Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair dryer, and is an improvement in switch operation means for controlling the operating state of a blower fan motor and heater.

[Conventional technology]

Generally, a hair dryer is configured to sequentially switch between basic operating modes, such as cold air, mildly warm air, and strong hot air, by operating a single main control switch provided on the handle of the hair dryer.

A single type of auxiliary switch is provided in addition to the above-mentioned main control switch, and by switching the switch, the operating state can be changed from a strong hot air state to a strong cold air state, for example, and an operation button for the auxiliary switch is provided on the blower tube. It is known, for example, in Japanese Unexamined Patent Publication No. 62-246310 and Japanese Utility Model Application No. tt1o3, etc., to perform a switching operation of a single type of auxiliary switch while holding the blower tube.

[Problem to be solved by the invention]

Operation control performed by switching a single type of auxiliary switch on the blast cylinder includes one that partially switches the basic operating mode, and one that obtains an operating state different from the basic operating mode. For example, the former is used to switch between strong hot air and weak salt air, and the latter is used to change to strong cold air or intermediate warm air. In any case, only one operating state can be obtained by switching a single type of auxiliary switch on the blower tube, except for the state before switching. Therefore, when performing delicate hair shaping, curling, etc., it is difficult to obtain the necessary operating conditions by simply switching a single type of auxiliary switch.

In this way, with conventional hair dryers, there are only a few operating states that can be obtained by switching a single type of auxiliary switch, and when it comes to switching operating states, the operability is insufficient when handling the hair by holding the blower tube. There were certain disadvantages. In particular, in hairdressing salons that perform hair treatments using advanced technology, there is a demand for hair dryers to be equipped with a wider variety of operating modes with subtle differences.

This invention has been proposed in view of the above, and aims to improve the usability of a hair dryer by realizing a wide variety of operating states and further improving the operability of switching operating states.

[Means to solve the problem]

In the hair dryer of the present invention, for example, as shown in FIG. A main control switch 28 that controls and sequentially switches between basic operation modes, and multiple types of auxiliary switches 29 with different control contents that switch between basic operation modes or switch to an operation state different from the basic operation mode. 45 respectively. A switching knob 30 for the main control switch 28 is arranged on the handle 5, and operation buttons 46 and 47 for switching and operating the auxiliary switches 29 and 45 are arranged side by side on the blower tube 4, respectively.

[Effect]

Since a plurality of types of auxiliary switches 29 and 45 having different control contents are provided, a wide variety of operating states can be obtained in addition to the basic operating mode by switching and operating each of the auxiliary switches 29 and 45.

For example, by simply providing two auxiliary switches 29 and 45, the operating state can be changed into three types for each basic operating mode.

In addition, since the operation buttons 46 and 47 for the auxiliary switches 29 and 45 are arranged side by side on the blower tube 4, it is possible to easily and quickly switch between various operating states while holding the blower tube 4. .

〔Example〕

1 to 9 show an embodiment of a hair dryer according to the present invention.

In FIG. 2, the hair dryer includes a dryer body 1,
It consists of an axotiment such as a nozzle 2 which is replaced and attached to the outlet 24. The dryer main body 1 includes a blower section 3 that sucks in and pressurizes external air, a blower tube 4 for blowing out airflow generated by the blower section 3 sideways, and a blower section 3.
A handle 5 is provided that projects downward from the outer surface of the handle.

The dryer main body 1 is composed of a hollow main body case 6 as a whole, and a blower fan 7, a motor 8, a heater 9, and various electrical components arranged inside the case 6. The main body case 6 is made up of left and right divided cases 6a and 6b having substantially the same shape, butted against each other and integrally connected with screws 6C.

In FIG. 4, a fan chamber 12 is defined inside the blower section 3 by a circular peripheral wall of the main body case 6 and a partition wall 11 continuous to this peripheral wall, and a fan 7 and a motor 8 are installed inside the fan chamber 12.
is located. The fan 7 is a centrifugal multi-blade fan, and is directly connected to the output shaft 13 of a concentrically arranged motor 8 and driven to rotate around a horizontal axis. The motor 8 is attached to the main body case 6 via a cylindrical motor case 14.

