Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair which is capable of efficiently performing a hair treatment such as a hairbrow or a curl by replacing several types of attached blow-off nozzles with a brush. This is to improve the operability of operation buttons for operation control, attachment replacement, etc., which are collectively arranged on the outer surface of the dryer.

[Conventional technology]

In this type of hair dryer, a slide button that switches the operation state between cold, weak, and hot air and a push button for attachment replacement (hereinafter referred to as a replacement button) are arranged adjacent to the outer surface of the main body case. (Japanese Utility Model Publication No. Sho 62-117904).

Further, apart from the slide button, there is a push button (hereinafter referred to as a quenching button) for switching an operation state from a hot air to a strong cold air, which is provided adjacent to the slide button. 57-51402). This quenching button is used to firmly curl the hair. For example, after heating the hair wrapped around the brush-equipped nozzle with high-temperature air, generate a strong-cool air and perform curl setting. use. When the quenching button is pressed, the power supply to the heater is stopped or the driving speed of the motor for the fan is increased, so that the amount of blown air rapidly increases.

[Problems to be solved by the invention]

In the hair dryer where the above replacement button, slide button and quenching button are collectively arranged on the outer surface of the case,
In either case, the replacement button and the quenching button, which are both pushed, are often operated by mistake. In particular, during curl setting, the positions of the buttons are often confused because the hair is wound around the brush while rotating the hair dryer, and the buttons are often operated by hand. It was easy. If the replacement button is pressed by an erroneous operation, the blowout nozzle with brush separates from the main body case, and not only the curl shape is disturbed, but also the nozzle and the main body case may fall and be damaged.

By the way, if the quenching button is changed to another operation method such as a slide type or a snap type, the above erroneous operation may be eliminated. However, most of the operation modes of the quenching button are used only for a few seconds when necessary, and are operated repeatedly and frequently. Therefore, in terms of easiness of operation, the push type is advantageous. Yes, it is desirable to use the push type because it is necessary to operate the hand-holding button.

In addition, although the operability of the quenching button has been improved by setting the operating force of the quenching button to be small, the quenching button has been easily pushed in with the palm of the hand when the curl set is performed by gripping the main body case, causing a malfunction.

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and in a hair dryer in which a replacement button and a quenching button that are operated by a push operation are collectively arranged, the operating force required for switching each of the operation buttons is changed to be large and small. An object of the present invention is to identify an operation button being operated by a tactile sensation of a hand to prevent an erroneous operation, and improve operability of the operation button.

[Means for solving the problem]

In the present invention, the operation force of the replacement button 10 is set to be large, the operation force of the quenching button 15 that is frequently used and often used in the hand-raising state is set to be small, and the two operation buttons 10 and 15 are distinguished. In addition to making it possible to perform the tactile sensation, the outer surface of the main body case 3 and the operation surface of the quenching button 15 are made substantially the same surface, and when the curl set is performed by grasping the outer surface of the main body case 3, the erroneous operation of the quenching button 15 set to a small operating force Is prevented.

Specifically, the urging force of the spring members 28 and 31 for urging the two operation buttons 10 and 15 to return to the standby posture is set to be large or small, so that the operation force is differentiated. In order to ensure tactile identification, the difference in operating force between the quenching button 15 and
It is preferably about twice.

[Operation] Since the switching operation of the replacement button 10 is sufficiently larger than the operation force of the quenching button 15, even if the button is pressed incorrectly, the replacement button is pressed.
The switching operation of the button 10 is not performed, and it is possible to easily recognize that the operation is an erroneous operation by skin feeling, and it is possible to reliably prevent the quenching button 15 from being erroneously operated.

〔Example〕

An embodiment of the hair dryer of the present invention will be described with reference to FIGS.

In FIG. 3, the hair dryer comprises a dryer main body 1 for supplying cool air or hot air, and several types of blow-off nozzles 2 with brushes detachably mounted on the dryer body. Replace nozzle 2 and
The hair processing such as drying, hair blow, curl setting, etc. can be performed.

The dryer main body 1 has a heater 4, a fan 5, a motor 6 for driving a fan and the like arranged in a cylindrical main body case 3 also serving as a grip, and a suction port 7 and an air outlet 8 are provided at left and right ends. . The blowout nozzle 2 with a brush is externally fitted to the blowout opening 8, and is retained by a replacement button 10 provided on the body case 3 side.

