Abstract

PURPOSE:To prevent a misoperation and to improve the operability of an operation button by causing an operating force necessary for the changeover of respective operation buttons to be different in sizes and identifying the operation button with the touch feeling of hands. CONSTITUTION:When a switch mounting button 10 is operated with pressing into a main body case against a spring 28, the engagement of an engaging clock 26 is released and a blowoff nozzle 2 can be removed from a dryer 1 main body. When a rapid cooling button 15 is operated with pressing against the restoring forces of a spring arm 31 and a plunger 14a, a base 30 is made to sink by being vibrated in making a supporting point shaft 32 into a center, the plunger 14a is pressed in by a cam piece 33, and a condition is switched to an off-condition. Here, the operating forces of the switch mounting button 10 and rapid cooling button 15 are made different in sizes, especially, the operating force of the rapid cooling button 15 is set to be smaller than the operating force of the switch mounting button 10 made into the object of the misoperation, and the button to be operated can be clearly identified by the touch feeling. Consequently, even in the case of operating the switch mounting button 10 by mistake, the misoperation can be recognized, and the switch mounting button 10 can be prevented from being switched.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a hair treatment method that enables efficient hair treatments such as hair plowing and curling by replacing several types of blow-out nozzles with brushes that have been made into attachments. Regarding the dryer,
Centrally placed on the outside of the dryer. This is intended to improve the operability of operation buttons for operation control and attachment replacement.

[Conventional technology]

In this type of hair dryer, a slide button for switching the operating state between cold air, weakly warm air, and strong hot air, and a push button for replacing the attachment (hereinafter referred to as the "replacement button") are arranged adjacent to each other on the outer surface of the main body case. There is something (
Utility Model Application Publication No. 62-117904).

Furthermore, in addition to the slide button, there is also a push button (hereinafter referred to as the "quenching button") that switches the operating state from strong hot air to strong cold air, and this button is placed adjacent to the slide button. 57-51402).

This quench button.

It is used to firmly attach the hair (1) For example, after heating the hair wrapped around a blowing nozzle with a brush with strong hot air, (2)
Used to generate strong cold air to set curls, etc. Note that when the quenching button is pushed in, the power supply to the heater is stopped, or the driving rotation speed of the fan motor is increased, so that the amount of air blown is rapidly increased.

[Problem to be solved by the invention]

In hair dryers in which the above-mentioned replacement button, slide button, and quenching button are arranged together on the outer surface of the case, the replacement button and the quenching button, which are all push-operated, are often operated by mistake. In particular, when setting curls, the hair is wound around the brush part while the hair dryer is running, so the positions of the buttons are often confused, and the buttons are often groped by hand, which can lead to incorrect operation. was likely to occur. If you press the replacement button by mistake, the brush-equipped blow-out nozzle will separate from the main body case, which will not only disrupt the curl shape but also cause the nozzle and the main case to fall and be damaged.

By the way, if the quenching button is changed to another operating method such as a slide type or a snap type, the above-mentioned erroneous operation may be resolved. However, most of the quenching buttons are used only for a few seconds when necessary, and are operated repeatedly and frequently.
From the point of view of ease of operation, the push type is advantageous9.
It is desirable that the button be of the push type, since it is necessary to operate the button by hand.

This invention has been proposed in view of the above.

In hair dryers where push-operated replacement buttons and quenching buttons are arranged in a concentrated manner, the operation force required to switch each operation button is different in size, and the operation button being operated can be identified by the touch of the hand to prevent incorrect operation. The purpose is to prevent this and improve the operability of the operation buttons.

[Means to solve the problem]

In this invention, the operating force of the replacement button 10, which is subject to erroneous operation, is set to be large, and the operating force of the rapid cooling button 15, which is frequently used and is often used in a groping state, is set to be small. 10 and 15 can be distinguished by touch.

Specifically, the three mutual action buttons 10 and 15 are energized to return to the standby position. The biasing forces of the spring members 28 and 31 are set to be large or small to differentiate the operating force. In order to ensure tactile identification, it is preferable that the difference in operating force between the quenching button 15 and the replacement button 10 be approximately 5 to 10 times.

[Effect]

Since the switching operation force of the replacement button 10 is sufficiently larger than the operating force of the quenching button 15, the replacement button 10 will not be switched even if the button is pressed by mistake. can do.

〔Example〕

An embodiment of the hair dryer of the present invention will be explained with reference to FIG. 1 and FIG. 7.