In order to prevent the vibrations generated by the fan 7 and motor 8 from being transmitted to the main body case 6, rubber is installed between the mounting seat 15 of the motor case 14 and the boss of the main body case 6, as shown in FIG. A vibration absorber 16 made of
It is fastened with screw 17. The vibration absorber 16 is formed in the shape of a slightly thick washer, and is interposed in each of the three mounting seats 15.

The fan 7 sucks in external air through suction ports 18 that are opened on the left and right side walls of the fan chamber 12. The outer surface of the suction port 18 is covered with a suction port grille 19 made of punched metal and formed into a partially spherical shell shape.

This suction port grill 19 and the opening plane 18a of the suction port 18 are adjacent to each other. In this case, if both the inlet grille 19 and the opening plane 18a are substantially parallel, the inlet grille 19
There is a problem that the inside of the fan chamber 12 can be seen through the punched hole, and hair, dust, etc. are easily sucked in. In order to avoid such a problem, the left and right side walls of the fan chamber 12 are formed in a stepped manner in the inner and outer directions between the center side and the peripheral side.
It is said that In other words, the opening plane 18a is the suction grill 1
The suction port 18 is formed so as to largely intersect with the face wall 9.

The blower tube 4 is formed of a tube opening 21 on the main body case 6 side that is continuous with the peripheral wall of the fan chamber 12, and a nozzle tube 22 that is externally fitted and fixed to the tip of the tube opening 21. A heater 9 and an outlet grille 23 that emits far infrared rays are arranged from the middle of the tube mouth 21 to near the tip of the nozzle tube 22. The heater 9 is wound around an insulating plate having a cross-shaped cross section in accordance with a conventional method.

The outlet grille 23 is made by coating the surface of a grid-shaped metal substrate with far-infrared radiant material, and is fitted and fixed to the inner end of the outlet 24 of the nozzle tube 22.

As shown in FIG. 2, especially in beauty salons, people often use the blower 4 by grasping it rather than by grasping the handle 5. This is because it is easier to use the blower tube 4 by holding it. For this purpose, the lower half circumferential surface of the cylinder mouth 21 and the nozzle cylinder 22
Anti-slip ribs 25 are integrally formed on each of the upper half circumferential surfaces. In addition, the wall thickness of the nozzle tube 22 is adjusted to
The temperature increases gradually toward the air outlet 24 with the first end as a reference, thereby preventing the surface temperature from becoming too high. Specifically, the cylinder inner diameter of the nozzle cylinder 22 is gradually decreased toward the outlet 24, and conversely, the cylinder outer diameter is gradually increased. This corresponds to the fact that the temperature distribution during use tends to be low on the cylinder mouth 21 side and to become higher as it approaches the tip of the nozzle cylinder 22, and is mainly due to the heat insulating effect of the cylinder wall.
2 reduction in surface temperature has been achieved.

Even if the outer diameter of the nozzle tube 22 is uniformly increased, a heat insulation effect similar to that of a blower can be obtained, but in this case, the blower tube 4 becomes thicker and becomes difficult to grip, and it is difficult to free the fingers when gripping it. The disadvantage is that it becomes difficult to move.

The inside of the handle 5 is made up of the partition wall 11 described above and a partition wall 27 that projects sideways from the upper end of the partition wall 11.
The fan chamber 12 is separated from the fan chamber 12, and a main control switch 28 is disposed in a vertically long position within this compartment, and a second auxiliary switch 29 is disposed above the main control switch 28.

Additionally, a switching knob 30 for operating the main control switch 28 is provided.
is supported on the outside of the front surface of the handle 5 so as to be slidable up and down. The switching knob 30 switches and operates the main control switch 28 via a connecting plate 31 provided inside the handle 5.

As shown in FIGS. 2 and 3, the switching knob 30 is formed to have a U-shaped cross section to match the peripheral surface shape of the handle 5. As shown in FIGS. Similarly, a finger rest rib 32 with a U-shaped cross section is provided to protrude along the circumferential surface of the switching knob 30, and the protruding length thereof is set to be large. In this way, the finger rest rib 32
, the operation of the switching knob 30 is controlled by the handle 5.
It can be done from any part of the front half of the periphery.

