As described above, each switching knob 200,
500 and the detachable button 400 protrude from the main body case 100 at approximately the same height.For example, when the main body case 100 is placed or dropped with these facing downward, the switching knobs 200 and 500 and the detachable The external force was directly applied to the button 400, and there was a possibility that the button 400 would be lost.

An object of the present invention is to provide a hair dryer capable of solving the above-mentioned problems.

[0012]

Therefore, in order to solve the above-mentioned problems, in the present invention according to the first aspect, a switching operation body of a main switch for switching an operation mode and a hairdressing attachment are attached to and detached from a main body case. In the hair dryer provided with a detachable operation body for this purpose, a protruding portion which is taller than both operation bodies is provided between the switching operation body and the detachable operation body. Therefore, at the time of hair styling, the presence of the protruding portion does not apply a strong force to both operation bodies with fingers, and erroneous operation can be prevented as much as possible. Further, when operating one of the operating bodies, there is no risk of erroneous operation of the other operating body because the protruding part is interposed, and when the main body case is gripped, the protruding part is used as a reference for the grip position. In addition, the position of the switch can be used as a guide when groping, and the intended operation of the switch can be reliably performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a hair dryer in which a main body case is provided with a switching body for a main switch for switching an operation mode and a detachable operation body for attaching and detaching a hairdressing attachment. A protruding portion that is taller than both operation bodies is provided between the operation body and the operation body.

As the shape of the protruding portion, its contour can be formed in a plateau shape, or it can be formed in a protruding plateau shape having an internal space.

The contour being plateau-shaped means that, for example, a plurality of thin plate members are arranged upright within a predetermined range in the longitudinal direction of the case body even if the projection does not necessarily have a surface such as a side surface or an upper surface. Or, a plurality of thin plate members are similarly arranged in the width direction of the case main body, including those in which the outer shape of the projected shape is a rectangular shape. Since the belly or the like can be placed, the grip feeling during use can be improved.

Further, by forming a bulged plateau having an internal space, a sub-function switch can be provided with a margin in the internal space, wiring of lead wires and the like becomes easy, and assemblability at the time of manufacturing is improved. Can be done.

As described above, by providing the protruding portion, a strong force is not applied to the switching operation body of the main switch and the attachment / detachment operation body of the attachment when the main body case is gripped with a finger.
Erroneous operation can be prevented as much as possible. Furthermore, when operating one of the operating bodies, there is no risk of erroneous operation of the other operating body due to the interposition of the protruding portion, and the gripping position can be used as a reference when gripping the main body case. In addition, the protrusion serves as a guide for the location of the switch when groping, so that the intended operation of the switch can be reliably performed.

In the case where the projecting portion is formed as a bulged portion having an internal space, the main switch and the sub-function switch can be arranged in the internal space in a superposed state. With this configuration, it is possible to prevent the terminals of the main switch and the sub-function switch from coming into contact with each other, so that there is no danger of a short circuit or the like.

Further, in this case, it is preferable to interpose a holding plate made of synthetic resin for holding the sub-function switch between the main switch and the sub-function switch. That is,
The holding plate made of synthetic resin can also be used as an insulator, so that the contact between the terminals of the main switch and the sub-function switch can be more reliably prevented. Can be improved.

Further, a direction regulating rib for regulating the extending direction of the lead wire of the sub function switch can be provided on the holding plate. With such ribs, interference between the lead wires and the switch-switching movable projections of the main switch is avoided, and there is no danger of being caught on the switch-switching movable projections of the main switch, and the arrangement of the lead wires is easy. Therefore, both the assemblability and the operability are improved.

As described above, it is extremely significant to provide a protruding portion that is taller than both the operating members, between the switching operation member of the main switch and the attachment / detachment operating member.

Further, the operating body of the sub-function switch can be directly provided on the projection. At this time, it is preferable that the upper surface of the operation body be substantially flush with the upper surface of the protrusion.

