Description

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

[Conventional technology]

In general, a hair dryer operates a single main control switch provided on a handle of the hair dryer to sequentially switch basic operation modes such as, for example, cool air, weak warm air, and strong warm air.

A single type of auxiliary switch is provided separately from the main control switch, and the switching operation switches the operation state from, for example, a high temperature air state to a high temperature air state, and further provides an operation button for the auxiliary switch on a blower cylinder. Switching of a single type of auxiliary switch while holding the blower cylinder is known, for example, from Japanese Patent Application Laid-Open Nos. 62-246310 and 1-11103.

[Problems to be solved by the invention]

The operation control performed by switching a single type of auxiliary switch on such a blower cylinder includes a method in which the basic operation mode is partially switched and a method in which an operation state different from the basic operation mode is obtained. For example, the one that switches between the strong hot air and the weak hot air is the former, and the one that sets the strong cold air or the intermediate hot air state is the latter. In any case, the operating state obtained by switching a single type of auxiliary switch on the blower cylinder is:
There is only one type except for the state before switching. Therefore, when performing delicate hair shaping or kinking, it is difficult to sufficiently obtain a necessary operating state only by switching a single type of auxiliary switch.

Thus, in the conventional hair dryer, the operating state obtained by switching a single type of auxiliary switch is small,
In addition, there are disadvantages such as insufficient operability when performing hair treatment by grasping the blower cylinder with respect to switching of the operation state. Especially in hairdressing salons that perform high-tech hair treatment,
There is a demand for hair dryers to have more diverse and subtle differences in operating modes.

The present invention has been proposed in view of the above, and an object of the present invention is to realize a variety of operating states and further improve the usability of a hair dryer by improving the operability of switching operating states.

[Means for solving the problem]

In the hair dryer of the present invention, for example, as shown in FIG. A main control switch 28 for controlling and sequentially switching the basic operation mode; and a plurality of types of auxiliary switches 29, different in control content, for switching between the basic operation modes or switching to an operation state different from the basic operation mode. 45 are provided respectively. A switching knob 30 for the main control switch 28 is disposed on the handle 5, and operation buttons 46 and 47 for switching the auxiliary switches 29 and 45 are arranged side by side on the upper surface of the blower cylinder 4. Numeral 46 is arranged so as to be located before and after a line P extending straight upward from an intersection C where the front surface of the handle 5 and the lower surface of the blower cylinder 4 intersect.

[Action]

Since a plurality of types of auxiliary switches 29 and 45 having different control contents are provided, various operation states in addition to the basic operation mode can be obtained by switching the respective auxiliary switches 29 and 45. For example, two auxiliary switches 29 and 45
Is provided, the operating state can be changed to three types for each basic operation mode.

Further, since the operation buttons 46 and 47 for the auxiliary switches 29 and 45 are arranged side by side on the blower cylinder 4, various operation states can be switched easily and quickly while the blower cylinder 4 is held. .

〔Example〕

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

In FIG. 2, the hair dryer is a dryer body 1
And an attachment such as the nozzle 2 which is exchangeably mounted on the outlet 24. The dryer body 1 has a blower unit 3 for blowing and supplying external air and pressurizing the blower, a blower tube 4 for blowing out the airflow generated by the blower unit 3 in a horizontal direction, and a protrusion protruding downward from the outer surface of the blower unit 3. And a handle 5 to be provided.

The dryer main body 1 includes a hollow main body case 6, a blower fan 7, a motor 8,
It is composed of a heater 9 and various electric components. The main body case 6 is joined integrally with screws 6c by abutting divided cases 6a and 6b of substantially the same shape divided into right and left.

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

As shown in FIG. 5, a rubber is provided between the mounting seat 15 of the motor case 14 and the screw boss of the body case 6 to suppress the transmission of vibration to the body case 6 until the fan 7 and the motor 8 are generated. A vibration absorber 16 made of
Is stopped with screw 17. The vibration absorber 16 is formed in a slightly thick washer shape, and is interposed in each of the three mounting seats 15.

The fan 7 is a suction opening that opens on the left and right side walls of the fan chamber 12.
Inhale outside air from 18. The outside surface of the suction port 18 is a partially spherical shell-shaped, punched metal suction port grill.
Covered with 19. The suction port grill 19 and the opening plane 18a of the suction port 18 are adjacent to each other. In this case, suction grill 1
If both the opening 9 and the opening plane 18a are substantially parallel, there is a problem that the inside of the fan chamber 12 can be seen through the punching holes of the inlet grille 19, and hair, dust, and the like are easily sucked. In order to avoid such inconveniences, the left and right side walls of the fan chamber 12 are formed stepwise inward and outward at the central portion and the peripheral edge, and the stepped portion is defined as an opening plane 18a of the suction port 18. That is, the suction port 18 is formed such that the opening plane 18a greatly intersects the face wall of the suction grill 19.