In FIG. 4, the power cord 33 is connected to the handle 5 through a cord armour 34 which is clamped and fixed to the lower end of the handle 5.
and is connected to the main side Jllll switch 28. The cord armor 34 is composed of a hook-shaped coil spring, and has a hanging ring 35 integrally formed at its lower end for hanging on a wall or the like. When the power cord 33 breaks within or near the cord armor 34, there is a risk of electric shock via the cord armor 34. In order to prevent this, the power cord 33 is covered with a transparent protection tube 36 at the passage portion of the cord armor 34 and over the front and back thereof.

As mentioned above, when the power cord 33 is disconnected, it is necessary to disassemble the main body case 6 and reconnect the cord 33 to Vε. However, when performing this repair work, the entire main body case 6 must be disassembled, which requires a lot of effort to disassemble and reassemble.

In order to eliminate this inconvenience, as shown in FIG. 5, in the split case 6a on the right side in the figure, the lower half of the handle portion is omitted to form an opening 37 for repair. A separate cover 38 formed in the same shape as the opening 37 closes the opening 37 in an openable and closable manner. cover 38
is fixed to the opposing split case 6b with a screw 39, and can be removed from the handle 5 by simply pulling out the screw 39.

In FIG. 4, a switch compartment 41 is provided on the upper surface of the blower tube 4 and adjacent to the blower section 3. As shown in FIG. The switch compartment 41 includes a switch panel 42 sandwiched and fixed between the left and right divided cases 6a and 6b, and both divided cases 6.
It is partitioned by partition walls 43 that protrude in opposite directions from a and 6b, and the inside thereof is divided into two rooms, front and rear, by a vertical wall 44 provided on the inner surface of the switch panel 42. A first auxiliary switch 45 and an operating button 47 for switching the first auxiliary switch 45 are arranged in the front compartment, and an operating button 46 for switching the second auxiliary switch 29 and a return spring 48 are arranged in the rear compartment. are doing. In other words, two operation buttons 4
6 and 47 are arranged side by side so that each is exposed on the switch panel 42.

In order to switch and operate the second auxiliary switch 29 provided inside the handle 5, a vertically long operating rod 49 is fixed to the lower part of the operating button 46. The operating rod 49 extends vertically near the outlet of the fan chamber 12, and its lower end is connected to the second
It is close to the switching piece 29a of the auxiliary switch 29. In order to position the operating rod 49 and guide its movement up and down, there are provided near the tip of the partition wall 11 and the partition wall 27, respectively.
A guide recess 50 is cut out. 51 is a return spring.

In FIGS. 6 and 7, the first auxiliary switch.

The operation button 47 for the chill 5 has an oval base 53, a spring arm 54 protrudes from the center of one side of the base 53, and a locking claw 55 protrudes from the center of the other side. Furthermore, a fulcrum rib 56 is provided on the lower surface of the base 53, and a switching piece 4 of the first auxiliary switch 45 is provided.
A cam piece 57 is provided in a protruding manner to operate 5a by pushing. spring arm 5
A fulcrum boss 58 is provided protrudingly on the upper surface of the tip of 4. Further, a button 59 is bulged out at the center of the upper surface of the base 53.

A fulcrum hole 61 corresponding to the fulcrum boss 58 is provided in the inner surface of the switch panel 42 adjacent to the base end of the vertical wall 44 . Furthermore, a protrusion 62 for keeping the operation button 47 in the on position is formed on the front end side of the inner surface.

The operation button 47 is assembled from the inside of the switch panel 42, and its fulcrum boss 58 is fitted into the fulcrum hole 6■. In this state, the fulcrum rib 56 is in contact with the upper surface of the first auxiliary switch 45. Further, as shown in FIG. 7, the locking pawl 55 is adjacent to one side end of the projection 62, and the cam piece 57 is closely opposed to the switching piece 45a.