That is, the function to be switched by the sub-function switch is, for example, a quenching switch that can cut off only the heater function when hot air is being blown out and only blow air, or a so-called turbo switch that temporarily increases the wind speed. Various additional functions are conceivable. For example, if a switch for changing the specification of the power supply voltage is used as a sub-function switch so that it can be used in a foreign country having a different power supply voltage, it is not preferable to operate the switch during hairdressing. Therefore, by adopting the above configuration, it is possible to prevent a finger from directly touching the operation body of the sub-function switch, which is normally hardly operated, and there is a danger that the power supply voltage is erroneously switched and abnormal heat is generated. Is to be prevented as much as possible.

Further, a function display section of the sub-function switch can be provided on the surface of the projecting section. That is, the function is displayed in a place protruding from the case body, which makes it easy to visually recognize, and as described above, when the specification of the power supply voltage is displayed, it can be strongly recognized. The risk of erroneous operation is reduced.

Further, a protrusion can be provided on the upper surface of the protrusion. With this projection, when the function display section is provided on the surface of the protrusion as described above, the function display displayed by printing or the like directly touches the mounting surface even if the function display section is placed with the protrusion section down. It is possible to prevent characters from being blurred.

By the way, such a projection can also be used as a guide surrounding the operating body of the sub-function switch. With this configuration, the whole shape is natural and the design is excellent.
In addition, the above effects can be obtained.

In this case, it is preferable that the upper surface of the operation body is substantially flush with the upper surface of the guide portion. That is, if the operating body projects beyond the projection serving as the guide portion, especially when the operating body is a push type, it is easy to touch with a finger, and it is easy to perform an erroneous operation.
If the switch is not operated unless it is pushed down below the upper surface of the guide portion, a slight upward protrusion is allowed. Further, needless to say, the upper surface of the operation body may be located slightly below the upper surface of the guide portion.

[0069]

[Table 1]

[0070]

[Table 2]

As shown in FIG. 12, the main switch 6 uses the terminal as the power supply side and switches the connection state between the terminals and so on, as described above.
COOL (cold air), HAIR CARE (hot air), DRY (hot air)
It is possible to switch to the basic operation modes in sequence (see Table 1).

The fan motor M is driven by a DC power supplied through a rectifier circuit 35. One input path 36 of the rectifier circuit 35 is directly connected to the terminal of the main switch 6, and the other input path 37 is On the way, a variable resistor R of 460 ohms for controlling the rotation of the fan motor M and a temperature fuse 38 operating at 183 ° C. are connected to the heater input path 23.

The heater input path 23 and the terminal of the main switch 6 are connected via a diode D which allows only one-way current flow, and the terminals are connected in parallel with the diode D.

In the input path 37, a micro switch 74 is connected in parallel with the variable resistor R. In the case of the 100V / 120V specification, the micro switch 74 is turned on in conjunction with the operation of the sub knob 70. The variable resistor R is partially bypassed. In the case of 200V / 240V, it is turned off, and the entire variable resistor R is energized.

In the heater input path 23, a thermostat 24 operating at 100 ° C. and two 66-ohm heater wires 21a and 21b are provided in series, and taps 25 provided before and after the first heater wire 21a are provided. , 26, a sub-switch 7 is interposed.

The sub-switch 7 uses the terminal as a power supply side and switches the connection state between the terminal and the terminal, thereby connecting the first and second heater wires 21a and 21b in the 100V / 120V specification. It can be switched to use in parallel, and to use it in series for 200V / 240V specifications (see Table 2).
In the figure, reference numeral 39 denotes a second thermal fuse (183 ° C.), CN
Is a smoothing capacitor.

In this embodiment, as described above, the short cylindrical guide portion 41 is slightly protruded from the upper surface 4a of the protruding portion 4 to surround the sub knob 70. Moreover,
The height of the upper surface of the sub-knob 70 and the height of the upper surface of the guide portion 41 are substantially flush with each other (preferably, the sub-knob 70 is slightly sunk). Knob 70 is protected.

That is, the hair dryer A is connected to the operation function unit S
When placed with the side facing down, as shown in FIG.
Since a slight gap is formed between the upper surface 4a of the protruding portion 4 and the placement surface G, the printed function display portion 7a does not touch the placement surface G directly and characters and the like do not fade. .