In Fig. 3, the hair dryer consists of a dryer main body 1 that sends cold air or hot air, and several types of brush-equipped blow-off nozzles 2 that are removably attached to the dryer body 1. Replace nozzle 2 for drying and hair blowing.

It is designed to perform hair treatments such as curl setting.

The dryer main body 1 has a heater 4, a fan 5, a motor 6 for driving the fan, etc. arranged in a cylindrical main body case 3 which also serves as a grip, and a suction lower and an air outlet 8 are provided at the left and right ends. A blow-off nozzle 2 with a brush is externally attached to the blow-off port 8 and is held in place by a replacement button 10 provided on the side of the case 3 of the main body.

In FIG. 1, the replacement button 10 is supported in a main body case 3 so as to be retractable, and a compression coil spring (spring member) 28 is installed between the inner surface of the replacement button 10 and a spring receiving wall 25 inside the case. Pressure is applied to the posture. Replacement button 10
is integrally provided with an engaging claw 26, which engages with an engaging recess 27 provided in the case 16 of the blow-off nozzle 2 to hold the case 16 in place. When the replacement button 10 is pressed into the main body case against the spring 28, the engagement claw 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 IO,
A slide button 13 for switching and operating a slide switch 12 and a quenching button 15 for switching and operating a quenching switch 14 are arranged adjacent to each other on this panel 11. That is, in the dryer main body 1, the replacement button 10, the slide button 13, and the quenching button 15 are centrally arranged on the outer surface of the case near the air outlet 8.

The brushed blow-off nozzle 2 shown in FIG.

It is mainly used for simple drying or hair plowing, and brushes 17 are attached in multiple rows to an example of a hollow case 16, with a large number of air holes 18 between the rows.
It becomes open. In addition to this blow-out nozzle 2, a nozzle suitable for curl setting is also available as an attachment.

The air sucked in from the suction lower by fan 5 and pressurized is
The air is heated by the heater 4 and fed to the blow-off nozzle 2 through the blow-off port 8, and is blown out from the blow-off port 18 in a dispersed manner.

In Fig. 1, one main body case 3 is made by butting together two halves of the case 3a and 3b, which are divided into the front and back.
The switch panel 11 is sandwiched and fixed between both cases 3a and 3b. A switch section 21 is formed by protruding partition walls 20 from both cases 3a and 3b in an opposing manner on the lower inner surface of the switch panel 11, and a slide switch 12 and a rapid cooling switch 14 are fitted into this section 21. are doing.

The slide switch 12 controls energization of the heater 4 and the motor 6, and sequentially switches the operating state from OFF to cold air, weak air, and strong hot air. In FIG. 5, the slide switch 12 has five connection terminals from ■ to ■, and the state in which the slide button 13 is retracted toward the suction lower side is the off position.
By sequentially moving forward in the direction of arrow P in FIG. 2, the terminals are connected as shown in the table, and the operating state is switched. The rapid cooling switch 14 is a normally closed push switch, and is interposed in the circuit between the terminal (2) and the heater 4a for use in weak salt air. When this switch 14 is turned off, the power supply to the heater 4a for warm air of 9°C is stopped, and at the same time, the voltage value applied to the rectifier circuit 22 increases and the rotational speed of the motor 6 increases.

23 is a control resistor, and the resistance value of the heater 4a for slightly warm air is 15.7Ω.1 is the resistance value of the heater 4b for strong hot air.
When the resistance value is 9Ω, the resistance value of the control resistor 23 is set to 112Ω. 24 is a temperature fuse.

As mentioned above, the quench 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 retractable.

Switching is performed by pushing the button. In FIG. 4, the quenching button 15 has a circular base 30, and a spring arm (spring member) 31 and a fulcrum shaft 3 are provided on one inner surface of the base 30.
2 is formed to protrude in a T-shape, and a cam piece 33 for pushing and operating the plunger 14a of the switch 14 and a retaining piece 34 are provided protrudingly on the other side. Furthermore, a notch 35 corresponding to the pushing stroke is formed in the inner surface of the base 30. The inner surface of the switch panel 11 is provided with a shallow groove 36 for accommodating the spring arm 31, a holding groove 37 with a semicircular cross section for supporting the fulcrum shaft 32, and a rib 38 for guiding the retaining piece 34.