The operating button 47 can be moved in and out in a tilted manner using the fulcrum rib 56 as a fulcrum, and when the operating button 47 is pushed in, the cam piece 57 switches the first auxiliary switch 45 to the on state via the switching piece 45a. When the operating force is released from this state, the operating button 47 returns to the standby state due to the elasticity of the spring arm 54, and the switch 45 also returns to the off state.

The operation button 47 can also be horizontally swung around a fulcrum boss 58, and when the operation button 47 is pressed and operated and swung clockwise, the locking pawl 55 at the tip engages with the protrusion 62. The operation button 47 is kept in the on state and continues for 7 seconds. In other words, the operation button 47 can turn on and off the first auxiliary switch 45 in the standby position, and can self-maintain the on state when it is slid laterally from the on position.

The surface shapes of the operation buttons 46 and 47, which are arranged side by side, are made to be different so that they can be distinguished by touch alone. Specifically, as shown in FIG. 7, a slightly wide discriminating protrusion 64 that is long in the left and right directions is formed at the center of the outer surface of the operation button 46 for the second auxiliary switch 29, and a slightly wide discrimination protrusion 64 is formed in the center of the outer surface of the operation button 46 for the second auxiliary switch 45. A discrimination protrusion 65 consisting of a double inner and outer circular rib is formed on the outer surface. Further, the protrusion height of the former discrimination protrusion 64 is set larger than that of the latter discrimination protrusion 65.

Motor 8, heater 9, main control switch 28, and first and second auxiliary switches 29 built into dryer main body 1
- Electrical components such as 45 are connected as shown in Figure 8.

The main control switch 28 has five connection terminals from ■ to ■, and the operating state can be controlled by switching the connection state between the terminals ■, ■, and ■, with the terminals ■ and ■ on the power supply side. It sequentially switches to three basic operating modes: cold air, weak salt air, and strong air. The terminal connection states in each operation mode are shown in the table in FIG.

The motor 8 is driven by DC power supplied via a rectifier circuit 67. One input path 70 of the rectifier circuit 67 has 2
Motor resistors 68 and 69 connected in series and fuse 7
3 is interposed therebetween, and is further connected directly to the ■ terminal of the main control ■ switch 28, and connected to the ■ terminal via a diode 71 that allows current to pass in only one direction. Further, the other input path 72 of the rectifier circuit 67 is connected to the ■ terminal of the main control switch 28 .

In the input path 70, the first auxiliary switch 45 is connected in parallel with the motor resistor 68 on the diode 71 side.

The first auxiliary switch 45 is a normally open switch, and when it is turned on, the motor resistor 68 is bypassed, so the voltage value applied to the rectifier circuit 67 increases, and the rotation speed of the motor 8 increases. do. In other words, the first auxiliary switch 45 functions to increase the air volume in each state of the basic operation mode.

A heater input path 74 is branched from between the fuse 73 of the input path 70 and the motor resistor 68, and a thermostat 75 is connected to this.
, connect the heater 9 and the second auxiliary switch 29 in this order,
The normally closed terminal 29b of the second auxiliary switch 29 is connected to the main control switch ■, and the normally open terminal 29c is connected between the two motor resistors 68 and 69. In parallel with the heater 9, a display section A that distinguishes and shows the energization state to the heater 9
is connected. The display section A has two light emitting diodes 76 and 77 connected in parallel in opposite directions, and a current control resistor 78 connected in series with both diodes 76 and 77. Therefore, by turning off both diodes 76 and 77 in the cold air mode (to be described later), turning on one light emitting diode 76 in the case of weakly warm air, and lighting the other light emitting diode 77 in the case of strong hot air, the heater 9 is energized. The status can be distinguished and displayed. Note that the light emitting diode 77 may be replaced with a normal rectifier, and by inserting the rectifier, the voltage across the light emitting diode 76 is limited by the forward voltage drop (approximately 0.6 V) of this rectifier, and the light emitting diode 76 can be protected.

Next, each operating state in the basic operating mode and the operating state when the first and second auxiliary switches 29 and 45 are switched will be explained.