Further, since the upper surface of the guide portion 41 and the upper surface of the sub-knob 70 are substantially flush with each other, external force is less likely to be applied to the sub-knob 70. There is no such thing that the knob 70 is switched, and furthermore, during use, it is difficult for the finger to directly touch the sub-knob 70 of the sub-switch 7 which is usually not operated.
Since it is difficult to apply the rotational force, the danger that the power supply voltage is switched by mistake and the hair dryer A generates abnormal heat is prevented as much as possible. In addition, the design can be neatly designed.

The projecting portion 4 according to this embodiment has a plateau shape in which the side surfaces of the detachable button 5 side and the main knob 60 side are gently inclined, but as shown in FIG. 14 and FIG. Only one of them may be inclined, or both surfaces may be vertical wall surfaces. Further, the upper surface 4a of the protrusion 4
May be slightly curved as long as the function display section 7a is not difficult to see and the grip feel is not bad.

If the internal space Q is not formed in the protruding portion 4, two or more thin plates are provided between the detachable button 5 and the main knob 60 as shown in FIGS. The body 44 may be arranged upright along the longitudinal direction of the case body 1 at a constant interval in the width direction (see FIG. 1).
6) Alternatively, a plurality of thin plate members 45 are arranged at small intervals so as to be orthogonal to the longitudinal direction of the case body 1 (FIG. 1).
7), the profile formed by the thin plate members 44 and 45 may be plateau-shaped.

With such a plateau shape, the belly of the finger can be placed, and the grip feeling when using the hair dryer A can be improved.

Further, as shown in FIG. 18, a partition wall 46 may be provided between the detachable button 5 and the main knob 60 in a projecting manner instead of a plateau.

In this embodiment, the guide portion 41 of the sub-knob 70 is described as being formed in a flat cylindrical shape on the upper surface 4a of the projecting portion 4. However, it is not always necessary to project the projecting portion. As shown in FIG. 20, the inner surface 47a of the sub-knob insertion hole 47 formed on the upper surface 4a of the projecting portion 4 can be used as a guide portion.
If the protrusions 48 are provided, the protrusions 48 can prevent the function display portion 7a from being peeled off as described above.

In this embodiment, the sub-knob 70 of the sub-switch 7 has been described as being of a rotary type, and the upper surface thereof is substantially flush with the upper surface of the guide portion 41. Again, it is not desirable that the sub-knob 70 protrude from the upper surface 4a of the protruding portion 4 or the upper surface of the guide portion 41. However, even if it is a push type, if the switch is not operated unless it is pushed down below the upper surface of the guide portion 41, a slight upward protrusion is allowed as shown in FIG.

When the sub-switch 7 is of the push type, if the sub-switch 7 is slightly offset from the center line L passing through the main knob 60 and the detachable button 5, as shown in FIG. The possibility that the sub-knob 70 will be erroneously pressed during operation of the detachable button 5 is reduced.

Here, another configuration of the hair dryer A according to the present embodiment will be described.

In FIGS. 2 and 3, reference numeral 12 denotes a metal cap which is inserted into the outer peripheral wall of the air outlet 10 of the upper and lower split cases 1a and 1b, and is a fastening ring attached to the rear end of the outer peripheral wall of the air outlet 10. Along with 13, it is possible to more reliably hold the butted state at the front ends of the upper and lower split cases 1a and 1b. Reference numeral 14 denotes an auxiliary ring provided at the front end of the peripheral wall of the cap 12.

On the rear end side of the upper and lower split cases 1a and 1b, the lead wire C1 is formed by a half-split cord outlet tube C4, C4 supported by a radial rib 15 at the center of the suction port 11.
Of the terminal holding tube C3.
Then, the end of the swivel type power cord C having the contacts C5 and C6 (FIG. 3) is inserted into the swivel-type power cord C so as to freely contact the two terminals in the terminal holding cylinder C3. C7 is a locking projection provided inside the rear end of the cord outlet cylinder C4.