In FIG. 1, the replacement button 10 is supported in the main body case 3 so as to be able to protrude and retract, and a compression coil spring (spring member) 28 mounted between its inner surface and a spring receiving wall 25 in the case stands by and stands out of the case. Press and urge to posture. The replacement button 10
An engaging claw 26 is provided integrally with the blowing nozzle 2.
The case 16 engages with the engaging recess 27 provided in the case 16 and
And retain it. When the replacement button 10 is pushed into the main body case against the spring 28, the engagement of the engagement claws 26 is released, and the blowing nozzle 2 can be removed from the dryer main body 1.

A switch panel 11 is provided adjacent to the replacement button 10. A slide button 13 for switching a slide switch 12 and a quenching button 15 for switching a quenching switch 14 are provided adjacent to the panel 11. That is, the dryer body 1
In the figure, the replacement button 10, the slide button 13, and the quenching button 15 are collectively arranged on the outer surface of the case near the outlet 8.

In FIG. 3, the brush-ejecting nozzle 2 shown in the figure is used mainly for simple drying or hair blow. The brushes 17 are mounted in a row on one side of a case 16 having a hollow inside, and the brush 17 is provided between rows. Many air ports 18 are opened. In addition to the blowing nozzle 2, a nozzle suitable for a curl set is also prepared as an attachment. The air sucked in from the inlet 7 by the fan 5 and pressurized is heated by the heater 4, sent to the outlet nozzle 2 through the outlet 8, and blown out from the outlet 18 in a distributed manner.

In FIG. 1, a main body case 3 is formed by butt-joining half-split cases 3a and 3b divided into front and rear parts, and a switch panel 11 is sandwiched and fixed between the two cases 3a and 3b. A switch section 21 is formed below the inner surface of the switch panel 11 by protruding a partition wall 20 from both the cases 3a and 3b so as to face each other, and a slide switch 12 and a quenching switch 14 are fitted into the section 21 and mounted. doing.

The slide switch 12 controls the energization of the heater 4 and the motor 6, and switches the operation state from off to cold air, weak air, and hot air in order. In FIG. 5, the slide switch 12 has five connection terminals, and when the slide button 13 is retracted toward the suction port 7 as an off position, the slide switch is sequentially advanced in the direction of arrow P in FIG. As a result, the terminals are connected as shown in the table, and the operation state is switched. The quenching switch 14 is a normally-closed push switch, and is interposed in a circuit between the terminal and the heater 4a for low-temperature air. When the switch 14 is turned off, the supply of current to the heater 4a for low-temperature air is stopped. At the same time, the voltage value applied to the rectifier circuit 22 increases, and the rotation speed of the motor 6 increases. Reference numeral 23 denotes a control resistor. When the resistance value of the heater 4a for low-temperature air is 15.7Ω and the resistance value of the heater 4b for high-temperature air is 5.9Ω, the resistance value of the control resistor 23 is 112Ω. 24 is a thermal fuse.

As described above, the quenching switch 14 is configured as a push switch. Therefore, the quenching button 15 is also supported by the switch panel 11 so as to be freely protruded and retracted, and the push operation is switched. In FIG. 4, the quenching button 15 has a circular base 30, and a spring arm (spring member) 31 and a fulcrum shaft 32 are formed on one inner surface of the base 30 in a T-shape, and the quenching button 15 is formed on the other side. A cam piece 33 for pushing the plunger 14a of the switch 14 and a retaining piece 34 are provided in a protruding manner. Further, a notch 35 corresponding to a pushing stroke is formed in the inner surface of the base portion 30. On the inner surface of the switch panel 11, a shallow groove 36 for accommodating the spring arm 31 and a holding groove 37 having a semicircular cross section for supporting the fulcrum shaft 32 are provided.
And a rib 38 for guiding the retaining piece 34.

After the spring arm 31 and the support shaft 32 are fitted in the grooves 36 and 37, the quenching switch 14 is inserted between the base 30 and the partition wall 20 and mounted. The quenching button 15 is non-movably held and fixed by being sandwiched and fixed by the holding groove 37. In this assembled state, the plunger 14a
Protrudes laterally from the side wall of the switch case, and
It is in contact with 33. Further, the spring arm 31 is received and supported by the slope at the deep end of the groove 36, and is separated from the groove bottom. The gap between the groove bottom and the spring arm 31 serves as a deflection allowance for the spring arm 31. In this state, the base 30 is urged to a standby position protruding toward the outer surface of the switch panel 11 by the deformation stress of the spring arm 31. Have been. In this standby position, the operation surface of the quenching button 15 is disposed so as to be substantially flush with the switch panel 11 forming the outer surface of the main body case 3, thereby preventing erroneous operation of the quenching button 15 during curl setting.