The blower tube 4 is formed by a tube opening 21 on the side of the main body case 6 that is continuous with the peripheral wall of the fan chamber 12, and a nozzle tube 22 that is externally fixed to a protruding end of the tube opening 21. Nozzle tube 22 from the middle of tube mouth 21
A heater 9 and an outlet grille 23 for emitting far-infrared rays are arranged near the front end of the heater. The heater 9 is wound on an insulating plate having a cross-shaped cross section according to a conventional method. The outlet grill 23 is formed by applying a far-infrared radiation paint on the surface of a lattice-shaped metal substrate, and is fitted and fixed to the inner end of the outlet 24 of the nozzle cylinder 22.

As shown in FIG. 2, the barber shop often uses the blower cylinder 4 rather than the handle 5 in particular. This is because it is easier to use while holding the blower tube 4. For this purpose, anti-slip ribs 25 are integrally formed on the lower half peripheral surface of the cylinder opening 21 and the upper half peripheral surface of the nozzle cylinder 22, respectively. In addition, the thickness of the nozzle cylinder 22 is gradually increased toward the outlet 24 with reference to the end on the cylinder port 21 side, thereby preventing the surface temperature from increasing. For details, see the nozzle cylinder
The inner diameter of the cylinder 22 gradually decreases toward the outlet 24, and the outer diameter of the cylinder gradually increases. This corresponds to the fact that the temperature distribution during use tends to be lower on the cylinder opening 21 side and higher as it approaches the tip of the nozzle cylinder 22, and mainly due to the heat insulating effect of the cylinder wall. The temperature has been reduced.

Even if the outer diameter of the nozzle cylinder 22 is uniformly increased, almost the same heat insulating effect can be obtained. In this case, however, the blower cylinder 4 becomes thicker and it is difficult to grasp, and the finger can be freely held in the grasped state. It is inevitable that it will be difficult to move.

The interior of the handle 5 includes the partition 11 described above and the partition
A partition wall 27 protruding laterally from the upper end of the partition 11 is separated from the fan chamber 12, and the main control switch 28 is disposed in a vertical position in the partition room, and is positioned above the main control switch 28. The second auxiliary switch 29 is disposed. A switching knob 30 for operating the main control switch 28
Are slidably supported on the outside of the front surface of the handle 5. The switching knob 30 switches the main control switch 28 via a connecting plate 31 provided inside the handle 5.

As shown in FIG. 2 and FIG.
Is formed in a U-shaped cross section in conformity with the peripheral shape of the handle 5. Similarly, a finger contact rib 32 is protruded along the peripheral surface of the switching knob 30 so as to have a U-shaped cross section, and the protruding length is set larger. When the finger pad rib 32 is formed in this manner, the operation of the switching knob 30 can be performed from any portion of the front half peripheral surface of the handle 5.

In FIG. 4, a power cord 33 is introduced into the handle 5 via a cord armor 34 fixed to the lower end of the handle 5 and is connected to the main control switch 28. The cord armor 34 is formed of a hook-type coil spring, and is formed by integrally bending a lower end of a hook ring 35 for hooking on a wall or the like. Code Armor 34
When the power cord 33 breaks in or near
There is a risk of electric shock through the cord armor 34. In order to prevent this, the power cord 33 is covered with a transparent protective tube 36 over the portion where the cord armor 34 passes and before and after it.

As described above, when the power cord 33 is disconnected, it is necessary to disassemble the main body case 6 and reconnect the cord 33. However, when this repair work is performed, the entire body case 6 is disassembled, and the disassembly and reassembly require much labor. In order to resolve such inconvenience, as shown in FIG.
In 6a, a repair opening 37 is formed by omitting the lower half of the handle portion, and the opening 37 is opened and closed by a separate cover 38 formed in the same shape as the omitted portion. . The cover 38 is fixed to the opposing split case 6b with screws 39, and can be removed from the handle 5 simply by pulling out the screws 39.

