one row on a concentric axis approximately at the center of the cross section of the housing 1, and the gaps between the outer periphery of each part except the heater 12 and the inner surface of the housing 1 form a ventilation passage 16. A course changeover switch 17 is provided in the housing 1 at the position of the steam generator 11.

As shown in FIG. 2, the steam generator 11 is arranged in a heat-resistant cylinder 18, and a water absorbent body 21 made of metal foam or glass fiber is sandwiched between two heat plates 19 and 20, and one end of the water absorbent body 21 is sandwiched between two heat plates 19 and 20. A water inlet 22 is provided at one end, and a steam outlet 23 is formed at the other end, and the steam outlet 23 is directed toward the outlet 2 of the housing. A heater 27 using a positive temperature coefficient thermistor (referred to as a PTC element) is installed in the side frames 24.25 formed on the upper and lower surfaces of the hot plate 19.20 via an insulating plate 26 made of alumina, and a resin 28 is installed by simultaneous molding. It's molded. Furthermore, a normally open type thermoswitch 29 is attached to the lower side frame 25 to detect the temperature of the hot plate 19,20.

This steam generator 11 has a support member 30 and a heat-resistant cylinder 18.
The outer periphery of the steam generator 11 and the heat-resistant cylinder 18
The space between them is the ventilation passage 16. When this steam generator 11 is energized to the heater 27 and generates heat, the insulating plate 2
The hot plate 19.20 is heated via the water absorber 2.
1 and thermoswitch 29 are heated. When the hot plates 19, 20 reach a predetermined temperature suitable for generating steam, the thermoswitch 29 is activated and closes the switch contact. Furthermore, when water is supplied to the water absorbing body 21, the water spreads over the entire heater heat transfer surface of the water absorbing body 21 due to capillary action 9, and steam is efficiently generated by the heat of the heater 27, which is ejected from the steam outlet 23. .

The hot air heater 12 is a circular plate using a PTC element and has honeycomb-shaped holes 12a formed in the thickness direction, and an electrode plate 32 with a ventilation hole 31 formed in the center is sandwiched between the two heaters 12. Further, both outer surfaces of the heater 12 are sandwiched between electrode plates 33 and 34 of the same shape, and are held together by a curved spring 35a of a cylindrical holder 35. Porous 12a
It is heated by ventilation through the ventilation holes 31, and hot air is discharged toward the steam generator 11 side. N is a temperature heater, and 32a and 33a are terminals.

The water supply tank 13 has a bellows type telescopic structure, and the axial direction...
A fixing part 36 is attached to one end of the housing 1, and this fixing part 36 is fixed within the housing 1.
A presser frame 37 is attached to the other end and is slidably supported within the housing 1, and a compression coil spring 38 arranged around the outer periphery of the motor 14 presses the presser frame 37 to compress and bias the water tank 13. There is. The fixed part 36 has a solenoid valve 39 and a water injection device 40 as shown in FIG. Water injection device 40
As shown in Fig. 5, the rubber pusher is attached to the housing 1:
A stopper 42 is provided below the push-piece 41, a valve 43 is provided below the stopper 42, and the valve 43 is pressed against the stopper 42 by a coil spring 44a. A water injection hole 44 is formed in communication. To inject water into the water tank 13, insert the nozzle 46 of the water injector 45 into the rubber bushing 41, push down the valve 43 through the stopper 42, pinch and compress the middle part of the water injector 45, and then pour water into the water tank 13 through the opened water inlet 44. Press fit inside. This pressure pushes the coil spring 38, causing it to contract and the water supply tank 13 to expand. When the nozzle 46 is pulled out, the valve 43
is returned by the coil spring 44a and closes the water injection hole 44. Note that during the water injection process, the rubber bush 41 comes into close contact with the nozzle 46, thereby preventing water from leaking to the outside of the housing l.

The solenoid valve 39 is a normally closed type, and the yoke 47. Coil frame 48, coil 49. Plunger with valve 50. Return (5) The return spring 51 causes the valve at the tip of the plunger 50 to close the valve water outlet 52 and seal the inside of the water tank 13. When the coil 49 is energized, the plunger 50 is attracted, the water outlet 52 is opened, and the tank water is pushed out by the spring force of the coil spring 38. This nozzle water outlet 52 and the water inlet 22 of the steam generator 11 are connected by a pipe 53, and a solenoid valve 39 is connected to the water absorbing body 21.
Water is supplied under controlled conditions.