When the quenching button 15 is pressed against the return force of the spring arm 13 and the plunger 14a as shown in FIG.
Enters while swinging about the fulcrum shaft 32, and the cam piece 33
As a result, the plunger 14a is depressed and switched to the off state. The base 30 is recessed to a position where the notch 35 contacts the outer surface of the switch case. As described above, if the operation direction of the quenching button 15 is perpendicular to the direction in which the plunger 14a moves in and out, the quenching button 15 and the quenching switch 14 can be arranged in close proximity to each other. Both members with the switch case overlapping within the stroke range
14.15 can be assembled. That is, body case 3
In this case, the quenching button 15 and the quenching switch 14 can be compactly arranged in a small space, and the degree of freedom of the installation position can be improved. Further, since the occupied space in the installation state can be reduced, the space occupied by the heater 4 can be set large, which is advantageous in reducing the outer diameter of the main body case 3.

As is clear from the urging structure of the quenching button 15 described above, the operating force required for switching the quenching button 15 is set sufficiently smaller than the operating force required for switching the replacement button 10. Specifically, the operating force of the replacement button 10 is 2 to
The tension of the compression coil spring 28 and the deformation stress of the spring arm 31 were set so that the operation force of the quenching button 15 was 200 to 300 g. The greater the difference between the two operating forces, the easier it is to identify, but it is appropriate to be around 5 to 10 times. If it exceeds this range, the operating force of the replacement button 10 becomes too large to make it difficult to operate, or the quenching button 10 Is too weak, and erroneous operation is likely to occur. In addition, it is difficult to identify by tactile sensation.

As described above, if there is a difference in the operation force between the quenching button 15 and the replacement button 10, it is possible to clearly identify which button is being operated by performing the button operation. In addition, even if the button is pressed incorrectly, the operation force required for switching the replacement button 10 is sufficiently large, so that it is possible to recognize an erroneous operation during the switching operation, and the switching button 10 is not switched. .

In addition, if a slide button 13 with a horizontal shape and a long operation stroke is interposed, a replacement button 10 is provided at one end and a quenching button 15 is provided at the other end, the slide button 13 that can be easily distinguished is used as a guide. Since the quenching button 15 can be searched for, the quenching button 15 can be easily searched, especially in the case of hand-raising. Furthermore, the quenching button 15 is often used in a hot air condition, but when the hot air is used, the slide button 13 is displaced to the replacement button 10 side.
When the operation of pressing 15 is performed, the slide button 13 does not hinder the operation, and the operation becomes easy.

In order to further improve the degree of discrimination between the quenching button 15 and the replacement button 10 by the tactile sensation, it is effective to form the buttons 10 and 15 in different shapes in plan view and in cross section, or in different surface forms. For example, if the button shape is circle and triangle,
As shown in FIG. 8, one is formed as a projecting arc surface 40a and the other is formed as a concave arc surface 40b or a polyhedron 40c. Also, a number of protrusions 40d and a group of protrusions are provided on one surface to form a rough surface, and the other surface is formed into a smooth surface. Depending on the case, the material may be different, such as rubber and plastic, or the area may be different for the same shape and shape.

The springs applied to the replacement button 10 and the quenching button 15 can be changed to leaf springs, wire springs, etc. other than the spring members 28 and 31 shown in the embodiment.

〔The invention's effect〕

As described above, in the present invention, the operating force of the replacement button 10 and the quenching button 15 are made different in magnitude, and the quenching button 15
The quenching button 15 is arranged so that it is almost flush with the outer surface of the main body case, so that which button is operated can be clearly identified by tactile sensation. Identifiable. Therefore, even when the replacement button 10 is operated erroneously, it is recognized that the operation is erroneous, the switching of the replacement button 10 is prevented, and the operability can be improved as a whole. Along with this, the detachment of the blowing nozzle 2 with the brush from the dryer main body 1 and the disorder of the hair shape during shaping can be well resolved. Further, the operability of the quenching button 15 is improved by setting the operation force of the quenching button 15 to a small value, but the quenching button 15 is held by the hand holding the outer surface of the main body case 3.
However, this can be reliably prevented.