(Cold air mode) In this state, the ■ terminal of the main control switch 28 is
and ■terminals are connected, and ■■terminals are open. Therefore, 1ffi electricity is not applied to the heater 9, and the motor 8
Only one part is rotationally driven (5500 rpm).

When the first auxiliary switch 45 is turned on from this state, current flows bypassing the motor resistance 68, so the motor resistance decreases by that amount, and the voltage applied to the motor 8 increases, causing the motor 8 to The rotation speed increases and the air volume increases (6500 rpm).

Further, when the second auxiliary switch 29 is switched from the cold air state to the terminal 29c side, the circuit of the heater 9 becomes connected in parallel with the motor resistor 68. In other words, the combined resistance of the heater 9 resistance and the motor resistance 68 is the rectifier circuit 6
7 will be determined. This combined resistance value is smaller than the resistance value of motor resistor 68 alone.

Therefore, the voltage value applied to the rectifier circuit 67 increases,
Although the rotational speed of the motor 8 increases compared to when cold air is being used, the increase in voltage value is smaller than when the first auxiliary switch 45 is turned on, so the value between when cold air is used and when the first auxiliary switch 45 is turned on is lower than when the first auxiliary switch 45 is turned on. (<650Qrpm).

When both the first and second auxiliary switches 29 and 45 are turned on at the same time, the state is the same as when the first auxiliary switch 45 is turned on alone.

(Weak warm air mode) In this state, the ■ terminal and the ■ terminal, and the ■ terminal and the ■ terminal leading to the heater 9 are connected, so that driving power is supplied to both the motor 8 and the heater 9. However, since a diode 71 is inserted in the circuit leading to the ■ terminal to perform half-wave rectification, only the half-wave part of the commercial AC power supply is used, and the voltage value applied to the motor 8 is the same as that in cold air mode. The rotation speed is also lower (4000 rpm).

Furthermore, the power consumption in the heater 9 is reduced, and the temperature of the heat generated is also reduced (600W).

When the first auxiliary switch 45 is turned on in the weak hot air mode, the motor resistor 68 is bypassed as described above.
Although the rotation speed of the motor 8 increases and the air volume increases, the degree of increase is small (4500 rpm).

Furthermore, when the second auxiliary switch 29 is turned on in the weak hot air mode, the circuit of the heater 9 is connected in parallel with the motor resistor 68, and the current value supplied to the heater 9 is almost ignored. reduced to the extent possible. At the same time, the rotation speed of the motor 8 increases (<450 Orpm). In other words,
In this case, the heat generation of the heater 9 is stopped from the weak salt air state, and the state is switched to a cold air state where the number of revolutions is slightly lower than that in the cold air mode.

Incidentally, when the second auxiliary switch 29 is turned on, simply turning off the connection between the ■ terminal and the heater 9 can also be done.
Heat generation of the heater 9 can be stopped. However, in this case, the voltage value applied to the rectifier circuit 67 is the same as during the mildly warm air, and therefore the rotational speed of the motor 8 maintains approximately the same value as during the mildly warm air, and the air volume cannot be increased.

When both the first and second auxiliary switches 29 and 45 are turned on, the rotational speed of the motor 8 increases to 450, similar to when the first auxiliary switch 45 is turned on alone.
0 rpm), the heater 9 generates almost no heat.

(Strong hot air mode) In this operation mode, the terminals ■ and ■, ■ and ■, and ■ and ■ are connected. The difference from the weak hot air mode is that the full wave portion of the commercial AC power is applied, so the rotation speed of the motor 8 is the same as in the cold air mode (
5500rpm).

Moreover, the power consumption of the heater 9 is twice as much as that in the weak hot air mode (1200W).

When the first auxiliary switch 45 is turned on in the strong hot air mode, the rotation speed of the motor 8 increases and the air volume also increases (650
0rpm).

Furthermore, when the second auxiliary switch 29 is switched to the terminal 29c side, the heat generated by the heater 9 is reduced to an almost negligible level, as in the case of the weak hot air mode, and at the same time the heat generated by the motor 8
The rotational speed of the engine increases (<6500 rpm). That is, in this case, the strong hot air state is switched to the cold air state.