In FIG. 4, a switch compartment 41 is provided on the upper surface of the blower tube 4 and adjacent to the blower 3. The switch compartment 41 is partitioned by a switch panel 42 sandwiched and fixed between the left and right split cases 6a and 6b, and a partition wall 43 protruding from both split cases 6a and 6b so as to face each other. Is a vertical wall 44 provided on the inner surface of the switch panel 42, which is divided into two front and rear chambers. A first auxiliary switch 45 and an operation button 47 for switching the first auxiliary switch 45 are disposed in the front compartment, and an operation button 46 for switching the second auxiliary switch 29 and a return spring 48 are disposed in the rear compartment. doing. That is, the two operation buttons 46 and 47 are arranged side by side so that each of them is exposed on the switch panel 42. The operation buttons 47 and 46 are connected to the handle 5 as shown in FIG.
Are arranged before and after a line P extending straight upward from an intersection C where the front surface of the air blower 4 and the lower surface of the blower cylinder 4 intersect.

A vertically long operation rod 49 is fixed below the operation button 46 in order to switch the second auxiliary switch 29 provided inside the handle 5. The operating rod 49 extends longitudinally in the vicinity of the outlet of the fan chamber 12, and its lower end is close to the switching piece 29 a of the second auxiliary switch 29. In order to position the operation rod 49 and guide the operation rod to move up and down, guide recesses 50 are cut out at the protruding end of the partition wall 11 and the partition wall 27, respectively. 51 is a return spring.

6 and 7, the operation button 47 for the first auxiliary switch 45 has an oval base 53.
A spring arm 54 projects from the center of one side, and a locking claw 55
To protrude. Further, a fulcrum rib 56 on the lower surface of the base 53 and a cam piece 5 for pushing the switching piece 45a of the first auxiliary switch 45 into operation.
7 is protruded. A fulcrum boss 58 protrudes from an upper surface of the protruding end of the spring arm 54. A button 59 is bulged at the center of the upper surface of the base 53.

On the inner surface of the switch panel 42, a fulcrum hole 61 corresponding to the fulcrum boss 58 is formed adjacent to the base end of the vertical wall 44. Further, a projection 62 for keeping the operation button 47 in the ON posture is formed on the front end side on the inner surface.

The operation button 47 is incorporated from the inside of the switch panel 42, and its fulcrum boss 58 is fitted into the fulcrum hole 61. In this state, the fulcrum rib 56 is in contact with the upper surface of the first auxiliary switch 45. The locking claw 55 is adjacent to one side end of the projection 62 as shown in FIG. 7, and the cam piece 57 is in close proximity to the switching piece 45a.

The operation button 47 can be tilted up and down using the fulcrum rib 56 as a fulcrum, and when the operation button 47 is pressed, 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 operation 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 swung horizontally around the fulcrum boss 58. When the operation button 47 is swung clockwise while the operation button 47 is being pushed in, the locking claw at the tip is
The 55 enters the lower surface of the projection 62 and is received and supported, and keeps the operation button 47 in the ON state. That is, the operation button
The 47 can turn on and off the first auxiliary switch 45 in the standby position, and can hold the on state by itself when slid in the lateral direction from the on position.

The surface shapes of the operation buttons 46 and 47 arranged side by side are different from each other so that they can be determined only by touch. Specifically, as shown in FIG. 7, a long and slightly wide determination projection 64 is formed in the center of the outer surface of the operation button 46 for the second auxiliary switch 29, and the operation button 47 for the first auxiliary switch 45 is formed. On the outer surface, a discriminating protrusion 65 formed of an inner and outer double circular rib is formed. Further, the protrusion height of the former determination protrusion 64 is set to be larger than that of the latter determination protrusion 65.

A motor 8 and a heater 9 incorporated in the dryer body 1;
The main control switch 28 and the first and second auxiliary switches 29
Electrical components such as 45 are connected as shown in FIG.

The main control switch 28 has five connection terminals, and uses the terminal as a power supply side to switch the connection state between the terminals, thereby setting the operation state to cold air, weak warm air, or strong air. The operation mode is sequentially switched to the three basic operation modes of hot air. The terminal connection state in each operation mode is shown in the table in FIG.

The motor 8 is driven by a DC power supplied through a rectifier circuit 67. One input path 70 of the rectifier circuit 67 is provided with two series-connected motor resistors 68 and 69 and a fuse 73. Further, the terminal of the main control switch 28 is directly connected to the terminal of the rectifier circuit 67 in one direction. Each is connected via a diode 71 that allows only current to pass. The other input path 72 of the rectifier circuit 67 is connected to a terminal of the main control switch 28.

