Description

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

A first embodiment of the invention is shown in FIGS. 1 to 7. That is, in this hair curler, attachments such as a normal curling brush 3 and a blow brush 4 (Fig. 7) are removably attached to the outlet 2 of a cylindrical housing 1, and the rotating attachment is attached to the central part on the suction port 5 side. A connector 6 is provided 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 discharge port 2
A steam generator 11, a hot air heater 12, a water supply tank 13, a motor 14, and a fan 15 are arranged in order from the side to the suction port 5 side, which is upwind, and these are arranged on concentric axes approximately in the center of the cross section of the housing 1. They are arranged in the upper row, 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. There is also a course changeover switch 17 located at the position of the steam generator 11 in the housing 1.
will be provided.

As shown in FIG.
A water absorbing body 21 made of metal foam or glass fiber is sandwiched between the two, a water inlet 22 is provided at one end thereof, and a steam outlet 23 is formed at the other end.
This steam outlet 23 is connected to the outlet 2 of the housing.
towards. A heater 27 using a positive temperature coefficient thermistor (referred to as a PTC element) is installed in the side frames 24 and 25 formed on the upper and lower surfaces of the hot plates 19 and 20 via an insulating plate 26 made of alumina, and a resin 28 is molded by simultaneous molding. are doing. Furthermore, lower side frame 2

9. Detects the temperature of 20. This steam generator 11 is held in a heat-resistant cylinder 18 by a support member 30,
The space between the outer periphery of the steam generator 11 and the heat-resistant cylinder 18 serves as the ventilation passage 16. In this steam generator 11, when the heater 27 is energized and generates heat, the hot plates 19 and 20 are heated via the insulating plate 26, and the water absorbing body 21 and thermoswitch 29 are further heated. When the hot plates 19 and 20 reach a predetermined temperature suitable for generating steam, the thermoswitch 29 is operated to close 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, and steam is efficiently generated by the heat of the heater 27, which is ejected from the steam outlet 23. do.

The hot air heater 12 is a circular plate using a PTC element and has honeycomb-like porous 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 having the same shape, and are held together by a curved spring 35a of a cylindrical holder 35. It is heated by ventilation through the porous holes 12a and the ventilation holes 31, and hot air is discharged toward the steam generator 11 side. N is a temperature fuse, and 32a and 33a are terminals.

The water tank 13 has a bellows-type telescopic structure, whose axial direction coincides with the housing 1, and a fixing part 3 at one end thereof.
6 is attached, and this fixed part 36 is attached to the housing 1.
A holding frame 37 is attached to the other end and is slidably supported within the housing 1.
A compression coil spring 38 disposed around the outer periphery of the motor 14 presses the presser frame 37 to compress and bias the water tank 13 . 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, a rubber bushing 41 is provided through the housing 1, a stopper 42 is provided below the bushing 41, a valve 43 is provided below the stopper 42, and the valve 43 is pushed by a coil spring 44a.
A water injection hole 44 communicating into the water supply tank 13 is formed at the position of this valve 43. 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 injection hole 44. Press fit inside. This pressure pushes the coil spring 38 to contract and the water tank 13 to expand. When the nozzle 46 is pulled out, the valve 43 is returned to its original position by the coil spring 44a, and the water injection hole 44 is closed. 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 1.

The solenoid valve 39 is a normally closed type, and is composed of a yoke 47, a coil frame 48, a coil 49, a plunger 50 with a valve, and a return spring 51. The return spring 51 causes the valve at the tip of the plunger 50 to close the valve water outlet 52. The inside of the water tank 13 is hermetically sealed. coil 4
When the plunger 9 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 water is supplied to the water absorbing body 21 under the control of a solenoid valve 39.

The motor 14 connects the shaft 54 to the suction port 5 of the housing 1.
It is fixed in the housing 1 by a mounting arm 55 which is provided toward the side and supports the end of the coil spring 38. The fan 15 is fixed to its shaft 54.

FIG. 6 shows a control circuit of this hair curler, and the course changeover switch 17 has three interlocking changeover contacts _S1 to _S3 , and fixed contacts A to C for each contact _S1 to _S3 are simultaneously switched. R is a voltage dividing resistor of the motor, D ₁ to _{D 4} are bridge diodes, and P is a normally open contact of the thermo switch 29.

The hair curler operates in a steam course, a steam set course, and a hot air course by changing the course changeover switch 17. First, the steam course is a case where the switching contacts S ₁ to _{S 3} 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, when the hot plates 19 and 20 of the steam generator 11 reach a predetermined temperature by the heater 27, the contact P of the thermoswitch 29 closes, the coil 49 of the solenoid valve 39 is energized, and the valve water outlet 52 opens.
The water in the pipe 53 is pumped by the pressure of the coil spring 38.
The water is supplied to the water absorbent body 21 through the water absorbent body 21.
is heated and produces steam. As a result, a small amount of a mixture of cold air and steam is discharged from the outlet 2 of the housing 1 and the outlet 56 of the attachment, and when the mixture is applied to the hair, the hair becomes wet.
It can be used to correct curls or as a simple treatment steamer. At this time, a trace amount (in the example, 5/
The reason for setting the air flow to be 1 min) is to increase the density of the steam and improve the wetting characteristics (large airflow dilutes the steam and worsens the wetting characteristics).

Next, the steam set course is a case where contacts _S1 to _S3 of the course changeover switch 17 are switched to contact B. In this case, in addition to the above operation, the heater 12
generates a fever. As a result, a trace amount of hot air (Example 5
Hair can be treated with a mixture of steam and steam, and the hair curling portion of the curl brush 3 or blow brush 4 can be adjusted to a humid air condition of 80°C and 80%, for example. When hair is wrapped with such a curling brush that emits moist air, the amount of water removed from the hair is reduced, the hair is not damaged, and the curling performance is much stronger than that of conventional hot air curl dryers. can get. In addition, by being able to continuously emit a mixture of steam and hot air, compared to conventional curl dryers with steam that have the operation of ``first wetting the hair with steam and then drying it with hot air'', it is easier to use. Regardless of the person's skills, anyone can obtain the same effects (dehydration prevention effect, curling effect). Also, the troublesome operation of switching between steam and hot air is no longer necessary.

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 switching, so the water supply to the water absorbing body 21 is cut off immediately, and the heater 27 of the steam generator 11 is cut off.
Also stops the fever. The motor 14 rotates at high speed because the resistor R is no longer involved. 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 supplies water to the water absorbing body 21 after the heater 27 raises the water to a certain temperature using the thermo switch 29 and the solenoid valve 39. The water is reliably steamed and is safe because it is not discharged as hot water droplets. In addition, the valve of the water tank 13 is set to the solenoid valve 3.
9 and is closed at the same time as the heater 27 is turned off, so that excess water does not flow into the water absorbent body 21 and does not turn into water droplets (hot water) and leak to the outside.

A second embodiment of the invention is shown in FIG. That is, this hair curler uses a bimetal type thermal valve 57 with a valve instead of the solenoid valve 39 and the thermo switch 29, and one end of the bimetal 58 is installed in the water absorbing body storage part Q of the heat plates 19, 20. The valve 59 at the other end closes the water inlet 22. 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, supplying water to the water absorbing body 21 and generating steam. When the temperature drops due to power outage of the heater 27, the heater 27 returns and closes.

As mentioned above, the hair curler of this invention is
Since water is supplied to the water absorbent body when the water absorbent body is heated to a certain temperature, complete steam can be ejected from the attachment, eliminating problems such as damage to hair caused by high temperature water droplets spewed out, unlike conventional methods. This has the effect of avoiding