When both the first and second auxiliary switches 29 and 45 are switched, the same motor rotation speed as when the first auxiliary switch 45 is turned on alone is obtained (6500 rpm), and the heater 9 does not generate heat.

The above operations can be summarized as shown in the table shown in FIG.

As mentioned above, in each state of the basic operation mode, the first
By switching the second auxiliary switches 29 and 45, a wide variety of operating conditions can be obtained. Therefore, for example, when performing simple drying or blowing, hold the handle 5 and change the main control switch 28 to obtain the required operating state, or when performing curling, etc., hold the blower tube 4 and, for example, Hair dryers can be used in a variety of ways depending on the purpose of the work, such as alternating between hot air and strong cold air.

When gripping the blower tube 4, a gripping posture without any weight is often chosen, as shown in FIG.

In this gripping posture, the operation buttons 46 and 47 for both the auxiliary switches 29 and 45 are provided at the gripping positions of the index finger and middle finger where it is easy to exert a large operating force. Therefore, each operation button 46, 47 can be easily switched while holding the blower tube 4, and the operating state can be quickly switched. At this time, both operation buttons 46 and 4
Since each of the buttons 7 is provided with discriminating protrusions 64 and 65 of different shapes, the operating buttons 46 and 47 can be discriminated just by the tactile sensation of the fingers, and erroneous operations can be prevented.

[Another embodiment example]

In the above embodiment, the first auxiliary switch 45 functions as an air volume increase switch, and the second auxiliary switch notch 29 functions as a switch that simultaneously stops the function of the heater 9 and increases the air volume. Both switches 29 and 45 can also be changed to perform different functions.

For example, the second auxiliary switch 29 may be interposed in a circuit on the side of the ■ terminal that is continuous with the input path 70, and when this switch 29 is operated to switch to the terminal 29c side, the circuit leading to the ■ terminal is turned off. If you keep it, the first auxiliary sui nochi 45
Two to four types of air volume changes can be realized for each state of the basic operation mode, including state changes due to the following. In other words, the amount of air blown can be switched between high and low.

Further, either one of the first and second auxiliary switches 29 and 45 can function as an emergency stop switch or as a changeover switch between basic operation modes.

Of course, two or more types of auxiliary switches can also be provided.

Regarding the identification of both operation buttons 46 and 47 by tactile sensation,
In addition to changing the shapes of the discrimination protrusions 64 and 65, the following means can also be adopted.

The operation modes of both operation buttons 46 and 47 are made different. For example, both operation buttons 46 and 47 are formed as a bush button and a slide button.

Both operation buttons 46 and 47 are arranged so as to be shifted in the circumferential direction in accordance with the positions of the tips of the index finger and middle finger when the blower tube 4 is gripped. If both operation buttons 46 and 47 are button buttons and are provided at different positions in the circumferential direction as described above, the central axes of protrusion and retraction of each operation button 46 and 47 should be aligned toward the center of the blower tube 4. It is preferable to set them so that they intersect.

The operating force or operating stroke required for switching both operating buttons 46 and 47 is made different in magnitude.

In addition, regarding the mutual relationship between the two operation buttons 46 and 47, when one is switched, the operation of the other is locked, or when they are switched at the same time, only the priority switch is turned on. It is also possible to change the state and force the switching sequentially.
4 The blowing mechanism of the dryer main body 1 does not necessarily need to use a centrifugal fan 7.

For example, it may be configured to send air using an axial fan.

〔Effect of the invention〕

As explained above, in this invention, in addition to the main control switch 28 that sequentially switches between basic operating modes, there is also a control switch that switches between different operating modes or between basic operating modes. Since multiple types of auxiliary switches 29 and 45 with different ffn contents are provided, it is possible to obtain a wide variety of operating states, such as changing the operating states of the motor 8 and heater 9 suddenly or subtly. , and can respond well to advanced hair styling techniques. In addition, each operation button 46 for switching these auxiliary switches 29 and 45.
47 is arranged side by side with the blower tube 4-, so the blower tube 4
Each auxiliary switch 2 can be
Switching between 9 and 45 can be performed easily and quickly, and is extremely easy to use.