In the input path 70, the motor resistance on the diode 71 side
The first auxiliary switch 45 is connected in parallel with 68. The first auxiliary switch 45 is a permanent switch. When this switch is turned on, the motor resistor 68 is bypassed, so that the voltage value applied to the rectifier circuit 67 increases, and the rotation speed of the motor 8 increases. I do. That is, the first auxiliary switch 45 functions to further 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 resistance 68, and a thermostat 75, a heater 9, and a second auxiliary switch 29 are connected to the heater input path 74 in this order, and the second auxiliary switch 29 is normally closed. The terminal 29b 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 unit A for indicating the energized state of the heater 9 is connected.
In the display section A, two light emitting diodes 76 and 77 are connected in parallel in the opposite direction, and a current controlling resistor 78 is connected in series with both diodes 76 and 77. Therefore, by turning off both diodes 76 and 77 in the cool air mode described below, turning on one light emitting diode 76 in the case of low temperature air, and further turning on the other light emitting diode 77 in the case of high temperature air,
The energized state of the heater 9 can be displayed separately.
Alternatively, the light emitting diode 77 may be a normal rectifier. By inserting the rectifier, the voltage across the light emitting diode 76 is limited by the forward drop voltage (about 0.6 V) of the rectifier. Can be protected.

Next, the operation states in the basic operation mode and the operation states when the first and second auxiliary switches 29 and 45 are switched will be described.

(Cool air mode) In this state, the terminals of the main control switch 28 are connected to the terminals and the terminals are opened. Therefore, the heater 9 is not energized, and only the motor 8 is rotationally driven (5500 rpm).

In this state, when the first auxiliary switch 45 is turned on, the current flows by bypassing the motor resistor 68, so that the motor resistance is reduced by that amount, and the voltage value applied to the motor 8 is increased, and The rotation speed increases and the air volume increases (6500 rpm).

Further, from the cold air state, the second auxiliary switch 29 is connected to the terminal.
When the switching operation is performed to the 29c side, the circuit on the heater 9 side is connected to the motor resistor 68 in parallel. That is, the heater 9
And the combined resistance of the motor resistor 68 determines the voltage value applied to the rectifier circuit 67. This combined resistance value is smaller than the single resistance value of the motor resistance 68. Therefore, the voltage value applied to the rectifier circuit 67 increases, and the motor 8
The rotation speed of the first auxiliary switch 45 is higher than when the first auxiliary switch 45 is turned on. However, since the increase in the voltage value is smaller than when the first auxiliary switch 45 is turned on, the rotation speed takes a value between the time of the cold air and the first auxiliary switch 45 being turned on. (<6500 rpm).

When the first and second auxiliary switches 29 and 45 are simultaneously turned on, the state is the same as the state where the first auxiliary switch 45 is independently turned on.

(Low-warm air mode) In this state, the terminals are connected to each other, and the terminals connected to the heater 9 are connected to each other. Therefore, the driving power is supplied to both the motor 8 and the heater 9. But,
In the circuit leading to the terminal, half-wave rectification is performed with the diode 71 interposed, so only the half-wave portion of the commercial AC power supply is used, and the voltage value applied to the motor 8 is lower than in the cold air mode. The rotation speed is also low (4000 rpm). Also,
The power consumption of the heater 9 also decreases, and the heat generation temperature also decreases (600 W).

When the first auxiliary switch 45 is turned on in the low-temperature air mode, the motor resistor 68 is bypassed as described above.
Although the number of rotations of the motor 8 increases and the air volume increases, the degree of increase is small (4500 rpm).

When the second auxiliary switch 29 is turned on in the weak warm air mode, the circuit on the heater 9 side is connected in parallel with the motor resistor 68 as described above, and the current value supplied to the heater 9 is almost ignored. Reduce to the extent possible. Motor 8
Increases (<4500 rpm). That is, in this case, the heat generation of the heater 9 is stopped from the low-temperature air state, and the state is switched to the cool-air state in which the number of revolutions is slightly reduced from the state in the cool-air mode.

By the way, when the second auxiliary switch 29 is turned on, it is also possible to simply turn off the terminal and the heater 9.
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 at the time of the weak warm air,
For this reason, the rotation speed of the motor 8 is maintained at substantially the same value as that at the time of weak warm air, and the air volume cannot be increased.

When both the first and second auxiliary switches 29 and 45 are turned on, the rotation speed of the motor 8 is increased (4500 rp) as in the case where the first auxiliary switch 45 is turned on alone.
m), the heater 9 hardly generates heat.

(High temperature air mode) In this operation mode, and terminals are connected. What is different from the low temperature mode is
That the full-wave part of the commercial AC power supply is all applied,
Therefore, the rotation speed of the motor 8 becomes the same as that in the cold air mode (5500 rpm). Further, the power consumption of the heater 9 is doubled (1200 W) in the low-temperature air mode.