After fitting the spring arm 31 and the support shaft 32 into each of the above-mentioned grooves 36 and 37, when the quenching switch 14 is inserted between the base 30 and the partition wall 20 and installed, the fulcrum shaft 32 is connected to the quenching switch 1.
4 and the holding groove 37, and the quenching button 15 is held and fixed so as not to be able to move. In this assembled state, the plunger 14a projects laterally from the side wall of the switch case and is in contact with the cam piece 33. Further, the spring arm 31 is supported on the slope at the far end of the groove 36 and is spaced apart from the groove bottom. This groove bottom and spring arm 31
The gap between the base portion 30 and the base portion 30 is a deflection margin for the spring arm 31, and in this state, the base portion 30 is urged by the deformation stress of the spring arm 31 into a standby position in which it protrudes toward the outer surface of the switch panel 11.

As shown in FIG. 6, when the quenching button 15 is pushed in against the return force of the spring arm 31 and plunger 14a, the base 30 retracts while swinging about the fulcrum shaft 32.
The plunger 14a is pushed in by the cam piece 33 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. In this way, if the switch structure is such that the operating direction of the quenching button 15 and the direction of ejection and withdrawal of the plunger 14a are orthogonal, the quenching button 15 and the quenching switch 1
4 can be placed closely adjacent to each other, and both members 14 and 15 can be assembled within the range of the operating stroke of the quenching button 15 with the sui-nochi cases overlapping each other. In other words, the quenching button 15 and the quenching switch 14 can be compactly arranged in a small space within the single body case 3, and the degree of freedom in their installation positions can be improved. Furthermore, since the space occupied in the installed state can be reduced, the space occupied by the heater 4 can be set larger, which is advantageous in reducing the outer diameter of the two-body case 3.

As is clear from the biasing structure of the quenching button 15 described above, the operating force required to switch the quenching button 15 is set to be sufficiently smaller than the operating force required to switch the replacement button 10. Specifically, the operating force for the replacement button 10 is 2 to 3 kg, and the operating force for the quenching button 15 is 200 kg.
It should be ~300g.

The tension of the compression coil spring 28 and the deformation stress of the spring arm 31 were set respectively. The larger the difference in the force on both edges, the easier it will be to identify, but around 5 to 10 times is appropriate; if this range is exceeded, the force to operate the replacement button 10 will be excessive and difficult to operate, or the quench button will become difficult to operate. The operating force of 10 becomes too weak, making it easy to cause erroneous operations. It is also difficult to identify by touch.

As described above, if there is a difference in the operating forces of the quenching button 15 and the replacement button 10, it is possible to clearly identify which button is being operated by operating two buttons. Furthermore, even if the button is pressed incorrectly, the operating force required to switch the replacement button 10 is sufficiently large.

During the switching operation, it is possible to recognize that the operation is erroneous, and it is possible to avoid switching the replacement button 10.

In addition, a replacement button 10 is provided at one end of the slide button 13, which is horizontally elongated and has a long operation stroke.
If the quenching button 15 is provided on the other end side, the quenching button 15 can be found using the easy-to-identify slide button 13 as a guide.

The quenching button 15 can be easily found, especially when groping by hand. Furthermore, although the quenching button 15 is often used in strong hot air conditions, the slide button 13 is
is displaced to the replacement button 10 side, so the quenching button 1
When pressing 5, the slide button 13 does not get in the way of the operation.

Easier to operate.

In order to further improve the degree of discrimination between the quenching button 15 and the replacement button 10 by touch, the two buttons 10 and 15 are made to have different shapes in plan view and cross-section.

It is effective to make the surface morphology different. for example,
The button shapes may be different, such as a circle and a triangle, or a square and a circle, or as shown in FIG. 8, one surface may have a protruding arc surface 40a and the other surface may have a concave arc surface 40b or a polyhedral shape 40c.

Further, one surface is provided with a large number of protrusions 40d and a group of protrusions to make it rough, and the other surface is formed to be smooth. In some cases, it may be made of different materials such as rubber and plastic, or it may have the same shape or form.
The products may be different.

In addition, the springs applied to the replacement button 10 and the quenching button 15 include, in addition to the spring members 28 and 31 shown in the embodiment,
It can also be changed to a leaf spring, wire spring, etc.

〔Effect of the invention〕

As explained above, in the present invention, the operating forces of the replacement button 10 and the quenching button 15 are varied in magnitude.

In particular, compared to the operating force of the replacement button 10, which is subject to erroneous operation, the operating force of the quenching button 15 is set to be small, so that it is possible to clearly identify which button is being operated by touch when the button is operated. . Therefore, even if the replacement button 10 is erroneously operated, it is possible to recognize the erroneous operation and prevent the replacement button 10 from being switched, thereby improving the operability as a whole. Accordingly, it is possible to effectively prevent the brush-equipped blow-off nozzle 2 from separating from the dryer main body l and the hair shape being disturbed during shaping.