The motor 14 is provided with a shaft 54 facing the suction port 5 side of the housing 1, and is fixed within the housing 1 by a mounting arm 55 that supports the end of the coil spring 38. fan 1
5 is fixed to its shaft 54.

FIG. 6 shows the control circuit of this hair curler.

The course changeover switch 17 has three interlocking changeover contacts S~
Fixed contacts A 3 -C for each contact S□ - S3 are simultaneously switched by S. R is the voltage division resistance of the motor, D
Yo ~ D4 is the bridge diode, P is the thermo switch 2
9 normally open contacts.

(6) The operation of this hair curler is as follows:
By switching, there are steam course, steam set course, and hot air course operations. The sweet steam course is a case where the switching contacts S to S3 are brought into contact with the contact A. At this time, the heater 27 of the steam generator 11 generates heat, and the motor 14 rotates at a low speed due to the resistance R. Furthermore, the hot plates 19 and 20 of the steam generator 11 are connected to the heater 2.
7, when the predetermined temperature is reached, the contact P of the thermoswitch 29 closes, the coil 49 of the solenoid valve 39 is energized, and the pulp water outlet 52 opens. The water is then supplied to the water absorbent body 21, where the water absorbent body 21 is heated and thus generates steam. As a result, a small amount of a mixture of cold air and steam is discharged from the discharge port 2 of the housing 1 and the Suita port 56 of the attachment, and when applied to the hair, the hair becomes wet.
It can be used for straightening curls or as a simple treatment steamer. The reason for using a small amount of air (5I!/m1n in the example) is to increase the density of the steam and improve the wetting characteristics (a large amount of air dilutes the steam and worsens the wetting characteristics).

Next, the steam set course is the course changeover switch 17.
This is a case where the contacts S□ to S3 are switched to the contact B. In this case, in addition to the above-described operation, the heater 12 generates heat. As a result, hair can be treated with a mixture of a small amount of hot air (Example 5 I!/min) and steam, and the curl brush 3
For example, heat the hair curling part of the blow brush 4 to 80°C180%.
It is possible to adjust the humid air condition.

When hair is wrapped with a curling brush that emits moist air like this, the dehydration from each hair can be reduced, there is no damage to the hair, and the curling performance is much stronger than that of conventional hot air curl dryers. can get. In addition, by making it possible to continuously emit a mixture of steam and hot air, compared to conventional curl dryers with steam that have the operation of ``wetting the hair with sweet steam and then drying it with hot air.'' Regardless of the user's skills, anyone can obtain the same effects (dehydration prevention effect, curling effect). There is no need for the troublesome operation of switching between steam and hot air.

Finally, the hot air course is when the contact point C is switched.

In this case, the power to the electromagnetic valve 39 is cut off at the same time as the switching, so the water supply to the water absorbing body 21 is immediately cut off, and the heater 27 of the steam generator 11 also stops generating heat. Motor 1
4 rotates at high speed because the resistor R is not used. As a result, a large amount of hot air can be obtained. This has the same function as a conventional curl dryer, and is used for washing, drying, and setting hair.

With this structure, this hair curler can control the water supply tank 13 by the thermo switch 29 and the solenoid valve 39.
After the heater 27 raises the water to a certain temperature, the water absorbent body 2
1, the supplied water is reliably turned into steam and is safe because it is not discharged in the form of hot water droplets. In addition, since the valve of the water tank 13 is a solenoid valve 39 and is closed at the same time as the heater 27 is turned off, excess water flows into the water absorbing body 21 (9
) First, water droplets (hot water) do not leak to the outside.

A second embodiment of the invention is shown in FIG. That is, this hair curler has a solenoid valve 39 and a thermoswitch 29.
A bimetal type thermal valve 57 with a valve is used instead of the bimetallic thermal valve 57, and the bimetallic 5
8 is fixed at one end, and the water inlet 22 is closed by a valve 59 at the other end. When the hot plates 19 and 20 are heated to a predetermined temperature by the heater 27, they curve as shown in the imaginary line and open the valve.

Water is supplied to the water absorbent body 21, and steam is generated.

When the Q temperature drops due to a power outage of the heater 27, it returns and closes the valve.

As described above, the hair curler of this invention supplies water to the water absorbing body when the water absorbing body is heated to a certain temperature, so that complete steam can be ejected from the attachment, making it possible to This has the effect of avoiding problems such as hair damage caused by high-temperature water droplets being discharged.