When the first auxiliary switch 45 is turned on in the hot air mode, the rotation speed of the motor 8 increases and the air volume also increases (6500 rp).
m).

Further, when the second auxiliary switch 29 is switched to the terminal 29c side, the heat generated by the heater 9 is reduced to a level that can be almost ignored as in the case of the low-temperature air mode, and the rotation speed of the motor 8 increases at the same time ( <6500 rpm). That is, in this case, the state is switched from the strong hot air state to the cool air state.

When both the first and second auxiliary switches 29 and 45 are switched, a motor rotation speed similar to the state where the first auxiliary switch 45 is turned ON alone is obtained (6500 rpm), and the heater 9 does not generate heat.

The above operations are summarized in the table shown in FIG.

As described above, in each state of the basic operation mode, the first
-When the second auxiliary switches 29 and 45 are switched, various operating states can be obtained. Therefore, for example, when performing simple drying or blowing, etc., the handle 5 is held, and the main control switch 28 is switched to obtain a necessary operation state. The hair dryer can be used in various forms according to the work purpose, such as alternately switching between a wind state and a strong cold wind state.

When the hairdresser holds the blower cylinder 4, as shown in FIG. 2, the operation buttons 47 and 46 are located at the intersection C where the front surface of the handle 5 and the lower surface of the blower cylinder 4 intersect on the upper surface of the blower cylinder 4.
It is arranged so as to be located before and after the line P extending straight upward from the boundary, so that the thumb is applied to the corner where the front surface of the handle 5 and the lower surface of the blower cylinder 4 intersect each other. With the middle finger and the index finger
47 and 46 can be operated. Therefore, it is possible to easily switch the operation buttons 46 and 47 while holding the blower cylinder 4, and to switch the operation state quickly. At this time, each of the two operation buttons 46 and 47
Since the discriminating protrusions 64 and 65 having different shapes are provided, the operation buttons 46 and 47 can be discriminated only by the tactile sensation of the finger, and erroneous operation can be prevented.

(Another embodiment example)

In the above embodiment, the first auxiliary switch 45 functions as an air volume increasing switch, and the second auxiliary switch 29 functions as a switch for simultaneously stopping the function of the heater 9 and increasing the air volume. Both 29 and 45 can be modified to perform different functions.

For example, the second auxiliary switch 29 is interposed in a circuit on the terminal side continuous with the input path 70, and this switch 29 is connected to the terminal 29.
When the circuit is switched to the c side, if the circuit leading to the terminal is turned off, two to four kinds of air volume changes are performed for each state of the basic operation mode, including the state change by the first auxiliary switch 45. Can be realized. That is, high / low switching can be performed with respect to the amount of air blown.

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

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

Regarding the discrimination of the two operation buttons 46 and 47 by the tactile sensation, the following means can be adopted other than making the shapes of the discrimination protrusions 64 and 65 different.

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

The two operation buttons 46 and 47 are displaced in the circumferential direction according to the tip positions of the index finger and the middle finger when the blower cylinder 4 is gripped. When both operation buttons 46 and 47 are push buttons, and are provided at positions shifted in the circumferential direction as described above, the center axes of the operation buttons 46 and 47 are directed toward the center of the blower cylinder 4. It is preferable to set so as to intersect.

The operation force or operation stroke required for switching between the two operation buttons 46 and 47 is made to be different from each other.

Further, as a mutual relationship between the two operation buttons 46 and 47, when one of the operation buttons is switched, the other operation is locked, or when the operation is simultaneously switched,
Only the switch on the priority side is switched to the ON state, and the switching can be sequentially forced.

It is not always necessary to use a centrifugal fan 7 as a blowing mechanism of the dryer body 1. For example, it may be configured to send air by an axial fan.

〔The invention's effect〕

As described above, according to the present invention, apart from the main control switch 28 for sequentially switching the basic operation mode, a plurality of types of control different in the control content for performing operation different from the basic operation mode or switching between the basic operation modes. Auxiliary switch 29
・ Because 45 is provided, the operating state of the motor 8 and the heater 9 is changed suddenly or slightly.
A wide variety of driving conditions can be obtained, and it can well cope with advanced hair styling techniques. In addition, these auxiliary switches 29
Each of the operation buttons 47 and 46 for switching the position 45 is located on the upper surface of the blower cylinder 4 before and after a line P extending straight upward from an intersection C where the front surface of the handle 5 and the lower surface of the blower cylinder 4 intersect. Therefore, even when the hairdressing operation is performed while holding the blower cylinder 4, the switching operation of each of the auxiliary switches 29 and 45 can be easily and quickly performed, and the usability is extremely good.
